[0003] Existing water purifier systems usually include the following basic components: booster pump, filter module, solenoid valve, heating tank, hot water pump and faucet.

[0047] Specifically, the water inlet module 10 is mainly responsible for receiving and providing raw water, and is the starting point of the entire water purification system. The design of the water inlet module 10 must ensure that the raw water can be stably supplied to the filter module 20.

[0048] The filter module 20 is connected to the water inlet module 10 and the control module 30 respectively, and is used to filter the raw water flowing out of the water inlet module 10 to obtain purified water and then flow out to the control module 30;

[0049] Specifically, the filter module 20 is composed of a filter unit 22 and at least one booster pump 21. The booster pump 21 receives raw water from the water inlet module 10 and provides sufficient pressure to push the water flow through the filter unit 22 to remove impurities and harmful substances and produce clean water.

[0050] The control module 30 is connected to the filter module 20 and the water outlet module 40, respectively, and is used to control the flow direction and flow rate of the purified water flowing out of the filter module 20, and to control the temperature of the purified water flowing out to be the target temperature;

[0051] Specifically, the control module 30 is responsible for controlling the flow direction, flow rate and temperature of the purified water. The control module 30 may specifically include a plurality of control units, which can adjust the mixing ratio of hot water and cold water, as well as the heating or cooling process according to the user's settings, to ensure that the outlet water temperature reaches the target temperature set by the user; and control the flow direction and flow rate of the purified water, for example, whether the purified water flows out of the cold water pipe or the hot water pipe at the set flow rate.

[0055] Optionally, in some embodiments, the filtration module 20 may specifically include a filtration unit 22 and at least one booster pump 21;

[0056] The input end of the booster pump 21 is connected to the output end of the water inlet module 10, and the output end of the booster pump 21 is connected to the input end of the filter unit 22. The booster pump 21 is used to provide the filter unit 22 with the water pressure required for filtration;

[0057] The output end of the filter unit 22 is connected to the input end of the control module 30 , and is used to filter the raw water flowing out of the water inlet module 10 , and then flow the purified water obtained after filtration to the control module 30 .

[0058] Specifically, Figure 2 As shown, the filtration module 20 in this embodiment can specifically include a filtration unit 22 and at least one booster pump 21, which ensures that the raw water can obtain sufficient pressure before entering the filtration unit 22 to achieve an efficient filtration process. The input end of the booster pump 21 is connected to the output end of the water inlet module 10, and its output end is connected to the input end of the filtration unit 22. The core function of the booster pump 21 is to provide the necessary water pressure for the filtration unit 22, ensuring that the raw water can flow through the filter material at an appropriate pressure, thereby effectively removing impurities in the water. The output end of the filtration unit 22 is connected to the input end of the control module 30, which is responsible for filtering the pressurized water provided by the booster pump 21. The filtered clean water will flow into the control module 30 to prepare for subsequent temperature control and distribution.

In addition, the speed of the booster pump can be intelligently adjusted according to the actual water demand and the feedback of the filter module, further improving the response speed and control accuracy of the system.

[0068] The output end of the hot water pump 33 is connected to the first input end of the water outlet module 40, and is used to flow the clean water in the heating water tank to the water outlet module 40 and adjust the hot water outlet flow rate.

[0069] Optionally, in some embodiments, the first control unit may further include a hot water temperature sensor 34, which is disposed in the heating water tank and is used to monitor the hot water temperature of the heating water tank in real time.

[0070] Specifically, Figure 2As shown, the first control unit in this embodiment may specifically include a first solenoid valve 31, a heating water tank, a hot water pump 33 and a hot water temperature sensor 34, wherein the first solenoid valve 31 is responsible for controlling the flow rate and time of clean water entering the heating water tank, ensuring that the heating water tank can be replenished with water in a timely manner according to demand; connected to the output end of the first solenoid valve 31, the heating water tank is responsible for storing and heating clean water, which is not only used to provide storage space for hot water, but also heats the water through a built-in heating element to reach a set temperature; the hot water pump 33 is connected to the output end of the heating water tank, and the hot water pump 33 is responsible for extracting water heated to an appropriate temperature from the heating water tank, and controlling the outlet flow rate of the hot water by adjusting its rotation speed to meet the usage requirements of different users; the hot water temperature sensor 34 is installed in the heating water tank, and is used to monitor and feedback the temperature of the hot water in real time, which is crucial to ensuring the accuracy of the outlet water temperature.

[0074] Optionally, in some embodiments, the second control unit further includes a cold water temperature sensor 37 , which is disposed between the filter module 20 and the regulating valve 35 and is used to monitor the cold water temperature from the filter module 20 to the water outlet module 40 in real time.

[0075] Specifically, Figure 2As shown, the second control unit in this embodiment may specifically include a regulating valve 35, a flow meter 36 and a cold water temperature sensor 37. The regulating valve 35, as a part of the second control unit, is responsible for regulating the cold water outlet flow rate from the filter module 20 to the water outlet module 40. The regulating valve 35 can adjust the opening of the valve plate according to the user's setting or the automatic control of the system, thereby controlling the flow rate of the cold water; the flow meter 36 is connected to the output end of the regulating valve 35, and the flow meter 36 is responsible for real-time monitoring of the cold water outlet flow rate from the filter module 20 to the water outlet module 40, wherein the data of the flow meter 36 can be fed back to the control system for adjusting and optimizing the entire water outlet temperature control process.

This sensor is crucial to ensure the temperature accuracy of the cold water before mixing, and is used to provide instant temperature feedback so that the system can make corresponding adjustments.

[0076] In this embodiment, the flow rate of cold water can be adjusted as needed by setting a regulating valve to ensure the accuracy of the cold water flow before mixing with hot water; real-time flow data is provided by setting a flow meter, so that the system can be dynamically adjusted according to these data to meet the user's precise water outlet temperature requirements; by accurately controlling the flow rate and temperature of cold water, the system can avoid unnecessary energy waste and improve overall energy efficiency; users can set the outlet water temperature according to personal needs, and the system can quickly respond and provide water of the required temperature according to the actual flow rate and temperature of cold water and hot water, thereby improving the convenience and comfort of use; users only need to set the required temperature, and the system can automatically adjust the mixing ratio of cold water and hot water; by intelligently controlling the regulating valve and flow meter, the noise generated during the operation of the equipment can be reduced while meeting the use requirements; through intelligent control, the equipment is prevented from running at high intensity for a long time, which helps to extend the service life of the regulating valve and flow meter; the temperature and flow rate of cold water are accurately controlled to prevent discomfort caused by inappropriate water temperature.

[0079] Specifically, Figure 3As shown, the control module 30 in this embodiment may further include a third control unit, which is a further innovation of the outlet water temperature control device and involves the reflux treatment of excess purified water. In order to solve the problem of increased pressure buildup noise caused by excessive water production from the filter module 20, in addition to reducing the noise by reducing the speed of the booster pump 21, Figure 3 As shown, the present embodiment adds a third control unit, including a second solenoid valve 38 and a check valve 39. When the filter module 20 produces too much water, the second solenoid valve 38 opens, and the excess purified water returns to the water inlet end. This not only avoids the noise caused by excessive water pressure before the flow regulating valve 35, but also reduces the filtering pressure of the filter module 20 after the purified water returns to the water inlet end, which is beneficial to extending the service life of the filter module 20.

[0080] In a specific embodiment, the third control unit includes a second solenoid valve 38 and a check valve 39, which work together to achieve reflux control of the clean water. The input end of the second solenoid valve 38 is connected to the output end of the filter module 20, and its output end is connected to the input end of the check valve 39. When the water production rate of the filter module 20 exceeds the water outlet flow rate of the water outlet module 40, the second solenoid valve 38 will open to allow excess clean water to flow back. The output end of the check valve 39 is connected to the input end of the booster pump 21 in the filter module 20 to ensure that the clean water can only flow in one direction and avoid the backflow of clean water to damage the booster pump 21. The third control unit can intelligently control the opening and closing of the second solenoid valve 38 according to the real-time working state of the system, thereby adjusting the reflux of the clean water and maintaining the stable operation of the system.

[0081] This embodiment avoids the noise caused by excessive water pressure before the flow regulating valve by controlling the backflow of excess clean water, thereby improving the user experience; the use of the check valve prevents the potential damage of the booster pump to the backflow of clean water, ensuring the long-term stable operation of the system; the working pressure of the filter module and the booster pump is reduced, which helps to extend the service life of these key components; by intelligently controlling the backflow of clean water, unnecessary energy waste is avoided and the energy efficiency of the system is improved; the intelligent control of the system reduces noise and equipment wear, providing users with a quieter and more reliable use environment; the design of the third control unit enables the water outlet temperature control device to adapt to different water demand and water pressure conditions, with good adaptability and flexibility; the flow direction and backflow of clean water are accurately controlled to avoid safety hazards caused by excessive system pressure.

[0082] In a specific embodiment, the outlet water temperature control device provided in this embodiment comprises a booster pump, a filter module, a first solenoid valve, a flow regulating valve, a heating water tank, a hot water pump, a faucet, a flow meter, a cold water temperature sensor, a heating water tank temperature sensor and a plurality of pipelines.

The outlet of the heating water tank passes through the hot water pump to pump the water in the tank to the faucet to flow out. The cold water temperature sensor is installed in the cold water pipeline, and the heating water tank temperature sensor is installed in the heating water tank. The booster pump provides the filter module with the water pressure required for filtration, and the speed of the booster pump is adjusted to adjust the water flow rate of the filter module.

[0085] See also Figure 4 , Figure 4The flow chart of the outlet water temperature control method provided in this embodiment is as follows. The outlet water temperature control method is used in the outlet water temperature control device described in any of the above embodiments. The specific contents of the outlet water temperature control device can be referred to above and will not be described here.

[0086] like Figure 4 As shown, the outlet water temperature control method provided in the embodiment of the present application includes the following steps:

[0087] S1. Filter the raw water flowing out of the water inlet module through the filter module to obtain purified water and then flow it out to the control module;

[0088] Specifically, for step S1, the first step is to use the filter module to filter the raw water provided by the water inlet module. This step ensures the quality and safety of the purified water and lays the foundation for subsequent temperature control.

[0089] S2, controlling the flow direction and flow rate of the purified water flowing out of the filtration module through the control module, and controlling the temperature of the purified water to be the target temperature;

[0090] Specifically, in step S2, the filtered clean water flows into the control module, which is responsible for controlling the flow direction and temperature of the clean water, including controlling the supply of hot water and cold water respectively through the first control unit and the second control unit according to the target temperature set by the user.

[0091] S3, providing purified water reaching the target temperature through the water outlet module;

[0092] Specifically, for step S3, the control module uses the data collected by the hot water temperature sensor and the cold water temperature sensor to intelligently adjust the hot water pump and the regulating valve to achieve precise temperature control, including calculating and adjusting the flow rates of hot water and cold water according to the specific heat capacity formula and the principle of conservation of energy transfer to achieve the desired mixing temperature.

[0093] The outlet water temperature control method also includes intelligent control processes, such as automatic water replenishment, heating, temperature monitoring and adjustment, to ensure the accuracy and stability of the outlet water temperature.

[0094] In a specific embodiment, the water outlet temperature control method provided in this embodiment has the following specific implementation process: the booster pump starts, the filter module works, the first solenoid valve opens to replenish water for the heating water tank, and the booster pump stops after the water is filled, the filter module stops working, and the first solenoid valve is closed; the heating water tank starts heating, and the water temperature is detected in real time by the heating water tank temperature sensor. When the water temperature in the tank is heated to the set temperature TH, the heating is stopped; when the user needs to use hot water with a temperature of TH, the hot water pump starts, and hot water with a temperature of TH flows out from the faucet; when the user needs to use cold water, the booster pump starts, the filter module works, the flow regulating valve opens, and cold water flows directly out from the faucet.

[0095] In addition, when the cold water flow rate required for the system to output water is low, the system reduces the speed of the booster pump and reduces the water production flow rate of the filter module, which can reduce working noise.

[0096] In summary, the outlet water temperature control method provided in the embodiment of the present application is to filter the raw water flowing out of the water inlet module through the filter module, obtain purified water and then flow it out to the control module; control the flow direction and flow rate of the purified water flowing out of the filter module through the control module, and control the temperature of the purified water to the target temperature; and provide purified water reaching the target temperature through the water outlet module. The embodiment of the present application can accurately control the water temperature in the heating water tank and the outlet water temperature when mixing cold water and hot water, ensuring that users can set and obtain warm water of a specific temperature according to personal needs, greatly improving the flexibility and convenience of use; at the same time, by accurately controlling the temperature and flow rate of hot water, the risk of scalding caused by excessively high water temperature or excessively fast water flow is reduced, and the safety of use is improved.
