Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an air purification control method, air conditioner, device, equipment and medium for air conditioners. Background Technology

[0002] Currently, air conditioning products often emit unpleasant odors upon initial startup and switching to cooling mode. A deeper analysis reveals the root cause lies in the unique state of the evaporator under cooling conditions: Firstly, a large amount of condensate rapidly forms on the surface of the evaporator fins. When the fan drives airflow over these moist fins, the condensate evaporates and enters the airflow. If dust, microorganisms, or other organic / inorganic contaminants accumulate on the fin surface, these pollutants are carried away by the evaporated moisture and diffused into the indoor air, directly causing odors. Secondly, evaporator fins are typically coated with protective layers (such as hydrophilic or anti-corrosion coatings) to improve performance and durability. However, these coatings may degrade over long-term use due to natural aging, continuous exposure to high humidity (moisture absorption), or complex chemical reactions with dissolved chemicals in the condensate, releasing low-molecular-weight volatile organic compounds (VOCs). When cooling starts and airflow passes through, these released chemicals are blown out, forming a chemically distinctive odor. Therefore, pollutants carried by the airflow blowing from the surface of the moist evaporator fins or chemicals released from the deteriorated coating together constitute the root cause of odors generated during the initial cooling phase of air conditioning. In summary, existing technologies lack solutions that can effectively suppress or eliminate odor problems during the air conditioning start-up phase from the source. Summary of the Invention

[0003] This invention provides an air purification control method, air conditioner, device, equipment, and medium for air conditioners, aiming to solve the problem of odors accompanying the air during the cooling start-up phase of existing air conditioners.

[0004] In a first aspect, embodiments of the present invention provide an air conditioner, including an air conditioner body and a filter assembly. The air conditioner body is provided with an air inlet, and the filter assembly is disposed at the air inlet. The filter assembly includes a first filter and a second filter and a driving member. The first filter is disposed above the second filter, and the driving member is connected to the first filter and the second filter respectively, for driving the first filter and the second filter to open and close relative to the air inlet to adjust their opening degree.

[0005] Furthermore, the density of the second filter is greater than the density of the first filter.

[0006] Furthermore, the first filter screen is a V-shaped grid filter screen; and / or, the second filter screen is a multi-layered corrugated filter screen arranged in parallel.

[0007] In a second aspect, the present invention also provides an air purification control method for an air conditioner, applied to the air conditioner of the first aspect, the method comprising: If the air conditioner is detected to be turned on and a control command for cooling mode is received, the filter assembly will be adjusted to the minimum opening and the air deflector will be closed, and the fan will be controlled to run at the maximum fan speed. If the fan is detected to be running at the maximum wind speed for a preset time, the compressor is controlled to start to enter the cooling mode. The system can detect the concentration of odorous gases in real time and adjust the opening of the first and / or second filters according to the current concentration of odorous gases and the preset filter adjustment strategy.

[0008] Thirdly, the present invention also provides an air purification control device for an air conditioner, including a unit for performing the above-described method.

[0009] Fourthly, embodiments of the present invention also provide a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the above-described method.

[0010] Fifthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0011] This invention provides an air purification control method, air conditioner, device, equipment, and medium for an air conditioner. By installing a filter assembly comprising a first filter, a second filter, and an independent drive unit at the air inlet of the air conditioner, combined with a corresponding air purification control method, this invention can specifically solve the problem of odors accompanying the air during the cooling start-up phase of existing air conditioners. Firstly, during the initial cooling start-up, the filter assembly is adjusted to its minimum opening, maximizing the filtration area and interception capacity of the two filters. This prevents dust, microorganisms, and other pollutants carried by the evaporator fins due to condensation, or VOCs released from the degradation of the fin protective layer, from entering the room around the filters. Secondly, closing the air deflector and operating the fan at maximum speed forces airflow into a closed-loop circulation within the air conditioner, using the strong airflow to wash away pollutants adhering to the evaporator fins. The first and second filters, at their minimum opening, efficiently adsorb the removed pollutants, preventing them from reattaching to the fins or spreading during internal circulation. After a preset time, the compressor starts and enters cooling mode. At this point, the fins have been cleaned by strong airflow, reducing the source of pollutants spreading with the airflow during subsequent cooling. The opening of the two filters is then adjusted in real time according to the concentration of odor gas. This not only enhances the filtration effect when the odor concentration is high, continuously blocking residual pollutants, but also avoids increased air resistance due to over-filtration when the concentration is low. Ultimately, this effectively solves the odor problem during the cooling start-up phase, improves indoor air quality, and balances the air conditioner's cooling efficiency and energy consumption control, thus improving the user experience.

[0019] In current air conditioner usage, an unpleasant odor often appears during the initial start-up phase of cooling mode, a phenomenon that has become a key pain point affecting user experience. In-depth analysis reveals that the root cause lies in the unique state of the evaporator fins under cooling conditions: on the one hand, a large amount of condensate rapidly condenses on the fin surface. If dust, microorganisms, or other contaminants accumulate on the fin surface, these contaminants will be carried by the evaporated moisture and diffused into the room with the airflow; on the other hand, the protective layer on the fin surface may degrade due to aging, moisture, or chemical reactions during long-term service, releasing low-molecular-weight volatile organic compounds (VOCs). When airflow passes through, these VOCs are blown out, forming a chemical odor. Existing air conditioners lack targeted structural designs and control strategies to effectively address this problem, making the odor issue during the cooling start-up phase difficult to resolve. New technical solutions are urgently needed to improve this situation.

[0020] To address this, this invention proposes an air purification control method, air conditioner, device, equipment, and medium for an air conditioner. By setting up a first and second filter arranged vertically and with independently adjustable opening degrees, and employing a control method that adjusts the filter to its minimum opening and closes the air guide plate while controlling the fan to run at high speed during the cooling start-up phase, a closed-loop airflow is formed inside the air conditioner. This forcefully flushes away dust and pollutants adhering to the evaporator fins, which are then effectively adsorbed by the high-density filter, blocking odor generation at its source. Subsequently, in normal cooling mode, the filter opening degree is dynamically adjusted based on real-time detected odor concentration. When pollution is severe, the filter is closed to enhance filtration; when air quality is good, the filter is opened wider to reduce air resistance. This thoroughly solves the odor problem during the initial cooling phase while achieving an intelligent balance between purification efficiency and air conditioner energy consumption, significantly improving airflow comfort and overall system economy. Details are as follows: Reference Figure 1 and Figure 2 This invention provides an air conditioner, including an air conditioner body and a filter assembly. The air conditioner body has an air inlet, and the filter assembly is disposed at the air inlet. The filter assembly includes a first filter 10, a second filter 20, and a driving member (not shown in the figure). The first filter 10 is disposed above the second filter 20, and the driving member is connected to the first filter 10 and the second filter 20 respectively, for driving the first filter 10 and the second filter 20 to open and close relative to the air inlet to adjust their opening degree.

[0021] Specifically, the air conditioner unit is the basic carrier for the air conditioner to realize its core functions such as cooling and air supply. It has key components such as evaporator, fan, and compressor. The external air inlet is the channel through which indoor air enters the air conditioner unit, providing an airflow source for the air circulation of the air conditioner. The filter assembly is the core structure for filtering air and intercepting pollutants. It is installed at the air inlet to ensure that all air entering the air conditioner unit through the air inlet is filtered by the filter assembly. The first filter 10 and the second filter 20 in the filter assembly are both components with air filtration capabilities. They can be made of common filter materials such as metal mesh and fiber filter media. The two are arranged vertically, with the first filter 10 located above the second filter 20. This vertical arrangement can fully cover the cross-section of the air inlet and avoid filtration blind spots. The driving component can be a stepper motor, servo motor or other power component with precise driving capabilities. It is connected to the first filter 10 and the second filter 20 respectively. The connection method can be gear transmission, linkage transmission or other methods. Through the power output of the driving component, the first filter 10 and the second filter 20 can be driven to rotate or translate relative to the air inlet, thereby changing the obstruction area between the filter and the air inlet and realizing independent adjustment of the opening degree of the two. Specifically, the core cause of odor during the cooling start-up phase is the diffusion of dust and dirt on the evaporator fin surface carried by airflow, as well as VOCs released from the degradation of the fin protective layer. The filter assembly of this invention can achieve graded filtration through a dual-filter structure. The upper first filter 10 can preferentially intercept large particles of dust and dirt in the air (preventing them from contacting the evaporator fins with the airflow and being blown into the room during cooling start-up), while the lower second filter 20 can further filter small particulate impurities and some VOCs, forming a dual protection of "coarse filtration followed by fine filtration," reducing the path of pollutants contacting the evaporator and entering the room. Secondly, the drive unit can adjust the opening and closing degree of the two filters separately. During the initial cooling startup, both filters can be fully closed to maximize the filtration area, ensuring that airflow undergoes dual filtration before reaching the evaporator. This prevents unfiltered airflow containing contaminants from directly impacting the fins and carrying odors. Furthermore, when dynamically adjusting the filter opening based on air quality, independent control of both filters ensures filtration effectiveness while reducing air resistance, preventing incomplete filtration or excessive air resistance caused by fixed filters. Ultimately, the dual-filter's graded filtration and independent adjustment effectively block the critical path for odor generation during the cooling startup phase, achieving the technical effects of reducing indoor odors and improving air cleanliness, while also considering the air conditioner's ventilation efficiency and operational stability. Through this structural design, the air conditioner forms a precisely controllable dual filtration defense at the air inlet, ensuring comprehensive air filtration while flexibly adjusting the filtration intensity according to actual needs. This provides a structural foundation for subsequent control methods to address odor issues during the cooling startup phase and enhances the air conditioner's adaptability to different air quality scenarios.

[0022] In one embodiment, the density of the second filter 20 is greater than that of the first filter 10. Specifically, the second filter 20 is the component in the filter assembly that performs fine filtration. Its density is mainly reflected in the number of pores in the filter material per unit area or the tightness of the fiber arrangement. The higher density allows the second filter 20 to more effectively intercept fine pollutants such as tiny particles and volatile organic compounds in the air. The first filter 10 is the component in the filter assembly that performs coarse filtration. Its density is lower than that of the second filter 20, and its pores are relatively larger. It is mainly used to intercept larger pollutants such as dust, hair, and lint in the air. From the perspective of their cooperation, since the first filter 10 has a lower density and is located above the second filter 20, when the air first passes through the first filter 10, large particulate pollutants are preferentially intercepted, which can prevent large particles from clogging the fine pores of the second filter 20. The air that has undergone preliminary filtration then enters the second filter 20, which has a higher density, to further intercept fine pollutants, forming a "coarse-to-fine" graded filtration mode. Specifically, existing air conditioners using filters of a single density are prone to problems such as "incomplete coarse filtration leading to fine filter clogging" or "excessive fine filter density leading to excessive air resistance," thus affecting filtration efficiency and air conditioner operating efficiency. This embodiment addresses this by setting up a first filter 10 and a second filter 20 with different densities, clearly defining their filtration roles. This allows for efficient interception of pollutants of different sizes during the cooling start-up phase, reducing odor sources, while also preventing filter clogging, thereby solving the odor problem during the cooling start-up phase. Through this density-differentiated design, the filter assembly effectively reduces air resistance during airflow while ensuring filtration effectiveness, reducing the operating load on the air conditioner fan, balancing air purification effect and air conditioner operating efficiency, and extending the filter's lifespan.

[0023] In this embodiment, the first filter 10 is a V-shaped grille filter; and / or, the second filter 20 is a multi-layered, parallel-arranged corrugated filter. Specifically, if the first filter 10 is a V-shaped grille filter, its structural feature is that the filter as a whole is in the shape of a V-shaped channel, and the grilles are arranged at a specified angle to form a continuous V-shaped converging channel. This structure utilizes the principle of aerodynamics and can capture large mass impurities in the air through inertial force. In addition to V-shaped grille filters, the first filter 10 can also be a flat grille filter, an arc-shaped grille filter, etc. Flat grille filters have a simple structure, with the grilles arranged in parallel, making them easy to process and clean. Arc-shaped grille filters can better fit the arc-shaped air inlet and improve the fit with the air inlet. If the second filter 20 is a multi-layered, parallel-arranged corrugated filter, its structural feature is that the filter is composed of multiple layers of corrugated filter sheets stacked together, with each layer of filter sheets forming an undulating corrugated structure on its surface. This structure significantly increases the effective filtration area of ​​the filter. In addition to multi-layered corrugated filters, the second filter 20 can also use pleated fiber filters, honeycomb activated carbon filters, etc. Pleated fiber filters expand the filtration area through their pleated design, while honeycomb activated carbon filters can enhance the removal capacity of volatile organic compounds through the adsorption effect of activated carbon. From the perspective of their cooperation, when the first filter 10 is a V-shaped grid filter and the second filter 20 is a multi-layered corrugated filter, the large particulate pollutants intercepted by the V-shaped grid filter will not clog the small pores of the corrugated filter, and the corrugated filter can deeply purify the air filtered by the V-shaped grid filter. If other types of first filters 10 and second filters 20 are used, synergistic filtration can also be achieved based on the division of labor of "coarse filtration + fine filtration". Specifically, existing air conditioner filters often suffer from low filtration efficiency or high air resistance due to unreasonable structural design, affecting odor removal. This embodiment clarifies the specific structural types of the first filter 10 and the second filter 20, ensuring that the first filter 10 can efficiently perform coarse filtration and the second filter 20 can efficiently perform fine filtration. During the cooling start-up phase, pollutants can be quickly intercepted, reducing odor diffusion and thus solving the odor problem during the cooling start-up phase. By adopting the above-mentioned specific filter structure, not only is the filtration efficiency and dust holding capacity of the filter assembly improved, but air resistance is also reduced while ensuring filtration effect, reducing the energy consumption of the air conditioner and further optimizing the overall performance of the air conditioner and the user experience.

[0024] Please see Figure 3 , Figure 3 This is a flowchart illustrating the steps of an air purification control method for an air conditioner provided in an embodiment of the present invention. The method is applied to the air conditioner described in the above embodiments, which has been detailed in the description and will not be repeated here for the sake of brevity. The method includes steps S110-S130.

[0025] S110. If the air conditioner is detected to be turned on and a control command for the cooling mode is received, the filter assembly is adjusted to the minimum opening and the air guide plate is closed, and the fan is controlled to run at the maximum wind speed. In this embodiment, minimum opening means that the first and second filters in the filter assembly are in a state of maximum obstruction relative to the air inlet. At this time, the overlap area between the filter and the air inlet is the largest, and the filtration area is also the largest. Maximum wind speed means that the fan is running at its designed maximum speed and can output the strongest airflow. Cooling mode control command refers to the signal sent by the user to the air conditioner through operation methods such as remote control and control panel, requesting the air conditioner to enter the cooling working state. Specifically, when the air conditioner's main control system detects that it is in the on state and receives the cooling mode control command sent by the user, it immediately sends a control signal to the drive unit of the filter assembly. After receiving the signal, the drive unit drives the first and second filters to move or rotate, so that both are adjusted to the minimum opening degree, ensuring that the air at the air inlet can be completely filtered by the two filters. At the same time, the main control system sends a signal to the drive mechanism of the air guide plate to control the air guide plate to close, blocking the connection between the air conditioner's air outlet and the indoor environment. In addition, the main control system also sends a signal to the fan to control the fan to switch to the maximum fan speed, so that the fan generates a strong airflow at the highest speed. With the air guide plate closed, this airflow forms a circulation inside the air conditioner and continuously flows over the surface of the evaporator fins. Specifically, existing air conditioners produce odors during the cooling start-up phase primarily because dust, microorganisms, and other contaminants adhering to the evaporator fins are carried into the room by airflow. Furthermore, there is a lack of measures to intercept and clean these contaminants during the initial startup phase. This step addresses this by adjusting the filter to its minimum opening during cooling mode startup to enhance filtration, closing the air deflector to prevent contaminant diffusion, and simultaneously running the fan at maximum speed to flush and remove contaminants from the fins. By controlling contaminants at their source and along their transmission path, the odor problem is resolved. Through these operations, the air conditioner effectively cleans the evaporator fins during the initial cooling start-up phase, while the filter intercepts the flushed contaminants, preventing them from entering the room. This lays the foundation for preventing odors during subsequent normal cooling. The strong internal airflow also quickly cleans the fins, shortening the time before odors may develop.

[0026] S120. If it is detected that the fan is running at the maximum wind speed for a preset time, control the compressor to start to enter the cooling mode. In this embodiment, the preset time refers to the time pre-set based on parameters such as the area of ​​the evaporator fins and the airflow intensity at the maximum fan speed, ensuring that the fan can fully flush the fins and remove surface contaminants when running at maximum speed. The compressor is the core component of the air conditioner to achieve the cooling function. After it is turned on, it can achieve heat exchange through the circulation of refrigerant, allowing the air conditioner to enter the normal cooling state. Specifically, the main control system of the air conditioner will monitor the operating status of the fan in real time, including parameters such as the fan speed and running time. When it is detected that the fan has been running at maximum speed for a preset time, it means that the dust, microorganisms and other contaminants on the surface of the evaporator fins have been fully flushed by the strong airflow and intercepted by the filter at its minimum opening. At this time, the main control system sends a start signal to the compressor. After receiving the signal, the compressor starts to work. The refrigerant circulates between the compressor, evaporator, condenser and other components. The evaporator absorbs heat from the indoor air. After being filtered and cooled, the air will be delivered to the room after the air guide plate is opened, allowing the air conditioner to officially enter the cooling mode. Specifically, if the compressor is turned on and enters cooling mode before the fan has fully cleaned the fins, residual contaminants on the fin surface will be moistened by condensate and diffused with the airflow, causing odor. This step ensures the fins are cleaned by waiting for the fan to run for a preset time before turning on the compressor, preventing contaminants from spreading during cooling and thus solving the odor problem. By controlling these timing points, the air conditioner can enter cooling mode while ensuring the fins are clean. This avoids the odor problem caused by turning on the compressor too early and also avoids energy waste due to excessively prolonged fan operation time, achieving a balance between cleaning effectiveness and energy consumption control.

[0027] S130. Real-time detection of odor gas concentration, and adjustment of the opening degree of the first filter and / or the second filter according to the current odor gas concentration and the preset filter adjustment strategy.

[0028] In this embodiment, the odor gas concentration refers to the content of volatile organic compounds, microbial metabolites, and other substances in the air that cause odors, which is detected and obtained in real time by the gas sensor built into the air conditioner; the preset filter adjustment strategy refers to the rules that are preset according to different odor gas concentration ranges, and adjust the opening degree of the first filter and / or the second filter accordingly. For example, when the concentration is higher than a certain threshold, the degree of filter occlusion is increased, and when the concentration is lower than a certain threshold, the degree of filter occlusion is decreased. Specifically, after the air conditioner enters cooling mode, the built-in gas sensor continuously collects air samples from the room and inside the air conditioner, converting the concentration of odor gases in the samples into electrical signals and transmitting them to the main control system. Upon receiving the concentration signal, the main control system compares it with the concentration threshold in the preset filter adjustment strategy. If the detected odor gas concentration is high, exceeding the first preset threshold, a signal is sent to the drive unit to control both the first and second filters to adjust to a smaller opening, increasing the filtration area and enhancing the interception of odor gases. If the detected odor gas concentration is at a moderate level, between the first and second preset thresholds, only the opening of the second filter is adjusted according to the strategy, keeping the opening of the first filter unchanged, thus reducing air resistance while ensuring filtration effectiveness. If the detected odor gas concentration is low, below the second preset threshold, the first and second filters are controlled to adjust to a larger opening, reducing airflow obstruction. It is understood that the adjustment strategy is not limited to the above; other adjustment strategies can also be used, which are not limited here. Throughout the adjustment process, the drive unit dynamically adjusts the opening of the first and / or second filters according to the instructions of the main control system, ensuring that the filter effect and airflow are adapted to the current odor gas concentration. Specifically, the filter opening of existing air conditioners is mostly fixed and cannot be adjusted according to changes in odor gas concentration, resulting in insufficient filtration when the concentration increases and excessive air resistance when the concentration decreases. This step, by detecting the concentration in real time and adjusting the filter opening according to a preset strategy, ensures effective filtration at different concentrations and avoids over-filtration, thereby continuously solving the odor problem during cooling mode operation. Through the above dynamic adjustment, the air conditioner can flexibly adjust the filtration intensity according to the actual air quality, promptly strengthening filtration when the odor gas concentration increases to prevent odor diffusion, and reducing air resistance when the concentration decreases to ensure cooling efficiency, continuously maintaining indoor air quality and improving the user experience.

[0029] In one embodiment, such as Figure 4 As shown, step S130 includes: S131-S132.

[0030] S131. Determine whether the current concentration of the odorous gas is greater than the first concentration threshold. S132. If the current concentration of odorous gas is greater than the first concentration threshold, then both the first filter and the second filter should be adjusted to their minimum opening.

[0031] In this embodiment, the first concentration threshold is a preset critical value for odor gas concentration, which represents the judgment standard for indoor air quality to be in a state of severe pollution. When the odor gas concentration exceeds this threshold, the highest level of filtration measures need to be activated to block the spread of pollutants. The minimum opening refers to the maximum overlap area between the filter and the air inlet. At this time, the filter has the largest filtration area for air and the strongest ability to intercept pollutants. Specifically, after the main control system of the air conditioner obtains the current concentration of odor gas in real time, it first compares the current detected concentration of odor gas with a pre-stored first concentration threshold to determine the relationship between the two. If the comparison result shows that the current concentration of odor gas is greater than the first concentration threshold, it indicates that the content of pollutants in the room or inside the air conditioner is extremely high. If no strong filtration measures are taken, pollutants are likely to enter the room with the airflow, causing obvious odor. The main control system then sends a control command to the drive unit of the filter assembly. After receiving the command, the drive unit drives the first filter and the second filter to move or rotate, so that both are adjusted to the minimum opening. This ensures that all air passing through the air inlet can be filtered by the two filters in a dual and powerful manner, intercepting pollutants such as dust and volatile organic compounds in the air to the greatest extent. Specifically, existing air conditioners often fail to completely intercept pollutants when odor concentrations are too high due to insufficient filter capacity or inability to fully cover the air inlet. This leads to unpleasant odors. This step first determines whether the concentration exceeds a first concentration threshold, then adjusts both filters to their minimum opening. This activates the strongest filtration mode when pollution is severe, completely blocking the transmission path of pollutants and thus resolving the high-concentration odor problem. Through these steps, the air conditioner can quickly establish a dual, highly effective filtration defense line when odor gas concentrations are severely exceeded, minimizing the amount of pollutants entering the room, effectively suppressing odor generation, and ensuring rapid improvement in indoor air quality, thereby enhancing the user experience in polluted environments.

[0032] In one embodiment, such as Figure 4 As shown, step S130 further includes: S133-S134.

[0033] S133. Determine whether the current concentration of the odor gas is between a first concentration threshold and a second concentration threshold, wherein the second concentration threshold is less than the first concentration threshold; S134. If the current odor gas concentration is between the first concentration threshold and the second concentration threshold, the opening degree of the second filter is adjusted according to the current odor concentration, the first concentration threshold and the second concentration threshold through the first preset opening degree calculation model, and the opening degree of the first filter is kept at the minimum opening degree.

[0034] In this embodiment, the second concentration threshold is a critical value for another odor gas concentration that is lower than the first concentration threshold, representing the standard for determining whether indoor air quality is in a moderately polluted state. The first preset opening / closing degree calculation model is a pre-set mathematical model used to calculate the specific opening degree required for the second filter based on the difference between the current odor gas concentration and the first and second concentration thresholds, ensuring that the filter opening degree matches the pollution level. Specifically, after completing the judgment and ensuring that the current odor gas concentration is not greater than the first concentration threshold, the main control system compares the current odor gas concentration with both the first and second concentration thresholds to determine whether it is between the two. If the current odor gas concentration is determined to be between the first and second concentration thresholds, it indicates that the air quality is moderately polluted and there is no need to activate the highest level of filtration, but targeted enhancement of fine filtration is still required. The main control system then first obtains the specific values ​​of the current odor gas concentration, the first concentration threshold, and the second concentration threshold, and substitutes these values ​​into the first preset opening / closing degree calculation model, which can be as follows: Where C represents the current odor gas concentration, C1 represents the first concentration threshold, and C2 represents the second concentration threshold. The model calculates the appropriate opening value for the second filter and then sends a command to the actuator. The actuator adjusts the opening of the second filter based on the calculation results, while maintaining the first filter at its minimum opening. This ensures the first filter continues to perform its coarse filtration function, intercepting large particulate pollutants and preventing them from affecting the fine filtration effect of the second filter. Specifically, existing air conditioners, when subjected to moderate pollution, may experience problems such as over-filtration leading to increased air resistance or under-filtration resulting in odor residue if a fixed filter opening is used. This step first determines whether the concentration is within the moderate range, then uses the model to calculate the second filter opening while maintaining the first filter at its minimum opening. This allows for dynamic adjustment of the second filter to meet the filtration needs of moderate pollution while ensuring the stable coarse filtration of the first filter, thus solving the odor problem under moderate pollution. Through the above steps, the air conditioner achieves precise control of the filter opening in moderate pollution scenarios, which not only ensures the effective interception of fine pollutants and prevents odor generation, but also avoids increased wind resistance and energy consumption caused by excessive filtration, thus balancing filtration effect and operating efficiency.

[0035] For example, suppose a user turns on the air conditioner in cooling mode on a summer afternoon. At this time, due to residual paint and outdoor pollutants, the indoor odor concentration is 1.8 mg / m³. 3 The preset first concentration threshold is 2.0 mg / m³. 3 The second concentration threshold is 1.0 mg / m³. 3The first preset opening / closing degree calculation model is "Second filter opening / closing degree = (current odor gas concentration - second concentration threshold) / (first concentration threshold - second concentration threshold) × 100%". Specifically, in the calculation, the current concentration of 1.8 mg / m³ is first extracted. 3 Second concentration threshold: 1.0 mg / m³ 3 First concentration threshold: 2.0 mg / m³ 3 Substituting these three key values ​​into the model formula, we arrive at an opening degree of 80% for the second filter. Based on this calculation, the air conditioner will then adjust the second filter to 80% opening while keeping the first filter at its minimum opening. This achieves effective filtration of moderate odors through the higher opening of the second filter, while avoiding excessive filtration that could increase air resistance.

[0036] In one embodiment, such as Figure 4 As shown, step S130 further includes: S135-S136.

Determine whether the current odor concentration is between the second concentration threshold and the third concentration threshold, wherein the third concentration threshold is less than the second concentration threshold; S136. If the current odor concentration is between the second concentration threshold and the third concentration threshold, the opening degree of the first filter is adjusted according to the current odor concentration, the second concentration threshold and the third concentration threshold through the second preset opening degree calculation model, and the second filter is adjusted to the maximum opening degree.

[0038] In this embodiment, the third concentration threshold is a critical value for odor gas concentration below the second concentration threshold, representing a standard for determining whether indoor air quality is good. The second preset opening / closing degree calculation model is another pre-set mathematical model used to calculate the specific opening degree required for the first filter based on the difference between the current odor gas concentration and the second and third concentration thresholds. The maximum opening degree refers to the minimum overlap area between the filter and the air inlet, at which point the filter's obstruction to airflow is minimal, and air circulation is strongest. Specifically, after completing the judgment and ensuring that the current odor gas concentration is not between the first and second concentration thresholds, the main control system compares the current odor gas concentration with both the second and third concentration thresholds to determine whether it falls between them. If the current odor gas concentration is determined to be between the second and third concentration thresholds, it indicates that the air quality is good, requiring only basic coarse filtration, with lower demand for fine filtration. The main control system then first obtains the specific values ​​of the current odor gas concentration, the second concentration threshold, and the third concentration threshold, and substitutes these values ​​into the second preset opening / closing degree calculation model, which can be as follows: Where C represents the current odor gas concentration, C2 represents the second concentration threshold, and C3 represents the third concentration threshold. The model calculates the appropriate opening value for the first filter and then sends a command to the actuator. The actuator adjusts the opening of the first filter based on the calculation results, while simultaneously adjusting the second filter to its maximum opening to reduce airflow obstruction and improve air circulation efficiency. Specifically, in existing air conditioners, if the filter maintains a high filtration intensity when air quality is good, it increases wind resistance and leads to a decrease in cooling efficiency. This step first determines whether the concentration is within a good range, then uses the model to calculate the opening of the first filter and adjusts the second filter to its maximum opening. This achieves basic coarse filtration through dynamic adjustment of the first filter and reduces wind resistance through the maximum opening of the second filter, thus solving the balance problem between filtration and ventilation under good air quality and avoiding increased energy consumption or poor cooling effect indirectly caused by over-filtration. Through the above steps, the air conditioner achieves an optimized balance between filtration intensity and ventilation efficiency when the air quality is good. It can effectively intercept a small number of large particulate pollutants to prevent them from accumulating and causing subsequent odors, while ensuring smooth air circulation, ensuring cooling efficiency, and reducing operating energy consumption.

[0039] For example, assuming the indoor air quality is good in the early morning after nighttime ventilation, the concentration of odorous gas detected during air conditioner operation is 0.6 mg / m³. 3 The pre-set second concentration threshold is 1.0 mg / m³. 3 The third concentration threshold is 0.3 mg / m³. 3 The second preset opening / closing degree calculation model is "First filter opening / closing degree = (Current odor gas concentration - Third concentration threshold) / (Second concentration threshold - Third concentration threshold) × 100%". In specific calculations, the current concentration is first determined to be 0.6 mg / m³. 3 The third concentration threshold is 0.3 mg / m³. 3 Second concentration threshold: 1.0 mg / m³ 3 Substituting these three parameters into the model formula, we obtain that the opening degree of the first filter is approximately 43%. Based on this result, the air conditioner will drive the first filter to adjust to an opening degree of approximately 43%, while simultaneously adjusting the second filter to its maximum opening degree. The first filter's moderate opening degree completes basic coarse filtration, preventing a small amount of large particulate pollutants from entering, while the second filter's maximum opening degree reduces air resistance and ensures cooling efficiency.

[0040] In one embodiment, such as Figure 4 As shown, step S130 further includes: S137-S138.

[0041] S137. Determine whether the current odor concentration is less than the third concentration threshold; S138. If the current odor concentration is less than the third concentration threshold, then both the first filter and the second filter are adjusted to their maximum opening.

[0042] In this embodiment, the third concentration threshold represents the standard for judging whether the indoor air quality is excellent. When the odor gas concentration is below this threshold, there are almost no obvious pollutants indoors, and the need for filtration is extremely low. The maximum opening refers to the smallest overlap area between the filter and the air inlet. At this time, the filter's obstruction of airflow is the weakest, and air can enter the air conditioner through the air inlet with minimal resistance. Specifically, after completing the judgment and ensuring that the current odor gas concentration is not between the second and third concentration thresholds, the main control system compares the current odor gas concentration with the third concentration threshold to determine whether it is less than the third concentration threshold. If the current odor gas concentration is determined to be less than the third concentration threshold, it indicates that the indoor air quality is excellent and almost no additional filtration is needed. The main control system then sends a control command to the drive unit of the filter assembly. After receiving the command, the drive unit drives the first and second filters to move or rotate, adjusting both to the maximum opening to minimize the obstruction of the filter to the airflow, allowing air to quickly and smoothly enter the air conditioner through the air inlet and participate in the cooling cycle. Specifically, existing air conditioners, even with excellent air quality, experience significantly increased air resistance if the filters are still heavily obstructed. This leads to increased fan load, higher energy consumption, and even reduced cooling performance. This step addresses this by first determining if the air concentration is below the third concentration threshold, then adjusting both filters to their maximum opening. This reduces air resistance when excessive filtration is not required, preventing filter obstruction from affecting the air conditioner's normal operation. This solves the energy consumption and efficiency issues caused by over-filtration in excellent air quality, indirectly ensuring no odor-related problems during cooling. Through these steps, the air conditioner achieves optimal airflow in excellent air quality, reducing fan load and energy consumption while maintaining stable cooling efficiency. This allows users to enjoy high-quality air and a superior cooling experience, further enhancing the overall performance of the air conditioner.

[0043] In one embodiment, such as Figure 5 As shown, the method in this embodiment of the invention further includes steps S141-S143.

[0044] S141. Record the opening and closing times of the second filter at its minimum opening, maximum opening, and intermediate opening. S142. The cleanliness of the second filter is determined by a preset cleanliness calculation model based on the opening and closing time of the maximum opening degree, the opening and closing time of the intermediate opening degree, the current odor concentration, the first concentration threshold, and the second concentration threshold. S143. If the cleanliness of the second filter is greater than the preset cleanliness threshold, a filter cleaning prompt message is generated.

[0045] In this embodiment, the opening and closing time refers to the continuous operating time from entering the corresponding opening state to leaving the state when the second filter is at the minimum opening, maximum opening, and intermediate opening respectively; the intermediate opening refers to all non-extreme opening states between the minimum opening and the maximum opening, and its specific value is determined according to the actual odor concentration adjustment result; the preset cleanliness calculation model is a mathematical model that is pre-set and used to quantitatively evaluate the degree of filter pollution by combining the operating time of the second filter at different openings and odor concentration parameters; cleanliness refers to the current degree of pollution of the second filter. The larger the value, the more pollutants accumulated on the filter and the weaker the filtration capacity; the preset cleanliness threshold is the critical value for judging whether the second filter needs to be cleaned or replaced. When the cleanliness exceeds the threshold, the filtration effect of the filter can no longer meet the requirements; the prompt information refers to the signal used to inform the user that the filter needs to be cleaned, which can be presented in the form of text displayed on the air conditioner display panel, flashing lights, or sound prompts.

[0046] Specifically, during air conditioner operation, the main control system monitors the opening status changes of the second filter in real time. Whenever the second filter switches to its minimum, maximum, or intermediate opening, the main control system automatically records the switching time and calculates the continuous opening and closing time when the filter leaves that opening state. Simultaneously, it stores the opening and closing time corresponding to each opening degree in the internal memory. When it is necessary to evaluate the cleanliness of the second filter, the main control system first retrieves the opening and closing time of the second filter at its maximum and intermediate opening degrees from the memory, then obtains the current odor gas concentration, the first concentration threshold, and the second concentration threshold. These parameters are then substituted into a preset cleanliness calculation model, which can be as follows: Where C represents the current concentration of the odorous gas, C1 represents the first concentration threshold, and C2 represents the second concentration threshold. This represents the opening and closing time at the minimum opening degree. This indicates the opening and closing time of the intermediate opening degree. The model calculates the current cleanliness value of the second filter based on the differences in pollutant interception efficiency of the filter at different opening degrees (e.g., the minimum opening degree has the highest interception efficiency and the fastest pollutant accumulation, while the maximum opening degree has the lowest interception efficiency and the slowest pollutant accumulation), combined with the impact of odor concentration on the total amount of pollutants. Subsequently, the main control system compares the calculated cleanliness with the preset cleanliness threshold. If the cleanliness is greater than the preset cleanliness threshold, it indicates that the second filter has accumulated a lot of pollutants. Continued use will lead to a decrease in filtration effect and may even cause secondary pollution. At this time, the main control system generates a filter cleaning prompt and transmits the information to the user through the air conditioner's display panel or other prompt devices. Specifically, existing air conditioners often lack precise monitoring of filter contamination levels, making it difficult for users to determine when to clean the filter. This leads to overuse of the filter, resulting in decreased filtration efficiency and an inability to effectively intercept contaminants, ultimately causing odors to reappear during cooling start-up or operation. This step records the opening and closing times of the filter at different degrees, calculates the cleanliness level based on concentration parameters, and provides timely cleaning reminders. This ensures the filter maintains optimal filtration capacity, preventing recurrence of odor problems caused by filter contamination, thus resolving subsequent odor issues arising from unclear filter cleaning times. Through these steps, the air conditioner achieves intelligent monitoring and reminders for the second filter's cleanliness status. This not only helps users clean the filter promptly, ensuring filtration efficiency and preventing odors caused by contaminant accumulation, but also extends the filter's lifespan, reduces unnecessary filter replacement costs, and improves user convenience and satisfaction.

[0047] For example, suppose that the second filter of a user's air conditioner operated in the past week with the filter in a fully closed state (corresponding to the minimum opening) for a continuous period of 8 hours (T_fully closed) and in a partially closed state (corresponding to the intermediate opening) for a continuous period of 20 hours (T_partially closed). The detected concentration of odor gas, C, is 1.5 mg / m³. 3 The preset first concentration threshold C1 is 2.0 mg / m³. 3 The second concentration threshold C2 is 1.0 mg / m³. 3 The preset cleanliness calculation model formula is: Cleanliness = T_fully closed + T_partially closed × (C - C2) / (C1 - C2). In specific calculations, first extract samples from T_fully closed for 8 hours, T_partially closed for 20 hours, and C = 1.5 mg / m³. 3 C1 2.0mg / m 3 C2 1.0mg / m 3 These parameters are substituted into the formula for calculation, i.e., 8+10=18, and the current cleanliness of the second filter is 18. If the preset cleanliness threshold is 25, the current cleanliness of 18 is less than the threshold, and no cleaning prompt is needed for the time being. If the cleanliness accumulates to more than 25 in the future, a cleaning prompt will be triggered.
