送風機。In a centrifugal blower equipped with an impeller with a large number of small blades arranged on the circumference and a spiral casing that forms a wind guide around the impeller, the shape of the spiral casing is determined by the progression of the spiral. A blower characterized in that, in contrast to the theoretical shape of the inner wall whose radius increases at a constant rate depending on the angle, an enlarged flow passage portion connected by a smooth curve is provided at at least one location on the inner wall.
