Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ventilation structure for a smoking room provided under the floor of a high decker type bus such as a large sightseeing bus or a long-distance bus.
[0002]
[Prior art]
Conventionally, a trunk room for storing luggage is provided under the floor of a high-decker bus such as a large sightseeing bus or a long-distance bus, and the luggage can be taken in and out by opening and closing the lid on the side of the vehicle body. This trunk room is a space where people can enter, although there are height restrictions.
[0003]
Therefore, in recent years, it has been proposed that a staircase is provided so that passengers can enter and exit the underfloor space where the trunk room was conventionally provided, and that it is equipped with air conditioning and lighting facilities to make it a nap room for drivers and passengers. (For example, refer to Japanese Utility Model Laid-Open No. 2-143338).
Furthermore, in response to the recent increase in international smoking cessation and smoking consciousness, smoking is undertaken in the above floor space so as not to bother non-smokers and to impose patience on smokers. There is also a proposal for a room.
[0004]
[Problems to be solved by the invention]
However, as described above, even if the under floor is separated from the vehicle interior as a smoking room, smoke in the smoking room does not completely separate if smoke flows into the vehicle interior, causing discomfort to non-smokers. There is a risk of it. On the other hand, if the smoking room is sealed with a door so that cigarette smoke does not leak, this will adversely affect the health of the smoker in the smoking room. Therefore, it is desired to efficiently ventilate the smoking room and to enable a comfortable bus trip for both non-smokers and smokers.
[0005]
The above-mentioned problem is not limited to the case where the smoking room is provided below the floor, but is common to the case where the smoking room is provided by separating the passenger room from the same floor.
The present invention has been made in view of such problems, and an object of the present invention is to provide a ventilation structure for a smoking room of a bath that can efficiently ventilate a room.
[0006]
[Means for Solving the Problems]
For this reason, in the ventilation structure of the smoking room of the bus of the present invention, an exhaust device that exhausts the air in the smoking room provided separately from the passenger cabin to the outside of the vehicle is provided, and the exhaust port of the exhaust device is provided on the bottom of the bus body. By disposing, ventilation in the smoking room is performed using negative pressure at the bottom of the vehicle body. Further, by arranging the intake port of the exhaust device in the upper part of the smoking room, the smoke of tobacco flowing upward is efficiently captured.
[0007]
Preferably, the smoking room is provided under the floor of the passenger cabin.
More preferably, a stairway for moving up and down between the smoking room and the passenger cabin and a left and right wall at the entrance of the smoking room communicating with the staircase are provided, and air is sucked into the upper part of one of the left and right walls. An opening is provided, and an air supply opening for supplying conditioned air to the smoking room is provided above the other wall.

The other sheet 12 is for two persons and is a fixed sheet in which a stool portion 22a and a backrest portion 22b are fixed. A common table 23 is disposed between the sheets 21 and 22 and is fixed to the floor surface 6.
[0011]
As shown in FIG. 5, the lid 50 provided on the side portion of the vehicle body 2 serves as the side wall of the underfloor smoking room 1. Here, as shown in FIGS. 2 and 6, two lids 50A and 50B are used as side walls. Of these two lids 50A and 50B, the lid 50B on the fixed sheet side provided with the window 53 is fixed in the closed state, but the lid 50A on the flip-up sheet 21 side is configured as a flip-up type open / close lid. It is designed to function as an emergency exit. For this reason, a lid (opening / closing lid) 50A is provided with an opening / closing handle 51 and a plate 52 for explaining an emergency escape procedure.
[0012]
Further, to prevent the opening / closing lid 50A from being accidentally opened during operation, the opening / closing lid 50A and the seat 21a of the flip-up seat 21 are provided with key-like members 60, 61, respectively. Are engaged with each other to restrain the open / close lid 50A to the closed state. Therefore, when opening the opening / closing lid 50A, an operation of raising the seat 21a and releasing the engagement of the key-like members 60 and 61 is required. Further, a locking device 63 is provided for restraining the key-like members 60 and 61 so that the opening / closing lid 50A cannot be opened when the vehicle speed exceeds a predetermined speed.
[0013]
The underfloor smoking room 1 is provided with lighting equipment such as a ceiling light 14 and a footlight 15, and safety equipment such as a fire extinguisher 16, an emergency telephone (not shown) and a smoke detector.
Furthermore, an air supply port 41 and an air intake port 31 as ventilation equipment are provided in the upper portions of the left and right walls 10 and 11 of the inlet portion. The air supply port 41 is connected to an air conditioner (not shown) and an air supply pipe 42 so that the conditioned air adjusted to a predetermined temperature by the air conditioner is supplied into the underfloor smoking room 1 through the air supply pipe 42. It has become.
[0014]
On the other hand, the intake port 31 is connected to an exhaust pipe 32 formed by dividing the inside of the wall 11. An exhaust device 33 is provided below the exhaust pipe 32. As shown in FIG. 7, the exhaust device 33 includes a fan 35 and a motor 36 that drives the fan 35, and a plurality of brackets 37, 38, and 39 are attached to the wall 11 and the floor surface (vehicle bottom surface) 6. Is fixed. A suction port 35a of the fan 35 is attached to an outlet hole 32a provided in the exhaust pipe 32, and the exhaust port 34 penetrates the floor surface 6 downward and projects outside the vehicle. Further, the exhaust port 34 is provided with a slight inclination toward the rear of the vehicle.
[0015]
Since the ventilation structure of the smoking room of the bus as one embodiment of the present invention is configured as described above, the ventilation of the smoking room is performed as follows.
In other words, cigarette smoke is lighter than air and has a property of flowing upward, but since there is no partition between the underfloor smoking room 1 and the staircase 4, tobacco smoke generated in the underfloor smoking room 1 It tries to flow into the passenger cabin 3 through the stairs 4. However, in the underfloor smoking room 1, the air inlet 31 is provided above the wall 11 at the entrance, and the air accumulated in the underfloor smoking room 1 is sucked up. Cigarette smoke is sucked into the air inlet 31.
[0016]
The tobacco smoke sucked into the intake port 31 passes through the exhaust pipe 32 and is exhausted from the exhaust port 34 to the outside by the exhaust device 33. The exhaust efficiency of the exhaust device 33 at this time is affected by the pressure difference between the pressure on the suction port 35a side and the pressure on the exhaust port 34 side. In the underfloor smoking room 1, the exhaust port 34 is provided on the bottom surface 6 of the vehicle body. However, since the air flow at the bottom surface 6 of the vehicle body becomes very fast depending on the vehicle speed, the static pressure at the outlet of the exhaust port 34 is It decreases according to the flow velocity of the air flowing through the bottom surface 6 of the vehicle body. For this reason, a pressure difference occurs between the suction port 35a side and the exhaust port 34 side, and the exhaust efficiency of the exhaust device 33 is improved by this pressure difference. Therefore, in the under-floor smoking room 1, the smoke of the cigarette can be efficiently sucked into the intake port 31 using the negative pressure in the bottom surface 6 of the vehicle body, and the outflow of the smoke of the cigarette to the staircase 4 side is suppressed.
[0017]
As described above, according to the ventilation structure of the smoking room of the bus as one embodiment of the present invention, the negative pressure is utilized by disposing the exhaust port 34 of the exhaust device 33 on the bottom surface 5 of the bus body. Since the efficiency of sucking tobacco smoke from the air inlet 31 can be increased, there is an advantage that the ventilation in the subfloor auxiliary chamber 1 can be efficiently performed. Therefore, there is an advantage that cigarette smoke does not easily flow into the passenger compartment 3 through the stairs 4 and does not cause discomfort to passengers in the passenger cabin 3.
[0018]
In addition, the possibility of cigarette smoke flowing into the passenger cabin 3 through the stairs 4 without the need to provide a highly airtight partition with the stairs 4 is reduced, so there is no need to seal the underfloor smoking room 1, The advantage that the smoker in the underfloor smoking room 1 is not obstructed, and that the partition of the underfloor smoking room 1 can be simplified, such as partitioning the underfloor smoking room 1 and the stairs 4 with a simple means such as a curtain. There are advantages. In addition, the efficiency of sucking cigarette smoke from the air inlet 31 is high, and the conditioned air is supplied from the air inlet 41, so that there is also an advantage that a smoker can smoke in a comfortable environment.
[0019]
Furthermore, in this embodiment, since the smoking room 1 is provided under the floor, the distance from the intake port 31 to the exhaust port 34 can be shortened, and pressure loss can be reduced to efficiently ventilate the smoking room 1. There is also an advantage of being able to.
Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the case where the smoking room is provided under the floor has been described. However, the installation location of the smoking room is not limited, and the exhaust port may be provided even when the smoking room is provided on the same floor as the passenger cabin. By opening at the bottom of the vehicle body, the same effect as in the above embodiment can be obtained.
[0020]
【The invention's effect】
As described above in detail, according to the ventilation structure of the smoking room of the present invention, the exhaust port of the exhaust device is disposed on the bottom surface of the vehicle body of the bus. efficiently it is advantageous cormorants have to be able to perform. Further, since the intake port of the exhaust device is disposed in the upper part of the smoking room, the smoke of the cigarette flowing upward can be captured efficiently (claim 1).
Further, when the smoking room is provided under the floor, the distance to the exhaust port can be shortened to reduce the pressure loss, and there is an advantage that the smoking room can be ventilated more efficiently (claims). 2).
