Abstract: A human private parts washing apparatus according to this invention is provided with the following: a new washing water splashing means comprising a nozzle supporter, a washing nozzle and a washing water supply tube, which is extending in the washing nozzle in a manner with one end protruding in the washing nozzle, and supplies the washing water to the washing nozzle and makes up the washing nozzle advancement at the same time; a newly arranged washing nozzle driving means comprising a fixed rack formed on a nozzle supporter, a movable rack formed on a washing nozzle in a manner parallelly facing the fixed rack and a pinion meshing the fixed rack and the movable rack; a washing nozzle comprising an outer nozzle operated slidably back and forth with a washing nozzle driving means and an inner nozzle operated slidably with a hydraulic pressure of the supplied washing water; and an auxiliary washing nozzle driving means aiding a washing nozzle driving means to operate the washing nozzle over an additional stroke

Abstract: A human private parts washing apparatus is provided with a nozzle supporter, a washing nozzle and a washing water supply tube which extends in the washing nozzle with one end protruding into the washing nozzle. The washing nozzle includes an outer nozzle operated slidably back and forth by a washing nozzle driving device and an inner nozzle operated slidably by the hydraulic pressure of the supplied washing water. An auxiliary washing nozzle driving device operates the washing nozzle over an additional stroke. Thus, the washing water is supplied independent of the washing nozzle's operation positions. The washing nozzle reaches the bidet washing position ahead of the anus region washing position by 30 to 35 mm without any trouble, and the washing nozzle can be advanced and retracted by 10 to 30 mm additionally with respect to the bidet washing position.

Abstract: A shock-absorber is provided at a rear end portion of a toilet bowl is brought into operative engagement with a seat when inclination of the seat relative to an upper side of the toilet bowl becomes less than a set value. Thus, lowering or downward movement of the seat may be performed more quickly during the initial portion of the lowering movement prior to engagement with the shock absorber.

Abstract: A washing device for parts of body comprises a pump means to supply water from a water source under pressure and a nozzle means which spouts the pressurized water against the private parts of human body as a water jet. Since the pump means has an air intake port on the suction side, air foam is securely mixed in the water jet. Also, since an air control valve is provided in connection with the air intake port, the mixing ratio of the air in the water can be controlled by the air control valve.

Abstract: In a washing device for parts of human body including a first hollow piston with a nozzle at the front end thereof and a second hollow piston with a nozzle at the front end thereof; a drive means for said first and second pistons comprises a single drive motor, a rotatable member to be driven by said motor and a belt-like member one end of which is anchored to the first piston and the other end of which is anchored to the second piston; said belt-like member has a middle portion engaging the periphery of the rotatable member and a pressurized water supply means. As one aspect of the invention, the rotatable member rotates reversibly at a fixed position and transmits the driving force to the belt-like member so as to move selectively the first and second pistons and a retracted inoperative position. In this case, these first and second piston move in opposite directions each other.

Abstract: A circuit breaker for automatically interrupting the flow of an electric current from a power supply to a load such as a microcomputer before the load malfunctions so as to avoid an unexpected accident such as a fire. The circuit breaker includes a wire subject to erosion upon exposure to an acid atmosphere which will separate prior to the malfunction of the load to interrupt the flow of current to the load. Alternatively, the circuit breaker could include a mass of powdery material which expands upon exposure to an acid atmosphere to operate a switch to interrupt the flow of current.

Abstract: In a washing device for parts of body including first cylinder means comprising a first cylinder and a first piston to be operated in the front end direction thereof by introducing pressurized water onto the first cylinder and a second piston to be operated in the front end direction thereof by introducing pressurized water into the second cylinder; pressurized water control means for selectively supplying pressurized water to both of the first and second cylinders, or to any one of them; and pressurized water supply means for supplying pressurized water to the pressurized water control means: the washing device further including sensor means for sensing that any one of the first and second pistons is operated over a predetermined operating position in the front end direction thereof.

Abstract: A sanitary cleansing spraying device for use in toilets which includes a retractable spray nozzle connected through a control valve with a heated water reservoir which is in turn connected with a submerged water pump in the flushing water tank. The control valve and the spray nozzle are connected with a flushing lever so that the control valve is opened and the spray nozzle is moved to a spray position. The spray nozzle has two spray positions and in one of the two positions water is sprayed with a lower pressure than in the other position so that the device can be used as a bidet.
