Steam generator assembly and steam cooking appliances using same

A steam generator assembly for use in steam cooking appliances and which is capable of quickly generating a constant supply of steam having a high latent heat content, said steam generator assembly comprising:

• an electric heater device which includes a heater core defining a top end,
• first chamber means which defines a boiler chamber around said heater device and a head chamber above the boiler chamber, said head chamber including an end wall with discharge orifices therein,
• second chamber means defining a buffer chamber around said boiler chamber,
• water reservoir means defining a water chamber containing water,
• first inlet means for delivering water from said buffer chamber into said boiler chamber,
• first vent means for equalizing gas pressures above water levels in said boiler chamber and said buffer chamber and for enabling water from said buffer chamber to flow through said first inlet means from said buffer chamber into said boiler chamber, said first vent means being above said first inlet means, and
• means for providing communication between said water chamber and said buffer chamber for enabling water to flow from said water chamber to said buffer chamber and for enabling gas to pass from said buffer chamber into said water chamber to equalize gas pressures above water levels therein.
