摘要： A brewing head of an espresso maker includes a housing, and a lower brewing head section fixedly attached to the housing. The lower brewing head section includes a pressure sealed brewing chamber, and a lifting piston forming a floor of the brewing chamber. The lifting piston has apertures therethrough. A water inlet is located beneath the floor of the brewing chamber. An apparatus for moving the lifting piston is provided. The brewing head further includes an upper brewing head section movable relative to the lower brewing head section. The upper brewing head section includes an upper brewing head housing, and a fill shaft. The fill shaft is in communication with the brewing chamber when the upper brewing head section is moved to a fill position. The upper brewing head section further includes a brewing piston positioned over the brewing chamber when the upper brewing head section is moved to a brewing position. The brewing piston includes a coffee outlet in communication with the brewing chamber when the upper brewing head section is in the brewing position. The upper brewing head section further includes an apparatus for plunging the brewing piston into the brewing chamber when the upper brewing head section is in the brewing position. Moreover, the upper brewing head section includes a clearing element immovably secured to the upper brewing head housing for clearing the brewing chamber of used ground espresso when the upper brewing head section is moved to a clearing position.

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.

摘要翻译： 本发明提供了一种咖啡机，其具有外壳，安装在其中的淡水供应储存器，适于加热淡水的加热装置和供给泵，以将加热的淡水供应到压力下的冲煮室。 酿造室包括封闭装置和用于咖啡粉的入口以及咖啡出口。 如果合适，可以提供分别将煮沸室和煮泡室分别从出水室中推出和移出的装置。 受咖啡粉或咖啡污染的设备的所有部分，即酿造室，封闭元件，咖啡粉入口，咖啡出口以及最终用于推出和移出咖啡粉的装置， 被组合到模块化单元，其可移除地插入设备的壳体中。 其余部分，特别是储水器，加热器和泵以及所需的驱动，控制和操作元件固定地安装在壳体中，并且适于在将其插入壳体中时可操作地联接到模块化单元。 因此，污染的部件可以容易地被清洁并且没有危险，因为模块化单元可以从设备中拉出并作为整体冲洗。

摘要： A coffee machine includes a grinding mill, a proportioning chamber arranged adjacent to the outlet of the grinding mill and a processing chamber, into which the coffee powder from the proportioning chamber is discharged. The coffee powder coming from the grinding mill is thrown into the proportioning chamber, which includes a pressure sensitive, elastically resilient wall element with a signal generator connected thereto. As soon as the proportioning chamber is filled with coffee powder, a dynamic pressure is built-up within the proportioning chamber due to the overpressure caused by the grinding mill, which forces the wall element to a displacement, whereby the signal generator is operated. Subsequently, on the one hand, the motor of the grinding mill is switched off and, on the other hand, a bottom wall part of the proportioning chamber is unlocked, whereby the milled product, assisted by the elastically resilient wall element, is discharged from the proportioning chamber.

摘要翻译： 咖啡机包括研磨机，与研磨机的出口相邻设置的配比腔室和来自配料腔的咖啡粉末排出的处理室。 来自研磨机的咖啡粉末被投入到配料室中，该配料室包括压力敏感的弹性弹性壁元件，其中连接有信号发生器。 一旦配料室装满了咖啡粉末，由于磨机造成的超压，在配比腔内积累动态压力，这迫使壁元件发生位移，从而使信号发生器运转。 接下来，一方面关闭研磨机的电动机，另一方面，分配室的底壁部分解锁，由弹性弹性壁元件辅助的铣削产品从 配比室。
