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 includes a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The refrigerator includes a pusher provided with a first edge on which a surface configured to press one or more of the first and second tray assemblies is disposed to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at an end of the bar. At least one of the pusher or the second tray assembly moves so as to change a relative position between the pusher and the second tray assembly.

Abstract: Provided is a refrigerator in which a heater disposed at a side of a first tray or a second tray may be turned on in at least partial section while a cold air supply part supplies cold air to an ice making cell so that bubbles dissolved in water within the ice making cell move from a portion at which ice is made toward liquid water to make transparent ice, and one or more of the cooling power of the cold air supply part and the heating amount of heater may be controlled according to a mass per unit height of the water in the ice making cell so that the transparency is uniform for each unit height of the water in the ice making cell.

Abstract: The present invention relates to a refrigerator. The refrigerator of the present invention may include a first tray assembly configured to define one portion of an ice making cell, a second tray assembly configured to define the other portion of the ice making cell, and a heater disposed adjacent to at least one of the first and second tray assemblies, and a controller configured to control the heater. The controller controls the heater to be turned on so that ice is easily separated from the tray assemblies before the second tray assembly moves to the ice separation position in a forward direction.

Abstract: The refrigerator of the present invention comprises: a storage compartment where food is stored; a cold air supply means for supplying cold air to the storage compartment; a first tray forming a part of an ice making cell which is a space where water phase-changes into ice by the cold air; a second tray which forms another part of the ice making cell and which can be brought into contact with the first tray during an ice making process, and which is connected to a driving unit so as to be spaced apart from the first tray during an ice separating process; a heater positioned adjacent to at least one of the first tray and the second tray; an ice bin for storing ice dropped from the ice making cell; a full ice level sensing means for sensing a full ice level of the ice bin; and a control unit for controlling the heater and the driving unit.
When the full ice level of the ice bin is sensed by the full ice level sensing means, the control unit controls the driving unit such that the second tray moves to the ice separating position after the ice making is completed.-

Abstract: A refrigerator includes a first tray forming a part of an ice-making cell in which water undergoes a phase change to ice due to the cool air, a second tray forming another part of the ice-making cell and in contact with the first tray during an ice-making process, a water supply to supply water to the ice-making cell, a heater which is adjacent to at least one of the first tray or the second tray; and a controller to control the heater. The second tray is moveable with respect to the first tray, and the controller is configured to control a movement of the second tray.

Abstract: A refrigerator may include: a first tray forming a part of ice-making cells; a second tray forming the other part of the ice-making cells; a heater for supplying heat to the ice making cells; a cooler for supplying cold to a storage compartment; and a control unit for controlling the heater and the cooler. The operation modes of the refrigerator include a first mode and a second mode. The control unit may control so that either or both of the amounts of cooling by the cooler and the amount of heating by the heater vary in the first mode and the second mode.
