Description

Air guide assembly, air conditioner indoor unit and air conditioner Technical Field The application relates to the technical field of air treatment equipment, in particular to an air guide assembly, an air conditioner indoor unit and an air conditioner. Background In the case of air conditioning systems, air guiding blades are usually provided at the outlet. The wind guide blade and the air outlet are in rotary connection, and the air supply direction is adjusted by changing the opening angle of the wind guide blade relative to the air outlet. The wind guide vanes are generally fixed in a local area of the air outlet, and are pulled by a pull rod to realize rotation, so that left and right wind sweeping or wind up and down swinging can be realized. Can also set up rotatable bearing structure in the air outlet department among the related art, set up wind-guiding blade on bearing structure, through the angle of control bearing structure relative air outlet, and then can further realize the control to the air supply angle, adapt to different room overall arrangement and user's demand, help reducing the air supply blind area, optimize the distribution of air current. In the traditional setting mode, the bearing structure is provided with a mounting groove, and the rotating shaft of the wind guide blade is inserted in the mounting groove. However, when air treatment equipment is in the air supply process, when needing to adjust the air supply angle, the wind-guiding blade can receive the impact force from the air current, leads to the frictional force between the rotation axis of wind-guiding blade and the mounting groove inner wall to increase, reduces wind-guiding blade pivoted smoothness, produces great rotation noise even, influences user experience. Disclosure of utility model In view of this, the application provides an air guide assembly, an air conditioner indoor unit and an air conditioner, which can improve the smoothness of rotation of air guide blades, avoid generating larger rotation noise and improve user experience. In order to achieve the above purpose, the application provides an air guide assembly, an air conditioner indoor unit and an air conditioner, which adopts the following technical scheme: in a first aspect, the present application provides an air guiding assembly comprising a load bearing structure and an air guiding blade; the bearing structure is provided with a mounting groove, and a first rotating piece is arranged in the mounting groove; The wind guide blade is provided with a connecting part, a second rotating piece is sleeved outside the connecting part, and the second rotating piece is rotatably arranged inside the first rotating piece; The first rotating member is arranged at intervals with the second rotating member, a plurality of rolling members are arranged between the first rotating member and the second rotating member, the plurality of rolling members are arranged on the outer side of the second rotating member in a ring mode, and the second rotating member is in rolling contact with the first rotating member through the rolling members. Through the technical scheme, the sliding friction between the traditional wind guide vane rotating shaft and the inner wall of the mounting groove is converted into rolling friction. The rotational resistance is significantly reduced. The plurality of rolling elements are annularly arranged on the outer side of the second rotating element, and can uniformly bear load, so that local stress concentration is avoided, and friction loss is further reduced. The first rotating piece and the second rotating piece are arranged at intervals, and are indirectly contacted through the rolling piece, so that direct rigid friction between the rotating shaft and the mounting groove in the traditional structure is avoided. Even if the wind guide blade is offset due to the impact of air flow, the rolling piece can still maintain smooth rolling, the rotation continuity is ensured, and the clamping stagnation or shaking phenomenon caused by external force is reduced. The contact area between the wind guide blade and the inner wall of the mounting groove is reduced, and the noise generated by rolling friction is far lower than sliding friction, so that abnormal sound generated by friction increase in the traditional structure can be effectively avoided. In one possible implementation manner, the air guiding assembly provided by the application, the first rotating member comprises an annular main body and a lap joint part; The annular main body is positioned in the mounting groove; The overlap joint portion with the annular main part is kept away from the one end of mounting groove diapire is connected, the overlap joint portion is located outside the mounting groove, just the overlap joint portion can with bearing structure butt. Through the technical scheme, double supports are formed, the axial displacement of the first rotating piece in the mounting gro
