Abstract:
A centrifugal fan, comprising: a housing (20) in which an air inlet space which is in communication with an air inlet, and a plurality of air discharging ducts which extend in a curved manner, are defined; a vane wheel (30), configured such that an air flow flows into the housing (20) from the air inlet and flows out from the housing (20) via one or more air outlets; a plurality of flaps (40) for adjusting air discharging areas of the plurality of air outlets or air discharging ducts, respectively; a rotary member (50); and a driving mechanism (60), configured to transfer the rotary motion of the rotary member (50) to the plurality of flaps (40), such that the plurality of flaps (40) move to their respective blocking positions. The centrifugal fan can, by means of the rotation of the rotary member (50), drive the flaps (40) to move to controllably block the plurality of air outlets, realizing simultaneous air blowing in multiple directions. Moreover, the centrifugal fan can choose a direction to discharge air and adjust the amount of air discharged by each air outlet, realizing appropriate air blowing.
