Kühlgerätcooling unit
Die Erfindung betrifft ein Kühlgerät mit einem Innenbehälter, in dem ein Verdampfer und ein Kompressor angeordnet sind.The invention relates to a cooling device with an inner container, in which an evaporator and a compressor are arranged.
Üblicherweise treten in den Kühlgeräten bedingt durch die diskontinuierliche Arbeitsweise des Verdichters hohe Schwankungen der Luftfeuchte auf. Dies ist insbesondere dann von Nachteil, wenn im Kühlgerät Lagergut aufbewahrt werden soll, das empfindlich gegenüber Feuchteveränderungen in der Umgebungsluft ist. Ein derart empfindliches Lagergut sind beispielsweise Zigarren oder auch Pharmapro- dukte. Für Zigarren ist als optimale Lagertemperatur eine Temperatur von +18CC bei einer Luftfeuchte von 75% einzustellen. Bislang existiert noch kein Kühlgerät, das eine geringe Hysterese der Luftfeuchtigkeit im Gerät aufweist.Usually occur in the refrigerators due to the discontinuous operation of the compressor high fluctuations in air humidity. This is particularly disadvantageous when storage goods are to be stored in the refrigerator, which is sensitive to moisture changes in the ambient air. Such sensitive storage goods are, for example, cigars or even pharmaceutical products. For cigars a temperature of +18 C C at a humidity of 75% is to be set as optimum storage temperature. So far, there is no cooling device that has a low hysteresis of humidity in the device.
Aufgabe der vorliegenden Erfindung ist es daher, ein Kühlgerät zu schaffen, das die Lagerung von einem Lagergut ermöglicht, das empfindlich gegenüber Veränderungen der Luftfeuchtigkeit ist. Es soll - mit anderen Worten - ein Kühlgerät geschaffen werden, das zur Lagerung von Zigarren, Pharmaprodukten oder einem anderen gegenüber Klimaschwankungen empfindlichen Lagergut geeignet ist. Erfindungsgemäß wird diese Aufgabe ausgehend von einem Kühlgerät gemäß dem Oberbegriff des Anspruchs 1 durch die Kombination mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst. Demnach wird an einem Kühlgerät mit einem ersten Innenbehälter, in dem ein Verdampfer angeordnet ist, ein zweiter Innenbehälter vorgesehen. Dabei umgibt der erste Innenbehälter den zweiten Innenbehälter derart, daß ein Zwischenraum zwischen dem ersten und dem zweiten Innenbehälter gebildet ist. Innerhalb des zweiten Innenbehälters ist das Lagergut aufbewahrt.Object of the present invention is therefore to provide a cooling device that allows the storage of a stored goods that is sensitive to changes in humidity. It is to be created - in other words - a refrigerator that is suitable for storage of cigars, pharmaceuticals or other sensitive to climatic fluctuations stored goods. This object is achieved on the basis of a cooling device according to the preamble of claim 1 by the combination with the features of the characterizing part of claim 1. Accordingly, a second inner container is provided on a cooling device with a first inner container, in which an evaporator is arranged. In this case, the first inner container surrounds the second inner container such that a gap between the first and the second inner container is formed. The stored goods are stored inside the second inner container.
Aufgrund des Vorsehens des zweiten Innenbehälters wird eine luftdichte Trennung zwischen Kühlsystem und Lagerraum geschaffen. Somit kann sich die Luftfeuchtigkeit innerhalb des zweiten Innenraums während der Verdichterlaufzeit nicht mehr am Verdampfer niederschlagen, was bei den konventionellen Kühlgeräten zum plötzlichen Rückgang der Luftfeuchte führt. Aufgrund des Vorsehens des zweiten Innenbehälters und des Zwischenraums zwischen ersten und zweiten Innenbehälter wird eine gleichmäßige Kühlung des Innenraums innerhalb des zweiten Innenbehälters gewährleistet. Eine Tropfenbildung von sich niederschlagender Feuchtigkeit an der Rückwand des zweiten Innenbehälters erfolgt durch die dynamische Belüftung nicht.Due to the provision of the second inner container, an air-tight separation between the cooling system and storage space is created. Thus, the humidity within the second interior during the compressor run time can no longer be reflected on the evaporator, which leads to the sudden cooling of the humidity in conventional refrigerators. Due to the provision of the second inner container and the space between the first and second inner container uniform cooling of the interior is ensured within the second inner container. Drop formation of precipitating moisture on the rear wall of the second inner container does not occur due to the dynamic aeration.
Bevorzugte Ausgestaltungen 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.
Demnach kann innerhalb des zweiten Innenbehälters eine Befeuchtungseinheit angeordnet sein. Aufgrund des Vorsehens dieser an sich im Aufbau bekannten Befeuchtungseinheit kann im Innenraum des Kühlgeräts, der vom zweiten Innenbehälter umschlossen wird, eine gewünschte Luftfeuchtigkeit eingestellt werden.Accordingly, a moistening unit can be arranged within the second inner container. Due to the provision of this humidification unit, which is known per se in structure, a desired air humidity can be set in the interior of the refrigerator, which is enclosed by the second inner container.
Vorteilhaft wird die Befeuchtungseinheit durch einen elektromechanischen oder elektronischen Hygrostat mit verstellbarer Hysterese angesteuert. Dies bedeutet, daß die maximal zugelassene Schwankung der Luftfeuchtigkeit entsprechend dem zu lagernden Lagergut eingestellt werden kann.Advantageously, the humidification unit is controlled by an electromechanical or electronic humidistat with adjustable hysteresis. This means, that the maximum permitted fluctuation of the humidity can be adjusted according to the stored goods to be stored.
Besonders vorteilhaft ist in der Wandung des zweiten Innenbehälters eine Entfeuchtungsklappe angeordnet, die eine Verbindung zum Zwischenraum zwischen dem ersten und dem zweiten Innenbehälter ermöglicht. Durch entsprechendes Öffnen der Klappe kann feuchtebeladene Luft in den Zwischenraum zwischen dem ersten Innenbehälter und dem zweiten Innenbehälter abfließen, so daß der Feuchtegehalt im Innenraum des zweiten Innenbehälters reduziert werden kann. Auch die Entfeuchtungsklappe kann durch den Hygrostat angesteuert werden.Particularly advantageously, a dehumidification flap is arranged in the wall of the second inner container, which allows a connection to the intermediate space between the first and the second inner container. By appropriately opening the flap, moisture-laden air can flow into the intermediate space between the first inner container and the second inner container, so that the moisture content in the interior of the second inner container can be reduced. The dehumidification flap can also be controlled by the hygrostat.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung kann im Zwischenraum zwischen dem ersten und dem zweiten Innenbehälter eine Belüftungseinrichtung vorgesehen sein, um die Luft im Zwischenraum umzuwälzen. Hierdurch wird ein gleichmäßiges Überströmen der Zwischenwand zwischen dem Zwischenbehälter und dem zweiten Innenbehälter sichergestellt, so daß die Temperatur im zweiten Innenbehälter aufgrund der gleichmäßigen Temperatur der Zwischenwand recht schnell auf den gewünschten Wert eingestellt werden kann.According to a further advantageous embodiment of the invention, a ventilation device may be provided in the intermediate space between the first and the second inner container in order to circulate the air in the intermediate space. As a result, a uniform overflow of the intermediate wall between the intermediate container and the second inner container is ensured, so that the temperature in the second inner container due to the uniform temperature of the intermediate wall can be adjusted quite quickly to the desired value.
Der im ersten Innenbehälter angeordnete Verdampfer ist vorteilhaft eingeschäumt.The arranged in the first inner container evaporator is advantageously foamed.
Unterhalb des Verdampfers kann eine Verdunstungsschale derart angeordnet sein, daß sich im Bereich des Verdampfers bildendes Wasser in die Verdunstungsschale ablaufen kann. Dabei kann die Verdunstungsschale vorteilhaft zusammen mit dem Kompressor in einem im unteren Bereich des ersten Innenbehälters ausgenommenen Aufnahmebereich angeordnet sein. In der Wandung zwischen dem Zwischenraum und dem Aufnahmeraum kann ein Verbindungskanal zur Ableitung des sich in einer trichterartigen Erweiterung des Verbindungskanals sammelnden Wassers vorgesehen sein.Below the evaporator, an evaporation tray can be arranged such that in the region of the evaporator forming water can drain into the evaporation tray. In this case, the evaporation tray may advantageously be arranged together with the compressor in a receiving area which is recessed in the lower area of the first inner container. In the wall between the intermediate space and the receiving space, a connecting channel for discharging the collecting in a funnel-like extension of the connecting channel water can be provided.

In der Figur 1 und 2 ist ein Kühlgerät 10 dargestellt, das einen ersten Innenbehälter 12 aufweist. Mit dem Innenbehälter ist in üblicher Weise über Scharniere eine Kühlgerätetür 14 verbunden. An der Rückwand des Innenbehälters 12 ist ebenfalls in bekannter Art und Weise ein großflächiger Verdampfer 16 eingeschäumt. Im unteren hinteren Bereich umschließt das geschäumte Gehäuse 13 einen Aufnahmeraum 18, in dem ein Kompressor 20 und eine Verdunstungsschale 22 angeordnet sind. Soweit entspricht der Aufbau des Kühlgeräts gemäß der Figuren 1 und 2 dem Aufbau von bereits bekannten Kühlgeräten.In the figure 1 and 2, a cooling device 10 is shown, which has a first inner container 12. With the inner container a refrigerator door 14 is connected in the usual way via hinges. On the rear wall of the inner container 12, a large-scale evaporator 16 is also foamed in a known manner. In the lower rear area encloses the foamed housing 13 a receiving space 18 in which a compressor 20 and an evaporation tray 22 are arranged. As far as corresponds to the structure of the refrigerator according to Figures 1 and 2, the structure of already known refrigerators.
Der Innenbehälter 12 umgibt einen zweiten Innenbehälter 24 derart, daß ein Zwischenraum 26 zwischen dem ersten Innenbehälter 12 und dem zweiten Innenbehälter 24 gebildet ist. In der Ausführungsform gemäß der Figuren 1 und 2 wird deutlich, daß der Zwischenraum 26 vollflächig zwischen dem ersten Innenbehälter und dem zweiten Innenbehälter ausgebildet ist. Die einzige Ausnahme bildet die Vorderseite, die durch die Tür 14 verschlossen ist. Innerhalb des Zwischenraums ist eine Belüftungseinrichtung 28 vorgesehen, mit der die sich im Zwischenraum befindliche Luft in Richtung der in den Figuren 1 und 2 dargestellten Pfeile in Bewegung versetzt wird. Damit überstreicht die Luft im Zwischenraum die Zwischenwandung 30 zwischen dem Zwischenraum 26 und dem vom zweiten Innenbehälter 24 umschlossenen Innenraum 32.The inner container 12 surrounds a second inner container 24 such that a gap 26 between the first inner container 12 and the second inner container 24 is formed. In the embodiment according to Figures 1 and 2 it is clear that the gap 26 over the entire surface between the first inner container and is formed the second inner container. The only exception is the front, which is closed by the door 14. Within the interspace, a ventilation device 28 is provided, with which the air located in the intermediate space is set in motion in the direction of the arrows shown in FIGS. 1 and 2. Thus, the air in the intermediate space sweeps over the intermediate wall 30 between the intermediate space 26 and the inner space 32 enclosed by the second inner container 24.
Im Innenraum 32 ist ein in ihrem Aufbau bereits bekannte Befeuchtungseinheit 34 im Bodenbereich angeordnet. Über die Befeuchtungseinheit 34, die durch einen hier nicht mehr dargestellten Hygrostat ansteuerbar ist, kann eine gewünschte Luft- feuchte im Innenraum 32 des Kühlgeräts 10 eingestellt werden. Um bei Bedarf eine schnelle Entfeuchtung im Innenraum 32 zu ermöglichen, ist eine vorteilhaft über dem Hygrostat ansteuerbare Entfeuchtungsklappe 36 in der Zwischenwand 30 vorgesehen. Diese ermöglicht es nach ihrem Öffnen, feuchtebeladene Luft aus dem Innenraum 32 in den Zwischenraum 26 einströmen zu lassen.In the interior 32, a humidification unit 34, which is already known in its construction, is arranged in the floor area. A desired air humidity in the interior 32 of the cooling device 10 can be adjusted via the humidification unit 34, which can be controlled by a hygrostat, which is no longer shown here. In order to enable rapid dehumidification in the interior space 32 if necessary, a dehumidification flap 36, which can advantageously be activated via the hygrostat, is provided in the intermediate wall 30. This makes it possible after their opening, humid air from the interior 32 to flow into the gap 26.
Wie insbesondere aus der Figur 1 ersichtlich bildet der erste Innenbehälter 12 im unteren und hinteren Bereich des Kühlgeräts 10 einen den Aufnahmeraum 18 umschließenden Absatz 38. In diesem Absatz 38 ist ein Verbindungskanal 40 ausgebildet, der den Zwischenraum 26 und den Aufnahmeraum 18 miteinander verbindet. Unterhalb des Verbindungskanals 40 ist die Verdunstungsschale 22, die im hier dargestellten Ausführungsbeispiel auf dem Kompressorgehäuse aufsitzt, angeordnet. An seinem zum Zwischenraum 26 zugewandten Ende erweitert sich der Verbindungskanal 40 unter Bildung einer trichterförmigen Aufnahme 42. In diese trichterförmige Aufnahme 42 kann sich im Bereich des vorteilhaft eingeschäumten Verdampfers 16 bildendes Kondenswasser sammeln. Dieses Kondenswasser fließt aufgrund der Schwerkraft durch den Verbindungskanal 40 und tropft in die Verdunstungsschale 22.As can be seen in particular from FIG. 1, the first inner container 12 in the lower and rear region of the cooling device 10 forms a shoulder 38 surrounding the receiving space 18. In this shoulder 38, a connecting channel 40 is formed which connects the intermediate space 26 and the receiving space 18. Below the connecting channel 40, the evaporation tray 22, which is seated on the compressor housing in the embodiment shown here, arranged. At its end facing the intermediate space 26, the connecting channel 40 expands to form a funnel-shaped receptacle 42. In this funnel-shaped receptacle 42, condensation water forming in the region of the advantageously foamed-in evaporator 16 can collect. This condensate flows by gravity through the connecting channel 40 and drips into the evaporation tray 22nd
Die Ausführungsform gemäß der Figuren 3 und 4 entspricht im wesentlichen derjenigen gemäß der Figuren 1 und 2. Der wesentliche Unterschied besteht hier darin, daß der Zwischenraum 26 zwischen dem ersten und dem zweiten Innenbehälter nicht den gesamten Innenbehälter (bis auf den Bereich der Tür) umschließt. Vielmehr ist der Zwischenraum 26 in dieser Ausführungsform nur im Seitenbereich angeordnet. Weiterhin ist die Belüftungseinrichtung 28 im unteren Bereich des Kühlgeräts 10 angeordnet. Schließlich ist hier anders als in der Ausführung gemäß der Figuren 1 und 2 keine Verdampferplatte im Rückwandbereich des Innenbehälters angeordnet. Vielmehr sind hier die Verdampfer 16 jeweils seitlich im Bereich des Innenbehälters 12 eingeschäumt. Aufgrund der Anordnung des Zwischenraums 26 wird sichergestellt, daß der durch die Belüftungseinrichtung 28 in Umlauf gebrachte Luftstrom über die gekühlte Fläche an der Seitenwand strömt, um hier einen möglichst guten Wärmeübergang zu ermöglichen. In der Ausführungsform gemäß der Figuren 3 und 4 ist die Entfeuchtungsklappe 36 in der Zwischenwand im Bereich der Seitenwandung des Innenbehälters 12 angeordnet.The embodiment according to FIGS. 3 and 4 substantially corresponds to that according to FIGS. 1 and 2. The essential difference here is that that the intermediate space 26 between the first and the second inner container does not surround the entire inner container (except for the area of the door). Rather, the gap 26 is arranged in this embodiment only in the side area. Furthermore, the ventilation device 28 is arranged in the lower region of the cooling device 10. Finally, unlike in the embodiment according to FIGS. 1 and 2, no evaporator plate is arranged in the rear wall region of the inner container. Rather, here the evaporator 16 are each foamed laterally in the region of the inner container 12. Due to the arrangement of the gap 26 ensures that the air flow circulated through the ventilation device 28 flows over the cooled surface on the side wall to allow the best possible heat transfer. In the embodiment according to FIGS. 3 and 4, the dehumidifying flap 36 is arranged in the intermediate wall in the region of the side wall of the inner container 12.
Das Kühlgerät gemäß der Figuren 5 und 6 entspricht im wesentlichen demjenigen gemäß Figur 3. Wie anhand der Darstellung der Figuren 5 und 6 zu ersehen, ist allerdings der Zwischenraum 26 zwischen Innenbehälter 12 und zweitem Innenbehälter 24, durch den die Luft entsprechend der Pfeile in Figur 5 bzw. 6 strömt, nicht in den unteren Bereich des Kühlgeräts 10 gezogen, also in den Bereich, in welchem sich die Befeuchtung befindet. Vielmehr erstreckt der Zwischenraum 26 hier nur, wie durch die Pfeile dargestellt, oberhalb des unteren Bereichs, in welchem die Befeuchtung erfolgt. Die Belüftungseinrichtung 28 ist daher auch im oberen Bereich des Kühlgeräts angeordnet, wie sich aus den Figuren 5 und 6 ergibt. The cooling device according to FIGS. 5 and 6 essentially corresponds to that according to FIG. 3. As can be seen from the illustration of FIGS. 5 and 6, however, the intermediate space 26 between the inner container 12 and the second inner container 24 through which the air corresponds to the arrows in FIG 5 or 6 flows, not drawn into the lower portion of the refrigerator 10, ie in the area in which the humidification is located. Rather, the gap 26 extends here only, as shown by the arrows, above the lower region in which the moistening takes place. The ventilation device 28 is therefore also located in the upper region of the refrigerator, as is apparent from Figures 5 and 6.
