[0001] This application relates to the field of air conditioning technology, specifically to a method, device, air conditioner, and storage medium for detecting clogged air conditioning filters. Background Technology

[0002] With the development of air conditioning technology, air conditioning has become increasingly common. Air conditioners include air ducts, and to ensure air quality, filters are installed at the corresponding air outlets or inlets within the ducts. However, these filters can become clogged after prolonged use, affecting the performance of the air conditioner. In related technologies, filter clogging reminders are typically set by pre-setting a usage time. When the preset time is reached, a filter clogging reminder is issued. However, relying on a preset time for clogging reminders cannot accurately reflect the dust accumulation and blockage of the air conditioning filter, resulting in low accuracy.

[0026] Calculate the ratio between the filter usage time and the preset filter usage time, and weight the ratio according to the time weighting coefficient to obtain the first dirt clogging parameter corresponding to the filter usage time;

[0027] The filter clogging parameter is determined by multiplying the first clogging parameter and the airflow compensation parameter.

[0028] In one embodiment of this application, obtaining the filter usage time, air conditioner operating parameters, and inner pipe temperature corresponding to the air conditioner includes:

[0029] In response to the air conditioner's filter clogging detection command, the usage time of the filter is obtained;

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0060] This application provides a method, apparatus, air conditioner, and computer-readable storage medium (hereinafter referred to as storage medium) for detecting air conditioner filter clogging, which will be described in detail below.

[0061] The air conditioner filter clogging detection method in this embodiment of the invention is applied to an air conditioner filter clogging detection device. The air conditioner filter clogging detection device is installed in an air conditioner. The air conditioner is equipped with one or more processors, a memory, and one or more application programs. The one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioner filter clogging detection method. The air conditioner can be a terminal, such as an indoor unit or an outdoor unit. The air conditioner can also be a multi-split air conditioner composed of multiple sub-units (including indoor units and outdoor units).

[0062] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for detecting air conditioner filter clogging according to an embodiment of this application. The scenario for detecting air conditioner filter clogging in this embodiment includes an air conditioner 100 (which integrates an air conditioner filter clogging detection device). The air conditioner 100 runs a computer-readable storage medium corresponding to the air conditioner filter clogging detection to perform the steps of detecting air conditioner filter clogging.

[0063] Understandable Figure 1 The air conditioners in the scenario of the air conditioner filter clogging detection method shown, or the devices contained in the air conditioners, do not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioners in the scenario of the air conditioner filter clogging detection method, or the number or type of devices contained in each air conditioner, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0064] In this embodiment of the invention, the air conditioner 100 is mainly used for: obtaining the filter usage time, air conditioner operating parameters, and inner pipe temperature corresponding to the air conditioner; determining the rated inner pipe temperature corresponding to the air conditioner operating parameters according to a preset mapping table and the air conditioner operating parameters; determining the air volume compensation parameters according to the rated inner pipe temperature and the inner pipe temperature; determining the filter clogging parameters according to the air volume compensation parameters and the filter usage time, and outputting the clogging prompt information corresponding to the clogging parameters.

[0065] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer air conditioners shown, or the air conditioner network connection relationship, for example Figure 1 Only one air conditioner is shown in the diagram. It is understood that the scenario for the air conditioner filter clogging detection method may also include one or more other air conditioners, which are not specifically limited here. The air conditioner 100 may also include a memory for storing data.

[0066] Furthermore, in the scenario of the air conditioner filter clogging detection method of this application, the air conditioner 100 can be equipped with a display device, or the air conditioner 100 can be connected to an external display device 200 without a built-in display device. The display device 200 is used to output the results of the air conditioner filter clogging detection method. The air conditioner 100 can access the background database 300 (the background database can be in the local storage of the air conditioner, or it can be located in the cloud). The background database 300 stores information related to air conditioner filter clogging detection, such as the initial image in the background database 300, or pre-set filtering parameters.

[0067] It should be noted that, Figure 1 The schematic diagram of the air conditioner filter clogging detection method shown is merely an example. The scenario of the air conditioner filter clogging detection method described in this embodiment of the invention is to more clearly illustrate the technical solution of this embodiment of the invention and does not constitute a limitation on the technical solution provided by this embodiment of the invention.

[0068] Based on the scenario described above for detecting dirty air conditioning filters, an embodiment of the method for detecting dirty air conditioning filters is proposed.

[0069] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioning filter clogging detection method in this application. The air conditioning filter clogging detection method includes steps S201-S204:

[0070] S201. Obtain the filter usage time, air conditioner operating parameters, and internal pipe temperature corresponding to the air conditioner.

[0071] The filter usage time, i.e. the cumulative usage time of the filter, can be understood as starting to accumulate time when the air conditioner is working and not accumulating time when the air conditioner is not working.

[0072] It is understandable that the usage time of the filter can be statistically accumulated through timestamps or other methods.

[0073] The air conditioner operating parameters, i.e., the parameters corresponding to the operation of the air conditioner, specifically include the air conditioner's operating mode, compressor frequency, and fan speed; or the air conditioner operating parameters include the air conditioner's operating mode, compressor frequency, and actual speed; or the air conditioner operating parameters include the air conditioner's operating mode, compressor frequency, fan speed, and actual speed. This application does not impose specific limitations on these parameters. The air conditioner operating mode includes preset cooling and heating modes.

[0074] For example, the wind speed can be a wind speed with 1 to N levels, or the wind speed can be a high wind speed, a low wind speed, a medium wind speed, etc. This application does not make specific limitations; it can be understood that the wind speed in the air conditioner operating parameters can be a wind speed value or a wind speed range.

[0075] The inner tube temperature, i.e., the coil temperature of the indoor heat exchanger of the air conditioner, can be understood to be obtained by one or more temperature sensors installed on the inner tube.

[0076] For example, in one embodiment of this application, if the indoor heat exchanger includes multiple temperature sensors, multiple initial inner tube temperatures can be collected for each temperature sensor within a preset time period. The multiple initial inner tube temperatures can be averaged, maximized, or aggregated to obtain the temperature corresponding to each temperature sensor. The temperatures corresponding to multiple temperature sensors can be averaged, maximized, or aggregated to obtain the inner tube temperature.

[0077] For example, in another embodiment of this application, if the indoor heat exchanger includes a temperature sensor, the temperature sensor collects multiple initial inner tube temperatures within a preset time period, and performs average processing, maximum value processing, or aggregation processing on the multiple initial inner tube temperatures to obtain the inner tube temperature.

[0078] Specifically, in the embodiments of this application, the air conditioning filter clogging detection method is applied to an air conditioning filter clogging detection device, which is installed inside the air conditioner. After receiving the air conditioning filter clogging detection command, the air conditioner can obtain the corresponding filter usage time, air conditioner operating parameters, and inner pipe temperature, or the air conditioner can obtain the corresponding filter usage time, air conditioner operating parameters, and inner pipe temperature according to a preset air conditioning filter clogging detection frequency.

[0079] S202. Determine the rated inner pipe temperature corresponding to the air conditioner operating parameters according to the preset mapping table and the air conditioner operating parameters.

[0080] The rated inner tube temperature is the inner tube temperature value corresponding to the air conditioner operating parameters when the air conditioner filter is free of dirt and blockage. For example, the operating parameter is the fan speed. When the fan is running at speed 1, the inner tube temperature value is 35 degrees Celsius.

[0081] It is understood that the preset mapping table includes multiple sets of operating parameters and inner pipe temperatures with mapping relationships, which can be preset for different air conditioners.

[0082] Specifically, after the air conditioner detects the air conditioner operating parameters, it queries a preset mapping table to obtain the inner pipe temperature corresponding to the air conditioner operating parameters as the rated inner pipe temperature.

[0083] S203. Determine the air volume compensation parameters based on the rated inner pipe temperature and the inner pipe temperature.

[0084] The air volume compensation parameter, which is a parameter used to compensate for the air volume of the filter, can be an air volume value, a temperature difference value, or an air volume compensation coefficient, etc.

[0085] It is understandable that when the air conditioner filter becomes clogged, the airflow through the filter decreases, meaning the airflow for heat exchange decreases. This leads to a deviation between the internal pipe temperature and the temperature when the filter is not clogged, and the deviation is directly proportional to the degree of filter clogging. An example is provided: The system detects the rated internal pipe temperature (when the filter is not clogged) corresponding to the current air conditioner operating parameters and determines the airflow compensation parameters based on the rated internal pipe temperature and the actual internal pipe temperature.

[0086] In one embodiment of this application, a preset mapping table (which represents the correspondence between airflow compensation parameters and rated inner pipe temperature and inner pipe temperature) is searched to obtain the airflow compensation parameters corresponding to the rated inner pipe temperature and inner pipe temperature.

[0087] In another embodiment of this application, the temperature difference between the inner tube temperature and the inner tube temperature is calculated, and the temperature difference is determined as the constant air volume compensation parameter.

[0088] S204. Based on the air volume compensation parameters and the filter usage time, determine the filter clogging parameters of the air conditioner, and output the clogging prompt information corresponding to the clogging parameters.

[0089] The filter clogging parameter is a parameter that characterizes the degree of filter clogging. For example, the filter clogging parameter can be a numerical value, and the larger the filter clogging parameter, the more serious the degree of filter clogging.

[0090] Specifically, after determining the airflow compensation parameters based on the rated inner pipe temperature and the inner pipe temperature, the air conditioner can obtain the airflow compensation parameters and the filter clogging parameters corresponding to the filter usage time by looking up a preset table. Alternatively, the airflow compensation parameters and the filter usage time can be input into a preset calculation formula to calculate the filter clogging parameters. It is understood that the preset calculation formula can be obtained through training and fitting. After obtaining the filter clogging parameters, the air conditioner outputs corresponding clogging prompt information based on the clogging parameters. For example, it can output an audible and visual alarm, send a text message, or display it on the air conditioner's display panel.

[0091] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 3 , Figure 3 A flowchart illustrating another embodiment of the air conditioning filter clogging detection method provided in this application includes steps S301-S307:

[0092] S301. Obtain the filter usage time, air conditioner operating parameters, and internal pipe temperature corresponding to the air conditioner.

[0093] S302. Determine the rated inner pipe temperature corresponding to the air conditioner operating parameters according to the preset mapping table and the air conditioner operating parameters.

[0094] S303. Determine the air volume compensation parameters based on the rated inner pipe temperature and the inner pipe temperature.

[0095] The specific implementation methods of steps S301-S303 are shown in any of the above implementation schemes.

[0096] S304. Obtain the ambient temperature of the environment where the air conditioner is located.

[0097] The ambient temperature, i.e. the temperature of the environment in which the indoor heat exchanger of the air conditioner is located, can be understood to be obtained by detecting at least one ambient temperature sensor.

[0098] S305. Correct the ambient temperature according to the preset temperature correction coefficient.

[0099] Specifically, the temperature correction coefficient can be preset based on the historical ambient temperature and historical inner pipe temperature of the air conditioner.

[0100] (1) Under a constant indoor temperature (equivalent to the above stable environment), as the outdoor temperature increases, the cooling capacity gradually decreases, the input power gradually increases, and the energy efficiency ratio gradually decreases. Under a constant outdoor temperature, as the indoor temperature increases, the cooling capacity and input power gradually increase, but the rate of increase in input power is slower than that of cooling capacity, and the energy efficiency ratio generally gradually increases. From this, we can conclude that the cooling capacity has a certain direct proportional relationship with the indoor temperature and a certain inverse proportional relationship with the outdoor temperature.

[0101] (2) Under a constant outdoor temperature, the evaporation temperature increases with increasing indoor temperature, although it may decrease in some areas, but overall it still shows an upward trend. However, at a constant indoor temperature, the effect of changes in outdoor temperature on the evaporation temperature is not significant, i.e.:

[0102] ① Under rated operating conditions (calibrated energy efficiency), the theoretical rated value of evaporation temperature X rated value can be obtained (that is, the rated inner pipe temperature corresponding to the air conditioner's operating parameters).

[0103] ② There is a positive correlation between evaporation temperature and ambient temperature. X (actual evaporator temperature) = X rated + (P2*RT); where P2 is the temperature correction coefficient and RT is the ambient temperature.

[0104] ③ During the air conditioning design process, under normal operating conditions, the temperature of the indoor coil is close to the evaporation temperature, and IPT≈evaporation temperature.

[0105] (3) At the same set temperature, the cooling capacity increases with the increase of the wind speed, and the increase is similar under different indoor temperatures.

[0106] In other words, as described above, a stable indoor environment will have a certain impact on the temperature of the inner pipe. It is understandable that the temperature correction coefficient can be obtained by fitting the formula X(actual evaporator temperature) = X_rated + (P2*RT) based on the actual historical evaporator temperature, air conditioning operating parameters, and the indoor temperature. That is, the temperature correction coefficient is a general value.

[0107] S306. Adjust the air volume compensation parameters according to the corrected ambient temperature.

[0108] As described above, a stable indoor environment will have a certain impact on the temperature of the inner pipe. The ambient temperature is corrected according to the temperature correction coefficient and converted into a temperature compensation value (P2*RT) that affects the temperature of the inner pipe. Then, the air volume compensation parameter is corrected according to the temperature compensation value.

[0109] Specifically, please refer to the formula: △X=(X_fan_bar + (P_inner_ambient_temperature * RT) - IPT)

[0110] Wherein, △X is the air volume compensation parameter adjusted according to the corrected ambient temperature, wherein X fan speed is the rated inner pipe temperature; IPT is the actual inner pipe temperature; and (X fan speed - IPT) is the air volume compensation parameter.

[0111] S307. Based on the filter usage time and the adjusted airflow compensation parameters, determine the filter clogging parameters of the air conditioner, and output the clogging prompt information corresponding to the clogging parameters.

[0112] After adjusting the airflow compensation parameters, the air conditioner determines the filter clogging parameters based on the filter usage time and the adjusted airflow compensation parameters, and outputs the clogging prompt information corresponding to the clogging parameters. This is achieved in the same way as determining the air conditioner filter clogging parameters based on the airflow compensation parameters and the filter usage time, and outputting the clogging prompt information corresponding to the clogging parameters.

[0113] It is understandable that in the technical solution of this application, the filter clogging parameters are determined by combining the ambient temperature, filter usage time and inner pipe temperature, and the original detection device of the air conditioner is used for temperature detection. There is no need to set up additional detection devices for clogging determination, which reduces the cost of clogging detection. At the same time, it takes into account the various factors that affect clogging and ensures the accuracy of clogging detection.

[0114] Furthermore, in another embodiment of this application, the determination of the temperature correction coefficient specifically includes the following steps:

[0115] (1) Match the ambient temperature with a preset temperature range to determine the target temperature range to which the ambient temperature belongs;

[0116] (2) Obtain the preset temperature correction coefficient corresponding to the target temperature range, and perform the step of correcting the ambient temperature according to the preset temperature correction coefficient.

[0117] Specifically, by creating different ambient temperature ranges, different temperature correction coefficients are determined for the influence of the ambient internal temperature on the inner tube temperature in different ambient temperature ranges, so as to ensure the accuracy of the corrected ambient temperature.

[0118] Furthermore, based on the above implementation scheme, this application also provides an implementation scheme for a method for detecting air conditioner filter clogging. In this implementation scheme, the air conditioner operating parameters include fan speed, actual speed, operating mode, and compressor frequency. See [link to relevant documentation]. Figure 4 , Figure 4A flowchart illustrating another embodiment of the air conditioning filter clogging detection method provided in this application includes steps S401-S407:

[0119] S401. Obtain the filter usage time, air conditioner operating parameters, and internal pipe temperature corresponding to the air conditioner.

[0120] The specific implementation method of step S401 is described in any of the above implementation schemes.

[0121] S402. Obtain a preset mapping table corresponding to the working mode and the compressor frequency, wherein the preset mapping table includes a first preset mapping table and a second preset mapping table.

[0122] The first preset mapping table includes multiple sets of gears and temperatures with mapping relationships, and the second preset mapping table includes multiple sets of wind speeds and temperatures with mapping relationships. The actual wind speed is the actual rotation speed of the fan, which can be collected by a preset speed sensor.

[0123] Specifically, after acquiring the air conditioner's operating parameters, the air conditioner determines a corresponding preset mapping table based on the operating mode and compressor frequency in the air conditioner's operating parameters. For example, the frequency range to which the compressor frequency belongs can be determined first, and the corresponding preset mapping table can be determined based on the frequency range and the air conditioner's operating mode. It is understood that the rated inner pipe temperature of the air conditioner in cooling mode and heating mode is different, and the difference in compressor frequency will also affect the inner pipe temperature.

[0124] It is further understood that in some other embodiments of this application, a corresponding preset mapping table can also be determined according to the compressor frequency. That is, the mapping table includes two rated inner pipe temperatures corresponding to the same fan speed or the same fan speed, which respectively correspond to the rated inner pipe temperature of the cooling mode and the rated inner pipe temperature of the heating mode. Furthermore, the rated inner pipe temperature of the heating mode / the rated inner pipe temperature of the cooling mode with the smaller temperature difference between the inner pipe temperatures is selected as the rated inner pipe temperature.

[0125] It is further understood that in some other embodiments of this application, the preset mapping table can also be a general mapping table. A general preset mapping table can be set for the cooling mode and a general preset mapping table can be set for the heating mode; or a general preset mapping table can be set and applied to the corresponding cooling or heating. Similarly, the mapping table includes two rated inner pipe temperatures corresponding to the same fan speed or the same fan speed, which respectively correspond to the rated inner pipe temperature of the cooling mode and the rated inner pipe temperature of the heating mode. Furthermore, the rated inner pipe temperature of the heating mode / the rated inner pipe temperature of the cooling mode with the smaller temperature difference between the inner pipe temperatures is selected as the rated inner pipe temperature.

[0126] It is understood that in some other embodiments of this application, the March meeting mapping table may include only the first preset mapping table or only the second preset mapping table. The specific design can be tailored to actual needs.

[0127] S403. Search the first preset mapping table corresponding to the gear and temperature, and obtain the first inner pipe temperature corresponding to the fan gear.

[0128] The first inner tube temperature is the initial rated inner tube temperature corresponding to the fan speed setting.

[0129] Specifically, in the implementation scheme of this application, the air conditioner operating parameters include the actual speed and fan speed, and the preset mapping table includes a first preset mapping table and a second preset mapping table. After determining the preset mapping table, the air conditioner searches for the first preset mapping table corresponding to the speed and temperature in the preset mapping table to obtain the first inner pipe temperature corresponding to the fan speed.

[0130] S404. Search the second preset mapping table corresponding to wind speed and temperature, and obtain the second inner tube temperature corresponding to the actual rotation speed.

[0131] Wherein, the second inner tube temperature is the initial rated inner tube temperature corresponding to the actual rotational speed;

[0132] Furthermore, the first preset mapping table corresponding to the gear and temperature is searched to obtain the first inner tube temperature corresponding to the fan gear.

[0133] S405. The first inner pipe temperature and the second inner pipe temperature are weighted to obtain the rated inner pipe temperature corresponding to the air conditioner operating parameters.

[0134] It is understood that by inputting the first inner pipe temperature and the second inner pipe temperature into a preset weighted processing formula, the rated inner pipe temperature corresponding to the air conditioner operating parameters is obtained. For example, the first weighted processing formula can be a linear equation in two variables. For example, C in the linear equation in two variables is zero, and the sum of the time weighting coefficient A of the first inner pipe temperature and the time weighting coefficient B of the second inner pipe temperature is 1. It is understood that the specific setting parameters of A and B are not specifically limited in this application.

[0135] It is understandable that the fan speed may fluctuate when operating at a certain fan speed setting, leading to inaccurate fan speed data collection. It is also understandable that, under the same set temperature, the inner tube temperature is higher at higher fan speeds than at lower fan speeds. This application obtains the rated inner tube temperature by combining the fan speed setting with the fan speed, eliminating the deviation caused by collecting only the fan speed setting or only the fan speed data, thus ensuring the accuracy of the rated inner tube temperature.

[0136] Furthermore, during the operation of the air conditioner, the motor fan speed control tends to be stable. The first preset mapping table and the second preset mapping table in the technical solution of this application are used to verify the creation of the inner pipe temperature X (without filter clogging) of different fan speeds under specific verification rated conditions.

[0137] S406. Determine the air volume compensation parameters based on the rated inner pipe temperature and the inner pipe temperature.

[0138] S407. Based on the air volume compensation parameters and the filter usage time, determine the filter clogging parameters of the air conditioner, and output the clogging prompt information corresponding to the clogging parameters.

[0139] The specific implementation methods of steps S406-S407 are shown in any of the above implementation schemes.

[0140] It is understood that in some other embodiments of this application, it may only include a first preset mapping table, that is, the air conditioner operating parameters only include the fan speed. The air conditioner obtains the first inner pipe temperature corresponding to the fan speed by looking up the first preset mapping table corresponding to the speed and temperature, and sets the first inner pipe temperature as the rated inner pipe temperature. In this embodiment, it is not necessary to add an additional fan speed detection sensor, which can reduce the air conditioner setting cost. This application does not make specific limitations.

[0141] It is further understood that, in some implementation schemes, the air conditioner can adjust the air volume compensation parameters by collecting the ambient temperature after obtaining the air volume compensation parameters. For specific implementation methods, please refer to the above implementation schemes.

[0142] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 5 , Figure 5 A flowchart illustrating one embodiment of the air conditioning filter clogging detection method provided in this application for determining filter clogging parameters is shown, including steps S501-S503:

[0143] S501. Obtain the identification information of the filter screen, and obtain a preset time weighting coefficient based on the identification information.

[0144] The identification information of the filter can be filter model, filter number, etc. It is understood that different filter models have different service lives. In the technical solution of this application, different time weighting coefficients are set for different filter models to correct the preset service life of the filter, so that the air conditioner can use different filter models and improve the performance of the air conditioner.

[0145] It is understood that the identification information of the filter can be identified by outputting a filter identification information collection command after the filter is detected to be installed in the air conditioner, or by the user actively scanning the identification information on the filter.

[0146] In some implementations, the air conditioner accesses a preset storage unit to obtain the filter and its stored signal. If the filter is not found, a filter model acquisition command is sent to a mobile terminal connected to the air conditioner, instructing the user to input the filter's identification information or scan the filter's QR code to obtain the filter's identification information. Further, after obtaining the identification information, a weighted coefficient database is searched to obtain the time-weighted coefficient corresponding to the identification information. If the time-weighted coefficient corresponding to the identification information is not found, a time-weighted coefficient acquisition command is sent to obtain the time-weighted coefficient corresponding to the identification information online. For example, the time-weighted coefficient acquisition command is sent to the cloud server corresponding to the air conditioner, where a search for the time-weighted coefficient is performed. If not found, the time-weighted coefficient acquisition command is sent back to the air conditioner's after-sales client via the cloud to obtain the time-weighted coefficient of the identification information from the after-sales client. The identification information is then associated with the time-weighted coefficient and added to the weighted coefficient database.

[0147] S502. Calculate the ratio between the filter usage time and the preset filter usage time, and perform weighting processing on the ratio according to the time weighting coefficient to obtain the first dirt clogging parameter corresponding to the filter usage time.

[0148] For details, please refer to the calculation formula:

[0149]

[0150] Where k is the first clog parameter, and the ratio P is the preset time weighting coefficient.

[0151] S503. Multiply the first dirt clogging parameter and the air volume compensation parameter to determine the filter dirt clogging parameter.

[0152] For details, please refer to the formula:

[0153] Y = k * (X fan speed + (P inner ambient temperature * RT) - IPT);

[0154] Wherein, Y is the filter clogging parameter; P is the internal ambient temperature in the above calculation formula, which is P2.

[0155] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 6 , Figure 6A flowchart illustrating one embodiment of the parameter determination method for detecting clogged air conditioning filters provided in this application includes steps S601-S603:

[0156] S601. Respond to the air conditioner's filter clogging detection command and obtain the filter usage time.

[0157] Specifically, after receiving a filter clogging detection command, the air conditioner accesses the target memory according to a preset duration storage path to obtain the filter usage duration.

[0158] It is understood that the filter clogging detection command can be input by the user through a command input device, such as a voice acquisition device, or obtained by a mobile device, and generated by the air conditioner based on two preset filter clogging detection parameters.

[0159] S602. If the filter usage time exceeds a preset time threshold, then obtain the air conditioner's operating parameters and the initial inner pipe temperature data of the air conditioner in the current working cycle. The initial inner pipe temperature data includes multiple initial inner pipe temperatures.

[0160] Specifically, after obtaining the filter usage time, if the air conditioner detects that the filter usage time is greater than a preset time threshold, it indicates that the filter is likely to be clogged. The air conditioner then obtains the air conditioner's operating parameters and the initial internal pipe temperature data in the current working cycle to determine if the filter is clogged. If the filter usage time is less than or equal to the preset time threshold, it indicates that the filter is less likely to be clogged, and the system directly reports that the filter is not clogged, thus avoiding wasting the clog detection process.

[0161] Furthermore, the initial inner tube temperature data includes multiple initial inner tube temperatures collected by multiple temperature sensors installed at different locations on the inner tube of the indoor heat exchanger.

[0162] S603. Cluster the initial inner tube temperature to obtain the inner tube temperature.

[0163] Specifically, the specific implementation of clustering the initial inner tube temperature to obtain the inner tube temperature is not specifically limited in this application; an example is provided:

[0164] In one embodiment of this application, the mode of the initial inner tube temperature is analyzed and set as the inner tube temperature.

[0165] In another embodiment of this application, the air conditioner processes the initial inner pipe temperature using a preset PCA algorithm model to obtain the inner pipe temperature.

[0166] Furthermore, by analyzing the mode and mean of the initial inner tube temperature values, and based on the range generated by the mode and mean, the mean of the initial inner tube temperature within that range is calculated to obtain the inner tube temperature.

[0167] This implementation scheme improves the efficiency of dirt and blockage detection by receiving data and obtains the inner tube temperature by clustering multiple initial inner tube temperatures, thereby improving the accuracy of inner tube temperature detection and thus improving the accuracy of dirt and blockage detection.

[0168] Furthermore, based on the above implementation scheme, this application also provides a specific implementation method for parameter feedback of dirt and blockage warning information, which specifically includes the following steps:

[0169] (1) If the dirt blockage parameter is greater than the preset dirt blockage threshold, the replacement priority of the air conditioner filter is obtained.

[0170] (2) If the filter replacement priority is greater than the preset priority, a dirt blockage prompt message is sent to the user terminal of the air conditioner;

[0171] (3) If no response is received from the user within the preset time, a voice prompt and / or light prompt will be provided.

[0172] Specifically, after obtaining the dirt / clogging parameters, the air conditioner compares these parameters with a preset dirt / clogging threshold. If the dirt / clogging parameter is greater than the preset threshold, it indicates that the filter is clogged, and the corresponding filter replacement priority is determined. If the filter replacement priority is greater than the preset priority, it indicates that filter replacement is more urgent, and a dirt / clogging alert is sent to the user terminal of the air conditioner. If no response is received from the user within a preset time, a voice prompt and / or light prompt is provided to ensure that the user receives the filter dirt / clogging information in a timely manner and replaces the filter. If the filter replacement priority is not greater than the preset priority, it indicates that filter replacement is not urgent, and only a dirt / clogging alert is sent to the user terminal of the air conditioner so that the user is aware and can replace the filter at their convenience. It is understood that the filter replacement priority can be preset according to the air conditioner's usage environment. For example, if the air conditioner is installed in a food processing workshop, it indicates that the cleanliness requirements of the air conditioner are high, and the filter replacement priority corresponding to the non-urgent filter replacement priority is not set.

[0173] For example, in some other embodiments of this application, if no filter replacement priority is found, image information of the air conditioner installation environment is collected, image recognition processing is performed on the image information to determine the environmental information of the air conditioner, and then the corresponding filter replacement priority is determined based on the environmental information.

[0174] This implementation plan ensures timely filter replacement by pre-setting filter replacement priorities for the corresponding air conditioner operating environment and determining different feedback methods for dirt and clogging alerts based on these priorities. This enhances the performance of the air conditioner.

[0175] This application provides a method for detecting air conditioner filter clogging. It obtains the filter usage time, air conditioner operating parameters, and inner pipe temperature. Based on a preset mapping table and the air conditioner operating parameters, it determines the rated inner pipe temperature corresponding to the operating parameters. Then, based on the rated inner pipe temperature and the inner pipe temperature, it determines the airflow compensation parameter. Finally, based on the airflow compensation parameter and the filter usage time, it determines the air conditioner filter clogging parameter and outputs the clogging warning information corresponding to the clogging parameter. In this solution, the rated inner pipe temperature corresponding to the obtained air conditioner operating parameters is determined. The real-time acquired inner pipe temperature and the rated inner pipe temperature are used to represent the current rated airflow of the fan. The actual airflow is further represented by the inner pipe temperature, and the airflow compensation parameter is determined based on the rated inner pipe temperature and the inner pipe temperature. That is, the clogging information of the air conditioner is determined by combining airflow compensation and filter usage time. While considering the usage time, the impact of filter clogging on the actual airflow is also considered when determining the filter clogging parameter, ensuring the accuracy of the filter clogging judgment.

[0176] To better implement the air conditioning filter clogging detection method in this application embodiment, based on the air conditioning filter clogging detection method, this application embodiment also provides an air conditioning filter clogging detection device, such as...

[0193] The first inner pipe temperature and the second inner pipe temperature are weighted to obtain the rated inner pipe temperature corresponding to the air conditioner operating parameters.

[0194] In one embodiment of this application, the clogging feedback module 704 is used to determine the air conditioner's filter clogging parameters based on the airflow compensation parameters and the filter usage time, and further includes functions for:

[0195] Obtain the identification information of the filter screen, and obtain a preset time weighting coefficient based on the identification information;

[0196] Calculate the ratio between the filter usage time and the preset filter usage time, and weight the ratio according to the time weighting coefficient to obtain the first dirt clogging parameter corresponding to the filter usage time;

[0197] The filter clogging parameter is determined by multiplying the first clogging parameter and the airflow compensation parameter.

[0198] In one embodiment of this application, the acquisition module 701 is used to acquire the filter usage time, air conditioner operating parameters, and inner pipe temperature corresponding to the air conditioner, and further includes a module for:

[0199] In response to the air conditioner's filter clogging detection command, the filter usage time is obtained;

[0200] If the filter usage time exceeds a preset time threshold, the air conditioner's operating parameters and the initial inner pipe temperature data of the air conditioner in the current working cycle are obtained. The initial inner pipe temperature data includes multiple initial inner pipe temperatures.

[0201] The initial inner tube temperature is clustered to obtain the inner tube temperature.

[0202] In one embodiment of this application, the dirt / clogging feedback module 704 is used to provide dirt / clogging warning information based on the dirt / clogging parameters, and further includes functions for:

[0203] If the dirt clogging parameter is greater than the preset dirt clogging threshold, then the replacement priority of the corresponding air conditioner filter is obtained;

[0204] If the filter replacement priority is greater than the preset priority, a dirt / clogging alert message is sent to the user terminal of the air conditioner.

[0205] If no response is received from the user within the preset time, a voice prompt and / or light prompt will be provided.

In this solution, the rated inner pipe temperature corresponding to the obtained air conditioner operating parameters is determined.

The actual air volume is further characterized by the inner pipe temperature, and the air volume compensation parameters are determined based on the rated inner pipe temperature and the inner pipe temperature. That is, the air conditioner's dirt and clogging information is determined by combining air volume compensation and filter usage time. While considering the usage time, the filter dirt and clogging parameters are determined by combining the impact of filter clogging on the actual air volume, ensuring the accuracy of filter dirt and clogging judgment.
