  • Patent number: 6938886
    Abstract: A humidifier including a steam generator with a container for water and an immersed heating module. The heating module has a spherical shape and is formed of a stainless steel outer surface and an aluminum inner body. Electrical heating coils are affixed to the aluminum body to heat the aluminum body and transfer heat through the stainless steel into water. The composite of the inner and outer bodies provides efficient heat transfer for boiling water. The stainless steel resists any permanent adherence of residue to the heating module during the boiling process. Steam from the boiling water transfers through a mixing stack to surrounding air in the humidifier.

  • Patent number: 6909840
    Abstract: The present invention relates to an apparatus and method for rapid flash-like volatilization of high and low vapor pressure components from liquid or solid emanators which is in contact with a point or localized heat source. Vaporization is promoted by a geometrically small electrically resistive heating element with variable activation for pulsed or cyclic heating of an emanating surface containing the volatile components. The apparatus is primarily directed towards the treatment of residential air for fragrancing, odor elimination, treatment of insects or pests, air sanitization, air and surface antibacterial or antimicrobial treatment, or other ambient air or surface modification by way of gas or vapor distribution.

  • Publication number: 20030206731
    Abstract: A portable warm air humidifier for delivery to a room a steam air mixture of uniform moisture and at a temperature that does not cause sensation of pain. A steam ejector is used to mix the steam from an evaporation chamber with the air entering the humidifier with the advantage, among others, of eliminating the need for motors and blowers. A difference in the water level between a water supply compartment and the evaporation chamber provides a constant pressure in the evaporation chamber which is necessary to drive generated steam through a steam nozzle communicating with the steam ejector. The dimensions of the steam nozzle are determined in relation with the rate of steam generation in accordance with steam velocity to effectively eliminate or minimize the noise normally associated with the passage of steam through a nozzle.
