Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0034] The air handling equipment provided in the embodiments of this application, such as Figures 1 to 6 As shown, it includes: a main body 1000, the front end of the main body 1000 is provided with a first air outlet 1211 and the interior is provided with a receiving cavity, the first air outlet 1211 is connected to the receiving cavity; and a fan assembly 200, the fan assembly 200 is configured to be installed into the receiving cavity through the first air outlet 1211 on the front side of the main body 1000, and the fan assembly 200 is also configured to be disassembled from the receiving cavity to the front side of the main body 1000 through the first air outlet 1211.

[0035] The air handling unit has a fan assembly 200 that can be installed into a receiving cavity through a first air outlet 1211 at the front of the main body 1000. The fan assembly 200 is also designed to be detached from the receiving cavity through the first air outlet 1211 towards the front of the main body 1000. This allows for easy removal of the fan assembly 200 from the receiving cavity through the first air outlet 1211 in case of malfunction. In this case, the grille on the indoor ceiling at the first air outlet 1211 can be removed (exposing the front of the air handling unit), and the fan assembly 200 can be removed from the receiving cavity through the first air outlet 1211 towards the front of the main body 1000. 11. The fan assembly 200 can be disassembled and inspected from the outside of the main body 1000. After the fan assembly 200 is inspected, it can be installed into the receiving cavity from the front of the main body 1000 through the first air outlet 1211. The whole process does not require damage to the indoor ceiling structure (that is, this solution allows the fan assembly 200 to be inspected through the window of the grille installed on the ceiling via the first air outlet 1211). Therefore, this solution can reduce the need to open a special maintenance port for the air handling equipment in the indoor ceiling.

[0036] In some examples, such as Figures 2 to 5 As shown, the main body 1000 includes: a shell 1100 with a first opening 1110 at its front end and a first cavity inside; and a spray assembly 1200. The spray assembly 1200 is located on the front side of the shell 1100. The spray assembly 1200 is provided with a water spraying and air passing channel 1213. The water spraying and air passing channel 1213 is located on the front side of the first opening 1110 and is arranged in the front-back direction. The water spraying and air passing channel 1213 is connected to the first cavity through the first opening 1110. The receiving cavity includes the first cavity, the first opening 1110 and the water spraying and air passing channel 1213. The first air outlet 1211 is located at the end of the water spraying and air passing channel 1213 away from the first opening 1110. The projection area of ​​the first opening 1110 along the first direction is located inside the projection area of ​​the water spraying and air passing channel 1213 along the first direction. The rear part of the fan assembly 200 extends into the first cavity from the first opening 1110. That is, the rear part of the fan assembly 200 can be installed into the first cavity through the water spraying and air passing channel 1213 on the front side of the main body 1000. The rear part of the fan assembly 200 can also be disassembled from the first cavity to the front side of the main body 1000 through the water spraying and air passing channel 1213.

[0037] In some embodiments, such as Figure 6 and Figure 12 As shown, the spray assembly 1200 also includes a spray nozzle 1212, which is located on the inner top surface of the water spray air passage 1213 and faces downwards. Figure 1 , Figure 2 , Figure 7 and Figure 14As shown, the main body 1000 also includes a wet film assembly 300, which is configured to be installed into the water spraying and air passage 1213 through the first air outlet 1211 on the front side of the main body 1000. The wet film assembly 300 is also configured to be detached from the water spraying and air passage 1213 through the first air outlet 1211 to the front side of the main body 1000. In this way, when the wet film assembly 300 needs to be replaced, the grille installed at the first air outlet 1211 on the indoor ceiling is removed, the wet film assembly 300 in the water spray air passage 1213 on the front side of the main body 1000 is removed from the first air outlet 1211, and then the new wet film assembly 300 is installed in the water spray air passage 1213 on the front side of the main body 1000. The whole process does not require damage to the indoor ceiling structure (that is, this solution replaces the wet film assembly 300 through the window of the grille installed on the ceiling via the first air outlet 1211). Therefore, this solution can further reduce the need to open a special maintenance port for the air handling equipment in the indoor ceiling.

[0038] Among them, such as Figures 1 to 3 As shown, when the fan assembly 200 is installed in the receiving cavity and the wet film assembly 300 is installed in the water spraying and air passage 1213, the wet film assembly 300 is located in front of the fan assembly 200 and directly below the spray nozzle 1212.

[0039] In some embodiments, such as Figure 2 and Figure 11 As shown, the water spraying and air passage 1213 is provided with a first stop and a second stop. The second stop is located behind the first stop. The periphery of the wet film assembly 300 is squeezed from front to back across the first stop and positioned between the first stop and the second stop, so that the wet film assembly 300 is snapped into the water spraying and air passage 1213. This solution makes the assembly and disassembly process of the wet film assembly 300 simpler at the first opening 1110.

[0040] It can be, such as Figure 2 and Figure 11 As shown, the first stop portion consists of multiple first stop ribs spaced apart circumferentially along the water spray and air passage 1213. Each of the multiple first stop ribs has a guide surface on its front side. The guide surface is configured to guide the periphery of the wet film assembly 300 to be squeezed past the first stop ribs from front to back. The second stop portion consists of multiple second stop ribs spaced apart circumferentially along the water spray and air passage 1213. This scheme has a simple structure, and the multiple first stop ribs and multiple second stop ribs have a good positioning effect on the wet film assembly 300.

[0041] In some embodiments, such as Figures 3 to 5As shown, the fan assembly 200 includes: a volute housing disposed within a receiving cavity, with its axis arranged vertically; a third air inlet 211 on the front of the volute housing's peripheral wall and a fourth air inlet 222 on its end wall; the volute housing passing through a first opening 1110; the third air inlet 211 being located in front of the first opening 1110; a first screw passing through the wall of the third air inlet 211 and screwed onto the wall of the first opening 1110; the fourth air inlet 222 being located within the first cavity; the housing 1100 also includes a second air inlet 1130; the first cavity connecting the second air inlet 1130 and the fourth air inlet 222; a fan impeller 230 disposed within the volute housing; and a motor 240, which is connected to the fan impeller 230 in a driving connection. In this design, the axis of the fan assembly 200 is arranged vertically, resulting in a smaller vertical height for the fan assembly 200. Among them, the first air outlet 1211 and the third air outlet 211 are both set as air outlets, and the second air outlet and the fourth air outlet 222 are both set as air inlets.

[0042] In some embodiments, such as Figure 4 As shown, the volute includes: a folded plate 210, which includes a horizontal plate and a vertical plate connected together. The horizontal plate is arranged horizontally and passes through the first opening 1110. The vertical plate is erected vertically in the left-right direction and located outside the first cavity, and the vertical plate is provided with a third air vent 211; a cover 220, which is located behind the vertical plate. The cover 220 and the horizontal plate are arranged sequentially in the vertical direction, and the cover 220 includes a cover peripheral wall and a cover end wall. The front part of the cover peripheral wall is provided with a second opening 221, and the axis of the cover peripheral wall is along... Arranged vertically, the end wall of the cover is located at the end of the cover's peripheral wall facing away from the horizontal plate and has a fourth air vent 222. The end of the cover's peripheral wall facing the horizontal plate is connected to the side of the horizontal plate. The second opening 221 is connected to the third air vent 211. The impeller 230 and the motor 240 are located inside the area enclosed by the cover 220 and the horizontal plate, and the motor 240 is fixed to the horizontal plate. The first screw passes through the vertical plate from front to back and is screwed onto the opening wall of the first opening 1110, thereby fixing the fan assembly 200 to the housing 1100. The fan assembly 200 also includes a motor cover 250, which is located between the motor 240 and the impeller 230 and covers the motor 240 on the horizontal plate. Furthermore, the vertical plate has a wire passage hole, and a wire passage rubber ring 270 is fitted inside the wire passage hole.

[0043] The first screw includes multiple screws arranged circumferentially in the water spray air passage 1213, and the multiple screws can be two, three or four (e.g., ...). Figure 4 and Figure 5 As shown above, all of the above can achieve the purpose of this application. Their purpose has not deviated from the design concept of this utility model, and will not be repeated here. They should all fall within the protection scope of this application.

[0044] In some embodiments, such as Figures 3 to 5 As shown, one of the housing 1100 and the volute is provided with a guide positioning groove 1120 and the other is provided with a guide positioning rib 212. The guide positioning rib 212 and the guide positioning groove 1120 are connected in the front-to-back direction in the first cavity to guide the fan assembly 200 into the housing 1100 from front to back, and to position the part of the fan assembly 200 that extends into the housing 1100 inside the housing 1100, so as to prevent the part of the fan assembly 200 that extends into the housing 1100 from shaking inside the housing 1100.

[0045] Among them, such as Figures 3 to 5 As shown, the guide positioning groove 1120 includes two slots spaced apart in the left-right direction. The openings of the two slots are opposite each other in the left-right direction, and the front ends of both slots are through. The guide positioning rib 212 includes two insert ribs spaced apart in the left-right direction. The two insert ribs and the two slots are connected one-to-one in the front-back direction. Alternatively, two insert ribs can be formed at the left and right ends of the horizontal plate, which is a simpler structure. The rear end of the insert rib is provided with a shock-absorbing pad 260, which separates the insert rib from the groove wall of the slot.

[0046] In some examples, such as Figure 2 As shown, the spray assembly 1200 includes: a water receiving tray 1220, located at the lower front side of the housing 1100; and a water channel mechanism 1210 with spray nozzles 1212, located at the upper front side of the housing 1100, and forming a water spray and air passage 1213 together with the water receiving tray 1220. Figure 2 As shown, the inner bottom surface of the water receiving tray 1220 is provided with a support boss 1221, and the wet film assembly 300 is placed on the support boss 1221. Wherein, as... Figure 2 , Figure 11 and Figure 12 As shown, a portion of the second stop ribs are provided on the platform of the supporting boss 1221, and another portion of the second stop ribs are provided on the water channel mechanism 1210.

[0047] In some examples, such as Figure 9 , Figure 11As shown, the water system mechanism 1210 includes a water system support and a valve body module 1260. The water system support includes a top wall 1230, a first side wall 1240, and a second side wall 1250. The first side wall 1240 and the second side wall 1250 are erected in the front-back direction and are opposite to each other in the left-right direction. The left and right ends of the top wall 1230 are connected to the upper ends of the first side wall 1240 and the upper ends of the second side wall 1250 respectively. A first groove 1241 is provided on the side of the first side wall 1240 facing away from the second side wall 1250. The opening of the first groove 1241 faces away from the side where the second side wall 1250 is located. A third opening 1242 is provided on the front side of the first groove 1241. The valve body module 1260 is configured to be inserted into the first groove 1241 through the third opening 1242 on the front side of the first sidewall 1240, and is also configured to be detached from the first groove 1241 through the third opening 1242 towards the front side of the first sidewall 1240. Thus, in case of a malfunction of the valve body module 1260, the grille located at the first air vent 1211 on the indoor ceiling can be removed, and the valve body module 1260 can be detached from the first groove 1241 through the third opening 1242 on the front side of the water pipe bracket, achieving the following: The valve body module 1260 is inspected from the outside of the body 1000. After the valve body module 1260 is inspected, it is then installed into the first groove 1241 from the third opening 1242 on the front side of the water circuit bracket. The whole process does not require damage to the indoor ceiling structure (that is, this solution inspects the valve body module 1260 through the window of the grille installed on the ceiling via the third opening 1242). Therefore, this solution can further reduce the need to open a special maintenance port for the air handling equipment in the indoor ceiling.

[0048] In some embodiments, such as Figure 9 and Figure 11 As shown, the valve body module 1260 includes: a control valve 1261; and a valve bracket 1262. The control valve 1261 is disposed on the valve bracket 1262, and the valve bracket 1262 is installed in the first groove 1241. Compared with the control valve 1261 being disassembled and assembled separately in the first groove 1241, the operation of disassembling and assembling the valve bracket 1262 in the first groove 1241 is easier.

[0049] In some embodiments, such as Figure 9 and Figure 11As shown, the valve bracket 1262 includes: a first bracket plate 1264, on which a control valve 1261 is mounted; a plug-in portion 1265 is provided at the rear end of the first bracket plate 1264; a plug-in mating portion is provided on the rear side wall of the first groove 1241; the plug-in portion 1265 is plugged into the plug-in mating portion in the front-rear direction; and a second bracket plate 1263, located below the front side of the third opening 1242 and connected to the front end of the first bracket plate 1264; a third screw passes through the second bracket plate 1263 from front to back and is screwed onto the front end face of the first side wall 1240 below the third opening 1242. Thus, by removing the third screw from the front side of the water channel bracket, the valve bracket 1262 can be disassembled from the third opening 1242 towards the front side of the water channel bracket. The control valve 1261 is a solenoid valve.

[0050] In some examples, such as Figures 9 to 12 As shown, the rear part of the lower sidewall of the first groove 1241 is provided with a first mounting hole 1245 that extends vertically. The water circuit mechanism 1210 also includes a pump body module 1270, which is configured to be inserted into the first mounting hole 1245 through the third opening 1242 and the first groove 1241 on the front side of the first sidewall 1240, and is also configured to be disassembled from the first mounting hole 1245 through the first groove 1241 and the third opening 1242 to the front side of the first sidewall 1240. In case of pump body module 1270 malfunction, the grille set at the first air vent 1211 on the indoor ceiling is removed, and the valve body module 1260 and the pump body module 1270 in the first groove 1241 are sequentially inserted from the third opening 1242 on the front side of the water circuit bracket. 242 is disassembled to allow for maintenance of the pump module 1270 on the outside of the main body 1000. After the pump module 1270 is maintained, the pump module 1270 is inserted into the first mounting hole 1245 through the third opening 1242 on the front side of the water circuit bracket, and the valve module 1260 is inserted into the first groove 1241 through the third opening 1242. The whole process does not require damage to the indoor ceiling structure (i.e., this solution allows for maintenance of the pump module 1270 through the window of the grid installed on the ceiling via the third opening 1242). Therefore, this solution can further reduce the need for a dedicated maintenance port for the air handling equipment in the indoor ceiling.

[0051] In some embodiments, such as Figures 9 to 12 As shown, the pump body module 1270 includes: a liquid pump 1271; and a pump bracket 1272. The liquid pump 1271 is disposed on the pump bracket 1272, and the pump bracket 1272 is installed in the first mounting hole 1245. Compared with disassembling and assembling the liquid pump 1271 separately in the first groove 1241, it is easier to disassemble and assemble the pump bracket 1272 in the first groove 1241.

[0052] In one embodiment, such as Figures 9 to 12As shown, the pump bracket 1272 is a groove-shaped component with the groove opening facing upwards. The bottom wall (i.e., lower end wall) of the groove-shaped component has a third mounting hole 1273. The liquid pump 1271 is located inside the groove-shaped component and positioned at the third mounting hole 1273. The upper front part of the groove-shaped component has a first limiting part 1274, and the upper rear part has an upward-protruding protrusion 1275. The upper front part of the wall of the first mounting hole 1245 has a first limiting mating part. The first limiting part 1274 and the first limiting mating part... With the mating parts engaged, the second screw passes through the protrusion 1275 from front to back and is screwed onto the rear side wall of the first groove 1241. Thus, by removing the second screw through the third opening 1242 (the first limiting part 1274 and the first limiting mating part alone cannot confine the grooved component within the first mounting hole 1245), the grooved component can be moved upwards from the first mounting hole 1245 into the first groove 1241, and then disassembled from the third opening 1242 towards the front of the water channel bracket. The liquid pump 1271 is a water pump.

[0053] In some examples, such as Figures 9 to 12 As shown, the front part of the lower sidewall of the first groove 1241 is provided with a second mounting hole 1243 that runs vertically through it (i.e., the second mounting hole 1243 is located in front of the first mounting hole 1245); the water system mechanism 1210 also includes a water level detection module, which is configured to be inserted into the second mounting hole 1243 through the third opening 1242 and the first groove 1241 on the front side of the first sidewall 1240. The water level detection module is also configured to be detached from the second mounting hole 1243 through the first groove 1241 and the third opening 1242 to the front side of the first sidewall 1240. In this way, when the water level detection module is abnormal, the grille set at the first air vent 1211 on the indoor ceiling can be removed, and the water system mechanism can be detached from the second mounting hole 1243 through the first groove 1241 and the third opening 1242. The valve body module 1260 and the water level detection module in the first groove 1241 are disassembled sequentially from the third opening 1242, allowing the water level detection module to be inspected from the outside of the main body 1000. After the water level detection module is inspected, the water level detection module is then installed into the second mounting hole 1243 from the third opening 1242 on the front side of the water circuit bracket, and the valve body module 1260 is installed into the first groove 1241 from the third opening 1242. The whole process does not require damage to the indoor ceiling structure (i.e., this solution allows the water level detection module to be inspected through the window of the grid installed on the ceiling via the third opening 1242). Therefore, this solution can further reduce the need for a dedicated maintenance port for the air handling equipment in the indoor ceiling.

[0054] In some embodiments, such as Figures 9 to 12As shown, a mounting wall 1244 is provided inside the second mounting hole 1243. The mounting wall 1244 has a through-hole. The area outside the mounting wall 1244 and the through-hole in the second mounting hole 1243 forms a passage gap. The water level detection module includes a water level detection element 1280. A stud 1281 is provided on the upper part of the water level detection element 1280. The water level detection element 1280 passes through the second mounting hole 1243 from above the mounting wall 1244 through the passage gap and is placed below the mounting wall 1244. The stud 1281 passes through the through-hole in the vertical direction. A nut 1282 is screwed onto the stud 1281 from top to bottom, so that the water level detection element 1280 is fixed to the mounting wall 1244. Thus, by removing the nut 1282 from the third opening 1242, the water level detection element 1280 can be disassembled from the third opening 1242 towards the front of the water circuit bracket. This solution is simple to operate. The water level detection element 1280 is a float switch.

[0055] In some examples, such as Figure 1 , Figure 2 and Figure 7 As shown, the waterway mechanism 1210 further includes a first folded cover plate 1290. The first folded cover plate 1290 includes a first plate segment erected in the front-to-back direction and a second plate segment erected in the left-to-right direction. The first plate segment is located behind and connected to the second plate segment. The first plate segment covers the opening of the first groove 1241, and the second plate segment covers the third opening 1242, thereby sealing the opening of the first groove 1241 and the third opening 1242 with the first folded cover plate 1290. The rear end of the first plate segment is inserted rearward into the rear sidewall of the first groove 1241, and a fourth screw passes through the second plate segment from front to back and is screwed onto the front end face of the first sidewall 1240, thus fixing the first folded cover plate 1290 to the first sidewall 1240. When it is necessary to repair at least one of the water pump, control valve 1261 and water level detection component 1280, the fourth screw is removed from the front side of the water circuit bracket, and the first folded cover plate 1290 can be removed from the front side of the water circuit bracket, so that the groove of the first groove 1241 and the third opening 1242 are exposed. At this time, the pump body module 1270, valve body module 1260 and water level detection module can be disassembled and assembled from the third opening 1242.

[0056] In some examples, such as Figure 11 and Figure 12As shown, the top wall 1230 is provided with a connected spray nozzle 1212 and a first water inlet. The water circuit mechanism 1210 also includes a tee 1310. The outlet of the control valve 1261 is connected to the first interface of the tee 1310, and the first water inlet is connected to the second interface of the tee 1310. The water receiving tray 1220 is provided with a water storage area 1222 and a drainage area 1223. The support boss 1221 is located in the water storage area 1222, and the drainage area 1223 is located on the rear side of the water storage area 1222. The third interface of the tee 1310 is connected to the water storage area 1222 through a water pipe. The right rear part of the first side wall 1240 is provided with a second water inlet. The inlet of the control valve 1261 is connected to the outlet of the second water inlet through a water pipe, and the inlet of the second water inlet is connected to a tap water source.

[0057] Among them, control valve 1261 includes one or more valves arranged in series (such as...). Figure 9 and Figure 11 As shown, control valve 1261 includes two valves connected in series, and tee 1310 is located downstream of the downstream control valve 1261. Figure 12 As shown, the water pumps include a circulating water pump and a drain water pump. Two third mounting holes 1273 are included, with the circulating water pump and drain water pump installed one-to-one at each of the two third mounting holes 1273. The inlet of the circulating water pump is connected to the water storage area 1222, and the outlet of the circulating water pump is also connected to the first water inlet via a water pipe (the circulating water pump is used to circulate and spray water from the water storage area 1222 onto the wet membrane assembly 300). The inlet of the drain water pump is connected to the water storage area 1222, and the outlet of the drain water pump is connected to the drain area 1223 via a water pipe (the drain water pump is used to drain water from the water storage area 1222 to the drain area 1223). The bottom of the drain area 1223 has a drain outlet for draining water to the outside. Two float switches are included, located within the water storage area 1222, for correspondingly detecting the lowest and highest water levels in the water storage area 1222 (e.g., ...). Figure 12 (As shown).

[0058] When the water level in the water storage area 1222 reaches the minimum water level, the control valve 1261 opens, and the second interface of the tee 1310 supplies water from the first water inlet to the spray nozzle 1212. During this process, the outlet of the circulating water pump also supplies water from the first water inlet to the spray nozzle 1212 through the water pipe to ensure that the spray volume of the spray nozzle 1212 is sufficient. The third interface of the tee 1310 replenishes water to the water storage area 1222 through the water pipe.

[0059] When the water level in the water storage area 1222 reaches the highest water level, the control valve 1261 closes, and the outlet of the circulating water pump continues to supply water from the first water inlet to the spray outlet 1212 through the water pipe.

[0060] In some examples, such as Figure 2 , Figure 6 , Figure 13 and Figure 14 As shown, the air handling equipment also includes an electrical control box 400, which includes a base box 410, a second folded cover plate 420, and a control plate 430. The base box 410 is located on the side of the second side wall 1250 facing away from the first side wall 1240, and the opening of the base box 410 faces away from the side where the first side wall 1240 is located. The front side of the base box 410 is provided with a fourth opening 411. The control plate 430 is configured to be inserted into the base box 410 through the fourth opening 411 on the front side of the second side wall 1250. The control plate 430 is also configured to be detached from the base box 410 through the fourth opening 411 on the front side of the second side wall 1250. The second folded cover plate 420 is installed on the base box 410 and covers the opening of the base box 410 and the fourth opening 411. The fourth folded cover plate is configured to be detached and installed on the front side of the second side wall 1250.

[0061] When maintenance is required on the control panel 430, the grille installed at the first air vent 1211 on the indoor ceiling is removed, and then the second folded cover plate 420 and the control panel 430 are removed in sequence on the front side of the second side wall 1250 to perform maintenance on the control panel 430. After the maintenance on the control panel 430 is completed, the control panel 430 and the second folded cover plate 420 are reinstalled in sequence on the front side of the second side wall 1250. This solution can further reduce the need to open a special maintenance port for the air handling equipment in the indoor ceiling.

[0062] In one embodiment, such as Figure 13 and Figure 14 As shown, the rear part of the second folded cover plate 420 is inserted into the rear part of the bottom box 410, and the fifth screw passes through the front part of the second folded cover plate 420 from front to back and is screwed into the front part of the bottom box 410, so that the second folded cover plate 420 can be installed and removed from the front side of the second side wall 1250.

[0063] In one embodiment, such as Figure 13 and Figure 14 As shown, the base box 410 has a mounting bracket 440 inside. The mounting bracket 440 has a first locking position (not shown in the figure) on its rear side, a second locking position (not shown in the figure) on its front side, and a release mechanism (not shown in the figure). The first locking position engages with the rear end of the control board 430, positioning the rear end of the control board 430. The second locking position engages with the front end of the control board 430, positioning the front end of the control board 430, thus fixing the control board 430 to the side of the mounting bracket 440. When it is necessary to remove the control board 430, the second locking position is released through the fourth opening 411 by pressing the release mechanism, causing the front end of the control board 430 to disengage (the first locking position alone cannot fix the control board 430 to the mounting bracket 440). The control board 430 can then be removed from the fourth opening 411. This solution is simple to operate and easy to implement.

[0064] In one embodiment, the air handling device is a humidifier.

[0065] In another embodiment, the air handling equipment is a purifier or a fresh air unit. Compared with a humidifier, a purifier or fresh air unit only requires the removal of the wet film assembly 300 and the spray assembly 1200, and then a removable filter is installed at the first air outlet 1211. The maintenance method of the fan assembly 200 of the purifier or fresh air unit remains unchanged, and the maintenance method of the control board 430 of the purifier or fresh air unit also remains unchanged.

[0066] In summary, the technical solution provided in this application embodiment allows the fan assembly to be installed into the receiving cavity from the outside of the main body via the first air inlet, and also allows it to be disassembled from the receiving cavity to the outside of the main body via the first air inlet. Thus, when the fan assembly malfunctions, the grille located at the first air inlet on the indoor ceiling can be removed, and the fan assembly can be disassembled from the first air inlet from the outside of the main body, enabling maintenance of the fan assembly from the outside of the main body. After maintenance, the fan assembly can be reinstalled into the receiving cavity from the first air inlet from the outside of the main body. The entire process does not require damage to the indoor ceiling structure; therefore, this solution reduces the need for a dedicated maintenance access port for the air handling equipment in the indoor ceiling.
