Description

Purifier {Humidifier}

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

In general, a humidifier is to change the humidity in the room, and includes a humidifier for supplying moisture to the room.

The humidifier as described above includes an ultrasonic humidifier, a heating type humidifier, a composite type humidifier, a vaporization type humidifier, and the like.

Ultrasonic humidifiers generate ultrasonic waves from the bottom of a container filled with water to split water into small particles and blow them out, and the steam coming out of the humidifier is cold water vapor.

A heated humidifier boils water in the humidifier and blows it out as steam, and the steam coming out of the humidifier is hot steam.

Combination humidifiers utilize the advantages of heating and ultrasonic methods by applying ultrasonic and heating methods in combination. First, the water temperature is raised in a heating tube to sterilize, and then it is sprayed using ultrasonic waves. Depending on the situation, ‘warm steam’ ` You can choose 'cold steam'.

The evaporative humidifier may be a natural humidifier in which a blower fan may suck in external air and pass it through a humidifying filter, and the air may be atomized while passing through the humidifying filter and then discharged to the outside. The vaporization type humidifier may be a humidifying purifier that can filter foreign substances in the air as the air passes through the humidifying filter, and has both humidification and cleaning functions.
