Mounting arrangement for a refrigerator fan

A mounting arrangement for a refrigerator fan comprising an electric motor, to whose shaft is affixed a propeller with an axial flow passing through a refrigerated air outlet provided through an internal divisional wall of the refrigerator, comprising:

• a support frame having a marginal portion external to the contour of rotation of the propeller and incorporating a central hub in which is affixed the electric motor;
• a flexible support in the form of an annular flange presenting, in a single piece:
• an outer portion, which is peripherally and removably affixed to the internal divisional wall, along the contour of the refrigerated air outlet;
• an inner portion provided with a central opening and with elastic retaining means, which are removably locked to the marginal portion of the support frame in a condition in which said marginal portion is axially aligned with the central opening of the flexible support;
• and
• an annular membrane portion interconnecting the outer portion and the inner portion, in order to allow for small relative axial and radial displacements therebetween,
• wherein the outer portion of the flexible support is provided with a peripheral groove designed to contact an edge of the internal divisional wall that defines the contour of the refrigerated air outlet.
