Abstract
A coffee brewing machine wherein a riser conveys heated liquid into the chamber of a liquid collecting receptacle above a filter holder containing a supply of flavoring agent, such as comminuted coffee beans. The bottom wall of the receptacle has one or more openings which admit heated liquid into the filter holder, and one or more apertures which discharge steam in such a way that the outflowing steam can or must bypass the filter holder. To this end, each aperture defines for steam a path which is inclined with reference to the bottom wall of the receptacle. An aperture can be provided in a hollow flow divider which is installed in the chamber to break up the flow of heated liquid from the riser toward the liquid discharging opening or openings. If the receptacle has a single aperture, the latter is preferably located in or at the central longitudinal vertical symmetry plane of the housing of the machine and causes the steam to leave the receptacle by flowing in such plane. If the receptacle has two apertures, they can be oriented in such a way that one aperture directs steam toward the front side and the other aperture directs steam toward the rear side of the housing.
