The apparatus comprises: a door traction unit arranged facing against the door, moving front and back, and possibly fastened with an oven door; and a control unit installed in the door traction unit and whose one end toward the door is protruding in the front direction of the door traction unit. The control unit detects the position of the door traction unit, and controls the movement of the door traction unit. According to embodiments of the present invention, the position of the door traction unit is detected by installing the control unit in the door traction unit, thereby controlling the movement of the door traction unit. Hence, over progress of the door traction unit toward the door is prevented, and stress on the door is minimized.</p> |
