PURPOSE:To obtain mixture water of set temperature automatically by comparing a temperature sensed by a temperature sensing sensor provided on a mixture water path with a set temperature and controlling the opening ratio of a water valve and a hot water valve. CONSTITUTION:Drive units 5 having motors 6 which can vary opening ratio are provided on a water valve 2 and a hot water valve 4, and a temperature sensing sensor 8 is provided on a mixture water path 7 to which a water path 1 and a hot water path 3 are communicated. An electric signal received from the temperature sensing sensor 8 is compared with a set temperature, and a working signal comparing the temperature difference and adjusting the opening ratio of the water valve 2 and the hot water valve 4 is fed to drive units 5 and the temperature of the mixture water is controlled.
