ABSTRACT:
The invention is directed to a domestic appliance for processing foods, with a basic device (1) accommodating an electric switch (6) and an electric motor (5), as well as electrical connecting means (4) for connection to an electrical power supply. The basic device (1) includes an electric accumulator (7) for operation independently of the line. To accomplish ease of manipulation and a higher as well as consistent power when the domestic appliance is operated on the line, it is suggested that the basic device (1) be provided with an electric switching arrangement (8, 14) which, in a first switching position, provides for connection of the electric motor (5) to the accumulator (7) and which, in a second switching position, provides for connection of the electric motor (5) and the accumulator (7) to the power pack (3), that an electric line cord (4) connect the power pack (3) to an adapter body (2) adapted to be mechanically connected with the basic device (1), and that the mechanical connection between the basic device (1) and the adapter body (2) also cause the electric switching arrangement to be brought into its second switching position.
