When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0058] With social development, air conditioners and other electrical appliances are increasingly widely used. To reduce space occupation during installation, air conditioners are often installed within the ceiling structure, meaning the indoor unit is installed inside. This installation method typically leaves only two air vents—the air outlet and the return air vent—connecting to the indoor space, while the fan and drive components are located inside the air conditioner. If the drive component malfunctions, the entire ceiling structure must be removed for repair, resulting in high maintenance costs. The air conditioner provided in this application improves upon these problems by changing the location of the drive component, thus facilitating the maintenance of the fan assembly.

[0059] This application is described below with reference to the accompanying drawings and specific embodiments:

[0060] The entire air conditioner 10 is installed within the ceiling structure 20 (e.g., Figure 1 As shown, an air outlet 22 connected to the air outlet 113 and a return air outlet 23 connected to the air inlet 114 are installed on the ceiling structure 20. The indoor air enters the receiving cavity 112 through the air inlet 114 after passing through the return air outlet 23. After heat exchange by the heat exchanger 500, it is blown into the room through the air outlet 113 and the air outlet 22.

[0061] In order to ensure that the air after heat exchange can be blown into the room as quickly as possible, the air outlet 113 and the air blower 22 are basically only a very small distance apart, so that the air outlet 113 and the air blower 22 can be basically overlapped. It can be considered that the air outlet 113 is located at the air blower 22, that is, it is located in the area of ​​the air blower 22.

[0062] The return air vent 23 and the air outlet 22 can be set on the same side of the ceiling structure 20, so that the entire ceiling structure 20 has an air outlet on only one side, which makes the entire ceiling structure 20 look cleaner and more beautiful.

[0063] It should be noted that the air conditioner 10 includes two parts: an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed indoors. The fact that the air conditioner 10 is installed in the ceiling means that the indoor unit of the air conditioner 10 is installed in the ceiling, not that both the indoor and outdoor units are installed in the ceiling. This part is common knowledge in the field and will not be elaborated further.

[0064] Please see Figure 2 and Figure 3 In this embodiment, the air conditioner 10 includes: a housing 100, a heat exchanger 500, a fan assembly 300, and a drive assembly 400. The housing 100 has a receiving cavity 112 and an air outlet 113 communicating with the receiving cavity 112. The heat exchanger 500 and the fan assembly 300 are both installed in the receiving cavity 112. The fan assembly 300 includes a fan wheel 310 and a volute assembly 390. The volute assembly 390 has an air cavity 394, and the fan wheel 310 is installed in the air cavity 394. The drive assembly 400 includes a drive member 410, a motor base 430, and a motor cover 420. The drive member 410 is connected to the fan wheel 310 in a transmission manner. The motor cover 420 is detachably connected to the motor base 430 to form a fixed cavity. The drive member 410 is installed in the fixed cavity, and the motor cover 420 is located at the air outlet 113.

[0065] The housing 100 is the main body of the entire air conditioner 10, providing a mounting base for other components of the air conditioner 10. These other components are installed within the receiving cavity 112 of the housing 100. The housing 100 protects these components, reducing the risk of external impurities entering the receiving cavity 112 and protecting the internal structure. Furthermore, placing all other components within the housing 100 allows the air conditioner 10 to form a unified whole, facilitating its installation and transportation.

[0066] The housing 100 is roughly rectangular. For ease of description, it is defined in three directions: height (Z), width (X), and depth (Y). Height (Z) is the vertical direction of the air conditioner 10 in its installed state; width (X) is the direction of the longest side of the housing 100; and depth (Y) is the direction perpendicular to both height (Z) and width (X). For simplicity, the two ends along height (Z) are defined as "up" and "down," with one end of the drip tray designated as "down" and the other as "up." Along width (X), the two ends are designated as follows: one end of the electronic control component is designated as "left," and the other as "right." Along depth (Y), the two ends are designated as follows: one end of the air outlet 113 is designated as "front," and the other as "rear."

[0067] The housing 100 also has an air inlet 114, which is located on the side opposite to the air outlet 113. The air inlet 114 and the air outlet 113 are spaced apart along the depth direction Y of the housing 100. For ease of description, the orientation of the air outlet 113 is defined as "front," and the orientation of the air inlet 114 as "rear." Along the height direction Z of the housing 100, "up" in the vertical direction is "up," and "down" in the vertical direction is "down." Along the width direction X, the side where the electronic control components are located is designated as "right," and the other side as "left."

[0068] The motor cover 420 is located at the air outlet 113, meaning the entire fan assembly 300 is positioned closer to the air outlet 113. Since the fan assembly 300 is positioned closer to the air outlet 113, if the fan assembly 300 needs to be replaced or repaired, the entire fan assembly 300 can be inspected directly from the air outlet 113. The operation is simple and convenient, and there is no need to set up a separate inspection port.

[0069] The motor cover 420 is detachably connected to the motor base 430, and the motor cover 420 is located at the air outlet 113. If it is necessary to repair or replace the drive component 410, the motor cover 420 can be removed from the motor base 430, so that the drive component 410 can be exposed from the air outlet 113. The drive component 410 can be inspected directly through the air outlet 113 without damaging the original ceiling structure 20. This reduces the difficulty of inspecting the fan assembly 300 and facilitates the replacement and repair of the fan assembly 300.

[0070] The motor cover 420 and the motor base 430 are detachably connected to form a fixed cavity for mounting the drive component 410. The drive component 410 is installed in the fixed cavity, and the motor base 430 is fixedly mounted on the housing 100. The motor cover 420 and the motor base 430 are detachably connected. The motor cover 420 can be detachably connected to both the housing 100 and the motor base 430, or it can be detachably connected only to the motor base 430 without being connected to the housing 100. When it is necessary to inspect the drive component 410, the connection between the motor cover 420 and the motor base 430 can be released, allowing the motor cover 420 to be removed from the receiving cavity 112, while the motor base 430 remains fixed in the receiving cavity 112. After the motor cover 420 is removed, the drive component 410 can be exposed from the air outlet 113, allowing for direct inspection and maintenance of the drive component 410 from the air outlet 113.

[0071] Specifically, since the entire air conditioner 10 is installed within the ceiling structure 20, which has an air outlet 22 and a return air outlet 23, the air outlet 22 is connected to the air outlet 113, and the return air outlet 23 is connected to the air inlet 114. Both the air outlet 22 and the return air outlet 23 are equipped with grilles. When it is necessary to inspect the drive component 410, the grille at the air outlet 22 is first removed, exposing the air outlet 113 of the entire air conditioner 10. Since the motor cover 420 is located at the air outlet 113, the connection between the motor cover 420 and the motor base 430 is released, allowing the motor cover 420 to be removed from the receiving cavity 112, while the motor base 430 remains fixed within the receiving cavity 112. After the motor cover 420 is removed, the drive component 410 can be exposed from the air outlet 113, allowing for direct inspection of the drive component 410 from the air outlet 113.

[0072] Regarding the detachable connection method between the motor base 430 and the motor cover 420, one of the motor base 430 and the motor cover 420 may have a limiting part 429, and the other may have a limiting groove 436, with the limiting part 429 disposed within the limiting groove 436. The cooperation between the limiting part 429 and the limiting groove 436 allows the motor base 430 and the motor cover 420 to be fixed together (e.g., ...). Figure 6 (as shown in the image).

[0073] The limiting groove 436 is provided along the depth direction Y of the housing 100, so that the limiting part 429 can be guided during the sliding of the limiting part 429 along the limiting groove 436, which facilitates the installation and removal of the motor cover 420.

[0074] Please see Figure 4 In some embodiments, along the depth direction Y of the housing 100, the heat exchanger 500 and the fan assembly 300 are spaced apart. The fan assembly 300 is located near the air outlet 113. The volute assembly 390 has a disassembly port 392, and the motor cover 420 is installed in the disassembly port 392.

[0075] The heat exchanger 500 and the fan assembly 300 are arranged sequentially along the depth direction Y of the housing 100, with the fan assembly 300 positioned closer to the air outlet 113 and the heat exchanger positioned closer to the air inlet 114. Specifically, of the two components, the heat exchanger 500 is positioned closer to the air inlet 114, and the fan assembly 300 is positioned closer to the air outlet 113. External air enters the housing 112, first exchanges heat with the heat exchanger 500, then passes through the fan assembly 300 and is blown out from the air outlet 113. The heat exchanger 500 is located on the suction side of the fan assembly 300; this arrangement can be considered as a suction-type air conditioner 10.

[0076] In the heat exchanger 500 and the fan assembly 300, the fan assembly 300 is positioned closer to the air outlet 113. This allows the air entering the housing 112 from the air inlet 114 to first undergo heat exchange in the heat exchanger 500 before passing through the fan assembly 300 and being blown out of the air outlet 113. Because the air blown out of the fan assembly 300 does not pass through the heat exchanger 500, the static pressure resistance of the entire air conditioner 10 is improved. It also reduces the air resistance of the air blown out of the air outlet 113, resulting in a more uniform temperature of the air blown out of the air outlet 113.

[0077] Since the drive component 410 is mainly used to drive the fan wheel 310 of the fan assembly 300 to rotate, the position between the drive component 410 and the fan wheel 310 is relatively close. Installing the motor cover 420 on the disassembly port 392 of the volute assembly 390 can make the overall structure of the air conditioner 10 more compact, and can minimize the space occupied by the air conditioner 10, so that the air conditioner 10 can be miniaturized and made lighter.

[0078] In some embodiments, the impeller 310 includes a plurality of impellers, and the volute assembly 390 includes a volute body assembly 330 and a volute cover assembly 320. The volute cover assembly 320 is detachably connected to the volute body assembly 330 to form a plurality of air chambers 394, and the plurality of impellers 310 are respectively installed in the plurality of air chambers 394.

[0079] The volute cover assembly 320 is located at the air outlet 113, and the disassembly port 392 is provided at least in the volute cover assembly 320.

[0080] The volute cover assembly 320 is located at the air outlet 113, meaning the entire fan assembly 300 is positioned closer to the air outlet 113. Since the fan assembly 300 is positioned closer to the air outlet 113, if the fan assembly 300 needs to be replaced or repaired, the entire fan assembly 300 can be inspected directly from the air outlet 113. The operation is simple and convenient, and there is no need to set up a separate inspection port.

[0081] The volute cover assembly 320 is detachably connected to the volute body assembly 330, and the volute cover assembly 320 is located at the air outlet 113. If it is necessary to repair or replace the impeller 310, the volute cover assembly 320 can be removed from the volute body assembly 330, so that the impeller 310 can be exposed from the air outlet 113. The impeller 310 can be directly inspected through the air outlet 113 without damaging the original ceiling structure 20. This reduces the difficulty of inspecting the fan assembly 300 and facilitates the replacement and repair of the fan assembly 300.

[0082] The volute cover assembly 320 is detachably connected to the volute body assembly 330 to form an air cavity 394 for mounting the impeller 310. The impeller 310 is installed inside the air cavity 394. The volute body assembly 330 is fixedly mounted on the housing 100. The volute cover assembly 320 is detachably connected to the volute body assembly 330. The volute cover assembly 320 can be detachably connected to both the housing 100 and the volute body assembly 330, or it can be detachably connected only to the volute body assembly 330 without being connected to the housing 100. When it is necessary to inspect and maintain the fan assembly 300, the connection between the volute cover assembly 320 and the volute body assembly 330 can be released, allowing the volute cover assembly 320 to be removed from the receiving cavity 112, while the volute body assembly 330 remains fixed inside the receiving cavity 112. After the volute cover assembly 320 is disassembled, the impeller 310 can be exposed from the air outlet 113, and the impeller 310 can be inspected directly from the air outlet 113.

[0083] Specifically, since the entire air conditioner 10 is installed within the ceiling structure 20, which has an air outlet 22 and a return air outlet 23, the air outlet 22 is connected to the air outlet 113, and the return air outlet 23 is connected to the air inlet 114. Both the air outlet 22 and the return air outlet 23 are equipped with grilles. When the fan assembly 300 needs to be inspected, the grille at the air outlet 22 is first removed, exposing the air outlet 113 of the entire air conditioner 10. Since the volute cover assembly 320 is located at the air outlet 113, the connection between the volute cover assembly 320 and the volute body assembly 330 is released, allowing the volute cover assembly 320 to be removed from the receiving cavity 112, while the volute body assembly 330 remains fixed within the receiving cavity 112. After the volute cover assembly 320 is disassembled, the impeller 310 can be exposed from the air outlet 113, and the impeller 310 can be inspected directly from the air outlet 113.

[0084] Since the volute cover assembly 320 is located at the air outlet 113, the disassembly port can be located on the volute cover assembly 320, that is, the motor cover 420 is located at the air outlet 113.

[0085] The volute cover assembly 320 includes multiple volute covers 321, and the volute body assembly 330 includes multiple volute bodies 331. A volute cover 321 and a volute body 331 are connected to form a wind cavity 394 (a complete volute).

[0086] Please see Figure 5 In some embodiments, the volute cover assembly 320 includes a first cover section 320a and a second cover section 320b, both of which are connected to the volute body assembly 330. The first cover section 320a, the second cover section 320b and the volute body assembly 330 form a disassembly / removal port 392.

[0087] The first cover section 320a and the second cover section 320b form a disassembly port 392 with the volute body assembly 330, making the first cover section 320a and the second cover section 320b a split structure, which can reduce the molding difficulty of the disassembly port 392 and reduce manufacturing costs.

[0088] In addition, the first cover section 320a and the second cover section 320b are separate structures. The first cover section 320a and the second cover section 320b are separate structures. When only the wind turbine 310 corresponding to the first cover section 320a needs to be inspected, only the first cover section 320a can be disassembled. When only the wind turbine 310 corresponding to the second cover section 320b needs to be inspected, only the second cover section 320b can be disassembled, which makes the inspection of the wind turbine 310 more precise.

[0089] In some embodiments, along the width direction X of the housing 100, the motor cover 420 is disposed between the first cover section 320a and the second cover section 320b.

[0090] Since there are multiple impellers 310, the drive unit 410 needs to drive multiple impellers 310 simultaneously. Therefore, the drive unit 410 can be placed in the middle of the multiple impellers 310, so that the drive unit 410 can drive the impellers 310 on both sides. Since the motor cover 420 covers the drive unit 410, the first cover section 320a and the second cover section 320b respectively cover different impellers 310. Since the motor cover 420 can be placed between the first cover section 320a and the second cover section 320b, the drive unit 410 can drive the left and right impellers 310, reducing the length of the drive shaft.

[0091] In some embodiments, the volute cover assembly 320 and the motor cover 420 are arranged side by side along the width direction X of the housing 100. This allows the volute cover assembly 320 and the motor cover 420 to be both located at the air outlet 113, and both the volute cover assembly 320 and the motor cover 420 assembly can be disassembled individually.

[0092] If the impeller 310 needs to be inspected, only the first cover section 320a or the second cover section 320b needs to be removed. If the drive unit 410 needs to be inspected, only the motor cover 420 needs to be removed. The inspection functions of the impeller 310 and the drive unit 410 are independent of each other, making the operation more convenient.

[0093] The above describes the installation location of the motor cover 420. The following will describe how to assemble and disassemble the motor cover 420 with the volute cover assembly 320 and the volute body assembly 330.

[0094] Please see Figure 6 In some embodiments, the motor cover 420 is detachably connected to the volute cover assembly 320 and the volute body assembly 330.

[0095] Since the motor cover 420 is roughly rectangular, the disassembly opening is also roughly rectangular. The motor cover 420 is detachably connected to the volute cover assembly 320 and the volute body assembly 330, respectively. The motor cover 420 can be fixed from different positions, thereby improving the fixing effect of the motor cover 420.

[0096] Specifically, the volute cover assembly 320 is provided with a first overlapping portion 325, and the motor cover 420 has a second overlapping portion 426. The first overlapping portion 325 is disposed on the second overlapping portion 426 and is detachably connected to the second overlapping portion 426.

[0097] The first overlapping portion 325 can protrude into the disassembly port 392, and the second overlapping portion 426 overlaps the first overlapping portion 325 and is detachably connected. The first overlapping portion 325 and the second overlapping portion 426 can be fixedly connected by screws.

[0098] The volute body assembly 330 is provided with a third overlapping portion 332, and the motor cover 420 is provided with a fourth overlapping portion 427. The third overlapping portion 332 overlaps the fourth overlapping portion 427 and is detachably connected to the fourth overlapping portion 427. Similarly, the overlap between the third overlapping portion 332 and the fourth overlapping portion 427 can also be fixed by using screws.

[0099] Multiple first overlapping portions 325 and second overlapping portions 426 can be provided, respectively located at different positions on the volute cover assembly 320 and the motor cover 420. Multiple third overlapping portions 332 and fourth overlapping portions 427 can also be provided, respectively located at different positions on the volute body assembly 330 and the motor cover 420.

[0100] The first overlapping portion 325, the second overlapping portion 426, the third overlapping portion 332, and the fourth overlapping portion 427 are screwed from the front of the housing 100. After the air outlet grille 21 is removed, the first overlapping portion 325, the second overlapping portion 426, the third overlapping portion 332, and the fourth overlapping portion 427 can all be exposed from the air outlet 113. The operator can directly remove the screws to separate the motor cover 420 and the motor base 430, so that the drive component 410 can be exposed from the air outlet 113, which facilitates the maintenance of the drive component 410.

[0101] In some embodiments, the motor mount 430 and the volute body assembly 330 are an integral structure. During assembly, the motor mount 430 and the volute body assembly 330 can be directly assembled onto the housing 100, and then the impeller 310 and the drive component 410 can be assembled separately. There is no need to assemble the motor mount 430 and the volute body assembly 330 separately, which facilitates the assembly of the entire air conditioner 10, reduces assembly steps, and lowers the assembly difficulty.

[0102] Please see Figure 7In some embodiments, the volute body assembly 330 includes a first volute component 340 and a second volute component 350, the first volute component 340 and the second volute component 350 are connected, and the motor mount 430 includes a first mount body 434 and a second mount body 435, the first volute component 340 and the second mount body 435 are an integral structure, and the second volute component 350 and the first mount body 434 are an integral structure.

[0103] Among them, the impeller 310 is a centrifugal impeller, and the drive motor 412 of the drive component 410 is also roughly circular. To facilitate the assembly of the centrifugal impeller and the motor, the volute body assembly 330 can be divided into two sections, and similarly, the motor base 430 can also be divided into two sections. During assembly, the second volute component 350 and the first base 434 can be assembled as a whole on the top plate 122 of the housing 100 first, then the impeller 310 and the drive component 410 are assembled separately, and then the volute cover assembly 320, the first volute component 340 and the second base 435 as a whole, and the motor cover 420 are assembled.

[0104] The air conditioner 10 is mostly assembled upside down. First, the top plate 122 of the casing 100 is placed on the work surface. The upper volute and motor mount 430 are then assembled onto the top plate 122. The fan wheel 310 is placed on the upper volute, and then the middle and lower volutes are assembled. Similarly, after assembling the motor mount 430 onto the top plate 122, the drive motor 412 of the drive unit 410 is assembled onto the motor mount 430. Finally, the motor cover 420 and the middle volute are assembled as a whole. To facilitate the installation and maintenance of the drive motor 412, part of the motor cover 420 is located below the drive motor 412. When the motor cover 420 is removed along with the volute cover 321, the drive motor 412 may fall off the motor mount 430 under its own weight. Since the drive motor 412 has a certain weight, if it falls onto the base plate 124, it may damage the drive motor 412 or deform the base plate 124.

[0105] Please see Figure 8 In order to solve the above problems, this application provides an embodiment of an implementation method, one of which is to change the structure of the motor cover 420 and the motor base 430 to support the drive component 410.

[0106] The motor cover 420 includes a first cover 424 and a second cover 425, with the second cover 425 fixedly connected to the first cover 424.

[0107] The motor cover 420 is composed of a first cover 424 and a second cover 425. When assembling the drive component 410, the first cover 424 and the second cover 425 are separate structures. When assembling the drive component 410, the first cover 424 and the motor base 430 can be assembled together first, and then the second cover 425 can be assembled onto the first cover 424. The second cover 425 and the first cover 424 are fixedly connected. The fixing method can be as follows: the first cover 424 and the second cover 425 can be positioned by a positioning structure and then fixed by a fixing structure.

[0108] Specifically, in the first cover 424 and the second cover 425, one can be provided with a buckle, and the other with a slot. The buckle engages with the slot. The second cover 425 is positioned on the first cover 424 through the cooperation of the buckle and the slot. The first cover 424 and the second cover 425 are then secured by screws. The slot can be a through slot or a blind slot.

[0109] Wherein, the edge of the first seat 434 away from the first cover 424 is connected to the center of the drive member 410 to form a first line, and the edge of the first cover 424 away from the first seat 434 is connected to the center of the drive member 410 to form a second line, and the angle between the first line and the second line is less than or equal to 180 degrees.

[0110] The edge of the first cover 424 away from the second cover 425 is connected to the center of the drive member 410 to form a third line, and the edge of the second cover 425 away from the first cover 424 is connected to the center of the drive member 410 to form a fourth line. The angle between the third line and the fourth line is greater than or equal to 180 degrees.

[0111] When assembling the drive unit 410, the first base 434 is first fixed on the top plate 122, and the first cover 424 is fixed by the middle volute. Since the central angle formed by the first base 434 and the first cover 424 is less than or equal to 180 degrees, the drive motor 412 can be placed in the structure formed by the first cover 424 and the first base 434. Then, the second cover 425 is assembled on the first cover 424, and the second base 435 is assembled on the first base 434 to fix the drive motor 412.

[0112] Furthermore, since the central angle formed by the first cover 424 and the second cover 425 is greater than or equal to 180 degrees, the drive motor 412 can be exposed after the entire first cover 424 and the second cover 425 are disassembled, so that the drive motor 412 can be removed from the air outlet 113. This arrangement facilitates the maintenance of the drive motor 412.

[0113] The second base 435 is located directly below the drive motor 412, which can support the drive motor 412 and prevent the drive motor 412 from falling after the entire motor cover 420 is removed.

[0114] Please see Figure 9 In some embodiments, the drive unit 410 includes a drive motor 412, a coupling 413 and a transmission shaft 414. The drive motor 412 is disposed between two adjacent impellers 310. The drive motor 412 is connected to the transmission shaft 414 through the coupling 413. The transmission shaft 414 connects multiple impellers 310.

[0115] Since the motor cover 420 is located at the air outlet 113 and can be directly removed from the motor base 430, the drive motor 412 can be directly inspected. Because both sides of the drive motor 412 are connected to multiple impellers 310, couplings 413 can be installed on both sides of the drive motor 412 to allow for disassembly and reassembly. When the drive motor 412 needs to be inspected, the drive motor 412 and the couplings 413 are separated, allowing the drive motor 412 to be individually removed from the air outlet 113.

[0116] In summary, the disassembly and assembly process of the air conditioner 10 provided in this application embodiment is as follows: After the air outlet grille 21 is removed, the first overlapping part 325, the second overlapping part 426, the third overlapping part 332, and the fourth overlapping part 427 can all be exposed from the air outlet 113. The operator can directly remove the screws to separate the motor cover 420 and the motor base 430, so that the drive component 410 can be exposed from the air outlet 113. Then, the drive motor 412 and the coupling 413 can be separated, and the drive motor 412 can be removed from the disassembly port 392 and the air outlet 113. After the drive motor 412 has been repaired, first place the drive motor 412 in the fixed cavity, connect the drive motor 412 and the coupling 413, place the motor cover 420 in the disassembly port, and push the motor cover 420 inward along the depth direction Y of the housing 100 so that the first overlapping part 325 overlaps with the second overlapping part 426, and the third overlapping part 332 overlaps with the fourth overlapping part 427. After fixing the first overlapping part 325, the second overlapping part 426, the third overlapping part 332, and the fourth overlapping part 427 with screws, the motor cover 420 is installed.

[0117] In some embodiments, the volute cover assembly 320 and the volute body assembly 330 can also be detachably connected, thereby facilitating the maintenance of the impeller 310. The specific connection method is as follows:

[0118] Please see Figure 10 and Figure 11In some embodiments, the first volute 340 includes a plurality of lower volutes 341, and the second volute 350 includes a plurality of upper volutes 351. The lower volutes 341 are connected to the upper volutes 351. Each lower volute 341 and each upper volute 351 is detachably connected to a volute cover 321 to form a volute module 396. That is, a lower volute 341, an upper volute 351, a volute cover 321 and a wind turbine 310 can form a wind turbine module.

[0119] The lower volute 341 and the upper volute 351 are both fixedly installed in the receiving cavity 112 and are fixedly connected to the housing 100. The housing 100 may include a top plate 122 and a bottom plate 124 disposed opposite to the top plate 122. The lower volute 341 is disposed below the upper volute 351 and is fixedly connected to the bottom plate 124. The upper volute 351 is connected to the lower volute 341 and to the top plate 122.

[0120] During assembly, an inverted method can be used. First, the upper volute 351 is fixed to the top plate 122, the impeller 310 is placed inside the upper volute 351, the lower volute 341 is then snapped onto the upper volute 351, and finally the volute cover 321 is assembled. This facilitates the assembly of the impeller 310.

[0121] In other words, in this embodiment, the volute of the wind turbine assembly 300 is a three-section structure, consisting of a lower volute 341, an upper volute 351, and a volute cover 321. This design facilitates the assembly and maintenance of the entire wind turbine assembly 300. Alternatively, the volute can also be a two-section structure, where the volute body 331 is a single unit. Furthermore, the volute can also be a four-section structure or other forms; specific details are not limited.

[0122] As for the connection method between the lower volute 341 and the upper volute 351, they can be snap-fitted or fixedly connected by screws or other fasteners. In some embodiments, the lower volute 341 and the upper volute 351 are snap-fitted together. The following will describe in detail how the volute 341 and the upper volute 351 are snap-fitted together.

[0123] Please see Figure 12 , Figure 13 and Figure 14 In some embodiments, the lower volute 341 is provided with a first retaining member 342, and the upper volute 351 is provided with a second retaining member 352, with the first retaining member 342 and the second retaining member 352 engaging.

[0124] Specifically, the second retaining member 352 includes a retaining portion 353, and the first retaining member 342 is provided with a retaining hole 343, the retaining portion 353 being able to engage with the retaining hole 343. The retaining portion 353 includes a connecting section 353a and a retaining section 353b protruding from the connecting section 353a, the connecting section 353a passing through the retaining hole 343, and the retaining section 353b abutting against the retaining hole 343.

[0125] The first retaining member 342 is also provided with a guide portion 347. During the assembly of the lower volute 341 and the upper volute 351, the retaining portion 353 can slide relative to the guide portion 347, and the guide portion 347 can abut against the retaining portion 353, so that the retaining portion 353 can be inserted into the retaining hole 343.

[0126] In addition, of the two retaining parts 342 and 352, one is provided with a slot 354 and the other is provided with a plug-in part 344. During assembly, the plug-in part 344 is inserted into the slot 354. The cooperation between the two can not only realize the assembly of the lower volute 341 and the upper volute 351, but also seal the gap (air cavity 394) between the lower volute 341 and the upper volute 351, thereby reducing the possibility of air leakage between the lower volute 341 and the upper volute 351.

[0127] Please see Figure 15 In some embodiments, a first guide surface 322 is provided on the volute cover 321, and a second guide surface 356 is provided on the upper volute 351. The shapes of the first guide surface 322 and the second guide surface 356 are adapted to each other, so that the first guide surface 322 can slide along the second guide surface 356 to assemble the volute cover 321 onto the upper volute 351.

[0128] The matching shape of the first guide surface 322 and the second guide surface 356 means that if the first guide surface 322 is convex, then the second guide surface 356 is concave. This concave-convex structure allows for the positioning of the volute cover 321. Specifically, if the first guide surface 322 is a concave arc surface, then the second guide surface 356 is a convex arc surface. If the first guide surface 322 is an L-shaped concave surface, then the second guide surface 356 is an L-shaped convex surface.

[0129] The first guide surface 322 and the second guide surface 356 work together to provide guidance. At the same time, the first guide surface 322 is inserted into the second guide surface 356, which can also provide a certain sealing effect and reduce the risk of air leakage between the volute body 331 and the volute cover 321.

[0130] The second guide surface 356 is arranged along the air outlet direction of the entire air conditioner 10, that is, when it is necessary to remove the volute cover 321, the entire volute cover 321 can be pulled out along the air outlet direction. Since the air inlet 114 and the air outlet 113 are arranged in the depth direction Y of the housing 100, the air outlet direction is consistent with the depth direction Y of the housing 100.

[0131] In some embodiments, at least one of the second guide surface 356 and the first guide surface 322 is inclined along the depth direction Y of the housing 100. The inclination of at least one of the second guide surface 356 and the first guide surface 322 along the depth direction Y of the housing 100 can be either only the second guide surface 356, only the first guide surface 322, or both the first guide surface 322 and the second guide surface 356 are arranged along the depth direction Y of the housing 100.

[0132] At least one of the second guide surface 356 and the first guide surface 322 is inclined along the depth direction Y of the housing 100. During the process of disassembling and assembling the volute cover 321, it can play a positioning role for the volute cover 321, so that the volute cover 321 can slide to the set position as much as possible.

[0133] The first guide surface 322 and the second guide surface 356 are two in total, respectively set on both sides along the axial direction of the impeller 310. They cooperate with the volute body 331 on both sides when assembling or disassembling the volute cover 321, which can improve the stability of the assembly of the volute cover 321 and the volute body 331.

[0134] Please see Figure 11 and Figure 15 In some embodiments, the lower volute 341 is provided with a positioning part 345 and is located near the air outlet 113. The volute cover 321 is provided with a positioning cover 323, which covers the positioning part 345. The first guide surface 322 and the second guide surface 356, and the positioning cover 323 covering the positioning part 345 can seal the connection between the lower volute 341 and the volute cover 321, thereby reducing air leakage.

[0135] In some embodiments, there are multiple impellers 310 and multiple volute covers 321, with the multiple volute covers 321 integrally formed to form a first cover section 320a or a second cover section 320b. The impellers 310 are centrifugal impellers. Since the housing 100 has a relatively long length in the width direction X, multiple impellers 310 can be arranged within the receiving cavity 112. The multiple impellers 310 arranged along the width direction X of the housing 100 can increase the airflow entering the receiving cavity 112 and enhance the overall heat exchange effect of the air conditioner 10.
