DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction control device for an air conditioner, which enhances comfort by sending evenly comfortable airflow to a plurality of occupants in an air-conditioned room.

[0002]

2. Description of the Related Art A conventional wind direction control device for an air conditioner of this type is disclosed in Japanese Patent Application Laid-Open No. 1-127840. The wind direction control device of this air conditioner, particularly during heating, is based on a signal from a human body detection sensor,
It is determined which zone in the room there is a person, and if the temperature of the blown wind detected by the blowout temperature sensor is less than a predetermined reference value, the wind direction control device determines the zone where the person is determined to be. The control means controls the blowout air from the indoor unit to not go.If the blowout temperature is equal to or higher than the reference value, the wind direction control device controls the blowout wind to go to the zone where the control means determines that there is a person. By doing so, the cold air does not directly hit the user in any zone, and the warm air is directly applied to the occupant regardless of the zone in which the person is, so that the feeling of heating is effectively obtained.
