Description

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem ersten und einem zweiten Bereich im Innenraum des Kühl- und/oder Gefriergeräts. Ein Kühl- und/oder Gefriergerät gemäß dem Oberbegriff von Anspruch 1 wird in WO2005/003659 offenbart. Bekannte Kühlgeräte weisen für die Kühlung von im Innenraum befindlichen voneinander abgetrennten Bereichen einen Ventilator und mehrere Luftführungskanäle sowie Klappen auf, um die Temperatur in den jeweiligen Bereichen einzustellen. Dadurch wird es möglich, im Innenraum eines Kühlgerätes mehrere Temperaturzonen zu erhalten, so dass den unterschiedlichen Kühlbedürfnissen des in das Gerät einzulagernden Kühlguts besser Rechnung getragen werden kann. Der Ventilator befindet sich dabei zumeist im hinteren, oberen Bereich eines Kühlluftkanals und bläst die aus dem Innenraum des Kühlgeräts kommende Luft über einen Verdampfer, so dass diese Luft wieder abkühlt wird. Die derart abgekühlte Luft wird sodann über Öffnungen in die jeweiligen Bereiche bzw. Fächer oder Temperaturzonen geleitet.The present invention relates to a refrigerator and / or freezer with at least a first and a second region in the interior of the refrigerator and / or freezer. A refrigerator and / or freezer according to the preamble of claim 1 is in WO2005 / 003659 disclosed. Known refrigerators have for the cooling of areas located in the interior separated areas a fan and a plurality of air ducts and flaps to adjust the temperature in the respective areas. This makes it possible to obtain a plurality of temperature zones in the interior of a refrigerator, so that better account can be taken of the different cooling requirements of the refrigerated goods to be stored in the appliance. The fan is usually located in the rear, upper region of a cooling air duct and blows the air coming from the interior of the refrigerator via an evaporator, so that this air is cooled again. The thus cooled air is then passed through openings in the respective areas or compartments or temperature zones.

Diese Art der Regelung der Temperatur der einzelnen Kühlzonen in einem Kühlgerät kann jedoch nicht verhindern, dass es zu leichten Temperaturschwankungen in den einzelnen Temperaturzonen kommt. Daher wäre insbesondere eine zielgerichtete und schnellere Einstellung bzw. Einregelung z.B. auf einen konstanten Wert der Temperatur wünschenswert.However, this type of regulation of the temperature of the individual cooling zones in a cooling device can not prevent slight temperature fluctuations occurring in the individual temperature zones. Therefore, in particular, a more targeted and faster adjustment, e.g. desirable to a constant value of the temperature.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kühl- und/oder Gefriergerät der eingangs genannten Art in vorteilhafter Weise weiterzubilden, insbesondere dahingehend, dass eine sehr genaue und zielgerichtete Temperaturregelung pro Kühlbereich ermöglicht wird.It is therefore the object of the present invention to develop a refrigerator and / or freezer of the type mentioned in an advantageous manner, in particular to the effect that a very accurate and targeted temperature control per cooling area is made possible.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1. Danach ist vorgesehen, dass ein Kühl- und/oder Gefriergerät wenigstens einen ersten und einem zweiten Bereich im Innenraum des Kühl- und/oder Gefriergeräts aufweist. Weiter sind mehrere Luftumwälzmittel vorgesehen, wobei jeweils wenigstens ein Luftumwälzmittel einem Bereich zugeordnet ist. Dadurch ergibt sich der Vorteil, dass beispielsweise die Zuführung von gekühlter Luft zu einem Bereich und damit auch die Temperatur in diesem Bereich genau eingestellt werden. Insbesondere wird dies durch dynamische Luftumwälzmittel ermöglicht, die es beispielsweise erlauben, den dem Bereich zuzuführenden Kühlluftstrom zu variieren. Bei dem Innenraum handelt es sich vorzugsweise um den Innenraum des Kühlteils des Kühl- und/oder Gefriergerätes. Grundsätzlich ist denkbar, dass das Gerät noch zusätzlich ein Gefrierteil mit einem vom Innenraum des Kühlteils abgesonderten Innenraum aufweist.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that a refrigerator and / or freezer has at least a first and a second region in the interior of the refrigerator and / or freezer. Furthermore, a plurality of air circulation means are provided, wherein in each case at least one air circulation means is assigned to one area. This results in the advantage that, for example, the supply of cooled air to a range and thus the temperature in this area are set accurately. In particular, this is made possible by dynamic air circulation means which allow, for example, to vary the cooling air flow to be supplied to the area. The interior is preferably the interior of the cooling part of the refrigerator and / or freezer. In principle, it is conceivable that the device additionally has a freezer compartment with an interior separated from the interior of the refrigerator compartment.

Es ist weiter denkbar, dass der Bereich eine eigenständige Temperaturzone ist und/oder dass die Bereiche voneinander unterschiedliche Temperaturen aufweisen. So kann beispielsweise der erste Bereich eine Temperatur von ca. 4°C aufweisen und ein zweiter Bereich eine Temperatur von ca. 8°C aufweisen. Denkbar ist vorteilhafter Weise, dass die Bereiche Temperaturen zwischen -3°C bis +8°C aufweisen. Die jeweiligen Temperaturen in den einzelnen Bereichen können identisch oder teilweise identisch sein, aber auch vollkommen unterschiedlich gewählt werden.It is also conceivable that the region is an independent temperature zone and / or that the regions have mutually different temperatures. For example, the first region may have a temperature of approximately 4 ° C. and a second region may have a temperature of approximately 8 ° C. It is conceivable advantageously that the ranges have temperatures between -3 ° C to + 8 ° C. The respective temperatures in the individual areas can be identical or be partially identical, but also be chosen completely different.

Darüber hinaus ist es möglich, dass die Bereiche übereinander und/oder untereinander und/oder nebeneinander angeordnet sind.Moreover, it is possible that the areas are arranged one above the other and / or one below the other and / or next to each other.

Des weiteren kann vorgesehen sein, dass ein großer erster Bereich vorgesehen ist, der ein größeres Volumen als der wenigstens eine weitere zweite Bereich aufweist. Insbesondere ist dabei denkbar, dass ein Bereich der Hauptbereich des Kühlteils für die Einlagerung von Kühlgut ist und der zweite Bereich ein Auszugfach für die Kühlung z.B. von Gemüse ist.Furthermore, it can be provided that a large first area is provided which has a larger volume than the at least one further second area. In particular, it is conceivable that one region is the main region of the cooling part for the storage of goods to be cooled, and the second region is an extraction compartment for the cooling, e.g. of vegetables is.

Es ist möglich, dass der und/oder die weiteren zweiten Bereiche unterhalb des großen ersten Bereichs angeordnet sind.It is possible that the and / or the further second regions are arranged below the large first region.

Ferner ist denkbar, dass wenigstens ein zweiter Bereich eine 0°C-Zone bzw. ein BioFresh-Bereich ist. Vorzugsweise ist ein derartiger zweiter Bereich als Schubfach oder Auszugfach ausgeführt. Besonders vorteilhaft ist es, wenn das Auszugfach transparent ausgeführt ist. Grundsätzlich ist denkbar, dass sämtliche zweiten Bereiche als BioFresh-Fächer ausgeführt sind. Erfindungsgemäß ist hinter einer Wandung der Bereiche wenigstens ein Luftführungsmittel vorgesehen ist und dass die Luftumwälzmittel in und/oder an der Wandung des Innenraums angeordnet und mit dem Luftführungsmittel für die Luftumwälzung in Verbindung stehen. Luftführungsmittel können beispielsweise Kanäle, Schächte, Klappen und/oder andere Umlenkmittel für Luft sein, die entweder zu dem jeweiligen Bereich hinzuführen oder aus dem jeweiligen Bereich abzuführen ist. Grundsätzlich ist denkbar, dass die Bereiche gemeinsame, durchgängige Wandungen haben, wobei die Bereiche durch Zwischenböden voneinander abgetrennt werden.Furthermore, it is conceivable that at least a second area is a 0 ° C zone or a BioFresh area. Preferably, such a second area is designed as a drawer or pull-out compartment. It is particularly advantageous if the pull-out compartment is designed to be transparent. In principle, it is conceivable that all second areas are designed as BioFresh subjects. According to the invention, at least one air guiding means is provided behind a wall of the regions, and the air circulating means are arranged in and / or on the wall of the interior and communicate with the air guiding means for air circulation. Air guiding means may be, for example, channels, shafts, flaps and / or other deflection means for air, which either lead to the respective area or be discharged from the respective area. In principle, it is conceivable that the areas have common, continuous walls, the areas being separated from one another by intermediate floors.

Weiter ist möglich, dass Luft aus dem Luftführungsmittel durch die Luftumwälzmittel in den dem Luftumwälzmittel zugeordneten Bereich einblasbar ist.Furthermore, it is possible for air from the air guidance means to be able to be inflated by the air circulation means in the region assigned to the air circulation means.

Des weiteren kann vorteilhafter Weise vorgesehen sein, dass das Luftumwälzmittel ein Ventilator ist. In diesem Zusammenhang ist denkbar, dass die Ansteuerung der Ventilatoren über eine Steuerungs- und/oder Regelungseinheit erfolgt. Dabei kann es sich um die Gerätesteuerung des Kühl- und/oder Gefriergeräts handeln. Beispielsweise über die Ansteuerung der Drehzahl eines Ventilators kann somit die Temperatur in einem Bereich bzw. Fach eingeregelt werden. Erfindungsgemäß umfasst das Luftführungsmittel einen Kühlluftschacht und einen Luftabzugskanal. Außerdem ist denkbar, dass im Kühlluftschacht wenigstens ein Verdampfer, vorzugsweise ein Zentralverdampfer angeordnet ist. Ein derartiger Zentralverdampfer kann sich dabei nahezu über die gesamte Höhe des Innenraums erstrecken und für die Abkühlung der Luft für sämtliche Bereiche dienen. Besonders vorteilhaft ist es, wenn mehrere Bereiche übereinander angeordnet sind und der Zentralverdampfer sich über alle Bereiche erstreckt. Dadurch ergibt sich der Vorteil, dass die am Zentralverdampfer vorbeigeführte und hierdurch abgekühlte Luft ohne große Umwege direkt mittels des jeweiligen Luftumwälzmittels in den jeweiligen Bereich bzw. das jeweilige Fach eingeblasen werden kann.Furthermore, it can be advantageously provided that the air circulation means is a fan. In this context, it is conceivable that the actuation of the fans takes place via a control and / or regulating unit. This may be the device control of the refrigerator and / or freezer. For example, by controlling the speed of a fan, the temperature can thus be adjusted in an area or compartment. According to the invention, the air guidance means comprises a cooling air shaft and an air exhaust duct. It is also conceivable that at least one evaporator, preferably a central evaporator is arranged in the cooling air shaft. Such a central evaporator can extend almost over the entire height of the interior and serve for the cooling of the air for all areas. It is particularly advantageous if several areas are arranged one above the other and the central evaporator extends over all areas. This results in the advantage that the air passed by the central evaporator and thereby cooled air can be injected directly into the respective area or the respective compartment by means of the respective air circulation means without great detours.

Von Vorteil ist es, wenn die Bereiche mit einem Luftabzugskanal verbunden sind. Hierdurch wird es beispielsweise möglich, zunächst die warme Luft aus den jeweiligen Bereichen bzw. Temperaturzonen zu bündeln und sodann gesammelt abzukühlen, also beispielsweise einem Zentralverdampfer zuführen bzw. daran vorbeizuführen und hierdurch abzukühlen.It is advantageous if the areas are connected to an air extraction duct. This makes it possible, for example, first to concentrate the warm air from the respective regions or temperature zones and then to cool it down, ie to supply, for example, to a central evaporator or to pass it and thereby cool it.

Weiterhin kann vorgesehen sein, dass die Bereiche jeweils über eine Luftaustrittöffnung mit einem gemeinsamen Luftabzugskanal verbunden sind. Diese Ausgestaltung ist platzsparend und erlaubt z.B. eine Ausnutzung des Kamineffektes und zwar insbesondere dann, wenn der Luftabzugskanal senkrecht angeordnet ist. Erfindungsgemäß sind wenigstens ein Kühlluftschacht und ein Luftabzugskanal vorgesehen, wobei beide hinter der rückseitigen Wandung der Bereiche angeordnet sind. Beispielsweise ist in diesem Zusammenhang vorstellbar, dass Kühlluftschacht und Luftabzugskanal gemeinsam in dem Schacht, der durch die rückseitige Wandung der Bereiche und durch die rückseitige Innenseite des Innenbehälters der Kühl- und/oder Gefriergeräts ausgebildet ist, untergebracht sind. Erfindungsgemäß werden Kühlluftschacht und Luftabzugskanal durch eine gemeinsame Trennwand getrennt, wobei im oberen Teil der Trennwand über eine Öffnung Luft vom Luftabzugskanal in den Kühlluftschacht übertritt.Furthermore, it can be provided that the areas are each connected via an air outlet opening with a common air exhaust duct. This embodiment is space-saving and allows, for example, an exploitation of the chimney effect and in particular when the air outlet duct is arranged vertically. According to the invention, at least one cooling air shaft and an air exhaust duct are provided, both of which are arranged behind the rear wall of the areas. For example, in this connection, it is conceivable that the cooling air duct and the air exhaust duct are accommodated together in the duct which is formed by the rear wall of the regions and by the rear inside of the inner container of the refrigerator and / or freezer. According to the invention, the cooling air shaft and the air outlet channel are separated by a common partition wall, wherein in the upper part of the partition wall, air passes from the air exhaust duct into the cooling air duct via an opening.

Weitere Einzelheiten und Vorteile der Erfindung sollen nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.Further details and advantages of the invention will now be explained in more detail with reference to an embodiment shown in the drawing.

Bei einer Ausführungsform mit Auszugfächern ist beispielsweise denkbar, dass transparente Schubfächer in die Bereiche 22, 24, 26 ein- und ausgeschoben werden können.It is preferably provided that the three lower regions 22, 24, 26 are 0 ° C zones or BioFresh zones. In this case, the areas 22, 24, 26 can be designed as compartments or as pull-out compartments. In an embodiment with pull-out compartments, for example, it is conceivable that transparent drawers can be inserted and ejected into the areas 22, 24, 26.

Die Bereiche 20, 22, 24, 26 können grundsätzlich jeweils eine von einander unterschiedliche, aber auch identische Temperatur aufweisen. So kann vorgesehen sein, dass die Temperatur im ersten Bereich 20 ca. 4°C ist, während die Temperatur in den Bereichen 22, 24, 26 jeweils ca. 0°C ist. Grundsätzlich kann ebenfalls vorgesehen sein, dass die Temperatur in den Bereichen 22, 24, 26 höher oder auch niedriger als 0°C ist.The regions 20, 22, 24, 26 can in principle each have a different but also identical temperature. It can thus be provided that the temperature in the first region 20 is approximately 4 ° C., while the temperature in the regions 22, 24, 26 is approximately 0 ° C. in each case. In principle, it can also be provided that the temperature in the regions 22, 24, 26 is higher or even lower than 0 ° C.

Die Bereiche 20, 22, 24, 26 sind zur Ausbildung einer eigenständigen Temperaturzone durch durchgehende Zwischenböden 14 voneinander abgetrennt. In diesen Zwischenböden können zusätzliche Isolationsschichten eingearbeitet sein, die jedoch in den Figuren nicht näher dargestellt sind.The areas 20, 22, 24, 26 are separated from each other to form an independent temperature zone by continuous shelves 14. In these shelves additional insulation layers may be incorporated, which are not shown in detail in the figures.

Jedem Bereich 20, 22, 24, 26 ist jeweils ein als Ventilator 30 ausgeführtes Luftumwälzmittel 30 sowie eine Luftabzugsöffnung 120, 122, 124, 126 zugeordnet. Hierdurch wird eine sehr genaue Temperaturregulierung im jeweiligen Kühlbereich 20, 22, 24, 26 erreicht.Each area 20, 22, 24, 26 is in each case assigned an air circulation means 30 designed as a fan 30 and an air discharge opening 120, 122, 124, 126. As a result, a very precise temperature regulation in the respective cooling region 20, 22, 24, 26 is achieved.

Die Ventilatoren 30 blasen aus dem Kühlluftschacht 30, der sich hinter der gemeinsamen rückseitigen Wandung 16 (vgl. Fig. 2 und 3) der Bereiche 20, 22, 24, 26 befindet, abgekühlte Luft L in die jeweiligen Bereiche 20, 22, 24, 26 ein. Die Luft L strömt sodann durch den jeweiligen Bereich 20, 22, 24, 26 und verläßt diesen durch die dem Bereich 20, 22, 24, 26 zugeordnete Luftaustrittöffnung 120, 122, 124, 126 in den kaminartigen Luftkanal 50 zur Abführung der erwärmten Luft L.The fans 30 blow from the cooling air duct 30, which is behind the common rear wall 16 (see. Fig. 2 and 3 ) of the regions 20, 22, 24, 26, cooled air L in the respective regions 20, 22, 24, 26 a. The air L then flows through the respective region 20, 22, 24, 26 and leaves it through the air outlet opening 120, 122, 124, 126 associated with the region 20, 22, 24, 26 into the chimney-like air channel 50 for the removal of the heated air L. ,

Der Kühlluftschacht 30 sowie der kaminartige Luftkanal 50 befinden beide sich hinter rückseitigen Wandung 16 der Bereiche 20, 22, 24, 26 und werden durch die Trennwand 62 von einander getrennt und durch die kopfseitig angeordnete Öffnung 60 miteinander verbunden. Sowohl der Kühlluftschacht 30 als auch der kaminartige Luftkanal 50 sind über ihre gesamte Höhe durchgängig ausgeführt und werden nicht durch die Zwischenböden 14 unterteilt. Die Zwischenböden 14 enden an der gemeinsamen rückseitigen Wandung 16 der Bereiche 20, 22, 24, 26.The cooling air shaft 30 and the chimney-like air channel 50 are both located behind the rear wall 16 of the regions 20, 22, 24, 26 and are separated by the partition wall 62 of each other and connected by the head side opening 60 together. Both the cooling air duct 30 and the chimney-like air duct 50 are designed to be continuous over their entire height and are not divided by the shelves 14. The shelves 14 terminate at the common rear wall 16 of the areas 20, 22, 24, 26th

Die aus den Bereichen 20, 22, 24, 26 abgeführte, erwärmte Luft steigt im Luftkanal 50 nach oben und tritt über die Öffnung 60 in den Kühlluftschacht 30 ein. Dort strömt die Luft L am Zentralverdampfer 70 entlang und kühlt hierdurch ab. Danach wird die Luft erneut durch die Ventilatoren 30 in die jeweiligen Bereiche 20, 22, 24, 26 eingeblasen.The discharged from the areas 20, 22, 24, 26, heated air rises in the air duct 50 upwards and enters through the opening 60 in the cooling air duct 30 a. There, the air L flows along the central evaporator 70 and thereby cools. Thereafter, the air is again blown through the fans 30 in the respective regions 20, 22, 24, 26.

Der Ventilator 30, der dem obersten Bereich 20 zugeordnet ist, befindet sich mittig im unteren Teil der rückseitigen Wandung 16 des Bereichs 20 und ist in der Wandung 16 befestigt. Die dem Bereich 20 zugeordnete Luftaustrittsöffnung 120 befindet demgegenüber im oberen Teil der rückseitigen Wandung 16 des Bereichs 20. Die Ventilatoren 30 der unteren Bereiche 22, 24, 26 sind ebenfalls bodenseitig orientiert, während die jeweilige Luftaustrittöffnung kopfseitig orientiert ist.The fan 30, which is assigned to the uppermost region 20, is located centrally in the lower part of the rear wall 16 of the region 20 and is fastened in the wall 16. In contrast, the air outlet opening 120 assigned to the area 20 is located in the upper part of the rear wall 16 of the area 20. The fans 30 of the lower areas 22, 24, 26 are likewise oriented on the bottom side, while the respective air outlet opening is oriented on the head side.

Fig. 2 zeigt den Schnitt B-B durch das in Fig. 1 gezeigte Kühl- und/oder Gefriergerät. Aus dieser Schnittzeichnung wird die Führung der L nochmals verdeutlicht. Durch die Ventilatoren 30 wird die Luft L aus dem Kühlluftschacht 40 mit dem Zentralverdampfer 70 jeweils bodenseitig in die Bereiche bzw. Fächer 20, 22, 24, 26 bzw. Temperaturzonen 20, 22, 24, 26 eingeblasen. Die sich im Bereich 20 bzw. den Fächern 22, 24, 26 erwärmende Luft L steigt nach oben auf und verläßt den Bereich 20 bzw. die Fächer 22, 24, 26 über die jeweils zugeordneten Luftaustrittsöffnungen 120, 122, 124, 126 in den Luftkanal 50. Fig. 2 shows the section BB through the in Fig. 1 shown refrigerator and / or freezer. From this sectional drawing the guidance of the L is again clarified. By means of the fans 30, the air L from the cooling air shaft 40 with the central evaporator 70 is in each case blown on the bottom side into the areas or compartments 20, 22, 24, 26 or temperature zones 20, 22, 24, 26. The air L heated in the region 20 or the compartments 22, 24, 26 rises upwards and leaves the region 20 or the compartments 22, 24, 26 via the respectively assigned air outlet openings 120, 122, 124, 126 into the air channel 50th

Fig. 3 zeigt den Schnitt A-A mit Blickrichtung von oben nach unten durch das in Fig. 1 und 2 gezeigte Kühl- und/oder Gefriergerät. In dieser Schnittansicht ist die Anordnung des Kühlluftschachtes 40 mit dem darin angeordneten Zentralverdampfer 70 und dem kaminartigen Luftkanal 50 zur Abführung der erwärmten Luft L hinter der rückseitigen Wandung 16 gezeigt. Fig. 3 shows the section AA looking from top to bottom through the in Fig. 1 and 2 shown refrigerator and / or freezer. In this sectional view, the arrangement of the cooling air shaft 40 with the central evaporator 70 arranged therein and the chimney-like air duct 50 for discharging the heated air L behind the rear wall 16 is shown.

Grundsätzlich kann vorgesehen sein, dass über eine nicht näher dargestellte Gerätesteuerung und -regelung die Temperatur in jedem Fach einzeln vorgegeben und eingeregelt wird. Dabei ist es nicht zwingend notwendig, dass die Ventilatoren synchron angesteuert und betrieben werden. Vorteilhafterweise ist es möglich, die Ventilatoren je nach Bedarf und unabhängig voneinander z.B. hinsichtlich Drehzahl anzusteuern und hierdurch die Temperatur im jeweiligen Bereich bzw. Fach 20, 22, 24, 26 einzuregeln. Über nicht näher dargestellte Klappen kann des weiteren vorgesehen sein, den Bereich 20 bzw. eines oder mehrere der Fächer 22, 24, 26 beispielsweise zeitweilig aus dem Zirkulationskreislauf der Luft L auszukoppeln. Derartige Klappen sind bei einer derartigen Ausführungsform eines Kühl- und/oder Gefriergeräts 10 dem Ventilator 30 und auch den Luftaustrittsöffnungen 120, 122, 124, 126 zugeordnet und können ebenfalls vorzugsweise über die Gerätesteuerung und -regelung angesteuert werden.In principle, it can be provided that the temperature in each compartment is predetermined and adjusted individually via a device control and regulation, not shown in detail. It is not absolutely necessary that the fans are controlled and operated synchronously. Advantageously, it is possible to ventilate the fans as needed and independently e.g. to control in terms of speed and thereby regulate the temperature in the respective area or compartment 20, 22, 24, 26. Flaps not shown in detail may further be provided to decouple the region 20 or one or more of the compartments 22, 24, 26 temporarily, for example, from the circulation circuit of the air L. Such flaps are associated with the fan 30 and the air outlet openings 120, 122, 124, 126 in such an embodiment of a refrigerator and / or freezer 10 and can also be preferably controlled by the device control and regulation.
