Abstract
A control device and method provides control of at least one operating feature of a cooking device in response to measured smoke and/or gas produced by item(s) being cooked. The device and method may control the temperature and cooking time of the device, and may also shut off the device or provide a fire alarm.
Claims25
A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:
- a sensing chamber;
- a tube communicating the interior of said cooking device and the sensing chamber in order to convey a stream of ambient air and a stream of at least a portion of smoke and/or gas generated during cooking to the sensing chamber;
- a detector associated with said chamber in order to measure a parameter of the smoke and/or gas in the chamber during cooking, wherein said stream of ambient air is located between said detector and said stream of at least a portion of the smoke and/or gas in the chamber;
- and
- a controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter.
A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:
- a sensing chamber;
- a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of smoke generated during cooking to the sensing chamber;
- a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking;
- a controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter;
- and
- a valve interposed in said passageway for selectively establishing or terminating the communication between said oven interior and said chamber.
A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:
- a sensing chamber;
- a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of smoke generated during cooking to the sensing chamber;
- a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking;
- a controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter;
- said chamber presenting an oven gas inlet and an oven gas outlet whereby gas from said oven including said smoke passes through the sensing chamber;
- and
- said chamber further having an ambient gas inlet and an ambient gas outlet arranged so that a stream of ambient air passes through the sensing chamber during passage of said oven gas there through, said stream of ambient air passing between said detector and said oven gas.
A cooking device controlling assembly for use with a cooking device having interior and at least one item being cooked, said assembly comprising:
- a sensing chamber;
- a tube communicating the interior of said cooking device and the sensing chamber in order to convey a stream of ambient air and a stream of at least a portion of smoke and/or gas generated during cooking to the sensing chamber;
- a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking, wherein said stream of ambient air is located between said detector and said stream of at least a portion of the smoke and/or gas in the chamber;
- and
- a controller coupled with said detector and cooking device that controls at least one oven function in response to the measured parameter.
A cooking device controlling assembly for use with a cooking device having interior and at least one item being cooked, said assembly comprising:
- a sensing chamber;
- a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of at least one gas generated during cooking to the sensing chamber;
- a gas detector associated with said chamber in order to measure a parameter of the gas in the chamber during cooking;
- a controller coupled with said detector and cooking device that controls at least one oven function in response to the measured parameter;
- and
- a valve interposed in said passageway for selectively establishing or terminating the communication between said oven interior and said chamber.
A method of controlling a cooking device for cooking at least one item, said method comprising the steps of:
- using a detector to measure through a tube, a parameter of
- (a) at least a portion of smoke emitted by the item during cooking or (b) at least one gas emitted by the item during cooking;
- directing a stream of ambient air between said detector and said portion of smoke or said gas;
- and
- controlling at least one oven function in response to the measured parameter.
