A sanitary device is comprised of a tank storing an amount of water, a water pressure source, a cylinder, a nozzle pipe slidably fitted in the cylinder such that across the nozzle pipe a base side chamber and a distal side chamber are defined in the cylinder, a return spring accommodated in the distal side chamber and urging the nozzle pipe toward the retracted position thereof, and a control device serving for establishing either a first fluid communication between the tank and the base side chamber or a second fluid communication between the tank and the distal side chamber in such a manner that the first fluid communication brings the nozzle pipe into its operating position for ejecting the water while the water pressure is being supplied to the tank and the second fluid communication, together with the return spring, brings the nozzle pipe into its retracted position.

Sanitary device

A sanitary device is comprised of a toilet bowl having therein an inner space and a rear portion, a casing mounted on the rear portion of the toilet bowl, an outer nozzle having at its front, intermediate and rear portions an opening, a tapered wall and an inlet, respectively, and secured to the casing in such a manner that the outer nozzle is oriented toward the inner space of the toilet bowl. A water supply device supplies an amount of water continuously to the inlet of the outer nozzle. An auxiliary valve is provided at a frontward portion of the tapered wall of the outer nozzle for interrupting the fluid communication between the atmosphere and the inside of the outer nozzle. An inner nozzle has holes top be aimed at a body part and disposed in the outer nozzle in such a manner that when the inner nozzle is in its retracted position, the fluid communication between the inlet and the inside of the outer nozzle is established, and when a retainer mounted of the rear portion of the inner nozzle is in engagement with the tapered wall, the extended position of the inner nozzle is established. A spring urges the inner nozzle in the direction of its retracted position and a valve is disposed in a rear portion of the inner nozzle so as to be opened only when the inner nozzle is in its retracted or extended position.

In a sanitary device of the bidet type, wherein the cleansing water is warmed in a hot water tank before being ejected for cleansing purpose, the improvement wherein at least a part of the cleansing mechanism is retractable within and extendable without said hot water tank so as to be warm when use thereof is initiated.
