Cyclone dust collector and vacuum cleaner therewith
First Claim
1. A cyclone dust collector comprising:
- a cyclone body shaped to have an upper portion and a lower portion, said upper portion being wider than the lower portion, said cyclone body also having a suction port and a discharge port,a dust receptacle connected to the cyclone body near the lower portion;
a grill member within the cyclone body, said grill member being located in the cyclone body and filtering particles from air in the cyclone body before it exits the discharge port;
and a blocking member within the cyclone body for partially blocking the grill member;
wherein the blocking member is disposed to face an inner circumference of the cyclone dust collector, the inner circumference being adjacent to the suction port.

Abstract
A cyclone dust collector and a vacuum cleaner having the same. The cyclone dust collector has a cyclone body shaped to have a relatively wider upper portion and a relatively narrower lower portion and also has a suction port and a discharge port, a grill member connected to the discharge port, a dust receptacle connected to the cyclone body, and a blocking member for partially blocking the grill member. Air drawn in through the suction port moves in an increasingly wider radial path as it travels upwardly to the discharge port, increasing the centrifugal force on suspended particles as they travel toward the discharge port. The shape of the cyclone body prevents turbulent flow from being generated. Dust is prevented by the blocking member from attaching to the grill member before being centrifuged, performance of the grill member is enhanced.
