Abstract
Description
Technical Field
[0001] This invention relates to a washbasin. Background Technology
[0002] Washbasin systems with corresponding water discharge devices are known from the prior art.
[0003] For example, DE102008044637 discloses a washbasin that can be connected to a drain pipe. For this purpose, the washbasin has a chamber into which water flows. The drain pipe is then adjacent to the chamber.
[0004] DE102008044637 has two main drawbacks. Firstly, the design of a washbasin with a cavity can only be manufactured in a very costly manner. This is especially true when manufacturing ceramic washbasins, where various undercuts significantly increase manufacturing costs. Secondly, a disadvantage is the relatively large installation space required. This is particularly true because the drain pipe is designed with bends.
[0005] Another washbasin is known from DE202008008557U1, which has a connector that is adjacent to the drain section of the washbasin and is substantially rearward away.
[0006] Furthermore, washbasins with overflow elements are known from the prior art. For example, EP1754838 discloses a drainage device for a washbasin with an overflow element that is rearwardly adjacent to the washbasin. Such overflow elements are typically located behind the front wall and are difficult to access in the installation position. Summary of the Invention
[0007] Based on the prior art, the objective of this invention is to provide a washbasin device that overcomes the shortcomings of the prior art. In particular, the objective of this invention is to provide a washbasin device with an overflow element, wherein the washbasin device should be formed more compactly overall.
[0008] A washbasin device includes: a washbasin having a basin, a cavity, and a drain passage extending from the basin into the cavity; and a drain element disposed in the cavity for guiding water away from the drain passage and for conveying water to a drain line. The washbasin has a rear wall that, in its installed position, allows contact with a connection structure on a building side via the rear wall. The cavity is formed in an open manner in a region of the rear wall of the washbasin, and the drain element has a wall structure extending across the cross-section of the drain passage. An overflow inlet is disposed at the wall structure. An overflow channel with an overflow edge is adjacent to the overflow inlet. Furthermore, a drain opening is provided in the wall structure, and a drain channel capable of being opened and closed using a shut-off valve is adjacent to the drain opening.
[0009] By placing the discharge element with a shut-off valve and the overflow channel with an overflow edge within the cavity, the following advantages are achieved: a very compact washbasin unit can be realized. This is especially true compared to an arrangement where the overflow unit is located behind the front wall. Furthermore, maintenance friendliness is increased.
[0010] The washbasin assembly includes: a washbasin having a basin, a cavity, and a drain passage extending from the basin into the cavity; and a drain element disposed in the cavity for guiding water away from the drain passage and for conveying water to a drain line. The washbasin also has a rear wall, which, in its installed position, allows contact with a connection structure on the building side. The cavity is formed in an open manner in the area of the rear wall of the washbasin. The drain element has an overflow channel with an overflow edge, wherein the overflow channel and the overflow edge are located within the cavity.
[0011] Preferably, the discharge element further has a wall structure extending across the cross-section of the discharge passage, wherein an overflow inlet opening is provided in the wall structure, an overflow channel with an overflow edge is adjacent to the overflow inlet opening, and wherein a discharge opening is present in the wall structure, and a discharge channel that can be opened and closed by a shut-off valve is adjacent to the discharge opening.
[0012] When the shut-off valve is closed, the water in the basin rises and flows into the overflow channel through the overflow inlet. The water then rises both in the basin and in the overflow channel. The overflow edge limits the maximum accumulation height in the basin. Upon reaching the maximum accumulation height, the water then flows out through the overflow edge. The height of the overflow edge limits the maximum accumulation height.
[0013] In the insertion position, the overflow channel preferably extends upward within the cavity. The overflow channel is preferably entirely located within the cavity.
[0014] Preferably, the drain passage of the water basin is located on the side wall of the water basin and extends substantially backward away from the water basin when viewed from the installed position. Preferably, the drain passage has a slight inclination of up to 20° relative to the horizontal plane.
[0015] Preferably, the shut-off valve is located in the cavity and / or in the discharge passage.
[0016] Preferably, the water basin is defined by an upper edge that lies in a horizontal plane at the insertion position. The edge extends across a reference plane. Here, viewed perpendicularly to the reference plane, the distance from the overflow edge to the reference plane is 3 to 6 centimeters.
[0017] Preferably, the entire emission element is substantially entirely located within the cavity. In particular, the emission element does not penetrate the plane spanned by the rear wall. Furthermore, the emission element does not protrude downwards from the cavity. If the emission element has an emission connector, this connector can be configured such that it protrudes outwards from the cavity as the sole element of the emission element. Here, the emission connector can extend rearwards and / or downwards from the cavity. However, apart from the emission connector, all other elements are preferably located within the cavity.
[0018] Preferably, the washbasin also has a bottom wall, wherein the bottom wall is formed in a downwardly open manner in the area where it is installed in the cavity, and wherein the drain element does not extend downward beyond the plane spanned by the bottom wall. If the drain element has a drain fitting, as already mentioned, the drain fitting can be configured such that it protrudes outward from the cavity as the sole element of the drain element, and hereby penetrates the plane spanned by the bottom wall according to design.
[0019] Preferably, when viewed from the loading position, the overflow channel extends only above the plane spanned by the bottom wall.
[0020] Preferably, the cavity is defined at the top by a wall area of the washbasin. The wall area has an outer surface. Preferably, the overflow edge is at most 3 cm or 6 cm from the outer surface. Preferably, the wall area has a through opening for leading the inlet line to the water outlet fitting and / or for leading the shut-off valve actuator rod.
[0021] The cavity is adjacent to the discharge passage. In a preferred embodiment, the cavity has a first space segment and a second space segment. Here, the first space segment is located between the discharge passage and the second space segment. Preferably, viewed from the first space segment, the support wall portion described herein extends into the second space segment. The overflow edge is preferably located in the second space segment. Viewed in the installed position, the second space segment extends upward relative to the first space segment.

[0023] Preferably, the overflow channel and the discharge channel enter into each other and continue to extend toward the discharge pipe joint as a common channel, wherein the entry points of the overflow channel and the discharge channel are located in the cavity.
[0024] Particularly preferably, the discharge connector is configured such that it does not penetrate the plane spanned by the rear wall. In this variation, the discharge connector is either entirely within the cavity or protrudes downwards and outwards from the cavity.
[0025] Preferably, the discharge connector is the only element protruding from the cavity from the discharge element, wherein, apart from the discharge connector, the discharge element is entirely located within the cavity.
[0026] The drain pipe fitting is used to connect to the drainage pipe. Preferably, the drain pipe fitting is disposed in a cavity.
[0027] Preferably, when viewed in the direction of water flow, the shut-off valve is located in front of the discharge opening or in the discharge channel.
[0028] Preferably, viewed from the emission passage, the emission opening is centrally located within the wall structure, and its lower edge is at or below the height of the lower wall portion of the emission passage.

[0050] Figure 10 It shows along Figure 9 A sectional view of section line XX. Detailed Implementation
[0051] exist Figure 1 The image shows a washbasin device 1 according to the present invention. The washbasin device 1 includes a washbasin 2 and a drain element 6.
[0052] The washbasin 2 has a sink 3, a cavity 4, and a drainage passage 5. Figure 1 In the cavity, only part of the cavity 4 is visible behind the discharge passage. The discharge element 6, used to guide water away, is disposed in the cavity 4. Water can be delivered to the discharge line (not shown) via the discharge element 6. The discharge passage extends from the water basin 3 into the cavity 4, allowing water to be guided from the water basin into the cavity 4 or to the discharge element 6.
[0053] The sink 3 is defined on the upper side by an upper edge 15. In the installed position, the upper edge 15 is located in the horizontal plane H. The installed position means that it is in an installed and ready-to-use state. In the rear area, the washbasin also has a wall area 17. The wall area 17 defines a cavity 4 at the top. The wall area has an outer surface 18 at the top, which is preferably also located in the reference plane B. In the illustrated embodiment, the wall area 17 has a through opening 19. The through opening 19 opens into the cavity 4 and is used to guide the inlet line to the water outlet fitting and / or to guide the shut-off valve actuator rod.
[0054] exist Figure 2 The washbasin unit 1 is shown from the rear. The washbasin 2 has a rear wall 7 at the rear. In the installed position, the washbasin 2 can contact the connecting structure on the building side via the rear wall 7. The washbasin 2 also has a bottom wall 16.
[0055] As from Figures 2 to 4 It is evident that 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 also formed in an open manner in the region of the bottom wall 16.
[0056] Regarding the cavity, the discharge element 6 is substantially entirely disposed within the 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 or the plane spanned by the bottom wall 16. This is without considering the discharge pipe or discharge pipe fitting, through which water is delivered to the drain pipe. Here, the discharge pipe fitting 21 extends downward from the cavity 4. Furthermore, the discharge element 6 partially extends into the discharge passage 5.
[0057] like Figures 2 to 6As shown, in the illustrated embodiment, the discharge element 2 has a wall structure 8 that extends completely across the cross-section of the discharge passage 5 when connected to the washbasin 2. In the illustrated embodiment, the discharge element 2 has two fastening openings 31 through which the discharge element 2 can be connected to the washbasin.
[0058] 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 molded from plastic.
[0059] A discharge opening 12 is provided in the wall structure 8. A discharge channel 14 is adjacent to the discharge opening 12. An embodiment is shown in the figures where 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 here has a valve disc shape. However, the shut-off valve 13 can be formed in other ways and, for example, located in the discharge channel 14. The shut-off valve 13 is used to seal the discharge opening 12 or the discharge channel 14, regardless of the design or location of the shut-off valve 13. When the shut-off valve 13 is closed, water accumulates in the basin 3. When the shut-off valve 13 is open, water flows out into the discharge channel 14.
[0060] When a certain accumulation height is reached with the shut-off valve closed, the overflow channel 10 is used to drain water from the basin 3. For this purpose, the overflow channel 10 has an overflow edge 11. The location of the overflow edge 11 defines the maximum accumulation height in the basin 3. In the illustrated embodiment, both the overflow channel 10 and the overflow edge 11 are located within the cavity 4. An overflow inlet opening 11 is provided in the wall structure 8, and the overflow channel 10 is adjacent to this overflow inlet opening. Subsequently, the overflow channel 10 extends upwards to the overflow edge 11 and then downwards again from the overflow edge 11.
[0061] In the illustrated embodiment, the overflow inlet 11 and the discharge outlet 12 are configured as separate openings. Here, viewed from the basin 3 or the discharge passage 5, the overflow passage 10 can be accessed via the overflow inlet 9, and the discharge passage 14 can be accessed via the discharge outlet 12. The overflow inlet 9 and the discharge outlet 12 are laterally offset from each other and are arranged adjacent to each other. This means that the overflow inlet 9 and the discharge outlet 12 are a distance apart from each other.
[0062] Overflow passage 10 and discharge passage 14 enter each other at inlet 36 and continue as a common passage 20 toward discharge connector 21 after inlet 36. The inlets of overflow passage 10 and discharge passage 14 are also located within the cavity 4. The discharge pipe can then be adjacent to discharge connector 21. Here, viewed along the flow direction from overflow inlet 9 and discharge outlet 12, inlet 36 is located behind overflow edge 11 and shut-off valve 13.
[0063] The discharge opening 12 and the overflow inlet opening 11 are positioned such that they are within the clear width of the discharge passage 5 in their installation positions. This means that water can flow unimpeded from the discharge passage 5 to the discharge opening 12 and the overflow inlet opening 11. Viewed from the discharge passage 5, the discharge opening 12 is centrally located in the wall structure 8, and its lower edge 22 is at or below the height of the lower wall portion 23 of the discharge passage 5. Furthermore, the overflow inlet opening 9 is laterally located next to the discharge opening 12, and its lower edge 24 is at or below the height of the lower wall portion 23 of the discharge passage 5.
[0064] like Figure 5 and 6 As clearly shown, the overflow channel 10 is laterally surrounded by the wall portion 25. The wall portion 25 extends upward over the wall structure 8. The partition wall 26 extends laterally through the interior space 27 defined by the wall portion 25. The partition wall 26 has the overflow edge 11. The overflow channel 10 is closed upward by means of a cover 28. Here, the inner side 29 of the cover is spaced apart from the overflow edge 11.
[0065] A support wall portion 30 protrudes from the wall structure 8. Here, the support wall portion 30 extends into the cavity 4 of the washbasin. The support wall portion 30 is formed on its outer side in a manner that matches the shape of a first spatial segment of the cavity 4. The first spatial segment is adjacent to the drain passage 5. Preferably, the range of the first spatial segment for accommodating the support wall portion 30 is slightly larger than the range of the drain passage 5 directly adjacent to the sink 3. The remaining portion of the drain element 6 is located in a second spatial region of the cavity, wherein the second spatial region is adjacent to the first spatial region.
[0066] The support wall portion 30 is formed as a circumferential support wall portion and is also used to accommodate a sealing element 32 that is also circumferential. The sealing element 32 is configured to work in conjunction with the wall of the cavity 4.
[0067] exist Figure 7 A cross-sectional view through the exhaust channel is shown. Then, Figure 8 A cross-sectional view showing the overflow channel is shown. (See attached image.) Figure 8 As shown, the distance from the overflow edge to the reference plane B is 3 to 6 centimeters. This distance is indicated by reference numeral A in the attached diagram.
[0068] Then, Figure 9 and Figure 10 The front view and cross-sectional view of the emission element 6 are shown. From Figure 9 As can be seen in the cross-sectional view along section line XX: the overflow channel 10 extends from the overflow inlet opening 9 via a first channel section 37. A rising section 38 is adjacent to the first channel section 37. The rising section 38 leads to the overflow edge 11. After the overflow edge 11, a descending section 39 is adjacent to the rising section 38. The descending section 39 then enters the discharge channel 14 at the inlet 36. The rising section 38 and the descending section 39 extend parallel to each other and, as already mentioned, are separated from each other by a partition wall 26.
[0069] from Figure 10 It can also be seen that, in the illustrated embodiment, the discharge channel 12 has a deflection section 40 that deflects the discharge channel toward the overflow channel 20. This deflection section 40 allows the inlet portion 36 to be positioned behind the enclosed wall section of the wall structure 8.
