Description

Humidifier The present invention relates to a humidifier, and more specifically, to a humidifier that generates humidified air using sterilized water. A humidifier is a device that vaporizes water and emits humidified air with a high moisture content. Humidifiers can generate humidified air by vaporizing water through natural evaporation, heated evaporation, or ultrasonic vibration. Each evaporation method has its advantages and disadvantages. In the case of natural evaporation, there is a problem in that the user must frequently manage the humidification medium used. In the case of heated vaporization, safety accidents may occur if hot humidified air is discharged directly. In the case of vaporization by ultrasonic vibration, there are issues such as the humidified air not flowing actively into the indoor space due to the atomization of supplied water by ultrasonic vibration, the possibility of unpleasant humidified air flowing into the indoor space if unsterilized water is used for humidification, and the ultrasonic transducer being vulnerable to high temperatures. In addition, in the case of vaporization by ultrasonic vibration, there is a problem that water may splash upward due to the vibrations generated by the vibrator. This scattered water may generate noise as it falls. Korean registered patent KR 10-0158806 discloses a humidifier that humidifies water supplied from a water tank by heating and ultrasonic vibration. Even with this structure, noise may be generated as water scattered by the ultrasonic vibrator falls.
