Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as an air outlet assembly and an air conditioner. Background Technology

[0002] When the air conditioner is running in cooling or heating mode, the air outlet of the indoor unit is open. By rotating the air guide plate, you can only adjust the direction of the airflow, but you cannot adjust the size of the air outlet, so there are limited adjustment methods.

[0003] The related technology discloses an air vent structure, including an air vent component with a first air vent and a panel disposed at the first air vent. The panel includes a first panel and a second panel. The first panel is a non-perforated plate, and the second panel is provided with multiple air outlet holes. The first panel and the second panel are stacked, and the first panel and the second panel are independent of each other and can move relative to each other to adjust the size of the first air vent.

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

[0005] When the first panel and the second panel move relative to each other, they can only change the size of the air outlet, but cannot adjust the air outlet angle.

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

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0036] Unless otherwise stated, the term "multiple" means two or more.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-15 As shown in the figure, this disclosure provides an air outlet assembly, including a fixed ring, a driving ring, and a first baffle. The fixed ring has a first air outlet and a first pivot portion on one side. The driving ring is disposed opposite to the fixed ring and can rotate relative to the fixed ring. The driving ring has a first driving portion. The first baffle has a first end rotatably connected to the first pivot portion and a second end movable along an axis approaching or away from the first air outlet. The first baffle extends and has a first driving engagement portion. The first driving portion engages with the first driving engagement portion. When the driving ring rotates, it drives the first baffle to rotate around the first pivot portion.

[0039] In this embodiment of the disclosure, the air outlet assembly 10 is installed on an air conditioning device such as a fan or air conditioner that has an air outlet.

[0040] The first air outlet of the fixing ring 100 is used to connect with the air outlet at the preset installation position. When the projection of the first baffle 400 on the plane where the first air outlet is located is inside the first air outlet, it blocks part of the air outlet to change the air outlet cross section of the air outlet assembly 10. The first baffle 400 forms a certain angle with the axis of the first air outlet so that the air blown out through the first air outlet changes the air outlet direction under the wall effect of the first baffle 400.

[0041] Specifically, a first pivot portion 110 is provided on one side of the fixed ring 100, and the first end of the first baffle 400 is rotatably connected to the first pivot portion 110. The axis around which the first baffle 400 rotates is parallel to the plane where the first air outlet is located. The plane in which the first baffle 400 rotates is a plane that cuts into the plane where the first air outlet is located. When the first baffle 400 rotates, the second end of the first baffle 400 moves along the axis that is closer to or farther from the first air outlet. When the first baffle 400 moves inward, the obstruction of the first air outlet increases, and the angle with the axis of the first air outlet increases. At this time, the opening of the first air outlet is smaller, and the effect of the first baffle 400 in changing the air outlet direction is enhanced. When the first baffle 400 moves outward, the obstruction of the first air outlet decreases. At this time, the opening of the first air outlet is larger, and the effect of the first baffle 400 in changing the air outlet direction is weakened.

[0042] The drive ring 200 is disposed opposite to the fixed ring 100, and the drive ring 200 can rotate relative to the fixed ring 100. The drive ring 200 is provided with a first drive part 210, and the first baffle 400 is provided with a first drive engagement part 420. The rotation of the drive ring 200 relative to the fixed ring 100 can reduce the space required to drive the first baffle 400 to rotate, thereby reducing the volume of the air outlet assembly 10. When the drive ring 200 rotates, it converts the circular motion into the oscillating operation of the first baffle 400, which can easily drive the first baffle 400 to rotate around the first pivot part 110.

[0043] Using the air outlet assembly 10 disclosed in this application, the air outlet cross section and air outlet angle can be changed by rotating the first baffle 400, providing a variety of means to adjust the air outlet; the rotation of the first baffle 400 is driven by the drive ring 200, which requires little space and the air outlet assembly 10 is relatively small in size.

[0044] Optionally, the air outlet assembly 10 also includes a baffle 600 disposed on the fixing ring 100, with the first end of the baffle 600 connected to the first air outlet, and a plurality of first baffles 400 located in the inner ring of the baffle 600.

[0045] When all the first baffles 400 move to the second position, there will be gaps between two adjacent first baffles 400. Although the multiple first baffles 400 are positioned to avoid the first air outlet, the air guiding effect of the first baffles 400 is weakened. Therefore, a baffle 600 is provided on the chassis 11, with its first end connected to the first air outlet. The multiple first baffles 400 are located in the inner circle of the baffle 600. When the multiple first baffles 400 converge into a cone, the baffle 600 does not affect the focusing air delivery effect of the multiple first baffles 400; when the multiple first baffles 400 move to the second position, both the multiple first baffles 400 and the baffle 600 extend along the air outlet direction, jointly playing a guiding role. The baffle 600, together with the multiple first baffles 400, can play a guiding role, thereby preventing air leakage between two adjacent first baffles 400 of the air outlet assembly 10.

[0046] Optionally, the fixed plate is provided with a pivoting structure, and the fixed plate is rotatably installed in a preset installation position through the pivoting structure, with the rotation direction of the fixed plate along the circumference of the first air outlet.

[0047] When the number of first baffles is small and they are not arranged in a circle, as the first baffles converge inward, an air outlet is formed at the position opposite to the first baffle. The overall air outlet direction of the air outlet assembly is along the length of the first baffle. The fixing ring is rotatable, allowing the air outlet to face different directions, thus adjusting the air outlet angle while changing the size of the air outlet. This further enhances user convenience.

[0048] Optionally, the length of the wind deflector 600 is greater than or equal to the length of the first baffle 400.

[0049] Multiple first baffles 400 act as moving parts. The wind deflector 600, located around the outer ring of the multiple first baffles 400, not only prevents interference between the movement of the first baffles 400 and other components in their pre-installed positions, but also provides physical protection for the multiple first baffles 400, preventing damage during installation and transportation. The length of the wind deflector 600 is greater than or equal to the length of the first baffles 400, ensuring that the first baffles 400 remain completely within the wind deflector 600 when rotated to any position, thus allowing the wind deflector 600 to better perform its protective function.

[0050] Optionally, the inner wall of the wind deflector 600 has multiple embedded grooves, the shape of which is adapted to the shape of the first baffle 400. When the multiple second baffles 500 move to the second position, they are embedded into the multiple embedded grooves one by one.

[0051] When the multiple first baffles 400 rotate to the second position, gaps exist between them, and the inner walls are uneven. This leads to a loss of air kinetic energy, affecting the airflow of the air outlet assembly 10. The inner wall of the baffle 600 has multiple recessed grooves, and the multiple first baffles 400 are inserted into these grooves one by one when they move to the first position. When the baffle 600 and the multiple first baffles 400 work together to guide airflow, the inner wall is relatively smooth, which improves the airflow effect of the air outlet assembly 10.

[0052] Optionally, the inner wall of the wind deflector 600 is constructed with multiple guide ribs.

[0053] When multiple first baffles 400 and wind deflectors 600 work together to guide airflow, adjacent guide ribs form guide grooves, and the air is divided into multiple streams that flow along these grooves. Under the guidance of these multiple guide grooves, even if there are some eddies in the air, it moves as a whole along the air outlet direction. This reduces the kinetic energy loss of the airflow through the air outlet assembly 10, thereby increasing the air delivery distance of the air outlet assembly 10.

[0054] Optionally, the first drive unit 210 includes a first guide groove 211, the distance of the first guide groove 211 from the first end to the second end from the first air outlet gradually increases; the first drive mating unit 420 includes a first drive pin 421, the first drive pin 421 extends into the first guide groove 211, and when the drive ring 200 rotates in the first direction, the distance of the first drive pin 421 from the first air outlet increases, thereby driving the second end of the first baffle 400 to approach the axis of the first air outlet.

[0055] When the drive ring 200 rotates in the first direction, the first drive pin 421 moves from the first end of the first guide groove 211 to the second end of the first guide groove 211. The first drive pin 421 drives the first end of the first baffle 400 to move towards the axis closer to the first air outlet, thereby causing the second end of the first baffle 400 to move away from the axis of the first air outlet. When the drive ring 200 rotates in the second direction, the first drive pin 421 moves from the second end of the first guide groove 211 to the first end of the first guide groove 211. The first drive pin 421 drives the first end of the first baffle 400 to move away from the axis of the first air outlet, thereby causing the second end of the first baffle 400 to move away from the axis of the first air outlet. With this configuration, the drive ring 200 drives the first baffle 400 stably and reliably. Furthermore, the way the first guide groove 211 and the first drive pin 421 cooperate can make the drive ring 200 more flexible in driving the first baffle 400. By changing the inclination of the first guide groove 211, the transmission ratio between the drive ring 200 and the first baffle 400 can be changed. By changing the slope of the first guide groove 211, the first baffle 400 can be rotated at a variable speed while the drive ring 200 rotates at a constant speed.

[0056] Optionally, the angle between the first guide groove 211 and the axis of the first air outlet gradually increases from the first end to the second end.

[0057] Taking the axial direction along the first air outlet as the thickness direction of the first guide groove 211, the first guide groove 211 has two opposing inner edges. The angle between the first guide groove 211 and the axis of the first air outlet refers to the angle between the inner edge along the axis of the first air outlet and the axis of the first air outlet. If they are parallel, the first drive pin 421 will interfere with the inner edge of the first guide groove 211 when it rotates. If there is too much fit allowance between the first guide groove 211 and the first drive pin 421, the position of the first drive pin 421 may be unclear when the drive ring 200 rotates. Specifically, when the first baffle 400 is in the first position, it blocks the air outlet more, and the first drive pin 421 is also more tilted. When the first baffle 400 is in the second position, its length direction is along the axis of the first air outlet, and the first drive pin 421 is less tilted and is roughly parallel to the axis of the first air outlet. The angle between the first guide groove 211 and the air outlet gradually increases from the first end to the second end. The inclination of the first drive pin 421 during the rotation of the first baffle 400 is adapted to the inclination of the first guide groove 211. This reduces the friction between the first guide groove 211 and the first drive pin 421 and allows the first drive pin 421 to rotate to the preset angle more effectively.

[0058] Optionally, the air outlet assembly 10 also includes a mounting ring 300, which is coaxial with the fixed ring 100. The mounting ring 300 and the fixed ring 100 are arranged opposite to each other to form a drive space, and the drive ring 200 is rotatably disposed in the drive space.

[0059] The mounting ring 300 is used to fix the air outlet assembly 10 in a preset installation position, such as the air outlet of a cabinet air conditioner. The chassis 11 consists of the mounting ring 300, the drive ring 200, and the fixing ring 100 in sequence along the air outlet direction, with the drive ring 200 located between the mounting ring 300 and the fixing ring 100. When the drive ring 200 drives the first baffle 400 to rotate, the movement of the drive ring 200 is less likely to interfere with the air outlet assembly 10 or other parts of the air conditioner. The mounting ring 300 and the fixing ring 100 form a driving space, allowing the air outlet assembly 10 to have a neat appearance.

[0060] Optionally, the mounting ring is provided with a pivoting structure, and the air outlet assembly is rotatably mounted in a preset mounting position via the pivoting structure, with the rotation direction of the mounting ring along the circumference of the first air outlet.

[0061] When the number of the first baffles is too small to form a complete circle, they will create an air outlet opening when they come together. The orientation of the air outlet opening can be adjusted by rotating the mounting ring, thereby adjusting the air outlet angle of the air outlet assembly.

[0062] Optionally, the outer edge of the drive ring 200 has teeth; the air outlet assembly 10 also includes a drive gear 240 that meshes with the teeth of the drive ring 200, and the drive gear 240 rotates to drive the drive ring 200 to rotate.

[0063] The outer edge of the drive ring 200 has teeth, and the rotation drive of the drive ring 200 is on the same plane as the drive ring 200, which reduces the overall thickness of the air outlet assembly 10. The drive gear 240 meshes with the teeth on the outer ring of the drive ring 200, and when the drive gear 240 rotates, the drive ring 200 rotates a corresponding number of teeth. This allows for the drive of the drive ring 200 to be driven by a smaller motor, reducing the size and cost of the air outlet assembly 10.

[0064] Optionally, the first portion of the outer edge of the drive ring 200 is constructed with gear teeth.

[0065] When the drive ring 200 moves the first baffle 400 between the first and second positions, the rotation angle of the drive ring 200 is fixed, and the outer edge of the drive ring 200 has a partially toothed structure. This configuration reduces the machining difficulty of the drive ring 200. Furthermore, the partially toothed nature of the drive ring 200 prevents it from rotating beyond its rotation range even if the drive motor malfunctions, thus avoiding the first baffle 400 rotating beyond its rotation range. This also improves the safety of the air outlet assembly 10.

[0066] Optionally, the mounting ring 300 is provided with a first fastening portion 310 extending radially outward; the fixing ring 100 is provided with a second fastening portion 150 extending radially outward, the first fastening portion 310 and the second fastening portion 150 enclosing and defining a gear mounting space, and the drive gear 240 is disposed in the gear mounting space.

[0067] To facilitate the mounting and positioning of the drive gear 240, the mounting ring 300 has a first engaging portion 310 extending radially, and the fixing ring 100 has a second engaging portion 150 extending radially. The first engaging portion 310 and the second engaging portion 150 enclose and define a gear mounting space. A clearance notch is provided on the side of the gear mounting space facing the drive ring 200 to allow the drive gear 240 to mesh with the drive ring 200. This arrangement facilitates the fixing of the drive gear 240. Furthermore, the corresponding first engaging portion 310 and the second engaging portion 150 serve as visual identification markers when the mounting ring 300 and the fixing ring 100 are connected, facilitating the assembly of the air outlet assembly 10.

[0068] Optionally, the air outlet assembly 10 also includes a drive motor, a second fastening part 150 fixed to the retaining ring 100 and drivenly connected to the drive gear 240.

[0069] The drive motor drives the drive gear 240 to rotate, thereby driving the drive ring 200 to rotate. The drive motor is located outside the gear mounting space, and its output shaft is connected to the drive gear 240. The drive motor is connected to the second fastening part 150, that is, the side of the retaining ring 100 used to connect the first baffle 400. In this way, the drive motor does not occupy much installation space, and the air outlet assembly 10 can be fitted to the preset installation position through the retaining ring 100.

[0070] Optionally, the fixed ring 100 is provided with a plurality of first pivoting parts 110, which are arranged circumferentially along the first air outlet; the drive ring 200 is provided with a plurality of first driving parts 210, which are arranged circumferentially along the first air outlet; the air outlet assembly 10 includes a plurality of first baffles 400, which correspond one-to-one with the plurality of first pivoting parts 110 and one-to-one with the plurality of first driving parts 210. When the second ends of the plurality of first baffles 400 are all rotated inward to the first position, they converge into a cone with open ends so that the first air outlet opens at the minimum opening degree. When the second ends of the plurality of first baffles 400 are all moved outward to the second position, the first air outlet opens at the maximum opening degree.

[0071] When the multiple first baffles 400 move to the first position along the axis closer to the first air outlet, the second ends of the multiple first baffles 400 converge into a cone with open ends. The end with the larger cross-section of the cone is designated as the first end, and the end with the smaller cross-section as the second end. The first end of the cone connects to the first air outlet on the chassis 11, and the second end of the cone serves as the overall air outlet of the air outlet assembly 10. At this time, the air outlet cross-section of the air outlet assembly 10 decreases, and the air entering the cone is blown a greater distance under the guiding action of the multiple first baffles 400, thereby achieving focused, long-range air delivery.

[0072] It should be noted that simply reducing the cross-section of the air outlet results in a higher air velocity at the outlet, but also turbulent airflow. Near the outlet, significant kinetic energy is lost due to molecular collisions, leading to a shorter air delivery distance. However, using the air outlet assembly 10 provided in this embodiment, with multiple first baffles 400 converging, each first baffle 400 acts as a guide, allowing the air to form a laminar flow under the wall effect of the first baffles 400. This results in less energy loss during movement, enabling the air to be blown to a greater distance.

[0073] When all the first baffles 400 move to the second position away from the axis of the first air outlet, the second ends of the multiple first baffles 400 disperse. The projection of the second end of each first baffle 400 onto the plane where the first air outlet is located is outside the first air outlet. At this time, the air outlet of the chassis 11 serves as the overall air outlet of the air outlet assembly 10, and the air outlet cross-section of the air outlet assembly 10 is relatively large. Air is directly blown out through the air outlet of the chassis 11 without being disturbed by the multiple first baffles 400, resulting in a large air volume from the air conditioner.

[0074] It should be noted that when the multiple first baffles 400 move between the first and second positions, the projection of the second ends of the multiple first baffles 400 onto the plane of the air outlet is located within the first air outlet. The multiple first baffles 400 converge but cannot form a closed cone with open ends. At this time, the first air outlet of the chassis 11 serves as the air outlet of the entire air outlet assembly 10, and the second ends of the multiple first baffles 400 are located on the air outlet path, thus creating a turbulence effect on the air. The air turbulent by the multiple first baffles 400 is directed to a closer distance and has a gentler feel, thus achieving wedge-shaped turbulence air delivery.

[0075] Using the air outlet component 10 disclosed in this application, the air delivery distance and wind intensity can be adjusted by the movement of multiple first baffles 400, resulting in a variety of air outlet patterns; the positions of the multiple first baffles 400 can be continuously changed, and the air delivery distance and wind intensity can be steplessly adjusted to meet the personalized needs of users in different usage scenarios.

[0076] To achieve both fixing and driving of the multiple first baffles 400, the chassis 11 includes a fixing ring 100 and a driving ring 200. The fixing ring 100 provides mounting positions for the multiple first baffles 400, that is, the multiple first baffles 400 are rotatably connected to the fixing ring 100. The driving ring 200 drives the multiple first baffles 400 to move synchronously to a first position, a second position, or a position between the first position and the second position.

[0077] One side of the fixed ring 100 is provided with a plurality of first pivot portions 110, each of which corresponds one-to-one with a plurality of first baffles 400. The first baffles 400 are rotatably connected to the fixed ring 100 through the first pivot portions 110. For example, the first pivot portion 110 is a bushing, and the first end of the first baffle 400 has a rotating shaft 430. The rotating shaft 430 cooperates with the bushing to achieve the rotatable connection of the first baffle 400. As another example, the first pivot portion 110 is a rotating shaft 430, and the first baffle 400 is provided with a bushing. The bushing cooperates with the rotating shaft 430 to achieve the rotatable connection of the first baffle 400.

[0078] The drive ring 200 is arranged parallel to the fixed ring 100, and the drive ring 200 can rotate in a plane relative to the fixed ring 100. The drive ring 200 is provided with a plurality of first drive parts 210, and each first baffle 400 is provided with a first drive mating part 420. The plurality of first drive parts 210 are mated one-to-one with each other. When the drive ring 200 rotates, the first drive parts 210 move in a circular motion along the plane of the drive ring 200, driving the first drive mating parts 420 to move, thereby driving the first baffle 400 to rotate around the first pivot part 110.

[0079] The chassis 11 includes a fixing ring 100, which fixes multiple first baffles 400, facilitating the installation and positioning of the multiple first baffles 400. The driving ring 200 simultaneously drives the multiple first baffles 400 to move, and the second ends of the multiple first baffles 400 can move to the first position or the second position at the same time, which facilitates the air outlet assembly 10 to change the air outlet mode. The driving ring 200 is coaxial with the fixing ring 100 and can rotate relative to the fixing ring 100. The driving ring 200 requires less space to move, which helps to reduce the volume of the air outlet assembly 10.

[0080] Optionally, the first baffle 400 includes a plate 410, a rotating shaft, and a first drive pin 421, wherein the width of the plate 410 gradually decreases from the first end to the second end; the rotating shaft is disposed at the first end of the plate 410; and the first drive pin 421 is disposed at the first end of the plate 410 or the rotating shaft.

[0081] Multiple first baffles 400 can be assembled into a cone. For a single first baffle 400, the width of its second end is smaller than the width of its first end. Specifically, each first baffle 400 includes a plate 410, which serves as the main body of the first baffle 400. When multiple first baffles 400 are assembled, the plate 410 functions as an enclosure and air guide. The width of the plate 410 gradually decreases from the first end to the second end, so that it can be assembled into a sealed cone when gathered. A rotating shaft is located at the first end of the plate 410, and the rotating shaft engages with the first pivot portion 110 of the fixed ring 100 to rotatably connect the first baffle 400 to the fixed ring 100. A first drive pin 421 serves as a first drive engagement portion 420, with one end connected to the first end of the plate 410 or the rotating shaft, and the other end extending into the first guide groove 211. This arrangement facilitates the drive ring 200 in driving the first baffle 400 to rotate.

[0082] Optionally, the plate 410 includes a windproof portion 411 and a mounting portion 412, wherein the width of the windproof portion 411 gradually decreases from the first end to the second end; the mounting portion 412 is connected to the first end of the baffle, and there is a first included angle between the mounting portion 412 and the windproof portion 411.

[0083] The plate 410 includes a windproof part 411 and a mounting part 412. The windproof parts 411 of multiple first baffles 400 are assembled to form a cone. The mounting part 412 is used to fix the first baffles 400 to the chassis 11.

[0084] The width of the windbreak portion 411 gradually decreases from the first end to the second end, which is beneficial for the windbreak portions 411 of multiple first baffles 400 to be joined together.

[0085] When multiple first baffles 400 are arranged to form a cone, the wind-blocking portion 411 is generally along the axial direction of the first air outlet, and the mounting portion 412 is generally along the radial direction of the first air outlet. There is a first included angle between the mounting portion 412 and the wind-blocking portion 411, allowing the mounting portion 412 to fit snugly against the chassis 11. Since the mounting portion 412 fits snugly against the chassis 11, it is not necessary to drill holes in the chassis 11 to fix the first baffles 400, thus preventing air leakage from the air outlet assembly 10. Furthermore, the large contact area between the mounting portion 412 and the chassis 11 improves the fixation effect of the chassis 11 on the first baffles 400.

[0086] Optionally, the first included angle is greater than 90 degrees.

[0087] When the first included angle is equal to 90 degrees, the length direction of the mounting part 412 is along the radial direction of the first air outlet, while the length direction of the wind-blocking part 411 is along the axial direction of the first air outlet. When the first included angle is greater than 90 degrees, with the mounting part 412 attached to the chassis 11, the second end of the wind-blocking part 411 converges inward, thereby causing the multiple first baffles 400 to be assembled into a cone. This arrangement can further improve the fixing effect of the chassis 11 on the first chassis 11.

[0088] Optionally, the middle portion of the windbreak 411 protrudes toward the first air outlet.

[0089] The middle portion of the windbreak 411 protrudes towards the first air outlet; that is, the angle between the cone and the axis of the first air outlet gradually decreases from the first end to the second end. Inside the cone, the increase in air velocity is greater near the first end and better near the second end. The air is throttled and accelerated at the front of the cone, creating more turbulence, while the velocity change is less at the rear, where the air is rectified by the wall effect at the rear end to reduce turbulence and increase laminar flow. After exiting the first cone, the air can travel a greater distance. This configuration further increases the air delivery distance of the air outlet assembly 10.

[0090] Optionally, the inward side of the plate 410 is provided with an air guide protrusion 413, which extends along the length direction of the first baffle 400.

[0091] The air guide protrusions 413 on the inner surface of the plate 410 are wedge-shaped or triangular, with their width gradually decreasing from the first end to the second end of the plate 410. When multiple first baffles 400 are assembled, two adjacent air guide protrusions 413 form air guide grooves. The portion of the air flowing inside the cone near the inner wall of the cone is divided into multiple streams by the air guide protrusions 413 and flows along multiple air guide grooves. Under the guidance of the multiple first air guide grooves, even if there is a certain amount of vortex in the air, it moves as a whole along the air outlet direction. This reduces the impact of the air near the inner wall of the cone on the flow of other parts of the air, reduces the kinetic energy loss of the air inside the cone, and thus increases the air delivery distance of the air outlet assembly 10.

[0092] Optionally, the plate 410 has two air guide protrusions 413, and an air guide groove is formed between two adjacent air guide protrusions 413.

[0093] The plate 410 has two air-guiding protrusions 413, which can form more air-guiding grooves on the inner wall of the cone. This can further reduce the kinetic energy loss of air in the cone, thereby increasing the air delivery distance of the air outlet assembly 10.

[0094] Optionally, the two air guide protrusions 413 are respectively close to the two sides of the plate 410, and one side of the air guide protrusion 413 serves as the first splicing part 414. When multiple first baffles 400 are spliced ​​together, the air guide protrusions 413 of two adjacent first baffles 400 are spliced ​​together.

[0095] The two air-guiding protrusions 413 of the plate 410 are close to the two sides, and the air-guiding protrusions 413 also serve as structural reinforcements of the first plate 410. When multiple first baffles 400 are assembled, the first baffles 400 are not easily deformed; when air flows through the cone, the first baffles 400 are not easily vibrated.

[0096] After the air guide protrusion 413 approaches the two sides of the plate 410, it is preferable that the air guide protrusion 413 is flush with the sides of the plate 410. In this way, the plate 410 is thicker at the sides. With the thickened sides as the first splicing part 414, when multiple first baffles 400 are spliced, firstly, the first baffles 400 are less likely to deform due to mutual contact; secondly, the side thickness of the plate 410 is thicker, and two adjacent first baffles 400 are less likely to be misaligned or have gaps when spliced.

[0097] Optionally, the outward-facing side of the plate 410 is provided with a wedge-shaped protrusion 440.

[0098] The outer side of the plate 410 is constructed with a wedge-shaped protrusion 440. On one cross section of the first baffle 400, the air guide protrusion 413 on the inner side of the plate 410 and the wedge-shaped protrusion 440 on the outer side make its structure have multiple bends, which can further improve the structural strength of the plate 410.

[0099] Optionally, the width of the wedge-shaped protrusion 440 gradually increases from the first end to the second end of the plate 410, and the width of the air guide groove gradually increases from the first end to the second end of the plate 410, with the wedge-shaped protrusion 440 corresponding to the air guide groove.

[0100] The width of the air guide groove gradually increases from the first end to the second end, while the width of the two air guide protrusions 413 adjacent to the air guide groove gradually decreases from the first end to the second end of the plate 410. The gradually increasing width of the air guide groove results in a gradually expanding air guide cross-section as air flows within it. This ensures that the vortices formed by the air contacting the wall of the air guide groove occur primarily within the groove itself, reducing kinetic energy loss due to contact between the vortices and air at other locations. The wedge-shaped protrusions 440 correspond to the air guide grooves, resulting in a more uniform thickness across the entire plane of the plate 410. This arrangement improves the structural strength of the first baffle 400 while reducing its weight, thus lowering the cost of the air outlet assembly 10.

[0101] Optionally, the rotating shaft is located at the end of the mounting portion 412 away from the windbreak portion 411.

[0102] The rotating shaft is located at the end of the mounting part 412 away from the windshield part 411. When the first baffle 400 rotates, the rotation of the mounting part 412 and the windshield part 411 is all located on one side of the rotating shaft 430. In this way, the first baffle 400 is less likely to interfere with the chassis 11 when it rotates.

[0103] Optionally, the fixing ring 100 is provided with a plurality of first connectors 120 along the circumference of the first air outlet. The two ends of the first connectors 120 are provided with shaft holes. The axis of the shaft holes is parallel to the plane where the first air outlet is located. Each pair of adjacent first connectors 120 serves as a first pivot part 110. The two ends of the rotation shaft of the first baffle 400 are respectively inserted into the two opposite shaft holes of the two adjacent first connectors 120.

[0104] The two ends of the rotation shaft of the first baffle 400 are fixed by two adjacent first connectors 120, so that the first baffle 400 is not easy to deviate when it rotates; each end of each first connector 120 is connected to a first baffle 400, and the number of connectors is equal to the number of first baffles 400. The structure of the fixing ring 100 is simple and the processing difficulty is low.

[0105] Optionally, the shaft hole is provided with a snap-fit ​​notch along the radial direction, and the rotating shaft of the first baffle 400 is snapped into the shaft hole along the snap-fit ​​notch.

[0106] If both ends of the rotating shaft are respectively installed into the shaft hole along the axial direction of the rotating shaft, the rotating shaft will undergo a certain elastic deformation during assembly, or the shaft hole needs to leave an assembly allowance for the rotating shaft. In this case, the first baffle 400 may shift axially when rotating. The shaft hole has a snap-fit ​​notch along the radial direction, the width of which is smaller than the diameter of the rotating shaft. When assembling the first baffle 400, the rotating shaft is snapped into the shaft hole radially through the snap-fit ​​notch, and then clearance-fitted with the shaft hole to achieve a rotatable connection of the first baffle 400. This configuration facilitates the assembly of the first baffle 400 and improves its installation accuracy.

[0107] Optionally, the first connector 120 has a first shaft hole and a second shaft hole, and there is a second included angle between the first shaft hole and the second shaft hole.

[0108] Multiple first baffles 400 can be gathered together to form a cone, and the rotation axes of the multiple first baffles 400 form a regular polygon, thus allowing a larger area shape to be formed with less material. The rotation axis of the first baffle 400 is one side of the regular polygon, and there is a certain angle α between adjacent rotation axes. When the number of first baffles 400 is n, this angle α = 180° - (360° / n). Correspondingly, the second angle between the first shaft hole and the second shaft hole is also α, which better constrains the rotation axes of the first baffles 400, thereby allowing the multiple first baffles 400 to form a cone with a larger air-guiding cross-section at the bottom.

[0109] Optionally, the first shaft hole and the second shaft hole are connected.

[0110] This reduces the difficulty of injection molding the first connector 120 and the amount of material used in injection molding the first connector 120, thereby reducing the cost of the air outlet assembly 10.

[0111] Optionally, each of the two sides of the first baffle 400 is provided with a first splicing part 414, and each two adjacent first baffles 400 can be spliced ​​together by the two first splicing parts 414.

[0112] When all the first baffles 400 move inward to the first position, they combine to form a cone. If there is a gap between two adjacent first baffles 400, air leakage will affect the air delivery effect of the air outlet assembly 10. Each first baffle 400 has a first splicing part 414 at both ends, and two adjacent first baffles 400 are spliced ​​together through the first splicing part 414. This can improve the air delivery effect of the air outlet assembly 10 and reduce the noise generated by air flowing through the gap between two adjacent first baffles 400.

[0113] Optionally, the first splice 414 is made of a flexible material.

[0114] When multiple first baffles 400 move inward to the first position, the first joint 414 between two adjacent first baffles 400 undergoes elastic deformation. This further prevents air leakage from the cone when multiple first baffles 400 converge.

[0115] Optionally, the air outlet assembly 10 further includes a plurality of second baffles 500 arranged circumferentially along the first air outlet and located on the outer ring of the plurality of first baffles 400. The first end of each second baffle 500 is rotatably connected to the fixing ring 100 so that the second end can move in a direction close to or away from the axis of the first air outlet. When the second ends of the plurality of first baffles 400 move inward to the first position, the plurality of second baffles 500 converge inward. When the second ends of the plurality of first baffles 400 move outward to the second position, each second baffle 500 is located between two adjacent first baffles 400.

[0116] Multiple first baffles 400 are moved away from the first position, creating a large gap between adjacent first baffles 400. The air outlet assembly 10 is provided with two rings of baffles: multiple first baffles 400 in the inner ring and multiple second baffles 500 in the outer ring. The multiple second baffles 500 are also distributed circumferentially along the first air outlet, and each second baffle 500 is rotatably connected to the chassis 11. The second end of each second baffle 500 can move along the axis approaching or away from the air outlet.

[0117] When multiple first baffles 400 move inward to a first position, they form a first cone; when multiple second baffles 500 move inward to the first position, they form a second cone. The second cone is located on the outer ring of the first cone. At this time, each second baffle 500 blocks the seam between two adjacent first baffles 400. This arrangement further prevents air leakage at the seam between two adjacent first baffles 400.

[0118] When multiple first baffles 400 move outward to the second position, they form a cylindrical shape, with gaps between adjacent first baffles 400. When multiple second baffles 500 move outward to the second position, they also form a cylindrical shape, with each second baffle 500 blocking the gaps between adjacent first baffles 400. Thus, the first baffles 400 and second baffles 500 form a sealed airflow duct. This improves the airflow guiding effect of the air outlet assembly 10 when the multiple first baffles 400 are in the second position.

[0119] When multiple first baffles 400 are positioned between the first and second positions, the projection of the second end of the first baffle 400 onto the plane of the first air outlet lies within the first air outlet, and the second end of the first baffle 400 acts as a turbulence generator. At the same time, the projection of the second end of the second baffle 500 onto the plane of the first air outlet also lies within the first air outlet, and the second end of the second baffle 500 also acts as a turbulence generator. This further improves the wedge-shaped turbulence-driven airflow effect of the air outlet assembly 10.

[0120] Optionally, when the drive ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, and the movement of the plurality of first baffles 400 precedes the rotation of the plurality of second baffles 500. When the drive ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate outward, and the rotation of the plurality of second baffles 500 precedes the rotation of the plurality of first baffles 400.

[0121] When the drive ring 200 rotates in the first direction, the multiple first baffles 400 and multiple second baffles 500 all rotate inward, and the movement of the multiple first baffles 400 precedes the rotation of the multiple second baffles 500. That is, when the multiple first baffles 400 and multiple second baffles 500 move inward, the multiple first baffles 400 move first, and the multiple second baffles 500 move later. In this way, a diffuser layer is formed between the first baffles 400 of the inner ring and the first baffles 400 of the outer ring. A portion of the air entering the air outlet assembly 10 from the first air outlet first enters the diffuser layer between the first baffles 400 and the second baffles 500 through the air guide gap formed between two adjacent first baffles 400, and then is blown out through the air guide gap formed between two adjacent second baffles 500. The turbulence between the multiple first baffles 400 and the multiple second baffles 500 is buffered by a diffuser layer. After being turbulent by the first baffles 400, the air is mixed in the diffuser layer and then blown out after being turbulent by the second baffles 500. This arrangement forms a diffuser layer, allowing the multiple first baffles 400 and multiple second baffles 500 to better cooperate in achieving the wedge-shaped turbulence function.

[0122] Similarly, when the drive ring 200 rotates in the second direction, the multiple first baffles 400 and multiple second baffles 500 all rotate outward, with the rotation of the multiple second baffles 500 preceding the rotation of the multiple first baffles 400. When both the multiple first baffles 400 and multiple second baffles 500 rotate outward, the multiple second baffles 500 move first, followed by the multiple first baffles 400. This is also to create a diffused airflow interlayer between the inner ring of first baffles 400 and the outer ring of second baffles 500, allowing the multiple first baffles 400 and multiple second baffles 500 to better cooperate in achieving the wedge-shaped turbulence function.

[0123] With this configuration, the movement of the multiple first baffles 400 and the multiple second baffles 500 has a certain time difference, which can form a wind-dispersing interlayer between the multiple first baffles 400 and the multiple second baffles 500, so that the multiple first baffles 400 and the multiple second baffles 500 can better cooperate to achieve the wedge turbulence function.

[0124] Optionally, the outward side of the first baffle 400 is provided with a wedge-shaped protrusion 440, which is embedded between two adjacent second baffles 500 when both the first baffle 400 and the second baffle 500 are rotated to the second position.

[0125] When all the first baffles 400 and the second baffles 500 have moved to the second position, the air outlet opens to its maximum opening, at which point the first baffles 400 and the second baffles 500 form a cylindrical shape. The outward-facing side of each first baffle 400 has a wedge-shaped protrusion 440, the two sides of which abut against two adjacent second baffles 500. In this way, the wedge-shaped protrusion 440 can position the two connected second baffles 500. The inner ring of first baffles 400 and the outer ring of second baffles 500 are locked together by the wedge-shaped protrusion 440, thus preventing either the first baffle 400 or the second baffle 500 from shaking.

[0126] Optionally, when the chassis 11 includes a fixed ring 100 and a drive ring 200, a plurality of second pivot portions 130 are provided circumferentially on one side of the fixed ring 100. The plurality of second pivot portions 130 are located on the outer ring of a plurality of first pivot portions 110. A plurality of second baffles 500 are rotatably connected to the fixed ring 100 through the plurality of second pivot portions 130. The drive ring 200 is also provided with a plurality of second drive portions 220. Each of the plurality of second baffles 500 is provided with a second drive engagement portion 520. The plurality of second drive portions 220 and the plurality of second drive engagement portions 520 are engaged in a corresponding manner. When the drive ring 200 rotates, it drives the plurality of second baffles 500 to rotate.

[0127] One side of the fixing ring 100 is provided with a plurality of first pivot portions 110 and a plurality of second pivot portions 130, with the plurality of second pivot portions 130 located on the outer ring of the plurality of first pivot portions 110. The plurality of first pivot portions 110 are used to rotatably connect a plurality of first baffles 400 to the fixing ring 100, and the plurality of second pivot portions 130 are used to rotatably connect a plurality of second baffles 500 to the fixing ring 100. In this way, the installation and positioning of a plurality of first baffles 400 and a plurality of second baffles 500 can be realized through a single fixing ring 100, simplifying the structure of the air outlet assembly 10.

[0128] The drive ring 200 is provided with multiple second drive parts 220, and each second baffle 500 is provided with a second drive engagement part 520. The multiple second drive parts 220 and multiple second drive engagement parts 520 correspond one-to-one. When the drive ring 200 rotates, it simultaneously drives multiple first baffles 400 and multiple second baffles 500 to rotate. This arrangement allows multiple first baffles 400 and multiple second baffles 500 to rotate simultaneously with one drive ring 200, which is beneficial for the synchronous movement of multiple first baffles 400 and multiple second baffles 500 and simplifies the structure of the air outlet assembly 10.

[0129] Optionally, the mounting ring 300 is constructed with a first groove 320; the fixing ring 100 is constructed with a second groove 160 corresponding to the first groove 320; the driving ring 200 is provided with a sliding post 230, the two ends of the sliding post 230 extending beyond the two sides of the driving ring 200 and respectively into the first groove 320 and the second groove 160.

[0130] The drive ring 200 rotates in the drive space. If the drive ring 200 has surface friction with the mounting ring 300 or the fixed ring 100, the large frictional force will affect the rotation of the drive ring 200. The mounting ring 300 is constructed with a first sliding groove 320, and the fixed ring 100 is constructed with a second sliding groove 160 corresponding to the first sliding groove 320. Both the first sliding groove 320 and the second sliding groove 160 are arc-shaped grooves. The drive ring 200 is also provided with a sliding post 230, the two ends of which extend beyond the two sides of the drive ring 200 and respectively into the first sliding groove 320 and the second sliding groove 160. In this way, on the one hand, the cooperation between the sliding post 230 and the groove defines a sliding track for the drive ring 200, which is beneficial to the rotation of the drive ring 200; on the other hand, the cooperation between the sliding post 230 and the groove reduces the rotational friction of the drive ring 200, allowing the drive ring 200 to rotate more smoothly. Furthermore, the two ends of the sliding column 230 extend into the first sliding groove 320 and the second sliding groove 160 respectively, which helps to maintain a relative distance between the drive ring 200 and the mounting ring 300 and the fixed ring 100. This arrangement improves the concentricity and flatness of the drive ring 200 during rotation, and facilitates the synchronous rotation of the multiple first baffles 400 by the drive ring 200.

[0131] Optionally, when the sliding column 230 is located at the first end of the second slide groove 160, the second ends of the plurality of first baffles 400 rotate inward to the first position and converge into a cone with open ends, at which time the first air outlet is opened at the minimum opening degree; when the sliding column 230 is located at the second end of the second slide groove 160, the second ends of the plurality of first baffles 400 rotate outward to the second position so that the first air outlet is opened at the maximum opening degree.

[0132] Limiting the rotation of the drive ring 200 via the second slide groove 160 achieves the same effect as limiting the rotation of the drive ring 200 via the first slide groove 320.

[0133] Optionally, the mounting ring 300 facing the fixing ring 100 is provided with a plurality of positioning bosses 330 along the circumference of the first air outlet, and the fixing ring 100 is provided with a plurality of positioning mating parts 170 corresponding to the positioning bosses 330, and the plurality of positioning mating parts 170 are respectively attached to the top of the positioning bosses 330.

[0134] The drive ring 200 rotates between the mounting ring 300 and the fixed ring 100, and a certain amount of space needs to be allowed between the mounting ring 300 and the fixed ring 100 to accommodate the rotation of the drive ring 200. Therefore, the mounting ring 300 is provided with a plurality of locating bosses 330 spaced apart along its circumference, and the fixed ring 100 is provided with a plurality of locating mating parts 170 along its circumference. The side of the locating bosses 330 facing the fixed ring 100 abuts against the side of the locating mating parts 170 facing the mounting ring 300. This arrangement facilitates the installation and positioning of the mounting ring 300 and the fixed ring 100 in terms of relative distance and coaxiality.

[0135] Optionally, the drive ring 200 is located on the inner ring of the plurality of positioning bosses 330.

[0136] If the positioning boss 330 passes through the drive ring 200, the drive ring 200 would need to have a corresponding clearance groove, which would affect the structural strength of the drive ring 200. Therefore, the drive ring 200 is located within the inner ring of the multiple positioning bosses 330. In this way, the positioning bosses 330 and the positioning mating part 170 will not interfere with the rotation of the drive ring 200, and the drive ring 200 does not need to have a clearance groove, resulting in higher structural strength.

[0137] Optionally, the top of the positioning boss 330 is provided with a positioning pin 331, and the positioning mating part 170 is provided with a positioning hole 171 corresponding to the positioning pin 331, and the positioning pin 331 is inserted into the positioning hole 171.

[0138] The side of the positioning boss 330 facing the fixing ring 100 is the top of the positioning platform, and the top of the positioning boss 330 is equipped with a positioning pin 331. The positioning mating part 170 has a positioning hole 171 on the side facing the positioning boss 330, and the positioning pin 331 is inserted into the positioning hole 171. This facilitates more accurate installation and positioning between the mounting ring 300 and the fixing ring 100.

[0139] Optionally, the first engaging part 310 and one of the plurality of positioning bosses 330 are integrally formed, and the second engaging part 150 and one of the plurality of positioning mating parts 170 are integrally formed.

[0140] This arrangement facilitates the injection molding of the retaining ring 100 and the mounting ring 300. Furthermore, the positioning mating part 170 and the positioning boss 330 act as reinforcing ribs, improving the structural strength of the first and second engaging parts 150.

[0141] Optionally, the fixing ring 100 is provided with a plurality of first clearance grooves 141, and the plurality of first clearance grooves 141 correspond one-to-one with a plurality of first baffles 400. The first drive pin 421 of the first baffle 400 passes through the first clearance groove 141 and extends into the first guide groove 211 of the drive ring 200.

[0142] When the first baffle 400 rotates, the first drive pin 421 also rotates. The first drive pin 421 passes through the clearance groove opened in the fixed ring 100 and extends into the first guide groove 211 of the drive ring 200. With this arrangement, the first drive pin 421 does not need to extend beyond the drive ring 200 to cooperate with the first guide groove 211 of the drive ring 200, simplifying the structure of the air outlet assembly 10.

[0143] Optionally, the length of the first clearance groove 141 is along the radial direction of the fixed ring 100, and its width is adapted to the size of the first drive pin 421.

[0144] When the first drive pin 421 rotates, it moves radially along the fixed ring 100. The length direction of the first clearance groove 141 is along the radial direction of the fixed ring 100, thus providing rotational space for the first drive pin 421. The width of the first clearance groove 141 is adapted to the size of the first drive pin 421, which restricts the movement of the first drive pin 421 to the radial direction of the mounting ring 300, thereby preventing the friction between the first guide groove 211 and the first drive pin 421 from causing the first drive pin 421 to rotate circumferentially along the fixed ring 100 when the drive ring 200 rotates. This improves the operational reliability of the air outlet assembly 10.

[0145] Optionally, the mounting ring 300 is provided with a third clearance groove 341, the length of the third clearance groove 341 is along the radial direction of the mounting ring 300, and the width is adapted to the size of the first drive pin 421.

[0146] In this way, the third clearance groove 341 of the mounting ring 300 and the first clearance groove 141 of the fixing ring 100 together restrict the movement of the first drive pin 421 to the radial direction of the fixing ring 100. This arrangement can further prevent the first drive pin 421 from moving circumferentially along the fixing ring 100.

[0147] Optionally, the fixing ring 100 is provided with a plurality of second pivot parts 130 at intervals along the circumference of the first air outlet. The plurality of second pivot parts 130 are located on the outer ring of the plurality of first pivot parts 110. The plurality of second baffles 500 are rotatably connected to the fixing ring 100 through the plurality of second pivot parts 130.

[0148] Multiple first pivots 110 are used to connect multiple first baffles 400, and multiple second pivots 130 are used to connect multiple second baffles 500. Both the multiple first baffles 400 and the multiple second baffles 500 are connected to the retaining ring 100, which simplifies the structure of the air outlet assembly 10 and reduces its volume.

[0149] Optionally, the drive ring 200 is provided with a plurality of second guide grooves 221, and the first end of the second baffle 500 is provided with a second drive pin 521. The second drive pin 521 extends into the second guide groove 221, and when the drive ring 200 rotates in both directions, it also drives the second baffle 500 to rotate in both directions.

[0150] The first guide groove 211 is used to drive the first baffle 400 to rotate, and the second guide groove 221 is used to drive the second baffle 500 to rotate. The cooperation between the second drive pin 521 and the second guide groove 221 can be the same as the cooperation between the first drive pin 421 and the first guide groove 211. With this arrangement, when the drive ring 200 rotates, it simultaneously drives multiple first baffles 400 and multiple second baffles 500 to rotate, improving the integration level of the air outlet assembly 10.

[0151] Optionally, the fixing ring 100 has a plurality of second clearance grooves 142, which are located on the outer ring of a plurality of first clearance grooves 141, and the second drive pin 521 passes through the second clearance grooves 142 and extends into the second guide groove 221.

[0152] When the second baffle 500 rotates, the second drive pin 521 also rotates. The second drive pin 521 passes through the second clearance groove 142 opened in the fixed ring 100 and extends into the second guide groove 221 of the drive ring 200. With this arrangement, the second drive pin 521 does not need to extend beyond the drive ring 200 to cooperate with the second guide groove 221 of the drive ring 200, simplifying the structure of the air outlet assembly 10.

[0153] Optionally, the mounting ring 300 has multiple third clearance slots 341 corresponding to multiple first clearance slots 141, and the first drive pin 421 passes through the first guide slot 211 and extends into the third clearance slot 341.

[0154] The third clearance groove 341 cooperates with the first clearance groove 141 to limit the movement of the first drive pin 421 along the circumferential direction of the fixed ring 100. This can better restrict the rotation of the first drive pin 421 to its preset rotation plane and avoid excessive local stress, deformation or breakage of the first drive pin 421.

[0155] Optionally, the mounting ring 300 has multiple fourth clearance slots 342 corresponding to multiple second clearance slots 142, and the second drive pin 521 passes through the second guide slot 221 and extends into the fourth clearance slot 342.

[0156] The fourth clearance groove 342 cooperates with the second clearance groove 142 to limit the movement of the second drive pin 521 along the circumferential direction of the fixed ring 100. This can better restrict the rotation of the second drive pin 521 to its preset rotation plane and avoid excessive local stress, deformation or breakage of the second drive pin 521.

[0157] Optionally, the outer ring of the fixing ring 100 protrudes outward to form an annular step 180, a plurality of second pivots 130 are disposed above the annular step 180, and a plurality of first pivots 110 are disposed on the inner ring of the fixing ring 100.

[0158] The outer ring of the fixing ring 100 is used to connect multiple second baffles 500, and the inner ring is used to connect multiple first baffles 400. When multiple first baffles 400 are spliced ​​together, gaps are easily generated near the fixing ring 100. These gaps include the gaps between two adjacent first baffles 400 and the gaps between the first baffles 400 and the fixing ring 100. Therefore, the fixing ring 100 is provided with an annular step 180, with the outer ring of the fixing ring 100 higher than the inner ring. That is, multiple first connectors 120 are located below the step, and multiple second connectors are located above the step. The gaps of the multiple first baffles 400 near the fixing ring 100 are blocked by the sidewall of the annular step 180. This arrangement improves the airtightness when multiple first baffles 400 are spliced ​​together, thereby improving the air outlet effect of the air outlet assembly 10. Furthermore, the pivot position of the first baffle 400 is below the step, and the pivot position of the second baffle 500 is above the step, so even if the two are close together, rotational interference is unlikely to occur. The annular step 180 reduces the distance between the first baffle 400 and the second baffle 500, thereby improving the airtightness of the air outlet assembly 10.

[0159] Combination Figure 1-2As shown, this embodiment of the present disclosure provides an air conditioner, including a housing 710, a fan box 720, and the aforementioned air conditioner. The housing 710 has an accommodating space and a second air outlet. The fan box 720 is disposed in the accommodating space and has a third air outlet. The fan box 720 and the housing 710 form a sandwich. The aforementioned air outlet assembly 10 is disposed in the sandwich. The first air outlet of the air outlet assembly 10 corresponds to the third air outlet of the fan box 720, and the air outlet direction of the air outlet assembly 10 is towards the second air outlet.

[0160] The air conditioner includes a housing 710 and a fan box 720. The housing 710 has an accommodating space, and the fan box 720 is disposed within the accommodating space. The independently configured fan box 720 can increase the static pressure of the air conditioner's outlet air, which is beneficial for increasing the air volume and extending the air delivery distance. The housing 710 has a second air outlet, and the fan box 720 has a third air outlet. The second air outlet also serves as the overall air outlet of the air conditioner. The first air outlet of the air outlet assembly 10 is connected to the third air outlet of the fan box 720. The air outlet assembly 10 is disposed between the second and third air outlets to guide the air blown from the third air outlet of the fan box 720 to the second air outlet of the housing 710 at a certain angle. When the multiple first baffles 400 move to the first position, their second ends converge, thus achieving focused, far-focused air delivery. When the multiple first baffles 400 move to the second position, their second ends disperse, thus achieving a wider range of gentle air delivery. When the multiple first baffles 400 are between the first and second positions, their tips act as turbulence, achieving wedge-shaped turbulent air delivery. Structurally, the fan housing 720 and the shell 710 form a sandwich, with the air outlet assembly 10 disposed within this sandwich. Thus, the movement of the first baffles 400 or the second baffles 500 of the air outlet assembly 10 occurs neither inside the fan housing 720 nor outside the shell 710, making it less susceptible to interference with the movement of the various moving parts of the air outlet assembly 10.

[0161] Using the air conditioner provided in this embodiment, the air outlet assembly 10 has an adjustable air outlet duct cross-section, allowing the air delivery distance and airflow intensity to be changed by adjusting the cross-section of the air outlet duct. Specifically, with the fan speed constant, decreasing the cross-section of the air outlet duct increases the air delivery distance and enhances the airflow intensity; increasing the cross-section of the air outlet duct decreases the air delivery distance and weakens the airflow intensity. The adjustable cross-section of the air outlet duct allows for adjustment of the air delivery distance and airflow intensity without changing the fan speed, increasing the means to change the airflow pattern.

[0162] The air outlet assembly 10 has moving parts to change the air outlet cross-section of the air outlet duct. The air outlet assembly 10 is set in the interlayer. The movement of the moving parts will not interfere with the internal components of the fan box 720, which improves the stability of the air conditioner operation. The movement of the moving parts will not be exposed outside the housing 710, making the air conditioner more aesthetically pleasing. The air outlet assembly 10 can be operated by opening the housing 710, which facilitates the assembly and maintenance of the air conditioner.

[0163] Optionally, the fan housing 720 includes a first housing 721, a second housing 722, and a fan. The first housing 721 has a third air outlet; the second housing 722 is connected to the first housing 721 and has an air inlet; the fan is disposed in the second housing 722 and is used to drive air to flow from the air inlet to the third air outlet.

[0164] The first housing 721 has the aforementioned third air outlet, and the second housing 722 has an air inlet. The distance between the third air outlet and the air inlet is relatively large, reducing the risk of air short-circuiting and promoting better air circulation. A fan is located in the second housing 722. When the fan rotates, it creates static pressure that drives air from the air inlet into the second housing 722 and then out through the third air outlet of the first housing 721. Inside the second housing 722, there is significant turbulence due to the fan blades. After flowing from the second housing 722 through the first housing 721, the first housing 721 acts as a rectifying unit, increasing laminar flow and allowing the air to travel a greater distance after exiting through the third air outlet. This configuration reduces fan noise and increases the air delivery distance of the air conditioner.

[0165] Optionally, the bottom of the first housing 721 is connected to the top of the second housing 722, and the third air outlet and air inlet are located on different sides of the fan housing 720.

[0166] The air conditioner provided in this embodiment has an air outlet with a shape that is relatively close in length and width, preferably circular. The first housing 721 is located above the second housing 722, and the third air outlet is located above the air inlet. The third air outlet is higher, allowing for a larger coverage area. The third air outlet and the air inlet are located on different sides of the fan housing 720, which further avoids short-circuiting of the return air, thereby improving air circulation. For example, in the operating state, the third air outlet is located on the front side of the fan housing 720, and the air inlet is located on the rear side of the fan housing 720. In the operating state, the front side of the air conditioner faces the user, while the rear side does not. This gives the air conditioner a cleaner appearance.

[0167] Optionally, the air conditioner also includes a first air outlet 711, which is disposed at the third air outlet, and the chassis 11 is disposed on the outer ring of the first air outlet 711.

[0168] The base 11 of the air outlet assembly 10 is fixed to the fan housing 720. There are some structural protrusions and gaps at the joint between the base 11 and the fan housing 720. A first air outlet duct is provided to smoothly guide the air blown from the third air outlet into the air outlet duct of the air outlet assembly 10. This arrangement avoids air leakage at the joint between the air outlet assembly 10 and the fan housing 720, reduces air kinetic energy loss, and improves the air delivery efficiency of the air conditioner.

[0169] Optionally, the air conditioner also includes a second air outlet 712, which is disposed at the second air outlet, and a plurality of first baffles 400 are located in the inner ring of the second air outlet 712.

[0170] When the multiple first baffles 400 move outward to the second position, the second air outlet duct 712 is located on the outer ring of the multiple first baffles 400. The air blown out through the air outlet duct of the air outlet assembly can be smoothly blown out through the second air outlet under the guidance of the second air outlet duct 712. This arrangement can further improve the air outlet effect of the air outlet assembly.
