[0002] As society pays more and more attention to drinking water safety, reverse osmosis water purifiers have gradually become indispensable household appliances. Among them, the TDS (Total Dissolved Solids) of the outlet water is the main indicator for measuring the filtration effect of the water circuit system.

[0003] Currently, the water circuit system usually uses reverse osmosis filter elements to filter raw water. When the raw water passes through the reverse osmosis filter element, water molecules penetrate into the pure water side through the membrane under the action of an external pressure, and the filtered waste water is discharged through the waste water side. It can be seen that in the current water circuit system, water resource waste is relatively serious. Summary of the Invention

[0047] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the first implementation manner of the water circuit system provided by the embodiments of the present application. The water circuit system provided in this embodiment specifically includes a purified water pipe 10, a purified water module 20, a pure water circuit 30, a waste water circuit 40, a pure water control valve 50, a waste water control valve 60, and a water quality detector 70; among them, the purified water module 20 includes a pre-filter 201, a reverse osmosis filter 202, a post-filter 203, and a water pump 204; the inlet pipe 10 is connected to the water inlet side of the reverse osmosis filter 202 through the pre-filter 201, and the waste water circuit 40 is connected to the concentrated water side of the reverse osmosis filter 203; the pure water circuit 30 is connected to the pure water side of the reverse osmosis filter 202, and the pure water circuit 30 is also connected to the water inlet side of the reverse osmosis filter 202 through the pre-filter, and the post-filter 203 is connected to the pure water side of the reverse osmosis filter 202; the pure water circuit 30 is connected to the pure water side of the reverse osmosis filter 202 through the post-filter 203, and the pure water circuit 30 is connected to the pre-filter 201 through the post-filter 203; the pure water control valve group 50 is arranged in the pure water circuit 30, the waste water control valve group 60 is arranged in the waste water circuit 40, the water pump 204 is arranged between the pre-filter 201 and the water inlet side of the reverse osmosis 202, the water quality detector 70 is arranged at one end of the pre-filter 201, and the pure water control is connected to the water quality detector 70. The waste water control valve group 60 includes a check valve 601, a waste water valve 602, and a waste water reflux valve 603. The water inlet end of the check valve 601 is connected to the water outlet end of the waste water reflux valve group 603. The water inlet end of the waste water reflux valve group 603 is respectively connected to the concentrated water side of the reverse osmosis filter 202 and the waste water circuit. The water inlet end of the waste water valve 602 is respectively connected to the water inlet end of the waste water reflux valve group 603 and the concentrated water side of the reverse osmosis filter 202.

[0048] One end of the inlet pipe 10 is the raw water inlet end for connecting raw water. The other end of the inlet pipe 10 is connected to the first end of the purified water module for flowing the raw water into the purified water module 20 for purified water treatment. The second end of the purified water module 20 is connected to the first end of the pure water circuit 30 for flowing the purified water obtained after the purified water treatment into the pure water circuit 30. The second end of the pure water circuit 30 serves as the pure water outlet end for flowing out the pure water. The first end of the pure water circuit 30 is also connected to the first end of the purified water module 20 for flowing the purified water into the purified water module 20 to provide the pure water for backwashing and mixing with the raw water. The third end of the purified water module 20 is connected to the first end of the waste water circuit 40 for flowing the waste water into the waste water circuit 40. The second end of the waste water circuit 40 serves as the waste water discharge outlet.

[0049] Specifically, the pre-filter 201 is connected to the concentrated water side of the reverse osmosis filter element 202, and the water inlet pipe 10 is connected to the water inlet side of the reverse osmosis filter element 202 through the pre-filter 201. The raw water flowing out of the water inlet pipe 10 first passes through the pre-filter 201 in the pre-filter and then flows into the water inlet side of the reverse osmosis filter element 202, so as to perform purification and filtration treatment on the raw water through the pre-filter 201 and the reverse osmosis filter element 202. The concentrated water side of the reverse osmosis filter element 202 is also connected to the wastewater circuit 40 for discharging the wastewater on the concentrated water side through the wastewater circuit 40; the pure water side of the reverse osmosis filter element 202 is connected to the pure water circuit 30 to flow out the purified pure water through the pure water circuit 30. In addition, on the basis of connecting the pure water side of the reverse osmosis filter element 202, the pure water circuit 30 is also connected to the concentrated water side of the reverse osmosis filter element 202 through the pre-filter 201. After stopping discharging pure water through the pure water circuit 30, the water inlet end of the post-filter 203 is connected to the pure water side of the reverse osmosis filter element 202 for receiving the pure water flowing out of the pure water side of the reverse osmosis filter element 202. The water outlet end of the post-filter 203 is connected to one end of the pure water circuit, and the pure water flowing out of the post-filter 203 flows into the pure water circuit 30 for discharging for the user to draw water. The water outlet end of the post-filter 203 is also connected to the water inlet end of the pre-filter through the pure water circuit 30. After the pure water flowing out of the post-filter 203 flows into the pure water circuit 30, the pure water is returned to the water inlet end of the pre-filter through the pure water circuit 30, so as to mix the pure water returned to the pre-filter 201 in the pre-filter with tap water in a certain proportion and enter the reverse osmosis filter element 202 with a membrane to wash the membrane for a period of time, so that the reverse osmosis membrane is washed and soaked by water with a lower TDS, and the concentration of the first glass of water next time will be relatively low; then, by flowing the pure water flowing out of the post-filter into the pure water circuit and discharging it, the TDS value of the first glass of water next time will be lower.

[0050] Specifically, after the raw water passes through the water inlet 10, it first passes through the pre-filter 201, and then, under the action of the water pump 204, enters the water inlet side of the reverse osmosis filter element 202, and then, the wastewater flows out from the concentrated water side of the reverse osmosis filter element 202 to the wastewater circuit.

[0051] Among them, generally, in a reverse osmosis water purification device, the raw water first passes through the pre-filter, then enters the water inlet side of the reverse osmosis filter element through a pump, and then the wastewater is discharged from the concentrated water side; specifically, the process of wastewater reflux is from the concentrated water side of the reverse osmosis filter element 202 back to between the water pump 204 and the pre-filter 201, and after passing through the water pump 204, it is refluxed to the water inlet side of the reverse osmosis filter element 202, and through reverse osmosis filtration twice, the purpose of water saving is achieved; the process of pure water reflux is from the pure water side of the reverse osmosis filter element 202 back to before the pre-filter 201, and after being pressurized by the water pump 204, it enters the water inlet side of the reverse osmosis filter element 202, and then through the flushing of the reverse osmosis filter element 202, the wastewater is discharged from the concentrated water side of the reverse osmosis filter element 202.

[0052] The pure water flowing out of the pure water side of the reverse osmosis filter element 202 is returned to the pre-filter element 201 through the post-filter element 203 via a pure water circuit, so as to filter the pure water again through the pre-filter element 201, pass through the water inlet side of the reverse osmosis filter element 202, be combined with tap water in a certain proportion and then enter the reverse osmosis filter element, and rinse the filter membrane for a period of time to achieve the effect of three-stage buffering. Thus, the pure water side can output pure water with a lower TDS value, making the concentration of the first glass of water lower next time, further reducing the TDS value, and effectively solving the problem of a relatively high TDS value for short-frequency water intake.

[0053] It can be understood that in this embodiment, after producing a certain volume / time of water, the water intake is ended and the reflux flushing is started. The pure water reflux is turned on, and the pure water is returned to the pre-filter element and combined with tap water in a certain proportion, and then enters the membrane-containing filter element to rinse the membrane for a period of time. At this time, the membrane is rinsed and soaked by water with a lower TDS. The concentration of the first glass of water next time will be lower than the previous concentration, thus solving the problem of a relatively high TDS value for the first glass of water and reducing the TDS value for short-frequency water intake.

[0054] Further, the pure water circuit 30 in this embodiment may specifically include a first pure water branch 31 and a second pure water branch 32. Among them, the first pure water circuit 31 is connected to the water outlet end of the post-filter element 203 and is used to directly discharge the pure water flowing out of the post-filter element 203 to provide pure water for users to drink. The second pure water circuit 32 is respectively connected to one end of the first pure water branch 31, the water outlet end of the post-filter element 203, the water outlet end of the water inlet pipe 10, and the water inlet end of the pre-filter element 201. When the pure water reflux mode is turned on, the second pure water circuit 32 returns the pure water flowing out of the water outlet end of the post-filter element 203 to the water inlet end of the pre-filter element 201, and mixes it with the raw water flowing out of the water outlet end of the water inlet pipe 10. The pure water is returned to the pre-filter element 201 and mixed with the tap water flowing out of the water inlet pipe according to a certain proportion, and the mixed water flows into the reverse osmosis filter element 202 to rinse the reverse osmosis membrane, so that the reverse osmosis membrane is rinsed and soaked by water with a lower TDS. Therefore, the concentration of the first glass of water next time will be lower, providing better TDS buffering ability for the next water intake.

[0055] Optionally, in some embodiments, the wastewater circuit 40 may specifically include a first wastewater branch 41 and a second wastewater branch 42. One end of the first wastewater branch 41 is respectively connected to the water inlet end of the second wastewater branch 42 and one end of the pre-filter element 201, and the other end of the first wastewater branch 41 is connected to the other end of the pre-filter element 201. The wastewater is refluxed through the first wastewater branch 41 and returned between the buffer tank and the water pump of the pre-filter element 201; the water inlet end of the second wastewater branch 42 is respectively connected to one end of the first wastewater branch 41 and the concentrated water side of the reverse osmosis filter element 202, and the water outlet end of the second wastewater branch 42 is used as the wastewater discharge outlet, and the wastewater flowing out of the concentrated water side of the reverse osmosis filter element 202 is discharged through the second wastewater branch 42.

[0056] It can be seen that when the raw water passes through the reverse osmosis filter element 201, under the action of the applied pressure, water molecules pass through the membrane into the pure water side, and the filtered wastewater is discharged through the wastewater side. It can be seen that in the current waterway system, water resources are wasted severely.

[0057] Based on this, the present application provides a control method for a waterway system. Please refer to Figure 2 , Figure 2 which is a schematic flow chart of the control method for the waterway system provided by the embodiments of the present application, specifically as follows:

[0058] S101. Detect the water quality of the waterway system.

[0059] For example, specifically, the water quality detector 70 provided in the water inlet pipe 10 can be used to detect the water quality of the waterway system. When the water quality of the waterway system meets the preset conditions, step S102 is executed. When the water quality of the waterway system does not meet the preset conditions, the water production continues according to the set purified water reflux mode of the waterway system.

[0060] Among them, the TDS value can measure the purity of water quality. The TDS value of domestic drinking water should be ≤1000 mg / L to be normal. TDS is the total dissolved solids concentration in water (mg / L), which mainly reflects the concentrations of plasma such as Ca2+, Mg2+, Na+, and K+ in water, and has a good corresponding relationship with water hardness and conductivity. The smaller the TDS, the lower the concentrations of plasma such as Ca2+, Mg2+, Na+, and K+ in water, and the smaller the conductivity. Therefore, optionally, in some embodiments, when the TDS value of the water in the waterway system is ≤1000 mg / L, it is determined that the water quality of the waterway system meets the preset conditions. Of course, other conditions can also be set for the preset conditions, which can be specifically set according to the actual situation and will not be elaborated here.

[0061] S102. When the water quality of the waterway system meets the preset conditions, trigger the waterway system to enter the recycling mode.

[0062] Among them, the recycling mode refers to the mode in which the waterway system is in the water recycling mode. In this mode, the utilization rate of water resources by the waterway system is higher than that in the purified water reflux mode. It can be understood that the waterway system can be triggered to enter the recycling mode manually or by the machine itself.

[0063] For example, when the water quality of the waterway system meets the preset conditions, a voice prompt can be broadcast or a prompt message can be pushed to the user's electronic device. After receiving the corresponding prompt, the user can manually turn on the recycling mode of the waterway system, such as controlling the waterway system to enter the recycling mode through an application program on the electronic device, or controlling the waterway system to enter the recycling mode through a physical button. It can be specifically set according to the actual situation and will not be elaborated here.

[0064] For another example, when the water quality of the water circuit system meets the preset conditions, the machine (referring to water purification equipment such as water purification devices) can generate a trigger command. Then, under the control of the trigger command, the water circuit system is controlled to enter the recovery mode.

[0065] S103. In the recovery mode, control the waste water return valve group and the waste water valve to work alternately.

[0066] In the recovery mode, the waste water return valve 603 and the waste water valve 602 are alternately opened. That is, when the waste water return valve 603 is opened, the waste water valve 602 is closed; when the waste water return valve 603 is closed, the waste water valve 602 is opened. Specifically, in the recovery mode, when the waste water return valve 603 is opened, the waste water valve 602 is closed. At this time, the water in the waste water circuit re-enters the position in front of the pump 204 through the waste water circuit, and under the pressure of the pump 204, it is filtered through the reverse osmosis filter element 202. Part of the water enters the pure water circuit through the reverse osmosis filter element 202, and the other part of the water enters the waste water circuit through the reverse osmosis filter element 202. Thus, when the water quality meets the preset conditions, the waste water return valve group and the waste water valve can be controlled to work alternately, thereby recovering water resources and avoiding waste of water resources. In the recovery mode, when the waste water valve 602 is opened, the waste water return valve is closed. During water production, the water source is filtered through the reverse osmosis filter element 202. Part of the water enters the pure water circuit through the reverse osmosis filter element 202, and the other part of the water is discharged after passing through the reverse osmosis filter element 202 and the waste water valve 602. Compared with simply opening and closing the waste water, the water in the membrane is always in a high-speed flowing state, and dead-end filtration will not occur, which is beneficial to extending the service life of the reverse osmosis filter element 202.

[0067] Furthermore, in the embodiments of the present application, by controlling the alternating working time corresponding to the recovery mode, the waste water return valve group 603 and the waste water valve 602 are controlled to work alternately. That is, optionally, in some embodiments, the step "In the recovery mode, control the waste water return valve group and the waste water valve to work alternately" may specifically include:

[0068] Determine the alternating working time corresponding to the recovery mode;

[0069] Based on the alternating working time, control the waste water return valve group and the waste water valve to work alternately.

[0070] It can be understood that in the embodiments of the present application, since different valves or valve groups are opened and closed at different times, when entering the recovery mode, it is necessary to determine the currently opened valve group and the currently closed valve group. Then, based on this, the waste water return valve group and the waste water valve are controlled to work alternately. That is, optionally, in some embodiments, the step "Based on the alternating working time, control the waste water return valve group and the waste water valve to work alternately" may specifically include:

[0071] Determine that the valve group opened at the current moment is the working valve group and the valve group closed at the current moment is the closed valve group;

[0072] Control the working valve group to work during the alternating working time and control the working valve group to close during the alternating working time;

[0073] After the alternating working time, update the working valve group to the closed valve group and update the closed valve group to the working valve group, and return to execute the step of determining that the valve group opened at the current moment is the working valve group and the valve group closed at the current moment is the closed valve group.

[0074] For example, specifically, when entering the recovery mode, a water purification device can determine that the valve group opened at the current moment is the working valve group and the valve group closed at the current moment is the closed valve group. Optionally, it can be preset that when entering the recovery mode, the waste water return valve group 603 is determined as the working valve group at the current moment and the waste water valve 602 is determined as the closed valve group at the current moment. Then, control the working valve group to work during the alternating working time and control the working valve group to close during the alternating working time. After the alternating working time, update the working valve group to the closed valve group and update the closed valve group to the working valve group, and return to execute the step of determining that the valve group opened at the current moment is the working valve group and the valve group closed at the current moment is the closed valve group, that is, determine the waste water valve 602 as the working valve group at the current moment and the waste water return valve group 603 as the closed valve group at the current moment. Thus, switch repeatedly until exiting the recovery mode. Of course, it can also be set that when entering the recovery mode, the waste water valve 602 is determined as the working valve group at the current moment and the waste water return valve group 603 is determined as the closed valve group at the current moment.

[0075] It should be noted that the alternating working time can be preset or set by the user. That is, optionally, in some embodiments, the step of "determining the alternating working time corresponding to the recovery mode" can specifically include:

[0076] Obtain the preset initial alternating time;

[0077] In response to the confirmation operation for the initial alternating time, determine the initial alternating time as the alternating working time corresponding to the recovery mode, or;

[0078] In response to the adjustment operation for the initial alternating time, determine the adjusted initial alternating time as the alternating working time corresponding to the recovery mode.

[0079] Among them, the initial alternating time can be 0 or a set duration. When the initial alternating time is 0, the user needs to manually set the alternating working time; when the initial alternating time is a set duration, the water purification device can directly determine this initial alternating time as the alternating working time corresponding to the recovery mode; or the user can determine this initial alternating time as the alternating working time corresponding to the recovery mode; of course, the user can also adjust this initial alternating time, and then determine the adjusted initial alternating time as the alternating working time corresponding to the recovery mode.

[0080] Optionally, in some embodiments, the control method of the present application may specifically further include:

[0081] Obtain the target flow ratio;

[0082] Adjust the alternating working time according to the target flow ratio.

[0083] Among them, the target flow ratio is the set water flow ratio of pure water to wastewater. Assume that in the purified water reflux mode, the ratio of pure water to wastewater is 1:1. Then, in the recovery mode, the ratio of pure water to wastewater can be 5:1 or 10:1, which can be specifically set according to the actual situation, that is, a target flow ratio can be output, and the alternating working time is adjusted according to the target flow ratio.

[0084] Optionally, in some embodiments, the control method of the present application may specifically further include: when the water quality of the water circuit system does not meet the preset conditions when the water circuit system is in the recovery mode, trigger the water circuit system to exit the recovery mode.

[0085] It can be understood that in the solution of the present application, cyclic opening and closing are adopted. The flux of the wastewater valve 602 and the wastewater return valve 3602 valve groups is relatively similar during the operation of the whole machine. Then, during cyclic opening and closing, the pressure fluctuation of the entire water circuit is small, and the pure water will not significantly vary greatly; in addition, on the premise of increasing the pure water recovery ratio, compared with simply opening and closing the wastewater valve 602, the pre-membrane pressure of the reverse osmosis filter element 202 and the water circuit pressure will not be too high or fluctuate suddenly, and the safety factor of the whole machine is higher.
