Abstract: A refrigerator of the present disclosure can include an ice making cell, a heater configured to supply heat to the ice making cell during an ice making process, and a controller configured to control the heater. The process for controlling the heater includes a basic heating process and an additional heating process that is performed after the basic heating process. In the basic heating process, the controller performs control so that a heating amount of the heater varies according to a mass per unit height of water in the ice making cell. In at least partial section of the additional heating process, the controller controls the heater to operate with a heating amount that is equal to or less than a heating amount of the heater in the basic heating process.

Abstract: A refrigerator may include: a storage chamber, a first ice-maker, a second ice-maker, a cooler for supplying the cold to the storage chamber and the ice-making chamber, an ice bin for storing ice generated by the second ice-maker, a water supply unit for supplying water to the ice-making cell, a heater for supplying heat to the ice-making cell, and a controller for controlling the heater. The controller may increase the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.

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.

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.
