[0050] This application is described below with reference to the accompanying drawings and specific embodiments:

[0051] 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 provided 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.

[0052] 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.

[0053] 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.

[0054] 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 structure 20 means that the indoor unit of the air conditioner 10 is installed in the ceiling structure 20, not that both the indoor and outdoor units are installed in the ceiling structure 20. This part is common knowledge in the field and will not be elaborated further.

[0055] This application provides an air conditioner 10. The air conditioner 10 provided by this application can, as far as possible, prevent the drive component 410 from detaching from the motor mount 430 during the maintenance of the drive component 410, thereby reducing the possibility of damage to the drive component 410 and also preventing the base plate 124 from deforming due to the drive component 410 falling.

[0056] Please see Figure 2 , Figure 3 and Figure 4 This application provides an air conditioner 10. The air conditioner 10 provided in this application embodiment can directly inspect and repair the impeller 310 through the air outlet 113 without damaging the original ceiling structure 20, which can reduce the inspection and repair difficulty of the fan assembly 300 and facilitate the replacement and maintenance of the fan assembly 300.

[0057] In this embodiment of the application, the air conditioner 10 includes: a housing 100, a fan assembly 300, a drive assembly 400, and a support member 810. The housing 100 has a receiving cavity 112 and an air outlet 113 communicating with the receiving cavity 112. The fan assembly 300 includes a volute assembly 390 and a fan wheel 310 disposed in the volute assembly 390.

[0058] The drive assembly 400 includes a drive member 410, a motor base 430, and a motor cover 420, all of which are disposed within the receiving cavity 112. The drive member 410 is connected to the impeller 310 in a transmission manner. The motor base 430 is detachably connected to the motor cover 420 for fixing the drive member 410. The support member 810 is disposed within the receiving cavity 112 and can support the drive member 410.

[0059] 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.

[0060] The housing 100 is roughly rectangular. For ease of description, the housing 100 is defined by three directions: height Z, width X, and depth Y. The height Z is the vertical direction of the air conditioner 10 in the installed state, the width X is the direction of the longest side of the housing 100, and the depth Y is the direction perpendicular to both the height Z and width X.

[0061] 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 electronic control component 700 is located at one end of the housing 100. The side where the electronic control component 700 is located is defined as "right", and the other side as "left". The electronic control component 700 is electrically connected to the drive component 400, providing power to the drive component 400 and controlling the start and stop of the drive component 400.

[0062] 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 500 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 receiving cavity 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.

[0063] Along the depth direction Y of the casing 100, the heat exchanger 500 and the fan assembly 300 are spaced apart, with the fan assembly 300 positioned close to the air outlet 113. This ensures that the air entering the housing 112 from the air inlet 114 first undergoes heat exchange through the heat exchanger 500 before passing through the fan assembly 300 and being blown out of the air outlet 113. Since 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.

[0064] The air conditioner 10 is mostly assembled upside down. First, the top plate 122 of the casing 100 is placed on the work surface. 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 320 are assembled as a whole. This facilitates the installation and maintenance of the drive motor 412. The motor cover 420 is partially 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 and may also deform the base plate 124.

[0065] In some other embodiments, the motor base 430 and the motor cover 420 are integrated. During assembly, the motor base 430 is assembled first, so that the motor cover 420 is positioned below the drive component 410. To prevent the entire drive component 410 from sagging after the motor cover 420 is disassembled, a support member 810 can be provided in the receiving cavity 112 to support the drive component 410. After the motor cover 420 is disassembled, the support member 810 can provide temporary support for the drive component 410, which can minimize the possibility of the drive component 410 detaching from the motor base 430, thereby reducing the possibility of damage to the drive component 410 and minimizing the possibility of the base plate 124 deforming due to the drive component 410 sagging.

[0066] It should be noted that when the air conditioner 10 is working normally, the support 810 does not support the drive 410. In other words, when the air conditioner 10 is working normally, there is no installation relationship or connection relationship between the support 810 and the drive 410.

[0067] In some embodiments, the support member 810 is mounted on the housing 100. Since the support member 810 provides temporary support for the drive member 410, the support member 810 can be mounted on the base plate 124 of the housing 100, so that the position of the support member 810 within the housing 100 is fixed and there will be no shaking or displacement during installation or transportation.

[0068] The support component 810 can be an integral structure with the base plate 124 or a separate structure; the specific method is not limited.

[0069] In some embodiments, the support member 810 is disposed below the drive member 410 and spaced apart from it. Since the support member 810 mainly serves to temporarily support the drive member 410 after the motor cover 420 is removed, it can be disposed below the drive member 410. Because the drive member 410 needs to drive the impeller 310 to rotate, and the drive member 410 needs to rotate during operation, the support member 810 can be spaced apart from the drive member 410 to avoid interference.

[0070] The support member 810 can also be integrally formed with the lower volute 340, that is, the support member 810 and the first shell section 341 are integrally formed. During assembly, the support member 810 and the lower volute 340 can be assembled as a whole. This assembly method is simple to operate and can reduce assembly steps.

[0071] The distance between the support member 810 and the drive member 410 is not specifically limited, as long as it can support the drive member 410 after the motor cover 420 is removed.

[0072] In some embodiments, there are multiple wind turbines 310, and the driving member 410 includes a driving motor 412 and a transmission shaft 413. The driving motor 412 is connected to the transmission shaft 413, and the driving motor 412 or the transmission shaft 413 is connected to the wind turbine 310. The driving motor 412 is disposed in the motor cavity. The support member 810 can support the transmission shaft 413.

[0073] The drive motor 412 is installed in the motor cavity formed by the motor base 430 and the motor cover 420. The volume of the drive motor 412 is larger than that of the transmission shaft 413. The distance between the drive motor 412 and the base plate 124 is relatively close. If a support member 810 is set in the space between the drive motor 412 and the base plate 124, the height of the support member 810 will be relatively small, resulting in lower strength of the support member 810. Furthermore, due to the small space between the drive motor 412 and the base plate 124, the support member 810 will interfere with the drive motor 412.

[0074] The support member 810 can be placed below the drive shaft 413 to support the drive motor 412. This can minimize interference between the support member 810 and the drive motor 412, and also minimize interference between the support member 810 and the motor cover 420, thus avoiding the problem of the motor cover 420 not being able to be disassembled.

[0075] Of course, although the support member 810 is located below the drive shaft 413, it is also located close to the drive motor 412, so as to support the drive motor 412.

[0076] Specifically, since there are multiple impellers 310, they are arranged sequentially at intervals along the width direction X of the housing 100, meaning there is a gap between adjacent impellers 310. The drive motor 412 and the support member 810 are located within the same gap. In other words, the support member 810 is considered to be located close to the drive motor 412 when the drive motor 412 and the support member 810 are located within the same gap.

[0077] In some embodiments, the support member 810 has a support surface 812, the shape of which is adapted to the shape of the drive shaft 413.

[0078] The shape of the support surface 812 being compatible with the shape of the drive shaft 413 means that if the drive shaft 413 is approximately cylindrical, then the shape of the support surface 812 is also arc-shaped. The support surface 812 is located on top of the support member 810, and its shape is compatible with the shape of the drive shaft 413. This ensures that when the drive shaft 413 is positioned on the support surface 812, the support surface 812 can cover the drive shaft 413, improving the fixation effect on the drive shaft 413.

[0079] In some embodiments, the drive shaft 413 includes a first shaft segment 413a and a second shaft segment 413b, which are located on both sides of the drive motor 412. The end of the first shaft segment 413a away from the drive motor 412 is mounted on the bearing seat 820, and the support member 810 can support the second shaft segment 413b.

[0080] Since there are multiple wind turbines 310, the drive motor 412 needs to drive multiple wind turbines 310 through the transmission shaft 413. Since the drive motor 412 is located between two adjacent wind turbines 310, the drive motor 412 can be connected to the wind turbines 310 on both the left and right sides. Since there are multiple wind turbines 310, the wind turbines 310 that are farther away from the drive motor 412 are connected through the transmission shaft 413, which makes the transmission shaft 413 potentially long. To facilitate the fixing of the transmission shaft 413, a bearing seat 820 can be provided to fix the transmission shaft 413.

[0081] For ease of explanation, we will use an example with three wind turbines 310. From left to right, they are the first wind turbine 310, the second wind turbine 310, and the third wind turbine 310. The drive motor 412 and the support member 810 are located between the second and third wind turbines 310. The first shaft segment 413a is connected to the first and second wind turbines 310, and the second shaft segment 413b is connected to the third wind turbine 310. Since the first shaft segment 413a needs to connect two wind turbines 310, the length of the first shaft segment 413a is greater than the length of the second shaft segment 413b. Fixing the end of the first shaft segment 413a away from the drive motor 412 to the bearing seat 820 can improve the stability of the first shaft segment 413a.

[0082] Regarding the installation position of the bearing housing 820, the bearing housing 820 can be installed on the side plate 123 of the housing 100, or it can be installed on the volute assembly 390. The volute assembly 390 includes an upper volute 350, a middle volute 320, and a lower volute 340. The upper volute 350 has a first mounting section 831, and the middle volute 320 has a second mounting section 832. The first mounting section 831 and the second mounting section 832 form a mounting frame 830. The bearing housing 820 can be installed in the mounting frame 830. When the volute 320 is removed from the upper volute 350 and the lower volute 340, the bearing housing 820 can also be exposed from the air outlet 113, and the bearing housing 820 can also be inspected and repaired.

[0083] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the volute assembly 390 may include a volute body 330 and a volute cover 321, which are detachably connected to form an air cavity 360. The impeller 310 is installed in the air cavity 360, and the volute cover 321 is located at the air outlet 113.

[0084] The volute cover 321 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 and drive assembly 400 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.

[0085] The volute cover 321 is detachably connected to the volute body 330, and the volute cover 321 is located at the air outlet 113. If it is necessary to repair or replace the impeller 310 or the drive component 410, the volute cover 321 can be removed from the volute body 330, so that the impeller 310 can be exposed from the air outlet 113. The impeller 310 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.

[0086] The volute cover 321 is detachably connected to the volute body 330 to form an air cavity 360 for mounting the impeller 310. The impeller 310 is installed inside the air cavity 360. The volute body 330 is fixedly mounted on the housing 100. The volute cover 321 is detachably connected to the volute body 330. The volute cover 321 can be detachably connected to both the housing 100 and the volute body 330, or it can be detachably connected only to the volute body 330 without being connected to the housing 100. When it is necessary to inspect and repair the fan assembly 300, the connection between the volute cover 321 and the volute body 330 can be released, allowing the volute cover 321 to be removed from the receiving cavity 112, while the volute body 330 remains fixed inside the receiving cavity 112. After the volute cover 321 is removed, the impeller 310 can be exposed from the air outlet 113, allowing for direct inspection and repair of the impeller 310 from the air outlet 113.

[0087] 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 321 is located at the air outlet 113, the connection between the volute cover 321 and the volute body 330 is released, allowing the volute cover 321 to be removed from the receiving cavity 112, while the volute body 330 remains fixed within the receiving cavity 112. After the volute cover 321 is removed, the impeller 310 can be exposed from the air outlet 113, allowing for direct inspection of the impeller 310 from the air outlet 113.

[0088] As for how the volute cover 321 is removed from the volute body 330, the volute cover 321 can be removed along the air outlet direction, so that the volute cover 321 can be removed from the air outlet 113. The following will describe in detail how the volute cover 321 is assembled with the volute body 330 and how it is disassembled.

[0089] Please see Figure 7 , Figure 8 and Figure 9In some embodiments, the volute body 330 includes a first shell segment 341 and a second shell segment 351, the first shell segment 341 and the second shell segment 351 are connected, and both the first shell segment 341 and the second shell segment 351 are detachably connected to the volute cover 321.

[0090] The first shell section 341 and the second shell section 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 first shell section 341 is disposed below the second shell section 351 and is fixedly connected to the bottom plate 124. The second shell section 351 is connected to the first shell section 341 and to the top plate 122.

[0091] During assembly, an inverted method can be used. First, fix the second shell section 351 to the top plate 122, place the impeller 310 inside the second shell section 351, then snap the first shell section 341 onto the second shell section 351, and finally assemble the volute cover 321. This facilitates the assembly of the impeller 310.

[0092] In other words, in this embodiment of the application, the volute of the wind turbine assembly 300 is in the form of three sections (e.g., Figure 7 and Figure 8 The volute assembly 300 is composed of a first shell section 341, a second shell section 351, and a volute cover 321. This design facilitates the assembly and maintenance of the entire fan assembly 300. Alternatively, the volute can be in two sections, meaning the volute body 330 can be a single unit. Furthermore, the volute can also be in four sections or other forms; specific details are not limited.

[0093] Please see Figure 10 Regarding the connection method between the first shell segment 341 and the second shell segment 351, they can be snap-fitted or fixedly connected by screws or other fasteners. In some embodiments, the first shell segment 341 and the second shell segment 351 are snap-fitted. The following will describe in detail how the first shell segment 341 and the second shell segment 351 are snap-fitted.

[0094] In some embodiments, the first shell segment 341 is provided with a first retaining member 342, and the second shell segment 351 is provided with a second retaining member 352, wherein the first retaining member 342 and the second retaining member 352 are engaged.

[0095] Please see Figure 11 and Figure 12 Specifically, the second holding member 352 includes a holding portion 353, and the first holding member 342 is provided with a card hole 343, the holding portion 353 being able to engage with the card hole 343. The holding portion 353 includes a connecting section 353a and a card engaging section 353b protruding from the connecting section 353a, the connecting section 353a passing through the card hole 343, and the card engaging section 353b abutting against the first holding section.

[0096] The first retaining member 342 is also provided with a guide portion 347. During the assembly of the first shell section 341 and the second shell section 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 card hole 343.

[0097] In addition, of the two retaining members 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 first shell section 341 and the second shell section 351, but also seal the gap (air cavity 360) between the first shell section 341 and the second shell section 351, thereby reducing the possibility of air leakage between the first shell section 341 and the second shell section 351.

[0098] Please see Figure 13 and Figure 14 In some embodiments, one of the volute body 330 and the volute cover 321 is provided with a sliding groove 356 and the other is provided with a sliding rail 322, with the sliding rail 322 cooperating with the sliding groove 356.

[0099] In this design, one of the volute body 330 and the volute cover 321 is provided with a sliding groove 356, and the other is provided with a sliding rail 322. The sliding groove 356 can be provided on the volute body 330 and the sliding rail 322 on the volute cover 321, or vice versa. The specific arrangement is not limited. For ease of description, we will use the example of the volute body 330 having a sliding groove 356 and the volute cover 321 having a sliding rail 322 as an example. Similarly, the arrangement of the sliding rail 322 on the volute body 330 and the sliding groove 356 on the volute cover 321 can be deduced.

[0100] The slide rail 322 and the slide groove 356 work together to provide guidance. At the same time, the slide rail 322, inserted into the slide groove 356, also provides a certain degree of sealing, which can reduce the risk of air leakage between the volute body 330 and the volute cover 321.

[0101] The slide 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.

[0102] In some embodiments, at least one of the slide groove 356 and the slide rail 322 is inclined along the depth direction Y of the housing 100. The inclination of at least one of the slide groove 356 and the slide rail 322 along the depth direction Y of the housing 100 can be either only the slide groove 356, only the slide rail 322, or both the slide rail 322 and the slide groove 356 are arranged along the depth direction Y of the housing 100.

[0103] At least one of the slide groove 356 and slide rail 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 position the volute cover 321 so that the volute cover 321 can slide to the set position as much as possible.

[0104] Specifically, the slide 356 is provided on the second shell section 351, that is, the slide rail 322 is provided above the volute cover 321.

[0105] In some embodiments, the volute body 330 is provided with a stop surface 358, which can abut against the volute cover 321. The stop surface 358 is located on the side of the slide groove 356 away from the air outlet 113. During the assembly of the volute cover 321, the slide rail 322 slides along the slide groove 356. When the slide rail 322 slides to the stop surface 358, the slide rail 322 can abut against the stop surface 358, thereby facilitating the fixing of the volute cover 321 to the volute body 330. The stop surface 358 can be provided on the second shell section 351.

[0106] Among them, there are two slide rails 322 and slide grooves 356, which are respectively set on both sides along the axial direction of the impeller 310. They cooperate with the volute body 330 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 330.

[0107] Please see Figure 3 and Figure 14 In some embodiments, the volute body 330 is provided with a positioning part 345, and the volute cover 321 is provided with a positioning cover 323, which covers the positioning part 345. The positioning part 345 is located on the first shell section 341 and is located near the air outlet 113. When the slide rail 322 slides into place relative to the slide groove 356, the positioning cover 323 covering the positioning part 345 can seal the connection between the first shell section 341 and the volute cover 321, thereby reducing air leakage.

[0108] In some embodiments, the dimension of the volute cover 321 in the height direction Z of the housing 100 is larger than the diameter of the impeller 310. After the volute cover 321 is removed from the volute body 330, the impeller 310 can be directly removed from the volute body 330, which facilitates the inspection and replacement of the impeller 310.

[0109] In some embodiments, there are multiple impellers 310 and multiple volute covers 321, with the multiple volute covers 321 being integrally formed. The impellers 310 are centrifugal impellers 310. 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, thereby increasing the overall heat exchange effect of the air conditioner 10.

[0110] Since there are multiple wind turbines 310, and multiple wind turbines 310 correspond to multiple volute modules, that is, there are multiple volute covers 321, multiple first shell sections 341, and multiple second shell sections 351. Multiple volute covers 321 are integrally formed, multiple first shell sections 341 are integrally formed, and multiple second shell sections 351 are integrally formed.

[0111] For ease of description, the collective of multiple volute covers 321 is defined as the middle volute component 320, the collective of multiple first shell segments 341 is defined as the lower volute component 340, and the collective of multiple second shell segments 351 is defined as the upper volute component 350.

[0112] During assembly, the lower volute component 340 (the entirety of multiple first shell sections 341) is first installed on the base plate 124. Then, multiple impellers 310 are installed into their respective first shell sections 341. Next, the upper volute component 350 (the entirety of multiple second shell sections 351) is snapped onto the first shell section 341, forming multiple volute bodies 330. The upper volute component 350 (the entirety of multiple second shell sections 351) is connected to the top plate 122. Finally, the middle volute component 320 (the entirety of multiple volute covers 321) is assembled from the air outlet 113 onto the entirety of the first shell sections 341 and second shell sections 351.

[0113] Although multiple first shell segments 341 are integrally formed, multiple second shell segments 351 are integrally formed, and multiple volute covers 321 are integrally formed, a first shell segment 341, a second shell segment 351, and a volute cover 321 form a wind cavity 360, which is a volute module used to install a wind turbine 310. Therefore, it can be considered that a first shell segment 341, a second shell segment 351, a volute cover 321, and a wind turbine 310 form a wind turbine module.

[0114] The assembly method between individual first shell section 341 and second shell section 351 remains unchanged, the assembly method between individual first shell section 341 and volute cover 321 remains unchanged, and the assembly method between individual second shell section 351 and volute cover 321 remains unchanged.

[0115] Please see Figure 2 In some embodiments, the air conditioner 10 further includes a first fixing member 372 and a second fixing member 374. The first fixing member 372 is fixedly connected to the first shell section 341 and the volute cover 321, and the second fixing member 374 is fixedly connected to the second shell section 351 and the volute cover 321.

[0116] After the middle volute 320 is assembled onto the upper volute 350 and the lower volute 340, the middle volute 320 and the lower volute 340 can be fixed by the first fixing member 372, and the middle volute 320 and the upper volute 350 can be fixed by the second fixing member 374.

[0117] Among them, the first fixing member 372 and the second fixing member 374 can be screws. After the middle volute 320 is assembled to the upper volute 350 and the lower volute 340, screws can be driven directly from the air outlet 113 to fix the middle volute 320 to the upper volute 350 and the lower volute 340.

[0118] When disassembly is required, the air outlet grille 21 at the air outlet 22 can be removed first, and then the first fixing part 372 and the second fixing part 374 can be removed so that the middle volute 320 is released from the fixing relationship with the upper volute 350 and the lower volute 340 respectively. Then, the middle volute 320 can be pulled out along the air outlet direction.

[0119] Please see Figure 2 and Figure 7 In some embodiments, the air conditioner 10 further includes a drive assembly 400, which includes a drive member 410, a motor cover 420 and a motor base 430. The drive member 410 is connected to the impeller 310 in a transmission manner. The motor cover 420 and the motor base 430 are detachably connected and cover the drive member 410.

[0120] The drive unit 410 is connected to the fan wheel 310 and can drive the fan wheel 310 to rotate, so that air can flow through the inside of the air conditioner 10. The motor cover 420 and the motor base 430 are detachably connected, so that the drive unit 410 can be replaced or repaired in case of failure. The operation is simple and convenient.

[0121] In some embodiments, the motor cover 420 and the volute cover 321 are an integral structure. When the fan assembly 300 needs to be inspected, after removing the volute cover 321, since the motor cover 420 and the volute cover 321 are an integral structure, the motor cover 420 is also removed along with the volute cover 321. Only one operation is needed to expose the impeller 310 and the drive component 410, thereby enabling the inspection and maintenance of the impeller 310 and the drive component 410.

[0122] Because multiple volute covers 321 are integrally formed, that is, the motor cover 420 and the middle volute part 320 are integrally formed.

[0123] Since there are multiple wind turbines 310, the drive unit 410 needs to drive multiple wind turbines 310. The drive unit 410 may include a drive motor 412 and a transmission shaft 413. It can be connected to multiple wind turbines 310 through the transmission shaft 413, thereby realizing the simultaneous rotation of multiple wind turbines 310 by one drive unit 410. The motor base 430 and the motor cover 420 are used to fix and install the drive motor 412.

[0124] There are multiple wind turbines 310. The drive motor 412 can be positioned between two adjacent wind turbines 310. For example, when there are three wind turbines 310, for ease of description, they can be defined as the first wind turbine 310, the second wind turbine 310, and the third wind turbine 310 from left to right. The drive motor 412 can be positioned between the first wind turbine 310 and the second wind turbine 310, or between the second wind turbine 310 and the third wind turbine 310. Positioning the drive motor 412 in the middle position allows both ends of the drive motor 412 to drive the wind turbines 310, avoiding the possibility of deformation due to an excessively long drive shaft 413.

[0125] Please see Figure 15 As for the assembly structure of the motor cover 420 and the motor base 430, it is roughly as follows: In some embodiments, one of the motor cover 420 and the motor base 430 is provided with a positioning groove 421, and the other is provided with a positioning part 345, which passes through the positioning groove 421.

[0126] The positioning part 345 can be provided on the motor base 430, and the positioning groove 421 can be provided on the motor cover 420. Alternatively, the positioning groove 421 can be provided on the motor base 430, and the positioning part 345 can be provided on the motor cover 420. In either case, the positioning part 345 and the positioning groove 421 can cooperate to achieve the positioning of the motor cover 420 and the motor base 430. For ease of description, the embodiments of this application are described with the positioning part 345 provided on the motor base 430 and the positioning groove 421 provided on the motor cover 420 as an example. When the positioning part 345 is provided on the motor cover 420 and the positioning groove 421 is provided on the motor base 430, the same principle applies, and will not be described again.

[0127] Please see Figure 16 The positioning part 345 may include a guide section 431a and a positioning section 431b. One end of the positioning section 431b is connected to the motor base 430, and the other end of the positioning section 431b is connected to the guide section 431a. During the assembly of the motor cover 420 and the motor base 430, the guide section 431a can guide the positioning groove 421 to a certain extent, so that the positioning groove 421 can cooperate with the entire positioning part 345.

[0128] Specifically, the guide section 431a can be provided with an inclined guide surface 431c. Under the action of the guide surface 431c, the groove wall of the positioning groove 421 can slide along the inclined direction of the guide surface 431c, thereby enabling the positioning groove 421 to cooperate with the positioning groove 421.

[0129] As for the shape of the positioning groove 421 and the entire positioning part 345, they can be roughly matched. That is, if the cross-section of the positioning groove 421 is rectangular, then the shape of the positioning part 345 in the same cross-section can be roughly rectangular. If the cross-section of the positioning groove 421 is circular, then the shape of the positioning part 345 in the same cross-section is also roughly circular.

[0130] It should be noted that "approximately rectangular" means that the shape of the positioning part 345 in this cross-section is not necessarily a complete rectangle; it can be that the shape enclosed by the outermost structure of the positioning part 345 is rectangular.

[0131] During the assembly of the motor cover 420 and the motor base 430, the engagement of the positioning part 345 and the positioning groove 421 only serves to position the motor cover 420. In addition, a fixing structure is needed to fix the motor cover 420 and the motor base 430, as follows:

[0132] Please see Figure 16 In some embodiments, the motor cover 420 has a first connection hole 422, the motor base 430 has a second connection hole 432, and the air conditioner 10 also includes a connector that passes through the first connection hole 422 and the second connection hole 432.

[0133] The connectors can be screws, bolts, or similar structures, and their extension direction is approximately the same as the air outlet direction. This allows installers or maintenance personnel to secure the motor cover 420 and the motor base 430 from the air outlet 113, or to detach the motor cover 420 and the motor base 430. This facilitates operation by installers or maintenance personnel.

[0134] As for the number of connections, it can be set according to the shape and cross-sectional area of ​​the motor cover 420. For example, when the motor cover 420 is roughly rectangular, first connection holes 422 can be set at the four corners of the motor cover 420, and the number of connectors can be set to four. The four connectors fix the motor cover 420 and the motor base 430 from the four corners of the motor cover 420, which can increase the fixing strength between the motor cover 420 and the motor base 430 and reduce the risk of the motor cover 420 and the motor base 430 falling off.

[0135] When the connector is a screw, the second connecting hole 432 can be a threaded hole, while the first connecting hole 422 can be a through hole or a threaded hole. The screw passes through the first connecting hole 422 and engages with the thread in the second connecting hole 432, thereby fixing the motor and the motor base 430.

[0136] It should be noted that the positions of the first connecting hole 422 and the second connecting hole 432 are relatively fixed. When the positioning part 345 is engaged in the positioning groove 421, the first connecting hole 422 and the corresponding second connecting hole 432 are approximately connected. The position of the motor cover 420 can be finely adjusted so that the first connecting hole 422 and the corresponding second connecting hole 432 can be connected, and the connector can pass through the first connecting hole 422 and the second connecting hole 432.

[0137] In other words, when the motor cover 420 is installed, after the positioning part 345 is inserted into the positioning groove 421, the first fixing hole can be roughly connected with the corresponding second fixing hole. The position of the motor cover 420 can be finely adjusted so that the first fixing hole can be connected with the corresponding second fixing hole. The installation process is simple and convenient.

[0138] In some embodiments, at least a portion of the motor cover 420 overlaps with the volute body 330.

[0139] Since the motor cover 420 is partially located below the drive member 410, meaning the distance between the motor cover 420 and the volute body 330 is closest, at least a portion of the motor cover 420 overlaps the volute body 330, allowing a portion of the motor cover 420 to be positioned on the volute body 330, i.e., a portion of the motor cover 420 contacts the volute body 330. The volute body 330 can support a portion of the motor cover 420. The weight of the drive member 410 can be partially transferred to the volute body 330 through the contact between the motor cover 420 and the volute body 330, thus reducing the force on the top plate 122 connected to the motor base 430. This arrangement also reduces the risk of deformation of the top plate 122.
