Disclosure of Invention

The object of the present invention is to provide an improved domestic refrigerator having a weighing device.

The object of the invention is achieved by a domestic refrigeration device having: an insulated housing having an inner container bounding a coolable interior space configured for storing food; a cooling device for cooling the coolable interior space; a weighing device; and a placement surface for placing food, the placement surface comprising the weighing device, which in turn comprises a plurality of individual (individudelle) weighing cells, which each have a weighing surface and are arranged directly adjacent to one another, such that the weighing surfaces of the individual weighing cells jointly span a weighing zone, which at least partially constitutes the placement surface.

The domestic refrigeration appliance according to the invention comprises a thermally insulated housing with an inner container which delimits the coolable interior. The interior space is cooled by means of a refrigerating device. The refrigerating device is preferably designed as a refrigerant circuit, which is known in principle to the person skilled in the art, and is preferably designed such that it cools the coolable interior at least approximately to a predetermined temperature. The coolable interior space is configured to store food.

The domestic refrigeration appliance according to the invention is in particular a domestic refrigeration appliance, the coolable interior of which is cooled to a temperature of more than 0 ℃.

The domestic refrigerator according to the invention furthermore comprises a placement surface for placing food. The placement surface comprises a weighing device. The weighing device comprises a plurality of individual weighing cells, which each have a weighing surface and are arranged directly adjacent to one another, so that the weighing surfaces of the individual weighing cells jointly span a weighing region, which at least partially forms the placement surface.

The weighing device comprises individual (or separate) weighing cells which jointly span (or form) a weighing area or weighing array, whereby the weighing device does not weigh all food items stored on the weighing area as a whole, but individual food items stored on the weighing area in individual part areas corresponding to the separate weighing cells. For example, this achieves: the individual foods stored on the weighing area are differentiated or the mass of the individual foods is individually detected. In the conventional case, a single weighing cell does not detect the total mass of the food items stored on the weighing area, but only a partial mass in the case of stored food items extending over a plurality of weighing cells of the weighing device. According to the invention, not only the total mass of the food items stored on the weighing region but also the mass of a plurality of food items stored on the weighing region can be determined individually, in such a way that the use is significantly simplified for the user and is application-friendly. For the evaluation of the signals generated by the individual weighing cells, the weighing device can be connected to an electronic evaluation device of the domestic refrigeration appliance. The electronic evaluation device can also be arranged outside the domestic refrigeration appliance according to the invention. Furthermore, for recognizing the food and in particular for detecting the physical size of a plurality of food items simultaneously stored on the weighing area of the weighing device, an optical sensor (e.g. a camera) or another suitable sensor can be provided, which can be connected to an evaluation device provided outside or inside the domestic refrigeration appliance according to the invention for processing data. According to the invention, the weighing device in particular forms a self-contained weighing area which is particularly user-friendly for the user, by means of an essentially continuous or gap-free arrangement of a plurality of weighing cells in the weighing area or by means of an arrangement of a plurality of individual weighing cells directly adjacent to one another.

The expression "open" is also to be understood as meaning "defined" or "formed" within the meaning of the present invention. In the sense of the present invention, this is understood as: the weighing device consists of a plurality of individual weighing cells or weighing cells which are arranged in defined regions or areas and which are perceived by the user as a coherent and self-integrating weighing region.

The expression "weighing zone" is also understood to mean, in the sense of the present invention, a "weighing array". In the sense of the present invention, a "weighing area" is understood to be an area or region in which: a plurality of individual weighing cells or weighing cells are arranged directly adjacent to one another in the region or area.

The weighing device can be embodied as an assembly, which has, in particular, a trough-shaped carrier on which the individual weighing cells are arranged.

The domestic refrigeration appliance according to the invention can comprise a shelf bottom arranged in the coolable interior space for resting food. The bottom of the grid bottom may comprise a resting surface, which in turn comprises a weighing device. The weighing surfaces of the individual weighing cells of the weighing device jointly open a weighing region. The weighing region of the weighing device can form, in part or in large part, the resting surface of the compartment bottom or even the entire resting surface of the compartment bottom. In the case of a shelf at the bottom of the compartment, the rest of the bottom can be made of glass, with the weighing device being provided in part on the resting surface. The shelf surface of the shelf/storage base can comprise a circumferential, injection-molded frame, on which fastening means can be provided for fastening the storage base to the inner container of the domestic refrigeration appliance.

It can be provided that the weighing device is embodied as a component which is fastened to the bottom of the storage base, or that the weighing device is integrated into the bottom of the storage base.

It can be provided that the bottom of the storage base is constructed continuously and the module is fastened to the base, or that the module is arranged in an opening in the bottom of the storage base. The component is preferably arranged on that surface of the placement surface which faces the food stored on the placement surface. Naturally, it can also be provided on that surface of the resting surface which faces away from the food stored on the resting surface.

It may be provided that the storage base is the base of a drawer.

The following specific configuration, although directed in particular to a door shelf, is possible and not excluded by the invention, as is the use of the following specific configuration of the weighing device in a storage base or drawer of a domestic refrigeration appliance according to the invention.

According to a preferred embodiment of the domestic refrigeration device according to the invention, the domestic refrigeration device has a door leaf which has a side facing the coolable interior and is provided for: the coolable interior space is closed in the closed state and made accessible in the open state. The domestic refrigeration appliance preferably comprises a door shelf which is arranged on the side of the door leaf facing the coolable interior and comprises the weighing device and a bottom, wherein the bottom of the door shelf forms a placement surface for placing food and the individual weighing cells are arranged directly next to one another such that the weighing surfaces of the individual weighing cells jointly form a weighing region.

The weighing device can be connected to an electronic evaluation device of the domestic refrigerator, which evaluates the signals generated by the weighing device. The weighing device can be electrically contacted, in particular for supplying it with electrical energy, or for communicating with an evaluation device, which is arranged, for example, in the door leaf or in the thermally insulated housing, for example, in that the weighing device has an electrical plug connection which is coupled to a mating electrical plug connection arranged on the door leaf.

The weighing device comprises a single (or individual) weighing cell, whereby the weighing device does not weigh all food items resting on the resting surface (in particular not all food items stored in the door shelf) as a whole, but only single food items stored in a single part area of the resting surface corresponding to these individual weighing cells (or in a single part area of the door shelf corresponding to these individual weighing cells). This achieves, for example: the foods stored on the resting surface (or in the door shelf) are differentiated or the quality of these foods is individually detected.

The individual weighing cells are preferably arranged in an array in the weighing region. In particular, the individual weighing cells are arranged closely and/or tessellately in the weighing region of the weighing device. Preferably, the individual weighing cells are substantially gapless relative to each otherAnd (4) arranging. In particular, it is provided that at least six weighing cells are oriented in the longitudinal direction of the door shelf

Arranged adjacently and at least two weighing cells are arranged adjacently transversely to the longitudinal orientation. Preferably, six weighing cells are arranged adjacently in the longitudinal orientation of the door shelf, and two weighing cells are arranged adjacently transversely to the longitudinal orientation.

For example, the area of the weighing surface of each of these weighing cells is, for example, 70mm x40 mm.

The individual weighing cells are preferably of rectangular design in order to keep the boundary region between two adjacent weighing cells as small as possible, so that the weighing surfaces of the individual weighing cells form a weighing region as free of interruptions (or continuously) as possible, and the regions which do not contribute to detection can be kept small.

The door shelf includes, for example, upwardly open containers. The container is made of plastic, for example.

The door shelf may have upwardly closed containers (e.g., made of plastic) that are accessible through lateral openings thereof. Such an embodiment of the door shelf (or container thereof) may have door leaves for opening and closing the lateral opening. The door shelf is preferably provided for storing butter.

According to one variant of the domestic refrigerator according to the invention, the weighing device is integrated into the bottom of the container.

According to a preferred embodiment of the domestic refrigeration appliance according to the invention, the weighing device is embodied as an assembly. The assembly can be produced in particular separately from the door shelf and, if necessary, can also be implemented in such a way that the door shelf can be subsequently retrofitted with a weighing device implemented as an assembly.

The weighing device embodied as an assembly is in particular fastened in a receptacle of a door shelf.

The component can be fastened to the container, in particular integrated into the door shelf, for example by force-fitting, form-fitting or material-fitting connection techniques, for example by insertion, snapping, gluing or welding.

The container may have, for example, a continuous bottom (i.e. a continuous downwardly directed wall) on which the assembly is fastened. In this case, the weighing device embodied as an assembly can be placed (or inserted) onto the bottom of the container. This makes it possible to subsequently add weighing devices embodied as modules to the door shelf.

Preferably, the container can be embodied such that the downwardly directed component part of the container is at least partially open. Furthermore, it can be provided that the container is embodied such that at least a major part of the downwardly directed components of the container is open. In this case, the component constitutes, partially or largely, the downwardly directed surface (or bottom) of the door shelf. The container according to this variant of the domestic refrigerator according to the invention has substantially no closed bottom (or no downwardly directed wall) and the downwardly directed surface of the door shelf is substantially formed by the component, so that the bottom of the entire door shelf is thinner than in the variant in which the container comprises a downwardly directed wall. Thus, the volume and lateral height of the door shelf with weighing means can be kept constant compared to a door shelf without weighing means, and the technical structure can be arranged or integrated into the bottom (or below the container bottom).

The assembly preferably comprises a basin-shaped carrier on which the individual weighing cells are arranged. The carrier is preferably embodied in one piece and comprises in particular fastening means for the individual weighing cells. In particular, substantially all of the component parts of the weighing device are arranged (or fastened) on a carrier, which is in particular configured as a carrier plate.

Preferably, the assembly is connected to the container of the door shelf by means of a carrier or the assembly is fastened to the container of the door shelf by means of a carrier.

Preferably, the upwardly directed face of the carrier (or carrier plate) is divided into a number of individual weighing faces, or into a number of individual receptacles for weighing cells, which correspond to individual weighing cells. These weighing surfaces can be individually adapted to the geometry of the resting surface or to the geometry of the door shelf.

Each weighing surface corresponds to a weighing cell, which in turn comprises, for example, one or more elements for weighing. These weighing cells can be weighing cells with strain gauges, for example. However, other elements, such as piezoelectric elements, capacitive sensors or inductive sensors, may also be used.

Weighing plates may be arranged above these weighing cells, respectively, which transmit the weight force of the food to be measured to the measuring cells of the weighing cell.

In order to protect the weighing device from contamination (in particular liquid), according to one variant of the domestic refrigerator according to the invention, the weighing device has a liquid-repellent (in particular liquid-tight) protective film or pad which lies flat on the weighing surface of the weighing cell. The protective mat is in particular designed such that it has a significantly lower rigidity in the region corresponding to the boundary region of two adjacently arranged weighing cells than in the region of the protective mat corresponding to the weighing area of a single weighing cell. The protective mat preferably has a significantly lower rigidity in the boundary region, so that decoupling of the individual weighing areas and thus of the individual weighing cells can be achieved at least to some extent.

The protective film or pad may also enclose each individual weighing surface (or weighing plate) of these individual weighing cells.

The protective pad can be connected to the weighing device (in particular to the carrier of the weighing device) in a force-fitting manner (for example by tensioning), in a form-fitting manner (for example by means of a dovetail groove) or in a material-fitting manner (for example by means of gluing, welding or hot pressing).

The surface of the protective film or pad facing away from the weighing cell forms, in particular, a resting surface for food. The surface can be embodied or structured as a uniform surface (i.e. remain smooth to the same extent).

Preferably, the protective mat can be embodied in one piece and has a smaller material thickness in the region corresponding to the boundary region of two adjacently arranged weighing cells than in the region of the protective mat corresponding to the weighing surface of a single weighing cell. This can be achieved, for example, in this way: the protective film or pad has a weakening structure (or decoupling structure) between the individual weighing cells in order to transfer it only to a small extent or even not at all onto an adjoining weighing cell if there is a disturbance quantity due to the weight loaded onto this adjoining weighing cell.

The integrally formed protective mat can be provided with grooves in a region corresponding to the boundary region of two adjacently arranged weighing cells.

These grooves (or weakening structures) can be arranged in that surface facing away from the weighing cell, i.e. in the surface of the protective mat which constitutes the resting face. A single weighing cell can thus be identified.

These grooves (or weakening structures) may be arranged in that surface of the protective mat which faces the weighing cell. In this case, the surface facing away from the weighing cell (i.e., the resting surface) can be implemented smoothly, for example, it can be cleaned better. In order to identify the individual weighing cells, the placement surface can have, for example, corresponding color lines.

According to a variant of the domestic refrigerator according to the invention, the protective mat can have a rigid plate in each case in the region corresponding to a weighing cell, which rigid plate is connected to the flexible material in the region corresponding to the border region of two weighing cells arranged adjacent to one another. Thereby likewise achieving decoupling of the individual weighing cells.

The carrier can have a frame, which is covered or overlapped by a protective film or pad, or around which the protective film or pad is clasped. This improves the sealing of the weighing device against moisture or liquids.

In order to reliably rest the food on the weighing surface, that surface of the protective mat which faces away from the weighing cell preferably extends higher in the region corresponding to the weighing surface of the individual weighing cell than in the region of the frame. In this way, the shoulder, in particular between the weighing surface and the frame, is compensated for, for example, by adding a step.

The protective mat or film in particular seals the weighing device (and possibly also the door shelf if appropriate).

A plurality of individual weighing cells can be arranged closely and/or tessellately in the weighing region of the weighing device. Within the meaning of the present invention, a checkerboard is also understood to mean a mosaic. It is thereby achieved that the weighing area of the weighing device is occupied as closely and continuously as possible by a single weighing cell.

It can be provided that the weighing region of the weighing device substantially forms the entire resting surface. The weighing region of the weighing device can essentially form the entire resting surface of the storage base and/or of the door shelf.

It can be provided that the weighing surfaces of the individual weighing cells (or the weighing zones of the weighing device) form, partially or largely, the storage surface of the storage base and/or the door shelf.

The refrigerant circuit comprises, for example, a compressor, a liquefier downstream of the compressor, a throttle device downstream of the liquefier, which throttle device is embodied, in particular, as a throttle tube or a capillary tube, and an evaporator, which is arranged between the throttle device and the compressor.

Fig. 2 shows a first embodiment of one of the door shelves 6 in a perspective view, fig. 3 shows a second embodiment of one of the door shelves 6 in a perspective view, and fig. 4 shows a third embodiment of one of the door shelves 6 in a perspective view. The embodiment of the door shelf 6 shown in fig. 2 to 4 is in particular the lowermost door shelf 6. Fig. 5 shows a front view of the door shelf 6 shown in fig. 4 in a cut-away illustration.

The door shelf 6 of fig. 2 to 5 comprises in each case one weighing device 61 which is shown in a sectional illustration in fig. 6 as a side view. The weighing device 61 comprises a plurality of weighing cells 62 arranged directly adjacent to each other.

The bottom of the door shelf 6 comprises weighing devices 61 in such a way that the weighing surfaces 63 of the individual weighing cells 62 jointly form (or open up) a weighing region 66, which weighing region 66 at least partially forms the storage surface 6 a. In the present embodiment, the weighing region 66 constitutes for the most part (or substantially) the entire resting face 6a of the door shelf 6.

In the case of the present embodiment, the first embodiment of the door shelf 6 comprises an upwardly open container 20 (for example made of plastic). The container 20 has in particular a closed bottom 33 and a surrounding wall 21, in which surrounding wall 21 fastening means 22 for fastening the door shelf 6 to the door leaf 5 are formed.

In the first embodiment of the door shelf 6 shown in fig. 2, the weighing device 61 is integrated into the bottom of the container 20.

The weighing device 61 is embodied in particular as an assembly.

In the case of the present embodiment, the second embodiment of the door shelf 6 likewise comprises an upwardly open container 30 (for example made of plastic). The container 30 has a closed bottom 33 and a surrounding wall 31, on which surrounding wall 31 fastening means 32 are formed for fastening the door shelf 6 to the door leaf 5. The weighing device 61 is placed (or inserted) on the bottom 33 of the container 30. The weighing device 61 is in particular fastened to the bottom 33 of the container 30, for example by latching.

In the case of the present embodiment, the third embodiment of the door shelf 6 likewise comprises an upwardly open container 40 (for example made of plastic). The container 40 has an open bottom, or does not contain a bottom. The container 40 comprises a circumferential wall 41, on which circumferential wall 41 fastening means 42 for fastening the door shelf 6 to the door leaf 5 are formed. The weighing device 61, which is designed as an assembly, is fastened to the container 40 in such a way that the container 40 forms the bottom of the door shelf 6 and the downwardly directed surface of the door shelf 6, i.e. closes the container 40 downwardly.

The domestic refrigeration device 1 can have an electronic evaluation device 10 connected to the weighing device 61, which evaluation device 10 evaluates the signals generated by the weighing device 61. The weighing device 61 can be electrically contacted, in particular for supplying said weighing device 61 with electrical energy or for communicating with an analysis processing device 10, which is arranged, for example, in the door leaf 5 or in the heat-insulated housing 2, for example, in that the weighing device 61 has an electrical plug connection which is coupled to a mating electrical plug connection arranged on the door leaf 5.

The weighing device 61 comprises a single (or separate) weighing cell 62.

In the case of the present exemplary embodiment, the individual weighing cells 61 are arranged in an array. For example, it is provided that six weighing cells 62 are arranged next to one another in the longitudinal direction of the door shelf 6 and that two weighing cells 62 are arranged next to one another transversely to the longitudinal direction.

The individual weighing cells 62 are preferably of rectangular design, whereby the boundary region 65 between two adjacent weighing cells 62 is kept as small as possible, so that the weighing plate which forms (or comprises) the weighing surface 63 of an individual weighing cell 62 forms the weighing region 66 as continuously as possible and well covers the entire resting surface 6 a.

In addition to the weighing surface 63, the weighing cell 62 comprises, in particular, a load cell 64 coupled to the weighing surface 63 (or weighing plate), the output signal of which load cell 64 corresponds to the measured mass (or the measured weight) and is determined for evaluating the processing device 10.

The weighing device 61 comprises in particular a trough-shaped carrier 71 shown in fig. 7, which carrier 71 has a receptacle 72 for fastening the individual weighing cells 62.

The carrier 71 comprises in particular a frame 73, by means of which frame 73 the weighing device 61 is fastened, for example, to the receptacle 40 of the third embodiment of the door shelf 6 so as to constitute the bottom of the door shelf 6.

In the case of the present exemplary embodiment, the weighing device 61 comprises a liquid-repellent (in particular liquid-tight) protective mat 81 shown in fig. 8, which protective mat 81 lies flat on the weighing surface 63 of the weighing cell 61. The protective mat 81 is in particular integrally formed and designed in such a way that the protective mat 81 has a significantly lower rigidity in a region 82 corresponding to the boundary region 65 of two adjacently arranged weighing cells 62 than in a region 83 of the protective mat 81 corresponding to the weighing surface 63 of a single weighing cell 62. Thereby, decoupling of the individual weighing surfaces 63 and thus of the individual weighing cells 62 is achieved at least to some extent. This can be achieved, for example, by: the protective pads 81 have a weakening structure (or decoupling structure) between the individual weighing cells 62.

The regions 82 of the protective mat 81 which correspond to the boundary regions 65 of two adjacently arranged weighing cells 62 can be embodied, for example, as grooves.

The weakening structure of the region 82 of the protective mat 81 corresponding to the border region 65 of two adjacently arranged weighing cells 62 can be arranged in the surface of the protective mat 81 facing away from the weighing cells 62 as shown in fig. 6 and 8.

Fig. 9 and 10 show an alternative embodiment of a protective mat 81, according to which the weakening structure of a region 82 of the protective mat 81 corresponding to the border region 65 of two adjacently arranged weighing cells 62 is arranged in that surface of the protective mat 81 which faces the weighing cells 62. In this case, the resting surface 6a can be embodied smoothly, so that it can be cleaned better, for example. For the purpose of identifying the individual weighing cells 62, the placement surface 6a can have, for example, a corresponding color line.

The protective pad 81 can be connected to the weighing device 61 (in particular to the carrier 71 of the weighing device 61) in a force-fitting manner (for example by tensioning), in a form-fitting manner (for example by means of a dovetail joint), or in a material-fitting manner (for example by means of gluing, welding or hot pressing). In particular, the protective pad 81 overlaps or clasps the frame 73 of the carrier 71.

In the case of the present embodiment, that surface of the protective mat 81 which faces away from the weighing cell 62 preferably extends higher in the region 83 corresponding to the weighing face 63 of the individual weighing cell 62 than in the region 84 of the frame 73.

The protective pads 81 can also be embodied in such a way that the regions 83 corresponding to the weighing cells 62 each comprise a rigid plate, which is connected to a flexible material in the region 82 corresponding to the boundary region 65 of two weighing cells 62 arranged adjacently.

It is also possible for the compartment bottom 7 to have a weighing device 61 associated with its resting surface.

It is also possible for the drawer 8 to have a weighing device 61 associated with its resting surface.

Fig. 11 shows one of the door shelves according to fig. 2 to 4 in a perspective view, wherein the resting surface 6a is partially provided with a weighing device 61. In the present exemplary embodiment, the shelf surface 6a of the door shelf 6 is formed in part by the weighing region 66 of the weighing device 61 and in part by the base 33. The weighing area 66 constitutes approximately half of the resting surface 6 a. In the weighing region 66 of the weighing device 61, a plurality of individual weighing cells 62 are included, which individual weighing cells 62 each have a weighing surface 63 and are arranged directly adjacent to one another. The door shelf 6 is designed as a container 20, the container 20 having a surrounding wall 21, in which surrounding wall 21 fastening means for fastening the door shelf 6 are formed. Furthermore, the detailed aspects, arrangement and connection of the weighing device 61 can be implemented according to the specific embodiment according to fig. 2 to 10.

Fig. 12 shows an embodiment of one of the storage bases 7 of the domestic refrigerator 1 according to the invention in a perspective representation. In this embodiment, the weighing region 66 of the weighing device 61 constitutes substantially the entire resting surface 6a of the storage base 7. The storage surface 6a of the storage base can be surrounded by a surrounding, injection-molded frame, on which fastening means for fastening the storage base 7 to the inner container 3 of the domestic refrigeration appliance 1 are molded. In this embodiment, the weighing device 61 can be embodied as an assembly which is fastened to the placement surface 6a of the storage base 7, or the weighing device 61 can be integrated into the placement surface 6a of the storage base 7. The storage base 7 may also have a continuous base on which the weighing device 61 is placed. Furthermore, the detailed aspects, arrangement and connection of the weighing device 61 can be implemented according to the specific embodiment according to fig. 2 to 10. The storage base 7 in this embodiment can also be essentially the bottom of the drawer 8.

Fig. 13 shows a perspective view of a further embodiment of the domestic refrigerator 1 according to the invention in the storage base 7. In the present embodiment, the weighing region 66 of the weighing device 61 partially forms the placement surface 6a of the storage base 6. The rest of the resting surface 6a is constituted by a fixed bottom 33. The bottom 33 may be made of glass. The weighing area 66 constitutes approximately half of the resting surface 6 a. Naturally, the weighing area 66 of the weighing device 61 can also constitute more or less than half of the resting surface 6 a. In the weighing region 66 of the weighing device 61, a plurality of individual weighing cells 62 are arranged, which individual weighing cells 62 each have a weighing area 63 and are arranged directly adjacent to one another. The weighing surfaces 63 of the individual weighing cells 62 jointly open the weighing region 66 and in this embodiment partially form the placement surface 6a of the storage base 7. The storage base 7 can have a surrounding frame on which fastening means are provided for fastening the storage base 7 to the inner container 3 of the domestic refrigeration appliance 1 according to the invention.

Furthermore, the detailed aspects, arrangement and connection of the weighing device 61 can be implemented according to the specific embodiment according to fig. 2 to 10. The storage base 7 in this embodiment can also be essentially the bottom of the drawer 8.
