Description

Flushing water dispenser

Technical Field

The present invention relates to a rinsing water dispenser according to the preamble of claim 1.

Background

In sanitary ware, in particular ceramic, a flush water dispenser is incorporated into the sanitary ware for better dispensing of the flush water. For example, DE 3315926 discloses one such rinsing water dispenser. Three flushing water flows are provided, wherein two flushing water flows each flow laterally into the toilet, and wherein one flushing water flow flows straight into the toilet.

However, DE 3315926 has the disadvantages that: the intermediate flushing water flow is disadvantageously directed. Especially in terms of siphon flush performance.

Disclosure of Invention

Based on this prior art, the object on which the invention is based is to propose a rinsing water dispenser which overcomes the disadvantages of the prior art. In particular, a rinsing water distributor is proposed which has good siphon rinsing properties and preferably provides good ceramic surface rinsing.

This object is achieved by the subject matter of claim 1. Accordingly, a flush water dispenser for a sanitary fixture such as a toilet or urinal comprises: an outer wall extending around the central axis, the outer wall having an inner wall oriented toward the flush water passage; a separating element located at least partially in the rinsing water channel, which separating element divides the rinsing water channel into at least one right-hand distribution section, at least one left-hand distribution section and at least one middle distribution section. The flushing water channel has an inlet opening via which flushing water can be fed into the flushing water channel. Each of the dispensing sections has a discharge opening via which flushing water can be output into the sanitary ware. It is possible to guide the flushing water from the inlet opening to the distribution section and its discharge opening in the flow direction. The intermediate distribution section has a guide surface with a leading edge and a trailing edge, which is arranged in the intermediate distribution section such that the water flow in the intermediate distribution section is throttled or can be throttled in the region of the guide surface.

The following advantages are obtained by throttling the flushing water flow in the intermediate distribution section: flushing of the siphon area can be improved. In this case, the flushing water jet from the intermediate distribution section is injected throttled onto the siphon region. The throttling is advantageous here in particular for the flushing of light and soft materials, such as toilet paper.

Furthermore, the guide surface has the advantages of: the water is guided in the throttle region via a certain guide path, i.e. over the entire length of the guide surface, as viewed in the flow direction. This makes it possible to guide or smooth the water flow in the throttle element without generating large eddies.

As mentioned, the intermediate distribution section is mainly used for flushing the siphon. The outlet opening of the left dispensing section, viewed in the loading position and in the flow direction of the rinsing water, exits the rinsing water distributor laterally through the outer wall on the left side of the rinsing water distributor. Here, the discharge opening is configured for wetting a left-hand region of the sanitary ware wall. The outlet opening of the right-hand distribution section, viewed in the loading position and in the direction of flow of the rinsing water, leaves the rinsing water distributor laterally through the outer wall on the right-hand side of the rinsing water distributor. Here, the discharge opening is configured for wetting a right-hand area of the sanitary ware wall. The discharge opening of the intermediate distribution section is configured for flushing the siphon region. The intermediate distribution section is arranged between the lateral distribution sections.

In other words, the working principle can be described as follows: the left and right dispensing sections are oriented onto the sanitary fixture wall in the loading position and flow via the wall in the direction of the siphon of the sanitary fixture. The water provided by the two dispensing sections primarily cleans the surface of the item of sanitary ware. As already explained, the intermediate dispensing section is directed onto the siphon region of the sanitary fitting in the installed position and is used for flushing the siphon region.

Especially for such jets, it is important to direct the jet at the largest possible angle to the siphon region, especially at 1/2 or 1/3 of the length of the siphon water surface.

By providing a guide surface, the jet can be throttled until an optimum flushing performance can be achieved.

Viewed in the installed position, the front edge preferably extends perpendicular to the central axis in a horizontal plane. The front edge is preferably spaced apart and, viewed in the installed position, lies below the center axis. The trailing edge preferably extends parallel to the central axis and is closer to the central axis than the leading edge. In the intermediate distribution section, the guide surface rises between the leading edge and the trailing edge such that the cross-sectional area, viewed from the leading edge, decreases with increasing spacing.

Preferably, the guide surface has a first section which rises obliquely at an angle from the front edge at an angle to the center axis. Here, the inclination is such that the cross-sectional area of the intermediate distribution section decreases with increasing spacing, viewed from the leading edge. The advantage of the guide surface, which is arranged at an angle, is that the water flow is throttled gently.

Preferably, the angle is in the range of 5 ° to 30 °, in particular in the range of 5 ° to 20 °.

Viewed in the installed position, the first section extends from the bottom to the top. That is to say that the leading edge is located below the trailing edge, viewed in the installed position. The first section means an inclined plane for the rinsing water, wherein the rinsing water is deflected upward from the center axis, as viewed in the installed position.

Preferably, the guide surface also has a second section which adjoins the first section and ends at the rear edge, wherein the second section extends with its surface facing the central distribution section parallel to the center axis, and wherein the surface is preferably located at the level of the center axis. In this case, the trailing edge preferably intersects the central axis.

By configuring the second portion parallel to the center axis and thus also parallel to the overall flow direction, the following advantages result: the water flow can be smoothed out in the region of the second section.

The overflow surface of the guide surface, in particular of the first and second sections, is preferably designed as a flat surface.

Viewed transversely to the central axis, the front edge preferably extends completely through the rinsing water channel. The guide surface extends, as viewed from the front edge, in the installed position up into the rinsing water channel. The transverse wall extends downwardly from the leading edge to the inner wall. By means of the transverse wall, the guide surface can be arranged at a smaller distance from the centre axis, whereby the throttling effect can be increased.

Preferably, the right-hand dispensing section and the left-hand dispensing section are located above the transverse wall, viewed in the installed position. Preferably, the leading edge forms the lower boundary of the right and left side dispensing sections.

Preferably, an opening is provided in the transverse wall, which opening, viewed in the installed position, extends up to the lowest position of the inner wall, so that possible residual water remaining in the flushing channel before the transverse wall after a flushing process can flow out of the flushing water channel.

Preferably, the residual water channel adjoins the transverse wall below the guide surface, wherein the residual water channel opens into the intermediate distribution section. The residual water can be guided out of the opening via the residual water channel. The residual water channel preferably has a groove extending from the opening in the flow direction.

The outflow of the residual water can be improved by the grooves. In particular, a capillary effect can be achieved in the grooves, which capillary effect contributes to the outflow of residual water towards the discharge opening.

Preferably, the cross-sectional area of the opening, viewed in the flow direction, is significantly smaller than the cross-sectional area of the dispensing section. "significantly less than" is understood, for example, as: the cross-sectional area of the opening is less than 10% or 20% of the cross-sectional area of the dispensing section. The cross-sectional area is preferably the area determined by the cross-section in the leading edge region, viewed transversely to the central axis.

Preferably, the intermediate dispensing section is also delimited by a deflecting surface arranged above the guide surface and by two lateral guide surfaces, wherein the lateral guide surfaces connect the guide surface and the deflecting surface to one another.

In other words, the intermediate distribution section is provided by or bounded around the guide surface, the two lateral guide surfaces and the deflection surface.

The cross-sectional area of the intermediate distribution section or channel, which is delimited by the guide surface, the deflection surface and the two lateral guide surfaces, viewed from the leading edge, preferably decreases with increasing distance in the flow direction, at least up to the trailing edge.

Thus, the cross-sectional area decreases from the leading edge to the trailing edge. After the trailing edge, the cross-sectional area can be smaller or, however, can also be larger again.

Preferably, the distance between the lateral guiding surfaces becomes larger with increasing distance from the leading edge in the flow direction.

Preferably, the deflection surface is configured, viewed in a cross-section transverse to the center axis, to curve downward and/or to be inclined at an angle downward in the installed position. Preferably, the deflection surface extends from above the front edge to below the center axis, in particular to the lowest point of the inner wall.

Particularly preferably, the deflection surface extends up to a geometric envelope circle which forms a continuation of the outer wall and at least up to the central axis. This arrangement of the deflection surfaces has the advantage that: providing as long a guide as possible for the water jet from the intermediate distribution section, which in turn promotes the precision of the water jet entering the sanitary ware.

Preferably, the guide surface is oriented onto the deflection surface.

The cross-sectional area of the middle distribution section, viewed at the height of the leading edge, is preferably larger than the cross-sectional area of the left-hand distribution section and/or the right-hand distribution section.

Preferably, the rinsing water distributor is provided by the pipe element and by the insertion element, wherein the guide surface is part of the pipe element, and wherein the separating member and the distribution section are provided by the insertion element.

Preferably, the insertion element and the tube element are connected to one another via a longitudinal guide such that the insertion element can be pushed into the tube element and the insertion element is mechanically held in the tube element via a locking connection between the insertion element and the tube element.

The sanitary device, in particular a toilet or urinal, comprises a receptacle for a rinsing water distributor and a wall and a siphon region, wherein the rinsing water distributor can be inserted into the receptacle such that the intermediate distribution section is oriented in the direction of the siphon region.

Further embodiments are given in the dependent claims.

Detailed Description

In the drawings there is shown an embodiment of a flush water dispenser 1 for a sanitary ware 2 such as a toilet or urinal. The rinsing water distributor 1 comprises an outer wall 3 which extends around a central axis M and has an inner wall 5 which is oriented toward the rinsing water channel 4. The rinsing water dispenser 1 also comprises a bearing 28 on the outside, which is surrounded by a seal 29. The flush water dispenser 1 can be supported in a correspondingly configured receptacle 30 in the sanitary fitting 2 by means of the support 28 and the seal 29. The support is shown in fig. 6.

Fig. 2 shows an exploded view of the rinsing water dispenser 1. The rinsing water dispenser 1 can be provided by a pipe element 23 and a loading element 24. The insertion element 24 can be inserted into the tube element 23. For the connection, the tube element 23 and the insertion element 24 have longitudinal guides 25 which are configured such that the insertion element 24 can be pushed into the tube element 23. In order to lock the insertion element 24 in the tube element 23, a locking connection 26 is provided between the two parts. However, it is also possible for the rinsing water dispenser 1 to be formed in one piece.

Fig. 3 to 4 show a side view or a sectional view of the flush water dispenser 1. In the flushing water channel 4, the flushing water distributor 1 comprises a separating member 6 which divides the flushing water channel 4 into a right-hand distributing section 7, a left-hand distributing section 8 and an intermediate distributing section 9 in the front region. The middle distribution section 9 is located between the right distribution section 7 and the left distribution section 8. Each of the

distribution sections

7, 8, 9 has a discharge opening 10 via which rinsing water in the rinsing water channel 4 or in the

respective distribution section

7, 8, 9 can be discharged into the sanitary fixture 2. With respect to the discharge opening 10, the flushing water channel 4 has an inlet opening 31, via which inlet opening 31 flushing water can enter the flushing water channel 4. Here, the inlet opening 31 is preferably configured such that the flushing pipe 34 projects into the inlet opening 31.

The intermediate distribution section 9 will now be explained in more detail with reference to fig. 4. The intermediate distribution section 9 comprises a guide surface 11 having a leading edge 12 and a trailing edge 13. The leading edge 12 is here located before the trailing edge 13, viewed in the flow direction F of the rinsing water. The guide surface 11 is arranged in the intermediate distribution section 9, so that the water flow in the intermediate distribution section 9 is throttled in the region of the guide surface 11. That is to say that the flushing water flow is throttled accordingly in the intermediate distribution section 9.

In the embodiment shown, the guide surface 11 has two

sections

14, 15. The first end 14 extends obliquely from the front edge 12 towards the middle axis M at an angle a. The second portion 15 adjoining the first portion 14 is oriented substantially parallel to the center axis M. The orientations with respect to angle and parallelism relate to the directions viewed transversely to the central axis and shown in fig. 4, respectively. In the embodiment shown, the second portion 15 extends with its surface 16 facing the intermediate distributor portion 9 parallel to the central axis M. The surface 16 is here situated substantially at the level of the central axis M.

As fig. 4 to 7 show, the front edge 12 extends completely through the flushing water channel 4 transversely to the center axis M. The guide surface 11 extends upward from the front edge 12 along the installation position. Furthermore, a transverse wall 17 extends downwards from the front edge 12 as far as the inner wall 5. The transverse wall 17 extends here substantially perpendicularly to the central axis M. Here, the transverse wall 17 substantially completely closes off the region below the front edge 12, except for an opening 18 which is explained further below. As can best be seen in the projection of fig. 7: the right-hand dispensing section 7 and the left-hand dispensing section 8 are each located above a transverse wall 17.

An opening 18 is also provided in the transverse wall 17, which opening, viewed in the installed position, extends up to a lowest position 19 in the inner wall 5. The residual water located in the flushing water channel can accordingly flow out of the flushing water channel 4 via the opening 18. This can be seen best in fig. 6. Viewed in the flow direction F, the residual water is located in front of and/or behind the transverse wall 17, respectively. The residual water can flow through the transverse wall 17 through the openings 18 and then flow out towards the front. Furthermore, a groove 20 is provided at the lowermost region. Extends via a groove 20, which is connected in the flow direction to the transverse wall 17 or the opening 18, up to the discharge opening 10, in this case mainly up to the discharge opening 10 of the intermediate distributor section 9.

As shown in fig. 5 and 6, the intermediate distribution section 9 has a deflection surface 21 and two lateral guide surfaces 22. The two lateral guide surfaces 22 extend here upwards from the guide surface 11 and the deflection surface 21 extends between the two guide surfaces 22 spaced apart from the guide surface 11. Thereby, a corresponding channel is formed. The cross section defined by the guide surface 11, the deflection surface 21 and the two lateral guide surfaces 22 decreases with increasing distance from the leading edge 12 in the flow direction, viewed from the leading edge 12. That is to say that the cross section, viewed in the flow direction F, tapers over the entire length of the guide surface 11. Thereby, a corresponding throttling can be achieved. After the trailing edge 13, the cross section opens again and the deflection surface 21 and the lateral guide surface 22 direct the flushing water jet accordingly into the siphon area.

In the embodiment shown, the deflection surface 21 is configured to curve downward and to slope angularly downward in the installed position. The deflection surface 21 extends, as viewed in a cross section transverse to the center axis, from the level of the front edge 12 up to below the center axis M. In the figure, the deflection surface 21 extends as far as the lowest point of the inner wall 5. As can be seen well in fig. 4, this embodiment serves to optimally guide the flushing water jet into the siphon region.

As shown in fig. 7, the cross section of the opening 18, viewed in the flow direction, is significantly smaller than the cross section of the dispensing

sections

7, 8, 9. The following advantages are thereby obtained: only a very small amount of flushing water flows through the opening 18. Preferably, more than 90% of the flushing water is guided through the

distribution section

7, 8, 9.

Furthermore, as can be best seen in fig. 7: the cross section of the middle distribution section 9, viewed at the height of the leading edge 12, is greater than the cross section of the left-hand and/or right-

hand distribution sections

7, 8.

In the embodiment shown, the flush water dispenser 1 is provided in two parts, namely by the tube element 23 and by the insertion element 24, as already explained above with reference to fig. 2. The guide surface 11 is here part of the pipe element 23. The separating means 6 and the dispensing

sections

7, 8, 9 are provided by a feed-in element 24.

Fig. 6 also shows that the rinsing water dispenser 1 located in the receptacle 27 of the sanitary fixture 2 can be mechanically locked relative to the sanitary fixture via a locking element 32. Thus, the position and/or orientation of the flush water dispenser 1 in the sanitary fixture 2 is determined.
