(54) Apparatus for collecting dust and vacuum cleaner having the same


(57) An apparatus for collecting dust and vacuum cleaner having the same are disclosed, by which dust collecting performance is enhanced. The present invention includes a primary cyclone dust collecting part (212,214) performing centrifugal separation to collect the dust included in an air introduced via a first inlet (214a) provided to an outer circumference of the primary cyclone dust collecting part (212,214), an exhaust member (217) provided within the primary cyclone dust collecting part (212,214) wherein a multitude of perforated holes are provided to a lateral side of the exhaust member (217) to communicate with a first outlet (214b) of the primary cyclone dust collecting part (212,214), and a guide rib (218) provided to the primary cyclone dust collecting part (212,214) guiding the air introduced into the first inlet (214a) in a direction tangential to an inner wall of the primary cyclone dust collecting part (212,214) to prevent the air from being directly introduced into the exhaust member (217), the guide rib (218) making a prescribed angle with a tangential line at a point connected to the primary cyclone dust collecting part (212,214).
