In any connection mode, the first air deflector 8 and the second air deflector 9 are required to be connected with a driving motor. Similar to the operation of the first and second swing plates 7 and 10, the first and second air deflectors 8 and 9 may be individually connected to the motor, or may be linked by a transmission mechanism, which is not described herein again, and an embodiment in which the motor is individually connected is preferred.

In order to ensure that the first swing plate 7 and the second swing plate 10 do not interfere with other parts in the swing process and the sealing performance of the air duct 6 can be ensured, the length of the first swing plate 7 is set to be equal to the distance between the pivot center of the first swing plate 7 and the pivot center of the second air deflector 9, and the length of the second swing plate 10 is set to be equal to the distance between the pivot center of the second swing plate 10 and the pivot center of the second air deflector 9, so that the position relation similar to an equilateral triangle can be realized, and the sealing performance and the interference-free requirements can be met at the same time.

The following describes the adjustment process of the air duct 6 in the present invention in detail.

When the indoor unit of the air conditioner is in the cooling mode, according to the characteristics of the cold air itself, it can be understood by those skilled in the art that if the cold air is conveyed toward the space in front of the indoor unit to form a parabolic track, the conveying effect is much better than that of the cold air conveyed directly toward the lower side of the indoor unit. Referring to fig. 2, the first swing plate 7 is swung counterclockwise to be overlapped with the pivot center of the second air deflector 9, the first air deflector 8 is closed, the second air deflector 9 is opened, and cold air can be conveyed towards the front of the indoor unit as far as possible, so that waterfall type air supply of the cold air can be formed, the diffusion range and the diffusion time of the cold air are increased, the cold air can be uniformly diffused into the room, and all parts in the room can be uniformly cooled. If the indoor unit of the air conditioner is in a heating mode, the first swing plate 7 is controlled to swing clockwise to be overlapped with a pivoting center of the first air deflector 8, the first air deflector 8 is opened, the second air deflector 9 is closed, and the second swing plate 10 is controlled to swing to be overlapped with the pivoting center of the second air deflector 9, so that hot air is conveyed vertically downwards, the hot air moves downwards firstly under the influence of density and then moves upwards, the vertical downward conveying can increase the diffusion time and diffusion path before the hot air rises to a roof, and the hot air is diffused fully indoors. If a soft wind mode is to be realized, the first swing plate 7 can be swung to be in lap joint with the pivot center of the first air guide plate 8, the second swing plate 10 is swung anticlockwise to be abutted against the shell 1, and the first air guide plate 8 and the second air guide plate 9 are both opened, so that the air outlet sectional area of the air channel 6 is increased, the air speed can be reduced, large-range air outlet is realized, and the soft wind mode is realized. If the air outlet direction is fixed in a certain direction, the opening and closing angles of the swing plate and the air guide plate can be controlled simultaneously, and air outlet adjustment at various angles is realized.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
