[0061] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] 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.

[0064] 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.

[0065] In view of this, referring to Figures 1-17, this embodiment provides a partition 120, which is used in 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.

[0066] Referring to Figures 1-4, as well as Figures 7 and 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 within 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 defines an opening 1222 connecting the first chamber 115 and the second chamber 116. For ease of description, referring to Figure 4, the direction from the first chamber 115 to the second chamber 116 is defined as the first direction X.

[0067] Referring to Figures 1-4, the 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 configured 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 drawn 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 directed out of the housing 110 through the air outlet 119. Before being directed out of the housing 110, the airflow driven into the second chamber 116 by the air supply assembly 200 exchanges heat with the heat exchange assembly 300 located within the second chamber 116, thereby regulating the temperature of the air exiting the housing 110.

[0068] 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.

[0069] Referring to Figures 4 and 7-9, 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, width, or length 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 used as the height of the air conditioner as an example.

[0070] 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 facing 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. Referring to Figures 4, 10 and 11, in some embodiments, the air supply assembly 200 is fixed to the partition 120, and the air outlet portion 221 of the air supply assembly 200 is provided with the opening 1222 of the second plate 122. On the one hand, it is convenient for the air supply assembly 200 to guide the air in the first chamber 115 to the second chamber 116, and on the other hand, it can also improve 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 is located in the first chamber 115, and the air outlet 221 of the air supply assembly 200 is opposite to the opening 1222 of the partition 120, so as to facilitate guiding the airflow in the first chamber 115 to the second chamber 116.

[0071] 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 facing away from the second side 1212 is a 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. Referring to Figure 7, along the first direction X, the third plate 123 is spaced apart from the second plate 122. Along the second direction Y, the third plate 123 is at least partially located on a side of the second plate 122 proximal 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 to the overall straight plate-shaped structure of the partition 120, in this embodiment, because the second plate 122 and the third plate 123 can be located at different positions within the housing 110 along the first direction X, when the spacing between the air supply assembly 200 and the heat exchange assembly 300 changes, the spacing between the air supply assembly 200 and the heat exchange assembly 300 can be adapted by changing the spacing between the second plate 122 and the third plate 123 in the partition 120 along the first direction X. 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; 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 change the matching relationship between the partition 120 and other components within the air handling unit 10. For example, while the partition in the original product matches the water tray, the partition 120 in the modified product can still maintain the original matching method with the water tray 400. In other words, when the spacing between the air supply assembly 200 and the heat exchange assembly 300 changes, only the shape of the partition 120 needs to be changed to adapt, which reduces the cost of modifying the internal structural layout of the air handling unit 10.

[0072] 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.

[0073] The intersection between the first plate 121 and the second plate 122 and between the first plate 121 and the third plate 123 can be a right-angle transition or a rounded transition. Referring to Figure 7, in this embodiment, the first plate 121 and the second plate 122 have a rounded transition, and the first plate 121 and the third plate 123 have a rounded transition.

[0074] 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.

[0075] Referring to Figures 7-10 , in 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 a first direction X and is located on one side of the first plate 121 along a 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 may be integrally formed using a bending process. This increases the contact area between the side wing plates 124 and the housing 110, thereby enhancing the secure 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.

[0076] 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.

[0077] Referring to Figures 1-4, 7, and 13-17, an embodiment of the second aspect of the present application further provides a housing assembly 100. The housing assembly 110 is used in an air handling unit 10, which may specifically be an indoor unit of an air conditioner. The housing assembly 100 includes the housing 110 of any of the aforementioned embodiments and the partition 120 of any of the aforementioned embodiments.

[0078] Referring to Figures 3-4 and 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 side plates 114 are located between the upper plate 111 and the lower plate 112. The upper plate 111 is the upper portion of the housing 110 when the air conditioner is in the actual operating position. The upper plate 111 can be a single plate, a combination of multiple plates, or a plate integrally connected to the back plate 113 and / or side plates 114 of the housing 110. Referring to Figure 3, in this embodiment, the upper plate 111 is integrally connected to the back plate 113. The lower plate 112 is the lower portion of the housing 110 when the air conditioner is in the actual operating position. The lower plate 112 can be a single plate, a combination of multiple plates, or a plate integrally connected to the back plate 113 and / or side plates 114 of the housing 110. In this embodiment, the lower plate 112 is composed of two panels, one of which is fence-shaped and forms an air inlet 118. The other panel of the lower plate 112 is detachably connected to the main body of the air conditioner, allowing for easy access to the internal structure of the air conditioner during maintenance. Specifically, the lower end of the partition 120 is connected to the junction of the two panels of the lower plate 112. In this embodiment, the air inlet 118 is located on the lower plate 112. In other embodiments, the air inlet 118 can also be located on the upper plate 111, back plate 113, or side plate 114 of the housing 110.

[0079] Referring to Figures 3-4 and 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, while 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 provided 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.

[0080] 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.

[0081] 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, refer to Figures 4-5 and 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, relative to the straight plate-shaped partition before the modification, the side of the modified partition 120 close to the air supply assembly 200 (that is, 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 translates toward the heat exchange assembly 300, as shown in FIG13 , 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. That is, compared to the pre-modified straight-plate 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 change of the air supply assembly 200. If the air supply assembly 200 in the modified product is deflected relative to the original product, the second plate 122 can also be deflected relative to the third plate 123.

[0082] The first plate 121 can be arranged horizontally or at an angle. (See Figures 4-5 and 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 of the first plate 121 is parallel to the vertical direction. In this embodiment, when the second plate 122 and the third plate 123 are spaced the same distance apart along the first direction X, the dimension of the first plate 121 along the first direction X can be minimized, thereby reducing the overall material consumption of the partition 120. (See Figure 15.) 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 facing away from the third plate 123. In this embodiment, 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 can facilitate 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. Referring to FIG. 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 embodiment, 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. Furthermore, 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 embodiment, 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 spacing between the second plate 122 and the third plate 123 is too small or too large, the spacing 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°. Exemplarily, 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°, etc.17 , the thickness directions of the second plate 122 and the fourth plate may also be arranged to intersect with the first direction X.

[0083] The placement of the partition 120 within the housing 110 depends on actual needs. See Figures 4-5 and 13-14. In some embodiments, the direction from the first side 1211 to the third side 1221 is substantially 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 arrangement facilitates 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 percent. 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 can be arranged at an angle, that is, the direction from the first side 1211 to the third side 1221 is not approximately perpendicular to the first direction X. Referring to Figures 4-5 and 13-14, in some embodiments, the direction from the second side 1212 to the fourth side 1231 is approximately 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 shell 110. Referring to Figures 4-5, and Figures 13-14, in some embodiments, the direction from the first side 1211 to the third side 1221 is roughly 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 roughly perpendicular to the thickness direction of the second plate 122. Referring to Figures 4-5, and Figures 13-14, in some embodiments, the direction from the second side 1212 to the fourth side 1231 is roughly 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 roughly perpendicular to the thickness direction of the third plate 123. In other embodiments,

[0084] 1 to 17 , a third aspect of the present application further provides an air handling unit 10 , which may 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 .

[0085] The air supply assembly 200 is disposed in the first chamber 115 within the housing 110 and is used to direct the air within the first chamber 115 to the second chamber 116 through the opening 1222. Referring to Figures 1-4 and 10, the air supply assembly 200 is a turbofan assembly, comprising 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 corresponding manner 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 either side of the drive motor 210 along the third direction Z. The air supply assembly 200 also includes a drive shaft connected to each wind wheel 230. The drive shaft passes through each volute 220 and is connected to each wind wheel 230. The two drive motors 210 drive the drive shaft to rotate, thereby driving each wind wheel 230 to rotate within the corresponding volute 220, thereby sucking air outside the volute 220 in the first chamber 115 into the volute 220 and transmitting it to the second chamber 116 through the opening 1222 on the partition 120. The arrangement orientation of each volute 220 of the air supply assembly 200 depends on specific needs. In this embodiment, the volutes 220 are arranged at intervals along the third direction Z. The partition 120 has the same number of openings 1222 as the number of volutes 220. The openings 1222 are arranged at intervals along the third direction Z, and each volute 220 transmits airflow to one opening 1222. The heat exchange assembly 300 is disposed in the second chamber 116 . The heat exchange assembly 300 is used to perform heat exchange with the air flow transmitted by the heat exchange air flow, and the heated or cooled air is transmitted to the outside of the housing 110 .

[0086] When the heat exchange component 300 cools the air, the temperature of the heat exchange component 300 is lower than the ambient temperature, and condensed water is easily condensed on the heat exchange component 300. In order to prevent the condensed water from dripping and affecting the internal components of the air handling unit 10, referring to Figures 4 to 6, in some embodiments, the air handling unit 10 also includes a water receiving tray 400 provided in the second chamber 116. The water receiving tray 400 is provided below the heat exchange component 300 and is used to receive the condensed water dripping from the heat exchange component 300. The water receiving tray 400 can only store the condensed water and remove the received condensed water by evaporation; the water receiving tray 400 can also be provided with a water outlet. After the water receiving tray 400 receives the condensed water, the condensed water is discharged through the water outlet. In this embodiment, the third plate 123 is away from the wall of the first chamber 115 and abuts against the water receiving tray 400. In this solution, the water receiving tray 400 is used to position the relative position of the partition 120 and the shell 110. On the one hand, it can improve the positioning stability of the partition 120, and on the other hand, it can also form a pre-positioning for the partition 120, thereby reducing the difficulty of assembling the partition 120.

[0087] 4-7 , in 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” mentioned above 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 one 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.

[0088] 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.

[0089] 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.

[0090] In view of this, in order to further reduce the cost of modification, referring to Figures 7 to 12, in some embodiments, the air supply assembly 200 includes a volute 220 and a wind wheel 230 disposed in 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 guiding the airflow). The air handling unit 10 also includes a first guide plate 130a for guiding the airflow guided out of the air outlet 221. The first guide plate 130a is used to guide the airflow guided out of the air outlet 221. The first guide plate 130a has multiple fixing methods. In some embodiments, the air outlet 221 is provided through the opening 1222. 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.

[0091] 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,

[0092] 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.

[0093] 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.

[0094] When the first deflector 130a is connected to the partition 120, the angle between the first deflector 130a and the partition 120 makes it difficult to fix the first deflector 130a and the partition 120 relative to each other. To address this issue, referring to FIG12 , in some embodiments, the first deflector 130a is provided with an upwardly turned flange on the side of the first deflector 130a adjacent to the partition 120. The flange fits against the side wall 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 can increase the contact area with the partition 120, thereby improving 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 periphery of the opening 1222 of the partition 120, thereby improving the deflection effect of the first deflector 130a.

[0095] 10-12 , in some embodiments, the air supply assembly 200 includes a volute 220 and a wind wheel 230 disposed within 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):

[0096] a) Referring to Figure 11 , along the first direction X, the minimum distance L1 between the volute 220 and the backplate 113 satisfies the following requirement: 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 as 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.

[0097] b) Referring to Figures 11-12 , the minimum distance L2 between the impeller 230 and the inner wall of the volute 220 satisfies the 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 significantly impacts the noise in the air duct. Testing of noise and air volume revealed 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.

[0098] c) Referring to Figures 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.

[0099] 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.

[0100] In view of this, in some embodiments, the air handling unit 10 further includes an electrical 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 electrical control box 500 is disposed within the housing 110 and between the side panel 114 and the air supply assembly 200. In other embodiments, the electrical control box 500 is disposed outside the housing 110 and on the side of the side panel 114 facing away from the air supply assembly 200. In yet other embodiments, referring to Figures 1-4, a mezzanine space 117 is disposed on the side of the housing 110. The mezzanine space 117 is located on one side of the first chamber 115 along the third direction Z. The mezzanine space 117 is enclosed by a plurality of side panels 114 of the housing 110, and the electrical control box 500 is disposed within the mezzanine space 117. In the above embodiments, the electrical control box 500 is arranged on the left or right side (i.e., on the side of the air supply component 200 along the third direction Z), which can release the rear space of the first chamber 115 (i.e., the space on the side of the air supply component 200 away from the heat exchange component 300); so that the position of the volute 220 can be moved backward, thereby increasing the distance between the volute 220 and the evaporator, increasing the air output of the air supply component 200, and avoiding the vibration of the volute 220 and hitting the electrical control box 500 to generate noise.
