ABSTRACT:
A cool air regulator structure of a refrigerator regulates the quantity of cool air supplied into a freezing compartment and a fresh food compartment by driving a driving part. Cool air return ducts are formed within a separating plate between the freezing compartment and fresh food compartment, and an air variable blade swinging by the driving part is provided to the rear side of the cool air return ducts. When a temperature of the freezing compartment is higher than a preset temperature and a temperature of the fresh food compartment reaches a preset temperature, temperature sensors sense the current temperature status to drive the driving part, thereby swinging the air variable blade downward. The quantity of cool air is adjusted by the swinging of the air variable blade upward in the contrary manner; otherwise, the air variable blade maintains the neutral position thereof.
