Abstract:
1. A self-cleaning device of a filtering net of an air conditioner, which is to be installed on a filtering net frame in an air inlet of a dust spiral case of a packaged air conditioner and is to be disposed outside of the filtering net, wherein, the self-cleaning device of the filtering net comprises a sweeping assembly with a brush, a drive motor fixed on the sweeping assembly, a transmission mechanism connected to the drive motor, a rack group installed on the left and right sides of the filtering net, a dust collecting box to be under the filtering net for collecting dust, and a dust exchanging device disposed between the dust collecting box and the filtering net, the drive motor connecting with the transmission mechanism drives the sweeping assembly to slide up and down the filtering net along the rack group, so that dust is cleaned by the brush and is then is put into the dust collecting box through the dust exchanging device, wherein the sweeping assembly includes a sweeping frame, a brush and a sweeping assembly dustproof cover, the sweeping frame is transversely installed on the lateral part of the filtering net, the brush is fixed on the side of the sweeping frame adjacent the filtering net, the sweeping frame movable via sliding shafts set on the left and the right sides of the filtering net and slides up and down to clean the dust, the sliding shafts being vertically fixed on the filtering frame, the drive motor and the transmission mechanism are fixed on the sweeping frame, the transmission mechanism includes a drive shaft, transmission gears mounted on the two ends of the drive shaft, and a driven gear fixed between the two ends of the drive shaft, the transmission gears are respectively joggled with the rack group on the left and right sides of the filtering net, the drive motor drives the driven shaft to rotate by the joggle of the drive gear with the driven gear, thus making the sweeping assembly clean dust by sliding up and down on the rack group along the sliding shafts, and the sweeping assembly dustproof cover is fastened on a lateral side of the sweeping frame to prevent dust on the sweeping assembly, a dust collecting box frame is set to be under the filtering net, the dust collecting box frame is in a plane with the filtering net and has an upper slot and lower slot, the dust collecting box frame is “ the dust exchanging device is a rectangular frame, a wool roll for absorbing dust is transversely pin-jointed in the rectangular frame, the wool roll is of an oval column structure, and the wool roll has a reset mechanism which is made of a spring or an extensive spring, and a block is disposed at each of the right and left sides of the wool roll, and a baffle is pin-jointed on the rectangular frame in the direction of wool roll, the baffle also has a reset mechanism which realizes a second dust exchange with a felt located on a side of the reset mechanism adjacent to the wool roll, and a soft baffle is set under the wool roll along a tangent of the wool roll.
