Abstract

A domestic refrigerator ( 1 ) comprises a thermally insulated housing ( 2 ), a cold storage compartment ( 5 ) and a fresh food compartment ( 4 ) contained within the housing ( 2 ) and located on top of each other, a refrigerant circuit which comprises an evaporator ( 29 ) configured to directly cool the cold storage compartment ( 5 ), a first door leaf ( 18 ) for closing and opening the fresh food compartment ( 4 ), a second door leaf ( 19 ) for closing and opening the cold storage compartment ( 5 ), a divisional wall ( 17, 42 ) separating the cold storage compartment ( 5 ) from the fresh food compartment ( 5 ), and a air channel system ( 31, 32 ) which is configured to allow an air exchange between the cold storage compartment ( 5 ) and the fresh food compartment ( 4 ).

First claim

The invention claimed is:

1. A domestic refrigerator, the domestic refrigerator comprising:
a thermally insulated housing;
a cold storage compartment;
a fresh food compartment contained within the thermally insulated housing such that the fresh food compartment is located on top of the cold storage compartment;
a single refrigerant circuit which comprises a single evaporator configured to directly cool only the cold storage compartment;
a first door leaf configured to close and open the fresh food;
a second door leaf configured to close and open the cold storage compartment;
a divisional wall separately attachable to the housing and separating the cold storage compartment from the fresh food compartment; and
an air channel system configured to allow an air exchange between the cold storage compartment and the fresh food compartment,
wherein the domestic refrigerator further comprises a freezer compartment disposed below the cold storage compartment, wherein the freezer compartment comprises a second refrigerant circuit configured to cool the freezer compartment independently of the cold storage compartment and the fresh food compartment.

2. The domestic refrigerator of claim 1 , wherein at least one of the first door leaf and the second door leaf comprises a magnetic gasket attached on a surface facing towards the cold storage compartment or the fresh food compartment, respectively, and an edge of the divisional wall facing away from the cold storage compartment and the fresh food compartment comprises or is made at least partly from a metal.

3. The domestic refrigerator of claim 1 , wherein the first door leaf and the second door leaf are connected to the thermally insulated housing by hinges, at least one of the hinges being at least partly attached to an edge of the divisional wall facing away from the cold storage compartment and the fresh food compartment.

4. The domestic refrigerator of claim 1 , wherein the divisional wall or at least a main part of the divisional wall is inserted into and attached to the thermally insulated housing.

5. The domestic refrigerator of claim 4 , wherein the divisional wall or at least the main part of the divisional wall is attached to the thermally insulated housing by latching devices.

6. The domestic refrigerator of claim 4 , wherein the divisional wall or at least the main part of the divisional wall is configured to be detached from the thermally insulated housing only by a tool.

7. The domestic refrigerator of claim 4 , wherein the divisional wall or at least the main part of the divisional wall is configured to be detached from the thermally insulated housing without any tools.

8. The domestic refrigerator of claim 4 , wherein the divisional wall comprises the main part, which is inserted into and attached to the thermally insulated housing, and
wherein the divisional wall comprises a traverse which is rigidly fixed to and at a front side of the thermally insulated housing, and runs between side walls of the thermally insulated housing.

9. The domestic refrigerator of claim 8 , wherein at least one hinge is at least partly attached to an edge of the traverse facing away from the cold storage compartment and the fresh food compartment.

10. The domestic refrigerator of claim 1 , wherein the divisional wall or at least the main part of the divisional wall comprises at least one aperture or air channel which forms at least a part of the air channel system.

11. The domestic refrigerator of claim 10 , wherein the at least one aperture or the air channel is located near a front side of the domestic refrigerator, essentially extends about the entire width of the divisional wall, and/or runs parallel to a rear wall of the housing.

12. The domestic refrigerator of claim 1 , wherein the air channel system comprises an air channel, the air channel connecting the cold storage compartment with the fresh food compartment.

13. The domestic refrigerator of claim 12 , wherein the air channel is located inside a rear wall of the housing, is attached to a surface of the rear wall of the housing facing towards the cold storage compartment and the fresh food compartment, or is formed by a gap between the divisional wall and the surface of the rear wall of the thermally insulated housing facing towards the cold storage compartment and the fresh food compartment.

14. The domestic refrigerator of claim 13 , wherein the air channel extends to at least half of a height of the fresh food compartment.

15. The domestic refrigerator of claim 1 , wherein the divisional wall comprises at least one reinforcement component,
wherein the divisional wall comprises a thermally insulating part or is made from a thermally insulating material, and
wherein the divisional wall comprises a heating system and/or a heating tube connected to the single refrigerant circuit.

16. The domestic refrigerator of claim 1 , wherein the single evaporator is disposed within the cold storage compartment.

17. The domestic refrigerator of claim 1 , wherein at least a portion of the air channel system is disposed at least partially directly between a wall of the thermally insulated housing and the divisional wall.

18. The domestic refrigerator of claim 1 , wherein the fresh food compartment is only cooled by air from the cold storage compartment.
