Abstract
An electrostatically atomizing device comprises an emitter electrode, an opposed electrode, cooling means for condensing water on the emitter electrode, and a high voltage source; and high voltage is applied to the condensed water so that minute water particles are discharged from a discharge end at a tip of the emitter electrode. The device comprises a controller for causing the charged minute water particles to be discharged stably. The controller has an initial control mode and a normal control mode. In the initial mode, the cooling means is controlled so as to cool the emitter electrode at a predetermined cooling rate. Once discharge current reaches into a predetermined target discharge current range, the cooling means is controlled by feedback control, on the basis of the value of the discharge current, in such a manner that the discharge current is kept within the target discharge current range.
