Abstract

An oven is disclosed adapted to heat a food item of the type having a crust portion and a filler portion lying on the crust portion, characterized in that a first electrical heating member, adapted for substantially constant heating operation at a predetermined temperature, is stationed in the oven adjacent the crust portion, and a second heating member, having a greater thermal intensity than the first heating means and adapted for substantially brief heating operation at a temperature higher than the predetermined temperature, is stationed in the oven adjacent the filler portion.

Claims

1. An oven for heating the upper portion of a food item under intense heat and for heating the lower portion of the food item with less intense heat, said oven comprising a housing having upper and lower portions;

quartz rod heating means positioned at the upper portion of said housing, and energizable to heat to a relatively high temperature;

heating coil means positioned below said quartz rod heating means;

support means for holding a food item between said quartz rod heating means and said heating coil means;

thermostat means for controlling only the operation of said heating coil means, said thermostat means establishing a relatively low temperature in said heating coil means to heat the lower portion of the food item; and

timing means for controlling only the operation of said quartz rod heating means, said timing means being actuable to energize said quartz rod heating means after a preselected time period after the establishment of the relatively low temperature to heat the upper portion of the food item and to de-energize said quartz rod heating means a preselected time period later.

2. The oven of claim 1 in which said relatively low temperature is about 500°

F.

3. The oven of claim 1 in which said relatively high temperature is about 1000°

F.

4. The oven of claim 1 in which said support means comprises a conductive metal plate.
