Description

  The present invention relates to an electrostatic atomizer that generates charged fine particle water using an electrostatic atomization phenomenon.

  Conventionally, tap water or the like is stored in a tank, the water stored in the tank is transferred by a water transfer unit, and a high voltage is applied to the water transferred by the water transfer unit, so that water is collected at the tip of the water transfer unit. Patent Document 1 discloses an electrostatic atomizer that electrostatically atomizes water to generate charged fine particle water.

However, the conventional electrostatic atomizer as shown in the above-mentioned Patent Document 1 is used for storing water such as tap water in a water tank and using this to electrostatically atomize, There is a problem in that a person needs to continuously replenish water in the water tank, which is troublesome to replenish water. In the above electrostatic atomizer, when the water to be supplied to the water tank is water containing impurities such as Ca and Mg such as tap water, the impurities react with CO ₂ in the air. As a result, CaCO ₃ , MgO, or the like is deposited on the tip of the water transport section, which hinders stable generation of charged fine particle water.

  Therefore, it is not necessary to replenish water, and by connecting the base of the discharge electrode to the cooling part of the Peltier unit and cooling the discharge electrode, moisture in the air is generated as condensed water on the discharge electrode. There is also known an apparatus in which the condensed water generated on the discharge electrode is electrostatically atomized (see Patent Document 2).

The phenomenon in which the discharge electrode is cooled by using this Peltier unit to generate moisture in the air as condensed water is a phenomenon in which impurities such as Ca and Mg are deposited and deposited as CaCO ₃ or MgO like tap water. However, since a Peltier unit is used, there is a problem that the cost becomes high.
