[0082] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0083] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0084] Hereinafter, with reference to the accompanying drawings, an air conditioner according to a first aspect embodiment of the present invention will be described.

[0085] See Figures 1-4 The air conditioner 1000 includes a rear housing component 200 and a front panel component 100. The front panel component 100 is located on the front side of the rear housing component 200 and includes a panel assembly 10. The panel assembly 10 includes a panel bracket 1 and an exterior panel 2. The panel bracket 1 is assembled and connected to the rear housing component 200, and the exterior panel 2 is covered outside the panel bracket 1 and assembled and connected to the panel bracket 1.

[0086] In related technologies, the air conditioner 1000 typically includes a panel assembly 10 comprising a panel bracket 1 and an exterior panel 2. The exterior panel 2 usually serves as the main structure connecting to other components (e.g., top cover, chassis, display component 300, rear housing component 200), while the panel bracket 1 typically functions as an air duct fixed to the exterior panel 2 and does not serve as the main structure bearing loads or connecting other components. This leads to the following problems:

[0087] In terms of manufacturing, the exterior panel 2 serves as the main structure for connecting other components to the panel assembly 10. For example, when connecting to the rear box component 200, multiple connection and fixing structures need to be arranged on both sides of the exterior panel 2 along its length. The demolding method is a slanted ejector or a slider. Under the existing mold process conditions, after the exterior panel 2 is textured, dense stress marks easily appear on both sides, resulting in appearance defects on both sides of the exterior panel 2, which seriously affects the appearance of the product. In addition, the panel bracket 1 can only be attached to the exterior panel 2 and has some functions of air duct, but does not bear the function of bearing force and connecting other components. This results in the exterior panel 2 bearing more of the function of bearing force and connecting other components, which makes the shape of the exterior panel 2 subject to many connection structures and strength reinforcement structures, making it difficult to make very complex shapes.

[0088] Regarding product transportation, if the entire product is subjected to collisions or drops during transport and handling, the exterior panel 2, as the main connecting structure, will bear a significant impact, making it easy for its connections to other components to loosen, and the product to disintegrate during transportation. To solve the problem of insufficient connection strength, each connecting structure needs to be reinforced. However, as the exterior surface, reinforcing the connecting structures of the exterior panel 2 would result in many traces of the connecting structures appearing on the exterior surface, and the area of ​​the exterior surface would be significantly reduced.

[0089] In the technical solution of this application, by assembling and connecting the panel bracket 1 with the rear box component 200, and covering the panel bracket 1 with the exterior panel 2, which is also assembled and connected to the panel bracket 1, the panel bracket 1 serves as the main structure for connecting the panel assembly 10 to other components. The exterior panel 2 serves as an exterior decorative component, covering the panel bracket 1 and fixed to it. Since most of the connecting structures are located on the panel bracket 1, the number of connecting structures on the exterior panel 2 is significantly reduced. Therefore, the risk of appearance defects such as stress marks on the exterior panel 2 is significantly reduced, and the strength requirements for the exterior panel 2 itself are also greatly reduced. On the other hand, because the connecting structures on the panel bracket 1 are shielded by the exterior panel 2, the strength of the connecting structures can be increased without constraint, without considering the reduction in appearance area caused by excessive connecting structures. In summary, by using the panel bracket 1 as the main structure for connecting the panel assembly 10 to other components, the problems of appearance defects such as stress marks on the panel surface and insufficient strength of the connecting structures are solved.

[0090] Furthermore, the panel bracket 1 is no longer limited to the structure of the air duct; it can also be part of the appearance design. Its structure is more complex and varied than that of the appearance panel 2, which improves the malleability of the product design, making the product design more novel and unique, and enhancing the product's competitiveness in the market.

[0091] In the embodiments of this application, the panel bracket 1 is assembled and connected to the rear box component 200, and the exterior panel 2 is assembled and connected to the panel bracket 1. Assembly connection means that the two are two separate parts that are connected together by assembly, such as screw connection, snap connection, welding, etc.

[0092] For example, such as Figure 5 As shown, multiple hook-shaped buckles and side positioning pins are arranged on both sides of the panel bracket 1, and the rear box component 200 is correspondingly provided with a retaining plate 203 and a positioning groove. Pre-positioning is achieved by the side positioning pins and positioning grooves, and then the hook-shaped buckles are assembled and connected to the retaining plate 203.

[0093] In the embodiments of this application, the panel support 1 has an air outlet 11. The air outlet 11 can be a separate component or it can be formed on the panel support 1, that is, the panel support 1 is an integrated component. For example, the panel support 1 can be a one-piece molded part, that is, made of a single material without any detachable parts. Or, for another example, the panel support 1 can include multiple parts (such as the side frame part 12, the top frame part 13, the bottom frame part 15, etc. below). These multiple parts can be processed separately during the manufacturing process, but they are tightly joined together by a fixing and connecting process (such as bonding, welding, etc.) to form an inseparable whole.

[0094] In the embodiments of this application, the appearance panel 2 is placed over the panel support 1, meaning that the appearance panel 2 covers the outside of the panel support 1. However, this does not mean that the appearance panel 2 completely encloses the panel support 1. That is, the appearance panel 2 can partially or completely cover the outside of the panel support 1. The appearance panel 2 partially covering the outside of the panel support 1 can both shield the various connection structures on the panel support 1 from being exposed to the user's field of vision, thereby improving the user experience, and not hinder the connection between the panel support 1 and other components, thereby improving the connection strength. It is worth noting that the appearance panel 2 being placed over the panel support 1 does not mean that the appearance panel 2 is perfectly matched with the panel support 1. The appearance panel 2 simply covers or wraps around the panel support 1, and the appearance panel 2 can have its own shape. In addition, it does not mean that the appearance panel 2 is also a one-piece molded part. The appearance panel 2 can be formed by combining multiple components (such as the side panel 21, top plate 22, bottom plate 23, etc. mentioned below) to form the cover over the panel support 1.

[0095] In some embodiments of this application, the panel bracket 1 has an air outlet 11, and the front panel component 100 further includes an air guide assembly 20, which is installed on the panel component 10 and located at the air outlet 11. This simplifies the installation of the air guide assembly 20 and allows for adjustment of the airflow effect.

[0096] In the embodiments of this application, the air guide component 20 is installed on the panel component 10 and located at the air outlet 11. This does not mean that the air guide component 20 is necessarily installed on the panel bracket 1. The air guide component 20 can also be installed on the appearance panel 2, or it can be connected by clamping and fixing the panel bracket 1 and the appearance panel 2.

[0097] In some embodiments, see Figure 4 The panel bracket 1 includes two side bracket portions 12, with an air outlet 11 defined between the two side bracket portions 12. The upper end of the side bracket portion 12 is higher than the air guide assembly 20, and the lower end of the side bracket portion 12 is lower than the air guide assembly 20. This facilitates the processing and forming of the air outlet 11. Simultaneously, the length of the side bracket portion 12 extends vertically, with the upper end of the side bracket portion 12 higher than the air guide assembly 20 and the lower end of the side bracket portion 12 lower than the air guide assembly 20. Combined with the air guide assembly 20 being installed on the panel assembly 10 and positioned at the air outlet 11, the length of the side bracket portion 12 is greater than the length of the air guide assembly 20. This allows the entire panel bracket 1 to provide fixation and support for the installation of the air guide assembly 20, improving the structural strength of the panel assembly 10.

[0098] In some embodiments, the panel bracket 1 includes two side bracket portions 12, the length of which extends in the vertical direction and the width of which extends in the front-rear direction, and the rear end of the side bracket portion 12 is assembled and connected to the rear housing component 200; the exterior panel 2 includes two side panels 21, which respectively cover the outer sides of the two side bracket portions 12.

[0099] In the above technical solution, by setting side brackets 12 on both sides of the panel bracket 1, the air outlet 11 is stably fixed and supported, which improves the overall structural strength and safety of the air conditioner 1000.

[0100] Furthermore, the side bracket 12 provides space for the connection structure between the panel bracket 1 and the rear housing component 200, thereby improving the connection strength between them. The rear end of the side bracket 12 is connected to the rear housing component 200, which is convenient and quick and does not occupy the space of other panel brackets 1. The two side panels 21 cover the outer sides of the two side brackets 12 respectively, which can cover the connection structure on the side bracket 12 and form the side appearance of the air conditioner 1000, making the appearance of the air conditioner 1000 more concise.

[0101] In the embodiments of this application, the length of the panel bracket 1 in the vertical direction can extend from the top of the air conditioner 1000 to the bottom of the air conditioner 1000, or from the top of the air conditioner 1000 to the bottom of the air guide assembly 20, or from the top of the air guide assembly 20 to the bottom of the air conditioner 1000.

[0102] For example, such as Figure 3 As shown, the air conditioner 1000 can comprise three areas in the vertical direction: an upper panel area, an air outlet 11, and a lower panel 50 area. The upper and lower panel 50 areas can serve as mounting areas for components such as the display component 300, the access port for the electrical control components, and the mounting plate for the air outlet grille 30. When the panel bracket 1 extends from the top to the bottom of the air conditioner 1000, all three areas are located on the panel bracket 1. When the length of the panel bracket 1 is from the top of the air conditioner 1000 to the bottom of the air guide assembly 20, the upper panel area and the air outlet 11 are located on the panel bracket 1. When the length of the panel bracket 1 is from the top of the air guide assembly 20 to the bottom of the air conditioner 1000, the lower panel 50 area and the air outlet 11 are located on the panel bracket 1. Therefore, the length of the panel bracket 1 can be flexibly set to meet the needs of different installation methods, improving the adaptability of the panel bracket 1.

[0103] In some embodiments, combined with Figure 4 and Figure 5 The upper end of the side bracket 12 extends to face the upper end of the rear housing component 200. The panel bracket 1 includes a top bracket 13, which connects the upper ends of the two side brackets 12 and faces the upper end of the rear housing component 200. Thus, the upper part of the panel bracket 1 forms a more stable frame structure, which helps to improve the overall integrity and stability of the air conditioner 1000. In addition, a connection structure with the top cover component 500 can be provided on the top bracket 13 to strengthen the overall connection of the air conditioner 1000. The exterior panel 2 also includes a top plate 22, which is located above the top bracket 13. The top plate 22 not only covers and protects the internal components but also effectively prevents the intrusion of external factors such as dust and moisture, thus protecting the safety of the internal components.

[0104] In some embodiments, combined with Figure 4 and Figure 5The lower end of the side frame portion 12 extends to face the lower end of the rear housing component 200. The panel bracket 1 includes a base frame portion 15, which connects the lower ends of the two side frame portions 12 and faces the lower end of the rear housing component 200. This creates a more stable frame structure at the bottom of the panel bracket 1, improving the overall integrity and stability of the air conditioner 1000. Furthermore, a connection structure to the chassis component 400 can be provided on the base frame portion 15 to strengthen the overall connection of the air conditioner 1000. The exterior panel 2 also includes a base plate 23, located below the base frame portion 15. The base plate 23 further enhances the protection of the bottom of the equipment, effectively preventing external factors such as dust and moisture from corroding the internal components. Simultaneously, the base plate 23 also provides sound insulation and vibration damping, improving the user experience.

[0105] In some embodiments, combined with Figure 4 and Figure 5 The upper end of the side frame portion 12 extends to be opposite to the upper end of the rear box component 200. The panel bracket 1 includes a top frame portion 13, which is connected between the upper ends of the two side frame portions 12. The exterior panel 2 also includes a top plate 22, which is located above the top frame portion 13. The lower end of the side frame portion 12 extends to be opposite to the lower end of the rear box component 200. The panel bracket 1 includes a bottom frame portion 15, which is connected between the lower ends of the two side frame portions 12. The exterior panel 2 also includes a bottom plate 23, which is located below the bottom frame portion 15.

[0106] In the above technical solution, the panel bracket 1 includes two side bracket portions 12, a top bracket portion 13 connected between the two side bracket portions 12, and a bottom bracket portion 15, forming a stable cuboid structure that provides stable protection for the components installed therein; it also provides a good connection foundation for other components connected to it, which helps to improve the overall connection strength of the air conditioner 1000. In addition, when the exterior panel 2 also has side panels 21, a top plate 22, and a bottom plate 23, it can be fitted onto the outside of the cuboid structure of the panel bracket 1, achieving all-round coverage of the panel bracket 1.

[0107] In the embodiments of this application, the top plate 22 is disposed above the top frame portion 13 and the bottom plate 23 is disposed below the bottom frame portion 15. Here, "disposed of" can mean directly installed or there is a certain gap (such as for installing sealing strips, heat sinks, etc.).

[0108] In the embodiments of this application, the upper end of the side frame portion 12 extends to be front-to-back opposite to the upper end of the rear housing component 200, and the lower end of the side frame portion 12 extends to be front-to-back opposite to the lower end of the rear housing component 200. Here, "front-to-back opposite" means that the upper and lower ends are aligned in position, forming a continuous plane or near-plane structure. It can be completely flush or have a slight height difference.

[0109] In some embodiments, combined with Figures 6-8 The side panel 21 has a first connecting structure 211 at its rear, and the side frame 12 has a second connecting structure 123 at its rear. The second connecting structure 123 overlaps with the first connecting structure 211 in the front-rear direction. A first fastener 96 passes through one of the first connecting structure 211 and the second connecting structure 123 from rear to front and connects to the other. Thus, the front-rear overlap and fastener fixation effectively enhance the connection strength between the side panel 21 and the side frame 12, improving the stability of the overall structure. The front-rear overlap connection increases the contact area between the side panel 21 and the side frame 12, thereby improving the stability and load-bearing capacity of the overall structure. Furthermore, the overlap connection structure makes the assembly process simpler and faster, reducing assembly difficulty and cost.

[0110] In some embodiments, combined with Figures 6-8 The side panel 21 has a first positioning structure 213, and the rear of the side frame 12 has a second positioning structure 124. The first positioning structure 213 and the second positioning structure 124 are pre-positioned by insertion in the front-rear direction. Thus, by inserting the positioning structures, the side panel 21 and the side frame 12 can be pre-positioned before formal fixing. Even if there are certain operational errors during assembly, the positioning structures can play a certain role in tolerance and correction, thereby reducing the impact of assembly errors on the overall structure and ensuring their accurate relative positions during assembly, thereby improving the assembly precision of the entire structure. After pre-positioning, the side panel 21 and the side frame 12 can maintain a more stable relative position during subsequent fixing, which is beneficial for subsequent installation and the stability of the overall structure.

[0111] In some embodiments, combined with Figures 6-8 The side panel 21 has a first connecting structure 211 at its rear, and the side frame 12 has a second connecting structure 123 at its rear. The second connecting structure 123 overlaps with the first connecting structure 211 in the front-rear direction. A first fastener 96 passes through one of the first connecting structure 211 and the second connecting structure 123 from rear to front and connects with the other. The side panel 21 has a first positioning structure 213, and the side frame 12 has a second positioning structure 124 at its rear. The first positioning structure 213 and the second positioning structure 124 are pre-positioned by insertion in the front-rear direction. This enables rapid positioning and installation of the side panel 21 and the side frame 12, improving assembly efficiency.

[0112] For example, combined Figures 6-8The first positioning structure 213 is designed as a positioning pin, and the second positioning structure 124 is designed as a positioning hole slightly larger than the positioning pin. During pre-positioning, the positioning pin on the side panel 21 is inserted into the positioning hole on the side bracket 12. Since the positioning hole is slightly larger than the positioning pin, the relative positional relationship between the side panel 21 and the side bracket 12 can be finely adjusted during the subsequent fixing process. This achieves both the pre-positioning function and the ability to fine-tune to improve the assembly accuracy of the side panel 21 and the side bracket 12. The second connecting structure 123 is designed as a threaded hole, and the first connecting structure 211 is designed as a threaded post that matches the hole. The first fastener 96 is a self-tapping screw, which passes through the threaded hole on the side bracket 12 and is threadedly connected to the threaded post on the side panel 21. This enables rapid positioning and installation of the side panel 21 and the side bracket 12, improving assembly efficiency.

[0113] In some embodiments, see Figure 2 The panel bracket 1 has an air outlet 11, and the front panel component 100 also includes an air outlet grille 30, which covers the front side of the air outlet 11 and is installed on the panel bracket 1. As an air outlet, the air outlet grille 30 effectively guides airflow, reduces airflow resistance, and thus improves the airflow efficiency of the equipment. As part of the front panel component 100, the air outlet grille 30 is firmly connected to the panel bracket 1, enhancing the structural stability of the entire front panel component 100. Furthermore, the air outlet grille 30, covering the front side of the air outlet 11, provides protection, preventing external objects from directly contacting the air outlet 11 and extending its service life.

[0114] In the embodiments of this application, the air vent grille 30 can be detachable and connected to the panel bracket 1 via clips or fasteners. This facilitates the user's removal and replacement of the air vent grille 30 as needed, and also aids in cleaning and maintenance. Furthermore, the air vent grille 30 can be integrated with the front panel component 100, meaning the air vent grille 30 is formed or fixed together directly during manufacturing as part of the front panel component 100. This simplifies the assembly process and improves the stability and aesthetics of the overall structure.

[0115] In some embodiments, combined with Figure 2 and Figure 3The front panel component 100 also includes a display panel 40, which is located above the air outlet grille 30. The display panel 40 is mounted on the panel bracket 1, and its height is aligned with the user's line of sight. This allows the display panel 40 to clearly display the information of the display component 300 (such as temperature, humidity, and operating mode), facilitating user observation of the information on the display panel 40 and providing a more intuitive understanding of the device's operating status, thus enhancing the device's intelligence and user experience. The panel bracket 1 has a clearance opening 14 corresponding to the display panel 40. The air conditioner 1000 also includes a display component 300, which is mounted on the panel bracket 1 and opposite the clearance opening 14. Therefore, the clearance opening 14 provides installation space for the display component 300 while avoiding interference with the display panel 40, allowing the display panel 40 to remain on the same continuous surface as the air outlet grille 30 without protruding from other front panel components 100.

[0116] In some embodiments, combined with Figure 2 and Figure 3 The front panel component 100 also includes a lower panel 50. The panel bracket 1 includes a limiting structure located below the air vent grille 30 and cooperating with the air vent grille 30. The lower panel 50 is located below the air vent grille 30 and covers the limiting structure. The lower panel 50 is detachably mounted on the panel bracket 1.

[0117] In the above technical solution, the limiting structure on the panel bracket 1 cooperates with the limiting structure of the air outlet grille 30 to ensure the stable installation of the air outlet grille 30 on the panel bracket 1, avoiding shaking or falling off due to wind pressure or other external forces, thereby improving the overall structural stability and durability of the air conditioner 1000. In addition, the lower panel 50 is detachably installed on the panel bracket 1, allowing users or maintenance personnel to easily remove the lower panel 50 and control the limiting structure of the air outlet grille 30 to install or remove the air outlet grille 30 for cleaning, repair, or replacement, without having to disassemble the entire front panel component 100, thereby reducing maintenance costs and time.

[0118] In some embodiments, combined with Figure 2 and Figure 3The front panel component 100 also includes a display panel 40, which is located above the air outlet grille 30 and is mounted on a panel bracket 1. The panel bracket 1 has a clearance opening 14 corresponding to the display panel 40. The air conditioner 1000 also includes a display component 300, which is mounted on the panel bracket 1 and faces the clearance opening 14. The front panel component 100 also includes a lower panel 50. The panel bracket 1 includes a limiting structure located below the air outlet grille 30 and engaging with it. The lower panel 50 is located below the air outlet grille 30 and blocks the limiting structure. The lower panel 50 is detachably mounted on the panel bracket 1. Therefore, the air conditioner 1000 includes a display panel 40, an air outlet grille 30, and a lower panel 50 in the vertical direction. The display component 300 of the air conditioner 1000 has a suitable height, and the air outlet grille 30 has a large air outlet area from top to bottom and is easy to install and remove, improving the user experience.

[0119] In some embodiments, see Figure 4 The air guide assembly 20 includes an air guide plate 51, which extends along the vertical direction in the length direction. The upper and lower shaft ends of the air guide plate 51 are rotatably mounted on the panel bracket 1. The exterior panel 2 is open at the corresponding air guide plate 51, or the exterior panel 2 includes a structure that is opposite to the air guide plate 51 in front and back, and the structure is located on the rear side of the air guide plate 51.

[0120] In the above technical solution, the air guide plate 51 can rotate around its upper and lower shaft ends, thereby changing the air outlet direction to meet the user's needs for different air supply angles, improving the comfort and practicality of the air conditioner 1000. By adjusting the angle of the air guide plate 51, the wind speed and airflow distribution can also be affected, making the air supply of the air conditioner 1000 more uniform, reducing the feeling of direct blowing, and improving the user experience. The appearance panel 2 is open at the corresponding air guide plate 51, which does not hinder the installation of the air guide plate 51, making the entire air guide assembly 20 compact in structure and occupying little space, which is conducive to the miniaturization and weight reduction of the air conditioner 1000.

[0121] In some embodiments, see Figure 4 At least one of the panel support 1 and the appearance panel 2 includes a crossbeam A, the length direction of which extends in the left-right direction; the panel assembly 10 includes a pressure strip 3, the length direction of which extends in the left-right direction, and the pressure strip 3 is disposed on the front side of the crossbeam A; the air guide assembly 20 includes an air guide plate 51, the length direction of which extends in the up-down direction and includes a vertical shaft portion 511, the vertical shaft portion 511 being pivotally clamped between the crossbeam A and the pressure strip 3.

[0122] In the above technical solution, the crossbeam A serves as a supporting structure, providing a stable support foundation for the air guide plate 51. Simultaneously, the pressure strip 3 further enhances the stability of the air guide plate 51 in its installation position, preventing it from shaking or falling off during use. The air guide plate 51 is pivotally clamped between the crossbeam A and the pressure strip 3 via the vertical shaft 511, allowing the angle of the air guide plate 51 to be adjusted, thereby changing the air outlet direction and speed of the air conditioner 1000, improving comfort and convenience of use. Furthermore, since the air guide plate 51 is installed between the crossbeam A and the pressure strip 3 using a clamping method, no complex connectors or installation steps are required, making installation and maintenance simpler and faster.

[0123] In the embodiments of this application, at least one of the panel support 1 and the appearance panel 2 includes a crossbeam A. The length direction of the crossbeam A extends in the left-right direction. The position of the crossbeam A in the panel support 1 or the appearance panel 2 is not limited. It can be located at the upper, middle or lower part of the panel support 1 or the appearance panel 2. When the crossbeam A is located at the middle part of the panel support 1 or the appearance panel 2, the vertical axis 511 is located at the center of mass of the air guide plate 51. The crossbeam A can better clamp the air guide plate 51, and the rotation of the air guide plate 51 is also smoother.

[0124] In some embodiments, combined with Figures 9-13 The panel assembly 10 also includes a decorative cover 4, which covers the front side of the pressure plate strip 3. The decorative cover 4 has a rearwardly protruding snap-fit ​​portion 41, and the pressure plate strip 3 has a snap-fit ​​groove 32. The snap-fit ​​portion 41 and the snap-fit ​​groove 32 engage in a snap-fit ​​relationship. Thus, by covering the front side of the pressure plate strip 3, the decorative cover 4 conceals the pressure plate strip 3 and its connection details with the crossbeam A and the air guide plate 51, reducing dust accumulation in the pivot structure and preventing the air guide plate 51 from becoming stuck during rotation. This results in a cleaner and more aesthetically pleasing appearance for the equipment. The snap-fit ​​portion 41 on the decorative cover 4 engages with the snap-fit ​​groove 32 on the pressure plate strip 3, simplifying the assembly process and enhancing the connection stability between the decorative cover 4 and the pressure plate strip 3. The snap-fit ​​engagement allows the decorative cover 4 to be easily removed when needed, facilitating cleaning, inspection, or replacement of parts for the user. It also helps reduce maintenance costs and improve the maintainability of the equipment.

[0125] In some embodiments, combined with Figures 13-16The crossbeam A includes a first crossbeam 16 integrated into the panel bracket 1 and a second crossbeam 24 integrated into the exterior panel 2. The first crossbeam 16 defines a receiving groove 161 that opens to the front. The second crossbeam 24 is embedded in the receiving groove 161. The first crossbeam 16 has a first connecting portion 162. The second crossbeam 24 has a clearance hole 241 at the corresponding first connecting portion 162. The pressure strip 3 is provided on the front side of the second crossbeam 24. The pressure strip 3 has a second connecting portion 31 at the corresponding clearance hole 241. The second fastener 91 passes through the second connecting portion 31 and the clearance hole 241 from front to back and is connected to the first connecting portion 162.

[0126] In the above technical solution, the first crossbeam 16 is integrated into the panel bracket 1, and the second crossbeam 24 is integrated into the outer panel 2, and they are connected together by an embedded fit, making the structure of the panel assembly 10 more compact and the integration higher. This helps to reduce the number of parts, simplify the assembly process, and improve production efficiency. The receiving groove 161 on the first crossbeam 16 provides a precise positioning reference for the second crossbeam 24, ensuring that the second crossbeam 24 can be accurately and stably embedded in the receiving groove 161. At the same time, through the cooperation of the first connecting part 162, the clearance hole 241 and the second connecting part 31, and the connecting action of the second fastener 91, the assembly accuracy and stability of the panel assembly 10 are further improved. In addition, the second fastener 91 passes through the second connecting part 31 and the clearance hole 241 from front to back and connects to the first connecting part 162, so that the pressure strip 3, the second crossbeam 24 and related connecting parts can still be easily disassembled when needed for cleaning, inspection or replacement. Compared to the conventional method of installing the second fastener 91 from the back and forward, this method is easier to install and remove, and allows for a direct inspection of whether the panel bracket 1 and the exterior panel 2 are properly assembled through the interlocking of the first crossbeam 16 and the second crossbeam 24.

[0127] In the embodiments of this application, it is worth noting that the installation sequence of the first crossbeam 16, the second crossbeam 24, the pressure strip 3, and the second fastener 91 is not limited to the above sequence. Alternatively, the pressure strip 3 can be placed between the first crossbeam 16 and the second crossbeam 24, i.e., the sequence from front to back is the second fastener 91, the second crossbeam 24, the pressure strip 3, and the first crossbeam 16. In this way, a space is formed between the pressure strip 3 and the first crossbeam 16 to clamp the vertical shaft portion 511, which can more stably fix the air guide plate 51. Alternatively, the sequence can be from front to back: the pressure strip 3, the second fastener 91, the second crossbeam 24, and the first crossbeam 16. In this way, the pressure strip 3 also has the function of the decorative cover 4 mentioned above, which helps to reduce the number of installation parts and improve installation efficiency.

[0128] In some embodiments, combined with Figures 13-16The upper wall of the pressure strip 3 has a front upper retaining shaft portion 33, the lower wall of the pressure strip 3 has a front lower retaining shaft portion 34, the upper wall of the first crossbeam 16 has a rear upper retaining shaft portion 163, the lower wall of the first crossbeam 16 has a relief hole 164, and the lower wall of the second crossbeam 24 has a rear lower retaining shaft portion 242 through which the relief hole 164 passes downward. The front upper retaining shaft portion 33 and the rear upper retaining shaft portion 163 form an upper clamping structure B, and the front lower retaining shaft portion 34 and the rear lower retaining shaft portion 242 form a lower clamping structure C. The vertical shaft portion 511 is clamped by the upper clamping structure B and the lower clamping structure C, and the vertical shaft portion 511 has a shoulder structure 5111 that stops in the vertical direction between the upper clamping structure B and the lower clamping structure C.

[0129] In the above technical solution, the upper clamping structure B and the lower clamping structure C are respectively composed of the front upper clamping shaft part 33 and the rear upper clamping shaft part 163, and the front lower clamping shaft part 34 and the rear lower clamping shaft part 242. The upper clamping structure B and the lower clamping structure C provide double clamping for the vertical shaft part 511, enhancing the stability and reliability of the clamping. The vertical shaft part 511 is firmly clamped in the vertical direction, making it less prone to shaking or displacement. At the same time, no additional fasteners or connectors are required, simplifying the assembly process, improving production efficiency, facilitating disassembly and maintenance, and reducing maintenance costs. In addition, the cooperation between the clamping shaft part and the shoulder structure 5111 not only provides a stable clamping but also provides a certain degree of guidance for the rotation of the vertical shaft part 511, making the air guide plate 51 rotate more smoothly and steadily. The shoulder structure 5111 effectively stops the vertical shaft part 511 between the upper clamping structure B and the lower clamping structure C in the vertical direction, preventing excessive movement or detachment of the vertical shaft part 511 and improving the safety of the equipment.

[0130] The following describes a middle connection structure between an exterior panel 2 and a panel support 1, in conjunction with the above embodiments.

[0131] For example, combined Figures 8-16The air guide assembly 20 includes an air guide plate 51, which extends vertically along its length. The upper and lower shaft ends of the air guide plate 51 are rotatably mounted on the panel bracket 1. The air guide plate 51 has a vertical shaft portion 511 in its middle. The exterior panel 2 is open at the corresponding air guide plate 51. Both the panel bracket 1 and the exterior panel 2 have a crossbeam A, which is located in the middle of the panel bracket 1 and the exterior panel 2. The crossbeam A includes a first crossbeam 16 integrated into the panel bracket 1 and a second crossbeam 24 integrated into the exterior panel 2. The first crossbeam 16 extends horizontally along its length and connects between the two side frame portions 12. The second crossbeam 24 extends horizontally along its length and connects between the two side frame portions 12. Between the side panels 21, a first crossbeam 16 defines a receiving groove 161 that opens to the front. A second crossbeam 24 is embedded in the receiving groove 161. The first crossbeam 16 has a first connecting portion 162, which is a threaded post. The second crossbeam 24 has a clearance hole 241 corresponding to the first connecting portion 162. The panel assembly 10 includes a pressure strip 3, which extends horizontally along its length. The pressure strip 3 is located on the front side of the second crossbeam 24. The pressure strip 3 has a second connecting portion 31 corresponding to the clearance hole 241, which is a threaded hole. A second fastener 91 is a screw that passes through the threaded hole and the clearance hole 241 from front to back and is connected to the threaded post. Thus, the middle connection structure between the exterior panel 2 and the panel bracket 1 is compact, improving the assembly accuracy and stability of the panel assembly 10, and facilitating installation and disassembly.

[0132] The upper wall of the pressure strip 3 has a front upper retaining shaft portion 33, and the lower wall of the pressure strip 3 has a front lower retaining shaft portion 34. The upper wall of the first crossbeam 16 has a rear upper retaining shaft portion 163, and the lower wall of the first crossbeam 16 has a clearance hole 164. The lower wall of the second crossbeam 24 has a rear lower retaining shaft portion 242 through which the clearance hole 164 passes downward. The front upper retaining shaft portion 33 and the rear upper retaining shaft portion 163 form an upper clamping structure B, and the front lower retaining shaft portion 34 and the rear lower retaining shaft portion 242 form a lower clamping structure C. The vertical shaft portion 511 is clamped by the upper clamping structure B and the lower clamping structure C, and the vertical shaft portion 511 has two shoulders that stop in the vertical direction between the upper clamping structure B and the lower clamping structure C. Thus, the vertical shaft portion 511 is firmly clamped in the vertical direction and is not prone to shaking or displacement. Furthermore, the clamping structure provides guidance for the rotation of the vertical shaft 511, making the air guide plate 51 rotate more smoothly and steadily. The air guide plate 51 is pivotally clamped between the crossbeam A and the pressure strip 3 via the vertical shaft 511, allowing the angle of the air guide plate 51 to be adjusted, thereby changing the air outlet direction and air speed of the air conditioner 1000 and improving the comfort and convenience of use.

[0133] The panel assembly 10 also includes a decorative cover 4, which covers the front side of the pressure plate strip 3. The decorative cover 4 has a rearwardly protruding snap-fit ​​portion 41, and the pressure plate strip 3 has a snap-fit ​​groove 32. The snap-fit ​​portion 41 and the snap-fit ​​groove 32 engage with each other. Thus, by covering the front side of the pressure plate strip 3, the decorative cover 4 can conceal the connection details between the pressure plate strip 3, the crossbeam A, the second fastener 91, and the air guide plate 51, reducing the amount of dust falling into the pivot structure and causing the air guide plate 51 to become stuck during rotation. It also makes the appearance of the equipment cleaner and more aesthetically pleasing. The snap-fit ​​portion 41 on the decorative cover 4 and the snap-fit ​​groove 32 on the pressure plate strip 3 engage with each other, simplifying the assembly process and enhancing the connection stability between the decorative cover 4 and the pressure plate strip 3.

[0134] In some embodiments, see Figure 17 The panel support 1 includes a top bracket 13, and the exterior panel 2 includes a top plate 22, which covers the top bracket 13 and is fixedly connected to it. Thus, the top bracket 13 and the top plate 22, through this fixed connection, form a robust support structure, enhancing the structural strength of the entire panel assembly 10 and helping to resist external loads and vibrations. When the top plate 22 is subjected to impact, the top bracket 13 provides internal strength support, reducing the possibility of deformation and breakage at the top, and improving the durability and reliability of the air conditioner 1000.

[0135] In some embodiments, combined with Figures 17-19 The top frame 13 has a third connecting part 131 at its front end and a fourth connecting part 132 at its rear end. The top plate 22 has a recessed groove 221. The third connecting part 131 is located below the groove 221. The groove 221 has a fifth connecting part 222 corresponding to the third connecting part 131. The top plate 22 also includes a sixth connecting part 223 located in front of the fourth connecting part 132. The third fastener 92 passes through the fifth connecting part 222 from top to bottom and is connected to the third connecting part 131. The fourth fastener 93 passes through the fourth connecting part 132 from back to front and is connected to the sixth connecting part 223.

[0136] In the above technical solution, the third connecting part 131 and the fifth connecting part 222, and the fourth connecting part 132 and the sixth connecting part 223 are connected by fasteners, forming a multi-point fixed structure. This significantly enhances the connection stability between the top frame part 13 and the top plate 22, helps resist external loads and vibrations, and improves the overall structural strength of the equipment. By setting a recess 221 on the top plate 22, and setting the fifth connecting part 222 in the recess 221 and positioning the third connecting part 131 below the recess 221, the accuracy and reliability of the connection are improved. In addition, the recess 221 can also hide the connecting parts and fasteners to a certain extent, improving the aesthetics of the entire panel assembly 10.

[0137] In some embodiments, combined with Figures 17-19 The third connecting part 131 is provided in two parts, which are respectively located near the left and right ends of the top frame part 13. The fourth connecting part 132 is provided in two parts, which are respectively located near the left and right ends of the top frame part 13. The left and right sides of the top frame part 13 have multiple reinforcing columns 134 that protrude upward and are spaced apart in the front and back direction.

[0138] In the above technical solution, by providing two third connecting parts 131 and a fourth connecting part 132 at the left and right ends of the top frame part 13 respectively, the top plate 22 and the top frame part 13 are connected at multiple points, significantly enhancing the strength and stability of the entire structure. Furthermore, by placing the third connecting parts 131 and the fourth connecting parts 132 at the left and right ends of the top frame part 13 respectively, the connection points are more dispersed, avoiding the problem of excessive local stress caused by overly concentrated connections. This helps optimize the connection structure and improve the reliability and safety of the connection.

[0139] Multiple reinforcing columns 134 located at the left and right edges of the top frame section 13 further enhance the structural strength of the top frame section 13 and improve its resistance to deformation. The design of the reinforcing columns 134 helps to resist the compression and torsion of the top frame section 13 by external loads, maintaining the stability and integrity of the structure.

[0140] For example, combined Figures 17-19 The panel support 1 includes a top frame 13, and the exterior panel 2 includes a top plate 22. The top plate 22 covers the top frame 13. The front end of the top frame 13 has two third connecting parts 131, which are respectively located near the left and right ends of the top frame 13. The third connecting parts 131 are threaded posts, and cylindrical reinforcing posts 134 are sleeved on their exterior. The top plate 22 has a downwardly recessed groove 221. The threaded posts are located below the groove 221. The groove 221 has threaded holes corresponding to the threaded posts. The third fastener 92 is a screw that passes through the threaded holes from top to bottom and is connected to the threaded posts. The rear end of the top frame 13 has two fourth connecting parts 132, which are respectively located near the left and right ends of the top frame 13. The fourth connecting parts 132 are threaded holes. The top plate 22 also includes a sixth connecting part 223 located in front of the fourth connecting parts 132. The sixth connecting part 223 is a threaded post. The fourth fastener 93 is a screw that passes through the threaded holes from back to front and is connected to the threaded posts. The top frame 13 has three upward-protruding cylindrical reinforcing columns 134 spaced apart along the front-back direction at the left and right edges. This connects the top plate 22 and the top frame 13 at multiple dispersed points, significantly enhancing the strength and stability of the entire structure.

[0141] In some embodiments, combined with Figure 20 and Figure 21The panel bracket 1 includes a top bracket portion 13, and the rear side of the top bracket portion 13 has a rearwardly protruding extension portion 133, which is fixedly connected to the upper end of the rear housing component 200. Thus, the rearward protrusion of the extension portion 133 makes more efficient use of the internal space of the equipment, and the extension portion 133 creates a more stable connection structure between the top bracket portion 13 and the rear housing, effectively improving the stability and load-bearing capacity of the entire air conditioner 1000.

[0142] In some embodiments, combined with Figure 20 and Figure 21 The upper end of the rear box component 200 has a mating structure, and the extension 133 overlaps the mating structure. The mating structure includes a limiting protrusion 201 and a connecting post 202. A limiting hole 1331 and a connecting hole 1332 are formed on the extension 133. The limiting protrusion 201 extends upward into the limiting hole 1331, and the connecting post 202 is supported below the connecting hole 1332. The fifth fastener 94 passes through the connecting hole 1332 from top to bottom and is connected to the connecting post 202.

[0143] During installation, lift the panel bracket 1 upward so that the limiting hole 1331 in the extension 133 aligns with the limiting protrusion 201. Then lower the panel bracket 1 downward so that the limiting protrusion 201 extends upward into the limiting hole 1331 to complete the initial positioning and overlap. Then, insert the fifth fastener 94 from top to bottom through the connecting hole 1332 and connect it to the connecting post 202.

[0144] In the above technical solution, the cooperation between the limiting protrusion 201 and the limiting hole 1331 plays a positioning role, enabling the panel bracket 1 to accurately overlap with the rear box component 200, which helps to improve assembly accuracy and reduce errors and adjustment time during the assembly process. At the same time, the connecting post 202 is supported below the connecting hole 1332 and is fastened by the fifth fastener 94 passing through the connecting hole 1332 from top to bottom, further enhancing the stability of the connection.

[0145] In some embodiments, combined with Figure 22 and Figure 23 The rear end of the side frame 12 has a hook 121 and a limiting pin 122. The hook 121 protrudes rearward and the hook portion 1211 extends downward. The front end of the rear box component 200 has a locking plate 203 and a limiting groove 205. The locking plate 203 defines a locking hole 204. The limiting groove 205 includes an upper groove 2051 and a lower groove 2052 arranged sequentially from top to bottom. The transverse groove width of the lower groove 2052 is smaller than the transverse groove width of the upper groove 2051. The hook 121 extends rearward into the locking hole 204 and downward so that the hook portion 1211 stops on the rear side of the locking plate 203. The limiting pin 122 extends rearward into the limiting groove 205 and downward so as to cooperate with the lower groove 2052 in a transverse limiting manner.

[0146] During installation, the panel bracket 1 is lifted upwards, aligning the limiting pin 122 with the upper groove 2051 of the limiting slot 205, and the hook 121 with the locking hole 204 on the locking plate 203, completing the initial positioning. Then, the panel bracket 1 is lowered downwards, and the limiting pin 122 slides down into the lower groove 2052 of the limiting slot 205. The hook portion 1211 of the hook 121 stops at the rear side of the locking plate 203, forming a stable locking relationship. This achieves the connection between the side bracket portion 12 of the panel bracket 1 and the rear housing component 200. The cooperation of the hook 121 and the limiting pin 122 with the locking plate 203 and the limiting groove 205 provides positioning, making precise alignment easier to achieve during installation and reducing installation errors. The cooperation between the hook 121 and the plate 203, and the limiting pin 122 and the limiting groove 205, forms a stable connection between the side frame 12 and the rear housing component 200, which can effectively resist external loads and vibrations and ensure the stable connection of all components of the air conditioner 1000.

[0147] In some embodiments, combined with Figures 24-28 The air conditioner 1000 also includes a chassis component 400, which is located below the front panel component 100 and the rear housing component 200, and the panel bracket 1 is fixedly connected to the chassis component 400. Thus, the chassis component 400, as the bottom support structure of the entire air conditioner 1000, effectively enhances the structural stability of the entire device through its fixed connection with the panel bracket 1, making the air conditioner 1000 more stable during installation and use, and reducing the risk of loosening or damage caused by vibration or external forces.

[0148] In some embodiments, combined with Figures 24-28 The panel bracket 1 includes a base frame 15, and the exterior panel 2 includes a base plate 23. The base plate 23 is located below the base frame 15. The rear part of the base frame 15 has a downwardly protruding first positioning pin 151. The base plate 23 has a hollow hole 231 corresponding to the first positioning pin 151. The front part of the base plate 23 has a downwardly protruding second positioning pin 232. The chassis component 400 includes a top-open first positioning hole 401 and a second positioning hole 402. The first positioning pin 151 is positioned downwardly in the first positioning hole 401, and the second positioning pin 232 is positioned downwardly in the second positioning hole 402. The lower front side of the panel bracket 1 has a mounting part 17. The chassis component 400 includes an upwardly protruding boss part 403. The boss part 403 is located behind the mounting part 17. The sixth fastener 95 passes through the mounting part 17 from front to back and is connected to the boss part 403.

[0149] In the above technical solution, the panel bracket 1 includes a base frame 15, while the exterior panel 2 includes a base plate 23 located below the base frame 15. This allows the panel bracket 1 and the exterior panel 2 to be structurally more tightly integrated, improving the connection stability of the panel assembly 10. The rear of the base frame 15 has a downwardly protruding first positioning pin 151, and the base plate 23 has a corresponding perforated hole 231, allowing the first positioning pin 151 to pass through and engage with the first positioning hole 401 on the chassis component 400. This ensures precise positioning of the panel assembly 10 and the chassis component 400 in the front-rear direction. The front of the base plate 23 has a downwardly protruding second positioning pin 232, which engages with the second positioning hole 402 on the chassis component 400, further enhancing the connection stability between the panel assembly 10 and the chassis component 400, helping to reduce assembly errors and ensuring the overall performance of the air conditioner 1000. Furthermore, the first positioning pin 151 and the second positioning pin 232 at both ends of the chassis component 400 in the front-rear direction also improve the stability of the air conditioner 1000, allowing the air conditioner 1000 to stand more stably. A mounting portion 17 is provided on the lower front side of the panel bracket 1, while the chassis component 400 includes an upwardly protruding boss portion 403. The mounting portion 17 is located on the front side of the boss portion 403, facilitating the sixth fastener 95 (such as screws, bolts, etc.) to pass through the mounting portion 17 from front to back and connect with the boss portion 403, thus achieving a firm fixation between the panel bracket 1 and the chassis component 400. This makes the air conditioner 1000 more stable during operation and reduces shaking caused by vibration or load changes.

[0150] During assembly, firstly, ensure that the first locating pin 151 and the second locating pin 232 are accurately inserted into the first locating hole 401 and the second locating hole 402 on the chassis component 400, respectively, to achieve initial positioning. Then, pass the sixth fastener 95 from front to back through the mounting part 17 and connect it to the boss part 403 to achieve final fixation. Thus, the cooperation of the locating pins, the mounting part 17, and the boss part 403 ensures the precise connection and stability between the panel bracket 1 and the chassis component 400.

[0151] In some embodiments, combined with Figure 24 and Figure 28 The front panel component 100 also includes a cover 60, which covers the front side of the mounting part 17 and the sixth fastener 95 and is detachably connected to the mounting part 17.

[0152] In the above technical solution, the cover 60 effectively covers the front side of the mounting part 17 and the sixth fastener 95, avoiding direct exposure of the internal structure such as the fastener, preventing it from being corroded by the external environment (such as moisture, dust, etc.), thereby extending the service life of the fastener and ensuring the stability of the connection.

[0153] The detachable connection between the cover 60 and the mounting part 17 allows the user to easily remove the cover 60 and then remove the sixth fastener 95 when maintenance or replacement of parts is required. This ensures both convenience for daily use and operability during maintenance.
