An electric coffee maker includes a removable filtering member for receiving ground coffee beans. A selection unit can be actuated to operate the assembly of a water-supplying device, a flow control unit, and a dispensing member in a selected one of a single-stage Espresso coffee mode and a two-stag
An electric coffee maker includes a removable filtering member for receiving ground coffee beans. A selection unit can be actuated to operate the assembly of a water-supplying device, a flow control unit, and a dispensing member in a selected one of a single-stage Espresso coffee mode and a two-stage Americano coffee mode. In the Espresso coffee mode, hot water is supplied into the filtering member via a main water path for discharging brewed coffee. In the Americano coffee mode, hot water is supplied twice. The first supply of the hot water flows into the filtering member via the main water path so as to discharge brewed coffee into a cup. The second supply of the hot water flows into the cup via a secondary water path and a water passage space in the dispensing member that is located outside the filtering member.
