Abstract
A humidifier including a steam generator with a container for water and an immersed heating module. The heating module has a spherical shape and is formed of a stainless steel outer surface and an aluminum inner body. Electrical heating coils are affixed to the aluminum body to heat the aluminum body and transfer heat through the stainless steel into water. The composite of the inner and outer bodies provides efficient heat transfer for boiling water. The stainless steel resists any permanent adherence of residue to the heating module during the boiling process. Steam from the boiling water transfers through a mixing stack to surrounding air in the humidifier.
