<P>PROBLEM TO BE SOLVED: To collect dust to be caught which is separated by a swirl air flow, into a dust collecting container. <P>SOLUTION: A cyclone separator is provided with an inner cylinder formed with an exhaust hole for swirling air sucked from a circumferential air flow inlet provided in a circumferential part of a dust collecting container, along the inner circumferential surface of substantially cylindrical shape, and exhausting the air from the center of the dust collecting container, and relatively large dust contained in the air is caught at the bottom part of the dust collecting container. The bottom part of the dust collecting container has a bottom lid provided to be opened and closed, and the bottom lid is provided with a fitting portion for fitting to the lower part of an inner cylinder. Accordingly, the air is prevented from flowing in the dust collecting container having dust collected and the bottom part of the inner cylinder, the dust is collected in the dust collecting container, and at the same time, dust collected at the bottom part of the dust collecting container having the bottom lid opened, is readily disposed of. <P>COPYRIGHT: (C)2012,JPO&INPIT |
