摘要： 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.
