According to the air-conditioning indoor unit 100 of the embodiment of the invention, by arranging the plurality of indicator light groups 20 and the air outlets which are arranged in a one-to-one correspondence manner, each indicator light group 20 can display the controlled state of the air outlet corresponding to the indicator light group, so that a user can conveniently recognize the controlled state. Therefore, an indoor user can remotely control the air supply state of each air outlet according to the requirement, the operation is more convenient, and the practical performance of the indoor unit 100 of the air conditioner can be improved.

As shown in fig. 4, 7-8, according to some embodiments of the present invention, the inner surface of the display portion 210 is provided with an inwardly extending light converging portion 210B, and the light converging portion 210B extends between the LED lamp 240 and the light shielding portion 220, so that the display effect of the indicator light set 20 can be improved. For example, as shown in fig. 4, the light converging portion 210B is formed in a boss shape extending in the outside-in direction, and the light transmitting hole 210A penetrates the light converging portion 210B in the outside-in direction. As shown in fig. 7, when the indicator light assembly 20 is assembled, the light-converging portion 210B is inserted into the corresponding through hole 220A, and the LED lamp 240 is positioned in the light-transmitting hole 210A. Since the light shielding portion 220 is made of opaque material, the inner peripheral wall of the light collecting portion 210B can refract the light emitted from the LED lamp 240, so that the light emitted from the LED lamp 240 can be completely transmitted, thereby achieving a better display effect.

As shown in fig. 7, according to some embodiments of the present invention, the display part 210 and the circuit board 230 are snap-fitted, whereby the fitting structure of the display part 210 and the circuit board 230 may be made simpler.
