外部へ排出せられる。When both the centrifugal exhaust pipe and the cylinder of the present invention installed above the source of smoke emission are driven, a gas suction force is generated at the center of the centrifugal exhaust pipe, and The drive causes a vortex inside the cylinder and in the lower part of the cylinder. In the lower part of the cylinder, the centripetal force toward the center of the vortex flow and the centrifugal force balance. Therefore, the flow of the surrounding air does not enter into the vortex flow from the side of the vortex flow in the equilibrium state in which the centripetal force and the centrifugal force are balanced, and therefore enters from the lower surface of the vortex flow. Further, in the same manner, the air coming in from the lower surface creates a vortex at that position,
In this case as well, the pressure difference between the inside and outside of the vortex and the flow of the swirling air flow maintain a balance, so that the surrounding air cannot enter from the side, and therefore the vortex further enters from below. Then, by repeating such an action, the vortex is stretched downward and an artificial tornado is generated by the mechanical chimney effect of forming a vortex tube. In this way, the vortex flow of the artificial tornado extending to the ground stalls and the centrifugal force decreases,
The air around the ground is drawn to the center of the vortex by the centripetal force, passes through the core of the artificial tornado, and is discharged to the outside from the above-mentioned centrifugal exhaust stack.

めて効率よく行われる。Next, the function and effect of the above embodiment will be described. First, when the motor 13 is driven, the centrifugal exhaust cylinder 11 and the cylinder 12 rotate around the motor shaft 13a.
In that case, the air inside the centrifugal exhaust stack 11 is
1 is discharged in the circumferential direction, and the exhaust hole 14 is inserted through the gap 16.
Further, the air in the cylinder 12 is vertically rectified by the rectifying fins 18 from the opening portion opened at the central portion of the bottom plate 11a of the centrifugal exhaust cylinder 11 in the vertical direction. Suction into the cylinder 11. At this time, the air inside the cylinder 12 is rotated by the rotation of the plate-shaped blades 19, 19 ... Provided inside the cylinder 12, and swirls a and b are formed in the air inside the cylinder 12 and the air below the cylinder 12. Excuse me. Further, in the lower part of the cylinder 12, the centripetal force toward the center of the vortex b and the centrifugal force are balanced, so that the peripheral air 2 of the vortex b is
1 cannot enter the vortex flow b from the side of the vortex flow b, and will enter the vortex flow b exclusively from below the vortex flow b. Further, air 21 coming in from the lower end surface in the same manner.
Forms a vortex c at that portion, and here again, the pressure difference between the inside and outside of the vortex c and the flow of the swirling air flow maintain balance,
Therefore, the peripheral air 21a of the vortex c cannot enter the vortex c from the side surface of the vortex c, but enters from the lower surface of the vortex c. Then, by repeating such actions, the vortex is stretched downward and the artificial tornado 22 is generated by the mechanical chimney effect of forming a vortex tube. Thus, the vortex flow of the artificial tornado 22 extending to the vicinity of the ground M stalls and the centrifugal force becomes small, and the air 21b near the ground M is drawn into the center of the vortex by the centripetal force, and the artificial tornado 2
The cylinder 1 is sucked upward through the second core 22a.
2, enters the centrifugal exhaust cylinder 11 while forming the vortex flow a here, and is discharged to the outside from the exhaust hole 14 of the hood 15. Thus, the smoke exhaust generated in the vicinity of the range 20 in FIG. 1 is drawn into the artificial tornado 22 and released to the outside without being diffused to the surroundings, so that the ventilation of the room is performed very efficiently.

In the figure, what corresponds to the cylinder 12 of the embodiment shown in FIG. 2 is an outer cylinder 15 a that is connected to the lower part of the hood 15. Therefore, the outer cylinder 15a does not rotate, and the blades 19a, 19a ... Inside the outer cylinder 15a rotate about the motor shaft 13a to form the vortex flow a, and the embodiment shown in FIG. It has the same effect.

Since the equipment space is small, and because it is the ventilation by the chimney effect by the artificial tornado as described above, it is possible to obtain high ventilation efficiency with extremely small energy compared to the conventional ventilation device, and try to scatter further. This is an invention that has a very significant effect such that oil and the like can be converged and processed.
