[0049] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0050] As shown in Figures 1 to 5, the air guide plate assembly of this embodiment is an upward-discharge air guide plate assembly. The air guide plate assembly includes a mounting frame 1, a driving device 2, and an air guide plate 3. The driving device 2 is connected to the mounting frame 1. The driving device 2 is drively connected to the air guide plate 3 to drive the air guide plate 3 to move. As shown in Figures 8 and 9, the air guide plate 3 includes a first air guide surface 311, a transition air guide surface 313, and a second air guide surface 312 arranged sequentially along the Y direction in its width direction diagram. At least a portion of the first air guide surface 311 is inclined relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313, and at least a portion of the second air guide surface 312 is inclined relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313.

[0051] At least a portion of the first air guide surface 311 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313. This can be understood as: only a portion of the first air guide surface 311 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313; or, the entire first air guide surface 311 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313. At least a portion of the second air guide surface 312 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313. This can be understood as: only a portion of the second air guide surface 312 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313; or, the entire second air guide surface 312 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313.

[0052] For example, the transition air guide surface 313 is disposed on the side facing the thickness direction (Z direction in the figure) of the air guide plate body 31, at least a portion of the first air guide surface 311 is inclined relative to the transition air guide surface 313 along the other side facing the thickness direction of the air guide plate body 31, and at least a portion of the second air guide surface 312 is inclined relative to the transition air guide surface 313 along the other side facing the thickness direction of the air guide plate body 31. The length direction of the air guide plate body 31 is consistent with the X direction in the figure.

[0053] As shown in Figure 6, the air guide plate assembly is located at the air outlet 401 of the indoor unit 100 of the air conditioner. In cooling mode, the air at the air outlet 401 flows towards the first air guide surface 311 under the guidance of the transition air guide surface 313, and the airflow is mainly guided by the first air guide surface 311. As shown in Figure 7, in heating mode, the air at the air outlet 401 flows towards the second air guide surface 312 under the guidance of the transition air guide surface 313, and the airflow is mainly guided by the second air guide surface 312. By arranging at least a portion of the first air guide surface 311 at an angle relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313, the vortex formed by the airflow at the air guide plate 3 can be reduced, thereby reducing the risk of condensation problems in the indoor unit 100 of the air conditioner. By arranging at least a portion of the second air guide surface 312 at an angle relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313, the landing speed of the airflow passing through the air guide plate 3 can be increased, thereby improving the heating effect of the indoor unit 100 of the air conditioner.

[0054] In practical use, as shown in Figure 2, in heating mode, the air guide plate 3 is in the first position. The air guide plate 3 rotates until the second air guide surface 312 is located in front of the first air guide surface 311, and the front end of the air guide plate 3 is lower than its rear end. At this time, the airflow at the air outlet 401 is mainly guided by the second air guide surface 312. As shown in Figure 3, in cooling mode, the air guide plate 3 is in the second position. The air guide plate 3 rotates until the first air guide surface 311 is located in front of the second air guide surface 312, and the front and rear ends of the air guide plate 3 are roughly at the same height. At this time, the airflow at the air outlet 401 is mainly guided by the first air guide surface 311. During the operation of the indoor unit 100, the air guide plate 3 can also be in other positions, such as the third position shown in Figure 4.

[0055] In some embodiments, as shown in FIG9, the transition air guide surface 313 is an arc surface.

[0056] By setting the transition air guide surface 313 as an arc surface, the flow resistance of the transition air guide surface 313 to the airflow can be reduced, thereby increasing the air volume of the indoor unit 100 of the air conditioner.

[0057] In some embodiments, as shown in Figures 9 and 10, the first air guide surface 311 includes a first portion 3111 and a second portion 3112. The first portion 3111 is disposed between the second portion 3112 and the transition air guide surface 313 in the width direction of the air guide plate body 31. The first portion 3111 is smoothly connected to the transition air guide surface 313, and the second portion 3112 is arranged obliquely relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313.

[0058] Understandably, the second part 3112 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313, in order to reduce the vortex formed by the airflow at the air guide plate 3 and reduce the risk of condensation problems in the indoor unit 100 of the air conditioner.

[0059] When the airflow flows from the transition guide surface 313 to the first guide surface 311, it will first flow to the first part 3111 of the first guide surface 311. By smoothly connecting the first part 3111 to the transition guide surface 313, the flow resistance of the airflow from the transition guide surface 313 to the first guide surface 311 can be reduced, thereby increasing the air volume of the indoor unit 100 of the air conditioner.

[0060] In other embodiments, the first air guide surface 311 may be arranged at an angle relative to the transition air guide surface 313 along the direction opposite to the transition air guide surface 313.

[0061] In some embodiments, the included angle between the first portion 3111 and the second portion 3112 is 106° to 158°.

[0062] For example, as shown in Figure 10, the included angle between the first part 3111 and the second part 3112 is α, and α is 132°.

[0063] By setting the included angle between the first part 3111 and the second part 3112 to 106° to 158°, the eddy currents at the air guide plate 3 in the cooling mode can be effectively reduced, thereby reducing the risk of condensation problems in the indoor unit 100 of the air conditioner.

[0064] Of course, in other embodiments, the included angle between the first part 3111 and the second part 3112 can also be set to other angles outside the range of 106° to 158°.

[0065] In some embodiments, both the first portion 3111 and the second portion 3112 are planar.

[0066] By making both the first part 3111 and the second part 3112 flat, it is not only convenient to process and manufacture the air guide plate 3 and reduce the manufacturing cost of the air guide plate 3, but also to further reduce the eddy currents at the air guide plate 3 in the cooling mode, thereby reducing the risk of condensation problems in the indoor unit 100 of the air conditioner.

[0067] Of course, in some other embodiments, the first part 3111 and the second part 3112 may both be arc surfaces; or, one of the first part 3111 and the second part 3112 may be an arc surface and the other may be a plane.

[0068] In some embodiments, as shown in FIG10, a rounded corner is provided between the first portion 3111 and the second portion 3112.

[0069] By setting a rounded corner between the first part 3111 and the second part 3112, the flow resistance of airflow from the first part 3111 to the second part 3112 can be reduced, thereby increasing the air volume of the air conditioner indoor unit 100.

[0070] In some embodiments, as shown in Figures 9 and 11, the second air guide surface 312 includes a third portion 3121 and a fourth portion 3122. The third portion 3121 is disposed between the fourth portion 3122 and the transition air guide surface 313 in the width direction of the air guide plate body 31. The third portion 3121 is smoothly connected to the transition air guide surface 313, and the fourth portion 3122 is arranged obliquely relative to the transition air guide surface 313 in a direction away from the transition air guide surface 313.

[0071] Understandably, the fourth part 3122 is arranged at an angle relative to the transition air guide surface 313 along the direction away from the transition air guide surface 313, in order to increase the landing speed of the airflow passing through the air guide plate 3 and improve the heating effect of the air conditioner indoor unit 100.

[0072] When the airflow flows from the transition guide surface 313 to the second guide surface 312, it will first flow to the third part 3121 of the second guide surface 312. By smoothly connecting the third part 3121 to the transition guide surface 313, the flow resistance of the airflow from the transition guide surface 313 to the second guide surface 312 can be reduced, thereby increasing the air volume of the indoor unit 100 of the air conditioner.

[0073] In some embodiments, the third part 3121 is an arc surface and the fourth part 3122 is a plane.

[0074] As described above, when the airflow flows from the transition guide surface 313 to the second guide surface 312, it first flows to the third part 3121 of the second guide surface 312. By making the third part 3121 an arc surface, the flow resistance of the airflow from the transition guide surface 313 to the second guide surface 312 can be further reduced, thereby increasing the air volume of the air conditioner indoor unit 100. By making the fourth part 3122 a plane, the landing speed of the airflow passing through the guide plate 3 in heating mode can be further increased, thereby improving the heating effect of the air conditioner indoor unit 100.

[0075] In some embodiments, the third part 3121 is a concave arc surface.

[0076] Of course, in other embodiments, the third part 3121 and the fourth part 3122 may both be arc surfaces; or, the third part 3121 and the fourth part 3122 may both be planes; or, the third part 3121 may be a plane and the fourth part 3122 may be an arc surface.

[0077] In some embodiments, the radius of the third portion 3121 is 30 mm to 45 mm.

[0078] For example, as shown in Figure 11, the radius of the third part 3121 is R, and R is 37 mm.

[0079] By setting the radius of the third part 3121 to 30mm to 45mm, the landing speed of the airflow passing through the air guide plate 3 in the heating mode can be further improved, thereby improving the heating effect of the air conditioner indoor unit 100.

[0080] In some embodiments, the radius of the third portion 3121 is 18° to 28°.

[0081] For example, as shown in Figure 11, the radian of the third part 3121 is β, and β is 23°.

[0082] By setting the arc of the third part 3121 to 18° to 28°, the landing speed of the airflow passing through the air guide plate 3 in the heating mode can be further improved, thereby improving the heating effect of the air conditioner indoor unit 100.

[0083] In some embodiments, as shown in FIG11, a rounded corner is provided between the third portion 3121 and the fourth portion 3122.

[0084] By setting a rounded corner between the third part 3121 and the fourth part 3122, the flow resistance of the airflow from the third part 3121 to the fourth part 3122 can be reduced, thereby increasing the air volume of the indoor unit 100 of the air conditioner.

[0085] In some embodiments, the included angle between the first portion 3111 and the fourth portion 3122 is 42° to 62°.

[0086] For example, as shown in Figure 11, the angle between the first part 3111 and the fourth part 3122 is γ, and γ is 52°.

[0087] By setting the angle between the first part 3111 and the fourth part 3122 to 42° to 62°, the landing speed of the airflow passing through the air guide plate 3 in the heating mode can be further improved, thereby improving the heating effect of the air conditioner indoor unit 100.

[0088] As shown in Figures 8 and 9, the air guide plate 3 also includes a partition 32 and an outer plate 33, and the air guide plate body 31 is connected to the outer plate 33 through the partition 32.

[0089] For example, the partition 32 is connected to the air guide plate body 31 by a snap fastener, and the outer plate 33 of the air guide plate is bonded to the partition 32.

[0090] As shown in Figures 6 and 7, by optimizing the design of the air guide plate 3, the vortex formed at the front end of the air guide plate 3 can be reduced in the air conditioning indoor unit 100 during the cooling mode, thereby reducing the risk of condensation problems in the air conditioning indoor unit 100. In the heating mode, the hot airflow can quickly reach the ground, and the hot airflow is as close to the vertical angle with the ground as possible, ensuring that the hot airflow can reach the ground within one meter, thus improving the heating effect of the air conditioning indoor unit 100.

[0091] In some embodiments, as shown in Figures 5, 12, and 13, the driving device includes a mounting frame 1, a driving member 21, a rocker arm 22, and a limiting member 23. The driving member 21 is connected to the mounting frame 1 and is throttle-connected to the rocker arm 22 to drive the rocker arm 22 to rotate relative to the mounting frame 1. The rocker arm 22 has a protrusion 2222 on one axial side of its rotation axis. The limiting member 23 is disposed on the side of the rocker arm 22 facing the protrusion 2222 and connected to the mounting frame 1. The protrusion 2222 is rotatably connected to the limiting member 23.

[0092] In actual use, the swing arm 22 is connected to the air guide plate 3 via a transmission.

[0093] When the air guide plate assembly of this embodiment is in operation, the drive member 21 drives the swing arm 22 to rotate, and the swing arm 22 drives the air guide plate 3 to rotate to different air delivery angles. By providing a protrusion 2222 on one side of the axial direction of the swing arm 22's rotation axis, and providing a limiting member 23 on the side of the swing arm 22 facing the protrusion 2222, the protrusion 2222 and the limiting member 23 are rotatably connected, so that when the swing arm 22 rotates, the limiting member 23 can restrict the position of the swing arm 22 in the axial direction of the rotation axis, reducing the risk of the swing arm 22 wobbling, thereby improving the rotation accuracy of the air guide plate 3 and reducing the risk of abnormal noise from the swing arm 22.

[0094] In some embodiments, as shown in Figures 13 and 14, the protrusion 2222 is a shaft, the limiting member 23 is provided with a hole 2311, and the shaft is rotatably connected to the hole 2311.

[0095] By setting the protrusion 2222 as a shaft and the limiting member 23 as a hole 2311, the shaft and the hole 2311 are rotatably connected, which facilitates the rotatable connection between the protrusion 2222 and the limiting member 23, thereby facilitating the assembly of the drive device.

[0096] In some embodiments, the insertion shaft and the insertion hole 2311 are clearance-fitted.

[0097] The clearance fit between the insert shaft and the insert hole 2311 can improve the connection accuracy between the swing arm 22 and the limiting member 23, further reduce the risk of the swing arm 22 wobbling, further improve the rotation accuracy of the air guide plate 3, and reduce the risk of the swing arm 22 producing abnormal noise.

[0098] To make the technical solution of this disclosure easier to understand, the following describes the technical solution of this disclosure further by taking the example that the axis of the rotating shaft is consistent with the left and right directions. In this example, during the movement of the air guide plate 3, the X direction is consistent with the left and right directions.

[0099] For example, as shown in Figures 12 and 13, the right side of the swing arm 22 is provided with a protrusion 2222, the limiting member 23 is provided on the right side of the swing arm 22, the insertion hole 2311 extends in the left and right direction, and the protrusion 2222 is inserted into the insertion hole 2311 from left to right.

[0100] In some embodiments, as shown in FIG13, the limiting member 23 includes a guide hole 2312, which is disposed on the side of the insertion hole 2311 facing the rocker arm 22 and communicates with the insertion hole 2311. The diameter of the guide hole 2312 gradually increases in the direction away from the insertion hole 2311.

[0101] For example, as shown in Figure 13, the rocker arm 22 is located on the left side of the limiting member 23, the guide hole 2312 is located on the left side of the insertion hole 2311, and the diameter of the guide hole 2312 gradually increases from right to left.

[0102] By setting a guide hole 2312, the guide hole 2312 can guide the protrusion 2222 during the process of inserting the protrusion 2222 into the guide hole 2312, thereby facilitating the assembly of the drive device.

[0103] In some embodiments, as shown in FIG13, the rocker arm 22 includes an extension 2211 disposed on the side of the protrusion 2222 away from the limiting member 23. At least a portion of the extension 2211 is disposed within the guide hole 2312, and the diameter of the extension 2211 gradually increases in the direction away from the insertion hole 2311.

[0104] For example, the extension 2211 is provided on the left side of the protrusion 2222, and the diameter of the extension 2211 gradually increases from right to left. A portion of the extension 2211 is provided inside the guide hole 2312, and another portion of the extension 2211 is provided outside the guide hole 2312.

[0105] By providing an extension section 2211 to the swing arm 22, and the diameter of the extension section 2211 gradually increases in the direction away from the insertion hole 2311, the rigidity of the swing arm 22 can be improved, further reducing the risk of the swing arm 22 swaying, improving the rotation accuracy of the air guide plate 3, and reducing the risk of abnormal noise from the swing arm 22.

[0106] In some embodiments, as shown in Figures 13 and 16, the rocker arm 22 includes a rod body 221 and a limiting rod 222. The rod body 221 is connected to the drive member 21. The limiting rod 222 includes a first segment 2221 and a second segment, which are arranged axially along the axis of rotation. The first segment 2221 is fixedly connected to the rod body 221, and the second segment forms a protrusion 2222.

[0107] For example, the rod body 221 is located on the left side of the limiting rod 222, the first segment 2221 is located on the left side of the second segment, the first segment 2221 is embedded in the rod body 221, the second segment is located on the outside of the rod body 221, and the second segment forms a protrusion 2222.

[0108] By setting the pendulum 22 to the above structure, it is convenient to design and manufacture different parts of the pendulum 22 according to the requirements of different parts of the pendulum 22, so that the rigidity of the pendulum 22 meets the requirements while keeping the cost of the pendulum 22 low.

[0109] In some embodiments, as shown in Figures 13 and 16, the diameter of the first segment 2221 is larger than the diameter of the second segment.

[0110] By setting the diameter of the first segment 2221 to be larger than that of the second segment, not only can the connection area between the limiting rod 222 and the rod body 221 be increased, thereby improving the connection reliability between the limiting rod 222 and the rod body 221, but the limiting rod 222 can also be prevented from falling off the limiting member 23 in a direction away from the rod body 221, thus improving the reliability of the driving device.

[0111] In some embodiments, the limiting rod 222 is a metal rod.

[0112] By making the limiting rod 222 a metal rod, the coefficient of friction between the limiting rod 222 and the limiting member 23 can be reduced, avoiding abnormal noise caused by friction between the swing rod 22 and the limiting member 23 during rotation, and further reducing the risk of abnormal noise during the rotation of the swing rod 22.

[0113] In some embodiments, the rod body 221 is made of plastic, and the rod body 221 and the limiting rod 222 are integrally injection molded.

[0114] In some embodiments, the limiting member 23 is detachably connected to the mounting bracket 1.

[0115] For example, as shown in Figure 17, the limiting member 23 has a fixing hole 2321, and the fastener passes through the fixing hole 2321 and is connected to the mounting bracket 1. The fastener can be a bolt, screw, etc.

[0116] By detachably connecting the limiting member 23 to the mounting bracket 1, it is convenient to replace and repair the limiting member 23.

[0117] In some embodiments, as shown in FIG17, the limiting member 23 includes a limiting body 231 and a fixing ear 232. The fixing ear 232 is disposed on opposite sides of the limiting body 231 in the radial direction of the rotating shaft and is connected to the limiting body 231. The protrusion 2222 is rotatably connected to the limiting body 231, and the fixing ear 232 is connected to the mounting bracket 1.

[0118] For example, as shown in Figure 17, the insertion hole 2311 is provided on the limiting body 231, and the fixing ear 232 is provided on the upper and lower sides of the limiting body 231. During the movement of the air guide plate 3, the angles between the Y and Z directions and the up and down directions will change.

[0119] By setting the limiting member 23 to include the limiting body 231 and the fixing ear 232, different parts of the limiting member 23 are connected to the protrusion 2222 and the mounting bracket 1 respectively, which further facilitates the installation and fixing of the limiting member 23 and further facilitates the assembly of the drive device.

[0120] In some embodiments, the limiting body 231 and the fixing ear 232 are integrally formed.

[0121] For example, the limiting body 231 and the fixing ear 232 are integrally injection molded.

[0122] In some embodiments, as shown in Figures 5, 12, and 13, the drive device further includes a reduction gearbox 24. The reduction gearbox 24 includes a housing 241 and an output shaft 242. The housing 241 is connected to the mounting bracket 1, and the drive component 21 is connected to the rocker arm 22 via the output shaft 242. The drive component 21 can be a motor, and multiple gears are disposed within the housing 241.

[0123] By setting up a reduction gearbox 24, the output torque of the drive component 21 can be increased, the output torque of the swing arm 22 can be increased, and the rotational stability of the air guide plate 3 can be improved.

[0124] In some embodiments, as shown in Figures 5, 12 and 13, the gearbox 24 and the limiting member 23 are arranged on opposite sides of the rocker arm 22 in the axial direction of the rotating shaft.

[0125] For example, the gearbox 24 is located on the left side of the swing arm 22, and the limiting member 23 is located on the right side of the swing arm 22. The gearbox 24 and the limiting member 23 can be used to stably limit the swing arm 22 in the left and right directions, further reducing the risk of the swing arm 22 swaying, further improving the rotation accuracy of the air guide plate 3, and reducing the risk of abnormal noise from the swing arm 22.

[0126] In some embodiments, the rigidity of the swing arm 22 can be increased by increasing the dimension of the swing arm 22 in the axial direction of the rotating shaft, thereby reducing the risk of the swing arm 22 wobbling, further improving the rotation accuracy of the air guide plate 3, and reducing the risk of abnormal noise from the swing arm 22.

[0127] As shown in Figures 3 and 4, the air guide plate assembly also includes a rotating rod 34, one end of which is connected to the air guide plate 3, and the other end of which is rotatably connected to the swing rod 22.

[0128] For example, one end of the rotating rod 34 is integrally formed with the air guide plate body 31. As shown in Figures 12 and 14, the swing rod 22 is provided with a connecting part 223, which is rotatably connected to the rotating rod 34.

[0129] By rotating the rod 34 and swinging the rod 22, the air guide plate 3 can rotate relative to the swinging rod 22, thereby making the opening angle of the air outlet 401 larger during the movement of the air guide plate 3, and making it easier to achieve large-angle air delivery.

[0130] In some embodiments, as shown in FIG18, the air guide plate assembly further includes an air guide frame 5, with a gap between the air guide frame 5 and the mounting frame 1, and a portion of the drive device 2 is disposed between the air guide frame 5 and the mounting frame 1.

[0131] For example, a portion of the swing arm 22 is positioned between the air guide frame 5 and the mounting frame 1.

[0132] This allows the space between the air guide frame 5 and the mounting frame 1 to allow the swing arm 22 to swing, thereby increasing the rotation angle of the swing arm 22. This results in a larger opening angle of the air outlet 401 during the movement of the air guide plate 3, making it easier to achieve large-angle air delivery.

[0133] As shown in Figure 5, the indoor unit 100 of the air conditioner in this embodiment includes a housing 4 and an air guide plate assembly. The housing 4 is provided with an air outlet 401, and the air guide plate 3 is provided corresponding to the air outlet 401 to close and open the air outlet 401.

[0134] The air outlet 401 is located on the front and near the top of the outer casing 4, so that the indoor unit 100 of the air conditioner has an upward air outlet. During the movement of the air guide plate 3, the angles between the Y and Z directions and the front-back direction will change.

[0135] As shown in Figures 2 to 4, the outer casing 4 is also provided with an air inlet 402, which is located at the lower part of the outer casing 4. The indoor unit 100 of the air conditioner also includes an evaporator 6, which is located inside the outer casing 4.

[0136] In actual use, indoor air enters the interior of the outer casing 4 through the air inlet 402 on the lower side of the indoor unit 100 of the air conditioner, passes through the evaporator 6 and exchanges heat with the evaporator 6, and then flows out from the air outlet 401 on the upper side of the indoor unit 100 of the air conditioner and blows into the room.

[0137] In some embodiments, as shown in FIG1, the housing 4 includes a front side panel 403, an air outlet 401 is disposed on the front side panel 403, and the front side panel 403 is arranged to gradually tilt backward in a top-to-bottom direction.

[0138] By arranging the front panel 403 to gradually tilt backward from top to bottom, airflow can also pass through the lower side of the air outlet 401 in heating mode, thereby making the airflow entering through the air inlet 402 at a higher temperature, realizing the internal circulation of hot airflow, which can sterilize the evaporator 6 at high temperature and prevent odors from appearing in the indoor unit 100 of the air conditioner.

[0139] In some embodiments, as shown in FIG1, the tilt angle of the front side panel 403 is 6° to 14°.

[0140] For example, the tilt angle of the front side panel 403 is θ, where θ is 10°.

[0141] Understandably, the larger the tilt angle of the front panel 403, the more hot air enters through the air inlet 402, and the better the high-temperature sterilization effect of the evaporator 6. However, there is less hot air in the room, which is not conducive to improving the heating effect of the air conditioner indoor unit 100. On the other hand, the smaller the tilt angle of the front panel 403, the less hot air enters through the air inlet 402, and the more hot air in the room. This is conducive to improving the heating effect of the air conditioner indoor unit 100, but the high-temperature sterilization effect of the evaporator 6 is worse.

[0142] By setting the tilt angle of the front panel 403 to 6° to 14°, the high-temperature sterilization effect of the evaporator 6 can be guaranteed without affecting the indoor heating effect.

[0143] In some embodiments, as shown in FIG5, the indoor unit of the air conditioner includes a middle frame, which forms a mounting bracket 1.

[0144] By using the middle frame as mounting bracket 1, the drive unit can be integrated and mounted on the middle frame, thereby improving the integration of the indoor air conditioning unit.

[0145] The air conditioner indoor unit 100 of this embodiment can reduce the eddies formed by airflow at the air guide plate 3, thereby reducing the risk of condensation problems in the air conditioner indoor unit 100; it can also increase the landing speed of the airflow passing through the air guide plate 3, thereby improving the heating effect of the air conditioner indoor unit 100. The air conditioner indoor unit 100 of this embodiment can reduce the risk of swaying of the swing arm 22, improve the rotation accuracy of the air guide plate 3, and reduce the risk of abnormal noise from the swing arm 22. In addition, the rigidity of the swing arm 22 is improved, avoiding the problem of closed gaps or inconsistencies between the actual rotation angle and the ideal rotation angle in the air guide plate 3 due to deformation of the swing arm 22.
