In one embodiment, as shown in fig. 1, a method for detecting a lifetime of a filter cartridge is provided, which is exemplified by the method applied to a controller, and may include the following steps:
step 202, acquiring the filtered water volume of the filter in a water filtering state each time within a preset time, a first TDS value of a water inlet end of the filter and a second TDS value of a water outlet end of the filter;
The preset time can be set according to actual conditions, for example, the preset time can be 24 hours; when the user uses the filter, can trigger the filter and filter water, the filter can be in the drainage state promptly, and the filter is the water filter volume that the water filter is in the drainage state promptly for the filterable water volume of filter under the drainage state; the end of intaking of filter can set up TDS detection sensor with the play water end, TDS detection sensor detects the TDS value of rivers and sends for the controller, the filter is in the first TDS value of filter end of intaking at every turn under the drainage state promptly for the TDS value of being about to by filtered water when filtering at every turn, and the filter is in the second TDS value of filter play water end at every turn promptly for the TDS value of being filtered water when filtering at every turn under the drainage state, the quality of water in different areas and different seasons is different, can influence the TDS value that gets into the water filter end of intaking, and then also can influence the TDS value that the water filter goes out the water end.
Step 204, obtaining the actual filtering capacity of the filter element of the filter according to each filtered water amount, each first TDS value and each second TDS value;
the actual filtering capacity of the filter element is the capacity of the current residual filter element consumable for actually filtering water.
Step 206, determining the residual life of the filter element based on the actual filtering capacity and the preset filtering capacity; the preset filtering capacity is determined according to the water using scene.
The preset filtering capacity is the expected allowable filtering capacity of the filter element, different water use scenes have different requirements on the expected allowable filtering capacity of the filter element, and when the actual filtering capacity of the filter element is lower than the preset filtering capacity, the actual filtering capacity of the filter element possibly cannot enable the filtered water quality to meet the requirements of the water use scenes. For example, when the water usage scene is drinking, because the requirement on the filtered water quality is very high, if the filtering capacity of the filter element does not meet the requirement, the user may have a certain influence on the body after drinking the filtered water, and therefore the preset filtering capacity can be set to 30% according to the water usage scene; if the water using scene is a scene of washing hands, bathing and the like, compared with the drinking scene, the water using scene is a scene, the requirement on the filtered water quality is lower, so that the preset filtering capacity of the filter element can be lower than that of the drinking scene, and the preset filtering capacity can be set to be 20% according to the water using scene; the preset filtering capacity can be specifically set according to the actual water usage scene.
Specifically, within the preset time, when the filter is in a water filtering state every time, the water filtering amount of the filter, a first TDS value of a water inlet end of the filter and a second TDS value of a water outlet end of the filter are acquired, so that the actual filtering capacity of the filter element of the filter can be obtained according to the acquired water filtering amounts, the acquired first TDS values and the acquired second TDS values, the residual life of the filter element is determined based on the actual filtering capacity and the preset filtering capacity determined according to the water usage scene, and the residual life of the filter element is the allowable filtering capacity expected for the filter element. When the remaining life of the filter element is about to be exhausted, the filter element cannot filter the water in the current water using scene with the preset filtering capacity.
This application is according to the water filtration volume that the filter is in under the drainage state at every turn in the time of predetermineeing, be in the first TDS value of filter water inlet end and the second TDS value of play water end under the drainage state at every turn, obtain the actual filtering capability of filter core, demand to the filter core filtering capability according to the scene of using water, and combine the actual water filtering capability that obtains to determine the remaining life of filter core, can help preventing because of the quality of water difference that external factors such as different regions or different seasons arouse, and the influence to the judgement of the remaining life of the actual filtering capability of filter core and filter core, thereby obtain more accurate filter core filtering capability. The setting of the preset time can also make the filter not need to detect the first TDS value of the water filtration quantity, the water inlet end of the filter and the second TDS value of the water outlet end in real time, the filter is not needed to be electrified and networked in real time, only the data in a period of time need to be acquired, the requirement on components is low, and the energy consumption of filter source devices is also reduced. And, this application is according to the demand of water scene to filter core filtering capacity to combine the actual water filtering capacity who obtains to determine the surplus life-span of filter core, further improved the rate of utilization of filter core and to the accuracy of filter core life-span detection.
In one embodiment, as shown in fig. 2, before the step 202 of obtaining the filtered water amount of the filter in the water filtering state each time within the preset time, the first TDS value of the water inlet end of the filter and the second TDS value of the water outlet end of the filter, the method may further include:
step 302, judging whether the water using time is more than a threshold value;
step 304, if yes, confirming that the filter is in a water filtering state;
and step 306, if not, confirming that the filter is not in a water filtering state.
The threshold may be set according to actual conditions, and for example, the threshold may be 1 minute.
In particular, in some cases, the user may accidentally touch the filter, for example if the filter is used for filtering in a water heater, the user may inadvertently turn on the water softening function, i.e. the filter filtering function, while using the water heater, but in the case of such accidental touching of the filter, the filter is soon turned off by the user, in which case the detection accuracy of the service life of the filter cartridge is low, so that the service life of the filter does not need to be detected in the case of such accidental touching. The filter is judged whether to be in the water filtering state or not by setting the threshold value and comparing the water using time, the filter is confirmed to be in the water filtering state when the water using time is less than or equal to the threshold value, and the filter is not confirmed to be in the water filtering state when the water using time is less than or equal to the threshold value, so that the condition that the filter is touched by mistake is eliminated, and the accuracy of the detection of the service life of the filter element of the filter is ensured.
In one embodiment, the step 202 of obtaining the filtered water amount of the filter in the water filtering state each time within the preset time, the first TDS value at the water inlet end of the filter, and the second TDS value at the water outlet end of the filter may include:
and periodically acquiring each filtered water quantity, each first TDS value and each second TDS value.
In particular, it is considered that the water quality may be changed in different seasons, and the change of the water quality may consume consumables of the filter cartridge, thereby affecting the filtering capability of the filter cartridge, and thus, the filtering capability of the filter cartridge needs to be re-checked periodically. This application has set for the filter to be in the filtration volume under the drainage state at every turn in the time of predetermineeing to the filter, the first TDS value of the end of intaking of filter and the second TDS value of play water end carry out the periodicity and acquire, it can be a week to acquire the cycle, promptly after the remaining life a week of confirming the filter core, acquire the filtration volume that the filter is in the drainage state at every turn in the time of predetermineeing again, the first TDS value of the end of intaking of filter and the second TDS value of play water end, and through each filtration volume, each first TDS value and each second TDS value, obtain the actual filtering quality of the filter core of filter, and based on actual filtering quality and the remaining life who predetermines the filtering quality and confirm the filter core, the remaining life of this filter core then is the remaining life of a week after definite, thereby this application can prevent the water quality change that seasonal change leads to, influence to filter core remaining life.
The application can flexibly and accurately adjust the actual filtering capacity of the filter according to the water quality change of different regions and different seasons, thereby reducing the influence of external factors on the judgment of the service life of the filter element of the filter.
In one embodiment, as shown in fig. 3, the step 204 of obtaining the actual filtering capacity of the filter element of the filter according to each filtered water amount, each first TDS value and each second TDS value may include:
step 402, obtaining a TDS difference value between the first TDS value and the second TDS value of the filter in the water filtering state each time according to the first TDS value and the second TDS value of the filter in the water filtering state each time, and obtaining a total filtered water amount of the filter in a preset time according to the filtered water amount of the filter in the water filtering state each time;
step 404, determining an average value of all TDS difference values based on all TDS difference values;
and step 406, obtaining the actual filtering capacity according to the average value and the total water filtering amount.
Specifically, under the condition of obtaining first TDS value, second TDS value and the water filtration volume that the filter is in water filtration state at every turn in preset time, can be worth obtaining the TDS difference value that the filter is in water filtration state first TDS value and second TDS value at every turn according to each first TDS value and each second TDS, promptly: Δ TDS ═ TDS 1-TDS2Wherein Δ TDS is a TDS difference between the first TDS value and the second TDS value, TDS1Is the first TDS value, TDS2A second TDS value; and then determining the average value of all the TDS difference values based on all the TDS difference values, namely:
wherein, Delta TDS1A TDS difference value between a first TDS value and a second TDS value of the water filter in a water filtering state for the first time within a preset time, delta TDS2A TDS difference value between a first TDS value and a second TDS value of the water filter in a water filtering state for the second time in a preset time, delta TDS3A TDS difference value between a first TDS value and a second TDS value of the water filter in a water filtering state for the second time in a preset time, delta TDSnThe TDS difference value between the first TDS value and the second TDS value of the water filter in the water filtering state for the nth time in the preset time, n is the time of the water filter in the water filtering state in the preset time,
the average value of all TDS difference values of the water filter in a preset time is obtained; and the total filtered water amount of the filter in the preset time can be the sum of the filtered water amounts of the filter in the water filtering state each time in the preset time, namely: l isGeneral assembly＝(L1+L2+…+Ln) Wherein L isGeneral assemblyFor the total filtered water amount in a predetermined time, L1For the first time within a predetermined time, the filtered water quantity, L, of the filter in the filtered water state 2The water filtration amount of the filter in the water filtration state for the second time within the preset time, LnThe water filtration amount of the filter in the water filtration state for the nth time within the preset timeN is the frequency of the water filter in a water filtering state within a preset time; finally, the average value and the total filtered water volume of the filter in a water filtering state within a preset time are processed by adopting a correction coefficient, so that the actual filtering capacity of the filter can be obtained, namely:
wherein eta1K is the actual filtering capacity of the filter, K is the correction factor,
is the average value of TDS difference values of the water filter in a preset time, LGeneral (1)Is the total filtered water amount in a preset time.
In one embodiment, the step 206 of determining the remaining life of the filter element based on the actual filtering capacity and the preset filtering capacity may include:
obtaining the residual filterable water quantity of the filter element based on the actual filtering capacity, the preset filtering capacity and the total filtered water quantity; the remaining amount of filterable water is used to determine the remaining life of the filter element.
In one example, the amount of remaining filterable water is derived based on the following formula:
Qgeneral (1)＝(η1/η2)*LGeneral assembly
