Domestic refrigeration appliance with drawers that are displaceable relative to one another, wherein one drawer has at least three roller arrangements

Abstract

A domestic refrigeration appliance has an accommodating space for foodstuffs which is delimited by walls of an interior container. A drawer configuration is mounted within the accommodating space and contains a first drawer that is arranged on a door of the domestic refrigeration appliance that is configured to close the accommodating space and is displaceably coupled to the door, and a second drawer that is mounted so as to be displaceable relative to the first drawer. The second drawer has a first roller configuration by which the second drawer is displaceable on the first drawer. The second drawer has a second roller configuration by which the second drawer is guided on a guiding mechanism on a side wall of the interior container. The second drawer has a third roller configuration being staggered in relation to the first roller configuration viewed in the depth direction of the second drawer.
