  • Thermal insulation cabinet, and method for preparing same and refrigerator having same
    Patent number: 11879585
    Abstract: A thermal insulation cabinet and a manufacturing method therefor, and a refrigerator having same. The manufacturing method for the thermal insulation cabinet comprises the following steps: pre-assembling a shell having a vacuum insulation panel attached to the inside, into a cabinet shell; heating the inside of the cabinet shell; and injecting a foaming material between the cabinet shell and an inner liner for foaming. According to the present invention, the inside of the cabinet shell is heated, such that the inner surface of the shell can reach a target temperature required for foaming, thereby reducing or avoiding a surface crusting phenomenon, and improving a thermal insulation effect of the thermal insulation cabinet.
