Description

A quick-release structure for a refrigerator compartment damper

Technical Field

The utility model relates to the technical field of refrigerator refrigeration chamber air doors, in particular to a refrigerator refrigeration chamber air door quick-detachable structure.

Background Art

A refrigerator is composed of a door, a box, a control system, a refrigeration system and various interior parts. Usually, a refrigerator has at least two compartments, namely, a refrigerator and a freezer. Some also have a variable temperature chamber, a flash freezing chamber, etc. To achieve precise temperature control in each compartment, it is necessary to control each compartment to meet the temperature requirements of different compartments. The temperature requirements and sizes of each compartment are different, and the time to reach the temperature is also different. This requires the damper to switch between the compartments, that is, when a compartment reaches the temperature, the damper is closed; when the compartment temperature does not reach the requirement, the damper is opened.

The damper often freezes due to condensation, which affects its normal operation. At this time, it needs to be disassembled for maintenance. Common damper components are basically installed in the cold storage room with bolts. Therefore, screwdrivers and other components are required for disassembly and assembly. The small space in the cold storage room and poor sight affect disassembly and assembly. Secondly, some damper components are installed by inserting the card blocks into the corresponding card slots. The disassembly and assembly process may cause the card blocks to break and affect the stability of subsequent installation.

Both of the above methods have certain shortcomings. In order to address the above shortcomings, the present application proposes a refrigerator refrigerator compartment damper quick-release structure.
