Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator door seals, in particular to a refrigerator door seal capable of reducing heat load. Background Art

[0002] The refrigerator door seal is usually a strip made of soft rubber or silicone material, installed on the edge or around the refrigerator door to ensure that the refrigerator door can be effectively sealed when it is closed. Its main function is to prevent the loss of cold air and prevent the outside air from entering the refrigerator, thereby maintaining a stable temperature inside the refrigerator. In addition, the refrigerator door seal can effectively prevent dust, odors and other substances from entering the refrigerator, keeping the refrigerator clean and hygienic, and preventing food from being contaminated. If the refrigerator door seal is damaged or aged, it will cause the cold air to leak out continuously, affecting the stability of the temperature inside the refrigerator. Common materials for refrigerator door seals include polyvinyl chloride, acrylonitrile-butadiene-styrene copolymer and silicone, among which reducing heat load is an important function of refrigerator door seals.

[0003] For example, the Chinese patent "A New Type of Refrigerator Door Seal" with announcement number CN209013596U includes a magnetic stripe bag, an inner air bag, an auxiliary air bag and a sealed cabin, the inner air bag is located on the inner side of the magnetic stripe bag, one end of the auxiliary air bag is connected to the magnetic stripe bag and the inner air bag, and the other end is connected to the sealed cabin, a fixed supporting rib is provided on the top of the sealed cabin, a cover lining sealing wing extends outward from the connection between the auxiliary air bag and the sealed cabin, the inner air bag is provided with an arc-shaped auxiliary sealing wing and a second sealing winglet, the second sealing winglet is located on the inner side of the auxiliary sealing wing, and after the door seal is assembled, the auxiliary sealing wing, the second sealing winglet and the refrigerator door body form a sealed chamber, a sealing wing snap is also provided on the inner side of the curved side of the arc-shaped auxiliary sealing wing, a first sealing winglet is provided on the inner side of the auxiliary air bag, and after the door seal is assembled, the first sealing winglet, the second sealing winglet, the inner air bag cavity wall, the auxiliary air bag cavity wall and the refrigerator door body form a sealed chamber, and the edge of the auxiliary air bag cavity is a retractable suction rib.

[0004] Although the above-mentioned prior art can achieve sealing between the refrigerator door and the cabinet body, in actual use, on the one hand, the door seal is prone to rubber fatigue after long-term use. When in use, the door seal fixes the cabinet body and the cabinet door to each other through magnetic force. When the cabinet door is opened, the door seal detaches from the cabinet body, causing the door seal to lose elasticity, thereby reducing the thermal load of the door seal. On the other hand, the door seal is not convenient to disassemble and assemble. When the door seal is replaced after a period of use, the fixing structure needs to be removed, which causes the fixing structure to become loose after repeated use, thereby reducing the sealing of the door seal. Therefore, it does not meet the existing needs. In this regard, we propose a refrigerator door seal that can reduce the thermal load. Utility Model Content

[0005] The utility model aims to provide a refrigerator door seal capable of reducing heat load, so as to solve the problems in the above background technology that the door seal is prone to rubber fatigue after long-term use and the door seal is not convenient to disassemble and assemble.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a refrigerator door seal capable of reducing heat load, comprising a refrigerator door; and further comprising:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can ensure a certain support between the second sealing strip and the first sealing strip through the rubber rod and the rubber air cushion. When the box door is rotated, the box door is adsorbed on the box body through the first magnetic strip, and the first sealing strip is squeezed at the same time, so that the rubber rod and the rubber air cushion between the first sealing strip and the second sealing strip are compressed and deformed. After the extrusion is weakened, the rubber rod and the rubber air cushion are reset. During the resetting process of the rubber and the rubber air cushion, the first sealing strip is restored to its original position, so that the adsorption between the first sealing strip and the box body is tighter. When the box door is opened, the second sealing strip first pulls the rubber rod and the rubber air cushion, so that the rubber rod and the rubber air cushion are stretched and deformed, and at the same time, the first sealing strip is driven to detach from the box body. After the first sealing strip is detached from the box body, the rubber rod and the rubber air cushion are reset and the first sealing strip is restored to its original position, so as to avoid rubber fatigue of the door seal after multiple opening and closing of the box door, thereby reducing the heat load of the door seal.

[0017] 2. The utility model can quickly disassemble and assemble the door seal through the bolts and the fixing seat. When replacing the door seal, first rotate the bolt to make the bolt move outward in the threaded hole through the external thread until the bolt is disengaged from the threaded hole. At this time, the door seal is adsorbed on the box door through magnetic force. Then the door seal is removed from the box door, and then the new door seal is fixed in the positioning groove. At this time, the fixing hole on the fixing seat corresponds to the position of the threaded hole. Then align the bolt with the fixing hole and push it into the fixing hole until one end of the bolt contacts the opening of the threaded hole. At this time, rotate the bolt again to make the bolt move toward the inside of the threaded hole through the external thread until the bolt enters the inside of the threaded hole and fixes the door seal through the thread of the bolt, thereby simplifying the disassembly and assembly steps of the door seal and improving the sealing performance of the door seal.

[0018] 3. The utility model can quickly position the door seal during installation through the second magnetic strip and the positioning groove. When replacing the door seal, align the new second sealing strip with the opening of the positioning groove and push the second sealing strip into the positioning groove. At this time, the second magnetic strip on the second sealing strip is adsorbed by the metal of the door through magnetic force, so that the second sealing strip is adsorbed and fixed in the positioning groove. After the second sealing strip is positioned and fixed, the fixing hole on the fixing seat corresponds to the hole position of the threaded hole, which is convenient for rapid positioning when replacing the door seal, thereby improving the replacement efficiency of the door seal.
