Description

Die Erfindung betrifft ein Kühlgerät, umfassend ein Gehäuse und ein Kühlaggregat. Im Innenraum des Kühlgeräts kann ein Einbauteil angeordnet sein, das den Innenraum des Kühlgeräts in wenigstens zwei Kühlzonen aufteilt. Ein derartiges Kühlgerät ist beispielsweise aus der FR 1 485 432 A bekannt.The invention relates to a refrigerator, comprising a housing and a cooling unit. In the interior of the refrigerator, a built-in part can be arranged, which divides the interior of the refrigerator into at least two cooling zones. Such a cooling device is for example from the FR 1 485 432 A known.

Herkömmliche Kühlschränke weisen ein isolierendes Gehäuse mit einem für tiefe Temperaturen besonders isolierten und mit einer Klappe oder Türe verschlossenen Abteil auf. Je nach ihrem Anwendungsbereich können Kühlgeräte zusätzlich mit einem Gefrierfach ausgestattet sein, d.h. es werden Geräte mit und ohne Gefrierfach angeboten. In der Regel muss daher bereits bei der Auswahl eines Kühlschranks für einen bestimmten Einsatzzweck die Entscheidung getroffen werden, ob ein Gefrierfach integriert sein soll oder nicht.Conventional refrigerators have an insulating housing with a particularly isolated for low temperatures and closed with a flap or door compartment. Depending on their field of application, refrigerators may additionally be equipped with a freezer, i. There are devices with and without freezer available. As a rule, therefore, when choosing a refrigerator for a particular application, the decision must be made as to whether a freezer should be integrated or not.

Für bestimmte Anwendungsbereiche, beispielsweise bei der Ausstattung von Freizeitfahrzeugen, kann die Frage nach der Notwendigkeit eines Gefrierfachs nicht eindeutig geklärt werden. Ob ein Gefrierfach - auf Kosten des zur Verfügung stehenden Platzes - benötigt wird, wird insbesondere durch die individuellen Wünsche des Verbrauchers bestimmt.For certain applications, for example in the equipment of recreational vehicles, the question of the need for a freezer compartment can not be clarified clearly. Whether a freezer - at the expense of the available space - is needed, is determined in particular by the individual needs of the consumer.

Daher müssen bei der Einrichtung von Freizeitfahrzeugen mehrere Optionen berücksichtigt werden. Insbesondere ist eine Ausstattung mit einheitlichen Kühlgeräten nicht möglich. Zudem muss in der Regel der gesamte Kühlschrank ausgetauscht werden, falls ein Verbraucher ein Kühlgerät mit einer anderen Ausstattung wünscht.Therefore, when setting up recreational vehicles, several options must be considered. In particular, equipping with standard refrigerators is not possible. In addition, as a rule, the entire refrigerator must be replaced if a consumer wants a refrigerator with a different equipment.

Ausgehend davon besteht die Aufgabe der vorliegenden Erfindung darin, ein Kühlgerät bereitzustellen, das flexibel und unter geringem Aufwand mit oder ohne Kühlfach ausgestattet oder entsprechend umgerüstet werden kann.Based on this, the object of the present invention is to provide a cooling device that can be equipped flexibly and with little effort with or without a refrigerated compartment or converted accordingly.

Diese Aufgabe wird gelöst durch ein Kühlgerät gemäß Anspruch 1.This object is achieved by a cooling device according to claim 1.

Das Kühlgerät gemäß Anspruch 1 umfasst ein Gehäuse und ein Kühlaggregat, wobei das Kühlgerät derart angepasst ist, dass der Innenraum des Kühlgeräts durch Einsetzen eines Einbauteils in wenigstens zwei Kühlzonen aufteilbar ist, wobei das Kühlgerät mindestens ein weiteres Kühlaggregat umfasst, wobei jede der wenigstens zwei Kühlzonen wenigstens ein Kühlaggregat aufweist und wobei eine der Kühlzonen als ein separates Gefrierfach bzw. ein Froster ausgebildet ist. Das erfindungsgemäße Kühlgerät zeichnet sich dadurch aus, dass das Einbauteil ein Bodenteil und eine mit dem Bodenteil verbundene Klappe aufweist, wobei die Klappe zum Verschließen des Gefrierfachs bzw. Frosters verschwenkbar mit dem Bodenteil verbunden ist.The cooling device according to claim 1 comprises a housing and a cooling unit, wherein the cooling device is adapted such that the interior of the cooling device is divisible by inserting a fitting in at least two cooling zones, wherein the cooling device comprises at least one further cooling unit, wherein each of the at least two cooling zones has at least one cooling unit and wherein one of the cooling zones is formed as a separate freezer or a freezer. The refrigerator according to the invention is characterized in that the built-in part of a bottom part and a the flap connected to the bottom part, wherein the flap for closing the freezer compartment or freezer is pivotally connected to the bottom part.

Durch das Einsetzen des Einbauteils ist von einem Kühlbereich ein separates Gefrierfach bzw. ein Froster abtrennbar. Die zwei Kühlzonen weisen also unterschiedliche Temperaturen auf. Im als Kühlschrank genutzten Bereich sind dies in der Regel Temperaturen über 0° C, im als Gefrierfach bzw. Froster genutzten Bereich dagegen liegen die Temperaturen unter 0°C.By inserting the built-in part of a cooling area a separate freezer or a freezer can be separated. The two cooling zones therefore have different temperatures. In the area used as a refrigerator, these are generally temperatures above 0 ° C, in the freezer or freezer used area, however, the temperatures are below 0 ° C.

Der Erfindung liegt die Konzeption zugrunde, dass das Kühlgerät ohne Einbauteil bereits möglichst viele Einrichtungen aufweisen soll, die es erlauben, den Innenraum des Kühlgeräts je nach dem Wunsch des Verbrauchers als Kühlschrank ohne Gefrierfach auszuliefern, oder aber in besonders einfacher Weise ein Gefrierfach zu integrieren. Das Einbauteil soll dabei möglichst kostengünstig und einfach einzubauen sein. Außerdem soll das Einbauteil vorzugsweise keine aufwendigen technischen Komponenten, wie z. B. ein Kühlaggregat, einen Lüfter, eine Temperatursteuerung, oder auch Anschlüsse aufweisen. Die erforderlichen technischen Komponenten für die Variante mit Gefrierfach, beispielsweise entsprechende Kühlaggregate, die in den einzelnen Kühlzonen unterschiedliche Kühltemperaturen generieren, sollen bereits im Kühlschrank integriert sein. Außerdem kann beispielsweise die Isolierung des Kühlschrankgehäuses in unterschiedlichen Wandbereichen des Kühlgeräts daran angepasst sein, für welche Temperaturen der angrenzende Innenraum möglicherweise vorgesehen ist. Die Isolierung wird insbesondere in den Wandbereichen des möglichen Gefrierbereichs gegenüber der herkömmlichen Isolierung von Kühlschrankwänden verbessert sein.The invention is based on the concept that the cooling device without built-in part should already have as many devices that allow it to deliver the interior of the refrigerator depending on the desire of the consumer as a refrigerator without freezer, or to integrate a freezer in a particularly simple manner. The built-in part should be as cost-effective and easy to install. In addition, the built-in part is preferably no expensive technical components, such. As a cooling unit, a fan, a temperature control, or even have connections. The required technical components for the variant with freezer compartment, for example corresponding cooling units which generate different cooling temperatures in the individual cooling zones, should already be integrated in the refrigerator. In addition, for example, the insulation of the refrigerator housing in different wall portions of the refrigerator can be adapted to it, for what temperatures the adjacent interior may be provided. The insulation will be improved in particular in the wall areas of the possible freezing area over the conventional insulation of refrigerator walls.

Mit dem beschriebenen Gerät können in einfacher Weise beide Varianten, mit oder ohne Kühlfach, realisiert werden. Ein Nachrüsten kann ebenso kostengünstig und unkompliziert erfolgen, wie ein Umrüsten von der Variante mit Gefrierfach zu der Variante ohne Gefrierfach.With the described device, both variants, with or without a cooling compartment, can be realized in a simple manner. Retrofitting can also be done in a cost-effective and uncomplicated manner, such as converting from the version with freezer compartment to the version without freezer compartment.

Für einen Ausrüster, beispielsweise von Freizeitfahrzeugen, und für den Hersteller der Kühlgeräte erhöht sich mit den erfindungsgemäßen Geräten die Flexibilität in der Produktion und bei der Ausstattung, da im Vorfeld keine Entscheidung getroffen werden muss, in welchen Stückzahlen Kühlschränke mit und ohne Gefrierfach eingesetzt werden. Eine derartige Entscheidung kann auch erst beim Kauf bzw. bei der Einrichtung des Freizeitfahrzeuges getroffen werden. Allerdings soll die Erfindung nicht auf Kühlschränke für Freizeitfahrzeuge beschränkt sein. Vielmehr kann das erfindungsgemäße Kühlgerät für verschiedene Einsatzzwecke geeignet sein.For a supplier, for example of recreational vehicles, and for the manufacturer of refrigerators increases with the devices according to the invention, the flexibility in production and equipment, since no decision must be made in advance in which quantities refrigerators with and without freezer. Such a decision can also be made only when buying or when setting up the recreational vehicle. However, the invention should not be limited to refrigerators for recreational vehicles. Rather, the refrigerator according to the invention may be suitable for different applications.

Insbesondere weist das Gehäuse Führungselemente zum Einschieben und/oder zum Einpassen des Einbauteils in das Gehäuseinnere auf.In particular, the housing has guide elements for insertion and / or for fitting the built-in part into the housing interior.

Das Einbauteil ist vorzugsweise als vormontierte Einheit zum Einschieben in den Innenraum des Kühlschranks ausgebildet.The built-in part is preferably designed as a preassembled unit for insertion into the interior of the refrigerator.

Das Einbauteil kann mit Hilfe der Führungselemente als Ganzes in den Innenraum des Kühlgeräts eingeschoben bzw. aus diesem herausgezogen werden. Neben einer Vereinfachung der Montage lassen sich auf diese Weise auch Fehler beim Einbau vermeiden. Der Ein- oder Umbau kann im Zweifelsfall sogar vom Verbraucher selbst vorgenommen werden. Das Einbauteil kann mit dem Kühlschrank mitgeliefert werden, um dem Verbraucher eine kostengünstige Option für die Ausrüstung mit einem Gefrierfach zu geben. Auf diese Weise wird hohe Flexibilität bei der Entscheidung erreicht, ob ein Gefrierfach integriert werden soll, oder ob der gesamte Innenraum des Kühlgeräts als Kühlschrank genutzt werden soll.The built-in part can be inserted with the aid of the guide elements as a whole in the interior of the refrigerator or pulled out of this. In addition to a simplification of the assembly can be avoided in this way also errors during installation. The installation or conversion can be made in case of doubt even by the consumer himself. The built-in unit can be supplied with the refrigerator to give the consumer a cost-effective option for equipment with a freezer compartment. In this way, high flexibility is achieved in deciding whether a freezer is to be integrated, or whether the entire interior of the refrigerator should be used as a refrigerator.

Insbesondere sind die Führungselemente an der Innenwand des Gehäuses ausgebildet.In particular, the guide elements are formed on the inner wall of the housing.

Die Führungselemente können Vertiefungen und/oder Führungsrillen in den Seitenwänden und/oder der Rückwand des Gehäuses des Kühlgeräts umfassen.The guide elements may comprise recesses and / or guide grooves in the side walls and / or the rear wall of the housing of the refrigerator.

Alternativ oder ergänzend können die Führungselemente auch Vorsprünge an der Gehäuseinnenwand umfassen. Beispielsweise können Leisten zur Auflage des Einbauteils oder Führungsschienen vorgesehen sein.Alternatively or additionally, the guide elements may also comprise projections on the housing inner wall. For example, strips may be provided for supporting the built-in part or guide rails.

Die Führungselemente können zudem eine Vorrichtung zum Fixieren und/oder Verriegeln des eingeschobenen Einbauteils in seiner Einbauposition umfassen. Somit wird nicht nur ein sicherer Halt des Einbauteils gewährleistet, sondern es wird zudem seine Sollposition festgelegt. Auf diese Weise können Fehlpositionierungen und Ungenauigkeiten beim Einbau und damit verbundene Leistungsverluste vermieden werden.The guide elements may also include a device for fixing and / or locking the inserted insert in its installed position. Thus, not only a secure hold of the insert is guaranteed, but it is also set its desired position. In this way, mispositioning and installation inaccuracies and associated power losses can be avoided.

Die Vorrichtung zum Fixieren und/oder Verriegeln des eingeschobenen Einbauteils kann Ausnehmungen und/oder eine Klinke in den Führungselementen zur Fixierung und/oder Arretierung des Einbauteils in den Führungselementen umfassen. Beispielsweise kann eine Vertiefung in einer Führungsrille zum Eingriff einer am Einbauteil angeordneten Klinke vorgesehen sein, oder umgekehrt. Im Rahmen der Erfindung sollen alle dem Fachmann geläufigen Möglichkeiten zur Fixierung des Einbauteils eingeschlossen sein.The device for fixing and / or locking the inserted insert part may comprise recesses and / or a pawl in the guide elements for fixing and / or locking the insert part in the guide elements. For example, a depression may be provided in a guide groove for engagement of a pawl arranged on the fitting, or vice versa. Within the scope of the invention, all possibilities familiar to the person skilled in the art for fixing the built-in component should be included.

Das Bodenteil kann als Zwischenwand zwischen zwei Kühlzonen angeordnet sein.The bottom part can be arranged as an intermediate wall between two cooling zones.

Am äußeren Rand des Bodenteils kann eine Dichtung angeordnet sein, die bei eingesetztem Einbauteil zusammen mit den Gehäusewänden die Kühlzonen gegeneinander abdichtet. Sie kann insbesondere an den Rand des Bodenteils angespritzt sein, beispielsweise im 2-K-Spritzgussverfahren (2-Komponenten-Spritzgußverfahren), und aus einem weicheren Kunststoff hergestellt sein, als das für das Bodenteil verwendete Material.At the outer edge of the bottom part, a seal may be arranged, which seals the cooling zones against each other when the built-in component is inserted together with the housing walls. In particular, it can be molded onto the edge of the bottom part, for example in a 2-component injection molding process (2-component injection molding process), and be made of a softer plastic than the material used for the bottom part.

Das Gehäuse des Kühlgeräts ist gegenüber Wärmeübergang bzw. Wärmedurchtritt isoliert ausgebildet, wobei die Isolierung in unterschiedlichen Wandbereichen bevorzugt an die im Innenraum vorgesehen Kühlzonen angepasst ist. So können die Wände des Gefrierbereichs besser isoliert sein als die Wände, die lediglich den Kühlbereich abgrenzen. Ist beispielsweise die Gefrierzone im oberen Bereich des Gehäuses vorgesehen, so sind der Deckenbereich und die Seitenwände in diesem Bereich des Gehäuses besonders gut isoliert. Der darunter liegende Kühlbereich wird durch Wände mit einer ausreichenden, jedoch preisgünstigeren Isolierung, begrenzt.The housing of the cooling device is formed insulated from heat transfer or heat transfer, wherein the insulation in different wall regions is preferably adapted to the cooling zones provided in the interior. Thus, the walls of the freezing area can be better insulated than the walls, which delimit only the cooling area. If, for example, the freezing zone is provided in the upper area of the housing, then the ceiling area and the side walls are particularly well insulated in this area of the housing. The underlying cooling area is limited by walls with sufficient but less expensive insulation.

Das Kühlaggregat ist derart ausgebildet, dass es in den Kühlzonen unterschiedliche Temperaturen erzeugen kann.The cooling unit is designed such that it can generate different temperatures in the cooling zones.

In this recess 8 can be inserted from the front an intermediate wall. In the embodiment, the recess 8 also extends along the inside of the rear wall of the housing 2. In the region of the lateral guide elements 8, a further vertical recess 9 is provided for locking and fixing an inserted fixture, for example by means of a corresponding pawl arranged on the fixture , serves.

In dem in der Fig. 1 gezeigten Beispiel ist jedoch kein Einbauteil eingesetzt, so dass in diesem Fall der gesamte Innenraum des Kühlgeräts 1 als Kühlschrank mit im Wesentlichen einheitlicher Innentemperatur verwendet werden kann. Auf diese Weise ergibt sich ein geräumiger Kühlraum, während im Bedarfsfall ein Nachrüsten mit einem Gefrierfach möglich ist.In the in the Fig. 1 However, in the example shown, no built-in part is used, so that in this case the entire interior of the refrigerator 1 can be used as a refrigerator with a substantially uniform internal temperature. This results in a spacious refrigerator, while retrofitting with a freezer is possible if necessary.

In Fig. 2 ist das Kühlgerät aus Figur 1 mit einem in das Gehäuse 2 des Kühlgeräts 1 eingesetzten Einbauteil 5 dargestellt. Das Einbauteil 5 bildet dabei ein einheitliches vormontiertes Element, welches zumindest ein Bodenteil 5a und eine Klapptüre 5b umfasst. Die seitlichen Kanten sowie die hintere Kante des Bodenteils 5a sind so ausgebildet und angepasst, das sie in die Vertiefungen 8 eingreifen, wenn das Bauteil 5 in den Innenraums des Gehäuses 2 geschoben wird. Insbesondere kann das Bodenteil 5a einen Verriegelungsmechanismus, beispielsweise eine Klinke, aufweisen. Beim Erreichen der Einbauposition rastet die an der Unterseite des Bodenteils 5a angeordnete Klinke in die vertikale Vertiefung 9 ein, um das Einbauteil 5 in seiner Sollposition zu fixieren.In Fig. 2 is the refrigerator off FIG. 1 shown with a built-in housing 2 of the refrigerator 1 insert 5. The built-in part 5 forms a unitary preassembled element which comprises at least a base part 5a and a hinged door 5b. The side edges and the rear edge of the bottom part 5 a are formed and adapted so that they engage in the recesses 8 when the component 5 is pushed into the interior of the housing 2. In particular, the bottom part 5a may have a locking mechanism, for example a pawl. When reaching the installation position, the pawl arranged on the underside of the bottom part 5a snaps into the vertical recess 9 in order to fix the installation part 5 in its set position.

Das Einbauteil 5 kann insgesamt relativ einfach aufgebaut sein, so dass der Kostenunterschied für ein Kühlgerät mit und ohne Gefrieroption gering ist. Insbesondere brauchen keine aufwendigen technischen Einrichtungen (z.B. Lüfter, Temperatursteuerung) oder Anschlüsse am Einbauteil 5 vorgesehen zu sein. Möglichst alle technischen Voraussetzungen für die Integration eines Gefrierfachs sollen bereits in der Grundversion des Kühlgeräts 1 gemäß Fig. 1 realisiert sein. Das Einbauteil 5 kann daher leicht eingesetzt und unter Umständen mit jedem Kühlgerät als Zusatzteil mitgeliefert werden.The built-in part 5 can be constructed overall relatively simple, so that the cost difference for a refrigerator with and without freezing option is low. In particular, do not need expensive technical facilities (eg fan, temperature control) or connections to the mounting part 5 to be provided. As far as possible all the technical requirements for the integration of a freezer should already in the basic version of the refrigerator 1 according to Fig. 1 be realized. The mounting part 5 can therefore be easily used and may be supplied with each cooling device as an additional part.

An den in die Vertiefungen 8 eingreifenden Kanten des Bodenteils 5a des Einbauteils 5 ist bevorzugt eine Abdichtung, beispielsweise aus einem Elastomer, angeordnet. Die Dichtung kann im 2-K-Spritzgußverfahren an die Ränder des Bodenteils 5a angespritzt werden. Sie ermöglicht eine zuverlässige Trennung und Isolation der Gefrierzone 6 von der Kühlzone 7.At the engaging in the recesses 8 edges of the bottom part 5a of the mounting part 5 is preferably a seal, for example, made of an elastomer disposed. The seal can be injection-molded in 2-K injection molding to the edges of the bottom part 5a. It enables reliable separation and isolation of the freezing zone 6 from the cooling zone 7.

Die Klapptüre 5b des Einbauteils 5 ist mit dem Bodenteil 5a verschwenkbar verbunden.The hinged door 5b of the fitting 5 is pivotally connected to the bottom part 5a.

Durch das Einsetzen des Einbauteils 5 entstehen zwei Kühlzonen 6 und 7, die durch die Elemente 3 und 4 des Kühlaggregats auf unterschiedliche Temperaturen gekühlt werden können. So wird in der vorliegenden Ausführungsform der obere abgrenzte Bereich 6 als Gefrierfach mit Temperaturen beispielsweise unter 0°C genutzt, während der untere abgegrenzte Bereich 7 die Funktion eines Kühlschranks mit Temperaturen über 0°C erfüllt. Die jeweilige Temperatur eines Bereichs 6, 7 kann beispielsweise durch unterschiedliche von den Elementen 3 und 4 erzeugte Kälteleistungen erreicht werden. Außerdem ist es denkbar, zwei separate Kühlaggregate vorzusehen.By inserting the fitting 5, two cooling zones 6 and 7, which can be cooled by the elements 3 and 4 of the cooling unit to different temperatures. Thus, in the present embodiment, the upper bounded area 6 is used as a freezing compartment with temperatures below 0 ° C, for example, while the lower bounded area 7 fulfills the function of a refrigerator with temperatures above 0 ° C. The respective temperature of a region 6, 7 can be achieved, for example, by different cooling capacities generated by the elements 3 and 4. In addition, it is conceivable to provide two separate cooling units.

Die Klapptüre 5b kann im vorliegenden Ausführungsbeispiel von oben her nach unten geklappt werden, um das Gefrierfach zu öffnen. Wie im Zusammenhang mit Fig. 3 deutlich wird, kann die Klapptüre 5b bei geöffnetem Gefrierfach 6 auf einem in der Seitenwand ausgebildeten horizontalen Vorsprung 10 aufliegen und so einen bequemen Zugriff zum Gefrierfach 6 ermöglichen. Im geschlossenen Zustand isoliert die Klapptüre 5b den Gefrierraum 6 gegenüber dem Kühlraum 7.The hinged door 5b can be folded down in the present embodiment from above to open the freezer compartment. As related to Fig. 3 becomes clear, the folding door 5b can rest with the freezer compartment 6 open on a formed in the side wall horizontal projection 10 and thus allow easy access to the freezer compartment 6. When closed, the folding door 5b isolates the freezer compartment 6 with respect to the cooling compartment 7.

Mit dem gezeigten Kühlgerät 1 ist es möglich, je nach dem Wunsch des Verbrauchers, ein Freizeitfahrzeug mit einem Kühlschrank in einfacher Weise um ein Gefrierfach 6 zu erweitern. Ein Umrüsten bzw. Nachrüsten des Kühlgeräts 1 ist einfach und kostengünstig zu bewerkstelligen. Eine Entscheidung, ob ein Kühlgerät 1 mit einem Gefrierfach 6 ausgerüstet werden soll, kann kurzfristig nach individuellen Vorstellungen des Verbrauchers getroffen werden.With the cooling unit 1 shown, it is possible, depending on the desire of the consumer, to expand a recreational vehicle with a refrigerator in a simple manner to a freezer compartment 6. A conversion or retrofitting of the refrigerator 1 is easy and inexpensive to accomplish. A decision as to whether a refrigerator 1 should be equipped with a freezer 6, can be made in the short term according to individual ideas of the consumer.
