Cyclone dust separator and a vacuum cleaner having the same

A cyclone dust separator for a vacuum cleaner, comprising:

• 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 and having a first air inlet formed alongside the first mesh to draw in the dust-laden air drawn in through the suction opening, to separate the drawn-in dust and discharge cleaned air to the motor;
• and
• a second cyclone disposed parallel with the first cyclone and having a second air inlet formed alongside the suction opening to draw in the dust-laden air drawn in through the suction opening, to separate the drawn-in dust and discharge cleaned air to the motor,
• wherein the dust included in the air is separated sequentially by the first mesh, the first cyclone and the second cyclone.

A vacuum cleaner comprising:

• a suction brush;
• a motor mounted in a main body of the vacuum cleaner to generate a suction force for drawing in dust-laden air through the suction brush;
• and
• a cyclone dust separator mounted in the main body to separate and collect dust from the dust-laden air,
• the cyclone dust separator comprising,
• 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 and having a first air inlet formed alongside the first mesh to draw in the dust-laden air drawn in through the suction opening, to separate the drawn-in dust and discharge cleaned air to the motor;
• and
• a second cyclone disposed parallel with the first cyclone and having a second air inlet formed alongside the suction opening to draw in the dust-laden air drawn in through the suction opening, to separate the drawn-in dust and discharge cleaned air to the motor,
• wherein the dust included in the air is separated sequentially by the first mesh, the first cyclone and the second cyclone.
