ABSTRACT:
A multi-function apparatus for use in a refrigerator generates a plurality of positive or negative D.C. voltages to a pointed electrode structure and a strip shaped electrode structure in order to generate corona discharge, thereby sterilizing/deodorizing air in the refrigerator's compartments, and furthermore a separate positive or negative voltage is applied to an ionizing electrode to generate positive or negative ions in the air, thus preserving the freshness of stored foodstuffs for an extended period of time.
