PROBLEM TO BE SOLVED: To provide a fine particle diffusion device capable of heightening the density of fine particles in a living space while easing the discomfort feeling of a user.SOLUTION: The fine particle diffusion device includes: a suction port 2a that opens at the front surface of a case 2 and sucks in air in a room a first blowing path 4c through which an air flow sucked in from the suction port 2a flows and is blown forward via a first discharge port 2c formed at the case 2 a second blowing path 4d through which the air flow sucked in from the suction port 2a flows and is blown in a different direction than the first discharge port 2c via a second discharge port 2d formed at the case 2 and a fine particle generation device 10 that generates fine particles and discharges the particles in the first blowing path 4c.COPYRIGHT: (C)2013,JPO&INPIT【課題】使用者の不快感を低減して居住空間の微小粒子の濃度を高くできる微小粒子拡散装置を提供する。【解決手段】筐体2の前面に開口して室内の空気を吸い込む吸込口2aと、吸込口2aから吸い込まれた気流が流通するとともに筐体2に開口した第1吹出口2cを介して前方に送出する第1送風路4cと、吸込口2aから吸い込まれた気流が流通するとともに筐体2に開口した第2吹出口2dを介して第1吹出口2cと異なる方向に送出する第2送風路4dと、微小粒子を発生して第1送風路4cに放出する微小粒子発生装置10とを備えた。【選択図】図1
