Abstract

The utility model discloses an exhaust structure of a refrigerator, which comprises a refrigerator body frame assembly and a gas flow guide assembly. The box body frame assembly consists of an inner container, a shell and a lower rib plate, and the gas flow guide assembly comprises a bottom plate layer and a baffle plate layer which are arranged in parallel, and the bottom plate layer and the baffle plate layer form a closed exhaust channel through an edge bonding layer. The exhaust channel is provided with an air inlet and a tail end exhaust hole, and the channel height is smaller than the critical flow thickness of the foaming material. The two sides of the bottom of the box body are provided with L-shaped angle plates, and the top end of the box body is provided with a glue injection baffle plate with a glue injection port to form a glue injection cavity. According to the utility model, a directional exhaust path is formed through the double-layer plate structure, gas is intensively exhausted through the channels during foaming, and foaming materials are blocked due to the narrow channels and the solidification self-locking effect, so that the problem of air trapping caused by easy blockage of the traditional exhaust holes is solved, and the phenomenon of material leakage is avoided. The baffle layer is provided with an anti-stripping bulge, so that the structural stability is ensured. The structure does not need complex micropore processing, effectively reduces the production cost and improves the foaming quality.
