  As disclosed in the above-described invention, by providing the vehicle with an ion generating device, it is possible to sterilize airborne bacteria and the like present in the vehicle. By the way, airborne bacteria and the like present in the vehicle are mainly brought in when an unspecified number of passengers get on the vehicle. In order to sterilize the airborne bacteria efficiently, a high concentration is used by an ion generator. Must be generated in the vehicle. On the other hand, in order to generate high-concentration ions, it is necessary to increase the air volume for releasing the ions. For this reason, if the fan speed is increased, the fan operation noise will increase, and passengers will be required in a quiet vehicle. Will be uncomfortable. This is especially true for vehicles with high confidentiality and quietness such as Shinkansen and express trains.

  However, when the fan rotates to such an extent that it does not cause discomfort to the passengers even when the vehicle is quiet, such as when the vehicle is running in a steady state, the concentration of ions generated in the vehicle increases the rotation of the fan. Compared with the case where it was made to become low. Therefore, there is a problem that sterilization with ions cannot be performed efficiently when a large number of airborne bacteria are brought in as passengers get on and off.

  The present invention has been made to solve the above-described problems, and does not give passengers discomfort due to fan operation noise, and efficiently sterilizes floating bacteria and the like brought in when passengers get on and off. The ion generator which can be used, and a vehicle using the same are provided.

  In order to achieve the above object, the present invention provides an ion generating device that is mounted on a vehicle and includes an ion generating unit that generates ions, a fan for discharging ions generated by the ion generating unit, and air. The sound detection system includes a suction port for sucking in, a blow-out port for blowing ions generated in the ion generation unit into the vehicle in at least one blowing direction, a control means for controlling the fan, and a sound detection device. When sound is detected by the apparatus, the fan is controlled so that the rotational speed of the fan increases for a predetermined time after detection.

  Further, the present invention is an ion generation device including an ion generation unit that is installed in a vehicle and generates ions, a fan for discharging ions generated in the ion generation unit, and a suction port for sucking air in the vehicle And an air outlet that blows out ions generated by the ion generator in the at least one blowing direction into the vehicle, a control means for controlling the fan, and a sound detection device. When the fan is detected, the fan rotates in a direction opposite to the normal direction for a predetermined time after the detection, sucks air in the vehicle from the blowout port, and ions generated in the ion generation unit from the suction port into the vehicle. The fan is controlled so as to blow out.

  Further, the present invention is characterized in that the detection of the sound by the sound detection device is performed by determining whether or not the sound is a specific sound by recognizing the sound.

  According to the present invention, a vehicle includes the ion generator.

  The present invention also includes a first seat disposed on the right side of the vehicle traveling direction, a second seat disposed beside the first seat across the passage, and an upper portion of the first seat. A first luggage shelf, and a second luggage shelf disposed above the second seat, wherein the ion generator is recessed in the ceiling of the vehicle, and all blowing directions from the outlet Is directed in any direction between the first luggage rack and the second luggage rack.

  The present invention also includes a first seat disposed on the right side of the vehicle traveling direction, a second seat disposed beside the first seat across the passage, and an upper portion of the first seat. A first luggage shelf and a second luggage shelf disposed above the second seat, wherein the ion generator is at least one of the first luggage shelf and the second luggage shelf. All the blowing directions from the said blower outlet are facing the direction between the 1st luggage rack and the 2nd luggage rack, It is characterized by the above-mentioned.

The present invention also includes a first seat disposed on the right side of the vehicle traveling direction, a second seat disposed beside the first seat across the passage, and an upper portion of the first seat. A first luggage shelf, and a second luggage shelf disposed above the second seat,
The ion generator is recessed in the ceiling of the vehicle, and when the fan rotates in a direction opposite to the normal direction, ions are blown out from the suction port toward the passage.

  Further, according to the present invention, when the fan is in a normal operation state and rotates in the forward direction, the blowing direction of at least one ion from the blowout port is set on the first luggage rack and the second luggage shelf. It is characterized by facing in at least one direction from the top of the luggage rack.

In the present invention, the ion generating unit may be configured to generate positive ions composed of H ⁺ (H ₂ O) m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) n (n is 0 or an arbitrary natural number). It is characterized by mainly generating negative ions.

  According to the first aspect of the invention, the ion generator is controlled by predicting in advance that the vehicle has arrived at the station and the passenger will move for getting on and off by detecting the announcement in the vehicle by the voice detection device. It is possible to efficiently sterilize or inactivate airborne bacteria, airborne viruses, and the like that are brought into the vehicle by passengers getting on and off, or that have risen as passengers move.

  In general, in-car announcements on the Shinkansen, limited express trains, etc., are mainly made intermittently from several minutes before the vehicle stops at the station until it leaves the station. When the in-vehicle announcement is detected by a voice detection device and the rotational speed of the fan of the ion generator is increased, the amount of ions blown into the vehicle also increases, and the ion concentration in the vehicle before the passenger gets on and off. Becomes higher. Therefore, floating bacteria and the like that increase by being brought into the vehicle when passengers get on and off can be efficiently sterilized or inactivated by high-concentration ions.

  Further, since the rotation speed of the fan is increased when an in-car announcement is made, it is difficult for the passenger to notice the change in the operating sound of the fan even in a quiet space of a vehicle such as a bullet train or a limited express train. Furthermore, before and after stopping at the station, various sounds are generated due to movement of people, etc., so the fan operation sound is not noticeable, and even if the fan rotation speed increases and the operation sound increases, passengers feel uncomfortable. Little to give.

  Furthermore, since the ion generator is controlled by detecting the sound of the announcement in the vehicle, when the ion generator is attached to the vehicle, it is sufficient to connect only the power source, and it is necessary to separately connect a signal line and the like for control. Since there is no, installation becomes easy.

  According to the second aspect of the present invention, when there is little movement of passengers in the vehicle, ions can be blown out from the outlet of the ion generator toward the entire vehicle. In addition, when an in-car announcement is detected, the fan is rotated in the opposite direction, and the air outlet and the suction port are switched to concentrate ions around the passage through which the passenger gets on and off, and the passenger gets on and off. Floating bacteria that have been brought into the vehicle by getting on and off the passenger or moved by moving the passenger by increasing the ion concentration around the passage in advance and blowing out the ions directly toward the passenger through the passage In addition, airborne viruses can be sterilized or inactivated efficiently.

  According to the invention of claim 3, only the voice that means that the vehicle stops or the voice that means that the vehicle departs is detected by recognizing the contents of the in-car announcement detected by the voice detection device. However, it is possible to prevent detection of other in-car announcements.

  According to the invention concerning Claim 4, the vehicle provided with the above-mentioned ion generator can be provided.

  According to the invention of claim 5, ions blown out from the ion generator recessed in the ceiling of the vehicle are efficiently diffused throughout the vehicle without being blocked by the luggage rack installed at the upper part of the seat. can do.

  In addition, in a vehicle or the like, a speaker that usually makes an in-car announcement is often even installed near the ceiling. For this reason, installing an ion generator on the ceiling makes it easier to detect in-car announcements from nearby speakers. On the other hand, since the distance from a passenger becomes far and it becomes difficult to detect the voice and sound which a passenger utters, only the announcement in a vehicle can be detected reliably.

  According to the invention of claim 6, even in a vehicle in which an ion generator cannot be installed on the ceiling due to lighting etc. on the ceiling, ions are poured down into the entire interior of the vehicle by the ion generator, and ions are efficiently injected into the entire vehicle. Can diffuse.

  According to the seventh aspect of the present invention, when there is little movement of passengers in the vehicle, ions can be blown out from the outlet of the ion generator toward the entire vehicle. In addition, when an in-car announcement is detected, the fan is rotated in the reverse direction, and the air outlet and the suction port are switched, so that the ions are concentrated around the passage where the passenger gets on and off, and the passenger gets on and off. Floating bacteria that have been brought into the vehicle by getting on and off the passenger or moved by moving the passenger by increasing the ion concentration around the passage in advance and blowing out the ions directly toward the passenger through the passage In addition, airborne viruses can be sterilized or inactivated efficiently.

  According to the eighth aspect of the present invention, when there is little movement of passengers in the vehicle, ions are diffused throughout the vehicle, and at the same time, bacteria attached to the passenger's luggage placed on the luggage rack are efficiently sterilized. Can do.

  According to the ninth aspect of the present invention, it is possible to efficiently sterilize or inact planate bacteria.

And a front panel 10 as an air guide plate attached to the upper surface (front surface) of the suction grill 20.

  The front panel 10 of the ion generating apparatus 100 is provided with an air suction port 15 in the center, and is on the same plane as the air suction port 15 for discharging ions so as to surround the air suction port 15. Air outlets 11, 12, 13, and 14 are provided as discharge portions. Here, as exemplified in the present embodiment, the same surface is not only when the air suction port and the air outlet are on the same plane, but also when they are on the same bent surface (for example, the air suction port When the normal direction of the opening surface and the normal direction of the opening surface of the air outlet are inclined with respect to each other so as to form an acute angle), when the planes are parallel to each other (for example, air suction In the case where the opening surface of the mouth and the opening surface of the air outlet are provided with a step). The air outlets 11 to 14 are disposed at substantially four corners of the rectangle surrounding the air inlet 15. In the present embodiment, an air outlet is used as an example of an emission part that emits ions. However, the emission part is not limited to this and may have a structure that can emit ions. For example, it is not limited to one that blows out with air, but may have any configuration.

  As shown in FIG. 5, the front surface (upper surface) of the suction grill 20 is provided with suction holes 25 having substantially the same dimensions at positions corresponding to the air suction ports 15, and positions corresponding to the air outlets 11 to 14, respectively. Are provided with blowout holes 21, 22, 23, 24 having substantially the same dimensions.

  As shown in FIG. 6, the main body base 30 includes ion generating elements 31 and 32 as ion generating units, a fan 33 having blades, a control unit 35 that controls the ion generating device 100, and a plurality of LEDs. A display unit 36, a voice detection device 50, and the like are attached.

  As shown in FIG. 6, the main body base 30 is configured so that a fan 33 is attached to the central portion. A portion of the bottom surface of the main body base 30 to which the fan 33 is attached forms a bowl-shaped throttle portion 37 that is narrowed in a circular shape from the outside to the inside. When the fan 33 operates, when the air flow sucked from the air suction port 15 hits the bottom surface of the main body base 30, the throttle portion 37 is formed, so that the sucked air flows into the bottom surface of the main body base 30. It can be made to flow smoothly along the air outlets 11 and can be guided to the air outlets 11 to 14 without causing air flow disturbance.

  A pair of opposing side walls of the main body base 30 are inclined so as to expand toward the front surface (upper surface), and the ion generating elements 31 and 32 are attached to the respective side walls. The ion generating elements 31 and 32 are attached to the side wall by being pressed by a fixing plate 34 having a locking portion formed at the tip. The ion generating elements 31 and 32 are detachably attached by a fixing plate 34.

  The ion generating element 31 is a rectangular plate-like body, and electrode needles 31a and 31b as electrode portions for generating negative ions are provided in the vicinity of one end portion at an appropriate distance, and in the vicinity of the other end portion.

Further, an ion generating electrode portion that generates negative ions is disposed in the vicinity of the blowout hole 23 and the air blowout port 13, and air containing negative ions is blown out from the blowout hole 23 and the air blowout port 13.

The ion generating elements 31 and 32 ionize water vapor in the air by plasma discharge, so that H ⁺ (H ₂ O) m (m is an arbitrary natural number) as positive ions and O ₂ ⁻ ( H ₂ O) n (n is 0 or any natural number). These chemically react to generate hydrogen peroxide (H ₂ O ₂ ) and / or hydroxyl radicals (OH), which are active species, and remove airborne bacteria and airborne viruses.

  Accordingly, each air outlet 11 to 14 can independently blow out air containing positive ions or air containing negative ions, and positive ions and negative ions in the air blown out from the ion generator 100 are generated. Immediate neutralization can be prevented. And ion diffusibility can be improved by preventing neutralization of ions.

  The display unit 36 includes a plurality of LEDs for displaying the operation state of the ion generator 100. For example, the display unit 36 indicates the operating conditions of the blue LED indicating that the ion generating elements 31 and 32 are operating, the red LED for notifying the replacement time of the filter attached to the air suction port 15, and the fan 33. Blue, green and red three-color LEDs shown are provided. In this case, corresponding to the rotation speed of the fan 33, the blue of the three-color LED is lit at a high speed (the air volume and the wind speed are large). Further, when the rotational speed is medium speed (air volume, wind speed is equivalent to medium), the green of the three-color LED is lit. When the number of revolutions is low (air volume, wind speed is small), the three-color LED does not light up. Moreover, when notifying the exchange time of the ion generating elements 31 and 32, blue and green of three-color LED blink. Further, when the front panel 10 is detached or not completely attached, all the LEDs of the display unit 36 are turned off.

As shown in FIG. 7, when the protruding bar 16 erected on the back side of the front panel 10 pushes the microswitch 351, the microswitch 351 is turned on, and it is detected that the front panel 10 is mounted. On the other hand, when the front panel 10 is detached, it is detected that the protruding bar 16 is separated from the micro switch 351 and the micro switch 351 is turned off and the front panel 10 is detached. When the front panel 10 is detached, the micro switch 351 is turned off, and the operation of the ion generator 100 is stopped or cannot be operated.

  As shown in FIG. 7, on the back side (rear side) of the suction grill 20, as a blow direction setting member having a depth (height) shorter than the depth of the main body base 30 with the suction hole 25 interposed therebetween. Ventilation walls 201, 201 are arranged as blowing direction setting members. That is, with the suction grill 20 attached to the main body base 30, a sufficient gap is provided between the inside of the bottom surface of the main body base 30 and the ventilation wall 201 so that the air sucked by the fan 33 flows. .

  The side wall of the ventilation wall 201 on the side of the outlet holes 21 to 24 has an inclined surface (inner wall) 201a as an outlet direction setting member that is tapered along the depth (height) direction. In addition, a ventilation plate 202 as a blowing direction setting member is provided at the center of the ventilation wall 201 and has a depth (height) of substantially the same size as the ventilation wall 201 and is sandwiched between the blowing holes 22 and 23. ing.

The vent plate 202 on the outlet holes 21 and 24 side has the same configuration.

  With the suction grill 20 attached to the main body base 30, the ventilation wall 201 and the ventilation plate 202 are connected to the air inlet 15 and the air outlets 11 to 14 together with the inner wall (the inner side of the bottom surface, the inner side surface, etc.) of the main body base 30. A communicating air passage R is formed. And the fan 33 is attached to the ventilation path R so that the rotating shaft of the blade | wing of the fan 33 may be orthogonal to the surface of the air suction inlet 15 and the air blower outlets 11-14.

  Further, as shown in FIGS. 7 and 10, on the back side of the blowout hole 22, rectifying plates 204, 204 as blowout direction setting members for setting the blowout direction of air are appropriately lengthened substantially parallel to the inclined surface 202 a. They are separated. Similarly, on the back side of the blowout hole 24, rectifying plates 204, 204 for setting the air blowing direction are provided at an appropriate distance from the inclined surface 202a.

  11 and 12 are schematic views showing an outline of the air ventilation path R. FIG. FIG. 11 shows the state of the ion generator 100 as viewed from the longitudinal direction, and FIG. 12 shows the state of the ion generator 100 as viewed from the short side. As shown in FIG. 11, the air is sucked from the air suction port 15 by operating the fan 33. The sucked air passes through the ventilation path R via the fan 33 and is blown out from the air outlets 11 to 14 (the air outlets 11 and 12 are not shown in FIG. 11). In FIG. 11, arrows indicate the air flow. When the air is blown out from the air outlet 13, negative ions generated at the negative ion generating electrode portion of the ion generating element 32 are contained in the air, and air containing the negative ions is blown out. Moreover, when it blows off from the air blower outlet 14, the positive ion which generate | occur | produced in the positive ion generation electrode part of the ion generating element 31 is contained in air, and the air containing a positive ion is blown out.

  In addition, the air blown from the air outlets 13 and 14 is diffused in a direction along the inclined surface 201a (a direction parallel to the inclined surface 201a) by the inclined surface 201a that is the inner wall of the ventilation path R. In addition, although the angle which the inclined surface 201a and the surface of the air blower outlets 13 and 14 make is preferable, for example, about 45 degree | times is not limited to this, About 30 degree-60 degree | times may be sufficient.

  Also, as shown in FIG. 12, air is sucked from the air suction port 15 by operating the fan 33. The sucked air passes through the ventilation path R via the fan 33 and is blown out from the air outlets 12 and 13 (the air outlets 11 and 14 are not shown in FIG. 12). In FIG. 12, arrows indicate the air flow. When the air is blown out from the air outlet 12, positive ions generated at the positive ion generating electrode portion of the ion generating element 32 are contained in the air, and air containing the positive ions is blown out.

  In addition, the air blown from the air outlets 12 and 13 by the inclined surfaces 202a and 202b which are the inner walls of the air passage R are directions along the inclined surfaces 202a and 202b (directions parallel to the inclined surfaces 202a and 202b), respectively. To spread. In addition, although the angle which the inclined surfaces 202a and 202b and the surface of the air blower outlets 12 and 13 make is preferably about 45 degrees, for example, it is not limited to this and may be about 30 to 60 degrees.

  FIG. 13 is a front view of the front panel 10, and FIG. 14 is a cross-sectional view of the main part of the air outlet 11. As shown in FIG. 13, the air outlet 11 of the front panel 10 has a slit shape in which a partition plate 111 as a plurality of blowing direction setting members is juxtaposed in the opening 112. Thereby, the air blower outlet 11 has a function as an air guide plate. Moreover, as shown in FIG. 14, the partition plate 111 is inclined along the blowing direction of the air outlet 11, and the inclined blowing plate 111 changes the air blowing direction as shown by the arrow in FIG. Can be set. For example, instead of providing the partition plate 111 at a right angle to the surface on which the air outlets 11 are provided, air containing ions is formed by inclining the surface with a required inclination angle (for example, 45 degrees). Can be inclined from the air outlet 11 in accordance with the inclination of the partition plate 111. Thereby, the diffusibility of ions can be further enhanced. The other air outlets 12 to 14 have the same configuration.

  FIG. 15 is an explanatory view showing an example of the air blowing direction of the ion generator 100 according to the present invention. In FIG. 15, arrows indicate the blowing direction of air from the air outlets 11 to 14. About the air blower outlet 11, the longitudinal direction outer side of the ion generator 100 by the inclination of the inclined surface 201a as an inner wall of the ventilation wall 201, the inclined surface 202b of the ventilation board 202, and the partition plate provided in the air blower outlet 11 ( Air containing negative ions is diffused toward the left in FIG.

  Further, with respect to the air outlet 12, ions are generated by the inclined surface 201 a as the inner wall of the ventilation wall 201, the inclined surface 202 a of the ventilation plate 202, the rectifying plates 204 and 204, and the inclination of the partition plate provided at the air outlet 12. Air containing positive ions is diffused toward the outside in the short direction of the apparatus 100 (upward in FIG. 15).

  Further, with respect to the air outlet 13, the longitudinal direction of the ion generator 100 is determined by the inclined surface 201 a as the inner wall of the ventilation wall 201, the inclined surface 202 b of the ventilation plate 202, and the inclination of the partition plate provided at the air outlet 13. Air containing negative ions is diffused outward (to the right in FIG. 15).

  Further, with respect to the air outlet 14, ions are generated due to the inclined surface 201 a as the inner wall of the ventilation wall 201, the inclined surface 202 a of the ventilation plate 202, the rectifying plates 204 and 204, and the inclination of the partition plate provided at the air outlet 14. Air containing positive ions is diffused toward the outside in the short direction of the device 100 (downward in FIG. 15).

  Thus, the ion generator 100 is provided with a plurality of air outlets 11 to 14 on the same plane as the air inlet 15 and around the air inlet 15. Thereby, the air sucked from the air suction port 15 disposed in the central portion becomes air containing ions inside the ion generator 100, and a plurality of air outlets provided around the air suction port 15. Since it blows out from 11-14, the diffusibility of ion can be improved. In particular, even when the ion generator 100 is attached to the ceiling or wall of the room, the plurality of air outlets 11 to 14 are provided, so that ions can be efficiently diffused into the room.

  Further, by making the air outlet 11 (or 13) containing negative ions and the air outlet 14 (or 12) containing positive ions independent (separately separated), the positive ions and the negative ions are kept in the middle. It is possible to increase the ion diffusibility by avoiding the sum.

  Moreover, the ion generating electrode part is provided in the vicinity of each air outlet 11-14. For example, in the vicinity of the air outlets 11 and 13 for blowing out air containing negative ions, an electrode part (for example, an electrode needle) for generating negative ions is provided, and the air outlet 12 for blowing out air containing positive ions. , 14 is provided with an electrode portion (for example, an electrode needle) for generating positive ions. Thereby, for example, it is possible to prevent the ions from disappearing in the air passage R leading to the air outlets 11 to 14, and to blow out the generated positive ions and negative ions from the air outlets 11 to 14, Ions can be diffused more efficiently.

  Further, as shown in FIG. 15, air outlets for blowing out air containing positive ions and air outlets for blowing out air containing negative ions are alternately arranged in a circumferential shape. For example, when the air outlets are arranged at the positions of the four corners of the rectangle, the air outlets for positive ions and the air outlets for negative ions are arranged in order. In this case, the polarities of the ions at the air outlet on the diagonal line are the same. Thereby, the positive ions and the negative ions can be diffused uniformly, the ion distribution in the space is improved, and neutralization of the ions can be avoided.

  Moreover, since the air blower outlets 11-14 are provided in the same plane as the air suction inlet 15, for example, when installing the ion generator 100 in a ceiling or a wall, the air blower outlets 11-14 and the air suction inlet 15 are provided. It can be made the same surface as the ceiling surface or wall surface, and the restriction that the ion generator must be installed in a state of protruding from the ceiling surface or wall surface can be eliminated, and the appearance is also improved.

  Moreover, as shown in FIG. 15, the blowing direction along the said same plane of the air which blown off from each air blower outlet 11-14 can be set to a different direction equally, respectively. In the example of FIG. 15, as an example, the air outlets 11 to 14 are arranged at the positions of the four corners of the rectangle, and the direction of the air blown out from each air outlet 11 to 14 is substantially the same as the direction from the adjacent air outlet. Make a right angle. Thereby, ion can be spread | diffused equally to four directions from the attachment surface of the air blower outlets 11-14 of the ion generator 100. FIG.

  Moreover, the ion generator 100 has the fan 33 which has the blade | wing rotating around the axis | shaft orthogonal to the surface of the air blower outlets 11-14 and the air suction inlet 15 in the ventilation path. By operating the fan 33, the air sucked from the air suction port 15 is blown out from the air outlets 11 to 14 through the ventilation path R. And the blowing direction from each air blower outlet 11-14 is set to the direction which corresponds with the rotation direction (arrow direction of FIG. 15) of a blade | wing. For example, as shown in FIG. 15, when the rotation direction of the fan 33 is counterclockwise, the blow direction is set so that the blow direction from each of the air outlets 11 to 14 is counterclockwise. Thereby, air containing ions can be blown out against the flow of spiral air generated by the rotation of the fan 33, and ion diffusibility can be improved.

  In addition, the blowing direction of the air from the air blower outlets 11-14 is not limited to the example of FIG. 15, The other direction may be sufficient. FIG. 16 is an explanatory view showing another example of the air blowing direction of the ion generator 100 according to the present invention. In FIG. 16, the arrow shows the blowing direction of the air from the air blower outlets 11-14. As shown in FIG. 16, the air blowing directions from the air outlets 11 to 14 are four directions from the center of the fan 33 along the radial direction. In this case, for example, the air blowing direction can be set as in the example of FIG. 16 by changing the direction of the partition plates of the air outlets 11 to 14 in plan view.

In this embodiment, H ⁺ (H ₂ O) m (m is an arbitrary natural number) as a positive ion and O ₂ ⁻ (H ₂ O) n (n is 0 or an arbitrary natural number) as a negative ion. ) To remove airborne bacteria, airborne viruses, etc., but only O ₂ ⁻ (H ₂ O) n (n is 0 or any natural number) as negative ions is generated. In particular, airborne bacteria and the like in the air can be removed. In this case, the negative ions generated by the ion generating element chemically react with H ⁺ (H ₂ O) m (m is an arbitrary natural number) as positive ions originally present in the air, and are active species. Hydrogen oxide (H ₂ O ₂ ) and / or hydroxyl radicals (OH) are generated, and airborne bacteria and airborne viruses are removed. However, since the positive ions originally present in the air are less than the positive ions generated by the plasma discharge of the ion generating element, the sterilization efficiency of airborne bacteria etc. generates both positive ions and negative ions. It is inferior to the case where it was made to.

<Control configuration>
The control supply circuit (5V) 352 generates DC 5V and supplies the DC 5V to the microcomputer 350, the memory 354, and the like. The control supply circuit (12V) 353 generates DC 12V, and supplies DC 12V to the PCI control circuits 356 and 357, the fan control circuit 358, and the like.

  Each of the PCI control circuits 356 and 357 receives a command from the microcomputer 350 and controls driving conditions such as driving and stopping of the ion generating elements 31 and 32. For example, the ion generating elements 31 and 32 are continuously driven (ion is continuously generated), or the ion generating elements 31 and 32 are intermittently driven (on / off is repeated at predetermined intervals to intermittently generate ions. To generate). In the intermittent drive, for example, the ion generating elements 31 and 32 are turned on with a required variable duty ratio (for example, a ratio of the on time to the total time of the on time and the off time) or a variable period (for example, while maintaining the duty ratio). Driving conditions for turning on / off at each of time and off time, and the total time of on time and off time). When the ion generating elements 31 and 32 are intermittently driven, one ion generating element is driven and the other ion generating element is alternately driven (alternating) so as to stop.

  The fan control circuit 358 includes a PWM (pulse width modulation) circuit, receives a command from the microcomputer 350, adjusts the rotation speed of the fan 33, detects the rotation speed of the fan 33, and outputs it to the microcomputer 350. To do. The fan control circuit 358 has a high rotational speed of the fan 33 (for example, a state where the air volume or wind speed is large at 3000 times / minute), a medium speed (for example, a state where the air volume or wind speed is medium at 2700 times / minute), and a low speed. The fan 33 is operated under three operating conditions (for example, a state where the air volume or the wind speed is small at 2400 times / minute). The operating condition is merely an example, and is not limited to the configuration in which the rotation speed is divided into three stages, and may be divided into many other stages, or the rotation speed of the fan 33 is continuously variable. You can also The fan 33 can also be rotated in the reverse direction.

  There is a correlation between the amount of ions generated and the number of rotations of the fan 33. The larger the amount of air generated by the rotation of the fan 33, the larger the amount of ions generated and the higher the ion concentration in the space where the ions are blown out. Therefore, by operating the fan 33 at a high speed, the concentration of ions contained in the air blown out from the air outlets 11 to 14 increases.

  The remote control light receiving unit 355 receives infrared light from a remote control (not shown) and extracts a signal from the received light. For example, the remote control light receiving unit 355 receives signals such as operation start, operation stop, and operation condition setting of the ion generator 100.

  In addition, although the ion generator 100 of this Embodiment shows the structure provided with the two ion generating elements 31 and 32, the number of ion generating elements is not limited to two pieces.

  Next, the operation of the ion generator in this embodiment will be described. FIG. 18 is a flowchart showing a processing procedure of the control unit 35. The control unit 35 determines whether or not the power is turned on (S11). If the power is not turned on (NO in S11), the process of step S11 is continued. When the power is turned on (YES in S11), the control unit 35 determines whether or not the entire panel 10 is closed (S12). If not (No in S12), that is, the entire panel 10 is detached. If it is present, or if it is not completely attached, the full-panel 10 outputs “open” information (for example, LED is turned off) (S13), and the processing after step S12 is continued.

  When the entire panel 10 is closed (YES in S12), the control unit 35 continuously drives the ion generating elements 31 and 32, and the fan 33 is in a medium speed (for example, 2700 times / min. ) (S14).

  Next, the control unit 35 determines the volume of the sound detected by the sound detection device 50 (S15). If it is determined that the detected volume is less than the predetermined value (NO in S15), the fan 33 continues to operate at a medium speed and continues the process of step S15.

  When it is determined that the detected sound volume is equal to or higher than the predetermined value (YES in S15), the fan 33 is changed from the operation at the medium speed to the operation at a high speed (for example, the air volume or the wind speed is large at 3000 times / minute). Switching (S16). Further, the timer is turned on (S17), and it is determined whether or not a predetermined time has elapsed (S18). If the predetermined time has not elapsed (NO in S18), the control unit 35 continues the process in step S18. If the predetermined time has elapsed (YES in S18), the control unit 35 switches the fan to the medium speed operation (S19). The control unit 35 again determines the volume of the sound detected by the sound detection device 50 (S15).

  If the operation sound is anxious even if the fan 33 is operated at medium speed, such as in a very quiet vehicle, the fan operation in steps S14 and S19 is performed at low speed instead of medium speed. (For example, the air volume or the wind speed is small at 2400 times / minute).

<Modification 1 of Control Configuration>
The operation of the ion generator can be performed by a processing procedure as shown in the flowchart of FIG.

  In the flowchart of FIG. 19, the process up to step S16 is the same as that of FIG. Hereinafter, only step S16 and subsequent steps will be described. The fan 33 is switched to high speed operation (S16), and the timer is turned on (S21). Next, the volume of the sound detected by the sound detection device 50 is determined (S22). If it is determined that the detected volume is equal to or higher than the predetermined value (YES in S22), the timer is reset (S23), the timer is turned on again (S21), and the process of step S22 is performed.

  If it is determined that the detected volume is less than the predetermined value (NO in S22), it is determined whether or not a predetermined time has elapsed in step S24. If the predetermined time has not elapsed (NO in S24), the control unit 35 continues the processing from step S22. If the predetermined time has elapsed (YES in S24), the control unit 35 switches the fan to medium speed operation (S25). The control unit 35 again determines the volume of the sound detected by the sound detection device 50 (S15).

  In this modified example, when another first in-vehicle announcement is detected while the first in-vehicle announcement is detected and the fan 33 is operating at high speed, the timer is reset, and the second in-vehicle announcement is displayed. The fan 33 is operated at a high speed until a predetermined time elapses after the detection.

  In general, on the Shinkansen and limited express trains, in-car announcements are mainly intermittent from a few minutes before the vehicle stops at the station until it leaves the station. According to the processing procedure of the first modification, by setting the predetermined time in step S24 to be longer than the interval between the announcements in the vehicle, the predetermined time has elapsed since the departure from the announcement in the vehicle before the vehicle stopped at the station. The fan 33 can be continuously operated at a high speed until later.

<Modification Example 2 of Control Configuration>
In the second modification, the in-vehicle announcement detected by the voice detection device 50 is voice-recognized by the microcomputer 350, and only a specific voice is detected to control the operation of the ion generator 100. Specifically, the processing procedure as shown in the flowchart of FIG. 20 is performed.

  In the flowchart of FIG. 20, the process up to step S14 is the same as that of FIG. Hereinafter, only step S14 and after will be described. The fan 33 is operating at medium speed (S14). Next, the control unit 35 recognizes the voice detected by the voice detection device 50 and determines whether or not the voice means “arrival at the station” stored in advance in the memory 354 (S31). When it is determined that the detected voice is not a voice meaning “arrival at the station” (NO in S31), the fan 33 continues to operate at a medium speed, and the process of step S31 is continued. When it is determined that the detected sound is a sound meaning “arrival at the station” (YES in S31), the fan 33 is switched from the medium speed operation to the high speed operation (S32). Here, it is assumed that the voice meaning “arrival at the station” is a voice detected when two words “soon” and “arrival” are detected within a predetermined time.

  Next, the control unit 35 recognizes the voice detected by the voice detection device 50 and determines whether the voice means “departure from the station” stored in the memory 354 in advance (S33). If it is determined that the detected voice is not a voice meaning “departing from the station” (NO in S33), the fan 33 continues to operate at a high speed and the processing in step S33 is continued. If it is determined that the detected sound is a sound meaning “departing from the station” (YES in S33), the timer is further turned on (S34), and it is determined whether or not a predetermined time has passed (S35). If the predetermined time has not elapsed (NO in S35), the control unit 35 continues the process of step S35. If the predetermined time has elapsed (YES in S35), the fan is switched to the medium speed operation (S36). The control unit 35 again determines the sound detected by the sound detection device 50 (S31). Here, it is assumed that the voice meaning “departing from a station” is a voice detected when two words “soon” and “departure” are detected within a predetermined time.

  Note that the voice meaning “arrival at the station” and the voice meaning “departing from the station” are stored in the memory 354, so that an arbitrary announcement can be made according to the announcement in the vehicle where the ion generator is installed. It can be voice.

  According to the processing procedure of the second modification, without detecting an in-vehicle announcement other than when the vehicle stops at the station, the in-vehicle announcement is detected only when the vehicle stops at the station, and the fan 33 is operated at high speed. Can do.

[Second Embodiment]
<Overall configuration>
FIG. 21 shows a schematic view of a cross section of a vehicle. This is a schematic view of a vehicle in which seats are lined up in the traveling direction of the vehicle, such as the Shinkansen and limited express trains.

  In the vehicle in the present embodiment, as shown in FIG. 21, a plurality of seats 2 are provided facing the traveling direction of the vehicle, and two seats 2 for two persons are arranged in the left-right direction, and are arranged in a plurality of rows. ing. A passage 3 is provided between the seats 2. An ion generator 100 is recessed in the ceiling of the vehicle. In this embodiment, the ion generators 100 are installed in multiple rows, one on each side of the vehicle ceiling. Each ion generator 100 is installed such that the air inlet 15 faces the vicinity of the passage 3 of the vehicle.

  The arrows in FIG. 21 indicate the flow of ions and air blown from the air outlets 11 to 14 during normal operation (the fan rotates in the forward direction). The white arrow indicates the flow of ions and air blown out from the air suction port 15 when the fan rotates in the reverse direction.

  By installing in this way, as will be described later, by rotating the fan 33 of the ion generating device 100 in the reverse direction, air including both positive ions and negative ions is passed from the air inlet 15 to the periphery of the passage 3. Therefore, the ion concentration around the passage 3 can be increased. Further, ions can be directly blown out toward the passenger passing through the passage 3. Thereby, it is possible to efficiently sterilize or inactivate airborne bacteria, airborne viruses, and the like that are brought into the vehicle by passengers getting on and off, or that have risen as passengers move.

<Modification of overall configuration>
Here, a modified example of the overall configuration will be described. FIG. 22 shows a schematic view of a cross section of the vehicle. As shown in FIG. 22, unlike the embodiment of FIG. 21, ions blown out from the air outlets 11 to 14 indicated by arrows in FIG. . As a result, when the passenger does not move for getting on and off, not only the ions are diffused in the vicinity of the passenger in the vehicle, but also bacteria and the like attached to the passenger's luggage placed on the luggage rack 4 are sterilized at the same time. Can do.

<Ion generator>
The ion generator 100 is the same unit as in the first embodiment. The fan 33 can be rotated in the reverse direction. FIG. 23 shows the ion generator 100 as viewed from the longitudinal direction. When rotating in the reverse direction, the relationship between the air outlets 11 to 14 and the air inlet 15 is reversed. That is, as shown in FIG. 23, by operating the fan 33, air is sucked from the air outlets 11 to 14 (the air outlets 11 and 12 are not shown in FIG. 23). The sucked air passes through the ventilation path R via the fan 33 and is blown out from the air suction port 15. In FIG. 23, the arrows indicate the air flow. When air is sucked from the air outlet 13, negative ions generated at the negative ion generating electrode portion of the ion generating element 32 are included in the air, and air including negative ions is sucked. Further, when sucked from the air outlet 14, positive ions generated at the positive ion generating electrode portion of the ion generating element 31 were included in the air, air containing positive ions was sucked, and sucked from the air outlet 13. The air containing negative ions merges, and air containing both positive ions and negative ions is blown out from the air inlet 15.

<Control configuration>
Only the operation of the ion generator, which is the difference from the first embodiment, will be described.

  FIG. 24 is a flowchart showing a processing procedure of the control unit 35. The control unit 35 determines whether or not the power is turned on (S11). If the power is not turned on (NO in S11), the process of step S11 is continued. When the power is turned on (YES in S11), the control unit 35 determines whether or not the entire panel 10 is closed (S12). If not (No in S12), that is, the entire panel 10 is detached. If it is present, or if it is not completely attached, the full panel outputs “open” information (for example, the LED is turned off) (S13), and the processing after step S12 is continued.

  When the entire panel 10 is closed (YES in S12), the control unit 35 continuously drives the ion generating elements 31 and 32 (S13), and the fan 33 is driven at a medium speed (for example, 2700 times / minute). In the middle state) (S141). The rotation direction of the fan is the same as that in the first embodiment (hereinafter referred to as the forward direction).

  Next, the control unit 35 determines the volume of the sound detected by the sound detection device 50 (S15). If it is determined that the detected volume is less than the predetermined value (NO in S15), the fan 33 continues to operate at a medium speed and continues the process of step S15.

  When it is determined that the detected sound volume is equal to or higher than the predetermined value (YES in S15), the fan 33 is changed from the operation at the medium speed to the operation at a high speed (for example, the air volume or the wind speed is large at 3000 times / minute). At the same time, the rotation direction of the fan 33 is reversed (S161). Further, the timer is turned on (S17), and it is determined whether or not a predetermined time has elapsed (S18). If the predetermined time has not elapsed (NO in S18), the control unit 35 continues the process of step S18. If the predetermined time has elapsed (YES in S18), the control unit 35 switches the fan to the medium speed operation, and at the same time the fan 33 The rotation direction is returned to the forward direction (S191). The control unit 35 again determines the volume of the sound detected by the sound detection device 50 (S15).

  If the operation sound is anxious even if the fan 33 is operated at a medium speed, such as in a very quiet vehicle, the fan operation in steps S141 and S191 is not a medium speed but a low speed. (For example, the air volume or the wind speed is small at 2400 times / minute).

  In step S161, it is possible to reverse only the rotation direction of the fan 33 while the fan 33 is operated at a medium speed. Since air containing ions is blown out from one air suction port 15, even if the fan 33 remains at a medium speed, it is blown out intensively from the ion generator toward the periphery of the passage 3. Sufficient ion concentration can be obtained at the periphery.
