PURPOSE:To effectively prevent mixture of the air to a circulating passage for bath temperature keeping function or invasion of hot water from a bathtub to a hot water supply passage side with a low cost without necessity of a three- way switching valve, etc., for connecting the hot water supply passage to the circulating passage for the bath temperature keeping function and particularly to facilitate draining in the case of an antifreezing operation. CONSTITUTION:The separating valve device for supplying bath drop-in hot water comprises a hot water supply valve 91, a first hot water supply check valve 92, an overflow chamber 93, a reinforced check valve 94, and a first air charge valve 96a for switching an air charge port 93a of the chamber 93. Further, the device comprises at least a vacuum breaker 99 provided in a hot water supply passage 51 before the valve 91, and valve forcible moving means 98 for forcibly operating the valve 94 and the valve 96a, and a controller 80 for forcibly setting the valves 96a and 94 to half-opened states by the means 98 when an antifreezing operation is instructed. |
