Abstract

The present invention pertains to a fan assembly for a refrigerator. Said assembly comprises a fan with a first and a second outer wall at two ends along axial direction of said fan. Said outer walls extend perpendicular to said axial direction of said fan. Said fan assembly comprises a wall element which delimits an evaporator within said refrigerator. Said wall element has a fan mounting opening with projecting edges in the direction of said fan, said fan assembly further comprising an isolator and a locking element.

First claim

The invention claimed is:

1. A fan assembly for a refrigerator, said assembly comprising a fan case with a first and a second outer wall at two ends along axial direction of said fan and perpendicular thereto, said fan assembly comprising a wall element for delimiting an evaporator in said refrigerator, said wall element having a mounting opening suitable for mounting said fan and projecting edges in the direction of said fan, said fan assembly further comprising an isolator and a locking element characterized in that; said isolator comprises a first abutment means against which said first outer wall of said fan is leanable such that a second abutment means of said isolator confine said first outer wall within said isolator and, said locking element is engageable with said projecting edges such that said isolator physically separates said first outer wall from said wall element and said locking element, wherein said first abutment means is a circular abutment supporting outer surface of said first outer wall in a contact relationship.

2. The fan assembly for a refrigerator as set forth in claim 1 wherein said fan case has a square-shaped form.

3. The fan assembly for a refrigerator as set forth in claim 1 wherein said second abutment means is a corner support supporting inner surface corners of said first outer wall in a contact relationship.

4. The fan assembly for a refrigerator as set forth in claim 1 wherein outer surfaces of said isolator extending parallel to the axial direction of said fan are fully enclosed by said projecting edges of said wall element.

5. The fan assembly for a refrigerator as set forth in claim 1 , wherein said projecting edges comprises a locking opening with which a locking end of said locking element is engageable such that said projecting edges are at least partially enclosed by said locking element.

6. The fan assembly for a refrigerator as set forth in claim 5 wherein said projecting edges are designed in the form of a square with each edge having a locking opening lockable by a locking end of said locking element.

7. The fan assembly for a refrigerator as set forth in claim 1 wherein said second outer wall of said fan is enclosable by a polystyrene member in its entirety.

8. The fan assembly for a refrigerator as set forth in claim 2 , wherein said first abutment means is a circular abutment supporting outer surface of said first outer wall in a contact relationship.

9. The fan assembly for a refrigerator as set forth in claim 2 , wherein said second abutment means is a corner support supporting inner surface corners of said first outer wall in a contact relationship.

10. The fan assembly for a refrigerator as set forth in claim 8 wherein said isolator's outer surfaces extending parallel to the axial direction of said fan are fully enclosed by said projecting edges of said wall element.

11. The fan assembly for a refrigerator as set forth in claim 9 wherein said isolator's outer surfaces extending parallel to the axial direction of said fan are fully enclosed by said projecting edges of said wall element.

12. The fan assembly for a refrigerator as set forth in claim 3 , wherein said projecting edges comprises a locking opening with which a locking end of said locking element is engageable such that said projecting edges are at least partially enclosed by said locking element.

13. The fan assembly for a refrigerator as set forth in claim 9 , wherein said projecting edges comprises a locking opening with which a locking end of said locking element is engageable such that said projecting edges are at least partially enclosed by said locking element.

14. The fan assembly for a refrigerator as set forth in claim 4 , wherein said projecting edges comprises a locking opening with which a locking end of said locking element is engageable such that said projecting edges are at least partially enclosed by said locking element.

15. The fan assembly for a refrigerator as set forth in claim 11 , wherein said projecting edges comprises a locking opening with which a locking end of said locking element is engageable such that said projecting edges are at least partially enclosed by said locking element.

16. The fan assembly for a refrigerator as set forth in claim 5 , wherein said second outer wall of said fan is enclosable by a polystyrene member in its entirety.

17. The fan assembly for a refrigerator as set forth in claim 12 , wherein said second outer wall of said fan is enclosable by a polystyrene member in its entirety.

18. The fan assembly for a refrigerator as set forth in claim 14 , wherein said second outer wall of said fan is enclosable by a polystyrene member in its entirety.
