Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method, apparatus, and smart air conditioner for verifying self-cleaning of air conditioners. Background Technology

[0002] Currently, air conditioners are equipped with self-cleaning functions. For example, when the filter is found to be more clogged than a preset clog threshold, a self-cleaning process for the filter is initiated; when the heat exchanger is found to be more contaminated than a preset contamination level, a self-cleaning process for the heat exchanger is initiated.

[0003] The self-cleaning function of an air conditioner serves two purposes: firstly, it reduces bacteria growth on the filter or heat exchanger, which helps maintain healthy indoor air; secondly, it improves the ventilation effect of the filter and the heat exchange effect of the heat exchanger, thereby improving the cooling / heating performance of the air conditioner.

[0004] In the process of implementing the embodiments of this application, at least the following problems were found in the related technology:

[0005] Using a high degree of filter clogging or heat exchanger contamination as the entry condition for the air conditioner's self-cleaning process results in a low degree of matching between the timing of the air conditioner entering the self-cleaning process and the need to maintain or improve the air conditioner's cooling / heating performance.

[0017] Optionally, adjusting the first heating / cooling performance level based on the first temperature difference includes: obtaining the first air conditioning operating time and / or the first air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature corresponding to the first cooling / heating performance level; reducing the first air conditioning operating time and / or the first air conditioning operating power based on the first temperature difference; the reduction in the first air conditioning operating time and / or the first air conditioning operating power is positively correlated with the first temperature difference.

[0019] Optionally, adjusting the preset cooling / heating performance level based on the first temperature difference includes: obtaining the preset air conditioning operating time and / or preset air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature corresponding to the preset cooling / heating performance level; increasing the preset air conditioning operating time and / or preset air conditioning operating power based on the first temperature difference; the increase in the preset air conditioning operating time and / or preset air conditioning operating power is positively correlated with the first temperature difference.

[0020] Optionally, adjusting the preset cooling / heating performance level based on the first temperature difference includes: obtaining the preset temperature reduction or preset temperature increase value of the air conditioner corresponding to the preset cooling / heating performance level per unit operating time and / or unit operating power, which causes the indoor space per unit volume to decrease; reducing the preset temperature reduction or preset temperature increase value based on the first temperature difference; the reduction value of the preset temperature reduction or preset temperature increase value is positively correlated with the first temperature difference.

[0021] Optionally, determining the first cooling / heating performance level of the air conditioner based on the first indoor temperature, the first set temperature, and the first air conditioner operating time and / or the first air conditioner operating power required for the indoor temperature to reach the first set temperature includes: obtaining a second temperature difference between the first indoor temperature and the first set temperature; using the second temperature difference, the first air conditioner operating time, and / or the first air conditioner operating power as a first data set, or using the first set temperature, the second temperature difference, the first air conditioner operating time, and / or the first air conditioner operating power as the first data set; and determining the first cooling / heating performance level corresponding to the first data set based on the correspondence between the data set and the cooling / heating performance level.

[0022] Optionally, the correspondence between data sets and cooling / heating performance levels includes: the correspondence between temperature difference and air conditioner operating time and cooling / heating performance levels.

Since there are many factors affecting the cooling / heating performance of an air conditioner, considering the influence of the first temperature difference when determining when the air conditioner enters the self-cleaning process can enhance the connection between the cooling / heating performance of the air conditioner and the self-cleaning process to a certain extent. The confirmation result of whether the self-cleaning process is entered in this way can improve the matching degree between the timing of the air conditioner entering the self-cleaning process and the need to maintain or improve the cooling / heating performance of the air conditioner, thereby promoting the role of the air conditioner self-cleaning process in maintaining or improving the cooling / heating performance of the air conditioner.

[0051] Figure 1This is a flowchart illustrating a method for verifying air conditioner self-cleaning according to an embodiment of this application. This method can be executed in the air conditioner's controller, on a mobile terminal such as a remote control, and in a smart home scenario, it can also be executed on a server.

[0052] Combination Figure 1 As shown, the verification methods for air conditioner self-cleaning include:

[0053] S101. Determine the first cooling / heating performance level of the air conditioner based on the first indoor temperature, the first set temperature, and the first air conditioner operating time and / or the first air conditioner operating power required for the indoor temperature to reach the first set temperature from the first indoor temperature.

[0054] For example, at the first moment, the indoor temperature is the first indoor temperature; at the second moment, the indoor temperature is determined to have reached the first set temperature; the duration between the first moment and the second moment is the first air conditioner running time.

[0055] From the first moment to the second moment, the average operating power of the air conditioner is the first air conditioner operating power, or from the first moment to the second moment, the total operating power (total electrical energy consumption) of the air conditioner is the first air conditioner operating power.

[0056] The determination that the indoor temperature reaches the first set temperature means that the absolute value of the temperature difference between the indoor temperature and the first set temperature is less than or equal to a temperature threshold. Those skilled in the art can set the temperature threshold based on experience. For example, the temperature threshold can be 1°C or 2°C.

[0057] S102, Obtain the first temperature difference between the actual indoor temperature and the outdoor temperature.

[0058] The actual indoor temperature is the first indoor temperature, or the actual indoor temperature is the first set temperature, or the actual indoor temperature is the first average temperature of the first indoor temperature and the first set temperature.

[0059] S103. Based on the first temperature difference, the first cooling / heating performance level, and the preset cooling / heating performance level, obtain a confirmation result on whether to enter the self-cleaning process.

[0060] For example, the first heating / cooling performance level is adjusted based on the first temperature difference; the cooling / heating performance represented by the adjusted first cooling / heating performance level is higher than the cooling / heating performance represented by the first cooling / heating performance level before adjustment.

[0061] Then, based on the cooling / heating performance represented by the adjusted first cooling / heating performance level and the cooling / heating performance represented by the preset cooling / heating performance level, a confirmation result is obtained as to whether the self-cleaning process needs to be entered.

[0062] Alternatively, the preset cooling / heating performance level can be adjusted based on the first temperature difference; the cooling / heating performance represented by the adjusted preset cooling / heating performance level is lower than the cooling / heating performance represented by the original preset cooling / heating performance level.

[0063] Then, based on the cooling / heating performance represented by the first cooling / heating performance level and the cooling / heating performance represented by the adjusted preset cooling / heating performance level, a confirmation result is obtained as to whether the self-cleaning process needs to be entered.

[0064] In this embodiment, the first cooling / heating performance level is determined based on the first indoor temperature, the first set temperature, and the first air conditioner operating time and / or the first air conditioner operating power required for the indoor temperature to reach the first set temperature from the first indoor temperature. Since there are many factors affecting the cooling / heating performance of the air conditioner, considering the influence of the first temperature difference when determining when the air conditioner enters the self-cleaning process can enhance the connection between the cooling / heating performance of the air conditioner and the self-cleaning process to a certain extent. The confirmation result of whether the self-cleaning process is entered in this way can improve the matching degree between the timing of the air conditioner entering the self-cleaning process and the need to maintain or improve the cooling / heating performance of the air conditioner, thereby promoting the maintenance or improvement effect of the air conditioner self-cleaning process on the cooling / heating performance of the air conditioner.

[0065] In this embodiment of the application, if a confirmation result is obtained that the self-cleaning process needs to be entered, it indicates that in order to maintain or improve the cooling / heating performance of the air conditioner, the need for self-cleaning is present. At this time, the user can be reminded and the user can confirm the start of the self-cleaning process, or the air conditioner can automatically start the self-cleaning process.

[0066] The following is an example of how the first cooling / heating performance level is determined:

[0067] Optionally, determining the first cooling / heating performance level of the air conditioner based on the first indoor temperature, the first set temperature, and the first air conditioner operating time and / or the first air conditioner operating power required for the indoor temperature to reach the first set temperature includes: obtaining a second temperature difference between the first indoor temperature and the first set temperature; using the second temperature difference, the first air conditioner operating time, and / or the first air conditioner operating power as a first data set; and determining the first cooling / heating performance level corresponding to the first data set based on the correspondence between the data set and the cooling / heating performance level.

[0068] In the embodiments of this application, the cooling / heating performance rating can represent the air conditioning operating time and / or air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature.

[0069] Alternatively, the cooling / heating performance rating can indicate the temperature reduction or increase per unit volume of indoor space caused by the air conditioner per unit operating time and / or per unit operating power.

[0070] Those skilled in the art can obtain the correspondence between data sets and cooling / heating performance levels through experimentation.

[0071] The correspondence between data sets and cooling / heating performance levels can be stored in a one-to-one correspondence data table. After obtaining the first data set, the first cooling / heating performance level corresponding to the first data set can be obtained by searching for the first data set in the one-to-one correspondence data table.

[0072] Alternatively, a data fitting method can be used to determine the fitting formula for calculating the data set and the cooling / heating performance. After obtaining the first data set, the first data set can be substituted into the fitting formula to obtain the first cooling / heating performance level corresponding to the first data set.

[0073] Optionally, the correspondence between data sets and cooling / heating performance levels includes: the correspondence between temperature difference and air conditioner operating time and cooling / heating performance levels.

[0074] Alternatively, the correspondence between data sets and cooling / heating performance levels can include: the correspondence between temperature difference and air conditioner operating power and cooling / heating performance levels.

[0075] Alternatively, the correspondence between data sets and cooling / heating performance levels can include the correspondence between temperature difference, air conditioner operating time, and air conditioner operating power and cooling / heating performance levels.

[0076] Among them, the greater the temperature difference, the higher the cooling / heating performance indicated by the cooling / heating performance rating; the shorter the air conditioner's operating time, the higher the cooling / heating performance indicated by the cooling / heating performance rating; and the lower the air conditioner's operating power, the higher the cooling / heating performance indicated by the cooling / heating performance rating.

[0077] In the above embodiments, room volume / area was ignored in determining the first cooling / heating performance level.

[0078] In practical applications, the volume / area of ​​the room where the air conditioner is located can be regarded as a unit volume / unit area, or 1 cubic meter / square meter can be regarded as a unit volume / unit area, or values ​​greater than 1 cubic meter / square meter, such as 5 cubic meters / square meter, 10 cubic meters / square meter, etc., can be regarded as a unit volume / unit area. These will not be elaborated on here.

[0079] Optionally, determining the first cooling / heating performance level of the air conditioner based on the first indoor temperature, the first set temperature, and the first air conditioner operating time and / or the first air conditioner operating power required for the indoor temperature to reach the first set temperature includes: obtaining a second temperature difference between the first indoor temperature and the first set temperature; using the first set temperature, the second temperature difference, the first air conditioner operating time, and / or the first air conditioner operating power as a first data set; and determining the first cooling / heating performance level corresponding to the first data set based on the correspondence between the data set and the cooling / heating performance level.

[0080] The correspondence between data sets and cooling / heating performance levels can be stored in a one-to-one correspondence data table. After obtaining the first data set, the first cooling / heating performance level corresponding to the first data set can be obtained by searching for the first data set in the one-to-one correspondence data table.

[0081] Alternatively, a data fitting method can be used to determine the fitting formula for calculating the data set and the cooling / heating performance. After obtaining the first data set, the first data set can be substituted into the fitting formula to obtain the first cooling / heating performance level corresponding to the first data set.

[0082] Optionally, the correspondence between the data set and the cooling / heating performance level may include the correspondence between the set temperature, temperature difference, and air conditioner operating time and the cooling / heating performance level.

[0083] Alternatively, the correspondence between data sets and cooling / heating performance levels may include: the correspondence between set temperature, temperature difference, air conditioner operating power, and cooling / heating performance levels.

[0084] Alternatively, the correspondence between data sets and cooling / heating performance levels may include the correspondence between set temperature, temperature difference, air conditioner running time, and air conditioner operating power and cooling / heating performance levels.

[0085] Among these, the larger the temperature difference, the higher the cooling / heating performance indicated by the cooling / heating performance rating; the shorter the air conditioner's operating time, the higher the cooling / heating performance indicated by the cooling / heating performance rating; the lower the air conditioner's operating power, the higher the cooling / heating performance indicated by the cooling / heating performance rating; during the cooling process, the lower the set temperature, the higher the cooling performance indicated by the cooling / heating performance rating; during the heating process, the higher the set temperature, the higher the cooling performance indicated by the cooling / heating performance rating.

[0086] Figure 2 and Figure 3 This is a schematic diagram of a process for obtaining a confirmation structure to determine whether a self-cleaning process is required, provided in an embodiment of this application.

[0087] Combination Figure 2 As shown, based on the first temperature difference, the first cooling / heating performance level, and the preset cooling / heating performance level, a confirmation result is obtained regarding whether to enter the self-cleaning process, including:

[0088] S201. Adjust the first heating / cooling performance level according to the first temperature difference.

[0089] The adjusted first cooling / heating performance level represents a higher cooling / heating performance than the original first cooling / heating performance level.

[0090] For example, when the cooling / heating performance rating represents the air conditioning operating time and / or operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, a larger air conditioning operating time and / or operating power indicates lower cooling / heating performance; conversely, a smaller air conditioning operating time and / or operating power indicates higher cooling / heating performance. The first air conditioning operating time corresponding to the adjusted first cooling / heating performance rating is less than the first air conditioning operating time corresponding to the original first cooling / heating performance rating; the first air conditioning operating power corresponding to the adjusted first cooling / heating performance rating is less than the first air conditioning operating power corresponding to the original first cooling / heating performance rating.

[0091] Alternatively, where the cooling / heating performance rating represents the temperature decrease or increase per unit volume of indoor space under a unit operating time and / or unit operating power, a larger temperature decrease or increase indicates higher cooling / heating performance; a smaller temperature decrease or increase indicates lower cooling / heating performance. The temperature decrease corresponding to the adjusted first cooling / heating performance rating is greater than the temperature decrease corresponding to the original first cooling / heating performance rating; the temperature increase corresponding to the adjusted first cooling / heating performance rating is greater than the temperature increase corresponding to the original first cooling / heating performance rating.

[0092] Optionally, the first heating / cooling performance level is adjusted based on the first temperature difference, including:

[0093] The first air conditioning operating time and / or first air conditioning operating power required to reduce / increase the temperature of a unit volume of indoor space by a unit temperature, corresponding to the first cooling / heating performance level;

[0094] The operating time and / or power of the first air conditioner are reduced based on the first temperature difference; the reduction in the operating time and / or power of the first air conditioner is positively correlated with the first temperature difference.

[0095] In classifying cooling / heating performance levels, a higher numerical value indicates better cooling / heating performance, while a lower numerical value indicates worse performance; conversely, a lower numerical value indicates worse cooling / heating performance, and a higher numerical value indicates better performance.

[0096] The more cooling / heating performance levels there are, the greater the difference in air conditioning operating time and / or operating power required to lower / raise the temperature per unit volume of indoor space for adjacent cooling / heating performance levels. Conversely, the fewer cooling / heating performance levels there are, the smaller the difference in air conditioning operating time and / or operating power required to lower / raise the temperature per unit volume of indoor space for adjacent cooling / heating performance levels. Those skilled in the art can set an appropriate number of cooling / heating performance levels according to actual needs.

[0097] The cooling / heating performance level, as well as the required air conditioning operating time and / or air conditioning operating power to lower / raise the temperature of a unit volume of indoor space by a unit temperature, can be stored in a database. After obtaining the first cooling / heating performance level, the first air conditioning operating time and / or the first air conditioning operating power can be obtained by querying the database.

[0098] Optionally, the first heating / cooling performance level is adjusted based on the first temperature difference, including:

[0099] To obtain the first temperature reduction or first temperature increase value of a unit volume of indoor space under the unit operating time and / or unit operating power of the air conditioner corresponding to the first cooling / heating performance level;

[0100] The first temperature decrease or increase is increased based on the first temperature difference; the increase in the first temperature decrease or increase is positively correlated with the first temperature difference.

[0101] The more cooling / heating performance levels there are, the greater the difference in temperature decrease or increase per unit volume of indoor space under the same operating time and / or unit operating power for air conditioners of adjacent cooling / heating performance levels. Conversely, the fewer cooling / heating performance levels there are, the smaller the difference in temperature decrease or increase per unit volume of indoor space under the same operating time and / or unit operating power for air conditioners of adjacent cooling / heating performance levels. Those skilled in the art can set an appropriate number of cooling / heating performance levels according to actual needs.

[0102] The cooling / heating performance rating and the temperature reduction or increase value per unit volume of indoor space caused by the air conditioner under unit operating time and / or unit operating power can be stored in a database. After obtaining the first cooling / heating performance rating, the first temperature reduction value or the first temperature increase value can be obtained by querying the database.

[0103] In some application scenarios, if the first temperature difference is greater than or equal to the first difference threshold, the first cooling / heating performance level is adjusted according to the first temperature difference.

[0104] The larger the first temperature difference, the greater the impact of the outdoor temperature on the indoor temperature; the smaller the first temperature difference, the smaller the impact of the outdoor temperature on the indoor temperature.

[0105] The first difference threshold represents the degree to which outdoor temperature affects indoor temperature, a threshold value between negligible and non-negligible influence. When the cooling or heating requirements of the air conditioner are relatively strict, a smaller first difference threshold can be set; conversely, when the cooling or heating requirements are more lenient, a larger first difference threshold can be set. Those skilled in the art can set a suitable first difference threshold based on actual needs.

[0106] S202. If the cooling / heating performance represented by the adjusted first cooling / heating performance level is lower than the cooling / heating performance represented by the preset cooling / heating performance level, then a self-cleaning process will be required as a confirmation result.

[0107] If the cooling / heating performance level can represent the air conditioning operating time and / or air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, and if the reduced first air conditioning operating time and / or first air conditioning operating power is greater than the air conditioning operating time and / or air conditioning operating power corresponding to the preset cooling / heating performance level, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is lower than the cooling / heating performance represented by the preset cooling / heating performance level.

[0108] In the case of a cooling / heating performance level, which can represent the cooling / heating performance of an air conditioner under a unit operating time and / or a unit operating power, if the increased first temperature decrease value or first temperature increase value is less than the temperature decrease value or temperature increase value corresponding to the preset cooling / heating performance level, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is lower than the cooling / heating performance represented by the preset cooling / heating performance level.

[0109] S203. If the cooling / heating performance represented by the adjusted first cooling / heating performance level is higher than or equal to the cooling / heating performance represented by the preset cooling / heating performance level, then there is no need to enter the self-cleaning process as a confirmation result.

[0110] In cases where the cooling / heating performance level can represent the air conditioning operating time and / or air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, if the reduced first air conditioning operating time and / or first air conditioning operating power is less than or equal to the preset air conditioning operating time and / or preset air conditioning operating power corresponding to the preset cooling / heating performance level, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is higher than or equal to the cooling / heating performance represented by the preset cooling / heating performance level.

[0111] In the case where the cooling / heating performance level can represent the air conditioner's cooling / heating performance under unit operating time and / or unit operating power, if the increased first temperature reduction value or first temperature increase value is greater than or equal to the preset temperature reduction value or preset temperature increase value corresponding to the preset cooling / heating performance level, then the cooling / heating performance represented by the adjusted first cooling / heating performance level is determined to be higher than or equal to the cooling / heating performance represented by the preset cooling / heating performance level.

[0112] Combination Figure 3 As shown, based on the first temperature difference, the first cooling / heating performance level, and the preset cooling / heating performance level, a confirmation result is obtained regarding whether to enter the self-cleaning process, including:

[0113] S301. Adjust the preset cooling / heating performance level according to the first temperature difference.

[0114] The cooling / heating performance represented by the adjusted preset cooling / heating performance level is lower than the cooling / heating performance represented by the original preset cooling / heating performance level.

[0115] Optionally, the preset cooling / heating performance level can be adjusted based on the first temperature difference, including:

[0116] To obtain the preset air conditioning operating time and / or preset air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, corresponding to the preset cooling / heating performance level.

[0117] The preset air conditioner running time and / or preset air conditioner operating power are increased based on the first temperature difference; the increase in the preset air conditioner running time and / or preset air conditioner operating power is positively correlated with the first temperature difference.

[0118] Optionally, the preset cooling / heating performance level can be adjusted based on the first temperature difference, including:

[0119] To obtain the preset temperature reduction or preset temperature increase value of a unit volume of indoor space under the unit running time and / or unit operating power corresponding to the preset cooling / heating performance level of the air conditioner;

[0120] The preset temperature decrease or increase value is reduced based on the first temperature difference; the decrease in the preset temperature decrease or increase value is positively correlated with the first temperature difference.

[0121] In some application scenarios, if the first temperature difference is greater than or equal to the first difference threshold, the preset cooling / heating performance level is adjusted according to the first temperature difference.

[0122] S302. If the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the adjusted preset cooling / heating performance level, then a self-cleaning process will be required as a confirmation result.

[0123] When the cooling / heating performance level can represent the air conditioning operating time and / or air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, if the first air conditioning operating time and / or the first air conditioning operating time corresponding to the first cooling / heating performance level is greater than the increased preset air conditioning operating time and / or preset air conditioning operating power, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is lower than the cooling / heating performance represented by the preset cooling / heating performance level.

[0124] In the case where the cooling / heating performance level can represent the air conditioner's cooling / heating performance under unit operating time and / or unit operating power, if the first temperature decrease value or first temperature increase value corresponding to the first cooling / heating performance level is less than the reduced preset air conditioner operating time and / or preset air conditioner operating power, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is lower than the cooling / heating performance represented by the preset cooling / heating performance level.

[0125] S303. If the cooling / heating performance represented by the first cooling / heating performance level is higher than or equal to the cooling / heating performance represented by the adjusted preset cooling / heating performance level, then there is no need to enter the self-cleaning process as a confirmation result.

[0126] When the cooling / heating performance level can represent the air conditioning operating time and / or air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature, if the first air conditioning operating time and / or the first air conditioning operating time corresponding to the first cooling / heating performance level is less than or equal to the increased preset air conditioning operating time and / or preset air conditioning operating power, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is higher than or equal to the cooling / heating performance represented by the preset cooling / heating performance level.

[0127] In the case where the cooling / heating performance level can represent the air conditioner's cooling / heating performance under unit operating time and / or unit operating power, if the first temperature reduction value or the first temperature increase value corresponding to the first cooling / heating performance level is greater than or equal to the reduced preset temperature reduction value or the preset temperature increase value, then it is determined that the cooling / heating performance represented by the adjusted first cooling / heating performance level is higher than or equal to the cooling / heating performance represented by the preset cooling / heating performance level.

[0128] In some application scenarios, once the conditions for entering the self-cleaning process are confirmed, the air conditioner is controlled to enter the self-cleaning process.

[0129] The self-cleaning process of an air conditioner can be the self-cleaning process of the filter, or the self-cleaning process of the heat exchanger, or the self-cleaning process of both the filter and the heat exchanger.

[0130] When the filter needs cleaning, the filter's self-cleaning process is activated; when the heat exchanger needs cleaning, the heat exchanger's self-cleaning process is activated.

[0131] Those skilled in the art can, based on experience, set specific methods for the self-cleaning process of the filter and the heat exchanger, which will not be elaborated here.

[0132] Furthermore, the method for confirming air conditioner self-cleaning also includes: after exiting the current self-cleaning process, determining the second cooling / heating performance level of the air conditioner based on the second indoor temperature, the second set temperature, and the second air conditioner operating time and / or the second air conditioner operating power required to reach the second set temperature from the second indoor temperature; if the first cooling / heating performance level and the second cooling / heating performance level can represent the degree of improvement of the air conditioner's cooling / heating performance by the executed self-cleaning process, and the preset improvement degree is met, determining that the self-cleaning process is effective, and allowing the air conditioner to continue operating.

[0133] For example, the moment when the self-cleaning process ends is the third moment, at which time the indoor temperature is the second indoor temperature. At the fourth moment, it is determined that the indoor temperature has reached the second set temperature. The duration between the third moment and the fourth moment is the second air conditioner running time.

[0134] Between the third and fourth time points, the average operating power of the air conditioner is the second air conditioner operating power, or, between the third and fourth time points, the total operating power (total energy consumption) of the air conditioner is the second air conditioner operating power.

[0135] The determination that the indoor temperature reaches the second set temperature means that the absolute value of the temperature difference between the indoor temperature and the second set temperature is less than or equal to a temperature threshold. Those skilled in the art can set the temperature threshold based on experience. For example, the temperature threshold can be 1°C or 2°C.

[0136] The second set temperature may be equal to or different from the first set temperature. Those skilled in the art or users can set the first and second set temperatures according to actual needs.

[0137] The preset improvement level is used to indicate that the self-cleaning process can improve the cooling / heating performance of the air conditioner. That is, the self-cleaning method adopted is effective in order to improve the cooling / heating performance of the air conditioner.

[0138] The first cooling / heating performance level of the air conditioner is determined and used as the first criterion for the self-cleaning process. Since the overall degree of filter clogging or heat exchanger contamination reduces the air conditioner's cooling / heating performance, this first performance level can, to some extent, indicate the overall degree of filter clogging or heat exchanger contamination. The second criterion is that the filter or heat exchanger does not meet the conditions for manual cleaning. This second criterion indicates that although the overall degree of filter clogging or heat exchanger contamination is high, it is not excessively contaminated or clogged, and is still within the scope of the air conditioner's self-cleaning capability. In this case, it is determined that the self-cleaning process needs to be initiated. The air conditioner can enter the self-cleaning process in any way, such as through user manual selection and confirmation, or automatically.

[0139] During the self-cleaning process, the air conditioner's cooling / heating performance is reassessed: the second cooling / heating performance level. Because numerous factors, such as indoor humidity, indoor airflow, outdoor temperature, room sealing, refrigerant levels in the air conditioning system, and the performance of the compressor and fan, all affect cooling / heating performance, using the first cooling / heating performance level determined in the preceding steps to represent the overall degree of filter or heat exchanger clogging will introduce some error.

[0140] The first and second cooling / heating performance levels can indicate the degree to which the self-cleaning process improves the cooling / heating performance of the air conditioner. If the preset improvement is met, it can accurately indicate the overall degree of clogging of the filter or the overall degree of contamination of the heat exchanger as indicated by the first cooling / heating performance level. Therefore, it can also be determined that the self-cleaning process is effective and the air conditioner continues to operate normally.

[0141] Through the above methods, this application embodiment takes improving the cooling / heating performance of the air conditioner as its starting point. The first cooling / heating performance level more accurately reflects the overall degree of clogging of the filter or the overall degree of contamination of the heat exchanger, so that the air conditioner can enter the self-cleaning process in a timely manner, thereby improving the cooling / heating performance of the air conditioner.

[0142] In this embodiment of the application, "the air conditioner continues to operate" means that the air conditioner continues to execute according to the default control method and continues to execute the confirmation method for air conditioner self-cleaning provided in this embodiment of the application.

[0143] If the first and second cooling / heating performance levels cannot indicate the degree to which the self-cleaning process improves the air conditioner's cooling / heating performance, and the preset improvement level is not met, the self-cleaning process is deemed invalid. The self-cleaning time in the next self-cleaning process can be increased, or the user can be prompted to manually clean or replace the filter, or the heat exchanger can be manually cleaned.

[0144] The following is an exemplary description of the process for determining the second cooling / heating performance level.

[0145] Optionally, a second cooling / heating performance level of the air conditioner is determined based on the second indoor temperature, the second set temperature, and the second air conditioner operating time and / or the second air conditioner operating power required to reach the second set temperature from the second indoor temperature. This includes: obtaining a third temperature difference between the second indoor temperature and the second set temperature; using the third temperature difference, the second air conditioner operating time, and / or the second air conditioner operating power as a second data set; and determining the second cooling / heating performance level corresponding to the second data set based on the correspondence between the data set and the cooling / heating performance level.

[0146] The correspondence between data sets and cooling / heating performance levels can be stored in a one-to-one correspondence data table. After obtaining the second data set, the second cooling / heating performance level corresponding to the second data set can be obtained by searching for the second data set in the one-to-one correspondence data table.

[0147] Alternatively, a data fitting method can be used to determine the fitting formula for calculating the data set and the cooling / heating performance. After obtaining the second data set, the second data set can be substituted into the fitting formula to obtain the second cooling / heating performance level corresponding to the second data set.

[0148] Optionally, the correspondence between the data set and the cooling / heating performance level includes: the correspondence between temperature difference and air conditioner running time and the cooling / heating performance level;

[0149] Alternatively, the correspondence between data sets and cooling / heating performance levels may include: the correspondence between temperature difference and air conditioner operating power and cooling / heating performance levels;

[0150] Alternatively, the correspondence between data sets and cooling / heating performance levels may include: the correspondence between temperature difference, air conditioner running time, and air conditioner operating power and cooling / heating performance levels;

[0151] Alternatively, the correspondence between data sets and cooling / heating performance levels may include: the correspondence between set temperature, temperature difference, air conditioner running time, and cooling / heating performance levels;

[0152] Alternatively, the correspondence between data sets and cooling / heating performance levels may include: the correspondence between set temperature, temperature difference, air conditioner operating power, and cooling / heating performance levels;

[0153] Alternatively, the correspondence between data sets and cooling / heating performance levels may include the correspondence between set temperature, temperature difference, air conditioner running time, and air conditioner operating power and cooling / heating performance levels.

[0154] Among these, the larger the temperature difference, the higher the cooling / heating performance indicated by the cooling / heating performance rating; the shorter the air conditioner's operating time, the higher the cooling / heating performance indicated by the cooling / heating performance rating; the lower the air conditioner's operating power, the higher the cooling / heating performance indicated by the cooling / heating performance rating; during the cooling process, the lower the set temperature, the higher the cooling performance indicated by the cooling / heating performance rating; during the heating process, the higher the set temperature, the higher the cooling performance indicated by the cooling / heating performance rating.

[0155] In the above embodiments, room volume / area was ignored in determining the second cooling / heating performance level.

[0156] In practical applications, the volume / area of ​​the room where the air conditioner is located can be regarded as a unit volume / unit area, or 1 cubic meter / square meter can be regarded as a unit volume / unit area, or values ​​greater than 1 cubic meter / square meter, such as 5 cubic meters / square meter, 10 cubic meters / square meter, etc., can be regarded as a unit volume / unit area. These will not be elaborated on here.

[0157] The following provides an example illustrating the extent to which the self-cleaning process improves the cooling / heating performance of the air conditioner, meeting the preset improvement level.

[0158] Optionally, the first cooling / heating performance level and the second cooling / heating performance level can represent the degree of improvement of the air conditioner's cooling / heating performance by the activated self-cleaning process, and meet the preset improvement degree, including: obtaining a first level difference between the first cooling / heating performance level and the second cooling / heating performance level; and determining that the preset improvement degree is met if the first level difference is greater than or equal to a second difference threshold; wherein, the more performance levels there are, the larger the second difference threshold is.

[0159] In classifying cooling / heating performance levels, a higher numerical value indicates better cooling / heating performance, while a lower numerical value indicates worse performance; conversely, a lower numerical value indicates worse cooling / heating performance, and a higher numerical value indicates better performance.

[0160] Alternatively, the first and second cooling / heating performance levels can represent the degree to which the activated self-cleaning process improves the air conditioner's cooling / heating performance, and satisfying the preset improvement level may include: obtaining a fourth temperature difference value corresponding to the first cooling / heating performance level and a fifth temperature difference value corresponding to the second cooling / heating performance level when the air conditioner's operating time and / or operating power are at the standard operating time and / or standard operating power; and determining that the preset improvement level is satisfied when the difference between the fourth and fifth temperature differences is greater than or equal to a third difference threshold.

[0161] The fourth and fifth temperature differences can both be values ​​that decrease the temperature; or, the fourth and fifth temperature differences can both be values ​​that increase the temperature.

[0162] In the above embodiments, the standard running time is a preset value, such as 20 minutes, 30 minutes, or 40 minutes; or, the standard running time is the average time required for the indoor temperature to reach the set temperature after multiple startups by the current user; or, the standard running time can be the average time required for the indoor temperature to reach the set temperature after the air conditioner is turned on by multiple different users using the same model of air conditioner. Those skilled in the art can determine a suitable standard running time according to the actual situation.

[0163] In the above embodiments, the standard operating power is a preset value, such as the rated operating power of the air conditioner; or, the standard operating power is the average operating power of the air conditioner during the process of the indoor temperature reaching the set temperature after multiple turns on by the current user; or, the standard operating power can be the average operating power of the air conditioner during the process of the indoor temperature reaching the set temperature after the air conditioner is turned on by multiple different users using the same model of air conditioner. Those skilled in the art can determine a suitable standard operating power according to the actual situation.

[0164] Alternatively, the first and second cooling / heating performance levels can represent the degree to which the activated self-cleaning process improves the air conditioner's cooling / heating performance. Meeting a preset improvement level may include: obtaining the third air conditioner operating time and / or the third air conditioner operating power corresponding to the first cooling / heating performance level, and the fourth air conditioner operating time and / or the fourth air conditioner operating power corresponding to the second cooling / heating performance level, provided the temperature difference is a standard temperature difference; and determining that the preset improvement level is met when the first duration difference between the third and fourth air conditioner operating times is greater than or equal to a first duration threshold, and / or the first power difference between the third and fourth air conditioner operating powers is greater than or equal to a first power threshold. This allows for a more accurate determination of whether the preset improvement level is met.

[0165] In the above embodiments, the standard temperature difference is a preset value, for example, the standard temperature difference may be 5℃, 10℃, or 15℃; or, the standard temperature difference may be the temperature difference between the local average temperature and the user's average set temperature; or, the standard temperature difference may be the temperature difference between the current season's average temperature and the user's average set temperature. Those skilled in the art can determine a suitable standard temperature difference based on the actual situation.

[0166] Alternatively, the first and second cooling / heating performance levels can represent the degree to which the activated self-cleaning process improves the air conditioner's cooling / heating performance. Meeting a preset improvement level may include: obtaining the fifth air conditioner operating time and / or fifth air conditioner operating power corresponding to the first cooling / heating performance level, and the sixth air conditioner operating time and / or sixth air conditioner operating power corresponding to the second cooling / heating performance level, provided the temperature difference is a standard temperature difference and the set temperature is a standard set temperature; and determining that the preset improvement level is met when the second time difference between the fifth and sixth air conditioner operating times is greater than or equal to a second time threshold, and / or the second power difference between the fifth and sixth air conditioner operating powers is greater than or equal to a second power threshold. This allows for a more accurate determination of whether the preset improvement level is met.

[0167] In the above embodiments, the standard set temperature can be a range of human comfort temperatures, for example, 20℃, 21℃, 22℃, 23℃, 24℃, 25℃, 26℃, 27℃, or 28℃; or, the standard set temperature can be room temperature, such as 25℃; or, the standard set temperature can be the average set temperature of the current user; or, the standard set temperature can be the average set temperature of users using the same model of air conditioner. Those skilled in the art can determine a suitable standard set temperature based on actual circumstances.

[0168] In some embodiments, the self-cleaning duration of this self-cleaning process is preset.

[0169] For example, the self-cleaning time of this self-cleaning process is determined based on the difference between the first cooling / heating performance level and the preset cooling / heating performance level (the preset cooling / heating performance level before adjustment, or the preset cooling / heating performance level after adjustment). The greater the difference between the two, the longer the self-cleaning time; the smaller the difference between the two, the shorter the self-cleaning time.

[0170] The specific way of representing cooling / heating performance varies, and therefore the method of determining the self-cleaning time based on the difference between the first cooling / heating performance level and the preset cooling / heating performance level also varies.

[0171] When cooling / heating performance is directly represented by a cooling / heating performance level, the self-cleaning time is determined as follows: the difference between the first cooling / heating performance level and the second level of the preset cooling / heating performance level is obtained; the self-cleaning time is determined based on the second level difference, and the self-cleaning time is positively correlated with the second level difference.

[0172] The specific number of cooling / heating performance levels can be set by those skilled in the art according to actual conditions. The more specific numbers of cooling / heating performance levels there are, the greater the difference in the second level corresponding to the same self-cleaning time; the fewer specific numbers of cooling / heating performance levels there are, the smaller the difference in the second level corresponding to the same self-cleaning time.

[0173] When cooling / heating performance is expressed in terms of air conditioner operating time and / or air conditioner operating power, the self-cleaning time is determined as follows:

[0174] Given a standard temperature difference, obtain the third air conditioner operating time and / or the third air conditioner operating power corresponding to the first cooling / heating performance level, and the fourth air conditioner operating time and / or the seventh air conditioner operating power corresponding to the preset cooling / heating performance level; obtain the third duration difference between the third air conditioner operating time and the seventh air conditioner operating time, and / or obtain the third power difference between the third air conditioner operating power and the seventh air conditioner operating power; determine the self-cleaning time based on the third duration difference and / or the third power difference, whereby the self-cleaning time is positively correlated with the third duration difference and / or the third power difference.

[0175] Alternatively, when the temperature difference is the standard temperature difference and the set temperature is the standard set temperature, obtain the fifth air conditioner operating time and / or the fifth air conditioner operating power corresponding to the first cooling / heating performance level, and the sixth air conditioner operating time and / or the eighth air conditioner operating power corresponding to the preset cooling / heating performance level; obtain the fourth duration difference between the fifth air conditioner operating time and the eighth air conditioner operating time, and / or obtain the fourth power difference between the fifth air conditioner operating power and the eighth air conditioner operating power; determine the self-cleaning time based on the fourth duration difference and / or the fourth power difference, wherein the self-cleaning time is positively correlated with the fourth duration difference and / or the fourth power difference.

[0176] Alternatively, when the air conditioner's operating time and / or operating power are at the standard operating time and / or standard operating power, obtain the fourth temperature difference corresponding to the first cooling / heating performance level and the seventh temperature difference corresponding to the preset cooling / heating performance level; determine the self-cleaning time based on the difference between the fourth temperature difference and the seventh temperature difference; wherein the difference between the fourth temperature difference and the seventh temperature difference is positively correlated with the self-cleaning time.

[0177] During multiple self-cleaning cycles, the cooling / heating performance indicated by the preset cooling / heating performance level continuously decreases with each cycle. Simultaneously, the air conditioner's self-cleaning capability is limited, leading to a gradual decrease in the historical cooling / heating capacity indicated by the previous performance level after each cycle. Typically, the rate of dust accumulation on the filter or heat exchanger is considered relatively constant. With repeated self-cleaning, both the preset and historical cooling / heating performance levels gradually decrease, resulting in a relatively fixed difference between the historical and preset performance levels after the last self-cleaning. This, in turn, keeps the interval between two self-cleaning cycles relatively constant. This further reduces the impact of self-cleaning on indoor temperature fluctuations, improves temperature stability during cooling / heating, and enhances the user experience.

This confirmation device for air conditioner self-cleaning can be implemented through software, hardware, or a combination of both.
