It is mounted on the substrate support 15.
- the support plate 8 on which the blowing means 9 is mounted is mounted on the front housing 2a such that the discharge surface of the ion generator 4 is exposed from the opening 8a.
- the rear housing 2b is attached to the front housing 2a.
- the operation button 11 is inserted into a predetermined hole of the front housing 2a of the main body 2, and a display sheet is attached to the upper surface of the front housing 2a.
- one end of the connection cord 92 is inserted into the plug insertion port 25 of the rear housing 2b, and the lid 2c is put on the rear housing 2b.
- the outlet 27 corresponding to the storage depth of the beverage container holder 90 in which the in-vehicle air purification device 1 is to be stored is selected, and the connection cord 92 is pulled out from the selected outlet 27. Then, the lid 2c is put on the rear housing 2b.
- the in-vehicle air purification device 1 is housed in a beverage container holder 90 in the vehicle, and the other end of the connection cord 92 is inserted into a power supply 91 for a cigarette lighter in the vehicle. Is mounted inside the car.
- the operation button 11 is pressed to select a desired mode as the operation mode of the device. Then, electricity is supplied to the ion generator 4 and the blowing means 9 via the power supply board 6, and each is driven. To start.
- the air force outside the main body 2 is taken into the main body 2 via the suction port 26 of the main body 2, the filter and the air inlet 22, and is discharged to the discharge surface of the ion generator 4. Supplied to At this time, the air sent from the blowing means 9 hits the guide plate 23 and enters the discharge surface of the ion generator 4 at an acute angle.
- the ion generator 4 performs an operation according to the operation mode of the device, and generates, for example, both positive and negative ions and negative rich ions by discharging on the discharge surface. At this time, the LEDs 52 and 53 emit a color according to the operation mode of the device.
- the ions generated by the ion generator 4 are mixed with the remaining air supplied from the blowing means 9, but the air supplied from the blowing means 9 is obliquely incident on the discharge surface from below. Therefore, the air after mixing is directed upward along the discharge surface, is compressed by the compression member 24 (after its flow rate is reduced), and then increases in flow velocity to form a main body through the outlet 21. 2 It is blown out.
- the air containing ions discharged from the outlet 21 is radiated into the vehicle along with the flow of air for cooling / heating blown out from the outlet 93 in the vehicle if the air conditioner in the vehicle is driven.
- the action destroys airborne bacteria and purifies the air in the car, that is, the air in the car Suspended bacteria are inactivated and removed.
- Inactivation refers to the action of disinfecting, removing, and sterilizing airborne bacteria, and the action of decomposing and removing viruses.
- the on-vehicle air purification device 1 of the present embodiment is mounted on a vehicle and includes the main body 2 having the ion generator 4 for generating one or both of positive ions and negative ions.
- the main body 2 is configured to be detachably installed in a seat space in a vehicle (for example, a beverage container holder 90).
- the ions generated by the ion generator 4 are discharged directly into the seat space in the vehicle after being discharged from the main body 2, so that the number of collisions between the released ions and the outside is, for example, the ion generator.
- Is installed in the passage inside the air outlet for cooling and heating, and the number of ions is much smaller than in the past where ions collided with the passage and the outlet. Therefore, if the ion generation capacity (ion generation amount per unit time) of the ion generator 4 is fixed, the supply efficiency of ions supplied into the seat space can be improved as compared with the conventional case.
- the main body 2 is detachably installed in the seat space by itself, even if the ion generator 4 needs to be replaced due to a failure or the like, the installed ion generator 4 is immediately removed. It can be easily removed and replaced.
- the ion generator 4 can be retrofitted to a vehicle that is not equipped with the ion generator 4, and the convenience can be improved.
- a vibration sensor for detecting vibration according to the traveling speed of the vehicle
- the control board 7 controls the operation mode of the device according to the amount of vibration detected by the vibration sensor.
- the mode may be automatically switched. For example, when the vibration sensor detects vibrations corresponding to high-speed or low-speed running of the vehicle, the operation mode of the device is set to “ion control mode”, which has a high relaxing effect by negative ions, to support medium-speed running of the vehicle.
- the vibrations detected by the vibration sensor are detected by the control board,
- the troublesome operation during driving such as switching by pressing the driver's operation button 11 can be eliminated, and the air in the vehicle can be automatically adjusted according to the mental state of the driver.
- the main body 2 is provided with a time-measuring means (timer) for measuring the low-speed running time, and the low-speed running is detected by the vibration sensor, and the low-speed running for a predetermined time or more is detected by the time-measuring means.
- timer time-measuring means
- the control board 7 may automatically switch the operation mode of the apparatus to the “ion control mode”. In this case, it is possible to determine that the vehicle is driving during traffic congestion, and the "ion control mode" releases relatively large amounts of negative ions into the interior of the vehicle to reduce driver irritation. Thus, safe driving can be encouraged.
- the vehicle-mounted air purification device 1 of the present invention may have the following configuration.
- the in-vehicle air purification device 1 discharges the air sucked from the air blowing means 9 to the discharge surface of the ion generation device 4 from an oblique direction and discharges the air from the air outlet 21 to remove bacteria floating in the air. It is a configuration to remove.
- the air outlet 21 of the on-vehicle air purification device 1 has an emission control that regulates the flow of air so that air containing ions generated by the ion generator 4 blows out forward of the main body 2. This is a configuration in which means are formed.
- the vehicle-mounted air purification device 1 is configured such that the ion generator 4 is arranged so that the discharge surface is located near the air outlet of the blowing means 9.
- the passage area of the air from the ion generator 4 toward the outlet 21 is smaller than the passage area of the air supplied from the blowing means 9 to the ion generator 4.
- a flow rate regulating means compression member 24 for regulating the flow rate of the air is formed from the ion generator 4 to the outlet 21.
- the main body 2 of the on-vehicle air purification device 1 is divided into front and rear parts, and a display unit (light guide 3) for performing a display according to the operation mode of the device is provided on a divided surface of the main body 2. It is a configuration that has been formed.
- the display section is formed so as to extend over the upper surface and the peripheral surface of the main body 2.
- the power supply (power supply board 6, plug insertion port 25) for driving the on-vehicle air purification device 1 is configured to be connectable to a power supply 91 for a cigarette lighter in the vehicle.
- a plurality of outlets 27 are provided in the height direction of the main body 2 so that a connection line for connecting the power supply for driving the on-vehicle air purification device 1 and the power supply 91 for the cigarette lighter in the vehicle is drawn out from the main body 2.
- the structure is formed as follows.
- the configuration is provided with a noise countermeasure (shield member 36) for suppressing radiation noise generated in the booster coil 35 of the circuit board 32 of the ion generator 4.
- a noise countermeasure shield member 36 for suppressing radiation noise generated in the booster coil 35 of the circuit board 32 of the ion generator 4.
