ABSTRACT:
An electric single-pass drip-type coffeemaker includes a plastic base having an upper half with an opening surrounded by a downward lip. A metal warming plate closes the opening and is laterally immobilized by downwardly projecting spaced bosses around the opening. A central upward protuberance on the lower half of the base terminates in a high temperature silicone pad which engages the underside of the warming plate and presses the plate up against a gasket seated in a groove in the lip to vertically immobilize the warming plate between the lip and the silicone pad when the upper and lower base halves are secured together. A U-shaped metallic extrusion is welded or soldered to the underside of the warming plate and includes an upper passage containing an electric heating element controlled by an adjustable thermostat secured to the extrusion and a lower water heating passage connected to the cold water reservoir and hot water discharge spout of the coffeemaker.
