Description

Die Erfindung betrifft einen Kühlschrank gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a refrigerator according to the preamble of the first claim.

Bei einem bekannten Kühlgerät dieser Art (DE-GM 77 31 752) ist unterhalb eines mit einer Klappe verschlossenen Tiefkühlfaches ein Hauptkühlfach vorgesehen, in dem Waren bei einer Temperatur von beispielsweise 0°C bis 5°C gelagert werden. Unterhalb des Hauptkühlfaches befindet sich ein Zusatzkühlfach, das gegenüber dem Hauptkühlfach durch eine waagrechte Trennwand abgeteilt ist. Das Zusatzkühlfach unterhalb des Hauptkühlfaches dient dabei ebenso wie andere Zusatzkühlfächer an der Türe zur Lagerung von Waren bei Temperaturen oberhalb von 5°C. Durch die unmittelbare Verbindung dieser Zusatzkühlfächer mit dem Hauptkühlfach ist jedoch eine optimale Temperatur für die dort zu lagernden Güter nicht zu erreichen. Dadurch werden in der Regel Getränke und empfindliche Südfrüchte im allgemeinen zu stark gekühlt.In a known refrigerator of this type (DE-GM 77 31 752), a main refrigerator compartment is provided below a freezer compartment closed with a flap, in which goods are stored at a temperature of, for example, 0 ° C. to 5 ° C. There is an additional cooling compartment below the main cooling compartment, which is separated from the main cooling compartment by a horizontal partition. The additional cooling compartment below the main cooling compartment serves as well as other additional cooling compartments on the door for storing goods at temperatures above 5 ° C. Due to the direct connection of these additional cooling compartments with the main cooling compartment, an optimal temperature for the goods to be stored there cannot be reached. As a result, drinks and sensitive tropical fruits are generally cooled too much.

Aufgabe der Erfindung ist es, bei einem Kühlschrank gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch die mit einfachen Mitteln eine Abgrenzung zwischen den Kühlfächern und im praktischen Betrieb eine Einsparung von Kühlenergie erreicht wird.The object of the invention is to take measures in a refrigerator according to the preamble of the first claim, by means of which simple means a delimitation between the cooling compartments and a saving of cooling energy is achieved in practical operation.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Durch die erfindungsgemäße Ausgestaltung wird nun der für die Kühlung von Waren im Temperaturbereich von etwa 0°C bis plus 5°C vorgesehene Raum auf das Hauptkühlfach beschränkt, während der Zusatzkühlraum zur Aufbewahrung von Butter, Getränken, Gemüse u. dergl. jetzt im Temperaturbereich von 5°C bis 15°C betrieben werden kann. Dabei entweicht bei dem im praktischen Betrieb unvermeidbaren öffnen der Tür zunächst lediglich Kälte aus dem Zusatzkühlfach, wenn nur Waren daraus entnommen werden. In diesem Fall tritt im Gegensatz zu bisherigen Ausführungen keine Kälteenergie aus dem Hauptkühlfach aus.The configuration according to the invention now limits the space provided for the cooling of goods in the temperature range from approximately 0 ° C. to plus 5 ° C. to the main cooling compartment, while the additional cooling space for storing butter, drinks, vegetables and the like. can now be operated in the temperature range from 5 ° C to 15 ° C. When opening the door, which is unavoidable in practical operation, only the cold escapes from the additional cooling compartment if only goods are removed from it. In this case, in contrast to previous versions, no cooling energy emerges from the main refrigerator compartment.

Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen angegeben.Advantageous embodiments of the invention are specified in the further claims.

Die Erfindung ist nachfolgend anhand der Zeichnung -eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to the drawing of an exemplary embodiment.

In einem Gehäuse 1 eines Kühlschrankes befindet sich im oberen Bereich ein Tiefkühlfach 2, das mit einer schwenkbaren Verschlußplatte 10 verschlossen ist. Unterhalb des Tiefkühlfaches 2 befindet sich ein Normalkühlfach 3, das für Lebensmittel mit einer günstigeren Lagertemperatur von etwa 0°C bis plus 5°C bestimmt ist. Die Zugrifföffnung zum Hauptkühlfach 3 ist durch eine Klappe 4 verschlossen, die um eine senkrechte Achse schwenkbar am Gehäuse 1 gelagert ist. In einer parallelen Ebene zur Klappe 4 verläuft eine den gesamten Kühlraum verschließende Außentür 5, in der offene Zusatzkühlfächer 6 für die Lagerung von Butter, Eiern, Getränken und dergl. vorgesehen sind. Ein weiteres Zusatzkühlfach 6 ist im Bereich einer Gemüseschale 7 vorgesehen, die durch eine waagrechte Trennwand 8 vom Hauptkühlfach 3 abgeteilt ist. Nachdem die Klappe 4 von den Zusatzkühlfächern 6 in der Tür mit Abstand angeordnet ist, ist ein Wärmeaustausch im Bereich der Zusatzkühlfächer 6 möglich. Damit hierbei eine ausreichend niedrige Temperatur im Bereich der Zusatzkühlfächer aufrechterhalten werden kann, ist jeweils wenigstens ein Durchbruch 9 im oberen Bereich der Klappe 4 bzw. in der Trennwand 8 vorgesehen. Der Querschnitt dieser Durchbrüche kann veränderbar ausgebildet sein, um den Kältefluß ggf. thermostatisch regulieren zu können. Die Klappe 4 besteht im übrigen vorzugsweise aus durchsichtigem Material, so daß bei geöffneter Außentür und eingeschalteter Innenbeleuchtung bei geschlossener Klappe 4 eine dem Zugriff immer vorausgehende Betrachtung des Kühlgutes möglich ist. Bis zum Zugriff, dem die Öffnung der Klappe 4 vorausgeht, ist somit der Kälteverlust aus dem Hauptkühlfach 3 verhindert. Um den Kälteverlust dabei so gering wie möglich zu halten, kann der Tür ein federelastisches Element zugeordnet sein, das die Klappe 4 selbsttätig in die Schließstellung bringt.In a housing 1 of a refrigerator there is a freezer compartment 2 in the upper area, which is closed with a pivotable closure plate 10. Below the freezer compartment 2 is a normal refrigerator compartment 3, which is intended for food with a more favorable storage temperature of about 0 ° C to plus 5 ° C. The access opening to the main refrigerator compartment 3 is closed by a flap 4 which can be pivoted about a vertical axis on the housing 1 is stored. In a parallel plane to the flap 4 there is an outer door 5 which closes the entire cooling space and in which open additional cooling compartments 6 are provided for the storage of butter, eggs, drinks and the like. A further additional cooling compartment 6 is provided in the area of a vegetable dish 7, which is separated from the main cooling compartment 3 by a horizontal partition 8. After the flap 4 is arranged at a distance from the additional cooling compartments 6 in the door, heat exchange in the region of the additional cooling compartments 6 is possible. So that a sufficiently low temperature can be maintained in the area of the additional cooling compartments, at least one opening 9 is provided in the upper area of the flap 4 or in the partition 8. The cross section of these breakthroughs can be designed to be variable so that the cold flow can be thermostatically regulated if necessary. The flap 4 is, moreover, preferably made of transparent material, so that when the outer door is open and the interior lighting is switched on when the flap 4 is closed, the refrigerated goods can always be viewed before access. Until the access, which is preceded by the opening of the flap 4, the loss of cold from the main cooling compartment 3 is thus prevented. In order to keep the loss of cold as low as possible, the door can be assigned a spring-elastic element which automatically brings the flap 4 into the closed position.
