  • the overflow 628 has an opening 636, the upper edge 638 of which runs at a distance H below the nozzles 622.
  • the distance H is preferably approximately 20 mm.
  • the channel-shaped or chamber-shaped section 630 of the toilet bowl has a rising trough-shaped bottom 640 starting from the opening 636, which ensures that if inadvertently liquid flows into the section 630, it can flow back into the area 618 of the toilet bowl 610. This results in a kind of self-cleaning. Furthermore, the openings of the recess 630 leading to the side pockets 630, 632 are designed in cross-section such that the channel or the chamber, ie the overflow 628, can be cleaned by hand. The outlets leading to the fastening pockets 632, 634 in the exemplary embodiment extend above the trough-shaped bottom 640.
  • the toilet wall 642 is designed to protrude in comparison to the area 644 running below the opening 636.
  • the geometry and height arrangement of the overflow 628 ensures that if the toilet bowl 610 should be filled with liquid in an inadmissible manner, this is specifically directed from the toilet bowl via the overflow 628 to the fastening pockets 632, 634 to the floor area of the sanitary room in which the Toilet bowl 610 is arranged. This ensures that the nozzles 622, 623 cannot come into contact with the waste water.
  • two nozzles 622, 623 can be provided in order to use this cleaning liquid to clean the inner surface 624 of the toilet bowl 610, i. H. to spray its body 611.
  • the nozzles 622, 623 are arranged diametrically opposite and approximately in the middle of each long side.
  • Each nozzle 622, 623 consists of a mushroom-shaped body (FIG. 27), which is composed of a first section 644 extending along the inner surface 624 in the upper edge 620 of the toilet bowl 610 and a second section 646 extending into the body 611.
  • the second section 646 is penetrated by a central channel 648, through which the rinsing liquid can be fed. From the channel 648 a slot 650 has an arcuate shape and opens into the peripheral edge 652 of the first section 644.
  • the outlet slot 650 extends over an arc which is preferably in the range from 160 ° to 165 ° and faces the bottom region of the bowl 610.
  • the extension takes place symmetrically to the vertical axis 654, which runs perpendicularly or approximately perpendicularly to a plane which is spanned by the nozzles 622, 623 and runs parallel to the upper edge 620 of the toilet bowl 610.
  • the slot 650 merges into a bore 656, 658 at its end, the diameter D of which is larger than the width S of the slot 650.
  • the diameter is approximately 1.8 times the width S of the slot 650.
  • the bores 656, 658 extend from the channel 648, via which the cleaning liquid is fed to the nozzles 622, 623. Since the bores 656, 658 penetrate the exit slot 652 in its respective radial boundary, the bores 656, 658 enclose an angle of approximately 160 to 165 °.
  • the slot 650 spans a plane that is inclined to the outer or inner surface 660, 662 of the first section 644 of the nozzle 622, 623.
  • the bores 656, 658 are preferably formed by drilling, the slot 650 being milled up to the transverse bores 656, 658.
  • the slit 650 is inclined to the surface 60, the former emerges very close to the inner boundary surface 60, which in turn lies flat against the inner surface 624 of the toilet bowl 610 at least in sections.
  • This and the bores 656, 658 result in good flushing behavior, which ensures that the toilet bowl 610 or its inner surface 624 is cleaned to the desired extent, that is also to the required extent at the edge area between the nozzles 622, 623.

Abstract

L'invention concerne un système sanitaire comprenant au moins un dispositif sanitaire servant de point d'origine du liquide à évacuer, tel que des eaux usées, qui afflue sous l'effet de la force de gravité vers un point de collecte relié à une conduite de dépression qui mène à un réservoir collecteur et est reliée à une source de dépression. Une première soupape d'aspiration et une première soupape de ventilation sont associées au point de collecte. Ledit liquide peut également être acheminé jusqu'à la conduite de dépression par ouverture d'une seconde soupape d'aspiration associée au point d'origine.
