Abstract
Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.
Claims20
A cooking instrument comprising:
- a cooking chamber;
- a heating system including at least a tunable heating element comprising a wavelength controllable tungsten filament assembly capable of emitting wireless energy into the cooking chamber;
- and
- a control system configured to:
- determine a food substance or a food cooking recipe comprising the food substance,
- generate, based on an identity of the food substance or the food cooking recipe, a heating sequence to drive the heating system, wherein the heating sequence includes a first instruction to emit at a peak emission wavelength corresponding to a first excitable wavelength of the food substance;
- and wherein the heating sequence includes a second instruction to adjust a spectral power distribution of the emitted wireless energy based on a trigger event,
- detect the trigger event specified by the heating sequence, and
- responsive to detecting the trigger event, configure the heating system to adjust the spectral power distribution of the emitted wireless energy from the tunable heating element to target a second excitable wavelength of the food substance and/or one or more materials in the cooking chamber, by generating a control signal to adjust modulation of the power provided to the tunable heating element.

A method of operating a cooking instrument, comprising:
- initiating, at a control system of the cooking instrument, a heating sequence to configure a heating system of the cooking instrument, the heating sequence comprising an instruction to emit at a peak emission wavelength corresponding to a first excitable wavelength of a food substance;
- receiving, at the control system, a timer signal or a sensor signal;
- detecting a trigger event from the timer signal or the sensor signal;
- responsive to detecting the trigger event, dynamically determining a control signal corresponding to at least one spectra-tunable heating element of the heating system comprising a wavelength controllable tungsten filament assembly;
- and
- driving the at least one spectra-tunable heating element based on the control signal to adjust a spectral power distribution of wireless energy emitted from the at least one spectra-tunable heating element to target a second excitable wavelength of the food substance and/or one or more materials in the cooking chamber, by adjusting a modulation of the power provided to the heating element.

A cooking instrument comprising:
- a cooking chamber;
- a heating system including multiple tunable heating elements comprising wavelength controllable tungsten filament assemblies capable of emitting wireless energy into the cooking chamber;
- and
- a control system configured to:
- determine a food substance or a food cooking recipe comprising the food substance,
- generate, based on an identity of the food substance or the food cooking recipe, a heating sequence to drive the heating system, wherein the heating sequence includes a first instruction to emit at a peak emission wavelength corresponding to a first excitable wavelength of the food substance, and wherein the heating sequence includes a second instruction to simultaneously adjust, based on a trigger event detectable by the control system, a plurality of spectral power distributions of wireless waves emitted respectively from the multiple heating elements in the heating system,
- detect the trigger event specified by the heating sequence, and
- responsive to detecting the trigger event, configure the heating system to adjust the spectral power distribution of the emitted wireless energy from one or more of the multiple tunable heating elements to target a second excitable wavelength of the food substance and/or one or more materials in the cooking chamber, by generating a control signal to adjust modulation of the power provided to the tunable heating elements.
