Embodiment Construction

[0020] An embodiment of the present invention will now be described with reference to the accompanying drawings. figure 1 is a schematic diagram showing the electrostatic atomization device 4 . The electrostatic atomization device 4 includes a discharge electrode 1 , a liquid supply device 2 , and a high voltage application device 3 . The liquid supply device 2 supplies liquid to the discharge electrodes. The high voltage applying device 3 applies high voltage to the liquid supplied to the discharge electrode 1 .

[0021] figure 1 In the described embodiment, the liquid supply device 2 can be, for example, a cooling device. The cooling device cools the discharge electrodes so that moisture in the air condenses on the discharge electrodes 1 . This supplies water to the discharge electrode 1 . The cooling device, or liquid supply device 2 , comprises, for example, a Peltier unit 6 .

[0022] The Peltier unit 6 includes two Peltier circuit boards 10 and a plurality of therm...

Abstract

An electrostatic atomization apparatus (4) includes a discharge electrode (1) and a liquid supplying device (2), which supplies liquid to the discharge electrode. A high voltage application device (3) that applies high voltage to the discharge electrode and performs electrostatic atomization on the liquid supplied to the discharge electrode. A discharge optimization unit electrically coupled to the high voltage application device so that potential at the discharge electrode is such that electrostatic atomization is performed in an acyclic manner without stopping discharging.

Description

technical field [0001] The present invention relates to an electrostatic atomization device, which performs electrostatic atomization to generate charged water particles of nanometer size, and supplies the water particles to an atomization area. technical background [0002] The electrostatic atomization device cools the atomization electrode and condenses moisture in the air, thereby supplying condensed water to the atomization electrode. A high voltage power supply circuit applies high voltage to the condensed water supplied to the atomizing electrode. This results in electrostatic atomization that can generate charged water particles of nanometer size. Such an electrostatic atomization device is described in Japanese Patent Application Laid-Open No. 2005-131549. [0003] The electrostatic atomization device applies an initial voltage to the atomization electrode to start electrostatic atomization. When a voltage is applied to the electrostatic electrode, a Coulomb forc...
