得る。In this method of manufacturing a refrigerator outer box, the heat dissipation portion 3b of the condensing pipe 3 is heated on the upper surface which is the inner surface after bending of the flat plate-shaped cabinet member 1 in which the U-shaped groove portion 2 is formed upright on at least the front flange portion of the metal plate. The aluminum foil tape 5 having good conductivity is attached, and the dew condensation preventing portion 3a of the condensing pipe is fitted into the U-shaped groove portion 2 of the cabinet member 1. And
One U-shaped bend portion 6 extends vertically from the U-shaped groove portion 2 on one of the left and right sides of the cabinet member 1, and the notch 7 of the side wall provided in the U-shaped groove portion 2 on the other side of the left and right sides U
The character-shaped bend portion 8 extends in parallel along the side plate 1a of the cabinet member 1. Further, the aluminum foil tape is not attached to the side near the center of the cabinet member 1 of the U-shaped bend portion 8 formed substantially symmetrically with the U-shaped bend portion 6, and the notch portion 7 is formed.
Of the U-shaped bend portion 8 is attached to the cabinet member 1 by an aluminum foil tape 5 and fixed to the cabinet member 1 so that the U-shaped bend portion 8 functions as a heat radiating pipe. In this state, the flat plate-shaped cabinet member 1 and the condensing pipe 3 are simultaneously bent and formed to have a front groove shape in which both side plates 1a and top plate 1b are continuous. As shown in FIG. 3, the bending radius r of the bent portion of the cabinet member 1 and the bent radius R of the condensing pipe 3 are different from each other to prevent deformation such as crushing of the condensation pipe during bending. Therefore, the dimension X corresponding to the deviation is added in advance to the predetermined interval of the root portions of the U-shaped bend portions 6 and 8. At the appropriate time after the bending and molding of the cabinet member 1, the bottom plate and the back plate are attached to form the outer box 4 of the refrigerator as shown in FIG. 8, and then the inner box is fitted to the bottom box 4 between them. A foam body is filled with a heat insulating material to obtain a refrigerator body.

役割をほとんど果せないという問題点があった。[Problems to be Solved by the Invention] An outer box of a refrigerator obtained by a conventional manufacturing method has a configuration in which a part of a condensing pipe 3 is fitted in a U-shaped groove portion 2 provided in a front flange portion of a cabinet member 1. Then, a dimension X corresponding to a deviation due to a difference in radius of curvature between the bending radius r of the flat cabinet member 1 and the bending radius R of the condensing pipe 3.
In addition to the U-shaped bend portion 6 of the partition wall portion and the U-shaped bend portion 8 extending along the side plate 1a from the notch portion 7 of the one side wall of the U-shaped groove portion 2 provided in a substantially symmetrical position in advance. Since the condensing pipe 3 is arranged on the upper surface of the cabinet member 1, the notch 7 reduces the strength of the cabinet, and the U-shaped bend 8 extending from the notch 7 along the side plate 1a has a curvature. Due to the absorption of the difference in radius, the side close to the bend cannot be fixed to the cabinet member 1 with aluminum foil tape or the like,
There is a problem that it is difficult to adhere to the member 1 and the role as a heat radiation pipe can hardly be fulfilled.
