Description

Die Erfindung betrifft einen Kühlschrank gemäss dem Oberbegriff des Anspruches 1.The invention relates to a refrigerator according to the preamble of claim 1.

Kühlschränke mit mindestens zwei übereinander angeordneten Kühlfächern, von denen eines als ein Tiefkühlfach dient, sind allgemein bekannt. Ein Kühlschrank dieser Art ist beispielsweise in der CH 695 463 offenbart. Beim diesem Kühlschrank ist jedes der mit verschiedenen Temperaturen betriebenen Kühlfächer mit einem entsprechenden Verdampfer versehen, der einen Teil eines mit einem Kompressor und einem Kondensator ausgestatteten Kühlkreislaufes bildet.Refrigerators with at least two superposed cooling compartments, one of which serves as a freezer, are well known. A refrigerator of this kind is for example in the CH 695 463 disclosed. In this refrigerator, each of the refrigerated compartments operated at different temperatures is provided with a corresponding evaporator forming part of a refrigeration circuit equipped with a compressor and a condenser.

Der vorliegenden Erfindung wurde die Aufgabe zugrundegelegt, den Kühlschrank der eingangs genannten Art als einen sogenannten No-Frost-Kühlschrank zu gestalten.The present invention has been based on the task to make the refrigerator of the type mentioned as a so-called no-frost refrigerator.

Die Aufgabe wird erfindungsgemäss durch einen Kühlschrank mit den Merkmalen des Anspruches 1 gelöst.The object is achieved by a refrigerator with the features of claim 1.

Weitere bevorzugte Ausgestaltungen des erfindungsgemässen Kühlschrankes bilden den Gegenstand der abhängigen Ansprüche.Further preferred embodiments of the inventive refrigerator form the subject of the dependent claims.

Beim erfindungsgemässen Kühlschrank werden die Kühlfächer mittels einer über einen gemeinsamen Verdampfer anhand eines Ventilators umgewälzten Kühlluft gekühlt. Der Verdampfer ist in einer separaten Verdampferkammer untergebracht.In the refrigerator according to the invention, the cooling compartments are cooled by means of a cooling air circulated via a common evaporator by means of a fan. The evaporator is housed in a separate evaporator chamber.

Dadurch, dass zum Abtauen des Verdampfers die Verbindungswege zwischen der Verdampferkammer und den einzelnen Kühlfächern verschlossen werden können und die Luft in Verdampferkammer allein zirkuliert, kann der Abtauvorgang schnell durchgeführt werden, insbesondere wenn die Luft in der Verdampferkammer vorübergehend erwärmt wird.Characterized in that for defrosting the evaporator, the communication paths between the evaporator chamber and the individual cooling compartments can be closed and the air circulates in the evaporator chamber alone, the defrosting process can be performed quickly, especially when the air in the evaporator chamber is temporarily heated.

Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen rein schematisch:

The invention will be explained in more detail with reference to the drawing. It shows purely schematically:
Fig.1
an embodiment of an inventive refrigerator from the front in section;
Fig. 2
the fridge after Fig. 1 in a cut.

In Fig.1 und Fig.2 werden ein Kühlschrank 1 mit zwei übereinander angeordneten Kühlfächern 2, 3 gezeigt, von denen das untere als ein Tiefkühlfach 2 dient. Die Kühlfächer 2, 3 sind jeweils mit einer Tür 2a, 3a verschliessbar. An der Rückwand 4 des Tiefkühlfaches 2 grenzt eine separate Verdampferkammer 5 an, in der ein Verdampfer 10 im wesentlichen aufrecht angeordnet ist. Der Verdampfer 10 bildet einen Teil eines mit einem Kompressor und einem Kondensator ausgestatteten Kühlkreislaufes, die nicht näher gezeigt sind.In Fig.1 and Fig.2 a refrigerator 1 with two superposed cooling compartments 2, 3 are shown, of which the lower serves as a freezer compartment 2. The cooling compartments 2, 3 are each provided with a door 2a, 3a closable. On the rear wall 4 of the freezer compartment 2 adjoins a separate evaporator chamber 5, in which an evaporator 10 is arranged substantially upright. The evaporator 10 forms part of a equipped with a compressor and a condenser cooling circuit, which are not shown in detail.

Die für die Kühlung vorgesehene Luft wird von oben in die Verdampferkammer 5 geführt. Sie strömt folglich durch einen Aussenteil 5a der Verdampferkammer 5 nach unten und dann von unten durch den Verdampfer 10 hindurch.The intended for the cooling air is fed from above into the evaporator chamber 5. It thus flows through an outer part 5a of the evaporator chamber 5 down and then from below through the evaporator 10 therethrough.

Im oberen Bereich einer die Verdampferkammer 5 vom Tiefkühlfach 2 vorhandenen Trennwand 11 ist eine Anzahl von Eintrittsöffnungen 12 vorgesehen, über welche die Kühlluft in das Tiefkühlfach 2 eingeleitet wird, wobei die mit Hilfe eines nicht näher dargestellten Ventilators im Tiefkühlfach 2 zirkulierende Kühlluft wiederum über eine Anzahl von im unteren Bereich der Trennwand 11 vorgesehenen Austrittsöffnungen 13 von unten in den Verdampfer 10 gelangt. Die Temperatur im Tiefkühlfach 2 wird gemessen und derart geregelt, dass beim Erreichen eines Sollwertes die Eintrittsöffnungen 12 verschlossen werden, vorzugsweise mit Hilfe eines angedeuteten steuerbaren Schiebers 14.In the upper part of a the evaporator chamber 5 from the freezer compartment 2 existing partition wall 11, a number of inlet openings 12 is provided, via which the cooling air is introduced into the freezer compartment 2, wherein the circulating with the aid of a fan not shown in the freezer compartment 2 cooling air in turn over a number supplied from the bottom of the partition wall 11 outlet openings 13 from below into the evaporator 10. The temperature in the freezer compartment 2 is measured and regulated so that the inlet openings 12 are closed when a setpoint value is reached, preferably with the aid of an indicated controllable slide 14.

In einer oberen Wand 15 der Verdampferkammer 5 ist einerseits eine Anzahl von Anschlussöffnungen 18 vorgesehen, die zum oberen Kühlfach 3 führen, und anderseits eine Anzahl von Rückführöffnungen 17 für die im oberen Kühlfach 3 zirkulierende Kühlluft vorhanden. Auch diese Anschluss- und Rückführöffnungen 18, 17 sind vorzugsweise mittels eines Schiebers verschliessbar.In an upper wall 15 of the evaporator chamber 5, on the one hand, a number of connection openings 18 are provided which lead to the upper cooling compartment 3, and on the other hand a number of return openings 17 for the circulating in the upper cooling compartment 3 cooling air available. These connection and return openings 18, 17 are preferably closed by means of a slider.

Bei Kühlschränken mit mehren Kühlfächern würde man zweckmässigerweise für jedes oberhalb des Tiefkühlfaches 2 vorgesehene Kühlfach entsprechende Anschluss- und Rückführöffnungen vorsehen.In refrigerators with multiple refrigerators would conveniently provide appropriate connection and return openings for each provided above the freezer compartment 2 cooling compartment.

Zum Abtauen des Verdampfers 10, das periodisch, beispielsweise jeweils nach 7 Stunden Kompressor-Arbeit oder alle 24 Stunden durchgeführt wird, werden die Verbindungswege zwischen der Verdampferkammer 5 und dem Tiefkühl- 2 als auch dem Kühlfach 3 (bei mehr als zwei Kühlfächern zu allen Kühlfächern) verschlossen, Die Eintrittsöffnungen 12 und die Austrittsöffnungen 13 beim Tiefkühlfach 2 werden mit Hilfe von Schiebern 14, 16 geschlossen, so dass in diesem keine Luftzirkulation stattfindet, und auch die Luftzirkulation im oberen Kühlfach 3 wird unterbunden. Die Anschlussöffnungen 18 zum oberen Kühlfach 3 (bzw. zum jeweiligen Kühlfach) werden durch eine Verbindungsleitung 20 an die Rückführöffnungen 17 angeschlossen und die Luftzirkulation beschränkt sich damit innerhalb der Verdampferkammer 5, bei dem die Luft durch den Aussenteil 5a nach unten, durch den Verdampfer 10 hindurch nach oben und über die Verbindungsleitung 20 wieder von oben in den Aussenteil 5a strömt. Zu diesem Zwecke sind in den Anschluss- bzw. Rückführöffnungen 18, 17 ansteuerbare Schliessorgane 18', 17', wie zum Beispiel Schieber, enthalten, welche die gewünschte Luftzirkulation bewirken.For defrosting the evaporator 10, which is carried out periodically, for example after 7 hours of compressor work or every 24 hours, the communication paths between the evaporator chamber 5 and the freezer 2 and the cooling compartment 3 (with more than two refrigerators to all refrigerators ), the inlet openings 12 and the outlet openings 13 in the freezer compartment 2 are closed by means of slides 14, 16, so that in this no air circulation takes place, and also the circulation of air in the upper compartment 3 is suppressed. The connection openings 18 to the upper cooling compartment 3 (or to the respective cooling compartment) are connected by a connecting line 20 to the return openings 17 and the air circulation is thus limited within the evaporator chamber 5, in which the air through the outer part 5a down, through the evaporator 10th through to the top and via the connecting line 20 again flows from above into the outer part 5a. For this purpose, in the connection or return openings 18, 17 controllable closing members 18 ', 17', such as slides, containing, which cause the desired air circulation.

Dadurch ist ein schnelles Abtauen des Verdampfers gewährleistet, insbesondere wenn die Luft in der Verdampferkammer 5 vorübergehend erwärmt wird, vorzugsweise durch eine im unteren Teil des Verdampfers 10 plazierten Heizschlange 19.This ensures rapid defrosting of the evaporator, in particular if the air in the evaporator chamber 5 is temporarily heated, preferably by a heating coil 19 placed in the lower part of the evaporator 10.

Die Erfindung ist mit dem obigen Ausführungsbeispiel ausreichend dargetan. Sie könnte aber noch in anderen Varianten veranschaulicht sein.The invention is sufficiently demonstrated with the above embodiment. But it could still be illustrated in other variants.

So ist die Anordnung der Verdampferkammer 5 an der Rückwand 4 des Tiefkühlfaches 2 nicht zwingend notwendig; sie könnte auch an einer Seitenwand desselben angrenzen oder gar einer der Wände des oberen Kühlfaches 3 zugeordnet sein. Die dargestellte Lösung ermöglicht jedoch eine besonders vorteilhafte Luftführung.Thus, the arrangement of the evaporator chamber 5 on the rear wall 4 of the freezer compartment 2 is not absolutely necessary; it could also be adjacent to one of its side walls or even to one of the walls of the upper one Refrigerator compartment 3 be assigned. However, the solution shown allows a particularly advantageous air flow.

Auch die Mittel zum Verschliessen und Öffnen von Verbindungswegen zwischen der Verdampferkammer 5 und den einzelnen Kühlfächern könnten anders als Schieber, z.B. als Klappen oder dergleichen, ausgebildet sein.Also, the means for closing and opening communication paths between the evaporator chamber 5 and the individual refrigerators may be different than slides, e.g. be designed as flaps or the like.
