1. A water purifier comprising:
a water tank having a cold water path inside the water tank;
a coolant inside the water tank;
a cooling device including an evaporator inside the water tank and through which a refrigerant flows, and a compressor that is operable to compress the refrigerant, the cooling device configured to cool the coolant so that the coolant cools water flowing through the cold water path;
a temperature sensor configured to detect a temperature of the coolant and output coolant temperature information about the detected temperature of the coolant;
an agitator that is operable to agitate the coolant; and
a controller configured to:
control the compressor and the agitator to operate simultaneously to cool the coolant, and
control the agitator to stop operating while the compressor is controlled to continue operating based on the coolant temperature information output by the temperature sensor indicating that the temperature of the coolant is lower than or equal to a preset ice-making temperature during the cooling of the coolant.
