The table body 4 forms a box having an open top. The air outlet 2 is located at the bottom of the box, and air outlets 6 are provided on both sides. The table 1 with the air control function may be of a type in which the tornado-type suction device 5 is directly detachably provided on the table body 4. In this embodiment, a top plate 10 is provided on the table main body 4, and a tornado-type suction device 5 is detachably provided thereon.

That is, the top plate 10 is provided with an air suction port 11 having a predetermined opening dimension.
1 is located on the suction side of the blower 3, an edge plate 12 is provided therearound, and a tornado-type suction device 5 is detachably provided on the air suction port 11 so as to fit on the edge plate 12.

The top plate 10 is made of a flat plate having a certain thickness, but is not limited to this and may have another shape. The material is not limited to wood, plastic, metal and the like. In addition, the movable ashtray 13 is placed on the top 10, but the ashtray 13 may be fixed to the top of the top 10.

The tornado-type suction device 5 has a cutout 22 in a side wall 21 of a cylindrical body 20 and a suction hole 23 in at least one of both longitudinal ends of the cylindrical body 20. Connected to the suction side.
In this embodiment, the suction holes 23 are formed in the side plates 24 at both ends in the longitudinal direction of the cylindrical body 20.
There are two 0s. These cylindrical bodies 20 are arranged such that the cutouts 22 are in the opposite direction and the side walls 21 are slightly separated from each other.
It is fixed to. Further, the cover 2 is placed above the cylindrical body 20.
5, a gap between the cylindrical body 20 and the cover 25 is defined as a suction opening 26, and the suction opening 26 is connected to the suction side of the blower 3 through the air suction port 11. A cover 27 that covers the two suction holes 23 at both ends of the cylindrical body 20 is fixed to the side plate 24, and the two suction holes 23 are connected to the suction side of the blower 3 through the air suction port 11 at the cover 27. ing.

In the embodiment, the cross-sectional shape of the cylindrical body 20 is a perfect circle, but it may be a spiral shape. In this case, a stable tornado can be generated without the suction opening 26. It becomes possible. Further, the tornado type suction device 5 is manufactured so as to be fitted to the outer dimensions of the air suction port 11 so that it can be attached and detached.

An air purifying device 30 is provided in the table body 4 between the air outlet 2 and the tornado suction device 5. The air purifier 30 is for purifying contaminated air that has entered the table main body 4 through the air suction port 11, and its type, structure, and the like are not particularly limited.

In this embodiment, the air cleaning device 30
Is a pre-filter 31 for removing relatively large particles in contaminated air, and an electrostatic precipitator 3 for removing fine particles.
2, and a deodorizing filter 3 for removing gaseous odor components
3, a pre-filter 31, an electric precipitator 32,
Deodorizing filters 33 are stored in this order. Therefore, the air purifying device 30 has a higher purifying ability and a longer life than a device that purifies at a time with an air purifying filter.

Further, the electric precipitator 32 returns after a short-circuit between the plates, for example, after turning off the power supply for a predetermined time, for example, 10 seconds, or after reducing the discharge voltage for 10 seconds, and then returns. A certain number of times within a certain time,
For example, it has a built-in program that issues an alarm when it reaches 10 times an hour. For this reason, since the suction hole 23 is located at a high position at both ends of the cylindrical body 20 and the suction opening 26 is also at the top, it is difficult for cigarette ash and the like to enter the table body 4 through the air suction port 11. Even if foreign matter having a large particle size such as tobacco ash enters the electrostatic precipitator 32 and the electrodes are short-circuited, for example, the power is turned off or the discharge voltage is reduced for 10 seconds. Or a crackling sound that is inaudible to humans,
In the meantime, a large foreign substance passes between the electrode plates, and does not crack even if the power is turned on after 10 seconds. Furthermore, if this short circuit reaches, for example, 10 times or more in one hour, an alarm is issued as an abnormality has occurred and an appropriate action can be taken.

The deodorizing filter 33 extends over the entire surface of the air discharge port 2 and the air release port 6 provided on the bottom and both side surfaces of the table body 4. Accordingly, the electric dust collector 32 removes the odor in the air except for the suspended matter to make clean air, and the clean air is discharged from the air outlet 2 toward the floor, so that the operation sound of the blower 3 is indirectly generated. Since part of the clean air passes through the two air outlets 6, the amount of clean air discharged from the air outlets 2 is relatively reduced, and the wind speed hitting the feet is reduced, so that the feet do not feel cold.

The blower 3 is provided with impellers 35, 35 on both shafts of a motor 34. The blower 3 removes contaminated air existing above the top plate 10, especially at its peripheral edge and in the vicinity thereof. The air is sucked into the table body 4 from the air suction port 11 together with the air, and passes through the air cleaning device 30 to discharge the clean air from the air discharge port 2 at the lower portion of the table body 4. Therefore, as long as the blower 3 satisfies a predetermined pressure and air volume, its type, structure and the like are not limited.

Next, power is turned on to the blower 3 and when the blower 3 is in a steady operation, air is sucked from the suction hole 23 and the suction opening 26, so that air around the tornado-type suction device 5 is sucked. The air enters into the cylindrical body 20 through the cutout 22 and is guided by the arc-shaped side wall 21 to generate the swirling airflow S. In the swirling airflow S, suction holes 2
A negative pressure region is formed by suction of the air from the airflow 3, and a centripetal force is applied by the swirling airflow S. At the same time, a centrifugal force is also applied by the swirling airflow S. Becomes a vortex, and a tornado t toward the suction hole 23 converging on the central axis of the swirling airflow S is generated in the cylindrical body 20. In addition, a device for visualizing the tornado t generated in the cylindrical body 20, for example, by making the inner surface of the cylindrical body 20 black and making the tornado t easily visible, the smoker exhales smoke toward the cylindrical body. Can be motivated.

In this state, when a cigarette is smoked near the ashtray 13 in the table 1 with the air control function, the smoke is immediately generated in the tornado-type suction device 5 together with the surrounding air in the tornado t.
Is sucked into the table body 4 through the suction hole 23, the cover 25, and the air suction port 11 due to the vortex convergence, and at the same time, the smoke above the suction opening 26 in the upper part of the tornado suction device 5 is formed by the cover 27. Passage, air suction port 11
Is sucked into the table main body 4 via. In the air containing smoke, relatively large particles contained in the air are removed by the pre-filter 31, fine particles are captured by the electrostatic precipitator 32, and further, odor components such as gas are removed by the deodorizing filter 33, It becomes clean air. At this time, the clean air discharged to the outside from the air discharge port 2 is dispersed by the two air release ports 6, the wind speed from the air discharge port 2 is reduced, the feet do not feel cold, and the operation sound of the blower 9 is also dispersed. descend.

At this time, if foreign matter such as tobacco ash enters the electric precipitator 32 and short-circuits between the electrodes, the power is turned off or the discharge voltage drops, and the crackling sound stops immediately. It recovers or discharge voltage returns to normal, and captures fine particles. If the number of shorts is large, a warning is issued, so it is sufficient to take appropriate measures.
