Abstract
An air conditioner has a body casing provided with an air inlet port and an air blow-off port, a vertical wind shifting element disposed in the body casing for vertically shifting a blow-off direction of wind through the blow-off port, a horizontal wind shifting element disposed in the body casing for horizontally shifting a blow-off direction of wind through a blow-off port and a control apparatus for controlling the vertical and horizontal wind shifting elements. The control apparatus comprises a first driving circuit for driving the vertical wind shifting element, a second driving circuit for driving the horizontal wind shifting element, and a control unit for controlling operations of the first and second driving circuits. A switching circuit for switching operations of the vertical and horizontal wind shifting elements may be further provided. The first driving circuit is controlled to drive the vertical wind shifting element to blow off the wind with a predetermined time interval and the second driving circuit is controlled to drive the horizontal wind shifting element with a predetermined time interval after once fixing the vertical wind shifting element. Thereafter, the vertical wind shifting element is driven to blow out the wind in a mode different from a previous blow-off mode.
