A liquid dispenser which ejects hot liquid and purified liquid at an ambient temperature, the liquid dispenser comprising:

• a housing forming a storage space;
• a filter provided inside the housing to purify liquid supplied from an external liquid supply source;
• a liquid supply flow path configured to guide liquid supplied from the liquid supply source toward the filter;
• an auxiliary flow path configured to branch off at a first point of the liquid supply flow path and then to merge into a second point of the liquid supply flow path located downstream of the first point;
• a flow switching valve installed at the first point and configured to control a flow of liquid from the liquid supply flow path to the auxiliary flow path;
• a liquid ejection nozzle provided on the outside of the housing and through which liquid passing through the filter is ejected;
• a heating module included in a heating flow path through which purified liquid from the filter passes and configured to heat liquid passing along the heating flow path into hot liquid;
• a hot liquid flow path configured to guide hot liquid from the heating module toward the liquid ejection nozzle;
• a controller configured to control operation of the flow switching valve and the heating module, and
• an auxiliary heater configured to heat liquid flowing through the auxiliary flow path and installed in the auxiliary flow path.
