Description

The invention relates to a domestic refrigerator with an at least partially flat device component, which has a flat component area.

Domestic refrigerators, such as a refrigerator or a freezer or a combined refrigerated freezer, usually have a housing on which a door is pivotally mounted. In the housing a receiving space for food is formed, in which they can be stored and preserved.

Outer container of this housing are usually formed of sheet metal parts, which are thus also flat device components. In order to achieve a corresponding mechanical stability in such relatively large flat components, they are to be formed with a specific thickness. This requires a corresponding cost of materials and thus increases the weight.

It is an object of the present invention to provide a household refrigeration appliance, which is formed with respect to flat device components weight-saving and yet has sufficient stability.

This object is achieved by a household refrigerator, which has the features of claim 1.

An inventive household refrigeration device comprises at least one device component, which is formed at least partially flat. The device component has a flat and thus in particular flat component area. An essential idea of the invention can be seen in that the planar component area has a first area of the area which is structured and has a second area of the area which is unstructured. By such a configuration and thus by a partial structuring, a mechanical stabilization is achieved, and thus the material thickness can be reduced at least in this structured surface portion. This leads to weight savings the device component while still maintaining at least mechanical stability. Moreover, according to the invention, not the entire device component is structured in the areal component area, but a second area subarea that is to be characterized as an unstructured area compared to the first area subarea can in particular be provided with further components, for example, on this second area of the area, which is smooth compared to the first area area a film or the like, carried out without a structuring would be in this film and thus then also on the visible side of the film. As a result, this corresponding smooth surface of the second surface part region also remains so designed that the attachment of further elements and components is possible in a simple and large-area manner and these are then also held permanently thereon.

The invention thus provides a material component reduced device component which is nevertheless highly stable, on the other hand, in addition, the multi-functionality allows that in the non-structured second surface portion a mechanically stable application of other components is possible.

It is preferably provided that the first surface portion is structured over its entire dimensions. The stability at least in this area sub-area is thereby increased.

It is preferably provided that the first surface part region is structured by a surface embossing. This is a particularly advantageous embodiment, since the structuring locally very targeted and then formed permanently secure position. In addition, such a surface embossing also allows a targeted patterning with regard to the desired structuring.

By embossing also a very specific deformation of the first surface part area is performed, so that the structuring can also be generated very individual and needs-based.

It is preferably provided that the structuring is produced by a rolled-in surface embossing. The advantages mentioned above are thereby again favored. In addition, a simple and stable tool can be provided by this embodiment, which is formed in particular from two opposing sides of the device component attacking rollers, one of these two rollers is designed on its roll shell side so that the desired structuring as a surface embossing when passing the device component is generated between two rollers in the first surface portion.

It is preferably provided that the structuring is designed as nonuniform patterning with respect to its orientation and dimensions of structural elements. As a result, a particularly extensive reduction of the material thickness of the device component can be produced and still a very high mechanical stability can be maintained.

It is preferably provided that the component region has a front side and a rear side as surfaces, and only the back side has a first structured surface part region. This is particularly advantageous in that a device component can also be arranged and installed on the household appliance in such a way that it can be partially viewed by a user, at least in the erected state or in the used state. Since a structured surface may possibly also influence the visual impression of the household refrigerating appliance, the covert formation of the structuring and thus the possibility of arranging the appliance component such that the structured area subarea is arranged in the non-visible with conventional installation and use of the household refrigerating appliance is an advantage. As a result, the structuring can not be damaged and, moreover, a high-quality impression of the domestic refrigerator remains.

It is preferably provided that the second surface portion is formed as a strip. A straight-line gluing or printing is very easy.

It is preferably provided that the device component is a housing wall of a housing of the household refrigerator.

Preferably, it is provided that the device component is arranged in the domestic refrigeration appliance such that the second area of the area forms a visible surface and the first one Surface area forms a non-visible surface of the household refrigerator. It can also be provided that the device component is part of a door or a cover. The device component can also be, for example, a mounting rail or a backing part or a handle or a hinge.

As a result of the invention, material savings and nevertheless high mechanical stability are achieved by an embossed structure in the case of an individual component which is a device component, and thus structuring is achieved while maintaining existing, functional requirements.

Especially when the device component is installed at a position of the household refrigerating appliance in which sealing requirements occur, the above-mentioned advantageous embodiments concerning a structured surface portion and an unstructured surface portion are advantageous. Because in this context, the unstructured second surface portion may then be arranged directly adjacent to each other for sealing effect in contact with another device component and a sufficient sealing effect generated by the smooth unstructured surface, which may not be achieved in the structured surface portion. In particular, therefore, no drops of water or other liquids can penetrate and freeze in such a sealing area, so that a freeze-together of the device component according to the invention with another component of the household refrigerating appliance is avoided.

Moreover, even the aspect with the second unstructured area portion also offers the portion by which an adhesion force of an adhesive tape is not affected if such an item is to be attached to the component of the apparatus.

In addition, even smaller forces during forming occur, and punches are easier to handle tools. The structuring can moreover be designed so that winding or stacking of the device component is made possible.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively specified combination but also in other combinations or in isolation, without the frame to leave the invention. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained.

Embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is shown in a simplified schematic representation of a household refrigerator 1, which has a housing 2, on which a door 3 is pivotally mounted. The housing 2 comprises a receiving space 4, are introduced into the food. The domestic refrigeration appliance 1 comprises a plurality of planar appliance components which each have at least one flat component area. exemplary can be mentioned as a device component 5 is a flat housing wall, which also has a plurality of flat and in particular flat component areas. The device component 5 is preferably formed as a sheet and is at least partially formed and structured there for weight reduction while still sufficient and in particular the same mechanical stability with a smaller thickness. The device component 5 therefore comprises at least a first surface portion which is structured and a second surface portion which is unstructured by comparison.

Exemplary is in to Fig. 2 a device component 5 is shown, which may be said housing wall or, however, may also be, for example, a wall portion of the door 3. However, the device component 5 can also be, for example, another cover or a mounting rail or a backing part or the like.

In Fig. 2 an intermediate production state of the device component 5 is shown in which it is still completely designed as a flat plate. The device component 5 in this context comprises a planar component region 6, which has a first surface portion 7, which is structured and thus has a defined specific surface roughness by a pattern. In addition, the component region 6 comprises a second surface portion 8, which is unstructured compared to the first surface portion 7 and thus is smoother. This also means in particular that the surface roughness of the first surface portion 7 is greater than the second surface portion 8. In addition, it is provided that a further first surface portion 9 is formed, which is also structured and which on the opposite side to the aforementioned first surface portion 7 of the second surface portion 8 is formed. Due to this specific formation of structured and unstructured areas, the plates provided and stored for further processing can be simply stacked since the outer areas have a practically identical height (due to structuring) and thus the plates do not rest on one another. It can also be a simple training as so-called coilware and thus the easier winding done.

As can be seen, the second surface portion 8 is formed as a strip, in particular as a straight strip. It is also provided in particular that the device component 5 has the corresponding structuring only on a rear side 5a, but this is not provided on a front side 5b. The front side 5b is in the installed state of the device component 5 in the household refrigerator 1 is a visible surface, whereas the back 5a forms a non-visible surface and is therefore covered.

A structuring 7a in the first surface part region 7 is a rolled surface embossing which also applies to a structuring 9a of the further first surface part region 9. The patterns 7a and 9a are formed as nonuniform patterns with respect to the orientation and dimensions of features.

This is in Fig. 3 an enlarged view of a portion of the structuring 7a shown. The structural elements are in length and / or width and / or height and / or extent differently shaped elevations. Due to its smoothness, the second area of the area 8 can then be provided with a film over its full area, or else other printing or varnishing can be provided.

In Fig. 4 is then a converted final state of the device component 5 as shown in FIG Fig. 2 shown. It can be seen that the deformations have taken place in the region of the second surface portion 8 and in this respect a relatively complex designed component is produced. It can also be seen that as a result of this deformation, the structuring 9a is arranged as no longer visible and is concealed on the visible side by partial regions of the second surface portion 8. On the other hand, as the visible surface, that portion of the front side 5b is formed which is formed by the smooth surface of the unstructured second surface portion 8.

Both the number and the shape of the respective sections 7 to 9, as well as the shape of the exemplary device component 5 according to Fig. 4 , are to be understood as exemplary only, and there are also a variety of other embodiments of device components 5 with various other configurations with respect to Number and size of the respective first and second surface portions considered to be included.
