Abstract

PROBLEM TO BE SOLVED: To suck smoke from a cigarette and lamp black generated at cooking, by rotating a wind tunnel provided with an opening at its peripheral wall, taking in a volute flow generated in the wind tunnel by an air blower, and exhausting the flow to the outside of a device. SOLUTION: This suction device comprises a main body 8 provided with an air blower 1, and a wind tunnel 4 rotatably attached by a rotation member 6 mounted to the main body 8 and provided with an opening 5 at its peripheral surface. The wind tunnel 4 is connected to a suction pipe 2 connected to a suction port of the air blower 1. As a rotation means 6 rotates, the wind tunnel 4 rotates and a rotation force is imparted to an air flow flowing in the wind tunnel 4. When the air blower 1 rotates in this state, the air blower 1 takes in an air flowing in the wind tunnel 4 from the suction pipe 2 and exhausts it through an exhaust port 7 to the outside. At this time, the wind tunnel 4 has the opening 5 at its peripheral wall, the air flowing into the wind tunnel 4 becomes a volute flow, whereby smoke from a cigarette generated at a far place, lamp black generated at cooking, dust, or odor can be efficiently sucked.
