Claim 0:
1. A refrigerator comprising:
a storage chamber;
a cooler configured to supply cold into the storage chamber;
a first tray having a first portion of a cell;
a second tray 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 at least one of the first tray or the second tray such that, in an ice making process in which the liquid in the space is phase-changed into ice, the first portion of the first tray contacts the second portion of the second tray to form the space of the cell, and in an ice separation process in which the ice is removed from the space of the cell, the first portion of the first tray is spaced from the second portion of the second tray;
a heater provided adjacent to at least one of the first tray or the second tray;
a bracket on which at least one of the liquid supply or the driver is mounted;
a pusher having a first edge formed with a surface for pressing the second tray to separate the ice from the cell in the ice separation process, a bar extending from the first edge, and a second edge located an end of the bar; and
a controller configured to operate the heater while the ice is being formed so that gas bubbles dissolved in the liquid within the cell move from a portion of space where the liquid that has phase-changed into the ice to another portion of the space where the liquid is in a fluid state,
wherein the pusher is mounted on the bracket, and
wherein the second tray includes a first surface that defines the second portion and a second surface extending from the first surface, and a portion of the second surface is in contact with a third surface of first tray when the ice is forming in the space.
