Description

Technical Field

[0001] The utility model relates to the technical field of air outlet covers, in particular to an air outlet cover for a refrigerator. Background Art

[0002] The air outlet cover is an important part of the exhaust system. The air outlet cover can capture harmful substances, control the flow of polluted gas, and prevent harmful substances from diffusing into the indoor air. Through the air flow movement at the local air outlet cover opening, harmful substances can be directly captured at the location where they are emitted or their diffusion in the workshop can be controlled, ensuring that the concentration of harmful substances in the indoor working area does not exceed the requirements of the national health standard.

[0003] Since a refrigerator needs to discharge heat during operation, an air outlet cover is also provided on the back of the refrigerator. Most of the existing refrigerator air outlet covers do not have an insect-proof net or are not easy to disassemble. For example, in the utility model with the patent number CN209558764U, although the provided air outlet cover is beneficial for exhausting air, it does not have an insect-proof device inside. Since the refrigerator is in the same position for a long time, this causes some insects to enter the interior of the refrigerator, eventually resulting in damage to the internal circuits of the refrigerator, and the air outlet cover is also not easy to disassemble.
