Refrigerator

A refrigerator comprising:

• a storage chamber;
• a cooler configured to supply cold into the storage chamber;
• 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 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 liquid supply, 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 when the liquid is supplied to the cell,
• wherein the controller controls the driver to move the second tray assembly in a reverse direction after moving to an ice separation position in a forward direction so as to remove the ice from the first tray assembly and the second assembly when the liquid in the cell has phase-changed into the ice,
• wherein the controller controls driver and the liquid supply so that the liquid is supplied to the cell after the second tray assembly moves to a water supply position in the reverse direction after the ice is separated from the first tray assembly and the second tray assembly, 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 second tray assembly includes a first coupling region connected 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.
