Abstract
An electric automatic-drip coffee maker has a valve at a bottom of a water reservoir. In use, at turn ON, the valve remains initially closed so that a heater can heat up in a dry condition. When the valve is opened, steam is initially supplied to a brew basket and thereafter hot water is dripped into the brew basket in conventional fashion. The heater also supplies steam separately and continuously to a top of a carafe during brewing. A water supply for supplying this steam is drawn from the reservoir through a restricted outlet. The steam initially heats up the carafe and thereafter keeps the carafe warm.
