It is the object of the present invention to create a household appliance and a method in which such a locally specified electronic module is improved with regard to the mechanical as well as the electrical requirements. This object is achieved by a domestic appliance and a method according to the independent claims.

The invention relates to a household appliance with a housing and a machine compartment which is formed in a lower area of the housing viewed in the height direction of the household appliance and in a rear area of the housing viewed in the depth direction of the household appliance. This machine room is laterally delimited by side walls. The household appliance also has an electronic module, which in Machine room is arranged. The electronics module is arranged on a side wall that delimits the machine room. A grounding contact is arranged on a housing of the electronic module. This can be used to ground the electronic module or set it to ground potential. Provision is made for this grounding contact to be electrically conductively and mechanically connected to an electrically conductive partial element of the side wall, namely connected in a specific manner, namely clamped. Such a configuration means that the electronics module can be arranged in a specific location in the machine room and, in this connection, better takes into account both electrical requirements and mechanically stable positioning. The grounding contact and the connection to the electrically conductive sub-element simultaneously create a mechanical connection which not only represents abutting against one another, but is also provided with a defined application of force in this respect. This creates the clamping connection. In addition, it is provided for this mechanical clamping connection that precisely the components that then also interact electrically are used. This also enables safe grounding of the electronics module. This is also preferably because the grounding contact is directly connected to the electrically conductive sub-element by the mechanically clamping connection with the application of force. This also ensures safe grounding.

In one exemplary embodiment, it is provided that the grounding contact is designed as a contact tongue oriented in the width direction of the household appliance. In particular, the contact tongue has a length oriented in the width direction which is many times greater than a width and/or thickness of the contact tongue oriented perpendicularly to the width direction. In this way, in particular, a plate part or a flat part is provided, which can work particularly advantageously with the electrically conductive partial element with regard to assembly. During assembly, the clamping effect can thus be built up very continuously. In addition, a particularly reliable and stable electrical contact is then also made possible with the electrically conductive partial element and the grounding contact.

Such a configuration and arrangement of the grounding contact is also preferably associated with a certain deformation elasticity, so that this contact tongue can pivot elastically about a vertical axis. With that you can Mount in a particularly advantageous manner, the mechanical clamping connection are established. In particular, this mechanically clamping connection is also maintained when the electronic module is arranged in the installed end position in the machine room.

The electrically conductive partial element of the side wall is preferably arranged in a freely cantilevered manner in the width direction of the domestic appliance. In particular, this electrically conductive sub-element can be strip-like or plate-like and thus also preferably represents a flat element. With this configuration, the grounding contact and the electrically conductive sub-element are advantageously oriented with their flat extension planes essentially parallel to one another. A large-area contact between the grounding contact and the electrically conductive element is achieved. This provides two specific geometric elements with specific orientations to one another, which advantageously enables and then maintains the creation of the grounding connection on the one hand and the mechanically clamping connection on the other hand.

In particular, it is provided that in the clamped state between the grounding contact and the electrically conductive partial element, a front edge of the partial element is pressed against a side surface of the grounding contact.

In one exemplary embodiment, in the clamped state, the electrically conductive partial element is pressed into a gap in a rear-side coupling device of the housing and is clamped therein. The coupling device has the grounding contact. The gap is open in the width direction. As a result, the grounding contact dips sideways into the gap. This arrangement achieves a particularly secure and stable clamping mounting of the grounding contact. In particular, this is accommodated in a pocket which represents the gap.

According to the invention, the clamping connection creates a pre-fixing position of the electronic module on the side wall before final assembly of the electronic module on this side wall. It is thus achieved in a particularly advantageous manner that an additional fastening option for the electronic module can be created in the end position. Through the in the Connection already formed Vorfixierposition it is possible in particular that the electronic module for final assembly then no longer has to be held by the fitter. In particular, the pre-fixing position is a self-retaining position. The mounting of further fastening devices is then very advantageously possible.

Provision is preferably made for the housing of the electronics module to have a niche. The ground contact is located in this niche. As a result, the ground contact is protected to a certain extent. In particular, the niche is open when viewed in the width direction of the household appliance. This means that the electrically conductive sub-element can engage during assembly. In particular, the niche is formed by the above-mentioned gap or can have the gap and be larger than the gap. In one embodiment, the gap does not exist in the niche. The rear part, in particular the electrically conductive partial element integrated therein, is then only arranged in a clamping manner on the rear wall.

In one exemplary embodiment, the niche is delimited by a rear wall, the rear wall being coupled to a rear part of the side wall when the electronic module is in the final assembled state on the side wall. In particular, a clamping and overlapping arrangement is provided here between the rear wall and the rear part. This further supports the mechanically stable positioning of the electronic module on the side wall. In particular, as a result, the pre-fixing position that is advantageously created is also maintained in an improved manner. The rear wall and the rear part are in particular plate-shaped elements. They are oriented with their two-dimensional extension in the width direction and in the height direction or stretched in this plane. With such a design, the connection between the grounding contact and the electrically conductive part is then covered on the front in the final assembled state. In this respect, a double wall is formed as a cover and protection for the grounding contact and the electrically conductive partial element by the rear wall and the arrangement of the rear part directly adjacent and coupled thereto.

According to the invention, the housing of the electronics module, in particular a rear wall of the housing, is connected to a rear part of the side wall with a screw connection. This screw connection is particularly advantageous after the production of the formed pre-fixing position. This screw connection improves the mechanically stable mounting of the electronic module on the side wall. In addition, the installation of the screw connection at this specific point is advantageous, since the overlapping arrangement between the rear wall and the rear part is additionally screwed.

In particular, the rear wall has a through hole for a screw. In particular, this is also intended for the rear part. The side wall preferably has a screw boss with a thread into which the screw can be screwed. In particular, the rear wall represents a front boundary wall of the above-mentioned advantageously existing niche. This rear wall is thus used in a multifunctional manner.

In one embodiment, the gap does not exist in the niche. The rear part, in particular the electrically conductive partial element integrated therein, is then only arranged in a clamping manner on the rear wall.

In particular, it is provided that the screw connection is formed in the area of the clamping connection between the grounding contact and the electrically conductive partial element. In this way, the mechanically stable mount is locally concentrated in the front area of the electronic module and formed by several different connections. A particularly stable positioning of the electronics module in this rear area is made possible.

In particular, it is provided that the housing of the electronics module is connected to the side wall by a pivot bearing on a side opposite the clamping connection. In particular, this opposite side is viewed in the depth direction. In particular, this opposite side thus represents a rear side. A particularly simple and assembly-friendly attachment can be made possible by this pivot bearing. First of all, the electronics module or its housing can be coupled in the area of the pivot bearing. For this purpose, pivots of this pivot connection, which are arranged on the housing of the electronic module, can be coupled with counter-pivoting elements, which are arranged on the side wall, and the pivot bearing can thus be formed become. Subsequently, the electronic module can then be pivoted from this starting position about the pivot bearing and thus pivoted in an intermediate assembly position towards the side wall and arranged there. During this pivoting movement, the coupling between the grounding contact and the electrically conductive element can then take place automatically and, with further pivoting, the clamping connection can then be established in this regard. The pre-fixing position is then reached and pivoting is completed. Subsequently, only the above-mentioned advantageous screw connection is then provided in this rear area of the housing of the electronic module. The swivel bearing thus forms, on the one hand, a rear mechanical mount for the housing of the electronics module on the side wall and also provides a particularly advantageous handle during assembly and, in this regard, changing the position of the electronics module.

In an advantageous embodiment, the housing of the electronics module has support ribs on an underside, viewed in the vertical direction. With these support ribs, the housing rests on a support on the side wall. As a result, fixing the position in the height direction is additionally supported. In particular, these support ribs also create a guide so that when the electronic module is brought into the engine room, in particular in order to initially form the above-mentioned advantageous embodiment with the pivot bearing, the electronic module can be pushed in in a targeted manner. In this way, the pivot bearing elements can be coupled to the counter-pivot bearing elements in a very easy-to-assemble manner.

The housing of the electronics module preferably has a barrier wall to prevent contact between a wiring harness and a boundary wall of the machine room made of an electrically conductive material. A wiring harness in this regard relates to one or more electrical lines or cables. This barrier wall thus advantageously avoids direct contacting between the wiring harness and the electrically conductive boundary wall. In this regard, undesired electrical contacts and functional impairments of the household appliance resulting therefrom can thus be reliably avoided.

The invention also relates to a method for mounting an electronics module on a side wall that delimits a machine room of a household appliance. The electronics module is positioned in the machine room. A housing of the electronics module is coupled to this side wall, so that an intermediate assembly position or an intermediate assembly position is thereby created. In this intermediate assembly position, there is in particular no grounding contact between the electronic module and an electrically conductive partial element of the side wall, i.e. there is no electrically conductive connection between these elements in the intermediate assembly position. The electronic module is moved along an assembly path starting from the intermediate assembly position to an end position, with a grounding contact of the electronic module being electrically conductively and mechanically clamped connected to an electrically conductive partial element of the side wall on this assembly path. The intermediate assembly position is in particular the one in which an advantageously existing swivel bearing is formed between the electronics module and the side wall. This means that in this respect the pivoting elements are coupled to the counter-pivoting elements in the intermediate assembly position. Starting from this intermediate assembly position, the electronic module is then pivoted about the pivot bearing toward the side wall. In particular, the front side of the electronics module viewed in the depth direction is pivoted towards the side wall. In this context, the assembly path relates in particular to the path between this intermediate assembly position and the position at which pivoting is complete.

Preferably, the housing of the electronics module is pivoted in this assembly path and the clamping connection between the grounding contact and the electrically conductive sub-element is automatically achieved during this pivoting.

According to the invention, a self-retaining pre-fixing position of the electronic module on the side wall is generated by the clamping connection before the final assembly of the electronic module on this side wall. According to the invention, an additional screw connection is produced between the housing of the electronic module and the side wall during assembly after this self-retaining pre-fixing position has been reached. In particular, this screw connection is produced in the area of the mentioned clamping connection between the grounding contact and the electrically conductive partial element. "Top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction" etc. are the positions specified for the intended use and intended arrangement of the device and directions given.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

In 1 a household appliance 1 is shown in a schematic representation, which is a household refrigeration appliance here. The household refrigeration appliance is designed for storing and preserving food. In particular, it can be a refrigerator or a freezer or a combination fridge-freezer. The household appliance 1 has a housing 2 . At least one receiving space 3 for food is formed in the housing 2 . The household appliance 1 also has a door 4 which is arranged on the housing 2 such that it can pivot.

Viewed in the vertical direction (y-direction), the household appliance 1 has a machine room 6 in a lower region 5 . This machine room 6 is formed in a rear area 7 in the depth direction (z-direction) of the household appliance 1 . In the configuration of the household appliance 1 as a household refrigeration appliance, components of a refrigeration cycle are arranged in this machine room 6 . In particular, a compressor is arranged in this machine room 6, for example.

In the width direction (x-direction), this machine room 6 is laterally delimited by side walls.

In 2 the household appliance 1 is shown on the back. The partial illustration shows the machine room 6, which is laterally delimited by the side wall 8 shown. For the sake of clarity, further components in the machine room 6 are not shown. An electronic module 9 of the household appliance 1 is arranged in this machine room 6 on an inner side 8a of this side wall 8 . The electronics module 9 has a housing 10 . This is designed in particular as a cuboid. In particular, it is arranged completely within the machine room 6 . The machine room 6 is delimited by a front wall 11 viewed in the depth direction. This front wall 11 is in particular made of an electrically conductive material.

In addition, the machine room 6 is delimited at the top by a ceiling wall 12 . In particular, the machine room 6 is open to the rear.

In 4 the electronics module 9 with the housing 10 is shown in a perspective view. Pivoting elements 14 are formed on a front side 13 of the housing 10, which faces the front wall 11 in the assembled state of the housing 10 in the machine room 6. The pivoting elements 14 are formed in one piece with the housing 10 . Viewed in the depth direction, a coupling device 16 is formed on a rear side 15 of the housing 10 opposite the front side 13 . The coupling device 16 is connected to the housing 10 in one piece. The housing 10 is in particular made of plastic.

The coupling device 16 is intended to be coupled to the side wall 8 at least mechanically. In particular, the side wall 8 has a coupling flange that in particular a rear part 17 ( 2 ) on. This coupling flange is formed as a vertical plate strip, which extends in the plane that is spanned by the height direction and the width direction.

In 3 is shown in a perspective view of the partial area of the side wall 8 on which the electronic module 9 is arranged. In 3 this electronics module 9 is not shown for the sake of clarity.

The side wall 8 has a receiving niche 18 . The housing 10 extends into this in the mounted end position.

As can be seen, a formation of counter-pivoting elements 20 is provided on a front side viewed in the depth direction, in particular a front boundary wall 19 of this receiving niche 18 . The pivoting elements 14 engage in these counter-pivoting elements 20 . In the coupled state between these elements 14 and 20, a pivot bearing 21 ( 7 and 8 ) educated. The housing 10 can be pivoted about this pivot bearing 21 during assembly.

In addition, in 3 a pad 22 is formed. The support 22 is in particular a lower boundary wall of the receiving niche 18. It can also be seen that a screw dome 23 is formed in a rear region of the side wall.

The rear part 17 of the side wall 8 extends as a vertical plate strip. It is spanned in the x-y plane. This rear part is made of an electrically conductive material. Especially from sheet metal.

As moreover in 2 and 4 As can be seen, the housing 10 has a grounding contact 24 in this coupling area or in the coupling device 16 . As a result, the electronics module 9 is grounded when it is connected to a corresponding potential. Provision can be made for this grounding contact 24 to be arranged in a rear wall 25 of this coupling device 16 . The ground contact 24 may be included in this backplane 25 in this context. However, provision can also be made for the grounding contact 24 to be arranged separately and at a distance from this rear wall 25, in particular further to the front when viewed in the depth direction offset to this rear wall 25 is arranged. In the embodiment in which the grounding contact 24 is arranged in the rear wall 25, the rear wall 25 also serves as a support for this grounding contact 24. It can be provided that the grounding contact 24 is covered to the rear by the rear wall 25. However, it is also possible for the grounding contact 24 to be exposed to the rear.

This coupling device 16, in particular the rear wall 25, forms an area in front of it, in particular a niche 26.

When assembled as shown in 2 As can be seen, the rear part 17 is arranged so that it overlaps with this rear wall 15 in the width direction. In this regard, the rear wall 25 is oriented further to the rear and thus covers a partial area of this rear part 17 . Provision is made in particular for this rear wall 25 to bear directly against the rear part 17 in the assembled state. In particular, a mechanically clamping connection can be formed here.

Furthermore, in 4 it can also be seen that the housing 10 has support ribs 27 . These support ribs 27 are arranged on an underside 28 of the housing 10 and protrude downwards.

When mounting the electronic module 9 on the side wall 8, as is the case below with reference to Figures 5 to 12 is explained, first this housing 10 is provided. It is then positioned relative to the side wall 8 in such a way that the support ribs 27 are seated on the support 22 . According to the arrow P1, as in figure 5 is shown, the housing 10 and thus the entire electronic module 9 pushed forward. The support ribs 27 serve as a guide. In 6 then a pushed-forward position of the electronics module 9 is shown, in which the pivoting elements 14 are not yet coupled to the counter-pivoting elements 20 . If you push further forward, according to the illustration in 7 an intermediate assembly position or an intermediate assembly position is reached, in which the pivot bearing 21 already explained is formed. In this regard, the pivoting elements 14 and the counter-pivoting elements 20 are coupled to one another. In this context, according to the horizontal sectional view 8 , which is a view in the xz plane, this intermediate mounting position of the electronics module 9 is shown. It can be seen that the front area of the electronic module 9 is already in direct contact with the side wall 8, in particular in the receiving niche 18. The rear area of the electronics module 9 is inclined in this respect and is still at a distance from this rear wall 8 in the width direction. As in FIG 8 can be seen, an additional web 29 is formed in this niche 26 behind the rear wall 25 in an advantageous embodiment. The web 29 is formed at a distance from the front wall 25 . As a result, a gap 30 is formed between the rear wall 25 and this web 29 .

If now, starting from this intermediate assembly position, the electronic module 9 is rotated around the pivot bearing 21, which is 8 has a pivot axis perpendicular to the plane of the figure, is pivoted towards the side wall 8 in the direction of the arrow P2, this assembly method results in mechanical contact between the front side of the rear wall 25 and the back side of a partial element 17a of the rear part 17. This partial element 17a represents an electrically conductive Sub-element 17a of the side wall 8. This electrically conductive sub-element 17a extends in a cantilevered manner in the width direction towards the electronic module 9. In this regard, on the other hand, the rear wall 25 freely cantilevers in the width direction toward the side wall 8 .

If the web 29 is present and the sub-element 17a is inserted into it, it is in particular in contact with the web 29 and the rear wall 25 on both sides. It can be like this in 10 and 12 as a further example, the web 29 may not be present and thus the gap 30 may not be present. Then only the niche 26 is formed. The partial element 17a is then only arranged directly with the rear wall 25 in a clamping manner.

With this pivoting according to the arrow P2, a further intermediate assembly position is reached, as is then shown in 9 can be seen. In 9 the pivoting is completed in this regard. In 9 a pre-fixing position of the electronics module 9 on the rear wall 8 is advantageously achieved. As in the horizontal sectional view in 10 as can be seen, the rear wall 25 is in direct mechanical contact with the rear part 17 and is also arranged in a clamping manner in this respect. In particular, it is provided that the grounding contact 24 is brought into direct contact with the electrically conductive sub-element 17a and, in this regard, is also directly connected to the electrically conductive sub-element 17a in a mechanically clamping manner.

As a result, both the grounding contact 24 is connected to ground potential and, on the other hand, a mechanically stable connection is also created at the point.

Due to this clamping connection at this point with the rear pivot bearing 21, as shown in 8 and 10 a self-retaining pre-fixing position of the electronic module 9 on the side wall 8 is reached. As in 10 As can be seen, the housing 10 is immersed in the receiving niche 18 in some areas, in particular approximately halfway.

In addition, the electrically conductive partial element 17a is preferably inserted into the gap 30 . This further improves the mechanically holding connection. Furthermore, it can be seen that a feed-through hole 35 on the rear wall 25, which is designed for the passage of a screw, is arranged flush with the screw dome 23.

A further boundary wall 31 of the coupling device 16 is preferably in direct contact, viewed in the width direction, and thus in abutment with a stop web 32 of the side wall 8. This configuration means that the latter is in accordance with FIG 9 and 10 achieved intermediate assembly position can be reached more precisely. An aligned arrangement between the through hole 35 and the screw dome 23 is thus automatically achieved. In addition, the desired overlap in the width direction between the rear wall 25, in particular also the grounding contact 24, and the electrically conductive partial element 17a is also achieved by this stop arrangement.

In a subsequent further assembly step, as shown in 11 a screw 33 passed through the through-hole 35 and screwed into the screw boss 23 . As a result, a further mechanical connection is created by this additional screw connection. this is in 11 shown where in 12 again a schematic horizontal sectional view at the location of the screw 33 is shown. The screwed state in this regard can be seen. It can be provided that the electrically conductive sub-element 17a is thickened at its edge facing the gap 30 . As a result, the mechanically clamping connection with the grounding contact 24, in particular also the rear wall 25, in particular the gap 30, can be improved.

In particular, it is provided that the electronic module 9, in particular the housing 10, has a barrier wall 34 ( 4 ) having. This barrier wall 34 is provided in particular to avoid contact between a wiring harness (not shown) and the boundary wall 11 and/or the boundary wall 12 . The electronic module 9 can be mounted on the left-hand side wall 8 when viewed from the rear of the housing 2 or else on an opposite right-hand side wall (not shown) of the machine room 6 .

Since the electronic module 9 is assembled last during the assembly process, it can also be provided that an intermediate line set, which relates to electrical lines between a compressor and the electronics housing 9, can be formed to a minimum in terms of length. This in turn ensures that this set of intermediate lines does not touch the compressor due to approval requirements. So that an equipment wiring harness does not touch the boundary wall 11 and/or the boundary wall 12 , the barrier wall 34 already mentioned is formed on the housing 10 of the electronic module 9 .

The configuration provided is also particularly advantageous in that no additional grounding screw is required to establish a grounding connection.

This saves at least one assembly step and an additional component, namely the grounding screw, is no longer required. In particular, this also eliminates the need for spring washers and washers, which are provided when a grounding screw is used in this way.
