Abstract: 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.

Abstract: 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.

Abstract: 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 include: a first filter medium that is bent into a corrugated shape and forms a plurality of bent portions; a plurality of first electrodes disposed on one surface of the first filter medium along the corrugated shape of the first filter medium and to which a high voltage is applied; and a plurality of second electrodes disposed along the corrugated shape of the first filter medium so as to be spaced apart from each other between the plurality of first electrodes and are grounded.

Abstract: 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.
