[0053] Please see Figures 1 to 3 This invention provides an embodiment of an air handling device 100, which can be used independently for air handling or installed on the air conditioning unit 310 of a floor-standing air conditioner 300. The air handling device 100 can increase the diversity of air outlet areas, thereby expanding its air outlet range and improving the airflow effect during use. The air handling device 100 will be described in detail below.

[0054] Please see Figures 3 to 5 In one embodiment of the air handling apparatus of the present invention, the air handling apparatus 100 includes a housing 110 and a fan module 200 (see [reference needed]). Figure 10 The housing 110 has a first air outlet 102 on its front side and a second air outlet 103 on its top surface. The fan module 200 is installed inside the housing 110, and the air outlet of the fan module 200 is connected to both the second air outlet 103 and the first air outlet 102.

[0055] Specifically, the housing 110 has a top surface, a front side surface, a back surface, and two side surfaces connecting the front side surface and the back surface. The housing 110 has an air inlet 101 on its back surface or side surface, which communicates with the inlet end of the fan module 200. When the air handling unit 100 is operating, air can enter the interior of the fan module 200 through the air inlet 101, and then flow through the air outlet duct 201 of the fan module 200 to the first air outlet 102 and the second air outlet 103 before being blown out.

[0056] Regarding the first air outlet 102, it can be located at the middle or upper part of the front side of the housing 110 along the height direction; the first air outlet 102 can be configured as any shape among square, circular, and elliptical openings, without specific limitation. Regarding the second air outlet 103, it can be located at the middle or front part of the top surface of the housing 110 along the front-rear direction; the second air outlet 103 can also be configured as any shape among square, circular, and elliptical openings, without specific limitation. In this embodiment, both the first air outlet 102 and the second air outlet 103 are square in shape and extend along the width direction (i.e., the left-right direction) of the air handling device 100.

[0057] The technical solution of this invention provides a first air outlet 102 on the front side of the housing 110 and a second air outlet 103 on the top surface of the housing 110. Both the second air outlet 103 and the first air outlet 102 are connected to the air outlet end of the internal fan module 200. When the air handling device 100 is operating, the fan module 200 draws air in from its inlet and delivers it to its outlet. This air is split into two airflows at the outlet end: one airflow blows upwards from the first air outlet 102 on the top surface of the housing 110, and the other airflow blows forward from the second air outlet 103 on the front side of the housing 110. This allows the air handling device 100 to have at least two air outlet areas, effectively expanding the air outlet range of the air handling device 100 and improving the airflow effect during use.

[0058] Furthermore, for some conventional air handling units 100 with two air outlets, these conventional air handling units 100 typically require a separate fan module 200 for each air outlet, which increases the number of fan modules 200, their cost, and the space occupied by the unit. However, for the air handling unit 100 of the present invention, its first air outlet 102 and second air outlet 103 share the same fan module 200 (i.e., share the same impeller 220 of the same fan module 200), thus reducing the use of fan modules 200, thereby reducing the cost of using fan modules 200 and the space occupied by the unit.

[0059] Please see Figure 4 In one embodiment, the air handling device 100 further includes a first baffle 120, which is movably disposed at the first air outlet 102 for opening and closing the first air outlet 102; and / or, the air handling device 100 further includes a second baffle 130, which is movably disposed at the second air outlet 103 for opening and closing the second air outlet 103.

[0060] Specifically, a first baffle plate 120 is provided at the first air outlet 102, which is movable relative to the housing 110 to open and close the first air outlet 102; and a second baffle plate 130 is provided at the second air outlet 103, which is movable relative to the housing 110 to open and close the second air outlet 103. This design allows the air handling unit 100 to have at least three air outlet modes: front air outlet mode, top air outlet mode, and bidirectional air outlet mode. These three air outlet modes are described below.

[0061] When the air handling unit 100 is operating in top-outlet mode, the first baffle 120 closes the first air outlet 102, while the second baffle 130 opens the second air outlet 103, allowing the air handling unit 100 to blow the treated air upwards from the second air outlet 103.

[0062] When the air handling unit 100 is operating in the front air outlet mode, the first baffle 120 opens the first air outlet 102 while the second baffle 130 closes the second air outlet 103, and the air handling unit 100 can blow the processed air forward from the first air outlet 102.

[0063] When the air handling unit 100 operates in bidirectional airflow mode, the first baffle 120 opens the second air outlet 103, and the second baffle 130 also opens the second air outlet 103. The air handling unit 100 can divide the treated air into two airflows, which are blown out from the first air outlet 102 and the second air outlet 103 respectively, achieving simultaneous airflow from the top and front. In this mode, the airflow blown out from the air outlet duct 201 of the fan module 200 is separated into two airflows, which are blown out from the first air outlet 102 and the second air outlet 103 simultaneously. This enables close-range, wide-area air delivery, thereby preventing the airflow from concentrating and blowing forward from the first air outlet 102 towards the user, and thus preventing cold air from blowing directly onto the user's abdomen.

[0064] Regarding the movable installation method of the first wind deflector 120 and the second wind deflector 130, there are various design options. Taking the first wind deflector 120 as an example, the first wind deflector 120 can be rotatably mounted on the housing 110 so that the first air outlet 102 can be opened and closed by rotating the first wind deflector 120; or, the first wind deflector 120 can be slidably mounted on the housing 110 so that the first air outlet 102 can be opened and closed by sliding the first wind deflector 120. Similarly, the second wind deflector 130 can also be rotatably mounted on the housing 110 so that the second air outlet 103 can be opened and closed by rotating the second wind deflector 130; or, the second wind deflector 130 can be slidably mounted on the housing 110 so that the second air outlet 103 can be opened and closed by sliding the second wind deflector 130.

[0065] Please see Figure 5In one embodiment, the fan module 200 includes a duct housing 210 and a fan wheel 220 disposed within the duct housing 210. The duct housing 210 includes a volute 211 and a volute tongue 212, forming an air outlet duct 201 between the volute 211 and the volute tongue 212, with an air outlet at the end of the air outlet duct 201. The fan wheel 220 is a centrifugal fan wheel; the air outlet duct 201 formed between the volute 211 and the volute tongue 212 is a centrifugal duct. That is, the fan module 200 blows airflow from the air outlet duct 201 through the same fan wheel 220. When this airflow reaches the air outlet of the air outlet duct 201, it can be blown out from either the first air outlet 102 or the second air outlet 103, or it can be split into two streams of airflow that are blown out from either the first air outlet 102 or the second air outlet 103 respectively.

[0066] Furthermore, the volute tongue 212 extends obliquely upward from the front side of the impeller 220 to the lower side of the first air outlet 102. This avoids the formation of a gap between the volute tongue 212 and the first air outlet 102 that could allow airflow leakage. The volute tongue 212 can be used to directly guide the airflow attached to the volute tongue 212 in the air outlet duct 201 to the first air outlet 102, reducing airflow resistance and preventing airflow leakage.

[0067] Furthermore, the volute 211 can extend obliquely upwards and forwards from the rear side of the impeller 220 to the rear side of the second air outlet 103. This avoids the formation of a gap between the volute 211 and the second air outlet 103 that could allow airflow leakage. The volute 211 can be used to directly guide the airflow attached to the wall of the air outlet duct 201 to the second air outlet 103, reducing airflow resistance and the occurrence of airflow leakage.

[0068] Please see Figure 5 and Figure 6 , Figure 6 In this design, α represents the angle between the extension direction of the volute 211 and the top surface of the housing 110, and β represents the angle between the extension direction of the volute tongue 212 and the top surface of the housing 110. Optionally, the angle between the extension direction of the volute 211 and the top surface of the housing 110 is greater than the angle between the extension direction of the volute tongue 212 and the top surface of the housing 110, i.e., α > β. With this design, the volute tongue 212 guides the airflow to be blown forward at an angle from the first air outlet 102, while the volute 211 guides the airflow to be blown forward and upward at an angle from the second air outlet 103. Furthermore, the airflow deflected by the volute 211 has a larger deflection angle, which helps to increase the airflow volume diffused to the area in front of the air handling unit 100, making the area in front of the air handling unit 100 more comfortable.

[0069] In addition, the airflows from the first air outlet 102 and the second air outlet 103 both have an upward-sloping velocity component, which ensures that both airflows avoid the user's abdomen and do not blow directly onto the user's abdomen because the overall height of the air handling unit 100 is close to the user's abdomen height, effectively preventing the airflow from the air handling unit 100 from causing discomfort to the user's abdomen.

[0070] Regarding the angle formed between the extension direction of the volute 211 and the top surface of the shell 110, optionally, the angle is greater than or equal to 30° and less than or equal to 60°, i.e., 30°≤α≤60°. α can be, but is not limited to, 32°, 35°, 40°, 45°, 48°, 50°, 55°, 58°, etc. Specifically, guided by the volute 211, the airflow blown from the second air outlet 103 has a horizontal component velocity in the horizontal direction and forward, and a longitudinal component velocity in the longitudinal direction and upward. By limiting α within this range, the horizontal velocity and longitudinal velocity of the airflow from the second air outlet 103 can be the same or not significantly different, thereby resulting in the airflow being uniformly diffused and blown out from the second air outlet 103 forward and upward.

[0071] Regarding the angle between the extension direction of the volute tongue 212 and the top surface of the housing 110, optionally, the angle between the extension direction of the volute tongue 212 and the top surface of the housing 110 is greater than or equal to 8° and less than or equal to 30°, i.e., 8°≤β≤30°. β can be, but is not limited to, 9°, 12°, 15°, 18°, 20°, 25°, 28°, etc. Specifically, guided by the volute tongue 212, the airflow blown from the first air outlet 102 also has a horizontal component velocity in the horizontal direction and forward direction, and a longitudinal component velocity in the longitudinal direction and upward direction. By limiting β within this range, the horizontal wind speed of the airflow from the first air outlet 102 can be made to be greater than the longitudinal component velocity, thereby causing the airflow blown from the first air outlet 102 to be slightly inclined upward and diffused, but not entirely blown to the upper area, ensuring that sufficient air volume reaches the front area and ensuring better comfort in the front area of ​​the air handling device 100.

[0072] Please see Figure 7 , Figure 8 and Figure 10 In one embodiment, in order to facilitate better connection between the first air outlet 102 and the second air outlet 103 on the housing 110 and the air outlet end of the air outlet duct 201 of the fan module 200, the air duct housing 210 of the fan module 200 may optionally include a separator 213 disposed between the volute housing 211 and the volute tongue 212; the separator 213 divides the air outlet end of the air outlet duct 201 into a front air outlet end 201a that connects with the first air outlet 102 and an upper air outlet end 201b that connects with the second air outlet 103.

[0073] Specifically, the air outlet duct 201 formed by the volute 211 and the volute tongue 212 is flared; the separator 213 is located in the air outlet area between the volute 211 and the volute tongue 212. The separator 213 is elongated and extends in the left and right directions along the air handling device 100. The two ends of the separator 213 are respectively connected to the side plates of the air duct housing 210 located on the left and right sides of the air outlet duct 201, so that the separator 213 divides the air outlet end of the air outlet duct 201 into the upper air outlet end 201b and the front air outlet end 201a.

[0074] The upper air outlet 201b is located between the end of the volute 211 and the separator 213, and is connected to the second air outlet 103 of the housing 110; the front air outlet 201a is located between the end of the volute tongue 212 and the separator 213, and is connected to the first air outlet 102 of the housing 110. Thus, the airflow blown from the air outlet duct 201 of the fan module 200 is smoothly divided into two airflows at the air outlet end of the air outlet duct 201 by the separator 213. One airflow flows from the front air outlet 201a to the first air outlet 102, while the other airflow flows through the upper air outlet 201b to the second air outlet 103.

[0075] Please see Figures 8 to 10 For the separator 213, the separator 213 has an air outlet wall 213a facing the volute 211, and the air outlet wall 213a is inclined in the same direction as the volute 211. That is, the air outlet wall 213a is opposite to the volute 211 and inclined in the same direction. In this way, when the airflow blown out of the air outlet duct 201 is separated by the separator 213, the airflow that is separated to the upper air outlet 201b will be blown out forward and upward with the cooperation of the volute 211 and the air outlet wall 213a of the separator 213, which effectively reduces the wind resistance in the process of the airflow being diverted to the second air outlet 103, making the airflow smoother. It is worth mentioning that the partition 213 also has a bottom wall facing the volute tongue 212. Here, the bottom wall of the partition 213 is set horizontally, so that the bottom wall of the partition 213 can blow the airflow from the front air outlet 201a to the first air outlet 102 forward, so as to avoid the airflow being too concentrated upward.

[0076] Please see Figures 10 to 12 The separator 213 can be integrally formed with the side plates of the duct housing 210, or it can be separately configured. Specifically, the duct housing 210 has side plates located on the left and right sides of the air outlet duct 201; the separator 213 is an independently formed component, and the separator 213 is detachably connected to the side plates of the duct housing 210. Slots 203 are provided on the two side plates of the duct housing 210, and the slots 203 are wedge-shaped; the two ends of the separator 213 are respectively inserted into the two slots 203 and fixed to the side plates with screws.

[0077] Please see Figure 8 , Figure 10 and Figure 13 Given that the air outlet of the fan module 200 is divided into a front air outlet 201a and an upper air outlet 201b by the separator 213, in order to allow the airflow blown from the air outlet duct 201 to be smoothly diverted to the front air outlet 201a, the duct housing 210 may optionally include a first air guide wall 214 disposed on both sides of the end of the volute tongue 212, at least one of the first air guide walls 214 being inclined from back to front in a direction away from the other first air guide wall 214.

[0078] Specifically, the two first air guide walls 214 of the air duct housing 210 are arranged opposite each other along the left-right direction of the air handling device 100. The first air guide wall 214 on the left is inclined from back to front and to the left, while the first air guide wall 214 on the right is inclined from front to back and to the right, thus forming a front flared section between the two first air guide walls 214 corresponding to the front air outlet 201a. This arrangement allows the airflow from the air outlet duct 201 to be guided to the front air outlet 201a via the front flared section between the two first air guide walls 214, and then blown forward and upward from the first air outlet 102. Furthermore, guided by the two first air guide walls 214, the airflow can diffuse from both sides of the first air outlet 102, thereby increasing the airflow range on both sides; and it also prevents the airflow from swirling or recirculating near the front air outlet 201a.

[0079] Please see Figure 8 , Figure 10 and Figure 14 In one embodiment, in order to allow the airflow blown out from the air outlet duct 201 to be smoothly diverted to the upper air outlet 201b, the duct housing 210 further includes second air guide walls 215 disposed on both sides of the end of the volute housing 211, at least one of the second air guide walls 215 being inclined from bottom to top in a direction away from the other second air guide wall 215.

[0080] Specifically, the two second guide walls 215 of the air duct housing 210 are arranged opposite each other along the left-right direction of the air handling unit 100. The second guide wall 215 on the left is inclined upwards towards the left, while the second guide wall 215 on the right is inclined upwards towards the right, thus forming an upwardly flared section between the two second guide walls 215 corresponding to the upper air outlet 201b. This arrangement allows the airflow from the air outlet duct 201 to be guided to the upper air outlet 201b via the upwardly flared section between the two second guide walls 215, and then blown forward from the second air outlet 103. Furthermore, guided by the two second guide walls 215, the airflow can diffuse outwards from both sides of the second air outlet 103, increasing the airflow range on both sides; and it also prevents the airflow from swirling or recirculating near the upper air outlet 201b.

[0081] Furthermore, the first guide wall 214 and the second guide wall 215, located on the same side of the duct shell 210, intersect to form a boundary line 202. The boundary line 202 is on the same plane as the outlet wall 213a of the separator 213, and the extension direction of the boundary line 202 is consistent with the inclination direction of the outlet wall 213a. This arrangement allows part of the airflow exiting from the end of the second guide wall 215 to smoothly transition to the outlet wall 213a of the separator 213, and then be exited by the outlet wall 213a, reducing the resistance to airflow.

[0082] Please see Figure 7 and Figure 8 In one embodiment, considering that the width of the air outlet end of the fan module 200 along the front-to-back direction is relatively limited, if the first air outlet 102 and the second air outlet 103 are far apart, it is not easy for the air outlet end of the fan module 200 to directly connect with the first air outlet 102 and the second air outlet 103. In view of this situation, optionally, the first air outlet 102 is located at the upper end of the front side of the housing 110, and the second air outlet 103 is located at the front end of the top surface of the housing 110, so that the second air outlet 103 and the first air outlet 102 are close to each other.

[0083] Specifically, the distance between the ends of the volute 211 and the volute tongue 212 of the fan module 200 defines the width of its air outlet. In this embodiment, since the first air outlet 102 is located at the upper end of the front side of the housing 110, and the second air outlet 103 is located at the front end of the top surface of the housing 110, the distance between the second air outlet 103 and the first air outlet 102 in the front-rear direction is small. This allows the air outlet of the fan module 200 to directly connect with these two air outlets without needing to increase the width of the air outlet of the fan module 200, thus preventing the fan module 200 from becoming too large. For example, the distance between the rear edge of the second air outlet 103 and the front side of the top surface of the housing 110 is less than or equal to 2 / 3 of the distance between the front side and the rear side of the top surface of the housing 110. This ensures that the second air outlet 103 is located at the front end of the top surface of the housing 110 and close to the front side of the top surface.

[0084] Furthermore, considering that the overall height of the air handling unit 100 is typically designed to be relatively small, the airflow blowing from the first air outlet 102 of the air handling unit 100 may be directed directly at the user's abdomen. When the airflow from the first air outlet 102 is cold air, the cold air blowing directly onto the user's abdomen can easily cause discomfort such as abdominal pain or a cold. Therefore, to reduce the occurrence of this situation, optionally, the distance between the lower side of the first air outlet 102 and the lowest point of the housing 110 is not less than 500mm. This distance can be, but is not limited to, 510mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm, etc. This ensures that the airflow blowing from the first air outlet 102 is directed towards a position higher than the user's abdomen, thus avoiding cold air blowing directly onto the user's abdomen. The specific configuration can be reasonably adjusted based on the height of the air handling unit 100, and is not specifically limited here.

[0085] In one embodiment, the air outlet effect at the location of the fan module 200 within the air handling unit 100 is experimentally simulated, and the results obtained from the simulation are as follows: Figure 20 The simulation result shown is illustrated below. Figure 20 It can be seen that the airflow from the upper outlet 201b of the fan module 200 has a larger velocity and flow rate, while the airflow from the front outlet 201a of the fan module 200 has a relatively smaller velocity and flow rate. Therefore, optionally, the outlet surface area of ​​the second outlet 103 can be designed to be larger than that of the first outlet 102, so that more airflow from the upper outlet 201b of the fan module 200 can be blown out from the second outlet 103, avoiding airflow obstruction at the outlet and the occurrence of vortices or backflow.

[0086] Please see Figure 5 , Figure 10 and Figure 11Based on any of the above embodiments, the air handling device 100 further includes a first air guide assembly 230, which is disposed at the first air outlet 102 to adjust the air outlet direction of the first air outlet 102. The first air guide assembly 230 can be configured to guide air left and right or to guide air up and down.

[0087] Specifically, the first air guide assembly 230 includes a plurality of first air guide vanes 231, a first connecting rod 232 connecting the plurality of first air guide vanes 231, and a crank 233 connected to the first connecting rod 232; wherein, the plurality of first air guide vanes 231 are arranged at intervals at the first air outlet 102; the first connecting rod 232 is rotatably connected to the plurality of first air guide vanes 231, so that when the crank 233 is driven to swing, the crank 233 will drive the first connecting rod 232 to move along its length direction, thereby causing the first connecting rod 232 to drive the plurality of first air guide vanes 231 to rotate in the same direction, thereby guiding the airflow from the first air outlet 102 to the corresponding position.

[0088] It is understandable that multiple first guide vanes 231 can be arranged at intervals in the left and right direction to guide the wind in the left and right directions; of course, multiple first guide vanes 231 can also be arranged at intervals in the up and down direction to guide the wind in the up and down direction.

[0089] Furthermore, the air handling device 100 also includes a first motor 250 for driving the first air guide assembly 230 to rotate. Specifically, the first motor 250 is connected to the crank 233 of the first air guide assembly 230 to drive the crank 233 to rotate, so that the crank 233 drives the first connecting rod 232 to move along its length direction, and then the first connecting rod 232 drives the plurality of first air guide vanes 231 to rotate in the same direction, thereby realizing air guidance.

[0090] To avoid the first motor 250 occupying the air outlet duct 201, optionally, a first cavity 104 is formed between the back of the volute tongue 212 of the duct housing 210 and the front side of the housing 110 for the installation of the first motor 250. By placing the first motor 250 within this first cavity 104 and connecting and fixing it to the back of the volute tongue 212, the first motor 250 can avoid occupying space in the air outlet duct 201, thereby allowing for smoother airflow within the air outlet duct 201. Of course, the installation position of the first motor 250 is not limited to this; the first motor 250 can also be installed in other locations on the duct housing 210.

[0091] Please see Figure 5 , Figure 10 and Figure 11Based on any of the above embodiments, the air handling device 100 further includes a second air guide assembly 240, which is disposed at the second air outlet 103 to adjust the air outlet direction of the second air outlet 103. The second air guide assembly 240 can be configured to guide air left and right or to guide air forward and backward.

[0092] Specifically, the second air guide assembly 240 includes a plurality of second air guide vanes 241 and a second connecting rod 242 connecting the plurality of second air guide vanes 241; wherein, the plurality of second air guide vanes 241 are arranged at intervals at the second air outlet 103; the second connecting rod 242 is rotatably connected to the plurality of second air guide vanes 241, thereby driving any one of the second air guide vanes 241 to rotate, which in turn drives the other second air guide vanes 241 to rotate in the same direction through the second connecting rod 242, thereby guiding the airflow from the second air outlet 103 to the corresponding position.

[0093] It is understood that multiple second guide vanes 241 can be arranged at intervals in the left-right direction to achieve left-right airflow guidance; of course, multiple second guide vanes 241 can also be arranged at intervals in the front-back direction to achieve front-back airflow guidance. In this embodiment, multiple second guide vanes 241 extend in a long strip shape in the front-back direction and are arranged at intervals in the left-right direction; the two ends of the second guide vanes 241 are rotatably connected to the volute 211 and the separator 213 of the air duct shell 210, respectively.

[0094] Specifically, the end of the volute 211 is provided with a first shaft hole, and the air outlet wall 213a of the partition 213 is provided with a second shaft hole (see...). Figure 18 and Figure 19 The second guide vane 241 has a rotating shaft at both ends, and the rotating shafts at both ends of the second guide vane 241 are rotatably connected to the first shaft hole of the volute 211 and the second shaft hole on the separator 213, respectively.

[0095] Furthermore, the air handling unit 100 also includes a second motor 260 for driving the second air guide assembly 240 to rotate. Specifically, the second motor 260 is rotatably connected to the shaft of one of the second air guide vanes 241 to drive the second air guide vane 241 to rotate. The rotation of the second air guide vane 241 drives the other second air guide vanes 241 to rotate in the same direction through the second connecting rod 242, thereby realizing air guidance.

[0096] To avoid the second motor 260 occupying the air outlet duct 201, optionally, a second cavity 105 is formed between the back of the volute tongue 212 of the duct housing 210 and the front side of the housing 110 for the installation of the second motor 260. By placing the second motor 260 within this second cavity 105 and connecting and fixing it to the back of the volute tongue 212, the second motor 260 can avoid occupying space in the air outlet duct 201, thereby allowing for smoother airflow within the air outlet duct 201. Of course, the installation position of the second motor 260 is not limited to this; the second motor 260 can also be installed in other locations on the duct housing 210.

[0097] Please see Figure 5 , Figure 13 and Figure 14 Based on any of the above embodiments, the air handling device 100 further includes a first protective net 281, which is disposed within the air outlet duct 201 and faces the front air outlet end 201a of the fan module 200. The air handling device 100 also includes a second protective net 282, which is disposed within the air outlet duct 201 and faces the upper air outlet end 201b of the fan module 200.

[0098] Specifically, the mesh surfaces of the first protective net 281 and the second protective net 282 are arranged at an angle. The upper end of the first protective net 281 and the front end of the second protective net 282 are connected to form a whole. It is worth mentioning that the first protective net 281 and the second protective net 282 can be formed separately and then connected together, or they can be formed as a single piece; there is no limitation here. Specifically, in this embodiment, the first protective net 281 and the second protective net 282 are formed as a single piece.

[0099] Please see Figures 15 to 17 Based on any of the above embodiments, the air handling device 100 further includes a water receiving tray 140 disposed below the fan module 200; wherein, the bottom of the fan module 200 is provided with a fixing ear 271 and a screw thread 272, the fixing ear 271 is inserted and positioned with the water receiving tray 140, and the screw thread 272 is connected and fixed to the water receiving tray 140.

[0100] Specifically, the fan module 200 has a support base 270 protruding from the bottom of the air duct shell 210. The support base 270 has multiple support plates arranged in a square shape. A fixing lug 271 protrudes downward from the outside of the support plate, and a screw post 272 protrudes from the inside of the support plate. The water receiving tray 140 is provided with a fixing hole 141 corresponding to the screw post 272.

[0101] During assembly, first insert the multiple fixing ears 271 on the support base 270 of the fan module 200 into the water receiving tray 140 to position the fan module 200 on the water receiving tray 140; then, use screws to pass through the fixing holes 141 of the water receiving tray 140 and the threaded posts 272 of the support base 270 to connect and fix the two. Of course, the fixing ears 271 can also be further fixed to the water receiving tray 140 with screws to strengthen the connection between the fan module 200 and the water receiving tray 140. After the fan module 200 and the water receiving tray 140 are connected and fixed into a whole structure, this whole structure can be installed into the housing 110 of the air handling unit 100.

[0102] Please see Figures 1 to 3 The present invention also provides a floor-standing air conditioner 300, which includes an air conditioning unit 310 and an air handling unit 100. The air handling unit 100 is detachably connected to the air conditioning unit 310 and can operate independently of the air conditioning unit 310.
