Airflow diffuser (diffuser fan) and air conditioner

摘要

An airflow diffuser (diffuser fan) comprises: a blade wheel formed of blade members 30, spoke members 40 and a hub member 50; a shaft member 20 forming an axis of rotation of the blade wheel; and a suspension member 10 suspending the shaft member 20 from a ceiling surface. This airflow diffuser (diffuser fan) is located so that air blown out from the air outlets of an air conditioner comes in contact with and rotates the blade members. Also, the rotating blade members receive the blown air in succession, and by deflecting the air, diffuse the blown air throughout the entire air-conditioned space.
