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.

1 . A bidet assembly whose water supply tube is connected to the toilet bowl refill nipple as its source of water and wherein said water supply tube has an anti-siphoning means—located above the toilet tank water line—that introduces air into the water supply tube after the source of water is shut off by a valve actuated by the float. 
   
   
       2 . The bidet assembly of  claim 1  wherein said anti-siphoning means is selected from the list of
 check valve and   pinhole   
   
   
       3 . A bidet assembly whose water jet nozzle is 90° elbow flexible-tube fitting, wherein its nozzle's outside diameter is the same as the inside diameter of the bidet assembly's instant-connect tube fitting. 
   
   
       4 . The bidet assembly of  claim 3  wherein said 90° elbow flexible-tube fitting has at least one barb, whose maximum outside diameter is not more than 0.025 inch larger than the nozzle's outside diameter. 
   
   
       5 . A bidet assembly whose non-permanent mounting means is a long and stiff member that has a pre-form shape made from bending around a bending-mold whose shape is the rear half of the corner elliptical contour, which is below the toilet bowl rim lip. 
   
   
       6 . The bidet assembly of  claim 5  wherein the center section of said bending-mold has a straight section length of less than 6 inches.
