An apparatus controls cool air for directedly cooling a section which is weakly cooled or which stores new loads. The apparatus discharges the cool air by rotating a drive body in accordance with a variation of visual images taken by visual image generator before and after the load is stored. The cool air can also be discharged into a specific storage space by rotating cool air injection nozzles based upon the temperature variation of door baskets detected by temperature sensors. Therefore, a uniform temperature distribution can be maintained in the cooling device to substantially reduce an amount of power consumption.

Apparatus and method for controlling cool air in refrigerator

The invention relates to a cool air controlling apparatus for concentrically cooling a region in a refrigerator where a new load is stored. The apparatus comprises: the first cool air duct provided along a compartment wall of a refrigerator with a certain length for allowing the cool air introduced from a blowing chamber to flow therethrough; the second cool air duct having a variable length provided downward from a front end of the first cool air duct; length adjusting means connected to the second cool air duct for adjusting the length of the second cool air duct; and rotation adjusting means attached to a lower end of the second cool air duct for carrying out rotation and injecting the cool air. The entire temperature distribution is uniformly maintained in a refrigerating chamber thereby greatly reducing power consumption.
