The arrangement can provide boiled water for users, so that water supply is healthier and safer.
It should be noted that, although the high temperature water tank 1 in the present embodiment maintains the water temperature and heats the water to boil by the heating element, this arrangement is not a limitation of the present utility model, and other arrangements may be adopted by those skilled in the art in other embodiments without departing from the principles of the present utility model, for example: the high-temperature water heated to boiling is directly input into the high-temperature water tank 1, and the high-temperature water tank 1 is provided with an insulation layer so as to insulate the high-temperature water.

Therefore, the water temperature of the low-temperature water may be lower than the water temperature of the high-temperature water in the high-temperature water tank 1 or not higher than the water temperature required by the user.
The heat exchange assembly 3 is used for carrying out heat exchange on the high-temperature water in the high-temperature water tank 1 and the low-temperature water in the low-temperature water tank 2. Specifically, the heat exchange assembly 3 includes a high temperature portion 31, a low temperature portion 32, and a water pump 33.
The high temperature portion 31 includes a first pipe. One end of the first pipe is communicated with the high-temperature water tank 1 so that high-temperature water in the high-temperature water tank 1 can enter the first pipe. The other end of the first pipe is communicated with the water outlet nozzle 5 so that water in the first pipe can be discharged through the water outlet nozzle 5. Further, a control valve 6 is provided upstream of the water outlet nozzle 5, and the control valve 6 can control the flow rate of water discharged from the water outlet nozzle 5. It will be appreciated by those skilled in the art that although the first conduit in this embodiment is in direct communication with the water spout 5, this is not a limitation of the present utility model, and that other arrangements may be employed in other embodiments by those skilled in the art without departing from the principles of the present utility model.

The first temperature detecting element 4 and the water pump 33 are electrically connected to a controller, and the controller controls the rotation speed of the water pump 33 according to the temperature of the heat exchanged high-temperature water acquired by the first temperature detecting element 4. The rotation speed of the water pump 33 can affect the flow rate or flow velocity of the low-temperature water in the low-temperature portion 32. When the flow rate of the low-temperature water in the low-temperature portion 32 increases, the heat exchange efficiency also increases so that the temperature of the high-temperature water outputted from the high-temperature portion 31 is lower. When the flow rate of the low-temperature water in the low-temperature portion 32 is slowed down, the heat exchange efficiency is also lowered so that the temperature of the high-temperature water outputted from the high-temperature portion 31 is higher. Therefore, after the actual water temperature of the water output from the high-temperature portion 31 is obtained by the first temperature detecting member 4, the rotation of the water pump 33 is adjusted according to the magnitude relation between the actual water temperature and the preset water temperature, so that the high-temperature portion 31 can output the water closer to the preset temperature.

The input is electrically connected to a controller which is capable of controlling the rotational speed of the water pump 33 according to a preset temperature set by a user to adjust the temperature of the output water.
The controller is configured to perform a control method of the water supply device, the controller may be configured to perform only the control method, and not perform other operation controls of the water purification system, which may be further equipped with other controllers; it may also be configured to perform other operation control of the water purification system in addition to the control method, i.e., the controller is an integrated execution module, i.e., each program in operation of the water purification system is executed.

S2, controlling the rotating speed of the water pump 33 according to the relation between the water temperature and the preset water temperature, so as to adjust the water temperature of the output water of the heat exchange assembly 3, and enable the water temperature of the output water to be closer to the preset temperature.
Referring to fig. 3, the specific steps of the control method are described in detail below:
and S101, enabling the high-temperature water in the high-temperature water tank 1 to flow into the first pipeline. And then S102 is performed.
S102, the water pump 33 drives the low-temperature water in the low-temperature water tank 2 to enter the second pipeline at a certain flow rate. After that, S103 is performed.
S103, heat exchange is carried out on the high-temperature water in the first pipeline and the low-temperature water in the second pipeline, so that the temperature of the high-temperature water in the first pipeline is reduced, and the high-temperature water is output from the first pipeline. After that, S104 is performed.
S104, the first temperature detecting piece 4 obtains the water temperature of the high-temperature water output by the first pipeline. And then S105 is performed.

If the water temperature of the high-temperature water output from the first pipe is lower than the preset water temperature, S107 is performed.
S106, driving the rotation speed of the water pump 33 to be increased so as to reduce the water temperature of the high-temperature water output by the first pipeline. After that, S104 is performed again.
And S107, driving the rotation speed of the water pump 33 to be reduced so as to increase the water temperature of the high-temperature water output by the first pipeline. After that, S104 is performed again.
To sum up, the temperature of the output water is obtained by the first temperature detecting element 4, the controller controls the rotation speed of the water pump 33 by the temperature of the output water, the rotation speed of the water pump 33 affects the flow speed of the low-temperature water in the low-temperature part 32 of the heat exchange assembly 3, and the flow speed affects the heat exchange efficiency in the heat exchange assembly 3, thereby affecting the water temperature of the output water. Therefore, by controlling the rotation speed of the water pump 33, the water temperature of the output water can be adjusted so that the water temperature of the output water is closer to the preset temperature, and the user requirement can be met.

This may result in an excessively high water temperature in the low-temperature water tank 2, thereby affecting the heat exchange efficiency. Therefore, when the temperature of the water in the low-temperature water tank 2 obtained by the second temperature detecting part is higher than the preset temperature, the user is reminded to replace the low-temperature water in the low-temperature water tank 2 or the device for automatically replacing the low-temperature water tank 2 is started so that the low-temperature water tank 2 can maintain a low temperature.
It should be noted that, although the outlet of the low temperature portion 32 is directly connected to the low temperature water tank 2 in the present embodiment, the arrangement is not limited to the present utility model, and other arrangements may be adopted by those skilled in the art in other embodiments without departing from the principles of the present utility model, for example: the outlet of the low temperature part 32 is connected to the outside of the water supply device so that the low temperature water after heat exchange is directly discharged and the low temperature water tank 2 is continuously replenished with low temperature water. Such an arrangement does not deviate from the basic principle of the utility model and therefore falls within the scope of the utility model.
