Claims (1)

[Scope of Claim for Utility Model Registration] A reheating heat exchanger connected to a bathtub through a circulation pipe, and a water supply pipe connected to the reheating heat exchanger and equipped with a hot water filling on/off valve, a water flow sensor, and a temperature sensor. and a hot water heat exchanger that heats the hot water pipe and has a gas proportional control valve and a gas solenoid valve that operate according to a command from a remote device. If the hot water outlet temperature exceeds the hot water filling set temperature even after reducing the gas amount to the allowable minimum, calculate the amount of heat required to heat the hot water to the hot water filling set temperature when water at the inlet temperature is supplied to the hot water filling set amount. and supplying the necessary amount of heat during the filling of the hot water based on the calculation of the said amount of heat calculating means, stopping the operation of the hot water supply heat exchanger after supplying the necessary amount of heat, and setting the hot water filling at the water input temperature. An automatic bath device characterized by comprising: a hot water temperature control means for supplying water up to the specified amount;
