PURPOSE: An improved hot water function for a water dispenser using phase change material is provided to uniformly maintain the temperature of hot water in a hot water tank by using a method in which a phase change material(PCM) covers around the hot water tank. CONSTITUTION: An improved hot water function for a water dispenser using phase change material comprises a hot water tank(1), a heating wire(2), a PCM(3), a water tank(4), and a cold water tank. The hot wire supplies electricity to the hot water tank. The PCM covers the hot water tank so that not only an inner wall of the hot water tank but also the hot wire can be covered. |
