<P>PROBLEM TO BE SOLVED: To provide an air cleaning apparatus capable of stably cleaning air without generating abnormal discharge by protecting a dielectric covering the metallic conductor of a high voltage electrode from thermal stress and preventing damage. <P>SOLUTION: The air cleaning apparatus uses the discharge electrode having the high voltage electrode 2 wherein a space 2g is provided in a tube of the tubular dielectric 2b for inserting the metallic conductor 2a, and a conductor 2e electrically connecting the metallic conductor 2a to the tubular dielectric 2b, and a grounding electrode 3 with a conductor 3t connected to an adsorbent 3h adsorbing chemical substances. The space 2g between the metallic conductor 2a and tubular dielectric 2b prevents damage of the tubular dielectric body 2b by thermal stress at a discharge time. The connection of the metallic conductor 2a to the tubular dielectric 2b by the conductor 2e stabilizes the discharge and causes little abnormal discharge. <P>COPYRIGHT: (C)2009,JPO&INPIT |
