To provide an air purification device having high cleanness of blowing air by increasing a cleaning effect of taken-in air in a main body in a sterilizer for purifying air in a main body by installing a tray in the main body, immersing a filter in hypochlorous acid water filled in the tray, and exposing air taken in through a suction opening to a filter member impregnated with the hypochlorous acid water.SOLUTION: A return air path 18 is provided so as to communicate from the air path after passing through a gas-liquid contact filter 7 to an upstream side of the gas-liquid contact filter 7, a blowing portion 6 is installed between the upstream side of the gas-liquid contact filter 7 and the return air path 18, and a part of the air having passed through the gas-liquid contact filter 7 is drawn from the return air path 18 to the upstream side of the gas-liquid contact filter 7, whereby an amount of air ventilated to the gas-liquid contact filter 7 increases, so that a cleaning effect in an air purification device 1 is improved to increase cleanness of blowing air.SELECTED DRAWING: Figure 2【課題】本体内にトレイを設け、そのトレイに満たされた次亜塩素酸水にフィルタを浸水させ、次亜塩素酸水を含浸させたフィルタ部材へ吸込口より取り込んだ空気を曝露させることで、本体内で空気の浄化を行う殺菌装置において、取り込んだ空気の本体内での清浄化効果を高めることで、吹き出し空気の清浄度が高い空気浄化装置を提供する。【解決手段】帰還風路１８は気液接触フィルタ７を通過した後の風路から前記気液接触フィルタ７の上流側に連通するように備えられ、送風部６は、前記気液接触フィルタ７の上流側と前記帰還風路１８の間に設置し、前記気液接触フィルタ７を通過した空気の一部を前記帰還風路１８から前記気液接触フィルタ７の上流側に引き込むことにより、気液接触フィルタ７へ通気される空気が多くなるため、空気浄化装置１内における清浄効果が向上することにより、吹き出し空気の清浄度が向上させることができる。【選択図】図２
