Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator door hinge structure and a refrigerator. Background Art
[0002] In the prior art, most freezer door opening methods are to connect the freezer door and the box body with a chain, and the door body rotates around the chain axis. The upper hinge and the lower hinge of the freezer are traditionally placed at the upper right corner and the lower right corner of the box body and fixed with screws.
[0003] This structure has the following shortcomings: since the outlet wires of the freezer cabinet are also outlets at the hinges while the hinges are fixed, the foaming mold will give way to avoid the cables during foaming, resulting in the top hinge installation surface not being flat, which in turn causes the hinge to be offset during installation, and ultimately causes the outlet door to be offset, the door and the freezer body to be misaligned, and the seal between the door and the freezer is not tight, resulting in cold leakage. In addition, in order to reduce the weight of the freezer and to provide insulation, a foaming agent must be filled during assembly of the freezer. Since the ambient temperature sensor is placed in the top wall of the freezer, during production, the ambient temperature sensor often fails, is squeezed and deviated, or has its service life shortened due to the filling of the foaming agent.
