Abstract

A fan assembly for a refrigeration appliance includes a fan for circulating air within a compartment of the refrigeration appliance. The fan includes a frame. A housing is provided for mounting the fan. The housing includes a plate with an opening extending through the plate. A plurality of walls extends from a surface of the plate. A first retaining member extends in a direction generally parallel to a surface of the plate and is disposed proximate the opening for hindering movement of the fan in a direction generally perpendicular to a surface of the plate. The plurality of walls and the first retaining member define a pocket for receiving the frame. A vibration damping member is provided for allowing the fan to vibrate relative to the housing and for hindering the transmission of vibrations from the fan to the housing.

First claim

What is claimed is:

1. A fan assembly for a refrigeration appliance, the fan assembly comprising:
a fan for circulating air within a compartment of the refrigeration appliance, the fan including a frame;
a housing for mounting the fan, the housing comprising:
a plate with an opening extending through the plate;
a plurality of walls extending from a surface of the plate;
a first retaining member extending in a direction generally parallel to a surface of the plate and disposed proximate the opening for hindering movement of the fan in a direction perpendicular to a surface of the plate; and
a second retaining member wherein one of the first retaining member and the second retaining member is disposed in the opening in the plate and the other of the first retaining member and the second retaining member is attached to one of the plurality of walls,
wherein the plurality of walls and the first retaining member define a pocket for receiving the frame; and

a vibration damping member for allowing the fan to vibrate relative to the housing and for hindering transmission of vibrations from the fan to the housing.

2. The fan assembly according to claim 1 , wherein the plurality of walls includes a horizontal lower wall and two vertical side walls extending from opposite ends of the horizontal lower wall, upper ends of the vertical side walls defining an opening for receiving the fan into the pocket.

3. The fan assembly according to claim 1 , wherein the first retaining member is attached to one of the plurality of walls.

4. The fan assembly according to claim 1 , wherein the first retaining member is fixed relative to one of the plurality of walls.

5. The fan assembly according to claim 1 , wherein the vibration damping member is a gasket made of a closed-cell foam material.

6. The fan assembly according to claim 1 , wherein the fan is secured in the housing without additional fasteners.

7. The fan assembly according to claim 1 , wherein the vibration damping member is attached to at least one of the frame of the fan and the housing.

8. The fan assembly according to claim 1 , wherein the housing is mounted to a wall of the compartment of the refrigeration appliance.

9. The fan assembly according to claim 1 , wherein the plate of the housing is a wall of the compartment of the refrigeration appliance.

10. A refrigeration appliance for storing articles in a refrigerated environment, the refrigeration appliance comprising:
a first compartment;
an evaporator; and
a fan assembly for supplying cooling air from the evaporator to the first compartment, the fan assembly comprising:
a fan for circulating the cooling air, the fan including a frame;
a housing for mounting the fan, the housing comprising:
a plate with an opening extending through the plate;
a plurality of walls extending from a surface of the plate; and
a first retaining member extending in a direction generally parallel to a surface of the plate and disposed proximate the opening for hindering movement of the fan in a direction generally perpendicular to a surface of the plate,
wherein the plurality of walls and the first retaining member define a pocket for receiving the frame; and

a vibration damping member for allowing the fan to vibrate relative to the housing and for hindering transmission of vibrations from the fan to the housing.

11. The refrigeration appliance according to claim 10 , wherein the plurality of walls includes a horizontal lower wall and two vertical side walls extending from opposite ends of the horizontal lower wall, upper ends of the vertical side walls defining an opening for receiving the fan into the pocket.

12. The refrigeration appliance according to claim 10 , wherein the first retaining member is attached to one of the plurality of walls.

13. The refrigeration appliance according to claim 10 , further comprising a second retaining member wherein one of the first retaining member and the second retaining member is disposed in the opening in the plate and the other of the first retaining member and the second retaining member is attached to one of the plurality of walls.

14. The refrigeration appliance according to claim 10 , wherein the first retaining member is fixed relative to one of the plurality of walls.

15. The refrigeration appliance according to claim 10 , wherein the vibration damping member is a gasket made of a closed-cell foam material.

16. The refrigeration appliance according to claim 10 , wherein the fan is secured in the housing without additional fasteners.

17. The fan assembly according to claim 10 , wherein the vibration damping member is attached to at least one of the frame of the fan and the housing.

18. The fan assembly according to claim 10 , wherein the housing is mounted to the first compartment.

19. The fan assembly according to claim 10 , wherein the plate of the housing is a wall of the first compartment.
