[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0031] After long-term operation, the filter of the air conditioner is prone to dust accumulation. When the dust accumulates to a certain extent, the filter may be dirty and blocked, which may lead to problems such as air volume attenuation and performance degradation of the air conditioner. At the same time, with the accumulation of dust, bacteria, mold, etc. will grow on the filter, which will also lead to problems such as poor air supply quality. In order to clean the dirty and blocked filter in time, it is possible to judge whether the filter is dirty and blocked. However, the judgment method of the related technology is relatively rough, that is, it is limited to whether it is dirty and blocked. However, the dirty and blocked conditions that different users can tolerate may be different. For example, the judgment method in the related technology judges that the air conditioner filter is dirty and blocked. For some users, the degree of dirty and blocked of this air conditioner filter can be tolerated, and the filter will not be cleaned according to the judgment result of the air conditioner. Or, for another part of the users, when it is judged to be dirty and blocked, the dirty and blocked condition of the filter is already quite serious, resulting in the air conditioner filter not being cleaned in time. Therefore, a more detailed judgment method is urgently needed to facilitate users to understand the specific situation of dirty and blocked, so that users can clean the air conditioner filter in time.

[0032] In view of the above problems, the inventor has found through long-term research that when the air conditioner is in the same gear, the air conditioner fan speed is fixed. Compared with the case where the air conditioner filter is not dirty and blocked, when the air conditioner filter is dirty and blocked, the wind resistance increases and the air volume decreases accordingly. Then the resistance overcome by the fan decreases accordingly, and the fan load also decreases accordingly. Since the fan load is reduced, the power is reduced, and the change in power can be reflected by the change in the duty cycle (Pulse Width Modulation, PWM). Therefore, the specific degree of dirty and blocked air conditioner filter can be judged by monitoring the duty cycle of the air conditioner fan. Based on this, the inventor proposes a method, device, electronic device and medium for detecting dirty and blocked air conditioner filter. First, the working duty cycle of the air conditioner fan is obtained, and then the judgment parameter is obtained according to the preset duty cycle and the working duty cycle, and then the specific degree of dirty and blocked air conditioner filter is determined according to the judgment parameter, so that the user can clean the air conditioner filter according to the degree of dirty and blocked air conditioner filter. Among them, the specific method for detecting dirty and blocked air conditioner filter is described in the subsequent embodiments.

[0033] This disclosure provides a method for detecting dirty and blocked air conditioner filters. Figure 1 The air conditioning filter dirty blockage detection method can be applied to Figure 3 The air conditioning filter dirty blockage detection device 200 shown, Figure 4 The air conditioning filter dirty blockage detection device 300 and the computer readable storage medium shown in the embodiment are applied to Figure 4 The air conditioning filter dirty blockage detection device 300 shown in the figure is taken as an example, wherein Figure 4 The air conditioner filter dirty blockage detection device 300 shown can be an air conditioner, or an electronic device connected to the air conditioner, for example, the electronic device can be a mobile terminal, a tablet computer, a computer, a server, etc. Figure 1The process shown in the figure is described in detail, and the air conditioning filter dirty blockage detection method can specifically include the following steps:

[0034] Step S110, obtaining the duty cycle of the air conditioner fan.

[0035] After the user turns on the air conditioner, the working duty cycle of the air conditioner fan is obtained. In one embodiment, after the air conditioner is turned on, the user sets the operating parameters on the control panel of the air conditioner, and the air conditioner enters the duty cycle detection mode. In the duty cycle detection mode, the air conditioner works according to the preset parameters, and the duty cycle of the air conditioner fan in this mode is collected, and the duty cycle is the working duty cycle. After obtaining the working duty cycle, the air conditioner exits the duty cycle detection mode and then works according to the operating parameters set by the user.

[0036] Optionally, the preset operating parameters may include at least one of the following: a preset windshield for adjusting the gear of the air-conditioning fan, a preset angle for adjusting the angle of the air guide plate, and a preset duration for controlling the duration of the duty cycle detection mode.

[0037] Optionally, the timing of the air conditioner entering the duty cycle detection mode is not limited to the above method, that is, it is not limited to entering the duty cycle detection mode after the air conditioner is turned on. It can also be entered at any stage during the operation of the air conditioner. For example, after the air conditioner starts to run for a preset time, the air conditioner has run stably, and then enters the duty cycle detection mode to obtain the working duty cycle, where the preset time can be, but is not limited to, 5 minutes, 6 minutes, 10 minutes, etc.

[0038] Step S120: obtaining a difference between a preset duty cycle and the working duty cycle as a first difference, and obtaining a determination parameter according to a ratio between the first difference and the preset duty cycle.

[0039] The preset duty cycle can be the duty cycle of the air conditioner fan collected when the air conditioner filter is not dirty or blocked. In order to improve the accuracy of the judgment of the degree of dirtiness and blockage and reduce the interference of other factors, the acquisition conditions of the preset duty cycle and the working duty cycle can be kept consistent. For example, the preset duty cycle of the air conditioner fan is obtained in the duty cycle detection mode.

[0040] The judgment parameter can be obtained as shown in formula (1):

[0041]

[0042] Among them, γ is the decision parameter, P 1 is the duty cycle, P 2 is the preset duty cycle.

[0043] As analyzed above, when the air conditioning filter is clogged, the fan power is reduced and the duty cycle is also reduced. Based on formula (1), when the air conditioning filter is not clogged, the judgment parameter is 0. The more serious the air conditioning filter is clogged, the larger the judgment parameter may be.

[0044] The preset duty cycle and the working duty cycle are used to obtain a determination parameter for determining the degree of dirtiness and blockage. The determination parameter is not limited to that shown in step S120. The determination parameter may be the difference between the preset duty cycle and the working duty cycle, or the ratio between the working duty cycle and the preset duty cycle.

[0045] Optionally, the difference between the first preset duty cycle and the working duty cycle may be obtained, and the determination parameter may be obtained according to the ratio between the difference and the second preset duty cycle. The first preset duty cycle may be the duty cycle of the air conditioner fan obtained when the air conditioner filter is not dirty or blocked, and the second preset duty cycle may be an arbitrary duty cycle. In this embodiment, the size of the determination parameter may be positively correlated with the degree of dirtiness or blockage.

[0046] Alternatively, the determination parameter may be obtained based on the ratio between the preset duty cycle and the working duty cycle. The magnitude of the determination parameter may be positively correlated with the degree of dirtiness and blockage.

[0047] Alternatively, a determination parameter may be obtained based on the difference between the preset duty cycle and the working duty cycle. The magnitude of the determination parameter may be positively correlated with the degree of dirtiness and blockage.

[0048] Step S130: Determine the degree of dirtiness and blockage of the air conditioning filter according to the determination parameter.

[0049] Exemplarily, the degree of dirtiness can be divided into "clean", "slightly dirty", "generally dirty" and "severely dirty". Alternatively, the degree of dirtiness can be divided into "level one dirty", "level two dirty", "level three dirty" and "level four dirty", wherein the degree of dirtiness can become more serious as the level of dirtiness increases, and the more serious the degree of dirtiness, the more dust accumulates on the air conditioner filter. According to the determination parameter, the determined degree of dirtiness is one of the above degrees of dirtiness.

[0050] Step S140: obtaining a detection interval according to the dirtiness and blockage degree, so as to perform a next dirtiness and blockage degree detection according to the detection interval.

[0051] The detection interval is not fixed, and may be changed according to the current degree of dirtiness and congestion. The more serious the degree of dirtiness and congestion, the higher the detection interval. In one embodiment, a preset corresponding relationship is established in advance, wherein the preset corresponding relationship includes the corresponding relationship between the degree of dirtiness and congestion and the detection interval, and the detection interval is obtained according to the preset corresponding relationship and the degree of dirtiness and congestion. Exemplarily, the preset corresponding relationship includes: a first detection interval corresponding to a degree of dirtiness and congestion of "clean", a second detection interval corresponding to a degree of dirtiness and congestion of "slightly dirty", a third detection interval corresponding to a degree of dirtiness and congestion of "generally dirty", and a fourth detection interval corresponding to a degree of dirtiness and congestion of "severely dirty". The first detection interval is greater than or equal to the second detection interval, the second detection interval is greater than or equal to the third detection interval, and the third detection interval is greater than the fourth detection interval. For example, the first detection interval is 15 days, the second detection interval is 12 days, the third detection interval is 6 days, and the fourth detection interval is 3 days.

[0052] In another embodiment, the current filter coefficient is obtained according to the degree of dirtiness and blockage; the intermediate parameter is obtained according to the product between the preset detection interval and the preset number of times; and the detection interval is obtained according to the quotient between the intermediate parameter and the current filter coefficient. As shown in the following formula:

[0053] t1=(t2*n) / k;

[0054] Among them, t1 is the detection interval, t2 is the preset detection interval, t2 can be set to the cumulative running time of the air conditioner for 24 hours, n is the preset number of times, n can be set to 4, and k is the current filter coefficient. The value of the filter coefficient can be referred to as shown in Table 1 below:

[0055] Table 1

[0056] Dirt and blockage degree State 1 State 2 State 3 State 4 k k1 k2 k3 k4

[0057] Optionally, in Table 1, k1 = 1, k2 = 2, k3 = 3, k4 = 4. Taking t2 = 24h and n = 4 as an example, when the dirty blockage degree is dirty blockage represented by state 1, combined with the above formula, the detection interval t1 is 96 hours.

[0058] The detection interval is set based on the accumulated running time of the air-conditioning fan or based on a natural day.

[0059] The degree of dirtiness and blockage is inversely correlated with the detection interval. It is understandable that the cleaner the air conditioning filter is, the longer the detection interval is, and the dirtier and more blocked the air conditioning filter is, the shorter the detection interval is.

[0060] The method for detecting the dirty and blocked air conditioning filters provided in the present embodiment first obtains the working duty cycle of the air conditioning fan, then obtains the difference between the preset duty cycle and the working duty cycle as the first difference, obtains the judgment parameter according to the ratio between the first difference and the preset duty cycle, and then determines the specific degree of dirty and blocked air conditioning filters according to the judgment parameter, obtains the detection interval according to the degree of dirty and blocked air conditioning filters, so as to facilitate the next dirty and blocked air conditioning filter detection according to the detection interval. Different users have different tolerance levels for dirty and blocked air conditioning filters, so as to facilitate users to understand the specific degree of dirty and blocked air conditioning filters. Each user can decide the time to clean the air conditioning filter according to the specific degree of dirty and blocked air conditioning filters, so that the air conditioning filter can be cleaned in time. The detection interval can be flexibly set according to the degree of dirty and blocked air conditioning filters, so as to facilitate the next dirty and blocked air conditioning filter detection according to the detection interval, so that the degree of dirty and blocked air conditioning filters can be detected in time.

[0061] Optionally, the air conditioner dirtiness and blockage detection may be performed after the air conditioner is turned on for the first time that day.

[0062] In one embodiment, step S130 may include the following steps: determining the parameter interval to which the judgment parameter belongs; determining the degree of dirtiness and blockage of the air-conditioning filter according to a preset mapping relationship and the parameter interval, wherein the preset mapping relationship includes a corresponding relationship between the parameter interval and the degree of dirtiness and blockage.

[0063] A plurality of parameter intervals are pre-divided to determine the parameter interval to which the judgment parameter belongs. A preset mapping relationship is pre-established, and optionally, the preset mapping relationship may be in the form of a relationship mapping table, as shown in Table 1:

[0064] Table 2

[0065] Parameter range [0, γ1) [γ1,γ2) [γ2,γ3) [γ3, 1) Dirt and blockage degree clean Slightly dirty General dirty blockage Severe dirt blockage

[0066] Exemplarily, it is determined that the parameter γ is in the parameter interval [γ1, γ2). Combined with Table 2, the degree of dirtiness and blockage is slight dirtiness and blockage.

[0067] In this embodiment, multiple parameter intervals are pre-set, and each parameter interval corresponds to a degree of dirtiness and blockage. By setting multiple parameter intervals and multiple degrees of dirtiness and blockage, the judgment of dirtiness and blockage is refined to a specific degree of dirtiness and blockage, which facilitates the user to clean the air conditioning filter in time according to the degree of dirtiness and blockage.

[0068] In another embodiment, see Figure 2 , step S130 may include the following steps:

[0069] Step S131: Determine the filter status of the air conditioning filter according to the determination parameter.

[0070] As a method, determine the parameter interval to which the judgment parameter belongs; determine the filter state of the air-conditioning filter based on a first mapping relationship and the parameter interval, wherein the first mapping relationship includes a corresponding relationship between the parameter interval and the filter state.

[0071] A first mapping relationship is pre-established. Optionally, the first mapping relationship may be in the form of a relationship mapping table, as shown in Table 3:

[0072] Table 3

[0073] Parameter range [0, γ1) [γ1,γ2) [γ2,γ3) [γ3, 1) Filter status State 1 State 2 State 3 State 4

[0074] Exemplarily, the judgment parameter γ is in the parameter interval [γ1, γ2). Combined with Table 3, the filter state corresponding to the judgment parameter is state 2.

[0075] For example, γ1 is 2%, γ2 is 4%, and γ3 is 6%.

[0076] Step S132: Determine the degree of dirtiness and blockage of the air conditioning filter according to the filter status.

[0077] As a method, the degree of dirtiness and blockage of the air conditioning filter is determined based on a second mapping relationship and the filter status, wherein the second mapping relationship includes a corresponding relationship between the filter status and the degree of dirtiness and blockage.

[0078] Similarly, a second mapping relationship is pre-established. Optionally, the second mapping relationship may be in the form of a relationship mapping table, as shown in Table 4:

[0079] Table 4

[0080] Filter status State 1 State 2 State 3 State 4 Dirt and blockage degree clean Slightly dirty General dirty blockage Severe dirt blockage

[0081] Continuing with the above example, according to Table 4, the filter state is state 2, and its corresponding degree of dirtiness and blockage is slight dirtiness and blockage.

[0082] Optionally, when using the air conditioner, affected by factors such as weather changes and different habits of using air conditioners by different family members, if the duty cycle obtained under different factors is directly used to judge the dirty blockage, the error rate of the dirty blockage degree may be high. Therefore, the duty cycle collected under different factors is standardized by a standardized formula to improve the accuracy of the dirty blockage degree judgment. For example, the preset duty cycle is obtained in the following manner: the initial duty cycle of the air conditioner fan is obtained. Optionally, the initial duty cycle can be collected when the air conditioner is used for the first time after the air conditioner is installed. Exemplarily, when the air conditioner works for the first time, the air conditioner is controlled to enter the duty cycle detection mode, and the initial duty cycle is collected in this mode. And the initial duty cycle is processed by a standardized formula to obtain the preset duty cycle. Exemplarily, the following processing is performed by a standardized formula: the first standardized difference corresponding to the initial duty cycle is obtained. According to the sum of the initial duty cycle and the first standardized difference, the preset duty cycle is obtained, which can be that the sum of the initial duty cycle and the first standardized difference is calculated to obtain the preset duty cycle.

[0083] As a method, the first standardized difference is obtained in the following manner: obtaining a first air-conditioning parameter corresponding to the initial duty cycle, the first air-conditioning parameter can be understood as the parameter of the air conditioner when the initial duty cycle of the air conditioner is obtained; then obtaining the difference between the standard parameter and the first air-conditioning parameter as the second difference, and obtaining the first standardized difference based on the second difference and the correction coefficient, which can be to calculate the product between the second difference and the correction coefficient to obtain the first standardized difference.

[0084] Optionally, the first air conditioning parameter includes the ambient temperature and / or the input voltage of the air conditioning fan. The correction coefficient corresponds to the aforementioned air conditioning parameter, for example, when the first air conditioning parameter includes the ambient temperature, the correction coefficient includes the temperature correction coefficient, and when the first air conditioning parameter includes the input voltage, the correction coefficient includes the voltage correction coefficient.

[0085] For example, taking the first air conditioning parameter including the ambient temperature and the input voltage of the air conditioning fan as an example, the first standardized difference includes the first temperature standardized difference and the first voltage standardized difference. The first ambient temperature of the air conditioner is obtained; the difference between the standard temperature and the first ambient temperature is obtained as the second difference, and the first temperature standardized difference is obtained according to the second difference and the temperature correction coefficient. Optionally, the first temperature standardized difference can be the product of the second difference and the temperature correction coefficient; the first input voltage of the air conditioning fan is obtained; the difference between the standard voltage and the first input voltage is obtained as the third difference, and the first voltage standardized difference is obtained according to the third difference and the voltage correction coefficient. Optionally, the first voltage standardized difference can be the product of the third difference and the voltage correction coefficient.

[0086] Among them, the standardized formula can be expressed by the following formula:

[0087] P standardization = P to be standardized + λ 1 *(T 1 -T to be standardized)+λ 2 *(U 1 -U to be standardized)(2)

[0088] In formula (2), Pstandardized is the duty cycle after standardization, Pto be standardized is the duty cycle to be standardized, which can be understood as the directly collected duty cycle, λ 1 is the temperature correction factor, T 1 is the standard temperature, Tto be standardized is the indoor ambient temperature of the air conditioner when Pto be standardized is collected, λ 2 is the voltage correction factor, U 1 is the standard voltage, Uto be standardized is the input voltage of the air conditioner when Pto be standardized is collected.

[0089] Combining formula (2) to obtain the following formula (3), the preset duty cycle can be obtained by the following formula (3):

[0090] P 2 =P 3 +λ 1 *(T 1 -T 2 )+λ 2 *(U 1 -U 2 ) (3)

[0091] Among them, P 2 is the preset duty cycle, P 3 is the initial duty cycle, λ 1 is the temperature correction factor, T 1 is the standard temperature, T 2 is the first ambient temperature, λ 2 is the voltage correction factor, U 1 is the standard voltage, U 2 is the first input voltage.

[0092] It can be understood that, by performing the above-mentioned standardization processing on the initial duty cycle, it is equivalent to processing the initial duty cycle as the duty cycle under the first air-conditioning parameter (ie, the preset duty cycle).

[0093] Step S110 includes the following method: obtaining the actual duty cycle of the air conditioner fan, and processing the actual duty cycle through the standardized formula to obtain the working duty cycle of the air conditioner fan. Exemplarily, the following processing is performed through the standardized formula: obtaining a second standardized difference corresponding to the actual duty cycle; and then obtaining the working duty cycle of the air conditioner fan according to the sum of the actual duty cycle and the second standardized difference.

[0094] As a method, the second standardized difference is obtained in the following manner: obtaining a second air-conditioning parameter corresponding to the actual duty cycle, the second air-conditioning parameter can be understood as the parameter of the air conditioner when the actual duty cycle of the air conditioner is obtained; obtaining the difference between the standard parameter and the second air-conditioning parameter as the third difference, and obtaining the second standardized difference based on the third difference and the correction coefficient, which can be to calculate the product between the third difference and the correction coefficient to obtain the second standardized difference.

[0095] Optionally, the second air-conditioning parameter includes ambient temperature and / or input voltage of the air-conditioning fan, and the first air-conditioning parameter and the second air-conditioning parameter are the same parameter, that is, if the first air-conditioning parameter is ambient temperature, then the second air-conditioning parameter is also ambient temperature, or, if the first air-conditioning parameter is input voltage, then the second air-conditioning parameter is also input voltage, or, if the first air-conditioning parameter is ambient temperature and input voltage, then the second air-conditioning parameter is also ambient temperature and input voltage.

[0096] For example, taking the second air conditioning parameter including the ambient temperature and the input voltage of the air conditioning fan as an example, the second standardized difference includes a second temperature standardized difference and a second voltage standardized difference. Obtain the second ambient temperature of the air conditioner; then obtain the difference between the standard temperature and the second ambient temperature as the fourth difference, and obtain the second temperature standardized difference according to the fourth difference and the temperature correction coefficient. Optionally, the second temperature standardized difference can be the product of the fourth difference and the temperature correction coefficient; obtain the second input voltage of the air conditioning fan; then obtain the difference between the standard voltage and the second input voltage as the fifth difference, and obtain the second voltage standardized difference according to the fifth difference and the voltage correction coefficient. Optionally, the second voltage standardized difference can be the product of the fifth difference and the voltage correction coefficient.

[0097] Combining formula (2) to obtain the following formula (4), the working duty cycle can be obtained by the following formula (4):

[0098] P 1 =P 4 +λ 1 *(T 1 -T 3 )+λ 2*(U 1 -U 3 ) (4)

[0099] Among them, P 1 is the duty cycle, P 4 is the actual duty cycle, T 3 is the second ambient temperature, U 3 is the second input voltage.

[0100] It can be understood that, by performing the above-mentioned standardization processing on the actual duty cycle, it is equivalent to processing the initial duty cycle as the duty cycle under the first air-conditioning parameter (ie, the working duty cycle).

[0101] In this embodiment, the initial duty cycle is subjected to the above-mentioned standardization processing to obtain a preset duty cycle, and the actual duty cycle is subjected to standardization processing to obtain a working duty cycle. Therefore, it can be considered that the preset duty cycle and the working duty cycle are collected under the same conditions, and the degree of dirtiness and blockage obtained based on the two is more accurate.

[0102] Optionally, the degree of dirtiness and blockage obtained after one determination may have errors. In order to improve the accuracy of the determination of the degree of dirtiness and blockage of the air-conditioning filter, the degree of dirtiness and blockage may be obtained multiple times and then the final degree of dirtiness and blockage may be determined. For example, continue to execute steps S110 to S130 until a preset number of identical degrees of dirtiness and blockage are obtained consecutively, and the degree of dirtiness and blockage is determined to be the final degree of dirtiness and blockage.

[0103] Optionally, after obtaining the degree of dirtiness and blockage, the dirtiness and blockage are stored in the memory chip in the order in which they are obtained. If a preset number of identical degrees of dirtiness and blockage are saved continuously, the degree of dirtiness and blockage is determined to be the final degree of dirtiness and blockage. If a new degree of dirtiness and blockage appears during the saving process, for example, the degree of dirtiness and blockage of the air conditioning filter becomes serious and jumps to the next degree of dirtiness and blockage (i.e., the new degree of dirtiness and blockage), or the user cleans the air conditioning filter and obtains a new degree of dirtiness and blockage, then after the new degree of dirtiness and blockage appears continuously for a preset number of times, the new degree of dirtiness and blockage is determined to be the final degree of dirtiness and blockage.

[0104] The preset number may be, but is not limited to, 2, 3, 4, 5, etc.

[0105] As one approach, a detection interval is obtained according to the dirtiness and blockage degree; and then the above steps S110 to S140 are continued according to the obtained detection interval until a preset number of identical dirtiness and blockage degrees are obtained continuously, and the dirtiness and blockage degree is determined as the final dirtiness and blockage degree.

[0106] In the process of obtaining the degree of dirtiness and blockage, if the operating parameters set by the user and the preset working parameters are the same type of parameters, there is a stage of working according to the preset parameters to obtain the working duty cycle. In this case, the operating parameters set by the user may not work. Therefore, in order to ensure the user's experience of the air conditioner, the degree of dirtiness and blockage can be limited to one time per day. Optionally, the degree of dirtiness and blockage of the filter can be detected when the air conditioner is used for the first time on the same day.

[0107] It should be noted that since dust may always exist in the environment where the air conditioner is located, obtaining the final degree of dirtiness and blockage does not mean that steps S110 to S140 will no longer be executed. Steps S110 to S140 can continue to be executed according to the obtained detection interval.

[0108] In this embodiment, by judging the degree of dirtiness and blockage for multiple times, when a preset number of consecutive degrees of dirtiness and blockage are the same, the obtained degree of dirtiness and blockage is reliable, thereby improving the accuracy of the final judgment of the degree of dirtiness and blockage.

[0109] Optionally, a reminder of the degree of dirtiness and blockage of the air conditioner filter can be given, so that the user can clean the dirtiness and blockage in time according to the reminder. For example, a reminder is displayed on the control panel of the air conditioner in the form of text, icons, or voice reminders. Alternatively, a text or voice reminder is given on an electronic device associated with the air conditioner.

[0110] As a method, a reminder may be given for each collected dirtiness and blockage degree, or a reminder may be given for the aforementioned final dirtiness and blockage degree.

[0111] As another method, the degree of dirtiness and blockage collected each time is sequentially stored in the memory chip. When a certain degree of dirtiness and blockage stored is more serious than the next degree of dirtiness and blockage, it means that the user has cleaned the air conditioner filter after the degree of dirtiness and blockage, and the degree of dirtiness and blockage is determined to be the target degree of dirtiness and blockage. The target degree of dirtiness and blockage is then used as the critical value of the air conditioner dirtiness and blockage reminder for the user. That is, when the obtained degree of dirtiness and blockage is the target degree of dirtiness and blockage, the reminder of the degree of dirtiness and blockage begins. Of course, as the dust on the air conditioner filter becomes thicker, the obtained degree of dirtiness and blockage is greater than the target degree of dirtiness and blockage, and the reminder of the degree of dirtiness and blockage will be stopped until the user cleans the filter and the degree of dirtiness and blockage is lower than the target degree of dirtiness and blockage, and the reminder of the degree of dirtiness and blockage stops.

[0112] For example, for a certain air conditioner, the target dirty blockage level is "slight dirty blockage", then, when it is "slight dirty blockage", dirty blockage reminders are started, for example, "slight dirty blockage" is displayed on the air conditioner control panel. If the user does not clean the air conditioner filter, as the dust layer accumulates, the dirty blockage level jumps to "general dirty blockage", then "general dirty blockage" is displayed on the air conditioner control panel. If the user cleans the filter, the obtained dirty blockage level may be "clean", and the dirty blockage level is not displayed on the air conditioner control panel. Since the user has low tolerance for dirty blockage, imagine that for this user, if a reminder is given only when the dirty blockage level is "severe dirty blockage", then there is a situation where the reminder is not timely and the dirty blockage is not cleaned in time. Or, for another user, the tolerance for dirty blockage of the air conditioner filter is stronger. For example, if the target dirty blockage is "severe dirty blockage", then no reminder is given when the dirty blockage level is "clean", "slight dirty blockage" and "general dirty blockage", and when the dirty blockage situation is "severe dirty blockage", "severe dirty blockage" is displayed on the air conditioner control panel. Since the other user is highly tolerant of dirt and blockage, imagine that if a reminder is given when there is "minor dirt and blockage", the user still does not clean up the dirt and blockage, then the reminder will result in a waste of reminder resources or interfere with the user's normal use of the air conditioner.

[0113] In this embodiment, for the air conditioners of users with different usage habits, reminders are given at different levels of dirt and blockage, so that users with different usage habits can clean the dirt and blockage in time.

[0114] Optionally, the present disclosure further provides an electronic device on which a preset application is installed, and when the preset application is executed by a processor, the steps of the aforementioned method are implemented. It can be understood that the preset application is an application for controlling and detecting the degree of dirtiness and blockage of the air conditioning filter.

[0115] The user can remotely control the detection of the degree of dirtiness and blockage of the air conditioning filter through a preset application. For example, after turning on the detection function, the preset application implements the steps of the aforementioned method when executed by the processor. It is understandable that the user enters the setting interface based on the preset application on the electronic device, and turns on the detection function on the setting interface, thereby realizing remote control of the detection of the degree of dirtiness and blockage of the air conditioning filter. Optionally, the user can also turn off the detection function through the setting interface.

[0116] Optionally, the user can also set a shutdown detection based on the preset application, that is, after the air conditioner receives the shutdown command, it will detect the degree of dirtiness of the air conditioner filter and then turn off the air conditioner, thereby achieving the effect of delayed shutdown of the air conditioner.

[0117] The detection interval is an interval set by the user. It is understandable that the user can manually set the detection interval based on the interface of the preset application, for example, the detection interval can be set to 1 day, 2 days, etc.

[0118] The preset application displays a dirty blockage detection pop-up window when the processor executes the above method. It is understandable that when performing dirty blockage detection, the preset application pops up a dirty blockage detection pop-up window to remind the user that the dirty blockage detection is currently being performed, and the dirty blockage degree of the dirty blockage detection can be displayed on the pop-up window. The user can also forcibly turn off the detection function based on the pop-up window.
