Sink with tub and separate and movable insert plate resting on support wings of a lifting device

Description

[0001] One aspect of the invention relates to a sink with a tub. The tub has a bottom wall and adjoining side walls. The tub has a receiving space defined by the walls. Furthermore, the sink has an insert plate that is separate from the tub and inserted into the receiving space. The sink also has a lifting device with which the insert plate can be moved relative to the tub, wherein the lifting device has at least one lifting unit.

[0002] Such a sink is known, for example, from CN 109695275 A. This is designed as a vegetable washing basin with an automatic lifting device controlled by a switch.

[0003] US 2005 / 0067747 A1 discloses a sink comprising a tub. A base extending upwards is formed integrally with the tub bottom and is attached to the tub base. A plate can be attached to this base. This creates a cutting board on which objects, such as food, can be cut. This design is disadvantageous in that the integrated base is always present, resulting in a complex design for the tub and restricting the storage space. Furthermore, the plate that can be attached to the base is always positioned at a single height. It can only be attached or removed by a user.

[0004] Furthermore, a sink is known from DE 362 1151 A1. Separate from the tub, various inserts are provided that can be inserted into the receiving space. The inserts can be plates or other tub-like containers. These can be placed on the upper edge of the tub. This also severely limits the usability of a sink, and the inserts must be attached or removed by the user and can only be positioned in one specific position.

[0005] It is an object of the present invention to provide a sink with a tub and a separate insert plate, in which the insert plate is used multifunctionally.

[0006] This object is achieved by a sink according to claim 1.

[0007] One aspect of the invention relates to a sink with a tub. The tub has a bottom wall and adjoining side walls. The tub furthermore has a receiving space which is delimited by the bottom wall and the side walls. The receiving space is open at the top. The sink has an insert unit which is separate from the tub, in particular an insert plate, in particular a continuous and hole-free insert plate. This can be inserted or inserted into the receiving space. The sink furthermore has a lifting device with which the insert plate can be moved in the vertical direction of the sink relative to the tub. This is made possible by a specific lifting device of the sink. A sink is therefore now provided which fundamentally makes it possible to arrange the insert unit at different heights.This is also made possible by a lifting device, eliminating the need for manual adjustment by the user. The lifting device essentially allows for continuous height adjustment of the insert plate. This allows the insert plate to be moved to and adjusted to a wide range of heights.

[0008] The lifting device has at least one lifting unit. In addition, the lifting device has at least two support wings. The insert plate is placed on these support wings. The support wings are arranged at an upper end of the lifting unit and, viewed in a horizontal plane, are designed to protrude laterally beyond the dimensions of the lifting unit. By designing a lifting device in this way, a central unit, namely the lifting unit, can be formed in itself. Its dimensions and position can therefore be individually designed. As a result, the accommodation space is not disproportionately restricted by a lifting unit designed in this way. By being smaller in these horizontal dimensions than the two support wings, it can be designed to save space in this regard.However, since the insert plate is significantly larger than the lifting unit in this horizontal plane, it is particularly advantageous to create a correspondingly sufficient mechanical support structure here. This has been achieved with the support wings. This also allows the insert plate to be held mechanically stable. The direct contact of the insert plate is therefore not via the lifting unit, but via the support wings. The support wings therefore create a very advantageous support structure. In this context, the support wings can be made very shape-specific yet still delicate. This also allows the support wings to be made lighter. Since the support wings, like the insert plate, have to be lifted with the lifting unit, this type of specific design of the support wings is advantageous because they represent a relatively low additional weight to the insert plate.

[0009] The lifting unit is provided with an upper lifting segment in the vertical direction. At least one support wing is arranged on this upper lifting segment. This enables a mechanically stable connection of the support wings to the lifting unit. At least one of the at least two support wings is arranged on the lifting segment so that it can be moved relative to the lifting unit. This is a very advantageous design because it allows the position of the support wing to be adjusted on its own. This means that a support wing can be adjusted independently of the lifting unit itself. This is advantageous for setting an exact horizontal position for the support wings. This is advantageous in that it enables the insert plate to be stored horizontally. Since this is made possible by the support wings, the entire additional lifting unit does not have to be aligned accordingly. However, this can also be possible.

[0010] Furthermore, this design also advantageously allows the support wing to be deliberately adjusted relative to the lifting unit. This is particularly advantageous when the insert plate needs to be tilted from a horizontal position. In this case, only the support wing needs to be tilted, not the entire lifting unit.

[0011] In an advantageous embodiment, at least one of the at least two support wings is mounted on the lifting segment so that it can pivot about a horizontal axis. This advantageously enables a very simple yet precise pivoting position of the support wings relative to the horizontal plane. A specific tilting position of the insert plate can then be achieved particularly advantageously.

[0012] In an advantageous embodiment, at least one of the at least two support wings is V-shaped. This is a particularly advantageous geometric shape. On the one hand, the support wing thus projects relatively far beyond the lifting unit in a plane perpendicular to the height direction. This enables a particularly far-projecting mechanical coupling with the larger insert plate. This makes it particularly advantageous to prevent undesirable inclined positions of the insert plate. On the other hand, this V-shaped design creates a relatively delicate support wing. Such a V-shaped bracket thus has two V-legs oriented at an angle. In particular, these legs are straight.Preferably, the angular position of these V-shaped legs is such that one leg is oriented toward a first corner region of the insert plate, and the second V-shaped leg is oriented toward the adjacent second corner region of the angular insert plate. Particularly when the insert plate is square, a corresponding support structure can be formed with two support wings, which then preferably have four such V-shaped legs. This support structure is then star-shaped, particularly when viewed as a whole. In particular, it is X-shaped.

[0013] In particular, these V-shaped legs are oriented so as to project freely in a horizontal plane. Preferably, the two support wings are designed as separate components, and each of these two support wings is movably mounted on an upper lifting segment. In particular, they can each be pivoted individually and independently of one another via two parallel horizontal axes.

[0014] In an advantageous embodiment, the insert plate is attached directly to the support wings via a non-destructively detachable connection. This is another very advantageous design. On the one hand, the insert plate can be securely stored on these support wings. On the other hand, it can be removed reversibly. This allows the insert plate to be cleaned on its own, for example. Access to the support wings located underneath, as well as the entire lifting device, is also easier when the insert plate is removed. This is advantageous for cleaning purposes. But it is also particularly advantageous for assembly and maintenance work.

[0015] The connection may be mechanical. For example, this connection may be a plug-in connection.

[0016] In addition to or instead of this, this connection can be provided as a magnetic connection. Likewise, in addition to or instead of this, a snap connection can be provided.

[0017] In an advantageous embodiment, a recessed geometry is formed on the underside of the insert plate. This recessed geometry is particularly complementary to the geometry of the two support wings. Thus, the insert plate can be applied to the support wings from above, and these support wings then dip into the recessed geometry on the underside of the insert plate. This also enables an advantageous mechanical coupling. Appropriate additional plug-in elements can be provided in these recesses and / or the support wings. Magnets can also be provided.

[0018] Preferably, the insert plate is designed in a pyramid-like or conical shape on its underside. This is a further very advantageous design. This is because it allows medium, in particular liquid medium, which passes via the top side through the edge region of the insert plate to the underside to be drained away in a targeted manner. Such an uneven geometry allows the directing of liquid media on the underside to be carried out in a particularly advantageous manner. This means that a defined point can be formed on the underside from which this liquid medium then drips down into the tub. This allows a targeted drainage of medium, in particular liquid medium, from the underside to a specific point. This can then take place, for example, in the area above a drain opening formed in a bottom wall of the tub.This allows the medium running off the insert plate, especially the medium running off its underside, to drip or run directly into the drain opening.

[0019] In an advantageous embodiment, in addition to or instead of this, the insert plate can be provided with an air vent structure. The air vent structure is designed to divert air that has formed beneath the insert plate towards the edge of the insert plate. This is advantageous when the insert plate is moved downwards in the tub and thus the air present beneath the insert plate must be specifically discharged so that no corresponding air buildup or pressure buildup occurs between the insert plate and the bottom wall of the tub. Such a defined air vent structure enables this air discharge to be carried out in a particularly advantageous and directed manner.

[0020] Preferably, the lifting device is provided with an adjusting unit. With this adjusting unit, the support wings can be adjusted in a horizontal position in a common horizontal plane. This is particularly advantageous in order to be able to position the insert plate then positioned thereon in an exactly horizontal position. In addition to or instead of this, it can be provided that the adjusting unit can be used to set a horizontal position of the support wings in which an upper side of the insert plate is flush with an upper side of a visible component of the sink surrounding the insert plate at the edge. Such a visible component can be, for example, a decorative frame or a mounting frame or an upper edge of the tub. This prevents undesired tipping relative to this visible component at the edge.

[0021] Preferably, the support wings extend up to one-third of the surface of the insert plate with respect to a plane perpendicular to the vertical direction. This achieves the aforementioned advantages of a support structure that is as stable as possible, which particularly advantageously prevents undesired tilting of the insert plate.

[0022] Preferably, the upper lifting segment has an upwardly raised central web on one upper side. The two support wings are advantageously pivotally mounted on this central web on opposite web sides of this central web. This is a further advantage. On the one hand, this creates an upwardly projecting raised structure on which the support wings can be easily mounted, thus improving the mobility of the support wings. On the other hand, when the support wings are in the horizontal position, their upper side is flush with the central web. The support wing and the central web thus form a continuous support surface for the insert plate. This improves the large-area support of the insert plate in this central region.

[0023] Preferably, the center web is provided with upper side regions adjacent to the upper side, on which the support wings rest in the home position. This upper lifting segment also creates a more stable abutment for the support wings. The central, or inner, region of the support wings is thus stably supported from below.

[0024] It is preferably provided that the support wings of the at least two support wings are movable independently of one another relative to the lifting unit.

[0025] In an advantageous embodiment, a support wing can be formed in one piece. It can be made of plastic, for example. This reduces its weight and is resistant to wear from liquid or other media that may occur in such a tank. However, a support wing made of stainless steel can also be provided.

[0026] It can be provided that one leg of such a bracket, as explained above, is designed as a continuous plate strip. However, it can also be provided that such a leg is designed as a frame, which in this context is formed as a kind of skeletal arm and has a corresponding opening.

[0027] In particular, a plate holder for the insert plate is formed on the upper region of the upper lifting segment. For example, this plate holder can be realized as an injection-molded component, in particular as a 2K injection-molded component. It can be provided that there is at least one through-hole in this plate holder. An actuating element can extend through this hole from below, with which a support wing positioned on the plate holder can be lifted. In particular, this lifting can result in pivoting about a horizontal pivot axis, so that a support wing can be inclined and thus tilted. Preferably, such a hole or a passage in the plate holder is covered in the upper region by an elastic component. This can prevent media from entering this hole in the plate holder from above.Because this cover is elastic, the actuating element can act on this elastic element and bend it upwards. This allows a corresponding actuating force to be transferred to the support wing, tilting it.

[0028] In an advantageous embodiment, it is provided that an upper side of the insert plate has an area with respect to a depth direction and a width direction which amounts to at least 80 percent, in particular at least 90 percent, in particular at least 95 percent of the area of the receiving space in a horizontal plane. However, the area of the upper side of the insert plate is less than 99 percent of this area of the receiving space. Through such dimensioning, the insert plate is formed virtually over the entire surface with respect to the clear width of the receiving space between the side walls and thus fills this receiving space almost completely when viewed in the horizontal plane. On the other hand, however, a small gap is made possible all around, in particular between 3 mm and 15 mm, in particular between 3 mm and 10 mm, so that on the one hand the relative movement of the insert plate can take place unhindered during a position adjustment or a position change.In particular, this prevents direct contact and, if necessary, rubbing of a side edge of the insert plate against the inside of the side walls. This prevents damage to the side walls, as well as damage to the insert plate and the lifting device. Last but not least, this design also advantageously allows any liquid present on the upper side of the insert plate to drain easily into the receiving space through this gap between the edge of the insert plate and the inside of the side walls.

[0029] The tub preferably has a drain, especially on the bottom wall. This allows any medium that collects in the tub to drain away easily via the drain.

[0030] In particular, the tub is formed integrally with the bottom wall and the side walls. In particular, the tub is made of metal.

[0031] The base wall may be flat, slightly inclined, or slightly curved. In particular, the point on the base wall where an outlet for the sink drain is provided is set furthest down in height.

[0032] It can be provided that the upper side of the plate is completely flat. However, it can also have a slight curvature. It is also possible for the upper side of the insert plate to be structured at least in some areas. This can create a certain roughness. This can better prevent undesired slipping of objects applied to it. For example, this is advantageous if a change in position of the insert plate occurs while objects are still arranged on the upper side of the insert plate. It is also possible for the upper side to have specific positioning areas. These can be depressions. For example, such depressions can be relatively small. This is advantageous in order to be able to position vessels such as a glass or the like more securely. This is particularly advantageous if a change in position involves tilting and / or rotating.This prevents unwanted slippage of such containers. Furthermore, such predefined positioning areas ensure that, for example, when containers are placed on top of the insert plate and are to be filled via the faucet, the water flowing from the faucet flows directly into the containers during a rotational movement and does not bypass the containers and hit the insert plate.

[0033] The lifting device can comprise a lifting unit and a motor. The motor can move the lifting unit at least vertically.

[0034] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction" indicate the positions and orientations given when the sink is used and arranged as intended.

[0035] Embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: Fig. 1 a schematic sectional view through an embodiment of a sink according to the invention with an insert plate in a first position; Fig. 2 the representation of the sink according to Fig. 2 with the insert plate in a Fig. 1 different second position; Fig. 3 a plan view of an embodiment of a sink; Fig. 4 a perspective partial view of an embodiment of a sink with an embodiment of support wings of a lifting device; Fig. 5 a perspective partial view of another embodiment of a sink with an embodiment of support wings of a lifting device; Fig. 6 a perspective view of an insert plate looking from the underside.

[0036] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0037] In Fig. 1 A sink 1 is shown in a schematic vertical sectional view (xy plane with height direction y and width direction x). The sink 1 has a tub 2. The tub 2 has a bottom wall 3 and adjoining and upwardly extending side walls 4, 5, 6 ( Fig. 3 ) and 7 ( Fig. 3 ). The tub 2 is in particular formed in one piece. It is preferably made of metal. The tub 2 has a receiving space 8. The receiving space 8 is delimited by the aforementioned walls 3 to 7. The tub 2 thus has an upper loading opening 9. The sink 1 furthermore has an insert unit. The insert unit is in particular an insert plate 10. The insert plate 10 is in particular formed in one piece. The insert plate 10 is a separate component of the sink 1 from the tub 2. The sink 1 furthermore has a lifting device 11. The insert plate 10 is arranged on the lifting device 11. In particular, it is arranged on the lifting device 11 in a way that can be removed non-destructively. The insert plate 10 can be moved relative to the tub 2 by the lifting device 11. In this context, a movement in the vertical direction (y-direction) of the sink 1 can take place.Additionally or instead of this, rotation about a vertical axis A of the lifting device 11 can occur. Additionally or instead of this, tilting of the insert plate 10 can occur. This means that the insert plate 10 can be adjusted with its plane at an angle to a horizontal plane. It can thus be positioned tilted or inclined. In . Fig. 1 The insert plate 10 is shown in an exemplary position in the receiving space 8. In particular, this is a downwardly retracted position. In this respect, the insert plate 10 is arranged directly adjacent to the base wall 3.

[0038] Preferably, the sink 1 has an interaction unit 12. The interaction unit 12 can have a display unit 13 ( Fig. 3 ). The interaction unit 12 can have an operating device 14. The operating device 14 can have one or more operating elements. The operating elements can be push buttons or switches or toggle elements or rotary knobs. However, the operating device 14 can also have a touch-sensitive control panel 15 in addition to or instead of this. In an advantageous embodiment, it can be provided that the interaction unit 12 has at least one optical detection unit 16. The optical detection unit 16 can be a camera, for example. The camera can be sensitive in the spectral range visible to humans. However, the interaction unit 12 can also have an acoustic unit 17 in addition to or instead of this. This acoustic unit 17 can be designed to receive and / or output voice signals. In addition, the interaction unit 12 can have an identification unit 18.The identification unit 18 is designed to recognize or identify a user of the sink 1. The identification unit 18 can, for example, also be formed by the optical detection unit 16. In addition to or instead of this, the identification unit 18 can, however, also have, for example, the acoustic unit 17. This allows the user to be identified, for example, by evaluating a user's voice signal. In addition to or instead of this, the identification unit 18 can be designed as a unit for detecting and evaluating a biometric feature of a user. For example, this can be a fingerprint sensor or a sensor for recognizing an iris pattern.

[0039] As in the Fig. 1 bis 3 As can be seen, the interaction unit 12 can be formed laterally and directly adjacent to the tray 2. For example, an upwardly open receiving housing 19 can be provided here. The receiving housing 19 can be formed separately from the tray 2. However, it can also be formed non-destructively and permanently with the tray 2. In particular, the receiving housing 19 can also be formed integrally with the tray 2. The side wall directly adjoining the receiving housing 19, in this example the side wall 5, also forms a boundary wall for the receiving volume 20 of the receiving housing 19.

[0040] Thus, the receiving volume 20 is separated from the receiving space 8 of the tub.

[0041] In Fig. 2 the representation is in accordance with Fig. 1 shown, but the insert plate 10 in a Fig. 1 different positions. In Fig. 2 the insert plate 10 is oriented horizontally, but moved upwards. In particular, this position represents the maximum possible height in normal mode. In particular, in this position, an upper side 10a of the insert plate 10 is flush with an upper edge 2a of the tub 2. In particular, in this position the insert plate 10 forms a cover or lid for the receiving space 8. However, this upper edge 2a can also be, for example, an upper side of a mounting frame or a decorative frame that is a component of the sink 1. Using the mounting frame, the sink 1, in particular the tub 2, can be mounted in a recess in a worktop. Using a decorative frame, the tub 2 can be covered from above. A gap between the tub 2 and a boundary wall in the worktop, which boundary wall defines the recess, can thus be covered from above. Such a decorative frame represents, in particular, an upper visible component of the arrangement.

[0042] In particular, the sink 1 also has a control unit 21 ( Fig. 3 ). The control unit 21 can operate the lifting device 11. In particular, the interaction unit 12 can also be operated by the control unit 21.

[0043] The sink 1 can, as shown in the simplified plan view in Fig. 3 can be seen, preferably also have a faucet 22. The faucet 22 represents a functional unit of the sink 1. Likewise, the interaction unit 12, in particular the operating device 14, can be regarded as a functional unit of the sink 1. Another functional unit of the sink 1 can be the insert plate 10. Another functional unit of the sink 1 can be the lifting device 11.

[0044] The lifting device 11 preferably comprises a lifting unit and a motor. This allows its length or height to be adjusted along the vertical axis A. Furthermore, it can be rotated about the vertical axis A in addition to or instead of the vertical axis A. This also enables a rotational movement about this vertical axis A as a position or position change of the insert plate 10. Last but not least, the lifting device 11 can also be adjusted so that the insert plate 10 can be tilted or inclined relative to a horizontal plane.

[0045] The interaction unit 12 can detect an operating state of the sink 1 and / or a change in the operating state of the sink 1 and / or an operating action of a user who operates the sink 1, in particular at least one functional unit of the sink 1. Depending on the detection by the interaction unit 12, the lifting device 11 can be operated to automatically change the position of the insert plate 10. Fig. 3 Furthermore, a schematic representation of a user's finger 23 is shown. The interaction unit 12 is preferably designed to detect a gesture of the user, in particular of the finger 23. In particular, the gesture is a contactless gesture. In addition to or instead of this, however, the operating device 14 can also be operated directly with the finger 23. It is provided that an operating state and / or a change in the operating state can be detected by the camera 16 and / or the acoustic unit 17 and / or the operating device 14. An operating state can, for example, be a setting of the operating device 14 and / or a change in the operating state can be a change in the setting of the operating device 14.

[0046] A change in position of the insert plate 10 can be dependent on the type and / or intensity and / or duration of an operating state of at least one functional unit of the sink 1 and / or a change in position can be dependent on the type and / or intensity and / or duration of an operating state change of at least one such functional unit of the sink 1.

[0047] The interaction unit 12 has a normal mode. In this mode, the actual operation of the sink 1 is also recorded. In addition, the interaction unit 12 has a definition mode that differs from the normal mode. This can be set, for example, by a user. In this definition mode, it is possible for at least one user to define or specify at least one reference position of the insert plate 10. In particular, such a reference position in this definition mode can be linked to a specific operating state of at least one functional unit of the sink 1 and / or to a defined change in the operating state of at least one functional unit of the sink 1. At least one such reference position can be stored as a user profile in a memory unit 24 of the interaction unit 12.

[0048] In an advantageous embodiment it is provided that the Fig. 3 shown area (depth direction z and width direction x) of the upper side 10a at least 80 percent, in particular at least 90 percent, in particular at least 95 percent of the area of the receiving space 8, which in a horizontal plane (in Fig. 3 the plane of the figure). In particular, however, this area of the upper side 10a is smaller than 99 percent of this area of the receiving space 8 in the said horizontal plane. This ensures that a circumferential edge 25 of the insert plate 10 is spaced from the side walls 4, 5, 6 and 7. In particular, this creates a circumferential gap 26 between the insert plate 10 and the side walls 4 to 7. The gap 26 can be between 3 mm and 15 mm. Preferably, this gap 26 is so small, at least in the horizontal position of the insert plate 10, that objects such as cutlery or the like cannot slip through. Pinching of a finger 23 can then also be avoided in this horizontal position of the insert plate 10.

[0049] As in the Fig.1 bis 3 As further shown, the sink 1 has a drain opening 27, for example a drain. This is formed in particular in the bottom wall 3. Media from the receiving space 8 can drain out of the tub 2 through this drain opening 27.

[0050] In Fig. 4 A perspective view of an embodiment of a sink 1 is shown. The lifting device 11 is shown. The lifting device 11 has a lifting unit 28. This is fastened centrally to the base wall 3. The lifting unit 28 is movable in the direction of the axis A. The lifting unit 28 has several lifting segments. Fig. 4 the lifting unit 28 is shown in the fully retracted state. This means that it is retracted as far as it will go downwards into the receiving space 8. This lifting unit 28 preferably has an upper lifting segment 29. A plate holder 31 is arranged in an upper region 30 of this upper lifting segment 29. The plate holder 31 is here a flat-cylindrical disc. This plate holder 31 has a central web 32. A first support wing 33 is arranged on this central web 32. In particular, the support wing 33 is mounted on the central web 32 so as to be pivotable about a horizontal axis B. The one-piece support wing 33 rests from above on the plate holder 31. An upper side 34 of this plate holder 31 has upper side regions 34a and 34b. These are offset downwards relative to the central web 32. The support wing 33 rests on this upper side region 34a.For improved clarity, a second support wing is arranged, separate from the first support wing 33, but in particular of the same size and shape. This second support wing is pivotally mounted on the central web 32 about a further horizontal axis C. The horizontal axes B and C are oriented parallel to each other. The second support wing rests from above on the second upper side region 34b. In the horizontal basic position, an upper side 33a of the support wing 33 is flush with an upper side 32a of the central web 32. This is configured accordingly with an upper side of the second support wing.

[0051] The support wing 33 and the second support wing (not shown) are spaced apart from one another by the central web 32. They can be pivoted independently of one another about their axes B and C. This also allows individual tilt positions of a support wing 33 relative to the horizontal plane to be set. In particular, the plate holder 31 has an opening 35 for this purpose. Through this opening, an actuating element can extend through the plate holder 31 from below and thus contact the second support wing from below and lift it, so that it is pivoted about its horizontal axis C. Accordingly, on the side opposite the opening 35, a further opening is formed, which is located below the first support wing 33. This too can then be raised accordingly, as explained.Preferably, the opening 35 is covered from above by an elastic cover 36. The elastic cover 36 allows the actuating element to protrude through the opening 35 and be positioned higher than the upper side region 34b. Due to the elastic deformation of the elastic cover 36, a corresponding projection of the actuating element can be achieved. This then also allows the corresponding second support wing to be raised.

[0052] It is intended that the support wings 33 protrude outwards beyond the dimensions of the lifting unit 28 in a horizontal plane. This allows the insert plate 10 to be lifted using a single lifting unit 28. There is no need to provide multiple separate lifting units. However, due to the central positioning of the lifting unit 28 and a only single design of the lifting unit 28, the latter is also designed to be relatively space-saving in this horizontal plane. In order to prevent the insert plate 10, which would protrude significantly beyond the lifting unit 28 if only the lifting unit 28 were present, from undesirably tipping over, the support wings 33 designed for this purpose are provided. They thus project significantly beyond the dimensions of the lifting unit 28 in this horizontal plane. This allows the insert plate 10, which is larger in this respect, to be contacted more extensively directly on its underside. The support wings 33 thus create a particularly advantageous support structure.

[0053] In particular, the support wing 33 is V-shaped. It has a V-base 37. In addition, it has two V-legs 38 and 39. These project laterally away from the V-base 37. These V-legs 38, 39 are cantilevered. They extend from this centrally formed V-base 37 toward a corner region 40 and 41 ( Fig. 5 ) of the tub 2. In particular, the insert plate 10 is square, so that these V-legs 38 and 39 also extend towards corner areas 42 and 43 ( Fig. 3 ) of the insert plate 10 when the insert plate 10 is placed on the support wing 33 from above. The same applies to the extension of the V-legs of the second support wing (not shown). From this, the V-legs then extend to corner regions 44 and 45 ( Fig. 3 ) of the insert plate 10.

[0054] In the embodiment in Fig. 4 These V-shaped legs 38 and 39 are designed as uninterrupted, plate-like strips. The support wing 33 is made in one piece, in particular from plastic. The same applies to the Fig. 4 additional support wings not shown.

[0055] In Fig. 5 In a further exemplary embodiment, a perspective view of a sink 1 is shown. In this embodiment, the lifting device 28 is shown in the fully extended state. This means that the lifting device 28 has also moved fully upwards. In this embodiment, instead of two separate support wings, each having two integrated V-legs 38, 39, there are four separate support wings 33, 46, 47 and 48. The support wings 33, 46, 47 and 48 are therefore each designed as straight support arms. They can each be pivoted individually about horizontal axes, independently of the other support wings 33, 46 to 48. Corresponding actuating elements can extend through penetrations 35a, 35b, 35c and 35d and thus extend through in the direction of the longitudinal axis A in order to bring about the respective lifting of the insert plate 10.In particular, in these embodiments, these actuating elements act directly on the underside 10b of the insert plate 10. This is also the case because these support wings 33 and 46 to 48 are designed as a skeleton or as scaffold arms, thus enabling these actuating elements to extend through the respective support wings 33 and 46 to 48.

[0056] Preferably, it is provided that the insert plate 10 with the support wings 33 according to Fig. 4 and the support wings 33 and 46 to 48 according to Fig. 5 is coupled to a mechanical connection. This prevents rotation of the insert plate 10 about the longitudinal axis A. In particular, this mechanical connection is also such that a certain holding force is formed in the direction of the longitudinal axis A. This holding force in the axial direction is predetermined, in particular, by an individual force threshold value. This also makes it possible to ensure that, on the one hand, the insert plate 10 does not undesirably lift off or tip over upon slight contact with a support wing 33 or 33 and 46 to 48, but on the other hand, it can also be removed non-destructively by appropriately overcoming the force threshold value. In particular, the force threshold value can also be defined such that, if an object becomes wedged in the gap 26, this mechanical connection is automatically released. This can prevent damage or injuries.In particular, this holding force in the axial direction is also defined in such a way that the insert plate 10 is prevented from floating if water is present beneath the insert plate 10 when the insert plate 10 is lowered with the lifting device 11. This prevents the insert plate 10 from undesired detachment from a support wing if water is still present beneath the insert plate 10. In particular, it is provided that this water can be forced through the gap 26 above the insert plate 10.

[0057] This is especially true when the drain opening 27 is closed. If this drain opening 27 is open, the water can drain away properly and does not interfere with the downward movement of the insert plate 10.

[0058] This connection between the insert plate 10 and the support wing 33 or the support wings 33 and 46 to 48 can, for example, be an interlocking connection, such as a plug connection or a snap connection, or a magnetic connection. Combinations of these specific connections can also be provided. In particular, it is provided that, as shown in Fig. 6 As shown, a receiving structure 49 is integrally formed on the underside 10b of the insert plate 10. In the exemplary embodiment, this receiving structure 49 is designed as a recess. It has a complementary shape to the design of the support wings 33, or 33 and 46 to 48. Thus, these support wings dip into this structure 49 when the support plate 10 is placed onto these support wings.

[0059] In a further exemplary embodiment, in addition to or instead of the exemplary embodiments explained above, it can be provided that the underside 10b is uneven. In particular, this underside 10b can also be pyramid-shaped or conical. This allows for the targeted guidance of media, such as air or liquid, to take place. It can also be provided that the insert plate 10 is designed with an air vent structure for discharging air formed under the insert plate 10 toward an edge 25 of the insert plate 10. This air vent structure can be grooves in the underside 10b that lead to this edge 25.

[0060] It can also be provided that the lifting device 11 has an adjusting unit 50 ( Fig. 1 und Fig. 2 ). With the adjustment unit 50, the support wings 33 or 33 and 46 to 48 can be adjusted in a horizontal position in a common horizontal plane. It can also be provided that with this adjustment unit 50, a horizontal position of at least one support wing 33 or 33 and 46 to 48 can be adjusted, in which a top side 10a of the insert plate 10 is arranged flush with a top side of a visible component surrounding the insert plate 10 at the edge. This visible component can be, for example, a decorative frame or a mounting frame or an upper edge 2a of the tray 2.

[0061] Preferably, the support wings 33 or 33 and 46 to 48 extend to an outer third of the surface of the insert plate 10.

[0062] Preferably, the support wings 33 or 33 and 46 to 48 can be removed and reattached from the lifting unit 28 in a non-destructive manner.

[0063] Merely as an example, Fig. 5 a representation is shown in which the sink 1 is inserted into a recess 51 of a worktop 52.

[0064] A disassembly mode different from the normal mode of the lifting unit 28 can also be set. In this disassembly mode, the lifting unit 28 is adjusted to a position even higher in height than the maximum raised position of the lifting unit 28 in normal mode and thus also the corresponding position of the insert plate 10. In the maximum raised position in normal mode, it is provided in particular that the upper side 10a of the insert plate 10 is flush with the upper side of the upper edge 2a of the tub 2 or a decorative frame or a mounting frame. In the disassembly position which is higher thereto, the insert plate 10 is preferably positioned such that its underside 10b is arranged a vertical distance higher than this upper edge 2a. In particular, this vertical distance is at least 2 cm, in particular at least 3 cm.As a result, the insert plate 10 can be grasped by one hand at its edge 25 and held securely for removal from the lifting unit 28. The disassembly position is, in particular, a horizontal position of the insert plate 10. The underside 10b of the insert plate 10 is thus positioned completely above the upper edge 2a.
