Description

Die Erfindung betrifft ein Kühl- und/oder Gefriergerät nach dem Oberbegriff des Patentanspruchs 1. Ein solches Gerät ist, z.B., aus der US-A-2 604 760 bekannt.The invention relates to a refrigerator and / or freezer according to the Preamble of claim 1. Such a device is, for example, from the US-A-2 604 760.

Kühl- und Gefriergeräte sowie Kühl-Gefrierkombinationen bestehen aus einem mit einer oder mehreren Türen oder Deckeln versehenen Innenraum. Die Oberflächen des Innenraums werden über eine intermittierend arbeitende Kälteeinrichtung, beispielsweise ein Kompressor-Kühlsystem gekühlt, um die in dem Kühl- und Gefriergerät bzw. der Kühl-Gefrierkombination aufbewahrten Waren auf eine gewünschte tiefe Temperatur zu bringen bzw. auf dieser zu halten.Refrigerators and freezers as well as fridge-freezers exist one with one or more doors or lids Inner space. The surfaces of the interior are intermittent working refrigeration device, for example a compressor cooling system chilled to those in the refrigerator and freezer or the fridge-freezer combination to a desired bring or maintain low temperature.

Während des Kühlvorganges werden die Temperaturen im geschlossenen Innenraum abgesenkt, wodurch der Druck der Luft im Innenraum gegenüber dem Druck der Umgebungsatmosphäre sinkt. Aufgrund dieser Druckdifferenz strömt unkontrolliert Umgebungsluft über feinste Undichtigkeiten in den Innenraum, so daß die Druckdifferenz mit der Zeit ausgeglichen wird. Mit der vergleichsweise wärmeren Umgebungsluft wird Feuchtigkeit in den Innenraum transportiert, die sich aufgrund des tieferen Taupunkts an den kalten Oberflächen des Innenraums, beispielsweise am Verdampfer niederschlägt. In einem Gefriergerät gefriert dieser Niederschlag aufgrund der im Innenraum herrschenden tiefen Temperaturen. During the cooling process, the temperatures are closed Interior lowered, reducing the pressure of the air in the interior compared to the pressure of the surrounding atmosphere. Based on these Pressure difference flows uncontrolled ambient air over the finest Leaks in the interior, so that the pressure difference is balanced over time. With the comparatively warmer Ambient air transports moisture into the interior, due to the lower dew point on the cold surfaces of the interior, for example on the evaporator. This precipitate freezes in a freezer due to the low temperatures prevailing in the interior.

Ein weiteres Problem bei Gefriergeräten und in geringerem Maße auch bei Kühlgeräten ergibt sich durch den sich nach jeder Tür- bzw. Deckelöffnung einstellenden Unterdruck im Innenraum des Gerätes. Dieser Unterdruck resultiert daraus, daß bei jeder Geräteöffnung warme Luft in den Innenraum gelangt, die nach Schließen des Gerätes stark unterkühlt wird und somit ihr Volumen verringert. Hierdurch bildet sich ein Unterdruck, der den Deckel bzw. die Tür mit ihrer Dichtung an das Gehäuse saugt. Je nach Dichtigkeit ist nun ohne mechanische Hilfsmittel oder sonstige Vorrichtungen zur Herstellung eines Druckausgleichs das Gerät für eine bestimmte Zeit nicht mehr zu öffnen. Dieser Zeitraum hängt nun davon ab, wie dicht das Gerät ist. Durch die bereits zuvor erwähnten feinen Undichtigkeiten in den Dichtungen bzw. am Gehäuse erfolgt wieder der Druckausgleich mit der Umgebungsatmosphäre. Nach entsprechendem Abbau des Druckunterschieds zwischen Innenraum und Umgebungsatmosphäre läßt sich die Tür wieder öffnen.Another problem with freezers and to a lesser extent cooling devices also result from the fact that after each door or vacuum opening in the interior of the device. This negative pressure results from the fact that every time the device is opened warm air enters the interior after closing of the device is strongly supercooled and thus its volume is reduced. This creates a negative pressure, which the door with its seal sucks on the housing. Depending on the tightness is now without mechanical aids or other devices the device for a pressure equalization no longer open at certain times. This period now depends depends on how tight the device is. By the ones already mentioned fine leaks in the seals or on the housing the pressure is equalized again with the ambient atmosphere. After reducing the pressure difference between the interior accordingly and the surrounding atmosphere can be opened again.

Nach dem Stand der Technik gemäß der US-A-2 604 760 muß die Silica GelSchüttung, die als Trocknungsmittel dient, nachdem sie die Feuchtigkeit der einströmenden Luft aufgenommen hat, durch ein in der Verbindungsöffnung vorgesehenes Heizelement regeneriert werden. Um die angesaugte Luft, die ja im Kühlschrank heruntergekühlt werden soll, nicht unnötig aufzuheizen und damit die Kühlleistung des Kühlgerätes herunterzusetzen, wird entsprechend der US-A-2 604 760 das Heizelement nur dann aktiviert, wenn der Kompressor ausgeschaltet ist. Dies bedingt eine vergleichsweise komplizierte Schaltung des Heizelementes, das zur Regenerierung des Silica Gels dient. Darüber hinaus wird auch bei dieser Lösung das Silica Gel durch eine externe Wärmequelle aufgeheizt. Diese Wärme nimmt die über das regenerierte aber aufgeheizte Silica Gel einströmende Luft auf und transportiert sie in den Innenraum des Kühlgerätes, der ja gerade heruntergekühlt werden soll.According to the state of the art according to US-A-2 604 760, the silica gel bed, which serves as a desiccant after it has the moisture flowing in Has taken up air, regenerated by a heating element provided in the connection opening become. For the air drawn in, which is supposed to be cooled down in the refrigerator, not heating up unnecessarily and thus reducing the cooling capacity of the cooling device, according to US-A-2 604 760, the heating element is only activated when the compressor is switched off. This requires a comparatively complicated circuit of the heating element used to regenerate the silica gel. Furthermore With this solution, the silica gel is also heated by an external heat source. This heat is absorbed by the inflowing but heated silica gel Air and transports it into the interior of the refrigerator, yes just to be cooled down.

Aufgabe der Erfindung ist es, ausgehend von der US-A-2 604 760 ein Kühl- und/oder Gefriergerät zu schaffen, das einen möglichst einfachen Aufbau aufweist und andererseits eine gute Kühlleistung gewährleistet, ohne daß der Innenraum des Gerätes zu stark vereist.The object of the invention is, based on US-A-2 604 760, a refrigerator and / or freezer to create that has the simplest possible structure and on the other hand good cooling performance guaranteed without the interior of the device icing up too much.

Erfindungsgemäß wird diese Aufgabe ausgehend von einem gattungsgemäßen Kühl- und/oder Gefriergerät durch die Merkmale des kennzeichnenden Teils des Hauptanspruchs gelöst. Demnach wird eine Verbindungsöffnung zwischen dem Innenraum des Gerätes mit der Umgebungsatmosphäre geschaffen. Durch diese Öffnung kann gezielt der Druckausgleich stattfinden. Zusätzlich wird die durch die Verbindungsöffnung ausgetauschte Luft erfindungsgemäß auf einen gewünschten Trocknungsgrad eingestellt. Hierzu wird innerhalb der Verbindungsöffnung eine Lufttrocknung durchgeführt. According to the invention, this task is based on a generic Refrigerator and / or freezer by the features of the characteristic Part of the main claim solved. Accordingly, one Connection opening between the interior of the device with the Ambient atmosphere created. Through this opening can be targeted the pressure equalization take place. In addition, the Connection opening exchanged air according to the invention on a desired degree of dryness. This is done within air drying is carried out at the connection opening.

Diese Lufttrocknung erfolgt dadurch, daß in der Verbindungsöffnung ein regenerierbares Trocknungsmittel, beispielsweise Molekularsieb, angeordnet ist. Während der Kompressorlaufzeit, d.h. während der Kühlphase, in welcher im Geräteinnenraum ein Unterdruck erzeugt wird, wird die einströmende Umgebungsluft getrocknet. Die in ihr enthaltene Feuchtigkeit wird beispielsweise vom Molekularsieb aufgenommen und dort gebunden. Wenn nun der Kompressor stillsteht erwärmt sich die Luft im Geräteinnenraum, so daß im Innenraum ein Überdruck entsteht. Hierdurch kann die trockene kalte Luft nach außen strömen und dem Molekularsieb die Feuchtigkeit entziehen. Die Feuchtigkeit wird nach außen transportiert und wieder an die Außenatmosphäre abgegeben. This air drying takes place in that a regenerable drying agent, for example Molecular sieve is arranged. During the compressor runtime, i.e. during the cooling phase, in which inside the device a negative pressure is generated, the incoming ambient air dried. The moisture it contains will for example, taken up by the molecular sieve and bound there. When the compressor stops, the air inside the device warms up, so that there is an overpressure in the interior. Hereby the dry cold air can flow out and the Molecular sieve removes moisture. The moisture will transported outside and released back into the outside atmosphere.

Das in Fig. 1 dargestellte Gefriergerät 10 nach dem Stand der Technik weist einen kühlbaren Innenraum 12 auf, in welchem das zu kühlende bzw. gefrierende Gut lagerbar ist. Die Kühlung erfolgt durch gekühlte Innenwandungen 14. Die Kühlung der Innenwandungen 14 erfolgt über Wärmetauscherrohre 16, die mit einem hier nicht näher dargestellten Kompressor-Kühlsystem in Verbindung stehen. Der Innenraum 12 kann über einen Deckel 18 verschlossen werden, wobei eine weitgehend dichte Verschließbarkeit über umlaufende Dichtungen 20 sichergestellt ist. Bei diesem Gefriergerät 10 nach dem Stand der Technik erfolgt, wie durch die Pfeile a dargestellt, ein Druckausgleich während des Kühlvorgangs durch Einströmen vergleichsweiser feuchter Umgebungsluft über feine Undichtigkeiten im Dichtungsbereich der Dichtung 20 in den Innenraum 12. Dies ist in Fig. 1 durch entsprechende Pfeile a angedeutet. Umgekehrt entweicht während des Kompressorstillstandes die sich im Innenraum 12 aufwärmende Luft in Pfeilrichtung b in die Umgebung. Aufgrund des unkontrollierten Einströmens von vergleichsweise feuchter Umgebungsluft in den Innenraum während des Kühlzyklus schlägt sich vergleichsweise viel Feuchtigkeit in Form von Eis 22 an den Innenwandungen des Gefriergerätes 10 ab.The freezer 10 shown in FIG. 1 according to the state of the Technology has a coolable interior 12, in which the to be cooled or frozen can be stored well. The cooling takes place through cooled inner walls 14. The cooling of the inner walls 14 takes place via heat exchanger tubes 16, with one here Compressor cooling system not shown in connection stand. The interior 12 can be closed by a cover 18 be, with a largely tight closability over circumferential Seals 20 is ensured. With this freezer 10 takes place according to the prior art, as by the arrows a, a pressure equalization during the cooling process Comparatively moist ambient air flows in via fine Leaks in the sealing area of the seal 20 in the interior 12. This is indicated in Fig. 1 by corresponding arrows a. Conversely, the escapes during the compressor shutdown air warming up in the interior 12 in the direction of arrow b in the Surroundings. Due to the uncontrolled inflow of comparatively moist ambient air into the interior during the Comparatively much moisture is reflected in the cooling cycle Form of ice 22 on the inner walls of the freezer 10.

Die in Fig. 2 dargestellte erfindungsgemäße Ausführungsform betrifft grundsätzlich ein Gefriergerät, das in seinem Aufbau demjenigen nach dem Stand der Technik entspricht. Daher sind hier gleiche Teile mit gleichen Bezugszeichen versehen. Im Unterschied zu dem Gefriergerät 10 nach dem Stand der Technik weist das erfindungsgemäße Gefriergerät gemäß Fig. 2 jedoch eine Verbindungsöffnung 24 zwischen dem Innenraum 12 und der Umgebungsatmosphäre auf, die in der hier dargestellten Ausführungsform im Deckel 18 integriert ist. Innerhalb der Verbindungsöffnung 24 ist eine Molekularsiebschüttung 26 enthalten. Durch die Verbindungsöffnung 24 wird sichergestellt, daß je nach Druckverhältnis zwischen Innenraum 12 und Umgebungsatmosphäre gezielt Luft ausgetauscht werden kann. Während der Kompressorlaufzeit, in welcher sich im Innenraum 12 ein Unterdruck bildet, wird die mehr oder weniger feuchte Umgebungsluft angesaugt. Sie gibt ihre Feuchtigkeit an das Molekularsieb 26 ab und gelangt in einem getrockneten Zustand in den Innenraum 12. Hierbei ist der Taupunkt mittels des Molekularsiebs 26 soweit herabgesetzt, daß ein Niederschlag von Wasser in Form von Eis an den Innenwandungen 14 sicher verhindert wird. Wenn der Kompressor steht, erwärmt sich die Luft im Innenraum 12 und strömt aufgrund des sich dadurch aufbauenden Überdrucks durch die Verbindungsöffnung 24 nach außen. Die sich erwärmende trockene Luft entzieht während des Ausströmens die im Molekularsieb gespeicherte Feuchtigkeit und transportiert sie in die Umgebungsatmosphäre. Die Strömungsrichtung der Luft ist mit Doppelpfeil c in Fig. 2 angedeutet.The embodiment shown in FIG. 2 relates basically a freezer that in structure to the one corresponds to the state of the art. Therefore here Identical parts with the same reference numerals. The difference to the freezer 10 according to the prior art the freezer according to the invention shown in FIG. 2, however, a connection opening 24 between the interior 12 and the ambient atmosphere on, in the embodiment shown here in Lid 18 is integrated. Within the connection opening 24 contains a molecular sieve bed 26. Through the connection opening 24 ensures that depending on the pressure ratio Targeted air is exchanged between the interior 12 and the surrounding atmosphere can be. During the compressor runtime, in which a negative pressure forms in the interior 12, the more or less humid ambient air is sucked in. It releases its moisture from the molecular sieve 26 and arrives in a dried one Condition in the interior 12. Here the dew point is by means of the molecular sieve 26 so far reduced that a precipitate of water in the form of ice on the inner walls 14 safely is prevented. When the compressor stops, it warms up the air in the interior 12 and flows because of this build-up overpressure through the connection opening 24 Outside. The warming dry air drains during the The moisture stored in the molecular sieve and transports them into the surrounding atmosphere. The flow direction the air is indicated by double arrow c in Fig. 2.
