The large airflow exchanges heat with the fins 63 cooled by the endothermic action of the second heat exchange surface 62a of the thermoelectric conversion element 62, becomes cold air, blows through the duct 60, and is discharged toward the feet. At this time, the three-way valve 12 connects the water supply pipe 10b and the water supply pipe 10d, and the tap water supplied from the tap water pressure source is used only for cooling the heat generating surface of the thermoelectric conversion element 62, and the drainage water is discharged. It is supposed to be done. Thus, the washed and wet feet are cooled and dried. When a predetermined time elapses, the energization of the sirocco fan 61 and the thermoelectric conversion element 62 is stopped, the massage process ends, and the automatic process ends one way.

In the above operation, the automatic process has been described. However, when a switch for instructing the operation of each of the cleaning switch 73, the massage switch 74, the drying switch 75, etc. is pressed, the cleaning process, the massage process or the blowing ( The drying process is performed in a single step. Further, in the case of a massage process during an automatic process or a massage process by the massage switch 74, the washing bath 4 can be removed and massage can be performed on the dry massage table 3. In particular, in the case of the massage process by the massage switch 74, the massage can be performed on the dry massage table 3 without getting the feet wet, and the massage can be performed while wearing socks or the like.

When the room temperature is selected by the air temperature changeover switch 80, the thermoelectric conversion element 62 is not energized. When warm air is selected, the thermoelectric conversion element 62 is not energized, but the heater 69 arranged in the duct 60 is energized so that the air flow becomes warm air. ing. Further, if it is desired to interrupt the above-mentioned operation on the way, it can be interrupted by pressing the stop switch 78. When the stop switch 78 is turned on, the control device 90 returns all the driving devices to the initial state. For example, when water is being supplied, the water supply is stopped, the drain valve 14 is opened, and the cleaning water in the cleaning container 4 is drained. The motor 41 is stopped when the massage is being performed.

Further, although not described in the automatic process,
In this embodiment, water can be injected in the washing process and the rinsing process. Water injection can be instructed by pressing the water injection switch 82 of the operation panel 71, and when the water injection switch 82 is pressed, the three-way valve 12 causes the water supply pipe 10b and the water supply pipe 10c.
