[0002] Currently, the air outlet methods of ordinary ducted air conditioners are mainly side air outlet or bottom air outlet. With the continuous expansion of functional requirements, users have increasingly higher requirements for the performance of ducted air conditioners. However, the existing side air outlet ducted air conditioners have limited air delivery distance in practical applications, making it difficult to effectively deliver airflow to the far end of the room, resulting in poor room heating effect and obvious temperature differences in different areas of the room. Summary of the Invention

The second upper baffle protrudes from one end of the upper arc-shaped wind deflector near the side air outlet and protrudes outward from the upper arc-shaped wind deflector. When the upper arc-shaped baffle assembly is rotated to open the upper air outlet area, the first upper baffle protrusion abuts against the first sealing protrusion, and the second upper baffle protrusion abuts against the second sealing protrusion.

[0022] 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.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0024] 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.

[0025] Currently, the air outlet methods of ordinary ducted air conditioners are mainly side-discharge or bottom-discharge. With the continuous expansion of functional requirements, users have increasingly higher performance requirements for ducted air conditioners. However, the existing side-discharge ducted air conditioners have limited air delivery distance in practical applications, making it difficult to effectively deliver airflow to the far end of the room, resulting in poor room heating effect, obvious temperature differences in different areas of the room, and large air delivery blind spots, which cannot meet the requirements of uniform airflow distribution.

[0026] Furthermore, existing research on dual-outlet ducted air conditioners mainly focuses on the switching between side and bottom air outlet modes or the implementation of dual-outlet modes. However, while adding related structures to expand functionality, current technologies often significantly impact the airflow and noise levels of the side outlet. Although this improves the functionality of the ducted air conditioner to some extent, it also has a noticeable negative impact on the original side outlet performance.

[0027] Firstly, such as Figure 1-9 As shown, to address the aforementioned technical problems, this application provides an air outlet structure for a ducted air conditioner, comprising: an air outlet housing 10 having a side air outlet 110 located on the side and a bottom air outlet 120 located on the bottom; an upper arc-shaped baffle assembly 20 rotatably disposed inside the side air outlet 110 for opening or blocking the upper air outlet area of ​​the side air outlet 110; and a lower baffle bracket assembly rotatably disposed inside the side air outlet 110 for opening the lower air outlet area of ​​the side air outlet 110 and blocking the lower air outlet 120; in the side air outlet remote air delivery mode, rotating the lower baffle bracket assembly blocks the lower air outlet 120, and rotating the upper arc-shaped baffle assembly 20 partially or completely blocks the upper air outlet area, thereby reducing the air outlet area of ​​the side air outlet 110 and increasing the air delivery distance.

[0028] It should be noted that in the side-discharge far-reaching air supply mode, by rotating the lower baffle bracket assembly to block the lower air outlet 120, and simultaneously rotating and adjusting the upper arc-shaped baffle assembly 20 to block the area of ​​the upper air outlet area of ​​the side air outlet 110, the overall air outlet area of ​​the side air outlet 110 is reduced. According to the principles of fluid mechanics, reducing the air outlet area can increase the air outlet velocity, thereby increasing the air supply distance, enabling the airflow to be effectively delivered to the far areas of the room, improving the room heating effect, reducing the indoor temperature difference, and thus achieving energy-saving effects.

[0029] It should be noted that when adding dual-outlet functionality, existing technologies often significantly impact the airflow and noise of the side outlet due to the added structure. This solution, through a rotating baffle structure, achieves multi-mode switching while maintaining the integrity of the main structure of the side outlet 110. Furthermore, it optimizes air delivery performance by adjusting the air outlet area, rather than simply adding a blocking structure. This allows for functional expansion while maintaining or improving the side outlet performance. By rotating and adjusting the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, flexible switching between various air delivery modes, such as side outlet remote air delivery, conventional side outlet, and bottom outlet, can be achieved to meet the needs of different usage scenarios.

[0030] In some embodiments, the upper arc-shaped baffle assembly 20 includes an upper arc-shaped baffle 210 and an upper baffle bracket 220. The upper arc-shaped baffle 210 has a convex arc surface in the direction of the side air outlet 110. One end of the upper baffle bracket 220 near the side air outlet 110 is connected to the inner side surface of the upper arc-shaped baffle 210, and the other end away from the side air outlet 110 is rotatably connected to the air outlet housing 10.

[0031] It should be noted that the upper arc-shaped wind deflector 210 has a convex arc surface in the direction of the side air outlet 110. The convex arc surface (the back is a concave arc surface) structure has better aerodynamic characteristics than a flat or concave surface. When the airflow passes through the convex arc surface, it can smoothly turn along the arc surface, reduce airflow separation and vortex generation, thereby reducing wind resistance and airflow noise and improving air supply efficiency.

[0032] It should be noted that, as Figure 7 , 8 As shown in Figures 9 and 10, the end of the upper wind deflector bracket 220 near the side air outlet 110 is connected to the inner side of the upper arc-shaped wind deflector 210, and the end away from the side air outlet 110 is rotatably connected to the air outlet housing 10. This connection method allows the upper arc-shaped wind deflector 210 to be angled around the rotation axis, thereby precisely controlling the shielding area of ​​the upper air outlet area and flexibly adjusting the air outlet area of ​​the side air outlet 110, thereby adjusting the air outlet speed and air delivery distance. The upper wind deflector bracket 220 can be multiple (such as 2, 4, 6, etc.) rods intersecting in the air outlet housing 10. The rod bracket has a small obstruction area for airflow, and airflow can pass smoothly through the gaps between the rods, reducing airflow turbulence and eddies, reducing wind resistance and airflow noise, and improving air delivery efficiency.

[0033] In some embodiments, the lower baffle bracket assembly includes a central arc-shaped baffle assembly 30 and a bottom baffle plate 40. The central arc-shaped baffle assembly 30 is rotatably disposed inside the side air outlet 110, and is used to open or cover the upper area of ​​the lower air outlet area and the inner air outlet area of ​​the lower air outlet 120. One end of the bottom baffle plate 40 is rotatably disposed between the side air outlet 110 and the lower air outlet 120, and the other end is slidably connected to the outer surface of the central arc-shaped baffle assembly 30, and is used to open or cover the lower area of ​​the lower air outlet area and the outer air outlet area of ​​the lower air outlet 120. In the side air outlet mode, rotating the upper arc-shaped baffle assembly 20 opens the upper air outlet area, and rotating the central arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, covering the lower air outlet 120. In the lower air outlet mode, rotating the upper arc-shaped baffle assembly 20 covers the upper air outlet area, and rotating the central arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, covering the lower air outlet area.

[0034] It should be noted that, as Figure 2 , 3As shown in Figures 4, 5, 6, and 7, through the independent control and coordinated operation of the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, the following can be achieved: 1) Side air outlet mode: The upper arc-shaped baffle assembly 20 opens the upper air outlet area, and the middle arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet 120, and all airflow is discharged from the side air outlet 110; 2) Lower air outlet mode: The upper arc-shaped baffle assembly 20 blocks the upper air outlet area, and the middle arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet 120, and all airflow is discharged from the side air outlet 110; 0 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet area, and all airflow is discharged from the lower air outlet 120; 3) Dual air outlet mode: the upper arc baffle assembly 20 opens the upper air outlet area, and the middle arc baffle assembly 30 drives the bottom baffle plate 40 to rotate, opening the lower air outlet 120, and airflow is discharged from both the side air outlet 110 and the lower air outlet 120 at the same time; the three modes switch smoothly and do not interfere with each other, which can meet the diverse air supply needs of different seasons and different scenarios.

[0035] It should be noted that the lower baffle bracket assembly divides the lower air outlet area into an upper and a lower region: the middle arc-shaped baffle assembly 30 controls the upper region of the lower air outlet area and the inner air outlet area of ​​the lower air outlet 120; the bottom baffle plate 40 controls the lower region of the lower air outlet area and the outer air outlet area of ​​the lower air outlet 120. Through zone control, the air outlet area of ​​the lower air outlet area can be finely adjusted, thereby flexibly controlling the air outlet speed and airflow distribution. Furthermore, if zone control is not used, a large baffle plate would be required to simultaneously shield both the lower air outlet area (which has a large area) and the lower air outlet 120 (which is located in a dispersed manner). The baffle assembly covers the entire area, while through zone control, the middle arc-shaped baffle assembly 30 is only responsible for shielding the upper area of ​​the lower air outlet zone and the inner air outlet zone of the lower air outlet 120; the bottom baffle 40 is only responsible for shielding the lower area of ​​the lower air outlet zone and the outer air outlet zone of the lower air outlet 120. Each baffle only needs to cover its corresponding zone area, and the area of ​​a single baffle is significantly reduced, so that the baffle assembly is decomposed from a large and complex structure into two small and simple structures, making the shape of each baffle more regular, the structure simpler, and the overall volume smaller, which is conducive to the miniaturization and weight reduction of the entire duct air conditioner.

[0036] It should be noted that one end of the bottom baffle 40 is slidably connected to the outer side of the middle arc-shaped baffle assembly 30, forming a linkage transmission structure. Only one drive source is needed to control both baffles simultaneously, simplifying the drive mechanism and reducing costs and failure rates. The rotation centers of the middle arc-shaped baffle assembly 30 and the upper arc-shaped baffle assembly 20 do not coincide, allowing them to rotate and be controlled independently without interference. This avoids motion interference or mutual constraints that may occur due to the coincidence of rotation centers, resulting in simple control logic and clear motion trajectories. The two rotation centers can be selected at their optimal positions according to the internal space structure of the air outlet housing 10. The staggered layout allows each baffle assembly to occupy a different space area during rotation, making full use of the scattered space inside the housing and facilitating the miniaturization of the entire unit. Furthermore, since the two baffle assemblies can be adjusted independently, various air supply modes such as side air outlet mode, side air outlet far-reaching air supply mode, bottom air outlet mode, and dual air outlet mode can be freely combined to meet the diverse needs of different usage scenarios.

[0037] In some embodiments, the central arc-shaped baffle assembly 30 includes a central arc-shaped baffle 320 and a central baffle bracket 310; the central arc-shaped baffle 320 has a concave arc surface in the direction of the side air outlet 110; one end of the central baffle bracket 310 near the side air outlet 110 is connected to the inner side surface of the central arc-shaped baffle 320, and the other end away from the side air outlet 110 is rotatably connected to the air outlet housing 10.

[0038] It should be noted that, as Figure 4 As shown, when the side air outlet mode is activated and the upper air outlet area is open, the central arc-shaped baffle assembly 30 shields the lower air outlet area. At this time, the concave arc surface is opposite to or tangential to the main airflow direction, allowing the airflow to flow smoothly along the concave arc surface, avoiding the formation of right-angle obstructions or vortex areas. This effectively reduces wind resistance and airflow noise, ensuring the efficiency and comfort of the side air outlet. Furthermore, the concave arc surface structure has higher bending stiffness than a flat surface, effectively resisting airflow impact and deformation during long-term use, ensuring the shielding accuracy and sealing effect of the lower air outlet area, and improving the reliability and lifespan of the assembly.

[0039] It should be noted that the middle baffle bracket 310 can be multiple (such as 2, 4, 6, etc.) rods intersecting within the air outlet housing 10. The rod bracket has a small obstruction area for airflow, allowing airflow to pass smoothly through the gaps between the rods, reducing airflow turbulence and eddies, lowering wind resistance and airflow noise, and improving air delivery efficiency.

[0040] It should be noted that, as Figure 2 , 3As shown, in the downward air outlet mode: the upper arc-shaped baffle assembly 20 shields the upper air outlet area, the middle arc-shaped baffle assembly 30 shields the lower air outlet area, and the bottom baffle 40 opens the lower air outlet 120. At this time, although both the convex and concave arc surfaces are shielded, they together form a continuous airflow turning channel: the convex arc surface smoothly guides the airflow impacting it downwards, and the concave arc surface receives the airflow from above, further collects and turns it. The airflow flows smoothly through the bottom baffle 40 to the bottom lower air outlet 120, which can reduce the energy loss and vortex generation of the airflow during the turning process and improve the air supply efficiency of the downward air outlet mode.

[0041] In some embodiments, the air outlet structure of the duct unit further includes at least one sliding connection mechanism, which includes a longitudinal slide groove 2104 and a sliding buckle 3201. The longitudinal slide groove 2104 is provided on the outer side of the arc-shaped wind baffle 320 and extends along the width direction of the arc-shaped wind baffle 320. One end of the sliding buckle 3201 is embedded in the longitudinal slide groove 2104 and the other end is connected to the bottom wind baffle 40.

[0042] It should be noted that, as Figure 9 , 10 As shown, through the engagement of the sliding buckle 3201 with the longitudinal groove 2104, when the arc-shaped baffle assembly 30 rotates, the sliding buckle 3201 slides relative to the longitudinal groove 2104, thereby driving the bottom baffle 40 to rotate synchronously. This linkage structure only requires one drive source (driving the arc-shaped baffle assembly 30) to control the two baffles simultaneously, reducing the number of drive mechanisms, simplifying the control system, and reducing costs and failure rates. Moreover, the arc-shaped baffle assembly 30 and the bottom baffle 40 each have different rotation centers, and the sliding connection mechanism can effectively compensate for the relative displacement and angle changes generated during their movement. The sliding degree of freedom of the sliding buckle 3201 in the longitudinal groove 2104 allows the two baffles to adaptively adjust along the groove direction when rotating, avoiding motion interference or structural damage that may be caused by rigid connection.

[0043] It should be noted that the sliding buckle 3201 and the longitudinal slide groove 2104 are connected by an embedded type. During assembly, they can be simply slid in without the need for additional fasteners, which is highly efficient. They can also be quickly disassembled for maintenance, making it convenient for repairs. By adjusting the rotation angle of the central arc-shaped baffle assembly 30, the opening of the bottom baffle 40 to the lower air outlet 120 can be changed, thereby realizing continuous adjustment of the air volume ratio between the side air outlet and the lower air outlet. Users can flexibly allocate the air volume of the side air outlet and the lower air outlet according to actual needs (such as room layout, temperature distribution, usage scenario, etc.) to achieve the best comfort effect.

[0044] In some embodiments, at least one sliding connection mechanism is a plurality of sliding connection mechanisms, which are arranged at intervals along the length direction of the arc-shaped windbreak 320.

[0045] It should be noted that multiple sliding connection mechanisms are arranged at intervals along the length of the central arc-shaped wind deflector 320, expanding the connection point between the bottom wind deflector 40 and the central arc-shaped wind deflector 320 from a single point to multiple points. This effectively prevents the bottom wind deflector 40 from tilting or twisting during movement, improving the stability and reliability of the linkage transmission. Furthermore, the multi-point support structure distributes the driving force and load to multiple connection points, achieving balanced force distribution, avoiding stress concentration at a single point, and extending the service life of the sliding connection mechanism and the bottom wind deflector 40. At the same time, the bottom wind deflector 40 obtains multiple support points along its length, significantly improving its overall rigidity and bending strength, making it less prone to deformation when subjected to airflow impact, and ensuring a tight seal with the lower air outlet 120.

[0046] It should be noted that when the lower air outlet 120 is closed, the multi-point support allows the bottom baffle plate 40 to be evenly pressed against the edge of the lower air outlet 120, avoiding the situation where one side is pressed and the other side is lifted due to single-point drive, which significantly improves the sealing effect and reduces air leakage.

[0047] In some embodiments, the air outlet structure of the ducted air conditioner further includes a lower sealing mechanism, which includes a water receiving tray 50 and a lower air guide frame 60. The water receiving tray 50 is disposed below the evaporator 80 of the ducted air conditioner and is located inside the lower air outlet 120. The lower air guide frame 60 is disposed between the lower air outlet 120 and the water receiving tray 50 and has an air guiding slope. One end of the air guiding slope is connected to the tail end of the water receiving tray 50, and the other end of the air guiding slope is connected to the top of the inner side of the lower air outlet 120. When the arc-shaped baffle assembly 30 is rotated to drive the bottom baffle plate 40 to rotate and block the lower air outlet 120, the arc-shaped baffle plate 320 abuts against the air guiding slope.

[0048] It should be noted that the lower air guide frame 60 is located between the lower air outlet 120 and the water collection tray 50. One end of the air guide slope is connected to the tail end of the water collection tray 50, and the other end is connected to the top of the inner side of the lower air outlet 120. This makes full use of the transition space, resulting in a compact structure that organically connects the water collection tray 50, the lower air guide frame 60, and the lower air outlet 120. Furthermore, the lower air guide frame 60, as a connector, enhances the structural connection strength between the water collection tray 50 and the air outlet housing 10, thereby improving the overall structural stability and vibration resistance.

[0049] It should be noted that in the downward air outlet mode, the guide slope can smoothly guide the airflow to the downward air outlet 120, reducing energy loss and eddy current generation, improving air supply efficiency, and avoiding airflow noise caused by steps or sharp angle structures. In the side air outlet mode, the mid-arc baffle 320 abuts against the guide slope, cutting off the path of airflow leakage from the downward air outlet 120. Furthermore, one end of the guide slope is connected to the tail end of the water collection tray 50, allowing condensate to flow smoothly into the water collection tray 50 (the water collection tray 50 can be shortened), preventing condensate from accumulating near the downward air outlet 120 or being carried into the air outlet channel by the airflow, thus preventing water blowing. At the same time, the guide slope can guide any splashed condensate back to the water collection tray 50, preventing condensate from accumulating on the sealing mating surface and ensuring the long-term reliability of the sealing structure.

[0050] In some embodiments, the air outlet structure of the ducted air conditioner further includes an upper sealing mechanism, which includes an evaporator side plate 70, a first upper baffle protrusion 2101, and a second upper baffle protrusion 2102. The evaporator side plate 70 is connected to the evaporator 80 of the ducted air conditioner and is located above the inner side of the side air outlet 110. It has a first sealing protrusion 710 located near the evaporator 80 and a second sealing protrusion 720 located away from the evaporator 80. The first upper baffle protrusion 2101 is located on the upper... The arc-shaped baffle 210 is located at the end away from the side air outlet 110 and protrudes upward to the outer side of the arc-shaped baffle 210; the second upper baffle protrusion 2102 is located at the end of the upper arc-shaped baffle 210 near the side air outlet 110 and protrudes upward to the outer side of the arc-shaped baffle 210; when the upper arc-shaped baffle assembly 20 is rotated to open the upper air outlet area, the first upper baffle protrusion 2101 abuts against the first sealing protrusion 710, and the second upper baffle protrusion 2102 abuts against the second sealing protrusion 720.

[0051] It should be noted that, as Figure 4 , 5 As shown in Figures 6 and 7, in the side-outlet mode or the dual-outlet mode, the first upper baffle protrusion 2101 and the second upper baffle protrusion 2102 at both ends of the upper arc-shaped baffle 210 abut against the first sealing protrusion 710 and the second sealing protrusion 720 on the evaporator side plate 70, respectively, forming two sealing structures. This effectively prevents airflow from leaking from the gap between the upper arc-shaped baffle 210 and the evaporator side plate 70, ensuring that all airflow is discharged from the upper air outlet area and improving air supply efficiency.

[0052] It should be noted that the upper sealing mechanism has sealing mating points at one end near the evaporator 80 and the other end near the side air outlet 110, forming a multi-point sealing structure. Even if one sealing point experiences slight wear, the other sealing points can still maintain the sealing effect, improving the redundancy and reliability of the sealing system. At the same time, the sealing protrusion and the baffle protrusion automatically form a seal when the baffle plate reaches the predetermined opening position, without the need for an additional pressing mechanism. The structure is simple, the sealing is reliable, and dynamic sealing is achieved in the rotating state. Furthermore, the evaporator side plate 70, while serving the function of evaporator 80 installation and positioning, directly integrates the sealing protrusion, integrating the sealing function into the existing structure without the need for additional sealing components, simplifying the structural design and reducing the number of parts.

[0053] In some embodiments, the upper sealing mechanism further includes a third sealing protrusion 730 and an inner protrusion 2103 of the upper baffle; the third sealing protrusion 730 is disposed between the first sealing protrusion 710 and the second sealing protrusion 720; the inner protrusion 2103 of the upper baffle is disposed on the inner side of one end of the upper arc-shaped baffle 210 near the side air outlet 110; when the upper arc-shaped baffle assembly 20 is rotated to shield the upper air outlet area, the first upper baffle protrusion 2101 abuts against the third sealing protrusion 730, and the inner protrusion 2103 of the upper baffle abuts against the upper edge of the lower baffle support assembly.

[0054] It should be noted that when the upper air outlet is closed, the first upper baffle protrusion 2101 and the third sealing protrusion 730 abut to form the first seal, and the inner side protrusion 2103 of the upper baffle abuts to form the second seal with the upper edge of the lower baffle bracket assembly. The double sealing structure effectively prevents airflow from leaking from the upper air outlet and ensures that all airflow is discharged from the lower air outlet 120 in the lower air outlet mode, thereby improving air supply efficiency.

[0055] It should be noted that the first upper baffle protrusion 2101 moves between the first sealing protrusion 710 and the third sealing protrusion 730. The first sealing protrusion 710 and the third sealing protrusion 730 together constitute the movement limit of the first upper baffle protrusion 2101, which respectively limits the extreme positions of the upper arc-shaped wind deflector 210 when it is opened and closed, realizing bidirectional mechanical limit and avoiding excessive rotation of the wind deflector, which may cause structural damage or sealing failure. Both extreme positions can provide clear position feedback signals to the control system, which facilitates precise position control. In addition, the inner protrusion 2103 of the upper baffle abuts against the upper edge of the lower baffle bracket assembly, using the existing structure as the sealing mating surface, without the need to add additional seals.

[0056] Secondly, embodiments of this application provide a duct air handling unit, including: Such as the air outlet structure of the ducted air conditioner in any of the first aspects; Two drive motors are connected to the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, respectively.

[0057] It should be noted that the two drive motors independently drive the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, respectively, to achieve completely independent control of the upper air outlet zone and the lower air outlet zone / lower air outlet 120. The two do not interfere with each other and their opening can be adjusted independently according to actual needs. Moreover, the two baffle assemblies can be independently controlled, and in addition to the conventional air supply mode, more intermediate state combinations can be achieved (such as upper air outlet zone half open + lower air outlet 120 half open, upper air outlet zone fully open + lower air outlet 120 half open, etc.), to meet the refined air supply needs in different usage scenarios. It should be noted that the two motors are controlled independently, and the rotation angles of the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly can be precisely adjusted respectively, so as to achieve independent and precise adjustment of the air volume ratio between the side air outlet and the bottom air outlet. Each motor can be independently equipped with a position sensor to achieve closed-loop control of the position of its respective baffle assembly, resulting in higher control precision and more accurate repeatability.

[0058] It should be noted that the air outlet structure of the ducted air conditioner includes: an air outlet housing 10, having a side air outlet 110 located on the side and a bottom air outlet 120 located on the bottom; an upper arc-shaped baffle assembly 20, rotatably disposed inside the side air outlet 110, used to open or cover the upper air outlet area of ​​the side air outlet 110; and a lower baffle bracket assembly, rotatably disposed inside the side air outlet 110, used to open the lower air outlet area of ​​the side air outlet 110 and cover the lower air outlet 120. In the side air outlet remote air delivery mode, rotating the lower baffle bracket assembly covers the lower air outlet 120, and rotating the upper arc-shaped baffle assembly 20 partially or completely covers the upper air outlet area, thereby reducing the air outlet area of ​​the side air outlet 110 and increasing the air delivery distance.

[0059] It should be noted that in the side-discharge far-reaching air supply mode, by rotating the lower baffle bracket assembly to block the lower air outlet 120, and simultaneously rotating and adjusting the upper arc-shaped baffle assembly 20 to block the area of ​​the upper air outlet area of ​​the side air outlet 110, the overall air outlet area of ​​the side air outlet 110 is reduced. According to the principles of fluid mechanics, reducing the air outlet area can increase the air outlet velocity, thereby increasing the air supply distance, enabling the airflow to be effectively delivered to the far areas of the room, improving the room heating effect, and reducing the indoor temperature difference.

[0060] It should be noted that when adding dual-outlet functionality, existing technologies often significantly impact the airflow and noise of the side outlet due to the added structure. This solution, through a rotating baffle structure, achieves multi-mode switching while maintaining the integrity of the main structure of the side outlet 110. Furthermore, it optimizes air delivery performance by adjusting the air outlet area, rather than simply adding a blocking structure. This allows for functional expansion while maintaining or improving the side outlet performance. By rotating and adjusting the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, flexible switching between various air delivery modes, such as side outlet remote air delivery, conventional side outlet, and bottom outlet, can be achieved to meet the needs of different usage scenarios.

[0061] In some embodiments, the upper arc-shaped baffle assembly 20 includes an upper arc-shaped baffle 210 and an upper baffle bracket 220. The upper arc-shaped baffle 210 has a convex arc surface in the direction of the side air outlet 110. One end of the upper baffle bracket 220 near the side air outlet 110 is connected to the inner side surface of the upper arc-shaped baffle 210, and the other end away from the side air outlet 110 is rotatably connected to the air outlet housing 10.

[0062] It should be noted that the upper arc-shaped wind deflector 210 has a convex arc surface in the direction of the side air outlet 110. The convex arc surface (the back is a concave arc surface) structure has better aerodynamic characteristics than a flat or concave surface. When the airflow passes through the convex arc surface, it can smoothly turn along the arc surface, reduce airflow separation and vortex generation, thereby reducing wind resistance and airflow noise and improving air supply efficiency.

[0063] It should be noted that, as Figure 7 , 8 As shown in Figures 9 and 10, the end of the upper wind deflector bracket 220 near the side air outlet 110 is connected to the inner side of the upper arc-shaped wind deflector 210, and the end away from the side air outlet 110 is rotatably connected to the air outlet housing 10. This connection method allows the upper arc-shaped wind deflector 210 to be angled around the rotation axis, thereby precisely controlling the shielding area of ​​the upper air outlet area and flexibly adjusting the air outlet area of ​​the side air outlet 110, thereby adjusting the air outlet speed and air delivery distance. The upper wind deflector bracket 220 can be multiple (such as 2, 4, 6, etc.) rods intersecting in the air outlet housing 10. The rod bracket has a small obstruction area for airflow, and airflow can pass smoothly through the gaps between the rods, reducing airflow turbulence and eddies, reducing wind resistance and airflow noise, and improving air delivery efficiency.

[0064] In some embodiments, the lower baffle bracket assembly includes a central arc-shaped baffle assembly 30 and a bottom baffle plate 40. The central arc-shaped baffle assembly 30 is rotatably disposed inside the side air outlet 110, and is used to open or cover the upper area of ​​the lower air outlet area and the inner air outlet area of ​​the lower air outlet 120. One end of the bottom baffle plate 40 is rotatably disposed between the side air outlet 110 and the lower air outlet 120, and the other end is slidably connected to the outer surface of the central arc-shaped baffle assembly 30, and is used to open or cover the lower area of ​​the lower air outlet area and the outer air outlet area of ​​the lower air outlet 120. In the side air outlet mode, rotating the upper arc-shaped baffle assembly 20 opens the upper air outlet area, and rotating the central arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, covering the lower air outlet 120. In the lower air outlet mode, rotating the upper arc-shaped baffle assembly 20 covers the upper air outlet area, and rotating the central arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, covering the lower air outlet area.

[0065] It should be noted that, as Figure 2 , 3As shown in Figures 4, 5, 6, and 7, through the independent control and coordinated operation of the upper arc-shaped baffle assembly 20 and the lower baffle bracket assembly, the following can be achieved: 1) Side air outlet mode: The upper arc-shaped baffle assembly 20 opens the upper air outlet area, and the middle arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet 120, and all airflow is discharged from the side air outlet 110; 2) Lower air outlet mode: The upper arc-shaped baffle assembly 20 blocks the upper air outlet area, and the middle arc-shaped baffle assembly 30 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet 120, and all airflow is discharged from the side air outlet 110; 0 drives the bottom baffle plate 40 to rotate, blocking the lower air outlet area, and all airflow is discharged from the lower air outlet 120; 3) Dual air outlet mode: the upper arc baffle assembly 20 opens the upper air outlet area, and the middle arc baffle assembly 30 drives the bottom baffle plate 40 to rotate, opening the lower air outlet 120, and airflow is discharged from both the side air outlet 110 and the lower air outlet 120 at the same time; the three modes switch smoothly and do not interfere with each other, which can meet the diverse air supply needs of different seasons and different scenarios.

[0066] It should be noted that the lower baffle bracket assembly divides the lower air outlet area into an upper and a lower region: the middle arc-shaped baffle assembly 30 controls the upper region of the lower air outlet area and the inner air outlet area of ​​the lower air outlet 120; the bottom baffle plate 40 controls the lower region of the lower air outlet area and the outer air outlet area of ​​the lower air outlet 120. Through zone control, the air outlet area of ​​the lower air outlet area can be finely adjusted, thereby flexibly controlling the air outlet speed and airflow distribution. Furthermore, if zone control is not used, a large baffle plate would be required to simultaneously shield both the lower air outlet area (which has a large area) and the lower air outlet 120 (which is located in a dispersed manner). The baffle assembly covers the entire area, while through zone control, the middle arc-shaped baffle assembly 30 is only responsible for shielding the upper area of ​​the lower air outlet zone and the inner air outlet zone of the lower air outlet 120; the bottom baffle 40 is only responsible for shielding the lower area of ​​the lower air outlet zone and the outer air outlet zone of the lower air outlet 120. Each baffle only needs to cover its corresponding zone area, and the area of ​​a single baffle is significantly reduced, so that the baffle assembly is decomposed from a large and complex structure into two small and simple structures, making the shape of each baffle more regular, the structure simpler, and the overall volume smaller, which is conducive to the miniaturization and weight reduction of the entire duct air conditioner.

[0067] It should be noted that one end of the bottom baffle 40 is slidably connected to the outer side of the middle arc-shaped baffle assembly 30, forming a linkage transmission structure. Only one drive source is needed to control both baffles simultaneously, simplifying the drive mechanism and reducing costs and failure rates. The rotation centers of the middle arc-shaped baffle assembly 30 and the upper arc-shaped baffle assembly 20 do not coincide, allowing them to rotate and be controlled independently without interference. This avoids motion interference or mutual constraints that may occur due to the coincidence of rotation centers, resulting in simple control logic and clear motion trajectories. The two rotation centers can be selected at their optimal positions according to the internal space structure of the air outlet housing 10. The staggered layout allows each baffle assembly to occupy a different space area during rotation, making full use of the scattered space inside the housing and facilitating the miniaturization of the entire unit. Furthermore, since the two baffle assemblies can be adjusted independently, various air supply modes such as side air outlet mode, side air outlet far-reaching air supply mode, bottom air outlet mode, and dual air outlet mode can be freely combined to meet the diverse needs of different usage scenarios.

[0068] In some embodiments, the central arc-shaped baffle assembly 30 includes a central arc-shaped baffle 320 and a central baffle bracket 310; the central arc-shaped baffle 320 has a concave arc surface in the direction of the side air outlet 110; one end of the central baffle bracket 310 near the side air outlet 110 is connected to the inner side surface of the central arc-shaped baffle 320, and the other end away from the side air outlet 110 is rotatably connected to the air outlet housing 10.

[0069] It should be noted that, as Figure 4 As shown, when the side air outlet mode is activated and the upper air outlet area is open, the central arc-shaped baffle assembly 30 shields the lower air outlet area. At this time, the concave arc surface is opposite to or tangential to the main airflow direction, allowing the airflow to flow smoothly along the concave arc surface, avoiding the formation of right-angle obstructions or vortex areas. This effectively reduces wind resistance and airflow noise, ensuring the efficiency and comfort of the side air outlet. Furthermore, the concave arc surface structure has higher bending stiffness than a flat surface, effectively resisting airflow impact and deformation during long-term use, ensuring the shielding accuracy and sealing effect of the lower air outlet area, and improving the reliability and lifespan of the assembly.

[0070] It should be noted that the middle baffle bracket 310 can be multiple (such as 2, 4, 6, etc.) rods intersecting within the air outlet housing 10. The rod bracket has a small obstruction area for airflow, allowing airflow to pass smoothly through the gaps between the rods, reducing airflow turbulence and eddies, lowering wind resistance and airflow noise, and improving air delivery efficiency.

[0071] It should be noted that, as Figure 2 , 3As shown, in the downward air outlet mode: the upper arc-shaped baffle assembly 20 shields the upper air outlet area, the middle arc-shaped baffle assembly 30 shields the lower air outlet area, and the bottom baffle 40 opens the lower air outlet 120. At this time, although both the convex and concave arc surfaces are shielded, they together form a continuous airflow turning channel: the convex arc surface smoothly guides the airflow impacting it downwards, and the concave arc surface receives the airflow from above, further collects and turns it. The airflow flows smoothly through the bottom baffle 40 to the bottom lower air outlet 120, which can reduce the energy loss and vortex generation of the airflow during the turning process and improve the air supply efficiency of the downward air outlet mode.

[0072] In some embodiments, the air outlet structure of the duct unit further includes at least one sliding connection mechanism, which includes a longitudinal slide groove 2104 and a sliding buckle 3201. The longitudinal slide groove 2104 is provided on the outer side of the arc-shaped wind baffle 320 and extends along the width direction of the arc-shaped wind baffle 320. One end of the sliding buckle 3201 is embedded in the longitudinal slide groove 2104 and the other end is connected to the bottom wind baffle 40.

[0073] It should be noted that, as Figure 9 , 10 As shown, through the engagement of the sliding buckle 3201 with the longitudinal groove 2104, when the arc-shaped baffle assembly 30 rotates, the sliding buckle 3201 slides relative to the longitudinal groove 2104, thereby driving the bottom baffle 40 to rotate synchronously. This linkage structure only requires one drive source (driving the arc-shaped baffle assembly 30) to control the two baffles simultaneously, reducing the number of drive mechanisms, simplifying the control system, and reducing costs and failure rates. Moreover, the arc-shaped baffle assembly 30 and the bottom baffle 40 each have different rotation centers, and the sliding connection mechanism can effectively compensate for the relative displacement and angle changes generated during their movement. The sliding degree of freedom of the sliding buckle 3201 in the longitudinal groove 2104 allows the two baffles to adaptively adjust along the groove direction when rotating, avoiding motion interference or structural damage that may be caused by rigid connection.

[0074] It should be noted that the sliding buckle 3201 and the longitudinal slide groove 2104 are connected by an embedded type. During assembly, they can be simply slid in without the need for additional fasteners, which is highly efficient. They can also be quickly disassembled for maintenance, making it convenient for repairs. By adjusting the rotation angle of the central arc-shaped baffle assembly 30, the opening of the bottom baffle 40 to the lower air outlet 120 can be changed, thereby realizing continuous adjustment of the air volume ratio between the side air outlet and the lower air outlet. Users can flexibly allocate the air volume of the side air outlet and the lower air outlet according to actual needs (such as room layout, temperature distribution, usage scenario, etc.) to achieve the best comfort effect.

[0075] In some embodiments, at least one sliding connection mechanism is a plurality of sliding connection mechanisms, which are arranged at intervals along the length direction of the arc-shaped windbreak 320.

[0076] It should be noted that multiple sliding connection mechanisms are arranged at intervals along the length of the central arc-shaped wind deflector 320, expanding the connection point between the bottom wind deflector 40 and the central arc-shaped wind deflector 320 from a single point to multiple points. This effectively prevents the bottom wind deflector 40 from tilting or twisting during movement, improving the stability and reliability of the linkage transmission. Furthermore, the multi-point support structure distributes the driving force and load to multiple connection points, achieving balanced force distribution, avoiding stress concentration at a single point, and extending the service life of the sliding connection mechanism and the bottom wind deflector 40. At the same time, the bottom wind deflector 40 obtains multiple support points along its length, significantly improving its overall rigidity and bending strength, making it less prone to deformation when subjected to airflow impact, and ensuring a tight seal with the lower air outlet 120.

[0077] It should be noted that when the lower air outlet 120 is closed, the multi-point support allows the bottom baffle plate 40 to be evenly pressed against the edge of the lower air outlet 120, avoiding the situation where one side is pressed and the other side is lifted due to single-point drive, which significantly improves the sealing effect and reduces air leakage.

[0078] In some embodiments, the air outlet structure of the ducted air conditioner further includes a lower sealing mechanism, which includes a water receiving tray 50 and a lower air guide frame 60. The water receiving tray 50 is disposed below the evaporator 80 of the ducted air conditioner and is located inside the lower air outlet 120. The lower air guide frame 60 is disposed between the lower air outlet 120 and the water receiving tray 50 and has an air guiding slope. One end of the air guiding slope is connected to the tail end of the water receiving tray 50, and the other end of the air guiding slope is connected to the top of the inner side of the lower air outlet 120. When the arc-shaped baffle assembly 30 is rotated to drive the bottom baffle plate 40 to rotate and block the lower air outlet 120, the arc-shaped baffle plate 320 abuts against the air guiding slope.

[0079] It should be noted that the lower air guide frame 60 is located between the lower air outlet 120 and the water collection tray 50. One end of the air guide slope is connected to the tail end of the water collection tray 50, and the other end is connected to the top of the inner side of the lower air outlet 120. This makes full use of the transition space, resulting in a compact structure that organically connects the water collection tray 50, the lower air guide frame 60, and the lower air outlet 120. Furthermore, the lower air guide frame 60, as a connector, enhances the structural connection strength between the water collection tray 50 and the air outlet housing 10, thereby improving the overall structural stability and vibration resistance.

[0080] It should be noted that in the downward air outlet mode, the guide slope can smoothly guide the airflow to the downward air outlet 120, reducing energy loss and eddy current generation, improving air supply efficiency, and avoiding airflow noise caused by steps or sharp angle structures. In the side air outlet mode, the mid-arc baffle 320 abuts against the guide slope, cutting off the path of airflow leakage from the downward air outlet 120. Furthermore, one end of the guide slope is connected to the tail end of the water collection tray 50, allowing condensate to flow smoothly into the water collection tray 50 (the water collection tray 50 can be shortened), preventing condensate from accumulating near the downward air outlet 120 or being carried into the air outlet channel by the airflow, thus preventing water blowing. At the same time, the guide slope can guide any splashed condensate back to the water collection tray 50, preventing condensate from accumulating on the sealing mating surface and ensuring the long-term reliability of the sealing structure.

[0081] In some embodiments, the air outlet structure of the ducted air conditioner further includes an upper sealing mechanism, which includes an evaporator side plate 70, a first upper baffle protrusion 2101, and a second upper baffle protrusion 2102. The evaporator side plate 70 is connected to the evaporator 80 of the ducted air conditioner and is located above the inner side of the side air outlet 110. It has a first sealing protrusion 710 located near the evaporator 80 and a second sealing protrusion 720 located away from the evaporator 80. The first upper baffle protrusion 2101 is located on the upper... The arc-shaped baffle 210 is located at the end away from the side air outlet 110 and protrudes upward to the outer side of the arc-shaped baffle 210; the second upper baffle protrusion 2102 is located at the end of the upper arc-shaped baffle 210 near the side air outlet 110 and protrudes upward to the outer side of the arc-shaped baffle 210; when the upper arc-shaped baffle assembly 20 is rotated to open the upper air outlet area, the first upper baffle protrusion 2101 abuts against the first sealing protrusion 710, and the second upper baffle protrusion 2102 abuts against the second sealing protrusion 720.

[0082] It should be noted that, as Figure 4 , 5 As shown in Figures 6 and 7, in the side-outlet mode or the dual-outlet mode, the first upper baffle protrusion 2101 and the second upper baffle protrusion 2102 at both ends of the upper arc-shaped baffle 210 abut against the first sealing protrusion 710 and the second sealing protrusion 720 on the evaporator side plate 70, respectively, forming two sealing structures. This effectively prevents airflow from leaking from the gap between the upper arc-shaped baffle 210 and the evaporator side plate 70, ensuring that all airflow is discharged from the upper air outlet area and improving air supply efficiency.

[0083] It should be noted that the upper sealing mechanism has sealing mating points at one end near the evaporator 80 and the other end near the side air outlet 110, forming a multi-point sealing structure. Even if one sealing point experiences slight wear, the other sealing points can still maintain the sealing effect, improving the redundancy and reliability of the sealing system. At the same time, the sealing protrusion and the baffle protrusion automatically form a seal when the baffle plate reaches the predetermined opening position, without the need for an additional pressing mechanism. The structure is simple, the sealing is reliable, and dynamic sealing is achieved in the rotating state. Furthermore, the evaporator side plate 70, while serving the function of evaporator 80 installation and positioning, directly integrates the sealing protrusion, integrating the sealing function into the existing structure without the need for additional sealing components, simplifying the structural design and reducing the number of parts.

[0084] In some embodiments, the upper sealing mechanism further includes a third sealing protrusion 730 and an inner protrusion 2103 of the upper baffle; the third sealing protrusion 730 is disposed between the first sealing protrusion 710 and the second sealing protrusion 720; the inner protrusion 2103 of the upper baffle is disposed on the inner side of one end of the upper arc-shaped baffle 210 near the side air outlet 110; when the upper arc-shaped baffle assembly 20 is rotated to shield the upper air outlet area, the first upper baffle protrusion 2101 abuts against the third sealing protrusion 730, and the inner protrusion 2103 of the upper baffle abuts against the upper edge of the lower baffle support assembly.

[0085] It should be noted that when the upper air outlet is closed, the first upper baffle protrusion 2101 and the third sealing protrusion 730 abut to form the first seal, and the inner side protrusion 2103 of the upper baffle abuts to form the second seal with the upper edge of the lower baffle bracket assembly. The double sealing structure effectively prevents airflow from leaking from the upper air outlet and ensures that all airflow is discharged from the lower air outlet 120 in the lower air outlet mode, thereby improving air supply efficiency.

[0086] It should be noted that the first upper baffle protrusion 2101 moves between the first sealing protrusion 710 and the third sealing protrusion 730. The first sealing protrusion 710 and the third sealing protrusion 730 together constitute the movement limit of the first upper baffle protrusion 2101, which respectively limits the extreme positions of the upper arc-shaped wind deflector 210 when it is opened and closed, realizing bidirectional mechanical limit and avoiding excessive rotation of the wind deflector, which may cause structural damage or sealing failure. Both extreme positions can provide clear position feedback signals to the control system, which facilitates precise position control. In addition, the inner protrusion 2103 of the upper baffle abuts against the upper edge of the lower baffle bracket assembly, using the existing structure as the sealing mating surface, without the need to add additional seals.

[0087] Thirdly, such as Figure 11 , 12 As shown, this application provides a method for controlling the air outlet of a ducted air conditioner, applied to a ducted air conditioner as described in any embodiment of the second aspect, comprising: S101: Obtain the current mode command of the duct unit; S102: If the current mode command is cooling mode, rotate the upper arc-shaped baffle assembly 20 to open the upper air outlet area, and rotate the middle arc-shaped baffle assembly 30 to drive the bottom baffle 40 to rotate and block the lower air outlet 120 and open the lower air outlet area.

[0088] It should be noted that in cooling mode, the upper arc-shaped baffle assembly 20 opens the upper air outlet area, while the middle arc-shaped baffle assembly 30 drives the bottom baffle 40 to block the lower air outlet 120 and open the lower air outlet area. This allows cold air to be sent out from the upper and lower areas of the side air outlet 110 simultaneously, resulting in a uniform distribution of cold air and preventing excessive concentration in the lower part of the room. This achieves rapid cooling and uniform refrigeration. Furthermore, the cold air naturally sinks after being sent out from the side air outlet 110, forming a natural convection circulation with the indoor hot air, enhancing the airflow and temperature uniformity of the indoor air and improving the comfort of cooling.

[0089] In some embodiments, the instruction to obtain the current mode of the duct unit further includes: If the current mode command is heating mode, then rotate the upper arc-shaped baffle assembly 20 to shield the upper air outlet area, and rotate the middle arc-shaped baffle assembly 30 to drive the bottom baffle 40 to rotate and open the lower air outlet 120 and shield the lower air outlet area.

[0090] It should be noted that in heating mode, the upper arc-shaped baffle assembly 20 is controlled to shield the upper air outlet area, while the middle arc-shaped baffle assembly 30 is controlled to drive the bottom baffle plate 40 to open the lower air outlet 120 and shield the lower air outlet area. This allows hot air to be concentrated and delivered from the lower air outlet 120 at the bottom. The hot air rises naturally and forms a natural convection circulation with the indoor cold air, enhancing the airflow and temperature uniformity of the indoor air. By closing the side air outlet 110 (shielding the upper and lower air outlet areas), all the hot air is forced to be concentrated and discharged from the lower air outlet 120. The air outlet area is reduced and the air outlet speed is increased, allowing the hot air to be pushed to a more distant area of ​​the room. This effectively improves the problem of limited air delivery distance and poor heating effect in distant areas when the traditional side-outlet duct is heating.

[0091] In some embodiments, the instruction to obtain the current mode of the duct unit further includes: If the current mode command is the dual air outlet mode, then rotate the upper arc-shaped baffle assembly 20 to open the upper air outlet area, and rotate the middle arc-shaped baffle assembly 30 to drive the bottom baffle plate 40 to rotate and block part of the lower air outlet 120 and part of the lower air outlet area; If the current mode command is the side-outlet remote air supply mode, then rotate the upper arc-shaped baffle assembly 20 to open part of the upper air outlet area, and rotate the middle arc-shaped baffle assembly 30 to drive the bottom wind deflector 40 to rotate and cover the lower air outlet 120.

[0092] It should be noted that in dual-outlet mode, the upper air outlet is open, part of the lower air outlet 120 is open, and part of the lower air outlet area is blocked, allowing airflow to be discharged simultaneously from the upper part of the side air outlet 110 and the lower air outlet 120. This combines the advantages of long air delivery distance of side air outlets and wide coverage of lower air outlets, making it suitable for scenarios that require rapid and uniform temperature adjustment. By controlling the arc-shaped baffle assembly 30 to block part of the lower air outlet 120 and part of the lower air outlet area, flexible distribution of airflow between the side and lower air outlets can be achieved. Users can select an appropriate airflow ratio based on factors such as room layout and temperature distribution (e.g., ...). Figure 5 , 6 As shown in Figure 7, as a° increases, the lower air outlet 120 will gradually decrease, and the side air outlet 110 will gradually increase. Adjusting a° so that H1 = H2 + A, at this time the side air outlet equals the lower air outlet. The specific value may fluctuate due to losses. Therefore, a constant A is proposed, which can be 0.1-0.2H2). By partially shielding the lower air outlet area, the mutual interference of airflow between the side air outlet and the lower air outlet can be reduced, so that the two air outlet methods can work together and improve the overall air supply efficiency.

[0093] It should be noted that in the side-discharge far-reaching air delivery mode, the upper arc-shaped baffle assembly 20 partially opens the upper air outlet area, reducing the air outlet area of ​​the side air outlet 110. This increases the air outlet velocity, extends the air delivery distance, and effectively delivers airflow to the far end of the room. The side-discharge far-reaching air delivery mode is suitable for heating scenarios. Hot air is concentrated and delivered from the side air outlet 110, then pushed to the far end of the room and rises naturally, effectively improving the poor heating effect in the far end of the room when using traditional side-discharge duct systems. Furthermore, by continuously adjusting the rotation angle of the upper arc-shaped baffle assembly 20 (e.g., ...), the air delivery can be further enhanced. Figure 1 As shown, the height of the side air outlet is H3, and the horizontal angle is b°. The height of the air outlet is changed to H3 by adjusting b° (the angle b is 30-60°). The air outlet speed and air delivery distance can be steplessly adjusted, and users can choose the most suitable air delivery distance according to the room size and layout.

[0094] It should be noted that by combining cooling mode, heating mode, dual air outlet mode, and side air outlet remote air supply mode, air supply control covering all operating conditions is achieved, meeting the diverse air supply requirements under different seasons, different scenarios, and different user needs; smooth switching between modes can be achieved by continuously adjusting the position of the baffle, avoiding sudden changes in air volume or airflow turbulence during mode switching, thus improving the user experience; the baffle action is automatically controlled by mode commands, eliminating the need for manual adjustment, thereby improving the intelligence level and ease of use of the duct air conditioner.
