Abstract (en)

[origin: EP1940200A1] The oven (1) has a wave chain provided with a magnetron (4) and a power supply for powering the magnetron, where the wave chain supplies electromagnetic waves to a cavity (2) of the oven through a waveguide (3). The cavity is connected to the waveguide by openings (6, 8) forming a wave outlet (21), which couples the cavity and the waveguide, where the cavity has a ring (9) and a base wall (10). The cavity and the waveguide are made of identical enamel material e.g. decarburized steel, where inner walls of the waveguide are coated with a deposit of non-ferrous metal e.g. nickel. An independent claim is also included for a method for manufacturing a microwave oven.
