[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure 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 so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] The acquisition, storage, use, and processing of data in this disclosed technical solution all comply with the relevant provisions of national laws and regulations.

[0032] Figure 1 This is a flowchart illustrating a control method for an air conditioner according to an exemplary embodiment, such as... Figure 1 As shown, the control method of the air conditioner in this embodiment includes the following steps.

[0033] S101, get the current PM2.5 value.

[0034] It should be noted that the execution subject of the air conditioner control method in this embodiment is an electronic device or an air conditioner. Electronic devices include mobile phones, laptops, desktop computers, vehicle terminals, smart home appliances, etc. The air conditioner control method in this embodiment can be executed by the air conditioner control device, which can be configured in any electronic device or any air conditioner to execute the air conditioner control method.

[0035] It should be noted that the current PM2.5 value refers to the current outdoor PM2.5 value.

[0036] In one implementation, taking an air conditioner as an example, the air conditioner is equipped with a communication module to obtain the current PM2.5 value, including querying the current PM2.5 value through the communication module. It should be noted that the communication module is not overly limited; for example, it may include a wireless communication module (such as Bluetooth).

[0037] S102, if the current PM2.5 value is less than the preset threshold, then further obtain the user's current time period and / or indoor carbon dioxide concentration, and determine whether to turn on the fresh air function of the air conditioner based on the user's current time period and / or indoor carbon dioxide concentration.

[0038] It should be noted that the preset threshold is not subject to many restrictions; for example, it can be 100. .

[0039] Understandably, a 24-hour day can be divided into multiple time periods in advance, without much restriction on the method of division. For example, it can be divided into 0:00 to 3:00, 3:00 to 7:00, 7:00 to 10:00, 10:00 to 14:00, 14:00 to 16:00, 16:00 to 21:00, and 21:00 to 24:00, for a total of 7 time periods.

[0040] In one implementation, taking an air conditioner as the executing entity, the air conditioner is equipped with a clock module to obtain the user's current time period, including obtaining the current time through the clock module and determining the time period of the current time as the user's current time period.

[0041] In one implementation, taking an air conditioner as an example, the indoor unit of the air conditioner is equipped with a carbon dioxide sensor to detect the indoor carbon dioxide concentration and obtain the indoor carbon dioxide concentration, including obtaining the indoor carbon dioxide concentration through the carbon dioxide sensor.

[0042] In one implementation, determining whether to turn on the fresh air function of the air conditioner based on the user's current time period and / or indoor carbon dioxide concentration includes determining whether the user's current time period is a target time period and / or whether the indoor carbon dioxide concentration is greater than or equal to a first threshold. If the user's current time period is a target time period and / or the indoor carbon dioxide concentration is greater than or equal to the first threshold, then it is determined that the fresh air function of the air conditioner will be turned on.

[0043] Conversely, if the user's current time period is not the target time period, and / or the indoor carbon dioxide concentration is less than the first threshold, then the fresh air function of the air conditioner will be turned off.

[0044] It should be noted that there are no strict restrictions on the target time period. For example, it can include the user's off-get off work time, such as 4 PM to 9 PM.

[0045] It should be noted that the first threshold is not subject to many restrictions; for example, it can be 1200. .

[0046] For example, if the target time period is from 4 PM to 9 PM, the first threshold is 1200. If the user is currently in a time period from 4 PM to 9 PM, and the indoor carbon dioxide concentration is 900... If the user's current time period is the target time period, then the fresh air function of the air conditioner can be activated. Therefore, this method can activate the fresh air function of the air conditioner when the user's current time period is the target time period. This is particularly suitable for scenarios where the indoor carbon dioxide concentration is low when the user returns home from get off work. Compared to related technologies that only activate the fresh air function when the indoor carbon dioxide concentration is high, this solution can activate the fresh air function even when the indoor carbon dioxide concentration is low, making it more flexible.

[0047] For example, if the target time period is from 4 PM to 9 PM, the first threshold is 1200. If the user is currently in a time period from 9 PM to midnight, and the indoor carbon dioxide concentration is 1300... If the indoor carbon dioxide concentration is greater than a first threshold, the fresh air function of the air conditioner can be activated. Therefore, this method allows the air conditioner's fresh air function to be activated when the indoor carbon dioxide concentration is high.

[0048] For example, if the target time period is from 4 PM to 9 PM, the first threshold is 1200. If the user is currently in a time period from 9 PM to midnight, and the indoor carbon dioxide concentration is 900... If the target time period is currently in the user's current time period and the indoor carbon dioxide concentration is less than the first threshold, then the fresh air function of the air conditioner will be turned off.

[0049] The air conditioner control method provided in this disclosure acquires the current PM2.5 value. If the current PM2.5 value is less than a preset threshold, it further acquires the user's current time period and / or indoor carbon dioxide concentration, and determines whether to activate the air conditioner's fresh air function based on the user's current time period and / or indoor carbon dioxide concentration. Therefore, this solution can determine whether to activate the air conditioner's fresh air function when the current PM2.5 value is low, i.e., when the outdoor air quality is good, by comprehensively considering the user's current time period and / or indoor carbon dioxide concentration. This improves the flexibility of activating the fresh air function, helps improve indoor air quality, and extends the service life of the fresh air filter.

[0050] Figure 2 This is a flowchart illustrating a control method for an air conditioner according to another exemplary embodiment, such as... Figure 2 As shown, the control method of the air conditioner in this embodiment includes the following steps.

[0051] S201, Get the current PM2.5 value.

[0052] S202, if the current PM2.5 value is less than the preset threshold, then further obtain the user's current time period and / or indoor carbon dioxide concentration.

[0053] For details regarding steps S201-S202, please refer to the above embodiments, which will not be repeated here.

[0054] S203 generates a first comparison table based on historical data of the user's fresh air switch status and operating time percentage in multiple time periods and multiple carbon dioxide ranges.

[0055] Understandably, the range of carbon dioxide concentration can be pre-divided into multiple carbon dioxide intervals, without much restriction on the method of division. For example, it can be divided into intervals above 1800... 1500 By 1800 1200 Up to 1500 900 Up to 1200 500 Up to 900 Below 500 .

[0056] It is understandable that the fresh air switch status can include both "on" and "off" states. The percentage of runtime can include the percentage of runtime when the fresh air switch is "on" or "off" across multiple time periods and carbon dioxide levels. Specifically, the percentage of runtime when the fresh air switch is "on" refers to the proportion of the total runtime when the fresh air switch is "on" across multiple time periods and carbon dioxide levels to the total operating time of the air conditioner. The percentage of runtime when the fresh air switch is "off" refers to the proportion of the total runtime when the fresh air switch is "off" across multiple time periods and carbon dioxide levels to the total operating time of the air conditioner.

[0057] In one implementation, the first lookup table includes the correspondence between multiple time periods and multiple carbon dioxide intervals and the user's fresh air preference. The first lookup table is generated based on historical data of the user's fresh air switch status and the percentage of time spent in each of the multiple time periods and multiple carbon dioxide intervals. If the percentage of time spent in each of the time periods and carbon dioxide intervals with the fresh air switch on is greater than or equal to the percentage of time spent in each of the time periods with the fresh air switch on is off, then the user's fresh air preference for the corresponding time period and carbon dioxide interval is "on". Conversely, if the percentage of time spent in each of the time periods and carbon dioxide intervals with the fresh air switch on is less than the percentage of time spent in each of the time periods with the fresh air switch on is off, then the user's fresh air preference for the corresponding time period and carbon dioxide interval is "off".

[0058] In some cases, the first lookup table is shown in Table 1.

[0059] Table 1 First Comparison Table

[0060] For example, continuing with Table 1, we can observe that users' carbon dioxide levels were above 1800 between 0:00 and 3:00. The percentage of time the fresh air system was in "on" or "off" state indicates that 80% of the time was spent in "on" mode and 20% in "off" mode. Therefore, the carbon dioxide level was above 1800 during the period from 0:00 to 3:00. The corresponding user's preference for fresh air is "on".

[0061] For example, continuing with Table 1, we can calculate the carbon dioxide level for users between 0:00 and 3:00 by analyzing the data. Up to 1500 The percentage of time the fresh air system was in "on" or "off" state indicates that 5% of the time was spent in "on" mode and 95% was spent in "off" mode. Therefore, the carbon dioxide level was between 1200 and 3 AM. Up to 1500 The corresponding user's preference for fresh air is "off".

[0062] In one implementation, the runtime of the fresh air system with the air conditioner switch "on" can be weighted and summed to obtain the total runtime of the fresh air system with the air conditioner switch "on". It should be noted that the weights are related to the dates corresponding to the historical timestamps; the closer the historical time is to the current time, the higher the weight; conversely, the further away the historical time is from the current time, the lower the weight. For example, if the current date is August 8th, then the runtime of the fresh air system with the air conditioner switch "on" on August 7th has a weight of 5, the runtime of the fresh air system with the air conditioner switch "on" on August 6th has a weight of 3, the runtime of the fresh air system with the air conditioner switch "on" on August 5th has a weight of 1, the runtime of the fresh air system with the air conditioner switch "on" on August 4th has a weight of 1, and the runtime of the fresh air system with the air conditioner switch "on" on August 3rd has a weight of 0.5.

[0063] It is understandable that the method for obtaining the total runtime when the fresh air switch is in the "off" state can refer to the method for obtaining the total runtime when the fresh air switch is in the "on" state in the above embodiment, and will not be repeated here.

[0064] S204. Based on the user's current time period and indoor carbon dioxide concentration, consult the first reference table to determine whether to turn on the air conditioner's fresh air function.

[0065] Understandably, if the user's fresh air preference is "off", then the fresh air function of the air conditioner will be turned off; if the user's fresh air preference is "on", then the fresh air function of the air conditioner will be turned on.

[0066] For example, continuing with Table 1, if the user's current time period is from 0:00 to 3:00, and the indoor carbon dioxide concentration is 1300... Then, based on the user's current time period and indoor carbon dioxide concentration, Table 1 can be consulted. At this time, the indoor carbon dioxide concentration falls within the range of 1200. Up to 1500 It can be seen that the carbon dioxide level is between 1200 and 3:00. Up to 1500 If the user's fresh air preference is "off", then the fresh air function of the air conditioner can be turned off.

[0067] For example, continuing with Table 1, if the user's current time period is from 3 AM to 7 AM, and the indoor carbon dioxide concentration is 1000... Then, based on the user's current time period and indoor carbon dioxide concentration, Table 1 can be consulted. At this time, the indoor carbon dioxide concentration falls within the range of 900. Up to 1200 It can be seen that the carbon dioxide level is between 3 AM and 7 AM, and the range is 900. Up to 1200 If the user's fresh air preference is "on", then the fresh air function of the air conditioner can be turned on.

[0068] The air conditioner control method provided in the embodiments of this disclosure can generate a first lookup table based on historical data of the user's fresh air switch status and running time percentage in multiple time periods and multiple carbon dioxide ranges, and query the first lookup table according to the user's current time period and indoor carbon dioxide concentration to determine whether to turn on the fresh air function of the air conditioner.

[0069] Figure 3 This is a flowchart illustrating a control method for an air conditioner according to another exemplary embodiment, such as... Figure 3 As shown, the control method of the air conditioner in this embodiment includes the following steps.

[0070] S301, get the current PM2.5 value.

[0071] S302, if the current PM2.5 value is less than the preset threshold, then further obtain the user's current time period and / or indoor carbon dioxide concentration.

[0072] S303 generates a first comparison table based on historical data of the user's fresh air switch status and operating time percentage in multiple time periods and multiple carbon dioxide ranges.

[0073] S304. Based on the user's current time period and indoor carbon dioxide concentration, consult the first reference table to determine whether to turn on the air conditioner's fresh air function.

[0074] For details regarding steps S301-S304, please refer to the above embodiments, which will not be repeated here.

[0075] S305 generates a second comparison table based on historical data of the user's fresh air switch status and operating time percentage in multiple carbon dioxide ranges.

[0076] It should be noted that the relevant information regarding the carbon dioxide range and the status of the fresh air switch can be found in the above embodiments, and will not be repeated here.

[0077] Understandably, the percentage of runtime can include the percentage of runtime when the user's fresh air switch is "on" or "off" across multiple carbon dioxide levels. Specifically, the percentage of runtime when the fresh air switch is "on" refers to the proportion of the total runtime when the user's fresh air switch is "on" across multiple carbon dioxide levels to the total operating time of the air conditioner. The percentage of runtime when the fresh air switch is "off" refers to the proportion of the total runtime when the user's fresh air switch is "off" across multiple carbon dioxide levels to the total operating time of the air conditioner.

[0078] In one implementation, the second lookup table includes a correspondence between multiple carbon dioxide ranges and user fresh air preferences. The second lookup table is generated based on historical data of the user's fresh air switch status and the percentage of time spent in each of the multiple carbon dioxide ranges. If the percentage of time spent in a carbon dioxide range with the fresh air switch on is greater than or equal to the percentage of time spent with the fresh air switch off is off, then the user's fresh air preference for the corresponding carbon dioxide range is "on". Conversely, if the percentage of time spent in a carbon dioxide range with the fresh air switch on is less than the percentage of time spent with the fresh air switch off is off, then the user's fresh air preference for the corresponding carbon dioxide range is "off".

[0079] In some cases, a second lookup table is shown in Table 2.

[0080] Table 2 Second Comparison Table

[0081] For example, continuing with Table 2, we can statistically analyze users whose carbon dioxide levels are above 1800. The percentage of runtime when the fresh air switch was "on" or "off" indicates that 80% of the runtime was with the switch "on" and 20% was with the switch "off." This suggests that the carbon dioxide level was above 1800. The corresponding user's preference for fresh air is "on".

[0082] For example, continuing with Table 2, we can statistically analyze the user's carbon dioxide level in the range of 1200. Up to 1500 The percentage of runtime when the fresh air switch is in "on" or "off" indicates that the runtime when the fresh air switch is in "on" is 5%, and the runtime when the fresh air switch is in "off" is 95%. Therefore, the carbon dioxide level is in the range of 1200. Up to 1500 The corresponding user's preference for fresh air is "off".

[0083] S306 If it cannot be determined whether to turn on the fresh air function of the air conditioner in the first lookup table, consult the second lookup table according to the indoor carbon dioxide concentration to determine whether to turn on the fresh air function of the air conditioner.

[0084] For example, continuing with Tables 1 and 2, if the user's current time period is from 9 PM to midnight, and the indoor carbon dioxide concentration is 1600... Then, based on the user's current time period and indoor carbon dioxide concentration, Table 1 can be consulted. At this time, the indoor carbon dioxide concentration falls within the range of 1500. By 1800 If the time period from 9 PM to midnight cannot be determined in Table 1, the carbon dioxide range is 1200. Up to 1500 For users whose fresh air preferences are not specified in Table 1 (i.e., whether to turn on the air conditioner's fresh air function), they can refer to Table 2 based on the indoor carbon dioxide concentration, which shows a carbon dioxide range of 1200. Up to 1500 If the user's fresh air preference is "off", then the fresh air function of the air conditioner can be turned off.

[0085] The air conditioner control method provided in the embodiments of this disclosure can generate a second lookup table based on historical data of the user's fresh air switch status and running time percentage in multiple carbon dioxide ranges. If it cannot be determined whether to turn on the fresh air function of the air conditioner in the first lookup table, the second lookup table can be consulted based on the indoor carbon dioxide concentration to determine whether to turn on the fresh air function of the air conditioner. That is, the query order is "first lookup table - second lookup table".

[0086] Figure 4This is a flowchart illustrating a control method for an air conditioner according to another exemplary embodiment, such as... Figure 4 As shown, the control method of the air conditioner in this embodiment includes the following steps.

[0087] S401, retrieve the current PM2.5 value.

[0088] S402, if the current PM2.5 value is less than the preset threshold, then further obtain the user's current time period and / or indoor carbon dioxide concentration.

[0089] S403 generates a first comparison table based on historical data of the user's fresh air switch status and operating time percentage in multiple time periods and multiple carbon dioxide ranges.

[0090] S404: Based on the user's current time period and indoor carbon dioxide concentration, consult the first reference table to determine whether to turn on the air conditioner's fresh air function.

[0091] S405 generates a second comparison table based on historical data of the user's fresh air switch status and operating time percentage in multiple carbon dioxide ranges.

[0092] S406 If it cannot be determined whether to turn on the fresh air function of the air conditioner in the first lookup table, consult the second lookup table according to the indoor carbon dioxide concentration to determine whether to turn on the fresh air function of the air conditioner.

[0093] For details regarding steps S401-S406, please refer to the above embodiments; they will not be repeated here.

[0094] S407 generates a third reference table based on historical data of the user's fresh air switch status and running time percentage over multiple time periods.

[0095] It should be noted that the relevant information regarding time periods and the status of the fresh air switch can be found in the above embodiments, and will not be repeated here.

[0096] Understandably, the percentage of runtime can include the percentage of runtime when the fresh air switch is "on" or "off" across multiple time periods. Specifically, the percentage of runtime when the fresh air switch is "on" refers to the proportion of the total runtime when the fresh air switch is "on" across multiple time periods to the total operating time of the air conditioner. The percentage of runtime when the fresh air switch is "off" refers to the proportion of the total runtime when the fresh air switch is "off" across multiple time periods to the total operating time of the air conditioner.

[0097] In one implementation, the third lookup table includes the correspondence between multiple time periods and users' fresh air preferences. The third lookup table is generated based on historical data of the user's fresh air switch status and the percentage of time spent in each of the multiple time periods. If the percentage of time spent in which the user's fresh air switch is "on" is greater than or equal to the percentage of time spent in which the user's fresh air switch is "off" during a time period, then the user's fresh air preference for that time period is "on". Conversely, if the percentage of time spent in which the user's fresh air switch is "on" is less than the percentage of time spent in which the user's fresh air switch is "off" during a time period, then the user's fresh air preference for that time period is "off".

[0098] In some cases, the third lookup table is shown in Table 3.

[0099] Table 3 Third Comparison Table

[0100] For example, continuing with Table 3, by statistically analyzing the percentage of time users spent with the fresh air switch on or off during the time period from 0:00 to 3:00, we can see that the percentage of time spent with the fresh air switch on is 80% and the percentage of time spent with the fresh air switch off is 20%. Therefore, we can conclude that the user's preference for the fresh air system during the time period from 0:00 to 3:00 is "on".

[0101] For example, continuing with Table 3, by statistically analyzing the percentage of time users spent with the fresh air switch on or off between 3 AM and 7 AM, we can see that the percentage of time spent with the fresh air switch on is 30% and the percentage of time spent with the fresh air switch off is 70%. Therefore, we can conclude that the user's preference for the fresh air system between 3 AM and 7 AM is "off".

[0102] S408 If it cannot be determined whether the fresh air function of the air conditioner is turned on in the second lookup table, the third lookup table is consulted according to the user's current time period to determine whether the fresh air function of the air conditioner is turned on.

[0103] For example, continuing with Tables 1 to 3, if the user's current time period is from 9 PM to midnight, and the indoor carbon dioxide concentration is 800... Then, based on the user's current time period and indoor carbon dioxide concentration, Table 1 can be consulted. At this time, the indoor carbon dioxide concentration falls within the range of 500. Up to 900 If the time period from 9 PM to midnight cannot be determined in Table 1, the carbon dioxide range is 500. Up to 900μ For users whose fresh air preferences cannot be determined in Table 1 (i.e., whether to turn on the air conditioner's fresh air function), please refer to Table 2 based on the indoor carbon dioxide concentration. If the carbon dioxide concentration cannot be determined in Table 2, the range is 500. Up to 900 For users whose fresh air preferences cannot be determined in Table 2, Table 3 can be consulted based on the user's current time period. It can be found that the user's fresh air preference for the time period from 9 PM to midnight is "on", so it can be determined that the fresh air function of the air conditioner is on.

[0104] The air conditioner control method provided in the embodiments of this disclosure can generate a third lookup table based on historical data of the user's fresh air switch status and running time percentage in multiple time periods. If it cannot be determined whether the fresh air function of the air conditioner is turned on in the first and second lookup tables, the third lookup table can be queried according to the user's current time period to determine whether the fresh air function of the air conditioner is turned on. That is, the query order is "first lookup table - second lookup table - third lookup table".

[0105] It should be noted that the first, second, and third lookup tables can be generated in advance or in real time. No further restrictions are imposed here. Step S203 can be executed before steps S201-S202, steps S303 and S305 can be executed before steps S301-S302, and steps S403, S405, and S407 can be executed before steps S401-S402.

[0106] Based on any of the above embodiments, the method further includes turning off the fresh air function if it cannot be determined whether the fresh air function of the air conditioner is turned on in the first to the third lookup tables.

[0107] It should be noted that Tables 1 to 3 are only examples of the first to third comparison tables, and there may be other implementations of the first to third comparison tables.

[0108] In one implementation, the first lookup table includes the correspondence between multiple time periods and carbon dioxide ranges within N1 days and the user's fresh air preferences; the second lookup table includes the correspondence between multiple time periods and carbon dioxide ranges within N2 days and the user's fresh air preferences; and the third lookup table includes the correspondence between multiple time periods and carbon dioxide ranges within N3 days and the user's fresh air preferences, where N1≤N2≤N3, for example, N1=3, N2=5, N3=10. Thus, the first lookup table reflects the user's latest fresh air preferences. Users can first check the first lookup table based on their current time period and indoor carbon dioxide concentration to determine whether to turn on the air conditioner's fresh air function according to their latest preferences. If the first lookup table fails to determine whether to turn on the air conditioner's fresh air function, the second lookup table can be checked. If the second lookup table also fails to determine whether to turn on the air conditioner's fresh air function, the third lookup table can be checked. The query order is "first lookup table – second lookup table – third lookup table".

[0109] Figure 5 This is a flowchart illustrating a control method for an air conditioner according to another exemplary embodiment, such as... Figure 5 As shown, the control method of the air conditioner in this embodiment includes the following steps.

[0110] S501, retrieve the current PM2.5 value.

[0111] For details regarding step S501, please refer to the above embodiments, which will not be repeated here.

[0112] S502, if the current PM2.5 value is greater than or equal to the preset threshold, then further determine whether a command to turn on the fresh air function of the air conditioner has been received.

[0113] S503: If a command to turn on the fresh air function of the air conditioner is received, then the fresh air function is turned on.

[0114] S504: If no instruction to turn on the fresh air function of the air conditioner is received, then the fresh air function is turned off.

[0115] Understandably, users can issue commands to activate the fresh air function of the air conditioner via remote control, touch buttons on the air conditioner unit, or the air conditioner app on the terminal.

[0116] In one implementation, before determining whether a command to turn on the air conditioner's fresh air function has been received, the system further includes controlling the display to ask the user whether to turn on the fresh air function. For example, the information "whether to turn on the fresh air function" can be displayed on the remote control, the display screen on the air conditioner unit, or the air conditioner app on the terminal.

[0117] In one implementation, if a command to activate the air conditioner's fresh air function is received, the system also includes a control display to remind the user of a high PM2.5 level, indicating poor air quality. If a cancellation command is received, the fresh air function is deactivated; otherwise, if no cancellation command is received, the fresh air function is activated. It is understood that the user may cancel the activation command after seeing the above information.

[0118] The air conditioner control method provided in this disclosure obtains the current PM2.5 value. If the current PM2.5 value is greater than or equal to a preset threshold, it further determines whether a command to activate the air conditioner's fresh air function has been received, and determines whether to activate the fresh air function based on whether the command has been received. Therefore, this solution can determine whether to activate the air conditioner's fresh air function based on the user's command when the current PM2.5 value is high, i.e., when the outdoor air quality is poor, thus improving the flexibility of activating the fresh air function.

[0119] Figure 6 This is a block diagram illustrating a control device for an air conditioner according to an exemplary embodiment. (Refer to...) Figure 6 The control device 100 for an air conditioner according to this embodiment includes: an acquisition module 110 and a judgment module 120.

[0120] The acquisition module 110 is configured to acquire the current PM2.5 value; The judgment module 120 is configured to activate the fresh air function of the air conditioner if the current PM2.5 value is greater than or equal to a preset threshold. The judgment module 120 is further configured to, if the current PM2.5 value is less than a preset threshold, further obtain the user's current time period and / or indoor carbon dioxide concentration, and determine whether to turn on the fresh air function of the air conditioner based on the user's current time period and / or indoor carbon dioxide concentration.

[0121] In one embodiment of this disclosure, the judgment module 120 is further configured to perform: generating a first lookup table based on historical data of the user's fresh air switch status and running time percentage in multiple time periods and multiple carbon dioxide ranges; querying the first lookup table based on the user's current time period and the indoor carbon dioxide concentration to determine whether to turn on the fresh air function of the air conditioner.

[0122] In one embodiment of this disclosure, the determination module 120 is further configured to: generate a second lookup table based on historical data of the user's fresh air switch status and running time percentage in the multiple carbon dioxide ranges; if it cannot be determined whether the fresh air function of the air conditioner is turned on in the first lookup table, query the second lookup table based on the indoor carbon dioxide concentration to determine whether the fresh air function of the air conditioner is turned on.

[0123] In one embodiment of this disclosure, the judgment module 120 is further configured to: generate a third lookup table based on historical data of the user's fresh air switch status and running time percentage during the multiple time periods; if it cannot be determined whether the fresh air function of the air conditioner is turned on in the second lookup table, query the third lookup table based on the user's current time period to determine whether the fresh air function of the air conditioner is turned on.

[0124] In one embodiment of this disclosure, the determination module 120 is further configured to perform the following: if it cannot be determined whether the fresh air function of the air conditioner is turned on in the first lookup table to the third lookup table, then the fresh air function is turned off.

[0125] In one embodiment of this disclosure, the judgment module 120 is further configured to: if the current PM2.5 value is greater than or equal to the preset threshold, further determine whether an instruction to turn on the fresh air function of the air conditioner has been received; if an instruction to turn on the fresh air function of the air conditioner has been received, then turn on the fresh air function; or, if no instruction to turn on the fresh air function of the air conditioner has been received, then turn off the fresh air function.

[0126] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0127] The air conditioner control device provided in the embodiments of this disclosure acquires the current PM2.5 value. If the current PM2.5 value is less than a preset threshold, it further acquires the user's current time period and / or indoor carbon dioxide concentration, and determines whether to activate the air conditioner's fresh air function based on the user's current time period and / or indoor carbon dioxide concentration. Therefore, this solution can determine whether to activate the air conditioner's fresh air function when the current PM2.5 value is low, i.e., when the outdoor air quality is good, by comprehensively considering the user's current time period and / or indoor carbon dioxide concentration. This improves the flexibility of activating the fresh air function, helps improve indoor air quality, and extends the service life of the fresh air filter.
