The air deflector is used as a core component of an air supply system of the indoor unit, and plays a very important role in improving the thermal comfort of the indoor unit.
In the prior art, the air supply angle of the indoor unit is limited due to the movement limitation of a single air guide plate or double air guide plate structure, so that the indoor unit has the problem of poor refrigerating and heating comfort. In the working process of the air conditioner, cold air or hot air blown out by the indoor unit through the air deflector is directly blown to a user, so that the use comfort of the user is reduced, meanwhile, the indoor unit cannot rapidly increase the temperature in a room in the heating process, and the heating efficiency of the air conditioner is reduced. In addition, in the prior art, the resistance loss of the air flow in the indoor unit in the flow guide process is large, so that the electric energy consumption required by the indoor unit to achieve the same refrigerating or heating effect is larger, and the use cost of a user is increased.
The prior art (CN111059748A) discloses an air guide device of an air conditioner. The air guide device adopts the push-out type air guide plate, and the air guide plate is provided with the air guide ribs, so that the air guide ribs guide airflow to flow along the required direction in the refrigeration or heating state of the air conditioner, and the use comfort level of a user is improved. However, the arrangement makes the structure of the air guide device very complex, and simultaneously increases the overall size of the air guide device, thereby affecting the overall length of the indoor unit and increasing the overall cost of the indoor unit.
In the prior art (CN209355454U), an air guide assembly of an air conditioner and an air conditioner are disclosed, in which the air guide assembly enlarges the air guide angle of an air guide plate, so that the air flow blown out by the air guide plate is more uniformly distributed in a room, and the use comfort of a user is improved. However, the air deflector adopts a rotating mode with a fixed radius, the moving mode is single, the arrangement limits the movable range of the rotating center of the air deflector, and the air deflector cannot move to the most appropriate refrigerating and heating position.

The indoor unit of claim 21 or 22, wherein when the air deflector (40) is located at the closed position, an included angle between a geometric centerline of the first connecting member (20) in the length direction and a geometric centerline of the first rocker (31) in the length direction is α 0, when the indoor unit is in the cooling mode, an included angle between a geometric centerline of the first connecting member (20) in the length direction and a geometric centerline of the first rocker (31) in the length direction is α 1, when the indoor unit is in the heating mode, an included angle between a geometric centerline of the first connecting member (20) in the length direction and a geometric centerline of the first rocker (31) in the length direction is α 2, where α 0< α 1< α 2.
24. Indoor unit according to claim 21 or 22, characterized in that the distance between the first rotation center (110) and the second rotation center (120) is obtained by the following formula:
wherein Y is the distance between the first rotation center (110) and the second rotation center (120);
L1is the length of the first crank (21);
L2is the length of the first rocker (31);
alpha is the included angle between the geometric center line of the first crank (21) in the length direction and the geometric center line of the first rocker (31) in the length direction.
