Description

The invention relates to a household appliance having a housing which has an electronic bag for receiving electronic components of the household appliance and a lid for covering the electronics bag.

It is known that household appliances, such as household refrigerators, have a housing in which a body, which is a cable pocket for receiving control devices and other electronic components, is arranged. This body is covered with a lid, which can also represent a front panel of the household appliance. In the context is from the DE 20 2008 005 353 U1 such a configuration known. There, it is provided that the cover with the body is non-destructively releasably connected, and to a locking device is formed. This is in the local configuration, in which the body and the lid are both made of the same material, namely plastic, advantageous.

Nevertheless, it is necessary in such a locking device to hold certain degrees of freedom of assembly. These tolerances lead to a gap formation between the body and the lid. Especially in household refrigerators, in which this body according to the above-mentioned prior art in a space between an inner container, which limits an interior for receiving the food, and an outer container in which thermally insulating material, in particular a foam, is introduced it come to the exit of this foam during the Einschäumvorgang. Since this is undesirable, it is necessary in known designs that in addition to a corresponding seal, for example, a foam strip between the body and the lid is mounted. After foaming, this foam strip must be removed again from covered mounting holes. As a result, the assembly cost is increased.

It is an object of the present invention to provide a household appliance, in which a component-reduced assembly of the electronic bag and the lid is made possible.

This object is achieved by a household appliance according to the features of claim 1.

An inventive household appliance comprises a housing which has an electronic bag for receiving electronic components of the household appliance and a lid for covering the electronic bag. An essential idea of the invention is to be seen in that the electronic bag and the lid are non-destructively connected non-destructively. Such a configuration allows a total module, which can be installed with exact position in terms of its original separate components after assembly. The electronics bag and the lid are fixed in position relative to each other. It is therefore no longer necessary to use additional assembly and sealing components in the production, which would then have to be removed later in a further assembly step.

It is preferably provided that the electronic bag and the lid are connected by a joining process. By such a joining relatively low-cost to produce connections can be created, which are still mechanically stable and reliable.

Particularly advantageous here is a compression.

In particular, it is provided that the electronic bag made of a first material and the lid are formed from a different second material. This embodiment allows a particularly needs-based design of the individual components relating to the electronics bag and the lid, so that the respective situation owed execution can be best taken into account. With regard to positional arrangement and specific stress then the very suitable material selection can be completed.

It is particularly advantageous that the lid of metal and the electronics bag are made of plastic. The electronic bag, which can also be made relatively complex in terms of their shape, can thus be produced very precise shape and yet inexpensive by a simple injection molding process. In addition, then also a very weight-reduced component is provided.

In contrast, a very stable component is provided by the metallic design of the lid, which retains its dimensional stability especially in a non-destructive unsolvable connection with the component concerning the electronic bag and maintains this dimensional stability even when connected quasi as a supporting effect. The entire module with the electronics bag and the lid is thus not undesirably deformed during manufacture.

Especially in such an embodiment, in which the lid of metal and the electronics bag are formed of plastic, it is advantageous that the lid at least one raised from a top wall extending and integrally formed with the top wall Having connecting part, which is pressed with the electronics bag. This results in respect of the basic production, as well as the permanently stable connections between these two materially different components significant advantages. It may be possible in the context that the metallic lid is inserted into a mold and the plastic material is entered into the tool, and in particular, it may also be in a certain warm and easily deformable state. The compound and in particular the pressing together, in which then the connecting part is pressed into the plastic, is then particularly smooth, without undesirable mechanical stresses when connecting and subsequent entire component achieved.

Regarding such a procedure may be on the WO 03/031095 be referenced, the disclosure content for the production of a composite component of a metallic component with such a connecting part and a plastic component for the present invention is disclosed as fully and therefore to be regarded as included in the disclosure.

It is preferably provided that the connecting part is designed as a pipe socket-like punched edge. This shape-specific design of the connecting part allows a particularly extensive abutment between this connecting part and the plastic, so that the compression and then achievable thereby permanently reliable and fixed position connection between the electronic bag and the lid is increased again.

Preferably, it is provided that the punching edge has at its outer end at least a portion of the outer circumferential bead on a lateral wall, in particular has a bead tapering to the free end. The joining and pressing of the connecting part in the plastic is thereby facilitated and the complete surrounding of the connecting part on the outside and the inside through the plastic is favored. By rejuvenation a kind of entanglement or anchoring is formed, whereby the position assurance is improved in the direction of the tube axis of the punching edge.

It is preferably provided that the connection part extends completely into the electronics pocket and the electronics pocket rests on an inner side of the cover wall on which the connection part is formed. The above-mentioned advantages are thereby further improved and a snug fit of the plastic part to the lid is achieved.

It is preferably provided that the electronics pocket has a seal on a side resting against a cover wall of the cover, in particular on an edge of the side, which bears against the cover wall. Such a specified position of a seal favors the medium-tight connection between the lid and the electronics bag.

It is preferably provided that the seal is a sealing lip with a cross-section tapering to a free end shape. As a result, a relatively filigree design of the seal is achieved, which is relatively flexible in the deformation at its free front end, so that they can invest reliably even with complex geometries of the inside of the top wall and seals accordingly.

It is preferably provided that the seal is molded onto the electronics bag. As a result, the manufacturing and assembly costs are reduced and achieved a permanently positionally secure arrangement of the seal on the electronics bag.

It is preferably provided that the seal is formed integrally with the electronic bag and is made of the same material as the electronic bag.

However, it can also be provided that the electronic bag is formed with the seal as a 2K component, and thus the plastic material of the electronic bag is different from the plastic material of the seal.

Due to the injection-molded design of the seal on the electronics bag, a reliable maintenance of the relative positions between the seal and the electronics pocket when pressing the electronics bag with the lid is achieved.

Advantageously, the seal is applied to a flat surface portion of the top wall. As a result, the top wall is formed little complex shape and relatively easy to manufacture and the seal can invest with appropriate freedom of deformation of the top wall and thereby achieve a preferred sealing effect.

It can also be provided that the cover wall has a recess in a surface section into which the seal extends, in particular can be fitted precisely in position. Thus, the seal is arranged quasi at least partially engaging in the top wall, so that a certain toothing is realized. On the one hand, this embodiment achieves a complete contact of the electronic bag with the top wall, so that here a possible large-scale mechanical contact between the electronic bag and the lid is formed. Through this depression or groove, the sealing effect and the positionally precise arrangement of the free end of the seal is achieved. An undesired deformation or positional change of the seal in the manufacturing process of the module consisting of the lid and the electronics bag and an optionally resulting inadequate sealing is prevented.

In a particularly advantageous manner, the household appliance is designed as a household refrigerator. This household refrigerator is designed so that the housing has an inner container that defines an interior space. This inner container is preferably formed of plastic and limited with its walls this interior, in the food for preserving and storing, such as food and drinks, can be introduced. This inner container is surrounded by an outer container, which may for example be made of metal, in particular of sheet metal. In a space between the inner container and the outer container, a thermally insulating material is at least partially introduced. In particular, at least partially, a thermally insulating foam can be introduced here. The module with the electronics pocket and the lid extends at least partially into this gap, wherein in particular the electronic bag can also be partially surrounded by the thermally insulating material, in particular can be foamed. Due to the design of the electronic bag and the lid, it is precisely in such a design of a household appliance prevents that when introducing the foam material this undesirably exits through joints between the lid and the electronics bag.

The lid may preferably also be arranged as a front panel of the household appliance, but may also be covered by a further component, in particular an additional panel, the front.

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.
