Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an air conditioner, and more specifically, an air conditioner equipped with a wind direction plate that can freely adjust the blowing direction and wind speed of cooled or heated air. It is related to air conditioners.

[Prior art] -Therefore, the conventional air conditioner is one
As shown in Japanese Patent No. 6359, a wind direction plate is provided which can selectively switch the direction of air blowing between a substantially horizontal direction and a vertically downward direction. During cooling, cold air is blown out in a substantially horizontal direction, and during heating, it is blown out vertically downward, making the circulation of cold or warm air more effective within the room.

[Problems to be Solved by the Invention] In the conventional air conditioners described above, the noise increases as the wind speed increases, so the noise is generally kept low. Therefore, during heating, the blowing speed of warm air is slow, so it rises before it reaches the floor.

Warm air does not shine directly onto the floor, and it takes a considerable amount of time for the floor to warm up. In order to solve this problem, it is conceivable to keep the length Lp of the second air outlet constant and reduce the WD in Fig. 5 to narrow the area of the air outlet and increase the wind speed. When the speed is increased, not only does the noise increase at an accelerated pace, but also the cold air from the surrounding area is easily drawn in, causing another problem: the temperature of the warm air reaching the floor drops significantly, making it impossible to provide soft or gentle heating. .

Therefore, one object of the present invention is to provide an air conditioner that can quickly start up during cooling and heating, and can also perform gentle cooling and heating.

[Means for Solving the Problems] In the present invention, in order to achieve the above object, a wind direction plate is provided at the opening of the air conditioner main body, similar to the conventional one. However, its structure is different from that of the conventional one, and it is composed of a main wind direction plate and an outer wind direction plate provided to surround the main wind direction plate, and these wind direction plates are rotated integrally in a predetermined direction. Further, when rotating in another direction, only the main wind direction plate is configured to be rotated when a predetermined position is reached. Thus, in the invention set forth in claim 1, a wind direction plate is provided in an opening of an air conditioner main body so as to be rotatable about a substantially horizontal axis, and the wind direction plate has a relatively small area. and an outer wind direction plate that surrounds at least a part of the outer periphery of the main wind direction plate, and the outer periphery is selected to have a size that substantially closes the opening when in a predetermined position. , the main wind direction plate and the outer wind direction plate are connected to each other via a splinter, and when the main wind direction plate is rotated in a predetermined direction and reaches a predetermined position, the outer wind direction plate hits the locking body, and the outer wind direction plate hits the locking body. The frontage is now blocked, and the main wind direction plate is released and separated from the outer wind direction plate and further rotated, so that the main wind direction plate portion becomes the air outlet, and when integrated, the 08 port becomes the air outlet. It is configured as follows.

[For production] Since the present invention is configured as described above.

Now rotate the wind direction plate in one direction (clockwise in the example shown),
When reaching the predetermined position, the outer envelope wind direction plate hits the locking body and the outer envelope wind direction plate stops. In this position, the outer wind direction plate closes the opening of the air conditioner main body. Therefore, air is mainly blown out only from the main wind direction plate. Therefore, by adjusting the amount of rotation of the main wind direction plate to determine the blowing direction, cold air or warm air is blown out in the desired direction. At this time, since the opening is narrowed by the outer wind direction plate, the wind speed is high, and therefore, for example, during heating, warm air can be blown close to the floor surface, allowing heating to start up quickly. In addition, the length Ω and width W of the main wind direction plate are determined by the area A determined by the required blowing wind speed.
It is clear that by keeping (QXv) constant and making αXW as small as possible, the cooling effect can be increased.It is clear that cooling can be similarly achieved with a quick start-up.

Furthermore, when the main wind direction plate is rotated in the opposite direction (counterclockwise in the illustrated example), the outer wind direction plate is connected to the main wind direction plate via a spring, so the outer wind direction plate will eventually rotate as a unit. move. In other words, the opening of the air conditioner main body is fully opened6.Therefore, by rotating the air conditioner by an appropriate amount, air can be blown out from the entire opening in a predetermined direction.

At this time, since the blowout area is large, the wind speed is low and gentle cooling and heating can be achieved.

As described above, according to one aspect of the present invention, not only can the direction of the air bath be adjusted by simply rotating the main wind direction plate, but also the wind speed can be changed without controlling the rotational speed of the fan. Therefore, cooling and heating can be done quickly, and
It can also provide gentle or soft cooling and heating. Moreover, it has the advantage that it has a simple structure and can be provided at a low cost.Since the structure is simple, it is possible to provide an air conditioner that has few breakdowns and is easy to maintain and inspect.

Moreover, the invention stated in the second claim is:
Since the main wind direction plate is driven by a motor,
Remote control is possible. Therefore, the air conditioner can be installed at a relatively high position in the room, and there is an advantage that the room can be used more widely. Furthermore, the motor can be controlled by a microcomputer, improving operability.

[Embodiment] When implementing the present invention, it is desirable that the main wind direction plate is driven by a motor and controlled by a microcomputer. This is because by storing the motor pulses in the memory section of the microcomputer, the wind direction plate can be returned to its original position. This is also because remote control is possible by controlling it with a microcomputer.

In addition, it is desirable that the outer wind direction plate be installed so as to surround the main wind direction plate symmetrically6.If it is installed symmetrically, there will be less turbulence in the air flow, pressure loss will be prevented, and noise will be suppressed. Moreover, the aesthetic effect of the outside 1j is also great.

Note that in carrying out the present invention, the air conditioner main body includes the following:
A heat pump type cooling/heating device or a heater for space heating is installed as appropriate.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Now, referring to FIG. 1, a substantially rectangular opening 10 is formed at the lower front of the air conditioner main body 1, and a main wind direction plate 2 and an outer wind direction plate 3 are provided to close this opening. It will be understood that what is being said.

The main wind direction plate 2 and the outer wind direction plate 3, which constitute the wind direction plate, are both rotatable. Therefore, when the main wind direction plate 2 is rotated clockwise with the outer wind direction plate 3 in the closed position to blow air only from the main wind direction plate, the length rQJ
is smaller than that of the outer wind direction plate 8, rLJ, so the blowout area is small, and when the outer wind direction plate 3 and the main wind direction plate 2 are integrated and rotated counterclockwise to blow out from all openings, the area is It's going to get bigger. A configuration example for this will be explained with reference to FIG. 6.7.8 which schematically shows it. 6th
As shown in the figure, the main wind direction plate 2 has a substantially cylindrical shape. That is, the pair of front and rear plates 20.21 and the pair of side plates 22.23 form a cylinder with a horizontally long rectangular cross section, and air passes through the hollow part of the cylinder as shown by arrow A. It has become. Further, shafts 24.degree. 25 are integrally provided on the side plates 22, 23, and by driving this shaft, the main wind direction plate 2 can be rotated around its axis.

The outer wind direction plate 3, which is formed in a shape to surround the main wind direction plate 2, has a substantially U-shape, as shown in FIG. 6, and the main wind direction plate 2 is housed inside it. ing.

The length "L" and the width rWJ of the outer wind direction plate 3 are approximately the same as those of the opening 10 of the air conditioner main body 1, and have air passages 31.degree. 32 on both sides. Also, through holes 33 and 34 are formed in these air passages 31 and 32, into which the shafts 24 and 25 of the main wind direction plate 2 are inserted.

As similarly shown schematically in FIG. It is pivoted on. The main wind direction plate 2 and the outer wind direction plate 3 are connected by a spring 5. Therefore, axis 2
When 4 is rotated, the main wind direction plate and the outer wind direction plate are rotated as one unit.

FIG. 7 is a schematic diagram of the air conditioner main body 1 viewed from the front, and in this state, the opening 10 is substantially blocked by the main wind direction plate 2 and the outer wind direction plate 3. In this state, a locking body 35 is attached to a part of the outer wind direction plate 3 as shown in FIG.
For example, it is in contact with a part of the casing. therefore,
When the main wind direction plate 2 is rotated clockwise as shown in FIG. 8(B), the main wind direction plate 2 is separated from the outer wind direction plate 3 and assumes the position shown in (B). In this state, most of the opening 10 is blocked by the outer wind direction plate, and air is mainly blown out only from the main wind direction plate 2. Therefore, the wind speed is high and reaches far. Therefore, this state will be referred to as the "start-up time" of cooling/heating. On the contrary, when the main wind direction plate 2 is rotated in one counterclockwise direction as shown in FIG. 8(c), the outer wind direction plate 3 is also rotated together. In this state, the opening 10 is fully opened and the wind speed is slow, allowing for gentle cooling and heating. It rotates further and air is blown out substantially downward. The state shown in (d) in Figure 8 is "normal heating"
I will call it.

6 to 8 are schematic diagrams for convenience of explanation, and figures corresponding to these schematic diagrams are shown in FIG. 3.4.5. That is, Fig. 3 shows a state in which the outer wind direction plate 3 is separated from the main wind direction plate 2 and is rotated so that it is within a range of 30 to 35'' from the vertical direction. It reaches close to the surface, so it is at the "startup time". Further, FIG. 4 shows a state in which the outer wind direction plate 3 is integrated with the main wind direction plate 2, the opening 10 is opened, and air is blown out in a substantially horizontal direction, indicating "cooling". In FIG. 5, the air is similarly separated and blown out substantially downward, so it shows the "normal heating" state.

In addition, the reference numeral 4 in FIGS. 2 and 3 indicates a motor for driving the main wind direction plate 2, and the reference numeral 6 indicates an indoor fan.

This embodiment is configured as one or more.

It has various effects compared to conventional ones. That is, the ninth
The figure is a side view of the hot air blowing temperature of a conventional air conditioner with a low wind speed during heating operation. Although the temperature reaches only 0.5 to 0.55m above the surface, in this example, in the state of ``at startup'', the temperature distribution of 30°C reaches the floor surface and reaches 35°C, as shown in Figure 10. The temperature distribution reaches 0.1 to 0.15 rn above the floor surface. In other words, the floor is heated directly.

Also, when comparing the heating start-up time, as shown in Figure 11, when looking at the heating start-up time from the outside temperature of 5℃ to 21℃, it took about 6 minutes with the conventional system, but with this new system. According to the example, it starts up in about 3 minutes. In other words, the time is reduced to about half.

After startup, it is clear that depending on the user's preference, it is possible to switch to gentle normal heating, as shown in FIG. It is clear that the main wind direction plate 2 can be rotated so as to gently blow out cold air in a substantially horizontal direction.

The aperture ratio of this embodiment, that is, the ratio Q/L of the length of the main wind direction plate 2 to the length of the outer wind direction plate 3, Q/L, and the relationship between the average temperature distribution of the above-floor 5Al and the relationship with noise have the relationship as shown in FIG. As is clear from the figure, 5 on the floor
The average temperature of 1 increases as the aperture ratio 111/L decreases, but the Ii sound also tends to increase exponentially. Therefore, for example, if the average temperature 5 cm above the floor is 21°C or higher, 1i sound 43
If the target is dB or less, the aperture ratio may be in the range of 0.4 to 0.8.

For safety, the aperture ratio Q/L is 0°65 in this example.
It is desirable to set it to 0.75.

In the above embodiments, the main wind direction plate 2 could be rotated manually or even by a motor such as a step motor. An example in which a motor is controlled by a microcomputer will be described.

According to this embodiment, the air conditioner is as shown in FIG.
It consists of an air conditioner main body 1 and an operation remote control 40. As shown in FIG. 13, the operation remote controller 40 includes a wind direction operation button 41 for instructing immediate operation of the wind direction plate motor 4, a temperature switching button 42 for changing the set temperature, and signals from these buttons. It consists of a microcomputer 43 that receives the data, processes it, and outputs a signal to a transmitting circuit 44.

The air conditioner main body 1 is also equipped with a microcomputer 54. In addition, a receiving circuit 55 for receiving signals from the transmitting circuit 44, a room temperature detector 56, etc. are also provided.

The microcomputer 54 includes a control section 59 and a storage section 60 that stores the number of pulses and set temperature of the wind direction plate motor, and the control section 59 controls data from the receiving circuit, room temperature detector, storage section, etc. , the calculated data is sent to the indoor fan motor 58., which is an external device. It is designed to output to the compressor 57, wind direction plate motor 4, etc.

Next, the operation will be explained using flowchart 1 shown in FIGS. 14 and 15. First, the operation remote control 40 will be explained with reference to FIG. 14. In step 5-31, the button 41.42 monitors the manual power.

If there is an input, determine the button type (step S
-32). When the operated button is the temperature switching button 42, a temperature signal is sent out (step S-33).

On the other hand, when the type of button is the wind direction operation button 41, a wind direction plate separation signal is sent out (step S-34). Note that this separation signal causes the main wind direction plate 2 and the outer wind direction plate 3 to
It is programmed so that if they are not separated, they will separate, and if they are separated by one, they will be integrated, resulting in the original blowout angle.

On the other hand, on the air conditioner body 1 side, 1! When the WX35 is on (step S-51), the storage unit 60 stores the initialization of the control unit 59, the number of wind direction plate motor pulses, and the set temperature.
Initialize the microcomputer, such as clearing the
52), Next, in step 5-53, the main wind direction plate 2 is driven by the wind direction plate motor 4, and the main wind direction #i2 and the outer wind direction plate 3 are initialized to the initial position 1, for example, the position shown in FIG. Do the following. Next, the receiving circuit 55 is initialized (step S-54).

When these initializations are completed, the received signal is monitored through the receiving circuit S5 (step S-55).

If there is a signal, the type of signal is determined in step S-56.
), when the signal is a wind direction plate separation signal, it is checked whether the wind direction plates are separated (step S-57). If the wind direction plate is not separated, the number of pulses of the wind direction plate motor 4 is written in the storage unit 60 (step S-58). Next, position the main wind direction plate 2 and the outer wind direction plate 3 together at the position vl.
(The position shown in Fig. 5)
9).

Furthermore, the separation position (the position shown in Figure 3), that is, the main wind direction plate 2
is rotated so that it is at an angle of 30 to 35 degrees from the vertical direction (step S-60).

Next, the rotation speeds of the indoor fan motor and compressor are calculated from the difference between the set temperature and the room temperature, and the indoor fan motor 58 and compressor 5 are
7 (Step 5-61.62).

Note that, for example, the following control table is used to calculate the rotational speeds of the indoor fan motor 58 and the compressor 57.

Indoor fan motor, compressor control table When the main wind direction plate 2 and the outer wind direction plate 3 are separated into reeds and the wind direction plate separation signal is received, it is not the time to start up, so the indoor fan motor 58゜Compression@57 is commanded to return to 2ir'ir'ili rotation (step S-63). Next, position the wind direction plate at position I! ! (Fig. 5) (Step S-64), and read the pulses of the wind direction plate motor stored in the storage unit 60 before separating the wind direction plate (Step S-64).
65), gives a command to the wind direction plate motor 4 (step S
-66).

On the other hand, if the type of signal is a temperature signal, the set temperature of the storage section 60 is also changed (step S-67).

It operates to normal operation (step S-68).

As described above, when the operation remote control 40 is used, simply by pressing the wind direction control button 41, the main wind direction board 2 and the outer wind direction board 3 will be separated if the wind direction boards are not separated, and will be integrated if they have already been separated. This results in the original air discharge direction, improving usability.

Note that when separated, the peripheral portion of the rjM opening 10 is closed by the outer wind direction plate 3, and most of the air volume is discharged from the main wind direction plate 2, while when integrated, it is discharged from the entire opening.

[Effect] As explained above, according to the present invention, the wind direction plate is composed of a main wind direction plate and an outer wind direction plate, and the outer wind direction plate has a position where it partially blocks the opening of the air conditioner main body, and a position where it partially blocks the opening of the air conditioner main body, and a position where the outer wind direction plate blocks a part of the opening of the air conditioner main body. Since we can take bg<position.

Even if the volume of the air blown out is the same, the speed of the air can be changed, so in combination with adjusting the wind direction, air conditioning can be performed quickly and gently.

Further, according to the present invention, by appropriately selecting the ratio of the lengths of the main wind direction plate and the outer wind direction plate, the effect of entrainment of surrounding air on the blown out cold and warm air flow is reduced, and the air reaches a long distance. be able to. Therefore, the temperature distribution in the air-conditioned space is improved and the comfortable temperature zone is expanded.
