Claims (1)

[Scope of utility model registration request] a cleaning nozzle provided on a side wall of the bathtub and spraying a cleaning liquid onto the inner wall surface of the bathtub; a circulation pipe incorporating a pump that collects the cleaning liquid sprayed from the cleaning nozzle from the bottom side of the bathtub and circulates it to the cleaning nozzle;
a heater built into the circulation pipe to heat the circulating fluid; a return pipe opening/closing valve provided in the circulation pipe at a position upstream of the flow of the circulating fluid from the heater;
A water supply pipe connected to the circulation pipe between the return pipe on-off valve and the heater, a temperature sensor provided on the inlet and outlet sides of the heater, and a flow rate sensor that detects the flow rate of water flowing through the water supply pipe. Then, upon receiving the detection signals from the temperature sensor and flow rate sensor, the operation of the heater, pump, and return pipe opening/closing valve is controlled according to a given program to control cleaning operation, hot water filling operation, and reheating operation. A fully automatic bath pot with a cleaning function and a control device.
