STOREROOM AND REFRIGERATOR FOR STERILIZING FLOATING BACTERIA AMONG COOL AIR IN STORAGE CHAMBER

摘要

PURPOSE: A storage chamber and a refrigerator are provided to sterilize bacteria efficiently by contacting ion to floating bacteria among cool air with simple structure without earth. CONSTITUTION: A refrigerator body(1) is composed of a refrigerator compartment(2), a freezer compartment(3), and a vegetable compartment(4), and divided by partition parts(6a,6b). An isolation chamber(5) is installed in the lower part of the refrigerator compartment, and a case(7) is moved back and forth. An ion generating chamber(45) is formed in the rear part of the refrigerator compartment. Cold air is streamed from the refrigerator compartment to the ion generating chamber via a cold air return port(10), and a needle electrode is arranged in the upper part of the ion generating chamber. Plus ion and minus ion are radiated in parallel with cold air by corona discharge in applying voltage to the needle electrode to reduce loss of ion from collision with the wall, and sterilization effect is improved by contacting ion to cold air for a long time.
