Description

The invention relates to a housing for a household refrigerating appliance, with an outer wall and an inner wall which is arranged at a distance from the outer wall, and a gap formed between the outer wall and the inner wall, in which at least one vacuum insulation element is arranged at a distance from the outer wall and the inner wall. Furthermore, the invention relates to a household refrigerator with such a housing.

From the DE 10 2009 060 079 A1 is a refrigerator or freezer with an inner container and the inner container at least partially enveloping wall known. A space between the inner container and the wall is provided with at least one vacuum insulation panel disposed in the space and a foam material surrounding the vacuum insulation panel. The Vakuumisolierpaneel is spaced by means of spacers mounted on the inner container.

In addition, from the DE 10 2009 041 914 A1 a door or flap for a refrigerator and / or freezer known. The inner door is contoured and has a plurality of superimposed or juxtaposed depressions. On the inside of the inner door, one or more vacuum panels are glued directly. These have a contouring that corresponds to the negative of the contouring of the inside of the inner door.

It is an object of the present invention to provide a housing for a household refrigerator and such a household refrigeration appliance, in which an improved in terms of insulation effect attachment of a vacuum insulation element is achieved and beyond no undesirable deformations occur on the visible outer wall of the household refrigerator and the housing ,

This object is achieved by a housing and a household refrigerator according to the independent claims.

An inventive housing for a household refrigerator comprises an outer wall and an inner wall, which is arranged at a distance from the outer wall. Between the outer wall and the inner wall, a gap is formed, in which at least one vacuum insulation element is arranged at a distance from the outer wall and the inner wall. The at least one vacuum insulation element is connected to at least one retaining element, wherein the retaining element is connected to at least one housing wall. The retaining element is arranged embedded in a recess of the vacuum insulation element on an outer side of the vacuum insulation element facing an inner side of the outer wall. By such a configuration by means of its own separate retaining element, an improved attachment of the vacuum insulation element can be spaced apart from the outer wall and the inner wall in the intermediate space. In addition, achieved by such a specified attachment of the retaining element on the inner wall side facing that occur in the finished state of the housing no undesirable deformation of the outer wall.

The housing is in particular the outer housing of the household refrigerator and the outer wall is in particular the outer wall of the household refrigerator.

It is preferably provided that the holding element is arranged on the outside of the vacuum insulation element completely in the recess. It is particularly advantageous that an outer side of the holding element is arranged flush with the outside of the vacuum insulation element. Although the vacuum insulation element thus has a depression on this outer side, as a result of the quasi filling up of the depression with the retaining element over the entire surface, a flush overall surface is formed, which is thus virtually planar. In a particularly advantageous manner, an equal distance to the inside of the outer wall is therefore virtually given at each surface point of the vacuum insulation element. Precisely this situation can be avoided in the finished housing, in which the outer wall at the level of this vacuum insulation element undesirable dents or the like.

Preferably, the holding element is designed as a bracket holder and the vacuum insulation element clamped by the bracket holder. The holding element is preferably provided as a separate component to the vacuum insulation element and clamps or clamps the vacuum insulation element. A very specific connection between the holding element and the vacuum insulation element is achieved.

In particular, it is provided that the holding element completely surrounds the vacuum insulation element and, in this respect, surrounds in particular a band-like or strip-like manner. A particularly noteworthy attachment on the one hand and a vacuum insulation element as small as possible encompassing holding device is achieved.

It is preferably provided that the holding element on one of the inner wall facing the inside of the vacuum insulation element on the Inside is located and protrudes from the inside.

It is preferably provided that the intermediate space between the outer wall and the interior is filled with a foam material. This is advantageous in view of mechanical stability and position fixation of the vacuum insulation element in the gap. Especially in such a filling of this space with foam material occur in conventional cases, the above-mentioned deformations and in particular indentations on the outer wall of the housing. Due to the configuration of the housing according to the invention, it is thus possible, even when this intermediate space is at least partially filled with a foam material, not to lead to such unwanted deformations of the outer wall in the region of the retaining elements.

It is preferably provided that a thickness of the foam material between the inside of the outer wall and an outer side of the vacuum insulation element over the entire height and width and thus over the surface of the vacuum insulation element is the same. In this context, the entire surface of the vacuum insulation element is understood to mean that also the embedded retaining element on this outside of the vacuum insulation element contributes to the total area of the vacuum insulation element and is taken into account in this regard. Especially in the area of the holding elements, no foam material dilution thus occurs to the outer wall, so that here, too, no outer wall deformations occur during the foaming process of the foam material.

After the foaming process, it is known that the insulating foam used, which is for example a rigid polyurethane foam, shrinks. This shrinkage is greater in areas of greater foam thickness than in areas of smaller foam thickness. Thereby, the above-mentioned undesirable deformations occur, which then make themselves noticeable on the outer wall, by having corresponding dents, namely at the locations where a greater foam thickness prevails between the vacuum insulation element and the outer wall. The advantageous embodiment of the invention prevents exactly this.

It is preferably provided that the depression forms in the vacuum insulation element over the entire width of the vacuum insulation element.

It can be provided that a plurality of vacuum insulation elements is arranged in the intermediate space.

Furthermore, the invention relates to a household refrigerator with a housing according to the invention or an advantageous embodiment thereof.

In particular, it is provided that the inner wall of the housing represents the boundary wall for a receiving space for food in the interior of the household refrigerator and thus virtually forms the inner wall of the inner container.

The household refrigerator may be a refrigerator, a freezer or a combined food refrigerator and freezer.
