[0032] Embodiment 3

[0033] Refer to Figures 2 - 4 and, on the basis of Embodiment 1 and Embodiment 2, it is further obtained that the second fixing mechanism 6 includes a fixing cylinder 602. A slider 603 is slidably connected inside the fixing cylinder 602. One end of the slider 603 is fixedly provided with a wedge-shaped clamping block 604. A clamping groove 605 adapted to the wedge-shaped clamping block 604 is formed on the central air conditioner box body 1. The other end of the slider 603 is fixedly connected with a guide rod 606. A second spring 607 is sleeved on the guide rod 606. The fixing cylinder 602 is fixedly provided at the side end of the top cover 5. An installation chute 601 is formed on the top cover 5. The installation chute 601 is slidably connected with the upper end of the central air conditioner box body 1.

[0038] When it is necessary to maintain the ventilation assembly 3, by rotating the rotating block 411 again, the clamping rod 406 is disengaged from the clamping hole 402 to release the locking and fixing of the frame 31. Then, the frame 31 can be taken out from the installation groove 23 to complete the quick disassembly of the ventilation assembly 3, which is convenient for the maintenance operation of the ventilation assembly 3. When it is necessary to remove the top cover 5, by pulling the pull ring 609 outwards, the wedge-shaped clamping block 604 is disengaged from the clamping groove 605 to release the locking and fixing of the top cover 5. Then, the top cover 5 can be slid out from the central air-conditioning box body 1 by using the installation sliding groove 601.
