Description

TECHNICAL AREA

The present invention relates to a washbasin according to the preamble of claim 1.

STATE OF THE ART

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

For example, the DE 10 2008 044 637 a washbasin which can be connected to a drain pipe. For this purpose, the washbasin has a chamber into which the water flows. The chamber is then followed by the drain pipe.

the DE 10 2008 044 637 has two major disadvantages. On the one hand, the shape of the washbasin with the chamber can only be produced with great effort. Various undercuts increase the manufacturing effort significantly, especially when manufacturing the ceramic washbasin. On the other hand, it is disadvantageous that the required installation space is comparatively large. This is due in particular to the arrangement of the drain pipe in the form of a pipe bend.

the DE 20 2008 008 557 U1 another vanity has become known, which has a connecting piece that connects to a drain section of the vanity and essentially protrudes to the rear.

Washstands with an overflow element are also known from the prior art. For example, the EP 1 754 838 a drain arrangement of a washbasin with an overflow element, which connects to the washbasin to the rear. Such overflow elements are typically behind a pretext arranged and very difficult to access in the installation position.

PRESENTATION OF THE INVENTION

Proceeding from this prior art, the invention is based on the object of specifying a washbasin arrangement which overcomes the disadvantages of the prior art. In particular, one object of the present invention is to specify a washstand arrangement with an overflow element, the washstand arrangement being designed to be more compact overall.

This object and other objects are solved by the subject matter of claim 1. Accordingly, a washbasin arrangement comprises a washbasin with a water basin, a cavity and a drain passage which extends from the water basin into the cavity, and a drain element arranged in the cavity for draining water from the drain passage and for feeding the water into a drain line. The washbasin has a rear wall, with which the washbasin can be brought into contact with a connection structure on the building side in the installed position, the cavity being open in the region of a rear wall of the washbasin, and the drain element having a wall structure which extends over the cross section of the drain passage extends. An overflow inlet opening is arranged on the wall structure. The overflow inlet opening is followed by an overflow channel with an overflow edge. Furthermore, a drain opening is arranged in the wall structure, which is connected to a drain channel that can be opened and closed with a check valve.

The arrangement of the drain element with the check valve and the overflow channel with the overflow edge in the cavity has the advantage that a very compact wash stand arrangement can be created. This is particularly so in comparison with the arrangements where the overflow unit is located behind a curtain. In addition, the ease of maintenance is increased.

This object and other objects are solved by the subject matter of claim 2. Accordingly, a washbasin arrangement comprises a washbasin with a water basin, a cavity and a drain passage which extends from the water basin into the cavity, and a drain element arranged in the cavity for draining water from the drain passage and for feeding the water into a drain line. The vanity also has a rear wall with which the vanity in the installed position a building-side connection structure can be brought into contact. The cavity is designed to be open in the area of a rear wall of the washbasin. The drain element has an overflow channel with an overflow edge, both the overflow channel and the overflow edge lying in said cavity.

The object according to claim 2 has the same advantages as the object according to claim 1.

Preferably, the outflow element according to claim 2 also has a wall structure which extends over the cross section of the outflow passage, with an overflow inlet opening being arranged in the wall structure, which is connected to the overflow channel with the overflow edge, and with a drain opening in the wall structure, which is a with a shut-off valve that can be opened and closed.

When the check valve is closed, the water in the water basin rises and flows into the overflow channel via the overflow inlet opening. The water then rises in the water basin and in the overflow channel. The overflow edge defines the maximum water level in the water basin. When the maximum water level is reached, the water then flows over the overflow edge. The height of the overflow edge defines the maximum storage height.

The following description of preferred features applies to both the subject-matter of claim 1 and the subject-matter of claim 2.

The overflow channel preferably extends upwards in the installed position in the cavity. The overflow channel is preferably located completely in the cavity.

The drainage passage from the water basin is preferably arranged on a side wall of the water basin and extends essentially backwards away from the water basin when viewed in the installed position. The drain passage preferably has a slight incline of at most 20° to the horizontal.

Preferably the check valve is in the cavity and/or in the drain passage.

The water basin is preferably delimited by an upper edge lying horizontally in the installed position. The edge spans a reference plane. The overflow edge is at a distance of 3 to 6 centimeters from the reference plane, seen at right angles to the reference plane.

Preferably, the entire drain element lies substantially entirely within the cavity. In particular, the drain element does not penetrate a plane which is spanned by said rear wall. Furthermore, the drain element does not protrude downwards from the cavity. If the drain element has a drain connector, this can be arranged in such a way that it protrudes out of the cavity as the only element of the drain element. The drain socket can protrude from the hollow space to the rear and/or downward out of the hollow space. Apart from the drain pipe, however, all other elements are preferably located inside the cavity.

The washbasin preferably also has a bottom wall, the bottom wall being designed to be open downwards in the region of the cavity in the installed position, and the drain element not projecting downwards beyond a plane spanned by the bottom wall. If the drain element has a drain connector, this can, as already mentioned, be arranged in such a way that it is the only element of the drain element that protrudes out of the cavity and, depending on the design, penetrates the plane spanned by the bottom wall.

Preferably, the overflow channel extends exclusively above said plane spanned by the bottom wall, as seen in the installed position.

The cavity is preferably delimited at the top by a wall area of the washbasin. The wall portion has an outer surface. Preferably, the spillway is no more than 3 to 6 centimeters from the outer surface. The wall area preferably has a through-opening for leading through a supply line to a water outlet fitting and/or for leading through a check valve actuating rod.

The cavity connects to the drain passage. In a preferred embodiment, the cavity has a first space section and a second space section. The first space section lies between the drain passage and the second space section. The bearing wall described herein preferably extends, viewed from the first space section, into the second space section. The overflow edge is preferably in the second space section. The second Viewed in the installed position, the space section extends upwards with respect to the first space section.

Said wall area extends with its surface essentially in said reference plane.

Preferably, the overflow channel and the drain channel flow into one another and continue as a common channel to a drain connection, the opening point of the overflow channel and the drain channel being in said cavity.

The drain connector is particularly preferably arranged in such a way that it does not penetrate through a plane spanned by the rear wall. In this variant, the drain connection is either completely in the cavity or protrudes downwards out of the cavity.

Preferably, the downcomer is the only element of the downcomer that protrudes from the cavity, with the exception of the downcomer, the downcomer lying entirely within the cavity.

The drain socket is used to connect to a waste water pipe. Preferably, the drain socket is arranged in the cavity.

The shut-off valve is preferably located in front of the drain opening or in the drain channel, viewed in the flow direction of the water.

Preferably, the drain opening comes to lie centrally in the wall structure as seen from the drain passage and with a lower edge at the level of or below a lower wall of the drain passage.

The overflow inlet opening is preferably located laterally next to the drain opening and comes to lie with a lower edge at the same level as or below a lower wall of the drain passage.

The wall structure is preferably shaped in such a way that the water to be drained does not accumulate in front of the wall structure, but is always fed to the drain opening.

Preferably, the overflow channel is surrounded by a wall on the side, with the Wall extending upwardly over the wall structure and a partition wall having the spill edge extending across the interior space defined by the wall.

The wall of the overflow channel preferably extends upwards away from the wall structure.

The overflow channel is preferably closed at the top with a cover, the inside of the cover being at a distance from the overflow edge.

The cover has the advantage that the wall can be shortened mechanically if necessary, and the overflow channel can then be closed with the cover. The drain element can thus be easily adapted to different types of washbasins.

In a preferred embodiment, two overflow inlet openings and two overflow channels are provided. Said drain opening with the drain channel is located between the two overflow inlet openings or overflow channels.

A bearing wall 30 preferably protrudes from the wall structure. The bearing wall protrudes into the cavity 4 of the vanity. The bearing wall 30 is designed to match the shape of the cavity 4 on the outside. The drainage passage for receiving the bearing wall preferably has a somewhat greater extent than in the section which directly adjoins the water basin.

The bearing wall is designed as a peripheral bearing wall and also serves to accommodate a sealing element that is also peripheral. The sealing element is arranged to cooperate with the walls of the cavity and/or with the rear wall.

The one sealing element is preferably a sealing element that is formed separately from the drain element. Alternatively, the at least one sealing element is integrally formed on the insert element.

The drain element can preferably be brought into connection with the washbasin by means of a cohesive adhesive connection and/or a mechanical connection. The mechanical connection is preferably a screw and dowel connection and/or a clamp connection between the drain element and the cavity.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figure 1 a vanity arrangement 1 according to the present invention is shown. The washbasin arrangement 1 comprises a washbasin 2 and a drain element 6.

The vanity 2 has a water basin 3 , a cavity 4 and a drain passage 5 . In the figure 1 the cavity 4 can only be partially seen behind the drain passage. In the cavity 4 is said drain element 6 for draining water arranged. The water can be fed to a drain line (not shown) via the drain element 6 . The drainage passage extends from the water basin 3 into the cavity 4 in such a way that water can be guided from the water basin into the cavity 4 or to the drainage element 6 .

The water basin 3 is delimited at the top by an upper edge 15 . In the installed position, the upper edge 15 lies in the horizontal line H. In installed position means in the installed and ready-to-use state. In the rear area, the washbasin also has a wall area 17 . The wall area 17 delimits the cavity 4 at the top. The wall area has an outer surface 18 at the top, which preferably also lies in said reference plane B. In the embodiment shown, the wall area 17 has a through-opening 19 . The through opening 19 opens into the cavity 4 and serves to feed through a supply line to a water outlet fitting and/or to feed through a check valve actuating rod.

In the figure 2 the vanity assembly 1 is shown from behind. The vanity 2 has a rear wall 7 at the rear. In the installed position, the wash stand 2 can be brought into contact with a connection structure on the building side with the rear wall 7 . The washbasin 2 also has a bottom wall 16 .

Like from the Figures 2 to 4 As can be seen, the cavity 4 is accessible via the rear wall 7 and the bottom wall 16 . The cavity 4 is designed to be open in the area of the rear wall 7 . The cavity 4 in the area of the bottom wall 16 is also designed to be open.

With regard to the cavity, the drain element 6 is arranged substantially entirely in said cavity 4. This means that the drain element 6 projects out of the cavity 4 neither beyond a plane spanned by the rear wall 7 nor beyond a plane spanned by the bottom wall 16 . This apart from a drain pipe or drain connector 21, through which the water is fed to a sewage pipe. Here the drain pipe 21 protrudes downwards out of the cavity 4 . Furthermore, the drain element 6 partially extends into the drain passage 5 .

The flow element 2 has in the embodiment shown, as in the Figures 2 to 6 shown, a wall structure 8 which extends completely over the cross section of the drain passage 5 in the state connected to the washstand 2 . In the embodiment shown, the drain element 2 has two fastening openings 31, with which the drain element 2 can be connected to the washbasin.

The drain element 2 also has a drain channel 14 and an overflow channel 10 . The drain channel 14 and the overflow channel 10 are formed on the wall structure 8 here. Preferably, the drain element 2 is molded from plastic.

A drainage opening 12 is arranged in the wall structure 8 . The drain opening 12 is followed by the drain channel 14 . The figures show an embodiment in which a check valve 13 is located in front of the outflow channel 14 and closes the outflow opening 12 . The check valve 13 here has the shape of a valve flap. The shut-off valve 13 can, however, be designed in a different way and, for example, be located in the outflow channel 14 . Regardless of the design or position of the check valve 13, the check valve 13 is used to seal the drain opening 12 or the drain channel 14 tightly. When the check valve 13 is open, the water flows into the drain channel 14 .

The overflow channel 10 is used to drain water from the water basin 3 when a certain backwater level is reached with the check valve closed. For this purpose, the overflow channel 10 has an overflow edge 11 . The position of the overflow edge 11 defines the maximum water level in the water basin 3. The overflow channel 10 and the overflow edge 11 are also in the cavity 4 in the embodiment shown. An overflow inlet opening 11 is arranged in the wall structure 8, which is then connected to the overflow channel 10. The overflow channel 10 then extends upwards to the overflow edge 11 and then from the overflow edge 11 downwards again.

In the embodiment shown, the overflow inlet opening 11 and the drain opening 12 are arranged as separate openings. Viewed from the water basin 3 or from the outflow passage 5 , the overflow channel 10 is accessible via the overflow inlet opening 9 and the outflow channel 14 is accessible via an outflow opening 12 . The overflow inlet opening 9 and the outlet opening 12 are arranged side by side offset from one another. This means that the overflow inlet opening 9 and the outlet opening 12 are at a distance from one another.

The overflow channel 10 and the outlet channel 14 flow into one another at an outlet point 36 and continue after the outlet point 36 as a common channel 20 to an outlet port 21 . The mouth of the overflow channel 10 and from Outflow channel 14 is also located in said cavity 4. Outflow connection piece 21 can then be followed by a drain pipe. The outlet point 36 is located behind the overflow edge 11 and behind the check valve 13, viewed in the flow direction from the overflow inlet opening 9 and the outlet opening 12.

The drain opening 12 and overflow inlet opening 11 are located in such a way that they are in the clear width of the drain passage 5 in the installed position. This means that the water can flow unhindered from the drain passage 5 to the drain opening 12 and the overflow inlet opening 11 . The drain opening 12 is seen from the drain passage 5 in the center of the wall structure 8 and has a lower edge 22 at the level of or below a lower wall 23 of the drain passage 5. The overflow inlet opening 9 is also located laterally next to the drain opening 12 and has a lower edge 24 to be level with or below a lower wall 23 of the drain passage 5.

The overflow channel 10 is, as in the Figures 5 and 6 is well shown surrounded by a wall 25 laterally. The wall 25 extends above the wall structure 8 upwards. A partition wall 26 extends transversely through the interior space 27 delimited by the wall 25. The partition wall 26 has the overflow edge 11 mentioned. The overflow channel 10 is closed with a cover 28 at the top. The inside 29 of the lid is at a distance from the overflow edge 11.

A bearing wall 30 protrudes from the wall structure 8 . The bearing wall 30 protrudes into the cavity 4 of the vanity. The bearing wall 30 is designed on the outside to match the shape of a first spatial section of the cavity 4 . The first room section follows the drain passage 5 . The first space section for accommodating the bearing wall 30 preferably has a somewhat greater extent than the extent of the drain passage 5 , which directly adjoins the water basin 3 . The remaining part of the drain element 6 lies in a second spatial area of the cavity, with the second spatial area adjoining the first spatial area.

The bearing wall 30 is designed as a peripheral bearing wall and is also used to accommodate a sealing element 32 that is also peripheral. The sealing element 32 is arranged to interact with the walls of the cavity 4 .

In the figure 7 a sectional view through the drain channel is shown. the figure 8 then shows a sectional view through the overflow channel. The overflow edge is, as in the figure 8 shown at a distance of 3 to 6 centimeters from the reference plane B. The distance is marked A.

the Figures 9 and 10 then show a front view of the drain element 6 and a sectional view. From the sectional view taken along section line XX in figure 9 it can be seen that the overflow channel 10 extends from the overflow inlet opening 9 with a first channel section 37 . The first channel section 37 is followed by a riser section 38 . The riser section 38 leads to the overflow edge 11. After the overflow edge 11, the riser section 38 is followed by a fall section 39. The fall section 39 then opens into the discharge channel 14 at the opening 36. The riser section 38 and the fall section 39 run parallel to one another here and, as already mentioned, are separated from one another by the partition wall 26.

Of the figure 10 It is further apparent that in the embodiment shown, the outflow channel 12 has a deflection section 40 which deflects the outflow channel in the direction of the overflow channel 20 . This deflection section 40 allows the opening point 36 to be placed behind a closed wall section of the wall structure 8 .
