Therefore, the stopper 256 and the stopper hole 255 may be referred to as support means for maintaining the cover in a rotated state. In addition, the stopper 256 and the stopper hole 255 may be formed to be opposite to the illustrated embodiment. That is, the stopper 256 may be provided in the cover 252, and the stopper hole 255 may be provided in the case 251.

In addition, the hook 257 protrudes from the lower end of the case 251, that is, the end where the wire guide 253 is formed. The hook hook 257 is formed at an end portion opposite to an end portion at which the hinge 254 is formed. In addition, a locking end 258 is formed at an end of the cover 252 corresponding to the locking hook 257. In other words, the locking end 258 is formed at the point where the locking hook 257 is positioned while the cover 252 is closed. Therefore, when the cover 252 is closed, the locking hook 257 is caught by the locking end 258 to maintain the cover 252 in close contact with the case 251.

As shown in FIG. 4, when the service man grabs and lifts the lower end of the cover 252, that is, the end at which the locking end 258 is formed, the locking hook 257 is connected to the locking end 258. Is separated from. At this time, the hook hook 257 is formed to have a slight elastic force, it can be bent by the lifting force to lift the cover 252 to be returned to its original position.

In a state where the locking end 258 is separated from the locking hook 257, the stopper 256 is rotated until the stopper 256 is inserted into the stopper hole 255. When the stopper 256 is inserted into the stopper hole 255, the stopper 256 is rotated as shown in FIG. 4 even when the cover 252 is removed.

In this state, the service man can repair the electric parts inside the case 251 using both hands. When the repair is completed, the cover 252 is lowered so that the hook 257 is caught by the hook 258 to close the opening of the case 251. Here, if the hand is released while the cover 252 is lowered only to the extent that the stopper 256 can be removed from the stopper hole 255, a rotation moment is generated by the weight of the cover 258. Then, the cover 252 is rotated so that the locking hook 257 is caught by the locking end 258.

As described above, a means is provided so that the cover 252 of the control box assembly 25 is rotatably connected to the case 251, and the cover 252 is fixed while being rotated, thereby providing a control box assembly ( 25) there is an advantage that the process of repairing can be made easily.
