LOUVER DRIVING APPARATUS FOR AIR CONDITIONER AND ITS CONTROL METHOD

PROBLEM TO BE SOLVED: To improve performance of air conditioning and contribute to energy saving by accurately sensing a distance and a horizontal position with a vertical position sensing part and a horizontal position sensing part, and controlling driving of an upper and lower louver and a horizontal louver, and further accurately discharging air which is heat-exchanged to a position where a user is existent. SOLUTION: When a user is existent on the left side viewed from the user in an air conditioned chamber from an air conditioner upon air conditioning operation, a human body sensing sensor 91 for sensing the left side with a microcomputer 10 is driven, and a vertical position sensing part 71 judges a distance between the user and an air conditioner body based upon the sensed result. A left/right louver driving part 60 is controlled such that provided the human body is existent at the right side at the center, and at the left side in response to the horizontal and distance sensed results, the left/right louver is swung into an entire horizontal region, provided it is existent only on the right side and at the center, the louver is swung from the center to the right side, and provided it is existent only on the right and left sides, it is swung to the entire horizontal region. Further, when the human body is judged the human body is existent close to the louver, and upper/lower louver driving part 50 is controlled such that the upper and lower louver is directed downward.
