Description

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem ersten Kompartiment und mit wenigstens einem zweiten Kompartiment, wobei das zweite Kompartiment im Betrieb des Gerätes bei einer geringeren oder derselben Temperatur betrieben wird wie/als das erste Kompartiment, wobei wenigstens eine horizontale Trennplatte vorgesehen ist, die das erste Kompartiment von dem zweiten Kompartiment trennt, und wobei wenigstens ein Verdampfer vorgesehen ist, der zur Kühlung des ersten und/oder des zweiten Kompartimentes dient.The present invention relates to a refrigerator and / or freezer with at least a first compartment and at least a second compartment, wherein the second compartment is operated at a lower or the same temperature during operation of the device as / as the first compartment, wherein at least one horizontal Separating plate is provided which separates the first compartment from the second compartment, and wherein at least one evaporator is provided which serves to cool the first and / or the second compartment.

Aus dem Stand der Technik sind Kühl- und/oder Gefriergeräte bekannt, die ein unten angeordnetes Kaltlagerfach und ein oben angeordnetes Kühlkompartiment aufweisen. Zwischen beiden Kompartimenten befindet sich eine isolierte horizontale Trennplatte. Des Weiteren befindet sich im rückwärtigen Bereich des Kühlkompartimentes eine vertikale Trennplatte, die einen Kühlluftkanal zu dem Aufnahmeraum für das Kühlgutes hin abtrennt. In diesem Kühlluftkanal befindet sich ein Verdampfer. Im oberen Bereich des Kühlluftkanals befindet sich ein Ventilator, der Luft aus dem Kühlkompartiment in den Kühlluftkanal fördert. Die Luft wird in dem Kühlluftkanal mittels des Verdampfers gekühlt und gelangt dann in das Kaltlagerfach. Von diesem strömt die Luft in das Kühlkompartiment.Cooling and / or freezers are known from the prior art, which have a cold storage compartment arranged at the bottom and a cooling compartment arranged at the top. Between both compartments there is an insulated horizontal partition plate. Furthermore, located in the rear area of the Kühlkompartimentes a vertical partition plate which separates a cooling air duct to the receiving space for the refrigerated goods out. In this cooling air duct is an evaporator. In the upper part of the cooling air duct is a fan, which conveys air from the cooling compartment into the cooling air duct. The air is cooled in the cooling air duct by means of the evaporator and then enters the cold storage compartment. From this, the air flows into the cooling compartment.

Die vertikale Trennplatte wird mit einer Styroporeinlage isoliert, um zu verhindern, dass sich aufgrund des kalten, hinter der vertikalen Trennplatte angeordneten Verdampfers Kondensat auf der dem Kühlraum zugewandten Seite der vertikalen Trennplatte bildet.The vertical partition plate is insulated with a Styrofoam insert to prevent condensate from forming on the cold side of the vertical partition due to the cold evaporator located behind the vertical partition.

Die horizontale Trennplatte wird aus Stabilitätsgründen ausgeschäumt.The horizontal partition plate is foamed for stability reasons.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, das auf die genannte Isolation verzichtet werden kann. Damit werden Kosten eingespart und Nutzinhaltsverluste aufgrund der Isolation vermieden.The present invention is based on the object to further develop a refrigerator and / or freezer of the type mentioned in that the said isolation can be dispensed with. This saves costs and prevents loss of useful content due to isolation.

Diese Aufgabe wird durch ein Gerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a device having the features of claim 1.

Danach ist vorgesehen, dass der wenigstens eine Verdampfer in oder an der horizontalen Trennplatte angeordnet ist und dass wenigstens ein Ventilator vorgesehen ist, der derart angeordnet ist, dass er in zumindest einem Betriebsmodus des Gerätes die von dem Verdampfer gekühlte Luft in das erste und/oder in das zweite Kompartiment fördert. Der Verdampfer des Gerätes befindet sich erfindungsgemäß somit in oder an der genannten horizontalen Trennplatte, die das erste von dem zweiten Kompartiment trennt.Thereafter, it is provided that the at least one evaporator is arranged in or on the horizontal partition plate and that at least one fan is provided, which is arranged such that it in at least one operating mode of the device cooled by the evaporator air in the first and / or promotes into the second compartment. The evaporator of the device is thus according to the invention in or on said horizontal partition plate, which separates the first from the second compartment.

Durch das Anbringen des Verdampfers in oder an der horizontalen Trennplatte ist diese auch ohne Ausschäumen hinreichend stabil, Kühlgut zu tragen.By attaching the evaporator in or on the horizontal partition plate this is sufficiently stable without foaming to carry refrigerated goods.

Vorzugsweise ist vorgesehen, dass der oben zum Stand der Technik beschriebene Verdampfer hinter der vertikalen Trennplatte nicht vorhanden ist, so dass die vertikale Trennplatte dementsprechend auch nicht mehr isoliert werden muss.It is preferably provided that the evaporator described above with reference to the prior art does not exist behind the vertical separating plate, so that the vertical separating plate does not have to be insulated accordingly.

Vorzugsweise ist des Weiteren vorgesehen, dass der in oder an der horizontalen Trennplatte vorhandene Verdampfer der einzige Verdampfer ist, der zur Kühlung des ersten, insbesondere des Kühlkompartimentes und des zweiten, insbesondere des Kaltlagerfachs dient. Vorzugsweise ist somit kein anderer Verdampfer vorgesehen, der zur Kühlung von Kühlkompartiment und Kaltlagerfach dient. Denkbar ist es, dass das erste Kompartiment und/oder das zweite Kompartiment beispielsweise durch ein Kaltlagerfach und/oder durch ein Kühlkompartiment gebildet werden.Preferably, it is furthermore provided that the evaporator present in or on the horizontal separating plate is the only evaporator which serves for cooling the first, in particular the cooling compartment, and the second, in particular the cold storage compartment. Preferably, therefore, no other evaporator is provided, which serves for cooling of Kühlkompartiment and cold storage compartment. It is conceivable it is that the first compartment and / or the second compartment are formed for example by a cold storage compartment and / or by a Kühlkompartiment.

Grundsätzlich ist es denkbar, das erste und das zweite Kompartiment bei identischen Temperaturen oder auch bei unterschiedlichen Temperaturen zu betreiben. Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass das unterhalb der Trennplatte befindliche Kompartiment bei einer geringeren Temperatur betrieben wird als das oberhalb der Trennplatte befindliche Kompartiment.In principle, it is conceivable to operate the first and the second compartment at identical temperatures or even at different temperatures. A preferred embodiment of the invention is that the compartment located below the partition plate is operated at a lower temperature than the compartment located above the partition plate.

Sofern eine vertikale Trennplatte vorhanden ist, dient diese vorzugsweise erfindungsgemäß nur noch dazu, die von dem Verdampfer gekühlte kalte Luft in das oder die Kompartimente, vorzugsweise in das Kühlkompartiment, vorzugsweise in dessen ganz oberen Bereich zu führen und kann deshalb auch schmaler ausgeführt werden als dies aus dem Stand der Technik bekannt ist. In dem genannten Kühlluftkanal ist vorzugsweise somit kein Verdampfer vorgesehen. Entsprechende Ausführungen können auch für das Kaltlagerfach oder ein sonstiges Kompartiment gelten.If a vertical partition plate is present, this preferably only serves according to the invention to guide the cold air cooled by the evaporator into the compartment or compartments, preferably into the cooling compartment, preferably in its very upper area, and can therefore be made narrower than this is known from the prior art. In the said cooling air duct, therefore, preferably no evaporator is provided. Corresponding designs can also apply to the cold storage compartment or another compartment.

Bezüglich des unterhalb der horizontalen Trennplatte angeordneten Kompartimentes, insbesondere des Kaltlagerfachs ist es vorzugsweise jedoch vorgesehen, dass kein Kühlluftkanal angeordnet ist, sondern dass die von dem Verdampfer gekühlte Luft unmittelbar in dieses Kompartiment gelangt.With regard to the arranged below the horizontal partition plate compartment, in particular the cold storage compartment, it is preferably provided, however, that no cooling air duct is arranged, but that the air cooled by the evaporator passes directly into this compartment.

Vorzugsweise ist vorgesehen, dass das zweite Kompartiment, insbesondere das Kaltlagerfach unterhalb und das erste Kompartiment, insbesondere das Kühlkompartiment oberhalb der genannten horizontalen Trennplatte angeordnet ist.It is preferably provided that the second compartment, in particular the cold storage compartment below and the first compartment, in particular the cooling compartment is arranged above said horizontal partition plate.

Wie oben ausgeführt, besteht eine vorteilhafte Ausgestaltung der Erfindung darin, dass die horizontale Trennplatte keine oder eine weniger starke Ausschäumung oder sonstige Wärmedämmung als bei bekannten Geräten aufweist.As stated above, an advantageous embodiment of the invention is that the horizontal partition plate has no or less strong foaming or other thermal insulation than in known devices.

Weiterhin kann vorgesehen sein, dass in dem ersten und/oder in dem zweiten Kompartiment wenigstens ein Kühlluftkanal angeordnet ist, der durch wenigstens eine Trennplatte, vorzugsweise wenigstens eine vertikale Trennplatte zu dem Aufnahmeraum für das Kühlgut hin abgetrennt ist und dass diese Trennplatte keine Wärmedämmung aufweist. Dies bringt nicht nur Kostenvorteile mit sich, sondern auch einen Vorteil hinsichtlich des verfügbaren Nutzraums.Furthermore, it can be provided that in the first and / or in the second compartment at least one cooling air duct is arranged, which is connected through at least one partition plate, preferably at least one vertical partition plate to the receiving space is separated for the refrigerated goods and that this partition plate has no thermal insulation. This not only brings cost advantages, but also an advantage in terms of available usable space.

In einer Ausgestaltung der Erfindung ist vorgesehen, dass wenigstens ein Kühlluftkanal angeordnet ist, wobei der Kühlluftkanal derart ausgebildet ist, dass er wenigstens einen Einlass aufweist, in den von dem Verdampfer gekühlte Luft mittels des Ventilators eingeführt wird und wenigstens einen Auslass aufweist, aus dem von dem Verdampfer gekühlte Luft in das Kompartiment, insbesondere in das Kühlkompartiment eintritt. Vorzugsweise befindet sich der wenigstens eine Einlass auf Höhe der horizontalen Trennplatte und vorzugsweise in deren hinteren Bereich. Vorzugsweise ist es vorgesehen, dass der Auslass in einem oberen Bereich des Kompartiments, vorzugsweise ganz oben in dem Kühlkompartiment angeordnet ist. Abweichend von aus dem Stand der Technik bekannten Anordnungen durchströmt in diesem Fall somit die Kaltluft das fragliche Kompartiment, insbesondere das Kühlkompartiment von oben nach unten.In one embodiment of the invention it is provided that at least one cooling air duct is arranged, wherein the cooling air duct is formed such that it has at least one inlet, is introduced into the air cooled by the evaporator by means of the fan and at least one outlet, from which the evaporator cooled air enters the compartment, in particular in the cooling compartment. Preferably, the at least one inlet is located at the level of the horizontal partition plate, and preferably in the rear area thereof. It is preferably provided that the outlet is arranged in an upper region of the compartment, preferably at the very top in the cooling compartment. Notwithstanding arrangements known from the prior art, in this case the cold air thus flows through the compartment in question, in particular the cooling compartment, from top to bottom.

Vorzugsweise ist vorgesehen, dass in dem Kühlluftkanal wenigstens eine verstellbare Klappe oder ein sonstiges Drosselelement angeordnet ist, mittels dessen der Volumenstrom der durch den Kühlluftkanal strömenden Kaltluft veränderbar ist oder mittels dessen der Kühlluftkanal gänzlich abgesperrt werden kann. Bei diesem Drosselelement kann es sich beispielsweise um eine verschwenkbare Klappe oder auch um einen Schieber oder dergleichen handeln.It is preferably provided that at least one adjustable flap or another throttle element is arranged in the cooling air passage, by means of which the volume flow of cold air flowing through the cooling air passage is changeable or by means of which the cooling air passage can be completely shut off. This throttle element may be, for example, a pivotable flap or a slider or the like.

Der wenigstens eine Ventilator kann in wenigstens einem Betriebsmodus durch den Verdampfer gekühlte Kaltluft unmittelbar oder mittelbar, vorzugsweise durch einen oder mehrere Kühlluftkanäle in das erste und/oder in das zweite Kompartiment, vorzugsweise in das Kühlkompartiment und/oder in das Kaltlagerfach fördern.The at least one fan may, in at least one operating mode, convey cold air cooled by the evaporator directly or indirectly, preferably through one or more cooling air ducts into the first and / or second compartment, preferably into the cooling compartment and / or into the cold storage compartment.

Weiterhin kann vorgesehen sein, dass der Ventilator derart angeordnet ist, dass durch den Ventilator geförderte Luft sowohl in das erste Kompartiment, vorzugsweise in das Kühlkompartiment als auch in das zweite Kompartiment, vorzugsweise in das Kaltlagerfach geleitet wird, wobei vorzugsweise vorgesehen ist, dass der Ventilator in seiner Position verstellbar ist, so dass das Verhältnis des Volumenstroms von in das erste Kompartiment geförderter Luft zu dem in das zweite Kompartiment geförderter Luft veränderbar ist.Furthermore, it can be provided that the fan is arranged such that air conveyed by the fan is directed into both the first compartment, preferably in the cooling compartment and in the second compartment, preferably in the cold storage compartment, wherein it is preferably provided that the fan is adjustable in position, so that the ratio of the volume flow can be changed from the conveyed in the first compartment air to the air supplied to the second compartment.

Beispielsweise ist es denkbar, dass zumindest eine Steuer- und/oder Regelungseinheit vorgesehen ist, die die Position des Ventilators und/oder dessen Drehzahl und/oder dessen Betriebszustand (eingeschaltet oder ausgeschaltet) und/oder auch eines oder mehrere der genannten Drosselelemente in Abhängigkeit davon ansteuert oder regelt, wie der Kältebedarf in dem ersten und/oder in dem zweiten Kompartiment ist.For example, it is conceivable that at least one control and / or regulating unit is provided which determines the position of the fan and / or its rotational speed and / or operating state (switched on or off) and / or one or more of said throttle elements in dependence thereon controls or regulates how the refrigeration demand in the first and / or in the second compartment is.

Die horizontale Trennplatte hat eine zur Tür des Gerätes weisende Vorderseite und eine zur Rückwand des oder der Innenbehälter gewandte Rückseite. Vorzugsweise ist vorgesehen, dass der Ventilator in oder an der horizontalen Trennplatte im Bereich der Rückseite der Trennplatte angeordnet ist.The horizontal partition plate has a facing the door of the device front and a facing the rear wall of the inner container or the back. It is preferably provided that the fan is arranged in or on the horizontal partition plate in the region of the rear side of the partition plate.

In einer Ausgestaltung der Erfindung ist vorgesehen, dass unterhalb des an oder in der horizontalen Trennplatte angeordneten Verdampfers wenigstens ein Tauwasserauffangbehältnis angeordnet ist, das wasserundurchlässig und luftdurchlässig ist, so dass von dem Verdampfer gekühlte Luft durch das Tauwasserauffangbehältnis hindurch nach unten in das Kompartiment bzw. Kaltlagerfach oder sonstige Kompartiment fallen kann. Diese Ausgestaltung der Erfindung bringt den Vorteil mit sich, dass im statischen Betrieb des Gerätes die von dem Verdampfer gekühlte Luft durch das Tauwasserauffangbehältnis hindurch nach unten in das unterhalb des Verdampfers angeordnete Kompartiment strömen kann. Die Luftdurchlässigkeit des Tauwasserauffangbehältnisses verhindert ein horizontales Entlangströmen der kalten, vom Verdampfer abgekühlten Luft an dem Tauwasserauffangbehältnis. Die Luftdurchlässigkeit erlaubt dieser kalten Luft vertikal nach unten, vorzugsweise in den Biofresh-Lagerbereich bzw. in das Kaltlagerfach zu strömen bzw. zu "fallen".In one embodiment of the invention it is provided that below the arranged on or in the horizontal partition plate evaporator at least one condensation collection container is arranged, which is impermeable to water and permeable to air, so that cooled by the evaporator air through the condensation collection container down through the compartment or cold storage compartment or other compartment may fall. This embodiment of the invention has the advantage that during static operation of the device, the air cooled by the evaporator can flow through the condensate collection container down into the compartment arranged below the evaporator. The air permeability of the condensate collection container prevents horizontal flow along the cold, cooled by the evaporator air at the condensation collection container. The air permeability allows this cold air vertically downwards, preferably to flow or "fall" in the Biofresh storage area or in the cold storage compartment.

Dadurch wird verhindert, dass sich die Oberflächentemperatur dieses Tauwasserauffangbehältnisses zu weit abkühlt und damit den Taupunkt unterschreitet. Die aufgrund der höheren Dichte nach unten strömende kalte Luft bewirkt ein vorzugsweise vertikal nach oben Strömen der Luft, die sich in dem unterhalb des Verdampfers befindlichen Kompartiment befindet und die erwärmt und gegebenenfalls befeuchtet ist. Diese Luft kann nun durch das luftdurchlässige Tauwasserauffangbehältnis hindurch strömen und kondensiert dann an dem Verdampfer aus. Das Tauwasserauffangbehältnis dient somit in bevorzugter Ausgestaltung der Erfindung zu einem Luftaustausch in zwei Richtungen, nämlich einerseits zu einem Strömen von Kaltluft vom Verdampfer in das unterhalb des Verdampfers angeordnete Kompartiment, insbesondere in das Kaltlagerfach, und darüber hinaus zu einem ein Strömen von erwärmter und/oder feuchter Luft von unten durch das Tauwasserauffangbehältnis hindurch zu dem Verdampfer.This prevents the surface temperature of this condensation collection container from cooling too far and thus falling below the dew point. The cold air flowing downwards due to the higher density causes a preferably vertically upward flow of the air, which is located in the compartment located below the evaporator and which heats and optionally humidifies is. This air can now flow through the air-permeable condensate collection container and then condenses on the evaporator. The condensate collection container thus serves in a preferred embodiment of the invention for an exchange of air in two directions, namely on the one hand to a flow of cold air from the evaporator into the arranged below the evaporator compartment, in particular in the cold storage compartment, and in addition to a flow of heated and / or moist air from below through the condensate collection container through to the evaporator.

Der Begriff Tauwasserauffangbehältnis ist allgemein zu verstehen und kam beispielsweise durch eine Schale, ein Gewebe, ein Vlies oder dergleichen gebildet werden.The term dew-water collecting container is to be understood generally and has been formed, for example, by a shell, a fabric, a fleece or the like.

Vorzugsweise ist das Tauwasserauffangbehältnis geneigt, vorzugsweise zur Seite oder auch nach hinten, d.h. zur Rückwand des Gerätes hin, so dass das Tauwasser entweder seitlich oder nach hinten abläuft.Preferably, the condensation collecting container is inclined, preferably to the side or to the rear, i. towards the rear wall of the unit, so that the condensation water runs either laterally or to the rear.

Erfindungsgemäß ist wenigstens ein Ventilator vorgesehen, der derart angeordnet ist, dass er im Betrieb des Ventilators durch den Verdampfer gekühlte Kaltluft in das erste und/oder zweite Kompartiment, insbesondere in das Kühlkompartiment und/oder in das Kaltlagerfach fördert. Vorzugsweise ist vorgesehen, dass das Gerät wenigstens eine Steuer- oder Regelungseinheit aufweist, die den Ventilator ansteuert oder regelt, wobei die Steuer- oder Regelungseinheit derart ausgebildet ist, dass sie den Ventilator zur Einstellung eines statischen Kühlmodus ausschaltet und zur Einstellung eines dynamischen Kühlmodus einschaltet.According to the invention, at least one fan is provided, which is arranged in such a way that, during operation of the fan, it conveys cooled cold air through the evaporator into the first and / or second compartment, in particular into the cooling compartment and / or into the cold storage compartment. It is preferably provided that the device has at least one control or regulating unit which controls or regulates the fan, wherein the control or regulating unit is designed such that it switches off the fan to set a static cooling mode and turns on to set a dynamic cooling mode.

In einer bevorzugten Ausgestaltung der Erfindung ist das Gerät somit "statisch" und "dynamisch" betreibbar. In dem Fall des statischen Betriebs ist der Ventilator ausgeschaltet. In einem dynamischen Betrieb hingegen ist der Ventilator eingeschaltet und fördert aktiv die von dem Verdampfer gekühlte Luft in das erste und/oder zweite Kompartiment, d.h. vorzugsweise in das Kühlkompartiment und/oder in das Kaltlagerfach.In a preferred embodiment of the invention, the device is thus "static" and "dynamic" operable. In the case of static operation, the fan is off. In a dynamic operation, however, the fan is turned on and actively promotes the cooled air from the evaporator in the first and / or second compartment, ie preferably in the cooling compartment and / or in the cold storage compartment.

Ob der statische oder dynamische Betriebsmodus gewählt wird, kann beispielsweise von dem Kältebedarf abhängen, der in dem oder den Kompartimenten besteht.Whether the static or dynamic mode of operation is selected, for example, may depend on the refrigeration demand that exists in the compartment or compartments.

In weiterer Ausgestaltung der Erfindung ist die wenigstens eine Steuer- oder Regelungseinheit derart ausgebildet, dass sie in Abhängigkeit von dem Kältebedarf in dem ersten und/oder zweiten Kompartiment, vorzugsweise in dem Kühlkompartiment und/oder in dem Kaltlagerfach den Ventilator ein oder ausschaltet und/oder in seiner Drehzahl verändert und/oder den Volumenstrom der durch den Verdampfer gekühlten Luft in das erste, vorzugsweise in das Kühlkompartiment und/oder in das zweite Kompartiment, vorzugsweise in das Kaltlagerfach vorzugsweise durch Verstellung wenigstens einer Drosselklappe oder dergleichen in dem Kühlluftkanal oder durch Positionsänderung des Ventilators ändert.In a further embodiment of the invention, the at least one control or regulating unit is designed such that it switches on or off depending on the refrigeration demand in the first and / or second compartment, preferably in the Kühlkompartiment and / or in the cold storage compartment fan and / or changed in its speed and / or the volume flow of the air cooled by the evaporator in the first, preferably in the Kühlkompartiment and / or in the second compartment, preferably in the cold storage compartment preferably by adjusting at least one throttle or the like in the cooling air duct or by changing the position of the Fan changes.

So ist es denkbar, dass in dem ersten Kompartiment und/oder in dem zweiten Kompartiment ein oder mehrere Temperaturfühler vorgesehen sind, die die jeweiligen Istwerte der Temperatur erfassen. Diese werden dann mit Sollwerten verglichen und in Abhängigkeit von einer Abweichung zwischen Ist- und Sollwert wird der Kältebedarf bestimmt. Denkbar ist es, das in Abhängigkeit von diesen Abgleich bzw. von dem Kältebedarf die Steuer- oder Regelungseinheit den Ventilator betreibt oder ausschaltet und/oder diesen in seiner Drehzahl und/oder in seiner Position verändert, so dass ein größerer oder kleinerer Volumenstrom dem z.B. Kühlkompartiment oder dem Kaltlagerfach bzw. dem ersten und/oder zweiten Kompartiment zugeführt wird. Denkbar ist es auch, dass ein Drosselelement, wie beispielsweise eine Klappe oder dergleichen geschlossen, geöffnet oder ihrer Position verändert wird, die die Zufuhr von durch den Verdampfer gekühlter Luft in das oder die Kompartimente beeinflusst.Thus, it is conceivable that in the first compartment and / or in the second compartment one or more temperature sensors are provided which detect the respective actual values of the temperature. These are then compared with setpoints and depending on a deviation between the actual and setpoint, the cooling demand is determined. It is conceivable that, depending on this balancing or cooling requirement, the control or regulating unit operates or switches off the fan and / or changes its speed and / or position, so that a larger or smaller volume flow is attributable to e.g. Cooling compartment or the cold storage compartment or the first and / or second compartment is supplied. It is also conceivable that a throttle element, such as a flap or the like is closed, opened or changed its position, which influences the supply of air cooled by the evaporator in the one or more compartments.

In weiterer Ausgestaltung der Erfindung ist zumindest ein Speichermedium, vorzugsweise ein Schwamm, ein Lavagestein oder ein sonstiges zur Aufnahme von Wasser geeignetes Mittel vorgesehen, das geeignet ist, aus dem Tauwasserauffangbehältnis befindliches oder von diesem ablaufendes Wasser aufzunehmen. Dieses Speichermedium kann derart in dem von dem Ventilator geförderten Volumenstrom platziert sein oder platziert werden, dass die Luft durch das in dem Speichermedium befindliche Tauwasser befeuchtet wird. Dabei ist es denkbar, das Speichermedium wahlweise in den Strom der Kaltluft, der dem oder den Kompartimenten zugeführt wird, oder aus diesem heraus zu bewegen oder teilweise in diesen hinein zu bewegen, je nachdem in welchem Umfang eine Befeuchtung der Luft erforderlich ist. So ist es denkbar, dass ein oder mehrere Feuchtigkeitssensoren vorgesehen sind, beispielsweise in dem Kaltlagerfach und/oder in dem Kühlkompartiment bzw. in dem ersten und/oder zweiten Kompartiment und dass bei einer Feststellung, dass die Luftfeuchtigkeit geändert werden muss das Speichermedium derart bzw. weiter in den bzw. aus dem Kaltluftstrom bewegt wird, so dass eine stärkere oder weniger starke Befeuchtung der Luft stattfindet. Die Positionierung des Speichermediums kann somit von dem Bedarf an Befeuchtung abhängen.In a further embodiment of the invention, at least one storage medium, preferably a sponge, a lava rock or another suitable for receiving water means is provided which is adapted to receive from the condensation water container or running off this water. This storage medium may be placed or placed in the volumetric flow delivered by the fan in such a way that the air through the in the storage medium moistened water is moistened. It is conceivable, the storage medium either in the flow of cold air, which is supplied to the one or more compartments, or to move out of this or partially into it, depending on the extent to which a humidification of the air is required. Thus, it is conceivable that one or more moisture sensors are provided, for example in the cold storage compartment and / or in the cooling compartment or in the first and / or second compartment and that in a statement that the humidity must be changed, the storage medium such or is further moved into or out of the cold air flow, so that a stronger or less strong humidification of the air takes place. The positioning of the storage medium may thus depend on the need for humidification.

Die vorliegende Erfindung betrifft des Weiteren ein Verfahren zum Betreiben eines Kühl- und/oder Gefriergerätes nach einem der Ansprüche 1-13, wobei vorgesehen ist, dass in Abhängigkeit von den Kältebedarf in dem ersten Kompartiment, vorzugsweise in dem Kühlkompartiment und/oder dem zweiten Kompartiment, vorzugsweise in dem Kaltlagerfach der Ventilator ein- oder ausgeschaltet wird und/oder in seiner Drehzahl verändert wird und/oder der Volumenstrom der durch den Verdampfer gekühlten Luft in das erste und/oder in das zweite Kompartiment vorzugsweise durch Verstellung einer Drosselklappe oder dergleichen oder auch durch Positionsänderung des Ventilators geändert wird.The present invention further relates to a method for operating a refrigerator and / or freezer according to any one of claims 1-13, wherein it is provided that depending on the refrigeration demand in the first compartment, preferably in the cooling compartment and / or the second compartment , Preferably in the cold storage compartment of the fan is switched on or off and / or is changed in its speed and / or the volume flow of the air cooled by the evaporator in the first and / or in the second compartment, preferably by adjusting a throttle valve or the like or is changed by changing the position of the fan.

Eine besonders vorteilhafte Ausgestaltung der Erfindung besteht darin, dass in Abhängigkeit von dem Kältebedarf in dem ersten Kompartiment und/oder in dem zweiten Kompartiment eine Positionsänderung des Ventilators vorgenommen wird.A particularly advantageous embodiment of the invention is that depending on the refrigeration demand in the first compartment and / or in the second compartment, a change in position of the fan is made.

Wie bereits oben ausgeführt, kann es sich bei dem ersten Kompartiment beispielsweise um ein Kühlkompartiment oder auch um ein Kaltlagerfach handeln. Dies gilt auch für das zweite Kompartiment. Das erste Kompartiment und das zweite Kompartiment können grundsätzlich durch beliebige Fächer belegt bzw. gebildet werden.As already stated above, the first compartment can be, for example, a refrigeration compartment or also a cold storage compartment. This also applies to the second compartment. The first compartment and the second compartment can basically be occupied or formed by any number of compartments.

Wie oben ausgeführt, besteht eine denkbare Funktionsweise des erfindungsgemäßen Gerätes vorzugsweise darin, dass ein statischer Kühlbetrieb eingestellt wird, indem der Ventilator ausgeschaltet wird, wenn nur das unterhalb der horizontalen Trennplatte befindlichen Kompartiment einen Kältebedarf meldet. Besteht auch oder nur in dem oberhalb der horizontalen Trennplatte befindlichen Kompartiment Kältebedarf, wird der Ventilator eingeschaltet.As stated above, one conceivable mode of operation of the device according to the invention is preferably that a static cooling mode is set, by turning off the fan when only the compartment below the horizontal divider plate reports a refrigeration demand. Is also or only in the compartment located above the horizontal partition cooling demand, the fan is turned on.

Als Nebeneffekt ist eine Reduktion der horizontalen Temperaturdifferenz in dem unterhalb der horizontalen Trennplatte angeordneten Kompartiment zu erwarten, da vorzugsweise vorgesehen ist, dass sich das Tauwasserauffangbehältnis über die gesamte Unterseite oder über einen Großteil der Unterseite der horizontalen Trennplatte erstreckt. Eine Reduktion der horizontalen Temperaturdifferenz drückt sich positiv auf den Normenergieverbrauch aus.As a side effect, a reduction of the horizontal temperature difference in the arranged below the horizontal partition plate compartment is to be expected because it is preferably provided that the condensation collection container extends over the entire bottom or over a large part of the underside of the horizontal partition plate. A reduction of the horizontal temperature difference has a positive effect on the standard energy consumption.

Gegenüber dem eingangs beschriebenen System wird das erste, vorzugsweise das Kühlkompartiment im statischen Betrieb, d.h. bei ausgeschaltetem Ventilator nochmals weniger gekühlt als das Kaltlagerfach bzw. als das Fach, das sich unterhalb der horizontalen Trennplatte befindet. Dadurch ist es möglich, die Temperatur in dem zweiten Kompartiment, insbesondere in dem Kaltlagerfach unabhängiger von der Temperatur in dem ersten Kompartiment, insbesondere in dem Kühlkompartiment, einzustellen.Compared to the system described in the introduction, the first, preferably the cooling compartment in static operation, i. Less cooled than the cold storage compartment or the compartment below the horizontal divider when the fan is off. This makes it possible to adjust the temperature in the second compartment, in particular in the cold storage compartment, more independently of the temperature in the first compartment, in particular in the refrigeration compartment.

Im dynamischen Kühlbetrieb, d.h. bei in Betrieb befindlichem Ventilator ist vorzugsweise vorgesehen, dass eine Teilluftmenge der vom Verdampfer abgekühlten Luft in das erste Kompartiment und eine Teilluftmenge in das zweite Kompartiment gefördert wird. Denkbar ist es jedoch auch, auch im dynamischen Betrieb die Luftführung so einzustellen, dass die Kaltluft nur dem ersten oder auch nur dem zweiten Kompartiment zugeführt wird. Dies kann beispielsweise durch Verschließen entsprechender Öffnungen bzw. eines Kühlluftkanals oder durch Verstellung der Position des Ventilators erreicht werden.In dynamic cooling mode, i. When the fan is in operation, it is preferably provided that a partial air quantity of the air cooled by the evaporator is conveyed into the first compartment and a partial air quantity into the second compartment. However, it is also conceivable to adjust the air flow even in dynamic operation so that the cold air is supplied only to the first or even the second compartment. This can be achieved for example by closing corresponding openings or a cooling air channel or by adjusting the position of the fan.

Verglichen zu dem eingangs beschriebenen System erhöht sich der Volumenstrom, der aufzubauende dynamische Druck reduziert sich. Dies stellt eine bevorzugte Ausgestaltung der Erfindung dar. Dies kommt der Arbeitsweise der kostengünstigen Axialventilatoren entgegen und kann sich durch mögliche niedrigere Drehzahlen im Hinblick auf die Geräuschentwicklung günstig auswirken.Compared to the system described in the introduction, the volume flow increases and the dynamic pressure to be built up is reduced. This is a preferred embodiment of the invention. This is contrary to the operation of the cost-effective axial fans and may have a favorable effect by possible lower speeds in terms of noise.

In einer bevorzugten Ausgestaltung der Erfindung wird dem ersten Kompartiment, vorzugsweise dem Kühlkompartiment die durch den Verdampfer gekühlte Luft von oben zugeführt. Dies bedeutet, dass im oberen Bereich dieses Kompartimentes wenigstens eine Öffnung im Kühlluftkanal vorgesehen ist, durch die die seitens des Verdampfers gekühlte Luft in das Kompartiment eintritt. Durch eine solche Luftführung, bei der die Kaltluft das erste Kompartiment bzw. das Kühlkompartiment von oben nach unten durchströmt, verringert sich die vertikale Typentemperaturdifferenz in diesem Kompartiment.In a preferred embodiment of the invention, the first compartment, preferably the cooling compartment, is supplied with the air cooled by the evaporator from above. This means that at least one opening in the cooling air duct is provided in the upper region of this compartment through which the air cooled by the evaporator enters the compartment. Such an air duct, in which the cold air flows through the first compartment or the cooling compartment from top to bottom, reduces the vertical type temperature difference in this compartment.

Der erfindungsgemäß eingesetzte Ventilator kann auch dazu benutzt werden, die Temperaturen im Kaltlagerfach zu vergleichsmäßigen. Dies bringt Vorteile bei der Ermittlung des Normenergieverbrauchs mit sich. Des Weiteren kann der Ventilator genutzt werden, um das Abtauen zu beschleunigen. Dies reduziert die zyklisch bedingten, zeitlichen Temperaturunterschiede im Bereich des Kaltlagerfaches bzw. im Bereich des unterhalb der horizontalen Trennplatte befindlichen Kompartimentes.The fan used according to the invention can also be used to make the temperatures in the cold storage compartment comparable. This brings advantages in the determination of the standard energy consumption. Furthermore, the fan can be used to accelerate defrosting. This reduces the cyclical, temporal temperature differences in the region of the cold storage compartment or in the region of the compartment below the horizontal separating plate.

Die Ventilatorlagerung kann verstellbar, beispielsweise drehbar oder kippbar sein. Dadurch kann sich der Volumenstrom der Kaltluft einstellen lassen, die dem ersten und/oder dem zweiten Kompartiment zugeführt wird. Vorzugsweise kann durch eine Verstellung des Ventilators eine Änderung der Relation der beiden Kompartimenten zugeführten Kaltluftmenge reguliert bzw. eingestellt werden.The fan bearing can be adjustable, for example, be rotatable or tiltable. As a result, the volume flow of cold air can be adjusted, which is supplied to the first and / or the second compartment. Preferably, by adjusting the fan, a change in the relation of the two compartments supplied amount of cold air can be regulated or adjusted.

Wie oben ausgeführt, kann das Tauwasser über ein Speichermedium abgeleitet werden. Dieses kann in der vom Verdampfer kommenden Luftströmung angeordnet werden, so dass die trockene, vom Verdampfer kommende Luft befeuchtet wird und so insgesamt eine höhere relative Luftfeuchtigkeit zum Beispiel im Bereich des Kaltlagerfaches erzielt wird.As stated above, the condensate can be discharged via a storage medium. This can be arranged in the air flow coming from the evaporator, so that the dry, coming from the evaporator air is humidified and so a total of higher relative humidity, for example, in the field of cold storage compartment is achieved.

An dieser Stelle wird darauf hingewiesen, dass der Begriff "horizontale Trennplatte" nicht derart eng auszulegen ist, dass nur exakt horizontale Trennplatten von der Erfindung umfasst sind. Auch zur Horizontalen geneigte Trennplatten sind von diesem Begriff mitumfasst. Der Begriff "horizontale Trennplatte" bedeutet eine Trennplatte, die ein oberes von einem unteren Kompartiment trennt.It should be noted at this point that the term "horizontal separating plate" should not be interpreted so narrowly that only exactly horizontal separating plates are encompassed by the invention. Also inclined to the horizontal partition plates are included in this term. The term "horizontal separator plate" means a separator plate separating an upper compartment from a lower compartment.

Auch der Begriff "vertikale" Trennplatte" bedeutet nicht, dass diese Trennplatte exakt vertikal angeordnet sein muss. Auch eine Neigung relativ zur Vertikalen ist von der Erfindung mitumfasst.Also, the term "vertical" divider panel "does not mean that this divider panel needs to be positioned exactly vertically, and an inclination relative to the vertical is also encompassed by the invention.

Figur 1 zeigt ein Kühlgerät mit einem Korpus 100 und mit einer Tür 200. Der Korpus 100 und die Tür 200 umschließen einen gekühlten Innenraum, der durch die horizontale Trennplatte 10 in zwei Teilbereiche unterteilt ist. Oberhalb der horizontalen Trennplatte 10 befindet sich das Kühlkompartiment 20, in dem eine mittlere Kühlraumtemperatur gemäß EN ISO 15502 von ca. +4 °C bis +9 °C herrscht. Unterhalb der horizontalen Trennplatte 10 befindet sich das Kaltlagerfach 30, in dem eine Temperatur innerhalb von Grenztemperaturen von -2 °C bis +3 °C herrscht. FIG. 1 shows a refrigerator with a body 100 and with a door 200. The body 100 and the door 200 enclose a cooled interior, which is divided by the horizontal partition plate 10 into two sections. Above the horizontal separating plate 10 is the cooling compartment 20, in which an average cold room temperature according to EN ISO 15502 of about +4 ° C to +9 ° C prevails. Below the horizontal partition plate 10 is the cold storage compartment 30, in which a temperature within limit temperatures of -2 ° C to +3 ° C prevails.

Wie dies aus Figur 1 ersichtlich ist, besteht die horizontale Trennplatte 10 aus einer oberen plattenförmigen horizontalen Ablage 12, die den Boden des Kühlkompartiments 20 bildet und einem darunter befindlichen horizontal angeordneten Verdampfer 40 sowie aus dem Tauwasserauffangbehältnis 50.Like this FIG. 1 it can be seen, the horizontal partition plate 10 consists of an upper plate-shaped horizontal tray 12, which forms the bottom of the Kühlkompartiments 20 and an underlying horizontally disposed evaporator 40 and from the condensation collection container 50th

Im rückwärtigen Bereich der horizontalen Trennplatte 10 befindet sich der Ventilator 60, der derart betrieben wird, dass er Luft von dem Verdampfer 40 ansaugt und dann in das Kühlkompartiment 20 und/oder in das Kaltlagerfach 30 fördert.In the rear region of the horizontal partition plate 10 is the fan 60, which is operated so that it sucks air from the evaporator 40 and then promotes the cooling compartment 20 and / or in the cold storage compartment 30.

Wie dies aus Figur 1 weiter ersichtlich ist, befindet sich im rückwärtigen Bereich des Kühlkompartimentes 20 eine vertikale Trennplatte 70, die einen Kühlluftkanal 80 abtrennt. Dieser Kühlluftkanal weist eine obere Öffnung 82 auf, durch die Luft aus dem Kühlluftkanal 80 in das Kühlkompartiment 20 oben einströmt. Der Kühlluftkanal 80 weist eine untere Einlassöffnung bzw. einen unteren Einlassbereich auf, durch den Luft von dem Ventilator 60 in den Kühlluftkanal 80 gefördert wird, wie dies durch die Pfeile in Figur 1 angedeutet ist.Like this FIG. 1 it can be seen further, is located in the rear region of the cooling compartment 20, a vertical partition plate 70 which separates a cooling air duct 80. This cooling air duct has an upper opening 82, through which air flows from the cooling air duct 80 into the cooling compartment 20 at the top. The cooling air duct 80 has a lower inlet opening and a lower inlet area, respectively, through which air is conveyed from the fan 60 into the cooling air channel 80, as indicated by the arrows in FIG FIG. 1 is indicated.

Des Weiteren ist eine Öffnung zwischen dem Ventilator 60 und dem Kaltlagerfach 30 vorgesehen, durch die durch den Ventilator 60 geförderte Luft in das Kaltlagerfach 30 gelangt. Diese Lufteinführung in das Kaltlagerfach kann unmittelbar erfolgen, indem die Luft durch eine Öffnung in der horizontalen Trennplatte 10 in das Kaltlagerfach 30 strömt. Auch ist es denkbar, dass in dem rückwärtigen Bereich des Kaltlagerfaches 30 ebenfalls ein Kühlluftkanal angeordnet ist, der eine oder mehrere Öffnungen aufweist, durch die Luft in das Kaltlagerfach 30 strömt.Furthermore, an opening is provided between the fan 60 and the cold storage compartment 30, through which air conveyed by the fan 60 passes into the cold storage compartment 30. This introduction of air into the cold storage compartment can take place immediately by the air flowing through an opening in the horizontal partition plate 10 into the cold storage compartment 30. It is also conceivable that in the rear region of the cold storage compartment 30, a cooling air duct is also arranged, which has one or more openings through which air flows into the cold storage compartment 30.

Wie dies aus Figur 1 hervorgeht, wird im dynamischen Betrieb des Gerätes Luft von dem Ventilator 60 nach oben und nach unten, d.h. einerseits in den Kühlluftkanal 80 und andererseits in das Kaltlagerfach 30 eingeführt. Diese Luft wird von dem Verdampfer 40 gekühlt und von dem Ventilator 60 gefördert.Like this FIG. 1 As can be seen, in the dynamic operation of the device, air is introduced from the fan 60 upwards and downwards, ie, on the one hand into the cooling air duct 80 and on the other hand into the cold storage compartment 30. This air is cooled by the evaporator 40 and conveyed by the fan 60.

Wie dies aus Figur 1 ersichtlich ist, wird die Luft jeweils im rückwärtigen Bereich des Kühlkompartiments 20 und des Kaltlagerfachs 30 entlang geführt bzw. in diese Kompartiment eingeführt. Die Luft durchströmt dann die Kompartimente und gelangt nach der Durchströmung von oben nach unten bezüglich des Kühlkompartimentes 20 bzw. nach der Durchströmung von unten nach oben des Kaltlagerfachs 30 wieder zurück zu dem Verdampfer 40, so dass bezogen auf jedes der Kompartimente eine Kreislaufströmung entsteht.Like this FIG. 1 is visible, the air is guided in each case in the rear region of the cooling compartment 20 and the cold storage compartment 30 along or introduced into this compartment. The air then flows through the compartments and, after passing through from top to bottom with respect to the cooling compartment 20 or after the flow from bottom to top of the cold storage compartment 30, returns to the evaporator 40, so that a circulation flow occurs relative to each of the compartments.

Im statischen Betrieb, d.h. bei ausgeschaltetem Ventilator 60 gelangt die gekühlte Luft aufgrund ihrer hohen Dichte von dem Verdampfer 40 in das Kaltlagerfach 30. Sie durchströmt dabei das luftdurchlässige Tauwasserauffangbehältnis 50. Die aufgrund der höheren Dichte gemäß der Pfeile in Figur 2 nach unten fallende Luft bewirkt ein vertikal nach oben Strömen der im Kaltlagerfach 30 befindlichen, vergleichweise warmen und feuchten Luft. Diese durchströmt das luftdurchlässige Tauwasserauffangbehältnis 50 und gelangt zu dem Verdampfer 40, an dem die Luftfeuchtigkeit auskondensiert. Das in dem Tauwasserauffangbehältnis 50 befindliche Tauwasser kann durch ein Speichermedium, wie z.B. durch einen Schwamm aufgenommen werden oder in sonstiger geeigneter Weise abgeführt werden.During static operation, ie with the fan 60 switched off, the cooled air, due to its high density, passes from the evaporator 40 into the cold storage compartment 30. It flows through the air-permeable condensation-collecting container 50 FIG. 2 Down falling air causes a vertical upward flow of the cold storage compartment 30 located, comparatively warm and humid air. This flows through the air-permeable condensate collection container 50 and reaches the evaporator 40, where the humidity condenses out. The located in the condensation collection container 50 Dew water can be absorbed by a storage medium, such as by a sponge, or removed in any other suitable manner.
