Description

Technical Field

[0001] This disclosure relates to the field of air conditioner technology, and more particularly to an air conditioner. Background Technology

[0002] Ductless air conditioners, as a highly efficient air conditioning device, are widely used in various scenarios such as homes, offices, and commercial spaces. They deliver treated air to different areas through ducts, achieving precise control over indoor temperature, humidity, and air quality. As users' demands for air conditioning experience continue to increase, ductless air conditioners with bidirectional airflow capabilities are gradually becoming one of the mainstream products in the market due to their ability to more flexibly adjust the airflow direction and optimize indoor airflow distribution.

[0003] The core function of a bidirectional air supply duct unit relies on the motion control of its air guide plate. By rotating and opening / closing the air guide plate, airflow can be switched between different vents to meet the air supply needs of different areas. Currently, most bidirectional air supply duct units on the market use a cantilevered structure design, where one end of the air guide plate is connected to the drive shaft, and the other end is suspended in a cantilever state. In practical applications, this structure faces several problems affecting airflow switching performance, leading to unstable force conditions. This instability directly causes the air guide plate to move unevenly, resulting in vibration, which not only affects the user experience but may also generate additional noise. More seriously, uneven force can cause the air guide plate to be difficult to position precisely during opening and closing, resulting in opening / closing angle deviations or jamming. This affects airflow efficiency and the accuracy of airflow direction, failing to fully utilize the advantages of bidirectional air supply. Furthermore, long-term uneven force may even lead to structural deformation of the air guide plate and wear of drive components, reducing the lifespan and reliability of the duct unit.

[0004] Therefore, optimizing the structural design of the air guide plate of the bidirectional air supply duct machine and solving problems such as its unsmooth movement and incomplete opening and closing under gravity and wind pressure has become a key technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, in order to solve the technical problem in the prior art that the air guide plate is not conducive to its reciprocating rotation under the action of its own gravity and the air pressure of the outlet, and that the air guide plate is not smooth and is prone to shaking, this disclosure provides an air conditioner.

[0006] According to a first aspect of the present disclosure, an air conditioner is provided, the air conditioner including a housing, and an air inlet cavity and an air outlet cavity disposed and communicating within the housing, the air inlet cavity including an air inlet, and the air outlet cavity including an air outlet, characterized in that the air outlet includes a first air outlet and a second air outlet, the first air outlet being located on the front side of the housing, and the second air outlet being located on the lower side of the housing; the first air outlet is provided with an upper sliding groove and a lower sliding groove, the upper sliding groove and the lower sliding groove forming independent guide rails with a gap at the position of the first air outlet, and the lower sliding groove extending at least partially to the second air outlet; the air conditioner further includes an upper air guide plate, a first transmission assembly, a lower air guide plate, and a second transmission assembly. The upper air guide plate is connected to at least a portion of the structure of the first transmission group on both sides. The first transmission group is correspondingly installed on the inner side of the upper sliding groove. At least a portion of the structure of the first transmission group slides along the upper sliding groove to drive the upper air guide plate to partially open and close the first air outlet. The lower air guide plate is connected to at least a portion of the structure of the second transmission group on both sides.

At least a portion of the structure of the second transmission group slides along the lower sliding groove to drive the lower air guide plate to partially open and close the first air outlet and to open and close the second air outlet. The upper air guide plate and the lower air guide plate are matched and applied to form a complete opening and closing of the first air outlet.

[0007] In one alternative implementation,

[0009] The sliding groove is constructed as an arc-shaped guide rail. At least a portion of the sliding groove extends to the second air outlet position, at least a portion of the sliding groove extends to the first air outlet position, and at least a portion of the sliding groove extends into the interior of the housing.

[0010] The upper groove interval is located above the lower groove.

[0011] In one alternative implementation,

[0012] The first transmission assembly includes a first gear and a first rack meshing with the first gear. The first gear is installed inside the housing, and the first rack slides in match with the upper sliding groove. The first gear is used to rotate under the drive of the first drive shaft to drive the first rack to slide up and down in an arc-shaped area inside the upper sliding groove.

[0013] In one alternative implementation,

[0014] A first connecting block is connected to each side of the upper air guide plate, and each first connecting block is fastened to a first rack, so that the rotation of the first rack drives the upper air guide plate to rotate accordingly.

[0015] In one alternative implementation,

[0016] The side wall of the first rack has a rack arc groove, and the side wall of the first connecting block has an arc protruding wall. The arc protruding wall is used to extend into the rack arc groove and engage with and position itself in the rack arc groove.

[0017] In one alternative implementation,

[0018] The second transmission assembly includes a second gear set and a second rack meshing with the second gear set. The second gear set is installed inside the housing and is located below the first gear. The second rack slides in match with the lower groove. The second gear set is used to rotate under the drive of the second drive shaft to drive the second rack to slide up and down in an arc-shaped area inside the lower groove.

[0019] In one alternative implementation,

[0020] The second gear set includes a driving gear and an upper driven gear and a lower driven gear that mesh with the driving gear respectively. The upper driven gear and the lower driven gear are respectively located on the side of the driving gear near the lower air guide plate. The upper driven gear is located above the lower driven gear. The driving gear is used to drive the upper driven gear and the lower driven gear to rotate in the same direction. The second rack is configured to mesh with both the upper driven gear and the lower driven gear simultaneously, so that during the rotation of the upper driven gear and / or the lower driven gear, the second rack is driven to slide up and down in the arc-shaped area inside the lower groove.

[0021] In one alternative implementation,

[0022] A second connecting block is connected to each side of the lower air guide plate, and each second connecting block is fastened to a second rack so that the rotation of the second rack drives the lower air guide plate to rotate accordingly.

[0023] In one alternative implementation,

[0024] The side wall of the second rack has a rack arc groove, and the side wall of the second connecting block has an arc protruding wall. The arc protruding wall is used to extend into the rack arc groove and engage with and position itself in the rack arc groove.

[0025] In one alternative implementation,

[0026] The inner wall of one of the rack's arcuate groove and the arcuate protruding wall has a recessed structure, and the other has a protruding structure. The recessed structure and the protruding structure are aligned and configured to restrict the first connecting block from dislodging from the first rack and to restrict the second connecting block from dislodging from the second rack.

[0027] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: In this disclosure, the air conditioner includes a housing, and an air inlet cavity and an air outlet cavity disposed and connected within the housing. The air inlet cavity includes an air inlet, and the air outlet cavity includes an air outlet. The air outlet includes two air outlets: a first air outlet and a second air outlet. The first air outlet is located on the front side of the housing, and the second air outlet is located on the lower side of the housing. Considering the application of a non-cantilever structure to drive the air guide plate to rotate, so as to achieve simultaneous control of the air volume of the two air outlets, specifically, the upper air guide plate slides along the upper sliding groove by the first transmission group, and the lower air guide plate slides along the lower sliding groove (partially extending to the second air outlet) by the second transmission group. The two work together to independently or collaboratively control the opening and closing and air volume of the first and second air outlets, satisfying 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 can also be continuously adjusted by matching the opening degree.

[0028] It should be noted that the non-cantilever structure of the transmission assembly and slide rail provides stable support and guidance for the air guide plate, avoiding cantilever swaying and deformation, reducing friction and abnormal noise, reducing component wear, and improving the operational stability and lifespan of the air guide plate; the independent slide groove design (with gaps between the upper and lower slide grooves and the lower slide groove extending) avoids transmission interference, ensures smooth sliding across the air outlet, and reduces the risk of jamming.

[0029] Furthermore, the upper and lower troughs are integrated into the air outlet area, and the lower trough, in conjunction with the lower air guide plate, can regulate the airflow of the first and second air outlets. This allows for separate installation of the transmission structure within a limited space, reducing redundancy, improving space utilization, and facilitating miniaturization. The transmission assembly connects to both sides of the air guide plate, with a clearly defined installation position, facilitating standardized production and mass assembly, thus improving efficiency. Simultaneously, it enables multi-mode air supply (single first air outlet, single second air outlet, and dual air outlet coordination) to adapt to different scenarios; expanding the air supply coverage area, reducing blind spots, improving indoor temperature uniformity, and enhancing user comfort.

[0030] In addition, the matching sliding scheme of the upper and lower slide grooves with the corresponding transmission groups can distribute the force and extend the service life of the components. The independent slide rail reduces the chain reaction of failure. When one transmission group fails, the other group can work, reducing the risk of overall machine failure and reducing maintenance costs.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0046] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

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

[0049] In order to solve the technical problem that the air guide plate in the prior art is not conducive to its reciprocating rotation under the action of its own gravity and the air pressure of the outlet, and the air guide plate is not smooth and is prone to shaking, this disclosure provides an air conditioner.

[0050] In this disclosure, references Figures 1-7 The air conditioner includes a housing 1, and an air inlet cavity and an air outlet cavity that are connected within the housing 1. The air inlet cavity includes an air inlet, and the air outlet cavity includes an air outlet 2. The air outlet 2 includes a first air outlet 21 and a second air outlet 22. The first air outlet 21 is located on the front side of the housing 1, and the second air outlet 22 is located on the lower side of the housing 1. The first air outlet 21 is provided with an upper sliding groove 3 and a lower sliding groove 4. The upper sliding groove 3 and the lower sliding groove 4 form independent guide rails with a gap at the position of the first air outlet 21. At least a portion of the structure of the lower sliding groove 4 extends to the second air outlet 22. The air conditioner also includes an upper air guide plate 5, a first transmission assembly 6, a lower air guide plate 7, and a second transmission assembly 8. The air guide plate 5 is connected to at least a portion of the structure of the first transmission group 6 on both sides. The first transmission group 6 is correspondingly installed on the inner side of the upper sliding groove 3. At least a portion of the structure of the first transmission group 6 slides along the upper sliding groove 3 to drive the upper air guide plate 5 to partially open and close the first air outlet 21. The lower air guide plate 7 is connected to at least a portion of the structure of the second transmission group 8 on both sides. The second transmission group 8 is correspondingly installed on the inner side of the lower sliding groove 4. At least a portion of the structure of the second transmission group 8 slides along the lower sliding 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, a non-cantilever structure is used to drive the air guide plate to rotate, so as to simultaneously control 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 work together to independently or collaboratively control the opening and closing and air volume of the first and second air outlets 22, so as 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 matching the opening degree.

[0052] It should be noted that the non-cantilever structure of the transmission assembly and slide rail provides stable support and guidance for the air guide plate, avoiding cantilever swaying and deformation, reducing friction and abnormal noise, reducing component wear, and improving the operational stability and lifespan of the air guide plate; the independent slide groove design (the upper and lower slide grooves 4 have a gap and the lower slide groove 4 extends) avoids transmission interference, ensures smooth sliding across the air outlet 2, and reduces the risk of jamming.

[0053] Furthermore, the upper and lower slots 4 are integrated into the air outlet 2 area, and the lower slot 4, in conjunction with the lower air guide plate 7, can regulate the airflow of the first air outlet 21 and the second air outlet 22. This allows for separate installation of the transmission structure within a limited space, reducing redundancy, improving space utilization, and facilitating miniaturization. The transmission assembly is connected to both sides of the air guide plate, with a clear installation position, facilitating standardized production and mass assembly, thus improving efficiency. Simultaneously, it enables multi-mode air supply (single first air outlet 21, single second air outlet 22, and dual air outlets 2 working together) to adapt to different scenarios; expanding the air supply coverage, reducing blind spots, improving indoor temperature uniformity, and enhancing user comfort.

[0054] In addition, the matching sliding scheme of the upper and lower sliding grooves 4 with the corresponding transmission groups can distribute the force and extend the service life of the components. The independent slide rail reduces the chain reaction of failure. When one transmission group fails, the other group can work, reducing the risk of overall machine failure and reducing maintenance costs.

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

[0056] Thus, both the upper and lower sliding grooves 4 are arc-shaped guide rails, perfectly matching 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 angle around the axis or along the arc path to adjust the opening and closing of the air outlet 2 and the air delivery direction). The arc-shaped guide rails provide a "fitting motion trajectory" guide for the transmission groups (first transmission group 6, second transmission group 8), reducing stuttering and shaking when the transmission groups (such as gears, racks, etc.) drive the air guide plates, improving the smoothness and accuracy of the air guide plate angle adjustment. Furthermore, compared to linear guide rails, arc-shaped guide rails allow the air guide plates to maintain "dynamic sealing / opening control" with the air outlets 2 (first air outlet 21, second air outlet 22) during rotation, precisely regulating the airflow (e.g., achieving proportional airflow distribution in different areas of the first air outlet 21).

[0057] It should be noted that the upper slide groove 3 part of the structure enters the interior of the housing 1, using the space inside the housing 1 to "hide" the guide rail structure, avoiding interference with external components (such as conflicts with the front of the air conditioner or other air duct structures), while providing a longer movement path for the transmission group (such as the gears and racks of the first transmission group 6), supporting the upper air guide plate 5 to adjust the opening of the first air outlet 21 to a wider range (from completely closed to completely 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 control the lower part of the first air outlet 21 and the second air outlet 22, to achieve zoned and layered air volume control of the first air outlet 21 (such as small airflow at the top, large airflow at the bottom, or reverse adjustment).

[0058] Furthermore, the downward sliding groove 4 directly acts on the second air outlet 22, allowing the transmission assembly (second transmission assembly 8) of the lower air guide plate 7 to "directly reach" the second air outlet 22, precisely controlling the opening and closing of the second air outlet 22 and the airflow (e.g., when the second air outlet 22 is completely closed, the lower air guide plate 7 slides along the downward sliding groove 4 to the sealed position; when open, it slides to the specified opening degree); the downward sliding groove 4 covers the lower area of ​​the first air outlet 21, working in conjunction with the upper sliding groove 3, allowing the lower air guide plate 7 to participate in the "lower half" airflow of the first air outlet 21. The volume control, in conjunction with the upper air guide plate 5, enables 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, sealing or opening together); similar to the upper slide rail 3, the internal cavity space of the housing 1 is used to "accommodate" the movement of the transmission group, optimizing the internal space layout of the air conditioner (avoiding interference between the guide rail and core components such as the evaporator and fan), while providing 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] Meanwhile, the upper slide 3 and the lower slide 4 are arranged in layers in space (the upper slide 3 is on top and the lower slide 4 is on the bottom), 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 does not interfere with each other: First, it can avoid the transmission group (such as gears and racks) from "jamming and colliding" during the movement, and improve the stability of independent control of the two air guide plates; Second, it can support the independent operation of the upper air guide plate 5 (controlling the upper half of the first air outlet 21 + front side air supply) and the lower air guide plate 7 (controlling the lower half of the first air outlet 21 + lower side air supply of the second air outlet 22), so as to achieve a more flexible air supply mode (such as front side air supply only, lower side air supply only, and front and lower side coordinated air supply).

[0060] In summary, the upper air guide plate 5 and the lower air guide plate 7 work together to independently control the opening and closing of the second air outlet 22, while simultaneously coordinating the complete opening and closing and airflow distribution of the first air outlet 21. This enables coverage of air supply needs in multiple scenarios. For example, during summer cooling, the lower air guide plate 7 opens the second air outlet 22 to achieve "downward air supply" (cold air sinks, improving comfort). During winter heating, the second air outlet 22 is closed, and the opening of the first air outlet 21 is increased to achieve "front-side air supply" (hot air rises, promoting indoor circulation). At the same time, the arc-shaped guide rail reduces transmission wear, the layered spacing avoids interference, and the extended structure optimizes the spatial layout, all contributing to improving the operational stability and component lifespan of the air conditioner.

[0061] Considering the specific structural scheme of the first transmission group 6, in the air conditioner provided in this application embodiment, 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 housing 1, and the first rack 62 slides in match with the upper sliding 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-shaped area inside the upper sliding groove 3.

[0062] Thus, the first transmission group 6 adopts a meshing structure of "first gear 61 + first rack 62". The gear is installed inside the housing 1, and the rack slides in match with the upper sliding groove 3. The gear rotates under the drive shaft. Because the upper sliding groove 3 is an arc-shaped guide rail, the rack can slide up and down along its inner side in an arc-shaped area. This meshing transmission method has a stable transmission ratio and can accurately convert the gear rotation into the arc-shaped sliding of the rack, providing stable and controllable power to the upper air guide plate 5. This makes the opening adjustment of the upper air guide plate 5 to the upper area of ​​the first air outlet 21 more precise, avoids sliding jamming, and ensures the accuracy and stability of the air volume control at the upper part of the first air outlet 21.

[0063] Specifically, this transmission structure, in conjunction with the arc-shaped design of the upper slide groove 3, allows the upper air guide plate 5 to adapt to the arc-shaped 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 gear and rack ensures that the upper air guide plate 5 can accurately respond to the drive under different air supply requirements (such as adjusting the front air supply angle and controlling the upper air volume), and works in conjunction with the lower air guide plate 7 to help realize the full opening and closing function of the first air outlet 21, improving the adaptability of the air conditioner to front air supply scenarios (such as rapid cooling and heating, 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 this application embodiment, a first connecting block 9A is connected to each side of the upper air guide plate 5, and each first connecting block 9A is fastened to 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 upper air guide plate 5 is fastened to the first rack 62 on both sides by the first connecting block 9A, forming a connection structure of "double-end constraint + fastening fixation". Firstly, the double-end constraint formed on both sides of the air guide plate, with connecting blocks on both sides of the air guide plate, can balance the force when the air guide plate moves (avoiding "shaking and deformation" caused by unilateral connection), so that the upper air guide plate 5 slides more stably along the upper slide groove 3 (arc guide rail) under the drive of the first rack 62, reducing "jamming and abnormal noise" caused by uneven force. Secondly, the fastening connection has the advantages of "convenient assembly + micro deformation self-adaptation" compared with bolts, welding and other methods. It is convenient for production assembly (improving production line efficiency) and can "buffer stress" by slightly adjusting the fastening gap when the air guide plate shakes slightly (such as the vibration of the air conditioner), avoiding loosening or breakage of the connection part and ensuring the structural reliability of long-term operation.

[0066] Furthermore, the first rack 62 slides up and down along the upper slide groove 3 (arc-shaped guide rail) in an arc-shaped area. After the upper air guide plate 5 is engaged with the rack via the first connecting block 9A: Firstly, precise synchronization of movement can be achieved. The arc-shaped sliding of the rack can be transmitted to the upper air guide plate 5 without deviation 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 precisely controlled (such as stepless adjustment from "completely closed" to "maximum air delivery angle"); Secondly, It can adapt to air supply in multiple scenarios. Combined with the arc extension of the upper slide groove 3 (covering the first air outlet 21 + the inner cavity of the housing 1), the air guide plate can slide with the rack to realize "front air supply angle switching" (such as horizontal air supply, oblique upward air supply) or "partial area opening and closing" (such as only opening the upper half of the first air outlet 21). With the lower air guide plate 7 to control the second air outlet 22 (lower side), it meets the needs of multiple scenarios such as "rapid cooling on the front side" and "avoiding direct blowing on the lower side", 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 this application embodiment, 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. The arc protruding wall 91 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 arc-shaped groove 101 on the side wall of the first rack 62 and the arc-shaped protruding wall 91 on the side wall of the first connecting block 9A form an "arc-shaped engagement" structure, and the arc-shaped protruding wall 91 achieves precise positioning after extending into the groove. This arc-shaped matching engagement method increases the contact area between the two, disperses the force on the connection part, avoids the local stress concentration problem that is prone to occur in traditional rigid connections, and can effectively resist the radial and axial forces generated when the upper guide plate 5 moves, 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 is adapted to the arc-shaped sliding trajectory of the first rack 62 along the upper sliding groove 3. The contact of the arc surface reduces frictional resistance during movement, making the relative movement of the rack and connecting block smoother and reducing the risk of jamming. At the same time, the precise positioning of the groove and the protruding wall ensures the synchronization of movement between the upper air guide plate 5 and the first transmission group 6, improving the accuracy of the upper air guide plate 5 in adjusting the opening of the first air outlet 21, and providing reliable structural support for the coordinated control of airflow from the dual air outlets 2.

[0070] Considering the specific structural scheme of the second transmission group 8, in the air conditioner provided in this application embodiment, 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 housing 1 and is located below the first gear 61. The second rack 82 slides in match 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 the arc-shaped area inside the lower groove 4.

[0071] Thus, the second transmission group 8 adopts a meshing structure of "second gear set 81 + second rack 82". The gear set is installed inside the housing 1 and located below the first gear 61, and the rack slides in match with the lower groove 4. The gear set rotates under the drive of the second drive shaft, which can stably convert the rotational motion into the second rack 82 sliding up and down along the arc-shaped surface area inside the lower groove 4. The gear and rack meshing transmission ratio is constant, which can precisely control the sliding stroke and speed of the rack, providing a continuous and controllable driving force for the lower air guide plate 7, avoiding slippage or jamming during the transmission process, and ensuring the stability of the movement of the lower air guide plate 7.

[0072] Furthermore, this structural layout is compatible with the extended design of the sliding groove 4. The gear set is located below the first gear 61 to achieve a layered arrangement of the transmission system, avoiding motion interference with the first transmission group 6. The sliding of the second rack 82 along the arc-shaped sliding groove 4 can drive the lower air guide plate 7 to flexibly complete the opening and closing of a part of the first air outlet 21 and the second air outlet 22. Combined with the precise transmission of the gear set, the response speed and accuracy of the lower air guide plate 7 to the air volume control of the dual air outlets 2 are improved, laying the foundation for the realization of the coordinated air supply mode of the dual air outlets 2.

[0073] Considering the specific structural scheme of the second gear set 81, in the air conditioner provided in this application embodiment, the second gear set 81 includes a driving gear 811 and an upper driven gear 812 and a lower driven gear 813 that mesh with the driving gear 811 respectively. The upper driven gear 812 and the lower driven gear 813 are respectively located on the side of the driving gear 811 near the lower air guide plate 7. 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 the arc-shaped area inside the lower groove 4.

[0074] Thus, the second gear set 81 adopts a combination 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 force during the transmission process, reduces the load pressure of a single gear meshing, effectively reduces wear on the gears and rack, improves the durability and operational stability of the transmission structure, and avoids transmission jamming or interruption caused by single-point meshing failure.

[0075] Furthermore, the upper driven gear 812 and the lower driven gear 813 are distributed vertically and synchronously drive the second rack 82. Adapting to the arc-shaped trajectory characteristics of the lower groove 4, this allows the rotational motion of the driving gear 811 to be more evenly converted into the arc-shaped sliding surface of the rack, ensuring the smooth movement of the lower air guide plate 7 when regulating a portion of the first air outlet 21 and the second air outlet 22. Simultaneously, the multi-gear coordinated transmission improves the precision control of the rack's sliding motion, making the lower air guide plate 7 more accurate in adjusting the opening and closing of the dual air outlets 2, further optimizing the response efficiency and reliability of the coordinated airflow 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 this application embodiment, a second connecting block 9B is connected to each side of the lower air guide plate 7, and each second connecting block 9B is fastened to 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, the lower air guide plate 7 is connected to the second rack 82 on both sides by the second connecting block 9B. This symmetrical connection method can balance the force on the lower air guide plate 7 during movement and avoid tilting or shaking caused by a single-sided connection. The fastening structure provides a reliable fixing effect for the connection part, and can stably transmit the arc-shaped sliding of the second rack 82 to the lower air guide plate 7, ensuring that the lower air guide plate 7 does not loosen during the movement of the rack, ensuring the integrity of the transmission path, and improving the structural stability of the lower air guide plate 7 during operation.

[0078] Specifically, this connection scheme is adapted to the coordinated transmission characteristics of the second gear set 81 and the second rack 82. The precise engagement of the double-sided second connecting blocks 9B with the second rack 82 can convert the arc-shaped sliding motion of the rack into the rotational motion of the lower air guide plate 7 without deviation. This allows the lower air guide plate 7 to accurately adjust the opening and closing of a portion of the first air outlet 21, and reliably control the opening and closing of the second air outlet 22. Combined with the adjustment action of the air guide plate 5, this further improves the accuracy and reliability of the coordinated airflow adjustment of the two 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 this application embodiment, 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. The arc protruding wall 91 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 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 and positioning structure. The matching contact of the arc surfaces increases the force-bearing area of ​​the connection part, which can effectively disperse the load generated when the lower guide plate 7 moves, avoid the connection loosening or damage 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, the arc-shaped engagement structure is adapted to the arc-shaped sliding trajectory of the second rack 82 along the lower groove 4. The precise engagement between the arc-shaped protruding wall 91 and the arc-shaped groove 101 of the rack reduces frictional resistance during relative movement, making the transmission smoother and reducing the risk of jamming. At the same time, this positioning method ensures that the arc-shaped sliding of the second rack 82 can be accurately transmitted to the lower air guide plate 7, improving the accuracy of the lower air guide plate 7 in adjusting the opening and closing of a portion of the first air outlet 21 and the second air outlet 22, providing a reliable guarantee for the coordinated control of the two air outlets 2.

[0082] Considering the specific engagement and positioning scheme between the rack and the connecting block, in the air conditioner provided in this application embodiment, 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 protruding structure 91A. The recessed structure 101A and the protruding structure 91A are aligned and configured to restrict the first connecting block 9A from disengaging from the first rack 62, and to restrict the second connecting block 9B from disengaging from the second rack 82.

[0083] In this way, the arcuate groove 101 of the rack and the arcuate protruding wall 91 form a double-locking positioning mechanism through the alignment of the recessed structure 101A and the raised structure 91A. After the raised structure 91A is embedded in the recessed structure 101A, it locks the relative position of the connecting block and the rack in the radial direction, which can effectively resist the separation force generated when the air guide plate moves, significantly reduce the risk of the first connecting block 9A detaching from the first rack 62 and the second connecting block 9B detaching from the second rack 82, and greatly improve the anti-detachment performance and overall stability of the connecting structure.

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

[0085] In summary, the bidirectional air supply duct unit features symmetrical upper and lower arc-shaped sliding grooves on both sides. The upper guide plate 5 uses a single-gear drive, while the lower guide plate 7 uses a stellar gear system drive, ensuring a longer stroke for the rack. All gears are identical, requiring only one motor for each guide plate to drive them independently. The upper and lower guide plates 7 rotate in a circular motion, and the unit can be set to several default positions. The guide plates do not rotate; the gears and racks drive the arc-shaped guide plates to move in a circular motion within the grooves. Furthermore, the guide plates are not cantilevered; their rotational movement within the arc-shaped grooves improves the stress distribution on the guide plates. The gear drive mechanism ensures smoother operation, comprehensively enhancing the reliability of the unit's air outlet switching mechanism. The identical structure of the upper and lower guide plates reduces the number of parts, increases versatility, and lowers the cost of mold making.

[0086] The following diagram further clarifies the specific airflow control of this disclosure:

[0087] like Figure 2 The two guide plates are arranged vertically, with the upper guide plate set to the first position and the lower guide plate set to the second position. The first air outlet 21 is closed and the second air outlet 22 is open, so the unit can deliver air downwards.

[0088] like Figure 3 The two guide plates are in a horizontal position, with the upper guide plate set to the third position and the lower guide plate set to the fourth position. The first air outlet 21 is open and the second air outlet 22 is closed, enabling the unit to deliver air laterally.

[0089] like Figure 4 The two guide plates are in a horizontal position, but the arcs of the two guide plates face the same direction. The upper guide plate is in the third position, and the lower guide plate is in the fifth position. The two air outlets 2 are in the open position, and the unit achieves side-down bidirectional air supply.

[0090] Based on this, considering the functional requirements of the air guide plate in actual application scenarios, the specific structure of the air guide plate includes an outer guide plate and 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 and pinion structures and connecting block structures, each connecting block is fixed to the corresponding outer guide plate with screws. Each connecting block could be combined with the corresponding outer guide plate into a single guide plate part, but this would prevent the air guide plate from being disassembled from the side air vent for after-sales maintenance. Therefore, it is designed as a separate unit for easy disassembly and assembly. Each connecting block has an arc-shaped protruding wall 91, which is inserted into the corresponding arc-shaped groove of the rack and engaged. The protruding wall also cooperates with the slide groove, and the gear and rack mesh to achieve circumferential sliding of the air guide plate. For example, the protruding wall has several protrusions to avoid surface contact with the inner wall of the slide groove, reduce the movement resistance of the air guide plate, and further ensure the stability of the mechanism.
