Benefits of technology

[0023]The present invention provides a bidet assembly for retrofitting toilets of all sizes and shapes to provide clean fine jet stream of water for the cleansing of a user's private parts while keeping water from splashing out of a toilet bowl without the use of any controlling devices. The bidet assembly of this invention comprises a nozzle, preferably connected to a multi-port fitting which is connected to a water supply tube and a non-permanent mounting means for holding said nozzle inside a toilet bowl, preferably at the bowl's lip vertical surface or under the bowl's lip horizontal surface. Said strategic placement of said nozzle keeps the jet stream of water within the bowl inner chamber (below its lip) and prevents water from splashing out. The bidet assembly of this invention is easily installed within the confines of a toilet tank and bowl, with most of its parts not visible, therefore it is not unsightly.

Problems solved by technology

Therefore, said adjustable nozzle also obviates the need and expense of a control valve found in many prior arts to control water pressure for keeping water jet stream from shooting out of a toilet.

example 1

[0163]The dimensions used for an actual sample toilet bowl are: A=17.75″, B=13.5″ (FIG. 5). These are the dimensions for the elliptical shape of a toilet bowl rear lip's corner edge 7. A straight steel threaded rod having size 10-24 and 0.192″ in diameter (made by Steel Works), purchased from Lowe's Home Improvement, was used for this experiment. A 22.6″ length, which is half the calculated-circumference, was used to wedge at the rear end of said bowl (FIG. 18). An equal length from each end of said threaded rod was progressively cut and reinstalled to check for holding power until said rod could no longer stay up on the bowl surface. The results are shown in the following table:

LENGTH CUTFINALHOLDING ONTOFROM EACH ENDLENGTHBOWL SURFACEStart length22.6″YES1.0″20.6″YES0.5″19.6″YES0.5″18.6″YES0.5″17.6″YES1.0″15.6″YES1.0″13.6″NO

The minimum length is calculated taking 13.6″ divided by the circumference of 45.2″ and is equaled to 30.0%.

example 2

[0164]FIG. 32 shows two ellipses representing an actual toilet bowl opening (smaller elliptical shape) and the bowl's lip underside rear corner edge 7 (larger elliptical shape). Said larger elliptical shape of lip's underside rear corner edge 7 obviously can not be seen visibly and is drawn from measured values. In order to insert a long and stiff member into the inside surface of the larger elliptical shape of said bowl, the long and stiff member must first pass through the small bowl opening and this requires minimally bending it as represented by member 75. After passing through the bowl's opening, the ends are released and are restraint by the inside surface represented by the larger ellipse. Said long and stiff member would assume the position of member 76 after its release, assuming that it has enough spring-back property to reach this position represented by H2=7.900″. If the member has higher spring-back property, it would still be restraint but it would have a built-in flex...

example 3

[0165]In this example, the preferred embodiment example of an integral long and slender member bidet assembly of this present invention shown in FIG. 28 was fabricated using only common commercially available tools and merchandise to demonstrate low manufacturing cost. Said bidet assembly was fabricated using: ¼″ OD and 0.218″ ID 304 stainless steel tubing, ¼″ ID and ⅜″ OD PVC (polyvinyl chloride) clear flexible tubing, and quick connect (push-to-connect) ¼″ OD tube “T” fittings (Watts, North Andover, Mass.)

[0166]The objectives of quick and easy installation in this present invention of a bidet assembly is demonstrated by timing the speed to install and to remove said fabricated bidet assembly from a toilet. A total of five trials of installation and removal were done. It is assumed that a user would first read an installation instruction prior to actual installation. Therefore, the recorded time is the actual time to install and remove, not counting the time to read the instruction...

Abstract

A bidet assembly comprises at least one jet nozzle, connected to a multi-port tube fitting, which is connected to a water supply tube, which may comprise of four sections, and which is connected to the toilet bowl refill nipple, and a non-permanent mounting means. Said bidet assembly is a one-size-fits-all for retrofitting toilets of all sizes and shapes, has no moving parts, valves or controls and which provides fine jet streams of cool water spray—even from chilly cold water source—for cleansing a user's private parts during a toilet bowl refill cycle. Said bidet assembly is mounted inside and behind a toilet tank and inside a bowl and, therefore, is completely hidden from view and keeps water from splashing outside of the bowl. Said bidet assembly can be mounted or removed without tools, in less than two minutes and leaves neither mars nor damage on a toilet.
