Abstract
An automatic drip coffeemaker includes a removable, top mounted reservoir which delivers water in accurately controlled quantities to a small water tank. From the tank, the water flows through a tube to a heater well in which it is heated to boiling, thereby causing it to overflow the well. The hot water then flows a short distance to a spout located above a basket and spreader assembly through which it passes prior to entering a carafe which is heated by a warming plate. A control circuit serves to control the brewing and heating cycle. The water heating system also finds application for other purposes such as heating liquids for tea or soup.
