Abstract
A multiblade fan includes an impeller including a rotating plate and blades and further includes a fan casing having a circumferential wall and a first end face disposed adjacent to distal ends of the blades. The first end face has an inlet. The multiblade fan further includes a duct and a flow regulating block disposed on an inner surface of the first end face. The flow regulating block regulates a flow of the air. The duct includes a diffuser plate. The circumferential wall includes a tongue that is connected to the diffuser plate. The first end face has a bell mouth provided at the inlet. The flow regulating block is spaced from the circumferential wall and extends along the bell mouth in the rotation direction such that the flow regulating block is located in a range of 120 degrees from a reference position on a line connecting the rotary shaft to a tip of the tongue.
