CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit under 35 U.S.C. � 119 (a) of Korean Patent Application No. 2005-50897 filed on Jun. 14, 2005, the entire content of which is incorporated herein by reference.
SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a highly durable cyclone dust collecting device, which uses a corona discharge to improve separation efficiency of fine contaminants.
BRIEF DESCRIPTION OF THE DRAWINGS The above and other aspects, features and advantages of the present invention will become more apparent and more readily appreciated from the following detailed description of the embodiment taken with reference to the accompanying drawings of which:
DETAILED DESCRIPTION OF THE INVENTION Exemplary embodiments of the present invention will be described in detail with reference to the annexed drawings. In the drawings, the same elements are denoted by the same reference numerals throughout. In the following description, detailed descriptions of known functions and configurations incorporated herein have been omitted for conciseness and clarity.
The first and the second fine contaminant collection parts 510, 520 are formed in a grounded condition on inner surfaces of the first and the second cyclone chambers 310, 350. The third and the fourth fine contaminant collection parts 530, 540 are formed in a grounded condition on inner surfaces of the connection paths 380 and the cover part 230. Accordingly, after being ionized by the discharge needle 410, fine contaminants D are collected by the first and the third fine contaminant collection parts 510, 530 while flowing toward the second cyclone chambers 350. The fine contaminants D that are not collected by the first and the third fine contaminant collection parts 510, 530 flow into the second cyclone chambers 350, are re-ionized by the discharge electrode part 420 and then collected by the second and the fourth fine contaminant collection parts 520, 540. The fine contaminant collection parts 510, 520, 530, 540 can collect the fine contaminants D by using the electromagnetic force only if the fine contaminant collection parts are made of conductive material and rightly grounded. The fine contaminant collection parts 510, 520, 530, 540 according to the present embodiment are formed by spraying a conductive paint over the first cyclone chamber 310, the second cyclone chambers 350, the intermediate cover 240 forming the connection paths 380, and the cover part 230 forming the discharge path 390. Therefore, the fine contaminant collection parts 510, 520, 530, 540 do not require the cyclone dust collecting device 200 to have a complicated structure. However, a member of conductive material may be separately formed.
