IPC: B01D47/00

Abstract: The present invention relates to an air cleaner which removes pollutants in indoor air using water rather than a filter. In order to clean air with water, when water in a water tank is rotated using a bar-shaped stirring member (30), water above the stirring member (30) goes down and rotates according to the rotary direction of the stirring member (30) to be pushed onto the wall of the water tank and then move up along the wall, and this whole process is repeatedly performed. When water in the water tank is rotated by the rotation of the stirring member (30), air is drawn into water as the pressure above the stirring member (30) decreases. Here, the flowing velocity of water becomes slower in a location farer from the stirring member (30), which causes the flowing velocity of water to be different at locations, thus air sucked into water is fragmented. As the surface area of the air fragmented into small bubbles becomes wider, a significant portion of pollutants contained in the air is removed by water. The present invention is devised to improve air cleaning efficiency by installing an additional device for air inlet, such as an air sucking port (11), in order for air bubbles fragmented in the water tank not to be mixed with air flowing into the water tank when escaping from the water tank.
