Abstract
A cooking appliance having a gas burner operable to generate a quantity of heat is disclosed. The cooking appliance also includes a pressure sensor operable to measure the pressure of gas supplied to the gas burner from a gas valve. The gas valve is programmed to adjust the supply of gas to the gas burner based on the measured pressure of the gas.
Claims15
A method of operating a cooking appliance, comprising:
- receiving a user-input signal corresponding to a user-desired quantity of heat to be delivered by a gas burner to a cooking surface,
- identifying a burner rating of the gas burner,
- setting a target pressure at which to supply gas to the gas burner based on the user-input signal and the burner rating,
- selecting an operation mode from a number of operation modes based on the target pressure, and
- operating a gas control system to supply gas to the gas burner in accordance with the selected operation mode, wherein operating the gas control system further comprising the steps of:
- supplying gas to the gas burner,
- igniting gas in the gas burner to produce a controlled flame,
- measuring the pressure of the gas supplied to the gas burner,
- suspending the supply of gas after a predefined time interval,
- determining an average quantity of heat delivered to the cooking surface during the predefined time interval based on the measured pressure of the gas and the burner rating, and
- calculating a duration for which the supply of gas is to be suspended.
