Description

  The present invention relates to a railway vehicle including an ion generator.

  In a railcar, an unspecified number of people get on, so the air in the passenger compartment of the vehicle tends to get dirty. In particular, in a high-speed railway vehicle, since the distance between stations is long and the passenger compartment of the vehicle is separated from the entrance, natural ventilation is not easily performed in the passenger compartment of the vehicle. In high-speed rail cars, air conditioning units are used for both cooling and heating, and cabin air conditioning is performed by operating the air conditioning unit to perform air conditioning in the vehicle, but the cabin air is sufficiently cleaned. It ’s hard to say.

  Therefore, a configuration has been proposed in which an ion generator is disposed in the vicinity of an air conditioner in order to improve the in-vehicle environment (for example, see Patent Document 1). In Patent Document 1, an air-conditioning outlet is provided on the ceiling board, and an ion generator is attached to the lower surface of the ceiling board on the side of the air-conditioning outlet. According to this, the airflow blown out with the ions from the air outlet of the ion generator intersects or is close to the airflow blown out from the air-conditioning outlet, so that the air containing the ions is distributed to the passenger compartment of the vehicle. .

JP 2011-238581 A

  However, in a conventional railway vehicle such as a commuter vehicle, the air conditioner has only a cooling function, and a heater device is provided as a heater under the seat. As described above, since the operation period of the air conditioner is limited to the summer season, even if the ion generator is provided near the air conditioning outlet of the air conditioner, the period during which the function of the ion generator is exhibited is the summer season. There was a problem that it was limited to.

  Therefore, an object of the present invention is to provide a suitable configuration that makes it possible to improve the cabin environment of a vehicle regardless of the timing when the air conditioner is operated.

  A railway vehicle according to an embodiment of the present invention includes a roof plate, a ceiling plate disposed below the roof plate and having openings formed therein, and a fan arrangement space that protrudes upward from left and right ends of the openings. A vehicle body having a pair of partition plates forming a fan, a blower frame, a line flow fan supported by the blower frame in a state of being arranged in a direction extending in the front-rear direction, and generating a flow of air, and the line flow fan And a fan casing that is supported by the blower frame in a state in which the air is stored and that blows out the air toward the passenger compartment of the vehicle body through the opening, and is disposed in the blower arrangement space. And an ion generator that generates ions to be sent to the cabin through the opening together with the air that is disposed in the blower arrangement space and discharged from the blower opening The blower frame includes a frame main body portion that supports the line flow fan and the fan casing, and a flange that partially protrudes in a left-right direction from a part of the frame main body portion and is detachably attached to the vehicle body. The ion generator is positioned between the partition plate and the air outlet below the flange portion, and overlaps at least a part of the flange portion in a left-right direction position, and It is located on either side of the flange in the front-rear direction.

  According to the above configuration, since the ions from the ion generator are efficiently sent out to the passenger compartment of the vehicle on the flow of air discharged from a blower that is generally longer in operation period than the air conditioner, the air conditioner is operated. Regardless of the time of day, the cabin environment of the vehicle can be improved. Further, when the blower arranged in the blower arrangement space of the vehicle body is removed downward through the opening for maintenance, the ion generator does not interfere with the flange portion moving downward, and the ion generator is not in the blower. Does not interfere with removal. Therefore, it is possible to easily remove the blower while arranging the ion generating device near the blower opening in the blower arrangement space.

  According to the present invention, it is possible to improve the cabin environment of the vehicle regardless of the time when the air conditioner is operated, and to remove the blower while arranging the ion generating device near the blower opening in the blower arrangement space. Can be easily.

  Hereinafter, embodiments will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same or corresponding element through all the figures, and the detailed description which overlaps is abbreviate | omitted.

  FIG. 1 is a schematic cross-sectional view showing a configuration of a railway vehicle 1 according to the embodiment. Hereinafter, for the sake of convenience, the direction of the railway vehicle 1 will be described with the left side of FIG. 1 as “left”, the right side of the page as “right”, the front side of the page as “front”, and the back side of the page as “rear”. That is, the front-rear direction is the vehicle longitudinal direction, and the left-right direction is the vehicle width direction. Further, the upper side in FIG. 1 is “upper” and the lower side in FIG. 1 is “lower”.

  As shown in FIG. 1, the railway vehicle 1 includes a vehicle body 2 having a cabin S in which passengers board and a carriage 9 that supports the vehicle body 2. The vehicle body 2 includes a floor structure 3 which is a bottom of the vehicle body, side structures 4 and 5 whose lower ends are connected to the left and right ends of the floor structure 3, and a roof structure 6 which is connected to the upper ends of the side structures 4 and 5. Have The roof structure 6 includes a roof plate 21 made of corrugated plates and a rafter 27 connected to the lower surface of the roof plate 21. Below the roof plate 21, a ceiling plate 22 having a ceiling surface that partitions the cabin S is disposed. A space between the roof plate 21 and the ceiling plate 22 is provided with a fan arrangement space 50 partitioned by a pair of left and right partition plates 23 and a pair of air conditioning ducts 8 positioned on the left and right outside the fan arrangement space 50. It has been. Cold air from an air conditioner (not shown) flows through the air conditioning duct 8, and the cold air is sent from the lower end opening of the air conditioning duct 8 toward the cabin S. The air conditioner is mounted on the roof structure 6, for example. The air conditioner sucks air from the cabin S, cools the sucked air by heat exchange, and supplies the cooled air (cold air) to the air conditioning duct 8. The blower 7 and the ion generator 10 are arranged in the blower arrangement space 50.

  FIG. 2 is an enlarged cross-sectional view of the blower 7 of FIG. 1 and the vicinity thereof. As shown in FIG. 2, an opening 22 a is formed at the center of the ceiling plate 22 in the left-right direction. The blower arrangement space 50 communicates with the cabin S via the opening 22a. A pair of partition plates 23 protrude upward from the left and right ends of the opening 22a. The pair of partition plates 23 includes a vertical plate portion 23a that extends in the vertical direction and a horizontal plate portion 23b that protrudes from the upper end of the vertical plate portion 23a toward each other. The horizontal plate portion 23b of the pair of partition plates 23 is coupled to the bracket portion 27a of the roof structure 6 via a coupler 25 (for example, a bolt and a nut). A blower mounting frame 24 for mounting the blower 7 is fastened and fixed to the horizontal plate portion 23 b of the pair of partition plates 23 by a coupler 25.

  An air conditioning plate 26 that adjusts the flow of air discharged from the blower 7 is disposed in the opening 22 a of the ceiling plate 22. The air conditioning plate 26 has a plurality of louvers 26a. The air conditioning plate 26 is detachably attached to the ceiling plate 22 so that the air conditioning plate 26 can be removed during maintenance of the blower 7 or cleaning work of the air conditioning plate 26. Specifically, one end portion of the air conditioning plate 26 is rotatably attached to one end portion in the left-right direction of the opening 22 a of the ceiling plate 22 by a hinge 26 b, and the other end portion of the air conditioning plate 26 is attached to the ceiling plate 22. It fixes to the other end part of the left-right direction of the opening part 22a with the coupling tool 28 (for example, screw).

  The blower 7 is disposed in the blower arrangement space 50. A plurality of blowers 7 are installed in the railway vehicle 1 at a predetermined interval in the front-rear direction. When the air conditioner is in operation, the blower 7 serves as an auxiliary to the cooling function and enhances the cooling effect by distributing the cold air uniformly to the cabin S. On the other hand, the blower 7 blows air to the cabin S even when the air conditioner is not in operation. Therefore, the operation period of the blower 7 is longer than that of the air conditioner.

  The blower 7 includes a blower frame 70, a line flow fan 71, a fan casing 72, and an electric motor 73. The blower frame 70 is disposed at the center of the blower arrangement space 50 in the left-right direction, and extends in the front-rear direction. The blower frame 70 includes a frame main body 70 a that supports the line flow fan 71 and the fan casing 72. The frame main body 70a has an inverted U-shaped cross section and has a hollow space that is open at the bottom. The blower frame 70 has a flange portion 70b that partially protrudes outward in the left-right direction from the left and right lower ends of the frame main body portion 70a. The flange portion 70b is detachably attached to the partition plate 23 with bolts 13 (connectors) via the blower mounting frame 24. As will be described later, the blower 7 is detached from the vehicle body 2 by removing the bolt 13 and releasing the connection between the flange portion 70b and the blower mounting frame 24 during maintenance or the like. The blower frame 70 has a protrusion 70c that partially protrudes outward in the left-right direction from the upper end of the frame body 70a. The protruding length of the protruding portion 70c from the frame main body portion 70a is shorter than the protruding length of the flange portion 70b.

  Inside the blower frame 70, a line flow fan 71 that generates an air flow is arranged in a direction extending in the front-rear direction. The line flow fan 71 is driven by an electric motor 73 (see FIG. 3) and rotates. The line flow fan 71 is housed in a substantially cylindrical fan casing 72 in which a blower port 72a extending in the front-rear direction is formed at the lower end. The fan casing 72 is reciprocally rotated coaxially with the line flow fan 71 by an electric motor 73 (see FIG. 3), so that the air blowing port 72a swings in the left-right direction. Therefore, the air generated by the rotation of the line flow fan 71 is discharged over a wide range of the cabin S through the opening 22a in which the air conditioning plate 26 is provided.

  The ion generator 10 is attached to the partition plate 23 via a movable fixing mechanism 11. The ion generator 10 is disposed between the partition plate 23 and the air outlet 72a below the flange portion 70b, and is disposed so as to overlap with a part of the flange portion 70b at the left-right direction position, that is, the ions. The generator 10 is disposed near the blower opening 72a of the blower 7. The ion generator 10 has an electrode inside, and generates positive ions and negative ions by applying a high voltage to water vapor in the air. The ion generator 10 does not have a blowing function. Ions generated from the ion generator 10 naturally flow out from the ion outlet 10a, and are supplied to the cabin S through the opening 22a together with the air discharged downward from the line flow fan 71 through the blower port 72a. The air containing ions suppresses the action and smell of bacteria floating in the cabin S.

  FIG. 3 is a plan view of the blower 7 of FIG. 1 and the vicinity thereof. As shown in FIG. 3, a pair of line flow fans 71 are provided on both sides of the electric motor 73 in the front-rear direction. The electric motor 73 has a drive shaft extending in the front-rear direction, and one end of a pair of line flow fans 71 is connected to both ends of the drive shaft. The other end of the line flow fan 71 is rotatably supported by a frame body 70a of the blower frame 70 via a bearing (not shown). The line flow fan 71 rotates at a constant speed by the driving force of the electric motor 73. One end of the fan casing 72 is connected to the electric motor 73. The electric motor 73 has a speed reduction mechanism (not shown) that reduces the rotational speed and transmits a driving force to the fan casing 72, and a driving force that is transmitted to the fan casing 72 when the fan casing 72 reaches a predetermined rotation angle. And a switching device (not shown) for reversing the rotation direction of the motor. The fan casing 72 is rotatably supported by the frame body 70a of the blower frame 70 together with the other end of the line flow fan 71 via a bearing (not shown).

  The flange portion 70 b of the blower frame 70 partially protrudes outward in the left-right direction from the lower end portion of the frame main body portion 70 a at a position corresponding to the center portion in the front-rear direction of the line flow fan 71. The protruding portion 70 c of the blower frame 70 partially protrudes outward in the left-right direction from the upper end portion of the frame main body portion 70 a at a position corresponding to the center portion in the front-rear direction of the line flow fan 71. The width in the front-rear direction of the protruding portion 70c is smaller than the width in the front-rear direction of the flange portion 70b. The ion generator 10 is disposed at a distance in the front-rear direction from the flange part 70 b on one side in the front-rear direction of the flange part 70 b of the blower frame 70. The ion generator 10 is disposed between the end portion of the line flow fan 71 and the flange portion 70b at the position in the front-rear direction.

  The ion generator 10 is disposed on the side opposite to the electric motor 73 as viewed from the flange portion 70b. The electric motor 73 has a power plug 73 a coupled to a power outlet (not shown) provided in the vehicle body 2. The power plug 73a overlaps the line flow fan 71 at the position in the front-rear direction, and is disposed on the electric motor 73 side as viewed from the flange portion 70b. The power plug 73a is disposed between the frame body 70a and the partition plate 23 in plan view. That is, the ion generator 10 is disposed on the opposite side to the power plug 73a when viewed from the flange portion 70b in plan view.

  FIG. 4 is a perspective view showing the blower frame 70 and the blower mounting frame 24 of FIG. 2 as seen from the left front. 2 and 4, the blower mounting frame 24 includes a vertical plate portion 24a, and a first horizontal plate portion 24b that protrudes from the upper end of the vertical plate portion 24a toward the frame body 70a side (vehicle width direction center side). The second horizontal plate portion 24c protruding from the portion between the upper end and the lower end of the vertical plate portion 24a to the frame main body portion 70a side (vehicle width direction center side), and the frame main body portion 70a side from the lower end of the vertical plate portion 24a ( And a third horizontal plate portion 24d protruding in the vehicle width direction center side). The first to third horizontal plate portions 24a to 24c are located on the outer side in the vehicle width direction than the frame main body portion 70a.

  The first horizontal plate portion 24 b is positioned above the upper surface of the projecting portion 70 c of the blower frame 70, and is fixed to the bracket portion 27 a together with the horizontal plate portion 23 b of the partition plate 23 by the coupler 25. The second horizontal plate portion 24c has a nut 14 fixed to the upper surface thereof, and is positioned below the upper surface of the frame main body portion 70a. The third horizontal plate portion 24d is located below the protruding portion 70c and above the upper surface of the flange portion 70b. The length of the second horizontal plate portion 24c in the left-right direction is shorter than the length of the third horizontal plate portion 24d in the left-right direction. The second horizontal plate portion 24c is separated from the protruding portion 70c in the left-right direction, and the third horizontal plate portion 24d overlaps the protruding portion 70c in plan view. The third horizontal plate portion 24d overlaps the flange portion 70b and the protruding portion 70c in the front-rear direction.

  The anti-vibration rubber 12 is inserted between the second horizontal plate portion 24c and the third horizontal plate portion 24d, and between the third horizontal plate portion 24d and the flange portion 70b. The blower frame 70 is fixed to the blower mounting frame 24 of the vehicle body 2 by inserting the bolt 13 from the lower surface side of the flange portion 70b and fixing the nut 14 to the bolt 13 on the upper surface of the second horizontal plate portion 24c.

  Fig.5 (a) is a front view of the fixing mechanism 11 of FIG. FIG. 5B is a side view of the fixing mechanism 11 of FIG. FIG.5 (c) is a top view of the fixing mechanism 11 of FIG. FIG. 6 is a cross-sectional view illustrating a state in which the ion generator 10 is fixed to the fixing mechanism 11 of FIGS. As shown in FIGS. 5A to 5C and FIG. 6, the fixing mechanism 11 is connected to the partition plate 23 of the vehicle body 2 by screws 30. As with the ion generator 10, a plurality of fixing mechanisms 11 are provided in the left-right direction with the air blowing port 72a interposed therebetween. The fixing mechanism 11 includes a first attachment metal 31, a second attachment metal 32, and a fastening member 33 (for example, a screw or a bolt). The first attachment metal 31 includes a vertical plate portion 31a that is fixed to the partition plate 23 with screws 30, and a guide portion 31d that protrudes from the lower end of the vertical plate portion 31a toward the air blowing port 72a. The guide portion 31d has a horizontal plate portion 31b connected to the vertical plate portion 31a and a pair of side plate portions 31c protruding upward from both front and rear direction ends of the horizontal plate portion 31b. A slit hole 31e extending in the left-right direction is formed at the center in the front-rear direction of the horizontal flat plate portion 31b.

  The second attachment metal 32 is a plate-like slide part 32a that is slidably overlapped with the guide part 31d of the first attachment metal 31 from above, and a plate shape that protrudes upward from the end of the slide part 32a on the air outlet 72a side. Fixed portion 32b. The slide portion 32a is formed with a circular hole 32c that matches a part of the slit hole 31e of the guide portion 31d in plan view. That is, the fastening member 33 is inserted through the slit hole 31e and the circular hole 32c, and the first attachment metal 31 and the second attachment metal 32 are connected. When the slide portion 32a moves in the left-right direction along the guide portion 31d, the circular hole 32c moves in the left-right direction while maintaining a state of communicating with the slit hole 31e. Therefore, the second attachment metal 32 can be connected to the first attachment metal 31 by the fastening member 33 at a plurality of positions where the positions of the slide part 32a with respect to the guide part 31d are different. That is, the fixing mechanism 11 moves the fixing portion 32b in the left-right direction by changing the relative position in the left-right direction between the slide portion 32a and the guide portion 31d. Thus, the slide part 32a and the guide part 31d serve as a movable part of the fixing mechanism 11. In addition, the fastening member 33 exists in the position exposed toward the passenger room S through the opening part 22a in the state which removed the wind regulation board 26. FIG.

  The fixing portion 32b fixes the mounting opening 32d into which the ion generating device 10 is inserted and the bracket portion 10b of the ion generating device 10 to both sides in the front-rear direction of the mounting opening 32d with a coupler 34 (for example, a screw or a bolt). There is a mounting hole 32e. The bracket part 10b of the ion generator 10 is overlapped with the surface of the fixing part 32b on the air blowing port 72a (see FIG. 2) side and fixed by the coupler 34. The fixed portion 32b is inclined at a predetermined angle (for example, 2 to 10 °) with respect to the vertical line in such a direction that the upper end of the fixing portion 32b falls toward the air blowing port 72a (see FIG. 2). Thereby, the ion outlet 10a of the ion generator 10 fixed to the fixing | fixed part 32b is also orient | assigned to the direction which inclined below only the predetermined angle with respect to the horizon.

  In a state where the second attachment metal 32 is closest to the air outlet 72a (the solid line in FIG. 6) in the movable range of the second attachment metal 32 with respect to the first attachment metal 31, the ion generator 10 has the blower frame 70 in plan view. (See FIGS. 2 and 3). On the other hand, in a state where the second attachment metal 32 is farthest from the blower opening 72a in the movable range of the second attachment metal 32 with respect to the first attachment metal 31 (two-dot chain line in FIG. 6), the ion generator 10 is viewed in plan view. In FIG. 3, the frame body portion 70a of the blower frame 70 does not overlap. When the blower 7 and the ion generator 10 are operated, the fixing mechanism 11 is placed in a state in which the second attachment metal 32 is closest to the air outlet 72a, and the ion outlet 10a of the ion generator 10 is brought closer to the air outlet 72a.

  Next, the work of removing the blower 7 during maintenance will be described with reference to FIGS. When an operator removes the blower 7 from the vehicle body 2 for maintenance or the like, first, the coupling tool 28 is removed, and the hinge 26b is also removed by a sliding operation in the front-rear direction, so that the air conditioning plate 26 is removed from the ceiling plate 22. Thereafter, the fastening member 33 is loosened, the second attachment metal 32 is slid to the position farthest from the air blowing port 72a, and the fastening member 33 is fastened again. As a result, the ion generator 10 is retracted to a position that does not overlap the frame body 70a in plan view.

  Thereafter, the bolt 13 for fixing the blower frame 70 and the blower mounting frame 24 is removed, and the blower 7 is moved downward. When the blower 7 moves downward by a certain distance, the protrusion 70c of the blower frame 70 interferes with the upper surface of the third horizontal plate portion 24d of the blower mounting frame 24, and the downward movement of the blower 7 is prevented. Therefore, even if an operator removes the hand from the blower 7 when removing the bolt 13, the blower 7 is prevented from falling. After the projecting portion 70c comes into contact with the upper surface of the third horizontal plate portion 24d, the operator releases the locking by the projecting portion 70c and the second horizontal plate portion 24c. The blower frame 70 is slid forward or backward until it does not overlap the portion 24d (arrow shown in FIG. 4). At this time, the movement range A of the flange portion 70b necessary for releasing the locking by the protruding portion 70c and the second horizontal plate portion 24c is indicated by a two-dot chain line in FIG.

  The ion generator 10 is disposed at a position away from the movement range A in the front-rear direction. When the flange part 70b is slid in the movement range A, the fall prevention by the protrusion part 70c and the 2nd horizontal board part 24c is cancelled | released, and it becomes possible to move the air blower 7 further below. When the blower 7 is moved downward through the opening 22a, the ion generator 10 has already been retracted outward in the left-right direction and is sufficiently separated from the moving path of the blower 7. Does not interfere with the ion generator 10. By doing in this way, without removing the ion generator 10, the blower 7 can be taken out to the cabin S side through the opening 22a, and the blower 7 can be maintained. In addition, when attaching the already-maintained blower 7 to the vehicle body 2, a procedure reverse to the above-described removal work may be performed.

  According to the configuration described above, since the ions from the ion generator 10 are efficiently sent out to the passenger compartment S of the vehicle on the flow of air discharged from the blower 7 whose operation period is longer than that of the air conditioner, the air conditioner Regardless of when the vehicle is driven, the cabin environment of the vehicle can be improved. Further, when the blower 7 arranged in the blower arrangement space 50 of the vehicle body 2 is removed downward for maintenance through the opening 22a, the ion generator 10 does not interfere with the flange portion 70b moving downward, The ion generator 10 does not interfere with the removal of the blower 7. Therefore, it is possible to easily remove the blower 7 while placing the ion generator 10 near the blower opening 72a in the blower arrangement space 50.

  Moreover, since the ion generator 10 is arrange | positioned on the opposite side to the electric motor 73 with respect to the flange part 70b in the front-back direction, the ion generator 10 is not arrange | positioned around the electric motor 73, but the ion generator 10 is an electric motor. It does not hinder work such as wiring 73 and plugging / unplugging of the power plug 73a. Moreover, since the fixing mechanism 11 enables the ion generating device to move in a direction away from the moving path when the blower 7 is detached from the vehicle body 2, the blower can be removed without removing the ion generating device 10 during maintenance. The workability at the time of removing 7 from the vehicle body 2 can be improved.

  Moreover, since the ion generator 10 is fixed to the partition plate 23 in a state of being separated upward from the air conditioning plate 26, the ion generating device 10 does not get in the way when the air conditioning plate 26 is cleaned during maintenance. Therefore, compared with the structure which provides the ion generator 10 in the wind regulation board 26, a maintenance operation becomes easy. Moreover, since a pair of ion generator 10 is arrange | positioned on both sides of the ventilation opening 72a in the left-right direction, ion can be widely sent out to the passenger compartment S of the vehicle by one air blower 7, and the passenger compartment environment of the vehicle is more improved. Can be improved.

  In addition, since the ion generator 10 is installed with the ion outlet 10a tilted downward by a predetermined angle with respect to the horizontal line, the ions are placed on the flow of air discharged downward from the blower 7 into the passenger compartment S of the vehicle. Can be sent out effectively.

  The present invention is not limited to the above-described embodiment, and the configuration can be changed, added, or deleted without departing from the spirit of the present invention. The shape and configuration of the blower 7 are not limited to the shape and configuration described in the above embodiment. For example, in the above-described embodiment, two line flow fans 71 are attached to the electric motor 73 having both axes. However, the present invention is not limited to this, and the line flow fan 71 is arranged in the single-axis electric motor 73. Also good. In the above-described embodiment, the protrusion 70c is provided on the blower frame 70, but the protrusion 70c may not be provided.

  The railway vehicle according to the present invention can improve the cabin environment of the vehicle regardless of when the air conditioner is operated, and can easily remove the blower while disposing the ion generator near the blower opening. It has excellent effects and can be widely used for railway vehicles that can demonstrate the significance of these effects.
