The utility model effectively solves the problem that the water purifier can only provide a single type of purified water. It can not only provide instant hot water or cold water, but also provide domestic water for users. It can also control the instant heating module through the control element to realize the flexible conversion between normal temperature water and heated water, thus realizing the refined management of household water use, improving the richness of the water system, and also greatly facilitating the diversified water needs of users in daily life.

[0022] Specifically, the water inlet pipeline connected to the raw water end and the concentrated water pipeline connected to the concentrated water end ensure the normal operation of the water purifier and the discharge of wastewater.

[0023] In addition, the filtration module plays the role of filtering and purifying water quality. The water outlet pipes of the water purifier are divided into domestic water pipes and drinking water pipes. Such a setting can flexibly meet the different water needs of users. Specifically, the domestic water pipes can meet the daily washing, cleaning and other needs of users, while the drinking water pipes can provide high-quality drinking water.

[0024] Furthermore, as a preferred embodiment of the present invention but not a limitation, a cooling module and an instant heating module are provided in the drinking water pipeline, so that users can enjoy cold water or hot water as needed, greatly improving the practicality and user experience of the water purifier. Specifically, the cooling module can provide users with cool drinking water on hot summer days, while the instant heating module can heat the water temperature in a short time to meet the user's need to enjoy hot water at any time.

[0027] like Figure 2 The water system of a water purifier shown in the figure, the refrigeration module 71 includes an ice bladder 711 connected to the drinking water pipeline 7, and a cold water outlet pipeline 712 connected to the water outlet end of the ice bladder 711, the cold water outlet pipeline 712 is provided with a cold water outlet 7121, the upstream end of the ice bladder 711 is provided with a refrigeration module solenoid valve 7111, the ice bladder 711 and the refrigeration module solenoid valve 7111 are respectively connected to the control element 5, and the ice bladder 711 is also provided with a sewage outlet 7112. Further, as a preferred embodiment of the utility model but not a limitation, the ice bladder is connected to the drinking water pipeline, and when cold water is needed, the drinking water will flow into the ice bladder through the drinking water pipeline to form a water inlet channel. The ice bladder can reduce the water temperature through the cooling element to achieve a cooling effect. For example, the ice tank is equipped with refrigerant and cooling components. The cooling components can cool the ice tank. Through the circulation of the refrigerant, the water temperature can be effectively lowered.

A refrigeration module solenoid valve is provided at the upstream end of the refrigeration module. The refrigeration module solenoid valve is connected to the control element, and can open or close the water inlet channel of the ice tank according to the user's instructions or preset program. When the user does not need cold water, the refrigeration module solenoid valve can be closed to avoid unnecessary energy consumption and waste of water resources. This setting enables the refrigeration module to be seamlessly connected with the water system of the water purifier, which not only ensures the continuous supply of cold water, but also ensures the purity of the water quality.

[0029] Optionally, in some embodiments, the ice container is further provided with a sewage outlet, which can ensure the cleanliness of the interior of the ice container and discharge sewage, thereby ensuring the purity and sanitation of the cold water. Specifically, during long-term use, some dirt or bacteria will accumulate inside the ice container, affecting the quality and taste of the cold water. By regularly opening the sewage outlet, when cleaning the interior of the ice container or discharging accumulated stale water, drainage can be performed through the sewage outlet, thereby ensuring the cleanliness of the ice container and the quality of the cold water.

[0030] Specifically, the entire working process of the refrigeration module is monitored and adjusted by the control element. The control element can intelligently adjust the working state of the refrigeration module according to user needs, ambient temperature and other factors to ensure that the supply of cold water is sufficient and energy-saving.

[0031] like Figure 2 A water system of a water purifier is shown, the instant heating module 72 includes a heating element 721 connected to the drinking water pipeline 7, and a hot water outlet pipeline 722 connected to the water outlet end of the heating element 721, the hot water outlet pipeline 722 is provided with a hot water outlet 7221, and the heating element 721 is connected to the control element 5. Further, as a preferred embodiment of the utility model but not limited to, the heating element is connected to the drinking water pipeline, and when hot water is needed, the drinking water will flow into the heating element through the drinking water pipeline to form a water inlet channel. Optionally, in some embodiments, the heating element is heated by an electric heating film or a quartz tube, which can heat the water flow to the required temperature in a short time. The instant heating module can meet the user's immediate demand for hot water. By combining the instant heating module with the water system of the water purifier, the instant supply and precise control of hot water are realized, which improves the practicality and user experience of the water purifier. Specifically, the water outlet end of the heating element is connected to the hot water outlet pipeline, and the hot water outlet pipeline is provided with a hot water outlet, which is convenient for users to directly take hot water. This arrangement allows the instant heating module to be closely integrated with the water system of the water purifier, achieving instant supply of hot water.

[0032] Furthermore, as a preferred embodiment of the present invention but not a limitation, in order to realize the control of the working state of the heating element, the heating element is connected to the control element. The control element can adjust the heating power and working time of the heating element according to the user's instructions or preset programs. The user can select a suitable hot water temperature according to his or her needs. When warm water is not needed, the heating element can be stopped by the control element, thereby obtaining normal temperature water and avoiding unnecessary energy consumption.

[0033] Optionally, in some embodiments, in order to ensure the safe operation of the instant heating module, when the temperature of the heating element is too high or the water flow is too small, the control element will automatically shut down the heating element to avoid overheating or dry burning, thereby effectively ensuring the safety of the user.

[0034] like Figure 2A water system of a water purifier shown in the figure, the domestic water pipeline 6 is provided with a domestic water outlet 61, a domestic water pipeline solenoid valve 62 located between the domestic water outlet 61 and the pure water end 102, and a domestic water pipeline one-way valve 63 connected to the domestic water pipeline solenoid valve 62, and the domestic water pipeline solenoid valve 62 is connected to the control element 5. Further, as a preferred embodiment of the utility model but not limited thereto, the domestic water pipeline is connected to the domestic water outlet, and the user can obtain non-drinking water, such as water for washing, cleaning, etc., through this domestic water outlet. A domestic water pipeline solenoid valve is set between the domestic water outlet and the pure water end. When the user needs non-drinking water, the control element will send a signal to the domestic water pipeline solenoid valve to open it, allowing pure water to flow to the domestic water outlet through the domestic water pipeline. On the contrary, when non-drinking water is not needed, the domestic water pipeline solenoid valve will be closed, thereby preventing water from flowing through. The domestic water pipeline can also ensure the one-way flow of water by installing a domestic water pipeline one-way valve to prevent water from flowing back or reflux, which helps to keep the pipeline clean and sanitary and avoid cross-contamination between different water sources.

[0035] Specifically, the control element can intelligently adjust the switch state of the solenoid valve of the domestic water pipeline according to the user's water demand, water use time and other factors, thereby realizing precise control of non-drinking water. Such a setting not only improves the use efficiency of the water purifier, but also meets the diverse water needs of users. By reasonably configuring and controlling the domestic water pipeline, users can easily obtain non-drinking water suitable for washing, cleaning and other purposes, while avoiding the waste of water resources.

[0036] like Figure 2 The water system of a water purifier shown in the figure, the domestic water pipeline 6 is also provided with a wastewater ratio solenoid valve 64 and a high and low pressure switch 65, the wastewater ratio solenoid valve 64 is located at the downstream end of the domestic water pipeline solenoid valve 62, the high and low pressure switch 65 is located between the domestic water pipeline check valve 63 and the domestic water outlet 61, and the wastewater ratio solenoid valve 64 and the high and low pressure switch 65 are respectively connected to the control element 5. Further, as a preferred embodiment of the utility model but not limited to, the wastewater ratio solenoid valve is located at the downstream end of the domestic water pipeline solenoid valve, and its function is to control the flow rate of wastewater, ensure the discharge efficiency of wastewater and the operation effect of the water purifier. Specifically, a certain proportion of wastewater will be generated in the reverse osmosis filtration system, and the wastewater ratio solenoid valve can be used to control the proportion of wastewater generated, thereby optimizing the water efficiency utilization rate of the system and saving water resources. Specifically, the wastewater ratio solenoid valve is connected to the control element, allowing the user or the system to automatically adjust the wastewater flow rate according to the preset program or real-time monitoring data. By controlling the opening and closing of the wastewater ratio solenoid valve, it can be ensured that only an appropriate amount of wastewater is released when using domestic water, reducing the waste of water resources.

[0037] In addition, the high and low pressure switches are located between the one-way valve and the domestic water outlet of the domestic water pipeline. The high and low pressure switches can monitor the water pressure in the pipeline. By detecting the high and low water pressure, the operating status of the water purifier can be monitored and protected.

[0038] Optionally, in some embodiments, when the water pressure is too high or too low, the high and low pressure switches will automatically cut off the power supply to prevent equipment damage or unnecessary energy consumption while protecting user safety.

[0039] Optionally, in some embodiments, the high and low pressure switches are connected to the control element, which can transmit water pressure data in real time and send out an alarm or automatically take control measures when the water pressure is abnormal. When the water pressure is too high, the high pressure switch of the high and low pressure switch will be triggered and send a signal to the control element, and the control element will then take measures to reduce the water pressure, such as slowing down the running speed of the booster pump to prevent the pipeline from rupturing or the water purifier from being damaged due to high pressure. On the contrary, when the water pressure is too low, the low pressure switch of the high and low pressure switch will be activated to remind the user or the control element to take corresponding measures, such as checking whether the water source is sufficient or whether there is a pipeline leak.

[0040] Specifically, the control element can adjust the operating state of the water purifier according to the proportion of wastewater and the pressure of the pipeline. Users can adjust the wastewater proportion and the water pressure of the monitoring system according to actual needs to ensure its normal operation and achieve the expected purification effect, while making the use process more economical and efficient.

[0041] like Figure 2 The water system of a water purifier shown in the figure, the water inlet pipeline 3 includes a water inlet 31, a water inlet pipeline solenoid valve 32 near the side of the water inlet 31, and a booster pump 33 connected between the water inlet pipeline solenoid valve 32 and the pure water end 102, and the water inlet pipeline solenoid valve 32 is connected to the control element 5. Further, as a preferred embodiment of the utility model but not limited to, the water inlet pipeline solenoid valve is connected to the control element, and the control element can control the switch state of the water inlet pipeline, and control the flow rate and time of water inlet as needed. The water inlet pipeline solenoid valve can accurately control the on and off of water inlet according to the instructions of the control element. When the water purifier needs to work, the control element will send a signal to the water inlet pipeline solenoid valve to open it, allowing raw water to enter the water inlet pipeline from the water inlet; when the water purifier does not need to work or needs to be shut down for maintenance, the water inlet pipeline solenoid valve will be closed to cut off the water inlet. A booster pump is connected between the solenoid valve of the water inlet pipeline and the pure water end of the filter module. The function of the booster pump is to increase the pressure of the incoming water. The booster pump can ensure the stability of the water flow rate and pressure, ensure that the raw water can pass through the filter module smoothly, and achieve the expected filtering effect.

[0042] Specifically, the water inlet line solenoid valve and the booster pump are both connected to the control element, which enables the working state of the entire water inlet line to be precisely controlled. The control element can intelligently adjust the switch state of the water inlet line solenoid valve and the working power of the booster pump according to factors such as the operating state of the water purifier, water demand, and the working state of the filter module. This intelligent control method not only improves the operating efficiency of the water purifier, but also extends the service life of the equipment.

[0043] Specifically, when the water purifier is started, the control element sends a signal to the water inlet line solenoid valve, which opens to allow raw water to flow into the water purifier. Subsequently, the booster pump starts working to increase the water pressure to meet the needs of the filter module. The pressurized water flows through the filter module to remove impurities and harmful substances, and finally produces pure water. When the water purifier is turned off or the water supply needs to be stopped, the control element will send a signal to close the water inlet line solenoid valve, thereby cutting off the supply of raw water and stopping the booster pump to ensure the safety and energy saving of the system.

[0044] like Figure 1 A water system of a water purifier is shown, wherein a reflux pipeline 8 is provided between the water inlet pipeline 3 and the water outlet pipeline 2, and the reflux pipeline 8 includes a reflux water inlet end 81 located on the water outlet pipeline 2, a reflux water outlet end 82 located on the water inlet pipeline 3, and a reflux pipeline one-way valve 83 located between the reflux water inlet end 81 and the reflux water outlet end 82. Further, as a preferred embodiment of the utility model but not a limitation, the reflux water inlet end is located on the water outlet pipeline, and is used to reintroduce part of the pure water into the reflux pipeline, and the reflux water outlet end is located on the water inlet pipeline, and is used to introduce part of the incoming water into the water inlet pipeline. The reflux pipeline one-way valve can ensure that the water flow can only flow from the reflux water inlet end to the reflux water outlet end, and cannot flow in the opposite direction, thereby preventing wastewater from contaminating pure water, and also preventing raw water from flowing into the drinking water pipeline to cause pollution.

[0045] Specifically, the return line can help regulate the pressure in the system. When the system is started or shut down, it can prevent water hammer caused by pressure fluctuations, thereby protecting pipes and equipment from damage and avoiding pipe damage or leakage caused by sudden pressure changes. The purified water can pass through the filtration system of the water purifier again to improve the utilization rate of water resources.

[0046] Optionally, in some embodiments, the return line can stabilize the pressure difference on the surface of the filter membrane to a certain extent through circulating flow, which helps to maintain the filtration efficiency.

[0047] Optionally, in some embodiments, the reflux line can help flush the filter membrane through circulating flow, flush out impurities accumulated on the membrane surface, delay membrane clogging, thereby extending the service life of the filter membrane and ensuring continuous and stable water quality output.

[0048] like Figure 1 to Figure 2 The water system of a water purifier shown in the figure, the reflux water inlet end 81 is located between the domestic water pipeline 6 and the drinking water pipeline 7, and the reflux water outlet end 82 is located between the water inlet pipeline solenoid valve 32 and the booster pump 33. The reflux water inlet end is located between the domestic water pipeline and the drinking water pipeline, which helps to ensure the quality of the reflux water and avoid mixing between drinking water and domestic water. When there is unused water in the domestic water pipeline or the drinking water pipeline, this water can be effectively recycled. Through the reflux pipeline, this water can re-enter the water inlet pipeline and be purified again for use by users. This avoids the waste of water resources and improves the use efficiency of the water purifier.

[0049] Specifically, the reflux outlet is located between the solenoid valve and the booster pump of the water inlet pipeline, which helps to reintroduce the refluxed water into the water inlet pipeline to maintain the circulation and balance of the pipeline. This reduces pipeline damage and leakage caused by pressure fluctuations. Through such a setting, the reflux pipeline is conducive to the self-cleaning and long-lasting performance of the filter medium, and can achieve the reuse of wastewater, while ensuring that wastewater will not mix with pure drinking water, ensuring the safe and stable operation of the water purifier system.

[0050] like Figure 2 The water system of a water purifier shown in the figure, the concentrated water pipeline 4 is provided with a wastewater valve 41 connected to the concentrated water end 103, a wastewater port 42, and a water receiving box assembly 43 connected between the wastewater valve 41 and the wastewater port 42, the water receiving box assembly 43 includes a water receiving box 431 located between the wastewater valve 41 and the wastewater port 42, and a pump body 432 connected to the water receiving box 431, the pump body 432 is used to drive the water in the water receiving box 431 to flow to the wastewater port 42, the pump body 432 is a two-way non-return pump and is connected to the control element 5. Further, as a preferred embodiment of the utility model but not limited thereto, the concentrated water pipeline is provided with a wastewater valve connected to the concentrated water end, which can control the flow of concentrated water or wastewater. By controlling the switch state of the wastewater valve, wastewater backflow or leakage is prevented.

[0051] Optionally, in some embodiments, the wastewater outlet serves as an outlet for concentrated water and is responsible for discharging the treated wastewater to a suitable place. The wastewater outlet can be connected to a container for storing wastewater or can be connected to a sewer.

[0052] Furthermore, as a preferred embodiment of the utility model but not a limitation, the water receiving box is used to temporarily store concentrated water flowing out of the wastewater valve. The water receiving box has a certain capacity and sealing performance to ensure that it can accommodate a certain amount of concentrated water and prevent leakage. The function of the pump body is to drive the water in the water receiving box to flow to the wastewater outlet through power to achieve the discharge of wastewater. The two-way check function of the two-way check pump can ensure the directionality of the water flow and prevent the backflow or reflux of the water flow. The two-way check pump is connected to the control element so that the discharge of wastewater can be precisely controlled according to the instructions of the control element. The control element can intelligently adjust the operating state of the pump body according to factors such as the working state of the water purifier, the amount of wastewater generated, and the user's operation, to ensure the timely discharge and rational use of wastewater.

[0053] Specifically, during the operation of the water purifier, the waste water generated will flow into the water receiving box. When the waste water needs to be discharged, the control element will send a signal to the two-way check pump, and the pump body will start working to push the waste water in the water receiving box to the waste water outlet and discharge it.

[0054] like Figure 3 The water system of a water purifier shown in the figure, the outlet end of the sewage outlet 7112 is connected to the concentrated water pipeline 4, and the sewage outlet 7112 is provided with a sewage outlet check valve 71121 and a sewage outlet solenoid valve 71122. Further, as a preferred embodiment of the utility model but not a limitation, the sewage outlet is located on the ice tank, which is used to discharge the stale water, sediments in the ice tank or liquids that need to be discharged during cleaning and maintenance. The outlet end of the sewage outlet is interconnected with the concentrated water pipeline, so that the sewage discharged from the ice tank will directly flow into the concentrated water pipeline, and then be discharged from the water purifier through the wastewater outlet. The sewage outlet check valve can ensure that the sewage can only flow from the ice tank to the concentrated water pipeline in one direction, preventing reverse backflow and causing secondary pollution. The sewage outlet solenoid valve is connected to the control element, and the switch state of the sewage outlet can be intelligently controlled by the control element to ensure that it is opened in time when sewage discharge is required, and kept closed when sewage discharge is not required, thereby realizing the automatic control and precise management of the sewage discharge work of the ice tank.

[0055] Specifically, when the ice tank needs to be cleaned or maintained, the user or maintenance personnel can open the sewage outlet solenoid valve through the control element. At this time, the wastewater and dirt inside the ice tank flow out through the sewage outlet check valve, enter the concentrated water pipeline, and are finally processed or discharged. When the cleaning or maintenance is completed, the sewage outlet solenoid valve is closed to prevent the liquid from flowing back into the ice tank.

The wastewater ratio solenoid valve 64 is located at the downstream end of the domestic water pipeline solenoid valve 62, and the high and low pressure switch 65 is located between the domestic water pipeline one-way valve 63 and the domestic water outlet 61. The wastewater ratio solenoid valve 64 and the high and low pressure switch 65 are respectively connected to the control element 5.

[0064] The water inlet pipeline 3 includes a water inlet 31 , a water inlet pipeline solenoid valve 32 close to the water inlet 31 , and a booster pump 33 connected between the water inlet pipeline solenoid valve 32 and the pure water end 102 . The water inlet pipeline solenoid valve 32 is connected to the control element 5 .

[0065] A reflux pipeline 8 is provided between the water inlet pipeline 3 and the water outlet pipeline 2, and the reflux pipeline 8 includes a reflux water inlet end 81 located on the water outlet pipeline 2, a reflux water outlet end 82 located on the water inlet pipeline 3, and a reflux pipeline one-way valve 83 located between the reflux water inlet end 81 and the reflux water outlet end 82.

[0066] The reflux water inlet end 81 is located between the domestic water pipeline 6 and the drinking water pipeline 7 , and the reflux water outlet end 82 is located between the water inlet pipeline solenoid valve 32 and the booster pump 33 .

[0067] The concentrated water pipeline 4 is provided with a wastewater valve 41 communicated with the concentrated water end 103, a wastewater port 42, and a water receiving box assembly 43 connected between the wastewater valve 41 and the wastewater port 42. The water receiving box assembly 43 includes a water receiving box 431 located between the wastewater valve 41 and the wastewater port 42, and a pump body 432 connected to the water receiving box 431. The pump body 432 is used to drive the water in the water receiving box 431 to flow to the wastewater port 42. The pump body 432 is a two-way check water pump and is connected to the control element 5.

[0068] When the water purifier is started, the control element 5 sends a signal to the water inlet line solenoid valve 32, and the water inlet line solenoid valve 32 opens, allowing raw water to flow into the water purifier. Subsequently, the booster pump 33 starts working to increase the water pressure to meet the needs of the filter module 100. The pressurized water flows through the filter module 100 to remove impurities and harmful substances, and finally produces pure water. When the water purifier is turned off or the water supply needs to be stopped, the control element 5 will send a signal to close the water inlet line solenoid valve 32, thereby cutting off the supply of raw water and stopping the operation of the booster pump 33 to ensure the safety and energy saving of the system.

[0069] When the user needs non-drinking water, the control element 5 sends a signal to the domestic water pipeline solenoid valve 62 to open it, allowing pure water to flow through the domestic water pipeline 6 to the domestic water outlet 61. Conversely, when non-drinking water is not needed, the domestic water pipeline solenoid valve 62 will be closed, thereby preventing water from flowing through.

[0070] The refrigeration module solenoid valve 7111 is connected to the control element 5 and can open or close the water inlet channel of the ice liner 711 according to the user's instructions or preset programs. When the user does not need cold water, the refrigeration module solenoid valve 7111 can be closed to avoid unnecessary energy consumption and water waste.

[0071] During the operation of the water purifier, the waste water generated will flow into the water receiving box 431. When the waste water needs to be discharged, the control element 5 will send a signal to the two-way check pump, and the pump body 432 will start working to push the waste water in the water receiving box 321 to the waste water port 42 for discharge.

[0072] The utility model effectively solves the problem that the water purifier can only provide a single type of purified water. It can not only provide instant hot water or cold water, but also provide domestic water for users to use. It can also control the instant heating module through the control element 5 to achieve flexible conversion between normal temperature water and heated water, thereby realizing refined management of household water use, improving the richness of the water system, and also greatly facilitating the diversified water needs of users in daily life.

[0073] Example 2

[0074] like Figure 3 As shown, Example 2 further has the following implementation methods based on Example 1, which are as follows: the water outlet end of the sewage outlet 7112 is connected to the concentrated water pipeline 4, and the sewage outlet 7112 is provided with a sewage outlet check valve 71121 and a sewage outlet solenoid valve 71122. When the ice gall 711 needs to be cleaned or maintained, the user or maintenance personnel can open the sewage outlet solenoid valve 71121 through the control element 5. At this time, the wastewater and dirt inside the ice gall 711 flow out through the sewage outlet check valve 71121, enter the concentrated water pipeline 4, and are finally processed or discharged. When the cleaning or maintenance is completed, the sewage outlet solenoid valve 71121 is closed to prevent the liquid from flowing back into the ice gall 711.

[0075] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
