Abstract: A refrigerator may include a cabinet, a door, and an ice maker. The ice maker may include a first tray; a first tray case; a second tray; and a second tray case. After supply of water to the ice-making cell while the second tray is at a water supply position, the second tray is to move in a first direction to an ice-making position. After generation of the ice while the second tray is at the ice-making position, the second tray is to move in a second direction so as to draw the ice out of the ice-making cell, and then the second tray is to move in the first direction to the water supply position. At the water supply position, the second tray is spaced from a portion of the first tray, and the first tray case includes a water overflow prevention wall configured to surround part of the first tray by being spaced apart from the first tray when the second tray is disposed at the water supply position.

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.
