[0047] The invention provides an air outlet component.

[0048] Reference Figures 1 to 6 In an embodiment of the present invention, the air outlet assembly includes a panel body 10 and a guide ring 20, the panel body 10 is provided with an air outlet 11; the guide ring 20 is arranged on the panel body 10, and the guide ring 20 includes a main air ring 21 and an air expansion portion 22, the main air ring 21 is coaxially arranged with the air outlet 11, the air expansion portion 22 is located on the air outlet side of the main air ring 21, and one end is connected to the main air ring 21, and the other end extends in a direction away from the main air ring 21, so that the outlet airflow is diffused along the air expansion portion 22, thereby being able to achieve a significant reduction in noise value at the same air volume and an increase in air volume at the same noise.

[0049] The main wind circle 21 is arranged around the air outlet 11 to facilitate guiding the outlet airflow to the external environment. An air expansion portion 22 is arranged on the air outlet side of the main wind circle 21, and the air expansion portion 22 is arranged on the panel body 10. At this time, one end of the air expansion portion 22 can be connected to the side wall of the main wind circle 21, or connected to the periphery of the main wind circle 21, and the other end extends in the direction away from the main wind circle 21. In this way, the air outlet area of ​​the guide circle 20 can be increased, the wind speed can be reduced, the static pressure can be increased, and the airflow can be stabilized, the air supply distance can be increased, the noise can be reduced, the air output can be increased, and the user experience can be improved.

[0050] Specifically, the free end of the air expansion portion 22 extends in a direction away from the main air circle 21 and can serve as a diffusion channel, thereby increasing the air outlet area to a certain extent and being able to guide at least part of the air outlet air flow in a direction away from the main air circle 21. This helps to reduce the generation of vortices on the inner wall surface of the main air circle 21, reduce the loss of air outlet volume and reduce vortex noise. Therefore, under the condition of the same air volume, the noise in the axial direction of the main air circle 21 can be greatly reduced and the diffusion direction of the air outlet air flow can be changed; the air outlet volume can also be increased under the condition of the same noise.

[0051] In the technical solution of the present invention, the guide ring 20 is provided with an air expansion portion 22, which is connected to the main air ring 21 through the air expansion portion 22, and its free end extends in the direction away from the main air ring 21, so that the air expansion portion 22 serves as a diffusion channel, which increases the air outlet area to a certain extent, and can guide at least part of the air outlet air flow in the direction away from the main air ring 21, thereby helping to reduce the generation of vortices on the inner wall surface of the main air ring 21, reduce the loss of air outlet volume and reduce vortex noise. Therefore, under the condition of the same air volume, the noise in the axial direction of the main air ring 21 can be greatly reduced, and the diffusion direction of the air outlet air flow can be changed; the air outlet volume can also be increased under the condition of the same noise.

[0052] Reference Figure 1 In one embodiment, the air diffuser 22 is provided in plurality, and the plurality of air diffusers 22 are arranged at intervals around the axis of the main air circle 21. In this way, the air outlet area can be further increased by adding a plurality of air diffusers 22, i.e., a plurality of diffusion channels, while making reasonable use of the internal layout space of the outdoor unit 100 and avoiding internal parts, and most of the air flow is diffused in a direction away from the main air circle 21, thereby greatly reducing the noise in the axial direction of the main air circle 21 and reducing the loss of air volume, thereby achieving a significant reduction in noise value at the same air volume and an increase in air volume at the same noise. Two or more air diffusers 22 can be provided, such as Figure 1 As shown, four air expansion parts 22 are provided, and the four air expansion parts 22 are provided corresponding to the four corners of the panel body 10, which reasonably utilizes the layout space and can reliably avoid the internal parts of the outdoor unit 100 to ensure the normal air guidance of the air expansion part 22.

[0053] The plurality of air diffusers 22 are evenly spaced around the main air ring 21, so that the airflow from the main air ring 21 can be evenly dispersed, flows along each air diffuser 22 and diffuses to the external environment, effectively reducing the regionalized air volume concentration.

[0054] Specifically, in one embodiment, the air expansion portion 22 is configured as a spiral groove concavely arranged on the surface of the panel body 10. This is beneficial to improving the smoothness of airflow circulation. At the same time, since the air expansion portion 22 has a spiral structure, the outlet airflow can form a spiral airflow, thereby increasing the flow momentum, making it easier to push the remaining airflows to flow together, reducing airflow backflow, effectively increasing the air output, and reducing noise.

[0055] The connection between the air diffuser 22 and the main air ring 21 is smooth and continuous, which facilitates smoother air flow, reduces the occurrence of turbulence caused by an uneven connection, and can reduce noise and loss of air output.

[0056] Furthermore, in one embodiment, the contour line of the spiral groove constitutes a partial arc segment of the spiral line and satisfies the following equation: x=k*cosγ / γ, y=k*sinγ / γ, k is a constant, and γ is a polar angle.

[0057] Among them, x and y are the coordinate values ​​of any point on the spiral line. The contour line of the spiral groove is obtained by taking different values ​​of x and y. Since the contour line forms arc segments at different positions on the spiral line, the extension direction of the spiral groove can be changed, and then the direction of the airflow can be changed, which is conducive to improving the air volume and noise according to needs.

[0058] Combined with reference Figure 1 In one embodiment, the spiral groove includes a first extension segment and a second extension segment connected to each other, and the starting angle α1 between the extension direction of the first extension segment and the inner diameter extension direction of the main air circle 21 is smaller than the terminal angle α2 between the extension direction of the second extension segment and the inner diameter extension direction of the main air circle 21, so as to confirm the entry angle and exit angle of the airflow and improve the air outlet effect.

[0059] Specifically, one end of the first extension section smoothly transitions with the main wind circle 21, and the other end smoothly transitions with the second extension section, and the end of the second extension section away from the second extension section smoothly transitions with the surface of the panel body 10, so that the smooth flow of air can be ensured, and the air flow can flow along a relatively smooth and continuous surface during the flow process, thereby reducing the generation of turbulence and noise and improving the air outlet effect;

[0060] The first extension section and the second extension section are connected to form a spiral groove, wherein the contour line of the first extension section and the contour line of the second extension section are both curves, and can form a spiral contour line after being connected. Since there is a starting angle α1 between the extension direction of the first extension section and the inner diameter extension direction of the main wind circle 21, and there is a terminal angle α2 between the extension direction of the second extension section and the inner diameter extension direction of the main wind circle 21, and α1 is less than α2, that is, the air flow flowing out of the main wind circle 21 flows toward the first extension section, and diffuses toward the second extension section along the angle α1. After flowing into the second extension section, it diffuses toward the external environment along the angle α2. By setting α2 to be greater than α1 and smoothly connecting the main wind circle 21, the first extension section, the second extension section and the panel body 10, the air outlet area is increased step by step, the air outlet volume is effectively increased, the noise is reduced, and the air outlet direction is changed.

[0061] Furthermore, in one embodiment, the difference between the starting angle α1 and the terminal angle α2 satisfies: 10°<α2-α1<40°. Specifically, when α2-α1<10°, since the difference between the starting angle and the terminal angle is too small, a larger air outlet area cannot be obtained on the limited panel body 10, and the diffusion direction of the air outlet airflow cannot be changed significantly, and turbulence is likely to occur, thereby affecting the increase in air outlet volume and the reduction of noise in the axial direction of the main air circle 21; when α2-α1>40°, since the difference between the starting angle and the terminal angle is too large, it is easy to cause the air outlet airflow to diffuse excessively in the second extension section, causing the outlet airflow to diverge, affecting the air supply distance and the increase in air outlet volume. Therefore, the difference between the starting angle α1 and the terminal angle α2 is set between 10° and 40°, so as to obtain a larger air outlet area on the limited panel body 10. At the same time, the flow direction of the outlet air flow can be reliably changed to ensure the stable diffusion of the outlet air flow, reduce the reduction in air volume and increase in noise due to turbulence, and ensure the air supply distance of the outlet air flow.

[0062] The difference between the starting angle α1 and the terminal angle α2 may specifically be 15°, 20°, 25°, 30°, 35°, etc., which is not limited here.

[0063] Specifically, in one embodiment, the starting angle α1 satisfies: α1>25°, which can reliably change the airflow direction of the outlet airflow flowing out of the main air circle 21, and at the same time, avoid the starting angle being too small, α1<25°, which causes a sudden change in the airflow direction of the outlet airflow entering the air expansion part 22, so that the outlet airflow can be ensured to flow into the air expansion part 22 more smoothly, effectively reducing the generation of turbulence and noise. The specific value of the starting angle α1 can be 30°, 35°, 40°, 45°, 50°, etc., which is not limited here.

[0064] More specifically, in one embodiment, α1 = 35°, which facilitates guiding most of the outlet airflow to flow toward the air expansion portion 22, and the outlet airflow flows relatively smoothly.

[0065] Specifically, in one embodiment, the terminal angle α2 satisfies: α2>50°, which can reliably change the airflow direction of the airflow flowing out of the air diffuser 22, and at the same time, avoid the terminal angle being too small, α2<50°, which will result in a small airflow area, unclear diffusion direction, and easy to affect the air supply distance. In this way, it can ensure a large airflow area and a relatively obvious diffusion direction, thereby effectively reducing the generation of turbulence and reducing the noise in the axial direction of the main air circle 21. The specific value of the terminal angle α2 can be 55°, 60°, 65°, 70°, etc., which is not limited here.

[0066] More specifically, in one embodiment, α2 = 70°, which facilitates guiding the outlet airflow to the external environment and maintaining a relatively high air volume, thereby reducing the noise in the axial direction of the main air circle 21 .

[0067] Reference Figure 2 In one embodiment, a first contour line where a first cross section along the central axis of the main wind circle 21 intersects with the wind expansion portion 22 is an arc that protrudes away from the central axis of the main wind circle 21, and the arc has an air inlet end and an air outlet end, and an angle β1 between a tangent at the air inlet end and the central axis and an angle β2 between a tangent at the air outlet end and the central axis satisfy: β2<β1.

[0068] Specifically, the first contour line is an arc that protrudes away from the central axis of the main air circle 21. On the one hand, it can make the outlet air flow flow along a relatively smooth and continuous surface during the flow process, thereby reducing the generation of turbulence and noise. On the other hand, by setting the air inlet angle of the air inlet end and the air outlet angle of the air outlet end of the first contour line, that is, limiting β2<β1, the airflow is effectively guided to enter the air expansion part 22. At the same time, the diffusion direction of the outlet airflow is limited to ensure the stable diffusion of the outlet airflow, thereby increasing the air output, reducing noise, and improving the air supply distance.

[0069] Furthermore, in one embodiment, the angle β1 between the tangent of the air inlet end and the central axis satisfies: 20°<β1<60°, that is, the specific value of the angle β1 can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, etc.; and / or, the angle β2 between the tangent of the air outlet end and the central axis satisfies: 20°<β2<60°, that is, the specific value of the angle β2 can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, etc.; wherein, the limitation of β2<β1 is more conducive to improving the air outlet effect.

[0070] Reference Figure 2In one embodiment, the main air circle 21 includes an air inlet section 211, a connecting section 212 and an air outlet section 213 which are connected in sequence. The inner wall of the connecting section 212 is a cylindrical surface, and the inner wall of the air outlet section 213 is an arc-shaped surface that bends and extends outward. The air expansion portion 22 is connected to the air outlet section 213. Then, the airflow enters the connecting section 212 from the air inlet section 211. Since the inner wall of the connecting section 212 is a cylindrical surface, the airflow flowing in from the air inlet section 211 can be better gathered, and the gathered airflow can be guided to the air outlet section 213. Each air expansion portion 22 is connected to a portion of the air outlet section 213, and the inner wall of the air outlet section 213 is an arc-shaped surface that bends and extends outward. On the one hand, the air expansion portion 22 and the air outlet section 213 can be transitioned more smoothly, ensuring the smoothness and stability of the flow of the airflow flowing to the air expansion portion 22. At the same time, the air outlet area is further expanded and the diffusion of the airflow is reliably guided. On the other hand, the flow direction of the airflow flowing through the air outlet section 213 is effectively changed. Such a setting can effectively reduce the noise in the axial direction of the main air circle 21 to a certain extent and increase the air output.

[0071] In addition, the inner wall of the air inlet section 211 is an arc-shaped surface that bends and extends outwards, so as to better collect the generated airflow and increase the air output.

[0072] Specifically, in one embodiment, the thickness of the connecting section 212 is H1, 25mm≤H1≤60mm, and the height of the connecting section 212 along the axis of the main air circle 21 is reasonably set to ensure that the connecting section 212 has a gathering and guiding effect on the airflow, thereby reducing the generation of vortices on the inner wall of the main air circle 21, reducing the loss of air volume, and reducing noise. Among them, the specific value of the thickness H1 of the connecting section 212 can be 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc., which is not limited here.

[0073] Specifically, in one embodiment, the thickness of the air outlet section 213 is H2, 15mm≤H2≤50mm. By reasonably setting the height of the air outlet section 213 along the axis of the main air circle 21, the height of the air expansion section 22 along the axis of the main air circle 21 on the panel body 10, as well as the starting angle and terminal angle of the air expansion section 22 can be further set, and then the extension direction and diffusion direction of the air expansion section 22 can be reasonably set to ensure the increase of air volume and the reduction of noise. Among them, the specific value of the thickness H2 of the air outlet section 213 can be 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc., which is not limited here.

[0074] In order to further improve the air volume and air effect, refer to Figures 3 to 6In one embodiment, the air outlet component also includes an air outlet mesh cover 30, and the air outlet mesh cover 30 is arranged at the air outlet end of the panel body 10. The air outlet mesh cover 30 has a main air outlet area 31 corresponding to the main air circle 21, and an air expansion area 32 corresponding to the air expansion part 22, so as to conform to the airflow direction of the outlet air flow, thereby effectively reducing the possibility of the airflow and the air outlet mesh cover 30 impacting each other, effectively increasing the air output and reducing noise.

[0075] The air outlet mesh cover 30 and the panel body 10 can be an integrated structure or a split structure. The main air outlet area 31 on the air outlet hood is set correspondingly to the main air circle 21 to conform to the air flow direction from the main air circle 21 to the air outlet mesh cover 30. The air expansion part 22 is set correspondingly to the air expansion area 32 to conform to the air flow direction from the air expansion part 22 to the air outlet mesh cover 30. The two phases are coordinated to reduce resistance, prevent each air flow from impacting the air outlet mesh cover 30, effectively reduce air flow loss and turbulence, and thus increase the air volume and reduce noise to a certain extent. At the same time, the air outlet mesh cover 30 can also protect the outdoor unit 100 to prevent foreign objects from entering the outdoor unit 100 and affecting the normal operation of the air conditioner outdoor unit 100.

[0076] Reference Figure 3 In one embodiment, the air outlet mesh cover 30 includes a central disk 33, a rib group 34 and an outer frame 35 which are arranged in sequence from the inside to the outside; the rib group 34 includes a plurality of first radiating ribs 341 and a plurality of second radiating ribs 342, the plurality of first radiating ribs 341 are arranged along the circumference of the central disk 33 to form the air expansion area 32, the plurality of second radiating ribs 342 are arranged along the circumference of the central disk 33 to form the main air outlet area 31, the inclination direction of the first radiating rib 341 and the second radiating rib 342 are arranged along the circumference of the central disk 33 to form the main air outlet area 31, and the inclination direction of the first radiating rib 341 and the second radiating rib 342 are arranged along the circumference of the central disk 33 to form the main air outlet area 31. The inclination direction of the radiating ribs 342 is set to conform to the airflow direction of the corresponding airflow. It can be understood that along the extension direction of the first radiating ribs 341, the first radiating ribs 341 are inclined to conform to the airflow direction of the airflow flowing from the air expansion part 22 to the air expansion area 32, and along the extension direction of the second radiating ribs 342, the second radiating ribs 342 are inclined to conform to the airflow direction of the airflow flowing from the main air circle 21 to the main air outlet area 31. In this way, the obstruction to the airflow and the generation of turbulence can be effectively reduced, thereby facilitating the increase of air output and the reduction of noise.

[0077] Specifically, each first radiating rib 341 can be arranged on the outside of each second radiating rib 342, or, by replacing the second radiating rib 342 of the corresponding air expansion part 22, the radiating ribs of the corresponding air expansion part 22 are all first radiating ribs 341, and then, by conforming to the flow direction of the airflow, the resistance to the airflow is reduced, and the possibility of turbulence is reduced, thereby increasing the air output and reducing noise.

[0078] In addition, the air outlet mesh cover 30 also includes a plurality of annular ribs, each of which is spaced and nested in sequence and is arranged concentrically with the center disk 33. The annular ribs are located between the center disk 33 and the outer frame 35, and intersect and connect with the first radial ribs 341 and the second radial ribs 342 to enhance the structural strength and stability of the air outlet mesh cover 30.

[0079] Reference Figures 3 to 5 In one embodiment, a first inclination angle θ1 is formed between the first radiation rib 341 and the reference surface, a second inclination angle θ2 is formed between the second radiation rib 342 and the reference surface, and θ1≤θ2, the reference surface is perpendicular to the center line of the center disk 33, and by setting θ1≤θ2, the outlet airflow passing through the main wind circle 21 flows through the second radiation rib 342, and then flows to the external environment, and the outlet airflow passing through the air expansion part 22 flows through the first radiation rib 341, and then flows to the external environment, thereby increasing the air outlet area to a certain extent, and at the same time, avoiding excessive escape of airflow and airflow loss, thereby ensuring the stable diffusion of the airflow, which is beneficial to increasing the air volume, reducing noise, and facilitating increasing the air supply distance of the airflow.

[0080] Reference Figure 4 In one embodiment, 45°<θ1<80°, which can reliably conform to the flow direction of the airflow flowing to the air outlet mesh cover 30 under the action of the air expansion part 22. When θ1 is greater than 80° or less than 45°, the airflow is easily impacted by the first radiation rib 341, resulting in airflow loss and turbulence. Therefore, by setting θ1 between 45° and 80°, it is helpful to reduce resistance, prevent the airflow from impacting the first radiation rib 341, effectively reduce airflow loss and turbulence, and thus increase the air volume and reduce noise to a certain extent. Specifically, the specific value of the first inclination angle θ1 can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, etc., which is not limited here.

[0081] Reference Figure 5 In one embodiment, 55°<θ2<75°, which can reliably conform to the flow direction of the outlet airflow flowing to the outlet mesh cover 30 under the action of the main wind circle 21. When θ2 is greater than 75° or less than 55°, the outlet airflow is prone to impact with the second radiation rib 342, resulting in airflow loss and turbulence. Therefore, by setting θ2 between 545° and 75°, it is helpful to reduce resistance, prevent the outlet airflow from impacting the first and second radiation ribs, effectively reduce airflow loss and turbulence, and thus increase the air volume and reduce noise to a certain extent. Specifically, the specific value of the second inclination angle θ2 can be 55°, 60°, 65°, 70°, 75°, etc., which is not limited here.

[0082] More specifically, in one embodiment, θ1=65°, which is convenient for guiding most of the outlet airflow to flow through the first radiation rib 341, and the outlet airflow flows relatively smoothly. In one embodiment, θ2=70°, which is convenient for guiding most of the outlet airflow to flow through the second radiation rib 342, and the outlet airflow flows relatively smoothly.
