[0037] In related technologies, a multi-split air conditioning system is a type of split-type air conditioning system consisting of one outdoor unit and multiple indoor units. The air outlet grille of a multi-split system is equipped with guide vanes. In some existing technologies, the structural design of the guide vanes in the air outlet grille is unreasonable, which can lead to increased resistance to airflow and resulting in air volume loss.

[0038] The following is for reference. Figures 1-8 Description of an air guide plate assembly 1 for an air conditioning device according to an embodiment of the present invention.

[0039] like Figures 1-6 As shown, the air guide plate assembly 1 for an air conditioning device according to the present invention includes: a frame 10 and a first air guide blade 20. The first air guide blade 20 has a first end 21 and a second end 22 in the extending direction. The first end 21 is disposed on the frame 10. The first air guide blade 20 is constructed to be at least two spaced apart along a first direction. The minimum distance between two adjacent first air guide blades 20 in the first direction is G. The thickness of the first air guide blade 20 is D, and satisfies 1 / 5≤D / G≤1 / 4. The two side surfaces of the first air guide blade 20 in the thickness direction are a pressure surface 23 and a suction surface 24, respectively. The second end 22 also forms a connecting surface 25, which is adapted to be connected to the pressure surface 23 and the suction surface 24, respectively. The distance between the edge of the pressure surface 23 connecting to the connecting surface 25 and the first end 21 is L. The distance between the edge of the suction surface 24 connecting to the connecting surface 25 and the first end 21 is S, and satisfies 0.7≤S / L≤0.9.

[0040] Specifically, the air guide plate assembly 1 can be used as the return air inlet or air outlet of an air conditioning device, and the first air guide blade 20 is used to guide the airflow. When the air guide plate assembly 1 is used as the return air inlet of the air conditioning device, the second end 22 of the first air guide blade 20 can be located upstream of the airflow direction, while the first end 21 is located downstream of the airflow direction. Alternatively, the second end 22 of the first air guide blade 20 can also be located downstream of the airflow direction, while the first end 21 is located upstream of the airflow direction. When the air guide plate assembly 1 is used as the air outlet of the air conditioning device, the second end 22 of the first air guide blade 20 can be located upstream of the airflow direction, while the first end 21 is located downstream of the airflow direction. Alternatively, the air guide plate assembly 1 can also serve as both the return air and air outlet of the air conditioning device. The first air guide blade 20 of the air guide plate assembly 1 can be designed according to actual conditions, and is not limited here. Figure 6 In the specific embodiment shown, the first end 21 is located upstream of the airflow direction, and the second end 22 is located downstream of the airflow direction.

[0041] Here, the first guide vanes 20 are constructed in a configuration of at least two spaced apart along a first direction. An airflow channel suitable for airflow is defined between two adjacent first guide vanes 20. It is understood that the minimum spacing between two adjacent first guide vanes 20 in the first direction should not be too small, and the thickness of the first guide vanes 20 should not be too large, to avoid the first guide vanes 20 affecting the airflow through the airflow channel and thus avoiding impacting the airflow rate. Similarly, the minimum spacing G between two adjacent first guide vanes 20 in the first direction should not be too large, and the thickness of the first guide vanes 20 should not be too small, to ensure that the first guide vanes 20 have a guiding effect on the airflow. Therefore, the minimum spacing G between two adjacent first guide vanes 20 in the first direction and the thickness D of the first guide vanes 20 must satisfy: 1 / 5 ≤ D / G ≤ 1 / 4, to ensure that the first guide vanes 20 have a guiding effect on the airflow while avoiding impacting the airflow rate.

[0042] More specifically, you can refer to Figure 6 The first guide vane 20 has a pressure surface 23 and a suction surface 24 on its two sides in the thickness direction, respectively. The second end 22 also has a connecting surface 25, which is adapted to connect with the pressure surface 23 and the suction surface 24 respectively. The thickness direction of the first guide vane 20 is consistent with the first direction. The first guide vane 20 adopts a streamlined structure of a biomimetic airfoil to guide airflow to form a wall-attaching effect, extending the air delivery distance and allowing the airflow to fully diffuse when passing through the guide vane assembly 1, effectively attenuating the negative pressure effect. (See [reference]). Figure 7 Due to the wall effect, the airflow moves along the edge of the first guide vane 20 and continues to flow in the same direction.

[0043] You can refer to this. Figure 6 To ensure that the first guide vane 20 has a guiding effect on the airflow and to reduce the resistance of the first guide vane 20 to the airflow and the impact on the airflow flow rate, the distance L between the edge connecting the pressure surface 23 and the connecting surface 25 and the first end 21 and the distance S between the edge connecting the suction surface 24 and the connecting surface 25 and the first end 21 can be designed to satisfy 0.7≤S / L≤0.9, so as to reduce wind resistance and reduce airflow flow loss.

[0044] According to the air guide plate assembly 1 for air conditioning equipment of this utility model, the shape of the first air guide blade 20 and the spacing between adjacent first air guide blades 20 are designed to ensure that the first air guide blade 20 has the guiding effect on airflow while reducing the resistance of the first air guide blade 20 to airflow and the influence on airflow flow, thereby reducing wind resistance and reducing airflow loss.

[0045] In some embodiments, reference may be made to Figure 6 , Figure 6 The projection of the first guide vane 20 in the second direction, in Figure 6 In the first guide vane 20, the first end 21 is approximately circular. The distance L between the edge where the pressure surface 23 and the connecting surface 25 are connected and the first end 21 can refer to the distance between the edge where the pressure surface 23 and the connecting surface 25 are connected and the center of the first end 21. Similarly, the distance S between the edge where the suction surface 24 and the connecting surface 25 are connected and the first end 21 can refer to the distance between the edge where the suction surface 24 and the connecting surface 25 are connected and the center of the first end 21.

[0046] Furthermore, by optimizing the D / G ratio, the vortex frequency in the wake region of the first guide vane 20 can be controlled between 20Hz and 30Hz, reducing the resonance between the first guide vane 20 and the fan rotation frequency of the air conditioning equipment, thus reducing the energy consumption of the air conditioning equipment motor. Combined with overall wind resistance optimization measures, the overall energy consumption is reduced by approximately 8% to 12%. Combined with the dynamic adjustment function, the air volume can be adjusted in real time according to the actual load, preventing the air conditioning equipment from over-cooling / heating.

[0047] In some embodiments, the spacing between two adjacent first guide vanes 20 is in the range of 10mm to 15mm.

[0048] According to some embodiments of this utility model, in the direction from the first end 21 to the second end 22, the radius of curvature of any point on the pressure surface 23 is R1, the radius of curvature of any point on the suction surface 24 is R2, and the maximum distance between the first end 21 and the second end 22 is L0, satisfying: 0.3≤R1 / L0≤0.4, and 0.3≤R2 / L0≤0.4. Specifically, the first end 21 is located upstream in the direction of airflow, and the second end 22 is located downstream in the direction of airflow. The radius of curvature R1 of the pressure surface 23 is the radius of any point on the circle containing the arc of the curved portion of the pressure surface 23, while the radius of curvature R2 of the suction surface 24 is the radius of any point on the circle containing the arc of the curved portion of the suction surface 24. The maximum distance L0 between the first end 21 and the second end 22 is the chord length of the first guide vane 20. It is understood that the radius of curvature should not be too small, and the maximum distance between the first end 21 and the second end 22 should not be too large, to avoid the first guide vane 20 affecting the airflow through the airflow channel, thus avoiding affecting the airflow rate. Conversely, the radius of curvature should not be too large, and the maximum distance between the first end 21 and the second end 22 should not be too small, to ensure that the first guide vane 20 has a guiding effect on the airflow. Therefore, the radius of curvature and the maximum distance L0 between the first end 21 and the second end 22 must simultaneously satisfy 0.3≤R1 / L0≤0.4 and 0.3≤R2 / L0≤0.4, to ensure that the first guide vane 20 has a guiding effect on the airflow while avoiding affecting the airflow rate.

[0049] Furthermore, the first guide vane 20 can be aerodynamically optimized. The blade shape of the first guide vane 20 can be referenced to the flying fish line shape. The parts where the pressure surface 23 and the suction surface 24 are connected to the connecting surface 25 are designed as serrated guide lines to achieve the effect of sorting the wind field.

[0050] According to some embodiments of this utility model, the maximum thickness of the first end 21 in the thickness direction is D1, and the maximum thickness of the second end 22 in the thickness direction is D2, satisfying: 1.5≤D1 / D2≤2. That is, the leading edge thickness of the first guide vane 20 is D1, and the trailing edge thickness is D2. The difference between the maximum thickness of the first end 21 and the maximum thickness of the second end 22 should not be too large, as this would affect the airflow. Conversely, the difference between the maximum thickness of the first end 21 and the maximum thickness of the second end 22 should not be too small, as this would affect the guiding effect of the first guide vane 20 on the airflow. Therefore, the maximum thickness D1 of the first end 21 and the maximum thickness D2 of the second end 22 satisfying 1.5≤D1 / D2≤2 can ensure that the first guide vane 20 has a guiding effect on the airflow while avoiding affecting the airflow.

[0051] According to some embodiments of this utility model, such as Figure 3 As shown, the frame 10 includes a frame body 11 and a second guide vane 12. The frame body 11 defines an installation space. The first guide vane 20 is located in the installation space and its two ends in a second direction are respectively connected to the frame body 11. The second direction intersects with the first direction. The second guide vane 12 is located in the installation space and extends in the first direction. The second guide vane 12 is connected to a plurality of first guide vanes 20, and its two ends in the extending direction are respectively connected to the frame body 11. Specifically, the frame body 11 can be used to install the guide vane assembly 1 as a whole in the air conditioning equipment. The air guide plate assembly 1 has a first air guide blade 20 and a second air guide blade 12. Both the first air guide blade 20 and the second air guide blade 12 are used to guide the airflow. The first air guide blade 20 and the second air guide blade 12 work together to form a local airflow closed loop, prolonging the contact time between the airflow and the heat exchanger of the air conditioning equipment, reducing ineffective circulation, thereby improving the heat exchange efficiency and comfort of the air conditioning equipment. In addition, the first air guide blade 20 and the second air guide blade 12 can guide the airflow to flow in different directions. The first air guide blade 20 and the second air guide blade 12 can disperse the airflow direction through multi-angle air delivery, making the airflow coverage area larger, avoiding excessive local temperature difference, and achieving uniform temperature field distribution.

[0052] In some embodiments, the first guide vane 20 is rotatably disposed on the second guide vane 12, and the rotation angle of the first guide vane 20 can be adjusted by a motor or manually, with an adjustment range of 0° to 90°. By dynamically adjusting the air delivery angle, the air conditioning device can direct the airflow channel between two adjacent first guide vanes 20 toward the area where people are active when heating, so as to push hot air to the area where people are active; while the air conditioning device can direct the airflow channel between two adjacent first guide vanes 20 toward the top of the room when cooling, so as to achieve horizontal air delivery and avoid cold air blowing directly on people, thereby enabling the air conditioning device to adapt to different operating conditions and make up for the efficiency loss caused by hot air being suspended at the top of the room when heating.

[0053] Furthermore, the air guide plate assembly 1 enables the first air guide blade 20 to rotate in the first direction, so that the air conditioning equipment equipped with the air guide plate assembly 1 can be arranged to discharge air in the first direction.

[0054] In some embodiments, the surfaces of the first guide vane 20 and / or the second guide vane 12 are designed with a noise-reducing coating, and the upstream ends of the first guide vane 20 and / or the second guide vane 12 in the airflow direction are designed with arc-shaped edges to reduce airflow shedding, suppress eddy current generation, and weaken airflow friction noise. Furthermore, a sound-absorbing cotton layer can be provided on the inner wall of the frame body 11 defining the installation space to absorb high-frequency noise and reduce airflow noise flowing through the guide vane assembly 1. See also Figure 8 The eddy current energy on the surface of the second guide vane 12 is less than 5 J / kg. By employing the above-mentioned composite noise reduction technologies, the noise generated by the guide vane assembly 1 during use can be reduced, thus improving the user experience.

[0055] According to some embodiments of this utility model, such as Figure 2 As shown, the second guide vanes 12 are configured as multiple second guide vanes spaced apart in the second direction. At this time, the multiple second guide vanes 12 are spaced apart in the extension direction of the first guide vane 20 to stably connect the first guide vane 20 to the frame body 11. Each second guide vane 12 can also guide the airflow and enhance the air guiding effect of the guide plate assembly 1.

[0056] According to some embodiments of this utility model, such as Figure 4As shown, the first guide vane 20 has a first end 21 and a second end 22 at its two ends in the third direction, which intersects with the second and first directions respectively. The second guide vane 12 has a third end 121 at one end in the third direction and a fourth end 122 at the other end, with the third end 121 connected to the first end 21 of the first guide vane 20. Specifically, since the third direction is consistent with the airflow direction, the first guide vane 20 can be located upstream of the second guide vane 12 in the airflow direction. In this case, the first end 21 of the first guide vane 20 is upstream of the third end 121 of the second guide vane 12. Therefore, the first guide vane 20 and the second guide vane 12 can guide the airflow in different directions, achieving multi-angle air delivery, dispersing the airflow direction, increasing the airflow coverage area, avoiding excessive local temperature differences, and achieving a uniform temperature field distribution.

[0057] According to some embodiments of this utility model, such as Figure 5 As shown, in the second direction, at least a portion of the thickness of the second guide vane 12 gradually decreases in the direction from the fourth end 122 to the third end 121, and / or, in the second direction, at least a portion of the thickness of the second guide vane 12 gradually decreases in the direction from the third end 121 to the fourth end 122. Specifically, the gradual decrease in the thickness of at least a portion of the second guide vane 12 can form an airflow guiding surface, reducing return air resistance. The second guide vane 12 can form an isolation zone between airflows, effectively isolating the supply and return air areas and reducing the risk of airflow short-circuiting. For example, in a side-supply, side-return layout, the second guide vane 12 can extend the airflow path, preventing hot air from directly returning and improving heating efficiency.

[0058] According to some embodiments of this utility model, such as Figure 5 As shown, the third end 121 has a first surface 1211 and a second surface 1212 disposed opposite to each other in the second direction, and the fourth end 122 has a third surface 1221 and a fourth surface 1222 disposed opposite to each other in the second direction. The first surface 1211 and the third surface 1221 are located on the same side of the second guide vane 12 in the second direction and are connected to each other, and the second surface 1212 and the fourth surface 1222 are located on the other side of the second guide vane 12 in the second direction and are connected to each other; wherein the ends of the first surface 1211 and the second surface 1212 away from the fourth end 122 are inclined toward each other; and / or the ends of the third surface 1221 and the fourth surface 1222 away from the third end 121 are inclined toward each other. In some embodiments, reference can be made to... Figure 5The first surface 1211 and the second surface 1212 of the second guide vane 12 are inclined toward each other at the ends away from the fourth end 122, and the ends of the third surface 1221 and the fourth surface 1222 are also inclined toward each other at the ends away from the third end 121, so that the cross-section of the second guide vane 12 in the first direction is approximately rhomboid, which plays a role in guiding the airflow.

[0059] According to some embodiments of this utility model, such as Figure 5 As shown, the third end 121 has a first surface 1211 and a second surface 1212 disposed opposite to each other in the second direction. The end of the first surface 1211 away from the fourth end 122 is inclined toward the second surface 1212 and the angle between the first surface 1211 and the second surface 1212 is α, and / or the end of the second surface 1212 away from the fourth end 122 is inclined toward the first surface 1211 and the angle between the second surface 1212 and the second surface 1212 is α, where α ranges from 15° to 30°. That is, the second guide vane 12 has a gradually decreasing slope at its upstream third end 121 in the airflow direction. This slope can be formed by the first surface 1211, or by the second surface 1212, or as shown in the diagram. Figure 5 As shown, the inclined surface is composed of a first surface 1211 and a second surface 1212, and the angle α of the inclined surface relative to the third direction ranges from 15° to 30° to reduce airflow resistance and guide airflow.

[0060] The air conditioning device according to this utility model is briefly described below.

[0061] The air conditioning device according to this utility model includes the air guide plate assembly 1 for air conditioning device described in any of the above embodiments. Since the air conditioning device according to this utility model is provided with the air guide plate assembly 1 for air conditioning device described in the above embodiments, the user experience of the air conditioning device is better.

[0062] Here, the air conditioning equipment can be in various indoor unit forms such as ducted units and embedded units (e.g., side supply bottom return, side supply side return), and is compatible with expansion components such as static pressure boxes, which can meet the needs of different building structures, have better compatibility, and adapt to the diversity of multi-split systems.

[0063] In summary, the shape of the first guide vane 20 and the spacing between adjacent first guide vanes 20 are designed according to the air guide plate assembly 1 for air conditioning equipment of this utility model, so as to ensure that the first guide vane 20 has the guiding effect on airflow while reducing the resistance of the first guide vane 20 to airflow and the influence on airflow flow, thereby reducing wind resistance and reducing airflow loss.
