It can be understood that, by defining a receiving channel between the front end surface of the limiting plate 42 and the panel 7, which is suitable for the first connecting portion 51 to pass through, the up-and-down movement of the door opening and closing assembly 5 is facilitated, so that the first connecting portion 51 is facilitated to move up and down to be received or moved out of the receiving cavity. The size of the receiving channel is slightly larger than the thickness of the first connecting portion 51.

The stopper plate 42 is also provided with the vent hole 41.

In some embodiments of the present invention, as shown in fig. 10 and 11, the door opening and closing assembly 5 includes a flow dispersing module 6 having a wind dispersing function, the flow dispersing module 6 is disposed on the second connecting portion 52, and the flow dispersing module 6 includes: the air-conditioning device comprises a mounting plate 61 and an air-dispersing mechanism, wherein a plurality of first air outlet holes 611 which are arranged along the left-right direction are formed in the mounting plate 61, and the air-dispersing mechanism is arranged at the first air outlet holes 611.

The relative position between the blade of the movable blade 622 and the blade of the stationary blade 621 can be changed by controlling the rotation of the movable blade 622, so that the ventilation area of the first air outlet 611 can be adjusted, and the air outlet amount and the air outlet speed can be adjusted. When the indoor unit 100 of the air conditioner is operated and the door opening and closing assembly 5 is in the second position, the movable blade 622 may be controlled to rotate to a certain angle and then stop rotating, or the movable blade 622 may be controlled to rotate all the time.
