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.
Claims8
A dust collecting filter, comprising:
- a filter medium that collects foreign substances in 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 sewn to the filter medium, disposed between the plurality of first conductive threads, and grounded, wherein the filter medium is bent into a corrugated shape, wherein the filter medium includes a plurality of flat portions for each of a plurality of bent portions, and wherein the plurality of first conductive threads and the plurality of second conductive threads pass through a first surface and a second surface of the plurality of flat portions and the plurality of bent portions alternately and are threaded through the filter medium.
A method for manufacturing a dust collecting filter, the method comprising:
- threading a plurality of first conductive threads and a plurality of second conductive threads to a filter medium so that the plurality of first conductive threads and the plurality of second conductive threads are alternately spaced apart from each other;
- forming a corrugation by bending the filter medium into a corrugated shape;
- and
- forming an electrode by connecting a power source for applying a high voltage to the plurality of first conductive threads and connecting a ground to the plurality of second conductive threads, wherein the filter medium includes a plurality of flat portions for each of a plurality of bent portions, wherein in the threading, the plurality of first conductive threads and the plurality of second conductive threads pass through a first surface and a second surface of the plurality of flat portions and the plurality of bent portions alternately and are threaded through the filter medium.
