Humidifier {HUMIDIFIER}

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

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

Moisture absorbed in the humidifying filter is contained in the flowing air generated in the blowing section and is discharged into the indoor space.

However, since the humidification type filter according to the conventional art is fixed to the water tank, the immersion depth of the humidification filter (the length of the humidification filter immersed in the water stored in the water tank) varies depending on the water level of the water tank.

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

Further, when the immersion depth of the humidifying filter is large due to the high water level of the water tank, the natural vaporization type humidifier according to the prior art has a problem that excessive water is absorbed into the humidifying filter and the water is discharged in the form of water droplets .

Here, the driving unit is configured to transmit a rotational force in contact with a lower end of a rim of the filter frame, and the elevator unit can raise and lower the filter frame in a state where the rim of the filter frame and the driving unit are maintained in contact with each other.

For example, the driving unit may include a rotating body that transmits a rotating force in contact with a rim of the filter frame, and a driving motor that rotates the rotating body.
