- As shown in FIGS. 1 and 2, a conventional cyclone-type
dust collecting apparatus 10 for a vacuum cleaner comprises acyclone body 20, adust collecting receptacle 30, and agrill assembly 40. - The

dust collecting receptacle 30 is removably connected to thecyclone body 20 and collects dusts separated from air by the cyclone stream formed by thecyclone body 20. - The
grill assembly 40 is mounted at an end of theair discharge port 24 inside thecyclone body 20 and prevents the dusts collected in the dust collecting receptacle from flowing back through theair discharge port 24. Thegrill assembly 40 comprises agrill body 41, a plurality ofpaths 42 formed on the outer circumferential surface of thegrill body 41 to fluidly communicate with theair discharge port 24, and adust blocking member 43 disposed at an end of thegrill body 41. - Such conventional cyclone-type dust collecting apparatus for a vacuum cleaner structured as above has the air inlet and
discharge pipes extension pipes air inlet pipe 21 in an oblique direction with respect to thecyclone body 20 by a suction force generated at a suction port E of the vacuum cleaner, and the drawn in air flows towards the bottom of thedust collecting receptacle 30 forming a cyclone stream. In this process, the dusts included in air are separated from air by a centrifugal force and collected in thedust collecting receptacle 30. Air flows towards the cleaner body B through thepaths 42 of thegrill assembly 40,air discharge port 24, andair discharge pipe 22 by the cyclone stream reversed at the bottom of thedust collecting receptacle 30 and rising up having a radius smaller than that of the descending cyclone stream. - The cleaned air towards the cleaner body B is discharged outside through a paper filter (not shown) provided in the cleaner body B, and thus, fine dusts which are not separated by the cyclone dust collecting apparatus is filtered by the paper filter and collected.

- However, such conventional cyclone-type dust collecting apparatus cannot prevent fine dusts smaller than the
paths 42 flowing back through thepaths 42 together with the discharged air although it can effectively separate and collect the dusts larger than thepaths 42 of the grill assembly. As a result, reversing fine dusts are collected in the paper filter provided in the cleaner body B and the amount of the dusts collected in the paper filter increases. Accordingly, the life span of the paper filter is shortened and an improvement with respect to such a problem is required. - Accordingly, it is an object of the present invention to provide a cyclone type dust collecting apparatus for a vacuum cleaner, which has a second filtering means for filtering the minute dusts in air reversing along the air path of the grill assembly, and thereby reducing the amount of dusts to be filtered at the paper filter and extending the life span of the paper filter.
