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] For filters, the degree of clogging is usually detected by measuring light transmittance; for heat exchangers, the degree of contamination is usually detected by image recognition and reflectivity. Using a high degree of clogging in the filter or a high degree of contamination in the heat exchanger as a condition for initiating the air conditioner's self-cleaning process can easily lead to fluctuations in indoor temperature.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This application provides a method, apparatus, and smart air conditioner for verifying air conditioner self-cleaning, so as to reduce the impact of the self-cleaning process on indoor temperature fluctuations and improve the temperature stability during the air conditioner's cooling / heating process.

[0009] In some embodiments, the method for confirming air conditioner self-cleaning includes: determining a first cooling / heating performance level of the air conditioner based on a first indoor temperature, a first set temperature, and a first air conditioner operating time and / or a first air conditioner operating power required for the indoor temperature to reach the first set temperature from the first indoor temperature; adjusting the first preset cooling / heating performance level in the previous self-cleaning confirmation process to a second preset cooling / heating performance level based on the historical dust amount of the filter or heat exchanger obtained after a historical self-cleaning process; determining that the air conditioner needs to enter a self-cleaning process when the cooling / heating performance represented by the second preset cooling / heating performance level is lower than the cooling / heating performance represented by the first preset cooling / heating performance level; and determining that the air conditioner needs to enter a self-cleaning process when the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level.

[0010] Optionally, based on the historical dust amount of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the confirmation process of the last self-cleaning is adjusted to a second preset cooling / heating performance level. This includes: obtaining the first historical dust amount of the filter or heat exchanger after the last self-cleaning process, and the second historical dust amount of the filter or heat exchanger after the self-cleaning process two years prior; obtaining the first performance level increase value corresponding to the difference between the first historical dust amount and the second historical dust amount based on the correspondence between dust amount and performance level increase value; and determining the second preset cooling / heating performance level based on the sum of the first preset cooling / heating performance level and the first performance level increase value.

[0011] Optionally, based on the historical dust amount of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the confirmation process of the last self-cleaning is adjusted to a second preset cooling / heating performance level, including: obtaining the first historical dust amount of the filter or heat exchanger after the last self-cleaning process; obtaining the second performance level increase value corresponding to the first historical dust amount according to the correspondence between dust amount and performance level increase value; obtaining the original preset cooling / heating performance level corresponding to the first preset cooling / heating performance level; and determining the second preset cooling / heating performance level based on the sum of the original preset cooling / heating performance level and the second performance level increase value.

[0012] 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 first temperature difference between the first indoor temperature and the first set temperature; using the first 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 first 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.

[0013] 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.

[0014] Optionally, the correspondence between data sets and cooling / heating performance levels includes: the correspondence between temperature difference and air conditioner operating power and cooling / heating performance levels.

[0015] Optionally, the correspondence between the data set and the cooling / heating performance level includes: the correspondence between temperature difference, air conditioner running time and air conditioner operating power and the cooling / heating performance level.

[0016] Optionally, the correspondence between data sets and cooling / heating performance levels includes: the correspondence between set temperature, temperature difference, and air conditioner operating time and cooling / heating performance levels.

[0017] Optionally, the correspondence between the data set and the cooling / heating performance level includes: the correspondence between the set temperature, temperature difference, and air conditioner operating power and the cooling / heating performance level.

[0018] Optionally, the correspondence between the data set and the cooling / heating performance level includes: the correspondence between the set temperature, temperature difference, air conditioner running time and air conditioner operating power and the cooling / heating performance level.

[0019] 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.

[0020] Optionally, the self-cleaning time of this self-cleaning process is determined based on the difference between the first cooling / heating performance level and the second preset cooling / heating performance level. 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.

[0021] Optionally, the self-cleaning time is determined by: obtaining the first level difference between the first cooling / heating performance level and the second preset cooling / heating performance level; determining the self-cleaning time based on the first level difference, wherein the self-cleaning time is positively correlated with the first level difference.

[0022] Optionally, the self-cleaning time is determined as follows: Given a standard temperature difference, the operating time and / or power of the second air conditioner corresponding to the first cooling / heating performance level, and the operating time and / or power of the third air conditioner corresponding to the second preset cooling / heating performance level are obtained; a first time difference between the second and third air conditioner operating times is obtained, and / or a first power difference between the second and third air conditioner operating powers is obtained; the self-cleaning time is determined based on the first time difference and / or the first power difference, wherein the self-cleaning time is positively correlated with the first time difference and / or the first power difference.

[0023] Optionally, the self-cleaning time is determined as follows: Given a temperature difference equal to a standard temperature difference and a set temperature equal to a standard set temperature, the fourth air conditioner operating time and / or fourth air conditioner operating power corresponding to the first cooling / heating performance level, and the fourth air conditioner operating time and / or fourth air conditioner operating power corresponding to the second preset cooling / heating performance level are obtained; a second time difference between the fourth and fifth air conditioner operating times is obtained, and / or a second power difference between the fourth and fifth air conditioner operating powers is obtained; the self-cleaning time is determined based on the second time difference and / or the second power difference, wherein the self-cleaning time is positively correlated with the second time difference and / or the second power difference.

[0024] Optionally, when the air conditioner's operating time and / or operating power are at the standard operating time and / or standard operating power, a second temperature difference value corresponding to the first cooling / heating performance level and a third temperature difference value corresponding to the preset cooling / heating performance level are obtained; the self-cleaning time is determined based on the difference between the second temperature difference value and the third temperature difference value; wherein, the difference between the second temperature difference value and the third temperature difference value is positively correlated with the self-cleaning time.

[0025] Optionally, the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, including the following situations: when the cooling / heating performance level represents 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, the first air conditioning operating time represented by the first cooling / heating performance level is greater than the second preset air conditioning operating time represented by the second preset cooling / heating performance level, or the first air conditioning operating power represented by the first cooling / heating performance level is greater than the second preset air conditioning operating power represented by the second preset cooling / heating performance level.

[0026] Optionally, the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, including: when the cooling / heating performance level represents the temperature reduction or increase value of a unit volume of indoor space caused by the air conditioner under unit operating time and / or unit operating power, the first temperature reduction value represented by the first cooling / heating performance level is less than the second preset temperature reduction value represented by the second preset cooling / heating performance level; or, the first temperature increase value represented by the first cooling / heating performance level is less than the second preset temperature increase value represented by the second preset cooling / heating performance level.

[0027] In some embodiments, the confirmation device for air conditioner self-cleaning includes a first determining module, an obtaining module, and a second determining module.

[0028] The first determining module is used to 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.

[0029] The module is used to adjust the first preset cooling / heating performance level of the previous self-cleaning confirmation process to the second preset cooling / heating performance level based on the historical dust amount of the filter or heat exchanger obtained after the historical self-cleaning process; the cooling / heating performance represented by the second preset cooling / heating performance level is lower than the cooling / heating performance represented by the first preset cooling / heating performance level.

[0030] The second determining module is used to determine that the air conditioner needs to enter the self-cleaning process when the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level.

[0031] In some embodiments, the device for verifying air conditioner self-cleaning includes a processor and a memory storing program instructions, the processor being configured to execute the verification method for air conditioner self-cleaning provided in the foregoing embodiments when executing the program instructions.

[0032] In some embodiments, the smart air conditioner includes the verification device for air conditioner self-cleaning provided in the foregoing embodiments.

[0033] The method, apparatus, and smart air conditioner for confirming air conditioner cleaning provided in this application can achieve the following technical effects:

[0034] Since the overall degree of clogging of the filter or the overall contamination of the heat exchanger will reduce the cooling / heating performance of the air conditioner, the first cooling / heating performance can, to some extent, represent the overall degree of clogging of the filter or the overall contamination of the heat exchanger. However, because many factors such as indoor humidity, indoor air circulation, outdoor ambient temperature, room sealing, refrigerant quantity in the air conditioning system, and the performance of the compressor and fan themselves all affect the cooling / heating performance, using the first cooling / heating performance level determined in the aforementioned steps to represent the overall degree of clogging of the filter or the heat exchanger will have a certain degree of error, and this error is not constant but easily changes.

[0035] The second preset cooling / heating performance level is equivalent to a standard indicator used to measure whether the first cooling / heating performance level meets the standard. Failure to meet the first cooling / heating performance level is due to a combination of factors, including the amount of dust on the filter or heat exchanger.

[0036] Based on the historical dust levels of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the previous self-cleaning confirmation process is adjusted to obtain a second preset cooling / heating performance level. This indicates that the second preset cooling / heating performance level used in this self-cleaning process is relative and variable. Furthermore, the cooling / heating performance represented by the second preset cooling / heating performance level is lower than the cooling / heating performance represented by the first preset cooling / heating performance level, indicating that the measurement standard has been lowered in this self-cleaning process.

[0037] Air conditioners have limited self-cleaning capabilities, and a certain amount of dust remains after each cleaning process. When the amount of dust on the filter or heat exchanger increases, the measurement standard for this cleaning process is lowered. For the change in the first cooling / heating performance level caused by factors other than the filter or heat exchanger, the redundant space for compressing the change is not compressed or is reduced. This reduces the phenomenon of the air conditioner frequently entering the self-cleaning process and reduces the impact of the self-cleaning process on indoor temperature fluctuations.

[0038] Through the above methods, this application embodiment reduces the cooling / heating performance slightly in a manner consistent with the self-cleaning capability of the air conditioner, thereby reducing the impact of the self-cleaning process on indoor temperature fluctuations, improving the temperature stability during the air conditioner's cooling / heating process, and enhancing the user experience.

[0047] To provide a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this application. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0048] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0049] Unless otherwise stated, the term "multiple" means two or more.

[0050] In this embodiment, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0051] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0052] When the air conditioner is in cooling mode, the terms "cooling / heating performance" and "cooling / heating performance level" refer to the air conditioner's cooling performance and cooling performance level; when the air conditioner is in heating mode, the terms "cooling / heating performance" and "cooling / heating performance level" refer to the air conditioner's heating performance and heating performance level.

[0053] In this embodiment, taking the maintenance of the air conditioner's cooling / heating performance as the starting point, and considering the limited cleaning effect of the air conditioner's self-cleaning function, the measurement index of the entry conditions for the self-cleaning process is reduced. At the cost of slightly reducing the cooling / heating performance, the impact of the self-cleaning process on indoor temperature fluctuations is reduced, the temperature stability during the air conditioner's cooling / heating process is improved, and the user experience is enhanced.

[0054] Figure 1 This 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.

[0055] Combination Figure 1 As shown, the verification methods for air conditioner self-cleaning include:

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] S102. Based on the historical dust content of the filter or heat exchanger obtained after the previous self-cleaning process, adjust the first preset cooling / heating performance level in the previous self-cleaning confirmation process to the second preset cooling / heating performance level.

[0061] The amount of dust in a filter can be determined by detecting its light transmittance and ventilation; the amount of dust in a heat exchanger can be determined by image recognition and surface reflectivity detection. Those skilled in the art can also select appropriate methods to measure the dust level in the filter or heat exchanger based on the specific circumstances.

[0062] The cooling / heating performance represented by the second preset cooling / heating performance level is lower than that represented by the first preset cooling / heating performance level.

[0063] In the case where the cooling / heating performance level represents 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, the second preset air conditioning operating time represented by the second preset cooling / heating performance level is greater than the first preset air conditioning operating time represented by the first preset cooling / heating performance level, or the second preset air conditioning operating power represented by the second preset cooling / heating performance level is greater than the first preset air conditioning operating power represented by the first preset cooling / heating performance level.

[0064] When the cooling / heating performance level represents the temperature reduction or increase per unit volume of indoor space under a unit operating time and / or unit operating power, the second preset temperature reduction value represented by the second preset cooling / heating performance level is less than the first preset temperature reduction value represented by the first preset cooling / heating performance level; or, the second preset temperature increase value represented by the second preset cooling / heating performance level is less than the first preset temperature increase value represented by the first preset cooling / heating performance level.

[0065] In this embodiment of the application, when the cooling / heating performance represented by the second preset cooling / heating performance level is lower than the cooling / heating performance represented by the cooling / heating performance level threshold, the user is prompted to manually clean the filter or heat exchanger.

[0066] S103. If the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, it is determined that the air conditioner needs to enter the self-cleaning process.

[0067] Among them, the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, including the following situations:

[0068] In the case where the cooling / heating performance level represents 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, the first air conditioning operating time represented by the first cooling / heating performance level is greater than the second preset air conditioning operating time represented by the second preset cooling / heating performance level, or the first air conditioning operating power represented by the first cooling / heating performance level is greater than the second preset air conditioning operating power represented by the second preset cooling / heating performance level.

[0069] When the cooling / heating performance level represents the temperature reduction or increase per unit volume of indoor space under a unit operating time and / or unit operating power, the first temperature reduction value represented by the first cooling / heating performance level is less than the second preset temperature reduction value represented by the second preset cooling / heating performance level; or, the first temperature increase value represented by the first cooling / heating performance level is less than the second preset temperature increase value represented by the second preset cooling / heating performance level.

[0070] Since the overall degree of clogging of the filter or the overall contamination of the heat exchanger will reduce the cooling / heating performance of the air conditioner, the first cooling / heating performance can, to some extent, represent the overall degree of clogging of the filter or the overall contamination of the heat exchanger. However, because many factors such as indoor humidity, indoor air circulation, outdoor ambient temperature, room sealing, refrigerant quantity in the air conditioning system, and the performance of the compressor and fan themselves all affect the cooling / heating performance, using the first cooling / heating performance level determined in the aforementioned steps to represent the overall degree of clogging of the filter or the heat exchanger will have a certain degree of error, and this error is not constant but easily changes.

[0071] The second preset cooling / heating performance level is equivalent to a standard indicator used to measure whether the first cooling / heating performance level meets the standard. Failure to meet the first cooling / heating performance level is due to a combination of factors, including the amount of dust on the filter or heat exchanger.

[0072] Based on the historical dust levels of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the previous self-cleaning confirmation process is adjusted to the second preset cooling / heating performance level. This indicates that the second preset cooling / heating performance level used in this self-cleaning process is relative and variable, and the cooling / heating performance represented by the second preset cooling / heating performance level is lower than that represented by the first preset cooling / heating performance level, indicating that the measurement standard has been lowered in this self-cleaning process.

[0073] Air conditioners have limited self-cleaning capabilities, and a certain amount of dust remains after each cleaning process. When the amount of dust on the filter or heat exchanger increases, the measurement standard for this cleaning process is lowered. For the change in the first cooling / heating performance level caused by factors other than the filter or heat exchanger, the redundant space for compressing the change is not compressed or is reduced. This reduces the phenomenon of the air conditioner frequently entering the self-cleaning process and reduces the impact of the self-cleaning process on indoor temperature fluctuations.

[0074] Through the above methods, this application embodiment reduces the cooling / heating performance slightly in a manner consistent with the self-cleaning capability of the air conditioner, thereby reducing the impact of the self-cleaning process on indoor temperature fluctuations, improving the temperature stability during the air conditioner's cooling / heating process, and enhancing the user experience.

[0075] 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.

[0076] The following is an example of how to determine the first cooling / heating performance level.

[0077] 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 from the first indoor temperature includes: obtaining a first temperature difference between the first indoor temperature and the first set temperature; using the first 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.

[0078] 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.

[0079] 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.

[0080] Those skilled in the art can obtain the correspondence between data sets and cooling / heating performance levels through experimentation.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] In the above embodiments, room volume / area was ignored in determining the first cooling / heating performance level.

[0088] 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.

[0089] 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 first temperature difference between the first indoor temperature and the first set temperature; using the first set temperature, the first 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] The process of obtaining the second preset cooling / heating performance level will be described below by way of example.

[0097] 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.

[0098] The more cooling / heating performance levels there are, the greater the difference in 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 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 air conditioning operating power required to lower / raise the temperature of a unit volume of indoor space by a unit temperature for adjacent cooling / heating performance levels.

[0099] 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.

[0100] Those skilled in the art can set an appropriate number of cooling / heating performance levels according to actual needs.

[0101] Optionally, based on the historical dust amount of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the confirmation process of the last self-cleaning is adjusted to a second preset cooling / heating performance level. This includes: obtaining the first historical dust amount of the filter or heat exchanger after the last self-cleaning process, and the second historical dust amount of the filter or heat exchanger after the self-cleaning process two years prior; obtaining the first performance level increase value corresponding to the difference between the first historical dust amount and the second historical dust amount based on the correspondence between dust amount and performance level increase value; and determining the second preset cooling / heating performance level based on the sum of the first preset cooling / heating performance level and the first performance level increase value.

[0102] The correspondence between dust quantity and performance grade increase indicates the impact of filter or dust quantity on the cooling / heating performance grade of an air conditioner. Those skilled in the art can confirm the correspondence between dust quantity and performance grade increase based on the specific meaning of the selected cooling / heating performance grade and the specific parameters of the air conditioner, using existing air conditioner cooling / heating models, or obtain the correspondence between dust quantity and performance grade increase through experiments.

[0103] The relationship between dust quantity and performance level increase can be expressed by a fitting formula or by a one-to-one correspondence data table. This relationship can be stored in a database. After obtaining the difference between the first and second historical dust quantities, the difference can be substituted into the fitting formula, or the difference can be queried from the database, to obtain the corresponding first performance level increase.

[0104] The sum of the first preset cooling / heating performance level and the increment of the first performance level can be used as the second preset cooling / heating performance level;

[0105] Alternatively, after obtaining the sum of the first preset cooling / heating performance level and the first performance level increment, the sum can be finely adjusted according to the actual situation, and the adjusted value can be used as the second preset cooling / heating performance level.

[0106] Optionally, based on the historical dust amount of the filter or heat exchanger obtained after the previous self-cleaning process, the first preset cooling / heating performance level in the confirmation process of the last self-cleaning is adjusted to a second preset cooling / heating performance level, including: obtaining the first historical dust amount of the filter or heat exchanger after the last self-cleaning process; obtaining the second performance level increase value corresponding to the first historical dust amount according to the correspondence between dust amount and performance level increase value; obtaining the original preset cooling / heating performance level corresponding to the first preset cooling / heating performance level; and determining the second preset cooling / heating performance level based on the sum of the original preset cooling / heating performance level and the second performance level increase value.

[0107] The relationship between dust quantity and performance level increase can be expressed by a fitting formula or by a one-to-one correspondence data table. This relationship can be stored in a database. After obtaining the first historical dust quantity, the difference between the first historical dust quantity and the fitting formula, or by querying the first historical dust quantity in the database, can be used to obtain the second performance level increase corresponding to the first historical dust quantity.

[0108] In this embodiment, the preset cooling / heating performance level consists of two parts: the original preset cooling / heating performance level and the increment value of the cooling / heating performance level.

[0109] The first preset cooling / heating performance level and the second preset cooling / heating performance level correspond to the same original preset cooling / heating performance level.

[0110] The sum of the initial preset cooling / heating performance level and the increase value of the second performance level can be used as the second preset cooling / heating performance level;

[0111] Alternatively, after obtaining the sum of the initial preset cooling / heating performance level and the increase value of the second performance level, a certain fine adjustment can be made according to the actual situation, and the adjusted value can be used as the second preset cooling / heating performance level.

[0112] Optionally, the self-cleaning time of this self-cleaning process is determined based on the difference between the first cooling / heating performance level and the second preset cooling / heating performance level. 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.

[0113] Figure 2This is a flowchart illustrating a method for confirming air conditioner self-cleaning, provided in this application embodiment. It serves as an example to explain the method for determining the self-cleaning duration and its role in the air conditioner self-cleaning process. This method for confirming air conditioner self-cleaning can be executed in the air conditioner's controller, in a mobile terminal such as a remote control, and in a smart home scenario, it can also be executed on a server.

[0114] Combination Figure 2 As shown, the verification methods for air conditioner self-cleaning include:

[0115] S201. 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.

[0116] S202. Based on the historical dust content of the filter or heat exchanger obtained after the historical self-cleaning process, adjust the first preset cooling / heating performance level in the previous self-cleaning confirmation process to the second preset cooling / heating performance level.

[0117] The cooling / heating performance represented by the second preset cooling / heating performance level is lower than that represented by the first preset cooling / heating performance level.

[0118] The cooling / heating performance represented by the second preset cooling / heating performance level is lower than that represented by the first preset cooling / heating performance level.

[0119] S203, Obtain self-cleaning time.

[0120] The self-cleaning time of this self-cleaning process is determined based on the difference between the first cooling / heating performance level and the second preset cooling / heating performance level. The greater the difference between the two, the longer the self-cleaning time, and the smaller the difference between the two, the shorter the self-cleaning time.

[0121] 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.

[0122] When cooling / heating performance is directly represented by a cooling / heating performance level, the self-cleaning time is determined as follows: the first level difference between the first cooling / heating performance level and the second preset cooling / heating performance level is obtained; the self-cleaning time is determined based on the first level difference, and the self-cleaning time is positively correlated with the first level difference.

[0123] 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 first 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 first level corresponding to the same self-cleaning time.

[0124] 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:

[0125] Given a standard temperature difference, obtain the second air conditioner operating time and / or second air conditioner operating power corresponding to the first cooling / heating performance level, and the third air conditioner operating time and / or third air conditioner operating power corresponding to the second preset cooling / heating performance level; obtain a first duration difference between the second and third air conditioner operating times, and / or obtain a first power difference between the second and third air conditioner operating powers; determine the self-cleaning time based on the first duration difference and / or the first power difference, wherein the self-cleaning time is positively correlated with the first duration difference and / or the first power difference;

[0126] or,

[0127] When the temperature difference is the standard temperature difference and the set temperature is the standard set temperature, obtain the fourth air conditioner operating time and / or fourth air conditioner operating power corresponding to the first cooling / heating performance level, and the fourth air conditioner operating time and / or fourth air conditioner operating power corresponding to the second preset cooling / heating performance level; obtain the second duration difference between the fourth air conditioner operating time and the fifth air conditioner operating time, and / or obtain the second power difference between the fourth air conditioner operating power and the fifth air conditioner operating power; determine the self-cleaning time based on the second duration difference and / or the second power difference, and the self-cleaning time is positively correlated with the second duration difference and / or the second power difference.

[0128] When cooling / heating performance is expressed as a decrease or increase in temperature, the self-cleaning time is determined as follows:

[0129] When the air conditioner's operating time and / or operating power are at the standard operating time and / or standard operating power, obtain the second temperature difference value corresponding to the first cooling / heating performance level, and the third temperature difference value corresponding to the preset cooling / heating performance level; determine the self-cleaning time based on the difference between the second temperature difference value and the third temperature difference value; wherein, the difference between the second temperature difference value and the third temperature difference value is positively correlated with the self-cleaning time.

[0130] S204. If the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, it is determined that the air conditioner needs to enter the self-cleaning process.

[0131] After the self-cleaning process has completed the aforementioned self-cleaning duration, the self-cleaning process is terminated.

[0132] During multiple self-cleaning cycles, the cooling / heating performance indicated by the second preset cooling / heating performance level decreases with each cycle. Simultaneously, the air conditioner's self-cleaning capability is limited, leaving a certain amount of dust after each cycle. Therefore, considering only the impact of dust on the filter or heat exchanger on cooling / heating performance, the filter or heat exchanger will cause a continuous decrease in cooling / heating performance with each self-cleaning cycle. However, it is generally assumed that the rate of dust accumulation on the filter or heat exchanger remains roughly constant. The continuous decrease in both the cooling / heating performance indicated by the second preset cooling / heating performance level and the cooling / heating performance caused by the filter or heat exchanger keeps the interval between two self-cleaning cycles relatively fixed. This further reduces the impact of the self-cleaning process on indoor temperature fluctuations, improves temperature stability during air conditioning cooling / heating, and enhances the user experience.

[0133] Figure 3 This is a flowchart illustrating a verification device for air conditioner self-cleaning provided in an embodiment of this application. This verification method for air conditioner self-cleaning can be executed in the air conditioner's controller, in a mobile terminal such as a remote control, and in a smart home scenario, it can also be executed on a server.

[0134] Combination Figure 3 As shown, the verification methods for air conditioner self-cleaning include:

[0135] S301. 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.

[0136] S302. Based on the historical dust content of the filter or heat exchanger obtained after the previous self-cleaning process, adjust the first preset cooling / heating performance level in the previous self-cleaning confirmation process to the second preset cooling / heating performance level.

[0137] The cooling / heating performance represented by the second preset cooling / heating performance level is lower than that represented by the first preset cooling / heating performance level.

[0138] S303. If the cooling / heating performance represented by the first cooling / heating performance level is lower than the cooling / heating performance represented by the second preset cooling / heating performance level, it is determined that the air conditioner needs to enter the self-cleaning process.

[0139] S304. After exiting this self-cleaning process, determine the second cooling / heating performance level of the air conditioner based on the second indoor temperature, the second set temperature, and the sixth air conditioner operating time and / or the sixth air conditioner operating power required to reach the second set temperature from the second indoor temperature.

[0140] 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 and fourth moments is the sixth air conditioner running time.

[0141] Between the third and fourth time points, the average operating power of the air conditioner is the sixth 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 sixth air conditioner operating power.

[0142] 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.

[0143] 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.

[0144] S305. If the first and second cooling / heating performance levels can indicate the degree of improvement of the air conditioner's cooling / heating performance by the executed self-cleaning process, and the preset improvement level is met, the self-cleaning process is determined to be effective, and the air conditioner continues to operate.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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 extended, or the user can be prompted to manually clean or replace the filter, or the heat exchanger can be manually cleaned.

[0152] The following is an exemplary description of the process for determining the second cooling / heating performance level.

[0153] 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 fourth temperature difference between the second indoor temperature and the second set temperature; using the fourth 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.

[0154] 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.

[0155] 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.

[0156] 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;

[0157] 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;

[0158] 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;

[0159] 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;

[0160] 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;

[0161] 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.

[0162] 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.

[0163] In the above embodiments, room volume / area was ignored in determining the second cooling / heating performance level.

[0164] 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.

[0165] The following is an example illustrating the extent to which this self-cleaning process improves the air conditioner's cooling / heating performance, meeting the preset improvement level.

[0166] 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 the second 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 second level difference is greater than or equal to the first difference threshold; wherein, the more performance levels there are, the larger the first difference threshold is.

[0167] 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.

[0168] 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 second 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 second temperature difference value and the fifth temperature difference value is greater than or equal to the second difference threshold value.

[0169] The second temperature difference and the fifth temperature difference can both be values ​​that decrease in temperature; or, the second temperature difference and the fifth temperature difference can both be values ​​that increase in temperature.

[0170] 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.

[0171] 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.

[0172] 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 second air conditioner operating time and / or the second air conditioner operating power corresponding to the first cooling / heating performance level, and the seventh air conditioner operating time and / or the seventh 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 third duration difference between the third and seventh air conditioner operating times is greater than or equal to a first duration threshold, and / or the third power difference between the third and seventh 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.

[0173] 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.

[0174] 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 fourth air conditioner operating time and / or fourth air conditioner operating power corresponding to the first cooling / heating performance level, and the eighth air conditioner operating time and / or eighth air conditioner operating power corresponding to the second cooling / heating performance level, when 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 fourth duration difference between the fourth and eighth air conditioner operating times is greater than or equal to a second duration threshold, and / or the fourth power difference between the fourth and eighth 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.

[0175] 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.

[0176] Figure 4 This is a schematic diagram of a confirmation device for air conditioner self-cleaning provided in an embodiment of this application. This confirmation device for air conditioner self-cleaning can be implemented through software, hardware, or a combination of both. Figure 4 As shown, the confirmation device for air conditioner self-cleaning includes a first determination module 41, an acquisition module 42, and a second determination module 43.
