Description

Air mixer (1) Field of invention

The present invention relates to an air conditioner which is an indoor unit capable of purifying air purification function of indoor air.

Background of the invention

In the air conditioner of the prior art, there is also a deodorizing function, for example, a person who adsorbs an odor component by a precleaner for air cleaning provided at a suction port of an indoor unit, or has oxidation by being disposed in the middle of a blowing path. A deodorizing unit that decomposes the function to adsorb the odor component.

However, the air conditioner having a deodorizing function removes the odor component contained in the air taken in from the suction port and deodorizes it, and cannot remove the odor component contained in the indoor air or adhere to the window or the wall. Etc.

Therefore, there is an air conditioner which is provided with an electrostatic atomization device in the air supply path of the indoor unit, and the electrostatic mist having a particle size of nanometer size generated by the electrostatic atomization device is blown into the room together with the air. The odor component contained in the indoor air or the odor component attached to the window or the wall or the like is removed (for example, refer to Patent Document 1 or 2).

Further, an air conditioner is known which constitutes an electrostatic atomization device by a Peltier element, and is provided with an intake temperature detecting mechanism and a humidity detecting mechanism capable of detecting the temperature and humidity of the air taken in by the indoor unit, and detecting according to the suction temperature. The detection result of the mechanism and the humidity detecting mechanism controls the driving power of the Peltier element and the high voltage power source that applies the high voltage to the high voltage electrode. Thereby, water required for electrostatic atomization can be obtained without supplying water (for example, refer to Patent Document 3).

Further, an air conditioner is known which does not have a suction temperature detecting mechanism and a humidity detecting mechanism, but uses a correlation between the amount of dew condensation water and the amount of discharge current generated during electrostatic atomization, according to the detected discharge current. The amount and feedback control the driving power of the Peltier element, whereby stable electrostatic atomization control can be performed (for example, refer to Patent Document 4).

However, the air conditioner described in Patent Document 3 requires a cooling surface temperature measuring mechanism that can measure the temperature of the cooling surface of the Peltier element, and the control mechanism controls the voltage of the Peltier element driving power source so that the cooling surface Since the temperature of the cooling surface measured by the temperature measuring mechanism is close to the dew point temperature, there is a problem that the structure is complicated and the cost is increased.

Further, since the air conditioner disclosed in Patent Document 4 does not have the structure of the suction temperature detecting means and the humidity detecting means, the distance between the water and the counter electrode which are dew condensation on the high voltage electrode is high even if the indoor humidity is high. Shortening to produce a murmur, unable to produce an area of electrostatic fog having a desired particle size; or conversely, the room temperature is low and the Peltier element is played even The maximum capacity cannot reach the dew point temperature, and the area where ozone may be generated; or even the area where the dew point temperature is below the freezing point, there may be an electrostatic atomizing device to perform unnecessary action, which may shorten the life of the electrostatic atomizing device, or may not Achieving energy savings.

The best form for implementing the invention

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(the whole composition of the air conditioner)

The air conditioner is composed of an outdoor unit and an indoor unit that are normally connected to each other by a refrigerant pipe. Figs. 1 and 2 show an indoor unit of the air conditioner of the present invention.

As shown in Fig. 1 and Fig. 2, the indoor unit has a front suction port 2a and an upper suction port 2b as suction ports for taking in indoor air, and has a movable front panel that can be opened and closed at the front suction port 2a ( Hereinafter, the "front panel" is simply referred to as "the front panel". When the air conditioner is stopped, the front panel 4 is in close contact with the main body 2 to close the front suction port 2a. In contrast, when the air conditioner is operated, the front panel 4 is moved away from the body. The direction of 2 moves to open the front suction port 2a.

The inside of the main body 2 has a prefilter 5 disposed on the flow side of the front suction port 2a and the upper suction port 2b for removing dust contained in the air; the heat exchanger 6 is disposed on the prefilter 5 The downstream side is for exchanging heat with the indoor air taken in by the front suction port 2a and the upper suction port 2b; the indoor fan 8 is for conveying air which exchanges heat by the heat exchanger 6; the upper and lower flaps 12, The air blown out by the indoor fan 8 can be opened and closed, and the air outlet direction can be changed up and down. The left and right flaps 14 can change the air blowing direction from left to right. Further, the upper portion of the front panel 4 passes through a plurality of arm portions (not shown) provided at both ends thereof, and is coupled to the upper portion of the main body 2, and is driven and controlled by a drive motor (not shown) connected to one of the plurality of arm portions. When the air conditioner is operated, the front panel 4 can be moved forward from the position at which the air conditioner is stopped (the closed position of the front suction port 2a). Similarly, the upper and lower wing plates 12 are connected to the lower portion of the main body 2 through a plurality of arm portions (not shown) provided at the both end portions.

(Configuration of electrostatic atomization device)

Further, a ventilation fan unit 16 for ventilating indoor air is provided at an end portion on one side of the indoor unit (the left end portion as viewed from the front of the indoor unit, and the bypass flow path 22 side of the partition wall 46c to be described later). Immediately after the ventilating fan unit 16, an electrostatic atomizing device 18 is provided which has an air purifying function capable of generating electrostatic mist to purify indoor air.

In addition, the first figure shows a state in which the front panel 4 and the main body cover (not shown) covering the main body 2 are removed, and in FIG. 2, in order to make the connection position between the indoor unit main body 2 and the electrostatic atomization device 18 obvious, it is displayed as The electrostatic atomizing device 18 housed inside the main body 2 is separated from the main body 2. The electrostatic atomizing device 18 is actually in the shape shown in Fig. 3, and is attached to the left side portion of the main body 2 as shown in Fig. 1 or Fig. 4 .

As shown in FIGS. 2 to 4, the electrostatic atomizing device 18 is provided in the main flow path 20 that communicates from the front suction port 2a and the upper suction port 2b via the heat exchanger 6, the indoor fan 8, and the like to the air outlet 10. In the middle of the bypass heat exchanger 6 and the bypass flow path 22 of the indoor fan 8, and on the flow side of the bypass flow path 22, a high voltage transformer 24 and a bypass air supply fan 26 as high voltage power sources are provided, and An electrostatic atomization unit 30 and a muffler 32 having a heat dissipation portion 28 that can promote heat dissipation of the electrostatic atomization unit 30 are provided on the downstream side of the bypass flow path 22. Therefore, the high-voltage transformer 24, the bypass air-sending fan 26, the heat radiating portion 28, the electrostatic atomizing unit 30, and the muffler 32 are arranged in the state of the bypass flow path 22 in order from the upstream side. In the sleeve 34. By accommodating in the sleeve 34 as described above, the assemblability can be improved, and the flow path can be formed by the sleeve 34, so that space saving can be achieved, and the air from the bypass blower fan 26 can be surely blown to The high voltage transformer 24 or the heat dissipating portion 28 of the heat generating portion is cooled, and the electrostatic mist generated by the electrostatic atomizing unit 30 can be surely introduced into the air outlet 10 of the air conditioner, and the generated electrostatic mist can be released to be performed. Air-conditioned interior.

Further, the sleeve 34 is disposed such that the direction of the air flow flowing through the inside of the sleeve 34 in the longitudinal direction is opposite to the direction of the air flow flowing through the main passage 20, and is parallel from the front surface of the indoor unit body 2, whereby The abutment is disposed at a position overlapping the ventilation fan unit 16 from the front of the indoor unit body 2, and space saving is further achieved.

Further, although the high-voltage transformer 24 does not necessarily have to be housed in the sleeve 34, it can be cooled by ventilation in the bypass flow path, and it is possible to suppress the temperature rise or to save space. Inside the tube 34.

Here, the electrostatic atomization unit 30 hitherto known will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5, the electrostatic atomization unit 30 is configured as a plurality of Pare member 36 having a heat dissipating surface 36a and a cooling surface 36b; and the heat dissipating portion (for example, a heat sink) 28 is thermally connected. The discharge electrode 38 is electrically slidably disposed on the cooling surface 36b by an electrically insulating material (not shown); and the counter electrode 40 is spaced apart from the discharge electrode 38 by a predetermined distance. Configurator.

Further, as shown in Fig. 6, the control unit 42 (see Fig. 1) disposed in the vicinity of the ventilation fan unit 16 is electrically connected to the Pallet drive power source 44 and the high voltage transformer 24, and the Pare member 36. The discharge electrodes 38 are electrically connected to the Pallet drive power source 44 and the high voltage transformer 24, respectively.

Further, since the electrostatic atomizing unit 30 generates a static mist by discharging a high voltage from the discharge electrode 38, the counter electrode 40 may not be provided. For example, when the discharge electrode 38 is connected to the terminal of one end of the high voltage power supply and the other end of the terminal is connected to the frame, discharge can be performed between the discharge electrode 38 portion of the structure connected to the frame and the discharge electrode 38. In the case of the above configuration, the frame-connected structure can be regarded as the counter electrode 40.

In the electrostatic atomizing unit 30 of the above configuration, when the control unit 42 controls the Pallella driving power source 44 to cause current to flow through the Pappa member 36, heat is transferred from the cooling surface 36b to the heat radiating surface 36a, and the discharge electrode 38 is discharged. The temperature is lowered, so the discharge electrode 38 is dew condensation. Further, when the control unit 42 controls the high-voltage transformer 24 and applies a high voltage to the discharge electrode 38 to which the dew condensation water is attached, a discharge phenomenon occurs in the dew condensation water to generate an electrostatic mist having a particle size of a nanometer size. Further, in the present embodiment, since the negative high voltage power source is used as the high voltage transformer 24, the electrostatic mist is negatively charged.

Further, in the present embodiment, as shown in Fig. 7, the structure of the main flow path 20 includes a rear wall 46a of the frame 46, which constitutes the main body 2, and two side walls extending forward from both end portions of the rear wall 46a. (only the left side wall is shown in Fig. 7) 46b; a rear wall 48a formed by a rear guide member (air supply guide member) 48 formed under the frame 46; and two side walls extending forward from both end portions of the rear wall 48a (the 7 shows only the left side wall 48b, and the side wall (left side wall) 46b on one side of the frame 46 and the side wall (left side wall) 48b on one side of the rear guiding member 48 constitute the bypass flow path 22 from the main flow path. 20 separate partitions 46c. Further, the side wall 46b on one side of the frame 46 is formed with the bypass suction port 22a of the bypass flow path 22, and on the other hand, the side wall 48b on one side of the rear guide member 48 is formed next to the bypass flow path 22. Road blowing outlet 22b.

In the case of the air conditioner, when the cold room is started, the relative humidity of the low temperature air passing through the heat exchanger 6 of the indoor unit is high, and in the electrostatic atomizing device 18, when the Pare member 36 is provided for replenishing moisture Not only the discharge electrode 38 of the pin-shaped post element 36 but also the entire Pauer post element 36 are susceptible to dew condensation. On the other hand, when the warm room is started, since the relative humidity of the high temperature air passing through the heat exchanger 6 is low, there is a high possibility that the discharge electrode 38 of the Pare member 36 does not condense.

Therefore, as in the above configuration, the main flow path 20 and the bypass flow path 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 that generates the electrostatic mist is disposed in the bypass flow path 22, whereby the heat transfer can be passed through the heat exchanger 6. The air that has not been subjected to temperature and humidity adjustment is supplied to the electrostatic atomizing device 18. Thereby, when the cold room is started, dew condensation can be effectively prevented from occurring in the entire Pappellary element 36 of the electrostatic atomizing unit 30, and safety can be improved. Moreover, when the greenhouse is activated, electrostatic fog can be reliably generated.

The bypass flow path 22 is constituted by the bypass suction pipe 22c, the sleeve 34, and the bypass blow pipe 22d, and one end is connected to the bypass suction pipe 22c formed in the bypass suction port 22a of the frame side wall 46b to the left (general Vertically intersecting the left side wall 46b and extending slightly parallel to the front panel 4, the other end is connected to one end of the sleeve 34, and the bypass blowing tube 22d having one end connected to the other end of the sleeve 34 extends to the lower side. The other end is bent to the right, and the other end thereof is connected to the bypass air outlet 22b of the side wall 48b on one side of the rear guiding member 48. In this way, by forming a portion of the bypass flow path 22 by the sleeve 34, space saving can be achieved, and by the above-described series of structures, the electrostatic mist can be surely passed from the electrostatic atomization unit 18 through the bypass blow-off tube 22d. The induction to the main flow path 20 allows the electrostatic mist to be released into the air-conditioned room.

The bypass suction port 22a is located between the prefilter 5 and the heat exchanger 6, that is, the flow side of the prefilter 5 and the flow side of the heat exchanger 6, due to the air taken in by the front suction port 2a and the upper suction port 2b. The dust can be effectively removed by the prefilter 5, so that the dust can be prevented from intruding into the electrostatic atomizing device 18. Thereby, it is possible to effectively prevent dust from accumulating in the electrostatic atomizing unit 30, and it is possible to stably discharge the electrostatic mist.

In the present embodiment as described above, the prefilter 5 also serves as a prefilter for the electrostatic atomizing device 18 and the main flow path 20. Therefore, it is only necessary to clean the prefilter 5 during maintenance, and maintenance is not required. It simplifies the maintenance process.

On the other hand, the bypass air outlet 22b is located in the vicinity of the lower side of the heat exchanger 6 and the indoor fan 8, and in the vicinity of the air outlet 10, and the electrostatic mist discharged from the bypass air outlet 22b diffuses with the air flow of the main flow path 20. Filled the entire room. As described above, the bypass outlet port 22b is provided on the downstream side of the heat exchanger 6, and since the heat exchanger 6 is made of metal when disposed on the flow side of the heat exchanger 6, the electrostatic mist of the charged particles is mostly ( About 8 to 90% or more) is absorbed by the heat exchanger 6. Further, when the bypass blower outlet 22b is disposed on the lower flow side of the indoor fan 8, if it is disposed on the upstream side of the indoor fan 8, there is a turbulent flow inside the indoor fan 8, and the air passing through the inside of the indoor fan 8 collides with the indoor fan. During the various parts of the 8th part, a part of the electrostatic mist (about 50%) is absorbed.

Further, the main air channel 20 side of the side wall 48b on one side of the guide member 48 after the bypass air outlet 22b is provided, and the indoor fan 8 gives a constant speed of the airflow, and the bypass flow path can be provided on the main flow path 20 side of the side wall 48b. A pressure difference is generated on the 22 side, so that the main flow path 20 side becomes a negative pressure portion which is relatively low pressure with respect to the bypass flow path 22 side, and the pilot air flows from the bypass flow path 22 to the main flow path 20. Therefore, the bypass blower fan 26 may be of a small capacity, and the bypass blower fan 26 may not be provided as the case may be.

Further, the bypass blow-off pipe 22d is connected to the partition wall 46c in a direction slightly perpendicular to the air flow in the main flow path 20 at a junction point (bypass air outlet 22b) with the main flow path 20 (the rear guide member 48) Side wall 48b). Since the electrostatic atomizing unit 30 generates an electrostatic mist by the discharge phenomenon as described above, it is surely accompanied by a discharge sound, and the discharge sound has directivity. Therefore, at the junction point of the bypass flow path 22 and the main flow path 20 (the bypass air outlet 22b), the bypass flow path 22 is connected to the front panel 4 in a parallel manner, thereby making it possible to make the discharge sound not point to the position. People in front of the indoor unit or in front of the room can reduce noise.

Further, as shown in Fig. 8, the bypass blowing pipe 22d is inclined at the junction with the main flow path 20 with respect to the partition wall 46c, and when the air in the main flow path 20 is directed to the upstream side, the connection is further reduced. The effect of the noise of the discharge sound.

Further, even if the direction in which the bypass blow pipe 22d is directed is the downstream direction of the air flow in the main flow path 20, the extension line can be prevented from protruding from the mouthpiece portion 10 to the outside, thereby reducing the occurrence of the extension line. The discharge sound directly leaks from the mouthpiece portion 10 to the outside, and can also be directly incident on the user's ear, so that the noise reduction effect can be achieved.

As described above, the main flow path 20 and the bypass flow path 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 that generates the electrostatic mist is disposed in the bypass flow path 22 that bypasses the heat exchanger 6 and communicates with the main flow path 20, The air that has not passed through the heat exchanger 6 and has not been adjusted in temperature and humidity can be supplied to the electrostatic atomizing device 18, so that when the cold room is operated, condensation can be effectively prevented from being generated in the entire portion of the electrostatic wave atomizing unit 30. The safety can be improved, and the electrostatic mist can be surely generated when the greenhouse is in operation, and the electrostatic mist can be stably generated regardless of the operation mode of the air conditioner, that is, regardless of the season.

In addition, FIG. 9 shows a state in which the electrostatic atomization device 18 is mounted when the indoor unit 2 is viewed from the side, and the electrostatic atomization device 18 has a shape corresponding to the rear space of the ventilation fan unit 16, and is housed in the space.

Fig. 10 shows an electrostatic atomizing device 18A having no casing 34, which is attached to the indoor unit body 2 as shown in Fig. 11. Alternatively, it is attached to the broken line region 18B shown in Fig. 11 (the electrostatic atomizing unit 30 and the muffler 32 provided on the downstream side of the bypass flow path 22 in the electrostatic atomizing device 18 shown in Fig. 9 are substantially the same. position). The electrostatic atomizing device 18A is disposed at a position overlapping the ventilation fan unit 16 from the front or the upper surface of the indoor unit, and the electrostatic atomizing device 18A is disposed at the opening portion 62 of the ventilation fan unit 16 and damped. The portion of the air that is attracted by the ventilation fan unit 16 in the vicinity of the damper 64.

As described in more detail, the electrostatically atomizing device 18A of FIG. 10 is integrally mounted with the electrostatic atomizing unit 30 having the heat dissipating portion 28 and the muffler 32, and the electrostatic atomizing unit 30 and the muffling portion except the heat dissipating portion 28 The dampers 32 are respectively housed in respective sleeves (the unit sleeve 66 and the muffler sleeve 68), and the muffler sleeve 68 is connected and communicated with one end of the bypass blow-off tube 22d, and the other end of the bypass blow-out tube 22d Then connected and connected to the main road 20. At this time, the partition wall 46c is spaced apart from the main flow path 20, and is formed between the left side surface of the main body cover (not shown), and the accommodating portion 22e such as the ventilation fan unit 16 and the electrostatic atomizing device 18A is disposed instead of The bypass suction pipe 22c and the sleeve 34 described above constitute a bypass flow path 22 that can be accommodated in the bypass blow pipe 22d.

Further, the effect of reducing the noise in the direction in which the bypass blowing pipe 22d is directed to the main flow path 20 can be as described above, but it is not necessary, and the muffler bushing 68 can be directly connected to the bypass air outlet 22b. Thereby, the configuration of the electrostatic atomizing device 18A can be simplified. However, in order to reduce the noise, it is necessary to consider the direction problem, and it is the same as the bypass blowout pipe 22d.

As described above, the air sucked into the main body 2 through the prefilter 5 is sucked into the accommodating portion 22e by the bypass suction port 22a on the downstream side of the prefilter 5, and the direction of the air flow is opposite to the direction of the air flow flowing through the main flow path 20. The indoor unit 2 flows in parallel in the accommodating portion 22e from the front. In this manner, the heat radiating portion 28 can be cooled by the air flowing through the accommodating portion 22e, and the electrostatic atomizing unit 30 can be attached from the opening (not shown) formed in the unit casing 66.

With the above configuration, the space around the ventilation fan unit 16 overlapping the ventilation fan unit 16 can be the bypass flow path 22 from the front or the upper surface of the indoor unit, and the ventilation fan unit 16 can be effectively utilized, and electrostatic atomization can be utilized. The storage portion 22e of the device 18A or the like is saved in space. In addition, in this configuration, the high-voltage transformer 24 can be disposed in any part of the accommodating portion 22e such as the ventilating fan unit 16 and the electrostatic atomizing device 18A, and the bypass blower fan 26 is not provided.

Further, as described above, the bypass flow path 22 is configured to flow in parallel with the air flow passing through the main flow path 20 in parallel from the front surface of the indoor unit 2, whereby the partition wall 46c can be simply as described above. Since the main flow path 20 and the bypass flow path 22 are separated, the bypass flow path 22 can be easily formed, and the number of parts can be reduced.

Further, with this configuration, the prefilter of the electrostatic atomizing device 18A and the prefilter of the main flow path 20 can be shared as the prefilter 5. The effect of the sharing is as described above, and thus the detailed description is omitted here.

Further, an opening 46d may be formed in the vicinity of the lower portion of the frame 46 located at the rear of the ventilation fan unit 16 such that a pipe (not shown) to which the indoor unit and the outdoor unit are connected is pulled out. The bypass suction port 22a is formed in one opening of the accommodating portion 22e of the partition 46c (frame side wall 46b) in order to suck the air into the accommodating portion 22e, and communicates with the outside of the indoor unit through the prefilter 5, but is formed. In the opening 46d at the lower portion of the frame 46, the accommodating portion 22e is an opening that directly communicates with the outside of the indoor unit and sucks in the surrounding air. In this case, the accommodating portion 22e also serves as a bypass flow path bypassing the prefilter 5. Therefore, since the air taken in by the electrostatic atomizing device 18A is the one that flows in from the opening 46d and does not pass through the prefilter 5, the prefilter for the electrostatic atomizing device 18A may be separately provided as needed. Further, in the structure in which the opening 46d is formed, the point at which the electrostatic atomizing device 18A is provided at a position overlapping the ventilation fan unit 16 from the front or the upper surface of the indoor unit is not changed, and the accommodating portion 22e can be effectively utilized. The space is also the same.

As described above, the main air passage 20 side of the bypass air outlet 22b is provided with a predetermined speed by the indoor air fan 8, and a pressure difference is generated to become a negative pressure portion. Therefore, even if the air passage blower fan 26 is not provided, it can pass through the side. The road blowing pipe 22d cools the heat radiating portion 28 by the air guided to the main flow path 20 from the accommodating portion 22e as the bypass flow path, and the electrostatic mist generated by the electrostatic atomizing unit 30 can also be guided to the main flow path 20. And released into the air-conditioned room. Further, since the heat radiating portion 28 is disposed in the vicinity of the opening portion 62 and the damper 64 as in the broken line region 18B and the portion of the air that has been sucked into the opening portion 62 flows, the air can be cooled by the suction air of the ventilation fan unit 16. .

Further, as shown in Fig. 11, the heat radiating portion 28 of the electrostatic atomizing device 18A is disposed close to the opening portion 62 provided in the ventilation fan unit 16, and the air sucked by the opening portion 62 can further cool the heat radiating portion 28, And promoting the heat dissipation of the electrostatic atomization unit 30. Further, when the fan for ventilation is used as the ventilation fan unit 16, since the damper 64 is not provided, the heat radiating portion 28 is brought close to the suction port of the ventilation fan unit 16, whereby the heat can be cooled more efficiently. Department 28.

As described above, according to the above configuration, the main flow path 20 and the accommodating portion 22e serving as the bypass flow path are separated by the partition wall 46c, and the electrostatic atomization device 18A that generates the electrostatic mist is placed in the accommodating portion 22e, and the heat transfer device 22e can be passed. 6. The air of the unregulated temperature and humidity is supplied to the electrostatic atomizing device 18A. Therefore, when the cold room is in operation, the condensation of the entire surface of the electrostatic wave atomizing unit 30 can be effectively prevented, and the safety can be improved. When the greenhouse is in operation, electrostatic mist is surely generated, and the electrostatic mist can be stably generated regardless of the operation mode of the air conditioner, that is, regardless of the season.

(Operation control of electrostatic atomization device)

This control system sets the plural parameters as the operation permission conditions of the electrostatic atomization devices 18 and 18A, and allows the electrostatic atomization devices 18 and 18A to operate only when all the parameters indicate that the electrostatic atomization devices 18 and 18A are permitted to operate. When at least one of the parameters does not indicate the operation permission, the electrostatic atomization devices 18, 18A are prohibited from operating, whereby the unnecessary operation of the electrostatic atomization devices 18, 18A can be prevented from the viewpoint of energy saving or the life of the Pare member 36. And can prevent abnormal operation.

In the present embodiment, the following parameters are set as the operation permission conditions.

(i) The temperature and humidity of the indoor air are in the operation permitting area of the electrostatic atomizing device 18, 18A

(ii) When the number of rotations of the indoor fan 8 is equal to or greater than a predetermined number of rotations

(iii) when the electrostatic atomizing device 18, 18A is not abnormal

First, the operation permission region of the electrostatic atomization devices 18 and 18A of the above (i) will be described.

In the indoor unit, a suction temperature sensor 92 (refer to Fig. 13) that can detect the temperature of the sucked air is provided in the vicinity of the suction port (the front suction port 2a or the upper suction port 2b), and can detect the humidity of the sucked air. The humidity detector 94 (see Fig. 13) is provided, for example, on a power source substrate of the indoor unit, and sets the operation permission area of the electrostatic atomization devices 18 and 18A based on the temperature and humidity of the air taken in by the indoor unit, and senses the suction temperature. When the humidity detected by the temperature and humidity sensor 94 detected by the device 92 is within the operation permission region, the electrostatic atomization device 18, 18A is allowed to operate, and on the other hand, when the detected temperature and humidity are operating When the outside of the permitted area, the electrostatic atomizing devices 18 and 18A are prohibited from operating.

According to the above configuration, since the cooling surface temperature measuring mechanism is not required to have a simple structure, the cost is not increased, and when the detected temperature and humidity are outside the operation permission region, the electrostatic atomizing devices 18 and 18A are prohibited from operating. It can prevent noise or ozone from happening, and can achieve the effect of increasing the life of the electrostatic atomization device or saving energy.

The operation permission area of the electrostatic atomization devices 18 and 18A will be described with reference to Fig. 12 . As shown in Fig. 12, the excessive dew condensation region, the first performance outer region, and the freezing point region are set according to the air temperature and humidity inhaled by the indoor unit, and the region other than the region is set as the operation permission region. The excessive dew condensation region refers to a state in which the humidity is high (the first predetermined value or more), the distance between the water dew condensation on the discharge electrode 38 and the counter electrode 40 becomes short, and the noise is short-circuited, and noise is generated due to the short-circuit current. Or it is impossible to produce an area of electrostatic fog having a desired particle size. Further, the first performance outer region refers to a region where the humidity is low (below the second predetermined value smaller than the first predetermined value), and the Pare member 36 does not reach the dew point temperature even if the maximum capacity is exhibited, and is not in the dew condensation water and the pair. Discharge between the electrodes 40, but discharge between the discharge electrode 38 and the counter electrode 40, and there is a possibility that ozone is generated. In addition, the area under the freezing point refers to the area where the dew point temperature obtained by the humid air line diagram is below the freezing point.

That is, by setting the excessive dew condensation region to prohibit the operation of the electrostatic atomization devices 18, 18A, it is possible to prevent the noise from being generated as the indoor humidity is high, the distance between the water and the counter electrode which is excessively dew condensation of the high voltage electrode is short, or the noise is prevented. An electrostatic mist having a desired particle size cannot be produced.

Further, by setting the first performance outer region, the operation of the electrostatic atomization devices 18 and 18A is prohibited, and it is possible to prevent the occurrence of ozone even if the indoor humidity is low and the Palladium device has the maximum capability and cannot reach the dew point temperature.

Further, by operating the electrostatic atomization devices 18 and 18A by setting the area under the freezing point, it is possible to prevent unnecessary operation of the dew point temperature in the area under the freezing point, thereby shortening the life of the electrostatic atomizing device 18, 18A, or failing to achieve energy saving. effect.

Further, in Fig. 12, the upper limit temperature is set. However, since the area above the upper limit temperature is related to the size of the heat radiating portion 28, the region can be referred to as a second performance outer region. That is, as described above, when a current flows through the Pappa member 36, heat is moved from the cooling surface 36b to the heat radiating surface 36a, and the temperature of the discharge electrode 38 is lowered, whereby the discharge electrode 38 is dew condensation and moved to the heat radiating surface 36a. The heat is radiated from the heat radiating portion 28, but the size of the heat radiating portion 28 is limited in view of the storability of the electrostatic atomizing unit 30. The size of the heat radiating portion 28 is set at least in consideration of the highest set temperature (for example, 30 ° C) during the operation of the greenhouse, and is set to be equal to or higher than the highest set temperature (for example, 32 to 35 ° C). Can be roughly normal action. However, if it is above the maximum set temperature, the possibility of hindering the normal operation increases as the temperature rises. Therefore, when the detected temperature exceeds the highest set temperature at the time of the warm-up operation as the upper limit temperature, it is regarded as the second performance outer region that hinders the normal operation of the electrostatic atomizing unit 30. Further, even in the operation of the cold room, the size of the heat radiating portion 28 is also limited. For example, after the indoor temperature is lowered to 30 ° C or lower of the upper limit temperature here, the electrostatic atomizing devices 18 and 18A start to operate.

In other words, by setting the second performance outer region, it is possible to prevent the electrostatic atomization devices 18 and 18A from operating in a state where the upper limit temperature is exceeded and the Pare member 36 is not operated.

Next, the number of rotations of the indoor fan 8 of the above (ii) will be described.

The heat that has moved from the cooling surface 36b of the Pare member 36 to the heat radiating surface 36a is radiated by the heat radiating portion 28, but the number of revolutions of the indoor fan 8 detected by the number-of-rotation detecting means 96 (see Fig. 13) When the predetermined number of rotations (e.g., about 400 rpm) is less than the heat dissipation portion 28, the heat dissipation of the heat dissipating portion 28 may be incomplete, and the required cooling performance of the Pare member 36 may not be exerted. Therefore, when the number of rotations of the indoor fan 8 is equal to or greater than the predetermined number of rotations, the operations of the electrostatic atomization devices 18 and 18A are allowed. On the other hand, when the predetermined number of rotations is not completed, the operations of the electrostatic atomization devices 18 and 18A are prohibited.

Thereby, it is possible to prevent the operation of the Pare member 36 from being unstable due to insufficient heat dissipation, or to prevent the cooling performance of the Pare member 36 from being exerted, and it is impossible to obtain a predetermined dew condensation water on the discharge electrode 38. Further, when the number of rotations of the indoor fan 8 is low, the discharge sound of the electrostatic atomizing devices 18 and 18A also becomes conspicuous, and when the number of rotations of the electrostatic atomizing devices 18 and 18A is smaller than a predetermined number of rotations, the operation of the electrostatic atomizing devices 18 and 18A is stopped, and the above-mentioned operation can be avoided. The generation of noise.

Further, the failure of the high voltage transformer 24 (the abnormality of the output voltage) and the failure of the Palladium drive power source 44 (the abnormality of the output voltage) are set as the abnormalities of the electrostatic atomization devices 18 and 18A of the above (iii) by When the control unit 42 (see FIG. 13) including the electrostatic atomizing device 18 and the 18A abnormality detecting mechanism does not detect the failure of the high voltage transformer 24 or the Palladium driving power source 44, the electrostatic atomizing devices 18 and 18A are allowed to operate. On the other hand, if an abnormality is detected due to one of the failures, the electrostatic atomization devices 18 and 18A are prohibited from operating. Thereby, it is possible to prevent the electrostatic atomization devices 18 and 18A from continuing to operate in an abnormal state.

Fig. 13 is a block diagram showing the signal transmission and reception of the control unit 72 of the indoor unit and the control unit 42 of the electrostatic atomization devices 18 and 18A.

As shown in Fig. 13, the output of the suction temperature sensor 92, the output of the humidity sensor 94, and the output of the rotation number detecting mechanism 96 are input to the control unit 72 of the indoor unit, and the electrostatic atomizing devices 18, 18A The control unit 42 monitors the output value of the high voltage transformer 24 and the output value of the Palladium drive power source 44. Here, the suction temperature sensor 92 and the temperature sensor 94 use a refrigeration cycle controller that operates in a cooling room or a dehumidifying air conditioner.

Only the humidity detected by the temperature and humidity sensor 94 detected by the suction temperature sensor 92 is the operation permitting area of the electrostatic atomization device 18, 18A, and the indoor fan 8 detected by the rotation number detecting means 96 When the number of rotations is equal to or greater than the predetermined number of rotations, and the abnormality signal from the control unit 42 of the electrostatic atomization devices 18 and 18A is not input to the control unit 72, the control unit 72 of the indoor unit outputs the operation permission signal to the electrostatic mist. The control unit 42 of the devices 18 and 18A receives the operation permission signal, and the control unit 42 of the electrostatic atomization devices 18 and 18A controls the high voltage transformer 24 and the Palladium drive power source 44.

On the other hand, when the temperature detected by the suction temperature sensor 92 and the humidity detected by the humidity sensor 94 are outside the operation permission region of the electrostatic atomization device 18, 18A, or the rotation number detecting mechanism 96 detects When the number of rotations of the indoor fan 8 is less than the predetermined number of rotations, or when the abnormality signal from the control unit 42 of the electrostatic atomization devices 18 and 18A is input to the control unit 72 of the indoor unit, the control unit 72 does not output the operation permission signal. The control unit 42 of the electrostatic atomization devices 18 and 18A prohibits the operation of the electrostatic atomization devices 18 and 18A.

Further, in the block diagram of Fig. 13, the control unit 42 outputs the operation permission signal from the control unit 72 of the indoor unit to the control unit 42 of the electrostatic atomization devices 18 and 18A. However, the signal of the power supply ON may be output instead of the operation permission signal.

In the above configuration, it is a simple structure of a cooling surface temperature measuring mechanism that does not require measurement of the cooling surface temperature of the Pappa member, and the suction temperature sensor 92 and the humidity sensor 94 can also be used as the electrostatic atomizing device 18. The 18A is a detection mechanism used during air-conditioning operation other than operation, so that it can prevent cost increase.

Further, the parameters of the above (i) to (iii) are set as the operation permission conditions of the electrostatic atomization devices 18 and 18A, and in addition to the above parameters, the control unit 72 may calculate the indoor unit consumption for removing the electrostatic atomization devices 18 and 18A. The electric power allows the electrostatic atomizing devices 18 and 18A to operate when the calculated consumed electric power is equal to or less than the allowable electric power value. On the other hand, when the allowable electric power value is exceeded, the electrostatic atomizing devices 18 and 18A are prohibited from operating.

Hereinafter, this parameter will be described in more detail with reference to Table 1.

Table 1 shows an example of the consumption power of the indoor unit. It is assumed that the allowable power consumption of the indoor unit is 18 W. If the power consumed by the microcomputer (control unit 72) is 10 W, the remaining 8 W must be used to make the electrostatic atomization. The devices 18, 18A or the upper and lower wings 12, the left and right wings 14, or other drive units operate simultaneously. Therefore, when the total value of the consumed electric power calculated by removing the electrostatic atomization devices 18 and 18A is equal to or less than the allowable electric power value (for example, 14 W), the electrostatic atomization devices 18 and 18A are allowed to operate, and when the allowable electric power value is exceeded. At this time, the electrostatic atomizing devices 18 and 18A are prohibited from operating. According to the above configuration, it is possible to prevent the electric power from exceeding the allowable power of the indoor unit.

Next, an air-conditioning control performed by the human body detecting device that can detect the position of the human body in the indoor unit main body 2 and based on the position of the person detected by the human body detecting device will be described.

Figs. 14A to 14C, 15A, 15B, and 16 show an indoor unit of an air conditioner according to the present invention having a human body detecting device, and a state in which the front panel 4 closes the front suction port 2a, 15A and 15B, with respect to Figs. 14A to 14C. The figure shows the state in which the front panel 4 opens the front suction port 2a.

As shown in Fig. 16, the inside of the main body 2 is provided below the front and rear suction ports 2a except for the upper and lower flaps 12 which can change the direction in which the air is blown up and down, and the left and right flaps 14 which can change the direction in which the air is blown out. The main body 2 is further rotatably attached to the middle wing 114 via the middle wing drive mechanism 116, and the middle wing 114 is opened and closed on the side of the air outlet 10 of the front suction port 2a. Further, the front panel 4 is coupled to the upper portion of the main body 2 through the two arm portions 118 and 120 provided at both end portions thereof, and is driven by a drive motor (not shown) coupled to the arm portion 118 to operate the air conditioner. At the time, the front panel 4 is moved obliquely forward and upward from the position at which the air conditioner is stopped (the closed position of the front suction port 2a). Further, the upper and lower wing plates 12 are coupled to the lower portion of the main body 2 through the two arm portions 122 and 124 provided at both end portions thereof, and the driving method will be described later.

(Structure of human body detection device)

As shown in FIGS. 14B and 14C, in the upper portion of the front panel 4, a plurality of (for example, five) sensor units 126, 128, 130, 132, 134 are mounted in a state of protruding the main plane of the front panel 4 as The human body detecting devices, such as the sensor units 126, 128, 130, 132, and 134, are held by the sensor holder 136 as shown in FIGS. 17A to 17C. Further, as shown in Fig. 14A, the human body detecting device is covered with the mask 100, and the 14B chart shows the state in which the mask 100 is removed.

Each sensor unit 126, 128, 130, 132, 134 is disposed on the upper portion of the front panel 4, as shown in FIG. 18A, to expand the field of view of each of the sensor units 126, 128, 130, 132, and 134. (The human body position discrimination area described later) ensures the maximum distance of the far field of view. Further, as shown in Fig. 18B, by moving the front panel 4 to the front of the stop position at the start of the operation, a farther field of view can be secured, and as shown in Fig. 18C, the front panel 4 is moved to The stop position is more obliquely upwards to increase the field of view. In addition, the position of each of the sensor units 126, 128, 130, 132, 134 is not limited to the upper portion of the front panel 4, and even if the front panel is not movable, the human detecting device is mounted on the upper portion of the front panel or the upper portion of the body. It is also possible to expand the field of view more than when it is installed in the lower part.

Moreover, as shown in FIG. 18D, by providing each of the sensor units 126, 128, 130, 132, 134 to protrude from the main plane of the front panel 4, each of the sensor units 126, 128, 130, 132 and 134 are disposed further forward, and as shown in FIGS. 18B to 18D, it is possible to prevent a dead angle due to the structure of the indoor unit (for example, the front panel 4 before the upper and lower flaps 12 or the front suction port 2a is opened), and thus it is possible to expand visual field.

In this embodiment, since each of the sensor units 126, 128, 130, 132, and 134 is disposed on the front panel 4, when the front panel 4 has the front suction port 2a in an open state, each sensor unit can be As the front panel 4 moves, it protrudes more from the front.

Further, the sensor unit 126 is composed of a circuit board 126a, a lens 126b attached to the circuit board 126a, and a human body detecting sensor (not shown) mounted inside the lens 126b. The other sensor units 128, 130 132, 134 are also the same structure. Further, the human body detecting sensor is configured by, for example, detecting an infrared sensor that is unmanned by detecting infrared rays emitted from the human body, and outputting a pulse signal according to a change in the amount of infrared rays detected by the infrared sensor. Whether or not a person is present is determined by the circuit board 126a. That is, the circuit board 126a functions to determine whether or not there is an undetermined mechanism.

(The position of the person in the human body detection device is estimated)

Figure 19 shows the human body position detection area detected by the sensor units 126, 128, 130, 132, 134, and the sensor units 126, 128, 130, 132, 134 can detect whether or not someone is present in the following areas, respectively.

Sensor unit 126: area A+C+D

Sensor unit 128: area B+E+F

Sensor unit 130: area C+G

Sensor unit 132: area D+E+H

Sensor unit 134: area F+I

That is, in the indoor unit of the air conditioner of the present invention, the detectable area of the sensor unit 126, 128 overlaps with the detectable area of the sensor unit 130, 132, 134, and the use is less than the area A. The sensor unit of the number II detects whether any of the areas A to I are present.

Further, by attaching at least three human body detecting sensors to the upper portion of the indoor unit, it is possible to secondarily grasp the distance between the human body position in the room and the left and right direction with respect to the indoor unit, that is, where in the indoor floor. Figure 20 shows the detection area in the case where three human body detecting sensors are provided. In the example of Fig. 20, a human body detecting sensor detects that there is no one in the vicinity of the indoor unit, and two human detecting sensors are provided. There is no one in the area far from the indoor unit.

Returning to Fig. 19, the present embodiment will be further described. In the following description, the sensor units 126, 128, 130, 132, and 134 are referred to as a first sensor 126, a second sensor 128, and a third sense. The detector 130, the fourth sensor 132, and the fifth sensor 134. Further, since the regions C, D, E, and F can be detected by the two sensors, they are referred to as overlapping regions, whereas the regions other than the overlapping regions (regions A, B, G, H, and I) are A sensor detects it, so it is called a normal area. Further, the overlapping area is further divided into overlapping areas C and D on the left and overlapping areas E and F on the right.

Fig. 21 is a flow chart for setting the characteristics of each region described later in the regions A to I using the first to fifth sensors 126, 128, 130, 132, and 134, and the first to fifth senses using the first to fifth senses. The detectors 126, 128, 130, 132, and 134 determine a flow chart in which areas of the areas A to I are present, and the position determination method of the person will be described below with reference to the flowcharts.

In step S1, it is first determined whether the left overlapping area is a person with a predetermined period T1 (for example, 5 seconds), and the predetermined sensor output is cleared in accordance with a predetermined condition in step S2.

Table 2 shows the determination method of the overlap region on the left side, and when the result of any of the three reaction results shown in Table 2 is matched, the outputs of the first sensor 126 and the third sensor 130 are cleared. Here, 1 is defined as having a reaction, 0 is no reaction, and 1 is 0.

In step S3, it is determined whether or not there is a person in the right overlap region by the predetermined period T1 described above, and in step S4, the predetermined sensor output is cleared according to a predetermined condition.

Table 3 shows the determination method of the overlap region on the right side, and when the result of any of the three kinds of reaction results shown in Table 3 is matched, the outputs of the second sensor 128 and the fifth sensor 134 are cleared.

Further, when any one of the six kinds of reaction results shown in Tables 2 and 3 is cut, the output of the fourth sensor 132 is also cleared, and the process proceeds to step S5. In step S5, it is determined whether or not there is a person in the normal area based on the predetermined period T1 described above, and in step S6, all of the sensor outputs are cleared.

Further, referring to Fig. 23, a case will be described in which only the outputs of the first to third sensors 126, 128, and 130 are used to determine whether or not a person is present in the areas A, B, and C.

As shown in FIG. 23, in the period T1 before the time t1, when the first to third sensors 126, 128, and 130 are all OFF (no pulse), the area A and B are determined at time t1. There is no one in C (A=0, B=0, C=0). Next, when the first sensor 126 outputs an ON signal (with a pulse wave) and the second and third sensors 128 and 130 are OFF from the time t1 to the time t2 after the period T1, the determination is made. At time t2, there is a region A and nobody at the region B, C (A = 1, B = 0, C = 0). Further, when the first and third sensors 126 and 130 output the ON signal and the second sensor 128 is OFF between the time t2 and the time t3 after the period T1, it is determined that the time C3 is the area C. Some people, areas A and B are unmanned (A=0, B=0, C=1). Hereinafter, it is determined in the same manner that each of the regions A, B, and C is a person according to each period T1.

In fact, using the first to fifth sensors 126, 128, 130, 132, 134, it is determined in the area A to I where the area is present, and Table 5 shows the use of all the sensors 126, 128, 130, Among the regions A to I of the outputs of 132 and 134, there are undetermined results.

In addition, in Table 5, the position determination other than the position determination shown in Tables 2 to 4 is performed by combining the respective determination results of steps S1, S3, and S5.

Based on the results of the determinations, each of the areas A to I is determined to be a first area (often in a place where people are often present), and a second area in which a person has a short time (a region where a person passes only and a region with a short stay time) The third area where people are in a very short time (walls, windows, etc., non-living areas where people rarely go). Hereinafter, the first region, the second region, and the third region are referred to as a living zone I, a living zone II, and a living zone III, respectively, and the living zone I, the living zone II, and the living zone III may also be referred to as zone characteristics I, respectively. Area, area characteristic II area, area characteristic III area. In addition, the life division I (region characteristic I) and the life division II (region characteristic II) are combined as a living area (a region in which people normally operate), whereas the living division III (regional characteristic III) is regarded as a non-living region ( The area where people usually do not move) can also roughly classify living areas according to the frequency of no one.

This discrimination is performed after step S7 in the flowchart of Fig. 21, and the determination method will be described with reference to Figs. 24 and 25.

Fig. 24 is a view showing the case where the indoor unit of the air conditioner of the present invention is provided in an LD in a room, a kitchen, and an LD (living room and dining room) and a kitchen, and the elliptical unit in Fig. 24 The area shown shows the place where the testee himself reports.

As described above, it is determined in each period T1 that there is no one in each of the regions A to I, and 1 (reactive) or 0 (no reaction) is output as the reaction result (determination) in the period T1, and after repeated plural times, in step S7 It is determined whether or not the predetermined air conditioner cumulative operation time has elapsed. If it is determined in step S7 that the predetermined time has not elapsed, the process returns to step S1. On the other hand, if it is determined that the predetermined time has elapsed, the reaction result accumulated to the predetermined time in each of the regions A to I is combined with two criticalities. The values are compared to determine which of the areas A to I are in each of the areas A to I.

Referring to Fig. 25 showing the long-term accumulation result, the first critical value and the second critical value smaller than the first critical value are set as follows. In step S8, it is determined whether or not the long-term accumulation result of each of the regions A to I is more than When the area is determined to be large, the first critical value is determined as the life division I in step S9. Further, if it is determined in step S8 that the long-term accumulation result of each of the regions A to I is less than the first critical value, it is determined in step S10 whether or not the long-term accumulation result of each of the regions A to I is greater than the second critical value, and it is determined that there are more The area is determined as the life division II in step S11, and the life division III is determined in step S12.

In the example of Fig. 25, the areas E, F, and I are judged as the life division I, the areas B and H are judged as the life division II, and the areas A, C, D, and G are judged as the life division III.

Further, Fig. 26 shows the case where the indoor unit of the air conditioner of the present invention is installed in the LD of another one room, one living room and one kitchen object, and Fig. 27 shows the discrimination of each area A to I based on the long-term accumulation result at this time. result. In the example of Fig. 26, the regions C, E, and G are determined as the life division I, the regions A, B, D, and H are determined as the life division II, and the regions F and I are determined as the life division III.

Further, the discrimination of the above-described regional characteristics (life distinction) is repeated for a predetermined period of time, but the determination result hardly changes as long as the sofa, the table, and the like disposed indoors are not moved.

Next, a final determination of whether or not there is a person in each of the areas A to I will be described with reference to a flowchart of Fig. 22.

Since steps S21 to S26 are the same as steps S1 to S6 of the flowchart of Fig. 21 described above, the description thereof is omitted. In step S27, it is determined whether or not a reaction result of the period T1 of the predetermined number M (for example, 15 times) is obtained. If it is determined that the period T1 has not reached the predetermined number M, the process returns to step S21, and if it is determined that the period T1 is reached. In the case of the number M, in step S28, the total of the reaction results of the period T1 × M is used as the number of cumulative reaction periods, and the number of cumulative reaction periods of one time is calculated. The number of times of the cumulative reaction period is calculated in a plurality of times, and in step S29, it is determined whether or not the calculation result of the cumulative number of reaction periods of a predetermined number of times (for example, N=4) is obtained, and if it is determined that the predetermined number of times has not been reached, the process returns to the step. On the other hand, if it is determined that the predetermined number of times has been reached, in step S30, whether or not there is a person in each of the areas A to I is estimated based on the determined area characteristic and the number of accumulated reaction periods of the predetermined number of times.

In addition, in step S31, the number of calculations (N) of the cumulative reaction period is decreased by one, and the process returns to step S21, and the number of cumulative reaction periods of a predetermined number of times is repeatedly calculated.

Table 6 shows the history of the reaction results of the latest one-time (time T1 × M). In Table 6, for example, ΣA0 means the number of cumulative reaction periods of one time in the region A.

Here, it is assumed that the number of cumulative reaction periods of the first time before ΣA0 is ΣA1, and the number of cumulative reaction periods of the previous one is ΣA2, N=4, the history of the past four times (ΣA4, ΣA3, ΣA2) In 生活A1), if there is one or more times of the cumulative reaction period of one or more times in the life division I, it is determined that there is a person. In addition, in the history of the past four times, in the history of the past four times, if the number of cumulative reaction periods of one or more times is two or more, it is determined that there is a person; and in the life division III, if the history of the past four times is more than two times, The number of cumulative reaction periods is three or more. Then it is determined that someone is there.

Next, after the elapsed time T1 × M is determined by the unmanned person, it is estimated whether or not there is a person from the history of the past four times, the life division, and the cumulative reaction period.

That is, since the indoor unit of the air conditioner of the present invention estimates whether or not a person is used using a sensor having a number smaller than the determination areas A to I, there is a possibility that the position of the person may be misjudged according to the estimation of each predetermined period. Therefore, regardless of whether or not the overlap region is used, the estimation of the position of the human body in a predetermined predetermined period is avoided, and the region characteristics of the region determination result for each predetermined period are accumulated for a long period of time, and the regions obtained by accumulating the region determination results for each predetermined period of N times are obtained. The past history of the number of times during the cumulative reaction period is used to estimate the location of the person to obtain a body position estimation result with a high accuracy.

Table 7 shows whether it is determined whether or not there is a person as described above, and when T1 = 5 seconds and M = 12 times, the required time for estimating the person and the time required for estimating the unmanned person are set.

As described above, the indoor unit of the air conditioner of the present invention divides the air-conditioned area into the plurality of areas A to I by the first to fifth sensors 126, 128, 130, 132, and 134, and then determines each area. The regional characteristics of A to I (life divisions I to III) are based on the regional characteristics of each of the regions A to I, and the estimated time required for the person is estimated, and the time required for the unmanned person is estimated.

In other words, after changing the air conditioner setting, it takes about 1 minute until the wind blows, not only changing the air conditioner setting in a short time (for example, a few seconds), but also impairing the comfort, and there will be no one in the place soon. From the point of view of energy saving, it is more appropriate to not use air conditioning. Therefore, it is first detected whether or not there is a person in each of the areas A to I, and in particular, the air conditioner in the area in which the person is located is set to be optimized.

As described in detail below, it is determined that the time required for the estimation of the area II of the life division is the standard, and the area I determined to be the life division is estimated to be shorter than the time interval determined as the area of the life division II. Here, when the area becomes unoccupied, the time interval longer than the area determined as the life division II is estimated, and no one is estimated in the area, whereby the time required for the estimation of the person is set to be short, and the unpredicted The required time is set to be shorter. On the contrary, in the area determined to be the life division III, it is estimated that the person is present at a time interval longer than the area determined to be the life division II, whereas when the area becomes unmanned, the life distinction is shorter than the discrimination. The time interval of the area is presumed to be unoccupied in the area, whereby the time required to estimate the person is set to be longer, and the time required to estimate the unmanned person is set to be shorter. Further, as described above, the life division of each region is changed by the long-term accumulation result, and accordingly, it is assumed that the time required for the person or the time required to estimate the unmanned person is also set to be changeable.

(wind direction control)

Moreover, the number of rotations of the indoor fan 8 and the wind direction control of the upper and lower blades 12 and the left and right wing plates 14 are controlled in accordance with the air conditioning settings of the respective areas A to I, and the above control will be described below.

In the greenhouse, the wind direction control system controls the wind direction to blow to the feet of the person in the area determined to be in the area of the person, so that the warm air reaches the vicinity of the foot, and the wind direction control in the cold room controls the wind direction to blow above the top of the person's head to make the cold wind Arrived at the head. The wind direction is adjusted by the angle of rotation of the indoor fan 8 with the angle of the upper and lower flaps 12 or the left and right flaps 14.

Fig. 28 shows the rotation control of the upper and lower flaps 12. When the air conditioner is stopped, as shown in (a), the front panel 4, the upper and lower flaps 12, and the left and right flaps 14 are all closed.

In the cold room, in order to allow the blown air (cold air) to reach the top of the person's head (the cold room ceiling airflow), the state shown in (b) is passed from the state shown in (a) to the state shown in (c). First, the control arm portions 118, 120 are driven to move the front panel 4 away from the front suction port 2a, and the control arm portions 122, 124 are driven to move the upper and lower flaps 12 away from the air outlet 10.

In the state of (c), the air blown out by the air outlet 10 is guided to the horizontal direction by the upper and lower flaps 12, and the air flow is sent to the room since the lower end side of the upper and lower flaps 12 is bent upward. The distance. At this time, the upper side of the air outlet 10, that is, the lower side of the front panel 4 is closed by the middle wing 114, and a part of the air blown by the air outlet 10 is not guided to the front suction port 2a.

On the other hand, in the case of a warm room, in order to allow the blown air (warm air) to reach the person's foot (the airflow at the foot of the warm room), the state shown in (a) passes through the state shown in (b) and reaches (d). State. In the state of (d), the air blown out by the air outlet 10 is guided obliquely downward by the upper and lower flaps 12, but since the lower end side of the upper and lower flaps 12 is bent toward the main body side, it is easy to be stagnated above the room. Warm air is delivered to the bottom of the room.

In addition, (e) is used in the cold room before the stability, and the blown air is blown to the human body (blowing to the human body airflow).

Fig. 29 shows the number of rotations of the indoor fan 8 when air conditioning in each of the areas A to I is performed, and A1, A2, and A3 are the reference rotation numbers of the indoor unit in the close range, the medium distance, and the long distance, and A4 is The difference in the number of rotations due to the difference in the area at the same time is set, for example, as follows.

A1: 800 rpm (in warm room), 700 rpm (in cold room)

A2: 1000 rpm (in warm room), 900 rpm (in cold room)

A3: 1200 rpm (in warm room), 1100 rpm (in cold room)

A4: 100 rpm (cool and warm common)

Here, the expression called the relative position is introduced, and the positional relationship with the indoor unit, such as the distance with respect to the indoor unit, the angle with respect to the front surface of the indoor unit, and the height difference, in each area is shown.

In addition, the ratio of the degree of air conditioning required is indicative of the fact that air conditioning is easy to be performed in each area, and it is difficult to perform air conditioning. The higher the air conditioning requirement is, the more difficult it is to perform air conditioning, and the lower the air conditioning requirement, the easier the air conditioning is. For example, the farther away from the indoor unit, the harder it is to reach the air that is blown out, and it is difficult to perform air conditioning, so the air conditioning requirement is higher. That is, there is a close relationship between the degree of air conditioning requirements and the relative position with respect to the indoor unit. In the present embodiment, the air conditioning requirement is specified in relation to the relative position of the indoor unit.

Therefore, when the number of set rotations of the indoor fan 8 in the air conditioning of each of the areas A to I is higher, the setting is higher. That is, the farther the position of the area in which the air conditioner is to be performed is from the indoor unit, the set number of rotations of the indoor fan 8 is set higher, and when the distance to the indoor unit is the same, the front side of the indoor unit is biased toward the left and right. In the side area, the set number of rotations of the indoor fan 8 is set higher. When the area to be air-conditioned is one, the set number of rotations (air volume) in the area is set, and when the area to be air-conditioned is plural, the number of set rotations in the area where the air-conditioning requirement is high is set.

Further, Fig. 30 shows the set angles of the upper and lower flaps 12 and the left and right flaps 14 in the warm room, and B1, B2, and B3 are the reference upper and lower flap angles of the regions of the close, middle, and long distances with respect to the indoor unit. On the other hand, when B4 is the same distance, the angle difference between the upper and lower blades is different depending on the area. On the other hand, the left and right wing angles of the left and right areas of C1 and C2 are (turned to the left to the positive direction), and C3 and C4 are The angular difference between the right and left flaps 14 due to the difference in the area is set, for example, as follows. In addition, the angle of the upper and lower flaps 12 refers to a state in which the line connecting the front end and the rear end of the wing is horizontal when the wing portion is convex upward, and the position is measured counterclockwise as the reference. angle.

B1: 70°

B2: 55°

B3: 45°

B4: 10°

C1: 0°

C2: 15°

C3: 30°

C4: 45°

That is, when the warm room in the area A or B of the indoor unit is approached, the upper and lower flaps 12 are set to the first angle (for example, 70°), and the number of rotations of the indoor fan 8 is set to the first number of rotations (for example, 800 rpm). Control the wind direction to the edge of the indoor unit side of the area A or B (the foot of the person) so that the warm air reaches the foot. Further, when a greenhouse in a region C, D, E or F which is a medium distance from the indoor unit is performed, the upper and lower blades 12 are set to be smaller than the second angle (for example, 55°) of the first angle, and the indoor fan 8 is set. The number of rotations is set to be higher than the second rotation number of the first rotation number (for example, 1000 rpm), and the wind direction is controlled to be the edge portion of the indoor unit side (the foot of the person) in the region C, D, E or F, so that the warm air is provided. Arrived at the foot. Further, when the warm room of the area G, H or I farthest from the indoor unit is performed, the upper and lower flaps 12 are set to be smaller than the third angle (for example, 45°) of the second angle, and the number of rotations of the indoor fan 8 is set. The third rotation number (for example, 1200 rpm) is set to be higher than the second rotation number, and the wind direction is controlled to be the edge portion (the foot of the person) on the indoor unit side of the region G, H, or I so that the warm air reaches the foot.

Fig. 31 shows the set angles of the upper and lower flaps 12 and the left and right flaps 14 when starting the operation or the cold room in the unstable area, and E1, E2, and E3 are the areas of the close, middle, and long distances with respect to the indoor unit, respectively. The reference vertical wing angle, E4 is the angular difference between the upper and lower blades caused by the different regions when the distance is the same. In contrast, F1 and F2 are the left and right wing angles of the left and right regions (turning to the left to the positive direction). F3 and F4 are angle differences of the left and right flaps 14 which are generated depending on the area, and are set, for example, as follows. In addition, the start operation refers to a state in which the operation of the air conditioner starts, and the unsafe zone refers to a state in which the current indoor air conditioner state has not yet become a set condition (for example, a set temperature).

E1: 50°

E2: 35°

E3: 25°

E4: 10°

F1: 0°

F2: 15°

F3: 25°

F4: 35°

Further, Fig. 32 shows the set angles of the upper and lower flaps 12 and the left and right flaps 14 in the cold room in the stable area, H1 is the reference upper and lower flap angle at the time of the ceiling airflow, and H2 is the reference upper and lower flap angle when the airflow is released, and H3 is the angular difference between the upper and lower blades due to the difference in distance. In contrast, I1 and I2 are the left and right wing angles of the left and right areas (turning to the left in the positive direction), and I3 and I4 are generated depending on the area. The angular difference between the left and right flaps 14 is set, for example, as follows. In addition, the stability zone refers to the state in which the current indoor air conditioning state is already set (for example, the set temperature).

H1:180°

H2: 190°

H3: 5°

I1: 0°

I2: 15°

I3: 25°

I4: 35°

Here, as shown in Fig. 28(c), the ceiling airflow is such that the upper and lower blades 12 are located below the air outlet 10, and the airflow when the air is blown out by the concave surface of the wing is released, and the airflow is released. The upper and lower flaps 12 are slightly located at the upper portion when the airflow is higher than the ceiling airflow, so that a part (minor amount) of the blown wind can flow to the convex side of the wing (below the wing), making it difficult for the wing to be convex. The airflow in the state where the wind is generated in the state of condensation.

When the cold room of the area A or B near the indoor unit is performed, the upper and lower flaps 12 are set to a predetermined angle (for example, 5°) below the horizontal level, and the number of rotations of the indoor fan 8 is set to the first number of rotations (less than The number of rotations of the first rotation number in the warm room, for example, 700 rpm, is set such that the cold air reaches the top of the head of the area A or B so that the cold air can fall like the water flowing out of the shower head at the time of showering. Moreover, when the cold room of the area C, D, E or F with respect to the indoor unit is performed, the upper and lower flaps 12 are set to be slightly horizontal, and the number of rotations of the indoor fan 8 is set higher than the first rotation. The number of the second rotations (less than the number of rotations of the second rotation number in the case of the greenhouse, for example, 900 rpm) is set such that the cold air can reach the top of the head in the region C, D, E or F. Further, when the cold room of the area G, H or I farthest from the indoor unit is performed, the upper and lower flaps 12 are set to be slightly above the horizontal by a predetermined angle (for example, 5°), and the number of rotations of the indoor fan 8 is set to The third rotation number higher than the second rotation number (less than the number of rotations of the third rotation number in the warm room, for example, 1100 rpm) is set such that the cold air can reach the top of the head in the region G, H or I.

Next, the wind direction control performed in accordance with the number of areas in which the air conditioner is to be performed will be described with reference to the flowchart of Fig. 33.

After the operation of the air conditioner starts, in step S41, it is first determined that there is no one in the areas A to I, and in step S42, it is determined that the area where the person is present is one, that is, when the area to be air-conditioned is one, In step S43, air conditioning is performed according to the air volume and the wind direction set in the area. When it is determined in step S42 that the area to be air-conditioned is not one, it is determined in step S44 whether or not the area to be air-conditioned is two, and when the area to be air-conditioned is two, the operation proceeds to step S45.

In step S45, the air volume is set to the set air volume in the area where the air conditioning requirement is high, and the arrangement mode of the two areas is identified as the five modes as shown in FIGS. 34A to 34E, in the next step S46. In accordance with the mode identified, it is controlled as shown in Table 8.

Here, mode 1 is a case where two areas are adjacent to each other with a medium distance and a front side of the indoor unit, and mode 2 indicates a case where two areas adjacent to each other are substantially coincident with the angle of the indoor unit, and the mode is also 3 represents the case where the angle is substantially the same as that of the indoor unit, and the two areas are separated by the context, and the mode 4 represents the case where the distance between the indoor unit and the indoor unit is substantially the same, and the mode 5 represents the two between the two. The area, in other words, the two areas with different distances and angles from the indoor unit.

Above the mode 1 to 4, the downwind direction is fixed to the area where the demand is low in the case of the warm room, and the area where the demand is high is fixed in the case of the cold room. Further, in the mode 5, the downwind direction controls the operation of the upper and lower flaps 12, and in the two regions (the first and second regions), the wind direction is changed to the second region after staying in the first region (the angle is fixed) for a predetermined time. After the predetermined time has elapsed in the second area, the wind direction is changed to the first area, and this operation is repeated. Further, the residence time of each zone can be set separately according to, for example, the distance from the indoor unit, and the longer the stay time from the indoor unit is, the longer.

Further, the left and right wind directions of the mode 1 are fixed to the center of the adjacent two regions, and in the case of the modes 2 and 3, the two regions can be regarded as two regions located at different distances but slightly in the same direction from the indoor unit. The left and right direction is fixed to the area where the degree of demand is high. Further, the mode 4 and the left and right wind direction of the mode 5 composed of the two separated regions are controlled in the same manner as the upper and lower blades 12, and the operation of the left and right flaps 14 is controlled to change the wind direction to the first time after staying in the first region for a predetermined period of time. In the 2 area, after the predetermined time has elapsed in the 2nd area, the wind direction is changed to the 1st area, and this action is repeated. Further, the dwell time of each region can be set corresponding to the relative position of each region with respect to the indoor unit, for example, with respect to the angle of the front surface of the indoor unit, and the longer the dwell time with respect to the angle of the front surface of the indoor unit is preferably longer.

Moreover, when it is determined in step S44 that there are two areas in which the air conditioner is to be performed, in step S47, it is determined in the two modes of the normal mode or the special mode that three or more areas of the air conditioner are to be arranged in accordance with the arrangement. Here, the special mode is a case where two areas adjacent to each other across the front surface of the indoor unit and a long area and one area on the front side of the indoor unit are combined into three areas; three of the above cases are removed. The situation in the above area is shown as the normal mode. When the area to be air-conditioned is three or more, the air volume is set to the set air volume in the area where the air conditioning request degree is the highest, and when it is determined in step S47 that the special mode shown in FIG. 35A (center adjacent), the wind direction is performed in step S48. Set to the same as mode 1 of Figure 34A.

On the other hand, when it is determined in step S47 that the mode is not special, the normal mode control shown in Fig. 35B or Fig. 35C is performed in step S49, and the up and down wind direction is set at an angle and a distance from the upper and lower flaps 12 in the region closest to the indoor unit. The angle between the upper and lower blades 12 is changed between the set angles of the upper and lower blades 12 in the farthest area of the indoor unit.

Further, in the normal mode, the left and right wind directions set the angles of the left and right flaps 14 of the both ends (the regions C and I in Fig. 35B and the regions C and H in Fig. 35C) to the left end angle and the right end angle. After the left end angle stays for a predetermined time, the wind direction is changed to the area on the right end side (sliding), and after the right end angle stays for a predetermined time, the wind direction is changed to the area on the left end side, and the action is repeated (sliding). Further, the operating speed of the left and right flaps 14 at the time of sliding is set to be slower than the operating speed of the left and right flaps 14 of the above modes 4 and 5. Further, the staying time of the left end angle or the right end angle may be set in accordance with, for example, an angle with respect to the front surface of the indoor unit, and the larger the angle with respect to the front surface of the indoor unit, the longer the staying time is.

Further, after the respective air conditioning control is performed in steps S43, S46, S48 or S49, the process returns to step S41.

(Skin care and house control)

Here, a method of using the wind direction control of the human body detecting device (the sensor unit 126, 128, 130, 132, 134) described so far and the electrostatic atomizing devices 18, 18A in combination to more effectively utilize the electrostatic mist will be described. As described above, in addition to the deodorizing effect of removing the odor component, the electrostatic mist has an effect of improving the skin texture. The effect of improving the skin quality is that if the electrostatic mist reaches the skin of the occupant, there is a personal difference, but it can bring moisturizing effect to the human skin.

In the present embodiment, the control whose main purpose is to improve the human skin when the electrostatic mist is generated is called the skin care mode, and the control for the purpose of generating the electrostatic mist when no one is present to exert the indoor deodorizing effect is called For the house protection mode. In addition, when the electrostatic mist generated by the skin care mode reacts with the odor component in the room, the deodorizing effect can also be exhibited.

The air conditioner of the present embodiment has a human body detecting device (sensor unit 126, 128, 130, 132, 134) as a human body detecting device, and can detect an unmanned human body detecting sensor, and can generate electrostatic fog. The indoor unit of the devices 18 and 18A is provided with a skin care mode in which a person is present in the room and a house mode in which no one is present. That is, when it is determined that there is a person in the predetermined area within the detection range of the human body detecting sensor, the skin care mode is set, and the wind direction is controlled to be the predetermined area, so that the electrostatic mist reaches the detected person or the predetermined area; When it is determined that no one is within the detection range of the human body detecting sensor, the house mode is set so that the static fog reaches the upper or far side. In addition, the wind direction control described above is controlled in conjunction with the indoor temperature during the warm room and the cold room or the temperature felt by the human body located indoors, but it can also be combined with the operation of the cold and warm room to generate electrostatic fog, or it can also be combined with stopping the freezing. The circulating air supply operates to generate an electrostatic mist.

According to the above configuration, in the skin care mode, the skin can be moisturized by the electrostatic mist. Moreover, in the house mode, since no one is present, it is not necessary to consider that the blown airflow is not blown to the person, and the odor component adhering to the wall, the curtain, etc. can be efficiently and effectively removed from the ceiling above or the entire room. Or sterilizing to achieve a comfortable indoor environment.

The following describes a method of carefully detecting the direction or region in which a person is present by the human body detecting sensor, and finely controlling the method.

In the skin care mode performed by some people, the rotation number control of the indoor fan 8 and the wind direction control of the upper and lower wing plates 12 and the left and right wing plates 14 are controlled in the same manner as the above-described wind direction control in response to the air conditioning settings of the respective areas A to I. At this time, the wind direction is controlled to blow to the feet of the person who is determined to be in the area where the person is located, and the wind direction is controlled so that the blown air (cold air) is blown to the cold room and is determined to be above the area where the person is. At the same time, the electrostatic atomizing devices 18 and 18A are operated to cause the electrostatic mist generated by the electrostatic atomizing devices 18 and 18A to reach the occupant together with the warm air or the cold air to perform skin care.

Further, in the skin care mode, the number of rotations of the indoor fan 8 and the wind direction control of the upper and lower flaps 12 and the left and right flaps 14 may be controlled without controlling the wind direction to determine the area of the person, so that the electrostatic mist reaches a relatively frequent presence. Area (area of area characteristic I).

On the other hand, in the refuge mode that no one is in, the indoor fan 8 and the electrostatic atomizing devices 18 and 18A are operated to remove the odor components adhering to the wall surface, the curtain, the floor, or the ceiling. As shown in Figures 29 and 32, the upper and lower wing plates 12 and the left and right wing plates 14 are controlled, and the ceiling airflow performed in the cold room is in the order of areas A, B, C, F, G, H, and I, so that the electrostatic mist reaches the same. Regional scheduled time.

The areas A, B, C, F, G, H, and I are located outside in the nine divided areas and are far from the indoor unit, and it is presumed that there are walls or curtains in the areas. Moreover, by using the ceiling airflow blown to the upper side, the electrostatic mist can reach the ceiling where smoke or the like may adhere, and the electrostatic mist flowing along the ceiling by the ceiling airflow hits the wall surface and flows downward, so Deodorization and sterilization of the floor can be performed.

Here, since the areas A and B are located in the vicinity of the indoor unit installation surface (wall surface), the ceiling airflow may not sufficiently perform the deodorization and sterilization of the places. Therefore, the wind direction control can be performed by setting the angles of the upper and lower wing plates 12 and the left and right wing plates 14 as shown in Fig. 36 instead of the wind direction control of Fig. 32.

Next, the indoor fan 8 and the upper and lower blades 12 and the left and right wing plates 14 are controlled in consideration of the above-described regional characteristics I, II, and III. That is, the region of the regional characteristic I is a region where the frequency is high, and the frequency of the person is lower in the order of I→II→III. Therefore, the indoor fan 8 and the upper and lower wing plates 12 and the left and right wing plates 14 are controlled from a high frequency region, and the electrostatic mist reaches the region in the order of the regional characteristics I to III for a predetermined time. Further, in a region where the probability is high, since the possibility of adhesion of odor is also high, the predetermined time for the electrostatic mist to reach can be increased in the order of the region characteristic III→II→I. By performing the wind direction control as described above, it is possible to remove even if an odor is attached.

On the contrary, in some areas where the frequency is high, in the skin care mode that someone is doing at the time, sufficient electrostatic fog may have been supplied. Therefore, it is also possible to control the room from the lower frequency area in order. The fan 8 and the upper and lower flaps 12 and the left and right flaps 14 cause the electrostatic mist to sequentially reach the regions of the region characteristics I to III for a predetermined period of time. Further, since some people may be in a low frequency region, the skin may not be sufficiently deodorized in the skin care mode. Therefore, the predetermined time for the electrostatic mist to reach the regions may be increased in accordance with the order of the regional characteristics I→II→III. By controlling the wind direction as described above, even the taste remaining without being sufficiently removed can be removed.

Alternatively, an accumulating means may be provided to calculate the time at which the electrostatic mist is reached due to the accumulated time calculated by the accumulating means in the skin care mode. That is, the longer the accumulation time, the more the residual odor is, so in the housekeeping mode, the predetermined time at which the electrostatic mist arrives is increased, whereby the deodorizing effect or the sterilizing effect can be further enhanced.

Further, in the example of Fig. 29, the maximum number of rotations of the indoor fan 8 at the time of air conditioning is 1200 rpm. However, since no one has no need to consider noise or the like at all, the number of rotations of the indoor fan 8 is added to the wind direction changing mechanism. The air resistance of the upper and lower wing plates 12 and the left and right wing plates 14 is set as shown in Fig. 37, and the reachability of the electrostatic mist can be improved.

L1:1200rpm

L2: 1300 rpm

L3: 1400 rpm

At this time, the ventilation fan unit 16 is further operated to release the indoor air to the outside to promote the purification of the indoor air.

In addition, when any one of the first to fifth sensors 126, 128, 130, 132, 134 detects the entry of a person in the middle of the skin care and the house control, the air conditioning setting of the detected area is determined. In response to the above-mentioned "management control", the above-described number of rotations of the indoor fan 8 and the wind direction control of the upper and lower blades 12 and the left and right wing plates 14 are performed.

Further, when the person leaves, the operation of the air conditioner can be classified into a temporary situation or a situation in which the person stops the air conditioner and leaves. In the case of temporarily leaving during operation, the housekeeping mode can be directly started in the operation of the heating and cooling room in response to the lengthening of the time of no one, and the housekeeping mode can be performed in the energy-saving operation described later. When the person leaves without being in the room, the air supply operation can be performed for a predetermined time, and then the house mode is performed.

(Detecting unattended energy-saving control and preventing forgetting shutdown control)

A timer is provided in the indoor unit, and the timer is used to detect the unmanned energy-saving control and prevent forgetting the shutdown control. The following describes the method of performing the housekeeping mode under the aforementioned detection of unmanned energy saving control and prevention of forgetting shutdown control.

Fig. 38 shows an example in which the power saving operation is achieved by controlling the air volume (rotation number) of the indoor fan 8 and the compressor capacity provided in the outdoor unit when the person is not indoors.

That is, since the heat exchange efficiency of the heat exchanger 6 is increased when the air volume of the indoor fan 8 is increased, when the frequency of the compressor is the same, the capacity of the cold room or the greenhouse is increased, so that the indoor temperature is kept the same. The set temperature reduces the frequency of the compressor and reduces the required power consumption. Further, even when no one is present, even if the air volume of the indoor fan 8 is increased, there is no problem that the airflow is too strong, or the comfort of the indoor fan 8 is increased. Further, at this time, by blowing out at the same time, the electrostatic mist can be blown to the corners of the room, and can be used as a housekeeping mode for deodorization and sterilization.

As shown in FIG. 38, when the first to fifth sensors 126, 128, 130, 132, and 134 detect that none of the areas A to I are at (t0), the timer starts counting, and the timer is started. After the start of the timer, if no one is present at time t1 (for example, 10 minutes), the air volume of the indoor fan 8 is increased, and the frequency of the compressor is reduced stepwise until time t2 (for example, 30 minutes after the start of the timer). After the time t1 elapses, the air volume of the indoor fan 8 is kept constant (limit value). After the time t2 elapses, the frequency of the compressor is kept constant (limit value), and at time t2 and time t3 (for example, 1 hour after the start of the time) At time t4 (for example, 2 hours after the start of the time counting) and time t5 (for example, 4 hours after the start of the counting), if it is continuously confirmed that no one is present, the operation of the air conditioner is stopped at time t5 to prevent forgetting to turn off the air conditioner.

Further, between time t1 and time t5, if a person is detected, the set air volume and the set frequency before time t1 are restored.

Next, a method of changing the indoor set temperature to the target temperature in response to the elapsed time will be described. First, the control at the time of the warm room will be described with reference to Tables 9 and 39.

Fig. 39 shows an example of temperature adjustment. Here, the case where the set temperature T set is set to 28 ° C and the target temperature (limit value) is 20 ° C will be described. In addition, ΔT sets the temperature difference between the temperature T set and the target temperature. That is, the target temperature is a threshold value at which the function of the greenhouse is lowered when no one is at the time of energy saving.

When it is detected by the first to fifth sensors 126, 128, 130, 132, 134 that none of the regions A to I are present, the timer starts counting, after the timer starts counting, at time t1 (for example 10 minutes) If no one is confirmed, the set temperature T set is automatically lowered by 2 ° C (1/4 ΔT). Then, when it is confirmed that there is no one at time t2 (for example, 30 minutes after the start of the counting), the set temperature T set is automatically lowered by 2 ° C (1/4 ΔT). Hereinafter, in the same manner, when it is confirmed that there is no one at time t3 (for example, one hour after the start of counting) and time t4 (for example, two hours after the start of counting), the set temperature T set is automatically lowered by 2 ° C (1/4 ΔT). As described above, as the greenhouse temperature is lowered by automatically lowering the set temperature Tset, the frequency of the compressor can also be lowered. For example, it is also possible to proceed to the lowering step of time t2 to extend it to successively decrease until t5.

At time t4, since the total temperature T set is lowered by 8 ° C and is equal to the target temperature of 20 ° C, the set temperature T set is maintained at the target temperature until time t5 (for example, 4 hours after the start of the counting), but even at time t5. It is also confirmed that when no one is present, the operation of the air conditioner is stopped, and the air conditioner can be prevented from being forgotten. In this way, energy saving control can be performed by detecting no one, and unnecessary power supply operation can be prevented to reduce power consumption. Further, at this time, the amount of air is increased and an electrostatic mist is generated and blown at the same time, so that the electrostatic mist can be blown everywhere, and can be deodorized and sterilized as a housekeeping mode.

Further, if a person is detected between time t1 and time t5, the set temperature T set before time t1 is returned.

Further, as shown in Table 9, the temperature adjustment range (reduced temperature) is set in accordance with the temperature difference ΔT between the set temperature T set and the target temperature, and the smaller the temperature difference ΔT is, the smaller the temperature adjustment range is. Further, when the set temperature Tset is lower than the target temperature, the current temperature is maintained. However, when it is confirmed that there is no one at time t5, the operation of stopping the air conditioner operation is the same as that of the example of Fig. 39.

Next, the control at the time of cold room will be described with reference to Table 10 and FIG.

Fig. 40 shows an example of temperature adjustment. Here, the case where the set temperature T set is set to 20 ° C and the target temperature (limit value) is 28 ° C will be described. In addition, ΔT sets the temperature difference between the temperature T set and the target temperature.

When it is detected by the first to fifth sensors 126, 128, 130, 132, 134 that none of the regions A to I are present, the timer starts counting, after the timer starts counting, at time t1 (for example 10 minutes) If no one is present, the set temperature T set is automatically increased by 2 ° C (1/4 ΔT). Then, when it is confirmed that there is no one at time t2 (for example, 30 minutes after the start of the counting), the set temperature T set is automatically increased by 2 ° C (1/4 ΔT). Hereinafter, in the same manner, when it is confirmed that there is no one at time t3 (for example, one hour after the start of counting) and time t4 (for example, two hours after the start of counting), the set temperature T set is automatically increased by 2 ° C (1/4 ΔT).

At time t4, since the total temperature is 8 ° C from the set temperature T set and is equal to the target temperature of 28 ° C, the set temperature T set is maintained at the target temperature until time t5 (for example, 4 hours after the start of the counting), but even at the time. T5 is still confirmed as no one is at the time, that is, the operation of the air conditioner is stopped, and the air conditioner can be prevented from being forgotten. In this way, energy-saving control can be performed by detecting no one to prevent unnecessary cold room operation and reduce power consumption. Further, at this time, the amount of air is increased and an electrostatic mist is generated and blown at the same time, so that the electrostatic mist can be blown everywhere, and can be deodorized and sterilized as a housekeeping mode.

Further, if a person is detected between time t1 and time t5, the set temperature T set before time t1 is returned.

Further, as shown in Table 10, the temperature adjustment range (elevated temperature) is set in accordance with the temperature difference ΔT between the set temperature T set and the target temperature, and the smaller the temperature difference ΔT is, the smaller the temperature adjustment range is. Further, when the set temperature Tset is higher than the target temperature, the current temperature is maintained. However, when it is confirmed that no one is present at time t5, the operation of stopping the air conditioner operation is the same as that of the example of Fig. 40.

Further, in any of the above-described examples of Figs. 38 to 40, in the normal operation, when the predetermined time is not present, the power-saving operator who consumes less power than the normal operation is performed, and after that, the predetermined time is not passed. When the person is present, the operation of the air conditioner is stopped to achieve energy saving ("normal operation" means "operation indicated by the user").

In addition, there is a possibility that an external force other than a person who is not in the room for a long time, but the person who is likely to cause a temperature change affects the detection of the sensor by the human body, and causes the normal operation to be maintained in the absence (unmanned) state. It is generated, so that the operation is stopped when the time t6 (for example, 24 hours) longer than the time t5 is passed, whereby the forgetting of the shutdown can be surely prevented. Further, before the operation is stopped after the time t5 or the time t6 longer than the time t5, it is preferable to perform an audible or visual notification on the main body or the remote controller with a sound or an LED lamp, or to display a character on the screen. Further, if the automatic stop selection mechanism for automatically stopping the operation after the time t5 or the time t6 longer than the time t5 is selected in the remote controller or the like, it is more convenient to use.
