Description

Technical Field

[0001] The invention relates to a flushing water distributor. Background Art

[0002] In sanitary ware, in particular ceramic sanitary ware, flushing water distributors are installed in the sanitary ware to better distribute the flushing water. For example, DE 33 15 926 discloses such a flushing water distributor. 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] However, DE 33 15 926 has the disadvantage that the intermediate flushing water flow is not guided in a favorable manner, in particular with regard to the siphon flushing properties. Summary of the invention

[0004] Based on this prior art, the object of the present invention is to provide a flushing water distributor which overcomes the disadvantages of the prior art, in particular to provide a flushing water distributor which has good siphon flushing properties and preferably provides good flushing of ceramic surfaces.

[0005] A flushing water distributor for sanitary ware such as a toilet or a urinal comprises an outer wall extending around a central axis, the outer wall having an inner wall oriented toward a flushing water channel; a separation component at least partially located in the flushing water channel, the separation component dividing the flushing 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 delivered to the flushing water channel. Each of the distribution sections has an outlet opening, via which flushing water can be output into the sanitary ware. The flushing water can be guided from the inlet opening to the distribution section and its outlet opening in the flow direction. The middle distribution section has a guide surface with a leading edge and a trailing edge, the guide surface being arranged in the middle distribution section so that the water flow in the middle distribution section is throttled or can be throttled in the region of the guide surface.

[0006] The throttling of the flushing water flow in the middle distribution section has the advantage that the flushing of the siphon area can be improved. In this case, the flushing water jet from the middle distribution section is sprayed onto the siphon area in a throttled manner. In this case, throttling is particularly advantageous for flushing light and soft materials such as toilet paper.

[0007] Furthermore, the guide surface has the advantage that the water is guided in the throttling region via a certain guide path, ie, along the entire length of the guide surface when viewed in the flow direction, thereby being able to guide or smooth the water flow in the throttling element without generating large eddies.

[0008] As mentioned, the central distribution section is primarily used for flushing the siphon. Viewed in the installed position and in the flow direction of the flushing water, the outlet opening of the left-hand distribution section exits the flushing water distributor laterally through the outer wall on the left side of the flushing water distributor. Here, the outlet opening is designed for wetting the left-hand area of ​​the sanitary ware wall. Viewed in the installed position and in the flow direction of the flushing water, the outlet opening of the right-hand distribution section exits the flushing water distributor laterally through the outer wall on the right side of the flushing water distributor. Here, the outlet opening is designed for wetting the right-hand area of ​​the sanitary ware wall. The outlet opening of the central distribution section is designed for flushing the siphon area. The central distribution section is arranged between the lateral distribution sections.

[0009] In other words, the operating principle can be described as follows: The left and right distribution sections are oriented to the sanitary ware wall in the installed position and flow through the wall in the direction of the siphon of the sanitary ware. The water provided by the two distribution sections primarily cleans the surfaces of the sanitary ware. As already explained, the middle distribution section is oriented to the siphon area of ​​the sanitary ware in the installed position and is used for flushing the siphon area.

[0010] Especially with this type of jet it is important to direct the jet at the largest possible angle into the siphon area, especially at 1 / 2 or 1 / 3 of the length of the siphon water surface.

[0011] By providing the guide surface, the jet can be throttled until an optimal flushing performance can be achieved.

[0012] The leading edge preferably extends perpendicularly to the central axis in a horizontal plane when viewed in the installed position. The leading edge is preferably spaced apart and, when viewed in the installed position, is located below the central axis. The trailing edge preferably extends parallel to the central axis and is closer to the central axis than the leading edge. In the middle distribution section, the guide surface rises between the leading edge and the trailing edge, so that the cross-sectional area decreases as the distance increases, viewed from the leading edge.

[0013] Preferably, the guide surface has a first section which rises at an angle from the front edge at an angle to the central axis. The inclination is such that the cross-sectional area of ​​the central distribution section decreases with increasing spacing, as viewed from the front edge. The guide surface arranged at an angle has the advantage that the water flow is throttled gently.

[0014] Preferably, the angle is in the range of 5° to 30°, in particular in the range of 5° to 20°.

[0015] When viewed in the installed position, the first section extends from bottom to top. This means that when viewed in the installed position, the front edge is located below the rear edge. For the flushing water, the first section represents a kind of slope, wherein, when viewed in the installed position, the flushing water is deflected upward from the central axis.

[0016] Preferably, the guide surface also has a second section, which adjoins the first section and ends at a trailing edge, wherein the second section extends with its surface facing the intermediate distribution section parallel to the central axis and wherein the surface is preferably located at the height of the central axis. In this case, the trailing edge preferably intersects the central axis.

[0017] By configuring the second section parallel to the central axis and thus also parallel to the overall flow direction, the advantage is achieved that the water flow can be calmed down in the region of the second section.

[0018] Preferably, the overflow surfaces of the guide surface, in particular the overflow surfaces of the first section and the second section, are designed as planar surfaces.

[0019] The front edge preferably extends completely through the flushing water channel when viewed transversely to the central axis. The guide surface extends upwards into the flushing water channel in the installed position when viewed from the front edge. The transverse wall extends downwards from the front edge to the inner wall. The transverse wall makes it possible to arrange the guide surface at a smaller distance from the central axis, thereby increasing the throttling effect.

[0020] Preferably, the right and left distribution sections are located above the transverse wall when viewed in the installed position. Preferably, the front edge forms the lower boundary of the right and left distribution sections.

[0021] Preferably, an opening is provided in the transverse wall which, viewed in the installed position, extends as far as the lowest point of the inner wall so that any residual water remaining in the flushing channel upstream of the transverse wall after the flushing process can flow out of the flushing water channel.

[0022] Preferably, the residual water channel adjoins the transverse wall below the guide surface, wherein the residual water channel opens into the middle 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.

[0023] The outflow of residual water can be improved by the groove. In particular, a capillary effect can be achieved in the groove, which helps the residual water to flow out towards the outlet opening.

[0024] Preferably, the cross-sectional area of ​​the opening is significantly smaller than the cross-sectional area of ​​the distribution section when viewed in the flow direction. "Significantly smaller" is understood, for example, to mean that the cross-sectional area of ​​the opening is less than 10% or 20% of the cross-sectional area of ​​the distribution section. The cross-sectional area is preferably the area determined by the cross section in the front edge region when viewed transversely to the center axis.

[0025] The central distributing section is preferably also delimited by a deflection surface arranged above the guide surface and by two lateral guide surfaces, wherein the lateral guide surfaces connect the guide surface and the deflection surface to one another.

[0026] In other words, the central distributing section is provided or is delimited by the guide surface, the two lateral guide surfaces and the deflecting surface.

[0027] The cross-sectional area of ​​the central distribution section or the channel, which is bounded by the guide surface, the deflection surface and the two lateral guide surfaces, preferably decreases with increasing distance in the flow direction, at least as far as the trailing edge, viewed from the leading edge.

[0028] Therefore, the cross-sectional area decreases from the leading edge to the trailing edge. After the trailing edge, the cross-sectional area can decrease or can also increase again.

[0029] Preferably, the distance between the lateral guide surfaces increases along the flow direction as the distance from the leading edge increases.

[0030] Preferably, the deflection surface is configured to be bent downward and / or tilted at an angle downward in the installed position when viewed in a cross section transverse to the center axis. 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.

[0031] Particularly preferably, the deflection surface extends at most to a geometrical envelope circle which forms a continuation of the outer wall and at least to the central axis. Such an arrangement of the deflection surface has the advantage that the water jet from the central distribution section is guided as long as possible, which in turn promotes the precision of the water jet entering the sanitary ware.

[0032] Preferably, the guide surface is oriented onto the deflection surface.

[0033] The cross-sectional area of ​​the central distribution section, viewed at the height of the leading edge, is preferably greater than the cross-sectional area of ​​the left-hand distribution section and / or the right-hand distribution section.

[0034] Preferably, the flushing water distributor is provided by a pipe element and by an insertion element, wherein the guide surface is part of the pipe element and wherein the separating part and the distribution section are provided by the insertion element.

[0035] Preferably, the insertion element and the tube element are connected to one another via a longitudinal guide, so that the insertion element can be pushed into the tube element and is mechanically held in the tube element via a locking connection between the insertion element and the tube element.

[0036] The sanitary appliance, in particular a toilet or a urinal, comprises a receptacle for a flushing water distributor as well as a wall and a siphon region, wherein the flushing water distributor can be inserted into the receptacle such that a central distribution section is oriented in the direction of the siphon region.

[0045] The figures show an embodiment of a flushing water distributor 1 for a sanitary ware 2, such as a toilet or a urinal. The flushing water distributor 1 comprises an outer wall 3 extending around a central axis M, which has an inner wall 5 oriented toward a flushing water channel 4. The flushing water distributor 1 also comprises a support 28 on the outside, which is surrounded by a seal 29. The flushing water distributor 1 can be supported in a correspondingly configured receptacle 30 in the sanitary ware 2 by means of the support 28 and the seal 29. The support in Figure 6 Shown in.

[0046] exist Figure 22 shows an exploded view of a flushing water distributor 1. The flushing water distributor 1 can be provided by a pipe element 23 and an insertion element 24. Here, the insertion element 24 can be inserted into the pipe element 23. For connection, the pipe element 23 and the insertion element 24 have a longitudinal guide 25, which is designed so that the insertion element 24 can be pushed into the pipe element 23. In order to lock the insertion element 24 in the pipe element 23, a locking connection 26 is provided between the two components. However, it is also possible that the flushing water distributor 1 is formed in one piece.

[0047] Figures 3 to 4 A side view or a sectional view of a flushing water distributor 1 is shown. In the flushing water channel 4, the flushing water distributor 1 comprises a separation component 6, which in the front region divides the flushing water channel 4 into a right distribution section 7, a left distribution section 8 and a middle distribution section 9. Here, the middle distribution section 9 is located between the right distribution section 7 and the left distribution section 8. Each of the distribution sections has an outlet opening 10, through which the flushing water in the flushing water channel 4 or the corresponding distribution section can be output to the sanitary ware 2. Relative to the outlet opening 10, the flushing water channel 4 has an inlet opening 31, through which the flushing water can enter the flushing water channel 4. Here, the inlet opening 31 is preferably configured so that the flushing pipe 34 extends into the inlet opening 31.

[0048] Now, according to Figure 4 The central distribution section 9 is explained in more detail. The central distribution section 9 comprises a guide surface 11 having a front edge 12 and a rear edge 13. Viewed in the flow direction F of the flushing water, the front edge 12 is located here before the rear edge 13. The guide surface 11 is arranged in the central distribution section 9 so that the water flow in the central distribution section 9 is throttled in the region of the guide surface 11. This means that the flushing water flow is throttled accordingly in the central distribution section 9.

[0049] In the embodiment shown, the guide surface 11 has two sections, a first section 14 and a second section 15. The first section 14 extends obliquely from the front edge 12 at an angle α toward the center axis M. The second section 15 adjoining the first section 14 is oriented substantially parallel to the center axis M. The orientation with respect to angles and parallelism refers to the direction of the axis viewed transversely to the center axis and in the direction of the center axis. Figure 4 In the embodiment shown, the second section 15 extends with its surface 16 facing the central distributing section 9 parallel to the center axis M. The surface 16 is located substantially at the height of the center axis M.

[0050] like Figures 4 to 7As shown, the front edge 12 extends completely through the flushing water channel 4 transversely to the center axis M. Here, the guide surface 11 extends upward in the installed position, viewed from the front edge 12. In addition, a transverse wall 17 extends downward from the front edge 12 to the inner wall 5. The transverse wall 17 extends essentially perpendicularly to the center axis M. Here, with the exception of the opening 18 described further below, the transverse wall 17 essentially completely closes the area below the front edge 12. Figure 7 It can be clearly seen in the projection view that the right distribution section 7 and the left distribution section 8 are respectively located on the transverse wall 17.

[0051] An opening 18 is also provided in the transverse wall 17, which, viewed in the installed position, extends to a lowest point 19 in the inner wall 5. Residual water located in the flushing water channel can accordingly flow out of the flushing water channel 4 via the opening 18. This Figure 6 1. As can be seen clearly in FIG. 1 . Viewed in the flow direction F, the residual water is located in front of and / or behind the transverse wall 17. The residual water can flow through the transverse wall 17 via the opening 18 and then flow out toward the front. In addition, a groove 20 is provided at the lowest area. The groove 20, which is connected to the transverse wall 17 or the opening 18 in the flow direction, extends to the outlet opening 10, here mainly to the outlet opening 10 of the middle distribution section 9.

[0052] As in Figure 5 and 6 As shown in , the middle distribution section 9 has a deflection surface 21 and two lateral guide surfaces 22. The two lateral guide surfaces 22 extend upward from the guide surface 11 and the deflection surface 21 extends between the two lateral guide surfaces 22 spaced apart from the guide surface 11. Thus, a corresponding channel is formed. Observed from the leading edge 12, the cross section defined by the guide surface 11, the deflection surface 21 and the two lateral guide surfaces 22 decreases as the distance from the leading edge 12 along the flow direction increases. That is to say, observed along the flow direction F, the cross section gradually becomes smaller over the entire length of the guide surface 11. Thus, corresponding throttling can be achieved. After the trailing edge 13, the cross section is open again and the deflection surface 21 and the lateral guide surface 22 direct the flushing water jet accordingly into the siphon area.

[0053] In the embodiment shown, the deflection surface 21 is designed to bend downward in the installed position and to be inclined downward at an angle. Here, when viewed in a cross section transverse to the center axis, the deflection surface 21 extends from the height of the front edge 12 to below the center axis M. In the figure, the deflection surface 21 extends to the lowest point of the inner wall 5. Figure 4 It can be clearly seen in FIG. 1 that this design is used to optimally guide the flushing water jet into the region of the siphon.

[0054] As in Figure 7As shown in , the cross section of the opening 18, viewed in the flow direction, is significantly smaller than the cross section of the distribution section. This results in the advantage that 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.

[0055] In addition, from Figure 7 It can be clearly seen in FIG. 1 that the cross section of the central distributing section 9 , viewed at the height of the front edge 12 , is larger than the cross section of the left and / or right distributing section 7 , 8 .

[0056] In the embodiment shown, as already described above according to Figure 2 As explained, the flushing water distributor 1 is provided in two parts, namely by the tube element 23 and by the insertion element 24. The guide surface 11 is part of the tube element 23. The separating element 6 and the distribution section are provided by the insertion element 24.

[0057] exist Figure 6 It is also shown in FIG. 2 that the flushing water distributor 1 located in the receptacle 27 of the sanitary ware 2 can be mechanically locked relative to the sanitary ware via a locking element 32. Thus, the position and / or orientation of the flushing water distributor 1 in the sanitary ware 2 is determined.
