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.

Abstract: A refrigerator of the present invention comprises: a storage chamber for storing food; a cool air supplying means for supplying cool air to the storage chamber; a first tray which forms a part of an ice-making cell in which water is phase-changed to ice by the cool air; a second tray which forms another part of the ice-making cell and can be in contact with the first tray during an ice-making process; a water supply valve for adjusting a flow of the water supplied to the ice-making cell; a water supply amount detector for detecting the amount of water supplied to the ice-making cell; and a controller for controlling the water supply valve. The controller controls the water supply valve to supply water to the ice-making cell as much as a first reference water supply amount, for supplying water to the ice-making cell at a water supply position of the second tray. After finishing the water supply as much as the first reference water supply amount, the controller moves the second tray to an ice-making position and determines whether the water supply amount of the ice-making cell has reached a target water supply amount by using the water supply amount detector. When the water supply amount of the ice making cell has reached the target water supply amount, the controller starts ice-making, and when the water supply amount of the ice making cell has not reached the target water supply amount, the controller moves the second tray back to the water supply position and controls the water supply valve to supply water as much as a second reference water supply amount which is less than the first reference water supply amount.

Abstract: A refrigerator includes a storage chamber, a cooler configured to supply cold, a tray defining an ice making cell, a liquid supply configured to supply liquid, a temperature sensor, a heater configured to supply heat, and a controller configured to control the heater. The controller controls the heater to be turned on during ice making to make transparent ice. The controller variably controls a heating amount of the heater so that an ice making rate is maintained within a predetermined range. When a defrosting start condition is satisfied in the ice making process, the controller performs a defrosting process.
