20 Claims

1. An ice maker comprising:

a first tray configured to form a first cell;

a second tray configured to form a second cell, the first and second cells configured to form a space in which liquid is phase-changed into ice;

a driver configured to move the second tray relative to the first tray; and

a controller configured to control the driver during an ice making process and during an ice separation process,

wherein one ice making cycle comprises the ice making process and the ice separation process, and after the one ice making cycle is completed, a next ice making cycle is performed,

wherein in the one ice making cycle, after a liquid supply process is completed and while the ice making process is performing, the controller controls the driver to move the second tray from a first position to a second position that is different from the first position, and

wherein in the one ice making cycle, before the ice separation process starts and while the ice making process is performing, the controller controls the driver to return the second tray to the first position.
