Abstract: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.

Abstract: A refrigerator includes: a storage chamber configured to store food; a cooler configured to supply cold into the storage chamber; a tray defining an ice making cell, which is a space in which water is phase-changed into ice by the cold; a water supply part configured to supply the water into the ice making cell; a temperature sensor configured to sense a temperature of the water or the ice within the ice making cell; a heater configured to supply heat into the ice making cell; and a controller configured to control the heater. 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. The controller variably controls the heating amount of the heater so that a rate at which the water inside the ice making cell is made into ice during an ice making process is maintained within a predetermined range that is lower than an ice making rate when ice making is performed while the heater is turned off. When a defrosting start condition is satisfied in the ice making process, the controller performs a defrosting process and reduces the amount of cold supply of the cooler.

Abstract: A refrigerator comprises: a storage compartment for storing food; a first temperature sensor; a door; a cold air supply means; trays forming ice-making cells; a second temperature sensor; a heater for supplying heat to the trays; and a control unit, 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 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 includes a first tray assembly defining a portion of an ice making cell, a second tray assembly defining another portion of the ice making cell, a heater disposed adjacent to at least one of the first and second tray assemblies, and a controller configured to control the heater. The refrigerator further includes a pusher having a first edge pressing the ice or at least one of the first and second tray assemblies to separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at the end of the bar. The second tray assembly includes a first coupling part connected to the pusher and a second coupling part connected to the driver. The controller moves at least one of the pusher and the second tray assembly to change a relative position between the pusher and the second tray assembly.
