ABSTRACT:
A self-sterilizing humidifier for air to be breathed, of the type having endless porous media driven to be progressively immersed in a receptacle. Means are shown for periodically providing throughout the effective volume of water in the receptacle heated water at a temperature above about 180.degree. F while the media drive is actuated, the heated water being sufficient to progressively expose the media to bacteria-killing conditions. In one embodiment a heater chamber automatically discharges a charge of water heated above about 180.degree. F into the receptacle. In one such case a thermal actuator has sensitive parts exposed to water in both the heater chamber and the receptacle, the actuator releasing the charge when water in the receptacle lies below its sensitive part, and water in the heater chamber has reached or exceeds the selected high temperature. In another embodiment the heater element is in the receptacle and is periodically energized to maintain bacteria-killing conditions while the blower in the air flow path is de-energized to reduce evaporative cooling of the media and water during the sterilization interval.
