Then, the air sucked from the suction port 3 is warmed by the heat exchanger 11 and blown out from the outlet 4.

When the bathroom cleaning mode is selected, tap water supplied from the water supply port 14 to the plate heat exchanger 12 is supplied to the electrolytic cell 13, and electrolyzed water having a high free chlorine concentration is generated. Then, the electrolyzed water is supplied to the nozzle unit 5 via the solenoid valve 15 for nozzles, and is sprayed from each nozzle 18a to 18g of the nozzle unit 5 toward the wall surface and the floor surface.

When the high-speed cleaning mode is selected, hot water is supplied from the external boiler device to the plate heat exchanger 12 via the solenoid valve 26 for the plate heat exchanger.

As a result, the free chlorine concentration of the electrolyzed water generated in the electrolytic cell 13 becomes higher, and the electrolyzed water is supplied to the nozzle unit 5.

When electrolyzed water is sprayed into the bathroom, germs and mold adhering to the walls and floor of the bathroom are washed away. Then, after the electrolyzed water is sprayed for a preset time, the water is sprayed for a certain period of time, then the mode shifts to the drying mode, and warm air is blown from the outlet 4 to dry the inside of the bathroom.
The spraying time here is experimentally stored in the control unit 19 using various germs and molds that inhabit the bathroom and the like in advance. For example, when the temperature of the electrolyzed water detected by the mist sensor 27 is 20 ° C., the free chlorine concentration of the electrolyzed water generated in the electrolytic cell 13 is about 1 to 2 ppm, so that germs and molds can be washed away. Needs spraying for 10 minutes or more, and the electrolyzed water spraying time t1 is stored as 10 minutes or more, for example, 12 minutes. As described above, the electrolyzed water spraying time t1 is changed in advance according to the temperature of the electrolyzed water so that a sufficient effect can be obtained to wash away bacteria and mold even when the temperature of the electrolyzed water changes.

When the mist generation mode is selected, hot water is supplied from the external boiler device to the plate heat exchanger 12 via the solenoid valve 26 for the plate heat exchanger. Then, in the plate heat exchanger 12, heat is exchanged between the hot water supplied from the external boiler device and the tap water supplied from the water supply port 14, and the temperature of the tap water is raised so that the electromagnetic wave for the nozzle is used. Hot water is supplied to the nozzle unit 5 via the valve 15. Then, mist is sprayed from each nozzle 18a to 18g of the nozzle unit 5, and the bathroom can be used as a mist sauna room.

When the ventilation mode is selected, the ventilation damper motor 28 operates under the control of the control unit 19, and the suction port 3 communicates with the ventilation fan device 7. Then, the ventilation fan device 7 is activated, and the air in the bathroom sucked from the suction port 3 is discharged to the outside.
