[0032] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0033] As Figures 1 to 5 shown, the air conditioner indoor unit 100 of the embodiments of the present disclosure includes a middle frame 10, an air deflector 20 and a driving device 30. The middle frame 10 is provided with an air outlet 101. The air deflector 20 is movably arranged at the air outlet 101 to open or close the air outlet 101. The driving device 30 is arranged on one side of the middle frame 10 close to the air outlet 101 and is installed on the middle frame 10. The driving device 30 is connected to the air deflector 20 to drive the air deflector 20 to move. Among them, the air conditioner indoor unit 100 can be of a wall-mounted structure.

[0034] When the air conditioner indoor unit 100 of the embodiments of the present disclosure works, the driving device 30 drives the air deflector 20 to move, so that the air deflector 20 can open or close the air outlet 101 of the middle frame 10. By arranging the driving device 30 on one side of the middle frame 10 close to the air outlet 101 and installing the driving device 30 on the middle frame 10, the layout compactness between the air deflector 20 and the driving device 30 can be improved, the occupied space of the air deflector 20 and the driving device 30 can be reduced, and the size of the air conditioner indoor unit 100 can be reduced.

[0035] As Figure 2 shown, the middle frame 10 is further provided with an air inlet 102. Among them, the air inlet 102 is arranged below the air outlet 101, and the air outlet 101 faces forward. The air conditioner indoor unit 100 further includes an evaporator 40. Among them, the up-down direction is as Figures 1 to 5 shown, and the front-back direction is as Figure 1 、 Figure 2 and Figure 5 shown.

[0036] When the air conditioner indoor unit 100 is working, indoor air can enter through the air inlet 102 , pass through the evaporator 40 and exchange heat with the evaporator 40 , and then flow back into the room through the air outlet 101 .

[0037] In some embodiments, as Figures 2 to 8 As shown, the drive device 30 includes a drive member 2, a reduction gearbox 5, and a rocker arm 3. The reduction gearbox 5 is mounted on the middle frame 10. One end of the rocker arm 3 is connected to the drive member 2 through the reduction gearbox 5, and the other end of the rocker arm 3 is connected to the air deflector 20. The drive member 2 can be a motor.

[0038] For example, the reduction gearbox 5 includes a housing 51 and an output shaft 52 . The housing 51 is connected to the middle frame 10 . A plurality of gears are provided in the housing 51 . The driving member 2 is connected to the rocker arm 3 through the output shaft 52 .

[0039] By providing the reduction box 5 , the output torque of the driving member 2 can be increased, the output torque of the rocker arm 3 can be increased, and thus the movement stability of the air guide plate 20 can be improved.

[0040] like Figure 4 、 Figure 5 and Figure 8 As shown, the swing arm 3 is provided with a connecting portion 33, and the connecting portion 33 is connected to the wind deflector 20. The connecting portion 33 and the wind deflector 20 can be clamped.

[0041] like Figures 4 to 7 As shown, the reduction box 5 is arranged on one side of the rocker arm 3 in the axial direction of the rotating shaft of the rocker arm 3 , and a gear protrusion 53 is provided on the side of the reduction box 5 away from the rocker arm 3 , and the gear protrusion 53 is rotatably connected to the middle frame 10 .

[0042] In order to make the embodiments of the present disclosure easier to understand, the following takes the case where the axial direction of the rotating shaft of the swing rod 3 is consistent with the left and right directions as an example to further describe the technical solution of the present disclosure. Figure 1 、 Figures 3 to 9 、 Figure 11 shown.

[0043] For example, Figures 4 to 8 As shown, the reduction box 5 is arranged on the left side of the rocker arm 3 , and a gear protrusion 53 is provided on the left side of the reduction box 5 , and the gear protrusion 53 is rotatably connected to the middle frame 10 .

[0044] By providing a gear protrusion 53 on the side of the reduction box 5 away from the rocker arm 3, and the gear protrusion 53 is rotatably connected to the middle frame 10, when the gear in the reduction box 5 rotates, the middle frame 10 can be used to limit the axial position of the driving device 30 on the rotating shaft, thereby reducing the risk of shaking of the driving device 30, thereby improving the rotation accuracy of the air guide plate 20 and reducing the risk of abnormal noise generated by the rocker arm 3.

[0045] Optionally, the gear protrusion 53 is a limiting post, and the middle frame 10 is provided with a limiting hole, and the limiting post is rotatably connected to the limiting hole.

[0046] By setting the gear protrusion 53 as a limiting post and the middle frame 10 with a limiting hole, and using the limiting post to be rotatably connected to the limiting hole, it is convenient for the gear protrusion 53 to be rotatably connected to the middle frame 10, thereby facilitating the installation and fixation of the driving device 30.

[0047] Optionally, the gear protrusion 53 is coaxially arranged with the output shaft 52.

[0048] Optionally, the reduction gearbox 5 is detachably connected to the middle frame 10.

[0049] For example, as Figure 8 shown, the housing 51 is provided with a connecting ear 511, the connecting ear 511 is provided with a connecting hole 5111, and the fastener passes through the connecting hole 5111 and is connected to the middle frame 10 to realize the connection and fixation of the housing 51 and the middle frame 10. Among them, the fastener can be a bolt, a screw, etc.

[0050] By detachably connecting the reduction gearbox 5 to the middle frame 10, it is convenient to replace and repair the reduction gearbox 5.

[0051] In some embodiments, as Figures 4 to 8 shown, a limiting member 4 is provided on the side of the swing rod 3 away from the reduction gearbox 5, the limiting member 4 is connected to the middle frame 10, and the swing rod 3 is connected to the limiting member 4.

[0052] For example, a limiting member 4 is provided on the right side of the swing rod 3, and the swing rod 3 is connected to the limiting member 4.

[0053] By connecting the swing rod 3 to the limiting member 4, when the swing rod 3 rotates, the position of the swing rod 3 can be restricted by the limiting member 4, reducing the risk of the swing rod 3 shaking, thereby improving the rotation accuracy of the air deflector 20 and reducing the risk of abnormal noise generated by the swing rod 3.

[0054] In addition, the reduction gearbox 5 and the limiting member 4 are arranged on opposite sides of the swing rod 3, which can achieve stable limiting of the driving device 30 in the axial direction of the rotating shaft of the swing rod 3, reducing the risk of the driving device 30 shaking, further improving the rotation accuracy of the air deflector 20 and reducing the risk of abnormal noise generated by the swing rod 3.

[0055] Optionally, as Figures 4 to 8 shown, a swing rod protrusion 322 is provided on the side of the swing rod 3 away from the reduction gearbox 5, and the swing rod protrusion 322 is rotatably connected to the limiting member 4.

[0056] For example, as Figures 7 to 9 shown, a swing rod protrusion 322 is provided on the right side of the swing rod 3, the limiting member 4 is arranged on the right side of the swing rod 3, and the swing rod protrusion 322 is inserted into the limiting member 4 from left to right.

[0057] By rotatably connecting the protruding part 322 of the swing rod with the limiting member 4, when the swing rod 3 rotates, the limiting member 4 can be used to limit the position of the swing rod 3 in the axial direction of the rotating shaft, reducing the risk of the swing rod 3 shaking, thereby improving the rotation accuracy of the air deflector 20 and reducing the risk of abnormal noise generated by the swing rod 3.

[0058] Optionally, as Figure 7 shown, the protruding part 322 of the swing rod is an insertion shaft, and the limiting member 4 is provided with an insertion hole 411, and the insertion shaft is rotatably connected with the insertion hole 411.

[0059] By setting the protruding part 322 of the swing rod as an insertion shaft and arranging the insertion hole 411 in the limiting member 4, and using the rotational connection between the insertion shaft and the insertion hole 411, it is convenient for the rotational connection between the protruding part 322 of the swing rod and the limiting member 4, thereby facilitating the assembly of the driving device 30.

[0060] Optionally, the insertion shaft and the insertion hole 411 are in clearance fit.

[0061] The clearance fit between the insertion shaft and the insertion hole 411 can improve the connection accuracy between the swing rod 3 and the limiting member 4, further reduce the risk of the swing rod 3 shaking, further improve the rotation accuracy of the air deflector 20 and reduce the risk of abnormal noise generated by the swing rod 3.

[0062] Optionally, as Figure 7 shown, the limiting member 4 includes a guiding hole 412, and the guiding hole 412 is arranged on the side of the insertion hole 411 facing the swing rod 3 and communicates with the insertion hole 411. The diameter of the guiding hole 412 gradually increases in the direction away from the insertion hole 411.

[0063] For example, as Figure 7 shown, the swing rod 3 is arranged on the left side of the limiting member 4, the guiding hole 412 is arranged on the left side of the insertion hole 411, and the diameter of the guiding hole 412 gradually increases in the direction from right to left.

[0064] By arranging the guiding hole 412, during the process of inserting the protruding part 322 of the swing rod into the guiding hole 412, the guiding hole 412 can play a guiding role for the protruding part 322 of the swing rod, facilitating the insertion of the protruding part 322 of the swing rod into the guiding hole 412, thereby facilitating the assembly of the driving device 30.

[0065] Optionally, as Figure 7 shown, the swing rod 3 includes an extension section 311, and the extension section 311 is arranged on the side of the protruding part 322 of the swing rod away from the limiting member 4. At least a part of the extension section 311 is arranged in the guiding hole 412, and the diameter of the extension section 311 gradually increases in the direction away from the insertion hole 411.

[0066] For example, the extension section 311 is arranged on the left side of the swing rod protruding part 322, and the diameter of the extension section 311 gradually increases in the direction from right to left. A part of the extension section 311 is arranged inside the guide hole 412, and another part of the extension section 311 is arranged outside the guide hole 412.

[0067] By arranging the extension section 311 on the swing rod 3 and making the diameter of the extension section 311 gradually increase in the direction away from the jack 411, the stiffness of the swing rod 3 can be improved, the risk of the swing rod 3 shaking can be further reduced, the rotation accuracy of the air deflector 20 can be improved, and the risk of abnormal noise generated by the swing rod 3 can be reduced.

[0068] In some embodiments, as Figure 7 and Figure 10 shown, the swing rod 3 includes a rod body 31 and a limiting rod 32. The rod body 31 is in transmission connection with the driving member 2. The limiting rod 32 includes a first section 321 and a second section. The second section and the first section 321 are arranged along the axial direction of the rotating shaft. The first section 321 is fixedly connected to the rod body 31, and the second section forms the swing rod protruding part 322.

[0069] For example, the rod body 31 is arranged on the left side of the limiting rod 32, the first section 321 is arranged on the left side of the second section, the first section 321 is embedded in the rod body 31, the second section is located outside the rod body 31, and the second section forms the swing rod protruding part 322.

[0070] By setting the swing rod 3 as the above structure, it is convenient to design and manufacture different parts of the swing rod 3 according to the requirements of different parts of the swing rod 3, so that the stiffness of the swing rod 3 meets the requirements under the condition of relatively low cost of the swing rod 3.

[0071] Optionally, as Figure 10 shown, the diameter of the first section 321 is larger than that of the second section.

[0072] By setting the diameter of the first section 321 to be larger than that of the second section, not only can the connection area between the limiting rod 32 and the rod body 31 be increased, thereby improving the connection reliability between the limiting rod 32 and the rod body 31; but also the limiting rod 32 can be prevented from falling off the limiting member 4 in the direction away from the rod body 31, improving the reliability of the driving device 30.

[0073] Optionally, the swing rod protruding part 322 is a metal part.

[0074] For example, the limiting rod 32 is a metal rod.

[0075] By setting the swing rod protruding part 322 as a metal part, the friction coefficient between the limiting rod 32 and the limiting member 4 can be reduced, and abnormal noise generated by friction between the swing rod 3 and the limiting member 4 during the rotation of the swing rod 3 can be avoided, further reducing the risk of abnormal noise generated during the rotation of the swing rod 3.

[0076] Optionally, the rod body 31 is made of plastic, and the rod body 31 and the limiting rod 32 are integrally injection-molded.

[0077] In some embodiments, the limiting member 4 is detachably connected to the middle frame 10.

[0078] For example, as Figure 11 shown, the limiting member 4 is provided with a fixing hole 421, and a fastening member passes through the fixing hole 421 and is connected to the middle frame 10. Among them, the fastening member can be a bolt, a screw, etc.

[0079] By detachably connecting the limiting member 4 to the middle frame 10, it is convenient to replace and repair the limiting member 4.

[0080] Optionally, as Figure 11 shown, the limiting member 4 includes a limiting main body 41 and fixing ears 42. The fixing ears 42 are arranged on opposite sides of the limiting main body 41 in the radial direction of the rotating shaft and are connected to the limiting main body 41. The protruding part 322 of the swing rod is rotatably connected to the limiting main body 41, and the fixing ears 42 are connected to the middle frame 10.

[0081] For example, as Figure 11 shown, the jack 411 is arranged on the limiting main body 41, and the fixing ears 42 are arranged on the upper and lower sides of the limiting main body 41.

[0082] By setting the limiting member 4 to include the limiting main body 41 and the fixing ears 42, different parts of the limiting member 4 are respectively connected to the protruding part 322 of the swing rod and the middle frame 10, which further facilitates the installation and fixation of the limiting member 4 and further facilitates the assembly of the driving device 30.

[0083] Optionally, the limiting main body 41 and the fixing ears 42 are integrally formed.

[0084] For example, the limiting main body 41 and the fixing ears 42 are integrally injection-molded.

[0085] Optionally, the minimum dimension of the swing rod 3 in the axial direction of its rotating shaft is 12 mm to 24 mm.

[0086] For example, as Figure 9 shown, the minimum dimension of the swing rod 3 in the left-right direction is L, and L is 12.5 mm.

[0087] By increasing the dimension of the swing rod 3 in the axial direction of the rotating shaft, the stiffness of the swing rod 3 is improved, the risk of the swing rod 3 shaking is reduced, the rotation accuracy of the air deflector 20 is further improved, and the risk of abnormal noise generated by the swing rod 3 is reduced.

[0088] The air conditioner indoor unit 100 according to the embodiments of the present disclosure reduces the occupied space of the air deflector 20 and the driving device 30, and reduces the size of the air conditioner indoor unit 100. It can also reduce the risk of the swing rod 3 shaking, improve the rotation accuracy of the air deflector 20, and reduce the risk of abnormal noise generated by the swing rod 3. In addition, the stiffness of the swing rod 3 is improved, avoiding problems such as the existence of a closing gap of the air deflector 20 or the inconsistency between the actual rotation angle and the ideal rotation angle due to the deformation of the swing rod 3.
