Description

TECHNICAL FIELD

[0001] The present application relates to, but is not limited to, the technical field of air conditioner control, and in particular to an air conditioner-based self-cleaning control method and device, an air conditioner, and a medium. BACKGROUND

[0002] The self-cleaning process of a conventional air conditioner is performed in a fixed period, with the use time of the air conditioner exceeding a preset time threshold as a triggering condition. However, such a self-cleaning method cannot be dynamically adjusted in real time according to the actual pollution level of the air conditioner, which may easily lead to energy waste or incomplete cleaning of the air conditioner. SUMMARY

[0003] The present application provides an air conditioner-based self-cleaning control method and device, an air conditioner, and a medium, which can effectively improve the cleanliness of the air conditioner while reducing energy waste.

[0004] In a first aspect, an air conditioner-based self-cleaning control method is provided, which is applied to an air conditioner. The air conditioner includes an evaporator, and a water tray is arranged below the evaporator. A turbidity sensor is arranged in the water tray. The method includes the following steps.

[0005] When it is detected that the air conditioner is started, the turbidity value of the turbidity sensor is detected and recorded in real time.

[0006] When the turbidity value is greater than a second threshold value, a self-cleaning reminder information is generated based on the turbidity value, and the self-cleaning reminder information is sent to a remote control device associated with the air conditioner.

[0007] When a self-cleaning instruction of the remote control device is responded to, the air conditioner is controlled to enter a self-cleaning mode.

[0008] In some embodiments, the self-cleaning mode includes a condensation mode, a frosting mode, a defrosting mode, and a high-temperature sterilization mode. Controlling the air conditioner to enter the self-cleaning mode includes the following steps.

[0009] When it is determined that the air conditioner starts the self-cleaning mode, the air conditioner is controlled to start the condensation mode, the frosting mode, and the defrosting mode in sequence, and then the current turbidity value is detected.

[0010] When the current turbidity value is greater than the second threshold value, the air conditioner is controlled to restart the condensation mode, the frosting mode, and the defrosting mode until the current turbidity value is less than or equal to the second threshold value, and then the air conditioner is controlled to start the high-temperature sterilization mode.

[0011] In some embodiments, when the current turbidity value is greater than the second threshold, the air conditioner is controlled to restart the condensation mode, the frosting mode, and the defrosting mode until the current turbidity value is less than or equal to the second threshold, at which point the air conditioner is controlled to start the high-temperature sterilization mode, including:

[0012] Determine the reference duration for each of the following modes: condensation mode, frosting mode, and defrosting mode, in which the air conditioner was last activated.

[0013] When the current turbidity value is greater than the second threshold, the first target duration corresponding to the next activation of the condensation mode, the frosting mode and the defrosting mode is calculated based on each of the reference durations and the target ratio values, wherein each of the first target durations is less than the corresponding reference duration;

[0014] The air conditioner is controlled to sequentially activate the condensation mode, the frosting mode, and the defrosting mode for each of the first target durations until the current turbidity value is less than or equal to the second threshold. Then, the air conditioner is controlled to activate the high-temperature sterilization mode. The target ratio value associated with the first target duration for each activation of a mode other than the high-temperature sterilization mode decreases as the number of cycles of the condensation mode, the frosting mode, and the defrosting mode increases.

[0015] In some embodiments, after controlling the air conditioner to enter a self-cleaning mode in response to a self-cleaning command from the remote control device, the method further includes:

[0016] Determine the reference turbidity value of the air conditioner before the last activation of the self-cleaning mode;

[0017] If the current turbidity value is greater than the second threshold and the current turbidity value is greater than the reference turbidity value, the reference duration is linearly adjusted upward based on the current turbidity value and the reference turbidity value to obtain the second target duration, and the air conditioner is controlled to enter the next self-cleaning mode. The first start duration of the condensation mode, the frosting mode and the defrosting mode corresponding to the next self-cleaning mode are the corresponding second target durations, and each second target duration is greater than the corresponding reference duration.

[0018] When the current turbidity value is greater than the second threshold and the current turbidity value is less than or equal to the reference turbidity value, the air conditioner is controlled to enter the next self-cleaning mode, wherein the first start-up time of the condensation mode, the frosting mode and the defrosting mode corresponding to the next self-cleaning mode are respectively the corresponding reference time.

[0019] In some embodiments, the air conditioner further includes a sterilization module and a fan. The air conditioner also includes a sterilization module. After the air conditioner is controlled to enter a self-cleaning mode in response to a self-cleaning command from the remote control device, the method further includes:

[0020] The fan is started simultaneously with the activation of the condensation mode;

[0021] After activating the frosting mode, the fan is turned off, and the frosting duration and the current inner tube temperature of the evaporator are determined.

[0022] When the frosting duration reaches a first duration and the current inner tube temperature is less than a preset temperature threshold, the sterilization module is activated, wherein the first duration is the product of the frosting duration and a first ratio value.

[0023] When the air conditioner enters the next self-cleaning mode, if the current frosting duration reaches the second duration and the current inner pipe temperature is less than the preset temperature threshold, the sterilization module is activated, wherein the first duration is the product of the frosting duration and the second ratio value, and the second ratio value is less than the first ratio value.

[0024] In some embodiments, the remote control device has a corresponding display interface. When the turbidity value is greater than a second threshold, a self-cleaning reminder message is generated based on the turbidity value, and the self-cleaning reminder message is sent to the remote control device, including:

[0025] When the turbidity value is less than or equal to a first threshold, or greater than the first threshold and less than or equal to a second threshold, the current turbidity value is displayed on the display interface. Here, the current turbidity value being less than or equal to the first threshold indicates that the cleanliness of the air conditioner is excellent; the current turbidity value being greater than the first threshold and less than or equal to the second threshold indicates that the cleanliness of the air conditioner is good; and the current turbidity value being greater than the second threshold and less than the third threshold indicates that the cleanliness of the air conditioner is medium.

[0026] When the turbidity value is greater than the second threshold, a self-cleaning reminder message is generated based on the turbidity value, and the self-cleaning reminder message is sent to the remote control device;

[0027] When the turbidity value is greater than the third threshold, a self-cleaning reminder message is generated based on the turbidity value, the self-cleaning reminder message is sent to the remote control device, and the number of times the self-cleaning mode of the air conditioner is started and the number of times the reminder message is sent are recorded. The current turbidity value being greater than the third threshold indicates that the cleanliness of the air conditioner is of a poor level.

[0028] In some embodiments, after recording the number of times the self-cleaning mode of the air conditioner is activated, the method further includes:

[0029] When the number of startups is 0 and the number of transmissions is greater than a preset threshold, a target time period is determined, wherein the target time period is located in the time period corresponding to the minimum number of startups of the air conditioner, and the air conditioner is not started;

[0030] The air conditioner is controlled to enter the self-cleaning mode during the target time period.

[0031] Secondly, embodiments of this application provide a control device, including at least one control processor and a memory for communicatively connecting to the at least one control processor; the memory stores instructions executable by the at least one control processor, which, when executed by the at least one control processor, enable the at least one control processor to perform the self-cleaning control method based on an air conditioner as described in the first aspect.

[0032] Thirdly, embodiments of this application also provide an air conditioner, including the control device of the second aspect.

[0033] Fourthly, embodiments of this application also provide a computer-readable storage medium storing computer-executable instructions for performing the self-cleaning control method based on an air conditioner as described in the first aspect.

[0034] This application provides a self-cleaning control method, device, air conditioner, and medium based on an air conditioner. The method includes: when the air conditioner is detected to be running, detecting and recording the turbidity value of a turbidity sensor in real time; when the turbidity value is greater than a second threshold, generating a self-cleaning reminder message based on the turbidity value and sending the self-cleaning reminder message to a remote control device associated with the air conditioner; and controlling the air conditioner to enter a self-cleaning mode in response to a self-cleaning command from the remote control device. According to the solution provided in this application, turbidity value is used as the core indicator for judging the cleanliness level inside the air conditioner. When the turbidity value does not meet the requirements, a reminder message is generated and sent to the remote control device, and the air conditioner is controlled to enter a self-cleaning mode in response to a command from the remote control device. Compared with existing methods that perform air conditioner self-cleaning within a fixed period, this method can dynamically adjust in real time according to the actual pollution level of the air conditioner, effectively improving the cleanliness of the air conditioner while reducing energy waste. Attached Figure Description

[0035] Figure 1 This is a flowchart of the steps of a self-cleaning control method based on an air conditioner provided in one embodiment of this application;

[0036] Figure 2This is a structural diagram of a control device provided in another embodiment of this application. Detailed Implementation

[0037] 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.

[0038] It is understandable that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] Traditional air conditioners' self-cleaning process is performed within a fixed cycle, triggered by the air conditioner's usage time exceeding a preset threshold. However, this self-cleaning method cannot dynamically adjust in real time according to the actual degree of pollution in the air conditioner, which can easily lead to energy waste or incomplete cleaning.

[0040] To address the aforementioned problems, this application provides a self-cleaning control method, device, air conditioner, and medium based on an air conditioner. The method includes: when the air conditioner is detected to be running, detecting and recording the turbidity value of a turbidity sensor in real time; when the turbidity value exceeds a first threshold, generating a self-cleaning reminder message based on the turbidity value and sending the self-cleaning reminder message to a remote control device associated with the air conditioner; and controlling the air conditioner to enter a self-cleaning mode in response to a self-cleaning command from the remote control device. According to the solution provided in this application, turbidity value is used as the core indicator for judging the cleanliness level inside the air conditioner. When the turbidity value does not meet the requirements, a reminder message is generated and sent to the remote control device, and the air conditioner is controlled to enter a self-cleaning mode in response to a command from the remote control device. Compared to existing methods that perform air conditioner self-cleaning within a fixed cycle, this method can dynamically adjust the air conditioner in real time according to the actual degree of contamination, effectively improving the cleanliness of the air conditioner while reducing energy waste.

[0041] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0042] refer to Figure 1 , Figure 1This is a flowchart illustrating the steps of a self-cleaning control method for an air conditioner according to an embodiment of this application. This application provides a self-cleaning control method for an air conditioner, which includes an evaporator and a water collection tray below the evaporator. A turbidity sensor is installed in the water collection tray. The method includes, but is not limited to, the following steps:

[0043] Step S10: When the air conditioner is detected to be running, the turbidity value of the turbidity sensor is detected and recorded in real time.

[0044] It is understandable that after the air conditioner starts cooling, water vapor in the internal pipes of the air conditioner condenses on the surface of the evaporator, producing condensate. The condensate flows into the drip tray. Therefore, by detecting the turbidity value of the condensate in the drip tray, it can be used as an indicator of the cleanliness of the air conditioner.

[0045] Step S20: When the turbidity value is greater than the second threshold, a self-cleaning reminder message is generated based on the turbidity value, and the self-cleaning reminder message is sent to the remote control device associated with the air conditioner.

[0046] Specifically, in some embodiments, the remote control device has a corresponding display interface. Figure 1 Step S20 includes, but is not limited to, the following steps:

[0047] Step S21: When the turbidity value is less than or equal to the first threshold, or greater than the first threshold and less than or equal to the second threshold, the current turbidity value is displayed on the display interface. Here, the current turbidity value being less than or equal to the first threshold indicates that the cleanliness of the air conditioner is excellent; the current turbidity value being greater than the first threshold and less than or equal to the second threshold indicates that the cleanliness of the air conditioner is good; and the current turbidity value being greater than the second threshold and less than the third threshold indicates that the cleanliness of the air conditioner is medium.

[0048] Step S22: When the turbidity value is greater than the second threshold, a self-cleaning reminder message is generated based on the turbidity value and sent to the remote control device;

[0049] Step S23: When the turbidity value is greater than the third threshold, a self-cleaning reminder message is generated based on the turbidity value, the self-cleaning reminder message is sent to the remote control device, and the number of times the air conditioner's self-cleaning mode is started and the number of times the reminder message is sent are recorded. The current turbidity value being greater than the third threshold indicates that the cleanliness of the air conditioner is of a poor level.

[0050] It is understood that in this embodiment, turbidity values ​​in different ranges represent different cleanliness levels of the air conditioner. Specifically, they are associated by a turbidity value-cleanliness mapping table. Based on this mapping table, an effective data basis is provided for determining whether to generate a self-cleaning reminder, or, after entering the self-cleaning mode, it serves as the basis for determining whether to enter the high-temperature sterilization mode.

[0051] Specifically, the turbidity value-cleanliness mapping table of this embodiment is shown in Table 1:

[0052] Table 1. Turbidity Value-Cleanliness Mapping Table

[0053]

[0054] Specifically, referring to Table 1 above, in this embodiment, the first threshold corresponds to A1, the second threshold corresponds to A2, and the third threshold corresponds to A3. When the turbidity value is less than or equal to the first threshold (i.e., belonging to [0, A1]), the cleanliness level of the current air conditioner is determined to be excellent, indicating that there are very few pollutants inside the air conditioner. When the turbidity value is greater than the first threshold and less than or equal to the second threshold (i.e., belonging to (A1, A2]), the cleanliness level of the current air conditioner is determined to be good, indicating that there are a small amount of pollutants inside the air conditioner. When the turbidity value is greater than the second threshold and less than or equal to the third threshold (i.e., belonging to (A2, A3]), the cleanliness level of the current air conditioner is determined to be medium, indicating that there are a certain amount of pollutants inside the air conditioner. When the turbidity value is greater than the third threshold, the cleanliness level of the current air conditioner is determined to be poor, indicating that there are many pollutants inside the air conditioner.

[0055] In addition, in some embodiments, after performing step S23, the self-cleaning control method based on the air conditioner in this application embodiment also includes, but is not limited to, the following steps:

[0056] Step S231: When the number of startups is 0 and the number of transmissions is greater than a preset threshold, determine the target time period, wherein the target time period is the time period corresponding to the minimum number of air conditioner startups;

[0057] Step S232: Control the air conditioner to enter self-cleaning mode during the target time period.

[0058] It is understood that this embodiment uses a medium level of cleanliness as the warning trigger condition. When the cleanliness is in the "excellent" or "good" range, no user is not notified; the current cleanliness status of the air conditioner is only displayed on the display interface corresponding to the remote control device. Only when the cleanliness is below the "medium" level will the user be reminded on the air conditioner display panel that the air conditioner needs cleaning (the user can also cancel the display via the remote control or APP). The user can manually control the air conditioner or use the APP to activate the self-cleaning mode, or schedule automatic cleaning. When the cleanliness detection consistently shows a "poor" level, the user is reminded to enter the self-cleaning mode each time the air conditioner is turned on. The number of times the air conditioner activates the self-cleaning mode and the number of reminder messages sent when the cleanliness is at the poor level are recorded. When the number of activations is 0 and the number of messages sent is greater than a preset threshold (those skilled in the art can determine the threshold based on actual needs; in this embodiment, the threshold is set to 3), the air conditioner is directly controlled to enter the self-cleaning mode during a target time period. In this embodiment, the target time period is selected from the time period when the user's historical air conditioner usage habits are the least, and the user is not currently using the air conditioner. This self-cleaning control mechanism, combined with tiered reminders, user control, and intelligent enforcement, transforms passive response into proactive health management, effectively ensuring the cleanliness of the air conditioner while enhancing the user experience.

[0059] Step S30: In response to the self-cleaning command from the remote control device, control the air conditioner to enter the self-cleaning mode.

[0060] It is understood that, referring to the description of the above embodiments, the self-cleaning instruction in this embodiment may be passively triggered after the user receives the reminder information, or it may be forcibly triggered by the system based on the situation in steps S231 to S232, when it is determined that the user has not responded to the self-cleaning reminder information for a long time.

[0061] In addition, the execution subject (i.e., the air conditioner) corresponding to the self-cleaning control method based on the air conditioner in this embodiment is an energy-saving refrigeration device.

[0062] Specifically, in some embodiments, the self-cleaning mode includes a condensation mode, a frosting mode, a defrosting mode, and a high-temperature sterilization mode. Figure 1 Step S30 includes, but is not limited to, the following steps:

[0063] Step S31: After determining that the air conditioner has started the self-cleaning mode, and controlling the air conditioner to sequentially start the condensation mode, the frosting mode and the defrosting mode, the current turbidity value is detected.

[0064] Step S32: If the current turbidity value is greater than the second threshold, control the air conditioner to restart the condensation mode, frosting mode and defrosting mode until the current turbidity value is less than or equal to the second threshold, and then control the air conditioner to start the high temperature sterilization mode.

[0065] It is understood that the self-cleaning mode of this embodiment includes condensation mode, frosting mode, defrosting mode, and high-temperature sterilization mode. The high-temperature sterilization mode is only effective on a relatively clean surface. Therefore, after triggering the air conditioner to enter self-cleaning mode, this embodiment requires three physical cleaning steps: condensation mode, frosting mode, and defrosting mode. Only after confirming that the current turbidity value reaches a "good" level is the high-temperature sterilization mode activated. A single condensation, frosting, or defrosting cycle may not completely remove heavy contamination (such as long-term uncleaning or oily environments). Therefore, after executing one round of condensation, frosting, or defrosting mode, this embodiment uses turbidity value detection to determine whether the current cleaning effect meets the requirements, deciding whether to repeat the condensation, frosting, or defrosting mode or enter the high-temperature sterilization mode, forming a "cleaning-evaluation-re-cleaning" closed loop. Only when the turbidity value enters the "good" range does it proceed to the next stage (high-temperature sterilization mode), avoiding ineffective sterilization or residual contamination and ensuring the reliability of the self-cleaning mode's cleaning effect.

[0066] Specifically, in some embodiments, the self-cleaning mode includes a condensation mode, a frosting mode, a defrosting mode, and a high-temperature sterilization mode. Figure 1 Step S32 includes, but is not limited to, the following steps:

[0067] Step S321: Determine the reference duration for each of the last activation modes of the air conditioner: condensation mode, frosting mode, and defrosting mode.

[0068] Step S322: When the current turbidity value is greater than the second threshold, calculate the first target duration corresponding to the next activation of the condensation mode, frosting mode and defrosting mode based on each reference duration and target ratio value, wherein each first target duration is less than the corresponding reference duration.

[0069] Step S323: Control the air conditioner to sequentially start the condensation mode, frosting mode and defrosting mode for each first target duration until the current turbidity value is less than or equal to the second threshold. Then control the air conditioner to start the high temperature sterilization mode. The target ratio value associated with the first target duration of each mode other than the high temperature sterilization mode decreases as the number of cycles of the condensation mode, frosting mode and defrosting mode increases.

[0070] It is understood that the target ratio value in this embodiment decreases as the number of cycles of condensation mode, frosting mode, and defrosting mode increases. For example, after the air conditioner enters the self-cleaning mode, the reference time for starting the condensation mode is t1, the reference time for starting the frosting mode is t2, and the reference time for starting the defrosting mode is t3. After the defrosting mode ends, if the current turbidity value is detected to be greater than the second threshold, the condensation mode, frosting mode, and defrosting mode need to be cycled a second time, and the time taken is (0.5t1, 0.5t2, 0.5t3). If the turbidity value detected after the second cycle is greater than the second threshold, the condensation mode, frosting mode, and defrosting mode are cycled a third time, and the time taken is (0.4t1, 0.4t2, 0.4t3), until the turbidity value detected after a certain cycle is less than or equal to the second threshold, and the air conditioner is controlled to start the high-temperature sterilization mode.

[0071] In addition, in some embodiments, after performing step S30, the self-cleaning control method based on the air conditioner of this application embodiment also includes, but is not limited to, the following steps:

[0072] Step S41: Determine the reference turbidity value of the air conditioner before the last time the self-cleaning mode was started;

[0073] Step S42: When the current turbidity value is greater than the second threshold and the current turbidity value is greater than the reference turbidity value, the reference duration is linearly adjusted upward based on the current turbidity value and the reference turbidity value to obtain the second target duration, and the air conditioner is controlled to enter the next self-cleaning mode. The first start duration of the condensation mode, frosting mode and defrosting mode corresponding to the next self-cleaning mode are the corresponding second target durations, and each second target duration is greater than the corresponding reference duration.

[0074] Step S43: If the current turbidity value is greater than the second threshold and the current turbidity value is less than or equal to the reference turbidity value, control the air conditioner to enter the next self-cleaning mode. The initial start-up time of the condensation mode, frosting mode and defrosting mode corresponding to the next self-cleaning mode are the corresponding reference times.

[0075] It is understandable that, in this embodiment, after entering the self-cleaning mode again, the start-up time of each intermediate mode (i.e., condensation mode, frosting mode, and defrosting mode) other than the high-temperature sterilization mode is determined based on the start-up time of each intermediate mode in the previous self-cleaning mode and the reference turbidity value of the air conditioner before the last start of the self-cleaning mode. Specifically, the following two situations are involved: (1) When the current turbidity value is greater than the second threshold and the current turbidity value is greater than the reference turbidity value, the reference time is linearly corrected upward based on the current turbidity value and the reference turbidity value to obtain the second target time, and the air conditioner is controlled to enter the next self-cleaning mode. The first start-up time of the condensation mode, frosting mode, and defrosting mode corresponding to the next self-cleaning mode are the corresponding second target times, and the second target time is greater than the corresponding reference time. That is to say, when the air conditioner enters the self-cleaning mode again and the turbidity value is greater than the reference turbidity value after the last self-cleaning mode is executed, the start-up time of the intermediate mode of the current self-cleaning mode needs to be increased. Specifically, the start-up time of the intermediate mode of the previous self-cleaning mode is increased. The reference duration of each intermediate mode of the formula is linearly corrected upward to obtain each second target duration. The second target duration is used as the start duration of each intermediate mode corresponding to the current self-cleaning mode. (2) When the current turbidity value is greater than the second threshold and the current turbidity value is less than or equal to the reference turbidity value, the air conditioner is controlled to enter the next self-cleaning mode. The first start duration of the condensation mode, frosting mode and defrosting mode corresponding to the next self-cleaning mode are the corresponding reference durations. That is to say, when the air conditioner enters the self-cleaning mode again and the turbidity value is less than or equal to the reference turbidity value after the last self-cleaning mode is executed, the reference durations of the last time are retained as the start durations of each intermediate mode corresponding to the current self-cleaning mode.

[0076] In addition, in some embodiments, the air conditioner further includes a sterilization module and a fan. After executing step S30, the self-cleaning control method based on the air conditioner in this application embodiment also includes, but is not limited to, the following steps:

[0077] Step S44: Simultaneously with activating the condensation mode, start the fan;

[0078] Step S45: After starting the frosting mode, turn off the fan and determine the frosting duration and the current inner tube temperature of the evaporator.

[0079] Step S46: When the frosting time reaches the first duration and the current inner tube temperature is less than the preset temperature threshold, the sterilization module is activated, wherein the first duration is the product of the frosting time and the first ratio value.

[0080] Step S47: When the air conditioner enters the next self-cleaning mode, if the current frosting time reaches the second duration and the current internal pipe temperature is less than the preset temperature threshold, the sterilization module is activated. The second duration is the product of the frosting time and the second proportional value, and the second proportional value is less than the first proportional value.

[0081] Specifically, the sterilization module in this embodiment can be a UVC sterilization module or a cold plasma sterilization module, which can be selected by those skilled in the art according to actual needs.

[0082] It is understandable that the sterilization module needs to control the start of the fan and the internal pipe temperature cannot be too low in order to ensure the sterilization effect. Specifically, in this embodiment, when the condensation mode is started, the fan is turned on to adsorb the air in the indoor environment (including humid air and harmful substances in the air). After the fan is turned off, the sterilization module is started again.

[0083] Understandably, in this embodiment, considering that the sterilization module needs to control the start of the fan, and that controlling the evaporator's inner tube temperature to be not too low is more effective, the trigger conditions for starting the sterilization module are set as follows: after entering the self-cleaning mode, the frosting duration of the frosting mode reaches the set duration, and the evaporator's inner tube temperature is lower than a preset temperature threshold. The set duration is determined by the initial frosting duration and the proportional decrease in value as the self-cleaning mode is activated. For example, the initial frosting duration for the first activation of the self-cleaning mode is set as the first duration, and the current corresponding ratio value, i.e., the first ratio value, is 1. At this time, if the trigger condition is detected, the sterilization module is activated. When the air conditioner enters the next self-cleaning mode, such as the second time, the trigger condition for the sterilization module includes the frosting duration reaching the second duration and the current indoor pipe temperature being less than the preset temperature threshold, where the second duration is 1 / 4 of the first duration. When the air conditioner enters the self-cleaning mode for the third time, the trigger condition for the sterilization module includes the frosting duration reaching the third duration and the current indoor pipe temperature being less than the preset temperature threshold, where the third duration is 1 / 5 of the first duration.

[0084] In summary, this embodiment utilizes a turbidity sensor to detect the cleanliness of the air conditioner's self-cleaning function, using wastewater turbidity as a direct indicator. This overcomes the limitations of traditional indirect parameter estimation and enables differentiated dynamic intelligent optimization of the activation time of each intermediate mode (i.e., condensation mode, frosting mode, defrosting mode, and high-temperature sterilization mode) within the self-cleaning system, balancing cleaning effectiveness with energy-saving requirements. Furthermore, by determining the amount of dirt residue through turbidity values, the activation time of each intermediate mode is dynamically adjusted, or multiple cycles of intermediate modes other than the high-temperature sterilization mode are triggered, or the air conditioner is triggered to re-enter the self-cleaning mode. This solves the problem of mismatch between sterilization timing and cleaning status, significantly improving internal cleanliness and reducing energy consumption.
