In order to improve the comfort of the air conditioner, an air conditioner indoor unit capable of discharging air bidirectionally is available, and two air discharging modes of lower air discharging and side air discharging can be realized. The air conditioner indoor unit with one-way air outlet is provided with a filter screen at an air return opening, so that air flow entering the air conditioner indoor unit is filtered, and impurities are prevented from entering an air duct component. For the indoor unit of the air conditioner with bidirectional air outlet, because the air outlet is bidirectional, a filter screen component which can be switched in a reversing way is urgently needed to be matched with the indoor unit.

The filtering device has a filtering state for shielding the air port and an avoiding state for avoiding the air port; the air guide mechanism is arranged at the air inlet and is connected with the filtering device, and the air guide mechanism drives the filtering device to switch between a filtering state and an avoiding state; when the air inlet is used as an air return inlet, the air guide mechanism drives the filtering device to be in a filtering state, and when the air inlet is used as an air outlet, the air guide mechanism drives the filtering device to be in an avoiding state. The wind gap department is provided with the pivot, and wind guiding mechanism sets up in the pivot, and can revolute the pivot free rotation. The air guide mechanism is provided with a first edge and a second edge which are opposite, the first edge is arranged on the rotating shaft, and the second edge is connected with the filtering device.
