In such a configuration, the ion generator 10 is moved to the lower side (in FIG. 3) by the moment due to the weight of the ion generator 10 with the fastening portion 46 provided on the one end 23m side of the back surface portion 23 as a fulcrum. There is a risk of tilting in the direction indicated by the arrow 103. In particular, when an adapter is connected to the power input unit 36, the pulling force acts on the ion generator 10 depending on the weight and state of the adapter, and the above-described concerns increase.

  On the other hand, in the ion generator 10 according to the present embodiment, the air sucked through the suction port 31 provided on the other end 23n side of the back surface portion 23 changes its direction in the casing 21, and the suction port 31.

The ion generator 80 includes a casing 84, an ion generation part 81 having a discharge electrode 82, and a fastening part 83. Ion generator 80 has basically the same configuration as ion generator 10 in the first embodiment, but differs in that it does not have a fan in casing 84.

  In the present embodiment, the air blown from the air blowing port 120 flows into the casing 84 along the direction indicated by the arrow 131 through a suction port (not shown). The air is discharged into the vehicle compartment along the direction indicated by the arrow 132 through a blowout port (not shown) together with ions generated at the discharge electrode 82 in the casing 84.

  An adapter 71 electrically connects a power input unit 87 provided in the ion generator 80 and a power output unit 56 provided in the vehicle. Through the adapter 71, electric power is provided on the vehicle and used to drive the ion generator 81 from the power source to the ion generator 80.

  According to the ion generator comprised in this way, an ion generating part can be driven using the electric power generated with rotation of a fan.

  Preferably, the fastening part (46) has a movable part (48) movable so that the posture of the casing (21) changes.

  According to the ion generator configured in this way, the air flow in the casing cancels out the moment due to the weight of the ion generator with the movable part as a fulcrum, so the attitude of the ion generator changes unintentionally. Can be prevented.

  The vehicle-mounted unit of the ion generator according to the present invention has an ion generator (81) that generates ions when a voltage is applied, and a louver (121) of an air outlet (120) provided on the vehicle. ) And an adapter (71) connected to a power source provided on the vehicle and supplying power from the power source to the ion generator (80). The ion generator (80) includes a high voltage generation circuit unit (86) for boosting a voltage input from a power source and applying a high voltage to the ion generation unit (81). The adapter (71) has a drive circuit unit (72) for receiving the voltage input from the power source and driving the high voltage generation circuit unit (86).

  According to the vehicle-mounted unit of the ion generator configured as described above, the ion generator can be reduced in size by providing the adapter with the drive circuit unit for driving the high voltage generation circuit unit. Thereby, since it is suppressed that the air-conditioning wind from a ventilation opening is interrupted by the ion generator, ion can be discharge | released in a vehicle interior, without impairing the original air-conditioning performance of a vehicle.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention is mainly applied to an in-vehicle type ion generator.
