Abstract
A cyclone dust collecting apparatus has: a cyclone body; a suction pipe extended to be protruded into the cyclone body by penetrating one side of the cyclone body in order to guide an air, which has been drawn into through a suction unit, into the cyclone body; a discharge pipe for guiding a clean air centrifugally separated in the cyclone body to an outside of the cyclone body; and a guide member for guiding the air, which whirls along a side wall of the cyclone body after being drawn into through the suction pipe, to a lower side of the suction pipe. According to the cyclone dust collecting apparatus of the present invention, a deterioration of suction force of the cyclone dust collecting apparatus is prevented, and thus a dust collection efficiency of the cyclone dust collecting apparatus will be improved.
