The present application provides an embodiment of a method for detecting the lifetime of a filter element of a water purifier, and it should be noted that, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different sequence than that shown here.
The method for detecting the service life of the filter element of the water purifier comprises the following steps:
step S10, determining a first time length required by the attenuation of a filter element of the water purifier at a first preset time by a preset value;
it should be noted that, in the conventional filter element life algorithm, the amount of water that can be filtered by the filter element L1 is directly calculated according to factors such as a service area TDS value (variable), a laboratory TDS value, a service area life, a laboratory life, a water quality coefficient, an intelligent flushing coefficient, and the like, the number of life days T1 is calculated according to the estimated daily water consumption (constant), and whether the filter element life is due is determined according to whether the water consumption exceeds L1 or whether the number of life days exceeds T1. In the life decay mode, first, the filter life display is displayed in percentage and decay is performed; and secondly, when the water consumption Y is L1/100 or the power-on time of the water purifier is T1/100, the service life is reduced by 1%, and the next calculation interval is automatically entered. Updating the TDS value (dynamic average value, which is not updated after reaching 32 times) every hour in each life interval, and calculating the life and the service time of the current interval; the attenuation mode of the filter element is interval attenuation. Through the technical description, the water quantity which can be filtered by the filter element is calculated only by considering the water quality, the use strength (daily net water quantity) of the filter element is not considered, and the use strength is considered in the subsequent service life calculation days, but the use strength is fixed, so that the real use strength of a user cannot be reflected. The service life of the filter element is dynamically calculated according to the use strength and the water quality information of different users, and the service life of the filter element is truly reflected.
In the embodiment, the water purifier calculates a first time length required by the filter element to decay by a preset value in a first preset time according to the use condition, wherein the first preset time is the next 24 hours of the decay time point of the filter element, and if the life of the filter element decays from 90% to 89% at the 24 point of No. 1, No. 2 is taken as the first preset time; the preset value is 1%, and may be other values, which are not limited herein; the first duration is the number of days of decay corresponding to 1% decay in the life of the filter element.
The water purifier acquires the washing coefficient of the pre-storage filter element, the preset water purification amount, the daily water purification amount and the water quality information of the water to be purified, wherein:
the flushing coefficient of the filter element can be revised according to different filter element film rolling modes/electric control flushing procedures;
the preset purified water amount refers to the standard laboratory filtered water amount;
the daily clean water amount refers to the use strength of the filter element, namely the water purified each day, and is determined by the following method: calculating data once every 0 point, calculating data for the second time every 24 points, and taking the difference value of the two data as daily net water quantity, namely the actual total net water quantity (L) of the equipment in the past 24 hours;
the water quality information of the water to be purified comprises a water quality coefficient and a total dissolved solids value (TDS value), and the total dissolved solids value comprises an actual inlet water TDS value (inlet water total dissolved solids value) and a standard laboratory TDS value (preset total dissolved solids value), wherein the water quality coefficient is preset; total Dissolved Solids (TDS) means how many milligrams of dissolved solids are dissolved in 1 liter of water, and the TDS value is higher, and it is more to indicate the solute that contains in the water, and the net water section and the play water section of filter core are equipped with TDS monitoring sensor respectively for detect into water TDS value and play water TDS value.
Further, the water purifier calculates the attenuation time required by the preset attenuation value (such as 1%) of the filter element according to the flushing coefficient, the standard laboratory filtered water quantity, the daily purified water quantity, the water quality coefficient, the actual intake water TDS value and the standard laboratory TDS value. In one embodiment, a first difference between the incoming water TDS value and the standard laboratory TDS value is calculated, a first product between the first difference, the water quality coefficient, and the flush coefficient is calculated, a second difference between the first coefficient and the first product is calculated, a second product between the second difference and the laboratory standard filtered water volume is calculated, a quotient between the second product, the daily water volume, and the second coefficient is calculated, and finally, the quotient is used as the duration required by the preset filter element decay value. Referring to equation (1), the number of decay days corresponding to 1% decay in filter element life can be calculated based on equation (1):
T0＝(1-(W1-W0)*X*C)*L0/Y/100 (1)
in the formula (1), T0 indicates the number of decay days (i.e., decay time length) corresponding to 1% of the lifetime calculated from the past 24-hour use;
w1 refers to the actual influent TDS value;
w0 refers to standard laboratory TDS values;
x is water quality coefficient;
c is the washing coefficient (revised according to different filter element rolling membrane modes/electric control washing programs);
l0 refers to the laboratory standard filtered water volume (preset purified water volume);
y is daily net water amount, namely actual use intensity, and is defined according to the water amount change in 24 hours;
1 refers to the first coefficient;
100 refers to the second coefficient.
When the TDS value is abnormally high and the water consumption is small, the attenuation days corresponding to 1% calculated based on the formula (1) are abnormal, namely, the difference between the attenuation days corresponding to 1% is large, at this time, the water purifier automatically adopts pre-stored data to adjust the TDS value and the daily purified water quantity, for example, when the actual TDS is greater than 350, 350 is taken for calculation, and when the actual TDS is less than 50, 50 is taken for calculation. And when the actual use intensity is larger than 16L/day, 16L is taken for calculation, and when the actual use intensity is smaller than 8L, 8L/day is taken for calculation, wherein the pre-stored TDS data and daily purified water quantity data are determined according to historical data.
Step S20, determining a second time length required by the filter element to attenuate the preset value in each second preset time in the first time length;
in this embodiment, after the water purifier determines T0 based on formula (1), it continues to determine the second time period required by the filter element to decay by the preset value at each second preset time according to formula (1), i.e., the decay time period required by the filter element to decay by 1% at each second preset time is calculated according to the actual intake water TDS value, the standard laboratory TDS value, the water quality coefficient, the flushing coefficient, the laboratory standard filtration water volume, and the daily clean water volume. The second preset time is 24 hours after the first preset time, and if the first preset time is No. 6, the second preset time is every day after No. 6.
Step S30, determining the decay time point of the filter element according to the first time length and the second time length;
in this embodiment, the water purifier obtains each target second preset time, where the second duration determined based on the second preset time is less than or equal to the first duration, determines the actual total operation duration of the water purifier at the first preset time and each target second preset time, and then determines the decay time point according to the target second preset time corresponding to the actual total operation duration reaching the first time duration. For example, referring to table 1, table 1 shows T0 corresponding to the first preset time and each second preset.
TABLE 1
| Date | Number 1 | Number 2 | No. 3 | Number 4 | Number 5 | Number 6 |
| T0 (Unit/day) | T0＝3 | T0＝2 | T0＝3 | T0＝3 | T0＝4 | T0＝2 |
In table 1, assuming that the first preset time is 1, the second preset time is 2 to 6, and as can be seen from table 1, in the second preset time, T0 of nos. 2, 3, 4 and 6 is not more than 3, that is, T0 of three days of nos. 1 to 3 is not more than 3, and at this time, 24 o' clock of No. 3 is taken as the decay time point of the filter element. Assuming that T0 ≦ 4 of No. 3 does not satisfy T0 ≦ 3, and T0 ≦ 3 of No. 4, and T0 ≦ 3, that is, T0 ≦ 3 of three days of nos. 1, 2, and 4, point No. 4 24 is taken as the decay time point of the filter element. For example, referring to table 1, assuming that the decay time point is 24 points of No. 4, the decay number of days corresponding to 1% of the life of the filter element is recalculated at No. 5, and the subsequently calculated T0 is compared with the T0 calculated at No. 5 as a reference, assuming that the number of naturally used days after No. 5 and No. 5 is greater than T0, the life percentage decays by 1%, and so on, the next decay number of days corresponding to 1% is calculated.
And step S40, when the attenuation time point is reached, updating the residual service life of the filter element according to the preset value.
In this embodiment, when the decay time point of the filter element is reached, the water purifier automatically calculates a third difference between the preset value and the remaining life, and then uses the third difference as the updated remaining life of the filter element. For example, assuming that the remaining life of the water purifier is 88% and the preset value is 1%, the remaining life of the filter element is 88% -1% ═ 87% when the decay time point of the filter element is reached.
The life decay rule judges whether the natural using days exceed the interval T0, and the life percentage will decay by 1% when the natural using days exceed 1T 0. Thus, it is also possible to obtain the decay times of the filter insert when the decay time point of the filter insert is reached and then to determine the remaining life of the filter insert on the basis of the decay times. In one embodiment, the attenuation times of the filter element attenuation preset value are obtained, the remaining life percentage of the filter element is determined according to the attenuation times, the remaining life days of the filter element are determined according to the life percentage and the preset life days, and finally the remaining life percentage and/or the remaining life days are/is used as the updated remaining life. For example, the decay is n, the percentage of life decays n%, and the number of life days is dynamically updated according to the new percentage, wherein the formula of the percentage of life and the number of life days is as follows:
percentage of remaining life ═ 1-1% × (2)
Remaining Life days ═ standard life days × remaining life percentage (3)
In the formula (2), N is the nth interval decay.
Based on the above formula, the remaining life percentage and the number of days of remaining life of the filter element can be calculated, and for example, assuming that the number of times of attenuation of the filter element is 30 times and the number of days of standard life is 100 days, the corresponding remaining life percentage (1-1% × 30) is 70%, and the number of days of remaining life is 100 × 70% is 70 days.
After the filter element is used for a long time, the water purifying capacity of the filter element is invalid due to the blockage of intercepted objects, the multiplication of intercepted microorganisms and the like, namely the service life of the filter element is due, and therefore, the filter element needs to be replaced in time for ensuring the drinking water safety. In one embodiment, when the remaining life of the filter element reaches a predetermined life range (e.g., 0% to 2%), the water purifier outputs a filter element replacement prompt to prompt the user to replace the filter element.
Because the service life information of the filter element of the cloud and the water purifier is synchronously updated, after the residual service life of the filter element is updated, the updated residual service life of the water purifier is sent to the cloud, and the cloud updates the pre-stored residual service life according to the updated residual service life. Wherein, the high in the clouds also can calculate the surplus life according to the in service behavior of filter core, and that is, high in the clouds and water purifier all can realize the calculation of filter core life-span.
According to the embodiment, the residual service life of the filter element is calculated by combining the water quality dynamic for 24 hours according to the use strengths (daily purified water amount) of different users, so that the real-time calculation of the service life of the filter element is realized, and meanwhile, the accuracy of the calculation of the service life of the filter element is improved.
Further, referring to fig. 3, a second embodiment of the method for detecting the lifetime of the filter element of the water purifier is provided.
The second embodiment of the method for detecting the lifetime of a filter element of a water purifier differs from the first embodiment in that, between the step of determining a second time period required for the filter element to decay by the preset value in each second preset time and the step of determining the decay time point of the filter element according to the first time period and the second time period, the method further comprises:
step S21, when the second time length is shorter than a preset time length, obtaining the shortest second time length required for attenuating the preset value within the second preset time length according to the preset total service life of the filter element;
and step S22, updating the second time length according to the shortest second time length.
In order to avoid the occurrence of the abnormal attenuation condition of the filter element and ensure the regularity of the attenuation curve, the lowest attenuation standard is determined, in one embodiment, when the second time length is less than the preset time length, the shortest second time length required by the attenuation preset value within the second preset time is obtained according to the preset total service life of the filter element, and then, the second time length is updated according to the shortest second time length. For example, assuming that 1% calculated based on the formula (1) corresponds to days of decay < (standard life days ÷ 100), the life calculation is disabled, at which time the water purifier is forcibly modified by the shortest life setting T0. Wherein the shortest life setting is related to the life span of the filter element (the preset total life span), for example, assuming that the life span of the filter element is 1 to 2 years, the shortest life span setting T0 is (standard number of life days-40)/100; assuming that the life span of the filter element is 2-4 years, the shortest life setting T0 is (standard days-75)/100; assuming a filter element life span of 4-5 years, the minimum life setting T0 is (standard days-90)/100. The present embodiment adopts a percentage lifetime decay mode, wherein the number of decay days corresponding to 1% of the lifetime is dynamically changed, and therefore the decay of the new lifetime is also dynamically changed, but the standard lifetime is the standard lifetime of the laboratory, that is, the lifetime calculated under the standard simulation environment. Referring to equation (4), based on equation (4), the number of standard decay days for 1% decay in filter element life can be calculated:
T1 ＝(1-(W2-W0)* X * C)* L0 / Y1 (4)
in the formula (4), T1 indicates the number of standard decay days corresponding to 1% of the lifetime calculated from the past 24-hour usage;
w2 refers to the TDS value of the inlet water under the standard test environment;
w0 refers to standard laboratory TDS values;
x is water quality coefficient;
c is the washing coefficient (revised according to different filter element rolling membrane modes/electric control washing programs);
l0 refers to the laboratory standard filtered water volume (preset purified water volume);
y1 refers to standard water amount of 10L/day.
In the embodiment, when the attenuation of the filter element is abnormal, T0 is forcibly modified through the shortest service life setting, so that the abnormal attenuation condition of the filter element is avoided, and the regularity of an attenuation curve is ensured.

Further, the local device judges whether the natural service days of the filter element are larger than T0, if the natural service days of the filter element are larger than T0, the remaining life percentage and the remaining life days of the filter element are calculated based on T0, and the calculated remaining life percentage and the calculated remaining life days are uploaded to the cloud, so that data of the cloud and the local device are synchronized. If the residual life percentage and the residual life days of the filter element are smaller than or equal to T0, the local end of the equipment also uploads the residual life percentage and the residual life days of the filter element to the cloud end, and at the moment, the cloud end does not update when the data are determined not to change.
