    • PROBLEM TO BE SOLVED: To provide the airflow direction control method of an air conditioner, which is capable of controlling an indoor atmosphere uniformly without spoiling comfortable property. SOLUTION: The airflow up-and-down controlling vanes of an air conditioner are divided into three divisions in the horizontal direction of the same, and are constituted of a central airflow direction up-and-down control vane 19a and left-and-right airflow direction up-and-down control vanes 19b. In such an air conditioner, the angles of a plurality of airflow direction left-and-right control vanes 20 are set so that the directions of outlet airflow are directed outward while the angles of airflow up-and- down control vanes divided into three divisions, are controlled so as to be moved within 90 deg., and the angle θa of the central airflow direction up-and-down control vanes is set so as to be larger than the angle θb. Upon heating operation, the angle θa is set so as to be not smaller than 30 deg. and not larger than 80 deg. while the angle θa is set so as to be larger than the angle θb by 5 deg. or more whereby the angle of outlet air flow is widened and the arriving distance of the airflow is increased thereby heating the inside of a room uniformly to the corners of the same. Upon dehumidifying operation, the angle θa is set so as to be not less than 90 deg. while the angle θb is set so as to be not larger than 0 deg. in order to eliminate the feeling of airflow, which is given to inhabitants.
