Description

[0001] One aspect of the invention relates to a sink with a basin. The basin has a bottom wall and adjoining side walls. The basin has a receiving space bounded by the walls. Furthermore, the sink has a separate insert plate, which is inserted into the receiving space. The sink has a lifting device by which the insert plate can be moved relative to the basin, and the sink has at least one residual media drainage device by which residual media can be drained from the top of the insert plate.

[0002] Sinks of this type are known. For example, CN 106579805 A discloses a kitchen cabinet with a two-part sink and a tap located behind the sink. A lifting plate is mounted inside the sink and is movable by means of a push rod.

[0003] From CN 109695275 A a vegetable washing basin with an automatic lifting device, which is controlled by a switch, is known.

[0004] US Patent 2005 / 0067747 A1 discloses a sink with a basin. A plinth, integrally formed with the basin floor and extending upwards, is integrated into the basin floor. A plate can be placed on this plinth, creating a cutting board for chopping items such as food. This design has the disadvantage that the integrated plinth is always present, resulting in a more complex overall design of the basin and significantly restricting the available space. Furthermore, the plate, which can be placed on the plinth, is always at a single height. It can only be attached or removed by one user.

[0005] Furthermore, a sink is known from DE 362 1151 A1. Various inserts are provided separately from the basin, which can be placed in the receiving area. The inserts can be plates or other basin-like containers. These can be placed on the upper edge of the basin. This also severely restricts the usability of the sink, as the inserts must be attached or removed by a user and can only be positioned in one specific way.

[0006] The object of the present invention is to provide a sink with a basin and a separate insert plate, in which the insert plate can be kept clean.

[0007] This problem is solved by a sink according to claim 1.

[0008] One aspect of the invention relates to a sink with a basin. The basin has a bottom wall and adjoining side walls. The basin also has a receiving space bounded by the bottom wall and the side walls. The receiving space is open at the top. The sink has a separate insert unit, in particular an insert plate, especially a continuous and perforated insert plate. This insert plate can be placed in or is inserted into the receiving space. The sink also has a lifting device with which the insert plate can be moved vertically relative to the basin. This is made possible by a lifting device within the sink. Thus, a sink is provided in which the insert unit can be positioned at different heights.This is further enhanced by a lifting device, eliminating the need for manual adjustment by the user. Essentially, the lifting device allows for continuous height adjustment of the insert plate. This enables the insert plate to be positioned and set at numerous different height levels.

[0009] The sink also features an active residual media drainage system. This system allows residual media to be removed from the top of the insert plate. The drainage system is a physical device comprised of functional components. This design makes it possible to keep the insert plate, especially its top surface, clean. It also enables cleaning as needed. In particular, it prevents the accumulation of residual media on the top surface. Residual media are generally defined as media that can remain on the top of the insert plate for an extended period. For example, this could be liquid that remains on the top of the insert plate and would not drain away. Other solid media can also be considered residual media.

[0010] According to the invention, the residual media removal device comprises an electromechanical device.

[0011] In particular, the residual media drainage device is designed to include a movement unit. This movement unit is configured to move the insert plate in a defined manner to drain the residual media. This allows the sink to be operated in a specific drainage mode. In this drainage mode, which differs from the sink's normal mode, a drainage process for residual media is carried out on the top surface of the insert plate. This design therefore ensures that the residual media is drained by a specific movement of the insert plate. Specifically, a defined drainage movement of the insert plate can be initiated. This is achieved primarily through the sink's movement unit. This design enables comprehensive and demand-based drainage of residual media.

[0012] Preferably, this defined drainage movement of the insert plate is such that the residual media enter the receiving chamber of the tray and can then be transported away via a drain opening. This prevents the residual media from spilling out of the tray and, for example, onto an adjacent work surface, provided this drainage of the residual media is carried out in a controlled manner. In a further embodiment, the movement of the insert plate initiated by the motion unit for draining residual media can be a tilting movement of the insert plate. In particular, such a movement is a tilting movement relative to a horizontal plane. Additionally or instead of this, such a movement of the insert plate for draining residual media can be a rotation about a vertical axis. The tilting movement very advantageously allows liquid media to drain from the top of the insert plate.A defined tilting position is thus set, enabling a precisely measured drainage of these residual media. Particularly advantageous in this drainage mode and with the set tilting position is the ability to drain directly into the receiving chamber. This allows for the automatic drainage of the residual media contained in the receiving chamber through a drain opening in the tray. Essentially, this allows for the removal of residual media from the top of the insert plate without direct user intervention. For example, explicit wiping with a cloth or similar material is no longer necessary.

[0013] Similarly, a separate rotation, or one performed in conjunction with the tilting movement, can cause residual media to be flung off the top of the insert plate. Preferably, during rotation, the insert plate is brought into a position that is at least partially lowered. This means that the insert plate is not positioned at its maximum upper height. Such a partially lowered position ensures that, viewed vertically, the top of the insert plate is positioned below the upper edge of the tub. Any residual media flung off during rotation are then, if at all, flung against the inner sides of the vertical walls of the tub and are not thrown beyond the tub.If the rotation is performed at a reduced speed, it is possible to precisely control the amount of residual media being conveyed to the edge of the insert plate and from there, without being strongly flung against the side walls, downwards into the receiving chamber of the base wall. A combined tilting and rotating motion can also be used as a discharge movement to remove the residual media from the top of the insert plate. In an advantageous embodiment, this also results in a wobbling motion.

[0014] This drainage mode can be controlled by a control unit of the sink. This allows for individual adjustment of both the duration and the type of movement of the insert plate for draining residual media. For example, the process can begin with a rotational movement followed by a tilting motion. Similarly, it can begin with a tilting motion followed by a rotational movement. A tilting and a rotational movement can also be performed simultaneously. It is also possible to adjust the tilting position during the drainage mode to achieve a greater or lesser degree of drainage of residual media from the top. Additionally, or alternatively, the rotational speed of the insert plate can be changed during the drainage process. This can be done, for example, by a predefined program during the drainage process.However, it is also possible for the sink to have at least one sensor that detects the top of the insert plate. Depending on this information, the drainage process can then be individually adjusted. Additionally, or instead, it is possible for the drainage process to be individually modified during its execution, particularly depending on the information detected by the sensor.

[0015] In an advantageous embodiment, the residual media removal device may include at least one airflow generation unit for the rinsing basin. This airflow generation unit can produce a defined airflow directed towards the top of the insert plate. In particular, this enables contactless removal of the residual media from the top. The intensity and direction of this airflow can be individually adjusted.

[0016] In a further advantageous embodiment, the residual media drainage device may include a slide gate. This slide gate can be slid across the top of the insert plate to drain residual media. In particular, the sink may have a motor that drives this slide gate. This slide gate can be linearly displaceable. It can also be rotated, either additionally or instead of being linearly displaceable.

[0017] In a further advantageous embodiment, the residual media drainage device is provided with a movable flap or slide that opens or closes a drainage chute in the insert plate for the removal of residual media from the top via the drainage chute. This allows such a residual media drainage device to be integrated directly into the insert plate itself. The integrated drainage chute allows the residual media to be collected in a targeted and directed manner and then discharged from the top of the insert plate via the drainage chute. The flap or slide prevents the drainage chute from being permanently open. This allows for a smooth and flat top surface while enabling the drainage chute to be opened as needed. This is particularly relevant in the drain mode of the sink. The flap or slide can be mechanically actuated.In particular, this can be done directly by a user. However, it can also be provided that this flap or slide is controlled, opened, or closed by a control unit.

[0018] The residual media drainage device may also include a vibration unit. This unit vibrates the insert plate, allowing for the targeted removal of residual media from the top surface. In particular, the residual media drainage device may also include a deformation unit. This unit allows the top surface of the insert plate to be temporarily and elastically deformed to facilitate the removal of residual media. This can be done, for example, in a controlled drainage mode of the sink. The deformation unit allows the insert plate to be shaped in a defined manner during drainage mode, enabling the directed and targeted removal of residual media from the top surface. This is advantageous if at least the top surface of the insert plate is elastically deformable for this purpose.

[0019] The deformation unit may include at least one movable piston. This piston can act on the insert plate to deform it in a defined manner. For example, the piston can be a push piston that presses down on the insert plate to create the desired deformation. Alternatively, it can be a suction piston that pulls on the insert plate from below. The piston can be mechanically, hydraulically, or electromechanically operated. It can be controlled by a control unit of the sink. In particular, an elastic deformation, such as an upward bulge, is intended, giving the insert plate a dome-like top surface. This allows residual media to be drained evenly in all directions. However, it is also possible for a localized deformation to occur, creating, for example, a channel-like depression.

[0020] In particular, a plate receptacle for the insert plate is formed in the upper region of the upper lifting segment. This plate receptacle can, for example, be implemented as an injection-molded component, especially as a two-component injection-molded component. It can be provided that this plate receptacle has at least one through-hole. An actuating element can extend through this hole from below, with which a support wing positioned on the plate receptacle can be raised. In particular, this raising action can cause a pivoting motion about a horizontal pivot axis, so that a support wing can be tilted and thus positioned at an angle. Preferably, such a hole or through-hole in the plate receptacle is covered in its upper region by an elastic component. This prevents media from entering this hole in the plate receptacle from above.Because this cover is elastically designed, the actuating element can act upon it and bend it upwards. This allows a corresponding actuating force to be transferred to the support wing, causing it to tilt.

[0021] In an advantageous embodiment, the upper surface of the insert plate has an area that is at least 80 percent, in particular at least 90 percent, and in particular at least 95 percent of the area of ​​the receiving space in a horizontal plane. However, the area of ​​the upper surface of the insert plate is less than 99 percent of this area of ​​the receiving space. This dimensioning ensures that the insert plate forms a virtually full surface area with respect to the clear width of the receiving space between the side walls, thus almost completely filling this receiving space in the horizontal plane. At the same time, a small gap, in particular between 3 mm and 15 mm, and in particular between 3 mm and 10 mm, is maintained around the perimeter, allowing the relative movement of the insert plate to occur unimpeded during position adjustment or changes.In particular, this prevents direct contact and potential rubbing of an edge of the insert plate against the inner sides of the side walls. This prevents damage to the side walls, the insert plate, and the lifting device. Finally, this design also advantageously allows any liquid present on the top of the insert plate to easily drain into the receiving chamber through the gap between the edge of the insert plate and the inner sides of the side walls.

[0022] Preferably, the tub has a drain, particularly at the bottom. This allows any medium that collects in the tub to drain away easily.

[0023] In particular, the tub, including the base and side walls, is formed as a single piece. Specifically, the tub is made of metal.

[0024] The floor wall can be flat, slightly inclined, or slightly curved. In particular, it is stipulated that the point on the floor wall where an outlet for the sink drain is located is positioned furthest down in terms of height.

[0025] The top surface of the insert plate can be completely flat. However, it can also have a slight curvature. It is also possible for the top surface of the insert plate to be textured, at least in some areas. This creates a certain degree of roughness, which helps prevent unwanted slippage of objects placed on it. This is advantageous, for example, if the insert plate is moved and objects are still positioned on its surface. Similarly, the top surface can have specific positioning areas, such as indentations. These indentations can be relatively shallow, which is advantageous for more secure positioning of containers like glasses. This is particularly beneficial when a change in position involves tilting and / or rotating.Unwanted slippage of such containers is thus prevented. Furthermore, these predefined positioning areas also ensure that, for example, when containers are placed on top of the insert plate and are to be filled via the tap, the water flowing from the tap is directed precisely into the containers during a rotational movement and does not spill over the sides of the containers onto the insert plate.

[0026] The lifting device can include a lifting unit and a motor. The motor allows the lifting unit to be moved, at least in the vertical direction.

[0027] 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.

[0028] Further features of the invention can be found in the claims, the figures and the description of the figures.

[0029] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a schematic sectional view through an embodiment of a sink 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 to Fig. 1 different second position; Fig. 3 a top view of an embodiment of a sink; and Fig. 4 a schematic sectional view through an embodiment of a sink according to the invention with an insert plate in a tilted position.

[0030] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0031] In Fig. 1A schematic vertical section view (xy-plane with height direction y and width direction x) shows a sink 1. The sink 1 has a basin 2. The basin 2 has a bottom wall 3 and adjoining side walls 4, 5, 6 extending upwards. Fig. 3 ) and 7 ( Fig. 3The basin 2 is preferably made of metal. The basin 2 has a receiving chamber 8. The receiving chamber 8 is bounded by the aforementioned walls 3 to 7. Thus, the basin 2 has an upper loading opening 9. The sink 1 also has an insert unit. The insert unit is preferably an insert plate 10. The insert plate 10 is preferably made of metal. The insert plate 10 is a component of the sink 1 separate from the basin 2. The sink 1 further 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 allows it to be removed without damage. The lifting device 11 allows the insert plate 10 to be moved relative to the basin 2. In this context, movement in the vertical direction (y-direction) of the sink 1 can occur.Additionally or instead of this, the lifting device 11 can be rotated about a vertical axis A. Additionally or instead of this, the insert plate 10 can be tilted. This means that the insert plate 10 can be adjusted with its plane at an angle to a horizontal plane. It can thus be tilted or positioned at an angle. Fig. 1 The insert plate 10 is shown in an exemplary position in the recording chamber 8. Specifically, this is a downward-facing position. In this respect, the insert plate 10 is positioned directly adjacent to the floor wall 3.

[0032] Preferably, the sink 1 has an interaction unit 12. The interaction unit 12 can be a display unit 13 ( Fig. 3The interaction unit 12 may include an operating device 14. The operating device 14 may have one or more operating elements. The operating elements may be pushbuttons, switches, toggle switches, or rotary knobs. However, the operating device 14 may also additionally or instead include a touch-sensitive control panel 15. In an advantageous embodiment, the interaction unit 12 may include at least one optical detection unit 16. The optical detection unit 16 may, for example, be a camera. The camera may be sensitive in the spectral range visible to humans. However, the interaction unit 12 may also additionally or instead include an acoustic unit 17. This acoustic unit 17 may be configured to receive and / or output speech signals. Furthermore, the interaction unit 12 may include 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. Additionally or instead of this, the identification unit 18 can also include, for example, the acoustic unit 17. This allows the user to be identified, for example, by evaluating a voice signal. Additionally or instead of this, the identification unit 18 can be a unit for capturing and evaluating a biometric characteristic of a user. For example, this could be a fingerprint sensor or a sensor for recognizing an iris pattern.

[0033] As in the Figs. 1 to 3As 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 permanently and non-destructively formed 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, here the side wall 5 in the example, also forms a boundary wall for the receiving volume 20 of the receiving housing 19.

[0034] This separates the intake volume 20 from the intake space 8 of the tub.

[0035] In Fig. 2 is the representation according to Fig. 1 shown, however, the insert plate 10 in a too Fig. 1 shown in different positions. Fig. 2The insert plate 10 is oriented horizontally but positioned at an upward angle. This position represents the maximum possible height in normal mode. Specifically, in this position, an upper surface 10a of the insert plate 10 is flush with an upper edge 2a of the basin 2. In this position, the insert plate 10 forms a cover or lid for the receiving space 8. This upper edge 2a can also be, for example, the upper surface of a mounting frame or a decorative frame that is part of the sink 1. The mounting frame allows the sink 1, and in particular the basin 2, to be mounted in a recess in a worktop. A decorative frame can be used to cover the basin 2 from above. A gap between the basin 2 and a boundary wall in the worktop that defines the recess can thus be covered from above. Such a decorative frame constitutes, in particular, a visible upper component of the arrangement.

[0036] In particular, 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.

[0037] Sink 1 can be, as shown in the simplified top view in Fig. 3 The sink 1 can be identified as having a tap 22, preferably also a tap 22. The tap 22 constitutes a functional unit of the sink 1. Likewise, the interaction unit 12, in particular the operating device 14, can be considered a functional unit of the sink 1. The insert plate 10 can be another functional unit of the sink 1. The lifting device 11 can also be another functional unit of the sink 1.

[0038] The lifting device 11 preferably comprises a lifting unit and a motor. This allows its length or height to be changed in the direction of the vertical axis A. Furthermore, it can be rotated about the vertical axis A, either additionally or instead. This enables a rotational movement about this vertical axis A as a position or change of position for the insert plate 10. Finally, the lifting device 11 can also be adjusted so that the insert plate 10 can be tilted or inclined relative to a horizontal plane.

[0039] The interaction unit 12 detects the operating state of the sink 1 and / or a change in the operating state of the sink 1 and / or an operating action by 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 for the automatic position change of the insert plate 10. Fig. 3Furthermore, 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 finger 23. In particular, the gesture is a non-contact gesture. In addition or instead, however, the control 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 control device 14. An operating state can, for example, be a setting of the control device 14 and / or a change in the operating state can be a change in the setting of the control device 14.

[0040] A change in position of the insert plate 10 can depend on the type and / or strength and / or duration of an operating state of at least one functional unit of the sink 1 and / or a change in position can depend on the type and / or strength and / or duration of a change in the operating state of at least one such functional unit of the sink 1.

[0041] The interaction unit 12 has a normal mode. In this mode, the actual operation of the sink 1 is recorded. In addition, the interaction unit 12 has a definition mode that differs from the normal mode. This mode can be set, for example, by a user. In this definition mode, at least one user can 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 saved as a user profile in a storage unit 24 of the interaction unit 12.

[0042] In an advantageous embodiment, it is provided that the in Fig. 3The area shown (depth direction z and width direction x) of the top surface 10a is at least 80 percent, in particular at least 90 percent, in particular at least 95 percent of the area of ​​the recording space 8, which lies in a horizontal plane (in Fig. 3The area of ​​the top surface 10a is considered in the horizontal plane. In particular, this area of ​​the top surface 10a is less than 99 percent of the area of ​​the receiving space 8 in the aforementioned horizontal plane. This results in a circumferential edge 25 of the insert plate 10 being spaced apart from the side walls 4, 5, 6, and 7. Specifically, 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 small enough, at least in the horizontal position of the insert plate 10, that objects such as cutlery or the like cannot slip through it. The pinching of a finger 23 is also then avoided in this horizontal position of the insert plate 10.

[0043] As in the Figs. 1 to 3As further shown, the sink 1 has a drain opening 27, for example, a drain. This is formed in particular in the bottom wall 3. Through this drain opening 27, media from the receiving chamber 8 can drain out of the basin 2.

[0044] In Fig. 4 A schematic diagram shows a sink 1 with a residual media drainage device 28. The residual media drainage device 28 is designed for the controlled drainage of residual media onto the upper surface 10a of the insert plate 10. The sink 1 may be equipped with a control unit 29. This control unit 29 allows the residual media drainage device 28 to be controlled; in particular, a drainage mode for the sink 1 can be set in which the residual media drainage device 28 is activated. The residual media drainage device 28 may, in particular, be an electromechanical device.

[0045] In the Fig. 4In the illustrated embodiment, the residual media discharge device 28 is designed to tilt the insert plate 10 relative to a horizontal plane. Fig. 4 The residual media drainage tilting position of the insert plate 10 is shown in this context. In particular, this is a tilting position that represents a relatively small stroke compared to the horizontal position H. The horizontal position H is shown here with a dashed line. Specifically, the height difference d of an edge 25 of the insert plate 10 between the horizontal position and the residual media drainage tilting position is 5 mm, and more specifically between 2.5 mm and 4 mm.

[0046] In particular, the residual media discharge device 28 has a movement unit 30 for carrying out such a tilting movement of the insert plate 10.

[0047] Additionally or instead, the residual media removal device 28 may include a rotation unit 31 for the defined removal of residual media from the upper surface 10a of the insert plate 10. This rotation unit 31 may be part of the motion unit 30 or a separate unit. The insert plate 10 can be rotated about axis A by this rotation unit 31. This can also be done, in particular, in a removal mode. Both the motion unit 30 and the rotation unit 31 can be controlled via the control unit 29.

[0048] Additionally or instead, the sink 1, in particular the residual media drainage device 28, may be provided with an airflow generation unit 32. This is located in Fig. 4Both the position and the design are to be understood symbolically through the box. This airflow generation unit 32 allows an airflow to be generated in a targeted manner and directed towards the upper surface 10a of the insert plate 10. This allows residual media to be blown off the upper surface 10a.

[0049] It is also possible for the residual media discharge device 28 to have a slide 33 in addition to, or instead of, the existing one. This slide can be mounted directly on the top surface 10a and moved or rotated relative to the top surface 10a. In particular, a motor (not shown) can be provided for this purpose. Thus, the slide 33 can also be controlled via the control unit 29.

[0050] It may also be provided that the residual media discharge device 28 has a movable flap or slide.

[0051] This can be opened or closed to release or block a discharge chute formed in the insert plate 10. The discharge chute can be a channel open towards the top 10a, extending particularly towards the edge 25. However, this discharge chute can also have a continuous opening in the insert plate 10 as an end piece, terminating before the edge 25. It is also possible for the discharge chute to be not an upwardly open channel along its length, but rather a channel closed towards the top 10a. In this configuration, the beginning of the discharge chute is open towards the top 10a, while the rest of the discharge chute is closed towards the top 10a. This effectively forms an integrated, internal channel within the insert plate 10. This channel can terminate at the edge 25 at its opposite end, providing an outlet.However, it may also be provided that the channel additionally or instead has an opening to the underside 10b spaced apart from the edge 25.

[0052] Additionally or instead, the residual media discharge device 28 may be provided with a vibration unit 34. This vibration unit 34, which can be controlled in particular via the control unit 29, can vibrate the insert plate 10 to discharge residual media from the top 10a.

[0053] Additionally or instead of this, the residual media discharge device 28 may include a deformation unit 35. This unit allows the upper surface 10a of the insert plate 10 to be temporarily deformed in a defined manner for the purpose of discharging residual media. This deformation unit 35 can, for example, be a rod that presses against the insert plate 10 from below. This can then deform the insert plate 10 into a symmetrical or asymmetrical dome. Alternatively, this deformation unit 35 can also exert a downward pull, deforming the upper surface 10a into a funnel or a channel. For example, instead of a rod, the deformation unit 35 can also be designed as a push or suction plunger.

[0054] A disassembly mode different from the normal mode of the lifting unit of the lifting device 11 can also be set. In this mode, the lifting unit is set to a position even higher than its maximum raised position in normal mode, and thus also to a position corresponding to the insert plate 10. In the maximum raised position in normal mode, it is specifically provided that the upper surface 10a of the insert plate 10 is flush with the upper surface of the top edge 2a of the tray 2, or with a decorative frame, or with a mounting frame. In the higher disassembly position, 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, and more specifically, at least 3 cm.This allows the insert plate 10 to be gripped by one hand at its edge 25 and held securely for removal from the lifting unit. 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.
