[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] As described in the background section, when using reverse osmosis membranes to filter water sources in practice, complex pollutants such as calcium and magnesium salts, silicates, organic colloids, and microbial metabolites continuously accumulate on the concentrate side of the reverse osmosis membrane. The accumulation of these pollutants on the reverse osmosis membrane can not only induce scaling or blockage of the membrane pores, but may also lead to a significant decrease in the permeability (membrane flux) of the reverse osmosis membrane, thereby affecting the water purification effect.

[0032] In developing this invention, the applicant discovered that industrially, reverse osmosis membranes are periodically cleaned using electrolyzed water for alkaline and acid washing to remove surface contaminants and extend their lifespan. However, in household water purification systems, regularly performing alkaline and acid washing on the reverse osmosis membrane is challenging and requires precise control of the cleaning agent's pH value to prevent damage. Therefore, there is an urgent need to design a method for cleaning household water purification systems using electrolyzed water, thereby cleaning the reverse osmosis membrane, maintaining its purification performance, and extending its lifespan.

[0033] The control method of the water purification equipment according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] The water purification device provided in this embodiment of the invention includes a filter module and an electrolysis module. The filter module can be a reverse osmosis membrane, used to filter and purify the raw water input to the water purification device. The electrolysis module is used to electrolyze water to further generate electrolyzed water with different acidity / alkalinity, and the generated electrolyzed water is used to clean the filter module. The electrolysis module includes a first outlet and a second outlet, wherein the first outlet is the target outlet, which can be connected to the filter module through a pipeline to deliver the target acid / alkaline electrolyzed water to the filter module.

[0035] refer to Figure 1 This is a flowchart of a control method for a water purification device provided in an embodiment of the present invention.

[0036] Step S101: Obtain the total dirt level of the filter module;

[0037] Specifically, before cleaning the filter module of the water purification equipment, it is necessary to first obtain the total dirt value of the filter module, which represents the dirt status of the filter module at the current moment.

[0038] Specifically, TDS (Total Dissolved Solids) is an indicator that measures the total amount of dissolved solids in water. It is used to indicate how many milligrams of minerals, salts, and other non-organic substances are dissolved in 1 liter of water. The unit is ppm (mg / L). TDS can be used as one of the indicators for preliminary judgment of whether water quality is suitable for drinking. The higher the TDS value, the more dissolved solids there are in the raw water, and the more impurities there are in the raw water.

[0039] The contamination value can be defined as A, with units of ppm·s. Based on the TDS value of the raw water, the contamination value can be divided into three levels, and the calculation model formula is as follows:

[0040]

[0041] Where T is the TDS value of the raw water, in ppm; a0, a1, and a2 are adjustment coefficients.

[0042] As can be seen from the above dirt value formula, the higher the TDS value of the raw water, the higher the dirt value of the filter module.

[0043] refer to Figure 2 This is a flowchart for obtaining the total dirt value of the filter module according to an embodiment of the present invention.

[0044] Step S201: When the water purification equipment is in the water output state, the TDS value of the raw water is obtained every second preset time interval.

[0045] Specifically, since the TDS value of the raw water may fluctuate at any given time when the water purification equipment is in the outlet state, in order to reduce the amount of TDS data to be acquired while still being able to approximate the calculation of dirt value by integration, the TDS value can be acquired at regular intervals, and the integration can be converted into discrete accumulation. That is, the TDS value of the raw water is acquired every second preset time interval, where the second preset time interval can be a relatively short period of time, such as 100ms. The accumulation formula per unit time can be:

[0046]

[0047] Where n is the number of times the TDS value of the raw water is obtained; T n This represents the TDS value of the raw water obtained in the nth iteration.

[0048] Among them, when T n When ≤100, a=a0; when 100 <T n When T ≤ 300, a = a1; when T n When the value is greater than 300, a = a2.

[0049] In addition, obtaining TDS values ​​at intervals is beneficial to the accuracy of total dirt value calculation. For example, if the TDS value obtained at a certain moment when the water purification equipment is in the water output state is used as the representative value of the TDS value in that time period, the TDS value of the raw water may fluctuate during the flow process, which may lead to a large error in the calculation value.

[0050] Step S202: Determine the current dirt value based on the TDS value and the second preset duration.

[0051] Specifically, based on the TDS value obtained at the current moment and the second preset time interval, the dirt content in the raw water within the current second preset time interval can be determined.

[0052] refer to Figure 3 This is a flowchart for determining the current dirt value provided in an embodiment of the present invention.

[0053] Step S301: Determine the adjustment coefficient based on the TDS value;

[0054] Specifically, before determining the current dirt value, a specific coefficient value can be obtained through repeated experiments: based on the fact that different raw water TDS values ​​produce the same total dirt value over a period of time, the coefficient under different TDS levels can be further determined.

[0055] The following specific examples illustrate how to determine the adjustment coefficient based on the TDS value:

[0056] Assume the actual experimental data are as shown in Table 1:

[0057] Table 1

[0058] 100 12000 200 9000 400 5000

[0059] Define the coefficient a0 as 1 at this point, and we can further determine that the total dirt value at this point is:

[0060]

[0061] in, A0 is the dirt value per unit time corresponding to coefficient a0; A0 is the dirt value per time period corresponding to coefficient a0.

[0062] Furthermore, coefficients a1 and a2 are calculated based on the total dirt value.

[0063]

[0064] The calculated value of a1 is 0.667.

[0065]

[0066] The calculated value of a2 is 0.6.

[0067] After calculating the adjustment coefficient, input the adjustment coefficient into the calculation model.

[0068] It should be noted that, in this embodiment of the invention, when calculating the dirt value, it is only necessary to determine the ratio of coefficients a0, a1, and a2.

[0069] Step S302: The product of the adjustment coefficient, the TDS value, and the second preset duration is used as the current dirt value.

[0070] Specifically, the current dirt value is calculated based on the adjustment coefficient, TDS value, and second preset duration. For example, if the second preset duration is 100ms, the current TDS value is 120, and the adjustment coefficient a0 is 0.8, the current dirt value is: A = a0 * T * t = 0.1 * 120 * 0.8 = 9.6.

[0071] Step S203: The current dirt value is accumulated to determine the total dirt value.

[0072] Specifically, the obtained current dirt values ​​are summed to determine the total dirt value. For example, assuming the adjustment coefficients a0 are 0.8, a1 is 0.6, and a2 is 0.5, and the obtained raw water TDS values ​​and corresponding effluent times are: T0 = 100, t0 = 2000; T1 = 150, t1 = 1500; T2 = 200, t2 = 1000, the total dirt value is further calculated as follows:

[0073] A=a0*T0*t0+a1*T1*t1+a2*T2*t2

[0074] A=0.8*100*2000+0.6*150*1500+0.5*200*1000

[0075] A = 395000

[0076] Step S102: When the total dirt value is greater than the preset dirt value, control the electrolysis module to run for a first preset time to generate cleaning water to clean the filter module.

[0077] Specifically, when the calculated total dirt value of the filter module is greater than the preset dirt value, it indicates that the filter module is seriously dirty, which may affect the quality of the effluent. It is necessary to control the electrolysis module to run for a first preset time to generate cleaning water to clean the filter module. The first preset time is the total cleaning time.

[0078] It should be noted that the cleaning of the filter module can be set to be performed when the device is in standby mode, such as preferably during the early morning hours when the probability of users drawing water is low, to ensure that the water quality of the device is not affected and to further protect the health of users' drinking water.

[0079] As an optional embodiment, controlling the electrolysis module to run for a first preset duration includes: controlling the electrolysis module to run with a first current for a third preset duration, and / or controlling the electrolysis module to run with a second current for a fourth preset duration, wherein the direction of the first current is opposite to the direction of the second current, and both the third preset duration and the fourth preset duration are less than or equal to the first preset duration.

[0080] Specifically, when the electrolysis module is running, it produces acidic electrolyzed water and alkaline electrolyzed water. When the electrolysis module is running with a first current, acidic electrolyzed water is produced at the first outlet of the electrolysis module; when the electrolysis module is running with a second current, acidic electrolyzed water is produced at the first outlet of the electrolysis module.

[0081] The water purification equipment can control the operation of the electrolysis module according to the specific dirt level of the filter module, as follows:

[0082] When the electrolysis module operates at the first current for a third preset time to generate acidic electrolyzed water, and only the acidic electrolyzed water is used to clean the filter module, the third preset time is equal to the first preset time. When the electrolysis module operates at the second current for a fourth preset time to generate alkaline electrolyzed water, and only the alkaline electrolyzed water is used to clean the filter module, the fourth preset time is equal to the first preset time. When the electrolysis module operates at the first current for a third preset time to generate acidic electrolyzed water, and also operates at the second current for a fourth preset time to generate alkaline electrolyzed water, the order in which the electrolysis module is controlled by the first current and the second current can be interchanged. In this case, both the third preset time and the fourth preset time are less than the first preset time, and the sum of the third preset time and the fourth preset time is equal to the first preset time.

[0083] It should be noted that the control mode of the electrolysis module, depending on the degree of dirtiness of the filter module, includes but is not limited to the above embodiments. The operating mode, time, and frequency need to be adjusted according to the actual situation to ensure that the filter module can be thoroughly cleaned.

[0084] refer to Figure 4 This is a schematic diagram of the structure of the water purification equipment provided in an embodiment of the present invention.

[0085] As an optional embodiment, the water purification device also includes a water storage tank, the inlet of which is connected to the second outlet of the electrolysis module.

[0086] Specifically, the second outlet can be connected to a water storage tank to store non-target electrolyzed water generated by the electrolysis module for other uses. For example, if an abnormal pH level is detected after cleaning the filter module, the stored electrolyzed water can be used to adjust the abnormality.

[0087] As an optional embodiment, the filter module includes a water outlet and a wastewater outlet, and a wastewater valve is installed on the wastewater pipeline connected to the wastewater outlet. The control method further includes: controlling the wastewater valve to be in the open state when cleaning the filter module.

[0088] Specifically, the filter module includes a water outlet and a wastewater outlet, wherein a wastewater valve is installed on the wastewater pipeline connected to the wastewater outlet.

[0089] When providing drinking water to users normally, the wastewater valve is de-energized and closed to prevent filtered drinking water from flowing into the wastewater pipe and wasting resources. After passing through the filter module, the raw water flows to the water intake through the filter outlet, providing users with filtered and purified drinking water that can be directly consumed. When cleaning the filter module, the wastewater valve is energized and opened. After the electrolyzed water cleans the filter module, it flows into the wastewater pipe through the wastewater outlet, and the cleaned electrolyzed water is then discharged.

[0090] refer to Figure 5 This is a logic diagram of the control method for the water purification equipment provided in the embodiments of the present invention.

[0091] Specifically, when the water purification equipment is in the water output state, the TDS value of the raw water is obtained, the dirt value of the filter module is calculated, and the total dirt value of the filter module is calculated based on the obtained dirt value. It is then determined whether the total dirt value is greater than the preset dirt value: if the total dirt value is greater than the preset dirt value, it means that the filter module needs to be cleaned. When the water purification equipment is in the standby state, current is input to the electrolysis module to generate electrolyzed water, and the filter module is cleaned for a preset time; if the total dirt value is not greater than the preset dirt value, it means that the filter module does not need to be cleaned temporarily. The dirt value of the filter module can be obtained again when the water purification equipment is in the water output state, until the total dirt value of the filter module is greater than the preset dirt value, at which point the filter module is cleaned.

[0092] As an optional embodiment, the second outlet of the electrolysis module is connected to the wastewater pipeline.

[0093] Specifically, the second outlet of the electrolysis module is connected to the wastewater pipeline, which can discharge the non-target electrolyzed water produced by the electrolysis module.

[0094] As an optional embodiment, the water purification equipment also includes a one-inlet-two-outlet valve, a first branch, a second branch, and a booster pump. The first outlet of the one-inlet-two-outlet valve is connected to the inlet of the first branch, the second outlet of the one-inlet-two-outlet valve is connected to the inlet of the second branch, the outlets of the first branch and the second branch merge and are connected to the inlet of the booster pump, the outlet of the booster pump is connected to the inlet of the filter module, and the electrolysis module is located on the second branch.

[0095] It should be noted that booster pumps are used to increase the water pressure in the equipment pipeline, so that the water can flow more quickly in the equipment pipeline.

[0096] Specifically, the water purification equipment also includes a one-inlet-two-outlet valve. The first outlet of the one-inlet-two-outlet valve is connected to one end of the first branch, and the second outlet of the one-inlet-two-outlet valve is connected to one end of the second branch. An electrolysis module is installed on the second branch. The other end of the first branch and the other end of the second branch merge and are further connected to a booster pump. The outlet of the booster pump is connected to the inlet of the filter module.

[0097] A one-in-two-out valve is used to switch the water flow direction of the water purification equipment according to its operating mode.

[0098] Specifically, when the water purification equipment is purifying water, the second outlet of the one-in-two-out valve is closed, while the first outlet and the booster pump are open. At this time, the raw water flows through the first branch and then to the booster pump. The booster pump quickly supplies the raw water to the filter module. After filtration and purification, the water flows through the filter module's outlet to the water intake for user use.

[0099] When the total dirt value exceeds the preset dirt value, the water purification equipment cleans the filter module. The first outlet of the one-in-two-outlet valve is closed while the second outlet is open. At this time, the raw water flows through the electrolysis module to generate electrolyzed water. The target electrolyzed water generated by the electrolysis module flows through the first outlet of the electrolysis module to the pipeline where the booster pump is located, and then flows to the filter module to clean the filter module. The wastewater flows through the wastewater outlet of the filter module to the wastewater pipeline, and the cleaned electrolyzed water is discharged from the wastewater pipeline. The non-target electrolyzed water generated by the electrolysis module flows through the second outlet of the electrolysis module to the wastewater pipeline or the storage tank, and is discharged from the wastewater pipeline or stored in the storage tank for other uses.

[0100] As an optional embodiment, the water purification equipment can also be equipped with a purification module on its inlet pipe. This purification module can be a multi-stage purification device, which may include a PP cotton filter: for coarse filtration of the water flow, effectively intercepting large suspended particles such as sediment and rust; an activated carbon filter: removing residual chlorine, discoloration, odor, and some organic pollutants through physical adsorption and chemical catalysis; and a precision filter membrane or ultrafiltration membrane: further retaining microorganisms, colloids, and other minute impurities. Furthermore, for areas with hard water, the purification module can also include an ion exchange resin filter to reduce the concentration of calcium and magnesium ions in the water flow, effectively preventing scaling on the electrolysis module. By incorporating the purification module, the electrodes of the electrolysis module can be protected from corrosion by impurities. In addition, the purified water has a more stable conductivity, significantly improving electrolysis efficiency.

[0101] It should be noted that the purification module can also be installed between the filter module's water outlet and the water inlet to further purify the water passing through the filter module, thereby ensuring the safety and health of the drinking water obtained by the user.

[0102] The control method for water purification equipment provided by the present invention can, while purifying and filtering water sources for users, calculate the degree of dirtiness of the filter module based on the TDS value of the water source, and further control the electrolysis module to generate corresponding electrolyzed water to clean the filter module according to the degree of dirtiness of the filter module. This achieves intelligent cleaning of the filter module, effectively extends the service life of the filter module, further ensures the water purification effect of the water purification equipment, and protects the health of users' drinking water.

[0103] Based on the same inventive concept, corresponding to the control method of the water purification device in any of the above embodiments, this application also provides a computer-readable storage medium that stores computer instructions for causing a computer to execute the control method of the water purification device in any of the above embodiments.

For the purposes of this specification, "computer-readable medium" can be any means that can contain, store, communicate, propagate, or transmit programs for use by, or in conjunction with, an instruction execution system, apparatus, or device.

Furthermore, computer-readable media can even be paper or other suitable media on which programs can be printed, because programs can be obtained electronically, for example, by optically scanning the paper or other media, followed by editing, interpreting, or otherwise processing as necessary, and then stored in computer memory.

[0106] The computer instructions stored in the computer-readable storage medium of the above embodiments are used to cause a computer to execute the control method of the water purification device in any of the above exemplary method sections. The control method of the water purification device can calculate the degree of dirtiness of the filter module based on the TDS value of the water source while purifying and filtering the water source and providing it to the user. Furthermore, it controls the electrolysis module to generate corresponding electrolyzed water to clean the filter module based on the degree of dirtiness of the filter module. This achieves intelligent cleaning of the filter module, effectively extends the service life of the filter module, further ensures the water purification effect of the water purification device, and protects the user's drinking water health.

[0107] refer to Figure 6 This is a schematic diagram of the control device 600 of the water purification equipment provided in an embodiment of the present invention.
