Definitions

• the invention relates to a water-saving toilet system, with an odor trap having a basin and a flushing device with which the basin can be flushed and with a drain, which is arranged in the flow direction after the odor trap and is to be connected to a disposal line and through which flushing water is also transported during flushing Parts of the disposal line can be supplied.
• a water-saving flushing device for a toilet is proposed by DE 298 07 813 Ul.
• a nozzle in the bottom of the odor trap through which part of the winding water is injected diagonally into the outlet during a winding process.
• the nozzle is located at a front end of a discharge slope, so that a negative pressure is generated in the drain when a bent discharge pipe is full. A downward pulling force of the watercourse is to be increased by the nozzle.
• Vacuum toilets have the disadvantage that a vacuum source has to be installed, which is comparatively complex and takes up additional space. In addition, noises during vacuum actuation can hardly be avoided. In the case of toilet facilities with a nozzle in the odor trap, corresponding lines to this nozzle are required. This nozzle significantly increases the cost of manufacturing the toilet bowl. In addition, the nozzle can become clogged, which leads to malfunctions.
• the invention has for its object to provide a water-saving toilet system which avoids the disadvantages mentioned above and which is nevertheless effective and reliable and inexpensive to manufacture.
• the drain has an essentially vertical area which has a smaller free cross section than a further area of the drain arranged above this area, such that in the case of a flushing m the vertical Area more water flows in than away from it and a closed water flow forms which essentially sucks the odor trap.
• the essential features of the invention relate to the process. According to a further development, this can essentially be formed by a flow sheet which len area with the comparatively small free cross section and which can be attached to any common toilet bowl. A major advantage of the invention is thus seen in the fact that such a drainage sheet is attached to existing toilet bowls and thus a reduction in water consumption is possible very cost-effectively.
• the drain elbow can be made of plastic as a molding and enables very different installation situations. In particular, a floor drain or a wall connection is possible. For the floor drain, the drain pipe runs through the building floor and for the wall connection through the building wall.
• the drain has a deflection bend below said vertical area, which has a free cross-section that is larger than the free cross-section of said vertical area.
• the invention also relates to a drain elbow for a water-saving toilet system.
• This is preferably a fitting that runs horizontally at the upper end for connection to a nozzle of a toilet bowl. At this end the drain elbow can be attached to the nozzle of the bowl.
• a horizontally running region is preferably also provided at the lower end of the drain bend. In the horizontal area there is a deflection bend, which forms a so-called swamp after winding. The free cross section of the deflection bend is larger than the free cross section of the vertical area. In the lower horizontal area, the drain elbow is connected to the disposal line. As mentioned, this can run vertically through the building floor or horizontally through a building wall. Further advantageous features result from the dependent claims, the following description and the drawings.

• the end 15 leads over a bend 16 m to a vertical region 17 which has a free cross section C and, as can be seen, is arranged behind the support frame 6.
• the vertical region 17 is substantially longer than it is wide and leads at the lower end to a deflection curve 18 which is connected to a horizontal outlet end 19 after a rising region 18a.

• the free cross-section E of the outlet end 19 is also smaller than the cross-section D of the deflection bend 18.
• the free cross-section D is again larger than the cross-section C.
• the ratio of the cross section C to the cross section A is preferably less than 0.7.
• the free cross section D is larger than the free cross section C. It is preferably larger by the amount which is formed by the height d of the backwater 22 (FIG. 2b).

• the inside diameter according to the cross section B is, for example, 100 mm.
• the diameter in the area of the cross section A is, for example, about 70 to 80 mm. Seen in the direction of flow, the free cross section after the connection piece 12 is thus considerably narrower. In the area of the deflection curve 18 there is then an expansion and then a further narrowing.

• a closed flow 27 ′ is formed comparatively quickly in the discharge arch 14, as shown in FIG. 5.
• the level 24 now rises approximately to the top 30 of the deflection curve 37, as FIG. 5 clearly shows.
• the winding action can be further increased if, according to FIG. 9, the run-off nozzles 9a run obliquely with respect to the bowl rim 8a.
• a swirl vortex 32 shown in FIG. 9 is formed, which extends from the edge 8a to the drain opening 31 and which causes the bowl 8 to be filled up more quickly and to a greater degree of rinsing and thus more intensive cleaning of the bowl 8.
• the vortex 32 thus supports the effect of the flow sheet 14 explained above.
• FIGS. 10 to 12 show a drain bend 14 'which has an upper and essentially horizontal end 15', a region 17 ', a deflection bend 18' and a drain end 19 '.
• This drain bend 14 ' is preferably provided for a floor connection close to the wall and perpendicular, as shown in FIG. 10.
• This drain arch 14 ' requires little space between a building wall 35 and Rear side 36 of a toilet bowl 8. It is essential in this drain bend 14 'that the deflection bend 18', which is essential for a back pressure, lies with the vertical region 17 'in a plane which is essentially perpendicular to the longitudinal axis of the connecting piece 12.
• the drain end 19 ' which here extends vertically downward, preferably also runs in this plane.
• the region 17 which runs vertically in the discharge arch 14 is an obliquely extending region 17 'in this variant.
• the diameter C of this area 17 ' is also substantially smaller than the diameter B' of the connecting bend 16 '. Since the drain arch 14 'takes up little space in depth, the toilet bowl 8 can be mounted particularly close to the building wall 35, which is a significant advantage, particularly in small rooms. It is also advantageous that the drain bend 14 'can be produced in one piece and an intermediate piece 20 is not required.
• the drain arch 14 'thus enables particularly simple assembly.
• the discharge arch 14 ′′ shown in FIGS. 13 to 16 is preferably also a blow molded part made of plastic and is fastened to the rear wall 8a of the bowl 8 at an upper edge 41. At a lower, vertically running end 19 ′′, the drain bend 14 ′′ is connected to the disposal line 21 by means of a rubber seal 40.

• the deflection bend 43 forms a receiving space 45 for the water flowing through the nozzle 12 into the outlet bend 14 ′′.
• Below the deflection bend 43 there is a constriction 44 which reduces the free inner cross section B "to the smaller inner cross section C".
• the outlet arch 14 ′′ is bent in an S shape in a plane running parallel to the rear side 8a.

Another rib 52 is arranged directly at the upper end of the outlet end 19 ′′. The exact course of the S-shaped area and the arrangement of the ribs 46 to 52 can be seen in FIGS. 13 to 15. The functioning of the flow sheet 14 ′′ is explained below.

• This constriction forms a closed flow through which the rinsing water is effectively sucked off into line 21.
• the ribs 46 to 52 form further constrictions, which support and reinforce the formation of the closed flow and thus the suction effect. As explained above, it should be possible to rinse as little rinse water as possible. However, a minimum amount of rinsing water is required to form a closed flow.
• the ribs 46 to 52 make it possible to further reduce this required amount.
• ribs 46 to 52 could essentially be seen in that they break the flow of the rinsing water and thus support the formation of a closed flow. It is also advantageous that such ribs 46 to 52 are comparatively simple in the blow molding process. are adjustable. Since, as explained, the curves of the drain bend 14 ′′ run in a plane parallel to the rear 8a, the space requirement is comparatively small. Finally, the assembly of the drain elbow 14 '' is very simple.
