Circulating fan unit

Abstract

This invention provides a circulating fan device that combines improved indoor circulation efficiency with miniaturization. The circulating fan device includes: a rotating component that rotates axially via a drive source; and an air guide component disposed radially on the outer periphery of the rotating component, having an air intake on a first side facing the rotating component, a plurality of exhaust ports on a second side arranged circumferentially, and a plurality of air guide sections connecting the air intake and the plurality of exhaust ports. The rotating component includes a base plate portion disposed radially inner to the air guide component, a boss portion disposed at the center of the first side of the base plate portion and protruding towards the first side, and a plurality of blade portions arranged circumferentially along the base plate portion. The rotating component forms an air guide path between the outer peripheral surface of the boss portion, the surface of the first side of the base plate portion, and each adjacent pair of the plurality of blade portions, guiding airflow from the axial direction to the radially outer side corresponding to the exhaust ports.
