1. A refrigerator comprising:
a cabinet comprising a refrigerating compartment and a freezing compartment; a refrigerating compartment door configured to open and close at least a portion of the refrigerating compartment; a dispenser disposed at the refrigerating compartment door and configured to dispense ice pieces; an ice bank that is disposed at the refrigerating compartment door, that defines an insulation space for storing the ice pieces, and that is configured to supply the ice pieces to the dispenser; an ice maker disposed in the freezing compartment and configured to make the ice pieces; a transfer device disposed in the freezing compartment and configured to transfer the ice pieces made by the ice maker to the ice bank; an ice chute that connects the transfer device to the ice bank and that is configured to guide the ice pieces transferred by the transfer device to the ice bank, the ice chute including:
a first chute extending from the transfer device; anda second chute connected to an end of the first chute and extending along a wall of the refrigerating compartment; and a discharge member provided inside the second chute and configured to move up and down to lift ice pieces in the second chute toward the ice bank, wherein the ice maker comprises:
an upper tray having a plurality of first recess parts, each having a hemispherical shape;a lower tray rotatably coupled to the upper tray, a rotational axis of the lower tray being disposed at a first side edge of the lower tray, the lower tray having a plurality of second recess parts, each having a shape corresponding to that of each of the first recess parts;a rotating arm of which a first end is coupled to the lower tray, wherein the rotational axis of the lower tray passes through the first end of the rotating arm and is perpendicular to the rotating arm;an elastic member connecting a second end of the rotating arm and the lower tray, the second end of the rotating arm being opposite of the first end of the rotating arm,wherein a first end of the elastic member is coupled to the second end of the rotating arm and a second end of the elastic member is coupled to a mounting part located at a second side edge of the lower tray, wherein the second side edge of the lower tray is perpendicular to the first side edge of the lower tray, and the mounting part is a predetermined distance away from the rotational axis of the lower tray; anda motor assembly of which a rotating shaft passes through the first end of the rotating arm to rotate the rotating arm,wherein, based on the rotating shaft of the motor assembly rotating in a first direction, the rotating arm integrally rotates with the rotating shaft of the motor assembly in the first direction to expand the elastic member, and the lower tray is rotated by a restoring force of the elastic member in the first direction to be attached to a lower surface of the upper tray, andwherein, based on the rotating shaft of the motor assembly rotating in a second direction which is opposite to the first direction, the rotating arm integrally rotates with the rotating shaft of the motor assembly in the second direction, and the lower tray is rotated in the second direction to be separated from the upper tray. |
