[0002] A water purifier with integrated purification and heating functions is a type of water purifier that combines water purification and instant heating functions. It can not only effectively remove impurities, residual chlorine, heavy metals and other harmful substances from the water to ensure the safety and health of drinking water, but also heat the water instantly on the basis of purification to meet the diverse drinking water needs of families, thus providing convenience for users.

[0003] Currently, most integrated water purifier and heating systems rely on self-priming pumps to regulate water flow and achieve different levels of hot water output. However, self-priming pumps require the use of zero-pressure valves, which not only increases the complexity of the equipment but also occupies a relatively large space, hindering the compact and miniaturized design of the device.

The inlet end of the stepless regulating valve device is connected to the outlet end of the purification device, the outlet end of the stepless regulating valve device is connected to the inlet end of the heating device, and the outlet end of the heating device is connected to the water outlet assembly.

The outlet of the first purification component is connected to the inlet of the second purification component. The outlet of the second purification component is connected to the inlet of the third purification component. The outlet of the third purification component serves as the outlet of the purification device.

[0011] In one embodiment, the stepless regulating valve device includes a stepless regulating valve and a drive motor. The inlet of the stepless regulating valve is connected to the outlet of the purification device, and the outlet of the stepless regulating valve is connected to the inlet of the heating device. The stepless regulating valve is mechanically connected to the drive motor.

[0012] In one embodiment, the water system of the water purifier further includes a pressure switch, which is disposed between the water outlet of the purification device and the water inlet of the stepless regulating valve device.

[0018] The water pressure detection module is used to detect water pressure and output water pressure parameters to the controller;

[0019] The controller is also used to control the stepless regulating valve to close when the water pressure parameter is greater than a preset threshold.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] In one embodiment, a water circuit system for a water purifier is provided. For example... Figure 1 As shown, the water system of the water purifier includes a purification device 100, a stepless regulating valve device 200, a heating device 300, and a water outlet assembly 400. The inlet end of the stepless regulating valve device 200 is connected to the outlet end of the purification device 100, the outlet end of the stepless regulating valve device 200 is connected to the inlet end of the heating device 300, and the outlet end of the heating device 300 is connected to the water outlet assembly 400.

[0029] It is understandable that, in practical implementation, the water system of a water purifier also includes an inlet component, which is used to connect to an external water supply. Specifically, in scenarios where the raw water pressure provided by the external water supply is stable, the inlet end of the purification device 100 can be directly connected to the inlet component of the water purifier's water system. In scenarios where the water source pressure is unstable, the water system of the water purifier may also include a pressure reducing valve. The inlet end of the purification device 100 is connected to the outlet end of the pressure reducing valve, and the inlet end of the pressure reducing valve is connected to the inlet component. This allows the pressure reducing valve to regulate the inlet water pressure, ensuring that all components of the water purifier operate within a suitable pressure range.

[0030] Specifically, the purification device 100 is used to purify the raw water supplied from the external water supply to obtain purified water. A stepless regulating valve 200 is installed before the heating device 300; adjusting its valve opening regulates the water flow into the heating device 300. The heating device 300 heats the incoming purified water and outputs the heated water through the water outlet assembly 400. It can be understood that when the user needs room temperature water, the heating device 300 can be turned off, and the water output through the water outlet assembly 400 will then be room temperature water.

[0031] The structure of the water outlet assembly 400 can be configured according to actual conditions, for example, including a water outlet nozzle, with the heating device 300 connected to the water outlet nozzle. The stepless regulating valve device 200 is a device including a stepless regulating valve. In one embodiment, such as... Figure 2 As shown, the stepless regulating valve device 200 includes a stepless regulating valve 210 and a drive motor 220 that are mechanically connected. The inlet end of the stepless regulating valve 210 is connected to the outlet end of the purification device 100, and the outlet end of the stepless regulating valve 210 is connected to the inlet end of the heating device 300.

[0032] The stepless regulating valve 210 is a valve capable of continuously and steplessly adjusting the opening of the water flow channel. The drive motor 220 is used to drive the valve core of the stepless regulating valve 210 to move, thereby changing the valve opening. The mechanical connection between the stepless regulating valve 210 and the drive motor 220 results in a smaller overall size and less space required compared to the structure of a self-priming pump that requires a zero-pressure valve. In practical applications, a stepless regulating valve device integrating the stepless regulating valve 210 and the drive motor 220 can be used, resulting in a more compact overall structure and significantly reduced space occupation.

[0033] The water system of the aforementioned water purifier includes a purification device 100, a stepless regulating valve device 200, a heating device 300, and a water outlet assembly 400. The inlet of the stepless regulating valve device 200 is connected to the outlet of the purification device 100, the outlet of the stepless regulating valve device 200 is connected to the inlet of the heating device 300, and the outlet of the heating device 300 is connected to the water outlet assembly 400. By using the stepless regulating valve device 200 to regulate the water flow into the heating device 300, and because the stepless regulating valve device 200 is smaller in size than the combination of a self-priming pump and a zero-pressure valve, the required space is reduced, thereby improving the space utilization rate within the water purifier and facilitating the miniaturization and portability of the water purifier.

[0034] Furthermore, compared to the traditional combination of a self-priming pump and a zero-pressure valve, the stepless regulating valve 210 offers higher operational stability and resistance to external interference. Therefore, the stable operation of the stepless regulating valve 210 improves the continuity and reliability of hot water output, reduces the failure rate of the water purifier's water system, and enhances the overall reliability of the water purifier.

[0035] In one embodiment, such as Figure 3 As shown, the water outlet of the stepless regulating valve device 200 includes a first water outlet A and a second water outlet B; the heating device 300 includes a heating module 310 and a room temperature water control switch 320. The water inlet of the heating module 310 is connected to the first water outlet A, and the water inlet of the room temperature water control switch 320 is connected to the second water outlet B. Both the water outlets of the heating module 310 and the room temperature water control switch 320 are connected to the water outlet assembly 400; the second water outlet B is also connected to the purification device 100.

[0036] In this embodiment, the raw water first enters the purification device 100 for purification. The purified water is then divided into two streams by the stepless regulating valve device 200. One stream enters the heating module 310 through the first outlet A for heating, and the heated water flows to the water outlet assembly 400 as hot water output. The other stream flows through the second outlet B, passes through the ambient temperature water control switch 320, and flows to the water outlet assembly 400 as ambient temperature water output.

[0037] The ambient temperature water control switch 320 can be configured according to actual conditions. For example, the ambient temperature water control switch 320 can be an ambient temperature water control solenoid valve.

[0038] It should be noted that during the use of the water purifier, there may be situations where the flow rate of purified water from the purification device 100 is greater than the flow rate of purified water from the heating module 310 or the room temperature water control switch 320. For example, when a user wants hot water at a certain temperature, the heating module 310 is turned on while the room temperature water control switch 320 is turned off. In this case, the flow rate of hot water will be less than the flow rate of purified water produced by the purification device 100, resulting in higher pressure inside the water circuit, which may damage the components in the water circuit.

[0039] Therefore, in this embodiment, the second water outlet B is also connected to the purification device 100. The pure water flowing out through the second water outlet B can also flow back into the purification device 100, thus forming a pure water return loop. Thus, when there is high pressure inside the water circuit, the pure water return loop can divert some water flow, allowing excess pure water to flow back to the purification device 100, forming a circulation, effectively preventing excessive pressure in the hot water channel from damaging the water circuit.

[0040] In one embodiment, such as Figure 4 As shown, the purification device 100 includes a first purification component 110, a second purification component 120, and a third purification component 130. The inlet of the first purification component 110 is used to connect the raw water to be purified. The outlet of the first purification component 110 is connected to the inlet of the second purification component 120. The outlet of the second purification component 120 is connected to the inlet of the third purification component 130. The outlet of the third purification component 130 serves as the outlet of the purification device 100.

[0041] Specifically, the first purification component 110 can be a preliminary filtration component for preliminary purification of the raw water. The second purification component 120 can be a deep purification component for further purification of the water after preliminary purification by the first purification component 110. The third purification component 130 can be a taste improvement component for further filtration of the water obtained from deep purification to improve the taste of the final pure water.

[0042] For example, the second purification component 120 may be selected from one or more of RO membrane filter cartridges, ultrafiltration membrane filter cartridges, ceramic membrane filter cartridges, and nanofiltration membrane filter cartridges. In one embodiment, the second purification component 120 is selected as an RO membrane filter cartridge. The first purification component 110 may be selected as a pre-filter cartridge, and the third purification component 130 may be selected as a post-filter cartridge. In actual implementation, the pre-filter cartridge and the post-filter cartridge may be integrated into a composite filter cartridge. The pre-filter cartridge may be a PAC filter cartridge or a PP + pre-activated carbon filter cartridge or other filter cartridge forms, and the post-filter cartridge may be an activated carbon filter cartridge or an ultrafiltration + post-activated carbon filter cartridge or other filter cartridge forms.

[0043] The raw water to be purified first passes through a pre-filter to remove impurities such as sediment, rust, and solid pollutants. Then it flows into an RO membrane filter to remove bacteria, viruses, and other small pollutants. The purified water then passes through a post-filter for further filtration, which adsorbs residual odors and discoloration, improving the taste and resulting in pure water.

[0044] It is understood that, in actual implementation, the purification device 100 may also include an inlet valve, a flow meter, a pressure stabilizing pump, and a concentrate regulating valve, etc. In one embodiment, please refer to... Figure 5 An inlet valve 101, a first flow meter 102, and a pressure-stabilizing pump 103 are disposed between the first purification component 110 and the second purification component 120. Water initially purified by the first purification component 110 is pressurized by the pressure-stabilizing pump 103 and flows to the second purification component 120 for filtration. The inlet valve 101 controls the flow of water into the second purification component 120. The first flow meter 102 can be a pulse counter used to count the water flow. A concentrate regulating valve 104 is disposed on the concentrate pipeline connected to the second purification component 120 to control the on / off state of the concentrate pipeline.

[0045] The purification device 100 may also include a first TDS (Total Dissolved Solids) detection component 105 disposed at the outlet of the first purification component 110 for detecting water quality.

[0046] Furthermore, such as Figure 5 As shown, the water system of the water purifier also includes a pure water return valve 501, and the second outlet B of the stepless regulating valve device 200 is connected to the purification device 110 through the pure water return valve 501.

[0047] Specifically, the water circuit where the pure water return valve 501 is located can be connected to the water circuit between the first purification component 110 and the second purification component 120, thereby enabling the return pure water to circulate. The pure water return valve 501 can be a solenoid valve to regulate the on / off state of the return pure water and the precise water flow rate.

[0048] In one embodiment, the water system further includes an anti-backflow component 502, which is disposed between the pure water return valve 501 and the purification device 100 to prevent backflow of water from the purification device 100, thereby improving the stability of the water system. Specifically, the anti-backflow component 502 can be a pure water return check valve, and is disposed between the water path connecting the first purification component 110 and the second purification component 120 and the pure water return valve 501.

[0049] In one embodiment, the water system of the water purifier further includes a pressure switch 503, which is disposed between the outlet end of the purification device 110 and the inlet end of the stepless regulating valve device 200.

[0050] In practical implementation, when the pressure switch 503 detects that the pressure in the water circuit exceeds a certain value, it will shut down the water system, for example, by stopping the water inlet assembly from supplying water. Thus, by setting the pressure switch 503, the safety of the water system can be improved.

[0051] It is understood that, in actual implementation, those skilled in the art can add or remove components to the water system according to actual needs. For example, in some embodiments, the water system may further include a second flow meter 504, an inlet temperature sensor 505, and a second TDS detection component 507, all disposed between the pressure switch 503 and the stepless regulating valve device 200. The second flow meter 504 may be a pulse counter used to detect the flow rate of the pure water. The inlet temperature sensor 505 is used to detect the temperature of the pure water. The second TDS detection component 507 is used to detect the quality of the pure water.

[0052] In some embodiments, the heating device may further include a hot water temperature sensor 301 and an outlet temperature sensor 302, both of which are disposed in the water path between the heating module 310 and the outlet assembly 400. The hot water temperature sensor 301 is disposed near the outlet end of the heating module 310 to collect the temperature of the hot water heated by the heating module 310. The outlet temperature sensor 302 is disposed near the outlet assembly 400 to collect the temperature of the water supplied to the user.

[0053] Compared to the traditional self-priming pump and zero-pressure valve solution, the water system of the aforementioned water purifier uses a compact stepless regulating valve. This results in a smaller overall size and requires less space, improving space utilization and promoting miniaturization and portability. Furthermore, compared to the combination of a self-priming pump and zero-pressure valve, the stepless regulating valve offers higher operational stability and resistance to external interference, ensuring continuous and reliable hot water output, reducing equipment failure rates, and enhancing the user experience. In addition, the stepless regulating valve features continuously adjustable valve opening, enabling precise water flow control for more accurate and efficient flow regulation, thus meeting the needs of different hot water output levels.

[0054] In one embodiment, a water purifier is provided, such as Figure 6 As shown, it includes a controller 610 and a water system 620 for a water purifier.

[0055] When setting up the water system 620 for the water purifier, you can refer to... Figure 1The water system 620 of the water purifier includes a purification device 100, a stepless regulating valve device 200, a heating device 300, and a water outlet assembly 400. The inlet end of the stepless regulating valve device 200 is connected to the outlet end of the purification device 100, the outlet end of the stepless regulating valve device 200 is connected to the inlet end of the heating device 300, and the outlet end of the heating device 300 is connected to the water outlet assembly 400.

[0056] In practical implementation, the water system of the water purifier also includes an inlet component for connecting to an external water supply. Specifically, in scenarios where the raw water pressure from the external water supply is stable, the inlet of the purification device 100 can be directly connected to the inlet component of the water system. In scenarios where the water pressure is unstable, the water system can also include a pressure reducing valve. The inlet of the purification device 100 is connected to the outlet of the pressure reducing valve, and the inlet of the pressure reducing valve is connected to the inlet component. This allows the pressure reducing valve to regulate the inlet pressure, ensuring that all components of the water purifier operate within a suitable pressure range.

[0057] The purification device 100 is used to purify the raw water supplied from the external water supply to obtain purified water. A stepless regulating valve 200 is installed before the heating device 300; adjusting its valve opening regulates the water flow into the heating device 300. The heating device 300 heats the incoming purified water and outputs the heated water through the water outlet assembly 400. It can be understood that when the user needs room temperature water, the heating device 300 can be turned off, and the water output through the water outlet assembly 400 will then be room temperature water.

[0058] The structure of the water outlet assembly 400 can be configured according to actual conditions, for example, including a water outlet nozzle, with the heating device 300 connected to the water outlet nozzle. The stepless regulating valve device 200 is a device including a stepless regulating valve. In one embodiment, such as... Figure 2 As shown, the stepless regulating valve device 200 includes a stepless regulating valve 210 and a drive motor 220 that are mechanically connected. The inlet end of the stepless regulating valve 210 is connected to the outlet end of the purification device 100, and the outlet end of the stepless regulating valve 210 is connected to the inlet end of the heating device 300.

[0059] The stepless regulating valve 210 is a valve capable of continuously and steplessly adjusting the opening of the water flow channel. The drive motor 220 is used to drive the valve core of the stepless regulating valve 210 to move, thereby changing the valve opening. The mechanical connection between the stepless regulating valve 210 and the drive motor 220 results in a smaller overall size and less space required compared to the structure of a self-priming pump that requires a zero-pressure valve. In practical applications, a stepless regulating valve device integrating the stepless regulating valve 210 and the drive motor 220 can be used, resulting in a more compact overall structure and significantly reduced space occupation.

[0060] In one embodiment, such as Figure 3 As shown, the continuously variable valve device 200 has a first outlet A and a second outlet B at its outlet. The heating device 300 includes a heating module 310 and a room temperature water control switch 320. The inlet of the heating module 310 is connected to the first outlet A, and the inlet of the room temperature water control switch 320 is connected to the second outlet B. Both the outlets of the heating module 310 and the room temperature water control switch 320 are connected to the outlet assembly 400. The second outlet B is also connected to the purification device 100. Raw water first enters the purification device 100 for purification. The purified water is then divided into two streams after passing through the continuously variable valve device 200. One stream enters the heating module 310 through the first outlet A for heating, and the heated water flows to the outlet assembly 400 as hot water. The other stream flows through the second outlet B, passes through the room temperature water control switch 320, and flows to the outlet assembly 400 as room temperature water.

[0061] The ambient temperature water control switch 320 can be configured according to actual conditions. For example, the ambient temperature water control switch 320 can be an ambient temperature water control solenoid valve.

[0062] In one embodiment, such as Figure 4 As shown, the purification device 100 includes a first purification component 110, a second purification component 120, and a third purification component 130. The inlet of the first purification component 110 is used to connect the raw water to be purified. The outlet of the first purification component 110 is connected to the inlet of the second purification component 120. The outlet of the second purification component 120 is connected to the inlet of the third purification component 130. The outlet of the third purification component 130 serves as the outlet of the purification device 100.

[0063] Specifically, the first purification component 110 can be a preliminary filtration component for preliminary purification of the raw water. The second purification component 120 can be a deep purification component for further purification of the water after preliminary purification by the first purification component 110. The third purification component 130 can be a taste improvement component for further filtration of the water obtained from deep purification to improve the taste of the final pure water.

[0064] For example, the second purification component 120 may be selected from one or more of RO membrane filter cartridges, ultrafiltration membrane filter cartridges, ceramic membrane filter cartridges, and nanofiltration membrane filter cartridges. In one embodiment, the second purification component 120 is selected as an RO membrane filter cartridge. The first purification component 110 may be selected as a pre-filter cartridge, and the third purification component 130 may be selected as a post-filter cartridge. In actual implementation, the pre-filter cartridge and the post-filter cartridge may be integrated into a composite filter cartridge. The pre-filter cartridge may be a PAC filter cartridge or a PP + pre-activated carbon filter cartridge or other filter cartridge forms, and the post-filter cartridge may be an activated carbon filter cartridge or an ultrafiltration + post-activated carbon filter cartridge or other filter cartridge forms.

[0065] The raw water to be purified first passes through a pre-filter to remove impurities such as sediment, rust, and solid pollutants. Then it flows into an RO membrane filter to remove bacteria, viruses, and other small pollutants. The purified water then passes through a post-filter for further filtration, which adsorbs residual odors and discoloration, improving the taste and resulting in pure water.

[0066] In practical implementation, the purification device 100 may also include an inlet valve, a flow meter, a pressure stabilizing pump, and a concentrate regulating valve, etc. In one embodiment, please refer to... Figure 5 An inlet valve 101, a first flow meter 102, and a pressure-stabilizing pump 103 are disposed between the first purification component 110 and the second purification component 120. Water initially purified by the first purification component 110 is pressurized by the pressure-stabilizing pump 103 and flows to the second purification component 120 for filtration. The inlet valve 101 controls the flow of water into the second purification component 120. The first flow meter 102 can be a pulse counter used to count the water flow. A concentrate regulating valve 104 is disposed on the concentrate pipeline connected to the second purification component 120 to control the on / off state of the concentrate pipeline.

[0067] The purification device 100 may also include a first TDS (Total Dissolved Solids) detection component 105 disposed at the outlet of the first purification component 110 for detecting water quality.

[0068] Furthermore, such as Figure 5 As shown, the water system of the water purifier also includes a pure water return valve 501, and the second outlet B of the stepless regulating valve device 200 is connected to the purification device 110 through the pure water return valve 501.

[0069] Specifically, the water circuit where the pure water return valve 501 is located can be connected to the water circuit between the first purification component 110 and the second purification component 120, thereby enabling the return pure water to circulate. The pure water return valve 501 can be a solenoid valve to regulate the on / off state of the return pure water and the precise water flow rate.

[0070] In one embodiment, the water system further includes an anti-backflow component 502, which is disposed between the pure water return valve 501 and the purification device 100 to prevent backflow of water from the purification device 100, thereby improving the stability of the water system. Specifically, the anti-backflow component 502 can be a pure water return check valve, and is disposed between the water path connecting the first purification component 110 and the second purification component 120 and the pure water return valve 501.

[0071] In one embodiment, the water system of the water purifier further includes a pressure switch 503, which is disposed between the outlet end of the purification device 110 and the inlet end of the stepless regulating valve device 200.

[0072] In practical implementation, when the pressure switch 503 detects that the pressure in the water circuit exceeds a certain value, it will shut down the water system, for example, by stopping the water inlet assembly from supplying water. Thus, by setting the pressure switch 503, the safety of the water system can be improved.

[0073] It is understood that, in actual implementation, the water system may also include a second flow meter 504, an inlet temperature sensor 505, and a second TDS detection component 507, all located between the pressure switch 503 and the stepless regulating valve device 200. The second flow meter 504 may be a pulse counter used to detect the flow rate of the pure water. The inlet temperature sensor 505 is used to detect the temperature of the pure water. The second TDS detection component 507 is used to detect the quality of the pure water.

[0074] In some embodiments, the heating device may further include a hot water temperature sensor 301 and an outlet temperature sensor 302, both of which are disposed in the water path between the heating module 310 and the outlet assembly 400. The hot water temperature sensor 301 is disposed near the outlet end of the heating module 310 to collect the temperature of the hot water heated by the heating module 310. The outlet temperature sensor 302 is disposed near the outlet assembly 400 to collect the temperature of the water supplied to the user.

[0075] In this embodiment, the controller 610 is electrically connected to the stepless regulating valve device 620, and the controller 610 is used to adjust the opening degree of the stepless regulating valve device 200.

[0076] Specifically, the water purifier may also include an input module electrically connected to the controller 610. The user inputs a water intake command through the input module, which includes target parameters such as the desired water flow rate and water temperature. The water temperature can be a specific temperature value or a hot water setting. The controller 610 receives these target parameters and sends corresponding control signals to the stepless regulating valve device 200 to adjust the opening of the stepless regulating valve in the device 200, thereby achieving precise regulation of the water flow rate. The structure of the input module is not limited; it can be a control panel, buttons, or a communication module capable of communicating with user terminals (such as mobile phones, tablets, wearable devices, etc.).

[0077] In this embodiment, the controller 610 can achieve precise control of the stepless regulating valve device 200, realizing flexible adjustment of water flow and heating temperature, thereby providing users with water that better meets their needs.

[0078] In one embodiment, the water purifier further includes a temperature detection module electrically connected to the controller 610. The temperature detection module is located at the outlet end of the heating device 300 and is used to detect the outlet water temperature of the heating device 300 and output the outlet water temperature parameter to the controller 610. The controller 610 is also used to adjust the opening degree of the stepless regulating valve device 200 according to the outlet water temperature parameter.

[0079] Still with Figure 5 In the example shown, the temperature detection module may include a hot water temperature sensor 301, which is electrically connected to a controller 610. The controller 610 can directly and accurately detect the temperature of the hot water flowing out of the heating module 310 of the heating device 300 through the hot water temperature sensor 301. The outlet water temperature parameter includes the hot water temperature.

[0080] The controller 610 can also send a corresponding control signal to the stepless regulating valve device 200 after comprehensive calculation based on the hot water temperature and target parameters, so as to adjust the opening degree of the stepless regulating valve in the stepless regulating valve device 200 and realize precise regulation of the output water flow and water temperature of the water outlet component 400.

[0081] Furthermore, in some embodiments, the temperature detection module also includes an outlet water temperature sensor 302. Since the hot water output from the heating module 310 experiences a temperature drop as it flows to the outlet water assembly 400, the controller 610 can obtain the accurate temperature of the water supplied to the user through the outlet water temperature sensor 302, thus obtaining the outlet water temperature. In this embodiment, the outlet water temperature parameters include the hot water temperature and the outlet water temperature. The controller 610 can more accurately send corresponding control signals to the stepless regulating valve device 200 based on this outlet water temperature parameter and the target parameter, thereby improving the accuracy of adjusting the opening degree of the stepless regulating valve.

[0082] In one embodiment, the water purifier further includes a water pressure detection module electrically connected to the controller 610, the water pressure detection module being disposed between the water outlet of the purification device 100 and the water inlet of the stepless regulating valve device 200. The water pressure detection module is used to detect water pressure and output water pressure parameters to the controller 610. The controller 610 is also used to control the stepless regulating valve device 610 to close when the water pressure parameter is greater than a preset threshold.

[0083] Specifically, the water pressure detection module can be a pressure switch 503, which is electrically connected to the controller 610. The controller 610 detects the water pressure parameters of the water circuit through the pressure switch 503, and controls the stepless regulating valve device 610 to close when the water pressure parameters exceed a preset threshold, thereby ensuring that the stepless regulating valve operates in a stable working state, improving the safety of the entire water circuit, and thus improving the safety of the water purifier.

[0084] To better understand the above embodiments, the following is combined with... Figure 1-6 The embodiments are explained in detail.

[0085] After the controller 610 of the water purifier receives the instruction to take warm water, if the water take instruction indicates that the user wants to take room temperature water, it controls the second outlet B (i.e., one end of the room temperature water flow channel) of the stepless regulating valve device 200 to be fully open and the first output A (i.e., one end of the hot water flow channel) to be fully closed. At the same time, the room temperature water control switch 320 is opened and the pure water return valve 501 is closed to ensure that the outlet flow rate of room temperature water is consistent with the purified water flow rate produced by the purification module 200.

[0086] If the water demand command indicates that the user wants hot water, the controller 610 controls the ambient temperature water control switch 320 to close, the heating module 310 to open, and controls the first output terminal A of the stepless regulating valve in the stepless regulating valve device 200 to open partially. At the same time, based on the outlet water temperature parameters fed back by the hot water temperature sensor 301 and the outlet water temperature sensor 302, the opening size of the first output terminal A is dynamically adjusted to ensure that the temperature of the water flowing out of the outlet of the water outlet component 400 is within the deviation range of the temperature selected by the user.

[0087] Because the hot water flow rate is less than the pure water flow rate produced by the purification module 100, the first output terminal A will not be fully opened during the hot water preparation process, and some water will be diverted from the second output terminal B. At this time, the pure water return valve 501 opens, allowing excess room temperature pure water to flow back to the purification module 100 to form a circulation. This portion of water flow can prevent excessive pressure in the hot water channel from damaging the water circuit.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
