Description

Humidifier {HUMIDIFIER}

The present invention relates to a humidifier, and more particularly, to a naturally evaporating humidifier having a humidifying filter immersed in a water tank.

In general, a natural vaporization type humidifier has a structure in which a lower part of a humidifying filter is immersed in a water tank storing water for humidification, so that the humidifying filter can absorb the water stored in the water tank.

The moisture absorbed by the humidification filter is included in the flowing air generated by the blower and discharged into the indoor space.

However, in the natural vaporization humidifier according to the prior art, since the humidifying filter is fixed in the water tank, the immersion depth of the humidifying filter (the length at which the humidifying filter is immersed in the water stored in the water tank) varies according to the water level of the water tank.

Such a natural vaporization type humidifier according to the prior art has a disadvantage in that it is difficult to implement a uniform humidification amount at the same air volume because the amount of water absorbed by the humidifying filter varies according to the immersion depth of the humidifying filter.

In addition, when the water level in the water tank is high and the immersion depth of the humidification filter is large, the natural vaporization type humidifier according to the prior art absorbs excess water in the humidification filter, and the water is discharged in the form of water droplets instead of being discharged in a vaporized state. there is
