Description

[Technical field]

[0001] The present invention relates to an intake and exhaust device and a railway vehicle equipped with an intake and exhaust device. [Background technology]

[0002] In railway vehicles, ventilation is performed to improve the air quality inside the vehicle. This is generally done using an in-car ventilation system equipped with a blower, but when a larger volume of ventilation is required than the ventilation system can handle, natural ventilation is achieved by opening some of the vehicle's side windows. Ventilation using these side windows is less expensive than installing additional ventilation systems, and has the advantage of not requiring power for ventilation, as it can utilize the wind generated by the movement of the railway vehicle.

[0003] Patent Document 1 discloses the configuration of a railway vehicle that is equipped with a ventilation function, the presence of the ventilation section is immediately noticeable to passengers, and the ventilation section is provided with windows that can be easily opened and closed even when passengers are half-seated, thereby achieving high ventilation efficiency.

[0004] [Patent Document 1] JP 2015-85908 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the conventional configuration, when unconditioned outside air is blown into a part of the vehicle interior through the side window ventilation, the thermal comfort inside the vehicle deteriorates. Furthermore, the outside air blown into the vehicle interior is mixed with outside air with a high wind speed, and there is a possibility that such outside air will hit passengers directly. In addition to the increased discomfort of passengers due to this draft feeling, there is also the issue that the passenger ride comfort is deteriorated due to the rainwater blown in together with the outside air in rainy weather and the noise caused by the blowing in.

[0006] In view of this, the present invention provides an intake and exhaust device and a railway vehicle equipped with an intake and exhaust device that maintains thermal comfort inside the vehicle, reduces the draft feeling felt by passengers, prevents rainwater from being blown in, and reduces noise when outside air is blown in. [Means for solving the problem]

[0007] The intake and exhaust device and the railway vehicle equipped with the intake and exhaust device of the present invention are equipped with an openable side window and a luggage shelf installed above the side window inside the vehicle, and are formed so as to cover an opening created when the upper part of the side window is opened. Effect of the Invention

[0008] According to the present invention, it is possible to provide an intake and exhaust device and a railway vehicle equipped with an intake and exhaust device that maintain thermal comfort inside the vehicle, reduce the draft feeling felt by passengers, prevent rainwater from being blown in, and reduce noise when outside air is blown in.

[Diagram 5] FIG. 2 is a cross-sectional view of a side window according to one embodiment of the present invention. [Figure 6] FIG. 2 is a cross-sectional view of an embodiment of the present invention with a side window open.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The following description and drawings are examples for explaining the present invention, and appropriate omissions and simplifications have been made for clarity of explanation. The present invention can be implemented in various other forms. Unless otherwise specified, each component may be singular or plural.

[0011] In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the drawings may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings.

[0012] (One embodiment of the present invention and overall configuration) (Figure 1) The railway vehicle 1 is composed of a car body 10 and a bogie 20. The car body 10 has an underframe 12 forming the bottom, and a side structure 16 forming the side. The side structure 16 has side sliding doors 18 for allowing passengers to enter and exit the car, and side windows 30 for admitting light into the car.

[0013] The carbody 10 has multiple underfloor devices mounted below the frame 12, such as a drive unit (not shown) for supplying the power necessary to drive the railway vehicle 1, an air conditioning unit (not shown) for regulating the air inside the carbody 10 to maintain a comfortable air environment for passengers, and an auxiliary power supply unit (not shown) for supplying power to auxiliary equipment such as the air conditioning unit.

[0014] (Figure 2) An interior panel 50 is provided on the inside of the side structure 16. A luggage shelf 40 is provided along the interior panel 50 above the side window 30.

[0015] (Figure 3) The luggage shelf 40 is installed in the upper part of the vehicle interior, abutting against a part of the interior panel 50 near the side window 30, and is composed of a luggage shelf bottom plate 42, a back plate 44, and a luggage shelf side plate 46. The luggage shelf bottom plate 42 is where passenger luggage and the like is placed, and supports the luggage shelf side plate 46. The back plate 44 extends in the height direction from an end of the luggage shelf bottom plate 42. The side window 30 is equipped with an upper handle 32, and when it is desired to open the side window 30, the upper part of the side window 30 is opened by moving the upper handle 32 downward.

[0016] (Figure 4) When the side window 30 is opened, outside air 80 flows into the vehicle through the opening due to the effect of natural convection when the railroad vehicle is stopped, and due to the effect of wind when the railroad vehicle is moving. In addition, in the same way that outside air 80 flows in through the opening of the side window 30, the air inside the vehicle can also be exhausted to the outside of the vehicle through the opening.

[0017] However, the outside air 80 flowing in through the openings of the side windows 30 may give passengers a feeling of draft, and may worsen the riding comfort of passengers when, for example, it is hot and humid or cold outside the vehicle. In particular, in rainy weather, rainwater may flow into the vehicle through the openings of the side windows 30 together with the outside air 80. Furthermore, noise is generated when outside air flows in while the railroad vehicle is running, which also becomes a factor that worsens the riding comfort of passengers.

[0018] (Figure 5) The intake and exhaust device 60 of the present invention includes a bottom plate portion 62 and a side plate 66. The bottom plate portion 62 and the side plate 66 are joined together and are installed so as to be pressed against the interior panel 50 via a first packing 64a. The side plate 66 is fastened to the luggage shelf side plate 46 by a fastening member 68, so that the bottom plate portion 62 and the side plate 66 are fixed to the luggage shelf 40. The bottom plate portion 62 and the side plate 66 may be molded integrally. In this manner, the intake and exhaust device 60 is formed to cover the opening of the side window 30.

[0019] The bottom plate portion 62 has a horizontal portion formed perpendicular to the side window 30, and a rising portion formed rising toward the luggage shelf 40. The rising portion of the bottom plate portion 62 abuts against the lower end portion of the back plate 44 via a second packing 64b. The horizontal portion of the bottom plate portion 62 abuts against the side window 30 via a third packing 64c. Note that the third packing 64c abuts against the side window 30 with enough contact to allow the side window 30 to be opened and closed, so a gap is formed.

[0020] A predetermined closed space is formed by the side window 30, the interior panel 50, the luggage shelf 40, and the bottom plate portion 62. This closed space functions as an intake and exhaust device 60, and becomes a flow path for outside air 80 that moves upward from the opening of the side window 30 along the back plate 44 of the luggage shelf 40 (described later in FIG. 6).

[0021] Between the upper end of the back panel 44 and the interior panel 50, the luggage shelf 40 has a gap through which outside air passes toward passengers inside the vehicle, and the gap has a screen 69. The screen 69 prevents foreign matter such as dust and insects contained in the outside air 80 from entering and reaching the passenger side inside the vehicle when the outside air 80 that flows into the vehicle from the opening of the side window 30 moves through the flow path and out of the flow path through the gap between the upper end of the back panel 44 and the interior panel 50. In addition, the side panel 66 has a drain 67 below, which can drain rainwater and the like contained in the outside air 80 that flows in from the side window 30.

[0022] The side window 30 has an upper handle 32 and a lower handle 34 on the upper and lower sides, respectively. A third packing 64c of the bottom plate portion 62 abuts between the upper handle 32 and the lower handle 34 of the side window 30. The lower handle 34 is provided because the provision of the suction and exhaust device 60 means that the side window 30 can no longer be operated by the upper handle 32 alone as in the conventional case. The lower handle 34 may be fixed to the frame of the side window 30 or to the window glass of the side window.

[0023] (Figure 6) The side window 30 is opened by operating the lower handle 34, and at this time the upper handle 32 of the side window 30 comes into contact with the third packing 64c of the intake and exhaust device 60. This eliminates the gap between the side window 30 and the bottom plate portion 62 that exists when the side window 30 is closed, and prevents outside air 80 containing rain, wind, and foreign objects from causing discomfort to passengers around the luggage rack 40.

[0024] When the railway vehicle runs with the side windows 30 open, part of the wind generated by the running of the vehicle flows into the vehicle interior through the openings of the side windows 30. Outside air 80 that flows into the vehicle interior flows through the flow path of the intake and exhaust device 60 from the bottom plate portion 62 along the back plate 44 toward the upper part of the vehicle interior, passes through the screen 69, and flows into the passenger side of the vehicle interior. This outside air 80 is blown in so as to collide with the side plate 66 while the vehicle is running, but the provision of the first packing 64a makes it possible to prevent the outside air 80 that collides with the side plate 66 from blowing over outside the vehicle, so that the outside air 80 can be reliably moved toward the upper part of the vehicle interior.

[0025] The outside air 80 that passes through the screen 69 flows toward the ceiling along the side ceiling of the vehicle. The outside air 80 merges with conditioned air flowing into the vehicle from the conditioned air outlet of the air conditioner provided on the vehicle ceiling, thereby supplying air to the passengers inside the vehicle. In this way, by using the intake and exhaust device 60, the outside air 80 is supplied from above the luggage rack 40 through the ceiling to the passengers, thereby reducing the feeling of draft for the passengers. In addition, even if the outside of the vehicle is hot and humid or cold, and such outside air 80 enters the vehicle, it merges with the conditioned air from the air conditioner, thereby reducing discomfort for the passengers.

[0026] Furthermore, in rainy weather, when rainwater blows in together with outside air 80 from the openings of the side windows 30, the rainwater temporarily collects in the horizontal portion of the bottom plate portion 62 of the intake and exhaust device 60, and can then be discharged from the drain 67 via a hose (not shown) and a drain hole (not shown) provided in the vehicle body to the outside. Also, while the vehicle is moving, there is a high possibility that noise from outside the vehicle will enter the vehicle through the openings, but since the intake and exhaust device 60 partially blocks out the noise, the sound pressure level of the noise reaching the passengers can be reduced.

[0027] The present invention is not limited to the above-described embodiment, and various modifications and other configurations can be combined without departing from the spirit of the present invention. Furthermore, the present invention is not limited to those having all of the configurations described in the above-described embodiment, and includes those in which some of the configurations are omitted.
