Title:
ION GENERATOR AND AIR CONDITIONER USING SAME
Document Type and Number:
WIPO Patent Application WO/2005/020397
Kind Code:
A1
Abstract:
An ion generator for generating ions at high concentration to produce an excellent air-cleaning effect, and an air conditioner using the same are disclosed. The ion generator (17) is characterized in that opposed electrodes sandwiching a dielectric body (13) are povided, a positive or negative voltage varying with time is applied between the electrodes, and thereby ions are produced. The maximum value of the rate of increase or decrease of the time-varying voltage is preferably 150 V/msec or more. The waveform of the time-varying voltage is preferably the superposition of a DC waveform and a time-varying waveform. The ion generator is preferably applied to an air conditioner (11) for sending cations and/or anions into the air.
