[0059] For example, the electric control box component 20 includes a mainboard bracket 47 , which is disposed in the electric control box 21 and is used to fix and support the main control board 22 .

[0060] The electric control box 21 includes a box body 23 and a box cover 24. The upper side of the box body 23 is open to form an opening 25 facing the top cover 12. The box cover 24 is connected to the box body 23 and can open or close the opening 25. By setting the opening 25 of the electric control box 21 to face the top cover 12, when the box cover 24 of the electric control box 21 needs to be opened, only the top cover 12 needs to be opened, and the front panel 14 does not need to be opened, thereby reducing the operation steps and the difficulty of operation.

[0061] When the maintenance personnel need to repair the air conditioner indoor unit 100, they need to open the top cover 12 first, and then open the box cover 24 of the electric control box 21 to carry out the maintenance. When the maintenance personnel finish the maintenance and need to restore the air conditioner, they need to close the box cover 24 of the electric control box 21 first, and then close the top cover 12. During the maintenance and restoration process, only the box cover 24 and the top cover 12 need to be opened or closed, and there is no need to disassemble the front panel 14. This can avoid damage caused by disassembling the front panel 14. The components or wiring on the front panel 14 are complicated and cannot be restored. The maintenance personnel have fewer operation steps and the operation difficulty is low.

[0063] According to the air conditioner of the embodiment of the utility model, the electric control box 21 is set to be open on the upper side of the box body 23 to form an upward opening 25, and the box cover 24 is connected to the box body 23 and the opening 25 can be opened or closed. When maintaining or repairing the electric control box component 20, the top cover 12 on the casing 10 is removed, and the box cover 24 of the electric control box 21 is opened, and the electric control box component 20 can be maintained or repaired (for example, the main control board 22 can be maintained or repaired). There is no need to remove the front panel 14 on the casing 10 to achieve maintenance or repair of the electric control box component 20, which simplifies the maintenance or repair operation process of the electric control box component 20, reduces the difficulty of maintenance or repair of the electric control box component 20, and can also avoid the impact on the performance of the whole machine caused by the components and wiring on the front panel 14 that cannot be restored or damaged due to the disassembly of the front panel 14.

[0064] According to some embodiments of the present invention, reference Figure 3 , the box cover 24 can rotate relative to the box body 23 to open or close the opening 25. By making the box cover 24 be arranged to rotate relative to the box body 23, by rotating the box cover 24, the opening and closing of the opening 25 on the box body 23 is made more convenient.

[0065] According to some embodiments of the present invention, reference Fig.14 The air conditioner includes a fixing assembly 26, and when the box cover 24 is at the position of opening the opening 25, the fixing assembly 26 is used to fix the box cover 24 at the position of opening the opening 25. When the box cover 24 is at the position of opening the opening 25, by fixing the box cover 24 at the position of opening the opening 25 using the fixing assembly 26, it is possible to prevent the box cover 24 from falling unstably when the box cover 24 is at the position of opening the opening 25, thereby harming people or other parts, thereby ensuring the safety of the user. In addition, by fixing the box cover 24 at the position of opening the opening 25 by the fixing assembly 26, it is also possible to prevent the box cover 24 from rotating in the opposite direction to the position of closing the opening 25 under its own gravity, thereby facilitating the maintenance or repair of the components in the electric control box 21, such as the main control board 22.

[0066] According to some embodiments of the present invention, reference Fig.14 The fixing assembly 26 fixes the box cover 24 at the position of opening the opening 25 by magnetic attraction. The box cover 24 is fixed at the position of opening the opening 25 by magnetic attraction. This fixing method is simple and can make the box cover 24 more reliably fixed at the position of opening the opening 25, thereby preventing the box cover 24 from falling unstably when it is at the position of opening the opening 25.

[0067] According to some embodiments of the present invention, reference Fig.14The fixing assembly 26 includes a first magnetic member 27, and the first magnetic member 27 is arranged on the box body 23 or the shell 11. For example, the first magnetic member 27 can be arranged on the inner side wall of the shell 11 or the outer side wall of the box body 23, and the first magnetic member 27 can be fixed to the box body 23 or the shell 11 by bonding. At least part of the box cover 24 is made of a material that is attracted to the first magnetic member 27. For example, a part of the box cover 24 can be made of a material that is attracted to the first magnetic member 27. When the box cover 24 is in a position to open the opening 25 of the box body 23, the part of the box cover 24 made of the material that is attracted to the first magnetic member 27 is attracted to the first magnetic member 27. For another example, the entire box cover 24 can also be made of a material that is attracted to the first magnetic member 27. When the box cover 24 is in a position to open the opening 25 of the box body 23, the box cover 24 is attracted to the first magnetic member 27. For example, the box cover 24 can be a metal part. By making at least a portion of the box cover 24 of a material that is attracted to the first magnetic member 27, the box cover 24 itself can have a magnetic attraction with the first magnetic member 27, eliminating the need for a separate component installed on the box cover 24 for magnetic attraction to the first magnetic member 27.

[0068] According to other embodiments of the utility model, the fixing assembly 26 includes a first magnetic member 27 and a second magnetic member that attract each other. The first magnetic member 27 is provided on the box body 23 or the shell 11, and the second magnetic member is provided on the box cover 24. The second magnetic member can be adhesively fixed to the box cover 24, for example, the second magnetic member can be provided on the outer surface of the box cover 24. When the box cover 24 is in the position of opening the opening 25, the second magnetic member is opposite to and attracted to the first magnetic member 27. By providing the first magnetic member 27 on the box body 23 or the shell 11, and the second magnetic member on the box cover 24, when the box cover 24 is in the position of opening the opening 25, the first magnetic member 27 and the second magnetic member are attracted to each other, so that the fixing of the box cover 24 can be made more firm and stable. In addition, by separately providing the second magnetic member on the box cover 24, the second magnetic member can be provided at a suitable position as needed, so that the setting position of the second magnetic member on the box cover 24 is more flexible.

[0069] According to some embodiments of the present invention, reference Fig.13 and Fig.14 When the box cover 24 is at the position of opening the opening 25, the box cover 24 is placed in the up-down direction. By placing the box cover 24 in the up-down direction when the box cover 24 is at the position of opening the opening 25, it is possible to save space when the box cover 24 is opened, and to avoid scratches and damage to people or other parts caused by the part of the box cover 24 located on the outer peripheral side of the housing 10 when the box cover 24 is opened. In addition, it is also possible to avoid interference between the box cover 24 and the housing 10 or other parts.

[0070] According to some embodiments of the present invention, reference Fig.13When the box cover 24 is at the position of opening the opening 25, the box cover 24 is placed in the up-down direction, and the box cover 24 is located on the left or right side of the box body 23. Usually, the user places the rear side of the air conditioner against the wall. If the box cover 24 is located at the front side of the box body 23, when the box cover 24 is opened, the box cover 24 interferes with the user's line of sight and hinders maintenance. The user needs to go around the back of the air conditioner for maintenance, and it is necessary to reserve space for the rear of the air conditioner in advance, which is more cumbersome; if the box cover 24 is located at the rear side of the box body 23, when the box cover 24 is opened, the box cover 24 may interfere with the wall and cause the box cover 24 to be not opened in place, and the box cover 24 not being opened in place will also affect the convenience of maintaining the electric control box component 20. By making the box cover 24 located on the left or right side of the box body 23 when the box cover 24 is at the position of opening the opening 25, it can be avoided that the box cover 24 interferes with the user's line of sight and hinders maintenance when it is opened, so that the maintenance or repair of the electric control box component 20 is more convenient, and the problem of interference between the box cover 24 and the wall causing the box cover 24 to be not opened in place can also be avoided.

[0071] According to some embodiments of the present invention, reference Figure 3 and Fig.13 , one end of the box cover 24 is rotatably connected to the box body 23, and the other end of the box cover 24 is detachably connected to the box body 23. For example, one end of the box cover 24 is connected to the box body 23 via a hinge 49, and the box cover 24 can rotate relative to the box body 23 around the hinge 49; the other end of the box cover 24 relative to the hinge 49 is detachably connected to the box body 23. When opening the box cover 24, the connection between the other end of the box cover 24 and the box body 23 can be released first, and then the box cover 24 can be rotated upward to a position where the opening 25 is opened; when closing the box cover 24, the box cover 24 can be rotated downward to a position where the opening 25 is closed, and the other end of the box cover 24 is connected to the box body 23. The above-mentioned connection method between the box cover 24 and the box body 23 not only makes the opening or closing operation of the box cover 24 relatively simple, but also when the box cover 24 is in the position of closing the opening 25, since the other end of the box cover 24 is connected to the box body 23, the box cover 24 can be locked in the position of closing the opening 25.

[0072] According to some embodiments of the present invention, reference Fig.10 and Fig.11 , the other end of the box cover 24 is connected to the box cover 24 through a buckle structure 29. For example, the buckle structure 29 includes a first buckle structure 30 and a second buckle structure 31, the first buckle structure 30 is provided on the box cover 24, and the second buckle structure 31 is provided on the box body 23. By matching the first buckle structure 30 and the second buckle structure 31, the box cover 24 can be fully fixed when it is in the position of covering the upper opening 25.

[0073] For example, the first snap-fit ​​structure 30 includes a first snap-fit ​​groove, and the second snap-fit ​​structure 31 includes a first snap-fit ​​protrusion. When the box cover 24 covers the opening 25 , the first snap-fit ​​protrusion is accommodated in the first snap-fit ​​groove, so that the box cover 24 is limited relative to the box body 23 .

[0074] Optionally, the first clamping structure 30 includes a plurality of first clamping grooves, and the second clamping structure 31 includes a plurality of first clamping protrusions corresponding to the first clamping grooves. Fig.10 and Fig.11 The first snap-fitting structure 30 includes two first snap-fitting grooves, and correspondingly, the second snap-fitting structure 31 includes two first snap-fitting protrusions. When the box cover 24 is in the position of covering the open opening 25, multiple first snap-fitting protrusions are accommodated in multiple first snap-fitting grooves, so that the box cover 24 is more fully limited.

[0075] According to some embodiments of the present invention, reference Fig.14 The inner wall of the housing 11 is provided with a support boss 32, which can be integrally formed with the housing 11, or fixed to the inner wall of the housing 11 by adhesive or fasteners. When the box cover 24 is at the position of opening the opening 25, the box cover 24 is supported on the support boss 32. By using the support boss 32 to support the box cover 24, the box cover 24 can be stably maintained at the position of opening the opening 25, and the box cover 24 can be prevented from tilting.
