Title: Electric vacuum cleaner
Inventor: KANBARA HIROMI
IPC: A47L9/18
Filed: 1995-05-31
Abstract: PURPOSE: To prevent infiltration of air containing moisture into a fan motor by arranging a spider turning together with a separator to isolate moisture from air and providing a plurality of grooves in the spider to generate an air flow in the centrifugal direction when performing a rotation of the separator. CONSTITUTION: When a fan motor 14 is rotated, air containing dust is introduced into a water pan by a fan within a fan case 15 and hits the surface of water. As a result, the dust is trapped by the water and the air ascends as containing the water to separate the moisture by a centrifugal force of the rotating separator 4. The air alone passes through a slit 5 to be introduced into the fan case 15. The infiltration of the air containing the moisture into the fan case 15 from a gap between the surface side 8 of the fan case and the fan case 15 is blocked by an air flow in the centrifugal direction as generated with the action of a plurality of spiral grooves 18 formed on the surface side 8 of the fan case of the spider 7.
