Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent household appliances, and particularly to a water purifier and a method, system, device, and medium for determining the consumption of the filter element life thereof. Background Art

[0002] For water purification products, such as water purifiers, the core component is the filter element. The filter element is a consumable, and its life will expire after being used for a period of time. It is necessary to replace it in time to ensure that the water purifier can continue to provide effective water purification ability for users. Currently, there are three ways to judge the expiration of the filter element life of the water purifier. The first is to calculate according to time, and the life expires when the actual use time reaches 12 months. The second is to calculate according to the flow rate, and the life expires when the actual use flow rate reaches 5000L. The third way combines the first and the second, comprehensively considering time and flow rate, and as long as one of the actual use time and the actual use flow rate reaches the set value, the life is considered to expire.

[0003] According to these calculation methods, in areas with very good water quality, when the life expires, the filter element of the water purifier is still normal; in areas with very poor water quality, even if the actual use time and the actual use flow rate are both small and far from reaching the set value, the water quality of the effluent will deteriorate, and the water purifier needs to replace the filter element. None of these three methods can adjust the life adaptively according to the actual water quality situation, and there are problems such as inaccurate judgment of the life consumption of the filter element, resulting in unreasonable and inaccurate filter element replacement time, and ultimately leading to waste of filter elements and threats to the water use safety of users. Summary of the Invention

[0067] The present disclosure will be further described below by way of embodiments, but the present disclosure is not limited to the scope of the described embodiments.

[0068] Embodiment 1

[0069] This embodiment provides a method for determining the consumption of the filter element life in a water purifier. As Figure 1 shown, the determination method includes:

[0070] S101. Obtain the actual parameter values of the preset water quality parameters of the water before filtration during each process of filtering water by using the filter element at different working stages of the water purifier within a set time period.

[0071] Among them, the preset water quality parameters are used to characterize the water quality of the water in the water purifier. The preset water quality parameters include at least one of the indicators such as TDS (total dissolved solids), hardness, turbidity, and COD (chemical oxygen demand). The actual parameter values can be the actual values of the indicators such as TDS, hardness, turbidity, or COD, or the actual parameter values can also be determined according to multiple indicators of the preset water quality parameters. For example, the weighted average value of the actual parameter values of multiple indicators is used as the actual parameter value, and the specific setting method can be adjusted according to actual needs. Determining the actual parameter values through various types of indicators ensures the accuracy and reliability of the actual parameter values.

[0072] S102. Determine the actual influence coefficient corresponding to each actual parameter value on the filter element life.

[0073] S103. Based on the actual influence coefficients at each working stage, determine the target life consumption of the filter element within the set time period.

[0074] Specifically, the working stages of the water purifier include the normal water intake stage, the flushing stage of the filter element after water intake, and the static stage, and may also include a timed flushing stage at regular intervals. The purpose of flushing the filter element is mainly to reduce the influence of the concentrated water in front of the membrane on the filter element life and can effectively improve the filter element life.

[0075] The filter elements of the water purifier include a pre-filter element (or a pre-composite filter element), a membrane filter element, and a post-filter element (or a post-composite filter element), and the target life consumption of each filter element can be determined separately.

[0076] In this embodiment, by obtaining the actual parameter values of the preset water quality parameters of the water before filtration during the process of filtering water with the filter element in different working stages of the water purifier within a set time period, the actual influence coefficient on the filter element life is determined accordingly, and then the target life consumption of the filter element within the set time period is obtained, which ensures the accuracy of the judgment of the filter element life consumption in the water purifier, the rationality and accuracy of the filter element replacement time, reduces the waste of filter elements, guarantees the user's water use safety, and improves the product performance of the water purifier.

[0077] Embodiment 2

[0078] This embodiment provides a method for determining the life consumption of the filter element in a water purifier, which is a further improvement on Embodiment 1.

[0079] In an implementable solution, as Figure 2 shown, step S102 includes:

[0080] S1021. Determine the actual influence coefficient corresponding to the actual parameter value according to the actual parameter value and the pre-constructed mapping relationship;

[0081] Among them, the mapping relationship is the mapping relationship between the water quality parameter value range and the preset influence coefficient on the filter element life in each working stage of the water purifier.

[0082] Specifically, taking TDS as an example of the preset water quality parameter, according to the experimental test data, different water quality parameter value ranges of TDS and the corresponding preset influence coefficients on the filter element life are obtained, and a mapping relationship table between the water quality parameter value range and the preset influence coefficient is constructed. The obtained actual parameter value of TDS is compared with the water quality parameter value range of TDS to determine the water quality parameter value range to which the actual parameter value belongs, and the preset influence coefficient corresponding to this water quality parameter value range is the actual influence coefficient corresponding to the actual parameter value.

[0083] The filter elements are divided into pre-filter elements, membrane filter elements, and post-filter elements. Different filter elements correspond to different preset influence coefficients and also different actual influence coefficients.

[0084] When the working stage is the water intake stage or the static stage, the actual influence coefficients corresponding to the pre-filter, the membrane filter, and the post-filter are all positive; when the working stage is the flushing stage, the actual influence coefficient corresponding to the pre-filter is positive, the actual influence coefficient corresponding to the membrane filter is negative, and the actual influence coefficient corresponding to the post-filter is zero. The situation of the preset influence coefficient being positive, negative, or zero is the same as that of the actual influence coefficient.

[0085] The corresponding relationship between the water quality parameter value range of TDS (referred to as the TDS range in the table) and the preset influence coefficient in the water intake stage is shown in the following table.

[0086] TDS range Pre-filter Membrane filter Post-filter 0～100 K11 K21 K31 100～200 K12 K22 K32 200～300 K13 K23 K33 300～400 K14 K24 K34 Above 400 K15 K25 K35

[0087] For example, when the actual parameter value of TDS of tap water is 150, the actual influence coefficient Kx of the pre-filter is K12.

[0088] The corresponding relationship between the water quality parameter value range of TDS and the preset influence coefficient in the flushing stage is shown in the following table.

[0089] TDS range Pre-filter Membrane filter Post-filter 0～100 P11 P21 P31 100～200 P12 P22 P32 200～300 P13 P23 P33 300～400 P14 P24 P34 Above 400 P15 P25 P35

[0090] For example, when the actual parameter value of TDS of tap water is 150, the actual influence coefficient Px of the pre-filter is P12.

[0091] Among them, P11~P1N are positive numbers, indicating that flushing consumes the life of the pre-filter, P21~P2N are negative numbers, indicating that flushing improves the life of the membrane filter. Flushing generally does not pass through the post-filter, so it does not affect the life of the post-filter. Therefore, P31~P3N are 0.

[0092] The corresponding relationship between the water quality parameter value range of TDS and the preset influence coefficient in the static stage is shown in the following table.

[0093] TDS range Pre-filter Membrane filter Post-filter 0～100 S11 S21 S31 100～200 S12 S22 S32 200～300 S13 S23 S33 300～400 S14 S24 S34 Above 400 S15 S25 S35

[0094] For example, when the actual parameter value of TDS of tap water is 150, the actual influence coefficient Sx of the pre-filter is S12.

[0095] In this solution, by the actual parameter value and the pre-constructed mapping relationship between the water quality parameter value range and the preset influence coefficient, the actual influence coefficient corresponding to the actual parameter value is determined, ensuring the accuracy and reliability of the actual influence coefficient.

[0096] In addition, an arithmetic formula between the preset influence coefficient and the water quality parameter value of the preset water quality parameter can be pre-constructed, and the actual influence coefficient can be obtained according to this arithmetic formula in which the preset influence coefficient and the water quality parameter value of the preset water quality parameter are in a certain relationship.

[0097] Taking the water intake stage and the preset water quality parameter TDS as an example, the water quality parameter value of TDS obtained from the actual test is Tx, the preset influence coefficient is Kx, and the relationship formula between the preset influence coefficient and the water quality parameter value of the preset water quality parameter is Kx = ax + bx * Tx, where ax and bx are empirical values obtained from experimental tests, and different values can be used for different filter elements, as shown in the following table.

[0098] Constant Pre-filter Membrane filter Post-filter ax a11 a12 a13 bx b11 b12 b13

[0099] When the working stage is the flushing stage or the standing stage, the setting methods of the preset water quality parameters such as hardness, turbidity, or COD are similar to the setting method here, and will not be elaborated here.

[0100] In an implementable solution, step S103 includes:

[0101] S1031. Based on the stage influence parameters and the actual influence coefficients in each working stage, obtain the stage life consumption corresponding to each working stage.

[0102] Among them, when the working stage is the water intake stage, the stage influence parameter is the water intake volume;

[0103] When the working stage is the flushing stage, the stage influence parameter is the flushing water volume;

[0104] When the working stage is the standing stage, the stage influence parameter is the standing duration.

[0105] S1032. Take the sum of the stage life consumptions corresponding to each working stage as the target life consumption.

[0106] Specifically, obtain the stage influence parameters and the actual influence coefficients in each working stage, and calculate the stage life consumption Ax corresponding to the water intake stage, the stage life consumption Bx corresponding to the flushing stage, and the stage life consumption Cx corresponding to the standing stage respectively. The target life consumption Gx = Ax + Bx + Cx. In the specific implementation process, the preset life amount of the filter element can be set to 100%, and the life of the filter element is consumed in percentage in different working stages.

[0107] In this solution, taking the sum of the stage life consumptions corresponding to different working stages as the target life consumption fully considers the influence of different working stages of the water purifier on the filter element life, and ensures the accuracy and reliability of the calculation of the target life consumption.

[0108] In an implementable solution, as Figure 3 shown, step S1031 includes:

[0109] S10311. Based on the corresponding stage influence parameters and actual influence coefficients during the process of filtering water with a filter element each time under each working stage, obtain the first life consumption corresponding to each time of filtering water with the filter element.

[0110] S10312. Take the sum of each first life consumption under each working stage as the stage life consumption corresponding to each working stage.

[0111] Specifically, the stage life consumption Ax corresponding to the water intake stage = A1 + A2 + A3 + …… + AN, where N is a positive integer. AN represents the life consumption of the filter element for the Nth water intake. AN = Kx * dN, dN is the water intake volume for the Nth water intake. The actual influence coefficient Kx is the actual influence coefficient corresponding to the real-time measured water quality situation during the Nth water intake. Kx can be regarded as the consumption percentage of the filter element life per unit water intake volume. The water quality situation is represented by the actual parameter value of the preset water quality parameter, such as the TDS value.

[0112] The stage life consumption Bx corresponding to the flushing stage = B1 + B2 + B3 + …… + BM, where M is a positive integer. BM represents the life consumption of the filter element for the Mth flushing. BM = Px * dM, dM is the flushing water volume for the Mth flushing. The actual influence coefficient Px is the actual influence coefficient corresponding to the real-time measured actual parameter value of the preset water quality parameter during the Mth flushing. Px can be regarded as the consumption percentage of the filter element life per unit flushing water volume.

[0113] The stage life consumption Cx corresponding to the static stage = C1 + C2 + C3 + …… + CT, where T is a positive integer. CT represents the life consumption of the filter element for the Tth static state. CT = Sx * dT, dT is the static duration for the Tth static state. The actual influence coefficient Sx is the actual influence coefficient corresponding to the real-time measured actual parameter value of the preset water quality parameter during the Tth static state. Sx can be regarded as the consumption percentage of the filter element life per unit static duration.

[0114] In this solution, based on the corresponding stage influence parameters and actual influence coefficients during the process of filtering water with a filter element each time under each working stage, obtain the first life consumption corresponding to each time of filtering water with the filter element, and take the sum of each first life consumption under each working stage as the stage life consumption corresponding to each working stage, considering the influence of the stage influence parameters and actual influence coefficients on the filter element life consumption when filtering water with the filter element multiple times under each working stage, ensuring the accuracy and reliability of the stage life consumption.

[0115] In an implementable solution, the set time period includes the time period from the activation time of the filter element to the current moment.

[0116] After step S103, it further includes:

[0117] S104, obtaining the difference between the target life consumption and the preset life of the filter element;

[0118] S105, when the difference meets the first preset condition, a filter element replacement reminder is issued;

[0119] S106, when the difference meets the second preset condition, a reminder of the expiration of the filter element life is issued.

[0120] Specifically, the filter life consumption can be monitored in real time, multiple times at a set time interval, or only a set number of times within a set period. After step S104, steps S105 and S106 can be performed in sequence, or only step S105 or step S106 can be performed, which can be set or adjusted according to the monitoring frequency of the filter life consumption and actual needs.

[0121] After determining the target life consumption of the filter element, the target life consumption Gx of the filter element can be compared with the preset life consumption G0 of the filter element. The comparison method includes but is not limited to calculating the ratio and calculating the difference. Taking calculating the difference as an example, the difference ΔG=G0-Gx is calculated.

[0122] When the difference meets the first preset condition, a filter element replacement reminder is issued, and the first preset condition may be that the difference ΔG is less than or equal to 20% of G0. When the difference meets the second preset condition, a filter element life expiration reminder is issued, and the second preset condition may be that ΔG is less than or equal to 0.

[0123] The filter replacement reminder reminds the user that the filter life is about to expire, giving the user an advance warning to avoid being too late to replace the filter when the filter life expires. The filter life expiration reminder reminds the user that the filter life has expired and needs to be replaced in time.

[0124] A multi-level reminder method can also be used to remind the user that half of the filter life is consumed when the difference ΔG is less than or equal to 50%, remind the user that 80% of the filter life is consumed when the difference ΔG is less than or equal to 20%, and remind the user that the filter life is consumed when the difference ΔG is less than or equal to 0. The reminder method can be voice broadcast, linkage with user devices such as mobile phones to send text message reminders, mobile phone application message reminders, etc. The above 0, 20%, 50%, 80% are just examples and can be set or adjusted according to actual needs.

[0125] In this solution, the difference between the target life consumption and the preset life of the filter element is obtained, and whether the life of the filter element has expired is judged based on the difference. When the target life consumption is greater than or equal to the preset life, it is determined that the life of the filter element has expired, and the user is promptly reminded to replace the filter element, thereby ensuring accurate judgment of the life usage of the filter element and ensuring the user's water safety.

[0126] The working principle of the method for determining the filter element life consumption in the water purifier of this embodiment will be described below with specific examples:

[0127] As Figure 3 shown, start to determine the filter element life consumption in the water purifier. Preset the preset life amount G0 of the water purifier filter element. According to the actual parameter values of the preset water quality parameters of the water before filtration during each filtration of water by the filter element in different working stages of the water purifier within the set time period, determine the actual influence coefficient Kx in the water intake stage, the actual influence coefficient Px in the flushing stage, and the actual influence coefficient Sx in the static stage. Calculate the stage life consumption amounts Ax, Bx, and Cx corresponding to different working stages, and calculate the target life consumption amount Gx of the filter element. Compare Gx with G0 to determine whether the life of the filter element has expired.

[0128] In this embodiment, by obtaining the actual parameter values of the preset water quality parameters of the water before filtration during each filtration of water by the filter element in different working stages of the water purifier within the set time period, the actual influence coefficient affecting the filter element life is determined accordingly, and then the target life consumption amount of the filter element within the set time period is obtained, ensuring the accuracy of the judgment of the filter element life consumption in the water purifier, the rationality and accuracy of the filter element replacement time, reducing filter element waste, ensuring the user's water use safety, and improving the product performance of the water purifier.

[0134] It should be noted that for the system for determining the filter element life consumption in the water purifier of this embodiment, it is based on the corresponding Method Embodiment 1, so the relevant parts can refer to the partial description of Method Embodiment 1.

[0135] In this embodiment, by obtaining the actual parameter values of the preset water quality parameters of the water before filtration during the process of filtering water with the filter element in different working stages within a set time period, the actual influence coefficient on the filter element life is determined accordingly, and then the target life consumption of the filter element within the set time period is obtained, ensuring the accuracy of the judgment of the filter element life consumption in the water purifier, the rationality and accuracy of the filter element replacement time, reducing the waste of filter elements, ensuring the user's water use safety, and improving the product performance of the water purifier.

[0136] Embodiment 4

[0138] In an implementable solution, the influence coefficient determination module 2 is further configured to determine the actual influence coefficient corresponding to the actual parameter value according to the actual parameter value and the pre-constructed mapping relationship;

[0139] wherein, the mapping relationship is the mapping relationship between the water quality parameter value range and the preset influence coefficient on the filter element life in each working stage of the water purifier.
