Document Type and Number:
WIPO Patent Application WO/2007/018075
Kind Code:
A1
Abstract:
A cross-flow fan made of a resin enabling the elimination of an annealing step
and a reduction in the quantity of disks and having excellent fan strength and
air blowing performance and a method of manufacturing the cross-flow fan. The
cross-flow fan (1) comprises a plurality of blades (2) and a plurality of plates
(3, 4, 5). The plurality of blades (2) are disposed annularly around the rotating
axis of the cross-flow fan. The plurality of plates (3, 4, 5) comprise insertion
parts (33, 43, 53) formed of holes or grooves into which the blades (2) are inserted
and projected parts (34, 44, 54) projected from the peripheral edge parts of the
insertion parts (33, 43, 53) in the direction of the rotating axis, and are disposed
at intervals in the direction of the rotating axis. Then, the blades (2) are fixed
