Both ends of the washroom ventilation operation switch 8D, the toilet ventilation operation switch 8E and the bathroom ventilation operation switch 8F are connected to the control device 16, and the washroom operation switch 8A, the toilet operation switch 8B and the bathroom operation switch are provided. The operation switch 8C is signal-connected to the control unit 16, and the toilet ventilation motor relay 17, the toilet ventilation motor relay 18 and the bathroom ventilation motor relay 19 are similarly controlled. Is connected to the signal.

Next, the operation will be described. First, when the operation switch 8A of the washroom is turned on, the ON signal is sent to the control device 16 and the relay 17 for the washroom ventilation motor is released.
Is closed, the ventilation motor 11A in the washroom is first operated to perform ventilation, and at the same time, the damper motor 4A in the washroom is operated to open the damper to open the chamber for the blowout body.
4 and the air-conditioning duct 6 are communicated with each other, the compressor / fan motor relay 15 is closed, and the indoor fan motor 2A, the compressor 9A and the outdoor fan motor 9B are operated, so that the blowout grill 7 in the washroom is opened.

Similarly, the bathroom ventilation motor 13A is first operated to provide ventilation. At the same time, the motor 4C for the damper in the bathroom is operated to open the damper and the chamber for the blowout main body.
4 and the air conditioning duct 6 communicate with each other, and the outlet grill 7 in the bathroom
Blow cold or warm air through.

If there is no generation of steam in the washroom and there is no need for ventilation operation, the washroom ventilation operation switch 8D is closed (ON), and the signal is sent to the control unit 16 for washroom ventilation. The motor relay 17 is opened, and the operation of the washroom ventilation motor 11A is stopped. In addition, when there is no odor in the toilet and ventilation operation is not required, if the toilet ventilation operation switch 8E is closed (ON), the signal is sent to the control device 16 for the toilet ventilation motor. The relay 18 is opened and the operation of the toilet ventilation motor 12A is stopped. Similarly, when no steam is generated in the bathroom and ventilation operation is not required, the signal is sent to the control device 16 when the bathroom ventilation operation switch 8F is closed (ON), and is used for the bathroom ventilation motor. The relay 19 is opened, and the operation of the bathroom ventilation motor 13A is stopped.

As described above, according to the first embodiment, when the operation switches of the toilet, the toilet and the bathroom of the remote controller 8 of the air conditioner 1 are turned on, the ventilation devices of the turned-on rooms are simultaneously operated. If ventilation is not necessary, only the ventilation operation can be stopped by turning on the ventilation switches 8D, 8E, 8F. In addition, if the ventilation performance of the ventilation device in each room is set to be equal to or more than the amount of air blown to each room of the air conditioner 1 during ventilation operation, the indoor static pressure becomes positive due to the air blown from the blowout grill 7 during air conditioning operation.
