ABSTRACT:
A vaporizer having an improved electrode-type steam generator structure to control the amount of steam generated and to maintain the power requirements for generating the steam constant. The generator is particularly adapted for portable room humidifiers where the steam is generated in a confined chamber within a large reservoir of water. The generator comprises a pair of concentric electrodes disposed in the bottom of the steam chamber. The surface areas of the electrodes are in spaced relationship and a perforate cap is placed over the electrodes or the radially outer electrode is an inverted cup-shaped member the end of which is perforated to determine the amount of steam which is allowed to escape off of the electrodes. A fan mixes the steam with air and the unit is provided with an electrical circuit to prevent shocksfrom the unit and to prevent operation without a properly wired and grounded outlet.
