Abstract
A brewing apparatus for an electric coffee maker includes a sleeve unit and a plunger unit disposed horizontally and movably within a base. Firstly, when a large chamber is defined within the sleeve unit between the plunger unit and a water-feeding unit, ground coffee beans can be fed into the large chamber via an opening in the sleeve unit. Subsequently, when the sleeve unit and the plunger clamp the ground coffee beans, hot water can be fed into a small chamber defined within the sleeve unit between the plunger unit and the water-feeding unit, thereby resulting in consumed ground coffee and brewed coffee that exits from the plunger unit. Finally, when the sleeve unit is separated from the plunger unit, the consumed ground coffee drops from a space defined between the sleeve unit and the plunger unit.
