Abstract: A refrigerator includes a first tray assembly to define one portion of an ice making cell, a second tray assembly to define another portion of the ice making cell, a heater disposed adjacent to at least one of the first or second tray assemblies, and a controller configured to control the heater. The refrigerator further includes 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 at least one of the pusher or the second tray assembly to move and to change a relative position between the pusher and the second tray assembly.

Abstract: A refrigerator according to the present invention comprises: a storage space in which food is stored; a cooler for supplying cold to the storage space; a first tray assembly constituting a part of an icing cell which is the space in which water is phase-changed to ice by the cold; a second tray assembly constituting another part of the icing cell; a heater located to be adjacent to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater, wherein the control unit performs controls so that the heater is turned on in at least a partial period while the cooler supplies the cold, and thus air bubbles disintegrating in the water inside the icing cell move to liquid-phase water from a part where ice is generated, thereby enabling transparent ice to be generated, and the degree of cold transfer, which is the amount of cold of the cooler is to be transferred, is different in the first tray assembly and the second tray assembly.
