Description

Food placement unit for a household appliance and household appliance

Technical Field

The utility model relates to a food placing unit for household appliances. The food placement unit has an adjustment device for height adjustment of the food placement unit on a household appliance component of the household appliance. Furthermore, the invention also relates to a household appliance device with such a food holding unit. Furthermore, the invention also relates to a household appliance (in particular a household refrigerator appliance) having at least one food storage unit.

Background

A wide variety of food-holding units for domestic appliances, in particular domestic refrigeration appliances, are known. For example, it is known for the food placement unit to be a shelf (Fachboden) which can be inserted into a refrigerating or freezing compartment of a domestic refrigerator. Such compartments may thus separate the volumes of such storage compartments. However, the compartment floor can also be a lower bottom wall which delimits the storage compartment from below.

However, the food resting unit may also be a trough-like container which is arranged in the storage compartment. Another example for a food resting unit may be a door shelf arranged on a door of such a household appliance, in particular a household refrigeration appliance.

In this case, embodiments are also known in which such food resting units can be adjusted in height by manual action of the user. In this case, for example, the grid base can be pushed in at different height levels. In door shelves, it is known that they can be adjusted in height by being manually moved by the user.

In such a configuration, the user must usually grasp the food placement unit with both hands and then, by means of corresponding force, also bring it into the desired position, or even remove it from the storage compartment beforehand. In this case, a situation that is not user-friendly may occur due to jamming or wedging that may occur due to inaccurate hand operation. Furthermore, damage to the food-holding unit or to the components of the household appliance can also occur as a result of such jamming or wedging.

From the prior art, cold storage appliances are known which have a shelf and a support unit, wherein the shelf is supported by the support unit, and wherein the shelf can be adjusted upward and downward in a stepless manner.

SUMMERY OF THE UTILITY MODEL

The task of the present invention is, inter alia, to provide a food placement unit with improved properties with regard to operating comfort. The object is also to provide a household appliance having a food placement unit.

This object is achieved by a food resting unit for a household appliance and a household appliance according to the invention.

An aspect of the present invention relates to a food resting unit for a household appliance. The food placement unit has an adjustment device for: the height adjustment of the food placement unit is carried out when the food placement unit is arranged on a household appliance component of the household appliance. The adjustment device has at least one separately independent motor-driven unit, which is arranged on the food resting unit itself. A highly functional food-holding unit is formed by such a configuration. Since the motor drive unit makes it unnecessary for the user himself to use the corresponding force for effecting a change in position (in particular to exert a corresponding force in the correct direction), but rather the motor carries out this change in position. Furthermore, the motor-driven unit is not arranged externally with respect to the food resting unit, but directly on the food resting unit itself. The motor-driven unit is therefore integrated to some extent into the food resting unit. This also means that: the motor drive units always carry out the movement of the food placement unit together, since the motor drive units are arranged in a stationary manner on the food placement unit. This type of configuration also avoids complex cabling. Furthermore, short circuit paths can also be implemented in the mechanical coupling device, which is to be coupled to the motor drive unit in order to also be able to adjust the height of the food placement unit.

It is preferably provided that the motor-driven unit is arranged within the height of the food placement unit, as seen in the height direction of the food placement unit. In particular, the motor-driven unit is arranged completely within the height of the food resting unit. A particularly compact construction can be achieved by this type of configuration, and the motor drive unit does not project upwards or downwards.

Preferably, the food placement unit has a food placement plate, wherein the motor drive unit is arranged on the placement plate. The support plate forms a mechanically stable and loadable component, so that it can also be used as a reliable carrier for the motor drive unit. The food placement unit can be formed merely by a placement plate when it is, for example, a shelf or floor wall. If the food resting unit is a container, in particular a basin-type container, the resting plate can for example be constituted by the bottom of the container.

It is preferably provided that the placement plate has, on at least one narrow edge (Schmalrand) that it has, a mounting recess (einbaunesche) that is open toward the rear and in which the motor drive unit is arranged. In particular, the narrow edge is a narrow edge on the back side (seen in the depth direction of the food resting unit). By mounting the motor drive unit in such a mounting pocket, the motor drive unit is also arranged in a protected manner and is thus protected against impacts from other components. It is thereby also avoided that the items (or food) placed on the resting plate may also directly influence the motor-driven unit.

The assembly recess therefore has at least one top, so that the motor drive unit is protected at least from above. The assembly recess is preferably delimited by a top wall, side walls adjoining it and preferably also by a floor wall, so that the assembly recess is delimited to some extent by a surrounding frame (or a surrounding web). A particularly advantageous receptacle and housing of the motor drive unit is thereby achieved. With the mounting pocket open to the rear, the motor drive unit and, if necessary, further components arranged in the mounting pocket are always accessible. This makes it possible to achieve a simple and user-friendly access (Zugang) during installation work or maintenance work.

The assembly cavity may be covered by a separate and independent cover (Abdeckung).

Preferably, a component assigned to the synchronization unit of the adjustment device is arranged in the assembly recess. The synchronization unit is designed to synchronize the movement of two separate coupling elements, which are designed to be coupled to a rolling bar (Abrollstan) outside the placement unit. This type of synchronization unit can thus be realized in a synchronized operation of the separate independent coupling elements, which are preferably arranged on opposite sides of the food placement unit. In this way, a uniform movement of the food placement unit in the height direction is achieved in the state in which the coupling elements are coupled with rolling bars, which are not an integral part of the food placement unit. Tipping or jamming can thereby be avoided. By arranging such components of the synchronization unit in the assembly recess, a particularly short line path between the motor drive unit and these components can be achieved here. A mechanically highly effective and highly functional coupling system between the motor drive unit and the synchronization unit is thereby achieved. A particularly accurate synchronization is thereby also achieved.

Preferably, at least one motor-driven unit is coupled to a slip coupling/slip clutch (Rutschkupplung) of the food placement unit. Thus, the sliding coupling is also arranged directly on the food resting unit. The configuration of the food resting unit with the sliding coupling is a particularly advantageous embodiment. Since the motor drive unit is not directly coupled to the further components of the adjusting device, a very desirable force transmission can take place via the sliding coupling. Overload of the motor drive unit (in particular when the food placement unit is widely occupied by stored goods) can thereby be avoided. This allows a particularly desired and situation-adapted movement design and a particularly good, low-wear operation of the motor drive unit. Furthermore, it is also achieved by the sliding coupling: when the motor drive unit is started, no sudden force transmission to the parts of the adjusting device coupled thereto occurs unintentionally, so that no sudden overload of these further parts occurs unintentionally.

A slip coupling is a safety coupling that automatically switches torque. The sliding coupling is preferably designed such that it is arranged between the two shafts. When the defined torque is reached, the slip coupling is disengaged without external (extraneous) influences. In addition to synchronous operation, the shafts can also be operated at different rotational speeds until one shaft stops. Overload of the drive unit (for example when a number of stored items and/or heavy stored items are arranged on the food placement unit) can thereby be avoided.

Preferably, the adjusting device has a synchronization unit, which is designed to synchronize the movement of two separate, independent coupling elements of the adjusting device, which are designed to be coupled to a rolling bar outside the placement unit. The mentioned slip coupling is preferably coupled between the motor drive unit and the synchronization unit. The advantages already mentioned above in connection with the sliding coupling are in particular covered here. It is therefore the synchronization unit that can be operated with the expected and possibly metered force application from the motor drive unit, so that here too a particularly uniform movement synchronization of the coupling elements can be achieved.

Preferably, it is provided that the sliding coupling is arranged in an assembly recess which is formed on a narrow edge of a placement plate of the food placement unit. This configuration also allows a space-saving and protected arrangement of the sliding coupling.

It is preferably provided that the adjustment device has a first motor drive unit and a second motor drive unit which is separate and independent therefrom, wherein the two motor drive units are arranged directly on the food placement unit itself. By means of such a redundant configuration with a plurality of motor-driven units, separate, independent coupling elements arranged on the food placement unit can be driven individually. By such an at least double arrangement of the drive design, the motor drive units can also be configured to be smaller if necessary.

In an advantageous embodiment, it is provided that the placement plate has a laterally open assembly recess on at least one second narrow edge (in particular a first lateral narrow edge) of the placement plate, in which assembly recess a first motor drive unit is arranged. In addition or alternatively, it can be provided that the placement plate has a further laterally open installation recess on at least one third narrow edge (in particular the second lateral narrow edge), in which the second motor drive unit is arranged. Preferably, the second narrow edge and the third narrow edge extend in the depth direction of the food resting unit. In particular, the two lateral narrow edges are configured on opposite sides of the resting plate when the food resting unit is viewed in the width direction.

Preferably, the two motor drive units are coupled via a synchronization unit of the adjustment device, wherein the synchronization unit is designed to synchronize the drive units in a rotational speed regulation (drehzahlegulieren). In this way, a precise synchronization of the motor drive units is achieved in a particularly advantageous manner, so that here too a very precise uniform transmission of force to the coupling elements respectively coupled to the motor drive units is possible. In this embodiment, therefore, a particularly uniform adjustment of the height is also possible without the food placement unit tipping over and thus without unintentional jamming or jerking of the movement.

Preferably, the first motor drive unit is coupled to a first sliding coupling, and the second motor drive unit is coupled to a second sliding coupling that is separate and independent from the first sliding coupling. The advantages that can be achieved by the sliding coupling have already been mentioned above. Here, the sliding coupling device couplings are individually adapted to the respective couplings with the motor drive unit.

In an advantageous embodiment, it is provided that the adjusting device has two separate and independent coupling elements which are designed to be coupled to a rolling bar outside the placement unit. The adjusting device has a first worm gear, which is coupled to the first coupling element and to the first motor drive unit. In particular, this coupling takes place via a first sliding coupling which is coupled to the first motor drive unit. In addition or alternatively, the adjusting device has a second worm gear, which is coupled to the second coupling element and to the second motor drive unit. In this case, this coupling is also achieved in particular by means of a second sliding coupling which is coupled to the second motor drive unit. An additional, very compact design can be achieved by this coupling design (in particular by the worm gear). Furthermore, a particularly precise and precisely metered force transmission to the coupling element can be achieved, so that a very finely metered height adjustment is achieved.

In an advantageous embodiment, it is provided that the worm gear mechanisms are also arranged in the narrow edges of the placement plate (in particular in assembly recesses) which are formed on the narrow edges of the placement plate.

It is preferably provided that all components of the adjusting device which are arranged on the food placement unit are arranged (in particular completely) within the height of the food placement unit (in particular the placement plate) in the height direction of the food placement unit.

In an advantageous embodiment, it is provided that the motor drive unit has an electric motor. The electric motor is very space-saving and compact in design and nevertheless achieves a very rapid and precise generation of corresponding forces for driving the coupling elements of the adjusting device, which can then be rolled on the rolling bar of the household appliance device.

Preferably, the coupling elements are configured as gears. These rolling bars preferably have teeth, which are designed as toothed racks/bars (Zahnstang), in which the coupling elements are directly coupled (or clamped).

The motor drive unit can be supplied with energy in a self-contained manner (autark). Wireless energy transfer may also be achieved. Likewise, further designs for transmitting energy to the motor drive unit can also be provided.

In an advantageous manner, the adjusting device is an integral part of the bearing unit. The support unit is a component of the household appliance device. Advantageously, the support unit has, in addition to the adjusting device, a rolling bar on the outside of the resting unit. These rolling bars may be arranged on the domestic appliance component. The household appliance component can preferably also be a component of a household appliance device. The domestic appliance component can be, for example, an inner container of a domestic refrigerator, which delimits a refrigerating compartment or freezing compartment, and in particular a storage compartment, with its walls. Preferably, in this case, the household appliance component may be a vertical side wall of the inner container. Likewise, the household appliance component can however also be a beam. The beam may, for example, be arranged on the inner side of a door of the domestic refrigeration appliance and may extend in the height direction.

Furthermore, a further aspect of the invention relates to a household appliance (in particular a household refrigerator) having a household appliance component and at least one food placement unit according to the above-mentioned aspect or advantageous configuration. The food placement unit is arranged on the household appliance component in a height-adjustable manner in the height direction of the household appliance by means of at least one motor-driven unit.

In an advantageous embodiment, it can be provided that the food placement unit has an operating element by means of which the user can perform a motor-driven height adjustment. For example, an operating element in the form of a key can be provided here. In such a configuration, the user must manipulate the operating element, for example with a finger. It may also be provided that such an operating element is a proximity sensor(s) ((

) The proximity sensor recognizes the actuation request when an actuating element, for example a finger, approaches and thus enables a contactless activation. It can also be provided that a remote control is provided, by means of which the activation of the height adjustment can be effected wirelessly. So-called Smart Devices (Smart Devices) may also be provided. Smart devices are in particular information technology-oriented components which are added value by information processing and communication in a sensor-supported manner. In particular, such intelligent devices areAn internet-enabled device.

The placement unit is provided in particular for placing and/or supporting objects (in particular food).

In particular, a household appliance device (in particular a household refrigerator device) is also proposed as a further aspect of the present invention, which has at least one body and at least one food placement unit, which is fastened to the body in at least one operating state and is provided for storing goods. In particular, the household appliance device has at least one support unit which enables the food resting unit to be supported on the body in a height-adjustable manner in a stepless manner (stufenlos). The support unit has in particular at least one first coupling element and at least one second coupling element, and preferably at least one synchronization unit which is configured differently from the food placement unit and which, in the operating state and when the food placement unit is adjusted in height, transfers a movement of the first coupling element relative to the food placement unit at least substantially via a lateral region of the food placement unit into a corresponding movement of the second coupling element relative to the food placement unit.

A "household appliance device" is to be understood to mean, in particular, at least one part (in particular a subassembly) of a household appliance. Advantageously, the domestic appliance is configured as a domestic refrigeration appliance. Particularly advantageously, the domestic refrigeration device is provided for: in at least one operating state, the refrigerated goods (in particular food items such as drinks, meat, fish, milk and/or milk products) are cooled, in particular in order to achieve a longer durability of the refrigerated goods. The domestic refrigeration appliance may be a freezer, in particular, and advantageously a refrigerator and/or freezer. Alternatively, the household appliance can also be designed as a cooking appliance (in particular as an oven) or as a dishwasher.

"bulk" (Korpus) is to be understood in particular as meaning a unit: the unit forms a part (in particular a majority) of the outer boundary of the housing (advantageously the outer housing) in at least one operating state and delimits a part (in particular a majority) of the outer boundary of at least one receiving chamber (in particular the refrigerating chamber and/or the freezing chamber) in this operating state.

The support unit, in particular, at least substantially absorbs the weight of the placement unit in at least one operating state, and in particular additionally at least substantially absorbs the weight of the items (in particular food) located on the placement unit, and at least substantially transmits the absorbed weight to the body. In particular, the support unit establishes a connection between the food resting unit and the body in at least one operating state. For example, the support unit may also be constructed separately from the food resting unit and/or from the body. Alternatively or additionally, the support unit may be at least partially integrally constructed with the food resting unit and/or with the body. In this case, "at least partially integrally" is to be understood in particular as meaning: at least one component of the at least one object and/or of the at least one first object is constructed integrally with at least one component of the at least one further object and/or is constructed integrally with the at least one further object.

In at least one operating state, the support unit at least substantially prevents the food placement unit from tipping over, in particular. Due to the support by the support unit, the main extension plane of the resting unit encloses a minimum angle of in particular at most 15 °, in particular at most 10 °, advantageously at most 5 °, particularly advantageously at most 3 ° and preferably at most 1 ° with a horizontal plane which is oriented in particular at least substantially parallel to the ground surface and/or parallel to the lower side of the appliance body and/or parallel to the upper side of the appliance body. The ground surface may be, in particular, a ground surface (in particular a floor and/or a lying surface which may be, in particular, formed at least partially by a ground surface). A "main plane of extension" of an object is to be understood in particular as a plane: the plane is parallel to the largest side of the smallest imaginary cube which exactly still completely encloses the object and extends in particular through the center of the cube. In this context, "substantially parallel" is to be understood to mean, in particular, an orientation of a direction relative to a reference direction (in particular in a plane), wherein the direction has a deviation relative to the reference direction of, in particular, less than 8 °, advantageously less than 5 °, and particularly advantageously less than 2 °.

For example, the support unit may be disposed at the rear of the body with reference to the depth direction. The support unit may for example be arranged on the rear wall of the body. The depth direction is in particular oriented at least substantially perpendicularly to the rear wall of the body. In particular, the depth direction is directed in the direction from the appliance door toward the rear wall of the appliance body in at least one operating state. The expression "substantially perpendicular" is intended here to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction (in particular viewed in a plane) enclose an angle of 90 ° and the angle has a maximum deviation of, in particular, less than 8 °, advantageously less than 5 °, and particularly advantageously less than 2 °. Advantageously, the support unit is arranged laterally of the body with reference to the horizontal direction. In particular, the support unit is arranged on at least one side wall of the body. The horizontal direction is especially oriented at least substantially perpendicular to the side walls of the body. The horizontal direction is especially oriented at least substantially parallel to the ground surface and/or parallel to the lower side of the body and/or parallel to the upper side of the body and/or parallel to the rear wall of the body.

"mounted in a manner such that the height can be adjusted in a stepless manner" is to be understood in particular as: the support unit is provided for: allowing the resting unit to move at arbitrarily large and/or small intervals. Advantageously, the resting unit can occupy a fixed position after the end of the movement, independently of the size of the space. Preferably, the movement is performed vertically. Advantageously, the movement can be achieved by moving the resting unit by the operator. However, it is also conceivable to provide the movement by means of a motor unit (in particular by means of an electric motor).

"coupling element" is to be understood to mean, in particular, an element that: the element mechanically and/or electrically couples at least two objects to each other. In particular, the coupling element provides a coupling with the resting unit. Advantageously, the first coupling element is arranged on a first side of the resting unit. Particularly advantageously, the second coupling element is arranged on a second side of the placement unit opposite the first coupling element. These coupling elements can be connected to the food placement unit, for example, by means of at least one thread and/or at least one weld seam and/or at least one adhesive layer and/or at least one snap-on connection and/or by means of another device which appears to be relevant to the person skilled in the art. In particular, the coupling elements absorb at least a portion of the weight of the resting unit and transmit it to at least one further unit (in particular a further unit of the support unit). Furthermore, these coupling elements can be designed in particular as damping elements, which are provided in particular for: the resting unit is braked and/or damped during its movement.

A "synchronization unit" is to be understood to mean, in particular, a unit that: the unit at least substantially transmits the movement of the first coupling element relative to the placement unit in at least the operating state to a corresponding movement of the second coupling element relative to the placement unit. In at least one installation state, the synchronization unit contributes in particular to the kinematic coupling of the first coupling element with the second coupling element.

"provided" is to be understood in particular as specially programmed, configured and/or equipped. A function that an object is provided with for determining should be understood in particular as: the object carries out and/or implements the determined function in at least one application state and/or operating state.

It is also proposed that the body is designed as an appliance body and defines a receiving chamber for the placement of the unit. "appliance body" is to be understood in particular as a body: the body constitutes at least 70%, advantageously at least 80% and particularly advantageously at least 90% of the outer casing of the household appliance. Advantageously, the appliance body and the appliance door together form an outer boundary (in particular a housing), advantageously a household appliance housing, in at least one operating state. Particularly preferably, an "appliance door" is understood to mean a unit: the unit is movable in at least one installation state and is connected to the appliance body, in particular pivotably relative to the appliance body, and forms part of an outer boundary (in particular a housing, advantageously a household appliance housing), in particular in the operating state. In particular, the appliance body has at least two side walls, at least one rear wall, preferably at least one upper side and at least one lower side, which together with the appliance door enclose the receiving space in at least one operating state. Furthermore, the body may define a receiving chamber for the support unit. In particular, the placement unit is arranged inside the receiving chamber. The placement unit has in particular an at least substantially plate-like form. It is also conceivable that the body defines receiving chambers for a plurality of supporting units and/or a plurality of resting units. This makes it possible to effectively utilize the installation space.

It is furthermore proposed that the body can be configured as an appliance door body and that the food resting unit can be configured as a door shelf. "appliance door body" is to be understood in particular as a body: the body constitutes at least 70%, advantageously at least 80% and particularly advantageously at least 90% of the outer casing of the appliance door. In particular, the appliance door is in the closed state in the operating state. Furthermore, the placement unit is arranged in the operating state inside the receiving chamber.

In particular, the body may define a receiving chamber for the resting unit. Furthermore, the body may define a receiving chamber for the support unit. Furthermore, the body may define receiving chambers for a plurality of support units and/or a plurality of resting units. Preferably, the appliance door body defines a receiving surface for the resting unit. Furthermore, the body may define a receiving surface for the support unit. Furthermore, the body can define a receiving surface for a plurality of support units and/or a plurality of resting units. This makes it possible to achieve efficient use of installation space.

Furthermore, it is proposed that, in the operating state and during the height adjustment of the placement unit, the first center of gravity of the first coupling element and the second center of gravity of the second coupling element move together with the food placement unit. In particular, the coupling elements move together with the placement unit when the placement unit moves in the operating state. Preferably, the coupling elements move together with the placement unit when the placement unit moves vertically in the operating state. In particular, the first coupling element and the second coupling element move with the same dimension (Ma β e). Thereby, flexibility can be improved. In particular, the coupling of the placement unit to the support unit can be ensured for a plurality of positions of the placement unit.

In one embodiment, it is provided that the first coupling element and the second coupling element are designed as rolling elements, which are each configured to adjust the height of the placement unit in the operating stateRolling on the rolling rod of the supporting unit. These rolling bars have in particular an at least substantially rod-shaped form. The term "rod-shaped form of an object" is to be understood in particular as meaning: the object has a longitudinal extension (

) The longitudinal extension is at least 5 times, in particular at least 10 times, advantageously at least 20 times, particularly advantageously at least 30 times and preferably at least 50 times the extension of the object perpendicular to the longitudinal extension. In particular, these rolling bars extend along the entire movement path of the resting unit defined by the supporting unit. Advantageously, these rolling levers are connected to the body. In particular, in each case at least one rolling bar is arranged on opposite sides of the appliance body. Alternatively, the roll bars are arranged on one side of the appliance door body. In particular, the vertical movement of these rolling elements generates its own rotational movement. These rolling elements are configured, for example, as balls and/or rings and/or wheels. This can improve the operating comfort. In particular, a simplified movement of the placement unit can be achieved.

In a further embodiment, it is provided that the rolling elements are in the form of toothed wheels and the rolling bars are in the form of toothed racks, the toothed wheels and toothed racks meshing with one another in the operating state. A "toothed rack" is to be understood in particular as a unit: the units have at least substantially a rod-like pattern and a (in particular regular) arrangement with the teeth. The teeth can be connected to the toothed rack in a form-fitting manner. Preferably, the teeth are embodied integrally with the toothed rack. "engaging" is to be understood as: the teeth of the rolling elements engage in the spaces between the teeth of the rolling bars. In particular, this engagement creates its own rotational movement during the vertical movement of the rolling element. This can improve the firmness. In particular, a fixed coupling of the food resting unit with the supporting unit is achieved by the engagement.

Furthermore, it is proposed that the synchronization unit has at least one connection unit which, in the operating state, mechanically couples the first coupling element to the second coupling element. "mechanically coupled" is to be understood in particular as meaning an operative connection: the functional link is composed entirely of at least one solid. In particular, the connecting unit may be arranged on the resting unit. Preferably, the connection unit is arranged on a lateral area of the food resting unit. Alternatively, the connection unit may be disposed on the body. In particular, the connecting unit is connected to the coupling element in a form-fitting manner. For example, the connection unit is connected to the coupling element by means of at least one thread and/or at least one weld seam and/or at least one adhesive layer and/or at least one snap-fit connection and/or other means which appear to be expedient to the person skilled in the art. Thereby a simple structure can be realized. In particular, the transmission of the movement of the coupling element to the other coupling elements can be achieved by a simple construction.

Furthermore, it is proposed that the connecting unit transmits the rotational movement of the first coupling element to the second coupling element in the operating state and during the height adjustment of the food placement unit. In particular, the rotational movement of the first coupling element is different from the rotational movement of the second coupling element generated by the transmission. Preferably, the rotational movement of the first coupling element coincides with the rotational movement of the second coupling element. For transmitting the rotational movement, the connection unit can have, for example, at least one gear and/or at least one connecting rod. This can improve the operating comfort. In particular, the operator can rotate the second coupling element by rotating the first coupling element in the same way without additional operating effort.

It is additionally proposed that the connecting unit can have at least one stabilization rod which, in the operating state, participates in the mechanical coupling of the first coupling element with the second coupling element. In particular, the stabilizer bar is disposed on the placement unit. The stabilizer bar in particular has a longitudinal extent which is at least 5 times, in particular at least 10 times, advantageously at least 20 times, particularly advantageously at least 30 times and preferably at least 50 times the extent of the synchronization element oriented perpendicular to this longitudinal extent. The stabilizing rod can be connected with the placing unit in a shape-locking manner. Preferably, the stabilizing bar is integrated into the resting unit. Advantageously, the stabilizer bar has a rod-like form. In a particularly advantageous manner, during the height adjustment of the placement unit, a torque is transmitted via the stabilizer bar, which causes a rotational movement of the stabilizer bar about its longitudinal axis. It is conceivable that the stabilizer bar produces an integral mechanical coupling of the first coupling element with the second coupling element. In particular, the stabilizer bar is connected in a form-locking manner to at least one of the coupling elements. Preferably, the stabilizer bar creates a part of the mechanical coupling of the first coupling element with the second coupling element. Particularly preferably, the stabilizer bar is operatively connected to at least one of these coupling elements. This can improve the firmness. In particular, a stable coupling of these coupling elements can be achieved.

Furthermore, it is proposed that the stabilizer bar is arranged on a lateral region of the placement unit. In particular, the stabilizing bar can be arranged on that lateral region of the resting unit which faces the operator. Preferably, however, the stabilizing bar is arranged on that lateral region of the resting unit which faces away from the user. A high level of operating comfort can thereby be achieved. In particular, a visually attractive configuration of the synchronization unit can be avoided. In addition, the installation space can be effectively utilized. Advantageously, it is possible to avoid that an article arranged below the resting unit comes into contact with the synchronization unit.

In a further embodiment, it is provided that the connecting unit has at least one traction means drive (Zugmitteltrieb) which mechanically couples the first coupling element with the stabilizer bar. In particular, the connecting unit can have at least one further traction means drive which mechanically couples the second coupling element with the stabilizer bar. It is conceivable for the traction means of the traction means drive to surround the first coupling element and the stabilizer bar. The traction means can in particular have at least one belt and/or at least one toothed belt and/or at least one chain. Advantageously, the traction means surrounds the first coupling element, the stabilizer bar and the at least one tensioning unit. A "tensioning unit" is to be understood in particular as a unit: the unit is provided for adjusting the tension of the traction means. In particular, the tensioning unit has at least one tensioning wheel. The tensioning wheel can be designed in particular as a roller and/or a gear. In particular, the tensioning wheel has at least one spring element, which exerts a spring force on the tensioning wheel. This makes it possible to realize a simple structure. In particular, the mechanical coupling of the first coupling element with the stabilizer bar can be achieved with a small number of components. Advantageously, a simple mounting and dismounting of the coupling of the first coupling element with the stabilizer bar is achieved.

It is also proposed that the placement unit has a blanking unit (blendenelheit) which at least partially covers the synchronization unit. In particular, the shielding unit completely covers the synchronizing unit. "partially covering" is to be understood in particular as: at least for a part of the synchronization unit, a shielding unit is arranged between a part of the synchronization unit and an observer outside the resting unit. The shielding unit may be at least partially integrally formed with the placement unit. Preferably, the screen unit is connected to the placement unit in a form-fitting manner. In particular, the screen unit is connected to the placement unit by means of at least one thread and/or at least one weld and/or at least one adhesive layer and/or at least one snap-fit connection and/or other means which appear to be relevant to the person skilled in the art. This can improve the operating comfort. In particular, the visual aspect of the synchronization unit can be reduced. Advantageously, the synchronization unit can be integrated into a full range of devices (Garnitur) of the shelving unit.

By the expressions "upper", "lower", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" and the like, positions and orientations are explained which result when the food resting unit or appliance is used and arranged according to regulations.

Detailed Description

Fig. 1 shows an exemplary embodiment of a household appliance 10a in an operating state. The household appliance 10a is configured as a household refrigeration appliance (in particular a refrigerator and/or freezer). The household appliance 10a has a household appliance device 12a (here a household refrigeration appliance device). The household appliance device 12a has a body 14 a. The body 14a is configured as an appliance body 84 a.

The body 14a at least partially delimits a refrigeration chamber (not shown). The refrigeration compartment (which may also be referred to as a food compartment) is designed, for example, as a cold storage compartment (or freezer compartment). Alternatively, the refrigeration chamber may also be configured as a freezer compartment (or freezer compartment). The household appliance device 12a has an appliance door 16 a. The appliance door 16a is swingably supported with respect to the appliance body 84 a. In the operating state, the appliance door 16a closes the refrigeration compartment.

Inside the refrigerating chamber, a resting unit or food resting unit 18a (see fig. 2) is arranged. The placement unit 18a can be a component of the household appliance device 12 a. The resting unit 18a has a substantially plate-like form and therefore has in particular a resting plate 110 a. In the exemplary embodiment shown here, the placement unit 18a is designed as a shelf. The placement unit 18a is provided for storing food. In the operating state, food (not shown) is arranged on the resting unit 18 a. The placement unit 18a is fixed to the body 14a in the operating state. The body 14a also defines a receiving chamber for resting the unit 18 a.

The household appliance device 12a has a bearing unit 20a (see fig. 2 to 4). The supporting unit 20a supports the placement unit 18a on the body 14a in an operating state in a manner such that the height can be adjusted steplessly. The support unit 20a horizontally supports the placement unit 18a in the operating state. The support unit 20a has a first holding rail 30 a. The support unit 20a has a second holding rail 74 a. The placement unit 18a has a first carrier unit 68 a. The placement unit 18a has a second carrier unit 70 a. These carrier units 68a, 70a are configured as tees. These carrier units 68a, 70a engage in the retaining

rails

30a, 74a and prevent the resting unit 18a from tipping over. The support unit 20a defines a vertical movement track. The placement unit 18a is movably supported along a vertical movement path. The vertical direction is oriented substantially perpendicular to the lower side of the body 14a and/or perpendicular to the main extension plane of the resting unit 18 a.

The support unit 20a has a first coupling element 22 a. The support unit 20a has a second coupling element 24 a. These

coupling elements

22a, 24a are designed as rolling

elements

92a, 94a (in particular as

toothed wheels

96a, 98 a). These

coupling elements

22a, 24a are arranged on opposite sides of the placement unit 18 a. The

coupling elements

22a, 24a are connected to the placement unit 18a in a form-fitting manner. The center of gravity 88a of the first coupling element 22a and the center of gravity 90a of the second coupling element 24a move together with the placement unit 18a in the operating state and during a movement of the placement unit 18 a.

The support unit 20a has a first rolling bar 28 a. The first roll-down lever 28a is only partially shown in fig. 3 in order to achieve a clearer view. The support unit 20a has a second rolling bar (not shown). The roll bar 28a is configured, for example, as a toothed rack 100a (in particular as a toothed rack). The rolling bar 28a is arranged parallel to the holding

rails

30a, 74 a. The roll bar 28a is fixed to the body 14 a. The roll bar 28a is fixed to the lateral inner wall of the body 14a (more precisely, in particular, in a recess of the lateral inner wall). The rolling bars 28a are arranged on opposite sides of the resting unit 18 a. In the operating state and when the placement unit 18a is moved, the

coupling elements

22a, 24a each roll on one of the rolling levers 28 a. The rolling bar 28a engages with the

coupling elements

22a, 24a in the operating state.

In this embodiment, the support unit 20a has a synchronizing unit 26 a. The synchronization unit 26a is designed separately and independently from the placement unit 18a, said synchronization unit 26a being a component of the adjustment device. The synchronization unit 26a is arranged on the placement unit 18 a. The synchronization unit 26a transmits the movement of the first coupling element 22a relative to the placement unit 18a in the operating state and upon movement of the placement unit 18a at least substantially via a lateral region of the placement unit 18a into a corresponding movement of the second coupling element 24 a. The synchronization unit 26a has a connection unit 32 a. The connecting unit 32a mechanically couples the first coupling element 22a to the second coupling element 24a in the operating state. The connecting unit 32a transmits the rotational movement of the first coupling element 22a to the second coupling element 24a in the operating state and upon movement of the placement unit 18 a.

In this embodiment, the connection unit 32a has a stabilizer bar 34 a. The stabilizer bar 34a is disposed on a lateral region of the placement unit 18 a. The stabilizing bar 34a is arranged on the side of the placement unit 18a facing away from the user and on the rear narrow edge 102a of the placement unit 18 a. In particular, the stabilizing bar 102a is arranged completely within the height h of the resting unit 18 a. The stabilizer bar 34a participates in the mechanical coupling between the first coupling element 22a and the second coupling element 24a in the operating state.

Preferably, the connection unit 32a has a traction means drive 36 a. The traction means drive 36a has in particular a traction means 38 a. The pulling means 38a is configured, for example, as a pulling strap. Alternatively, the traction means 38a can also be constructed as a chain. The traction means drive 36a has two tensioning

wheels

40a, 42 a. The traction means drive 36a preferably has a tensioning bracket 44 a. The

tensioning wheels

40a, 42a and the tensioning bracket 44a serve to adjust the tensioning of the traction means 38 a. The traction means transmission 36 mechanically couples the first coupling element 22a with the stabilizer bar 34 a. The traction means 38a surrounds the first coupling element 22, the

tensioning wheels

40a, 42a, the tensioning bracket 44a and the stabilizer bar 34 a. Furthermore, the connecting unit 32a has a further traction means drive (not shown), which couples the second coupling element 24a preferably with the stabilization bar 34 a. The further traction means drive is in particular designed in accordance with the traction means drive 36 a.

The placement unit 18a preferably has a shielding unit 46 a. The shielding unit 46a is configured as a cover member. Alternatively, the shielding unit 46a may be configured as a complete equipment. The shielding unit 46a is arranged on the side of the placement unit 18a facing away from the user and therefore in particular on the rear side. The shielding unit 46a covers the synchronizing unit 26a at least partially. In particular, the shielding unit 46a covers the stabilizer bar 34 a. In order to be able to better see the further unit, the partial region of the shielding unit 46a covering the stabilization bar 34a is therefore not shown in fig. 2.

The support unit 20a has, in particular, a contact unit 48a (see fig. 4). The contact unit 48a has a first contact element 50a and a second contact element 52 a. These

contact surface elements

50a, 52a are in particular designed as sliding contacts (Schleifkontakte). These

contact surface elements

50a, 52a are arranged on the second holding rail 74 a. The contact unit 48a has a first further contact element (not shown) and a second further contact element (not shown). The two further contact surface elements are arranged on the first holding rail 30 a. These two further contact elements are formed in accordance with the

contact elements

50a, 52a, so that only the

contact elements

50a, 52a will be explained in the following. The first contact surface element 50a is preferably embodied as a positive electrode. The second contact surface element 52a is preferably configured as a negative electrode. These

contact surface elements

50a, 52a preferably extend over the entire path of movement of the placement unit 18a, which is defined by the support unit 20 a.

The contact unit 48a has a first sliding contact element 54a (see fig. 3 and 5). The contact unit 48a has a second sliding contact element 58 a. These sliding

contact elements

54a, 58a are designed as electrically conductive spring pins. These sliding

contact elements

54a, 58a are arranged on that side of the first carrier unit 68a which faces the first holding rail 30 a. The contact unit 48a has two further sliding contact elements (not shown). These further sliding contact elements are arranged on that side of the second carrier unit 70a which faces the second holding rail. These further sliding contact elements are constructed in accordance with the above-described sliding

contact elements

54a, 58a, so that only these sliding

contact elements

54a, 58a will be explained in the following. The first sliding contact element 54a has a first housing 76 a. The second sliding contact element 58a has a second housing 78 a. These

housings

76a, 78a are designed as electrically conductive hollow cylinders. The first sliding contact element 54a has a first elastic element 56 a. The second sliding contact element 58a has a second elastic element (not shown). These elastic elements 56a are configured as spring elements. The resilient elements 56a are partially received by the

shells

76a, 78 a. These elastic elements 56a are arranged in the recesses of the first carrier unit 68 a. These elastic elements 56a provide a pressing force for pressing onto the two further contact surface elements. The first spring element 56a presses the first housing 76a against the first further contact surface element in the operating state. The second spring element presses the second housing 78a against the second further contact surface element in the operating state.

In all operating-suitable positions of the placement unit 18a and during movement of the placement unit 18a, the contact unit 48a preferably provides an electrical energy transmission between the body 14a and the placement unit 18 a. For this purpose, the

shells

76a, 78a slide over the

contact surface elements

50a, 52a when the placement unit 18a is moved relative to the body 14 a.

At a position which meets the operating requirements (

Stellung), the preferably existing contact unit provides preferably two electrically parallel transmission channels for the transmission of electrical energy between the body 14a and the resting unit 18 a. The first transfer channel is provided by the sliding of these

shells

76a, 78a on the above-mentioned further interface elements when the resting unit 18a is moved relative to the body 14 a. A second transmission channel is provided by the sliding of the further housings of the further sliding contact elements on the

contact element elements

54a, 58a when the resting unit 18a is moved relative to the body 14 a.

Preferably, the placement unit 18a has a functional unit 62a, which functional unit 62a is only shown in a simplified manner in fig. 4. The function unit 62a has a user interface. The user interface has an operation unit 72 a. The operating unit 72a is arranged on the side of the placement unit 18a facing the user in the depth direction (z direction). Preferably, the operating unit 72a has a first pressure switch and a second pressure switch. The operating unit 72a is connected to the clamping element via an electrical line. When the user actuates the first pressure switch, a first signal is transmitted by the operating unit 72a to the clamping elements, which thereby fix the placement unit 18 a. When the user actuates the second pressure switch, a second signal is transmitted by the operating unit 72a to the clamping elements, which release the fastening of the placement unit 18 a.

Preferably, the function unit 62a has a sensor unit. The sensor unit has an optical sensor 80 a. The optical sensor 80a is disposed in the vicinity of the operation unit 72 a. The optical sensor 80a is configured as a camera. The optical sensor 80a is provided for: information about the items (in particular food) located on the resting unit 18a is collected.

The sensor unit has a temperature sensor 64 a. The temperature sensor 64a is arranged in the vicinity of the optical sensor 80 a. The temperature sensor 64a is configured as a thermal element. Alternatively, the temperature sensor 64a may also be configured as an NPC sensor and/or as a PTC sensor. The temperature sensor 64a is provided for: information on the temperature aspect of the resting unit 18a is collected.

The sensor unit has a sensor 66a for detecting the occupancy of the placement unit 18a by an item, in particular a food item. The sensor 66a is configured as a force sensor. The sensor 66a is configured as a membrane. The sensor 66a extends over the entire bearing surface of the placement unit 18 a. The sensor 66a is arranged to: information is collected about the weight of the items located on the resting unit 18 a. For this purpose, the sensor 66a measures the weight force acting on the resting unit 18 a.

Preferably, the contact unit 48a provides data transmission between the body 14a and the functional unit 62a in the operating state. Thus, the information collected by the sensor unit may be further transmitted to the user, for example, through a terminal located on the body 14 a.

While the further explanation is particularly applicable to different, further examples, according to the examples of fig. 1 to 4.

The bearing unit 20a has a rolling bar 28a, which rolling bar 28a is provided externally with respect to the food placement unit 18a and is therefore not an integral part of the food placement unit 18 a. Furthermore, the support unit 20a has an adjusting device 108 a. The adjusting device 108a is an integral part of the food resting unit 18 a. Thus, the adjustment device 108a is arranged directly on the food resting unit 18 a.

In particular, the adjustment device 108a has a connection unit 33a and also a synchronization unit 26 a. The adjustment unit 108a also has a motor drive unit 60a (fig. 3). The motor-driven unit 60a is arranged in a stationary manner on the food placement unit 18 a. In this embodiment, the motor drive unit 60a is disposed on the rear narrow edge 102a of the resting plate 110a as viewed in the depth direction (z direction). Preferably, a fitting cavity 112a is configured on the rear narrow edge 102 a. The assembly recess 112a is delimited (in particular circumferentially delimited) by the shielding element 46 a. In the fitting cavity 112a, a motor drive unit 60a is disposed. In particular, at least one component of the synchronization unit 26a is also mounted there.

In fig. 3, which is only schematically illustrated, the food placement unit 18a has a sliding coupling 118a, which sliding coupling 118a is an integral part of the adjusting device 108 a. The sliding coupling 118a is arranged directly adjacent to the motor drive unit 60a and is coupled thereto. Furthermore, the slip linkage 118a is coupled to the synchronization unit 26 a.

As can be seen, the resting plate 110a has a height h. The motor drive unit 60a and the slip coupling 118a are arranged completely within the height h. In particular, all components of the adjusting device 108a are arranged completely within the height h.

As can also be seen in fig. 3, the resting plate 110a has a further narrow edge 104a, which further narrow edge 104a is a lateral narrow edge and extends in the depth direction. Here too, a mounting pocket 114a is formed, in which mounting pocket 114a the components of the connection unit 32a are arranged, as already explained above. A coupling element 22a is also arranged there, which coupling element 22a, in its function as a gear wheel, directly rolls (or meshes) with a toothed ring and in particular a toothed rack on a rolling bar 28a, as is shown in fig. 3.

The placement plate 110a is shown partially in fig. 4 and from the side opposite to fig. 3. Here too, a further lateral narrow edge 106a is shown, in which further lateral narrow edge 106a corresponding configuration of the adjustment unit 32a is formed, as is shown in fig. 3. These

narrow edges

104a and 106a constitute second and third narrow edges of the resting plate 110 a. A mounting pocket 116a is also formed on this narrow edge 106a extending in the depth direction, in which mounting pocket 116a the corresponding components of the connection unit 32a are correspondingly mounted, as is shown in fig. 3 in the mounting pocket 114 a.

A further embodiment of the invention is shown in fig. 6. The following description and the figures are substantially limited to the differences between the exemplary embodiments, wherein, with regard to identically numbered component aspects (in particular with regard to component aspects having the same reference numerals), substantially further exemplary embodiments (in particular the figures and/or the description of fig. 1 to 5) can also be referred to. To distinguish between these embodiments, the letter a is placed after the reference numerals of the embodiments in fig. 1 to 5. In the embodiment of fig. 6, the letter a is replaced by the letter b.

Fig. 6 shows a further household appliance 10b with an alternative household appliance device 12 b. The body 14b is configured as an appliance door body 82b of an appliance door 16b of the household appliance device 12 b. In the present illustration, appliance door 16b is open. The support unit 20b is disposed on an inner wall of the body 14 b. The supporting unit 20b supports the placement unit 18 b. The food resting unit 18b is configured as a door shelf 86 b. The placement unit 18b has a drive unit 60b, which drive unit 60b is only shown in a simplified manner in fig. 6. The drive unit 60b is arranged on the side of the placement unit 18b facing away from the user, viewed in the depth direction (z direction). Preferably, the drive unit 60b has an electric motor as the motor-type drive unit 60 b. The drive unit 60b is provided for moving the resting unit 18b with respect to the body 14 b. Preferably, the contact unit (not shown) provides the electrical energy supply of the drive unit 60b in the operating state. The driving unit 60b causes a rotational movement of a stabilizer bar (not shown) upon receiving a signal. This enables a movement of the placement unit 18b in the height direction (y direction) and thus a height adjustment.

In the embodiment in fig. 6, the motor-driven unit 60b is also arranged on the rear narrow edge 102b of the food resting unit 18b, as this is schematically indicated in fig. 6. In this embodiment, the household appliance device 12b has, in addition to the food resting unit 18b, door beams (T ü rholme) on which the food resting unit 18b can be adjusted continuously in height. Instead of the door beam, side walls of the appliance door 16b can also be provided, as is shown in fig. 6, which side walls 16b can also be components of a household appliance.

In the embodiment according to fig. 1 to 4, the

side walls

118b and 120b of the household appliance component shown in fig. 6 can be provided as a component of the

household appliance device

12a, 12 b.

Fig. 7 shows a perspective partial view of a further exemplary embodiment of a food placement unit 18 c. The food placement unit 18c is also preferably designed here as a shelf with a placement plate 110c (or as just one such placement plate).

The configuration of the food resting unit 18c corresponds here to the configuration in fig. 2 to 4. Here, a motor-driven drive unit 60c is arranged on the rear narrow edge 104 c. Likewise, a sliding coupling 118c is provided. The motor-driven drive unit 60c is coupled with the synchronization unit 26c via a sliding coupling 118c (in particular via coupling elements in the form of, for example, gears 122c and 124 c). The adjusting device 108c shown here again has a connecting unit 32c, which connecting unit 32c functions functionally in accordance with the connecting unit 32a and can be additionally designed in a component-specific and position-specific manner if necessary.

Coupling element 22c and pulling means 38c are also shown here. These components are arranged in the lateral fitting cavities 114 c.

In the exemplary embodiment shown, not only the motor drive unit 60c but also two separate motor drive units 60c are arranged in the assembly recess 112c on the rear side. Accordingly, two separate independent sliding couplings 118c are also preferably provided. In particular, the further motor drive unit 60c is also coupled to the synchronization unit 26c via further coupling elements (in particular the

gears

122c and 124 c). On the opposite narrow edge opposite the lateral narrow edge 104c in the width direction (x direction), a connecting unit 32c is provided in the corresponding configuration. Such a synchronization unit 26c is preferred in order to synchronize the coupling of the adjustment units 32c and in particular the movement of the coupling element 22c and the opposite, not shown, further coupling element.

In fig. 8, an enlarged view of the food resting unit 18c in fig. 7 is shown. Here, it can also be seen that the fitting cavity 114c is covered by a lateral cover 126 c. Here, the slide coupling 118c is actually shown in an open state. Two

shafts

128c and 130c are shown, the shafts being shown in a coupled state. The

shafts

128c and 130c are coupled by the slide coupling 118c, so that the motor driving force in the form of the motor-driven unit 60c is transmitted to the synchronizing unit 26c via the

gears

122c and 124 c.

The food resting unit 18c is shown in perspective in its entirety in fig. 9. As can be seen here, in a further embodiment, a plurality of (in particular more than) two motor drive units 60c can also be provided.

In the illustrated embodiment, these components are all mounted in the assembly cavity 112 c. The opposing narrow edge 106c is also shown in fig. 9. In particular, a mounting pocket 116c is provided there, which mounting pocket 116c can likewise be covered by a cover 126 c.

Fig. 10 shows a perspective partial view of a further exemplary embodiment of a food placement unit 18 d. Here, the food resting unit 18d may also have (or be) a resting plate 110 d. In this embodiment, it is provided that the motor drive unit 60d is not mounted in the rear narrow edge on the rear, but on the lateral narrow edge 104 d. Here, a lateral assembly recess 114d is also preferably formed, in which assembly recess 114d a motor drive unit 60d is mounted. In particular, the sliding coupling 118d is also coupled here to the motor drive unit 60 d. In this embodiment, provision is made for the adjusting device, in addition to the components mentioned (i.e. motor drive unit 60d, sliding coupling 118d, coupling element 22d), not to have a traction means with a traction means gear mechanism (as is the case in the above-mentioned example), but rather to have a worm gear 132 d. The worm gear 132d has (as can be seen in the illustration of the detailed description in fig. 11) a worm shaft 134d and a worm wheel 136 d. In particular, a corresponding configuration is also provided on the opposite lateral narrow edge 106 d. The two separately independent motor drive units 60d are preferably synchronized via a synchronization unit, which is not shown here and can be mounted, for example, in a fitting cavity in the rear narrow edge of the rear face, in particular. In particular, this synchronization is achieved via the synchronization of the rotational speeds of the motor drive unit 60 d.

Fig. 11 shows an exemplary button 138d, by means of which button 138d the height adjustment process can be activated. For example, the user can actuate the button 138d, so that the motor drive unit 60d is subsequently activated in order to carry out the height adjustment process. In the configuration in fig. 10 and 11, a cover 126c may also be provided. As can be seen in fig. 10 and 11, the assembly recess on the rear side is covered by a cover 140. Preferably, all the sliding couplings mentioned are constructed according to the design explained for fig. 8.
