Description

  The present invention relates to a railway vehicle having a deodorizing / sterilizing function.

  An unspecified number of people ride on railroad vehicles, and handrails, seats, and the like are undesirably hygienic because unspecified people touch and sit one after another. In addition, various odors and allergen substances enter the railway vehicles on which an unspecified number of people ride, and these odors and allergen substances adhere to the vehicle seats, walls, ceilings, floors, etc. It has become. In particular, when there are a large number of passengers, there is a problem that the body odor, sweat odor, makeup odor, odor coming out of luggage, etc. are mixed in the vehicle, thereby deteriorating the in-vehicle environment.

  Conventionally, in a railway vehicle, a punching plate carrying a photocatalyst is provided in a duct of an air conditioner for air-conditioning the air in the vehicle, and the air in the vehicle is sucked into the air-conditioner to be air-conditioned again in the vehicle. Japanese Patent Application Laid-Open No. 2004-133867 discloses a method in which air is sterilized by a photocatalyst when passing through a punching plate carrying a photocatalyst when air in a vehicle is sucked into an air conditioner.

  However, in the conventional example shown in Patent Document 1, among the bacteria floating in the space in the vehicle, only the bacteria present in the intake air sucked into the air conditioner are sterilized by the photocatalyst. However, bacteria that are not inhaled by the air conditioner among the bacteria floating in the vehicle space are not only sterilized, but allergen substances, handrails, seats, etc. floating in the vehicle are unspecified. Bacteria and allergen substances adhering to the parts where people touch and sit one after another, bacteria and allergen substances adhering to the walls, ceilings, floors, etc. in the vehicle, or clothes of people on board There is a problem that bacteria and allergen substances adhering to can not be sterilized.

Conventionally, the air conditioner is provided with a filter to deodorize, but in this case, only the intake air sucked into the air conditioner out of the air in the vehicle is deodorized and sucked into the air conditioner. Not only is the air that has not been removed, but the handrails and seats adhere to odors that are attached to areas where an unspecified person touches or sits one after another, or to walls, ceilings, floors, etc. in the vehicle. However, there is a problem that the odor adhering to the clothes or the clothes of the passengers cannot be deodorized.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 2 shows a schematic configuration diagram of the electrostatic atomizer 4 used in the present invention. In the embodiment shown in FIG. 2, moisture in the air is obtained by the cooling unit 14 of the heat exchanger 13 such as a Peltier unit. Water is supplied to the discharge electrode 1 by cooling the water and generating condensed water. Therefore, in this embodiment, the cooling unit 14 constitutes the water supply means 2 that supplies water to the discharge electrode 1.

  In FIG. 2, an example of a Peltier unit is shown as the heat exchanger 13. In the Peltier unit, a pair of Peltier circuit boards 15 having a circuit formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity are arranged in multiple rows so that the circuits face each other. The thermoelectric element 16 is sandwiched between the two Peltier circuit boards 15 and the adjacent thermoelectric elements 16 are electrically connected to each other by circuits on both sides, to the thermoelectric element 16 from the Peltier power supply 17 formed via the Peltier input lead wire. Is configured such that heat is transferred from one Peltier circuit board 15 side toward the other Peltier circuit board 15 side. In addition, a cooling unit 14 is connected to the outside of the Peltier circuit board 15 on one side, and a heat dissipation unit 18 is connected to the outside of the Peltier circuit board 15 on the other side. Then, an example of a heat radiating fin is shown as the heat radiating portion 18. The rear end of the discharge electrode 1 is connected to the cooling part 14 of the Peltier unit.

  The discharge electrode 1 is surrounded by a cylinder 19 made of an insulating material, and an opening 19 a that communicates the inside and outside of the cylinder 19 is provided on the peripheral wall of the cylinder 19. In addition, the ring-shaped counter electrode 20 is disposed at the tip opening of the cylindrical body 19, and the center of the ring of the ring-shaped counter electrode 20 is positioned on the extension line of the axis of the discharge electrode 1.

  When a high voltage is applied between the discharge electrode 1 and the counter electrode 20 in a state where water is supplied to the discharge electrode 1 in this way, the discharge electrode is caused by the high voltage applied between the discharge electrode 1 and the counter electrode 20. The Coulomb force acts between the water supplied to the tip of 1 and the counter electrode 20, and the liquid level of water locally rises in a cone shape (tailor cone). When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). Receiving and repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension, a large amount of nanometer-sized charged fine particle water containing active species is generated and discharged (in FIG. 2, the tip opening of the cylinder 19 is used as the discharge opening).
