1. A multi-cyclone dust separator, comprising:
- a first cyclone unit that centrifugally separates dust from a dust-laden air stream drawn into the first cyclone unit through a first air inlet;
a second cyclone unit that is formed inside the first cyclone unit, wherein the second cyclone unit comprises;
a second cyclone body that comprises a second air inlet through which the dust-laden air stream enters the second cyclone body,a guide unit that imparts rotation to the dust-laden air stream upon entry of the dust-laden air stream into the second cyclone unit,an air discharge hole that is formed on a bottom surface of the second cyclone body, andan air discharge pipe that is fixed to the second cyclone body and is connected to the air discharge hole; and
a dust blocking unit that prevents the dust separated by the first cyclone unit from entering the second cyclone unit through the second air inlet.

16. A multi-cyclone dust separator, comprising:
-
a first cyclone unit that centrifugally separates dust from a dust-laden air stream drawn into the first cyclone unit through a first air inlet; a second cyclone unit that is formed inside the first cyclone unit; and a third cyclone unit that is formed inside the second cyclone unit, wherein the second cyclone unit comprises; a second cyclone body that comprises a second air inlet through which the dust-laden air stream enters the second cyclone body; and a first guide unit that imparts rotation to the dust-laden air stream upon entry of the dust-laden air stream into the second cyclone unit, and wherein the third cyclone unit comprises; a third cyclone body that comprises a third air inlet through which the dust-laden air stream, from which the dust has been separated by the second cyclone unit, enters the third cyclone body; and a second guide unit that imparts rotation to the dust-laden air stream upon entry of the dust-laden air stream into the third cyclone unit, wherein the second cyclone unit is fixed to a core of the first cyclone unit, and the third cyclone unit is fixed to a core of the second cyclone unit, and wherein the third cyclone unit comprises; a third cyclone body that is fixed to an internal surface of the second cyclone unit using at least one first fixing rib; an air discharge hole that is formed on a bottom surface of the third cyclone body; and an air discharge pipe that is fixed to an internal surface of the third cyclone body using at least one second fixing rib and is connected to the air discharge hole. - View Dependent Claims (17, 18, 19, 20)
