The purifying box 5 is provided, for example, on an instrument panel 14 called a so-called instrument panel provided in the front part of the passenger compartment 8 of the vehicle 7, or a small case provided between a driver seat and a passenger seat. The box 29 is used as the purification box 5 or provided in another part of the passenger compartment 8.

  When provided on the instrument panel 14, the dashboard provided in the instrument panel 14 may be used as the purification box 5, or the purification box 5 may be provided on the instrument panel 14 separately from the dashboard.

  FIG. 1 shows an example in which the purification box 5 is provided on the instrument panel 14 separately from the dashboard.

  The purification box 5 is provided with an openable / closable door or can be pulled out so that small items such as gloves, handkerchiefs, towels or hats brought into the vehicle 7 can be put inside. .

  The vehicle 7 is provided with an electrostatic atomizer 6. The electrostatic atomizer 6 includes a discharge electrode 1, a counter electrode 2 facing the discharge electrode 1, a high voltage applying means 15 for applying a high voltage between the discharge electrode 1 and the counter electrode 2, and the discharge electrode Charged fine particles generated by electrostatically atomizing water supplied to the discharge electrode 1 by applying a high voltage between the water supply means 3 for supplying water 1 and the discharge electrode 1 and the counter electrode 2 It has a discharge port 4 for discharging water into the purification box 5.

  FIG. 3 shows a schematic configuration diagram of an electrostatic atomizer main body 6a constituting the main body of the electrostatic atomizer 6 used in the present invention. In the embodiment shown in FIG. 3, water is supplied to the discharge electrode 1 by cooling the moisture in the air by the cooling means 17 such as the Peltier unit 16 to generate condensed water. Therefore, in this embodiment, the cooling means 17 constitutes the water supply means 3 that supplies water to the discharge electrode 1.

  The Peltier unit 16 has a pair of Peltier circuit boards 18 each having a circuit formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity, facing each other so that the circuits face each other, and arranged in multiple rows. The BiTe-based thermoelectric element 19 is sandwiched between the two Peltier circuit boards 18 and the adjacent thermoelectric elements 19 are electrically connected by the circuits on both sides, to the thermoelectric element 19 formed through the Peltier input lead wire 20. Is configured such that heat is transferred from one Peltier circuit board 18 side toward the other Peltier circuit board 18 side. In addition, a cooling unit 21 is connected to the outside of the Peltier circuit board 18 on one side, and a heat dissipation unit 22 is connected to the outside of the Peltier circuit board 18 on the other side. Then, an example of a heat radiating fin is shown as the heat radiating portion 22. The rear end of the discharge electrode 1 is connected to the cooling part 21 of the Peltier unit 16.

  The discharge electrode 1 is surrounded by a cylindrical body 23 made of an insulating material, and a counter electrode 2 having a ring shape is disposed at a tip opening of the cylindrical body 23, and a ring shape is formed on an extension line of the axial center of the discharge electrode 1. The discharge electrode 1 and the counter electrode 2 face each other so that the center of the ring of the counter electrode 2 is located.

  A battery mounted on the vehicle 7 is used as the high voltage application means 15 for applying a high voltage between the discharge electrode 1 and the counter electrode 2.

  In the electrostatic atomizer 6, the cooling unit 21 is cooled by energizing the Peltier unit 16 that is the cooling unit 17, and the discharge electrode 1 is cooled by cooling the cooling unit 21, and moisture in the air The water is condensed to supply water (condensed water) to the discharge electrode 1. When a high voltage is applied between the discharge electrode 1 and the counter electrode 2 in a state where water is supplied to the discharge electrode 1 in this manner, the discharge electrode is caused by the high voltage applied between the discharge electrode 1 and the counter electrode 2. The Coulomb force acts between the water supplied to the tip of 1 and the counter electrode 2, and the liquid level of water locally rises in a cone shape (tailor cone). When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). Receiving and generating a large amount of negatively charged nanometer-size charged fine particle water that repeatedly splits and scatters (Rayleigh split) beyond the surface tension, and the generated charged fine particle water is exposed to the outside from the opening at the tip of the cylinder 23 To be released.

However, the water is stored in the water reservoir, and the water in the water reservoir is collected using the capillary phenomenon or the like. You may make it comprise the water supply means 3 by supplying to a part.

  The electrostatic atomizer main body 6a constituting the main body of the electrostatic atomizer 6 having the above-described configuration is disposed, for example, in the instrument panel 14.

  The electrostatic atomizer main body 6a is disposed at one end of the carry-out path 10, and the other end of the carry-out path 10 opens to the lower surface of the instrument panel 14 to form the discharge port 4, The charged fine particle water released from the tip opening of the cylindrical body 23 generated by the atomizing device main body 6 a passes through the carry-out path 10 and is discharged from the discharge port 4 into the purification box 5 and put into the purification box 5. The nanometer-sized charged fine particle water containing radicals is attached to the obtained small items, and the odor components and allergen substances adhering to the small items are effectively decomposed or suppressed. In this case, for example, since the volume of the purification box 5 is much smaller than the volume in the passenger compartment 8, if charged fine particle water is discharged into the purification box 5, the charged fine particle water is high in the purification box 5. Therefore, the charged fine particle water can be intensively deodorized, sterilized, and inactivated allergen substances in a high concentration environment.

  Here, when the small article is made of fiber, the nanometer-size charged fine particle water penetrates deep inside the fiber due to the permeability of the nanometer-size water and effectively decomposes or suppresses odor components and allergen substances accumulated inside the fiber. can do.

When it is detected that an object is inside, the control unit 41 may control the power switch 40 provided in the power circuit of the electrostatic atomizer 6 to be turned on. In this way, when there are no small objects to be purified in the purification box 5, the electrostatic atomizer 6 is operated to discharge charged fine particle water into the purification box 5 unnecessarily. This saves energy and saves energy. As the detection means 13, a weight sensor or an object sensor using ultrasonic waves, light, electromagnetic waves, or the like can be used.
