GRILL ASSEMBLY FOR A CYCLONE DUST COLLECTING APPARATUS FOR AVACUUM CLEANER

摘要

A grill assembly for a cyclone dust collecting apparatus for a vacuum cleaner capable of improving the capability of dust collection of the vacuum cleaner by reducing the amount of the filth drawn into a filter protecting the vacuum-generating. The grill assembly is disposed at an upper part of an air discharging passage of the cyclone body that generates a whirling air current within the air drawn thereinto and separates filth from the whirling air by the centrifugal forces developed in the whirling air current. The grill assembly comprises a grill body, and a plurality of blades formed at a predetermined separation providing a passage along an outer circumference of the grill body. The passage is at an acute angle with the flow direction of the whirling air current, and each blade includes a protrusion member protruding outwardly from the outer circumference of the grill body.
