Abstract: A refrigerator includes an ice tray, a motor, an ejector including a rotary shaft and a protrusion pin, and a heater for selectively supplying heat to the ice tray. A control method of the refrigerator includes a first step of sensing whether the ejector is rotated to reach a first setup position; a second step of driving the heater and stopping driving of an ice making compartment fan if the first step is satisfied; a third step of determining whether the ejector is rotated to reach a second setup position; and a fourth step of stopping driving of the heater if the third step is satisfied, and wherein the ejector continues to be rotated while the second to fourth steps are implemented.

Abstract: An ice maker includes an ice tray configured to receive water, where the ice tray includes a plurality of partition ribs that partition an inner space of the ice tray into a plurality of cells, an ejector that is configured to rotate relative to the ice tray, that is configured to cause rotation of ice pieces in a rotation direction relative to the ice tray, and that is configured to discharge the ice pieces from the ice tray, and a motor configured to drive the ejector to rotate in a first direction and a second direction opposite to the first direction. The ice tray further includes a protrusion portion that is located at each cell, that protrudes from a lower surface of each cell, and that extends along the lower surface of each cell in a direction corresponding to the rotation direction of the ice pieces relative to the ice tray.

Abstract: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.
