Cyclone dust-separating unit for use in vacuum cleaner

A cyclone dust-separating unit for use in a vacuum cleaner, comprising:

• a whirling current generating unit to rotate air drawn in through a suction nozzle;
• and
• a dust collecting bin having an opened end and a closed end, the dust collecting bin being configured to collect and store dust or dirt centrifugally separated by a whirling current generated by the whirling current generating unit,
• wherein the whirling current generating unit and the dust collecting bin are formed of separate tube members,
• wherein the whirling current generating unit comprises a cyclone body having a first end having an air inlet formed thereto and a second end having an air outlet formed thereto, a spiral guide member disposed on a part of the first end of the cyclone body in the cyclone body to guide air flowed in through the air inlet in a spiral shape, an outflow pipe disposed on a part of the second end of the cyclone body in the cyclone body to extend to the outside of the cyclone body while penetrating through the air outlet, and a dust guide to connect a dust discharging opening formed in one side of the second end of the cyclone body with the opened end of the dust collecting bin and to guide dust or dirt discharged through the dust discharging opening to the opened end of the dust collecting bin.
