[0050] Furthermore, the air duct cleaning assembly 10 includes an air duct wall 100, a driving member 200, a scraping member 300, a base 400, a cover plate 500, and an end plate 600. The air duct wall 100 is arranged on the base 400, and the air duct wall 100 and the base 400 are integrally formed. The integral forming process is simple and convenient to process, which improves the assembly efficiency and its structural strength; the driving member 200 is installed on the base 400 and is located on the side of the air duct wall 100 close to the evaporator, the scraping member 300 can be movably attached to the surface of the air duct wall 100, and the driving member 200 is connected to the scraping member 300 to drive the hanging sweeping member to move relative to the air duct wall 100; the cover plate 500 is arranged on the top of the driving member 200 to play a protective role; the end plate 600 is arranged on both sides of the air duct wall 100.

[0051] It should be noted that the air duct wall 100 is usually in an arc-shaped surface so as to better guide the airflow. The scraper 300 is in an arc-shaped strip that is adapted to the air duct wall 100 to ensure that the scraper 300 can be attached to the surface of the air duct wall 100. A brush 340 is provided on the side of the scraper 300 facing the air duct wall 100 so as to clean the air duct wall 100 through the brush 340.

[0052] Furthermore, the number of the scraping members 300 is at least two, and at least two scraping members 300 can be movably arranged on the air duct wall 100. The driving member 200 is connected to the at least two scraping members 300, and is used to drive the at least two scraping members 300 to move toward or away from each other synchronously along the length direction of the air duct wall 100 (direction A as shown in the figure) to clean the air duct wall 100.

[0053] In this embodiment, at least two scraping members 300 are arranged side by side along the length direction of the air duct wall 100 , and the arc-shaped extension length of the scraping members 300 is the same as the arc-shaped extension length of the air duct wall 100 .

[0054] By driving the driving member 200 at least two scraping members 300 simultaneously to move closer to or farther away from each other along the length direction of the air duct wall 100, the air duct wall 100 is cleaned. Therefore, the cleaning efficiency is high and the cleaning effect is significantly improved. Therefore, there is no need to disassemble the indoor unit 1 for cleaning, thereby improving the user experience and comfort.

[0055] Furthermore, the driving member 200 includes a motor 210 and two racks 220. A transmission wheel 230 is provided at the output end of the motor 210.
