[0042] The air duct assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 1-Figure 8 As shown, the air duct assembly 100 of the embodiment of the utility model includes a vortex tongue 1, a positioning member, and a bracket.

[0044] The vortex tongue 1 comprises a first end 11 and a second end 12 which are opposite to each other in a first direction. The second end 12 has a first mounting hole and a limiting surface 121 .

[0045] The bracket includes a first plate body 2 and a second plate body 3 . The first plate body 2 and the second plate body 3 are arranged opposite to each other in a first direction. The first plate body 2 is connected to the first end 11 , and the second plate body 3 is connected to the second end 12 .

[0046] The positioning member is arranged on the second plate body 3, and the positioning member has a first stop surface 411 and a second stop surface 51, and the first stop surface 411 and the second stop surface 51 form an angle. That is to say, the orientation of the first stop surface 411 is inconsistent with the orientation of the second stop surface 51. When the limiting surface 121 of the second end portion 12 is stopped on the first stop surface 411 and the second stop surface 51, the first stop surface 411 and the second stop surface 51 can limit the second end portion 12 in two different directions respectively, so as to achieve the purpose of positioning the second end portion 12 by the first stop surface 411 and the second stop surface 51. Among them, the angle formed by the first stop surface 411 and the second stop surface 51 ranges from greater than 0° to less than 180°. The angle formed by the first stop surface 411 and the second stop surface 51 needs to be determined according to the specific structure of the second end portion 12, and is not limited here.

[0047] The second plate body 3 has a second mounting hole 31, which is configured to correspond to the first mounting hole when the first stop surface 411 and the second stop surface 51 are both in contact with the limiting surface 121, and the second mounting hole 31 and the first mounting hole are suitable for matching with each other through screws.

[0048] When the limiting surface 121 of the second end portion 12 is in contact with the first stop surface 411 and the second stop surface 51, that is, after the first stop surface 411 and the second stop surface 51 position the second end portion 12, the second mounting hole 31 corresponds to the first mounting hole, so that the screw can be smoothly inserted into the second mounting hole 31 and the first mounting hole, thereby fixing the second end portion 12 of the vortex tongue 1 to the second plate body 3.

[0049] Compared with the related art, the air duct assembly 100 of the embodiment of the utility model can accurately position the second end 12 by stopping the limiting surface 121 of the second end 12 against the first stop surface 411 and the second stop surface 51 after the first end 11 is connected to the first plate body 2. Thus, the second mounting hole 31 corresponds to the first mounting hole, avoiding misalignment between the second mounting hole 31 and the first mounting hole, so that the screw can smoothly connect the first end 11 and the second plate body 3, thereby improving the assembly efficiency of the air duct assembly 100 of the embodiment of the utility model.

[0050] Therefore, the air duct assembly 100 of the embodiment of the utility model has the advantage of higher assembly efficiency.

[0051] In order to make the present application easier to understand, the air duct assembly 100 of the embodiment of the present invention is further described below by taking the first direction being consistent with the up and down direction as an example, taking the first limiting surface 121 facing left as an example, and taking the second limiting surface 121 facing forward as an example.

[0052] like Figure 1-Figure 8 As shown, the air duct assembly 100 of the embodiment of the utility model comprises a vortex tongue 1, a positioning member, a bracket, a side plate 5 and a connector 32.

[0053] The first plate body 2 and the second plate body 3 are arranged opposite to each other in the up-down direction, the first plate body 2 is connected to the first end 11 (i.e., the upper end of the vortex tongue 1), and the second plate body 3 is connected to the second end 12 (i.e., the lower end of the vortex tongue 1). The side plate 5 is connected to the first plate body 2 at the upper end, and the lower end of the side plate 5 is connected to the second plate body 3, and an air outlet channel is defined between the side plate 5, the first plate body 2, the second plate body 3 and the vortex tongue 1.

[0054] In some embodiments, the positioning member includes a first positioning portion and a second positioning portion, both of which are arranged on the second plate body 3, and the outer peripheral surface of part of the second end portion 12 forms a limiting surface 121. The limiting surface 121 of the second end portion 12 includes a left side portion corresponding to the first stop surface 411 and a rear portion corresponding to the second stop surface 51.

[0055] The first positioning portion is a first protrusion protruding toward the side close to the first plate body 2, and a portion of the outer surface of the first protrusion forms a first stop surface 411; and / or, the second positioning portion is a second protrusion protruding toward the side close to the first plate body 2, and a portion of the outer surface of the second protrusion forms a second stop surface 51.

[0056] In other words, the first positioning portion is a first protrusion protruding upward, and a portion of the outer surface of the first protrusion forms the first stop surface 411; or, the second positioning portion is a second protrusion protruding upward, and a portion of the outer surface of the second protrusion forms the second stop surface 51; or, the first positioning portion is a first protrusion protruding upward, and a portion of the outer surface of the first protrusion forms the first stop surface 411, and the second positioning portion is a second protrusion protruding upward, and a portion of the outer surface of the second protrusion forms the second stop surface 51.

[0057] At least one of the first positioning portion and the second positioning portion is an upward protrusion, which not only enables the at least one of the first positioning portion and the second positioning portion to achieve a positioning function for the second end portion 12, but also has a simple structure and is easy to manufacture.

[0058] Specifically, Figure 1-Figure 5 As shown, part of the wall surface of the side plate 5 forms the first stop surface 411 , that is, the wall surface of the side plate 5 , the second plate body 3 is provided with a protrusion 41 protruding upward, and the outer surface of part of the protrusion 41 forms the second stop surface 51 .

[0059] In other words, a portion of the wall surface of the side panel 5 forms a first limiting surface 121 facing the left side, and when the second end 12 abuts against the portion of the wall surface of the side panel 5, the portion of the wall surface of the side panel 5 can limit the second end 12 in the left-right direction. In addition, by using the wall surface of the side panel 5 to form the first limiting surface 121, the arrangement of other limiting parts is reduced, the structural redundancy of the air duct assembly 100 of the embodiment of the utility model is reduced, and the user experience is improved.

[0060] In some embodiments, the outer peripheral surface of part of the second end portion 12 forms a limiting surface 121, and a step portion (not shown in the figure) is provided on the second plate body 3, the step portion includes a tread and a bent kick surface, the kick surface is connected to the tread, at least part of the kick surface forms a first stop surface 411 and a second stop surface 51, and the first stop surface 411 and the second stop surface 51 are connected. The first stop surface 411 and the second stop surface 51 having an included angle are naturally formed by the bent kick surface, which can not only realize the positioning effect of the kick surface on the second end surface, but also improve the integrity of the first stop surface 411 and the second stop surface 51, thereby improving the user experience.

[0061] In some embodiments, Figure 1-Figure 5As shown, the positioning member further includes a third positioning portion 42, which is provided on one of the second plate body 3 and the side plate 5. The third positioning portion 42 has a third stop surface 421 for limiting the rotation of the vortex tongue 1, and the third stop surface 421 is flush with one of the first stop surface 411 and the second stop surface 51, and the third stop surface 421 is spaced from the one of the first stop surface 411 and the second stop surface 51. In other words, the third stop surface 421 is flush with the second stop surface 51; or, the third stop surface 421 is flush with the first stop surface 411.

[0062] For example Figure 2 As shown, the protrusion 41 is spaced apart from the third positioning portion 42 in the left-right direction, the third stop surface 421 is flush with the second stop surface 51 , and the direction of the third stop surface 421 is consistent with the direction of the second stop surface 51 .

[0063] The third stop surface 421 of the third positioning portion 42 cooperates with the first stop surface 411 and the second stop surface 51 to further limit the second end portion 12 to prevent the second end portion 12 from rotating relative to the first stop surface 411 and the second stop surface 51, thereby ensuring that when the first stop surface 411, the second stop surface 51 and the third stop surface 421 jointly limit the second end portion 12, the first mounting hole and the second mounting hole 31 have a higher matching accuracy.

[0064] In some embodiments, Figure 3 and Figure 5 As shown, the vortex tongue 1 has one of the clamping member 52 and the clamping hole 13, and the side plate 5 has the other of the clamping member 52 and the clamping hole 13, and the clamping member 52 and the clamping hole 13 match each other. In other words, the vortex tongue 1 has the clamping member 52, and the side plate 5 has the clamping hole 13 that matches with the clamping member 52; or, the vortex tongue 1 has the clamping hole 13, and the side plate 5 has the clamping member 52 that matches with the clamping hole 13. The vortex tongue 1 and the side plate 5 are connected by the clamping member 52 and the clamping hole 13, so that the side plate 5 can support the vortex tongue 1, ensure the straightness of the vortex tongue 1 in the up and down direction, and avoid the bending of the vortex tongue 1 during the installation process, which causes the misalignment of the first mounting hole and the second mounting hole 31.

[0065] Specifically, the side plate 5 has a clamping member 52, the clamping member 52 has a curved clamping hook portion, the vortex tongue 1 has a clamping hole 13 that matches the clamping member 52, and the first end portion 11 is rotatably connected to the first plate body 2. When the clamping member 52 matches the clamping hole 13, the clamping member 52 is first inserted into the clamping hole 13, and then the vortex tongue 1 is rotated to make the clamping hook portion rotate in the circumferential direction of the vortex tongue 1, so that the clamping hook portion is clamped on the side plate 5.

[0066] In some embodiments, there are multiple clamping members 52, the multiple clamping members 52 are spaced apart in the up-down direction, and there are multiple clamping holes 13. The multiple clamping holes 13 are spaced apart in the up-down direction, and the multiple clamping members 52 are matched with the multiple clamping holes 13 in a one-to-one correspondence. The vortex tongue 1 and the side plate 5 are connected through the multiple clamping holes 13 and the multiple clamping members 52, so that the side plate 5 provides more support to the vortex tongue 1, thereby further improving the structural strength of the vortex tongue 1 and preventing the vortex tongue 1 from bending and deforming during installation.

[0067] In some embodiments, Figure 6 As shown, the spacing distance between the clamping member 52 and the first plate 2 is consistent with the spacing distance between the clamping member 52 and the second plate 3. In other words, the connection structure between the vortex tongue 1 and the side plate 5 formed by the clamping hole 13 and the clamping member 52 is located in the middle of the vortex tongue 1.

[0068] It is understandable that, during installation, the vortex tongue 1 is prone to bend at its middle position. The middle position of the vortex tongue 1 is connected to the side plate 5, so that the middle position of the vortex tongue 1 can be supported by the side plate 5, thereby making it easy for the vortex tongue 1 to bend at its middle position, thereby avoiding the bending of the vortex tongue 1 during the installation process, resulting in misalignment of the first mounting hole and the second mounting hole 31.

[0069] In some embodiments, Figure 2 As shown, the plug-in component 32 is arranged on one of the second plate body 3 and the second end 12, and the other of the second plate body 3 and the second end 12 is provided with a socket (not shown in the figure) matched with the plug-in component 32. In other words, the plug-in component 32 is arranged on the second plate body 3, and the socket is arranged on the second end 12; or, the socket is arranged on the second plate body 3, and the plug-in component 32 is arranged on the second end 12. In other words, when assembling the connecting member into the first mounting hole and the second mounting hole 31, for example, assembling the screw, the plug-in component 32 is matched in the socket, and the plug-in component 32 can prevent the limiting surface 121 from being away from the first stop surface 411 and the second stop surface 51, so that the first stop surface 411 and the second stop surface 51 can limit the second end 12 without the need for manpower to press the vortex tongue 1 on the second end 12, thereby saving labor and improving practicality.

[0070] In some embodiments, Figure 2 As shown, the plug connector 32 is arranged on the second plate body 3, the plug hole is arranged on the end surface of the second end portion 12, and the end surface of the plug connector 32 is arranged obliquely relative to the second plate body 3. In other words, the end surface of the plug connector 32 is an inclined surface with one end located below the other end. The end surface of the plug connector 32 is arranged obliquely, so that the plug connector 32 is easier to insert into the plug hole, which reduces the difficulty of assembly and improves practicality.

[0071] In some embodiments, the plug connector 32 is rotatably connected to the second plate body 3. Specifically, a mounting groove is provided on the second plate body 3, and the plug connector 32 is rotatably disposed in the mounting groove. The plug connector 32 can rotate relative to the second plate body 3, so that the plug connector 32 can adjust the direction of its end face, so that the second end 12 can be installed from multiple angles, making it easier for the socket and the plug connector 32 to match, thereby further reducing the difficulty of assembly.

[0072] In some embodiments, the connector 32 and the second plate 3 are integrally formed, so that the connector 32 and the second plate 3 have better integrity, reducing the installation process of the connector 32 and the second plate 3, thereby further improving the installation efficiency.

[0073] In some embodiments, Figure 6 and Figure 7 As shown, the first plate body 2 is provided with one of the first positioning member and the first positioning hole 14, the first end portion 11 is provided with the other of the first positioning member and the first positioning hole 14, and the first positioning member cooperates with the first positioning groove. In other words, the first plate body 2 is provided with the first positioning member, and the first end portion 11 is provided with the first positioning hole 14; or, the first plate body 2 is provided with the first positioning hole 14, and the first end portion 11 is provided with the first positioning member. Thus, the first plate body 2 and the first end portion 11 are positioned and connected through the first positioning hole 14 and the first positioning member, which not only has a simple structure, but also facilitates the assembly of the first plate body 2 and the first end portion 11.

[0074] The indoor unit of the air conditioner of the embodiment of the utility model comprises a housing and an air duct assembly, wherein the air duct assembly is the air duct assembly 100 of any of the above embodiments. The indoor unit of the air conditioner of the embodiment of the utility model has the air duct assembly 100, after the first end 11 is connected to the first plate body 2, the limiting surface 121 of the second end 12 can be stopped against the first stop surface 411 and the second stop surface 51, so that the positioning member can accurately position the second end 12. Thus, the second mounting hole 31 corresponds to the first mounting hole, and the misalignment between the second mounting hole 31 and the first mounting hole is avoided, so that the screw can smoothly connect the first end 11 and the second plate body 3, thereby improving the assembly efficiency of the air duct assembly 100 of the embodiment of the utility model.

[0075] In some embodiments, there are multiple air duct assemblies 100, and the multiple air duct assemblies 100 are all arranged in the housing. The air conditioner indoor unit of the embodiment of the utility model realizes multiple air outlet channels to supply air to the room by setting multiple air duct assemblies 100, thereby improving the user experience.
