REFRIGERATOR WITH VALVE FOR PRESSURE EQUALISATION

摘要

FIELD: personal use articles. ^ SUBSTANCE: refrigerator has body with the main body frame and door, which surround cooled internal chamber. Valve for pressure equalisation passes through body wall to assist in air inflow from surrounding space into inner chamber and to block air outflow from inner chamber. Parallel to valve for pressure equalisation there is a channel arranged in body wall to let air through in two directions. Throughput capacity of channel is less than throughput capacity of valve in conducting direction and is more than throughput capacity of valve leakage circuit for equalisation of pressure in locking direction. ^ EFFECT: invention eliminates chance of valve freezing. ^ 10 cl, 7 dwg
