In addition, the fourth valve (V4) is provided in the flow path connecting the cold water tank 124 and the extraction unit 160, and opens and closes under the control of the control unit 150 to control cold water extraction through the extraction unit 160. can do.

The ice-making water tank 126 stores the cold water supplied from the cold water tank 124 as ice-making water, and the stored ice-making water is supplied to the auger module 132 and used to make ice.

The ice tank 128 stores ice generated by the auger module 132 , and the stored ice may be extracted through the extraction unit 160 . To this end, a transfer unit (not shown) for transporting ice may be provided inside the ice tank 128 , and the ice transported by the transfer unit may be extracted through the extraction unit 160 . Here, the conveying means may be implemented in various ways known to those skilled in the art, such as, for example, a feeder screw and a motor driving the feeder screw.
