Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning devices, and in particular to a heat exchange component, an air conditioning device and a control method. Background Art

[0002] At present, the air outlet filter of the air conditioning device in the prior art is generally directly arranged at the air outlet to ensure the air outlet effect and optimize the indoor air quality.

[0003] However, since the air outlet often has an air guide component, an air sweep component, a driving structure for driving the air guide component to guide the air, and a driving structure for driving the air sweep component to sweep the air, the air outlet often has a concentrated layout. Even if the filter at the air outlet in the prior art is set as a movable structure, the driving mechanism for driving the filter will also be set at the air outlet. This will further cause the structure at the air outlet to be too concentrated, which is not conducive to optimizing the structural layout at the air outlet. In addition, since the air guide component and the air sweep component are arranged movably at the air outlet, there is also a risk that the filter structure will interfere with the movement of the air guide component and the air sweep component.

[0090] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0091] like Figures 1 to 6As shown, an embodiment of the present invention provides a heat exchange component, 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 arranged relatively to each other; the filter structure 20 is adjustably arranged at the air outlet side 12 of the evaporator 10 to be in a first filtering state and a second filtering state; when the filter structure 20 is in the first filtering state, the filter structure 20 is overlapped on the evaporator 10 and forms a closed filter cavity 31 with the evaporator 10, so that the air outlet side 12 discharges air through the filter cavity 31 and the filter structure 20 in turn; when the filter structure 20 is in the second filtering state, the filter structure 20 is spaced apart from the evaporator 10 and forms a connecting gap 32, and the air outlet side 12 discharges air through the connecting gap 32 or the filter structure 20.

[0092] Since the filter structure 20 in this embodiment is disposed on the evaporator 10, the filter structure 20 is at a certain distance from the air outlet of the air conditioning device, and may even be entirely located within the air conditioning device. This avoids the technical problem of excessive concentration of structures at the air outlet or even motion interference caused by the filter structure 20 being installed at the air outlet. In addition, the installation position of the filter structure 20 can also facilitate the avoidance of safety issues caused by the exposure of the filter structure 20, thereby ensuring the overall aesthetic appearance of the air conditioning device, making the filter structure 20 more adjustable and adaptable to various modes, and ensuring the operational reliability of the filter structure 20. Therefore, the heat exchange assembly provided in this embodiment can solve the technical problem in the prior art of excessive concentration of structures at the air outlet or even motion interference caused by the filter screen being installed at the air outlet.

[0093] It should be noted that "so that the air on the air outlet side 12 sequentially passes through the filter cavity 31 and the filter structure 20 to discharge air" can be understood as so that the air on the air outlet side 12 sequentially passes through the filter cavity 31 and the filter structure 20 to discharge air. "The air on the air outlet side 12 discharges air through the connecting gap 32 or the filter structure 20" can be understood as the air on the air outlet side 12 flows out through the connecting gap 32 or the filter structure 20.

[0094] Specifically, the direction of the wind of the evaporator 10 is that the air enters from the air inlet side 11 for heat exchange, and the air is discharged from the air outlet side 12 after heat exchange.

[0095] The heat exchange assembly provided by the embodiment of the present invention is used to control the air flow through the dynamic adjustment of the filter structure 20, which can not only meet the demand for rapid cooling but also ensure the air purification effect. The implementation effect is reflected in that at the initial operation of the air conditioning device, the filter structure 20 is in the second filtering state, which reduces the resistance to air circulation and speeds up the indoor temperature and / or humidity adjustment speed; and when the indoor temperature or humidity approaches the set value, the filter structure 20 switches to the first filtering state, enhancing the air purification ability and improving the indoor air quality. The use process is to adjust the state of the filter structure 20 according to the difference between the indoor temperature and the set temperature when the air conditioner is turned on to achieve the best temperature regulation and air purification effect.

[0096] Specifically, the switching between the first and second filtering states, as well as the ability to adjust the size of the communication gap 32 in the second filtering state, can adapt to the needs of different operating modes. By adjusting the filtering structure 20 on the air outlet side 12 to different states, different effects can be achieved. Specifically, in the first filtering state, the outgoing air can be filtered, improving airflow uniformity and reducing airflow noise. Specifically, in the second filtering state, the outgoing air resistance can be reduced, improving the air supply quality of the air conditioner and achieving a more comfortable experience.

[0097] Specifically, the air conditioning device mentioned in the present invention may be an air conditioner or a humidifier, etc., which can be used to adjust the temperature and / or humidity of the air.

[0098] It should be noted that the term "enclosed filter chamber 31" disregards any gaps resulting from installation, assembly, production, or overlapped fit. The enclosed filter chamber 31 can be formed by overlapping the evaporator 10 and the filter structure 20; alternatively, the enclosed filter chamber 31 can be formed by overlapping the evaporator 10, the filter structure 20, and other components (the other components may be at least a portion of the indoor unit housing 60 of the air conditioning device).

[0099] Specifically, the filter structure 20 can be set so that the angle relative to the evaporator 10 is adjustable; or the filter structure 20 can be set so that the distance relative to the evaporator 10 is adjustable; or the filter structure 20 can be set so that both the angle and the distance relative to the evaporator 10 are adjustable. In this way, by changing the relative position between the filter structure 20 and the evaporator 10, the control of the air flow can be further refined to find a better balance between air flow resistance and filtering effect, so that the air conditioning system can maintain efficient operation under a wider range of conditions. By setting the angle and / or distance adjustable, the flexibility and adaptability of the heat exchange component are improved, and it can respond quickly and provide appropriate air treatment effects regardless of whether it is in a high or low temperature, high humidity or low humidity environment.

[0100] In this embodiment, the heat exchange assembly further includes a drive structure 40, which is operatively connected to the filter structure 20 and forms a crank 41-slider structure. By 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 motion of the filter structure 20 are achieved. This simplifies the control process, improves the reliability and accuracy of motion, and reduces maintenance costs. During operation, the drive structure 40 drives the filter structure 20 in motion under the action of a control signal, achieving a transition between filter states.

[0101] Specifically, the filter structure 20 has a first connection portion 21 and a second connection portion 22 that are spaced apart. The drive structure 40 includes a crank 41 and a mounting plate 42. The crank 41 is rotatably arranged and is driven and connected to the first connection portion 21 to drive the filter structure 20 to rotate to the first filtering state or the second filtering state. A guide groove 421 is provided on the mounting plate 42, and the second connection portion 22 is movably arranged in the guide groove 421 along the extension direction of the guide groove 421. The principle of this design is that through the driven connection between the crank 41 and the first connection portion 21, and the movement of the second connection portion 22 in the guide groove 421, the filter structure 20 can be adjusted with multiple degrees of freedom, which can change both the angle and the distance. In this way, the adjustment range and accuracy of the filter structure 20 are greatly improved, allowing the air conditioning system to more finely control the air flow, and achieve better performance whether it is rapid cooling or deep purification. The specific use process may be: under the control instruction, the crank 41 rotates to drive the first connecting part 21, and the second connecting part 22 moves in the guide groove 421, and under the joint action, the filtering structure 20 completes the state conversion.

[0102] In this embodiment, the filter structure 20 has a first end and a second end that are relatively arranged; when the filter structure 20 is in the first filtering state, the first end or the second end is overlapped on the evaporator 10. The first connection part 21 is located at the first end, and the second connection part 22 is located at the second end; or, the first connection part 21 and the second connection part 22 are both located between the first end and the second end. The above-mentioned connection method is simple and stable, and both 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 movement smoothness and sealing of the filter structure 20. Especially in the first filtering 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 filtering state, the first end or the second end is tightly fitted to the evaporator 10, ensuring the sealing of the filter cavity 31, thereby achieving efficient air purification.

[0103] Specifically, the mounting plate 42 is provided with a guide arc groove 422 spaced apart from the guide groove 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 groove 422 along the extending direction of the guide arc groove 422. Guided by the guide arc groove 422, the rotating end of the crank 41 can move along a predetermined path, thereby ensuring smoothness and precision during the movement of the filter structure 20. This has the effect of improving the motion control capability of the filter structure 20, making it more stable during transitions, and reducing noise and vibration during movement.

[0104] Specifically, through the combination of the guide groove 421 and the guide arc groove 422, the air outlet and noise of the filter structure 20 can be effectively controlled, thereby improving the comfort of the user based on different situations.

[0105] Specifically, the guide groove 421 extends in the vertical direction. During use, the rotating end of the crank 41 is guided by the guide arc groove 422 to accurately control 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 effectively guide the movement of the filter structure 20 .

[0108] Specifically, the mounting plate 42 is disposed 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 , thereby effectively ensuring the heat exchange effect.

[0109] The aforementioned arrangement of mounting plate 42 enhances the structural stability and reliability of the entire heat exchange assembly, maintaining optimal operating conditions even during extended operation or frequent state transitions. During use, mounting plate 42 provides a stable base for the fixed connection between evaporator 10 and mounting plate 42, effectively supporting filter structure 20 during movement, ensuring smooth movement and structural stability.

[0110] In this embodiment, the heat exchange assembly further includes a water receiving pan 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 filtering states, the water receiving surface of the filter structure 20 on the water receiving pan 50 is projected within the water receiving pan 50. With this structural arrangement, the water receiving pan 50 collects condensed water generated by the filter structure 20 in the first and second filtering states, ensuring smooth drainage of the condensed water and stability of the filter structure 20. Thus, when the filter structure 20 needs to be cleaned, it can be cleaned with condensed water, which facilitates the entry of condensed water into the water receiving pan 50. This improves the self-cleaning capability and operating efficiency of the heat exchange assembly, reduces maintenance frequency, and maintains good air treatment performance.

[0111] Specifically, the evaporator 10 is tilted 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] When the rotating connection end is at the first extreme rotation angle, the filter structure 20 is in the first filtering state; when the rotating connection end is at the second extreme rotation angle, the filter structure 20 is in the second filtering state; as the rotating connection end moves from the first extreme rotation angle to the second extreme rotation angle, the distance between the rotating connection end and the evaporator 10 gradually increases. At the first extreme rotation angle, the filter structure 20 and the evaporator 10 fit tightly together, forming a closed filter chamber 31, achieving efficient purification; at the second extreme rotation angle, the filter structure 20 and the evaporator 10 are spaced apart, forming a connecting gap 32, achieving rapid cooling. This facilitates the switching process from the first filtering state to the second filtering state, allowing for a gradual increase or decrease in the distance to improve control accuracy.

[0113] When the rotating connection end is at the first extreme rotation angle, the filter structure 20 is tilted relative to the vertical direction; when the rotating connection end is at the second extreme rotation angle, the filter structure 20 extends in the vertical direction. By tilting the evaporator 10 at the first extreme rotation angle, the filter structure 20 is precisely positioned in different states; by vertically arranging the evaporator 10 at the first extreme rotation angle, while utilizing the effect of gravity, the natural discharge efficiency of condensed water is improved, so that the condensed water on the filter structure 20 can be fully collected into the water receiving tray 50. Preferably, the condensed water on the filter structure 20 is used to clean the filter structure 20, and the cleaned water will flow into the water receiving groove 51 of the water receiving tray 50 under the action of gravity. In this way, the self-cleaning ability and operating efficiency of the heat exchange component are improved, while the friction between the filter structure 20 and the evaporator 10 is reduced, thereby extending the life of the equipment.

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

[0115] In this embodiment, the filter structure 20 includes a main body 23 and an operating portion 24, which are interconnected. The operating portion 24 is located on top of the main body 23. This facilitates operation of the filter structure 20 via the operating portion 24. Specifically, the filter structure 20 includes a support frame 231 and a filter screen 232. The filter screen 232 is detachably mounted on the support frame 231. The operating portion 24 is disposed on top of the filter screen 232, facilitating installation and removal of the filter screen 232 relative to the support frame 231 via the operating portion 24.

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

[0117] The main body 23 has a dirty air side and a clean air side close to the evaporator 10, and the operating portion 24 is protruded from the dirty air side and / or the clean air side. In this way, it is easy to operate through the operating portion 24, which is convenient for users to operate.

[0118] Specifically, the operating portion 24 is made of metal material, so that condensed water is quickly formed on the operating portion 24, and at least a portion of the filter screen 232 is cleaned by the quickly formed condensed water.

[0119] In summary, the protruding design and material selection of the operating portion 24 improve the controllability and durability of the filter structure 20, while also utilizing the thermal conductivity of the metal material to enhance the formation and discharge of condensate. This simplifies the operation of the filter structure 20, improves its resistance to damage in harsh environments, and enhances the self-cleaning ability of the heat exchange component. The structural design of the operating portion 24 allows the user to easily pull or push the filter structure 20 to achieve state transitions; at the same time, the metal operating portion 24 facilitates the formation of condensate in the first filtering state, thereby achieving self-cleaning of the filter structure 20.

[0120] Specifically, the filter structure 20 in this embodiment is assembled on the evaporator 10, and the filter 232 structure moves on the air outlet side 12 of the evaporator 10. The filter structure 20 includes a filter 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 slot located on the side. The filter 232 is assembled within the support frame 231 and can be pulled out. The filter 232 can be a conventional filter 232 or a HEPA filter 232. The motor 43 drives the crank 41, which is assembled with the support frame 231. The crank 41 in turn drives the support frame 231. 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 grooves 421 and 422 on the mounting plate 42 will limit the movement of the support frame 231. Specifically, the driving structure 40 drives the filtering structure 20 to switch to the first filtering state and the second filtering state; Figure 4 and Figure 5 As shown, when the driving structure 40 is in the second filtering state, the size of the communication gap 32 between the filtering structure 20 and the evaporator 10 can also be changed, so that the filtering structure 20 can be moved to different positions. Figure 4 As shown, in the second filtering state and when the communication gap 32 is the largest, the filtering structure 20 is substantially in a vertical position; Figure 6 As shown, in the first filtering state, the filtering structure 20 is close to the evaporator 10. In addition to the above two boundary positions, as shown Figure 5 As shown, the filter structure 20 can also move within a certain range in the second filtering state. Specifically, the corresponding position can be controlled by the motor 43. In the case of different positions, the support frame 231 of the filter structure 20 will be located at different positions of 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 filtering state, it is equivalent to performing overall filtering, which improves the filtering effect of the filter structure 20 and achieves better air outlet effect and lower noise as a whole.

[0121] like Figure 7 and 8As shown, a second embodiment of the present invention provides an air conditioning device, comprising: an indoor unit housing 60 and the aforementioned heat exchange assembly, wherein the indoor unit housing 60 is provided with an air inlet 61 and an air outlet 62 spaced apart; the aforementioned heat exchange assembly, at least partially disposed within the indoor unit housing 60, and the filter structure 20 of the heat exchange assembly located between the outlet side 12 of the evaporator 10 of the heat exchange assembly and the air outlet 62. Such an air conditioning device integrates the aforementioned heat exchange assembly into the device, utilizing the dynamic adjustment capabilities of the filter structure 20 to achieve intelligent control of indoor air quality and temperature. 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.

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

[0123] Specifically, the air conditioning device in this embodiment may be a device such as an air conditioner or a humidifier for adjusting the temperature and / or humidity of the air.

[0124] Specifically, when the filter structure 20 is in the first filtering 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 close cooperation 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, which effectively prevents the direct circulation of unfiltered air and improves the air purification effect. With such a structural setting, it is possible to achieve efficient purification and temperature regulation of the air conditioning device, improve the indoor air quality, and also reduce energy consumption. Specifically, when the air conditioning device is running, the filter structure 20 is in the first filtering state, tightly fitting with the inner wall of the indoor unit housing 60 and the evaporator 10, forming a closed filter chamber 31, ensuring that all air passing through the evaporator 10 is purified by the filter structure 20, thereby improving the cleanliness of the indoor air.

[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. With such a structural layout, it is possible to facilitate top air outlet and optimize the air outlet mode.

[0126] Specifically, the evaporator 10 and the filter structure 20 are both disposed within the indoor unit housing 60. Thus, the arrangement of the evaporator 10 can effectively ensure the heat exchange effect of the evaporator 10. The evaporator 10 and the filter structure 20 are both located within the indoor unit housing 60, which prevents the evaporator 10 and the filter structure 20 from being exposed outside the indoor unit housing 60, thereby ensuring overall operational safety and aesthetics.

[0127] Specifically, the air conditioning device in this embodiment can effectively filter the air-conditioning outlet, reduce noise and improve user experience. The air conditioning device in this embodiment mainly adopts a square air-conditioning cabinet with upper air outlet. This type of air-conditioning cabinet takes in air from the left and right sides of the lower edge of the front side and discharges air from the upper side of the indoor unit housing 60. It can cool the air on the lower side and blow it to the upper edge, causing the cold air to drop. At the same time, it also blows the cold air on the lower side upward, realizing a cold cycle in the room. In places with high cooling demand (such as machine rooms, etc.), it can achieve better energy-saving effects. The air conditioner mainly includes an air intake component, a fan assembly, a heat exchanger assembly, a volute component 90, a windshield 70, a chassis component 80 and other structures. The intake air is blown upward through the fan assembly, and is then discharged after heat exchange and filtration through the heat exchanger assembly. Specifically, the indoor unit housing 60 also includes a decorative panel 63, an air intake panel 64 and a side panel assembly 65.

[0128] The third embodiment of the present invention provides a control method applicable to the air conditioning device provided above, the control method includes entering a cleaning process for cleaning the filter structure 20 of the air conditioning device. Figure 9As shown, the cleaning method corresponding to the cleaning process includes: controlling the air conditioning device to perform cooling and making the tube temperature of the evaporator 10 lower than the dew point temperature; controlling the filter structure 20 to be in a first filtering state, and after a first preset time in the first filtering state, controlling the filter structure 20 to be in a second filtering state and making the filter structure 20 extend in the vertical direction; after a second preset time in the second filtering state, controlling the air conditioning device to perform heating to dry the filter structure 20. By alternating between cooling and heating operations, combined with the state transition of the filter structure 20, automatic cleaning and drying of the filter structure 20 is achieved, and the natural discharge of condensed water and the drying effect of hot air are utilized to maintain the cleanliness and effectiveness of the filter structure 20. The implementation effect is to improve the self-maintenance capability of the air conditioning device, reduce manual intervention, and also reduce maintenance costs and extend the life of the equipment. In cleaning mode, the air conditioning device first operates in cooling mode, lowering the tube temperature of the evaporator 10 below the dew point, thereby causing moisture to condense in the filter structure 20. The filter structure 20 then switches to a first filtering state to collect the condensed water. The filter structure 20 then switches to a second filtering state, allowing the condensed water to drain naturally under the action of gravity. Finally, the air conditioning device operates in heating mode to dry the filter structure 20, ensuring it is dry and clean, thus completing the cleaning process. Furthermore, the aforementioned cleaning process, combined with the impact of the motor 43 in the drive structure 40, enables comprehensive cleaning, further enhancing the cleaning effect.

[0129] Specifically, during the heating process of the air conditioning device, the cleaning method further includes: controlling the filter structure 20 to switch from the second filtering state to the first filtering state. By adjusting the state of the filter structure 20 again during the heating process, the filter structure 20 can be fully heated and dried.

[0130] Specifically, while the air conditioner is controlling heating, the cleaning method further includes controlling the operating damper of the air conditioner during heating to be larger than the operating damper during cooling. By raising the operating damper during heating, the filter structure 20 is thoroughly dried, ensuring it is dry and clean for the next use. This improves the self-maintenance capability of the air conditioner, reduces maintenance frequency, and maintains good air treatment performance.

[0131] Specifically, during the heating process of the air conditioning device, the filter structure 20 switches from the second filtering state to the first filtering state, and uses the heat generated by the evaporator 10 and the wind force of the high-speed windshield to deeply dry the filter structure 20 to ensure that it is dry and clean, thereby improving the self-maintenance capability and long-term operation reliability of the air conditioning device.

[0132] In this embodiment, the cleaning method further includes: making the first absolute temperature difference value corresponding to the temperature difference between the tube temperature of the evaporator 10 and the dew point temperature greater than or equal to 3°C. By controlling the temperature difference between the tube temperature of the evaporator 10 and the dew point temperature, a sufficient amount of condensed water is ensured to be formed, thereby improving the cleaning effect. In this way, the self-cleaning ability of the air-conditioning device is improved, the maintenance frequency is reduced, and a good air treatment effect is also maintained. In the cleaning mode, the air-conditioning device controls the tube temperature of the evaporator 10 to be lower than the dew point temperature by more than 3°C, so as to promote the rapid condensation of moisture in the air and form a large amount of condensed water, thereby improving the cleaning effect and ensuring the cleanliness and effectiveness of the filter structure 20. In addition, the setting of the above-mentioned temperature difference value is combined with the fact that at least part of the filter structure 20 is made of metal material, which facilitates the rapid formation of condensed water.

[0133] Specifically, when the filter 232 is activated for cleaning, the filter structure 20 is in the first filtering state. In the first filtering state, the filter structure 20 is closer to the evaporator 10. At this time, the evaporator 10 is cooled, the pipe temperature is >3° lower than the dew point temperature, and the air conditioner uses a low windshield. Since the top handle of the support frame 231 (the operating portion 24 includes the handle) is made of metal, condensation will form on the surface, and the condensed water will flow downward. After the time exceeds 10 minutes, the filter structure 20 is adjusted to the second filtering state and is in a vertical extension direction. At this time, the condensed water will remain in the lower part of the filter structure 20, and then flow to the water receiving tray 50 and pass through the drain pipe connected to the water receiving tray 50 to achieve water cleaning of the filter 232. After the dripping is completed, the filter structure 20 returns to the position of the first filtering state, and the air conditioner turns on the heating, increases the air conditioner fan speed to the medium windshield, and dries the filter 232. After completion, the filter 232 is turned off, and the complete cleaning process of the filter 232 is completed.

[0134] Specifically, during the cleaning process of the filter screen 232, the cleaning process can also be combined with the shaking of the motor 43. Specifically, since the guide arc groove 422 has a first limit end and a second limit end respectively located at both ends of the guide arc groove 422, when the crank 41 rotates to abut the first limit end and the second limit end, the corresponding filter structure 20 is at a first limit rotation angle and a second limit rotation angle respectively. In this way, when abutting the first limit end and the second limit end respectively, the motor 43 will also shake due to the limiting effect, thereby driving the crank 41 to shake, thereby causing the entire filter structure 20 to shake as a whole, thereby facilitating better dropping of condensed water on the filter structure 20.

[0135] In this embodiment, the control method also includes a method for regulating the temperature of the indoor space in which the air conditioning device is located using the air conditioning device. The regulation method includes: starting the air conditioning device, obtaining a second absolute temperature difference value corresponding to the temperature difference between the indoor environment in which the air conditioning device is located and the set temperature and / or an air mass fraction corresponding to the indoor environment; and adjusting the filter structure 20 based on the second absolute temperature difference value and / or the air mass fraction corresponding to the indoor environment. This facilitates effectively finding an optimal balance between filtering effect and airflow resistance, thereby ensuring smooth airflow while also maintaining filtering effect and improving air quality.

[0136] Specifically, the filter structure 20 is adjusted based on the second absolute temperature difference and / or the air quality score corresponding to the indoor environment, including: controlling the filter structure 20 to switch to the first filtering state or the second filtering state based on the second absolute temperature difference, and ensuring that the second absolute temperature difference corresponding to the first filtering state is less than the second absolute temperature difference corresponding to the second filtering 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 and user comfort of the air conditioning system, reduces energy consumption, and also lowers maintenance costs.

[0137] Specifically, the filter structure 20 is adjusted based on the second absolute temperature difference and / or the air quality score corresponding to the indoor environment, including: when the quality score corresponding to the indoor environment is greater than or equal to a preset quality score value, the filter structure 20 is controlled to be in the second filtering state. In this way, when the air quality of the indoor environment is relatively good, the smoothness of the air flow can be ensured. Specifically, the air quality score corresponding to the air quality of the indoor environment can be obtained by conventionally combining comprehensive values such as PM value and carbon dioxide content. When the air quality score corresponding to the air quality of the indoor environment is greater than or equal to the preset quality score value, the air quality of the corresponding indoor environment is relatively good.

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

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

[0140] It should be noted that “a windshield larger than the first operating windshield” means that the wind speed corresponding to the windshield larger than the first operating windshield is larger 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, and the resistance to air flow at the air outlet side 12 is reduced.

[0142] Specifically, the first preset temperature difference value may be set to 1°C.

[0143] In this way, when the air conditioning device is running, the state of the filter structure 20 and the level of the operating windshield are automatically adjusted according to the real-time monitoring of the indoor temperature and the set temperature 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, where 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 damper; 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 damper; wherein the second operating damper is greater than the third operating damper. By setting multiple temperature difference thresholds and operating damper levels, refined control of the filter structure 20 is achieved to adapt to temperature regulation and air purification requirements under different temperature difference conditions. This improves the operating efficiency and user comfort of the air conditioning device, reduces energy consumption, and also reduces maintenance costs and extends the life of the equipment. Specifically, when the air conditioning device is in operation, it automatically adjusts the communication 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 to achieve optimal temperature regulation and air purification effects, 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 may be set to 8° C. to 15° C. (including endpoint values 8° C. and 15° C.).

[0147] Specifically, the adjustment method also includes: obtaining the operating time of the air conditioning device; if the operating time is within the sleep time period, controlling the filter structure 20 to be in a first filtering state; if the operating time is within the non-sleep time period, adjusting the filter structure 20 based on the second absolute temperature difference and / or the air quality score corresponding to the indoor environment. By monitoring the operating time of the air conditioning device, intelligently determining whether it is in the sleep time period and combining the determination of the air quality score, 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 noise during nighttime operation, and also maintains good air treatment effects.

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

[0149] Specifically, when the air conditioning device is operating at night, it automatically adjusts the filter structure 20 to the first filter state to reduce operating noise while maintaining a good air purification effect, ensuring the comfort and health of the user when resting 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 filtering state, that is, a connecting gap 32 is provided between the filter structure 20 and the evaporator 10, and the speed of the fan of the air conditioning device is reduced, the resistance is reduced, and the operating efficiency of the air conditioning device and the user experience are significantly improved.

[0151] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: they solve the technical problems of low cleaning efficiency and difficult maintenance of the filter structure on the air outlet side; and improve the cleaning efficiency of the filter structure. Furthermore, the cleaning method of the present application is adaptable to the complex internal structure of an air conditioner and simplifies the assembly and disassembly and cleaning process of the air conditioner's fan blades and fan chamber, avoiding the risk of water ingress or damage to components, reducing maintenance costs and safety hazards. The present invention solves the technical problem of a single air supply mode and limited operating performance of an air conditioner, while also achieving a technical solution that provides flexible air supply control and reduces noise. The air supply state can be intelligently adjusted based on factors such as ambient temperature and air quality, which can lead to excessive wind blocking by the filter structure in certain situations, affecting the air conditioner's operating efficiency and air supply effect. This improves the environmental adaptability of the filter structure, enabling efficient and energy-saving operation of the air conditioner. The structure of the filter structure's movement mechanism is simple, low-cost, and highly efficient, while also occupying a small space. This optimizes the overall design and installation layout of the air conditioner, ensuring functional optimization and improved performance of the air conditioner.

[0152] A new motion structure is used to optimize the air outlet and comfort of traditional air conditioners. A setting with guide grooves and guide arc grooves is adopted to realize the movement of the filter structure in a limited space while achieving the control position with adjustable spacing. Combined with the control of the evaporator, fan and environment, it can realize the cleaning of the filter and improve the comfort effect of air conditioning use.
