By operating the blower b to blow air from the outlet c to form an air curtain g, the smoking space i is created by combining the floor h, the ceiling e, the screen a and the like.
The inside air is exhausted to the outside by the suction fan f of the ceiling e to make the inside of the smoking space i a negative pressure so that the contaminated air does not flow out to other spaces in the room.

There is also a smoking unit as shown in FIG. 15 (see Japanese Utility Model Laid-Open No. 7-35927). This smoking unit has an outlet c around the ceiling j and the ceiling j
Has a suction port d at the center thereof, and creates a smoking space i by combining with the floor h and the ceiling j by the air curtain g from the air outlet c. The air in the smoking space i is supplied to the suction port d of the ceiling j. To make the inside of the smoking space i temporarily negative pressure, so that smoke and odors do not flow out to other spaces in the room,
The air is blown out again from the outlet c as clean air by an air purifier in the ceiling j and circulated.

A smoking counter k as shown in FIG. 16 is arranged at a corner of a room, has an exhaust port m on a side surface of a counter body 1 and a suction port n on an upper surface, and is provided above the suction port n. A shielding plate o is provided supported by a support p, and an air purifier is provided in a smoking counter k between a suction port n and an exhaust port m. When a person smokes in the vicinity of the smoking counter k, the smoke is shielded with the surrounding air.

In FIGS. 1, 2, 6 to 8, when the blower 9 of the airflow control type smoke separator 1 is operated, air is blown out from the outlet 6 to form the air curtain 5 and border it. The room A is divided into a smoking space 11 and a non-smoking space 12. Cigarette smoke emitted from the smoker in the smoking space 11 is immediately captured without affecting other smokers, sucked into the suction port 7 together with air, and purified by the air purifier 10 to remove air. Once stored in the reservoir 3b, the turbulent state is mitigated. After that, a deodorizing filter 2 that also serves as a current plate
7, the clean air is deodorized and rectified, and the clean air is
A part is discharged from the exhaust port 8 to the non-smoking space 12, and the remaining part is blown out from the outlets 6 provided on the upper and side portions to form the air curtain 5 by clean air. If there is a lead plate 34 in the upper outlet 6, it is guided, and if it is stable and has a curved tip, the curved air curtain 5 attracts the smoke which is going to break it to the smoking space 11 side, and the non-smoking space. Don't put it in 12. Also, when the lead plate 39 is provided at the side outlet 6, the same operation as described above is performed, and even if the branch passage 37 is selected by operating the switching plate 38 of the wind direction switching device 35, the same operation as described above is performed. Works.

On the other hand, the smoke that has not been captured is the smoking space 1

As described above in detail, the airflow control type smoke separator according to the present invention has the following effects. Claim 1
In the invention of the present invention, the room is divided by an air curtain and a panel, and one of the spaces is designated as a smoking space, and the smoke around the machine main body in the smoking space is immediately sucked from a suction port, and is partially purified air by an air purifier. Is exhausted to the outside of the smoking space through the exhaust port, and the amount of this clean air exhausted from the exhaust port is larger than the amount of external entrained air from outside the smoking space. Therefore, the inside of the smoking space is maintained at a negative pressure. Then, the remaining portion of the clean air is blown out from the outlet to form an air curtain. On the other hand, smoke that was not immediately sucked from the suction port,
Since the inside of the smoking space is partitioned by an air curtain and a panel and is in a negative pressure state, it is eventually sucked in from the suction port, turned into clean air by the air purifier, and discharged out of the smoking space from the exhaust port. Therefore, it is possible to easily create a smoking space in one corner of the room with the air curtain by the clean air, without causing the smoke to flow out of the smoking space, and circulating the clean air out of the indoor smoking space, This has the effect that it does not affect the indoor air-conditioning equipment, while at the same time inhaling the smoke immediately in the smoking space so that other smokers do not smoke.

According to the second aspect of the present invention, since the panel can be removed from the box, it is easy to pack when transporting, and it is easy to load, unload and carry in.

According to the third aspect of the present invention, the panel removed from the box can be further divided, so that the panel can be easily transported.

According to a fourth aspect of the present invention, since the inside and outside of the smoking space are partitioned by the air curtain and the panel formed from the air outlets at the top and side of the panel, the portion not partitioned by the air curtain is reduced, and the smoking space is reduced accordingly. The amount of external entrained air from the outside is reduced, the negative pressure state in the smoking space is stabilized, and smoke does not leak out of the smoking space. Therefore, the above effect can be further enhanced.

According to the fifth aspect of the present invention, since the clean air is temporarily stored in the air reservoir, the turbulence of the air flow is reduced, and the clean air can be distributed to the exhaust port and the outlet at a predetermined ratio. Therefore, it is possible to blow out the clean air from the outlet of the panel to form an air curtain with the clean air having a uniform flow velocity.

According to the sixth aspect of the present invention, since the clean air whose air flow has been alleviated by the air reservoir is further passed through the straightening plate, the clean air can be further distributed to the exhaust port and the blow port at a predetermined ratio. . Therefore, it is possible to further obtain an air curtain with clean air having the above-mentioned flow velocity uniformized.

According to the seventh aspect of the present invention, it is possible to perform both rectification and deodorization by passing undeodorized clean air through the deodorizing filter. Therefore, a current plate is not required,
As a result, the structure is simplified, and both initial and running costs can be reduced.

According to the eighth aspect of the present invention, the negative ion generator can be attached and detached as needed, and the effect of the negative ions can be appropriately enjoyed. Therefore, the space of the air reservoir can be effectively utilized, and the differentiation of products becomes remarkable.

According to the ninth aspect of the present invention, it is possible to prevent a smoker from closing the panel outlet with his / her hand or elbow, and to stabilize the air curtain formed from the panel outlet by the lead plate. Since the inside and outside of the smoking space are partitioned by the board itself and the stable air curtain and panel, the partition inside and outside of the smoking space is assured accordingly, the amount of external air from outside the smoking space is reduced, and the negative pressure state in the smoking space is stable In addition, smoke is less likely to leak out of the smoking space. Therefore, it is possible to reliably prevent the smoke of the tobacco from entering the above-mentioned non-smoking space, and the effect described above can be further enhanced.

According to the tenth aspect of the present invention, the partitioning property inside and outside the smoking space is ensured, and the feeling of closure in the smoking space is reduced. Thus, the conflicting purpose of achieving a sense of closure while achieving partitioning is achieved.

According to the eleventh aspect of the present invention, the shielding plate reduces the mutual interference with the air curtain from the air outlet, and widens the range of direct suction in the horizontal direction of the suction port. Therefore, while having a simple structure, smokers rarely smoke each other in the smoking space.

According to a twelfth aspect of the present invention, it is possible to maximize the range of the direct suction of the suction port within a range in which the tornado generated in the cylinder does not interfere with the air curtain from the air outlet. . Therefore, the smoker can further fulfill his wish that he does not want to smoke the smoke of others.

According to the thirteenth aspect of the present invention, it is possible to easily move to any place in the room to create a smoking space, and smokers rarely smoke other people. Thus, both non-smokers and smokers have little chance of smoking the tobacco of others.

According to the fourteenth aspect, the direction of the air curtain can be changed according to the installation state in the room, and a more appropriate smoking space can be created. Therefore, a relatively wide range of smoking space can be created in the room with almost no restriction on its shape, and the smoking space has a structure in which the smoke of cigarettes is further prevented from leaking.
