[0058] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0059] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0060] The air treatment device includes a housing main body, a functional module disposed within the housing main body, and a water tank for supplying water to the functional module. In the related art, the water tank is detachably connected to the housing main body, thereby facilitating the replenishment of water in the water tank. The water tank includes a first box body disposed on the front side of the functional module and a second box body inserted into the housing main body from front to back and located above the functional module. The front end of the second box body is connected to the upper end of the first box body, and the water tank can be separated from the housing main body forward.

[0061] In the related art, when it is necessary to separate the water tank, one hand needs to hold the upper end of the first box body and the other hand needs to hold the lower end of the first box body, and the two hands pull the first box body forward simultaneously, so as to realize the separation of the water tank. When operating with one hand, one end of the water tank is subjected to a pulling force, and the pulling force and the gravity of the second box body jointly act to form a bending moment, making the whole water tank tend to flip. When the water tank flips slightly, the second box body rubs against the housing main body or the functional module, thus hindering the extraction or insertion of the water tank. In summary, since a part of the water tank is inserted into the housing main body, it is rather troublesome to extract or insert the water tank into the housing main body. When removing the part of the water tank inserted into the housing main body, that is, removing the second box body of the water tank, although it is convenient for the disassembly and assembly of the water tank, on the one hand, the volume of the water tank is difficult to meet the requirements, and on the other hand, the space above the functional module is difficult to be reasonably utilized.

[0062] See Figures 1 - 13 , in an embodiment of the present invention, a housing assembly 100 is provided. The housing assembly 100 is used for an air handling unit 200, and the housing assembly 100 can communicate with a first area (specifically, it can be outdoors) located outside and a second area (specifically, it can be indoors) located outside. In some embodiments, the air handling unit 200 can make the air in the first area and the air in the second area flow through each other. In other embodiments, the housing assembly 100 can have a plurality of openings respectively communicating with the first area, and the air handling unit 200 can suck the air in the first area and make it re-enter the first area after passing through the inner cavity of the housing assembly 100. It should be noted that the outside described in the present invention refers to the area outside the structure of the housing assembly 100 itself. In different embodiments, the outside can be indoors or outdoors.

[0063] The housing assembly 100 includes a housing main body 110 and a water tank 150. Specifically, see Figures 1 - 3, the housing main body 110 includes an air duct housing 111, a first flow guide housing 130, and a second flow guide housing 120. Among them, the air duct housing 111 defines an air inlet cavity 1111 and an air outlet cavity 1112 that communicate with each other and are arranged opposite to each other in the transverse direction. The air inlet cavity 1111 is adapted to accommodate the functional module 210, and the air outlet cavity 1112 is adapted to accommodate the air supply assembly 220. In some embodiments, the inner cavity of the air duct housing 111 is formed by surrounding and extending the outer periphery of the air duct housing 111. The air inlet cavity 1111 and the air outlet cavity 1112 are respectively two parts of the inner cavity of the air duct housing 111, so there may be no gap between them; according to requirements, in other embodiments, a partition structure (such as a partition) may be provided between the air inlet cavity 1111 and the air outlet cavity 1112 to partially separate the air inlet cavity 1111 and the air outlet cavity 1112. After the functional module 210 is disposed in the air inlet cavity 1111, the functional module 210 can process the airflow passing through the air inlet cavity 1111. For example, in some embodiments, the functional module 210 can perform at least one of the functions of humidifying, dehumidifying, heating, cooling, removing formaldehyde, deodorizing, and dust removing on the airflow. Based on the settings of the air inlet cavity 1111 and the air outlet cavity 1112, in order to play various guiding roles, the first flow guide housing 130 communicates with the air outlet cavity 1112, and the second flow guide housing 120 communicates with the air inlet cavity 1111.

[0064] The first flow guide housing 130 is used to guide the airflow in the air outlet cavity 1112 of the air duct housing 111. The first flow guide housing 130 can be detachably connected to the air duct housing 111 or integrally connected to the air duct housing 111. When the first flow guide housing 130 is detachably connected to the air duct housing 111, after the two are disassembled from each other, the part with the air outlet 131 is the first flow guide housing 130, and the part for accommodating the air supply assembly 220 is the air duct housing 111. When the first flow guide housing 130 is integrally connected to the air duct housing 111, the first flow guide housing 130 is a section of the housing that defines the air outlet 131 for guiding the end airflow, and along the direction parallel to the axis of the air outlet 131, the shell section projected by the air outlet 131 belongs to the first flow guide housing 130.

[0065] The second flow guide housing 120 is used to introduce airflow into the air inlet cavity 1111 of the air duct housing 111. The second flow guide housing 120 can be detachably connected to the air duct housing 111 or integrally connected to the air duct housing 111. When the second flow guide housing 120 is detachably connected to the air duct housing 111, after the two are disassembled from each other, the part with the first air inlet 122 is the second flow guide housing 120, and the part for accommodating the functional module 210 is the air duct housing 111. When the second flow guide housing 120 is integrally connected to the air duct housing 111, the second flow guide housing 120 is a section of the housing for guiding the front-end airflow entering the first air inlet 122, and along the direction parallel to the axis of the first air inlet 122, the shell section projected by the first air inlet 122 belongs to the second flow guide housing 120.

[0066] Refer to Figures 1 - 4 , the water tank 150 is detachably connected to the housing main body 110. When observed from top to bottom, a part of the water tank 150 is located on the front side of the air inlet cavity 1111 and a part is located on the front side of the air outlet cavity 1112. The specific form of the detachable connection between the water tank 150 and the housing main body 110 can be sliding connection, snap connection, magnetic connection, etc. The above settings enable the efficient utilization of the front side spaces of both the air inlet cavity 1111 and the air outlet cavity 1112. Setting the water tank 150 on the side part of the housing main body 110 can also make it more convenient for users to operate and disassemble the water tank 150. The water tank 150 is suitable for collecting the water exported by the functional module 210; at the same time, the water tank 150 can also be suitable for supplying water to the functional module 210. More specifically, in some embodiments, the functional module 210 may include a wet film, and the water tank 150 (or the water delivery structure cooperating with the water tank 150) can drip water above the wet film. The wet film that obtains moisture can humidify the air flow passing through the wet film. At the same time, the housing main body 110 may further include a water storage tank 141, and the water will pass through the wet film from top to bottom and enter the water storage tank 141. The water stored in the water storage tank 141 can be further pumped into the water tank 150. In addition, in some other embodiments, the water passing through the wet film can directly enter the water tank 150. It should be noted that the water described in the present invention can be any suitable type of liquid. According to requirements, the water tank 150 can be suitable for accommodating and transporting various types of liquids, such as tap water, coolant, etc.

[0067] Refer to Figure 1 , when observed from front to back, both the first diversion shell 130 and the second diversion shell 120 are at least partially located above the water tank 150. The above settings enable the full utilization of the space above the water tank 150. In some embodiments, when observed from front to back, both the first diversion shell 130 and the second diversion shell 120 may be completely located above the water tank 150; in contrast, in some other embodiments, the first diversion shell 130 and / or the second diversion shell 120 may have a height overlap with the water tank 150, that is, when observed from front to back, a part of the first diversion shell 130 and / or the second diversion shell 120 may overlap with the water tank 150 and another part may be higher than the water tank 150.

[0068] In the technical solution of the present utility model, the housing assembly 100 includes a housing main body 110 and a water tank 150. The housing main body 110 includes an air duct housing 111, a first diversion housing 130 connected to the air duct housing 111, and a second diversion housing 120. The water tank 150 is detachably connected to the housing main body 110. When observed from top to bottom, one side of the water tank 150 is located in front of the air inlet chamber 1111, and the other side is located in front of the air outlet chamber 1112. In other words, in this solution, on the one hand, the part of the water tank 150 inserted into the housing main body 110 is removed; on the other hand, the water tank 150 extends horizontally so that a part of it is located in front of the air outlet chamber 1112, that is, the part of the water tank 150 located in front of the air outlet chamber 1112 is increased to replace the removed part inserted into the housing main body 110, so that the overall volume of the water tank 150 does not change much. While ensuring the volume of the water tank 150, it facilitates the disassembly and assembly of the water tank 150. Moreover, in this solution, when observed from front to back, at least part of the first diversion housing 130 is located above the water tank 150, that is, the first diversion housing 130 can reasonably utilize the space of the part originally removed from the water tank 150, so as to facilitate the layout of the position of the first diversion housing 130 without increasing the overall external dimensions of the housing assembly 100. More specifically, when observed from front to back, at least part of the second diversion housing 120 is located above the water tank 150, that is, the second diversion housing 120 utilizes the space beside the first diversion housing 130. Compared with the solution where the second diversion housing 120 is located on the back side or other sides of the housing main body 110, the overall occupied space of the housing assembly 100 is smaller. In summary, this solution makes the space layout of the air handling unit 200 with the housing assembly 100 more reasonable while facilitating the separation of the water tank 150 and meeting the volume requirements of the water tank 150.

[0069] See Figure 3 , when observed from top to bottom, at least part of the first diversion housing 130 coincides with the water tank 150. In other words, the figure enclosed by the orthographic projection of the first diversion housing 130 on the projection plane perpendicular to the vertical direction and the figure enclosed by the orthographic projection of the water tank 150 on the above projection plane may have an overlapping part. It can be understood that since part of the water tank 150 is located in front of the air inlet chamber 1111 and part is located in front of the air outlet chamber 1112, the height of the water tank 150 can be the same as or close to the height of the housing main body 110. Thus, one end of the first diversion housing 130 arranged above the water tank 150 can be connected to the housing main body 110 and communicate with the air outlet chamber 1112, and the other end of the first diversion housing 130 can extend horizontally above the water tank 150, so that at least part of the first diversion housing 130 coincides with the water tank 150. The above arrangement can make full use of the upper space of the housing main body 110 and the upper space of the water tank 150 to arrange the first diversion housing 130, which is conducive to increasing the design volume of the first diversion housing 130 and the outflow area of the air outlet 131 of the first diversion housing 130.

[0070] Furthermore, to make the water tank 150 easier to disassemble and assemble. In some embodiments, the upper end of the water tank 150 is spaced from the first diversion shell 130. The above setting prevents the first diversion shell 130 from hindering the disassembly and assembly operation of the water tank 150. In other embodiments, the upper end of the water tank 150 is detachably connected to the first diversion shell 130. Through the detachable connection between the water tank 150 and the first diversion shell 130, the integrity and tightness of the housing assembly 100 are enhanced, which is beneficial to increasing the design size of the first diversion shell 130. At the same time, the water tank 150 can be detached separately relative to the first diversion shell 130.

[0071] Regarding the specific setting of the diversion shell, on the one hand, see Figures 1 - 2 , in some embodiments, the first diversion shell 130 is provided with an air outlet 131 communicating with the air outlet cavity 1112, and the air outlet 131 discharges air forward. The following is the definition of the air outlet 131 discharging air forward: Under the driving action, the air flow located in the air outlet cavity 1112 can flow from the rear to the front and pass through the air outlet 131 to reach the outside. Therefore, the air outlet 131 discharging air forward is not limited to a single air outlet direction. By arranging the first diversion shell 130 above the water tank 150 and setting the air outlet 131 to discharge air forward, the position and orientation of the air outlet 131 can be made more reasonable, and it is beneficial to save space.

[0072] On the other hand, see Figures 1 - 2 , in some embodiments, the second diversion shell 120 is provided with a first air inlet 122 communicating with the air inlet cavity 1111, and the first air inlet 122 takes in air from the rear. The following is the definition of the first air inlet 122 taking in air from the rear: Under the driving action, the air flow located outside can flow from the rear to the front and pass through the first air inlet 122 to reach the air inlet cavity 1111. Therefore, the first air inlet 122 taking in air from the rear is not limited to a single air inlet direction. By arranging the second diversion shell 120 above the water tank 150 and setting the first air inlet 122 to take in air from the rear, the position and orientation of the first air inlet 122 can be made more reasonable, and it is beneficial to save space.

[0073] It can be understood that the above embodiments for the setting of the first air inlet 122 are similar to the setting of the air outlet 131, and the difference is that the two settings correspond to the air outlet demand and the air inlet demand respectively. See Figures 1 - 2, in some embodiments, the settings of both aspects can be adopted simultaneously, that is, while the air outlet 131 blows air forward, the first air inlet 122 sucks air from the rear. The above settings make the air outlet direction opposite to the air inlet direction, so that the first flow guide shell 130 and the second flow guide shell 120 are not prone to structural interference and affect the flow area of the first air inlet 122 and the air outlet 131.

[0074] To make more full use of the space above the shell body 110, on the one hand, referring to Figure 5 , in some embodiments, when observed from the front to the back, the upper end of the first flow guide shell 130 extends horizontally to the upper end of the air inlet cavity 1111. It can be understood that the first flow guide shell 130 being located at the upper ends of both the air outlet cavity 1112 and the air inlet cavity 1111 is beneficial to increasing the design volume of the first flow guide shell 130, and at the same time can also increase the flow area of the air outlet 131, making the air outlet effect better. On the other hand, referring to Figure 5 , in some other embodiments, the first flow guide shell 130 is provided with an air outlet 131 communicating with the air outlet cavity 1112. When observed from the front to the back, a part of the air outlet 131 is located at the upper end of the air inlet cavity 1111 and a part is located at the upper end of the air outlet cavity 1112. It can be understood that the air outlet 131 being located at the upper ends of both the air outlet cavity 1112 and the air inlet cavity 1111 can increase the flow area of the air outlet 131, making the air outlet effect better. At the same time, the structure of the first flow guide shell 130 can be unrestricted, making the first flow guide shell 130 more convenient to arrange. In addition, in some other embodiments, the above settings for the first flow guide shell 130 and the air outlet 131 can be applied to the second flow guide shell 120 and the first air inlet 122 in the same way and have similar effects, which will not be elaborated here.

[0075] To make more full use of the space above the shell body 110, on the one hand, referring to Figure 3 , in some embodiments, when observed from the front to the back, the first flow guide shell 130 and the second flow guide shell 120 at least partially overlap. In other words, the figure enclosed by the orthographic projection of the first flow guide shell 130 on the projection plane perpendicular to the front-back direction and the figure enclosed by the orthographic projection of the second flow guide shell 120 on the above projection plane can have an overlapping part. It can be understood that the above limitation makes the first flow guide shell 130 and the second flow guide shell 120 arranged in an interleaved manner, thus saving the space in the left-right direction of the upper part of the shell body 110 and being beneficial to increasing the design volume of the first flow guide shell 130 and the second flow guide shell 120. On the other hand, referring to Figure 3, in some embodiments, the first air guide housing 130 is provided with an air outlet 131 communicating with the air outlet cavity 1112. When observed from the front to the back, at least a part of the air outlet 131 coincides with the second air guide housing 120. In other words, the figure formed by the positive projection of the opening edge of the air outlet 131 on the projection plane perpendicular to the front-back direction and the figure formed by the positive projection of the second air guide housing 120 on the above projection plane may have an overlapping part. It can be understood that the above limitation makes the air outlet 131 and the second air guide housing 120 arranged in an interleaved manner, thus saving the space in the left-right direction of the upper part of the housing main body 110, which is beneficial to increasing the size of the air outlet 131 so that the outflow area of the air outlet 131 is larger.

[0076] To play a better positioning role for the water tank 150, refer to Figures 1 - 2 , in some embodiments, the air duct housing 111 includes a first front wall plate 1114 located on the front side of the air outlet cavity 1112, and the first front wall plate 1114 is provided with a convex portion 1118 protruding towards the water tank 150. A concave portion 151 is provided on the side of the water tank 150 facing the convex portion 1118, and the convex portion 1118 extends into the concave portion 151. Among them, the front side of the air outlet cavity 1112 corresponds to the side of the air outlet cavity 1112 facing the water tank 150. Therefore, the first front wall plate 1114 is provided at this place, and the convex portion 1118 of the first front wall plate 1114 and the concave portion 151 of the water tank 150 cooperate with each other, which can limit the position of the water tank 150 in the left-right direction, make the water tank 150 not easy to shake, and the installation is more stable. The convex portion 1118 and the concave portion 151 can both be of any suitable structural shape, such as a rectangle, an irregular figure, etc. At the same time, in different embodiments, the cooperation between the convex portion 1118 and the concave portion 151 can be a clearance fit or an interference fit. In addition, in some other embodiments, the first front wall plate 1114 can be provided with a concave structure, and the water tank 150 can be provided with a convex structure. The above convex structure extends into the groove structure, and the same effect as the setting of the foregoing embodiments can also be achieved.

[0077] Based on the convex portion 1118 and the concave portion 151 provided in the above embodiments, further, refer to Figures 1 - 2, in some embodiments, a concave cavity communicating with the air outlet cavity 1112 is formed on the side of the convex portion 1118 facing the air outlet cavity 1112, and the concave cavity is adapted to accommodate at least a part of the air supply assembly 220. It can be understood that the above arrangement enables the convex portion 1118 to define a concave cavity on the side close to the air outlet cavity 1112 while protruding towards the water tank 150, and this concave cavity can be used to accommodate the air supply assembly 220 (specifically, it can accommodate the fan blade 221 of the air supply assembly 220 or the fan housing wrapping the fan blade 221). Thus, the setting of the concave cavity is beneficial to increasing the design size of the air supply assembly 220, and further beneficial to increasing the air supply efficiency of the air supply assembly 220. Correspondingly, in some other embodiments, the convex portion 1118 can be a solid convex block structure, so that no groove is formed on the side of the convex portion 1118 close to the air outlet cavity 1112 in the front-rear direction, and this setting is beneficial to improving the overall structural strength of the convex portion 1118 and the air duct housing 111.

[0078] To make the functional module 210 easier to disassemble and assemble, refer to Figure 5 , in some embodiments, the air duct housing 111 includes a second front wall plate 1115 located on the front side of the air inlet cavity 1111. The second front wall plate 1115 is provided with an assembly opening for disassembling and assembling the functional module 210, and the water tank 150 covers the assembly opening. It can be understood that by providing the above-mentioned assembly opening, after removing the water tank 150, the user can take and place the functional module 210 in the front-rear direction. At the same time, after the water tank 150 is installed on the housing main body 110, it can cover the assembly opening, which can reduce the influence of the assembly opening being exposed to the outside on the functional module 210, and make the overall housing assembly 100 more beautiful and tidy. More specifically, the shape of the assembly opening can be determined according to the specific structure of the functional module 210. When the number of functional modules 210 is multiple, in some embodiments, the number of assembly openings is also multiple, and each assembly opening is arranged in one-to-one correspondence with each functional module 210; in some other embodiments, the number of assembly openings can be at least one, and one assembly opening can correspond to taking and placing multiple functional modules 210.

[0079] To make it more convenient to supply water to the water tank 150, refer to Figure 5, in some embodiments, a retaining edge 140 is provided at the lower end of the front side of the air duct housing 111. The retaining edge 140 is provided with a water tank 141 communicating with the air inlet chamber 1111. The water tank 141 is adapted to collect the water falling from the functional module 210. The water tank 150 is detachably connected above the retaining edge 140, and the inner cavity of the water tank 150 communicates with the water tank 141. The specific form of the detachable connection of the water tank 150 to the retaining edge 140 can be a sliding connection, a snap connection, a magnetic connection, etc. It can be understood that the retaining edge 140 can be located on the lower side of the air duct housing 111 and can receive the water falling through the functional module 210 to play a role in collecting water. At the same time, on the one hand, the water tank 141 can support and connect the water tank 150 to make the installation of the water tank 150 more stable. On the other hand, the water tank 141 can also supply water to the water tank 150. Specifically, a water pump can be arranged in the water tank 141 or the water tank 150, and a pipeline can be connected to the water pump so that the water collected by the water tank 141 can be re-supplied to the water tank 150 to realize water circulation. In some embodiments, the water tank 141 is detachably connected to the main body part of the air duct housing 111 to facilitate the user to operate on the water tank 141; in other embodiments, the water tank 141 and the main body part of the air duct housing 111 are integrally connected to improve the structural integrity of the air duct housing 111.

[0080] The functional module 210 may include a first functional module 210A. In order to make the space utilization rate of the air inlet chamber 1111 higher, it is convenient to install the first functional module 210A. Refer to Figures 6 - 10, in the first installation method of the functional module 210, the air duct housing 111 is provided with a first opening 112 communicating with the air inlet cavity 1111. The second diversion housing 120 defines a diversion channel 300. One end of the diversion channel 300 communicates with the first opening 112, and the other end is provided with a first air inlet 122. The air duct housing 111 is provided with a first installation structure 113 extending into the first opening 112 at the first opening 112. The first installation structure 113 is adapted to install the first functional module 210A. In some embodiments, the first installation structure 113 may be connected to the peripheral wall surface for defining the first opening 112 and extend into the first opening 112. In other embodiments, the first installation structure 113 may be connected to the inner wall surface of the air duct housing 111 facing the air inlet cavity 1111 and extend in a direction close to the first opening 112 to cover a part of the first opening 112. One end of the diversion channel 300 is provided with a second opening 121 communicating with the first opening 112, and the other end is provided with a first air inlet 122 communicating with the outside. It can be understood that the diversion channel 300 can allow air flow. Specifically, it can be used to convey the gas in the air inlet cavity 1111 to the outside, or to convey the outside gas to the air inlet cavity 1111. According to requirements, the second diversion housing 120 can have any suitable structural shape, and the diversion channel 300 can be a straight channel or a curved channel. In some embodiments, an adjustment baffle 123 may be provided at the first air inlet 122 to adjust the outflow area of the first air inlet 122 according to requirements.

[0081] In this embodiment, an installation structure for installing the first functional module 210A is arranged near the junction position between the second diversion housing 120 and the air duct housing 111, making full use of the opening space at the connection position between the second diversion housing 120 and the air duct housing 111, so that the layout space of the first functional module 210A is more sufficient, and the internal space utilization rate of the air handling unit 200 having the housing assembly 100 is improved. Moreover, since this solution does not reduce the channel size of the diversion channel 300 of the original second diversion housing 120, the setting of the first installation structure 113 or the second installation structure 118 has a relatively small impact on the diversion flow of the second diversion housing 120. Compared with the solution of reducing the size of the first opening 112 and reducing the pipe diameter of the second diversion housing 120 to make the two structures match, it has better diversion performance.

[0082] The second flow guide housing 120 and the air duct housing 111 can be integrally provided. At this time, since both the first mounting structure 113 and the second mounting structure 118 are located inside the housing assembly 100, the processing difficulty is high. In order to facilitate the processing of the first mounting structure 113 and / or the second mounting structure 118, the 3D printing method can be used to process the structure of the connecting part between the second flow guide housing 120 and the air duct housing 111 of the housing assembly 100. Preferably, in some embodiments, in order to mass-produce and form the first mounting structure 113 and / or the second mounting structure 118, the second flow guide housing 120 and the air duct housing 111 can be separately formed and then assembled and connected to each other (that is, a structure different from the integral forming connection in the existing solution), thereby reducing the processing difficulty of the first connection structure and / or the second connection structure. In particular, after the second flow guide housing 120 and the air duct housing 111 are separately processed, the two can be detachably connected or non-detachably connected. When the second flow guide housing 120 and the air duct housing 111 are detachably connected, the two can be threadedly connected, snap-connected or magnetically connected, etc.; when the second flow guide housing 120 and the air duct housing 111 are non-detachably connected, the two can be integrally connected, glued, welded or riveted, etc.

[0083] To facilitate the connection between the second flow guide housing 120 and the air duct housing 111, refer to Figures 6 - 7 , in some embodiments, an annular flange 114 is provided on the outer wall of the air duct housing 111. When observed along the axis of the first opening 112, the annular flange 114 is arranged around the outside of the first opening 112, and the second flow guide housing 120 is connected to the annular flange 114. It should be noted that when observed along the axis of the first opening 112, the annular flange 114 can be in any shape, such as any one of a circle, an ellipse, a rectangle, and an irregular shape. Through the setting of the annular flange 114, when the second flow guide housing 120 and the air duct housing 111 are detachably connected, it can facilitate the installation or positioning of the two. When the second flow guide housing 120 and the air duct housing 111 are non-detachably connected, the annular flange 114 can facilitate the positioning during the connection of the two or can enhance the connection stability between the two.

[0084] Based on the annular flange 114 provided in the above embodiment, more specifically, refer to Figures 6 - 7 , and Figures 8 - 10, in some embodiments, the second flow guide housing 120 has an annular end wall 124 facing the annular flange 114. The annular end wall 124 abuts against the end wall of the annular flange 114 facing away from the air inlet chamber 1111. The annular end wall 124 is convexly provided with an annular protrusion 1241 extending towards the first opening 112, and the annular protrusion 1241 is located inside the annular flange 114. It can be understood that, on the one hand, the abutting and mating function between the annular end wall 124 and the end wall of the annular flange 114 enables the annular flange 114 to support the second flow guide housing 120 and provides positioning and limiting effects for the second flow guide housing 120 along the axial direction of the first opening 112. On the other hand, the annular protrusion 1241 convexly formed on the annular end wall 124 is disposed opposite to the annular flange 114 along the radial direction of the first opening 112, and the annular protrusion 1241 is located inside the annular flange 114. This setting can provide positioning and limiting effects for the second flow guide housing 120 along the axial direction of the first opening 112. In addition, the annular protrusion 1241 can be spaced from the inner side of the annular flange 114 or can be in contact with the inner side of the annular flange 114.

[0085] See Figures 6 - 7 , for the specific connection form between the second flow guide housing 120 and the air duct housing 111, based on the annular flange 114 defined in the above embodiments, in one type of setting, a first snap structure 115 is provided on the outer side of the annular flange 114, and the second flow guide housing 120 includes a second snap structure 125. The first snap structure 115 is snap-connected to the second snap structure 125. In another type of setting, a first threaded connection structure 116 is provided on the outer side of the annular flange 114, and the second flow guide housing 120 includes a second threaded connection structure 126. The first threaded connection structure 116 is threadedly connected to the second threaded connection structure 126. In yet another type of setting, a first snap structure 115 and a first threaded connection structure 116 are provided on the outer side of the annular flange 114, and the second flow guide housing 120 includes a second snap structure 125 and a second threaded connection structure 126. The first snap structure 115 is snap-connected to the second snap structure 125, and at the same time, the first threaded connection structure 116 is threadedly connected to the second threaded connection structure 126. It should be noted that the outer side of the annular flange 114 described in the above embodiments can be the outer wall of the annular flange 114 or the wall surface located around the outer side of the annular flange 114.

[0086] More specifically, the threaded connection can specifically be the mating connection between a screw and a threaded hole, or a bolt connection. Exemplarily, the first threaded connection structure 116 can be provided with a threaded hole, and the second threaded connection structure 126 can be provided with a mounting hole (the mounting hole can be a clearance hole). The screw mates with the threaded hole and abuts against the periphery of the mounting hole to form a threaded connection between the air duct housing 111 and the second flow guiding housing 120. The snap connection can specifically be the mating connection between a snap groove and a snap protrusion. The two can rely on the elastic deformation of the snap groove and / or the snap protrusion when subjected to an external force to achieve disassembly and assembly. When both the threaded connection and the snap connection are used between the air duct housing 111 and the second flow guiding housing 120, the connection between the two can be made more stable and reliable. More specifically, in some embodiments, when observed along the axis direction of the first opening 112, both the air duct housing 111 and the second flow guiding housing 120 can be provided with four mounting positions (in other embodiments, it can be other numbers). Along the direction of surrounding the axis of the first opening 112, the mounting forms of every two adjacent mounting positions are different. For example, the four mounting positions can be diagonally distributed, and the mounting methods of the two diagonally arranged mounting positions are the same. For example, two of the diagonally arranged mounting positions can both be threaded connections; the other two diagonally arranged mounting positions can both be snap connections.

[0087] Further, based on the annular flange 114 defined in the above embodiment, refer to Figures 8 - 10 , in some embodiments, when observed along the axis direction of the first opening 112, the first mounting structure 113 is located inside the annular flange 114. It can be understood that in this embodiment, when observed along the axis direction of the first opening 112, the entire first mounting structure 113 is located inside the annular flange 114, so that the opening space of the first opening 112 can be utilized more fully, making the layout space of the first functional module 210A more sufficient and the space utilization rate higher. In contrast, in some other embodiments, when observed along the axis direction of the first opening 112, a part of the first mounting structure 113 is located inside the annular flange 114, and another part is located outside the annular flange 114.

[0088] To enable the first mounting structure 113 to have the function of guiding air flow, refer to Figure 10, in some embodiments, the first mounting structure 113 has a flow guiding wall surface 1131 facing the flow guiding channel 300. The flow guiding wall surface 1131 has a first side edge 11311 near the edge of the first opening 112 and a second side edge 11312 located inside the first opening 112. It can be understood that the first side edge 11311 is located at the part of the flow guiding wall surface 1131 that blocks the first opening 112, and the second side edge 11312 located inside can form one side edge of the exposed part of the first opening 112. In some embodiments, along the direction from the first side edge 11311 to the second side edge 11312, the flow guiding wall surface 1131 gradually extends away from the second flow guiding shell 120. The inclined and extended flow guiding wall surface 1131 can guide the air flow in the flow guiding channel 300 to the air inlet cavity 1111.

[0089] Further, referring to Figure 9 , in some embodiments, the air duct housing 111 further includes a blower mounting structure located in the air inlet cavity 1111. The blower mounting structure is adapted to mount the blower assembly 220. The structural form and mounting form of the blower mounting structure can be the same as or similar to those of the first mounting structure 113, or the structural form between the blower mounting structure and the first mounting structure 113 can be different according to the blower assembly 220 to be mounted. The blower assembly 220 can be used to drive the external air flow into the air inlet cavity 1111 through the first opening 112, and enable the air flow to pass through each first functional module 210A during this process. On the contrary, the blower assembly 220 can also drive the air flow in the air inlet cavity 1111 to pass through each first functional module 210A, and then pass through the first opening 112 and be introduced into the flow guiding channel 300. Referring to Figure 9 , in some embodiments, the air duct housing 111 further includes a plate body 117. The blower mounting structure and the plate body 117 are arranged opposite to each other along the direction parallel to the rotation axis. Based on the blower mounting structure and the blower assembly 220 defined in the above embodiments, along the direction from the first side edge 11311 to the second side edge 11312, the flow guiding wall surface 1131 gradually extends away from the second flow guiding shell 120 and points to the plate body 117. It can be understood that along the direction parallel to the rotation axis, the flow guiding wall surface 1131 can also guide the air flow to the plate body 117. The above air guiding setting can prevent the air flow introduced into the air inlet cavity 1111 through the first opening 112 from directly blowing onto the first functional module 210A, making the action effect of the first functional module 210A on the air flow more uniform and with a better effect.

[0090] For the specific setting position of the first opening 112, referring to Figure 9, in some embodiments, the air duct housing 111 further includes an outer wall that surrounds and forms an air inlet cavity 1111. The outer wall and the first mounting structure 113 together define a first opening 112. It can be understood that the outer wall is the outer side wall of the air duct housing 111, and by using the structure of the outer wall, it can be arranged at a relative interval with the first mounting structure 113 to define the first opening 112. The above arrangement eliminates the need to additionally provide other structures to define the first opening 112, thereby making the structure of the air duct housing 111 more concise and the manufacturing cost lower. More specifically, in some embodiments, the first opening 112 is located on the upper side of the air duct housing 111. At this time, the first mounting structure 113 can serve as the top plate of the air duct housing 111, and the circumferentially extending side walls of the outer wall and the first mounting structure 113 located on the upper side of the air duct housing 111 can jointly enclose the first opening 112. Combining the definition of the plate body 117 in the foregoing embodiments, in some embodiments, the plate body 117 can be a part of the outer wall of the air duct housing 111 and can be used to define the first opening 112.

[0091] See Figure 10 , in some embodiments, on the side of the first mounting structure 113 facing the air inlet cavity 1111, there are provided a first engaging protrusion 1132 and a second engaging protrusion 1133. The first engaging protrusion 1132 and the second engaging protrusion 1133 are arranged at intervals and form an engaging gap 1134. The engaging gap 1134 is adapted to accommodate the side edge of the first functional module 210A, so that the first mounting structure 113 is adapted to engage with the first functional module 210A. It should be noted that when the first functional module 210A is engaged with the first mounting structure 113, the first functional module 210A and the first mounting structure 113 may be in contact or at an interval. More specifically, in one installation method, the first engaging protrusion 1132 and the second engaging protrusion 1133 can jointly define an installation groove, so that the first functional module 210A can be installed by sliding connection with the installation groove; in another installation method, the first engaging protrusion 1132 and the second engaging protrusion 1133 can only be protrusion structures and play a role of abutting and limiting the first functional module 210A.

[0092] In addition, in some other embodiments, on the side of the first mounting structure 113 facing the air inlet cavity 1111, only the first engaging protrusion 1132 may be provided. Thus, in one installation method, the first engaging protrusion 1132 can cooperate with the first functional module 210A (for example, the first engaging protrusion 1132 can extend into the groove of the first functional module 210A to form a cooperation) to install the first functional module 210A; in another installation method, the first engaging protrusion 1132 can cooperate with other mounting structures of the air duct housing 111 to install the first functional module 210A.

[0093] Furthermore, the air duct housing 111 may be provided with a mounting structure suitable for mounting the first functional module 210A. Figure 9 In some embodiments, the air duct shell 111 further includes a second mounting structure 118, which is disposed on a side of the air duct shell 111 opposite to the first mounting structure 113, and the second mounting structure 118 is suitable for mounting the first functional module 210A together with the first mounting structure 113. According to the requirements, the structural shapes of the first mounting structure 113 and the second mounting structure 118 can be the same or different. In combination with the first engaging protrusion 1132, the second engaging protrusion 1133 and the engaging gap 1134 of the above-mentioned embodiment, in this embodiment, the second mounting structure 118 is provided with a third engaging protrusion and a fourth engaging protrusion on the side facing the air inlet cavity 1111, and the third engaging protrusion and the fourth engaging protrusion are arranged at intervals to form another engaging gap 1134, and along the direction from the first mounting structure 113 to the second mounting structure 118, the two side edges of the first functional module 210A are respectively accommodated in the two engaging gaps 1134, so that the installation of the first functional module 210A can be more stable and reliable.

[0094] To meet more diverse air intake requirements, see Figure 3 In some embodiments, the air duct shell 111 includes a side wall plate 1116, and the side wall plate 1116 is located on the side of the air inlet chamber 1111 away from the air outlet chamber 1112, and the side wall plate 1116 is provided with a second air inlet 1117 connected to the air inlet chamber 1111. Specifically, in some embodiments, the first air inlet 122 can be connected to a first area located outside, and the second air inlet 1117 can be connected to a second area located outside, wherein one of the first area and the second area can be indoors and the other can be outdoors. The following is an example in which the first air inlet 122 is connected to the outdoors and the second air inlet 1117 is connected to the indoors. At the same time, the air outlet 131 of the first and second guide shells 120 can be connected to the indoors. By the above arrangement, for example, see Figure 9 , Figure 12 , Figure 13, when the air handling unit 200 is in the fresh air mode, the outdoor air flow can pass through the inner cavity of the second diversion housing 120, the air inlet chamber 1111 (while passing through the first functional module 210A), the air outlet chamber 1112, and the inner cavity of the first and second diversion housing 120 in sequence from the air inlet of the second diversion housing 120, and finally be introduced into the room through the air outlet 131 of the first and second diversion housing 120; when the air handling unit 200 is in the internal circulation mode, the indoor air flow can enter the air inlet chamber 1111 through the second air inlet 1117 and pass through the first functional module 210A (the first functional module 210A can humidify and purify the passing air flow at this time), the air outlet chamber 1112, and the inner cavity of the first and second diversion housing 120 in sequence, and finally be re-introduced into the room through the air outlet 131 of the first and second diversion housing 120; when the air handling unit 200 is in the exhaust mode, the indoor air flow can enter the first and second diversion housing 120 through the air outlet 131, and pass through the air outlet chamber 1112, the air inlet chamber 1111 (while passing through the first functional module 210A), and the inner cavity of the second diversion housing 120 in sequence, and finally be discharged to the outside through the air inlet of the second diversion housing 120. In addition, according to requirements, in some other embodiments, the first air inlet 122 and the second air inlet 1117 can both communicate with the same area outside.

[0095] In addition to the first functional module 210A, when the housing assembly 100 is also suitable for installing other functional modules 210, corresponding installation structures can also be set, see Figure 9 , in some embodiments, the functional module 210 can include a second functional module 210B, and the air duct housing 111 further includes a third installation structure 119, and the third installation structure 119 is suitable for connecting the second functional module 210B. Among them, according to requirements, the installation structures formed by the first installation structure 113 and the second installation structure 118 and the installation structure formed by the third installation structure 119 can be the same or similar, or different; in addition, corresponding to the settings of the first installation structure 113, the second installation structure 118, and the third installation structure 119, the functions, parameters, dimensions, or installation forms between the first functional module 210A and the second functional module 210B can be the same or different.

[0096] See Figure 11, in the installation method of the second functional module 210, the functional module 210 may include a third functional module 210C. The second guide shell 120 is provided with a fourth installation structure 127 extending into the guide channel 300 at one end close to the first opening 112. The fourth installation structure 127 is adapted to install the third functional module 210C. It can be understood that the above is another type of setting relative to the embodiment of the first aspect of the present invention.
