A control module (not drawn in the figure) can be provided to control whether water production is required. The technology of the control module is basically consistent with the existing technology and will not be elaborated here.

[0026] Furthermore, the heating water tank is also equipped with a drain pipe 38, and the second water outlet pipe is also equipped with a fifth one-way valve 19 that can control the drainage of the drain pipe. When the user drains the water, they need to press the fifth one-way valve 19 to allow atmospheric air to enter the hot water tank from the hot water tank outlet, so that the atmospheric pressure in the drain pipe and the second water outlet pipe offset each other, allowing the water in the hot water tank to be discharged smoothly. The second water outlet pipe located between the heating water tank and the fourth water channel is also connected to the exhaust pipe 39, which is equipped with an exhaust solenoid valve 26 and a sixth one-way valve 27. The heating water tank is also equipped with a water tank NTC and a heating element.

The water inlet end of the return water circuit is connected to the outlet pipe located between the seventh one-way valve and the TDS meter, and the water outlet end of the return water circuit is connected to the water inlet pipe located between the water inlet solenoid valve and the booster pump. The return water circuit is provided with a reflux solenoid valve 5 and an eighth one-way valve 3.

[0028] Preferably, it also includes a wastewater path 43, which can be connected to the wastewater port of the filter element. A wastewater solenoid valve 28 and a ninth one-way valve 29 are provided on the wastewater path. The ends of the wastewater path and the exhaust pipe can be connected, that is, at the rear ends of the corresponding sixth one-way valve and the ninth one-way valve.

[0029] The utility model also discloses another technical feature:

[0030] A water dispenser comprises the above-mentioned large-flow and temperature-adjustable water outlet system.

[0031] More specifically, the present invention can realize the functions of discharging cold water, hot water and mixed cold and hot water. Figure 1The system shown includes: a ball valve 1, a water inlet solenoid valve 2, an eighth one-way valve 3, a booster pump 4, a return solenoid valve 5, a filter element 6, a seventh one-way valve 7, a TDS meter 8, a first solenoid valve 9, a normal temperature water tank 10, a water pump 13, a first one-way valve 14, a faucet 15, a fourth one-way valve 16, a temperature sensor 17, a third one-way valve 18, a fifth one-way valve 19, a heating water tank 20, a second one-way valve 23, a regulating valve 24, a second solenoid valve 25, an exhaust solenoid valve 26, a sixth one-way valve 27, a wastewater solenoid valve 28, and a ninth one-way valve 29. The normal temperature water tank 10 also includes a high liquid level sensor 11 and a low liquid level sensor 12. The heating water tank 20 also includes a water tank NTC 21 and a heating element 22. The water outlet faucet is equipped with a human-machine interface, allowing users to control the control module through the interface, selecting cold water, hot water, or mixed cold and hot water at different temperatures for water outlet.

[0032] When the utility model is working: raw water enters the water inlet pipe, passes through the ball valve 1, the water inlet solenoid valve 2, is pressurized by the booster pump 4, and enters the filter element 6 for filtration. The generated waste water is discharged through the wastewater solenoid valve 28 and the ninth one-way valve 29. The filtered clean water passes through the TDS meter 8 and is divided into two water paths. The first water path is the cold water path and the second water path is the hot water path. The first water path passes through the first solenoid valve 9 and enters the normal temperature water tank 10 for storage. When the system receives a signal from the user to take cold water, the water pump 13 starts working to pump out the water in the cold water tank and provides it to the user through the faucet 15. When the water storage in the cold water tank is insufficient, the water inlet solenoid valve 2 and the first solenoid valve 9 are opened, the booster pump 4 works, the system starts to make pure water, and replenishes the normal temperature water tank of cold water. After the water is replenished to the high liquid level, the system stops making water, the booster pump 4 stops working, and the water inlet solenoid valve 2 and the first solenoid valve 9 are closed. After passing through the second solenoid valve 25 and the regulating valve 24, the second water path is divided into two water paths again, namely the third water path and the fourth water path. The cold water passes through the regulating valve and enters the heating water tank 20 along the third water path. The heating element 22 in the heating water tank heats the cold water and keeps it warm after reaching the set temperature. When the system receives a signal from the user to take hot water, the water inlet solenoid valve 2 and the second solenoid valve 25 open, the first solenoid valve 9 and the exhaust solenoid valve 26 close, the booster pump 4 starts, the regulating valve 24 opens, and the cold water enters the heating water tank, squeezing out the hot water stored in the heating water tank. The hot water flows out through the faucet 15 for the user to use. When the user needs mixed hot and cold water at different temperatures, the system automatically adjusts the regulating valve 24 to control the water output ratio of the third and fourth water paths. By mixing the water at different output ratios, water at different temperatures is achieved.

[0033] The system also features a heating tank overpressure protection device. When the heating tank is turned on, the exhaust solenoid valve 26 remains open to ensure that hot air in the heating tank is immediately discharged through the exhaust channel, preventing excessive pressure inside the tank. A sixth one-way valve 27 is located behind the exhaust solenoid valve 26 to prevent wastewater from flowing back through the pipeline.

[0034] In addition, the system is also provided with a manual drainage channel for the heating water tank. When the user needs to go out for a long time or does not use hot water for a long time for other reasons, the user can open the drain plug at the bottom of the heating water tank, and then press the fifth one-way valve 19 to drain the water in the heating water tank to avoid the internal water from deteriorating or breeding bacteria due to long-term non-use.

[0035] The present application further provides a water dispenser, including the water system described above. The water system of the present application is suitable for use on a water dispenser. Among them, a booster pump is used to increase the water delivery power of the raw water to the filter element, and under the action of the filter element, the raw water can be filtered, thereby outputting clean water. The output clean water can enter the normal temperature water tank for storage through the first water channel, or enter the heating water tank for heating and then storage. Among them, the clean water in the normal temperature water tank is pumped out by a water pump, and the water pump is preferably a large-flow pump specification, which can obtain a large flow of cold water output. The faucet is preferably a smart faucet, which can enhance the user interaction experience and improve the safety performance and operational performance of the water dispenser. It makes it easier and faster for users to get water.

[0036] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
