Title:
DUST COLLECTING APPARATUS AND AIR-CONDITIONING APPARATUS
Document Type and Number:
WIPO Patent Application WO2001064349
Kind Code:
A9
Abstract:
Power consumption and ozone generating rate are suppressed to the utmost by charging dust particles using an ion emitting means that emits ionized air exclusively without causing corona discharge. Conventional dust collecting apparatuses of electrostatic precipitator type are constituted by a charging unit consisting of a discharge electrode and an earth electrode, a dust collecting unit consisting of a voltage applying electrode plate and an earth electrode plate, and a blowing fan, in order. Dust particles introduced in the dust collecting apparatus are charged by ionized air generated by breaking the insulation of air by corona discharge caused in the charging unit and eliminated by the dust collecting unit which forms an electric field. Therefore there has been a problem of large power consumption and a large ozone generating rate, which are attributed to the large discharge current caused by the corona discharge caused in the charging unit.
