Problems solved by technology

Such devices, however, were characterized by difficulties in maintaining coffee flavor over time, in controlling waste as occurred by making excessive coffee that was then discarded, and in cleaning and maintenance of the coffee makers.
However, such machines are expensive and not economically attractive to most consumers even though they may make the best coffee.
Such systems are characterized by locating the brewing chamber at an inaccessible location so it becomes impossible or, at best, very difficult, to clean the brewing chamber

Embodiment Construction

[0050]FIG. 1 depicts one embodiment of an apparatus of this invention for brewing beverages, such as coffee, by supplying a heated liquid, such as hot water, under pressure to an infusible material in an infusion chamber. Specifically, FIG. 1 depicts such apparatus in the form of an espresso machine 20 with a housing 21 on a base 22. The housing 21 includes a cup warmer 23 for cups, such as the cup 24, so cups can be preheated before being filled with espresso. The housing includes a control panel 25, a brewing / steam control knob 26 and a grind fineness adjustment knob 27 for any included coffee grinder. A water reservoir or tank 30 on the base 22 has an integral handle 31 to facilitate removal and filling.

[0051]FIG. 1 depicts a removable, reusable, infusion chamber 32 at a brewing station 33 that includes a grounds cup holder 34 with an integral handle 35. A removable drip tray assembly 36 resting on the base 22 provides a facility for supporting one or two cups 37L or 37R or both...

Abstract

A brewing apparatus for infusing compacted ground coffee in a grounds cup at a brewing station with heated water under pressure. At a brewing station, a piston head with an active seal that is spaced from the grounds cup wall during motion, extends into the grounds cup. When the piston head begins to compact the ground coffee it activates the seal to form a sealed upper end of a brewing chamber. Hot water is admitted to the brewing chamber to produce the coffee. When the brewing cycle is completed, the piston head displaces further to force additional coffee from the grounds. Then the piston head retracts to allow the infusion chamber assembly to be removed for cleaning.

Description

FIELD OF THE INVENTION [0001] This invention generally relates to apparatus for brewing beverages by directing a liquid, such as hot water, across a compacted infusible material, such as ground coffee beans, in a sealed infusion chamber. DESCRIPTION OF RELATED ART [0002] A large number of commercial devices are available for brewing beverages, particularly coffee, by infusing material with a liquid. Prior art coffee makers have incorporated a variety of percolating, drip, steeping and other brewing approaches. A large number of these coffee makers were also designed to brew coffee in batches, for example, 4-cup to 12-cup batches. Such devices, however, were characterized by difficulties in maintaining coffee flavor over time, in controlling waste as occurred by making excessive coffee that was then discarded, and in cleaning and maintenance of the coffee makers. [0003] The advent of espresso machines introduced new coffee brewing concepts. Espresso machines produce a small quantity ...
