Die Erfindung betrifft einen Kühlschrank mit mehreren übereinander liegenden Kühlzonen, mit einem Tiefkühlfach und einem oberhalb diesem angeordneten Sonderfach.The invention relates to a refrigerator with several superimposed Cooling zones, with a freezer compartment and one arranged above it Special subject.

Derartige Kühlschränke dienen im Haushalt dazu, Lebensmittel bei unterschiedlichen Temperaturen aufzubewahren. In einem Tiefkühlfach werden gefrorene Lebensmittel gelagert, ein darüber befindliches Sonderfach mit einer Temperatur von etwa 0°C dient zur Aufnahme von Fisch, Fleisch, Gemüse - wie Gurken, Früchte od. dgl. - und ein drittes oberstes Kühlfach mit etwa 5°C bis 11°C dient für die gekühlte Aufbewahrung von Getränken und anderen Lebensmitteln.Such refrigerators are used in the household to keep food at different Store temperatures. Be in a freezer frozen food stored, a special compartment above with a temperature of around 0 ° C is used to ingest fish, meat, Vegetables - such as cucumbers, fruits or the like - and a third top cooling compartment with around 5 ° C to 11 ° C is used for the refrigerated storage of beverages and other foods.

Mit der Erfindung soll die Aufgabe gelöst werden, einen Kühlschrank mit geringerem Aufwand und vermindertem Energieverbrauch zu schaffen. The object of the invention is to achieve a refrigerator to create less effort and reduced energy consumption.

Ferner soll eine mit einfachen Mitteln erreichbare genaue Temperatur insbesondere auch im Sonderfach erzielt werden.Furthermore, an accurate temperature that can be achieved with simple means should in particular can also be achieved in a special subject.

Die Erfindung, mit der diese Aufgabe gelöst wird, ergibt sich dadurch, dass zwischen dem Tiefkühlfach und dem darüber angeordneten Sonderfach Luftzirkulationsmittel vorhanden sind zur Kühlung des Sonderfaches durch Kaltluftübertragung.The invention with which this object is achieved results from that between the freezer compartment and the special compartment arranged above it Air circulation means are available for cooling the special compartment through cold air transmission.

Dadurch wird erreicht, dass in dem über dem Tiefkühlfach befindlichen Sonderfach auf einen sonst üblichen Verdampfer verzichtet werden kann, da die Kühlung nur durch Kaltluftübertragung erfolgt. Ein weiterer Vorteil besteht darin, dass die aus dem Tiefkühlfach bezogene Kühlluft trocken ist, sodass eine Eisbildung und damit das Abtauen weitgehend entfällt.This ensures that the one located above the freezer compartment Special compartment can be dispensed with an otherwise usual evaporator, since the cooling is done only by cold air transmission. Another advantage is that the cooling air drawn from the freezer compartment is dry so that ice formation and defrosting are largely eliminated.

Fig. 1 zeigt in schematischer Darstellung ein Kühlaggregat eines Kühlschrankes 1 mit einer an sich bei Haushaltkühlschränken üblichen Bauart. Fig. 1 shows a schematic representation of a refrigerator cooling unit 1 with a design that is customary in household refrigerators.

Der Kühlschrank enthält drei Kühlzonen A, B, C, in denen unterschiedliche Temperaturen aufrecht erhalten werden. Das unterste Kühlfach A ist als Tiefkühlfach mit einer Temperatur von etwa -18°C (bis -24°C) ausgeführt. Das benachbarte, darüber liegende mittlere Sonderfach B ist für eine Temperatur von etwa 0°C (bis +5°C) ausgelegt und das oberste Kühlfach C wird bei einer Temperatur von über +5°C (bis +11°C) betrieben.The refrigerator contains three cooling zones A, B, C, in which different Temperatures are maintained. The lowest cooling compartment A is designed as a freezer compartment with a temperature of around -18 ° C (to -24 ° C). The adjacent middle special compartment B above is for one Temperature of about 0 ° C (to + 5 ° C) and the top cooling compartment C is operated at a temperature above + 5 ° C (up to + 11 ° C).

Das Kühlaggregat enthält einen konventionellen Kompressor 6, von dem Kühlmitteldampf über eine Leitung 8 aus den Verdampfern 10, 12 angesaugt und auf Sättigungsdruck komprimiert wird. In einem Kondensator 14 wird der Dampf unter Entziehung von Wärme verflüssigt, dann über eine dem Tiefkühler zugeordnete Rahmenheizung 16 durch Leitungen 18, 32 den Verdampfern 10, 12 zugeleitet, wobei der Verdampfer 12 im Kühlfach C mit Kühlmittelleitungen 32 mit dem Tiefkühlfach A verbunden ist.The cooling unit contains a conventional compressor 6, of which Coolant vapor is drawn in from the evaporators 10, 12 via a line 8 and is compressed to saturation pressure. In a capacitor 14 if the steam is liquefied while removing heat, then via a the frame heater 16 associated with the freezer through lines 18, 32 fed to the evaporators 10, 12, the evaporator 12 in the refrigerator compartment C is connected to the freezer compartment A by means of coolant lines 32.

Erfindungsgemäss erfolgt die Kühlung des mittleren Sonderfaches B nur durch einen aus dem Tiefkühlfach A abgezogenen Kühlluftstrom, hierzu zwischen dem Tiefkühlfach A und dem darüber angeordneten Sonderfach B Luftzirkulationsmittel zur Kühlung des Sonderfaches B vorhanden sind.According to the invention, the central special compartment B is only cooled through a cooling air flow extracted from the freezer compartment A, for this purpose between freezer compartment A and the special compartment arranged above it B Air circulation means for cooling the special compartment B are available.

Die Luftzirkulationsmittel sind derart ausgestaltet, dass eine erste Luftzirkulation vom Tiefkühlfach A zu einem Wärmetauscher 20 und eine zweite, von der ersten getrennte Luftzirkulation im Sonderfach B vorgesehen ist, die ebenfalls mit dem Wärmetauscher 20 zusammenwirkt.The air circulation means are designed such that a first air circulation from freezer compartment A to a heat exchanger 20 and a second one, is provided in the special compartment B from the first separate air circulation, which also interacts with the heat exchanger 20.

Wie aus Fig.2 und Fig.3 hervorgeht, ist für die erste Luftzirkulation ein sich bei der Rückwand des Kühlschrankes 1, hinter dem Tiefkühlfach A und dem Sonderfach B befindlicher Luftführungskanal 25 angeordnet. As can be seen from Fig. 2 and Fig. 3, is for the first air circulation the rear wall of the refrigerator 1, behind the freezer compartment A and the special compartment B located air duct 25.

Durch diesen Luftführungskanal 25 wird mittels eines ersten, im Bereich des Tiefkühlfaches A angeordneten Ventilator 26 Kühlluft aus diesem Fach A zum Wärmetauscher 20 beim Sonderfach B und zurück in das Tiefkühlfach A geleitet wird. Der Luftführungskanal 25 weist dementsprechend einerseits einen vom Ventilator 26 ausgehenden Ansaugstutzen 24, ein mit den Lamellen 21 des Wärmetauschers 20 enthaltendes horizontales Stück und einen Rückführungsstutzen 28 auf.Through this air duct 25 is by means of a first, in the area of the freezer compartment A arranged fan 26 cooling air from this Compartment A to heat exchanger 20 at special compartment B and back into that Freezer compartment A is directed. The air duct 25 points accordingly on the one hand an intake port 24 emanating from the fan 26, a horizontal containing the fins 21 of the heat exchanger 20 Piece and a return pipe 28 on.

Der bei der Rückwand des Sonderfaches B angeordnete Wärmetauscher 20 besteht aus mehreren im Luftführungskanal 25 befindlichen horizontalen Lamellen 21, einer Zwischenwand 23 und aus sich in das Sonderfach B erstreckenden vertikalen Lamellen 22. Die horizontalen Lamellen 21 nehmen die Kälte der an diesen zirkulierenden Kaltluft auf, wobei sie mit der annähernd minus 18°C kalten Luft beaufschlagt und entsprechend gekühlt werden. Die Zwischenwand 23 dient für die Übertragung der erzeugten Kälte der Lamellen 21 des Kanales auf die Lamellen 22 im Sonderfach B. Zweckmässigerweise ist der Wärmetauscher 20 aus einem gut leitenden Material hergestellt, bspw. aus einem Aluminium-Druckguss.The heat exchanger 20 arranged at the rear wall of the special compartment B. consists of several horizontal in the air duct 25 Slats 21, an intermediate wall 23 and of itself in the special compartment B vertical slats 22. Take the horizontal slats 21 the coldness of the cold air circulating on these, with the air at approximately minus 18 ° C and cooled accordingly become. The intermediate wall 23 is used for the transmission of the generated Cold of the slats 21 of the channel on the slats 22 in special compartment B. The heat exchanger 20 is expediently made of a highly conductive material Material made, for example, from an aluminum die-cast.

Für die zweite Luftzirkulation im Sonderfach B zur Erzeugung der gewünschten Temperatur, die vorzugsweise 0° oder etwas höher liegt, ist innenseitig der Rückwand 37 dieses Sonderfaches B ein separater Luftführungskanal 35 gebildet, der durch eine annähernd parallel zur Rückwand 37 angeordnete Blende 36 begrenzt ist. Innerhalb dieses Luftführungskanales 35 sind ein von einem Motor 34 angetriebener Ventilator 30 und unterhalb diesem die sich vertikal erstreckenden Lamellen 22 angeordnet. Am oberen und unteren Ende dieses Kanales 35 sind Öffnungen 38 vorgesehen, durch diese die Luft aus dem Sonderfach B angesaugt und in abgekühltem Zustand wieder zurück in diesen Kühlfachraum geleitet wird.For the second air circulation in special compartment B to generate the desired one Temperature, which is preferably 0 ° or slightly higher, is on the inside the rear wall 37 of this special compartment B is a separate air duct 35 formed by an approximately parallel to the rear wall 37 arranged aperture 36 is limited. Within this air duct 35 are a fan 30 driven by a motor 34 and below this arranged the vertically extending slats 22. Openings 38 are provided at the upper and lower ends of this channel 35, through this the air is sucked out of special compartment B and cooled Condition is directed back into this refrigerator compartment.

Die elektrische Steuerung und Anzeige erfolgt zentral von einem Steuertableau 34 aus. Von diesem gehen Leitungen 36 zu den Ventilatoren 26, 30, Leitungen 44, 46 zu den Temperatur-Fühlern 38, 39 in den Kühlräumen B, C und eine Leitung 48 zum Kompressor 6. Eine weitere, nicht eingezeichnete Leitung könnte auch zu einem Fühler im Tiefkühlfach A führen.The electrical control and display takes place centrally from a control panel 34 out. From this lines 36 go to the fans 26, 30, Lines 44, 46 to the temperature sensors 38, 39 in the cold rooms B, C and a line 48 to the compressor 6. Another, not shown Cable could also lead to a sensor in freezer compartment A.

Eine Ausführungsvariante besteht gemäss Fig.4 darin, dass in der Kühlmittel-Leitung anschliessend an die Rahmenheizung 16 ein Ventil 40 eingebaut wird, welches eine Kühlmittelleitung 42 direkt mit dem Verdampfer 12 des Kühlfaches C verbindet. Dies ermöglicht einen "Sparbetrieb", wenn der Kühlschrank beispielsweise in einem nicht ständig benutzten Ferienhaus installiert ist.An embodiment variant according to Figure 4 is that in the coolant line then a valve 40 is installed on the frame heater 16 which is a coolant line 42 directly to the evaporator 12 of the refrigerator compartment C connects. This enables "economy mode", for example, if the refrigerator is in a holiday home that is not used all the time is installed.

Die Erfindung ist mit diesen Ausführungsbeispielen ausreichend dargetan. Sie könnte noch in anderen Varianten veranschaulicht sein. So könnte im Prinzip der Kühlschrank auch nur aus zwei Kühlfächern bestehen. Selbstverständlich könnten auch die Lamellen je nach Positionierung des Wärmetauschers anders als dargestellt ausgeführt sein.The invention is sufficiently demonstrated with these exemplary embodiments. It could be illustrated in other variants. So in Principle of the refrigerator also consist of only two cooling compartments. Of course could also be the fins depending on the position of the heat exchanger be executed differently than shown.
