Description

Technical Field

[0001] The invention relates to a flushing water distributor according to the preamble of claim 1 . Background Art

[0002] In sanitary ware, in particular ceramic sanitary ware, a flushing water distributor is installed in the sanitary ware for better distribution of the flushing water. Such a flushing water distributor is disclosed, for example, in DE 33 15 926. Three flushing water flows are provided, of which two flushing water flows each flow laterally into the toilet bowl and one flushing water flow flows straight into the toilet bowl.

[0003] EP 3 453 805 likewise discloses a flushing water distributor.

[0004] Toilet bowls are increasingly being designed without a flushing rim. This results in an optimal introduction of the flushing water into the bowl. Flush water distributors known from the prior art have the disadvantage that the flushing water is not optimally introduced into the bowl. This can cause the flushing water to overflow from the bowl or to splash out of the bowl. This effect has a particularly negative effect in the aforementioned rimless toilets. Summary of the invention

[0005] Based on the prior art, the invention is based on the object of providing a flushing water distributor which overcomes the disadvantages of the prior art. A particularly preferred object is to provide a flushing water distributor which can be installed so that the flushing water is optimally guided into the toilet.

[0006] The object is achieved by a flushing water distributor according to claim 1. Therefore, a flushing water distributor for sanitary ware comprises: a pipe element having a flushing water channel extending along a central axis, the flushing water channel extending from an inlet opening to at least one outlet opening, wherein flushing water can be guided from the inlet opening to the at least one outlet opening in the flow direction and can be output from the at least one outlet opening to the sanitary ware. The pipe element has a supporting section with a supporting surface on the outside, via which the flushing water distributor can be supported directly or indirectly in a supporting part of a receiving part of the sanitary ware. In this case, the flushing water distributor can be inserted into the supporting part of the sanitary ware and is in contact with the supporting part by means of the supporting surface and is thus supported in the receiving part. In this case, the supporting surface is configured so that the flushing water distributor can be inserted into the supporting part in a manner oriented around the central axis with respect to the rotational position.

[0007] Such a configuration of the support surface provides the advantage that incorrect insertion of the flushing water distributor into the receptacle can be prevented. This allows the at least one outlet opening to be optimally oriented with respect to the interior of the sanitary ware. This allows the flushing water to be optimally guided into the interior of the sanitary ware to be flushed.

[0008] Furthermore, the advantage results that the flushing water distributor is prevented from rotating during use, for example due to the action of forces during a cleaning process.

[0009] The flushing water distributor is oriented with respect to its rotational position about the central axis in such a way that the at least one outlet opening is oriented into the interior of the sanitary ware.

[0010] In one embodiment, at least two or exactly two outlet openings are arranged. The flushing water distributor is accommodated in the receptacle in such a way that, when viewed in the installed position, the two outlet openings are located at the same height and thus can discharge symmetrical water flows into the interior of the sanitary ware, viewed in the flow direction. Preferably, the water flow is such that the surface of the sanitary ware is substantially completely wetted.

[0011] In another embodiment, at least three or exactly three outlet openings are arranged. The flushing water distributor is accommodated in the receptacle in such a way that, viewed in the installed position, the two lateral outlet openings are located at the same height and can therefore discharge a symmetrical water flow into the interior of the sanitary ware, viewed in the flow direction. Preferably, the water flow is such that the surface of the sanitary ware is substantially completely wetted. The third outlet opening is located between the two lateral outlet openings and provides a jet in the direction of the siphon, so that the siphon can be flushed.

[0012] Preferably, the contact surface is designed as a contact surface around a central axis.

[0013] With regard to the two lateral discharge openings in both embodiments, one of the discharge openings is located to the right of the central axis and the other of the discharge openings is located to the left of the central axis. Particularly preferably, the two discharge openings are arranged opposite to each other with respect to the central axis so that the flushing water can be discharged to the two sides arranged opposite to each other with respect to the central axis.

[0014] The sanitary ware is preferably a toilet or a urinal. The sanitary ware comprises an inner space and a siphon respectively. In addition, as described below, the sanitary ware has a receiving portion with a support portion, and the flushing water distributor can be loaded into the receiving portion.

[0015] Preferably, the contact surface has a greater extent in the direction of a first axis extending perpendicularly through the central axis than in the direction of a second axis extending perpendicularly to the central axis and perpendicularly to the first axis.

[0016] This results in the advantage that the orientation can be achieved by a simple shaping of the support surface. Therefore, no additional elements need to be provided.

[0017] The first axis extends in the vertical direction when viewed in the installed position, and the second axis extends in the horizontal direction when viewed in the installed position. The opposite arrangement is also possible.

[0018] Preferably, the extension in the direction of the first axis is at least 10% greater than the extension in the direction of the second axis.

[0019] The support surface is particularly preferably designed as non-circular or non-circular when viewed in a cross section transverse to the central axis. The support surface is particularly preferably designed as oval or elliptical when viewed in a cross section transverse to the central axis. However, the support surface of the shape can also have a flat surface area.

[0020] In a particularly preferred variant, the contact surface has two planar surface areas which are spaced apart from one another and which are each connected at the end sides via two semicircular surface areas.

[0021] Preferably, in order to directly support the flushing water distributor in the receiving portion, the supporting surface is exposed to the outside. That is to say, the supporting surface is not covered by other elements, and the supporting surface can directly form contact with the receiving portion.

[0022] In order to indirectly support the flushing water distributor, a seal, in particular a seal having a plurality of sealing lips around the center axis, is arranged between the support surface and the receiving portion. Thus, the flushing water distributor is indirectly supported in the receiving portion via the seal. The seal here extends completely around the center axis.

[0023] Preferably, the seal is arranged on the support surface before the flushing water distributor is assembled. The seal can be constructed as a component independent of the flushing water distributor. Alternatively, the seal can also be integrally molded on the support surface.

[0024] Observed in a cross section transverse to the central axis, the pipe element or the flushing water channel is preferably configured to be circular. Thus, a pipe of a flushing line with a suitable diameter can be easily connected to the flushing water distributor.

[0025] Preferably, the pipe element or the flushing water channel is designed to be circular at the inlet opening, so that the flushing pipe can extend into the pipe element via the inlet opening. A seal is preferably arranged between the outside of the flushing pipe and the inside of the pipe element.

[0026] A flushing water channel extending between an inlet opening and at least one outlet opening is delimited on the outside by a side wall, wherein the support surface is at least partially spaced apart from the side wall; and / or wherein the support surface is at least partially part of the side wall.

[0027] Particularly preferably, a portion of the support surface is spaced apart from the side wall and a portion of the support surface is provided by the side wall.

[0028] The arrangement of the contact surface at a distance from the side wall results in the advantage that the inner cross section of the pipe element or of the flushing water channel can be designed independently of the shape of the side wall.

[0029] Viewed in the flow direction, a guide wall is preferably arranged in the flushing water channel before the outlet opening, which divides the flushing water channel into at least one right-hand distribution section and at least one left-hand distribution section, wherein the right-hand distribution section leads to one of the outlet openings and the left-hand distribution section leads to the other of the outlet openings.

[0030] Preferably, at least one guide wall further divides the flushing water channel into an intermediate distribution section, which is located between the two distribution sections and leads to a further discharge opening.

[0031] Preferably, the further outlet opening is oriented downward in the installed position and serves for flushing the siphon.

[0032] Preferably, the cross section of the flushing water channel or of the tube element is essentially circular before the distribution section.

[0033] Preferably, the flushing water distributor further comprises a fastening element, by means of which the flushing water distributor can be fixed relative to the sanitary ware.

[0034] Preferably, the fastening element has two support arms which protrude from the tubular element substantially transversely to the center axis and engage on a support on the sanitary item.

[0035] The sanitary device comprises a flushing water distributor according to the above description and a flushing pipe, wherein the flushing pipe projects via an inlet opening into the pipe element or the flushing water channel, and wherein a seal is arranged between the pipe element and the flushing pipe.

[0036] A sanitary ware, in particular a toilet or a urinal, comprises: a receptacle for the flushing water distributor described above or a receptacle for a flushing water distributor according to the flushing water distributor device described above, wherein the receptacle has a support portion for supporting the flushing water distributor via a support surface of the flushing water distributor, wherein the support portion is constructed to be complementary or matching relative to the support surface.

[0037] The term “complementary” is to be understood as meaning that the support part and the support surface are designed in a matching manner, so that the flushing water distributor can be supported directly or indirectly in the support part or the receptacle.

[0038] Preferably, the receptacle also has a guide region which is arranged in front of the support portion, as viewed in the insertion direction of the flushing water distributor, wherein the guide region is designed to be at least partially open on the circumferential side.

[0039] Preferably, the flushing water distributor and the flushing pipe consist of plastic.

[0040] Further embodiments are given in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] exist Figure 1 2 shows a sanitary ware 2 with a flushing water distributor 1. The flushing water distributor 1 can be installed in the sanitary ware 2 and distributes flushing water in an interior 26 of the sanitary ware 2. In this case, flushing water flows from the flushing water distributor 1 into the interior 26 and into the siphon area 27 of the sanitary ware 2. The flushing water distributor 1 is supplied with flushing water via a flushing pipe 22.

[0053] exist Figure 2 , a perspective view of a flushing water distributor 1 is shown. The flushing water distributor 1 comprises a tube element 3 extending along a central axis M. The tube element 3 has a flushing water channel S extending from an inlet opening 4 to at least one outlet opening 5, 6, 7. Thus, flushing water can be guided from the inlet opening 4 to at least one outlet opening 5, 6, 7 in a flow direction F. The flushing water can then be discharged into the sanitary ware 2 via the at least one outlet opening 5, 6, 7. In the embodiment shown, three outlet openings 5, 6, 7 are arranged. The middle outlet opening 7 is located between the two lateral outlet openings 5, 6. The middle outlet opening 7 is oriented here into the siphon region 27, and the two lateral outlet openings 5, 6 are oriented to the wall of the interior space 26.

[0054] The pipe element 3 has a support section 8 on the outside. The support section 8 comprises a support surface 9, via which the flushing water distributor 1 can be supported directly or indirectly in a support 24 of a receptacle of the sanitary ware 2. The receptacle 10 is accessible from the rear wall 28 of the sanitary ware 2. The flushing water distributor 1 can thus be inserted into the receptacle 10 from the rear wall 28.

[0055] exist Figure 3 and 4 The insertion of the flushing water distributor is shown in more detail in FIG. Figure 3 The sanitary ware 2 is shown from below. The receptacle 10 here extends from the rear wall 28 into the interior 26. The receptacle 10 here has a support 24 for supporting the flushing water distributor 1. The receptacle 10 here also comprises a guide region 25 which is arranged in front of the support 24, as viewed in the insertion direction of the flushing water distributor 1, wherein the guide region 25 is designed to be partially open on the circumferential side.

[0056] Figure 4 The flushing water distributor 1 is shown integrated into a sanitary fixture 2 .

[0057] exist Figure 5 2 shows a rear side view of a sanitary ware 2 in which a flushing water distributor 1 is installed. Here, the support portion 24 of the receiving portion 10 has a shape complementary to the support surface 9. That is, the support surface 9 is configured to match the support portion 24.

[0058] exist Figure 6 1 shows an exploded view of the flushing water distributor 1. The flushing water distributor 1 comprises a support surface 9 on the outside, such as Figure 5The bearing surface shown is designed so that the flushing water distributor 1 can be inserted into the bearing 24 oriented about the central axis M with respect to the rotational position. In the embodiment shown, the first seal 13 with the circumferential sealing lip 14 is arranged on the bearing surface 9. This means that the flushing water distributor 1 is indirectly supported in the bearing 24 of the receptacle 10. In the embodiment shown, the bearing surface 9 has a greater extent in the direction of the first axis A1 extending perpendicularly through the central axis M than in the direction of the second axis extending perpendicularly to the central axis M and perpendicularly to the first axis A1. This means that it has a smaller extent in the direction of the second axis A2.

[0059] In a particularly preferred embodiment according to the figures, the support surface 9 has two planar surface areas 11 spaced apart from one another. The planar surface areas 11 extend at right angles to the second axis A2 and parallel to the first axis A1 and parallel to the center axis. The surface areas 11 are each connected at the end via two semicircular surface areas 12. The support 24 is designed in the same way. The support 24 also has planar areas, which are connected via two semicircular surface areas 12.

[0060] In other embodiments, the contact surface 9 can also be designed to be oval or elliptical when viewed in a cross section transversely to the central axis M. A non-circular design is advantageous in this case.

[0061] In the embodiment shown, the support surface 9 extends completely around the central axis and does not directly accommodate parts of the side walls 18 which delimit the flushing water channel S on the outside. This means that the support surface 9 is at least partially spaced apart from the side walls 18 .

[0062] Viewed in a cross section transversely to the center axis M, the tubular element 3 has a circular cross section at the inlet opening 4. A circular cross section is advantageous because the flushing pipe 22 with the corresponding second seal 23 can be inserted into the tubular element 3 or the flushing water channel S via the inlet opening 4. The cross section of the tubular element 3 or the flushing water channel S is independent of the cross section of the support surface 9.

In the flushing water channel S, viewed in the flow direction F, at least one guide wall 29 is arranged before the outlet openings 5, 6, 7. In the embodiment shown, different guide walls 29 are arranged. The guide wall 29 is part of an insert 30 here. The insert 30 is formed separately from the pipe element 3 and can be partially inserted into the flushing water channel S. Therefore, the insert 30 also partially extends into the flushing water channel S and is fixed accordingly relative to the pipe element 3. At least one guide wall 29 divides the pipe element 3 into a right distribution section 15 and a left distribution section 16. In addition, the pipe element 3 is divided into a middle distribution section 17, which is located between the two distribution sections 15, 16 mentioned and leads to the other outlet opening 7.

[0064] Furthermore, the flushing water distributor 1 comprises a fastening element 19 which is fastened to the flushing water distributor 1 at the Figure 1 The fastening element 19 serves to fix the flushing water distributor 1 relative to the sanitary fixture 2. The fastening element 19 has two support arms 20 which protrude from the tube element 3 substantially transversely to the center axis M. The support arms 20 rest on a support 24 on the sanitary fixture 2 or engage in a support 24.
