Further, the second ribs 128 have a lower projection height than the first ribs 127. That is, in the longitudinal direction of the middle frame 110, the distance between the second rib 128 and the middle frame 110 is greater than the distance between the first rib 127 and the middle frame 110, so that the influence of the second rib 128 on the attachment and detachment of the loose leaf 132 can be reduced. Optionally, in this embodiment, the extending direction of the second rib 128 is perpendicular to the first rib 127, that is, the grid formed by the second rib 128 and the first rib 127 is square.

According to the air conditioner indoor unit 100 and the air conditioner provided by the embodiment of the utility model, the end cover 120 is provided with the limiting protrusion 126 opposite to the elastic buckle 113, so that under the condition that the panel 130 is in an open state, the reliability of the hinge 132 is improved through the mutual interference of the elastic buckle 113 and the limiting protrusion 126 on the hinge 132, and the problem that the abutting protrusion 133 of the hinge 132 is separated from the elastic buckle 113 to close the panel 130 due to the deformation of the hinge 132 is avoided. Meanwhile, by further arranging the structure of the limiting protrusion 126, the influence on the disassembly and assembly process of the panel 130 after the limiting protrusion 126 is additionally arranged is reduced, the disassembly and assembly process of the panel 130 is ensured to be smooth, and the sliding friction force generated on the panel 130 in the opening and closing process of the panel 130 is reduced.
