Referring to FIG. 1, a panel 100 used in an electric home appliance is fabricated by bending one side and the other side of a steel sheet.
The one side and the other side are arranged adjacent to each other in the bending process and then a corner 100 is formed.
In this instance, it is impossible to couple the two sides completely in the bending process and a slit or a hole (hereinafter, a gap region) is usually formed.
The gap region 110 happens to expose a sharp surface of the steel sheet and deteriorates safety. Also, the gap region 110 generates tolerance or more errors and it is then difficult to assemble components.
Accordingly, a welding process is additionally performed to finish the gap region 110 in the prior art to which the present disclosure pertains to. However, such a welding process is likely to raise production cost and the welded portion has to be polished additionally.
Recently, an insert assembly developed including a wedge 200 and a supporter 300 which are assembled to each other as shown in FIG. 5 and the insert assembly is inserted in the gap region 110.
However, such an insert assembly has to use many components and requires auxiliary assembly lines. The conventional insert assembly has disadvantages of much production time and high production cost.
