<p>Disclosed herein is a blowing apparatus for refrigerators. The blowing apparatus includes a centrifugal fan (60). The centrifugal fan (60) comprises a hub plate (62) connected to a shaft of the motor (70), a plurality of blades (64) attached to the hub plate (62) in the radial direction of the hub plate (62) for forcing cool air to flow, and a ring-shaped shroud (66) connected to ends of the blades (64). The ratio (Di/Do) of the inner diameter (Di) of the centrifugal fan (60), formed through connection of the inner ends of the blades (64), to the outer diameter (Do) of the centrifugal fan (60), formed through connection of the outer ends of the blades (64), is 0.63 ±0.01.</p> |
