PURPOSE:To provide an air conditioning device, which enables to widely deflect and divide air flow with almost no change of air flow rate by a structure wherein a pivotal flow control vane with a special figure is provided at the center of a blow-off port. CONSTITUTION:When a flow control vane 18 is rotated about 60 deg. counterclockwise in the attached figure from the position of the vane at horizontal blowing-off, a stream F flows similarly in the case of horizontal blowing-off and then divided into a stream Fa flowing along the upper side of the flow control vane 18 and a stream Fb flowing along the lower side thereof. Then the upper side stream Fa is directed downwards with a stream Fc developed by a bias projection 16. On the other hand, the lower side stream Fb is promoted its adhering effect to the guide wall 15 of the lower side stream Fb by means of the effect of a projecting part 200 arranged on a bias action surface 20. Next, when the flow control vane 18 is rotated about 120 deg. clockwise from the set position of the vane at horizontal blowing-off, the stream F flows similarly as before and then divided into the stream Fa flowing along the upper side of the flow control vane 18 and the stream Fb flowing along the lower side thereof. The upper side stream Fa is directed in the direction adhering to the straight wall 17 by the action of the bias action surface 20. On the other hand, the lower side stream Fb is directed in the direction adhering to the guide wall 15 by the action of a flow dividing action surface 21 so as to continue to blow-off downwards. |
