[0027] Based on the problem pointed out in the background technology that the existing water dispenser takes a long time to modulate warm boiled water and the water output is not good. The present invention provides a warm boiled water making system that adds a water storage container between the heat exchanger and the heating element to store warm water within a set temperature range, so as to shorten the water heating time and increase the water output, improving the user experience.

[0028] Specifically, as Figure 1 and Figure 3As shown in the figure, the cooled boiled water making system of the present invention includes a first water storage container 1, a heat exchanger 3, a second water storage container 4, a heating element 5, a water pump 2, and a water outlet end. Among them, the heat exchanger 3 includes a cold water inlet, a cold water outlet, a hot water inlet, and a warm water outlet. The cold water inlet of the heat exchanger 3 is communicated with the first water storage container 1, the warm water outlet of the heat exchanger 3 is communicated with the water outlet end, the inlet of the second water storage container 4 is communicated with the cold water outlet of the heat exchanger 3, the inlet of the heating element 5 is communicated with the outlet of the second water storage container 4, and the outlet of the heating element 5 is respectively communicated with the hot water inlet of the heat exchanger 3 and the water outlet end; the water pump 2 is located between the first water storage container 1 and the cold water inlet of the heat exchanger 3 or between the cold water outlet of the heat exchanger 3 and the inlet of the second water storage container 4 or between the outlet of the second water storage container 4 and the inlet of the heating element 5, and the outlet of the heating element 5 and / or the warm water outlet of the heat exchanger 3 is communicated with the inlet of the second water storage container 4, or the outlet of the heating element 5 and / or the warm water outlet of the heat exchanger 3 is communicated with the cold water inlet of the heat exchanger 3.

[0029] It can be understood that with the help of the water pump 2, the hot water heated by the heating element 5 or the warm water after heat exchange can be directly refluxed into the second water storage container 4 for storage and standby. Or, the hot water heated by the heating element 5 or the warm water after heat exchange can also be refluxed into the second water storage container 4 for storage and standby through the flow channel between the cold water inlet and the cold water outlet of the heat exchanger 3. When the user draws water, the warm water within the set temperature range stored in the second water storage container 4 can be heated to the boiling state for a short time by the heating element 5 to output hot water, or the hot water can be heat exchanged to output cooled boiled water at a higher temperature. The warm water within the set temperature range stored in the second water storage container 4 can also be directly output, or the warm water can be heat exchanged to form cooled boiled water at a lower temperature. At the same time, when the warm water in the second water storage container 4 is heated by the heating element 5 for a short time or directly output, it is necessary to correspondingly increase the output power of the water pump 2 to increase the water output per unit time.

[0030] Therefore, for the above cooled boiled water making system, the waiting time for the user to draw water is short, and the temperature distribution range of the cooled boiled water after heat exchange and temperature adjustment is large, meeting the user's demand for a large amount of cooled boiled water at different temperatures and improving the user experience.

[0047] In addition, the first water storage container 1 is selected as a water tank capable of storing purified water, and the second water storage container 4 is selected as a water storage tank with a heat preservation function to save energy consumption.

[0048] Embodiment III

[0049] As Figure 3 shown, the cool boiled water making system of this embodiment includes a first water storage container 1, a heat exchanger 3, a second water storage container 4, a heating element 5, a water pump 2, and a faucet 8 (i.e., the water outlet end) that are connected in sequence. Among them, the water pump 2 is located between the inlet of the second water storage container 4 and the inlet of the heating element 5.

[0050] More specifically, as Figure 3 shown, the first water storage container 1 is connected to the cold water inlet of the heat exchanger 3, the cold water outlet of the heat exchanger 3 is connected to the inlet of the second water storage container 4, the outlet of the second water storage container 4 is connected to the inlet of the water pump 2, the outlet of the water pump 2 is connected to the inlet of the heating element 5, the outlet of the heating element 5 is respectively connected to the hot water inlet of the heat exchanger 3 and the faucet 8, and the warm water outlet of the heat exchanger 3 is connected to the faucet 8. Among them, a control valve 11 is provided on the pipeline between the first water storage container 1 and the cold water inlet of the heat exchanger 3.

[0051] As Figure 3 shown, the cool boiled water making system of this embodiment includes a regulating valve 6 and a reversing valve 7. The regulating valve 6 has two inlets and one outlet, and the reversing valve 7 has one inlet and two outlets. Among them, one inlet of the regulating valve 6 is connected to the outlet of the heating element 5, the other inlet of the regulating valve 6 is connected to the warm water outlet of the heat exchanger 3, the outlet of the regulating valve 6 is connected to the inlet of the reversing valve 7, one outlet of the reversing valve 7 is connected to the faucet 8, and the other outlet of the reversing valve 7 is connected to the inlet of the second water storage container 4.

[0052] As Figure 3 shown, a one-way check valve 9 is provided on the pipeline between the other outlet of the reversing valve 7 of the cool boiled water making system of this embodiment and the cold water outlet of the heat exchanger 3, and this one-way check valve 9 prevents the water from the cold water outlet of the heat exchanger 3 from directly flowing to the reversing valve 7.

[0053] As Figure 3 shown, a first temperature sensor 41 for detecting the water temperature in the second water storage container 4 is provided in the second water storage container 4 of the cool boiled water making system of this embodiment, a second temperature sensor 51 and a third temperature sensor 52 are respectively provided at the inlet and outlet of the heating element 5, and a fourth temperature sensor 81 for displaying the water outlet temperature is provided between one outlet of the regulating valve 6 and the faucet 8.

[0054] When the first temperature sensor 41 detects that the water temperature in the second water storage container 4 is lower than the set temperature range, another outlet of the reversing valve 7 is conducted with the inlet of the water pump 2, the control valve 11 is closed, and the heating element 5 and the water pump 2 are started, so that the heated hot water or the warm water after heat exchange directly flows back into the second water storage container 4 through the regulating valve 6 and the reversing valve 7, thereby ensuring that the water temperature in the second water storage container 4 is kept constant within the set range for the user to draw water for use.

[0055] In addition, the first water storage container 1 is selected as a water tank capable of storing purified water, and the second water storage container 4 is selected as a water storage tank with a heat preservation function to save energy consumption.

[0056] It can be understood that in the above three embodiments, during the initialization process of the cooled boiled water making system, the water pump 2 and the heating element 5 are started, and by controlling the opening degree of the regulating valve 6, only the hot water boiled by the heating element 5 can be refluxed into the second water outlet container, or the warm water after the hot water is heat-exchanged by the heat exchanger 3 can be refluxed into the second water outlet container, so that the water temperature in the second water outlet container is kept within the set temperature range for the user to draw water.

[0057] The water drawing mode of the initialized cooled boiled water making system is as follows:

[0058] When the user draws hot water, the reversing valve 7 is conducted with the faucet 8, and by controlling the opening degree of the regulating valve 6, only the hot water flows through the regulating valve 6 and the reversing valve 7 and is output to the faucet 8. When the water temperature required by the user for drawing water is the same as the water temperature in the second water outlet container, the reversing valve 7 is conducted with the faucet 8, the water pump 2 is started, and by controlling the opening degree of the regulating valve 6, only the warm water in the second water outlet container flows through the regulating valve 6 and the reversing valve 7 and is output to the faucet 8.

[0059] When the water temperature required by the user for drawing water is lower than the water temperature in the second water outlet container, the reversing valve 7 is conducted with the faucet 8, only the water pump 2 is started, and by controlling the opening degree of the regulating valve 6, the water output from the second water outlet container is mixed with the water output from the heat exchanger 3 to adjust and output cooled boiled water with a temperature lower than that of the second water outlet container to the faucet 8.

[0060] When the water temperature required by the user for drawing water is higher than the water temperature in the second water outlet container, the reversing valve 7 is conducted with the faucet 8, the water pump 2 and the heating element 5 are started, and the hot water passing through the heat exchanger 3 is modulated to a water temperature higher than that of the second water outlet container by controlling the opening degree of the regulating valve 6, or the water output from the second water outlet container is directly heated to the set temperature and output directly.

[0061] Compared with the existing cooled boiled water making system, the above water drawing mode is flexible and efficient, shortening the user's water drawing waiting time and meeting the user's large water drawing demand.

[0062] It should be noted that the heat exchanger 3 of the present invention includes a hot water flow channel and a cold water flow channel that exchanges heat with the hot water flow channel. The hot water inlet and the warm water outlet of the heat exchanger 3 are respectively located at both ends of the hot water flow channel, and the cold water inlet and the cold water outlet of the heat exchanger 3 are respectively located at both ends of the cold water flow channel. Moreover, the present invention does not impose any restrictions on the specific structure of the above-mentioned heat exchanger 3. As long as the heat exchanger 3 can exchange heat and cool the water flowing through it, the heat exchanger 3 can adopt a spiral tube heat exchange structure, or the heat exchanger 3 can also adopt a plate stack heat exchange structure, etc. Such flexible adjustment and change of the specific heat exchange structure of the heat exchanger 3 do not deviate from the basic principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0063] In addition, it should be noted that the present invention does not impose any restrictions on the specific structure of the heating body 5. As long as the heating body 5 can heat and boil the water flowing through it, those skilled in the art can set the structure of the heating body 5 according to actual needs. For example, the heating body 5 can be set as a tubular shape with an electric heating wire, or the heating body 5 can also be set as an electromagnetic heating device, etc. Such flexible adjustment and change do not deviate from the basic principle and scope of the present invention and should all be limited within the protection scope of the present invention.

[0064] Finally, the present invention provides a water dispenser, which includes the above-mentioned cool boiled water making system.

[0065] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
