Description

Washstand device

Technical Field

The invention relates to a washstand in accordance with the preamble of claim 1.

Background

Vanity systems with corresponding water discharge devices are known from the prior art.

DE102008044637, for example, discloses a wash stand which can be connected to an exhaust pipe. For this purpose, the washstand has a chamber into which water flows. The discharge tube then adjoins the chamber.

DE102008044637 has two main disadvantages. On the one hand, the shaping of the washstand with the chamber can only be produced in a very cost-effective manner. In particular, when ceramic washstands are produced from ceramic, the various undercuts significantly increase the production effort. On the other hand, disadvantageously: the required installation space is relatively large. This is particularly because the discharge pipe is provided in the form of an elbow.

Another washstand is known from DE202008008557U1, which has a connecting piece which adjoins the discharge section of the washstand and projects substantially rearwards.

Furthermore, wash stands with overflow elements are known from the prior art. For example, EP1754838 discloses a discharge device for a wash stand with an overflow element which adjoins the wash stand to the rear. Such overflow elements are typically arranged behind the front wall and are difficult to access in the installed position.

Disclosure of Invention

Starting from this prior art, the invention is based on the object of: a vanity apparatus is specified which overcomes the disadvantages of the prior art. In particular, it is an object of the invention to specify a washstand arrangement with a drainage element which is not susceptible to clogging in the region of the shut-off valve.

This and other objects are achieved by the subject matter of claim 1. Accordingly, a vanity apparatus includes: a vanity having a basin, a cavity, and a drain passage extending from the basin into the cavity; and a drain element at least partially disposed in the cavity for directing water away from the drain passage and for delivering water into the drain line. The discharge element has an overflow channel with an overflow edge and a discharge channel with a shut-off valve. Viewed from the basin, can enter the overflow channel via the overflow entrance opening and can enter the discharge channel via the discharge opening. The overflow inlet opening and the discharge opening are arranged adjacent to one another laterally offset.

Thus, water flowing through the discharge passage strikes the discharge opening and overflows into the opening. The advantage of the spaced apart arrangement is that: the two functions of "drain" and "overflow" are formed at different channels so as to be separated from each other. During operation, it also happens that: the discharge opening and/or discharge passage is damaged or even blocked by hair and other objects. By separating from the discharge channel it is ensured that: in the event of a blockage of the discharge channel, the water can be reliably conducted away from the basin via the overflow channel.

The discharge opening and the overflow opening are spaced apart from each other by a distance. The overflow opening and the discharge opening are two openings which are different and which are arranged separately from each other.

With the shut-off valve closed, the water in the basin rises and flows via the overflow inlet opening into the overflow channel. The water then rises in the basin and in the overflow channel. The overflow edge defines the maximum accumulation height in the basin. When the maximum accumulation height is reached, the water then flows out via the overflow edge. The height of the overflow edge defines the maximum accumulation height.

Preferably, the lower edge of the discharge opening is lower than the lower edge of the overflow inlet opening, viewed in the loading position. Thereby it is ensured that: when the drain channel is open, water can always flow out of the basin via the drain channel.

Preferably, the overflow inlet opening and/or the discharge opening extends substantially at least over the entire clear height of the discharge channel. Thereby, the cross section of each opening can be maximized.

Preferably, the overflow channel and the discharge channel extend as separate channels after the overflow inlet opening or the discharge opening and, viewed in the flow direction, only open into one another at the opening point after the overflow edge.

Preferably, the overflow channel and the discharge channel continue as a common channel after the opening point towards the discharge connection. For example, a drain can be connected at a drain fitting.

Preferably, the points of entry of the overflow channel and the discharge channel are located in the cavity of the washstand.

Preferably, the overflow channel extends with a first channel section from the overflow inlet opening, wherein an ascending section leading to the overflow edge adjoins the first channel section, wherein a descending section adjoins the ascending section after the overflow edge, the descending section preferably extending parallel to the ascending section, wherein the descending section opens into the discharge channel.

Preferably, the first channel section extends rearward in the direction of the discharge passage, viewed in the installed position. The rising and falling sections extend substantially in a vertical direction or at a small angle to the vertical direction, upwards or downwards.

In one embodiment variant, the passage of the descending section into the discharge channel is a direct passage. This means that: the descending section merges directly into the discharge channel. In an alternative embodiment variant, the introduction is an indirect introduction. In this case, a further channel section adjoins the drop section, which then opens into the discharge channel.

Preferably, the rising section and the falling section are separated from each other by a partition wall, wherein an upper end of the partition wall provides the overflow edge.

Preferably, the partition wall has an arcuate cross section, as viewed from above, wherein the partition wall has at least one convexly rounded section and/or at least one concavely rounded section. The following advantages are obtained by the arc-shaped arrangement: the overflow channel can be arranged in a manner as space-saving as possible. Furthermore, the overflow cross section can be increased.

Preferably, the point of entry of the overflow channel and the discharge channel is located between the overflow entry opening and the discharge opening. This is especially observed through the discharge passage. In the loading position, the access point is located behind the discharge passage.

Preferably, the discharge channel has a deflection section, viewed in the water flow direction, after the discharge opening, which deflects the discharge channel in the direction of the overflow channel. The deflecting section can here follow the discharge opening directly or at a distance from the discharge opening.

Preferably, the discharge element has a wall structure extending over the discharge passage cross section, wherein the overflow inlet opening and the discharge opening are provided in the wall structure.

Preferably, the drain channel and the overflow channel are rearwardly adjacent to the wall structure.

Further preferred and further optional features of the washstand arrangement are described below:

preferably, the basin has a rear wall with which the basin can be brought into contact with the building-side connection in the installed position, wherein the cavity is formed in an open manner in the region of the rear wall of the basin. Preferably, the discharge element with the shut-off valve and the overflow channel with the overflow edge are located substantially in the cavity. The advantages obtained by providing the discharge element with the shut-off valve and the overflow channel with the overflow edge in the cavity are: a very compact washstand arrangement can be realized. This is particularly true in comparison to an arrangement in which the overflow unit is behind the front wall. In addition, maintenance convenience is improved.

Preferably, the wall structure extends over and accordingly closes the cross section of the drain passage, so that water can flow out of the drain passage only via the drain opening and the overflow inlet opening. The discharge opening and the overflow inlet opening are here at least in the clear width of the discharge channel.

In another variant, the overflow channel and the overflow edge are located substantially in the cavity.

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

Preferably, the entire discharge element is located substantially entirely within the cavity. In particular, the discharge element does not penetrate the plane spanned by said rear wall. Furthermore, the drainage element does not protrude downwardly from the cavity. If the discharge element has a discharge nipple, it can be arranged such that it projects outwards from the cavity as the only element of the discharge element. In this case, the outlet nipple can project from the cavity toward the rear and/or downward. However, all other elements than the drain fitting are preferably located in the interior of the cavity.

Preferably, the washstand also has a bottom wall, wherein the bottom wall is formed in a downwardly open manner in the region of the cavity in the built-in position, and wherein the drainage element does not project downwards beyond the plane spanned by the bottom wall. If the discharge element has a discharge nipple, as already mentioned, this can be arranged such that it projects outwardly from the cavity as the only element of the discharge element and, here, penetrates the plane spanned by the bottom wall according to design.

Preferably, the overflow channel extends only above said plane spanned by the bottom wall, viewed in the loading position.

Preferably, the cavity is defined upwardly by a wall area of the vanity. The wall region has an outer surface. Preferably, the overflow edge is at most 3 to 6 cm from the outer surface. Preferably, the wall region has a through-opening for passing the inlet line to the water outlet fitting and/or for passing the shut-off valve operating lever.

Detailed Description

Fig. 1 shows a washstand arrangement 1 according to the invention. The washstand apparatus 1 includes a washstand 2 and a discharge member 6.

The washstand 2 has a basin 3, a cavity 4 and a discharge passage 5. In fig. 1, the cavity 4 is only partially visible behind the vent passage. Said discharge element 6 for leading away water is arranged in the cavity 4. Water can be fed to a discharge line (not shown) via the discharge element 6. A drain passage extends from the basin 3 into the cavity 4 so that water can be directed from the basin into the cavity 4 or to the drain element 6.

The basin 3 is delimited on the upper side by an upper edge 15. In the installed position, the upper edge 15 is located in the horizontal direction H. In the loading position means: in the ready-to-use and loaded state. In the rear area, the washstand also has a wall area 17. The wall area 17 delimits the cavity 4 upwards. The wall region has an outer surface 18 at the upper part, which preferably also lies in the reference plane B. In the embodiment shown, the wall region 17 has a through opening 19. The through-opening 19 opens into the cavity 4 and serves for the passage of an inlet line to the water outlet fitting and/or for the passage of a stop valve actuating lever.

Fig. 2 shows the washstand arrangement 1 from the rear. The washstand 2 has a rear wall 7 at the rear. In the installed position, the washstand 2 can be brought into contact with the building-side connection by means of the rear wall 7. The washstand 2 also has a bottom wall 16.

As can be seen from fig. 2 to 4, the cavity 4 can be accessed via the rear wall 7 and the bottom wall 16. The cavity 4 is formed in an open manner in the region of the rear wall 7. The cavity 4 is likewise formed in an open manner in the region of the bottom wall 16.

With respect to the cavity, the discharge element 6 is substantially completely arranged in said cavity 4. This means that: the discharge element 6 does not protrude from the cavity 4 beyond the plane spanned by the rear wall 7 nor beyond the plane spanned by the bottom wall 16. This is the delivery of water to the drain pipe via the drain pipe or fitting without regard to the drain pipe or fitting. Here, a discharge nipple 21 projects downwards from the cavity 4. Furthermore, the discharge element 6 extends partially into the discharge passage 5.

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

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

A discharge opening 12 is provided in the wall structure 8. The discharge channel 14 is adjacent to the discharge opening 12. In the figures an embodiment is shown in which a shut-off valve 13 is located in front of the discharge channel 14 and closes the discharge opening 12. The shut-off valve 13 has the shape of a flap. However, the shut-off valve 13 can be formed in other ways and, for example, be located in the discharge channel 14. The shut-off valve 13 serves to sealingly close the discharge opening 12 or the discharge channel 14, irrespective of the design or position of the shut-off valve 13. With the shut-off valve 13 closed, water accumulates in the basin 3. With the shut-off valve 13 open, water flows out into the discharge channel 14.

The overflow channel 10 serves to drain water out of the basin 3 when a certain accumulation height is reached with the shut-off valve closed. For this purpose, the overflow channel 10 has an overflow edge 11. The position of the overflow edge 11 defines the highest accumulation height in the basin 3. The overflow channel 10 and the overflow edge 11 are likewise located in the cavity 4 in the embodiment shown. An overflow inlet opening 11 is provided in the wall structure 8, to which overflow channel 10 then adjoins. Subsequently, the overflow channel 10 extends up to the overflow edge 11 and then continues from the overflow edge 11 downwards.

In the embodiment shown, the overflow inlet opening 11 and the discharge opening 12 are provided as separate openings. Here, the overflow channel 10 can be entered via the overflow inlet opening 9 and the discharge channel 14 can be entered via the discharge opening 12, as seen from the basin 3 or the discharge channel 5. The overflow inlet opening 9 and the discharge opening 12 are arranged laterally offset from one another and adjacent to one another. This means that the overflow inlet opening 9 and the discharge opening 12 are at a distance from each other.

The overflow channel 10 and the discharge channel 14 open into one another at the opening point 36 and continue after the opening point 36 as a common channel 20 toward the discharge pipe connection 21. The points of entry of the overflow channel 10 and the discharge channel 14 are likewise located in the cavity 4. Then, the discharge pipe can be connected to the discharge pipe joint 21. The opening 36 is located behind the overflow edge 11 and behind the shut-off valve 13, as seen in the flow direction from the overflow inlet opening 9 and the discharge opening 12.

The discharge opening 12 and the overflow inlet opening 11 are positioned such that they are located in the installation position in the net width of the discharge channel 5. This means that water can flow unimpeded from the discharge passage 5 to the discharge opening 12 and overflow into the opening 11. The discharge opening 12 is centrally located in the wall structure 8, as seen from the discharge passage 5, and the lower edge 22 is located at or below the level of the lower wall portion 23 of the discharge passage 5. Furthermore, the overflow inlet opening 9 is located laterally beside the discharge opening 12 and the lower edge 24 is located at or below the level of the lower wall portion 23 of the discharge channel 5.

As is well shown in fig. 5 and 6, the overflow channel 10 is laterally surrounded by a wall 25. The wall portion 25 extends up above the wall structure 8. The partition wall 26 extends transversely across an interior space 27 bounded by the wall portion 25. The partition wall 26 has said overflow edge 11. The overflow channel 10 is closed upwards by means of a cover 28. The inner side 29 of the cover is here at a distance from the overflow edge 11.

The support wall portions 30 protrude from the wall structure 8. The support wall 30 projects into the cavity 4 of the washstand. The support wall 30 is formed on the outside in a manner adapted to the shape of the first space section of the cavity 4. The first space section adjoins the discharge passage 5. Preferably, the range of the first space section for accommodating the support wall portion 30 is slightly larger than the range of the discharge passage 5 directly adjacent to the tub 3. The remaining part of the discharge element 6 is located in a second spatial region of the cavity, wherein the second spatial region adjoins the first spatial region.

The support wall 30 is formed as a circumferential support wall and also serves to accommodate a likewise circumferential sealing element 32. The sealing element 32 is arranged to co-act with the wall of the cavity 4.

A cross-sectional view through the vent passage is shown in fig. 7. Fig. 8 then shows a sectional view through the overflow channel. As shown in fig. 8, the overflow edge is at a distance of 3 to 6 cm from the reference plane B. This distance is provided with reference a.

Next, fig. 9 and 10 show a front view and a cross-sectional view of the discharge element 6. As can be seen in the cross-sectional view along section line X-X in FIG. 9: the overflow channel 10 extends with a first channel section 37 from the overflow inlet opening 9. The rising section 38 adjoins the first channel section 37. The rising section 38 leads to the overflow edge 11. After the overflow edge 11, the descending section 39 adjoins the ascending section 38. The descending section 39 then opens into the discharge channel 14 at the opening point 36. The ascending section 38 and the descending section 39 run parallel to one another here and, as already mentioned, are separated from one another by the partition wall 26.

It can also be seen from fig. 10: in the embodiment shown, the discharge channel 12 has a deflection section 40 which deflects the discharge channel in the direction of the overflow channel 20. The deflection section 40 makes it possible to place the opening 36 behind the closed wall section of the wall structure 8.
