ABSTRACT:
A compact and inexpensive hot-water washing apparatus for personal hygiene which is used for washing the anus or the like after depositing stool in a toilet. By the rotation of an operation shaft 41, the start switch 42 of a pump 27, a flow control valve 30 and an operating valve 35 interlock. The control of the flow rate of the hot water to be supplied to a nozzle 4 for washing the anus or the like and the use of an inexpensive non-self priming pump are enabled by providing a water passage through which the water sucked in from a low level cistern 6 is discharged into a hot-water tank 25 through the operating valve 35 by the pump 27, and a water passage for returning the hot water or water in the hot-water tank 25 through the flow control valve 30 to the suction port 34 of the pump 27. The action of a heat equalizing plate 52 prolongs the duration of hot water jetting of an optimum temperature.
