[0053] 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.

[0054] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0055] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0056] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0057] See also Figures 1 to 4 In the related art, an air conditioner outdoor unit 200 is proposed, including a shell assembly 40, a middle partition 60 arranged in the shell assembly 40, an electric control box 50, a compressor and a condenser. The shell assembly 40 generally includes a top cover 43, a bottom plate 45, a front panel 41, a rear panel (not shown) and a first side panel 42 and a second side panel 44. The middle partition 60 divides the internal space of the shell assembly 40 formed by the top cover 43, the bottom plate 45, the front panel 41, the rear panel and the first side panel 42 and the second side panel 44 into a mechanical space and a heat exchange space. The condenser is arranged in the heat exchange space, and the electric control box 50 is at least partially arranged in the mechanical space and is respectively connected to the front panel 41 and the middle partition 60.

[0058] As shown in the background art, in the prior art, when the electric control box 50 inside the housing assembly 40 needs to be removed for maintenance, first, the top cover 43 needs to be removed. Figure 1 After removing the fixing screws at a1, a2, a3, and a4 on the top cover 43, the top cover 43 is removed. At this time, the fixed connection position of the middle partition 60 and the electric control box 50 is still not exposed. At this time, the front panel 41 needs to be removed, such as Figure 2 and Figure 3 After removing the fixing screws at a5, a6, a7, a8, and a9 on the front panel 41, the front panel 41 is removed. At this time, the following is formed: Figure 4 , remove the electric control box 50 from the middle partition 60. For example, after removing the fixing screws at a10 of the middle partition 60, the electric control box 50 can be completely taken out.

[0059] It should be noted that a1, a2, a3, a4, a5, a6, a7, a8, a9, and a10 represent ten operating positions, and each position is provided with a fixing screw, but it does not mean that there is only one screw at each position. There can be multiple screws or one screw. Maintenance personnel need to operate the connection relationships at the ten positions one by one.

[0060] When the electric control box 50 needs to be repaired, the top cover 43 and the front panel 41 need to be removed before the electric control box 50 can be removed for inspection or replacement. The housing assembly 40 that needs to be removed has many parts, and the maintenance efficiency is low. In addition, since the removal of the top cover 43 and the front panel 41 requires removing multiple fixing screws and removing the top cover 43 and the front panel 41 from the air conditioner outdoor unit 200, the maintenance operation is also difficult, and the maintenance personnel need to remove multiple parts and carry the top cover 43 and the front panel 41 back and forth.

[0061] Based on this, the present application provides an air-conditioning outdoor unit 100, which is provided with an electric control box 30, and the electric control box 30 in the air-conditioning outdoor unit 100 can be quickly and conveniently repaired. Specifically, the air-conditioning outdoor unit 100 provided in the present application includes a shell assembly 10, a middle partition 20 and an electric control box 30. The shell assembly 10 includes an outer shell 12 and a top cover 11. One side of the outer shell 12 has an opening 121. The top cover 11 covers the opening 121 and is detachably connected to the outer shell 12. The middle partition 20 is arranged in the shell assembly 10 and is connected to the top cover 11 and the outer shell 12 to form a mechanical space 22 connected to the opening 121. The electric control box 30 is at least partially assembled in the mechanical space 22, wherein the electric control box 30 has a first matching portion 31, the middle partition 20 has a second matching portion 21, the first matching portion 31 is slidably matched with the second matching portion 21, and the electric control box 30 is configured to be able to slide relative to the middle partition 20 under the action of external force and detach from the mechanical space 22 from the opening 121 when at least part of the opening 121 is opened.

[0062] The middle partition 20 is disposed in the housing assembly 10 and can be used to separate a mechanical space 22 in the housing assembly 10. Figure 5 When the top cover 11 closes the opening 121, the mechanical space 22 is closed, and the housing assembly 10 has a complete appearance. Figure 7 When the top cover 11 partially or completely opens the opening 121 , the mechanical space 22 is opened. At this time, the electric control box 30 can be exposed so that maintenance personnel can approach the electric control box 30 from one side of the opening 121 .

[0063] Specifically, the middle partition 20 is arranged in the shell assembly 10 to separate the shell assembly 10 into a mechanical space 22 and a heat exchange space 23. Generally, heat exchange components such as a condenser are arranged in the heat exchange space 23, and a compressor and an electric control box 30 are placed in the mechanical space 22. Among them, the electric control box 30 can be completely arranged in the mechanical space 22 and detachably connected to the middle partition 20, or it can be partially arranged in the mechanical space 22 and the rest arranged in the heat exchange space 23.

[0064] It can be understood that in actual operation, the top cover 11 can be connected to one side of the shell assembly 10 to form a rotatable connection. When the fixation of all other positions is removed, the top cover 11 can be rotated relative to the shell assembly 10 to partially open the opening 121. In other embodiments, the top cover 11 can also be configured to be spliced ​​with multiple split structures, the multiple split structures are connected to each other, and each split structure is detachably connected to the shell assembly 10. At least one of the split structures is removed to open at least part of the opening 121.

[0065] The housing assembly 10 generally has a rectangular shape in overall appearance, and an exhaust port is formed on one side of the outer housing 12, so that the airflow generated by the air conditioner outdoor unit 100 is discharged from the outer housing 12. It can be understood that the outer housing 12 may include conventional components, such as a bottom plate 127 facing the top cover 11, a first side plate 125, a second side plate 126 facing the first side plate 125, a front panel 123, and a rear panel (not shown) facing the front panel 123. Generally, the exhaust port is provided on the front panel 123.

[0066] If a person stands in front of the front panel 123, the exhaust port blows air directly toward the person, the first side panel 125 and the second side panel 126 are located on the left and right sides of the person, and the top cover 11 and the bottom plate 127 are located at the top and bottom of the person.

[0067] The cooperation of the first matching portion 31 and the second matching portion 21 enables the electric control box 30 to be forced to slide relative to the middle partition plate 20 along a certain set direction and then separate from it, and leave the mechanical space 22 from the opening 121. Figure 7 FIG. 1 shows the direction in which the electric control box 30 needs to slide during the disassembly process of an embodiment, so that the disassembly process between the electric control box 30 and the middle partition plate 20 forms a sliding separation.

[0068] In a specific embodiment, the disassembly process of the electric control box 30 is as follows: first, the complete housing assembly 10 is removed, the top cover 11 is removed from the outer housing 12, and then the housing assembly 10 is removed from the upper cover 11. Figure 6 Switch to Figure 7The top cover 11 can be removed by removing the fixing screws at d1, d2, d3, and d4 on the top cover 11. After the top cover 11 is removed, the entire opening 121 is exposed. At this time, the fixed connection position of the middle partition 20 and the electric control box 30 is still not exposed and is blocked by the outer shell 12. Then, an external force is applied to the electric control box 30, such as Figure 7 As shown, the arrow can also be the direction of the external force applied by the maintenance personnel, so that the electric control box 30 drives the first matching part 31 to slide relative to the second matching part 21 and then leaves the original assembly position, thereby leaving the mechanical space 22 from the opening 121 and achieving separation from the middle partition 20.

[0069] In the above-mentioned disassembly process, only the top cover 11 needs to be removed, and the outer shell 12 does not need to be removed, nor does it need to expose the mating position of the first mating part 31 and the second mating part 21. The outer shell 12 can be set to be an integral assembly without a detachable connection. Even if the outer shell 12 is detachably connected, the front panel 123 still maintains a connection relationship with the chassis 127. After the top cover 11 is removed and the opening 121 is opened, the maintenance personnel can apply external force to the electric control box 30 on one side of the top cover 11 to separate the mating position of the electric control box 30 and the middle partition 20.

[0070] In other embodiments, the top cover 11 may be arranged so that the opening 121 can be partially opened, so that the electric control box 20 can leave the mechanical space 22 from the partially opened opening 121. The specific arrangement method and the size of the opening 121 are not limited in this application.

[0071] In this way, the air conditioner outdoor unit 100 provided in the present application has a simplified assembly structure. When the electric control box 30 is disassembled for after-sales maintenance, it only needs to partially or completely open the opening 121, and the electric control box 30 can be easily disassembled through the sliding cooperation of the first matching part 31 and the second matching part 21, so as to easily take out the electric control box 30, thereby improving the disassembly efficiency and reducing the difficulty of disassembly.

[0072] In one embodiment, see Figures 8 to 11 The second matching portion 21 has an initial position 213 and a target position 214. The first matching portion 31 is constructed to be able to slide between the initial position 213 and the target position 214. When the first matching portion 31 is in the initial position 213, the electric control box 30 can be forced to separate from the mechanical space 22 along the first direction L1. The first direction L1 intersects with the plane where the opening 121 is located. When the first matching portion 31 is in the target position 214, the electric control box 30 is at least partially fixed in the mechanical space 22.

[0073] The target position 214 corresponds to the final assembly position of the electric control box 30 in the housing assembly 10, and the initial position 213 corresponds to the final separation position of the electric control box 30 from the middle partition 20 in the mechanical space 22, or the first position for assembling the electric control box 30 and the middle partition 20. When the electric control box 30 needs to be assembled, the complete assembly process is to insert the electric control box 30 into the mechanical space 22 from the opening 121 along the first direction L1, and then move from the first position to the final assembly position, fix the position, and install the top cover 11.

[0074] When the electric control box 30 needs to be disassembled, the complete assembly process is to open at least part of the opening 121, apply external force to move the electric control box 30 from the final assembly position to the separation position, and then detach from the mechanical space 22 from the opening 121 along the first direction L1.

[0075] In this way, the disassembly between the electric control box 30 and the middle partition 20 is converted into sliding between two positions, and the sliding process is controlled by the maintenance personnel only needing to apply external forces in different directions on the electric control box. There is no need to disassemble the outer shell 12, nor to expose the first mating part 31 and the second mating part 21, thereby achieving blind disassembly.

[0076] In one embodiment, a corresponding structure can be set at the target position 214 so that after the first matching part 31 reaches the target position 214, it is automatically locked and unlocked after being subjected to force, thereby fixing the electric control box 30. Other structures can also be used to fix the electric control box 30 at the target position 214.

[0077] In one embodiment, see Figure 6 to Figure 7 The outer shell 12 has a third matching portion 1231, and the electric control box 30 has a fourth matching portion 35. When the first matching portion 31 is in the initial position 213, the third matching portion 1231 is separated from the fourth matching portion 35. When the second matching portion 21 is in the target position 214, the third matching portion 1231 and the fourth matching portion 35 are fixedly connected.

[0078] At this time, the cooperation between the first matching portion 31 and the second matching portion 21 at the target position 214 is not a fixed cooperation, and the electric control box 30 needs to be fixed with the outer shell 12 to completely fix the electric control box 30. When the electric control box 30 needs to be removed, first, the top cover 11 is removed, and then the third matching portion 1231 and the fourth matching portion 35 are separated, and then the first matching portion 31 is controlled to move from the target position 214 to the initial position 213 relative to the second matching portion 21, and then the electric control box 30 is taken out. When the electric control box 30 needs to be installed, an external force is applied to the electric control box 30, so that after the first matching portion 31 moves from the initial position 213 to the target position 214, the third matching portion 1231 and the fourth matching portion 35 are fixedly connected, thereby fixing the electric control box 30.

[0079] The third matching portion 1231 and the fourth matching portion 35 may be automatically locked or separated by external force, such as elastic snap connection, or may be fixedly connected by other structures.

[0080] In one embodiment, the air conditioner outdoor unit 100 also includes a first fastener (not shown), the third matching portion 1231 and the fourth matching portion 35 are both hole-like structures, when the first matching portion 31 is in the initial position 213, the third matching portion 1231 and the fourth matching portion 35 are misaligned, when the second matching portion 21 is in the target position 214, the first fastener is detachably inserted into the third matching portion 1231 and the fourth matching portion 35.

[0081] For example, mounting holes may be provided at positions d5 and d6 on the outer shell 12, and mounting holes may be provided at corresponding positions on the electrical control box 30. The first fastener is a fastening screw, which passes through the mounting holes on the front panel 123 and the electrical control box 30 to achieve a fixed connection, or the fastening screw is removed. At this time, the electrical control box 30 can be moved relative to the outer shell 12 to achieve separation from the middle partition 20.

[0082] In one embodiment, see Figures 11 to 13 One of the first matching portion 31 and the second matching portion 21 is a positioning protrusion 31a, and the other is a positioning recess 21a. The positioning protrusion 31a is configured to be inserted into the positioning recess 21a along a third direction L3, and the third direction L3 intersects with the first direction L1. When the first matching portion 31 is in the initial position 213, the positioning protrusion 31a can be separated from the positioning recess 21a along the third direction L3 under the action of external force.

[0083] The positioning protrusion 31a can be a cylindrical protrusion, a rectangular protrusion or other structures, and the positioning groove can be a through hole structure in various shapes, such as a straight shape, an L shape, a Z shape, etc. When the positioning protrusion 31a is inserted into the positioning recess 21a along the third direction L3, the positioning protrusion 31a can slide along the opening direction of the positioning recess 21a to different positions in the positioning recess 21a.

[0084] When the electric control box 30 needs to be removed, the maintenance personnel only need to apply an external force along the third direction L3 from the side of the opening 121 to remove the positioning protrusion 31a from the positioning recess 21a, and then the electric control box 30 can be removed from the opening 121 along the first direction L1 without any hindrance. It can be understood that the electric control box 30 has a final assembly position in the housing assembly 10. When the electric control box 30 is in the final assembly position, it is limited by the third matching portion 1231 and the fourth matching portion 35 in the housing assembly 10, and the electric control box 30 cannot be directly removed from the opening 121 along the first direction L1.

[0085] In some embodiments, Fig.14The positioning recess 21a can be provided in the form of a strip-shaped through hole. In this case, the positioning recess 21a can be provided on the electric control box 30 and the middle partition plate 20. Optionally, as shown in FIG. Fig.11 , shows an embodiment in which the positioning recess 21a is provided on the middle partition 20, and the positioning protrusion 31a is provided on the electric control box 30 to prevent the opening of the electric control box 30 from affecting its sealing.

[0086] In some of the embodiments, the positioning recess 21a is a strip-shaped through hole, the longitudinal extension direction of the strip-shaped through hole is the first direction L1, and an initial position 213 and a target position 214 are respectively formed at two ends thereof. The positioning protrusion 31a can slide up and down along the first direction L1 in the strip-shaped through hole. When the positioning protrusion 31a slides to the initial position 213, an external force in a third direction L3 is applied, so that the positioning protrusion 31a is separated from the strip-shaped through hole, and the electric control box 30 is taken out.

[0087] In some other embodiments, Figure 15 to Figure 16 The second matching portion 21 is a positioning recess 21a. The second matching portion 21 includes a first sliding section 211 and a second sliding section 212 that are connected to each other. One of the first sliding section 211 and the second sliding section 212 is arranged along the first direction L1, and the other is arranged along the second direction L2. The first direction L1, the second direction L2 and the third direction L3 intersect each other. The side of the first sliding section 211 away from the second sliding section 212 forms an initial position 213, and the side of the second sliding section 212 away from the first sliding section 211 forms a target position 214.

[0088] Taking the example that the first sliding section 211 is arranged along the first direction L1 and the second sliding section 212 is arranged along the second direction L2, the complete assembly process of the electric control box is as follows: the positioning protrusion 31a is inserted into the initial position 213 in the first sliding section 211 along the third direction L3, and then slides along the first direction L1, turns, and enters the second sliding section 212, and then slides along the second direction L2 to enter the target position 214. At this time, the third matching part 1231 and the fourth matching part 35 are fixedly connected to complete the assembly.

[0089] The disassembly process is as follows: the positioning protrusion 31a, which is at the target position 214, slides along the second direction L2, and then turns and slides along the first direction L1 to enter the first sliding section 211, and then slides along the first direction L1 to enter the initial position 213. At this time, the positioning protrusion 31a is taken out from the first sliding section 211 along the third direction L3, and then the electric control box 30 is taken out from the opening 121 along the first direction L1.

[0090] The operation flow when the first sliding section 211 extends along the first direction L1 and the second sliding section 212 extends along the second direction L2 is the same and will not be repeated here. In this case, the maintenance personnel need to operate the electric control box 30 to perform two straight-line sliding and one turning to complete the assembly.

[0091] In some embodiments, Fig.17 , the second matching portion 21 is a positioning recess 21a, and the second matching portion 21 includes a third sliding section 215, a fourth sliding section 216 and a fifth sliding section 217 that are interconnected. The third sliding section 215 and the fifth sliding section 217 are arranged in the same direction, and the fourth sliding section 216 intersects and connects the two. The side of the third sliding section 215 away from the fourth sliding section 216 and the side of the fifth sliding section 217 away from the fourth sliding section 216 respectively form an initial position 213 and a target position 214. At this time, the assembly process of the electric control box 30 is as follows: the positioning protrusion 31a is inserted into the initial position 213 in the third sliding section 215 along the third direction L3, and then, slides along the extension direction of the third sliding section 215, turns, enters the fourth sliding section 216, and then, slides along the fourth direction, turns, enters the fifth sliding section 217, slides along the extension direction of the fifth sliding section 217, and arrives at the target position 214. At this time, the third matching portion 1231 and the fourth matching portion 35 are fixedly connected to complete the assembly.

[0092] In this case, the maintenance personnel need to operate the electric control box 30 to perform three straight sliding movements and two turns to complete the assembly. It can be understood that the fourth sliding section 216 and the fifth sliding section 217 can extend along the first direction L1, and the fourth sliding section 216 can extend along the second direction L2, or the fourth sliding section 216 and the fifth sliding section 217 extend along the second direction L2, and the fourth sliding section 216 extends along the first direction L1.

[0093] Furthermore, the first matching portion 31 and the second matching portion 21 can be provided in plurality, and each first matching portion 31 and a second matching portion 21 can be slidably connected to improve the connection strength between the electric control box 30 and the middle partition 20 .

[0094] In one embodiment, the chassis 127 and the top cover 11 are arranged on opposite sides of the front panel 123 in the first direction L1, the second side panel 126 and the first side panel 125 are arranged on opposite sides of the front panel 123 in the second direction L2, the rear panel and the front panel 123 are arranged on opposite sides of the panel in the third direction L3, and the middle partition plate 20 and the top cover 11, the chassis 127, the front panel 123 and the first side panel 125 are arranged to form a mechanical space 22.

[0095] When the electric control box 30 needs to be disassembled, all panels, the front panel 123, the first side panel 125, the chassis 127, the rear panel and the second side panel 126 of the outer shell 12 do not need to be disassembled. It is only necessary to remove the top cover 11 and open the side opening 121 of the outer shell 12 to conveniently and quickly take out the electric control box 30.

[0096] In one embodiment, see Fig.11The positioning recess 21a is provided on the middle partition 20, and the positioning protrusion 31a is provided on the electric control box 30. The middle partition 20 has a guide surface 24 for providing a guiding function. The guide surface 24 is respectively connected to the opening 121 and the initial position 213. The guide surface 24 is used to guide the positioning protrusion 31a to move from the opening 121 to be inserted into the initial position 213.

[0097] The initial position 213 is the initial position of the electric control box 30 in cooperation with the middle partition 20 during the installation process. When installing the electric control box 30, it is necessary to first insert the positioning protrusion 31a into the initial position 213 along the third direction L3, and this is a blind installation. If the maintenance personnel cannot observe the location of the initial position 213 from one side of the opening 121, it will also affect the assembly efficiency to a certain extent.

[0098] Therefore, in order to facilitate the insertion of the positioning protrusion 31a into the positioning recess 21a, a guide surface 24 connected to the initial position 213 and the opening 121 is provided on the middle partition 20. When the maintenance personnel operate the electric control box 30 to make the positioning protrusion 31a enter the mechanical space 22 from the opening 121, the positioning protrusion 31a slides along the guide surface 24, and then is accurately inserted into the initial position 213 from the opening 121, and then begins to slide in the positioning recess 21a to achieve assembly.

[0099] Similarly, when the electric control box 30 needs to be disassembled, the maintenance personnel operate the electric control box 30 to slide it until the positioning protrusion 31a is located at the initial position 213, so that the positioning protrusion 31a disengages from the positioning recess 21a along the third direction L3, and slides along the guide surface 24 to the opening 121 and disengages from the mechanical space 22.

[0100] In one embodiment, see Figure 18 to Figure 19 The electric control box 30 includes a cover plate 32, a control panel 33 and a bearing assembly 34. The bearing assembly 34 has a mounting position. The control panel 33 is disposed on the mounting position and is snap-connected with the bearing assembly 34. The cover plate 32 is detachably covered on the control panel 33 and is disposed between the top cover 11 and the control panel 33. The first mating portion 31 is disposed on the bearing assembly 34.

[0101] The control board 33 is a traditional PCB board structure. When the PCB in the electric control box 30 needs to be removed separately without removing the electric control box 30 as a whole, the top cover 11 is opened, the cover plate 32 is removed from the supporting assembly 34 and taken out from the opening 121, and then the control board 33 is removed from the supporting assembly 34, so that the control board 33 can be easily disassembled and repaired.

[0102] Specifically, the supporting assembly 34 includes a frame 341 and a connecting plate 342. The frame 341 is provided with a mounting position and a latch 3411 connected to the mounting position. The connecting plate 342 is connected to one side of the frame and is used for sliding cooperation with the shell assembly 10. The cover plate 32 is detachably covered on the side of the frame 341 away from the connecting plate 342. When the control board 33 is assembled on the mounting position, the latch 3411 is pressed against the side surface of the control board 33 facing the cover plate 32.

[0103] When removing the control panel 33, first remove the cover panel 32 from the frame 341, and then use the end where the latch 3411 is located as the rotation axis. The maintenance personnel apply force to rotate the control panel 33 from the installation position, and then remove the control panel 33 from under the latch 3411, so that the control panel 33 is detached from the installation position.

[0104] When installing the control board 33, the control board 33 is pressed into the installation position along the direction of the top cover 11 pointing to the chassis 127. At this time, the buckle 3411 is pressed against one side of the control board 33, or one side of the control board 33 is first pressed under the buckle 3411, and then the control board 33 is rotated to make it fit into the installation position, and then the cover plate 32 is covered and connected to the frame 341.

[0105] Generally, the frame 341 is a plastic part, which is provided with a protrusion facing the installation position side, which can deform itself when subjected to force, thereby providing an elastic snap-on part 3411. The cover plate 32 and the connecting plate 342 are sheet metal parts, which form a buckle with the frame 341 to achieve a detachable connection.

[0106] According to another aspect of the present application, an air conditioner is further provided, including an air conditioner indoor unit and an air conditioner outdoor unit 100 in any of the above embodiments, and a refrigerant communication pipeline is provided between the air conditioner indoor unit and the air conditioner outdoor unit 100.

[0107] Generally, a compressor and a condenser are installed in the outdoor unit of the air conditioner, an evaporator is installed in the indoor unit of the air conditioner, and a refrigerant connecting pipeline is provided between the compressor and the evaporator, so as to realize the heat exchange cycle between the indoor unit and the outdoor unit of the air conditioner.

[0108] It is understandable that the air conditioner indoor unit is installed indoors, and the air conditioner outdoor unit 100 is installed outdoors. After the air conditioner is assembled, if the outdoor unit needs to be repaired, the air conditioner outdoor unit 100 cannot be completely disassembled and repaired due to the setting of the refrigerant connecting pipeline between the indoor and outdoor units. Therefore, the air conditioner outdoor unit 100 is difficult to repair.

[0109] According to the solution of the present application, when the electric control box 30 in the air conditioner outdoor unit 100 is disassembled for after-sales maintenance, it is only necessary to partially or completely open the opening 121. Through the sliding cooperation of the first matching part 31 and the second matching part 21, the electric control box 30 can be easily disassembled and taken out, thereby improving the disassembly efficiency and reducing the difficulty of disassembly.

[0110] Moreover, this disassembly method enables the maintenance personnel to disassemble only one part, namely the top cover 11, at most. In some cases, the maintenance personnel can operate by climbing a ladder or opening a window indoors and extending part of the body outdoors, which is simple and convenient to operate.

[0111] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
