Water purifier

A water purifier comprising:

• a water outlet unit for discharging water to an outside;
• a water temperature sensor for measuring a temperature of water discharged from the water outlet unit;
• a filter for filtering raw water to provide purified water;
• a cold water module for cooling the purified water to provide cold water;
• a hot water module including a heater for heating the purified water to provide hot water, and a hot water body providing a space which receives the hot water heated to a temperature higher than a temperature of cold water by the heater or through which the hot water flows;
• a flow channel connected to the water outlet unit, the filter, the cold water module, and the hot water module to provide a passage through which the purified water, the cold water, the hot water, and discharge water that is a mixture of the cold water and the hot water flow;
• a valve module including one or more valves that are selectively opened/closed to control the flow of the cold water, the hot water, and the discharge water in the flow channel;
• and
• a controller for controlling the valve module such that a temperature of the water discharged from the water outlet unit measured by the water temperature sensor is a target temperature,
• wherein the heater is disposed in a lower portion of the hot water body, and
• wherein the flow channel includes:
• a hot water discharge passage connected to the hot water body at the same height position as the heater or at a lower height position than the heater to provide a passage through which the hot water near the heater flows;
• and
• a mixed hot water supply passage connected to the hot water body above the heater and providing a passage through which the hot water above the heater flows to provide the hot water to be mixed in the discharge water.
