Description

Die Erfindung betrifft eine Vorrichtung zum Gefrieren, Tiefkühlen oder Kühlen von Kühlgut nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for freezing, freezing or cooling refrigerated goods according to the preamble of claim 1.

Bei Gefriergeräten, Tiefkühlgeräten und zum Teil auch Kühlgeräten sowie Kombinationen dieser Geräte bildet sich nach längerer Betriebsdauer Eis an den kälteerzeugenden Flächen des Gerätes. Es sind bereits sogenannte "No-Frost"-Geräte bekannt, bei denen dieses Vereisen wirksam verhindert wird. Derartige Geräte sind allerdings in ihrer Herstellung wesentlich aufwendiger und daher teurer. Während des Betriebs haben diese Geräte auch einen wesentlich höheren Energieverbrauch. Dieser höhere Energieverbrauch ist einerseits hinsichtlich der Umweltverträglichkeit bedenklich. Andererseits sind hiermit höhere Betriebskosten für den Betreiber verbunden. Herkömmliche Geräte, die die zuletzt genannten Nachteile nicht aufweisen, müssen dagegen umständlich manuell abgetaut werden. Dieses Abtauen bedeutet jeweils einen vergleichsweise hohen Aufwand, sowohl bei Haushaltsgeräten für die Hausfrau oder auch bei gewerblichen Geräten für das Wartungspersonal. Die Geräte müssen üblicherweise zum Abtauen außer Betrieb gesetzt werden und die gelagerte Ware muß entnommen werden. Anschließend müssen die kälteerzeugenden Flächen über die Gefriertemperatur erwärmt werden, so daß das Eis abtaut. Das Erwärmen von Flächen wird meist durch Zuführen von Energie beschleunigt, was wiederum Kosten verursacht. Eine Erhöhung der Betriebskosten ist auch dadurch bedingt, daß anschließend das Gerät wieder auf die ursprüngliche niedrige Gefriertemperatur gebracht werden muß.In freezers, freezers and in some cases also refrigerators and combinations of these devices form after a long period of operation ice on the cryogenic surfaces of the device. There are already known so-called "no-frost" devices in which this icing is effectively prevented. However, such devices are much more expensive to manufacture and therefore more expensive. During operation, these devices also have a much higher energy consumption. This higher energy consumption is on the one hand with regard to the environmental impact of concern. On the other hand, this involves higher operating costs for the operator. Conventional devices that do not have the last-mentioned disadvantages, however, have to be laboriously defrosted manually. This defrosting means a relatively high cost, both in household appliances for the housewife or in commercial equipment for maintenance personnel. The devices must usually be set to defrost out of service and the stored goods must be removed. Then you have to the cryogenic surfaces are heated above the freezing temperature so that the ice is defrosted. The heating of surfaces is usually accelerated by supplying energy, which in turn causes costs. An increase in operating costs is also due to the fact that then the device must be brought back to the original low freezing temperature.

Ein Tiefkühlgerät mit den Merkmalen des ersten Teils des Anspruchs 1 ist bereits aus der DE 94 14 828 U1 bekannt.A freezer with the features of the first part of claim 1 is already known from DE 94 14 828 U1.

Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung zum Gefrieren, Tiefkühlen oder Kühlen oder eine Kombination der vorgenannten Vorrichtungen derart weiter zu bilden, daß der Enteisungsvorgang vereinfacht wird.The object of the invention is to provide a generic device for freezing, freezing or cooling or a combination of the aforementioned devices in such a way that the deicing process is simplified.

Die Aufgabe wird durch eine Kombination der Merkmale des Anspruchs 1 gelöst. Demnach ist eine Vorrichtung zum Gefrieren, Tiefkühlen oder Kühlen von Kühlgut in einem durch eine Tür oder eine Klappe abgeschlossenen Raum mit zumindest einer kälteerzeugenden Fläche mit einer wiederholt lösbar mit zumindest Teilen der kälteerzeugenden Fläche verbindbaren und diese dicht abdeckenden Folie versehen. Soweit sich auf der kälteerzeugenden Fläche Eis bildet, wächst dieses auf der kälteerzeugenden Folie, so daß es beim Enteisen ausreicht, die Folie von der kälteerzeugenden Fläche zu lösen und außerhalb des Kühl- und Gefriergerätes das Eis von der Folie zu entfernen.The object is achieved by a combination of the features of claim 1. Accordingly, a device for freezing, freezing or cooling refrigerated goods in a closed by a door or a flap space with at least one cryogenic surface with a repeatedly releasably connected to at least parts of the cryogenic surface and this tightly covering film is provided. As soon as ice forms on the cryogenic surface, it grows on the cryogenic film so that when defrosting it is sufficient to release the film from the cryogenic surface and to remove the ice from the film outside the refrigerator and freezer.

Mit dieser Lösung sind eine Reihe von Vorteilen verbunden. Zum einen muß die Vorrichtung nicht mehr vollständig abgetaut werden. Die Ware muß nur teilweise - nämlich im Randbereich - und dann auch nur kurzzeitig entnommen werden und kann anschließend sofort wieder eingelagert werden. Hierdurch steigt die Temperatur der Ware nur unwesentlich an, so daß sie im Regelfall nicht auftauen wird. Der Kühlraum muß nur zum Entnehmen und Wiedereinbringen der Folie geöffnet werden, so daß hier auch ein Aufwärmen des Kühlraums weitgehend verhindert werden kann. Hierdurch kann für den Reinigungsschritt erheblich Energie eingespart werden. Schließlich ist das Abreinigen des Eises von der Folie, nach dem Entnehmen aus der Vorrichtung wesentlich einfacher. Hier kann einfach unter fließendem warmen Wasser oder durch mechanische Verwindung der Folie das Eis von der Oberfläche der Folie gelöst werden.There are a number of advantages associated with this solution. First, the device must not be completely defrosted. The goods must be removed only partially - namely in the edge area - and then only for a short time and can then be stored again immediately. As a result, the temperature of the goods increases only slightly, so that they will not thaw as a rule. The refrigerator must be opened only for removing and reinserting the film, so that a warm-up of the refrigerator can be largely prevented here. As a result, considerable energy can be saved for the cleaning step. Finally, the cleaning of the ice from the film, after removal from the device much easier. Here, simply under flowing warm water or by mechanical twisting of the film, the ice can be detached from the surface of the film.

Demnach ist die Folie gemäß der Efindung als Magnetfolie ausgebildet, wobei die kälteerzeugende Fläche außen aus ferromagnetischem Material besteht und zumindest teilweise mit ferromagnetischem Material versehen ist.Accordingly, the film according to the invention is designed as a magnetic film, wherein the cryogenic surface is made of ferromagnetic material outside and is at least partially provided with ferromagnetic material.

Bevorzugte Ausführungsformen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.

Darüber hinaus ist der Teil der kälteerzeugenden Fläche mit der lösbaren Folie überzogen, der vorwiegend mit Feuchtigkeit beschlägt.In addition, the part of the cryogenic area is coated with the releasable film, which mainly fogs with moisture.

Ganz besonders vorteilhaft ist die lösbare Folie im Randbereich des als kälteerzeugende Fläche ausgebildeten Innenraums zu der Tür oder Klappe hin angeordnet. Bei dieser Ausführungsvariante ist zum einen gewährleistet, daß die sich vorwiegend mit Feuchtigkeit beschlagenden Bereiche der kälteerzeugenden Fläche im Randbereich zur Tür oder Klappe hin abgedeckt sind. Andererseits ergibt sich der Vorteil, daß beim Entnehmen und Einbringen der Folie nicht unbedingt alle Waren aus dem Kühlraum entfernt werden müssen. Schließlich kann die erfindungsgemäße lösbare Folie als Mehrschichtfolie ausgebildet sein, wobei die Außenfläche durch eine Kunststoffolie gebildet ist, die hydrophobe Eigenschaften aufweist, so daß das Eis nach leichter Erwärmung oder schon durch mechanisches Verwinden der Folie leicht ablösbar ist.The detachable film is very particularly advantageously arranged in the edge region of the interior designed as a cold-generating surface toward the door or flap. In this embodiment, on the one hand, it is ensured that the regions of the cold-generating surface, which fog up predominantly with moisture, are covered in the edge region toward the door or flap. On the other hand, there is the advantage that when removing and introducing the film not necessarily all goods must be removed from the refrigerator. Finally, the releasable film of the invention may be formed as a multilayer film, wherein the outer surface is formed by a plastic film having hydrophobic properties, so that the ice is easily removable after slight heating or by mechanical twisting of the film.

In Figur 1 ist eine an sich herkömmliche Gefriertruhe 10 dargestellt, wobei hier die den Innenraum 12 abdeckende Klappe der Einfachheit halber weggelassen wurde. Die Wandungen des Innenraumes sind in hier nicht näher dargestellter Art und Weise als Verdampferflächen und somit als kälteerzeugende Flächen ausgebildet. Im hier dargestellten Ausführungsbeispiel ist nur der oberste Teil der Innenbehälterwandung, an dem erfahrungsgemäß die stärkste Vereisung auftritt, mit einer wieder lösbaren Folie 14 rundumlaufend versehen. Die hier eingebrachte Folie 14 ist als Magnetfolie gebildet, die auf der Verdampferfläche aus Chrom-Nickelstahl über magnetische Anziehungskraft fest und die Oberfläche dicht abdeckend haftet. Hierdurch wird ein Eindringen der Feuchtigkeit direkt auf die Verdampferfläche verhindert.In Figure 1, a conventional freezer chest 10 is shown, in which case the interior 12 covering the flap has been omitted for the sake of simplicity. The walls of the interior are formed here in a manner not shown manner as evaporator surfaces and thus as cryogenic surfaces. In the embodiment shown here, only the uppermost part of the inner container wall, on which experience has shown the strongest icing, provided with a re-releasable film 14 around the circumference. The introduced here film 14 is formed as a magnetic film which adheres to the evaporator surface of chromium-nickel steel on magnetic attraction and the surface tightly covering. This prevents moisture from penetrating directly onto the evaporator surface.

In Figur 2 ist schematisch dargestellt, wie die Folie an ihrem Rand erfaßt und abgezogen werden kann. Das auf ihr anhaftende Eis kann, wie in Figur 3 dargestellt einfach unter fließendem Wasser abgewaschen werden. Alternativ hierzu kann das Eis auch durch Verwinden der Magnetfolie 14 abgeklopft werden, wobei die Magnetfolie zum leichteren Lösen des Eises mit einer Außenfläche aus einem hydrophoben Kunststoff besteht.In Figure 2 is shown schematically how the film can be detected and removed at its edge. The adhering to it ice can, as shown in Figure 3 simply be washed under running water. Alternatively, the ice can also be tapped by twisting the magnetic foil 14, wherein the magnetic foil for easier release of the ice with an outer surface consists of a hydrophobic plastic.

In Figur 4 ist der Schnitt durch einen Teil der Wandung einer Gefriertruhe dargestellt, wobei 16 hier den oberen Kunststoff-Abdeckrahmen bezeichnet. Die Verdampferfläche ist hier durch eine Innenbehälterwandung 18 aus ferromagnetischem Material gebildet. An der Innbehälterwandung aus ferromagnetischem Material liegen zur Innenseite der Wandung unmittelbar Verdampferrohre 20 an, die als Kältemittelleitungen dienen. Die Verdampferrohre sind mit Isolationsschaum 22 umgeben.In Figure 4, the section through a part of the wall of a freezer is shown, 16 here denoted the upper plastic cover frame. The evaporator surface is formed here by an inner container wall 18 made of ferromagnetic material. At the Innbehälterwandung of ferromagnetic material are directly to the inside of the wall evaporator tubes 20, which serve as refrigerant lines. The evaporator tubes are surrounded with insulating foam 22.

Außen auf der Innenbehälterwandung 18 aus ferrromagnetischem Material ist die lösbar aufgebrachte Magnetfolie 14 aufgebracht. Diese kann aufgrund der Magnetverbindung beliebig oft von der Innenbehälterwandung 18 gelöst werden und wieder mit dieser verbunden werden. Im Randbereich liegt die Magnetfolie 14 flächenbündig in einer Ausnehmung 24 eines am oberen Kunststoff-Abdeckrahmen 16 angespritzten Kunststofformteils 26. Hierdurch werden vorstehende Kanten, die zum Ansatz von Verschmutzungen neigen, vermieden.Externally on the inner container wall 18 made of ferromagnetic material, the releasably applied magnetic film 14 is applied. As a result of the magnetic connection, this can be released as often as desired from the inner container wall 18 and connected to it again. In the edge region, the magnetic film 14 is flush with the surface in a recess 24 of a molded plastic molding 26 on the upper plastic cover frame 16. As a result, protruding edges, which tend to approach soiling, are avoided.
