CONSTITUTION:A control part is coupled to driving parts 5 and 5, receives an electrical signal from a temperature sensor 8, compares it with the set temperature, sends an operating signal for adjusting a ratio of a degree of opening of water valve 2 and a hot water valve 4 to the same temperature as the desired temperature to the driving part, the ratio of a degree of opening of the water valve 2 and the hot water valve 4 is adjusted through both driving parts 5 so as to enable a temperature of mixed water to be automatically controlled to the desired temperature. When the temperature of the water is sensed by a temperature sensor 8 arranged in a mixture water passage 7 and the temperature of the mixture water is different from the predetermined temperature, the adjusting valve is opened to discharge the mixture water, the temperature of the mixture water is adjusted to the desired temperature in the mixture water passage and the hot water at the desired temperature can be instantly supplied. Therefore, opening of the adjusting valve causes the hot water of desired temperature to be rapidly supplied.

湯装置に構成したので次のような効果がある。(Effects) As described above, the present invention provides a water heater equipped with a thermostatic mixing valve, in which a temperature-sensitive sensor is provided in the mixing channel to sense the temperature of the mixed water in the channel and convert the detected temperature into an electrical signal. The opening/closing valve is provided with a driving part that drives the opening/closing valve, and the driving part and the temperature sensor compare the electric signal received from the temperature sensor with an electrically settable set temperature. A control unit that can control the operation by sending an operating signal to the drive unit to open the closed valve to discharge the mixed water and adjust the temperature of the mixed water in the mixing channel to the set temperature when the temperature of the mixed water inside and outside differs from the set temperature Since the hot water supply device is constructed by connecting the two, it has the following effects.

開閉弁を開くと設定温度の湯が即座に供給され、冷めた
湯を捨てる必要が無く使い勝手がよい。When you open the on-off valve, hot water at the set temperature is immediately supplied, and there is no need to throw away cold water, making it easy to use.

湯を流しっばなしにしないで最小限しか捨てないので無
駄が少なく経済的である。It is economical because there is little waste because only the minimum amount of hot water is thrown away without leaving the hot water in the sink.

依って所期の目的を達する。Thus, the desired goal is achieved.
