The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 4According to an embodiment of the present invention, the exhaust assembly includes a duct frame 100, a louver assembly, and a linkage 300. The duct frame 100 includes a front panel 110 and a rear shell 120, which are detachably connected front to back. The front panel 110 has an air outlet 111 in the front-back direction, and the rear shell 120 is provided with an air guide channel 121. The air outlet 111 and the air guide channel 121 are connected to form an air outlet channel. The louver assembly includes a plurality of blades 200, all of which are located at the air outlet 111 and rotatably mounted on the front panel 110. The linkage 300 is located on the side of the blades 200 near the rear shell 120 and is rotatably connected to all the blades 200. The linkage 300 is movably mounted on the front panel 110.

[0034] The exhaust assembly provided by this invention allows the louver assembly blades 200 and linkage 300 to be assembled with the front panel 110 first, and then the rear shell 120 to be assembled last. Since the air duct frame 100 is divided into two independent parts, the front panel 110 and the rear shell 120, the length of the side wall of the air outlet 111 on the front panel 110 in the front-to-back direction can be designed to be shorter. This makes the side wall of the air outlet 111 less obstructive to the assembly process of the blades 200 and linkage 300, thereby reducing the assembly difficulty and making the assembly of the blades 200 and linkage 300 easier, which is beneficial to improving production efficiency.

[0035] In the specific implementation process, the rear shell 120 is fixedly installed on the outer shell of the air conditioner indoor unit, and the front panel 110 is directly fixed to the outer shell of the air conditioner indoor unit or fixedly connected to the rear shell 120, so that the air guide channel 121 on the rear shell 120 is connected to the air outlet 111 on the front panel 110.

[0036] In the specific implementation process, the front panel 110 and the rear shell 120 or the outer shell of the air conditioner indoor unit can be detachably connected by bolts, clips, etc. Therefore, when it is necessary to clean the louver assembly, the user can disassemble the entire front panel 110 and the louver assembly and other components on the front panel 110 together for easy cleaning, without having to disassemble and install the blades 200 one by one.

[0037] Reference Figure 1 According to some embodiments of the present invention, the length of the sidewall of the air outlet 111 in the front-to-back direction is less than 3 cm. As a result, the short sidewall length of the air outlet 111 causes less obstruction to the assembly of the louver assembly and the linkage 300, and the louver assembly and the linkage 300 can be assembled together from the front and rear sides of the front panel 110.

[0038] Reference Figure 3 , Figure 4According to some embodiments of the present invention, mounting members 113 are connected to the opposite side walls of the air outlet 111. The mounting members 113 are located on the side of the blade 200 near the rear housing 120, and the linkage 300 is movably mounted on the mounting members 113. Thus, the mounting members 113 can be used to complete the assembly of the linkage 300.

[0039] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present invention, all blades 200 are arranged in a vertical direction, and mounting members 113 are arranged in a vertical direction, with the mounting members 113 rotatably connected to all blades 200. Thus, both ends of each blade 200 can be rotatably mounted to the front panel 110, while the middle portion of the blade 200 is supported by mounting members 113 and linkage members 300, which can improve the installation strength of the blade 200. One or more mounting members 113 and linkage members 300 can be provided. In specific implementation, the number of mounting members 113 and linkage members 300 can be appropriately increased or decreased according to the length of the blade 200 in the left-right direction.

[0040] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the blade 200 is elastic, and a first connecting portion 210 is provided at both the left and right ends of the blade 200. A first shaft hole 211 is provided on one side wall of the first connecting portion 210 and the side wall of the air outlet 111, and a first rotating shaft 112 is provided on the other side wall. The first rotating shaft 112 is rotatably inserted into the first shaft hole 211. Therefore, during the assembly of the exhaust assembly, the elastic deformation of the blade 200 can be used to insert the first rotating shaft 112 into the first shaft hole 211, making assembly convenient and simple.

[0041] Reference Figure 3 , Figure 5 and Figure 6According to some embodiments of the present invention, the mounting component 113 is provided with a plurality of first connecting arms 1131, each first connecting arm 1131 being provided with a slot 1132, each blade 200 being provided with a second connecting portion 220, each second connecting portion 220 being provided with a second rotating shaft 221, the second rotating shaft 221 being coaxially arranged with the corresponding first rotating shaft 112, all the second rotating shafts 221 being arranged one-to-one with all the slots 1132, and the second rotating shaft 221 being rotatably engaged in the corresponding slot 1132, wherein the slot 1132 is connected to an inlet and outlet 1133 for the second rotating shaft 221 to enter and exit, and a first clearance groove 1134 is provided on one side of the first connecting arm 1131 for the blade 200 to move, so as to allow the blade 200 to rotate and limit the rotation range of the blade 200. With the above settings, during the assembly of the exhaust component, the second rotating shaft 221 can be inserted from the inlet / outlet 1133 of the slot 1132 into the corresponding slot 1132 to complete the rotational connection between the mounting part 113 and the blade 200, making assembly convenient and simple.

[0042] Reference Figure 3 , Figure 5 and Figure 7 According to some embodiments of the present invention, one end of the linkage 300 is provided with a guide groove 311, and the other end is provided with a plurality of second connecting arms 320. One side of each second connecting arm 320 is provided with a second clearance groove 322 for the movement of the blade 200. The second connecting arm 320 is provided with a second shaft hole 321. The mounting member 113 is provided with a guide post 1135, which is inserted into the guide groove 311. Therefore, the linkage 300 can utilize the fit between the guide post 1135 and the guide groove 311. The mounting component 113 is movable; all blades 200 are provided with a third connecting part 230, and each third connecting part 230 is provided with a third rotating shaft 231. All the third rotating shafts 231 are rotatably inserted into all the second shaft holes 321 in a corresponding manner. The second rotating shafts 221, the third rotating shafts 231, and the guide post 1135 on the blades 200 are arranged in a triangular pattern. Thus, a triangular support structure is formed between the mounting component 113, the linkage component 300, and the blades 200, improving the installation stability of the blades 200. With the above configuration, during the assembly of the exhaust assembly, it is only necessary to insert the guide post 1135 into the guide groove 311 to complete the movable installation of the linkage component 300 onto the mounting component 113. In addition, it is only necessary to insert the third rotating shaft 231 into the corresponding second shaft hole 321 to complete the rotational connection between the linkage component 300 and the blades 200. The above operations are not difficult to achieve, thus making the assembly of the exhaust assembly convenient and simple.

[0043] Reference Figure 1 , Figure 7 and Figure 8According to some embodiments of the present invention, both ends of the guide groove 311 are provided with locking positions 3111. When the guide post 1135 moves to the locking position 3111, the side wall of the guide groove 311 engages with the guide post 1135, generating a certain resistance, thereby positioning the rotation angle of the blade 200.

[0044] Reference Figure 3 and Figure 5 According to some embodiments of the present invention, the third rotating shaft 231 includes two spaced-apart elastic half-shafts 2311. Each elastic half-shaft 2311 has a limiting portion 2312 at its end. When the two elastic half-shafts 2311 approach each other, the limiting portions 2312 on the two elastic half-shafts 2311 can pass through the second shaft hole 321. After the two elastic half-shafts 2311 pass through the second shaft hole 321, the two limiting portions 2312 engage with the side wall of the second shaft hole 321 to prevent the third rotating shaft 231 from disengaging from the second shaft hole 321. Through the above arrangement, without adding other components that need to be assembled, the linkage 300 is prevented from disengaging from the third rotating shaft 231, preventing the linkage 300 from accidentally falling off, ensuring a simple structure and convenient assembly.

[0045] Reference Figure 3 In the specific implementation process, the third connecting part 230 and the mounting part 113 on the blade 200 are located on the same side of the linkage 300. Therefore, during the assembly of the exhaust assembly, while inserting the third rotating shaft 231 into the second shaft hole 321 on the linkage 300, the guide column 1135 can also be inserted into the guide groove 311, thus making the assembly more convenient and simple.

[0046] During the assembly of the exhaust assembly, the left and right ends of the blade 200 can be rotated and installed on the front panel 110, the second rotating shaft 221 on the blade 200 can be installed in the slot 1132 of the mounting part 113, and then the linkage 300 can be assembled.

[0047] Reference Figure 1 , Figure 7 According to some embodiments of the present invention, the linkage 300 is provided with a recess 310 protruding toward the mounting member 113, and the guide groove 311 is formed on the bottom wall of the recess 310. With the above arrangement, the strength of the linkage 300 can be improved without increasing the thickness of the linkage 300. At the same time, the mating positions between the third rotating shaft 231 and the linkage 300 and between the mounting member 113 and the linkage 300 are misaligned, thereby improving the installation stability of the blade 200.

[0048] Reference Figure 1 and Figure 8In some embodiments, the mounting member 113 protrudes outward from the air outlet 111 and abuts against the side wall of the air guide channel 121. A support plate 123 is provided inside the air guide channel 121, and the support plate 123 abuts against the mounting member 113. Through the above arrangement, the rear shell 120 can support the mounting member 113 and improve the structural strength.

[0049] According to some embodiments of the present invention, the mounting component 113 is integrally formed with the front panel 110 to reduce assembly steps and improve production efficiency.

[0050] Reference Figure 1 and Figure 4 According to some embodiments of the present invention, the air inlet 122 of the air guide duct 121 is disposed on one side of the rear shell 120, and a protective net 400 is detachably installed at the air inlet 122 to prevent large foreign objects from entering the interior of the air conditioning indoor unit from the air guide duct 121.

[0051] An indoor air conditioning unit according to a second aspect of the present invention includes the exhaust assembly described above. By employing the exhaust assembly described above, the difficulty of assembling the exhaust assembly of the air conditioning unit can be reduced, making the assembly of the blades 200 and the linkage 300 easier, which is beneficial to improving production efficiency.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
