Abstract
A washing device for parts of human body comprises a thermostatic mixing valve which is disposed at a junction of a cold water supply passage and a heated water supply passage, a latching solenoid valve which is mounted on a heated water drainage passage branched out from said heated water supply passage and a latching solenoid valve which is mounted on a mixed hot water supply passage. Due to such construction, electric power for heating water is no longer necessary in the toilet bowl and electric power for mixing heated water and cold water to produce mixed hot water to be ejected from an ejecting nozzle also becomes unnecessary. Furthermore, electric power for operating the solenoid valve is minimized by means of a latching solenoid. Accordingly, the overall consumption of electric power necessary for operating and controlling the washing device can be minimized thus enabling the use of a small dry cell or battery as an electric power source of the washing device.
