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 cooking instrument comprising:
- a cooking chamber;
- a support tray adapted to hold food in the cooking chamber and having a first absorption band;
- a heating system comprised of:
- a heating element, the heating element configurable to emit waves at different peak emission wavelengths;
- and
- an envelope for the heating element, the envelope having a second absorption band different from the first absorption band;
- and
- a control system configured to:
- identify a food profile associated with the food on the support tray;
- receive an instruction to cook the food in the cooking chamber according to a digital recipe;
- and
- vary, according to the digital recipe and the identified food profile, a peak wavelength to be emitted by the heating element to specifically and directly transfer energy to the support tray, the envelope of the heating element, a specific type of edible material in the food, or any combination thereof.

A cooking instrument comprising:
- a cooking chamber;
- a support tray adapted to hold food in the cooking chamber;
- a heating system comprised of a heating element configurable to emit waves at different emission spectral distributions including:
- at a first emission spectral distribution such that the emitted waves disproportionally transfer energy directly to the support tray compared to directly to the food, and
- at a second emission spectral distribution such that the emitted waves disproportionally transfer energy directly to the food compared to directly to the support tray;
- and
- a control system configured to select one of the different emission spectral distributions and drive the heating element to emit at the selected one of the different emission spectral distributions.

A cooking instrument, comprising:
- a cooking chamber;
- a support tray adapted to hold food in the cooking chamber;
- a control system;
- and
- a heating system comprised of a first heating element and a second heating element, wherein the first heating element and the second heating element are each configurable to emit waves according to one of multiple spectral configurations selectable by the control system, wherein the multiple spectral configurations correspond respectively to whether one or more particular materials within the cooking chamber are substantially transparent or substantially opaque to the emitted waves, the particular materials including the support tray, and
- wherein the control system is configured to drive the heating system to sequentially power the first heating element then the second heating element or to drive the heating system to power both the first heating element and the second heating element.

A cooking instrument, comprising:
- a cooking chamber;
- a support tray adapted to hold food in the cooking chamber;
- a control system;
- and
- a heating system comprised of at least a heating element;
- wherein the control system is configured to control the heating system to generate first electromagnetic waves under a first spectral configuration targeting a first zone on the support tray and second electromagnetic waves under a second spectral configuration targeting a second zone on the support tray, wherein, under the first spectral configuration, the support tray is substantially transparent to the first electromagnetic waves and, under the second spectral configuration, the support tray is not substantially transparent to the second electromagnetic waves.
