Exhaust air discharged from the cabins of the high roof portion A and the low roof portion B of the leading vehicle 1a to the outside of the vehicle is discharged by the exhaust air blower of the air conditioner 17 from the exhaust air intake formed in the ceiling panel below the air conditioner 17. Is done. The exhaust air from the entrance 75 of the low roof portion B and the toilet unit 26 was sent to the exhaust intake port by the exhaust duct 86 disposed from the ceiling portion of the toilet unit 26 to the ceiling portion of the high roof portion A. Then, it is discharged outside the vehicle by the exhaust fan of the air conditioner 17.

4 is a cross-sectional view (cross-section EE in FIG. 2) in which the connecting portion between the high roof portion A and the low roof portion B intersects the width direction of the railcar, and FIG. 5 shows the high roof portion A and the low roof portion. It is sectional drawing which expanded the connection part with the part B (F part of FIG. 4).
As shown in FIG. 5, the conditioned air blown to the cabin of the low roof portion B is a conditioned air duct 94 disposed between the high roof structure 36 where the air conditioner 17 is installed and the ceiling panel 83a. The conditioned air duct 94 is supplied by a connecting duct 93 having one end connected to the conditioned air duct 94 and a conditioned air duct 80 connected to the other end of the connecting duct 93.

The connection duct 93 is a flow path (duct) that smoothly bends in the height direction at the connection portion between the high roof structure 36 and the low roof structure 34, and the conditioned air duct 80 is positioned below the low roof structure 34. An annular channel including a substantially rectangular shape is formed by the ceiling panel 83b.
The ceiling panel 83b extends to the high roof portion A side to the vicinity of the connection portion between the connection duct 93 and the conditioned air duct 94. Further, a heat insulating material 85 that suppresses heat in and out of the inside of the vehicle and the outside of the vehicle is attached to the entire surface of the low roof structure 34 and the high roof structure 36 on the vehicle interior side.

The conditioned air duct 80 includes a vertical piece 80a, a horizontal piece 80b, and a slant piece 80c, and a channel member (for example, a groove member having a C-shaped cross section) having an open surface toward the ceiling panel 83b. And the ceiling panel 83b. The open surface (open portion) of the flow path is a vertical piece 80a, a horizontal piece 80b, and a ceiling panel 83b substantially parallel to the horizontal piece 80b. Configured.

A horizontal end portion 80ce extends in parallel to the ceiling panel 83b at the lower end portion of the slant piece 80c, and the conditioned air is annularly and horizontally between the opening provided in the ceiling panel 83b. A conditioned air outlet 87 is formed toward the central portion of the conditioned air duct 80.
The outlet 87 is formed along the inner edge (center side) of the flow path (duct) formed by the annular conditioned air duct 80. The conditioned air branches into the conditioned air duct 80 by branching in a direction intersecting the direction of the conditioned air flowing through the connection duct 93 as indicated by an arrow 99. The conditioned air is blown out toward the central portion of the conditioned air duct 80 in a substantially horizontal direction in the process of flowing along the annular conditioned air duct 80.

A lighting device 81 (see FIG. 3) is provided annularly along the inner peripheral side of the conditioned air duct 80 adjacent to the outlet 87, and the outer peripheral edge of the lighting device 81 is the inner peripheral edge of the horizontal end 80ce. Is close to.
The illuminating device 81 includes a light source such as an LED and a diffusing plate 88 for diffusing light emitted from the light source in the horizontal direction. Further, a broadcasting facility (speaker) 82 (see FIG. 4) is provided at the center of the illuminating device 81. Is attached).
The diffusing plate 88 is disposed substantially in parallel with the horizontal end portion 80ec constituting the blowout port 87, and guides conditioned air blown out from the blowout port 87 in a substantially horizontal direction.

The procedure for assembling the ceiling of the low roof portion B will be described with reference to FIG.
First, the channel material composed of the vertical piece 80a, the horizontal piece 80b, and the oblique piece 80c and the ceiling panel 83b are connected by an outwork to manufacture the ceiling module 92 in which the conditioned air duct 80 is built.

Next, one end of the connection duct 93 is connected to the conditioned air duct 94 fixed to the high roof structure 36 in advance. A packing 90 a that suppresses air leakage is attached to the periphery of the other end of the connection duct 93.
Further, an illumination device 81, a broadcasting facility 82, and the like are fixed to the lower surface of the low roof structure 34, and a packing 90b is attached to the lower surface of the diffusion plate 88.

The ceiling module 92 is positioned, and the ceiling module 92 (ceiling panel 83b) is fixed to the support portion 95 extending below the low roof structure 34 while pressing the upper surface thereof against the packing 90a and the packing 90b from below.
When manufacturing the ceiling module 92, the broadcasting equipment 82, the lighting device 81, and the like may be attached in advance and integrated.

FIG. 6 is a cross-sectional view (GG cross section in FIG. 4) intersecting the longitudinal direction of the end portion in the width direction of the low roof portion. The low roof structure 34 of the low roof portion B is composed of an end slope 34a that descends obliquely from the upper end 35 of the side structure 32, and a horizontal portion 34b that is connected to the end slope 34a. The current collector 16 and the like are provided on the upper part of the horizontal part 34b.
The space 91 surrounded by the upper end portion 35 and the end slope 34a of the side structure 32 has a relatively large height because it is the same height as the high roof portion A even in the range of the low roof portion B. By utilizing this, the conditioned air duct 89 (see FIG. 3) can be arranged continuously from the exhaust duct 86 and the conditioned air duct 94 arranged in the high roof portion A.

In addition, a slit 96 is provided in a part of the ceiling panel 83b constituting the annular conditioned air duct 80, and a part of the conditioned air supplied from the conditioned air duct 80 into the cabin is supplied from the slit 96 into the cabin. Other conditioned air may be supplied from the outlet 87 into the cabin.

With the above configuration, the conditioned air that has flowed into the conditioned air duct 80 flows in the longitudinal direction of the conditioned air duct 80 from the gap between the horizontal end 80ce and the ceiling panel 83b. The air was blown in a substantially horizontal direction toward the central portion of the conditioned air duct 80 so as to intersect the longitudinal direction (the flow direction of the conditioned air), and flowed along the lower surface of the diffusion plate 88 constituting the lighting device 81. After that, it will flow downward.

For this reason, the conditioned air blown out from the blowout port 87 does not directly collide with a passenger seated in a passenger room belonging to the low roof portion B, so passenger comfort is not hindered.
Further, the conditioned air duct 80 is manufactured by combining the C channel-shaped open flow path and the ceiling panel 83b, thereby reducing the height of the gap H2 (see FIG. 4) between the low roof structure 34 and the lower ceiling panel 83b. As a necessary minimum, a large ceiling height dimension H1 of the low roof portion can be secured. For this reason, since the distance between the conditioned air outlet 87 and the passenger increases, the ceiling height can be secured and an open feeling can be obtained. In addition, since the blowing air is directed downward after being blown out along the horizontal direction, it is possible to reduce the discomfort caused by blowing the blowing air directly to the passengers and enhance the comfort.

Further, since the duct is formed by covering one surface of the channel material with the ceiling panel 83b, the number of parts is small compared with the case where the duct independent from the ceiling panel 83b is arranged, and the manufacturing process is small and light. The ceiling module 92 can be manufactured. Furthermore, since the ceiling module 92 including the conditioned air duct may be fixed to the low roof portion B, the ceiling can be constructed with a small number of manufacturing steps.

On the other hand, since the exhaust duct 86 and the conditioned air duct 89 having a large cross-sectional area can be accommodated in the space 91 between the upper end portion 35 and the end inclined surface 34a of the side structure 32, the flow velocity of the exhaust air and the conditioned air flowing through these ducts. Can be lowered. As a result, it is possible to reduce the pressure loss and fluid noise of the ducts and the power consumption of the blower, and to suppress the generation of noise generated from these ducts.

It should be noted that the present invention is not applied only to a railway vehicle having both a high roof portion (general portion) A and a low roof portion B in one vehicle as in this embodiment. Even when applied to a railway vehicle (rail vehicle) including only a roof portion that cannot secure a sufficient ceiling height in relation to the limit, the above-described effects are exhibited.

[Example 2]
7 is a horizontal sectional view (corresponding to FIG. 3) of the high ceiling portion and the low ceiling portion of the second embodiment, and FIG. 8 intersects the longitudinal direction of the end portion in the width direction of the low ceiling portion of the present embodiment. FIG. 8 is a sectional view (HH section in FIG. 7).
Description of matters common to the first embodiment will be omitted, and different configurations will be mainly described.

In this embodiment, the conditioned air duct 90 has one end connected to the connection duct 93 and the other end 90a closed, and has a substantially rectangular side in plan view.
Although the shape of the conditioned air duct 90 in plan view is different from that of the first embodiment, it is configured by combining a C channel member having an open portion and the ceiling panel 83b, and a blast that blows conditioned air in the horizontal direction and supplies it into the cabin. The point having the opening 87 is the same as that of the first embodiment.

In this embodiment, as shown in FIG. 7, two rows of lighting devices 81a are arranged on the ceiling panel 83b outward in the width direction of the conditioned air duct 90 along the longitudinal direction of the conditioned air duct 90 leading vehicle 1a. Is provided.
Since a diffusion plate is not disposed on the side of the blowout port 87 directed inward from the conditioned air duct 90, a rectifying plate 97 that guides the flow 99 of conditioned air is disposed downstream of the blowout port 87 of the conditioned air duct 80.

Similarly to the first embodiment described above, the ceiling module 92 (see FIG. 5) is configured such that the conditioned air duct 80 is formed by fixing the C-channel open channel to the ceiling panel 83b, and the lighting device 81a is installed on the ceiling. It is manufactured by being fixed to the panel 83b. The ceiling module 92 is positioned by being lifted upward from the lower surface of the low roof structure 34, and then fixed to the low roof structure 34 via the support portion 95.

With the above configuration, the conditioned air flowing into the conditioned air duct 80 is blown out in a substantially horizontal direction from the gap between the horizontal end portion 80ce and the ceiling panel 83b in the process of flowing through the annular conditioned air duct 80, and is rectified. After flowing along the plate 97, the flow goes downward. For this reason, the conditioned air blown out from the air outlet 87 does not directly collide with passengers in the cabin belonging to the low roof portion B, and the passenger comfort can be prevented from being hindered.

Furthermore, by producing the conditioned air duct 80 by combining the C channel-shaped open flow path and the ceiling panel 83b, the dimension H2 (see FIG. 4) in the height direction of the ceiling portion of the low roof portion B is reduced. Low roof part ceiling height dimension H1 can be enlarged. For this reason, since the distance between the conditioned air outlet 87 and the passenger can be increased, uncomfortable feeling due to the influence of the blowing air can be reduced and the comfort can be enhanced. Further, since the ceiling module including the conditioned air duct can be fixed to the low roof portion B with a small number of work steps, the manufacturing cost can be reduced.

Although not shown, the end portion 90b provided along the width direction of the leading vehicle 1a of the conditioned air duct 90 is omitted, and after extending in the width direction from the other end portion of the connection duct 93, the direction is changed in the longitudinal direction. A conditioned air duct 90 may be provided that extends in a modified manner. If it is set as this structure, the conditioned air to the cabin of the low roof part B can be supplied by the ceiling panel 83b incorporating the conditioned air duct 90 of a simpler structure.

According to the present invention, in the process in which conditioned air from the air conditioning equipment flows along the longitudinal direction of the air conditioning duct of the ceiling module, it is sufficient that the conditioned air is blown out horizontally from the outlet into the cabin. Regarding the shape, etc., depending on the specifications and form of the railway vehicle. Various selections can be made.
