Description

Haushaltkühlschrank Household refrigerator

Die Erfindung betrifft einen Haushaltkühlschrank mit einem durch eine Klappe verschließbaren Lagerfach für Nahrungsmittel, insbesondere Butterfach oder dgl.The invention relates to a household refrigerator with a through a Flap lockable storage compartment for food, especially butter compartment or like

Butter und ähnliche Speisefette sind bei der für die Lagerung günstigen Temperatur von + 2 bis 6°C relativ hart und daher nicht streichbar. Sie müssen entweder deshalb vor dem Gebrauch erwärmt, also beispielsweise längere Zeit vorher aus dem Kühlschrank genommen oder bei höherer Temperatur von etwa 12 bis 16 0C aufbewahrt werden. Aus der DU-PS 1 190 474 ist daher bereits ein Kühlschrank mit elektrisch beheizbarem Butterfach bekannt, das ständig auf eine für den Gebrauch der Butter optimale Temperatur eingeregelt werden kann. Da eine in solchen Fächern aufbewahrte Butter weniger lange haltbar ist, wurde der Heizeinrichtung ferner eine Schaltuhr zugeordnet, die vom Benutzer in wählbaren Zeiten eingeschaltet werden kann. Die Heizung und Regeleinrichtung bedingen einen großen Aufwand und zusätzlichen Energieverbrauch. Die elektrische Zuleitung zum dem in der gühlschranktür untergebrachten Butterfach verhindert einen Türanschlagwechsel.Butter and similar edible fats are cheap for storage Temperature of + 2 to 6 ° C relatively hard and therefore not paintable. You have to either therefore warmed up before use, for example out of the a long time beforehand Taken in the refrigerator or kept at a higher temperature of around 12 to 16 ° C will. From the DU-PS 1 190 474 is therefore already a refrigerator with electric heatable Butter compartment known that this is always at an optimal temperature for the use of the butter can be adjusted. Because butter stored in such compartments is shorter is durable, the heating device was also assigned a timer, which from User can be switched on at selectable times. The heating and control device require a lot of effort and additional energy consumption. The electric The supply line to the butter compartment housed in the refrigerator door prevents one Door hinge change.

Der Erfindung liegt die Aufgabe zugrunde, einen Haushaltkühlschrank der eingangs genannten Art so auszubilden, daß die Lagerfachtemperatur des Lagerfaches für Butter und ähnliche Nahrungsmittel mit einfachen Mitteln verstellt werden kann.The invention is based on the object of a household refrigerator of the type mentioned in such a way that the storage compartment temperature of the storage compartment for butter and similar foods can be adjusted with simple means.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Klappe eine Einrichtung zur Veränderung ihrer Wärmedurchgangszahl k aufweist. Aufgrund der Veränderung der Klappe kann die Lagerfachtemperatur in den Bereich der Eühlraumtemperatur abgesenkt (hoher k-Wert, verminderte Isolierung zwischen Kühlraum und Lagerfach) oder durch verstärkte Isolierung der Klappe (niedriger k-Wert) die Lagerfachtemperatur höher als die Kühlraumtemperatur gehalten werden.This object is achieved according to the invention in that the flap has a device for changing its heat transfer coefficient k. Because of The change in the flap can bring the storage compartment temperature into the range of the cooling room temperature lowered (high k-value, reduced insulation between cold room and storage compartment) or the storage compartment temperature by reinforced insulation of the flap (lower k-value) must be kept higher than the temperature in the refrigerator.

Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.Refinements of the invention are contained in the subclaims.

An Hand der Zeichnung wird die Erfindung näher erläutert.The invention is explained in more detail with reference to the drawing.

Es zeigt: Fig. 1 in perspektivischer Darstellung einen Abschnitt der Innenwand einer Kühlschranktür mit eingelassenem Butterfach und dazu getrennt eine mehrwandige Lagerfachklappe, wovon eine Wand durch einen Bedienungsknopf verschiebbar ist, Fig. 2 in einer Ansicht gemäß Fig. 1 eine Lagerfachklappe mit Wärmeisolierung, Kaltlufteinlaß- und Warmluftauslaßöffnungen.It shows: FIG. 1 a perspective illustration of a section of FIG Inner wall of a refrigerator door with an embedded butter compartment and a separate one multi-walled storage compartment flap, one wall of which can be moved by means of a control button FIG. 2 shows a storage compartment flap with thermal insulation in a view according to FIG. 1, Cold air inlet and hot air outlet openings.

Nach der gezeichneten Ausführungsmöglichkeit ist ein Lagerfach 1 für Nahrungsmittel, insbesondere ein Butterfach, in der Tür 2 eines Haushaltkühlschrankes vorgesehen. Die Tür besteht aus einer Außenwand 3, einer Innenhaube 4 und einer dazwischen befindlichen Isolierung 5. Mit 6 ist eine Abstellleiste über dem Lagerfach 1 bezeichnet.According to the embodiment shown, a storage compartment 1 is for Food, in particular a butter compartment, in the door 2 of a household refrigerator intended. The door consists of an outer wall 3, an inner hood 4 and one insulation in between 5. With 6 is a storage bar above the storage compartment 1 referred to.

Nach einer vorteilhaften Ausführung ist das Lagerfach 1 durch eine doppelwandige Klappe 7 verschließbar, die eine Einrichtung zur Veränderung der Wärmedurchgangszahl k zwischen dem Kühlraum des Kühlschrankes und dem Lagerfach 1 besitzt. Gemäß dem gezeichneten Ausführungsbeispiel weist die aus den Wänden 8, 9 bestehende Klappe 7 eine durch einen Betätigungsknopf 11 verschiebbare Isolierwand 10 auf. Zur Angleichung der Temperaturen des Lagerfaches 1 und des Kühlraumes des Kühlschrankes wird die Isolierwand 10 über die Wände 8, 9 geschoben, so daß im Bereich der vermindert isolierten Klappenwand 12 ein erhöhter Wärmeaustausch stattfinden kann.According to an advantageous embodiment, the storage compartment 1 is through a double-walled flap 7 closable, which is a device for changing the heat transfer coefficient k between the cold room of the refrigerator and the storage compartment 1 has. According to the The illustrated embodiment has the flap consisting of the walls 8, 9 7 an insulating wall 10 which can be displaced by means of an actuating button 11. For alignment the temperatures of the storage compartment 1 and the refrigerator compartment of the refrigerator is the Insulating wall 10 pushed over walls 8, 9, so that in the area the less insulated flap wall 12, an increased heat exchange take place can.

Desweiteren kann die Klappe 7 eine verschließbare Belüftungsöffnung aufweisen. Die Klappe 7 kann durch einen Handgriff 13 geöffnet werden. Wird die verschiebbare Wand 10 in die Endlage verschoben, in der die Klappe 7 auf der Gesamtfläche doppelwandig ist, so wird eine Lagerfachtemperatur erreicht, die über der des Kühlraumes liegt. Ist nur ein Teil der Gesamtfläche einwandig, so stellt sich eine relativ niedrige, im Bereich der Kühlraumtemperatur liegende Lagerfachtemperatur ein.Furthermore, the flap 7 can have a closable ventilation opening exhibit. The flap 7 can be opened by a handle 13. Will the displaceable wall 10 moved to the end position in which the flap 7 on the entire surface is double-walled, a storage compartment temperature is reached that is above that of the refrigerator lies. If only part of the total area is single-walled, then one is relative low storage compartment temperature in the range of the cold room temperature.
