[0048] In the technical solution of the present invention, the partition includes a first plate, a second plate, and a third plate. The first plate is connected to the second plate and the third plate on either side. Because the second plate and the third plate can be located at different positions along a first direction within the housing, when the spacing between the air supply assembly and the heat exchange assembly changes, the spacing between the second and third plates in the partition can be adjusted along the first direction to accommodate the change in spacing between the air supply assembly and the heat exchange assembly. For example, when the distance between the air supply assembly and the heat exchange assembly increases, the second plate is positioned further away from the heat exchange assembly; when the distance between the air supply assembly and the heat exchange assembly decreases, the second plate is positioned closer to the heat exchange assembly. In this solution, regardless of how the spacing between the air supply assembly and the heat exchange assembly changes, the opening in the second plate can accommodate the change in position of the air supply assembly. Therefore, there is no need to change the shape of the air supply assembly or alter the mating relationship between the partition and other components within the air handling unit. For example, while the partition in the original product mated with the water tray, the partition in the modified product can still maintain the same mating relationship with the water tray. In other words, when the distance between the air supply component and the heat exchange component changes, it is only necessary to change the shape of the partition to adapt, and the cost of changing the internal structure layout of the air handling unit is reduced.

[0087] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0089] The air conditioner includes a housing, a partition, an air supply assembly, and a heat exchange assembly within the housing. The partition divides the interior of the housing into two chambers, with the air supply assembly and heat exchange assembly located in the two chambers, respectively. The partition has an opening, and the air supply assembly is positioned on the partition. The air supply assembly directs airflow through the opening to the heat exchange assembly.

[0090] During product upgrades, for example, in an actual scenario, the electronic control box of the old version of the air conditioner is located on the rear side of the air supply assembly (i.e., the side of the air supply assembly facing away from the heat exchange assembly), and the distance between the air supply assembly and the heat exchange assembly is relatively close. In order to facilitate the maintenance of the electronic control box, or to reduce the impact of the vibration of the air supply assembly on the electronic control box, it is necessary to move the electronic control box to the side of the air supply assembly (i.e., the side of the air supply assembly parallel to its own rotation axis). At this time, the distance between the air supply assembly and the back plate of the air conditioner shell (the space originally accommodating the electronic control box) is larger, and the air supply assembly can be moved backward (translationally in the direction away from the heat exchange assembly) to reasonably utilize the internal space. When the air supply assembly is moved backward, since the air supply assembly needs to be positioned on the partition and the airflow needs to be directed from the opening of the partition to the second chamber, it is necessary to adjust the external dimensions of the air supply assembly so that the air supply assembly can cooperate well with the partition, and the cost of the modification is relatively high. Alternatively, the partition can be moved backward along with the air supply assembly, but when the partition moves backward, the positioning structure of the partition and the positioning structure that cooperates with the partition need to be adjusted accordingly. For example, when the partition is positioned on the water tray, the external structure of the water tray needs to be adjusted, and the cost of modification is also high.

[0091] In view of this, see Figures 1-17 This embodiment provides a partition 120, which is used for an air handling unit 10. For example, this embodiment uses an air conditioner as an example for description. The air handling unit 10 includes a housing 110, an air supply assembly 200, and a heat exchange assembly 300.

[0092] See also Figure 1-Figure 4 ,as well as Figure 7 as well as Figure 9 The housing 110 defines an internal chamber, and the partition 120, the air supply assembly 200, and the heat exchange assembly 300 are all disposed in the internal chamber of the housing 110. The partition 120 separates the internal chamber of the housing 110 into a first chamber 115 and a second chamber 116. The air supply assembly 200 is disposed in the first chamber 115, and the heat exchange assembly 300 is disposed in the second chamber 116. The partition 120 also has an opening 1222 that connects the first chamber 115 and the second chamber 116. For ease of description, see Figure 4 , hereinafter, the direction from the first chamber 115 to the second chamber 116 is defined as a first direction X.

[0093] See also Figure 1-Figure 4The housing 110 is provided with an air inlet 118 communicating with the first chamber 115 and an air outlet 119 communicating with the second chamber 116. The air supply assembly 200 is used to direct the airflow within the first chamber 115 into the second chamber 116 through the opening 1222 of the partition 120. When the airflow within the first chamber 115 is directed into the second chamber 116, a negative pressure is generated within the first chamber 115, causing air outside the housing 110 to be introduced into the first chamber 115 through the air inlet 118 communicating with the first chamber 115. Simultaneously, a positive pressure is generated within the second chamber 116, causing the airflow within the second chamber 116 to be discharged out of the housing 110 through the air outlet 119. Before the airflow driven into the second chamber 116 by the air supply assembly 200 is discharged out of the housing 110, it exchanges heat with the heat exchange assembly 300 located in the second chamber 116, thereby regulating the temperature of the air discharged from the housing 110.

[0094] The heat exchange assembly 300 is used to exchange heat with the air flowing through it. Specifically, the heat exchange assembly 300 can absorb heat from the air flowing through it (i.e., the heat exchange assembly 300 is used for cooling) or transfer heat to the air flowing through it (i.e., the heat exchange assembly 300 is used for heating). The partition 120 not only supports the air supply assembly 200, but also prevents energy from escaping from the heat exchange assembly 300 by dividing it into a relatively independent second chamber 116, thereby improving the heat preservation effect of the air conditioner.

[0095] See also Figure 4 as well as Figure 7-Figure 9 The partition 120 includes a first plate 121, a second plate 122, and a third plate 123. The first plate 121 has a first side 1211 and a second side 1212 arranged opposite each other. For ease of description, the direction perpendicular to the first side 1211 and perpendicular to the first direction X is defined as the second direction Y. The second direction Y can be the height direction, width direction, or length direction of the air conditioner. The specific orientation of the second direction Y depends on the actual placement of the air conditioner. In this embodiment, the second direction Y is taken as the height direction of the air conditioner for illustration.

[0096] One side of the second plate 122 is connected to the first side 1211, and the other side extends along the second direction Y. The side of the second plate 122 away from the first side 1211 is the third side 1221, and the third side 1221 is connected to the inner side of the shell 110 (specifically, it can be connected to the lower wall of the upper plate 111 of the shell 110). The second plate 122 is provided with an opening 1222 suitable for connecting the first chamber 115 and the second chamber 116. Figure 4 、 Figure 10 as well as Figure 11In some embodiments, the air supply assembly 200 is fixed to the partition 120, and the air outlet 221 of the air supply assembly 200 extends through the opening 1222 of the second plate 122. This not only facilitates the air supply assembly 200 to direct the air in the first chamber 115 to the second chamber 116, but also improves the sealing performance of the partition 120. In other embodiments, the air supply assembly 200 may not be fixed to the partition 120, and the air outlet 221 of the air supply assembly 200 may be located in the first chamber 115, facing the opening 1222 of the partition 120, thereby facilitating the directing of the airflow in the first chamber 115 to the second chamber 116.

[0097] One side of the third plate 123 is connected to the second side 1212, and the other side extends along the second direction Y. The side of the third plate 123 away from the second side 1212 is the fourth side 1231. The fourth side 1231 and the third side 1221 are located on opposite sides of the partition 120 along the second direction Y. Figure 7 , along the first direction X, the third plate 123 and the second plate 122 are spaced apart. Along the second direction Y, the third plate 123 is at least partially located on the side of the second plate 122 close to the first side 1211. In other words, when viewed along the second direction Y, the first plate 121 and the second plate 122 are staggered. Compared with the structure in which the partition 120 is an entire straight plate, in this embodiment, since the second plate 122 and the third plate 123 can be located at different positions along the first direction X in the shell 110, when the spacing between the air supply component 200 and the heat exchange component 300 changes, the spacing between the second plate 122 and the third plate 123 in the partition 120 along the first direction X can be changed to adapt to the change in the spacing between the air supply component 200 and the heat exchange component 300. For example, when the distance between the air supply assembly 200 and the heat exchange assembly 300 increases, the second plate 122 is positioned further away from the heat exchange assembly 300, and when the distance between the air supply assembly 200 and the heat exchange assembly 300 decreases, the second plate 122 is positioned closer to the heat exchange assembly 300. In this solution, regardless of how the spacing between the air supply assembly 200 and the heat exchange assembly 300 changes, the opening 1222 of the second plate 122 can adapt to the position change of the air supply assembly 200. Therefore, there is no need to change the shape of the air supply assembly 200 or the matching relationship between the partition 120 and other components in the air handling unit 10. For example, while the partition in the original product matches the water receiving tray, the partition 120 in the modified product can still maintain the original matching method with the water receiving tray 400. In other words, when the distance between the air supply assembly 200 and the heat exchange assembly 300 changes, it is only necessary to change the shape of the partition 120 to adapt, and the cost of modifying the internal structure layout of the air handling unit 10 is reduced.

[0098] The specific connection method of the first plate 121, the second plate 122, and the third plate 123 depends on actual needs. In some embodiments, the first plate 121, the second plate 122, and the third plate 123 can be integrally bent from a flat sheet metal, with the first side 1211 and the second side 1212 being the bends of the sheet metal. In some embodiments, the first plate 121, the second plate 122, and the third plate 123 can be integrally injection molded. In some embodiments, the first plate 121 and the second plate 122 can be connected by heat fusion or welding, and the first plate 121 and the third plate 123 can also be connected by heat fusion or welding.

[0099] The junctions between the first plate 121 and the second plate 122 and between the first plate 121 and the third plate 123 can be right-angle transitions or rounded-angle transitions. Figure 7 In this embodiment, there is a rounded transition between the first plate 121 and the second plate 122 , and there is a rounded transition between the first plate 121 and the third plate 123 .

[0100] The first side 1211 and the second side 1212 can be arranged in parallel, or they can be arranged crosswise. In some embodiments, when the air supply assembly 200 only translates along the first direction X during a product modification, the first side 1211 and the second side 1212 can be arranged in parallel. In other embodiments, when the air supply assembly 200 both translates along the first direction X and deflects in a direction perpendicular to the first direction X during a product modification, the first side 1211 and the second side 1212 can be arranged crosswise. This solution can further adapt to changes in the position of the air supply assembly 200, thereby further reducing the modification cost of the air handling unit 10. When the first side 1211 and the second side 1212 are cross-arranged, the second plate 122 and the third plate 123 are relatively deflected. At this time, the axis of the opening 1222 on the second plate 122 is basically parallel to the direction of the airflow derived from the air supply component 200 and crosses the first direction X, and the thickness direction of the third plate 123 crosses the direction of the airflow derived from the air supply component 200 and is basically parallel to the first direction X.

[0101] See also Figure 7-10In some embodiments, the partition 120 further includes a side wing plate 124 adapted to connect to the housing 110. The side wing plate 124 extends along the first direction X and is located on one side of the first plate 121 along the third direction Z. Herein, the direction parallel to the first side edge 1211 is defined as the third direction Z. The side wing plate 124 connects to at least one of the first plate 121, the second plate 122, and the third plate 123 along one side of the first direction X. In this embodiment, the side wing plates 124 are connected to both sides of the second plate 122 and both sides of the third plate 123 along the third direction Z. In other embodiments, the side wing plates 124 may also be provided on both sides of the first plate 121 along the third direction Z. The side wing plates 124 can be integrally formed using a bending process. This can increase the contact area between the side wing plates 124 and the housing 110, thereby enhancing the stability of the connection between the partition 120 and the housing 110. In other embodiments, the side wing plates 124 can also be connected to the third side 1221 of the second plate body 122 and / or the fourth side 1231 of the third plate body 123, that is, the side wing plates 124 are provided at the peripheral position of the partition 120, which can further improve the connection stability of the partition 120.

[0102] The specific connection method between the side wing plate 124 and the housing 110 can be determined according to actual needs. In some embodiments, the side wing plate 124 can be provided with a threaded through hole, through which the side wing plate 124 is threadedly connected to the housing 110. The housing 110 plate body can also be provided with an inwardly tilted buckle 1111, and the side wing plate 124 is sandwiched between the buckle 1111 and the plate body to engage with the housing 110. In other embodiments, the side wing plate 124 can also be glued or welded to the housing 110.

[0104] See also Figure 3-Figure 4 ,as well as Figure 7 The housing 110 includes an upper plate 111, a lower plate 112, a back plate 113, and side plates 114. The back plate 113 and the side plates 114 are located between the upper plate 111 and the lower plate 112. The upper plate 111 is the plate above the housing 110 in the actual working position of the air conditioner. The upper plate 111 can be an independent plate, a collection of multiple plates, or a plate integrally connected to the back plate 113 and / or side plates 114 of the housing 110. Figure 3In this embodiment, the upper plate 111 is integrally connected to the back plate 113. The lower plate 112 is the plate below the shell 110 in the actual working position of the air conditioner. The lower plate 112 can be an independent plate, a collection of multiple plates, or a plate integrally connected to the back plate 113 and / or the side plate 114 of the shell 110. In this embodiment, the lower plate 112 is a plate formed by splicing two plates, and one of the plates of the lower plate 112 is in the shape of a fence and forms an air inlet 118; the other plate of the lower plate 112 is detachably connected to the main body of the air conditioner. When the air conditioner is repaired, it can be disassembled to facilitate observation of the internal structure of the air conditioner. In particular, the lower end of the partition 120 is connected to the intersection of the two sub-plates of the lower plate 112. In this embodiment, the air inlet 118 is provided on the lower plate 112 . In other embodiments, the air inlet 118 may also be provided on the upper plate 111 , the back plate 113 or the side plate 114 of the housing 110 .

[0105] See also Figure 3-Figure 4 ,as well as Figure 7 In this embodiment, the second plate 122 is located above the third plate 123, and the third side 1221 of the second plate 122 is connected to the upper plate 111, and the fourth side 1231 of the third plate 123 is connected to the lower plate 112. At this time, airflow outside the housing 110 enters the first chamber 115 through the air inlet 118 on the lower plate 112, and flows upward through the opening 1222 of the second plate 122 to the second chamber 116. In other embodiments, the air inlet 118 can be set on the upper plate 111 or the back plate 113, with the third side 1221 of the second plate 122 connected to the lower plate 112, and the fourth side 1231 of the third plate 123 connected to the upper plate 111.

[0106] In some embodiments, the upper plate body 111 can also be formed by splicing together a first sub-plate body and a second sub-plate body. The first sub-plate body is independently provided or integrally connected to the back plate 113, and the second sub-plate body is integrally formed with the partition 120 (specifically, it can be bent into shape). Specifically, the side of the second sub-plate body that abuts the first sub-plate body is connected to the upper side of the partition 120. At this time, the second sub-plate body and the partition 120 form an L-shape. This solution can reduce the number of parts of the shell assembly 100 and facilitate the assembly and positioning of the partition 120. In other embodiments, the first sub-plate body and the partition 120 can be integrally formed (specifically, they can be bent into shape). Specifically, the side of the first sub-plate body that abuts the second sub-plate body is integrally connected to the partition 120, and the other opposite side can be integrally connected to the back plate 113. At this time, the first sub-plate body, the partition 120 and the back plate 113 form a U-shape.

[0107] The relative position of the second plate 122 and the third plate 123 depends on the relative position of the air supply assembly 200 and the heat exchange assembly 300. The air supply assembly 200 in the modified product can be translated compared to the original product, or it can be deflected compared to the original product. In the case where the air supply assembly 200 in the modified product is translated compared to the original product, when the air supply assembly 200 in the modified product is translated away from the heat exchange assembly 300, see Figure 4-Figure 5 as well as Figure 14 In some embodiments, along the first direction X, the second plate 122 can be located on the side of the third plate 123 facing the first chamber 115. That is, compared to the straight plate-shaped partition before the modification, the side of the modified partition 120 close to the air supply assembly 200 (i.e., the second plate 122) is offset in the direction away from the heat exchange assembly 300, thereby adapting to the position change of the air supply assembly 200. When the air supply assembly 200 in the modified product moves toward the heat exchange assembly 300, see Figure 13 In some embodiments, along the first direction X, the second plate 122 is located on the side of the third plate 123 facing the second chamber 116. This means that, compared to the pre-modified straight partition, the side of the modified partition 120 proximal to the air supply assembly 200 (i.e., the second plate 122) is offset toward the heat exchange assembly 300, thereby adapting to the positional changes of the air supply assembly 200. If the air supply assembly 200 in the modified product is deflected compared to the original product, the second plate 122 can also be deflected relative to the third plate 123.

[0108] The first plate 121 can be arranged horizontally or tilted. Figure 4-Figure 5 , and see Figure 13-14 In some embodiments, the direction from the first side 1211 to the second side 1212 is parallel to the first direction X. When the first direction X is parallel to the horizontal direction, the thickness direction of the first plate 121 is parallel to the vertical direction. In this solution, when the second plate 122 and the third plate 123 are spaced the same distance apart along the first direction X, the size of the first plate 121 along the first direction X can be minimized, thereby reducing the overall material consumption of the partition 120. Figure 15In some embodiments, the direction from the first side 1211 to the second side 1212 intersects the first direction X, and along the second direction Y, the first side 1211 is located on the side of the second side 1212 facing away from the third plate 123. In this solution, the bending angles between the first plate 121 and the second plate 122, and between the first plate 121 and the third plate 123, are smaller. When the partition 120 is formed by bending a sheet metal part, the small bending angle can reduce the bending performance requirements of the partition 120. When the partition 120 is integrally injection molded, the small bending angle facilitates demolding, reducing the difficulty of manufacturing the partition 120. Specifically, in this embodiment, the angle between the direction from the first side 1211 to the second side 1212 and the first direction X can be between 45° and 89°. For example, the angle between the direction from the first side 1211 to the second side 1212 and the first direction X can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85° or 89°, etc. Figure 16 In some embodiments, the direction from the first side 1211 to the second side 1212 intersects the first direction X, and along the second direction Y, the first side 1211 is located on the side of the second side 1212 that faces the third plate 123. In this solution, the bending angle between the first plate 121 and the second plate 122 is larger, and the bending angle between the first plate 121 and the third plate 123 is also larger. When viewed along the first direction X, the first plate 121 is located within the overlapping region of the second plate 122 and the third plate 123. In this solution, the partition 120 is elastic as a whole, allowing the second plate 122 and the third plate 123 to move closer or further away within a small range, thereby compensating for processing or assembly errors. When the distance between the second plate 122 and the third plate 123 is too small or too large, the distance between the second plate 122 and the third plate 123 can be stretched or compressed to compensate for processing or assembly errors. Specifically, in this embodiment, the angle between the direction from the first side 1211 to the second side 1212 and the first direction X can be between 91° and 135°. For example, the angle between the direction from the first side 1211 to the second side 1212 and the first direction X can be 91°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, or 135°. Figure 17 The thickness directions of the second plate body 122 and the fourth plate body can also be arranged to intersect with the first direction X.

[0109] The placement of the partition 120 in the housing 110 depends on actual needs, see Figure 4-Figure 5 , and see Figure 13-14In some embodiments, the direction from the first side 1211 to the third side 1221 is approximately perpendicular to the first direction X. In this embodiment, when the first direction X is parallel to the horizontal direction, the thickness direction of the second plate 122 is parallel to the horizontal direction, that is, the second plate 122 is arranged vertically. This embodiment further facilitates the connection between the second plate 122 and the housing 110. It should be noted that the terms "approximately" and "substantially" used herein to define data or orientations indicate an error range of less than 10%. For example, "the direction from the first side 1211 to the third side 1221 is approximately perpendicular to the first direction X" means that the angle between the direction from the first side 1211 to the third side 1221 and the first direction X can be between 81° and 99°. For example, the angle between the direction from the first side 1211 to the third side 1221 and the first direction X can be 81°, 85°, 90°, 95°, or 99°, etc. In other embodiments, the second plate 122 may also be arranged obliquely, that is, the direction from the first side 1211 to the third side 1221 is not substantially perpendicular to the first direction X. Figure 4-Figure 5 , and see Figure 13-14 In some embodiments, the direction from the second side 1212 to the fourth side 1231 is substantially perpendicular to the first direction X. In this solution, when the first direction X is parallel to the horizontal direction, the thickness direction of the third plate 123 is parallel to the horizontal direction, that is, the third plate 123 is arranged vertically. This solution makes it easier to connect the third plate 123 to the housing 110. Figure 4-Figure 5 , and see Figure 13-14 In some embodiments, the direction from the first side 1211 to the third side 1221 is substantially perpendicular to the direction from the first side 1211 to the second side 1212. In this solution, the thickness direction of the first plate 121 is substantially perpendicular to the thickness direction of the second plate 122. Figure 4-Figure 5 , and see Figure 13-14 In some embodiments, the direction from the second side 1212 to the fourth side 1231 is substantially perpendicular to the direction from the second side 1212 to the first side 1211. In this solution, the thickness direction of the first plate 121 is substantially perpendicular to the thickness direction of the third plate 123. In other embodiments,

[0110] See also Figures 1-17 The third aspect of the present invention further provides an air handling unit 10, which can be an indoor unit of an air conditioner. The air handling unit 10 includes any of the above-mentioned shell components 100, air supply components 200, and heat exchange components 300.

[0111] The air supply assembly 200 is disposed in the first chamber 115 of the housing 110 and is used to guide the air in the first chamber 115 to the second chamber 116 through the opening 1222. Figure 1-Figure 4 as well as Figure 10 The air supply assembly 200 is a turbofan assembly. The air supply assembly 200 includes one or more drive motors 210, one or more volutes 220, and a number of impellers 230 that matches the number of volutes 220. Each impeller 230 is disposed in a one-to-one correspondence within each volute 220. Specifically, in this embodiment, the air supply assembly 200 includes two drive motors 210, four volutes 220, and four impellers 230. Each drive motor 210 drives a corresponding impeller 230 located on both sides thereof along the third direction Z. The air supply assembly 200 also includes a drive shaft connected to each impeller 230. The drive shaft passes through each volute 220 and connects to each impeller 230. The two drive motors 210 drive the drive shafts to rotate, thereby driving each impeller 230 to rotate within the corresponding volute 220. This in turn draws air from outside the volute 220 in the first chamber 115 into the volute 220 and transmits the air to the second chamber 116 through the opening 1222 on the partition 120. The arrangement of the volutes 220 of the air supply assembly 200 depends on specific needs. In this embodiment, the volutes 220 are spaced apart along the third direction Z. The partition 120 has the same number of openings 1222 as the volutes 220. The openings 1222 are spaced apart along the third direction Z, and each volute 220 delivers air to a corresponding opening 1222. The heat exchange assembly 300 is disposed within the second chamber 116 and is used to exchange heat with the airflow transmitted by the heat exchange airflow. The heated or cooled air is then delivered to the exterior of the housing 110.

[0112] When the heat exchange assembly 300 cools the air, the temperature of the heat exchange assembly 300 is lower than the ambient temperature, and condensed water is easily condensed on the heat exchange assembly 300. In order to prevent the condensed water from dripping and affecting the internal components of the air handling unit 10, see Figure 4-Figure 6 In some embodiments, the air handling unit 10 further includes a water tray 400 disposed within the second chamber 116. The water tray 400 is disposed below the heat exchange assembly 300 and is used to receive condensed water dripping from the heat exchange assembly 300. The water tray 400 may only store condensed water and remove the received condensed water through evaporation. The water tray 400 may also be provided with a water outlet, through which the condensed water is discharged after being received by the water tray 400. In this embodiment, the wall surface of the third plate 123 facing away from the first chamber 115 abuts the water tray 400. In this solution, the water tray 400 is used to position the partition 120 relative to the housing 110. This not only improves the stability of the partition 120 but also pre-positions the partition 120, reducing the difficulty of assembling the partition 120.

[0113] See also Figure 4-Figure 7In some embodiments, the lower end of the third plate 123 is bent in a direction away from the water receiving tray 400 to form a step portion 1232 (it should be noted that the "bending" in the above text is only used to express the shape of the step portion 1232, and does not limit the molding process of the step portion 1232. The step portion 1232 can be formed by a bending process or can be integrally injection molded by an injection molding process). The wall surface of the step portion 1232 away from the first chamber 115 includes a first step wall 12321 extending laterally and a second step wall 12322 extending vertically. The upper end of the second step wall 12322 is connected to the end of the first step wall 12321 close to the first chamber 115. The water receiving tray 400 includes an abutting end 410 that abuts the partition 120. A first stepped wall 12321 abuts the upper wall surface of the abutting end 410, thereby defining the height position of the partition 120. A second stepped wall 12322 abuts the side wall surface of the abutting end 410 facing the first chamber 115, thereby defining the relative position of the partition 120 and the air supply assembly 200 along the first direction X. In this solution, by having the two walls of the stepped portion 1232 abut the two walls of the abutting end 410, the water receiving tray 400 can simultaneously determine the vertical and horizontal orientation of the partition 120, thereby achieving better positioning. In other embodiments, in order to achieve the positioning of the partition 120, the end of the water receiving tray 400 near the air supply assembly 200 can be provided with a vertically arranged through hole, and the fourth side 1231 of the third plate body 123 is passed through the through hole of the water receiving tray 400 and is thereby connected to the lower plate body 112 of the shell 110. In this solution, the outer periphery of the fourth side 1231 around the vertical axis is in contact with the inner wall of the through hole, which has a better positioning effect. In addition to the fourth side 1231 being passed through the through hole as a whole, in another embodiment, the fourth side 1231 can also be partially passed through the through hole. Specifically, the fourth side 1231 of the third plate body 123 is provided with a protruding structure, which is passed through the through hole of the water receiving tray 400, and the other structures of the third plate body 123 except the protruding structure are connected to the lower plate body 112. In addition to the water receiving tray 400 positioning the partition 120, in some embodiments, the partition 120 can also be used to position the water receiving tray 400. Specifically, when the partition 120 is integrally formed with the first sub-plate body or the second sub-plate body in the upper plate body 111, the upper end of the water receiving tray 400 facing the heat exchange component 300 can be provided with a groove, and the fourth side 1231 of the third plate body 123 is embedded in the groove, and the fourth side 1231 of the third plate body 123 can slide into or out of the groove of the water receiving tray 400 along the third direction Z. In this solution, when the water receiving tray 400 is assembled, the port of the groove along the third direction Z can be aligned with the fourth side 1231 of the partition 120, and the water receiving tray 400 can be driven to slide along the third direction Z to achieve the installation of the water receiving tray 400. After the water receiving tray 400 is installed, the third plate body 123 of the partition 120 can achieve the positioning of the water receiving tray 400, so that the assembly and positioning of the water receiving tray 400 can be completed in one action, and the operation is simpler.

[0114] Moreover, since the second plate body 122 and the third plate body 123 of the partition 120 in this embodiment are staggered along the first direction X, when the air supply assembly 200 in the modified product is translated along the first direction X, the partition 120 can still be positioned by the water receiving tray 400, so that the matching structure between the water receiving tray 400 and the partition 120 does not need to be adjusted in the modified product, and the original mold of the water receiving tray 400 can continue to be used in the modified product, thereby reducing the modification cost.

[0115] During a product modification, if the relative distance between the air supply assembly 200 and the heat exchange assembly 300 changes, the airflow generated by the air supply assembly 200 will theoretically change its relative coverage area of ​​the heat exchange assembly 300. For example, when the relative position between the air supply assembly 200 and the heat exchange assembly 300 becomes farther, the airflow exiting the air supply assembly 200 diverges, reducing the flow rate received by the heat exchange assembly 300. When the relative position between the air supply assembly 200 and the heat exchange assembly 300 becomes closer, the flow rate received by the heat exchange assembly 300 remains unchanged, but the flow density of the airflow received by one part of the heat exchange assembly 300 increases, while the flow density of the airflow received by another part decreases. In either case, the heat exchange efficiency of the heat exchange assembly 300 decreases. Therefore, in order to ensure that the airflow generated by the air supply assembly 200 in the modified product can efficiently exchange heat with the heat exchange assembly 300, it is necessary to adjust the shape of the heat exchange assembly 300, or adjust the outlet angle of the air outlet 119 of the air supply assembly 200, so that the airflow sent by the air supply assembly 200 can basically cover the heat exchange assembly 300, so as to avoid the airflow directed from the air supply assembly 200 to the heat exchange assembly 300 not being able to cover the heat exchange assembly 300, thereby reducing the heat exchange efficiency of the heat exchange assembly 300, or the airflow coverage area directed from the air supply assembly 200 to the heat exchange assembly 300 being much larger than the windward area of ​​the heat exchange assembly 300, thereby reducing the heat exchange efficiency of the heat exchange assembly 300. However, adjusting the shape of the air supply assembly 200 will increase the modification cost.

[0116] In view of this, in order to further reduce the cost of modification, see Figure 7-12In some embodiments, the air supply assembly 200 includes a volute 220 and a wind wheel 230 disposed within the volute 220. The volute 220 includes an air outlet 221 (the air outlet 221 is specifically a portion of the volute 220 such as a volute tongue 222 for discharging air). The air handling unit 10 also includes a first guide plate 130a for guiding the airflow discharged from the air outlet 221. The first guide plate 130a is used to guide the airflow discharged from the air outlet 221. The first guide plate 130a can be fixed in various ways. In some embodiments, the air outlet 221 is provided through the opening 1222, and the first guide plate 130a is connected to the edge of the port of the air outlet 221. The first guide plate 130a can adjust the air outlet direction or angle of the air supply assembly 200. In this solution, when the distance between the air supply component 200 and the heat exchange component 300 changes, there is no need to modify the structure of the original heat exchange component 300. Only a new guide plate is needed to solve the problem of reduced heat exchange efficiency of the heat exchange component 300 due to the change in the position of the air supply component 200 and the heat exchange component 300.

[0117] In the aforementioned scheme, the air outlet 221 is passed through the opening 1222 of the partition 120, and the first guide plate 130a is connected to the air outlet 221. In other embodiments, the air outlet 221 may also be located in the first chamber 115, and the first guide plate 130a is connected to the port edge of the air outlet 221, and the first guide plate 130a is passed through the opening 1222. In this embodiment, the first guide plate 130a passes through the opening 1222 of the partition 120, which eliminates the positioning of the partition 120 and the air supply assembly 200. The structural design of the partition 120 does not need to be constrained by the structure and position of the air supply assembly 200, making the structural design of the partition 120 more flexible. In the aforementioned two embodiments, the first guide plate 130a is connected to the air outlet 221, so that the first guide plate 130a can guide the airflow leading out of the air outlet 221,

[0118] In other embodiments, the first guide plate 130a may not be connected to the air outlet portion 221. Specifically, the first guide plate 130a may be disposed within the second chamber 116 and connected to the outer edge of the opening 1222 of the partition 120, so that the airflow directed from the first chamber 115 to the second chamber 116 through the opening 1222 of the partition 120 can be guided by the first guide plate 130a. Furthermore, in this embodiment, the air outlet portion 221 may or may not be disposed through the opening 1222 of the partition 120. Since the first guide plate 130a is not connected to the air outlet portion 221, there is no need to provide a connection structure between the air outlet portion 221 and the first guide plate 130a. This allows the appearance of the air supply assembly 200 in the modified product to essentially retain the same appearance as before the modification, further reducing modification costs.

[0119] To enhance the airflow diversion effect, in some embodiments, the air handling unit 10 may include multiple first airflow guides 130a. To facilitate distinguishing between the airflow guides, the following description uses two of the airflow guides as an example, and the two airflow guides are named first airflow guide 130a and second airflow guide 130b, respectively. The first airflow guide 130a may be located below the axis of the opening 1222, and the second airflow guide 130b may be located above the axis of the opening 1222. Along the first direction X, the first airflow guide 130a is arranged downwardly and tilted. Under the guidance of the first airflow guide 130a, a portion of the airflow exiting the opening 1222 of the partition 120 is directed downwardly. Along the first direction X, the second airflow guide 130b is arranged horizontally. Under the guidance of the second airflow guide 130b, a portion of the airflow exiting the opening 1222 of the partition 120 is directed horizontally. In this solution, the inclination angle of the first guide plate 130a can be adjusted to adjust the distance between the opening 1222 and the heat exchange assembly 300, so that the airflow is directed as completely as possible to all parts of the heat exchange assembly 300, thereby improving the heat exchange efficiency of the heat exchange assembly 300. In other embodiments, additional guide plates can be provided on both sides of the opening 1222 of the partition plate 120 along the third direction Z, which will not be described in detail here.

[0120] When the first guide plate 130a is connected to the partition 120, since there is an angle between the first guide plate 130a and the partition 120, it is difficult for the first guide plate 130a and the partition 120 to be relatively fixed. In order to solve the above problem, see Figure 12 In some embodiments, the first deflector 130a has an upwardly turned flange on a side adjacent to the partition 120. The flange fits against the sidewall of the partition 120 facing away from the air supply assembly 200. The flange can be welded, glued, screwed, or riveted to the partition 120. The flange's structural design increases the contact area with the partition 120, thereby enhancing the connection strength between the first deflector 130a and the partition 120. Furthermore, the flange design allows the deflector wall surface of the first deflector 130a to be flush with the outer perimeter of the opening 1222 of the partition 120, thereby enhancing the deflection effect of the first deflector 130a.

[0121] See also Figure 10-12 In some embodiments, the air supply assembly 200 includes a volute 220 and a wind wheel 230 disposed in the volute 220, the housing 110 includes a back plate 113 located on a side of the air supply assembly 200 facing away from the partition 120, and the air handling unit 10 satisfies at least one of the following conditions a)-c):

[0122] a) See Figure 11Along the first direction X, the minimum distance L1 between the volute 220 and the backplate 113 satisfies: L1 ≥ 10 mm. For example, the minimum distance L1 between the volute 220 and the backplate 113 can be 10 mm, 11 mm, 12 mm, or 13 mm, etc. It should be noted that in this embodiment, L1 is defined as the minimum distance between the backplate 113 and the volute 220 when viewed along the third direction Z. That is, when the outer periphery of the backplate 113 is provided with a flange facing the air supply assembly 200, the minimum distance between the volute 220 and the backplate 113 is the minimum distance between the volute 220 and the flange along the first direction X. When the minimum distance between the volute 220 and the backplate 113 meets the above requirements, assembly of the volute 220 can be facilitated.

[0123] b) See Figure 11-12 The minimum distance L2 between the impeller 230 and the inner wall of the volute 220 satisfies the following requirement: L2 ≥ 4.5 mm. For example, the minimum distance L2 between the impeller 230 and the inner wall of the volute 220 can be 4.5 mm, 5 mm, 5.5 mm, or 6 mm. The minimum distance L2 between the impeller 230 and the inner wall of the volute 220 has a significant impact on the noise in the air duct. Testing of noise and air volume has shown that when L2 ≥ 4.5 mm, the noise of the air supply assembly 200 can be further reduced and the air volume of the air supply assembly 200 can be increased.

[0124] c) See Figure 11-12 The volute 220 includes a volute tongue 222. The radius r1 of the volute tongue 222 and the radius r2 of the impeller 230 satisfy the following relationship: 0.1r2≤r1≤0.2r2. For example, the radius r1 of the volute tongue 222 can be 0.1r2, 0.12r2, 0.14r2, 0.16r2, 0.18r2, or 0.2r2. This solution can further reduce the noise of the air supply assembly 200 and increase the air output of the air supply assembly 200.

[0125] In the related art, the electric control box is arranged in the shell and on the side of the air supply component away from the heat exchange component. This layout has the following defects: ① When the motor rotates at a high speed, the vibration of the volute may hit the electric control box, generating a lot of noise; generally, pearl cotton is placed between the electric control box and the volute to isolate the two and reduce the vibration of the volute. This solution increases the cost and reduces the production efficiency; ② The volute is set forward, closer to the evaporator, and the wind pressure is greater, which is not good for noise and air volume.

[0126] In view of this, in some embodiments, the air handling unit 10 further includes an electric control box 500, which is disposed on one side of the air supply assembly 200 along the third direction Z. In some embodiments, the housing 110 includes a side panel 114 located on one side of the air supply assembly 200 along the third direction Z. The electric control box 500 is disposed inside the housing 110 and between the side panel 114 and the air supply assembly 200.
