Description

Technical Field

[0001] This application relates to the field of air handling equipment technology, and more particularly to an air guide assembly, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] Air handling equipment, taking air conditioning units as an example, typically features guide vanes at the air outlet. These guide vanes are rotatably connected to the outlet, and the airflow direction is adjusted by changing their opening angle relative to the outlet. These guide vanes are generally fixed to a localized area of ​​the outlet and rotated using a lever, thus achieving left-right or up-down airflow.

[0003] Related technologies also include installing a rotatable support structure at the air outlet, with the air guide vanes mounted on it. By controlling the angle of the support structure relative to the air outlet, the air delivery angle can be further controlled, adapting to different room layouts and user needs. This helps reduce blind spots in air delivery and optimize airflow distribution. In traditional installations, the support structure has a mounting slot, and the rotation shaft of the air guide vanes is inserted into the mounting slot.

[0004] However, when the air handling unit needs to adjust the air supply angle during air supply, the air guide vanes will be subjected to the impact force from the airflow. This will increase the friction between the rotation axis of the air guide vanes and the inner wall of the mounting groove, reduce the smoothness of the air guide vane rotation, and even generate greater rotation noise, affecting the user experience. Utility Model Content

[0005] In view of this, this application provides an air guide assembly, an indoor air conditioning unit, and an air conditioner, which can improve the smoothness of the rotation of the air guide blades, avoid generating large rotation noise, and improve the user experience.

[0006] To achieve the above objectives, this application provides an air guide assembly, an indoor air conditioning unit, and an air conditioner, employing the following technical solution:

[0007] In a first aspect, this application provides an air guiding assembly, including a load-bearing structure and air guiding blades;

[0008] The load-bearing structure is provided with a mounting groove, and a first rotating component is provided in the mounting groove;

[0009] The air guide blade has a connecting part, and a second rotating member is sleeved on the outside of the connecting part. The second rotating member is rotatably disposed inside the first rotating member.

[0010] The first rotating member and the second rotating member are spaced apart, and a plurality of rolling members are provided between the first rotating member and the second rotating member. The plurality of rolling members are arranged around the outside of the second rotating member, and the second rotating member makes rolling contact with the first rotating member through the rolling members.

[0011] The above technical solution transforms the sliding friction between the rotating shaft of the traditional guide vane and the inner wall of the mounting groove into rolling friction, significantly reducing rotational resistance. Multiple rolling elements are arranged around the outside of the second rotating element, allowing for even load distribution and preventing localized stress concentration, further reducing frictional losses. The first and second rotating elements are spaced apart, with indirect contact through the rolling elements, avoiding the direct rigid friction between the rotating shaft and the mounting groove found in traditional structures. Even if the guide vane deviates due to airflow impact, the rolling elements maintain smooth rolling, ensuring rotational continuity and reducing jamming or shaking caused by external forces. This reduces the contact area between the guide vane and the inner wall of the mounting groove, and the noise generated by rolling friction is far lower than that of sliding friction, effectively avoiding abnormal noises caused by increased friction in traditional structures.

[0012] In one possible implementation, the air guide assembly provided in this application includes a first rotating member comprising an annular body and an overlapping portion;

[0013] The annular body is located within the mounting groove;

[0014] The overlapping portion is connected to one end of the annular body away from the bottom wall of the mounting groove. The overlapping portion is located outside the mounting groove and can abut against the load-bearing structure.

[0015] The above technical solution forms a double support, limiting the axial displacement of the first rotating component within the mounting groove and preventing positional shifts caused by airflow impact or vibration. It also disperses the torque load during the rotation of the guide vanes, avoiding localized stress concentration and reducing the risk of groove deformation.

[0016] In one possible implementation, the air guide assembly provided in this application has an extension portion provided at the overlapping portion, the extension portion extending toward the second rotating member, and the extension portion abutting against the second rotating member.

[0017] The above technical solution provides auxiliary support for the second rotating component and prevents a large amount of dust or impurities from entering the structure through the gap between the first and second rotating components, thus avoiding the impact of impurities or dust on the rolling of the rolling component and improving the stability of the rolling component.

[0018] In one possible implementation, the air guide assembly provided in this application has an annular body that is interference-fitted with the mounting groove.

[0019] The above technical solution can improve the stability of the annular body installed in the mounting groove.

[0020] In one possible implementation, the air guide assembly provided in this application has a plug-in groove on the supporting structure, and the plug-in groove is spaced around the outside of the mounting groove.

[0021] The overlapping portion is provided with a plug portion, which is spaced apart from the annular body and is inserted into the plug groove.

[0022] Through the above technical solution, the plug-in part acts as an additional fulcrum, dispersing and transferring the torque borne by the wind guide blade to the load-bearing structure, avoiding stress concentration in the annular body or the overlapping part, and reducing the risk of local deformation.

[0023] In one possible implementation, the air guide assembly provided in this application has a first rolling groove on the side wall of the first rotating member facing the second rotating member, and a second rolling groove on the side wall of the second rotating member facing the second rotating member. The openings of the first rolling groove and the second rolling groove are arranged opposite to each other, and the first rolling groove and the second rolling groove together accommodate the rolling member.

[0024] Through the above technical solution, the openings of the first and second rolling grooves are arranged opposite each other to form a closed annular track, which strictly restricts the movement path of the rolling element. This avoids the off-center friction caused by gaps or misalignments in the rolling element in traditional structures, ensuring that the second rotating element always rolls smoothly along the preset trajectory during rotation, and significantly reducing frictional resistance.

[0025] In one possible implementation, the air guide assembly provided in this application has a mounting boss on the bottom surface of the mounting groove, the mounting boss being connected to the side wall of the mounting groove, and the mounting boss being able to support the first rotating member and the second rotating member.

[0026] Through the above technical solution, the mounting boss provides additional support points for the first rotating component and the second rotating component; and by raising the first rotating component, the mounting boss can improve the ease of installation of the first rotating component.

[0027] In one possible implementation, the thickness of the connecting portion of the air guide assembly provided in this application is less than or equal to the thickness of the second rotating member.

[0028] The above technical solution ensures that the sidewalls of the connecting part can be subjected to uniform force, thereby improving the stability of the connecting part and the second rotating component.

[0029] Secondly, this application provides an indoor air conditioning unit, which includes a main body and the aforementioned air guiding assembly;

[0030] The air guide assembly is movably mounted on the main body.

[0031] Thirdly, this application provides an air conditioner, which includes an outdoor unit and the aforementioned indoor unit.

[0032] The air guide assembly, indoor air conditioning unit, and air conditioner provided in this application include an air guide assembly comprising a load-bearing structure and air guide blades. The load-bearing structure has a mounting groove, within which a first rotating component is disposed. The air guide blades have a connecting portion, and a second rotating component is sleeved on the outer side of the connecting portion, rotatably positioned inside the first rotating component. The first and second rotating components are spaced apart, and multiple rolling elements are disposed between them, circumferentially surrounding the outer side of the second rotating component. The second rotating component makes rolling contact with the first rotating component through these rolling elements. By providing multiple rolling elements between the first and second rotating components, the sliding friction between the rotating shaft of the traditional air guide blade and the inner wall of the mounting groove is transformed into rolling friction. The coefficient of rolling friction is much lower than that of sliding friction, significantly reducing rotational resistance. Furthermore, the multiple rolling elements circumferentially surrounding the outer side of the second rotating component evenly bear the load, avoiding localized stress concentration and further reducing friction loss. The spaced-apart arrangement of the first and second rotating components, through indirect contact via the rolling elements, avoids the direct rigid friction between the rotating shaft and the mounting groove in traditional structures. Even if the air guide vanes are deflected by the airflow, the rolling elements can still maintain smooth rolling, ensuring continuous rotation, avoiding excessive rotational noise, and improving the user experience.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0045] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0048] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0050] As mentioned in the background section, air handling equipment, taking air conditioning equipment as an example, typically has air outlets to facilitate air exchange. A guide vane is usually installed at the air outlet. The guide vane is rotatably connected to the air outlet, and the airflow direction is adjusted by changing its opening angle relative to the air outlet. The adjustment of the airflow angle mainly relies on the guide vanes, which are generally fixed in a localized area of ​​the air outlet and rotated one-dimensionally by a lever, thus achieving left-right sweeping or up-down oscillation.

[0051] However, the above-mentioned adjustment of air supply direction and angle has many drawbacks. On the one hand, the area of ​​the air supply area is positively correlated with the area of ​​the air outlet, which limits the adjustable air supply angle and makes the air supply coverage area of ​​the air conditioning equipment smaller. When the area of ​​the air outlet is small, the area of ​​the air supply area that the guide vanes can rotate to deliver air is also small, making it difficult to meet the air supply needs of large areas.

[0052] On the other hand, since the air guide vanes are located inside the air duct and can only deflect at the same rotation angle, blind spots in air supply are easily created when adjusting the air supply angle, resulting in significant indoor temperature differences and greatly affecting the user experience and comfort.

[0053] To address the aforementioned issues, related technologies can also incorporate a rotatable support structure at the air outlet, with guide vanes mounted on it. By controlling the angle of the support structure relative to the air outlet, the air delivery angle can be further controlled, adapting to different room layouts and user needs. This helps reduce blind spots in air delivery and optimizes airflow distribution. For example, the support structure can rotate outwards from the air handling unit, away from the air outlet, carrying the guide vanes away from the fixed air duct. This effectively increases the initial area for airflow diffusion from the air outlet into the environment, thereby increasing the air delivery area. This allows for control of the air delivery angle, adapting to different room layouts and user needs, reducing blind spots in air delivery, and optimizing airflow distribution.

[0054] However, in conventional setups, the supporting structure has a mounting groove, and the rotating shaft of the air guide vane is inserted into the mounting groove. When the air handling equipment needs to adjust the air supply angle during air supply, the air guide vane will be subjected to the impact force from the airflow, which will increase the friction between the rotating shaft of the air guide vane and the inner wall of the mounting groove, reduce the smoothness of the air guide vane rotation, and even generate greater rotation noise, affecting the user experience.

[0055] Based on the aforementioned technical problems, this application provides an air guide assembly, an indoor air conditioning unit, and an air conditioner. In this technical solution, the air guide assembly includes a load-bearing structure and air guide blades. The load-bearing structure has a mounting groove, within which a first rotating member is disposed. The air guide blades have a connecting portion, and a second rotating member is sleeved on the outer side of the connecting portion, rotatably disposed inside the first rotating member. The first and second rotating members are spaced apart, and multiple rolling elements are disposed between them, circumferentially surrounding the outer side of the second rotating member. The second rotating member makes rolling contact with the first rotating member through these rolling elements. By providing multiple rolling elements between the first and second rotating members, the sliding friction between the rotating shaft of the traditional air guide blade and the inner wall of the mounting groove is transformed into rolling friction. The coefficient of rolling friction is much lower than that of sliding friction, significantly reducing rotational resistance. Furthermore, the multiple rolling elements circumferentially surrounding the second rotating member evenly bear the load, avoiding localized stress concentration and further reducing friction loss. The spaced-apart arrangement of the first and second rotating members, through indirect contact via rolling elements, avoids the direct rigid friction between the rotating shaft and the mounting groove in traditional structures. Even if the air guide vanes are deflected by the airflow, the rolling elements can still maintain smooth rolling, ensuring continuous rotation, avoiding excessive rotational noise, and improving the user experience.

[0056] This application provides an air handling device, which includes, but is not limited to, air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air systems. In this application embodiment, an air conditioning unit is used as an example for description. Since air conditioning equipment can include wall-mounted air conditioners, floor-standing air conditioners, central air conditioning systems, ducted air conditioners, etc., the following specifically uses a wall-mounted air conditioner as an example of an air handling device. Figure 1 The following explanation is provided.

[0057] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0058] Reference Figures 1 to 5 As shown in the figure, an air guiding assembly is provided in this application embodiment. The air guiding assembly includes a supporting structure 100 and air guiding blades 200. The supporting structure 100 is rotatably configured relative to the air outlet of the indoor unit of the air conditioner. Figure 1 and Figure 2 As shown, one end of the supporting structure 100 can be located outside the air outlet of the indoor unit of the air conditioner. The supporting structure 100 is equipped with guide vanes 200, which can guide the airflow away from the fixed air duct, effectively increasing the initial area for airflow diffusion from the air outlet into the environment, thereby increasing the air supply area. This allows for control of the air supply angle, adapting to different room layouts and user needs, helping to reduce blind spots in air supply and optimize airflow distribution.

[0059] The load-bearing structure 100 is provided with a mounting groove 101, and a first rotating member 300 is provided in the mounting groove 101; the air guide blade 200 has a connecting part 210, and a second rotating member 400 is sleeved on the outside of the connecting part 210, and the connecting part 210 and the second rotating member 400 can be fixedly connected.

[0060] The second rotating member 400 is rotatably disposed inside the first rotating member 300; the first rotating member 300 and the second rotating member 400 are spaced apart, and a plurality of rolling elements (not shown in the figure) are disposed between the first rotating member 300 and the second rotating member 400. It can be understood that the rolling elements can be balls or rollers, and in this embodiment, the rolling elements are preferably balls.

[0061] Multiple rolling elements are arranged around the outside of the second rotating element 400, and the second rotating element 400 makes rolling contact with the first rotating element 300 through the rolling elements.

[0062] By setting multiple rolling elements between the first rotating member 300 and the second rotating member 400, the sliding friction between the rotating shaft of the traditional guide vane 200 and the inner wall of the mounting groove 101 is converted into rolling friction. The coefficient of rolling friction is much lower than that of sliding friction, significantly reducing rotational resistance. The multiple rolling elements are arranged around the outside of the second rotating member 400, and the multiple rolling elements can evenly bear the load, avoiding local stress concentration and further reducing friction loss.

[0063] The first rotating component 300 and the second rotating component 400 are spaced apart and indirectly contact each other through rolling elements, avoiding the direct rigid friction between the rotating shaft and the mounting groove 101 in the traditional structure. Even if the guide vane 200 is deflected by the airflow impact, the rolling elements can still maintain smooth rolling, ensuring rotational continuity and reducing jamming or shaking caused by external forces.

[0064] In addition, by setting rolling elements, the contact area between the air guide vane 200 and the inner wall of the mounting groove 101 is reduced, and the noise generated by rolling friction is much lower than that of sliding friction, which can effectively avoid the abnormal noise caused by increased friction in traditional structures.

[0065] In one possible implementation, the first rotating member 300 includes an annular body 310 and an overlapping portion 320; the annular body 310 is located inside the mounting groove 101; the overlapping portion 320 is connected to one end of the annular body 310 away from the bottom wall of the mounting groove 101, the overlapping portion 320 is located outside the mounting groove 101, and the overlapping portion 320 can abut against the supporting structure 100.

[0066] Thus, the overlapping portion 320 extends to the outside of the mounting groove 101 and directly abuts against the supporting structure 100, forming a double support. The overlapping portion 320 can limit the axial displacement of the first rotating member 300 within the mounting groove 101, preventing positional displacement caused by airflow impact or vibration. External forces are transmitted through the contact surface between the overlapping portion 320 and the supporting structure 100, dispersing the torque load when the guide vane 200 rotates, avoiding local stress concentration, and reducing the risk of deformation of the mounting groove 101.

[0067] In practice, the overlapping part 320 is also a ring structure. The overlapping part 320 is integrally formed with the ring body 310, which can further improve the structural strength of the first rotating part 300.

[0068] In one possible implementation, the overlapping portion 320 is provided with an extension portion 330, which extends toward the second rotating member 400 and abuts against the second rotating member 400.

[0069] In a specific implementation, the extension 330 is configured as a ring structure, with its top surface coplanar with the top surface of the overlapping portion 320. The extension 330 can be made of a flexible material, extending towards and abutting against the second rotating member 400 to form auxiliary support for it, effectively suppressing radial displacement or tilting of the second rotating member 400 when impacted by airflow. Through physical limiting, the rolling contact between the second rotating member 400 and the first rotating member 300 is always kept aligned, avoiding increased frictional resistance or jamming due to misalignment. Furthermore, the extension 330, extending towards the second rotating member 400, covers at least part of the gap between the first and second rotating members 300, preventing a large amount of dust or impurities from entering the structure through this gap, thus avoiding any impact on the rolling motion of the rolling member and improving its stability.

[0070] In one possible implementation, the annular body 310 is interference-fitted with the mounting groove 101. This interference fit ensures the annular body 310 is tightly embedded within the mounting groove 101, forming a rigid connection. This effectively prevents the first rotating component 300 from shifting or loosening under airflow impact or frequent rotation, ensuring the relative positional accuracy of the first rotating component 300 and the second rotating component 400. This provides a stable reference for the smooth rolling of the rolling elements, thereby guaranteeing the accuracy of the rotation of the guide vane 200. In conventional structures, the rotating shaft directly slides and rubs against the inner wall of the mounting groove 101. The interference fit, however, press-fits the annular body 310, preventing relative movement between it and the mounting groove 101, relying solely on the rolling elements for rotation. This design avoids direct friction between the rotating shaft and the groove wall, significantly reducing frictional resistance and wear rate.

[0071] In one possible implementation, the supporting structure 100 is provided with a insertion groove 102, which is spaced around the outside of the mounting groove 101. An insertion part 340 is provided on the overlapping part 320, spaced apart from the annular body 310, and inserted into the insertion groove 102. After the insertion part 340 is inserted into the insertion groove 102 of the supporting structure 100, the rigidity of the groove body limits the first rotating member 300, preventing it from loosening due to airflow impact or frequent rotation. The insertion part 340 acts as an additional fulcrum, distributing the torque borne by the guide vane 200 to the supporting structure 100, avoiding stress concentration in the annular body 310 or the overlapping part 320, and reducing the risk of local deformation. The engagement between the insertion slot 102 and the insertion part 340 provides a clear assembly guide for the first rotating component 300, ensuring its coaxiality with the second rotating component 400 and reducing issues such as uneven loading or jamming of the rolling elements due to installation deviations. This enhances the first rotating component 300's resistance to loosening, especially in scenarios involving long-term vibration or high-frequency air conditioning, preventing structural failure caused by fatigue loosening of the interference fit.

[0072] In one possible implementation, a first rolling groove 301 is provided on the side wall of the first rotating member 300 facing the second rotating member 400, and a second rolling groove 401 is provided on the side wall of the second rotating member 400 facing the second rotating member 400. The openings of the first rolling groove 301 and the second rolling groove 401 are arranged opposite to each other, and the first rolling groove 301 and the second rolling groove 401 together accommodate the rolling member.

[0073] With the above arrangement, the openings of the first rolling groove 301 and the second rolling groove 401 are positioned opposite each other, forming a closed annular track, which strictly restricts the movement path of the rolling element. This avoids the off-center friction caused by gaps or misalignments in the rolling element in traditional structures, ensuring that the second rotating element 400 always rolls smoothly along the preset trajectory during rotation, significantly reducing frictional resistance. In addition, the cooperation of the two rolling grooves can automatically correct the axial deviation of the second rotating element 400, dynamically adjusting its position when the guide vane 200 is impacted by airflow, reducing jamming or shaking caused by external force interference, thereby improving rotational smoothness.

[0074] In practice, the cross-sections of the first rolling groove 301 and the second rolling groove 401 are both arc-shaped. The rolling element can be a ball. When the ball rolls in the first rolling groove 301 and the second rolling groove 401, its contact point changes with the rotation position, which realizes the uniform distribution of wear and avoids the problem of local rapid wear in traditional sliding friction, thereby extending the service life of the rolling element.

[0075] In one possible implementation, the bottom surface of the mounting groove 101 is provided with a mounting boss 500, which is connected to the side wall of the mounting groove 101. The mounting boss 500 can support the first rotating member 300 and the second rotating member 400.

[0076] The mounting boss 500 provides additional support points for the first rotating component 300 and the second rotating component 400, dispersing the airflow impact force borne by the guide vane 200 to the side wall of the mounting groove 101, thus avoiding deformation or fatigue damage caused by local stress concentration. The mounting boss 500 elevates the first rotating component 300, improving the ease of installation of the first rotating component 300.

[0077] To further improve the connection stability between the connecting portion 210 and the second rotating member 400, the thickness of the connecting portion 210 is less than or equal to the thickness of the second rotating member 400. Specifically, the projection of the connecting portion 210 toward the second rotating member 400 is located inside the second rotating member 400 to ensure that the sidewall of the connecting portion 210 can be evenly stressed, thereby improving the stability of the connecting portion 210 and the second rotating member 400.

[0078] In one possible implementation, this application provides an indoor air conditioning unit, including a body, an evaporator, a condenser, a compressor, and the aforementioned drive mechanism.

[0079] The indoor unit of the air conditioner has an air outlet, and a supporting structure 100 is provided at the air outlet. The supporting structure 100 can be movably mounted on the unit.

[0080] It is important to know that the evaporator, condenser, and compressor are the core components of refrigeration equipment, and they work together to achieve the refrigeration cycle.

[0081] The evaporator is the component in a refrigeration system responsible for absorbing heat. In the evaporator, liquid refrigerant absorbs heat from the surrounding air and evaporates into a gas. This process lowers the temperature of the surrounding air, thus achieving a cooling effect.

[0082] The condenser is the component in a refrigeration system responsible for releasing heat. In the condenser, the gaseous refrigerant releases heat and condenses into a liquid, a process that releases heat into the external environment.

[0083] The compressor is responsible for compressing the refrigerant and driving its circulation in the system. It compresses the low-pressure gaseous refrigerant into a high-pressure gaseous state, thereby increasing its temperature and pressure.

[0084] Air conditioner indoor units equipped with the aforementioned air guide components can avoid generating significant rotational noise, thus improving the user experience.

[0085] In one possible implementation, refer to Figure 6 As shown, the supporting structure 100 is provided with multiple air guide blades 200. In order to drive multiple air guide blades 200 to rotate simultaneously and ensure the consistency of wind direction, a synchronous gear 10 is sleeved on the rotating shaft of each air guide blade 200. A rack 20 is slidably connected inside the supporting structure 100. Each synchronous gear 10 meshes with the rack 20. When one of the air guide blades 200 rotates, the synchronous gear 10 on its rotating shaft drives the rack 20 to move, thereby driving multiple air guide blades 200 to rotate simultaneously.

[0086] This application also provides an air conditioner, which includes an outdoor unit and the above-mentioned indoor unit. For those skilled in the art, the structure of the outdoor unit is easy to understand, and this application does not limit the specific structure of the outdoor unit.

[0087] By incorporating the aforementioned indoor air conditioning unit, the air conditioner can reduce the rotational resistance of the air guide vanes 200, improve rotational smoothness, avoid generating significant rotational noise, and enhance the user experience.

[0088] The implementation principle of an air guide assembly, an indoor air conditioning unit, and an air conditioner according to an embodiment of this application is as follows: The air guide assembly includes a supporting structure 100 and air guide blades 200; the supporting structure 100 is provided with a mounting groove 101, and a first rotating member 300 is disposed within the mounting groove 101; the air guide blades 200 have a connecting portion 210, and a second rotating member 400 is sleeved on the outside of the connecting portion 210, the second rotating member 400 being rotatably disposed inside the first rotating member 300; the first rotating member 300 and the second rotating member 400 are spaced apart, and a plurality of rolling elements are disposed between the first rotating member 300 and the second rotating member 400, the plurality of rolling elements being arranged around the outside of the second rotating member 400, and the second rotating member 400 making rolling contact with the first rotating member 300 through the rolling elements. By providing a plurality of rolling elements between the first rotating member 300 and the second rotating member 400, the sliding friction between the rotating shaft of the traditional air guide blade 200 and the inner wall of the mounting groove 101 is converted into rolling friction. The coefficient of rolling friction is much lower than that of sliding friction, significantly reducing rotational resistance. Furthermore, multiple rolling elements are arranged around the outside of the second rotating element 400, and the load is evenly distributed among the rolling elements, avoiding localized stress concentration and further reducing friction loss. The first rotating element 300 and the second rotating element 400 are spaced apart and indirectly contact each other through the rolling elements, avoiding the direct rigid friction between the rotating shaft and the mounting groove 101 in the traditional structure. Even if the guide vane 200 is deflected by the airflow impact, the rolling elements can still maintain smooth rolling, ensuring rotational continuity, avoiding large rotational noise, and improving the user experience.
