Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator door seals, in particular to a novel door seal structure for refrigerators. Background Art

[0002] The freezer door seal is a sealing component installed on the edge of the freezer door. Its main functions are: (1) Sealing and heat preservation: effectively blocking outside air from entering the freezer, reducing the loss of cold, and maintaining a low temperature environment inside the freezer. (2) Preventing frost and condensation: reducing the gap between the freezer door and the cabinet body, preventing moisture from entering, and reducing the possibility of frost and condensation. (3) Energy saving: improving the energy efficiency of the freezer and reducing energy consumption through good sealing. Among them, the commonly used materials for freezer door seals are the following: (1) Rubber: such as EPDM rubber, which has good elasticity and sealing performance. (2) Silicone rubber: good low temperature resistance and strong flexibility. (3) Plastic: such as PVC, which has certain toughness and strength. However, the existing door seal components for freezers have low working reliability. Especially after long-term use, the door seal will be squeezed, crushed or cracked, thereby reducing its overall sealing stability and having a greater impact on the refrigeration performance of the freezer.
