Abstract

A refrigerator according to the present invention comprises: a storage chamber in which food is stored; a cold air supply means for supplying cold air to the storage chamber; a tray forming an ice-making cell as a space in which water undergoes a phase change to ice by means of the cold air; a heater for supplying heat to the tray; and a controller for controlling the heater. The controller starts ice-making after water supplied to the ice-making cell by a first amount of water supply is completed. The controller turns on the heater in at least a part of a range in which the cold air supply means supplies cold air such that air bubbles dissolved in water inside the ice-making cell can move from ice-generating parts to liquid-state water, thereby generating transparent ice. The controller determines whether or not the heater is functioning abnormally in the ice-making process. If it is determined that the heater is functioning abnormally, the controller supplies water to the ice-making cell by a second amount of water supply, which is smaller than the first amount of water supply, during the next water supply process.

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. 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.

[0003] The ice maker can remove ice after ice making from the ice tray by heating or twisting.

[0004] The ice maker, which automatically supplies water and removes ice, is formed to open upward to hold molded ice.

[0005] The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side, such as a crescent shape or a c...
