The following embodiments are used to illustrate the present utility model.

[0029] A dust removal structure for an outdoor heat exchanger of an air conditioner, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, includes the main body 10 of the heat exchanger frame, and the main body 10 of the heat exchanger frame is fixedly arranged on the ground; a reciprocating cleaning structure, the reciprocating cleaning structure is fixedly arranged in the main body 10 of the heat exchanger frame, the reciprocating cleaning structure includes a reciprocating structure and a cleaning and dust removal assembly, the reciprocating structure includes a support frame 11, a first gear 14, a second gear 15, a crank 19, a connecting rod 20, a sector gear 21 and a sliding rack 22, the support frame 11 is fixedly arranged in the main body 10 of the heat exchanger frame, the first gear 14, the second gear 15, the crank 19 and the sector gear 21 are all rotatably arranged in the support frame 11, the same connecting rod 20 is rotatably arranged between the crank 19 and the sector gear 21, and the sliding rack 22 is slidably arranged in the support frame 11; the cleaning and dust removal assembly includes a rotating brush 13 and a horizontal brush 23, the rotating brush 13 is rotatably arranged on one side of the support frame 11, the rotating brush 13 is fixedly connected to the first gear 14 and the second gear 15, the horizontal brush 23 is slidably arranged above the support frame 11, and the horizontal brush 23 is fixedly connected to the sliding rack 22.

[0030] The working principle is as follows. The reciprocating cleaning structure is arranged inside the heat exchanger frame body 10. By setting the reciprocating cleaning structure, the rotation of the crank 19 drives the connecting rod 20, causing the connecting rod 20 to push the sector gear 21 to rotate. The sector gear 21 meshes with the second gear 15 to rotate, and the second gear 15 drives the first gear 14 to rotate. The meshing of the sliding rack 22 with the first gear 14 will simultaneously cause the horizontal brush 23 to perform horizontal dust removal on the top surface of the heat exchanger frame body 10. At the same time, the rotation of the first gear 14 and the second gear 15 will cause the rotating brush 13 to rotate for dust removal. The two cleaning methods of rotation and horizontal can reduce the occurrence of dead corners, thereby avoiding the accumulation of dust in dead corners and reducing energy consumption. By using the cooperation of the crank 19 and the connecting rod 20 to push the rotation of the sector gear 21, since the rotation angles of the first gear 14 and the second gear 15 need to be determined according to the movement of the sector gear 21, in this process, the rotating brush 13 will achieve a reciprocating rotation cleaning form under the drive of the first gear 14 and the second gear 15. At this time, the rotating brush 13 performs rotating dust removal on the inner side of the heat exchanger frame body 10. At the same time, the horizontal brush 23 realizes a horizontal reciprocating cleaning mode under the meshing and sliding of the sliding rack 22 and the first gear 14. At this time, the horizontal brush 23 performs horizontal dust removal on the top side of the heat exchanger frame body 10. The rotating brush 13 and the horizontal brush 23 jointly perform dust removal cleaning from two adjacent directions, which can perform more perfect and comprehensive dust removal on the surface of the heat exchanger frame body 10, thereby achieving an ideal dust removal effect and improving the heat exchange effect of the air conditioner.

[0031] As Figure 2 shown, the support frame 11 is composed of a U-shaped bracket and an L-shaped plate. One side of the U-shaped bracket is fixedly connected with a support block 12, and the support block 12 and the L-shaped plate are symmetrically arranged with the U-shaped bracket as the midpoint; As Figure 2 and Figure 3 shown, a through hole is opened inside the U-shaped bracket, and a rotating column is movably penetrated through the through hole. A first gear 14 and a second gear 15 are fixedly connected to the curved surface of the rotating column. The first gear 14 and the second gear 15 are located inside the U-shaped bracket, and one end of the rotating column is fixedly connected with the rotating brush 13; As Figure 2 and Figure 4 shown, a rotating hole is opened inside the support block 12, and a cylinder is rotatably connected through a bearing in the rotating hole. One side of the support block 12 away from the rotating brush 13 is fixedly provided with a motor 18 through a bracket, and the output end of the motor 18 is connected to one end of the cylinder; As Figure 3 and Figure 4 shown, a blocking block 17 is fixedly provided on one side of the L-shaped plate away from the rotating brush 13. A short column is provided on the opposite side of the blocking block 17 connected to the L-shaped plate. A circular hole is opened at the center of the sector gear 21, and the circular hole is rotatably connected to the short column through a bearing. The sector gear 21 is in transmission meshing with the second gear 15; As Figure 2 、 Figure 3 、 Figure 4 andFigure 5 As shown in the figure, a sliding card slot 16 is provided on the inner top surface of the support frame 11. The sliding rack 22 is composed of a sliding bar and a rack. The sliding bar slides in the sliding card slot 16, and the rack is in transmission engagement with the first gear 14. U-shaped plates are fixedly connected to both ends of the sliding rack 22, and the same horizontal brush 23 is fixedly connected to the top surfaces of the two U-shaped plates; as Figure 2 and Figure 4 shown, a through hole is provided at one end of the crank 19, and a shaft column is fixedly connected to the other end of the crank 19. Circular holes are provided at both ends of the connecting rod 20. The through hole is fixedly connected to the curved surface of the rotating column. The crank 19 is arranged between the support block 12 and the motor 18. Another rotating column is fixedly provided on the side of the sector gear 21 away from the abutting block 17. One of the circular holes is rotatably connected to the rotating column, and the other circular hole is rotatably connected to the shaft column. The connecting rod 20 is rotatably arranged between the crank 19 and the sector gear 21.

[0032] The specific implementation method is as follows. Start the motor 18. The motor 18 drives the cylinder to rotate, and the cylinder drives the crank 19 to rotate. At this time, the crank 19 pulls the connecting rod 20, and the connecting rod 20 pulls the rotating column. At this time, the sector gear 21 moves along with the movement of the connecting rod 20. At this time, the sector gear meshes with the second gear 15, and the rotation of the second gear 15 will cause the first gear 14 on the rotating column to rotate synchronously. At this time, the first gear 14 meshes and drives the sliding rack 22. At this time, the sliding rack reciprocally slides in the sliding card slot 16. Under the movement of the sliding rack 22, the horizontal brush 23 will move synchronously. At this time, the horizontal brush 23 performs dust removal and cleaning on the inner top surface of the heat exchanger frame body 10. In this process, the rotating brush 13 connected to one end of the rotating column will rotate synchronously in the rotation direction of the second gear 15. At this time, the rotating brush 13 performs rotating dust removal on the inner wall surface of the heat exchanger frame body 10. At this time, the wall surfaces cleaned by the rotating brush 13 and the horizontal brush 23 are adjacent wall surfaces. After the dust removal is completed, turn off the motor 18 to achieve reset.
