ABSTRACT:
Disclosed is a refrigerator having cool air dispersing blades. The blades are rotatably disposed near cool air discharge ports in a duct. The discharge direction of the cool air is determined by angular positions of the blades. The blades are driven by a motor capable of controlling an angular position thereof. A microprocessor controls the motor so that the angular position of the blades is successively changed with a predetermined time interval. Then the temperature of the compartment is maintained uniform effectively.
