PURPOSE:To provide an air direction adjusting device for an air conditioner capable of stabilizing an air direction, extending an air reaching distance and increasing substantially a variation width of the air direction by a method wherein a sectional shape of an air direction adjusting vane is of a triangular shape. CONSTITUTION:An air direction adjusting vane 2 is gradually widened from its upstream side and has a wind stream line of triangular shape with a curvature and a sectional shape converged at a curvature of a half of the widened sectional width near a blowing port. This vane is rotated around the center of the converging curvature. A major flow 3 of blowing air is gradually changed in its direction along the upstream side of the vane and finally varied up to a angle which is approximately horizontal. A sub-flow of air 4 is flowed along the downstream surface of the air direction adjusting vane 2 and finally absorbed into the major flow 3. In this way, the major flow and sub-flow are made integral or merged together to make a stable air direction and at the same time the damping rate of air speed is reduced and an air reaching distance is extended. The air direction adjusting vane is operated such that the major stream 4'' is blown downwardly in a direction of 60 deg. at a downward blowing position 2'' and an air variation width is a large value of 60 deg. in respect to a rotational angle of 25 deg.. |
