Abstract
A deodorizing element (10) for use in a refrigerator (1). The element acts to remove food odors from the air circulating through the refrigerator which has a refrigeration system (5) by which air is circulated throughout a food storage compartment (2-4). The deodorizing element comprises a metal rod (14) at each end of which are electrical connections (16a, 16b) for connecting the heating element into an electrical circuit by which current is drawn through the rod. A layer (24) of a coating material is formed on the outer surface of the rod. This coating material is an odor absorbing material which is activated by the heat generated when current flows through the heating rod. The heating rod is mounted in an air circulation path of the refrigeration system by which air flowing through the system is drawn over the heating element and odors in the air are absorbed by the coating material.
