Abstract: An electrical discharge type air cleaner is provided. The air cleaner includes a dust collecting tank accommodating liquid, a housing accommodating the dust collecting tank, an air supplying portion supplying air to the dust collecting tank, an air discharging portion discharging the air from the dust collecting tank and having an air discharging tube facing a surface of the liquid, a plurality of discharge electrodes disposed at the air discharging tube, a charging portion in the dust collecting tank, and a rotary vane forming a vortex in the liquid. The charging portion charges the liquid with a polarity opposite to a polarity of the discharge electrodes such that an electric field is formed between the discharge electrodes and the liquid and pollutants in the air are collected into the liquid. A distance between the surface of the liquid ad the discharge electrode is maintained within a predetermined distance range.

Abstract: The present disclosure relates to a double swirl type air purifier including: a main body configured to accommodate a liquid for purifying an inflow air; a suction part located at one side of the main body and configured to suction the inflow air; and a discharge part located at a predetermined position of the main body and configured to discharge an outflow air introduced from the main body. The main body includes a rotation part located at a lower portion of the main body and configured to rotate the liquid. A contact area between the liquid swirled by the rotation part and the inflow air swirled by inflow pressure of the suction part is increased so as to improve air purification efficiency.

Abstract: The disclosure relates to a wave vortex air purifier. The wave vortex air purifier according to an embodiment includes an air inhaler configured to inhale air from an outside; a liquid storage configured to accommodate liquid for collecting contaminants contained in intake air inhaled through the air inhaler; a liquid fluidizer placed inside the liquid storage and configured to rotate inside the liquid storage to rotate the liquid in the liquid storage and cause an upwelling phenomenon that a level of the liquid changes; a rotary driver configured to rotate the liquid fluidizer; and an air discharger configured to discharge purified air, from which the contaminants are removed, to the outside.
