This will be described with reference to FIG. As shown in the figure, the main body 1 is placed and fixed on a toilet bowl 2,
A heating means 9 comprising a drying means 4, a hot water tank 6 having a hot water heater 5 therein, and a cleaning nozzle 7a connected to the hot water tank 6 in a watertight manner, and a control unit 8;
The toilet lid 10 is rotatably attached to the main body 1. The heating means 11 is provided inside the toilet lid 10,
The hot air outlet 12 is attached to the side of the toilet lid 10. The deodorizing means 3 includes a deodorizing suction opening 13 opened in the bowl 2a of the toilet bowl, a deodorizing blowout opening 14 opened in the side surface 1a of the main body 1, and a deodorizing suction opening 13 and a deodorizing blowout opening 14 in the main body 1. An air passage 15 is provided.
A deodorizing agent 16 that removes odor by adsorbing and decomposing a compound such as ammonia generated from filth and a suction fan / motor 17 are provided in the deodorizing inlet 13 from the deodorizing suction port 13. The drying means 4 includes a dry suction port 18 opened in the rear surface 1b of the main body 1, a dry blowout port 19 opened in the bowl 2a of the toilet bowl, and a dry wind connecting the dry suction port 18 and the dry blowout port 19 in the main body 1. The drying air passage 20 has a room temperature sensor 21 from the drying suction port 18.
And a fan motor 22 for drying and a heater 23 for drying. The control unit 8 periodically (every 5 to 6 minutes) fetches a signal from the room temperature sensor 21 and controls the amount of electricity supplied to the heating unit 11 based on the signal level. And
Before capturing this signal, when the drying fan motor 22 is off, the drying fan motor 22 is turned on and rotated at a lower speed than during drying, and after capturing the signal,
The drying fan motor 22 is turned off.

The operation of the above embodiment will be described. When the control unit 8 takes in the signal from the room temperature sensor 21, the air in the room with the toilet passes through the room temperature sensor 21 from the drying suction port 18, is pressurized by the drying fan motor 22, and is not energized. The air is discharged from the drying outlet 19 into the bowl 2a of the toilet bowl through the nozzle 23.

As described above, according to the sanitary washing apparatus of the embodiment of the present invention, the room temperature sensor 21 senses the air in the room where the toilet is located by the drying fan motor 22 when the temperature is detected. 6 and is hardly affected by other heat sources such as the drying heater 23. When the room temperature is adjusted, the time delay and the temperature difference between the temperature in the room where the toilet is located and the ambient temperature of the room temperature sensor 21 are small. Since the control of the amount of power supply to 11 is performed appropriately, the temperature in the room where the toilet is located can be stably maintained at the set temperature. In addition, since the time delay and the temperature difference between the water temperature in the bowl 2a of the toilet and the ambient temperature of the room temperature sensor 21 are small during the prevention of freezing, the amount of electricity supplied to the heating means 11 is appropriately controlled. Of the water in the ball 2a can be reliably prevented.
