Background

The air duct system of the existing single-system air-cooled refrigerator with the upper refrigerating and the lower refrigerating comprises a freezing air duct, a refrigerating air duct and a bubble layer air duct. The freezing air duct and the refrigerating air duct are mainly responsible for air distribution of freezing and refrigerating, and the bubble layer air duct is mainly responsible for conveying cold air in the evaporator bin to other compartments and circulating hot air which completes heat exchange in the compartments to the evaporator bin for heat exchange. The foam layer air duct is pre-installed in the foaming box body before the foaming of the refrigerator, and the freezing air duct and the refrigerating air duct are assembled in the freezing chamber and the refrigerating chamber after the foaming of the box body is finished. Most of the existing bubble layer air channels are plastic parts, the preassembly assembly process is complex, and the bubble layer air channels are fixed on an air outlet and return air of a box liner by using adhesive tapes, so that the size of the air outlet is ensured to be consistent with the design size.

The design of the existing foam layer air duct has the defects of complex preassembly and assembly process, long time consumption, high cost, foaming leakage and air duct efficiency reduction due to the fact that air duct parts cannot be installed in place.
