[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] In the related art, the outdoor unit of the air conditioner includes an air outlet grille. To ensure smooth air outlet, the air outlet grille is usually constructed as a grille structure. Most grille structures use multiple concentric circular bars with gradually increasing diameters that are arranged radially from the inside to the outside. Along the arrangement direction of the multiple bars, the spacing between every two adjacent bars is basically equal. When the airflow passes through such an air outlet grille, it is easy to diffuse to both sides along the extension direction of the bars, resulting in unstable air outlet, short air supply distance, and the airflow diverging to both sides will produce large aerodynamic noise. In addition, when the airflow flows through the concentric circular air outlet grille, it is easy to split and generate air vortices, which will cause pressure fluctuations at the air outlet grille, and then cause the pulsation of the air outlet grille to produce noise interference.

[0042] Based on this, refer to Figure 1 As shown, the embodiment of the utility model provides an air outlet mesh cover 1000, which is applied to an outdoor unit of an air conditioner. The air outlet mesh cover 1000 is located at the air outlet of the outdoor unit of the air conditioner, and the air flow will pass through the air outlet mesh cover 1000. The air outlet mesh cover 1000 includes a frame 100 and an air outlet grille 101. The air outlet grille 101 is located on the inner side of the frame 100. The air flow will pass through the air outlet grille 101. The air outlet grille 101 includes a plurality of grille groups. Figure 3 As shown, each grid group includes a first grid bar 102, a second grid bar 103 and a third grid bar 104. In some embodiments, the first grid bar 102, the second grid bar 103 and the third grid bar 104 can be of the same structure, and the first grid bar 102, the second grid bar 103 and the third grid bar 104 are parallel to each other, the second grid bar 103 is located between the first grid bar 102 and the third grid bar 104, the first grid bar 102 and the third grid bar 104 are respectively located on opposite sides of the second grid bar 103, the first grid bar 102 is adjacent to the second grid bar 103, and the third grid bar 104 is adjacent to the second grid bar 103.

[0043] It should be noted that since the structures of the first grid bar 102, the second grid bar 103 and the third grid bar 104 are roughly the same, in the following embodiments, some descriptions will refer to the first grid bar 102, the second grid bar 103 and the third grid bar 104 as grid bars, and the grid bar refers to any one of the first grid bar 102, the second grid bar 103 and the third grid bar 104.

[0044] Specifically, refer to Figure 3 and Figure 5 As shown, the spacing between the first grid bar 102 and the second grid bar 103 is L1, and the spacing between the second grid bar 103 and the third grid bar 104 is L2, and L1 is smaller than L2. L1 can be understood as the minimum spacing between the first grid bar 102 and the second grid bar 103, and L2 can be understood as the minimum spacing between the second grid bar 103 and the third grid bar 104.

[0045] In this embodiment, by setting the spacing between the first grille bar 102 and the second grille bar 103 to be smaller than the spacing between the second grille bar 103 and the third grille bar 104, it can also be understood that along the arrangement direction of the multiple grille groups, the spacing between each two adjacent grille bars is variable, for example, the spacing values ​​are arranged like L1, L2, L1, L2, and the spacing between two adjacent grille bars can be understood as the air outlet channel 109. Along the arrangement direction of the multiple grille groups, the widths of any two adjacent air outlet channels 109 are different. L2 can be understood as a large spacing, L1 can be understood as a small spacing, and multiple small spacings and multiple large spacings are alternately arranged along the arrangement direction of the multiple grille groups. When the airflow passes through the above-mentioned intervals, the intervals will change the flow direction or flow state of the airflow. Specifically, a large part of the airflow mainly passes through the interval L2, and a small part of the airflow passes through the two intervals L1. When most of the airflow passes through the interval L2, since the interval L2 is large, most of the airflow will expand and the wind resistance can be reduced. When a small part of the airflow passes through the interval L1, since the interval L1 is small, the small part of the airflow can be compressed to prevent self-disturbance or mutual disturbance of the air. Since the two intervals L1 are respectively arranged on both sides of the interval L2, it can be understood that a small part of the compressed airflow is sandwiched on both sides of the majority of the airflow that is expanding, so that the edge of the airflow is not easy to diffuse to both sides, so that the overall airflow is more concentrated, which plays a role in gathering wind and allows the airflow to gather in the middle of the air outlet mesh cover 1000, thereby improving the airflow efficiency and stability and reducing the aerodynamic noise caused by the diffusion of the airflow to both sides.

[0046] Reference Figure 1 As shown, the air outlet grille 1000 includes an air outlet area 110 and a closed area 111. The closed area 111 surrounds the outer periphery of the air outlet area 110. The air outlet area 110 corresponds to the position of the air outlet of the air conditioner outdoor unit. The air outlet area 110 is used to provide normal air outlet for the air flow. The closed area 111 is located outside the air outlet of the air conditioner outdoor unit. The air flow cannot pass through the closed area 111. The closed area 111 is a solid structure, which can enhance the structural strength of the air outlet grille 1000. The air outlet grille 101 can be located in the air outlet area 110, or it can span the air outlet area 110 and the closed area 111.

[0047] Reference Figure 1As shown, in some embodiments, the air outlet mesh cover 1000 is square as a whole, and the air outlet area 110 is roughly circular, so that the air outlet area 110 matches the shape of the fan blades inside the air conditioner outdoor unit, and the closed area 111 can be understood as the remaining area after subtracting the circular area from the square area.

[0048] It is understandable that in some embodiments, the ratio of L2 and L1 satisfies: 1.3≤L2 / L1≤2.5. It should be noted that, according to simulation experiments, if the ratio of L2 and L1 is less than 1.3, the air flow is always in a compressed state, the wind resistance is large, and the noise is easily increased. If the ratio is greater than 2.5, most of the air flow molecules are in an expanded state, resulting in self-disturbance or mutual interference of the air flow, and it is not easy to dissipate heat outward. In this embodiment, through comprehensive consideration, the ratio of L2 and L1 is between 1.3 and 2.5, ensuring a better wind gathering effect, more concentrated air outlet, longer air supply distance, avoiding hot air backflow, and ensuring strong cooling capacity.

[0049] It should be noted that, refer to Figure 2 and Figure 6 As shown, the air outlet grille 1000 has a front side and a rear side, and the air outlet grille 1000 has an air outlet direction. The airflow passes through the air outlet grille 1000 from back to front, and the air outlet direction can be understood as a direction from back to front. Figure 5 As shown, in some embodiments, the air outlet mesh cover 1000 includes a plate body portion 200, which is located in the closed area 111. The plate body portion 200 can be understood as a solid flat plate structure, and the plate body portion 200 has a front side surface and a rear side surface that are arranged back to back with each other. It can also be understood that the front side surface is located on the side of the air outlet mesh cover 1000 away from the fan blades of the air conditioner outdoor unit, and the rear side surface is located on the side of the air outlet mesh cover 1000 close to the fan blades of the air conditioner outdoor unit. It can also be understood that the front side surface is arranged toward the air outlet direction of the air outlet mesh cover 1000, and the rear side surface is arranged in the opposite direction of the air outlet direction, and the air flow flows from the rear side surface to the front side surface.

[0050] It is understandable that, referring to Figure 3As shown, in some embodiments, along the air outlet direction of the air outlet grille 1000, the first grille bar 102, the second grille bar 103 and the third grille bar 104 are provided with a first inclined surface 105 and a second inclined surface 106 arranged in sequence on one side thereof, which can be understood as follows: along the air outlet direction, the air outlet airflow first passes through the first inclined surface 105 and then passes through the second inclined surface 106. Along the air outlet direction of the air outlet grille 1000, the first grille bar 102, the second grille bar 103 and the third grille bar 104 are provided with a third inclined surface 107 and a fourth inclined surface 108 arranged in sequence on the other side thereof, which can be understood as follows: along the air outlet direction, the air outlet airflow first passes through the third inclined surface 107 and then passes through the fourth inclined surface 108. It should be noted that the inclination direction of the first inclined surface 105 is different from the inclination direction of the second inclined surface 106, and the inclination direction of the third inclined surface 107 is different from the inclination direction of the fourth inclined surface 108, so that the overall structure of the grille bar is similar to a rhombus.

[0051] In this embodiment, the thickness of the first grille bar 102, the second grille bar 103 and the third grille bar 104 gradually narrows or decreases from the approximately middle position to the front and rear ends along the air outlet direction, and the thickness direction of the grille bar is approximately perpendicular to the air outlet direction, so that the grille bar is thick in the middle and thin at both ends. Such a configuration can improve the wind gathering effect, and the air flow is gathered in the middle position of the air outlet mesh cover 1000 through the wind guiding effect of the first inclined surface 105, the second inclined surface 106, the third inclined surface 107 and the fourth inclined surface 108. It should be noted that in the air outlet area 110, each grille bar is arranged with the above-mentioned first inclined surface 105, the second inclined surface 106, the third inclined surface 107 and the fourth inclined surface 108, and the grille bars in the closed area 111 are not required, and the above-mentioned inclined surfaces may not be arranged.

[0052] Reference Figure 3 As shown, in some embodiments, the grille bars are of an axisymmetric structure, and the grille bars are symmetrical about the center line X, that is, the first inclined surface 105 and the third inclined surface 107 are symmetrical about the center line X, and the second inclined surface 106 and the fourth inclined surface 108 are symmetrical about the center line X, and the center line X can be understood as being set along the air outlet direction of the air outlet grille 1000. When the outlet air flow passes through the first inclined surface 105, the second inclined surface 106, the third inclined surface 107 and the fourth inclined surface 108, the outlet air flow gathers from both sides of the grille bars to the center line X of the grille bars, which plays a role in gathering wind.

[0053] It is understandable that, referring to Figure 3As shown, in some embodiments, the angle formed by the first inclined surface 105 and the wind outlet direction is smaller than the angle formed by the second inclined surface 106 and the wind outlet direction, and the angle formed by the third inclined surface 107 and the wind outlet direction is smaller than the angle formed by the fourth inclined surface 108 and the wind outlet direction, so that the grille bars are thick in the middle and thin at both ends, which can improve the wind gathering effect. Specifically, the angle formed by the first inclined surface 105 and the wind outlet direction can be understood as the angle β between the first inclined surface 105 and the center line X, and the angle formed by the second inclined surface 106 and the wind outlet direction can be understood as the angle α between the second inclined surface 106 and the center line X. In this embodiment, it can be understood that β is smaller than α.

[0054] It is understandable that, referring to Figure 3 As shown, in some embodiments, the angle β between the first inclined surface 105 and the air outlet direction is equal to the angle between the third inclined surface 107 and the air outlet direction, and β satisfies: 0.5°≤β<10°. In some embodiments, the angle α between the second inclined surface 106 and the air outlet direction is equal to the angle between the fourth inclined surface 108 and the air outlet direction, and α satisfies: 2°≤α≤10°. In this embodiment, by limiting the angle values ​​of α and β, β is made smaller than α, so that the thickness of the grille bar gradually narrows from the approximate middle position to the two ends along the air outlet direction, and the grille bar is thick in the middle and thin at the two ends. With the wind guiding function of the grille bar, the wind gathering effect is better, which can effectively reduce the wind resistance encountered by the air outlet heat dissipation, and is conducive to improving the heat dissipation effect.

[0055] It is understandable that, in some embodiments, the width direction of the first grille bar 102, the second grille bar 103 and the third grille bar 104 is roughly set along the air outlet direction of the air outlet grille 1000, the width of the first inclined surface 105 is greater than the width of the second inclined surface 106, and the width of the third inclined surface 107 is greater than the width of the fourth inclined surface 108. The thickness of the grille bar is gradually narrowed from the position close to the front end to the front and rear ends along the width direction, and the grille bar is thick in the middle and thin at both ends, which has a better wind gathering effect. It should be noted that in this embodiment, the width of each of the above-mentioned inclined surfaces is roughly set along the air outlet direction, and the width of each of the above-mentioned inclined surfaces refers to the actual measurement value, which can be directly measured using a measuring tool.

[0056] It should be noted that, in some embodiments, for the convenience of manufacturing, the air outlet mesh cover 1000 is an integrated structure. The air outlet mesh cover 1000 is made of plastic material, and the entire air outlet mesh cover 1000 is manufactured by an integrated injection molding process. Therefore, when designing the structure of the air outlet mesh cover 1000, it is necessary to consider how to facilitate the demolding of the air outlet mesh cover 1000 and facilitate mold processing and molding.

[0057] It is understandable that, referring to Figure 3As shown, in some embodiments, the ratio of the width of the first inclined surface 105 to the width of the second inclined surface 106 ranges from 5 / 3 to 8 / 3, for example, it can be 5 / 3, 2, 7 / 3, 8 / 3, etc. It can be understood that, along the air outlet direction, the width of the first inclined surface 105 is greater than the width of the second inclined surface 106. The ratio of the width of the third inclined surface 107 to the width of the fourth inclined surface 108 ranges from 5 / 3 to 8 / 3, for example, it can be 5 / 3, 2, 7 / 3, 8 / 3, etc. It can be understood that, along the air outlet direction, the width of the third inclined surface 107 is greater than the width of the fourth inclined surface 108, so that the thickness of the grille bar gradually narrows from the position close to the front end to the front and rear ends along the width direction. This embodiment combines the front and rear molds of the manufacturing mold to design the above-mentioned width ratio, which is not only convenient for mold production, but also the cross-section of the air outlet channel 109 between two adjacent grille bars on the air outlet side is smaller along the air outlet direction, which can further speed up the air outlet efficiency, and is conducive to reducing the air outlet wind resistance, and the heat dissipation effect is better. In this embodiment, the width direction of the above-mentioned inclined surface is substantially arranged along the air outlet direction.

[0058] It is understandable that in some embodiments, since the first grille bar 102, the second grille bar 103 and the third grille bar 104 have the same structure, the air outlet angles of the first grille bar 102, the second grille bar 103 and the third grille bar 104 are substantially equal, which can ensure normal air outlet and consistent air outlet direction. It should be noted that in this embodiment, the air outlet angles of the grille bars can be absolutely equal, but since there are generally certain manufacturing errors in the actual manufacturing process, the air outlet angles of the grille bars are not necessarily absolutely equal, and there may be certain deviations. Within a certain error range, the air outlet angles of the grille bars can be roughly equal.

[0059] It is understandable that, in some embodiments, the draft depths of the first grid bar 102, the second grid bar 103, and the third grid bar 104 are substantially equal, which can facilitate demolding, mold processing, and molding. It should be noted that, in this embodiment, the draft depths of the grid bars can be absolutely equal, but since there are generally certain manufacturing errors in the actual manufacturing process, the draft depths of the grid bars are not necessarily absolutely equal, and there may be certain deviations. Within a certain error range, the draft depths of the grid bars can be roughly equal.

[0060] It is understandable that, referring to Figure 7 and Figure 8As shown, in some embodiments, the air outlet grille 1000 includes a blocking portion 201 disposed in the closed area 111, the first grille bar 102, the second grille bar 103 and the third grille bar 104 are arranged obliquely, and the blocking portion 201 connects one end of the first grille bar 102, the second grille bar 103 and the third grille bar 104, and blocks the end of the air outlet channel 109 formed between the first grille bar 102, the second grille bar 103 and the third grille bar 104. In this embodiment, the blocking portion 201 can block the air outlet airflow from diffusing outward along the length direction of the grille bar, better gather the air outlet airflow in the middle position of the air outlet grille 1000, make the air outlet more concentrated and stable, increase the air outlet efficiency and stability of the wind wheel, and reduce aerodynamic noise.

[0061] Reference Figure 7 and Figure 8 As shown, in some embodiments, the blocking portion 201 is located on the front side of the air outlet mesh cover 1000, and the blocking portion 201 is connected to the front side surface of the plate body 200. The blocking portion 201 is a rib-like structure extending in a straight line direction. The length direction of the grille bars can be perpendicular to the length direction of the blocking portion 201. Due to the wind guiding effect of the grille bars, the outlet airflow will flow toward the blocking portion 201 after passing through the grille bars. The blocking portion 201 can block the outlet airflow from diffusing outward along the length direction of the grille bars, and better gather the outlet airflow in the middle position of the air outlet mesh cover 1000, so that the outlet airflow is more concentrated and stable, thereby increasing the outlet efficiency and stability of the wind wheel and reducing aerodynamic noise.

[0062] In some embodiments, the height of the blocking portion 201 is substantially flush with the height of the grille bars, which can facilitate the demolding of the air outlet grille 1000 and facilitate mold processing and molding, and also ensure that the blocking portion 201 can effectively block the diffusion of the air outlet airflow. It should be noted that in this embodiment, due to the fact that there are generally certain manufacturing process errors in the actual manufacturing process, the "substantially flush" is not necessarily absolutely flush, and there may be a certain deviation. Within a certain error range, the two can be roughly flush.

[0063] It should be noted that when assembling the air outlet grille 1000, it is easy to have the air outlet grille 1000 installed upside down or misplaced. Figure 1 and Figure 7As shown, in some embodiments, the air outlet grille 1000 is provided with an identification member 300, and the identification member 300 is installed in the closed area 111, wherein the closed area 111 has four corners, and the identification member 300 is located at the position of one of the corners of the closed area 111. In this embodiment, the identification member 300 can be used to identify the installation direction of the air outlet grille 1000 to avoid reverse installation of the air outlet grille 1000, and the identification member 300 can be in a triangular, circular or square shape. It should be noted that the identification member 300 is located at a position corresponding to the end of the grille bar, and the identification member 300 can also block the air outlet airflow from diffusing outward along the length direction of the grille bar, so as to better gather the air outlet airflow in the middle of the air outlet grille 1000.

[0064] Reference Figure 8 As shown, in some embodiments, the number of the blocking parts 201 is at least two, and the plurality of blocking parts 201 are parallel to each other, wherein a spacing space is formed between the two blocking parts 201, and the spacing space is conducive to blocking the airflow from diffusing to both sides, thereby improving the wind gathering effect. Specifically, the two blocking parts 201 are connected by connecting ribs, and the connecting ribs can be perpendicular to the blocking parts 201, and the connecting ribs can enhance the structural strength of the blocking parts 201.

[0065] It should be noted that the airflow has multiple flow directions. Most of the airflow flows mainly along the airflow direction of the air outlet grille 1000. A portion of the airflow flows along the length direction of the grille bar after being guided by the grille bar, thereby diffusing to both sides of the length direction of the grille bar. Figure 7 and Figure 8 As shown, in some embodiments, the position of the blocking portion 201 corresponds to the position of the identification member 300. In a certain flow direction of the outlet airflow, the blocking portion 201 and the identification member 300 are arranged in sequence along the flow direction. The flow direction can be understood as the length direction of the grille bar, which is the secondary flow direction of the outlet airflow, so that a part of the outlet airflow flowing out of the grille bar can also pass through the identification member 300 after passing through the blocking portion 201. It can be understood that a double structure is achieved to block the outlet airflow from diffusing outward along the length direction of the grille bar, so as to better gather the outlet airflow in the middle position of the outlet mesh cover 1000. The identification member 300 can abut against the blocking portion 201 to achieve a positioning effect. Specifically, the identification member 300 is a triangular structure, and the length direction of the blocking portion 201 is inclined relative to the horizontal direction, so that the blocking portion 201 can abut against the hypotenuse of the identification member 300 to achieve a positioning effect.

[0066] Reference Figure 1 and Figure 7As shown, in some embodiments, the grille bars are tilted, and the angle between the length direction of the grille bars and the horizontal direction is θ. When the above-mentioned identification member 300 is arranged, θ satisfies: 0°<θ<90°, and θ can be 60°, 45° or 30°, etc., so that the grille bars can guide the outlet airflow to the identification member 300, which can reduce noise. It should be noted that if θ is 0°, the outlet airflow is easy to diffuse to both sides horizontally without passing through the identification member 300, thereby generating noise. If θ is 90°, the outlet airflow is easy to diffuse to both sides up and down without passing through the identification member 300, thereby generating noise. When the air outlet grille 1000 is square, θ is 45°, which has a better effect, so that the grille bars can directly guide the outlet airflow to the identification member 300.

[0067] It is understandable that, referring to Fig.12 As shown, in some embodiments, the air outlet mesh cover 1000 is provided with two air outlet areas 110, the air outlet mesh cover 1000 is a rectangular structure, and the air outlet mesh cover 1000 can be understood as including an upper mesh cover and a lower mesh cover, the upper mesh cover and the lower mesh cover are an integrated structure, which can be easily manufactured, and the air outlet mesh cover 1000 is made of plastic material, and the entire air outlet mesh cover 1000 is manufactured by an integrated injection molding process. In this embodiment, the installation and disassembly efficiency of the air outlet mesh cover 1000 is improved, and the structure of the air outlet mesh cover 1000 is more reliable, firm and not easy to deform.

[0068] Reference Figures 9 to 11 As shown, the air outlet mesh cover 1000 includes a first reinforcing rib 202 and a second reinforcing rib 203, and the first reinforcing rib 202 and the second reinforcing rib 203 are both located in the closed area 111, and the first reinforcing rib 202 intersects with the second reinforcing rib 203, which can enhance the structural strength of the closed area 111, and the cross-sectional area of ​​the first reinforcing rib 202 is greater than the cross-sectional area of ​​the second reinforcing rib 203, the first reinforcing rib 202 can be understood as a thick reinforcing rib, and the second reinforcing rib 203 can be understood as a thin reinforcing rib, the first reinforcing rib 202 is thicker than the second reinforcing rib 203, which can further enhance the structural strength of the closed area 111, and can enhance the structural strength of the air outlet mesh cover 1000 as a whole, so that the air outlet mesh cover 1000 is not easy to deform, the air outlet mesh cover 1000 is not easy to loosen, and the noise generated by the air outlet mesh cover 1000 can be reduced. The number of the first reinforcing ribs 202 and the number of the second reinforcing ribs 203 are both multiple, and the multiple first reinforcing ribs 202 and the multiple second reinforcing ribs 203 can be arranged in a criss-cross pattern to further enhance the structural strength.

[0069] It should be noted that if the first reinforcing rib 202 and the second reinforcing rib 203 are designed to be uniform reinforcing ribs, that is, the cross-sectional area of ​​the first reinforcing rib 202 is the same as the cross-sectional area of ​​the second reinforcing rib 203, then an excessively thick glue position will be easily generated at the intersection thereof, which will cause shrinkage marks to be generated when the front of the air outlet grille 1000 is demolded, affecting the appearance. In this embodiment, making the cross-sectional area of ​​the first reinforcing rib 202 larger than the cross-sectional area of ​​the second reinforcing rib 203 can be understood as that the width of the first reinforcing rib 202 is larger than the width of the second reinforcing rib 203, or that the thickness of the first reinforcing rib 202 is larger than the thickness of the second reinforcing rib 203, which can facilitate the demolding of the air outlet grille 1000 and avoid shrinkage marks to be generated when the air outlet grille 1000 is demolded, affecting the appearance.

[0070] It is understandable that, referring to Figure 4 As shown, in some embodiments, the cross-sectional area of ​​the first reinforcing rib 202 is substantially equal to the cross-sectional area of ​​the grille bar in the air outlet area 110, which is convenient for mold processing and molding. It should be noted that in this embodiment, since there is generally a certain manufacturing error in the actual manufacturing process, the cross-sectional area of ​​the first reinforcing rib 202 is not necessarily absolutely equal to the cross-sectional area of ​​the grille bar, and there may be a certain deviation. Within a certain error range, the cross-sectional areas of the two can be roughly equal.

[0071] It is understandable that, referring to Figure 4 As shown, in some embodiments, along the air outlet direction of the air outlet mesh cover 1000, the height of the first reinforcing rib 202 is substantially equal to the height of the grille bars in the air outlet area 110, which can facilitate demolding, mold processing and molding. It should be noted that in this embodiment, due to the fact that there are generally certain manufacturing errors in the actual manufacturing process, the height of the first reinforcing rib 202 and the height of the grille bars are not necessarily absolutely equal, and there may be a certain deviation. Within a certain error range, the heights of the two can be roughly equal. Figure 4 The height direction in the figure can be understood as the height direction of the first reinforcing rib 202 and the height direction of the grille bar. Figure 4 As shown, in some embodiments, the first reinforcing rib 202 is located between two adjacent grille bars.

[0072] It is understandable that, referring to Fig.10As shown, in some embodiments, along the air outlet direction of the air outlet grille 1000, the height of the second reinforcing rib 203 is less than the height of the first reinforcing rib 202. It should be noted that, at the rear side of the plate body 200, due to the manufacturing process, the position of the grille bars on the rear side will leave a stepped surface 112, and the second reinforcing rib 203 spans more stepped surfaces 112. If the height of the second reinforcing rib 203 is too high, it will affect the deformation. The height should not be too high, and the height of the second reinforcing rib 203 should be as small as possible. In addition, the second reinforcing rib 203 and the first reinforcing rib 202 can specifically correspond to two grooves in the manufacturing mold. The difference between the height of the second reinforcing rib 203 and the height of the first reinforcing rib 202 can be understood as the different depths of the two grooves. The two grooves can serve as the internal flow channel of the manufacturing mold, improve the flow of plastic during the molding process of the plastic part, and help fill the mold cavity of the manufacturing mold.

[0073] It is understandable that, referring to Fig.10 and Fig.11 As shown, in some embodiments, the air outlet mesh cover 1000 further includes a third reinforcing rib 204, which is located on the inner side of the frame 100. It can also be understood that the third reinforcing rib 204 is located in the closed area 111. The third reinforcing rib 204 is arranged around the air outlet area 110. It can be understood that the extension direction of the third reinforcing rib 204 is the same as the extension direction of the frame 100. The first reinforcing rib 202 can be connected to the third reinforcing rib 204, thereby enhancing the structural strength of the air outlet mesh cover 1000. The second reinforcing rib 203 can also be connected to the third reinforcing rib 204, thereby enhancing the structural strength of the air outlet mesh cover 1000.

[0074] It is understandable that, referring to Fig.10 and Fig.11 As shown, in some embodiments, the third reinforcing rib 204 and the frame 100 form a double-layer frame 100 structure. The double-layer frame 100 can increase the deformation resistance of the air outlet mesh cover 1000. In addition, it can also ensure effective fitting with the panel of the air-conditioning outdoor unit, and at the same time form a double-layer waterproof layer to prevent water from entering the interior of the air outlet mesh cover 1000, reduce ice on the inside, and thereby protect the fan blades of the air-conditioning outdoor unit.

[0075] It is understandable that, referring to Fig. 9 and Fig.10As shown, in some embodiments, the air outlet mesh cover 1000 includes an annular rib 206, and the annular rib 206 is located at the junction of the closed area 111 and the air outlet area 110. It can also be understood that the annular rib 206 divides the closed area 111 and the air outlet area 110, and the annular rib 206 is connected to the rear side of the plate body 200. The annular rib 206 can be a circular ring structure, and the end of the grille bar located in the air outlet area 110 is connected to the inner circumference of the annular rib 206, which can enhance the structural strength. The end of the first reinforcing rib 202 can be connected to the annular rib 206. The end of the second reinforcing rib 203 can also be connected to the annular rib 206, which can further enhance the structural strength. Specifically, the end of the first reinforcing rib 202 or the end of the second reinforcing rib 203 is connected to the outer circumference of the annular rib 206.
