PURPOSE:To improve the blasting and air flow deflecting characteristics of the blast device by a method wherein in the case of an air conditioning cross-flow fan attached with an air flow deflecting means, a stream of air generated by the fan is guided by a rear guider whose leeward side is enlarged gradually, and is deflected by a rotatable air flow control member of a specific configuration. CONSTITUTION:The leeward side of the rear guider 3 is enlarged gradually toward the leeward side of the air stream and the air flow control member 5 rotatable eccentrically within a predetermined range is provided on the leeward side of the stream of air in opposite relationship with the cross-flow fan 2. One end 5a of the control member 5 is semicircular in configuration and the distance between the end 5a and the fan 2 changes as the member 5 rotates eccentrically. Further, the leeward end 5b of the control member 5 is made to have a configuration such that a biasing effect is generated between the end 5b and the rear guider 3 when the end 5b comes to the position facing the fan 2, while the stream of air flows down below the horizontal direction as the member 5 rotates and is deflected downward when the end 5b comes to the position facing the fan 2. Thus, it is possible to improve the blasting and air flow deflecting characteristics of the blast device. |
