A fan motor 20 and a fan 21 are provided. A water receiving tray 22 and a drain port 23 are provided below the evaporator 18 and the condenser 19, and a drainage tank 24 is provided below the water receiving tray 22 and the drain port 23.
In the drainage tank 24, there is a full water detecting unit 48. There is an air purifier 31 on the back, and the suction port 29, filter 28, blast electrode 25, dust collecting electrode 26,
There is a deodorizing filter 27 and an outlet 16. Further, a door 32 is provided outside the air cleaning section 31.

FIG. 2 is a perspective view of the present embodiment, in which the door 32 is removed. FIG. 3 shows a state without the door 32 of FIG.

FIG. 4 is a diagram showing an electric circuit of this embodiment.
An operation switch 34 has four circuits in the operation switch 34. Reference numeral 34a denotes a current switch 35, a door opening / closing control means 36, an air cleaning controller 37, and an electrode terminal 38 which are connected during dehumidification, no airflow, and air blowing operation. Reference numeral 34b denotes a current switch 39 and a two-way valve 4 which are connected during the dehumidifying and blowing operations.
1. The compressor motor 42 is an electronic control unit 43 such as a relay.
Is connected to the full water switch 44. The full-water switch 44 is operated by the compressor motor-4 according to the signal of the full-water detector 48.
2. The operation of the fan motor 40 and the like can be stopped. 34c is connected to the fan motor 40 during the dehumidifying operation. Reference numeral 34d is commonly connected via a thermal fuse.

The operation of the operation switch 34 will be described.
Is selected, a voltage is applied to the compressor motor 42 and the fan motor 40, the compressor 17 and the fan motor 20 start operating, and the fan 21 rotates. The air sucked in from the suction port 14 dehumidifies the moisture in the evaporator 18, is heated and dried in the condenser 19, is blown out into the room from the outlet 15, and dehumidifies the humidity in the room. At this time, the dehumidified water generated by the evaporator 18 drops from a drain port 23 provided in a water receiving tray 22 and accumulates in a drain tank 24.

At the same time, a voltage is applied to the air purifying control device 37, so that a voltage is applied to the electrode terminal portion 38, and the air drawn from the suction port 29 by the blast electrode 25 is discharged by the dust collecting electrode 26 into dust in the air. , Dust, pollen and the like are adsorbed and blown out from the outlet 16 through the deodorizing filter 27 to purify the indoor air. At this time, if the indoor humidity is high and operation has been performed for a long time, the drain water
Before being overflowed from the main body, the full-water detector 48 detects that the water is full, sends a signal to the full-water switch 44, and the full-water switch 44 stops only the dehumidifying operation. Therefore, the room is not wet with the dehumidified drain water, and since the air purification control device 37 is continuously energized, clean air can be continuously and efficiently produced for a long time, and a comfortable living environment can be provided. .

Also, when the dust collecting electrode 26 has been used for a long time and the dust collecting electrode 26 has been cleaned by opening the door 32 for cleaning due to dirt with dust, dust, pollen or the like adsorbed by the dust collecting electrode 26, The opening and closing of the door 32 is detected by the unit 33 and a signal is sent to the door opening and closing control unit 36. Since the door opening and closing control unit 36 shuts off only the current supply from the air purification control device 37 to the electrode terminal unit 38, the dehumidifying operation is stopped. Since there is no room, it is possible to continuously and efficiently dehumidify the room for a long time and provide a comfortable living environment.

When "no wind" is selected by the operation switch 34, the voltage is applied only to the air purifying control device 37, so that a voltage is applied to the electrode terminal portion 38 and the air drawn from the suction port 29 by the blast electrode 25 is The dust collecting electrode 26 adsorbs dust, dust, pollen and the like in the air, and the deodorizing filter 2
The air is blown out from the air outlet 16 through the air outlet 7 and clean air can be continuously produced for a long time with low noise and with low power consumption, and a comfortable living environment can be provided.

Further, when "Blow" is selected by the operation switch 34, a voltage is applied to the air purifying control device 37 and the fan motor 40, so that the air can be rapidly purified by the blowing effect of the fan 21 so that a comfortable living environment can be obtained. Can be provided.

Further, since the current switches 35 and 39 are provided in the circuit 34a of the air cleaning control device 37 and the dehumidification-related circuit 34b of the electronic control device 43, even if an overcurrent flows and the circuit needs to be cut off, both of them are provided. Since the function is not impaired, the humidity of the living space can be kept at an appropriate level, or clean air can be efficiently produced, and a comfortable living environment can be provided.

With the above configuration, the air purifying operation can be performed independently, the humidity of the living space can be maintained at an appropriate level, and clean air can be produced efficiently and continuously, so that a comfortable living environment can be provided.
