IMPELLER FOR CROSS FLOW BLOWER

PURPOSE: To improve efficiency and to reduce noise by suppressing an acceleration rate as small as possible at passing time between blades, and decreasing a dynamic friction loss. CONSTITUTION: Relating to an impeller for a cross flow blower, it has a partitioning plate arranged with a prescribed space in a blower axial direction and a blade 1 positioned between these partitioning plates to direct a lengthwise direction in the blower axial direction also to be arranged in a peripheral direction with a prescribed space apart in the vicinity of a peripheral end of the partitioning plate. Accordingly, the blade 1 is formed in a blade shape where its maximum warped position agrees with the center of a blade chord, also a thickness (2Ya ) of the maximum warped position of the blade 1 and a length (t) of a circular arc, connecting between middle points of a circular arc-shaped neutral line of the blades 1 adjacent to each other by the circular are with a blower axis serving as the center, satisfy a relation where 0.1178
