Cyclone dust separator and a vacuum cleaner having the same

摘要

A cyclone dust separator for a vacuum cleaner, where a couple of cyclones are disposed parallel with each other and sequentially operated to separate and collect dust. The cyclone dust separator includes a bypass path guiding dust-laden air drawn in through a suction opening directly to a motor and having a first mesh that filters off dust included in drawn-in air; a first cyclone disposed at one side of the bypass path to separate the dust from the dust-laden air drawn in through the suction opening and discharge cleaned air to the motor; and a second cyclone disposed parallel with the first cyclone to separate the dust from the dust-laden air drawn in through the suction opening and discharge cleaned air to the motor. The dust included in the air is separated sequentially by the first mesh, the first cyclone and the second cyclone.
