BLOWER OF VACUUM CLEANER |
摘要 |
Disclosed herein is an air-blowing apparatus of a cleaner. The air-blowing apparatus comprises a fan having a plurality of blades spaced apart from each other in the circumferential direction of the fan for generating a blowing force in the centrifugal direction thereof, and a diffuser disposed outside the fan in the radial direction of the fan for diffusing air blown from the fan. Each blade is formed such that at least a part of the blade is shorter than the other part of the blade extending to the outer diameter of the fan, whereby noise is reduced while blowing efficiency is not affected. |
