Abstract

A system and method for induction cooking using an induction cooking unit, an interface adapted to receive, store, and execute a plurality of instructions of a multistage programmable recipe using the induction cooking unit, a power supply, a controller coupled to said power supply, said interface, and said induction cooking unit.

Claims

1. A method of induction cooking comprising the steps of:

providing a circular induction cooking unit comprising;

i. a heat-resistant top surface extending to an edge of the induction cooking unit,

ii. at least one induction electromagnetic coil located below the top surface,

iii. a fan,

iv. a vent,

v. an interface comprising an input panel having a plurality of non-numeric input buttons which allow a user to create multi-stage programmable recipes as user selected direct commands,

vi. memory for storing user selected direct commands, the input buttons including an execution button for executing a user selected direct command when activated,

vii. an electronic controller having a processor and electronically coupled to the induction electromagnetic coil, the fan, the memory and the interface, and

viii. a system housing supporting the heat-resistant top surface at a periphery, retaining the interface and enclosing the induction electromagnetic coil;

placing an induction cookware on the heat-resistant top surface of the circular induction cooking unit;

entering a multistage programmable recipe including at least one of either a temperature or a time, using the plurality of non-numeric input buttons to generate a first user selected direct command;

storing the first user selected direct command in memory coupled to the processor;

executing the first user selected direct command via the electronic controller;

electronically controlling the circular induction cooking unit in accordance with the first user selected direct command; and

ventilating the circular induction cooking unit using the vent and the fan.

2. The method of induction cooking of claim 1, wherein the plurality of non-numeric input buttons comprises at least one of:

a program button configure to receive a user selected direct command;

a time button configured to receive a user selected direct command;

a temperature level button;

an increase time or temperature button;

a decrease time or temperature button;

a start program button; and

a cancel program button.

3. The method of induction cooking of claim 1, further comprising the steps of sensing removal of the induction cookware from the top surface, and automatically turning the induction cooking unit off after a preset time.
