Domestic refrigerator and method for ventilating a refrigerator compartment container

Abstract

A domestic refrigerator has a refrigeration compartment and a container which can be accommodated in the refrigeration compartment and has a lower part for receiving products to be refrigerated and a cover that can cover the lower part. The container has an air inlet opening and an air outlet opening that is at a distance from the air inlet opening. The domestic refrigerator also has a controllable air flow adjustment device and is configured to vary a volume flow rate of an air flow, which enters the container from the refrigeration compartment through the air inlet opening, between at least two values by adjusting an adjustment parameter of the air flow adjustment device. Furthermore, a method ventilates the container which is accommodated in the refrigeration compartment and has the air inlet opening and the air outlet opening.
