Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide device, an air supply structure and an air conditioner. Background Art

[0002] With the continuous development of the air conditioning market, consumers' core demands for air conditioning products have shifted from simple cooling and heating performance to a comprehensive consideration of comfort and health. Traditional air conditioning products often achieve rapid cooling or heating effects by increasing air volume, but this approach is often accompanied by a strong sense of airflow impact, which can easily cause human discomfort (such as localized excessive wind and dryness). Against this backdrop, distributed air supply technology has gradually become a direction of innovation in the industry. Its core concept is to achieve a user experience where "the wind does not blow on you" by optimizing the air supply path and air outlet form, thereby significantly improving human comfort.

[0003] However, existing distributed air supply technology still has the following limitations:

[0004] 1. Although distributed air supply technology disperses the airflow by supplying air at multiple points, when the air outlet is open, the airflow may still form local impact due to concentrated injection, making it difficult to completely avoid direct impact on indoor personnel.

[0005] 2. Most distributed air supply products are not equipped with left and right sweeping blades, resulting in a small air outlet area and a highly concentrated air flow. This can easily cause a strong wind sensation in specific areas, affecting overall comfort.

[0006] 3. In the sweeping mode, some distributed air-supply air conditioners equipped with sweeping blades have uneven airflow distribution due to changes in blade angles, which causes periodic fluctuations in the airflow, thereby reducing the air supply stability and comfort. Summary of the Invention

[0007] The purpose of the present invention is to provide an air guide device, an air supply structure and an air conditioner, aiming to solve the problems of the existing air supply technology such as insufficient comfort.

[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0037] See also Figure 1 and Figure 2 The present embodiment provides an air guide device, comprising: an air guide body 1, on which a first arched curve portion 2 and a second arched curve portion 3 are provided, the first arched curve portion 2 and the second arched curve portion 3 are arranged opposite to each other, the first arched curve portion 2 protrudes toward a first direction and forms a tip 4, and the second arched curve portion 3 is recessed toward the first direction and forms an open end 5.

[0038] This embodiment provides a first arcuate curved portion 2 and a second arcuate curved portion 3. The first arcuate curved portion 2 is convex in the first direction to form a tip 4, while the second arcuate curved portion 3 is concave in the first direction to form an open end 5. This allows the airflow to converge or diverge. Its unique curved structure reduces local resistance in the flow field, effectively controlling the direction of the airflow, improving the aerodynamic performance of the flow channel, and guiding the outflow direction of the airflow, thereby reducing aerodynamic noise within the air duct. This also achieves the goal of wide-area air delivery, significantly increasing the airflow coverage area. Its simple structure and low local resistance improve user comfort without sacrificing air volume.

[0039] Specifically, the first arcuate curved portion 2 is convex in a first direction (e.g., the front side) and has a tip 4 formed at its front end to enhance airflow guidance. The second arcuate curved portion 3 is concave in the same first direction (the front side) and has an open end 5 formed at a corresponding position to form an airflow diffusion channel.

[0040] The raised height of the first arched curve portion 2 and the recessed depth of the second arched curve portion 3 are designed according to the size ratio of the air guide body 1. For example, the raised height is 1 / 4 to 1 / 3 of the thickness of the air guide body 1, and the recessed depth is 1 / 5 to 1 / 2 of the thickness of the air guide body 1, to ensure that the spatial coordination between the two can guide the airflow to form a diffusion or gathering effect.

[0041] In this embodiment, the central axes of the first arcuate curve portion 2 and the second arcuate curve portion 3 coincide with each other.

[0042] The central axes of the first arched curve portion 2 and the second arched curve portion 3 coincide. This design allows the entire air guide body 1 to form a symmetrical structure, providing a basis for the stable guidance of the airflow. The two arched curves are distributed around the same central axis. The symmetrical layout ensures that the airflow is more evenly guided in the force and flow direction when flowing through the first arched curve portion 2 and the second arched curve portion 3, avoiding the deviation or turbulence of the airflow caused by the offset of the central axis. This structure with overlapping central axes, combined with their respective specific curve parameters, can accurately control the convergence or divergence of the airflow, while ensuring that the local resistance of the air guide device in the flow field is small, effectively improving the aerodynamic performance of the flow channel, and achieving stable guidance of the outflow direction of the airflow.

[0043] In this embodiment, the opening angles of the first arcuate curve portion 2 and the second arcuate curve portion 3 are different.

[0044] The opening angles of the first arched curve portion 2 and the second arched curve portion 3 are different. This differentiated angle design is the key to achieving precise control of airflow. Specifically, the first curve portion has a relatively large opening angle and a wider outline, which is intended to initially guide and diffuse the main body of the airflow; while the second curve portion adopts a relatively small opening angle to form a more concentrated arc, which is used to perform secondary shaping and acceleration of the airflow on the basis of preliminary guidance. The two curves transition smoothly at the connection point, together forming a continuous profile with excellent aerodynamic performance. By accurately calculating and setting the different opening angles of the two curve portions, the air guide device can effectively change the airflow shape according to the preset purpose regardless of whether the tip 4 or the open end 5 is facing the wind. It can be fully diffused to achieve wide-area soft air supply, or it can be gathered to increase the air supply distance, while maintaining low local resistance and airflow fluctuations throughout the process, ultimately significantly improving the comfort and stability of the air supply.

[0045] Furthermore, the curve equations of the first arcuate curve portion 2 and the second arcuate curve portion 3 are:

[0046]

[0047] Where y represents the vertical coordinate; y0 represents the reference offset; A represents the amplitude; x represents the horizontal coordinate; x crepresents the central abscissa of the curve; w represents the width scaling factor of the curve.

[0048] Specifically, y represents the ordinate of the curve in the rectangular coordinate system, which is used to locate the vertical position of a certain point on the curve; y0 represents the reference offset, which determines the reference position of the entire curve in the vertical direction and provides basic positioning for the curve; A represents the amplitude, which reflects the maximum distance the curve deviates from the reference offset y0 and directly affects the degree of curvature of the curve; x represents the abscissa of the curve in the rectangular coordinate system, which is used to determine the horizontal position of a certain point on the curve; x c It represents the horizontal coordinate of the center of the curve, that is, the center of symmetry of the curve in the horizontal direction, and is the reference point for the horizontal positioning of the curve; w represents the width scaling factor of the curve, which is used to adjust the extension range of the curve in the horizontal direction and affect the overall width of the curve.

[0049] In terms of specific parameters, the equation parameters of the first arcuate curve portion 2 are set as y0=70±10, x c =4±0.4, w=4.6±0.4, A=49±6; the equation parameters of the second arcuate curve portion 3 are y0=152±20, x c =3.6±0.3, w=5.6±0.5, A=24.3±3. Through the combination of these parameters, the two arched curves form different opening angles while coinciding with the central axis, thereby effectively guiding the convergence or divergence of the airflow, while ensuring that the local resistance of the air guide body 1 in the flow field is small, which helps to improve the aerodynamic performance of the flow channel.

[0050] In this embodiment, the air guide body 1 is a plate-like structure, and the first arcuate curve portion 2 and the second arcuate curve portion 3 are disposed at opposite ends of the plate-like structure.

[0051] The air guide body 1 is a plate-like structure, and its overall shape is composed of a first bow-shaped curve portion 2 and a second bow-shaped curve portion 3, wherein the first bow-shaped curve portion 2 and the second bow-shaped curve portion 3 are respectively arranged at opposite ends of the plate-like structure. The design of the plate-like structure makes the air guide body 1 have a certain rigidity, which can be stably fixed inside the air outlet duct 6 of the air-conditioning cabinet, and its flat base provides a basic carrier for the formation of the two bow-shaped curve portions. The first bow-shaped curve portion 2 is located at one end of the plate-like structure, protruding in the first direction to form a tip 4; the second bow-shaped curve portion 3 is located at the other end of the plate-like structure, and is recessed in the first direction to form an open end 5. The two are relatively distributed on the plate-like structure, with the central axes coinciding and the opening angles being different. This layout method on the plate-like structure not only ensures that the two bow-shaped curve portions can each play the role of guiding the airflow, but also makes the structure of the entire air guide body 1 more compact, which is convenient for fitting with the inner wall of the air outlet duct 6. At the same time, it is beneficial to reduce the local resistance in the flow channel and improve the stability of the airflow.

[0052] In this embodiment, the air guide body 1 is made of carbon fiber reinforced polymer composite material.

[0053] The air guide body 1 is made of carbon fiber reinforced polymer composite material, which has the characteristics of high strength and light weight. It can meet the structural stability requirements of the air guide body 1 under long-term impact of airflow, while effectively reducing the overall weight and reducing the load on the air duct structure when installed in the air outlet duct 6.

[0054] Furthermore, the surface of the air guide body 1 is provided with a bionic micro-groove structure for reducing drag.

[0055] The surface of the air guide body 1 features a bionic micro-groove structure for drag reduction. This structure mimics the texture of shark skin. By forming regularly arranged micro-grooves on the first and second arcuate curve sections 2 and 3 of the air guide body 1, it effectively optimizes the contact between the airflow and the wall. As air flows through the air guide body 1, the bionic micro-groove structure reduces the airflow's adhesion area on the wall, lowering frictional resistance between the airflow and the surface while suppressing turbulence, allowing the airflow to flow more smoothly along the arcuate curve.

[0056] Furthermore, the bionic micro-groove structure is a rib-shaped groove extending along the airflow direction.

[0057] A large number of these microgrooves are arranged in a parallel array on the windward surface of the air guide, particularly on the first and second arcuate curved sections 3, forming a continuous, regular microscopic texture. As air flows over this surface, these rib-like grooves, parallel to the flow direction, effectively limit vertical momentum exchange, inhibiting the generation and development of lateral vortices. They also divide and confine airflow close to the wall within its own grooved channels for directional guidance, significantly reducing wall friction resistance. This unique biomimetic rib-like groove structure, combined with the air guide's macroscopic arcuate aerodynamic design, synergistically optimizes the device's fluid dynamics at both micro and macro scales.

[0058] In some embodiments, the bionic micro-groove structure on the surface of the air guide device is processed into a cross-sectional shape with specific geometric characteristics. Specifically, the cross-sectional shape of the groove is one of V-shaped, U-shaped or trapezoidal. These specific cross-sectional shapes are obtained by molding on the base material of the air guide device through processes such as precision etching, micro-injection molding or laser processing. The V-shaped cross-section is conducive to guiding the airflow to converge to the bottom of the groove, the U-shaped cross-section provides a smoother transition to reduce flow separation, and the trapezoidal cross-section provides a good balance between structural stability and flow field control. Furthermore, the bionic micro-groove structure has precise dimensions at the micron level, and the opening width of the groove top is controlled between 10 microns and 500 microns, while the depth of the groove is controlled between 5 microns and 200 microns. This specific width-to-depth ratio range is the result of fluid dynamics optimization calculations, which aims to ensure that it can effectively limit and guide the microscopic airflow near the wall when the air flows through the surface, thereby achieving a drag reduction effect on a macro scale.

[0059] In some embodiments, the first arcuate curve portion 2 and the second arcuate curve portion 3 are made of flexible material or a movable blade group, and the key parameters of the first arcuate curve portion 2 and the second arcuate curve portion 3 can be dynamically adjusted in small amounts and continuously through a motor or a memory alloy.

[0060] This is achieved specifically through two technical approaches: First, the first and second arcuate curved sections 3 are integrally formed from a continuous piece of flexible material (such as high-strength silicone or a flexible composite material) that undergoes elastic deformation when subjected to force. Second, the first and second arcuate curved sections 3 are constructed from a plurality of independent movable blades connected by hinges or slide mechanisms, with each blade representing a microsegment of the curve. To achieve dynamic adjustment, this embodiment incorporates a drive mechanism: When a micromotor is used, its output shaft is connected to a specific anchor point in the flexible material or a movable joint in the blade group via a connecting rod or gear; when a shape memory alloy is used, a spring or wire made of the alloy is preloaded and installed within the flexible material or along the motion path of the blade group. A controller issues commands to the micromotor or applies a control current to the shape memory alloy element to change its temperature. The drive mechanism then applies a force, causing the flexible material to undergo a controlled bending deformation or causing the blade group to produce relative displacement. This physical change directly leads to small, continuous dynamic changes in the actual physical dimensions corresponding to the key parameters in the curve equation describing its profile, thereby allowing real-time adjustment of the airflow guidance effect without replacing the device.

[0061] See also Figure 3 and Figure 4 This embodiment further provides an air supply structure, including: an air outlet duct 6 and the air guide device of the above embodiment, and the air guide device is installed on the air outlet 7 of the air outlet duct 6.

[0062] The air guide is fixedly mounted within or at the end of the outlet 7 of the air duct 6. Its physical mounting position is closely aligned with the cross-section of the outlet 7. In practice, the plate-like air guide body 1 is mechanically connected or secured to the inner wall of the air duct 6 via its outer edge, ensuring the device remains stable under the influence of airflow. With this mounting configuration, as air flows from the air duct 6 through the fixed air guide, its unique composite arched curve redistributes and directs the airflow, ultimately achieving a wide-area, uniform, and comfortable air delivery pattern.

[0063] See also Figure 5 The area of ​​the high-speed air flow zone inside the flow channel equipped with the air guide device is significantly reduced, the air flow distribution is more uniform, and the vortex area at the outlet section and the corner of the air duct is reduced.

[0064] In this embodiment, a plurality of air guide devices are provided, and the plurality of air guide devices are installed on the air outlet 7 .

[0065] There are multiple bow-shaped air-guiding devices. These devices are installed together in a specific array on the same air outlet 7 cross section of the air-conditioning outlet duct 6. In specific implementation, multiple air-guiding devices are arranged in a parallel manner, and the planes of their plate-like structures remain parallel to each other and are perpendicular to the cross section of the air outlet 7. The installation direction of each air-guiding device remains consistent. Multiple devices are distributed at basically uniform intervals in the width direction of the air outlet 7, and the shapes of their outer edges are all adapted to the inner wall contour of the flow channel, and are firmly installed through mechanical methods such as slot embedding, screw locking or integration with the internal support frame, together forming a complete air supply unit. Through this layout of multiple devices arranged in parallel, the air flow sent out from the air duct is effectively divided into multiple streams, and is guided and redistributed through the unique bow-shaped surface of each air-guiding device, thereby collaboratively achieving coverage of the entire air outlet 7 area without the need for any moving parts, ultimately forming a wide, uniform and well-mixed air supply flow.

[0066] In this embodiment, please refer to Figure 6 The air guide device and the outflow section of the air outlet channel 6 are arranged in parallel.

[0067] Specifically, the overall extension direction of each air-guiding device, that is, the plane formed by its plate-like structure, is set to maintain a strict parallel relationship with the center line or inner wall guide of the outflow section. This parallel layout is achieved by fixing the air-guiding device on a special mounting seat or support frame inside the air duct, ensuring that the long axis direction of the device is completely consistent with the final outflow direction of the airflow. After the airflow enters the final outflow section from the air duct main body, its flow direction has basically stabilized; at this time, the parallel air-guiding devices will not exert additional lateral bending force on the main airflow, but will divide and fine-tune it accordingly. The airflow flows in parallel through the specific surface of each air-guiding device, and its flow path is coordinated with the wall guide of the outflow section, making the device's shaping effect on the airflow smoother and more efficient, minimizing the vortex and energy loss that may be generated by sudden changes in flow direction, and ensuring that the airflow has good directional consistency when flowing out of the air outlet 7.

[0068] In this embodiment, the tip 4 is arranged toward the air outlet 7, and the open end 5 is arranged away from the air outlet 7 (eg Figure 7 shown);

[0069] Alternatively, the opening end 5 is disposed toward the air outlet 7, and the tip 4 is disposed away from the air outlet 7 (e.g. Figure 8 shown).

[0070] In the first configuration mode, the tip 4 of the air guide device is set toward the air outlet 7, while its open end 5 is set away from the air outlet 7. When installed in this direction, the airflow from the flow channel first hits the tip 4 of the air guide device. Under the action of viscous force, the airflow will tend to adhere to and flow outward along the arched curved wall surfaces on both sides, and finally be sent to the wide area on both sides through the open end 5, thereby achieving the effect of airflow diffusion and wide-area air supply, effectively increasing the air supply coverage area. In the second configuration mode, the installation direction of the air guide device is opposite to the first one, that is, the open end 5 is set toward the air outlet 7, and its tip 4 is set away from the air outlet 7. In this mode, the airflow will flow in from the open end 5, and in the process of flowing through the air guide device, it will be constrained and guided by its tapered profile, and finally gathered and sent out from the tip 4, thereby obtaining a concentrated airflow with a longer air supply distance. These two installation directions provide flexible and effective technical means to achieve different air supply requirements (rapid cooling and heating or wide-area windless feeling).

[0071] This embodiment combines the shape of the flow channel itself with the bow-shaped air guide to form a wide-area air supply form. It does not involve a motion mechanism and can reduce the cost of the entire machine. In addition, the air guide itself is a fixed structure, and will not increase the local resistance of the air outlet due to angle changes, which will have a negative impact on the flow field inside the air duct. In this air supply form, the outer edge of the guide device fits the flow channel design. Under the premise of ensuring the two main curve design parameters, the shape of the opening end 5 is adjusted to better fit the air supply flow channel. The outflow section is parallel to the bow-shaped air guide and fixed inside the air duct. The specific structure is shown in Figure 3 and Figure 4 This layout can achieve the goal of wide-area air supply, and the airflow coverage area is significantly improved. Figure 9 As shown, it can be seen that this type of air supply has a significantly improved air flow coverage area compared to the traditional air supply form, and its structure is simple and the local resistance is low, which can improve user comfort without losing air volume.

[0072] This embodiment also provides an air conditioner, including: the air supply structure of the above embodiment.

[0073] Through this air supply structure, the air conditioner uses the bow-shaped air guide device to guide the airflow, achieving wide-area comfortable air supply without affecting the air volume and noise. It effectively solves the problems of traditional distributed air supply air conditioners such as air gathering, easy blowing on people or air flow fluctuations, improves the comfort of indoor people, and meets users' needs for healthy and comfortable air supply.
