[0003] Household refrigeration unit with specific three-position storage of a food storage container on a wall

[0004] One aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a storage compartment for food. This storage compartment can, for example, be a refrigerator compartment or a freezer compartment. The storage compartment is bounded by the walls of the household refrigeration appliance. The household refrigeration appliance also has a food storage container. The household refrigeration appliance has a retaining device with which the food storage container can be detachably attached to one of the walls. The retaining device has a retaining groove into which a coupling tab of the retaining device detachably engages. The retaining device has a contact surface adjacent to the retaining groove, against which a contact element of the retaining device rests.

[0005] It is known that separate food storage containers can be reversibly and detachably attached to walls in household refrigeration appliances, thus defining a storage space. Such walls can, for example, be part of an inner container of the household refrigeration appliance. In particular, they can be, for example, vertical side walls. Another wall that defines a storage space can be, for example, the inside of a door of the household refrigeration appliance. The door also defines this storage space when closed. For example, such a food storage container can be a so-called door divider.

[0006] These reversible fastenings for such food storage containers are diverse. For example, US Patent 9784494 B2 discloses a mounting concept in which engagement elements on the food storage container fit into specific recesses in a wall, thus securing the food storage container to the wall. The back of the food storage container, facing the wall, rests fully against the wall. Furthermore, several engagement elements are provided, each engaging in individually shaped recesses in the wall. The upper, vertically oriented design of the engagement system is particularly complex. Not only that, but also...

[0007] 2 / 49

[0008] Installation is therefore very complex and can lead to jamming and spreading; furthermore, the individual geometry of the respective mounting systems results in a wide variety of force paths. This leads to a relatively undefined support of the food storage container against the wall in the current state of the art. Depending on individual dimensions and manufacturing tolerances, and thus due to resulting positional tolerances, different loads and force applications occur. This can also lead to undesirable deformations and damage, especially to the food storage container. The aforementioned disadvantages are further exacerbated by the essentially precise fit of the mounting elements into the recesses in the wall.

[0009] The upper engagement system in particular is very difficult to manufacture due to the highly individual complexity of the shape of the engagement element on the one hand and the complementary contour of the recess on the other, and is a major cause of the disadvantages mentioned above.

[0010] The object of the present invention is to create a household refrigeration appliance in which the detachable attachment of a food storage container to a wall is improved.

[0011] This problem is solved by a household refrigeration appliance which has the features according to claim 1.

[0012] One aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a storage compartment for food. This storage compartment can, for example, be a refrigerator compartment or a freezer compartment. The storage compartment is bounded by the walls of the household refrigeration appliance. The household refrigeration appliance also has a food storage container. The household refrigeration appliance has a retaining device with which the food storage container can be detachably attached to one of the walls. The retaining device has a retaining groove into which a coupling tab of the retaining device detachably engages. The retaining device has a contact surface adjacent to the retaining groove, against which a contact element of the retaining device rests.

[0013] 3 / 49

[0014] The holding device is designed as a bearing arrangement with at least three points. This is shown in a longitudinal section. The longitudinal section is characterized in particular by a vertical section plane, specifically by a section plane oriented perpendicular to a longitudinal extension of the holding groove. The longitudinal section is therefore, in particular, a plane. The longitudinal section can also be stepped, meaning that sections are located at different points along an axis oriented perpendicular to the longitudinal section. The three-point bearing arrangement is configured such that, when the food storage container is mounted on the wall, three discrete, local, and spaced-apart bearing points are formed as, in particular, direct mechanical contacts between the food storage container and the wall.The wall-mounted state can also be described as the attached, secured final state of the food storage container on the wall. In this state, the food storage container is self-supportingly attached to the wall by means of the mounting device and ready to receive chilled goods. The wall can also be referred to as the mounting wall or attachment wall. Such multi-point mounting with at least three such discrete mounting points (and especially only three such mounting points) improves the reversible mounting of the food storage container on the wall. This makes the mounting concept, and thus the attachment of the food storage container to the wall, very simple and targeted. However, this specification of the mounting device is particularly advantageous in that it allows for the creation of very individual and precisely directed force paths.This prevents the occurrence of force peaks in undesirable areas. In particular, it significantly reduces unwanted deformation of the food storage container, especially when loaded. Force peaks can be avoided at transitions in the container's shape, such as corners and / or junctions between a tub-shaped base and a connecting flap. This helps prevent cracks and other damage in these areas.

[0015] These bearing sites, which are only locally formed and, in particular in this longitudinal section, locally limited and defined and separated from each other, enable in the202303517

[0016] 4 / 49

[0017] This also includes a bearing system, which is particularly advantageous for its ability to work together to dissipate forces. Due to the defined boundaries, the bearings themselves are clearly identifiable and thus precisely defined in terms of geometry and position. A particular advantage is that force paths are formed only through these local bearings, enabling a highly defined and directional force application into the wall.

[0018] The bearing points are formed, at least in the longitudinal section, of the food storage container when subjected to a weight force, particularly when loaded with stored goods. However, the bearing points may also be formed in the non-weight-bearing state, i.e., in a state where no additional weight acts besides the weight of the food storage container. The bearing points are formed, in particular, in the final state of the food storage container.

[0019] In one embodiment, the bearing points are separated from each other and do not merge into one another, so that different components of the food storage container are directly attached to different wall areas. In this respect, the wall areas are separated from each other. This also means that two bearing points are not formed on the same flat area of ​​the wall.

[0020] In one embodiment, the food storage container, particularly when viewed in longitudinal section, is in mechanical contact with the wall only at the bearing points, and in particular in direct mechanical contact. In particular, the food storage container is otherwise arranged without contact with the wall when viewed in longitudinal section. This is a very advantageous embodiment, as it minimizes and precisely controls the direct mechanical contact between the food storage container and the wall. Direct contact is only established at these locally defined and limited bearing points, thus achieving direct contact between the two components. This results in a particularly noteworthy configuration of a force path system with these bearing points, defined in longitudinal section by at least three, and in particular only three, points.Furthermore, the contactless arrangement of the food storage container in the remaining storage areas (202303517)

[0021] 5 / 49

[0022] This design is also advantageous with regard to preventing unwanted rubbing of the food storage container against the wall. Scratches or scuff marks, especially when the food storage container is moved along the longitudinal direction of the retaining groove while in its final position (i.e., in the suspended position), can thus be better avoided. Even when the food storage container is in various states of contents, such as completely empty, partially filled, or fully filled, the number of these locally defined and limited contact points remains unchanged. In particular, even in these different states of contents, no further contact occurs between the food storage container and the wall in one embodiment.This also prevents, for example, the creation of additional contact points between the food storage container and the wall due to certain deformations caused by individual loading with stored goods. These additional contact points could create undesirable connections and potentially alter the mechanical force paths at the defined at least three bearing points, particularly weakening them or changing the direction of the force path. Thus, for example, a slight bulging of the food storage container when loaded with stored goods does not contribute to the creation of undesirable additional contact points between the food storage container and the wall.

[0023] In one embodiment, the holding device is configured such that, particularly when viewed in this longitudinal section, a first force path is formed at a first bearing point, oriented essentially perpendicular to the wall, and in particular perpendicular to a principal extension plane of the wall. At a second bearing point, in one embodiment, a second force path is formed, oriented essentially parallel to the wall, and in particular parallel to a principal extension plane of the wall. At a preferably present third bearing point, a third force path is formed, oriented essentially perpendicular to the wall, and in particular perpendicular to a principal extension plane of the wall. This third force path is oriented in the opposite direction to the first force path. This ensures that essentially only force paths that are perpendicular to each other are formed.In this context, "essentially" means that there are maximum deviations of ± 5° to 202303517.

[0024] 6 / 49

[0025] Horizontal or vertical deviations may occur, or no deviations may occur. In particular, maximum deviations of ± 3°. In particular, deviations of a maximum of ± 1° may occur. Such a defined force path system particularly supports the aforementioned advantages.

[0026] Within the scope of this invention, the vertical direction corresponds to a direction oriented vertically upwards in a properly installed domestic refrigeration appliance. The horizontal direction of the wall corresponds to a perpendicular viewing direction towards the wall by an observer standing in front of the wall. The horizontal direction of the wall corresponds to a direction oriented perpendicular to both the vertical and horizontal directions. The principal plane of extension of the wall defines the plane that encompasses the two largest dimensions of the wall. In a properly installed domestic refrigeration appliance, the principal plane of extension lies in a plane spanned by the vertical and horizontal directions.

[0027] In one embodiment, the second bearing point, viewed in the vertical direction of the household refrigerator, is located between the first and third bearing points. In another embodiment, the second force path, viewed in the vertical direction of the household refrigerator, is oriented downwards, meaning that a force is directed downwards from the food storage container into the wall. In yet another embodiment, the second force path, viewed in the plane of the longitudinal section, is perpendicular to, or substantially oriented towards, the other two force paths. This orientation, as well as the positional arrangement of the force paths relative to each other, is a further concept specifically designed to support the aforementioned advantages.

[0028] In one embodiment, a bearing point, in particular a third bearing point, is formed outside the retaining groove. Viewed in longitudinal section, the food storage container is in direct contact with the wall outside the retaining groove, specifically only through this local contact with this single bearing point. Viewed in the plane of the longitudinal section, this bearing point has a smaller height than the height of a side wall of the food storage container facing the wall. Thus, the locally confined and relatively small bearing point, compared to the height of the side wall, is both positionally and in terms of its 202303517

[0029] 7 / 49

[0030] The direct contact surface with the wall is very defined and precisely specified. This allows for the creation of a highly precise force path at a very local point, both in terms of its direction and its point of application.

[0031] In one embodiment, this bearing point is formed by a horizontally and, in particular, only locally projecting bearing projection, especially a bearing web, and this contact surface. The bearing projection can project locally, especially in the depth direction of the wall. In this context, the bearing projection, especially the bearing web, is an example of the contact element. The bearing projection, especially the bearing web, can be continuous and thus continuous. However, it can also be segmented and formed by two or more separate web segments, which together constitute the overall geometry of the bearing projection, especially the bearing web. Such a bearing web is, on the one hand, mechanically very stable and correspondingly load-bearing. It is therefore inherently very rigid and dimensionally stable. This makes it particularly suitable for establishing a locally very precise force path to the wall.Undesirable tolerances can thus be improved and avoided. For example, such a web can form a contact surface that is essentially point-like. Preferably, a contact surface that is essentially linear is formed if the web is elongated. If several separate web segments are present, several spatially separated contact surfaces are formed, each of which is, for example, elongated and thus forms linear contact surfaces. In particular, the bearing web is horizontally oriented in this respect, so that a horizontal contact surface or a horizontal contact strip is formed with the wall's bearing surface.

[0032] Preferably, the height of the bearing projection, in particular the bearing rib, is a maximum of one fifth, in particular a maximum of one tenth, of the height of the side wall of the food storage container on which the bearing projection is formed, or of the total height of the food storage container (measured in the vertical direction in each case).

[0033] This local limitation and the particularly advantageous value of the size ratios mentioned here also support the advantages mentioned above. 202303517

[0034] 8 / 49

[0035] In one embodiment, the bearing projection, in particular the bearing rib, is integrally formed on a side wall of the food storage container facing the wall. The side wall is, in particular, a rear wall of the food storage container and / or is oriented (completely or at least substantially) parallel to a main extension plane of the wall. The bearing projection, in particular the bearing rib, extends beyond a remaining area of ​​this side wall in the direction of the wall-side contact surface.Such a cantilevered and exposed design of the bearing platform, specifically directed towards the mounting surface, supports on the one hand a highly precise and locally exactly limited contact point, and on the other hand it is also advantageously supported by the fact that in the area surrounding the bearing platform this side wall is at least partially spaced away and thus arranged without contact to the wall to which the food storage container is detachably attached.

[0036] In particular, this side wall of the food storage container is only in contact with the bearing projection, especially the bearing rib, and is otherwise spaced outside the holding groove from this wall.

[0037] In one embodiment, the bearing projection, in particular the bearing web, is formed in a lower third of the side wall when viewed in the vertical direction. Specifically, it is formed at a lower end of the side wall, e.g., at an edge. This downward positioning of the bearing web allows for a particularly advantageous installation concept. In particular, in an advantageous embodiment, a maximum distance is thus formed between this bearing point external to the retaining groove and the retaining groove, especially in the vertical direction.

[0038] This allows the corresponding leverage forces to be optimally represented and derived in this cantilevered storage of the food storage container on this particularly vertical or essentially vertical wall.

[0039] In particular, in one embodiment, especially in longitudinal section, only one such external bearing point is formed. 202303517

[0040] 9 / 49

[0041] In one embodiment, the coupling tab, particularly when viewed in this longitudinal section, is odd-shaped. Specifically, it is L-shaped. This specific geometry facilitates a simple coupling concept for inserting the coupling tab into the retaining groove. Furthermore, it enables a very simple geometry, which in turn promotes very precise local contact of the coupling tab with a boundary wall of the retaining groove. In particular, the L-shape is strictly L-shaped. This means that the L-shape has only two legs. These two legs are oriented at an angle between 88° and 92°, particularly between 89° and 91°, and especially at 90° to each other. In one embodiment, the coupling tab has a horizontal leg. The coupling tab also has a vertical leg. At least the vertical leg, and in particular both the vertical and horizontal legs, engage in the retaining groove.

[0042] In one embodiment, the vertical leg engages in an undercut pocket of the retaining groove oriented in the vertical direction of the household refrigeration appliance. The vertical leg rests with its front face, which is oriented towards the receiving space, against a front boundary wall of the retaining wall. This front boundary wall delimits the undercut pocket, particularly towards the receiving space. Specifically, this vertical leg rests directly (completely or at least partially) with its front face against this front boundary wall. This forms a bearing point. In particular, this forms the first bearing point. In one embodiment, at least the portion of the vertical leg whose front face rests against the front boundary wall is oriented exclusively vertically. Specifically, the area of ​​the boundary wall against which the vertical leg rests directly is oriented exclusively vertically.This creates a contact area between this vertical leg and the front boundary wall, forming a plane oriented exclusively in the vertical direction. This concept particularly favorably supports the highly precise generation of a force path that acts in the horizontal direction and is directed from this vertical leg into this front boundary wall.

[0043] In one embodiment, the horizontal leg of the coupling tab engages in an entry area of ​​the retaining groove oriented in the horizontal direction of the household refrigeration appliance. This is also shown in particular in longitudinal section. The horizontal leg lies 202303517

[0044] 10 / 49

[0045] With its underside facing upwards, viewed from above, the retaining groove rests against a lower, particularly horizontal, boundary wall. This lower boundary wall limits the entry area of ​​the retaining groove downwards. Specifically, this horizontal leg rests (completely or at least partially) directly and flat against the lower boundary wall. This configuration forms a bearing point. In particular, it forms the second bearing point. This configuration advantageously defines a force path oriented vertically. Thus, a force path is directed from this horizontal leg into this lower boundary wall.

[0046] In one embodiment, the coupling tab is arranged at the upper end of the food storage container in the vertical direction of the household refrigerator. In particular, this coupling tab is designed to be cantilevered. Specifically, a portion of it projects vertically upwards. The coupling tab, particularly in connection with at least one portion of it, is the highest element of the food storage container.

[0047] In particular, this coupling tab, viewed vertically, is cantilevered upwards from a trough-like base element or base body of the food storage container, or extends upwards. This trough-like base element can be a receiving tray. Specifically, this trough-like base element has an upper rim. The coupling tab is formed at this upper rim. Specifically, this coupling tab is formed at the upper rim of this trough-like base element that faces the wall or is closest to it.

[0048] In one embodiment, the retaining groove and the coupling tab form a hanging device, as an example of a holding device. In particular, the food storage container is self-supportingly attached to the wall by means of this hanging device. In this context, the coupling tab forms a hanging tab that engages in this retaining groove.

[0049] The food storage container can only be reversibly removed from the wall using this hanging device. (Horizontal position) 202303517

[0050] 11 / 49

[0051] It is cantilevered. This means that its base is not supported by any other element. Furthermore, there is no additional support element on the side of the tub-like base facing away from the wall, which would hold the food storage container in its assembled final position in addition to the support provided by other walls.

[0052] In one embodiment, the food storage container is a door divider. In particular, the wall is then an inner side facing the receiving space or an inner wall of a door of the household refrigerator.

[0053] In general, it can be said that this defined three-point mounting system allows the entire weight of the food storage container to be absorbed and distributed in a defined manner in its mounted final position. In particular, this ensures a stable and secure positioning of the food storage container against the wall, especially when loaded. This prevents the food storage container from potentially sliding away from the wall or from the mounting device becoming unintentionally loose or even partially loose.

[0054] In particular, only one coupling tab is provided, which engages in a single retaining groove. This means that the coupling tab itself can be a continuous tab element. However, it is also possible for the coupling tab to be segmented and, for example, have at least two separate tab parts. These are arranged in a row along the longitudinal direction of the coupling tab (and thus also along the longitudinal direction of the retaining groove), so that, in this respect, there is again essentially a single coupling tab with these multiple sub-elements. The same can be said for the retaining groove. This, too, can be a continuous structure or be formed from several groove sections that are separate from one another but, for example, are located at the same height on the wall and are coaxial in the direction of their longitudinal axes.

[0055] It is possible that a retaining groove has a length in its longitudinal direction that is essentially the length of the coupling tab (or the length in the longitudinal direction of the retaining groove202303517

[0056] 12 / 49

[0057] The length of the food storage container corresponds to the length of the retaining groove. This means that the food storage container can essentially only be positioned in one location on the retaining groove. However, it is also possible for the retaining groove to be, for example, at least 10%, in particular at least 20%, in particular at least 30%, in particular at least 100% and / or a maximum of 200% larger or longer than a coupling tab (or, if two, three or more separate coupling tabs are provided, larger or longer than the maximum distance between two end faces of the outermost coupling tabs measured along the longitudinal axis of the retaining groove). This allows a food storage container to be positioned at different locations on this retaining groove or, when suspended, to be moved along the longitudinal axis of the retaining groove.

[0058] Preferably, the external bearing point is also a defined force transmission structure or a support structure. This structure projects upwards in relation to the rest of the surface of the side wall of the food storage container on which this bearing ledge is arranged.

[0059] The retaining groove can be formed on the wall. In this case, the coupling tab is formed on the food storage container. Alternatively, in another embodiment, the retaining groove is formed on the food storage container and the coupling tab is formed on the wall.

[0060] Another independent aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a storage compartment for food. This compartment can, for example, be a refrigerator compartment or a freezer compartment. The storage compartment is bounded by the walls of the household refrigeration appliance. The household refrigeration appliance also has a food storage container. The household refrigeration appliance has a retaining device with which the food storage container can be detachably attached to one of the walls. The retaining device has a retaining groove into which a coupling tab of the retaining device detachably engages.

[0061] The retaining groove, particularly when viewed in a longitudinal section of the household refrigeration appliance, has a substantially horizontally oriented bottom wall as a boundary wall.202303517

[0062] 13 / 49

[0063] a hollow area of ​​the retaining groove. The longitudinal section is defined, in particular, by a vertical plane. Viewed in the vertical direction of the domestic refrigeration appliance, the retaining groove above the bottom wall has a substantially vertically oriented first side wall as the boundary wall of the hollow area of ​​the retaining groove. The bottom wall and the first side wall are designed as contact surfaces for the coupling lug. "Substantially" here means that a deviation of a maximum of + / - 5°, in particular a maximum of + / - 3°, and in particular a maximum of + / - 1° from the horizontal or vertical occurs. In particular, manufacturing and assembly tolerances that may occur should also be taken into account here.

[0064] This results in two very well-defined boundary walls of the retaining groove, which are specifically oriented relative to each other according to the invention, each forming an individual contact surface of the retaining groove itself for the coupling tab. This provides two separate and spaced-apart contact surfaces on the retaining groove side for the coupling tab. A very directed and precisely defined coupling point or bearing point of the coupling tab on the boundary walls of the retaining groove is thus provided. A particularly advantageous force path system for defining specific force paths, by which forces are introduced from the coupling tab into the wall, is thereby provided.

[0065] In one embodiment, the bottom wall extends horizontally, particularly in a cross-sectional plane oriented perpendicular to the longitudinal extent of the retaining groove, beyond the horizontal position of the vertically oriented first side wall and further towards the receiving space. Thus, the bottom wall extends further towards the receiving space than the horizontal position of the vertical first side wall, which acts as a boundary wall. This advantageously creates an entry area for the retaining groove, upon which the coupling tab can be precisely positioned and supported during the mounting or attachment of the food storage container to the wall, before engaging in the further retaining groove. This engagement, in particular, allows the food storage container to reach its final position through a corresponding pivoting movement.Furthermore, this makes it possible for the two mounting surfaces for the coupling tab to be aligned in this horizontal direction in relation to the position in the recording space202303517.

[0066] 14 / 49

[0067] The contact surface, or contact point, between the horizontal base wall and the coupling lug is positioned, at least in some areas, further towards the receiving space than the contact area between the vertical first side wall and the coupling lug. This horizontal offset between the two coupling points or bearing points formed in the retaining groove significantly supports the aforementioned concept with very defined and, in particular, precisely aligned force paths relative to each other. Specifically, these two force paths are perpendicular or substantially perpendicular to each other when viewed in the longitudinal section.

[0068] In one embodiment, particularly in the longitudinal section, the horizontally dimensioned overhang between an end of the bottom wall facing the receiving space and the first side wall is between 3 mm and 9 mm, particularly between 4.5 mm and 7 mm, and particularly 6 mm. This overhang dimension enables, on the one hand, a compact installation space concept, and on the other hand, it significantly supports the aforementioned advantages with regard to the differently oriented bearing points on the retaining groove side. In particular, the force paths can be designed and oriented in a particularly defined manner.

[0069] In one embodiment, the retaining groove is L-shaped, particularly when viewed in longitudinal section. This cross-sectional shape is, on the one hand, a very simple geometry. This allows for quick and easy insertion of the coupling tab. It also facilitates disassembly and thus removal of the coupling tab from the retaining groove. On the other hand, this cross-sectional shape also ensures particularly stable positioning and supports the aforementioned advantageous bearing points on the retaining groove side and the force paths thus achievable.

[0070] In one embodiment, the retaining groove, which is L-shaped particularly in longitudinal section, has a vertically oriented retaining groove area. This is specifically formed as an undercut pocket. Thus, a pocket area of ​​the retaining groove is formed in the vertical direction, which is closed in the horizontal direction and therefore towards the receiving space, or is limited by the vertical first side wall. Furthermore, this vertically oriented retaining groove area

[0071] 15 / 49

[0072] The rear side wall is bounded by a second, predominantly vertically oriented, rear side wall. This rear side wall and the front side wall (in relation to the recording space in this longitudinal section) are arranged parallel to each other, at least in certain areas, and particularly along their entire height. This further supports the advantages mentioned above.

[0073] In one embodiment, the horizontal width of the vertically oriented retaining groove area, measured particularly in longitudinal section, is between 4 mm and 10 mm, more specifically between 5.5 mm and 8.5 mm, and more specifically 7 mm. This dimension is particularly advantageous because it creates an upwardly oriented pocket area that allows for easy insertion and threading of the coupling tab with a corresponding section. In particular, this relatively large width also provides sufficient clearance to enable this threading process, and especially the pivoting in and out of the coupling tab with the corresponding section, without jamming.Furthermore, this dimensioning also enables the precise positioning of the coupling tab, with its front facing the receiving space, against this front boundary wall or this first front vertical side wall that defines this vertically oriented retaining groove area. This achieves particularly precise alignment and the largest possible contact area between the portion of the coupling tab that engages in this vertically oriented retaining groove area and the first vertical side wall. Nevertheless, in an advantageous embodiment, when viewed horizontally in the assembled final position of the food storage container against the wall, a gap or clearance exists between this portion of the coupling tab and the rear second side wall.In particular, this horizontally measured clearance, or the clear width, is then larger, in particular by up to three times, in particular by twice, the thickness of the coupling tab element in this upwardly oriented retaining groove area in this horizontal direction. In particular, the clearance is at least half as large as the thickness.

[0074] In one embodiment, the vertical height of this vertically oriented retaining groove area, measured particularly in longitudinal section, is between 3 mm and 9 mm. In particular, this vertical height is between 4.5 mm and 7.5 mm, especially 6202303517.

[0075] 16 / 49

[0076] mm. This height dimension allows, on the one hand, for a compact retaining groove, so that the wall—that is, the retaining or mounting wall to which the food storage container is to be detachably attached—does not have to be formed with undesirably large structures protruding from the plane. On the other hand, a sufficient height dimension is provided to enable a stable mechanical connection between the coupling tab and the first vertical side wall, which forms the boundary of this hollow area.

[0077] In one embodiment, the L-shape has a horizontally oriented retaining groove area. This horizontally oriented retaining groove area is bounded by the bottom wall and, in particular, a substantially horizontally oriented ceiling wall. Specifically, this horizontally oriented retaining groove area also includes the entry area of ​​the retaining groove. This is the opening of the retaining groove formed towards the receiving space.

[0078] In one embodiment, the vertical height of the horizontally oriented retaining groove area, particularly as measured in this longitudinal section, is between 8 mm and 16 mm, in particular between 10 mm and 14 mm, in particular 12 mm. This height dimension allows for easy insertion of the coupling tab, especially in a tilted position, so that pivoting of the coupling tab is also possible during the further installation process and sufficient installation space is provided in the retaining groove for this purpose.

[0079] In one embodiment, the retaining groove, viewed in the vertical direction of the household refrigeration appliance, particularly in the longitudinal section, has a further vertical side wall on the side facing away from the receiving space, which delimits the retaining groove and, in particular, the hollow area of ​​the retaining groove. This further side wall is, in particular, essentially vertical. Specifically, it is vertical over its entire length or height. This also enables the aforementioned simple insertion of the coupling tab without requiring complex maneuvering movements past uneven boundary structures in this rear area of ​​the retaining groove. Particularly smooth and jam-free insertion of the coupling tab, and especially its targeted upward guidance, is thus possible. This is particularly true when an upper edge of the coupling tab then...202303517

[0080] 17 / 49

[0081] The rear side wall of the retaining groove is directly contacted and can be guided upwards by a pivoting movement.

[0082] In one embodiment, the radius formed between an upper end of the further vertical side wall and a roof wall of the retaining groove is between 1.5 mm and 4.5 mm, in particular between 2 mm and 4 mm, in particular 3 mm.

[0083] In one embodiment, the radius between the lower boundary wall and a lower end of the further vertical side wall is smaller than the radius between the upper end of the further vertical side wall and the roof wall.

[0084] In particular, the retaining groove, viewed in a horizontal section, has a lateral boundary wall. The horizontal section is formed in a plane perpendicular to the longitudinal section. This lateral boundary wall of the retaining groove is inclined at least in one section at an angle greater than 0° to a plane, the plane being oriented perpendicular to the longitudinal axis of the retaining groove. Thus, in the horizontal section, this lateral boundary wall is inclined to a horizontal line. Specifically, it may be provided that the retaining groove, viewed in this horizontal section, tapers from an entrance opening facing the receiving space to a rear boundary wall or a rear side wall facing away from the receiving space, or that the clear width (in the longitudinal direction of the retaining groove) decreases accordingly. In particular, this lateral boundary wall is inclined along its entire length.This design of the lateral boundary wall, viewed in the horizontal section, and in particular the two opposing lateral boundary walls, which are each inclined accordingly, creates a funnel-shaped or trapezoidal contour area in this horizontal section. This automatically ensures a certain orientation of the food storage container in this direction along the longitudinal axis of the retaining groove when the coupling tab is inserted. With an inclined side wall of the retaining groove according to this embodiment, the end sections of the coupling tab can also have inclined end surfaces in the horizontal section. Preferably, these end surfaces are parallel or at least substantially parallel to the inclined side walls of the retaining groove. In this way, the entrance area of ​​the retaining groove can be...

[0085] 18 / 49

[0086] The retaining groove (at both ends) extends far towards an end section of the wall, while the hollow area of ​​the retaining groove is constricted or reduced in the longitudinal direction of the retaining groove in the area of ​​the wall end sections. This simplifies the manufacturing of the wall; for example, if the wall is the inside of a door, the formation of a sealing groove running along the wall end sections to accommodate a door seal can be simplified, as an interfering contour caused by the hollow area of ​​the retaining groove is avoided. At the same time, by having the end sections of the coupling tab have a corresponding angle, maximum extension of the food storage container can be provided in the longitudinal direction of the retaining groove.

[0087] In one embodiment, the angle is between 10° and 30°, in particular between 15° and 25°, and in particular 20°. In one embodiment, at least the section of this lateral boundary wall is straight. This section extends over at least 75% of the total length of this lateral boundary wall. In particular, it extends over at least 90%, and in particular over 100%, of this length of the boundary wall. This length is measured in the horizontal section.

[0088] In one embodiment, the retaining groove is integrally formed with the wall. The retaining groove is thus formed in one piece with the wall, and is therefore an integral part of the wall. In particular, the retaining groove is formed by deforming a corresponding section of the wall.

[0089] In one embodiment, the retaining groove, and in particular the hollow area of ​​the retaining groove, is designed as a closed pocket. A gap behind the wall, which is filled, for example, with thermal insulation material, is thus limited or sealed by the wall including the retaining groove. When inserting the thermal insulation material into the gap, no further sealing measures are required in the area of ​​the retaining groove, thereby simplifying the manufacture of the household refrigeration appliance. 202303517

[0090] 19 / 49

[0091] In one embodiment, the wall is an inner wall of a door of the household refrigerator, and a wall of an inner container of the housing of the household refrigerator has a further retaining groove. This further retaining groove is functionally, and in particular geometrically, identical to the retaining groove in the inner wall of the door, so that the described features for the retaining groove are also applicable to the further retaining groove. The food storage container can thus be attached either by means of the retaining groove on the door or by means of the further retaining groove in the housing. The retaining groove that is not in use is hardly noticeable to a user, as it is directed entirely towards the space between the components. This is especially true if a vertically oriented section of the retaining groove extends upwards, since this section is typically not visible.

[0092] In one embodiment, the retaining groove extends exclusively in the depth direction of the wall when viewed perpendicularly from the receiving space (provided the wall is an interior wall of the door: with the door in the closed position). The retaining groove thus extends towards a cavity located behind the wall and filled with thermal insulation material. This simplifies cleaning the wall for the user.

[0093] In one embodiment, the coupling tab of the wall-mounted food storage container is completely received in the retaining groove.

[0094] In one embodiment, the coupling tab has an L-shape, particularly in longitudinal section. In this embodiment, the coupling tab is designed with a vertically oriented leg that engages with clearance in a vertically oriented undercut pocket of the retaining groove. Specifically, the horizontal clearance of the coupling tab in this undercut pocket or the vertically oriented retaining groove area, as arranged in the assembled final state, is greater than or equal to 20%, and more specifically between 20% and 300% or between 100% and 250%, of the thickness of the vertically oriented leg as measured in this horizontal direction. This further supports the advantages already mentioned above with regard to a simple assembly and disassembly concept.In particular, this provides a particularly advantageous way to implement a plant concept formed in the holding groove with defined bearing points on the holding groove side between the coupling lug and 202303517.

[0095] 20 / 49

[0096] The retaining groove is supported by its boundary walls. In particular, only locally formed bearing points are defined, extending only over partial surfaces of the boundary walls defining the retaining groove and only over partial surfaces of the coupling lug projecting into the retaining groove. Therefore, full contact of all surfaces of the coupling lug with the boundary walls of the retaining groove is not achieved.

[0097] Another independent aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a storage compartment for food. This storage compartment can, for example, be a refrigerator compartment or a freezer compartment. The storage compartment is bounded by the walls of the household refrigeration appliance. The household refrigeration appliance also has a food storage container. The household refrigeration appliance has a retaining device with which the food storage container can be detachably attached to one of the walls. The retaining device has a retaining groove into which a coupling tab of the retaining device detachably engages. The retaining device has a contact surface adjacent to the retaining groove, against which a contact element of the retaining device rests.

[0098] At least one component of the system only makes local contact with the mounting surface when the food storage container is in its final, mounted position against the wall. This creates a local support structure to brace the food storage container against the wall. This means that the food storage container does not make full contact with the wall outside the mounting groove across its entire outer surface facing the mounting surface. Therefore, it only makes contact with the mounting surface over a relatively small area. This smaller area is formed by the support structure defined above, thus providing only this local contact point for the component. In other respects, the food storage container cantilevers freely against the wall.

[0099] This allows for a specifically defined and locally predefinable force application point outside the holding groove. 202303517

[0100] 21 / 49

[0101] In one embodiment, this bearing point is formed by a horizontally and, in particular, only locally projecting bearing web and this contact surface. The bearing web is, in this context, an example of the contact element.

[0102] In one embodiment, the bearing rib is integrally formed on a side wall of the food storage container facing the wall. It is thus integrated into this side wall and therefore formed integrally with it. This bearing rib projects upwards towards the wall-side contact surface over the remaining area of ​​the side wall. In particular, it projects horizontally towards the wall-side contact surface. This side wall of the food storage container facing the contact surface therefore only rests directly against the contact surface at this defined bearing point outside the retaining groove, and a contact area is only formed there. Otherwise, this side wall of the food storage container, which faces the contact surface and is located outside the retaining groove, is positioned at a distance from this contact surface.

[0103] In particular, the bearing projection, especially the bearing rib, is formed in a lower third of the side wall of the food storage container facing the contact surface, viewed in the vertical direction. Specifically, this bearing projection, especially the bearing rib, is formed directly at a lower end of this side wall.

[0104] In one embodiment, the height of the bearing projection, in particular the bearing web, measured in the vertical direction, is a maximum of one-fifth, and in particular a maximum of one-tenth, of the height of the side wall facing the contact surface, or of the total height of the food storage container. In one embodiment, the contact area with which the bearing web directly abuts the contact surface is a maximum of 30%. In particular, this contact area is a maximum of 20%. In particular, it is a maximum of 10% of an area of ​​the side wall of the food storage container facing this contact surface. In one embodiment, the contact area with which the bearing web directly abuts the contact surface is at least 1%, and in particular at least 3%, of an area of ​​the side wall of the food storage container facing this contact surface.

[0105] 22 / 49

[0106] is facing the wall when the food storage container is in its mounted final position against the wall or the mounting wall.

[0107] In one embodiment, the bearing projection, in particular the bearing rib, extends over at least 1%, in particular at least 5%, in particular at least 20%, in particular at least 30%, in particular at least 40%, in particular at least 50% of a horizontal overlap length between the food storage container and the wall. This means that the bearing projection, in particular the bearing rib, extends only partially along this horizontal extension of the food storage container, in particular along this side wall facing the contact surface, or it extends over the entire length of this side wall. It is possible that the bearing projection, in particular the bearing rib, is designed as a continuous bearing projection or bearing rib. It is also possible that the bearing projection, in particular the bearing rib, is formed from several bearing rib sections that are separated from one another.This creates corresponding bearing support segments. These can be formed at the end regions of the side wall when viewed in this horizontal direction.

[0108] In one embodiment, the support element is formed along a vertical overlap length between the food storage container and the wall, specifically at a lower third of the vertical overlap length, and particularly at the lower end of the vertical overlap length. This results in particularly advantageous support concepts. In particular, it creates a highly defined and precise concept of different force paths, through which forces can be introduced from the food storage container into the wall, i.e., the mounting wall or the supporting wall, in a very defined direction and at very defined points, namely these bearing points.

[0109] In one embodiment, the height of the support element is between 1 mm and 30 mm, particularly between 1 mm and 5 mm. In particular, this height is between 2.5 mm and 3.5 mm. This height is measured vertically, especially when the food storage container is in its final position. 202303517

[0110] 23 / 49

[0111] In an advantageous embodiment, the horizontal depth of the mounting element is between 0.5 mm and 3 mm, particularly between 1 mm and 2 mm. In particular, this depth of the mounting element is between 1.5 mm and 1.7 mm. This depth thus corresponds to the extent of the projection of the mounting element from the remaining side wall on which the mounting element is formed.

[0112] In one embodiment, the attachment element has a strip-shaped, in particular flat, contact surface. This is intended to be in contact with the mounting surface over a flat area.

[0113] In one embodiment, the component, when viewed in a horizontal section, has a rounded end. This means it is designed without a corresponding point or edge at this point. This prevents unwanted contact or an undesirable edge rubbing against the wall.

[0114] In one embodiment, the food storage container is made of plastic. It is particularly well-made in one piece. In particular, it can be an injection-molded component. The food storage container can also be made of metal or comprise a combination of different materials.

[0115] In one embodiment, the food storage container is a two-component injection-molded part. The attachment element can be made of a first material, and the rest of the food storage container can be made of a different second material. The attachment element can, for example, be made of PTFE (polytetrafluoroethylene).

[0116] The food storage container can, for example, be a door divider. Specifically, it can be attached to (i.e., occupy the final position on) a wall that forms part of the door of the household refrigeration appliance. In particular, this can be an inner wall of the door facing the receiving compartment when the door is closed. 202303517

[0117] 24 / 49

[0118] Another independent aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has a storage compartment for food. This storage compartment can be a refrigerator compartment or a freezer compartment. The household refrigeration appliance has walls. The storage compartment is bounded by these walls. Furthermore, the household refrigeration appliance has a retaining device designed to detachably hold a food storage container to one of these walls. The retaining device has a retaining groove on the wall side for the reversible engagement of a coupling tab on the container side (i.e., part of the food storage container) of the retaining device. The wall on which the retaining groove is formed has a support structure that projects, at least partially, from the plane of the wall. This plane of the wall corresponds to the main extension plane of the wall.This support structure is located adjacent to the retaining groove in the wall, and it stiffens the wall, at least in the vicinity of the groove. The support structure is therefore a stiffening support structure. This improves the secure attachment of a food storage container, particularly within the retaining groove. Forces exerted on the wall by the food storage container in the area of ​​the retaining groove, such as weight forces, leverage forces, or similar forces, are better absorbed. Specifically, the wall in and around the retaining groove is thus more dimensionally rigid and stiffer at the joints. This prevents undesirable deformations of both the retaining groove and the wall in the area or surrounding the retaining groove.In particular, this also improves the storage situation by providing preferably defined bearing points or support locations, which allow a food storage container to be mounted locally on the wall. This is because the force transmission structure formed at each point, which enables defined force paths for transferring force from the food storage container to the wall, can then be precisely defined and permanently functional and precisely positioned. By stiffening the area of ​​the retaining groove and its surroundings with at least one support structure, the bearing points can be maintained more precisely, ensuring that the force paths in the wall are always exact and consistent.

[0119] In one embodiment, the support structure is considered in the vertical direction of the household refrigerator and thus also in the vertical direction of the wall, above the retaining groove202303517

[0120] 25 / 49

[0121] and / or below the retaining groove. Thus, depending on the specific space requirements and the available space, the support structure can be individually positioned relative to the retaining groove.

[0122] In one embodiment, the support structure is formed above the retaining groove, at least when viewed in the vertical direction.

[0123] In particular, each retaining groove can be assigned a single support structure. That is, the number of retaining grooves corresponds to the number of support structures. Specifically, support structures and retaining grooves are arranged alternately in the vertical direction. For example, if the support structure is located above the retaining groove, in this embodiment there is a support structure located vertically above each retaining groove, positioned between that retaining groove and a retaining groove located vertically above it.

[0124] In one embodiment, the support structure comprises at least one structural element. In particular, the support structure is formed by this single structural element. A structural element can, for example, be a channel. Thus, a structural element is a geometrically unique element. In particular, it represents an element that is formed either in the plane of the wall or out of the plane. This allows for a particularly stable stiffening with relatively simple manufacturing.

[0125] The supporting structure can be designed as a depression or as a projection, in each case when viewed perpendicularly from the recording space or from the outside of the wall (i.e. viewed in the depth direction of the wall).

[0126] In one embodiment, a structural element of the support structure is designed as a straight indentation or a straight elevation in the wall. This geometry is also easy to manufacture and yet highly efficient with regard to its stiffening function.

[0127] In one embodiment, the support structure is designed with at least one structural element parallel to the retaining groove in the wall. Thus, it is provided that a 202303517

[0128] 26 / 49

[0129] The longitudinal axis of the retaining groove runs parallel to the longitudinal axis of the structural element. In particular, the structural element is designed parallel to the retaining groove along its entire length. It is specifically provided that, in the direction of the longitudinal axis of the retaining groove, the structural element is formed completely within the length of the retaining groove for at least 50%, in particular at least 60%, in particular at least 70%, in particular at least 80%, and in particular at least 90%. This allows for a particularly efficient stiffening principle. In one embodiment, it is provided that a length of the support element, measured in the longitudinal direction of the retaining groove, corresponds substantially or completely to the length of the retaining groove, and that both overlap completely in the longitudinal direction of the retaining groove (i.e., in the width direction of the wall).

[0130] In one embodiment, at least one structural element of the support structure is designed without undercuts when viewed perpendicularly to the plane of the wall. This means the structural element has no hidden pocket or recess. As a result, the structural element has a particularly simple geometric design and is very easy to manufacture. Especially when the wall is made of plastic, this shape of the structural element can then be produced simply yet precisely.

[0131] In particular, a structural element is not a retaining groove. Therefore, the structural element is not designed to receive a coupling tab of a food storage container. Consequently, a structural element is, at least geometrically and functionally, unsuitable for the secure attachment of a food storage container. This is also evident from its size. Specifically, a structural element is neither designed nor constructed in such a way that a coupling tab of a food storage container could engage with it in a retaining manner.

[0132] In one embodiment, at least one structural element of the support structure is elongated. In particular, the structural element is continuous.

[0133] In one embodiment, at least one structural element of the support structure extends over a length of at most 120%, in particular at most 110%, of the length of the retaining groove. In this respect, a structural element is preferably adapted to the length of the retaining groove.

[0134] 27 / 49

[0135] adapted. This allows both the retaining groove itself and the surrounding area to be stiffened in a very targeted and defined manner.

[0136] In one embodiment, the support structure and / or the retaining groove is spaced away from the lateral edges of the wall when viewed perpendicularly (along the depth direction).

[0137] In one embodiment, at least one structural element of the support structure is designed as a recess in the wall, i.e., directed away from the receiving space. The maximum depth of the recess, measured perpendicular to the plane of the wall, is between 0.2 mm and 1.5 mm, in particular between 0.3 mm and 0.8 mm, and more specifically 0.5 mm. Even such a shallow structural element provides significant stiffening in the vicinity of the retaining groove.

[0138] In one embodiment, the contour of the structural element, formed in cross-section perpendicular to a longitudinal axis of the supporting structure, is cornerless. In particular, this contour is a U-shape or a C-shape in this cross-sectional view. Such a cross-sectional shape is simple to manufacture and yet enables particularly high stability and thus a high stiffening effect. Especially since, compared to angular contours, no geometric compressions and thus no peaks are formed, a more uniform and homogeneous stiffening effect is achieved.

[0139] In one embodiment, the distance, measured in the vertical direction of the household refrigeration appliance, between the upper edge of an inlet of the retaining groove and an adjacent structural element, particularly one positioned above the retaining groove, and especially between the vertical center point of the structural element of the support structure, is between 10 mm and 50 mm, particularly between 20 mm and 30 mm, and particularly between 25 mm. Thus, in the vertical direction, a structural element is formed relatively close to the retaining groove. This achieves a particularly efficient and locally precise stiffening effect. Furthermore, this spaced arrangement of the structural element relative to the retaining groove does not impair the actual shape of the retaining groove and therefore does not affect the coupling process between the food storage container and the wall.

[0140] 28 / 49

[0141] In one embodiment, the clear opening (measured vertically) of an opening in a recessed structural element of the support structure is at most one-fifth, and in particular at most one-tenth, of the clear opening of the retaining groove. Due to these significantly different dimensions, the suitability of the structural element for holding the food storage container, which is not intended for this purpose, is also confirmed. In particular, this relatively small clear opening of the structural element means that the structural element itself is not visually dominant, especially compared to the retaining groove. This also results in a more harmonious appearance of the wall in and around the retaining groove.

[0142] In one embodiment, the support structure is designed without contact with the retaining groove in the wall. This effectively prevents any mutual interference between these two elements.

[0143] In one embodiment, the maximum depth (support structure as a recess) or maximum height (support structure as a projection) of a structural element of the support structure, measured perpendicular to the main extension plane of the wall, is at most one tenth, in particular at most one twentieth, of the maximum depth of the retaining groove measured perpendicular to the main extension plane of the wall.

[0144] In one embodiment, the household refrigeration appliance has at least one food storage container that can be reversibly and detachably attached to one of the walls by means of the holding device. Such a detachable attachment is designed in such a way that the connection can be broken and reassembled without damaging any of the components involved.

[0145] Embodiments of one aspect of the invention are to be regarded as advantageous embodiments of the other independent aspects and vice versa.

[0146] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: 202303517

[0162] In the figures, identical and functionally equivalent elements are given the same reference symbols.

[0163] Figure 1 shows a perspective view of an embodiment of a household refrigeration appliance 1. The household refrigeration appliance 1 is designed for storing and preserving food. It can be a refrigerator or a freezer, or a combination refrigerator-freezer. The appliance comprises a housing 2 or body. The housing 2 contains at least one storage compartment 3 for food. This compartment can be a refrigerator or a freezer. The appliance also includes an inner container 4. The inner container 4 defines the storage compartment 3 with walls. These walls can include vertical side walls 5 and 6, a rear wall 7, a top wall 8, and a bottom wall 9.It is also possible that the receiving chamber 3 is not directly bounded by the walls 5 to 9 of the inner container 4, but that there is at least one separate wall located within the receiving chamber 3 that at least partially covers or clads one of these walls 5 to 9 of the inner container 4 on the side facing the receiving chamber 3. Such a separate wall could, for example, be a cladding wall.

[0164] Furthermore, the household refrigeration appliance has a door 10. Door 10 is shown here in the open position. It can be pivoted about a pivot axis oriented in the vertical direction (y-direction) of the household refrigeration appliance 1. Door 10 is in the 202303517

[0165] 31 / 49

[0166] The connection is movably mounted on the housing 2. The door 10 has a wall 11. This wall 11 is an interior wall. When the door 10 is closed, the wall 11 faces the recording chamber 3. Thus, when the door 10 is closed, this door 11 also delimits the recording chamber 3.

[0167] The household refrigeration appliance 1 also has at least one food storage container. Such a food storage container 12 is shown in Fig. 1. It can, for example, be a so-called door divider. However, it is also possible that a food storage container 12 can be detachably attached to a wall 5 to 9, in particular the vertical side walls 5 and 6 of the inner container 4, or in particular, detachably suspended. A food storage container 12 can be formed by a tub-like or bowl-like body. It is also possible that a food storage container 12 additionally has a lid. In that case, a food storage container 12 can also be a closed box.

[0168] In Fig. 1, the number, position, and geometry of the food storage containers 12 are shown only as examples and are by no means exhaustive. Further explanations regarding a food storage container 12 are presented here, particularly in the context of a door shelf. It should be noted again that a food storage container and the following explanations apply not only to a door shelf but also to a food storage container that can be attached to a wall 5 to 9 of the inner container 4. It is also possible that a food storage container 12 can be attached to either wall 11 or one of the walls 5 to 9 using a holding device, which will be explained later.

[0169] A food storage container 12 can be detachably attached to one of the aforementioned walls 5 to 9, 11 by means of a holding device 13.

[0170] The retaining device 13 has a retaining groove 14. The retaining groove 14 is, in particular, a wall-side retaining groove 14. This means that it is located on the wall to which the food storage container 12 is intended to be detachably attached. The retaining groove 14 is thus on the retaining wall or on the 202303517

[0171] 32 / 49

[0172] The mounting wall is integrally formed, to which a food storage container 12 is detachably attached, particularly by way of suspension. In the exemplary embodiment, several retaining grooves 14 are formed in the exemplary wall 11, of which only some are provided with the reference lines for clarity.

[0173] A retaining groove 14 is formed integrally with the wall 11, which is also formed integrally. The wall 11 can be made of plastic. It can be manufactured, for example, by thermoforming or injection molding.

[0174] In the exemplary embodiment, a retaining groove 14 is, in particular, completely, horizontally oriented. Here, it is oriented in the width direction (x-direction) of the household refrigerator 1 when the door 10 is closed. It has a longitudinal axis A.

[0175] In this context, Fig. 2 shows an embodiment of a door 10 according to the invention for a household refrigerator 1. This door 10 corresponds here to the door 10 in Fig. 1, as it is movably mounted on the housing 2.

[0176] Fig. 3 shows the door 10 facing the wall 11 and the food storage containers 12 removed. The multiple retaining grooves 14, which are oriented parallel to each other, are visible.

[0177] Figure 4 shows a longitudinal section, i.e., a vertical section, of a portion of the door 10. A food storage container 12 is shown here in its assembled final state on the wall 11. It is attached to the wall 11 in a reversibly detachable, free-hanging, and cantilevered manner. The holding device 13 has a mounting device 15. Furthermore, in this embodiment, it also has a support structure 16 or a support device. The holding device 13 has a retaining groove 14 on the wall side. It also has a coupling tab 17 on the container side.

[0178] As shown in Fig. 4, the door 10 has a gap 55 behind the wall 11, which is filled with thermal insulation material. The gap 55 is defined by the 202303517

[0179] 33 / 49

[0180] Wall 11 and a separate exterior wall 56 are bounded. Exterior wall 56 forms the exterior wall of door 10.

[0181] Furthermore, in the exemplary embodiment, the holding device 13 has a contact surface 18. This surface is part of the wall 11 outside the retaining groove 14. Viewed vertically, it is located below the retaining groove 14. This contact surface 18 is designed so that a contact element 19, in particular a container-side contact element 19 of the holding device 13, rests directly against it. In the illustrated embodiment, the holding device 13 is designed as a bearing 20 with at least three points. This three-point bearing 20 is configured such that, in the final, mounted, and held state of the food storage container 12 shown in Fig. 4, three discrete, local bearing points 21, 22, and 23, spaced apart from each other, are formed as direct mechanical contacts between the food storage container 12 and the wall 11.

[0182] In this longitudinal section according to Fig. 4, the food storage container 12 is in direct mechanical contact with the wall 11 only at these three discrete bearing points 21, 22, 23. In particular, it is otherwise arranged without contact with the wall 11 in this longitudinal section. The holding device 13 is configured such that, in this longitudinal section, a first force path 24 oriented perpendicular or substantially perpendicular to the wall 11 is formed at the first bearing point 21. At a second bearing point 22, a second force path 25 oriented vertically or substantially vertically is formed in the wall 11. This second force path 25 is oriented parallel or substantially parallel to a principal extension plane of the wall 11, the principal extension plane of the wall 11 lying in an xy-plane (see Fig. 4).

[0183] 7). Furthermore, at the third bearing point 23, a third force path 26 is formed, oriented essentially perpendicularly into the wall 11, i.e., perpendicular to the main extension plane of the wall. This third force path 26, again oriented horizontally, is oriented in the opposite direction to the first force path 24. As can be seen in Fig. 4, a force path system is thus created in which the several, here three, force paths 24, 25 and 26, viewed in the longitudinal section, are oriented in only two mutually perpendicular spatial directions. The second bearing point 22 is, according to the embodiment in Fig. 4, viewed in the vertical direction.

[0184] 34 / 49

[0185] The second force path 25 is formed between the first bearing point 21 and the third bearing point 23. Viewed vertically, the second force path 25 is oriented downwards. The second force path 25 is essentially perpendicular to the other two force paths 24 and 26 in the plane of the longitudinal section shown in Fig. 4.

[0186] As can be seen in Fig. 4, a bearing point, here the third bearing point 23, is located outside and spaced apart from the retaining groove 14. As can also be seen in Fig. 4, the food storage container 12, viewed in this longitudinal section, is in direct contact with the wall 11 only at this local contact point of the bearing point 23, outside the retaining groove 14. The contact element 19 is arranged here to project upwards from a side wall 27 of a trough-shaped base element 28 of the food storage container 12. The side wall 27 forms the rear wall of the food storage container 12. In particular, this contact element 19 projects upwards towards the wall 11 compared to the remaining area of ​​the side wall 27. The contact element 19 is integrally formed at a lower end 29 of this side wall 27.Except for this local contact of the support element 19 with the support surface 18, which forms the third bearing point 23, the remainder of the side wall 27 is arranged without contact with the wall 11, in particular with the support surface 18 in the area outside the retaining groove 14. As can be seen, the support element 19 has a lower height than the height of the side wall 27. In particular, the height of the support element 19 is at most one-fifth, and more specifically, at most one-tenth, of the height of the entire side wall 27. The support element 19 is designed here as a horizontally projecting bearing web.

[0187] As can also be seen in Fig. 4, the coupling tab 17 is integrally formed on an upper edge 30 of the side wall 27. As can also be seen in Fig. 4, the coupling tab 17 is cantilevered upwards in the vertical direction. In this example, the coupling tab 17 is therefore the element of the food storage container 12 that projects furthest upwards in the vertical direction. Viewed in this longitudinal section according to Fig. 4, the coupling tab 17 preferably has an L-shape. In particular, it has a first leg 31 of the L. This first leg 31 of the L is a horizontal leg. It is essentially horizontally oriented or is completely horizontally oriented. Furthermore, the L-shape has a second leg 32 of the L. This is specifically vertically oriented.

[0188] 35 / 49

[0189] Completely vertically oriented or substantially completely vertically oriented. As shown in Fig. 4 in the assembled final state of the food storage container 12 on the wall 11, the coupling tab 17 with both L-shaped legs 31 and 32 engages in the retaining groove 14. The retaining groove 14 is also L-shaped in longitudinal section. It has a vertically oriented retaining groove section 33. This is designed here as a vertically oriented undercut pocket. In addition, the retaining groove 14, viewed in this longitudinal section, has a horizontally oriented retaining groove area 34. This horizontal retaining groove area 34 also has an entry area or an entry opening 35, which is open towards the receiving chamber 3.

[0190] As can be seen in Fig. 4, in this longitudinal section, the retaining groove 14 is bounded downwards by a bottom wall. This bottom wall thus forms a lower boundary wall 36 of the cavity 37 of the retaining groove 14. This horizontal retaining groove area 34 is further bounded by an upper, horizontally oriented boundary wall 38. In the exemplary embodiment, the boundary walls 36 and 38 are oriented parallel to each other. Furthermore, the retaining groove 14, in particular the vertically oriented retaining groove area 33, is bounded by a front first, vertical side wall 39, which forms a front vertical boundary wall facing the receiving space 3. In particular, this limits the cavity 37. In addition, the retaining groove 14 has a rear second, vertical side wall 40. This thus represents a rear and therefore away-facing vertical boundary wall with respect to the receiving space 3, which limits the upwardly oriented retaining groove area 33.This second side wall 40 extends vertically, in particular over its entire height. Specifically, it also limits the cavity 37 in the horizontal retaining groove area 34 on the side of the retaining groove 14 facing away from the receiving space 3.

[0191] As can be seen in Fig. 4, the vertical L-leg 32 of the coupling tab 17 dips upwards into this undercut pocket 33. A partial surface of a front face 41 (Fig. 6) of this vertical L-leg 32 then lies flat against a rear face 42 of the first vertical side wall 39 (Fig. 6). This forms the first bearing point 21.

[0192] 36 / 49

[0193] As can also be seen in Fig. 4, the coupling tab 17 rests with a bottom surface 43 (Fig. 6) of the first L-leg 31 on a top surface 44 of the lower boundary wall 36. This forms the second bearing point 22 in this direct contact area.

[0194] As can also be seen in Fig. 4, the bottom wall, and thus the lower boundary wall 36 of the retaining groove 14, extends further horizontally towards the receiving chamber 3 than would be the case for a corresponding horizontal position of the first side wall 39. The side wall 39, which delimits the upwardly oriented retaining groove area 33 towards the receiving chamber 3, is therefore arranged further away from the receiving chamber 3 than a section of the bottom wall, and thus of the lower boundary wall 36. The inner container 4, with its walls 5 to 9, also delimits a space within the housing 2, which is filled with thermally insulating material. Similarly, the wall 11 of the door 10 delimits a space 55, which is also filled with thermally insulating material. In particular, these spaces are directly delimited by the aforementioned walls 5 to 9 and 11.This is not the case for walls that are intended as retaining walls or mounting walls for food storage containers 12, which may be located in front of these walls 5 to 9, 11 and can form corresponding cladding parts. In this case, they are merely corresponding additional walls located in front of the walls.

[0195] Figure 5 shows a horizontal section along section line VV in Figure 4, illustrating the arrangement according to Figure 4 in the horizontal plane defined by the depth direction (z-direction) of the domestic refrigeration appliance 1 with the door 10 closed and in the width direction (x-direction). A section through the preferably present vertical leg 32 of the coupling tab 17 is shown. As can be seen, the retaining groove 14 in this horizontal section is also bounded on opposite sides along the longitudinal axis A by lateral boundary walls, of which only the left-hand lateral boundary wall 45 is visible in Figure 5. As shown here, this lateral boundary wall 45 is oriented obliquely with respect to a horizontal plane, in this case, with respect to the depth direction.An angle α between this inclined boundary wall 45 and the direction of depth is preferably between 10° and 30°, in particular between 15° and 25°, preferably 20°. The lateral 202303517.

[0196] 37 / 49

[0197] In this horizontal section, the boundary wall 45 is preferably oriented obliquely along its entire length. In particular, it is straight along its entire length. As can also be seen in this horizontal section when viewed from above, the first horizontally oriented L-leg 31 is also obliquely oriented at its opposite edges, or rather, it tapers from the upper end or the upper edge 30 of the base element 28 towards the vertically oriented leg 32.

[0198] Figure 6 shows a longitudinal section of the arrangement shown in Figures 4 and 5. However, unlike Figures 4 and 5, the food storage container 12 is shown here in an intermediate assembly state. It is positioned at an angle, with the coupling tab 17 already partially engaged in the retaining groove 14. The coupling tab 17 is designed to be threaded into this groove.

[0199] For the sake of clarity, only some of the reference symbols from Fig. 4 are shown in Fig. 6.

[0200] Figure 7 shows a perspective sectional view of the arrangement shown in Figures 4 to 5. Here, the assembled final state of the food storage container 12 on the wall 11, as shown in Figure 4, is again depicted. As can be seen here, the coupling tab 17, particularly with its vertically oriented leg 32, is arranged with play in the retaining groove 14, especially in the upwardly oriented retaining groove area 33. In particular, the rear side of this leg 32, facing away from the receiving space 3, is arranged without contact and at a distance from the rear second side wall 40, which forms a rear boundary wall of the cavity area 37 of the retaining groove 14.Preferably, the clear width in the horizontal direction between this rear side of the leg 32 and the inside of the boundary wall or the vertical further side wall 40 is between 50% and 150% of the thickness 46 of this vertical leg 32 in the horizontal direction.

[0201] In one embodiment, the horizontal width t1 of the vertically oriented retaining groove area 33, measured in longitudinal section, is between 4 mm and 10 mm, in particular 202303517

[0202] 38 / 49

[0203] between 5.5 mm and 8.5 mm, in particular 6 mm. In one embodiment, a horizontally dimensioned projection t2 between an end 36a (Fig. 7) of the bottom wall or the lower boundary wall 36 facing the receiving space 3 and the first side wall 39 is between 3 mm and 9 mm, in particular between 4.5 mm and 7.5 mm, in particular 6 mm.

[0204] Also measured in longitudinal section, the vertical height h1 of the vertically oriented retaining groove area 33 is between 3 mm and 9 mm, in particular between 4.5 mm and 7.5 mm, and in particular 6 mm. In one embodiment, the height h2 of the horizontally oriented retaining groove area 35, measured in the longitudinal section in the vertical direction, is between 8 mm and 16 mm, in particular between 10 mm and 14 mm, and in particular 12 mm.

[0205] In one embodiment, the radius r1 between the lower boundary wall 36 and the further vertical side wall 40 can be between 1 mm and 2 mm, preferably between 1.25 mm and 1.75 mm, particularly 1.5 mm. The radius r2 formed between a roof wall 47, which bounds the retaining groove 14 from above, and this rear further side wall 40 can be between 1.5 mm and 4.5 mm, particularly between 2 mm and 4 mm, particularly 3 mm. Preferably, the radius r2 is larger than the radius r1. In another embodiment, the radius r3 formed between the roof wall 47 and the front first side wall 39 can be between 1.5 mm and 2 mm, particularly between 1.25 mm and 1.75 mm, particularly 1.4 mm. A radius r4 formed between this front first side wall 39 and the upper boundary wall 38 is preferably between 1.5 mm and 3.5 mm. In particular, it is between 2 mm and 3 mm, and more specifically 2.5 mm.Furthermore, radii r5 and r6 can be formed. These can be formed between the wall 11 outside the retaining groove 14 and the upper horizontal boundary wall 38 on the one hand, and the bottom wall or the lower boundary wall 36 on the other. The radii r5 and r6 can be between 1 mm and 2 mm, in particular between 1.25 mm and 1.75 mm, preferably 1.5 mm.

[0206] Fig. 8 shows a perspective view of the arrangement according to Figs. 4 to 7 with the food item arranged in the assembled end position.

[0207] 39 / 49

[0208] Storage container 12 is shown. A view of the rear side 48 of wall 11, facing away from the receiving space 3, is shown here. This rear side 48 faces, in particular, a cavity filled with thermal insulation material. The correspondingly shaped boundary walls, which define the retaining groove 14, are visible. In particular, inclined boundary walls 45 are also shown at the ends opposite the longitudinal axis A of a retaining groove 14. Specifically, beveled end sections 49 are formed by the lateral boundary wall 45. As can be seen, such an inclination with an inclined boundary wall 45 is formed both in the vertically upward-oriented retaining groove area 33 and in the horizontally oriented retaining groove area 34 (compare also Fig. 12, in which the inclined boundary wall 45 of the retaining groove area 34 is shown).

[0209] Figure 9 shows a perspective view of an embodiment of a food storage container 12. In this embodiment, the support element 19 extends across the entire width of the side wall 27. In particular, the support element 19 is continuous. The height of the support element 19 is relatively small.

[0210] In Fig. 10 the food storage container 12 is shown in a perspective sectional view, the section plane being formed by the section line XX in Fig. 9.

[0211] Figure 11 shows a further embodiment of a food storage container 28 in a perspective view corresponding to Figure 9. In contrast to Figures 9 and 10, the attachment element 19 here is formed from two attachment element parts 19a and 19b. These are formed separately and distinct from one another. Here, they are integrally formed at the lower end of the side wall 27 at the end regions formed in the width direction. As can be seen in the embodiments, the attachment element parts 19a and 19b, as well as the attachment element 19 in Figure 10, are rounded at their ends opposite each other in the width direction.

[0212] 40 / 49

[0213] In one embodiment, the total contact area with which the support element 19, in particular as a bearing rib, directly abuts the support surface 18, is at most 30%, in particular at most 20%, in particular at most 10% of the total area of ​​the side wall 27. In particular, this contact area is at least 1%, in particular at least 3% of this area of ​​the side wall 27. In particular, this is the area of ​​the side wall 27 that faces this mounting wall or the wall 11. In the width direction, and thus in the horizontal direction, and thus in particular in the direction of a longitudinal axis C of the food storage container 12, the length of the support element 19 is at least 1%, in particular at least 5%, in particular at least 20%, in particular at least 30%, in particular at least 40%, in particular at least 50% of a horizontally dimensioned overlap length between the food storage container 12 and the wall 11.The mounting element 19 is formed along a vertical overlap length between the food storage container 12 and the wall 11, when the food storage container 12 is arranged against the wall 11 in its assembled final state, in a lower third of this vertical overlap length, and in particular at a lower end of this vertical overlap length. In particular, the vertical height h3 (Figs. 9 to 11) of such a mounting element 19 is between 1 mm and 30 mm, in particular between 1 mm and 5 mm, and in particular between 2.5 mm and 3.5 mm. The horizontal depth t3 (Fig. 10) of the mounting element 19 with respect to an outer surface of the side wall 27 is preferably between 0.5 mm and 3 mm, in particular between 1 mm and 2 mm, and in particular between 1.5 mm and 1.7 mm.The mounting element 19 has a strip-shaped and, in particular, flat contact surface 19c for planar contact with the mounting surface 18. The rounded design at opposite ends 50a and 50b in the width direction is shown in Fig. 9 and Fig.

[0214] 10 shown.

[0215] It is possible that the food storage container 12 is made of plastic and is, for example, an injection-molded part. It could be a two-component injection-molded part. The system element 19 could, for example, be made of PTFE. 202303517

[0216] 41 / 49

[0217] Figure 12 shows a perspective sectional view of a section of the door 10. In particular, a section of the wall 11 is shown. In this embodiment, in addition to a retaining groove 14, a separate support structure 51 is formed in the wall 11. In particular, it is integrated into the wall 11 and thus formed integrally with it. The support structure 51 is, in particular, a structure projecting from the plane of the wall 11. Here, it is located adjacent to a retaining groove 14 in the wall 11. In particular, it is designed to stiffen the retaining groove 14 and / or to stiffen a surrounding area 52 of the retaining groove 14. In this embodiment, the support structure 51 is located above the retaining groove 14 when viewed in the vertical direction of the wall 11. The support structure 51 has at least one structural element 51a.In this embodiment, the structural element 51a is designed as a straight recess in the wall 11. It is specifically designed as a straight section. It is specifically designed parallel to the retaining groove 14 in the wall 11. In this embodiment, it is specifically provided that at least one structural element 51a of the support structure 51 is designed without undercuts when viewed from a projection and thus perpendicular to the plane of the wall 11. A structural element 51a is specifically designed as an elongated and continuous section. In particular, a structural element 51a can be channel-shaped. The structural element 51a extends over a length of at least 80%, and in particular at least 90%, of the length of the retaining groove 14. In particular, such a structural element 51a extends over a length of a maximum of 120%, and in particular a maximum of 110%, of the length of a retaining groove 14.

[0218] Figure 13 shows a longitudinal section of a wall 11 having a retaining groove 14 and a support structure 51 with at least one structural element 51a. The maximum depth T of the recessed geometry of the structural element 51a, measured perpendicular to the plane of the wall 11, is preferably between 0.2 mm and 1.5 mm, particularly between 0.3 mm and 0.8 mm, and especially 0.5 mm.

[0219] As can be seen in the embodiment shown in Fig. 13, the support structure 51, viewed in this longitudinal section and thus perpendicular to the longitudinal axis of the structural element 51a, has a cornerless boundary contour 53. This contour, or boundary contour 53, can have a U-shape or a C-shape.

[0220] 42 / 49

[0221] In one embodiment, the vertical distance a1 between the upper boundary wall 38 of the retaining groove 14 and an adjacent structural element 51a arranged above the retaining groove, in particular the center point of the vertically dimensioned clear width of the entrance of the structural element 51a, is between 10 mm and 50 mm, in particular between 20 mm and 30 mm, in particular 25 mm. In particular, the vertically dimensioned clear width of an entrance 54 of a structural element 51a is at most one-fifth, in particular at most one-tenth, of the clear width of an entrance or entrance area 35 of the retaining groove 14. In particular, the support structure 51 is designed without contact and thus adjacent to the retaining groove 14 in the wall 11.

[0222] A maximum depth T of a structural element 51a of the supporting structure 51, measured perpendicular to the plane of the wall 11, is at most one tenth, in particular at most one twentieth, of a maximum depth T1 of the retaining groove 14, measured perpendicular to the plane of the wall 11.

[0223] In the exemplary embodiments, it is shown that the retaining groove 14 is integrated into a wall 5 to 9, 11 and thus formed integrally with it. In another exemplary embodiment, it is also possible that a retaining groove 14 is formed in an adapter that is separate from a wall and the container 12. Such an adapter can be detachably attached to a separate wall. 202303517
