When the water outlet of the heat exchange device is selected to be boiled water (90-100 ℃), the first reversing valve 82 is switched to be communicated with the main water outlet 51, the first water suction pump 91 starts to work, and water is sucked from the second water tank 3 and then flows to the main water outlet 51 through the first reversing valve 82, and the water in the second water tank 3 is boiled water, so that large-flow boiled water outlet can be realized; when the selected outlet water is high-temperature-grade cool boiled water (such as 85 ℃), the first reversing valve 82 is switched to be communicated with the heat exchange tube 2, the second valve port of the proportional control valve 61 is opened, the first valve port is closed, the first water suction pump 91 starts to work, pumps water from the second water tank 3, flows to the heat exchange inlet 21 through the first reversing valve 82, exchanges heat with normal-temperature water in the first water tank 1 in the heat exchange tube 2, and then flows to the main water outlet 51 through the second heat exchange outlet 23 and the second valve port of the proportional control valve 61 in sequence; when the water is selected to be low-temperature cool boiled water (such as 45 ℃), the first reversing valve 82 is still communicated with the heat exchange tube 2, the proportion adjusting valve 61 is opened when the first valve port is opened, and closed when the second valve port is closed, the first water suction pump 91 starts to work, pumps water from the second water tank 3, flows to the heat exchange tube 2 through the first reversing valve 82, exchanges heat with normal-temperature water in the first water tank 1 in the heat exchange tube 2, and then flows to the main water outlet 51 through the first heat exchange outlet 22 and the first valve port of the proportion adjusting valve 61 in sequence; when the outlet water is selected to be the middle temperature range cool boiled water (for example, 50 ℃ to 80 ℃), the first reversing valve 82 is communicated with the heat exchange tube 2, the first valve port and the second valve port of the proportional control valve 61 are both opened, the first water suction pump 91 starts to work, pumps water from the second water tank 3 and flows to the heat exchange tube 2 through the first reversing valve 82, the water in the heat exchange tube 2 exchanges heat with the normal temperature water in the first water tank 1 and then flows to the first valve port and the second valve port of the proportional control valve 61 from the first heat exchange outlet 22 and the second heat exchange outlet 23 respectively, the first valve port and the second valve port simultaneously discharge water to the main water outlet 51, and when the actual outlet water temperature does not accord with the outlet water temperature selected by a user, the proportion of the warm boiled water entering the first valve port and the second valve port is adjusted by adjusting the opening degree of the first valve port and the second valve port of the proportional control valve 61 to achieve the purpose of adjusting the outlet water temperature, so that the actual outlet water temperature accords with the outlet water temperature selected by the user. After the water taking, the water inlet electromagnetic valve 81 can be opened to replenish water to the first water tank 1, the normal temperature water in the first water tank 1 is heated to hot water after heat exchange, and the cold water replenished from the first inlet 11 extrudes the hot water obtained after the heat exchange of the first water tank 1 from the first outlet 12 and replenishes the hot water into the second water tank 3.
