Grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner
First Claim
1. A grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner, 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 whirling air by a centrifugal force, the grill assembly preventing the filth from drawing into a vacuum generating device of the vacuum cleaner, and comprising:
- a grill body having an upper part and a lower parts that include a plurality of passages therein and a lower opening;
an extension pipe having an upper end, a lower end, and a diameter which is substantially the same as that of the air discharging passage, and the lower end of the extension pipe being positioned between the upper part and the lower part of the grill body; and
a shielding member shielding the lower opening of the grill body.

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, disposed at the upper part of the air discharging passage of a cyclone body that separates filth from a whirling air current by a centrifugal force for the whirling air current of the drawn air for preventing the filth from being drawn into the vacuum generating device of the vacuum cleaner, includes a grill body and a plurality of passages disposed therein. The extended line of the center line of the passages forms an acute angle with a stream line of the whirling air current.
