PURPOSE:To obtain hot water of a high temperature in a short time and also hot and cold water mixture at a variable mixing rate in the hot water supplying device having a hot water tank by providing a single switching valve to constitute a circulation circuit between a separately provided heating tank and a hot and cold water mixing circuit. CONSTITUTION:The hot water supplying device comprises the hot water tank 1, the heating tank 8 and the switching valve A, the valve member 5 which is connected to a water supply pipe 4, a hot water tank supply port 3, a hot water supply pipe 7, an axiliary hot water supply pipe 11 and a hot water supply port 2 respectively. In order to supply water to the hot water tank, another valve member of the switch valve A is switched in the direction (a), and after the water introduction is confirmed, switched in the direction (c) so as to form the circulation circuit. Then, power is supplied to a heater 9 so as to perform a quick heating to heat the water within the hot water tank 1 by the convection heating. In order to mix the hot and cold water, the valve member 6 is directed in the direction (b). The temperature of the mixture thus obtained can be changed arbitrarily by adjusting the opening ratio of the valve member 6. |
