Apparatus and method for controlling cool air in refrigerator

An apparatus for controlling cool air in a refrigerator comprising:

• a blowing chamber having a blowing fan for compressing the cool air;
• a damper penetrating a compartment wall and leading for a certain length to introduce the cool air from the blowing chamber;
• and
• the cool air discharging means which moves from the front of a refrigerating chamber to the position of a load to discharge the introduced cool air.

A system for controlling cool air in a refrigerator comprising:

• varying means for operating in all directions according to opening/closing of a refrigerator door;
• detecting means for detecting surrounding temperature according to the operation of the varying means;
• controlling means for judging whether the detected surrounding temperature reaches a certain degree or higher to control injection of the cool air;
• and
• cool air discharging means for injecting the cool air in the front of a refrigerating chamber if the detected surrounding temperature reaches the certain degree or higher.

A method of controlling cool air in a refrigerator, the method comprising the following steps of:

• operating varying means in all directions according to opening/closing of a refrigerator door;
• if the varying means are operated in all directions, detecting surrounding temperature to judge whether the surrounding temperature reaches a predetermined degree or higher;
• and
• if the surrounding temperature reaches the predetermined degree, injecting the cool air.
