PROBLEM TO BE SOLVED: To provide an air purifier which determines an appropriate amount of a water screen on the basis of an odor concentration in a space and removes odor and the like.SOLUTION: An air purifier includes: a body case 1 provided with an air inlet 2 and an air outlet 3 an air duct making the air inlet 2 and the air outlet 3 communicate with each other air blowing means 4 blowing air to the air duct a rotatable cylindrical air purification filter 5 mounted so as to block the air duct a partition wall 7 partitioning the air duct to an air inflow side and an air outflow side of the air purification filter 5 and a water tank 6 allowing the lower part of the air purification filter to be immersed into water. The air purification filter 5 is configured such that a water screen 8 is formed when the air purification filter 5 comes out of the water tank 6 according to its rotation, and includes a detection part 9 measuring the amount of the water screen and a control part 10 varying the rotation speed of the air purification filter, and thereby varies the rotation speed of the air purification filter 5 on the basis of the amount of the water screen 8 formed on the air purification filter 5.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】空間の臭気濃度に基づいて適切な水膜の量を判断し、臭気等の除去を行う空気清浄装置を提供することを目的とする。【解決手段】吸気口2と吹出口3を設けた本体ケース1と、前記吸気口2と前記吹出口3を連通する空気風路と、前記空気風路へ空気を流す送風手段4と、前記空気風路を遮るように設けた回転可能な円筒形状の空気清浄フィルタ5と、前記空気風路を前記空気清浄フィルタ5の空気流入側と空気流出側とに仕切る隔壁7と、前記空気清浄フィルタの下部を水に浸すことのできる水槽6とを備え、前記空気清浄フィルタ5は、前記空気清浄フィルタ5が回転に伴い水槽6から出る際に水膜8が形成される空気清浄フィルタ5を有し、前記水膜の量を測定する検知部9と、前記空気清浄フィルタの回転速度を変化させる制御部10を備え、前記空気清浄フィルタ5上に形成されている水膜8の量に基づいて、空気清浄フィルタ5の回転速度を変化させるものである。【選択図】図3
