The present invention relates to a dust collecting filter and a method for manufacturing a dust collecting filter. The dust collecting filter of the present invention may comprise: a filter medium collecting foreign substances in the air; a plurality of first conductive threads sewn to the filter medium and to which a high voltage is applied; and a plurality of second conductive threads sewed to the filter medium, disposed between the plurality of first conductive threads, and grounded.

Dust collection filter and dust collection filter manufacturing method

The present invention relates to a dust collecting filter. The dust collecting filter of the present invention may include a ground electrode unit bent in a corrugated shape to form a plurality of bent portions and a plurality of flat portions between each of the plurality of bent portions, and grounded; and a plurality of voltage electrode units disposed between each of the plurality of flat portions and spaced apart from each other, and to which a high voltage is applied.

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.

Electrostatic precipitation type air cleaner

An electric dust collecting device and an air conditioner having the same are disclosed. The electric dust collecting device includes a first filter unit including a plurality of discharge electrode plates which are spaced apart from each other and have spaces defined therebetween, a high voltage generator electrically connected to all of the plurality of discharge electrode plates, and a second filter unit disposed downstream of the first filter unit in an air flow direction and connected to a ground to cause corona discharge between the discharge electrode plates and the second filter unit, whereby particles electrically charged by corona discharge are collected at the second filter unit. The first filter unit has a simplified structure, and cleaning effect is improved.
