Definitions

  • the invention relates to a toilet bowl comprising a front area serving as a urine part with a first opening leading to a first drain and possibly closable and a second area serving as a faecal part leading to a second drain for separate drainage of urine and feces, the front Area has a shallower depth than the rear area.
  • toilet bowls or basins into two areas by a partition and thus to separate them spatially, a rear area being intended for faeces and a front area for urine, so that separate routing is made possible
  • Corresponding separate toilets are e.g. B. from FR 2,674, 881 AI or WO 92/190824 known.
  • a disadvantage of corresponding separating toilets is the partition, which not only requires frequent cleaning, but also causes problems in terms of production technology. Since the dividing wall between the front and rear parts runs up in the direction of the toilet bowl opening, the distance between the partition wall and a person using the toilet bowl becomes relatively small, so that there is also a need to get used to it. Due to the raised partition, the area of the toilet bowl that delimits the front area, that is to say the urine part, is relatively large, so that considerable amounts of cleaning fluid are required, which are discharged via the front outlet from the urine part. To avoid this, it is possible to provide the partition with an opening (FR 2,674,881 AI). As a result, however, there is a further outlay in mold construction for corresponding toilet bowls.
  • the present invention is based on the problem of developing a toilet bowl of the type mentioned at the outset in such a way that a structurally simple measure enables a safe separation between urine and faeces, so that they can be easily removed separately from one another. Furthermore, the consumption of water for cleaning the front area, that is to say the urine part, should be able to be reduced, wherein the water can optionally be used for simultaneous cleaning of the rear area, that is to say the fecal part.
  • the first area is delimited by a curved wall surface that extends inclined in the direction of the second area of the toilet bowl and extends from the edge of the toilet bowl to the floor area, that the floor area merges into the second section without a partition and that the urine-draining first opening is located in the bottom surface and runs in particular in a flat or substantially flat region of the bottom surface.
  • the opening itself runs in the saddle-shaped bottom area of the urine part, ensuring that when the opening is closed, liquid cannot collect in the bottom area. Rather, it flows completely into the fecal part. In other words, the closure of the opening should run flush with the floor surface or merge into it.
  • a development of the invention provides that the bottom surface has liquid in the direction of the first opening has conductive structuring such as rib-like or web-like elevations, which may continue in the wall surface.
  • the rib-like or web-like elevations radiate from the first opening, preferably at a distance from it.
  • five radiating ribs or webs can be formed, two of which extend along the transition to the rear area of the toilet bowl, a web or a rib along the longitudinal sectional plane of the toilet bowl towards the front edge and two further ribs or webs between the aforementioned extend.

  • the closure element with a circumferential edge can rest on the insert or lie directly sealingly on the edge of the first opening of the toilet bowl, which runs within the first area, ie the urine part.
  • the closure part which has a mushroom-shaped geometry, runs coaxially within the first opening, with either the insert or a sealing element extending between the closure element and the edge of the opening, in order to ensure a sufficient seal between the closure element and the toilet bowl when the opening is closed. As a result, liquid cannot flow through the first opening in the corresponding drain when cleaning the front area.
  • the closure element can have radially extending openings such as bores, which merge into a central recess, such as a blind hole, which merges into the first outlet. If the closure element is raised, liquid such as urine can flow to the first outlet via the radial bore and the blind hole.

Abstract

L'invention concerne une cuvette de W-C (10) comportant une zone avant (12) pour évacuer l'urine, qui présente une première ouverture (26) menant vers une première évacuation et pouvant éventuellement être fermée, ainsi qu'une seconde zone arrière recueillant les matières fécales et menant vers une seconde évacuation (16). Afin d'assurer d'une part une séparation fiable de l'urine et des matières fécales et d'autre part de permettre un nettoyage aisé de la partie qui recueille l'urine, il est prévu que la zone avant (12) présente une surface de base (20) s'étendant de manière inclinée en direction de la seconde zone (14) et se transformant sans paroi de séparation, en zone arrière (14). La première ouverture (26) qui évacue l'urine se trouve dans la surface de base.
