<p>PROBLEM TO BE SOLVED: To prevent enlargement even if a plurality of opposed plates and first dust collecting electrodes are built in an air conditioning apparatus by uniting a plurality of the opposed plates arranged approximately parallel to the air flow direction in an ionization part and the first dust collecting electrodes arranged approximately rectangularly to the air flow and positioned on the upstream side in the dust collecting part in the air flow direction. SOLUTION: An ionization part 100 is provided with a plurality of opposed plates 16 arranged approximately parallel to the air flow direction and an electric discharge wire 17 installed between mutually paired opposed plates 16. A dust collecting part 200 is provided with first dust collecting electrodes 10a arranged at right angles to the air flow and positioned on the upstream side in the air flow direction, second dust collecting electrodes 10b arranged at right angles to the air flow and positioned on the downstream side in the air flow direction, and a filter member 8 installed between both dust collecting electrodes 10a, 10b. Caulking parts 26 to fix the first dust collecting electrodes 10a are formed in opposed electrodes 6 and the ionization part 100 and the dust collecting part 200 are united by fixing the first dust collecting electrodes 10a by the caulking parts 26.</p> |
