PROBLEM TO BE SOLVED: To provide a mist generating device which prevents discharge of large water droplets to the indoors.SOLUTION: A mist generating device includes: a device body 1 a water storage chamber 8 installed in the device body 1 and for storing a predetermined amount of water a mist generating part 15 for sucking the water in the water storage chamber 8 by a centrifugal force by rotation, for dispersing and crushing it, and for generating nano-mist and negative ions a blower fan 16 for allowing dust powder and dust in the air to be captured in the water in the water storage chamber 8 by passing the sucked indoor air through the mist generating part, and for supplying the cleaned air to the indoors together with the nano-mist and the negative ions and an air-water separation part 19. The air-water separation part 19 is configured by two pieces of baffle plates 20, 21. The first baffle plate 20 on the lower side is inclined upward, and by folding the end part on the central side upward, a first baffle 22 protruding to the upper part is formed. Furthermore, the second baffle plate 21 on the upper side is inclined upward, and by folding the end part of the central side downward, a second baffle 23 protruding to the lower part is formed.COPYRIGHT: (C)2016,JPO&INPIT【課題】大粒の水滴の室内への放出を阻止するミスト発生装置を提供する。【解決手段】器具本体1と、該器具本体1内に設置され所定量の水を貯水する貯水室8と、該貯水室8内の水を回転による遠心力で吸い上げて飛散させて破砕し、ナノミストと負イオンを発生させるミスト発生部15と、吸引した室内空気をミスト発生部を通すことで空気中の塵、埃を貯水室8の水の中に捕集させると共に、浄化された空気をナノミストと負イオンと共に室内に供給する送風ファン16と、気水分離部19とを備えたもので、前記気水分離部19は2枚のバッフル板20、21で構成され、下側の第1バッフル板20は上向きに傾斜しており、その中央側の端部を上向きに折り曲げて上部に突出する第1邪魔板22が形成され、更に上側の第2バッフル板21は上向きに傾斜しており、その中央側の端部を下向きに折り曲げて下部に突出する第2邪魔板23を形成した。【選択図】 図2
