Vacuum sterilization frost-free refrigerator

The invention provides a vacuum sterilization frost-free refrigerator and relates to refrigerator products. The vacuum sterilization frost-free refrigerator is suitable for occasions requiring a refrigerator, a disinfection cabinet and the like. Only a defrosting device is additionally arranged in a frost-free refrigerator sold in the current market and frost is still generated. By the adoption of the vacuum sterilization frost-free refrigerator, a contact portion between a refrigerator body and a refrigerator door can be completely and tightly sealed, steam in air cannot flow into the refrigerator, the condition for frost generation in the refrigerator is eliminated, and the refrigerator is truly a frost-free refrigerator; and a vacuumization component system is arranged in the refrigerator, the interior of the refrigerator is dry, bacteria cannot be bred, and the freshness preservation period of food in the refrigerator can be prolonged. The vacuum sterilization frost-free refrigerator is composed of main components of the refrigerator body, the refrigerator door, anti-corrosion refrigerator door gas and liquid sealing devices, a vacuumization component system and a refrigeration system. The vacuum sterilization frost-free refrigerator is characterized in that the anti-corrosion refrigerator door gas and liquid sealing devices are arranged in the refrigerator body and the refrigerator door; air suction holes are formed in food storage chambers of the refrigerator to be connected with the vacuumization system; and the refrigeration system is further arranged in the refrigerator body, so that the vacuum sterilization frost-free refrigerator is formed.
