[0113] Reference Fig.16 and Fig.17 According to some embodiments of the present invention, the mounting structure 346 includes two mounting members 348 that are opposite to each other and spaced apart from each other. The mounting members 348 extend in the up-down direction. A slide groove 347 is formed on the mounting member 348 or a slide groove 347 is defined between the mounting member 348 and the side plate 34. The second filter screen 32 is mounted between the two mounting members 348. The mounting member 348 can limit the second filter screen 32 in the front-to-back direction.

The second filter screen 32 may be inserted from top to bottom into the slide groove 347 defined between the mounting member 348 and the side panel 34 to complete the assembly of the second filter screen 32 on the side panel 34.

[0116] Reference Fig.17 According to some embodiments of the present invention, a support flange 349 is formed on the bottom surface of the side plate 34, and the bottom of the second filter 32 is supported on the support flange 349. The support flange 349 can enhance the overall structural strength of the side plate 34, and can limit the assembly of the second filter 32. After the second filter 32 is assembled in place, the support flange 349 can support the second filter 32, and can prevent the second filter 32 from falling from the bottom of the side plate 34, thereby enhancing the stability and reliability of the cooperation between the second filter 32 and the side plate 34.

[0117] For example, when installing the second filter 32, the second filter 32 is inserted into the slide groove 347 from top to bottom. When the bottom of the second filter 32 is against the supporting flange 349, the second filter 32 cannot continue to move downward, which can ensure that the second filter 32 is assembled in place and complete the installation process of the second filter 32.

[0118] Reference Fig.16 and Fig.23According to some embodiments of the utility model, the mounting member 348 includes a fixing portion 350 and a limiting portion 351, wherein the limiting portion 351 is connected to a side of the fixing portion 350 close to the second filter screen 32, the fixing portion 350 is connected to the side plate 34, and a slide groove 347 is defined between the limiting portion 351 and the side plate 34; the limiting portion 351 includes a first limiting rib plate 352 and a second limiting rib plate 353, wherein the first limiting rib plate 352 is opposite to the side of the second filter screen 32 in the front-to-back direction, and the second limiting rib plate 353 is opposite to the side plate 34 in the left-to-right direction and is located on a side of the second filter screen 32 away from the side plate 34.

The limiting portion 351 can prevent the second filter screen 32 from tipping over, thereby enhancing the stability of the cooperation between the second filter screen 32 and the side plate 34.

Since the top of the second limiting rib 353 is lower than the top of the first limiting rib 352, the second filter screen 32 can be inserted into the position limited by the first limiting rib 352 in the front-to-back direction. At this time, the second filter screen 32 is limited in the front-to-back direction, but not in the left-to-right direction. The second filter screen 32 can be inserted into the slide groove 347 with a relatively small force, and the second filter screen 32 can be continued to be inserted downward. When at least a part of the second filter screen 32 is located at the position limited between the second limiting rib 353 and the side plate 34, the second filter screen 32 is limited in the front-to-back and left-to-right directions, and the space of the slide groove 347 is more compact, and a greater force is required to continue to insert the second filter screen 32 downward into the slide groove 347.

[0123] Compared with the top of the second limiting rib 353 being flush with the top of the first limiting rib 352, the top of the second limiting rib 353 is lower than the top of the first limiting rib 352. When the second filter screen 32 is located on the first limiting rib 352 and is not opposite to the second limiting rib 353, the second filter screen 32 can be installed on the side panel 34 with relatively small force, and the second filter screen 32 can be prevented from being stuck during the assembly process due to the long slide groove 347, thereby making the assembly of the second filter screen 32 smoother during the overall assembly process of the second filter screen 32.

[0144] The installation process of the second filter 32 is as follows: the user holds the handle 327, with the guide slope 326 of the second filter 32 facing downward, and inserts the second filter 32 into the slide groove 347 from top to bottom. When the bottom of the second filter 32 abuts against the supporting flange 349, the second filter 32 cannot move further downward, and the installation of the second filter 32 on the side panel 34 is completed.

[0145] The disassembly process of the second filter 32 is as follows: remove the side panel 34 of the rear shell component 3 of the casing 1, and the user holds the handle 327 to pull the second filter 32 out of the slide groove 347 from bottom to top, so that the bottom of the second filter 32 is released from the support flange 349, and continues to pull the second filter 32 upward. When the bottom of the second filter 32 is detached from the slide groove 347, the disassembly of the second filter 32 on the side panel 34 is completed.

[0146] When the air-conditioning indoor unit 100 is working, the wind wheel 512 drives the airflow to enter through the first air inlet 21, the second air inlet 31 and the third air inlet respectively, and after the airflow of the first air inlet 21, the second air inlet 31 and the third air inlet is filtered by the first filter net, the second filter net 32 ​​and the third filter net respectively, the filtered airflow flows into the air duct volute 51 through the air flow inlet 511, and the wind wheel 512 drives the airflow to flow to the heat exchanger component 52 through the air flow outlet. The airflow exchanges heat when flowing through the heat exchanger component 52, and the airflow after heat exchange is blown into the room through the air outlet 252 to heat up or cool down the room.
