The hollow column is positioned on the spring core and connected to the spring core via a connection mechanism.

[0006] However, a disadvantage of this design is that it is complex and prone to contamination. Therefore, an object of the present invention is to provide a drain valve and a sanitary basin with a drain valve that allow for easy cleaning of the drain cup while simultaneously offering a simple design and high flexibility for use with different basin thicknesses.

[0007] Another object of the present invention is to provide an alternative drain valve and an alternative sanitary basin with drain valve.

[0008] In one embodiment, the present invention solves the aforementioned problems in a drain valve for arrangement in a drain opening of a sanitary basin, in particular a sink, comprising a valve top and a valve bottom which can be connected to the valve top or is formed integrally with it, wherein a drain opening is arranged in the valve top which can be closed by means of a closing device, in that in the area of ​​the valve top the valve top and / or the valve bottom is formed at least in two parts with at least a first and a second part, wherein the first and the second part can be fixed to each other by force and / or form locking.

[0009] In one embodiment, the present invention also solves the aforementioned problems with a sanitary basin, in particular a sink with a drain opening and a drain valve according to one of claims 1-24, which is arranged at the drain opening.

[0010] One of the advantages achieved is easier cleaning and greater operational reliability. Furthermore, this allows for a simpler layout, and the parts can be manufactured independently and adapted to specific requirements.

[0011] Further features, advantages, and embodiments of the invention are described below or become apparent therein. According to an advantageous embodiment of the invention, the first part is configured as a radially inner part and the second part as a radially outer part, in particular wherein the first part forms at least part of a base of the valve head. One of the advantages thereby achieved is the simple assembly of the two parts. The term "radially inner" with respect to a part is understood to mean, in particular, a part which is wholly or partially surrounded, at least in one plane, by another part. In particular, the term "radially inner" does not refer exclusively to a circular shape of the part.

[0012] According to a further advantageous embodiment of the invention, at least the first and second parts can be detachably fixed to one another. This allows the first part to be removed, so that it can be easily detached by a user without having to disassemble the entire valve. This enables thorough cleaning of the previously difficult-to-reach areas of the drain valve. For the first time, the user can thus clean deeper areas of the drain valve, preventing the accumulation of dirt and significantly improving hygiene.

[0013] According to a further advantageous embodiment of the invention, the first and second parts can be fastened to one another by means of a bayonet fitting, a clip and / or snap-fit ​​connection, and / or a screw connection. This enables a simple yet reliable detachable connection of the two parts.

[0014] According to a further advantageous embodiment of the invention, a guide device for guiding a closure for closing the drain opening is arranged on the valve upper and / or the valve lower part. The advantage of this is a particularly reliable actuation of the closure.

[0015] According to a further advantageous embodiment of the invention, the guide device is arranged on at least one of the two parts, in particular on the first part. One of the advantages of this is reliable guidance of the closure and, in particular, easier cleaning of the guide device when it is arranged on the first part. According to a further advantageous embodiment of the invention, the guide device has an opening, in particular a vertical one, for guiding a closure. One of the advantages of this is simple and reliable guidance of the closure.

[0016] According to a further advantageous embodiment of the invention, the guide device has at least one, and in particular two, vertical projections, wherein the two vertical projections are arranged on opposite sides of a base of the valve upper and / or the valve lower part. This enables extremely reliable guidance of the closure. For example, the guide device can have a T-shaped or cross-shaped cross-section.

[0017] According to a further advantageous embodiment of the invention, the at least one vertical projection has a cross-section that deviates from circular symmetry and / or, in particular, rib-like radial projections are arranged on the at least one vertical projection. This further improves the manual handling of the first part by a user.

[0018] According to a further advantageous embodiment of the invention, the first part has a star-shaped division with at least three, in particular at least five, and in particular six or seven, partial openings. The advantage of this is a dirt-trapping function for the drain opening of the first part, while simultaneously providing sufficiently large openings for the drainage of wastewater.

[0019] According to a further advantageous embodiment of the invention, the first part has a cross-sectional area whose size is less than or equal to the cross-sectional area of ​​the closure for closing the partial openings. For example, the closure, particularly considering circumferential seals arranged on it, can completely cover the openings of the first part, and in particular the entire first part, thus reliably closing the drain valve. According to a further advantageous embodiment of the invention, the first part has an anti-rotation device such that when the closure is turned, a rotational movement of the first part is at least inhibited, and in particular prevented. The advantage of this is, firstly, its high value for the user, and secondly, it simplifies or facilitates the operation of the closure.

[0020] According to a further advantageous embodiment of the invention, the anti-rotation device is designed in the form of a cross-sectional shape of the first part that deviates from a circular shape. In this way, a particularly simple embodiment of an anti-rotation device can be provided.

[0021] According to a further advantageous embodiment of the invention, the valve lower part and the valve upper part can be positively locked to one another. This allows for a simple and reliable fastening of the two valve parts to one another, for example by means of clamping and / or by means of a snap-fit ​​connection.

[0022] According to a further advantageous embodiment of the invention, an adjustment device is arranged with which at least one of the valve parts, in particular the valve head, can be fixed to the drain opening. This allows the drain valve to be easily fixed to the basin.

[0023] According to a further advantageous embodiment of the invention, the adjusting device comprises a nut and the at least one valve element a thread, in particular an external thread, for engagement of the nut. The advantage of this is the simple positioning of the drain valve even with varying material thicknesses of the basin.

[0024] According to a further advantageous embodiment of the invention, a drain cup is arranged above the valve base, detachably positioned within the valve head. The advantage of this is that the drain cup is particularly easy to remove and quick to clean. Dirt can thus be retained closer to the user, further simplifying cleaning. According to a further advantageous embodiment of the invention, the closure device has an actuating element for operating the closure, wherein the distance between a region of the valve head that rests on the drain opening and the actuating element in a position where the closure device closes the drain valve is the same for different material thicknesses of the sanitary basin in the area of ​​the drain opening. One of the advantages achievable with this is high flexibility with regard to adaptability to different basin thicknesses.Furthermore, the user experience is improved because tolerance compensation for different sink thicknesses is no longer necessary, and simple operation is enabled.

[0025] According to a further advantageous embodiment of the invention, the drain cup can be positively locked to the valve head, in particular by means of clamping. The advantage of this is the simple and quick removal of the drain cup for cleaning.

[0026] According to a further advantageous embodiment of the invention, the closure has a connecting element for attaching a sieve basket, in particular wherein the connecting element is designed as a cuboid-shaped projection. One of the advantages achieved thereby is that a sieve basket or the like can be flexibly arranged on the closure, in particular detachably.

[0027] According to a further advantageous embodiment of the invention, at least one seal is arranged between the valve upper and lower parts and / or between a drain cup and an edge of the drain opening. The advantage of this is a reliable seal between the respective components.

[0028] According to a further advantageous embodiment of the invention, the drain cup has a cup-shaped drain opening with a star-shaped division comprising at least three, in particular at least five, and in particular at least seven, partial openings, which can be closed by means of the closing device. The advantage of this is a dirt-trapping function while simultaneously providing sufficiently large openings for the drainage of wastewater. According to a further advantageous embodiment of the invention, the drain valve is designed for the subsequent installation of an actuating device, in particular wherein the actuating device is arranged in the valve base. This enables, on the one hand, simple retrofitting with an actuating device, for example in the form of a remote control device with Bowden cable.

[0029] According to a further advantageous embodiment of the invention, the drain valve has an opening that can be opened and / or closed. This allows for retrofitting in a particularly cost-effective manner, as a user or a technician can open the opening, which is currently closed but intended to be opened, for example by cutting it open, and then simply insert the remote control unit.

[0030] Further important features and advantages of the invention will become apparent from the dependent claims, the drawing and the accompanying description of the figures based on the drawing.

[0031] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0032] Preferred embodiments and configurations of the present invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components or elements.

[0033] This is shown in schematic form

[0034] Figure 1 shows a cross-sectional section of a sanitary basin according to an embodiment of the present invention; Figure 2 shows a three-dimensional view of a sanitary basin according to an embodiment of the present invention;

[0035] Figure 3 shows a section of a drain cup in cross-section according to an embodiment of the present invention;

[0036] Figure 4 shows a cross-sectional section of a drain cup according to an embodiment of the present invention; and

[0037] Figure 5 shows a section of a sanitary basin in cross-section according to the embodiment of Figure 2.

[0038] Figure 1 shows a section of a sanitary basin according to an embodiment of the present invention.

[0039] Figure 1 shows in detail a basin in the form of a sink 3 with a drain opening 2, in which a drain valve 1 is arranged. The drain valve 1 has a valve upper part 4 and a valve lower part 5, which are connected to each other by means of a positive engagement of the valve lower part 5 with the valve upper part 4. The valve upper part 4 projects downwards through and beyond the drain opening 2 of the sink 3. Furthermore, a circumferential seal 18 is arranged between the valve upper part 4 and the valve lower part 5.

[0040] To adapt to different thicknesses of the sink, an adjusting device 13 is provided. This device has a thread 15 on the radial outer surface of the essentially cup-shaped valve head 4. By means of a nut 14, which engages in the thread 15, the valve head 4 can be clamped, i.e., fixed, to the drain opening 2 of the sink 3 from below, thus also securing the drain valve 1 as a whole. A circumferential seal 19 is arranged between the bearing part 22 of the valve head 4 on the drain opening 2 of the sink 3 and the part of the sink 3 surrounding the drain opening 2 of the sink 3. A drain cup 6 is arranged in the valve head 4, which has a central opening 23 in its base region, from which a star-shaped division 20 of the remaining annular opening is arranged.To close the bottom openings 20, 23 of the drain cup 6, which form a cup drain opening 24, a sealing plug 7 with a cross-section essentially T-shaped is provided, which closes the cup drain opening 24 with a horizontal section and is guided with its vertical part in the central opening 23 to open and close the cup drain opening 24.

[0041] For vertical movement of the sealing plug 7, a lever device 9 is provided next to a drain pipe 8. This lever device engages the vertical part of the sealing plug 7 by means of a movable lever 11. With a corresponding up-and-down movement of the lever 11, the sealing plug 7 is moved upwards (open position, drain opening 24 is open) or downwards (closed position, drain opening 24 is closed). The lever device 9 can be actuated, for example, by a remote control device in the form of a Bowden cable 21.

[0042] The sealing plug 7 has a cuboid projection 16 on the side of the horizontal part 42 facing away from the vertical part 41, on which a sieve basket 17 can be detachably, for example by friction, arranged on the projection 16.

[0043] Furthermore, a guide, for example a guide insert 12, can be provided between the lever element 11 and the lower edge of the drain cup 6. This guide insert 12 is detachably arranged on the valve lower part 5 in the area of ​​the valve upper part 4, specifically in the lower region. It additionally guides the vertical part of the sealing plug 7 in the area below the drain cup 6 in a vertical direction. The guide insert 12 is located in a drain opening 25 of the valve upper part 4. The guide insert 12 can be mounted on a circumferential projection on one of the valve parts 4, 5, or it can be positively engaged, wedged, etc., and can be removed.

[0044] The drain valve 1 with its valve top 4 is designed such that a distance 10 starting from the height of an edge of the valve top 4, for example a sealing edge or a bearing area of ​​the valve top 4 on the sink 3, in a vertical direction down to a lower level, for example the lever element 11 or a lower edge of the valve bottom 5, is constant for different sink thicknesses.

[0045] Figure 2 shows a section of a sanitary basin in a three-dimensional view according to an embodiment of the present invention, and Figure 5 shows a section of a sanitary basin in cross-section according to the embodiment of Figure 2.

[0046] Figures 2 and 5 show in detail a section of a basin in the form of a sink 3 with a drain opening 2, in which a drain valve 1 is arranged. The drain valve 1 has a valve upper part 4 and a valve lower part 5, which are connected to each other by means of a positive engagement of the valve lower part 5 with the valve upper part 4. The valve upper part 4 projects downwards through and beyond the drain opening 2 of the sink 3.

[0047] To adapt to different sink thicknesses, an adjustment device 13 is arranged analogously to Figure 1, but is not explicitly described here. The valve head 4 has a drain opening 25 in its base and is formed in two parts, a first part 30 and a second part 31. The first part 30 essentially forms the base of the valve head 4. The first part 30 can be detachably fixed in the drain opening 25 by means of a bayonet connection 32, comprising recesses 34 in the second part 31 into which projections 33 can engage. The first part 30 is disc-shaped and has a star-shaped division (not shown here) with at least three, in particular at least five, and in particular six or seven, partial openings. A vertical projection 36 is arranged in the center of the first part 30, which serves as a guide 35 for the vertical part 41 of the T-shaped sealing plug 7.Furthermore, the projection 36 is not completely cylindrical, but has two opposing flattened sections, which are provided with horizontally circumferential and radially projecting ribs 38. These serve to grip and actuate, in particular rotate, the first part 30, for example to remove it from the second part 31 without tools.

[0048] To close the openings of the first part 31, the sealing plug 7 has a horizontal section 42 which has a circumferential seal 43 and which, when arranged in the second part 31, completely covers the first part 30 from above together with the horizontal section.

[0049] A lever mechanism can be provided for vertical movement of the sealing plug 7, analogous to Figure 1. However, in Figures 2 and 5, the sealing plug 7 can be removed manually, for example by rotating it in the horizontal plane and / or moving it vertically upwards.

[0050] The sealing plug 7 has a cuboid projection 16 on the side of the horizontal part 42 facing away from the vertical part 41. A strainer basket can be detachably attached to this projection 16, for example by friction, as shown in Figure 1. To open the drain opening 25, the strainer basket, or the sealing plug 7 if no strainer basket is attached, can be manually rotated horizontally by a user for easier removal and / or moved vertically upwards.

[0051] Figure 3 shows a section of a drain cup in cross-section according to an embodiment of the present invention, and Figure 4 shows a section of a drain cup in cross-section according to an embodiment of the present invention.

[0052] Figures 3 and 4 essentially depict a valve top 4 according to Figure 2. In contrast to Figure 2, in the valve top 4 of Figure 3, the first part 30 is detachably fixed in the second part 31 by means of a clip and / or snap-fit ​​connection. For this purpose, the first part 30 has a recess 44 that extends at least partially horizontally around its circumference and can engage in a corresponding horizontal projection 45. To prevent the first part 30 from rotating with the second part 31 due to friction when the sealing plug 7 is turned, the first part 30 can be non-circular. The term "non-circular" refers in particular to any deviation from the shape of a circle. Specifically, the term "non-circular" also refers to a first part 30 that is circular in cross-section and has a projection perpendicular to its circumferential surface, for example, in the form of a pin.This engages in a corresponding recess in the second part 31 and thus prevents the first part 30 from rotating in the second part 31.

[0053] In contrast to Figure 2, in the valve upper part 4 of Figure 4, the first part 30 is detachably fixed in the second part 31 by means of a screw connection. For this purpose, the first part 30 has an external thread 47 that is at least partially horizontal and can engage in a corresponding horizontal internal thread 46 of the second part.

[0054] In summary, at least one embodiment of the present invention may have at least one of the following features and / or provide at least one of the following advantages:

[0055] - Easy removal of the drain cup or the first part of the valve top.
