Description

Refrigerating appliance with a shelf

The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising an inner container equipped with heat-insulating material, which has a rear wall and two, a cooling Kühlgutlagerraum laterally delimiting, opposite inner walls which have at least one pair of support ribs for supporting a shelf, of which at least one Supporting rib has a holding means which is positively connected in a supported by the support ribs position of the shelf with a counter-holding means of the shelf to secure the shelf against horizontal displacement of the shelf on the support ribs.

DE 10 2007 016 072 A1 describes a refrigerator comprising a main body with a storage compartment, wherein the storage compartment has an inner wall, a storage unit which divides the storage compartment, and a storage holder, which is provided on the inner wall of the storage compartment, removably with the storage unit is connected and has a recess, wherein the storage unit comprises a panel and at least one stopper which is removably connected to the panel and received in the recess to limit movement of the panel in a longitudinal direction of the shelf support. The object of the invention is to provide a refrigeration device in which a shelf can be easily removed from the refrigerator or inserted into the refrigerator and is held securely in its inserted position.

A refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge-freezer or a wine storage cabinet.

The object is achieved by a refrigeration device, in particular domestic refrigeration appliance, comprising an inner container equipped with heat-insulating material, which laterally delimits a rear wall and two, a coolable refrigerated goods storage space. zende having opposite inner walls, which have for storage of a shelf at least a pair of support ribs, of which at least one support rib has a holding means which is positively connected in a supported by the support ribs position of the shelf with a counter-holding means of the shelf to the shelf against to secure a horizontal displacement of the shelf on the support ribs, wherein the inner container has at least one receptacle into which at least a portion of a rear edge of the shelf facing the rear wall can be inserted. The support ribs may in one embodiment be formed by ledges projecting from the left and right side walls of the inner container. In another embodiment, the support ribs may be formed by the upwardly facing surfaces of grooves formed in the left and right sidewalls of the inner container, ie, receding into the depth from the surface of the left and right sidewalls.

Instead of a single pair of supporting ribs, which may be arranged, for example, immediately above a vegetable tray inserted into the refrigerating appliance on the bottom of the inner container, a plurality of pairs of supporting ribs can be arranged one above the other at intervals, in particular at regular intervals from each other. As a result, the shelf can be used optionally at different heights in the refrigerator. It can also be used at the same time in the refrigerator several shelves. The shelf can be formed at least in sections by a grid, in particular a metal grid or metal grid and / or at least partially have a glass plate. The shelf may, in particular be provided or overmoulded as a glass plate with a plastic edge, in particular provided with a frame-like circumferential around the shelf plastic edge or be encapsulated. The one or more holding means may in particular be attached to such a plastic edge or integrally formed therewith.

The retaining means may be formed by a downwardly projecting tab or pin. The holding means or the tab or the pin can in its outer contour be adapted to the inner contour of the counter-holding means, in particular outer contour and inner contour may have the same shape with slightly different sizes.

By the inner container having at least one receptacle into which at least a portion of the back wall facing the rear edge of the shelf is inserted, the shelf is in addition to its protection against horizontal withdrawal in addition to lifting in a rear portion of the shelf and / or against tilting in a secured from the rear wall to the front sloping angular position. In addition, the compartment can be secured by the at least one receptacle alternatively or additionally against lateral tilting or one-sided lateral lifting.

A lifting and / or tilting of the shelf can be avoided in particular because otherwise there is a risk that is pressed by lifting and / or tilting the shelf, the at least one holding means from the counter-holding means and consequently the shelf is no longer secured against horizontal withdrawal is.

This circumstance may occur, for example, when the shelf is positioned directly above a Schublandeartigen extract, such as a vegetable dish. If the Schublandeartige extract or the vegetable bowl is filled beyond its upper edge, for example, by large-scale vegetables such as cabbage, pumpkins, melons, etc., it may happen that the user the Schublandeartige extract or the vegetable dish into the refrigerator after loading back into it pushes, whereby the projecting beyond its upper edge part of the goods to be cooled pushes the shelf from bottom to top. Depending on the position of the part of the cooling material that projects beyond its upper edge, the shelf is tilted forwards and / or tilted to the side. In this case, if appropriate, the at least one holding means can be pressed out of the counter-holding means, whereby the shelf is no longer secured against horizontal withdrawal. If now the user pulls out the Schublandeartigen extract or the vegetable bowl again, unintentionally also the shelf is pulled along. Thus, there is a risk that the shelf accidentally falls out of the refrigerator. With at least one receptacle according to the invention, in which at least a portion of the rear wall facing the rear edge of the shelf can be inserted, it can be prevented that the shelf tilted forward and / or tilted to the side, causing the shelf no longer unintentionally pulled can be. The same applies if a large refrigerated goods is forced between two shelves, which is greater than the distance between the two shelves, so that the upper shelf is raised by the underlying refrigerated goods. The at least one receptacle can be arranged near the rear wall and / or on the rear wall of the inner container. The at least one receptacle can be arranged in particular on one or both side walls of the inner container near the rear wall. If appropriate, the at least one receptacle can extend over a corner region between the side wall and the rear wall. The recording can also extend over the entire width of the rear wall. The receptacle can also extend laterally forward, ie, away from the rear wall along the side walls, to the vicinity of the holding means or the counter-holding means.

The at least one receptacle may alternatively or additionally be arranged on an end of the support rib facing the rear wall of the inner container. In this respect, the receptacle can embrace an edge of the shelf, namely a side edge on a side rear section and / or a rear edge on a rear edge of the shelf. In all embodiments of the invention, the at least one receptacle can be formed at least partially by a projection on the inner wall and / or the rear wall of the inner container and the support rib. Alternatively, the projection may be attached as a separate component to the inner wall and / or the rear wall of the inner container. The projection bounds the shelf from one side, wherein the shelf can be limited from the other side by the support rib. The projection and the support rib so far form two opposite boundary walls of the recording. The two opposite boundary walls are arranged spaced apart from each other such that the shelf is accommodated depending on its wall thickness therebetween.

The projection and / or the support rib can be formed by a wall molding of the inner container which is produced in the refrigerated goods storage space by means of a deep drawing process. In all embodiments according to the invention, a projection on the inner wall and / or the rear wall of the inner container and the support rib can have a receiving groove for the shelf limit, which extends at least over a partial section along at least one of the two side edges of the shelf.

The receiving groove can extend over a length between 20% and 5%, in particular between 15% and 10% of the depth of the shelf, starting from the rear wall of the inner container to the front. In this case, the at least one holding means or the least one counter-holding means may be arranged in a central region of the side edge of the shelf or in a central region of the depth of the side wall of the inner container. In particular, the at least one retaining means or the least one counter-holding means in a central region of the side edge of the shelf can be placed closer to the rear wall or offset closer to the rear wall in a central region of the depth of the side wall of the inner container.

Starting from the rear wall of the inner container, the receiving groove can be designed to widen in the groove width towards the front. This means that the receiving groove has a smaller groove width in a region closer to the rear wall than in a front region, i. in a more remote from the rear wall area in which the groove width is greater. Thus, a tilting or lifting of the shelf is facilitated in intentional removal of the shelf.

In all embodiments according to the invention, at least one receptacle on the left side wall and at least one further receptacle on the right side wall of the inner container can be formed. In a feed position, the shelf can be supplied for example by the fact that the shelf is placed with its trailing edge on the Tragrip- pen and the shelf is inserted in the direction of the rear wall in the inner container. In this case, the shelf is not in any horizontal orientation, but is employed at least at an angle in the direction of the rear wall sloping that the at least one downwardly projecting counter-holding means is located above the support ribs or at most slides on the support ribs. The trailing edge of the shelf is in the receiving groove. inserted between the projection and the support ribs.

In an insertion position, the trailing edge of the shelf is already inserted into the receiving groove, ie between the projection and the support ribs. The shelf is then already partially lowered, ie less inclined at an angle in the direction of the rear wall than in the feed position, such that the at least one downwardly projecting counter-holding means already engages at least partially into the holding means, ie a recess on the support ribs or against horizontal withdrawal already is secured.

In a use position, the trailing edge of the shelf is completely into the receiving groove, i. inserted between the projection and the support ribs. The shelf is completely lowered, i. no longer inclined at an angle in the direction of the rear wall, but in a horizontal position. In the horizontal position, the downwardly projecting counter-holding means fully engages the holding means, i. a recess on the support ribs and the shelf lies flat on the two support ribs. In this use position, the shelf is secured against horizontal displacement, in particular by the intermeshing of holding means and counter-holding means. In addition, the shelf is secured against tipping forward, i. secured against lifting of the trailing edge of the shelf from the support ribs, in particular by the at least one projection.

In all embodiments according to the invention, at least one receptacle may be formed on the support rib and another receptacle on the rear wall of the inner container. The at least one receptacle can extend in particular over the entire width of the rear wall.

All the recordings described can be formed repeatedly at different heights on the inner container. Thus, a shelf can be worn either at different altitudes of the refrigerator by means of an inventively designed recording or inventively designed recordings.

In summary, in other words, be equipped according to the invention on a support rib of the inner container of a refrigerator with a short groove. The groove can be tightened on the inner container, ie formed, for example, by deep drawing. Depending on the design of the shelf or the glass plate variant, for example, a pin engage in an encapsulation or on a guide bar in the groove. This prevents unwanted extraction of the shelf or the glass plate. An am Inner container tightened cam can prevent lifting of the shelf or the glass plate in a rear area. To mount the shelf or the glass plate can be made slightly upwards, placed on the rib and pushed backwards. Subsequently, the shelf or the glass plate can be drained front. Shooting the shelf or the glass plate is then in the correct position, ie in the operating position.

In refrigerators a shelf, such as a glass plate should be kept safe. The shelf or the glass plate can be fixed, for example, above a vegetable dish. With the embodiments according to the invention, one or more of the following requirements can be met. The glass plate should not be able to be pulled out without it being clearly lifted off the support surface. Depending on the equipment variant different glass plate designs can be positioned and held by a similar fixation, a fixation can be designed so that the equipment-dependent shelves or glass plates can be used in different refrigerators. As a result, the glass plate variance can be kept small. In particular, a removal of the glass plate should be possible for a customer with little effort. Simple installation of the shelf or the glass plate can be realized. A transport safety of the glass plate can be achieved as far as possible by the fixation. A packaging effort can be minimized because inserts and withdrawals can be omitted.
