[0044] like Figure 4 and Figure 5 As shown, a first reinforcing rib 31 is provided on the side of the decorative panel 3 facing the face frame 1, and the chassis assembly 4 is arranged in the face frame 1 and abuts against the first reinforcing rib 31. The impact force suffered by the decorative panel 3 during the impact on the left and right sides of the air-conditioning indoor unit 100, the drop of the air-conditioning indoor unit 100, and the drop test of the air-conditioning indoor unit 100 can be transmitted to the end cover 2 and transmitted to the chassis assembly 4 through the first reinforcing rib 31. The impact force on the end cover 2 can be transmitted to the face frame 1, which can increase the force transmission effect between the decorative panel 3, the end cover 2 and the chassis assembly 4, avoid stress concentration, and avoid cracking of the decorative panel 3 and the end cover 2 during the impact on the left and right sides of the air-conditioning indoor unit 100, the drop of the air-conditioning indoor unit 100, and the drop test of the air-conditioning indoor unit 100.

[0045] like Figure 1 As shown, the chassis assembly 4 includes a chassis body 41 and a chassis cover 42. The two chassis covers 42 are respectively arranged at the two ends of the air-conditioning indoor unit 100 in the left and right directions and are arranged in sequence with the decorative panel 3, the end cover 2 and the face frame 1.

[0046] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, by respectively clamping the two end covers 2 at the two ends of the face frame 1 in the left and right directions, the decorative panel 3 is connected to the end cover 2, and the side of the decorative panel 3 facing the face frame 1 is provided with a first reinforcing rib 31 and the first reinforcing rib 31 is in contact with the chassis assembly 4. When the left and right sides of the air-conditioning indoor unit 100 are impacted, the air-conditioning indoor unit 100 falls, and the air-conditioning indoor unit 100 is subjected to a drop test, the impact force suffered by the decorative panel 3 can be transmitted to the end cover 2 and transmitted to the chassis assembly 4 through the first reinforcing rib 31, and the impact force on the end cover 2 can be transmitted to the face frame 1, which can increase the force transmission effect between the decorative panel 3, the end cover 2 and the chassis assembly 4, avoid stress concentration, and avoid cracking of the decorative panel 3 and the end cover 2 when the left and right sides of the air-conditioning indoor unit 100 are impacted, the air-conditioning indoor unit 100 falls, and the air-conditioning indoor unit 100 is subjected to a drop test.

[0047] In addition, if Figure 1 As shown, the air conditioner indoor unit 100 further includes a panel 5, an air guide plate 6 and an evaporator 7, the panel 5 is connected to the face frame 1, the air guide plate 6 is connected to the face frame 1, and the evaporator 7 is arranged in the chassis assembly 4. It should be noted that the panel 5, the air guide plate 6 and the evaporator 7 are prior art for ordinary technicians in this field, and will not be described in detail here.

[0048] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the first reinforcing rib 31 is arranged at the upper and lower ends of the decorative plate 3 and close to the rear end of the air-conditioning indoor unit 100. It can be understood that the main structure of the face frame 1 wraps the front and upper and lower surfaces of the air-conditioning indoor unit 100, and the strength of the rear end of the air-conditioning indoor unit 100 is relatively low. The first reinforcing rib 31 is arranged at the upper and lower ends of the decorative plate 3 and close to the rear end of the air-conditioning indoor unit 100, which can increase the strength of the rear end of the air-conditioning indoor unit 100, and prevent the left and right sides of the air-conditioning indoor unit 100 from being impacted, the air-conditioning indoor unit 100 from falling, and the decorative plate 3 and the end cover 2 from cracking during the drop test of the air-conditioning indoor unit 100.

[0049] It is understood that in the front-to-back direction (such as Figure 2 In the front-to-back direction shown in the figure), for example, on the left side of the air-conditioning indoor unit 100, the rear edge of the end cover 2, the rear edge of the decorative panel 3 and the rear edge of the chassis assembly 4 are arranged in sequence, and the first reinforcing rib 31 is close to the rear edge of the decorative panel 3. The raised free end surface of the first reinforcing rib 31 can stop against the chassis assembly 4, so as to facilitate the transmission of force between the decorative panel 3 and the chassis assembly 4.

[0050] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the first reinforcing rib 31 includes a plurality of first sub-reinforcing ribs 311 and a plurality of second sub-reinforcing ribs 312 , and the plurality of first sub-reinforcing ribs 311 and the plurality of second sub-reinforcing ribs 312 are alternately arranged.

[0051] In this embodiment, there are multiple first sub-reinforcement ribs 311, and the first sub-reinforcement ribs are arranged along the up and down directions of the air conditioner indoor unit 100 (such as Figure 1 The decorative panel 3 has a plurality of first and second reinforcing ribs 311 and 312, and the first and second reinforcing ribs 312 are arranged at intervals along the front-to-back direction of the air-conditioning indoor unit 100. The first and second reinforcing ribs 311 and 312 intersect with each other, so that the impact force on the decorative panel 3 can be transmitted along the front-to-back direction and the up-down direction of the air-conditioning indoor unit 100. The decorative panel 3 has more force transmission paths, which can increase the strength of the rear end of the air-conditioning indoor unit 100, and avoid the left and right sides of the air-conditioning indoor unit 100 from being impacted, the air-conditioning indoor unit 100 from falling, and the decorative panel 3 and the end cover 2 from cracking during the drop test of the air-conditioning indoor unit 100.

[0052] In some embodiments of the present invention, Figure 6 and Figure 8 As shown, the end cover 2 includes a plate body 21 and a matching plate 22, the matching plate 22 is connected to the edge of the plate body 21, the matching plate 22 covers the left and right ends of the face frame 1, the matching plate 22 has more contact surfaces with the face frame 1, and the matching between the end cover 2 and the face frame 1 is more reliable. The outer surface of the matching plate 22 exposed to the outside of the air conditioner indoor unit 100 is flush with the outer surface of the face frame 1 exposed to the outside of the air conditioner indoor unit 100, which can make the outside of the air conditioner indoor unit 100 smoother, avoid bulges on the outside of the air conditioner indoor unit 100, and avoid scratches on users or assembly and maintenance workers.

[0053] Furthermore, if Figure 6-Figure 10 As shown, the plate body 21 has a matching plate 22 at least at both ends of the upper and lower directions, and the end cover 2 also includes a second reinforcing rib 23. The upper and lower ends of the end cover 2 have the second reinforcing rib 23, and the second reinforcing rib 23 is arranged at the connection 27 between the matching plate 22 and the plate body 21 and extends to the matching plate 22 and the plate body 21. The second reinforcing rib 23 can strengthen the strength of the plate body 21 and the matching plate 22, prevent the left and right sides of the air-conditioning indoor unit 100 from being impacted, the air-conditioning indoor unit 100 from falling, and the connection position between the matching plate 22 and the plate body 21 from cracking during the drop test of the air-conditioning indoor unit 100, thereby increasing the strength of the end cover 2.

[0054] In some embodiments of the utility model, the wall thickness of the plate body 21 at the position where the second reinforcing rib 23 is provided is 2.5-4mm. It is understandable that the wall thickness of the plate body 21 at the position where the second reinforcing rib 23 is provided can be 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm or 4mm. The wall thickness of the plate body 21 at the position where the second reinforcing rib 23 is provided is not less than 2.5mm, which can ensure the strength of the plate body 21 at the position where the second reinforcing rib 23 is provided, and avoid breakage when subjected to impact; the wall thickness of the plate body 21 at the position where the second reinforcing rib 23 is provided is not greater than 4mm, which can avoid uneven wall thickness of the end cover 2 and avoid large strength differences at various locations on the plate body 21.

[0055] In this embodiment, the wall thickness of the plate body 21 at the position where the second reinforcing rib 23 is provided is 3 mm, which can ensure the strength of the plate body 21 at the position where the second reinforcing rib 23 is provided to avoid breakage when subjected to impact. At the same time, it can avoid uneven wall thickness of the end cover 2 and avoid large strength differences at different locations on the plate body 21.

[0056] In some embodiments of the present invention, the thickness of the second reinforcing rib 23 is 0.5-1.5 mm. It is understandable that the thickness of the second reinforcing rib 23 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm. The thickness of the second reinforcing rib 23 is not less than 0.5 mm, which can ensure the reinforcing effect of the second reinforcing rib 23; the thickness of the second reinforcing rib 23 is not more than 1.5 mm, which can avoid uneven cooling of the position where the reinforcing rib is provided during injection molding of the end cover 2, avoid wrinkling of the appearance surface, and ensure uniform wall thickness of the end plate.

[0057] In this embodiment, the thickness of the second reinforcing rib 23 is 0.8 mm, which can ensure the reinforcing effect of the second reinforcing rib 23, and at the same time avoid uneven cooling of the position where the reinforcing rib is set during injection molding of the end cover 2, avoid wrinkling of the appearance surface, and ensure uniform wall thickness of the end plate.

[0058] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the second reinforcing rib 23 on the plate body 21 extends in the up-down direction, and the second reinforcing rib 23 on the mating plate 22 extends in the left-right direction, which can effectively increase the strength of the plate body 21 in the up-down direction, effectively increase the strength of the mating plate 22 in the left-right direction, increase the overall strength of the end plate, and avoid cracking of the end plate.

[0059] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, there are multiple second reinforcing ribs 23, and the multiple second reinforcing ribs 23 are arranged at intervals along the front-to-back direction, which can effectively increase the strength of the end plate in the front-to-back direction, increase the overall strength of the end plate, and avoid cracking of the end plate.
