Description

Technical Field

[0001] This application relates to the field of air handling equipment, and more particularly to indoor units and air handling equipment. Background Technology

[0002] Air handling units typically include an air outlet and a deflector plate and deflector blades installed at the outlet. The deflector plate is movably installed at the air outlet, and its position can be adjusted to change the opening state of the air outlet, thereby controlling the airflow direction. The air delivery path can be further optimized by adjusting the blade angle.

[0003] However, the existing indoor unit's air guiding structure mainly adjusts the airflow direction by rotating or oscillating the air guide blades, which has certain limitations when adjusting the air outlet range. Utility Model Content

[0004] This application provides an indoor unit and an air handling equipment to solve the problem of a small air outlet range.

[0005] In a first aspect, this application provides an indoor unit, including a housing, an air guide plate, and an adjustment assembly;

[0006] The housing has an air outlet facing forward;

[0007] The air guide plate is movably disposed on the housing, and the air guide plate can move closer to or further away from the air outlet to close or open the air outlet;

[0008] The adjustment component is movably disposed in the housing, and the adjustment component is connected to the air guide plate. The air guide plate can drive the adjustment component to extend out of and move into the housing through the air outlet.

[0009] By adopting the above technical solution, the indoor unit includes a casing, an air guide plate, and an adjustment component. The movement of the air guide plate causes the adjustment component to extend or retract from the air outlet of the casing, allowing the adjustment component to overcome the limitations of the air outlet position and adjust the air supply within a larger space. Through the coordinated operation of the air guide plate and the adjustment component, the adjustable range of the indoor unit's air supply is effectively expanded, significantly improving the coverage area of ​​the air supply.

[0010] Specifically, the technical solution of this application uses the opening and closing motion of the air guide plate to drive the adjustment component to move, allowing the adjustment component to extend outside the air outlet. When the air guide plate is open, the adjustment component can extend outside the air outlet, significantly expanding the air guiding range; when the air guide plate is closed, the adjustment component can be completely retracted into the housing. This linkage structure not only achieves effective expansion of the air guiding range, but also maintains the simplicity and reliability of the equipment structure.

[0011] In some embodiments of this application, the adjustment assembly includes a transition plate, which is movably disposed in the housing and connected to the air guide plate;

[0012] The adjustment assembly includes a support member, which is rotatably mounted on the transition plate.

[0013] This regulating component achieves two-stage motion control through the linkage between the transition plate and the air guide plate: the transition plate is driven by the air guide plate to extend and retract, while the supporting component can rotate independently relative to the transition plate. This composite regulating mechanism not only expands the range of airflow guidance but also achieves precise multi-angle air delivery by superimposing rotational degrees of freedom, significantly improving the uniformity of airflow distribution and the flexibility of directional control.

[0014] In some embodiments of this application, the air guide plate is provided with a connecting component, and the air guide plate is connected to the transition plate through the connecting component;

[0015] When the air guide plate is away from the air outlet, the air guide plate drives the transition plate to extend out of the housing from the air outlet through the connecting assembly; when the air guide plate is close to the air outlet, the air guide plate drives the transition plate to move into the housing through the connecting assembly.

[0016] This connecting component enables synchronized control of the air guide vane and the transition plate, allowing the opening and closing motion of the air guide vane to synchronously drive the extension and retraction of the transition plate. This linkage mechanism ensures coordinated opening and closing of the airflow channel and expands the airflow adjustment range through the extension and retraction of the transition plate, thereby improving air delivery coverage and adjustment accuracy. The overall structure simplifies the drive system and enhances motion synchronization and reliability.

[0017] In some embodiments of this application, the connecting assembly includes a rotating link and a driven link;

[0018] The first end of the rotating connecting rod is rotatably connected to the housing, and the second end of the rotating connecting rod is rotatably connected to the air guide plate. The air guide plate moves closer to or further away from the air outlet through the rotating connecting rod.

[0019] The first end of the driven link is rotatably connected to the rotating link, and the second end of the driven link is rotatably connected to the transition plate.

[0020] This connecting assembly forms a multi-stage linkage mechanism through a rotating link and a driven link: the rotating link converts the opening and closing motion of the air guide plate into rotational motion, while the driven link further transmits this rotational motion to the transition plate, achieving precise linkage control between the air guide plate and the transition plate. This dual-link design allows the transition plate to extend or retract synchronously with the air guide plate, ensuring motion coordination and optimizing force transmission efficiency through the mechanical lever principle, significantly improving the stability and range coverage of airflow regulation.

[0021] In some embodiments of this application, the second end of the rotating connecting rod is provided with an extension rod, and the extension direction of the extension rod is parallel to the length direction of the air guide plate;

[0022] The driven link is located near the center of the air outlet relative to the rotating link, and the driven link is rotatably connected to the extension rod.

[0023] This extension rod structure optimizes the positioning of the driven link's connection point near the center of the air outlet by extending the rotating link's actuating end along the length of the air guide plate. This arrangement significantly improves the force angle of the driven link, allowing the rotational motion of the rotating link to be more efficiently converted into the linear displacement of the transition plate, reducing lateral force loss and improving transmission efficiency. Simultaneously, the parallel arrangement of the extension rod ensures coordination with the air guide plate's movement trajectory, avoiding mechanical interference and enhancing the overall stability and reliability of the movement.

[0024] In some embodiments of this application, the number of the connecting components is two, and the two rotating connecting rods are respectively connected to the ends of the air guide plate;

[0025] The number of adjustment components is two, and each of the transition plates is connected to the rotating link through a driven link.

[0026] This symmetrical double-link structure drives the adjustment components on both sides through two connecting components, forming a balanced force transmission system. Two rotating links are symmetrically arranged at both ends of the air guide plate, each independently controlling the movement of the corresponding transition plate through a driven link, ensuring both synchronous and coordinated movement on both sides, and enabling differentiated airflow adjustment.

[0027] In some embodiments of this application, in the adjustment assembly, one end of the carrier near the edge of the air outlet is rotatably connected to the transition plate;

[0028] One end of the support member near the center of the air outlet can extend out of and move into the housing through the air outlet.

[0029] One end of the support component is fixed to the edge of the air outlet via a transition plate, forming a pivot point for rotation, while the other end extends freely in the center of the air outlet. This asymmetrical layout allows the airflow guide to extend fully outside the air outlet, significantly expanding the airflow adjustment range. When the support component is retracted, it can be compactly stored inside the housing, achieving an optimized balance between adjustment range and space occupation.

[0030] In some embodiments of this application, the adjustment component is provided with a mounting bracket, the mounting bracket is disposed inside the housing, and the mounting bracket is movably connected to the transition plate;

[0031] The mounting bracket is provided with a guide groove, the first end of which faces the front side of the housing and the second end of which faces the rear side of the housing;

[0032] The transition plate is provided with a guide member, which is slidably disposed within the guide groove.

[0033] This adjustment assembly forms a precision sliding pair with the guide groove of the mounting bracket and the guide component of the transition plate, creating a stable directional motion mechanism. The mounting bracket, fixed within the housing, provides a supporting foundation, and its guide groove, running from front to rear, constrains the movement trajectory of the transition plate, allowing it to extend or retract along a predetermined path under the drive of the air guide plate, ensuring the stability and repeatability of the airflow adjustment process. This guiding structure effectively balances the requirements for motion flexibility and mechanical rigidity.

[0034] In some embodiments of this application, the carrier is provided with a plurality of air guide blades, and the air guide blades are rotatably connected to the carrier.

[0035] This support component integrates multiple independently rotatable guide vanes to form a multi-stage airflow regulation system. Each guide vane can be angled based on the extension and retraction movement of the support component, achieving precise control of the airflow. This allows for a wide range of changes in the airflow direction and optimizes the uniformity of airflow distribution through differentiated angle configurations between the vanes. This composite regulation structure significantly improves airflow accuracy and coverage flexibility, meeting diverse environmental requirements.

[0049] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] As described in the background section, air handling equipment, taking the indoor unit as an example, typically has an air deflector and guide vanes at the air outlet. The guide vanes are installed inside the air outlet and adjust the airflow direction through rotation. While this structure can achieve basic airflow direction control, it still has significant shortcomings in practical applications.

[0051] In existing technologies, the adjustment range of the guide vanes is limited by their fixed installation inside the air outlet, resulting in a limited range of air delivery angle adjustment. Because the guide vanes are always located inside the air outlet and their relative position cannot be changed, insufficient airflow coverage is likely to occur during adjustment. Especially when it is necessary to expand the air delivery range, the adjustment capability of traditional structures often fails to meet actual needs.

[0052] To address the aforementioned issues, this application proposes an indoor unit comprising a housing, an air guide plate, and an adjustment component. The movement of the air guide plate causes the adjustment component to extend or retract from the air outlet of the housing, enabling the adjustment component to overcome the limitations of the air outlet position and adjust airflow over a larger spatial range. Through the coordinated operation of the air guide plate and the adjustment component, the adjustable range of the indoor unit's airflow is effectively expanded, significantly increasing the coverage area of ​​the airflow.

[0053] Specifically, the technical solution of this application uses the opening and closing motion of the air guide plate to drive the adjustment component to move, allowing the adjustment component to extend outside the air outlet. When the air guide plate is open, the adjustment component can extend outside the air outlet, significantly expanding the air guiding range; when the air guide plate is closed, the adjustment component can be completely retracted into the housing. This linkage structure not only achieves effective expansion of the air guiding range, but also maintains the simplicity and reliability of the equipment structure.

[0060] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0061] See Figures 1 to 7 This application provides an indoor unit, which may include a housing 100, an air guide plate 200, and an adjustment component 300.

[0062] The housing 100 can serve as the main support structure for the indoor unit and provide an installation base for various functional components. The housing 100 may be provided with an air outlet 110 facing forward, which can serve as a channel for airflow discharge.

[0063] The air guide plate 200 can serve as an airflow control component, opening and closing the air outlet 110 by changing its position, thereby regulating the airflow. Specifically, the air guide plate 200 is movably disposed within the housing 100, and can be moved closer to or further away from the air outlet 110 to close or open the air outlet 110. When close to the air outlet 110, it forms a sealed enclosure; when far from the air outlet 110, it forms an airflow channel.

[0064] There are various ways to connect the air guide plate 200 to the housing 100. For example, the air guide plate 200 can be oscillating by means of a hinge or a pivot.

[0065] The regulating component 300, as an extension mechanism for airflow regulation, can be movably mounted on the housing 100 and can extend or retract at the air outlet 110 of the housing 100. The regulating component 300, extending to the outside of the air outlet 110, can guide the airflow to diffuse to a more distant area, effectively expanding the air supply range.

[0066] The regulating component 300 can be connected to the air guide plate 200. The air guide plate 200 can drive the regulating component 300 to extend and move into the housing 100 through the air outlet 110. When the air guide plate 200 performs an opening or closing action, it can synchronously drive the regulating component 300 to extend or move in, thereby forming a complete airflow channel regulating system.

[0067] Understandably, in the indoor unit, the air outlet 110 of the housing 100 serves as the main channel for airflow exhaust, and its front opening design provides movement space for the air guide mechanism and the adjustment component 300. The movable connection structure of the air guide plate 200 executes a movement trajectory towards or away from the air outlet 110 within the housing 100, and this movement process directly controls the opening and closing state of the air outlet 110. The adjustment component 300, through its connection with the air guide plate 200, converts the movement of the air guide plate 200 into its own extension and retraction actions, thereby forming a complete linkage adjustment system.

[0068] During the specific operation, when the air guide plate 200 performs an opening action away from the air outlet 110, its movement is transmitted to the adjustment component 300, driving the adjustment component 300 to extend outward from the air outlet 110 along a predetermined trajectory. This extension movement causes a portion of the structure of the adjustment component 300 to extend to the outside of the housing 100, forming an extended guide surface, thereby expanding the airflow adjustment range. In this state, the air outlet 110 is fully open, and the airflow can be simultaneously discharged outward through the composite flow channel formed by the air guide plate 200 and the adjustment component 300.

[0069] When the air guide plate 200 performs a closing action near the air outlet 110, it drives the adjusting component 300 to move in the opposite direction along its original trajectory, causing the extended portion to gradually retract into the housing 100. As the air guide plate 200 finally abuts against the edge of the air outlet 110, the adjusting component 300 is completely retracted into the housing 100, and the air outlet 110 reaches a completely closed state. Throughout the entire movement, the displacement of the air guide plate 200 and the adjusting component 300 maintains a definite correspondence, ensuring the synchronicity and coordination of their movements.

[0070] In one possible implementation, the adjustment assembly 300 may include a mounting bracket 310 and a transition plate 320.

[0071] The mounting bracket 310 serves as a support frame for the adjustment assembly 300 and can be housed within the housing 100, providing a stable mounting foundation for the entire adjustment assembly 300.

[0072] The transition plate 320 can serve as an intermediate transmission component connecting the air guide plate 200 and the adjustment assembly 300. It is movably mounted on the mounting bracket 310 and connected to the air guide plate 200. The transition plate 320 can be used to convert the movement of the air guide plate 200 into the extension and retraction of the adjustment assembly 300.

[0073] The regulating component 300 may include a carrier 330. The carrier 330 is rotatably mounted on the transition plate 320 and constitutes the actuating element for airflow regulation. The carrier 330 can extend along the length of the air outlet 110 to cover the entire area of ​​the air outlet 110, ensuring the integrity and consistency of airflow regulation.

[0074] The support member 330 may be provided with multiple air guide vanes 331, and the airflow can be precisely controlled by adjusting the angle of each air guide vane 331 independently. Each air guide vane 331 may be arranged sequentially along the plate surface of the support member 330, and each air guide vane 331 may be rotatably connected to the support member 330.

[0075] It is understandable that the transition plate 320 is moved by the air guide plate 200, which in turn drives the carrier 330 to move. At this time, the position of the carrier 330 relative to the air outlet 110 changes. Furthermore, since the air guide blades 331 are mounted on the carrier 330, each air guide blade 331 on the carrier 330 also moves with the carrier 330. At this time, even if the position of the air guide blades 331 relative to the carrier 330 does not change, the position of the air guide blades 331 relative to the air outlet 110 is changed, which can achieve the effect of adjusting the air delivery angle of the air guiding structure.

[0076] Of course, if the position of the bearing 330 relative to the air outlet 110 changes, and the position of the guide vane 331 also changes relative to the bearing 330, the position change can weaken or even eliminate the limitation on the deflection angle of the guide vane 331.

[0077] In one possible implementation, in the adjustment assembly 300, one end of the support member 330 near the edge of the air outlet 110 can be rotatably connected to the transition plate 320. The end of the support member 330 near the center of the air outlet 110 can extend into and retract into the housing 100 through the air outlet 110.

[0078] The rotating connection near the edge of the air outlet 110 can serve as a fixed fulcrum for the bearing 330, determining the position of the axis of rotation. The movable end near the middle of the air outlet 110 can move freely within the airflow channel.

[0079] As the transition plate 320 moves outward from the air outlet 110, it causes the carrier component 330 to gradually extend out of the housing 100. Simultaneously, the carrier component 330 can rotate around the connection point at the edge of the air outlet 110, adjusting the guide vanes 331 to the optimal working angle. During retraction, the transition plate 320 can cause the carrier component 330 to retract into the housing 100, while simultaneously rotating to its retracted position. This movement mechanism ensures that the carrier component 330 achieves maximum airflow adjustment range in the extended state and is completely concealed within the housing 100 in the retracted state, maintaining the overall aesthetics of the equipment.

[0080] In one possible implementation, the air guide plate 200 may be provided with a connecting component 210. The air guide plate 200 can be connected to the transition plate 320 through the connecting component 210. The connecting component 210 can establish a kinematic coupling relationship between the air guide plate 200 and the transition plate 320, converting the opening and closing action of the air guide plate 200 into the displacement motion of the transition plate 320.

[0081] When the air guide plate 200 is away from the air outlet 110, the air guide plate 200 can drive the transition plate 320 to extend out of the housing 100 from the air outlet 110 via the connecting component 210. This allows the transition plate 320 to extend outward synchronously when the air guide plate 200 opens the air outlet 110, forming an extended airflow guiding structure. During this process, the connecting component 210 can convert the rotational motion of the air guide plate 200 into the linear displacement of the transition plate 320, while ensuring the synchronicity and coordination of the movements of the air guide plate 200 and the transition plate 320. The extension of the transition plate 320 allows the effective working area of ​​the regulating component 300 to extend beyond the boundary of the housing 100, expanding the airflow regulation range.

[0082] When the air guide plate 200 approaches the air outlet 110, the air guide plate 200 can drive the transition plate 320 to move into the housing 100 through the connecting component 210, so that when the air guide plate 200 closes the air outlet 110, the transition plate 320 can synchronously retract into the housing 100 along the original trajectory, keeping in sync with the closing action of the air guide plate 200.

[0083] like Figure 6 As shown, in one possible implementation, the mounting bracket 310 may be provided with a guide groove 311. The guide groove 311 can determine the movement path of the transition plate 320 during extension and retraction.

[0084] The first end of the guide groove 311 can face the front side of the housing 100, and the second end of the guide groove 311 can face the rear side of the housing 100. The first end facing the front side can ensure that the transition plate 320 can reach the predetermined working position when it extends, and the second end facing the rear side can make the retraction movement natural and smooth.

[0085] like Figure 7As shown, the transition plate 320 may be provided with a guide member 321, which can be slidably disposed within the guide groove 311. The guide member 321 is used to constrain the movement of the transition plate 320 on the trajectory defined by the guide groove 311, ensuring that the adjustment component 300 maintains accurate positioning and stable movement posture throughout the entire working stroke.

[0086] There are various ways in which the guide member 321 and the guide groove 311 can cooperate. For example, the cylindrical guide member 321 can form a linear contact with the rectangular guide groove 311, or the slider-shaped guide member 321 can cooperate with the rectangular guide groove 311.

[0087] When the transition plate 320 is driven by the connecting assembly 210, the guide member 321 can slide smoothly along the predetermined trajectory of the guide groove 311, converting the rotary input into linear displacement. Figure 6 As shown, during the extension phase, the guide 321 slides forward from the second end of the guide groove 311 located on the rear side of the housing 100. As the movement progresses, the guide 321 gradually approaches the middle transition area of ​​the guide groove 311. When the guide 321 reaches the first end of the guide groove 311 located on the front side of the housing 100, the transition plate 320 reaches the maximum extension position.

[0088] like Figure 5 As shown, during the retraction phase, the guide 321 slides in the opposite direction along the original trajectory. Starting from the first end of the guide groove 311 located on the front side of the housing 100, the guide 321 moves backward under the pulling force of the driven link 212 until it reaches the second end of the guide groove 311 located on the rear side of the housing 100.

[0089] In one possible implementation, the connecting assembly 210 may include a rotating link 211 and a driven link 212. The rotating link 211 can serve as the active transmission component of the connecting assembly 210, converting the composite motion of the guide vane 200 into a defined rotational motion, and controlling the displacement path of the guide vane 200 through its own swing trajectory. The length and fulcrum position of the rotating link 211 can determine the range of motion and opening / closing angle of the guide vane 200. The driven link 212 can serve as a secondary transmission component of the connecting assembly 210, establishing a motion coupling relationship between the rotating link 211 and the transition plate 320, further converting the swing motion of the rotating link 211 into the linear displacement of the transition plate 320. The proportional length and connection point position of the driven link 212 can determine the displacement and motion characteristics of the transition plate 320.

[0090] The first end of the rotating link 211 can be rotatably connected to the housing 100, and the second end of the rotating link 211 can be rotatably connected to the air guide plate 200. The rotatable connection between the first end of the rotating link 211 and the housing 100 can form a fixed fulcrum for the entire mechanism, and the rotatable connection between the second end of the rotating link 211 and the air guide plate 200 can form a motion transmission node. Through this node, the swing motion of the rotating link 211 is converted into the displacement motion of the air guide plate 200, so that the air guide plate 200 can move closer to or further away from the air outlet 110 along a predetermined path through the rotating link 211, thereby realizing the opening and closing control of the air outlet 110.

[0091] When the rotating link 211 swings around its first fulcrum, its second end can push the air guide plate 200 along a specific trajectory. This trajectory depends on the length of the rotating link 211, the position of the fulcrum, and the arrangement of the connection points of the air guide plate 200. During the opening process of the air guide plate 200 moving away from the air outlet 110, the swinging of the rotating link 211 can drive the air guide plate 200 to move outward. During the closing process of the air guide plate 200 approaching the air outlet 110, the rotating link 211 swings in the opposite direction, which can reset the air guide plate 200 to the closed position.

[0092] The first end of the driven link 212 can be rotatably connected to the rotating link 211, and the second end of the driven link 212 can be rotatably connected to the transition plate 320. The rotatable connection between the first end of the driven link 212 and the rotating link 211 can form an intermediate node for motion transmission, and the rotatable connection between the second end of the driven link 212 and the transition plate 320 can convert the rotational motion of the rotating link 211 into the linear displacement of the transition plate 320, completing the end output of the entire motion transmission chain, so that the transition plate 320 can extend and move into the housing 100 through the air outlet 110.

[0093] When the driven link 212 undergoes planar motion due to the swing of the rotating link 211, the second end of the driven link 212 can drive the transition plate 320 to make linear displacement along the guide structure of the mounting bracket 310. The stroke of this linear motion depends on the connection position between the driven link 212 and the rotating link 211, the length of the driven link 212, and the connection angle with the transition plate 320. During the movement of the transition plate 320 extending out of the housing 100, the driven link 212 causes the transition plate 320 to slide outward of the air outlet 110 through a pulling action; during the resetting process of the transition plate 320 retracting into the housing 100, the driven link 212 switches to a pushing action, driving the transition plate 320 back to the initial position along the original path.

[0094] In one possible implementation, the second end of the rotating link 211 may be provided with an extension rod 213, which can be used to provide an additional connection point for the driven link 212 and optimize the lever arm ratio of force transmission.

[0095] The extension direction of the extension rod 213 can be parallel to the length direction of the air guide plate 200. The extension rod 213 can serve as an extension structure for motion transmission, and its extension characteristic along the length direction of the air guide plate 200 can expand the range of action of the rotating connecting rod 211. The parallel arrangement of the extension rod 213 with the length direction of the air guide plate 200 ensures that its motion trajectory is coordinated with the structural features of the air guide plate 200, avoiding motion interference.

[0096] Driven link 212 is located near the center of the air outlet 110 relative to rotating link 211, and is rotatably connected to extension rod 213. This rotatable connection between driven link 212 and extension rod 213 on rotating link 211 constitutes a key node for motion conversion. The specific position of this connection point on extension rod 213 optimizes the distribution ratio of transmitted torque. The way driven link 212 is connected to extension rod 213 allows it to more effectively convert the oscillation of rotating link 211 into linear displacement of transition plate 320 during motion, while reducing energy loss during motion transmission.

[0097] In the structure without the extension rod 213, the driven link 212 near the middle of the air outlet 110 is directly connected to the rotating link 211 near the end of the air outlet 110. This connection method results in a significant angular deviation between the driven link 212 and the rotating link 211, causing the direction of force transmission to be inconsistent with the ideal direction of motion of the driven link 212. During the movement, the force applied by the rotating link 211 is decomposed into an effective driving force and an ineffective lateral force, with the lateral force component significantly increasing the frictional resistance of the connecting pair.

[0098] In the structure with extension rod 213, the extension rod 213 extends along the length of the air guide plate 200, moving the connection point of the driven link 212 to a position more aligned with the direction of motion. This arrangement improves the force transmission angle, making the direction of the force applied by the rotating link 211 more consistent with the ideal direction of motion of the driven link 212. The lever effect of the extension rod 213 optimizes the force decomposition ratio and reduces ineffective lateral force components.

[0099] In one possible implementation, there may be two connecting components 210, and the two rotating links 211 may be connected to the ends of the air guide plate 200 respectively to form a balanced force transmission system, providing symmetrical driving force to the air guide plate 200.

[0100] The number of adjusting components 300 can be two, and each transition plate 320 is connected to the rotating link 211 through a driven link 212. The two transition plates 320 are respectively arranged on both sides of the air guide plate 200, and each is connected to the corresponding rotating link 211 through an independent driven link 212.

[0101] Therefore, the two adjustment components 300 can be positioned closer to and further away from the air outlet 110, enabling the airflow guidance system to achieve precise zoned control. Each adjustment component 300 corresponds to a different air supply zone; the left adjustment component 300 controls the airflow distribution on the left, while the right adjustment component 300 independently regulates the airflow direction on the right, thus forming two relatively independent yet collaborative air supply zones. This independent drive mode completely decouples the adjustment of the two air supply zones, allowing users to set the optimal air supply parameters for each side according to the actual indoor layout. For example, the adjustment component 300 on the side closer to the activity area can be set to a large-angle air supply, while the other side can use a small-angle diffusion mode to achieve differentiated airflow distribution. This arrangement significantly expands the overall air supply coverage, enabling the indoor unit to adapt to a wider range of spatial layouts.

[0102] The two regulating components 300 can also deliver air to different areas, each with its own air delivery zone, thus expanding the air delivery area. Furthermore, the two regulating components 300 can be independently driven by two separate drive components, allowing for independent adjustment of their air delivery zones without any linkage between them. This makes the indoor unit suitable for different indoor layouts and usage needs, allowing users to flexibly adjust the air delivery zones of the two regulating components 300 according to actual conditions. This meets the needs of different environments for different air delivery zones, ensuring that the airflow blown by the indoor unit is fully and effectively utilized, avoiding waste.
