  In the inventions of Patent Documents 1 and 2, the bactericidal component eluted in water has a charge, and the surface of the submerged portion of the device member has a charge opposite in polarity to the bactericidal component. In this case, since the bactericidal component is adsorbed by the apparatus member and removed from the water, the concentration of the bactericidal component in the water is lowered, and the effect of suppressing the growth of microorganisms in the water is lost.

  The present invention has been made in order to solve the above-described problem, and by preventing the bactericidal component released in water from adhering to the surface of a submerged member or the like, the concentration of the bactericidal component in water is reduced. An object of the present invention is to provide a humidifying device that prevents the propagation of microorganisms in water.

Continuous humidifier according to the present invention includes a water tank for storing water, is partially immersed in the water of the water tank, a vaporizing humidification element by laminating disc-shaped or hollow disk-like substrate, the vaporized humidifier element A drive mechanism that rotates in an automatic or intermittent or forward / reverse direction, a blower that is provided at the top of the water tank and that discharges the wind that has flowed in from the inlet, and is provided in the water tank. A sterilizing component releasing portion that releases sterilizing components to suppress the growth of microorganisms, and the vaporizing and humidifying element holds water on the surface of the portion pulled up from the water of the water tank by the drive mechanism, The blower evaporates water held on the surface of the vaporizing / humidifying element by blowing from the inflow port, discharges the humidified air from the discharge port , and sterilizes the portion in contact with the water in the water tank. Ingredient release All or part of the portion except for the parts, it is charged to the same polarity as the biocidal component, and a substance which does not function as biocidal component is one that is applied or included.

  According to the humidifier according to the present invention, since the bactericidal component (substance) released in water can be prevented from adhering to the wetted part and the submerged member, the concentration of the bactericidal component in water decreases over a long period of time. Since this can prevent the growth of microorganisms in water, clean humid air can be obtained.
