ABSTRACT:
Disclosed is a method of controlling a cool air dispersing operation of a refrigerator for maintaining the temperature in a cooling compartment uniform. Many horizontal dispersing blades and vertical dispersing blades of planar plate shape, which respectively control the horizontal and vertical discharge directions of cool air are installed in a cool air duct. The blades are continuously rotated while a deviation of temperature in the cooling compartment is smaller than a predetermined value, whereby the cool air in the cooling compartment is successively supplied into the respective areas in the cooling compartment. Meanwhile, if the deviation is greater than the predetermined value, the blades are stopped at a specific position so that the cool air is discharged toward an area of which temperature is high. Thus, the temperature in the cooling compartment becomes uniform in a short period of time. Further, no vortex of cool air is generated since the blades are shaped into a planar plate.
