As shown in fig. 2, the heat exchange pipe is a spiral heat exchange pipe 3 disposed in the water storage tank 2, and the lower part of the spiral heat exchange pipe 3 is in contact with the bottom of the water storage tank 2. An inlet of the heating device 4 is connected to the water storage tank 2 through a first connection pipe 51, an outlet of the heating device 4 is connected to an upper end of the heat exchange pipe 3 through a second connection pipe 52, and a lower end of the heat exchange pipe 3 is connected to the water outlet 8 through a third connection pipe 53. The outlet of the heating device 4 is also connected to the water outlet 8 by a fourth connection tube 54. The third connection pipe 53 and the fourth connection pipe 54 are respectively provided with a first valve 71 and a second valve 72, and the opening degrees of the first valve 71 and the second valve 72 can be adjusted. The first connection pipe 51 is provided with a first water pump 61.

When a user inputs a command for supplying high-temperature boiling water through the control panel 11, the controller of the water dispenser controls the first water pump 61 to operate, and controls the first valve 71 and the second valve 72 to be in a closed state and an open state, respectively. Under the action of the first water pump 61, the water at normal temperature in the water storage tank 2 enters the heating device 4 through the first connection pipe 51, is boiled in the heating device 4, and flows to the water outlet 8 through the fourth connection pipe 54 to be discharged.

In the process, the high-temperature boiled water flowing into the heat exchange tube 3 exchanges heat with the normal-temperature water in the water storage tank 3, the high-temperature boiled water in the heat exchange tube 3 is cooled to be low-temperature boiled water, and the low-temperature boiled water flowing to the water outlet 8 is mixed with the high-temperature boiled water to form warm boiled water. The flow proportion of the third connecting pipe 53 and the fourth connecting pipe 54 is adjusted by adjusting the proportion of the opening degree of the first valve 71 and the opening degree of the second valve 72, so that the proportion of low-temperature boiled water and high-temperature boiled water flowing to the water outlet 8 can be adjusted, the temperature of the warm boiled water formed after mixing is further adjusted, and different requirements of users are met.

The lower part of the heat exchange tube 3 is contacted with the bottom of the water storage tank 2, no matter where the water level in the water storage tank 2 is, water in the water storage tank 2 is always contacted with the heat exchange tube 3, so that the heat exchange between the boiled water in the heat exchange tube 3 and the normal temperature water in the water storage tank 2 is realized, and the normal supply of warm boiled water by the water dispenser is ensured. The heat exchange tube 3 is spirally arranged, so that the heat exchange area can be increased, and the heat exchange efficiency is improved. Preferably, in order to further increase the heat exchange area, the heat exchange tube 3 may be configured as a first spiral heat exchange tube and a second spiral heat exchange tube connected in series, and the second spiral heat exchange tube is sleeved on the outer ring of the first spiral heat exchange tube. The opening degrees of the first valve 71 and the second valve 72 can be adjusted, and the temperature of the warm boiled water discharged from the water outlet 8 can be adjusted by adjusting the opening degrees of the first valve 71 and the second valve 72. It can be understood that one of the first valve 71 and the second valve 72 may be set to have an adjustable opening, and the ratio of the openings of the two valves is changed by adjusting the opening of the valve with the adjustable opening, so as to adjust the ratio of the low-temperature boiled water and the high-temperature boiled water flowing to the water outlet 8, and further adjust the temperature of the mixed warm boiled water.

In another possible embodiment, the first valve 71 and the second valve 72 may be arranged to be non-adjustable in opening degree. Thus, warm water can be supplied to the user in a state where the first valve 71 is open and the second valve 72 is closed; in a state where the first valve 71 is closed and the second valve 72 is opened, hot boiled water can be supplied to the user.
