  A counter electrode 19 is provided at a certain distance from the tip of the discharge unit 1 provided at the tip of the water transport unit 4. Further, a high voltage application plate 18 is connected to the water transport section 4, and the high voltage application plate 18 and the counter electrode 19 are connected to the high voltage application means 3 via high-voltage lead wires, respectively. A high voltage is applied between the water supplied from the voltage application means 3 to the discharge unit 1 and the counter electrode 19.

  In the electrostatic atomizer having the above configuration, when the thermoelectric elements of the Peltier module 13 are energized, heat is transferred in the same direction in each thermoelectric element, and the cooling part of the Peltier module 13 is cooled. The cooling plate 14 is cooled, whereby water in the air is cooled, and condensed water is generated on the surface of the cooling plate 14. Condensed water generated on the surface of the cooling plate 14 drops from the cooling plate 14 by gravity, and is supplied to the water receiving unit 5 provided on the discharge unit 1 side located below through the space 6. The water supplied to is supplied to the discharge unit 1.

  When water is supplied to the discharge unit 1 in this way and the high voltage applying means 3 applies a negative or positive high voltage of about 3 to 10 kV to the water supplied to the discharge unit 1, the discharge unit 1 holds it. The charged water is charged, the Coulomb force works on the charged water, the water level rises locally in a cone shape, and a Taylor cone is formed. The water at the tip of the Taylor Cone is high in density and repels the surface tension by receiving a large amount of energy (repulsive force of the high-density charge), and the water is repeatedly split and scattered (Rayleigh split) repeatedly. Electron atomization is performed, and nanometer-sized charged fine particle water containing active species (radicals) is generated. The nanometer-sized charged fine particle water moves toward the counter electrode 19 positioned opposite to the discharge unit 1 and is discharged to the outside of the electrostatic atomizer.

  Since this nanometer-sized charged fine particle water is extremely small as nanometer size, it floats in the air for a long time and has high diffusivity, so it floats to every corner of the atomization target space, The nanometer-sized charged fine particle water is present in such a way that the active species are encapsulated in water molecules, and thus deodorizing effect, mold and fungus sterilization and propagation In addition, the nanometer-sized charged fine particle water that exists in such a manner that the active species is encapsulated in water molecules has a longer life than the case where it exists as a free radical alone, so that the diffusibility, deodorizing effect, mold and The sterilization effect of bacteria and the suppression effect of reproduction will be further improved. In addition, since nanometer-sized charged fine particle water has a moisturizing effect, it has an effect of moisturizing.

  By the way, in this invention, since the water supply part 2 and the water receiving part 5 provided in the discharge part 1 side are made non-contact via the space 6, the discharge part 1 side and the water supply part 2 side are electrically connected. As a result, a high voltage applied for electrostatic atomization for generating charged fine particle water is not applied to the water supply unit 2 side. Trouble due to high voltage does not occur. Therefore, as in the above embodiment, in the case where the water supply unit 2 supplies water generated by condensation of moisture in the air using the Peltier module 13, the discharge unit 1 and the Peltier module 13 are used to prevent leakage. There is no need for insulation sealing. In addition, since the discharge unit 1 side and the water supply unit 2 side are not connected and are not in contact with each other, the degree of freedom of design for incorporating the device is possible and the device can be downsized.

  In each of the above embodiments, the water that was not received by the water receiver 5 among the water supplied from the water supply unit 2 is provided below the water receiver 5 with a recovery unit that recovers the water via a space. Here, it may be accumulated and dried by natural drying, or a drain may be provided and discharged.

The water supply unit 11 with the recovery part is attached to the attachment / detachment attachment part 33 in a detachable manner.

  In this way, the water is exchanged upside down and dripped again from the lower end of the supply pipe 22, and the dripped water is supplied to the water receiving unit 5 provided on the discharge unit 1 side located below through the space 6, and receives water. Water supplied to the unit 5 is supplied to the discharge unit 1, and a high voltage is applied to perform electrostatic atomization.

  In this way, two water supply units 11 with a recovery unit are prepared, water is supplied to the discharge unit 1 with one water supply unit 11 with a recovery unit, and surplus with another water supply unit 11 with a recovery unit. When water is collected and a certain amount of excess purified water is collected, the arrangement position can be changed to supply and collect water in the same manner as described above.

  Water is consumed by electrostatic atomization, but by reusing the water collected as described above, the time from the supply of water to the tank unit 26 to the next supply of water becomes longer.

  FIG. 15 shows another example of the valve 28. In this embodiment, a hole 36 is provided at the bottom of the tank portion 26, and the valve 28 is provided at the bottom of the tank portion 26 by a spring material 30 such as a torsion coil spring. The hole 36 is closed by the valve 28 by the elastic force of the spring member 30. When the hole 36 is fitted into the upper end of the supply pipe 22, the valve 28 is opened by rotating the valve 28 against the elastic force of the spring material 30 at the upper end of the supply pipe 22, The water in the tank portion 26 is supplied to the supply pipe 22.

  In the case where the water supply unit 2 is configured by the water tank 20, it is necessary to supply water to the water tank 20. As described above, the water supply unit 2 and the water receiving unit 5 are connected via the space 6. Therefore, the water tank 20 side and the side to which a high voltage is applied for electrostatic atomization are electrically disconnected, and as a result, electrostatic atomization is performed. Even during the operation of the device A, the water tank 20 can be replenished safely without stopping the operation of the electrostatic atomizer A. Moreover, since the discharge part 1 side and the water supply part 2 side are not connected, the freedom degree of an apparatus incorporation design is possible and the apparatus can be reduced in size.
