ABSTRACT:
An apparatus for operating an auto-shutter in an air-conditioner having an external casing includes a louver frame having an air exit installed in the external casing, an auto-shutter movable between an opened position opening the exit and a closed position closing the exit, and a shutter driver driving the auto-shutter. The shutter driver includes a driving motor which is rotatably mounted in the casing for tilting forwardly and backwardly, a screw-rod rotationally coupled with the driving motor, a bushing coupled with the rotational rod which ascends and descends along with the rotational rod when rotated, a slider, one end of which is coupled with the auto-shutter and the other end of which is coupled with the bushing. The frame and shutter include cooperating surfaces defining to guide the auto-shutter and cause the driving motor and the rotational rod to tilt by a predetermined angle as the auto-shutter moves from the opened position to the closed position.
