  • Patent number: 11596033
    Abstract: A hand protecting cavity ventilation system for an oven is provided. The system includes an air duct, positioned at a top of a cavity of the oven, the air duct having a duct outlet aimed toward a door to the cavity to provide an airflow along an inner surface of the door. The air duct extends downward from the ceiling of the cavity in front of and below a heating element disposed below the ceiling of the cavity. The air duct forms a vertically displaced hand protection portion to act as a barrier in front of the heating element, thereby guarding the heating element when the door of the oven is opened.

    Abstract: A reusable self-supporting field director useful for heating an article in a microwave oven is characterized by a plurality of vanes, each vane extending radially outwardly from a central axis and being angularly adjacent to two other vanes. The vanes are attached to each other at their inner ends. Each vane has a substrate formed from an electrically non-conductive material, and an electrically conductive sheath encasing the substrate so that a portion of the first and second major surfaces are covered by an electrically conductive material. The sheath is arranged on the substrate in a laterally symmetric fashion so that thermal expansion effects due to heating are equalized across the thickness of each vane.

  • Patent number: 8525087
    Abstract: Multi-purpose food preparation kits for foods which include dough, at least a portion of which is exposed for cooking, browning, and crisping, and optionally rising. The kits include a support base of susceptor material elevated above a support surface by an elevator member either incorporated with a base or separate therefrom. Kits further include a ring component of susceptor material which surrounds the food product, and which is dimensioned larger than the initial dimensions of the food product, so as to be spaced therefrom, at least initially, prior to cooking The space inside the ring component allows the dough to rise during cooking without obstruction by the susceptor ring and without imparting thermal energy from the susceptor ring to the dough surface. In one embodiment the susceptor base it provided in the form of a shipping carton.

  • Patent number: 8497455
    Abstract: A microwave oven cooking container is provided for evenly cooking foodstuff without risk of sparking during cooking. The container includes at least one compartment, and has at least two separate shields disposed on the container. A first shield is made of a material substantially opaque to microwave energy and is disposed on an outer or an inner surface of the compartment, with a shape generally corresponding to the outer shape of the compartment and optionally having an aperture on the base. The container further includes a lidding configured to seal the container closed, the lidding having a second shield disposed on the lidding, such as at a predetermined distance from the container sidewalls. Further, a multi-compartment container is configured to provide shielding for a food having a low specific heat capacity with one or more compartments arranged around and at least partially surrounding a shielded central compartment for the food.

The vanes are supported in a slotted central support member. Each vane has a predetermined thickness dimension. Each vane comprises a substrate formed from an electrically non-conductive material having a predetermined coefficient of thermal expansion and an electrically conductive wrapper having a predetermined coefficient of thermal expansion that is different from the coefficient of thermal expansion of the substrate. The wrapper wraps the substrate so that a portion of the first and second major surfaces are covered and the radially inner end of each vane is wrapped by an electrically conductive material. The wrapper and the substrate are arranged in a laterally symmetric fashion so that thermal expansion effects due to heating are equalized across the thickness of each vane.
