<p>The machine (1) comprises a support structure (3), in which the following are provided: a refillable water reservoir (4); a boiler (6) provided with an electric heater (7, 8); a pump (9) for supplying a flow of water from the reservoir (4) to the boiler (6); a first electric connector (5) for connecting the machine (1) to an AC supply voltage source; a dispensing unit (35) which is connected to the boiler (6), for dispensing a flow of hot water and/or steam, and to which the following can be coupled: a dose-holder unit (36) for receiving a dose, pre-packaged or loose, of a substance for the preparation of a beverage; a unit (24) for controlling operation of the machine (1); and at least one operating device (25) which can be operated so as to activate preparation of a beverage. The support structure (2, 3) comprises a fixed part (2) and a movable part (3) which can be coupled and uncoupled to/from each other and are provided with respective cooperating means for providing electric and hydraulic connections (12, 16, 17; 13, 20, 21). When the movable part (3) is coupled to the fixed part (2), the machine (1) as a whole is capable of operating with water drawn from the reservoir (4) and using AC electric power. When the movable part (3) is uncoupled from the fixed part (2), this movable part (3) is capable of operating autonomously with water supplied to the boiler (6) via a water inlet means (32) and using DC electric power.</p> |
