[0032] like Figures 1-3 As shown, in this embodiment, the refrigerator's refrigeration air duct structure includes an outer air duct panel 1 and an inner air duct panel 2. The outer air duct panel 1 is made of plastic, and the inner air duct panel 2 is made of foam. The inner air duct panel 2 is located on the inner side, and its overall structure is uneven. To avoid difficulties in tightly connecting the inner air duct panel 2 with other refrigerator components or inconvenience during direct installation, the outer air duct panel 1 is installed on one side of the inner air duct panel 2. The side of the outer air duct panel 1 facing away from the inner air duct panel 2 is flat, facilitating the tight connection between the outer air duct panel 1 and other components. The air duct is tightly sealed, enhancing its airtightness. The flat surface of the outer duct panel 1 serves as the back panel of the refrigerator compartment, meaning it is directly visible after opening the refrigerator door. Since vegetables are frequently placed in the refrigerator compartment, vegetable scraps easily adhere to the back panel. The outer duct panel 1 corrects the uneven structure of the inner duct panel 2, facilitating cleaning. Simultaneously, the plastic outer duct panel 1 supports the foam inner duct panel 2, strengthening the overall structure of the refrigerator's air duct system. Specifically, one side of the outer duct panel 1 has a first edging 101 and a support member 102. The inner side of the first edging 101 has an elastic buckle 103. See details...
