PURPOSE: An air cleaner using a water film is provided to effectively remove dust such as micro particles using the minimum amount of water by a mechanical colloidal effect.CONSTITUTION: An air cleaner using a water film comprises: an air inlet(10) in which air is flowed in with dust a water inlet in which water is flowed in a water path(20) in which the inflow water forms a water film inside of a wall while the air flows a whirlpool induction part(30) in which the inflow air forms a vortex within the water path and a water extraction part(40) which is positioned on the water path. Dust in the air collides with the water film on the water path, and is extracted through the water extraction part with the water film.COPYRIGHT KIPO 2013본 발명은 먼지와 함께 유입된 공기가 와류를 형성하면서 내측면에 워터필름이 형성된 유로에 충돌하도록 하여, 효과적인 공기 정화가 이루어지도록 하는 공기 정화 장치를 제공한다. 본 발명에 의하여 극소량의 물을 사용하여 미세입자에 대한 효과적인 공기 정화 성능을 이룰수 있다.
