Abstract: A washing device for parts of human body being such as anus or private part of female is disclosed. Such washing device is substantially characterized in that the heated-water supply source and the cold-water supply source which are connected with a heated-and-cold-water mixing valve respectively are both installed outside of a toilet chamber or a bathroom and a mixed-water ejecting nozzle is connected to a downstream end of a mixed-water supply passage which has an upper end thereof connected to an outlet opening of the heated-and-cold-water mixing valve. Due to such construction, the washing deivce can extremely improve the heating efficiency so as to enable the considerable energy saving and can unnecessitate the installation of the heat exchangers in the washing device so as to make full use of a narrow space of a toilet chamber or a bathroom.

Abstract: A faucet for mixing hot and cold water includes a valve casing, cold and hot water inlet pipes coupled to the valve casing, first and second outlet pipes coupled to the valve casing, a valve housed in the valve casing and having a fixed plate and a movable plate, and an actuator for angularly moving the movable plate. The fixed plate has at least one cold water passage hole communicating with the cold water inlet pipe, at least one hot water passage hole communicating with the hot water inlet pipe, a first outlet hole communicating with the first outlet pipe, and a second outlet hole communicating with the second outlet pipe. The movable plate is held rotatably slidably against the fixed plate in watertight relation and has a recess defined in the surface thereof slidably contacting the fixed plate. When the movable plate is angularly moved by the actuator, at least one of the cold and hot water passage holes is brought into selective communication with the first and second outlet holes through the recess.

Abstract: Hot water supply temperature is set by a temperature setting device in response to an instantaneous flow rate signal from a water flow rate sensor arranged in a water supply pipe and a feeding water temperature signal from a feeding water temperature sensor which are compared with a predetermined hot water supply temperature and calculated in a control unit. A proportional valve and other devices in a gas supply pipe are controlled in response to the result of the comparison and calculation to define a required volume of gas for ignition and heating. At the same time, a fan damper is controlled by a damper control device so as to adjust the volume of combustion air. A signal representing discharging hot water temperature from a discharging hot water temperature sensor arranged in a hot water feeding pipe is fed back to the control unit and calculated therein, and a valve in the hot water supply pipe is adjusted in response to the result of calculation to attain the desired hot water supply temperature.
