Latest Patents
One of her latest patents is a microwave delivery system for a cooking appliance. This system includes a toroidal waveguide, a launching zone, and a waveguide cover. The launching zone is designed with opposing walls that create a pathway for microwave energy to travel from a magnetron into the cooking chamber. The bottom wall of the launching zone aligns with the waveguide's bottom surface, establishing a direct conducting surface for the microwave energy field. The waveguide cover protects the interior of the waveguide from cooking byproducts generated during the cooking process. It is made of a metallic conductor that enhances microwave energy distribution in the cooking chamber.
Another significant patent is for a rapid cook oven with a dual flow fan assembly. This convection oven is designed to cook food efficiently by breaking down thermal insulation layers while removing contaminants from the convection air flow. The oven features both microwave and convection cooking systems. The dual flow fan draws in air from the cooking chamber and fresh air from the surroundings. These air flows are combined in a mixing chamber and passed over a heating element before re-entering the cooking chamber, effectively reducing smoke and contaminants.
