The upper air duct is in communication with the air inlet 103, the lower air duct is in communication with the air outlet 104, and the upper air duct and the lower air duct are in communication through the air passing opening 105. The indoor heat exchanger 300 is located in the upper air duct. The air entering from the air inlet 103 exchanges heat with the indoor heat exchanger 300, and then enters the lower air duct through the air passing opening 105 and finally flows out of the air outlet 104.

[0059] Further, the indoor heat exchanger 300 is installed on the concave surface of the second arc-shaped plate.

[0060] In some embodiments, the air conditioner indoor unit further comprises a fresh air assembly 500 and a smoke exhaust assembly 600; the fresh air assembly 500 is installed in the fresh air duct 101, for making air flow from the air inlet 103 into the fresh air duct 101, and flow out from the air outlet 104; the smoke exhaust assembly 600 is installed in the smoke exhaust duct 102, for making oil fume flow from the oil fume inlet into the smoke exhaust duct 102, and flow out from the oil fume outlet 106.

By setting the smoke exhaust assembly 600 in the smoke exhaust duct 102, the oil fume flow can be powered, ensuring that the air can smoothly flow from the oil fume inlet into the smoke exhaust duct 102, and smoothly flow out from the smoke exhaust duct.

[0061] Further, the fresh air assembly 500 comprises a fresh air cross-flow fan; the smoke exhaust assembly 600 comprises a smoke exhaust cross-flow fan 610 and a smoke exhaust axial flow fan 620; the smoke exhaust cross-flow fan 610 is installed in the smoke exhaust duct 102; the smoke exhaust axial flow fan 620 is installed in the oil fume inlet. By setting the smoke exhaust cross-flow fan 610 and the smoke exhaust axial flow fan 620 on the oil fume flow path, the air exchange efficiency can be increased.

[0062] Specifically, the fresh air cross-flow fan is installed in the lower air duct, in other words, the fresh air cross-flow fan is installed on the side of the indoor heat exchanger 300 far away from the air inlet 103.

[0063] In some embodiments, the air conditioner indoor unit comprises a smoke exhaust mode and a cooling / heating mode. In the smoke exhaust mode, the air conditioner indoor unit can exhaust the kitchen indoor oil fume into the outdoor atmosphere. In the cooling / heating mode, the air conditioner indoor unit can blow cold air or hot air into the kitchen.

[0064] In the smoke exhaust mode, the smoke exhaust assembly 600 has multiple operating gears. Specifically, in the smoke exhaust mode, the smoke exhaust assembly 600 has three operating gears, wherein the first gear is that the rotation speed of the smoke exhaust cross-flow fan 610 is a first cross-flow rotation speed, and the rotation speed of the smoke exhaust axial flow fan 620 is a first axial flow rotation speed; the second gear is that the rotation speed of the smoke exhaust cross-flow fan 610 is a second cross-flow rotation speed, and the rotation speed of the smoke exhaust axial flow fan 620 is a second axial flow rotation speed; the third gear is that the rotation speed of the smoke exhaust cross-flow fan 610 is a third cross-flow rotation speed, and the rotation speed of the smoke exhaust axial flow fan 620 is a third axial flow rotation speed. The second cross-flow rotation speed is greater than the first cross-flow rotation speed and less than the third cross-flow rotation speed. The second axial flow rotation speed is greater than the first axial flow rotation speed and less than the third axial flow rotation speed.

[0065] Specifically, in the second and third gears, the fresh air cross-flow fan can also be started to ensure the indoor and outdoor pressure difference, ensure normal air circulation, and avoid unnecessary noise.

[0066] In the refrigeration and heating mode, the new air through-flow fan is started to send air into the room. In order to ensure the pressure difference between the indoor and outdoor, and ensure the normal circulation of air, the exhaust smoke axial flow fan 620 can also be started in the refrigeration and heating mode.
