PROBLEM TO BE SOLVED: To provide an air purification device capable of enhancing sterilization and deodorization performance.SOLUTION: An air purification device comprises a body case provided with an inlet port 2 and an outlet port. The air purification device also has, in the body case, air purification means, an air passage 12 communicating the inlet port 2 with the outlet port through the air purification means, and blast means 4 to supply air to the air passage 12 through the inlet port 2. The air purification means has: a tray 6 to store water an electrolytic unit 8 which changes the water in the tray 6 into electrolytic water a filter section 9 which is formed into a rotatable hollow cylinder and arranged so as to be partially immersed in the electrolytic water and preliminary humidification means 14 which performs preliminarily humidification of a gap between the inlet port 2 and the filter section 9 in a manner that prevents the electrolytic water from being evaporated and released from the filter section 9.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】本発明は、除菌、脱臭性能を高めることができる空気浄化装置を提供する。【解決手段】吸気口2と吹出口とを有した本体ケースと、本体ケース内には、空気浄化手段と、吸気口2から空気浄化手段を介して吹出口までを連通する空気流路12と、空気流路12に吸気口2から空気を送風する送風手段4とを備え、空気浄化手段は、水を貯水するトレイ6と、トレイ6内で水を電解水へ生成する電解ユニット8と、中空円筒状にして回転可能に形成し前記電解水に一部が浸漬するように配置したフィルター部9と、吸気口2とフィルター部9の間隙に予備加湿を行う前加湿手段14を設け、気化に伴うフィルター部9からの再放出を抑制する。【選択図】図3
