Grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner
First Claim
1. A vacuum cleaner comprising a vacuum-generating device, a cyclone dust collecting apparatus, a grill assembly for the cyclone dust collecting apparatus, the grill assembly being disposed at an upper part of an air discharging passage of a cyclone body that generates whirling air current from the air drawn thereinto and separates filth from the drawn air by a centrifugal force of the whirling air current, the grill assembly preventing the filth from being drawn into a vacuum-generating device of the vacuum cleaner, and comprising:
- a grill body; and
a plurality of blades disposed along an outer circumference of the grill body and being formed so that adjacent blades are spaced and separated by a predetermined space thereby defining a passage between each two adjacent blades, the passage formed at an acute angle with respect to a stream line of the whirling air current, each blade including a protrusion member protruding from the outer circumference of the grill body in a radially outward direction.

Abstract
A grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner capable of improving the capability of dust collecting of the vacuum cleaner by reducing the amount of the filth drawn into a vacuum-generating device through a grill. The grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner is disposed at an upper part of an air discharging passage of a cyclone body that generates whirling air current from the air drawn thereinto and separates filth from the drawn air by a centrifugal force of the whirling air current. The grill assembly for preventing the filth from being drawn into a vacuum-generating device of the vacuum cleaner comprises a grill body, and a plurality of blades formed at a predetermined space for forming a passage along an outer circumference of the grill body. The passage is at an acute angle with a stream-line of the whirling air current, and each blade includes a protrusion member protruding from the outer circumference of the grill body to the outer part.
