PROBLEM TO BE SOLVED: To solve the problem in which, in a conventional ventilation device, mold grows due to scattering and attachment to a ceiling of dirt fine particles which generate during bathing.SOLUTION: A bathroom ventilation device 1 is operated during bathing, and the air containing dirt sucked from a suction port 8 is purified by allowing the air to pass through air purification means 12, and an air flow is flowed along a ceiling surface from a circulation air blowout port 9. Thereby, dirt fine particles occurring during bathing are captured, and the fine particles attaching to the ceiling surface is suppressed by the airflow. Thus, the bathroom ventilation device 1 can be acquired which can continuously facilitate moisture drying and suppress growth of mold.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】従来の換気装置では、入浴中に発生する汚れ微粒子の飛散や天井へ付着により、カビが発生するという課題があった。【解決手段】入浴中に運転して、吸込み口８から吸込んだ汚れを含んだ空気を、空気浄化手段１２に通気させて浄化し、循環風吹出し口９から天井面にそって気流を流したことにより、入浴中に発生する汚れ微粒子を捕集して、さらに気流により微粒子が天井面に付着することを抑制することができるため、水分乾燥の促進、カビの発生を連続的に抑制することが可能となる浴室換気装置１を得られる。【選択図】図１
