[0047] Compared with the prior art, the beneficial effects of the utility model are:

[0048] In the technical solution of the utility model, the partition includes a first plate body, a second plate body and a third plate body, and the two sides of the first plate body are connected to the second plate body and the third plate body respectively. Since the second plate body and the third plate body can be located at different positions along the first direction in the shell, when the spacing between the air supply component and the heat exchange component changes, the spacing change between the air supply component and the heat exchange component can be adapted by changing the spacing distance between the second plate body and the third plate body in the partition body along the first direction. Exemplarily, when the distance between the air supply component and the heat exchange component increases, the second plate body is set to be farther away from the heat exchange component, and when the distance between the air supply component and the heat exchange component decreases, the second plate body is set to be closer to the heat exchange component. In this solution, no matter how the spacing between the air supply component and the heat exchange component changes, the opening of the second plate body can match the position change of the air supply component, so there is no need to change the shape of the air supply component, or change the matching relationship between the partition and other components in the air handling unit. For example, when the partition and the water receiving tray are matched in the initial product, the partition in the modified product can still maintain the original matching method with the water receiving 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 modification cost when adjusting the internal structure layout of the air handling unit is reduced.

[0088] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0089] The air conditioner includes a housing, a partition, an air supply assembly and a heat exchange assembly arranged in the housing. The partition divides the internal space of the housing into two chambers, and the air supply assembly and the heat exchange assembly are arranged in the two chambers respectively. An opening is arranged on the partition, and the air supply assembly is positioned on the partition, and the air supply assembly guides the airflow to the heat exchange assembly through the opening of the partition.

[0090] In the process of product upgrading, for example, in an actual scenario, the electric 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 electric control box, or to reduce the impact of the vibration of the air supply assembly on the electric control box, it is necessary to move the electric 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 electric control box) is relatively large, 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 outer dimensions of the air supply assembly so that the air supply assembly can cooperate well with the partition, and the cost of 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 outer structure of the water tray needs to be adjusted, and the cost of modification is also high.

[0091] In view of this, see Figure 1-Figure 17 The present embodiment provides a partition plate 120, which is used for an air handling unit 10. By way of example, the present embodiment takes the air handling unit 10 as an air conditioner as an example for explanation. 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 Fig. 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 connected to the first chamber 115 and an air outlet 119 connected to the second chamber 116. The air supply assembly 200 is used to guide the airflow in the first chamber 115 to the second chamber 116 through the opening 1222 of the partition 120. When the airflow in the first chamber 115 is guided to the second chamber 116, a negative pressure is generated in the first chamber 115, so that the air outside the housing 110 is introduced into the first chamber 115 through the air inlet 118 connected to the first chamber 115; at the same time, a positive pressure is generated in the second chamber 116, and the airflow in the second chamber 116 is guided 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 guided out of the housing 110, the airflow exchanges heat with the heat exchange assembly 300 located in the second chamber 116, so that the temperature of the air guided out of the housing 110 can be adjusted.

[0094] The heat exchange assembly 300 is used to exchange heat with the air flowing through it. Specifically, the heat exchange assembly 300 can be used to absorb the heat in the air flowing through it (i.e., the heat exchange assembly 300 is used for cooling), or can be used to direct the heat to the air flowing through it (i.e., the heat exchange assembly 300 is used for heating). The partition 120 can support the air supply assembly 200 on the one hand, and on the other hand, it can prevent the energy of the heat exchange assembly 300 from escaping by dividing 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 body 121, a second plate body 122 and a third plate body 123. The first plate body 121 has a first side 1211 and a second side 1212 arranged opposite to each other. For the convenience 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 orientation 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 , Fig.10 as well as Fig.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 passes through the opening 1222 of the second plate 122, which is convenient for the air supply assembly 200 to guide the air in the first chamber 115 to the second chamber 116, and 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 directly opposite to the opening 1222 of the partition 120, so as to facilitate 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 two 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 arranged at intervals. 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 edge 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 of the partition 120 in the shape of a straight plate as a whole, 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 set to be farther 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 set to be closer to the heat exchange assembly 300. In this solution, no matter how the distance between the air supply assembly 200 and the heat exchange assembly 300 changes, the opening 1222 of the second plate 122 can match the position change of the air supply assembly 200, so 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 in the air handling unit 10. For example, when the partition is matched with the water receiving tray in the initial product, 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 modification cost when adjusting 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 formed by bending a flat sheet metal, and the first side 1211 and the second side 1212 are the bending positions 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 hot melt or welding, and the first plate 121 and the third plate 123 can also be connected by hot melt 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 corner transitions. Figure 7 In this embodiment, there is a rounded transition between the first plate body 121 and the second plate body 122 , and there is a rounded transition between the first plate body 121 and the third plate body 123 .

[0100] The first side 1211 and the second side 1212 may be arranged in parallel, or the first side 1211 and the second side 1212 may be arranged crosswise. In some embodiments, when the air supply assembly 200 only translates along the first direction X during the product modification process, the first side 1211 and the second side 1212 may be arranged in parallel. In other embodiments, when the air supply assembly 200 translates along the first direction X and deflects in a direction perpendicular to the first direction X during the product modification process, the first side 1211 and the second side 1212 may be arranged crosswise, and this solution can further adapt to the position change 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 exported by 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 exported by 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 suitable for connecting to the shell 110, the side wing plate 124 extends along the first direction X, and the side wing plate 124 is located on one side of the first plate body 121 along the third direction Z, and herein, the direction parallel to the first side edge 1211 is defined as the third direction Z. The side wing plate 124 connects at least one of the first plate body 121, the second plate body 122, and the third plate body 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 body 122 along the third direction Z and both sides of the third plate body 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 body 121 along the third direction Z. The side wing plates 124 may be integrally bent and formed by a bending process, and the side wing plates 124 can increase the contact area between the shell 110, thereby improving the connection stability between the partition 120 and the shell 110. In other embodiments, the side wing plate 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 plate 124 is provided at the periphery 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, and the side wing plate 124 is threadedly connected to the housing 110 through the threaded through hole. The plate body of the housing 110 can also be provided with a buckle 1111 that tilts inward, and the side wing plate 124 is sandwiched between the buckle 1111 and the plate body to be snap-connected with the housing 110. In other embodiments, the side wing plate 124 can also be glued or welded to the housing 110.

The back plate 113 and the side plate 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 set of multiple plates spliced ​​together, or a plate integrally connected to the back plate 113 and / or the side plate 114 of the housing 110. See Figure 3In this embodiment, the upper plate 111 is integrally connected with 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 set of multiple plates, or a plate integrally connected with 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 fence-shaped 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 junction of the two sub-plates of the lower plate 112. In this embodiment, the air inlet 118 is disposed on the lower plate 112 . In other embodiments, the air inlet 118 may also be disposed 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, the airflow outside the housing 110 enters the first chamber 115 through the air inlet 118 on the lower plate 112, and flows upward from 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, the third side 1221 of the second plate 122 is connected to the lower plate 112, and the fourth side 1231 of the third plate 123 is connected to the upper plate 111.

[0106] In some embodiments, the upper plate body 111 can also be formed by splicing two plates, namely, a first sub-plate body and a second sub-plate body. The first sub-plate body is independently provided or connected to the back plate 113 as a whole, and the second sub-plate body is formed as a whole with the partition 120 (specifically, it can be bent into shape). Specifically, the side of the second sub-plate body abutting against 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 as a whole. 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 formed as a whole (specifically, it can be bent into shape). Specifically, the side of the first sub-plate body abutting against the second sub-plate body is connected to the partition 120 as a whole, and the other opposite side can be connected to the back plate 113 as a whole. At this time, the first sub-plate body, the partition 120 and the back plate 113 form an overall 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 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 Fig.14 In some embodiments, along the first direction X, the second plate 122 may 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 component 200 (i.e., the second plate 122) is offset in the direction away from the heat exchange component 300, thereby adapting to the position change of the air supply component 200. When the air supply component 200 in the modified product moves toward the heat exchange component 300, see Fig.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, that is, relative to the straight plate-shaped partition before the modification, the side of the modified partition 120 close to the air supply component 200 (i.e., the second plate 122) is offset toward the direction close to the heat exchange component 300, thereby adapting to the position change of the air supply component 200. In the case where the air supply component 200 in the modified product is deflected compared to the original product, the second plate 122 can also be deflected compared 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 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. Fig.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 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 requirements for the bending performance of the partition 120. When the partition 120 is integrally injection-molded by an injection molded part, the small bending angle can facilitate demolding, reducing the difficulty of processing 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 may 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 may be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85° or 89°, etc. 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 facing the third plate 123. In this solution, the bending angle between the first plate 121 and the second plate 122 is larger, the bending angle between the first plate 121 and the third plate 123 is larger, and when viewed along the first direction X, the first plate 121 is located in the overlapping area of ​​the second plate 122 and the third plate 123. In this solution, the partition 120 is elastic as a whole, and the second plate 122 and the third plate 123 can be close to or away from each other in a small range, which can compensate for processing errors or assembly errors. When the distance between the second plate 122 and the third plate 123 is too small or too large, the processing error or assembly error can be compensated by stretching or compressing the distance between the second plate 122 and the third plate 123. Specifically, in this embodiment, the angle between the direction from the first side 1211 to the second side 1212 and the first direction X may 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 may be 91°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130° or 135°, etc. Fig.17 The thickness directions of the second plate body 122 and the fourth plate body may also be arranged to intersect with the first direction X.

[0109] The arrangement position 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 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 second plate 122 is parallel to the horizontal direction, that is, the second plate 122 is arranged vertically. This solution is more convenient for the second plate 122 to be connected to the housing 110. It should be noted that the "substantially" and "basically" described in this document when defining data or orientations both indicate that the error range is within 10%. For example, "the direction from the first side 1211 to the third side 1221 is substantially 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 body 122 may also be arranged obliquely, that is, the direction from the first side edge 1211 to the third side edge 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 Figure 1-Figure 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 a shell assembly 100, an air supply assembly 200, and a heat exchange assembly 300 according to any one of the above items.

[0111] The air supply assembly 200 is disposed in the first chamber 115 in 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 Fig.10 , the air supply assembly 200 is a turbofan assembly, and the air supply assembly 200 includes one or more drive motors 210, one or more volutes 220, and the number of wind wheels 230 is the same as the number of volutes 220, and each wind wheel 230 is arranged in each volute 220 in a one-to-one correspondence. Specifically, in this embodiment, the air supply assembly 200 includes two drive motors 210, four volutes 220, and four wind wheels 230, and each drive motor 210 drives the wind wheels 230 located on both sides thereof along the third direction Z. The air supply assembly 200 also includes a drive shaft connected to each wind wheel 230, which is respectively arranged in each volute 220 and 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 in the corresponding volute 220, thereby sucking the 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, each volute 220 is arranged at intervals along the third direction Z. The partition 120 has the same number of openings 1222 as the number of volutes 220. Each opening 1222 is arranged at intervals along the third direction Z. Each volute 220 delivers 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 airflow transmitted by the heat exchange airflow, and the heated or cooled air is transmitted to the outside 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 receiving pan 400 disposed in the second chamber 116. The water receiving pan 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 receiving pan 400 can only store condensed water and remove the received condensed water by evaporation. The water receiving pan 400 can also be provided with a water outlet. After receiving the condensed water, the water receiving pan 400 discharges the condensed water through the water outlet. In this embodiment, the wall surface of the third plate body 123 facing away from the first chamber 115 abuts against the water receiving pan 400. In this solution, the water receiving pan 400 is used to locate 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, 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 an end of the first step wall 12321 close to the first chamber 115. The water receiving tray 400 includes an abutting end 410 abutting against the partition 120, and the first step wall 12321 abuts against the upper wall surface of the abutting end 410, thereby defining the height position of the partition 120; the second step wall 12322 abuts against 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 setting the two wall surfaces of the step portion 1232 to abut against the two wall surfaces of the abutting end 410, the water receiving tray 400 can simultaneously position the vertical position and the horizontal position of the partition 120, and the positioning effect is better. In other embodiments, in order to achieve the positioning of the partition 120, the end of the water receiving tray 400 close to the air supply assembly 200 may be provided with a vertically arranged through hole, and the fourth side 1231 of the third plate body 123 is penetrated through the through hole of the water receiving tray 400 so as to be 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 all in contact with the inner wall of the through hole, and the positioning effect is better. In addition to the fourth side 1231 being penetrated in the through hole as a whole, in another embodiment, the fourth side 1231 can also be partially penetrated in the through hole. Specifically, the fourth side 1231 of the third plate body 123 is provided with a protruding structure, and the protruding structure is penetrated through the through hole of the water receiving tray 400. 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 docking water 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 end of 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 thereon 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 installation of the water receiving tray 400 is completed, 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] Furthermore, 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 there is no need to adjust the matching structure between the water receiving tray 400 and the partition 120 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 the product modification process, when the relative distance between the air supply component 200 and the heat exchange component 300 changes, the airflow generated by the air supply component 200 will theoretically change the relative coverage area of ​​the heat exchange component 300. For example, when the relative position between the air supply component 200 and the heat exchange component 300 becomes farther, the airflow derived from the air supply component 200 is divergent, so that the flow obtained by the heat exchange component 300 is reduced. When the relative position between the air supply component 200 and the heat exchange component 300 becomes closer, the flow obtained by the heat exchange component 300 remains unchanged, but the flow density of the airflow obtained by a part of the heat exchange component 300 will increase, and the flow density of the airflow obtained by another part will decrease. In any of the above situations, the heat exchange efficiency of the heat exchange component 300 will be reduced. Therefore, in order to ensure that the airflow generated by the air supply component 200 in the modified product can efficiently exchange heat with the heat exchange component 300, it is also necessary to adjust the shape of the heat exchange component 300, or adjust the outlet angle of the air outlet 119 of the air supply component 200, so that the airflow sent by the air supply component 200 can basically cover the heat exchange component 300, so as to avoid the airflow directed to the heat exchange component 300 by the air supply component 200 not covering the heat exchange component 300, thereby reducing the heat exchange efficiency of the heat exchange component 300, or the airflow coverage area directed to the heat exchange component 300 by the air supply component 200 is much larger than the windward area of ​​the heat exchange component 300, thereby reducing the heat exchange efficiency of the heat exchange component 300. However, adjusting the shape of the air supply component 200 will increase the modification cost.

[0116] In view of this, in order to further reduce the cost of modification, see Figure 7-Figure 12In 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 volute tongue 222 and other parts of the volute 220 for guiding the airflow), and 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 a variety of fixing methods. In some embodiments, the air outlet 221 is penetrated through the opening 1222, and the first guide plate 130a is connected to the port edge of the air outlet 221. The first guide plate 130a can adjust the air outlet direction or air outlet 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 releases 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 221. Specifically, the first guide plate 130a may be disposed in the second chamber 116 and connected to the outer peripheral 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. In addition, in this solution, the air outlet 221 may be provided through the opening 1222 of the partition 120, or may not be provided through the opening 1222 of the partition 120. Since the first guide plate 130a is not connected to the air outlet 221, there is no need to set a connection structure with the first guide plate 130a on the air outlet 221, so that the appearance of the air supply assembly 200 in the modified product can basically follow the appearance before the modification, further reducing the modification cost.

[0119] In order to improve the flow guiding effect, in some embodiments, the air handling unit 10 may include a plurality of first flow guide plates 130a. In order to distinguish the flow guide plates, two of the flow guide plates are used as an example for description, and the two flow guide plates are named as the first flow guide plate 130a and the second flow guide plate 130b, respectively. The first flow guide plate 130a may be located below the axis of the opening 1222, and the second flow guide plate 130b may be located above the axis of the opening 1222. Along the first direction X, the first flow guide plate 130a is arranged to tilt downward, and under the guidance of the first flow guide plate 130a, a part of the airflow out of the opening 1222 of the partition plate 120 diverges downward. Along the first direction X, the second flow guide plate 130b is arranged horizontally, and under the guidance of the second flow guide plate 130b, a part of the airflow out of the opening 1222 of the partition plate 120 is horizontally discharged. In this solution, the distance between the opening 1222 and the heat exchange assembly 300 can be adapted by adjusting the inclination angle of the first guide plate 130a, so that the airflow is completely directed to all parts of the heat exchange assembly 300 as much as possible, thereby improving the heat exchange efficiency of the heat exchange assembly 300. In other embodiments, other guide plates can be additionally 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 plate 120, since there is an angle between the first guide plate 130a and the partition plate 120, it is difficult for the first guide plate 130a and the partition plate 120 to be relatively fixed. In order to solve the above problem, see Fig.12 In some embodiments, a side of the first guide plate 130a close to the partition plate 120 is provided with an upwardly turned flange, and the flange is attached to the side wall of the partition plate 120 away from the air supply assembly 200, and the flange can be welded, glued, screwed or riveted to the partition plate 120. The structural design of the flange can increase the attachment area with the partition plate 120, thereby improving the connection strength between the first guide plate 130a and the partition plate 120, and the design of the flange enables the guide wall surface of the first guide plate 130a to be flush with the outer periphery of the opening 1222 of the partition plate 120, thereby improving the guide effect of the first guide plate 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 away from the partition 120, and the air handling unit 10 satisfies at least one of the following conditions a)-c):

[0122] a) See Fig.11 , along the first direction X, the minimum distance L between the volute 220 and the back plate 113 1 Satisfaction: L 1≥10mm, illustratively, the minimum distance L between the volute 220 and the back plate 113 1 It can be 10mm, 11mm, 12mm or 13mm, etc. It should be noted that in this embodiment, L 1 It is defined as the minimum distance between the back plate 113 and the volute 220 when viewed along the third direction Z, that is, when the outer periphery of the back plate 113 is provided with a flange toward the air supply assembly 200, the minimum distance between the volute 220 and the back plate 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 back plate 113 meets the above requirements, the assembly of the volute 220 can be facilitated.

[0123] b) See Figure 11-Figure 12 , the minimum distance L between the wind wheel 230 and the inner wall of the volute 220 2 Satisfaction: L 2 ≥4.5 mm, illustratively, the minimum distance L between the wind wheel 230 and the inner wall of the volute 220 2 It can be 4.5 mm, 5 mm, 5.5 mm or 6 mm, etc. The minimum distance L between the wind wheel 230 and the inner wall of the volute 220 is 2 The noise of the air duct is greatly affected. Through the relevant noise and air volume test, when L 2 ≥4.5mm, which can further reduce the noise of the air supply component 200 and increase the air output of the air supply component 200.

[0124] c) See Figure 11-Figure 12 The volute 220 includes a volute tongue 222, the radius of which is r 1 The radius r of the wind wheel 230 2 Satisfaction: 0.1r 2 ≤r 1 ≤0.2r 2 For example, the radius r of the volute tongue 222 is 1 Can be 0.1r 2 , 0.12r 2 , 0.14r 2 , 0.16r 2 、0.18r 2 or 0.2r 2 In this solution, the noise of the air supply component 200 can be further reduced and the air output of the air supply component 200 can be increased.

[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 and generate 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, and the electric control box 500 is disposed inside the housing 110 and between the side panel 114 and the air supply assembly 200. In other embodiments, the electric control box 500 is disposed outside the housing 110 and on the side of the side panel 114 away from the air supply assembly 200. In still other embodiments, see Figure 1-Figure 4 , a mezzanine space 117 is provided on the side of the housing 110, and 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 electric control box 500 is arranged in the mezzanine space 117. In the above embodiment, the electric control box 500 is arranged on the left or right side (i.e., on one side of the air supply assembly 200 along the third direction Z), which can release the rear space of the first chamber 115 (i.e., the space on one side of the air supply assembly 200 away from the heat exchange assembly 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 assembly 200, and preventing the volute 220 from vibrating and hitting the electric control box 500 to generate noise.
