Title: DUST COLLECTING DEVICE
Abstract:
In the present invention, a vortex flow generating unit 30 causes dust-containing air which has flowed in from an inflow port to swirl, thereby centrifuging the dust. A dust collection unit 80 collects the dust which has been centrifuged by the vortex flow generating unit 30. A connecting section 34 connects a discharge port 42 of the vortex flow generating unit 30 and an opening 86 of the dust collection unit 80. In the dust collection unit 80, a second swirl acceleration unit 88 causes air which contains dust and has flowed in from the opening 86 through the connecting section 34 to swirl, and a dust collection chamber 84 stores the dust which has been centrifuged by the second swirl acceleration unit 88. A dust collecting device 20 is provided with a return route 82 for returning to the vortex flow generating unit 30 the air which has flowed into the dust collection unit 80.
