[0034] The cyclone dust collecting apparatus for use in the upright type vacuum cleaner includes a cyclone body comprising an air intake pipe connected to the air intake path, and an air discharge pipe connected to the air discharge path, the cyclone body includes provisions to produce a whirling air current from dust-laden air is drawn through the air intake pipe, a dust receptacle removably connected to the cyclone body, for collecting dust separated from the dust-laden air whirling inside of the cyclone body by centrifugal force, and a grill assembly arranged at an entrance of the air discharge pipe inside of the cyclone body, for preventing the dust separated from the dust-laden air from escaping through the air discharge pipe. The grill assembly includes a grill body formed as a hollow cylinder with open upper end, a plurality of air passages formed on an outer surface of the grill body that permit fluid to flow from outside the grill assembly to the air discharge pipe, and a dust blocking member arranged at a lower portion of the second grill body, for blocking the dust entrained in an air ascending toward the grill body so as to deflect the dust toward the whirling air current, the dust blocking member comprising a first member formed as a frustum-cone having a gradually increasing diameter downward, and a second member vertically extending down from the first member, the second member having a predetermined length.
Problems solved by technology
As the dust escapes, the amount of dust collected by the paper filter increases, or when there is no paper filter, there is an increased amount of dust discharged out of the dust collecting apparatus.
As a result, the dust collecting efficiency is degraded.
However, conventional dust blocking members 43, 430 are limited in their ability to prevent all of the dust from escaping.

A grill assembly of a cyclone dust collecting apparatus for use in a vacuum cleaner is disclosed. The grill assembly includes provisions that help to block dust ascending towards the grill body and deflect that dust towards a whirling air current. The grill assembly has a blocking member that can include a first member formed as a frustum-cone and a second member formed as a hollow cylinder.
Description
[0001] 1. Field of the Invention[0002] The present invention generally relates to a cyclone dust collecting apparatus for use in a vacuum cleaner, and more particularly, it relates to a grill assembly having improved structure capable of separating dust and foreign substances (hereinafter called "dust") from an air moving inside of the cyclone dust collecting apparatus, and a cyclone dust collecting apparatus having the grill assembly.[0003] 2. Description of the Prior Art[0004] A cyclone dust collecting apparatus separates particles from a fluid using a centrifugal force, and has been widely used in the industrial fields due to its high resistance to temperature and pressure. Such a cyclone dust collecting apparatus is also used in vacuum cleaners.[0005] A representative exemplary of such a cyclone dust collecting apparatus is shown in Korean Patent No. 317117 issued to the same applicant, and FIG. 1 schematically shows a sectional view of such cyclone dust collecting apparatus for...
