[0040] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0041] Embodiment 1

[0042] For the mineral adjustment method of the water purifier in this embodiment, the water purifier includes a purified water passage and a wastewater passage. The purified water passage includes a pre-membrane ion concentration detection module, a membrane filter element, and a post-membrane ion concentration detection module. One end of the membrane filter element is connected to the pre-membrane ion concentration detection module, and the other end of the membrane filter element is connected to the post-membrane ion concentration detection module. The wastewater passage includes an adjustable wastewater solenoid valve. As Figure 1 shown, this mineral adjustment method includes:

[0043] S11. Use the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module to detect the liquid water in the purified water passage, and obtain the corresponding first detection data and second detection data;

[0044] S12. Obtain the current monovalent ion rejection rate and the current divalent ion rejection rate of the membrane filter element corresponding to the current adjustable wastewater ratio gear of the adjustable wastewater solenoid valve;

[0045] S13. Calculate the divalent ion mineral retention value and the monovalent ion mineral retention value in the purified water according to the current monovalent ion rejection rate, the current divalent ion rejection rate, the first detection data, and the second detection data;

[0046] S14. Adjust the current adjustable wastewater ratio gear of the adjustable wastewater solenoid valve based on the comparison result between the divalent ion mineral retention value or the monovalent ion mineral retention value and the set retention value, so that the wastewater passage discharges water in proportion to achieve mineral adjustment.

[0047] In this embodiment, the water purifier includes a purified water passage and a wastewater passage. The purified water passage includes a pre-filter, a power module, a pre-membrane ion concentration detection module ( Figure 2 shown as detection module 1 in Figure 2 ), a membrane filter element, a post-membrane ion concentration detection module ( shown as detection module 2 in ) and a post-filter.

[0048] For the above steps S11 - S14, if the liquid water in the purified water passage only includes divalent ions and monovalent ions, the divalent ions include calcium ions and magnesium ions, and the monovalent ions include sodium ions and potassium ions. Obtain the current divalent ion rejection rate an of the membrane filter element corresponding to the current adjustable wastewater ratio gear n of the adjustable wastewater solenoid valve, the current monovalent ion rejection rate is bn, and an > bn. The ion percentages passing through the membrane filter element are 1 - an and 1 - bn respectively. The pre - membrane ion concentration detection module and the post - membrane ion concentration detection module take the TDS sensor as an example. 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. Calculate the divalent ion mineral retention value and the monovalent ion mineral retention value in the purified water based on an, bn, T1, and T2.

[0049] It is preset that under the preset adjustable wastewater ratio gear, the contribution value of divalent ions Tax = (T2 - T1 + T1 * bn) / (bn - an), the divalent ion mineral retention value is: Tax * (1 - an), and the monovalent ion mineral retention value is: (T1 - Tax) * (1 - bn), with the unit of mg / L. Select either the divalent ion mineral retention value or the monovalent ion mineral retention value as the calculation reference point for mineral adjustment, obtain the set retention value of minerals in the purified water pipeline, compare the difference between the monovalent ion mineral retention value and the set retention value, and adjust the current adjustable wastewater ratio gear, or compare the difference between the monovalent ion mineral retention value and the set retention value, and adjust the current adjustable wastewater ratio gear. This method integrates the purified water passage and the wastewater passage. By comparing the ion mineral retention value in the purified water passage with the set retention value, the adjustable wastewater solenoid valve in the wastewater passage is adjusted in reverse, controlling the wastewater passage to flow water according to a ratio, and realizing the automatic and flexible regulation of the mineral content based on user needs.

[0050] In one embodiment, the ion rejection rate of the membrane filter element corresponding to the adjustable wastewater solenoid valve at the high gear is greater than that of the membrane filter element corresponding to the adjustable wastewater solenoid valve at the low gear.

[0051] Specifically, the current adjustable wastewater ratio gear is n, the current divalent ion rejection rate is an, the current monovalent ion rejection rate is bn, where n is a natural number greater than or equal to 1, and the actual gear data can be designed according to requirements. And it is set that the larger n is, the higher the wastewater ratio of the wastewater passage is, a7 > a1, and b7 > b1.

[0052] In one embodiment, step S14 specifically includes:

[0053] If the monovalent ion mineral retention value or the divalent ion mineral retention value is not greater than the set retention value, lower the current adjustable wastewater ratio gear of the adjustable wastewater solenoid valve by one gear to control the reduction of the water flow volume in the wastewater passage;

[0054] If the retention value of monovalent ion minerals or the retention value of divalent ion minerals is greater than the set retention value, the current adjustable wastewater ratio gear of the adjustable wastewater solenoid valve is increased by one gear to control the increase in the water flow rate of the wastewater passage; wherein, the number of gears decreased by one gear is less than the number of gears increased by one gear.

[0055] Exemplarily, if the retention value of monovalent ion minerals or the retention value of divalent ion minerals is less than the set retention value, the adjustable wastewater solenoid valve is increased by one gear to control the reduction of the flow rate of the wastewater passage, and it is determined to take water using the increased gear, and the current adjustable wastewater ratio gear for taking water is determined as the initial adjustable wastewater ratio gear for taking purified water at the set value next time. If the retention value of monovalent ion minerals or the retention value of divalent ion minerals is greater than the set retention value, the adjustable wastewater solenoid valve is increased by one gear, n is increased by 1, the wastewater proportion is higher, and the rejection rate of the membrane filter element is improved. It is calculated whether the retention value of minerals at the current adjustable wastewater ratio gear is closer to the set retention value according to the calculation formula of the retention value of divalent ion minerals or monovalent ion minerals.

[0056] In one embodiment, as Figure 3 shown, step S12 specifically includes:

[0057] S121. Pre-build the corresponding relationship between the adjustable wastewater ratio gears of different adjustable wastewater solenoid valves and the monovalent ion rejection rate and divalent ion rejection rate of the membrane filter element;

[0058] S122. Screen out the current monovalent ion rejection rate and current divalent ion rejection rate corresponding to the current adjustable wastewater ratio gear of the adjustable wastewater solenoid valve from the corresponding relationship.

[0059] For the membrane filter element of the preset purified water passage under different gears of the adjustable wastewater ratio, the divalent ion rejection rate is an, the monovalent ion rejection rate is bn, an > bn, and n is a natural number greater than or equal to 1. According to the adjustable wastewater ratio gear, an and bn, the corresponding relationship is constructed, and the current monovalent ion rejection rate b1 and current divalent ion rejection rate a1 corresponding to the current adjustable wastewater ratio gear 1 can be screened out from the corresponding relationship. It should be noted that the number of gears of the adjustable wastewater ratio can be adjusted according to the actual situation to improve the control accuracy of the retention value of minerals.

[0060] In this embodiment, a method for adjusting minerals of a water purifier is provided. By integrating the purified water passage and the wastewater passage, the adjustable wastewater solenoid valve of the wastewater passage is reversely adjusted according to the comparison result between the ion mineral retention value in the purified water passage and the set retention value, and the wastewater passage is controlled to pass water in proportion, so as to realize the automatic and flexible regulation of the mineral content based on user needs.

[0068] shown as detection module 2 in

[0069] ), and a post-filter. If the liquid water in the purified water passage only includes divalent ions and monovalent ions, the divalent ions include calcium ions and magnesium ions, and the monovalent ions include sodium ions and potassium ions. The current divalent ion rejection rate of the membrane filter element corresponding to the current adjustable wastewater ratio gear n of the adjustable wastewater solenoid valve is an, and the current monovalent ion rejection rate is bn, and an > bn. The ion percentages passing through the membrane filter element are 1 - an and 1 - bn respectively. The pre-membrane ion concentration detection module and the post-membrane ion concentration detection module take the TDS sensor as an example. 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 divalent ion mineral retention value and the monovalent ion mineral retention value in the purified water are calculated based on an, bn, T1, and T2.When preset at the preset gear of the adjustable wastewater ratio, the contribution value of divalent ions Tax = (T2 - T1 + T1 * bn)) / (bn - an), and the retention value of divalent ion minerals is: Tax * (1 - an), and the retention value of monovalent ion minerals is: (T1 - Tax) * (1 - bn), with the unit of mg / L. Select the retention value of divalent ion minerals or the retention value of monovalent ion minerals as the calculation reference point for mineral adjustment, obtain the set retention value of minerals in the purified water pipeline, compare the difference between the retention value of monovalent ion minerals and the set retention value, and adjust the current adjustable wastewater ratio gear, or compare the difference between the retention value of monovalent ion minerals and the set retention value, and adjust the current adjustable wastewater ratio gear. This method integrates the purified water path and the wastewater path, and reversely adjusts the adjustable wastewater solenoid valve of the wastewater path according to the comparison result between the ion mineral retention value in the purified water path and the set retention value, controls the wastewater path to pass water according to a ratio, and realizes the automatic and flexible regulation of the mineral content based on user needs.

[0070] In one embodiment, the ion rejection rate of the membrane filter element corresponding to the adjustable wastewater solenoid valve at the high gear is greater than the ion rejection rate of the membrane filter element corresponding to the adjustable wastewater solenoid valve at the low gear.

[0071] Specifically, the current adjustable wastewater ratio gear is n, the current divalent ion rejection rate is an, the current monovalent ion rejection rate is bn, where n is a natural number greater than or equal to 1, and the actual gear data can be designed according to requirements. And it is set that the larger n is, the higher the wastewater ratio of the wastewater path is, a7 is greater than a1, and b7 is greater than b1.
