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.
An apparatus for the preparation of hot beverages, particularly of coffee, comprising a housing, in the interior of the housing of the apparatus being provided, fixedly mounted, a fresh water inlet or a fresh water reservoir, a heating element for heating the fresh water, means for transporting the heated fresh water under pressure, and exchangeably mounted, a plug-in module incorporating a brewing chamber including an associated closure element and a beverage outlet, a means for pushing out and for removing leached-out beverage powder and a first driving means for driving said closure element associated with said brewing chamber, a second driving means for driving said means for pushing out and removing the leached-out beverage powder and clutch means including a driving member connected to said driving means and a driven member mounted to said plug-in module and operatively connected to said first and second driving means cooperating with said driving member and said driven member to be non-positively connected to each other if said plug-in module is inserted into said housing of the apparatus.
An apparatus for the preparation of hot beverages, particularly of coffee, including a housing, at least one of a fresh water inlet and a fresh water supply reservoir, a heating means for heating fresh water, a brewing chamber, means to supply heated fresh water to said brewing chamber under pressure, said brewing chamber comprising a closure means and an inlet for beverage powder and an outlet for beverage, and further including means for pushing out and removing, leached-out beverage powder from said brewing chamber, including driving and control means for said heating means, said brewing chamber, said supply means, said closure means and said pushing out and removing means;
An apparatus for the preparation of hot beverages, particularly of coffee, including a housing, at least one of a fresh water inlet and a fresh water supply reservoir, a heating means adapted to heat the fresh water, a brewing chamber, means to supply the heated fresh water to said brewing chamber under pressure, said brewing chamber comprising a closure means and an inlet for beverage powder as well as an outlet for beverage, and further including means for pushing out and removing, leached-out beverage powder from the brewing chamber;
