Description

  The present invention relates to a vehicle ion generator.

  Traditionally, negative ions have been known to have a relaxing effect, moisturize and smooth hair, and moisturize by direct contact with the skin. It is known to have a fungal effect.

  Patent Document 1 discloses that a negative ion generator is provided in a ceiling portion of a vehicle such as a passenger car so that negative ions are blown out into the passenger compartment.

  However, even if ions are released into the passenger compartment, the passenger in the vehicle is electrically insulated from the outside and the potential is not determined. Therefore, in the conventional example, when negative ions are released from the ion generator into the passenger compartment, if the passenger is positively charged and the negative ions hit the passenger's body or clothes, The charged electric charge is neutralized and further negatively charged. In this state, the passenger side has the same polarity as the negative ions generated from the ion generator, so the negative ions generated by repulsion are not attracted and adsorbed to the passenger side, and the negative ions relax the passenger Or, the effect of moisturizing the hair and the effect of moisturizing the skin cannot be continuously exhibited.

Similarly, when positive ions are released from the ion generator into the passenger compartment, if the occupant is negatively charged and the positive ions hit the occupant's body or clothes, the charged body or clothes will be charged. Neutralized and further positively charged. In this state, the passenger side has the same polarity as the negative ions generated from the ion generator, so it will repel and the charged particulate water will not be attracted and adsorbed to the passenger side, and the passenger's body and clothes due to positive ions The sterilization effect of the virus and bacteria attached to the can not be exhibited continuously.

  FIG. 1 shows a schematic view of a vehicle 1 such as an automobile, and the vehicle 1 is provided with a vehicle ion generator 2.

  The vehicle ion generator 2 includes an ion generator 3 and a potential holding unit 4.

  The ion generator 3 generates air ions (minus air ions or plus air ions) by corona discharge, and includes a needle electrode 5 and high voltage applying means 6 for applying a high voltage to the needle electrode 5; It has an outlet 19 for releasing ions generated by applying a high voltage to the needle electrode 5 into the passenger compartment 1a.

  Here, for example, when generating negative air ions (hereinafter referred to as negative ions), DC-5 kV is applied to the needle electrode 5, and when generating positive air ions (hereinafter referred to as positive ions), the needle electrode 5 is applied. DC + 5 kV is applied.

  The ion generator 3 having the above-described configuration is provided in the vehicle 1 and discharges ions into the passenger compartment 1a. The ion generator 3 is operated by turning on the switch.
