摘要： The invention provides a coffee machine, with a housing, a fresh water supply reservoir mounted therein, a heating means adapted to heat the fresh water and a feeding pump to supply the heated fresh water to a brewing chamber under pressure. The brewing chamber comprises a closure means and an inlet for coffee powder as well as an outlet for coffee. If appropriate, an installation for pushing out and removing, respectively, the leached-out coffee powder out of the brewing chamber and from the brewing chamber, respectively, may be provided. All parts of the apparatus which are subjected to contamination by the coffee powder or by the coffee, namely the brewing chamber, the closure element, the coffee powder inlet, the coffee outlet and eventually the installation for pushing-out and removing the coffee powder, are combined to a modular unit, which is removably inserted into the housing of the apparatus. The remaining parts, particularly the water reservoir, the heater and the pump as well as the required driving, control and operating elements are fixedly installed in the housing and are adapted to be operatively coupled to the modular unit upon insertion thereof into the housing. Thereby the contaminated parts can be cleaned easily and without danger, since the modular unit can be pulled out of the apparatus and rinsed as a whole.

摘要： The present disclosure includes an extraction assembly for use in an automatic espresso brewer. The extraction assembly includes components and methods for controllably extracting espresso beverage from a quantity of brewing substance. The components, assemblies, and methods facilitate improved control and operation of the extraction assembly and improve the reliability of the extraction assembly. The brewing substance is compacted between a pair of opposing pistons. Compacting force is monitored through at least one sensor carried on the extraction assembly to provide a signal to a controller. A predetermined compacting force may be programmed into the system for all brewing cycles or dependent upon the brewing substance used. The pair of pistons operates relative to a brew chamber for use in the espresso extraction process. The pistons provide compacting force and boundaries within the chamber and facilitate removal of a spent brewing substance puck at the end of the brewing cycle. Compacting force is monitored at the start of the brewing process and a predetermined force is required before the brewing process can be started. During the brewing process compacting force can be maintained and controllably adjusted. A variety of sensor methods and locations can be used to detect and monitoring compacting force.

摘要： A brewing facility for a coffee machine comprises a brewing cylinder (6) and an upper plunger (3) and a lower plunger (4) by means of which a brewing chamber is formed. The brewing cylinder (6) and the plungers (3 and 4) are held in a frame (2) such that they can be shifted, and can be driven by means of a driving facility. For adding the coffee powder, a coffee powder feed facility is provided which in turn is provided with a swivel-type funnel (14), which can be moved against a spring force from a filling position into a swiveled-away position, and vice versa. The swivel-type funnel (14) can be swiveled further from the swiveled-away position to a fully swiveled-out position and, in said fully swiveled-out position, can be locked by locking means (29) and unlocked by unlocking means (30). In this way, the swivel-type funnel (14) can be held in the fully swiveled-out position during the cleaning of, in particular, the upper plunger (3).
