Brüheinrichtung für eine Haushalts-Espressomaschine

摘要

The pressure-filter device (1) consists of a housing section (19) with a piston (25) which can be moved vertically thereinto. On the housing section (19) there is a filter carrier (2) which can rotate horizontally about the pivot axis (4) and is fitted with a filter (29) fillable with ground coffee (39). With the piston (25) lowered into the filter (29) (operative position), the latter forms therewith a pressure chamber (40) enclosing the ground coffee (39) into which the pressurised hot water is forced on the piston side via a line (20) and the prepared espresso beverage flows on the filter side through at least one outlet aperture (38). With the piston (25) raised, the filter carrier (2) with the filter (29) can be pivoted out of the operating region of the piston (25) about a vertical axis (4). Thus the pivoting range of the filter carrier (2) extends from its operative position to its filling position in which the filter (29) is accessible from outside. It is only in the operative position of the filter carrier (2) that the latter is secured in relation to the housing section (19) against vertical movement by supports (43, 42) formed on both the filter carrier (2) and the housing section (19). The system of the invention provides substantially easier handling of the filter (29) in that it is more easily filled with ground coffee (39) and emptied without the need for an operator to hold the filter carrier (2). At the same time, the filter carrier is held firmly in the housing section (19) axially in its operative position without any significant distorsions being caused to these components.
