Ice maker and refrigerator including the same

A control method of a refrigerator, the refrigerator comprising an ice tray configured to receive water to generate ices, a motor configured to be rotated in a forward or reverse direction, an ejector configured to rotate the ices made in the ice tray to discharge the ices from the ice tray, the ejector being configured to be rotated by the motor, a heater configured to selectively supply heat to the ice tray, and an ice making compartment fan configured to supply cool air to the ice tray, comprising:

• a first step of sensing whether the ejector reaches a first setup position while being rotated;
• a second step of driving the heater and stopping driving of the ice making compartment fan based on the first step being 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 based on the third step being satisfied,
• wherein the control method further comprises a step of starting driving of the ice making compartment fan based on a predetermined time elapsing between the second step and the third step,
• wherein the ejector continues to be rotated while the second to fourth steps are implemented.

A control method of a refrigerator, the refrigerator including an ice tray configured to receive water to generate ices, a motor configured to be rotated in a forward or reverse direction, an ejector configured to rotate the ices made in the ice tray to discharge the ices from the ice tray, the ejector including (i) a cam that is configured to be rotated with the ejector by the motor and has a plurality of grooves defined at an outer circumferential surface of the cam and (ii) a rotating member in contact with the outer circumferential surface of the cam, a heater configured to selectively supply heat to the ice tray, a sensor configured to sense a position change of the rotating member based on the rotating member being hung each of the plurality of grooves of the cam, and an ice making compartment fan configured to supply cool air to the ice tray, the control method comprising:

• rotating the ejector by the motor;
• sensing, by the sensor, that the rotating member is hung in one of the plurality of grooves of the cam to thereby determine that the ejector reaches a first setup position while rotating the ejector by the motor;
• based on determining that the ejector reaches the first setup position, driving the heater and stopping driving of the ice making compartment fan while rotating the ejector by the motor;
• sensing, by the sensor, that the rotating member is hung in another one of the plurality of grooves of the cam to thereby determine that the ejector reaches a second setup position while rotating the ejector by the motor;
• and
• based on determining that the ejector reaches the second setup position, stopping driving of the heater while rotating the ejector by the motor.
