ABSTRACT:
A method for controlling a defrosting operation of a refrigerator by providing a defrosting operation control method wherein a refrigerator use pattern by the user is learned. The defrosting operation control method based on the learning of the refrigerator use pattern comprises the steps of dividing a day, namely, 24 hours into a plurality of time intervals each corresponding to a predetermined period, for example, one hour, calculating the number of refrigerator door openings by time intervals, repeating the calculating step for predetermined days, storing information about arithmetic average values of the number of door openings calculated by time intervals, and performing a defrosting operation during the period that the refrigerator is not used by the user, based on the arithmetic average value information. The overall steps are also periodically repeated after the lapse of predetermined days so that a variation in refrigerator using pattern by the user can be learned, so as to control the defrosting operation based on the variation.
