Abstract:
A control method of a cool air exhaling apparatus in an enforced circulation type refrigerator in which a cool air cooled by an evaporator is guided to a duct by operating a cool air circulating fan and is exhaled into the refrigerator through a cool air exhaling hollow formed in a duct cover, wherein at least one cool air guide having a cool air exhaling hollow in an inner sidewall is formed protrusively at the front of said duct cover along a width direction of the refrigerator, and a duct thermal insulation material has a cool air guide hollow formed in sides of said duct cover so that the cool air flows down at the front of the refrigerator, said cool air guide hollow having a convex curved side portion connected to the inner sidewall of said cool air guide, the control method comprising the steps of:sensing a temperature in the refrigerator;turning off a compressor and said cool air circulating fan if the temperature in the refrigerator is lower than a predetermined temperature;turning on said compressor and said cool air circulating fan if the temperature in the refrigerator is higher than the predetermined temperature; andturning on said cool air circulating fan regardless of the temperature in the refrigerator in the event' of opening a door of the refrigerator.
