[0002] In the related art, the air duct device of an air conditioner includes a first air duct component and a second air duct component.

[0050] The following will describe the air duct device 2 according to the present invention with reference to the accompanying drawings. Figure 1-10 Describe the air duct device 2 according to the present invention.

[0051] As Figure 1 and Figure 2 shown, the air duct device 2 according to the present invention can be applied to an air conditioner indoor unit. The air duct device 2 can be located between the air inlet 13 and the air outlet 14 of the air conditioner 1. Airflow enters the interior of the air conditioner 1 through the air inlet 13. A left air duct 201 and a right air duct 202 are provided inside the air duct device 2. The airflow is respectively led out through different air outlets 14 through the left air duct 201 and the right air duct 202.

[0052] The air duct device 2 includes a first air duct component 21 and a second air duct component 22. A part of the above-mentioned left air duct 201 and right air duct 202 is provided in the first air duct component 21, and another part of the left air duct 201 and right air duct 202 is provided in the second air duct component 22. After the first air duct component 21 and the second air duct component 22 are combined, a complete left air duct 201 and right air duct 202 are formed. Corresponding air wheel assemblies 3 can be provided in the left air duct 201 and the right air duct 202. The air wheel assemblies 3 rotate in the corresponding air ducts, and the air wheel assemblies 3 can drive the airflow in the corresponding left air duct 201 and right air duct 202 to flow.

[0053] One end of the first engaging portion 23 is provided on the first air duct component 21, and the second air duct component 22 is formed with a mating groove 220 adapted to cooperate with the other end of the first engaging portion 23. The first air duct component 21 is connected to the second air duct component 22 through the first engaging portion 23 and defines the left air duct 201 and the right air duct 202 located on the left and right sides of the first engaging portion.

[0054] A first engaging portion 23 is provided on the first air duct member 21, and the first air duct member 21 and the second air duct member 22 are connected by means of plug-in fit, which improves the structural stability of the air duct device 2. The connection strength between the first air duct member 21 and the second air duct member 22 is higher, and the connecting member between the left air duct 201 and the right air duct 202 will not deflect, and the stability of the air duct system is better.

[0055] In an embodiment of the present invention, the first engaging portion 23 included in the air duct device 2 is provided on the first air duct member 21, and one end of the first engaging portion 23 connected to the first air duct member 21 is smaller than the width of the other end of the first engaging portion 23 away from the first air duct member 21.

[0056] The first engaging portion 23 is a connection structure for connecting the first air duct member 21 and the second air duct member 22. In the related art, the connection surface of the first engaging portion 23 is too narrow, resulting in the second air duct member 22 being prone to lateral deflection. The lateral deflection of the second air duct member 22 affects the performance of the air duct system, resulting in noise and abnormal sounds in the air conditioner 1.

[0057] According to the air duct device 2 of the present invention, the first engaging portion 23 is provided on the first air duct member 21, and the first air duct member 21 and the second air duct member 22 are connected by means of the first engaging portion 23. To ensure the connection strength between the first air duct member 21 and the second air duct member 22 and reduce the deflection of the second air duct member 22, the first engaging portion 23 is configured such that the width of the end connected to the first air duct member 21 is smaller than the end of the first engaging portion 23 engaged with the second air duct member 22, thereby increasing the structural strength of the side of the first engaging portion 23 away from the first air duct member 21 and improving the structural strength at the connection position between the first engaging portion 23 and the second air duct member 22.

[0058] The first engaging portion 23 is configured such that the width at the position connected to the second air duct member 22 is greater than the width of the first engaging portion 23 connected to the first air duct member 21, strengthening the strength at the connection position between the second air duct member 22 and the first engaging portion 23. An installation plane with a larger installation area and better strength is formed on the first engaging portion 23, so that the second air duct member 22 remains stable after installation with the first air duct member 21. The lateral deflection effect of the second air duct member 22 relative to the first air duct member 21 is weakened, improving the structural stability and reliability of the air duct device 2.

[0059] According to the air duct member of the present invention, by setting the width of the end of the first engaging portion 23 cooperating with the second air duct member 22 to be greater than the end of the first engaging portion 23 cooperating with the first air duct member 21, the connection strength between the first engaging portion 23 and the second air duct member 22 is improved, so that the first air duct member 21 and the second air duct member 22 will not deflect in the left-right direction, and the stability of the internal air duct system of the air duct device 2 is improved.

[0060] According to one embodiment of the present invention, the wider other end of the first combining portion 23 has a first fixing portion 231, and the second air duct component 22 is provided with a second fixing portion 221 corresponding to the first fixing portion 231. The second air duct component 22 is connected to the first combining portion 23 by the cooperation between the first fixing portion 231 and the second fixing portion 221.

[0061] The first fixing portion 231 and the second fixing portion 221 may be connected by a fastener, or the first fixing portion 231 and the second fixing portion 221 may be fixedly connected by snap-fitting.

[0062] According to one embodiment of the present invention, the air duct device 2 also includes a fastener, which is used to connect the first fixing portion 231 and the second fixing portion 221. The fastener is inserted into the second air duct component 22 from the side of the second air duct component 22 away from the first air duct component 21. Since most of the structures in the air duct device 2 are assembled in front of the air duct device 2 facing the air outlet 14, and the side of the second air duct component 22 away from the first air duct component 21 is the front of the air duct device 2, in the related art, the installation between the first air duct component 21 and the second air duct component 22 needs to be performed from the back of the air duct device 2, and the air duct device 2 needs to be turned over as a whole before the fastener is installed. This installation method is cumbersome and difficult for workers to operate.

[0063] The fastener is arranged to be installed from the side of the second air duct component 22 away from the first air duct component 21, so that the installation process between the first air duct component 21 and the second air duct component 22 can be carried out in front of the air duct device 2. During the installation of the first air duct component 21 and the second air duct component 22, there is no need to flip the air duct device 2, thereby improving the installation efficiency between the first air duct component 21 and the second air duct component 22.

[0064] The fastener is connected to the first fixing part 231 after passing through the second fixing part 221. The fastener can be constructed as a bolt. The screw portion of the bolt passes through the second fixing part 221. When the rod portion of the bolt cooperates with the first air duct component 21, the head of the bolt is continuously pressed against the side of the second fixing part 221 facing the front of the air duct device 2 to fix the second air duct component 22 on the first air duct component 21.

[0065] like Figure 3 and Figure 4As shown, according to an embodiment of the present invention, the air duct device 2 further includes a deflector 24. The deflector 24 is disposed on a side of the second air duct component 22 facing the front of the air duct device 2. The deflector 24 can be used to further guide and separate the airflows in the left air duct 201 and the right air duct 202, isolate the airflows in the left air duct 201 and the right air duct 202, and further guide the airflows in the left air duct 201 and the right air duct 202.

[0066] According to an embodiment of the present invention, the deflector 24 is fixed to a side of the second air duct component 22 facing away from the first air duct component 21. The deflector 24 and the second air duct component 22 form a second air duct assembly, and the second air duct assembly is fixed to the first air duct component 21.

[0067] In the air duct device 2, the left air duct 201 and the right air duct 202 need to be separated by the first air duct component 21 and the second air duct component 22. The deflector 24 is disposed on the second air duct component 22 to extend the left air duct 201 and the right air duct 202, and further guide the airflow, ensuring that the airflows in the left air duct 201 and the right air duct 202 do not affect each other, and improving the stability of the airflow in the left air duct 201 and the airflow in the right air duct 202.

[0068] According to an embodiment of the present invention, during the installation of the air duct device 2, the deflector 24 and the second air duct component 22 can be first combined into a second air duct assembly, and then the second air duct assembly can be installed on the first air duct component 21. Since the size of the deflector 24 is small, the process of installing the deflector 24 alone is cumbersome. By first forming the deflector 24 and the second air duct component 22 into a second air duct assembly and then installing it on the first air duct component 21, the deflector 24 and the second air duct component 22 can be installed simultaneously, so as to reduce the installation process and improve the assembly efficiency of the air duct device 2.

[0069] According to an embodiment of the present invention, the deflector 24 is fixed to a side of the second air duct component 22 facing away from the first air duct component 21. During the installation and fixation of the deflector 24 and the second air duct component 22 to the first air duct component 21, the same set of fasteners can be used. One of the fasteners in the set can sequentially pass through the deflector 24 and the second fixing part 221 and then be fixed to the first fixing part 231. The fasteners connect three components, namely the deflector 24, the second air duct component 22, and the first air duct component 21, thereby reducing the number of components and omitting the step of separately installing the deflector 24 on the second air duct component 22.

[0070] According to an embodiment of the present invention, there are a plurality of first fixing portions 231, which are arranged at intervals in the width direction of the wider other end of the first engaging portion 23. Correspondingly, the second fixing portions 221 are also configured to be plural. The plurality of first fixing portions 231 and the plurality of second fixing portions 221 can improve the connection reliability between the flow guide plate 24, the second air duct member 22 and the first air duct member 21.

[0071] In an embodiment of the present invention, the first fixing portion 231 can be configured as a stud provided at the other end of the first engaging portion 23, and a threaded hole adapted to cooperate with a fastener can be provided inside the stud.

[0072] According to an embodiment of the present invention, there are a plurality of second fixing portions 221. The plurality of second fixing portions 221 correspond to the plurality of first fixing portions 231 one by one, so that each second fixing portion 221 is provided with a connection structure corresponding to the first fixing portion 231, ensuring the firm and reliable connection between the second air duct member 22 and the first air duct member 21.

[0073] The second air duct member 22 includes a second air duct member body 222 and a partition rib 223 provided on the second air duct member body 222. The partition rib 223 is configured to protrude toward the first air duct member 21, and a part of the second fixing portions 221 is located on one side of the partition rib 223, and another part of the second fixing portions 221 is located on the other side of the partition rib 223.

[0074] As Figure 6 and Figure 9 shown, the second fixing portion 221 can be configured as a through hole. The second fixing portion 221 can be an even number such as two or four. The second fixing portions 221 are symmetrically distributed on both sides of the partition rib 223. The partition rib 223 can improve the structural strength of the second air duct member 22, especially the strength at the connection position between the second air duct member 22 and the first engaging portion 23, thereby reducing the yaw of the second air duct member 22 relative to the first air duct member 21.

[0075] As Figure 4 and Figure 6As shown, according to an embodiment of the present invention, the first fixing portion 231 includes a first fixing post 2311. There is a first fixing hole 2312 inside the first fixing portion 231. The first fixing post 2311 is configured as a columnar structure protruding from the other end of the first joint portion 23, and the upper end of the first fixing post 2311 protrudes from the upper surface of the other end of the first joint portion 23. A second fixing portion 221 is provided on the second air duct member 22, and the second fixing portion 221 is configured as a multi-segment hole. The multi-segment hole includes at least two segments connected in sequence. The hole segment facing the first air duct member 21 is a large hole segment 224 with a larger diameter, and the hole segment located on the side of the large hole segment 224 away from the first air duct member 21 is a small hole segment 225. The radial dimension of the large hole segment 224 is larger than the radial dimension of the small hole segment 225. Since the first fixing post 2311 protrudes from the other end of the first joint portion 23, a part of the first fixing post 2311 can be accommodated in the large hole segment 224, so as to perform pre-positioning between the first fixing portion 231 and the second fixing portion 221. After the pre-positioning is completed, the first fixing portion 231 and the second fixing portion 221 are respectively connected by fasteners. The fasteners can sequentially pass through the small hole segment 225 and the large hole segment 224 and then cooperate with the threaded hole in the first fixing post 2311 to press the second air duct member 22 onto the first air duct member 21.

[0076] The first joint portion 23 according to the present invention includes a first joint portion body 232. The first joint portion body 232 has a pair of first joint portion side walls 233 arranged oppositely. The first joint portion side walls 233 can be arranged in the width direction of the first joint portion body 232. The first fixing portion 231 is provided on the first joint portion side walls 233. The first fixing portion 231 can be configured as two, and the two first fixing portions 231 can be provided on each first joint portion side wall 233.

[0077] The two first joint portion side walls 233 can extend towards the second air duct member 22. At the same time, the two first joint portion side walls 233 gradually move away from each other in the extending direction. The two first fixing portions 231 are provided on the surfaces of the corresponding first joint portion side walls 233 facing each other. When the first joint portion 23 cooperates with the second air duct member 22, the connection between the first fixing portion 231 and the second fixing portion 221 can be hidden inside the two first joint portion side walls 233, so that after the air duct device 2 is assembled, the combination of the first fixing portion 231 and the second fixing portion 221 is hidden, improving the aesthetics of the air duct device 2. At the same time, the first joint portion side walls 233 and the second joint portion side walls can be used to reduce the air leakage problem between the left air duct 201 and the right air duct 202.

[0078] According to an embodiment of the present invention, the first fixing post 2311 protrudes from the side wall 233 of the first joint portion towards the second air duct component 22, and the protruding portion extends into the large hole section 224 of the positioning post. The upper end of the first fixing post 2311 is higher than the height of the side wall 233 of the first joint portion, so that at least a part of the first fixing post 2311 is exposed outside the side wall 233 of the first joint portion, so that a part of the first fixing post 2311 can cooperate with the large hole section 224 to perform pre-positioning between the first fixing post 2311 and the large hole section 224. When the fastener does not connect the first air duct component 21 and the second air duct component 22, the positions of the first air duct component 21 and the second air duct component 22 can be kept relatively stable through the cooperation between the first fixing post 2311 and the large hole section 224, so as to facilitate the subsequent connection of the first fixing portion 231 and the second fixing portion 221 by screws, thereby improving the connection efficiency between the first air duct component 21 and the second air duct component 22.

[0079] According to an embodiment of the present invention, a first step surface 234 is provided at the other end of the side wall 233 of the first joint portion, and a second step surface 226 is provided on the second air duct component 22. When the first joint portion 23 is matched with the second air duct component 22, the first step surface 234 and the second step surface 226 abut against each other to support the second air duct component 22 by the first joint portion 23, so that the first joint portion 23 remains stable when being matched with the second air duct component 22, and is stable and reliable during the pre-positioning process of the first joint portion 23 and the second air duct component 22.

[0080] In an embodiment of the present invention, a first step surface 234 is provided at the side edge of the side wall 233 of the first joint portion away from the first air duct component 21, and a second step surface 226 is provided at the outer edge of the second air duct component 22 facing the first joint portion 23.

[0081] In an embodiment of the present invention, the first step surface 234 and the second adjustment surface can be configured as non-horizontal surfaces. The first step surface 234 can be formed with an inclined wall surface at the free end in the extending direction of the side wall 233 of the first joint portion, and the second step surface 226 is configured as a surface facing the first step surface 234. After the first joint portion 23 is matched with the second air duct component 22, the first step surface 234 and the second step surface 226 abut against each other to ensure the reliable and stable cooperation between the first joint portion 23 and the second air duct component 22, and seal the left air duct 201 and the right air duct 202, reducing the air leakage between the left air duct 201 and the right air duct 202.

[0082] According to an embodiment of the present invention, the first air duct component 21 includes a first air duct component body 211 and a first partition portion 212. A partial left air duct 201 and a partial right air duct 202 may be provided within the first air duct component body 211. The first partition portion 212 separates the left air duct 201 and the right air duct 202. A first engaging portion 23 is provided on the first partition portion 212, and the first engaging portion 23 is located on the first partition portion 212 and protrudes toward the second air duct component 22.

[0083] In the second air duct component 22, a second air duct component body 222 and a second partition portion 227 provided on the second air duct component body 222 are provided. Another partial left air duct 201 and another partial right air duct 202 may be provided within the second air duct component body 222. The second partition portion 227 separates the another partial left air duct 201 and the another partial right air duct 202. At the same time, the first partition portion 212 and the second partition portion 227 may be disposed opposite to each other and connected to separate the left air duct 201 and the right air duct 202, thereby ensuring the sealing ability between the left air duct 201 and the right air duct 202 and reducing the seal between the left air duct 201 and the right air duct 202.

[0084] According to an embodiment of the present invention, the second partition portion 227 includes two segments, and the two segments of the second partition portion 227 are disconnected from each other. The first engaging portion 23 may be inserted between the two segments of the second partition portion 227. The first engaging portion 23 is combined with the two segments of the second partition portion 227 in the extending direction to connect the two segments of the second partition portion 227, so as to form a complete separating structure in the second air duct component 22 for separating the left air duct 201 and the right air duct 202. A foregoing fitting groove 220 is formed between the two segments of the second partition portion 227.

[0085] Inserting the first engaging portion 23 between the two segments of the second partition portion 227 can combine the first engaging portion 23 with the structure on the second air duct component 22, so that the first engaging portion 23 can be hidden in the second air duct component 22 to reduce the overall volume of the air duct device 2, make the connection and cooperation between the first air duct component 21 and the second air duct component 22 more reliable, have a better sealing effect between the left air duct 201 and the right air duct 202, effectively prevent air leakage between the left air duct 201 and the right air duct 202, and improve the tightness between the left air duct 201 and the right air duct 202.

[0086] Such as Figure 8 and Figure 10As shown, according to an embodiment of the present invention, the first partition portion 212 and the second partition portion 227 have an embedded mating portion. To further improve the sealing effect between the left air duct 201 and the right air duct 202, an embedded portion is provided on the first partition portion 212 and the second partition portion 227 to extend the sealing gap in contact between the first partition portion 212 and the second partition portion 227, thereby further avoiding the mutual flow of air between the left air duct 201 and the right air duct 202, reducing the mutual influence of the air flow between the left air duct 201 and the right air duct 202, and improving the stability of the air flow in the air duct device 2.

[0087] According to an embodiment of the present invention, a first partition groove 2121 is provided on the first partition portion 212, and a first partition protrusion 2272 is provided on the second partition portion 227. The first partition protrusion 2272 is inserted into the first partition groove 2121. After the first partition protrusion 2272 and the first partition groove 2121 are matched, the contact area between the first partition portion 212 and the second partition portion 227 is larger, so that the extension distance of the sealing gap between the first partition portion 212 and the second partition portion 227 in the cross section is longer, and the distance of the gap that the air flow needs to pass through when flowing between the left and right air ducts is farther, further improving the sealing performance between the left air duct 201 and the right air duct 202, reducing the mutual influence between the left air duct 201 and the right air duct 202, improving the structural stability of the air duct device 2, and ensuring the stability and reliability of the air duct system performance of the air duct device 2.

[0088] According to an embodiment of the present invention, a positioning groove 2122 is further provided in the first partition groove 2121, and a positioning protrusion 2273 is further provided on the first partition protrusion 2272. The positioning protrusion 2273 is inserted and positioned in the positioning groove 2122. The positioning protrusion 2273 and the positioning groove 2122 can cooperate with each other to position the positions of the first partition portion 212 and the second partition portion 227, so that the first air duct component 21 and the second air duct component 22 will not move in the extending direction of the first partition portion 212 after being matched. The cooperation between the positioning protrusion 2273 and the positioning groove 2122 can also prevent the left and right yaw between the first air duct component 21 and the second air duct component 22. The positioning protrusion 2273 cooperates with the peripheral wall of the positioning groove 2122. When the second air duct component 22 yaws relative to the first air duct component 21, the positioning protrusion 2273 and the side wall of the positioning groove 2122 abut against each other, and opposite acting forces are generated between the positioning protrusion 2273 and the side wall of the positioning groove 2122, thereby supporting the second air duct component 22 and avoiding yaw between the second air duct component 22 and the first air duct component 21.

[0089] As Figure 9As shown, according to an embodiment of the present invention, the second air duct component 22 includes a partition rib 223 provided on the second air duct component body 222. The partition rib 223 protrudes towards the first air duct component 21. The partition rib 223 is connected between two sections of the second partition part 227. The partition rib 223 is respectively connected to the end parts of the two sections of the second partition part 227 that face each other, and can be used to strengthen the strength of the two second partition parts 227. The partition rib 223 and the two second partition parts 227 can be made into an integrally formed structure, so that the second air duct component 22, the second partition part 227, and the partition rib 223 are integrally formed, enabling the second air duct component 22 to have good structural strength after forming, and reducing the problem of weakened strength caused by disconnection in the formed part.

[0090] As Figure 9 shown, in an embodiment of the present invention, an intermediate bump 229 is provided between the partition rib 223 and the second partition part 227. Intermediate bumps 229 are provided at one end of each of the two sections of the second partition part 227 facing the partition rib 223. The intermediate bump 229 can be similar to the cross-section of the end face of each second partition part 227, and the area of the intermediate bump 229 is smaller than the area of the end face of the second partition part 227, so as to create a step difference between the intermediate bump 229 and the second partition part 227, enabling the outer peripheral part of the end faces of the two sections of the second partition part 227 that face each other to be exposed, and the above-mentioned partition rib 223 is provided between the two intermediate bumps 229.

[0091] As Figure 7 and Figure 9 shown, according to an embodiment of the present invention, the first engaging part 23 includes a first engaging part body 232. The first engaging part body 232 has a pair of first engaging part side walls 233 and a pair of first engaging part end walls 235 that are oppositely arranged. The longitudinal two ends of the first engaging part side walls 233 protrude from the first engaging part end walls 235 to form convex ribs 236. The two convex ribs 236 of the pair of first engaging part side walls 233 are respectively fitted on both sides of the intermediate bump 229.

[0092] As Figure 4 、 Figure 7 and Figure 9As shown, the convex rib 236 cooperates with the outer edge of the intermediate convex block 229, which can further improve the stability of the first joint portion 23 and the second air duct member 22. The first joint portion 23 is provided in the middle of the first air duct member 21. The first joint portion 23 also needs to prevent the air flow from surging between the left air duct 201 and the right air duct 202. After the first joint portion 23 is inserted between the two second partition portions 227, through the cooperation between the convex rib 236 and the outer edge of the intermediate convex block 229, the contact area between the first joint portion 23 and the two second partition portions 227 is larger, and at the same time, the two second partition portions 227 can be used to support the first joint portion 23, improving the sealing effect between the first joint portion 23 and the two second partition portions 227.

[0093] The convex rib 236 can overlap on the intermediate convex block 229, so that the contact area between the convex rib 236 and the intermediate convex block 229 is larger, preventing the air flow from passing through the gap between the two second partition portions 227 and preventing the air flow from passing through the gap at the position where the second partition portion 227 cooperates with the first joint portion 23, further weakening the mutual influence between the left air duct 201 and the right air duct 202 and improving the air duct performance of the air duct device 2.

[0094] As Figure 7 shown, according to an embodiment of the present invention, a pair of first joint portion end walls 235 have avoidance notches 237 for avoiding the partition rib 223. By providing the avoidance notches 237 for the partition rib 223 on the first joint portion end walls 235, the partition rib 223 can be embedded into the first joint portion end walls 235, so that the cooperation between the first joint portion 23 and the second air duct member 22 is tighter, reducing the volume after the cooperation between the first joint portion 23 and the second air duct member 22. Moreover, the partition rib 223 can be accommodated in the avoidance notch 237, and the side walls of the partition rib 223 and the side walls of the avoidance notch 237 abut against each other to support the partition rib 223. When there is a yaw between the second air duct member 22 and the first joint portion 23, a reaction force can be generated on the wall surface where the partition rib 223 abuts against the avoidance notch 237 to limit the yaw between the second air duct member 22 and the first joint portion 23, so that the cooperation between the second air duct member 22 and the first air duct member 21 is more reliable, weakening the yaw effect between the first air duct member 21 and the second air duct member 22 and improving the aerodynamic performance of the air duct device 2.

[0095] According to an embodiment of the present invention, the distance between a pair of side walls 233 of the first joint portion increases gradually from the end connected to the first joint portion 23 towards the other end. It can be understood that the width of the first joint portion 23 gradually increases in the direction from the end connected to the first air duct member 21 towards the other end protruding towards the second air duct member 22. By setting it like this, the size of the first joint portion 23 can be increased, further enhancing the structural strength of the first joint portion 23. Especially after the first joint portion 23 cooperates with the second air duct member 22, it can support the second air duct member 22, improving the connection strength between the first air duct member 21 and the second air duct member 22, and preventing the first air duct member 21 and the second air duct member 22 from deflecting.

[0096] According to an embodiment of the present invention, a pair of end walls 235 of the first joint portion are connected between a pair of side walls 233 of the first joint portion, so that the first joint portion 23 is constructed as a hollow structure, and the first joint portion 23 has a structure similar to a triangular prism with one side open. The two side walls 233 of the first joint portion are two sides of the triangular prism-like structure. The upper surfaces of the two side walls 233 of the first joint portion are open, and a plurality of first fixing portions 231 are provided on the two side walls 233 of the first joint portion. The two end walls 235 of the first joint portion are respectively located at both ends of a pair of side walls 233 of the first joint portion to ensure the structural strength stability of the first joint portion 23, so that the first joint portion 23 is constructed as a prism-like structure with a continuous wall surface, ensuring the structural stability of the first joint portion 23 itself, and enabling connections to be generated between the respective wall surfaces to ensure the performance of the first joint portion 23.

[0097] As Figure 4 and Figure 7 shown, according to an embodiment of the present invention, the outer wall surface of the side wall 233 of the first joint portion is constructed as a first guiding outer wall surface 238. The first guiding outer wall surface 238 is constructed as a smooth wall surface and an arc-shaped wall surface that is concave towards each other, so as to improve the air flow path inside the air duct device 2 and enhance the stability of air flow. The outer wall surfaces on both sides of the second partition portion 227 are constructed as second guiding outer wall surfaces 2271 for guiding the air flow. The second guiding outer wall surface 2271 is constructed as a smooth wall surface and an arc-shaped wall surface that is concave towards each other. The curvature of the first guiding outer wall surface 238 can be the same as the curvature of the second guiding outer wall surface 2271. The first guiding outer wall surface 238 and the second guiding outer wall surface 2271 are spliced with each other to form a complete guiding outer wall surface. After the first joint portion 23 is inserted into two sections of the second partition portion 227, the first guiding outer wall surface 238 of the first joint portion 23 and the second guiding outer wall surface 2271 of the second partition portion 227 are spliced with each other to form a complete guiding outer wall surface in the extending direction of the second partition portion 227. The guiding outer wall surface is arranged between the left air duct 201 and the right air duct 202, and guides the air flow in the left air duct 201 and the right air duct 202 respectively.

The first separation protrusion 2272 is inserted into the first separation groove 2121. After the first separation protrusion 2272 is engaged with the first separation groove, the contact area between the first separation part 212 and the second separation part 227 is larger, so that the distance of the sealing gap between the first separation part 212 and the second separation part 227 in the cross section is longer, further improving the sealing performance between the left air duct 201 and the right air duct 202, reducing the mutual influence between the left air duct 201 and the right air duct 202, improving the structural stability of the air duct device 2, and ensuring the stability and reliability of the air duct system performance of the air duct device 2.

The cooperation between the positioning protrusion 2273 and the positioning groove 2122 can also prevent the left and right yaw between the first air duct member 21 and the second air duct member 22. The positioning protrusion 2273 cooperates with the peripheral wall of the positioning groove 2122. When the second air duct member 22 yaws relative to the first air duct member 21, the positioning protrusion 2273 and the side wall of the positioning groove 2122 abut against each other, and opposite acting forces are generated between the positioning protrusion and the side wall of the positioning groove 2122, thereby supporting the second air duct member 22 and preventing yaw between the second air duct member 22 and the first air duct member 21.
