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: A refrigerator includes a storage chamber, a cold air supply which supplies cold air to the storage chamber, a first tray which forms a part of an ice making cell that is a space where water is phase-changed into ice by the cold air, a second tray which forms another part of the ice making cell and which may come into contact with the first tray during an ice making process and may be separated from the first tray during an ice transfer process, a heater adjacent to at least one of the first tray or the second tray, a sensor which determines the position of the second tray in a movement process of the second tray, and a control unit which controls the heater.

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.
