水抜け防止装置。 In order to separate the tap water from the bathtub water, a cutting device that injects air into the pipe except when water is flowing is installed in the pipe leading to the bathtub or in the hot water pouring pipe connecting the circulation reheating pipe and the hot water supply pipe. In an automatic bath pot in which the water level of the bathtub is detected by a pressure sensor, atmospheric pressure and A negative pressure stop valve is provided that opens and closes based on the difference between the force set by the spring and the force that moves the valve body due to the pressure in the pipe, and the negative pressure stop valve is closed when water flow ends. A water drain prevention device for an automatic bath pot, characterized by blocking air from flowing into a pipe line leading from an edge cutting device to a bathtub or a circulation reheating pipe line.
