ELECTROSTATIC ATOMIZER

摘要

An electrostatic atomizer having a discharge electrode, a counter electrode, a cooling source, a high voltage power supply, a current detector, and a controller. The cooling source cools the discharge electrode to form a water dew thereon. The power supply applies a high voltage for discharge between the electrodes. The detector detects a current flowing between the electrodes. The controller judges whether or not a discharge between the electrodes is a dry discharge, and the judgment is based on the current detected by the detector when the power supply applies a high voltage between the electrodes. The dry discharge is a discharge occurring when the quantity of dew on the discharge electrode is smaller than a specified quantity. When a discharge between the electrodes is the dry discharge, the controller temporarily raises cooling rate of the cooling source.
