Abstract

A control method and system of an ice making device as well as a refrigerator having the same. The control method includes receiving first detection data of a detection sensor on an ice-making water injection pipe after ice is turned over and before water is injected; judging whether ice exists in the ice-making water injection pipe according to the first detection data; and turning on a heating assembly when ice exists in the ice-making water injection pipe. In the control method of an ice making device according to the present invention, the detection sensor is provided, whether the water injection pipe is frozen is judged by the detection sensor detecting whether ice exists, the detection method is more accurate, a freezing state of the ice-making water injection pipe can be known more accurately, and the heating assembly can be turned on more efficiently to unfreeze the ice-making water injection pipe.
