Abstract

Die Erfindung betrifft einen Kühlschrank mit einem oberen Kühlfach (6) und einem unteren Kaltlagerfach (7), die durch eine horizontale Zwischenwand (4) voneinander getrennt sind, und mit mindestens einer diese verschließenden Tür (8) oder Klappe, bei dem im oberen Bereich des Kühlfachs (6) ein Kühlgebläse (11) angeordnet und durch eine zu der Rückwand (2) des Kühlfachs (6) in etwa parallele Zwischenwand (9) ein Kühlluftkanal (10) abgeteilt ist, in dem sich ein Verdampfer (13) befindet und der durch Durchbrüche (15) im hinteren Bereich der Zwischenwand (4) in das Kaltlagerfach (7) mündet, bei dem im vorderen Bereich der Zwischenwand (4) Durchbrüche (19) und/oder ein Spalt zwischen der Zwischenwand und der Tür vorgesehen sind, durch die die Kühlluft in das Kühlfach (6) eintritt, und bei dem die Kälteverteilung durch die Laufzeit des Kompressors und/oder die Einschaltdauer und/oder die Drehzahl des Kühlgebläses (11) gesteuert wird.

Figure 00000001
The invention relates to a refrigerator with an upper cooling compartment (6) and a lower cold storage compartment (7), which are separated from one another by a horizontal intermediate wall (4), and with at least one door (8) or flap closing this, in the upper area a cooling fan (11) is arranged in the cooling compartment (6) and a cooling air duct (10) in which an evaporator (13) is located is separated by an intermediate wall (9) which is approximately parallel to the rear wall (2) of the cooling compartment (6) which opens through openings (15) in the rear area of the intermediate wall (4) into the cold storage compartment (7), in which openings (19) and / or a gap between the intermediate wall and the door are provided in the front area of the intermediate wall (4), through which the cooling air enters the cooling compartment (6), and in which the cold distribution is controlled by the running time of the compressor and / or the duty cycle and / or the speed of the cooling fan (11).
