Abstract
An electrode type steam vaporizer device is disclosed which includes a plurality of ferrite electrodes positioned in a water receptacle wherein AC voltage is applied to the electrodes thereby vaporizing water in the receptacle. Each of the ferrite electrodes is a sintered body made of a mixture of iron oxide and a divalent nickel oxide. The ferrite electrodes are contained in an electrode assembly located within the body of the water receptacle such that a pair of electrode terminals extend through the top wall of the receptacle. A cover having a power source connector receiving concavity in its surface is positioned on top on the water receptacle. The cover is rotatable between a first position where the concavity is in registry with the electrode terminals and a second position where the concavity is out of registry with the terminals. A power source connector is received in the concavity and is connectable with the electrode terminals only when the cover is in the first position. When the connector is attached to the device, the cover is trapped between the body of the water receptacle and the connector, thereby preventing the removal of the cover. Thus the receptacle may not be…
