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: Provided is a refrigerator. The refrigerator may include a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The one tray assembly of the first and second tray assemblies may include a first portion that defines at least a portion of the ice making cell and a second portion extending from a predetermined point of the first portion.

Abstract: A refrigerator according to the present invention includes a storage chamber configured to store food, a cold air supply part configured to supply cold air to the storage chamber, a tray configured to form an ice making cell being a space in which water is phase-changed into ice by the cold air, a temperature sensor configured to sense the temperature of water or ice in the ice making cell, a heater configured to provide heat to the tray, and a controller configured to control the heater, in which the controller controls the heater to be turned on so that ice can be easily separated from the tray when the ice making is completed, and the controller controls the heater to be turned off when a temperature sensed by the temperature sensor reaches a first turn-off reference temperature greater than zero after a first reference time elapses in a state in which the heater is turned on.

Abstract: The present invention relates to a refrigerator.
The refrigerator of the present invention includes a first tray assembly configured to define one portion of an ice making cell, a second tray assembly configured to define the other 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 include a pusher including a first edge having a surface pressing the ice or at least one of the first and second tray assemblies to easily 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; and a pusher link having a connection part connected to the pusher. The controller controls to move at least one of the pusher and the second tray assembly and to change a relative position between the pusher and the second tray assembly.
