External air enters the dust removing space from the air outlet 244, and due to the arrangement of the vortex plate 30, dust is impacted on the surface of the vortex plate 30 and separated from the air due to the continuous change of the air flow direction when the air flows in the vortex plate 30, and the air dust removing is realized through the arrangement of the vortex plate 30. When the air in the box 11 flows into the dust removing space through the treatment box 24 and the sleeve plate 29, the hot air flows in the vortex plate 30 and continuously impacts the surface of the vortex plate 30, the dust on the vortex plate 30 is impacted and taken out of the dust removing space, and the self-cleaning of the dust removing structure is realized by the air external circulation mode.
When the air inside the casing 11 circulates, the air does not pass through the shroud 29 and the scroll 30 when the air circulates because the air inside the casing 11 does not contain dust.
