2. Description of the Related Art Generally, a refrigerator has a three-layer structure of an inner box, an outer box and a heat insulating material for heat insulation and heat retention. The outer box is defined by connecting a number of iron plates. FIG. 1 is a view showing a conventional outer box connection structure. As shown in FIG. 1, the outer box includes an upper plate, both side plates, a bottom plate connected to lower ends of both side plates, and a back plate connected to these rear ends. In particular, the bottom plate is welded or screwed to both side plates. Both ends of the bottom plate 2 are bent by 90 ° so as to be in close contact with the inner side surface of the side plate 1, and a number of weldings 3 are performed between the bending surface 2 a and the side plate 1 opposed thereto, so that the bottom plate 2 is attached to the side plate 1. Join. After the inner box is connected to the inside of the outer box connected in this manner, a heat insulating material is foamed between the outer box and the inner box, thereby forming a main body having a triple structure.

However, in the conventional outer box connecting structure, various problems are caused by connecting the bottom plate of the outer box to the side plate by welding or screws. First, since the bottom plate is joined to the side plate by a large number of weldings or screw connections, there is a problem that the number of work steps is large and the time required for manufacturing costs is long. Secondly, when foaming the heat insulating material, there is a problem that the foaming liquid leaks to the outside through between the welded portions and between the screwed portions. Third, PCM (Pre Coated
Matal) Since it is no longer possible to use an iron plate and the body must be painted separately after the connection of the body has been completed, there is a problem that the manufacturing cost increases due to the additional manufacturing process and the manufacturing time is prolonged. Was.
