Title:
DOUBLE SUCTION TYPE BLOWER
Document Type and Number:
Japanese Patent JP3675132
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To make the securing of a strength required for holding a motor and the reduction of blowing noise consistent with each other in a double suction type blower which sucks air on the axially opposite sides, for blowing the air.
SOLUTION: A ring-like attaching stay part 14b for a fan drive motor is formed therein with a reinforcing rib 14f having a protrusion and recess shape in a surface on the side remote from a stream C of air flowing through a gap part 14d, and the outer surface 14g facing the air stream C is formed in an arcuate cross-sectional shape along the air stream C. With this reinforcing rib 14f, it is possible to ensure a required strength for the attaching stay part 15b, and as well to allow the air to smoothly flow around the attaching stay part 14b without disturbing the stream air due to the arcuate cross-sectional shape of the outer surface 14g of the attaching stay part 14b on the side where the air flows, thereby it is possible to reduce the noise.
