Description

[0002] With the increasing popularity of water purification products, the single water purification function can no longer meet the needs of users. Users hope that the purified water is safe and can retain the minerals in the water. Different people have different requirements for the mineral content in the water. Infants and the elderly need to supplement more minerals required by the human body, and the concentration of mineral ions in the water needs to be high; young people have high physical fitness and high requirements for the taste of the water quality, and the concentration of mineral ions in the water needs to be low.

[0003] At present, in response to the above situation, a mineralization scheme can be adopted to artificially add mineral ions. On the one hand, there are safety problems with the mineralization filter element. For example, heavy metal ions are precipitated. On the other hand, the mineralization filter element is usually arranged behind the membrane filter element, but excessive mineralization will lead to problems such as too high ion concentration and bacterial growth due to soaking; a water mixing scheme can also be adopted, and water with different ion rejection rates is used for water mixing operations to obtain water quality with a set TDS (Total dissolved solids) value, but only the TDS value within a specific range can be adjusted.

[0047] Embodiment 1

The water purification system and the mineralization system are both connected to one end of the proportion adjustment system, and the other end of the proportion adjustment system is connected to the detection system. The water purification system 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 proportion adjustment system includes a first mixing valve and a second mixing valve. The mineralization system includes a first mineralization filter element and a second mineralization filter element. The first mineralization filter element is connected to the first mixing valve, and the second mineralization filter element is connected to the second mixing valve. As Figure 1 shown, the mineral adjustment method includes:

[0049] S11. Use the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module to detect the liquid water in the water purification system, obtain the corresponding first detection data and second detection data, and obtain the third detection data by using the detection system;

[0050] S12. Obtain the monovalent ion rejection rate and divalent ion rejection rate of the membrane filter element;

[0051] S13. Calculate the divalent ion content and monovalent ion content in the water outlet pipeline based on the monovalent ion rejection rate, divalent ion rejection rate, first detection data, second detection data, and third detection data;

[0052] S14. Adjust the first mixing valve or the second mixing valve based on the comparison result between the divalent ion content or monovalent ion content and the set content to achieve purification water mineral adjustment.

[0053] In this embodiment, as Figure 2 shown, in the structural schematic diagram of the water purifier, the purification water system includes a pre-filter, a power module, a pre-membrane ion concentration detection module ( Figure 2 shown as detection module 1 in the figure), a membrane filter element, and a post-membrane ion concentration detection module ( Figure 2 shown as detection module 2 in the figure) and a post-filter. One end of the pre-filter is connected to the water inlet pipeline. The ratio adjustment system includes a first mixing valve ( Figure 2 shown as mixing valve 1 in the figure) and a second mixing valve ( Figure 2 shown as mixing valve 2 in the figure), and one end of the detection system is connected to the purified water pipeline.

[0054] For the above steps S11 - S14, if the liquid water in the purification water system 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. Set the rejection rate of the membrane filter element in the purification water system for divalent ions as a, and the rejection rate for monovalent ions as b, and a > b. The ion percentages passing through the membrane filter element are 1 - a and 1 - b respectively. Taking the TDS sensor as an example for 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, use the detection system to obtain the third detection data T3. Calculate the divalent ion content and monovalent ion content based on a, b, T1, T2, and T3. Select the monovalent ion mineral retention value or the divalent 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 content and the set retention value, and adjust the first mixing valve, or compare the difference between the divalent ion content and the set retention value, and adjust the second mixing valve. This method calculates the monovalent ion content and divalent ion content through the detection data before and after the membrane filter element in the purification water system and the detection data obtained by the detection system, and adjusts the first mixing valve or the second mixing valve of the ratio adjustment system according to the comparison result between the monovalent ion content and divalent ion content and the set retention value, further controlling the water flow rate of the first mineralization filter element or the second mineralization filter element to achieve automatic and flexible control of the mineral content based on user needs.

It should be noted that the calculation formulas of the target divalent ion contribution value and the monovalent or divalent ion mineral retention value can be adaptively adjusted to improve the accuracy of the calculation of the ion contribution value and the ion mineral retention value.

[0063] Exemplarily, the divalent ion content in the water purification pipeline is Tax * (1 - a) + (T3 - T2), and the monovalent ion content in the water purification pipeline is (T1 - Tax) * (1 - b) + (T3 - T2). Select the monovalent mineral retention value or the divalent mineral retention value as the calculation reference point for mineral adjustment. It should be noted that the calculation formulas of the monovalent ion content and the divalent ion content can be adaptively adjusted to improve the accuracy of the ion content calculation.

[0064] In one embodiment, the mineralization system further includes a first solenoid valve, a second solenoid valve, and a third solenoid valve. The first solenoid valve is connected to the first mineralization filter element, the second solenoid valve is connected to the second mineralization filter element, and both the first mixing valve and the second mixing valve are connected to the third solenoid valve. Step S14 specifically includes:

[0065] When adjusting the minerals for the monovalent ion content, close the second solenoid valve and open the third solenoid valve. When the monovalent ion content is not equal to the set content, adjust the first mixing valve;

[0066] When adjusting minerals for divalent ion content, close the first solenoid valve and open the third solenoid valve. When the divalent ion content is not equal to the set content, adjust the second mixing valve.

[0067] Exemplarily, when the user adjusts the monovalent ion content, if the calculated monovalent ion content is greater than the set content, adjust the first mixing valve to control the reduction of the water volume passing through the first mineralization filter element until it completely does not pass through the first mineralization filter element. When the user adjusts the divalent ion content, if the calculated divalent ion content is greater than the set content, adjust the second mixing valve to control the reduction of the water volume passing through the second mineralization filter element until it completely does not pass through the second mineralization filter element. This method controls the water flow rate of the first mineralization filter element or the second mineralization filter element according to the comparison results of the monovalent ion content and the divalent ion content with the set retention value, realizing automatic and flexible regulation of the monovalent or divalent mineral content based on user needs.

[0068] In this embodiment, a method for adjusting minerals of a water purifier is provided. The monovalent ion content and the divalent ion content are calculated through the detection data obtained by the water purification system and the detection data obtained by the detection system. According to the comparison results of the monovalent ion content and the divalent ion content with the set retention value, the first mixing valve or the second mixing valve is adjusted, and further the water flow rate of the first mineralization filter element or the second mineralization filter element is controlled, realizing automatic and flexible regulation of the mineral content based on user needs.

The ratio adjustment system includes a first mixing valve ( Figure 2 shown as mixing valve 1 in the figure), a second mixing valve ( Figure 2 shown as mixing valve 2 in the figure), and one end of the detection system is connected to the purified water pipeline.

[0076] If the liquid water in the water purification system 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. It is set that the rejection rate of the membrane filter element for divalent ions in the water purification system is a, and the rejection rate of monovalent ions is b, and a > b. The ion percentages passing through the membrane filter element are 1 - a and 1 - b respectively.
