Abstract: A self-cleaning device of a filtering net is disposed in a wall-hanging type air conditioner and includes a filtering net with an upper filtering net and a front filtering net, which is disposed outside a heat exchanger and is used for absorbing dust in the air passing through the heat exchanger. A dust sweeping assembly with a detachable brush is disposed outside the filtering net, and is used for sweeping the dust adhered on the filtering net. A drive device with a drive motor and a transmission mechanism is used for driving the dust sweeping assembly to slide on the filtering net to sweep off the dust. A dust box is used for collecting the dust and is detachably disposed in the air conditioner to clear up the dust in the box. A dust exchanging device is disposed on the left or right side of the filtering net, and is used for transferring the dust swept out by the sweeping assembly into the dust box.
