The fresh air fan 31 can drive outdoor fresh air to flow from the fresh air inlet 124 to the auxiliary air duct 22, the main air duct 21 can be used for conveying air flow (including refrigerating air flow, heating air flow or normal-temperature air flow) to the indoor, and when the air outlet end of the main air duct 21 conveys air flow to the indoor, the fresh air in the auxiliary air duct 22 can be taken out, so that the outdoor fresh air can be introduced to the indoor, the indoor air is fresher, and the use comfort of the indoor air conditioner 100 is improved.

According to some embodiments of the present invention, referring to fig. 1-2, the air duct member 2 cooperates with the housing 1 to define a main air duct 21 and an auxiliary air duct 22 disposed at an interval, an air outlet end of the auxiliary air duct 22 is disposed adjacent to an air outlet end of the main air duct 21, the main air duct 21 is respectively communicated with the air outlet 1231 and the first indoor air inlet 1211, the auxiliary air duct 22 is communicated with the air outlet 1231, and the main fan 23 is disposed in the main air duct 21; the indoor heat exchanger 4 is disposed in the cabinet 1 between the first indoor air inlet 1211 and the main fan 23.

It can be understood that the main fan 23 is disposed in the main air duct 21 and can drive the air flow to flow from the first indoor air inlet 1211 to the air outlet 1231, and then flow into the room, and in the process that the air flow flows from the first indoor air inlet 1211 to the air outlet 1231, the air flow passes through the indoor heat exchanger 4 and exchanges heat with the indoor heat exchanger 4, so that the temperature of the air flow decreases or increases, and further the air flow flowing into the room can be cooled or heated. Because the air outlet end of the auxiliary air duct 22 is adjacent to the air outlet end of the main air duct 21, when the air outlet end of the main air duct 21 is exhausted, the air flow in the auxiliary air duct 22 is brought out of the auxiliary air duct 22, so that the air output of the air outlet 1231 can be increased, and the cooling or heating effect of the indoor unit 100 of the air conditioner is better.

In addition, the main blower 23 may be operated alone, and at this time, the cooling air or the heating air flows into the room through the main duct 21 and the auxiliary duct 22; the fresh air fan 31 can also work independently, and at the moment, outdoor fresh air flows indoors through the auxiliary air duct 22; the main fan 23 and the fresh air fan 31 can also work simultaneously, at this time, the cooling air or the heating air flows indoors through the main air duct 21, the outdoor fresh air flows indoors through the auxiliary air duct 22, certainly, when the main fan 23 and the fresh air fan 31 work simultaneously, the compressor for controlling the flow of the refrigerant in the indoor heat exchanger 4 can not work, and at this time, the main fan 23 drives the normal-temperature air flow to blow out from the main air duct 21 and simultaneously drives the outdoor fresh air of the auxiliary air duct 22 to blow out.
