Alternatively, the cooling/heating performance level may represent a temperature decrease value or a temperature increase value of the indoor space per unit volume of the air conditioner per unit operation time period and/or per unit operation power.

The correspondence between the data sets and the refrigeration/heating performance level can be obtained experimentally by a person skilled in the art.

The corresponding relation between the data sets and the refrigerating/heating performance grades can be stored in a one-to-one corresponding data table, and after the first data set is obtained, the first refrigerating/heating performance grade corresponding to the first data set can be obtained by searching the first data set in the one-to-one corresponding data table.

Or, a data fitting mode can be utilized to determine a fitting formula for calculating the data set and the refrigeration/heating performance, and after the first data set is obtained, the first data set is substituted into the fitting formula, so that the first refrigeration/heating performance grade corresponding to the first data set can be obtained.

Alternatively, the correspondence between the data set and the cooling/heating performance level may include: the corresponding relation between the temperature difference, the air conditioner operation time length and the air conditioner operation power and the refrigerating/heating performance grade.

Wherein, the larger the temperature difference value is, the higher the refrigerating/heating performance represented by the refrigerating/heating performance grade is; the shorter the running time of the air conditioner is, the higher the refrigerating/heating performance indicated by the refrigerating/heating performance grade is; the smaller the air conditioner operating power, the higher the cooling/heating performance indicated by the cooling/heating performance level.

In the above embodiment, the room volume/area is ignored in determining the first cooling/heating performance level.

In a specific application process, the volume/area of the room where the air conditioner is located may be regarded as a unit volume/unit area, or 1 cubic meter/square meter may be regarded as a unit volume/unit area, or a numerical value greater than 1 cubic meter/square meter, for example, 5 cubic meters/square meter, 10 cubic meters/square meter, etc., may be regarded as a unit volume/unit area, which will not be described in detail herein.

Fig. 2 and 3 are schematic views of a process for obtaining a confirmation of whether a self-cleaning process is required or not according to an embodiment of the present application.

Referring to fig. 2, according to the first temperature difference, the first cooling/heating performance level, and the preset cooling/heating performance level, a confirmation result of whether to enter the self-cleaning process is obtained, including:

s201, adjusting the first heating/cooling performance level according to the first temperature difference value.

The adjusted first cooling/heating performance level indicates a higher cooling/heating performance than the cooling/heating performance level indicated by the first cooling/heating performance level before adjustment.

For example, the cooling/heating performance level may represent a lower cooling/heating performance as the air conditioner operation duration and/or the air conditioner operation power is greater in the case of decreasing/increasing the temperature of the indoor space per unit volume by the unit temperature; the smaller the air conditioner operation duration and/or the air conditioner operation power, the higher the cooling/heating performance. The adjusted first air conditioner operation time length corresponding to the first refrigeration/heating performance level is smaller than the first air conditioner operation time length corresponding to the original first refrigeration/heating performance level; the adjusted first air conditioner operation power corresponding to the first refrigeration/heating performance level is smaller than the first air conditioner operation power corresponding to the original first refrigeration/heating performance level.

Alternatively, the cooling/heating performance level may represent that the greater the temperature decrease value or the temperature increase value, the higher the cooling/heating performance of the air conditioner in the case of decreasing the temperature or increasing the temperature of the indoor space of a unit volume for a unit operation duration and/or a unit operation power; the smaller the temperature decrease value or the temperature increase value, the lower the cooling/heating performance. The temperature reduction value corresponding to the adjusted first refrigeration/heating performance level is larger than the temperature reduction value corresponding to the original first refrigeration/heating performance level; the temperature increase value corresponding to the adjusted first refrigeration/heating performance level is greater than the temperature increase value corresponding to the original first refrigeration/heating performance level.

Optionally, adjusting the first heating/cooling performance level according to the first temperature difference includes:

obtaining a first air conditioner operation duration and/or a first air conditioner operation power required by the first refrigeration/heating performance grade to enable the temperature of the indoor space in unit volume to be reduced by unit temperature/to be increased by unit temperature;

reducing the first air conditioner operation time length and/or the first air conditioner operation power according to the first temperature difference value; the first air-conditioning operation duration and/or the reduced value of the first air-conditioning operation power are positively correlated with the first temperature difference.

In the process of classifying the refrigerating/heating performance grades, the larger the numerical value of the refrigerating/heating performance grade is, the higher the refrigerating/heating performance is, and the smaller the numerical value of the refrigerating/heating performance grade is, the lower the refrigerating/heating performance is; alternatively, the smaller the value of the cooling/heating performance level is, the lower the cooling/heating formation is, and the larger the value of the cooling/heating performance level is, the higher the cooling/heating performance is.

The more the number of the cooling/heating performance grades is divided, the larger the difference of the required air conditioner operation time length and/or the difference of the air conditioner operation power is, the unit temperature of the indoor space of the unit volume is reduced/the unit temperature is increased corresponding to the adjacent cooling/heating performance grades; the smaller the number of the cooling/heating performance grades is, the smaller the difference in required air conditioner operation time length and/or the difference in air conditioner operation power is. Those skilled in the art can set a proper number of cooling/heating performance levels according to actual needs.

The cooling/heating performance level and the required air conditioner operation duration and/or air conditioner operation power for reducing the temperature of the indoor space in a unit volume by the unit temperature/increasing the unit temperature can be stored in a database, and after the first cooling/heating performance level is obtained, the first air conditioner operation duration and/or the first air conditioner operation power can be obtained by querying the database.

obtaining a first temperature reduction value or a first temperature increase value of an indoor space of a unit volume under unit operation time length and/or unit operation power of an air conditioner corresponding to a first refrigeration/heating performance grade;

increasing the first temperature decrease value or the first temperature increase value according to the first temperature difference value; the first temperature decrease value or the increase value of the first temperature increase value is positively correlated with the first temperature difference value.

The more the number of the cooling/heating performance grades is, the larger the difference value of the temperature reduction value or the temperature increase value of the indoor space in unit volume is caused under the unit operation time length and/or the unit operation power of the air conditioner corresponding to the adjacent cooling/heating performance grades; the smaller the number of the cooling and heating performance grades is, the smaller the difference value of the temperature reduction value or the temperature increase value of the indoor space in unit volume is caused under the unit operation time length and/or the unit operation power of the air conditioner corresponding to the adjacent cooling/heating performance grades. Those skilled in the art can set a proper number of cooling/heating performance levels according to actual needs.

The refrigerating/heating performance grade and the temperature reduction value or the temperature improvement value of the indoor space of the unit volume can be stored in a database under the unit operation time length and/or the unit operation power of the air conditioner, and after the first refrigerating/heating performance grade is obtained, the first temperature reduction value or the first temperature improvement value can be obtained by inquiring the database.

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

The larger the first temperature difference value is, the larger the influence of the outdoor temperature on the indoor temperature is; the smaller the first temperature difference, the less the outdoor temperature affects the indoor temperature.

The first difference threshold represents a critical value between the degree of influence of the outdoor temperature on the indoor temperature that can be ignored and cannot be ignored. The smaller first difference threshold may be set in the case where the cooling or heating demand of the air conditioner is strict, and the larger first difference threshold may be set in the case where the cooling or heating Xu Qiongqiong demand of the air conditioner is relaxed. The person skilled in the art can set the first difference threshold according to the actual requirement.

S202, if the refrigerating/heating performance represented by the adjusted first refrigerating/heating performance level is lower than the refrigerating/heating performance represented by the preset refrigerating/heating performance level, a self-cleaning process is required to be carried out as a confirmation result.

In the case that the cooling/heating performance level may represent a unit temperature reduction/increase of the temperature of the indoor space of a unit volume, and the required air-conditioning operation duration and/or the air-conditioning operation power are/is greater than the air-conditioning operation duration and/or the air-conditioning operation power corresponding to the preset cooling/heating performance level, 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.

The cooling/heating performance level may indicate that the air conditioner is at a unit operation time length and/or a unit operation power, and if the increased first temperature decrease value or first temperature increase value is smaller than the temperature decrease value or temperature increase value corresponding to the preset cooling/heating performance level, it is determined that the adjusted cooling/heating performance indicated by the first cooling/heating performance level is lower than the cooling/heating performance indicated by the preset cooling/heating performance level.

S203, if the refrigerating/heating performance represented by the adjusted first refrigerating/heating performance level is higher than or equal to the refrigerating/heating performance represented by the preset refrigerating/heating performance level, the self-cleaning process is not required to be performed as a confirmation result.

In the case that the cooling/heating performance level may represent a unit temperature reduction/increase of the temperature of the indoor space of a unit volume, and the required air-conditioning operation duration and/or the air-conditioning operation power is smaller than or equal to the preset air-conditioning operation duration and/or the preset air-conditioning operation power corresponding to the preset cooling/heating performance level, if the reduced first air-conditioning operation duration and/or the first air-conditioning operation power is smaller than or equal to the preset air-conditioning operation duration and/or the preset air-conditioning operation power, 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.

The cooling/heating performance grade may indicate that the air conditioner is at the unit operation time length and/or the unit operation 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 grade, determining that the cooling/heating performance indicated by the adjusted first cooling/heating performance grade is greater than or equal to the cooling/heating performance indicated by the preset cooling/heating performance grade.

Referring to fig. 3, according to the first temperature difference, the first cooling/heating performance level, and the preset cooling/heating performance level, a confirmation result of whether to enter the self-cleaning process is obtained, including:

s301, adjusting the preset refrigeration/heating performance level according to the first temperature difference value.

The adjusted preset cooling/heating performance grade represents cooling/heating performance which is lower than the cooling/heating performance represented by the preset cooling/heating performance grade before adjustment.

Optionally, adjusting the preset cooling/heating performance level according to the first temperature difference value includes:

obtaining a preset air conditioner operation time length and/or preset air conditioner operation power required by reducing/increasing the temperature of an indoor space in a unit volume corresponding to a preset refrigeration/heating performance grade;

Increasing a preset air conditioner operation time length and/or preset air conditioner operation power according to the first temperature difference value; the preset air conditioner operation time length and/or the increased value of the preset air conditioner operation power are positively correlated with the first temperature difference value.

obtaining a preset temperature reduction value or a preset temperature increase value of an indoor space of a unit volume under unit operation time length and/or unit operation power of an air conditioner corresponding to a preset refrigeration/heating performance grade;

reducing a preset temperature reduction value or a preset temperature increase value according to the first temperature difference value; the decrease in the preset temperature decrease or the preset temperature increase is positively correlated to the first temperature difference.

In some application scenarios, when the first temperature difference is greater than or equal to the first difference threshold, the preset refrigeration/heating performance level is adjusted according to the first temperature difference.

S302, if the refrigerating/heating performance represented by the first refrigerating/heating performance level is lower than the refrigerating/heating performance represented by the adjusted preset refrigerating/heating performance level, a self-cleaning process is required to be carried out as a confirmation result.

In the case that the cooling/heating performance level may represent a unit temperature reduction/increase of the temperature of the indoor space of the unit volume, and the required air-conditioning operation duration and/or air-conditioning operation power, if the first air-conditioning operation duration and/or the first air-conditioning operation duration corresponding to the first cooling/heating performance level is greater than the increased preset air-conditioning operation duration and/or preset air-conditioning operation power, 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.

And under the condition that the refrigerating/heating performance grade can represent the unit operation duration and/or the unit operation power of the air conditioner, if the first temperature reduction value or the first temperature increase value corresponding to the first refrigerating/heating performance grade is smaller than the reduced preset air conditioner operation duration and/or the preset air conditioner operation power, determining that the refrigerating/heating performance represented by the adjusted first refrigerating/heating performance grade is lower than the refrigerating/heating performance represented by the preset refrigerating/heating performance grade.

S303, if the refrigerating/heating performance represented by the first refrigerating/heating performance level is higher than or equal to the refrigerating/heating performance represented by the adjusted preset refrigerating/heating performance level, the self-cleaning process is not required to be performed as a confirmation result.

And under the condition that the refrigerating/heating performance level can represent that the temperature of the indoor space in unit volume is reduced by unit temperature/increased by unit temperature and the required air conditioner operation time length and/or air conditioner operation power, if the first air conditioner operation time length and/or the first air conditioner operation time length corresponding to the first refrigerating/heating performance level is smaller than or equal to the increased preset air conditioner operation time length and/or preset air conditioner operation power, determining that the refrigerating/heating performance represented by the adjusted first refrigerating/heating performance level is higher than or equal to the refrigerating/heating performance represented by the preset refrigerating/heating performance level.

The cooling/heating performance level may indicate that the air conditioner is at a unit operation time length and/or a unit operation power, and if the first temperature decrease value or the first temperature increase value corresponding to the first cooling/heating performance level is greater than or equal to the decreased preset temperature decrease value or the preset temperature increase value, it is determined that the cooling/heating performance indicated by the adjusted first cooling/heating performance level is greater than or equal to the cooling/heating performance indicated by the preset cooling/heating performance level.

In some application scenarios, the air conditioner is controlled to enter the self-cleaning process after confirming that the condition for entering the self-cleaning process is satisfied.

The self-cleaning process of the air conditioner is the self-cleaning process of the filter screen, or the self-cleaning process of the heat exchanger, or the self-cleaning process of the filter screen and the heat exchanger.

When the filter screen needs to be cleaned, a self-cleaning process of the filter screen is started, and when the heat exchanger needs to be cleaned, the self-cleaning process of the heat exchanger is started.

The specific manner of the self-cleaning process of the filter screen and the specific manner of the self-cleaning process of the heat exchanger can be set by a person skilled in the art according to experience, and will not be described in detail here.

Further, the confirmation method for self-cleaning of the air conditioner further comprises the following steps: after the self-cleaning process is exited, determining a second refrigeration/heating performance grade of the air conditioner according to the second indoor temperature, the second set temperature and a second air conditioner operation time length and/or a second air conditioner operation power required by the second indoor temperature reaching the second set temperature; and under the condition that the degree of improvement of the self-cleaning process on the refrigerating/heating performance of the air conditioner, which is executed, can be represented by the first refrigerating/heating performance grade and the second refrigerating/heating performance grade and meets the preset degree of improvement, the self-cleaning process is determined to be effective, so that the air conditioner can continue to operate.

For example, the time when the self-cleaning process is exited is a third time, the indoor temperature is a second indoor temperature at this time, and at a fourth time, it is determined that the indoor temperature reaches a second set temperature, and the duration between the third time and the fourth time is the second air conditioner operation duration.

The average operation power of the air conditioner is the second air conditioner operation power at the third time to the fourth time, or the total operation power (total consumption electric energy) of the air conditioner is the second air conditioner operation power at the third time to the fourth time.

Wherein determining 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, which may be empirically set by a person skilled in the art, for example, the temperature threshold may be 1 ℃ or 2 ℃.

The second set temperature may be equal to or different from the first set temperature. The first set temperature and the second set temperature can be set according to actual requirements by a person skilled in the art or a user.

The preset increase degree is used to indicate that the self-cleaning process can increase the cooling/heating performance of the air conditioner, that is, the self-cleaning means adopted is effective with the aim of increasing the cooling/heating performance of the air conditioner.

Determining a first refrigerating/heating performance grade of the air conditioner, wherein the first refrigerating/heating performance is used as a judging condition of a first step of the self-cleaning process of the air conditioner, and the refrigerating/heating performance of the air conditioner can be reduced due to the integral dirt blocking degree of the filter screen or the integral pollution degree of the heat exchanger, so that the first refrigerating/heating performance can represent the integral dirt blocking degree of the filter screen or the integral pollution degree of the heat exchanger to a certain extent; and taking the condition that the filter screen or the heat exchanger does not meet the manual cleaning condition as a second step of judging condition, wherein the second step of judging condition can indicate that the filter screen has higher overall dirt blocking degree or the heat exchanger has higher overall dirt blocking degree, but the filter screen does not excessively pollute or excessively block dirt and still belongs to the air conditioner self-cleaning capability and can be processed, and under the condition, the self-cleaning process is determined to be started. The air conditioner can enter the self-cleaning process in any mode, such as manual selection and confirmation by a user, so that the air conditioner enters the self-cleaning process, or the air conditioner automatically enters the self-cleaning process.

In the process of exiting the self-cleaning, the refrigerating/heating performance of the air conditioner is determined again: a second cooling/heating performance level. Because numerous factors such as indoor humidity, indoor air flowing condition, outdoor environment temperature, sealing degree of a room, refrigerant amount of an air conditioning system, self performance of a compressor and a fan can influence refrigerating/heating performance, a certain error can exist when the first refrigerating/heating formation level determined in the previous step is used for indicating the integral dirt blocking degree of a filter screen or the integral dirt blocking degree of a heat exchanger.

The first refrigeration/heating performance grade and the second refrigeration/heating performance grade can represent the improvement degree of the self-cleaning process to the refrigeration/heating performance of the air conditioner, meet the preset improvement degree, can represent the integral dirt blocking degree of the filter screen represented by the first refrigeration/heating performance grade or the integral pollution degree of the heat exchanger, and further can determine that the self-cleaning process is effective, and the air conditioner continues to normally operate.

By adopting the mode, the embodiment of the application takes the improvement of the refrigerating/heating performance of the air conditioner as a starting point, and the first refrigerating/heating performance grade relatively accurately reflects the blocking degree of the filter screen on the whole or the pollution degree of the heat exchanger on the whole, so that the air conditioner timely enters a self-cleaning process, and the effect of improving the refrigerating/heating performance of the air conditioner is realized.

In the embodiment of the application, the air conditioner continues to run, which means that the air conditioner continues to execute according to the default control method and continues to execute the confirmation method for self-cleaning of the air conditioner provided by the embodiment of the application.

And determining that the self-cleaning process is invalid in the case that the first cooling/heating performance level and the second cooling/heating performance level cannot represent the degree of improvement of the cooling/heating performance of the air conditioner by the performed self-cleaning process, and the preset degree of improvement is satisfied. The self-cleaning duration in the next self-cleaning process can be increased, or the user is prompted to manually clean or replace the filter screen, or the heat exchanger is manually cleaned.

The determination process of the second cooling/heating performance level is exemplarily described below.

Optionally, determining the second cooling/heating performance level of the air conditioner according to the second indoor temperature, the second set temperature, and the second air conditioner operation duration and/or the second air conditioner operation power required for reaching the second set temperature from the second indoor temperature includes: obtaining a third temperature difference between the second indoor temperature and the second set temperature; taking the third temperature difference value, the second air conditioner operation time length and/or the second air conditioner operation power as a second data set; and determining a second refrigeration/heating performance grade corresponding to the second data set according to the corresponding relation between the data set and the refrigeration/heating performance grade.

The corresponding relation between the data sets and the refrigerating/heating performance grades can be stored in a one-to-one correspondence data table, and after the second data set is obtained, the second refrigerating/heating performance grade corresponding to the second data set can be obtained by searching the second data set in the one-to-one correspondence data table.

Or, a data fitting mode can be utilized to determine a fitting formula for calculating the data set and the refrigerating/heating performance, and after the second data set is obtained, the second data set is substituted into the fitting formula, so that a second refrigerating/heating performance grade corresponding to the second data set can be obtained.

Optionally, the correspondence between the data set and the refrigeration/heating performance level includes: the corresponding relation between the temperature difference value and the running time of the air conditioner and the grade of the refrigerating/heating performance;

Alternatively, the correspondence between the data set and the cooling/heating performance level may include: setting the corresponding relation between the temperature, the temperature difference value and the air conditioner operation power and the refrigerating/heating performance grade;

In the above embodiment, the room volume/area is ignored in determining the second cooling/heating performance level.

The following exemplarily illustrates the degree of improvement of the self-cleaning process on the refrigerating/heating performance of the air conditioner, which satisfies the preset degree of improvement.

Optionally, the first cooling/heating performance level and the second cooling/heating performance level can represent an improvement degree of the started self-cleaning process on cooling/heating performance of the air conditioner, and the preset improvement degree is satisfied, including: obtaining a first grade difference between the first refrigeration/heating performance grade and the second refrigeration/heating performance grade; determining that the preset improvement degree is met under the condition that the first level difference value is larger than or equal to the second difference value threshold value; wherein the greater the number of divisions of the performance level, the greater the second difference threshold.

Or, the first cooling/heating performance level and the second cooling/heating performance level can represent an improvement degree of the started self-cleaning process on cooling/heating performance of the air conditioner, and the preset improvement degree is satisfied, which may include: under the condition that the air conditioner operation time length and/or the air conditioner operation power are standard operation time length and/or standard operation power, a fourth temperature difference value corresponding to the first refrigeration/heating performance grade and a fifth temperature difference value corresponding to the second refrigeration/heating performance grade are obtained; and determining that the preset improvement degree is met in the case that the difference value between the fourth temperature difference value and the fifth temperature difference value is greater than or equal to the third difference value threshold value.

The fourth temperature difference and the fifth temperature difference may both be temperature decrease values; alternatively, the fourth temperature difference and the fifth temperature difference may both be temperature increase values.

In the above embodiment, the standard operation duration is a preset value, for example, the standard operation duration may be 20min, 30min, or 40min; or the standard operation time length is an average value of time length required by the indoor temperature to reach the set temperature after the current user starts the machine for a plurality of times; or, the standard operation duration may be an average value of durations required for the indoor temperature to reach the set temperature after the air conditioner is started in the process that a plurality of different users use the air conditioner with the same model. The skilled person can determine the appropriate standard operating time according to the actual situation.

In the above embodiment, the standard operation power is a preset value, for example, the standard operation power may be a rated operation power of the air conditioner; or the standard running power is the average running power of the air conditioner in the process that the indoor temperature reaches the set temperature after the current user starts the machine for a plurality of times; or, the standard operation power may be average operation power of the air conditioner in the process that the indoor temperature reaches the set temperature after the air conditioner is started in the process that a plurality of different users use the air conditioner with the same model. One skilled in the art can determine the appropriate standard operating power based on the actual situation.

Or, the first cooling/heating performance level and the second cooling/heating performance level can represent an improvement degree of the started self-cleaning process on cooling/heating performance of the air conditioner, and the preset improvement degree is satisfied, which may include: under the condition that the temperature difference is the standard temperature difference, obtaining a third air conditioner operation duration and/or third air conditioner operation power corresponding to the first refrigeration/heating performance level, and a fourth air conditioner operation duration and/or fourth air conditioner operation power corresponding to the second refrigeration/heating performance level; and determining that the preset improvement degree is met under the condition that the first time length difference value of the third air conditioner operation time length and the fourth air conditioner operation time length is larger than or equal to a first time length threshold value and/or the first power difference value of the third air conditioner operation power and the fourth air conditioner operation power is larger than or equal to a first power threshold value. So as to more accurately determine whether the preset degree of improvement is satisfied.

In the above embodiment, the standard temperature difference is a preset value, for example, the standard temperature difference may be 5 ℃, 10 ℃, or 15 ℃; alternatively, the standard temperature difference may be a temperature difference between the local average temperature and the user average set temperature; alternatively, the standard temperature difference may be a temperature difference between the current seasonal average temperature and the user average set temperature. The skilled person can determine the appropriate standard temperature difference according to the actual situation.

Or, the first cooling/heating performance level and the second cooling/heating performance level can represent an improvement degree of the started self-cleaning process on cooling/heating performance of the air conditioner, and the preset improvement degree is satisfied, which may include: obtaining a fifth air conditioner operation duration and/or fifth air conditioner operation power corresponding to the first refrigeration/heating performance grade and a sixth air conditioner operation duration and/or sixth air conditioner operation power corresponding to the second refrigeration/heating performance grade under the condition that the temperature difference value is a standard temperature difference value and the set temperature is a standard set temperature; and determining that the preset improvement degree is met under the condition that the second time difference value between the fifth air conditioner operation time length and the sixth air conditioner operation time length is larger than or equal to a second time length threshold value and/or the second power difference value between the fifth air conditioner operation power and the sixth air conditioner operation power is larger than or equal to a second power threshold value. So as to more accurately determine whether the preset degree of improvement is satisfied.

In the above embodiment, the standard set temperature may be a human comfort temperature zone, for example, the standard set temperature may be 20 ℃, 21 ℃, 22 ℃, 23 ℃, 24 ℃, 25 ℃, 26 ℃, 27 ℃, 28 ℃; alternatively, the standard set temperature may be normal temperature, such as 25 ℃; alternatively, the standard set temperature may be an average set temperature of the current user; alternatively, the standard set temperature may be an average set temperature of a user using the same model air conditioner. The person skilled in the art can determine the appropriate standard set temperature according to the actual situation.

In some embodiments, the self-cleaning duration of the present self-cleaning process is preset.

For example: the self-cleaning duration of the self-cleaning process is determined according to the difference between the first refrigeration/heating performance level and the preset refrigeration/heating performance level (the preset refrigeration/heating performance level before adjustment or the preset refrigeration/heating performance level after adjustment), and the larger the difference is, the longer the self-cleaning duration is, the smaller the difference is, and the shorter the self-cleaning duration is.

The specific ways of indicating the cooling/heating performance are different, and the ways of determining the self-cleaning time period according to the difference between the first cooling/heating performance level and the preset cooling/heating performance level are also different.

In the case where the cooling/heating performance is directly expressed in terms of the cooling/heating performance level, the self-cleaning period is determined by: obtaining a second grade difference value between the first refrigeration/heating performance grade and a preset refrigeration/heating performance grade; and determining the self-cleaning time length according to the second level difference value, wherein the self-cleaning time length is positively correlated with the second level difference value.

The specific number of the refrigerating/heating performance grades can be set by a person skilled in the art according to actual conditions, and the larger the specific number of the refrigerating/heating performance grades is, the larger the second grade difference value corresponding to the same self-cleaning duration is; the smaller the specific number of cooling/heating performance levels, the smaller the second level difference corresponding to the same self-cleaning duration.

In the case where the cooling/heating performance is expressed in terms of the air-conditioning operation duration and/or the air-conditioning operation power, the self-cleaning duration is determined by:

under the condition that the temperature difference is a standard temperature difference, obtaining a third air conditioner operation duration and/or third air conditioner operation power corresponding to the first refrigeration/heating performance level, and presetting a fourth air conditioner operation duration and/or seventh air conditioner operation power corresponding to the refrigeration/heating performance level; obtaining a third time difference value between the third air conditioner operation time length and the seventh air conditioner operation time length, and/or obtaining a third power difference value between the third air conditioner operation power and the seventh air conditioner operation power; and determining the self-cleaning time according to the third time difference value and/or the third power difference value, wherein the self-cleaning time is positively correlated with the third time difference value and/or the third power difference value.

Or under the condition that the temperature difference value is a standard temperature difference value and the set temperature is a standard set temperature, obtaining fifth air conditioner operation duration and/or fifth air conditioner operation power corresponding to the first refrigeration/heating performance level, and presetting sixth air conditioner operation duration and/or eighth air conditioner operation power corresponding to the refrigeration/heating performance level; obtaining a fourth time length difference value between the fifth air conditioner operation time length and the eighth air conditioner operation time length, and/or obtaining a fourth power difference value between the fifth air conditioner operation power and the eighth air conditioner operation power; and determining the self-cleaning time length according to the fourth time length difference value and/or the fourth power difference value, wherein the self-cleaning time length is positively correlated with the fourth time length difference value and/or the fourth power difference value.

Or under the condition that the air conditioner operation time length and/or the air conditioner operation power are the standard operation time length and/or the standard operation power, obtaining a fourth temperature difference value corresponding to the first refrigeration/heating performance grade and a seventh temperature difference value corresponding to the preset refrigeration/heating performance grade; determining self-cleaning duration according to the difference value of the fourth temperature difference value and the seventh temperature difference value; wherein the difference between the fourth temperature difference and the seventh temperature difference is positively correlated with the self-cleaning duration.

In the multiple execution process of the self-cleaning process, the refrigeration/heating performance represented by the preset refrigeration/heating performance level is continuously reduced along with the increase of the execution times of the self-cleaning process; meanwhile, the air conditioner has a limited self-cleaning capability, resulting in a gradual decrease in the cooling/heating capability indicated by the historical cooling/heating performance level after each self-cleaning process. In general, the increasing speed of the dust amount on the filter screen or the heat exchanger is considered to be substantially unchanged, and along with the repeated execution of the self-cleaning process, the refrigerating/heating performance represented by the preset refrigerating/heating performance level and the refrigerating/heating capacity represented by the historical refrigerating/heating performance level are gradually reduced, so that the difference between the historical refrigerating/heating performance level of the air conditioner after the last self-cleaning and the refrigerating/heating performance represented by the preset refrigerating/heating performance level is relatively fixed, the interval duration between the two self-cleaning processes is relatively fixed, the influence of the self-cleaning process on indoor temperature fluctuation can be further reduced, the temperature stability in the refrigerating/heating process of the air conditioner is improved, and the use experience of a user is improved.
