Description

TITLE

BASIN

TECHNICAL AREA

The present invention relates to a washbasin according to the preamble of claim

STATE OF THE ART

Washbasin systems with corresponding sequences for the water have become known from the prior art.

For example, DE 10 2008 044 637 discloses a wash basin which can be connected to a drain pipe. For this purpose, the washbasin has a chamber into which the water flows. The chamber then joins the drainpipe.

DE 10 2008 044 637 has two major disadvantages. On the one hand, the shape of the washstand with the chamber is very expensive to produce. Various undercuts significantly increase the Flerstellaufwand, especially in the production of ceramic washbasin. On the other hand, it is disadvantageous that the required installation space is comparatively large. This in particular due to the arrangement of the drainage pipe in the form of a pipe bend.

DE 20 2008 008 557 U1 has disclosed another washbasin which has a connecting piece which adjoins an outflow section of the washbasin and projects substantially rearward.

PRESENTATION OF THE INVENTION

Based on this prior art, the present invention has the object to provide a vanity, which overcomes the disadvantages of the prior art. A particularly preferred object is to provide a washstand, which is easier to produce.

This object is solved by the subject matter of claim 1. Accordingly, a washstand assembly comprises a wash basin with a water basin and a drain opening through which water to be discharged from the water basin can be led away, wherein the drain opening opens into an interior, which seen in the direction of water preferably has a larger cross section than the drain opening, wherein the wash basin a Has rear wall, with which the washstand in installation position comes into contact with a building-side connection structure, and wherein in the region of a rear wall of the washstand, the interior is open. The connection structure is typically a wall in a bathroom or a mounting frame with a panel. Furthermore, the washbasin arrangement comprises an insert element with an outlet connection for connection to a building-side sewer line, wherein the insert element communicates with the wash basin in such a way that the interior is tightly sealed with respect to water and that the water from the drain opening can be fed to the outlet connection. In other words, the insert element serves as an element for carrying away the water, which flows from the drain opening in the direction of the interior.

Due to the closure with the insert element, the shape of the washbasin in the region of the insert or of the inner space, that is to say in the direction of flow after the discharge opening, can be improved with regard to production-technical aspects. In particular, the arrangement of the insert element allows the omission of complex and difficult to shape undercuts. Accordingly, eliminates a complex shaping and demolding of the washstand as this is known for example from the prior art.

The insert element is designed as a separate part of the washstand and can, as mentioned, be connected to the washstand.

Preferably, the vanity is made of ceramic and the insert is made of plastic manufactured.

Preferably, the discharge nozzle protrudes from the rear wall of the wash basin to the rear away. Preferably, the discharge nozzle extends from the rear wall, in particular with a maximum angle of 10 ° in the installation position downwards, ie away from a horizontal plane.

Particularly preferably, the discharge nozzle is arranged such that the discharge nozzle does not intersect a reference plane extending at right angles to the rear wall and extending through a lowermost edge of the rear wall. This means that the drain neck does not protrude out of a virtual border, which defines itself from the side edges of the rear wall and extends at right angles to the rear wall. As a result, the compactness of the washbasin arrangement can be increased. In addition, the area below the washstand is not blocked by the drain neck, which is advantageous for the arrangement of a bathroom furniture.

The insert element preferably has a flange region, from which a wall projecting into the interior space protrudes. The wall is formed on the outside substantially matching the shape of the interior. The wall provides a drainage space or limits the drainage space, which drainage space is located substantially in the interior. Through the drainage chamber, the water can be led away from the drain opening.

By the expression appropriate to the shape is understood that the wall and the interior are formed to each other such that the wall can be inserted without colliding with the interior in the latter. Preferably there is clearance between the wall and the interior. In particular, in the said play, a sealing element, as described below, is arranged.

The discharge nozzle preferably protrudes from the discharge space and penetrates the flange region in the cross section of the flange region. The drain connection closes to the drainage room. Preferably, the drain pipe is seen in installation position at the lowest point of the discharge space. This ensures that no residual water remains in the drainage room.

Preferably, the flange portion surrounds the outside of the wall completely. This increases the stability of the insert element. Attachment points for fastening the insert element to the wash basin are preferably arranged on the flange area. Preferably, the rear wall has a recess in which the flange area comes to rest. Particularly preferably, the depression is sufficiently deep, so that the flange region does not project beyond the rear wall.

Preferably, the wall is at least partially formed as a double wall with two mutually spaced wall sections. The double wall preferably provides a stiffening, such that the wall is clamped in the assembled state in the interior due to the stiffening.

Preferably, the insert element has at least one sealing surface on which at least one sealing element is arranged for cooperation with the walls of the interior and / or with the rear wall. The sealing surface essentially serves as a bearing surface or as a mounting surface for a sealing element.

Preferably, the at least one sealing element is a sealing element formed separately from the insert element. This means that the sealing element can be connected to the insert element. Alternatively, the at least one sealing element is integrally formed on the insert element; for example via an injection molding process.

Preferably, the sealing surface is provided by the said wall, wherein the sealing element is arranged at least in the region of an end face of the wall, wherein the sealing element has a front-side sealing lip, which substantially surrounds the drain opening on the side of the interior; and / or wherein the sealing element is arranged in the region of an outer side of the wall, and surrounds the wall completely circumferentially with at least one circumferential sealing lip. Alternatively or additionally, the sealing surface is provided by said flange portion. This means that the at least one sealing element comes to lie between the flange area and the rear wall and / or recess of the rear wall.

The combined provision of the sealing surface on the wall and on the flange region has the advantage that the sealing element coming from the wall can be pulled up into the flange region. As a result, multiple sealing lines can be provided.

Preferably, the insert element via a cohesive adhesive bond and / or a mechanical connection with the washstand can be brought into connection, wherein the mechanical connection is preferably a screw and dowel connection; and / or wherein the mechanical connection is preferably a clamping connection between the insert element and the interior.

The adhesive bond has the advantage that it can serve as a sealing element depending on the training. The mechanical connection has the advantage that it is typically solvable, whereby the insert element is exchangeable during maintenance. The combined connection combines the two advantages.

Preferably, the discharge nozzle is arranged laterally offset from the discharge opening, in particular such that the discharge nozzle is outside a range which is formed by the inside width of the boundary walls of the discharge opening with a view towards the interior. The drain pipe is thus arranged in particular such that it is not visible when considered from the front of the washbasin by a side wall which limits the sink.

Preferably, the drain opening penetrates a side wall of the water basin, the drain opening extending away from a bottom area of the washbasin in the direction of said side wall away, and / or wherein the drain opening is arranged centrally in the side wall with respect to a transverse direction of the water basin. The discharge nozzle is in the central arrangement then laterally offset from said central arrangement. Preferably, the insert element and / or the rear wall of the washstand has at least one coding element, which is designed such that a false appearance of the insert element can be prevented. In particular, it is prevented that the discharge nozzle is located on the insert element in the wrong place.

The coding element is preferably provided by the depression on the rear wall of the washstand and the flange region of the insert element and by the wall arranged offset relative to the flange region or by the interior which is offset to the recess. Flierdurch can be created by the shape of a simple coding element.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figure 1, a washstand assembly 1 is shown. The washstand arrangement 1 essentially comprises a washstand 2 and an insert element 7, which can be connected to the washstand 2 in the region of the drain. The washstand 2 comprises a water basin 3 and a drain opening 4, through which water to be discharged from the water basin 3 can be led away. The water basin 3 is limited in the embodiment shown by a side wall 23 and a bottom portion 24. The side wall 23 in this embodiment extends completely around the bottom region 24. Other embodiments are also conceivable. In the embodiment shown, the drain opening lies in a rear side wall 23 and directly adjoins the floor area 24. The side wall 24 adjoins an optional vanity surface 26 on the upper side.

In the figure 2, the washstand assembly 1 is shown from the rear. The washstand further comprises a rear wall 6, which may rest against a connection structure. The connection structure is for example a wall or a mounting frame or another similar structure. Next, the washstand 2 in the back wall 6 mounting holes 27. About this attachment opening 27 of the washbasin 2 can be firmly connected to the connection structure.

From the figure 2 can be well recognized that the insert element 7 is arranged in the region of the rear wall 6. The insert element 7 comprises a drain neck 8 for connection to a building-side sewer pipe, which is not shown in the figures. The insert element 7 is preferably made of plastic and the washstand 2 is preferably made of ceramic.

FIG. 3 shows a sectional perspective view of the washbasin arrangement 1. The drain opening 4 of the water basin 3 opens into an interior 5, which is also part of the vanity 1 and which is behind the side wall 23. The water flows along a flow direction F through the opening 4 into the interior 5. The interior 5 preferably has a larger cross-section than the drain opening 4. That is, the interior 5 expands after the drain opening 4 accordingly. In the area of the rear wall 6, the interior 5 is open. That is, the interior 5 is accessible from behind over the rear wall 6 ago. The insert element 7 stands in such a way with the washstand 2 in connection that the inner space 5 is sealed with respect to water. That is, with the insert element 7 is the washbasin 2 a kind Water tank created, which receives the water flowing through the drain opening 4 and the drain pipe 8 supplies. The arrangement of the insert element 7, which closes the inner space 5, has the advantage that the inner space 5 can be well formed. The interior 5 may be formed in particular without undercuts. Such undercuts would be necessary to drain the water accordingly. In the present case, essentially the insert element 7 serves to discharge the water accordingly. This means that preferably all structures with respect to the water flow to the drain opening 4, that is to say in the interior 5, are predetermined by the insert element 7.

The drain pipe 8 protrudes from the rear wall 6 of the washbasin 2 to the rear away. This can be well recognized by the figures 3 and 4. In this case, the discharge nozzle protrudes in particular from the rear wall 6 of the washbasin 2 in such a way that it does not intersect a reference plane R extending at right angles to the rear wall 6 and extending through the lower edge 9 of the rear wall 6. The reference plane R is shown in FIG. In other words, that means that the outlet pipe 8 extends substantially horizontally or at a slight angle to the horizontal of the rear wall 6. This design has the advantage that the sewer line does not come to lie below the washstand 2 on the wall side. That is, the area B below the reference plane R or generally below the washstand 2 is not affected by the drain pipe 8 or connected thereto elements such as a siphon, etc. Such elements would then be arranged in the connection structure or the wall. The user can here have the full volume below the washbasin for example, a bathroom furniture.

With reference to Figures 3 to 5, various features of the insert element 7 will now be explained in more detail. The insert element 7 has a flange region 10, from which a wall 11 protruding into the interior 5 is located. The wall 1 1 is on the outside suitably formed to the shape of the interior 5, so that the wall 1 1 can be inserted into the interior 5. The wall 1 1 defines a discharge space 12, which is then also substantially in the interior 5. The outflow chamber 12 lies in such a way to the drainage opening 4 that the water flowing through the drainage opening 4 can flow into the drainage space 12. Of the Outlet nozzle 8 protrudes from the discharge space 12 away, as shown in the two sectional views. That is, the water will flow away via the outlet pipe 8 from the drainage chamber 12. In this case, the discharge nozzle 8 substantially penetrates the flange region 10.

The flange region 10 has mechanical reinforcing structures 28, which are formed here by way of example honeycomb. These mechanical reinforcing structures increase the rigidity of the flange portion 10.

The outlet pipe 8 is located in the installed position at the lowest point of the discharge space 12. This ensures that the entire amount of water that is supplied to the discharge space can flow out of the discharge space 12. Preferably, the lower portion 29 of the discharge chamber 12 seen to the horizontal, a slight angled inclination, so that the water can be well supplied to the drain port 8 via this fluidic optimization.

The flange 10 surrounds the wall 1 1 on the outside substantially completely. In other words, the wall 11 essentially projects away from the flange area 10. The rear wall 6 has a recess 16 in which the flange portion 10 comes to rest. That is, the insert element 7 is arranged on the rear wall 6, that this, apart from the discharge nozzle 8, does not extend beyond the rear wall 6, but is recessed with respect to the rear wall 6 in the washbasin 3. At least in sections, the wall 11 is at least partially formed as a double wall with two mutually spaced wall portions 14. This is shown correspondingly in FIGS. 3 and 4. During assembly, the two mutually spaced wall sections 14 are slightly deformed to each other, so that the double wall provides a spring action. The spring effect is such that the wall 11 is slightly clamped in the assembled state in the interior 5 due to the spring action.

Furthermore, the insert element 7 has at least one sealing surface 15. On the sealing surface 15, a sealing element 17 for cooperation with the walls of the inner space 5 and / or with the rear wall 6 is arranged. In the embodiment shown, the Sealing surface 15 disposed on the outside of the wall 11 and extends slightly into the flange portion 1 1 inside. There are different sealing lips 19, 21 and 31 arranged.

A first sealing lip 19 is positioned on the end face 18 of the wall 1 1 and extends in the direction of the drain opening 4. With the sealing lip 19 is a gap between the end face 18 of the insert member 7 and an orifice surface 30, which the drain opening 4 on the side of the interior 5 outlined, provided.

In the embodiment shown, further sealing lips 21 are arranged. Here, three sealing lips 21 are arranged, which can be referred to as circumferential sealing lips 21. These circumferential sealing lips 21 extend completely circumferentially on the outer side 20 of the wall 1 1 around the discharge space 12 around. In this case, the circumferential sealing lips 21 cooperate with the corresponding wall of the inner space 5. It is also possible to arrange more or fewer than three sealing lips 21. If the wall 11 is partially formed as a double wall, the double wall has the additional effect that a force is exerted on the circumferential sealing lips 21, so that they are constantly pressed against the interior 5.

Another sealing lip 31 is arranged here in the region of the flange region 10. In this case, the further sealing lip 31 is directed against the surface of the recess 16.

In other embodiments, it would also be possible to omit at least one of the sealing lips 19, 21 or 31.

In the illustrated embodiment, the sealing member 17 is provided as a sealing member formed separately from the insert member 7. Alternatively, however, the sealing element 17 may also be formed integrally on the insert element 7, for example via an injection molding process. The separate embodiment of the sealing element from the insert element 7 is shown correspondingly in FIG. 5, here the sealing element 7 is shown at a distance from the insert element 7.

As can be well recognized by all figures, the drain pipe 8 is offset laterally arranged to the drain opening 4. The discharge nozzle 8 is in particular arranged such that the discharge nozzle 8 is outside of an area which is formed by the clear width of the boundary walls 22 of the drain opening 4 with a view towards the interior 5. When viewed from the front in the position of use, this means that the discharge nozzle 8 is essentially not visible. If the drainage opening 4 is arranged centrally in the side wall 23 with respect to a transverse direction Q of the water basin 3, the lateral displacement of the drainage nozzle 8 to the drainage opening 4 has the further advantage that the drainage nozzle 8 is arranged laterally offset from the wash basin 2 as a whole. As a result, a free region Z is created, which is shown in FIG. Through this free area Z, water pipes can be led to the outlet fittings arranged on the washstand or in the connection structure.

Furthermore, the insert element 8 or the rear wall 6 of the washstand 2 has at least one coding element 25. The coding element 25 is designed in such a way that a false build of the insert element 7 can be prevented. The coding element 25 can have various shapes. In the embodiment shown, the coding element 25 is provided essentially by the depression 16 on the rear wall of the washstand 2 and the flange region 10 of the insert element 7. From the figure 5 can be well recognized that the wall 1 1 is arranged laterally offset relative to the flange portion 10. Likewise, the interior 5 is also arranged laterally offset with respect to the recess 16. This can prevent that the insert element 7 can be installed incorrectly. The insert element 7 is preferably connected to the washstand 2 via a mechanical connection and / or a cohesive connection. In the embodiment shown, a mechanical connection is shown. For this purpose, the flange portion 10 mounting holes 27 through which screws 32 could be performed. The screws 32 preferably engage in dowels, which are in communication with the washstand 2. The dowels are not shown in the figures.

In the case of a cohesive connection, it would be conceivable for a zone for an adhesive layer to be arranged on the flange region 10. In this case, the insert element 7 is then glued, for example, to the recess 16. Such an adhesive layer could also act as a sealing layer at the same time. LIST OF REFERENCE NUMBERS
