A microwave oven includes a muffle that includes a plurality of walls and defines an internal cavity for housing food, a radiofrequency supplying assembly that is configured to generate and propagate radiofrequency waves into the internal cavity via an access opening provided on one of the plurality of walls of the muffle, and a mounting flange arranged on an outer side of the muffle in correspondence to the access opening and configured to establish a coupling with the waveguide of the radiofrequency supplying assembly. The radiofrequency supplying assembly includes a radiofrequency generator, and a waveguide coupled to the radiofrequency generator and configured to guide the radiofrequency waves from the radiofrequency generator to the internal cavity.

It is the object of the present invention to present a coffee roaster, comprising: a resonant cavity, a heating unit, comprising: (i) at least one microwave oscillator and (ii) at least one beam-steerer, a sensing unit; and a control unit configured to control the microwave oscillator and the bean-steerer and receive data from the sensing unit.

In a method for detecting a standstill of a rotatable microwave distribution apparatus of a household microwave appliance, while microwaves are being supplied into a cooking compartment of the household microwave appliance, a microwave leakage radiation for angle-dependent recurring fluctuations is monitored and an action in the absence of such fluctuations being detected.

A heating cooking apparatus includes a heating cooking chamber (100A), a microwave supply unit (15), and a first heater (161). The heating cooking chamber (100A) includes an accommodation space (EA) that accommodates an object to be heated. The microwave supply unit (15) includes a radiation port (15C) and supplies microwaves (M1) from the radiation port (15C) to the heating cooking chamber (100A). The first heater (161) is positioned in the heating cooking chamber (100A) and heats the object to be heated. The first heater (161) and the radiation port (15C) are positioned in a predetermined direction (D1) with respect to the accommodation space (EA).

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.

The present application firstly discloses a cooking system comprising two cooking apparatuses, each capable of producing a cooked food from food or food ingredient(s). The first cooking apparatus comprises a plurality of microwave ovens which can be moved by an intermittent motion mechanism or a transport system. The second cooking apparatus comprises a cookware and a motion mechanism to move the cookware to dispense a cooked food to a food container. A semi-cooked food is produced by a microwave oven of the first cooking apparatus and is used as an ingredient in the second cooking apparatus to produce cooked food.

A stirrer shaft for a microwave oven includes a shaft body configured to connect between a stirrer motor on a first end of the shaft body, and a set of stirrer blades spaced apart from the stirrer motor. The stirrer body includes a flow passage therethrough for equalizing pressure in a sealed stirrer cavity of the microwave oven.

In a method for operating a household microwave appliance, a microwave treatment operation is controlled as a function of a temperature of a microwave generator. The household microwave appliance includes a cooking chamber, a microwave generator for routing microwaves to the cooking chamber, a temperature-determining apparatus for determining a temperature of the microwave generator, a microwave distribution device designed to change a field distribution in the cooking chamber during a microwave treatment operation, and a control device designed to control the microwave treatment operation as a function of the temperature of the microwave generator effected by a change in the field distribution.

A stirrer shaft for a microwave oven includes a shaft body configured to connect between a stirrer motor on a first end of the shaft body, and a set of stirrer blades spaced apart from the stirrer motor. The stirrer body includes a flow passage therethrough for equalizing pressure in a sealed stirrer cavity of the microwave oven.

A cooking apparatus includes a cooking chamber, a heating source disposed below the cooking chamber to produce high-frequency waves, a main plate forming at least a portion of the cooking chamber and including a front side which is opened, a front plate coupled to the front side of the main plate and including a base having an opening connected to the cooking chamber, and a front coupling flange. The front coupling flange is bent rearward from an inner end of the base, coupled by curling with the main plate, and has a portion which protrudes above a lower surface of the main plate.
