Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a ceiling-mounted air conditioner. Background Technology

[0002] Air conditioners are common household appliances. They are categorized into floor-standing, wall-mounted, and ceiling-mounted types based on their installation method. Ceiling-mounted air conditioners, installed in the ceiling, make full use of ceiling space and are therefore widely used.

[0003] A ceiling-mounted air conditioner in the prior art includes a panel assembly comprising a panel and a grille. An air inlet is located at the center of the panel, and a filter is installed at the air inlet. The grille is mounted on the panel to cover the filter. A locking structure is provided on one side of the grille, and a hook structure is provided on the opposite side. To remove the grille, the locking structure is first released. The locking structure has a reset component, and the user must continuously apply force to the locking structure during disassembly. Then, the grille is suspended below the panel via the hook structure. A suspension rope is installed between the grille and the panel to prevent the grille from falling. The entire disassembly process requires the user's hands, making it inconvenient and inefficient.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] In view of the problems pointed out in the background art, this utility model proposes a ceiling-mounted air conditioner that facilitates the installation and removal of the grille panel.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] In some embodiments of this application, a ceiling-mounted air conditioner is provided, wherein an installation opening is formed at the bottom of the outer casing; a heat exchanger is disposed in the outer casing; a fan is located in the air inlet channel; the panel assembly includes a panel, a grille, and a locking assembly, the panel is disposed at the bottom of the outer casing and covers the installation opening, and the panel is provided with an air inlet and a limiting part; the grille is disposed at the bottom of the panel and covers the air inlet; the locking assembly includes a locking movable member and a locking part; the locking movable member is slidably disposed on the grille, and the locking movable member is configured to move toward the panel to cooperate with the limiting part, and the locking movable member is also configured to move away from the panel to disengage from the limiting part; the locking part is configured to lock the locking movable member in the position cooperating with the limiting part to connect the panel and the grille.

[0008] The above technical solution has the following advantages or beneficial effects: The locking assembly of this application is disposed on the grating plate. The locking assembly includes a locking movable part and a locking part. The locking movable part is slidably disposed on the grating plate. By manually moving the locking movable part, the locking movable part moves horizontally. After the locking movable part moves horizontally towards the panel under the manual action, the locking movable part cooperates with the limiting part. At this time, the locking part locks the locking movable part in the position that cooperates with the limiting part, thereby initially fixing the grating plate to the panel. When disassembling the grating plate, the locking movable part is moved by hand to release the limiting part of the locking movable part. The locking movable part moves horizontally away from the panel, and the locking movable part disengages from the limiting part, thus releasing the connection between the grating plate and the panel.

[0009] The locking assembly of this application achieves automatic locking after the moving part of the locking mechanism is pushed into place through a locking part.

[0010] The locking assembly of this application eliminates the spring. When disassembling the grating, after the locking movable part disengages from the limiting part, it is not necessary to continuously apply force to the locking movable part by hand. At this time, it is convenient for the user to use both hands to disassemble the snap-fit ​​structure between the grating and the panel, which facilitates the disassembly of the grating.

[0011] In some embodiments of this application, the grating plate is provided with an opening, and the latching movable member includes a latching horizontal portion and a latching vertical portion. The latching vertical portion protrudes downward through the opening, and the latching horizontal portion is slidably connected to the grating plate. The latching horizontal portion is configured to move above the limiting portion to limit the limiting portion between the latching horizontal portion and the grating plate.

[0012] The above technical solution has the following advantages or beneficial effects: the opening extends a certain distance along the movement direction of the locking mechanism, increasing the movement space for the locking mechanism. The vertical part of the locking mechanism protrudes downward from the opening for the user to manually operate. After the horizontal part of the locking mechanism moves horizontally towards the panel and into position, the locking part locks the horizontal part of the locking mechanism in that position. The horizontal part of the locking mechanism is located above the limiting part, thereby limiting the limiting part between the horizontal part of the locking mechanism and the grille plate. In this way, the initial fixed installation between the grille plate and the panel is achieved.

[0013] In some embodiments of this application, the grating plate is provided with a mounting post, the horizontal portion of the latch is provided with an opening, the opening extends along the movement direction of the horizontal portion of the latch, and the mounting post passes through the opening.

[0014] The above technical solution has the following advantages or beneficial effects: when the locking movable part is moved, the mounting column moves along the opening, which plays a guiding role for the locking movable part, and at the same time realizes the sliding installation of the locking movable part on the grating plate.

[0015] In some embodiments of this application, the locking assembly further includes a locking limiting member, which is fixedly installed to the mounting post via a connector. The locking limiting member is configured to restrict the upward displacement of the movable locking member and covers the opening.

[0016] The above technical solution has the following advantages or beneficial effects: while limiting the locking and moving parts, the locking and limiting parts also cover the opening to prevent indoor air from flowing into the air conditioner through the opening.

[0017] In some embodiments of this application, the locking limiting member includes a transverse wall, which is fixedly installed to the mounting post by a connector. Side walls are provided on opposite sides of the transverse wall, and a first protrusion is provided on the side wall.

[0018] A second protrusion is provided on the side wall of the horizontal portion of the latch. The second protrusion abuts against the first protrusion and is located on the side of the first protrusion closer to the panel, so that the latch movable member is locked in the position that cooperates with the limiting portion.

[0019] The above technical solution has the following advantages or beneficial effects: When the latch assembly is in the unlocked position, the second protrusion is located on the side of the first protrusion away from the panel. When installing the grille, the latching movable part is moved towards the panel, and the second protrusion passes over the first protrusion. The second protrusion is located on the side of the first protrusion closer to the panel, and the second protrusion abuts against the first protrusion. At this time, the latching movable part is locked in this position by the limiting effect of the first protrusion on the second protrusion, that is, the latching movable part is locked in the position that cooperates with the limiting part.

[0020] In some embodiments of this application, the side wall of the latch limiting member is further provided with a third protrusion, the third protrusion being spaced apart from the first protrusion, the third protrusion being located on the side of the first protrusion away from the panel, and the third protrusion being configured to limit the movement distance of the latching member in the direction away from the panel.

[0021] The above technical solution has the following advantages or beneficial effects: When disassembling the grille, the locking mechanism is moved away from the panel, and the locking mechanism disengages from the limiting part. The second protrusion passes over the first protrusion, and the second protrusion is located between the first protrusion and the third protrusion. The third protrusion blocks the second protrusion, which on the one hand limits the movement distance of the locking mechanism away from the panel, and on the other hand provides an operation prompt to the user, indicating that the locking mechanism has disengaged from the limiting part.

[0022] In some embodiments of this application, two locking assemblies are provided, and the two locking assemblies are arranged opposite to each other on the grid plate.

[0023] The above technical solution has the following advantages or beneficial effects: the grating is initially fixed on the panel by two locking components, preventing the grating from falling off.

[0024] In some embodiments of this application, the panel and the grille are detachably snapped together.

[0025] The above technical solution has the following advantages or beneficial effects: the panel and the grating are connected by a snap-fit ​​structure, eliminating screws and improving the efficiency of grating assembly and disassembly. Furthermore, since the snap-fit ​​assembly eliminates the spring, when disassembling the grating, after the snap-fit ​​moving part disengages from the limiting part, it is not necessary to continuously apply force to the snap-fit ​​moving part by hand. This allows the user to easily disassemble the snap-fit ​​structure between the grating and the panel using both hands, facilitating grating removal.

[0026] In some embodiments of this application, a ceiling-mounted air conditioner is provided, wherein an installation port is formed at the bottom of the outer casing; a heat exchanger is configured to perform heat exchange treatment on the flowing air, the heat exchanger is disposed in the outer casing; an air supply channel is formed between the heat exchanger and the inner wall of the outer casing, and an air inlet channel is formed around the heat exchanger; a fan is located in the air inlet channel;

[0027] The air conditioner also includes a panel assembly, which includes:

[0028] A panel is disposed at the bottom of the housing and covers the mounting port. An air inlet is provided on the panel, which communicates with the air inlet channel. A limiting part is provided on the panel.

[0029] A grille, wherein the grille is disposed at the bottom of the panel and covers the air inlet;

[0030] The locking assembly includes:

[0031] A locking member is slidably disposed on the grille plate. The locking member is configured to move toward the panel to engage with the limiting portion, and the locking member is also configured to move away from the panel to disengage from the limiting portion.

[0032] A locking limit member is fixedly disposed on the grating plate. The locking limit member is configured to restrict the upward displacement of the locking movable member. The locking limit member is also configured to lock the locking movable member in a position that cooperates with the limiting part, so as to connect the panel to the grating plate.

[0033] The above technical solution has the following advantages or beneficial effects: The locking assembly of this application includes a locking movable component and a locking limiting component. The locking movable component is slidably disposed on the grating plate. By manually moving the locking movable component, it moves horizontally. After the locking movable component moves horizontally towards the panel under the manual action, it engages with the limiting part on the panel. At this time, the locking movable component is locked in the position engaging with the limiting part by the locking limiting component, thereby initially fixing the grating plate to the panel. When disassembling the grating plate, the locking movable component is manually moved to release the limiting component from the locking movable component. The locking movable component moves horizontally away from the panel, disengaging from the limiting part and releasing the connection between the grating plate and the panel.

[0071] The ceiling-mounted air conditioner in this application typically includes a housing 1 and a heat exchanger 2, a fan 3, and a water collection tray disposed within the housing 1. The heat exchanger 2 has an annular structure to surround the outside of the fan 3, and the surrounding of the heat exchanger 2 forms an air inlet channel 51. An air supply channel 52 is formed between the heat exchanger 2 and the inner wall of the housing 1. The water collection tray is located at the bottom of the heat exchanger 2 to collect the condensate from the heat exchanger 2.

[0072] The bottom of the outer casing 1 is normally open to form an installation port, through which the heat exchanger 2, fan 3 and water receiving tray are assembled into the outer casing 1.

[0073] The ceiling-mounted air conditioner also includes a panel assembly 4, which has an air inlet 110 and an air outlet. The panel assembly 4 is located at the bottom of the outer casing 1 and covers the mounting opening. The air inlet 110 is connected to the air inlet channel 51.

[0074] During use, after the fan 3 is running, the outside air enters the air inlet 110 into the air inlet duct 51 under the action of the fan 3. After the air exchanges heat with the heat exchanger 2, the heat-exchanged air is delivered to the air outlet through the air supply duct 52. Finally, the heat-exchanged air is output to the indoor space from the air outlet.

[0075] In some embodiments of this application, in order to facilitate the assembly and disassembly of the grating plate 200 and improve the assembly and disassembly efficiency of the grating plate 200, the connection structure between the panel 100 and the grating plate 200 is structurally improved. Figure 1 This is a structural diagram of a ceiling-mounted air conditioner. Figure 2 This is a cross-sectional view of a ceiling-mounted air conditioner.

[0076] The ceiling-mounted air conditioner includes an outer casing 1, and an installation opening is formed at the bottom of the outer casing 1.

[0077] The ceiling-mounted air conditioner also includes a heat exchanger 2, which is configured to exchange heat with the flowing air. The heat exchanger 2 is disposed in the outer casing 1. An air supply channel 52 is formed between the heat exchanger 2 and the inner wall of the outer casing 1, and an air inlet channel 51 is formed around the heat exchanger 2.

[0078] The ceiling-mounted air conditioner also includes a fan 3, which is located within the air inlet duct 51. The fan 3 rotates to provide power for air circulation.

[0079] The ceiling-mounted air conditioner also includes a panel assembly 4. Figure 3 This is a structural diagram of panel component 4.

[0080] Panel assembly 4 includes panel 100. Figure 10 This is a structural diagram of panel 100 viewed from the bottom side. Figure 16 This is a structural diagram of panel 100 viewed from an obliquely upward angle. Panel 100 is disposed at the bottom of housing 1 and covers the mounting opening. Panel 100 is provided with an air inlet 110 and a first air outlet 120, the first air outlet 120 being arranged outside the air inlet 110. The air inlet 110 communicates with the air inlet channel 51, and the first air outlet 120 communicates with the air supply channel 52.

[0081] A filter screen (not shown) is installed at the air inlet 110. The filter screen is used to filter the incoming air.

[0082] The panel assembly 4 also includes a grille 200. Figure 5 This is a structural diagram of a grating plate 200. Figure 4 This is a structural diagram showing a grating plate 200 suspended below a panel 100. Figure 6 for Figure 5Enlarged view of part A in the middle. Figure 7 for Figure 5 Enlarged view of section B. The grille plate 200 is disposed at the bottom of the panel 100.

[0083] The panel assembly 4 also includes a locking assembly 300. The locking assembly 300 is fixedly disposed on the grille plate 200 and is configured to lock the grille plate 200 to the panel 100. Figure 13 This is a structural diagram of panel 100, grille 200, and latch assembly 300. Figure 14 for Figure 13 Enlarged view of part E in the middle. Figure 15 for Figure 14 A cross-sectional view of the structure shown. Figure 18 This is a structural diagram of the locking assembly 300 and the grille plate 200. Figure 19 for Figure 18 Enlarged view of the middle G section, Figure 20 This is a structural diagram of the locking assembly 300 viewed from an obliquely upward angle. Figure 21 This is a structural diagram of the locking assembly 300 viewed from the bottom side. Figure 22 An exploded view of the locking assembly 300.

[0084] A limiting part 170 is provided on the panel 100. Figure 16 This is a structural diagram of panel 100 viewed from an obliquely upward angle. Figure 17 for Figure 16 Enlarged view of part F in the image. Figure 17 The diagram shows a structural representation of the limiting part 170. The limiting part 170 is a recessed structure, with an opening on the side facing the air inlet 110.

[0085] The locking assembly 300 includes a locking movable part 310, as shown in the reference. Figure 14 , Figure 15 , Figure 18 , Figure 19 as well as Figures 20 to 22 The locking member 310 is slidably disposed on the grille plate 200. The locking member 310 is configured to move toward the panel 100 to engage with the limiting part 170. The locking member 310 is also configured to move away from the panel 100 to disengage from the limiting part 170.

[0086] The latch assembly 300 also includes a locking part configured to lock the latch movable member 310 in a position that engages with the limiting part 170 to connect the panel 100 to the grille plate 200.

[0087] The locking assembly 300 of this application is disposed on the grille plate 200. The locking assembly 300 includes a locking movable member 310 and a locking part. The locking movable member 310 is slidably disposed on the grille plate 200. By manually moving the locking movable member 310, the locking movable member 310 moves horizontally in the direction close to the panel 100. After the locking movable member 310 moves horizontally into position under the manual action, it engages with the limiting part 170. At this time, the locking part locks the locking movable member 310 in the position engaging with the limiting part 170, thereby initially fixing the grille plate 200 to the panel 100. When disassembling the grating plate 200, manually move the locking movable part 310 to release the locking part's limitation on the locking movable part 310. The locking movable part 310 moves horizontally away from the panel 100, and the locking movable part 310 disengages from the limiting part 170, thus releasing the connection between the grating plate 200 and the panel 100.

[0088] The locking assembly 300 of this application achieves automatic locking after the locking movable part 310 is pushed into place through the locking part.

[0089] The locking assembly 300 of this application eliminates the spring. When disassembling the grating plate 200, after the locking movable part 310 disengages from the limiting part 170, it is not necessary to continuously apply the locking movable part 310 by hand. At this time, it is convenient for the user to use both hands to disassemble the snap-fit ​​structure between the grating plate 200 and the panel 100, which facilitates the disassembly of the grating plate 200.

[0090] In some embodiments of this application, reference is made to Figure 13 Two locking assemblies 300 are provided, and the two locking assemblies 300 are arranged opposite to each other on the grating plate 200. The two locking assemblies 300 are used to initially fix the grating plate 200 on the panel 100, preventing the grating plate 200 from falling off.

[0091] In some embodiments of this application, the panel 100 and the grille 200 are detachably snap-fitted together. For example, the panel 100 and the grille 200 are snap-fitted together by a structure such as a snap-fit, eliminating the need for screws 330 and improving the efficiency of assembling and disassembling the grille 200. Furthermore, since the locking assembly 300 eliminates the spring, when disassembling the grille 200, after the locking movable part 310 disengages from the limiting part 170, it is not necessary to continuously apply force to the locking movable part 310 by hand. This allows the user to easily disassemble the snap-fit ​​structure between the grille 200 and the panel 100 using both hands, facilitating the disassembly of the grille 200.

[0092] In some embodiments of this application, reference is made to Figure 9 , Figure 14 and Figure 15 The grating plate 200 is provided with an opening 250. (Refer to...) Figure 21 and Figure 22The locking movable member 310 includes a locking vertical part 312, which is exposed downward through the opening 250.

[0093] The locking movable component 310 also includes a locking horizontal portion 311, which is integral with the locking vertical portion 312. The locking horizontal portion 311 is slidably connected to the grid plate 200 to achieve the sliding setting of the locking movable component 310 on the grid plate 200.

[0094] The latching transverse portion 311 is configured to move above the limiting portion 170 to limit the limiting portion 170 between the latching transverse portion 311 and the grille plate 200, such as Figure 15 As shown.

[0095] The opening 250 extends a distance along the movement direction of the latching member 310, increasing the movement space for the latching member 310. The vertical part 312 of the latch protrudes downward from the opening 250 for the user to hold and operate. After the horizontal part 311 of the latch moves horizontally towards the panel 100 and reaches its position, the locking part locks the horizontal part 311 of the latch in that position. The horizontal part 311 of the latch is located above the limiting part 170, thereby limiting the limiting part 170 between the horizontal part 311 of the latch and the grille plate 200. In this way, the initial fixed installation between the grille plate 200 and the panel 100 is achieved.

[0096] In some embodiments of this application, reference is made to Figure 9 and Figure 15 The grating plate 200 is provided with mounting posts 260. (Refer to...) Figure 21 and Figure 22 The horizontal portion 311 of the latch is provided with an opening 313, which extends along the movement direction of the horizontal portion 311 of the latch, and the mounting post 260 passes through the opening 313.

[0097] When the locking movable part 310 is moved, the mounting post 260 moves along the opening 313, which guides the movement of the locking hole movable part and also enables the locking movable part 310 to slide on the grating plate 200.

[0098] In some embodiments of this application, reference is made to Figure 15 as well as Figures 20 to 22 The locking assembly 300 further includes a locking limiting member 320, which is fixedly installed to the mounting post 260 by a connector (e.g., screw 330). The locking limiting member 320 is configured to restrict the upward displacement of the locking movable member 310, preventing the locking movable member 310 from falling off the mounting post 260.

[0099] The locking limit member 320 covers the opening 250. While limiting the locking movable member 310, the locking limit member 320 also covers the opening 250 to prevent indoor air from flowing into the air conditioner through the opening 250.

[0100] In some embodiments of this application, reference is made to Figures 20 to 22 The locking and limiting member 320 includes a transverse wall 321, which is fixedly installed to the mounting post 260 by a connector (e.g., screw 330). Lateral walls 322 are provided on opposite sides of the transverse wall 321, and a first protrusion 323 is provided on the lateral wall 322. For example, the first protrusion 323 is a raised strip structure extending in a vertical direction.

[0101] A second protrusion 314 is provided on the side wall of the horizontal portion 311 of the latch. The second protrusion 314 abuts against the first protrusion 323 and the second protrusion 314 is located on the side of the first protrusion 323 near the panel 100, so that the latch movable member 310 is locked in the position that cooperates with the limiting portion 170.

[0102] When the latch assembly 300 is in the unlocked position, the second protrusion 314 is located on the side of the first protrusion 323 away from the panel 100. When installing the grille plate 200, the latch movable member 310 is moved towards the panel 100, and the second protrusion 314 passes over the first protrusion 323. The second protrusion 314 is located on the side of the first protrusion 323 closer to the panel 100, and the second protrusion 314 abuts against the first protrusion 323. At this time, the latch movable member 310 is locked in this position by the limiting effect of the first protrusion 323 on the second protrusion 314, that is, the latch movable member 310 is locked in the position that cooperates with the limiting part 170.

[0103] In some embodiments of this application, reference is made to Figure 21 The side wall 322 of the locking limiting member 320 is further provided with a third protrusion 324. The third protrusion 324 is arranged at a distance from the first protrusion 323. The third protrusion 324 is located on the side of the first protrusion 323 away from the panel 100. The third protrusion 324 is configured to limit the movement distance of the locking movable member 310 in the direction away from the panel 100.

[0104] When disassembling the grille panel 200, the locking movable member 310 is moved away from the panel 100. The locking movable member 310 disengages from the limiting part 170, and the second protrusion 314 passes over the first protrusion 323. The second protrusion 314 is located between the first protrusion 323 and the third protrusion 324. The third protrusion 324 blocks the second protrusion 314, which on the one hand limits the movement distance of the locking movable member 310 away from the panel 100, and on the other hand provides an operation prompt to the user, indicating that the locking movable member 310 has disengaged from the limiting part 170.

[0105] In some embodiments of this application, Figure 18 This is a structural diagram of the grille 200 and the locking assembly 300. Figure 19 for Figure 18 In the enlarged view of section G, two spaced-apart limiting plates 270 are provided on the grille plate 200. The lateral wall 322 of the locking limiting member 320 is located inside the limiting plate 270. When the first protrusion 323 and the second protrusion 314 move relative to each other, the limiting plate 270 supports the lateral wall 322 of the locking limiting member 320.

[0106] In some embodiments of this application, the locking portion is a first protrusion 323 provided on the locking limit member 320 and a second protrusion 314 provided on the locking movable member 310. The first protrusion 323 and the second protrusion 314 are convex strip structures extending in the vertical direction. The movement of the locking movable member 310 is restricted by the abutment between the first protrusion 323 and the second protrusion 314, so that the locking movable member 310 is locked in the position that cooperates with the limit member 170.

[0107] In some other embodiments of this application, the grille plate 200 is provided with two spaced-apart limiting plates 270. The locking movable member 310 is located between the two limiting plates 270. The limiting plate 270 is provided with a first protrusion 323, and the locking movable member 310 is provided with a second protrusion 314. The first protrusion 323 and the second protrusion 314 are convex strip structures extending in a vertical direction. The second protrusion 314 abuts against the first protrusion 323 and the second protrusion 314 is located on the side of the first protrusion 323 closer to the panel 100, so that the locking movable member 310 is locked in a position that cooperates with the limiting part 170.

[0108] That is to say, in this embodiment, the locking part is a first protrusion 323 provided on the limiting plate 270 and a second protrusion 314 provided on the locking movable member 310.

[0109] In some embodiments of this application, the latch assembly 300 includes a latching member 310 slidably disposed on the grille plate 200. The latching member 310 is configured to move toward the panel 100 to engage with the limiting portion 170, and the latching member 310 is also configured to move away from the panel 100 to disengage from the limiting portion 170.

[0110] The locking assembly 300 also includes a locking limiting member 320, which is fixedly disposed on the grid plate 200. The locking limiting member 320 is configured to restrict the upward displacement of the locking movable member 310. The locking limiting member 320 is also configured to lock the locking movable member 310 in a position that cooperates with the limiting part 170 to connect the panel 100 to the grid plate 200.

[0111] The locking assembly 300 of this application includes a locking movable member 310 and a locking limiting member 320. The locking movable member 310 is slidably disposed on the grille plate 200. By manually moving the locking movable member 310, the locking movable member 310 moves horizontally in the direction close to the panel 100. After the locking movable member 310 moves horizontally into position close to the panel 100 under the manual action, the locking movable member 310 engages with the limiting part 170 on the panel 100. At this time, the locking limiting member 320 locks the locking movable member 310 in the position engaging with the limiting part 170, thereby initially fixing the grille plate 200 to the panel 100. When disassembling the grating plate 200, manually move the locking movable part 310 to release the locking limit part 320 from limiting the locking movable part 310. The locking movable part 310 moves horizontally away from the panel 100, and the locking movable part 310 disengages from the limiting part 170, thus releasing the connection between the grating plate 200 and the panel 100.

[0112] The locking limit member 320 limits the locking movable member 310 as follows: the locking limit member 320 is provided with a first protrusion 323, and the locking movable member 310 is provided with a second protrusion 314. When the locking assembly 300 is in the unlocked position, the second protrusion 314 is located on the side of the first protrusion 323 away from the panel 100. When installing the grille plate 200, the locking movable member 310 is moved towards the panel 100, and the second protrusion 314 passes over the first protrusion 323. The second protrusion 314 is located on the side of the first protrusion 323 closer to the panel 100, and the second protrusion 314 abuts against the first protrusion 323. At this time, the locking movable member 310 is locked in this position by the limiting effect of the first protrusion 323 on the second protrusion 314, that is, the locking movable member 310 is locked in the position that cooperates with the limiting member 170.

[0113] In some embodiments of this application, reference is made to Figure 10The panel 100 is provided with a first connecting portion 140, which is arranged between the first air outlet 120 and the air inlet 110, and the first connecting portion 140 faces the bottom side of the panel 100. (Refer to...) Figure 16 A second connecting part 150 is provided on the panel 100. The second connecting part 150 is arranged between two adjacent first air outlets 120, and the second connecting part 150 faces the side of the panel 100.

[0114] Panel assembly 4 also includes an air guide plate 500, see reference Figure 3 The air guide plate 500 is located at the first air outlet 120 and is configured to adjust the direction of the airflow flowing out of the first air outlet 120.

[0115] The grille 200 includes a grille body 210 that covers the air inlet 110. The grille body 210 also covers the filter. An air inlet opening 250 is provided on the grille body 210 to allow indoor air to flow into the air conditioner. A third connecting portion 211 is provided on the grille body 210. Figure 7 This is a structural diagram of the third connecting part 211.

[0116] The grating 200 also includes a grating extension 220. (See reference...) Figure 5 The main body of the grille 210 has four corner extensions 220, and the grille panel 200 has a petal-shaped structure. The grille extensions 220 cover the panel 100 area between two adjacent first air outlets 120. A fourth connecting part 221 is provided on the grille extensions 220. Figure 6 This is a structural diagram of the fourth connecting part 221.

[0117] The third connecting part 211 is detachably connected to the first connecting part 140, and the fourth connecting part 221 is detachably connected to the second connecting part 150. This achieves a detachable connection between the grille plate 200 and the panel 100.

[0118] The panel assembly 4 of this application includes a panel 100 and a grille 200. An air inlet 110 is located at the center of the panel 100, and first air outlets 120 are arranged around the air inlet 110, achieving a four-way airflow effect for the air conditioner. The grille 200 has a petal shape and includes a grille body 210 and grille extensions 220. Grille extensions 220 are located at the four corners of the grille body 210. The grille body 210 covers the air inlet 110, and the grille extensions 220 cover the area of ​​the panel 100 between two adjacent first air outlets 120. The petal shape of the grille 200, combined with the air outlet layout on the panel 100, makes the overall panel assembly 4 seamless and improves the product's appearance.

[0119] The connection between the panel 100 and the grille body 210 is achieved through the connection between the first connecting part 140 and the third connecting part 211. The connection between the panel 100 and the grille extension 220 is achieved through the connection between the second connecting part 150 and the fourth connecting part 221. The multi-point connection between the panel 100 and the grille 200 improves the reliability of the connection, and eliminating the screw 330 connection helps improve the efficiency of assembling and disassembling the grille 200. Furthermore, the multi-point connection between the panel 100 and the grille 200 helps prevent airflow between the air inlet and outlet sides.

[0120] In some embodiments of this application, panel assembly 4 includes panel 100. Figure 10 This is a structural diagram of panel 100 viewed from the bottom side. Figure 16 This is a structural diagram of panel 100 viewed from an obliquely upward angle. Panel 100 is disposed at the bottom of housing 1 and covers the mounting opening. Panel 100 is provided with an air inlet 110 and a first air outlet 120, the first air outlet 120 being arranged outside the air inlet 110. The air inlet 110 communicates with the air inlet channel 51, and the first air outlet 120 communicates with the air supply channel 52. Panel 100 is provided with a panel 100 connecting portion.

[0121] A filter screen (not shown) is installed at the air inlet 110. The filter screen is used to filter the incoming air.

[0122] The panel assembly 4 also includes a grille 200. Figure 5 This is a structural diagram of a grille plate 200. The grille plate 200 is disposed at the bottom of the panel 100 and covers the air inlet 110. The grille plate 200 also covers the filter screen. The grille plate 200 is provided with a grille connecting part, and the panel 100 connecting part is detachably connected to the grille connecting part.

[0123] The panel assembly 4 also includes a suspension rope 400. The suspension rope 400 is disposed between the panel 100 and the grille 200, and is configured to suspend the grille 200 below the panel 100. Figure 4 This is a structural diagram of a grating panel 200 suspended below a panel 100 by a suspension rope 400.

[0124] The panel assembly 4 of this application includes a panel 100, a grid panel 200, a locking assembly 300, and a hanging rope 400. A detachable connection between the panel 100 and the grid panel 200 is achieved through a detachable connection between the connecting part of the panel 100 and the connecting part of the grid panel. For example, the detachable connection between the connecting part of the panel 100 and the connecting part of the grid panel is achieved through a snap-fit ​​structure, eliminating the need for screw 330 installation and facilitating the assembly and disassembly of the grid panel 200.

[0125] When the grating plate 200 is installed on the panel 100, the connecting part of the panel 100 is connected to the grating connecting part, and the locking assembly 300 is in a locked state, further limiting the panel 100 and the grating plate 200, improving the connection reliability between the panel 100 and the grating plate 200. At this time, the suspension rope 400 is located between the panel 100 and the grating plate 200 and is not exposed.

[0126] When it is necessary to disassemble the grille 200, first release the locking state of the locking assembly 300, and then move the grille 200 to release the snap between the panel 100 connecting part and the grille connecting part, so that the grille 200 is separated from the panel 100. Then the grille 200 is suspended below the panel 100 by the hanging rope 400 to facilitate maintenance of the air conditioner or replacement of the filter.

[0127] When installing the grating plate 200, the panel 100 and the grating plate 200 are initially fixed by the locking assembly 300, and then the connecting part of the panel 100 is engaged with the connecting part of the grating to achieve reliable fixing of the panel 100 and the grating plate 200. At this time, the hanging rope 400 is stored between the panel 100 and the grating plate 200 and is not exposed.

[0128] In one specific embodiment, the panel 100 connection portion includes a first connection portion 140 and a second connection portion 150. The first connection portion 140 is disposed between the first air outlet 120 and the air inlet 110, and the first connection portion 140 faces the bottom side of the panel 100. The second connection portion 150 is disposed between two adjacent first air outlets 120, and the second connection portion 150 faces the side of the panel 100.

[0129] The grille panel 200 includes a grille body 210 and grille extensions 220. Grille extensions 220 are respectively provided at the four corners of the grille body 210, and the grille panel 200 has an overall petal-shaped structure. The grille body 210 covers the air inlet 110, and the grille extensions 220 cover the panel 100 area between two adjacent first air outlets 120. The grille connecting portion includes a third connecting portion 211 and a fourth connecting portion 221. The third connecting portion 211 is provided on the grille body 210, and the fourth connecting portion 221 is provided on the grille extensions 220.

[0130] The first connecting portion 140 is connected to the third connecting portion 211, thereby connecting the panel 100 and the grille body portion 210. The second connecting portion 150 is connected to the fourth connecting portion 221, thereby connecting the panel 100 and the grille extension portion 220.

[0131] In some embodiments of this application, reference is made to Figure 16 The panel 100 is also provided with a second air outlet 130, which is provided between two adjacent first air outlets 120. The four second air outlets 130 serve as auxiliary air outlets, working in conjunction with the four first air outlets 120 to achieve 360° omnidirectional airflow from the air conditioner.

[0132] In some embodiments of this application, reference is made to Figure 3 The grille extension 220 is configured to cover the second air outlet 130, and an air outlet gap 190 is formed between the grille extension 220 and the panel 100, the air outlet gap 190 being connected to the second air outlet 130.

[0133] The grille extension 220 serves two purposes: firstly, it forms the petal shape of the grille panel 200; secondly, it also covers the second air outlet 130. By utilizing the air outlet gap 190 between the grille extension 220 and the panel 100, the airflow from the second air outlet 130 is converted into horizontal airflow.

[0134] In some embodiments of this application, the first connecting part 140 is detachably snapped into the third connecting part 211, and the second connecting part 150 is detachably snapped into the fourth connecting part 221. This mechanical snap-fit ​​structure achieves a detachable connection between the panel 100 and the grille 200, eliminating the need for screws 330 and improving the efficiency of assembling and disassembling the grille 200.

[0135] In one specific embodiment, reference is made to Figure 10 The panel 100 has a total of eight first connecting parts 140, with two first connecting parts 140 located on either side near the air inlet 110. (See reference...) Figure 5 The main body of the grille 210 is provided with eight third connecting parts 211. In this way, multi-point connection between the panel 100 and the main body of the grille 210 is realized, improving installation reliability and preventing air leakage between the air inlet 110 and the first air outlet 120.

[0136] In one specific embodiment, reference is made to Figure 5The grille 200 has a total of eight fourth connecting parts 221, specifically two fourth connecting parts 221 on any grille extension 220. Correspondingly, the panel 100 has eight second connecting parts 150. In this way, multi-point connection between the panel 100 and the grille extension 220 is achieved, improving installation reliability and preventing air leakage between the air inlet 110 and the second air outlet 130.

[0137] In some embodiments of this application, Figure 11 This is a cross-sectional view showing a connection between the first connecting part 140 and the third connecting part 211. The panel 100 has a sub-mounting port 141. The first connecting part 140 is a connector 142 disposed within the sub-mounting port 141. The connector 142 has a socket 143 facing the bottom side of the panel 100. The connector 142 and the sub-mounting port 141 are installed using a snap-fit ​​method.

[0138] The third connecting part 211 is an insertion part formed on the main body part 210 of the grille. Figure 7 This is a structural diagram of the third connecting part 211. The insertion part is inserted into the socket 143 to realize the connection between the first connecting part 140 and the third connecting part 211.

[0139] Specifically, refer to Figure 11 The lower port diameter of socket 143 is small, while the internal diameter is large. (Refer to...) Figure 7 The third connecting part 211 is a plug structure with a large outer diameter at the top and a small outer diameter at the bottom. The third connecting part 211 is inserted into the socket 143 from bottom to top. During the upward insertion of the third connecting part 211, the connector 142 undergoes elastic deformation, and the upper part of the third connecting part 211 is inserted into the inner cavity of the socket 143 and locked in place.

[0140] In some embodiments of this application, Figure 12 This is a cross-sectional view showing a connection between the second connecting part 150 and the fourth connecting part 221. (Refer to...) Figure 16 The second connecting portion 150 is a hook structure formed on the panel 100, and the second connecting portion 150 faces the side of the panel 100. (See reference...) Figure 6 The fourth connecting part 221 is a hook structure formed on the grille extension 220. In this way, the second connecting part 150 and the fourth connecting part 221 are engaged through the two hook structures.

[0141] The connection point between the second connecting part 150 and the fourth connecting part 221 is located on the side of the air outlet gap 190 between the panel 100 and the grille extension 220, and does not affect the airflow within the air outlet gap 190.

[0142] In some embodiments of this application, reference is made to Figure 4The panel 100 is provided with at least two first rope securing portions 160, which are arranged at intervals on the same side of the panel 100. For example, the first rope securing portion 160 is a perforation provided on the panel 100.

[0143] At least two second rope securing parts 230 are provided on the main body 210 of the grid, and the at least two second rope securing parts 230 are arranged at intervals on the same side of the grid plate 200. Figure 8 This is a structural diagram of the second rope fixing part 230, which is a perforation formed on the grid body part 210.

[0144] The at least two first rope securing parts 160 and the at least two second rope securing parts 230 are correspondingly arranged, and the suspension rope 400 is arranged between any two corresponding first rope securing parts 160 and second rope securing parts 230. One end of the suspension rope 400 is connected to the first rope securing part 160, and the other end of the suspension rope 400 is connected to the second rope securing part 230.

[0145] By providing multiple first rope fixing parts 160 and multiple second rope fixing parts 230, the suspension reliability of the grating plate 200 is improved, and the twisting of the grating plate 200 is prevented. For example, two first rope fixing parts and two second rope fixing parts 230 are provided respectively.

[0146] In some embodiments of this application, the suspension rope 400 is further configured such that when the grid plate 200 is installed on the panel 100, the suspension rope 400 is arranged between the grid plate 200 and the panel 100 and is in a straight state.

[0147] The length of the suspension rope 400 is moderate. When the grille 200 is installed on the panel 100, the suspension rope 400 is straightened in the horizontal direction. The suspension rope 400 will not be pressed down and can avoid the suspension rope 400 from being caught in the fan 3 due to being too long.

[0148] In some embodiments of this application, reference is made to Figure 10 A first guide connection portion 180 is provided on the panel 100. (Refer to...) Figure 5 The main body 210 of the grille is provided with a second guide connecting part 240. The first guide connecting part 180 cooperates with the second guide connecting part 240. For example, the first guide connecting part 180 is an opening 313, and the second guide connecting part 240 is a guide post.

[0149] First guide connecting parts 180 are provided at the four corners of the main body of the grille 210 and on the opposite sides of the air inlet 110, and two second guide connecting parts 240 are also provided accordingly. The insertion and engagement between the first guide connecting parts 180 and the second guide connecting parts 240 plays a role in pre-positioning the installation of the grille plate 200.

[0150] When installing the grating plate 200, bring the grating plate 200 close to the panel 100 from bottom to top. First, insert the second guide connecting part 240 into the first guide connecting part 180 to achieve the initial positioning of the grating plate 200, ensuring a one-to-one correspondence between the first connecting part 140 and the third connecting part 211, and a one-to-one correspondence between the second connecting part 150 and the fourth connecting part 221. Then, lock the locking assembly 300 to initially fix the grating plate 200 onto the panel 100. Next, along the circumference of the grating plate 200, snap the first connecting part 140 into the third connecting part 211 and the second connecting part 150 into the fourth connecting part 221, thus completing the reliable installation of the grating plate 200.

[0151] In some embodiments of this application, reference is made to Figure 3 A guide vane 500 is provided at the first air outlet 120. A first indicator portion 510 is provided on the guide vane 500, and a second indicator portion 280 is provided on the grille body portion 210. The first indicator portion 510 and the second indicator portion 280 are aligned so that the first guide connecting portion 180 and the second guide connecting portion 240 are aligned. For example, the first indicator portion 510 and the second indicator portion 280 can be raised, have a pattern, or be other markings.

[0152] Specifically, when installing the grille plate 200, first align the first indicator part 510 with the second indicator part 280. This ensures that the first guide connecting part 180 and the second guide connecting part 240 are aligned. Then push the grille plate 200 upward to allow the first guide connecting part 180 and the second guide connecting part 240 to be accurately inserted.

[0153] In some embodiments of this application, two grille extensions 220 located on the same side are provided with markings 290, such as Chinese characters, English words, graphics, etc. The markings 290 are arranged opposite to the hanging rope 400. The markings 290 are used to prompt the user to first disconnect the connection between the grille extension 220 on the side where the markings 290 are located and the panel 100 when disassembling the grille panel 200.

[0154] For example, the sign 290 is the English word "Pull", such as Figure 3 As shown.

[0155] In some embodiments of this application, the disassembly process of the grating plate 200 includes:

[0156] Move the latching member 310 toward the middle position of the grille plate 200 until the latching member 310 disengages from the limiting part 170 on the panel 100, that is, the latching member 310 disengages from the panel 100.

[0157] Manually pry open the two grille extensions 220 with the marking part 290, so that the two grille extensions 220 are first separated from the panel 100, and then gradually pry the grille plate 200 downward until the snap-fit ​​structure between the grille plate 200 and the panel 100 is completely released.

[0158] Rotate the grating plate 200 downwards by 90° and suspend the grating plate 200 below the panel 100 using the suspension rope 400.

[0159] In some embodiments of this application, the installation process of the grating plate 200 includes:

[0160] Insert the second guide connection portion 240 on the grille plate 200 into the first guide connection portion 180 on the panel 100. This process can be achieved by using the first indicator portion 510 and the second indicator portion 280. When the first indicator portion 510 and the second indicator portion 280 are aligned, push the grille plate 200 upward to ensure that the second guide connection portion 240 is inserted into the first guide connection portion 180.

[0161] Move the latching member 310 away from the grating plate 200 until the latching member 310 moves above the limiting part 170, and initially fix the grating plate 200 to the panel 100.

[0162] Press the perimeter of the main body 210 and the extension 220 of the grille to engage all the snap-fit ​​structures between the grille plate 200 and the panel 100, thus completing the installation of the grille plate 200.

[0163] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0164] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
