Abstract: An ice maker includes an ice tray, a motor configured to rotate with respect to the ice tray, an ejector configured to cause rotation of an ice piece, the ejector including a rotary shaft and a protrusion pin, a heater configured to selectively supply heat to the ice tray, and a first sensor unit configured to detect a rotation angle of the protrusion pin about an axis of the rotary shaft. The first sensor unit is further configured to, before discharge of the ice piece from the ice tray, detect whether the protrusion pin has rotated by a predetermined angle about the axis of the rotary shaft, and the heater is further configured to be turned off based on the first sensor unit detecting that the protrusion pin has rotated by the predetermined angle.

Abstract: A refrigerator according to the present invention comprises: a storage space in which food is stored; a cooler for supplying cold to the storage space; a first tray assembly constituting a part of an icing cell which is the space in which water is phase-changed to ice by the cold; a second tray assembly constituting another part of the icing cell; a heater located to be adjacent to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater, wherein the control unit performs controls so that the heater is turned on in at least a partial period while the cooler supplies the cold, and thus air bubbles disintegrating in the water inside the icing cell move to liquid-phase water from a part where ice is generated, thereby enabling transparent ice to be generated, and the degree of cold transfer, which is the amount of cold of the cooler is to be transferred, is different in the first tray assembly and the second tray assembly.
