<P>PROBLEM TO BE SOLVED: To stabilize the hot-water temperature of a mist sauna bath used with a hot-water storage type hot water supply device. <P>SOLUTION: This hot water storage type hot water supply device comprises a hot-water storage tank for storing hot water, in which a water supply pipe and a water discharge pipe are connected, a heat source for heating the hot-water stored in the hot water storage tank, a supplied water sensor provided in the water supply pipe to detect the supplied water temperature T2, a check valve, a control device for controlling boil-up of the stored hot water and the supplied hot water temperature, a mixing adjuster, a flow rate sensor and a supplied hot water temperature sensor. A mixing adjuster control means is provided to change a starting flow rate and a stop flow rate in the feedback control of the mixing adjuster corresponding to a hot water flow rate Q, which is detected by a flow rate sensor, by estimating the hot water flow rate from the hot-water discharge pipe based on the stored hot water temperature T1 detected by the stored hot water sensor, the supplied water temperature T2 detected by the supplied water temperature sensor, the supplied hot water temperature T3 detected by the supplied hot water temperature sensor and the supplied hot water flow rate Q detected by the flow rate sensor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
