Title:

REFRIGERATOR AND METHOD FOR CONTROLLING SAME

Document Type and Number:

WIPO Patent Application WO/2020/071741

Kind Code:

A1

Abstract:

A refrigerator according to the present invention comprises: a storage compartment for storing food; a first temperature sensor for sensing the temperature in the storage compartment; a door for opening and closing the storage compartment; a cold air supply means for supplying cold air into the storage compartment; trays forming ice-making cells which are spaces in which water changes phase into ice due to the cold air; a second temperature sensor for sensing the temperature of the water or ice in the ice-making cells; a heater for supplying heat to the trays; and a control unit for controlling the heater, wherein, after opening or closing of the door is sensed during the ice-making process, the control unit increases the cooling power of the cold air supply means if an increase in cooling power therefrom is determined to be needed on the basis of the temperature sensed by the first temperature sensor, and decreases the amount of heat applied by the heater if a reduction in heat applied by the heater is determined to be needed on the basis of the change in temperature sensed by the second temperature sensor.
