REFRIGERATOR AND METHOD FOR CONTROLLING SAME

WIPO Patent Application WO/2020/071740

A1

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.
