以下、本発明の実施形態を、図面に基づいて説明する。
図1は、本発明を適用した喫煙ブースにおける第1の実施形態の斜視図で、喫煙ブース(1)は、床板(2)と、天井板(3)と、前面板(以下、図1の右面側を前として説明する)(4)と、後面板(5)と、左側面板(6)と、右側面板(7)とにより囲まれた箱部屋状をなし、ブース内には、複数の喫煙者が入室しうるようになっている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a first embodiment of a smoking booth to which the present invention is applied. The smoking booth (1) includes a floor panel (2), a ceiling panel (3), a front panel (hereinafter referred to as FIG. 1). (It will be described with the right side as the front) (4), rear side plate (5), left side plate (6) and right side plate (7). Smokers can enter the room.

前面板(4)の左半部に形成された出入口(8)には、取っ手(9)を回動操作することにより、前方に開かれる開閉扉(10)が取付けられ、また中央部には、透明なガラス(11)が嵌め込まれている。   The doorway (8) formed in the left half of the front plate (4) is attached with an opening / closing door (10) that opens forward by rotating the handle (9), and in the center part. Transparent glass (11) is fitted.

左側面板(6)は、複数(4枚)の透明なガラスパネル(12)を前後方向に連結して形成されている。   The left side plate (6) is formed by connecting a plurality (four) of transparent glass panels (12) in the front-rear direction.

天井板(3)の中央部下面には、右側面板(7)と平行をなす前後方向を向く気流偏向板(13)が、天井板(3)の下面との間に所要の隙間(S)が形成されるようにして、複数のブラケット(13a)により垂下状に取付けられている(図2参照)。なお、ブラケット(13a)を用いないで、気流偏向板(13)の前後両端を、前面板(4)と後面板(5)とに固定してもよい。   On the lower surface of the center part of the ceiling plate (3), an airflow deflector plate (13) facing in the front-rear direction parallel to the right side plate (7) is provided with a required gap (S) between the lower surface of the ceiling plate (3). Is formed so as to be suspended by a plurality of brackets (13a) (see FIG. 2). Note that the front and rear ends of the airflow deflector plate (13) may be fixed to the front plate (4) and the rear plate (5) without using the bracket (13a).

右側面板(7)は、図2及び図3に示すように、外パネル(7a)と内パネル(7b)との内外二重構造をなし、それらの対向面間の内部空間は、密閉された通風路(14)となっている。   As shown in FIGS. 2 and 3, the right side plate (7) has an inner / outer double structure of the outer panel (7a) and the inner panel (7b), and the inner space between the facing surfaces is sealed. Ventilation path (14).

通風路(14)内は、その下方寄りに設けた仕切板(15)により、下部の給気路(16)と上部の排気路(17)とに仕切られている。   The ventilation path (14) is partitioned into a lower air supply path (16) and an upper exhaust path (17) by a partition plate (15) provided near the lower side.

また、図3に示すように、通風路(14)の後部側の一部は、排気路(16)と区画された、上下方向を向く給気ダクト(18)となっており、この給気ダクト(18)の下端部と給気路(16)とは、連通孔(19)を介して互いに連通し、図示しないエアフィルタを通過した新鮮な空気が、天井板(3)に開口した給気孔(図示略)より、給気ダクト(18)及び給気路(16)に流入するようになっている。   Further, as shown in FIG. 3, a part of the rear side of the ventilation path (14) is an air supply duct (18) which is partitioned from the exhaust path (16) and faces in the vertical direction. The lower end of the duct (18) and the air supply passage (16) communicate with each other via the communication hole (19), and fresh air that has passed through an air filter (not shown) is opened to the ceiling plate (3). From the air holes (not shown), the air flows into the air supply duct (18) and the air supply path (16).

給気路(16)内の下部において床板(2)の上面には、例えばクロスフローファン(シロッコファン)等よりなる前後2基の給気ファン(20)(20)が、送風口(20a)を内パネル(7b)に向けて設置されている。   Two front and rear air supply fans (20, 20) made of, for example, a cross-flow fan (sirocco fan) are provided on the upper surface of the floor plate (2) in the lower part of the air supply path (16). Is facing the inner panel (7b).

内パネル(7b)における給気ファン(20)の送風口(20a)と対向する面には、前後方向を向くスリット状の空気の吹出口(21)(21)が穿設されている。各吹出口(21)には、下向きにセットされた可動ルーバが設けられており、これにより、各給気ファン(20)より吐出された空気は、各吹出口(21)を介して、ブース(1)内にやや下向きに吹出されるようになっている(図2参照)。   On the surface of the inner panel (7b) facing the air blowing port (20a) of the air supply fan (20), slit-shaped air blowing ports (21, 21) facing the front-rear direction are formed. Each air outlet (21) is provided with a movable louver set downward, so that the air discharged from each air supply fan (20) passes through each air outlet (21) to the booth. In (1), it is blown out slightly downward (see FIG. 2).

仕切り板(15)よりも上方、すなわち排気路(17)と面する部分の内パネル(7b)には、上下及び前後方向に並ぶ4個の広面積の排風口(22)が開口され、各排風口(22)には、図4に示すように、内パネル(7b)の一部をなす、多数の吸込孔(23)が穿設された方形の排気パネル(24)が、ねじ(25)により着脱可能に取付けられている。   On the inner panel (7b) above the partition plate (15), that is, the portion facing the exhaust passage (17), four wide area exhaust ports (22) arranged in the vertical and front-rear directions are opened. As shown in FIG. 4, a square exhaust panel (24) having a plurality of suction holes (23) formed as a part of the inner panel (7 b) is formed in the exhaust port (22). ) Is detachably attached.

下部の2枚の排気パネル(24)の吸込孔(24)の直径は、上部の2枚の排気パネル(24)の吸込孔(23)の直径よりも大とされている。
例えば本実施形態では、上下の各排気パネル(24)における吸込孔(23)の開口率が、それぞれ約10%と20%になるように、それらの吸込孔(23)の直径を定めてある。
The diameters of the suction holes (24) of the two lower exhaust panels (24) are larger than the diameters of the suction holes (23) of the upper two exhaust panels (24).
For example, in this embodiment, the diameters of the suction holes (23) are determined so that the opening ratios of the suction holes (23) in the upper and lower exhaust panels (24) are about 10% and 20%, respectively. .

また、下部の排気パネル(24)の上端の床板(2)からの高さは、180cm前後とされ、平均的な身長の喫煙者の頭部付近が、下部の排気パネル(24)の上部に位置するようにしてある。これは、喫煙者から吐き出されたタバコの煙が、開口率を大とした下部の排気パネル(24)の吸込孔(23)より速やかに吸引されるようにするためである。   Also, the height of the lower exhaust panel (24) from the top floor plate (2) is about 180cm, and the average height of the smoker's head is located above the lower exhaust panel (24). It is supposed to be located. This is because the smoke of tobacco discharged from the smoker is quickly sucked from the suction hole (23) of the lower exhaust panel (24) having a large aperture ratio.

天井板(3)の排気路(17)と面する部分には、前後2個の排気孔(26)(26)が間隔をおいて穿設され、各排気孔(26)は、連通管(27)と、その中央部に連結された排気管(28)とを介して、排気ファン(29)を有する排気ユニット(30)に接続されている。   In the portion of the ceiling plate (3) facing the exhaust passage (17), two front and rear exhaust holes (26), (26) are formed at intervals, and each exhaust hole (26) is connected to a communication pipe ( 27) and an exhaust pipe (28) connected to the center thereof, and is connected to an exhaust unit (30) having an exhaust fan (29).

内パネル(7b)における給気路(16)と排気路(17)との境界部、すなわち下部の排気パネル(24)のやや下方の内側面には、灰皿等を載置するための棚板(31)が、複数のブラケット(32)により取付けられている。棚板(31)は、灰皿等の載置用だけでなく、吹出口(21)より吐出する空気を、ブース(1)の内方に向かわせる偏向板としての機能も有している。   A shelf for placing an ashtray or the like on the boundary between the air supply passage (16) and the exhaust passage (17) in the inner panel (7b), that is, on the inner surface slightly below the lower exhaust panel (24) (31) is attached by a plurality of brackets (32). The shelf plate (31) has a function not only for mounting an ashtray or the like, but also as a deflecting plate for directing air discharged from the air outlet (21) to the inside of the booth (1).

上記実施形態の喫煙ブース(1)において、喫煙者のタバコの煙や臭いを排出し、室内を換気するには、給気ファン(20)と排気ユニット(30)の排気ファン(29)を共に作動させて行う。   In the smoking booth (1) of the above embodiment, both the air supply fan (20) and the exhaust fan (29) of the exhaust unit (30) are used to exhaust the smoke and smell of the smoker and ventilate the room. Operate to do.

給気ファン(20)を作動させると、新鮮な空気が、給気ダクト(18)及び給気路(16)内に流入し、図2の矢印で示すように、内パネル(7b)の下端部の2個の吹出口(21)より、ブース(1)内の底部に向かって吹出され、左側面板(6)の内面に沿って上方に流れる。そして、天井板(3)の下面に達した空気は、右側方に向かって流れ、一部の空気は気流偏向板(13)により、ブース(1)内の中央部に向かって下向きに偏向されるとともに、一部の空気は、天井板(3)と気流偏向板(13)との間の隙間(S)を通って右側方に向かって流れる。   When the air supply fan (20) is activated, fresh air flows into the air supply duct (18) and the air supply passage (16), and as shown by the arrows in FIG. 2, the lower end of the inner panel (7b). From the two outlets (21) of the section, the air is blown toward the bottom of the booth (1) and flows upward along the inner surface of the left side plate (6). And the air which reached the lower surface of the ceiling board (3) flows toward the right side, and a part of the air is deflected downward toward the central part in the booth (1) by the airflow deflector (13). At the same time, part of the air flows toward the right side through the gap (S) between the ceiling plate (3) and the airflow deflector plate (13).

一方、排気ファン(29)の同時作動により、排気路(17)内が減圧されているため、各排気パネル(24)の多数の吸込孔(23)には、ブース内の空気を吸い込む吸引力が作用している。   On the other hand, since the exhaust passage (17) is depressurized by the simultaneous operation of the exhaust fan (29), the suction force for sucking the air in the booth into the numerous suction holes (23) of each exhaust panel (24) Is working.

そのため、ブース(1)内の底部に流入した空気の一部、気流偏向板(13)により下向きに偏向された空気、及び隙間(S)を通過した空気は、図2の矢印に示すように、上下の排気パネル(24)に向かって流れ、それらの吸込孔(23)により吸引されて排気路(17)に流入したのち、上方に向かい、連通管(27)及び排気管(28)を介してブース(1)外に排出される。   Therefore, a part of the air flowing into the bottom of the booth (1), the air deflected downward by the airflow deflector plate (13), and the air passing through the gap (S) are as shown by arrows in FIG. Then, it flows toward the upper and lower exhaust panels (24), is sucked by the suction holes (23) and flows into the exhaust passage (17), and then upwards, through the communication pipe (27) and the exhaust pipe (28). Through the booth (1).

このような空気の流れに乗って、ブース(1)内の隅々まで充満しているタバコの煙や臭い等が、排気パネル(24)の広い領域で速やかに外部に排出される。   The smoke and odors of cigarettes filled in every corner of the booth (1) riding on such air flow are quickly discharged outside in a wide area of the exhaust panel (24).

しかも、開口率を大とした下部の2枚の排気パネル(24)は、喫煙者の頭部付近の高さとしてあるため、喫煙時のタバコの煙は、室内に充満する前に即座に吸引されて排出される。   In addition, the lower two exhaust panels (24) with a large aperture ratio have a height near the head of the smoker, so the tobacco smoke during smoking is immediately sucked before it fills the room. Is discharged.

また、棚板(31)に載置された灰皿に置いたタバコの副流煙も、その上部の開口率の大きな排気パネル(24)より速やかに吸引されて排出される。   Further, the sidestream smoke of the cigarette placed on the ashtray placed on the shelf board (31) is also quickly sucked and discharged from the exhaust panel (24) having a large opening ratio.

図5は、本発明の第2の実施形態を示すもので、この実施形態では、排気路(17)の下方に形成された給気路(16)を、その中間部において仕切板(33)により上下に仕切り、上部側を空気導入室(34)に、下部側を整風室(35)にするとともに、空気導入室(34)内における仕切板(33)の上面に、上記第1の実施形態と同様、前後2基のクロスフローファン等よりなる給気ファン(20)を載設してある。   FIG. 5 shows a second embodiment of the present invention. In this embodiment, an air supply passage (16) formed below the exhaust passage (17) is divided into a partition plate (33) at an intermediate portion thereof. The upper side is divided into the air introduction chamber (34), the lower side is made into the air conditioning chamber (35), and the upper surface of the partition plate (33) in the air introduction chamber (34) is arranged in the first embodiment. As with the embodiment, an air supply fan (20) including two front and rear cross flow fans is mounted.

空気導入室(34)は、上記と同様の給気ダクト(18)に、連通孔(36)を介して連通されている。   The air introduction chamber (34) communicates with an air supply duct (18) similar to the above via a communication hole (36).

給気ファン(20)を作動させると、給気ダクト(18)を介して空気導入室(34)に流入した新鮮な空気は、給気ファン(20)の送風口(20a)と対向する仕切板(33)に穿設された連通孔(37)を通して、整風室(35)に送風され、吹出口(21)よりブース(1)内に供給される。   When the air supply fan (20) is operated, the fresh air that has flowed into the air introduction chamber (34) through the air supply duct (18) is separated from the air supply fan (20) by the air outlet (20a). The air is blown into the conditioned chamber (35) through the communication hole (37) drilled in the plate (33), and is supplied into the booth (1) from the outlet (21).

この第2の実施形態のように、整風室(35)を設けると、給気ファン(20)より送風される空気が、整風室(35)内において一定の圧力に蓄圧され、前後の吹出口(21)より一定圧で吹出されるため、ブース室内は均一に、かつ効率よく換気されるようになる。   When the air conditioning chamber (35) is provided as in the second embodiment, the air blown from the air supply fan (20) is accumulated at a constant pressure in the air conditioning chamber (35), and the front and rear outlets are provided. (21) Since the air is blown out at a constant pressure, the booth room is uniformly and efficiently ventilated.

本発明は、上記実施形態に限定されるものではない。
上記実施形態では、ブース(1)内の中央部に滞留するタバコの煙等を効果的に排出するために、気流偏向板(13)を設けているが、ブース(1)が比較的小型の際には、気流偏向板(13)を省略することもある。
The present invention is not limited to the above embodiment.
In the above embodiment, the airflow deflector (13) is provided in order to effectively discharge cigarette smoke and the like staying in the center of the booth (1), but the booth (1) is relatively small. At this time, the airflow deflector (13) may be omitted.

また、上記実施形態では、気流偏向板(13)と天井板(3)との間に隙間(S)を設けているが、この隙間の代わりに、気流偏向板(13)に複数の通気孔を設けたり、ブース(1)の大きさ等によっては、隙間(S)をなくしたりしてもよい。   Moreover, in the said embodiment, although the clearance gap (S) is provided between the airflow deflection | deviation plate (13) and the ceiling board (3), several ventilation holes are provided in the airflow deflection | deviation plate (13) instead of this clearance gap. Or the gap (S) may be eliminated depending on the size of the booth (1).

さらに、上記実施形態では、ブース(1)の右側面板(7)の内面のみより、タバコの煙等を排出するようにしているが、ブース(1)を大型とした際などには、上記と同様の換気手段を、2側面以上に複数設けてもよい。   Further, in the above embodiment, cigarette smoke and the like are discharged only from the inner surface of the right side plate (7) of the booth (1). A plurality of similar ventilation means may be provided on two or more side surfaces.

排気ユニット(30)を作動させると、ブース(1)内が負圧となり、下部の吹出口(21)より空気が自然に流入するので、比較的小型のブース(1)とした際などには、給気ファン(20)を省略することもある。   When the exhaust unit (30) is activated, the inside of the booth (1) becomes negative pressure and air naturally flows in from the lower outlet (21). The air supply fan (20) may be omitted.

給気ダクト(18)を省略し、外パネル(7a)に接続した空気の導入経路等より、空気が、給気路(16)又は空気導入室(34)内に直接流入するようにしてもよい。このようにすると、給気ダクト(18)を省略した分、内パネル(7b)の内側面に、大きな排気パネル(24)を取付けることができるので、排気効率を高めることができる。   The air supply duct (18) may be omitted, and air may flow directly into the air supply path (16) or the air introduction chamber (34) from the air introduction path connected to the outer panel (7a). Good. In this way, since the large exhaust panel (24) can be attached to the inner surface of the inner panel (7b), the exhaust efficiency can be improved by the amount that the air supply duct (18) is omitted.

上記実施形態では、排気パネル(24)が汚れたときの清掃又は交換を容易とするために、排気パネル(24)を、内パネル(7b)に着脱可能に装着しているが、このような排気パネル(24)を省略して、内パネル(7b)に、吸込孔(23)を直接穿設してもよい。この際、吸込孔(23)の径や個数を、下方に向かうほど漸次大とするようにするのがよい。
本発明は、上記喫煙ブース以外に、例えば臭気が発生する実験室等、換気が必要な種々のブースにも適用することができる。
In the above embodiment, the exhaust panel (24) is detachably attached to the inner panel (7b) in order to facilitate cleaning or replacement when the exhaust panel (24) becomes dirty. The exhaust panel (24) may be omitted, and the suction hole (23) may be directly drilled in the inner panel (7b). At this time, the diameter and the number of the suction holes (23) are preferably gradually increased toward the lower side.
In addition to the smoking booth, the present invention can also be applied to various booths that require ventilation, such as laboratories where odors are generated.
