[0025] When the dust screen 3 in the return air frame 2 of the central air conditioner 1 needs to be cleaned, the electric slide rail 5 is started, and the electric slider 6 on the electric slide rail 5 starts to move under the command of the control system. Its moving path covers the entire dust screen 3 area, thereby realizing the automation of the cleaning work, reducing the need for manual intervention, and improving the cleaning efficiency and safety. When the cleaning process is completed, the operation of the electric slide rail 5 can be stopped.

[0026] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes a fixed block 9, a first clamping block 10, a first elastic member 11, a mounting block 12 and a collection frame 13. The fixed block 9 is fixedly connected to the bottom of the connecting frame 7. The mounting block 12 is slidably provided at the bottom of the fixed block 9. The left and right parts of the mounting block 12 are both slidably provided with the first clamping block 10. The first clamping block 10 is inserted into the fixed block 9. The first elastic member 11 is connected between the first clamping block 10 and the mounting block 12. The collection frame 13 is fixedly connected to the front and rear parts of the mounting block 12.

[0027] See also Figure 3 As shown, a guide plate 26 is also included. The collecting frame 13 is fixed with the guide plate 26, and the guide plate can guide the dust.

[0028] Before cleaning the return air interface, the two first clamping blocks 10 are pushed inward, and the first elastic member 11 is compressed accordingly. By clamping the two first clamping blocks 10 into the fixed block 9 and then releasing the first clamping block 10, the first elastic member 11 returns to its original state and drives the first clamping block 10 to be clamped on the fixed block 9. In this way, the collection frame 13 can be fixed on the fixed frame, so that the connecting frame 7 can drive the collection frame 13 to move together, so that the dust dropped during cleaning can be collected for easy cleaning.

[0029] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, it also includes a connecting plate 14, a dust collecting plate 15, a clamping plate 16, a first pull rope 17, a limit frame 18 and a second clamping block 19. The left side of the mounting frame 4 is rotatably provided with a connecting plate 14, and a dust collecting plate 15 is fixedly connected to the lower part of the connecting plate 14. The two dust collecting plates 15 are in contact with each other. The upper left part of the mounting frame 4 is symmetrically provided with a limit frame 18 by welding. The middle part of the mounting frame 4 is fixedly connected to a clamping plate 16, and a second clamping block 19 is arranged in the clamping plate 16. Two first pull ropes 17 are connected to the second clamping block 19, and the ends of the first pull ropes 17 are connected to the adjacent dust collecting plates 15.

[0030] See also Figure 6 and Figure 7 As shown, it also includes a guide frame 20, a scraper 21, a fixed plate 22, a second elastic member 23, a second pull rope 24 and a limit block 25. The left and right parts of the dust collecting plate 15 are fixedly connected to the guide frame 20, and the scraper 21 is slidably arranged between the two guide frames 20. The bottom of the dust collecting plate 15 is fixedly connected to the fixed plate 22, and the left and right parts of the fixed plate 22 are connected to the scraper 21 with a second elastic member 23. The bottom of the dust collecting plate 15 is fixedly connected to the limit block 25, and the middle and lower part of the scraper 21 is connected to the second pull rope 24, and the second pull rope 24 slides in the limit block 25.

[0031] See also Figure 5 As shown, a pulley 27 is also included. The pulley 27 is installed on the upper part of the limiting frame 18, and the first pull rope 17 slides on the pulley 27.

[0032] When cleaning the return air interface, the cleaning cotton 8 scrapes and cleans the dust screening plate 3, and the dust dropped during cleaning floats on the dust collecting plate 15; when the dust on the dust collecting plate 15 needs to be cleaned, the second card block 19 is inserted into the card slot at the lower part of the card plate 16, and the second card block 19 moves downward while pulling the pull rope, so that the pull rope pulls the dust collecting plate 15 to rotate, and then pulls the second pull rope 24 to drive the scraper 21 to move inward, and the second elastic member 23 is stretched accordingly. During the movement, the scraper 21 will contact the dust on the dust collecting plate 15 and push it into an easy-to-handle pile, thereby facilitating cleaning; after cleaning, the second pull rope 24 is loosened, and the second elastic member 23 drives the second pull rope 24 and the scraper 21 to reset, ready for the next use; the pulley can reduce the force required to pull the pull rope.
