Abstract: Provided is a refrigerator. The refrigerator includes: a storage chamber configured to store food; a cooler configured to supply cold into the storage chamber; a first tray assembly configured to define a portion of an ice making cell that is a space in which water is phase-changed into ice by the cold; a second tray assembly configured to define another portion of the ice making cell, the second tray assembly being connected to a driver to contact the first tray assembly in an ice making process and to be spaced apart from the first tray assembly in an ice separation process; a heater disposed adjacent to at least one of the first tray assembly or the second tray assembly; and a controller configured to control the heater and the driver. The controller controls the heater to be turned on in at least partial section while the cooler supplies the cold so that bubbles dissolved in the water within the ice making cell moves from a portion, at which the ice is made, toward the water that is in a liquid state to make transparent ice.

Abstract: A refrigerator includes: 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; a heater for supplying heat to the tray; and a controller for controlling the heater. 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.

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.
