1. An electric precipitator comprising:
an electric charging part receiving a first high voltage applied thereto and applying electric charges to dust; and
a precipitating part including first precipitating plates to which a first low voltage having a lower level than the first high voltage is applied and second precipitating plates to which a second high voltage having a higher level than the first low voltage is applied, in order to precipitate the dust charged in the electric charging part,
wherein the electric charging part is disposed to be farther spaced apart from the second precipitating plates than the first precipitating plates in a portion or entirety thereof,
wherein the precipitating part includes a first fixing member including first supports elongated in the length direction to fix positions of the first precipitating plates,
wherein the precipitating part includes a second fixing member including second supports elongated in the length direction to fix positions of the second precipitating plates,
wherein the first precipitating plates has first insertion grooves which are formed at one side thereof in a width direction and into which the first supports of the first fixing member are inserted and fixed and has first cut-out grooves which are formed at the other side thereof in the width direction and at which the second supports of the second fixing member are positioned, and
the second precipitating plates has second cut-out grooves which are formed at one side thereof in the width direction and at which the first supports of the first fixing member are positioned and has second insertion grooves which are formed at the other side thereof in the width direction and into which the second supports of the second fixing member are inserted and fixed,
wherein the first insertion grooves are formed in a size corresponding to the first supports, so that the first supports are inserted and fixed in the first insertion grooves,
the first cut-out grooves are formed larger than the second supports to prevent electrical connection while the second supports are inserted, so that the second supports and the first cut-out grooves are spaced apart from each other,
the second insertion grooves are formed in a size corresponding to the second supports, so that the second supports are inserted and fixed in the second insertion grooves, and
the second cut-out grooves are formed larger than the first supports to prevent electrical connection while the first supports are inserted, so that the first supports and the second cut-out grooves are spaced apart from each other.
