Description

  The present invention relates to a deodorizing apparatus equipped with a UV lamp, and more particularly to an apparatus for improving the life and brightness of a UV lamp.

  Conventionally, UV lamps that irradiate ultraviolet rays are known. When the lamp is lit when the ambient temperature is low, the lamp has the property of shortening the lifetime or lowering the brightness.

  Among these, there is a technique for improving the luminance characteristics of the lamp by paying attention to the property that the luminance of the lamp decreases when the ambient temperature is low. As an example of this technique, an illumination device including a lamp and a heater for heating the lamp has been proposed (see, for example, Patent Document 1). In this illumination device, a heater is disposed in the vicinity of the lamp. According to this illuminating device, the ambient temperature of the lamp can be increased by the heater, so that high luminance characteristics can be obtained from the start of lighting of the lamp.

  UV lamps are also used in deodorizers. An example of this deodorizing apparatus will be described. This deodorizing apparatus includes a housing having an air inlet and an outlet, and an air passage connecting the inlet and the outlet. In the air passage, a blower for sending air sucked from the suction port from the blowout port is arranged. Further, a UV lamp is disposed in the air passage. The UV lamp generates ozone by irradiating the air passing through the air passage with ultraviolet rays. By the action of the generated ozone, the air passing through the air passage is sterilized and deodorized. Air that has been sterilized and deodorized is blown out from the air outlet.

  As for the deodorizing apparatus described above, the brightness of the UV lamp is lowered when the UV lamp is turned on when the ambient temperature is low. In the deodorizing device, it is conceivable to arrange a heater in the vicinity of the UV lamp in order to improve the property that the luminance of the UV lamp is lowered as in the above-described lighting device.

  However, if a heater is arranged in the vicinity of the UV lamp, the UV lamp cannot irradiate ultraviolet rays into the air passage space that is hidden by the heater due to the presence of the arranged heater. Thus, when the space which cannot irradiate an ultraviolet-ray arises, the irradiation amount of the ultraviolet-ray to the air by a UV lamp will decrease. Therefore, in the deodorizing apparatus provided with a heater in the vicinity of the UV lamp, there is a problem that the amount of ozone generated by irradiation with ultraviolet rays is reduced, and the performance of sterilizing air and deodorizing by the action of ozone is lowered.

Japanese Patent Laid-Open No. 10-020307 (page 2 to page 3, FIGS. 1 to 2)

  In view of the above problems, the present invention provides an air passage that suppresses a decrease in luminance of a UV lamp without providing a heater in the vicinity of the UV lamp when the external environment of the deodorizing apparatus including the UV lamp is in a low temperature environment. An object of the present invention is to provide a deodorizing apparatus capable of ensuring the effects of sterilization and deodorization of air passing through the air.

  In order to solve the above-mentioned problems, a deodorizing apparatus according to the present invention has a housing having an air inlet and an air outlet and an air passage connecting the air inlet and the air outlet, and an air sucked from the air inlet. A blower that discharges from the outlet, a heater that is disposed in the air passage and that heats and regenerates the deodorizing filter that deodorizes the air, and a UV lamp that is disposed downstream of the air passage and irradiates air with ultraviolet rays. And a control unit that controls the drive of the blower, the energization of the heater, and the energization of the UV lamp, and the control unit drives the blower and energizes the UV lamp during the deodorizing operation of the deodorizing device. At least energize the heater.

  Further, the deodorizing apparatus of the present invention includes a housing having an air passage having an air inlet and an outlet, and an air passage connecting the inlet and the outlet, and a blower that releases air sucked from the inlet from the outlet. And a heater for heating and regenerating the deodorizing filter disposed in the air passage to deodorize the air, a UV lamp disposed on the downstream side of the air passage from the heater and irradiating the air with ultraviolet rays, and driving of the blower And a control unit for controlling the energization of the heater and the energization of the UV lamp, provided with a temperature sensor for detecting the ambient temperature of the UV lamp, and the control unit is controlled by the temperature sensor during the deodorizing operation of the deodorizing device. When the detected value is equal to or less than the predetermined value, at least the heater is energized while the blower is driven and the UV lamp is energized.

  According to the deodorizing apparatus of the present invention, during the deodorizing operation, the control unit heats the air sucked from the suction port while passing through the periphery of the heater by energizing at least the heater while driving the blower and energizing the UV lamp. The UV lamp can be warmed by the heated air. As a result, when the external environment of the deodorizing apparatus equipped with the UV lamp is in a low temperature environment, it is possible to remove the air passing through the air passage while suppressing a decrease in the brightness of the UV lamp without providing a heater in the vicinity of the UV lamp. The effect of bacteria and deodorization can be ensured. Further, when the external environment of the deodorizing apparatus including the UV lamp is in a low temperature environment, the UV lamp can be warmed without providing a heater in the vicinity of the UV lamp, so that the life of the UV lamp can be extended. .

  Further, according to the deodorizing apparatus of the present invention, during the deodorizing operation, when the ambient temperature of the UV lamp is equal to or lower than the predetermined value, the control unit energizes at least the heater while driving the blower and energizing the UV lamp. In addition to the effects of the invention, only when the deodorizing apparatus including the UV lamp is used in a low temperature environment, the UV lamp is heated with heated air, so that power consumption during the deodorizing operation can be reduced.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the deodorizing apparatus according to the present embodiment has a casing 10 that has a vertically long, substantially rectangular parallelepiped shape. A front panel 32 is formed on the front side of the housing 10, and a back panel 34 is formed on the back side facing the front panel 32. The rear panel 34 is formed with an air inlet 26 provided with a large number of openings.

  An operation panel 44 and a rectangular louver 30 adjacent to the operation panel 44 are disposed on the upper surface of the housing 10. The operation panel 44 is provided with various buttons and display lamps for the user to operate the deodorizing apparatus. The louver 30 can be manually opened and closed, and serves as an air outlet 28 described later.

  Next, the internal configuration of the housing 10 will be described. As shown in FIG. 3, an air passage 20 that connects the inlet 26 and the outlet 28 is provided inside the housing 10. In the air passage 20, a pre-filter 50, a dust collection filter 52, a heater deodorizing unit 54, a vaporization filter 14, a blower 12, an ozone generation unit 16, and a negative ion generator 46 are arranged. These components are arranged in the above-described order from the upstream side to the downstream side of the air passage 20.

  The prefilter 50 is a filter that collects relatively large floating matters such as dust and pet hair, and the dust collection filter 52 is a small floating matter such as dust or pollen that could not be collected by the prefilter 50. A pleated filter for collecting.

  The heater deodorizing unit 54 includes a deodorizing filter 54a and a heater 54b. The deodorizing filter 54a is a catalytic filter that adsorbs and decomposes high-concentration odor components such as oily odors and tobacco and pet odors. The heater 54b is a sheath heater bent in a meandering manner so as to follow the surface of the deodorizing filter 54a. The heater 54b heats the deodorizing filter 54a, thereby promoting the decomposition of the adsorbed odor component and regenerating the deodorizing performance.

  The vaporization filter 14 is a pleated filter having air permeability and water absorption. The vaporization filter 14 is always wet by absorbing water stored in a tray (not shown). Humidity is given to the air by letting the air pass through the vaporizing filter in a wet state.

  The blower 12 includes a fan motor 12a and a fan 12b driven by the fan motor 12a. The blower 12 rotates the fan 12b by driving the fan motor 12a, thereby sucking air from the suction port 26 (white arrow A), and sending the sucked air from the blowout port 28 through the air passage 20 (white). A blank arrow E).

  The ozone generation unit 16 includes a case 16a, a UV lamp 16b, and an ozone decomposition catalyst 16c. Case 16a is comprised by the substantially rectangular parallelepiped shape long in the horizontal direction of a deodorizing apparatus. The case 16 a has an air inlet 161 formed at a position facing the air passage 20, and an air outlet 162 formed at a position communicating with the air outlet 28. An air flow path 160 that connects the inflow port 161 and the outflow port 162 is provided in the case 16a. The ozone generation unit 16 forms an air flow path 160 that branches from the air passage 20 between the blower 12 and the blower outlet 28, so that the air flow path 160 merges with the blower outlet 28 via the outlet 162. Is provided. The ozone generation unit 16 takes in air from the inflow port 161 (open arrow C), and causes the taken-in air to flow out from the outlet 28 via the air flow path 160 (open arrow F). In the air flow path 160, a UV lamp 16b and an ozone decomposition catalyst 16c are arranged. These components are arranged in the above-described order from the upstream side to the downstream side of the air flow path 160.

  The UV lamp 16b is a straight tube lamp, and is disposed so as to be orthogonal to the flow of air passing through the air flow path 160 along the horizontal direction of the case 16a. The UV lamp 16b irradiates the air passing through the air flow path 160 with ultraviolet rays. In the ozone generation unit 16, the ultraviolet rays are irradiated to the air, and the ultraviolet rays are combined with oxygen in the air to generate ozone. The ozone generated in the ozone generation unit 16 sterilizes and deodorizes the air passing through the air flow path 160. The ozone decomposition catalyst 16c decomposes ozone by the action of a metal catalyst such as titanium oxide in order to reduce the ozone concentration when air containing ozone generated in the ozone generation unit 16 flows out from the outlet 162. Is.

  In the ozone generation unit 16, an ozone duct 18 is formed that extends from between the UV lamp 16 b and the ozone decomposition catalyst 16 c disposed in the air flow path 160 to the wind surface of the vaporization filter 14. At the tip of the ozone duct 18, a blowing port 18 a is formed on the wind surface of the vaporization filter 14 to spray ozone generated by the irradiation of ultraviolet rays from the UV lamp 16 b.

  The negative ion generator 46 is disposed in the air passage 20 near the air outlet 28 and includes a discharge electrode and a ground electrode. The negative ion generator 46 generates a corona discharge between the discharge electrode and the ground electrode when, for example, a high voltage of several kV is applied between the discharge electrode and the ground electrode by the DC high-voltage power source. The electrons released in the above combine with atoms and molecules in the air to generate negative ions.

  In addition, a main board 40 is disposed above the pre-filter 50 and the dust collection filter 52 in the housing 10, and a power supply unit 56 and a control unit 41 described later are mounted on the main board 40. The control unit 41 receives a driving instruction signal determined by pressing various buttons from the operation panel 44. The control unit 41 also controls the driving of the fan motor 12a, the energization of the UV lamp 16b, the energization of the heater 54b, and the like.

  Next, the flow of air passing between the inlet 26 and the outlet 28 of the deodorizing apparatus described above will be described. It is assumed that the louver 30 is open as shown in FIG. During the deodorizing operation of the deodorizing apparatus, the air (white arrow A) sucked from the suction port 26 is dedusted and deodorized while passing through the prefilter 50, the dust collection filter 52 and the heater deodorizing unit 54. Next, the dust-removed and deodorized air is humidified while passing through the vaporization filter 14.

  The humidified air is sent upward by the blower 12 (open arrow B). Next, most of the delivered air is blown out from the blowout port 28 (open arrow E).

  Moreover, a part of the sent-out air is taken into the ozone generation unit 16 from the inflow port 161 (open arrow C). The taken-in air is irradiated with ultraviolet rays by the UV lamp 16b. Ozone is generated in the ozone generation unit 16 by irradiation of the taken-in air with ultraviolet rays. The generated ozone disinfects molds and viruses floating in the taken-in air, and decomposes low-concentration odor components that could not be decomposed by the deodorizing filter 54a.

  The generated air containing ozone is decomposed by the ozone decomposition catalyst 16c. By decomposing ozone, it becomes air containing low concentration (0.02 ppm or less) ozone, and this air containing low concentration ozone is blown out from the outlet 28 through the outlet 162 (open arrow F). . The low-concentration ozone blown out decomposes odorous components that permeate curtains, carpets, and the like arranged outside the deodorizer.

  Further, a part of the generated ozone is attracted into the ozone duct 18 by the action of this pressure difference because the vicinity of the wind surface of the vaporization filter 14 has a negative pressure and the vicinity of the ozone generation unit 16 has a positive pressure ( Arrow D). The attracted ozone is sprayed on the wind surface of the vaporization filter 14 from the spray port 18a. The ozone blown to the vaporization filter 14 sterilizes the vaporization filter 14 while passing through the vaporization filter 14 together with the air sucked from the suction port 26, and keeps the vaporization filter 14 in a clean state.

  The negative ions generated by the negative ion generator 46 are released by riding on the air (white arrow E) blown from the outlet 28. The released negative ions adhere to microorganisms such as molds and viruses floating in the air outside the deodorizing apparatus and inactivate them.

  Next, the electrical configuration of the deodorizing apparatus will be described with reference to FIG. In addition, the deodorizing apparatus of this embodiment has the deodorizing function by the deodorizing filter 54a and the UV lamp 16b, the heating regeneration function of the deodorizing filter 54a, the sterilizing function by the negative ion generator 46, and the humidifying function by the vaporizing filter 14. However, since the electrical configuration related to the sterilization function and the humidification function is not directly related to the present invention, the description thereof is omitted.

  As shown in FIG. 4, the control unit 41 includes a switch unit 41a, an inverter unit 41b, a motor drive unit 41c, a heater energization unit 41d, and a control unit 41e. The control unit 41 is connected to the power supply unit 56, the remote control receiving unit 58, the operation panel 44, and the temperature sensor 60 with lead wires (not shown). Further, the control unit 41 is connected to the heater 54b provided in the heater deodorizing unit 54, the fan motor 12a, and the UV lamp 16b in the ozone generation unit 16 by lead wires (not shown).

  The power supply unit 56 is connected to an outlet via the power cord 62, and generates a DC voltage necessary for the deodorizing operation of the deodorizing apparatus by the electric power supplied via the outlet. The power supply unit 56 applies the generated DC voltage to the switch unit 41a and the control unit 41e. The switch unit 41a turns this DC voltage on and off, and the inverter unit 41b boosts the DC voltage via the switch unit 41a to a voltage that can drive the UV lamp 16b.

  The remote control receiving unit 58 is disposed on the operation panel 44, receives an infrared remote control signal, and transmits it to the control unit 41e. As described above, the operation panel 44 transmits a driving instruction signal by pressing various buttons to the control unit 41e. The temperature sensor 60 is attached in the ozone generation unit 16 or in the vicinity of the suction port 26, and detects the ambient temperature of the UV lamp 16b. Moreover, the temperature sensor 60 transmits the detection signal to the control part 41e. The remote control receiver 58 receives a driving instruction signal as a remote control signal in the same manner as the operation panel 44. The temperature sensor 60 is used when the control unit 41 determines whether to energize the heater 54b according to the ambient temperature of the UV lamp 16b in the deodorizing operation for deodorizing the air passing through the air passage 20. It is. The determination whether or not to energize the heater 54b may be omitted, and the heater 54b may be energized at all times during the deodorizing operation. In this case, the temperature sensor 60 may not be provided.

  The motor drive unit 41c drives the fan motor 12a, and the heater energization unit 41d controls energization to the heater 54b. The control unit 41e receives signals from the remote control reception unit 58, the operation panel 44, and the temperature sensor 60. Moreover, the control part 41e transmits a control signal to the switch part 41a, the motor drive part 41c, and the heater energization part 41d. The control unit 41e controls the energization of the UV lamp 16b by transmitting an on / off signal to the switch unit 41a and turning on and off the DC voltage applied to the inverter unit 41b. In addition, the control part 41e has a different control program with the case where there is no temperature sensor 60, and the case where it has the temperature sensor 60, and controls operation | movement of a deodorizing apparatus according to these control programs.

  Next, the deodorizing operation and heating regeneration operation of the deodorizer will be described with reference to FIGS. The deodorizing operation is an operation of driving the blower 12 and deodorizing the air passing through the air passage 20 using the deodorizing filter 54a and the ozone generation unit 16. This deodorization operation has two types of operation: heating the UV lamp 16b in the ozone generation unit 16 by energizing the heater 54b to turn on the UV lamp 16b, and generating ozone without energizing the heater 54b. There is an operation of turning on the UV lamp 16b in the unit 16. The heating regeneration operation is an operation for heating and regenerating the deodorizing filter 54 a by energizing the heater 54 b without driving the blower 12 and passing air through the air passage 20.

  First, Example 1 which shows the deodorizing driving | operation operation | movement when there is no temperature sensor 60 is demonstrated using FIG. 5 (A). As shown in FIG. 5A, when the control unit 41e receives an operation instruction signal indicating the start of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, the control unit 41e turns on the energization to the heater 54b (1). . The control unit 41e transmits an energization control signal for turning on the energization of the heater 54b to the heater energization unit 41d. The above-described driving instruction signal includes air flow rate information (for example, strong wind) by a button operation of a remote control transmitter (not shown) or a user of the operation panel 44.

  Next, the controller 41e turns on the drive of the fan motor 12a after a predetermined time t1 has elapsed since the energization of the heater 54b was turned on (2). The predetermined time t1 is a time (for example, 10 minutes) in which the vicinity of the heater 54b is sufficiently warmed even when the external environment of the deodorizing apparatus changes. The controller 41e transmits a drive control signal for turning on the fan motor 12a to the motor driver 41c. The above-described drive control signal includes the rotation speed information (for example, high speed) of the fan motor 12a according to the air flow information. The motor drive unit 41c drives the fan motor 12a at a speed according to the rotation speed information.

  Next, the control unit 41e turns on the energization to the UV lamp 16b after a predetermined time t2 has elapsed since the fan motor 12a is turned on (3). The predetermined time t2 is a time (for example, 1 minute) in which the air sucked from the suction port 26 is warmed by the heater 54b and the surroundings of the UV lamp 16b in the ozone generation unit 16 are sufficiently warmed by the warmed air. The control unit 41e transmits an ON signal to the switch unit 41a, and the inverter unit 41b boosts the applied DC voltage to the driving voltage of the UV lamp 16b, and applies this driving voltage to the UV lamp 16b.

  Next, when receiving an operation instruction signal indicating the end of the deodorizing operation from the remote control receiver 58 or the operation panel 44, the controller 41e turns off the power to the heater 54b and the UV lamp 16b, and turns off the fan motor 12a. At the same time. The control unit 41e transmits an energization control signal for turning off the energization of the heater 54b to the heater energization unit 41d. The control unit 41e transmits a drive control signal for turning off the drive of the fan motor 12a to the motor drive unit 41d. Further, the control unit 41e transmits an off signal to the switch unit 41e. As a result, the DC voltage from the switch unit 41e is not applied to the inverter unit 41b.

  According to the first embodiment described above, the air heated by the heater 54b is turned on by supplying power to the UV lamp 16b after a predetermined time has elapsed after the heater 54b is turned on and the fan motor 12a is turned on. Is sent to the UV lamp 16b, and the ambient temperature of the UV lamp 16b rises. As a result, when the energization of the UV lamp 16b is turned on, it can be lit with high luminance. From the above, when the external environment of the deodorizing apparatus including the UV lamp 16b is in a low temperature environment, the ozone generation unit can suppress the decrease in the luminance of the UV lamp 16b without providing a heater in the vicinity of the UV lamp 16b. The effect of the sterilization and deodorization of air in 16 can be ensured. Further, when the external environment of the deodorizing apparatus including the UV lamp 16b is in a low temperature environment, the UV lamp 16b can be warmed without providing a heater in the vicinity of the UV lamp 16b. can do.

  In the first embodiment, the control unit 41e controls the fan motor 12a and the UV lamp 16b based on the predetermined time t1 and the predetermined time t2 stored in advance in a storage unit (not shown). However, the present invention is not limited to this, and the control unit 41 may control the energization on of the heater 54b and the UV lamp 16b and the drive on of the fan motor 12a at the same timing. In this case, since the energization on the heater 54b, the drive on the fan motor 12a, and the energization on the UV lamp 16b are performed at the same timing, the ambient temperature of the UV lamp 16b is the same as when the energization of the UV lamp 16b is on. Although it is low, the ambient temperature of the UV lamp 16b increases with time. At this time, the UV lamp 16b can be turned on with high luminance.

  Next, the heating regeneration operation when the temperature sensor 60 is not provided will be described with reference to FIG. The control unit 41e is in a state where a DC voltage from the power supply unit 56 is applied. As shown in FIG. 5 (B), the control unit 41e turns on the energization of the heater 54b every preset cumulative operating time (for example, 24 hours) of the deodorizing operation (1). The control unit 41e automatically transmits an energization control signal for turning on the energization of the heater 54b to the heater energization unit 41d every accumulated time.

  Next, the control unit 41e turns off the power supply to the heater 54b after a preset time (for example, 1 hour) elapses after the power supply to the heater 54b is turned on. When the heater 54b is energized, the drive of the fan motor 12a and the energization of the UV lamp 16b remain off. Therefore, the UV lamp 16b does not operate in the heating regeneration operation. The control unit 41e automatically transmits an energization control signal for turning off the energization of the heater 54b to the heater energization unit 41d. By this heating and regenerating operation, the deodorizing filter 54a is heated by the heater 54b to regenerate the deodorizing performance.

  Next, Example 2 which shows the deodorizing driving | operation operation | movement in the case of having the temperature sensor 60 is demonstrated using FIG. 6 (A) and FIG. 6 (B). In addition, the description which overlaps with Example 1 is abbreviate | omitted. As shown in FIG. 6A, when the control unit 41e receives a driving instruction signal indicating the start of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, the detected value of the temperature sensor 60 at this time is a predetermined value. When the temperature is below (for example, 10 ° C.), the energization to the heater 54b is turned on (1).

  Next, the controller 41e turns on the drive of the fan motor 12a after a predetermined time t1 has elapsed since the energization of the heater 54b was turned on (2). The predetermined time t1 is a time (for example, 10 minutes) in which the vicinity of the heater 54b is sufficiently warmed with respect to the average outside air temperature in winter.

  Next, as in the first embodiment, the control unit 41e turns on the energization of the UV lamp 16b after a predetermined time t2 has elapsed since the fan motor 12a is turned on (3). Next, as in the first embodiment, when the control unit 41e receives an operation instruction signal indicating the end of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, the power supply to the heater 54b and the UV lamp 16b is turned off, and the fan The motor 12a is turned off at the same timing.

  Further, as shown in FIG. 6B, when the control unit 41e receives an operation instruction signal indicating the start of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, the detected value of the temperature sensor 60 at this time is When it is larger than a predetermined value (for example, 10 ° C.), the energization to the heater 54b is kept off (1). The control unit 41e turns on driving of the fan motor 12a (2) and energization on the UV lamp 16b (3) at the same timing. Next, when the control unit 41e receives an operation instruction signal indicating the end of the deodorizing operation from the remote control reception unit 58 or the operation panel 44, the drive off of the fan motor 12a and the energization off of the UV lamp 16b are at the same timing. To do.

  Next, the heating regeneration operation when the temperature sensor 60 is provided will be described with reference to FIG. As shown in FIG. 6C, the control unit 41e turns on the energization of the heater 54b every preset cumulative operation time (for example, 24 hours) of the deodorizing operation, as in the first embodiment. (1). Next, similarly to the first embodiment, the control unit 41e turns off the power supply to the heater 54b after a preset time (for example, 1 hour) has elapsed since the power supply to the heater 54b is turned on. When the heater 54b is energized, the drive of the fan motor 12a and the energization of the UV lamp 16b remain off. Therefore, the UV lamp 16b does not operate in the heating regeneration operation. By this heating and regenerating operation, the deodorizing filter 54a is heated by the heater 54b to regenerate the deodorizing performance.

  According to the second embodiment described above, energization of the heater 54b and energization of the UV lamp 16b after a lapse of a predetermined time after the fan motor 12a is turned on cause the air heated by the heater 54b to flow. Is sent to the UV lamp 16b, and the ambient temperature of the UV lamp 16b rises. As a result, when the energization of the UV lamp 16b is turned on, it can be lit with high luminance. From the above, the same effect as in the first embodiment can be obtained. Also, compared to the first embodiment in which the energization to the heater 54b is always turned on during the deodorizing operation because the UV lamp 16b is heated with heated air only when the deodorizing apparatus including the UV lamp 16b is used in a low temperature environment. In addition, it is possible to reduce power consumption accompanying energization of the heater 54b during the deodorizing operation.

  Next, Example 3 which shows the deodorizing driving | operation operation | movement in the case of having the temperature sensor 60 is demonstrated using FIG. 7 (A) and FIG. 7 (B). In addition, the description which overlaps with Example 1 and Example 2 is abbreviate | omitted. As shown in FIG. 7A, when the control unit 41e receives a driving instruction signal indicating the start of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, as in the second embodiment, the temperature sensor at this time point When the detected value of 60 is a predetermined value (for example, 10 ° C.) or less, energization to the heater 54b is turned on (1).

  Next, the control unit 41e starts driving the fan motor 12a at the same timing as the energization of the heater 54b, and takes a predetermined time t1 (for example, 10 minutes) to make the fan motor 12a respond to the rotation speed information. Control is performed so as to achieve a speed (for example, high speed) (2). The predetermined time t1 is a time during which the vicinity of the heater 54b is sufficiently warmed as in the second embodiment.

  Next, the control unit 41e turns on the energization of the UV lamp 16b after a predetermined time t2 (for example, 1 minute) has elapsed since the fan motor 12a has reached the speed corresponding to the rotational speed information (3). Next, similarly to the second embodiment, when the control unit 41e receives an operation instruction signal indicating the end of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44, the power supply to the heater 54b and the UV lamp 16b is turned off, and the fan The motor 12a is turned off at the same timing.

  Further, as shown in FIG. 7B, when the control unit 41e receives a driving instruction signal indicating the start of the deodorizing operation from the remote control receiving unit 58 or the operation panel 44 as in the second embodiment, When the detected value of the temperature sensor 60 is larger than a predetermined value (for example, 10 ° C.), the energization to the heater 54b is kept off (1). As in the second embodiment, the control unit 41e turns on the drive of the fan motor 12a (2) and turns on the energization of the UV lamp 16b (3) at the same timing. Next, as in the second embodiment, when receiving the operation instruction signal indicating the end of the deodorizing operation from the remote control receiver 58 or the operation panel 44, the control unit 41e turns off the fan motor 12a and sends it to the UV lamp 16b. Is turned off at the same timing.

  Next, the heating regeneration operation in the case where the temperature sensor 60 is provided will be described with reference to FIG. As shown in FIG. 7C, the control unit 41e turns on the energization of the heater 54b every preset cumulative operation time (for example, 24 hours) of the deodorizing operation, as in the second embodiment. (1). Next, as in the second embodiment, the control unit 41e turns off the power supply to the heater 54b after a preset time (for example, 1 hour) has elapsed since the power supply to the heater 54b is turned on. When the heater 54b is energized, the drive of the fan motor 12a and the energization of the UV lamp 16b remain off. Therefore, the UV lamp 16b does not operate in the heating regeneration operation. By this heating and regenerating operation, the deodorizing filter 54a is heated by the heater 54b to regenerate the deodorizing performance.

  According to the third embodiment described above, the same effects as those of the second embodiment can be obtained, and the following effects can also be obtained. At the start of the deodorizing operation of the deodorizing device, if the ambient temperature of the UV lamp 16b is low and the flow of warmed air passing around the UV lamp 16b is fast, the heat conduction efficiency of the air to the UV lamp 16b may be deteriorated. is there. In the third embodiment, the rotational speed of the fan motor 12a is gradually increased in accordance with the process in which the ambient temperature of the UV lamp 16b shifts from a low state to a high state as time passes when the heater 54b is energized. . As a result, the heat conduction efficiency of air with respect to the UV lamp 16b can be improved and the UV lamp 16b can be easily heated.

  Next, referring to FIG. 8, in the deodorizing operation operation in which the UV lamp 16b is heated and the UV lamp 16b is turned on in the second embodiment, the heater motor 12b is energized from when the heater 54b is energized according to the detected value of the temperature sensor 60. Modification 1 in which the predetermined time t1 until the drive is turned on will be described.

  As shown in FIG. 8, in the control part 41e, when the detected value of the temperature sensor 60 becomes 10 degrees C or less, the detected value is divided into three temperature ranges. The controller 41e sets the predetermined time t1 to a different time according to the divided temperature range. Therefore, the controller 41e sets the predetermined time t1 to 5 minutes when the temperature range is 10 ° C. or lower and higher than 0 ° C., 8 minutes when the temperature range is 0 ° C. or lower and higher than −10 ° C., and 10 minutes when the temperature range is −10 ° C. or lower. Set. For example, when the detected value of the temperature sensor 60 is 5 ° C., the control unit 41e sets the predetermined time t1 to 5 minutes.

  According to the first modification, the lower the ambient temperature of the UV lamp 16b is, the longer the time from turning on the heater 54b to turning on the fan motor 12a is set. Thereby, the air heated by the heater 54b can be sent to the UV lamp 16b after the temperature of the heater 54b itself is stabilized regardless of the external environment of the deodorizing apparatus.

  Next, in FIG. 9, in the deodorizing operation operation in which the UV lamp 16b is warmed and the UV lamp 16b is turned on in the second embodiment, the rotation speed of the fan motor 12b (of the fan 12b) is determined according to the detected value of the temperature sensor 60. Modification 2 in which the air flow rate is adjusted will be described.

  As shown in FIG. 9, in the control part 41e, when the detected value of the temperature sensor 60 becomes 10 degrees C or less, the detected value is divided into three temperature ranges. The controller 41e sets the rotational speed of the fan motor 12b to be different depending on the divided temperature range. Therefore, the control unit 41e sets the rotational speed information of the fan motor 12b to a high speed when the temperature range is 10 ° C. or lower and higher than 0 ° C., a medium speed when the temperature range is lower than 0 ° C. or higher than −10 ° C., and a low speed when the temperature range is −10 ° C. or lower. Set as follows. For example, when the detected value of the temperature sensor 60 is 5 ° C., the control unit 41e controls the speed of the fan motor 12a to a high speed so that the air flow rate of the fan 12b becomes a strong wind. Note that the air flow rate information of the fan 12b with respect to the rotational speed information of the fan motor 12a includes strong wind when the temperature range is 10 ° C. or lower and over 0 ° C., weak wind when the temperature range is lower than 0 ° C. or higher than −10 ° C. It is.

  In the second modification, in addition to the effects of the second embodiment, the following effects can be obtained. At the start of the deodorizing operation of the deodorizing device, if the ambient temperature of the UV lamp 16b is low and the flow of warmed air passing around the UV lamp 16b is fast, the heat conduction efficiency of the air to the UV lamp 16b is deteriorated. According to the second modification, the rotation speed of the fan motor 12a is controlled to decrease as the ambient temperature of the UV lamp 16b decreases when the heater 54b is energized. As a result, the heat conduction efficiency of air with respect to the UV lamp 16b can be improved and the UV lamp 16b can be easily heated.

  As a modified example of the deodorizing operation that warms the UV lamp 16b and lights the UV lamp 16b in the third embodiment, as shown in FIG. 8, according to the detection value of the temperature sensor 60, as shown in FIG. The predetermined time t1 may be adjusted. In this case, the same effect as that of the first modification can be obtained.

  Next, another modified example 3 of the deodorizing operation that warms the UV lamp 16b common to the first to third embodiments and lights the UV lamp 16b will be described with reference to FIG. In the first to third embodiments, the control unit 41e outputs an energization control signal indicating a constant value as the energization current value to the heater 54b to the heater energization unit 41d. As shown in FIG. 10, in the control unit 41e, as the temperature of the heater 54b, the temperature when the UV lamp 16b is heated and the UV lamp 16b is turned on is lower than the temperature when the deodorizing filter 54a is heated and regenerated. Thus, the energization current value of the heater 54b is changed.

  As shown in FIG. 10, when the UV lamp 16b is warmed by turning on the UV lamp 16b in the deodorizing operation, the controller 41e reduces the energization current value of the heater 54b so that the temperature of the heater 54b becomes, for example, 30 ° C. Set. The control unit 41e outputs an energization control signal based on the above setting to the heater energization unit 41d, and the heater energization unit 41d decreases the energization current value to the heater 54b.

  On the other hand, when the deodorizing filter 54a is heated and regenerated by the heater 54b, the control unit 41e sets the energization current value of the heater 54b large so that the temperature of the heater becomes 80 ° C., for example. The control unit 41e outputs an energization control signal based on the above setting to the heater energization unit 41d, and the heater energization unit 41d increases the energization current value to the heater 54b.

  According to the third modification, in the deodorizing operation in which the UV lamp 16b is warmed and the UV lamp 16b is turned on, the temperature of the heater 54b does not become a temperature at which the deodorizing filter 54a is heated and regenerated. No odor is generated when the deodorizing filter 54a is heated and regenerated. As a result, it is possible to prevent odors from being discharged from the outlet 28 in the deodorizing operation in which the heater 54b is energized to warm the UV lamp 16b and turn on the UV lamp 16b.

  In addition, although this embodiment demonstrated the deodorizing apparatus provided with the ozone generation unit 16 and the heater deodorizing unit 54, this invention is not restricted to this, The air cleaner provided with an ozone generation unit and a heater deodorizing unit, The present invention can be applied to an air conditioner that includes an ozone generation unit and that takes in warm air blown out from the outlet during heating operation into the ozone generation unit.

  In the present embodiment, the fan motor 12a is driven after the elapse of the predetermined time t1 since the energization of the heater 54b is turned on, and further the energization of the UV lamp 16b is turned on after the elapse of the predetermined time t2. When the temperature sensor 60 is provided in the ozone generation unit 16, the energization on / off of the UV lamp 16b may be controlled based on the temperature detected by the temperature sensor 60. For example, after turning on the heater 54b and turning on the fan motor 12a, the UV lamp 16b is turned on when the temperature sensor 60 detects a temperature of 10 ° C. or higher. In such a case, control such as turning off the energization of the UV lamp 16b is possible. According to such control, since the energization on / off of the UV lamp 16b is controlled based on the actual measured value of the ambient temperature of the UV lamp 16b, the life and brightness of the UV lamp 16b can be improved more reliably. .
