Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a self-cleaning control method, device, system, and air conditioner based on air conditioning. Background Technology

[0002] Traditional air conditioners defrost periodically at fixed intervals or for extended periods. This fixed defrosting process cannot be dynamically adjusted based on actual frost conditions, even under varying environments. For example, starting the compressor or indoor fan when defrosting is unnecessary wastes energy. Starting the compressor consumes significant electrical energy, and prolonged operation increases power consumption, reducing energy efficiency. Furthermore, the fixed defrosting operation of traditional air conditioners cannot be adjusted according to changes in ambient temperature, failing to meet actual needs under different conditions and significantly reducing the air conditioner's efficiency. Summary of the Invention

[0003] This invention provides a self-cleaning control method, device, system, and air conditioner based on air conditioning, aiming to solve the problem that in the prior art, air conditioners cannot dynamically adjust the defrosting operation according to the ambient temperature, resulting in high energy consumption and reduced air conditioner efficiency.

[0004] In a first aspect, embodiments of the present invention provide a self-cleaning control method based on an air conditioner, comprising:

[0005] The system receives a user's command to enter the air conditioner's self-cleaning mode; wherein the self-cleaning mode sequentially includes a frosting process and a defrosting process.

[0006] The temperature of the inner tube of the air conditioner evaporator and the ambient temperature of the room are obtained after the frosting process.

[0007] Based on the inner tube temperature and the ambient temperature, a first temperature change difference is calculated, and the first temperature change difference is used as the current temperature change difference.

[0008] Defrosting process: Determine whether the current temperature change difference is less than a preset threshold. If so, turn on the air conditioner compressor and turn off the air conditioner indoor fan to perform defrosting operation; if not, turn on the air conditioner compressor and indoor fan at the same time to perform defrosting operation.

[0009] Secondly, embodiments of the present invention provide a self-cleaning control device based on an air conditioner, comprising:

[0010] The mode entry unit is used to receive user instructions to enter the air conditioner's self-cleaning mode; wherein, the self-cleaning mode includes a frosting process and a defrosting process in sequence.

[0011] The data acquisition unit is used to acquire the inner pipe temperature of the air conditioner evaporator and the indoor ambient temperature after the frosting process.

[0012] The data calculation unit is used to calculate a first temperature change difference based on the inner tube temperature and the ambient temperature, and to use the first temperature change difference as the current temperature change difference.

[0013] The defrosting process unit is used to determine whether the current temperature change difference is less than a preset threshold. If so, the air conditioner compressor is turned on while the air conditioner indoor fan is turned off to perform the defrosting operation; if not, the air conditioner compressor and indoor fan are turned on simultaneously to perform the defrosting operation.

[0014] Thirdly, embodiments of the present invention provide an air conditioning system, including a self-cleaning control device based on air conditioning as described in the second aspect.

[0015] Fourthly, embodiments of the present invention provide an air conditioner, wherein the air conditioner stores a computer program, and when the computer program is executed by a processor, it implements the self-cleaning control method based on the air conditioner of the first aspect.

[0016] This invention provides a self-cleaning control method for air conditioners, including entering a self-cleaning mode of the air conditioner. The self-cleaning mode sequentially includes a frosting process and a defrosting process. The method involves acquiring the inner pipe temperature of the air conditioner evaporator and the ambient temperature after the frosting process, calculating a first temperature change difference, and using this first temperature change difference as the current temperature change difference. The defrosting process involves determining whether the current temperature change difference is less than a preset threshold. If so, the air conditioner compressor is turned on while the indoor fan is turned off to perform a defrosting operation. If not, both the air conditioner compressor and the indoor fan are turned on simultaneously to perform the defrosting operation. This invention reduces the energy consumption of the air conditioner and significantly improves its efficiency by dynamically adjusting the switching of the compressor and indoor fan based on the current temperature change value, thereby determining whether the current temperature change value meets a preset threshold.

[0026] Please see below. Figure 1 , Figure 1 The flowchart of a self-cleaning control method based on air conditioning provided in an embodiment of the present invention specifically includes steps S101 to S104.

[0027] S101. Receive user's instruction to enter the air conditioner's self-cleaning mode; wherein, the self-cleaning mode includes a frosting process and a defrosting process in sequence;

[0028] S102. Obtain the inner tube temperature of the air conditioner evaporator and the indoor ambient temperature after the frosting process;

[0029] S103. Calculate the first temperature change difference based on the inner tube temperature and the ambient temperature, and use the first temperature change difference as the current temperature change difference.

[0030] S104. Defrosting process: Determine whether the current temperature change difference is less than a preset threshold. If yes, turn on the air conditioner compressor and turn off the air conditioner indoor fan to perform defrosting operation. If no, turn on the air conditioner compressor and indoor fan at the same time to perform defrosting operation.

[0031] Combination Figure 2 As shown, in step S101, the user selects and activates the self-cleaning mode by operating the air conditioner panel or remote control. In self-cleaning mode, the air conditioner sequentially performs a frosting process and a defrosting process to maintain high efficiency and a clean environment. The frosting process is the first stage of the self-cleaning mode. In this stage, an ice layer forms on the surface of the air conditioner's evaporator (inner pipe). This is because during the air conditioner's cooling operation, water vapor inside the evaporator condenses into water droplets, which then cool and freeze on the evaporator surface. The frosting process reduces the air conditioner's heat dissipation efficiency, requiring regular cleaning to maintain efficient operation. The defrosting process is the second stage of the self-cleaning mode. This stage primarily removes the ice layer formed during the frosting process to restore the air conditioner's heat dissipation efficiency. The defrosting process usually starts within a certain time after frosting is complete; the specific time can be adjusted based on the air conditioner's design and temperature sensor feedback. The defrosting process involves starting the air conditioner's compressor and indoor fan. The high-temperature, high-pressure gas generated by the compressor flows over the evaporator surface, rapidly melting the ice layer and expelling it from the air conditioner.

[0032] Furthermore, self-cleaning mode is an intelligent function in the air conditioning field, improving user experience and energy efficiency. In modern air conditioners, self-cleaning mode is not limited to frosting and defrosting; it can also include other functions such as drying and dehumidification. The integration of these functions makes the air conditioning equipment more intelligent, efficient, and energy-saving during operation. Besides the frosting and defrosting process, modern air conditioners' self-cleaning mode can incorporate other intelligent control and optimization strategies. For example, sensors can monitor indoor temperature and humidity and the air conditioner's operating status, dynamically adjusting the timing and duration of the defrosting process based on real-time data. This allows for more precise control of the defrosting process and improves defrosting efficiency and energy efficiency. Additionally, with the development of smart home technology, self-cleaning mode can be linked with other home appliances. For instance, when indoor humidity is high, the air conditioner can automatically activate the dehumidification function and initiate the defrosting process at an appropriate time to prevent frost buildup, thus providing a more comfortable indoor environment.

[0033] In addition to real-time monitoring and calculation of current temperature changes, the self-cleaning mode can also combine with other sensors and intelligent algorithms to achieve more precise defrosting control. For example, by monitoring indoor humidity with a humidity sensor and combining it with temperature changes, it can more accurately determine when to start and end defrosting, avoiding premature or late defrosting. Based on machine learning algorithms, the air conditioner can predict and optimize the defrosting cycle and defrosting operation parameters based on historical data and environmental change patterns. Through learning from a large amount of data, the air conditioner can automatically adjust its defrosting strategy, making the defrosting process more intelligent and efficient, maximizing energy savings. With the development of IoT technology, the air conditioner can also link with other smart devices to achieve more intelligent self-cleaning functions. For example, by combining with an indoor air quality sensor, the air conditioner can intelligently adjust its settings based on the level of air pollution and temperature changes, providing a more comfortable and clean indoor environment.

[0034] In step S102, during the frosting process in self-cleaning mode, an ice layer forms on the surface (inner pipe) of the air conditioner's evaporator. This is because during the air conditioner's cooling operation, water vapor inside the evaporator condenses into water droplets, which then cool and condense into ice on the evaporator surface. To obtain the temperature of the air conditioner's evaporator's inner pipe and the indoor ambient temperature after the frosting process, the following steps are required:

[0035] After the frosting process is completed, record the current time point T1. Using temperature sensors or temperature probes, measure the temperature of the evaporator surface (inner tube) and the ambient temperature at time T1. The temperature of the evaporator's inner tube is usually lower because the formation of ice makes its surface temperature colder, while the ambient temperature represents the average temperature of the entire room. Finally, the evaporator inner tube temperature and the ambient temperature are measured.

[0036] Furthermore, air conditioners can be equipped with multiple temperature sensors distributed in different locations, such as the evaporator surface and various areas of the room, to acquire temperature data from multiple points in real time. Through the collection of multi-point data, the air conditioner can more accurately understand the evaporator's status and the indoor temperature distribution, thereby achieving more refined defrosting and drying control. Air conditioners can also combine intelligent algorithms to analyze and process temperature data, predicting evaporator frosting conditions and drying timing based on historical data and environmental change patterns, thus optimizing the defrosting and drying process. Intelligent algorithms can dynamically adjust the start timing and duration of defrosting and drying based on real-time data, maximizing energy efficiency and user experience. Modern air conditioners can be linked with smart home systems, enabling remote monitoring and control via network communication and remote control. Users can view the air conditioner's temperature data and operating status in real time through smartphones or other terminal devices, and remotely control and adjust it.

[0037] In step S103, a first temperature change difference is calculated based on the inner tube temperature and the ambient temperature, and this difference is used as the current temperature change difference. This is a crucial step in the self-cleaning control method. This difference is used to determine the frost condition of the evaporator and changes in the indoor environment, thereby enabling corresponding defrosting control. The obtained first temperature change difference is used as the current temperature change difference for subsequent defrosting control steps. The defrosting process continues, and the current temperature change difference is used to determine whether to continue the defrosting operation or begin the drying process.

[0038] Furthermore, the temperature difference threshold can be dynamically adjusted based on different seasons, environments, and usage conditions. For example, in hot summer weather, the frosting speed may be slower, so the temperature difference threshold can be appropriately increased to reduce unnecessary defrosting operations. By combining intelligent algorithms and historical data, the optimal defrosting time can be predicted. By analyzing the trend of evaporator temperature changes, the need for defrosting can be determined in advance, avoiding excessive frosting and energy waste. The self-cleaning control of the air conditioner can be linked with other energy efficiency control systems. For example, by combining indoor light sensors and human body sensors, the operating time of the indoor fan and compressor can be optimized to achieve smarter and more energy-efficient defrosting control.

[0039] In one embodiment, step S103 includes:

[0040] Calculate the first temperature change difference ΔT using the following formula:

[0041] △T=T 内环 -T 管温 , among which, T 内环 T represents the ambient temperature. 管温 This indicates the temperature of the inner tube.

[0042] In this embodiment, the first temperature change difference ΔT is calculated according to the given formula: ΔT = T 内环 -T 管温Based on the initial temperature difference ΔT, the difference between the evaporator inner pipe temperature and the indoor ambient temperature can be determined. This difference information is crucial for subsequent defrosting control. Depending on the magnitude of ΔT, it can be determined whether to continue defrosting or initiate the drying process to optimize the self-cleaning process. Besides the initial temperature difference ΔT, other parameters and algorithms can be introduced to further optimize self-cleaning control. For example, a threshold can be set; when ΔT exceeds this threshold, the defrosting process is initiated. This threshold can be adjusted according to the air conditioner model and design characteristics to achieve the best defrosting effect. Monitoring the rate of change of the evaporator inner pipe temperature and the indoor ambient temperature, and predicting the timing of defrosting termination based on the trend of the rate of change, allows for earlier termination of the defrosting process, reducing energy consumption and improving efficiency. Combining intelligent algorithms and machine learning technology, predictions based on historical data and environmental change patterns optimize the defrosting cycle and defrosting operation parameters, achieving more intelligent and efficient self-cleaning control.

[0043] In step S104, the defrosting process is an important step in the self-cleaning control method. It is used to determine whether defrosting is necessary and to adjust the operating status of the air conditioner's compressor and indoor fan based on the current temperature difference to achieve an efficient defrosting process. After the defrosting process is completed, the temperature of the inner pipe of the air conditioner evaporator and the ambient temperature of the room are obtained. It is then determined whether the current temperature difference is less than a preset threshold. This threshold can be set according to factors such as the air conditioner model, design features, and usage environment. If the current temperature difference is less than the threshold, it indicates that the degree of frost on the evaporator is not high. At this time, it is possible to choose to only turn on the air conditioner's compressor and not turn on the indoor fan. By turning on the compressor, the refrigerant begins to circulate, raising the temperature of the evaporator and melting the ice layer. At the same time, not turning on the indoor fan reduces airflow, thereby accelerating the melting of the ice layer. If the current temperature difference exceeds a preset threshold, it indicates a high degree of frost buildup on the evaporator. In this case, faster defrosting is required. Simultaneously, the air conditioner's compressor and indoor fan should be turned on. By activating the compressor and fan, stronger airflow accelerates the melting of ice and the removal of water droplets from the evaporator surface. This shortens the defrosting process, reduces energy consumption, and improves efficiency. During defrosting, the indoor pipe temperature and ambient indoor temperature are continuously monitored, and the compressor and indoor fan operation is adjusted based on real-time temperature data to achieve optimal defrosting results.

[0044] Furthermore, the threshold settings and operating status adjustments in the defrosting process can be optimized according to different situations. For example, in hot seasons, the air conditioner's frosting speed may be slower, so the threshold can be appropriately lowered to start the defrosting process earlier. Conversely, in cold seasons, the frosting speed is faster, so the threshold can be raised to delay the defrosting operation and avoid frequent defrosting. In addition, with the development of intelligent control technology, the defrosting process can also incorporate intelligent algorithms and machine learning to achieve adaptive defrosting control. Overall, optimizing and intelligentizing the defrosting process is an important direction for air conditioner self-cleaning control. By reasonably setting thresholds, adjusting operating status, and combining the application of intelligent algorithms, a more efficient and energy-saving defrosting process can be achieved, providing users with a better indoor environment.

[0045] In one embodiment, the inner tube temperature and ambient temperature are monitored cyclically after the defrosting operation, and a second temperature change difference is calculated. The second temperature change difference is used as the current temperature change difference, and the defrosting process continues until the defrosting process ends.

[0046] In this embodiment, cyclically monitoring the inner tube temperature and ambient temperature after the defrosting operation is to monitor the temperature changes during the defrosting process in real time, and thus make corresponding defrosting control decisions based on the current temperature difference. During the defrosting operation, the inner tube temperature and ambient temperature will gradually change as defrosting progresses. Therefore, it is necessary to continuously monitor and calculate the current temperature difference to achieve optimized control of the defrosting operation. The specific steps are as follows:

[0047] After the defrosting process is completed, the defrosting process begins. The internal pipe temperature at the start of defrosting is recorded as the initial pipe temperature, and the indoor ambient temperature is recorded as the initial ambient temperature. The internal pipe temperature and the indoor ambient temperature are monitored cyclically, and the current temperature value is obtained periodically or intermittently. The second temperature change difference (i.e., the internal pipe temperature after defrosting minus the ambient temperature after defrosting) is calculated. The second temperature change difference represents the change in internal pipe temperature and ambient temperature during the current defrosting process. The second temperature change difference is used as the current temperature change difference, and defrosting control is judged based on the current temperature change difference. The defrosting process is completed after the current temperature change difference meets the defrosting control judgment criteria.

[0048] In one embodiment, step S104 includes: when the current temperature change difference is greater than 0 degrees and less than a preset threshold, turning on the compressor and not turning on the internal fan to perform a defrosting operation.

[0049] Furthermore, when the current temperature change difference is greater than a preset threshold, the air conditioner's compressor and indoor fan are turned on simultaneously, and the power of the indoor fan is adjusted according to the magnitude of the current temperature change difference, wherein the greater the current temperature change difference, the greater the power of the indoor fan.

[0050] Furthermore, the internal fan includes multiple speed settings, each corresponding to a threshold range; adjusting the power of the internal fan according to the magnitude of the current temperature change difference includes: determining the threshold range to which the current temperature change difference belongs based on the magnitude of the current temperature change difference; and adjusting the internal fan to the corresponding speed setting based on the threshold range.

[0051] In this embodiment, when the current temperature change difference is greater than 0 degrees and less than a preset threshold, the compressor is turned on while the indoor fan remains off to perform defrosting. This stage is suitable for situations where the evaporator has a low degree of frost buildup, and defrosting can be effectively achieved simply by running the compressor. When the current temperature change difference is greater than the preset threshold, it indicates that the evaporator has a high degree of frost buildup, requiring faster defrosting. In this case, both the air conditioner's compressor and indoor fan are turned on simultaneously, and the power of the indoor fan is adjusted according to the magnitude of the current temperature change difference. The larger the current temperature change difference, the greater the power of the indoor fan. The indoor fan includes multiple speed settings, each corresponding to a threshold range. Based on the magnitude of the current temperature change difference, the threshold range to which the current temperature change difference belongs is determined, and the indoor fan is adjusted to the corresponding speed setting according to the threshold range. The specific control method is as follows:

[0052] The current temperature change difference ΔT is a very important parameter in the air conditioning system, reflecting the degree of frost on the evaporator and the temperature difference in the indoor environment. Based on the value of ΔT, the speed of the indoor fan can be intelligently adjusted, thereby achieving efficient defrosting operation and energy saving effect.

[0053] A. When △T is within the threshold range A (20℃≤△T<25℃), select the lowest setting for the indoor fan. Within this temperature difference range, the degree of frost is low, and the defrosting operation only requires the operation of the compressor to effectively melt the ice layer. At this time, the indoor fan is kept at the lowest setting to reduce energy consumption and make the defrosting operation more efficient. Since the degree of frost is low, the defrosting process can be completed in a shorter time, thereby saving energy.

[0054] B. When △T is within the threshold range B (25℃≤△T<30℃), select the medium setting for the indoor fan. Within this temperature difference range, the degree of frost is relatively high, but not very severe. At this time, moderate operation of the indoor fan can speed up the defrosting process and save energy. The indoor fan can quickly discharge water droplets at the medium setting and assist the compressor in speeding up the defrosting process. Due to the high degree of frost, the defrosting process takes a certain amount of time, but efficient defrosting can still be achieved through reasonable adjustment of the indoor fan setting.

[0055] C. When ΔT is within the threshold range C (ΔT≥30℃), select the highest setting for the internal fan. This temperature difference range indicates that the degree of frosting is very severe. At this time, the higher operating setting of the internal fan can expel a large number of water droplets more quickly, thereby accelerating the defrosting process. The strong airflow of the internal fan can effectively expel water droplets from the evaporator surface, making the defrosting process more efficient. Although the internal fan consumes more energy at the highest setting, the defrosting process itself takes a long time due to the severe degree of frosting. Therefore, in this case, by using the highest setting of the internal fan, the defrosting cycle can be significantly shortened, thereby achieving energy-saving effects.

[0056] For example:

[0057] Assuming the self-cleaning mode is activated, and the current temperature difference ΔT is 23℃, falling within threshold range A, the intelligent control strategy will set the indoor fan to its lowest setting, activating only the compressor for defrosting. This reduces energy consumption and makes defrosting more efficient. Since ΔT is within a low threshold range, the defrosting process may only take a few minutes, thus saving energy. Conversely, if ΔT reaches 30℃, falling within threshold range C, indicating severe frost buildup, the indoor fan will be set to its highest setting, simultaneously activating the compressor for defrosting. The highest-setting indoor fan generates strong airflow, rapidly expelling large amounts of water droplets and accelerating the defrosting process. Although the indoor fan consumes more energy at this time, the severe frost buildup and the inherently longer defrosting time mean that using the highest-setting indoor fan significantly shortens the defrosting cycle, achieving energy savings.

[0058] During defrosting, the internal pipe temperature and indoor ambient temperature are continuously monitored, and the operating status and power of the compressor and indoor fan are adjusted based on real-time temperature data to achieve the best defrosting effect. With continuous technological advancements, intelligent systems can be further utilized to optimize defrosting control. For example, by combining temperature sensors and fan controllers, real-time monitoring of evaporator and indoor ambient temperature changes can intelligently adjust the power of the indoor fan to achieve adaptive defrosting control and improve energy efficiency; artificial intelligence algorithms can be used to analyze historical data and environmental parameters to predict defrosting timing and optimal power adjustment strategies, preparing for defrosting in advance and avoiding energy waste; and self-cleaning control can be linked with other smart home devices, such as curtain control and air conditioning temperature adjustment, to optimize indoor temperature and humidity and achieve smarter and more efficient energy management.

[0059] In one embodiment, the self-cleaning mode further includes a drying process following the defrosting process; the air conditioning-based self-cleaning control method further includes turning on the internal fan and running it for a predetermined time period before entering the drying process.

[0060] In this embodiment, the self-cleaning mode also includes a drying process after the defrosting process. After the defrosting process is completed, the ice layer on the air conditioner's inner pipe has melted, but some water droplets may still remain on the evaporator surface. In order to remove the water droplets and further improve the efficiency and cleanliness of the air conditioner, a drying process is introduced. The specific steps are as follows:

[0061] After the frosting process is completed, the defrosting process begins. The system checks if defrosting is finished; if not, it continues to monitor and calculate the temperature difference. After defrosting, the drying process begins. Before entering the drying process, the indoor fan is turned on and runs for a predetermined time period, typically set to t minutes (e.g., 1 minute). This is to accelerate airflow through the indoor fan, helping to remove residual water droplets from the evaporator and thus expedite the drying process. During the drying process, the indoor fan runs continuously, but the compressor is off. The indoor fan continuously circulates indoor air, passing it over the evaporator surface to help completely evaporate and expel residual moisture, keeping the evaporator dry and clean. After the drying process is complete, the self-cleaning mode ends, and the air conditioner returns to normal operation.

[0062] Furthermore, the drying process completely evaporates any remaining moisture on the evaporator, preventing water droplets from re-condensing into ice and thus maintaining the air conditioner's high efficiency and a clean environment. The self-cleaning mode can also be combined with other technologies to achieve a more intelligent and efficient self-cleaning function. For example, the air conditioner can use intelligent algorithms to learn user habits and environmental change patterns, predicting the optimal self-cleaning time and duration, further optimizing the self-cleaning process, and improving energy efficiency and user experience. In addition, with increasing environmental awareness, the self-cleaning mode can also adopt more environmentally friendly materials and technologies, such as using fluorine-free refrigerants and environmentally friendly materials, reducing environmental impact. Simultaneously, the self-cleaning mode can also be integrated with an energy management system to monitor and manage air conditioner energy consumption, maximizing energy savings.

[0063] Specifically, defrosting is the heating mode, where the compressor operates at the frequency required for heating. This achieves energy savings in two ways: First, when the temperature difference is small, simply turning on the compressor at the heating mode frequency is sufficient, while the indoor fan is turned off, thus achieving energy savings. Second, when the temperature difference is large, unlike the traditional mode, the indoor fan is turned on while the compressor runs. Due to the larger temperature difference, the higher indoor temperature accelerates defrosting, significantly reducing the defrosting cycle. This shorter defrosting cycle greatly reduces the compressor's operating time, thus achieving energy savings. The compressor's energy consumption is much higher than the indoor fan's; reducing the compressor's energy consumption further contributes to energy savings.

[0064] In summary, this invention first receives a user's command to enter the air conditioner's self-cleaning mode. The user can activate the self-cleaning mode by operating the air conditioner control panel or remote control. This mode sequentially includes a frosting process and a defrosting process. Then, it acquires the inner pipe temperature of the air conditioner evaporator and the indoor ambient temperature after the frosting process. During the frosting process, the evaporator cools down due to cooling, and the inner pipe temperature decreases accordingly. Simultaneously, the indoor ambient temperature is also monitored. Based on the inner pipe temperature and the ambient temperature, a first temperature change difference is calculated, and this difference is used as the current temperature change difference. The first temperature change difference (ΔT) represents... The degree of frost buildup on the evaporator and the temperature difference in the indoor environment are crucial factors in controlling the subsequent defrosting process. Finally, a judgment is made based on the magnitude of the current temperature difference ΔT: if ΔT is less than a preset threshold, the air conditioner compressor is turned on while the indoor fan is turned off to perform defrosting. This saves energy, as only the compressor needs to operate to complete the defrosting process. If ΔT is greater than the preset threshold, both the air conditioner compressor and the indoor fan are turned on simultaneously, and the power of the indoor fan is adjusted according to the magnitude of ΔT. This accelerates the defrosting process and completes it in a shorter time. This invention's self-cleaning control method for air conditioners dynamically adjusts the defrosting process based on the degree of frost buildup on the evaporator and the indoor temperature, achieving efficient defrosting. Through intelligent control strategies, it saves energy, improves defrosting efficiency, and maintains the performance and stability of the air conditioning system. Users can select the self-cleaning mode when using the air conditioner to enhance its automatic cleaning function, maintain air cleanliness, and provide a more comfortable and healthy indoor environment.

[0082] Since the embodiments of the apparatus and the embodiments of the method correspond to each other, please refer to the description of the embodiments of the method for the embodiments of the apparatus, which will not be repeated here.

[0083] This invention also provides an air conditioning system, including the air conditioning-based self-cleaning control device described above. The air conditioning system includes the air conditioning-based self-cleaning control device, which is an intelligent defrosting control system. This device can adjust the operating status and power of the compressor and indoor fan in real time according to the degree of frost on the evaporator and the ambient temperature, thereby achieving an efficient defrosting process, saving energy, and providing a better indoor environment.

[0084] Specifically, the air conditioning system consists of a compressor, evaporator, condenser, indoor fan, and outdoor fan. The compressor is responsible for circulating the refrigerant, drawing in hot indoor air into the evaporator, cooling it, and then discharging it as cold air. Simultaneously, the condenser dissipates heat outdoors. The indoor fan circulates indoor air, while the outdoor fan exhausts hot outdoor air. A self-cleaning control device is integrated into the air conditioning system. It uses sensors to monitor the evaporator's inner pipe temperature and the indoor ambient temperature in real time, adjusting the defrosting control strategy based on the monitored temperature data.

[0085] The working principle is as follows:

[0086] When the user issues a command to enter the air conditioner's self-cleaning mode, the control device starts working; the air conditioning system enters the frosting process. During this stage, the compressor runs, the evaporator temperature drops, and frost forms. After the frosting process, the first temperature change difference is calculated based on the evaporator's inner pipe temperature and the indoor ambient temperature, which is used as the current temperature change difference. Defrosting control is performed based on the magnitude of the current temperature change difference. When the current temperature change difference is less than a preset threshold, only the compressor is turned on and the indoor fan is turned off to perform the defrosting operation. When the current temperature change difference is greater than the preset threshold, both the compressor and the indoor fan are turned on simultaneously, and the power of the indoor fan is adjusted according to the magnitude of the current temperature change difference. During the defrosting process, the inner pipe temperature and the indoor ambient temperature are continuously monitored, and the operating status and power of the compressor and the indoor fan are adjusted based on real-time temperature data to achieve the best defrosting effect. After defrosting, the drying process begins, and the indoor fan runs for a predetermined period of time to accelerate the discharge of ice water, thereby further drying the evaporator. After the defrosting and drying processes are completed, the self-cleaning mode is finished, and the air conditioning system returns to normal operation.

[0087] Furthermore, with continuous technological advancements, variable frequency technology can adjust the compressor's operating frequency according to actual needs, further optimizing the defrosting process, improving energy efficiency, and reducing energy consumption. Combined with artificial intelligence technology, the system of this invention can learn user habits and environmental changes, predicting the optimal defrosting time and power adjustment strategy, achieving more intelligent and adaptive defrosting control. The self-cleaning control device can also be linked with other smart home devices, such as temperature and humidity sensors and curtain control systems, to optimize the indoor environment and improve energy efficiency. By combining solar energy or other renewable energy sources for power supply, dependence on the traditional power grid is reduced, resulting in a more environmentally friendly air conditioning system.

[0088] This invention also provides an air conditioner, which may include a memory and a processor. The memory stores a computer program, and when the processor calls the computer program in the memory, it can implement the steps provided in the above embodiments. Of course, the air conditioner may also include various network interfaces, power supplies, and other components.
