Description

Air deflector assembly and indoor unit with same

Technical Field

The invention relates to the technical field of air conditioning equipment, in particular to an air deflector assembly and an indoor unit with the same.

Background

The air supply quantity and the air supply angle of the indoor unit directly determine the thermal comfort of the indoor unit. 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.

If the first rocking bar 31 is an irregularly shaped rocking bar, the geometric center line of the first rocking bar 31 in the length direction is the geometric center line of the first connecting member 21 in the length direction. The arrangement enables the indoor unit to control the change of alpha according to different operation modes, and improves the heat exchange efficiency of the indoor unit.
