ARTIFICIAL INTELLIGENT REFRIGERATOR AND SYSTEM AND METHOD FOR CONTROLLING TEMPERATURE THEREOF

Abstract

Disclosed is an artificial intelligent refrigerator including a cold-storage chamber; a temperature information receiver for receiving external temperature information of a location in which a purchased item is located; an arrival time information receiver for receiving expected arrival time information to be taken until the item is stored in the cold-storage chamber; and a temperature controller for setting in advance a target cooling temperature of the cold-storage chamber for the item based on an artificial intelligence (AI) processor in which a neural network model is mounted before the item is stored in the cold-storage chamber. Here, the temperature controller inputs the external temperature information and the expected arrival time information to the neural network model to estimate a temperature change of the item and sets in advance a target cooling temperature of the cold-storage chamber based on an estimated temperature change of the item.
