Abstract

The domestic refrigerator deep freezer evaporator has a relatively simple de-icer, ensuring long operation periods between de-icing. The de-icing of the cover of the evaporator is carried out outside the freezer. The evaporator is divided into deep freezing and ordinary refrigerating sections by a capillary tube (3). The evaporator has a cover (4) of good thermal conductivity which is removed from the deep freezer compartment for de-icing. The capillary ensures continued operation and temp. maintenance.

Description

Vorrichtung zum vereinfachten Abtauen eines TiefkühlverdampfersDevice for simplified defrosting of a deep-freeze evaporator

Die Erfindung betrifft eine Vorrichtung zum vereinfachten Abtauen eines Tiefkiihlverdampfen in einem Haushaltskühlgerät, insbesondere zum Abtauen oines Gefrierteilverdampfers.The invention relates to a device for simplified defrosting a deep-freeze evaporation in a household refrigerator, especially for defrosting o a freezer compartment evaporator.

In bekannten KühLschränken mit Gefrierfächern muß nach einei gewissen Betriebsdauer der Verdampfer von dem während der Betriebszeit angefallenen mehr oder weniger gleichmäßig über den ganzen Verdampfer verteilten Reif befreit werden. Zu diesem Zweck muß das Kiihlfach entleert und müssen die von Reif befallenen Tei Je über den Gefrierpunkt erwärmt werden. Erschwerend wirkt sich hier der Umstand aus, daß während des Abtausvorganges die Gefrierkost so gelagert werden muß, daß keine unzulässige Temperaturerhöhung eintritt.In known refrigerators with freezer compartments, there is a certain amount of need The operating time of the evaporator is more than that accumulated during the operating time or frost, which is less evenly distributed over the entire evaporator. For this purpose, the refrigerator compartment must be emptied and the parts affected by frost must be removed Each to be heated above freezing point. The situation is aggravating here from that during the defrosting process the frozen food must be stored in such a way that no impermissible temperature increase occurs.

Die vorliegende Erfindung hat die Aufgabe, die Betriebsdauer zwischen den Abtauperioden wesentlich zu verlängern.The present invention aims to reduce the operating time between to significantly extend the defrosting periods.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 genannten Merkmale gelöst.This object is achieved according to the invention by the features in the characterizing part of the claim 1 mentioned features solved.

In weiterer Ausbildung der Erfindung wird der Verdampfer durch Einsatz eines Zwischenkapillarrohres in zwei Temperaturzonen geteilt.In a further embodiment of the invention, the evaporator is through use an intermediate capillary tube divided into two temperature zones.

Der im Tiefkühlteil liegende Verdampferabschnitt (hier ist der stärkste Reifanfall) wird ganz oder teilweise über ein Zwischenkapillarrohr mit Kältemittel versorgt und durch eine metallische, gut wärmeleitende Klammer (Abtaureiter) abgedeckt. Dns eingesetzte Zwischenkapillarrohr bewirkt, daß der nachfolgende Verdampferabschnitt die kälteste Temperatur im Verdampferkreislauf annimmt. An der mit gutem Wärmekontakt aufsitzenden Klammer wird infolge der tiefen Temperatur und der Lage die Reifbildung bevorzugt stattfinden. Sobald die Klammer eine gewisse Reifschicht aufweist, wird sie vom Verdampfer gelöst und aus dem Gerät entfernt. Die eingelagerte Ware bleibt an ihrem Lagerplatz und die Kälteanlage arbeitet in normnler Funktion weiter. Die bereifte Klammer kann nun separat abgetaut werden, z.B. kann der Vorgang im Spülbecken unter Verwendung von fließendem Kalt- oder Warmwasser beschleunigt werden. Die -eisfreie Klammer wird dann wieder an ihren Platz gebracht. Dieser Abtauvorgang kann einige Male wiederholt werden, bis eine allgemeine Verdampferabtauung und Reinigung erforderlich wird, so dan für den Betreiber eine wesentliche Uedienungserleichterung zu verzeichnen ist.The evaporator section located in the freezer compartment (here is the strongest Frost) is wholly or partially via an intermediate capillary tube with refrigerant supplied and covered by a metal clamp (defrost ladder) that conducts heat well. The inserted intermediate capillary tube causes the subsequent evaporator section assumes the coldest temperature in the evaporator circuit. On the one with good thermal contact Due to the low temperature and the location, the brace that is seated causes frost to form take place preferentially. As soon as the clip has a certain layer of frost, will detached from the vaporizer and removed from the device. The stored goods remain at their storage location and the refrigeration system continues to work in its normal function. the Frosted clamps can now be defrosted separately, e.g. the process in the sink be accelerated using running cold or warm water. The ice-free The clip is then put back into place. This defrosting process can do a number of things Repeat times until a general evaporator defrost and cleaning is required becomes, then for the operator to record a significant easing of service is.

Die Erfindung wird im folgenden anhand der Zeichnung an einem Ausführungsbeispiel erläutert: Die Abbildung zeigt schematisch einen Verdampfer für zwei Temperaturbereiche.The invention is illustrated below with reference to the drawing using an exemplary embodiment explained: The figure shows a schematic of an evaporator for two temperature ranges.

Der obere Teil 1 des Verdampfers bildet den Tiefkühlteil, während der untere Teil zum Kühlen eines Normalkühlfaches dienen kann Das eingesetzte Zwichonkapillarrohr 3 bewirkt, daß der nachfolgende Verdampferabschnitt eine kältere Temperatur annimmt, als der vorang-ehende Abschnitt. Zum Schutz gegen Reifbildung auf dem Verdampferteil selbst wird eine Abtauklammer 4 auf die Tiefkühlverdampferfläche aufgeschoben, so daß eine Reifbildung bevorzugt auf der Abtauklammer stattfinden kann.The upper part 1 of the evaporator forms the freezer part while the lower part can be used to cool a normal cooling compartment 3 causes the following evaporator section to assume a colder temperature, than the previous section. To protect against frost formation on the evaporator part even a defrosting clip 4 is pushed onto the freezer evaporator surface, see above that a frost formation can preferably take place on the defrost bracket.

Die Abtauklammer ist von der Verdampferplatine jederzeit leicht lösbar. Sie wird vorteilhaft aus einer gut wärmeleitenden Metallklammer gebildet, die die Verdampferplatine mindestens zum Toil abdeckt und aie dadurch vor einet Reifbefall schützt.The defrost bracket can be easily removed from the evaporator board at any time. It is advantageously formed from a highly thermally conductive metal clip that the Evaporator board covers at least the toilet and aie before a frost infestation protects.
