[0002] A filter core is arranged in an electrical appliance (such as a water making device) to filter water, and the remaining life of the filter core needs to be monitored during use to ensure that the use requirements are met.

[0003] In related technologies, the remaining life of the filter core is generally attenuated by a fixed attenuation value based on the use time of the filter core. In the case of a certain time, the attenuation amount of the determined remaining life of the filter core is the same whether the filter core is used for water making or not, which can easily lead to a large deviation between the determined remaining life of the filter core and the actual remaining life of the filter core, and there is a problem of poor accuracy of the determined filter core life.

[0027] Determine the maximum water production capacity and / or maximum power-on duration corresponding to the maximum lifespan of the filter element based on the water quality parameters.

[0028] The preset water volume threshold is determined based on the maximum water production capacity and the unit lifespan decay value, and / or the preset duration threshold is determined based on the maximum power-on duration and the unit lifespan decay value.

[0045] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0047] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of this application embodiment is: a method for determining the lifespan of an appliance equipped with a filter element, the method comprising: obtaining the operating parameters of the appliance; adjusting the remaining lifespan of the filter element according to whether the operating parameters meet preset conditions; wherein, the preset conditions include the appliance being in a stopped water production state, and the lifespan decay rate of the remaining lifespan of the filter element being less than the lifespan decay rate of the remaining lifespan of the filter element when the preset conditions are met.

[0049] In this embodiment, for ease of description, the following description uses an electrical appliance as the subject of execution.

[0050] In related technologies, the remaining lifespan of a filter cartridge is typically reduced by a fixed attenuation value based on the usage time of the filter cartridge. With a fixed duration, the attenuation of the determined remaining lifespan is the same regardless of whether the filter cartridge is used for water production. This can easily lead to a large deviation between the determined remaining lifespan of the filter cartridge and the actual remaining lifespan of the filter cartridge, resulting in poor accuracy in determining the filter cartridge lifespan.

[0051] This application provides the above-mentioned solution, which is adapted to differentiate the remaining life of the filter element based on whether the operating parameters of the appliance meet the preset conditions. Specifically, based on whether the preset conditions are met, it is possible to accurately distinguish whether the filter element is used for water production. When the preset conditions are met, the life decay rate is less than when the preset conditions are not met. Therefore, the decay mode of the filter element is no longer fixed when determining the remaining life of the filter element under different usage conditions. This can reduce unnecessary decay of the remaining life of the filter element when there is no need for water production, and ensure that the determined remaining life of the filter element is more in line with the actual situation of the filter element, thereby effectively improving the accuracy of the determined remaining life of the filter element.

[0052] This application provides an electrical appliance. In this embodiment, the appliance is a water purification device, such as a direct-drinking water purifier, which does not include a water storage device. In other embodiments, the appliance may also be other devices with water filtration functions, such as cooking appliances.

[0053] In this embodiment, the electrical appliance includes a water flow channel and a filter element disposed in the water flow channel, and the filter element can filter the water flowing through the water flow channel.

[0054] The inlet of the water flow channel can be connected to an external water supply device. The filter element can filter the water flowing in from the inlet of the water flow channel, and the filtered water can flow out from the outlet of the water flow channel.

[0055] Reference Figure 1 The electrical appliance may include a water-producing load 2 located in the water flow channel. When the water-producing load 2 is turned on, the electrical appliance is in the water-producing state, and the filter element filters the water flowing through the water flow channel. When the water-producing load 2 is turned off, the electrical appliance is in the water-stopping state, and the water in the water flow channel stops flowing, and the filtering effect of the filter element stops.

[0056] The water production load 2 may include a water pump and a water outlet valve.

[0057] In one embodiment, reference is made to Figure 1The appliance may also include a trigger module 4, which has a first state and a second state. The first state represents water production, and the second state represents water production stoppage. The trigger module 4 may include a button or a detection module. When the trigger module 4 includes a button, its state can be switched by the user according to actual needs, allowing the appliance to adapt to the user's requirements by switching between water production and water production stoppage. When the trigger module 4 includes a sensor, its state can switch based on detected data, allowing the appliance to automatically switch between water production and water production stoppage states according to the detected scenario.

[0058] In one feasible implementation, refer to Figure 1 The electrical appliance also includes a water quality sensor 3. The water quality sensor 01 can be located on the water inlet side of the filter element, such as the inlet of the water flow channel, to detect the water quality of the water filtered by the filter element. In this embodiment, the water quality sensor 3 is a sensor for detecting the concentration of soluble solids.

[0059] Reference Figure 1 The electrical appliance also includes a control device 1, and the aforementioned water-producing load 2, water quality sensor 3, and trigger module 4 can be connected to the control device 1 for communication.

[0060] The control device 1 can obtain the status of the trigger module 4 and control the operation of the water production load 2 based on the status of the trigger module 4.

[0061] The control device 1 can also acquire the water quality parameters detected by the water quality sensor 3.

[0062] The control device 1 includes: at least one processor 1001; and a memory 1002 communicatively connected to the at least one processor 1001, and a timer 1003, etc.; wherein the memory 1002 stores instructions that can be executed by the at least one processor 1001, the instructions being executed by the at least one processor 1001 to enable the at least one processor 1001 to perform the filter life determination method in the following embodiment.

[0063] The following is for reference. Figure 1 The diagram illustrates a structural schematic suitable for implementing the control device 1 in the embodiments of this application. In the embodiments of this application, the control device 1, the filter element, and the aforementioned components are integrated and installed in the same body. In other implementations, while the filter element and the aforementioned components can be integrated and installed in the same body, the control device 1 can be set up independently of the body.

[0064] Figure 1 The control device 1 shown is merely an example and should not impose any limitations on the functionality and scope of use of the embodiments of this application.

[0065] like Figure 1As shown, the control device 1 may include a processor 1001 (e.g., a central processing unit, a graphics processing unit, etc.), which can perform various appropriate actions and processes according to the program stored in the memory 1002. The program in the memory 1002 may be a program in read-only memory (ROM) or a program loaded from a storage device into random access memory (RAM). The RAM also stores various programs and data required for the operation of the control device 1. The processor 1001 and the memory 1002 (ROM and RAM) are interconnected via a bus. Input / output (I / O) interfaces are also connected to the bus.

[0066] Although the figure shows a control unit 1 with various systems, it should be understood that it is not required to implement or have all of the systems shown. More or fewer systems may be implemented alternatively.

[0067] Specifically, according to the embodiments disclosed in this application, the method flow described in the following embodiments can be implemented as a computer software program. For example, the embodiments disclosed in this application include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the methods shown in the flowchart. In such embodiments, the computer program can be downloaded and installed from a network via a communication device, or installed from a storage device. When the computer program is executed by the processor 1001, it performs the functions defined in the filter life determination method of the embodiments disclosed in this application.

[0068] The electrical appliance provided in this application, employing the filter life determination method in the following embodiments, can solve the technical problem of how to improve the accuracy of the determined remaining filter life. Compared with the prior art, the beneficial effects of the electrical appliance provided in this application are the same as those of the filter life determination method provided in the following embodiments, and other technical features of the electrical appliance are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0069] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or appliance capable of performing the above functions. The following description uses an appliance as an example to illustrate this embodiment and the subsequent embodiments.

[0070] Based on this, this application provides a method for determining filter cartridge lifespan, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the filter life determination method of this application.

[0071] In this embodiment, the filter cartridge life determination method includes steps S10 to S20:

[0072] Step S10: Obtain the operating parameters of the electrical appliance;

[0073] In this embodiment, step S10 is executed when the electrical appliance is powered on.

[0074] In one implementation, the operating parameters may include a first state parameter indicating whether the appliance is in a water-producing state.

[0075] In another implementation, in addition to the first state parameter, the operating parameters may also include at least one of the following: the duration of the appliance being in the water-stopping state, the current lifespan of the filter element when the appliance is in the water-stopping state, the water quality state parameters when the appliance is in the water-stopping state, etc.

[0076] The methods by which electrical appliances can start water production include, but are not limited to: touch buttons, high-pressure switch sensors, Hall effect sensors, capacitive sensors, etc.

[0077] Step S20: Adjust the remaining lifespan of the filter element according to whether the operating parameters meet the preset conditions;

[0078] The preset conditions include the appliance being in a stopped water production state, and the life decay rate of the filter element when the preset conditions are met is less than the life decay rate of the filter element when the preset conditions are not met.

[0079] Regardless of whether preset conditions are met, the lifespan decay rate is greater than or equal to 0. This means that adjusting the remaining lifespan can include one of the following: stopping the remaining lifespan update, updating the remaining lifespan, etc. Here, remaining lifespan update refers to remaining lifespan decay. In one case, the remaining lifespan of the filter element is stopped when the preset conditions are met, and updated when the preset conditions are not met; in another case, the remaining lifespan of the filter element decays both when the preset conditions are met and when they are not met. The lifespan decay rate can represent the time required for the remaining lifespan of the filter element to decrease by one unit of lifespan decay value. In either of the above cases, the time required for the remaining lifespan of the filter element to decrease by one unit of lifespan decay value when the preset conditions are met is greater than the time required for the remaining lifespan of the filter element to decrease by one unit of lifespan decay value when the preset conditions are not met. Maintaining the current remaining lifespan can be achieved indefinitely.

[0080] In one implementation, the target lifespan decay condition can be determined based on whether the operating parameters meet preset conditions. When the actual usage parameters of the filter element meet the target lifespan decay condition, the remaining lifespan of the filter element is updated according to the unit lifespan decay value. Specifically, when the operating parameters meet the preset conditions, the first lifespan decay condition can be determined as the target lifespan decay condition; when the operating parameters do not meet the preset conditions, the second lifespan decay condition can be determined as the target lifespan decay condition. The time required for the actual usage parameters to reach the first lifespan decay condition is longer than the time required for the actual usage parameters to reach the second lifespan decay condition. In other words, the decay rate of the filter element is slower when the preset conditions are met than when the preset conditions are not met.

[0081] In another implementation, the remaining lifespan of the filter element can be determined based on whether the operating parameters meet preset conditions. When the operating parameters meet the preset conditions, updating the current remaining lifespan of the filter element stops (i.e., the remaining lifespan of the filter element remains unchanged); when the operating parameters do not meet the preset conditions, the remaining lifespan of the filter element is updated based on the actual usage status parameters of the filter element.

[0082] In another implementation, the target lifespan decay value is determined based on whether the operating parameters meet preset conditions. Regardless of whether the operating parameters meet the preset conditions, the remaining lifespan of the filter element is updated according to the target lifespan decay value when the actual usage parameters meet the lifespan decay conditions. Specifically, when the operating parameters meet the preset conditions, the first decay value is the target lifespan decay value; when the operating parameters do not meet the preset conditions, the second decay value is the target lifespan decay value. The first decay value is less than the second decay value. In other words, when the same lifespan decay conditions are met, the lifespan decay value when the preset conditions are met is less than the lifespan decay value when the preset conditions are not met.

[0083] This embodiment provides a method for determining filter cartridge lifespan, which is adapted to differentiate the remaining lifespan of the filter cartridge based on whether the operating parameters of the appliance meet preset conditions. The method can accurately distinguish whether the filter cartridge is used for water production based on whether the preset conditions are met. When the preset conditions are met, the lifespan decay rate is less than when the preset conditions are not met. Therefore, the decay mode of the filter cartridge is no longer fixed when determining the remaining lifespan under different usage conditions. This can reduce unnecessary decay of the remaining lifespan of the filter cartridge when there is no need for water production, and ensure that the determined remaining lifespan of the filter cartridge is more in line with the actual situation of the filter cartridge, thereby effectively improving the accuracy of the determined remaining lifespan of the filter cartridge.

[0084] In one feasible implementation, the preset conditions include at least one of the following:

[0085] Condition 1: The electrical appliance is in a stopped water production state and the duration is greater than or equal to the first duration;

[0086] Condition 2: The appliance is in a stopped water production state and the duration is less than or equal to the upper limit duration, wherein the upper limit duration is greater than the first duration;

[0087] Condition 3: The electrical appliance is in a stopped water production state and the current remaining lifespan of the filter element is greater than the preset lifespan.

[0088] In condition 1, the first duration can be a pre-set fixed duration (e.g., 3 days), or it can be a duration determined based on the actual situation of the appliance. For example, the first duration can be determined based on the current remaining lifespan of the filter cartridge and / or the water quality parameters of the water flow channel detected at the initial moment when the appliance stops producing water. Meeting condition 1 indicates that the filter cartridge does not require water production. Based on this, the preset condition, including condition 1, ensures that the remaining lifespan of the filter cartridge can be adjusted to accommodate the presence or absence of water production needs, thereby effectively improving the certainty of the remaining lifespan.

[0089] In condition 2, the upper limit duration can be a pre-set fixed duration or determined based on the actual condition of the filter element. In this embodiment, the upper limit duration can be determined based on the standard lifespan of the filter element. The product of the standard lifespan of the filter element and a preset percentage is the upper limit duration. The preset percentage can be [10%, 30%] of the standard lifespan of the filter element, for example, 20%. The standard lifespan of the filter element is the maximum lifespan of the filter element obtained based on tests under standard operating conditions. In other embodiments, the upper limit duration can also be determined based on the actual water quality parameters detected in the water flow channel at the initial moment when the appliance is in water production mode and / or the number of times the filter element cleaning operation is performed under preset conditions. The upper limit duration can be negatively correlated with the degree of water contamination represented by the actual water quality parameters. Since the filter element is also soaked in water when not used for water production, different soaking times will have different effects on the lifespan reduction of the filter element. The preset conditions, including condition 2, are beneficial to further improve the accuracy of the remaining lifespan of the filter element.

[0090] In condition 3, the preset lifespan is a pre-set lifespan threshold. The critical lifespan used to distinguish whether a filter element has a risk of failure can be set as the preset lifespan. For example, if the remaining lifespan is less than the preset lifespan, the filter element has a risk of failure; if the remaining lifespan is greater than or equal to the preset lifespan, the filter element does not have a risk of failure. Based on condition 3, the above operating parameters may also include the current remaining lifespan of the filter element. Since the risk of failure varies depending on the remaining lifespan of the filter element, the preset condition further includes condition 3. This helps ensure that the filter element failure time corresponding to the remaining lifespan is earlier than or equal to the actual failure time of the filter element, thus ensuring the accuracy of the remaining lifespan and guaranteeing that the normal water demand of electrical appliances can be met based on the remaining lifespan.

[0091] In this embodiment, the preset conditions include condition 1, condition 2, and condition 3. If the first state parameter in the operating parameters is in the water production state, it can be considered that the preset conditions are not met. If the first state parameter in the operating state parameters is in the stopped water production state, it can be first determined whether condition 1 is met; if condition 1 is not met, it can be considered that the preset conditions are not met. If condition 1 is met, it can be further determined whether condition 2 is met; if condition 2 is not met, it can be considered that the preset conditions are not met. If condition 2 is met, it can be further determined whether condition 3 is met; if condition 3 is not met, it can be considered that the preset conditions are not met, and if condition 3 is met, it can be considered that the preset conditions are met.

[0092] In other embodiments, the preset condition may also be that the appliance is in a state of stopping water production.

[0093] In one feasible implementation, step S20 includes: stopping the update of the current remaining lifespan of the filter element when the operating parameters meet the preset conditions; and updating the current remaining lifespan of the filter element according to the actual usage status parameters of the filter element when the operating parameters do not meet the preset conditions.

[0094] Actual usage status parameters refer to the actual status parameters of the appliance indicating the lifespan consumption of the filter element. Actual usage status parameters may include at least one of the following: the duration of water production, the cumulative power-on time of the appliance, the cumulative water production of the filter element, etc.

[0095] In one implementation, the actual usage state parameter can be a state parameter within a target duration when a preset condition is not met. The target duration is the time period from the initial moment when the preset condition is not met to the current moment, or the time period from the moment when the filter element's remaining lifespan decreased last time when the preset condition is not met to the current moment. Based on this, if the actual usage state parameter meets the lifespan decay condition, the lifespan decay value corresponding to the lifespan decay condition can be determined to reduce the current remaining lifespan of the filter element. In another implementation, the state parameter can also be a state parameter representing the total lifespan consumption of the filter element from the initial moment when the filter element is put into use (at which time the lifespan of the filter element can be considered as the maximum lifespan) to the current moment when the preset condition is not met. In this case, the total lifespan consumption can be determined based on the actual usage state parameter, and the difference between the maximum lifespan of the filter element and the total lifespan consumption is determined as the remaining lifespan of the filter element.

[0096] In this embodiment, the filter cartridge's lifespan stops decreasing when the appliance's operating parameters meet preset conditions; when the appliance's operating parameters do not meet preset conditions, the filter cartridge's lifespan decreases according to the filter cartridge's actual usage. This helps reduce unnecessary lifespan decreases when the filter cartridge is not used for water production; otherwise, the remaining lifespan is normally decreased according to the filter cartridge's actual usage parameters, thus effectively improving the accuracy of the determined remaining lifespan.

[0097] In one feasible implementation, after the step of stopping updating the current remaining lifespan of the filter element when the operating parameters meet the preset conditions, the method further includes: if the appliance does not meet the end conditions of the filter element, returning to the step of obtaining the operating parameters of the appliance; and / or, if the appliance meets the end conditions of the filter element, updating the current remaining lifespan of the filter element according to the actual usage status parameters of the filter element; wherein the end conditions include at least one of the following:

[0098] Condition 4: The duration during which the electrical appliance is in a water-stopping state is greater than the upper limit duration;

[0099] Condition 5: The electrical appliance is in water production mode.

[0100] In this embodiment, the termination condition is considered met when either condition 4 or condition 5 is satisfied. When condition 4 is satisfied, the filter cartridge lifespan resumes normal decline, preventing the filter cartridge lifespan from ceasing to decline for an extended period. When condition 5 is satisfied, the filter cartridge lifespan resumes normal decline, ensuring that the filter cartridge lifespan decline accurately matches the actual lifespan consumption of the filter cartridge during water production. If neither condition 4 nor condition 5 is satisfied, and the re-acquired operating parameters meet the aforementioned preset conditions, the filter cartridge lifespan continues to stop declining. If neither condition 4 nor condition 5 is satisfied, and the re-acquired operating parameters do not meet the aforementioned preset conditions, the filter cartridge lifespan resumes normal decline.

[0101] In this embodiment, the above method helps to further improve the accuracy of the determined remaining lifespan of the filter element.

[0102] In other embodiments, the termination condition may also include receiving a water usage instruction from the appliance or the termination condition may also include the water storage volume in the appliance being less than a preset water volume.

[0103] In other embodiments, the current remaining lifespan of the filter element may be stopped if the appliance does not meet the end conditions of the filter element.

[0104] In other embodiments, if the appliance meets the filter cartridge's termination conditions, the current remaining lifespan of the filter cartridge can be reduced according to a preset lifespan decay value, and then the current remaining lifespan of the filter cartridge can be updated according to the actual usage parameters of the filter cartridge. The preset lifespan decay value is less than the unit lifespan decay value.

[0105] In one feasible implementation, after updating the current remaining lifespan of the filter element based on its actual usage parameters when the operating parameters do not meet the termination condition, or when the appliance meets the termination condition, the process further includes: returning to the step of obtaining the operating parameters of the appliance. Based on this, when the operating parameters do not meet the preset conditions, the remaining lifespan of the filter element can be adapted to gradually decrease according to the actual usage parameters.

[0106] In one feasible implementation, the step of updating the current remaining lifespan of the filter element based on its actual usage status parameters includes:

[0107] Obtain the actual usage status parameters of the filter element within a target duration; if the actual usage status parameters meet the lifespan decay condition, reduce the current remaining lifespan of the filter element according to the unit lifespan decay value, where the target duration is the time period from the initial moment when the preset condition is not met to the current moment, or the time period from the moment when the remaining lifespan of the filter element was last reduced when the preset condition is not met to the current moment.

[0108] In this embodiment, the maximum lifespan or standard lifespan of the filter element is expressed as 100%, and the unit lifespan attenuation can be 1%.

[0109] The lifespan decay condition is the condition that the actual usage parameters must meet when the remaining lifespan decay of the filter element is equal to the unit lifespan decay value. The lifespan decay condition is adapted to be set to match the unit lifespan decay value. In this embodiment, the lifespan decay condition includes: the cumulative water production reaching a preset water production threshold, and / or, the cumulative power-on time reaching a preset duration threshold.

[0110] The preset water volume threshold and preset duration threshold can be fixed values ​​set in advance, or parameter values ​​determined according to the actual situation of the appliance. Both the preset water volume threshold and the preset duration threshold are parameters corresponding to the unit lifespan decay value. The preset water volume threshold is 1% of the maximum water production capacity of the filter element or the standard water production capacity of the filter element, and the preset duration threshold is 1% of the maximum power-on duration of the filter element or the standard power-on duration of the filter element.

[0111] In the process of cyclically reducing the current remaining lifespan of the filter element based on the actual usage status parameters within the target duration, if the working parameters do not meet the preset conditions, the first target duration is the time period from the initial moment when the preset conditions were not met to the current moment; the subsequent target durations are the time period from the moment when the remaining lifespan of the filter element was last reduced when the preset conditions were not met to the current moment.

[0112] In this embodiment, the remaining lifespan of the appliance can be precisely matched with the actual lifespan of the filter element through the above method, thereby effectively improving the accuracy of the determined remaining lifespan of the filter element.

[0113] In one feasible implementation, the filter cartridge life determination method further includes: obtaining water quality parameters of the water treated by the filter cartridge within the target duration; determining the maximum water production and / or maximum power-on duration corresponding to the maximum lifespan of the filter cartridge based on the water quality parameters; determining the preset water volume threshold based on the maximum water production and the unit lifespan decay value; and / or determining the preset duration threshold based on the maximum power-on duration and the unit lifespan decay value.

[0114] In this embodiment, water quality parameters include soluble solids concentration (TDS), etc.

[0115] Water quality parameters can be detected at the initial moment of the target duration. In this embodiment, water quality parameters may include those on the inlet and / or outlet sides of the filter cartridge.

[0116] In this embodiment, the maximum water production capacity corresponding to the standard lifespan of the filter cartridge is the standard water production capacity, and the maximum power-on time corresponding to the standard lifespan of the filter cartridge is the standard power-on time. The maximum water production capacity is obtained by dynamically adjusting the standard water production capacity according to the water quality parameters, and the maximum power-on time is obtained by dynamically adjusting the standard power-on time according to the water quality parameters.

[0117] In this embodiment, the maximum water production and / or maximum power-on duration are negatively correlated with TDS.

[0118] In this embodiment, the unit lifespan decay value is the unit lifespan decay ratio. Therefore, the product of the maximum water production capacity and the unit lifespan decay ratio is the preset water volume threshold, and the product of the maximum power-on time and the unit lifespan decay ratio is the preset duration threshold. In other implementations, the unit lifespan decay value can also be the unit lifespan decay amplitude. In this case, the ratio between the unit lifespan decay value and the standard lifespan of the filter cartridge can be determined, and the product of the maximum water production capacity and the ratio is used as the preset water volume threshold, and the product of the maximum power-on time and the ratio is used as the preset duration threshold.

[0119] In this embodiment, by adopting the above method, the impact of water quality on the lifespan of the filter element is accurately considered, which helps to further improve the accuracy of the determined remaining lifespan of the filter element.

[0120] In other embodiments, the preset water volume threshold can also be the product of the unit lifespan decay ratio and the standard water production volume, and the preset duration threshold can also be the product of the unit lifespan decay ratio and the standard power-on duration.

[0121] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, after step S10, the method further includes:

[0122] When the operating parameters meet the preset conditions, the filter element is cleaned every second time interval.

[0123] In this embodiment, the filter element is cleaned every second time interval while maintaining the current remaining lifespan of the filter element.

[0124] Cleaning operations may include at least one of the following: backwashing, vacuum cleaning, etc.

[0125] The second duration can be a preset fixed duration, such as 3 days; or, the second duration can also be determined according to the actual situation of the appliance, such as the water quality parameters in the water flow channel detected at the initial moment when the working parameters meet the preset conditions (including the water quality parameters on the filter element inlet side and / or the filter element outlet side) and / or the interval between the current moment and the moment when the filter element last performed a cleaning operation and / or the duration of the stop water production state, etc.

[0126] In this embodiment, during the process of the filter cartridge life stopping at a second time interval, the filter cartridge is cleaned to maintain its cleanliness. This is beneficial to ensure the cleanliness of the water filtered by the filter cartridge when the water production is restored. On the other hand, it can reduce the filter cartridge life reduction caused by dirt caused by prolonged soaking in water, thereby further improving the accuracy of the determined remaining life of the filter cartridge.

[0127] In other embodiments, the cleaning operation may not be performed during the process of the filter cartridge lifespan ceasing to decline, or the cleaning operation may be performed in response to user instructions.

[0128] For example, in order to help understand the implementation process of the filter life determination method involved in the embodiments of this application, combined with Figure 3 and Figure 4 The process of an application example of the method for determining filter cartridge life is introduced:

[0129] Step S00: Power on the appliance;

[0130] After the appliance is powered on, it initializes: all water production loads are turned off, and the current remaining lifespan of the filter cartridge is read.

[0131] After the electrical appliances are initialized, step S01 can be executed.

[0132] Step S01: Obtain the current operating parameters of the electrical appliance and determine whether the operating parameters meet the preset conditions;

[0133] If the working parameters meet the preset conditions, proceed to step S02; if the working parameters do not meet the preset conditions, proceed to step S03.

[0134] Step S02: Maintain the current remaining lifespan of the filter element and perform a cleaning operation on the filter element every second time interval.

[0135] Step S01 is executed after step S02.

[0136] Step S03: Obtain the water quality parameters of the water treated by the filter cartridge within the target time period, as well as the cumulative water production and / or cumulative power-on time of the filter cartridge within the target time period;

[0137] Step S04: Determine the maximum water production capacity and / or maximum power-on time of the filter cartridge based on water quality parameters, and determine 1% of the maximum water production capacity as the preset water production capacity threshold and / or determine 1% of the maximum power-on time as the preset time threshold; wherein, 1% is the unit lifespan decay value;

[0138] Step S05: Determine whether the cumulative water production reaches 1% of the maximum water production and / or whether the cumulative power-on time reaches 1% of the maximum power-on time.

[0139] If the cumulative water production reaches 1% of the maximum water production and / or the cumulative power-on time reaches 1% of the maximum power-on time, execute step S06 and then execute step S01; if the cumulative water production does not reach 1% of the maximum water production and the cumulative power-on time does not reach 1% of the maximum power-on time, return to execute step S01.

[0140] Step S06: The current remaining lifespan of the filter element is reduced by 1%.

[0141] The process of step S01 is as follows:

[0142] Step S011: Determine whether the operating parameters include being in a stopped water production state;

[0143] If the operating parameters do not include a state where water production is stopped, proceed to step S015; if the operating parameters include a state where water production is stopped, proceed to step S012.

[0144] Step S012: Determine whether the duration of the water production stoppage in the working parameters is greater than or equal to the first duration.

[0145] If the duration is greater than or equal to the first duration, proceed to step S013; if the duration is less than the first duration, proceed to step S015.

[0146] Step S013: Determine whether the duration of the water production stoppage in the working parameters is less than or equal to the upper limit duration.

[0147] If the duration is less than or equal to the upper limit, proceed to step S014; if the duration is greater than the upper limit, proceed to step S015.

[0148] Step S014: Determine whether the current remaining lifespan of the filter element in the working parameters is greater than the preset lifespan;

[0149] If the remaining lifespan is greater than the preset lifespan, proceed to step S016; if the remaining lifespan is less than or equal to the preset lifespan, proceed to step S105.

[0150] Step S015, the preset conditions were not met;

[0151] Step S016: The preset conditions are met.
