Another aspect of the invention relates to a method for producing the household refrigerator according to the invention, having the following method steps:

• Provision of the deposit,
• Fixing the backing part in the area of the opening of the inner skin so that the front of the backing part is accessible through the opening,
• Providing the side of the inner skin facing away from the coolable interior with an insulating foam as part of a foaming step, whereby the backing part is partially foamed in the insulating foam in order to attach it to the heat-insulated wall, and
• Attach the cover to the backing part.

The household refrigerator according to the invention comprises the coolable interior provided for storing food and a heat-insulated wall which comprises an inner skin delimiting the coolable interior and an insulating foam lying against the side of the inner skin facing away from the coolable interior. In particular, the household refrigerator comprises a thermally insulated housing which is thermally insulated with the insulating foam. The housing comprises an inner container which delimits the coolable interior space provided for storing foodstuffs. The heat-insulated wall is, for example, a part of the housing, so that the inner container represents the named inner skin and thus, for example, the backing part is attached to the inner container.

The household refrigerator according to the invention can, for example, comprise a door leaf which is thermally insulated with an insulating foam and which is pivotably mounted relative to the housing. In the closed state, this door leaf closes the coolable interior space and in the open state of the door leaf the coolable interior space is accessible. The door leaf is thermally insulated and includes an inner skin facing the coolable interior. The heat-insulated wall is e.g. the door leaf, so that the backing part is attached to the inner skin of the door leaf, for example.

The domestic refrigeration appliance according to the invention can, for example, comprise a drawer which comprises a front panel which is thermally insulated with an insulating foam. The drawer can at least partially be pulled out of the coolable interior and closes the coolable interior when pushed into the coolable interior. The front panel of the drawer is thermally insulated and includes an inner skin facing the coolable interior. The heat-insulated wall is e.g. the front panel of the drawer, so that the backing part is e.g. attached to the inner skin of the front panel of the drawer.

In order to cool the coolable interior to the desired temperature, the household refrigeration device comprises a refrigeration device, e.g. in the form of a refrigerant circuit known in principle to the person skilled in the art.

The household refrigerator according to the invention is, for example, a household refrigerator. In this case, the coolable interior is cooled to temperatures greater than 0 ° C. The household refrigerator according to the invention can also be a household freezer. In this case, the coolable interior is cooled to temperatures below 0 ° C. The household refrigerator according to the invention can also be a freezer-refrigerator combination.

The backing part of the household refrigerator according to the invention is made of plastic, for example, and comprises the front side accessible through the opening in the inner skin. The household refrigerator according to the invention comprises the electrical and / or electronic component.

The household refrigerator comprises the insulating foam lying on the side of the inner skin facing away from the coolable interior. The side of the inner skin facing away from the coolable inner space thus forms a foam-side surface of the inner skin.

The front of the backing part can have a receptacle for fastening the electrical and / or electronic component.

The electrical and / or electronic component is, for example, an electrical contacting device, for example an electrical plug or an electrical socket, which is accessible via the front of the backing part. The electrical contacting device is connected in particular to an electrical cable which is foamed in particular in the insulating foam. The receptacle for the electrical or electronic component can be accessible through the back of the backing part and the back of the backing part can comprise a cover.

The household refrigeration appliance according to the invention can comprise a further electrical cable, which at one of its ends comprises an electrical counter-contacting device which makes electrical contact with the electrical contacting device.

The household refrigerator according to the invention comprises the cover which is attached to the backing part and covers the front of the backing part and thus the electrical or electronic component. The cover is preferably releasably attached to the backing part.

Since the cover covers the front and thus also the electrical and / or electronic component, it makes sense that it is flame retardant for improved fire protection. However, since the cover is also in contact with the coolable interior, it should also be safe for food. The cover for the backing part of the household refrigerator according to the invention therefore comprises the outer cover and the inner cover. The inner cover is attached to the outer cover and is disposed between the outer cover and the front of the backing part.

The inner cover or its side facing the front side of the backing part is in particular facing the electrical or electronic component and is made of a flame-retardant material for improved fire protection. The side of the inner cover facing the front of the backing part can, for example, be provided with a flame-retardant coating. However, the inner cover is preferably made as a whole from a flame-retardant plastic. Suitable plastics are known in principle to the person skilled in the art.

The outer cover or its side facing the coolable interior is in contact with the coolable interior and can therefore be in contact with the food stored in the coolable interior. The outer cover, at least its side facing the coolable interior, is therefore made of a material that is harmless to food. The side of the outer cover facing the coolable interior space can, for example, be provided with a food-safe coating. Preferably, however, the outer cover is made as a whole from a plastic that is harmless to food. Suitable plastics are known in principle to the person skilled in the art.

The household refrigerator according to the invention is designed in particular in such a way that the electrical or electronic component is accessible, e.g. in the form of at least one electrical connector, in an area of the household refrigerator that is accessible to a user in the form of the coolable interior. The household refrigerator according to the invention therefore comprises the cover for the backing part in order to protect the electrical or electronic component against contact.

In addition, other requirements may have to be met, such as normative requirements. Such a requirement could possibly be represented by IEC / UL 60335, which is why, according to the invention, the inner cover, at least its side facing the front of the backing part, is made of the flame-retardant material. The flame-retardant material particularly fulfills IEC / UL 60335 or corresponding specifications.

Because of the position of the cover, food law requirements should also be met, since the food stored in the coolable interior covers the cover can touch. Since the common flame-retardant materials do not meet these requirements, the cover according to the invention comprises the flame-retardant inner cover and the outer cover suitable for contact with food.

The cover is designed in particular in two layers, in that it comprises the outer cover and the inner cover attached to the outer cover.

According to one embodiment of the household refrigerator according to the invention, the front side comprises side walls which have a fastening device. The cover is preferably fastened with its outer cover by means of the fastening device on the backing part.

For a relatively simple attachment of the cover to the backing part, according to a variant of the household refrigerator according to the invention, the attachment device is designed as grooves formed on the outer sides of the lateral walls. The cover, in particular the outer cover, then comprises, in particular, molded-on bulges with which the cover or the outer cover is mounted in the grooves in a form-fitting manner. In order to fix the cover in the fastened state on the backing part, the grooves and the bulges can preferably comprise a latching device. The bulges of the cover or the outer cover are in particular slide-shaped bulges.

The outer cover is preferably designed to be U-shaped in cross section and thus in particular surrounds the backing part in a U-shape.

For an even more simplified attachment of the cover to the backing part, according to a variant of the household refrigeration device according to the invention, the grooves of the cover have facing walls, which are provided with recesses to allow the bulges of the cover or the outer cover from above to be attached to the backing part to guide the grooves in order to then move the cover in a displacement direction in such a way that the bulges engage positively in the grooves and in particular the latching device for fixing the cover on the backing part is locked.

• Bereitstellen des Hintelegteils,
• Fixieren des Hinterlegteils im Bereich der Öffnung des Innenhaut, sodass die Vorderseite des Hinterlegteils durch die Öffnung zugänglich ist,
• Versehen der dem kühlbaren Innenraum abgewandten Seite der Innenhaut mit einem Isolierschaum im Rahmen eines Schäumungsschrittes, wodurch das Hinterlegteil teilweise im Isolierschaum eingeschäumt wird, um es an der wärmeisolierten Wandung zu befestigen, und
• Bewegen der Abdeckung an das an der wärmeisolierten Wandung befestigte Hinterlegteil, sodass die Ausbuchtungen der Abdeckung bzw. der äußeren Abdeckung von oben in die Nuten geführt werden, und

• Moving the cover to the backing part attached to the heat-insulated wall so that the bulges of the cover or the outer cover are guided into the grooves from above, and
• subsequent displacement of the cover in a direction of displacement, so that the bulges engage positively in the grooves and, in particular, the locking device for fixing the cover on the backing part is locked.

According to a preferred embodiment of the household refrigerator according to the invention, the latching device is designed as a spring element pretensioned at the bulges in the direction of the cover, which, when the cover is fastened, lock with recesses of the outer cover facing walls of the grooves to prevent movement of the cover or the outer cover against the To prevent shift direction.

In order to remove the cover attached to the backing part from the backing part in a non-destructive manner, the outer cover can comprise openings which are aligned with the pretensioned spring elements in order to enable the latched pretensioned spring elements to be unlatched through these openings. This is preferably done with a special tool.

In order to fasten the inner cover to the outer cover relatively easily, according to one embodiment of the household refrigeration appliance according to the invention, the inner cover is slidably mounted for fastening to the outer cover on the outer cover, so that the inner cover and the outer cover are at the Backing part fastened state, that is, are shifted into one another in a fastening position. In order to realize the displaceable mounting, the outer cover can comprise groove-shaped receptacles, with respect to which the inner cover is slidably mounted on the outer cover for attachment to the outer cover.

The inner cover is preferably made flat.

According to a preferred variant of the household refrigeration appliance according to the invention, the inner cover and the outer cover have latching means which the inner cover optionally on the outer cover in a fastening position in which the inner cover and the outer cover are shifted into one another, and in one for fastening the Fix cover on the backing part provided assembly position in which the inner cover and the outer cover are only partially shifted into one another.

The latching means are formed, for example, as first and second bulges formed on the side of the inner cover facing the outer cover, which are able to be in operative connection with a recess formed on the side of the outer cover facing the inner cover. If the recess is locked with the first bulge, then the inner cover is fixed in the fastening position on the outer cover and the inner and the outer covers are shifted into one another. If the recess is locked with the second bulge, then the inner cover is fixed to the outer cover in the assembly position provided for fastening the cover to the backing part.

The latching means are formed, for example, as first and second bulges formed on the side of the outer cover facing the inner cover, which are able to be in operative connection with a recess formed on the side of the inner cover facing the outer cover. If the recess is locked with the first bulge, then the inner cover is fixed on the outer cover in the fastening position and the inner and the outer covers are shifted into one another. Is the indentation with the second bulge locked, then the inner cover is fixed to the outer cover in the mounting position provided for attaching the cover to the backing part.

• Verschieben der Abdeckung in der Verschiebrichtung, wobei sich die innere und die äußere Abdeckung in der Montageposition befinden, bis die innere Abdeckung mit dem Hinterlegteil derart zusammenwirkt, dass ein weiteres Verschieben der inneren Abdeckung in der Verschieberichtung relativ zum Hinterlegteil verhindert wird, und
• weiteres Verschieben der äußeren Abdeckung in der Verschiebungsrichtung relativ zum Hinterlegteil, bis die äußere Abdeckung zumindest indirekt mit dem Hinterlegteil derart zusammenwirkt, dass ein weiteres Verschieben der äußeren Abdeckung in der Verschieberichtung relativ zum Hinterlegteil verhindert wird, wodurch die äußere Abdeckung relativ zur inneren Abdeckung derart verschoben wird, dass sie von der Montageposition in die Befestigungsposition verschoben wird, und insbesondere die Rastvorrichtung für die Fixierung der Abdeckung am Hinterlegteil verrastet.

If the inner and outer cover are now designed such that they are mounted displaceably to one another, so that the inner cover and the outer cover are shifted into one another in the state attached to the backing part, and if the inner and outer cover have the latching means, the can Step of moving the cover in the direction of displacement preferably have the following method steps:

• Moving the cover in the direction of displacement, the inner and the outer cover being in the assembly position until the inner cover cooperates with the backing part in such a way that further displacement of the inner cover in the direction of displacement relative to the backing part is prevented, and
• further displacement of the outer cover in the displacement direction relative to the backing part until the outer cover at least indirectly interacts with the backing part in such a way that further displacement of the outer cover in the displacement direction relative to the backing part is prevented, whereby the outer cover is displaced in this way relative to the inner cover is that it is moved from the mounting position into the fastening position, and in particular the latching device for fixing the cover on the backing part is locked.

• Bewegen der Abdeckung in einem aufgeklappten Zustand entlang der Führung des an der wärmeisolierten Wandung befestigten Hinterlegteils in der Verschieberichtung bis zum Erreichen der Stoppvorrichtung,
• anschließendes Schwenken der Abdeckung in Richtung des an der wärmeisolierten Wandung befestigten Hinterlegteils, sodass die Ausbuchtungen der äußeren Abdeckung von oben in die Nuten geführt werden, und
• anschließendes Verschieben der Abdeckung in der Verschieberichtung, sodass die Ausbuchtungen der äußeren Abdeckung formschlüßig in die Nuten greifen und insbesondere die Rastvorrichtung für die Fixierung der Abdeckung am Hinterlegteil verrastet.

In the case of the present exemplary embodiment, the grooves 36 have walls 36a facing the cover 22, which are provided with recesses 36b in order to guide the bulges 41 of the outer cover 29 from above into the grooves 36 for fastening the cover 22 to the backing part 21.

For the attachment of the cover 22 to the backing part 21, the cover 22 is in the case of the present embodiment in a Fig. 9 The unfolded state shown is displaced along the guide 37 of the backing part 21 fastened to the housing 2 in the displacement direction V until a stop device is reached, see FIG Fig. 10 . The stop device is particularly as in the Fig. 11 more recognizable Indentations 39 are made in the guide 37 or in the edges of the side walls 35.

During the unfolded state of the cover 22 and during its movement along the displacement direction V, the inner cover 30 is in contact with its area 38 with the guide 37 of the backing part 21. In addition, the inner cover 30 is located relative to the outer cover 29 in the assembly position.

Upon reaching the stop device or the indentations 39 in the edges of the side walls 35 of the backing part 21, a person attaching the cover 22 to the backing part 21 receives a haptic feedback and ends the movement of the cover 22 in the displacement direction V, around the cover 22 in the direction of the backing part 21 to pivot. This is in the Fig. 10 indicated by an arrow S.

By pivoting the cover 22 in the direction of the arrow S, the bulges 41 of the outer cover 29 are guided through recesses 36b in the walls 36a of the grooves 36. The inner cover 30 is still in the mounting position relative to the outer cover. This assembly state is in the Figures 12 to 14 shown.

In the case of the present exemplary embodiment, further slide-shaped bulges 42 are formed on the outer cover 29.

The cover 22 is then shifted further in the direction of displacement V, so that the bulges 41 and the further bulges 42 of the outer cover 30 engage in the grooves 36 in a form-fitting manner. In addition, the inner cover 29 and the outer cover 30 are in the assembly position.

The cover 22 is initially shifted in the displacement direction V until an area 43 of the inner cover 29 interacts with an area 44 of the backing part 21 in such a way that further displacement of the inner cover 29 in the shifting direction V relative to the backing part 21 is prevented. The area 43 of the inner cover 29 encompasses in particular the area 44 of the backing part 21. This state is in FIG Fig. 15 shown.

Subsequently, the outer cover 29 is moved further in the direction of displacement V relative to the backing part 21 and relative to the inner cover 30, whereby the outer cover 29 is shifted relative to the inner cover 29 from the mounting position into the fastening position. As a result, the pretensioned spring elements 41a engage with the backing part 21, see FIG Fig. 16 and the Fig. 3 .

In the case of the present exemplary embodiment, the outer cover 29 comprises openings 40 which are aligned with the pretensioned spring elements 41a in order to enable the latched pretensioned spring elements 41a to be unlocked through these openings 40. This is preferably done with a special tool.
