Description

Technical Field

[0001] This utility model relates to the field of refrigerator structure technology, and in particular to a refrigeration air duct downward assembly structure. Background Technology

[0002] In the refrigeration system of a frost-free refrigerator, the air duct serves as the core channel for cold air circulation, and the stability of its installation and fixation affects the structural and electrical safety of the refrigerator. Traditional refrigeration air duct fixing typically uses a snap-fit ​​structure to prevent the entire duct from falling off, meeting the basic requirements for duct structural stability and protection of electrical components during refrigerator operation. However, snap-fit ​​fixing methods are prone to over-tightening or over-loosening of the snaps, causing the refrigeration air duct cover to loosen or fall off. Furthermore, after long-term use, the snap-fit ​​structure is susceptible to elastic deformation due to material fatigue, leading to a decrease in clamping strength and affecting the reliability of the air duct fixation.

[0009] The refrigerated air duct foam includes an integrally formed arc-shaped groove structure cover and an extension plate. The extension plate is smoothly connected to the edge of the cover. The front end of the cover wraps around the electric air door cover. The outer side wall of the refrigerated air duct foam is tightly fitted to the inner side wall of the refrigerated air duct cover.

[0010] It also includes a third fixing seat. The extension plate has a positioning hole at one end near the cover body. The refrigerated air duct cover plate has a positioning post. The positioning post is located in the positioning hole. The inner liner has a positioning protrusion.

[0012] The above technical solution has the following beneficial effects:

[0013] This utility model uses a fixed base pre-placed in the placement platform and groove of the refrigerated air supply foam. The fixed base and the air supply foam are integrated by foam molding. The refrigerated air duct cover and electric air door cover are fastened with screws, which replaces the traditional snap-fit ​​method. This avoids the problem of over-tightening / over-loosening of the assembly caused by dimensional deviation. Moreover, the screw connection strength is not affected by material fatigue, effectively preventing the components from loosening or falling off during operation and vibration, and ensuring the long-term stability of the air duct structure.
