摘要： A microwave heating device includes at least two radiating portions that are adapted to radiate microwaves to the heating chamber and can be operated according to a plurality of operational configurations that differ in frequency and/or in phase shift(s) between the radiated microwaves. Data of energy efficiency, as a function of operational configurations, can be obtained for a product in the heating chamber. For example, energy efficiency data are obtained through a learning procedure. The obtained data can be processed to select one or more operational configurations ranking high in energy efficiency and a heating procedure for the product inside the heating chamber can be executed by operating the at least two radiating portions according to the selected one or more operational configurations.

摘要： An RF choke for an oven having a door movable between an open position and a closed position to interface with an opening defined in a cooking chamber of the oven includes a base portion and a plurality of resonant elements formed in rows. The cooking chamber is defined at least in part by a top wall, a bottom wall, a first sidewall and a second sidewall. The RF choke is disposed at a portion of the door facing the cooking chamber when the door is in the closed position. The base portion is a metallic sheet and is disposed in a first plane substantially parallel to a second plane in which the door lies. The resonant elements are folded out of the first plane toward the door to define a top row of resonant elements, a bottom row of resonant elements, a first side row of resonant elements and a second side row of resonant elements, which are proximate to respective ones of the top wall, the bottom wall, the first sidewall and the second sidewall of the cooking chamber when the door is in the closed position. At least one of the rows is folded out of the first plane at a different angle relative to the first plane than other ones of the rows.

摘要： An oven may include a cooking chamber configured to receive a food product, an EM heating system configured to provide EM energy into the cooking chamber using solid state electronic components, and control electronics configured to control the EM heating system. The control electronics are configured to enable user selection of a cooking program associated with cooking the food product. The control electronics select a first algorithm to direct application of the EM energy to the food product. The control electronics perform a learning process to receive feedback on execution of the cooking program during execution of the cooking program according to the first algorithm. Responsive to detecting a trigger event during the learning process, the control electronics are configured to select a second algorithm that is different from the first algorithm to direct application of the EM energy to the food product during execution of the cooking program.

摘要： An oven may include an oven body having at least sides and a housing cover, a cooking chamber disposed within the oven body and being configured to receive a food product, an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product, and an internal air cooling system configured to move air through the oven body to cool the solid state electronic components. The solid state electronic components include power amplifier electronics and control electronics configured to control operation of the power amplifier electronics. The power amplifier electronics are at least partially covered by an internal electronics cover. A first insulating member is applied to a bottom surface of at least one of the housing cover or the internal electronics cover to inhibit condensation above the solid state electronic components.

摘要： An air circulation system includes an inlet filter support structure, a first side filter and a second side filter. The air circulation system is for an oven that has a cooking chamber configured to receive a food product and a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The air circulation system is configured to provide air for cooling the solid state electronic components. The inlet filter support structure enables cooling air for cooling the solid state electronic components to be drawn therein prior to circulation by a cooling fan. The first side filter is supported by the inlet filter support structure. The first side filter is disposed below one of the sidewalls and disposed at an angle relative to the one of the sidewalls. The second side filter is supported by the inlet filter support structure. The second side filter is disposed below an opposing one of the sidewalls and disposed at the angle relative to the opposing one of the sidewalls.

摘要： An oven includes a cooking chamber configured to receive a food product and an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The solid state electronic components include power amplifier electronics configured to provide a signal into the cooking chamber via a launcher assembly operably coupled to the cooking chamber via a waveguide assembly. An isolation assembly is provided between the launcher assembly and the power amplifier electronics. The power amplifier electronics are controlled at least in part based on an efficiency parameter determined from a forward power value and a reflected power value that are each measured after the isolation assembly.
