A centrifugal fan includes: a housing installed at both sides of a driving motor and having an air suction opening and an air discharge opening; an impeller installed inside the housing and discharging air sucked through the air suction opening through the air discharge opening while being rotated by the driving motor; a motor bracket coupled to one side of the housing and connecting the housing the driving motor; and a noise reducing unit for minimizing a noise of air discharged to the air discharge opening.

Centrifugal fan

A blower apparatus which is used inside an Over-The-Range (OTR) microwave oven and the like, includes a centrifugal fan, a bracket which is fixed and combined with a side of the driving unit and a fan housing having a suction port which rotably accommodates the centrifugal fan, is fixed and combined with the bracket, and is formed in the shaft direction of the centrifugal fan, for sucking gas by rotation of the centrifugal fan, and a discharge port for discharging gas which is sucked through the suction port, being formed vertically to the suction port. The edge of the discharge port is formed in a convex shape in the shaft direction by the first inclined surface of a protrusion portion which is protruded in the shaft direction from the bracket and second inclined surface formed in the fan housing, and an inflection point is formed at the contact point of the first inclined surface and second inclined surface.
