[0044] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0047] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] like Figure 1 As shown, an embodiment of the utility model provides an air outlet mesh cover 100, including a center plate 1, an outer frame 2 arranged outside the center plate 1, and a grille structure connected between the center plate 1 and the outer frame 2, the grille structure including a plurality of annular ribs 34 radially spaced apart along the center plate 1, and a plurality of main ribs 31 circumferentially spaced apart along the center plate 1; a plurality of annular ribs 34 and a plurality of radiating ribs are arranged between any two adjacent main ribs 31, and the radiating ribs and the main ribs 31 extend in an arc along the radial direction of the center plate 1; the minimum width of the main ribs 31 along the radial direction of the center plate 1 is greater than the width of the radiating ribs along the radial direction of the center plate 1.

[0049] The air outlet mesh cover 100 is provided with main ribs 31, and the minimum width of the main ribs 31 along the radial direction of the center plate 1 is limited to be greater than the width of the radial ribs along the radial direction of the center plate 1, so as to enhance the structural strength of the air outlet mesh cover 100. As a result, when designing the air outlet mesh cover 100, the number of annular ribs 34 can be reduced, thereby reducing the grid density of the grille, thereby reducing the air outlet resistance of the air outlet mesh cover 100 and reducing the noise of the air outlet mesh cover 100.

[0050] At the same time, by limiting the minimum width of the main ribs 31 along the radial direction of the center plate 1 to be greater than the width of the radial ribs along the radial direction of the center plate 1 , the identification of the air outlet grille 100 can also be improved.

[0051] In addition, the radial ribs and the main ribs 31 extend in an arc along the radial direction of the center plate 1, so that the radial ribs and the main ribs 31 fit the arc of the rotation direction of the wind wheel blades, thereby reducing the wind resistance of the air outlet mesh cover 100 and lowering the air outlet noise.

[0052] In some embodiments, the radial spacing between two adjacent annular ribs 34, the radial spacing between the center plate 1 and the adjacent annular rib 34, and the radial spacing between the outer frame 2 and the adjacent annular rib 34 are 60 mm to 70 mm. Such an arrangement and the structure of the main rib 31 can reduce the density of the grid while ensuring the structural strength of the air outlet mesh cover 100.

[0053] In some embodiments, Figure 1As shown, from the center plate 1 to the outer frame 2, the width of the main rib 31 along the circumference of the center plate 1 gradually increases, avoiding the grid distribution of the grille near the center plate 1 being too dense and reducing the air outlet near the center plate 1, thereby ensuring smooth air outlet near the center plate 1.

[0054] In some embodiments, from the center plate 1 to the outer frame 2 , the widths of the main ribs 31 along the circumference of the center plate 1 are equal.

[0055] In some embodiments, the plurality of radiating ribs include a plurality of first radiating ribs 32 and a plurality of second radiating ribs 33, wherein one end of the first radiating rib 32 is connected to the center plate 1, and the other end is connected to the annular rib 34 closest to the center plate 1; one end of the second radiating rib 33 is connected to the annular rib 34 closest to the center plate 1, and the other end is connected to the outer frame 2; the number of the first radiating ribs 32 is less than the number of the second radiating ribs 33.

[0056] Such an arrangement can avoid the radiation ribs around the center plate 1 being too dense to increase the wind resistance and noise, ensure the air volume around the center plate 1, and reduce the wind resistance and noise around the center plate 1.

[0057] In some embodiments, Figure 1 As shown, multiple annular ribs 34 are coaxially arranged with the center plate 1. From the air inlet side to the air outlet side, multiple annular ribs 34 are arranged in sequence, so that the air outlet mesh cover 100 can be roughly formed into an arch structure, thereby enhancing the supporting capacity of the air outlet mesh cover 100, making the air outlet mesh cover 100 not easy to be damaged, and improving the applicability of the air outlet mesh cover 100.

[0058] In some embodiments, the main rib 31 is formed by injection molding. During the injection molding process, due to process limitations, a process groove 311 extending along the main rib 31 is formed. The main rib 31 has an air inlet side and an air outlet side that are arranged opposite to each other along the axial direction of the center plate 1. In order to prevent the process groove 311 from being exposed and affecting the aesthetic effect of the air outlet grille 100, the process groove 311 is arranged on the air inlet side. The presence of the process groove 311 will cause the airflow to blow into the process groove 311 to generate turbulence and generate noise. For this reason, Figures 2 to 4 As shown, the process groove 311 is filled with a diverter 4, and the diverter 4 is arranged protruding from the open end surface of the process groove 311. When the airflow flows near the main rib 31, the diverter 4 diverts the airflow to both sides of the main rib 31, and blows out smoothly, which can effectively reduce the wind noise.

[0059] In some embodiments, the diverter 4 is a sound-absorbing structure, such as a sponge strip, a foam strip, etc. When the airflow hits the diverter 4, part of it is directed to both sides of the main rib 31, and the other part enters the diverter 4 and is absorbed by the sound-absorbing structure to reduce noise.

[0060] In some embodiments, the flow divider 4 has a flow divider end face facing away from the bottom wall of the process groove 311, and two flow divider side faces arranged opposite to each other along the circumference of the center plate 1, and the flow divider end face and the flow divider side faces are smoothly connected through rounded corners. In this way, the airflow can be divided to both sides of the main rib 31, so that the airflow smoothly bypasses the flow divider 4 and the main rib 31, reducing noise.

[0061] In some embodiments, Figure 4 As shown, the flow divider 4 is glued and fixed to the inner wall of the process groove 311. Specifically, the flow divider 4 is glued and fixed to the bottom wall of the process groove 311 by a rubber strip facing the bottom surface of the process groove 311, and the fixing method is simple and the installation is quick.

[0062] Since the circumferential width of the main rib 31 near the center plate 1 is small, the spacing between the two opposite side walls of the process groove 311 along the circumference of the center plate 1 is particularly small, which makes it inconvenient to fill the diverter 4, and the air volume near the center plate 1 is small. Therefore, the process groove 311 near the center plate 1 has little effect on the air volume. For this reason, in some embodiments, such as Figure 2 As shown, the flow divider 4 is arranged between the annular rib 34 closest to the center plate 1 and the outer frame 2 .

[0063] In some embodiments, Figures 5 to 7 As shown, the utility model further provides an outdoor unit panel, including a panel body 200 and the above-mentioned air outlet mesh cover 100 . The panel body 200 is provided with a mounting hole 203 , and the air outlet mesh cover 100 is mounted in the mounting hole 203 .

[0064] The outdoor unit panel is the air outlet panel of the air-conditioning outdoor unit. When the above-mentioned air outlet mesh cover 100 is applied to the outdoor unit panel, it can reduce the air outlet wind resistance of the air-conditioning outdoor unit, reduce the operating noise of the air-conditioning outdoor unit, and improve the user experience effect; at the same time, it is also beneficial to increase the air outlet volume of the air-conditioning outdoor unit, ensure the wind wheel efficiency of the air-conditioning outdoor unit, and thus ensure the heat exchange efficiency of the air-conditioning outdoor unit.

[0065] In some embodiments, Figures 7 to 12 As shown, the outer frame 2 and the panel body 200 can be connected by a snap-fit ​​structure or by fasteners. In a preferred embodiment, as shown in FIG. Figures 8 to 10 As shown, the outer frame 2 is snapped with the panel body 200 through a plurality of snap structures arranged at intervals in the circumferential direction, and the outer frame 2 and the panel body 200 are connected by fasteners. For example, there is one fastener such as a screw. In this way, the air outlet grille 100 and the panel body 200 can be connected while reducing the number of fasteners used, thereby improving the aesthetics of the outdoor unit panel.

[0066] In some embodiments, Figures 7 to 10As shown, the snap-on structure includes a snap-on 23 with one end connected to the outer frame 2, a snap-on hole 202 is provided on the panel body 200, and the other end of the snap-on 23 passes through the snap-on hole 202 and abuts against one side of the thickness direction of the panel body 200 along the axial direction of the center plate 1 to snap the outer frame 2 and the panel body 200 together.

[0067] Specifically, after the buckle 23 passes through the buckle hole 202, the air outlet grille 100 can rotate circumferentially relative to the panel body 200, so that the buckle 23 abuts against one side of the thickness direction of the panel body 200 along the axial direction of the center plate 1. In other embodiments, the buckle 23 can also adopt an undercut structure that can undergo elastic deformation, which is a prior art in the field and will not be described in detail here.

[0068] Exemplarily, an annular flange 22 is provided on the outer edge of the outer frame 2, and the buckle 23 and the protrusion 21 are both provided on the annular flange 22; an annular groove 201 is provided on the panel body 200, and the clamping hole 202 is provided on the bottom wall of the annular groove 201, and the annular flange 22 is inserted into the annular groove 201 along the axial direction of the center plate 1.

[0069] When installing the air outlet mesh cover 100 on the panel body 200, insert multiple clips 23 into the corresponding clip holes 202 one by one. After the clips 23 pass through the clip holes 202, rotate the air outlet mesh cover 100 so that the clips 23 abut against one side of the panel body 200 in the thickness direction, and then fix the panel body 200 and the air outlet mesh cover 100 with a fastener. The installation of the air outlet mesh cover 100 is simple and quick.

[0070] In some embodiments, Fig.11 and Fig.12 As shown, a convex portion 21 is sandwiched between the outer frame 2 and one side of the panel body 200 in the thickness direction, and a plurality of convex portions 21 are provided, and the plurality of convex portions 21 are arranged at intervals along the circumference of the outer frame 2. Exemplarily, one convex portion 21 is arranged between any two adjacent buckle structures, and the convex portion 21 is a frustum structure, and the small diameter end of the frustum structure abuts against the panel body 200, and the panel body 200 is sandwiched between the buckle 23 and the convex portion 21.

[0071] Such an arrangement can make the panel body 200 and the air outlet grille 100 fit more tightly, thereby reducing the generation of vibration noise.

[0072] In some embodiments, the protrusion 21 and the outer frame 2 are integrally formed, and the forming method is simple and low in cost.

[0073] In some embodiments, Figure 1 and Fig.11As shown, a countersunk groove 24 is provided on the outer side of the outer frame 2, a through hole 25 is provided on the bottom wall of the countersunk groove 24, and a threaded countersunk hole 204 is provided on the panel body 200. A fastener such as a screw passes through the through hole 25 and is threadedly connected to the threaded countersunk hole 204, and the head of the screw does not extend out of the countersunk groove 24. Such a configuration can prevent the fastener from being exposed and affecting the aesthetics of the outdoor unit panel.

[0074] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
