Abstract
An apparatus for cooking food products on both sides which has a food-support surface that is transparent to both microwave and infrared radiation, an electric heating device, and a microwave generator. The microwave generator is connected to a waveguide cavity for irradiating the food products. The apparatus also has a food-contact heating surface that, together with the food-support surface, forms a cooking chamber capable of retaining the microwaves inside. The electric heating device has a shielded resistor with the external shield electrically connected to ground. The apparatus has a partition element made of thermal-insulating and microwave-transparent material, a portion of which is below the shielded resistor to separate the resistor from the microwave generator. The waveguide cavity has a microwave launch aperture underneath the partition element. The microwaves exit the cavity and pass through the partition element, the shielded resistor, and the food-support surface and radiate into the cooking chamber.
