Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and in particular to an air conditioner. Background Art

[0002] Ducted air conditioners, as highly efficient air conditioning devices, are widely used in a variety of settings, including homes, offices, and commercial spaces. They deliver treated air to different areas through ducts, enabling precise control of indoor temperature, humidity, and air quality. As users' expectations for air conditioning experience continue to rise, ducted air conditioners with bidirectional air supply capabilities are becoming a mainstream product in the market, offering more flexible adjustment of airflow direction and optimized indoor airflow distribution.

[0003] The core functionality of a two-way air duct unit relies on the motion control of the air guide plate. By flipping the air guide plate and coordinating the opening and closing movements, air supply switching between different air outlets can be achieved, thereby meeting the air supply needs of different areas. Currently, the air guide plates of common two-way air duct units on the market mostly adopt a cantilever structure design around the axis, that is, one end of the air guide plate is connected to the drive shaft, and the other end is suspended in the air in a cantilever state. In actual application, this structure faces many problems that affect the air supply switching performance, which in turn leads to unstable stress conditions. This unstable stress condition directly causes the air guide plate to switch unsmoothly and easily cause jitter, which not only affects the user experience but also may generate additional noise. More seriously, the unbalanced force makes it difficult for the air guide plate to accurately position during the opening and closing process, resulting in opening and closing angle deviations or jamming problems, which in turn affects the air supply efficiency and the accuracy of the air supply direction, making it impossible to fully utilize the advantages of two-way air supply. Long-term uneven force may even cause deformation of the air guide plate structure, wear of drive components, and other failures, reducing the service life and reliability of the duct unit.

[0004] Therefore, how to optimize the structural design of the air guide plate of the two-way air supply duct machine and solve the problems of its uneven movement and inadequate opening and closing under the action of gravity and wind pressure has become a key technical problem that needs to be solved urgently by technical personnel in this field.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0048] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0049] In order to solve the technical problems in the prior art that the air guide plate is not conducive to its reciprocating flipping motion under the action of its own gravity and the air outlet pressure, and the air guide plate is not switched smoothly and is prone to shaking, the present disclosure provides an air conditioner.

[0050] In this disclosure, reference Figure 1-Figure 7 The air conditioner includes a shell 1, and an air inlet cavity and an air outlet cavity connected to each other in the shell 1, the air inlet cavity includes an air inlet, and the air outlet cavity includes an air outlet 2, wherein the air outlet 2 includes a first air outlet 21 and a second air outlet 22, the first air outlet 21 is located at the front side of the shell 1, and the second air outlet 22 is located at the lower side of the shell 1; the first air outlet 21 is provided with an upper slide 3 and a lower slide 4, the upper slide 3 and the lower slide 4 form a guide rail independent of each other with a gap at the position of the first air outlet 21, and at least part of the structure of the lower slide 4 extends to the second air outlet 22; the air conditioner also includes an upper air guide plate 5, a first transmission group 6, a lower air guide plate 7 and a second transmission group 8; the upper guide The two sides of the wind plate 5 are connected to at least part of the structure of the first transmission group 6, and the first transmission group 6 is correspondingly installed on the inner side of the upper slide groove 3. At least part of the structure of the first transmission group 6 slides along the upper slide groove 3 to drive the upper air guide plate 5 to partially open and close the first air outlet 21; the two sides of the lower air guide plate 7 are connected to at least part of the structure of the second transmission group 8, and the second transmission group 8 is correspondingly installed on the inner side of the lower slide groove 4. At least part of the structure of the second transmission group 8 slides along the lower slide groove 4 to drive the lower air guide plate 7 to partially open and close the first air outlet 21, and to open and close the second air outlet 22; the upper air guide plate 5 and the lower air guide plate 7 are matched and applied to form a complete opening and closing of the first air outlet 21.

[0051] In this way, it is considered to use a non-cantilever structure to drive the air guide plate to rotate, so as to achieve simultaneous regulation of the air volume of the two air outlets 2. Specifically, the upper air guide plate 5 slides along the upper slide groove 3 by the first transmission group 6, and the lower air guide plate 7 slides along the lower slide groove 4 (partially extending to the second air outlet 22) by the second transmission group 8. The two can independently or collaboratively control the opening and closing and air volume of the first and second air outlets 22 to meet different air supply scenarios on the front and lower sides, such as rapid temperature adjustment on the front side and avoiding direct blowing on the lower side. The air volume of the first air outlet 21 can also be continuously adjusted by opening matching.

[0052] It should be pointed out that the non-cantilever structure of the transmission group and the slide rail provides stable support and guidance for the air guide plate, avoids cantilever shaking and deformation, reduces friction and abnormal noise, reduces component wear, and improves the operating stability and life of the air guide plate; the independent slide groove design (there is a gap between the upper and lower slide grooves 4 and the lower slide groove 4 is extended) avoids transmission interference, ensures smooth sliding across the air outlet 2, and reduces the risk of jamming.

[0053] Furthermore, the upper and lower sliding grooves 4 are integrated into the air outlet 2 area, and the configuration of the lower sliding groove 4 can be combined with the lower air guide plate 7 to regulate the air volume of the first air outlet 21 and the second air outlet 22. This allows the transmission structure to be installed separately in a limited space, reducing redundancy, improving space utilization, and facilitating miniaturization. The transmission group is connected to both sides of the air guide plate, and the installation position is clear, facilitating standardized production and batch assembly, thereby improving efficiency. At the same time, it can achieve multi-mode air supply (single first air outlet 21, single second air outlet 22, and dual air outlets 2 coordinated) to adapt to different scenarios, expand the air supply coverage, reduce blind spots, improve indoor temperature uniformity, and enhance user comfort.

[0054] In addition, the matching sliding scheme of the upper and lower slide grooves 4 and the corresponding transmission groups can disperse the force and extend the life of the components. The independent slide rails reduce the chain reaction of failures. When one transmission group fails, the other group can work, reducing the risk of failure of the entire machine and reducing maintenance costs.

[0055] Considering the specific structural scheme of the upper slide groove 3, in the air conditioner provided in the embodiment of the present application, the upper slide groove 3 is constructed as an arc-shaped guide rail, and at least part of the structure of the upper slide groove 3 extends into the inner cavity of the shell 1, and at least part of the structure of the upper slide groove 3 extends to the position of the first air outlet 21; the lower slide groove 4 is constructed as an arc-shaped guide rail, and at least part of the structure of the lower slide groove 4 extends to the position of the second air outlet 22, and at least part of the structure of the lower slide groove 4 extends to the position of the first air outlet 21, and at least part of the structure of the lower slide groove 4 extends to the interior of the shell 1; the upper slide groove 3 is located above the lower slide groove 4.

[0056] In this way, the upper and lower sliding grooves 4 are both curved guide rails, which are highly adapted to the rotation / sliding trajectory of the air guide plates (upper air guide plate 5, lower air guide plate 7) (the air guide plates need to change their angles around the axis or along the curved path to adjust the opening and closing of the air outlet 2 and the direction of air supply). Among them, the curved guide rails provide a "fitting motion trajectory" guide for the transmission group (first transmission group 6, second transmission group 8), so that when the transmission group (such as gears, racks and other structures) drives the air guide plates to move, it reduces jamming and shaking, and improves the smoothness and accuracy of the air guide plate angle adjustment; in addition, compared with linear guide rails, the curved guide rails allow the air guide plates to always maintain "dynamic sealing / opening control" with the air outlet 2 (first air outlet 21, second air outlet 22) during the rotation process, and accurately control the air volume (such as achieving the proportional distribution of air volume in different areas of the first air outlet 21).

[0057] It should be pointed out that part of the structure of the upper slide groove 3 enters the interior of the shell 1, and uses the space in the inner cavity of the shell 1 to "hide" the guide rail structure to avoid interference with external components (such as conflict with the front face of the air conditioner or other air duct structures). At the same time, it provides a longer movement path for the transmission group (such as the gear and rack of the first transmission group 6), supporting the upper air guide plate 5 to adjust the opening of the first air outlet 21 in a wider range (from fully closed to fully open, or to achieve multi-angle air supply switching); the upper slide groove 3 directly covers part of the area of ​​the first air outlet 21, so that the transmission group of the upper air guide plate 5 (such as the first transmission group 6) can "precisely act" on the upper area of ​​the first air outlet 21, and cooperate with the lower air guide plate 7 to regulate the lower part of the first air outlet 21 and the second air outlet 22, so as to realize the partitioned and layered air volume control of the first air outlet 21 (such as small wind at the top, strong wind at the bottom, or reverse adjustment).

[0058] Furthermore, the lower slide groove 4 acts directly on the second air outlet 22, so that the transmission group (second transmission group 8) of the lower air guide plate 7 can "directly reach" the second air outlet 22, and accurately control the opening and closing and air volume of the second air outlet 22 (for example, when the second air outlet 22 is completely closed, the lower air guide plate 7 slides along the lower slide groove 4 to a sealed position; when opened, it slides to a specified opening); the lower slide groove 4 covers the lower area of ​​the first air outlet 21, and cooperates with the upper slide groove 3 to allow the lower air guide plate 7 to participate in the wind in the "lower half" of the first air outlet 21. The air volume is regulated and the upper air guide plate 5 is cooperated with to realize the complete opening and closing of the first air outlet 21 (the upper and lower air guide plates 7 respectively cover the upper and lower halves of the first air outlet 21, and seal or open together); similar to the upper slide 3, the inner cavity space of the shell 1 is used to "accommodate" the movement of the transmission group, optimize the internal space layout of the air conditioner (avoid interference between the guide rail and core components such as the evaporator and the fan), and at the same time provide a sufficient movement path for the large-angle rotation of the lower air guide plate 7 (such as switching from the second air outlet 22 to the lower part of the first air outlet 21).

[0059] At the same time, the upper slide groove 3 and the lower slide groove 4 are arranged in layers and intervals in space (the upper slide groove 3 is on the upper side and the lower slide groove 4 is on the lower side), so that the movement space of the first transmission group 6 of the upper air guide plate 5 and the second transmission group 8 of the lower air guide plate 7 do not interfere with each other: first, it can avoid "stuck and collided" of the transmission group (such as gears and racks) during movement, and improve the stability of independent control of the dual air guide plates; second, it can support the upper air guide plate 5 (controlling the upper half of the first air outlet 21 + front air supply) and the lower air guide plate 7 (controlling the lower half of the first air outlet 21 + lower side air supply) to move independently, thereby realizing a more flexible air supply mode (such as front side air supply only, lower side air supply only, front side + lower side coordinated air supply).

[0060] In summary, the upper air guide plate 5 cooperates with the lower air guide plate 7 to independently control the opening and closing of the second air outlet 22, and coordinately control the complete opening and closing and air volume distribution of the first air outlet 21; it can cover the air supply needs of multiple scenarios, such as in summer cooling, the lower air guide plate 7 opens the second air outlet 22 to achieve "downward air supply" (cold air sinks to improve physical comfort); when heating in winter, the second air outlet 22 is closed and the opening of the first air outlet 21 is increased to achieve "front air supply" (hot air rises to promote indoor circulation); at the same time, the arc guide rail reduces transmission wear, the layered intervals avoid interference, and the extended structure optimizes the spatial layout, which together improve the operating stability and component life of the air conditioner.

[0061] Considering the specific structural scheme of the first transmission group 6, in the air conditioner provided in the embodiment of the present application, the first transmission group 6 includes a first gear 61 and a first rack 62 meshing with the first gear 61. The first gear 61 is installed in the shell 1, and the first rack 62 slides in matching with the upper slide groove 3. The first gear 61 is used to rotate under the drive of the first drive shaft to drive the first rack 62 to slide up and down in the arc surface area inside the upper slide groove 3.

[0062] Thus, the first transmission group 6 adopts a meshing structure of "first gear 61 + first rack 62". The gear is installed in the housing 1, and the rack slides in conjunction with the upper chute 3. The gear rotates under the drive shaft. Because the upper chute 3 is an arc-shaped guide rail, the rack can slide up and down along its inner arc surface. This meshing transmission method has a stable transmission ratio and can accurately convert the rotation of the gear into the arc-shaped sliding of the rack. It provides smooth and controllable power to the upper air guide plate 5, allowing the upper air guide plate 5 to more accurately adjust the opening of the upper area of ​​the first air outlet 21, avoiding sliding jams and ensuring the accuracy and stability of air volume control above the first air outlet 21.

[0063] Specifically, this transmission structure, combined with the curved design of the upper chute 3, allows the upper air guide plate 5 to adapt to the curved contour of the first air outlet 21, enabling flexible opening and closing of a portion of the first air outlet 21. The stable transmission of the rack and pinion ensures that the upper air guide plate 5 can accurately respond to different air supply requirements (such as adjusting the front air supply angle and controlling the upper air volume). It works in conjunction with the lower air guide plate 7 to facilitate the full opening and closing of the first air outlet 21, improving the air conditioner's adaptability to front-side air supply scenarios (such as rapid cooling and heating, and directional air supply), and optimizing the user's air supply experience.

[0064] Considering the specific connection scheme between the upper air guide plate 5 and the first rack 62, in the air conditioner provided in the embodiment of the present application, a first connecting block 9A is connected to both sides of the upper air guide plate 5, and each first connecting block 9A is respectively engaged with a first rack 62, so that the rotation of the first rack 62 drives the upper air guide plate 5 to rotate accordingly.

[0065] In this way, the two sides of the upper air guide plate 5 are connected to the first rack 62 through the first connecting block 9A, forming a "double-end constraint + snap-fit ​​fixation" connection structure. First, the double-end constraint is formed on both sides of the air guide plate, and connecting blocks are connected on both sides of the air guide plate, which can balance the force during the movement of the air guide plate (avoiding "swaying and deformation" caused by unilateral connection), so that the upper air guide plate 5 can slide more stably along the upper slide groove 3 (arc guide rail) under the drive of the first rack 62, reducing "stuckness and abnormal noise" caused by uneven force; second, the snap-fit ​​connection is adopted. Compared with bolts, welding and other methods, the snap-fit ​​structure has the advantages of "easy assembly + slight deformation self-adaptation" - it is convenient for production and assembly (improving production line efficiency), and when the air guide plate shakes slightly (such as vibration during operation of the air conditioner), the "buffer stress" can be slightly adjusted through the snap-fit ​​gap to avoid loosening or breaking of the connection parts, thereby ensuring the structural reliability of long-term operation.

[0066] Furthermore, the first rack 62 "slides up and down in an arc-shaped area" along the upper slide groove 3 (arc-shaped guide rail), and the upper air guide plate 5 is buckled with the rack through the first connecting block 9A: firstly, precise synchronization of movement can be achieved, and the arc-shaped sliding of the rack can be "transmitted without deviation" to the upper air guide plate 5 through the connecting block, so that the rotation angle and sliding trajectory of the air guide plate are completely matched with the rack, and the opening of the first air outlet 21 (front side) can be accurately controlled (such as stepless adjustment from "completely closed" to "maximum air supply angle"); secondly , which can adapt to multi-scene air supply. Combined with the arc extension of the upper slide groove 3 (covering the first air outlet 21 + the inner cavity of the shell 1), the air guide plate can slide with the rack to achieve "front air supply angle switching" (such as horizontal air supply, oblique upward air supply) or "partial area opening and closing" (such as opening only the upper half of the first air outlet 21). Cooperating with the lower air guide plate 7 to regulate the second air outlet 22 (lower side), it meets the needs of multiple scenarios such as "fast cooling on the front side" and "avoiding direct blowing on the lower side", thereby improving the richness of air supply modes and user experience.

[0067] Considering the specific connection scheme between the first rack 62 and the first connecting block 9A, in the air conditioner provided in the embodiment of the present application, the side wall of the first rack 62 has a rack arc groove 101, and the side wall of the first connecting block 9A has an arc protruding wall 91, which is used to extend into the rack arc groove 101 and engage with the rack arc groove 101 for positioning.

[0068] In this way, the rack arc groove 101 on the side wall of the first rack 62 and the arcuate protruding wall 91 on the side wall of the first connecting block 9A form an "arc-shaped engagement" structure, and the arcuate protruding wall 91 is inserted into the groove to achieve precise positioning. This arc-shaped matching engagement method increases the contact area between the two, disperses the force at the connection point, and avoids the localized stress concentration problem that is prone to traditional rigid connections. It can effectively resist the radial and axial forces generated by the movement of the upper air deflector 5, significantly improving the stability and anti-loosening ability of the connection between the first rack 62 and the first connecting block 9A, and ensuring efficient force transmission during the transmission process.

[0069] Furthermore, this engaging structure adapts to the arcuate sliding trajectory of the first rack 62 along the upper chute 3. The contact of the arcuate surface reduces friction during movement, making the relative movement between the rack and the connecting block smoother and reducing the risk of jamming. Furthermore, the precise positioning of the groove and the protruding wall ensures the synchronization of the movement of the upper air guide plate 5 and the first transmission group 6, improving the accuracy of the upper air guide plate 5's adjustment of the opening of the first air outlet 21 and providing reliable structural support for the coordinated control of the air volume of the dual air outlets 2.

[0070] Considering the specific structural scheme of the second transmission group 8, in the air conditioner provided in the embodiment of the present application, the second transmission group 8 includes a second gear group 81 and a second rack 82 meshing with the second gear group 81. The second gear group 81 is installed in the shell 1, and the second gear group 81 is located below the first gear 61. The second rack 82 slides in matching with the lower groove 4. The second gear group 81 is used to rotate under the drive of the second drive shaft to drive the second rack 82 to slide up and down in an arc surface on the inner side of the lower groove 4.

[0071] Thus, the second transmission group 8 employs a meshing structure consisting of a second gear group 81 and a second rack 82. The gear group is mounted within the housing 1, below the first gear 61, and the rack 82 slides in alignment with the lower groove 4. Driven by the second drive shaft, the gear group rotates, stably converting the rotational motion into the up-and-down sliding of the second rack 82 along the curved surface inside the lower groove 4. The gear-rack meshing transmission ratio is constant, allowing precise control of the rack's sliding stroke and speed, providing continuous and controllable driving force for the lower air deflector 7, preventing slippage or jamming during transmission and ensuring the stability of the lower air deflector 7.

[0072] Furthermore, this structural layout is compatible with the extended design of the lower chute 4. The gear set is located below the first gear 61, achieving a layered arrangement of the transmission system and avoiding motion interference with the first transmission set 6. The second rack 82 slides along the arcuate lower chute 4, driving the lower air guide plate 7 to flexibly open and close a portion of the first air outlet 21 and the second air outlet 22. Combined with the precise transmission of the gear set, this improves the response speed and accuracy of the lower air guide plate 7 in controlling the air volume of the dual air outlets 2, laying the foundation for the implementation of a coordinated air supply mode for the dual air outlets 2.

[0073] Considering the specific structural scheme of the second gear group 81, in the air conditioner provided in the embodiment of the present application, the second gear group 81 includes a driving gear 811 and an upper driven gear 812 and a lower driven gear 813 respectively meshing with the driving gear 811. The upper driven gear 812 and the lower driven gear 813 are respectively located on the side of the driving gear 811 close to the lower air guide plate 7, and the upper driven gear 812 is located above the lower driven gear 813. The driving gear 811 is used to drive the upper driven gear 812 and the lower driven gear 813 to rotate in the same direction. The second rack 82 is configured to be able to mesh with the upper driven gear 812 and the lower driven gear 813 at the same time, so that during the rotation of the upper driven gear 812 and / or the lower driven gear 813, the second rack 82 is driven to slide up and down in an arc surface area on the inner side of the sliding groove 4.

[0074] Thus, the second gear set 81 adopts a combined structure of "driving gear 811 + upper driven gear 812 + lower driven gear 813." The driving gear 811 simultaneously drives the two driven gears to rotate in the same direction, and both driven gears mesh with the second rack 82. This multi-gear meshing transmission method increases the contact area between the gears and the rack, disperses the forces during the transmission process, reduces the load pressure of a single gear meshing, effectively reduces wear on the gears and racks, improves the durability and operational stability of the transmission structure, and avoids transmission jams or interruptions caused by single-point meshing failure.

[0075] Furthermore, the upper driven gear 812 and the lower driven gear 813, positioned vertically and synchronously driving the second rack 82, adapt to the arcuate trajectory of the lower slide chute 4. This more evenly converts the rotational motion of the driving gear 811 into the arcuate sliding motion of the rack, ensuring smooth movement of the lower air deflector 7 when regulating a portion of the first air outlet 21 and the second air outlet 22. Furthermore, the coordinated transmission of multiple gears enhances the precision control of the rack's sliding motion, allowing the lower air deflector 7 to more accurately adjust the opening and closing of the dual air outlets 2, further optimizing the responsiveness and reliability of the coordinated air volume control of the dual air outlets 2.

[0076] Considering the specific connection scheme between the two sides of the lower air guide plate 7 and the second rack 82, in the air conditioner provided in the embodiment of the present application, a second connecting block 9B is connected to both sides of the lower air guide plate 7, and each second connecting block 9B is respectively engaged with a second rack 82, so that the rotation of the second rack 82 drives the lower air guide plate 7 to rotate accordingly.

[0077] In this way, both sides of the lower air deflector 7 are connected to the second rack 82 through the second connecting blocks 9B. This bilaterally symmetrical connection balances the forces acting on the lower air deflector 7 during movement, preventing tilting or shaking caused by a unilateral connection. The snap-fit ​​structure provides a reliable fixation for the connection, stably transmitting the arcuate sliding motion of the second rack 82 to the lower air deflector 7. This ensures that the lower air deflector 7 does not loosen during the movement of the rack, safeguarding the integrity of the transmission path and improving the structural stability of the lower air deflector 7.

[0078] Specifically, this connection scheme adapts to the coordinated transmission characteristics of the second gear set 81 and the second rack 82. The precise engagement of the second connecting blocks 9B on both sides with the second rack 82 accurately converts the arcuate sliding motion of the rack into the rotational motion of the lower air deflector 7 without deviation. This enables the lower air deflector 7 to accurately complete the opening and closing adjustment of a portion of the first air outlet 21 while reliably achieving the opening and closing control of the second air outlet 22. In conjunction with the control action of the upper air deflector 5, this further improves the precision and reliability of the coordinated air volume adjustment of the dual air outlets 2.

[0079] Considering the specific connection scheme between the second rack 82 and the second connecting block 9B, in the air conditioner provided in the embodiment of the present application, the side wall of the second rack 82 has a rack arc groove 101, and the side wall of the second connecting block 9B has an arc protruding wall 91, which is used to extend into the rack arc groove 101 and engage with the rack arc groove 101 for positioning.

[0080] In this way, the rack arc groove 101 on the side wall of the second rack 82 and the arc protruding wall 91 on the side wall of the second connecting block 9B form an arc-shaped locking positioning structure. The matching contact of the arc surface increases the force-bearing area of ​​the connection part, which can effectively disperse the load generated when the lower air guide plate 7 moves, avoid loosening or damage of the connection caused by local stress concentration, and significantly enhance the structural stability and fatigue resistance of the connection between the second rack 82 and the second connecting block 9B.

[0081] Furthermore, this arcuate engagement structure adapts to the arcuate sliding trajectory of the second rack 82 along the lower sliding groove 4. The precise engagement of the arcuate protruding wall 91 with the rack arcuate groove 101 can reduce frictional resistance during relative motion between the two, making transmission smoother and reducing the risk of jamming. At the same time, this positioning method ensures that the arcuate sliding of the second rack 82 can be accurately transmitted to the lower air deflector 7, improving the accuracy of the lower air deflector 7's opening and closing regulation of a portion of the first air outlet 21 and the second air outlet 22, providing reliable protection for the coordinated regulation of the dual air outlets 2.

[0082] Considering the specific engagement and positioning scheme between the rack and the connecting block, in the air conditioner provided in the embodiment of the present application, the inner wall of one of the rack arc groove 101 and the arc protruding wall 91 has a recessed structure 101A, and the other has a raised structure 91A. The recessed structure 101A and the raised structure 91A are arranged in alignment with each other, and are used to limit the first connecting block 9A from falling off the first rack 62, and to limit the second connecting block 9B from falling off the second rack 82.

[0083] Thus, the rack arc groove 101 and the arcuate protruding wall 91 form a dual locking and positioning mechanism through the alignment of the recessed structure 101A and the raised structure 91A. When the raised structure 91A engages with the recessed structure 101A, it radially locks the relative position of the connecting block and the rack, effectively resisting the separation force generated by the movement of the air deflector. This significantly reduces the risk of the first connecting block 9A being dislodged from the first rack 62 and the second connecting block 9B being dislodged from the second rack 82, significantly improving the anti-fall performance and overall stability of the connecting structure.

[0084] Furthermore, this concave-convex positioning design ensures a secure connection without compromising the smooth transmission characteristics of the arc-shaped engagement structure. The precise alignment of the concave and convex helps calibrate the assembly position of the connecting block and the rack, ensuring that they maintain a correct meshing relationship during the arc-shaped sliding process. This avoids transmission noise or precision degradation caused by relative displacement deviation, providing long-term and stable structural support for the precise control of the dual air outlets 2 by the upper and lower air guide plates 7.

[0085] In summary, two upper and lower arc chutes are symmetrically set on the left and right sides of the two-way air supply duct machine, and the upper air guide plate 5 is set with a single gear transmission. When the upper and lower air guide plates 7 have the same rack length, the lower air guide plate is set with a star gear transmission, which ensures that the rack of the lower air guide plate 7 can complete a longer stroke. At the same time, the gears are exactly the same, so only one motor is needed for the upper and lower parts to meet the independent drive requirements of the upper and lower air guide plates 7. The upper and lower air guide plates 7 rotate in a circle, and the unit can be set to several default positions. The air guide plate does not have a flipping motion, and the gear rack drives the arc air guide plate to move in a circle in the chute; and the air guide plate is not a cantilever structure, and it rotates and moves in the circular chute, which improves the force condition of the air guide plate. The mechanism adopts gear transmission, and the movement is smoother, which comprehensively improves the reliability of the air outlet switching motion mechanism of the unit; the upper and lower air guide plates have the same structure, the parts are streamlined, and the versatility is strong, which can reduce the cost of part mold making.

[0086] The following is a further understanding of the specific air volume control of the present disclosure in conjunction with the accompanying drawings:

[0087] like Figure 2 The two guide plates are arranged longitudinally, the upper guide plate is set to the first position, the lower guide plate is set to the second position, the first air outlet 21 is closed, the second air outlet 22 is open, and the unit realizes downward air supply.

[0088] like Figure 3 , the two guide plates are in a horizontal state, the upper guide plate is set to the third position, the lower guide plate is set to the fourth position, the first air outlet 21 is open, the second air outlet 22 is in a closed state, and the unit realizes lateral air supply.

[0089] like Figure 4 , the two guide plates are in a horizontal state, but the arc directions of the two guide plates are the same, the upper guide plate remains in the third position, the lower guide plate is set to the fifth position, the two air outlets 2 are in the open state, and the unit realizes side-down two-way air supply.

[0090] Based on this, and considering the functional requirements of the air deflector in actual application scenarios, the specific structure of the air deflector includes an outer guide plate and a foam 10 attached to the inner side of the outer guide plate. For example, the foam 10 is attached to the inner wall of the outer guide plate. Combined with the aforementioned rack structures and connecting block structures, each connecting block is fixed to the corresponding outer guide plate with screws. Each connecting block can be combined with the corresponding outer guide plate into a guide plate part, but in this way, the air deflector cannot be removed from the side air outlet during after-sales maintenance. Therefore, it is designed to be split for easy disassembly and assembly; each connecting block is provided with an arc-shaped protruding wall 91, into which a rack is inserted and clamped in the corresponding arc-shaped groove. The protruding wall also cooperates with the slide groove, and the gear rack is engaged and transmitted, thereby realizing the circumferential sliding of the air deflector. For example, the protruding wall is provided with a number of protrusions to avoid surface contact with the inner wall of the slide groove, reduce the movement resistance of the air deflector, and further ensure the stability of the mechanism movement.
