ABSTRACT:
A control system for a humidifier having operative components housed within a casing. The casing includes an upper portion which is removable to provide access to the interior such that a refillable water supply bottle may be removed from, and placed into, the casing. A first control system senses depletion of the water within the water bottle and activates an indicator or disables operation of the humidifier. This first control system includes a spring biased switch which presses laterally against a side of the water bottle. When the weight of the water bottle has sufficiently decreased, due to dispensing of the water therefrom, the spring bias may overcome the weight of the bottle to tip it slightly laterally, enabling the switch. A second control system is an interlock which disables operation of the humidifier upon the casing being open. A finger element extends downward from the lid of the casing and engages against a switch mounted within the casing. When the lid is removed to inspect the interior, or remove and replace the water bottle, the finger is removed from abutment against the switch, which allows the switch to open.
