[0059] As shown in Figures 1 to 6 The indoor unit of the air conditioner according to the first embodiment of the present application comprises an indoor unit body 1 and a dust shielding assembly.

[0060] The top end of the indoor unit body 1 is provided with an air inlet 11, and the indoor unit body 1 is further provided with an air inlet filter arranged opposite to the air inlet 11. A visible window 13 for observing the air inlet filter is formed in an indoor unit panel 12 of the indoor unit body 1, and a splicing plate 2 is detachably installed in the visible window 13.

[0061] The dust shielding assembly is rotatably connected with the indoor unit body 1 to be adapted to switch between a first position and a second position. In the first position, the dust shielding assembly is arranged opposite to the air inlet 11 and used for covering the air inlet 11. In the second position, the dust shielding assembly is arranged opposite to the visible window 13 and used for covering the visible window 13.

[0062] It can be understood that for the indoor unit of the air conditioner of the present application, the air inlet 11 is located at the top of the indoor unit body 1 for introducing external air. The air inlet filter is installed in the indoor unit body 1 and is arranged opposite to the air inlet 11 for filtering the incoming air. The visible window 13 is provided on the panel of the indoor unit body 1, and the user can observe the state of the air inlet filter through the visible window 13.

[0063] The indoor unit of the present application mainly has two groups of functional components, namely the splicing plate 2 and the dust-proof shielding assembly. The splicing plate 2 is detachably installed in the visible window 13, and the user can detach the splicing plate 2 to observe the cleaning process of the air inlet filter. The dust-proof shielding assembly is connected to the indoor unit body 1 through a rotatable connecting mechanism and can be switched between a first position and a second position. In the first position, the dust-proof shielding assembly is arranged opposite to the air inlet 11 for covering the air inlet 11 to prevent dust from entering. In the second position, the dust-proof shielding assembly is arranged opposite to the visible window 13 for covering the visible window 13, but in the second position, a certain gap is left between the visible window 13 and the dust-proof shielding assembly to ensure air inlet.

[0064] The specific working principle of the indoor unit of the present application is as follows: after the indoor unit body 1 is started, the current working mode of the indoor unit body 1 is determined, for example, Figures 1 to 3 If the current indoor unit body 1 is in the cleaning mode for automatically cleaning the air inlet filter, the splicing plate 2 can be detached from the visible window 13 to expose the air inlet filter inside the indoor unit body 1 to the user's field of view through the visible window 13, so that the user can clearly observe the cleaning process of the air inlet filter. At this time, the dust-proof shielding assembly is always in the first position, that is, the dust-proof shielding assembly is located above the air inlet 11 and shields the air inlet 11. In this way, on the one hand, the visible window 13 is not shielded, thereby facilitating the user to observe the cleaning process, and on the other hand, the dust-proof effect of the air inlet 11 can be achieved.

[0065] As shown in Figures 4 to 6 If the current indoor unit body 1 is in the working mode requiring air inlet, such as refrigeration, heating, defrosting, dehumidification, etc., the dust-proof shielding assembly will be rotated from the first position to the second position, that is, the dust-proof shielding assembly is rotated to the position corresponding to the visible window 13 and covers the visible window 13. It needs to be explained that in the second position, the visible window 13 is not completely closed by the dust-proof shielding assembly, but leaves a certain gap distance in the horizontal direction. Further, since air inlet can also be achieved at the position of the visible window 13, the gap left between the visible window 13 and the dust-proof shielding assembly can also achieve the air inlet function, thereby further improving the air inlet volume of the indoor unit and improving the working efficiency and performance of the air conditioner.

[0066] It can be understood that when the dustproof shielding assembly is rotated to the second position, on the one hand, the air inlet 11 is not affected by the dustproof shielding assembly, that is, the above structure can ensure the normal air inlet of the air inlet 11; on the other hand, the dustproof shielding assembly shields the visible window 13, thereby avoiding the exposure of the visible window 13 to cause the indoor unit appearance to be not beautiful, improving the beauty of the indoor unit to improve the user's use experience. In addition, the gap left between the visible window 13 and the dustproof shielding assembly can also realize the air inlet function, thereby further improving the air inlet amount of the indoor unit, and further improving the working efficiency and working performance of the air conditioner.

[0067] In summary, in the cleaning mode, the dustproof shielding assembly shields the air inlet 11, and the visible window 13 is exposed, which is convenient for the user to observe the cleaning process of the air inlet filter. In the conventional working mode, the dustproof shielding assembly shields the visible window 13, but a certain gap is left between the visible window 13 and the dustproof shielding assembly, which ensures the air inlet while improving the appearance.

[0068] This design combines the dual functions of dust prevention and observation, which not only ensures the cleanliness and working efficiency of the air conditioner, but also provides a way for the user to intuitively observe the cleaning process of the filter screen.

[0069] In the related art, the air inlet of the existing air conditioner mainly relies on the dust screen to shield the dust in the air, and the dust screen needs to be cleaned regularly during long-term use. At the same time, the dust screen cannot completely shield the dust, and the excess dust will accumulate in the evaporator fins, reducing the energy conversion efficiency of the air conditioner and shortening the service life of the air conditioner. In addition, the current air conditioner does not have a special dust removal function design, and generally monitors PM2.5, but cannot avoid the accumulation of large-particle dust. The existing air conditioner sets the air inlet as a louver structure, which rotates the louver through a motor to ensure the opening and closing of the air inlet.

[0070] Therefore, in order to solve the technical defects existing in the above related art, the present application provides an indoor unit of an air conditioner, which is intelligently controlled to open and close the air inlet 11 through a new dustproof + filter screen cleaning visualization design, and the user can intuitively feel the cleaning strength of the filter screen according to whether to watch the filter screen cleaning process.

[0071] Further, the present application has at least the following advantages compared with the related art.

[0072] (1) Dustproof design

[0073] High dustproof: by automatically shielding the air inlet 11 when the air conditioner is not used, dust is effectively prevented from entering the interior of the air conditioner, the evaporator is protected from dust, and the service life of the air conditioner is prolonged.

[0074] Intelligent control: The dustproof shielding assembly can automatically switch positions according to the working state of the air conditioner, intelligently control the opening and closing of the air inlet 11, and does not need frequent manual intervention.

[0075] (2) Filter screen cleaning visualization

[0076] Direct observation: Users can disassemble the spliced plate 2 in the visual window 13 and directly observe the cleaning process of the air inlet filter (filter screen), increasing the user's confidence in the cleaning state of the filter screen.

[0077] Convenient maintenance: The panel is designed in a spliced structure, easy to disassemble, and convenient for users to perform daily cleaning and maintenance work.

[0078] (3) Structure optimization

[0079] Increase air intake: When the air conditioner is running, the dustproof shielding assembly is inclined outward by 10°, expanding the air intake area and increasing the air intake of the air conditioner, improving the working efficiency of the air conditioner.

[0080] Aesthetics: In the normal working mode, the dustproof shielding assembly shields the visual window 13, but there is a certain gap between the visual window 13 and the dustproof shielding assembly, which does not affect the air intake and maintains the neat appearance of the air conditioner.

[0081] (4) User experience

[0082] Enhance confidence: Users can directly observe the cleaning process of the filter screen, increasing the user's trust in the cleanliness of the air conditioner.

[0083] Easy operation: The spliced design of the panel and the automatic operation of the dustproof shielding assembly simplify the user's use process.

[0084] (5) Technical innovation

[0085] Intelligent control: The dustproof shielding assembly automatically controls the position according to the working state of the air conditioner, ensuring the best performance of the air conditioner in different working modes.

[0086] Adjust the air intake: By adjusting the inclination angle of the dustproof shielding assembly, the air intake can be increased as needed, improving the working efficiency of the air conditioner.

[0087] In summary, the intelligent dustproof shielding assembly and the visual filter screen cleaning design not only solve the dust problem of traditional air conditioners, but also improve the user experience and the convenience of cleaning and maintaining the air conditioner, thereby improving the overall performance of the air conditioner and the user's satisfaction.

[0088] For example Figure 1As shown, according to some embodiments of the present application, the dustproof shielding assembly comprises a first motor 3, a first connecting piece 4 and a dustproof device. The body of the first motor 3 is fixed to the inner machine body 1, and the two ends of the first connecting piece 4 are respectively fixed to the transmission end of the first motor 3 and the dustproof device; the first motor 3 is used to drive the dustproof device to rotate between the air outlet and the visual window 13.

[0089] As shown in Figure 1 Further, the number of the first motor 3 and the first connecting piece 4 is both two, the bodies of the two motors are respectively fixed to the left and right side walls of the inner machine body 1, and the driving ends of the two motors are both perpendicular to the left and right side walls of the inner machine body 1.

[0090] One end of the two first connecting pieces 4 is respectively in transmission connection with the driving end of the two motors, and the other end of the two first connecting pieces 4 is respectively fixed to the left and right ends of the dustproof device.

[0091] In the above embodiment, the dustproof shielding assembly is composed as follows: two first motors 3, the bodies of which are respectively fixed to the left and right side walls of the inner machine body 1, and the driving ends of the motors are perpendicular to the side walls of the inner machine body 1. There are also two first connecting pieces 4, one end of which is respectively in transmission connection with the driving end of the two first motors 3, and the other end of which is fixed to the left and right ends of the dustproof device. The dustproof device is composed of a dustproof panel 5 and a fixed support 6, and the position between the dustproof panel 5 and the fixed support 6 can be adjusted by a distance adjusting piece 7. For example, the first connecting piece 4 can be a connecting rod.

[0092] The general working principle of the dustproof shielding assembly is as follows: the first motor 3 drives the dustproof device to rotate between the air outlet and the visual window 13, so as to realize the shielding of the air inlet 11 or the shielding of the visual window 13. The first connecting piece 4 serves as a transmission component to transmit the power of the first motor 3 to the dustproof device, so that the dustproof device can move along a predetermined track.

[0093] In this way, through the two first motors 3 and the two first connecting pieces 4, the dustproof shielding assembly can smoothly rotate between the air outlet and the visual window 13. In different working modes, the position change of the dustproof shielding assembly realizes the dustproof of the air inlet 11 and the shielding of the visual window 13, while ensuring good air inlet performance. This design not only improves the dustproof ability of the air conditioner, but also increases the user's confidence in use through the visual filter cleaning process.

[0094] As shown in Figure 5 and Figure 6 According to some embodiments of the present application, the first connecting piece 4 is fixed to one end of the dustproof device, so that in the second position, the upper end of the dustproof panel 5 is fixedly connected with the first connecting piece 4, and the lower end of the dustproof panel 5 abuts against the inner machine panel 12.

[0095] In the present embodiment, when the dust shielding assembly is in the second position, it means that it has been rotated to the position of shielding the visual window 13. In this position, the upper end of the dust panel 5 is connected with the motor or other driving components through the first connecting member 4, so as to maintain the stability of the dust panel 5. The lower end of the dust panel 5 directly abuts against the inner machine panel 12, which helps to ensure the stability of the dust panel 5 in the second position and can reduce any possible shaking or vibration.

[0096] It can be understood that in the second position, the main function of the dust shielding assembly is to shield the visual window 13 to prevent dust from entering the inner machine body 1 through the visual window 13. At the same time, a certain gap is left between the visual window 13 and the dust shielding assembly to ensure that a certain degree of air inlet function can be achieved even in the case that the dust shielding assembly shields the visual window 13.

[0097] In this way, in the second position, the dust shielding assembly fixes the upper end of the dust panel 5 through the first connecting member 4, and the lower end of the dust panel 5 abuts against the inner machine panel 12 to achieve effective shielding of the visual window 13 and maintain the stability of the dust panel 5 and the air inlet function of the visual window 13.

[0098] As shown in Figure 5 and Figure 6 , in some specific embodiments of the present application, the dustproof device comprises a dust panel 5 and a fixed support 6, and a distance adjusting member 7 is connected between the dust panel 5 and the fixed support 6, which is used to adjust the distance between the dust panel 5 and the fixed support 6.

[0099] In the second position, the lower end of the dust panel 5 abuts against the inner machine panel 12, and the distance between the upper end of the dust panel 5 and the fixed support 6 is adjustable through the distance adjusting member 7, so that the included angle between the dust panel 5 and the inner machine panel 12 is adjustable.

[0100] In the present embodiment, the dustproof device is constituted as follows: the dust panel 5 is directly used to shield the visual window 13 or the air inlet 11. The fixed support 6 is used to support the dust panel 5 and is connected with the dust panel 5 through the distance adjusting member 7. The distance adjusting member 7 is used to adjust the distance between the dust panel 5 and the fixed support 6, and further adjust the included angle between the dust panel 5 and the inner machine panel 12.

[0101] The working principle of the dustproof device is as follows: when the dustproof shielding assembly is in the second position, the lower end of the dustproof panel 5 abuts against the inner machine panel 12, and the upper end of the dustproof panel 5 is connected with the fixed support 6 through the distance adjusting piece 7. By adjusting the distance adjusting piece 7, the distance between the dustproof panel 5 and the fixed support 6 can be changed, thereby changing the included angle between the dustproof panel 5 and the inner machine panel 12. This adjustment mechanism allows the dustproof panel 5 to be inclined at a certain angle to adapt to different working requirements. Among them, the distance adjusting piece 7 can have different implementation forms, such as elastic members (such as springs), telescopic members, or sliding rods, etc.

[0102] It can be understood that the application scenario of the above structure is as follows: in the second position, the dustproof panel 5 shields the visible window 13, but a certain gap is left between the visible window 13 and the dustproof shielding assembly to realize the air inlet function. By adjusting the included angle between the dustproof panel 5 and the inner machine panel 12, the air inlet efficiency can be optimized or other special requirements can be met, such as increasing the air inlet amount or improving air flow.

[0103] In summary, the dustproof panel 5 and the fixed support 6 are connected through the distance adjusting piece 7, which can adjust the included angle between the dustproof panel 5 and the inner machine panel 12. This design not only ensures the air inlet efficiency in different working modes, but also improves the flexibility and practicality of the air conditioner.

[0104] For example, the distance adjusting piece 7 includes an elastic member, and the two ends of the elastic member are fixed on the fixed support 6 and the dustproof panel 5 respectively. It can be understood that by the natural stretching and contracting characteristics of the elastic member, the distance between the dustproof panel 5 and the fixed support 6 can be adjusted, thereby adjusting the included angle between the dustproof panel 5 and the inner machine panel 12. In this way, when the position of the dustproof panel 5 needs to be adjusted, the elastic member will be stretched or compressed accordingly, thereby changing the distance between the dustproof panel 5 and the fixed support 6.

[0105] For another example, the distance adjusting piece 7 includes a telescopic member, and the two ends of the telescopic member are rotatably installed on the fixed support 6 and the dustproof panel 5 respectively and are telescopically arranged. It can be understood that by the telescopic characteristics of the telescopic member, the distance between the dustproof panel 5 and the fixed support 6 can be adjusted, thereby adjusting the included angle between the dustproof panel 5 and the inner machine panel 12. In this way, the length of the telescopic member is adjusted by mechanical or electric means, thereby changing the distance between the dustproof panel 5 and the fixed support 6.

[0106] For another example, the distance adjusting member 7 comprises a sliding rod, the dustproof panel 5 and the fixed support 6 are respectively provided with a first sliding groove and a second sliding groove extending along the length direction thereof, and the two ends of the sliding rod are respectively matched in the first sliding groove and the second sliding groove. It can be understood that the distance between the dustproof panel 5 and the fixed support 6 can be adjusted by the sliding of the sliding rod in the sliding groove, and then the included angle between the dustproof panel 5 and the inner machine panel 12 can be adjusted. In this way, the position change of the sliding rod in the sliding groove will cause the distance change between the dustproof panel 5 and the fixed support 6.

[0107] For another example, the distance adjusting member 7 comprises a second motor and a second connecting member, the body of the second motor is fixed on the fixed support 6, and the driving end of the second motor is in transmission connection with one end of the second connecting member, the dustproof panel 5 is provided with a third sliding groove extending along the length direction thereof, and the other end of the second connecting member is matched in the third sliding groove.

[0108] It can be understood that the distance between the dustproof panel 5 and the fixed support 6 can be adjusted by the driving of the second motor, and then the included angle between the dustproof panel 5 and the inner machine panel 12 can be adjusted.

[0109] In this way, the second motor drives the second connecting member to move in the third sliding groove, so as to change the distance between the dustproof panel 5 and the fixed support 6.

[0110] For another example, the distance adjusting member 7 comprises a driving air cylinder and a second connecting member, the body of the driving air cylinder is fixed on the fixed support 6, and the driving end of the driving air cylinder is in transmission connection with one end of the second connecting member, and the other end of the second connecting member is in rotatable connection with the dustproof panel 5.

[0111] It can be understood that the distance between the dustproof panel 5 and the fixed support 6 can be adjusted by the extension and contraction of the driving air cylinder, and then the included angle between the dustproof panel 5 and the inner machine panel 12 can be adjusted.

[0112] In this way, the extension and contraction of the driving air cylinder will cause the position change of the second connecting member, so as to change the distance between the dustproof panel 5 and the fixed support 6.

[0113] In summary, the above five kinds of implementation manners can effectively adjust the distance between the dustproof panel 5 and the fixed support 6, and then adjust the included angle between the dustproof panel 5 and the inner machine panel 12. Each manner has its characteristics, and the appropriate implementation manner can be selected according to the specific application requirement and technical condition.

[0114] As shown in FIG. 1, Figure 3 According to some embodiments of the present application, in the first position, the dustproof device is parallel to the air inlet 11, and the length of the first connecting member 4 is adjustable, so that the distance between the dustproof device and the air inlet 11 is adjustable.

[0115] In this embodiment, when the dustproof device is in the first position, it is parallel to the air inlet 11 and used to shield the air inlet 11 to prevent dust from entering. The first connecting piece 4 is fixed at one end of the dustproof device and connected to the driving end of the first motor 3 for power transmission and support of the dustproof device. The length of the first connecting piece 4 is adjustable, which means the length of the first connecting piece 4 can be adjusted as needed to change the distance between the dustproof device and the air inlet 11.

[0116] The working principle is as follows: when the dustproof device is in the first position, it shields the air inlet 11 to prevent dust from entering the air conditioner. By adjusting the length of the first connecting piece 4, the distance between the dustproof device and the air inlet 11 can be changed. This design makes the position of the dustproof device more flexible, and the distance between the dustproof device and the air inlet 11 can be adjusted according to different needs to achieve the best dustproof effect.

[0117] Specifically, the first connecting piece 4 can realize the function of adjustable length in various ways, such as a telescopic rod: using a telescopic rod as the first connecting piece 4, the position of the dustproof device is changed by adjusting the length of the telescopic rod. For example, a sliding mechanism: a sliding groove is provided on the fixed support 6, one end of the first connecting piece 4 cooperates with the sliding groove, and the length of the first connecting piece 4 is adjusted by sliding. For example, screw adjustment: using a threaded first connecting piece 4, the length of the first connecting piece 4 is adjusted by rotating.

[0118] In this way, by adjusting the distance between the dustproof device and the air inlet 11, dust can be prevented from entering more effectively, and the interior of the air conditioner is protected from pollution. And by adjusting the length of the first connecting piece 4, the position of the dustproof device is more flexible, and the dustproof effect can be adjusted according to the actual situation.

[0119] In summary, when the dustproof device is in the first position, it is parallel to the air inlet 11, and the distance between the dustproof device and the air inlet 11 is changed by adjusting the length of the adjustable first connecting piece 4. This design enhances the flexibility of the dustproof shielding assembly, which can adjust the dustproof effect according to different needs, thereby better protecting the interior of the air conditioner from dust pollution.

[0120] The control method and control device of the indoor unit of the air conditioner and the air conditioner are described below with reference to the accompanying drawings. Before the embodiments of the present application are described in detail, the entire application scenario is described. The control method and control device of the indoor unit of the air conditioner, electronic equipment and computer readable storage medium of the embodiments of the present application can be applied to the local indoor unit of the air conditioner, the cloud platform in the Internet field, or the cloud platform in other types of Internet fields, or can also be applied to third-party devices. The third-party devices can include mobile phones, tablet computers, notebooks, vehicle-mounted computers and other smart terminals of various types.

[0121] The following will be described only by taking the control method of the indoor unit of the air conditioner as an example, and it should be understood that the control method of the embodiments of the present application can also be applied to the cloud platform and the third-party device.

[0122] As shown in the control method of the indoor unit of the air conditioner based on the first aspect of the present application, according to the second aspect of the present application, the method comprises: Figure 7

[0123] Step S1, obtaining the working state of the indoor unit body 1;

[0124] Step S2, in the case that the indoor unit body 1 is not started, controlling the dustproof shielding assembly to be in the first position; or in the case that the indoor unit body 1 is started and the splicing plate 2 is detached from the visible window 13, controlling the dustproof shielding assembly to be in the second position.

[0125] According to the control method of the indoor unit of the air conditioner of the present application, the specific working principle and process are as follows: judging the current working mode of the indoor unit body 1. And controlling the position of the dustproof shielding assembly according to the working mode.

[0126] In the cleaning mode: when the indoor unit body 1 is in the cleaning mode of automatically cleaning the air inlet filter, in order to facilitate the user to observe the cleaning process, the splicing plate 2 can be detached from the visible window 13. The dustproof shielding assembly is always in the first position, i.e. shielding the air inlet 11, to realize the dustproof effect of the air inlet 11.

[0127] In the normal working mode (such as refrigeration, heating, defrosting, dehumidifying, etc.): when the indoor unit body 1 is in the working mode that needs air inlet, the dustproof shielding assembly will rotate from the first position to the second position, i.e. shielding the visible window 13. In the second position, there is a certain gap distance between the visible window 13 and the dustproof shielding assembly to realize the air inlet function.

[0128] Further, the working principle of the method is explained as follows: (1) cleaning mode: the user can detach the splicing plate 2 in the visible window 13 to observe the cleaning process of the air inlet filter. The dustproof shielding assembly is always in the first position, i.e. shielding the air inlet 11, to prevent dust from entering. In this way, the cleanliness of the air inlet 11 is ensured, and the user can easily observe the cleaning process.

[0129] (2) normal working mode: the dustproof shielding assembly rotates from the first position to the second position, i.e. shielding the visible window 13. There is a certain gap between the visible window 13 and the dustproof shielding assembly to ensure the air inlet function. The air inlet 11 is not shielded, ensuring the normal air inlet amount. The gap between the visible window 13 and the dustproof shielding assembly can also realize air inlet, thereby improving the total air inlet amount and further improving the working efficiency of the air conditioner. ​

[0130] Further, the specific control logic is as follows: when the inner machine body 1 is in the cleaning mode, the dustproof shielding assembly shields the air inlet 11, and the visible window 13 is exposed, facilitating the user to observe the cleaning process. When the inner machine body 1 is in the normal working mode, the dustproof shielding assembly shields the visible window 13, but there is a certain gap between the visible window 13 and the dustproof shielding assembly, which ensures the air inlet and improves the aesthetics.

[0131] In summary, the control method of the present application intelligently judges the working mode of the inner machine body 1, automatically controls the position of the dustproof shielding assembly, ensures the dustproof effect of the air inlet 11, and provides a user-friendly observation experience. Moreover, by adjusting the position of the dustproof shielding assembly in different working modes, efficient air inlet and aesthetic effect are achieved, improving the working efficiency of the air conditioner and the user experience.

[0132] As shown in FIG. 1, according to some embodiments of the present application, after the step of controlling the dustproof shielding assembly to be in the second position, the method further comprises: Figure 6

[0133] determining that the air inlet 11 has an air inlet action, and adjusting the distance adjusting part 7 to make the dustproof panel 5 away from the fixed support 6.

[0134] In this embodiment, when the inner machine body 1 is started and in the working mode that needs air inlet (such as refrigeration, heating, defrosting, dehumidifying, etc.), and the user has disassembled the splicing plate 2 in the visible window 13 in order to observe the cleaning process of the air inlet filter. The system needs to further determine whether the air inlet 11 has started the air inlet action. If the air inlet 11 has started the air inlet action, the distance adjusting part 7 needs to be adjusted to make the dustproof panel 5 away from the fixed support 6. This is done to further increase the air inlet area of the air inlet 11, thereby increasing the air inlet amount and improving the working efficiency of the air conditioner.

[0135] For example, the distance adjusting part 7 can be an elastic part, a telescopic part, a sliding rod, a second motor and a second connecting part, or a driving air cylinder and a second connecting part. By adjusting the distance between the dustproof panel 5 and the fixed support 6 through these distance adjusting parts 7, the included angle between the dustproof panel 5 and the inner machine panel 12 is changed, and the air inlet area is increased.

[0136] In this way, the control method of the present application intelligently judges the working mode of the inner machine body 1, and automatically adjusts the position of the dustproof shielding assembly and the distance between the dustproof panel 5 and the fixed support 6 according to the air inlet condition. This not only ensures the dustproof effect of the air inlet 11, but also improves the air inlet efficiency by adjusting the position of the dustproof panel 5, thereby improving the working efficiency of the air conditioner and the user experience.
