Description

One aspect of the invention relates to a household refrigeration appliance with an inner container. The inner container has walls. The household refrigeration appliance also has at least one storage space for food. This is limited by walls of the inner container. Furthermore, the domestic refrigeration appliance has at least one rail, which is intended to accommodate a separate food storage container or is designed accordingly. The rail is held on a wall of the inner container with at least one snap connection. A further aspect of the invention relates to a method for mounting a rail on a wall of an inner container of a household refrigeration appliance.

The attachment of separate rails to walls of an inner container is known. Such rails can usually be arranged on vertical side walls of an inner container. They are intended to allow a food receptacle to be placed thereon and to be moved relative thereto. For example, the food storage container can be pushed into or pulled out of the storage space on the rail in the depth direction of the household refrigeration appliance. Such a food storage container can have a tray, for example.

For example, such from the EP 3 155 337 B1 known. However, the attachment of this rail is impaired there. On the one hand, a relatively complex assembly scenario is required, on the other hand, the position-fixed arrangement of the rail in the assembled end state is only possible to a limited extent.

It is the object of the present invention to create a household refrigeration appliance and a method in which a rail for storing a food storage container can be arranged in an improved manner on a wall of an inner container.

This object is achieved by a household refrigeration appliance and a method according to the independent claims.

One aspect of the invention relates to a household refrigeration appliance. This household refrigeration appliance has an inner container. The inner container has walls. Furthermore, the household refrigeration appliance has at least one storage space for food. This receiving space is limited by walls of the inner container. In addition, the household refrigeration appliance has at least one separate rail. This rail is designed to accommodate a separate food receptacle. The rail, which is separate from the inner container, is held on a wall of the inner container with at least one snap connection. In addition to this at least one snap connection, the rail is designed with at least one positioning element. This at least one positioning element of the rail rests against a supporting part of the wall in the assembled final state of the rail on this wall in a prestressed manner. As a result, a prestressed connection is formed. In the assembled end state, the rail is therefore also arranged on the wall with such a prestressed connection in addition to the snap connection. This enables the rail to be arranged in a more fixed position on the wall. Undesirable position tolerances or rattling of the rail in the final assembled state can be avoided in this way. Last but not least, this also improves the intended mounting of a food receptacle on this rail. As a result, the movement of the food receptacle relative to the rail can also be improved. A jam-free and smoother movement of this food storage container on the rail is thereby made possible. Last but not least, the mechanical stability can also be increased by such a position-fixed attachment of the rail to the wall. This also improves the absorption of forces by this rail.

In one embodiment, this preload created by the preload connection acts in the direction of the longitudinal axis of the rail. In particular, the longitudinal axis of the rail is oriented in the depth direction of the household refrigeration appliance. Due to this specific orientation of the prestressing, and thus also the correspondingly generated prestressing force, the position in this depth direction can be set and maintained more precisely. A possible positioning with undesired play in this depth direction is thereby avoided. This makes it possible for the rail to be arranged in a particularly fixed position and, in particular, not to move in this depth direction when a food receiving container is displaced in this depth direction.

In addition, the assembly scenario is also simplified by such a design of the rail and its different types of fastening. In particular, in this context, the prestressed connection can be used as the first connection to be generated in the assembly scenario, in order to then also use the other connections, in particular at least one Snap connection to build and produce below.

In one embodiment, the positioning element is oriented laterally to the longitudinal axis of the rail. In one exemplary embodiment, this positioning element is a freely cantilevered tab. This means that the positioning element does not extend with its main extension direction in the direction of the longitudinal axis of the rail. Rather, it is oriented laterally protruding from it. This makes attachment to the wall of the inner container easier. In particular, a simple assembly scenario can thus also be made possible. This is because such an exposed configuration of a positioning element can enable simple threading into a receptacle in the wall, so that a corresponding pre-coupling is already made possible here. This also to the effect that the prestressed connection is not set in its final functional position. Due to the design as a freely cantilevered tab, this threading principle is made possible in a particularly smooth-running and user-friendly manner. A targeted generation of this pre-assembly position is also achieved as a result.

In one embodiment, the positioning element is arranged at one end of the rail. In particular, this is the rear end of the rail as viewed in the depth direction. This particularly benefits the advantages mentioned above. Because this enables a simple introduction scenario for the positioning element into a receptacle in the wall. As a result, the further assembly steps can be made easier for a user. In addition, the directional prestress can then also be defined and generated as desired. It then acts forward to a particular extent from this depth direction, so that the rail is prestressed horizontally forward in this depth direction.

In one embodiment, the positioning member is formed in a plate shape. This plate shape is oriented in particular vertically. This means that the positioning element has larger, in particular much larger, dimensions in the height direction and in the width direction of the household refrigeration appliance than in the depth direction. This further improves the advantages mentioned above. In particular, a relatively large-area contact of the positioning element on the support part can be achieved by this design and orientation. As a result, a high mechanical stability of the prestressed connection can also be achieved and a corresponding prestress or a prestressing force can be generated in a very directed manner. Last but not least, this configuration also enables simple threading and coupling with the support part. A positionally fixed arrangement and the maintenance of this positionally fixed state are also possible in an improved manner as a result.

In one exemplary embodiment, the positioning element in a basic position, viewed in a horizontal plane, is inclined at an angle of between 45° and less than 90°, in particular between 45° and 70°, to the longitudinal axis of the rail. This is another very advantageous embodiment. On the one hand, this allows the rail to be threaded in and supported in a particularly user-friendly manner. In particular, when the rail is oriented in a pre-assembled state with its longitudinal axis in a horizontal plane at an angle to the depth direction of the household refrigeration appliance. Last but not least, the prestressed connection can also be achieved particularly advantageously by this configuration. This is because the desired preload can also be set in a very defined and targeted manner. In particular, the positioning element is in this respect also a freely cantilevered, elastically resilient tab. This enables a particularly effective prestressed connection.

In one embodiment, the snap connection is only located locally in a front third of the length of the splint. As a result, a specific mechanical connection can be provided locally in this front area. Diverse snap connections formed at the most varied of locations are therefore no longer necessary. This also simplifies the assembly scenario. The assembly scenario and the position-fixed bracket can be improved precisely in the operative connection of the snap connection on the one hand and the prestressing connection on the other hand and their local positions on the rail. Snap connections are no longer formed at a variety of individual points over the entire length of the rail, which then may have to snap together in a complicated and clamping manner during assembly. Rather, this explained new concept improves the simplification of the rail geometry and the resulting handling during assembly.

In one embodiment, the rail has a hollow cylinder. At least one snap element is formed integrally in its cylinder wall. In particular, this snap element is resilient perpendicular to the longitudinal axis of the hollow cylinder. By configuring the rail with such a hollow cylinder, a targeted coupling of the rail with a corresponding receptacle in the wall can be achieved on the one hand. This also allows for some pre-centering and demonstration when mounting the rail to the wall at that local location. On the other hand, this hollow cylinder then also serves in a further function as a carrier for the snap element. With that can a very targeted snapping of the snap element in the receptacle on the wall can also be achieved. Last but not least, such a specification of a hollow cylinder creates a mechanically stable component which, on the other hand, is lighter because of the hollow structure. In particular, this also advantageously enables the spring option of this at least one snap-in element.

In one embodiment, the longitudinal axis of the hollow cylinder is oriented perpendicular to the longitudinal axis of the rail. This also improves the overall concept with regard to the geometric configuration of the rail and the assembly scenario. In particular, both longitudinal axes are oriented in a horizontal plane, in particular when the rail is mounted.

In one embodiment, at least two snap elements are formed in the cylinder wall. In particular, these are separate snap elements. In one exemplary embodiment, these snap-in elements are arranged offset from one another by 180°, viewed in the direction of rotation around the longitudinal axis of the hollow cylinder. In particular, the direction in which the snap element can spring is the direction of the longitudinal axis of the rail. This also enables a simplified snapping scenario. In particular, this advantageously supports the holding of the rail in a fixed position. Precisely when two such snap-on elements are present, which act in a correspondingly resilient manner in the direction of the longitudinal axis of the rail, this position-fixed mounting of the rail on the wall can be further improved.

In one embodiment, the snap-in elements are arranged with their free ends in different axial positions in the direction of the longitudinal axis of the hollow cylinder. As a result, the position-fixed mount can be further improved. Assembly tolerances and manufacturing tolerances can thus be evened out even better.

In one embodiment, a backing part is arranged on the wall of the inner container on which the rail is to be arranged. The backing part has a blind hole-like depression. In particular, the backing part is a component that is separate from the wall. The hollow cylinder is inserted into this blind-hole-like depression when the rail is mounted on the wall. In particular, the snap element of the rail is then snapped onto a counter-snap element which is formed on the wall of the depression. The recess wall thus has, in particular, an integrated counter-snapping element. This snaps into place with the snap-in element of the rail.

As a result, the snap connection is also arranged in a quasi-protected or hidden manner. This to the effect that the hollow cylinder dips into this depression. This also forms a guide during assembly.

In one embodiment, the rail has at least one height adjustment element. With this, the height of the rail can be adjusted during assembly. In particular, this also means that the desired height is set automatically during assembly. An automatic adjustment or setting of the correct height of the rail relative to the wall is thus already made possible during the installation itself. A vertical direction in this regard is the vertical direction of the household refrigeration appliance. This also simplifies the assembly scenario and still improves the exact location and positioning of the rail. In particular, this also improves the position-fixed arrangement of the rail on the wall.

In one embodiment, the height adjustment element has a plate-like tab. In one exemplary embodiment, this plate-like tab projects from an elongate base part of the rail transversely to the longitudinal axis of the rail, in particular in a freely cantilevered manner. The height adjustment element engages in a socket formed in the wall of the inner container. This height adjustment element is coupled to an adjustment wall in the mount, so that the height of the rail is adjusted relative to the mount. In particular, this altitude is then also kept fixed. This configuration achieves a concept that is simple and reduced in terms of components, with which the exact vertical position of the rail can be adjusted in an improved manner. In particular, this is then also automatically achieved during assembly of the rail.

In one exemplary embodiment, the rail has a plurality of separate height adjustment elements at a rear end viewed in the direction of its longitudinal axis. These are in particular arranged parallel and spaced apart from one another. This allows the altitude setting to be further improved. In particular, this achieves an even more precise height adjustment. As a result, simple manufacturing tolerances of the components can also be compensated for.

Another aspect of the invention relates to a household refrigeration appliance. This has at least one food receptacle according to the aspect mentioned above or an advantageous embodiment thereof. The household refrigeration appliance can be a refrigerator or a freezer or a fridge-freezer combination appliance. The household refrigeration device may have a housing. This has an outer housing. A separate inner container is accommodated in the outer housing. The walls of the inner container delimit at least one receiving space of the household refrigeration appliance. The receiving space can be a cold room or a freezer room. For this purpose, the food receiving container is a separate component that can be arranged in this receiving space. The food storage container can also be removed from this storage space as a whole. It is also possible that, in addition to or instead of this, only the shell of the food receptacle can be removed. This can also be pulled out and pushed in in the depth direction of the household refrigeration appliance.

A further aspect of the invention relates to a method for mounting a rail on a wall of an inner container of a household refrigeration appliance. The household refrigeration appliance can be designed according to the above-mentioned aspect or an advantageous exemplary embodiment thereof.

• - Einführen des Positionierelements in eine Aufnahme in der Wand des Innenbehälters;
• - Andrücken des Positionierelements an das Abstützteil, so dass das Positionierelement in Tiefenrichtung des Haushaltskältegeräts vorgespannt wird,
• - Schwenken der Schiene hin zur Wand an einem Ende, welches dem Ende gegenüberliegt, an dem die Vorspannverbindung, die durch das Positionierelement und das Abstützteil gebildet wird;
• - Automatisches Verschnappen der Schnappverbindung beim Schwenken der Schiene in die Endposition.

The method has the following steps in particular:

• - Inserting the positioning element into a receptacle in the wall of the inner container;
• - pressing the positioning element onto the support part, so that the positioning element is prestressed in the depth direction of the household refrigeration appliance,
• - pivoting the rail towards the wall at an end opposite to the end at which the prestressing connection formed by the positioning element and the support part;
• - Automatic snapping of the snap connection when swiveling the rail into the end position.

A simple assembly scenario is thus achieved. The rail can be attached to the wall in a fixed position.

In 1 an exemplary embodiment of a household refrigeration appliance 1 is shown in a schematic representation. The household refrigeration appliance 1 can be designed for storing and preserving food. The domestic refrigeration appliance 1 can be a refrigerator or a freezer.

The domestic refrigeration appliance 1 has a housing 2 . This housing 2 has an outer housing 3 . The outer housing 3 can be made of metal, for example. For example, it can be made of sheet metal.

The household refrigeration appliance 1 also has an inner container 4 . The inner container 4 is separate from the outer housing 3 . The inner container 4 is accommodated in the outer case 2 . The inner container 4 can in particular be made of plastic. The walls of the inner container 4 delimit a receiving space 5 of the household refrigeration appliance 1. The receiving space 5 is intended to receive food. The receiving space 5 can be a freezer compartment or a refrigerator compartment, for example.

The inner container 4 has a top wall 6, a bottom wall 7, a rear wall 8 and vertical side walls 9 and 10 as walls. Furthermore, the domestic refrigeration appliance 1 has a door 11 . The door 11 is shown here in the open state. It is movably arranged on the housing 2 . The door 11 is provided for closing the receiving space 5 at the front.

In addition, in 1 an embodiment of a food receptacle 12 is shown. This can be a shell or at least have a shell. The food accommodating container 12 is arranged in the accommodating space 5 . It is movably positioned therein in this regard. In particular, it can be pulled out and pushed in in the depth direction (z-direction) of the household refrigeration appliance 1 .

For this purpose, a first rail 13 and an opposite second rail 14 are provided in the exemplary embodiment. The two rails 13 and 14 here in the exemplary embodiment are arranged on the insides of the opposite vertical side walls 9 and 10 . Rails 13 and 14 are separate components from walls 9 and 10.

In one exemplary embodiment, they are arranged on these side walls 9 and 10 so that they can be detached without being destroyed. These rails 13 and 14 are intended to accommodate the food receptacle 12 . This food accommodating container 12 is therefore supported on these rails 13 and 14 . The rails 13 and 14 are arranged in a stationary manner on the vertical side walls 9 and 10 .

In 2 an embodiment of the rail 14 is shown in a perspective view. The rail 14 is preferably formed in one piece. The rail 14 is in particular made of plastic. It can be an injection molded component, for example. The rail 13 is designed in particular in accordance with the rail 14 .

The rail 14 has a longitudinal axis A. This is oriented in the installed state of the rail 14 on the vertical side wall 10 in the depth direction.

The rail 14 has a base part 15 . The base part 15 is designed as an elongate part. It is hollow in the embodiment. The rail 14 has a first end 16 . This first end 16 is a front end here. Viewed in the direction of the longitudinal axis A, the rail 14 has a second end 17 . In particular, this is a rear end 17 . In the exemplary embodiment, the base part 15 preferably has struts 18 . For the sake of clarity, only some of these struts 18 are provided with the reference number. They serve to stiffen the base part 15, which is hollow here.

These struts 18 are preferably C-shaped plate parts.

The base part 15 has an upper wall 19 in the height direction (y-direction) of the household refrigeration appliance 1 . The top wall 19 has a front surface portion 19a. This is designed in particular as a strip. In particular, it is flat. In this regard, this surface area 19a extends in a horizontal plane. This is spanned by the width direction (x-direction) and the depth direction (z-direction) of the household refrigeration appliance 1 . A second surface area 19b is then formed towards the rear. This is lowered in the vertical direction (y-direction) compared to the surface area 19a. The rear surface portion 19b is also curved. In this regard, it is formed as a concave surface strip. It ends at the rear end 17. In one embodiment, the surface areas 19a and/or 19b are support surfaces for the food receptacle 12.

In addition, a stop element 20 is integrated at the front end 16 of the rail 14 . This is raised upwards in the height direction compared to the surface area 19a adjoining it directly to the rear. In particular, is through this stop element 20 also forms a pull-out stop for the food receptacle 12 . Furthermore, the rail 14 has a roof 21 . This is offset in the height direction relative to the top wall 19 of the rail 14 upwards. As a result, a guide between the wall 19 and the roof 21 is also formed. The food receiving container 12 can extend into this intermediate space with a guide element. This enables the food receptacle 12 to be guided accordingly on the rail 14 .

As can be seen, the base part 15 is open on the side facing the vertical side wall 10 to which the rail 14 is attached. On the side facing away from this vertical side wall 10, the base part 15 is closed.

The rail 14 has a hollow cylinder 22 . The hollow cylinder 22 is formed on the base part 15 . The hollow cylinder 22 has a longitudinal axis B. This is oriented horizontally here. It is oriented perpendicular to the longitudinal axis A. When the rail 14 is installed, the longitudinal axis B is oriented in the width direction (X-direction) of the household refrigeration appliance 1 . The hollow cylinder 22 has a cylinder wall 23 . In this cylinder wall 23, a snap element 24 is integrally formed. In addition, a second snap-in element 25 is formed integrally in this cylinder wall 23 in the exemplary embodiment. The snap elements 24 and 25 are designed as resilient tabs. You are here in the direction of rotation about the longitudinal axis A by 180 ° to each other. The position of these snap elements 24 and 25 is such that they spring in the direction of the longitudinal axis A. Provision can be made for the snap-in elements 24 and 25 to be arranged in the same axial position when viewed in the direction of the longitudinal axis B. In one exemplary embodiment, it is also possible for the two snap-in elements 24 and 25 to be arranged in different axial positions in the direction of the longitudinal axis B. This applies in particular to the free ends 24a and 25a of the snap elements 24 and 25.

In one exemplary embodiment, it is also possible for counter-snapping elements, which are arranged externally to the rail 14 and with which the snapping elements 24 and/or 25 are intended to snap, to be formed in different axial positions in the direction of this longitudinal axis B. This configuration makes it possible for manufacturing tolerances of the components to be compensated for, and by snapping one of the snap elements 24 and/or 25 with a counter-snap element with a precise fit then supports a positionally fixed arrangement of the rail 14 on the vertical side wall 10 .

As moreover in 2 As can be seen, the rail 14 has at least one positioning element 26 . When the rail 14 is in the installed final state, the positioning element 26 rests against a support part of the vertical side wall 10 and it is intended that it rests prestressed on this support part. As a result, a pretensioning device of the household refrigeration appliance 1 is then formed between the positioning element 26 and the support part. A prestressed connection is created by these components.

As in 2 as can be seen, this positioning element 26 is formed on the rear end 17 . The positioning element 26 is designed here as a freely cantilevered tab. The positioning element 26 can also be referred to as a tongue. The positioning member 26 has a plate shape. This is oriented vertically. In a basic position of this positioning element 26, as shown in 2 is shown, the positioning element 26 is inclined at an angle of between 45° and less than 90°, in particular between 45° and 70°, to the longitudinal axis A when viewed in a horizontal plane (xz plane). In particular, it is inclined in such a way that it faces away from the front end 16 of the rail 14 or is inclined away from it at an angle. The positioning element 26 is designed to be elastically springy.

In one exemplary embodiment, the rail 14 also has at least one height adjustment element 27 . With this height adjustment element 27, the height of the rail 14 can be adjusted during assembly relative to the side wall 10, in particular automatically. The height adjustment element 27 is designed as a plate-like tab. This cantilevers freely from the base part 15 of the rail 14 transversely to the longitudinal axis A of the rail 14 . In the exemplary embodiment, several height adjustment elements are formed here. For example, more than two height adjustment elements, for example three height adjustment elements 27, 28 and 29, can be provided. These are oriented here as parallel, plate-like tabs. Viewed in the direction of the longitudinal axis A, they are oriented in series with one another and spaced apart from one another. As can be seen, these height adjustment elements 27 to 29 are formed in the rear end area of the rail 14 . They are oriented further forward than the positioning element 26. In particular, these plate-shaped orientations are designed such that the respective plate plane is oriented perpendicular to the longitudinal axis A.

In 3 a partial area of the household refrigeration appliance 1 is shown in a perspective view from the front. A partial area is shown here, in which the rail 14 can be seen. Rail 14 is this shown with respect to the side wall 10 in its final position.

As can be seen, a backing part 30 is arranged on the side wall 10 . The backing part 30 is in this context in an intermediate space 31 ( 1 ) between the outer housing 2 and the inner container 4 arranged. Thermally insulating material, for example insulating foam, is usually introduced into this intermediate space 31 . The backing part 30 is thus in particular surrounded by this insulating material.

In one exemplary embodiment, the backing part 30 has a blind-hole-like depression 32 . The hollow cylinder 22 dips into this depression 32 . The depression 32 has on its depression wall 33 the already mentioned counter-snapping elements 34 and 35 ( 6 ) on. The snap elements 24 and 25, in particular with the free ends 24a and 25a ( 6 ), snap. As can be seen, viewed in the direction of the longitudinal axis A, the hollow cylinder 22 is formed in a front third of the length of the rail 14 . In particular, a corresponding configuration of a snap connection is only provided in this front third of the length. In particular, the rail 14 otherwise has no further snap connections.

In 4 is the arrangement according to FIG 3 shown. As can also be seen here, the side wall 10 has a receptacle 36 . The receptacle 36 can also be designed as a blind hole-like trough. It can also be a deposit part. However, it can also be designed in one piece and thus integrally with the vertical side wall 10 . The positioning element 26 dips into this receptacle 36 in the installed final state of the rail 14 . In particular, the height adjustment elements 27 to 29 that are preferably present also dip into it.

In 4 the receptacle 36 is shown transparently in this context. The position of the positioning element 26 on a support part 37 can thus be recognized. The support part 37 is a wall area of the receptacle 36. This support part 37 is oriented correspondingly obliquely, so that the positioning element 26 can rest against it over as large an area as possible. Likewise are in 4 the three height adjustment elements 27 to 29 shown here as examples can be seen due to the transparent representation of the receptacle 36 .

In 5 is in this context a horizontal sectional view of the arrangement according to FIG 3 and 4 shown. In this regard, a sectional view along the section line VV in 3 shown. The arrangement of the positioning element 26 and the support part 37 forms a prestressed connection 38 .

In 6 is an enlarged representation of the sectional view in FIG 5 shown. In this regard, the front portion of the assembly is shown enlarged.

In 7 the rail 14 is shown in section. A horizontal sectional view is shown here. This representation is a sectional image that is stepped in the vertical direction, in which the front region of the arrangement according to 3 the section plane is drawn above the stop element 20 and in the rear area the section plane below the section line VV in 3 is pulled, namely is pulled through the receptacle 36. As a result, the positioning element 26, the support part 37 and the several height adjustment elements 27 to 29 in this case are 7 also shown in section.

In 8th is in this context the rear part of 7 shown enlarged. The prestressed arrangement of the positioning element 26 on the support part 37 can be seen. This creates a defined preload in the direction of the longitudinal axis A. In particular, a prestress is also generated in two spatial directions to compensate for tolerances in the length and thus in the direction of the longitudinal axis A and in contact with the wall region that is formed by the support part 37 .

In 9 in contrast, the rear end is according to 8th in one to 8th vertical sectional plane shown. In 9 a vertical plane is thus formed as the cutting plane. This is spanned by the depth direction and the height direction. In particular, the framework-like structure of the struts 18 can also be seen here in one exemplary embodiment. As in 9 can also be seen, the exact height position of the rail 14 is formed by the height design of the height adjustment elements 27 to 29, in particular also for the recess or for the receptacle 36. This also enables the rail 14 to be arranged in a very aligned, horizontal and position-fixed manner.

When the rail 14 is installed, the positioning element 26 is first inserted into the receptacle 36 . The positioning element 26 is then applied to the support part 27 . In this regard, the rail 14 is then oriented with its longitudinal axis A at an angle to the depth direction of the household refrigeration appliance 1 . This means that the front end 16 of the rail 14 is still positioned well away from the vertical side wall 10 . Due to the pre-assembly position formed in this way, a pivoting of the rail 14 towards the vertical side wall 10 is then carried out in the further assembly process, in particular others at the front end 16. The coupling between the positioning element 26 and the support part 37 then also serves as a pivot bearing here. With the pivoting of the front end, the snap connection 39 between the snap elements 24 and/or 25 with the counter snap elements 34 and/or 35 is then also automatically achieved. Due to the specific configuration of the prestressing connection 38, the defined prestressing in the depth direction is then also automatically achieved and the prestressing force is generated in this axial direction in order to support a position fixing of the rail 14 in this respect.

In 9 adjustment walls 40 and 41 can also be seen. These are in particular an upper and a lower boundary wall of the receptacle 36. At least one height adjustment element 27, 28 and 29 can be in contact with at least one of the adjustment walls 40, 41 with an upper edge and/or with a lower edge. As a result, the vertical position of the rail 14 is precisely set, in particular at least at the rear end 17 .
