Abstract
Description
Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem Kältemittelkreislauf, der wenigstens einen in mittlerer Höhe des Gerätes angeordneten Kompressor zur Verdichtung von Kältemittel sowie wenigstens einen Verdampfer zur Verdampfung des Kältemittels aufweist.The present invention relates to a refrigerator and / or freezer with at least one refrigerant circuit, which has at least one arranged at a medium height of the device compressor for compressing refrigerant and at least one evaporator for evaporating the refrigerant.
Bei vielen Kühl- und/oder Gefriergeräten bildet der Kompressor einen Bestandteil des Kältemittelkreislaufes und hat die Aufgabe, durch Wärmezufuhr im Verdampfer verdampftes Kühlmittel zu verdichten und dem Verflüssiger zuzuführen, in dem es durch Wärmeabgabe an die Umgebung wieder in den flüssigen Zustand übergeht. Bei herkömmlichen Kühl- und/oder Gefriergeräten befindet sich der Kompressor in einem unteren Bereich des Gerätes, was den Nachteil hat, dass ein Teil des dort befindlichen Gefrierteils oder sonstigen Kompartiments des Gerätes nur mit verringerter Tiefe ausgeführt werden kann. Aus dem Stand der Technik sind ferner Kühl- bzw. Gefriergeräte bekannt, bei denen der Kompressor oben und/oder in mittlerer Höhe des Gerätes angeordnet ist.In many refrigerators and / or freezers, the compressor forms part of the refrigerant circuit and has the task to compress by evaporation of heat in the evaporator vaporized coolant and fed to the condenser, in which it passes through heat to the environment back to the liquid state. In conventional refrigerators and / or freezers, the compressor is located in a lower portion of the device, which has the disadvantage that a portion of the freezer compartment or other compartment of the device located there can only be designed with reduced depth. Cooling or freezing devices are also known from the prior art, in which the compressor is arranged above and / or in the middle height of the device.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Kühl- und/oder Gefriergerät der eingangs genannten Art weiter zu verbessern.The object of the present invention is to further improve a refrigerator and / or freezer of the type mentioned.
Diese Aufgabe wird ausgehend von einem Kühl- und/oder Gefriergerät gemäß dem Oberbegriff des Anspruchs 1 dadurch gelöst, dass das Gerät ein Gefrierteil aufweist und dass der das Gefrierteil kühlende Verdampfer als No-Frost-Verdampfer ausgeführt ist. Bei derartigen No-Frost-Verdampfern handelt es sich um Einheiten, durch die vorzugsweise mittels Ventilatoren Luft geführt wird. Die auf diese Weise gekühlte Luft wird sodann dem zu kühlenden Raum zugeführt bzw. in dem zu kühlenden Raum verteilt. Beim Abkühlen der Luft schlägt sich die vorhandene Luftfeuchtigkeit am Verdampfer nieder. Eine Heizung am oder im Verdampfer sorgt dafür, dass das entstehende Eis bei Bedarf oder in regelmäßigen Abständen abgetaut wird. Ein Vorteil des No-Frost-Gefriergerätes besteht darin, dass ein langwieriger manueller Abtauprozeß entfallen kann. Die Reinigung des Gerätes ist leicht möglich, da im Gefrierraum kein oder kaum Eis anfällt.This object is achieved starting from a refrigerator and / or freezer according to the preamble of claim 1, characterized in that the device has a Gefrierteil and that the freezer cooling the evaporator is designed as a no-frost evaporator. Such no-frost evaporators are units through which air is preferably passed through fans. The air cooled in this way is then supplied to the space to be cooled or distributed in the space to be cooled. When cooling the air, the existing humidity on the evaporator is reflected. A heater on or in the evaporator ensures that the resulting ice is thawed as needed or at regular intervals. An advantage of the no-frost freezer is that a lengthy manual defrosting process can be eliminated. The cleaning of the device is easily possible because there is no or hardly any ice in the freezer compartment.
Aufgrund der Tatsache, dass sich der Kompressor bei dieser Ausgestaltung der Erfindung in mittlerer Gerätehöhe befindet, besteht die Möglichkeit, ein unten angeordnetes Gefrierteil ganz über die volle Tiefe des Gerätes auszuführen und in dem Gefrierteil den genannten No-Frost-Verdampfer anzuordnen.Due to the fact that the compressor is in this embodiment of the invention in medium height, it is possible to run a freezer arranged below completely over the full depth of the device and to arrange in the freezer compartment said no-frost evaporator.
Die Erfindung betrifft ferner ein Kühl- und/oder Gefriergerät mit wenigstens einem Kältemittelkreislauf, der wenigstens einen Kompressor zur Verdichtung von Kältemittel sowie wenigstens einen Verdampfer zur Verdampfung des Kältemittels aufweist. Das Gerät weist ferner einen in wenigstens zwei Kompartimente unterteilten Kühl- bzw. Gefrierraum zur Aufnahme des zu kühlenden Gutes bzw. des Gefriergutes auf, wobei der Kompressor zwischen zwei der Kompartimente angeordnet ist. Erfindungsgemäß ist vorgesehen, dass es sich bei wenigstens einem der Kompartimente um ein Gefrierteil handelt und dass der das Gefrierteil kühlende Verdampfer als No-Frost-Verdampfer ausgeführt ist.The invention further relates to a refrigerator and / or freezer with at least one refrigerant circuit having at least one compressor for compressing refrigerant and at least one evaporator for evaporating the refrigerant. The apparatus further comprises a divided into at least two compartments cooling or freezing space for receiving the goods to be cooled or the frozen food, wherein the compressor is disposed between two of the compartments. According to the invention, it is provided that at least one of the compartments is a freezer and that the evaporator cooling the freezer is designed as a no-frost evaporator.
Vorzugsweise ist vorgesehen, dass der Kompressor oberhalb des Gefrierteils angeordnet ist.It is preferably provided that the compressor is arranged above the freezer part.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Verdampfer in dem Gefrierteil vertikal oder horizontal angeordnet ist. Denkbar ist beispielsweise, dass in dem Gefrierteil eine, zwei oder mehr als zwei Schubladen angeordnet sind, und dass in dem Bereich hinter den Schubladen der No-Frost-Verdampfer vertikal angeordnet ist. Dieser kann sich je nach Bedarf über die gesamte Höhe des Gefrierteils oder auch nur über einen Teilbereich erstrecken. Grundsätzlich ist es ebenfalls denkbar, den No-Frost-Verdampfer nicht unmittelbar im Gefrierteil, sondern in einem davon abgegrenzten Kompartiment unterzubringen, das mit dem Gefrierteil in Strömungsverbindung steht, so dass die Kaltluft dem Gefrierteil zugeführt werden kann.In a preferred embodiment of the invention it is provided that the evaporator is arranged vertically or horizontally in the freezer compartment. It is conceivable, for example, that one, two or more than two drawers are arranged in the freezer compartment, and that in the area behind the drawers the no-frost evaporator is arranged vertically. This can extend as needed over the entire height of the freezer or even over a partial area. In principle, it is also conceivable to accommodate the no-frost evaporator not directly in the freezer compartment but in a compartment delimited therefrom, which is in flow communication with the freezer compartment, so that the cold air can be supplied to the freezer compartment.
Auch eine horizontale Anordnung des Verdampfers ist denkbar, bei der sich der Verdampfer vorzugsweise an der Decke des Gefrierteils befindet. Das Gefrierteil erhält dadurch eine größere nutzbare Tiefe.A horizontal arrangement of the evaporator is conceivable in which the evaporator is preferably located on the ceiling of the freezer. The freezer gets a greater usable depth.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass in dem Gefrierteil eine, zwei oder mehr als zwei Schubladen aufgenommen sind, wobei die zwei oder mehr als zwei Schubladen dieselbe Tiefe aufweisen können. Selbstverständlich ist von der Erfindung auch eine Ausführung umfasst, bei der die zwei oder mehr als zwei Schubladen eine voneinander abweichende Tiefe aufweisen.In a further embodiment of the invention it is provided that in the freezer part, one, two or more than two drawers are accommodated, wherein the two or more than two drawers can have the same depth. Of course, the invention also includes an embodiment in which the two or more than two drawers have a different depth from each other.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Kompressor derart angeordnet, dass er gegenüber der Gerätefront zurückversetzt ist und dass in dem Bereich vor dem Kompressor ein Kompartiment angeordnet ist. Denkbar ist ferner, dass der Kompressor gegenüber der Gerätemitte zur Seite versetzt ist und dass in dem Bereich neben dem Kompressor ein Kompartiment angeordnet ist. Bei diesem Kompartiment bzw. diesen Kompartimenten kann es sich beispielsweise um ein oder mehrere Kaltlagerfächer oder um ein Gemüsefach oder auch um normalen Kühlraum handeln.According to a preferred embodiment of the invention, the compressor is arranged such that it is set back relative to the front of the device and that in the area in front of the compressor, a compartment is arranged. It is also conceivable that the compressor is offset from the center of the device to the side and that in the area next to the compressor, a compartment is arranged. In this Compartment or these compartments may be, for example, one or more cold storage compartments or a vegetable compartment or normal cold storage.
In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass das Gerät wenigstens ein Kühlteil und wenigstens ein Gefrierteil aufweist. Dabei kann das Kühlteil beispielsweise oben und das Gefrierteil beispielsweise unten angeordnet sein. Grundsätzlich sind auch davon abweichende Ausgestaltungen denkbar.In a further embodiment of the invention, it is provided that the device has at least one cooling part and at least one freezer part. In this case, the cooling part, for example, above and the freezer compartment, for example, be arranged below. In principle, deviating configurations are also conceivable.
Unterhalb des Gerätes kann sich ein Behältnis zur Aufnahme von Tauwasser, das heißt eine Tauwasserschale bzw. eine Verdunstungsschale befinden, die Tauwasser aufnimmt, das im Betrieb des Gerätes bzw. beim Abtauen eines oder mehrerer Kompartimente des Gerätes anfällt.Below the device, a container for receiving condensation water, that is a thawing shell or an evaporation tray can be located, which receives condensation, which accumulates during operation of the device or defrosting one or more compartments of the device.
In einer weiteren Ausgestaltung der Erfindung ist ein von Luft durchströmter Kanal vorgesehen, der sich zum Teil unterhalb und zum Teil hinter dem Gerät erstreckt. Dabei kann der Kanal einen horizontalen, unterhalb des Gerätes befindlichen Abschnitt aufweisen, der über eine an der Frontseite des Gerätes angeordnete Einlaßöffnung verfügt. Der Kanal kann des Weiteren einen vertikalen, hinter dem Gerät verlaufenden Abschnitt aufweisen, der über eine oben angeordnete Auslaßöffnung verfügt.In a further embodiment of the invention, a channel through which air flows is provided, which extends partly below and partly behind the device. In this case, the channel may have a horizontal, located below the device section which has an arranged on the front side of the device inlet port. The channel may further comprise a vertical portion extending behind the device and having an outlet opening disposed at the top.
Vorzugsweise ist in dem genannten Kanal die wenigstens eine Verdunstungsschale sowie wenigstens ein Verflüssiger des Kältemittelkreislaufes angeordnet. Die über die Verdunstungsschale strömende Luft nimmt Feuchtigkeit auf und wird schließlich beim Umströmen des Verflüssigers erwärmt, bevor sie den genannten Kanal wieder verläßt und in die Raumluft strömt. Auch ist eine Anordnung denkbar, bei der die Luft zunächst am Verflüssiger erwärmt wird und sodann an der Verdunstungsschale vorbeigeführt wird.Preferably, in the said channel, the at least one evaporation tray and at least one condenser of the refrigerant circuit is arranged. The air flowing through the evaporation tray absorbs moisture and is finally heated during the flow around the condenser, before it leaves the said channel again and flows into the room air. An arrangement is also conceivable in which the air is first heated at the condenser and then passed past the evaporation tray.
