US Patent 10085592 Sequential broiling

Several embodiments include a cooking appliance/instrument (e.g., oven). The cooking instrument can draw an alternating current (AC) power and generate a maximum available power for a heating system of the cooking instrument via a power component that converts the drawn AC power. The cooking instrument can then directionally heat each of different zones in a cooking chamber of the cooking instrument in sequence using one or more heating elements of the heating system on at least one side of the cooking chamber such that each step in the sequence utilizes the maximum available power for the heating system.
