Abstract
A grill assembly of a cyclone dust-collecting apparatus for a vacuum cleaner may improve the capability of dust-collecting of the vacuum cleaner by reducing the amount of the filth drawn into a vacuum-generating device of the vacuum cleaner through a grill. The grill assembly may be disposed at an inlet of an air-discharging passage of a cyclone body that separates filth from a whirling air current by centrifugal force. The whirling air current may prevent the filth from being drawn into the vacuum-generating device of the vacuum cleaner. The grill assembly may include a grill body and a plurality of passages disposed therein. An extended line of the centerline of the passages may form an acute angle with a streamline of the whirling air current.
