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.
Claims31
A grill comprising:
- a platen;
- a heater box disposed in physical contact with one side of said platen, thereby defining a cooking area of said platen, wherein said cooking area has a central portion and a portion which is remote from said central portion;
- and
- a temperature sensor disposed to sense temperature of said central portion of said cooking area of said platen;
- a heater that is disposed in said heater box and that has a structure that provides maximum heat to said remote portion and minimal heat to said central portion such that during a pre-heat mode or a recovery mode said cooking area of said platen attains a substantially uniform temperature before said temperature sensor senses a set temperature, which ends said pre-heat mode or said recovery mode.
2 more elements
A grill comprising:
- a platen;
- a plurality of heater boxes disposed on one side of said platen in an arrangement that provides a plurality of heating zones for said platen;
- and
- separate heaters disposed in said heater boxes, wherein said heater boxes are configured to have minimal heat migration therebetween so that said heating zones are capable of independent heating control for operation separately or in any combination thereof, and wherein each of said heater boxes comprises an insulation liner to minimize heat transfer to a neighboring heater box.
