Apparatus for operating auto-shutter in air-conditioner
First Claim
1. An auto-shutter operating apparatus for use in an air-conditioner having an external casing including a first side having an air exit opening therein, the auto-shutter operating apparatus comprising:
- a louver frame, having an exit opening therein, mounted in said casing with the exit opening of the casing and louver frame in alignment;
an auto shutter movably mounted in said frame for movement between an opened position opening the exit opening of the louver frame and a closed position closing the exit opening of the louver frame; and
shutter driving means for driving the auto-shutter between said open and closed positions,said shutter driving means comprises;
a drive motor having a housing and means for rotatably mounting said housing to allow the motor to tilt forwardly and backwardly relative to said first side;
a rotational rod having a screw thread formed along its outer surface and being coupled to said driving motor for rotation along its longitudinal axis by said motor;
a bushing coupled with said rotational rod for reciprocal movement therealong in response to the rod being rotated by said motor in either a first or second rotational direction;
a slider having a first end pivotally coupled with the auto-shutter and a second end coupled to said bushing;
a rotational rod guider mounted in said frame which guides and supports rotation of the rotational rod;
guide rails formed on opposed surfaces of said louver frame adjacent said exit opening therein; and
means on said auto-shutter engaged with said guide rails for guiding movements of the auto-shutter, said guide rails having a predetermined shape defining a path of travel for the auto-shutter to cause said motor and rotational rod to tilt toward and away from said first side as said auto-shutter approaches and leaves said closed position thereof.

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.
