[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0034] The embodiment of the present application provides a mounting cover to solve the problem of complicated assembly and disassembly of the motor 9 cover.

[0035] In the embodiments of this application, Figure 1 、 Figure 2 and Figure 3 As shown, the mounting cover is provided with a mounting cavity 3, a clamping portion 4 and a first fastening portion 5; the clamping portion 4 and the first fastening portion 5 are located at opposite ends of the mounting cavity 3 along a first direction, the first direction is perpendicular or inclined to the axial direction of the motor 9, the clamping portion 4 is used to clamp with the base 8; the first fastening portion 5 is used to be fastened to the fastener; the mounting cavity 3 is used to accommodate the motor 9, and the center of the motor 9 is located in the middle of the clamping portion 4 and the first fastening portion 5, or between the middle of the clamping portion 4 and the first fastening portion 5 and the first fastening portion 5.

[0036] It should be noted that the installation cavity 3 is partially enclosed by the installation cover. The installation cover includes an integrally formed arc-shaped cover 1 and two side stops 2. The arc-shaped cover 1 and the two side stops 2 enclose the installation cavity 3. A fastener refers to a structure used to connect two or more parts into a whole. In this embodiment, the fastener is used to connect the installation cover to the base 8. The fastener can be a bolt, a stud, a screw, etc. The center of the motor 9 refers to the geometric center of the motor 9. Usually, the motor 9 adopts an axially symmetrical design. Therefore, the geometric center of the motor 9 is also the center of gravity of the motor 9. The shape of the installation cavity 3 is also adapted to the shape of the motor 9 accordingly. The center of the motor 9 is also the center of the installation cavity 3. The base 8 refers to the base 8 on the air-conditioning indoor unit, and the motor 9 refers to the structure that drives the cross-flow fan 10 of the air-conditioning indoor unit. In the first direction or the second direction, the center of the motor 9 is unchanged.

[0037] It can be understood that by arranging the clamping portion 4 and the first fastening portion 5 near the mounting cavity 3, and making the center portion of the motor 9 between the clamping portion 4 and the first fastening portion 5, the motor 9 has better fastening force at both opposite ends along the first direction; and further making the center portion of the motor 9 close to the first fastening portion 5, so that the first fastening portion 5 provides a greater fastening force for the center portion of the motor 9 than the clamping portion 4, thereby reducing the use of screws in related technologies while ensuring better fixing stability.

[0038] In some embodiments, the mounting cover includes an integrally formed arcuate cover 1, two side stops 2, and a shielding portion 7. The arcuate cover 1 and the two side stops 2 enclose a mounting cavity 3. The shielding portion 7 is connected to the circumference of the arcuate cover 1 and the two side stops 2, and the first fastening portion 5 is disposed on the shielding portion 7. It will be understood that the two side stops 2 are located in the second direction and correspond one-to-one to the two axial ends of the motor 9.

[0039] In some embodiments, as Figure 4 and Figure 5 As shown, the axial direction of the motor 9 is the second direction, and the first direction is perpendicular to the second direction;

[0040] Along the second direction, the distance between the center of the motor 9 and the first fastening portion 5 is less than or equal to the distance between the center of the motor 9 and the clamping portion 4; along the first direction, the distance between the center of the motor 9 and the first fastening portion 5 is less than or equal to the distance between the center of the motor 9 and the clamping portion 4.

[0041] It is understood that the center of the motor 9 is located at the center between the clamping portion 4 and the first fastening portion 5. More preferably, along the first and second directions, the center of the motor 9 is located closer to the first fastening portion 5 than the clamping portion 4. In other words, the straight-line distance between the center of the motor 9 and the first fastening portion 5 is smaller than the straight-line distance between the center of the motor 9 and the clamping portion 4. This improves the fixing stability of the mounting cover from different directions.

[0042] For example, along the first direction, the linear distance between the first fastening portion 5 and the clamping portion 4 is v, and the distance between the center of the motor 9 and the first fastening portion 5 is L2, where 0.3v≤L2≤0.5v. Along the second direction, the linear distance between the first fastening portion 5 and the end of the clamping portion 4 away from the first fastening portion 5 is w, and the distance between the center of the motor 9 and the first fastening portion 5 is L1, where 0.3w≤L1≤0.5w.

[0043] In some embodiments, as Figure 4 and Figure 5 As shown, along the second direction, the clamping portion 4 extends toward one end of the first fastening portion 5 and toward the first fastening portion 5 .

[0044] It should be noted that the clamping portion 4 extends in the second direction and is clamped to the base 8 in the first direction. It is understood that by extending the end of the clamping portion 4 toward the first fastening portion 5, the end of the clamping portion 4 away from the first fastening portion 5 in the second direction is less likely to vibrate under the fastening force of the first fastening portion 5, thereby further improving the fixing stability.

[0045] Exemplarily, along the second direction, a distance between the first fastening portion 5 and an end of the clamping portion 4 facing the first fastening portion 5 is m, where 0≤m≤3mm.

[0046] In some embodiments, as Figure 4 and Figure 5 As shown, the mounting cover is further provided with a second fastening portion 6, which is used to fix the power control box.

[0047] It should be noted that the second fastening portion 6 is located on the shielding portion 7 and provides a mounting location for the electric control box, thereby achieving secure installation of the electric control box. It is understood that fasteners are used to connect the electric control box and the second fastening portion 6 as a whole. The fasteners can be bolts, studs, screws, etc.

[0048] In some embodiments, as Figure 4 and Figure 5 As shown, along the second direction, the second fastening portion 6 is located between the clamping portion 4 and the first fastening portion 5, and the distance between the end of the clamping portion 4 facing the first fastening portion 5 and the second fastening portion 6 is less than or equal to the distance between the end of the clamping portion 4 away from the first fastening portion 5 and the second fastening portion 6.

[0049] It is understood that the second fastening portion 6 is preferably closer to the end of the clipping portion 4 facing the first fastening portion 5 than to the end of the clipping portion 4 facing away from the first fastening portion 5, or the second fastening portion 6 is located at the center of the clipping portion 4. Alternatively, along the second direction, the second fastening portion 6 is located between the first fastening portion 5 and the end of the clipping portion 4 facing the first fastening portion 5. This prevents the electrical control box from pulling the end of the clipping portion 4 facing away from the first fastening portion 5, thus ensuring that the mounting cover is not easily deformed or tilted.

[0050] Illustratively, along the second direction, when the second fastening portion 6 is located at the center of the clamping portion 4, the distance between the second fastening portion 6 and one end of the clamping portion 4 facing the first fastening portion 5 is L3, and the length between the opposite ends of the clamping portion 4 is s, 0.3s≤L3≤0.5s.

[0051] In some embodiments, as Figure 5As shown, along the first direction, the second fastening portion 6 is located between the first fastening portion 5 and the clamping portion 4 , and the distance between the second fastening portion 6 and the first fastening portion 5 is greater than the distance between the second fastening portion 6 and the clamping portion 4 .

[0052] It is understood that, along the first direction, the linear distance between the second fastening portion 6 and the clamping portion 4 is smaller than the linear distance between the second fastening portion 6 and the first fastening portion 5. When the electric control box is mounted on the second fastening portion 6, the electric control box's own gravity suppresses vibration of the clamping portion 4 and prevents the end of the mounting cover near the clamping portion 4 from tilting.

[0053] In some embodiments, as Figure 5 As shown, both the first fastening portion 5 and the second fastening portion 6 are provided with threaded holes for fasteners to pass through, and the threaded holes of the first fastening portion 5 and the threaded holes of the second fastening portion 6 extend in different directions.

[0054] In some embodiments, as Figure 5 As shown, the mounting cover is further provided with a wire groove 71 located on the peripheral side of the second fastening portion 6 , and the wire groove 71 is used to connect the line of the power supply 9 to the electric control box.

[0055] It should be noted that the wire groove 71 is communicated with the installation cavity 3. In this way, the line connecting the motor 9 to the electric control box can be shortened to avoid excessive exposure of wires.

[0056] In some embodiments, as Figure 5 、 Figure 10 and Figure 11 As shown, the installation cover is provided with a plurality of water guide portions 72 , at least one water guide portion 72 is located on the upper side of the installation cover and on the peripheral side of the first fastening portion 5 , and at least one water guide portion 72 is located on the lower side of the installation cover.

[0057] It should be noted that the upper side and lower side of the mounting cover refer to the upper and lower sides of the mounting cover in terms of spatial location. The water guide portion 72 is a rib structure protruding from the surface of the mounting cover. One water guide portion 72 specifically protrudes from the upper side of the shielding portion 7, and the other water guide portion 72 specifically protrudes from the lower side of the shielding portion 7. The rib structure guides the water flow from the shielding portion 7 and drains it away, reducing condensation residue and wall buildup on the mounting cover.

[0058] In some embodiments, as Figure 9 、 Figure 10 and Figure 11 As shown, the water guide portion 72 located at the lower side of the shielding portion 7 is located just above the water receiving portion 83 of the base 8. In this way, the condensed water is collected in the water receiving portion 83 and then discharged uniformly, avoiding the condensed water from being retained in the installation cavity 3.

[0059] In some embodiments, along the second direction, the distance between the center of the motor 9 and the first fastening portion 5 is L1, and the distance between the center of the motor 9 and the clamping portion 4 is w, 0.3w≤L1<0.5w;

[0060] Along the first direction, the distance between the center of the motor 9 and the first fastening portion 5 is L2, and the distance between the center of the motor 9 and the clamping portion 4 is v, 0.3v≤L2<0.5v;

[0061] Along the second direction, the second fastening portion 6 is located between the clamping portion 4 and the first fastening portion 5, the distance between the second fastening portion 6 and one end of the clamping portion 4 facing the first fastening portion 5 is L3, and the distance between the opposite ends of the clamping portion 4 is s, 0.3s≤L3<0.5s.

[0062] By using the above distance range, the stability of the mounting cover on the base 8 can be comprehensively improved.

[0063] In some embodiments, as Figure 3 As shown, the first fastening portion 5 protrudes from the upper side of the mounting cover. The first fastening portion 5 is provided with a first fixing hole 51 and a notch 52 located around the first fixing hole 51 . The notch 52 exposes the first fixing hole 51 .

[0064] It should be noted that the first fixing hole 51 is a threaded hole, and the first fastening part 5 protrudes from the upper side of the shielding part 7 so that the accumulated water on the shielding part 7 is not easy to flow into the threaded hole of the first fastening part 5, thereby avoiding rusting of the fastener, extending the service life of the fastener, and improving the fixing reliability of the installation cover.

[0065] It is understandable that the notch 52 is used to provide space for the fastener to be screwed, thereby facilitating quick disassembly and assembly.

[0066] In some specific embodiments, the end of the first fixing hole 51 is recessed at the end of the first fastening portion 5 away from the shielding portion 7. In this way, at least a portion of the first fastening portion 5 located around the notch 52 provides a physical barrier to the first fixing hole 51, preventing condensation water from flowing into the first fixing hole 51.

[0067] In some embodiments, as Figure 3 As shown, the wire groove 71 is located on the shielding portion 7.

[0068] An embodiment of the present application also provides an air-conditioning indoor unit, which includes a base 8, an electrical control box, a motor 9 and the installation cover as described above. The specific structure of the installation cover refers to the above embodiment. Since this air-conditioning indoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0069] like Figure 6 、 Figure 7 and Figure 8 As shown, the base 8 is provided with a bayonet 81 and a water receiving portion 83. The bayonet 81 is snap-connected to the snap-connecting portion 4. The fastener passes through the first fastening portion 5 and the connecting portion 82. The water receiving portion 83 is spaced apart below the bayonet 81 and the connecting portion 82.

[0070] It is understandable that by providing the first fastening portion 5 and the clamping portion 4 with the bayonet 81 and the connecting portion 82 away from the water receiving portion 83 , the water receiving portion 83 is prevented from being pierced when the mounting cover is mounted to the base 8 .

[0071] In the above embodiments, the descriptions of each embodiment have their own emphasis. For parts not described in detail in a particular embodiment, please refer to the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope.
