Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[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 , Figure 2 and Figure 15 As shown, the air outlet structure 1001 according to an embodiment of the present invention includes an air outlet frame 20, an air guide grille 200, and a drive component 500.

[0068] Specifically, such as Figure 1 , Figure 2 , Figures 13-15As 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 20 has an air outlet duct 201 and an air outlet 202 connected to the air outlet duct 201. The air outlet 202 extends along the length of the air outlet frame 20 (e.g., along the length of the air outlet frame 20). Figure 1 The air conditioner 1000 extends vertically (as shown in the vertical direction). The air conditioner 1000 includes a housing 1005, with an air outlet frame 20 connected to the housing 1005. The housing 1005 is a vertically extending cylindrical shape, forming the overall appearance of the air conditioner 1000. The housing 1005 has an air inlet 1006 communicating with the air outlet duct 201, allowing airflow to enter the air conditioner 1000 through the air inlet 1006 for heat exchange, and then exit the air conditioner 1000 through the air outlet 202 after passing through the air outlet duct 201. The air outlet frame 20 is vertically arranged, meaning the air outlet 202 extends vertically (see attached diagram). Figure 1 and attached Figure 13 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] Among them, such as Figure 4 As shown, the air guide grille 200 includes a grille body 41, which is detachably and rotatably disposed at the air outlet 202. The rotation axis of the grille body 41 extends along the length of the air outlet 202. Thus, the grille body 41 can 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 guide the airflow and change its direction in the width direction of the air outlet 202, thereby enabling the air conditioner 1000 to achieve the desired airflow direction. Figure 14 The air is supplied at different angles in the left and right directions to meet the user's air supply needs. The air supply angle and air supply range at the air outlet 202 can also be increased to achieve wide-angle air supply of the air outlet structure 1001, thereby improving the air supply effect of the air outlet structure 1001 and enhancing the user's comfort and experience.

[0070] Furthermore, the air guide grille 200 is detachably connected to the air outlet frame 20, which enhances the flexibility and convenience of installing and removing the air guide grille 200. This facilitates future inspection, repair, or replacement of the air guide grille 200, thereby reducing the maintenance difficulty and cost of the air guide grille 200. Simultaneously, the detachable air guide grille 200 allows users to remove it for cleaning, and also facilitates cleaning the side walls of the air outlet duct 201. This improves both the ease of cleaning the air outlet structure 1001 and its cleaning effect, thus contributing to the cleanliness of the air supplied by the air conditioner 1000.

[0071] like Figure 4As shown, the two ends of the grille body 41 along the length of the air outlet 202 are a first end 411 and a second end 412, respectively, both of which are rotatably connected to the air outlet frame 20. This allows the grille body 41 to rotate around a rotation axis extending along the length of the air outlet 202, thereby enabling the air guide grille 200 to guide airflow and adjust the air delivery direction in the width direction of the air outlet 202. The fact that both ends of the grille body 41 are connected to the air outlet frame 20 ensures the stability of the connection between the grille body 41 and the air outlet frame 20, and also helps to improve the rotational smoothness of the air guide grille 200.

[0072] The air outlet frame 20 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.

[0073] like Figure 4 and Figure 5 As shown, the first mounting component 42 is located on the side of the air guide grille 200 near the first end 411 in the thickness direction and is rotatably connected to the air outlet frame 20. By setting the first mounting component 42 on one side of the grille body 41 in the thickness direction, it is convenient to connect the side of the air guide grille 200 in the thickness direction to the air outlet frame 20, which can reduce the installation difficulty of the air guide grille 200 and also ensure the aesthetics of the side of the air guide grille 200 away from the first mounting component 42 in the thickness direction. Along the length direction of the air outlet 202, the driving component 500 is located at one end of the grille body 41 near the first end 411. The driving component 500 includes a driving bracket 71, and the air guide grille 200 is rotatably connected to the driving bracket 71 for adjusting the air delivery direction in the width direction of the air outlet 202. By rotatably connecting the air guide grille 200 to the drive bracket 71, the air guide grille 200 can be connected to the air outlet frame 20. While supporting and fixing the air guide grille 200, the air guide grille 200 is allowed to rotate around its rotation axis. This ensures the structural stability of the air outlet structure 1001 and enables the air outlet structure 1001 to deliver air at different angles in the width direction of the air outlet 202.

[0074] like Figure 2 and Figure 3 As shown, the drive bracket 71 has a first rotating hole 7124 on the side near the first end 411, and at least a portion of the first mounting component 42 rotatably extends into the first rotating hole 7124. It is understood that at least a portion of the first mounting component 42 can cooperate with the first rotating hole 7124 to form a rotating connection, resulting in a simple and easily implemented structure. This allows the air guide grille 200 to rotate around the axis of the first rotating hole 7124 at the air outlet 202, thereby enabling the air guide grille 200 to guide airflow and adjust the air delivery direction in the width direction of the air outlet 202.

[0075] According to the air outlet structure 1001 of the present invention, by providing an air outlet duct 201 and an air outlet 202 communicating with the air outlet duct 201 on the air outlet frame 20, and making the grille body 41 detachably and rotatably disposed at the air outlet 202, wherein the rotation axis of the grille body 41 extends along the length direction of the air outlet 202, the air guide grille 200 can guide the airflow and adjust the air delivery direction in the width direction of the air outlet 202 to meet the user's air delivery needs. At the same time, the air guide grille 200 is rotatably connected to the drive bracket 71. The drive bracket 71 has a first rotation hole 7124 on the side near the first end 411. At least a portion of the first mounting component 42 is rotatably extended into the first rotation hole 7124. At least a portion of the first mounting component 42 can cooperate with the first rotation hole 7124 to form a rotational connection. The structure is simple and easy to implement. This allows the air guide grille 200 to rotate around the axis of the first rotating hole 7124 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.

[0076] In some embodiments of the present invention, such as Figures 3-5 As shown, the air outlet frame 20 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.

[0077] 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.

[0078] 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 20. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0079] In some embodiments of the present invention, such as Figure 5 As shown, a rotating shaft oil groove 4221 is provided on the outer peripheral wall of the inner ring portion 422. The rotating shaft oil groove 4221 extends along the axial direction of the inner ring portion 422 and contains lubricating oil. When the air guide grille 200 rotates, it can reduce the friction between the inner ring portion 422 and the side wall of the first rotating hole 7124, thereby improving the smoothness of the rotation of the air guide grille 200 and further improving the stability of the air guide grille 200 in the width direction of the air outlet 202.

[0080] Furthermore, the fact that the rotating shaft oil groove 4221 and the inner ring portion 422 extend in the same direction helps reduce the machining difficulty of the rotating shaft oil groove 4221, thereby effectively reducing the production and machining costs of the inner ring portion 422 and the rotating shaft oil groove 4221 and improving production efficiency. On the other hand, the fact that the rotating shaft oil groove 4221 extends along the axial direction of the inner ring portion 422 ensures that the lubricating oil is evenly distributed in the axial direction of the outer peripheral wall of the inner ring portion 422, so as to ensure the lubrication effect of the lubricating oil, thereby further improving the smoothness and stability of the rotation of the inner ring portion 422 within the first rotating hole 7124.

[0081] In some embodiments of the present invention, such as Figure 5 As shown, the outer peripheral wall of the inner ring portion 422 is provided with a rotating shaft oil groove 4221, and multiple rotating shaft oil grooves 4221 are spaced apart along the circumferential direction of the inner ring portion 422. The rotating shaft oil grooves 4221 contain lubricating oil. By providing multiple rotating shaft oil grooves 4221, the lubricating oil can be distributed at multiple points along the circumferential direction of the outer peripheral wall of the inner ring portion 422, thereby ensuring the lubrication effect of the lubricating oil. When the air guide grille 200 rotates, it effectively reduces the friction between the inner ring portion 422 and the side wall of the first rotating hole 7124, thereby improving the smoothness and stability of the rotation of the inner ring portion 422 within the first rotating hole 7124, and improving the stability of the air guide grille 200 in the width direction of the air outlet 202.

[0082] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the drive bracket 71 has an annular boss 7123 at one end near the first end 411, and 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.

[0083] It is understood 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 between the first mounting plate 421 and the annular boss 7123, and thus improving the stability of the air guide grille 200 rotating and guiding the air in the width direction of the air outlet 202.

[0084] In some embodiments of the present invention, such as Figures 2-5 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.

[0085] Specifically, such as Figure 5As 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.

[0086] In some embodiments of the present invention, such as Figure 5 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.

[0087] 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 component 42 and the air outlet frame 20 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.

[0088] In some embodiments of the present invention, such as Figure 5 As 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.

[0089] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the first mounting component 42 is spaced apart from the end face of the first end 411 of the grille body 41. In a specific embodiment, the grille body 41 extends vertically. When the air guide grille 200 is assembled to the air outlet 202, the height of the first mounting component 42 is lower than the height of the end face of the first end 411. This effectively increases the space for the grille body 41 to move vertically at the air outlet 202, making it easier to slightly raise the first mounting component 42 and install it onto the air outlet frame 20 from top to bottom. It also facilitates the removal of the air guide grille 200 and prevents the first mounting component 42 from colliding with components such as the top cover 1002 above the air conditioner 1000 during installation or removal.

[0090] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, a first reinforcing rib 425 is provided between the grille body 41 and the first mounting assembly 42. The first reinforcing rib 425 is located on the side of the first mounting assembly 42 away from the second end 412. The first reinforcing rib 425 extends along the circumferential direction of the first mounting assembly 42, and its two ends in the length direction are respectively connected to the two ends in the width direction of the grille body 41. One end of the first reinforcing rib 425 in the width direction is connected to the first mounting assembly 42, and the other end in the width direction extends in a direction away from the second end 412. This strengthens the connection between the first mounting assembly 42 and the grille body 41, thereby enhancing the structural stability of the air guide grille 200.

[0091] The end face of the first reinforcing rib 425 facing away from the second end 412 is spaced apart from the end face of the first end 411. When the air guide grille 200 is assembled to the air outlet 202 extending in the vertical direction, the height of the end face of the first reinforcing rib 425 facing away from the second end 412 is lower than the height of the end face of the first end 411. This can effectively increase the space for the first mounting component 42 to move up and down at the air outlet 202, making it easier to slightly raise the first mounting component 42 and install it onto the air outlet frame 20 from top to bottom. At the same time, it is also easy to disassemble the air guide grille 200, which can prevent the first reinforcing rib 425 from colliding with the top cover 1002 and other components above the air conditioner 1000 during installation or disassembly.

[0092] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the air outlet structure 1001 also includes a door 300, which is rotatably mounted at the air outlet 202. The drive component 500 also includes a door drive 72, which is connected to a drive bracket 71 and is used to drive the door 300 to rotate to open or close the air outlet 202. The drive bracket 71 is connected to the air outlet frame 20 and the door drive 72 respectively. The door 300 can be connected to the output shaft of the door drive 72, so that the door 300 is connected to the air outlet frame 20, allowing the door 300 to rotate around its rotation axis while supporting and fixing the door in place. When the air conditioner 1000 is supplying air, the door 300 can rotate to the position where the air outlet 202 is open to ensure airflow and reduce air volume loss; when the air conditioner 1000 is turned off, the door 300 can rotate to the position where the air outlet 202 is closed, which can play a dust prevention role to ensure the cleanliness of the inside of the air conditioner 1000. It should be noted that when the door 300 closes the air outlet 202, the air guide grille 200 is located inside the door 300, which can ensure the aesthetic appearance of the air conditioner 1000.

[0093] In some embodiments of the present invention, such as Figure 2 As shown, at least a portion of the door opening / closing drive member 72 extends radially inward into the inner ring portion 422. The fitting clearance between the door opening / closing drive member 72 and the inner peripheral wall of the inner ring portion 422 is L and satisfies: L>1mm. It can be understood that the fitting clearance between the door opening / closing drive member 72 and the inner peripheral wall of the inner ring portion 422 is greater than 1mm, ensuring a certain distance between the door opening / closing drive member 72 and the inner ring portion 422, and a certain distance between the door opening / closing drive member 72 and the air guide grille 200. This prevents the door opening / closing drive member 72 or the air guide grille 200 from vibrating due to friction, thereby increasing the rotational stability of the air guide grille 200 and the door opening / closing 300.

[0094] In some embodiments of the present invention, such as Figure 2 As shown, along the axial direction of the first rotating hole 7124, the end of the first rotating hole 7124 away from the first mounting plate 421 is spaced apart from the inner ring portion 422. For example, if the drive bracket 71 is a plastic part, a parting line is provided at the end of the first rotating hole 7124 of the drive bracket 71 away from the first mounting plate 421. The separation of the end of the first rotating hole 7124 away from the first mounting plate 421 from the inner ring portion 422 along the axial direction of the first rotating hole 7124 can prevent the inner ring portion 422 from directly impacting the parting line when it rotates or is displaced, thus preventing the drive bracket 71 from breaking at the parting line. At the same time, it can prevent burrs or other protrusions at the parting line from affecting the rotation of the air guide grille 200 and preventing the air guide grille 200 from shaking.

[0095] In some embodiments of the present invention, such as Figure 2As shown, along the axial direction of the first rotating hole 7124, the end of the inner ring portion 422 near the first mounting plate 421 is spaced apart from the first rotating hole 7124. For example, if the first mounting component 42 is a plastic part, a parting line is provided at the end of the inner ring portion 422 near the first mounting plate 421. By separating the end of the inner ring portion 422 near the first mounting plate 421 from the first rotating hole 7124 along the axial direction of the first rotating hole 7124, it can prevent the drive bracket 71 from directly impacting the parting line when the inner ring portion 422 rotates or displaces, thus preventing the first mounting component 42 from breaking at the parting line. At the same time, it can prevent burrs or other protrusions at the parting line from affecting the rotation of the air guide grille 200 and preventing the air guide grille 200 from shaking.

[0096] In some embodiments of the present invention, such as Figure 2 As shown, the inner diameter of the portion of the first rotating hole 7124 that mates with the first mounting component 42 is d1 and satisfies: 5mm ≤ d1 ≤ 20mm. It can be understood that the inner diameter d1 of the portion of the first rotating hole 7124 that mates with the first mounting component 42 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm. This ensures that the first mounting component 42 has sufficient mounting space, while preventing the diameter of the first rotating hole 7124 from being too large, thus avoiding a thin edge on the drive bracket 71 at the location of the first rotating hole 7124 and preventing damage or breakage of the drive bracket 71.

[0097] In some embodiments of the present invention, such as Figure 4 and Figure 6 As shown, the air guide grille 200 also includes a second mounting component 43. The second mounting component 43 is disposed on the side of the air guide grille 200 near the second end 412 in the thickness direction and is connected to the air outlet frame 20. 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 side of the second end 412 of the air guide grille 200 in the thickness direction to the air outlet frame 20, which can reduce the installation difficulty of the air guide grille 200 and also ensure the aesthetics of the side of the air guide grille 200 away from the second mounting component 43 in the thickness direction.

[0098] In some embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9As shown, the air outlet structure 1001 also includes a drive assembly 400. Along the length of the air outlet 202, the drive assembly 400 is located on the side of the air guide grille 200 near the second end 412. The drive assembly 400 includes a drive box 60 and a second drive member 420. At least a portion of the second drive member 420 is located inside the drive box 60. The drive assembly 400 also includes a first drive member 410, which is used to drive the door 300 to rotate. At least a portion of both the first drive member 410 and the second drive member 420 is located inside the drive box 60. The drive box 60 can protect the first drive member 410 and the second drive member 420 to a certain extent, preventing external oil stains, dust, etc. from contaminating the first drive member 410 and the second drive member 420 and preventing damage to the first drive member 410 and the second drive member 420.

[0099] The second drive component 420 is connected to the second mounting assembly 43 and is used to drive the air guide grille 200 to rotate. The switch door 300 can be connected to the output shaft of the first drive component 410, so that the switch door 300 is connected to the drive assembly 400, allowing the switch door 300 to rotate around its rotation axis while supporting and fixing the switch door 300. When the air conditioner 1000 is supplying air, the switch door 300 can be rotated to the position of opening the air outlet to ensure airflow and reduce air volume loss; when the air conditioner 1000 is turned off, the switch door 300 can be rotated to the position of closing the air outlet, which can play a dust prevention role to ensure the cleanliness of the inside of the air conditioner 1000.

[0100] like Figure 8 As shown, the air guide grille 200 can be connected to the output shaft of the second drive component 420, allowing the air guide grille 200 to be connected to the drive assembly 400, supporting and fixing the air guide grille 200 while allowing it to rotate around its axis of rotation. When the air conditioner 1000 supplies air, the air guide grille 200 can rotate to different angles to achieve the desired air outlet structure 1001 in the width direction of the air outlet 202 (e.g., ...). Figure 4 Air is supplied at different angles in the first direction shown, and the air guide grille 200 can play a certain role in preventing dust to ensure the cleanliness of the air conditioner 1000.

[0101] It should be noted that when the air outlet is closed by the door 300, the air guide grille 200 is located inside the door 300, which can ensure the aesthetic appearance of the air conditioner 1000.

[0102] The second drive unit 420 includes a wind guide grille motor 63, an input gear 631, and an output gear 632. The wind guide grille motor 63 is located inside the drive box 60. The drive box 60 can protect the wind guide grille motor 63 to a certain extent, preventing external oil stains, dust, and other contaminants from polluting the wind guide grille motor 63 and avoiding damage to the wind guide grille motor 63.

[0103] The input gear 631 is located inside the drive box 60 and is fixedly connected to the output shaft of the air guide grille motor 63. The output gear 632 is located inside the drive box 60 and meshes with the input gear 631. The output gear 632 is provided with a connecting plate 301, which is used to connect with the air guide grille 200. The connecting plate 301 is located at one axial end of the output gear 632 and at least partially extends out of the drive box 60.

[0104] like Figure 6 , Figure 8 and Figure 9 As shown, the air guide grille 200 can be connected to the connecting plate 301 on the output gear 632. The output gear 632 meshes with the input gear 631, and the input gear 631 is connected to the output shaft of the air guide grille motor 63. The structure of the second drive component 420 is reasonably designed, which can reduce the assembly difficulty and thus improve the assembly efficiency and production efficiency of the drive assembly 400. At the same time, the input gear 631 can serve as an extension of the output shaft of the air guide grille motor 63 and play a transmission role. The output gear 632 meshes with the input gear 631, transmitting the torque output by the air guide grille motor 63 to the input gear 631, which then transmits the torque to the output gear 632. The output gear 632 rotates synchronously with the air guide grille 200, thereby driving the air guide grille 200 to rotate, so as to ensure the reliability and stability of the air guide grille 200 in delivering air at different angles in the width direction of the air outlet.

[0105] Furthermore, such as Figure 8 As shown, the outer diameter of the output gear 632 is H1, and the outer diameter of the input gear 631 is H2, satisfying H1>H2. It can be understood that the outer diameter of the output gear 632 is larger than the outer diameter of the input gear 631, increasing the torque transmitted from the air guide grille motor 63 to the air guide grille 200, thus allowing the air guide grille 200 to have greater rotational force.

[0106] In some embodiments of the present invention, such as Figure 7 and Figure 10 As shown, the air outlet frame 20 has an intermediate support portion 40 located at the air outlet 202. The intermediate support portion 40 is spaced apart from both ends of the air outlet 202 in the length direction. The air guide grille 200 also includes a third mounting component 44. The third mounting component 44 is disposed on one side of the grille body 41 in the thickness direction and is spaced apart from the first end 411 and the second end 412. The third mounting component 44 is rotatably connected to the intermediate support portion 40.

[0107] Understandably, the third mounting component 44 can be located at the middle position along the length of the grille body 41. By setting the third mounting component 44 on one side of the thickness direction of the grille body 41, it is convenient to connect the thickness direction side of the middle position along the length of the air guide grille 200 to the air outlet frame 20. This reduces the installation difficulty of the air guide grille 200, enhances the connection strength and stability between the air guide grille 200 and the support of the air outlet frame 20, and also ensures the aesthetics of the side of the air guide grille 200 away from the third mounting component 44 in the thickness direction. In addition, the third mounting component 44 is rotatably connected to the intermediate support 40, which ensures the rotatability of the air guide grille 200 relative to the air outlet frame 20. 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.

[0108] In some embodiments of the present invention, such as Figure 7 and Figure 10 As shown, the intermediate support portion 40 has a connection hole 401, and 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 disposed in the connection hole 401.

[0109] 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 the side of the third mounting plate 441 facing the second end 412, 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 extends towards the second end 412, i.e., downwards. The connecting hole 401 also extends in the vertical direction. Thus, the mounting ring 442 can cooperate with the connecting hole 401 to form a rotatable 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.

[0110] 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 connecting 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 20. The installation is convenient and the operation is simple, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0111] In some embodiments of the present invention, such as Figure 7 and Figure 10As shown, the third mounting assembly 44 also includes a rotary bearing 443, which is disposed between the mounting ring 442 and the intermediate support portion 40. The rotary bearing 443 separates the mounting ring 442 and the intermediate support portion 40, reducing friction between them and thus reducing frictional heat and wear, thereby extending their service life. Simultaneously, by providing the rotary bearing 443, the stability and reliability of the rotational connection between the mounting ring 442 and the intermediate support portion 40 are improved, thereby ensuring the stability and reliability of the air guide grille 200's rotation in the width direction of the air outlet 202 and the air guidance itself.

[0112] In some embodiments of the present invention, such as Figure 11 and Figure 12 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.

[0113] 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.

[0114] 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.

[0115] In some embodiments of the present invention, such as Figure 11 and Figure 12As 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.

[0116] 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.

[0117] 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.

[0118] In some embodiments of the present invention, such as Figure 7 and Figure 10 As shown, the third mounting assembly 44 also 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 facing the second end 412. In the direction away from the axis of the mounting ring 442, the end face of the third guide rib 444 facing the second end 412 is inclined toward the second end 412.

[0119] 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 second end 412. At the same time, in the direction away from the axis of the mounting ring 442, the lower end face of the third guide rib 444 is inclined toward the second end 412. When the operator fastens the mounting ring 442 into the connection hole 401 from top to bottom, the connection position of the third mounting component 44 and the air outlet frame 20 is in the operator's blind spot. The lower end face of the inclined third guide rib 444 can play a guiding role, which can guide the mounting ring 442 to the top of the connection hole 401 so that it can be fastened into the connection hole 401. This makes it easy for the operator to operate blindly, and the installation is convenient and simple to operate, which can effectively improve the assembly efficiency of the air outlet structure 1001.

[0120] In some embodiments of the present invention, such as Figure 7 and Figure 10 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, so that the end faces of the multiple third guide ribs 444 facing the second end 412 can simultaneously play a guiding role. This enhances the stability of the guiding function of the third guide ribs 444 and also improves the accuracy of guiding the mounting ring 442 into the connecting hole 401, thereby reducing the installation difficulty of the air guide grille 200 and improving the assembly efficiency of the air outlet structure 1001.

[0121] In some embodiments of the present invention, such as Figure 4 , Figure 7 and Figure 10 As shown, the grille body 41 includes vertical guide ribs 415 and horizontal reinforcing ribs 416. Multiple vertical guide ribs 415 are spaced apart along the width of the grille body 41 and extend along the length of the air outlet 202. Multiple horizontal reinforcing ribs 416 are also spaced apart along the length of the air outlet 202 and extend along the width of the grille body 41. The horizontal reinforcing ribs 416 are connected to the vertical guide ribs 415. The staggered arrangement of the horizontal reinforcing ribs 416 and the vertical guide ribs 415 improves the structural strength of the grille body 41 and enhances the airflow guidance effect of the air guide grille 200. This prevents hands or other foreign objects from entering the air outlet duct 201, meeting safety regulations and protecting user safety, thereby improving the user experience. Furthermore, there is no need to install additional components such as wire mesh at the air outlet 202, thus reducing the cost of the air outlet structure 1001 and improving the noise level of the airflow.

[0122] In some embodiments of the present invention, such as Figure 12As shown, the diameter of the inner peripheral wall of the rotary bearing 443 is d2 and satisfies: 5mm ≤ d2 ≤ 20mm. It can be understood that the diameter of the inner peripheral wall of the rotary bearing 443 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm. This ensures that the mounting ring 442 of the third mounting assembly 44 has sufficient mounting space, while preventing the inner peripheral wall diameter of the rotary bearing 443 from being too large, thus avoiding a thinner rotary bearing 443 and preventing breakage.

[0123] In some embodiments of the present invention, such as Figure 10 As shown, the end of the mounting ring 442 near the third mounting plate 441 is located outside the rotary bearing 443. For example, the third mounting plate 441 and the mounting ring 442 are integral plastic parts. A parting line is provided at the end of the mounting ring 442 near the third mounting plate 441. The fact that the end of the mounting ring 442 near the third mounting plate 441 is located outside the rotary bearing 443 can prevent the rotary bearing 443 from directly impacting the parting line when the mounting ring 442 rotates or is displaced, thus preventing the third mounting assembly 44 from breaking at the parting line. At the same time, it can prevent burrs or other protrusions at the parting line from affecting the rotation of the air guide grille 200 and preventing the air guide grille 200 from shaking.

[0124] In some embodiments of the present invention, such as Figures 13-15 As shown, there are multiple air outlet ducts 201 spaced apart along the width of the air outlet frame 20, and multiple air outlets 202 corresponding to the multiple air outlet ducts 201. Setting multiple interconnected air outlet ducts 201 and air outlets 202 can effectively expand the air outlet of the air conditioner 1000 along the width of the air outlet frame 20 (e.g., ...). Figure 15 The air supply range (shown in the left and right directions) and the air outlet area of ​​the air conditioner 1000 are expanded, thereby improving the air supply effect of the air conditioner 1000 and accelerating the cooling or heating efficiency, making the indoor temperature more uniform.

[0125] An air conditioner 1000 according to an embodiment of the present invention is described below.

[0126] An air conditioner 1000 according to an embodiment of the present invention includes the air outlet structure 1001 described above.

[0127] According to an embodiment of the present invention, the air conditioner 1000, by providing an air outlet duct 201 and an air outlet 202 communicating with the air outlet duct 201 on the air outlet frame 20, and by making the grille body 41 detachably and rotatably disposed at the air outlet 202, wherein the rotation axis of the grille body 41 extends along the length direction of the air outlet 202, can realize that the air guide grille 200 guides the airflow and adjusts the air delivery direction in the width direction of the air outlet 202 to meet the user's air delivery needs. At the same time, the air guide grille 200 is rotatably connected to the drive bracket 71. The drive bracket 71 has a first rotation hole 7124 on the side near the first end 411. At least a portion of the first mounting component 42 is rotatably extended into the first rotation hole 7124. At least a portion of the first mounting component 42 can cooperate with the first rotation hole 7124 to form a rotational connection. The structure is simple and easy to implement. This allows the air guide grille 200 to rotate around the axis of the first rotating hole 7124 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.

[0128] In some embodiments of the present invention, such as Figure 1 , Figures 13-15 As shown, the grille body 41 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 20 along its length. The outer edge of the top cover 1002 opposite to the air outlet 202 is arc-shaped and matches the grille body 41. The air outlet 202 and the air outlet frame 20 extend vertically. The top cover 1002 is located at the upper end of the air outlet frame 20 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 is open, which makes it easy for the operator to lift the grille body 41 to a certain height to complete the installation and removal of the air guide grille 200.

[0129] The outer edge of the top cover 1002 opposite to the air outlet 202 is an arc shape that matches the grille body 41. Thus, when the grille body 41 is lifted to a certain height, the grille body 41 and the top cover 1002 can avoid each other, thereby preventing the grille body 41 and the top cover 1002 from colliding with each other, so that the operator can smoothly complete the installation and removal of the air guide grille 200.
