Ice maker, refrigerator and control method of the same

Abstract

Provided are an ice maker, a refrigerator, and a method for controlling the same, which can accurately detect whether ice-making water in accommodated in an ice-making groove is full. To this end, an ice maker according to the present disclosure includes: a control box having a control unit disposed therein, an ice tray disposed on one side surface of the control box, and formed with an ice-making groove in which ice-making water is accommodated, a water supply unit configured to supply the ice-making water to the ice-making groove, and a detecting unit configured to detect the water level of the ice-making water accommodated in the ice-making groove, in which the detecting unit includes: a sensor housing formed of a non-conductor spaced apart from the ice tray and installed on one side surface of the control box, and having a water level measuring hole into which the ice-making water in the ice-making groove flows formed in one side surface thereof, a sensor formed of a conductor being in contact with the ice-making water flowing into the sensor housing through the water level measuring hole to detect the water level of the ice-making water, and a connector wire having one end connected to the sensor, and the other end connected to the control unit.
