MICROWAVE OVEN AND METHOD FOR OPTIMIZING ITS DESIGN CHARACTERISTICS Russian patent published in 2005 - IPC

FIELD: microwave engineering; treatment of foodstuff, materials, and parts effectively using microwave energy.

SUBSTANCE: phase shifter as one of components designed for matching magnetron and foodstuff chamber is shown to possess greater functional capabilities when used in set of two parallel waveguides. Provision is also made for creating mode of operation in which minimal reflection from empty chamber is attained when the latter is selected according to proposed algorithm. Proposed design of microwave oven is distinguished by optimized characteristics for phase shifter and chamber. Variable easy-to-get-at phase shifter makes it possible to keep watch on cooking process. Method for optimizing design characteristics based on results of simulation is given in description of invention.

EFFECT: reduced cooking time, extended service life of oven handling comprehensive range of foodstuff.
