Abstract
A humidifier is disclosed having a fine control for the distribution of humidified air. The humidifier contains a multiplicity of air moving devices, e.g., fans, to enable large quantities of humidified air to be distributed in an area or conversely, only a small amount of humidified air to be distributed in the area to maintain the humidity level already achieved. The humidifier requires only the power necessary to achieve or maintain the level desired without excess use of power. Furthermore, the level of fan noise is substantially reduced.
Claims22
A humidifier comprising a water reservoir, a humidification system for converting water from the water reservoir into moist air within the humidifier, and at least two air moving devices mounted relative to the humidification system for transporting the moist air outside the humidifier, the at least two air moving devices being controlled by means providing staged operation from a low moist air transport to a high moist air transport or from a high moist air transport to a low moist air transport.
A humidifier comprising a water reservoir, a humidification system for converting water from the water reservoir into moist air within the humidifier, and at least two air moving devices mounted relative to the humidification system for transporting the moist air outside of the humidifier, and means for staged operation of one of the air moving devices to produce a low moist air output or all of the air moving devices to produce a high moist air output.
A method of transporting moist air from a humidification system into an area comprising the steps of:
- operating at least two air moving devices at high speed to attain rapid transport of moist air to a desired humidification level;
- and
- maintaining the desired humidification level by operating only one air moving device at a lower speed to transport moist air to maintain the desired humidification level.
A humidifier comprising a water reservoir, at least two floatable water wicking elements floating on water in the reservoir, and an extending and contracting closure for an air path affixed to the top of each wicking element, the upper portion of each closure encompassing an air moving device situated so as to draw moist air through the closure and expel the air from the humidifier, the at least two air moving devices being staged from high moist air transport to low moist air transport or low moist air transport to high moist air transport.
The method of transporting moist air from a humidification system within a humidifier to the atmosphere outside the humidifier comprising the steps of:
- operating at least two air moving devices to transport air from within the humidifier to the outside atmosphere;
- and
- staging the air moving devices by operating the at least two air moving devices at a high moist air transport or by operating one air moving device at a low moist air transport.
A humidifier comprising a water reservoir and at least two fans situated side by side over the reservoir so as to draw moist air from the reservoir surface and to transport the moist air into the surrounding space, and means for staged operation of the multiple fans to provide from a very low moist air transport to a significantly high moist air transport or from a significantly high moist are transport to a very low moist air transport.
A room humidifier comprising a water reservoir, at least two floatable water wicking elements situated so as to float on water in the reservoir, and an extending and contracting closure for an air path affixed to the top of each wicking element, the upper portion of each closure encompassing a fan situated so as to draw moist air through the closure and expel the air from the humidifier.
A method of humidifying an area utilizing a humidifier comprising a water reservoir and at least two fans situated side by side over the reservoir so as to draw moist air from the reservoir surface and to transport the moist air into the surrounding space, the multiple fans being staged to provide from a very low moist air transport to a significantly high moist air transport or from a significantly high moist air transport to a very low moist air transport, the method comprising running at least two fans at relatively high speeds to attain rapid transport of moist air into an area and when the desired humidification level is reached maintaining the desired humidity level by running only one fan at a moderate speed to moderately transport moist air into the area.
