Description

[0001] The invention relates to a sanitary basin, in particular a sink, with a basin bottom, with at least one basin wall running substantially vertically or steeply relative to the basin bottom, with a drain opening provided with a drain valve, and with an overflow.

[0002] Sanitary basins such as washbasins and sinks come in a wide variety of designs. Such basins are typically made of stainless steel, plastic, ceramic, or composite material.

[0003] In conventional wash basins and sinks, the drain and overflow are in direct view. Soiling, such as food scraps, and deposits, such as dirt pockets, are immediately visible and unsightly at the drain or overflow. The drain and overflow of conventional wash basins and sinks are generally difficult or difficult to keep clean. Another problem with conventional wash basins and sinks is that their drain valve can be disrupted by objects, such as dishes, placed over them. Such a malfunction of the drain valve results in slow or even no water draining from the wash basin or sink. Another unsatisfactory problem with conventional wash basins and sinks is that the position of the drain valve is not visible when the basin is filled with dishes or cloudy dirty water.Furthermore, conventional washbasins and sinks have at least two separate openings for the drain and overflow of water entering the basin, which open in different directions or are widely spaced apart, usually in the basin floor and in a side wall or a side draining area of ​​the basin. This results in a complex piping system that takes up a relatively large amount of space below the basin.

[0004] Based on this, the invention is based on the object of improving a sanitary basin, in particular a wash basin or sink, of the type mentioned at the outset, with regard to its function and appearance by reducing or eliminating one or more of the problems identified above in the prior art.

[0005] This object is achieved by a sanitary basin having the features specified in claim 1. Advantageous embodiments of the inventive solution are the subject of the subclaims referring back to claim 1.

[0006] The sanitary basin according to the invention, in particular a wash basin or sink, is characterized in that the drain opening or the drain opening and the overflow are arranged concealed behind at least one cover which is detachably connected to the substantially vertical or steep basin wall.

[0007] This ensures that at least the drain and any dirt attached to it are not in the direct field of vision of the basin. Furthermore, the solution according to the invention does not impede the function of the drain valve by objects placed on the basin floor (e.g. dishes). As will be explained in more detail below, the solution according to the invention makes it possible for the respective functional position of the drain valve to be visible even when the basin is filled with dishes or cloudy dirty water. Preferably, the drain opening and the overflow are arranged together and concealed behind at least one cover that is detachably connected to the basin wall. This makes it possible to reduce the complex piping between the drain and overflow outside and in particular below the basin, thus creating usable space for arranging furniture or storing objects.

[0008] Preferably, neither the drain opening nor the overflow opening are located in the actual working area of ​​the basin according to the invention. Since the cover is detachably connected to the essentially vertical or steep basin wall, the basin according to the invention allows for easy cleaning and maintenance of the drainage system and the overflow.

[0009] The preferred embodiment of the invention, in which the drain opening and the overflow are arranged together and concealed behind the at least one cover, enables in particular simplified assembly of the drain valve together with the overflow. For this purpose, the drain valve and the overflow are arranged or mounted, for example, on a common drain housing. In this case, by mounting the common drain housing on the sanitary basin, the drain valve and the overflow can be connected to the sanitary basin at the same time. This saves assembly time. The basin according to the invention can have a common floor through-opening for the drain and the overflow, to which the drain housing can be or is mounted. The common drain housing for the drain and the overflow can also be referred to as a central connection or common connection.

[0010] The drain housing of the sanitary basin according to the invention preferably has a lateral outlet opening to which a drain pipe can be connected. The lateral outlet opening of the drain housing can, for example, be designed in the form of a connection piece. This design contributes to compact, space-saving drain piping below the basin.

[0011] A further embodiment of the invention is characterized in that the basin wall has a niche in which the drain opening or the drain opening and the overflow are arranged. This embodiment makes it possible to realize a concealed arrangement, in particular of the drain opening, in a compact design and with minimal additional material wall for covering the drain opening. In particular, this embodiment makes it possible to design the inner surface of the sanitary basin as a substantially closed inner surface.

[0012] According to a further embodiment of the invention, guides for the form-fitting connection of the cover are formed or attached on and / or in the recess. This design enables simple installation as well as precise and reliable positioning of the cover on the essentially vertical or steep pool wall.

[0013] The guides can, for example, be in the form of parallel ribs that extend vertically or almost vertically along opposite, narrow sides of the niche. According to an alternative embodiment, the guides can also be designed in the form of parallel columnar guide elements or in the form of vertical, parallel guide pins, wherein these guide elements or guide pins are arranged separately and at a distance from the wall of the niche. For example, these columnar guide elements or guide pins can be connected to the section of the basin floor located in the niche. According to a further or alternative embodiment of the invention, the guides assigned to the cover are part of a drain housing having the drain valve and / or the overflow.

[0014] According to a further embodiment of the invention, the basin wall containing the niche is a front, rear, right, or left basin wall of the sanitary basin. The variants specified here are characterized by various advantages. If the basin wall containing the niche is the front basin wall of the sanitary basin, the cover attached to the niche is hardly noticeable or only slightly noticeable when viewed from the basin. Furthermore, this variant is advantageous if, according to a further embodiment of the invention, the cover is movably, preferably displaceably, mounted on the basin wall, and the drain valve can be operated using the movably mounted cover. In this case, the cover is located in the immediate vicinity of the front edge of the basin when the sanitary basin is installed, and is therefore very easy to reach and operate for the user of the basin.With regard to the basin according to the invention, a front basin wall is understood to mean, for example, a basin wall of the basin which is located further away from an assembly opening of the basin used for the assembly of a water inlet fitting than a rear basin wall of the basin which is located near or closer to this assembly opening.

[0015] The variants in which the niche wall is the rear, right, or left wall of the sanitary basin allow for a comparatively significant reduction in the wastewater piping below the basin that needs to be connected to the basin's drain valve. This allows for optimized usable space or storage space for objects or furniture below the sanitary basin.

[0016] In the four niche designs mentioned above, the drain opening and / or the drain housing are preferably elongated, for example, oval. This allows the depth of the niche to be kept small for a given drain opening size or drainage capacity, thus saving space that can be used as installation space or storage space if necessary.

[0017] A further embodiment of the invention provides that the niche in which the drain opening or the drain opening and overflow are arranged is formed in a front or rear wall corner of the sanitary basin, wherein the cover, viewed horizontally in the assembled state, preferably has a concavely curved inner surface. This also makes it possible to keep the depth of the niche small for a given drain opening size or given drainage capacity, thus saving space that can be used as installation space or storage space if necessary. With this design of the niche, the drain opening can preferably be essentially circular. A circular drain opening can be closed particularly reliably in a liquid-tight manner using an appropriately designed drain valve.

[0018] As already noted above, a preferred embodiment of the invention provides for the at least one cover to be movably, preferably displaceably, mounted on the pool wall. This allows for convenient access to the drain valve, particularly for cleaning and maintenance. For this purpose, the movably mounted cover can, for example, be moved into a maintenance position, preferably pushed up, and returned to a functional or operating position after maintenance of the drain valve.

[0019] As also noted above, a further embodiment of the invention provides that the drain valve can be actuated by means of the movably mounted cover. This expansion of the cover's functional scope contributes to a simple design and easy cleaning of the sanitary basin. Preferably, the cover is associated with a reset mechanism that automatically moves the cover to a raised position relative to the basin floor after the drain valve has been confirmed closed by the cover, creating a drainage gap between the cover and the basin floor.

[0020] According to a further embodiment, the drain valve is designed such that it automatically assumes an open position when the cover is removed from the basin according to the invention. Thus, when the cover is removed, the drain valve remains in the open position.

[0021] A further embodiment of the invention provides that the pool wall has a counter-bearing with a locking clamping mechanism supported thereon, wherein the cover has a driver that tensions the locking clamping mechanism upon downward displacement of the cover, wherein the locking clamping mechanism performs its locking function in a specific position of the driver. This allows for a reliable and convenient operating function of the cover.

[0022] A further embodiment of the invention is characterized in that the at least one cover is provided with an actuating mechanism that has an actuating element and is designed such that the drain valve can be actuated by pressing or turning the actuating element. This allows a reliable and convenient actuation function for the drain valve to be realized on the cover.

[0023] With regard to a simple, reliable and comfortable operation of the drain valve, a further embodiment of the invention provides that the drain valve is designed as a spring-loaded valve and / or is provided with a locking tension mechanism.

[0024] A further advantageous embodiment of the invention provides that a drain housing provided with an overflow is attached to the drain opening, wherein the overflow is designed in the form of an overflow pipe projecting upwards directly from the top side of the drain housing. This allows the drain and overflow technology of the sanitary basin according to the invention to be implemented in a particularly space-saving manner. The overflow pipe is preferably connected to the drain housing via a detachable connection, for example a plug-in connection or screw connection. The latter embodiment is advantageous from a manufacturing point of view. Furthermore, this embodiment facilitates cleaning of the overflow and the drain. The upper end of the overflow pipe ends at a vertical distance from the top side of the basin or from the underside of a horizontal web of the cover.Furthermore, the detachable connection of the overflow pipe to the drain body allows for easy replacement of the overflow pipe with another, shorter overflow pipe that thus defines a lower overflow level. The overflow level of the overflow can thus be easily varied. For example, the overflow pipe detachably connected to the drain body can be omitted if necessary or replaced with a shorter or lower overflow pipe. For example, the drain body can have a connecting piece formed or arranged on its upper side for detachably connecting the overflow pipe, whereby this connecting piece itself defines a shorter or lower overflow pipe if the detachably connected, preferably longer, overflow pipe is removed if necessary.

[0025] In this context, a further embodiment of the invention provides for the drain valve to be mounted, preferably removably mounted, in the drain housing. This embodiment allows for the drain housing and the drain valve to be mounted together. If the drain valve is removably mounted in the drain housing, this facilitates cleaning of the drain housing and any connected wastewater pipe.

[0026] According to a further advantageous embodiment of the invention, the overflow, which is preferably designed in the form of an overflow pipe projecting upwards directly from the top of the drain housing, is horizontally spaced from the drain valve. In other words, in this embodiment, the drain in the form of the drain valve and the overflow are positioned independently of one another next to each other on the drain housing.

[0027] According to a further advantageous embodiment, the basin wall and the at least one cover, when mounted on the basin wall, are designed to be substantially flush with each other horizontally on the inside. This allows for a visually closed sanitary basin, in particular a sink, without any abutting edges on the inside of the basin wall.

[0028] A further embodiment of the invention provides that the cover has on its upper side an optical display and / or at least one electronic

[0029] Operating element for controlling at least one valve function. This configuration advantageously expands the range of functions of the cover. By means of the electronic operating element or a corresponding control panel on the top of the cover, for example, control (actuation) of an electromotive or electromagnetic drain valve can be enabled. Alternatively or additionally, the electronic operating element or the control panel can enable control (actuation) of an electromotive or electromagnetic water inlet valve. In particular, the control assigned to the drain valve can be designed to set different opening states of the drain valve or different drain volume flows. The control of the water inlet valve can also comprise temperature control and / or quantity control, in particular volume flow control, of the inflowing water (drinking water).The control of the drain valve can be linked to the control of the water inlet valve, for example, using a shared automatic or intelligent control system. The set water temperature and / or a set water inlet volume and / or a set water inlet flow rate and / or a set opening state of the drain valve or drain flow rate can be displayed by the visual indicator on the top of the cover.

[0030] Furthermore, the invention allows for individual design adaptations, for example by making the cover from a different material and / or with a different material color than the sanitary basin.

[0031] The invention is explained in more detail below with reference to several exemplary embodiments. The drawings show schematically: Fig. 1 shows a sanitary basin according to the invention inserted into a worktop with an optional water inlet fitting, in a perspective front view; Fig. 2 shows the sanitary basin according to Fig. 1 without worktop and without water inlet fitting in a perspective rear view, with a view of a vertically movable cover inserted in a niche of the front basin wall; Fig. 3 a section of the sanitary basin according to Fig. 2 , showing a vertical section in the area of ​​the concealed drain valve; Fig. 4 a section of the sanitary basin according to Fig. 1 with worktop, showing a vertical section in the area of ​​the concealed overflow; Fig. 5 the sanitary basin according to Fig. 1 in another perspective rear view, similar to the Fig. 2 , but here the sliding cover inserted in the niche of the front basin wall is lowered; Fig. 6 the sanitary basin according to Fig. 1in another perspective rear view, as in Fig. 5 , but here the sliding cover is pushed up into a maintenance position; Fig. 7 and 8 the sanitary basin according to Fig. 1 in another perspective rear view, similar to the Figures 2 and 6 , but here the sliding cover is removed; Fig. 9 a detailed view of the niche formed in the front side wall without cover; Fig. 10 a perspective bottom view of the sanitary basin according to Fig. 5 with connected drain pipe system; Fig. 11the sanitary basin according to Fig. 2 in a top view; Fig. 12 a detailed view of the top of the cover inserted in the niche; Fig. 13 another example of a sanitary basin according to the invention inserted into a worktop with optional water inlet fitting, in a perspective front view; Fig. 14 the sanitary basin according to Fig. 13without water inlet fitting in plan view; Fig. 15 a section of the sanitary basin according to Fig. 13 without worktop, showing a vertical section in the area of ​​the concealed drain valve; Fig. 16 a section of the sanitary basin according to Fig. 13 without worktop, showing a vertical section in the area of ​​the concealed overflow; Fig. 17 the sanitary basin according to Fig. 13 without worktop and without water inlet fitting in a perspective rear view, with a view of a vertically movable cover inserted in a corner niche of the basin wall, on which a mechanical control element for operating the drain valve is held; Fig. 18 the sanitary basin according to Fig. 17 , with the control element in a lowered position; Fig. 19the sanitary basin according to Fig. 17with a view of the corner niche, with the cover moved upwards or removed for maintenance purposes; Fig. 20 the sanitary basin according to Fig. 19 without cover in a plan view; and Fig. 21 the sanitary basin according to Fig. 20 in a perspective bottom view.

[0032] The sanitary basin 1 according to the invention shown in the drawing is intended as a sink, particularly for kitchens. However, the basin (sink) 1 can also be used for other purposes, for example, in a washroom or laboratory. The basin 1 optionally has a lateral extension 1.1 on the top, which serves as a draining board. The extension (draining board) 1.1 can be bowl-shaped or basin-shaped and have a slope toward the basin 1 as the main basin.

[0033] The basin 1 is preferably made of plastic, ceramic, or composite material, for example, by means of a casting process. It can have a relatively thick wall thickness, e.g., in the range of 6 to 20 mm. Alternatively, such a basin can also be made of comparatively thin sheet steel by means of a forming process, in particular a deep-drawing process.

[0034] Fig. 1 shows a section of a room wall or partition wall 3, to which a worktop 5, for example a kitchen worktop, is mounted. The worktop 5 has a cutout into which a sanitary basin 1 according to the invention is inserted.

[0035] The basin 1 has a laterally projecting, circumferential collar 1.2 on the top, which optionally encloses the extension 1.1 serving as a draining board. The basin 1 rests with the collar 1.2 on the edge of the worktop surrounding the cutout in the worktop 5. The collar 1.2 or the extension 1.1 can have a through-opening 1.3 to which an optional water inlet fitting 6 is or can be mounted. The water inlet fitting 6 is preferably provided with an electronically controllable inlet valve. In particular, the water inlet fitting 6 can have a proximity sensor 6.1 that reacts to approach, i.e., without direct contact, without contact.

[0036] The sanitary basin 1 has a basin bottom 1.4, a basin wall 1.5 that runs essentially vertically or steeply relative to the basin bottom 1.4, a drain opening 1.9 that is provided with a drain valve 2, and an overflow 4. According to the invention, the drain opening 1.9 and the overflow 4 are concealed behind a cover 8 that is detachably connected to the basin wall 1.5. For this purpose, the basin wall 1.5 has a niche 9 in which the drain opening 1.9 and the overflow 4 are arranged together. The cover 8 is, for example, plate-shaped and has an angled plate area or web 8.1 on the upper side. The cover 8 can be made, for example, from plastic material, ceramic material, composite material, or stainless sheet metal. The cover 8 preferably has a completely closed visible surface 8.2 without a through hole. However, it is also within the scope of the invention for the angled web 8 to have a1 or plate area a through opening (not shown) is formed.

[0037] The cover 8 is guided for vertical displacement, for example, by the basin or niche geometry. For this purpose, parallel guides 10 are preferably formed or secured in the niche 9, to which the cover 8 is or can be connected in a form-fitting manner. The guides 10 can, for example, be implemented in the form of parallel ribs that extend vertically or almost vertically along the opposing narrow niche sides 9.1, 9.2. On its vertically or steeply extending edges 8.4, 8.5, the cover 8 has elements that engage around the guides 10 in a form-fitting manner with slight play, for example, flanges with grooves associated with the ribs (guides 10).

[0038] The drain opening 1.9 of the basin 1 according to the invention is formed in a part 1.41 of the basin base 1.4, wherein this part 1.41 of the basin base 1.4 extends into the recess 9. In a normal position of the cover 8 inserted into the recess 9, in which the upper side 8.10 of the cover 8 is substantially flush with the upper side of the collar 1.2 of the basin 1, the drain opening 1.9 formed in the basin base 1.4 is not directly visible. Rather, only the completely closed section 1.42 of the basin base 1.4, located in front of the cover 8, is visible from above.

[0039] The cover 8 and the guides 10 assigned to it and arranged in the niche 9 are designed such that the pool wall 1.5 and the cover 8, when viewed horizontally in the assembled state, are essentially flush with one another on the inside (cf. Figures 2 and 5 ).

[0040] The drain opening 1.9 is in the Figures 1 to 10 In the illustrated embodiment, the drain opening 1.9 is preferably elongated, for example, as an oval hole or slot. The longitudinal axis of the elongated drain opening 1.9 runs parallel to that of the basin wall 1.5 or the rear wall 9.5 of the niche 9. The drain opening 1.9 also serves as the overflow 4, i.e., the drain opening 1.9 is a common through-opening (opening) for the drain 11 and the overflow 4.

[0041] On the underside of the basin floor 1.4, in the area of ​​the drain opening 1.9, a drain housing 12 is arranged, which surrounds the drain opening 1.9 in a watertight manner. The drain housing 12 defines a common connection for the drain 11 and the overflow 4. The drain housing 12 is elongated, for example, channel-shaped, corresponding to the drain opening 1.9. Directly on the top side of the drain housing 12, the overflow 4 is designed in the form of an upwardly projecting overflow pipe (see Fig. 4 and Fig. 7 ). The overflow pipe 4 is connected to the drain housing 12 via a detachable connection, preferably a plug connection or screw connection (see Fig. 8 ). The upper end of the mounted overflow pipe 4 ends at a vertical distance from the horizontal web 8.1 of the cover 8.

[0042] In the Figures 6 to 10It can be seen that the drain housing 12 has a connecting piece 4.1 formed or arranged on its upper side for the detachable connection of the overflow pipe 4. This connecting piece 4.1 itself defines a shorter or lower overflow pipe when the preferably longer overflow pipe 4, which can be detachably connected to it, is removed as needed. Thus, two different overflow levels can be variably adjusted as needed.

[0043] In the drain housing 12, next to the overflow 4, the drain valve 2 is mounted. The drain valve 2 is designed as a spring-loaded valve and is provided with a locking mechanism 13. It has a dirt trap 20 on the top. The drain valve 2 is actuated by means of the vertically movable cover 8. The locking mechanism (also called click-clack mechanism) enables two operating positions (functional positions), namely a (first) operating position in which the drain valve 2 is opened and the cover 8 is in the Fig. 2 shown position with the basin bottom 1.4 defines an inlet gap 15; and a (second) operating position in which the drain valve 2 is closed and the cover 8 is in the position shown in Fig. 5 shown lowered position rests essentially gap-free on the pelvic floor 1.4.

[0044] Alternatively, a reset mechanism is assigned to the cover, which automatically moves the cover 8 into a raised position relative to the basin floor 1.4 after the drain valve 2 has been closed, which is performed by the cover 8, so that a drainage gap is created between the cover 8 and the basin floor 1.4. The reset mechanism can be integrated into the locking clamping mechanism (click-clack mechanism).

[0045] Furthermore, the basin wall 1.5 in the niche 9 has a counter bearing 9.7 on which the above-mentioned locking clamping mechanism 13 or an additional locking clamping mechanism is supported (see Figures 3 and 7). In this case, the cover 8 has a driver which, when the cover is displaced downwards, tensions the locking clamping mechanism 13 supported on the counter bearing 9.7. The locking clamping mechanism 13 performs its locking function in a specific position of the driver. The driver can be the angled web 8.1 or the plate area of ​​the plate-shaped cover 8 (cf. Fig. 3 ).

[0046] For cleaning or maintenance purposes, the cover 8 can be pushed or pulled up into a maintenance position and removed if necessary (see Figures 6 to 9 ). The drain valve 2, including the dirt trap 20, can then be removed from the drain housing 12 via the recess 9.

[0047] In the illustrated embodiment, the cover 8 and the niche 9 are positioned or formed on or in the front basin wall 1.5 of the sanitary basin 1. Alternatively, the cover 8 or the niche 9 can also be positioned or formed on or in the rear basin wall 1.6 or the right basin wall 1.7 or the left basin wall 1.8 (see. Fig. 11 ). Depending on the arrangement of the cover 8 and / or the niche 9, the sanitary basin 1 according to the invention, in comparison to conventional sinks in which the drain is directly visible in the basin floor and the overflow is arranged in a vertical or steep basin wall and / or in the draining board, can achieve a considerable reduction in the space required by the waste water pipe 30 to be mounted outside the basin 1 (cf. Figures 10 and 11 ).

[0048] As in the Figures 11 and 12As shown, a further optional embodiment of the invention consists in that the cover 8 has on its upper side an optical display 40, e.g. a light-emitting diode or liquid crystal display, and / or at least one electronic operating element 42, e.g. a control panel, for controlling at least one valve function. By means of the electronic operating element 42 or control panel, a water inlet fitting 6 and / or an electromotive / electromagnetically actuated drain valve can be controlled, including an adjustment of the temperature of the incoming water and / or an adjustment of a volume and / or volume flow of the incoming water. The values ​​of the set parameters can be shown by the optical display 40.

[0049] In the Figures 13 to 21Further embodiments of the invention are shown. As shown there, the invention also encompasses embodiments in which the niche 9' is formed in a front wall corner, for example, the left front wall corner 1.50 of the sanitary basin 1' (cf. Figures 14 and 20 ). Alternatively, the niche 9' can be formed in the front right wall corner 1.70, the rear left wall corner 1.60 or the rear right wall corner 1.80 of the sanitary basin 1'. The cover 8' has, viewed horizontally in the assembled state, a concavely curved inner surface 8.2'. The radius of curvature of the inner surface 8.2' of the cover 8' is considerably larger than the radius of curvature of the inner surface of the other wall corners 1.60, 1.70, 1.80 of the basin 1 (cf. in particular Figures 14 and 17 to 20 ).

[0050] Furthermore, in the Figures 13 to 19It can be seen that the invention also encompasses embodiments in which the cover 8' is provided with an actuating mechanism having an actuating element 85 and designed such that the drain valve 2' can be actuated by pressing or rotating the actuating element 85. The actuating element 85 can for this purpose be designed, for example, as a pressure rod or torsion rod which is displaceably or rotatably mounted on a top-side through-opening 82 of the cover 8' and is operatively connected by its lower end to the drain valve 2'. The actuating element 85 is connected to the cover 8', e.g. to its top-side horizontal web 8.1', in such a way that it remains captively held on the cover 8' when the cover 8' is moved upwards or when the cover 8' is removed from the niche 9'. The actuating element 85 can have an actuating head 85 which is larger in diameter than the rod 85.1.2, while the through opening 82 of the cover 8' has a stepped inner diameter (cf. . Fig. 15 ). Below the through-opening 82, the actuating element 85 can be secured against falling out of the through-opening 82 by a securing element (not shown) attached to the rod 85.1, for example a securing ring which engages in a groove (not shown) formed on the rod 85.1.

[0051] The cover 8' is in the Figures 17 to 19In the embodiment shown, the guide pins (guide bolts) 10' are held in position by guides 10' in the form of guide pins 10'. The guide pins (guide bolts) 10' are preferably manufactured separately and then connected to the section 1.41' of the basin base 1.4' located in the niche 9'. For this purpose, holes, preferably bores, e.g. threaded holes, are made in this section 1.41' of the basin base 1.4', into which the guide pins 10' are inserted or screwed in a watertight manner. These guide pins 10' are thus arranged separately and at a distance from the wall of the niche 9'. The cover 8' has form-locking elements assigned to the guide pins 10', which engage around the guide pins 10' when the cover 8' is in the assembled state. These form-locking elements of the cover 8' can, for example, be vertical bores in the wall of the cover 8'.

[0052] The cover 8' and the guide pins 10' assigned to it and arranged in the niche 9' are designed and arranged in such a way that the pool wall 1.5, 1.7 and the cover 8', when viewed horizontally in the assembled state, are essentially flush with one another on the inside (cf. Figures 14 , 17 and 18 ).

[0053] The section 1.41' of the basin base 1.4' located in the niche 9' has two separate through holes (openings) 1.91', 1.92', one of which (1.91') is assigned to the drain valve 2' and the other (1.92') to the overflow 4', whereby the overflow 4' is in turn designed in the form of an overflow pipe projecting upwards directly from the upper side of the drain housing 12'. The overflow pipe 4' is angled to adapt it to the geometry of the niche space and the space available there. The overflow pipe 4' can be permanently connected to the basin base 1.4'. The upper end of the overflow pipe 4' ends at a vertical distance from the horizontal web 8.1' of the cover 8'. The drain valve 2' arranged in the niche 9' next to the overflow pipe 4' is provided with a locking mechanism (so-called click-clack mechanism) which can be actuated by means of the actuating element 85 to close or open the drain valve 2'.The locking mechanism is integrated into the drain valve 2'. Although the drain valve 2' and the overflow 4' are arranged in separate through holes 1.91', 1.92', they are assigned a common pot-shaped drain body (drain housing 12'), which is connected, preferably detachably, to the basin 1' on the underside of the basin base 1.4', covering the through holes 1.91', 1.92'.

[0054] In the Figures 13 to 18 In the embodiments shown, the position of the drain valve 2', ie its functional state, can be determined from the position of the actuating element 85. If the actuating head 85.2 of the actuating element 85 protrudes above the top of the cover 8', as is particularly the case in the Figures 15 to 17shown, this means that the drain valve 2' is open, or in other words, is in its open position. On the other hand, if the actuating head 85.2 is substantially flush with the top of the cover 8', as shown in Fig. 18 is shown, this means that the drain valve 2' is closed, or in other words, is in its closed position.

[0055] The embodiment of the invention is not limited to the exemplary embodiments shown in the drawings. For example, the sanitary basin 1, 1' according to the invention can also have a different shape, for example, as a round sink with a circular or oval basin wall.
