Abstract

A cabinet (1) with a refrigeration unit (7) is designed to be kept outdoors. It has electric heaters (4), or circulation channels for warm fluids, which are activated at low ambient temperatures which may otherwise cause the contents to freeze.

Description

Die Erfindung bezieht sich auf ein Kühlmöbel beliebiger Bauart, das mit einem üblichen Kühlaggregat und einer Steuerung ausgestattet ist, welche die Temperatur im Warenraum im eingestellten Bereich konstant hält.The invention relates to any refrigeration cabinet Design that with a usual cooling unit and a Control is equipped which controls the temperature in the goods room keeps constant in the set range.

Bei solchen Kühlmöbeln ist es üblich, daß Sensoren die Temperatur im Warenraum dahingehend überwachen, daß sie nicht über ein eingestelltes Maß hinaus ansteigen. In Abhängigkeit von der Reaktion der Sensoren wird dann das Kühlaggregat ein- bzw. abgestellt.In such refrigerators, it is common for sensors to be the Monitor the temperature in the goods room so that it do not rise above a set level. Dependent on the reaction of the sensors then becomes that Cooling unit switched on or off.

Die Erfindung befaßt sich mit dem Problem, im Frostbereich liegende Außentemperaturen nicht auf die Temperatur im Warenraum einwirken zu lassen. Dieses Problem entsteht beispielsweise dann, wenn das Kühlmöbel nicht im Innenraum eines Hauses, sondern aus Platzgründen im Freien, beispielsweise auf einem Balkon, aufgestellt wird. Hier entsteht die Gefahr, daß stark sinkende und im Frostbereich befindliche Außentemperaturen zum Einfrieren der Waren im Kühlfach führen können.The invention addresses the problem in the frost area outside temperatures do not depend on the temperature in the goods room to take effect. This problem arises, for example then when the refrigerator is not in the interior of a house, but for reasons of space outdoors, for example on a balcony. Here arises the risk of falling and in the frost area external temperatures for freezing the goods in the Can lead refrigerator compartment.

Um diesen Nachteil zu vermeiden, sieht die Erfindung vor, daß eine auf den Warenraum einwirkende, von der Außentemperatur abhängig gesteuerte Heizung zur Vermeidung eines Temperaturabfalles unter den gewünschten Kühlbereich vorgesehen ist.In order to avoid this disadvantage, the invention provides that one acting on the goods room, from the outside temperature dependent controlled heating to avoid a Temperature drop below the desired cooling range provided is.

Dadurch wird die Möglichkeit geschaffen, die im Warenraum befindliche Ware gegen Frosteinwirkung zu schützen, was besonders beim Kühlen von Lebensmitteln und Getränken erwünscht ist. This creates the possibility that in the goods room to protect goods against frost, what especially desirable when cooling food and beverages is.

Die erfindungsgemäße Heizung kann auf verschiedene Weise gestaltet sein. So ist es beispielsweise möglich, im Warenraum mindestens einen vornehmlich elektrisch wirkenden Heizkörper anzuordnen, der als Wärmetauscher wirkt. Wenn im Warenraum die Kühltemperatur unter den eingestellten Bereich abfällt, spricht ein Sensor an, der vorübergehend den Heizkörper einschaltet, bis die Kühl-Raumtemperatur wieder im eingestellten Bereich zu liegen kommt.The heating according to the invention can be done in different ways be designed. For example, it is possible in the warehouse at least one primarily electrically acting Arrange radiator that acts as a heat exchanger. If in the goods room the cooling temperature below the set Area falls, a sensor responds temporarily the radiator turns on until the cooling room temperature comes back to the set area.

Es ist andererseits möglich, Wandbereiche im Kühlraum mit Kanälen zum Durchströmen eines Heizmediums zu versehen. Dieses Heizmedium kann auch von außen her in die Wandung des Kühlmöbels eingeführt werden. Hierzu empfiehlt sich beispielsweise der Anschluß an eine Brauchwasserleitung oder an eine sonstige externe Wärmequelle. On the other hand, it is possible to have wall areas in the cold room Provide channels for the flow of a heating medium. This heating medium can also enter the wall from the outside of the refrigerator are introduced. We recommend doing this for example the connection to a hot water pipe or to another external heat source.

In der Zeichnung ist die Erfindung schematisch und beispielsweise dargestellt. Es zeigen:

Figur 1:
einen Vertikalschnitt durch ein Kühlmöbel mit einem im Warenraum angeordneten Heizkörper und
Figur 2:
einen Vertikalschnitt durch ein anderes Kühlmöbel mit in der Wandung des Warenraumes befindlichen Heizkanälen.
In the drawing the invention is shown schematically and for example. Show it:
Figure 1:
a vertical section through a refrigerator with a radiator arranged in the store and
Figure 2:
a vertical section through another refrigerator with heating channels located in the wall of the goods room.

Figur 1 zeigt als Beispiel ein Kühlmöbel (1) aufrechter Bauart, beispielsweise einen Kühlschrank. Der Warenraum (2) wird von einem Kühlaggregat (7) bekannter Bauart gekühlt.Figure 1 shows an example of a refrigerator (1) upright Type, for example a refrigerator. The goods room (2) is cooled by a cooling unit (7) of a known type.

Innerhalb des Warenraumes (2) befindet sich eine Heizung (3) in Form eines Heizkörpers (4), der beispielsweise als Elektroheizkörper ausgebildet sein kann.There is a heater inside the goods area (2) (3) in the form of a radiator (4), for example as Electric radiator can be formed.

Mit dem Kühlaggregat (7) wird eine Kühltemperatur in einem vorgegebenen Bereich, beispielsweise von 0° C bis 10° C erzeugt. Wenn diese Kühltemperatur durch äußere Einflüsse, beispielsweise durch starken Frost, unterschritten wird, besteht die Gefahr, daß die im Warenraum (2) befindlichen Waren, insbesondere Lebensmittel, Getränke oder dergleichen, einfrieren können.With the cooling unit (7) a cooling temperature in one predetermined range, for example from 0 ° C to 10 ° C generated. If this cooling temperature due to external influences, for example due to severe frost, there is a risk that those in the goods room (2) Goods, in particular food, beverages or the like, can freeze.

Die Heizung (3) bzw. der Heizkörper (4) werden in diesem Fall temperaturabhängig vorübergehend eingeschaltet, um die Kühltemperatur im Warenraum im eingestellten Bereich konstant zu halten. The heater (3) or the radiator (4) are in this Case turned on temporarily depending on temperature the cooling temperature in the goods area in the set range to keep constant.

Hierzu empfiehlt es sich, außerhalb des Kühlmöbels Sensoren zur Messung der Außentemperatur anzuordnen und im Warenraum (2) weitere Sensoren vorzusehen, die gemeinsam oder für sich einzeln die Steuerung der Energiezufuhr veranlassen.It is recommended to use sensors outside the refrigerator to arrange for measuring the outside temperature and in the goods room (2) provide additional sensors that are common or individually control the energy supply.

Im Beispiel der Figur 2 ist eine andere Variante dargestellt, wonach in Wandbereichen (6) des Kühlmöbels (1) Heizkanäle (5) integriert sind, durch die bei Bedarf ein Heizmedium fließen kann. Die Quelle für das Heizmedium kann durchaus extern angeordnet sein, beispielsweise dergestalt, daß die Kanäle (5) an die Brauchwasserleitung des Gebäudes angeschlossen und der Durchfluß durch Ventile gesteuert wird, die wiederum von Sensoren abhängig wirken.Another variant is shown in the example in FIG. 2, after which in wall areas (6) of the refrigerator (1) Heating channels (5) are integrated, through which if necessary Heating medium can flow. The source of the heating medium can be arranged externally, for example, that the channels (5) to the hot water pipe of the Building connected and the flow controlled by valves which, in turn, depend on sensors.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, sondern umfaßt alle Varianten, die sich in Kenntnis der erfindungsgemäßen Offenbarung für den Fachmann ergeben. The invention is not based on the embodiment shown limited, but encompasses all variants that are with knowledge of the disclosure according to the invention for the Specialist result.
