To enable power saving by detecting temperature increase of washing water in a washing water tank due to a condenser to be used for hot water washing, and in addition, circulating high temperature washing water by a pipe to insulate a hot water tank, a nozzle, a stool seat or the like.
A cooling device comprising a condenser 5, a compressor, an evaporator and the like together with a washing tank 4 and a hot water tank 11 is incorporated in a cover vertically provided rearward of a stool, and the condenser 5 is immersed in the washing tank 4 to be cooled. When temperature increase of washing water in the washing tank 4 is detected with a temperature sensor 13, a valve 15 is automatically opened to jet the high temperature washing water of the washing tank 4 together with hot water of the hot water tank 11 from nozzles 12a, 12b during washing. In addition, a hot water pipe is connected to the washing tank 4 to circulate the high temperature washing water by a circulation pump, and the hot water tank 11 the nozzles 12a, 12b, a stool seat, a hot wind blowing device and the like may be insulated. Thereby temperature increase of washing water is effectively utilized to obtain power saving effect.
