Patent Searching and Data


Title:
REFRIGERATOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/237968
Kind Code:
A1
Abstract:
A refrigerator (100) comprises a housing, a refrigerating liner provided in the housing, a foamed layer (3) provided between the refrigerating liner and the housing, and a guide tube (40) extending inwards from an edge of the housing and buried in the foamed layer (3). The guide tube (40) comprises a rigid tube (4) and a flexible tube (5) connected to each other. An end of the rigid tube (4) located away from the flexible tube (5) is arranged close to the edge of the housing. The strength of the flexible tube (5) is lower than the strength of the rigid tube (4). During a foaming process of the refrigerator, a foaming material is discharged from the flexible tube (5) and filling is performed. Since the strength of the flexible tube (5) is lower than the strength of the rigid tube (4), as the foaming material gradually increases, the foaming material presses the flexible tube (5), such that a certain gap is formed between the flexible tube (5) and the housing or the liner. When the refrigerator is formed and starts operating, the flexible tube (5) is completely buried in the foamed layer (3). Therefore, the amount of cold energy that can be transferred is limited, thereby preventing condensation from occurring at a position on the housing of the refrigerator corresponding to the guide tube (40).
