DEVICE FOR PREVENTING DIFFUSION OF OIL OF VACUUM REFRIGERATOR

摘要

PURPOSE: A device for preventing diffusion of oil of vacuum refrigerator is provided to keep a food storage compartment vacuous to prevent oxidation of stored food and to intercept foreign matters diffuse and flow into the food storage compartment due to difference of density to keep the food clean. CONSTITUTION: A vacuum refrigerator includes a vacuum chamber(30); a vacuum pump(40); and an oil diffusion preventive device. The vacuum chamber is placed on a cold air passage and has a space part to store food therein. The vacuum pump discharges air in the vacuum chamber to outside to keep vacuum in the vacuum chamber fixed. The oil diffusion preventive device prevents gaseous oil generated in the vacuum pump from diffusing into the vacuum chamber due to difference of density. The oil diffusion preventive device includes an oil absorption filter(50) and a fixing unit. The oil absorption filter is placed on a connecting hose(41) connecting the vacuum chamber and the vacuum pump to absorb gaseous oil generated in the vacuum pump. The fixing unit is placed on the connecting hose to fix the oil absorption filter.
