<p>PROBLEM TO BE SOLVED: To provide an air cleaner which enhances collection efficiency without using filter. SOLUTION: An outside air introducing port 2 and a blow-off port 3 are formed on a main body case 1. A conically cylindrical outer cylinder 4 of which the lower side becomes a smaller diameter is disposed on the inner part of the main body case 1. An inner cylinder 6 is disposed on the upper part of inner side of the outer cylinder 4. A cyclone part S is constituted by disposing a motor 7 and a suction fan 8 respectively on the upper side of the inner cylinder 6. A dust box 5 is arranged on the lower side of the outer cylinder 4. In this air cleaner, dust in the sucked outside air is separated in the cyclone part S and is collected into the dust box 5. Therein, further, a means 10 collecting the dust in the sucked outside air by electrically aggregating and attaching the same is disposed.</p> |
