Abstract
A gas range has burner head which have temperature sensing devices as a portion of the burner heads. Upon reaching a predetermined temperature, the temperatures sensing devices reduces gas flow to a bypass amount until temperature drops below to at least the predetermined temperature. Lowering the temperature in a cooking utensil below a common ignition temperature, while still allowing boiling, is an objective of many embodiments.
Claims20
A gas cooking appliance comprising:
- a burner head receiving gas flow from a gas supply, said burner head having flame ports for directing a burning fuel/air mixture therefrom;
- a cooking article support surface located above the flame ports;
- a temperature sensor having an upper limit and a lower limit below the upper limit, said temperature sensor located within an outer perimeter of the cooking article support surface;
- a regulator receiving the gas flow from the gas supply and directing the gas flow toward the flame ports, said regulator actuated mechanically by the temperature sensor;
- said regulator having a normal flow configuration and a reduced flow configuration whereby the flow rate when in the reduced flow configuration is less than when in the normal flow configuration with the temperature sensor mechanically moving the regulator between the normal flow configuration and the reduced flow configuration;
- wherein if the upper limit is reached, the regulator transitions from the normal flow configuration to the reduced flow configuration and the regulator remains in the reduced flow configuration until the lower limit is reached when the regulator transitions to the normal flow configuration.

- and
- wherein if the upper limit is reached, the regulator transitions from the normal flow configuration to the reduced flow configuration and the regulator remains in the reduced flow configuration until the lower limit is reached when the regulator transitions to the normal flow configuration.

A gas range comprising:
- a burner head, receiving gas flow from a selectively regulated gas supply from a control valve of the range, said burner head having flame ports for directing a burning fuel/air mixture therefrom;
- a mechanical temperature sensor having an upper limit and a lower limit;
- a regulator receives the gas flow from the gas supply downstream of the control valve and directs the gas flow toward the flame ports, said regulator mechanically actuated by the temperature sensor;
- said regulator having a normal flow configuration and a bypass flow configuration whereby the flow rate when in the bypass flow configuration is less than when in the normal flow configuration with the temperature sensor mechanically moving the regulator between the normal flow configuration and the reduced flow configuration;
- wherein if the upper limit is reached, the regulator transitions from the normal flow configuration to the bypass flow configuration and the regulator remains in the bypass flow configuration until the lower limit is reached when the regulator transitions to the normal flow configuration.
