Description

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einem Gerätekorpus mit einer Innenwand, hinter der ein Kühlelement des Kühlkreises zur Innenraumkühlung angeordnet ist, sowie mit einer im Innenraum des Gerätekorpus der genannten Innenwand des Gerätekorpus vorgeblendeten Abdeckplatte, wobei die Abdeckplatte durch lösbare Befestigungsmittel im Innenraum gehalten und aus dem Innenraum entnehmbar ist, so dass der Innenraum wahlweise mit oder ohne Abdeckplatte nutzbar ist.The present invention relates to a refrigerator and / or freezer with a device body having an inner wall, behind which a cooling element of the cooling circuit is arranged for cooling the interior, and with a vorgeblendeten in the interior of the device body of said inner wall of the device body cover plate, wherein the cover plate by releasable fastening means held in the interior and can be removed from the interior, so that the interior is optionally available with or without cover plate.

Bei Kühlgeräten tritt an der Oberfläche der Innenwand, hinter der der Verdampfer des Kühlkreises angeordnet ist, oftmals das Problem von Reifbildung und Kondensatbildung auf, was zunächst optisch bei hochwertigen Geräten nicht akzeptabel ist. Zudem kann ein Anfrieren der einzukühlenden Waren an der Innenwand auftreten.In refrigerators occurs on the surface of the inner wall, behind which the evaporator of the cooling circuit is arranged, often the problem of frost formation and condensation, which is initially not visually acceptable for high-quality equipment. In addition, a freezing of the goods to be cooled on the inner wall occur.

Es wurde deshalb bereits vorgeschlagen, der Inneren Rückwand des Gerätekorpus, hinter der regelmäßig der Verdampfer des Kühlkreises angeordnet ist, eine separate Abdeckplatte im Innenraum des Kühlgeräts vorzublenden, um die genannten Probleme zu beseitigen. Zwischen dieser vorgeblendeten Abdeckplatte und der eigentlichen Korpusinnenwand verbleibt ein Spalt, so dass die Kondensat- und Reifbildung auf der eigentlichen Innenwandoberfläche zwar weiterhin auftreten kann, jedoch nicht auf die Abdeckplatte übergreift. Die durch diese Lösung erreichten Vorteile werden jedoch durch Platzverlust erkauft, da die vorgeblendete Abdeckplatte das nutzbare Innenraumvolumen reduziert, insbesondere da zwischen der Abdeckplatte und der Korpusinnenwand ein Spalt vorzusehen ist. Dies ist zwar in der Regel akzeptabel, da der Innenraum oftmals nicht gänzlich befüllt wird, jedoch dann ärgerlich, wenn das volle Stauvolumen tatsächlich benötigt wird.It has therefore already been proposed, the inner rear wall of the device body, behind which is arranged regularly the evaporator of the cooling circuit, vorzublenden a separate cover plate in the interior of the refrigerator in order to eliminate the problems mentioned. Between this vorgeblendeten cover plate and the actual carcass inner wall remains a gap, so that the condensation and frost formation on the actual inner wall surface may still occur, but does not overlap on the cover plate. However, the advantages achieved by this solution are paid for by loss of space, since the vorgeblende cover plate reduces the usable interior space, especially as between the cover plate and the body inner wall, a gap is provided. Although this is generally acceptable because the interior is often not completely filled, but then annoying when the full storage volume is actually needed.

Aus der US 5,369,963 ist ein Kühl- und Gefriergerät bekannt, bei dem im Gefrierfach eine Abdeckplatte vor dem rückwärtig angeordneten Verdampfer vorgeblendet ist, die mit lösbaren Befestigungsmitteln befestigt ist.From the US 5,369,963 is a refrigerator and freezer is known in which in the freezer compartment a cover plate is vorgeblendet in front of the rear-mounted evaporator, which is fastened with releasable fastening means.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein verbessertes Kühl- und/oder Gefriergerät der genannten Art zu schaffen, das Nachteile des Standes der Technik vermeidet und letzteren in vorteilhafter Weise weiterbildet. Insbesondere soll das Problem der Reif- und Kondensatbildung auf der inneren Rückwand gelöst werden, wobei dennoch bei Bedarf das maximale Stauvolumen des Geräts zur Verfügung steht.Proceeding from this, the present invention has the object to provide an improved refrigerator and / or freezer of the type mentioned, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner. In particular, the problem of frost and condensation on the inner rear wall to be solved, while still providing the maximum storage volume of the device is available if necessary.

Erfindungsgemäß wird diese Aufgabe durch ein Kühl- und/oder Gefriergerät gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention this object is achieved by a refrigerator and / or freezer according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

Es wird also vorgeschlagen, die Abdeckplatte nicht fest in dem Innenraum des Geräts zu montieren, sondern eine bei Bedarf herausnehmbare Abdeckplatte vorzusehen. Dabei ist die Abdeckplatte durch lösbare Befestigungsmittel im Innenraum gehalten und aus dem Innenraum entnehmbar, so dass der Innenraum wahlweise mit oder ohne Abdeckplatte nutzbar ist. Hierdurch erhält das Gerät ein veränderbares Innenraumvolumen, das durch Herausnehmen der Abdeckplatte bei Bedarf vergrößerbar ist, um den maximal möglichen Stauraum zur Verfügung zu haben. Durch dieses variable Innenraumkonzept kann einerseits das Problem der Kondensat- und Reifbildung auf der Korpusinnenwand beseitigt und dennoch bei Bedarf der maximal mögliche Nutzinhalt zur Verfügung gestellt werden.It is therefore proposed not to mount the cover plate firmly in the interior of the device, but to provide a removable if necessary cover plate. In this case, the cover plate is held by releasable fastening means in the interior and removed from the interior, so that the interior is optionally available with or without cover plate. As a result, the device receives a variable interior volume, which can be increased by removing the cover plate, if necessary, to have the maximum possible storage space available. On the one hand, the problem of condensate and frost formation on the inner wall of the carcass can be eliminated by this variable interior concept and, nevertheless, if required, the maximum possible net volume can be made available.

Erfindungsgemäß besitzt das Kühl- und/oder Gefriergerät eine Steuereinrichtung, die die kältetechnischen Auswirkungen des Herausnehmens bzw. Einsetzens der Abdeckplatte berücksichtigt. Gemäß der Erfindung kann die Steuereinrichtung zumindest einen Betriebsparameter zumindest einer kühltechnisch wirksamen Gerätekomponente verändern je nachdem, ob die Abdeckplatte in dem Innenraum eingesetzt ist oder aus diesem entnommen ist. Die Steuereinrichtung passt den Betrieb der notwendigen Gerätekomponenten an die Anwesenheit bzw. Abwesenheit der Abdeckplatte an.According to the invention, the refrigerator and / or freezer has a control device that takes into account the refrigeration effects of removing or inserting the cover plate.

The controller adjusts the operation of the necessary device components to the presence or absence of the cover plate.

Die Anpassung des Betriebsmodus kann dabei grundsätzlich in verschiedener Art und Weise erfolgen. Vorzugsweise kann die Steuereinrichtung einen Temperaturschaltwert des Kühlaggregats verändern, wenn die Abdeckplatte aus dem Innenraum entnommen wird.The adaptation of the operating mode can basically be done in various ways. Preferably, the control device can change a temperature switching value of the cooling unit when the cover plate is removed from the interior.

Alternativ oder zusätzlich kann die Steuereinrichtung den Betriebsmodus eines Ventilators verändern, der im Innenraum des Geräts vorgesehen ist. Vorteilhafterweise ist ein solcher Ventilator derart angeordnet, dass eine Luftzirkulation in dem Spalt erfolgt, der zwischen der Gerätekorpusinnenwand und der vorgeblendeten Abdeckplatte vorgesehen ist. Beispielsweise kann der Ventilator im Bereich des oberen Endes der Abdeckplatte und/oder unter einer Decke des Innenraums angeordnet sein, so dass die von dem Ventilator bewirkte Luftzirkulation hinter und/oder vor der Abdeckplatte vorbei streicht.Alternatively or additionally, the control device can change the operating mode of a fan, which is provided in the interior of the device. Advantageously, such a fan is arranged such that an air circulation takes place in the gap, which is provided between the device body inner wall and the vorgeblendeten cover plate. For example, the fan can be arranged in the region of the upper end of the cover plate and / or under a ceiling of the inner space, so that the air circulation caused by the fan sweeps past behind and / or in front of the cover plate.

Die Steuereinrichtung kann dabei den Betriebsmodus des Ventilators je nach dessen Einbausituation unterschiedlich verändern. Ist der Ventilator fest im Innenraum montiert, können die Schaltzeiten bzw. Betriebsintervalle von der Steuereinrichtung verändert werden, je nachdem ob die Abdeckplatte eingesetzt ist oder entnommen ist.The control device can change the operating mode of the fan differently depending on its installation situation. If the fan is fixedly mounted in the interior, the switching times or operating intervals can be changed by the control device, depending on whether the cover plate is inserted or removed.

Alternativ kann der Ventilator auch an der Abdeckplatte selbst montiert sein, so dass er zusammen mit der Abdeckplatte entnehmbar ist. In diesem Fall kann die Steuereinrichtung einfach die Ventilator-Steuerroutine deaktivieren, wenn die Abdeckplatte entnommen ist.Alternatively, the fan may also be mounted on the cover plate itself, so that it can be removed together with the cover plate. In this case, the controller may simply deactivate the fan control routine when the cover plate is removed.

Die Anpassung des Gerätebetriebs je nachdem, ob die Abdeckplatte eingesetzt oder entnommen ist, erfolgt vorteilhafterweise automatisch. Hierzu kann eine Erfassungseinrichtung vorgesehen sein, die erfasst, ob die Abdeckplatte eingesetzt oder entnommen ist. Die Steuereinrichtung verändert dabei den genannten, zumindest einen Betriebsparameter zumindest einer kühltechnisch wirksamen Gerätekomponente in Abhängigkeit eines Signals der Erfassungseinrichtung.The adaptation of the device operation depending on whether the cover plate is inserted or removed, advantageously takes place automatically. For this purpose, a detection device be provided, which detects whether the cover plate is inserted or removed. In this case, the control device alters the mentioned, at least one operating parameter of at least one device component which is effective in cooling technology as a function of a signal of the detection device.

Insbesondere kann ein Reed-Schalter vorgesehen sein, der die Anwesenheit der Abdeckplatte im Innenraum erfasst.The detection device can basically be designed differently. According to an advantageous embodiment of the invention, the detection device operates without contact. In particular, a reed switch can be provided which detects the presence of the cover plate in the interior.

Die lösbaren Befestigungsmittel für die Abdeckplatte können grundsätzlich verschieden ausgebildet sein. Um bei Bedarf ein einfaches Herausnehmen der Abdeckplatte zu gewährleisten, sind die Befestigungsmittel vorteilhafterweise werkzeuglos nur von Hand lösbar bzw. umgekehrt schließ- bzw. befestigbar.The releasable fastening means for the cover plate can basically be designed differently. In order to ensure a simple removal of the cover plate when needed, the fastening means are advantageously without tools only by hand solvable or vice versa closing or fastened.

Insbesondere können die Befestigungsmittel die Abdeckplatte formschlüssig und/oder kraftschlüssig in dem Innenraum an der gewünschten Position vor der abzudeckenden Innenwand halten. Eine besonders einfach zu bedienende und dennoch stabile Befestigung wird durch Rastmittel vorgesehen, durch die die Abdeckplatte in dem Innenraum an der gewünschten Position verrastet werden kann.In particular, the fastening means can hold the cover plate positively and / or non-positively in the interior at the desired position in front of the inner wall to be covered. A particularly easy-to-use yet stable attachment is provided by latching means by which the cover plate can be locked in the interior at the desired position.
