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.

[0045] The following content should be integrated into the writing process as needed to explain the relevant content:

[0046] In the description of the present invention, it is necessary to understand that the terms "center", "thickness", "up", "down", "front", "back", "left", "right", "horizontal", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0047] In the description of the present invention, "plurality" means two or more.

[0048] Reference below Figure 1-Figure 11 The air outlet cover assembly 100 according to an embodiment of the present invention is described.

[0049] Combination Figures 1 to 5 as well as Fig.11 According to an embodiment of the present invention, the air outlet cover assembly 100 includes: a mounting plate 110 and an air outlet cover 120, the mounting plate 110 has a vent 111, the air outlet cover 120 is installed on the mounting plate 110, the air outlet cover 120 includes: an air outlet grille 121 and a frame 122, the frame 122 is connected to the air outlet grille 121, and the frame 122 is provided with a plurality of connection structures 123, the connection structure 123 is used to be connected to the mounting plate 110, and at least two of the plurality of connection structures 123 are different to form an error-proofing structure.

[0050] Specifically, a mounting plate 110 is formed on the air conditioner casing, and the mounting plate 110 has a vent 111. An electronic control component is disposed in the air conditioner casing, and the electronic control component can dissipate heat to the outside through the vent 111. An air outlet hood 120 is installed at the position of the vent 111 on the mounting plate 110. The air outlet hood 120 can prevent foreign matter from entering the air conditioner casing from the air outlet, thereby preventing foreign matter from affecting the operation of the electronic control component.

[0051] Furthermore, the frame 122 is connected to the mounting plate 110 through multiple sets of connecting structures 123 to realize the assembly of the frame 122 and the mounting plate 110, and the frame 122 is connected to the air outlet hood 120, so that the assembly of the air outlet hood 120 and the mounting plate 110 can be realized, and the air outlet grille 121 and the vent 111 are arranged relative to each other to facilitate air outlet.

[0052] Furthermore, at least two groups of connection structures 123 among the multiple groups of connection structures 123 are different. For example, two groups of connection structures 123 among the multiple groups of connection structures 123 may have different sizes, so that during installation, the installation direction of the air outlet hood 120 can be determined by the size of the connection structure 123 to prevent the air outlet hood 120 from being installed upside down, thereby improving the installation efficiency of the air outlet hood 120; in addition, the two groups of connection structures 123 can also be constructed with different shapes and spacings, or the two groups of connection structures 123 can be asymmetrically arranged with respect to the geometric center of the frame 122, etc., so as to achieve mechanical error prevention of the air outlet hood 120 and improve the installation efficiency of the air outlet hood 120.

[0053] Of course, it is understandable that there may be two, three, etc. groups in the multiple groups of connection structures 123, and the specific number is not limited here, as long as it can prevent errors in the installation of the air outlet cover 120.

[0054] In the related art, an arrow is usually set on the mesh cover to indicate the installation direction. However, the arrow mark is small and it is not easy to distinguish the installation direction, which makes it easy to install the mesh cover incorrectly during installation, affecting the assembly efficiency of the mesh cover.

[0055] The present application sets multiple groups of connecting structures 123 on the air outlet hood 120, and at least two of the multiple groups of connecting structures 123 are different, so that when the air outlet hood 120 is assembled, the installation direction of the air outlet hood 120 can be determined by the connecting structures 123, thereby preventing the air outlet hood 120 from being installed reversely, thereby improving the assembly convenience and efficiency of the air outlet hood 120.

[0056] According to the air outlet hood assembly 100 of the present invention, a plurality of connection structures 123 are provided on the air outlet hood 120, so that the air outlet hood 120 can be installed on the mounting plate 110 through the connection structures 123. By making at least two of the plurality of connection structures 123 different, when installing the air outlet hood 120, the installation direction of the air outlet hood 120 can be determined through the connection structures 123, thereby preventing the air outlet hood 120 from being installed in reverse, and effectively improving the assembly convenience and efficiency of the air outlet hood 120.

[0057] Combination Figures 1 to 5 as well as Fig.11 In some embodiments of the present invention, the frame 122 is constructed as a square frame, which includes four connecting plates 1221 connected end to end in sequence; the connecting structure 123 includes a first connecting structure 1231 and a second connecting structure 1232, which are respectively arranged on two connecting plates 1221 arranged oppositely or adjacently in the square frame, and the first connecting structure 1231 is different from the second connecting structure 1232.

[0058] Specifically, the four connecting plates 1221 are connected end to end in sequence in the circumferential direction of the air outlet grille 121 to construct the frame 122 into a square frame, and the frame 122 is arranged around the air outlet grille 121 in the circumferential direction and connected to the air outlet grille 121, wherein two connecting plates 1221 among the four connecting plates 1221 are respectively provided with a first connecting structure 1231 and a second connecting structure 1232, and the connecting plate 1221 provided with the first connecting structure 1231 and the connecting plate 1221 provided with the second connecting structure 1232 can be arranged opposite to each other, and the first connecting structure 1231 and the second connecting structure 1232 are different (for example: the first connecting structure 1231 can be constructed as a snap-on structure, and the second connecting structure 1232 can be constructed as a threaded connecting structure 123; or the size of the first connecting structure 1231 can be larger than the size of the second connecting structure 1232, etc.), so as to facilitate the determination of the installation direction of the air outlet hood 120 by the first connecting structure 1231 and the second connecting structure 1232, thereby improving the installation convenience of the air outlet hood 120.

[0059] Optionally, a connecting plate 1221 provided with a first connecting structure 1231 and a connecting plate 1221 provided with a second connecting structure 1232 can be arranged adjacent to each other, and the first connecting structure 1231 and the second connecting structure 1232 are different, so that the installation direction of the air outlet hood 120 can be determined by the first connecting structure 1231 and the second connecting structure 1232, thereby improving the installation convenience of the air outlet hood 120.

[0060] Reference Fig.11 In some embodiments of the present invention, the connection structure 123 also includes a third connection structure 1233. The third connection structure 1233 can be arranged on two connection plates 1221 among the four connection plates 1221 on which the first connection structure 1231 and the second connection structure 1232 are not arranged, so that the four connection plates 1221 can all be connected to the mounting plate 110, thereby improving the assembly reliability of the air outlet cover 120 and the mounting plate 110.

[0061] Furthermore, the third connecting structure 1233 can be the same as the first connecting structure 1231, so as to improve the processing convenience of the air outlet hood 120 and improve the production and processing efficiency of the air outlet hood 120. At the same time, the second connecting structure 1232 is different from the third connecting structure 1233 and the first connecting structure 1231, so as to facilitate the determination of the installation direction of the air outlet hood 120 through the second connecting structure 1232. The third connecting structure 1233 can be the same as the second connecting structure 1232. This structure has the same technical effect as the above-mentioned structure and will not be elaborated here.

[0062] like Fig.11As shown, in some embodiments of the present invention, the first connection structure 1231 includes a plurality of first connection parts 12311, the first connection parts 12311 are used to be connected to the mounting plate 110, and the plurality of first connection parts 12311 are spaced apart on the connecting plate 1221; the second connection structure 1232 includes a plurality of second connection parts 12321, the second connection parts 12321 are used to be connected to the mounting plate 110, and the plurality of second connection parts 12321 are spaced apart on the connecting plate 1221; wherein the spacing between two adjacent first connection parts 12311 is smaller than the spacing between two adjacent second connection parts 12321.

[0063] Specifically, multiple first connection parts 12311 are arranged at intervals on the connecting plate 1221, and the multiple first connection parts 12311 are all connected to the mounting plate 110, which is conducive to ensuring the connection reliability between the frame 122 and the mounting plate 110, thereby helping to improve the assembly reliability of the air outlet hood 120 and the mounting plate 110. Similarly, multiple second connection parts 12321 are arranged at intervals on the connecting plate 1221, and the multiple second connection parts 12321 are all connected to the mounting plate 110. The first connection parts 12311 and the second connection parts 12321 are adjacent to or opposite to each other, which is conducive to further ensuring the connection reliability between the frame 122 and the mounting plate 110, thereby helping to further improve the assembly reliability between the air outlet hood 120 and the mounting plate 110.

[0064] Furthermore, the spacing between two adjacent first connecting parts 12311 is smaller than the spacing between two adjacent second connecting parts 12321. When the air outlet hood 120 is installed upside down, the first connecting structure 1231 and the second connecting structure 1232 cannot be connected to the mounting plate 110, thereby forming an error-proof structure, which facilitates determining the installation direction of the air outlet hood 120.

[0065] The first connection portion 12311 and the second connection portion 12321 may both be configured as a snap-fit ​​structure, and the air outlet cover 120 may be fixedly connected to the mounting plate 110 by snap-fitting.

[0066] like Figure 6 As shown, in some embodiments of the present invention, the frame 122 further includes a fixing plate 124 , which is connected between the air outlet grille 121 and the connecting plate 1221 and is formed with a mounting hole 1241 .

[0067] Specifically, combined Figure 1 and Figure 6The air outlet grille 121 is connected to the connecting plate 1221 through a fixing plate 124. The air outlet grille 121 can be assembled to the mounting plate 110 through a connecting structure 123 on the connecting plate 1221. A mounting hole 1241 is formed on the fixing plate 124. The fixing plate 124 can be connected to the mounting plate 110 through threaded connectors (such as screws or bolts, etc.), thereby further improving the installation reliability of the air outlet cover 120 and the mounting plate 110.

[0068] Reference Figure 6 In some embodiments of the present invention, the diameter of the mounting hole 1241 is d, and satisfies the relationship: d≥18 mm.

[0069] Specifically, the mounting hole 1241 can be constructed as a countersunk screw hole, which is located in the middle of the countersunk screw hole and is coaxially arranged with the countersunk screw hole. The screw can be automatically driven by a robot to improve the installation efficiency of the air outlet hood 120. The screw can pass through the screw hole to the fixing plate 124 and connect the fixing plate 124 with the mounting plate 110. The mounting hole 1241 can increase the contact area between the screw and the fixing plate 124, effectively improving the fixing effect of the screw, and the diameter d ≥ 18 mm of the mounting hole 1241 is convenient for the positioning and installation of the screw, thereby improving the assembly convenience of the air outlet hood 120.

[0070] Combination Figures 7 to 10 In some embodiments of the present invention, the air outlet grille 121 is bulged outward relative to the frame 122, and the bulging height of the air outlet grille 121 relative to the frame 122 gradually increases from the circumference of the air outlet grille 121 to the center position.

[0071] Specifically, the air outlet grille 121 bulges from the position where it is connected to the frame 122 along the air outlet direction toward the direction away from the frame 122, and along the outer peripheral side of the air outlet grille 121 extending toward the geometric center of the air outlet grille 121, the bulging height of the air outlet grille 121 relative to the frame 122 gradually increases, and the highest point of the bulge of the air outlet grille 121 relative to the frame 122 is the air outlet center of the air outlet cover 120. When the air outlet cover 120 is deformed due to long-term use, the outward bulge of the air outlet grille 121 relative to the air outlet frame 122 can effectively prevent the air outlet grille 121 from deforming to the point where its geometric center is lower than the connection between the air outlet frame and the air outlet grille 121, thereby ensuring the air outlet flow field of the air outlet cover 120 and effectively preventing the air outlet noise from increasing due to the deformation of the air outlet cover 120.

[0072] It should be noted that “outside” refers to the direction extending along the ventilation opening 111 toward the outside.

[0073] Combination Figures 7 to 10 In some embodiments of the present invention, the raised outer surface contour of the air outlet grille 121 is a portion of a spherical surface.

[0074] Specifically, the raised outer surface contour of the air outlet grille 121 is constructed as an arc surface, which facilitates the processing of the air outlet grille 121, and can ensure the smoothness of the appearance of the air conditioner shell and improve the aesthetics of the air conditioner shell. At the same time, the arc-shaped structure of the air outlet grille 121 can effectively improve the ventilation effect.

[0075] like Figure 7 As shown, in some embodiments of the present invention, the protrusion height of the air outlet grille 121 relative to the frame 122 is H, and satisfies the relationship: H≥4mm.

[0076] Specifically, H≥4mm can effectively offset the deformation of the air outlet hood 120 after long-term use, and prevent the geometric center of the air outlet grille 121 (i.e., the air outlet center of the air outlet grille 121) from being recessed in the axial direction to a position lower than the position where the frame 122 and the air outlet grille 121 are connected after the air outlet hood 120 is deformed. This reduces the influence of the deformation of the air outlet hood 120 on the air outlet volume and air outlet noise, ensures the air outlet volume of the air outlet hood 120 after deformation, and can effectively reduce the air outlet noise of the air outlet hood 120 after deformation.

[0077] like Fig.10 As shown, in some embodiments of the present invention, the frame 122 is provided with a connecting edge 1222 extending in a curve L1, the connecting edge 1222 is connected to the air outlet grille 121, and the frame 122 is provided with a plurality of weight reducing holes 1223, and the distribution curve of the plurality of weight reducing holes 1223 is L2, and the curve L1 is parallel to the curve L2.

[0078] Specifically, combined Figures 7 to 10 A plurality of weight-reducing holes 1223 are provided on the frame 122, and the weight-reducing holes 1223 are provided through the connecting plate 1221 in the thickness direction of the connecting plate 1221, wherein at least three connecting plates 1221 out of the four connecting plates 1221 are provided with a plurality of weight-reducing holes 1223, and the plurality of weight-reducing holes 1223 are evenly spaced and arranged on the connecting plate 1221, and the weight-reducing holes 1223 are provided on the frame 122 to reduce the weight of the air outlet hood 120, and the materials required for producing the air outlet hood 120 can be effectively reduced, which is beneficial to reducing the production cost of the air outlet hood 120.

[0079] It should be noted that the “thickness direction of the connecting plate 1221 ” can be understood as a direction extending straightly from the connecting plate 1221 to the geometric center of the frame 122 .

[0080] Among them, weight-reducing holes 1223 can be opened in the connecting plates 1221 located on the left, right and bottom sides among the three connecting plates 1221. Of course, it can be understood that weight-reducing holes 1223 can be set on all four connecting plates 1221. The specific arrangement of the weight-reducing holes 1223 can be determined according to actual production needs and is not specifically limited here.

[0081] Further references Fig.10 One side of the connecting plate 1221 connected to the air outlet grille 121 in the axial direction is constructed as a connecting side 1222, and the connecting side 1222 extends in a curve L1, and L1 is arranged in parallel with the raised outer surface contour of the air outlet grille 121. The multiple weight reduction holes 1223 on the connecting plate 1221 form a distribution curve L2 of the multiple weight reduction holes 1223 close to the connecting side 1222, and L1 is arranged in parallel with L2, which is conducive to ensuring that the structural strength of the positions where the weight reduction holes 1223 are set on the connecting plate 1221 is the same, preventing the structural strength of the connecting plate 1221 from being inconsistent due to the uneven distribution of the weight reduction holes 1223, and reducing the risk of the connecting plate 1221 being crushed.

[0082] like Figure 7 As shown, in some embodiments of the present invention, the dimension of the weight-reducing hole 1223 in the thickness direction of the frame 122 is D, and satisfies the relationship: D≤8mm.

[0083] It should be noted that the “thickness direction of the frame 122 ” may be understood as the direction in which the air outlet grille 121 bulges.

[0084] Specifically, the dimension D of the weight-reducing hole 1223 in the thickness direction of the frame 122 is ≤8 mm, so as to ensure that the strength of the connecting plate 1221 can meet the safety specifications and avoid damage to the frame 122 due to insufficient structural strength of the connecting plate 1221. While achieving weight reduction and cost reduction, the structural strength of the frame 122 can be guaranteed, thereby ensuring the service life of the air outlet hood 120 and reducing the risk of the air outlet hood 120 being crushed during assembly.

[0085] Combination Figure 6 and Fig.11 In some embodiments of the present invention, the air outlet grille 121 includes: a plurality of first grille portions 1211, the first grille portion 1211 is annular, and the plurality of first grille portions 1211 are concentrically arranged, and each first grille portion 1211 has a plurality of first air outlets 1212 arranged in a circular pattern; a second grille portion 1213, the second grille portion 1213 is arranged radially outward of the outermost annular grille, and is located between the frame 122 and the outermost annular grille, the second grille portion 1213 has a plurality of second air outlets 1214 arranged in an arc, and the center of the arc coincides with the center of the first grille portion 1211.

[0086] Specifically, the first grille portion 1211 is constructed in a circular ring shape, and a plurality of first grille portions 1211 are provided. In a direction extending from the geometric center of the air outlet grille 121 along the radial direction toward the frame 122, the annular inner diameters of the plurality of first grille portions 1211 gradually increase, wherein the first grille portion 1211 with the smallest annular inner diameter among the plurality of first grille portions 1211 has the largest distance from the geometric center of the frame 122 in the thickness direction of the air outlet cover 120, and the first grille portion 1211 with the largest annular inner diameter among the plurality of first grille portions 1211 has the smallest vertical distance from the connecting edge 122 of the frame 122 in the thickness direction of the air outlet cover 120, so as to construct the raised outer surface contour of the air outlet grille 121 into an arc shape.

[0087] It should be noted that the “vertical distance” is also the distance between the air outlet grille 121 and the connecting edge 122 in the axial direction.

[0088] The first grille portion 1211 is provided with a first air outlet 1212 , which extends in an arc shape to increase the size of the first air outlet 1212 , and a plurality of first air outlets 1212 are provided, and the plurality of first air outlets 1212 are arranged in a circle, and the vent 111 can discharge air to the outside through the first air outlet 1212 .
