摘要
PURPOSE: A cold air flow structure for a refrigerator is provided to minimize noise and enable smooth flow of cold air by blocking the vortex of cold air.;CONSTITUTION: A cold air flow structure for a refrigerator comprises an orifice and a ventilation fan(200). The orifice comprises a cool air through-hole(110) guiding the cool air to the storage space of a refrigerator. The ventilation fan comprises a base plate(210), multiple blades(220), a shroud(230), and a bellmouth(240). The base plate is separated from one side of an orifice. The multiple blades are arranged according to the columnar direction of the base plate. The shroud keeps the rotation of the blade. The bellmouth is projected from the center of the base plate. A guide curvature part is formed on the outer circumference of the shroud facing to the orifice. A vortex blocking curvature part is formed on the orifice to correspond to the guide curvature part.;COPYRIGHT KIPO 2011
