PROBLEM TO BE SOLVED: To provide an air blowout device with a simple configuration which can adjust a flow direction of a blowout airflow and a degree of convergence and diffusion.SOLUTION: The air blowout device includes: a housing 21 for defining an air flow passage 22 and a blowout port 23; a wind direction adjustment plate 31 capable of adjusting a flow direction of air blown out of the blowout port; and ventilation amount adjustment plates 41, 42 capable of adjusting an amount of air passing through the air flow passage. The air flow passage includes: a first flow passage 22a opening to a blowout port central part; a second flow passage 22b and a third flow passage 22c arranged so as to sandwich the first flow passage, and opening to an outer peripheral part of the blowout port. A flow passage area of an opening end of each of the second flow passage and the third flow passage is smaller than a flow passage area of an opening end of the first flow passage. The wind direction adjustment plate is supported in the first flow passage in a rotatable manner. The ventilation amount adjustment plates can adjust a flow rate in a range from a first state for allowing the ventilation of only the first flow passage, leading to a third state for allowing ventilation of none of the first flow passage, the second flow passage and the third flow passage, via a second state for allowing all ventilation of the first flow passage, the second flow passage and the third flow passage.SELECTED DRAWING: Figure 1
【課題】吹き出し空気流の流れ方向及び収束・拡散の度合いを調整可能な簡易な構成の空気吹出装置の提供。【解決手段】空気流路22及び吹出口23を画成する筐体21、吹出口から吹き出される空気の流れ方向を調整可能な風向調整板31、空気流路を通る空気の量を調整可能な通気量調整板41,42を備える。空気流路は吹出口中央部に開口する第1流路22aと、第1流路を挟むように配置され且つ吹出口の外周部に開口する第2流路22b及び第3流路22cを含む。第1流路の開口端の流路面積よりも第2流路及び第3流路の各々の開口端の流路面積が小さい。風向調整板は、第1流路内に回動可能に支持される。通気量調整板は、第1流路だけの通気を許可する第1状態から、第1流路、第2流路及び第3流路の全ての通気を許可する第2状態を経て、第1流路、第2流路、第3流路のいずれの通気も許可しない第3状態に至る範囲内において流量を調整可能とする。【選択図】図1
