Water purifier

A water purifier, comprising:

• a purified water supply unit for supplying purified water produced by filtering raw water;
• a hot water generation unit for generating hot water by heating the purified water supplied from the purified water supply unit;
• a hot water discharge unit for discharging the hot water generated by the hot water generation unit to an outside of the water purifier;
• and
• a control unit which receives a set temperature and a set water discharge quantity of the hot water as input and controls the purified water supply unit, the hot water generation unit, and the hot water discharge unit such that the hot water is discharged at the set temperature in the set water discharge quantity,
• wherein the hot water generation unit comprises a storage member for storing the purified water and a heater for heating the purified water stored in the storage member, and
• the control unit operates the heater when the hot water is being discharged to the outside by the hot water discharge unit, and stops the heater according to a predetermined criterion before the water discharge quantity of the hot water reaches the set water discharge quantity and the water discharging is terminated,
• wherein the control unit stops the heater when a remaining water discharge quantity of the hot water remaining until reaching the water discharge quantity or a remaining water discharge time of the hot water remaining until reaching the water discharge quantity is less than or equal to a predetermined reference value.
