Description

Technical Field

[0001] This application relates to the field of air conditioner technology, for example to a panel assembly and an air conditioner. Background Technology

[0002] Currently, air conditioners typically have an air intake grille installed at the air inlet. This grille effectively blocks large particles of impurities in the airflow, such as dust, catkins, fallen leaves, and insects. Furthermore, when the grille is located at the air inlet, it also prevents these impurities from entering the air conditioner's interior, avoiding duct blockage, poor heat dissipation, and even damage to critical components such as the fan and compressor.

[0003] In related technologies, air intake grilles are usually fixed in place, for example, by using screws or other fasteners to fix them to the housing of the air conditioner.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, while screws and other methods of connection can ensure the stability of the air intake grille, they have some shortcomings in practical use. The disassembly process for fixed-installation air intake grilles is cumbersome, requiring tools to remove each screw individually. This not only increases maintenance costs for users but also reduces maintenance efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0045] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0047] Combination Figures 1 to 22 As shown, this disclosure provides an air conditioner, which includes an air conditioner body and a panel assembly. The air conditioner body includes a housing, a heat exchanger, and a fan. The housing defines an air outlet duct, and the heat exchanger and fan are located within the duct. The panel assembly includes a panel 10, which has an air outlet 121 and a plurality of air inlets 111. Two of the air inlets 111 are located on either side of the air outlet 121, and the air inlets 111 and the air outlet 121 are spaced apart along the length of the panel 10. The length and width directions of the panel, air inlets, air outlets, air inlet frame, and air outlet frame are as follows. Figure 1 As shown.

[0048] In this embodiment, air inlets 111 are provided on both sides of the air outlet 121, and the air inlets 111 and air outlet 121 are arranged along the length direction of the panel 10. This makes the arrangement of the air inlets 111 and air outlet 121 more compact, thereby reducing the space occupied by the panel 10 and improving the structural compactness of the panel 10. Moreover, the air outlet 121 and air inlets 111 are spaced apart, so that there is a gap between the air inlets 111 and air outlet 121 to avoid the airflow from the air inlets 111 and air outlet 121 from being turbulent.

[0049] Alternatively, the air conditioner can be a kitchen air conditioner. This allows for a more efficient arrangement of air intake and exhaust within the limited space of the kitchen, ensuring both adequate airflow.

[0050] It's understandable: air conditioners can also be placed in other areas, such as the living room or bedroom.

[0051] Optionally, such as Figure 1 As shown, the distance between the air inlet 111 and the air outlet 121 is greater than 200mm and less than 1000mm. The distance between the air inlet 111 and the air outlet 121 is as follows: Figure 1 As shown in L1 and L2.

[0052] In this embodiment, when the distance between the air inlet 111 and the air outlet 121 is less than 200mm, the air inlet 111 and the air outlet 121 are too close, which can easily lead to turbulent airflow. When the distance between the air inlet 111 and the air outlet 121 is greater than 1000mm, the distance between the air inlet 111 and the air outlet 121 is too far, which can lead to excessive airflow resistance or untimely heat transfer. Therefore, setting the distance between the air inlet 111 and the air outlet 121 within the above-mentioned range ensures sufficient space for airflow and heat exchange while avoiding the problems of excessive airflow resistance or untimely heat transfer caused by excessive distance. This not only improves the cooling or heating effect of the air conditioner but also more effectively removes oil fumes and odors from the kitchen, providing users with a more comfortable and healthy kitchen environment.

[0053] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the length directions of the air inlet 111 and the air outlet 121 are both linearly spaced along the length direction of the panel 10.

[0054] In this embodiment of the present disclosure, when the air inlet 111 and the air outlet 121 are linearly spaced along the length of the panel 10, the air inlet 111 and the air outlet 121 are arranged in a narrow and long shape on the panel 10. The air flow path inside the panel 10 is smoother, which can further improve the air flow efficiency, reduce air resistance, and thus improve the heat exchange performance of the air conditioner.

[0055] Optionally, when the length directions of the air inlet 111 and the air outlet 121 are both linearly spaced along the length direction of the panel 10, the distance between the air inlet 111 and the air outlet 121 is greater than or equal to 200mm and less than or equal to 400mm.

[0056] In this embodiment, when the length directions of the air inlet 111 and the air outlet 121 are both linearly spaced along the length direction of the panel 10, the air outlet 111 and the air outlet 121 have a large air outlet range along the length direction of the panel 10. Therefore, the distance between the air inlet 111 and the air outlet 121 is between 200mm and 400mm. This ensures a more compact airflow within the panel 10, increases the air circulation speed, and thus more quickly removes fumes and odors. It also helps to quickly regulate the temperature in the kitchen. For example, the distance between the air inlet 111 and the air outlet 121 is 200mm, 250mm, 280mm, 300mm, 310mm, 350mm, 380mm, 400mm, etc.

[0057] In some alternative embodiments, the length directions of the air inlet 111 and the air outlet 121 are both arranged parallel to the length direction of the panel 10 (not shown in the figure).

[0058] In this embodiment, when the length directions of the air inlet 111 and the air outlet 121 are both parallel to the length direction of the panel 10, that is, the lengths of the air inlet 111 and the air outlet 121 extend along the width direction of the panel 10, increasing the air intake and exhaust volume in the width direction of the panel 10. This layout helps to achieve a more uniform air distribution, making the temperature regulation in the kitchen more uniform, avoiding localized excessively high or low temperatures, and further improving the user experience.

[0059] Optionally, when the length directions of the air inlet 111 and the air outlet 121 are both parallel to the length direction of the panel 10, the distance between the air inlet 111 and the air outlet 121 is greater than or equal to 800mm and less than or equal to 1000mm.

[0060] In this embodiment, when both the length direction of the air inlet 111 and the length direction of the air outlet 121 are parallel to the length direction of the panel 10, the distance between the air inlet 111 and the air outlet 121 is relatively large. This ensures sufficient flow space for the airflow within the panel 10, resulting in smoother airflow and improved heat exchange efficiency. It also helps reduce noise generated by airflow, providing a quieter kitchen environment for the user. For example, the distance between the air inlet 111 and the air outlet 121 is 800mm, 850mm, 890mm, 900mm, 950mm, 960mm, 980mm, 1000mm, etc.

[0061] Optionally, the air inlet 111 and air outlet 121 are equidistant along the length of the panel 10. This results in a more uniform air distribution within the panel 10, further improving air circulation efficiency. Furthermore, the equidistant arrangement facilitates more uniform temperature regulation, preventing excessive localized temperature differences caused by uneven air distribution. Simultaneously, the equidistant arrangement makes the panel assembly structure more symmetrical and aesthetically pleasing, enhancing the overall appearance of the product. It can be understood that the air inlet and outlet can also be unequally spaced, such as... Figure 1 As shown, L1 and L2 are different.

[0062] Optionally, the plurality of air inlets 111 include a first air inlet 113 and a second air inlet 115, the first air inlet 113 and the second air inlet 115 being located on both sides of the air outlet 121 respectively; wherein, the first air inlet 113 is adapted to correspond to the first ventilation component, the second air inlet 115 is adapted to correspond to the second ventilation component, and the air outlet 121 is adapted to correspond to the cooking device.

[0063] In this embodiment, the first air inlet 113 and the second air inlet 115 correspond to different ventilation components, which can better meet the ventilation needs of different areas in the kitchen and further improve the ventilation effect and heat exchange efficiency of the air conditioner. Meanwhile, the corresponding arrangement of the air outlet 121 with the cooking device can more effectively remove heat, fumes, and odors generated during cooking from the kitchen, providing users with a more comfortable and healthy cooking environment. Optionally, the first ventilation frame is a door, and the second ventilation component is a window. Optionally, the cooking device is a stove or a range hood, etc.

[0064] Optionally, such as Figure 2As shown, the panel 10 includes an air inlet frame 11 and an air outlet frame 12. The air inlet frame 11 has an air inlet 111; the air outlet frame 12 has an air outlet 121. The air outlet frame 12 and the air inlet frame 11 are arranged along the length of the panel 10. The air inlet frame 11 and the air outlet frame 12 are integral structures, or the air inlet frame 11 and the air outlet frame 12 are detachably connected.

[0065] In this embodiment, the arrangement of the air inlet frame 11 and the air outlet frame 12 facilitates the spacing between the air inlet 111 and the air outlet 121, ensuring smooth airflow. When the air inlet frame 11 and the air outlet frame 12 are an integral structure, the overall structural strength and stability of the panel assembly are improved, air leakage at component connections is reduced, and airflow efficiency is increased. When the air inlet frame 11 and the air outlet frame 12 are detachably connected, it facilitates cleaning and maintenance of the panel assembly, reduces usage costs, and extends the product's lifespan. Furthermore, the detachable connection method allows for flexible adjustments based on different kitchen spaces and usage needs, improving the applicability and versatility of the panel assembly.

[0066] For example, the air inlet frame 11 and the air outlet frame 12 are detachably connected by means of clips, screws or magnets.

[0067] Optionally, the ratio of the length of the air inlet frame 11 to the width of the air inlet frame 11 is greater than or equal to 3 and less than or equal to 5; and / or, the ratio of the length of the air outlet frame 12 to the width of the air outlet frame 12 is greater than or equal to 3 and less than or equal to 5.

[0068] In this embodiment, by limiting the ratio of the length to the width of the air inlet frame 11 and the air outlet frame 12, the frame structure can be made more reasonable, further improving airflow efficiency. When the ratio is between 3 and 5, sufficient air inlet and outlet areas can be ensured to meet the ventilation requirements of the air conditioner, while also making the frame structure more compact, saving space, and adapting to different kitchen installation environments. While ensuring the performance of the air conditioner, the aesthetic appearance and space utilization of the air conditioner are also improved.

[0069] When the aspect ratio of the air inlet frame 11 and the aspect ratio of the air outlet frame 12 are greater than or equal to 3, the panel 10 can achieve an extremely narrow visual effect, avoiding the bulkiness caused by an excessively wide frame. This also reduces installation space and enhances the product's aesthetics and spatial adaptability.

[0070] When the aspect ratio of the air inlet frame 11 and the aspect ratio of the air outlet frame 12 are less than or equal to 5, the air inlet frame 11 and the air outlet frame 12 have sufficient width to install other components, thus realizing the basic functions and structural stability of the panel 10.

[0071] The embodiments disclosed herein limit the aspect ratio of the air inlet frame 11 and / or the air outlet frame 12 to a range of 3 to 5. This allows the panel 10 to achieve an extremely narrow visual effect while still fulfilling the basic functions of the air inlet frame 11 and the air outlet frame 12, enabling other components to be properly installed on the air inlet frame 11 or the air outlet frame 12. This balances the aesthetics and functionality of the panel 10.

[0072] It is understandable that the aspect ratio of the air intake frame 11 and the aspect ratio of the air outlet frame 12 can be 3, 3.5, 4, 4.5, or 5.

[0073] Optionally, the aspect ratio of the air inlet frame 11 and the aspect ratio of the air outlet frame 12 are 4.

[0074] This design ensures that the panel 10 has a uniform, linear distribution, achieving an extremely narrow visual effect while allowing for the proper installation of other components, thus balancing aesthetics and functionality. Furthermore, the unified aspect ratio of the air inlet frame 11 and the air outlet frame 12 optimizes the manufacturing cost of the panel 10 and improves production efficiency.

[0075] Optionally, the aspect ratio of the air inlet frame 11 is the same as that of the air outlet frame 12.

[0076] The air inlet frame 11 and the air outlet frame 12 are arranged adjacent to each other, and the length-to-width ratio of the air inlet frame 11 and the air outlet frame 12 are the same. This makes the overall appearance of the panel 10 body uniformly linearly distributed, presenting a narrow and long visual effect. This improves the aesthetics of the panel assembly. The same length-to-width ratio gives the air inlet frame 11 and the air outlet frame 12 better structural symmetry and coordination, and also enhances the structural stability of the panel assembly. In addition, during the manufacturing process, the same length-to-width ratio facilitates unified mold design and production, which can improve production efficiency and reduce production costs.

[0077] Optionally, such as Figure 1 As shown, the panel assembly also includes an air outlet guide plate 13, a light strip 16, and a display screen 161. The air outlet guide plate 13 is movably disposed at the air outlet 121 for opening or closing the air outlet 121. The light strip 16 is disposed at the air outlet 121 and is located on one side of the width direction of the air outlet guide plate 13. The display screen 161 is disposed at the air outlet 121 and is located on one side of the length direction of the air outlet guide plate 13.

[0078] In this embodiment, the air outlet guide plate 13 allows users to easily open or close the air outlet 121 as needed, enabling flexible control of the airflow and further improving the ease of use of the air conditioner. Simultaneously, the light strip 16 and display screen 161 installed at the air outlet 121 not only provide lighting for the kitchen but also display information such as the air conditioner's operating status and temperature, providing users with a more intuitive operating experience. This design integrates lighting, display, and ventilation functions, enhancing the product's functionality and practicality, and improving the user experience.

[0079] Optionally, the air conditioner also includes a plurality of louvers 15, which are movably disposed at the air outlet 121 for adjusting the air outlet 121 in the length direction of the panel 10.

[0080] In this embodiment, multiple oscillating blades 15 are provided to adjust the air outlet 121 along the length of the panel 10, allowing users to flexibly adjust the air outlet direction according to specific needs in the kitchen, further improving the flexibility and comfort of the air conditioner. Adjusting the oscillating blades 15 enables more precise temperature control and air distribution, preventing cold or hot air from blowing directly onto the user and improving user comfort. Simultaneously, the movable design of the oscillating blades 15 makes the panel assembly structure more flexible, adapting to different user habits and kitchen environments.

[0081] Optionally, there are multiple air inlet frames 11, including a first air inlet frame 112 and a second air inlet frame 114. The first air inlet frame 112 has a first air inlet 113, the second air inlet frame 114 has a second air inlet 115, and the air outlet frame 12 has an air outlet 121. The first air inlet frame 112 is located on one side of the air outlet frame 12 along the length direction of the panel 10, and the second air inlet frame 114 is located on the other side of the air outlet frame 12 along the length direction of the panel 10.

[0082] The first air inlet frame 112, the air outlet frame 12, and the second air inlet frame 114 are arranged sequentially along the length of the panel 10. The arrangement of multiple air inlet frames 11 increases the total return air area and improves the return air volume of the air conditioner, thereby enhancing the cooling or heating efficiency. The first air inlet frame 112 and the second air inlet frame 114 are located on both sides of the air outlet frame 12, and the first air inlet 113 and the second air inlet 115 are located on both sides of the air outlet 121. This symmetrical layout makes the return air more uniform and avoids the airflow imbalance caused by unilateral return air.

[0083] With the same aspect ratio of the air inlet frame 11 and the air outlet frame 12, the aspect ratios of the first air inlet frame 112, the air outlet frame 12, and the second air inlet frame 114 are also the same. By making the overall layout of the panel 10 compact and adjusting the overall aspect ratio of the control panel 10, the appearance of the panel 10 becomes more uniform and linearly distributed.

[0084] Optionally, the aspect ratio of the first air inlet frame 112, the air outlet frame 12, and the second air inlet frame 114 is all 4. This can more effectively enhance the visual effect of the extremely narrow panel 10, making the overall structure of the panel 10 more concise. At the same time, this also saves installation space and facilitates after-sales installation.

[0085] Optionally, such as Figures 17 to 20 As shown, the panel assembly also includes an air intake grille 40, which is located at the air intake 111; one end of the air intake grille 40 is snapped into the air intake frame 11, and the other end of the air intake grille 40 is magnetically connected to the air intake frame 11.

[0086] In this embodiment, one end of the air intake grille 40 is snapped into the air intake frame 11, and the other end of the air intake grille 40 is magnetically connected to the air intake frame 11. The magnetically connected end of the air intake grille 40 facilitates separation from the air intake frame 11, thereby facilitating operation of the other end of the air intake grille 40 snapped into the air intake frame 11, improving disassembly convenience, and eliminating the need for additional parts. This reduces maintenance costs and improves maintenance efficiency.

[0087] Optionally, one end and the other end of the air inlet grille 40 are arranged along the length direction of the air inlet 111. In this embodiment of the present disclosure, both ends of the air inlet grille 40 in the length direction are respectively connected to the air inlet frame 11, which can improve the connection stability and prevent the air inlet grille 40 from loosening and deforming when airflow passes through.

[0088] Optionally, such as Figure 18 , Figure 19 and Figure 20 As shown, the air intake frame 11 is provided with a magnetic component 116, and the other end of the air intake grille 40 is provided with a magnetic mating component 41. When the air intake frame 11 is connected to the air intake grille 40, the magnetic component 116 and the magnetic mating component 41 are magnetically attracted to each other. There are multiple magnetic components 116, which are arranged sequentially along the width direction of the air intake frame 11. The number of magnetic mating components 41 is the same as the number of magnetic components 116 and corresponds to each other.

[0089] In this embodiment, multiple magnetic components 116 and magnetic mating components 41 are provided at the other end of the air intake grille 40 and the air intake frame 11 along the length direction for magnetic attraction, which can improve the strength of magnetic attraction.

[0090] Optionally, the air intake grille 40 is configured with a first insertion hole, one end of the magnetic mating part 41 is inserted into the first insertion hole, and the other end of the magnetic mating part 41 is screwed to the air intake grille 40.

[0091] In this embodiment of the present disclosure, the air intake grille 40 is fixed with a magnetic coupling member 41 by a first insertion hole and screws, so that the magnetic coupling member 41 can be stably set on the air intake grille 40, and the magnetic coupling member will not fall off when the air intake grille 40 moves.

[0092] Optionally, such as Figure 19 and Figure 20 As shown, the air intake frame 11 is constructed with a second insertion hole 117. One end of the magnetic component 116 is inserted into the second insertion hole 117, and the other end of the magnetic component 116 is screwed to the air intake grille 40.

[0093] In this embodiment, the magnetic component 116 is also fixed to the air inlet frame 11 via the second insertion hole 117 and screws to prevent the magnetic component 116 from shifting and to ensure the accuracy of the fit between the magnetic component 116 and the magnetic mating component 41.

[0094] Optionally, such as Figure 17 and Figure 18 As shown, one end of the air inlet grille 40 is provided with a connecting hook 43. The connecting hook 43 includes a connecting arm 431 and a hook portion 432. One end of the connecting arm 431 is connected to the air inlet grille 40 and extends towards the air inlet 111 along the depth direction of the air inlet. The hook portion 432 is connected to the other end of the connecting arm 431 and extends along the length direction of the air inlet 111. The air inlet frame 11 is constructed with a connecting groove 118. When the air inlet grille 40 is connected to the air inlet frame 11, the hook portion 432 passes through the air inlet and engages with the connecting groove 118.

[0095] In this embodiment, one end of the air intake grille 40 is engaged with the air intake frame 11 via a connecting hook 43 and a connecting groove 118. Thus, when disassembling the air intake grille 40, the hook 432 is removed from the connecting groove 118, thereby separating one end of the air intake grille 40 from the air intake frame 11. Then, force is applied directly to the other end to separate the magnetic component 116 and the magnetic mating component 41.

[0096] Optionally, there are multiple connecting hooks 43, which are spaced apart along the width direction of one end of the air inlet grille 40. The number of connecting grooves 118 is the same as the number of connecting hooks 43 and they correspond one-to-one.

[0097] In this embodiment, one end of the air intake grille 40 is connected to the air intake frame 11 by multiple connecting hooks 43, which further improves the connection stability between the air intake grille 40 and the air intake frame 11.

[0098] Optionally, one end of the air intake grille is provided with a first groove. When the air intake frame is connected to the air intake grille, one end of the air intake frame is located in the first groove. The first groove includes a first groove wall and a second groove wall that are arranged opposite to each other along the depth direction of the air intake. The first groove wall includes grille bars, and the second groove wall is provided with a connecting hook; and / or,

[0099] The other end of the air intake frame is provided with a second groove. When the air intake frame is connected to the air intake grille, the other end of the air intake grille is located in the second groove. The wall of the second groove facing the air intake grille is provided with a magnetic component, and the wall of the air intake grille facing the second groove is provided with a magnetic mating component.

[0100] Optionally, such as Figure 22 As shown, the panel assembly also includes a connecting rib 44 and a filter device 441. The connecting rib 44 is disposed on the air inlet frame 11. The filter device 441 is disposed on the air inlet 111 and is located between the connecting rib 44 and the air inlet grille 40.

[0101] In this embodiment of the present disclosure, the connecting rib 44 fixes the filter device 441 between the air inlet grille 40 and the air inlet 111, and the filter device 441 can filter the air flowing in through the air inlet 111.

[0102] Optionally, such as Figure 17 , Figure 18 and Figure 21 As shown, the air intake grille 40 is provided at the air intake 111. The air intake grille 40 includes grille bars 45, which extend along the length direction of the air intake 111. The grille bars 45 are partially inclined upward along the airflow direction of the air intake 111.

[0103] In this embodiment, the grille strip 45 is partially inclined upwards, which effectively prevents foreign objects from entering the air conditioner. Furthermore, the inclined grille strip 45 guides airflow more smoothly through the air inlet 111, reducing airflow resistance and improving the efficiency and stability of return air.

[0104] Optionally, there may be multiple grille strips 45, which are arranged at intervals along the width of the air inlet 111. In this way, the multiple grille strips 45 can more comprehensively organize and guide the airflow in the air inlet 111.

[0105] Optionally, when the air outlet guide plate is open, it can tilt upwards along the air outlet direction, and the grille bars of the air inlet grille can also tilt upwards along the air inlet direction. This allows the outlet and return airflows to flow on opposite sides of the panel, thus making their airflow paths independent and reducing interference between them. This effectively avoids turbulent flow of hot and cold air caused by adjacent air inlets and outlets, reducing the risk of condensation.

[0106] Optionally, such as Figure 17 As shown, the grille bar 45 includes a connecting section 451 and a guide section 454. The connecting section 451 connects to both sides of the guide section 454 and is connected to the air inlet frame 11. A portion of the connecting section 451 is parallel to the plane of the air inlet 111, and the guide section 454 is inclined relative to the air inlet 111. Optionally, as... Figure 21 As shown, the arrow indicates the direction of airflow at the air inlet. Along the direction of airflow at the air inlet 111, the air guide section 454 is inclined upward.

[0107] In this embodiment, the air guide section 454 is inclined, which allows it to guide the airflow of the air inlet 111, reducing airflow resistance and effectively preventing dust or debris from entering the system, thus protecting the interior of the air conditioner. Additionally, the connecting section 451 is used to connect to the air inlet frame 11. The connecting section 451 is parallel to the plane of the air inlet 111, allowing it to connect to the air inlet frame 11 in the width direction of the air inlet 111 without increasing the depth required for fixing the grille strip 45. This allows for a reduction in the thickness of the air inlet frame 11. Alternatively, the connecting section 451 can be attached to the outer or inner wall of the air inlet frame 11, further increasing the connection area and thus improving the connection strength.

[0108] Optionally, the connecting section 451 includes a planar section 452 and a transition section 453. The planar section 452 fits against the outer wall of the air inlet frame 11 and is connected to the air inlet frame 11. The transition section 453 is connected between the planar section 452 and the air guide section 454. In this case, at least a portion of the transition section 453 is inclined toward the flow direction of the airflow at the air inlet 111 along the direction from the planar section 452 to the air guide section 454.

[0109] In this embodiment, the planar segment 452 is parallel to the plane of the air inlet 111, allowing the planar segment 452 to fit snugly against the air outlet frame 12. This increases the connection area and strength between the grille strip 45 and the air inlet frame 11. The transition segment 453 allows for a smooth connection between the planar segment 452 and the guide segment 454, preventing abrupt changes in the grille strip 45 that could affect airflow. Furthermore, the inclined design of the transition segment 453 also guides the airflow, further directing the airflow direction and allowing air to enter the air conditioner more efficiently, reducing eddies and energy loss.

[0110] Optionally, one end of the air intake grille is provided with a first groove, the two ends of the first groove being a flat section and a connecting hook, the flat section fitting against the outer wall surface of one end of the air intake frame, and the connecting hook engaging with the inner wall surface of one end of the air intake frame.

[0111] Optionally, the other end of the air intake frame is provided with a second groove. When the air intake frame is connected to the air intake grille, the other end of the air intake grille is located in the second groove. The wall surface of the second groove facing the air intake grille is provided with a magnetic element 116, and the wall surface of the air intake grille facing the second groove is provided with a magnetic mating element.

[0112] Optionally, the ratio of the length of the connecting section 451 to the length of the air guide section 454 is in the range of 1:10 to 1:6.

[0113] In this embodiment, when the ratio of the length of the connecting section 451 to the length of the guide section 454 is less than 1:10, the length of the connecting section 451 is too short, which is not conducive to the connection with the air inlet frame 11, nor is it convenient for the smooth transition of the transition section 453. When the ratio of the length of the connecting section 451 to the length of the guide section 454 is greater than 1:6, the length of the connecting section 451 is too large and the length of the guide section 454 is too short, which increases the resistance to airflow. Therefore, by setting the ratio of the length of the connecting section 451 to the length of the guide section 454 to be within the range of 1:10 to 1:6, the connection strength of the grille bar 45 can be guaranteed, the resistance can be reduced, and the smoothness of airflow can be guaranteed.

[0114] Optionally, the connecting section 451 and the air guide section 454 have the same width. This facilitates the processing of the grille strip 45.

[0115] Optionally, such as Figure 21 As shown, the angle α between the plane containing the air guide section 454 and the air inlet 111 is greater than or equal to 30° and less than or equal to 60°.

[0116] In this embodiment, when the angle α between the air guide section 454 and the plane containing the air inlet 111 is greater than or equal to 30°, the air inlet 111 can open a sufficient return air area, thereby effectively guiding the return airflow into the air inlet 111. This avoids problems such as poor return airflow caused by an insufficient opening area of ​​the air inlet 111.

[0117] When the angle α between the plane containing the air guide section 454 and the air inlet 111 is less than or equal to 60°, it can effectively guide the return airflow into the air inlet 111, reduce turbulence caused by airflow interference, thereby avoiding condensation caused by airflow mixing and improving return air efficiency.

[0118] This embodiment of the invention limits the angle α between the air guide section 454 and the plane containing the air inlet 111 to 30°–60°, thereby reducing turbulence caused by airflow interference and preventing condensation due to airflow mixing, while also improving return air efficiency. It is understood that the grille bar 45 can also be configured as an adjustable structure, capable of rotating relative to the air inlet frame 11 to adjust the opening angle of the air inlet 111.

[0119] It is understandable that the angle α between the plane containing the air guide section 454 and the air inlet 111 can be 30°, 35°, 40°, 45°, 50°, 55°, or 60°.

[0120] Optionally, the angle α between the plane containing the air guide section 454 and the air inlet 111 is 45°. This optimizes return air efficiency and reduces airflow interference. The 45° tilt angle not only allows the air inlet 111 to open a sufficient area to avoid obstructed return airflow, but also effectively guides the return airflow into the air inlet 111. This reduces turbulence caused by airflow mixing, prevents condensation, and improves return air efficiency.

[0121] Optionally, the ratio of the width of a grille strip 45 in the width direction of the air inlet 111 to the width of the air inlet 111 is greater than or equal to 0.1 and less than or equal to 0.2.

[0122] In this embodiment, if the width of a single grille bar 45 is too small, its strength is low, and its airflow guidance path is short, resulting in an insignificant airflow guiding effect. If the width of a single grille bar 45 is too large, the large width will cause significant resistance when the tilt angle is limited. The ratio of the width of a single grille bar 45 in the width direction of the air inlet 111 to the width of the air inlet 111 is between 0.1 and 0.2. This ensures both the strength and airflow guiding effect of the grille bar 45 without increasing resistance, thus guaranteeing airflow.

[0123] For example, the ratio of the width of a grille strip 45 in the width direction of the air inlet 111 to the width of the air inlet 111 is 0.1, 0.13, 0.14, 0.15, 0.16, 0.18, 0.19 or 0.2.

[0124] Optionally, the air intake grille 40 also includes a grille plate 46, located at the top and bottom of the air intake grille 40. The grille plate 46 is connected to the air intake frame 11, and one end of the grille strip 45 is connected to the outer end of the grille plate 46. The length of the grille plate 46 along the depth direction of the air intake 111 is greater than or equal to the length of the grille strip 45 along the depth direction of the air intake 111. The grille plate 46 provides connection space for the connection between the upper and lower ends of the air intake grille 40 and the air intake frame 11, ensuring connection strength and stability.

[0125] Optionally, the ratio of the length of the grille plate 46 along the depth direction of the air inlet 111 to the length of the grille strip 45 along the depth direction of the air inlet 111 is greater than or equal to 1.5 and less than or equal to 3.5.

[0126] In this embodiment, the depth of the grille plate 46 is greater than the depth of the grille strip 45. This avoids the grille strip 45 occupying a large depth of the air inlet 111, thus preventing increased airflow resistance. The ratio of the length of the grille plate 46 along the depth direction of the air inlet 111 to the length of the grille strip 45 along the depth direction of the air inlet 111 is set between 1.5 and 3.5. This ensures the strength of the grille strip 45 and keeps the airflow resistance within a reasonable range, ensuring smooth airflow.

[0127] For example, the ratio of the length of the grille plate 46 along the depth direction of the air inlet 111 to the length of the grille strip 45 along the depth direction of the air inlet 111 is 1.5, 1.8, 2, 2.5, 2.8, 3, etc.

[0128] Optionally, the air intake grille 40 also includes a sealing strip 47, which is adapted to be disposed on the side of the air intake frame 11 facing the mounting base for sealing the air intake frame 11 and the mounting base.

[0129] In this embodiment, the sealing strip 47 can seal the connection between the air inlet frame 11 and the mounting base to prevent air leakage. Here, the mounting base is a ceiling, suspended ceiling, etc.

[0130] Optionally, such as Figure 18 As shown, the air intake grille 40 also includes a connecting rib 48, which extends along the width direction of the air intake 111 and connects between multiple grille bars 45.

[0131] In this embodiment of the disclosure, the connecting rib 48 can connect multiple grille strips 45. In this way, in addition to connecting the two ends of the grille strip 45 to the two ends of the air inlet 111, the grille strip 45 can also be connected to the middle part of the grille strip 45, which improves the strength and stability of the grille strip 45 and prevents the grille strip 45 from bending and deforming due to its excessive length.

[0132] Optionally, such as Figures 14 to 16 As shown, the panel assembly also includes an air outlet guide plate 13, an air outlet frame 12 with an air outlet 121, and a first magnetic element 122. The air outlet guide plate 13 is movably disposed at the air outlet 121 of the air conditioner and is used to open or close the air outlet 121. The air outlet guide plate 13 is provided with a second magnetic element 131 adapted to the first magnetic element 122. When the second magnetic element 131 is magnetically connected to the first magnetic element 122, the air outlet guide plate 13 closes the air outlet 121. At least one of the first magnetic element 122 and the second magnetic element 131 is an electromagnetic induction device. The electromagnetic reaction device is configured to charge and magnetize when the air conditioner is powered off, and drive the second magnetic element 131 to magnetically connect with the first magnetic element 122, so that the air outlet guide plate 13 closes the air outlet 121.

[0133] In this embodiment, when the air conditioner is powered off or the limiting closing structure of the air outlet guide plate 13 fails, the electromagnetic induction device can automatically charge and become magnetized. The electromagnetic induction device drives the second magnetic component 131 to magnetically connect with the first magnetic component 122, thereby closing the air outlet 121. In this way, the air outlet guide plate 13 can automatically close the air outlet 121 when the air conditioner is powered off. This prevents the air outlet 121 from remaining open, preventing external dust or foreign objects from entering the outlet. Especially when the air conditioner is located in the kitchen, it prevents oil fumes from entering the air outlet 121, reducing performance degradation and equipment failure risks caused by dust accumulation, and extending the service life of the air conditioner. Furthermore, in this embodiment, the air outlet assembly achieves the opening and closing of the air outlet guide plate 13 through magnetic connection, eliminating the need for complex mechanical structures or additional driving devices. This simplifies the overall structure, reduces costs, and improves the stability and service life of the air conditioner.

[0134] Optionally, the second magnetic component 131 is detachably connected to the air outlet guide plate 13 to facilitate replacement and maintenance of the second magnetic component 131.

[0135] Optionally, the wall surface of the air outlet guide plate 13 facing the air outlet 121 is constructed with a first mounting plate 132 and a second mounting plate 133. The first mounting plate 132 and the second mounting plate 133 are spaced apart and a mounting groove 134 is defined between the first mounting plate 132 and the air outlet guide plate 13. A first gap is formed between the first mounting plate 132 and the air outlet guide plate 13, and a second gap is formed between the second mounting plate 133 and the air outlet guide plate 13. The second magnetic component 131 includes a magnetic component body and connecting ends connected to both ends of the magnetic component body. When the second magnetic component 131 is connected to the air outlet guide plate 13, the two connecting ends are respectively inserted into the first gap and the second gap, and the magnetic component body is located in the mounting groove 134 so that the magnetic component body and the second magnetic component 131 cooperate.

[0136] In this embodiment, the magnetic component body of the second magnetic component 131 can be stably installed in the groove, improving the installation stability of the magnetic component 116 and reducing the risk of the magnetic component 116 loosening or falling off due to vibration or external force. Furthermore, the first mounting plate 132 and the second mounting plate 133 define a mounting groove 134, which is equipped with the magnetic component body. This allows the magnetic component body to accurately engage with the first magnetic component 122 of the air outlet frame 12, ensuring the automatic closing of the air outlet guide plate 13.

[0137] Optionally, the air outlet guide plate 13 is movably disposed at the air outlet 121. The air outlet guide plate 13 includes a first side and a second side disposed opposite to each other along the width direction of the air outlet guide plate 13. When the air outlet guide plate 13 is open, the first side is located outside the air outlet, wherein the second magnetic element 131 is disposed close to the first side. In this way, when the first magnetic element 122 and the second magnetic element 131 generate magnetic force, the first magnetic element 122 can magnetically attract and drive the first side of the air outlet guide plate 13 to move toward the air outlet 121, thereby closing the air outlet 121.

[0138] Optionally, the air outlet frame 12 includes an air outlet frame body and a reinforcing plate 123. The air outlet frame body has an air outlet 121. The reinforcing plate 123 is located in the middle of the length direction of the air outlet 121 and is movably connected to the air outlet guide plate 13. In the length direction of the air outlet 121, the distance between the second magnetic element 131 and the reinforcing plate 123 is less than the distance between the second magnetic element 131 and the two ends of the length direction of the air outlet 121.

[0139] In this embodiment, the reinforcing plate 123 is disposed in the middle of the air outlet 121, which can improve the strength of the air outlet frame 12. The reinforcing plate 123 is movably connected to the air outlet guide plate 13, so that the reinforcing plate 123 can provide a connection position for the air outlet guide plate 13, so that the air outlet guide plate 13 can be movably disposed in the air outlet 121. The second magnetic element 131 is disposed close to the reinforcing plate 123, so that the first magnetic element 122 is also close to the middle of the length direction of the air outlet guide plate 13. Thus, the first magnetic element 122 and the second magnetic element 131 apply force to the middle of the air outlet guide plate 13, so that the air outlet guide plate 13 can move as a whole toward the air outlet 121, avoiding deformation of the air outlet guide plate 13 or incomplete sealing.

[0140] Optionally, the air outlet frame 12 includes an air outlet frame body and a swivel assembly. The air outlet frame body has an air outlet 121. The swivel assembly includes a swivel connecting rod 151 and a plurality of swivel blades 15. The plurality of swivel blades 15 are arranged sequentially and spaced apart along the length direction of the swivel connecting rod 151. The first magnetic element 122 is disposed on the upper wall surface of the air outlet 121 and is spaced apart and sleeved on the outside of the swivel connecting rod 151.

[0141] In this embodiment, the oscillating blade connecting rod 151 and the oscillating blade 15 enable the oscillating blade 15 to rotate along the length of the air outlet 121 to adjust the air outlet 121's airflow direction along its length. A first magnetic element 122 is movably sleeved on the outside of the oscillating blade connecting rod 151. The first magnetic element 122 is fixed by connecting to the upper wall of the air outlet 121. Simultaneously, the first magnetic element 122 extends downwards and can be spaced outwards from the oscillating blade connecting rod 151, thus ensuring the size and magnetic force of the first magnetic element 122 while preventing interference between the first magnetic element 122 and the oscillating blade connecting rod 151.

[0142] Optionally, the air outlet guide plate 13 is rotatably and detachably connected to the air outlet frame 12.

[0143] In this embodiment, the air outlet guide plate 13 is rotatably connected to the air outlet frame 12, so that the air outlet guide plate 13 can open or close the air outlet 121. At the same time, the air outlet guide plate 13 can also be removed from the air outlet frame 12 to facilitate the inspection, maintenance and replacement of components such as the air outlet guide plate 13, the second magnetic component 131, and the oscillating blade 15 and the second magnetic component 131 in the air outlet 121, thereby improving maintenance convenience and reducing maintenance costs.

[0144] Optionally, such as Figures 4 to 6 As shown, the air outlet frame 12 has a first rotating hole 124. The panel assembly also includes a rotating mating plate 143 and a rotating shaft 142. The rotating mating plate 143 protrudes from the wall surface of the air outlet guide plate 13 facing the air outlet 121. The rotating mating plate 143 has a second rotating hole 141, which corresponds to the first rotating hole 124. The rotating shaft 142 is movably connected to the rotating mating plate 143. When the rotating shaft 142 moves to the first position, it passes through the second rotating hole 141 and the first rotating hole 124, so that the air outlet guide plate 13 is rotatably connected to the air outlet frame 12. When the rotating shaft 142 moves to the second position, it disengages from the first rotating hole 124, so that the air outlet guide plate 13 is separated from the air outlet frame 12.

[0145] In this embodiment, when the rotating shaft 142 passes through both the first rotating hole 124 and the second rotating hole 141, the rotating shaft 142 can connect the air outlet guide plate 13 and the air outlet frame 12, and also enable a rotatable connection between the air outlet guide plate 13 and the air outlet frame 12. When the rotating shaft 142 disengages from the first rotating hole 124, the rotating shaft 142 is only connected to the air outlet guide plate 13, thus achieving the disassembly of the air outlet guide plate 13 from the air outlet frame 12. Through the arrangement of the rotating shaft 142, the first rotating hole 124, and the second rotating hole 141, the rotatable and detachable connection between the air outlet guide plate 13 and the air outlet frame 12 can be achieved with a single set of components, reducing the number of components and lowering costs.

[0146] Optionally, the rotating mating plate 143 is configured with a sliding portion 144, allowing the rotating shaft 142 to slide along the sliding portion 144 at a first position and a second position. This makes the movement of the rotating shaft 142 smoother and avoids jamming or misalignment.

[0147] Optionally, the rotating mating plate 143 is also provided with a limiting part 145, and the rotating shaft 142 is provided with a limiting mating part 146. When the rotating shaft 142 moves to the first position, the limiting part 145 and the limiting mating part 146 cooperate to restrict the rotating shaft 142 from moving away from the second position.

[0148] In this embodiment of the present disclosure, when the rotating shaft 142 moves to the first position, the air outlet guide plate 13 is connected to the air outlet frame 12. The limiting part 145 and the limiting mating part 146 can restrict the rotating shaft 142 from moving toward the second position, thereby preventing the air outlet guide plate 13 and the air outlet frame 12 from separating and ensuring the stability of the connection.

[0149] Optionally, the limiting part 145 includes a limiting protrusion 214, and the limiting mating part 146 includes a protrusion. The protrusion is provided on both sides of the rotation shaft 142 in the width direction. The limiting protrusions 214 are located on both sides of the rotation shaft 142 in the width direction, and the two limiting protrusions 214 define a sliding groove. The rotation shaft 142 slides within the sliding groove. When the limiting part 145 and the limiting mating part 146 are engaged, the protrusion is located on the side of the limiting protrusion 214 facing the first rotation hole 124, and the protrusion abuts against the limiting protrusion 214 to prevent the rotation shaft 142 from moving to the second position. The sliding part 144 includes a sliding groove.

[0150] Optionally, the protrusion is made of an elastic material. When an external force is applied, the protrusion can deform to pass through the sliding groove and then contact the limit, so that the rotating shaft 142 moves toward the second position.

[0151] Optionally, such as Figures 3 to 11 As shown, the air conditioner also includes a transfer duct 20. This embodiment of the present disclosure provides a transfer duct for an air conditioner. The transfer duct 20 includes a transfer part 21 and a bend part 22. The air inlet 205 of the transfer part is connected to the air duct of the air conditioner. The bend part 22 is bent. The air inlet 24 of the bend part is connected to the air outlet of the transfer part 21, and the air outlet 25 of the bend part is connected to the air outlet 121 of the air conditioner.

[0152] In this embodiment, the transition duct 20 connects the air duct of the air conditioner and the air outlet 121, allowing the temperature-regulating gas inside the air conditioner to flow into the room through the air outlet 121. The bend 22 is bent, so that the airflow in the duct flows into the bend 22 after passing through the transition 21, then turns within the bend 22, and finally flows out from the air outlet 121 of the air conditioner. This allows for adjustment of the air outlet direction of the air conditioner, making the air outlet position and direction more flexible. It achieves a flexible connection between the air conditioner's duct and the air outlet 121, overcoming the limitations of traditional direct airflow. Furthermore, when the air conditioner is embedded in the ceiling, the transition duct can be designed in conjunction with the height limitations of the installation space, with the bend angle of the bend 22 and the elevation angle of the air outlet 121 linked, enabling switching between ceiling-mounted and oblique airflow modes, and increasing the airflow distance.

[0153] Optionally, the ratio of the air outlet area of ​​the transition section 21 to the air outlet area of ​​the bend section 25 is greater than or equal to 0.9 and less than or equal to 1.1.

[0154] In this embodiment, when the ratio of the area of ​​the air outlet of the transition section 21 to the area of ​​the air outlet 25 of the bend is less than 0.9, the air outlet area of ​​the transition section 21 is small, which increases the resistance of the airflow from the transition section 21 to the bend 22, resulting in significant airflow loss. When the ratio of the area of ​​the air outlet of the transition section 21 to the area of ​​the air outlet 25 of the bend is greater than 1.1, the air outlet area of ​​the bend 22 becomes smaller, increasing the resistance of airflow and also increasing noise. By limiting the area ratio of the air outlet of the transition section 21 to the area of ​​the air outlet 25 of the bend to the range of 0.9 to 1.1, a quasi-uniform cross-section transition of the airflow channel is achieved, ensuring smooth airflow turning while taking into account noise reduction, airflow, and adaptability to different installation scenarios.

[0155] Optionally, the ratio of the air outlet area of ​​the transition section 21 to the air outlet area of ​​the bend section 25 is 1.

[0156] In this embodiment, the air outlet of the transition section 21 and the air outlet 25 of the bend have the same area. This maximizes the airflow achievement rate, reduces airflow loss, and lowers noise. Furthermore, the identical area enables stepless speed transition of the airflow channel, completely eliminating turbulent noise caused by abrupt changes in cross-sectional area. Compared to the range of 0.9 to 1.1, the identical area of ​​the air outlet of the transition section 21 and the air outlet 25 of the bend is suitable for high static pressure environments, improving airflow delivery efficiency.

[0157] Optionally, the ratio of the area of ​​the air inlet 205 of the transition section to the area of ​​the air outlet of the transition section 21 is greater than or equal to 1.2 and less than or equal to 1.5.

[0158] In this embodiment, when the ratio of the area of ​​the air inlet 205 of the transition section to the air outlet area of ​​the transition section 21 is less than 1.2, the change in airflow area within the transition section 21 is small, resulting in a slower airflow velocity within the transition section 21. This, in turn, leads to a slower airflow velocity into the bend section 22, affecting the air volume output of the air conditioner. When the ratio of the area of ​​the air inlet 205 of the transition section to the air outlet area of ​​the transition section 21 is greater than 1.5, the change in airflow area within the transition section 21 is faster, leading to increased airflow pressure and resistance, affecting the air volume output and noise. A narrowing ratio of 1.2-1.5 ensures increased airflow velocity while controlling pressure loss within a reasonable range.

[0159] Optionally, the ratio of the area of ​​the air inlet 205 of the transition section to the area of ​​the air outlet of the transition section 21 is 1.3.

[0160] In this embodiment of the present disclosure, the ratio of the area of ​​the air inlet 205 of the adapter to the area of ​​the air outlet of the adapter 21 is set to 1.3, which can ensure that the airflow resistance is small and the flow rate is guaranteed, while reducing noise and ensuring the air volume.

[0161] Optionally, such as Figures 4 to 6 As shown, there are multiple bends 22, including a first bend 225 and a second bend 226. The air outlet of the transition section 21 includes a first outlet 218 and a second outlet 219. The first outlet 218 corresponds to and is connected to the air inlet 111 of the first bend 225, and the second outlet 219 is connected to the air inlet 111 of the second bend 226. The first bend 225 and the second bend 226 are arranged alternately, so the first outlet 218 and the second outlet 219 are arranged alternately. The air outlet 121 of the first bend 225 and the air outlet 121 of the second bend 226 are both connected to the air outlet 121 of the air conditioner. In this way, when the area of ​​the air outlet 121 is large, the air is guided by multiple bends 22 to ensure the uniformity of the air outlet 121.

[0162] Here, the ratio of the air outlet area of ​​the transition section 21 to the air outlet area of ​​the bend section 25 refers to the ratio of the total area of ​​the air outlets of the transition section 21 to the total area of ​​the air outlets of the bend section 25. For example, when the air outlets of the transition section 21 only include the first outlet 218 and the second outlet 219, the ratio of the air outlet area of ​​the transition section 21 to the air outlet area of ​​the bend section 25 refers to the ratio of the sum of the areas of the first outlet 218 and the second outlet 219 to the sum of the areas of the air outlet 121 of the first bend section 225 and the air outlet 121 of the second bend section 226.

[0163] Optionally, the air inlet 205 of the transition section is one, and the air inlet 205 of the transition section is connected to the first outlet 218 and the second outlet 219. In this way, the outlet of the air duct is connected to the air inlet 205 of the transition section, so that most or all of the airflow in the air duct can flow into the transition section 21 through the air inlet 205 of the transition section, and then flow from the transition section 21 through the first outlet 218 and the second outlet 219 to the first bend 225 and the second bend 226 respectively, and then flow to the air outlet 121 and out from the air outlet 121.

[0164] Here, the ratio of the area of ​​the air inlet 205 of the transition section to the area of ​​the air outlet of the transition section 21 refers to the sum of the total area of ​​the air inlets 205 of the transition section and the total area of ​​the air outlets of the transition section 21. For example, when the air outlet of the transition section 21 includes only one air inlet 111, a first outlet 218, and a second outlet 219, the ratio of the area of ​​the air inlet 205 of the transition section to the area of ​​the air outlet of the transition section 21 refers to the ratio of the area of ​​the air inlet 205 of the transition section to the sum of the areas of the first outlet 218 and the second outlet 219.

[0165] During installation, the number of bends can be selected according to actual needs, or the air outlet direction of each bend can be adjusted as needed. This corresponds to setting the number of air outlets on the adapter 21. This design not only improves installation flexibility but also reduces installation difficulty.

[0166] Optionally, the adapter 21 includes a first air duct 2181 and a second air duct 2191. The first air duct 2181 connects the air inlet 205 and the first outlet 218 of the adapter. The second air duct 2191 connects the air inlet 205 and the second outlet 219 of the adapter. The first air duct 2181 and the second air duct 2191 are arranged side by side. The first outlet 218 and the second outlet 219 are located on the same side of the adapter 21 and are arranged opposite to the air inlet 205 of the adapter.

[0167] After entering the interior of the transition section 21 through the air inlet 205, the airflow flows into the first air duct 2181 and the second air duct 2191, and then exits through the first outlet 218 and the second outlet 219, respectively. The parallel arrangement of the first air duct 2181 and the second air duct 2191 allows the airflow to be evenly distributed in two directions, improving the uniformity and stability of the airflow. Placing the first outlet 218 and the second outlet 219 on the same side of the transition section 21 simplifies the installation process and improves its convenience and reliability. The opposite arrangement of the first outlet 218 and the second outlet 219 to the air inlet 205 of the transition section optimizes the airflow path, reduces resistance during transmission, and thus improves the transmission efficiency of the airflow.

[0168] It is understandable that the first air duct 2181 and the second air duct 2191 can also extend in different directions, so that the first outlet 218 and the second outlet 219 can vent air in different directions.

[0169] Optionally, such as Figure 4 As shown, the first air duct 2181 includes a first sidewall 201 near the second air duct 2191, and the second air duct 2191 includes a second sidewall 202 near the first air duct 2181. One end of the first sidewall 201 facing the air inlet 205 of the transition portion is connected to one end of the second sidewall 202 facing the air inlet 205 of the transition portion, and the connection is smoothly transitioned.

[0170] The first air duct 2181 and the second air duct 2191 are arranged side by side. The first sidewall 201 and the second sidewall 202 adjacent to the first air duct 2181 and the second air duct 2191 are connected, and the connection is smoothly transitioned, which makes the airflow towards the first air duct 2181 and the second air duct 2191 smoother. This can reduce the resistance of the airflow within the first air duct 2181 and the second air duct 2191, thereby reducing air volume loss and noise.

[0171] Optionally, the first air duct 2181 includes a third sidewall 203 away from the second air duct 2191, the third sidewall 203 being inclined inward along the air inlet 205 of the transition portion toward the first outlet 218, and the second air duct 2191 includes a fourth sidewall 204 away from the first air duct 2181, the fourth sidewall 204 being inclined inward along the air inlet 205 of the transition portion toward the second outlet 219.

[0172] The third sidewall 203 of the first air duct 2181 slopes inward along the air inlet 205 of the transition section towards the first outlet 218, and the fourth sidewall 204 of the second air duct 2191 slopes inward along the air inlet 205 of the transition section towards the second outlet 219, so that the two sides of the transition section 21 form a constricted structure along the flow direction of the airflow. The inwardly sloped third sidewall 203 can guide the airflow to flow more smoothly towards the first outlet 218, and the inwardly sloped fourth sidewall 204 can guide the airflow to flow more smoothly towards the second outlet 219. This allows the airflow to flow more concentratedly and smoothly within the first air duct 2181 and the second air duct 2191, reducing the resistance and eddies of the airflow when flowing within the transition section 21.

[0173] Optionally, such as Figure 4 and Figure 5 As shown, the adapter 21 includes an upper shell 211 and a lower shell 212 for the adapter air duct. The lower shell 212 is detachably connected to the upper shell 211 and encloses an adapter air cavity 213. The adapter air cavity 213 is adapted to connect between the air duct of the air conditioner and the air outlet 121 of the air conditioner. The adapter air cavity 213 includes a first air duct 2181 and a second air duct 2191.

[0174] In this embodiment of the present disclosure, the adapter 21 is provided by two detachable adapter duct upper shells 211 and adapter duct lower shells 212, which facilitates the installation and removal of the adapter 21 and makes it easier to maintain the adapter 21.

[0175] Optionally, such as Figure 5 As shown, the inner wall of the upper shell 211 of the transition air duct has one end structure with a buckle 215 and a protrusion 214, and the inner wall of the lower shell 212 of the transition air duct has the other end structure with a buckle 215 and a protrusion 214. When the upper shell 211 of the transition air duct and the lower shell 212 of the transition air duct are connected, the protrusion 214 is located inside the buckle 215.

[0176] In this embodiment, the connection between the snap-fit ​​215 and the snap-fit ​​protrusion 214 allows the connection between the upper shell 211 and the lower shell of the adapter duct to be completed without additional tools, simply by pushing or rotating, greatly improving installation efficiency. At the same time, this structure also facilitates disassembly, making it easy to clean and maintain the interior of the adapter duct 20.

[0177] Optionally, such as Figure 4 As shown, one of the end structures of the outer wall surface of the upper shell 211 of the transition air duct has a first connecting plate 216, and the other end structure of the outer wall surface of the upper shell 211 of the transition air duct has a second connecting plate 217. The first connecting plate 216 has a first screw hole, and the second connecting plate 217 has a second screw hole. Fasteners pass through the first screw hole and the second screw hole to connect the upper shell 211 of the transition air duct and the lower shell 212 of the transition air duct.

[0178] In this embodiment, the engagement of the screw hole and the fastener provides a high-strength connection, ensuring that the transition duct 20 will not loosen due to vibration or airflow impact during operation. Furthermore, the tightness of the screw hole connection helps improve the sealing performance of the transition duct 20 and reduces airflow leakage.

[0179] Optionally, such as Figure 4 As shown, the adapter 21 is sleeved on the outside of the bend 22, and the adapter 21 and the bend 22 are detachably connected; wherein, when the adapter 21 is connected to the bend 22, at least one first connecting plate 216 and at least one second connecting plate 217 correspond to the bend 22.

[0180] In this embodiment, the first connecting plate 216 and the second connecting plate 217 outside the adapter 21 correspond to the bend 22, and the adapter 21 is sleeved on the outside of the bend 22. This not only facilitates the disassembly and installation of the adapter 21 and the bend 22, but also strengthens the pre-tightening force of the adapter 21 on the bend 22 after the first connecting plate 216 and the second connecting plate 217 are connected by screws, thereby improving the connection stability of the adapter 21 and the bend 22.

[0181] Optionally, such as Figure 6 As shown, the cross-section of the air inlet 24 of the bend is elliptical, the cross-section of the air outlet of the transition part 21 matches the cross-section of the air inlet 24 of the bend, and the cross-section of the air inlet 205 of the transition part is square.

[0182] In this embodiment of the disclosure, the elliptical and square docking schemes can reduce the formation of vortices at the transition point compared to circular and square schemes, thereby reducing airflow noise. Here, elliptical refers to an ellipse or approximately elliptical shape.

[0183] Optionally, as shown in Figures 7 to 8 Figure 13 As shown, the adapter duct 20 is slidably connected to the panel assembly.

[0184] In this embodiment, the adapter duct 20 and the panel assembly are connected by a sliding connection, so that the adapter duct 20 or the panel assembly can be pulled out from one or two directions, which facilitates disassembly and installation without having to disassemble from multiple positions, thus improving the convenience of disassembly.

[0185] Optionally, the panel assembly includes a panel 10 and an air outlet 17. The panel 10 is configured with an air outlet 121. The air outlet 17 defines an air outlet cavity, which is connected between the air outlet 121 and the air outlet 121 of the transition air duct 20. The air outlet 17 is slidably connected to the transition air duct 20.

[0186] In this embodiment, the air outlet 17 is provided with an air outlet cavity, which connects the air outlet 121 and the transition duct 20, providing a transition for the airflow flowing from the transition duct 20 into the air outlet 121. Furthermore, the air outlet 17 is slidably connected to the transition duct 20, facilitating a sliding connection between the panel 10 and the transition duct 20. Optionally, the air outlet is connected to the side of the air outlet frame facing the transition duct.

[0187] Optionally, such as Figure 12 and Figure 13 As shown, a slider 171 is provided on the side of the air outlet 17 facing the connecting air duct 20, and sliders 171 are provided on both sides of the air outlet 121 in the width direction; a slide rail 221 is provided at the end of the connecting air duct 20 facing the air outlet 17, and the slider 171 is slidably disposed on the slide rail 221, and the length of the slider 171 matches the length of the slide rail 221.

[0188] In this embodiment, the length matching design of the slider 171 and the slide rail 221 ensures a high-precision sliding connection between the transition air duct 20 and the air outlet 17. This matching method can effectively reduce shaking and loosening during the sliding process and improve the stability of the overall structure.

[0189] Optionally, such as Figure 11 and Figure 13 As shown, the air outlet 25 of the bend is connected to the air outlet 17. The bend 22 includes a first end and a second end that are arranged opposite to each other along the length of the air outlet 121. The first end is provided with a first hook 222, which extends toward the air outlet 17. One end of the air outlet 17 is provided with a connection port 172. A second hook 173 is provided on the side of the connection port 172 away from the first hook 222. When the bend 22 is connected to the air outlet 17, the first hook 222 passes through the connection port 172 and engages with the second hook 173.

[0190] In this embodiment, the engagement of the first hook 222 and the second hook 173 enables quick connection and disassembly of the adapter duct 20 and the air outlet 17. While allowing the adapter duct 20 and the air outlet 17 to slide together, this improves the reliability of the mechanical connection, ensuring that the adapter duct 20 and the air outlet 17 will not loosen during use.

[0191] Optionally, such as Figures 11 to 13 As shown, the first end and / or the second end are provided with positioning grooves 223, and the wall surface of the air outlet 17 facing the connecting air duct 20 is provided with positioning protrusions 174. When the bend 22 is connected to the air outlet 17, the positioning protrusions 174 are inserted into the positioning grooves 223.

[0192] In this embodiment, the cooperation between the positioning groove 223 and the positioning protrusion 174 enables precise positioning of the bend 22 and the air outlet 17, ensuring alignment accuracy during connection. This effectively reduces deviations during installation.

[0193] Optionally, such as Figure 12 and Figure 13 As shown, the second end is constructed with a limiting guide post 224, which extends along the length of the air outlet 121. The other end of the air outlet 17 is constructed with a limiting guide groove 175. When the bend 22 is connected to the air outlet 17, the guide post is located in the limiting guide groove 175, and the limiting guide post 224 abuts against the groove wall of the limiting guide groove 175.

[0194] In this embodiment, the cooperation between the limiting guide post 224 and the limiting guide groove 175 provides precise guidance for the connection between the bend 22 and the air outlet 17, ensuring that the two can be quickly aligned and accurately connected during assembly. Simultaneously, the contact between the limiting guide post 224 and the groove wall effectively restricts the displacement of the bend 22 after installation, enhancing the stability of the connection.

[0195] Optionally, such as Figure 12 As shown, the air outlet 17 also includes a reinforcing plate 123, which is located in the middle of the length direction of the air outlet 17; wherein, the reinforcing plate 123 is connected to the second end of the bend 22. The setting of the reinforcing plate 123 effectively improves the overall structural strength of the air outlet 17, especially in the middle of the length direction, which can significantly reduce deformation caused by airflow impact or external force. The connection between the reinforcing plate 123 and the second end of the bend 22 further enhances the connection stability between the two, ensuring that they will not loosen due to vibration or airflow impact during operation.

[0196] Optionally, when the plurality of bends 22 include a first bend 225 and a second bend 226, the first bend 225 is located on one side of the reinforcing plate 123; the second bend 226 is located on the other side of the reinforcing plate 123, and the second end of the second bend 226 corresponds to the second end of the first bend 225; wherein, the reinforcing plate 123 is constructed with a limiting guide groove 175, the second end of the first bend 225 is constructed with a first limiting guide post 2241, and the second end of the second bend 226 is constructed with a second limiting guide post 2242, the first limiting guide post 2241 and the second limiting guide post 2242 are arranged side by side in the limiting guide groove 175, and the first limiting guide post 2241 and the second limiting guide post 2242 respectively abut against the two opposite groove walls of the limiting guide groove 175.

[0197] In this embodiment, the reinforcing plate 123 provides a connecting carrier for the second ends of the first bend 225 and the second bend 226, providing precise positioning and limiting functions for the first bend 225 and the second bend 226. Furthermore, two limiting guide posts 224 are disposed within a limiting guide groove 175, and the two limiting guide posts 224 can also abut against each other, thereby improving the connection stability between the two bends 22 and the reinforcing plate 123.

[0198] Optionally, such as Figure 8 As shown, the air conditioner also includes an insulation layer 23, which is fitted onto the outside of the air outlet 17. The insulation layer 23 has a mounting hole 231, and the air outlet 17 has a third hook 176. When the third hook 176 is located in the mounting hole 231, the insulation layer 23 is connected to the air outlet 17.

[0199] In this embodiment, the insulation layer 23 is connected to the air outlet 17 by a third hook 176, which improves the stability of the air outlet 17 and thus also improves the installation stability of the insulation layer 23.

[0200] Optionally, the insulation layer 23 includes a first insulation layer and a second insulation layer, with the first insulation layer fitted on the outside of the air outlet 17 and the second insulation layer fitted on the outside of the transition air duct.

[0201] Optionally, such as Figures 6 to 13 As shown, the transition duct 20 also includes a guide plate 30, which is located inside the bend 22; wherein, the guide plate 30 extends along the airflow direction inside the bend 22.

[0202] In this embodiment, the guide plate 30 is located inside the bend 22. Since the bend 22 is bent, the guide plate 30 extends along the airflow direction within the bend 22, effectively guiding the airflow at the bend, reducing airflow turbulence and energy loss caused by the bend, improving airflow transmission efficiency, and ensuring that hot and cold air can be delivered to the air outlet 121 more efficiently. Through the guiding effect of the guide plate 30, the airflow within the bend 22 is more stable, reducing noise and vibration caused by turbulence and airflow impact, reducing airflow resistance within the bend 22, preventing turbulence from forming inside the bend, avoiding airflow attenuation, reducing wind loss, lowering noise, and providing additional support for the internal structure of the bend 22, increasing the strength of the transition duct 20.

[0203] Optionally, the shape and size of the deflector 30 are matched with the shape and size of the bend 22, that is, the shape and size of the deflector are the same as or similar to the bend.

[0204] In this embodiment, the shape and size of the guide vane 30 are precisely matched to the bend 22, allowing it to fit the inner wall of the bend 22 to the maximum extent. This enables the guide vane 30 to efficiently guide the airflow along a predetermined path, reducing turbulence and eddies at the bend of the bend 22, thereby significantly reducing airflow resistance and optimizing airflow transmission efficiency.

[0205] Optionally, the deflector 30 extends in an arc shape along the direction from the air inlet 111 toward the air outlet 121.

[0206] In this way, the guide vane 30 can better guide the airflow along the arc path, making the airflow on the surface of the guide vane 30 smoother, reducing the resistance of the airflow, and thus reducing the noise generated during the airflow process.

[0207] The bend component has an L-shaped or similar structure, with the air inlet 111 and air outlet 121 located at the two ends of the L-shaped structure, allowing the bend component to effectively change the direction of the airflow. Correspondingly, the guide vane 30 is also L-shaped or similar, allowing it to better adapt to the structure of the bend component, thus enabling the airflow to flow more smoothly along the guide vane 30 during the turning process.

[0208] Optionally, as shown in Figure 7, one end of the guide plate 30 is located at the air inlet 24 of the bend, and the one end of the guide plate 30 divides the air inlet 24 of the bend into a first inlet 32 ​​and a second inlet 33, wherein the areas of the first inlet 32 ​​and the second inlet 33 are different.

[0209] In this embodiment, by dividing the air inlet 24 of the bend into a first inlet section 32 and a second inlet section 33 with different areas, the guide plate 30 can differentiate the airflow entering the bend section 22 according to airflow requirements. The larger inlet section can be used to meet high airflow requirements, while the smaller inlet section can be used for low airflow or air supply requirements in specific areas, thereby achieving more precise airflow control. In addition, the different areas of the two air inlets can divert airflow, redirect large airflow, and reduce wind loss.

[0210] Optionally, such as Figure 8 and Figure 10 As shown, the inside of the bend 22 defines a bend air cavity, and the guide plate 30 divides the bend air cavity into a first air cavity 34 and a second air cavity 35. The flow areas of the first air cavity 34 and the second air cavity 35 are different.

[0211] In this embodiment, by dividing the bend air cavity into a first air cavity 34 and a second air cavity 35 with different flow areas, the airflow can be differentiated according to the different needs of the air conditioner. The design of air cavities with different flow areas reduces airflow turbulence and energy loss within the bend 22, making the airflow smoother and more efficient as it passes through the bend 22. This design helps improve the overall air supply efficiency of the air conditioning system and ensures uniform airflow distribution in different areas. The divided air cavities effectively reduce the impact and turbulence of the airflow within the bend 22, thereby reducing noise and vibration caused by airflow turbulence.

[0212] Optionally, the distance between the guide vane 30 and the top wall of the bend 22 is a first distance, and the distance between the guide vane 30 and the bottom wall of the bend 22 is a second distance, wherein the ratio of the first distance to the second distance is greater than or equal to 1 / 3 and less than or equal to 3, or the ratio of the first distance to the second distance is greater than or equal to 1 / 2 and less than or equal to 2.

[0213] In this embodiment, when the ratio of the first distance to the second distance is less than 1 / 3 or greater than 3, the flow area of ​​one air cavity is too small, resulting in greater resistance, smaller airflow, and higher noise within the air cavity. Further limiting the ratio of the first distance to the second distance to between 1 / 2 and 2 ensures a smaller flow area for the air cavity, allowing for smooth airflow separation between the two air cavities, reducing wind loss, and lowering noise. By limiting the ratio of the first distance to the second distance within a reasonable range, the guide plate 30 can more effectively balance the airflow distribution within the bend 22. This avoids airflow deflection or localized turbulence caused by the guide plate 30 being too high or too low, ensuring more uniform airflow in both vertical and horizontal directions, thereby improving the efficiency and stability of airflow transmission.

[0214] For example, the ratio of the first distance to the second distance is 1 / 2. That is to say, the guide vane 30 is set at the top, and the area of ​​the air cavity above the guide vane 30 accounts for 1 / 3, while the area of ​​the air cavity below accounts for 2 / 3. This way, the air volume of the lower air cavity is large, which makes it easier for the air volume to bend and reduces wind loss.

[0215] Optionally, such as Figure 8 and Figure 11 As shown, the bend section includes an upper bend section housing 227 and a lower bend section housing 228, which together enclose the bend section air cavity. The guide plate 30 and the lower bend section housing 228 are an integral structure.

[0216] In this embodiment, the guide vane 30 and the lower housing 228 of the bend are integrated, eliminating the potential for loose connections or detachment in split structures and significantly enhancing the structural stability of the entire bend 22. The integrated design ensures a perfect match between the guide vane 30 and the internal space of the bend 22, enabling more precise airflow guidance. By optimizing the shape and position of the guide vane 30, the airflow distribution within the bend 22 is more uniform, reducing turbulence and resistance, thereby improving airflow transmission efficiency.

[0217] Optionally, the upper housing 227 and the lower housing 228 of the bend are detachably connected to facilitate inspection and cleaning of the interior of the bend. For example, the upper housing 227 and the lower housing 228 of the bend can be detachably connected using snap-fit ​​and / or screws.

[0218] Optionally, as shown in Figures 7 to 8 Figure 9 As shown, the guide plate 30 is constructed with guide ribs 31, which protrude from the wall of the guide plate 30 and extend along the airflow direction within the bend 22.

[0219] In this embodiment, the guide ribs 31 are disposed on the surface of the guide plate 30, which can divert the supply airflow, thereby avoiding or reducing airflow turbulence and improving the transmission efficiency of the supply airflow. The guide ribs 31 extend along the airflow direction within the bend 22, effectively guiding the exhaust airflow toward the outlet 25 of the bend. This makes the airflow on the surface of the guide plate 30 smoother, reducing the resistance and noise of the supply airflow on the surface of the guide plate 30.

[0220] Optionally, multiple guide ribs 31 are provided, spaced apart sequentially along the width of the guide plate 30. This allows for a more uniform distribution of airflow. Consequently, the airflow on the surface of the guide plate 30 becomes more orderly, improving the uniformity and stability of the outlet airflow.

[0221] Optionally, such as Figure 9As shown, the upper wall of the guide plate 30 is provided with a first guide rib 311, and the lower wall of the guide plate 30 is provided with a second guide rib 312. The first guide rib 311 and the second guide rib 312 are staggered along the width direction of the guide plate 30. This can improve the strength of the guide plate 30 and reduce the noise and vibration caused by airflow impact.

[0222] Optionally, when there are multiple guide vanes 30, the spacing between two adjacent guide ribs 31 gradually increases or remains unchanged along the airflow direction within the bend 22.

[0223] In this embodiment, the gradually increasing spacing between two adjacent guide ribs 31 can better adapt to changes in airflow velocity, reducing turbulence and vortex phenomena at bends, thereby improving the stability and efficiency of airflow transmission. The constant guide ribs 31 result in a more uniform airflow distribution and facilitate the processing of the guide ribs 31.

[0224] Optionally, the width L4 of a guide rib 31 along the width direction of the guide plate 30 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0225] In this embodiment, when the width L4 of the guide rib 31 is less than 1 mm, the width L4 is too small, resulting in weak airflow guidance. When the width L4 of the guide rib 31 is greater than 2 mm, the width is too large, leading to greater resistance and affecting the smoothness of airflow. When the width L4 of the guide rib 31 is between 1 mm and 2 mm, it can effectively guide airflow and reduce turbulence and eddies within the bend 22. This width design ensures that the airflow passes through the bend more smoothly under the guidance of the guide rib 31, thereby improving airflow transmission efficiency.

[0226] Optionally, the width L4 of a guide rib 31 along the width direction of the guide plate 30 is 1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm or 2mm.

[0227] For example, the distance L3 between two adjacent guide ribs 31 along the width direction of the guide plate 30 is greater than or equal to 25 mm and less than or equal to 35 mm.

[0228] In this embodiment, when the distance L3 between two adjacent guide ribs 31 along the width direction of the guide plate 30 is less than 25mm, the channel area between adjacent guide ribs 31 is small, increasing airflow resistance. When the distance between two adjacent guide ribs 31 along the width direction of the guide plate 30 is greater than 35mm, the flow area is too large, weakening the guiding effect of the guide ribs 31 on the airflow. By controlling the spacing between 25mm and 35mm, the airflow between the guide ribs 31 can be ensured to be more stable, thereby improving the efficiency of airflow transmission. Furthermore, it can promote airflow turbulence and reduce local dead zones and concentration polarization. A spacing range of 25mm to 35mm can provide sufficient structural support while avoiding airflow blockage caused by excessively small spacing.

[0229] For example, the distance L3 between two adjacent guide ribs 31 along the width direction of the guide plate 30 is 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, etc.
