[0066] The air outlet structure 1001 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0067] like Figure 1 and Figure 2 As shown, the air outlet structure 1001 according to an embodiment of the present utility model includes an air outlet frame assembly 100, a rotary bearing 443, an air guide grille 200, and a switch door 300.

[0068] Specifically, if Figure 1 , Figure 2 and Figure 15 As shown, the air outlet structure 1001 is used in the air conditioner 1000, which can be a floor-standing or cabinet-type air conditioner. The air outlet frame assembly 100 has an air outlet duct 201 and an air outlet 202 communicating with the air outlet duct 201. The air outlet 202 extends along the length of the air outlet frame assembly 100. The air conditioner 1000 includes a housing 1005, and the air outlet frame assembly 100 is connected to the housing 1005. The housing 1005 is arranged in a vertically extending cylindrical shape to form the overall appearance of the air conditioner 1000. The housing 1005 is provided with an air inlet 1006 communicating with the air outlet duct 201, so that airflow can enter the air conditioner 1000 from the air inlet 1006 for heat exchange, and then be blown out of the air conditioner 1000 from the air outlet 202 after passing through the air outlet duct 201. The air outlet frame assembly 100 is arranged vertically, that is, the air outlet 202 is along the vertical direction (see attached diagram). Figure 1 The air conditioner 1000 extends in the vertical direction (as shown), thereby expanding the air outlet range of the air conditioner 1000 in the vertical direction and ensuring the air supply effect of the air conditioner 1000.

[0069] like Figure 5 and Figure 6 As shown, an intermediate support part 40 is provided at the air outlet 202. The two ends of the intermediate support part 40 in the length direction are respectively connected to the two walls in the width direction of the air outlet duct 201. The intermediate support part 40 is spaced apart from the two ends in the length direction of the air outlet 202. A connecting hole 401 is provided on the intermediate support part 40, and part of the rotating bearing 443 passes through the connecting hole 401.

[0070] like Figure 16 and Figure 17As shown, the air guide grille 200 is detachably and rotatably mounted at the air outlet 202. The rotation axis of the air guide grille 200 extends along the length of the air outlet 202, thereby allowing the air guide grille 200 to rotate about the rotation axis extending vertically. When airflow flows into the air outlet duct 201 and passes through the air guide grille 200, the air guide grille 200 can rotate in the width direction of the air outlet 202 (e.g., ...). Figure 5 By guiding the airflow in the first direction (as shown), and changing the airflow direction, the air conditioner 1000 can deliver air at different angles along the width of the air outlet 202 to meet the user's air supply needs. It can also increase the air supply angle and range at the air outlet 202, achieving wide-angle air supply from the air outlet structure 1001, thereby improving the air supply effect of the air outlet structure 1001 and enhancing user comfort and experience.

[0071] like Figure 10 and Figure 13 As shown, the air guide grille 200 includes a grille body 41 and a third mounting component 44. The third mounting component 44 is located on one side of the grille body 41 in the thickness direction and spaced apart from both ends of the grille body 41 in the length direction. The third mounting component 44 is rotatably connected to one of the outer peripheral wall and the inner peripheral wall of the rotary bearing 443.

[0072] It is understood that the third mounting component 44 is rotatably connected to the outer peripheral wall of the rotary bearing 443, or the third mounting component 44 is rotatably connected to the inner peripheral wall of the rotary bearing 443. The third mounting component 44 can be located at the middle position in the length direction of the grille body 41. By setting the third mounting component 44 on one side in the thickness direction of the grille body 41, it is convenient to connect the thickness direction side of the middle position in the length direction of the air guide grille 200 to the middle support part 40 of the air outlet frame assembly 100. This can reduce the installation difficulty of the air guide grille 200, while enhancing the connection strength and stability between the air guide grille 200 and the bracket of the air outlet frame assembly 100. It can also ensure the aesthetics of the side of the air guide grille 200 facing away from the third mounting component 44 in the thickness direction. Furthermore, the third mounting component 44 is rotatably connected to one of the outer and inner peripheral walls of the rotary bearing 443, and the third mounting component 44 is rotatably connected to the intermediate support 40, which can ensure the rotatability of the air guide grille 200 relative to the air outlet frame assembly 100, thereby enabling the air guide grille 200 to guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0073] like Figure 16 and Figure 17As shown, the switch door 300 is detachably and rotatably mounted at the air outlet 202. The rotation axis of the switch door 300 extends along the length of the air outlet 202, allowing the switch door 300 to rotate around the vertically extending rotation axis. When airflow flows into the air outlet duct 201 and passes through the switch door 300, the switch door 300 can guide the airflow and change its direction in the width direction of the air outlet 202. This allows the air conditioner 1000 to deliver air at different angles in the width direction of the air outlet 202 to meet the user's air supply needs. It can also increase the air supply angle and range at the air outlet 202, achieving wide-angle air supply from the air outlet structure 1001, thereby improving the air supply effect of the air outlet structure 1001 and enhancing user comfort and experience.

[0074] like Figure 8 and Figure 9 As shown, the door 300 includes a door body 51 and a connecting arm 54. The connecting arm 54 is located on one side of the door body 51 in the thickness direction and is spaced apart from both ends of the door body 51 in the length direction. The connecting arm 54 is rotatably connected to the other of the outer peripheral wall and inner peripheral wall of the rotary bearing 443.

[0075] It is understandable that the connecting arm 54 is rotatably connected to the outer peripheral wall of the rotary bearing 443, or the connecting arm 54 is rotatably connected to the inner peripheral wall of the rotary bearing 443. The connecting arm 54 can be located at the middle position in the length direction of the door body 51. By setting the connecting arm 54 on one side in the thickness direction of the door body 51, it is convenient to connect the thickness direction side of the middle position in the length direction of the switch door 300 to the middle support part 40 of the air outlet frame assembly 100. This can reduce the installation difficulty of the switch door 300, while enhancing the connection strength and stability between the switch door 300 and the bracket of the air outlet frame assembly 100, and also ensuring the aesthetics of the side of the switch door 300 away from the connecting arm 54 in the thickness direction. In addition, the connecting arm 54 is rotatably connected to one of the outer peripheral wall and the inner peripheral wall of the rotary bearing 443, and the connecting arm 54 is rotatably connected to the middle support part 40. This can ensure the rotatability of the switch door 300 relative to the air outlet frame assembly 100, thereby enabling the switch door 300 to guide the airflow and adjust the air supply direction in the width direction of the air outlet 202.

[0076] like Figure 8 and Figure 10As shown, both the grille body 41 and the door body 51 are relatively long parts and are located at the air outlet 202. By setting intermediate support parts 40 at positions spaced apart from both ends of the air outlet 202 in the length direction, the air guide grille 200 and the door 300 can be supported, increasing the support for the air guide grille 200 and the door 300. At the same time, the rotary bearing 443 located in the intermediate support part 40 can realize the coaxial rotation of the air guide grille 200 and the door 300. The door 300 is rotatably connected to the rotary bearing 443 through the connecting arm 54, and the air guide grille 200 can be rotatably connected to the rotary bearing 443 through the third mounting component 44, so as to avoid the rotation of the air guide grille 200 and the rotation of the door 300 interfering with each other.

[0077] According to the air outlet structure 1001 of this utility model embodiment, by providing an intermediate support portion 40 at a position spaced apart from both ends of the air outlet 202 in the length direction of the air outlet frame assembly 100, the air guide grille 200 and the switch door 300 can be supported at the middle position in the length direction of the air outlet frame assembly 100, thereby increasing the support for the air guide grille 200 and the switch door 300; at the same time, the intermediate support portion 40 is provided with a connecting hole 401, and a portion of the rotary bearing 443 passes through the connecting hole 401. The switch door 300 can be rotatably connected to the rotary bearing 443 through the connecting arm 54, and the air guide grille 200 can be rotatably connected to the rotary bearing 443 through the third mounting assembly 44. The rotary bearing 443 provided in the intermediate support portion 40 can realize the coaxial rotation of the air guide grille 200 and the switch door 300, and avoid mutual interference between the rotation of the air guide grille 200 and the rotation of the switch door 300.

[0078] In this embodiment, the rotary bearing 443 separates the connecting arm 54, the third mounting assembly 44, and the intermediate support 40, reducing friction between them. This reduces frictional heat and wear, extending their service life. Furthermore, the rotary bearing 443 improves the stability and reliability of the rotatable connection between the connecting arm 54, the third mounting assembly 44, and the intermediate support 40, ensuring the stability and reliability of the rotation of the air guide grille 200 and the door 300 in the width direction of the air outlet 202.

[0079] In this embodiment, when assembling the air outlet structure 1001, after the rotary bearing 443 is secured to the middle support portion 40 of the air outlet frame assembly 100, the connecting arm 54 of the switch door 300 is first fitted onto the outside of the rotary bearing 443 from top to bottom. Then, the third mounting component 44 of the air guide grille 200 is inserted into the rotary bearing 443 from top to bottom. The same principle applies when disassembling the air outlet structure 1001; first, the air guide grille 200 is removed upwards, and then the switch door 300 is lifted upwards.

[0080] In some embodiments of this utility model, such as Figure 10 and Figure 13 As shown, the third mounting assembly 44 includes a third mounting plate 441 and a mounting ring 442. The third mounting plate 441 is connected to one side of the grille body 41 in the thickness direction. The mounting ring 442 is annular and extends along the length direction of the air outlet 202. One end of the mounting ring 442 is connected to the third mounting plate 441, and the other end of the mounting ring 442 is rotatably inserted into the rotary bearing 443.

[0081] It is understood that the third mounting plate 441 is perpendicular to the grille body 41. One end of the third mounting plate 441 is connected to the grille body 41, and the other end of the third mounting plate 441 extends towards the end opposite to the grille body 41. The mounting ring 442 is connected to one side of the end of the third mounting plate 441 facing the length direction of the grille body 41, that is, the mounting ring 442 is located on the lower side of the third mounting plate 441, and the other end of the annular mounting ring 442 in the axial direction extends towards the end of the length direction of the grille body 41, i.e., downward. The connecting hole 401 also extends in the vertical direction. Thus, the mounting ring 442 can cooperate with the rotating bearing 443 in the connecting hole 401 to form a rotating connection. The structure is simple and easy to implement. This allows the air guide grille 200 to rotate around the axis of the mounting ring 442 at the air outlet 202, thereby enabling the air guide grille 200 to guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0082] In addition, by setting a third mounting plate 441 and a mounting ring 442, it is convenient for operators to directly snap the mounting ring 442 into the rotating bearing 443 at the connection hole 401 from top to bottom, thereby realizing the rotational connection between the middle position of the grille body 41 in the length direction and the air outlet frame assembly 100. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0083] Furthermore, such as Figure 10 and Figure 13 As shown, the third mounting assembly 44 further includes a third guide rib 444, which is located radially outside the mounting ring 442 and is disposed on the side of the third mounting plate 441 on which the mounting ring 442 is located.

[0084] It is understood that the grille body 41 extends vertically, the third mounting plate 441 is perpendicular to the grille body 41, one end of the third guide rib 444 is connected to the lower side of the third mounting plate 441, and the other end extends downward toward the side of the third mounting plate 441 where the mounting ring 442 is located. When the operator fastens the mounting ring 442 into the rotating bearing 443 at the connection hole 401 from top to bottom, the connection position between the third mounting component 44 and the air outlet frame component 100 is in the operator's blind spot. The third guide rib 444 can play a guiding role, guiding the mounting ring 442 to the top of the connection hole 401 so that it can be fastened into the connection hole 401, thereby facilitating blind operation by the operator. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0085] Furthermore, such as Figure 10 and Figure 13 As shown, multiple third guide ribs 444 are spaced apart along the circumferential direction of the mounting ring 442. These multiple third guide ribs 444 are spaced apart along the width direction of the grille body 41. Thus, the end faces of the multiple third guide ribs 444 facing the side of the third mounting plate 441 where the mounting ring 442 is located can simultaneously serve a guiding function. This enhances the stability of the guiding function of the third guide ribs 444 and improves the accuracy of guiding the mounting ring 442 into the connecting hole 401. This, in turn, reduces the installation difficulty of the air guide grille 200 and improves the assembly efficiency of the air outlet structure 1001.

[0086] In some embodiments of this utility model, such as Figure 5 As shown, the intermediate support portion 40 is provided with a grille positioning rib 402, which is located radially outside the connecting hole 401. The grille positioning rib 402 can abut against the third guide rib 444. It can be understood that when the intermediate support portion 40 and the air guide grille 200 rotate relative to each other, the distance between the grille positioning rib 402 and the third guide rib 444 in the circumferential direction of the connecting hole 401 changes. When the grille positioning rib 402 abuts against the third guide rib 444, the third mounting component 44 stops rotating, which can achieve the functions of positioning and limiting, thereby limiting the rotation range of the air guide grille 200 at the air outlet 202, avoiding unnecessary rotation of the air guide grille 200, and thus improving the reliability of the air guide grille 200 in the width direction of the air outlet 202.

[0087] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the connecting arm 54 has a connecting arm body 541 at one end opposite to the door body 51. The connecting arm body 541 is connected to one side of the door body 51 in the thickness direction. A limiting ring 542 is provided on the connecting arm body 541, and the limiting ring 542 is sleeved on the outer peripheral wall of the rotating bearing 443. This allows...

[0088] It is understood that the connecting arm body 541 is connected to one side of the door body 51 in the thickness direction. At least a portion of the connecting arm body 541 extends away from the door body 51. The limiting ring 542 is sleeved on the outer peripheral wall of the rotary bearing 443. The limiting ring 542 is spaced apart from the door body 51, and the axial direction of the limiting ring 542 extends downward towards the end of the length direction of the door body 51. The connecting hole 401 also extends in the vertical direction. Thus, the limiting ring 542 can cooperate with the outer peripheral wall of the rotary bearing 443 to form a rotatable connection. The structure is simple and easy to implement. This allows the door 300 to rotate around the axis of the limiting ring 542 at the air outlet 202, thereby enabling the door 300 to guide the airflow and adjust the air supply direction in the width direction of the air outlet 202.

[0089] In addition, by setting the connecting arm body 541 and the limiting ring 542, the operator can directly fasten the limiting ring 542 from top to bottom into the outer peripheral wall of the rotating bearing 443 at the connecting hole 401, thereby realizing the rotational connection between the middle position of the door body 51 in the length direction and the air outlet frame assembly 100. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0090] Furthermore, such as Figure 8 and Figure 9 As shown, the limiting ring 542 is provided with a reinforcing opening 543. The reinforcing opening 543 passes through the limiting ring 542 along the axial direction of the limiting ring 542. When the connecting arm 54 is an injection molded part, the reinforcing opening 543 can be provided at the injection welding line, which can prevent the limiting ring 542 from short-circuiting and avoid affecting the assembly of the limiting ring 542 and the rotary bearing 443.

[0091] In some embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 7 As shown, the rotary bearing 443 includes a bearing body 4433 and an assembly part 4434. The third mounting assembly 44 and the connecting arm 54 cooperate with the bearing body 4433. At least a portion of the bearing body 4433 is located outside the connecting hole 401. The assembly part 4434 is located at one end of the bearing body 4433 in the axial direction and is inserted into and connected to the connecting hole 401. Thus, the bearing body 4433 is located at the upper end of the assembly part 4434. The bearing body 4433 and the assembly part 4434 extend along the length direction of the air outlet 202, i.e., the vertical direction. The assembly part 4434 and part of the bearing body 4433 pass through the connecting hole 401 in the vertical direction. At least a portion of the bearing body 4433 is engaged at the upper end of the connecting hole 401, thereby limiting the rotary bearing 443 and preventing the rotary bearing 443 from falling out of the connecting hole 401 during assembly.

[0092] Furthermore, after the air guide grille 200 and the switch door 300 are assembled with the air outlet frame assembly 100, the third mounting assembly 44 can be located above the limiting ring 542 along the length direction of the air outlet 202. The limiting ring 542 is shorter in length to facilitate the assembly of the switch door 300, while the mounting ring 442 is longer in length so that after assembly, the third mounting assembly 44 can restrict the limiting ring 542 from coming off the upper part of the rotary bearing 443.

[0093] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, the assembly part 4434 includes an assembly part body 4435 and a plurality of hooks 4436 spaced apart along the circumferential direction of the assembly part body 4435. The bearing body 4433, the assembly part body 4435, and the hooks 4436 are arranged sequentially along the axial direction of the connecting hole 401. It can be understood that the plurality of hooks 4436 are spaced apart in the circumferential direction of the assembly part body 4435. When the rotating bearing 443 is inserted into the hole, the hooks 4436 can deform inward, which facilitates the insertion of the assembly part 4434 into the connecting hole 401, and can reduce the weight of the rotating bearing 443 and the weight of the air outlet structure 1001, thereby avoiding excessive driving pressure when the air outlet structure 1001 is in operation.

[0094] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, a limiting protrusion 4437 is provided on the end face of the hook 4436 away from the assembly body 4435. The end face of the limiting protrusion 4437 near the assembly body 4435 can abut against the axial end face of the intermediate support part 40, which has a connecting hole 401. Thus, the limiting protrusion 4437 is provided at the lower end of the assembly part 4434, and can limit the rotation bearing 443, preventing the rotation bearing 443 from displacing upward from the connecting hole 401 and falling out when subjected to external impact, thereby ensuring the reliability of the position of the rotation bearing 443.

[0095] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, a limiting protrusion 4438 is provided at the end of the outer peripheral wall of the bearing body 4433 away from the hook 4436. The axial end face of the limiting protrusion 4438 near the hook 4436 abuts against the axial end face of the intermediate support part 40 where the connecting hole 401 is provided. Thus, the limiting protrusion 4438 is provided at the upper end of the bearing body 4433 and is engaged at the upper end of the connecting hole 401, thereby limiting the rotation bearing 443 and preventing the rotation bearing 443 from falling out of the connecting hole 401 during assembly.

[0096] In some embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 7 As shown, the inner diameter of the connecting hole 401 gradually decreases along the direction from the bearing body 4433 to the limiting protrusion 4437. The connecting hole 401 can provide guidance for the process of inserting the rotary bearing 443 into the connecting hole 401, allowing the hook 4436 to deform gradually, avoiding breakage of the hook 4436, and increasing the reliability of the assembly of the rotary bearing 443.

[0097] In some embodiments of this utility model, such as Figure 3 As shown, the inner peripheral wall of the rotary bearing 443 is provided with an inner oil groove 4431. The inner oil groove 4431 extends along the axial direction of the rotary bearing 443. Multiple inner oil grooves 4431 are spaced apart along the circumferential direction of the rotary bearing 443. The inner oil groove 4431 contains lubricating oil, which can reduce the friction between the mounting ring 442 and the inner peripheral wall of the rotary bearing 443 when the air guide grille 200 rotates, thereby improving the smoothness of the rotation of the air guide grille 200 and thus improving the stability of the air guide grille 200 in the width direction of the air outlet 202.

[0098] Furthermore, the extension direction of the inner oil groove 4431 is the same as the axial direction of the rotary bearing 443, which helps to reduce the machining difficulty of the inner oil groove 4431, thereby effectively reducing the production and processing costs of the rotary bearing 443 and the inner oil groove 4431 and improving production efficiency. On the other hand, the inner oil groove 4431 extends along the axial direction of the rotary bearing 443, which can ensure that the lubricating oil is evenly distributed in the axial direction of the inner peripheral wall of the rotary bearing 443, so as to ensure the lubrication effect of the lubricating oil, thereby further improving the smoothness and stability of the mounting ring 442 rotating in the rotary bearing 443.

[0099] Furthermore, by setting multiple inner oil grooves 4431, the lubricating oil can be distributed in multiple locations along the circumferential direction of the outer peripheral wall of the mounting ring 442, thereby ensuring the lubrication effect of the lubricating oil. When the air guide grille 200 rotates, the friction between the mounting ring 442 and the inner peripheral wall of the rotary bearing 443 can be effectively reduced, thereby improving the smoothness and stability of the mounting ring 442 rotating within the rotary bearing 443, and improving the stability of the air guide grille 200 in the width direction of the air outlet 202.

[0100] In some embodiments of this utility model, such as Figure 3As shown, the outer peripheral wall of the rotary bearing 443 is provided with an outer oil groove 4432, which extends along the axial direction of the rotary bearing 443. Multiple outer oil grooves 4432 are spaced apart along the circumferential direction of the rotary bearing 443. The outer oil groove 4432 contains lubricating oil, which can reduce the friction between the intermediate support part 40 and the outer peripheral wall of the rotary bearing 443 when the door 300 rotates, thereby improving the smoothness of the door 300's rotation and enabling wide-angle air delivery of the air outlet structure 1001.

[0101] Furthermore, the extension direction of the outer oil groove 4432 is the same as the axial direction of the rotary bearing 443, which helps to reduce the machining difficulty of the outer oil groove 4432, thereby effectively reducing the production and processing costs of the rotary bearing 443 and the outer oil groove 4432 and improving production efficiency. On the other hand, the outer oil groove 4432 extends along the axial direction of the rotary bearing 443, which can ensure that the lubricating oil is evenly distributed in the axial direction of the outer peripheral wall of the rotary bearing 443, so as to ensure the lubrication effect of the lubricating oil, thereby further improving the smoothness and stability of the rotary bearing 443 rotating in the intermediate support part 40.

[0102] In addition, by setting multiple outer oil grooves 4432, the lubricating oil can be distributed in multiple places in the circumferential direction of the inner peripheral wall of the intermediate support part 40, thereby ensuring the lubrication effect of the lubricating oil. When the door 300 rotates, the friction between the intermediate support part 40 and the outer peripheral wall of the rotary bearing 443 can be effectively reduced, thereby improving the smoothness and stability of the rotary bearing 443 rotating in the intermediate support part 40, and realizing the wide-angle air supply of the air outlet structure 1001.

[0103] In some embodiments of this utility model, multiple intermediate support portions 40 are spaced apart along the length of the air outlet 202, and multiple third mounting components 44 and connecting arms 54 correspond one-to-one with the multiple intermediate support portions 40. The third mounting components 44 and connecting arms 54 can be supported at multiple points along the length of the air outlet 202, increasing support for the air guide grille 200 and the door 300, and preventing deformation of the air guide grille 200 and the door 300 during rotation.

[0104] In some embodiments of this utility model, the rotary bearing 443 is a POM (Polyoxymethylene) component. POM has high hardness, high strength, high rigidity and good elastic modulus, which makes the rotary bearing 443 perform well under heavy load and impact and maintain stable performance.

[0105] The air outlet frame assembly 100 is vertically arranged, and the air outlet 202 and the grille body 41 extend in the vertical direction. The first end 411 can be the upper end of the grille body 41, and the second end 412 can be the lower end of the grille body 41.

[0106] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the air guide grille 200 also includes a first mounting component 42, which is located on one side of the first end 411 in the thickness direction and rotatably connected to the air outlet frame assembly 100. By providing the first mounting component 42 on one side of the grille body 41 in the thickness direction, it is easier to connect one side of the air guide grille 200 in the thickness direction to the air outlet frame assembly 100, which reduces the installation difficulty of the air guide grille 200 and also ensures the aesthetics of the side of the air guide grille 200 away from the first mounting component 42 in the thickness direction. At the same time, the rotatable connection between the first mounting component 42 and the air outlet frame assembly 100 ensures the rotatability of the air guide grille 200 relative to the air outlet frame assembly 100, thereby enabling the air guide grille 200 to guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0107] In some embodiments of this utility model, such as Figure 10 , Figure 11 , Figure 18 and Figure 19 As shown, the air outlet frame assembly 100 has a first rotating hole 7124 at one end near the first end 411. The first mounting assembly 42 includes a first mounting plate 421 and an inner ring portion 422. The first mounting plate 421 is connected to the grille body 41. The inner ring portion 422 is annular and one end in the axial direction is connected to the side of the first mounting plate 421 facing the second end 412. The inner ring portion 422 is rotatably disposed in the first rotating hole 7124.

[0108] It is understood that the first mounting plate 421 is perpendicular to the grille body 41, one end of the first mounting plate 421 is connected to the grille body 41, and the other end of the first mounting plate 421 extends toward the end opposite to the grille body 41. The inner ring portion 422 is connected to the side of the first mounting plate 421 facing the second end 412, that is, the inner ring portion 422 is located on the lower side of the first mounting plate 421, and the other end of the annular inner ring portion 422 extends toward the second end 412, i.e., downwards. The first rotating hole 7124 also extends in the vertical direction. Thus, the inner ring portion 422 can cooperate with the first rotating hole 7124 to form a rotating connection. The structure is simple and easy to implement. This allows the air guide grille 200 to rotate around the axis of the inner ring portion 422 at the air outlet 202, thereby enabling the air guide grille 200 to guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0109] In addition, by setting the first mounting plate 421 and the inner ring 422, it is convenient for the operator to directly snap the inner ring 422 into the first rotating hole 7124 from top to bottom, thereby realizing the rotational connection between the first end 411 of the grille body 41 and the air outlet frame assembly 100. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0110] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 6-Figure 8 As shown, the air outlet frame assembly 100 has an annular boss 7123 at one end near the first end 411. The first rotating hole 7124 passes through the annular boss 7123. The first mounting assembly 42 also includes an outer ring portion 423. The outer ring portion 423 is annular and one end in the axial direction is connected to the side of the first mounting plate 421 facing the second end 412. The outer ring portion 423 is sleeved outside the inner ring portion 422 and spaced apart from the inner ring portion 422. The annular boss 7123 is located between the inner ring portion 422 and the outer ring portion 423.

[0111] It is understandable that the outer ring portion 423 is connected to the side of the first mounting plate 421 facing the second end 412, that is, the outer ring portion 423 is located on the lower side of the first mounting plate 421 and is sleeved outside the inner ring portion 422. The outer ring portion 423, which is spaced apart from the inner ring portion 422, can play a limiting role. When the operator fastens the inner ring portion 422 into the first rotating hole 7124 from top to bottom, the outer ring portion 423 can limit the annular boss 7123 between the outer ring portion 423 and the inner ring portion 422, thereby ensuring the connection stability of the annular boss 7123, and thus improving the stability of the air guide grille 200 in the width direction of the air outlet 202.

[0112] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 6-Figure 8 As shown, the inner circumferential wall of the outer ring portion 423 is provided with a rotating rib 4231, and the outer circumferential wall of the annular boss 7123 is provided with a rotating positioning rib 7125. Along the circumferential direction of the outer ring portion 423, the rotating rib 4231 can abut against the rotating positioning rib 7125. It can be understood that when the inner ring portion 422 and the annular boss 7123 rotate, the distance between the rotating rib 4231 and the rotating positioning rib 7125 along the circumferential direction of the inner ring portion 422 changes. When the rotating rib 4231 abuts against the rotating positioning rib 7125, the inner ring portion 422 stops rotating, thus achieving positioning and limiting functions. This limits the rotation range of the air guide grille 200 at the air outlet 202, preventing unnecessary rotation of the air guide grille 200 and improving the reliability of the air guide grille 200's rotational airflow guidance in the width direction of the air outlet 202.

[0113] Specifically, if Figure 19 As shown in the example, the annular boss 7123 has two rotating positioning ribs 7125 on its outer peripheral wall. When the annular boss 7123 is located between the outer ring portion 423 and the inner ring portion 422, the rotating rib 4231 is placed between the two rotating positioning ribs 7125 along the circumferential direction of the inner ring portion 422. Thus, when the inner ring portion 422 rotates, the rotating rib 4231 rotates between the two rotating positioning ribs 7125 along the circumferential direction of the inner ring portion 422. When the rotating rib 4231 abuts against one of the rotating positioning ribs 7125, the inner ring portion 422 stops rotating. The two rotating positioning ribs 7125 can achieve positioning and limiting of the rotation of the annular boss 7123 in two directions, thereby limiting the rotation range of the air guide grille 200 at the air outlet 202 in two directions.

[0114] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the first mounting assembly 42 also includes a first guide rib 424, which is located radially outside the outer ring portion 423 and is provided on the side of the first mounting plate 421 facing the second end 412. In the direction away from the axis of the inner ring portion 422, the end face of the first guide rib 424 facing the second end 412 is inclined toward the second end 412.

[0115] It is understood that the grille body 41 extends in the vertical direction, the first mounting plate 421 is set perpendicular to the grille body 41, one end of the first guide rib 424 is connected to the lower side of the first mounting plate 421, and the other end extends downward toward the second end 412. At the same time, in the direction away from the axis of the inner ring 422, the lower end face of the first guide rib 424 is inclined toward the second end 412. When the operator inserts the inner ring 422 into the first rotating hole 7124 from top to bottom, the connection position between the first mounting assembly 42 and the air outlet frame assembly 100 is in the operator's blind spot. The lower end face of the inclined first guide rib 424 can play a guiding role, which can guide the inner ring 422 to the top of the first rotating hole 7124 so that it can be inserted into the first rotating hole 7124. This makes it easy for the operator to operate blindly, and the installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0116] In some embodiments of this utility model, such as Figure 10 and Figure 11As shown, multiple first guide ribs 424 are spaced apart along the circumferential direction of the outer ring portion 423. These multiple first guide ribs 424 are spaced apart along the width direction of the grille body 41, so that the end faces of the multiple first guide ribs 424 facing the second end 412 can simultaneously play a guiding role. This enhances the stability of the guiding function of the first guide ribs 424 and also improves the accuracy of guiding the inner ring portion 422 into the first rotating hole 7124, thereby reducing the installation difficulty of the air guide grille 200 and improving the assembly efficiency of the air outlet structure 1001.

[0117] In some embodiments of this utility model, such as Figure 10 , Figure 12 and Figure 20 As shown, the air guide grille 200 also includes a second mounting component 43, which is located on one side of the second end 412 in the thickness direction and connected to the air outlet frame assembly 100. By providing the second mounting component 43 on one side of the grille body 41 in the thickness direction, it is easier to connect the second end 412 of the air guide grille 200 in the thickness direction to the air outlet frame assembly 100, which reduces the installation difficulty of the air guide grille 200 and also ensures the aesthetics of the side of the air guide grille 200 facing away from the second mounting component 43 in the thickness direction.

[0118] In some embodiments of this utility model, such as Figure 10 , Figure 12 and Figure 20 As shown, the air outlet frame assembly 100 includes an air outlet frame 20 and a rotating member 30. The rotating member 30 is rotatably mounted on the air outlet frame 20, and the second mounting assembly 43 is fixedly connected to the rotating member 30. By providing the rotating member 30 on the air outlet frame 20, it is easy to install the grille body 41 onto the air outlet frame 20 via the second mounting assembly 43 and the rotating member 30. The structure is simple and easy to implement, which can reduce the installation difficulty of the air guide grille 200. At the same time, the rotating member 30 is rotatably mounted on the air outlet frame 20, so that the grille body 41 and the air outlet frame 20 can be rotatably connected, allowing the air guide grille 200 to rotate around the axis of the rotating member 30 at the air outlet 202. This allows the air guide grille 200 to guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0119] In some embodiments of this utility model, such as Figure 10 , Figure 12 and Figure 20As shown, the rotating member 30 is provided with a connecting plate 301 extending toward the first end 411. The second mounting assembly 43 includes a second mounting plate 431 and a mating rib 432. The second mounting plate 431 is connected to the grid body 41. The mating rib 432 is connected to the side of the second mounting plate 431 away from the first end 411. The mating rib 432 defines a mating groove 4321. The end of the connecting plate 301 facing the first end 411 is inserted into the mating groove 4321.

[0120] It is understood that the air outlet 202 and the grille body 41 extend in the vertical direction, the second mounting plate 431 is set perpendicular to the grille body 41, one end of the second mounting plate 431 is connected to the grille body 41, and the other end of the second mounting plate 431 extends toward the end away from the grille body 41. The mating rib 432 is set on the lower side of the second mounting plate 431 and extends toward the second end 412, i.e. downward. The mating rib 432 can be formed into a ring or a semi-ring, thereby defining the mating groove 4321.

[0121] like Figure 13 and Figure 14 As shown, the connecting plate 301 extends towards the first end 411, i.e., upward, to facilitate the operator to install the air guide grille 200 from top to bottom, so that the connecting plate 301 can extend into the mating groove 4321. At the same time, the mating rib 432 can play a positioning and limiting role, limiting the connecting plate 301 in the mating groove 4321, which facilitates the connection between the second mounting component 43 and the connecting plate 301, and also helps to improve the stability of the connection.

[0122] The air conditioner 1000 according to an embodiment of the present invention includes the air outlet structure 1001 described above.

[0123] According to the embodiment of the present utility model, the air conditioner 1000 has an intermediate support portion 40 provided at a position spaced apart from both ends of the air outlet 202 along its length. This intermediate support portion 40 can support the air guide grille 200 and the switch door 300 at the middle position along the length of the air outlet frame assembly 100, thereby increasing the support for the air guide grille 200 and the switch door 300. At the same time, the intermediate support portion 40 is provided with a connecting hole 401, and a portion of the rotary bearing 443 passes through the connecting hole 401. The switch door 300 can be rotatably connected to the rotary bearing 443 through the connecting arm 54, and the air guide grille 200 can be rotatably connected to the rotary bearing 443 through the third mounting assembly 44. The rotary bearing 443 provided in the intermediate support portion 40 can realize the coaxial rotation of the air guide grille 200 and the switch door 300, and avoid mutual interference between the rotation of the air guide grille 200 and the rotation of the switch door 300.

[0124] In some embodiments of this utility model, such as Figures 15-17As shown, the grille body 41 is arc-shaped, the door body 51 is arc-shaped, and the air conditioner 1000 also includes a top cover 1002. The top cover 1002 is located on one side of the air outlet frame assembly 100 along its length. The outer edge of the top cover 1002 opposite to the air outlet 202 is arc-shaped, matching the grille body 41 and the door body 51. The air outlet 202 and the air outlet frame assembly 100 extend in the vertical direction shown in the figure. The top cover 1002 is located at the upper end of the air outlet frame assembly 100 but does not block the upper end of the air outlet 202. That is, the upper end of the air outlet 202 corresponding to the grille body 41 and the door body 51 is open, which makes it convenient for operators to lift the grille body 41 and the door body 51 to a certain height to complete the installation and removal of the air guide grille 200.

[0125] The outer edge of the top cover 1002 opposite to the air outlet 202 is an arc shape that matches the grille body 41 and the door body 51. As a result, when the grille body 41 and the door body 51 are lifted to a certain height, the grille body 41 and the door body 51 can avoid each other from the top cover 1002, thereby preventing the grille body 41 and the door body 51 from colliding with the top cover 1002. This allows the operator to smoothly complete the installation and removal of the air guide grille 200 and the door 300.

[0126] The air outlet structure 1001 and other components and operations of the air conditioner 1000 having the same according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0127] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the illustrative use of the above terms does not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0128] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
