Abstract
A surface discharge type air cleaning device including an insulating dielectric body formed in the shape of a sheet, a discharge electrode formed at the upper surface of the insulating dielectric body, and a ground electrode formed at the lower surface of the insulating dielectric body. The discharge electrode is formed of a closed pattern having a predetermined area on the upper surface of the insulating dielectric body. The discharge electrode has a non-pattern part disposed in a pattern part where the pattern is formed. The electrode is not formed at the non-pattern part. The ground electrode is formed at a predetermined position corresponding to the non-pattern part. The area of the non-pattern part is reduced to decrease generation of ozone, and the area of the pattern part is enlarged to increase generation of negative ions and hydroxyl radicals. Consequently, the number of negative ions and hydroxyl radicals is increased while the amount of ozone is decreased, and therefore, air cleaning efficiency is improved.
