2. Related Art Unlike a train in which a plurality of vehicles are connected, it is difficult for a passenger aircraft to spatially partition the interior of the cabin into a non-smoking seat area and a smoking seat area. Therefore, in the cabin, only the non-smoking seat area and the smoking seat area are divided according to the seat arrangement. In recent years, comparing the number of seats in the non-smoking seat area and the number of seats in the smoking seat area, the non-smoking seat area tends to increase, and it is becoming difficult for smokers to secure a seat in the smoking seat area.

[0003] Under such circumstances, it is conceivable to make the last row of seats in the smoking seat area unreserved for the convenience of passengers who have been allocated to the non-smoking seat area. If such unreserved seats are secured in the cabin, even a passenger having a seat in the non-smoking seat area can smoke in the unreserved seat.

[0004]

However, if there are many passengers allocated to the non-smoking seat area, the non-smoking seat area will be replaced by unreserved seats, and passengers will come to the site. In such a situation, tobacco smoke and smell will appear at the rear of the smoking area, which is annoying to passengers in the smoking area.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a passenger seat in which a rear seat in a passenger aircraft is reserved as a free seat for smokers.
It is an object of the present invention to provide a smoke separating device and a smoking method in an in-flight aircraft that are suitable for smoking in an in-flight machine without causing tobacco smoke and odor caused by smoking in a rear seat to stay around the free seat.

[0006]

8 are provided one by one, and the auxiliary seat 70 is used by being pulled down from the partition 68 as needed.
Note that the auxiliary seat 70 is a spare seat like the last row seat 50.

Next, the left and right air supply grills 48L,
The operation of the smoke separating apparatus including 48R, that is, the method of separating smoke will be described. The left and right air supply grills 48L, 48R supply conditioned air from the line outlet 40 to each air supply inlet 58.
The conditioned air is blown into the first floor cabin from the corresponding air supply port 54 while guiding the conditioned air to the inner surface of the air supply deflector 60 and the side guide plates 64 and 66. Here, as described above, each air supply deflector 60 has a shape that faces obliquely rearward with respect to the grill surface of the air supply grille 48 and gradually expands. The conditioned air is blown obliquely rearward (45 °) and obliquely downward (45 °) of the body 2 from the respective air supply ports 54 into the cabin on the first floor. That is, conditioned air is blown from the grill surface of the air supply grill 48 as shown by solid arrows in FIG. 4 and as shown by white arrows in FIG. The blowout of the conditioned air from the left and right air supply grills 48L and 48R is symmetrical with respect to the axis of the body 2 and the blowout amount is also the same. Therefore, the left and right air supply grills 48L, 4
The conditioned air blown out from the 8R is mainly the last row seat 5
Above 0L and 50R, it is blown down as shown by the white arrow in FIG. 2, and flows behind the cabin on the first floor.

Therefore, even if a passenger undesirably allocated to the non-smoking seat area alternates with the left and right rear row seats 50L, 50R and the auxiliary seat 70, and then smokes there, the smoke and smell of the tobacco will not increase. Left and right air supply grills 48
The air is guided to the rear of the first-floor cabin together with the conditioned air blown out from L and 48R, so that the smoke and smell of tobacco do not enter the vicinity of the rearmost seat 50. As a result, tobacco smoke and odor stay around the left and right rear row seats 50L and 50R, and do not bother passengers in the smoking seat area.

Further, as described above, if the exhaust port 24 is provided on the outer floor surface of the lavatory module 18,
Since the air is exhausted from the rear of the floor cabin through the exhaust port 24, the smoke and smell of the tobacco collected at the rear of the first floor cabin by the blowout of the conditioned air from the left and right air supply grills 48L and 48R is reduced. Is discharged from The air exhausted in this manner passes through the cargo space and is discharged outside the machine from the outflow valve.

FIG. 8 shows that when smoking in the last seat 50L,
The result of simulating the tobacco smoke flow is shown. That is, in this case, the smoke of the tobacco is represented by a white circle. In this case, as the conditioned air is blown out from the air supply grill 48L, the smoke of the tobacco flows toward the upper part of the last row seat 50L as shown by the flow of the white circle, and the rear of the last row seat 50L together with the conditioned air. That is, it is guided to the exhaust port 24.

On the other hand, FIG. 8 also shows the result of a simulation in which conditioned air is blown straight from the line outlet 40 toward the aisle side of the first-floor cabin by solid arrows. In this case, the smoke in the last row seats 50L
It turns out that it rises while turning, flows toward the central row of seats 9, and stays around the last row of seats 50L.

The present invention is not limited to the above-described embodiment, but can be variously modified. For example, when the auxiliary seat unit 68 is not provided, left and right end column seats 50L, 50R may also be against the seat row in the front, it arranged in front and rear reversed. In this case, since the smoker in the rearmost row seat is facing the exhaust port 24 side, the smoke and smell of the tobacco are not disturbed by the backrest of the seat, and the smoker and the odor in the rear of the first-floor cabin together with the conditioned air . Exhaust port 2
4 is well guided.

The left and right air supply grills 48L, 48R are not limited to being provided above the last row seats, and may extend from the last row seats to several rows of seats. Is not limited to the lower side of the baggage storage row 42, but may be installed on the ceiling between the left and right seat rows and the center seat row.
