After the separation of the foam jig 16 again, the cabinet assembly resulting from the foaming operation is secondary to the position of each assembly formed by the foam jig 16 as shown in FIG. To wealth

Freezer compartment evaporator 17 bent into a shape, freezer compartment evaporator cover 18, inlet of the freezer compartment evaporator 17, outlet pipe freezer compartment evaporator strip 20, refrigerator compartment evaporator 22, capillary tube 23, suction tube 12, sap Machine 24, the refrigerator back plate 26, etc. are completed in order to sequentially assemble all the parts related to the refrigerant flow path of the refrigerator as in the conventional case because the present invention assembled all the parts after foaming the insulating material. When all the parts are assembled before foaming the heat insulating material and then foaming the heat insulating material, when the defect occurs in the heat insulating material foaming process, which is various problems, the refrigerant flow path-related parts are buried or contacted with the foam, which is impossible to recover. As the parts can be recovered by assembling the parts after foaming the heat insulating material, it is possible to reduce the material loss in case of defects in the manufacturing process of the refrigerator. In addition, when there is a leak in the refrigerant flow path buried or in contact with the foam during use, it is impossible to replace the parts, so the entire refrigerator is discarded. It is done.
