Abstract

A refrigeration appliance comprises a fan mounting assembly mountable to a liner of a cabinet. The fan mounting assembly comprises a bracket, a first member of a first snap coupling on the bracket for receiving a corresponding second member of the first snap coupling on an evaporator coil cover, and a mounting flange having a first member of a snap lock extending from the bracket for mounting the fan mounting assembly to the liner of the cabinet. An evaporator coil cover for mounting to the fan mounting assembly comprises a second member of the first snap coupling allowing the evaporator coil cover to be coupled to the fan mounting assembly, and a first slot. An air tower assembly mountable to the fan mounting assembly through the first slot comprises a second member of a second snap coupling and a second member of a third snap coupling.

First claim

What is claimed is:

1. A refrigeration appliance comprising:
a cabinet;
a fan inside the cabinet;
a fan mounting assembly mountable to a liner of the cabinet, wherein the fan mounting assembly comprises:
a bracket enclosing the fan and a fan motor having an opening for fan blades;
a mounting flange extending from the bracket for mounting the fan mounting assembly to the liner of the refrigeration appliance cabinet, said mounting flange comprising a snap lock including a first member for receiving a corresponding second member of the snap lock mounted on the liner of the refrigeration appliance cabinet,
wherein the first member of the snap lock is a female dovetail comprising a narrow upper portion, two arms defining female dovetail slots, and a snap tongue including a nose, said snap tongue extending from the narrow upper portion and configured to lock the bracket to the male dovetail in a vertical direction and the second member of the snap lock is a male dovetail projecting from the liner into the refrigeration appliance cabinet, and
wherein, when snapped together, the male dovetail partially overlaps the two arms of the female dovetail, the narrow upper portion of the female dovetail slides behind the male dovetail, and the nose of the snap tongue of the female dovetail rides over the male dovetail until the nose of the female dovetail engages a bottom of the male dovetail to inhibit vertical movement of the mounting flange, such that the female dovetail is captured by the male dovetail projection on three sides.

2. The fan mounting assembly of claim 1 , wherein the snap tongue is configured to lock the bracket to the male dovetail in a vertical direction.

3. The fan mounting assembly of claim 1 , wherein the male dovetail is mounted on the liner of the refrigeration appliance cabinet by a toggle-lock.

4. The fan mounting assembly of claim 1 , wherein the bracket further comprises a base panel for receiving the fan blades and a first snap coupling provided on the base panel, wherein the first snap coupling on the fan mounting assembly comprises a notched tab and a snap hole formed on the evaporator coil cover.

5. The fan mounting assembly of claim 1 , wherein the bracket further comprises a a first member of a second snap coupling provided on the base panel for receiving a corresponding second member of the second snap coupling on an air tower assembly, and allowing the air tower assembly to be coupled to the fan mounting assembly.

6. The fan mounting assembly of claim 5 , wherein the first member of the second snap coupling is a snap hole and the second member of the second snap coupling is a mounting hook.

7. The fan mounting assembly of claim 1 , further comprising a first member of a third snap coupling for receiving a corresponding second member of the third snap coupling on the air tower assembly, and allowing the air tower assembly to be coupled to the fan mounting assembly.

8. The fan mounting assembly of claim 7 , wherein the first member of the third snap coupling is a snap clip and the second member of the second snap coupling is a snap hole.

9. The fan mounting assembly of claim 1 , further comprising a screw hole corresponding in position to a tapped hole on the liner of the refrigeration appliance cabinet for securing the fan mounting assembly to the liner.

10. The fan mounting assembly of claim 1 further comprising a middle plate secured at a position between the fan motor and a base panel of the fan mounting assembly to thereby inhibit the contact of the fan motor and the evaporator coil cover.

11. The fan mounting assembly of claim 1 , wherein the bracket is configured to be snapped to the male dovetail by first positioning the male dovetail behind the snap tongue of the female dovetail and in front of the female dovetail slots, and then sliding the bracket downwards until the narrow upper portion of the female dovetail slides behind the male dovetail.
