PURPOSE:To enable the change in blow-off flow by shifting eddy of a cross flow fan by means of rotating a part of the down stream of rear guider. Also to enable a drastic deviation of the flow by equipping a guide wall to which the flow is adhered downstream of the guider. CONSTITUTION:Rear guider 9 comprised up stream side material 9a, and downstream side material 9b which rotates around shaft 10. The rotation angle Q of the guider rapidly begins to increase its deviation angle alpha when it is 45 deg. or larger. The deviation angle, about twice that of the rotation angle Q is obtained. Because with a bit turn of a lever (not shown), twice as large deviation angle is obtained, good operation can be attained. Also, by adding a guide wall 16 as shown in the figure, the better operation and control can be attained by the use of flow adhesion effect. |
