Das erfindungsgemäße Haushaltskältegerät umfasst den zum Lagern von Lebensmitteln vorgesehenen kühlbaren Innenraum und eine wärmeisolierte Wandung, die eine den kühlbaren Innenraum begrenzende Innenhaut und einen an der dem kühlbaren Innenraum abgewandten Seite der Innenhaut anliegenden Isolierschaum umfasst. Insbesondere umfasst das Haushaltskältegerät ein wärmeisoliertes Gehäuse, das mit dem Isolierschaum wärmeisoliert ist. Das Gehäuse umfasst einen Innenbehälter, der den zum Lagern von Lebensmitten vorgesehenen kühlbaren Innenraum begrenzt. Die wärmeisolierte Wandung ist z.B. ein Teil des Gehäuses, sodass der Innenbehälter die genannte Innenhaut darstellt und somit z.B. das Hinterlegteil am Innenbehälter befestigt ist.The household refrigeration appliance according to the invention comprises the coolable interior intended for storing food and a heat-insulated wall which comprises an inner skin delimiting the coolable interior and an insulating foam lying on the side of the inner skin facing away from the coolable interior. In particular, the household refrigerator includes a heat-insulated housing that is heat-insulated with the insulating foam. The housing includes an inner container that limits the coolable interior space intended for storing food. The heat-insulated wall is, for example, a part of the housing, so that the inner container represents the inner skin mentioned and thus, for example, the backing part is attached to the inner container.

Das erfindungsgemäße Haushaltskältegerät kann z.B. ein mit einem Isolierschaum wärmeisoliertes Türblatt umfassen, das schwenkbar relativ zum Gehäuse gelagert ist. Im geschlossenen Zustand verschließt dieses Türblatt den kühlbaren Innenraum und im geöffneten Zustand des Türblatts ist der kühlbare Innenraum zugänglich. Das Türblatt ist wärmeisoliert und umfasst eine dem kühlbaren Innenraum zugewandte Innenhaut. Die wärmeiisolierte Wandung ist z.B. das Türblatt, sodass das Hinterlegteil z.B. an der Innenhaut des Türblatts befestigt ist.The household refrigeration device according to the invention can, for example, comprise a door leaf that is thermally insulated with an insulating foam and is pivotably mounted relative to the housing. When closed, this door leaf closes the coolable interior and when the door leaf is open, the coolable interior is accessible. The door leaf is thermally insulated and includes an inner skin facing the coolable interior. The heat-insulated wall is, for example, the door leaf, so that the backing part is attached, for example, to the inner skin of the door leaf.

Das erfindungsgemäße Haushaltskältegerät kann z.B. eine Schublade umfassen, die eine mit einem Isolierschaum wärmeisolierte Frontplatte umfasst. Die Schublade kann zumindest teilweise aus dem kühlbaren Innenraum herausgezogen werden und verschließt im in den kühlbaren Innenraum hineingeschobenen Zustand den kühlbaren Innenraum. Die Frontplatte der Schublade ist wärmeisoliert und umfasst eine dem kühlbaren Innenraum zugewandte Innenhaut. Die wärmeisolierte Wandung ist z.B. die Frontplatte der Schublade, sodass das Hinterlegteil z.B. an der Innenhaut der Frontplatte der Schublade befestigt ist.The household refrigeration appliance according to the invention can, for example, comprise a drawer which includes a front panel which is thermally insulated with an insulating foam. The drawer can be at least partially 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, for example, the front panel of the drawer, so that the backing part is attached, for example, to the inner skin of the front panel of the drawer.

Um den kühlbaren Innenraum auf die gewünschte Temperatur zu kühlen, umfasst das Haushaltskältegerät eine Kältevorrichtung z.B. in Form eines dem Fachmann im Prinzip bekannten Kältemittelkreislaufs.In order to cool the coolable interior to the desired temperature, the household refrigeration device comprises a refrigeration device, for example in the form of a refrigerant circuit known in principle to those skilled in the art.

Das erfindungsgemäße Haushaltskältegerät ist z.B. ein Haushaltskühlgerät. In diesem Fall wird der kühlbare Innenraum auf Temperaturen größer als 0°C gekühlt. Das erfindungsgemäße Haushaltskältegerät kann auch ein Haushaltsgefriergerät sein. In diesem Fall wird der kühlbare Innenraum auf Temperaturen kleiner als 0°C gekühlt. Das erfindungsgemäße Haushaltskältegerät kann aber auch eine Gefrier-Kühlkombination sein.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.

Das Hinterlegteil des erfindungsgemäßen Haushaltskältegeräts ist z.B. aus Kunststoff und umfasst die durch die Öffnung in der Innenhaut zugängliche Vorderseite. Das erfindungsgemäße Haushaltskältegerät umfasst die elektrische und/oder elektronische Komponente.The rear part of the household refrigeration appliance according to the invention is made, for example, of plastic and includes the front side which is accessible through the opening in the inner skin. The household refrigerator according to the invention includes the electrical and/or electronic component.

Das Haushaltskältegerät umfasst den an der dem kühlbaren Innenraum abgewandten Seite der Innenhaut anliegenden Isolierschaum. Die dem kühlbaren Innenraum abgewandte Seite der Innenhaut bildet somit eine schaumseitige Oberfläche der Innenhaut.The household refrigerator includes the insulating foam on the side of the inner skin facing away from the coolable interior. The side of the inner skin facing away from the coolable interior thus forms a foam-side surface of the inner skin.

Die Vorderseite des Hinterlegteils kann eine Aufnahme zum Befestigen der elektrischen und/oder elektronischen Komponente aufweisen.The front of the backing part can have a receptacle for attaching the electrical and/or electronic component.

Die elektrische und/oder elektronische Komponente ist z.B. eine elektrische Kontaktiervorrichtung, beispielsweise ein elektrischer Stecker oder eine elektrische Buchse, die über die Vorderseite des Hinterlegteil zugänglich ist. Die elektrische Kontaktiervorrichtung ist insbesondere mit einem elektrischen Kabel verbunden, das insbesondere im Isolierschaum eingeschäumt ist. Die Aufnahme für die elektrische bzw. elektronische Komponente kann durch die Rückseite des Hintelegteils zugänglich sein und die Rückseite des Hinterlegteils kann einen Deckel umfassen.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 include a lid.

Das erfindungsgemäße Haushaltskältegerät kann ein weiteres elektrisches Kabel umfassen, das an einem seiner Enden eine elektrischen Gegenkontaktiervorrichtung umfasst, die die elektrischen Kontaktiervorrichtung elektrisch kontaktiert.The household refrigeration appliance according to the invention can comprise a further electrical cable, which comprises an electrical counter-contacting device at one of its ends, which electrically contacts the electrical contacting device.

Das erfindungsgemäße Haushaltskältegerät umfasst die Abdeckung, welche am Hinterlegteil befestigt ist und die Vorderseite des Hinterlegteils und somit die elektrische bzw. elektronische Komponente abdeckt. Die Abdeckung ist vorzugsweise am Hinterlegteil lösbar befestigt.The household refrigeration appliance 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.

Da die Abdeckung die Vorderseite abdeckt und somit auch die elektrische und/oder elektronische Komponente, ist es sinnvoll, dass diese für einen verbesserten Brandschutz schwer entflammbar ist. Da jedoch die Abdeckung auch mit dem kühlbaren Innenraum in Kontakt steht, sollte diese auch für Lebensmittel unbedenklich sein. Die Abdeckung für das Hinterlegteil des erfindungsgemäßen Haushaltskältegerätes umfasst daher die äußere Abdeckung und die innere Abdeckung. Die innere Abdeckung ist an der äußeren Abdeckung befestigt und ist zwischen der äußeren Abdeckung und der Vorderseite des Hinterlegteils angeordnet.Since the cover covers the front and therefore also the electrical and/or electronic components, 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 rear part of the household refrigeration appliance 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 member.

Die innere Abdeckung bzw. ihrer der Vorderseite des Hinterlegteils zugewandten Seite ist insbesondere der elektrischen bzw. elektronischen Komponente zugewandt und ist für den verbesserten Brandschutz aus einem schwer entflammbaren Material gefertigt. Die der Vorderseite des Hinterlegteils zugewandte Seite der inneren Abdeckung kann z.B. mit einer schwer entflammbaren Beschichtung versehen sein. Vorzugsweise ist jedoch die innere Abdeckung als Ganzen aus einem schwer entflammbaren Kunststoff gefertigt. Geeignete Kunststoffe sind dem Fachmann im Prinzip bekannt.The inner cover or its side facing the front of the backing part faces in particular 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 in principle known to those skilled in the art.

Die äußere Abdeckung bzw. ihrer dem kühlbaren Innenraum zugewandten Seite steht mit dem kühlbaren Innenraum in Kontakt und kann daher mit den im kühlbaren Innenraum gelagerten Lebensmitteln in Kontakt stehen. Daher ist die äußere Abdeckung, zumindest deren dem kühlbaren Innenraum zugewandte Seite aus einem für Lebensmittel unbedenklichen Material gefertigt. Die dem kühlbaren Innenraum zugewandte Seite der äußeren Abdeckung kann z.B. mit einer für Lebensmittel unbedenklichen Beschichtung versehen sein. Vorzugsweise ist jedoch die äußere Abdeckung als Ganzen aus einem für Lebensmittel unbedenklichen Kunststoff gefertigt. Geeignete Kunststoffe sind dem Fachmann im Prinzip bekannt.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. Therefore, the outer cover, at least the side facing the coolable interior, is made of a food-safe material. The side of the outer cover facing the coolable interior can, for example, be provided with a coating that is safe for food. However, the outer cover as a whole is preferably made of a food-safe plastic. Suitable plastics are in principle known to those skilled in the art.

Das erfindungsgemäße Haushaltskältegerät ist insbesondere derart ausgeführt, dass die elektrische bzw. die elektronische Komponente z.B. in Form von wenigstens einem elektrischen Steckverbinder in einem für einen Benutzer zugänglichen Bereich des Haushaltskältegerätes in Form des kühlbaren Innenraums zugänglich ist. Daher umfasst das erfindungsgemäße Haushaltskältegerät die Abdeckung für das Hinterlegteil, um die elektrische bzw. elektronische Komponente gegen Berührung zu schützen.The household refrigeration appliance according to the invention is in particular designed in such a way that the electrical or electronic component, for example in the form of at least one electrical plug connector, is accessible in a user-accessible area of the household refrigeration appliance in the form of the coolable interior. Therefore, the household refrigeration appliance according to the invention includes the cover for the backing part in order to protect the electrical or electronic component against contact.

Zusätzlich müssen ggf. weitere Anforderungen erfüllt werden, wie z.B. normative Anforderungen. Eine solche Anforderung könnte ggf. die IEC / UL 60335 darstellen, weshalb erfindungsgemäß die innere Abdeckung, zumindest ihre der Vorderseite des Hinterlegteils zugewandten Seite aus dem schwer entflammbaren Material gefertigt ist. Das schwer entflammbare Material erfüllt insbesondere die IEC / UL 60335 oder entsprechende Vorgaben.In addition, other requirements may need 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 meets IEC / UL 60335 or corresponding specifications.

Wegen der Position der Abdeckung sollten zusätzlich lebensmittelrechtliche Anforderung erfüllt sein, da die im kühlbaren Innenraum gelagerten Lebensmittel die Abdeckung berühren können. Da die gängigen flammgeschützten Materialien diese Anforderungen nicht erfüllen, umfasst die Abdeckung erfindungsgemäß die schwer entflammbare innere Abdeckung und die äußere Abdeckung mit Eignung für Lebensmittelkontakt.Due to the position of the cover, additional food law requirements should be met, as 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 food contact.

Die Abdeckung ist insbesondere zweilagig ausgeführt, indem es die äußere Abdeckung und die an der äußeren Abdeckung befestigte innere Abdeckung umfasst.The cover is in particular designed in two layers, comprising the outer cover and the inner cover attached to the outer cover.

Gemäß einer Ausführungsform des erfindungsgemäßen Haushaltskältegerätes umfasst die Vorderseite seitliche Wände, die eine Befestigungsvorrichtung aufweisen. Die Abdeckung ist vorzugsweise mit ihrer äußeren Abdeckung mittels der Befestigungsvorrichtung am Hinterlegteil befestigt.According to one embodiment of the household refrigeration appliance according to the invention, the front side comprises side walls which have a fastening device. The cover is preferably attached to the backing part with its outer cover by means of the fastening device.

Für eine relativ einfache Befestigung der Abdeckung am Hinterlegteil ist gemäß einer Variante des erfindungsgemäßen Haushaltskältegerätes die Befestigungsvorrichtung als an den äußeren Seiten der seitlichen Wände angeformte Nuten ausgebildet. Die Abdeckung, insbesondere die äußere Abdeckung umfasst dann insbesondere angeformte Ausbuchtungen, mit denen die Abdeckung bzw. die äußere Abdeckung formschlüßig in den Nuten verschieblich gelagert ist. Um die Abdeckung im befestigten Zustand am Hinterlegteil zu fixieren, können vorzugsweise die Nuten und die Ausbuchtungen eine Rastvorrichtung umfassen. Die Ausbuchtungen der Abdeckung bzw. der äußeren Abdeckung sind insbesondere schlittenförmige Ausbuchtungen.For a relatively simple attachment of the cover to the backing part, according to a variant of the household refrigeration appliance according to the invention, the fastening device is designed as grooves formed on the outer sides of the side walls. The cover, in particular the outer cover, then comprises, in particular, molded bulges with which the cover or the outer cover is mounted in a form-fitting manner so that it can be moved in the grooves. In order to fix the cover in the attached 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.

Die äußere Abdeckung ist vorzugsweise im Querschnitt u-förmig ausgebildet und umgreift somit insbesondere das Hinterlegteil u-förmig.The outer cover is preferably U-shaped in cross section and therefore surrounds the backing part in a U-shaped manner.

Für eine nochmals vereinfachte Befestigung der Abdeckung am Hinterlegteil weisen gemäß einer Variante des erfindungsgemäßen Haushaltskältegerätes die Nuten der Abdeckung zugewandte Wände auf, welche mit Aussparungen versehen sind, um für ein Befestigen der Abdeckung am Hinterlegteil die Ausbuchtungen der Abdeckung bzw. der äußeren Abdeckung von oben in die Nuten zu führen, um anschließend die Abdeckung derart in eine Verschiebrichtung zu verschieben, sodass die Ausbuchtungen formschlüßig in die Nuten greifen und insbesondere die Rastvorrichtung für die Fixierung der Abdeckung am Hinterlegteil verrastet.For a further simplified attachment of the cover to the backing part, according to a variant of the household refrigeration device according to the invention, the grooves have walls facing the cover, which are provided with recesses in order to fasten the cover to the backing part in the bulges of the cover or the outer cover from above to guide the grooves in order to then move the cover in a displacement direction in such a way that the bulges engage in the grooves in a form-fitting manner and in particular the locking device for fixing the cover on the backing part locks.

Aufgrund dieser Ausgestaltung ergibt sich ein relativ einfaches Verfahren zum Herstellen dieses erfindungsgemäßen, aufweisend folgende Verfahrensschritte:

  • 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
  • anschließendes Verschieben der Abdeckung in einer Verschiebrichtung, sodass die Ausbuchtungen formschlüßig in die Nuten greifen und insbesondere die Rastvorrichtung für die Fixierung der Abdeckung am Hinterlegteil verrastet.
This configuration results in a relatively simple process for producing this according to the invention, comprising the following process steps:
  • Providing the back part,
  • 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
  • Moving the cover onto 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 displacement direction so that the bulges engage positively in the grooves and in particular the locking device for fixing the cover on the backing part locks.

Nach einer bevorzugten Ausführungsform des erfindungsgemäßen Haushaltskältegerätes ist die Rastvorrichtung als an den Ausbuchtungen in Richtung Abdeckung vorgespanntes Federelement ausgebildet, die im befestigten Zustand der Abdeckung mit Aussparungen der äußeren Abdeckung zugewandten Wände der Nuten verrasten, um eine Bewegung der Abdeckung bzw. der äußeren Abdeckung entgegen der Verschiebungsrichtung zu verhindern.According to a preferred embodiment of the household refrigeration appliance according to the invention, the locking device is designed as a spring element which is prestressed on the bulges in the direction of the cover, which, when the cover is in the attached state, engage with walls of the grooves facing recesses in the outer cover in order to prevent movement of the cover or the outer cover against the To prevent displacement direction.

Um die am Hinterlegteil befestigte Abdeckung zerstörungsfrei vom Hinterlegteil zu entfernen, kann die äußere Abdeckung Öffnungen umfassen, die mit den vorgespannten Federelementen fluchten, um durch diese Öffnungen ein Entrasten der verrasteten vorgespannten Federelemente zu ermöglichen. Dies erfolgt vorzugsweise mit einem speziellen Werkzeug.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 prestressed spring elements in order to enable the latched, prestressed spring elements to be unlocked through these openings. This is preferably done with a special tool.

Um die innere Abdeckung an der äußeren Abdeckung relativ einfach zu befestigen, ist gemäß einer Ausführungsform des erfindungsgemäßen Haushaltskältegerätes die innere Abdeckung für das Befestigen an der äußeren Abdeckung an der äußeren Abdeckung verschieblich gelagert, sodass die innere Abdeckung und die äußere Abdeckung im am Hinterlegteil befestigten Zustand, d.h. in einer Befestigungsposition ineinander verschoben sind. Um die verschiebliche Lagerung zu realisieren, kann die äußere Abdeckung nutförmige Aufnahmen umfassen, bezüglich derer die innere Abdeckung für das Befestigen an der äußeren Abdeckung an der äußeren Abdeckung verschieblich gelagert ist.In order to attach 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 displaceably mounted on the outer cover for attachment to the outer cover, so that the inner cover and the outer cover are in the on Backing part fastened state, ie are moved 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 displaceably mounted on the outer cover for attachment to the outer cover.

Die innere Abdeckung ist vorzugsweise flach ausgeführt.The inner cover is preferably flat.

Gemäß einer bevorzugten Variante des erfindungsgemäßen Haushaltskältegerätes weisen die innere Abdeckung und die äußere Abdeckung Rastmittel auf, die die innere Abdeckung wahlweise an der äußeren Abdeckung in einer Befestigungsposition, in der die innere Abdeckung und die äußere Abdeckung ineinander verschoben sind, und in einer zum Befestigen der Abdeckung am Hinterlegteil vorgesehenen Montageposition fixieren, in der die innere Abdeckung und die äußere Abdeckung nur teilweise ineinander verschoben sind.According to a preferred variant of the household refrigeration appliance according to the invention, the inner cover and the outer cover have locking means which selectively attach the inner cover to the outer cover in a fastening position in which the inner cover and the outer cover are moved into one another, and in a position for fastening the Fix the cover in the mounting position provided on the backing part, in which the inner cover and the outer cover are only partially shifted into one another.

Die Rastmittel sind z.B. als an der der äußeren Abdeckung zugewandten Seite der inneren Abdeckung angeformte erste und zweite Ausbuchtungen ausgebildet, die mit einer an der der inneren Abdeckung zugewandten Seite der äußeren Abdeckung ausgebildeten Vertiefung in Wirkverbindung zu stehen vermögen. Ist die Vertiefung mit der ersten Ausbuchtung verrastet, dann ist die innere Abdeckung an der äußeren Abdeckung in der Befestigungsposition fixiert und die innere und die äußere Abdeckungen sind ineinander verschoben. Ist die Vertiefung mit der zweiten Ausbuchtung verrastet, dann ist die innere Abdeckung an der äußeren Abdeckung in der für das Befestigen der Abdeckung am Hinterlegteil vorgesehenen Montageposition fixiert.The locking means are, for example, formed 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 to the outer cover in the fastening position and the inner and outer covers are moved 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 intended for attaching the cover to the backing part.

Die Rastmittel sind z.B. als an der der inneren Abdeckung zugewandten Seite der äußeren Abdeckung angeformte erste und zweite Ausbuchtungen ausgebildet, die mit einer an der der äußeren Abdeckung zugewandten Seite der inneren Abdeckung ausgebildeten Vertiefung in Wirkverbindung zu stehen vermögen. Ist die Vertiefung mit der ersten Ausbuchtung verrastet, dann ist die innere Abdeckung an der äußeren Abdeckung in der Befestigungsposition fixiert und die innere und die äußere Abdeckungen sind ineinander verschoben. Ist die Vertiefung mit der zweiten Ausbuchtung verrastet, dann ist die innere Abdeckung an der äußeren Abdeckung in der für das Befestigen der Abdeckung am Hinterlegteil vorgesehenen Montageposition fixiert.The locking means are, for example, formed 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 to the outer cover in the fastening position and the inner and outer covers are moved into one another. Is the depression with the second bulge latched, then the inner cover is fixed to the outer cover in the mounting position intended for attaching the cover to the backing part.

Sind nun die innere und die äußere Abdeckung derart ausgebildet, dass sie verschieblich zueinander gelagert sind, sodass die innere Abdeckung und die äußere Abdeckung im am Hinterlegteil befestigten Zustand ineinander verschoben sind, und weisen die innere und die äußere Abdeckung die Rastmittel auf, so kann der Schritt des Verschiebens der Abdeckung in die Verschiebrichtung vorzugsweise folgende Verfahrensschritte aufweisen:

  • 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 covers are designed in such a way that they are displaceably mounted relative to one another, so that the inner cover and the outer cover are moved into one another when they are attached to the backing part, and the inner and outer covers have the locking means, then the The step of moving the cover in the direction of displacement preferably has the following process steps:
  • Displacing the cover in the direction of displacement, with the inner and outer covers in the assembly position, until the inner cover interacts 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 displacing the outer cover in the displacement direction relative to the backing part until the outer cover interacts at least indirectly 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 relative to the inner cover is that it is moved from the assembly position into the fastening position, and in particular the locking device for fixing the cover on the backing part locks.

Für eine nochmals vereinfachte Montage kann das Hinterlegteil eine Führung und eine Stoppvorrichtung umfassen. In diesem Fall weist das erfindungsgemäße Verfahren vorzugsweise folgende Verfahrensschritte auf:

  • 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.
For further simplified assembly, the backing part can include a guide and a stop device. In this case, the method according to the invention preferably has the following process steps:
  • Moving the cover in an unfolded state along the guide of the backing part attached to the heat-insulated wall in the direction of displacement until it reaches the stop device,
  • subsequently pivoting the cover in the direction of the backing part attached to the heat-insulated wall, so that the bulges of the outer cover are guided into the grooves from above, and
  • then moving the cover in the direction of displacement so that the bulges of the outer cover engage positively in the grooves and in particular the locking device for fixing the cover on the backing part is locked.

Beim Erreichen der Stoppvorrichtung erhält eine Person, die die Abdeckung am Hinterlegteil befestigt, eine haptische Rückmeldung, und kann daraufhin in relativ einfacher Wiese die Abdeckung auf das Hinterlegteil Schwenken, um danach die Abdeckung am Hinterlegteil zu befestigen.When the stop device is reached, a person who is attaching the cover to the backing part receives haptic feedback and can then pivot the cover onto the backing part in a relatively simple manner in order to then attach the cover to the backing part.

Vorzugsweise steht während des Bewegens der Abdeckung im aufgeklappten Zustand entlang der Führung des an der wärmeisolierten Wandung befestigten Hinterlegteils die innere Abdeckung mit der Führung in Kontakt.Preferably, during the movement of the cover in the unfolded state along the guide of the backing part attached to the heat-insulated wall, the inner cover is in contact with the guide.

Die Stoppvorrichtung ist vorzugsweise als Einbuchtungen im Hinterlegteil, insbesondere in der Führung ausgeführt. Dadurch verhindert die Stoppvorrichtung nach dem Schwenken der Abdeckung in Richtung Hinterlegteil nicht, dass die Abdeckung in der Verschiebrichtung weiter verschoben werden kann, sodass die Ausbuchtungen der äußeren Abdeckung formschlüßig in die Nuten greifen und insbesondere die Rastvorrichtung für die Fixierung der Abdeckung am Hinterlegteil verrastet.The stop device is preferably designed as indentations in the backing part, in particular in the guide. As a result, after pivoting the cover in the direction of the backing part, the stop device does not prevent the cover from being moved further in the direction of displacement, so that the bulges of the outer cover engage in the grooves in a form-fitting manner and in particular the locking device for fixing the cover on the backing part locks.

Die Fig. 1 zeigt ein Haushaltskältegerät 1 in einer perspektivischen Darstellung.The Fig. 1 shows a household refrigeration device 1 in a perspective view.

Das Haushaltskältegerät 1 weist ein mit einem Isolierschaum wärmeisoliertes Gehäuse 2 auf. Das Gehäuse 2 umfasst einen Innenbehälter 3, der einen zum Lagern von Lebensmitteln vorgesehenen kühlbaren Innenraum 4 begrenzt. Der Innenbehälter 3 ist insbesondere aus Kunststoff gefertigt und umfasst eine dem kühlbaren Innenraum 4 zugewandte Seite 3a und eine dem kühlbaren Innenraum 4 abgewandte bzw. schaumseitige Seite 3b, an dem der nicht dargestellte Isolierschaum anliegt.The household refrigerator 1 has a housing 2 that is thermally insulated with an insulating foam. The housing 2 includes an inner container 3, which delimits a coolable interior 4 intended for storing food. The inner container 3 is in particular made of plastic and comprises a side 3a facing the coolable interior 4 and a side 3b facing away from the coolable interior 4 or on the foam side, on which the insulating foam, not shown, rests.

Das wärmeisolierte Gehäuse 2 umfasst demnach eine wärmeisolierte Wandung mit einer dem kühlbaren Innenraum 4 zugewandten Innenhaut in Form des Innenbehälters 3.The heat-insulated housing 2 therefore comprises a heat-insulated wall with an inner skin facing the coolable interior 4 in the form of the inner container 3.

Das Haushaltskältegerät 1 weist im Falle des vorliegenden Ausführungsbeispiels ein relativ zum Gehäuse 2 schwenkbar gelagertes Türblatt 5 zum Verschließen des kühlbaren Innenraums 4 auf. Das Türblatt 5 ist insbesondere bezüglich einer nicht dargestellten, vertikal verlaufenden Achse schwenkbar gelagert. Bei geöffnetem Türblatt 5 ist der kühlbare Innenraum 4 zugänglich. Das Türblatt 5 ist mit einem Isolierschaum wärmeisoliert und umfasst eine dem kühlbaren Innenraum 4 zugewandte Innenhaut 5a. Das Türblatt 5 ist somit ebenfalls ein Beispiel einer wärmeisolierten Wandung mit einer dem kühlbaren Innenraum 4 zugewandten Innenhaut.In the case of the present exemplary embodiment, the household refrigerator 1 has a door leaf 5 which is pivotally mounted relative to the housing 2 for closing the coolable interior 4. The door leaf 5 is pivotally mounted in particular with respect to a vertical axis, not shown. When the door leaf 5 is open, the coolable interior 4 is accessible. The door leaf 5 is thermally insulated with an insulating foam and includes an inner skin 5a facing the coolable interior 4. The door leaf 5 is therefore also an example of a heat-insulated wall with an inner skin facing the coolable interior 4.

An der Innenhaut 5a des Türblatts 5 sind im Falle des vorliegenden Ausführungsbeispiels mehrere Türabsteller 6 zum Lagern von Lebensmitteln angeordnet. Im kühlbaren Innenraum 4 sind insbesondere mehrere Fachböden 7 zum Lagern von Lebensmitteln angeordnet und im unteren Bereich des kühlbaren Innenraums 4 ist insbesondere eine Schublade 8 angeordnet, in der ebenfalls Lebensmittel gelagert werden können.In the case of the present exemplary embodiment, several door racks 6 for storing food are arranged on the inner skin 5a of the door leaf 5. In the coolable interior 4 there are in particular several shelves 7 for storing food arranged and in the lower area of the coolable interior 4 there is in particular a drawer 8 arranged in which food can also be stored.

Im Falle des vorliegenden Ausführungsbeispiels umfasst das Haushaltskältegerät 1 einen weiteren kühlbaren Innenraum 4a, der unterhalb des kühlbaren Innenraums 4 angeordnet ist und ebenfalls zum Lagern von Lebensmitteln vorgesehen ist.In the case of the present exemplary embodiment, the household refrigerator 1 comprises a further coolable interior 4a, which is arranged below the coolable interior 4 and is also intended for storing food.

Im Falle des vorliegenden Ausführungsbeispiels umfasst das Haushaltskältegerät 1 eine Schublade 9, die einen nach oben geöffneten Behälter 10 zum Lagern der Lebensmitteln und eine am Behälter 10 befestigte Frontplatte 11 umfasst. Die Frontplatte ist mit einem Isolierschaum wärmeisoliert und umfasst eine dem weiteren kühlbaren Innenraum 4a zugewandte Innenhaut 11a. Die Schublade 9 kann zumindest teilweise aus dem weiteren kühlbaren Innenraum 4a herausgezogen werden und zum Verschließen des weiteren Innenraums 4a in diesen hineingeschoben werden. Die Frontplatte 11 der Schublade 9 ist somit ein weiteres Beispiel einer wärmeisolierten Wandung mit einer dem weiteren kühlbaren Innenraum 4a zugewandten Innenhaut.In the case of the present exemplary embodiment, the household refrigeration appliance 1 comprises a drawer 9 which comprises an upwardly opened container 10 for storing the food and a front panel 11 attached to the container 10. The front panel is thermally insulated with an insulating foam and includes an inner skin 11a facing the further coolable interior 4a. The drawer 9 can be at least partially pulled out of the further coolable interior 4a and pushed into it to close the further interior 4a. The front panel 11 of the drawer 9 is therefore another example of a heat-insulated wall with an inner skin facing the further coolable interior 4a.

Das Haushaltskältegerät 1 umfasst eine Kältevorrichtung 12 z.B. in Form eines nicht näher gezeigten Kältemittelkreislaufs zum Kühlen des kühlbaren Innenraums 4 und des weiteren kühlbaren Innenraums 4a.The household refrigeration device 1 includes a refrigeration device 12, for example in the form of a refrigerant circuit (not shown) for cooling the coolable interior 4 and the further coolable interior 4a.

Im Falle des vorliegenden Ausführungsbeispiels wird der kühlbare Innenraum 4 auf Temperaturen über 0°C und der weitere kühlbare Innenraum 4a auf Temperaturen kleiner als 0°C gekühlt. Das Haushaltskältegerät 1 ist somit Im Falle des vorliegenden Ausführungsbeispiels eine Gefrier-Kühlkombination.In the case of the present exemplary embodiment, the coolable interior 4 is cooled to temperatures above 0 ° C and the further coolable interior 4a to temperatures less than 0 ° C. In the case of the present exemplary embodiment, the household refrigerator 1 is therefore a freezer-refrigerator combination.

Das Haushaltskältegerät 1 umfasst ein Hinterlegteil 21, das zumindest teilweise in einer wärmeisolierten Wandung des Haushaltskältegerätes 1 eingeschäumt und an der Innenhaut dieser wärmeisolierten Wandung befestigt ist.

Die Fig. 8 zeigt zudem eine Seitenansicht in geschnittener Darstellung, in der die Montageposition zu sehen ist.In the case of the present exemplary embodiment, the inner cover 30 and the outer cover 29 have locking means which selectively fix the inner cover 30 and the outer cover in the fastening position or in a mounting position intended for fastening the cover 22 to the backing part 21, in which the inner cover 30 and the outer cover 29 are only partially shifted into one another. The Fig. 3 shows the inner cover 30 and the outer cover 29 in the fastening position. The mounting position of the inner cover 30 and the outer cover 29 is in the Fig. 7 shown. The Fig. 8 also shows a side view in a sectional view, in which the assembly position can be seen.

Im Falle des vorliegenden Ausführungsbeispiels sind die Rastmittel als an der der äußeren Abdeckung 29 zugewandten Seite 33 der inneren Abdeckung 30 angeformte erste und zweite Ausbuchtungen 31, 32 ausgebildet, die mit einer an der der inneren Abdeckung 30 zugewandten Seite 29b der äußeren Abdeckung 29 ausgebildeten Vertiefung 34 in Wirkverbindung zu stehen vermögen. Ist diese Vertiefung 34 mit der ersten Ausbuchtung 31 verrastet, dann ist die innere Abdeckung 30 an der äußeren Abdeckung 29 in der Befestigungsposition fixiert und die innere und die äußere Abdeckungen 30, 29 sind ineinander verschoben. Ist die Vertiefung 34 mit der zweiten Ausbuchtung 32 verrastet, wie dies in der Fig. 8 zu sehen ist, dann ist die innere Abdeckung 30 in der für das Befestigen der Abdeckung 22 am Hinterlegteil 21 vorgesehenen Montageposition an der äußeren Abdeckung 29 fixiert.In the case of the present exemplary embodiment, the locking means are formed as first and second bulges 31, 32 formed on the side 33 of the inner cover 30 facing the outer cover 29, which are formed with a recess formed on the side 29b of the outer cover 29 facing the inner cover 30 34 are able to be in effective connection. If this recess 34 is locked with the first bulge 31, then the inner cover 30 is fixed to the outer cover 29 in the fastening position and the inner and outer covers 30, 29 are moved into one another. Is the recess 34 locked with the second bulge 32, as shown in the Fig. 8 can be seen, then the inner cover 30 is fixed to the outer cover 29 in the mounting position provided for attaching the cover 22 to the backing part 21.

Erfindungsgemäß umfasst die Vorderseite 23 des Hinterlegteils 21 seitliche Wände 35, die eine Befestigungsvorrichtung aufweisen. Die Abdeckung 22 ist mit ihrer äußeren Abdeckung 29 mittels der Befestigungsvorrichtung am Hinterlegteil 21 befestigt.According to the invention, the front side 23 of the backing part 21 comprises side walls 35 which have a fastening device. The cover 22 is fastened with its outer cover 29 to the backing part 21 by means of the fastening device.

Erfindungsgemäß ist die Befestigungsvorrichtung als an den äußeren Seiten der seitlichen Wände 35 angeformte Nuten 36 ausgebildet. Im Falle des vorliegenden Ausführungsbeispiels umfasst das Hinterlegteil 21 eine Führung 37, entlang derer die Abdeckung 22 für deren Befestigung am Hinterlegteil 21 geführt wird, sodass die innere Abdeckung 30 mit einem Bereich 38 während dieser Bewegung mit der Führung 37 in Kontakt steht. Die Führung 37 wird insbesondere durch Ränder der seitlichen Wände 35 gebildet.According to the invention, the fastening device is designed as grooves 36 formed on the outer sides of the side walls 35. In the case of the present exemplary embodiment, the backing part 21 comprises a guide 37 along which the cover 22 is guided for its attachment to the backing part 21, so that the inner cover 30 with an area 38 is in contact with the guide 37 during this movement. The guide 37 is formed in particular by edges of the side walls 35.

Die Figuren 9 bis 16 veranschaulichen die Befestigung der Abdeckung 22 am Hinterlegteil 21.The Figures 9 to 16 illustrate the attachment of the cover 22 to the backing part 21.

Erfindungsgemäß sind an der äußere Abdeckung 29 z.B. in der Fig. 13 gezeigte Ausbuchtungen 41 angeformt, mit denen die äußere Abdeckung 29 formschlüßig in den Nuten 36 des Hinterlegteils 21 verschieblich gelagert werden kann. Um die Abdeckung 22 im befestigten Zustand am Hinterlegteil 21 zu fixieren, können vorzugsweise die Nuten 36 und die Ausbuchtungen 41 eine Rastvorrichtung z.B. in Form von an den Ausbuchtungen 41 der äußeren Abdeckung 29 angeformten vorgespannten Federelementen 41a aufweisen. Die Ausbuchtungen 41 der äußeren Abdeckung 29 sind insbesondere schlittenförmig.According to the invention, on the outer cover 29, for example in the Fig. 13 Bulges 41 shown are formed, with which the outer cover 29 can be slidably mounted in a form-fitting manner in the grooves 36 of the backing part 21. In order to fix the cover 22 in the attached state on the backing part 21, the grooves 36 and the bulges 41 can preferably have a locking device, for example in the form of prestressed spring elements 41a formed on the bulges 41 of the outer cover 29. The bulges 41 of the outer cover 29 are in particular slide-shaped.

Die äußere Abdeckung 29 ist vorzugsweise im Querschnitt u-förmig ausgebildet und umgreift somit insbesondere das Hinterlegteil 21 u-förmig.The outer cover 29 is preferably U-shaped in cross section and therefore surrounds the backing part 21 in a U-shaped manner.

Im Falle des vorliegenden Ausführungsbeispiels weisen die Nuten 36 der Abdeckung 22 zugewandte Wände 36a auf, welche mit Aussparungen 36b versehen sind, um für ein Befestigen der Abdeckung 22 am Hinterlegteil 21 die Ausbuchtungen 41 der äußeren Abdeckung 29 von oben in die Nuten 36 zu führen.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.

Für die Befestigung der Abdeckung 22 am Hinterlegteil 21 wird im Falle des vorliegenden Ausführungsbeispiels die Abdeckung 22 in einem in der Fig. 9 gezeigten aufgeklappten Zustand entlang der Führung 37 des am Gehäuse 2 befestigten Hinterlegteils 21 in der Verschieberichtung V bis zum Erreichen einer Stoppvorrichtung verschoben, siehe Fig. 10. Die Stoppvorrichtung ist insbesondere als in der Fig. 11 besser erkennbare Einbuchtungen 39 in der Führung 37 bzw. in den Rändern der seitlichen Wände 35 ausgeführt.In order to attach the cover 22 to the backing part 21, in the case of the present exemplary embodiment, the cover 22 is in one in the Fig. 9 shown unfolded state along the guide 37 of the backing part 21 attached to the housing 2 in the displacement direction V until a stop device is reached, see Fig. 10 . The stopping device is in particular as in the Fig. 11 more recognizable Indentations 39 are made in the guide 37 or in the edges of the side walls 35.

Während des aufgeklappten Zustands der Abdeckung 22 und während ihrer Bewegung entlang der Verschieberichtung V steht die innerer Abdeckung 30 mit ihrem Bereich 38 mit der Führung 37 des Hinterlegteils 21 in Kontakt. Außerdem befindet sich die innerer Abdeckung 30 relativ zur äußeren Abdeckung 29 in der Montageposition.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 in the mounting position relative to the outer cover 29.

Beim Erreichen der Stoppvorrichtung bzw. der Einbuchtungen 39 in den Rändern der seitlichen Wände 35 des Hinterlegteils 21 erfährt eine die Abdeckung 22 am Hinterlegteil 21 befestigende Person eine haptische Rückmeldung und beendet die Bewegung der Abdeckung 22 in der Verschieberichtung V, um die Abdeckung 22 in Richtung des Hinterlegteils 21 zu schwenken. Dies ist in der Fig. 10 mit einem Pfeil S angedeutet.When reaching the stop device or the indentations 39 in the edges of the side walls 35 of the backing part 21, a person fastening the cover 22 to the backing part 21 experiences haptic feedback and stops the movement of the cover 22 in the displacement direction V in order to move the cover 22 in the direction of the backing part 21 to pivot. This is in the Fig. 10 indicated with an arrow S.

Durch das Schwenken der Abdeckung 22 in Richtung des Pfeils S werden die Ausbuchtungen 41 der äußeren Abdeckung 29 durch Aussparungen 36b der Wände 36a der Nuten 36 geführt. Die innere Abdeckung 30 befindet sich relativ zur äußeren Abdeckung immer noch in der Montageposition. Dieser Montagezustand ist in den Figuren 12 bis 14 gezeigt.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.

Im Falle des vorliegenden Ausführungsbeispiels sind an der äußeren Abdeckung 29 weitere schlittenförmige Ausbuchtungen 42 angeformt.In the case of the present exemplary embodiment, further slide-shaped bulges 42 are formed on the outer cover 29.

Anschließend wird die Abdeckung 22 weiter in der Verschiebrichtung V verschoben, sodass die Ausbuchtungen 41 und die weiteren Ausbuchtungen 42 der äußeren Abdeckung 30 formschlüssig in die Nuten 36 greifen. Außerdem befinden sich die innere Abdeckung 29 und die äußere Abdeckung 30 in der Montageposition befinden.The cover 22 is then moved further in the displacement direction 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 mounting position.

Die Abdeckung 22 wird zunächst solange in der Verschieberichtung V verschoben, bis ein Bereich 43 der inneren Abdeckung 29 mit einem Bereich 44 des Hinterlegteils 21 derart zusammenwirkt, dass ein weiteres Verschieben der inneren Abdeckung 29 in der Verschieberichtung V relativ zum Hinterlegteil 21 verhindert wird. Der Bereich 43 der inneren Abdeckung 29 umgreift insbesondere den Bereich 44 des Hinterlegteils 21.
