[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] The present invention proposes an air conditioner indoor unit, which can be a floor-standing air conditioner indoor unit or a vertically mounted air conditioner indoor unit, etc.; the present invention is described by taking a floor-standing air conditioner indoor unit as an example, but the present invention is not limited thereto. The air conditioner indoor unit is provided with an air inlet, an air outlet, and a heat exchange air duct connecting the air inlet and the air outlet, and the air outlet usually extends in the up and down direction. The air conditioner indoor unit usually also includes an indoor heat exchanger arranged in the heat exchange air duct, and the indoor heat exchanger is used to adjust the indoor air temperature, such as cooling or heating. The air conditioner indoor unit also includes a wind wheel arranged in the heat exchange air duct, and the wind wheel is used to drive the air flow; wherein the wind wheel can be a cross-flow wind wheel and is arranged on the air outlet side of the indoor heat exchanger. When the air conditioner indoor unit is working, the wind wheel drives the indoor air to flow, and drives the indoor air to enter the heat exchange air duct from the air inlet, and the flowing air flows to the air outlet after heat exchange in the indoor heat exchanger, and is sent out through the air guide frame 10.

[0032] In the embodiment of the present invention, Figures 1 to 5 As shown, the air conditioner indoor unit also includes: an air guide frame 10, which can be rotatably installed on the air outlet, and a mounting hole 11 is opened at the bottom of the air guide frame 10; a gear box 20, which is arranged below the air guide frame 10; a rotating member 30, which can be rotatably installed on the gear box 20, and the upper end of the rotating member 30 protrudes from the top of the gear box 20 and is fixedly matched with the mounting hole 11 to drive the air guide frame 10 to rotate; a plurality of bearings 40, the axes of the bearings 40 extend in the transverse direction, and the plurality of bearings 40 are arranged at intervals on the circumference of the rotating member 30; the bearing 40 includes an inner ring 41 and an outer ring 42 that can rotate relatively, the inner ring 41 is fixedly matched with the gear box 20, and the outer ring 42 abuts against the bottom of the air guide frame 10; or, the inner ring 41 is fixedly matched with the air guide frame 10, and the outer ring 42 abuts against the top of the gear box 20.

[0033] In this embodiment, the air guide frame 10 can be rotatably arranged at the air outlet of the indoor unit of the air conditioner, and the rotation axis of the air guide frame 10 extends longitudinally to change the air supply direction of the indoor unit of the air conditioner in the horizontal direction. The gear box 20 is used to support the air guide frame 10. Specifically, the gear box 20 includes a bottom shell and a top cover. The rotating member 30 is installed in the gear box 20, and the top of the rotating member 30 protrudes from the top cover to drive the air guide frame 10 to rotate after being fixedly matched with the air guide frame 10. The gravity of the air guide frame 10 will directly act on the rotating member 30. If the rotating member 30 contacts the gear box 20 to form friction resistance, the air guide frame 10 will increase the friction resistance. The bearing 40 can be a ball bearing 40, including an inner ring 41 and an outer ring 42 coaxially arranged, and the inner ring 41 and the outer ring 42 can rotate relative to each other under the action of the ball. The number of bearings 40 can be two, or three or more. If the number of bearings 40 is two, the two bearings 40 can be disposed on opposite sides of the circumference of the rotating member 30. The bearing 40 is disposed between the air guide frame 10 and the gear box 20. The installation method can be that the inner ring 41 of the bearing 40 is fixedly matched with the air guide frame 10, and the bottom of the outer ring 42 is in rolling contact with the gear box 20; or the inner cavity of the bearing 40 and the gear box 20 are fixed to the top of the gear box 20, and the top of the outer ring 42 is in rolling contact with the air guide frame 10.

[0034] If the inner ring 41 of the bearing 40 is fixed to the air guide frame 10, the gravity of the air guide frame 10 acts on the gear box 20 through the outer ring 42. Since the outer ring 42 and the gear box 20 are in rolling contact, the friction force generated between the outer ring 42 and the gear box 20 has little effect on the rolling of the outer ring 42, so that the air guide frame 10 can rotate smoothly. If the inner ring 41 of the bearing 40 is fixed to the top of the gear box 20, the gravity of the air guide frame 10 directly acts on the outer ring 42 of the bearing 40. Since the outer ring 42 and the air guide frame 10 are in rolling contact, the friction force between the air guide frame 10 and the outer ring 42 has little effect on the rolling of the outer ring 42, so that the air guide frame 10 can rotate smoothly. The two bearings 40 are arranged on both sides of the rotating member 30 in the circumferential direction and are coaxially arranged so that the rolling of the two outer rings 42 can support the rotation of the air guide frame 10, thereby improving the smoothness and stability of the rotation of the air guide frame 10.

[0035] The air conditioner indoor unit of the present invention arranges a plurality of bearings 40 between the air guide frame 10 and the gear box 20, and supports the rotation of the air guide frame 10 through the rolling contact between the outer ring 42 of the bearing 40 and the air guide frame 10 or the gear box 20, thereby avoiding direct contact and friction between the air guide frame 10 and the gear box 20, thereby improving the smoothness and stability of the rotation of the air guide frame 10 and reducing noise.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] Specifically, Figure 1 and Figure 2 As shown, the bottom of the air guide frame 10 is convexly provided with a mounting ring 12 which is arranged around the mounting hole 11, and the outer peripheral wall of the mounting ring 12 is convexly provided with a mounting column 121, and the mounting column 121 is fixedly matched with the inner ring 41, and the bottom of the outer ring 42 abuts against the top of the gear box 20. In this embodiment, the mounting ring 12 extends along the circumference of the mounting hole 11, and the mounting columns 121 are convexly arranged on the two opposite sides of the mounting ring 12, and the inner rings 41 of the two bearings 40 are fixedly matched with the mounting columns 121. After the rotating member 30 is matched with the mounting hole 11, the outer rings 42 of the two bearings 40 abut against the top of the gear box 20, thereby realizing the fixed installation of the bearings 40 and the air guide frame 10.

[0038] In practical applications, such as Figure 2 As shown, the bottom of the outer ring 42 protrudes from the bottom of the mounting ring 12, and the bottom of the air guide frame 10 is provided with a clearance groove 13 corresponding to the top of the outer ring 42. In this embodiment, the bottom of the outer ring 42 protrudes from the bottom of the mounting ring 12, which can prevent the mounting ring 12 from contacting the gear box 20, thereby making the rotation of the air guide frame 10 smoother. The clearance groove 13 can prevent the outer ring 42 from directly contacting the bottom of the air guide frame 10, so that the bottom of the outer ring 42 separates the air guide frame 10 and the gear box 20, and a gap is formed between the top of the outer ring 42 and the air guide frame 10, so that the rolling contact between the outer ring 42 and the gear box 20 can effectively support the rotation of the air guide frame 10, thereby improving the smoothness of the rotation of the air guide frame 10.

[0039] In one embodiment, if Figure 2 As shown, the outer peripheral wall of the mounting ring 12 is also provided with protective ribs 122 on both sides of the bearing 40 in the horizontal direction. In this embodiment, protective ribs 122 are provided on both sides of each bearing 40 in the horizontal direction, and the protective ribs 122 are used to ensure the stable rolling of the outer ring 42, reduce the obstruction of the rolling of the outer ring 42 caused by foreign matter, and further improve the stability of the rotation of the air guide frame 10. The protective ribs 122 can be integrally formed with the mounting ring 12 to improve the connection strength and production efficiency.

[0040] Specifically, Figure 1 and Figure 2As shown, the top of the gear box 20 is convexly provided with a guide ring 21 which is arranged around the rotating member 30, and the bearing 40 is located on the inner circumference of the guide ring 21. In this embodiment, the guide ring 21 extends along the circumference of the rotating member 30 to limit and guide the bearing 40 to prevent the bearing 40 from shifting during the rolling process. When the bearing 40 contacts the guide ring 21, the bearing 40 and the guide ring 21 are in line contact, which can reduce the impact on the rolling of the outer ring 42, and the outer ring 42 can naturally turn along the guide ring 21, thereby making the rotation of the air guide frame 10 more stable.

[0041] In one embodiment, a plurality of mounting shafts are provided on the top of the gear box 20, and the plurality of mounting shafts are arranged at intervals on the circumference of the rotating member 30, the inner ring 41 is fixedly matched with the mounting shaft, and the outer ring 42 abuts against the bottom of the air guide frame 10. In this embodiment, the axis of the mounting shaft extends in the lateral direction, and the inner ring 41 is fixedly matched with the mounting shaft, that is, the inner ring 41 is relatively fixed with the gear box 20. The outer ring 42 abuts against the bottom of the air guide frame 10, that is, the outer ring 42 is in rolling contact with the air guide frame 10, so that the bearing 40 can separate the air guide frame 10 and the gear box 20, and effectively support the rotation of the air guide frame 10, thereby achieving fixed installation of the bearing 40 and the gear box 20.

[0042] Specifically, the top of the outer ring 42 protrudes from the top of the rotating member 30, and a gap is formed between the bottom of the outer ring 42 and the top of the gear box 20. In this embodiment, the top of the outer ring 42 protrudes from the top of the rotating member 30, so that the gravity of the air guide frame 10 acts on the bearing 40 instead of the rotating member 30, thereby reducing the force load of the rotating member 30 and ensuring the stable rotation of the rotating member 30. The gap between the outer ring 42 and the gear box 20 can prevent the outer ring 42 from directly contacting the gear box 20, so that the outer ring 42 can roll smoothly.

[0043] In actual application, a guide ring is convexly provided at the bottom of the air guide frame 10 and is arranged around the mounting hole 11, and the bearing 40 is located on the inner circumference of the guide ring. In this embodiment, the guide ring extends along the circumference of the mounting hole 11 to limit and guide the bearing 40, so as to prevent the air guide frame 10 from being displaced relative to the bearing 40 during rotation. When the guide ring contacts the bearing 40, the bearing 40 and the guide ring are in line contact, which can reduce the influence on the rotation of the outer ring 42, thereby making the rotation of the air guide frame 10 more stable.

[0044] In one embodiment, if Figure 1 and Figure 2As shown, a mounting platform 14 is convexly provided at the bottom of the air guide frame 10, and the mounting hole 11 is opened on the mounting platform 14. In this embodiment, in combination with the embodiment of the mounting ring 12, the mounting ring 12 can be arranged around the mounting platform 14. The mounting platform 14 can increase the hole wall area of ​​the mounting hole 11, thereby increasing the matching area between the mounting hole 11 and the rotating member 30, so as to enhance the matching strength between the rotating member 30 and the air guide frame 10.

The specific structure of the air conditioner indoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
