[0036] 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.

[0037] As Figures 1 to 5As shown in the figure, the air conditioner indoor unit 100 according to an embodiment of the present disclosure includes a middle frame 10, a wind guiding frame 40, a wind guiding plate 20 and a driving device 30. The middle frame 10 is provided with an air outlet 101. The wind guiding plate 20 is movably arranged at the air outlet 101 to open or close the air outlet 101. There is a gap between the wind guiding frame 40 and the middle frame 10. The driving device 30 is arranged between the wind guiding frame 40 and the middle frame 10, and the driving device 30 is installed on the middle frame 10. The driving device 30 is connected to the wind guiding plate 20 to drive the wind guiding plate 20 to move. Among them, the air conditioner indoor unit 100 can be of a wall-mounted structure.

[0038] When the air conditioner indoor unit 100 according to an embodiment of the present disclosure works, the driving device 30 drives the wind guiding plate 20 to move, so that the wind guiding plate 20 can open or close the air outlet 101 of the middle frame 10. By arranging the driving device 30 between the wind guiding frame 40 and the middle frame 10, the gap between the wind guiding frame 40 and the middle frame 10 can be used for the driving device 30 to move, so that the driving device 30 can drive the wind guiding plate 20 to move within a large range, increasing the adjustment range of the air outlet angle of the air conditioner indoor unit 100, better meeting the user's needs and improving the user experience.

[0039] In some embodiments, as Figure 2 and Figure 3 shown, the driving device 30 includes a driving mechanism and a swing rod 3. The driving mechanism is installed on the middle frame 10. The first end of the swing rod 3 is connected to the driving mechanism, and the second end of the swing rod 3 is connected to the wind guiding plate 20.

[0040] Thus, the gap between the wind guiding frame 40 and the mounting frame 1 can be used for the swing rod 3 to swing, so that the rotation angle of the swing rod 3 can be increased, the adjustment range of the air outlet angle of the air conditioner indoor unit 100 is larger, better meeting the user's needs and improving the user experience.

[0041] Optionally, as Figures 3 to 5 shown, the wind guiding frame 40 is provided with a receiving cavity 401 for receiving the swing rod 3.

[0042] By providing the receiving cavity 401 in the wind guiding frame 40, sufficient receiving space is reserved for the swing rod 3 inside the air conditioner indoor unit 100. While the structure of the air conditioner indoor unit 100 is compact, it is beneficial to increase the rotation angle of the swing rod 3, so that the adjustment range of the air outlet angle of the air conditioner indoor unit 100 is larger, better meeting the user's needs and improving the user experience.

[0043] 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 50. Among them, the up-down direction and the front-back direction are as Figures 1 to 5 shown.

[0044] When the air conditioner indoor unit 100 is operating, indoor air can enter through the air inlet 102, pass through the evaporator 50 and exchange heat with the evaporator 50, and then flow back into the room through the air outlet 101.

[0045] In some embodiments, as Figures 6 to 9 shown, the driving mechanism includes a driving member 2 and a reduction gearbox 5, and the reduction gearbox 5 is installed on the middle frame 10. One end of the swing rod 3 is connected to the driving member 2 through the reduction gearbox 5, and the other end of the swing rod 3 is connected to the air deflector 20. Among them, the driving member 2 can be a driving motor.

[0046] For example, the reduction gearbox 5 includes a box body 51 and an output shaft 52. The box body 51 is connected to the middle frame 10, and the driving member 2 is in transmission connection with the swing rod 3 through the output shaft 52.

[0047] By setting the reduction gearbox 5, the output torque of the driving member 2 can be increased, the output torque of the swing rod 3 can be increased, and the movement stability of the air deflector 20 can be improved.

[0048] As Figure 7 and Figure 10 shown, the swing rod 3 is provided with a connecting portion 33, and the connecting portion 33 is connected to the air deflector 20. Among them, the connecting portion 33 and the air deflector 20 can be snap-connected.

[0049] As Figures 7 to 9 shown, the reduction gearbox 5 is arranged on one side of the swing rod 3 in the axial direction of the rotating shaft of the swing rod 3. A gear protrusion 53 is provided on the side of the reduction gearbox 5 away from the swing rod 3, and the gear protrusion 53 is rotatably connected to the middle frame 10.

[0050] To make the embodiments of the present disclosure easier to understand, taking the axial direction of the rotating shaft of the swing rod 3 being consistent with the left-right direction as an example, the technical solution of the present disclosure will be further described. Among them, the left-right direction is as Figure 1 、 Figures 4 to 8 、 Figures 10 to 13 shown.

[0051] For example, as Figures 6 to 8 shown, the reduction gearbox 5 is arranged on the left side of the swing rod 3, and a gear protrusion 53 is provided on the left side of the reduction gearbox 5. The gear protrusion 53 is rotatably connected to the middle frame 10.

[0052] By providing a gear protrusion 53 on the side of the reduction gearbox 5 away from the swing rod 3, and the gear protrusion 53 is rotatably connected to the middle frame 10, when the gears in the reduction gearbox 5 rotate, the position of the driving device 30 in the axial direction of the rotating shaft can be restricted by the middle frame 10, the risk of the driving device 30 shaking can be reduced, thereby improving the rotation accuracy of the air deflector 20 and reducing the risk of abnormal noise generated by the swing rod 3.

[0053] Optionally, the gear protrusion 53 is a limit post, and the middle frame 10 is provided with a limit hole, and the limit post is rotatably connected to the limit hole.

[0054] By setting the gear protrusion 53 as a limit post and the middle frame 10 with a limit hole, and using the rotational connection between the limit post and the limit hole, it is convenient for the gear protrusion 53 to be rotatably connected to the middle frame 10, thus facilitating the installation and fixation of the driving device 30.

[0055] Optionally, the gear protrusion 53 is coaxially arranged with the output shaft 52.

[0056] Optionally, the reduction gearbox 5 is detachably connected to the middle frame 10.

[0057] For example, as Figure 9 shown, the housing 51 is provided with connecting lugs 511, the connecting lugs 511 are provided with connecting holes 5111, and the fasteners pass through the connecting holes 5111 and are connected to the middle frame 10 to realize the connection and fixation between the housing 51 and the middle frame 10. Among them, the fasteners can be bolts, screws, etc.

[0058] By detachably connecting the reduction gearbox 5 to the middle frame 10, it is convenient to replace and repair the reduction gearbox 5.

[0059] In some embodiments, as Figures 6 to 9 shown, the air conditioner indoor unit 100 further includes a limiting member 4, the limiting member 4 is connected to the middle frame 10, and the swing rod 3 is connected to the limiting member 4.

[0060] 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.

[0061] 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.

[0062] Optionally, the limiting member 4 and the reduction gearbox 5 are respectively arranged on opposite sides of the swing rod 3 in the axial direction of the rotation axis of the swing rod 3.

[0063] The reduction gearbox 5 and the limiting member 4 are arranged on opposite sides of the swing rod 3, which can realize stable limiting of the driving device 30 in the axial direction of the rotation axis 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.

[0064] Optionally, as Figures 8 to 10 shown, the swing rod 3 is provided with a swing rod protrusion 322 on one side in the axial direction of its rotation axis, the limiting member 4 is arranged on the side of the swing rod 3 facing the swing rod protrusion 322, and the swing rod protrusion 322 is rotatably connected to the limiting member 4.

[0065] For example, as Figures 8 to 10 shown, a protruding portion 322 of the swing rod 3 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 protruding portion 322 of the swing rod is inserted into the limiting member 4 from left to right.

[0066] By rotatably connecting the protruding portion 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.

[0067] Optionally, as Figure 8 shown, the protruding portion 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.

[0068] By setting the protruding portion 322 of the swing rod as an insertion shaft and arranging the insertion hole 411 on the limiting member 4, and using the rotation connection between the insertion shaft and the insertion hole 411, it is convenient for the protruding portion 322 of the swing rod to be rotatably connected with the limiting member 4, thereby facilitating the assembly of the driving device 30.

[0069] Optionally, the insertion shaft and the insertion hole 411 are in clearance fit.

[0070] 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.

[0071] Optionally, as Figure 8 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.

[0072] For example, as Figure 8 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.

[0073] By providing the guiding hole 412, during the process of inserting the protruding portion 322 of the swing rod into the guiding hole 412, the guiding hole 412 can play a guiding role for the protruding portion 322 of the swing rod, facilitating the insertion of the protruding portion 322 of the swing rod into the guiding hole 412, thereby facilitating the assembly of the driving device 30.

[0074] Optionally, as Figure 8 shown, the swing rod 3 includes an extension section 311, and the extension section 311 is arranged on the side of the protruding portion 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.

[0075] For example, the extension section 311 is disposed on the left side of the rocker protrusion 322, and the diameter of the extension section 311 gradually increases from right to left. A portion of the extension section 311 is disposed in the guide hole 412, and another portion of the extension section 311 is disposed outside the guide hole 412.

[0076] By providing an extension section 311 on the rocker arm 3, and gradually increasing the diameter of the extension section 311 in the direction away from the socket 411, the stiffness of the rocker arm 3 can be improved, further reducing the risk of the rocker arm 3 shaking, improving the rotation accuracy of the air guide plate 20, and reducing the risk of abnormal noise generated by the rocker arm 3.

[0077] In some embodiments, as Figure 8 and Figure 11 As shown, the rocker arm 3 includes a rod body 31 and a limiting rod 32. The rod body 31 is in driving 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 a rocker arm protrusion 322.

[0078] For example, the rod body 31 is set on the left side of the limiting rod 32, the first section 321 is set on the left side of the second section, the first section 321 is embedded in the rod body 31, and the second section is located outside the rod body 31, and the second section forms a rocker protrusion 322.

[0079] By setting the pendulum rod 3 to the above structure, it is convenient to design and manufacture different parts of the pendulum rod 3 according to the requirements of different parts of the pendulum rod 3, so that the stiffness of the pendulum rod 3 meets the requirements while the cost of the pendulum rod 3 is low.

[0080] Alternatively, as Figure 11 As shown, the diameter of the first section 321 is greater than the diameter of the second section.

[0081] By setting the diameter of the first section 321 to be larger than the diameter of the second section, not only can the connection area between the limit rod 32 and the rod body 31 be increased, thereby improving the connection reliability between the limit rod 32 and the rod body 31; but also the limit rod 32 can be prevented from falling off from the limit member 4 in a direction away from the rod body 31, thereby improving the reliability of the driving device 30.

[0082] Optionally, the rocker protrusion 322 is a metal part.

[0083] For example, the limiting rod 32 is a metal rod.

[0084] By making the protruding part 322 of the swing rod a metal part, the friction coefficient between the limiting rod 32 and the limiting part 4 can be reduced, avoiding abnormal noises generated by friction between the swing rod 3 and the limiting part 4 during the rotation of the swing rod 3, and further reducing the risk of abnormal noises generated during the rotation of the swing rod 3.

[0085] Optionally, the rod body 31 is made of plastic, and the rod body 31 and the limiting rod 32 are integrally injection-molded.

[0086] In some embodiments, the limiting part 4 is detachably connected to the middle frame 10.

[0087] For example, as Figure 12 shown, the limiting part 4 is provided with a fixing hole 421, and a fastener passes through the fixing hole 421 and is connected to the middle frame 10. Among them, the fastener can be a bolt, a screw, etc.

[0088] By detachably connecting the limiting part 4 to the middle frame 10, it is convenient to replace and repair the limiting part 4.

[0089] Optionally, as Figure 12 shown, the limiting part 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.

[0090] For example, as Figure 12 shown, a 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.

[0091] By making the limiting part 4 include the limiting main body 41 and the fixing ears 42, different parts of the limiting part 4 are respectively connected to the protruding part 322 of the swing rod and the middle frame 10, further facilitating the installation and fixation of the limiting part 4 and further facilitating the assembly of the driving device 30.

[0092] Optionally, the limiting main body 41 and the fixing ears 42 are integrally formed.

[0093] For example, the limiting main body 41 and the fixing ears 42 are integrally injection-molded.

[0094] Optionally, the minimum dimension of the swing rod 3 in the axial direction of its rotating shaft is 12 mm to 24 mm.

[0095] For example, as Figure 10 shown, the minimum dimension of the swing rod 3 in the left-right direction is L, and L is 12.5 mm.

[0096] 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 noises generated by the swing rod 3 is reduced.

[0097] Optionally, as Figure 13 shown, the swing rod 3 includes a first housing 301, a second housing 302 and a driving component 303. The first housing 301 is connected to the second housing 302 and encloses an installation cavity. The driving component 303 is arranged in the installation cavity. The driving component 303 is connected to the connecting portion 33 to drive the air deflector 20 to rotate relative to the swing rod 3.

[0098] Wherein, the first housing 301 and the second housing 302 can be snap-connected. The driving component 303 can include a motor and a plurality of gears, and one of the gears is coaxially and fixedly connected to the connecting portion 33.

[0099] The air conditioner indoor unit 100 of the embodiment of the present disclosure increases the adjustment range of the air outlet angle of the air conditioner indoor unit 100, better meets the user's needs, and improves the user experience. 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 the problem that the air deflector 20 has a closing gap or the actual rotation angle is inconsistent with the ideal rotation angle due to the deformation of the swing rod 3.
