Refrigerator, wind blocking strip used for refrigerator and manufacturing method thereof

Abstract

The invention discloses a refrigerator, a wind blocking strip used for the refrigerator and a manufacturing method thereof. The manufacturing method of the wind blocking strip used for the refrigerator comprises the steps that first, rigid plastic is added into a first extruding machine, a thermoplastic polyester elastomer (TPEE) modified material is added into a second extruding machine; second, the molten and plasticized rigid plastic and the TPEE modified material are collected at machine heads of the first extruding machine and the second extruding machine, and the formed wind blocking strip is obtained; and third, the formed wind blocking strip is shaped and cooled sequentially, and the wind blocking strip used for the refrigerator is obtained. A clamping groove is made of the rigid plastic, a folded edge is made of the TPEE modified material, and through different moulds and a certain process condition, the rigid plastic and the TPEE modified material are extruded together to be manufactured to be the wind blocking strip; because the TPEE modified material has the strength of engineering plastic and the elasticity of rubber, the friction resistant capacity and the elasticity and airtightness at the low temperature of the wind blocking strip are all improved, accordingly the service life of the wind blocking strip is prolonged, and the energy consumption of the refrigerator is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator, a windshield strip for the refrigerator and a manufacturing method thereof. Background technique [0002] The normal operating temperature of the refrigerator freezer in the industry is generally around -15°C, while the ambient temperature outside the refrigerator is generally above 10°C, and the temperature difference between the inside and outside of the refrigerator is large. Condensation is generated, which greatly reduces the energy consumption level of the refrigerator. In order to reduce the loss of energy consumption, a windshield strip is generally arranged in the freezing chamber to improve the sealing ability of the freezing chamber. At present, most of the windshields used in refrigerators are made of PVC material, but due to the low temperature of the freezer, the PVC material itself will harden when it is cold, and cannot achieve a sealing eff...
