ABSTRACT:
A gas humidifying device is disclosed which includes a generally enclosed chamber defining a water reservoir, and an umbrella-shaped member positioned in the chamber with its downwardly facing peripheral edge normally extending beneath the surface of the water in the reservoir, whereby the interior of said member defines a gas accumulation space in contact with the water surface. Gas inlet means are connected to the gas accumulation space for introducing a dry gas to be humidified; and gas outlet means are connected to the chamber, and communicate with the chamber which is external to the gas accumulation space within the unbrella-shaped member. At least portions of the peripheral edge of the umbrella-shaped member are upwardly displaceable from the normal position to a position above the water surface and such displacements intermittently occur as pressure builds up in the gas accumulation space in consequence of gas flow proceeding to such space from the inlet means. Such displacements of the member peripheral edge above the water surface enable intermittent flow of gas past the member edge, where intimate gas-water contact is effected, with the humidified gas then proceeding to the gas outlet means. The displacements of the peripheral edge also serve to agitate the water and surface thereof, which promotes uniformity of temperature of water in the reservoir--which reservoir may be provided with heating means to maintain the water temperature at an elevated temperature. The unbrella-shaped member can be mounted to be vertically displaceable as a unit; or the member can be constrained against unit movement, but possess sufficient flexibility to enable elastic upward displacement of the peripheral edge to a position above the water level, with the displacements of the periphery occurring uniformly or by sections.
