[0041] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0042] Example 1

[0043] The calculation method of the periodic water production of the water purifier and softener of this embodiment comprises a water softening system and a water purification system, wherein the water purification system comprises a pre-membrane ion concentration detection module, a membrane filter element and a post-membrane ion concentration detection module, wherein 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, such as Figure 1 As shown, the calculation method includes:

[0044] S11, using 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, and obtain corresponding first detection data and second detection data;

[0045] S12, obtaining the cycle water production and the ion retention 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;

[0046] S13, calculating the target divalent ion contribution value according to the ion retention rate, the first detection data and the second detection data;

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

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

[0049] For the above steps S11-S14, if the liquid water in the water purification system includes only 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 divalent ion retention rate and the monovalent ion retention rate can be determined by testing according to the performance of the membrane filter element, and the target divalent ion contribution value is calculated by the divalent ion retention rate, the monovalent ion retention rate, the first detection data and the second detection data. According to the target divalent ion contribution value, the corresponding target adjustment coefficient is determined by looking up the table, and the target adjustment system is mathematically operated with the periodic water production to obtain the updated periodic water production. This method reversely calculates the divalent ion contribution value in the water through the purification effect of the water purification system, and then automatically and dynamically intelligently adjusts the periodic water production of the softening system based on the target adjustment coefficient to avoid wasting liquid water and salt and enhance the softening effect of water quality.

[0050] Wherein, step S13 specifically includes:

[0051] The divalent ion contribution value is calculated according to the first detection data, the second detection data, the divalent ion retention rate and the monovalent ion retention rate.

[0052] For example, if the liquid water in the water purification system only includes monovalent ions and divalent ions, the first test data is T1mg / L, the second test data is T2mg / L, the divalent ion retention rate of the water purifier is a, the monovalent ion retention rate is b, and a>b, then the divalent ion passing rate through the membrane filter is 1-a, and the monovalent ion passing rate is 1-b, then the calculation formula for 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=133.3mg / L.

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

[0054] S141, pre-constructing the corresponding relationship between the divalent ion contribution value and the adjustment coefficient in different ranges;

[0055] S142. Filter out a target adjustment coefficient corresponding to the target divalent ion contribution value from the corresponding relationship.

[0056] In this embodiment, the corresponding relationship between the 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] is constructed in advance based on experimental data, and the target adjustment system corresponding to the range of the target divalent ion contribution value is screened out from the corresponding relationship. The setting range of the divalent ion contribution value in this calculation method can be adjusted according to the product requirements of the water purifier and softener, and the gear adjustment is based on the span range of 50 mg / L.

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

[0058] S143, determining a preset divalent ion contribution reference value;

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

[0060] In this embodiment, the preset divalent ion contribution reference value is T0, and the ratio of the divalent ion contribution reference value T0 to the target divalent ion contribution value Tax is used as the target adjustment coefficient kx. Set T0=200mg / L, when Tax is 200mg / L, the target adjustment coefficient kx is equal to 1; when Tax is greater than 200mg / L, the target adjustment coefficient kx is less than 1; when Tax is less than 200mg / 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 the set proportional coefficient can also be used as the target adjustment coefficient kx to improve the flexibility of the target adjustment coefficient calculation method.

[0061] The present embodiment provides a method for calculating the periodic water production of a water purifier and softener. The calculation method integrates the softening and purification functions, reversely calculates the contribution value of divalent ions in the water through the purification effect of the water purification system, and then calculates the target adjustment coefficient based on the contribution value of the divalent ions, automatically and intelligently adjusts the periodic water production of the softening system, avoids the waste of liquid water and salt, and improves the softening effect.

[0062] Example 2

[0063] The calculation system of the periodic water production of the water purifier and softener of this embodiment includes a water softening system and a water purification 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. Figure 3 As shown, the computing system includes:

[0064] A 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 to obtain corresponding first detection data and second detection data;

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

[0066] A calculation module 330, configured to calculate a target divalent ion contribution value according to the ion retention rate, the first detection data, and the second detection data;

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

[0068] In this embodiment, the soft water system of the water purifier and softener includes at least a soft water module, a water metering module and a control module. The water purification system includes a pre-filter element 2, a power module, a pre-membrane ion concentration detection module (shown in the figure as detection module 1), a membrane filter element, a post-membrane ion concentration detection module (shown in the figure as detection module 2) and a post-filter element.

[0069] 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, the divalent ion retention rate and the monovalent ion retention rate can be determined by testing according to the performance of the membrane filter element, and the calculation module 330 calculates the target divalent ion contribution value from the divalent ion retention rate, the monovalent ion retention rate, the first detection data, and the second detection data, and determines the corresponding target adjustment coefficient by looking up the table according to the target divalent ion contribution value, and the update module 340 performs mathematical operations on the target adjustment system and the periodic water production to obtain the updated periodic water production. This method reversely calculates the divalent ion contribution value in the water through the purification effect of the water purification system, and then automatically and dynamically intelligently adjusts the periodic water production of the softening system based on the target adjustment coefficient to avoid wasting liquid water and salt and enhance the softening effect of water quality.

[0070] The calculation module 330 is specifically used for:

[0071] The divalent ion contribution value is calculated according to the first detection data, the second detection data, the divalent ion retention rate and the monovalent ion retention rate.

[0072] For example, if the liquid water in the water purification system only includes monovalent ions and divalent ions, the first test data is T1mg / L, the second test data is T2mg / L, the divalent ion retention rate of the water purifier is a, the monovalent ion retention rate is b, and a>b, then the divalent ion passing rate through the membrane filter is 1-a, and the monovalent ion passing rate is 1-b, then the calculation formula for 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=133.3mg / L.

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

[0074] A construction unit 341 is used to pre-construct the corresponding relationship between the divalent ion contribution value and the adjustment coefficient in different ranges;

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

[0076] In this embodiment, the construction unit 341 constructs the corresponding relationship between the 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] in advance according to the experimental data, and the screening unit 342 screens out the target adjustment system corresponding to the range of the target divalent ion contribution value from the corresponding relationship. In this method, the setting range of the divalent ion contribution value can be adjusted according to the product requirements of the water purifier and softener, and the gear adjustment is based on the span range of 50 mg / L.

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

[0078] A determination unit 343 is used to determine a 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 determination unit 343 presets the 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. Set T0=200mg / L, when Tax is 200mg / L, the target adjustment coefficient kx is equal to 1; when Tax is greater than 200mg / L, the target adjustment coefficient kx is less than 1; when Tax is less than 200mg / 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 the set proportional coefficient can also be used as the target adjustment coefficient kx to improve the flexibility of the target adjustment coefficient calculation method.
