Title:
AIR SUCTION AND BLOWING DEVICE AND ELECTRIC VACUUM CLEANER COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2012/137417
Kind Code:
A1
Abstract:
The inside of a main body section (111) is the main passage for air and the inside of a blower passage section (112) disposed in the main body section (111) is an auxiliary passage for air. A power fan (114b) inside a suction chamber (115) rotates when a suction air current is formed in the main passage. A blowing fan (114a) rotates in conjunction with the rotation of the power fan (114b) so a blowing air current is formed in the auxiliary passage. Damage to the blowing fan (114a) caused by entry of foreign objects can be prevented, by covering the main body section (111) with an outer upper cover (118a) comprising an upper external air inlet (119a) and by connecting the upper external air inlet (119a) to a blowing air inlet (112a) via an upper filter (120a).
