Abstract
This invention relates to a suction inlet/discharge outlet opening or closing apparatus for an air conditioner having a function to close a suction inlet and a discharge outlet at the time of recovery of electric power, with reference to a time duration retrieved from an appropriate storage containing the time duration counted during a closing/opening of the suction inlet and discharge outlet, and a method therefor. The apparatus includes a voltage sensing unit for detecting input voltage varied during an opening or closing of the suction inlet and discharge outlet, a control unit for determining whether or not power failure occurs and, based upon the input voltage sensed by the voltage sensing unit, for controlling the opening or closing of the discharge outlet door and suction grille, a memory unit for memorizing the time interval for an opening or closing of the discharge outlet door and suction grille before the power failure occurs, and a driving unit adapted to move the discharge outlet door and suction grille only for the time interval stored in the memory means such that the discharge outlet and suction inlet are fully closed.
