Abstract
A cyclone vacuum cleaner including a plurality of cyclone chambers arranged in a group. The cyclone chambers are configured such that frequency characteristics of noises generated from respective cyclone chambers are different from each other.
Claims18
A vacuum cleaner comprising:
- a plurality of cyclone chambers arranged in a group;
- wherein the configurations of the cyclone chambers are different from each other so that frequency characteristics of noises generated from respective cyclone chambers are different from each other.
A vacuum cleaner comprising:
- a first cyclone chamber separating large foreign matter from air;
- and
- a plurality of second cyclone chambers smaller than the first cyclone chamber and separating fine dust from the air passed through the first cyclone chamber, wherein configurations of the second cyclone chambers are different from each other so as to allow frequency characteristics of noises generated from the second cyclone chambers to be different from each other.
The vacuum cleaner as set forth in 14, wherein the second cyclone chambers further comprise extending pipes extended from portions of the second cyclone chambers with maximal diameter, and said extending pipes have lengths different from each other.
