The air duct structure 20 is arranged between the wall hanging plate 11 and the air outlet panel 12; the air guiding member 30 is movably disposed in the air duct structure 20, so that the air duct structure 20 can selectively communicate with the at least one air outlet by adjusting the air guiding position of the air guiding member 30.

By adopting the air-conditioning indoor unit provided by this embodiment, the air outlet panel 12 is provided with the plurality of air outlets, and the air duct structure 20 can be conveniently and selectively communicated with at least one air outlet by adjusting the flow guiding position of the flow guiding member 30. Specifically, when the air conditioning indoor unit is in the cold air mode, the air duct structure 20 may be communicated with an air outlet at a higher position to prevent cold air from directly blowing people; when the indoor unit of the air conditioner is in a hot air mode, the air duct structure 20 can be communicated with an air outlet at a lower height position, so that the situation that hot air cannot sink is avoided; when need all be air-out from top to bottom, can be through the air-out simultaneously of a plurality of air outlets. Therefore, the air-conditioning indoor unit provided by the embodiment can solve the technical problem that the comfort of the air-conditioning indoor unit in the prior art is poor.

Specifically, the air outlet panel 12 in this embodiment is provided with a first air outlet 121 and a second air outlet 122, the first air outlet 121 is located above the second air outlet 122, and the air duct structure 20 is selectively communicated with the first air outlet 121, the second air outlet 122, or both the first air outlet 121 and the second air outlet 122. By adopting the structure, when the air duct structure is in the cold air mode, the air duct structure 20 can be communicated with the first air outlet 121, so that cold air is prevented from directly blowing people; when in the hot air mode, the air duct structure 20 may be communicated with the second air outlet 122 to prevent the hot air from sinking; when the air is exhausted from the upper portion and the lower portion, the air duct structure 20 is communicated with the first air outlet 121 and the second air outlet 122, so that the first air outlet 121 and the second air outlet 122 are exhausted at the same time.

Correspondingly, the air guide 30 may also extend along the extension direction of the indoor unit casing 10, or the air guide 30 may extend along the horizontal direction or a direction which forms an angle of less than 15 ° with the horizontal direction.

In this embodiment, the air duct structure 20 has a first sub air duct 21, a second sub air duct 22 and a main air duct 23, the first sub air duct 21 and the second sub air duct 22 are both communicated with the main air duct 23, one end of the first sub air duct 21 far away from the main air duct 23 is communicated with the first air outlet 121, and one end of the first sub air duct 21 close to the main air duct 23 forms a first communicating opening 211. One end of the second sub air duct 22 far away from the main air duct 23 is communicated with the second air outlet 122, and one end of the second sub air duct 22 close to the main air duct 23 forms a second communication port 221. The baffle 30 is movably disposed between the first communication port 211 and the second communication port 221. With such a structure, by adjusting the position of the air guide member 30, the position of the air guide member 30 relative to the first communication port 211 and the second communication port 221 is changed, so that the air in the main air duct 23 is guided into the first sub air duct 21, the second sub air duct 22, or the first sub air duct 21 and the second sub air duct 22 through the air guide member 30.

Specifically, the flow guide member 30 is rotatably disposed between the first air outlet 121 and the second air outlet 122, and the flow guide member 30 has a first flow guide position, a second flow guide position and a third flow guide position.
