Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a heat exchange component, an air conditioning device, and a control method. Background Technology

[0002] Currently, the air outlet filter of existing air conditioning devices is generally installed directly at the air outlet to ensure airflow efficiency and optimize indoor air quality.

[0003] However, because air outlets often contain air guiding components, air sweeping components, drive structures for driving the air guiding components, and drive structures for driving the air sweeping components, the air outlet layout is often concentrated. Even if the filter at the air outlet in existing technologies is designed to be movable, the drive mechanism for driving the filter will still be located at the air outlet, further exacerbating the over-concentration of the structure and hindering optimization of the air outlet layout. Furthermore, the movable location of the air guiding and sweeping components at the air outlet also poses a risk of interference between the filter structure and the movement of these components.

Overall, this solution not only improves the comfort and purification effect of the air conditioner but also enables intelligent management and maintenance, enhancing user comfort.

[0090] 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.

[0091] like Figures 1 to 6As shown, an embodiment of the present invention provides a heat exchange assembly, which includes an evaporator 10 and a filter structure 20. The evaporator 10 has an air inlet side 11 and an air outlet side 12 disposed opposite to each other. The filter structure 20 is adjustablely disposed at the air outlet side 12 of the evaporator 10 to be in a first filtration state and a second filtration state. When the filter structure 20 is in the first filtration state, the filter structure 20 overlaps the evaporator 10 and forms a closed filter cavity 31 with the evaporator 10, so that the air outlet side 12 exits through the filter cavity 31 and the filter structure 20 in sequence. When the filter structure 20 is in the second filtration state, the filter structure 20 is spaced apart from the evaporator 10 and forms a communication gap 32, and the air outlet side 12 exits through the communication gap 32 or the filter structure 20.

[0092] Since the filter structure 20 in this embodiment is located on the evaporator 10, it maintains a certain distance from the air outlet of the air conditioning unit, and may even be entirely located within the air conditioning unit. This avoids the technical problem of excessive structural concentration at the air outlet, or even motion interference, caused by the filter structure 20 being installed at the air outlet. Furthermore, the installation position of the filter structure 20 also helps to avoid safety issues due to its exposure, ensuring the overall aesthetic appearance of the air conditioning unit. It also provides good adjustability for the filter structure 20, allowing it to adapt to various modes and ensuring operational reliability. Therefore, the heat exchange component provided in this embodiment can solve the technical problem in the prior art where the filter screen installed at the air outlet causes excessive structural concentration at the air outlet, or even motion interference.

[0093] It should be noted that "so that the air outlet side 12 passes through the filter chamber 31 and the filter structure 20 in sequence" can be understood as the air outlet side 12 passing through the filter chamber 31 and the filter structure 20 in sequence. "The air outlet side 12 passes through the connecting gap 32 or the filter structure 20" can be understood as the air outlet side 12 passing through the connecting gap 32 or the filter structure 20.

[0094] Specifically, the airflow of the evaporator 10 is directed to enter from the air inlet side 11 for heat exchange, and then exit from the air outlet side 12 after heat exchange.

[0095] The heat exchange component provided in the embodiments of the present invention achieves airflow control through dynamic adjustment of the filter structure 20, satisfying both the need for rapid cooling and ensuring air purification. The effect is evident in the initial operation of the air conditioning device: the filter structure 20 is in the second filtration state, reducing airflow resistance and accelerating the adjustment of indoor temperature and / or humidity; while when the indoor temperature or humidity approaches the set value, the filter structure 20 switches to the first filtration state, enhancing air purification capabilities and improving indoor air quality. In practice, when the air conditioner is turned on, the state of the filter structure 20 is adjusted according to the difference between the indoor temperature and the set temperature to achieve optimal temperature regulation and air purification.

[0096] Specifically, the switching between the first and second filtration states, and the adjustment of the size of the connecting gap 32 in the second filtration state, can adapt to the needs of different operating modes. By adjusting the filter structure 20 on the air outlet side 12 to different states, different effects can be achieved; specifically, in the first filtration state, the air outlet can be filtered, improving air outlet uniformity and reducing air outlet noise. Specifically, in the second filtration state, the air outlet resistance can be reduced, improving the air supply effect of the air conditioner and achieving better comfort.

[0097] Specifically, the air conditioning device mentioned in this invention can be an air conditioner or a humidifier, or other device that can be used to regulate air temperature and / or humidity.

[0098] It should be noted that the "closed filter chamber 31" can disregard some gaps caused by installation, assembly, production, or overlapping fit. The closed filter chamber 31 can be formed by overlapping the evaporator 10 and the filter structure 20; or, the closed filter chamber 31 can be formed by overlapping the evaporator 10, the filter structure 20, and other components (the other components can be at least a part of the indoor unit housing 60 of the air conditioning unit).

[0099] Specifically, the filter structure 20 can be set with an adjustable angle relative to the evaporator 10; or, the distance between the filter structure 20 and the evaporator 10 can be adjusted; or, both the angle and distance between the filter structure 20 and the evaporator 10 can be adjusted. In this way, by changing the relative position between the filter structure 20 and the evaporator 10, the control of airflow can be further refined to achieve a better balance between airflow resistance and filtration effect, enabling the air conditioning system to maintain efficient operation under a wider range of conditions. Adjustable angle and / or distance settings improve the flexibility and adaptability of the heat exchange components, allowing for rapid response and providing suitable air handling effects in high or low temperature, high or low humidity environments.

[0100] In this embodiment, the heat exchange assembly also includes a drive structure 40, which is driven and connected to the filter structure 20 to form a crank 41 slider structure. Utilizing the characteristics of the crank 41 slider mechanism, combined with the partial rotational and partial linear motion of the filter structure 20, precise positioning and stable movement of the filter structure 20 are achieved. This simplifies the control process, improves the reliability and accuracy of the motion, and also reduces maintenance costs. In operation, under the action of a control signal, the drive structure 40 drives the filter structure 20 to move, thereby achieving the switching of the filtration state.

[0101] Specifically, the filter structure 20 has a first connecting portion 21 and a second connecting portion 22 spaced apart. The drive structure 40 includes a crank 41 and a mounting plate 42. The crank 41 is rotatably mounted and is driven to the first connecting portion 21 to rotate the filter structure 20 to either a first filtration state or a second filtration state. The mounting plate 42 is provided with a guide groove 421, and the second connecting portion 22 is movably mounted within the guide groove 421 along its extension direction. The principle of this design is to achieve multi-degree-of-freedom adjustment of the filter structure 20 through the drive connection between the crank 41 and the first connecting portion 21, and the movement of the second connecting portion 22 within the guide groove 421, allowing for both angle and distance adjustments. This significantly improves the adjustment range and precision of the filter structure 20, enabling the air conditioning system to more precisely control airflow and achieve better performance in both rapid cooling and deep purification. The specific usage process can be as follows: under the control command, the crank 41 rotates to drive the first connecting part 21, while the second connecting part 22 moves in the guide groove 421. Under the combined action, the filter structure 20 completes the state transition.

[0102] In this embodiment, the filter structure 20 has a first end and a second end that are arranged opposite to each other. When the filter structure 20 is in the first filtration state, the first end or the second end overlaps the evaporator 10. Specifically, the first connecting part 21 is located at the first end, and the second connecting part 22 is located at the second end; or, both the first connecting part 21 and the second connecting part 22 are located between the first end and the second end. The above connection methods are simple and stable, and can achieve stable driving and positioning of the filter structure 20, ensuring the stability of the filter structure 20 in different states, avoiding shaking or deviation caused by movement, and improving the smoothness and sealing of the filter structure 20's movement. Especially in the first filtration state, it can effectively prevent unfiltered air from passing directly, ensuring the air purification effect. Specifically, when the filter structure 20 is in the first filtration state, the first end or the second end is tightly attached to the evaporator 10, ensuring the sealing of the filter chamber 31, thereby achieving efficient air purification.

[0103] Specifically, the mounting plate 42 is provided with guide arc grooves 422 spaced apart from the guide grooves 421. The crank 41 has a hinged end spaced apart and a rotating end rotatable relative to the hinged end. The hinged end is mounted on the mounting plate 42, and the rotating end is rotatably disposed within the guide arc grooves 422 along the extending direction of the guide arc grooves 422. Guided by the guide arc grooves 422, the rotating end of the crank 41 can move along a predetermined path, thereby ensuring the smoothness and accuracy of the filter structure 20 during movement. The effect is to improve the motion control capability of the filter structure 20, making it more stable during state transitions and reducing noise and vibration during movement.

[0104] Specifically, by combining the guide groove 421 and the guide arc groove 422, the airflow and noise of the filter structure 20 can be effectively controlled, thereby improving user comfort under different conditions.

[0105] Specifically, the guide groove 421 extends vertically. During use, the rotating end of the crank 41, guided by the guide groove 422, precisely controls the movement trajectory of the filter structure 20, ensuring smooth movement and low noise.

[0106] In this embodiment, the mounting plate 42 is fixedly connected to the evaporator 10 to improve the installation stability of the mounting plate 42.

[0107] Specifically, the mounting plate 42 is located on the air outlet side 12 to optimize the structural layout and facilitate effective guidance of the movement of the filter structure 20.

[0108] Specifically, the mounting plate 42 is set at the end of the heat exchange pipe 13 of the evaporator 10, so as to affect the heat exchange surface of the heat exchange pipe 13 of the evaporator 10 and effectively ensure the heat exchange effect.

[0109] The aforementioned arrangement of the mounting plate 42 improves the structural stability and reliability of the entire heat exchange assembly, ensuring good working condition even during long-term operation or frequent state transitions. During use, the mounting plate 42 provides a stable base for the fixed connection between itself and the evaporator 10, and the filter structure 20 is effectively supported during movement, ensuring smooth operation and structural stability.

[0110] In this embodiment, the heat exchange assembly further includes a water receiving tray 50, which is connected to the evaporator 10 and located at the bottom of the evaporator 10 and the filter structure 20. In the first and second filtration states, the projection of the water-receiving surface of the filter structure 20 onto the water receiving tray 50 is located within the water receiving tray 50. This structural arrangement utilizes the water receiving tray 50 to collect the condensate generated by the filter structure 20 in both the first and second filtration states, ensuring smooth condensate drainage and the stability of the filter structure 20. Thus, when cleaning of the filter structure 20 is required, it can be cleaned using condensate, which facilitates the condensate entering the water receiving tray 50, improving the self-cleaning capability and operating efficiency of the heat exchange assembly, reducing maintenance frequency, and maintaining good air handling performance.

[0111] Specifically, the evaporator 10 is inclined relative to the vertical direction, and the rotating connection end of the filter structure 20 rotates around a preset rotation center. The rotating connection end has a first limit rotation angle and a second limit rotation angle, and the rotating connection end rotates between the first limit rotation angle and the second limit rotation angle.

[0112] Specifically, when the rotating connection end is at its first limit rotation angle, the filter structure 20 is in a first filtration state; when the rotating connection end is at its second limit rotation angle, the filter structure 20 is in a second filtration state. As the rotating connection end moves from the first limit rotation angle to the second limit rotation angle, the distance between the rotating connection end and the evaporator 10 gradually increases. At the first limit rotation angle, the filter structure 20 and the evaporator 10 are tightly fitted together, forming a closed filter chamber 31, achieving efficient purification. At the second limit rotation angle, the filter structure 20 and the evaporator 10 are spaced apart, forming a connecting gap 32, achieving rapid cooling. This allows for gradual adjustment of the distance between the two states during the transition from the first to the second filtration state, improving the precision of the adjustment.

[0113] When the rotating connection end is at its first limit rotation angle, the filter structure 20 is inclined to the vertical direction; when the rotating connection end is at its second limit rotation angle, the filter structure 20 extends vertically. By tilting the evaporator 10 at the first limit rotation angle, precise positioning of the filter structure 20 in different states is achieved. The vertical orientation of the evaporator 10 at the first limit rotation angle, combined with gravity, improves the natural drainage efficiency of condensate, ensuring that the condensate on the filter structure 20 can fully flow into the water collection tray 50. Preferably, the condensate on the filter structure 20 is used to clean it, and the cleaned water flows into the water collection trough 51 of the water collection tray 50 under gravity. This improves the self-cleaning ability and operating efficiency of the heat exchange components, while reducing friction between the filter structure 20 and the evaporator 10, extending the equipment's lifespan.

[0114] Specifically, the guide arc groove 422 has a first limiting end and a second limiting end located at both ends of the guide arc groove 422. When the crank 41 rotates to the position that abuts against the first limiting end and the second limiting end respectively, the first limiting end and the second limiting end are used to abut and limit the rotating end of the crank 41, so that the filter structure 20 is at the first limit rotation angle and the second limit rotation angle respectively.

[0115] In this embodiment, the filter structure 20 includes a main body 23 and an operation part 24 connected to each other, with the operation part 24 located on top of the main body 23. This facilitates operation of the filter structure 20 via the operation part 24. Specifically, the filter structure 20 includes a support frame 231 and a filter screen 232, with the filter screen 232 detachably mounted on the support frame 231. The operation part 24 is located on top of the filter screen 232 to facilitate the installation and removal of the filter screen 232 relative to the support frame 231 via the operation part 24.

[0116] Specifically, the operating part 24 is a handle.

[0117] The main body 23 has a waste air side and a clean air side near the evaporator 10, and the operation part 24 protrudes from the waste air side and / or the clean air side. This facilitates operation via the operation part 24, making it convenient for the user.

[0118] Specifically, the operating section 24 is made of metal. This allows condensation to form quickly on the operating section 24, facilitating the cleaning of at least a portion of the filter screen 232 by the rapidly formed condensation.

[0119] In summary, the protruding design and material selection of the operating part 24 improve the operability and durability of the filter structure 20. It also utilizes the thermal conductivity of the metal material to enhance condensate formation and drainage. This simplifies the operation of the filter structure 20, improves its resistance to damage in harsh environments, and enhances the self-cleaning capability of the heat exchange components. The structural design of the operating part 24 allows users to easily pull or push the filter structure 20 to switch states; simultaneously, the metal material of the operating part 24 facilitates condensate formation in the first filtration state, thereby enabling the filter structure 20 to self-clean.

[0120] Specifically, in this embodiment, the filter structure 20 is mounted on the evaporator 10, and the filter screen 232 moves on the air outlet side 12 of the evaporator 10. The filter structure 20 includes a filter screen 232, a support frame 231, a mounting plate 42, and a drive structure 40. The drive structure 40 includes a motor 43 for driving the crank 41 to rotate. Specifically, the support frame 231 has a mounting groove located on its side, and the filter screen 232 is mounted inside the support frame 231 and can be pulled out. The filter screen 232 can be a regular filter screen 232 or a HEPA filter screen 232. The motor 43 drives the crank 41, which is mounted on the support frame 231. The crank 41 then drives the support frame 231, and the crank 41 moves within the guide arc groove 422 of the mounting plate 42, causing the support frame 231 to move accordingly. The guide groove 421 and the guide arc groove 422 on the mounting plate 42 restrict the movement of the support frame 231. Specifically, the driving structure 40 can drive the filtering structure 20 to switch between a first filtering state and a second filtering state; for example... Figure 4 and Figure 5 As shown, when the drive structure 40 is in the second filtration state, the size of the communication gap 32 between the filter structure 20 and the evaporator 10 can be changed, allowing the filter structure 20 to move to different positions. Figure 4 As shown, in the second filtering state and when the connecting gap 32 is at its maximum, the filter structure 20 is basically in a vertical position; as Figure 6 As shown, in the first filtration state, the filter structure 20 is close to the evaporator 10. Besides the two boundary positions mentioned above, as... Figure 5 As shown, the filter structure 20 can also move within a certain range in the second filtration state. Specifically, the corresponding position can be controlled by the motor 43. In different positions, the support frame 231 of the filter structure 20 will be located at different positions on the guide rail to achieve different functions. Specifically, the angle difference between the filter structures 20 corresponding to the above two boundary positions can be between 40° and 60°. Preferably, the angle difference between the filter structures 20 corresponding to the above two boundary positions can be set to 45°. When the filter structure 20 is in the first filtration state, it is equivalent to performing overall filtration, which improves the filtration effect of the filter structure 20 and achieves better air outlet effect and lower noise overall.

[0121] like Figure 7 and 8As shown, Embodiment 2 of the present invention provides an air conditioning device, including: an indoor unit housing 60 and the aforementioned heat exchange component. The indoor unit housing 60 has an air inlet 61 and an air outlet 62 spaced apart. At least a portion of the aforementioned heat exchange component is disposed within the indoor unit housing 60, and the filter structure 20 of the heat exchange component is located between the air outlet side 12 of the evaporator 10 and the air outlet 62. By integrating the aforementioned heat exchange component into such an air conditioning device, and utilizing the dynamic adjustment capability of the filter structure 20, intelligent control of indoor air quality and temperature can be achieved. This improves the operating efficiency and user comfort of the air conditioning device, reduces energy consumption, and lowers maintenance costs. During operation, the air conditioning device automatically adjusts the state of the filter structure 20 based on real-time monitoring of indoor temperature and air quality to achieve optimal temperature regulation and air purification effects.

[0122] Specifically, an air outlet component 100 is provided at the air outlet 62, and the air inlet side 11 is located on the side of the air outlet side 12 that is close to the air inlet 61.

[0123] Specifically, the air conditioning device in this embodiment can be an air conditioner or a humidifier, etc., used to regulate the temperature and / or humidity of the air.

[0124] Specifically, when the filter structure 20 is in the first filtration state, the filter structure 20, the inner wall of the indoor unit housing 60, and the evaporator 10 form a closed filter chamber 31. Through the tight fit between the filter structure 20, the inner wall of the indoor unit housing 60, and the evaporator 10, a closed filter chamber 31 is formed, effectively preventing the direct flow of unfiltered air and improving air purification efficiency. This structural arrangement enables efficient purification and temperature regulation of the air conditioning unit, improving indoor air quality while reducing energy consumption. Specifically, when the air conditioning unit is running, the filter structure 20 is in the first filtration state, tightly fitted with the inner wall of the indoor unit housing 60 and the evaporator 10 to form a closed filter chamber 31, ensuring that all air passing through the evaporator 10 is purified by the filter structure 20, thus improving indoor air cleanliness.

[0125] Specifically, the air outlet 62 is located at the top of the indoor unit housing 60, and the air inlet 61 is located below the air outlet 62. This structural layout facilitates top-mounted airflow and optimizes the airflow pattern.

[0126] Specifically, both the evaporator 10 and the filter structure 20 are housed inside the indoor unit casing 60. This arrangement of the evaporator 10 ensures its effective heat exchange. Furthermore, the fact that both the evaporator 10 and the filter structure 20 are located inside the indoor unit casing 60 prevents them from being exposed outside the casing, thus ensuring both overall operational safety and aesthetics.

[0127] Specifically, the air conditioning device in this embodiment can effectively filter the air conditioner's exhaust air, reducing noise and improving the user experience. The air conditioning device in this embodiment mainly adopts a square air conditioning unit with top-discharge. This type of air conditioning unit draws air in from the left and right sides of the lower front edge and discharges air from the upper side of the indoor unit casing 60. This cools the air from the lower side and blows it upwards, creating a cooling circulation within the room. In places with high cooling requirements (such as computer rooms), it can achieve good energy-saving effects. The air conditioner mainly includes an air intake component, a fan assembly, a heat exchanger assembly, a volute component 90, a baffle plate 70, and a chassis component 80. The intake air is blown upwards by the fan assembly, and after heat exchange and filtration by the heat exchanger assembly, it is discharged. Specifically, the indoor unit casing 60 also includes a decorative panel 63, an air intake panel 64, and a side panel assembly 65.

[0128] Embodiment 3 of the present invention provides a control method applicable to the air conditioning device described above. The control method includes a cleaning process for cleaning the filter structure 20 of the air conditioning device. Figure 9As shown, the cleaning process and corresponding cleaning method include: controlling the air conditioning unit to cool down and ensuring the evaporator 10's pipe temperature is below the dew point temperature; controlling the filter structure 20 to be in a first filtration state, and after a first preset time in the first filtration state, controlling the filter structure 20 to be in a second filtration state and extending it vertically; after a second preset time in the second filtration state, controlling the air conditioning unit to heat up to dry the filter structure 20. Through the alternating operation of cooling and heating, combined with the state transitions of the filter structure 20, automatic cleaning and drying of the filter structure 20 are achieved. Utilizing the natural drainage of condensate and the drying effect of hot air, the cleanliness and effectiveness of the filter structure 20 are maintained. The implementation effect is improved self-maintenance capability of the air conditioning unit, reduced manual intervention, lower maintenance costs, and extended equipment lifespan. In cleaning mode, the air conditioning unit first cools the evaporator 10, lowering its pipe temperature below the dew point, causing condensation at the filter structure 20. Then, the filter structure 20 switches to its first filtration state to collect the condensate. Next, it switches to its second filtration state, allowing the condensate to drain naturally under gravity. Finally, the air conditioning unit heats the filter structure 20 to dry it, ensuring it is dry and clean, thus completing the entire cleaning process. Furthermore, the combined action of the motor 43 in the drive structure 40 during this cleaning process enables comprehensive cleaning, further enhancing the cleaning effect.

[0129] Specifically, during the heating process of the air conditioning device, the cleaning method also includes switching the filter structure 20 from the second filtration state to the first filtration state. By readjusting the state of the filter structure 20 during the heating process, it is possible to fully heat and dry the filter structure 20.

[0130] Specifically, during the heating process of the air conditioning unit, the cleaning method also includes: controlling the operating fan baffle of the air conditioning unit during heating to be larger than that during cooling. By raising the operating fan baffle during heating, the filter structure 20 is thoroughly dried, ensuring its dryness and cleanliness for the next use. This improves the self-maintenance capability of the air conditioning unit, reduces maintenance frequency, and maintains good air handling performance.

[0131] Specifically, during the heating process, the air conditioning unit switches the filter structure 20 from the second filtration state to the first filtration state. The heat generated by the evaporator 10 and the wind force of the high-speed fan are used to deeply dry the filter structure 20, ensuring that it is dry and clean, thereby improving the self-maintenance capability and long-term operational reliability of the air conditioning unit.

[0132] In this embodiment, the cleaning method further includes ensuring that the first absolute temperature difference value corresponding to the temperature difference between the tube temperature and the dew point temperature of the evaporator 10 is greater than or equal to 3°C. By controlling the temperature difference between the tube temperature and the dew point temperature of the evaporator 10, a sufficient amount of condensate is formed, thereby improving the cleaning effect. This enhances the self-cleaning capability of the air conditioning unit, reduces maintenance frequency, and maintains good air handling performance. In cleaning mode, by controlling the tube temperature of the evaporator 10 to be more than 3°C below the dew point temperature, the air conditioning unit promotes rapid condensation of moisture in the air, forming a large amount of condensate, thereby improving the cleaning effect and ensuring the cleanliness and effectiveness of the filter structure 20. Furthermore, the aforementioned temperature difference setting, combined with the fact that at least a portion of the filter structure 20 is made of metal, facilitates the rapid formation of condensate.

[0133] Specifically, when cleaning filter 232 is initiated, filter structure 20 is in the first filtration state, which is closer to evaporator 10. At this time, evaporator 10 is cooled, with the pipe temperature >3°C lower than the dew point temperature. The air conditioner is set to low fan speed. Since the top handle of support frame 231 (including the handle on operating part 24) is made of metal, condensation will form on its surface, and the condensate will flow downwards. After more than 10 minutes, filter structure 20 is adjusted to the second filtration state and placed in a vertically extending direction. The condensate will then flow to the lower part of filter structure 20, onto drip tray 50, and through the drain pipe connected to drip tray 50, clean filter 232. After the condensate dripping is complete, filter structure 20 returns to the first filtration state, and the air conditioner is turned on for heating, increasing the fan speed to medium fan speed to dry filter 232. After this process, the air conditioner is turned off, completing the full cleaning process for filter 232.

[0134] Specifically, the cleaning of the filter screen 232 can be combined with the vibration of the motor 43. Specifically, since the guide arc groove 422 has a first limiting end and a second limiting end located at both ends of the guide arc groove 422, when the crank 41 rotates to the position abutting against the first and second limiting ends respectively, the filter structure 20 is at the first and second limit rotation angles respectively. Thus, when abutting against the first and second limiting ends respectively, the motor 43 will also vibrate due to the limiting effect, thereby causing the crank 41 to vibrate, resulting in the entire filter structure 20 vibrating, thus facilitating better drainage of condensate from the filter structure 20.

[0135] In this embodiment, the control method further includes an adjustment method for regulating the temperature of the indoor space where the air conditioning device is located using the air conditioning device; the adjustment method includes: activating the air conditioning device, acquiring a second absolute temperature difference value corresponding to the temperature difference between the indoor environment where the air conditioning device is located and the set temperature, and / or the air mass fraction corresponding to the indoor environment; and adjusting the filter structure 20 according to the second absolute temperature difference value and / or the air mass fraction corresponding to the indoor environment. This facilitates finding an optimal balance between filtration effect and airflow resistance, ensuring smooth airflow while maintaining filtration effect and improving air quality.

[0136] Specifically, the filter structure 20 is adjusted based on the second absolute temperature difference and / or the corresponding air quality fraction in the indoor environment. This includes controlling the filter structure 20 to switch to a first filtration state or a second filtration state based on the second absolute temperature difference, and ensuring that the second absolute temperature difference corresponding to the first filtration state is less than the second absolute temperature difference corresponding to the second filtration state. By monitoring the temperature difference between the indoor temperature and the set temperature in real time, the state of the filter structure 20 is intelligently adjusted, achieving dual optimization of temperature regulation and air purification. This improves the operating efficiency of the air conditioning device and user comfort, reduces energy consumption, and also lowers maintenance costs.

[0137] Specifically, the filter structure 20 is adjusted based on the second absolute temperature difference value and / or the corresponding air quality fraction of the indoor environment. This includes controlling the filter structure 20 to be in a second filtration state when the air quality fraction of the indoor environment is greater than or equal to a preset air quality fraction value. This ensures smooth airflow even when the indoor air quality is relatively good. Specifically, the air quality fraction of the indoor environment can be obtained by commonly using a weighted average of values ​​combining PM2.5, nitrogen dioxide, and other comprehensive values. When the air quality fraction of the indoor environment is greater than or equal to the preset air quality fraction value, the corresponding indoor air quality is considered relatively good.

[0138] Specifically, by adopting the above method, the air conditioning device automatically adjusts the state of the filter structure 20 based on real-time monitoring of the indoor temperature and the set temperature during operation, so as to achieve the best temperature regulation and air purification effect, and ensure the comfort and health of the indoor environment.

[0139] In this embodiment, controlling the filter structure 20 to switch to either a first filtration state or a second filtration state based on a second absolute temperature difference value includes: comparing the second absolute temperature difference value with a first preset temperature difference value; if the second absolute temperature difference value is less than the first preset temperature difference value, controlling the filter structure 20 to be in the first filtration state and controlling the air conditioning device to operate at a first operating fan speed; if the second absolute temperature difference value is greater than or equal to the first preset temperature difference value, controlling the filter structure 20 to be in the second filtration state and controlling the air conditioning device to operate at a fan speed higher than the first operating fan speed. By setting a temperature difference threshold, the state of the filter structure 20 and the level of the operating fan speed are intelligently determined, achieving a dynamic balance between temperature regulation and air purification. This improves the operating efficiency of the air conditioning device and user comfort, reduces energy consumption, lowers maintenance costs, and extends equipment life.

[0140] It should be noted that "windshields larger than the first operating windshield" means that the wind speed corresponding to windshields larger than the first operating windshield is greater than the wind speed of the first operating windshield.

[0141] Specifically, when the second absolute temperature difference is greater than or equal to the first preset temperature difference, rapid cooling is achieved, reducing the air outlet resistance at the air outlet side 12.

[0142] Specifically, the first preset temperature difference value can be set to 1℃.

[0143] In this way, when the air conditioning unit is running, it automatically adjusts the status of the filter structure 20 and the level of the operating windshield based on real-time monitoring of the indoor temperature and the set temperature, so as to achieve the best temperature regulation and air purification effect, ensuring the comfort and health of the indoor environment, while reducing energy consumption and maintenance costs.

[0144] In this embodiment, when the second absolute temperature difference is greater than or equal to the first preset temperature difference, the adjustment method further includes: comparing the second absolute temperature difference with the second preset temperature difference, wherein the second preset temperature difference is greater than the first preset temperature difference; when the second absolute temperature difference is greater than the second preset temperature difference, controlling the communication gap 32 between the filter structure 20 and the evaporator 10 to be the maximum gap, and controlling the air conditioning device to operate at the second operating fan speed; when the second absolute temperature difference is less than or equal to the second preset temperature difference, controlling the communication gap 32 between the filter structure 20 and the evaporator 10 to be less than the maximum gap, and controlling the air conditioning device to operate at the third operating fan speed; wherein the second operating fan speed is greater than the third operating fan speed. By setting multiple temperature difference thresholds and operating fan speed levels, fine control of the filter structure 20 is achieved to adapt to temperature regulation and air purification needs under different temperature difference conditions. This improves the operating efficiency and user comfort of the air conditioning device, reduces energy consumption, lowers maintenance costs, and extends equipment life. Specifically, when the air conditioning unit is running, it automatically adjusts the connection gap 32 between the filter structure 20 and the evaporator 10 and the level of the operating windshield based on real-time monitoring of the indoor temperature and the set temperature, so as to achieve the best temperature regulation and air purification effect, ensuring the comfort and health of the indoor environment, while reducing energy consumption and maintenance costs.

[0145] It should be noted that "the second operating windshield is greater than the third operating windshield" means that the wind speed of the second operating windshield is greater than the wind speed of the third operating windshield.

[0146] Specifically, the second preset temperature difference value can be set to 8°C to 15°C (including the endpoint values ​​of 8°C and 15°C).

[0147] Specifically, the adjustment method further includes: acquiring the operating time of the air conditioning device; controlling the filter structure 20 to be in a first filtration state when the operating time is within a sleep period; and adjusting the filter structure 20 according to the second absolute temperature difference value and / or the air quality fraction corresponding to the indoor environment when the operating time is outside a sleep period. By monitoring the operating time of the air conditioning device, intelligently determining whether it is in a sleep period and combining this with the determination of the air quality fraction, the state of the filter structure 20 is adjusted, achieving quiet operation and optimized air purification at night. This improves the operating efficiency of the air conditioning device and the user's nighttime comfort, reduces nighttime operating noise, and maintains good air treatment performance.

[0148] Specifically, the sleep period can be from 22:00 to 6:00, that is, from 10 pm to 6 am.

[0149] Specifically, when the air conditioning unit is running at night, it automatically adjusts the filter structure 20 to the first filtration state to reduce operating noise while maintaining good air purification effect, ensuring the comfort and health of users when they rest at night.

[0150] Specifically, when the mass fraction corresponding to the indoor environment is greater than or equal to the preset mass fraction value, the filter structure 20 is controlled to be in the second filtration state, that is, to make the filter structure 20 and the evaporator 10 have a communication gap 32, and to reduce the speed of the air conditioning unit's fan, reduce resistance, and significantly improve the operating efficiency of the air conditioning unit and the user experience.

[0151] From the above description, it can be seen that the embodiments of the present invention achieve the following technical effects: They solve the technical problems of low cleaning efficiency and high maintenance difficulty of the filter structure on the air outlet side, and improve the cleaning efficiency of the filter structure. Furthermore, the cleaning method in this application can adapt to the complex internal structure of air conditioning devices, and simplifies the disassembly and cleaning process of the fan blades and fan cavity, avoiding the risk of water ingress or damage to components, and reducing maintenance costs and safety hazards. It solves the technical problem of a single air supply mode and limited operating performance of air conditioning, while also achieving flexible air supply control and noise reduction. It can intelligently adjust the air supply state according to factors such as ambient temperature and air quality, preventing the filter structure from excessively blocking the wind in certain situations, affecting the air conditioning operating efficiency and air supply effect, thus improving the environmental adaptability of the filter structure and enabling the air conditioning device to achieve efficient and energy-saving operation. It makes the moving mechanism of the filter structure simple in structure, low in cost, high in operating efficiency, and occupies little space, optimizing the overall design and installation layout of the air conditioner, and ensuring functional optimization and performance improvement of the air conditioning equipment.

[0152] The new motion structure optimizes the airflow and comfort of traditional air conditioners. It features guide grooves and guide arc grooves, which enable the movement of the filter structure within a limited space while allowing for adjustable position control. Combined with the control of the evaporator, fan, and environment, it can clean the filter and improve the comfort of air conditioning use.
