Abstract
A coffee maker includes a housing and a brewing assembly. Pushing a handle leftward moves projections along slides in a direction for rising a cylindrical member until being stopped. A funnel-shaped member with a coffee bag placed therein can be slid along the rails toward the housing until being stopped. Pushing the handle rightward moves the projections in an opposite direction for lowering the cylindrical member until being stopped. The coffee bag is pressed by a clamping member and the funnel-shaped member. The coffee maker will supply hot water to an inflow opening such that hot water may then fall through a recess, a mesh element, and a cavity to pass through the coffee bag and proceeds to form coffee extract. The coffee extract may pass an outflow opening and a filter prior to flowing out of the coffee maker.
Claims9
A coffee maker comprising:
- a housing including a water reservoir, a heating device for heating water in the water reservoir, and a pump;
- and
- a brewing assembly comprising:
- an annular member in an upper front side of the housing and including a hingedly connected cover, a central channel, a side bottom rail, and a pair of bores at both sides;
- a movable cylindrical member under the annular member and including a top riser section having a plurality of first holes and a plurality of apertures, a plurality of L-shaped positioning members fastened in the plurality of apertures and each having a downward bar inserted through one of the pair of bores of the annular member, and a plurality of peripheral curved slides;
- an annular rotation member sleeved on an upper portion of the movable cylindrical member and including a plurality of equally spaced projections on an inner surface, the projections being adapted to be embedded in the plurality of peripheral curved slides, and a handle provided on an outer surface, the handle being moved leftwardly or rightwardly to rise or lower the movable cylindrical member by the co-action of the plurality of projections and the plurality of peripheral curved slides;
- a clamping member including a plurality of upper posts equally spaced around a top periphery with springs put thereon, the upper posts being inserted into the plurality of first holes, a plurality of walls equally spaced around the top periphery with each post disposed between two adjacent walls, the walls being engaged with the top riser section, and a central inflow opening in fluid communication with the pump;
- a holder including a central cavity, an overflow orifice proximate the annular member for receiving coffee bags and a bottom outflow opening on a center of the central cavity;
- and
- a funnel-shaped member adapted to slide along the bottom rail for positioning and including a bottom outlet opening and a front tongue.
