Abstract

PURPOSE:To make it easy to operate hot and cold water mixing device, by driving and adjusting a mixing valve as the temperature detected by a thermister becomes the same as the preset temperature, and performing the slide operation of the lever of a selector valve. CONSTITUTION:When a desired temperature is set by the switch-operation of a setting unit 20, the temperature of the mixed water is adjusted by a controller 21. Switching the flow of water from a faucet 30 to a shower nozzle 32, or from the shower nozzle 32 to the faucet 30, and stopping the flow of water, are performed by the sliding operation in a selector valve 27, through varying the opening part formed in one valve body 25 out of valve bodies 24-26, to which a selector 28 is connected. In this way, the operation of the hot and cold water mixing device can be performed light, by a slight power.
