[0055] The connecting portion 122 cooperates with and is connected to the first mounting portion 112 after the guiding cooperation of the guiding portion 123 and the second mounting portion 113. The guiding cooperation of the guiding portion 123 and the second mounting portion 113 can effectively improve the cooperation accuracy between the connecting portion 122 and the first mounting portion 112, and prevent the air outlet cover 120 from being unable to be installed on the mounting plate 110 due to the misalignment of the connecting portion 122 and the first mounting portion 112, which is beneficial to improving the assembly convenience of the air outlet cover 120.

[0056] In the related art, no guide structure is provided on the air outlet hood. When the air outlet hood is installed, the buckle positions on the air outlet hood are easily deviated from the buckle holes on the mounting plate, resulting in poor assembly convenience of the air outlet hood.

[0057] The present application provides a guide portion 123 on the air outlet hood 120, and makes the cooperation between the guide portion 123 and the second mounting portion 113 precede the cooperation between the connecting portion 122 and the first mounting portion 112. The air outlet hood 120 can be positioned and installed with the mounting plate 110 through the guide portion 123 and the second mounting portion 113, and the guide portion 123 can guide the installation of the air outlet hood 120, thereby effectively improving the cooperation accuracy between the air outlet hood 120 and the mounting plate 110, preventing the air outlet hood 120 from being unable to be installed on the mounting plate 110 due to the misalignment of the connecting portion 122 and the first mounting portion 112, thereby effectively improving the assembly convenience of the air outlet hood 120.

[0058] According to the air outlet hood assembly 100 of the present invention, a guide portion 123 is provided on the air outlet hood 120, and the cooperation between the guide portion 123 and the second mounting portion 113 precedes the cooperation between the connecting portion 122 and the first mounting portion 112, so as to play a role in positioning and installing the air outlet hood 120 and the mounting plate 110. At the same time, the guide portion 123 can guide the installation of the air outlet hood 120, effectively improve the cooperation accuracy between the connecting portion 122 and the first mounting portion 112, ensure that the connecting portion 122 can be connected to the first mounting portion 112, and effectively improve the assembly convenience of the air outlet hood 120.

[0059] Combination Figure 3 , Figure 5 , Fig.11 , Fig.12 and Fig.13 In some embodiments of the present invention, the connecting portion 122 includes: a connecting plate 1221 and a hook 1222, one end of the connecting plate 1221 is connected to the frame 121 and extends to one side of the mounting plate 110, the connecting plate 1221 is penetrated through the mounting plate 110, the hook 1222 is arranged on one side of the connecting plate 1221 in the thickness direction and is located at the other end of the connecting plate 1221, and the hook 1222 is connected to the first mounting portion 112 by being snap-connected.

[0060] It should be noted that the “thickness direction of the connecting plate 1221 ” can be understood as the direction extending perpendicularly from the geometric center of the frame 121 to the frame 121 . The thickness direction of the connecting plate 1221 is the same as the thickness direction of the connecting portion 122 .

[0061] Specifically, a connecting plate 1221 is provided on the surface of the side opposite to the mounting plate 110 of the frame 121, and the connecting plate 1221 extends from the frame 121 to one side of the mounting plate 110 and is penetrated through the mounting plate 110, and the hook 1222 is provided at the end of the connecting plate 1221 away from the frame 121, and the hook 1222 is provided on a side wall surface where the connecting plate 1221 and the frame 121 are adjacent, and the hook 1222 and the connecting plate 1221 are arranged at an angle, and the first mounting portion 112 can be constructed as a snap ring or a flange and the like, and the hook 1222 can be snap-connected to the first mounting portion 112, thereby realizing the connection between the air outlet hood 120 and the mounting plate 110, and the snap-fitting method can effectively improve the assembly convenience of the air outlet hood 120 and the mounting plate 110, and improve the assembly efficiency of the air outlet hood assembly 100.

[0062] Combination Figure 3 and Figure 5 In some embodiments of the present invention, the first mounting portion 112 includes: a first mounting hole 1121, the first mounting hole 1121 is used for the connecting portion 122 to pass through; a snap-fit ​​flange 1122, the snap-fit ​​flange 1122 is provided on a side surface of the mounting plate 110 away from the air outlet cover 120, and extends from the edge of the first mounting hole 1121 to a side away from the air outlet cover 120, and the hook 1222 is snap-fitted with the snap-fit ​​flange 1122.

[0063] Specifically, the first mounting hole 1121 is arranged on a side of the mounting plate 110 opposite to the air outlet cover 120 in the first direction. A snap-in flange 1122 is also arranged on the mounting plate 110. The snap-in flange 1122 is arranged on a side surface of the mounting plate 110 which is away from the air outlet cover 120 in the first direction and is connected to a side edge of the first mounting hole 1121. The snap-in flange 1122 extends along the first direction in a direction away from the air outlet cover 120.

[0064] It should be noted that the “first direction” can be understood as the thickness direction of the air outlet cover assembly 100, and the “second direction” can be understood as the height direction of the air outlet cover assembly 100, or can be understood as the up and down direction of the air outlet cover assembly 100. For specific directions, please refer to Figure 1 and Figure 2 shown.

[0065] Furthermore, the connecting plate 1221 can pass through the first mounting hole 1121, the hook 1222 and the snap-fit ​​flange 1122 are arranged opposite to each other, and the hook 1222 can be snap-fitted with the snap-fit ​​flange 1122, thereby realizing the connection between the air outlet hood 120 and the mounting plate 110, and can effectively improve the assembly efficiency of the air outlet hood 120 and the mounting plate 110.

[0066] Combination Figure 2 , Figures 11 to 13 In some embodiments of the present invention, the guide portion 123 includes: a support plate 1231 and a guide rib 1232, one end of the support plate 1231 is connected to the frame 121 and extends toward one side of the mounting plate 110, the guide rib 1232 is provided on the support plate 1231, and the guide rib 1232 extends from the other end of the support plate 1231 toward one side of the frame 121, and in the extension direction, the protruding height of the guide rib 1232 relative to the support plate 1231 increases gradually.

[0067] Specifically, the support plate 1231 is connected to a side surface of the frame 121 opposite to the mounting plate 110 in the first direction, and the support plate 1231 extends toward the mounting plate 110 along the first direction. A guide rib 1232 is provided on one side surface of the support plate 1231 in its thickness direction. The guide rib 1232 extends from one end of the support plate 1231 away from the frame 121 to the side of the frame 121. In the direction extending from the mounting plate 110 toward the air outlet cover 120 in the first direction, the protruding height of the guide rib 1232 relative to the support plate 1231 gradually increases.

[0068] It should be noted that the “thickness direction of the support plate 1231 ” is the same as the “thickness direction of the connection plate 1231 ”.

[0069] Furthermore, when the air outlet hood 120 is installed on the mounting plate 110, the support plate 1231 first cooperates with the second mounting portion 113 to realize the positioning of the air outlet hood 120 and the mounting plate 110, and the second mounting portion 113 can press against the guide rib 1232. The guiding of the installation direction of the air outlet hood 120 is realized through the cooperation of the guide rib 1232 and the second mounting portion 113. There is no need to manually adjust the installation direction of the air outlet hood 120, so that the air outlet hood 120 is easy to install, and then the connecting portion 122 extends into the first mounting portion 112, and the hook 1222 is engaged with the snap-fit ​​flange 1122 to realize the assembly of the air outlet hood 120 and the mounting plate 110, while ensuring the assembly reliability of the air outlet hood 120 and the mounting plate 110.

[0070] Combination Figure 2 , Figure 4 and Figure 5 In some embodiments of the present invention, the second mounting portion 113 includes: a second mounting hole 1131 and a guide flange 1132, the second mounting hole 1131 is used for the guide portion 123 to pass through, the guide flange 1132 is arranged on the side surface of the mounting plate 110 away from the air outlet cover 120, and extends from the edge of the second mounting hole 1131 to the side away from the air outlet cover 120, and the guide rib 1232 is guided and matched with the guide flange 1132.

[0071] Specifically, the second mounting hole 1131 is arranged on a side surface of the mounting plate 110 opposite to the air outlet cover 120 in the first direction, and a guide flange 1132 is also arranged on the mounting plate 110. The guide flange 1132 is arranged on a side surface of the mounting plate 110 away from the air outlet cover 120, and the guide flange 1132 is connected to a side edge of the second mounting hole 1131. The guide flange 1132 extends along the first direction away from the air outlet cover 120, and the guide flange 1132 can be arranged opposite to the guide rib 1232 so that the guide flange 1132 can be pressed against the guide rib 1232.

[0072] Furthermore, when the air outlet cover 120 is installed to the mounting plate 110, the support plate 1231 can pass through the second mounting hole 1131, and the guide flange 1132 can press against the guide rib 1232. In the direction in which the mounting plate 110 extends toward the air outlet cover 120, the protrusion height of the guide rib 1232 relative to the support plate 1231 gradually increases. The guide flange 1132 can drive the guide portion 123 to move in a direction away from the geometric center of the frame 121 through the guide rib 1232. The guide portion 123 is connected to the frame 121, and the frame 121 is connected to the connecting portion 122. The guide portion 123 can drive the connecting portion 122 to move in a direction away from the geometric center of the frame 121 through the frame 121, thereby preventing the connecting portion 122 from being unable to connect and cooperate with the first mounting portion 112 due to deformation of the frame 121.

[0073] In the related art, the air outlet hood is made of PP material (polypropylene material), which causes the straight sides of the air outlet hood to shrink toward its geometric center when the air outlet hood is constructed as a square air outlet hood, causing the buckles set on the straight sides of the air outlet hood to shift, and the buckles cannot cooperate with the buckle holes on the mounting plate. Even if the buckles are installed to the buckle holes, they are easy to fall off, affecting the assembly of the air outlet hood and the mounting plate.

[0074] The present application sets a guide rib 1232 and a guide flange 1132 whose protruding height relative to the support plate 1231 gradually increases. The guide flange 1132 can drive the guide portion 123 to move in a direction away from the guide flange 1132 through the guide rib 1232, and the guide portion 123 can drive the connecting portion 122 to move in a direction away from the geometric center of the frame 121 through the frame 121, thereby preventing the connecting portion 122 from being unable to connect and cooperate with the first mounting portion 112 due to the centripetal contraction of the frame 121.

[0075] like Figure 2 As shown, in some embodiments of the present invention, the angle between the extension direction of the guide flange 1132 and the connecting surface between the mounting plate 110 and the guide flange 1132 is a, and satisfies: 90°≤a≤135°, and when the angle is an obtuse angle, the guide flange 1132 is inclined toward the side of the second mounting hole 1131.

[0076] It should be noted that a surface of the mounting plate 110 that faces away from the air outlet cover 120 in the first direction and is connected to the guide flange 1132 is defined as a connection surface between the mounting plate 110 and the guide flange 1132 .

[0077] Specifically, the guide flange 1132 extends straight from the mounting plate 110 in a direction away from the air outlet cover 120, and a surface on one side of the guide rib 1232 that guides the guide flange 1132 is arranged parallel to the guide flange 1132, which is beneficial to increasing the guiding matching area between the guide rib 1232 and the guide flange 1132, while ensuring the guiding matching effect and dispersing the force on the guide rib 1232, preventing the guide rib 1232 from being locally subjected to large force due to the small matching area between the guide flange 1132 and the guide rib 1232, thereby preventing the guide flange 1132 from damaging the guide rib 1232 and ensuring the service life of the air outlet cover 120.

[0078] Furthermore, the guide flange 1132 and the connecting surface of the guide flange 1132 and the mounting plate 110 are arranged at an angle, and the angle is defined as a, wherein 90°≤a≤135° is conducive to ensuring the guiding cooperation effect between the guide flange 1132 and the guide rib 1232. When a<90°, the guiding cooperation effect between the guide flange 1132 and the guide rib 1232 is poor. When the angle between the guide flange 1132 and the connecting surface of the guide flange 1132 and the mounting plate 110 is an obtuse angle, The guide flange 1132 gradually inclines toward the second mounting hole 1131 from the position connected to the mounting plate 110, and when a>135°, the inclination angle of the guide flange 1132 toward the second mounting hole 1131 is too large, resulting in the guide flange 1132 occupying the space of the second mounting hole 1131, causing the guide portion 123 to be unable to pass through the second mounting hole 1131. At the same time, the guiding coordination effect between the guide flange 1132 and the guide rib 1232 is poor, affecting the assembly of the air outlet cover 120.

[0079] Reference Figure 2 In some embodiments of the present invention, a gap is formed between the surfaces on which the guide flange 1132 and the guide rib 1232 are relatively arranged. The vertical distance between the surfaces on which the guide rib 1232 and the guide flange 1132 are relatively arranged is defined as the width dimension A of the gap. Preferably, 0.2mm≤A≤1mm, wherein A≥0.2mm can ensure that the guide portion 123 can also be guided and matched with the second mounting portion 113 even when there is a dimensional error or deformation, which is beneficial to reducing the processing accuracy requirements for the guide portion 123 and reducing production costs. A≤1mm can avoid affecting the guiding and matching effect of the guide rib 1232 and the guide flange 1132 due to the excessive gap between the guide flange 1132 and the guide rib 1232.

[0080] Reference Figure 2 In some embodiments of the present invention, a gap is formed between a side surface of the support plate 1231 away from the guide rib 1232 and the inner wall surface of the second mounting hole 1131, and the vertical distance between the support plate 1231 and the inner wall surface of the second mounting hole 1131 is defined as the width dimension B of the gap, preferably, B≥2mm, to ensure that the guide portion 123 can also cooperate with the second mounting hole 1131 in the event of dimensional error or deformation, which is beneficial to reducing the processing accuracy requirements for the guide portion 123.

[0081] like Figure 2 As shown, in some embodiments of the present invention, the protruding length of the guide portion 123 relative to the frame 121 is H1, the protruding length of the connecting portion 122 relative to the frame 121 is H2, and H1>H2.

[0082] Specifically, H1>H2 can make the guide portion 123 first extend into the second mounting portion 113 and cooperate with the second mounting portion 113 for guidance, and the second mounting portion 113 can be pressed against the guide rib 1232 and move in the direction, and the guide portion 123 can drive the connecting portion 122 to move away from the geometric center of the frame 121 through the frame 121, thereby ensuring that the connecting portion 122 can also cooperate with the first mounting portion 112 after the frame 121 undergoes centripetal deformation, thereby ensuring the assembly of the air outlet cover 120 and the mounting plate 110.

[0083] Combination Figures 10 to 14 In some embodiments of the present invention, the connecting portions 122 and the guiding portions 123 are arranged at intervals along the circumferential extension direction of the frame 121; wherein the number of the connecting portions 122 is N, the number of the guiding portions 123 is 2N, and the two guiding portions 123 are respectively arranged on both sides of one connecting portion 122.

[0084] Specifically, the frame 121 can be constructed as a square frame, which includes four connection frames connected end to end, each of which is provided with a connection portion 122 and a guide portion 123, and the connection portion 122 and the guide portion 123 are arranged at intervals along the direction in which the four connection frames are connected end to end, wherein each connection frame is provided with at least one connection portion 122, and in the extension direction of the connection frame, guide portions 123 are provided on both sides of the connection portion 122 provided on each connection frame, and the spacing between the guide portions 123 and the connection portion 122 on both sides is the same, accordingly, with reference to Fig. 9 , second mounting portions 113 are disposed on both sides of the first mounting portion 112 on the mounting plate 110 .

[0085] The guiding cooperation between the guide parts 123 on both sides of the connecting part 122 and the second mounting part 113 precedes the cooperation between the connecting part 122 and the first mounting part 112. After the frame 121 undergoes centripetal deformation, the connecting frame bends in the direction close to the geometric center of the frame 121, and the guide part 123 moves toward the geometric center of the frame 121. The guide part 123 cannot cooperate with the first mounting part 112. In this case, the second mounting part 113 can press against the guide part 123 to move, and the guide parts 123 on both sides of the connecting part 122 can simultaneously drive the connecting frame to move in the direction away from the geometric center of the frame 121, so that the connecting part 122 can be opposite to the first mounting part 112, ensuring that the connecting part 122 can cooperate with the first mounting part 112, thereby ensuring that the air outlet cover 120 can be connected to the mounting plate 110.

[0086] Among them, providing guide parts 123 on both sides of the connecting part 122 with the same interval as the connecting part 122 is conducive to ensuring the resetting effect of the connecting part 122 and preventing poor matching effect between the connecting part 122 and the first mounting part 112 due to poor resetting effect on one side of the connecting part 122.

[0087] like Fig.10 As shown, in some embodiments of the present invention, the connection portions 122 on the two relatively arranged connection frames are different.

[0088] Specifically, two connecting parts 122 can be provided on each connecting frame, wherein the distance between the two connecting parts 122 on the upper connecting frame in the second direction is smaller than the distance between the two connecting parts 122 on the lower connecting frame. The installation direction of the air outlet hood 120 can be determined by the connecting parts 122 to prevent the air outlet hood 120 from being installed upside down, thereby further improving the assembly convenience of the air outlet hood 120.

[0089] Correspondingly, a first mounting portion 113 facing the connecting portion 122 is disposed on the mounting plate 110 , and the connecting portion 122 can be matched with the first mounting portion 113 .

[0090] Combination Figures 11 to 13 In some embodiments of the present invention, the guide rib 1232 is located on a side surface of the support plate 1231 close to the geometric center of the frame 121 in the thickness direction.

[0091] Specifically, when the frame 121 undergoes centripetal deformation, each connecting plate 1221 bends toward the direction close to the geometric center of the frame 121. By setting the guide rib 1232 on the inner side surface of the support plate 1231 (that is, the side surface of the support plate 1231 close to the geometric center of the frame 121 in the thickness direction) and the guide flange 1132 on the side surface of the second mounting hole 1131 that is opposite to the guide rib 1232, the connecting frame can be driven to move toward the direction away from the geometric center of the frame 121 through the guiding cooperation between the guide flange 1132 and the guide rib 1232, thereby facilitating the resetting of the connecting portion 122.

[0092] like Figure 3 As shown, in some embodiments of the present invention, the angle between the extension direction of the snap-in flange 1122 and the connecting surface between the mounting plate 110 and the snap-in flange 1122 is b, and satisfies: 90°≤b≤135°, and when the angle is an obtuse angle, the snap-in flange 1122 is inclined toward the side of the first mounting hole 1121.

[0093] It should be noted that the surface of the mounting plate 110 that is away from the air outlet cover 120 in the first direction and connected to the snap-fit ​​flange 1122 is defined as the connection surface between the mounting plate 110 and the snap-fit ​​flange 1122. Figures 6 to 9 The connection surface between the mounting plate 110 and the guide flange 1132 is spaced apart from the connection surface between the mounting plate 110 and the snap-on flange 1122 .

[0094] Specifically, the snap-fitting flange 1122 extends straight from the mounting plate 110 in a direction away from the air outlet cover 120, and the snap-fitting flange 1122 is arranged at an angle to the connecting surface between the mounting plate 110 and the snap-fitting flange 1122, and the angle is defined as b, 90°≤b≤135°, which is conducive to ensuring the snap-fitting effect between the hook 1222 and the snap-fitting flange 1122.

[0095] Among them, when b is less than 90°, the clamping effect of the hook 1222 and the clamping flange 1122 is poor, and the hook 1222 is easy to disengage from the clamping flange 1122, affecting the assembly reliability of the air outlet hood 120 and the mounting plate 110; when the angle between the clamping flange 1122 and the connecting surface of the clamping flange 1122 and the mounting plate 110 is an obtuse angle, the clamping flange 1122 is inclined from the position connected to the mounting plate 110 toward the direction of the first mounting hole 1121, and when b is greater than 135°, the inclination angle of the clamping flange 1122 toward the first mounting hole 1121 is too large, resulting in the clamping flange 1122 occupying the space of the first mounting hole 1121, resulting in the connection part 122 being unable to pass through the first mounting hole 1121, thereby resulting in the hook 1222 being unable to clamp and cooperate with the clamping flange 1122, affecting the assembly of the air outlet hood 120.

[0096] Reference Figure 3 In some embodiments of the present invention, the distance between the engaging surface of the hook 1222 and the frame 121 is H3, the thickness of the connecting plate 1221 is W, and the following condition is satisfied: 4W≤H3≤10W.

[0097] Specifically, one side surface where the hook 1222 is snap-fitted with the snap-fit ​​flange 1122 is defined as the snap-fit ​​surface of the hook 1222, the vertical distance between the position where the snap-fit ​​surface is connected to the connecting plate 1221 and the frame 121 is H3, the thickness dimension of the connecting plate 1221 is defined as W, 4W≤H3≤10W, which can ensure the elastic deformation ability of the connecting plate 1221, and during the disassembly of the air outlet hood 120 and the mounting plate 110, when the connecting part 122 is detached from the first mounting part 112, the snap-fit ​​flange 1122 will press against the hook 1222 and drive the connecting plate 1221 to undergo elastic deformation through the hook 1222, so that the connecting part 122 is easy to disengage from the first mounting part 112, thereby facilitating the disassembly of the air outlet hood 120, and when the connecting part 122 is disengaged from the first mounting part 112, the connecting part 122 can be restored to the state before being pressed against the snap-fit ​​flange 1122.

[0098] At the same time, 4W≤H3≤10W can effectively ensure the structural strength of the connecting plate 1221 and prevent the connecting plate 1221 from breaking or turning white due to insufficient elasticity when the connecting flange 1122 drives the connecting plate 1221 to deform.

[0099] Among them, when H3 is less than 4W, the elasticity of the connecting plate 1221 is poor, and the effect of the snap-fit ​​flange 1122 driving the connecting plate 1221 to deform is poor, which makes it difficult for the connecting portion 122 to disengage from the first mounting portion 112 and for the air outlet hood 120 to be disassembled; when H3 is greater than 10W, the structural strength of the connecting plate 1221 is poor, and when the snap-fit ​​flange 1122 presses against the connecting portion 122, the connecting plate 1221 is prone to breakage or whitening.

[0100] Reference Figure 3 In some embodiments of the present invention, the hook 1222 is provided with a clamping surface, and the angle between the clamping surface and the extension direction of the connecting plate 1221 is c, and satisfies: 90°≤c≤135°.

[0101] Specifically, the side surface where the hook 1222 is snap-fitted with the snap-fit ​​flange 1122 is defined as the snap-fit ​​surface of the hook 1222, and the angle between the side surface of the connecting plate 1221 connected to the hook 1222 in the thickness direction and the snap-fit ​​surface is c, 90°≤c≤135°, which is conducive to ensuring the reliability of the snap-fit ​​between the hook 1222 and the snap-fit ​​flange 1122, preventing the connection part 122 from being disengaged from the first mounting part 112 due to the poor snap-fit ​​effect between the hook 1222 and the snap-fit ​​flange 1122, and ensuring the assembly reliability of the air outlet hood 120 and the mounting plate 110.

[0102] like Figure 3 As shown, in some embodiments of the present invention, the protrusion height of the engaging surface of the hook 1222 relative to the connecting plate 1221 is L1, and L1≥0.5 mm.

[0103] Specifically, the hook 1222 is arranged on one side surface of the connecting plate 1221 in the thickness direction, and in the thickness direction of the connecting plate 1221, the hook 1222 protrudes in the direction away from the connecting plate 1221, and the vertical distance between the highest point of the protrusion of the hook 1222 and the connecting plate 1221 is L1, L1≥0.5mm, which is conducive to ensuring the matching reliability of the hook 1222 and the snap-on flange 1122, reducing the possibility of the hook 1222 being separated from the snap-on flange 1122, and effectively ensuring that the hook 1222 and the mounting plate 110 have sufficient snap fit, thereby ensuring the matching reliability of the air outlet hood 120 and the mounting plate 110.

[0104] When L1 is less than 0.5 mm, the engagement amount between the hook 1222 and the mounting plate 110 is small, and the hook 1222 is easily disengaged from the mounting plate 110 , resulting in poor assembly reliability between the air outlet cover 120 and the mounting plate 110 .

[0105] like Figure 3As shown, in some embodiments of the present invention, the first mounting hole 1121 and the second mounting hole 1131 can be constructed as oblong holes, and the extension direction of the oblong hole on each connecting frame is the same as the extension direction of the connecting frame, wherein the dimension of the first mounting hole 1121 in a direction parallel to the thickness direction of the connecting plate 1221 is the width dimension D of the first mounting hole 1121, and the thickness dimension of the connecting portion 122 is defined as G, D≥G, to ensure that the connecting portion 122 can extend into the first mounting hole 1121, so as to facilitate the snap-fitting of the connecting portion 122 with the snap-fit ​​flange 1122.

[0106] Combination Fig.10 , Fig.12 and Fig.13 In some embodiments of the present invention, a support protrusion 1211 is provided on a surface of the frame 121 opposite to the mounting plate 110 , and the support protrusion 1211 is supported between the frame 121 and the mounting plate 110 .

[0107] Specifically, each connecting frame is provided with a supporting protrusion 1211, which protrudes from the frame 121 to one side of the mounting plate 110 along the first direction, and the supporting protrusion 1211 is spaced apart from the connecting portion 122 and the guide portion 123. When the frame 121 is assembled to the mounting plate 110, the supporting protrusion 1211 is supported between the frame 121 and the mounting plate 110 in the first direction, so that the surface of the frame 121 opposite to the mounting plate 110 is spaced apart. The frame 121 is supported on the mounting plate 110 by the supporting protrusion 1211 to reduce the contact area between the frame 121 and the mounting plate 110, thereby effectively reducing the vibration and friction noise between the frame 121 and the mounting plate 110 when the air conditioner is running.

[0108] In addition, the frame 121 is connected to the mounting plate 110 via threaded connectors such as screws to further ensure the assembly reliability of the air outlet cover 120 and the mounting plate 110 .

[0109] Reference Fig.14 In some embodiments of the present invention, the protruding height of the supporting protrusion 1211 is L2, and L2≥1mm.

[0110] Specifically, the vertical distance between the side surface of the support protrusion 1211 away from the frame 121 in the first direction and the frame 121 is defined as the height L2 of the support protrusion 1211. Figure 2 and Figure 3The vertical distance C between the surface of the frame 121 on the side opposite to the mounting plate 110 in the first direction and the mounting plate 110 is the same as the protruding height L2 of the support protrusion 1211, where L2 ≥ 1mm, to ensure that the frame 121 is spaced apart from the mounting plate 110 in the event of deformation or dimensional error during production, thereby reducing the contact area between the frame 121 and the mounting plate 110 and effectively reducing the vibration and friction noise between the frame 121 and the mounting plate 110 when the air conditioner is running.

[0112] Since the air conditioner casing is provided with the above-mentioned air outlet cover assembly 100, a guide portion 123 is provided on the air outlet cover 120, and the cooperation between the guide portion 123 and the second mounting portion 113 precedes the cooperation between the connecting portion 122 and the first mounting portion 112, so as to play a role in positioning and installing the air outlet cover 120 and the mounting plate 110. At the same time, the guide portion 123 can guide the installation of the air outlet cover 120, effectively improve the cooperation accuracy between the connecting portion 122 and the first mounting portion 112, ensure that the connecting portion 122 can be connected to the first mounting portion 112, and effectively improve the assembly convenience of the air outlet cover 120.

[0113] The air conditioner according to the present invention comprises the above-mentioned air conditioner casing.

[0114] Since the air conditioner is provided with the above-mentioned air conditioner casing, a guide portion 123 is provided on the air outlet cover 120, and the cooperation between the guide portion 123 and the second mounting portion 113 precedes the cooperation between the connecting portion 122 and the first mounting portion 112, so as to play a role in positioning and installing the air outlet cover 120 and the mounting plate 110. At the same time, the guide portion 123 can guide the installation of the air outlet cover 120, effectively improve the cooperation accuracy between the connecting portion 122 and the first mounting portion 112, ensure that the connecting portion 122 can be connected to the first mounting portion 112, and effectively improve the assembly convenience of the air outlet cover 120.
