Definitions
- the invention relates to a flushing device for a toilet system, with a basin, which has an odor trap on a bottom part and a flushing channel with flushing openings at an upper edge, through which flushing water can be introduced for flushing the basin, the flushing openings in a front area of the Flushing channel have a larger flow than flushing openings arranged on the side.
- Flushing directions of this type are generally known and very widespread. For economic and ecological reasons, there is great interest in reducing the water consumption for washing such sinks by improving the washing effect. The hygienic requirements should also be met with minimal flushing water consumption.
- the water flowing into the basin is directed into a V-shaped recess in the bottom part of the basin.
- This recess is united in a horizontal cross section in a vertical direction towards the bottom of the basin.
- the inventor has set himself the task of creating a flushing device of the type mentioned, which enables reliable and hygienic flushing with an even smaller flushing water quantity.
- the object is achieved according to claim 1 in that the flushing openings are arranged asymmetrically in the front region of the flushing channel and the flushing water in the basin form a flushing vortex. Due to the asymmetrical design of the rinse water inlet, the rinse water in the basin and especially in the lower area of the basin has a swirl and is screwed into the odor trap so to speak. Compared to a symmetrical inlet, for example according to EP 0 407 609 B mentioned above, a more efficient rinsing effect is achieved.
- Solids in particular are very effectively carried away by the rinsing vortex and transported into the odor trap and then into the drain pipe. It has also been shown that the drain nozzle is filled with rinsing water faster than before by means of the rinsing vortex mentioned. This is particularly advantageous in connection with the two patent applications mentioned above and the flushing devices disclosed therein.
- a particularly effective thrust of the rinsing water is achieved according to a further development of the invention in that the said front region of the rinsing water inlet has a plurality of rinsing nozzles which have a much larger passage than further rinsing nozzles arranged on the side.
- the rinsing water flows from the front pool area into the pool with a comparatively narrow but strong rinsing flow isto réelle. At the same time, this winding current receives a twist and, as mentioned, forms a winding vortex.
- an asymmetrical arrangement of the rinse water inlet is achieved by an eccentric arrangement of a further shower head.
- the inflowing rinsing water runs obliquely in the pool to a mirror plane of the pool and preferably completely penetrates this mirror plane.
- FIG. 1 shows a winding bowl in a vertical section and in plan view
- FIG. 2 shows a rear view of a winding device according to the invention
- FIG. 3 shows a partial view of the winding device of FIG. 2.
- the sink 1 shown in FIG. 1 has a circumferential upper edge 3 which forms an approximately egg-shaped opening 22 and which forms in a known manner as a support for a toilet lid, not shown here.
- a circumferential winding channel 2 which forms a widespread space 5 in a rear area.
- the channel 2 is to be connected in the area of the room 5 via an opening 4 with a flushing box, not shown here.
- the sink 1 is attached to a building wall, not shown here, or to a frame.
- the channel 2 has several on an underside 28 of the edge 3 Openings 14, 15 and 16, which form a rinse water inlet.
- the water flowing into the space 5 through the opening 4 is distributed in the channel and passes down through the openings 14, 15 and 16 along the inside 23 and through a somewhat narrowed passage 12 into an odor trap 8 which is in the bottom 7 of the sink 1 is arranged.
- This odor trap 8 also called a siphon, leads to an outlet 9 on the rear side 10.
- an outlet pipe 18 is connected to this outlet 9.
- openings 14 in a front region 13 of the edge 3 are substantially larger than the side openings 15 and openings 16 arranged on the rear.
- the openings 14 have a substantially larger flow cross section than the other openings 15 and 16.
- the flow cross section of FIG Openings 14 are each several times larger than that of openings 15 and 16. The vast majority of the rinse water thus flows through openings 14.
- the openings 14 are formed by a central main opening 14a and laterally arranged openings 14b, 14c and 14d.
- the openings 14b and 14c are arranged symmetrically to the main opening 14a and each have the same flow cross-section.
- the somewhat smaller opening 14d is only present once and is somewhat smaller than the openings 14c.
- the openings 14 are thus asymmetrical in such a way that a flow component is generated through the opening 14d in the direction of the arrow 24, which gives the inflowing rinsing water 17 a direction which runs obliquely with respect to a mirror plane S.
- the rinsing water 17 thus does not flow centrally and symmetrically through the mirror plane S into the passage 12, but with a swirl runs clockwise in Figure 1.
- the rinsing water 17 is approximately funnel-shaped in an upper area 17a, essentially laminar in a central area 17b and helical in a lower area 17c.
- the openings 14 form downwardly directed nozzles, as can be seen in FIG. 1.
- the flow directions are indicated in FIG. 1 with dash-dotted lines.
- the point P shows the point on which the openings 14a, 14b and 14c or the corresponding nozzles are focused.
- the point P is located on the inside 23b of the basin and in the mirror plane S.
- the opening 14d is not focused on the point P, but is directed at a point P ′ which is slightly above the point P. As mentioned, this causes a swirl to be exerted on the flow of the flushing water 17.
- the rinsing water 17 flows helically into the odor trap 8 and from there into the drain pipe 18 shown in FIGS. 2 and 3.
- the constriction 18a causes the drain pipe 18 to be filled with rinsing water and a closed flow is formed.
- a suction effect is generated in the drain pipe 18 and the rinsing water 17 passes through a bend 18b to a nozzle 18c and finally into a disposal line 21 which is sealed by a rubber seal 20 on the nozzle 18c.
- the above-mentioned suction effect leads to a very rapid emptying of the sink 11.
- the rinsing water is accelerated by the suction effect and thus solids are entrained and washed away.
- the above-mentioned asymmetrical introduction of the rinsing water thus increases the effect of the drain pipe 18 and in particular the suction effect due to the special design of the drain pipe 18.
