Abstract

An anal region rinsing system comprises an egress pipe (26) having a rinsing tube (30) connected perpendicularly therewith, a lever (29) on a first end of the egress pipe, a control valve (16) on a second end of the pipe, and a water heater (13) supplying water to pipe (26) via the control valve. The egress pipe is rotatingly and slidingly retained under the rear portion of a lavatory seat by two axle holders (20, 21) secured thereon and biased by a spring (28). Water from an external supply enters the water heater via a T-shaped pipe (11) connected also to a water tank. In operation, the rinsing tube is slid out of a guard (32) between the axle holders and rotated upwards so that water ejecting from a nozzle (31) on the end of the rinsing tube under the control of valve (16) is directed onto the anal region of a user.

Description

DESCRIPTION
Title
An Anal Region Rinsing System
Technical Field
The present invention relates to rinsing systems, and more particularly to a rinsing system which is specifically designed for cleansing the anal region of a user after defecation.
Background Art
After defecation, the anal region is usually cleaned by toilet paper or water rinsing. However, using toilet paper to wipe clean the anal region may lead to contamination of the hands. Further, the disposal of the toilet paper is problematical as storage in a trash bin could prove unsanitary and wasteful of space, while flushing of the toilet paper could clog the bowl. A variety of anal region rinsing systems employing spray nozzles have been designed to eliminate this problem, however, they tend to be of considerable expense as their mechanisms generally require modification of the entire lavatory bowl to accommodate the integral spray nozzles. Furthermore, the spray nozzles of the aforementioned prior art rinsing systems generally are at a fixed angular orientation so as to be inconvenient to a user requiring him or her to perform various motions to align their anal region with the ensuing water jet.
Disclosure of the Invention
The present invention has been accomplished in order to overcome the aforesaid disadvantages of the prior art rinsing systems. It is therefore an object of the present invention to provide an anal region rinsing system which is inexpensive to manufacture and easy to assemble. It is another object of the present invention to provide an anal region rinsing system which is easy to operate. It is still another object of the present invention to provide an anal region rinsing system which can be conveniently adjusted to allow the spray nozzles thereof to be accurately aimed at the anal region. It is still another object of the present invention to provide an anal region rinsing system which has means to protect the spray nozzle thereof against contamination when not in use. It is still another object of the present invention to provide an anal region rinsing system which has means to automatically move the spray nozzle thereof into a guard for protection after each use.

Best Mode for Carrying Out the Invention
Referring to the annexed drawings in detail, there is provided a generally T-shaped pipe 11 having a first end connected to a water supply, a second end connected to a water tank 10, and a third end connected to the inlet port of an electric water heater 13. The electric water heater 13 has an outlet port connected to a pressure reducing pipe 14 through a hose 12. The pressure reducing pipe 14 comprises a narrow conduit 15 having a first end connected to the hose 12 and an opposite end connected to a control valve 16. Below the water tank 10, there is provided a lavatory bowl 17, in which a lavatory seat 18 is pivotably disposed thereabove. The lavatory seat 18 includes two axle holders 20,21 spacedly disposed along the rim of the rear portion 19 thereof. The axle holders 20,21 each have an inwardly directed hinge pin 23 on an inner side by which a lavatory cover 24 is pivotably attached, and a holder lug 25 pressed against the underside of the rear portion 19 for holding a water egress pipe 26. Two locating rings 27 are respectively mounted on the two opposite ends of the water egress pipe 26 near the axle holders 20,21. The water egress pipe 26 has a first end connected to the control valve 16, and an opposite end coupled with a lever 29. A torsion spring 28 is sleeved onto the water egress pipe 26 with a first end being secured to a first axle holder 21 and an opposite end being secured to the outlet pipe near lever 29. A rinsing tube 30 is connected perpendicularly to the water egress pipe 26 at a medial location, with the nozzle aperture 31 thereof projecting downward into the hollow of the lavatory bowl 17. Rotating the lever 29 causes the water egress pipe 26 to rotate about the axle holders 20,21 and thereby adjust the angular position of the rinsing tube 30. When the lever 29 is disposed in the horizontal position, the rinsing tube 30 projects obliquely downward through roughly a 45 degree angle. On the bottom of the rear portion 19 of the lavatory seat there is provided a depending guard 32 adjacent the rinsing tube 30. The guard 32 has a sloping edge (not shown), by which the rinsing tube 30 is guided into a holding space defined therein when the rinsing tube 30 is turned downwards.
The operation of the present invention is outlined hereinafter. By pulling the lever 29 laterally outwards the rinsing tube 30 is moved out of the guard 32. Once the locating ring 27 comes into abutment with the first axle holder 20, the lever 29 is turned to a horizontal position to bring the rinsing tube 30 to a 45 degree angle orientation with the end thereof projecting into the lavatory bowl 17. Whereat, the nozzle 31 of the rinsing tube 30 is aimed at a user's anal region. After cleansing, the control valve 16 is closed. The lever 29 is released so as to permit the water egress pipe 26 to move back under the bias of the return spring 28. The lever 29 is then rotated backwards to cause the nozzle tube 30 to return into the holding space inside the guard 32. Once the rinsing tube 30 has been moved into the guard 32, the other locating ring 27, comes into abutment with the second axle holder 21. In cold weather, the electric heater 13 may be turned on to heat the water which is to be delivered to the water egress pipe 26 so as to increase user comfort. Further, the narrow conduit 15 of the pressure reducing pipe 14 is dimensioned in accordance with local water pressure, if the water pressure surpasses a predetermined level, the ingress of water will be hindered to reduce its pressure while passing through the conduit 15 of the pressure reducing pipe 14. Thus, the water which is ejected through the nozzle 31 will not be excessively forceful for the anal region.
