Claims

[Scope of Claim for Utility Model Registration], 1. A bushing that penetrates between the inner box and the back plate of the refrigerator is provided, and the surroundings of the bushing are filled and fixed with a heat insulating material such as polyurethane foam, and In a refrigerator in which the refrigerant return pipe connecting the evaporator and compressor mounted on the surface, that is, the suction pipe, is guided from the inside of the refrigerator to the outside through the bushing, the bushing is provided with a fin for sealing cold air. The refrigerator features a bushing structure that passes through the suction pipe. 2. The fins provided on the penetrating bushing are thinner than the plate thickness of the bushing body, and in order to facilitate the penetration of the suction pipe, grooves are provided radially in the center of the fin, and a hole is provided in the center of the fin, and the hole A suction pipe bushing structure for a refrigerator according to claim 1, wherein the cut grooves are arranged radially around the center. 3. A suction pipe bushing structure for a refrigerator according to claim 1, wherein the through bushing structure is divided into two parts, each of which has a fin to provide a two-stage cold air seal.
