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.

An ice maker for a household refrigeration appliance is proposed, which comprises an ice making tray arranged to rotate about an axis of rotation and a drive unit for driving the ice making tray in rotation. The drive unit has an electric motor, the operation of which is controlled by a drive control system depending on the electric current consumption of the electric motor.

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.

An ice maker enables a refrigerator to recognize the operation of an ice separation heater when the ice maker operates the ice separation heater. A refrigerator can reduce or stop the power supplied to electronic components when an ice maker notifies the operation of an ice separation heater. The ice maker includes a tray for receiving liquid, an ejector for discharging ice frozen in the tray, a first heater for providing heat to the tray, and an ice maker control unit. When the heater operates, the ice maker enables a main control unit of the refrigerator to recognize the completion of ice making or the initiation of the operation of the heater.

An ice maker apparatus includes an ice mold having first and second ends spaced apart in a longitudinal direction of the ice mold via opposite, first and second lateral sides. A first recess is formed in the first lateral side of the ice mold. A first thermally insulative cover has a first depression formed therein and is removably attached to the ice mold and disposed adjacent to the first lateral side thereof. The first recess and the first depression collectively define a first passage therebetween. An ice maker evaporator is provided and has a first leg. The first leg is disposed within the first passage.

A refrigerator includes a storage chamber, a cold air supply which supplies cold air to the storage chamber, a first tray which forms a part of an ice making cell that is a space where water is phase-changed into ice by the cold air, a second tray which forms another part of the ice making cell and which may come into contact with the first tray during an ice making process and may be separated from the first tray during an ice transfer process, a heater adjacent to at least one of the first tray or the second tray, a sensor which determines the position of the second tray in a movement process of the second tray, and a control unit which controls the heater.

Proposed are an ice maker and a refrigerator including the ice maker. The ice maker includes a drive motor arranged inside a casing and configured to rotate an ice-making tray or an ejector pin, a gear set operating in unison with the drive motor, an in-unison operating lever provided to operate in unison with the gear set, a magnet being provided on one side of the in-unison operating lever, and a printed circuit board arranged to one side of the in-unison operating lever, a position detection sensor being provided on the printed circuit board in such a manner that an electric contact point is established according to trajectory followed by the moving magnet.

A refrigerator includes a storage chamber, a cold air supply which supplies cold air to the storage chamber, a first tray which forms a part of an ice making cell that is a space where water is phase-changed into ice by the cold air, a second tray which forms another part of the ice making cell and which may come into contact with the first tray during an ice making process and may be separated from the first tray during an ice transfer process, ; a heater adjacent to at least one of the first tray or the second tray, a sensor which determines the position of the second tray in a movement process of the second tray, and a control unit which controls the heater.
