Description
Kühlmöbel, insbesondere Haushaltkühlschrank Vom Standpunkt der Hausfrau aus gesehen, ist der heutige Haushaltkühlschrank keineswegs befriedigend.Refrigeration cabinets, especially household refrigerators From the point of view of the housewife From the point of view, today's household refrigerator is by no means satisfactory.
Die im Schrank eingeschlossene Luft überträgt Geruch und Geschmack von einer Speise auf die andere, wogegen man sich dadurch zu schützen sucht, daß jede Ware in geschlossenen Kasten bzw. Gemüsefächern aufbewahrt wird. Das wieder vertragen nicht alle Lebensmittel, wie z. B. Wurst- und Fleischwaren.The air trapped in the closet transmits smell and taste from one food to the other, against which one tries to protect oneself by each product is kept in closed boxes or vegetable compartments. That again do not tolerate all foods, such as B. Sausage and meat products.
Verschiedentlich wurden Luftreiniger, Ultraviolettlampen u. dgl. angeboten, durch deren Verwendung die erwähnten Nachteile vermieden werden sollten, die aber das Grundübel nicht beseitigen können.Air purifiers, ultraviolet lamps and the like were offered on various occasions, by using them, the disadvantages mentioned should be avoided, but the cannot eliminate the root cause.
Es ist bereits vorgeschlagen worden, Kühlräume mit zusätzlichen Zuluft- und Abluft-Öffnungen zu versehen, durch welche hindurch ein dauernder Luftdurchlaß durch den Kühlraum hindurch erfolgt. Es ist ferner vorgeschlagen worden, durch die Erwärmung der Abluft den Luftumlauf zu steuern. Demgegenüber besteht die Erfindung bei Kühlmöbeln mit je einer Zuluft- und Abluft-Öffnung darin, daß die Abluft-Öffnung, vorzugsweise über ein Rohrstück, im Saugbereich des Ventilators der Kühlmaschine so angeordnet ist, daß der Luftaustausch des Kühlraumes durch den Luftstrom des Ventilators bewirkt oder beeinflußt wird.It has already been proposed to provide cold rooms with additional supply air and to provide exhaust air openings through which there is a permanent passage of air takes place through the refrigerator. It has also been suggested by the Heating the exhaust air to control the air circulation. In contrast, there is the invention for refrigerated cabinets with one air inlet and one outlet air opening in that the outlet air opening, preferably via a piece of pipe, in the suction area of the fan of the cooling machine is arranged so that the air exchange of the refrigerator compartment by the air flow of the Fan caused or influenced.
Die zuströmende Luft kann in an sich bekannter Weise gefiltert, gereinigt, bestrahlt, getrocknet oder sonstwie behandelt werden, ebenso kann sie durch Abkühlung entfeuchtet werden.The incoming air can be filtered, cleaned, irradiated, dried or otherwise treated, it can also be cooled by cooling be dehumidified.
Zu diesem Zweck kann man im Kühlschrankgehäuse ein Rohr anbringen, in welches ein Staubfilter, eine Filterpatrone (z. B. mit Aktivkohle gefüllt), eine Trockenpatrone, eine Bestrahlungslampe eingesteckt ist, und welches in das Schrankinnere mündet.For this purpose, you can put a pipe in the refrigerator housing, in which a dust filter, a filter cartridge (e.g. filled with activated carbon), a Desiccant cartridge, a radiation lamp is plugged in, and which is in the cabinet interior flows out.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Abbildung dargestellt. Diese zeigt in schematischer Darstellung ein vorn geöffnetes Kühlschrankgehäuse unter Weglassung der Kühlschranktür und der Vorderwand.An embodiment of the subject invention is shown in the figure shown. This shows a schematic representation of a refrigerator housing open at the front omitting the refrigerator door and the front wall.
Im oberen Teil des Schrankes befindet sich der Nutzraum 1, innerhalb dessen ein an sich bekannter Kältemittelverdampfer 2 sowie Abstellroste 3 angeordnet sind.In the upper part of the cabinet is the utility space 1, inside one of which, known per se, refrigerant evaporator 2 and storage grids 3 are arranged are.
Unterhalb des Nutzraumes ist der Maschinenraum 4 angeordnet, in welchem Motorverdichter 5 und Kondensator 6 untergebracht sind. Motorverdichter 5 besitzt in an sich bekannter Weise einen Ventilator 7, um den Kondensator zur Wärmeabfuhr mit Raumluft anblasen zu können. Die Kältemaschine steht in der üblichen Weise mit dem Kondensator und dem Verdampfer über Leitungen (nicht dargestellt) in Verbindung.The machine room 4, in which Motor compressor 5 and condenser 6 are housed. Motor compressor 5 owns in a manner known per se a fan 7 to the condenser for heat dissipation to be able to blow room air. The chiller stands with in the usual way the condenser and the evaporator via lines (not shown) in connection.
In der Oberseite 8 des Kühlschrankgehäuses befindet sich ein Lufteinlaß 9, durch welchen Luft in den Nutzraum 1 eindringen kann; der Einlaß 9 befindet sich vorzugsweise so oberhalb des Verdampfers 2, daß die eindringende Luft von diesem herabgekühlt wird.In the top 8 of the refrigerator housing there is an air inlet 9 through which air can penetrate into the usable space 1; the inlet 9 is preferably located above the evaporator 2 in such a way that the penetrating air is cooled down by it.
In der Unterseite 10 des Gehäuses befindet sich ein Luftauslaß 11, und zwar vorzugsweise ein Rohr 12, welches hinter dem Ventilator 7 mündet derart, daß beim Laufen des Ventilators, also beim Betrieb der Kältemaschine, Luft aus dem Rohr 12 und damit aus dem Nutzraum 1 herausgesaugt wird, die sich über Einlaß 9 erneuert.In the bottom 10 of the housing there is an air outlet 11, and preferably a pipe 12 which opens behind the fan 7 in such a way that when the fan is running, i.e. when the refrigeration machine is running, air is removed from the Tube 12 and thus is sucked out of the usable space 1, which extends via inlet 9 renewed.
Während des Laufens der Kältemaschine findet also ein Luftdurchfluß durch den Nutzraum statt, dessen Stärke durch entsprechende Bemessung der Luftdurchlässe, Änderung der Saugwirkung des Ventilators od. dgl. beeinflußt werden kann.There is therefore a flow of air while the refrigeration machine is running through the usable space, whose strength is determined by the appropriate dimensioning of the air outlets, Change in the suction of the fan or the like. Can be influenced.
