This can improve the structural strength of the mounting opening 123 and avoid problems such as deformation of the mounting opening 123. Moreover, the limiting rib 129 has a simple structure and is easy to process and manufacture.

[0124] At the same time, such as Figure 15 As shown, one end of the first stiffening plate 81 in the width direction is connected to the box body 10 through the connection with the first extension 13 and the second extension 14. This connection between the first stiffening plate 81 and the box body 10 ensures good structural strength and avoids appearance defects at the connection between the outer wall of the box body 10 and the first stiffening plate 81. This facilitates the molding of the rear box component 100, effectively reduces appearance defects, improves production yield, and reduces manufacturing costs.

[0125] In some embodiments, such as Figure 3 As shown, the rear housing component 100 includes a filter screen 20, which includes a filter screen body 21.

[0127] In some embodiments, such as Figure 5 As shown, multiple filters 20 are spaced apart in the vertical direction (two or more). Each filter 20 is opposite to the air inlet 11 of the air conditioner 200. Multiple filters 20 facilitate the filtration of airflow entering from the air inlet 11, and each filter 20 can be installed, removed, and cleaned individually, making installation, removal, and cleaning more convenient. Furthermore, multiple mounting ports 123 are spaced apart in the vertical direction, allowing for the assembly of multiple filters 20 individually, meeting the installation requirements of the filters 20.

[0128] The air conditioner 200 according to an embodiment of the present invention includes a rear housing component 100 according to an embodiment of the present invention. Since the rear housing component 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the air conditioner 200 according to an embodiment of the present invention, through the reinforcement 80 disposed on the inner sides of both ends of the housing body 10 in the width direction, the reinforcement 80 extends along the height direction of the housing body 10, the first stiffener 81 is connected to the housing body 10, one end of the second stiffener 82 in the width direction and one end of the third stiffener 83 in the width direction are both connected to the first stiffener 81, and the other ends of the second stiffener 82 in the width direction and the third stiffener 83 in the width direction both extend towards the other end of the housing body 10 in the width direction. The second stiffener 82 is located in front of the third stiffener 83, forming two layers of reinforcement, resulting in high structural strength of the reinforcement 80, effectively enhancing the structural strength of the housing body 10 in the width and height directions, which is beneficial to improving the structural strength of the rear housing component 100, and facilitating molding and manufacturing, ensuring mold forming stability, and reducing processing costs.

[0129] In some embodiments, such as Figures 1-3 As shown, the air conditioner 200 also includes a top cover 63, a panel assembly 64, and a chassis 65.
