Abstract

An automatic coffee brewing system for brewing coffee in a chamber and dispensing the brewed coffee into a container. The chamber is automatically flushed upon completion of the brewing cycle. A predetermined amount of coffee grinds is automatically inserted into the coffee brewing chamber through an open lid. The brewing chamber is then rotated until the lid is closed. Hot brewing water is then inserted into the chamber, while the lid is automatically locked to prevent leakage of the brewed coffee. The brewed coffee then is removed from the chamber. The chamber is then rotated to enable the coffee grounds to be flushed from the chamber. The chamber is then rotated into position for brewing another container of coffee. A conical-shaped filter in the chamber enables brewed coffee to pass through to an outlet and simultaneously, retains the grounds in the chamber. During the flush cycle, water is forced into the chamber and the coffee grounds are cleared from the filter. A sprayhead is positioned at the apex of the conical-shaped filter for directing water flow during the brewing and flushing cycles.
