BACKGROUND OF THE INVENTION
The present invention surrounds a part of a room with an air curtain without making a partition or installing an obstacle in a room such as a building, an aircraft, or a vehicle. The present invention relates to a smoking space creation system that prevents smoke and odors from being emitted directly into the room outside the space.
[0002]
[Prior art]
Conventionally, as a method of partitioning a part of the room and making the place into a smoking booth or a coffee room, a vertical stand is often used. The purpose of this erection is to partition the air, so that air flows in and out of the upper space, so that polluted air inside and outside (cigarette smoke, exhaust gas, airborne dust, harmful gas) and bad odors flow in and out. Occurs.
[0003]
In order to prevent this adverse effect, there is erected with a built-in air curtain generating device such as shown in FIG. 15. This vertical stand a has a blower b built in, an air outlet c that forms an air curtain at the top, and a suction port d on the side surface. A part of the interior of the room is enclosed by the vertical stand a with the suction port d inside. Further, a suction fan f is installed on the ceiling e above the installation place of the stand a. The blower b is operated to blow air from the outlet c to form an air curtain g to form a partial space i in combination with the floor h, the ceiling e, the standing a, etc., and the air in the partial space i is sent to the ceiling e The air is exhausted to the outside by a suction fan f so as to create a negative pressure in a part of the space i so that polluted air and bad odor do not flow out to other spaces in the room.
[0004]
Further, there is a smoking unit as shown in FIG. 16 (see Japanese Utility Model Laid-Open No. 7-35927). This smoking unit has an outlet c around the ceiling e, a suction port d in the center of the ceiling j, and a partial space i coupled with the floor h and the ceiling j by an air curtain g from the outlet c. The air in the partial space i is sucked and discharged through the suction port d of the ceiling j to temporarily reduce the pressure in the partial space i, so that smoke and odors flow out to other spaces in the room. In other words, the air purifier in the ceiling portion j is blown out from the air outlet c and circulated again as decontaminated air.
[0005]
[Problems to be solved by the invention]
However, in the example shown in FIG. 15 described above, a part of the room is partitioned by a, and the place can be immediately used as a smoking booth or a coffee room, but it is easy for people to come and go. Can't be made and the prospects are not good.
[0006]
In addition, the smoking unit in FIG. 16 requires a column k that supports the ceiling j, and even if the smoking unit is of a type that is suspended from the ceiling e, the partial space i can be temporarily brought into a negative pressure state. Even if it can, the air sucked from the suction port d in the central part is used again as the air curtain g from the blowout port c. It is difficult to make a good smoking space because smoke and odors leak to other spaces in the room.
[0007]
Therefore, the present invention has been made in view of the above circumstances, and does not make a partition or install an obstacle in the room, and maintains a stable negative pressure in a part of the room, thereby generating smoke. It is an object of the present invention to provide a smoking space creation system that can be discharged outside the room without flowing out from a part of the space, or cleaned and circulated back into the room.

[0026]
This air purifier 30a is integrated with an air suction part 32, an air discharge part 33 and an air purifying part 34 (all not shown) in the purifier main body 31a in substantially the same manner as the air purifier 30 which is a smoke separator. Since it is configured, its description is omitted. The air purifier 30a, since not intended to clean immediately aspirated cigarette smoke, the smoke of others even the smokers Given that those unpleasant, desk 11 in Fig. 13 and 14 Instead, there is no problem even if the air cleaner 30 of FIGS. 9 to 11 as a smoke separator is installed and the smoke is immediately suction-cleaned. Rather, since the amount of air discharged to the outside of the partial space 3 increases, the negative pressure state in the partial space 3 is improved, which is convenient.
[0027]
Next, a method of using the smoking space creation system 1 having the above configuration will be described.
First of all, the empty space in the room 3 is investigated, the ceiling height, the airflow situation, the use situation of the adjacent space, etc. are investigated for each empty space, and it is most convenient to introduce the smoking space creation system 1 among them. A free space with many good walls 13 is selected. Then, installing the free space, i.e. the pipe type air curtain generator 6 so as to surround the part of the area 3. The air flow conditions, be determined the dimension and speed of air blowing outlet 5 of the pipe type air curtain generator 6 determines the air curtain air volume depends also air emissions from the air suction amount and the discharge port 48 from the suction port 37, The supply / discharge amount of air is determined, and a blower 38 corresponding to the supply / discharge amount is selected.
[0028]
Then, the part of the area 3 and the enclosure smoking space 9 by the air curtain 4 from the outlet 5 of the pipe type air curtain generator 6, when operating the blower 38, the smoke near the air cleaner 30 is immediately from the suction port 37 is sucked by tornado t, but clean air from the outlet 48 is cleaned by the air cleaning unit 34 is discharged, the clean air is, the smoking space creation system 1 of Figures 1-5, the floor 15 by the guide 49 crawling Then, it passes through the gap 16 under the air curtain 4 and exits from the partial space 3 to bring the partial space 3 into a negative pressure state.
[0029]
Moreover, in the smoking space creation system 1 of FIGS. 13-14 , smoke is suction-cleaned by the air cleaner 30a, and the clean air from the discharge port 48 passes over the ceiling 14, and the clearance 16 above the air curtain 4, that is, since the top of the pipe type air curtain generator 6 is adjuster 29 is not air curtain 4 is formed, to go out 3 through part of the area of the gap 16 on the air curtain 4, a part space 3 Set to negative pressure state.
[0030]
At this time, if the amount of air discharged from the discharge port 48 is set to the external entrainment air amount Q or more or 2Q or more, the smoking space 9 appears in a favorable negative pressure state, and even if the cigarette is sucked therein, Smoke is sucked and exhausted from the suction port 5 without leaking to the outside, and is discharged outside the partial space 3. In particular, if the air discharge amount is set to 2Q or more, it can withstand severe air currents, and complaints from people who do not smoke or smokers will not come.
[0031]
In addition, it goes without saying that the smoking space creation system of the present invention can be used as a system in which not only cigarette smoke but also harmful gas is contained in a part of the room and does not flow directly out of the part of the room. Is within the scope of the present invention.
[0032]
