摘要： 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.

摘要： A refrigerator having a shutting device for preventing flow of air between an evaporator and a fresh food compartment is disclosed. The shutting device has a shutting member for shutting a space that the evaporator is installed against a cooling compartment, and a motor for driving the shutting member. During a defrosting operation and when the door is open, cool air discharge ports are closed by the shutting member. Thus, the temperature rise of the fresh food compartment due to the heat from a defrosting heater, and the loss of cool air and the generation of frost on the evaporator due to the opening of the door are prevented.
