<p>PROBLEM TO BE SOLVED: To enable sufficiently supply of negative ion, which is good for health, in spite of a compact structure. SOLUTION: This air cleaner enables supply of negative into while collecting dust. In such a case, a charging part 3 for charging dust or the like, a dust collecting part 4 for adsorbing the charged dust and a sucking and blowing part 7 are arranged in this order from the upstream side in a casing C, a discharge wire 14 is arranged so as to cross an air duct 13 between the dust collecting part 4 and the sucking and blowing part 7, a flow straighting part 15 swelled out from the inside surface of the casing C along the discharge wire 14 is formed and an earthed part 16 is provided to face discharge wire 14 in the flow straighting part 15.</p> |
