ABSTRACT:
A portable and compact humidifier for use in a hotel room includes a vaporizing chamber having a heating element that vaporizes water contained in a hotel sink or ice bucket. Various safety devices are provided, all of which connect with a ground fault interrupt circuit ("GFCI") located at the electrical plug end of the humidifier. Upon the occurrence of a fault condition, the GFCI disconnects electricity from the vaporizing element. The safety devices include both high and low water level sensors, and a heating element overheat sensor. The humidifier enclosure may either comprise a single component that allows the entire humidifier to float in the reservoir, or the enclosure may comprise a plurality of enclosure sections that telescope relative to each other. The uppermost section is fixed in height with respect to the reservoir, while the lowermost section floats in the reservoir. As the level of water in the reservoir decreases, the telescoping enclosure increases in length.
