SAFETY DEVICE FOR ELECTRIC HOUSEHOLD APPLIANCES

摘要

The invention concerns an electric household appliance for processing foods comprising a main body (1) including an electric motor unit and its control means, at least a working accessory (2) comprising a tool (3) designed to be driven by said motor unit and a safety device including a first means housed in the appliance main body (1) and a second means connected to the accessory (2). The invention is characterised in that the first means is a transceiver (7) and the second means is a transponder (8), said transceiver and transponder being designed to be inductively coupled by a radiofrequency or microwave electromagnetic field when the accessory (2) is installed on the appliance body. Preferably, the transponder (8) connected to the accessory (2) comprises a power circuit derived from the electric power induced in the transponder antenna and additional safety means for deactivating said powering circuit.
