Abstract

PURPOSE: To obtain hot water of a temperature as desired without supplying the hot water while maintaining the high temperature higher than required by connecting to communicate a feed water passage of the downstream side from pressure reducing means with mixing means via a bypass passage, mixing hot water in a hot water storage tank with the water from the bypass passage and supplying it to a hot water supply passage. CONSTITUTION: The hot water from a hot water storage tank is mixed with the water from a bypass passage 19 by a mixing valve 15, and the mixed water is supplied from a hot water supply cock 16 via a hot water supply passage 17. In this case, a supply hot water temperature thermistor 20 detects the temperature of the hot water after mixing, and if the detected temperature Ti is lower than the target temperature Ts set by the temperature set switch 31 of a controller C, a drive motor is operated to raise the elevation member of the valve 15, while if the detected temperature Ti is reversely higher than the target temperature Ts, the member is lowered to regulate it to the position corresponding to the target temperature Ts. Accordingly, the hot 'water of unexpectedly high temperature is not supplied, but the hot water of the temperature near as desired can be supplied.

Since the water from the bypass passage of the communication connection is mixed with the hot and cold water in the hot water storage tank and supplied to the hot water supply passage, the mixing ratio of the mixing means is adjusted within a predetermined range in advance. If this is done, the hot and cold water in the hot water storage tank will always be mixed with water at a predetermined mixing ratio to supply hot water, and there is the danger that hot water in the hot water storage tank will be directly supplied as in the past. Avoided. In this case, if the bypass passage for supplying water to the mixing means is simply connected to the water supply passage, when the water pressure in the water supply passage changes, the inside of the hot water tank supplied from the water supply passage via the pressure reducing means. The ratio between the water pressure in the hot water tank and the water pressure in the bypass channel fluctuates, and the water in the hot water tank is not always mixed at a predetermined mixing ratio. It doesn't mean that. In that respect, in the present invention, since the bypass passage for supplying water to the mixing means is connected to the water supply passage on the downstream side of the pressure reducing means arranged in the water supply passage, for example, the water pressure in the water supply passage varies. Even if it occurs, the ratio of the water pressure in the hot water storage tank supplied from the water supply channel to the water pressure in the bypass channel is maintained at a substantially constant level. It is possible to supply hot water at a temperature close to the temperature.
