Zusammenfassung:To provide an air blower which can suppress the disturbance of a planar airflow due to a backflow airflow in a closed dwelling room space.SOLUTION: An air blower 1 comprises: a dwelling room space 26 having a floor face (floor board 12), a wall face (side panel 14) erecting from the floor face, and a ceiling face (top board 16) opposing the floor face; a plurality of nozzles 60 arranged with spaces between the ceiling face and themselves, and blowing out an airflow toward the floor face; an induction air duct 70 for making an induction airflow AF2 circulate therein; and a backflow air duct 80 for making a backflow airflow AF3 circulate therein. The induction air duct 70 is arranged between the adjacent nozzles 60, and the backflow air duct 80 is arranged between the wall face and the nozzles 60. In the air blower 1, a distance between the wall face forming the backflow air duct 80 and the nozzles 60 is elongated compared with a distance between the adjacent nozzles 60 forming the induction air duct 70.SELECTED DRAWING: Figure 3 【課題】閉じた居室空間において面気流の流れが還流気流により乱れることを抑制可能な送風装置を提供する。【解決手段】送風装置1は、床面(フロアボード12)と床面から立設する壁面(サイドパネル14)と床面に対向する天面(トップボード16)とを有する居室空間26と、天面との間に空間を設けて配置され床面へ向けて気流を吹き出す複数のノズル60と、誘引気流AF2を流通する誘引風路70と、還流気流AF3を流通する還流風路80と、を備える。誘引風路70は、隣り合うノズル60の間に設けられ、還流風路80は、壁面とノズル60との間に設けられる。送風装置1は、誘引風路70を形成する隣り合うノズル60の間の距離に比べて還流風路80を形成する壁面とノズル60との間の距離を大きくした。【選択図】図3
