Abstract:
1. A microorganism-resistant humidifier, comprising: a first reservoir having a predetermined water capacity; a second reservoir; a blower adapted to blow a stream of air through the humidifier and out to an ambient atmosphere, such that the stream of air picks up water vapor from water that may be in the second reservoir; a valve adapted to feed a quickly-evaporable quantity of water from the first reservoir into the second reservoir, the quickly-evaporable quantity of water being substantially smaller than the water capacity of the first reservoir; and a dry-out mechanism adapted to shut off the valve upon a user command and to continue to run the blower until the quickly-evaporable quantity of water has evaporated to an extent effective to inhibit the growth of microorganisms in the second reservoir.
