Water purifier that dispenses purified water and hot water through one flow path

A water purifier that ejects hot water and purified non-heated water comprising:

• a housing;
• a filter provided inside the housing to purify water;
• a nozzle positioned outside of the housing, the nozzle configured to eject hot water and to eject purified non-heated water;
• a hot water module forming a heating flow path through which the purified non-heated water passes, the hot water module configured to heat the purified non-heated water so as to become hot water;
• a first valve configured to adjust a flow rate of water flowing to the hot water module;
• a hot water flow path coupled between the hot water module and the nozzle;
• a second valve installed on the hot water flow path, and configured to control flow of the hot water and flow of the purified non-heated water;
• and
• a controller configured to control operation of the hot water module, the first valve, and the second valve,
• wherein when the purified non-heated water is to be ejected from the nozzle, the controller is configured to:
• control a heating source of the hot water module to be off,
• control the first valve to be open so the purified non-heated water flows to the hot water module,
• control the second valve to be open so the purified non-heated water flows through the hot water flow path and the second valve to be ejected from the nozzle,
• wherein when the hot water is to be ejected from the nozzle, the controller is configured to:
• control the first valve to be open so the purified non-heated water flows to the hot water module,
• control the heating source of the hot water module to be on so the purified non-heated water is heated to become hot water,
• control the second valve to be open so the hot water flows through the hot water flow path and the second valve in order to be ejected from the nozzle,
• wherein the controller is configured to adjust an opening degree of the first valve based on the hot water to be ejected from the nozzle or the purified non-heated water to be ejected from the nozzle, and
• wherein, when the hot water is to be ejected from the nozzle, the opening degree of the first valve is adjusted to be smaller than when the purified non-heated water is to be ejected from the nozzle, wherein hot water is to pass through at least a portion of the hot water flow path and the second valve and is to be ejected from the nozzle, and the purified non-heated water is to be ejected from the nozzle after passing through the hot water flow path and the second valve without having a separate purified water flow path and a separate water purification valve, and
• the purified non-heated water is introduced into the hot water flow path when hot water is to be ejected from the nozzle, and the purified non-heated water is introduced into the hot water flow path without having a separate purified water flow path and a separate water purification valve when the purified non-heated water is to pass through the heating flow path of the heating module and the second valve, and is to be ejected from the nozzle.
