STATE OF THE ART

From EP 0 342 723 a drain arrangement has become known in which an overflow pipe is arranged above a valve and provides a bridging of the valve when the water level in the wash basin rises too much. The valve can be raised in the direction of the vertical. A disadvantage of the drainage arrangement of EP 0 342 723 is that due to the design of the drainage arrangement a comparatively large installation space is required below the washstand.

In addition, the seal, which seals the valve on the valve seat, constantly overflowed with open valve with water, which is disadvantageous in terms of their life.

PRESENTATION OF THE INVENTION

Based on this prior art, the invention has for its object to provide a flow arrangement, which overcomes the disadvantages of the prior art. In particular, the drain arrangement should be made more compact. Particularly preferably, the drainage device should be better mountable.

This object is achieved by the subject matter of claim 1. Accordingly, a drain assembly for connection to a sanitary article comprises a drain pipe having a pipe inlet and a pipe outlet, one in a valve portion of the drain pipe arranged valve having a sealing surface and a valve body, wherein the valve body with an actuating element of a sealing position in an Ottenlage of the sealing surface is movable away, and an overflow pipe, which is seen from a lying in the direction of water before the valve first branch point to a in Flow direction of the water after the valve lying second branch point extends away from the drain pipe and thus bridges the valve. The overflow pipe extends in the installed position substantially counter to the direction of the solder upwards. The valve body is at least partially mounted on an insert element. The drainpipe has an insert receptacle, wherein the insert element can be inserted into the insert receptacle on the drainpipe.

The arrangement of the valve body on an insert element has the advantage that the assembly and disassembly of the valve body is simplified.

The expression "that valve body is at least partially mounted on an insert element" is to be understood that the valve body is completely mounted on the insert element or that the valve body is partially supported on the insert element and partially on another element of the arrangement.

The storage is such that the valve body can move relative to the sealing surface.

The bearing of the valve body on the insert element is particularly preferably such that the valve body can be inserted into the drainpipe together with the insert element during an assembly process. The assembly process includes both assembly and disassembly. During disassembly, there is the advantage that due to the bearing of the valve body on the insert element, the valve body with the insert element can be removed from the insert receptacle. As a result, a simple access to the insert element can be created. This is particularly advantageous if the valve body or attached parts need to be cleaned or replaced.

The pipe inlet can be connected to another pipe which is connected to the sanitary article. The tube outlet can be another tube that with the Sewage network communicates.

Preferably, the valve body is a valve flap. The sealing surface is preferably provided by the drain pipe or by the insert element, wherein the valve flap can be pivoted relative to the sealing surface about a geometrical pivot axis. The valve flap is at least partially mounted on the insert receptacle and works with the sealing surface, which is located on the drain pipe, together.

The design of the valve body as a valve flap has the advantage that a simple control and actuation of the valve body is made possible.

The valve flap is mounted on a bearing axis, which is pivotable about the geometric pivot axis. The bearing axis is pivotably mounted in a bearing, in particular in a bearing opening, on the insert element and / or in a bearing, in particular in a bearing opening, on the drain pipe. Next, the bearing axis on a free end which is actuated with said actuating element.

Preferably, the geometric pivot axis or the bearing axis seen in the mounting position on the upper side in the drain pipe. Due to the arrangement of the pivot axis on the upper side has the advantage that the valve flap in the open position is not overflowed by the water flowing through the valve section. As a result, the flow of water is not disturbed by the valve flap, which increases the drainage capacity. In this case, the flow preferably fills the cross section of the valve section to a maximum of 50%.

Preferably, the pivot axis or the bearing axis is oriented in the installed position in the horizontal.

Further, it is preferred that the pivot axis lies in the direction of flow of the water after the sealing surface. Thus, the pivot axis is not in the water when the valve flap is in the closed position.

Particularly preferably, the valve flap comes to lie in its open position in the mouth region of the branch point in the valve section. However, the valve flap does not completely close the mouth region, so that in the case of blocking of the valve flap by foreign substances, a safe overflow through the overflow tube can still be provided.

The insert element preferably has a circular-cylindrical bearing section and the insert receptacle has a circular-cylindrical bearing receiving section, a sealing element is arranged between the bearing section and the bearing-receiving section. With the sealing element is a seal between the insert element and the Insert created so that there no water can escape from the drainage pipe. The circular cylindrical design has the advantage that the assembly and the seal can be made very simple.

Preferably, an orientation structure is arranged between the insert element and the insert receptacle, which aligns the insert receptacle with the valve body mounted in the insert receptacle with respect to the sealing surface. By arranging the orientation structure, the insert element can be placed in the correct position in the insert receptacle. The correct position positioning is advantageous because the valve body is then also arranged in the correct position.

Preferably, the insert element comprises a securing element, which secures the insert element to the drain pipe after the insertion of the insert element into the insert receptacle. The securing element is preferably a purely mechanical securing element, which has no sealing function.

Preferably, the securing element is a lid, which is rotatably mounted on the insert element and which has a thread which cooperates with a correspondingly formed thread on the drain pipe. Preferably, the lid is loosely mounted on the insert element rotatably. Particularly preferably, the cover has a circumferential groove, in which engages a comb of the insert element.

In another variant, the securing element is integrally formed on the insert element and has, for example, the shape of a bayonet closure.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures, a drain assembly 1 for connection to a sanitary article is shown. The sanitary article is typically a vanity.

Figures 1 to 10 show a first embodiment of the drain assembly 1 and the

Figures 11 to 13 show a second embodiment of the drain assembly 1. In the

Sequence will now be with reference to both embodiments of the basic

Structure of the drain assembly 1 explained. The drain arrangement 1 comprises a drain pipe 3 with a pipe inlet 4 and a pipe outlet 5, a valve 7 arranged in a valve section 6 of the drain pipe 3 and an overflow pipe 10. With the overflow pipe 10, the valve 7 is bridged so that in case of unintentional blocking of Valve 7 the water can still abtliessen over the overflow pipe 10 with increasing water level in the sanitary article.

In the valve section 6 of the drain pipe 3, a valve 7 is arranged. The valve 7 comprises a sealing surface 8 and a valve body 9, wherein the valve body 9 is movable with an actuating element 15 from a closed position into an open position of the sealing surface 8. The mobility of the valve body 9 is shown in more detail in the sectional views of Figures 7 and 8. In the figure 7, the valve body 9 is in its open position, that is, it is spaced from the sealing surface 8 and in Figure 8, the valve body 9 is in its closed position, that is, the valve body 9 rests on the sealing surface 8. If the valve body 9 is in the closed position and the water accumulates in the sanitary article, then the water can then also rise in the overflow pipe 10 and drain accordingly via the overflow pipe 10. The valve body 9 further has a seal 46, which seals the valve body 9 with respect to the sealing surface 8.

The overflow pipe 10 extends from a first branch point 1 1 to a second branch point 12. The first branch point 11 is seen in the direction of flow F of the water before the valve 7 and the second branch point 12 is in the direction of flow F of the water after the valve 7. Dabei extends the overflow pipe 10 away from the drain pipe 3 and is oriented in the installed position substantially against the direction of the solder upwards. That is, the overflow pipe 10 extends in the installed position substantially counter to the direction of the solder upwards. The overflow pipe 10 is formed separately from the drain pipe 3 in the two embodiments shown as a separate part. The overflow pipe 3 can be connected to the two branch points 1 1, 12. This is preferably a plug connection, as can be seen from FIGS. 2 and 3. That is, the overflow pipe 10 can be inserted into the two branch points 1 1, 12. A welded connection would also be conceivable. It can be seen from FIGS. 2 and 3 or FIGS. 1 and 12 that the valve body 9 is at least partially mounted on an insert element 13. The insert element 13 can be inserted into an insert receptacle 14. The insert receptacle 14 is part of the drain pipe 3 and projects into the drain pipe 3. Due to the bearing of the valve body 9 on the insert element 13, the valve body 9 can be used together with the insert element 13 in the drain pipe 3 in the valve section 6. The valve body 9 can also be removed with the insert element 13 from the valve section 6, so that, for example, the valve body 9 can be replaced. As a result, the basic installation in the manufacture and the subsequent maintenance of the valve body 9 is simplified.

The valve body 9 is a valve flap in both embodiments. The valve flap 9 is formed pivotable relative to the sealing surface 8 about a geometric pivot axis A. That is, the valve flap 9 can be pivoted about the geometric pivot axis A from the closed position to the open position via a pivoting movement.

For this purpose, the drain pipe 3 on the inside a corresponding paragraph, which provides the sealing surface 8. In the second embodiment according to FIGS. 11 to 13, the sealing surface 8 is provided by the insert element 13 itself. That is, the sealing surface 8 is an integral part of the insert element 13th

In the first embodiment, the valve section 6 extends in the installed position such that the direction of flow F is substantially at an angle inclined to the horizontal H, and that the sealing surface 8 is oriented in the installed position substantially at an angle inclined to the vertical V. This is shown in particular in FIGS. 8 and 9. The angle bears the reference a.

With reference to FIGS. 2 to 10, the mounting of the valve flap 13 according to the first embodiment will now be explained in more detail. The valve flap 13 is mounted on a bearing axis 16. The bearing shaft 16 is mounted in a bearing 17, here in a bearing opening 17, the insert member 13 accordingly. The bearing axis 16 extends through the bearing opening 17 therethrough. According to the figure 4 is in this preferred embodiment, the bearing shaft 16 is formed separately. A first part of the bearing axle 16 is mounted in the bearing opening 17 and a second part is connected here via a screw 35 to the first part. The valve body 9 is formed on the second part accordingly. The two-part design of the bearing shaft 16 has the advantage that on a shoulder 36 on the bearing axis 16, a seal 20 can be arranged. With the seal 20, the bearing opening 17 is substantially sealed so that no water can penetrate from the side of the drain pipe 3 through the bearing opening 17 to the outside. In other embodiments, the bearing shaft 16 may also be integrally formed.

Next, the valve body 9 according to the first embodiment relative to the bearing point 17 of the insert element at a bearing point 31, which is arranged on the drain pipe 3, stored. The bearing 31 here has the shape of a pin, which can engage in a frontally arranged on the bearing axis 16 opening 37. From the figure 4, which shows the explosive view, it can be well recognized that after Ilerstellung the screw 35, the insert member 13 can be inserted into the insert receptacle 14, in which case the opening 37 is moved in the direction of the pin 31 and receives it accordingly. From the figure 5 it will be seen then that the valve body 9 is mounted on the one hand in the bearing opening 17 and on the other hand with respect to the bearing opening 17 at the bearing point 31. The bearing point 31 and the bearing opening 17 are in the installed position on the geometric pivot axis A.

In the second embodiment according to FIGS. 11 to 13, the bearing axis is pivotably mounted in a bearing point 18 on the drainage pipe 3. The bearing 18 is provided by a bearing opening 18. The bearing axis 16 is thereby inserted through the bearing opening 18 in the drain pipe 3. During insertion, the bearing axis 16 comes with the valve flap 9 in connection. The bearing axis 16 is passed through an opening 38 on the valve flap.

In both embodiments, the actual valve flap 9 is connected to the bearing axis 16 via a crank region 2.

The bearing axis 16 has a free end 19 in both embodiments. The free End 19 is the end of a lever arm 21, which projects substantially at right angles from the bearing axis 16. The free end 19 and the lever arm 21 is arranged on the side of the insert element 13. The free end 19 is in communication with the said actuating element 15. By way of the actuating element 15, the bearing axis 16 can be pivoted correspondingly about the geometric pivot axis A. The free end 19 and the lever arm 21, lie outside the drain pipe 3. That is, the free end 19 of the lever arm 21 is actuated from outside the drain pipe 3. This has the advantage that the entire actuating mechanism is outside the water-bearing parts.

In both embodiments, a return element 22 is also arranged. The return element 22 acts on the valve body 9. In particular, the return element 22 acts on the valve body 9 in such a way that it is held in its closed position. Preferably, the return element 22, as shown by the figure 6, mounted on the insert element 13. In the first embodiment, the return element 22 is a leaf spring. In the second embodiment, the return element is also provided via a spring means, which is not shown in the figures. The return element 22 has the fundamental advantage that the valve body 9 is held in its closed position, which is particularly advantageous during assembly and disassembly. This prevents namely that the valve body 9 collides when inserting the insert element 13 into the insert receptacle 14 with the sealing surface 8, which could possibly lead to damage of the valve body 9.

In both embodiments, the insert element 13 has a circular-cylindrical bearing section 23. The insert receptacle 14 further has a circular cylindrical bearing receiving portion 24.

In the first embodiment, the orientation structure is a groove and comb connection, wherein on the insert member 13, a corresponding groove 38 is arranged, which takes a comb 39 on the insert receptacle 14 accordingly. The groove 38 can be seen in FIG. 9 and the comb 39 in FIG.

In both embodiments, the insert element 13 further comprises a securing element 27. With the securing element 27, after the insert element 13 has been inserted into the insert receptacle 14, the insert element 13 can be mechanically fixed to the drainage tube 3.

In the first embodiment, the securing element 27 is a cover 28 which is rotatably mounted on the insert element 13. The cover 28 has a thread 29. which cooperates with a correspondingly formed thread 30 on the drain pipe. By turning the lid 28, the thread 29 engages in the thread 30 and the cover 28 can be secured to the drain pipe 3 out. From the figure 5, the storage of the lid 28 is shown on the insert element 13 in more detail. The cover 28 has a groove 40, which is formed substantially around the central axis of the thread 29 circumferentially. In this groove 40 engages a circumferentially formed comb 41, which is arranged on the outside of the insert element 13, a. As a result, the cover 28 can be rotated about the central axis of the thread 29 without corresponding restriction, which then allows the corresponding engagement on the thread 30 and the corresponding tightening of the cover 28. When tightening the lid 28 due to the storage, the insert element 13 is not rotated in the insert. In the second embodiment, the securing element 27 is integrally formed on the insert element 13 and essentially has the shape of a bayonet closure. In this case, the securing element 27 engages the insert element 13 in a curved path 42, which is arranged in the region of the insert receptacle 14 on the side of the drain pipe 3, a.

The insert receptacle 14 according to the first embodiment opens into the drainage pipe 3 between the first branching point 11 and the second branching point 12. In this case, the insert receptacle 14 is oriented in such a way that the insert element 13 can be inserted into the insert receptacle in the direction of an insertion direction E extending transversely to the sealing surface 8. The insertion direction E is shown in Figures 2 and 3 with a corresponding arrow. The insertion direction E is substantially parallel to the geometric pivot axis A.

The concrete structure of the insert element 13 will now be shown with reference to FIGS. 4, 9 and 10. The insert element 13 has a bottom 42, from which a circumferential side wall 43 extends away. The side wall 43 provides the outer side of the bearing portion 23 and in the bottom 42, the bearing 47 is provided. Through soil
