PROBLEM TO BE SOLVED: To provide a fan that can blow air including ions to the direction of an odor source in a space and is easy to use.SOLUTION: A fan installed in a ceiling includes a shutter 8 which fully opens an opening portion 2 or closes a part of the opening portion 2 except a sectorial portion, a shutter rotating means 9 of driving and rotating the shutter 8 at the opening portion 2, a shutter opening/closing means 10 of adjusting the opening angle of the shutter 8, and a control portion 11 which controls the opening direction and opening angle of the opening portion 2 by making the shutter rotating means 9 and shutter opening/closing means 10 operate, and blows air including ions to an indoor space by making a fan motor 5 and an ion generation portion 7 operate. The shutter rotating means 9 and shutter opening/closing means 10 are placed in operation according to a signal from an odor detection portion 6, and the opening area of the opening part 2 is reduced to control a shutter opening direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】空間内の臭いのもとの方向にむけてイオンを含んだ空気を当てることができる使い勝手の良い送風機を提供することを目的とする。【解決手段】天井に設置される送風機において、開口部2で全開または扇形の部分を残し、開口部2の残りの部分を閉止するシャッター8と、開口部2でシャッター8を回転駆動させるシャッター回動手段9と、シャッター8の開口角度を調整するシャッター開閉手段10と、シャッター回動手段9とシャッター開閉手段10を動作させて開口部2の開口方向および開口角度を制御しファンモータ5とイオン発生部7を動作させて室内空間にイオンを含んだ空気を送る制御部11を備え、臭い検知部6からの信号をもとにシャッター回動手段9とシャッター開閉手段10を動作させ、開口部2の開口面積を絞ることでシャッター開口方向を制御する。【選択図】図1
