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 easy-to-maintain drainage element.

[0008] Therefore, 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 drain element has a drain passage accessible via a drain opening, the drain passage having a shut-off valve. The shut-off valve includes a valve seat and a closing mechanism. The valve seat and the closing mechanism are at least partially, and in particular completely, located in the cavity and / or the drain passage.

[0009] By placing the closure mechanism and valve seat in the cavity or in the outflow passage, the following advantages are obtained: the shut-off valve can be easily accessed through the discharge passage for cleaning or maintenance work.

[0010] Particularly preferably, the valve seat is located within the cavity. The closing mechanism is also located within the cavity in the closed position and extends from the cavity into the discharge passage in the open position.

[0011] Preferably, when viewed from the water basin, the valve seat is located at a small distance of a few centimeters, especially a maximum of 5 to 10 centimeters, from the inlet opening into the discharge passage.

[0012] Preferably, a seal is provided between the valve seat and the sealing mechanism.

[0013] Preferably, the valve seat is inclined at an angle relative to the central axis of the discharge passage or the flow direction, wherein the angle is preferably such that the lower edge is ahead of the upper edge when viewed in the direction of water flow, wherein the upper edge is above the lower edge in the inserted position.

[0014] The angled arrangement provides the following advantage: water can easily flush away solids (such as hair) that reach the valve seat.

[0015] Preferably, the valve seat is located inside the discharge passage. Alternatively, the valve seat is laterally positioned around the discharge opening.

[0016] Preferably, the closure mechanism is a valve disc capable of pivoting about a rotating shaft extending along a central axis, wherein the rotating shaft is preferably located above a valve seat in the installation position. Thus, the rotating shaft is only submerged in water in the event of accumulation, but not in water during normal flow, which significantly reduces its susceptibility to calcification.

[0017] Preferably, the valve disc can be moved from a closed position to an open position via the pivoting movement toward the discharge passage. In the case of water accumulation in the basin, the valve disc is pressed against the valve seat by water pressure, and must overcome the water pressure when moving from the closed position to the open position.

[0018] Preferably, the rotating shaft is supported in at least one support portion provided by a wall structure surrounding the discharge channel. Here, the support portion is preferably an integral part of the wall structure, that is, embedded in the wall structure.

[0019] Preferably, the support portion has a first receiving portion for a first support section of the rotating shaft and a second receiving portion for a second support section of the rotating shaft. Preferably, the first support section is located at the free end of the rotating shaft and the first receiving portion is a recess in the wall structure. The second support section is preferably provided by a section of the rotating shaft opposite to the free end, wherein the second receiving portion is provided by an opening in the wall structure. Preferably, a sealing element is provided in the area of ​​the opening and in the second support section.

[0020] Preferably, the valve disc has a receiving opening into which a rotating shaft can be inserted and torsionally connected with the valve disc. Preferably, the rotating shaft has at least one comb-shaped section that engages with a grooved section in the receiving opening. This engagement achieves a torsion-resistant connection.

[0021] Preferably, the rotating shaft has an actuation section located outside the discharge channel, wherein the actuation section has an opening offset relative to the central axis of the rotating shaft, and one end of the actuation rod can be inserted into the opening.

[0022] Preferably, the actuating section is opposite to the free end of the first supporting section.

[0023] Preferably, the discharge element has a receiving structure for accommodating a support element. The support element has a guide section in which an actuating rod for actuating the closing mechanism is supported.

[0024] Preferably, the support element can be inserted into and locked in the receiving structure.

[0025] Preferably, the closing mechanism is movable to a flow position, in which it engages with the discharge element using a locking connector. In the flow position, the closing mechanism is spaced apart from the valve seat and the discharge passage is opened. This provides the advantage that the discharge element can be inserted into a washbasin unit where there is no buildup. In this case, the closing mechanism can be easily deactivated by its movable flow position. If a discharge element without buildup is used, the support element and actuator rod can be eliminated.

[0026] Preferably, the closing mechanism is movable from an open position to a closed position, wherein in the open position the closing mechanism is spaced apart from the valve seat and opens the discharge passage, and in the closed position the closing mechanism is located on the valve seat and blocks the discharge passage.

[0027] Preferably, the closing mechanism can move from the open position to the flow position, in the opposite direction to moving to the closed position.

[0028] Preferably, in the closed position, a portion of the closing mechanism contacts the stop. This limits the force acting on the closing mechanism. The stop is preferably part of a rotating shaft or actuating section.

[0029] Preferably, the emission element has a wall structure extending across the emission passage in cross-section, wherein the emission opening is provided in the wall structure. If an overflow inlet opening is present, such overflow inlet opening is also provided in the wall structure.

[0030] Preferably, the support wall protrudes from the wall structure, wherein the support wall extends into a sub-region of the cavity adjacent to the discharge passage, wherein the support wall defines the interior space, and wherein the closure mechanism is at least partially located within the interior space.

[0031] Preferably, the emission element is located substantially entirely within the cavity.

[0032] Optional features of the embodiment with an overflow channel are described below. Preferably, the discharge element also has an overflow channel with an overflow edge, wherein, viewed from the basin, the overflow channel can be accessed via an overflow inlet opening, and wherein the overflow inlet opening and the discharge opening are arranged laterally offset adjacent to each other.

[0033] Therefore, water flowing through the discharge path impacts the discharge opening and overflow inlet. The advantage of this separated arrangement is that the "discharge" and "overflow" functions are separated from each other by forming different channels. During operation, it is also possible for the discharge opening and / or discharge path to be damaged or even blocked by hair and other objects. Separating it from the discharge path ensures that, in the event of a blockage in the discharge path, water can be reliably guided away from the basin via the overflow path.

[0034] The discharge opening and the overflow opening are spaced apart from each other. The overflow opening and the discharge opening are two separate openings.

[0035] With the shut-off valve 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.

[0036] Preferably, when viewed from the filling position, the lower edge of the discharge opening is lower than the lower edge of the overflow inlet opening. This ensures that water can always flow out of the basin through the discharge channel when it is open.

[0037] Preferably, the overflow inlet and / or outlet openings extend substantially at least over the entire net height of the outlet passage. This maximizes the cross-sectional area of ​​each opening.

[0038] Preferably, the overflow channel and the discharge channel extend as separate channels after the overflow inlet or discharge outlet and, when viewed in the flow direction, enter into each other at the inlet after the overflow edge.

[0039] Preferably, the overflow channel and the discharge channel continue as a common channel toward the discharge pipe connector after the inlet. For example, the discharge pipe can be adjacent to the discharge pipe connector.

[0040] Preferably, the inlet of the overflow channel and the outlet of the discharge channel are located in the cavity of the washbasin.

[0041] Preferably, the overflow channel extends from the overflow inlet opening with a first channel section, wherein an ascending section leading to the overflow edge is adjacent to the first channel section, wherein a descending section following the overflow edge is adjacent to the ascending section, the descending section preferably extending parallel to the ascending section, wherein the descending section leads into the discharge channel.

[0042] Preferably, when viewed from the insertion position, the first channel section extends rearward in the direction of the discharge passage. The rising and falling sections extend substantially vertically or at a small angle to the vertical.

[0043] In one implementation variation, the access from the descending section to the emission channel is direct. This means that the descending section transitions directly into the emission channel. In an alternative implementation variation, the access is indirect. Here, an additional channel section is adjacent to the descending section, and this additional channel section then accesses the emission channel.

[0044] Preferably, the rising section and the falling section are separated from each other by a partition wall, wherein the upper end of the partition wall provides the overflow edge.

[0045] Preferably, when viewed from above, the overflow edge has an arc-shaped cross-section, wherein the overflow edge has at least one convex rounded section and / or at least one concave rounded section. The arc-shaped design provides the advantage that the overflow channel can be configured in a space-saving manner.

[0046] Preferably, the inlets of the overflow and discharge passages are located between the overflow inlet and the discharge outlet. This is especially true when viewed through the discharge passage. In the loading position, the inlets are located after the discharge passage.

[0047] Preferably, viewed in the direction of water flow, the discharge channel has a deflection section after the discharge opening, which deflects the discharge channel toward the overflow channel. Here, the deflection section can follow directly after the discharge opening or be located at a distance from the discharge opening.

[0048] As described above, the emission element preferably has a wall structure extending across the emission passage in cross section, wherein the overflow inlet and the emission outlet are disposed in the wall structure.

[0049] Preferably, the discharge passage and the overflow passage are rearwardly adjacent to the wall structure.

[0050] The following describes other preferred and further optional features of the washbasin unit:

[0051] Preferably, the sink has a rear wall that, in the installed position, allows the sink to contact the building-side connection structure via this rear wall, wherein a cavity is formed in an open manner in the rear wall region of the sink. Preferably, a drain element with a shut-off valve and an overflow channel with an overflow edge are substantially located within said cavity. The advantage of placing the drain element with a shut-off valve and, if necessary, an overflow channel with an overflow edge within the cavity is that a very compact washbasin unit can be achieved. This is especially true compared to arrangements where the shut-off valve unit or overflow unit is located behind the front wall. Furthermore, maintenance friendliness is improved.

[0052] Preferably, the wall structure extends across the cross-section of the discharge passage and correspondingly closes that cross-section, allowing water to flow out of the discharge passage only through the discharge opening and the overflow inlet opening. The discharge opening and the overflow inlet opening are located at least within the net width of the discharge passage.

[0053] In another variation, the overflow channel and overflow edge are essentially located within the cavity.

[0054] In the loading position, the overflow channel preferably extends upward within the cavity. The overflow channel is preferably entirely located within the cavity.

[0055] 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 direction.

[0056] Preferably, the shut-off valve is located in the cavity and / or in the discharge passage.

[0057] Preferably, the water basin is defined by an upper edge that lies in the horizontal plane in the inserted position. The edge extends across a reference plane. Here, viewed perpendicularly to the reference plane, the overflow edge is 3 to 6 centimeters away from the reference plane.

[0058] 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 protrude rearwards and / or downwards from the cavity. However, apart from the emission connector, all other elements are preferably located within the cavity.

[0059] Preferably, the washbasin also has a bottom wall, which is formed downwardly open in the region of the cavity in the installed position, 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.

[0060] Preferably, when viewed from the loading position, the overflow channel extends only above the plane spanned by the bottom wall.

[0061] 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 to 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.

[0062] 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.

[0063] The surface of the wall region extends substantially within the reference plane.

[0064] 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.

[0065] 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.

[0066] Preferably, the discharge connector is the only element from which the discharge element extends out of the cavity, wherein the discharge element is entirely located within the cavity except for the discharge connector.

[0067] The discharge pipe fitting is used to connect to the discharge pipeline. Preferably, the discharge pipe fitting is disposed in a cavity.

[0068] Preferably, the discharge opening is centered in the wall structure when viewed from the discharge passage, and its lower edge is at or below the height of the lower wall portion of the discharge passage.

[0069] Preferably, the overflow inlet is located laterally next to the discharge outlet, and its lower edge is at or below the height of the lower wall of the discharge passage.

[0070] Preferably, the wall structure is shaped such that the water to be discharged does not accumulate in front of the wall structure, but is always delivered to the discharge opening.

[0071] Preferably, the overflow channel is laterally surrounded by a wall portion, wherein the wall portion extends upward over the wall structure, and wherein a partition wall having an overflow edge extends laterally through the interior space defined by the wall portion.

[0072] The wall of the overflow channel preferably extends upward away from the wall structure.

[0073] Preferably, the overflow channel is closed upwards using a cover, wherein the inner side of the cover is spaced apart from the overflow edge by a distance.

[0074] The cover has the following advantages: when needed, the wall section can be mechanically shortened, and the overflow passage can then be closed by the cover. Therefore, the discharge element can be easily matched with different types of washbasins.

[0075] In a preferred embodiment, two overflow inlets and two overflow channels are provided. Here, the discharge opening with the discharge channel is located between the two overflow inlets or the two overflow channels.

[0076] Preferably, the support wall protrudes from the wall structure. Here, the support wall extends into the cavity of the washbasin. The support wall is formed on the outer side in a manner that matches the shape of the cavity. Preferably, the drainage passage for accommodating the support wall has a slightly larger extent than in the section directly adjacent to the sink.

[0077] The support wall is formed in a circumferential direction and also serves to accommodate a sealing element in the same circumferential direction. The sealing element is configured to interact with the wall of the cavity and / or with the rear wall.

[0078] Preferably, this sealing element is formed separately from the discharge element. Alternatively, at least one sealing element is integrally molded into the insertion element.

[0079] Preferably, the discharge element can be connected to the washbasin via a material-fitting adhesive connection and / or mechanical connection. The mechanical connection is preferably a bolted connection, a pin connection, and / or a clamping connection between the discharge element and the cavity. Attached Figure Description

[0103] exist Figure 1 The washbasin unit 1 is shown. The washbasin unit 1 includes a washbasin 2 and a drain element 6.

[0104] 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.

[0105] 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 cavity 4 is defined at the top by the wall area 17. 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.

[0106] 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.

[0107] 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.

[0108] 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 supplied to the discharge pipe. Here, the discharge pipe fitting 21 protrudes downward from the cavity 4. Furthermore, the discharge element 6 extends partially into the discharge passage 5.

[0109] In the illustrated implementation scheme, such as Figures 2 to 6 As shown, 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 it can be connected to the washbasin.

[0110] 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.

[0111] 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 accompanying drawings, wherein 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 and is referenced... Figures 11 to 22A more detailed explanation follows. 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 water basin 3. When the shut-off valve 13 is open, water flows out into the discharge channel 14.

[0112] 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.

[0113] 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 arranged laterally offset from each other and adjacent to each other. This means that the overflow inlet 9 and the discharge outlet 12 are a distance apart from each other.

[0114] 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.

[0115] 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 position. 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.

[0116] like Figure 5 and 6As 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 a cover 28. Here, the inner side 29 of the cover is spaced apart from the overflow edge 11.

[0117] 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.

[0118] 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.

[0119] exist Figure 7 The image shows a cross-sectional view through the emission channel. Then, Figure 8 A cross-sectional view through 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.

[0120] 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.

[0121] 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.

[0122] According to a particularly preferred implementation scheme, Figures 11 to 22 Other features of the shut-off valve 13 are described in more detail below.

[0123] The shut-off valve 13 includes a valve seat 41 and a closing mechanism 42. The valve seat 41 and the closing mechanism 42 are at least partially, and especially completely, located in the cavity 4 and / or the discharge passage 5.

[0124] The valve seat 41 is tilted at an angle α relative to the central axis of the discharge passage or relative to the flow direction. The tilt angle is preferably such that, when viewed in the direction of water flow, the lower edge 22 is ahead of the upper edge 43, wherein the upper edge is above the lower edge 22 in the inserted position. The angle α is preferably between 5° and 45°.

[0125] The closing mechanism 42 can be actuated by an actuating rod 53. Here, the actuating rod 53 is movably supported at the support element 55. The support element 55 can be connected to the discharge element 6. The discharge element 6 has a receiving structure 54 into which the support element 55 can be inserted. The receiving structure 54 is designed as a longitudinal guide 58, and the support element 55 has a guide section 59 into which the support element 55 can be inserted. A locking connector 62 is provided between the longitudinal guide 58 and the guide section 59, by means of which the support element 55 can be locked relative to the discharge element.

[0126] like Figure 12 As shown, the actuating rod 53 engages with the opening 52 at the actuation section 51 of the rotating shaft 44. When the actuating rod moves, the rotating shaft 44 can move accordingly from the open position to the closed position.

[0127] In the illustrated embodiment, the closing mechanism 42 is a valve disc. The valve disc is pivotable about a rotation shaft 44 extending along a central axis. Here, the valve disc can be connected to the rotation shaft 44. Viewed in the installed position, the rotation shaft 44 is located on the valve seat 41.

[0128] exist Figure 13 The diagram shows a cross-sectional view passing through the central axis of the rotating shaft 44. The rotating shaft 44 is supported at the discharge element by two support portions 45. One of the support portions 45 has a receiving portion 46 for a first support section 47 of the rotating shaft 44. The first support section 47 is designed with a free end and extends into the receiving portion 46. The second support portion 45 has a second receiving portion 48 for a second support section 49 of the rotating shaft 44. Furthermore, a sealing portion 60 is provided in the area of ​​the second receiving portion 48.

[0129] The rotating shaft 44 extends between the support sections 47 and 49 through a receiving opening 50 at the valve disc. Here, the rotating shaft 44 is located in the receiving opening 50 with anti-torsional properties. In the illustrated embodiment, the rotating shaft 44 has a plurality of comb-shaped members that engage with grooves at the receiving opening 50.

[0130] The rotating shaft 44 has an actuating section 51 at its end. The actuating section 51 is located outside the discharge channel 14. The actuating section 51 has the aforementioned opening 52, into which one end of the actuating rod 53 engages. The opening 52 is laterally offset relative to the central axis of the rotating shaft 44.

[0131] exist Figures 11 to 22 The shut-off valve shown can basically occupy three positions, i.e., according to Figures 14 to 17 The distribution location, according to Figure 18 and Figure 19 The opening position and according to Figures 20 to 22 The closed position.

[0132] In the flow position, the closing mechanism 42 is securely locked to the discharge element 6. Preferably, the closing mechanism 42 is then placed in the flow position when accumulation in the water basin 3 is not desired. If accumulation is not desired, the elements for actuating the closing mechanism 42 can be omitted. For example, the arrangement of support elements and actuating rods can be omitted. To move to the flow position, the closing mechanism 42 moves from the open position in the opposite direction to the movement to the closed position. This means that, viewed from the loading position, the closing mechanism is preferably higher in the flow position than in the closed position.

[0133] In the closed position, the closing mechanism locks relative to the discharge element at the locking connector 56. Figure 17 The locking connector 56 is shown. The locking connector 56 is located on the rear side of the discharge element 6. Here, the actuating section 51 is locked in the wall region of the discharge element 6.

[0134] When the desired accumulation function is desired, the closing mechanism 42 can move back and forth between an open position and a closed position. For actuation, the actuation rod 53 can be connected to the discharge element 6 together with the support element 55. In the closed position, the closing mechanism 42 contacts the stop 57. The stop 57 is provided by a portion of the actuation section 51 and a portion of the wall region of the discharge element 6, and... Figure 22 As can be seen, the stop ensures that excessive closing force on the closing mechanism is prevented.

[0135] As mentioned, the emission element 6 has a support wall 30 that protrudes from the wall structure 8. The support wall 30 extends into a sub-region of the cavity 4 adjacent to the emission passage 5. The support wall 30 defines an interior space 61 in which the closure mechanism 42 is at least partially located. In the closed position, the closure mechanism 42 is substantially entirely located within the interior space 61. In the open and open positions, the closure element 42 protrudes from the interior space 61 in the direction of the emission passage 5 and extends into the emission passage 5. This is from Figure 16 and Figure 19 As can be seen in the text.
