Refrigerator and method for controlling same

Abstract

A refrigerator according to the present invention may comprise ice-making cells; a heater for supplying heat to the ice-making cells during the ice-making process; and a control unit for controlling the heater. The step for controlling the heater comprises a main heating step, and an additional heating step carried out following the main heating step, wherein in the main heating step, the control unit controls so that the heat applied by the heater is varied in accordance with the mass per unit height of water in the ice-making cells, and in at least a portion of the additional heating step, the control unit controls the heater so that same applies the same or less amount of heat as compared to the amount of heat applied thereby in the main heating step.

Description

technical field

[0001] This instruction relates to a refrigerator and a control method thereof. Background technique

[0002] In general, a refrigerator is a home appliance capable of storing food at a low temperature in an internal storage space shielded by a door.

[0003] The refrigerator cools the inside of the storage space by using cold air, and can preserve the stored food in a refrigerated or frozen state. Generally, an ice maker for making ice is provided in the refrigerator. The ice maker accommodates water supplied from a water supply source or a water tank behind a tray, and generates ice by cooling the water. In addition, the ice maker can remove the ice that has been made from the ice tray by heating or twisting. The ice maker that automatically supplies water and removes ice as described above is formed so as to open upward to hold molded ice.

[0004] The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side,...
