    Abstract: An electric dust collecting device according to the invention includes an electric charging unit for electrically charging dust in air, a first filter unit including a plurality of discharge electrode plates spaced apart from each other to define passages therebetween through which dust electrically charged by the electric charging unit passes, and a second filter unit disposed downstream of the plurality of discharge electrode plates in an air flow direction and connected to a ground to cause corona discharge between the plurality of discharge electrode plates and the second filter unit and to collect electrically charged dust. Dust particles electrically charged by the electric charging unit pass through the passages of the first filter unit and then are collected at the second filter unit, and dust particles electrically charged between the first filter unit and the second filter unit are electrically charged by the second filter unit, thus improving electric charging efficiency and dust collecting efficiency.

    Abstract: An electrostatic precipitation type air cleaner is disclosed herein. The air cleaner includes a charging module to charge dust particles by applied power and a collection module to collect the dust particles charged by the charging module. The collection module includes high voltage electrode plates and low voltage electrode plates disposed opposite the high voltage electrode plates so as to form air passages with the high voltage electrode plates, at least one of the high voltage electrode plates and the low voltage electrode plates includes a conductive member, a dielectric member to surround at least a part of the conductive member and coating layers configured to coat the surfaces of the dielectric member, and the coating layer includes 0.5 w % to 5 w % of zinc oxide. The coating layer including 0.5 w % to 5 w % of zinc oxide may have high antimicrobial activity and maintain high surface hardness.
