Description

Humidifier {The Humidifier}

The present invention relates to a humidifier in which a part is immersed in a water tank receiving water from a water supply tank and mixed with water vapor and air vaporized in a vaporization filter that sucks up the water by capillary action and supplied to a room by a blower to perform humidification. .

Conventionally, the vaporization filter in this type of humidifier is formed by folding a single cloth member having good absorbency into a pleated box shape as shown in FIG. 9, or as shown in FIG. The cloth member is formed in a honeycomb manner. Moreover, rayon with good water absorption was used as a material of such a vaporization filter.

However, when rayon is absorbed, flexibility increases and elasticity is lost. Thus, it is difficult to secure a humidification amount because the vaporization filter collapses or the eye (space through which air passes) collapses.

Accordingly, an object of the present invention is to provide a humidifier having good water absorption, strong elasticity, and capable of securing a humidification amount in view of the above problems.
