[0002] In existing drinking water equipment, the water circuit system plays an important role in filtering tap water and then heating it to meet different water temperature requirements. Most existing water circuit systems heat water using hot water tank heating and storage technology. Although the existing hot water tank heating and storage technology can provide a large flow of boiling or hot water, when different temperatures of hot water are needed, consumers need to wait for a period of time before the desired temperature is delivered, resulting in a poor consumer experience and room for improvement. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art and provide a water circuit system for a heated drinking water device. The system controls the flow rate of the first and second pumps through an electronic control module so that room temperature water flowing through the mixing module and hot water flowing through the hot water module are mixed in a predetermined ratio to quickly output water at different temperatures.

[0004] To achieve the above objectives, this utility model provides a water circuit system for a heated drinking water device, including an electronic control module, a filtration module, a room temperature water module, a hot water module, and a mixing module; The outlet of the filtration module is connected to the inlet of the ambient temperature water module, the inlet of the hot water module, and the inlet of the mixing module, respectively. The filtration module is used to purify the raw water into pure water and also includes a first pump body for pumping the pure water to the ambient temperature water module, the hot water module, and the mixing module. The ambient temperature water module includes a first solenoid valve and an ambient temperature water outlet connected in sequence via pipelines. The hot water module includes a second solenoid valve, a hot tank assembly, a second pump body, and a hot water outlet connected in sequence via pipelines.

The outlet of the mixing module is connected to the pipeline between the second pump body and the hot water outlet. The mixing module includes a third solenoid valve and a check valve connected in sequence through the pipeline. The electronic control module controls the working state of each solenoid valve to achieve the selection between different modules, and controls the pumping flow rate of the first pump body and the second pump body to achieve the mixing ratio between room temperature water and water in the hot tank assembly.

[0005] The hot tank assembly is further configured to include a water tank, a heating element disposed at the bottom of the water tank, and a water level switch and a first temperature sensing probe disposed inside the water tank.

[0006] The mixing module is further configured such that: the mixing module also includes a second temperature sensor for detecting the temperature of the incoming pure water; the hot water module also includes a third temperature sensor disposed between the hot water outlet and the second pump body for detecting the temperature of the mixed water; and the outlet of the mixing module is disposed between the third temperature sensor and the second pump body.

[0007] The filter module is further configured to include a device inlet, a pre-filter, a fourth solenoid valve, a first pump body, a reverse osmosis membrane filter, a flow meter assembly, and a post-filter, which are connected in sequence via pipelines.

[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0014] This utility model discloses a water circuit system for a heating type drinking water device, as follows: Figure 1 As shown, the system includes an electronic control module 50, a filter module 10, a room temperature water module 20, a hot water module 30, and a mixing module 40. The outlet of the filter module 10 is connected to the inlet of the room temperature water module 20, the inlet of the hot water module 30, and the inlet of the mixing module 40, respectively. The filter module 10 is used to purify raw water into pure water and also includes a first pump body 14 for pumping pure water to the room temperature water module 20, the hot water module 30, and the mixing module 40. The first pump body 14 is preferably a booster pump, so that the pressure of the booster pump is used to pump the incoming water. The room temperature water module 20 includes a control module 50, a filter module 10, a room temperature water module 20, a hot water module 30, and a mixing module 40. The hot water module 30 includes a first solenoid valve 21 and a room temperature water outlet 22 connected in sequence via pipelines. The hot water module 30 includes a second solenoid valve 31, a hot water tank assembly 32, a second pump body 33, and a hot water outlet 35 connected in sequence via pipelines. The second pump body 33 is preferably a micro pump and is used to control the water flow rate of the hot water module 30. The outlet of the mixing module 40 is connected to the pipeline between the second pump body 33 and the hot water outlet 35. The mixing module 40 includes a third solenoid valve 42 and a check valve 43 connected in sequence via pipelines. The electronic control module 50 controls the operating state of each solenoid valve to achieve communication between the modules. The selection of the filter module 10 and the ambient temperature water module 20 are controlled by adjusting the pumping flow rates of the first pump body 14 and the second pump body 33 to achieve the mixing ratio between ambient temperature water and the water in the hot water tank assembly 32. Specifically: when the electronic control module 50 controls the first solenoid valve 21 and the first pump body 14 to open and controls the second solenoid valve 31 and the third solenoid valve 42 to close, the filter module 10 and the ambient temperature water module 20 are connected, and ambient temperature water is output; when the electronic control module 50 controls the second solenoid valve 31, the first pump body 14 and the second pump body 33 to open and controls the first solenoid valve 21 and the third solenoid valve 42 to close, the filter module 10 and the hot water tank assembly 32 are connected. Module 30 is connected to the hot water prepared by the heating tank assembly 32. When the electronic control module 50 controls the second solenoid valve 31, the third solenoid valve 42, the first pump body 14 and the second pump body 33 to open and controls the first solenoid valve 21 to close, the filter module 10 is connected to the hot water module 30 and the mixing module 40, and water with a temperature lower than that of the hot water prepared by the heating tank assembly 32 but higher than that of room temperature water is output. That is, the pumping flow rate of the first pump body 14 and the second pump body 33 is controlled by the electronic control module 50 to control the mixing ratio of room temperature water and hot water. In other words, warm water of different temperature ranges can be output immediately by controlling the mixing ratio.

[0015] In this embodiment, as Figure 1 and Figure 2As shown, the hot water tank assembly 32 includes a water tank 321, a heating element 322 disposed at the bottom of the water tank 321, a water level switch 323 disposed inside the water tank 321, and a first temperature sensor 324. The mixing module 40 also includes a second temperature sensor 41 for detecting the temperature of the incoming pure water. The hot water module 30 also includes a third temperature sensor 34 disposed between the hot water outlet 35 and the second pump body 33 for detecting the temperature of the mixed water. The outlet of the mixing module 40 is disposed between the third temperature sensor 34 and the second pump body 33. Thus, the electronic control module 50 can accurately control the outlet water temperature through the feedback from the first to the third temperature sensor 34.

[0016] In this embodiment, as Figure 1 As shown, the filtration module 10 includes a device inlet 11, a pre-filter 12, a fourth solenoid valve 13, a first pump body 14, a reverse osmosis membrane filter 15, a flow meter assembly 16, and a post-filter 17, all connected sequentially via pipelines. The concentrate outlet of the reverse osmosis membrane filter 15 is connected to a proportional valve 151 and a discharge outlet 152 via pipelines for discharging concentrate. Thus, the ambient temperature water path is: device inlet 11 → pre-filter 12 → fourth solenoid valve 13 → first pump body 14 → reverse osmosis membrane filter 15 → flow meter assembly 16 → post-filter 17 → first solenoid valve 21 → ambient temperature water outlet 22; the hot water path is: device inlet 11 → pre-filter 12 → fourth solenoid valve 13 → fourth solenoid valve 14 → first pump body 14 → reverse osmosis membrane filter 15 → flow meter assembly 16 → post-filter 17 → first solenoid valve 21 → ambient temperature water outlet 22. Valve 13 → First pump body 14 → Reverse osmosis membrane filter element 15 → Flow meter assembly 16 → Post-filter element 17 → Second solenoid valve 31 → Hot tank assembly 32 → Second pump body 33 → Third temperature sensor 34 → Hot water outlet; Warm water outlet path: Equipment inlet 11 → Pre-filter element 12 → Fourth solenoid valve 13 → First pump body 14 → Reverse osmosis membrane filter element 15 → Flow meter assembly 16 → Post-filter element 17, Partial pure water (controlled by the second pump body 33) → Second solenoid valve 31 → Hot tank assembly 32 → Second pump body 33, Partial pure water → Second temperature sensor 41 → Third solenoid valve 42 → One-way valve 43, Warm water formed after mixing → Third temperature sensor 34 → Hot water outlet 35.

[0017] Compared with the prior art, this utility model has a simple and reasonable structure. Through the opening of different solenoid valves by the electronic control module, the water drinking device can immediately output room temperature water, hot water, or warm water. At the same time, by controlling the pumping flow of the first pump body and the second body, the mixing ratio between room temperature water and hot water can be adjusted to immediately output warm water of different temperature ranges, which greatly improves the consumer experience.

[0018] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
