1. A brewing chamber of a beverage-making machine, which is suitable for accommodating, and extracting the contents from, a portion capsule that is filled with pulverulent or liquid beverage base materials and comprises, in full or in part, electrically conductive material, the brewing chamber comprising:
a fixed, first chamber part having an opener for opening the portion capsule for beverage-discharge purposes and connected in fluid communication to a structure for an outflow of the beverage; and a second chamber part that is movable horizontally or vertically in relation to the first chamber part, is connected in fluid communication to an extraction-liquid-feeding extraction-liquid pump, and comprises a piercing member for opening the portion capsule and for introducing the extraction liquid into the portion capsule, the brewing chamber is opened for the portion capsule to be received and is closed for the portion capsule to have its contents extracted, the first chamber part and the second chamber part respectively comprising first and second electrically conductive contacts that are electrically insulated from one another and are the ends of an interrupted control circuit of a checking and control device, wherein the piercing member located in the second chamber part is the second electrical contact, and wherein when the portion capsule is located in the closed brewing chamber, the first electrical contact of the first chamber part and the second electrical contact of the second chamber part are in electrically conductive contact with the portion capsule at least in an electrically conductive zone of the portion capsule, and the control circuit of the checking and control device is closed. |
