Die Erfindung betrifft ein Kältegerät mit einem Elektronikgehäuse.
Kältegeräte, insbesondere als Haushaltsgeräte ausgebildete Kältegeräte, sind bekannt und werden zur Haushaltsführung in Haushalten oder im Gastronomiebereich eingesetzt, um verderbliche Lebensmittel und/oder Getränke bei bestimmten Temperaturen zu lagern.
Es sind Kältegeräte bekannt, bei denen ein Elektronikgehäuse zur Aufnahme z.B. eines Netzteils und/oder einer Steuerung des Kältegerätes in einem Top-Panel des Kältegerätes angeordnet ist. Ferner sind Kältegeräte bekannt, bei denen die Elektronik im Maschinenraum des Kältegeräts angeordnet ist, in dem auch der Verdichter des Kältegeräts angeordnet ist. Jedoch nimmt hier das Elektronikgehäuse Bauraum in Anspruch, der das Nutzvolumen des Kältegeräts reduziert.
The invention relates to a refrigeration device with an electronics housing.
Refrigeration appliances, in particular designed as household appliances refrigerators are known and are used to housekeeping in households or in the catering sector to store perishable food and / or drinks at certain temperatures.
There are refrigerators are known in which an electronics housing for receiving, for example, a power supply and / or a control of the refrigeration device is arranged in a top panel of the refrigerator. Further, refrigerators are known in which the electronics are arranged in the machine room of the refrigerator, in which the compressor of the refrigerator is arranged. However, here takes the electronics housing space, which reduces the useful volume of the refrigerator.

JPH06294577A offenbart ein Kältegerät nach dem Oberbegriff des Anspruchs 1JPH06294577A discloses a refrigerator according to the preamble of claim 1

Es ist daher die der Erfindung zugrunde liegende Aufgabe, ein Kältegerät mit einem vergrößerten Nutzvolumen bereitzustellen.
Diese Aufgabe wird durch den Gegenstand mit den Merkmalen nach dem unabhängigen Anspruch gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche, der Beschreibung und der Zeichnungen.
Die vorliegende Erfindung basiert auf der Erkenntnis, dass Abschnitte im Isolationsbereich des Kühlgutbehälters des Kältegerätes als Bauraum zur Unterbringung von Funktionskomponenten des Kältegeräts genutzt werden können.
Die erfindungsgemäße Aufgabe wird durch ein Kältegerät mit einem Elektronikgehäuse gemäß Anspruch 1 gelöst, wobei das Elektronikgehäuse in einem Isolationsbereich eines Kühlgutbehälters angeordnet ist. Dadurch wird der technische Vorteil erreicht, dass bisher ungenutzter Raum im Isolationsbereich des Kühlgutbehälters, d.h. in einem vorzugsweise ausgeschäumten Abschnitt des Kühlgutbehälters genutzt wird. Somit ist der Bauraumbedarf reduziert und das Nutzvolumen des Kältegeräts vergrößert.
It is therefore the object underlying the invention to provide a refrigeration device with an increased useful volume.
This object is achieved by the subject matter having the features of the independent claim. Advantageous developments are subject of the dependent claims, the description and the drawings.
The present invention is based on the recognition that sections in the insulation region of the refrigerated goods container of the refrigeration device can be used as installation space for accommodating functional components of the refrigeration device.
The object of the invention is achieved by a refrigeration device with an electronics housing according to claim 1, wherein the electronics housing is arranged in an isolation region of a refrigerated goods container. As a result, the technical advantage is achieved that previously unused space in the isolation area of the refrigerated goods, ie in a preferably foamed portion of the refrigerated goods is used. Thus, the space requirement is reduced and increases the useful volume of the refrigerator.

Unter einem Kältegerät wird insbesondere ein Haushaltsgerät verstanden, also ein Kältegerät, das zur Haushaltsführung in Haushalten oder im Gastronomiebereich eingesetzt wird, und insbesondere dazu dient, Lebensmittel und/oder Getränke bei bestimmten Temperaturen zu lagern, wie beispielsweise ein Kühlschrank, ein Gefrierschrank, eine Kühl-/Gefrierkombination, eine Gefriertruhe oder ein Weinkühlschrank.A refrigeration device is understood in particular to be a household appliance, that is to say a refrigeration device that is used for household purposes in households or in the gastronomy sector, and in particular serves to store food and / or drinks at specific temperatures, such as, for example, a refrigerator, a freezer, a refrigerator - / Freezer, a freezer or a wine fridge.

In einer vorteilhaften Ausführungsform weist das Kältegerät einen Rückwandabschnitt auf, und das Elektronikgehäuse ist im Rückwandabschnitt angeordnet. Zwar ist durch diese Positionierung des Elektronikgehäuses unter Umständen eine längere Kabelführung notwendig, als wenn das Elektronikgehäuse direkt dort positioniert wird, wo die mit dem Elektronikgehäuse zu verbindenden Bauteile (z.B. Bedienelemente, Heizelemente, elektrische Motoren, Anzeigeelemente, Pumpen für Wasserspender) angeordnet sind. Diese Ausführungsform beruht jedoch auf der Erkenntnis, dass eine durch das Einbringen des Elektronikgehäuses in den Isolationsbereich zwangsläufig resultierende Verschlechterung der Isolationswirkung dann am geringsten ist, wenn das Elektronikgehäuse im Rückwandabschnitt angeordnet wird. Dies deshalb, da die (mögliche) Dicke des Isolationsbereiches im Rückwandabschnitt deutlich größer ist, als z.B. jene in einer Tür des Kältegeräts oder in einem Deckenabschnitt des Kältegeräts.In an advantageous embodiment, the refrigeration device has a rear wall section, and the electronics housing is arranged in the rear wall section. Although this positioning of the electronics housing may require longer cable routing than if the electronics housing is positioned directly where the components to be connected to the electronics housing (e.g., controls, heating elements, electric motors, indicators, water dispenser pumps) are located. However, this embodiment is based on the knowledge that a deterioration of the insulation effect necessarily resulting from the introduction of the electronics housing into the insulation area is lowest when the electronics housing is arranged in the rear wall section. This is because the (possible) thickness of the isolation region in the back wall section is significantly greater than e.g. those in a door of the refrigerator or in a ceiling portion of the refrigerator.

In einer weiteren vorteilhaften Ausführungsform ist das Elektronikgehäuse in einem Kantenabschnitt des Kältegeräts angeordnet. Dadurch wird der technische Vorteil erreicht, dass das Elektronikgehäuse in einem Übergangsbereich z.B. zwischen dem Rückwandabschnitt des Kältegeräts und einer seiner Seitenwände mit einer besonders dicken Isolationsschicht angeordnet ist, so dass durch das Elektronikgehäuse die Isolierwirkung der Isolationsschicht nicht wesentlich reduziert ist.In a further advantageous embodiment, the electronics housing is arranged in an edge portion of the refrigeration device. This achieves the technical advantage that the electronics housing in a transition region, e.g. is arranged between the rear wall portion of the refrigerator and one of its side walls with a particularly thick insulating layer, so that is not significantly reduced by the electronics housing, the insulating effect of the insulating layer.

In einer weiteren vorteilhaften Ausführungsform ist das Elektronikgehäuse mit einem Abstand (A) beabstandet von einer Seitenwand des Kältegeräts angeordnet. Dadurch wird der technische Vorteil erreicht, dass zu geringe Spaltmaße zwischen Elektronikgehäuse und Seitenwand vermieden werden, die beim Ausschäumen Schaumlunker und einen damit verbundenen Einzug von Seitenwänden des Kühlgutbehälters verursachen können.In a further advantageous embodiment, the electronics housing is arranged at a distance (A) spaced from a side wall of the refrigeration device. As a result, the technical advantage is achieved that too small clearances between the electronics housing and the side wall are avoided, which can cause foam bubbles during foaming and an associated collection of side walls of the refrigerated goods.

Gemäß der Erfindung weist das Elektronikgehäuse eine Abstützrippe auf, wobei die Abstützrippe bei einem ausgeschäumten Kühlgutbehälter einen Mindestabstand von dem Kühlgutbehälter aufweist. Mittels der Abstützrippe kann sich das Elektronikgehäuse vor dem Ausschäumen an dem Kühlgutbehälter abstützen, insbesondere wenn z.B. während der Montage des Kühlgeräts Komponenten in das Elektronikgehäuse von Hand eingebaut werden oder eine Rückwandpappe auf das Elektronikgehäuse geklebt wird. Nach dem Ausschäumen jedoch, hebt sich das, z.B. im Rückwandabschnitt angeordnete, Elektronikgehäuse von dem Kühlgutbehälter durch den Schaumdruck dauerhaft ab. Dadurch wird der technische Vorteil erreicht, dass es keine Kältebrücke zwischen dem Elektronikgehäuse und dem Kühlgutbehälter gibt, die die Bildung von Kondenswasser begünstigen könnte. Die Abstützrippe erstreckt sich, z.B. fingerartig oder stabförmig, von dem Elektronikgehäuse nach außen hin weg. Möglich ist auch zwei oder mehrere Abstützrippen vorzusehen. Insbesondere sofern das Elektronikgehäuse mit einem ersten Elektronikgehäuserand an einer Seitenwand des Kühlgerätes, z.B. durch Schrauben, befestigt wird, können zwei Abstützrippen an einem dem ersten Elektronikgehäuserand gegenüberliegenden zweiten Elektronikgehäuserand vorgesehen werden.
In einer weiteren vorteilhaften Ausführungsform sind in dem Elektronikgehäuse ein Netzteil und/oder eine Steuerung des Kältegeräts aufgenommen. Dadurch wird der technische Vorteil erreicht, dass Funktionskomponenten zum Betrieb des Kältegeräts in dem Elektronikgehäuse sicher aufgenommen sind.
In einer weiteren vorteilhaften Ausführungsform sind das Netzteil und/oder die Steuerung in einem Handling-Gehäuse aufgenommen. Dadurch wird der technische Vorteil erreicht, dass während der Montage des Elektronikgehäuses durch das Handling-Gehäuse die Montage des Netzteils und/oder der Steuerung vereinfacht ist.
In einer weiteren vorteilhaften Ausführungsform weist das Elektronikgehäuse einen Grundkörper und einen Deckel auf, wobei als Abdichtung zwischen dem Grundkörper und dem Deckel eine Dichtung vorgesehen ist. Dadurch wird der technische Vorteil erreicht, dass das Elektronikgehäuse staub- und/oder wasserdicht, z.B. kondenswasser- oder spritzwasserdicht, abgedichtet ist.
According to the invention, the electronics housing has a support rib, wherein the support rib has a minimum distance from the refrigerated goods container in the case of a foamed-up refrigerated goods container. By means of the support rib, the electronics housing can be supported before foaming on the refrigerated goods, especially if, for example, during installation of the refrigerator components are installed in the electronics housing by hand or a backboard is glued to the electronics housing. After foaming, however, the electronics housing, for example arranged in the rear wall section, lifts permanently away from the refrigerated goods container due to the foam pressure. As a result, the technical advantage is achieved that there is no cold bridge between the electronics housing and the refrigerated goods, which could promote the formation of condensation. The support rib extends, for example, like a finger or rod, away from the electronics housing to the outside. It is also possible to provide two or more support ribs. In particular, if the electronics housing is fastened to a side wall of the cooling device with a first electronic housing edge, eg by screws, two support ribs can be provided on a second electronics housing edge opposite the first electronics housing edge.
In a further advantageous embodiment, a power supply unit and / or a control of the refrigeration device are accommodated in the electronics housing. As a result, the technical advantage is achieved that functional components for the operation of the refrigeration device are securely accommodated in the electronics housing.
In a further advantageous embodiment, the power supply and / or the controller are accommodated in a handling housing.
