Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a method, system, water purifier and medium for adjusting minerals in a water purifier. Background Technology

[0002] As water purification products become increasingly popular, standalone purification functions are no longer sufficient to meet user needs. Users want purified water that is safe and retains minerals. Different groups have different requirements for the mineral content in water. Infants and the elderly need to supplement the body with more minerals and require water with a high concentration of mineral ions; young people, with better physical health and higher requirements for water taste, require water with a lower concentration of mineral ions.

[0003] Currently, mineralization can be used to address the above situation. However, mineralization filters pose safety risks, and they are often placed after membrane filters. Excessive mineralization can lead to high ion concentrations and bacterial growth. Alternatively, a mixing method can be used, which involves mixing water with different ion rejection rates to obtain a set TDS (Total Dissolved Solids) value. However, this method can only adjust the TDS value within a specific range.

[0004] Therefore, how to flexibly adjust the retention rates of divalent ions, mainly calcium and magnesium ions, and monovalent ions, mainly sodium and potassium ions, according to market demand is an urgent problem to be solved. Summary of the Invention

[0048] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0049] Example 1

[0050] The mineral adjustment method of the water purifier in this embodiment includes a first water purification system, a second water purification system, and a proportional adjustment system. Both the first and second water purification systems are connected to the proportional adjustment system. The second water purification system includes a pre-membrane ion concentration detection module, a first membrane filter, and a post-membrane ion concentration detection module. One end of the first membrane filter is connected to the pre-membrane ion concentration detection module, and the other end of the first membrane filter is connected to the post-membrane ion concentration detection module. The proportional adjustment system includes a mixing valve, such as... Figure 1 As shown, the mineral conditioning method includes:

[0051] S11. Detect the liquid water in the second water purification system using the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, obtain the corresponding first detection data and second detection data, and obtain the monovalent ion rejection rate and divalent ion rejection rate of the first membrane filter element.

[0052] S12. Calculate the target divalent ion contribution value based on the monovalent ion rejection rate, divalent ion rejection rate, first detection data, and second detection data.

[0053] S13. Calculate the mineral retention values ​​of monovalent ions and divalent ions based on the monovalent ion retention rate, divalent ion retention rate and the target divalent ion contribution value.

[0054] S14. Adjust the mixing valve based on the comparison result of the retention value of monovalent ion minerals or the retention value of divalent ion minerals with the set retention value, so that the first water purification system can achieve mineral regulation by circulating water in proportion.

[0055] In this embodiment, as Figure 2 As shown in the first structural diagram of the water purifier, the second water purification system includes a pre-filter, a power module, and a pre-membrane ion concentration detection module. Figure 2 The diagram shows the detection module 1), the first membrane filter element, and the post-membrane ion concentration detection module. Figure 2 (See Figure 2 for detection module).

[0056] Regarding steps S11-S14 above, assume that the first water purification system has no effect on removing mineral ions, for example, by using PP cotton, activated carbon, or ultrafiltration cartridges. If the liquid water in the second water purification system only contains divalent and monovalent ions, with divalent ions including calcium and magnesium ions, and monovalent ions including sodium and potassium ions.

[0057] In the second water purification system, the first membrane filter cartridge has a divalent ion rejection rate of 'a' and a monovalent ion rejection rate of 'b', where 'a' > 'b'. The percentages of ions passing through the first membrane filter cartridge are 1-a and 1-b, respectively. Taking a TDS sensor as an example, the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, if the pre-membrane ion concentration detection module obtains the first detection data T1 and the post-membrane ion concentration detection module obtains the second detection data T2, the target divalent ion contribution value is Tax = (T2 - T1 + T1 * b) / (ba). The divalent ion mineral retention value is Tax * (1 - a), and the monovalent ion mineral retention value is (T1 - Tax) * (1 - b), in mg / L. The monovalent ion mineral retention value or the divalent ion mineral retention value is selected as a reference point for mineral adjustment and compared with the set retention value to ensure that the first water purification system achieves mineral adjustment by proportionally circulating water. This method calculates the ion mineral retention value by detecting data before and after the first membrane filter in the second water purification system. The ratio adjustment system is then adjusted by comparing the ion mineral retention value with the set retention value to control the water flow of the first water purification system, thereby achieving automatic and flexible control of the mineral content according to the user's needs.

[0058] In one embodiment, step S14 specifically includes:

[0059] If the retention value of monovalent or divalent mineral ions is not less than the set retention value, adjust the mixing valve to control the first water purification system from flowing water.

[0060] If the retention value of divalent ion minerals is less than or equal to the set retention value, adjust the mixing valve to control the first water purification system to flow water according to the set ratio.

[0061] In this embodiment, it is determined whether the retention values ​​of monovalent and divalent mineral ions meet the requirements, and then the opening or closing of the mixing valve is controlled according to the comparison results. For example, if the retention value of divalent or monovalent mineral ions is 10, and the set retention value is 8, the mixing valve is closed so that the first water purification system does not flow, and all the water in the inlet pipe flows through the second water purification system for filtration, ultimately reducing the mineral retention value. Because the first water purification system has a low rejection rate and a high retention rate of mineral ions, while the second water purification system has a high rejection rate and a low retention rate of mineral ions, closing the mixing valve reduces the amount of liquid water flowing out of the first water purification system, which can effectively reduce the ion mineral retention value. If the retention value of divalent or monovalent mineral ions is 8, and the set retention value is 10, the mixing valve is opened so that the first water purification system flows water proportionally, and part of the water in the inlet pipe flows through the second water purification system for filtration, ultimately increasing the mineral retention value. Because the first water purification system has a low rejection rate and a high retention rate of mineral ions, while the second water purification system has a high rejection rate and a low retention rate of mineral ions, opening the mixing valve increases the amount of liquid water flowing out of the first water purification system, effectively increasing the ion mineral retention value.

[0062] In one embodiment, the proportional control system further includes a first flow meter and a second flow meter, the first flow meter being connected to a first water purification system and the second flow meter being connected to a second water purification system, such as... Figure 4 As shown, step S13 specifically includes:

[0063] S131. Collect corresponding first flow data and second flow data using the first flow meter and the second flow meter;

[0064] S132. Calculate the retention values ​​of monovalent and divalent minerals based on the monovalent ion retention rate, divalent ion retention rate, target divalent ion contribution value, first flow data, and second flow data.

[0065] In this embodiment, as Figure 3 As shown in the second structural diagram of the water purifier, the proportional adjustment system also includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the outlet pipe of the first water purification system, and the other end of the first flow meter is connected to the mixing valve. The second flow meter is connected to the outlet pipe of the second water purification system, and the other end of the second flow meter is connected to the mixing valve.

[0066] Regarding steps S131-S132 above, if the first flow meter and the second flow meter are used to collect the corresponding first flow data L1 and second flow data L2, the retention value of divalent ion minerals is: Tax*(1-a)*L2+Tax*L1 / (L1+L2), and the retention value of monovalent ion minerals is: (T1-Tax)*(1-b)*L2+(T1-Tax)*L1 / (L1+L2), with units of mg / L. It should be noted that the calculation formulas for the retention values ​​of monovalent and divalent ion minerals can be adaptively adjusted to improve the accuracy of mineral retention value calculation.

[0067] In one embodiment, the first water purification system includes a second membrane filter element, and the proportional control system further includes a first flow meter and a second flow meter, such as... Figure 5 As shown, step S13 specifically includes:

[0068] S131. Collect corresponding first flow data and second flow data using the first flow meter and the second flow meter;

[0069] S133. Obtain the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element;

[0070] S134. Based on the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element, calculate the monovalent ion mineral retention value and divalent ion mineral retention value, the target divalent ion contribution value, the first flow data and the second flow data.

[0071] In this embodiment, as Figure 3 As shown in the second structural schematic diagram of the water purifier, the proportional adjustment system also includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the outlet pipe of the first water purification system, and the other end of the first flow meter is connected to the mixing valve. The second flow meter is connected to the outlet pipe of the second water purification system, and the other end of the second flow meter is connected to the mixing valve. The first water purification system includes a second membrane filter element.

[0072] Regarding steps S131, S133, and S134 above, the second membrane filter element of the first water purification system has an ion retention effect. The divalent ion retention rate of the second membrane filter element is set as c, and the monovalent ion retention rate as d. The divalent ion retention rate is: (Tax*(1-a)*L2+Tax*(1-c)*L1) / (L1+L2), and the monovalent ion retention rate is: ((T1-Tax)*(1-b)*L2+(T1-Tax)*(1-d)*L1) / (L1+L2), with units of mg / L. It should be noted that the calculation formulas for the monovalent and divalent ion mineral retention values ​​can be adaptively adjusted to improve the accuracy of mineral retention value calculation.

[0073] This embodiment provides a method for adjusting the mineral content of a water purifier. The method calculates the ion mineral retention value by using the detection data before and after the first membrane filter in the second water purification system. The method then adjusts the ratio adjustment system by comparing the ion mineral retention value with the set retention value to control the water flow of the first water purification system. This allows for automatic adjustment of the mineral content according to user needs, thereby enhancing the user experience.

[0074] Example 2

[0075] The mineral regulation system of the water purifier in this embodiment includes a first water purification system, a second water purification system, and a proportional regulation system. Both the first and second water purification systems are connected to the proportional regulation system. The second water purification system includes a pre-membrane ion concentration detection module, a first membrane filter, and a post-membrane ion concentration detection module. One end of the first membrane filter is connected to the pre-membrane ion concentration detection module, and the other end is connected to the post-membrane ion concentration detection module. The proportional regulation system includes a mixing valve, such as... Figure 6 As shown, the mineral regulation system includes:

[0076] The detection module 310 is used to detect the liquid water in the second water purification system using the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, to obtain the corresponding first detection data and second detection data, and to obtain the monovalent ion rejection rate and divalent ion rejection rate of the first membrane filter element.

[0077] The first calculation module 320 is used to calculate the target divalent ion contribution value based on the monovalent ion rejection rate, the divalent ion rejection rate, the first detection data, and the second detection data.

[0078] The second calculation module 330 is used to calculate the mineral retention value of monovalent ions and the mineral retention value of divalent ions based on the monovalent ion retention rate, the divalent ion retention rate and the target divalent ion contribution value.

[0079] The adjustment module 340 is used to adjust the mixing valve based on the comparison result of the retention value of monovalent ion minerals or the retention value of divalent ion minerals with the set retention value, so that the first water purification system can achieve mineral regulation by circulating water in proportion.

[0080] In this embodiment, it is assumed that the first water purification system has no effect on removing mineral ions, for example, by using PP cotton, activated carbon, or ultrafiltration cartridges. The second water purification system contains only divalent and monovalent ions in its liquid water; the divalent ions include calcium and magnesium ions, and the monovalent ions include sodium and potassium ions.

[0081] In the second water purification system, the first membrane filter cartridge has a divalent ion rejection rate of 'a' and a monovalent ion rejection rate of 'b', where 'a' > 'b'. The percentages of ions passing through the first membrane filter cartridge are 1-a and 1-b, respectively. Taking a TDS sensor as an example, the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module calculate the target divalent ion contribution value as Tax = (T2 - T1 + T1 * b) / (ba) if the pre-membrane ion concentration detection module obtains the first detection data T1 and the post-membrane ion concentration detection module obtains the second detection data T2. The first calculation module 320 calculates the target divalent ion contribution value as Tax * (1-a) and the monovalent ion retention value as (T1 - Tax) * (1-b), in mg / L. The adjustment module 340 selects either the monovalent or divalent ion retention value as a reference point for mineral adjustment and compares it with the set retention value to ensure that the first water purification system achieves mineral adjustment by proportionally circulating water. This method calculates the ion mineral retention value by detecting data before and after the first membrane filter in the second water purification system. The ratio adjustment system is then adjusted by comparing the ion mineral retention value with the set retention value to control the water flow of the first water purification system, thereby achieving automatic and flexible control of the mineral content according to the user's needs.

[0082] like Figure 7 As shown, the adjustment module 340 includes:

[0083] The first regulating unit 341 is used to adjust the mixing valve to control the first water purification system from flowing water if the retention value of monovalent ion minerals or the retention value of divalent ion minerals is not less than the set retention value.

[0084] The second regulating unit 342 is used to adjust the mixing valve to control the first water purification system to flow water according to the set ratio if the retention value of monovalent ion minerals or the retention value of divalent ion minerals is less than the set retention value.

[0085] In this embodiment, it is determined whether the retention values ​​of monovalent and divalent ion minerals meet the requirements, and then the opening or closing of the mixing valve is controlled according to the comparison result. For example, if the retention value of divalent or monovalent ion minerals is 10, and the set retention value is 8, the first regulating unit 341 closes the mixing valve, causing the first water purification system to stop flowing water, and all the water in the inlet pipe flows through the second water purification system for filtration, ultimately reducing the retention value of minerals. Because the first water purification system has a low rejection rate and a high retention rate of mineral ions, while the second water purification system has a high rejection rate and a low retention rate of mineral ions, closing the mixing valve reduces the amount of liquid water flowing out of the first water purification system, effectively reducing the ion mineral retention value. If the retention value of divalent or monovalent ion minerals is 8, and the set retention value is 10, the second regulating unit 342 opens the mixing valve, causing the first water purification system to flow water proportionally, and part of the water in the inlet pipe flows through the second water purification system for filtration, ultimately increasing the retention value of minerals. Because the first water purification system has a low rejection rate and a high retention rate of mineral ions, while the second water purification system has a high rejection rate and a low retention rate of mineral ions, opening the mixing valve increases the amount of liquid water flowing out of the first water purification system, effectively increasing the ion mineral retention value.

[0086] In one embodiment, the proportional control system further includes a first flow meter and a second flow meter, the first flow meter being connected to a first water purification system and the second flow meter being connected to a second water purification system, such as... Figure 7 As shown, the second calculation module 330 includes:

[0087] The acquisition unit 331 is used to acquire corresponding first flow data and second flow data using the first flow meter and the second flow meter;

[0088] The first calculation unit 332 is used to calculate the retention value of monovalent ion minerals and the retention value of divalent ion minerals based on the monovalent ion retention rate, the divalent ion retention rate, the target divalent ion contribution value, the first flow data and the second flow data.

[0089] In this embodiment, the proportional adjustment system in the second structural diagram of the water purifier also includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the outlet pipe of the first water purification system, and the other end of the first flow meter is connected to the mixing valve. The second flow meter is connected to the outlet pipe of the second water purification system, and the other end of the second flow meter is connected to the mixing valve.

[0090] If the first flow meter and the second flow meter are used to collect the corresponding first flow data L1 and second flow data L2, the retention value of divalent ion minerals is: Tax*(1-a)*L2+Tax*L1 / (L1+L2), and the retention value of monovalent ion minerals is: (T1-Tax)*(1-b)*L2+(T1-Tax)*L1 / (L1+L2), with units of mg / L. It should be noted that the calculation formulas for the retention values ​​of monovalent and divalent ion minerals can be adaptively adjusted to improve the accuracy of mineral retention value calculation.

[0091] In one embodiment, the first water purification system includes a second membrane filter element, and the proportional control system further includes a first flow meter and a second flow meter. The first flow meter is connected to the first water purification system, and the second flow meter is connected to the second water purification system. The second calculation module 330 includes:

[0092] The acquisition unit 331 is used to acquire corresponding first flow data and second flow data using the first flow meter and the second flow meter;

[0093] The acquisition unit 333 is used to acquire the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element;

[0094] The second calculation unit 334 is used to calculate the mineral retention value of monovalent ions and the mineral retention value of divalent ions based on the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element, the monovalent ion rejection rate, the divalent ion rejection rate, the target divalent ion contribution value, the first flow data and the second flow data.

[0095] In this embodiment, the proportional adjustment system in the second structural schematic diagram of the water purifier further includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the outlet pipe of the first water purification system, and the other end of the first flow meter is connected to the mixing valve. The second flow meter is connected to the outlet pipe of the second water purification system, and the other end of the second flow meter is connected to the mixing valve. The first water purification system includes a second membrane filter element.

[0096] The second membrane filter element of the first water purification system has an ion retention effect. The divalent ion retention rate of the second membrane filter element is set as c, and the monovalent ion retention rate as d. The divalent ion retention rate is: (Tax*(1-a)*L2+Tax*(1-c)*L1) / (L1+L2), and the monovalent ion retention rate is: ((T1-Tax)*(1-b)*L2+(T1-Tax)*(1-d)*L1) / (L1+L2), with units of mg / L. It should be noted that the calculation formulas for the monovalent and divalent ion mineral retention values ​​can be adaptively adjusted to improve the accuracy of mineral retention value calculation.

[0097] This embodiment provides a mineral adjustment system for a water purifier. The second calculation module calculates the ion mineral retention value based on the detection data before and after the first membrane filter in the second water purification system. The adjustment module adjusts the ratio adjustment system by comparing the ion mineral retention value with the set retention value to control the water flow of the first water purification system, thereby automatically adjusting the mineral content according to user needs and enhancing the user experience.
