<P>PROBLEM TO BE SOLVED: To provide a cyclone dust collecting device securing visibility of a dust collecting case. <P>SOLUTION: The vacuum cleaner includes a dust collecting case 3 formed of a swirl chamber 1 for swirling dust-containing air sucked by an electric fan and separating dust from the air, and a dust collecting chamber 2 for collecting the dust from the swirl chamber 1, and rubber-like transparent elastic sheet members 15 and 16 are stuck to the inside surface of the dust collecting case 3. The dust-containing air flows into the swirl chamber 1 by a suction force generated by the electric fan, the dust and air are separated from each other by a centrifugal force caused by a swirl flow, the separated dust is collected in the dust collecting chamber 2, and only air is discharged from the dust collecting case 3. The dust collides with and is rubbed against the dust collecting case, the elastic sheet members 15 and 16 are elastically concaved largely, scatter collision pressure of the dust, and are restored, so that the elastic sheet members 15 and 16 are not scratched, and secure the visibility of the dust collecting case 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
