Abstract
An artificial intelligence (AI) refrigerator includes an evaporator, a freezing chamber, an ice-making unit, a cold air duct that connects the freezing chamber to the ice-making unit, a discharge unit that discharges ice, and a controller. The controller is configured to generate ice extraction information that includes an extraction time at which a user has extracted ice, and an amount of ice extracted at the extraction time, determine an ice extraction pattern based on ice extractions captured in the ice extraction information, based on the ice extraction pattern, generate an ice-making pattern that includes one or more ice-making start times and an ice-making amount corresponding to each ice-making start time, and based on the ice-making amount, adjust an amount of cold air introduced from the freezing chamber to the ice-making unit through the cold air duct to accelerate or decelerate an ice-making speed corresponding to each ice-making start time.
