Refrigerator having a device for opening/closing cool air discharge ports

摘要

A refrigerator is disclosed which is capable of preventing heat exchange between an evaporator and an outside air during a defrosting operation and/or when a door is open. The refrigerator has a device for opening/closing cool air discharge ports formed at a cool air duct. The opening/closing device includes opening/closing member for opening/closing the cool air discharge ports and a driving device for driving the opening/closing member. The cooling efficiency is enhanced and the frost caused by the outside air is not generated on the evaporator.
