Abstract

The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of an ice making cell; a second tray assembly forming another part of the ice making cell; a heater disposed adjacent to at least one of the first and second tray assemblies; a driving unit connected to the second tray assembly; and a control unit for controlling the heater and the driving unit. The control unit controls to: supply water after the second tray assembly is allowed to move in the reverse direction to a water supply position upon completion of ice transfer; and turn on the heater so as to allow ice to be easily separated from the tray assemblies before the second tray assembly moves in the forward direction to a position of the ice transfer. The driving unit includes a cam capable of being connected to the second tray assembly, and a path in which a lever moves is formed inside the cam.

Description

technical field [0001] This instruction manual refers to refrigerators. Background technique [0002] In general, a refrigerator is a home appliance capable of storing food at a low temperature in an internal storage space shielded by a door. The refrigerator cools the inside of the storage space by using cold air, and can preserve the stored food in a refrigerated or frozen state. Generally, an ice maker for making ice is provided in the refrigerator. The ice maker accommodates water supplied from a water supply source or a water tank behind a tray, and generates ice by cooling the water. Moreover, the ice maker can remove the ice that has been made from the ice tray by heating or twisting. The ice maker that automatically supplies water and removes ice as described above is formed so as to open upward to hold molded ice. The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side, such as a crescent shape or a cube shape. ...
