うにすればよい。When supplying hot water to the bathtub (1), the pump (7) is driven to supply hot water from the hopper (10) to the bathtub (1), filling the circulation pipe (6) with hot water in advance. This is to remove air from the circulation pipe and accurately detect water pressure. Next, in the case shown in Fig. 2, the on-off valve (11) is opened to heat the hot water heat exchanger (4) and the pump (7) is heated.
) to supply hot water to the bathtub (1) via the three-way valve (12), pump (7), heat exchanger (5), and bathtub connector (2). As hot water continues to be supplied, the water level in the bathtub rises, and the water head pressure changes according to the water level in the bathtub. Since a part of the circulation pipe from the water pressure detection part (8) to the bathtub (1) is used as a pressure detection pipe (9), changes in the water head pressure are detected through the pressure detection part (8) through the pressure detection pipe (9). ). This pressure change may be converted into an electrical signal to close the R closing valve (11) with a constant output.
