Electrical discharge type air cleaner

An electrical discharge type air cleaner comprising:

• a dust collecting tank configured to accommodate a liquid;
• a housing configured to accommodate the dust collecting tank;
• an air supplying portion configured to supply air from an outside into the dust collecting tank to collect pollutants contained in the air;
• an air discharging portion having an air discharging tube disposed so as to face a surface of the liquid, and configured to discharge the air supplied to the dust collecting tank to the outside;
• a plurality of discharge electrodes disposed along a circumference of the air discharging tube;
• a charging portion disposed in the dust collecting tank and charging the liquid with a polarity opposite to a polarity of the plurality of discharge electrodes such that an electric field is formed between the plurality of discharge electrodes and the liquid and the pollutants are collected into the liquid;
• and
• a rotary vane installed on a bottom of the dust collecting tank and configured to rotate the liquid such that a vortex is formed in the liquid,
• wherein the air cleaner is configured so that a spaced apart distance between the surface of the liquid and the plurality of discharge electrodes is within a predetermined distance range.
