    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.

    Abstract: A portable vaporizer including a base, a steam stack which includes a baffle and a cup for retaining a liquid, a vented collar, a steam cap and a boiling chamber. The boiling chamber includes a heating element adapted to vaporize a liquid received therein. The vapor exiting the boiling chamber rises through a plurality of openings in the vented collar and mixes with ambient air drawn in through a second set of openings, resulting in a temperature drop in the vapor. The mixture hits the baffle, thus breaking the fluid stream into smaller streams, resulting in a further reduction in the vapor temperature. Consequently, the vapor leaving the vaporizer is at a lower temperature than that discharged from the boiling chamber.

The housing includes an evaporation chamber in the shape of an inverted cup which has a steam outlet in its top and contains an electric heating element positioned a short distance above its open end. The evaporation chamber and the heating element are immersed in water contained in the water supply compartment. The neck of an inverted, removable, water container filled with water is placed into the water supply compartment and water fills the water supply compartment until its level reaches the lower rim of the water container's neck. The housing and the water container are displaceable from the base so as to provide access to the water supply compartment and the heating element to facilitate cleaning.

  • Patent number: 5220637
    Abstract: An apparatus and method for controllably generating smoke from a simulating smoke-generating fluid. A container holds a supply of simulating smoke-generating fluid. A generally vertically-disposed, hollow, elongated, tubular member having inside walls surmounts the container with a lowermost opening thereof in fluid communication with the container and an uppermost opening thereof capable of being placed in fluid communication with an area into which the smoke is to be introduced. Preferably, gas is moved into the tubular member at a portion thereof near the lowermost end and in a direction generally tangential to a radius of the inside walls such that the gas flows upwardly in a generally spiral-like manner.

  • Patent number: 5210818
    Abstract: A humidifier including a base defining a reservoir adapted to retain water to be evaporated and a cavity adapted to receive leakage; an evaporator for inducing evaporation of water retained by the reservoir; a tank removably supported by the base and having a bottom wall defining a discharge opening communicating with the reservoir and an inlet opening communicating with the cavity; and wall means surrounding the inlet opening and extending from the tank into the cavity. Liquid in the cavity produces a seal that prevents undesirable leakage from the inlet opening.

  • Patent number: 5189726
    Abstract: The apparatus comprises a boiler (2) provided with an electric resistance heating element (3) arranged to heat and vaporize water, a water reservoir (6) independent of the boiler and a pump (8) designed to transfer water from the reservoir to the boiler. In the boiler a predetermined amount of water substantially corresponding to 50% of the overall capacity of the boiler itself is kept constant, thereby maintaining the steam amount unaltered and making the steam use always immediate. A steam control valve connected to the boiler (2) is driven by a magnetic float switch (14) housed in the water reservoir (6) to stop the steam emission when the cold water reservoir (6) is empty.
