At this time, the cover plate is connected to the front panel and blocks the opening, thereby reducing the probability of dust, insects and ants entering the accommodating cavity, thereby reducing the impact of foreign matter entering the sub-accommodating cavity on the operation of the sub-machine, and ensuring the stability and safety of the sub-machine operation while ensuring the consistency of the appearance of the air-conditioning indoor unit; in the avoidance state, the top and bottom ends of the cover plate move upward to the top of the first sliding section and the top of the second sliding section respectively, and at the same time drive the cover plate to move in the direction of the back ion accommodating cavity, so that the cover plate can be covered on the outer surface of the front panel and avoid the opening. At this time, the sub-machine can be moved or moved out of the sub-accommodating cavity.

[0057] Optionally, the length of the first sliding section 311 matches the height of the cover plate 40 in the vertical direction; the length of the second sliding section 312 matches the height of the cover plate 40 in the vertical direction.

[0058] In this way, the covering effect of the cover 40 on the opening 130 can be ensured in the covering state to avoid. At the same time, it can also be ensured that when the cover 40 switches between the avoidance state and the covering state, the cover 40 completely opens the opening 130 to avoid the cover 40 blocking the movement of the sub-machine 20 in or out.

[0059] Optionally, the air-conditioning indoor unit also includes a first connecting member 51 and a second connecting member 52; the first connecting member 51 is arranged at the top end of the cover plate 40, including a first connecting shaft 511 and a first connecting arm 512 extending radially along the first connecting shaft 511, the first end of the first connecting shaft 511 is inserted in the corresponding first sliding section 311, and the first connecting arm 512 is connected to the corresponding top corner of the cover plate 40; the second connecting member 52 is arranged at the bottom end of the cover plate 40, including a second connecting shaft 521 and a second connecting arm 522 extending radially along the second connecting shaft 521, the first end of the second connecting shaft 521 is inserted in the corresponding second sliding section 312, and the second connecting arm 522 is connected to the corresponding bottom corner of the cover plate 40.

[0060] Optionally, the cover plate 40 includes a top angle and a bottom angle corresponding to the first side edge 131 , and also includes a top angle and a bottom angle corresponding to the second side edge 132 .

[0061] Optionally, the first connecting shaft 511 and the second connecting shaft 521 are both constructed as cylindrical connecting shafts to reduce the friction of the first connecting shaft 511 sliding up and down along the first sliding section 311 and reduce the friction of the second connecting shaft 521 sliding up and down along the second sliding section 312 .

[0062] Specifically, the first ends of the two first connecting shafts 511 are respectively inserted into the corresponding first sliding sections 311, and the two first connecting arms 512 are respectively fixedly connected to the corresponding top corners of the cover plate 40; the first ends of the two second connecting shafts 521 are respectively inserted into the corresponding second sliding sections 312, and the two second connecting arms 522 are respectively fixedly connected to the corresponding bottom corners of the cover plate 40.
