Abstract
Description
Technical Field
[0001] The utility model relates to the field of refrigeration equipment, in particular to a high-strength splicing structure of a refrigerator door frame. Background Art
[0002] The refrigerator's main structure consists of a metal outer shell and a white plastic inner liner. The junction between the white inner liner frame and the metal outer shell is unadorned. To enhance aesthetics, manufacturers have designed aluminum alloy or aluminum-coated plastic profile frames for the white inner liner's frame. However, traditional aluminum alloy or aluminum-coated plastic profile frames often use adhesives for joining. The adhesive's bonding effect weakens over time, potentially degrading the seal and causing cold air to escape from the outer shell. This wastes a significant amount of cold air and affects the refrigerator's performance. Utility Model Content
