A water dispenser including a heat-exchanger (10), a heater (20), a water-storage tank (30), and a faucet (40) is provided mainly. The heat-exchanger (10) has a first/second guiding-channel (C1, C2), a first inlet/outlet (12, 14) communicated with two ends of the first guiding-channel (c1), and a second inlet/outlet (16, 18) communicated with two ends of the second guiding-channel (C2). The water flows into the heat-exchanger (10) through the first inlet (12), and flows out of the heat-exchanger (10) through the first outlet (14). Two ends of the heater (20) are communicated with the first outlet (14) and the second inlet (16), and the water flowed out of the first outlet (14) is heated by the heater (20). The heated water flows into the heat-exchanger (10) through the second inlet (16), and flows out of the heat-exchanger (10) through the second outlet (18). The water-storage tank (30) is used to store the water flowed out of the second outlet (18). The faucet (40) is communicated with the water-storage tank (30) and the heater (20) respectively. |
