The top air outlet mechanism can be arranged at the top of an indoor unit of the air conditioner in a vertically movable mode, when the top air outlet mechanism moves back to the top of the air conditioner downwards, the top air outlet mechanism is closed, after the top air outlet mechanism moves upwards, the top air outlet mechanism is opened, and at the moment, air can be supplied through the top air outlet of the top air outlet mechanism.
Referring to fig. 3 and 4, an indoor unit of an air conditioner (i.e., an indoor unit of an air conditioner) is provided with a first air duct 1, a first air duct motor 11 (i.e., an axial flow motor), a second air duct 2, a second air duct motor 21 (i.e., a centrifugal fan), a third air duct 3, and an evaporator 4. The first air duct 1 is positioned vertically above the second air duct 2; the third air duct 3 is located vertically above the second air duct 2, and the evaporator 4 is located behind the first and second air ducts.
As shown in fig. 6, the air guide mechanism J of the indoor unit 1000 of the air conditioner further includes: and an air outlet frame F. The air outlet frame F comprises a rear plate F1, and a ventilation hole F4 is formed in the rear plate F1.

Further, as shown in fig. 8, a mounting hole N221 is provided in the peripheral wall of the fixed ring N22, and one end of the stationary blade N1 passes through the mounting hole N221 and is rotatable in the mounting hole N221. That is, the installation hole N221 is provided to rotatably connect one end of the stationary vane N1 with the stationary ring N22, so that one end of the stationary vane N1 can be relatively rotated in the installation hole N221.
In some alternative embodiments, as shown in fig. 8, the blade driving plate N3 is sleeved outside the outer ring N21, wherein the outer ring N21 is provided with a mounting groove N212, and the stator blade N1 is supported in the mounting groove N212. It can be understood that the blade driving plate N3 is sleeved outside the outer ring N21, so that the outer ring N21 can limit the position of the blade driving plate N3.

One end of the blade N10 is connected with the fixed ring N22, and the other end of the blade N10 is provided with a sleeve N101. A first end of the piston shaft N12 is connected to the vane drive plate N3 and a second end of the piston shaft N12 is telescoped within the sleeve N101 to move the vane N10 between the first and second positions. That is, the first end of the piston shaft N12 is driven by the vane driving plate N3 to rotate relatively, so that the second end of the piston shaft N12 can telescope to drive the other end of the vane N10 to rotate, one end of the vane N10 rotates along with the other end of the vane N10 relative to the fixing ring N22, and the whole vane N10 can move between the first position and the second position.
Specifically, as shown in fig. 9, the first end of the piston shaft N12 is connected to the blade driving plate N3 by a ball joint. It can be understood that the arrangement of the spherical hinge enables the rotation between the first end of the piston shaft N12 and the blade driving plate N3 to be more flexible, and the air guide range of the blade N10 can be expanded.
