A cyclone dust collecting apparatus for a vacuum cleaner is disclosed. The cyclone dust collecting apparatus comprises a cylindrical cyclone body secured to a top of a dust collecting chamber which is provided in a cleaner body and connected to an air drawing path and an air discharging path, the cylindrical cyclone body having an air inlet and an air outlet corresponding to the air drawing path and the air discharging path, respectively, a dirt collecting container removably disposed at a lower portion of the cyclone body for collecting dirt and contaminants centrifuged at the cyclone body, a partition plate disposed between the cyclone body and the dirt collecting container, a first dirt path protruded outwardly from a side of a bottom of the cyclone body for discharging the dust and contaminants centrifuged at the cyclone body into the dirt-collecting container, and a second dirt path protruded outwardly from a side of a top of the dirt collecting container for discharging the dust and contaminants centrifuged at the cyclone body into the dirt collecting container, the first and the second dirt paths corresponding to each other.

1. A cyclone dust collecting apparatus for a vacuum cleaner comprising: a cylindrical cyclone body secured to a top of a dust collecting chamber which is provided in a cleaner body and connected to an air drawing path and an air discharging path, the cylindrical cyclone body having an air inlet and an air outlet corresponding to the air drawing path and the air discharging path, respectively; a dirt collecting container removably disposed at a lower portion of the cyclone body for collecting dirt and contaminants centrifuged at the cyclone body; a partition plate having an opening disposed between the cyclone body and the dirt collecting container; a first dirt path protruded outwardly from a side of a bottom of the cyclone body for discharging the dust and contaminants centrifuged at the cyclone body into the dirt-collecting container; and a second dirt path protruded outwardly from a side of a top of the dirt collecting container for discharging the dust and contaminants centrifuged at the cyclone body into the dirt collecting container, the first and the second dirt paths coupled to each other through the opening in the partition plate. 2. The cyclone dust collecting apparatus of claim 1, wherein the partition plate is connected to an opened bottom of the cyclone body, and has a dirt passage hole disposed at a position corresponding to the first and the second dirt paths. 3. The cyclone dust collecting apparatus of claim 1, wherein the first and the second dirt paths protrude outwardly from the cyclone body and the dirt collecting container, respectively, in a tangential direction with respect to outer surfaces of the cyclone body and the dirt collecting container. 4. The cyclone dust collecting apparatus of claim 1, wherein the second dirt path formed on the dirt collecting container has the larger curvature radius than that of the first dirt path formed on the cyclone body. 5. The cyclone dust collecting apparatus of claim 1, further comprising dirt rotation preventing means for preventing the dust and contaminants flowing into the dirt collecting container from rotating. 6. The cyclone dust collecting apparatus of claim 5, wherein the dirt rotation preventing means comprises at least one dividing piece protruded from an inner circumference of the dirt collecting container. 7. The cyclone dust collecting apparatus of claim 6, wherein the dividing piece extends obliquely from the top of the dirt collecting container to the bottom thereof. 8. The cyclone dust collecting apparatus of claim 1, wherein the cyclone body comprises: a centrifuging container having a shape of a cylinder, of which both ends are opened; and a head having an air drawing pipe connected to the air drawing path for guiding the air to flow obliquely with respect to the centrifuging container, and an air discharging pipe of which one end is connected to a grill protruded toward the opened bottom of the centrifuging container and the other end is connected to the air discharging path, the head being connected to an opened top of the centrifuging container.
