Abstract (en)
[origin: EP0067884A1] A flow direction control device (11) for controlling the direction of the air flow from a cross flow fan (12). Roughly circular arc-shaped control blades (27) are disposed with the cross flow fan, the low pressure vortex of the fan is restricted within the control blades, and the direction of the air flow can be controlled over a wide angle around the entire periphery of the fan with a compact construction in accordance with the rotation of the control blades (27). Also, with respect to the external region of the fan divided into two regions by partition members (46), (47), conversion between the normal and reverse flow directions can be achieved based upon this principle by rotating the control blades (27).
