1. An electrification apparatus for electric dust collection, comprising:
a frame;
a conductive microfiber disposed in the frame and configured to generate ions in air; and
conductive plates disposed in the frame and configured to generate a potential difference with the conductive microfiber;
an electric wire connected to the conductive microfiber and configured to apply a high voltage to the conductive microfiber,
wherein the frame comprises:
a main body frame that accommodates the conductive plates, and
an installation frame that defines a fixing groove configured to receive the conductive microfiber,
wherein the electrification apparatus further comprises a rubber structure coupled with the conductive microfiber and configured to insert into the fixing groove, the rubber structure having a cylindrical shape and defining an inner opening that surrounds an outside of the conductive microfiber or the electric wire,
wherein the installation frame comprises:
a first installation surface that defines the fixing groove,
a second installation surface that extends downward from a first side of the first installation surface, the second installation surface defining an installation hole configured to receive the rubber structure and the electric wire, and
a third installation surface that extends downward from a second side of the first installation surface, and
wherein the first installation surface, the second installation surface, and the third installation surface define an installation space that accommodates and covers the electric wire.
