Abstract: A refrigerator may include: a storage chamber, a first ice-maker, a second ice-maker, a cooler for supplying the cold to the storage chamber and the ice-making chamber, an ice bin for storing ice generated by the second ice-maker, a water supply unit for supplying water to the ice-making cell, a heater for supplying heat to the ice-making cell, and a controller for controlling the heater. The controller may increase the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.

Abstract: A refrigerator according to the present invention may comprise a first tray assembly forming one part of ice-making cells, and a second tray assembly forming the other part of same. Any one tray assembly, from among the first and second tray assemblies, comprises a first part forming at least a part of the ice-making cells, and a second part extending from a set point on the first part so as to reduce water supplied to the ice-making cells from leaking through a space between the first and second tray assemblies.

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.
