[0002] After the air conditioner has finished cooling, a lot of condensation can easily remain on the evaporator. If it is not dried in time, it can easily lead to the growth of bacteria and mold on the evaporator and even other parts inside the unit, which can seriously affect the health of users.

[0003] Currently, most common drying modes on the market involve heating the evaporator and then using an internal fan to blow away the condensate. However, when the drying mode of these air conditioners is activated, the inability to accurately control the drying process results in low control accuracy during the air conditioner's drying process. Summary of the Invention

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0068] The air conditioning control method provided in this application embodiment can be applied to, for example... Figure 1 The application environment is shown. The air conditioner 100 includes a control motherboard 102, an indoor unit data acquisition module 104 mounted on the control motherboard 102, and a target control module 106. The indoor unit data acquisition module 104 acquires the real-time indoor pipe temperature when the air conditioner's drying mode is activated. Specifically, the indoor unit data acquisition module can obtain the real-time indoor pipe temperature through a temperature sensor when the air conditioner's drying mode is activated. The target control module 106 obtains the compressor frequency correction value based on the current temperature difference between the real-time indoor pipe temperature and the target indoor pipe temperature; adjusts the compressor's operating frequency according to the frequency correction value; and controls the air conditioner to exit the drying mode when the drying stop conditions are met.

[0069] In one embodiment, such as Figure 2 As shown, the control mainboard 102 includes an indoor unit mainboard 202 and an outdoor unit mainboard 204, with the indoor unit data acquisition module 104 mounted on the indoor unit mainboard 202. The target control module 106 includes an indoor unit drying mode control module 2021 mounted on the indoor unit mainboard 202 and an outdoor unit drying mode control module 2041 mounted on the outdoor unit mainboard 204. The indoor unit data acquisition module 102 collects user commands to activate the drying mode, and the indoor unit drying mode control module then activates the air conditioner's drying mode based on these commands. The indoor unit drying mode control module 2021 obtains the compressor's frequency correction value based on the current temperature difference between the real-time indoor pipe temperature and the target indoor pipe temperature. The outdoor unit drying mode control module 2041 adjusts the compressor's operating frequency based on the frequency correction value. The indoor unit drying mode control module 2021 also controls the air conditioner to exit the drying mode when the drying stop conditions are met.

[0070] The indoor motherboard 202 and the outdoor motherboard 204 can communicate in various ways, as long as the indoor motherboard 202 can transmit the frequency correction value to the outdoor motherboard 204.

[0071] exist Figure 2 Based on the above, in one embodiment, as shown Figure 3 The diagram shows a structural block diagram of an air conditioner. The air conditioner 100 also includes an indoor unit communication module 302 mounted on the indoor unit main board 202, and an outdoor unit communication module 304 and an outdoor unit data acquisition module 306 mounted on the outdoor unit main board 204.

[0072] The indoor unit data acquisition module 104 is also used to acquire the indoor ambient temperature collected by the temperature sensor. The indoor unit data acquisition module 104 communicates with the indoor unit drying mode control module 2021 through the indoor unit communication module 302. Specifically, the indoor unit data acquisition module 104 transmits the indoor pipe temperature to the indoor unit drying mode control module 2021 through the indoor unit communication module 302. The indoor unit drying mode control module 2021 is also used to control the air guide structure and the speed of the indoor fan when the air conditioner's drying mode is activated. The indoor unit communication module 302 is also responsible for communicating with the outdoor unit communication module 304 to share parameters, such as sharing the indoor pipe temperature and indoor ambient temperature collected by the temperature sensor. The indoor unit communication module 302 is also used to transmit frequency correction values ​​to the outdoor unit communication module 304.

[0073] The outdoor unit data acquisition module 306 is used to acquire the outdoor ambient temperature through a temperature sensor. The outdoor unit communication module 304 is responsible for communicating with the indoor unit communication module 302 to share parameters, such as the outdoor ambient temperature. The outdoor unit drying mode control module 2041 is also used to control at least one of the compressor, outdoor fan, and expansion valve according to the required indoor pipe temperature when the air conditioner's drying mode is activated. For example, the outdoor unit drying mode control module 2041 is used to adjust the compressor's operating frequency according to a frequency correction value.

[0074] While air conditioners on the target market can achieve drying by heating the evaporator and then using an indoor fan to blow away the condensate, this drying process is problematic. With the air deflector open, the fan maintains a high speed, resulting in significant noise and hot air being blown out. This not only affects the indoor temperature and reduces user comfort but also gives users the illusion that the unit hasn't been turned off in time, leading to complaints. Conversely, if the air deflector is turned to the anti-direct-blow position or closed, there will be virtually no airflow from the indoor unit. The evaporated moisture will remain inside the unit casing, and because the internal pressure cannot be released in time, system operating parameters will become unstable, the compressor will run erratically, and ultimately, the unit will shut down as a safety precaution.

[0075] Based on this, when the air conditioner's drying mode is turned on, the indoor unit's drying mode control module 2021 can control the air guide structure through various possible circuit structures. As long as it can achieve the goal of expelling the high-humidity air generated inside the indoor unit casing during drying by using the air guide plate closure method, thus ensuring the drying effect while improving user comfort, it is acceptable.

[0076] In one embodiment, the air conditioner 100 may further include an air guide vane, a fan, an exhaust duct assembly, and a fresh air duct. The air guide structure includes the exhaust duct assembly and the fresh air duct. The indoor unit drying mode control module 2021 is also used to control the air guide vane to close and the fan to start when the air conditioner's drying mode is activated. The exhaust duct assembly is used to absorb moisture from the indoor unit of the air conditioner when the drying mode is activated; the fresh air duct is used to exhaust the moisture outdoors. Therefore, when the air conditioner's drying function is achieved by closing the air guide vane, the exhaust duct assembly and fresh air duct prevent evaporated moisture from remaining in the indoor unit casing. This avoids the situation where internal pressure cannot be released in time, which could easily cause unstable operation of the air conditioner and lead to a protective shutdown, thus improving the stability of the air conditioner during drying mode operation.

[0077] The exhaust duct assembly can be implemented using various possible structures, as long as it can absorb the water vapor evaporated in the indoor unit of the air conditioner when the air conditioner's dry mode is turned on.

[0078] In one embodiment, the exhaust duct assembly includes an exhaust duct and a rotary valve, and the air guide structure includes the rotary valve. For example... Figure 4 As shown, Figure 4 This is an overall structural diagram of the exhaust pipe assembly 400. Figure 4 On the basis of, such as Figure 5 As shown, the exhaust pipe assembly 400 includes an upper pipe 5021 and a lower pipe 5022 of the exhaust pipe 502, and a rotary valve 504. When the air conditioner's drying mode is activated, the indoor unit drying mode control module 2012 controls the rotary valve 504 to rotate to... Figure 6 In the second position 602, the rotation angle of the rotary valve is a preset angle, which is any angle between 20° and 160°. When the air conditioner's drying mode is not activated, the indoor unit drying mode control module 2021 controls the rotary valve to rotate to... Figure 6In the first position 604, the valve 504 is rotated parallel to the inlet of the exhaust pipe 502, completely sealing the inlet of the exhaust pipe 502 and preventing airflow from the unit from being discharged through it. Therefore, when the drying function is achieved by controlling the air conditioner's air deflector to close and the fan to start, moisture in the indoor unit can be absorbed through the exhaust pipe and discharged outdoors through the fresh air duct. This avoids the situation where evaporated moisture remains in the indoor unit casing, causing unstable operation and potential shutdown due to insufficient internal pressure, thus improving the stability of the air conditioner during drying mode.

[0079] In one embodiment, the air conditioner further includes a fresh air connector connected to a fresh air duct, through which moisture absorbed by the exhaust duct assembly enters the fresh air duct. The air guiding structure includes the fresh air connector.

[0080] In one embodiment, the air conditioner further includes a fresh air baffle and a fresh air inlet cavity, and the air guiding structure includes the fresh air baffle and the fresh air inlet cavity. Specifically, the fresh air baffle is used to close the fresh air inlet cavity when the air conditioner's drying mode is activated. Thus, when the fresh air baffle closes the fresh air inlet cavity, a channel is formed between the inside of the air conditioner and the outside. At this time, closing the air conditioner's air guide plate and turning on the fan allows the moisture in the air inside the unit to be discharged to the outside through the exhaust pipe.

[0081] In summary, such as Figure 7 The diagram illustrates the structure of an air conditioner. The air conditioner 100 includes an exhaust duct 502, a rotary valve 504, a fresh air connector 702, a fresh air baffle 704, a fresh air inlet chamber 706, and a base 708. The fresh air duct is not shown in the diagram. When the air conditioner's drying mode is activated, the rotary valve 504 rotates to the second position 602, and the fresh air baffle 704 rotates to close the upper part of the fresh air inlet chamber 706, reducing its volume. This creates a channel between the air conditioner's interior and the outside. With the air conditioner's air guide closed and the fan on, to prevent the high-humidity air generated during evaporator drying from returning to the room via the fresh air inlet chamber 706, the fresh air duct can be used in reverse for drying and dehumidification. This allows the high-humidity air generated inside the unit to enter the fresh air duct through the exhaust duct 502 and quickly exit to the outside through the fresh air connector 702. Therefore, by using the closed air deflector to achieve the drying function, the evaporated water vapor can be prevented from remaining in the indoor unit casing. This would prevent the air conditioner from becoming unstable due to the inability to release internal pressure in time, thus preventing the air conditioner from shutting down for protection. This improves the reliability of the air conditioner and enhances the user experience.

[0082] Based on the above, such as Figure 8 As shown, an air conditioning control method is provided, which is applied to... Figure 1Taking the target control module 104 as an example, it may include the following steps:

[0083] S802 acquires the real-time internal pipe temperature of the air conditioner when the air conditioner's drying mode is activated.

[0084] Specifically, in combination Figure 3 After the air conditioner is in cooling mode, when the indoor unit data acquisition module 104 receives the user's instruction to turn on the drying mode, it can obtain the real-time indoor pipe temperature through the temperature sensor. In other words, the real-time indoor pipe temperature is the temperature on the heat exchanger of the indoor unit of the air conditioner collected by the temperature sensor at the current moment.

[0085] The indoor unit data acquisition module 104 acquires the user's command to start the drying mode, and the indoor unit drying module 2021 controls the rotary valve 504 to rotate to... Figure 6 In the second position shown in 602, the fresh air baffle 704 can close the fresh air inlet cavity 706, reducing the volume of the fresh air inlet cavity 706. At this time, the indoor unit cavity is connected to the outdoor unit but not to the indoor unit. The air conditioner interior and the outdoor unit form a channel. Thus, when the indoor unit drying module controls the air guide plate to close and the motor to start to achieve the drying function, the water vapor in the air inside the unit can be discharged to the outdoor unit.

[0086] S804 obtains the frequency correction value of the air conditioner compressor based on the current temperature difference between the real-time inner pipe temperature and the target inner pipe temperature.

[0087] In this embodiment, when the air conditioner's drying mode is activated, the indoor ambient temperature is acquired, and the target inner pipe temperature is obtained based on this temperature. Specifically, the target inner pipe temperature is the sum of the indoor ambient temperature and the inner pipe temperature setpoint, which can be any value within the inner pipe temperature range. In this embodiment, the upper limit of the inner pipe temperature range can be 35°C, and the lower limit can be 25°C. The maximum value of the target inner pipe temperature does not exceed 60°C.

[0088] In this embodiment, the real-time inner tube temperature is the inner tube temperature collected at the current moment, and the target inner tube temperature is obtained based on the indoor ambient temperature collected at the current moment. The difference between the two is the current temperature difference value. It is understood that the real-time inner tube temperature and the target inner tube temperature are different at different times. For example, if the indoor ambient temperature is the same at adjacent moments, the target inner tube temperature will be different if different inner tube temperature settings are used.

[0089] In this embodiment, the target control module can be implemented in various ways. Based on the current temperature difference between the real-time inner pipe temperature and the target inner pipe temperature, the frequency correction value of the air conditioner compressor is obtained. As long as the operating frequency of the compressor is adjusted based on the frequency correction value, the real-time inner pipe temperature of the air conditioner will be close to the target inner pipe temperature.

[0090] In one embodiment, the frequency correction value of the air conditioner compressor can be obtained based on a preset algorithm and the current temperature difference between the real-time inner pipe temperature and the target inner pipe temperature. The preset control method may include a PID algorithm or other types of control algorithms.

[0091] S806 adjusts the compressor's operating frequency according to the frequency correction value, and controls the air conditioner to exit the drying mode when it is determined that the air conditioner meets the drying stop conditions.

[0092] In this embodiment, combined with Figure 3 The outdoor unit drying mode control module 2041 can obtain the target operating frequency based on the frequency correction value and the compressor's current operating frequency, thereby controlling the compressor to operate at the target operating frequency.

[0093] In this embodiment, the drying stop condition is used to represent the stopping condition of the air conditioner's drying mode; in other words, the drying stop condition refers to the condition under which the air conditioner exits the drying mode. In one embodiment, the drying stop condition may include at least one of the following: the indoor ambient temperature is greater than or equal to an environmental threshold, or the difference between the indoor inner pipe temperature and the target inner pipe temperature is less than or equal to a threshold.

[0094] In summary, based on Figure 8 The method described herein, when the air conditioner's drying mode is activated, obtains the real-time internal pipe temperature and, based on the current temperature difference between the real-time internal pipe temperature and the target internal pipe temperature, calculates a frequency correction value for the air conditioner's compressor. This means that the influence of the compressor's operating frequency on the drying process is considered when the air conditioner's drying mode is activated. Furthermore, the compressor's operating frequency is adjusted according to the frequency correction value. When the air conditioner meets the drying stop conditions, it exits the drying mode, allowing for accurate control of the air conditioner's drying process and improving the accuracy of drying control. Moreover, the method provided in this application can precisely control the air conditioner's drying process using internal pipe temperature in low-cost air conditioner models without humidity sensors, further improving the accuracy of air conditioner drying control.

[0095] In one embodiment, such as Figure 9 The diagram illustrates a process for obtaining the compressor frequency correction value of an air conditioner based on the current temperature difference between the real-time inner pipe temperature and the target inner pipe temperature. This method is then applied to… Figure 1 Taking the target control module 104 as an example, it may include the following steps:

[0096] S902, obtain the preset target temperature difference value.

[0097] In this embodiment, the preset target temperature difference value is the temperature difference value at a historical time. Specifically, the historical time refers to the temperature difference value at least one time before the current time. The temperature difference value is the difference between the real-time inner tube temperature collected at the corresponding time and the target inner tube temperature.

[0098] S904 uses a preset target temperature difference as the control target and the current temperature difference as the input, and employs a PID algorithm to calculate the frequency correction value.

[0099] The PID algorithm refers to a PID controller (also known as a PID regulator) that controls process flow by proportional (P), integral (I), and derivative (D) of the deviation. The PID controller is one of the most widely used automatic controllers. In this embodiment, with a preset target temperature difference as the control target and the current temperature difference as the input, when calculating the frequency correction value using the PID algorithm, the influence of the compressor's operating frequency on the inner pipe temperature can be reflected by correlating the temperature difference values ​​at adjacent times. Since the inner pipe temperature is directly related to the drying process of the air conditioner's drying mode, the control accuracy of the air conditioner's drying process can be improved.

[0100] In summary, based on Figure 9 The method shown uses a preset target temperature difference as the control target and the current temperature difference as the input. It employs a PID algorithm to calculate the frequency correction value, thereby continuously adjusting the current temperature difference value to approach the preset target temperature difference value by controlling the compressor's operating frequency. The current temperature difference value is then stabilized near the preset target temperature difference value, thus achieving precise control of the current temperature difference value. This allows the real-time inner pipe temperature to approach the target inner pipe temperature, improving the accuracy of the air conditioner's drying control.

[0101] The frequency correction value can be calculated using the PID algorithm in various ways, as long as the compressor's operating frequency can be adjusted to make the real-time inner pipe temperature of the air conditioner approach the target inner pipe temperature.

[0102] In one embodiment, the frequency correction value is calculated using the PID algorithm according to the following formula: △F=Kp(△T(t)-△T(t-1))+Ki△T(t)+Kd(△T(t)-2△T(t-1)+△T(t-2)). Where △F represents the frequency correction value, Kp represents the proportional coefficient, Ki represents the integral coefficient, and Kd represents the derivative coefficient; △T(t) represents the current temperature difference at the current moment, △T(t-1) represents the temperature difference at the previous moment, and △T(t-2) represents the temperature difference between the two moments before the current moment. The temperature difference is the difference between the real-time inner tube temperature and the target inner tube temperature at the corresponding moment; the preset target temperature difference includes the temperature difference between the previous moment and the two moments before the current moment.

[0103] Therefore, the frequency correction value is calculated using the above formula, and the compressor's operating frequency is adjusted according to this value. When the air conditioner meets the drying stop conditions, the air conditioner is controlled to exit the drying mode. The temperature of the inner pipe during drying is controlled by the PID algorithm, thereby achieving efficient and reliable dehumidification, improving the practicality of the air conditioner's drying function, and enhancing the user experience.

[0104] This allows for continuous adjustment of the current temperature difference to approach the preset target temperature difference, and stable adjustment around the preset target temperature difference, achieving precise control of the current temperature difference. This enables the real-time inner tube temperature to approach the target inner tube temperature, improving the accuracy of air conditioning drying control.

[0105] The target control module can be implemented in various ways. It adjusts the air conditioner's operating parameters according to the frequency correction value. When it is determined that the air conditioner meets the drying stop conditions, it controls the air conditioner to exit the drying mode. As long as the drying process of the air conditioner can be accurately controlled according to the frequency correction value, it will be fine.

[0106] In one embodiment, such as Figure 10 The diagram illustrates a process for adjusting the compressor's operating frequency based on a frequency correction value, and controlling the air conditioner to exit the drying mode when the drying stop condition is met. The process may include the following steps:

[0107] S1002, obtain the reference inner pipe temperature of the air conditioner.

[0108] In this embodiment, the reference inner tube temperature is used to represent the temperature of the air conditioner indoor unit heat exchanger after adjusting the compressor's operating frequency according to the frequency correction value. Specifically, the reference inner tube temperature can be obtained by collecting the temperature of the air conditioner indoor unit heat exchanger through a temperature sensing bulb on the heat exchanger.

[0109] S1004: When the difference between the reference inner tube temperature and the target inner tube temperature is within the preset range and the duration is greater than or equal to the target drying time, the air conditioner is determined to meet the drying stop condition, and the air conditioner is controlled to exit the drying mode.

[0110] In this embodiment, when the difference between the reference inner tube temperature and the target inner tube temperature is any value between the lower limit and the upper limit of a preset range, the difference between the reference inner tube temperature and the target inner tube temperature is determined to be within the preset range. In this embodiment, the lower limit of the preset range can be 0.5℃, and the upper limit can be 2℃.

[0111] In this embodiment, the duration is used to represent the length of time the difference between the reference inner tube temperature and the target inner tube temperature remains within a preset range. The target drying time is determined based on the air conditioner's cooling time, which refers to the duration the air conditioner operates in cooling mode before activating the drying mode.

[0112] In summary, based on Figure 10 The method shown obtains the reference inner pipe temperature of the air conditioner, and when the difference between the reference inner pipe temperature and the target inner pipe temperature is within a preset range and the duration is greater than or equal to the target drying time, it determines that the air conditioner meets the drying stop condition and controls the air conditioner to exit the drying mode. Thus, considering the inner pipe temperature of the air conditioner, it accurately controls the execution process of the drying mode, improving the accuracy of the drying control of the air conditioner.

[0113] The target control module can obtain the target drying time in various possible ways, as long as it can accurately control the drying process of the air conditioner based on the target drying time.

[0114] In one embodiment, such as Figure 11 The diagram illustrates a method for obtaining the target drying time, which may include the following steps:

[0115] S1102, obtain the target cooling time of the air conditioner.

[0116] In this embodiment, the target cooling duration of the air conditioner is the average cooling duration over multiple cycles. The cycle refers to the period during which the air conditioner operates in cooling mode before activating the drying mode. Specifically, the cooling duration corresponding to multiple cycles of air conditioner operation in cooling mode can be recorded using a timer, and the target cooling duration can be obtained based on the cooling duration corresponding to multiple cycles.

[0117] S1104, based on the target cooling time range in which the target cooling time falls, obtain the target drying time.

[0118] In this embodiment, multiple cooling duration ranges can be preset. For example, the multiple cooling duration ranges may include: a first cooling duration range, a second cooling duration range, a third cooling duration range, a fourth cooling duration range, a fifth cooling duration range, and a sixth cooling duration range.

[0119] The upper limit of the first cooling time range is the same as the lower limit of the second cooling time range, but the first cooling time range does not include the upper limit of the first cooling time range; the upper limit of the second cooling time range is the same as the lower limit of the third cooling time range, but the second cooling time range does not include the upper limit of the second cooling time range, and so on. In the sixth cooling time range, only the lower limit is set, and no upper limit is set.

[0120] Specifically, in this embodiment, the lower limit of the first cooling duration range can be 0, and the upper limit can be 20, so the first cooling duration range is represented as [0, 20). The lower limit of the second cooling duration range can be 20, and the upper limit can be 40, so the second cooling duration range is represented as [20, 40]. The lower limit of the third cooling duration range can be 40, and the upper limit can be 60, so the third cooling duration range is represented as [40, 60]. The lower limit of the fourth cooling duration range can be 60, and the upper limit can be 90, so the fourth cooling duration range is represented as [60, 90]. The lower limit of the fifth cooling duration range can be 90, and the upper limit can be 120, so the fifth cooling duration range is represented as [90, 120]. The lower limit of the sixth cooling duration range can be 120, so the sixth cooling duration range is represented as [120, ∞). The unit of cooling duration is minutes (min).

[0121] Specifically, the target cooling time can be compared with various cooling time ranges to obtain the target cooling time range in which the target cooling time falls. For example, if the target cooling time is 75 minutes, and 75 minutes falls within the fourth cooling time range, then the target cooling time range is determined to be the fourth cooling time range.

[0122] In one embodiment, obtaining the target drying time based on the target cooling time range includes: obtaining a mapping relationship between the cooling time range and the drying time, and obtaining the target drying time that matches the target cooling time range based on the mapping relationship.

[0123] In summary, based on Figure 11 The method shown can obtain the target drying time. When the difference between the reference inner pipe temperature and the target inner pipe temperature of the air conditioner is within the preset range and the duration is greater than or equal to the target drying time, it is determined that the air conditioner meets the drying stop condition. The air conditioner can then be controlled to exit the drying mode. Thus, considering the inner pipe temperature of the air conditioner, the execution process of the drying mode can be accurately controlled, improving the accuracy of the drying control of the air conditioner.

[0124] The target control module can obtain the target drying time by various possible methods based on the target cooling time range. As long as the air conditioner's drying process can be accurately controlled based on the target drying time, it is sufficient.

[0125] In one embodiment, such as Figure 12 As shown, a flowchart illustrating the process of obtaining a target drying time based on the target cooling time range within which the target cooling time falls is provided. The flowchart may include the following steps:

[0126] S1202, obtain the target average temperature of the difference between historical indoor ambient temperature and historical inner pipe temperature.

[0127] In this embodiment, the target cooling duration of the air conditioner is the average cooling duration over multiple cycles. The historical indoor ambient temperature refers to the average indoor ambient temperature over multiple cycles, and the historical inner pipe temperature refers to the average inner pipe temperature over multiple cycles. The difference between the historical indoor ambient temperature and the historical inner pipe temperature can be obtained, and the target average temperature can be obtained by averaging the difference.

[0128] S1204. The target dryness coefficient is obtained based on the target average temperature, the target cooling time range, and the preset coefficient table. The preset coefficient table includes multiple average temperature ranges, multiple cooling time ranges, and multiple dryness coefficients. Each average temperature range has a corresponding cooling time range and dryness coefficient.

[0129] Specifically, based on a preset coefficient table, a target average temperature range matching the target average temperature can be determined from multiple average temperature ranges. Then, based on the target average temperature range and the target cooling time range, the target drying coefficient can be determined.

[0130] Based on the content of S1104, as shown in Table 1, a preset coefficient table is provided. The contents of Table 1 are as follows:

[0131] Table 1

[0132]

[0133] Table 1 includes six cooling duration ranges: [0,20), [20,40), [40,60), [60,90), [90,120), and [120,∞). It also includes five average temperature ranges: [0,2), [2,3), [3,4), [4,5), and [5,∞). Each average temperature range corresponds to a cooling duration range and a drying coefficient. For example, based on Table 1, if the target average temperature is 2.4℃, the target average temperature range is [2,3), the target cooling duration range is [60,90), and the target drying coefficient is 0.9.

[0134] S1206, based on the target drying coefficient, obtain the target drying time.

[0135] Specifically, the target drying time is the product of the target drying coefficient and the drying threshold. The drying threshold is determined according to the indoor unit model of the air conditioner. In this embodiment, the drying threshold is any value between 10 minutes and 20 minutes.

[0136] In summary, based on Figure 12The method described above obtains the target average temperature, which is the difference between historical indoor ambient temperature and historical inner pipe temperature. Based on the target average temperature, the target cooling duration range, and a preset coefficient table, a target drying coefficient can be obtained, and the target drying duration can be derived from the target drying coefficient. Therefore, when the difference between the air conditioner's reference inner pipe temperature and the target inner pipe temperature is within the preset range and the duration is greater than or equal to the target drying duration, the air conditioner meets the drying stop condition and can be controlled to exit the drying mode. This allows for accurate control of the drying mode execution process while considering the air conditioner's inner pipe temperature, improving the accuracy of air conditioner drying control.

[0137] In conjunction with the above, in one embodiment, such as Figure 13 As shown, an air conditioning control method is provided, which may include the following steps:

[0138] S1302: When the air conditioner's drying mode is activated, the real-time temperature of the air conditioner's internal pipes is obtained.

[0139] S1304, obtain the preset target temperature difference value.

[0140] S1306 uses a preset target temperature difference as the control target and the current temperature difference as the input, and employs a PID algorithm to calculate the frequency correction value.

[0141] Specifically, the frequency correction value is calculated using the PID algorithm according to the following formula:

[0142] △F=Kp(△T(t)-△T(t-1))+Ki△T(t)+Kd(△T(t)-2△T(t-1)+△T(t-2));

[0143] Wherein, △F represents the frequency correction value, Kp represents the proportional coefficient, Ki represents the integral coefficient, and Kd represents the differential coefficient; △T(t) represents the current temperature difference value at the current moment, △T(t-1) represents the temperature difference value at the previous moment, and △T(t-2) represents the temperature difference value at the two moments before the current moment. The temperature difference value is the difference between the real-time inner tube temperature and the target inner tube temperature at the corresponding moment; wherein, the preset target temperature difference value includes the temperature difference value at the previous moment and the temperature difference value at the two moments before the current moment.

[0144] S1308, obtain the target cooling time of the air conditioner.

[0146] S1312, obtain the target dryness coefficient based on the target average temperature, the target cooling time range and the preset coefficient table; the preset coefficient table includes multiple average temperature ranges, multiple cooling time ranges and multiple dryness coefficients, and each average temperature range has a corresponding cooling time range and dryness coefficient.

[0147] S1314, based on the target drying coefficient, obtain the target drying time.

[0148] S1316, obtain the reference inner pipe temperature of the air conditioner.

[0149] S1318, when the difference between the reference inner tube temperature and the target inner tube temperature is within the preset range and the duration is greater than or equal to the target drying time, the air conditioner is determined to meet the drying stop condition, and the air conditioner is controlled to exit the drying mode.
