ABSTRACT:
An improved electric steam vaporizer having a container defining a liquid reservoir and a removable cover for the container. Two parallel electrodes depend into the liquid reservoir from a cap attached to the cover. The electrodes are attached to the cap by inserting into electrode-receiving openings formed in the cap, welding the conductor ends on a line cord to tabs which project through the cap, bending the tab to mechanically lock the electrodes to the cap and in one embodiment potting the tabs and line cord conductor ends with a sealing material. An electrode housing attached to the cap surrounds the electrodes to define an inner-boiling chamber, an outer water-filled insulating chamber, and a small volume annular surge chamber which surrounds the lower end of the boiling chamber. The surge chamber which has an opening into the boiling chamber and an open bottom communicating with the liquid reservoir, reduces hot water flow from the boiling chamber to the reservoir and cold water flow from the reservoir to the boiling chamber. Steam from the boiling chamber passes through a foam trapping intermediate chamber in the cap and is discharged from a steam outlet which extends through the cap and the cover.
