Definitions
- the invention is relative to a flushing device for a toilet system with a bowl comprising an odor trap on a bottom part and comprising a flushing conduit with flushing openings on an upper edge through which openings flushing water can be introduced for flushing the bowl.
- the flushing openings have a greater flowthrough in a frontal area of the flushing conduit than laterally arranged flushing openings do.
- Flushing devices of this type are generally known and very widespread. For reasons of economy and ecology there is great interest in being able to reduce the consumption of water for the flushing of such flush bowls by improving the action of flushing. Hygienic requirements should be able to be met even in the case of minimal consumption of flushing water.
- the invention has the problem of creating a flushing device of the cited type which makes possible a reliable and hygienic flushing with a lesser amount of flushing water.
- the problem is solved in accordance with claim 1 in that the flushing openings are asymmetrically arranged in said frontal area of the flushing conduit and that the flushing water forms a flushing vortex in the bowl.
- the flushing water receives a spin [twist] in the bowl and especially in the lower area of the bowl and screws itself, so to say, into the odor trap.
- a more efficient flushing action is achieved in comparison to a symmetric inlet, e.g., according to EP 0,407,609 B cited above.
- solid matter is carried along very effectively by the flushing vortex, transported into the odor trap and subsequently into the runoff pipe.

Abstract
Description
- The invention is relative to a flushing device for a toilet system with a bowl comprising an odor trap on a bottom part and comprising a flushing conduit with flushing openings on an upper edge through which openings flushing water can be introduced for flushing the bowl. The flushing openings have a greater flowthrough in a frontal area of the flushing conduit than laterally arranged flushing openings do.
- Flushing devices of this type are generally known and very widespread. For reasons of economy and ecology there is great interest in being able to reduce the consumption of water for the flushing of such flush bowls by improving the action of flushing. Hygienic requirements should be able to be met even in the case of minimal consumption of flushing water.
- In the flushing device according to EP 0,407,609 B the water flowing into the bowl is conducted into a V-shaped recess in the bottom part of the bowl. This recess is constricted [narrowed] in horizontal section in a vertical direction towards the bottom of the bowl.
- The two Swiss patent applications 99/0827 and 99/1378 of the applicant teach flushing devices in which an improved suction action can be achieved by means of a runoff [discharge] pipe. These runoff pipes are constricted in a vertical area. This constriction achieves a suction action which brings about an improved flushing of the flush bowl. These two patent applications are cited as part of the disclosure.
- The invention has the problem of creating a flushing device of the cited type which makes possible a reliable and hygienic flushing with a lesser amount of flushing water. The problem is solved in accordance with
claim 1 in that the flushing openings are asymmetrically arranged in said frontal area of the flushing conduit and that the flushing water forms a flushing vortex in the bowl. As a result of the asymmetric formation of the inlet of the flushing water the flushing water receives a spin [twist] in the bowl and especially in the lower area of the bowl and screws itself, so to say, into the odor trap. A more efficient flushing action is achieved in comparison to a symmetric inlet, e.g., according to EP 0,407,609 B cited above. In particular, solid matter is carried along very effectively by the flushing vortex, transported into the odor trap and subsequently into the runoff pipe. It also turned out that as a result of said flushing vortex the runoff pipe is filled more rapidly with flushing water than previously. This is especially advantageous in the context of the two patent applications cited above and of the flushing devices disclosed in them. - An especially effective thrusting force of the flushing water is achieved in accordance with a further development of the invention in that said frontal area of the flushing water inlet comprises several flushing jets with a significantly larger throughput than other, laterally arranged flushing jets. The flushing water flows with a comparatively narrow but strong flushing current from said frontal bowl area into the runoff opening. At the same time, this flushing current receives a spin and forms, as mentioned, a flushing vortex. An asymmetric arrangement of the flushing water inlet is achieved in accordance with a further development of the invention by an eccentric arrangement of another flushing jet. The incoming flushing water runs obliquely in the bowl to a mirror plane of the bowl and preferably penetrates this mirror plane completely.
- Further advantageous features result from the dependent claims, the following description and the drawings.
- An exemplary embodiment of the invention is explained in detail in the following with reference made to the drawings.
- FIG. 1 shows a flush bowl in vertical section and in a top view.
- FIG. 2 shows a view of the back side of the flushing device in accordance with the invention.
- FIG. 3 shows a partial view of the flushing device of FIG. 2.
-
Flushing device 1 shown in FIG. 1 comprises circumferentialupper edge 3 that forms an approximately egg-shaped opening 22 and functions in a known manner as a support for a toilet cover (not shown here). Circumferential flushingconduit 2 is arranged inedge 3 and forms widened-outspace 5 in a rear area.Conduit 2 is to be connected in the area ofspace 5 via opening 4 to a toilet flush tank (not shown here).Flush bowl 1 is fastened onback side 10 to a building wall or a frame (not shown here). -
Conduit 2 comprisesseveral openings bottom 28 ofedge 3 which openings form a flushing water inlet. The water flowing intospace 5 throughopening 4 is distributed in the conduit and passes through saidopenings inner side 23 and through a somewhatconstricted passage 12 intoodor trap 8 arranged inbottom 7 offlush bowl 1. Thisodor trap 8, also called a siphon, leads toexit 9 onback side 10.Discharge pipe 18 is connected to thisexit 9 in accordance with FIGS. 2, 3. - As FIG. 1 in particular clearly shows, openings14 in
frontal area 13 ofedge 3 are significantly larger thanlateral openings 15 andopenings 16 arranged on the back side. Openings 14 have a significantly larger flowthrough section than theother openings openings - As is apparent,
openings 14 a are formed by central main opening 14 as well as laterally arrangedopenings Openings smaller opening 14 d is present only once, as is apparent, and is somewhat smaller thanopenings 14 c. Thus, on the whole openings 14 are asymmetrically designed in such a manner that a flow component is produced through opening 14 d in the direction ofarrow 24 which imparts a direction to incoming flushingwater 17 which direction runs obliquely relative to mirror plane S. Thus, flushingwater 17 does not flow centrally and symmetrically through mirror plane S intopassage 12 but rather with a spin which runs clockwise in FIG. 1. According to FIG. 1 flushingwater 17 is approximately funnel-shaped inupper area 17 a, essentially laminar inmiddle area 17 b and helical inlower area 17 c. - Openings14 form downwardly directed jets, as can be seen in FIG. 1. The directions of flow are indicated in FIG. 1 with dotted lines. Point P shows the point onto which openings 14 a, 14 b and 14 c and the corresponding jets are focused. Point P is located on inside 23 b of the bowl and in mirror
plane S. Opening 14 d is not focused on point P but rather is directed onto point P′ located slightly above point P. This imparts a spin, as mentioned, to the flow of flushingwater 17. - Flushing
water 17 flows as mentioned above helically intoodor trap 8 and from the latter intorunoff pipe 18 shown in FIGS. 2 and 3.Constriction 18 a brings it about thatrunoff pipe 18 is filled with flushing water and a closed flow is formed. As a result, a suction action is produced inrunoff pipe 18 and flushingwater 17 passes via bend [elbow] 18 b to connectingpiece 18 c and finally into removal line 21 which is sealed onto connectingpiece 18 c byrubber seal 20. This suction action results in a very rapid emptying offlush bowl 11. The flushing water is accelerated by the suction action, which causes solid matter to be entrained and flushed away. Thus, the asymmetric introduction of the flushing water mentioned above reinforces the action ofrunoff pipe 18 and in particular the suction action by virtue of the particular shape ofrunoff pipe 18.
