Description

Die Erfindung betrifft einen Kühlschrank mit einem in dessen Innenraum oder in einer Wandung angeordneten Verdampfer und mit einer im Innenraum befindlichen Schale zum Auffangen des von dem Verdampfer oder der den Verdampfer abdeckenden Wandung abtropfen­den oder ablaufenden Kondensationswassers.The invention relates to a refrigerator with an evaporator arranged in its interior or in a wall and with a bowl located in the interior for collecting the condensation water dripping or draining from the evaporator or the wall covering the evaporator.

Die relative Luftfeuchtigkeit beträgt in statisch gekühlten Kühl­schränken üblicherweise etwa 40 - 45 %. Eine derart trockene Luft kann zu einer unerwünschten Austrocknung von Lebensmitteln führen. Beispielsweise läßt sich beobachten, daß ein in einen Kühlschrank eingestellter Salat innerhalb eines Tages welkt.The relative humidity in statically cooled refrigerators is usually around 40 - 45%. Such dry air can cause food to dry out undesirably. For example, it can be observed that a salad placed in a refrigerator wilts within a day.

Insbesondere ist die geringe relative Luftfeuchtigkeit in Wein­kühlschränken unerwünscht, da es bei den üblicherweise langen Lagerzeiten zu einem Verdunsten des Weines über den Korken kommen kann.In particular, the low relative air humidity in wine refrigerators is undesirable, since the wine can evaporate over the cork during the usually long storage times.

Aufgabe der Erfindung ist es daher, einen Kühlschrank der ein­gangs angegebenen Art zu schaffen, in dem auf einfache Weise eine höhere relative Luftfeuchtigkeit aufrechterhalten werden kann.The object of the invention is therefore to provide a refrigerator of the type specified in the introduction in which a higher relative air humidity can be maintained in a simple manner.

Erfindungsgemäß wird diese Aufgabe bei einem Kühlschrank der gattungsgemäßen Art dadurch gelöst, daß die Schale zumindest teilweise mit einem gut saugfähigen, porösen, sich gegenüber Wasser und den üblicheweise in den Kühlschrank eingelagerten Waren chemisch neutral verhaltenden Stoff gefüllt ist. Bei dem erfindungsgemäßen Kühlschrank wird also das von dem Verdampfer abtropfende Kondensationswasser zur Erhöhung der relativen Luft­feuchtigkeit in dem Kühlschrankinnenraum benutzt. Da allein in einer Schale stehendes Wasser zu keiner wesentlichen Erhöhung der Luftfeuchtigkeit führen würde, ist erfindungsgemäß ein in die Auffangschale eingelegter gut saugfähiger poröser Stoff vor­gesehen, der die zur Verdunstung zur Verfügung stehende Ober­fläche gegenüber der Querschnittsfläche der Schale um ein Viel­faches erhöht. Dieser Stoff saugt sich mit dem Kondensations­wasser voll und ruht in der Schale, in der entweder überhaupt kein freier Wasserspiegel oder aber ein Wasserspiegel vorhanden ist, aus dem der poröse Stoff herausragt.According to the invention, this object is achieved in a refrigerator of the generic type in that the shell is at least partially filled with a highly absorbent, porous substance which is chemically neutral in relation to water and the goods normally stored in the refrigerator. In the refrigerator according to the invention, the evaporator does this dripping condensation water used to increase the relative humidity in the refrigerator interior. Since water alone in a bowl would not lead to a significant increase in air humidity, according to the invention a well-absorbent porous substance is provided in the collecting bowl, which increases the surface area available for evaporation many times over the cross-sectional area of the bowl. This substance soaks up with the condensation water and rests in the bowl, in which there is either no free water level at all or a water level from which the porous material protrudes.

Ein besonders geeigneter Stoff ist Lavagestein, das bei großer Porosität eine ausreichende chemische Neutralität aufweist und billig ist. Das Lavagestein vergrößert somit die zur Verdunstung zur Verfügung stehende Oberfläche, ohne daß schädliche Neben­effekte aufgrund von Bakterienbefall oder Veralgungen oder uner­wünschten Reaktionen zu befürchten sind.A particularly suitable substance is lava rock, which has sufficient chemical neutrality and is cheap when porous. The lava stone thus increases the surface area available for evaporation without fear of harmful side effects due to bacterial attack or algae or undesirable reactions.

Die das poröse Material aufnehmende Schale kann aus einer einge­stellten Schale oder aber auch aus einer wannenförmigen Vertie­fung bestehen, die in einem waagerechten Teil der Innenwand des Kühlschrankgehäuses vorgesehen ist. Zweckmäßigerweise ist die Vertiefung in einem stufenartigen Absatz angeordnet, der durch die den Kompressor aufnehmende Nische gebildet ist.The bowl receiving the porous material can consist of an adjusted bowl or else of a trough-shaped depression which is provided in a horizontal part of the inner wall of the refrigerator housing. The depression is expediently arranged in a step-like shoulder, which is formed by the niche receiving the compressor.

Üblicherweise läuft das von dem Verdampfer abtropfende Konden­sationswasser durch eine trichterförmige Ablaufrinne in eine Verdunstungsschale, die außerhalb des Kühlraums auf dem Kom­pressor befestigt ist, wobei die Kompressorwärme zu einer schnellen Verdunstung genutzt wird. Die eingesetzte Schale oder wannenförmige Vertiefung kann ebenfalls mit einer zu einer außerhalb des Innenraumes auf den Kompressor angeordneten Verdunstungsschale führenden Leitung versehen sein. Durch diese Leitung wird überschüssiges Kondensationswasser abgeführt, das von dem porösen Stoff nicht aufgesaugt wird.Usually, the condensation water dripping from the evaporator runs through a funnel-shaped drainage channel into an evaporation tray, which is attached to the compressor outside the cooling chamber, the compressor heat being used for rapid evaporation. The shell or trough-shaped depression used can likewise be provided with a line leading to an evaporation shell arranged outside of the interior on the compressor. Through this Excess condensation water is drained off, which is not absorbed by the porous substance.

Zweckmäßigerweise ist die Leitung syphonartig mit einem Rohr­stück versehen, das ausgehend von dem Boden der Schale oder Wandung nach oben ragt. Dieser syphonartige Überlauf leitet dann überschüssiges Kondensationswasser in die auf dem Kompressor an­geordnete Verdunstungsschale.The line is expediently provided with a piece of pipe that extends upwards from the bottom of the shell or wall. This siphon-like overflow then guides excess condensation water into the evaporation tray arranged on the compressor.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur ein Vertikalschnitt durch das Kühlschrankgehäuse im Bereich der Kompressornische darge­stellt ist, näher erläutert.An embodiment of the invention is explained in more detail below with reference to the drawing, in the single figure of which a vertical section through the refrigerator housing is shown in the area of the compressor niche.

Die Rückwand 1 des Kühlschrankgehäuses ist mit einem stufen­artigen Absatz 7 versehen, der durch die nach außen hin offene Nische 8 gebildet ist, in der der Kompressor 2 untergebracht ist. Auf dem Kompressor 2 ist eine nach oben hin offene Ver­dunstungsschale 3 befestigt. Parallel zu der Rückwand 1 ist der Verdampfer 4 angeordnet. Soweit ist der Kühlschrank bekannter Bauart.The rear wall 1 of the refrigerator housing is provided with a step-like shoulder 7, which is formed by the recess 8 which is open to the outside and in which the compressor 2 is accommodated. On top of the compressor 2, an evaporation shell 3 open at the top is attached. The evaporator 4 is arranged parallel to the rear wall 1. So far the refrigerator is of a known design.

In der Oberseite des sockelartigen Absatzes 7 ist eine wannen­förmige Vertiefung 8 vorgesehen. In dem Boden 9 dieser wannen­förmigen Vertiefung ist ein Rohr 5 angeordnet, das über den Boden der wannenförmigen Vertiefung nach oben ragt. Ober dieses syphonartige Rohr 5 kann überschüssiges Kondensationswasser in die Verdunstungsschale 3 laufen.A trough-shaped depression 8 is provided in the top of the base-like shoulder 7. In the bottom 9 of this trough-shaped depression, a tube 5 is arranged, which projects upwards over the bottom of the trough-shaped depression. Excess condensation water can run into the evaporation tray 3 via this siphon-like tube 5.

Die wannenförmige Vertiefung 8 ist mit Lavagestein 6 gefüllt.The trough-shaped depression 8 is filled with lava stone 6.
