<p>Plumbing facility consisting of a toilet bowl extended at its base by a discharge pipe and having a siphon placed therebetween. The toilet bowl (1) is supplied with rinsing water and, at its upper edge, the wall is bent inwards to form a flange (3), open at the base, for guiding and distributing rinsing water from the outlet (2). The invention is characterized in that the pipe for supplying rinsing water is arranged tangentially to the substantially circular or ovoid circuit of the flange (3), to produce a laminar flow current, along a helicoidal and spiral path at the base of the bowl which gently slopes (5) from the periphery (4) to a substantially central cylindrical well (6) for discharge to the lower siphon (9a).</p> |
