[0002] As people's living standards improve, the demand for purified and softened water is increasing. For example, soft water is used for washing in areas with high hardness, while purified water is used for drinking and cleaning. Commercially available household water softening products often use softening resins to soften the water, and then regenerate it by adding salt at set intervals or after a set water usage. Different users have different water quality conditions, resulting in varying concentrations of calcium and magnesium ions in the water.

[0003] When the concentration of calcium and magnesium ions in the water is low, the resin needs to be regenerated, and the resin in the water softener module is not ineffective, the cycle water production rate should be increased; when the concentration of calcium and magnesium ions in the water is high and the set regeneration time has not yet arrived, but the resin has already ineffective, the cycle water production rate should be reduced.

[0004] Therefore, how to dynamically adjust the cycle water production of a water softener according to the calcium and magnesium ion concentrations of different water qualities is an urgent problem to be solved. Summary of the Invention

[0041] 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.

[0042] Example 1

[0043] This embodiment describes a method for calculating the cycle water production of a water purifier / softener. The water purifier / softener includes a softening system and a purification system. The purification system includes a pre-membrane ion concentration detection module, a membrane filter cartridge, and a post-membrane ion concentration detection module. One end of the membrane filter cartridge is connected to the pre-membrane ion concentration detection module, and the other end is connected to the post-membrane ion concentration detection module. Figure 1 As shown, the calculation method includes:

[0044] S11. Detect the liquid water in the water purification system using the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, and obtain the corresponding first detection data and second detection data.

[0045] S12. Obtain the cycle water production rate and the ion rejection rate of the membrane filter element; the cycle water production rate is used to characterize the maximum water consumption that the soft water system can handle within a single regeneration cycle;

[0046] S13. Calculate the target divalent ion contribution value based on the ion rejection rate, the first detection data, and the second detection data.

[0047] S14. Determine the target adjustment coefficient based on the target divalent ion contribution value, and update the cycle water production based on the target adjustment coefficient.

[0048] In this embodiment, as Figure 2As shown in the schematic diagram of the water purifier, the water softening system includes at least a water softening module, a water metering module, and a control module. The water purification system includes a pre-filter 2, a power module, a pre-membrane ion concentration detection module (shown as detection module 1 in the figure), a membrane filter, a post-membrane ion concentration detection module (shown as detection module 2 in the figure), and a post-filter. One end of the pre-filter 2 is connected to one end of the power module, and the other end of the pre-filter 2 is connected to the pre-filter 1. One end of the pre-membrane ion concentration detection module 1 is connected to the power module, and the other end of the pre-membrane ion concentration detection module 1 is connected to the membrane filter. One end of the post-membrane ion concentration detection module 2 is connected to the membrane filter, and the other end of the post-membrane ion concentration detection module 2 is connected to the post-filter. The control module executes the above algorithm steps.

[0049] Regarding steps S11-S14 above, if the liquid water in the water purification system contains only divalent and monovalent ions, with divalent ions including calcium and magnesium ions, and monovalent ions including sodium and potassium ions, the divalent ion rejection rate and monovalent ion rejection rate can be determined through testing based on the performance of the membrane filter cartridge. The target divalent ion contribution value is calculated using the divalent ion rejection rate, monovalent ion rejection rate, first detection data, and second detection data. The corresponding target adjustment coefficient is determined by looking up the target divalent ion contribution value in a table. The updated cycle water production rate is obtained by mathematically calculating the divalent ion contribution value in the water based on the purification effect of the water purification system, and then automatically and dynamically adjusts the cycle water production rate of the softening system based on the target adjustment coefficient to avoid wasting liquid water and salt, and to enhance the water softening effect.

[0050] Specifically, step S13 includes:

[0051] The contribution value of divalent ions is calculated based on the first detection data, the second detection data, the divalent ion rejection rate, and the monovalent ion rejection rate.

[0052] For example, if the liquid water in the water purification system contains only monovalent and divalent ions, and the first detection data is T1 mg / L, the second detection data is T2 mg / L, and the divalent ion rejection rate of the water purifier is 'a', the monovalent ion rejection rate is 'b', and a > b, then the divalent ion pass-through rate through the membrane filter is 1 - a, and the monovalent ion pass-through rate is 1 - b. The formula for calculating the target divalent ion contribution value is Tax = (T2 - T1 + T1 * b) / (ba). If T2 is 100 (mg / L), T1 is 350 (mg / L), a is 90%, and b is 60%, then Tax = 133.3 mg / L.

[0053] In one embodiment, step S14 specifically includes:

[0054] S141. Pre-construct the correspondence between the contribution values ​​of divalent ions and the adjustment coefficients in different ranges;

[0055] S142. Select the target adjustment coefficient corresponding to the contribution value of the target divalent ion from the correspondence.

[0056] In this embodiment, a correspondence between adjustment coefficients kx1, kx2, kx3, and kx4 is pre-constructed based on experimental data when Tax is in several different ranges such as [0.100], [100.200], [200.300], and [300.400]. The target adjustment system corresponding to the range of the target divalent ion contribution value is then selected from this correspondence. The set range of the divalent ion contribution value in this calculation method can be adjusted according to the product requirements of the water purifier / softener, with a base range of 50 mg / L for level adjustment.

[0057] In one embodiment, step S14 specifically includes:

[0058] S143. Determine the preset reference value for the contribution of divalent ions;

[0059] S144. Calculate the target adjustment coefficient based on the reference value of divalent ion contribution and the target divalent ion contribution.

[0060] In this embodiment, a preset reference value for the divalent ion contribution is T0, and the ratio of the reference value T0 to the target divalent ion contribution value Tax is used as the target adjustment coefficient kx. T0 is set to 200 mg / L. When Tax is 200 mg / L, the target adjustment coefficient kx equals 1; when Tax is greater than 200 mg / L, the target adjustment coefficient kx is less than 1; and when Tax is less than 200 mg / L, the target adjustment coefficient kx is greater than 1. It should be noted that the product of the ratio of the divalent ion contribution reference value T0 to the target divalent ion contribution value Tax and a preset proportionality coefficient can also be used as the target adjustment coefficient kx to improve the flexibility of the target adjustment coefficient calculation method.

[0061] This embodiment provides a method for calculating the periodic water production of a water purifier / softener. This method integrates water softening and water purification functions, calculates the contribution value of divalent ions in the water by reverse calculation based on the purification effect of the water purification system, and then calculates the target adjustment coefficient based on the contribution value of divalent ions. This automatically and intelligently adjusts the periodic water production of the softening system, avoiding waste of liquid water and salt, and improving the softening effect.

[0062] Example 2

[0063] The water purifier / softener in this embodiment has a system for calculating the periodic water production. This system includes a soft water system and a purification system. The purification system includes a pre-membrane ion concentration detection module, a membrane filter, and a post-membrane ion concentration detection module. One end of the 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. Figure 3 As shown, the computing system includes:

[0064] The detection module 310 is used to detect the liquid water in the water purification system using the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, and to obtain the corresponding first detection data and second detection data.

[0065] The acquisition module 320 is used to acquire the cycle water production and the ion rejection rate of the membrane filter element; the cycle water production is used to characterize the maximum water consumption that the soft water system can handle within a single regeneration cycle;

[0066] Calculation module 330 is used to calculate the contribution value of the target divalent ion based on the ion rejection rate, the first detection data, and the second detection data;

[0067] The update module 340 is used to determine the target adjustment coefficient based on the target divalent ion contribution value, and update the cycle water production based on the target adjustment coefficient.

[0068] In this embodiment, the water softening system of the water purifier includes at least a water softening module, a water metering module, and a control module. The water purification system includes a pre-filter 2, a power module, a pre-membrane ion concentration detection module (shown as detection module 1 in the figure), a membrane filter, a post-membrane ion concentration detection module (shown as detection module 2 in the figure), and a post-filter. One end of the pre-filter 2 is connected to one end of the power module, and the other end of the pre-filter 2 is connected to the pre-filter 1. One end of the pre-membrane ion concentration detection module 1 is connected to the power module, and the other end of the pre-membrane ion concentration detection module 1 is connected to the membrane filter. One end of the post-membrane ion concentration detection module 2 is connected to the membrane filter, and the other end of the post-membrane ion concentration detection module 2 is connected to the post-filter.

[0069] If the liquid water in the water purification system contains only divalent and monovalent ions, with divalent ions including calcium and magnesium ions and monovalent ions including sodium and potassium ions, the divalent ion rejection rate and monovalent ion rejection rate can be determined through testing based on the performance of the membrane filter cartridge. The calculation module 330 calculates the target divalent ion contribution value using the divalent ion rejection rate, monovalent ion rejection rate, first detection data, and second detection data. Based on the target divalent ion contribution value, the corresponding target adjustment coefficient is determined by looking up a table. The update module 340 performs mathematical operations on the target adjustment system and the periodic water production rate to obtain the updated periodic water production rate. This method calculates the divalent ion contribution value in the water by reverse calculation based on the purification effect of the water purification system, and then automatically and dynamically adjusts the periodic water production rate of the softening system based on the target adjustment coefficient to avoid wasting liquid water and salt, and to enhance the water softening effect.

[0070] Specifically, the calculation module 330 is used for:

[0071] The contribution value of divalent ions is calculated based on the first detection data, the second detection data, the divalent ion rejection rate, and the monovalent ion rejection rate.

[0072] For example, if the liquid water in the water purification system contains only monovalent and divalent ions, and the first detection data is T1 mg / L, the second detection data is T2 mg / L, and the divalent ion rejection rate of the water purifier is 'a', the monovalent ion rejection rate is 'b', and a > b, then the divalent ion pass-through rate through the membrane filter is 1 - a, and the monovalent ion pass-through rate is 1 - b. The formula for calculating the target divalent ion contribution value is Tax = (T2 - T1 + T1 * b) / (ba). If T2 is 100 (mg / L), T1 is 350 (mg / L), a is 90%, and b is 60%, then Tax = 133.3 mg / L.

[0073] In one embodiment, Figure 4 As shown, update module 340 includes:

[0074] Construction unit 341 is used to pre-construct the correspondence between the contribution values ​​of divalent ions and the adjustment coefficients in different ranges;

[0075] The screening unit 342 is used to screen out the target adjustment coefficient corresponding to the contribution value of the target divalent ion from the correspondence.

[0076] In this embodiment, the construction unit 341 pre-constructs a correspondence between adjustment coefficients kx1, kx2, kx3, and kx4 when Tax is in several different ranges such as [0.100], [100.200], [200.300], and [300.400], based on experimental data. The screening unit 342 then filters out the target adjustment system corresponding to the range of the target divalent ion contribution value from this correspondence. In this method, the setting range of the divalent ion contribution value can be adjusted according to the product requirements of the water purifier, with a range of 50 mg / L as the basis for gear adjustment.

[0077] In one embodiment, Figure 4 As shown, update module 340 includes:

[0078] Unit 343 is used to determine the preset divalent ion contribution reference value;

[0079] The calculation unit 344 is used to calculate the target adjustment coefficient based on the divalent ion contribution reference value and the target divalent ion contribution value.

[0080] In this embodiment, the determining unit 343 presets a divalent ion contribution reference value T0, and uses the ratio of the divalent ion contribution reference value T0 to the target divalent ion contribution value Tax as the target adjustment coefficient kx. T0 is set to 200 mg / L. When Tax is 200 mg / L, the target adjustment coefficient kx equals 1; when Tax is greater than 200 mg / L, the target adjustment coefficient kx is less than 1; and when Tax is less than 200 mg / L, the target adjustment coefficient kx is greater than 1. It should be noted that the product of the ratio of the divalent ion contribution reference value T0 to the target divalent ion contribution value Tax and a set proportionality coefficient can also be used as the target adjustment coefficient kx to improve the flexibility of the target adjustment coefficient calculation method.

[0081] This embodiment provides a system for calculating the periodic water production of a water purifier and softener, integrating water softening and purification functions into one. The calculation module calculates the contribution value of divalent ions in the water based on the purification effect of the water purification system. The update module then calculates the target adjustment coefficient based on the contribution value of divalent ions, automatically and intelligently adjusting the periodic water production of the softening system to avoid waste of liquid water and salt and improve the softening effect.
