[0048] This application is described below with reference to the accompanying drawings and specific embodiments:

[0049] Please see Figure 1 This application provides a fan module 303, which can be assembled or disassembled with ease, thereby facilitating the maintenance or replacement of the impeller 310.

[0050] In this embodiment, the fan module 303 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 a wind cavity 312, and the fan wheel 310 is installed in the wind cavity 312. The volute cover 321 is slidably engaged with the volute body 330.

[0051] Among them, the volute body 330 and the volute cover 321 are the volute of the entire fan module 303. The impeller 310 can be installed in the air cavity 312 formed by the two. The impeller 310 can be a centrifugal impeller 310. The centrifugal impeller 310 can axially intake air and radially exhaust air, and can generate a larger impeller 310 with lower energy consumption, thereby increasing the air volume of the entire fan module 303.

[0052] The volute cover 321 is detachably connected to the volute body 330, which facilitates the maintenance of the impeller 310. When the volute cover 321 is removed from the volute body 330, most of the axial structure of the impeller 310 can be exposed, which facilitates the maintenance of the impeller 310.

[0053] The volute cover 321 is provided with an air vent 301, through which air from the air chamber 312 can be blown out. The volute cover 321 and the volute body 330 are in a sliding fit, meaning that the volute cover 321 can slide relative to the volute body 330. For example, when removing the volute cover 321 from the volute body 330, the volute cover 321 slides away from the volute body 330, separating the volute cover 321 from the volute body 330, thus allowing the volute cover 321 to be removed from the volute body 330. Similarly, when it is necessary to assemble the volute cover 321, the volute cover 321 can slide along the direction close to the volute body 330, ultimately allowing the volute cover 321 to be assembled onto the volute body 330.

[0054] The slidable engagement between the volute cover 321 and the volute body 330 allows the volute cover 321 to slide and connect with the volute body 330 during assembly or disassembly. This sliding motion also helps to position the volute cover 321 during assembly or disassembly, reducing the likelihood of it falling directly off the volute body 330. This simplifies assembly or disassembly and facilitates the maintenance or replacement of the impeller 310.

[0055] Regarding the method of removing the volute cover 321 from the volute body 330, the volute cover 321 can be removed along the radial direction of the impeller 310, that is, the air outlet direction of the impeller 310. This allows the entire axial length of the impeller 310 to be exposed, facilitating the maintenance of the impeller 310. The following will describe in detail how the volute cover 321 is assembled with and disassembled from the volute body 330.

[0056] Please see Figure 2 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.

[0057] During assembly, an inverted method can be used, placing the impeller 310 inside the upper volute 351, then snapping the lower volute 341 onto the upper volute 351, and finally assembling the volute cover 321. This facilitates the assembly of the impeller 310.

[0058] In other words, in this embodiment, the volute of the fan 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 fan assembly 300. Alternatively, the volute can also be a two-section structure, where the volute body 330 is a single unit. Furthermore, the volute can also be a four-section structure or other forms; specific details are not limited.

[0059] Please see Figure 1 In some embodiments, the fan module 303 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.

[0060] The first fixing member 372 is fixedly connected to the lower volute 341 and the volute cover 321 along the air outlet direction (radial) of the impeller 310, and the second fixing member 374 is fixedly connected to the upper volute 351 and the volute cover 321 along the air outlet direction of the impeller 310. This ensures that the fixing direction of the first fixing member 372 and the second fixing member 374 is the same as the disassembly and assembly direction of the volute cover 321, allowing the operator to install or remove the first fixing member 372, the second fixing member 374, and the volute cover 321 in the same direction.

[0061] For example, when it is necessary to disassemble the volute cover 321, the operator can first remove the first fixing part 372 and the second fixing part 374 to release the fixed relationship between the volute cover 321 and the lower volute 341 and the upper volute 351, and then pull the volute cover 321 outward so that the volute cover 321 can be removed from the volute body 330.

[0062] After the impeller 310 is overhauled, the volute cover 321 is assembled onto the volute body 330. The lower volute 341 and volute cover 321 are then secured using the first fastener 372, and the upper volute 351 and volute cover 321 are secured using the second fastener 374. Throughout the disassembly or installation process, the operator can assemble the volute cover 321 with almost no movement, making the operation simple and convenient.

[0063] The first fixing member 372 and the second fixing member 374 can be screws. After the volute cover 321 is assembled to the lower volute 341 and the upper volute 351, screws can be driven directly from the front of the volute cover 321 to fix the volute cover 321 to the lower volute 341 and the upper volute 351.

[0064] Please see Figure 3 and Figure 4 Regarding 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.

[0065] Please see Figure 5 , Figure 6 and Figure 7 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.

[0066] 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 first retaining section.

[0067] 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.

[0068] 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 312) 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.

[0069] Please see Figure 3 and Figure 4 In some embodiments, one of the volute body 330 and the volute cover 321 is provided with a sliding groove 359 and the other is provided with a sliding rail 322, with the sliding rail 322 cooperating with the sliding groove 359.

[0070] In this design, one of the volute body 330 and the volute cover 321 is provided with a sliding groove 359, and the other is provided with a sliding rail 322. The sliding groove 359 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 359 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 359 on the volute cover 321 can be deduced.

[0071] The slide rail 322 and the slide groove 359 work together to provide guidance. At the same time, the slide rail 322, inserted into the slide groove 359, can also provide a certain sealing effect, which can reduce the risk of air leakage between the volute body 330 and the volute cover 321.

[0072] The slide 359 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 of the air conditioner 10, the air outlet direction is consistent with the depth direction Y of the housing 100.

[0073] In some embodiments, at least one of the slide groove 359 and the slide rail 322 is inclined along the depth direction Y of the housing 100. The inclined arrangement of at least one of the slide groove 359 and the slide rail 322 along the depth direction Y of the housing 100 can be either only the slide groove 359, only the slide rail 322, or both the slide rail 322 and the slide groove 359 are arranged along the depth direction Y of the housing 100.

[0074] At least one of the slide groove 359 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.

[0075] Specifically, the slide groove 359 is provided on the upper volute 351, that is, the slide rail 322 is provided above the volute cover 321.

[0076] In some embodiments, the volute body 330 is provided with a stop surface 358, which can abut against the volute cover 321. During the assembly of the volute cover 321, the slide rail 322 slides along the slide groove 359. When the volute cover 321 abuts against the stop surface 358, it can be considered that the slide rail 322 has slid into place relative to the slide groove 359. After the volute cover 321 abuts against the stop surface 358, the volute cover 321 and the volute body 330 can be fixedly connected. This method facilitates the fixing of the volute cover 321 and the volute body 330. The stop surface 321 can be provided on the upper volute 351.

[0077] Among them, there are two slide rails 322 and slide grooves 359, 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.

[0078] Please see Figure 4 and Figure 8In 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 359, 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.

[0079] Please see Figure 9 , Figure 10 and Figure 11 In another embodiment, the volute body 330 has a first mounting section 831, the volute cover 321 has a second mounting section 832, the first mounting section 831 and the second mounting section 832 form a mounting frame 830, and the bearing seat 820 can be installed in the fixed cavity of the mounting frame 830.

[0080] Specifically, the first mounting section 831 can be installed on the upper volute 351.

[0081] When the fan module 303 is applied to equipment such as the air conditioner 10, multiple fan modules 303 can be set up to increase the overall air volume of the air conditioner 10. To achieve a more compact structural layout, multiple different fan modules 303 can be driven by a single motor driving the transmission shaft. Bearing housings are needed to fix the end of the drive motor. The mounting structure of directly setting the bearing housings on the volute body 330 and volute cover 321 facilitates the layout of the bearing housings, making the structure more compact and centralized. Furthermore, when the volute cover 321 is removed from the volute body 330, the bearing housings can be exposed, allowing for inspection and maintenance.

[0082] The first mounting section 831 is integrally formed with the upper volute 351, and the second mounting section 832 is integrally formed with the volute cover 321. The integral forming method allows the mounting bracket 830 and the fan module 303 to be a whole, eliminating the need to assemble the mounting bracket 830 structure separately, thus reducing assembly steps.

[0083] Based on the same inventive concept, this application also provides an air conditioner 10, wherein the entire air conditioner 10 is installed within the ceiling structure 20 (e.g., Figure 12 As shown, an air outlet 22 connected to the air outlet 113 and a return air outlet 2323 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 2323. After heat exchange by the heat exchanger 500, it is blown into the room through the air outlet 113 and the air outlet 22.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] Please see Figure 13 and Figure 14 In some embodiments, the air conditioner 10 includes: a housing 100, a heat exchanger 500, and a fan assembly 300. 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, 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 312. The fan wheel 310 is installed in the air cavity 312, and the volute cover 321 is located at the air outlet 113.

[0088] 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.

[0089] 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.

[0090] 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". The electrical control component 700 is located at one end of the housing 100 along the width direction X. Along the width direction X, the side where the electrical control component 700 is located is "right", and the other side is "left". The axial direction of the fan module 303 is the same as the width direction of the housing 100.

[0091] 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.

[0092] In the heat exchanger 500 and the fan assembly 300, the fan assembly 300 is positioned closer to the air outlet 113. The air blown from the fan assembly 300 can be directly directed into the indoor environment through the air outlet 113 without passing through other components, reducing airflow loss and thus increasing the overall air delivery distance of the air conditioner 10. Furthermore, since the air blown from the fan assembly 300 does not pass through the heat exchanger 500, the static pressure resistance of the entire air conditioner 10 is also improved.

[0093] 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.

[0094] 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, 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.

[0095] The volute cover 321 is detachably connected to the volute body 330 to form an air cavity 312 for mounting the impeller 310. The impeller 310 is installed inside the air cavity 312. 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.

[0096] Specifically, since the entire air conditioner 10 is installed within the suspended ceiling, 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.

[0097] Please see Figure 15 , Figure 16 and Figure 17 The fan assembly may include one or more fan modules 303. When there are multiple fan modules 303, two adjacent volute covers 321 are connected. Specifically, each end of the volute cover 321 is provided with a limiting part 327 and a limiting groove 326. In two adjacent fan modules 303, the limiting part 327 of one fan module 303 cooperates with the limiting groove 326 of the other fan module 303. The cooperation of the limiting groove 326 and the limiting part 327 allows multiple fan modules 303 to be connected to form a whole. During assembly and disassembly, multiple volute covers 321 can be disassembled and assembled simultaneously.
