Description

TECHNICAL AREA

The present invention relates to a flush water distributor for a sanitary article according to the preamble of claim 1.

STATE OF THE ART

In, in particular ceramic, sanitary ware, rinse water distributors are used for better distribution of rinse water in the sanitary ware. For example, DE 33 15 926 discloses such a flushing water distributor. Three flushing water streams are provided, two of the flushing water streams flowing laterally into the toilet bowl and one of the flushing water flowing straight into the toilet bowl.

However, DE 33 15 926 has the disadvantage that the mean flushing water flow is unfavorable. Especially with regard to the flushing performance of a siphon.

DISCLOSURE OF THE INVENTION

Based on this prior art, the invention is based on an object of specifying a flushing water distributor which overcomes the disadvantages of the prior art. In particular, a flushing water distributor is to be specified which has a good flushing performance of the siphon and preferably provides good surface flushing of the ceramic.

This object is achieved by the subject matter of claim 1. Accordingly, a flushing water distributor for a sanitary article, in particular a toilet bowl or a urinal, an outer wall extending around a central axis with an inner wall directed towards a flushing water channel, a separating part at least partially located in the flushing water channel, which divides the flushing water channel into at least a right distribution section, a left distribution section and a middle distribution section. The flushing water channel has an inlet opening through which flushing water can be fed into the flushing water channel. Each of the distribution sections has an outlet opening through which rinsing water can be discharged from the sanitary article. Rinsing water can be guided in the direction of flow from the inlet opening to the distribution sections and their outlet openings. The middle distribution section has a guide surface with a front edge and a rear edge, which guide surface is arranged in the middle distribution section in such a way that the flow in the middle distribution section experiences a throttling effect or can be throttled in the area of the guide surface.

The throttling of the flushing water flow in the central distribution section has the advantage that an improved flushing of the siphon area can be achieved. The jet of rinsing water from the middle distribution section enters the siphon area in a throttled manner. The throttling is particularly advantageous for flushing out light and soft materials such as toilet paper.

[0007] Furthermore, the guide surface has the advantage that the water in the region of the throttling is guided over a certain guide path, namely over the length of the guide surface as viewed in the direction of flow. As a result, the flow in the throttle element can be guided or calmed without major turbulence. The guidance is also advantageous with a view to the deflection surface described below.

As mentioned, the middle distribution section essentially serves to flush out the siphon. The outlet opening of the left distribution section, in the installed position and seen in the direction of flow of the flushing water, goes off to the left of the flushing water distributor through the outer wall of the flushing water distributor. The outlet opening is designed to wet a left area of the wall of the sanitary article. The outlet opening of the right distribution section goes in the installed position and seen in the direction of flow of the flushing water laterally to the right of the flushing water distributor through the outer wall of the flushing water distributor. The outlet opening is designed to wet a right area of the wall of the sanitary article. The outlet opening of the middle distribution section is designed to flush out the siphon area. The middle distribution section is arranged between the side distribution sections.

In other words, the operation can be shown as follows: The left and the right distribution section are directed in the installed position on the wall of the sanitary article and flow over the wall in the direction of the siphon of the sanitary article. The water provided by these two distribution sections essentially cleans the surfaces of the sanitary article. In the installed position, the middle distribution section, as already mentioned, is directed towards the siphon area of the sanitary article and ensures that the siphon area is flushed out.

With this jet in particular, it is important that it is directed at the siphon area at the largest possible angle, especially at 1⁄2 or 1/3 of the siphon water surface length.

Due to the arrangement of the guide surface, the jet can be throttled in such a way that the optimum flushing performance can be achieved.

Preferably, the front edge, seen in the installed position, runs in a horizontal plane and at right angles to the central axis. The front edge is preferably spaced apart and, viewed in the installed position, below the central axis. The trailing edge preferably runs parallel to the central axis and is closer to the central axis than the leading edge. The guide surface rises in the middle distribution section between the front edge and the rear edge, so that the cross-sectional area decreases as the distance from the front edge increases.

Preferably, the guide surface has a first portion which rises from the front edge at an angle to the central axis at an angle. The inclination is such that the cross-sectional area of the central distribution section decreases as the distance from the front edge increases. With a guide surface arranged at an angle, there is the advantage of a throttling that is gentle on the flow.

The angle is preferably in the range from 5 ° to 30 °, in particular in the range from 5 ° to 20 °.

The first section extends from the bottom to the top as seen in the installed position. This means that the front edge lies below the rear edge when viewed in the installation position. The first section represents a kind of ramp for the flushing water, the flushing water being deflected upwards from the central axis as seen in the installation position.

Preferably, the guide surface further has a second section which adjoins the first section and ends with the rear edge, wherein the second section with its surface facing the central distribution section runs parallel to the central axis, and the surface is preferably at the level of the Central axis lies. The rear edge preferably intersects the central axis.

The formation of the second section parallel to the central axis and thus also parallel to the general direction of flow has the advantage that the flow can calm down in the area of the second section.

The surfaces overflowing the guide surface, in particular the overflowing surfaces from the first section and from the second section, are preferably designed as flat surfaces.

[0019] The front edge preferably extends completely through the flushing water channel, seen transversely to the central axis. The guide surface extends upward into the flushing water channel when viewed from the front edge in the installed position. A transverse wall extends from the leading edge downwards to the inner wall. Due to the transverse wall, the guide surface can be arranged at a smaller distance from the central axis, as a result of which the throttling effect can be increased.

Preferably, the right distribution section and the left distribution section are seen in the installed position above the transverse wall. The front edge preferably forms the lower limit of the right and left distribution sections.

Preferably, an opening is arranged in the transverse wall which, viewed in the installation position, extends to the lowest point of the inner wall, so that any residual water that remains in the flushing water channel in front of the transverse wall after a flushing process can flow out of the flushing water channel.

[0022] The transverse wall is preferably adjoined below the guide surface by a residual water channel, the residual water channel opening into the central distribution section. Residual water can be led away from the opening via the residual water channel. The residual water channel preferably has a groove which extends from the opening in the direction of flow.

The outflow of residual water can be improved with the groove. In particular, a type of capillary effect can be achieved in the groove, which promotes the drainage of the residual water in the direction of the outlet opening.

Preferably, the cross-sectional area of the opening, viewed in the direction of flow, is significantly smaller than the cross-sectional area of the distribution sections. Substantially smaller is understood to mean, for example, that the cross-sectional area of the opening is less than 10% or 20% of the cross-sectional area of the distribution sections. The cross-sectional area is preferably the area determining the cross-section in the area of the front edge, seen transversely to the central axis.

Preferably, the middle distribution section is further delimited by a deflection surface arranged above the guide surface and by two lateral guide surfaces, the lateral guide surfaces connecting the guide surface and the deflection surface to one another.

In other words, the middle distribution section is provided or circumferentially limited by the guide surface, the two lateral guide surfaces and the deflection surface.

Preferably, the cross-sectional area of the central distribution section or channel delimited by the guide surface, the deflection surface and the two lateral guide surfaces becomes smaller with an increasing distance, seen from the front edge in the direction of flow, at least as far as the rear edge.

The cross-sectional area is accordingly smaller from the front edge to the rear edge. After the rear edge, the cross-sectional area can be smaller or larger again.

Preferably, the distance between the lateral guide surfaces in the direction of the flow direction increases as the distance from the front edge increases.

Preferably, in cross section, viewed transversely to the central axis, the deflecting surface is curved downward in the installed position and / or is designed to be inclined downward at an angle. The deflection surface preferably extends from above the front edge to below the central axis, in particular to the lowest point of the inner wall.

Particularly preferably, the deflection surface extends at most up to a geometric enveloping circle, which forms the continuation of the outer wall, and at least at least up to the central axis. This arrangement of the deflecting surface has the advantage that the water jet from the central distribution section is guided as long as possible, which in turn is conducive to the precision of the water jet into the sanitary article.

The guide surface is preferably directed towards the deflection surface.

Preferably, the cross-sectional area of the middle distribution section at the level of the front edge is larger than the cross-section of the left and / or right distribution section.

The flushing water distributor is preferably provided by a pipe element and by an insert element, wherein the guide surface is part of the pipe element and wherein the separating part and the distribution sections are provided by the insert element.

The insert element and the tubular element are preferably connected to one another via a longitudinal guide in such a way that the insert element can be pushed into the tubular element and that the insert element is held mechanically in the tubular element via a latching connection between the insert element and the tubular element.

A sanitary article, in particular a toilet bowl or a urinal, comprises a receptacle for a flush water distributor and a wall and a siphon area, the flush water distributor being insertable into the receptacle in such a way that the middle distribution section is directed towards the siphon area.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures, an embodiment of a flush water distributor 1 for a sanitary article 2, such as a toilet bowl or a urinal is shown. The rinsing water distributor 1 comprises an outer wall 3 extending around a central axis M with an inner wall 5 directed towards a rinsing water channel 4. On the outside, the rinsing water distributor 1 also comprises a bearing point 28 which is surrounded by a seal 29. The flushing water distributor 1 can be stored in a correspondingly designed receptacle 30 in the sanitary article 2 via the bearing point 28 and the seal 29. The storage is shown in FIG.

In FIG. 2, the flushing water distributor 1 is shown in an exploded view. The flushing water distributor 1 can be provided from a pipe element 23 and an insert element 24. The insert element 24 can be inserted into the tubular element 23. For the connection, the tubular element 23 and the insert element 24 have a longitudinal guide 25 which is designed such that the insert element 24 can be pushed into the tubular element 23. To secure the insert element 24 in the tubular element 23, a latching connection 26 is provided between the two parts. However, it is also possible for the flushing water distributor 1 to be designed in one piece.

Figures 3 to 4 show side views or sectional views of the flushing water distributor 1. The flushing water distributor 1 comprises a separating part 6 in the flushing water channel 4, which divides the flushing water channel 4 in the front area into a right distribution section 7, a left distribution section 8 and a central distribution section 9 divides. The middle distribution section 9 lies between the right distribution section 7 and the left distribution section 8. Each of the distribution sections 7, 8, 9 has an outlet opening 10 through which the flushing water from the flushing water channel 4 or the respective distribution section 7, 8, 9 is Sanitary article 2 can be delivered. Opposite the outlet openings 10, the flushing water channel 4 has an inlet opening 31, and flushing water can enter the flushing water channel 4 via the inlet opening 31. The inlet opening 31 is preferably designed in such a way that a flushing pipe 34 protrudes into the inlet opening 31.

The middle distribution section 9 will now be explained in more detail with reference to FIG. The middle distribution section 9 comprises a guide surface 11 with a front edge 12 and a rear edge 13. The front edge 12 lies in front of the rear edge 13, seen in the direction of flow F of the flushing water. The guide surface 11 is arranged in the middle distribution section 9 in such a way that the flow in the middle Distribution section 9 experiences a throttling in the area of the guide surface 11. This means that the flushing water flow is correspondingly throttled in the middle distribution section 9.

In the embodiments shown, the guide surface 11 has two sections 14, 15. A first section 14 extends from the front edge 12 at an angle α at an angle to the central axis M. The second section 15, which adjoins the first section 14, is oriented essentially parallel to the central axis M. The orientation with respect to the angle and the parallelism relates in each case in a direction seen transversely to the central axis, as shown in FIG. In the embodiment shown, the second section 15 runs with its surface 16 facing the central distribution section 9 parallel to the central axis M. The surface 16 lies essentially at the level of the central axis M.

The front edge 12 extends, as shown in FIGS. 4 to 7, transversely to the central axis M completely through the flushing water channel 4. The guide surface 11 extends upwards when viewed from the front edge 12 in the installed position. A transverse wall 17 further extends from the leading edge 12 downwards to the inner wall 5. This transverse wall 17 extends essentially at right angles to the central axis M. The transverse wall 17 closes the area below the leading edge 12, apart from one Opening 18, which will be explained further below, essentially completely. From the projection representation in FIG. 7 it can be clearly seen that the right distribution section 7 and the left distribution section 8 each lie above the transverse wall 17. In the transverse wall 17 there is also an opening 18 which, viewed in the installed position, extends down to the deepest point 19 in the inner wall 5. Corresponding residual water lying in the flushing water channel can flow out of the flushing water channel 4 via the opening 18. This can be seen well in FIG. The remaining water is in front of and / or after the transverse wall 17 as seen in the direction of flow F. The remaining water can flow through the opening 18 through the transverse wall 17 and then flows off towards the front. Furthermore, a groove 20 is arranged at the deepest area. The groove 20, which adjoins the transverse wall 17 or the opening 18 in the direction of flow, extends to an outlet opening 10, here essentially to the outlet opening 10 of the central distribution section 9.

As shown in FIGS. 5 and 6, the middle distribution section 9 has a deflection surface 21 and two lateral guide surfaces 22. The two lateral guide surfaces 22 extend upwards from the guide surface 11 and the deflection surface 21 extends between the two guide surfaces 22 at a distance from the guide surface 11. This forms a corresponding channel. The cross section, which is delimited by the guide surface 11, the deflection surface 21 and the two lateral guide surfaces 22, decreases as the direction of flow increases, viewed from the front edge 12. That is to say, the cross section becomes smaller over the length of the guide surface 11 along the flow direction F. This allows the corresponding throttling to be achieved. After the rear edge 13, the cross section opens again and the deflection surface 21 and the lateral guide surfaces 22 direct the flushing water jet accordingly into the siphon area.

In the embodiment shown, the deflecting surface 21 is curved downwards in the installed position and is designed to be inclined downwards at an angle. In this case, the deflecting surface 21 extends in cross-section transversely to the central axis from the height of the front edge 12 to below the central axis M. In the figures, the deflecting surface 21 extends to the lowest point of the inner wall 5. This design, which is shown well in FIG can be recognized, ensures an optimal introduction of the flushing water jet into the siphon area.

The cross section of the opening 18 seen in the direction of flow is, as shown in Figure 7, much smaller than the cross section of the distribution sections 7, 8, 9. This has the advantage that only an extremely small amount of rinsing water through the opening 18 flows through it. More than 90% of the rinsing water is preferably routed through the distribution sections 7, 8, 9.

It can also be clearly seen from FIG. 7 that the cross-sectional area of the middle distribution section 9 at the level of the front edge 12 is larger than the cross-sectional area of the left and / or right distribution section 7, 8.

In the embodiment shown, as has already been explained above with reference to FIG. 2, the flushing water distributor 1 is provided by two parts, namely by a pipe element 23 and by an insert element 24. The guide surface 11 is part of the pipe element 23. The separating part 6 and the distribution sections 7, 8, 9 are provided by the insert element 24.

In FIG. 6 it is also shown that the flushing water distributor 1, which is located in a receptacle 27 on the sanitary article 2, can be directed mechanically to the sanitary article via a securing element 32. The position and / or the location of the flushing water distributor 1 in the sanitary article 2 is determined.
