[Effect of idea]

As mentioned above, the present invention is based on a control panel in which an operation display unit is placed on the back side of the door and a square window hole facing the front side is bored, and the opening of the door corresponds to the long side of the window hole. Bend the ends almost the entire length toward the back side to form each mounting piece, and attach both ends of both mounting pieces in the long direction above and below the edge of the opening end of the door corresponding to the short side direction of the window hole. The mounting plates are attached to each other so that they are in contact with each other, and the display panel on which the operation buttons and meters of the operation display unit are installed is installed on both mounting pieces, so it corresponds to the long side of the window hole. By bending the opening end, the appearance of the gap and welding dents between the opening end and the angle, which is conventional, is improved, and the mounting piece is formed. However, since the door itself is bent, it is easy to process, and has the advantage that the door itself is reinforced by bending.
Furthermore, since the display panel is installed on both mounting pieces, the display panel can be easily mounted. In addition, by attaching the mounting plates with the long side ends of both mounting pieces touching the upper and lower edges of the opening edge of the door corresponding to the short side direction of the window hole, the short side of the window hole can be shortened. The mounting plate attached to the upper and lower opening edge edges in the side direction can be easily positioned, so the mounting plate can be attached without requiring sufficient positioning, processing is simple, and the mounting piece can be folded. By using a door with a thickness that can be curved, the thickness of the mounting plate can be increased to a certain extent to strengthen the door and increase its strength.Moreover, the thickness of the mounting plate is not restricted, so it can be adjusted as appropriate. By using a thicker plate, the strength of the entire door can be increased by the mounting pieces in the long side direction and the mounting plate in the short side direction.
