Abstract
Several embodiments include a cooking appliance/instrument (e.g., oven). The cooking appliance/instrument can include a cooking chamber, a support tray adapted to hold food in the cooking chamber; and a heating system comprised of at least a heating element. The heating system is adapted to emit waves according to a particular configuration such that the emitted waves is substantially transparent or substantially opaque to the support tray and thus enabling the cooking instrument to select what to heat.
Claims20
A method for operating an oven comprising:
- receiving, by a control system of the oven, an instruction to cook food in a cooking chamber of the oven according to a digital recipe;
- and
- varying, by the control system in accordance with the instruction, a peak wavelength emitted by a heating element of a heating system to specifically and directly target different absorption bands of, and transfer heat to, a support tray adapted to hold food in the cooking chamber, an envelope of the heating element, a specific type of edible material in the food, or any combination thereof;
- wherein the heating element is configurable to emit waves at different peak emission wavelengths;
- and
- wherein the envelope of the heating element has an absorption band that is at least partially different than an absorption band of a material of the support tray.
A method for operating a cooking instrument comprising:
- operating a heating system responsive to a control system, the heating system comprising a heating element configurable to emit waves at different peak emission wavelengths inside a cooking chamber of the cooking instrument, the different peak emission wavelengths including a first peak wavelength such that a support tray adapted to hold food in the cooking chamber is substantially opaque to the emitted waves, and a second peak wavelength such that the support tray is substantially transparent to waves emitted from the heating element;
- and
- selecting, by a control system of the cooking instrument, one of the different peak emission wavelengths and driving the heating element to emit at the selected one of the different peak emission wavelengths.
A method for operating a cooking instrument comprising:
- identifying, by a control system of the cooking instrument, a food profile associated with the food on a support tray in a cooking chamber of the cooking instrument, wherein the support tray has a first absorption band;
- receiving, by the control system, an instruction to cook the food in the cooking chamber according to a digital recipe;
- varying, by the control system and according to the digital recipe and the identified food profile, a peak wavelength to be emitted by a heating element to specifically and directly target different absorption bands of, and transfer energy to, the support tray, an envelope of the heating element, a specific type of edible material in the food, or any combination thereof;
- operating a heating system comprising the heating element, the heating element configurable to emit waves at different peak emission wavelengths, and comprising the envelope, wherein the envelope comprises a second absorption band different from the first absorption band.
