A disclosed computer-implemented method for heating an item in a chamber of an electronic oven towards a target state includes heating the item with a set of applications of energy to the chamber while the electronic oven is in a respective set of configurations. The set of applications of energy and respective set of configurations define a respective set of variable distributions of energy in the chamber. The method also includes sensing sensor data that defines a respective set of responses by the item to the set of applications of energy. The method also includes generating a plan to heat the item in the chamber. The plan is generated by a control system of the electronic oven and uses the sensor data.

Electronic oven with infrared evaluative control

This disclosure includes methods and systems that utilize energy absorption monitoring for intelligent electronic ovens with energy steering. One disclosed method for heating an item in an electronic oven includes introducing an application of energy into a heating chamber using an energy source coupled to an injection port, changing a distribution of the application of energy in the heating chamber by setting a configuration of the oven to a first configuration, and measuring an energy return from the heating chamber while the oven is in the first configuration. The measuring is conducted using a radio frequency directional power sensor. The method also includes determining that the energy return from the heating chamber exceeds a level, adjusting, in response to determining that the energy return exceeds the level, the configuration of the oven from the first configuration to an altered first configuration, and saving the altered first configuration in a memory.

Energy absorption monitoring for an intelligent electronic oven with energy steering

Method and systems for heating an item in a chamber where a first electromagnetic wave is applied to an array of variable reflectance elements and a corresponding array of variable impedance devices are disclosed. The corresponding array includes first and second variable impedance devices. The first wave is reflected from the array to the item when the first device has a first impedance value. The reflecting places a local maximum of energy at a first location on the item. An impedance of the first device is altered. A second electromagnetic wave is applied and reflected. The reflecting places the local maximum at a second location on the item. Altering the impedance of the first variable impedance device alters a reflectance of a first variable reflectance element in the array of variable reflectance elements.

Electronic oven with reflective energy steering

An electronic oven and associated methods for heating an item by controlling a distribution of microwave energy using a set of reflective elements are disclosed. The electronic oven can include a chamber, a microwave energy source coupled to an injection port in the chamber, a set of actuators connected to the set of reflective elements, and a controller that controls the set of actuators. The controller can reposition the set of reflective elements via the set of actuators, and stores instructions that independently cause a repositioning of each reflective element in the set of reflective elements using the set of actuators. The set of actuators and set of reflective elements are each sets of at least three units.

An electronic oven with a set of variable reflectance elements for controlling a distribution of heat in the electronic oven and associated methods are disclosed herein. The electronic oven includes a chamber, an energy source coupled to an injection port in the chamber, and a set of variable reflectance elements located in the chamber. In some of the disclosed approaches the variable reflectance elements are nonradiative. A control system of the electronic oven can be configured to alter the states of the variable reflectance elements to thereby alter and control the distribution of energy within the chamber.
