Title of Invention

A BREWING RECEPTACLE FOR A BEVERAGE MAKER

Abstract

A brewing receptacle for an apparatus for brewing a beverage such as coffee. The receptacle has a brewing chamber (13; 63; 113) having an entry passage and an exit passage for displacing water through the chamber (13; 63; 113) for brewing the beverage, a bottom (14; 64; 114) for supporting the particles (18; 118, 118') (18), and a discharge 5 opening (19; 69; 119) in the bottom (14; 64; 114) for discharging beverage liquid through the bottom (14; 64; 114). At least the bottom (14; 64; 114) is invertible between a first and a second operative position. The brewing chamber (13; 63; 113) has a first volume and a first shape when the bottom (14; 64; 114) is in said first position and at least a second volume or a second shape of the brewing chamber in said second position is different from the first volume or shape, respectively.

Full Text

A brewing a beverage maker comprising such a brewing receptacle The invention relates to a brewing receptacle according to the introductory portion of claim as well as to a set of parts to t foam unit, and to a beverage maker comprising such a brewing receptacle A brewing receptacle of the above type is known from United States patent 6,192,786. A lateral wall of the coffee receptacle and a bottom formed by a filter plate define the volume of the brewing chamber of the receptacle, so that portioning is substantially predetermined According to this document, the receptacle is intended for receiving ground coffee. For adapting the volume of the brewing chamber to different amounts of coffee granulate from which coffee is to be brewed, the filter plate is arranged such that it is displaceable stepwise relative to the lateral wall of the coffee receptacle into predetermined positions in axial direction of the coffee receptacle, each position resulting in a different internal height of the brewing chamber. To this end, an elevating means in the form of a cam element is rotatably arranged in the coffee receptacle and supports projections of the filter plate in circumferentially distributed positions. A rotational movement of the cam element is capable of adjusting the position in which the filter plate is held by the cam element. The cam element is arranged in the coffee receptacle. With the volume of the brewing chamber, also the shape of the dumber is changed, since the depth is reduced while the diameter remains the same A problem of such a coffee receptacle is that the rotatable cam element in die coffee receptacle ferns an additional element, and that the structure designed to operate the cam element inside the coffee receptacle is relatively complicated and therefore costly. It is aa object of the present invention to provide a simpler solution that allows to change die volume and/or the shape of die brewing chamber in which particles from which a beverage is to be brewed are accommodated in a configuration of a particular shape.
