<P>PROBLEM TO BE SOLVED: To provide a hot water storage type hot water supply bath device preventing freezing of a bath circulation circuit and enabling comfortable bathing. <P>SOLUTION: The hot water supply bath device is provided with a heating means 2 and a hot water storage tank 1. A water feed pipe 7 is connected to the lower part of the hot water storage tank 1 and a hot water discharge pipe 8 is connected to the upper part of the hot water storage tank 1. The hot water supply bath device is further provided with a bath circulating pump 18 for circulating bathtub water in the bath circulation circuit 16; a bath temperature sensor 20 for detecting the temperature of bathtub water; a water level detection means 21 for detecting a water level of a bathtub 3; a bypass pipe 22 for bypassing a bath heat exchanger 17; and an opening/closing means 23 for switching opening/closing of the bypass pipe 22 side and the bath heat exchanger 17 side. During freezing prevention operation for driving the bath circulating pump 18 and circulating bathtub water by detecting freezing danger temperature by the bath temperature sensor 20, when the water level detection means 21 detects a person taking a bath, the freezing prevention operation is stopped or suppressed, so as to enable freezing prevention and comfortable bathing. <P>COPYRIGHT: (C)2010,JPO&INPIT |
