Abstract: A washing device for parts of human body for use in a flush toilet which includes essentially a cylinder, a shaft and a water tank. The cylinder has a water supplying orifice and incorporates the shaft in the bore formed therein. The shaft comprises a shaft body and a control axis which is coaxially mounted in the bore of the shaft body. The shaft body has, at one end, a water spouting nozzle and an inflow orifice communicating a water passage to the water inlet port of the cylinder, and has, at the other end, a lever to rotate the whole shaft body. By operation of the lever, water spouting nozzle is movable to or from its inoperative rest position. An amount of washing water to be spouted is controlled by adjusting a sectional area of the water passage. This adjustment is effected by axial movement of the control axis which is provided with a tapered valve portion at one end and is provided with one operating knob at the other end thereof. The knob protrudes from one extremity of the shaft body.

Abstract: A sanitary spray device of the type having a nozzle adapted to extend into a toilet bowl for spraying and washing fluid on the private parts of a person seated on the toilet bowl is provided with a rotatable valve in association with a liquid supply tank. The nozzle is secured to the rotatable valve and is comprised of an outer pipe and an inner concentrically spaced pipe defining inner and outer liquid passages.

Abstract: A device for washing the posterior parts of the human body includes an electrically operated driving means which moves a nozzle means certainly either to a first position for washing the anal area or to a second position for washing the female genitals, independently of the hydraulic pressure used. The nozzle means can be shifted forward or backward from the first or second position within a given range according to the instruction from the user.

Abstract: An appliance for washing the posterior parts of the human body with water is equipped with an outer nozzle and an inner nozzle that is rotatable inside the outer nozzle. The outer nozzle is provided with holes, while the inner nozzle is formed with a plurality of sets of holes. Any desired one set of the sets of holes in the inner nozzle can be brought into registry with the holes in the outer nozzle by rotating the inner nozzle, whereby the area through which washing water is spurted can be varied.
