The air guide plate is rotatably connected to the air outlet, and the airflow direction of the air outlet is changed by changing the angle at which the air guide plate opens relative to the air outlet.

[0003] The air outlet can also be equipped with an air guide structure to further adjust the air supply method and make the airflow more stable and comfortable.

[0004] These types of air guide structures are usually installed using mechanical connections, which can create frictional resistance during operation, affecting the operation of the air guide structure. Utility Model Content

[0010] In the thickness direction of the base plate, at least a portion of the rolling element is located inside the base plate.

[0011] In some possible implementations, the rolling element is configured as a roller, and the rotation axis of the roller is rotatably connected to the side wall of the mounting groove;

[0012] At least a portion of the roller extends out of the base plate, and the portion of the roller extending out of the base plate forms the contact surface and is used for rolling contact with the mounting bracket.

[0013] In some possible implementations, the rotation axis of the roller is arranged perpendicular or approximately perpendicular to the line connecting the first position and the second position.

[0014] In some possible implementations, the rolling element is configured as a ball bearing, which is embedded in the mounting groove.

[0015] In some possible implementations, the diameter of the mounting groove opening is smaller than the diameter of the ball to prevent the ball from disengaging from the mounting groove.

[0016] In some possible implementations, as the base plate moves along a predetermined path between the first position and the second position, the base plate moves toward the front center of the mounting bracket.

[0017] In some possible implementations, as the base plate moves along a predetermined path between the first position and the second position, the rolling element moves toward the front center of the mounting bracket.

[0040] 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

[0041] As mentioned in the background section, air handling equipment, taking air conditioning equipment as an example, typically has an air deflector at the air outlet. The air deflector is connected to the air outlet by rotation, and the airflow direction is adjusted by changing its opening angle relative to the air outlet. The airflow angle adjustment mainly relies on blades, which are generally fixed in a local area of ​​the air outlet and are pulled by a lever to achieve one-dimensional rotation, thereby achieving left-right sweeping or up-down oscillation.

[0042] However, the aforementioned adjustments to the air supply direction and angle have several drawbacks. Firstly, the area of ​​the air supply zone is directly proportional to the area of ​​the air outlet, limiting the adjustable air supply angle and resulting in a smaller air supply coverage area for the air conditioning unit, making it difficult to meet the air supply needs of large areas. Secondly, because the blades are located within the air duct and can only deflect at the same angle, blind spots can easily appear when adjusting the air supply angle, leading to significant indoor temperature differences and greatly affecting comfort.

[0043] To address the aforementioned issues, an air guide structure can be installed at the air outlet to control the air delivery angle, adapting to different room layouts and user needs. This helps reduce blind spots in air delivery and optimize airflow distribution.

[0044] However, traditional air guide structures are usually installed through mechanical connections. This method may generate frictional resistance during adjustment or operation, which may cause the air guide structure to move less smoothly, affecting the accuracy of air delivery angle control and the durability of the equipment.

[0045] In view of this, the embodiments of this application provide an air guiding structure that reduces the friction between the adjusting component and the bracket by using rolling elements, making the operation of the adjusting component on the mounting bracket smoother and thus improving the accuracy of air delivery angle control; the adjusting component moves on the mounting bracket through the rolling elements, avoiding friction and wear between them and improving the durability of the equipment; by adjusting the range of motion of the component, the air guiding structure can cover a larger air delivery angle, reduce air delivery blind spots, and meet the air delivery needs of large areas; more uniform airflow distribution reduces indoor temperature differences and improves the user's comfort experience.

[0046] 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 conditioners, ducted air conditioners, etc., a wall-mounted air conditioner is specifically used as an example for description below.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions 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.

[0048] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. In embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0049] refer to Figures 1-5 This application provides an air guide structure, including a mounting bracket 100 and an adjustment component 200.

[0050] The adjustment component 200 is movably mounted on the mounting bracket 100.

[0051] When the adjustment component 200 is in the first position, the adjustment component 200 is located inside the mounting bracket 100; when the adjustment component 200 is in the second position, at least a portion of the adjustment component 200 extends out of the mounting bracket 100.

[0052] The adjustment assembly 200 is provided with at least one rolling element 300, which is movable relative to the adjustment assembly 200. The rolling element 300 has a contact surface and makes rolling contact with the mounting bracket 100 through the contact surface.

[0053] It is known that the mounting bracket 100 is used to fix and support the entire air guide structure; the adjustment assembly 200 is designed to allow movement between the inside and outside of the mounting bracket 100.

[0054] When the adjustment component is in the first position, it is completely inside the mounting bracket 100, at which point the air guide structure is in the initial or retracted state; when the adjustment component is in the second position, it extends at least partially out of the mounting bracket 100, at which point the air guide structure is deployed to the outside of the air handling unit to adjust the air delivery angle.

[0055] The rolling element 300 makes rolling contact with the mounting bracket 100 through its contact surface, changing the sliding contact between the adjusting component 200 and the mounting bracket 100, reducing frictional resistance, and making the movement of the adjusting component 200 smoother. At the same time, the use of the rolling element 300 can improve the accuracy of adjustment, because rolling friction is usually less than sliding friction, reducing energy loss and structural wear caused by friction.

[0056] Therefore, by using the rolling element 300, the friction between the adjusting component 200 and the bracket 100 is reduced, making the operation of the adjusting component 200 on the mounting bracket 100 smoother, thereby improving the accuracy of the air supply angle control; the adjusting component 200 moves on the mounting bracket 100 through the rolling element 300, avoiding friction and wear between them, and improving the durability of the equipment; by adjusting the range of motion of the adjusting component 200, the air guide structure can cover a larger air supply angle, reduce air supply blind spots, and meet the air supply needs of large areas; a more uniform airflow distribution reduces indoor temperature differences and improves the user's comfort experience.

[0057] In some possible implementations, the adjustment assembly 200 includes a base plate 210 with a mounting groove 211, and the rolling element 300 is disposed in the mounting groove 211.

[0058] In the thickness direction of the base plate 210, at least a portion of the rolling element 300 is located inside the base plate 210.

[0059] It is understandable that the rolling element 300 is located within the mounting groove 211 and can roll within the mounting groove 211, with the portion protruding from the mounting groove 211 making rolling contact with the mounting bracket 100.

[0060] In this way, the design of the mounting groove 211 allows the rolling element 300 to be partially embedded within the base plate 210, thereby reducing external protrusions. This not only reduces the design distance between the base plate 210 and the mounting bracket 100, optimizing structural compactness and saving internal space, allowing for more flexible design and layout, but also prevents excessive distance between the base plate 210 and the mounting bracket 100, which could lead to unstable operation and shaking of the base plate 210. At least a portion of the rolling element 300 is located inside the base plate 210. This ensures that the rolling element 300 has sufficient support and protection within the base plate 210, reducing external interference. The partial embedding of the rolling element 300 inside the base plate 210 provides better support and stability, reducing structural deformation or damage caused by external impacts or vibrations.

[0061] refer to Figures 4-7 In some possible implementations, the rolling element 300 is configured as a roller, and the rotation axis of the roller is rotatably connected to the side wall of the mounting groove 211.

[0062] At least a portion of the roller extends out of the base plate 210, and the portion of the roller extending out of the base plate 210 forms a contact surface and is used for rolling contact with the mounting bracket 100.

[0063] It is known that the rolling element 300 is designed as a roller that can rotate freely on its axis of rotation. This connection method allows the roller to rotate freely in the groove, reducing friction. At least part of the roller extends out of the base plate 210, so that the outer part of the roller can form a contact surface with the mounting bracket 100. This design allows the roller to roll on the mounting bracket instead of sliding, thereby reducing frictional resistance.

[0064] With this design, the movement of the air guide structure changes from sliding friction to rolling friction, significantly reducing frictional resistance. This makes the air supply adjustment process smoother and reduces energy loss. The reduction in rolling friction allows for more precise adjustment of the air supply angle, enabling users to control the air supply direction more flexibly to meet different room layouts and user needs. Due to the reduction in friction, wear on rollers and other structural components is reduced, extending the service life of the equipment.

[0065] In some possible implementations, the rotation axis of the roller is set perpendicular or approximately perpendicular to the line connecting the first position and the second position.

[0066] It is understandable that the rotation axis of the roller is set perpendicular or nearly perpendicular to the line connecting the first position and the second position. This setting ensures that the roller can effectively roll on the mounting bracket 100 instead of sliding when it rotates within the base plate 210, thus ensuring that the relative movement between the base plate 210 and the mounting bracket 100 is always supported by the rolling friction of the roller.

[0067] Because the rotating shaft is perpendicular or nearly perpendicular to the direction of movement, the roller can roll smoothly when the base plate 210 moves, reducing frictional resistance and avoiding contact between the roller's contact surface and the mounting bracket 100. The reduction in rolling friction makes the adjustment of the air guide structure more precise and flexible, allowing for better control of the air delivery direction. Reducing friction not only improves the smoothness of adjustment but also reduces the wear of the roller and related components, extending the service life of the equipment.

[0068] In some possible implementations, the rolling element 300 is configured as a ball bearing, which is embedded in the mounting groove 211.

[0069] It is known that the design of the mounting groove 211 ensures that the ball can be securely embedded in it, while allowing the ball to roll freely in the groove. This design provides support and guidance for the ball.

[0070] The use of ball bearings transforms sliding friction into rolling friction, significantly reducing frictional resistance. This makes the adjustment of the air guide structure smoother and reduces energy loss.

[0071] refer to Figure 8 In some possible implementations, the diameter of the mounting groove 211 is smaller than the diameter of the ball to prevent the ball from disengaging from the mounting groove 211.

[0072] Understandably, because the diameter of the mounting groove 211 is designed to be smaller than the diameter of the ball, it provides a physical constraint, allowing the ball to roll freely within the mounting groove 211 without detaching from it.

[0073] By designing the groove diameter to be smaller than the ball diameter, the ball is effectively confined within the mounting groove, preventing it from falling out during equipment vibration or movement. The ball can roll freely within the groove, reducing resistance from sliding friction and making the adjustment of the air guide structure smoother. Because the ball is confined within the groove, equipment malfunctions caused by ball falling out are reduced, improving the reliability and durability of the equipment.

[0074] In some possible implementations, as the base plate 210 moves along a set path between a first position and a second position, the base plate 210 moves toward the front center of the mounting bracket 100.

[0075] It is known that the base plate 210 moves between the first and second positions along a set path. This path design ensures that the base plate remains stable and controlled during the movement. During the movement, the base plate 210 moves toward the front center of the mounting bracket 100. This direction of movement helps to optimize the contact and support between the base plate 210 and the mounting bracket 100.

[0076] By setting a path, the movement of the base plate 210 is more stable, reducing unnecessary friction and energy loss; the movement of the base plate 210 along the set path ensures the accuracy and consistency of the air supply angle adjustment, meeting the needs of different room layouts and users; the movement of the base plate 210 toward the front center of the mounting bracket 100 provides better support and stability, reducing structural deformation caused by vibration or asymmetrical load.

[0077] For example, there are multiple scroll members 300, including a first scroll member and a second scroll member.

[0078] The first rolling element is located near the edge of the mounting bracket 100, and the second rolling element is located near the middle of the mounting bracket 100.

[0079] It can be understood that there are multiple rolling elements to ensure that the base plate 210 is adequately supported and guided during movement; the first rolling element is close to the edge of the mounting bracket 100 and provides edge support to prevent the base plate 210 from tilting or shifting during movement; the second rolling element is close to the middle of the mounting bracket 100 and provides central support to ensure that the base plate remains stable throughout the entire movement path.

[0080] The configuration of multiple rolling elements 300 provides uniform support, preventing the base plate from tilting or becoming unstable during movement. The reasonable distribution of the rolling elements 300 ensures that the contact surface between the base plate 210 and the mounting bracket 100 remains stable during movement, reducing frictional resistance. Through the combined action of the first rolling element at the edge and the second rolling element in the middle, the movement of the base plate 210 is more precise, and the adjustment of the air delivery angle is more accurate. The arrangement of multiple rolling elements 300 can also evenly support the base plate 210, dispersing the pressure of the base plate 210 on the mounting bracket and preventing equipment deformation.

[0081] In some possible implementations, as the base plate 210 moves along a set path between a first position and a second position, the rolling element 300 moves toward the front center of the mounting bracket 100.

[0082] refer to Figures 1-4 In some possible implementations, the adjustment assembly 200 includes a plurality of air guide vanes 220 disposed on the base plate 210, the air guide vanes 220 being disposed on the front side of the base plate 210.

[0083] It is known that the air guide vane 220 is used to guide and adjust the airflow direction. By changing the angle of the air guide vane 220, precise control of the airflow direction can be achieved.

[0084] The multiple air guide vanes 220 allow for fine-tuning of airflow to adapt to different room layouts and user needs; by precisely controlling the air delivery angle, the air guide vanes 220 can effectively reduce blind spots in air delivery and ensure uniform airflow distribution; a more uniform airflow distribution reduces indoor temperature differences and improves user comfort.

[0085] In some embodiments, the air guide vane 220 is disposed on the front side of the base plate 210.

[0086] By placing the air guide vane 220 on the front side of the base plate 210, closer to the air outlet area, the air guide vane 220 can guide and adjust the airflow just as it leaves the air outlet area, thereby achieving more timely and effective airflow control.

[0087] In addition, the air guide blade 220 is located on the front side of the base plate 210, making it less likely to be blocked by other components. The length of the air guide blade 220 can be set to be longer to improve the air guiding effect.

[0088] refer to Figures 1-2 For example, the adjustment component 200 includes a first adjustment component and a second adjustment component. When the first adjustment component and the second adjustment component are in the first position, the length directions of the first adjustment component and the second adjustment component are on the same straight line. When the first adjustment component and the second adjustment component are in the second position, the ends of the first adjustment component and the second adjustment component that are close to each other extend forward toward the mounting bracket 100.

[0089] In the first position, the first and second adjustment components are aligned along their lengths, forming a straight line. This alignment provides a basic airflow pattern, which can be used for standard or default airflow requirements. By aligning the two components, the airflow can be distributed along a uniform direction, ensuring airflow stability and consistency in the basic configuration.

[0090] In the second position, the adjacent ends of the first and second adjustment components extend forward from the mounting bracket 100. This arrangement allows the adjustment component 200 to change the direction and coverage of the airflow in the second position. By allowing the adjacent ends to extend forward, the airflow guide structure can direct the airflow to a specific area, increasing the flexibility and coverage of the air supply. This configuration helps reduce blind spots in the air supply and provides a more concentrated airflow distribution.

[0091] Specifically, through the coordinated operation of multiple adjustment components 200, the air guide structure can adapt to more complex air supply requirements and provide diverse airflow direction options. The configuration of adjustment components 200 in different positions ensures more precise and controllable adjustment of the airflow direction, allowing for flexible adjustments according to specific needs.

[0092] In this way, the first and second regulating components can supply air to different areas, each with its own air supply zone, thus expanding the air supply area of ​​the air guide structure and the air handling unit's coverage area. Furthermore, the first and second regulating components can be driven independently, and their air supply zones can be adjusted independently without any linkage between them. This allows the air handling unit to be adapted to different indoor layouts and usage needs. Users can flexibly adjust the air supply zones of the first and second regulating components according to actual conditions to meet the needs of different environments for different air supply zones, ensuring that the airflow blown by the air handling unit is fully and effectively utilized and avoiding waste.

[0093] This application provides an indoor unit, including an evaporator, a condenser, and a compressor, as well as the aforementioned air guide structure.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] In some possible implementations, the indoor unit can be a wall-mounted air conditioner.

[0099] It should be noted that the indoor unit can also be a cabinet air conditioner, a portable air conditioner, etc., and this application does not impose any special limitations on the embodiments.
