Description

  The present invention relates to a vehicle including an ion generator, and more particularly to a vehicle in which a plurality of seats including positive and negative ion generators and a blower are arranged.

  Passengers exposed to dirty outside air enter and exit various types of vehicles such as railway vehicles and buses. And passengers getting into the vehicle often bring bacteria, pollen, dust, etc. contained in the outside air into the vehicle. Especially on rainy days, shoes and umbrellas of passengers entering the vehicle are brought into the vehicle in a wet state, so that the floor in the vehicle collects fungus, pollen, dust, and rainwater. It becomes a state.

  Fungi, pollen, dust, and the like are minute things that are invisible, and usually move while floating in the air. And fungi, pollen, dust and the like naturally fall with the passage of time, and finally fall to the floor and ground. Therefore, the vicinity of the floor of the vehicle is in a state where there are very many fungi, pollen, dust and the like. Although it depends on the environmental conditions in the vehicle, the bacteria after dropping are easy to propagate, and many bacteria may live on the floor in the vehicle. In particular, since the floor surface in the vehicle is often wet on a rainy day, the floor surface in the vehicle on a rainy day is in a perfect condition for the propagation of bacteria.

  As described above, there are a lot of bacteria, pollen, dust, etc. on the floor surface and in the vicinity of the floor surface in the vehicle, and these may adhere to the passenger getting into the vehicle and possibly adversely affect the passenger. Is very high.

In order to solve these problems, Japanese Patent Laid-Open No. 2006-69427 (Patent Document 1) proposes an ion control vehicle. The ion control vehicle has a plurality of chairs, a positive / negative ion generator that emits ions from the back of one of the plurality of chairs, a rotation axis that changes the orientation of any of the plurality of chairs, and a rotation axis that has been changed. By comparing the orientation of the chair with the orientation sensor that detects the orientation of the chair, the first chair, which is one of a plurality of chairs, is in front of the first chair and the positive / negative ion generator emits ions. To determine whether or not to face the back of the second chair, and to release ions from the back of the second chair if it determines that the first chair faces the back of the second chair In addition, a control unit for controlling the positive / negative ion generator and a traveling unit for traveling are included.

[First Embodiment]
<Overall configuration>
First, the overall configuration of the railway vehicle 10 according to the first embodiment of the vehicle will be described. FIG. 1 is a plan view showing a railway vehicle 10 as an example of a vehicle in which seats 100 are arranged in the traveling direction. Hereinafter, as a first embodiment, a railway vehicle 10 in which seats 100 are arranged in the traveling direction as shown in FIG. 1 will be described. A railway vehicle 10 as shown in FIG. 1 is mainly used for a bullet train, a special express train, and the like, but can be applied to a vehicle in which seats 100 are arranged in a traveling direction such as a bus. As shown in FIG. 1, a plurality of seats 100 for passengers to sit are arranged inside the railway vehicle 10.

  FIG. 2 is a side sectional view showing seats 100A and 100B according to the present embodiment. FIG. 3 is a partial cross-sectional plan view showing seats 100A and 100B according to the present embodiment. 2 and 3, railcar 10 according to the present embodiment is railcar 10 in which a plurality of seats including a first seat 100A and a second seat 100B are arranged. One seat 100A is arranged behind the second seat 100B and adjacent to the second seat 100B. Hereinafter, “seats 100A and 100B” are collectively referred to as “seat 100”.

  Each of the seats 100 includes a positive / negative ion generator 101, a blower 103, a blowout port 104, a suction port 105, a heater 108, and a weight sensor 109 in a lower part 100 a of the seat 100. Each of the seats 100 includes an armrest 102, a control switch 106, and a seat controller 130.

  The lower portion 100a of the seat 100 is provided with a blowout port 104 by forming an opening on the front surface (front surface). The lower portion 100a of the seat 100 is provided with a suction port 105 by forming an opening on the rear surface (rear surface). A lower passage 113 for air and positive / negative ions to flow from the inlet 105 to the outlet 104 is formed in the seat lower part 100a.

Positive and negative ion generators 101 are arranged in the lower passage 113. The positive / negative ion generator 101 has a built-in surface electrode provided on the surface of a flat dielectric such as ceramic (not shown) and an internal electrode embedded in the dielectric (not shown) and provided in parallel with the surface electrode. To do. When an alternating voltage is applied between the two electrodes, oxygen or moisture in the air is ionized (given energy) between the two electrodes to generate positive ions and negative ions. The generated ions are positive ions H ⁺ (H ₂ O) _m (m is “0” or any natural number) and negative ions O ₂ ⁻ (H ₂ O) _n (n is “0”). Or any natural number).

<Disinfection principle>
Here, the principle of sterilization by the positive / negative ion generator 101 will be described more specifically. As described above, positive and negative ions generated in the positive and negative ion generator 101 are sent forward from the lower seat portion 100 a by the blower 103. The positive and negative ions generated by the positive and negative ion generator 101 may be discharged into the space by a fan (not shown) installed in the positive and negative ion generator 101. These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of planktonic bacteria. The attached ions generate H ₂ O ₂ or .OH (".OH" indicates radical OH) by a chemical reaction. Chemical reactions are shown in formulas (1) to (3). In Formula (1)-Formula (3), m, n, p, q is arbitrary natural numbers.

^{_{H + (H 2 O) m}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ... (1)
^{_{H + (H 2 O) m}} + H + (H 2 O) p + O 2 - (H 2 O) n + O 2 - (H 2 O) q → 2 · OH + O 2 + (m + p + n + q) H ₂ O ... (2)
^{_{H + (H 2 O) m}} + H + (H 2 O) p + O 2 - (H 2 O) n + O 2 - (H 2 O) q → H 2 O 2 + O 2 + (m + p + n + q) H ₂ O (3)
When these active species are generated, suspended bacteria and pollen are destroyed by the decomposition of the active species. This effectively inactivates airborne bacteria and pollen in the air. That is, airborne bacteria and pollen in the air are efficiently removed.

Moreover, said Formula (1)-Formula (3) produces the same effect | action also on the hazardous | toxic substance surface in air. Since the same action occurs, hydrogen peroxide (H ₂ O ₂ ) or hydroxyl radical (.OH) which is an active species oxidizes or decomposes harmful substances. This means that chemical substances such as formaldehyde and ammonia are converted into harmless substances such as carbon dioxide, water and nitrogen. Since it is converted into a harmless substance, it is substantially rendered harmless.

  When positive ions and negative ions are sent out from the positive / negative ion generator 101, fungi and fungi in the air are inactivated by the action of these positive ions and negative ions. Since mold and fungi are inactivated, their growth is suppressed. Positive ions and negative ions have a function of inactivating viruses such as Coxsackie virus and poliovirus. Since these viruses are inactivated, contamination due to contamination of these viruses is prevented.

  Positive ions and negative ions also have a function of decomposing molecules that cause odors. Since the odor source molecule is decomposed, it can be used for deodorizing the interior space of the vehicle.

<Overall configuration>
Returning to the description of the overall configuration, the blower 103 is disposed at the rear of the lower passage 113. The blower 103 is realized by, for example, a sirocco fan, and sends positive ions and negative ions generated by the positive / negative ion generator 101 to the front of the seat lower part 100a. As shown in FIGS. 2 and 3, the rear seat (first seat 100 </ b> A) has a rear seat (first seat 100 </ b> A) between the blow-out port 104 and the front seat (second seat 100 </ b> B). It is a foothold for passengers sitting in the seat 100). For this reason, if the amount of air blown from the outlet 104 is too large, the passenger may feel uncomfortable, so the amount of air blown by the blower 103 is set as small as possible. As a result, there is an advantage that positive and negative ions can be drifted in the vicinity of a foothold for passengers for a long time while supplying positive and negative ions.

  An armrest 102 is erected on one side or both sides of the upper portion 100 b of the seat 100. A control switch 106 is provided on the upper surface or side surface of the armrest 102. The passenger can change the amount of positive / negative ions generated by the positive / negative ion generator 101 and the wind speed and amount of air sent by the blower 103 to desired ones by operating the control switch 106. For example, normally (when the switch is OFF), the positive / negative ion generator 101 generates a small amount of positive / negative ions and the blower 103 generates a small amount of air flow. When the control switch 106 is turned on, the positive / negative ions are generated. The generator 101 may generate a large number of positive and negative ions, and the blower 103 may generate a large amount of air flow.

  For example, the passenger's shoes 107 may be wet on a rainy day. In this case, since the environmental conditions near the floor of the scaffolding are favorable conditions for the propagation of the bacteria, there is a possibility that many bacteria live near the floor of the scaffolding. For this reason, it is desirable to quickly remove bacteria near the floor of the foothold. In the present embodiment, it is possible for the passenger to increase the amount of positive and negative ions generated by the control switch 106. In addition, positive and negative ions can be blown toward the shoe 107 with a large air volume so that the bacteria do not propagate on the shoe 107 of the passenger.

  A heater 108 is provided in the lower part 100 a of the seat 100. It is also possible to turn on the heater 108 by the control switch 106 and dry the wet shoes 107.

  A weight sensor 109 is installed in the seat 100, and whether or not a person is sitting on the seat 100 can be determined based on information obtained from the weight sensor 109. And it is also possible to perform ON / OFF control of the positive / negative ion generator 101 installed in the seat lower part 100a. For example, normally (when it is determined that no person is sitting on the seat 100), the positive / negative ion generator 101 generates a small amount of positive and negative ions, and the blower 103 generates a small amount of air flow. When it is determined that a person is sitting on the floor, the positive / negative ion generator 101 may generate a large amount of positive / negative ions, and the blower 103 may generate a large amount of air flow.

  As described above, each seat 100 of the railway vehicle 10 according to the present embodiment sucks air from the back of the seat lower part 100a and sends the air forward, so that positive ions and negative ions are forward of the seat lower part 100a. It blows out.

  In this way, positive and negative ions emitted from the blowout port 104 formed on the front surface of the lower part 100a of the first seat 100A pass through the vicinity of the floor surface between the seats 100A and 100B, and the suction port of the second seat 100B. 105 is reached. In other words, in railway vehicle 10 according to the present embodiment, positive and negative ions emitted from each first seat 100A exist in the vicinity of each floor surface between first seat 100A and second seat 100B. It is the composition to do. In other words, air containing a large amount of positive and negative ions can be continuously supplied to the vicinity of the floor surface between the seats 100A and 100B where bacteria and the like easily propagate, and the sterilization of the railway vehicle 10 can be performed efficiently. it can. Each seat 100 may be a first seat 100A for a seat in front of the seat and a second seat 100B for a seat after the seat.

  Further, in the above description, the suction port 105 is opened on the rear surface of each seat 100 and the blowing port 104 is opened on the front surface. That is, the railway vehicle 10 according to the present embodiment is configured such that air containing positive and negative ions is blown from the rear to the front. However, conversely, the air containing positive and negative ions may be blown from the front to the rear. That is, it is good also as a structure which opens the blower outlet 104 in the rear surface of each seat 100, and opens the suction inlet 105 in the front surface. In this case, each seat 100 may be a second seat 100B for a seat in front of the seat and a first seat 100A for a seat after the seat.

  In the case where the lower part 100a of the seat 100 is fixed with respect to the railcar 10 and the upper part 100b of the seat 100 is rotatable, the first seat 100A and the first seat 100A are rotated by the rotation of the seat 100. The relationship between the second seat 100B and the front-rear direction (traveling direction) of the vehicle is reversed. In the present embodiment, even if the seat 100 rotates, each first seat 100A (second seat 100B) is located near each floor between the first seat 100A and the second seat 100B. The structure has positive and negative ions released from.

  Similarly, in the case of a vehicle in which the lower part 100a of the seat 100 is fixed with respect to the railway vehicle 10 and the tilting direction of the backrest of the seat 100 can be changed, the tilting direction of the seat 100 is changed. The relationship between the first seat 100A and the second seat 100B and the vehicle front-rear direction (traveling direction) is reversed. In the present embodiment, even if the tilting direction of the seat 100 is changed, each first seat 100A (the second seat is located near each floor between the first seat 100A and the second seat 100B. In this configuration, positive and negative ions emitted from the seat 100B) exist.

<Control configuration>
FIG. 4 is a block diagram showing a control configuration of the railway vehicle 10 according to the present embodiment. As shown in FIG. 4, the railway vehicle 10 includes a positive / negative ion generator 101, a blower 103, a seat controller 130, a control switch 106, and a weight sensor 109 for each seat 100.

  The weight sensor 109 is realized by, for example, a load cell or a strain gauge, and measures the weight of an object on the seat 100 and transmits the measurement result to the seat controller 130.

  The seat controller 130 determines whether or not the weight (measurement result) of the object placed on the seat 100 is equal to or greater than a preset threshold value based on the measurement result. The seat controller 130 determines that a passenger is sitting on the seat 100 when the weight of the object is greater than or equal to a preset threshold value, and causes the positive / negative ion generator 101 and the blower 103 to A signal for operating the ion generator 101 and the blower 103 is transmitted.

  Here, the seat controller 130 determines that the passenger is sitting on the seat 100 when the weight of the object is equal to or greater than a preset threshold value, and the positive / negative ion generator 101 performs positive / negative ion generation. May be transmitted, or a signal for increasing the amount sent by the blower 103 may be transmitted. An increase in the amount of positive / negative ions generated by the positive / negative ion generator 101 and an increase in the amount sent by the blower 103 can be easily realized by increasing the voltage applied to them.

  The control switch 106 is a device for receiving a command from a passenger sitting on the seat 100 and transmitting the command to the seat controller 130. The control switch 106 may be composed of a plurality of buttons or a touch panel, and its form is not limited. That is, the seat controller 130 transmits a control signal to the positive / negative ion generator 101 and the blower 103 based on the signal transmitted by the control switch 106.

<Modification of control configuration>
Here, a modified example of the control configuration of the railway vehicle 10 will be described. FIG. 5 is a block diagram showing a modification of the control configuration of the railway vehicle 10 according to the present embodiment. The control configuration shown in FIG. 4 includes a seat controller 130 for each seat 100, and controls the operations of the positive / negative ion generator 101 and the blower 103 for each seat 100 by the seat controller 130.

  In this modified example, as shown in FIG. 5, the railway vehicle 10 has a vehicle controller 11, and the positive and negative ion generators 101 and the blowers 103 of all seats 100 in which the vehicle controller 11 is arranged in the railway vehicle 10. The operation is controlled. As described above, the railway vehicle 10 includes a positive / negative ion generator 101, a blower 103, a control switch 106, and a weight sensor 109 for each seat 100.

  The weight sensor 109 measures the weight of an object on the seat 100 and transmits the measurement result to the vehicle controller 11.

  Based on the measurement result, the vehicle controller 11 determines whether or not the weight (measurement result) of the object placed on the seat 100 is equal to or greater than a preset threshold value. The vehicle controller 11 determines that a passenger is sitting on the seat 100 when the weight of the object is greater than or equal to a preset threshold, and causes the positive / negative ion generator 101 and the blower 103 to A signal for operating the ion generator 101 and the blower 103 is transmitted. Here, the vehicle controller 11 determines that the passenger is sitting on the target seat 100 when the weight of the object is greater than or equal to a preset threshold value, and the target seat 100 A signal for increasing the amount of positive / negative ions generated by the positive / negative ion generator 101 or increasing the amount of sending by the blower 103 of the target seat 100 may be transmitted.

  The control switch 106 is a device for receiving a command from a passenger sitting on the seat 100 and transmitting the command to the vehicle controller 11. The control switch 106 may be composed of a plurality of buttons or a touch panel, and its form is not limited. That is, based on the signal transmitted by the control switch 106, the vehicle controller 11 transmits a control signal to the positive / negative ion generator 101 and the blower 103.

<First modification of seat>
Next, a first modification of seat 110 in railway vehicle 10 according to the present embodiment will be described. FIG. 6 is a partial cross-sectional plan view showing a modification of seat 110 in railcar 10 according to the present embodiment. As shown in FIG. 6, a plurality of seats 110 are installed side by side on both the left and right sides of a central passage 12 located in the center of the railway vehicle 10 inside the railway vehicle 10 according to the present embodiment. . Each seat 110 has a positive / negative ion generator 101, a blower 103, a suction port 105, and a blowout port 114. Since the configuration other than the outlet 114 is the same as that of the first embodiment, the description thereof will not be repeated here.

  The outlet 114 in this modification is opened obliquely forward on the passage side of the seat lower part 110a. Each seat 110 may be formed with a blowout port 104 formed on the front surface of the seat lower portion 110a. Here, the outlets 104 and 114 may be formed as separate outlets, or may be formed integrally. That is, two air outlets 104 and 114 may be formed in the seat 110, or one air outlet 114 may be formed.

  For example, a certain seat 110 (for example, the middle seat 110 in the upper row in FIG. 6) is used as the second seat 110B, and the seat 100 disposed obliquely behind the second seat 110B across the central passage 12 is the first. Seat 110A. In the present modification, positive and negative ions are released from the lower portion 110a of the first seat 110A toward the outlet 104 of the second seat 100B installed obliquely in front of the first seat 110A. It has a configuration. That is, since the first seat 110A according to this modification emits positive and negative ions toward the vicinity of the floor surface obliquely forward of the first seat 110A, it is possible to remove bacteria and the like in a wider range of floor surfaces. In other words, since it is possible to sterilize the vicinity of the floor surface of the central passage 12 through which people frequently pass, that is, a portion where many bacteria or the like are present (bred), the sterilization in the railway vehicle 10 can be performed efficiently. Can do.

  Further, as shown in FIG. 1, when the seats 100 are arranged on the left and right with the central passage 12 in between, the flow of air in one of the left and right rows and the flow of the other air may be reversed. That is, in the left and right rows, the front seat in the traveling direction is the first seat, the rear seat in the traveling direction is the second seat, and the other row is the first seat in the traveling direction. The front seat in the traveling direction is the second seat. By arranging the seat 100 in this way, the overall air flow in the railway vehicle 10 can be made smooth. That is, since air containing a large amount of positive and negative ions circulates smoothly around the floor surface in the railway vehicle 10, sterilization in the railway vehicle 10 can be performed more efficiently.

<Second modification of seat>
Next, a second modification of the seat 120 in the railway vehicle 10 according to the present embodiment will be described. FIG. 7 is a side sectional view showing a modified example of seat 120 in railway vehicle 10 according to the present embodiment. The seat 120 according to the second modification is mainly assumed to be a seat 120 installed in the last row of a vehicle such as a bus or an automobile. In the seat 120 installed in the last row of a vehicle such as a bus or an automobile, it is difficult to form the suction port 105 on the back surface of the seat lower portion 120a. Therefore, a duct 123 is formed in the vertical direction at the rear portion of the seat 120, and a suction port 125 is formed at the upper end portion of the duct 123.

  In this case, positive and negative ions are released from the lower portion 120a of the seat 120 toward the blowout port 104 of the seat 100 (110) installed in front of the seat 120 or diagonally forward on the passage side. As a result, positive and negative ions are released toward the front of the seat 100 and near the floor surface obliquely forward, and bacteria on a wider range of floor surfaces can be removed.

[Second Embodiment]
<Overall configuration>
Next, the whole structure of the rail vehicle 20 which concerns on 2nd Embodiment of a vehicle is demonstrated.
