ABSTRACT:
A humidifier has an improved bottle wherein a continuously open drain outlet is located at the lower extremity of the bottle, a drain pipe being connected to the drain outlet and extending up the side of the bottle such that the upper end of the drain pipe establishes the static water level in the humidifier chamber. Electrodes extend vertically within the chamber such that current passes between the electrodes, via water in the chamber, to heat the water. The impurity level of the water in the chamber is monitored and when the impurity level reaches a predetermined value the chamber is flushed by opening a water inlet valve for a period of time. An electrical contact is provided to detect a high water level and when the water level drops below the high water level such that the contact continuously senses the absence of water for a fixed period of time, the inlet valve is opened until the high water level contact once again senses the water.
