[0032] In the embodiment provided by the present invention, the air guide portion 31 is an air guide hole 310, and the air guide device 30 further includes: a cylinder 32, the cylinder 32 has a through hole connected to the air outlet 20; a plurality of air guide holes 310 are arranged on the side wall of the cylinder 32, the plurality of air guide holes 310 are divided into a plurality of rows, and the plurality of rows of air guide holes 310 are arranged around the axis of the cylinder 32, so that the airflow in the cylinder 32 flows into the room through the plurality of air guide holes 310. Such an arrangement can make the air outlet of the indoor unit of the air conditioner more uniform and improve the comfort of the user.

[0033] Specifically, the air guide device 30 further includes: a rotating shaft 33, which is installed in the cylinder cavity of the cylinder 32, so that the vortex airflow flowing out of the air outlet 20 drives the cylinder 32 to rotate around the rotating shaft 33. Since condensed water is generated during the operation of the air conditioner, the present invention can use centrifugal force to throw out the condensed water on the cylinder 32 by rotatably setting the air guide device 30. When the condensed water is thrown out, the dust on the cylinder 32 can also be taken away, so that the air guide device 30 has a self-cleaning effect.

[0034] Preferably, the radial cross section of the air guide hole 310 is triangular. By guiding the air through the air guide hole 310 with a triangular radial cross section, the air can be made finer and denser, and the flow rate of the air flow can be increased to improve the air conditioning performance.

[0035] In the specific implementation process, the air conditioner indoor unit further includes: a support assembly 40, and the support assembly 40 is connected to the air guide device 30, so that the air guide device 30 is connected to the body 10 through the support assembly 40. At the same time, the support assembly 40 is used to support the air guide device 30, so that the air guide device 30 is more stable during operation.

[0036] In the embodiment provided by the present invention, the air guide device 30 includes a cylinder 32 and a rotating shaft 33 disposed in the cylinder 32, and the cylinder 32 has a through port communicating with the air outlet 20; the support assembly 40 includes: a transition piece 41, the transition piece 41 is hinged with the rotating shaft 33, so that the rotating shaft 33 is rotatably arranged around its axis; a support frame 42, the first end of the support frame 42 is connected to the transition piece 41, and the second end of the support frame 42 is connected to the body 10. The rotating shaft 33 and the support frame 42 are connected by the transition piece 41, so that the cylinder 32 can be rotated around the rotating shaft 33, and the air guide device 30 is connected to the body 10 at the same time.

[0037] Preferably, the transition piece 41 is a bearing, the inner ring of the bearing is connected to the rotating shaft 33, and the outer ring of the bearing is connected to the support frame 42. The transition piece 41 can also be a gear rack drive, a roller, a slide rail, etc., the first part of the transition piece 41 is connected to the support frame 42, and the second part of the transition piece 41 is connected to the rotating shaft 33.

[0038] In order to facilitate the installation of the transition piece 41 and prevent the transition piece 41 from coming off the rotating shaft 33, a mounting groove 330 is provided on the rotating shaft 33, and the transition piece 41 is connected to the rotating shaft 33 through the mounting groove 330.

[0039] In the specific implementation process, the support frame 42 includes a plurality of support rods, and the plurality of support rods are arranged around the transition piece. Preferably, the plurality of support rods are evenly arranged around the transition piece so that the airflow blown out from the air outlet is blown into the cylinder cavity of the cylinder body 32 more evenly.

[0040] In the embodiment provided by the present invention, an air duct is provided in the body 10, and the air duct is communicated with the air outlet 20; the air conditioner indoor unit further comprises: a controller 50, the controller 50 is connected to the air outlet assembly of the air conditioner indoor unit, and the air outlet assembly is provided in the air duct, so as to control the rotation direction of the air flow in the air duct through the controller 50, so as to control the rotation direction of the air guide device 30 rotating around the first predetermined axis. By changing the rotation direction of the air flow, the air guide device 30 is driven to change the rotation direction, and there is no need to separately set up a driving mechanism of the air guide device 30, which saves installation space and cost, reduces the noise of the air conditioner indoor unit, and can be removed when the air guide device 30 is not needed.

[0041] During the specific operation, the controller 50 is used to control the rotation direction of the air outlet group in the air-conditioning indoor unit to control the rotation direction of the air flow in the air duct. The controller 50 can be used to change the fan direction of the air outlet group at a fixed time. By changing the direction at any time node, the air flow convection direction is changed, so that the cylinder can spontaneously rotate clockwise and counterclockwise to achieve self-cleaning of the cylinder 32. For example, the clockwise rotating cylinder makes the dust and condensation water droplets attached to the surface have an acceleration along the tangent direction of the rotation plane. When the cylinder 32 changes direction and rotates counterclockwise, the water droplets can take away the dust. At this time, the dust and water droplets obtain an acceleration in the opposite direction. After the two accelerations cancel each other out, the dust and water droplets cannot maintain a relatively static state with the cylinder, so they will break away from the cylinder and fall into the room with the wind blown out of the air guide hole.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0043] The air conditioner indoor unit provided by the present invention comprises a body 10, an air outlet 20 and an air guide device 30, wherein the air outlet 20 is arranged at the top of the body 10, and the air flow in the body 10 flows into the room through the air outlet 20, and the air guide device 30 is installed at the top of the body 10, and a plurality of air guide parts 31 connected with the air outlet 20 are arranged on the air guide device 30, and the plurality of air guide parts 31 are arranged around the body of the air guide device 30, so that the air flow flows into the room through the plurality of air guide parts 31 after passing through the air outlet 20; wherein the air guide device 30 is rotatably arranged around a first predetermined axis.
