Abstract
A grill having a platen with a plurality of heating zones. Each heating zone has a heating unit. Thermal transfer between adjacent heat zones is limited by air gaps and insulation. The heater unit of each zone has a heater that is disposed to attain substantially uniform temperature of the platen for that zone before a temperature sensor senses a set temperature during either pre-heat or recovery modes.
Claims13
A grill comprising:
- a grill surface;
- and
- a gas burner disposed to provide heat to said grill surface, wherein said gas burner comprises a surface in which an array of elongated ports is disposed in a row of first and second orthogonal orientations on an interleaved basis, wherein said array of elongated ports is arranged to provide more heat to a peripheral part of said grill surface than to a central part of said grill surface such that during a start up or a recovery mode a temperature of the heat provided to said central part does not reach a set temperature before a temperature of the heat provided to the peripheral part reaches said set temperature.
A grill comprising:
- a grill surface comprising a central part and a peripheral part;
- a heater disposed to provide heat to said grill surface;
- a temperature sensor disposed to sense a temperature of heat provided by said heater to said central part of said grill surface;
- and
- wherein said heater comprises a structure that provides more heat to said peripheral part than to said central part of said grill surface such that during a start up mode or a recovery mode the sensed temperature of the heat provided to said central part does not reach a set temperature before the heat provided to said peripheral part reaches the set temperature.
