Definitions
- One aspect of the invention relates to a household appliance with a housing.
- the household appliance also has a machine room which is formed in a lower and rear area of the housing.
- components of the refrigeration circuit of the household appliance are arranged in the machine room.
- the machine room is laterally delimited by a side wall of the housing.
- the household appliance also has an electronics module which is arranged in the machine room on the side wall.
- Another aspect of the invention relates to a method for mounting an electronic module on a side wall that delimits a machine room of the household appliance.
- Such household appliances and assembly methods are from the EP 2 492 619 A1 and the DE 10 2012 212 401 A1 known.
- Such a specific positioning of an electronic module in the machine room enables on the one hand a space-saving attachment and on the other hand an advantageous accessibility even after the assembled state.
- the object of the present invention is 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.
- One aspect of the invention relates to a domestic appliance with a housing and a machine room which is formed in a lower area of the housing viewed in the height direction of the domestic appliance and a rear area of the housing viewed in the depth direction of the domestic appliance.
- This machine room is laterally limited by side walls.
- the household appliance also has an electronics module, which in the Machine room is arranged.
- the electronics module is arranged on a side wall that delimits the machine room.
- a ground contact is arranged on a housing of the electronics module. By means of this, the electronics module can be grounded or put on ground potential.
- this ground contact is electrically conductively and mechanically connected to an electrically conductive sub-element of the side wall, namely is connected in a specific manner, namely is connected in a clamping manner.
- the grounding contact and the connection to the electrically conductive sub-element thus simultaneously create a mechanical connection that not only makes contact with one another, but is also provided with a defined application of force in this regard. This creates the clamping connection.
- this mechanical clamping connection that 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 through the mechanically clamping connection. Safe earthing is thus also achieved.
- the grounding contact is designed as a contact tongue oriented in the width direction of the household appliance.
- 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 perpendicular to the width direction.
- a plate part or a flat part is provided which can act particularly advantageously with the electrically conductive sub-element with regard to assembly. During assembly, the clamping effect can therefore be built up very continuously.
- a particularly reliable and stable electrical contact is then also made possible with the electrically conductive sub-element and the grounding contact.
- Such a configuration and arrangement of the ground and contact is also preferably accompanied by a certain elasticity of deformation, so that this contact tongue can pivot elastically about a vertical axis.
- the The mechanically clamping connection can be built up in a particularly advantageous manner. In particular, this mechanically clamping connection is still maintained when the electronics module is arranged in the assembled end position in the machine room.
- the electrically conductive sub-element of the side wall is preferably arranged so as to be cantilevered in the width direction of the household appliance.
- this electrically conductive sub-element can be strip-like or plate-like and thus also preferably represents a flat element.
- This configuration advantageously means that the grounding contact and the electrically conductive sub-element are oriented essentially parallel to one another with their planar extension planes. A large-area contact between the grounding contact and the electrically conductive element is achieved. Two specific geometric elements with specific orientations with respect to one another are thus provided, which advantageously enable and then maintain the creation of the grounding connection on the one hand and the mechanically clamping connection on the other hand.
- the electrically conductive sub-element in the clamping state, is pressed into a gap in a rear coupling device of the housing and is held therein in a clamping manner.
- the coupling device has the ground contact.
- the gap is open in the width direction.
- the earthing contact dips laterally into the gap.
- the clamping connection creates a pre-fixing position of the electronic module on the side wall before the final assembly of the electronic module on this side wall.
- an additional fastening option for the electronic module can be created in the end position.
- the housing of the electronics module has a niche.
- the earthing contact is located in this niche.
- the earthing contact is arranged in a protected manner to a certain extent.
- the niche is open when viewed in the width direction of the household appliance.
- the electrically conductive sub-element can intervene during assembly.
- the niche is formed in particular 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 sub-element integrated therein, is then only arranged in a clamping manner on the rear wall.
- the niche is delimited by a rear wall, the rear wall being coupled to a rear part of the side wall in the final assembled state of the electronic module on the side wall.
- 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 electronics module on the side wall.
- the advantageously generated pre-fixing position is also kept improved in this way.
- the rear wall and the rear part are in particular plate-shaped elements. With their two-dimensional extension, they are oriented in the width direction and in the height direction or are spanned in this plane. Such a configuration then covers the connection between the grounding contact and the electrically conductive part on the front side in the finally assembled state.
- a double wall as a cover and protection for the grounding contact and the electrically conductive sub-element is formed by the rear wall and the arrangement of the rear part directly adjacent and coupled to it.
- 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 in the aftermath of the generation of the trained Vorfixierposition formed.
- This screw connection improves the mechanically stable mounting of the electronics module on the side wall.
- it is precisely the construction of the screw connection at this specific point that is advantageous, since the overlapping arrangement between the rear wall and the rear part is additionally screwed.
- the rear wall has a through hole for a screw. In particular, this is also provided for the rear part.
- the side wall preferably has a screw dome with a thread into which the screw can be screwed.
- the rear wall represents a front-side delimiting wall of the above-mentioned advantageously existing niche. This rear wall is thus used multifunctionally.
- the gap does not exist in the niche.
- the screw connection is formed in the area of the clamping connection between the grounding contact and the electrically conductive sub-element.
- the mechanically stable mounting is locally concentrated in the front area of the electronics module through several different connections. This enables the electronics module to be positioned in a particularly stable manner in this rear area.
- the housing of the electronics module is connected to the side wall with a pivot bearing on a side opposite the clamping connection.
- this opposite side is viewed in the depth direction.
- this opposite side thus represents a rear side.
- This pivot bearing enables particularly simple and easy-to-assemble attachment. This is because the electronics module or its housing can first be coupled in the area of the pivot bearing.
- swivels of this swivel connection which are arranged on the housing of the electronics module, can be coupled with counter-swivel elements which are arranged on the side wall, thus forming the swivel bearing will.
- the electronics module can then be pivoted about the pivot bearing from this starting position and thus pivoted towards the side wall in an intermediate assembly position and arranged there.
- 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 the pivoting is completed.
- only the advantageous screw connection already mentioned above is provided in this rear area of the housing of the electronic module.
- the pivot bearing thus forms, on the one hand, a rear mechanical mount of the housing of the electronic module on the side wall and additionally provides a particularly advantageous handle during assembly and, in this regard, changing the position of the electronic module.
- the housing of the electronics module viewed in the vertical direction, has support ribs on an underside. With these support ribs, the housing rests on a support on the side wall. This also supports a position fixation in the height direction.
- these support ribs also create a guide so that when the electronics module is brought into the machine room, in particular to initially form the above-mentioned advantageous embodiment with the pivot bearing, the electronics module can be pushed in in a targeted manner.
- the coupling of the pivot bearing elements to the counter pivot bearing elements can thus be carried out in a very easy to assemble manner.
- the housing of the electronics module preferably has a barrier wall to avoid contact between a set of lines 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 wires or cables.
- This barrier wall thus advantageously avoids direct contact between the line set 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.
- Another aspect of the invention relates to a method for mounting an electronic 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 generated.
- This intermediate assembly position there is in particular no grounding contact between the electronic module and an electrically conductive sub-element of the side wall, i.e. there is no electrically conductive connection between these elements in the intermediate assembly position.
- the electronics module is brought into an end position on an assembly path starting from the intermediate assembly position, a grounding contact of the electronics module being connected to an electrically conductive sub-element of the side wall in an electrically conductive and mechanically clamping manner on this assembly path.
- the intermediate assembly position is in particular that in which a pivot bearing, which is advantageously present, is formed between the electronics module and the side wall.
- a pivot bearing which is advantageously present
- the swivel elements are coupled to the counter-swivel elements.
- the electronics module is then pivoted about the pivot bearing towards the side wall.
- the front side of the electronics module viewed in the depth direction is pivoted towards the side wall.
- the assembly path relates in particular to the path between this intermediate assembly position and that position at which the pivoting is completed.
- the housing of the electronic module is preferably pivoted on this assembly path and the clamping connection between the grounding contact and the electrically conductive sub-element is automatically achieved during this pivoting.
- the clamping connection preferably creates a self-retaining pre-fixing position of the electronic module on the side wall before the final assembly of the electronic module on this side wall.
- an additional screw connection is created between the housing of the electronic module and the side wall during assembly after this self-retaining pre-fixing position has been reached.
- this screw connection is produced in the area of the aforementioned clamping connection between the grounding contact and the electrically conductive sub-element.

This machine room is laterally limited by side walls. The household appliance also has an electronics module, which in the Machine room is arranged.

Such a configuration ensures that the electronics module can be arranged in a specific location in the machine room and, in this context, better takes into account both electrical requirements and mechanically stable positioning. The grounding contact and the connection to the electrically conductive sub-element thus simultaneously create a mechanical connection that not only makes contact with one another, but is also provided with a defined application of force in this regard. This creates the clamping connection. In addition, it is provided for this mechanical clamping connection that 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 through the mechanically clamping connection. Safe earthing is thus also achieved.
In einem Ausführungsbeispiel ist vorgesehen, dass der Erdungskontakt als eine in Breitenrichtung des Haushaltsgeräts orientierte Kontaktzunge ausgebildet ist. Die Kontaktzunge weist insbesondere eine in Breitenrichtung orientierte Länge auf, die um ein Vielfaches größer ist, als eine senkrecht zur Breitenrichtung orientierte Breite und/oder Dicke der Kontaktzunge. Damit wird insbesondere ein Plattenteil beziehungsweise ein flächiges Teil bereitgestellt, welches bezüglich der Montage besonders vorteilhaft mit dem elektrisch leitenden Teilelement wirken kann. Beim Montieren kann somit sehr kontinuierlich die klemmende Wirkung aufgebaut werden. Darüber hinaus ist dann auch mit dem elektrisch leitenden Teilelement und dem Erdungskontakt ein besonders zuverlässiges und stabiles elektrisches Kontaktieren ermöglicht.In one 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 perpendicular to the width direction. In this way, in particular a plate part or a flat part is provided which can act particularly advantageously with the electrically conductive sub-element with regard to assembly. During assembly, the clamping effect can therefore be built up very continuously. In addition, a particularly reliable and stable electrical contact is then also made possible with the electrically conductive sub-element and the grounding contact.
Durch eine derartige Ausgestaltung und Anordnung des Erdundkontakts ist auch vorzugsweise eine gewisse Verformungselastizität einhergehend, sodass sich diese Kontaktzunge um eine vertikale Achse elastisch verschwenken kann. Damit kann beim Montieren in besonders vorteilhafter Weise die mechanisch klemmende Verbindung aufgebaut werden. Insbesondere ist diese mechanisch klemmende Verbindung auch dann noch aufrecht erhalten, wenn das Elektronikmodul in der montierten Endlage im Maschinenraum angeordnet ist.Such a configuration and arrangement of the ground and contact is also preferably accompanied by a certain elasticity of deformation, so that this contact tongue can pivot elastically about a vertical axis. With that, the The mechanically clamping connection can be built up in a particularly advantageous manner. In particular, this mechanically clamping connection is still maintained when the electronics module is arranged in the assembled end position in the machine room.
Vorzugsweise ist das elektrisch leitende Teilelement der Seitenwand in Breitenrichtung des Haushaltsgeräts frei kragend orientiert angeordnet. Insbesondere kann dieses elektrisch leitende Teilelement streifenartig oder plattenartig ausgebildet sein und stellt somit ebenfalls vorzugsweise ein flächiges Element dar. Durch diese Ausgestaltung sind in vorteilhafter Weise der Erdungskontakt und das elektrisch leitende Teilelement mit ihren flächigen Erstreckungsebenen im Wesentlichen parallel aufeinander orientiert. Eine großflächige Anlage zwischen dem Erdungskontakt und dem elektrisch leitenden Element ist erreicht. Damit sind zwei spezifische geometrische Elemente mit spezifischen Orientierungen zueinander vorgesehen, die die Erzeugung der Erdungsverbindung einerseits und der mechanisch klemmenden Verbindung andererseits vorteilhaft ermöglicht und auch dann aufrechterhält.The electrically conductive sub-element of the side wall is preferably arranged so as to be cantilevered in the width direction of the household appliance. In particular, this electrically conductive sub-element can be strip-like or plate-like and thus also preferably represents a flat element. This configuration advantageously means that the grounding contact and the electrically conductive sub-element are oriented essentially parallel to one another with their planar extension planes. A large-area contact between the grounding contact and the electrically conductive element is achieved. Two specific geometric elements with specific orientations with respect to one another are thus provided, which advantageously enable and then maintain the creation of the grounding connection on the one hand and the mechanically clamping connection on the other hand.
Insbesondere ist vorgesehen, dass im klemmenden Zustand zwischen dem Erdungskontakt und dem elektrisch leitenden Teilelement ein vorderer Rand des Teilelements an einer Seitenfläche des Erdungskontakts angedrückt ist.In particular, it is provided that in the clamping 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 einem Ausführungsbeispiel ist im klemmenden Zustand das elektrisch leitende Teilelement in einen Spalt einer rückseitigen Koppeleinrichtung des Gehäuses eingedrückt und ist klemmend darin gehalten. Die Koppeleinrichtung weist den Erdungskontakt auf. Der Spalt ist in Breitenrichtung offen. Da durch taucht der Erdungskontakt seitlich in den Spalt ein. Durch diese Anordnung ist eine besonders sichere und stabile klemmende Halterung des Erdungskontakts erreicht. Dieser ist insbesondere in einer Tasche, welche der Spalt darstellt, aufgenommen.In one embodiment, in the clamping state, the electrically conductive sub-element is pressed into a gap in a rear coupling device of the housing and is held therein in a clamping manner. The coupling device has the ground contact. The gap is open in the width direction. The earthing contact dips laterally into the gap. This arrangement achieves a particularly secure and stable clamping mounting of the grounding contact. This is in particular received in a pocket that represents the gap.
Insbesondere ist vorgesehen, dass durch die klemmende Verbindung eine Vorfixierposition des Elektronikmoduls an der Seitenwand vor der Endmontage des Elektronikmoduls an dieser Seitenwand erzeugt ist. Damit ist es in besonderer Vorteilhaftigkeit erreicht, dass eine zusätzliche Befestigungsmöglichkeit des Elektronikmoduls in der Endstellung erzeugt werden kann. Durch die in dem Zusammenhang schon gebildete Vorfixierposition ist es insbesondere ermöglicht, dass das Elektronikmodul zur Endmontage dann nicht mehr zusätzlich durch den Monteur gehalten werden muss. Insbesondere ist die Vorfixierposition eine selbsthaltende Position. Das Montieren von weiteren Befestigungsvorrichtungen ist dann sehr vorteilhaft möglich.In particular, it is provided that the clamping connection creates a pre-fixing position of the electronic module on the side wall before the final assembly of the electronic module on this side wall. In this way, it is particularly advantageous that an additional fastening option for the electronic module can be created in the end position. Through the in that The pre-fixing position that has already been formed in relation to this makes it possible, in particular, that the electronics module no longer has to be additionally held by the fitter for final assembly. In particular, the pre-fixing position is a self-holding position. The installation of further fastening devices is then very advantageously possible.
Vorzugsweise ist vorgesehen, dass das Gehäuse des Elektronikmoduls eine Nische aufweist. In dieser Nische befindet sich der Erdungskontakt. Dadurch ist der Erdungskontakt im gewissen Maße geschützt angeordnet. Insbesondere ist die Nische in Breitenrichtung des Haushaltsgeräts betrachtet offen. Damit kann beim Montieren ein Eingreifen des elektrisch leitenden Teilelements erfolgen. Die Nische ist insbesondere durch den oben genannten Spalt gebildet oder kann den Spalt aufweisen und größer als der Spalt sein. In einem Ausführungsbeispiel ist der Spalt in der Nische nicht vorhanden. Das Rückteil, insbesondere das darin integrierte elektrisch leitende Teilelement, ist dann nur klemmend an der Rückwand angeordnet.It is preferably provided that the housing of the electronics module has a niche. The earthing contact is located in this niche. As a result, the earthing contact is arranged in a protected manner to a certain extent. In particular, the niche is open when viewed in the width direction of the household appliance. In this way, the electrically conductive sub-element can intervene during assembly. The niche is formed in particular 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 sub-element integrated therein, is then only arranged in a clamping manner on the rear wall.
In einem Ausführungsbeispiel ist die Nische durch eine Rückwand begrenzt, wobei die Rückwand mit einem Rückteil der Seitenwand im endmontierten Zustand des Elektronikmoduls an der Seitenwand gekoppelt ist. Insbesondere ist hier eine klemmende und überlappende Anordnung zwischen der Rückwand und dem Rückteil vorgesehen. Dadurch wird die mechanisch stabile Positionierung des Elektronikmoduls an der Seitenwand nochmals unterstützt. Insbesondere ist dadurch auch die vorteilhaft erzeugte Vorfixierposition nochmals verbessert gehalten. Die Rückwand und das Rückteil sind insbesondere plattenförmige Elemente. Sie sind mit ihrer flächigen Erstreckung in Breitenrichtung und in Höhenrichtung orientiert beziehungsweise in dieser Ebene aufgespannt. Durch eine derartige Ausgestaltung ist dann im endmontierten Zustand frontseitig die Verbindung zwischen dem Erdungskontakt und dem elektrisch leitenden Teil abgedeckt. Damit ist diesbezüglich durch die Rückwand und die daran direkt anliegende und gekoppelte Anordnung des Rückteils eine Doppelwand als Abdeckung und Schutz für den Erdungskontakt und das elektrisch leitende Teilelement gebildet.In one embodiment, the niche is delimited by a rear wall, the rear wall being coupled to a rear part of the side wall in the final assembled state of the electronic module 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 electronics module on the side wall. In particular, the advantageously generated pre-fixing position is also kept improved in this way. The rear wall and the rear part are in particular plate-shaped elements. With their two-dimensional extension, they are oriented in the width direction and in the height direction or are spanned in this plane. Such a configuration then covers the connection between the grounding contact and the electrically conductive part on the front side in the finally assembled state. In this regard, a double wall as a cover and protection for the grounding contact and the electrically conductive sub-element is formed by the rear wall and the arrangement of the rear part directly adjacent and coupled to it.
Insbesondere ist das Gehäuse des Elektronikmoduls insbesondere eine Rückwand des Gehäuses mit einem Rückteil der Seitenwand mit einer Schraubverbindung verbunden. Diese Schraubverbindung wird insbesondere im Nachgang zur Erzeugung der vorteilhaft ausgebildeten Vorfixierposition gebildet. Durch diese Schraubverbindung wird die mechanisch stabile Halterung des Elektronikmoduls an der Seitenwand verbessert. Darüber hinaus ist gerade die Verbauung der Schraubverbindung an dieser spezifischen Stelle vorteilhaft, da die überlappende Anordnung zwischen der Rückwand und dem Rückteil zusätzlich verschraubt ist.In particular, 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 in the aftermath of the generation of the trained Vorfixierposition formed. This screw connection improves the mechanically stable mounting of the electronics module on the side wall. In addition, it is precisely the construction of the screw connection at this specific point that is advantageous, since the overlapping arrangement between the rear wall and the rear part is additionally screwed.
Insbesondere weist die Rückwand ein Durchführloch für eine Schraube auf. Insbesondere ist dies auch beim Rückteil vorgesehen. Vorzugsweise weist die Seitenwand einen Schraubdom mit einem Gewinde auf, in welche die Schraube eingeschraubt werden kann. Insbesondere stellt die Rückwand eine frontseitige Begrenzungswand der oben genannten vorteilhaft vorhandenen Nische dar. Damit wird diese Rückwand multifunktionell genutzt.In particular, the rear wall has a through hole for a screw. In particular, this is also provided for the rear part. The side wall preferably has a screw dome with a thread into which the screw can be screwed. In particular, the rear wall represents a front-side delimiting wall of the above-mentioned advantageously existing niche. This rear wall is thus used multifunctionally.
In einem Ausführungsbeispiel ist der Spalt in der Nische nicht vorhanden. Das Rückteil, insbesondere das darin integrierte elektrisch leitende Teilelement, ist dann nur klemmend an der Rückwand angeordnet.In one embodiment, the gap does not exist in the niche. The rear part, in particular the electrically conductive sub-element integrated therein, is then only arranged in a clamping manner on the rear wall.
Insbesondere ist vorgesehen, dass die Schraubverbindung im Bereich der klemmenden Verbindung zwischen dem Erdungskontakt und dem elektrisch leitenden Teilelement gebildet ist. Damit wird örtlich konzentriert die mechanisch stabile Halterung im vorderen Bereich des Elektronikmoduls durch mehrere verschiedene Verbindungen gebildet. Eine besonders stabile Positionierung des Elektronikmoduls in diesem Rückbereich ist dadurch ermöglicht.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 sub-element. In this way, the mechanically stable mounting is locally concentrated in the front area of the electronics module through several different connections. This enables the electronics module to be positioned in a particularly stable manner in this rear area.
Insbesondere ist vorgesehen, dass das Gehäuse des Elektronikmoduls an einer der klemmenden Verbindung gegenüberliegenden Seite mit einem Schwenklager mit der Seitenwand verbunden ist. Insbesondere ist diese gegenüberliegende Seite in Tiefenrichtung betrachtet. Insbesondere stellt diese gegenüberliegende Seite somit eine hintere Seite dar. Durch dieses Schwenklager kann eine besonders einfache und montagefreundliche Anbringung ermöglicht werden. Es kann nämlich zunächst das Elektronikmodul beziehungsweise dessen Gehäuse im Bereich des Schwenklagers gekoppelt werden. Dazu können Schwenke dieser Schwenkverbindung, die am Gehäuse des Elektronikmoduls angeordnet sind, mit Gegenschwenkelementen, die an der Seitenwand angeordnet sind, gekoppelt werden und so das Schwenklager gebildet werden. Im Nachgang kann dann das Elektronikmodul aus dieser Ausgangsstellung um das Schwenklager geschwenkt werden und so in einer Zwischenmontageposition zur Seitenwand hin geschwenkt werden und dort angeordnet werden. Bei dieser Schwenkbewegung kann dann die Kopplung zwischen dem Erdungskontakt und dem elektrisch leitenden Elemente automatisch erfolgen und bei einem weiteren Schwenken dann die klemmende Verbindung diesbezüglich aufgebaut werden. Es ist dann die Vorfixierposition erreicht und das Schwenken abgeschlossen. Im Nachgang wird dann nur noch die bereits oben erwähnte vorteilhafte Verschraubung in diesem Rückbereich des Gehäuses des Elektronikmoduls vorgesehen. Das Schwenklager bildet somit einerseits eine rückseitige mechanische Halterung des Gehäuses des Elektronikmoduls an der Seitenwand und liefert zusätzlich eine besonders vorteilhafte Handhabe bei der Montage und diesbezüglich Positionsveränderung des Elektronikmoduls.In particular, it is provided that the housing of the electronics module is connected to the side wall with 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. This pivot bearing enables particularly simple and easy-to-assemble attachment. This is because the electronics module or its housing can first be coupled in the area of the pivot bearing. For this purpose, swivels of this swivel connection, which are arranged on the housing of the electronics module, can be coupled with counter-swivel elements which are arranged on the side wall, thus forming the swivel bearing will. Subsequently, the electronics module can then be pivoted about the pivot bearing from this starting position and thus pivoted towards the side wall in an intermediate assembly position 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 the pivoting is completed. Subsequently, only the advantageous screw connection already mentioned above is provided in this rear area of the housing of the electronic module. The pivot bearing thus forms, on the one hand, a rear mechanical mount of the housing of the electronic module on the side wall and additionally provides a particularly advantageous handle during assembly and, in this regard, changing the position of the electronic module.
In einer vorteilhaften Ausführung weist das Gehäuse des Elektronikmoduls in Höhenrichtung betrachtet an einer Unterseite Auflagerippen auf. Mit diesen Auflagerippen liegt das Gehäuse auf einer Auflage der Seitenwand auf. Dadurch ist auch eine Positionsfixierung in Höhenrichtung zusätzlich unterstützt. Insbesondere ist durch diese Auflagerippen auch eine Führung geschaffen, sodass beim Verbringen des Elektronikmoduls in den Maschinenraum, insbesondere um zunächst die oben genannte vorteilhafte Ausgestaltung mit dem Schwenklager auszubilden, das Elektronikmodul gezielt eingeschoben werden kann. Damit kann das Koppeln der Schwenklagerelemente mit den Gegenschwenklagerelementen sehr montagefreundlich erfolgen.In an advantageous embodiment, the housing of the electronics module, viewed in the vertical direction, has support ribs on an underside. With these support ribs, the housing rests on a support on the side wall. This also supports a position fixation in the height direction. In particular, these support ribs also create a guide so that when the electronics module is brought into the machine room, in particular to initially form the above-mentioned advantageous embodiment with the pivot bearing, the electronics module can be pushed in in a targeted manner. The coupling of the pivot bearing elements to the counter pivot bearing elements can thus be carried out in a very easy to assemble manner.
Vorzugsweise weist das Gehäuse des Elektronikmoduls eine Barrierewand zur Kontaktvermeidung zwischen einem Leitungssatz und einer aus einem elektrisch leitenden Material ausgebildeten Begrenzungswand des Maschinenraums auf. Ein diesbezüglicher Leitungssatz betrifft ein oder mehrere elektrische Leitungen beziehungsweise Kabel. Durch diese Barrierewand wird somit in vorteilhafter Weise eine direkte Kontaktierung zwischen dem Leitungssatz und der elektrisch leitenden Begrenzungswand vermieden. Diesbezüglich unerwünschte elektrische Kontaktierungen und daraus resultierende Funktionsbeeinträchtigungen des Haushaltsgeräts können somit zuverlässig vermieden werden.The housing of the electronics module preferably has a barrier wall to avoid contact between a set of lines 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 wires or cables. This barrier wall thus advantageously avoids direct contact between the line set 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.
Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zur Montage eines Elektronikmoduls an einer Seitenwand, die einen Maschinenraum eines Haushaltsgeräts begrenzt. Das Elektronikmodul wird im Maschinenraum positioniert. Ein Gehäuse des Elektronikmoduls wird mit dieser Seitenwand gekoppelt, sodass dadurch eine Zwischenmontagestellung beziehungsweise eine Zwischenmontageposition erzeugt wird. In dieser Zwischenmontagestellung besteht insbesondere kein Erdungskontakt des Elektronikmoduls mit einem elektrisch leitenden Teilelement der Seitenwand, d.h. es liegt zwischen diesen Elementen in der Zwischenmontagestellung keine elektrisch leitende Verbindung vor. Das Elektronikmodul wird auf einem Montageweg ausgehend von der Zwischenmontagestellung in eine Endstellung verbracht, wobei auf diesem Montageweg ein Erdungskontakt des Elektronikmoduls mit einem elektrisch leitenden Teilelement der Seitenwand elektrisch leitend und mechanisch klemmend verbunden wird. Die Zwischenmontagestellung ist insbesondere diejenige, bei welcher ein vorteilhaft vorhandenes Schwenklager zwischen dem Elektronikmodul und der Seitenwand ausgebildet ist. Dies bedeutet, dass diesbezüglich in der Zwischenmontagestellung die Schwenkelemente mit den Gegenschwenkelementen gekoppelt sind. Ausgehend von dieser Zwischenmontagestellung wird dann das Verschwenken des Elektronikmoduls um das Schwenklager zur Seitenwand hin durchgeführt. Insbesondere wird dabei die in Tiefenrichtung betrachtet vordere Seite des Elektronikmoduls zur Seitenwand hin geschwenkt. Der Montageweg bezieht sich in dem Zusammenhang insbesondere auf den Weg zwischen dieser Zwischenmontagestellung und derjenigen Position, bei welcher das Verschwenken abgeschlossen ist.Another aspect of the invention relates to a method for mounting an electronic 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 generated. In this intermediate assembly position, there is in particular no grounding contact between the electronic module and an electrically conductive sub-element of the side wall, i.e. there is no electrically conductive connection between these elements in the intermediate assembly position. The electronics module is brought into an end position on an assembly path starting from the intermediate assembly position, a grounding contact of the electronics module being connected to an electrically conductive sub-element of the side wall in an electrically conductive and mechanically clamping manner on this assembly path. The intermediate assembly position is in particular that in which a pivot bearing, which is advantageously present, is formed between the electronics module and the side wall. This means that in this regard, in the intermediate assembly position, the swivel elements are coupled to the counter-swivel elements. Starting from this intermediate assembly position, the electronics module is then pivoted about the pivot bearing towards 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 that position at which the pivoting is completed.
Vorzugsweise wird das Gehäuse des Elektronikmoduls auf diesem Montageweg geschwenkt und bei diesem Schwenken automatisch die klemmende Verbindung zwischen dem Erdungskontakt und dem elektrisch leitenden Teilelement erreicht.The housing of the electronic module is preferably pivoted on this assembly path and the clamping connection between the grounding contact and the electrically conductive sub-element is automatically achieved during this pivoting.
Vorzugsweise wird durch die klemmende Verbindung eine selbsthaltende Vorfixierposition des Elektronikmoduls an der Seitenwand vor der Endmontage des Elektronikmoduls an dieser Seitenwand erzeugt. Insbesondere wird bei dem Montieren nachfolgend auf das Erreichen dieser selbsthaltenden Vorfixierposition eine zusätzliche Schraubverbindung zwischen dem Gehäuse des Elektronikmoduls und der Seitenwand erzeugt. Insbesondere wird diese Schraubverbindung im Bereich der genannten klemmenden Verbindung zwischen dem Erdungskontakt und dem elektrisch leitenden Teilelement erzeugt.The clamping connection preferably creates a self-retaining pre-fixing position of the electronic module on the side wall before the final assembly of the electronic module on this side wall. In particular, an additional screw connection is created 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 aforementioned clamping connection between the grounding contact and the electrically conductive sub-element.

Damit ein Geräteleitungssatz die Begrenzungswand 11 und/oder die Begrenzungswand 12 nicht berührt, ist an dem Gehäuse 10 des Elektronikmoduls 9 die bereits angesprochene Barrierewand 34 ausgebildet.Since the
Besonders vorteilhaft ist die vorgesehene Ausgestaltung auch dahingehend, dass keine zusätzliche Erdungsschraub zum Herstellen einer Erdungsverbindung erforderlich ist.

Insbesondere entfallen dadurch auch benötigte Federringe und Scheiben, die bei einer derartigen Verwendung einer Erdungsschraube vorgesehen sind.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.
