GRILLE ASSEMBLY BODY OF CYCLONE DUST COLLECTOR FOR VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a grille assembly body of a cyclone dust collector for a vacuum cleaner, which can enhance dust collection performance of the vacuum cleaner. SOLUTION: This grille assembly is disposed upstream of an air discharge passage of a cyclone body, which makes intake air form a turning air flow so as to make dirt separated from the turning air flow by a centrifugal force, and prevents the dirt from flowing into the side of a vacuum generator of the vacuum cleaner. The grille assembly comprises a grille body 110 and a plurality of channels formed in the grille body 110, and the channel is formed in such a manner that an extension line of a center line thereof makes an acute angle with a stream line of the turning air flow.
