  • Patent number: 11457515
    Abstract: A cooking appliance, as provided herein, may include a cabinet, a magnetron, an induction heating coil, and a one-way field filter. The cabinet may define a cooking chamber. The magnetron may be mounted within the cabinet in communication with the cooking chamber to direct a microwave thereto. The induction heating coil may be mounted within the cabinet to direct a magnetic field thereto. The one-way field filter may be disposed within the cabinet between the induction heating coil and the cooking chamber to restrict passage of the microwave therethrough while permitting the magnetic field. The one-way filter may include a lower layer and an upper layer. The lower layer may include a plurality of parallel conductive bands extending in a first direction. The upper layer may be disposed above the lower layer. The upper layer may include a plurality of parallel conductive bands extending in the second direction.

  • Patent number: 10939510
    Abstract: A microwave oven includes a cabinet that defines a cooking chamber and a steam generator within the cooking chamber. The steam generator includes a disk-shaped main body with a water storage volume internal to the main body. The steam generator also includes a connector in operative communication with a motor of the microwave oven. The motor is operable to rotate the disk-shaped main body during a cooking operation of the microwave oven. The steam generator also includes a plurality of vents positioned above the water storage volume. The vents direct steam from the water storage volume into the cooking chamber of the microwave oven appliance during the cooking operation of the microwave oven appliance.
