Domestic appliance for processing foods

A domestic appliance for processing foods comprising housing structure, an electric motor and an electric accumulator in said housing structure, line terminal structure on said housing structure, charging terminal structure on said housing structure, a control switch on said housing structure,

• power pack structure having terminal structure for connection to an electric line cord, and an adapter body adapted to be mechanically connected to said housing structure, said adapter body including first and second terminal structures, said first terminal structure being electrically connected to said line terminal structure and said second terminal structure being electrically connected to said charging terminal structure when said power pack structure is mechanically connected to said housing structure,
• electrical circuitry including:
• a first circuit connecting said electric motor and said control switch with said line terminal structure,
• an electric switch, said electric switch having a first position connecting said electric accumulator in series circuit with said electric motor and said control switch for energizing said motor independent of said line terminal structure, and a second position connecting said electric accumulator in a second circuit with said charging terminal structure for charging said accumulator separate from and independent of said control switch, said motor being connectable to said line terminal structure through said control switch in said first circuit for energizing said motor when said electric switch is in said second position, and
• interconnection structure in said adapter body and cooperating with said housing structure for causing said electric switch to be switched from said first position to said second position when said power pack adapter body is mechanically connected to said housing structure.
