[0034] Figure 1 This is a schematic diagram of a method for controlling an air conditioner provided in an embodiment of this disclosure; combined with Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0035] S11, when the air conditioner responds to the start-up control command and continues to run for a preset time, the air conditioner obtains the fan speed and the temperature change rate of the area where the target location is located.

[0036] S12, when the air conditioner fan speed is at a preset speed and the temperature change rate of the target location area is at a preset rate, the air conditioner obtains the current input power of the air conditioner compressor.

[0037] S13, the air conditioner determines the degree of dirt and clogging of the air conditioner filter based on the current input power of the air conditioner compressor.

[0038] S14, the air conditioner pushes information about the degree of dirt and clogging to the user so that the user can know the status of the filter in a timely manner.

[0039] In this solution, users can send a start-up control command to the air conditioner. Specifically, users can send the start-up control command by pressing the start-up setting button on the air conditioner's display panel or the remote control associated with the air conditioner. The preset duration can be set based on the air conditioner's stable operating time. As an example, the preset duration can be 10 minutes. The target location is the optimal location within the room where the air conditioner is located that best represents the changes in the indoor ambient temperature. In this way, the air conditioner can obtain the fan speed and the temperature change rate of the target location area while responding to the start-up control command and continuously running for the preset duration. Here, the fan speed can be obtained through the air conditioner's operating information. This method achieves accurate acquisition of the fan speed. Specifically, the air conditioner obtains the temperature change rate of the target location area by: determining the target location; obtaining the amount of temperature change and the duration of temperature change in the target location area; and using the quotient of the amount of temperature change and the duration of temperature change as the temperature change rate of the target location area. This method enables more accurate acquisition of the temperature change rate of the target location area.

[0040] Furthermore, after the air conditioner obtains the fan speed and the temperature change rate of the target location area, the current input power of the air conditioner compressor can be obtained when the air conditioner fan speed is at a preset speed and the temperature change rate of the target location area is at a preset rate. Here, the preset speed is 900 rpm and the temperature change rate is 0.9℃ / min. In this way, the timing for obtaining the current input power of the compressor can be accurately determined, ensuring that the compressor input power obtained in this way matches the degree of filter clogging.

[0041] Understandably, given a fixed fan speed, if the air conditioning filter becomes clogged, the air conditioner compressor's input power will change to maintain its ability to control indoor temperature. Therefore, the degree of clog in the air conditioning filter can be determined by considering the compressor's current input power. This clog level information includes the filter's clogging ratio and / or its clogging grade. As an example, determining the filter's clogging level based on the compressor's current input power involves: accessing a filter database containing clogging ratios for different compressor input powers; matching the clogging ratio corresponding to the current input power in the database; and determining this ratio as the filter's clogging ratio. In another example, determining the filter's clogging level based on the compressor's current input power involves: if the current input power is greater than a first power and less than a second power, determining the filter's clogging grade as fourth; if the current input power is greater than a second power and less than a third power, determining the filter's clogging grade as third. When the current input power is greater than the third power and less than the fourth power, the air conditioner determines the air filter's clogging level to be level two. When the current input power is greater than the fourth power, the air conditioner determines the air filter's clogging level to be level one. This effectively combines the compressor's current input power through multiple methods to accurately determine the degree of clogging of the air filter, improving the accuracy of air filter clogging assessment.

[0042] Furthermore, after determining the degree of dirt and clogging of the air conditioning filter, the air conditioner can push information about this level of dirt and clogging to the user, allowing the user to be promptly informed of the filter's condition. Specifically, the dirt and clogging information can be pushed to the display panel of the user's associated mobile device via text or image; or, after obtaining the user's location information, the information can be pushed to the display panel of the nearest terminal device. This allows the user to be aware of the filter's condition immediately. As an optimized solution, the system can also incorporate the user's identity information to determine their personalized push preferences. For example, if user A's personalized push preference is voice push, the air conditioner can also use a voice module or its associated speaker to display the filter's dirt and clogging status via voice prompts. This solution allows users who are too busy to view text or image information to be aware of the air conditioning filter's condition via voice push.

[0043] The method for controlling an air conditioner provided in this disclosure acquires the fan speed and temperature change rate of the target location area when the air conditioner responds to a start-up control command and runs continuously for a preset time. When the fan speed is at a preset speed and the temperature change rate of the target location area is at a preset rate, the current input power of the air conditioner compressor is acquired. Based on the current input power of the air conditioner compressor, the degree of clogging of the air conditioner filter is determined. This clogging information is then pushed to the user so that the user is aware of the filter's clogging status in a timely manner. This method accurately determines the degree of clogging of the air conditioner filter by combining the current input power of the air conditioner compressor, improving the accuracy of filter clogging assessment. By pushing clogging information to the user, the user is readily aware of the filter's clogging status, eliminating the need for additional filter detection equipment, reducing detection costs, and effectively improving the user experience of the air conditioner.

[0044] Optionally, the information on the degree of dirt and clogging of the air conditioning filter is the dirt and clogging ratio of the air conditioning filter. S13, the air conditioner determines the degree of dirt and clogging of the air conditioning filter based on the current input power of the air conditioning compressor, including:

[0045] The air conditioner obtains a filter information database, which stores the dirt and clogging ratio corresponding to different compressor input powers.

[0046] Match the dirt and clogging ratio corresponding to the current input power in the filter information database and determine it as the dirt and clogging ratio of the air conditioning filter.

[0047] In this solution, the information regarding the degree of dirt and clogging of the air conditioning filter includes the filter's dirt and clogging ratio. Here, the dirt and clogging ratio includes 10%, 20%, 30%, and 40%. Specifically, designers can pre-store a filter information database on the server side based on the filter dirt and clogging test conducted at the factory when the air conditioner leaves the factory. This database stores the dirt and clogging ratios corresponding to different compressor input power levels. As an example, the database stores the following information: a dirt and clogging ratio of 10% for a compressor input power of 1000W; 20% for 1100W; 30% for 1200W; and 40% for 1300W. In this way, the air conditioner can access the filter information database stored on the server side, match it with the dirt and clogging ratio corresponding to the current input power, and determine this as the air conditioning filter's dirt and clogging ratio. For example, if the current input power of the air conditioner is 1200W, a corresponding dirt clogging ratio of 30% can be matched in the filter information database, thus determining that the air conditioner filter has a dirt clogging ratio of 30%. In this way, by combining the current input power, the degree of dirt clogging of the air conditioner filter can be accurately determined, improving the accuracy of air conditioner filter dirt clogging assessment.

[0048] Optionally, the information on the degree of dirtiness of the air conditioning filter is the degree of dirtiness of the air conditioning filter. S13, the air conditioner determines the degree of dirtiness of the air conditioning filter based on the current input power of the air conditioning compressor, including:

[0049] Given that the current input power is greater than the first power but less than the second power, the air conditioner determines the air filter's clogging level to be level four.

[0050] Given that the current input power is greater than the second power but less than the third power, the air conditioner determines the air filter's clogging level to be the third level.

[0051] Given that the current input power is greater than the third power and less than the fourth power, the air conditioner determines the air filter's clogging level to be the second level.

[0052] When the current input power is greater than the fourth power, the air conditioner determines the air filter's clogging level to be the first level.

[0053] In this solution, designers can pre-set power information in the air conditioner to determine the filter clogging level based on the filter clogging test conducted at the factory. This power information includes a first power, a second power, a third power, and a fourth power. For example, the first power is 1000W, the second power is 1100W, the third power is 1200W, and the fourth power is 1300W. Thus, if the current input power is greater than 1000W but less than 1100W, the air conditioner can determine the filter clogging level as fourth; if the current input power is greater than 1100W but less than 1200W, it can determine the filter clogging level as third; if the current input power is greater than 1200W but less than 1300W, it can determine the filter clogging level as second; and if the current input power is greater than 1300W, it can determine the filter clogging level as first. Here, the level of dirt and clogging is ranked as follows: Level 1 > Level 2 > Level 3 > Level 4. This method, combined with the current input power, accurately determines the degree of dirt and clogging in the air conditioning filter, improving the accuracy of filter clogging assessment.

[0054] Optionally, if the current input power of the air conditioner compressor is greater than the fourth power, the air conditioner control will push filter replacement information to the user to remind the user to replace the filter in time.

[0055] In this solution, if the current input power of the air conditioner compressor exceeds the fourth power level, indicating a severe blockage in the air conditioner filter, the system can send a filter replacement notification to the user to remind them to replace the filter promptly. This notification can be in voice, text, or image format. Understandably, to ensure the fastest possible notification, the method of sending the notification is not specifically limited. This approach facilitates timely filter replacement for the user.

[0056] Figure 2 This is a schematic diagram of a method for determining the rate of temperature change provided in an embodiment of this disclosure; combined with Figure 2 As shown, optionally, in step S11, the air conditioner acquires the rate of temperature change in the area where the target location is located, including:

[0057] S21, the air conditioner determines the target location.

[0058] S22, the air conditioner obtains the temperature change and duration of the temperature change in the area where the target location is located.

[0059] S23, the air conditioner uses the ratio of the temperature change amount to the temperature change duration as the temperature change rate of the area where the target location is located.

[0060] In this solution, the air conditioner can determine the target location. Specifically, the air conditioner can obtain information about its installation location and airflow direction, and determine the target location based on this information. This solution ensures that the target location determined in this way better aligns with the air conditioner's airflow pattern.

[0061] Furthermore, after determining the target location, the air conditioner can obtain the temperature change and duration of the temperature change in the area where the target location is located. Specifically, the air conditioner can use its associated infrared sensor to obtain the temperature change in the area where the target location is located. Here, the temperature change in the area where the target location is located refers to the difference between the temperature value of the area where the target location is located at the current moment and the temperature value of the area where the target location is located at the moment the air conditioner is started. The air conditioner can also use its associated timing device to obtain the duration of the temperature change. Here, the duration of the temperature change refers to the difference between the current moment and the moment the air conditioner is started. In this way, accurate acquisition of the temperature change and duration of the temperature change in the area where the target location is located can be achieved.

[0062] Furthermore, after acquiring the amount and duration of temperature change in the target location area, the air conditioner can use the quotient of the temperature change amount and duration as the temperature change rate in the target location area. This method achieves accurate acquisition of the temperature change rate, providing a reliable data basis for determining the condition of the air conditioner filter.

[0063] Optionally, in step S21, the air conditioner determines the target location, including:

[0064] The air conditioner obtains its installation location and the user's current location.

[0065] The air conditioner determines the target location based on its installation location and the user's current location.

[0066] In this solution, the air conditioner can obtain its installation location and the user's current location. The installation location can be the air conditioner's location information, and the user's current location can be determined through the location information of the user's associated mobile device. Furthermore, after obtaining the user's current location, the air conditioner can infer the airflow direction based on the user's current location and their preferred airflow direction. For example, if the user prefers direct airflow, the direction of the air conditioner's airflow relative to the installation location can be determined as the airflow direction. This airflow direction information can include lateral, direct, and other directional information. Thus, after determining the installation location and airflow direction, the air conditioner can accurately determine the target location by combining this with a test distance determined by the air conditioner model. For example, if the test distance determined by the air conditioner model is N, the target location is determined as a distance of N meters from the air conditioner's installation location according to the airflow direction. Here, N is an integer greater than 0. As an example, N can be 1. In this way, the target location can be accurately determined by combining the air conditioner's installation location and the user's current location.

[0067] Figure 3 This is a schematic diagram of a method for obtaining compressor input power provided in an embodiment of this disclosure; combined with Figure 3 As shown, optionally, in step S12, the air conditioner obtains the current input power of the air conditioner compressor, including:

[0068] S31, the air conditioner obtains historical dirt and clogging information of the air conditioner filter. The historical dirt and clogging information includes the degree of dirt and clogging of the air conditioner at different times within a historical period.

[0069] S32, the air conditioner analyzes historical dirt and clogging information to predict when the air conditioner filter will need to be replaced.

[0070] S33, the air conditioning control obtains the current input power of the air conditioning compressor at the target time. The target time is the difference between the predicted time and the pre-check time set by the user.

[0071] In this solution, after each filter clogging test, the air conditioner stores the detected degree of clogging and the corresponding time as historical clogging information on the server. This allows the air conditioner to analyze this historical clogging information to predict when the filter needs replacement. For example, if the historical clogging information includes a 40% clogging rate on January 7th, January 14th, and January 21st, the predicted time for filter replacement (January 28th) can be predicted by analyzing the patterns of these 40% clogging rates. In another example, different times with a clogging level of 1 can be extracted from the historical clogging information and sorted from beginning to end. The rules governing these changes can then be analyzed to predict the time when the air conditioner's filter needs replacement. In this way, the timing of prediction can be accurately determined by combining the dirt and clogging ratio or dirt and clogging level of the air conditioning filter.

[0072] Furthermore, after the air conditioner determines the predicted time, the target time can be determined by combining it with the user-set pre-inspection duration. As an example, the pre-inspection duration can be 5 days. Specifically, the target time is the difference between the predicted time and the user-set pre-inspection duration. For example, if the predicted time is the 28th and the pre-inspection duration is 5 days, then the target time can be calculated as the 23rd. This method enables precise determination of the target time. Thus, after the air conditioner determines the target time, it can be controlled to acquire the current input power of the air conditioner compressor at that target time. This method achieves more accurate acquisition of the air conditioner compressor's input power, avoiding the waste of processing resources caused by the air conditioner frequently acquiring input power.

[0073] Optionally, embodiments of this disclosure provide a method for controlling an air conditioner, comprising:

[0074] When the air conditioner responds to the start-up control command and continues to run for a preset time, the air conditioner obtains the rate of temperature change in the area where the target location is located.

[0075] The air conditioner determines the degree of dirt and clogging of the air filter based on the rate of temperature change in the target location area.

[0076] In this solution, users can send a start-up control command to the air conditioner. Specifically, users can send the start-up control command by pressing the start-up setting button on the air conditioner's display panel or the remote control associated with the air conditioner. The preset duration can be set in conjunction with the air conditioner's stable operating time. As an example, the preset duration can be 10 minutes. The target location is the optimal location within the room where the air conditioner is located that best represents the change in indoor ambient temperature. In this way, the air conditioner can obtain the rate of temperature change in the target location area while responding to the start-up control command and continuously operating for the preset duration. Specifically, obtaining the rate of temperature change in the target location area includes: the air conditioner determining the target location; the air conditioner obtaining the amount of temperature change and the duration of temperature change in the target location area; and the air conditioner using the quotient of the amount of temperature change and the duration of temperature change as the rate of temperature change in the target location area. This method allows for a more accurate acquisition of the rate of temperature change in the target location area while precisely determining the timing of temperature change rate acquisition.

[0077] Understandably, when the air conditioner filter becomes clogged, the air intake of the air conditioner decreases, and the rate at which the air conditioner adjusts the indoor temperature will also slow down accordingly. Therefore, after the air conditioner obtains the temperature change rate of the target location area, it can combine this information with the temperature change rate of the target location area to more accurately determine the degree of cloggering of the air conditioner filter. This cloggering information includes the filter's clogging ratio and / or its clogging level. As an example, the air conditioner determines the degree of cloggering based on the temperature change rate of the target location area by: obtaining a filter information database containing clogging ratios corresponding to different temperature change rates; matching the clogging ratio corresponding to the temperature change rate of the target location area in the filter information database; and determining this as the filter's clogging ratio. In another example, the air conditioner determines the degree of cloggering based on the temperature change rate of the target location area by: if the temperature change rate of the target location area is greater than a first threshold and less than a second threshold, the air conditioner determines the filter's clogging level to be level one. If the rate of temperature change in the target location area is greater than the second threshold but less than the third threshold, the air conditioning system determines the air conditioning filter's clogging level to be level two. If the rate of temperature change in the target location area is greater than the third threshold but less than the fourth threshold, the air conditioning system determines the air conditioning filter's clogging level to be level three. If the rate of temperature change in the target location area is greater than the fourth threshold, the air conditioning system determines the air conditioning filter's clogging level to be level four. This effectively combines multiple methods with the temperature change rate of the target location area to accurately determine the degree of clogging of the air conditioning filter, improving the accuracy of air conditioning filter clogging assessment.

[0078] Optionally, the air conditioner determines the degree of dirt and clogging of the air conditioning filter based on the rate of temperature change in the area where the target location is located, including:

[0079] The air conditioner obtains a filter information database, which stores the dirt and clogging ratio corresponding to different temperature change rates.

[0080] The air conditioner matches the dirt clogging ratio corresponding to the temperature change rate of the target location area in the filter information database and determines it as the dirt clogging ratio of the air conditioner filter.

[0081] In this solution, the information on the degree of dirt and clogging of the air conditioning filter includes the dirt and clogging ratio of the air conditioning filter. Here, the dirt and clogging ratio includes 10%, 20%, 30%, and 40%. Specifically, designers can pre-store a filter information database on the server based on the dirt and clogging test of the filter at the time of air conditioner leaving the factory. The filter information database stores the dirt and clogging ratios corresponding to different temperature change rates. As an example, the information stored in the filter information database includes: a dirt and clogging ratio of 10% for a temperature change rate of 0.9℃ / min; a dirt and clogging ratio of 20% for a temperature change rate of 0.8℃ / min; a dirt and clogging ratio of 30% for a temperature change rate of 0.7℃ / min; and a dirt and clogging ratio of 40% for a temperature change rate of 0.6℃ / min. In this way, the air conditioner can obtain the filter information database stored on the server, match the dirt and clogging ratio in the filter information database with the temperature change rate of the target location area, and determine it as the dirt and clogging ratio of the air conditioning filter. For example, if the temperature change rate of the target location area obtained by the air conditioner is 0.7℃ / min, then a corresponding dirt clogging ratio of 30% can be matched in the filter information database, thus determining that the air conditioner filter has a dirt clogging ratio of 30%. In this way, by combining the temperature change rate of the target location area, the degree of dirt clogging of the air conditioner filter can be accurately determined, improving the accuracy of air conditioner filter dirt clogging assessment.

[0082] Optionally, the information on the degree of dirt and clogging of the air conditioning filter is the degree of dirt and clogging of the air conditioning filter. The air conditioner determines the degree of dirt and clogging of the air conditioning filter based on the rate of temperature change in the area where the target location is located, including:

[0083] If the rate of temperature change in the target location area is greater than the first threshold but less than the second threshold, the air conditioner determines the air conditioner filter to be at level one level of clogging.

[0084] If the rate of temperature change in the target location area is greater than the second threshold but less than the third threshold, the air conditioner determines the air conditioner filter to be at level two in terms of dirt and clogging.

[0085] If the rate of temperature change in the target location area is greater than the third threshold but less than the fourth threshold, the air conditioner determines the air conditioner filter to be at level three in terms of dirt and clogging.

[0086] If the rate of temperature change in the target location area exceeds the fourth threshold, the air conditioner determines the air conditioner filter to be at level four in terms of dirt and clogging.

[0087] In this solution, designers can pre-set threshold information for determining the degree of filter clogging in the air conditioner based on the filter clogging test conducted at the factory. This threshold information includes a first threshold, a second threshold, a third threshold, and a fourth threshold. As an example, the first threshold is 0.6℃ / min, the second threshold is 0.7℃ / min, the third threshold is 0.8℃ / min, and the fourth threshold is 0.9℃ / min. Thus, if the temperature change rate in the target area is greater than 0.6℃ / min and less than 0.7℃ / min, the air conditioner determines the filter clogging level to be first grade; if the temperature change rate in the target area is greater than 0.7℃ / min and less than 0.8℃ / min, the air conditioner determines the filter clogging level to be second grade; if the temperature change rate in the target area is greater than 0.8℃ / min and less than 0.9℃ / min, the air conditioner determines the filter clogging level to be third grade; and if the temperature change rate in the target area is greater than 0.9℃ / min, the air conditioner determines the filter clogging level to be fourth grade. Here, the degree of dirt and clogging is ranked as follows: Level 1 > Level 2 > Level 3 > Level 4. This method, combined with the rate of temperature change in the target area, accurately determines the degree of dirt and clogging of the air conditioning filter, improving the accuracy of air conditioning filter clogging assessment.

[0088] Optionally, if the rate of temperature change in the area where the target location is located does not exceed a first threshold, the air conditioning control will push filter replacement information to the user to remind the user to replace the filter in time.

[0089] In this solution, if the rate of temperature change in the target location area is lower than or equal to a first threshold, and the air conditioner filter is determined to be severely clogged, the air conditioner can send a filter replacement notification to the user to remind them to replace the filter in time. This replacement notification can be in voice, text, or image format. Understandably, to achieve the goal of informing the user to replace the filter as quickly as possible, the specific method of sending the notification is not limited. This approach facilitates timely filter replacement for the user.

[0090] Optionally, the air conditioner determines the target location, including:

[0091] The air conditioner obtains information about its installation location and airflow direction.

[0092] The air conditioner determines the target location based on its installation location and airflow direction.

[0093] In this solution, the air conditioner can obtain its installation location and airflow direction information. Here, the installation location can be the air conditioner's positioning information, and the airflow direction information can include various directions such as lateral and forward, which can be determined by obtaining the air conditioner's operating information. Alternatively, the airflow direction information can be inferred from the user's current location. Furthermore, after obtaining the air conditioner's installation location and airflow direction information, the air conditioner can accurately determine the target location by combining this with the experimental distance determined by the air conditioner model. For example, if the experimental distance determined by the air conditioner model is N, then the target location is determined to be a position N meters away from the air conditioner's installation location according to the airflow direction. Here, N is an integer greater than 0. As an example, N can be 1. In this way, the target location can be accurately determined by combining the air conditioner's installation location and airflow direction information.

[0094] Optionally, the air conditioner acquires the rate of temperature change in the area where the target location is located, including:

[0095] The air conditioner obtains historical information on the dirt and clogging of the air filter, including the degree of dirt and clogging at different times within a historical period.

[0096] The air conditioner analyzes historical information on dirt and clogging to predict when the air conditioner filter will need to be replaced.

[0097] The air conditioning control system obtains the rate of temperature change in the area where the target location is located at a target time. The target time is the difference between the predicted time and the pre-detection time set by the user.

[0098] In this solution, after each filter clogging test, the air conditioner stores the detected degree of clogging and the corresponding time as historical clogging information on the server. This allows the air conditioner to analyze this historical clogging information to predict when the filter needs replacement. For example, if the historical clogging information includes a 40% clogging rate on January 7th, January 14th, and January 21st, the predicted time for filter replacement (January 28th) can be predicted by analyzing the patterns of these 40% clogging rates. In another example, different times with a clogging level of 1 can be extracted from the historical clogging information and sorted from beginning to end. The rules governing these changes can then be analyzed to predict the time when the air conditioner's filter needs replacement. In this way, the timing of prediction can be accurately determined by combining the dirt and clogging ratio or dirt and clogging level of the air conditioning filter.

[0099] Furthermore, after the air conditioner determines the predicted time, the target time can be determined by combining it with the user-set pre-inspection duration. As an example, the pre-inspection duration can be 5 days. Specifically, the target time is the difference between the predicted time and the user-set pre-inspection duration. For example, if the predicted time is the 28th and the pre-inspection duration is 5 days, then the target time can be calculated as the 23rd. This method enables precise determination of the target time. Thus, after the air conditioner determines the target time, it can be controlled to acquire the temperature change rate of the target location area at that time. This method more accurately acquires the temperature change rate of the target location area, avoiding the waste of processing resources caused by the air conditioner frequently acquiring temperature change rate data.

[0100] Optionally, embodiments of this disclosure provide a method for controlling an air conditioner, comprising:

[0101] When the air conditioner responds to the start-up control command and the temperature change in the target area reaches the preset temperature, the air conditioner obtains the humidity status information of the air conditioner's air guide plate.

[0102] The humidity status information on the air conditioner's air guide plate indicates that there are no water droplets on the air guide plate and the air conditioner compressor's input power is at the preset power. The air conditioner then obtains the current speed of the air conditioner fan.

[0103] The air conditioner determines the degree of dirt and clogging of the air filter based on the current speed of the air conditioner fan.

[0104] In this solution, the user can send a start-up control command to the air conditioner. Specifically, the user can send the start-up control command by pressing the start-up setting button on the air conditioner's display panel or the remote control associated with the air conditioner. The target location is the optimal location within the room where the air conditioner is located that best represents the change in indoor ambient temperature. The temperature change in the target location area refers to the difference between the current temperature value of the target location area and the temperature value of the target location area at the time the air conditioner starts. As an example, the preset temperature is 4℃. Thus, when the air conditioner responds to the start-up control command and the temperature change in the target location area reaches 4℃, the humidity status information of the air conditioner's air guide vane can be obtained. Here, the humidity status information can be the humidity value used to determine whether water droplets can form on the air guide vane. Specifically, the humidity status information of the air conditioner's air guide vane can be obtained through a humidity sensor associated with the air conditioner. In this way, accurate acquisition of the humidity status information of the air conditioner's air guide vane is achieved.

[0105] Furthermore, the air conditioner can also determine the presence of water droplets on the air guide vane using an image sensor or a light sensor. As an example, an image sensor can acquire image information of the air guide vane; if water droplet features are extracted from the image, it can be determined that water droplets are present on the air guide vane. In another example, it is understood that the more water droplets on the air guide vane, the greater the scattering of light; therefore, a light sensor can be used to determine the presence of water droplets. This solution allows for multiple methods to determine the presence of water droplets on the air guide vane, accurately determining whether water droplets have formed even if the humidity sensor is damaged or its reading is inaccurate. Furthermore, the air conditioner can obtain the current speed of the air conditioner fan when there are no water droplets on the air guide vane and the air conditioner compressor's input power is at a preset power. As an example, the preset power is 1000W. This solution accurately determines the timing of obtaining the air conditioner fan speed, ensuring the accuracy of the fan speed obtained in this way.

[0106] Understandably, given a fixed input power for the air conditioner compressor, if the air conditioner filter becomes clogged, the air intake volume decreases, and consequently, the air output volume also decreases. This reduces the amount of air flowing over the air guide plate, causing water droplets to accumulate on its surface. To maintain indoor temperature control and accelerate evaporation of the water droplets, the air conditioner fan speed will also change. Therefore, the degree of cloggedness of the air conditioner filter can be determined by combining the current fan speed with the filter's clogging information. This clogging information includes the filter's clogging ratio and / or its clogging level. As an example, determining the filter's clogging level based on the current fan speed involves: the air conditioner accessing a filter information database containing clogging ratios corresponding to different fan speeds; matching the clogging ratio corresponding to the current fan speed in the database; and determining this clogging ratio as the filter's clogging ratio. As an example, the air conditioner determines the degree of dirtiness of the air conditioning filter based on the current fan speed. Specifically: if the current fan speed is higher than a first speed but lower than a second speed, the air conditioner determines the filter dirtiness level to be level four. If the current fan speed is higher than a second speed but lower than a third speed, the air conditioner determines the filter dirtiness level to be level three. If the current fan speed is higher than a third speed but lower than a fourth speed, the air conditioner determines the filter dirtiness level to be level two. If the current fan speed is higher than a fourth speed, the air conditioner determines the filter dirtiness level to be level one. This effectively combines the current fan speed with multiple methods to accurately determine the degree of dirtiness of the air conditioning filter, improving the accuracy of filter dirtiness assessment.

[0107] Optionally, the information on the degree of dirt and clogging of the air conditioning filter is the dirt and clogging ratio of the air conditioning filter. The air conditioner determines the degree of dirt and clogging of the air conditioning filter based on the current speed of the air conditioning fan, including:

[0108] The air conditioner obtains a filter information database, which stores the dirt and clogging ratio corresponding to different fan speeds.

[0109] The air conditioner matches the dirt and clogging ratio corresponding to the current speed in the filter information database and determines it as the dirt and clogging ratio of the air conditioner filter.

[0110] In this solution, the information on the degree of dirt and clogging of the air conditioning filter includes the dirt and clogging ratio of the air conditioning filter. Here, the dirt and clogging ratio includes 10%, 20%, 30%, and 40%. Specifically, designers can pre-store a filter information database on the server side based on the dirt and clogging test of the filter at the time of air conditioner leaving the factory. The filter information database stores the dirt and clogging ratio corresponding to different fan speeds. As an example, the information stored in the filter information database includes: a dirt and clogging ratio of 10% for a fan speed of 1000 rpm; 20% for a fan speed of 1100 rpm; 30% for a fan speed of 1200 rpm; and 40% for a fan speed of 1300 rpm. In this way, the air conditioner can obtain the filter information database stored on the server side, match it with the dirt and clogging ratio corresponding to the current speed in the filter information database, and determine it as the dirt and clogging ratio of the air conditioning filter. For example, if the air conditioner's current speed is 1200 rpm, a corresponding dirt / clogging ratio of 30% can be found in the filter information database, thus determining that the air conditioner filter's dirt / clogging ratio is 30%. This method, by combining the current fan speed, accurately determines the degree of dirt / clogging in the air conditioner filter, improving the accuracy of filter clogging assessment.

[0111] Optionally, the information on the degree of dirt and clogging of the air conditioning filter is the degree of dirt and clogging of the air conditioning filter. The air conditioner determines the degree of dirt and clogging of the air conditioning filter based on the current speed of the air conditioning fan, including:

[0112] If the current speed is greater than the first speed but less than the second speed, the air conditioner determines that the air filter is level four in terms of dirt and clogging.

[0113] If the current speed is greater than the second speed but less than the third speed, the air conditioner determines the air filter's clogging level to be level three.

[0114] If the current speed is greater than the third speed but less than the fourth speed, the air conditioner determines the air filter's clogging level to be level two.

[0115] If the current speed is greater than the fourth speed, the air conditioner determines that the air conditioning filter is at level one level of dirt and clogging.

[0116] In this solution, designers can pre-set speed information in the air conditioner to determine the filter's clogging level based on factory filter clogging tests. This speed information includes a first speed, a second speed, a third speed, and a fourth speed. For example, the first speed is 1000 rpm, the second speed is 1100 rpm, the third speed is 1200 rpm, and the fourth speed is 1300 rpm. Thus, when the current speed is greater than 1000 rpm but less than 1100 rpm, the air conditioner determines the filter's clogging level to be fourth; when the current speed is greater than 1100 rpm but less than 1200 rpm, it determines the filter's clogging level to be third; when the current speed is greater than 1200 rpm but less than 1300 rpm, it determines the filter's clogging level to be second; and when the current input power is greater than 1300W, it determines the filter's clogging level to be first. Here, the degree of clogging in the first level is greater than that in the second level, which is greater than that in the third level, which is greater than that in the fourth level. In this way, the degree of dirt and clogging of the air conditioning filter can be accurately determined by combining the current input power, thus improving the accuracy of the judgment on the dirt and clogging of the air conditioning filter.

[0117] Optionally, if the current air conditioner speed is greater than the fourth speed, the air conditioner control will push filter replacement information to the user to remind the user to replace the filter in time.

[0118] In this solution, if the air conditioner's current speed is higher than the fourth speed setting, indicating a severe blockage in the air filter, the system can send a filter replacement notification to the user to remind them to replace the filter promptly. This notification can be in voice, text, or image format. Understandably, to ensure the fastest possible notification, the method of sending the notification is not specifically limited. This approach facilitates timely filter replacement for the user.

[0119] Optionally, the air conditioner obtains the current speed of the air conditioner fan, including:

[0120] The air conditioner obtains historical information on the dirt and clogging of the air filter, including the degree of dirt and clogging at different times within a historical period.

[0121] The air conditioner analyzes historical information on dirt and clogging to predict when the air conditioner filter will need to be replaced.

[0122] The air conditioning control system obtains the current speed of the air conditioning fan at a target time, which is the difference between the predicted time and the pre-detection time set by the user.

[0123] In this solution, after each filter clogging test, the air conditioner stores the detected degree of clogging and the corresponding time as historical clogging information on the server. This allows the air conditioner to analyze this historical clogging information to predict when the filter needs replacement. For example, if the historical clogging information includes a 40% clogging rate on January 7th, January 14th, and January 21st, the predicted time for filter replacement (January 28th) can be predicted by analyzing the patterns of these 40% clogging rates. In another example, different times with a clogging level of 1 can be extracted from the historical clogging information and sorted from beginning to end. The rules governing these changes can then be analyzed to predict the time when the air conditioner's filter needs replacement. In this way, the timing of prediction can be accurately determined by combining the dirt and clogging ratio or dirt and clogging level of the air conditioning filter.

[0124] Furthermore, after the air conditioner determines the predicted time, the target time can be determined by combining it with the user-set pre-inspection duration. As an example, the pre-inspection duration can be 5 days. Specifically, the target time is the difference between the predicted time and the user-set pre-inspection duration. For example, if the predicted time is the 28th and the pre-inspection duration is 5 days, then the target time can be calculated as the 23rd. This method allows for precise determination of the target time. Thus, after the air conditioner determines the target time, it can be controlled to obtain the current fan speed at that time. This method achieves more accurate acquisition of the air conditioner fan speed, avoiding the waste of processing resources caused by the air conditioner frequently obtaining its fan speed.

This clogging information is then pushed to the user so that the user is aware of the filter's clogging status in a timely manner.

Furthermore, by pushing the clogging information to the user, the user is able to be aware of the filter's clogging status in a timely manner, eliminating the need for additional filter detection equipment, reducing detection costs, and effectively improving the user's experience with the air conditioner.
