Abstract
A cooking vessel includes a cooking surface and a lower portion positioned below the cooking surface. A first material is disposed within the lower portion and is in thermal proximity to the cooking surface. The first material increases in temperature upon absorption of electromagnetic radiation. A second material is disposed within the lower portion and in thermal proximity to the cooking surface. An electrical current is induced in the second material upon exposure to an electromagnetic field. Both the first material and the second material are configured to heat the cooking surface of the cooking vessel when used in a microwave oven or on an induction cooktop, respectively.
Claims16
A cooking vessel, comprising:
- a cooking surface;
- and
- a lower portion positioned below the cooking surface, wherein the lower portion includes discrete portions made of a magnetic field-absorbing material, which includes a ferrite component, and discrete portions made of a ferromagnetic material, wherein the discrete portions made of the magnetic field-absorbing material are positioned side-by-side with the discrete portions made of the ferromagnetic material, and wherein the magnetic field-absorbing material and the ferromagnetic material are different materials.
A cooking vessel, comprising:
- a cooking surface;
- a lower portion positioned below the cooking surface;
- a first material disposed within a first discrete zone of the lower portion and in thermal proximity to the cooking surface, wherein the first material increases in temperature upon absorption of electromagnetic radiation based on dielectric loss, and wherein the first material includes a rubber-embedded ferrite component;
- and
- a second material disposed within a second discrete zone of the lower portion and in thermal proximity to the cooking surface, wherein an electrical current is induced in the second material upon exposure to an electromagnetic field, wherein the first discrete zone is surrounded by the second discrete zone, and wherein the first material and the second material are different materials.
