Abstract: A refrigerator includes a first tray assembly defining one 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 to control the heater. The refrigerator further includes a pusher including a first edge having a surface pressing at least one of the ice or the first and second tray assemblies to separate the ice from the tray assemblies, a bar extending from the first edge, a second edge disposed at the end of the bar, and a guide connection part. 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. The refrigerator further includes a guide slot providing a movement path of the guide connection part.

Abstract: Provided is a refrigerator in which a heater disposed at a side of a first tray or a second tray may be turned on in at least partial section while a cold air supply part supplies cold air to an ice making cell so that bubbles dissolved in water within the ice making cell move from a portion at which ice is made toward liquid water to make transparent ice, and one or more of the cooling power of the cold air supply part and the heating amount of heater may be controlled according to a mass per unit height of the water in the ice making cell so that the transparency is uniform for each unit height of the water in the ice making cell.

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.
