Induction cookware with bi-metallic smart susceptor

A cookware for use with an induction coil, the cookware comprising:

• a container configured to receive a material to be heated, wherein the container comprises a susceptor material;
• and
• a base layer positioned adjacent to the container, wherein:
• the container is magnetic at a room temperature and has a Curie temperature at which the container is non-magnetic;
• and
• the base layer is non-magnetic at the room temperature, an electrical conductor, a thermal conductor, and in thermal communication with the container.

An induction cooking system comprising:

• a cooktop comprising an induction coil configured to generate a electromagnetic field;
• and
• a cookware, comprising:
• a container configured to receive a material to be heated;
• and
• a bi-metallic assembly over a surface of the container and in thermal communication with the container, wherein:
• the bi-metallic assembly comprises a susceptor layer and a base layer positioned adjacent to the susceptor layer;
• the susceptor layer is magnetic at a room temperature and has a Curie temperature at which the susceptor layer is non-magnetic;
• the container is non-magnetic at the room temperature;
• and
• the base layer is non-magnetic at the room temperature, an electrical conductor, a thermal conductor, and in thermal communication with the susceptor layer.

A method for forming a cookware for use with an induction coil, the method comprising:

• forming a bi-metallic assembly comprising a susceptor layer and a base layer over a surface of a container, wherein:
• the container is configured to receive a material to be heated;
• the susceptor layer and the base layer are in thermal communication with the container;
• the susceptor layer is magnetic at a room temperature and has a Curie temperature at which the susceptor layer is non-magnetic;
• the base layer is non-magnetic at the room temperature, an electrical conductor, and a thermal conductor;
• and
• the container is non-magnetic at the room temperature.

A method for cooking, comprising:

• placing a material to be heated onto a cookware, the cookware comprising:
• a container configured to receive the material to be heated;
• and
• a bi-metallic assembly positioned over a surface of the container and in thermal communication with the container, the bi-metallic assembly comprising a base layer and a susceptor layer, wherein:
• the susceptor layer is magnetic at a room temperature and has a Curie temperature at which the susceptor layer is non-magnetic;
• the container is non-magnetic at the room temperature;
• and
• the base layer is non-magnetic at the room temperature, an electrical conductor, a thermal conductor, and in thermal communication with the susceptor layer;
• placing the cookware in proximity to an electromagnetic field;
• flowing, with the cookware in proximity to the electromagnetic field, an electric current through the susceptor layer and heating the susceptor layer toward a leveling temperature of the susceptor layer;
• transferring a flow of the electric current from the susceptor layer to the base layer thereby decreasing further heating of at least a portion of the susceptor layer and the container;
• and
• removing the material to be heated from the cookware.
