Description

Technical Field

[0001] This utility model relates to the field of air conditioning device technology, and more specifically, to an air conditioning device. Background Technology

[0002] Currently, in order to facilitate the adjustment of the position of the filter element in the air conditioning device, the existing technology generally uses a drive motor connected to the rotating shaft of the filter element. The drive end of the drive motor rotates to drive the filter element to a predetermined position.

[0003] However, because filter elements are generally quite heavy, the existing drive motor-driven method using a rotating shaft often results in poor stability during the filter element's motion switching process. Consequently, the drive stability of the filter element is poor. Utility Model Content

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] like Figures 1 to 4 As shown, an embodiment of this utility model provides an air conditioning device, which includes a housing 10 and a filter assembly 20. The housing 10 has an air inlet 11, an air outlet 12, and an air cavity 13 communicating with both the air inlet 11 and the air outlet 12. The filter assembly 20 includes a guide member 21, a guide rail 22 adapted to the guide member 21, a drive structure 23 spaced apart from the filter member 24, the drive structure 23 being movably disposed along a preset direction and hinged to the filter member 24, the guide member 21 being movably disposed on the guide rail 22 along the extension direction of the guide rail 22, and the movement direction of the drive structure 23 not coinciding with at least a portion of the extension direction of the guide rail 22. The filter member 24 has a filtering position that blocks one of the air inlet 11 and the air outlet 12, or a clearance position that avoids it. When the filter member 24 is in the filtering position, the line connecting the guide member 21 and the drive structure 23 is at a preset angle to the connection between the guide member 21 and the drive structure 23 when the filter member 24 is in the clearance position.

[0056] The air conditioning device provided in this embodiment, by incorporating a drive structure 23 and a guide member 21, guides the movement of the filter element 24 through the cooperation of the drive structure 23 and the guide member 21. This improves the driving stability of the filter element 24, enabling it to stabilize at the filtering position or the avoidance position, facilitating position switching of the filter element 24, and ensuring stable rotation of the filter element 24 to a preset angle. Therefore, the air conditioning device provided in this embodiment solves the technical problem of poor movement stability of the filter element 24 in existing air conditioning devices.

[0057] Specifically, the preset angle is greater than 0° and less than 180°, preferably 90°. In this embodiment, the air conditioning device can be a suspended assembly structure.

[0058] Specifically, in this embodiment, the filter element 24 refers to a device comprising fibers and / or porous materials, capable of removing at least one of dust, mold, and bacteria from the air. The filter element 24 can be a filter support and filter screen, or a structure with adsorbent material, or an electro-adsorption structure that uses electrostatic adsorption. The adsorbent material can be activated carbon, absorbent cotton, foam, pleated paper, cotton, or other materials capable of adsorption. The electro-adsorption structure can adsorb dust through electrostatic dust removal. The filter element 24 can also be called a filter.

[0059] It should be noted that the air conditioning device in this embodiment can be a wall-mounted air conditioner, a floor-standing air conditioner, a humidifier, an air purifier, an air sterilizer, or any other device capable of treating at least one of the following: air temperature, humidity, dust, mold, and bacteria.

[0060] In this embodiment, during the process of the filter element 24 moving from the filtering position to the avoidance position, the drive structure 23 has a first preset trajectory segment and a second preset trajectory along a preset direction, and the guide element 21 has a first guide trajectory and a second guide trajectory along the extension direction of the guide rail 22; the first preset trajectory and the first guide trajectory at least partially overlap, and the second preset trajectory and the second guide trajectory do not overlap, so that the drive structure 23 and the guide element 21 have partially overlapping trajectories, so that the movement of the guide element 21 and the drive structure 23 can be kept consistent to a certain extent, which is convenient for guidance and driving.

[0061] At least one of the second preset trajectory and the second guide trajectory is an arc-shaped trajectory and a straight trajectory set at a predetermined angle to the first preset trajectory. This allows for easy switching of the installation angle of the filter element 24 via the arc-shaped trajectory or the straight trajectory set at a predetermined angle, facilitating the smooth movement of the filter element 24 to the filtering position or the avoidance position. Specifically, the arc-shaped trajectory ensures smooth switching of movement and improves the stability of movement direction switching.

[0062] It should be noted that "at least part of the first preset trajectory and the first guide trajectory coincide" can be understood as at least part of the first preset trajectory and the first guide trajectory extending in the same direction. "The second preset trajectory and the second guide trajectory do not coincide" can be understood as the direction of the second preset trajectory being different from the direction of the second guide trajectory.

[0063] Specifically, both the first preset trajectory and the first guide trajectory are straight lines. This makes it easier for the drive structure 23 and the guide member 21 to move at the first preset trajectory and the first guide trajectory, respectively, and facilitates driving by the drive structure 23 and guiding by the guide member 21.

[0064] In this embodiment, the guide rail 22 has a first guide channel 221 and a second guide channel 222 connected in sequence. The first guide channel 221 extends along a preset direction, and the second guide channel 222 is located on the side of the first guide channel 221 that is closer to or farther from the air inlet 11 or the air outlet 12. This structural arrangement facilitates guiding the filter element 24 to the side closer to the air inlet 11 or the air outlet 12 during its movement from the avoidance position to the filtering position, thereby improving the stability of the filter element 24's position switching.

[0065] Specifically, the connection between the first guide channel 221 and the second guide channel 222 is an arc transition, so that the filter element 24 can smoothly transition at the connection between the first guide channel 221 and the second guide channel 222, thereby improving the stability of the position switching of the filter element 24.

[0066] Specifically, the drive structure 23 is located on the side of the guide member 21 away from the air inlet 11 or the air outlet 12, and the second guide channel 222 is located on the side of the first guide channel 221 closer to the air inlet 11 or the air outlet 12. This facilitates the optimization of the structural layout of the drive structure 23 and the guide member 21, so that when the drive structure 23 is driven, it can indirectly drive the guide member 21 to guide smoothly.

[0067] Specifically, the guide member 21 is positioned above the air inlet 11 or the air outlet 12, and the second guide channel 222 is located below the first guide channel 221. With this structural arrangement, the filter element 24 is positioned below the clearance position. The second guide channel 222 facilitates the smooth and stable entry of the filter element 24 into the second guide channel 222 during its movement from the first guide channel 221 to the second guide channel 222, further improving the stability of the movement switching.

[0068] In one embodiment, the drive structure 23 includes a drive gear, which is rotatably configured. The filter assembly 20 also includes a rack 26 extending in a preset direction and meshing with the drive gear. This design is simple in structure and provides stable drive. Specifically, when the filter element 24 is positioned above the mounting port, the filter assembly 20 further includes a support member for supporting the rotation shaft of the drive gear, ensuring stable meshing between the drive gear and the rack 26. Furthermore, the support member may also have a guide groove adapted to the rotation shaft of the drive gear, the extension direction of which is the same as the first preset trajectory and the second preset trajectory.

[0069] In another embodiment, the drive structure 23 includes a telescopic rod, the telescopic end of which is extendable and retractable along a preset direction. This results in a simple structure for the drive structure 23 and stable driving action.

[0070] Specifically, there are multiple filter components 20, with their clearance positions spaced apart. The air conditioning device also includes an air quality detection unit 30 and a control unit. The air quality detection unit 30 is mounted on the housing 10 to detect the air quality of the environment in which the air conditioning device is located. The air quality detection unit 30 and the drive structures 23 of the multiple filter components 20 are all electrically connected to the control unit. The control unit controls the driving status of the multiple drive structures 23 based on the air quality information detected by the air quality detection unit 30. This arrangement facilitates the driving control of the drive structures 23 based on the air quality information detected by the air quality detection unit 30, ensuring that all multiple filter components 24 are in clearance positions or that at least one of the multiple filter components 24 is in a filtering position, thereby enabling real-time adjustment of the air quality at the air inlet 11 or air outlet 12 of the air conditioning device.

[0071] Specifically, multiple guide rails 22 are spatially staggered to avoid interference between the multiple filter elements 24 and other components, including the guide rails 22, during movement. The multiple guide rails 22 have the same structure but differ in length. Each guide rail 22 only limits the position of the guide element and does not obstruct the normal movement of the filter element 24.

[0072] Specifically, the control unit includes a microcontroller and a central processing unit. The microcontroller processes the detection data from the air quality detection unit 30, and the processed detection data is transmitted to the central processing unit.

[0073] Specifically, the drive structure 23 includes a drive motor and a drive gear, the drive motor drives the drive gear to rotate, and the drive motor is electrically connected to the control unit. Alternatively, the drive structure 23 includes an electric telescopic rod, which is electrically connected to the control unit.

[0074] The air quality detection unit 30 can be installed at the air inlet 11, the air outlet 12, or the outside of the housing 10.

[0075] Specifically, when there are multiple filter components 20, the multiple filter elements 24 of the multiple filter components 20 can all be used to filter or avoid the air inlet 11; or the multiple filter elements 24 of the multiple filter components 20 can all be used to filter or avoid the air outlet 12; or, a portion of the multiple filter elements 24 of the multiple filter components 20 can be used to filter or avoid the air inlet 11, and another portion of the multiple filter elements 24 of the multiple filter components 20 can be used to filter or avoid the air outlet 12.

[0076] In one embodiment, multiple filter elements 24 are arranged at intervals. The control unit controls at least one drive structure 23 to drive the corresponding filter element 24 to the corresponding filter position based on the air quality information detected by the air quality detection unit 30. This facilitates the selection of different filter elements 24 or different numbers of filter elements 24 for filtration, and allows for adaptive adjustment of the positions of multiple filter elements 24 according to air quality information, thereby adapting the filtration effect.

[0077] In another embodiment, the filtration positions of multiple filter elements 24 overlap, and the filtration effects of the multiple filter elements 24 are different. The control unit controls the corresponding filter element 24 to move to the filtration position based on the air quality information detected by the air quality detection unit 30. In this way, it is convenient to select filter elements 24 with different filtration effects for filtration based on different air quality information, so as to ensure the filtration effect while minimizing the impact on the airflow speed of the air conditioning device.

[0078] Specifically, different filtration effects may include at least one of the following: different pressure drops due to different filter pore sizes of filter element 24, different adsorption effects of filter element 24, and different filtration efficiencies of filter element 24.

[0079] Specifically, the multiple filter elements 24 include a filter screen, a high-efficiency filter, and an activated carbon filter. This allows for the selection of at least one filter screen, high-efficiency filter, and activated carbon filter for filtration based on air quality information.

[0080] Among them, screen filters are suitable for environments with good air quality, with low resistance and low power consumption. High-efficiency filters are suitable for environments with moderate air quality, with moderate resistance but higher power consumption. Activated carbon filters are suitable for environments with poor air quality, especially those containing harmful gases, with higher resistance and higher power consumption.

[0081] In this embodiment, the air conditioning device further includes a fan 40, which is disposed within the air cavity 13. The motor of the fan 40 is electrically connected to the control unit, which adjusts the operating frequency or the fan blade speed of the fan 40 according to the operating conditions of the multiple drive structures 23. This structural arrangement facilitates the adjustment of the operating frequency or fan blade speed of the fan 40 based on the driving conditions of the multiple drive structures 23 on the corresponding filter elements 24, thereby adapting the operating frequency or fan blade speed of the fan 40 to the filtration state of the filter elements 24. Specifically, the multiple filter elements 24 include a first filter element 24 and a second filter element 24. The filtration effect of the first filter element 24 is better than that of the second filter element 24. When the first filter element 24 is used for filtration, the fan 40 operates at a first operating frequency; when the second filter element 24 is used for filtration, the fan 40 operates at a second operating frequency. The first operating frequency is greater than the second operating frequency to ensure that there is enough airflow through the air inlet 11 or the air outlet 12 when the first filter element 24 is used for filtration, thus ensuring the air intake or exhaust effect of the air conditioning device.

[0082] Specifically, the air conditioning unit also includes a heat exchanger module 60, which is installed inside the air cavity 13. Specifically, the heat exchanger module 60 can be installed at the air inlet 11.

[0083] Specifically, the filter assembly 20 also includes a position detection element 25, which is electrically connected to the control unit. The position detection element 25 is used to detect the position of the filter element 24, and the control unit controls the drive structure 23 based on the position information detected by the position detection element 25. With this configuration, when the position detection element 25 detects that the filter element 24 has moved from the filtering position to the avoidance position, the control unit controls the corresponding drive structure 23 to stop driving the filter element 24; when the position detection element 25 detects that the filter element 24 has moved from the avoidance position to the filtering position, the control unit controls the corresponding drive structure 23 to stop driving the filter element 24. In this way, the filter element 24 can be prevented from moving to a position beyond the avoidance position or the filtering position, ensuring the switching accuracy of the filter element 24.

[0084] Specifically, the guide rails 22 of multiple filter components 20 are arranged at intervals along a predetermined direction on the side of the housing 10. This structural arrangement facilitates the optimization of the arrangement of the multiple guide rails 22 and avoids motion interference when the filter components 24 move on their respective guide rails 22.

[0085] In one embodiment, multiple filter elements 24 can be arranged vertically at intervals above the housing 10.

[0086] Specifically, when the filter element 24 is in the clearance position, the end of the filter element 24 near the air inlet 11 or air outlet 12 is flush with the mounting surface of the housing 10 where the air inlet 11 or air outlet 12 is located, or is located on the side of the mounting surface of the housing 10 away from the outside of the housing 10 where the air inlet 11 or air outlet 12 is located. This structural arrangement facilitates the storage of the filter element 24 in the clearance position and optimizes its arrangement.

[0087] In the above embodiments, the filter assembly 20 further includes a mounting shell 50, which is disposed on the housing 10 and has a mounting cavity 51. When the filter element 24 is in the clearance position, the filter element 24 is disposed within the mounting cavity 51; when the filter element 24 is in the filtering position, at least a portion of the filter element 24 extends out of the mounting cavity 51. This facilitates the storage and protection of the filter element 24 in the clearance position. By placing the filter element 24 in the clearance position within the mounting cavity 51, the filter element 24 is prevented from being directly exposed to the external environment, thus avoiding its own level of dirt and consequently affecting its filtering effect. It also prevents the filter element 24 from being directly exposed to the external environment for too long, which would lead to accelerated wear and shorten its service life.

[0088] In one embodiment, the end of the mounting housing 50 is provided with a mounting port communicating with the mounting cavity 51; the filter element 24 extends out of the mounting port during movement. This allows the filter element 24 to move smoothly and smoothly enter the filtering position after extending from the mounting port. In this embodiment, the filter element 24 can be a structure that is not easily deformed, for example, it can be a support plate that is not easily deformed, and a filter screen is provided on the support plate.

[0089] In another embodiment, the mounting housing 50 has a mounting through hole communicating with the mounting cavity 51 on the side near the housing 10. The filter element 24 is made of a material with elastic deformation. The filter element 24 has a free end located near the air inlet 11 or the air outlet 12. The mounting housing 50 has an abutting end face spaced apart from the mounting through hole, so that when the filter element 24 moves from the avoidance position to the filtering position, it abuts against the abutting end face, deforms, and passes through the mounting through hole. In this way, the abutting between the filter element 24 and the abutting end face can easily cause the filter element 24 to undergo elastic deformation during its movement from the avoidance position to the filtering position, thereby limiting the movement position of the filter element 24, avoiding the filter element 24 needing to occupy a large space during movement, minimizing the volume of the mounting housing 50, and improving the overall structural compactness of the air conditioning device.

[0090] Specifically, the guide member 21 is a pulley to improve the smoothness of the guide member 21 and reduce the friction of the guide member 21 during the guiding process.

[0091] Specifically, the filter assembly 20 includes a first limiting structure; when the filter element 24 is in the avoidance position, at least one of the filter element 24 and the drive structure 23 engages in limiting contact with the first limiting structure. This facilitates limiting the position of at least one of the filter element 24 and the drive structure 23, thereby ensuring that the filter element 24 is stably positioned in the avoidance position. Specifically, the first limiting structure can be a limiting structure with a limiting contact surface for engaging and limiting contact with at least one of the filter element 24 and the drive structure 23.

[0092] Specifically, the filter assembly 20 includes a second limiting structure; when the filter element 24 is in the avoidance position, the guide element 21 engages with the second limiting structure for limiting. This facilitates limiting the guide element 21 as well, thereby improving the positional stability of the filter element 24 and ensuring that the filter element 24 is stably in the avoidance position.

[0093] Specifically, the filter assembly 20 further includes a third limiting structure; when the filter element 24 is in the filtering position, at least one of the filter element 24 and the drive structure 23 engages in limiting contact with the third limiting structure. This facilitates limiting the position of at least one of the filter element 24 and the drive structure 23, thereby ensuring that the filter element 24 is stably positioned in the filtering position. Specifically, the first limiting structure can be a limiting structure with a limiting contact surface for engaging and limiting contact with at least one of the filter element 24 and the drive structure 23.

[0094] Specifically, the filter assembly 20 also includes a fourth limiting structure; when the filter element 24 is in the filtering position, the guide element 21 engages with the fourth limiting structure for limiting. This facilitates limiting the guide element 21 as well, thereby improving the positional stability of the filter element 24 and ensuring that the filter element 24 is stably positioned in the filtering position.

[0095] By coordinating the various components of the air conditioning unit, filters 24 with different filtration effects are automatically switched according to real-time air quality, thereby optimizing the performance of the air conditioning unit. An air quality detection unit 30 can be installed at the air inlet 11. The air quality detection unit 30 includes multiple sensors for real-time monitoring of air quality parameters in the environment where the air conditioning unit is located. These sensors include a PM2.5 sensor, a PM10 sensor, a temperature sensor, a humidity sensor, and a hazardous gas sensor. The sensor data is fused and processed by a data processing unit (which can be a microcontroller) and then transmitted to the central processing unit.

[0096] In the above embodiment, the driving component, combined with the guide component 21, achieves linear motion and rotary opening and closing motion. Specifically, multiple parallel guide rails 22 are vertically arranged above the housing 10, with a type of filter element 24 mounted flat on each guide rail 22. According to the instructions of the central processing unit, the electric drive gear device (corresponding to the drive structure 23) drives the pulley. The filter element 24, connected to the gear and pulley, moves linearly towards the air inlet 11 or air outlet 12. When the pulley reaches the position of the arc-shaped guide rail 22 (corresponding to the second guide channel 222), it moves downwards along the arc under the influence of gravity. The electric drive gear device continues to move linearly towards the air inlet 11 or air outlet 12, and the filter module rotates 90°, changing from its original horizontal placement to a placement parallel to the air inlet 11 or air outlet 12. Unused filter elements 24 move in the opposite direction back above the housing 10 and are hidden, not directly contacting the outside air. A position sensor is installed at the initial position of each guide rail 22 to detect whether the filter element 24 has been correctly retracted into place (corresponding to the avoidance position); a position sensor is installed at the end of the rack to detect whether the filter element 24 has been placed in place (corresponding to the filtering position). The position sensors feed back the detection results to the central processing unit to ensure the reliability of the switching process.

[0097] By setting multiple detection sensors, air quality parameters in the environment are monitored in real time. A microcontroller is used as the data processing unit. The microcontroller processes the sensor data and transmits it to the central processing unit. The central processing unit determines the current air quality level based on preset thresholds and issues corresponding control commands. The drive circuit controls the action of the drive structure 23 to realize the automatic switching of the filter element 24. The multiple filter elements 24 include a filter screen, a high-efficiency filter, and an activated carbon filter, which are suitable for filtration needs under different air quality conditions. The drive structure 23 can be an electrically driven gear device. When the air conditioning unit switches between different filter elements 24, the electrically driven gear device first drives the pulley. The filter element 24 connected to the gear and pulley moves linearly towards the air inlet 11 or air outlet 12 of the air conditioning unit. When the pulley reaches the position of the arc-shaped guide rail 22 (second guide channel 222), it moves downward along the arc under the action of gravity. The gear device continues to move linearly towards the air inlet 11, and the filter module rotates 90° to move to the position of the air inlet 11. The unused filter moves in the opposite direction back to the top of the unit and is hidden, not directly in contact with the outside air. The unit's variable frequency motor adjusts its frequency according to the filter being switched. This achieves more energy-efficient operation of the air conditioning unit and extends the filter's lifespan.

[0098] like Figure 5As shown, the control method corresponding to the air conditioning device of this utility model includes: acquiring the air quality of the environment in which the air conditioning device is located; and controlling the drive structure 23 of the air conditioning device according to the air quality, so as to drive the filter element 24 of the air conditioning device to move to the filtering position or the avoidance position through the drive structure 23. This method facilitates the control of the drive structure 23 to drive the filter element 24 to the filtering position or the avoidance position according to the air quality, so as to adapt to different air quality conditions and ensure the quality of the airflow entering the air conditioning device or the airflow quality after being regulated by the air conditioning device.

[0099] Specifically, controlling the drive structure 23 of the air conditioning device according to the air quality conditions includes controlling at least one of the multiple drive structures 23 according to the air quality conditions, so that the drive structure 23 drives the corresponding filter element 24 to the filtering position. This method facilitates controlling at least one of the drive structures 23 to drive the corresponding filter element 24 according to the air quality conditions to filter the air inlet 11 and / or the air outlet 12.

[0100] Specifically, the multiple filter elements 24 include a filter screen, a high-efficiency particulate filter (HEPA filter), and an activated carbon filter. At least one of the multiple drive structures 23 is controlled according to air quality conditions, including: determining the air quality level based on the air quality conditions; when the air quality level is good, controlling the filter screen in the multiple filter elements 24 to be in the filtering position; when the air quality level is moderate, controlling the HEPA filter in the multiple filter elements 24 to be in the filtering position; and when the air quality level is poor, controlling the activated carbon filter in the multiple filter elements 24 to be in the filtering position. This allows for easy control of the position of the multiple filter elements 24 according to different air quality levels, so that the filtration effect is adapted to the corresponding air quality level, optimizing the filtration effect on air quality.

[0101] Specifically, the current air quality level can be determined by comparing the detected air quality parameters with preset thresholds and then using the comparison between the parameters and the preset thresholds.

[0102] Specifically, when one of the filter screen, HEPA filter, and activated carbon filter is in the filtration position, the other two are in the avoidance position.

[0103] Specifically, good air quality is better than fair air quality, and fair air quality is better than poor air quality.

[0104] In this embodiment, the control method further includes adjusting the operating frequency or blade speed of the air conditioning device's fan 40 based on the control of the drive structure 23. This facilitates the adaptation of the fan 40's operating frequency or blade speed to the operation of the filter element 24 driven by the drive structure 23. Specifically, filter elements 24 with better filtration effects often have limited airflow. When using a filter element 24 with better filtration effects, the operating frequency or blade speed of the fan 40 is increased accordingly to ensure sufficient airflow through the air inlet 11 or air outlet 12 while maintaining filtration effectiveness.

[0105] like Figure 6 As shown, the control method further includes: controlling the fan 40 to operate at a first operating frequency when the filter screen is in the filtering position; controlling the fan 40 to operate at a second operating frequency when the high-efficiency filter is in the filtering position; and controlling the fan 40 to operate at a third operating frequency when the activated carbon filter is in the filtering position. The first operating frequency is lower than the second operating frequency, and the second operating frequency is lower than the third operating frequency. This method allows for adaptive adjustment of the fan 40's operating frequency based on the switching of the filter elements 24, ensuring that the fan 40's operating frequency matches the switching of the filter elements 24, thus guaranteeing both filtration effectiveness and airflow.

[0106] Specifically, the fan 40 includes fan blades and a motor, and controlling the operating frequency of the fan 40 mainly involves controlling the operating frequency of the motor.

[0107] Correspondingly, the data processing unit of the control unit is responsible for processing the data from the air quality detection unit 30. The central processing unit of the control unit determines the current air quality level based on the data processed by the data processing unit and preset thresholds, and issues corresponding control commands. The specific threshold settings are as follows: Good overall air quality: use a filter; Average overall air quality: use a high-efficiency filter; Poor overall air quality or the presence of toxic gases in the air: use an activated carbon filter.

[0108] The central processing unit (CPU) controls the operation of the electric drive device through the drive circuit to achieve automatic switching of the filter element 24. To ensure that the air conditioning unit maintains a balance between airflow and cooling capacity when the filter element 24 is switched, the air conditioning unit adopts a variable frequency motor control system. The motor of the air conditioning unit's fan 40 is a variable frequency motor, which adjusts its frequency according to the different filter element 24 being switched to maintain a balance between airflow and cooling capacity. Different types of filter elements 24 have different resistance characteristics, thus requiring different airflow speeds to maintain system performance. The CPU switches between different filter elements 24 based on real-time changes in air quality, dynamically adjusting the frequency of the variable frequency motor. The worse the overall air quality, the greater the resistance of the corresponding filter element 24, and the higher the required motor frequency. For example, when the air quality changes from good to moderate, the CPU switches to a high-efficiency filter and correspondingly increases the frequency of the variable frequency motor to maintain a balance between airflow and cooling capacity; conversely, when the air quality changes from moderate to good, the CPU switches to a filter and correspondingly decreases the frequency of the variable frequency motor to save energy.

[0109] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: Improved driving stability of the filter element; reduction of unnecessary energy consumption by automatically switching between filters with different filtration effects; increased energy efficiency ratio of the air conditioning device (which can be an air conditioning system); and reduced operating costs. Unused filters can be hidden, reducing unnecessary wear, extending the service life of the filters, and lowering maintenance costs. Automatic identification of air quality and switching of filters without manual intervention improves the system's intelligence level and enhances the user experience.
