Description

Humidifier

The present invention relates to a purifier, and particularly to a purifier having a plurality of fans.

In general, a humidifier changes indoor humidity and includes a humidifying device that supplies moisture into the room.

Humidifiers as described above include ultrasonic humidifiers, heating humidifiers, combination humidifiers, and evaporative humidifiers.

An ultrasonic humidifier generates ultrasonic waves at the bottom of a water container to break water into small particles and emit them. The steam coming out of the humidifier is cold water vapor.

A heated humidifier boils the water in the humidifier and emits water vapor, and the steam coming out of the humidifier is hot steam.

The complex humidifier utilizes the advantages of both the heating and ultrasonic methods by applying a combination of ultrasonic and heating methods. It first raises the temperature of the water in the heating tube to sterilize it and then sprays it using ultrasonic waves. Depending on the situation, 'warm water vapor' is released. You can select ‘Cold Steam’.

An evaporative humidifier may be a natural humidifier in which a blowing fan can suck in external air and pass it through a humidifying filter, and the air can be atomized while passing through the humidifying filter and then discharged to the outside. An evaporative humidifier allows foreign substances in the air to be filtered by the humidifying filter as air passes through the humidifying filter, and may be a humidifying purifier that has both humidifying and cleaning functions.
