Classification: CPC F | IPC F

Claim 0:
1. A refrigerator comprising:
a storage chamber;
a cooler configured to supply cold into the storage chamber; and
an ice maker including:
a first tray assembly having a first portion of a cell;
a second tray assembly having a second portion of the cell, the first portion and the second portion being configured to define a space formed by the cell;
a tray supporter configured to support the second portion of the cell;
a liquid supply configured to supply a liquid to the space;
a driver that moves the second tray assembly relative to the first tray assembly such that the second portion of the second tray assembly contacts the first portion of the first tray assembly to form the space of the cell in an ice making process when the liquid in the space is phase-changed into ice, and that moves the second tray assembly relative to the first tray assembly such that the second portion of the second tray assembly is spaced from the first portion of the first tray assembly in an ice separation process to remove the ice from the first and second tray assemblies; and
a controller configured to control the cooler, the driver,

wherein the controller controls the cooler so the liquid in the space of the cell is phase-changed into the ice after the second tray assembly moves to an ice making position,
wherein the controller controls the driver to move the second tray assembly to an ice separation position so as to remove the ice from the first tray assembly and the second tray assembly when the liquid in the cell has phase-changed into the ice,
wherein the refrigerator further comprises a pusher including a first edge having a surface pressing at least one of the ice, the first tray assembly, or the second tray assembly to separate the ice from the first tray and the second tray assemblies, a bar extending from the first edge, and a second edge provided at an end of the bar,
wherein the tray supporter includes a first coupling region connected to a link coupled to the pusher and a second coupling region connected to the driver, and
wherein the controller is configured to operate the driver such that at least one of the pusher or the second tray assembly moves to change a position of the pusher relative to the second tray assembly.
