Abstract
A coffee brewing appliance for making coffee by the percolation method in microwave ovens. The coffee maker is provided with a perforated metal enclosure with rounded edges to contain and protect the ground coffee particles from burning or charring which would otherwise be induced by microwave energy. The perforations are small enough to exclude microwave energy. The coffee maker is also provided with a housing which is microwave transmissive and which separates and insulates the metal portion from the microwave oven bottom and side walls. The housing and pump structures enhance the percolator pump action.
