Description

Technical Field

[0001] This utility model belongs to the field of refrigerator-related technology, specifically relating to a refrigerator door with an interchangeable door panel. Background Technology

[0002] With the continuous improvement of people's living standards, refrigerators, as an important household appliance, play an indispensable role in daily life. The main function of a refrigerator is to extend the shelf life of food by maintaining a low temperature environment, and the sealing performance of the refrigerator door is crucial to achieving this function. Currently, most refrigerator doors on the market use traditional sealing methods, among which frame-type sealing gaskets are one of the most common sealing components. However, in actual use, frame-type sealing gaskets have some problems;

[0003] On the one hand, frame-type gaskets are affected by their own aging. Over time, the gasket material gradually ages, hardens, and loses elasticity, leading to a decline in sealing performance. During long-term use, the gasket may develop cracks or deformation, further weakening its sealing effect. On the other hand, temperature differences also adversely affect the sealing performance of frame-type gaskets. When there is a large temperature difference between the inside and outside of the refrigerator, the gasket will be subject to thermal expansion and contraction. During repeated thermal expansion and contraction, the gasket may loosen or deform, easily leading to leakage problems.

[0004] Furthermore, traditional refrigerator door sealing methods have certain limitations in the design of replaceable door panels. As consumers' demands for personalization continue to increase, refrigerator doors with replaceable panels are becoming increasingly popular. However, existing replaceable door refrigerator doors often fail to meet users' sealing performance needs, especially when faced with aging or temperature fluctuations, making them more prone to poor sealing.
