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.

[0051] 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, 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 assembly is located inside the unit. If the fan assembly malfunctions, the entire ceiling must be removed for repair, resulting in high maintenance costs. The air conditioner provided in this application addresses these issues by changing the location of the fan assembly, thus facilitating its maintenance.

[0052] This application is described below with reference to the accompanying drawings and specific embodiments:

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 the impeller 310 through the air outlet 113 without damaging the original ceiling structure 20, which can reduce the inspection difficulty of the fan assembly 300 and facilitate the replacement and maintenance of the fan assembly 300 and the drive component 410.

[0058] The air conditioner 10 may include: a housing 100, a fan assembly 300, a drive unit 410, and a motor housing 460. 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 fan wheel 310, a volute body 330, and a volute cover 321. The volute body 330 and the volute cover 321 are detachably connected to form an air cavity 360. The fan wheel 310 is installed in the air cavity 360, and the volute cover 321 is located at the air outlet 113. The drive unit 410 and the motor housing 460 are both disposed in the receiving cavity 112. The drive unit 410 is connected to the fan wheel 310 in a transmission manner, and the motor housing 460 is detachably connected to the volute cover 321.

[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, with the side where the electronic control component 700 is located designated 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] 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.

[0064] 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 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.

[0065] 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 the impeller 310 needs to be repaired or replaced, the volute cover 321 can be removed from the volute body 330, so that the impeller 310, the drive component 410, and the motor housing 460 can be exposed from the air outlet 113. The impeller 310 and the drive component 410 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 the drive component 410, and facilitates the replacement and repair of the fan assembly 300 and the drive component 410.

[0066] 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.

[0067] Specifically, since the entire air conditioner 10 is installed within the ceiling structure 20, which has an air inlet 22 and a return air inlet 23, the air inlet 22 is connected to the air outlet 113, and the return air inlet 23 is connected to the air inlet 114. Both the air inlet 22 and the return air inlet 23 are equipped with grilles. When the fan assembly 300 needs to be inspected, the grille at the air inlet 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.

[0068] The motor housing 460 is detachably connected to the volute cover 321. Even after the volute cover 321 is removed from the volute body 330, the motor housing 460 remains attached to the drive motor 412, allowing the air conditioner 10 to independently inspect the impeller 310. Because the motor housing 460 is still integrated with the drive component 410 after the volute cover 321 is removed from the volute body 330, the motor housing 460 provides fixation and support for the drive component 410, thus reducing the likelihood of movement of the drive component 410 during impeller 310 maintenance.

[0069] In other words, in this embodiment, when the drive component 410 needs to be inspected, the volute cover 321 is first removed from the front of the housing 100 through the air outlet 113, allowing the motor housing 460 to be exposed through the air outlet 113. If the drive component 410 needs further inspection, the motor housing 460 is then removed to expose the drive component 410. Specifically, if the drive component needs inspection, the air outlet grille 21 at the air outlet 22 must first be removed, then the volute cover 321 removed, and finally the motor housing 460 removed to inspect the drive component 410.

[0070] Please see Figure 5 In some embodiments, the volute cover 321 is provided with a groove 324, and the motor housing 460 is provided with a fixing part 423, wherein the groove 324 and the fixing part 423 are detachably connected.

[0071] Along the air outlet direction, the groove 324 is recessed towards the receiving cavity 112. That is, when viewed from the direction of the air outlet 113, the groove 324 is recessed inward. This arrangement facilitates the connection between the volute cover 321 and the fixing part 423, allowing the connection structure between the fixing part 423 and the volute cover 321 to be accommodated within the groove 324. This minimizes the possibility of the connection structure between the fixing part 423 and the volute cover 321 protruding outside the volute cover 321, and minimizes the increase in the overall size of the air conditioner 10 in the depth direction Y. This allows the overall size of the air conditioner 10 in the depth direction Y to be as small as possible, enabling the air conditioner 10 to be miniaturized and installed in a smaller space.

[0072] In addition, in some other embodiments, the groove 324 may not be provided on the volute cover 321, so that the volute cover 321 can be directly and detachably fixedly connected to the fixing part 423.

[0073] In some embodiments, the groove 324 is provided with a first fixing hole 325, the fixing part 423 is provided with a second fixing hole 424, and the air conditioner 10 also includes a fixing member 450, which passes through the first fixing hole 325 and the second fixing hole 424.

[0074] The first fixing hole 325 is provided on the bottom surface of the groove 324, which is opposite to the air outlet 113. When the air outlet grille 21 in the ceiling is removed, the groove 324 will be exposed from the air outlet 113, that is, the bottom surface of the groove 324 will be exposed from the air outlet 113. The first fixing hole 325 is provided on the bottom surface of the groove 324. When the air outlet grille 21 is removed, the fixing part 450 can also be exposed from the air outlet 113, which facilitates the disassembly and assembly of the volute cover 321 and the motor housing 460.

[0075] The fastener 450 can be a screw, bolt, or similar structure, and its extension direction is approximately the same as the air outlet direction. This allows installers or maintenance personnel to secure the volute cover 321 and the motor housing 460 from the air outlet 113, or to separate them. This facilitates operation by installers or maintenance personnel.

[0076] The number of fasteners 450 can be determined based on the shape and cross-sectional area of ​​the groove 324. For example, when the bottom surface of the groove 324 is rectangular, first fixing holes 325 can be provided at the four corners of the bottom surface, and the number of fasteners 450 can be set to four. The four fasteners 450 fix the volute cover 321 and the motor housing 460 from the four corners of the bottom surface, which can increase the fixing strength between the volute cover 321 and the motor housing 460 and reduce the risk of the volute cover 321 and the motor housing 460 falling off.

[0077] As for the structure of the fixing part 423, the fixing part 423 can protrude from the motor housing 460, so that the fixing part 423 has a certain length in the depth direction Y of the housing 100, so that the second fixing hole 424 has a certain depth in the fixing part 423, thereby allowing the fixing member 450 to be inserted into the second fixing hole 424 to a sufficiently long depth, and also improving the connection strength between the fixing member 450 and the fixing part 423 and the volute cover 321.

[0078] When the fastener 450 is a screw, the second fixing hole 424 can be a threaded hole, and the first fixing hole 325 can be a through hole or a threaded hole. The screw passes through the first fixing hole 325 and engages with the thread in the second fixing hole 424, thereby fixing the groove 324 and the motor housing 460.

[0079] It should be noted that the positions of the first fixing hole 325 and the second fixing hole 424 are relatively fixed. When the volute cover 321 is installed on the volute body 330, the first fixing hole 325 is connected to the corresponding second fixing hole 424, and the fastener 450 can pass through the first fixing hole 325 and the second fixing hole 424.

[0080] In other words, when the volute cover 321 is installed, once the volute cover 321 is fixedly connected to the volute body 330, the first fixing hole 325 can communicate with the corresponding second fixing hole 424. There is no need to separately position the first fixing hole 325 and the second fixing hole 424, making the installation process simple and convenient.

[0081] Please see Figure 6 and Figure 7 The above describes how to install and remove the volute cover 321 from the entire motor housing 460. The following will describe how to disassemble and repair the drive component 410. The specific disassembly, assembly, and repair of the drive component 410 are as follows:

[0082] In some embodiments, the motor housing 460 includes a motor cover 420 and a motor base 430, a drive member 410 is mounted on the motor base 430, the motor cover 420 covers the drive member 410, the motor base 430 is mounted on the housing 100, the motor cover 420 is detachably connected to the motor base 430, and the motor cover 420 is detachably connected to the volute cover 321.

[0083] The motor mount 430 can be fixed to the top plate 122 of the housing 100. Since the entire air conditioner 10 is installed in the ceiling, the installation position of the air conditioner 10 is relatively high. Installers or maintenance personnel mainly operate in front of or below the air conditioner 10. The motor mount 430 can be fixed to the top plate 122 of the housing 100, which makes it convenient for installers or maintenance personnel to inspect and repair the drive component 410.

[0084] The motor cover 420 is detachably connected to the motor base 430. When the drive component 410 needs maintenance, the connection between the motor cover 420 and the motor base 430 can be disconnected, so that the drive component 410 can be exposed from the air outlet 113, thereby facilitating the maintenance or replacement of the drive component 410.

[0085] For the drive component 410, the motor mount 430 is located above and behind the drive component 410, and the motor cover 420 is located in front of and below the drive component 410. In case of repair or replacement of the drive component 410, the volute cover 321 can be removed from the volute body 330 first, and then the motor cover 420 can be removed from the motor mount 430, allowing the drive component 410 to be exposed from the air outlet 113, thus facilitating the inspection or replacement of the drive component 410.

[0086] Please see Figure 8 and Figure 9 Specifically, the volute cover 321 and the motor cover 420 are detachably connected, that is, the fixing part 423 is provided on the motor cover 420 and is provided on the side of the motor cover 420 near the volute body 330, so that the fixing part 423 and the groove 324 can be fixedly connected.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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:

[0094] 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 further includes a connector that passes through the first connection hole 422 and the second connection hole 432.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 325 can be roughly connected with the corresponding second fixing hole 424. The position of the motor cover 420 can be finely adjusted so that the first fixing hole 325 can be connected with the corresponding second fixing hole 424. The installation process is simple and convenient.

[0100] In some embodiments, at least a portion of the motor cover 420 overlaps with the volute body 330.

[0101] 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.

[0102] Please see Figure 4 and Figure 10 In some embodiments, the volute body 330 includes a lower volute 341 and an upper volute 351, the lower volute 341 is connected to the upper volute 351, and both the lower volute 341 and the upper volute 351 are detachably connected to the volute cover 321.

[0103] 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.

[0104] 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.

[0105] 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 4 As shown, the fan assembly 300 consists of a lower volute 341, an upper volute 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.

[0106] Please see Figure 11 and Figure 12 Regarding the connection method between the lower volute 341 and the upper volute 351, they can be snap-fitted together or fixedly connected by screws or other fasteners 450. 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.

[0107] Please see Figure 13 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.

[0108] Please see Figure 14 and Figure 15 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.

[0109] 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.

[0110] 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 360) between the lower volute 341 and the upper volute 351, thereby reducing air leakage between the lower volute 341 and the upper volute 351.

[0111] Please see Figure 16 , Figure 17 and Figure 18 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] Specifically, the slide groove 356 is provided on the upper volute 351, that is, the slide rail 322 is provided above the volute cover 321.

[0118] 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 upper volute 351.

[0119] 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.

[0120] Please refer to the figure. Figure 10 and Figure 15 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 lower volute 341 and is close to 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 lower volute 341 and the volute cover 321, thereby reducing air leakage.

[0121] 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.

[0122] Please see Figure 4In 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.

[0123] Since there are multiple impellers 310, and multiple impellers 310 correspond to multiple volute modules, that is, there are multiple volute covers 321, multiple lower volutes 341, and multiple upper volutes 351. Multiple volute covers 321 are integrally formed, multiple lower volutes 341 are integrally formed, and multiple upper volutes 351 are integrally formed.

[0124] For ease of description, the collective of multiple volute covers 321 is defined as the middle volute component 320, the collective of multiple lower volutes 341 is defined as the lower volute component 340, and the collective of multiple upper volutes 351 is defined as the upper volute component 350.

[0125] During assembly, the lower volute component 340 (the entire assembly of multiple lower volutes 341) is first installed on the base plate 124. Then, multiple impellers 310 are installed into their respective lower volutes 341. Next, the upper volute component 350 (the entire assembly of multiple upper volutes 351) is snapped onto the lower volute 341, forming multiple volute bodies 330. The upper volute component 350 (the entire assembly of multiple upper volutes 351) is connected to the top plate 122. Finally, the middle volute component 320 (the entire assembly of multiple volute covers 321) is assembled from the air outlet 113 onto the entire assembly of the lower volutes 341 and the upper volutes 351.

[0126] Although multiple lower volutes 341 are integrally formed, multiple upper volutes 351 are integrally formed, and multiple volute covers 321 are integrally formed, a lower volute 341, an upper volute 351, and a volute cover 321 form a wind cavity 360, which is a volute module used to install a fan wheel 310. That is, a lower volute 341, an upper volute 351, a volute cover 321, and a fan wheel 310 can be considered to form a fan module.

[0127] The assembly method between a single lower volute 341 and an upper volute 351 remains unchanged, the assembly method between a single lower volute 341 and a volute cover 321 remains unchanged, and the assembly method between a single upper volute 351 and a volute cover 321 remains unchanged.

[0128] Multiple lower volutes 341 form a lower volute component 340. A motor cover 420 overlaps the lower volute component 340 and is positioned between two adjacent lower volutes 341. The motor cover 420 is positioned above the lower volute component 340. The lower volute component 340 can support part of the motor cover 420. The weight of the drive component 410 can be partially transferred to the lower volute component 340 through the contact between the motor cover 420 and the lower volute component 340, so that the top plate 122 connected to the motor base 430 bears less force. This arrangement can also reduce the risk of deformation of the top plate 122.

[0129] 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 lower volute 341 and the volute cover 321, and the second fixing member 374 is fixedly connected to the upper volute 351 and the volute cover 321.

[0130] 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.

[0131] 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.

[0132] When disassembly is required, the air outlet grille 21 at the air vent 22 can be removed first, followed by the removal of the first fixing member 372 and the second fixing member 374. This releases the middle volute 320 from its fixing to the upper volute 350 and the lower volute 340, respectively. Then, the middle volute 320 can be pulled out along the air outlet direction. In other words, when the drive assembly 400 or the impeller 310 needs to be inspected, the operator only needs to remove the air outlet grille 21, exposing the surface of the air outlet 113 of the air conditioner 10 through the air vent 22. Since the first fixing member 372 and the second fixing member 374 are screwed from front to back, the operator can directly remove the first fixing member 372 and the second fixing member 374 from the front. This operation method allows the operator to directly remove the middle volute 350 from the front of the air conditioner 10, making the operation simple and convenient.

[0133] In summary, if maintenance of the impeller 310 and drive component 410 is required, first disconnect the connection between the volute cover 321 and the motor cover 420 (loosen the fastener 450 and remove it from the first fixing hole 325 and the second fixing hole 424), thus separating the volute cover 321 from the motor cover 420. Then remove the volute cover 321 from the volute body 330, allowing the impeller 310 to be exposed from the air outlet 113 for maintenance. If the drive component 410 also needs maintenance, disconnect the connection between the motor cover 420 and the motor base 430 (loosen the connector and remove it from the first connecting hole 422 and the second connecting hole 432), allowing the motor cover 420 and the motor base 430 to separate, and the drive component 410 to be exposed from the air outlet 113 for easy maintenance.
