Abstract
A method for controlling opening/closing of cool air discharge ports of a refrigerator is disclosed. The refrigerator has a device for opening/closing the ports. The device has a member for opening/closing the ports, and a motor for driving the member. A microcomputer measures temperatures at positions in a cooling compartment, and calculates a difference between the measured temperatures. When the difference is more than a predetermined value, the motor is driven so that the member repeats opening and closing of the ports. Then, the circulation effect of the cool air in the cooling compartment is enhanced, and the temperature in the cooling compartment maintained uniform.
