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.

Abstract: The refrigerator of the present invention comprises: a storage compartment where food is stored; a cold air supply means for supplying cold air to the storage compartment; a first tray forming a part of an ice making cell which is a space where water phase-changes into ice by the cold air; a second tray which forms another part of the ice making cell and which can be brought into contact with the first tray during an ice making process, and which is connected to a driving unit so as to be spaced apart from the first tray during an ice separating process; a heater positioned adjacent to at least one of the first tray and the second tray; an ice bin for storing ice dropped from the ice making cell; a full ice level sensing means for sensing a full ice level of the ice bin; and a control unit for controlling the heater and the driving unit.
When the full ice level of the ice bin is sensed by the full ice level sensing means, the control unit controls the driving unit such that the second tray moves to the ice separating position after the ice making is completed.-
