しかし、集塵装置２２を備えなくてもよい。According to the dust collector 10 described above, the charged dust does not adhere to the fins 16 which are members to be protected from dust, and thus it is possible to prevent the dust from accumulating on the fins 16 and the chamber 14 as well. The dust in the chamber 14 can be gradually removed by the dust collector 22 to gradually purify the air in the chamber 14.
However, the dust collector 22 may not be provided.

ン１６への塵埃の付着を確実に防止することができる。According to the dust collector 10 described above, dust in the air is charged in the process of passing through the case 28. Therefore, compared to the case where the fin 16 and the charging member 30 are arranged in the same space. It is possible to reliably charge the dust and reliably prevent the dust from adhering to the fins 16.

部材として配置してもよい。In the dustproof device 10, the closer the charging device 20 is located to the air inflow part to the fins 16, the less the uncharged dusts reaching the fins 16 are, and the amount of dusts adhering to the fins 16 is reduced. It can be surely prevented. Therefore, the charging device 20 may be disposed in the same case as the fin 16 and on the air inflow side to the case as a member of the air conditioner.

の一部材として配置してもよい。Similarly, the closer the dust removing device 22 is located to the air outflow portion from the fins 16, the more reliably the dust in the air flowing out from the air conditioner can be removed. Therefore, the dust removing device 22 may be arranged in the same case as the fins 16 and on the air outflow side from the case as one member of the air conditioner.

May be omitted. Further, the voltage on the secondary side of the step-up transformer 48 may be floated regardless of the ground potential, that is, without connecting the middle point of the secondary-side coil of the step-up transformer 48 to the ground.
