Problems solved by technology

These mechanisms have a number of disadvantages: the mechanism can be rendered inoperable relatively easily by less appreciative users; the mechanical elements can wear out and become inoperable; the mechanical elements are sensitive to contamination
In addition, the safety device is not absolute, because the sensor is maliciously blocked by using a cooperating magnet

Embodiment Construction

[0029] According to FIG. 1 , a domestic appliance is shown schematically, comprising a main body 1 enclosing a not shown motor unit and a control unit, a detachably mounted working attachment 2 equipped with a tool 3 , the tool 3 Driven by the motor group through the output shaft 4 of the motor group. In the case shown, the accessory comprises a hemispherical housing 5 equipped with a rotary tool 3 and closed by a cover 6 . But of course, the invention is not limited to household appliances using this type of accessory. For example, the accessory includes an elastic transfer device, the end of which can accommodate a variety of cleaning brushes, or kitchen preparation implements, such as whisks, mixers.

[0030] The appliance is equipped with a safety device consisting of two devices. The first means 7 indicated by broken lines are arranged in the main body 1 of the appliance and act on the control means of the motor unit, and the second means 8 indicated by broken lines are...

Abstract

An electric household appliance for processing foods comprises a main body including an electric motor unit and its control elements, at least a working accessory comprising a tool designed to be driven by the motor unit and a safety device including a first member housed in the appliance main body and a second member connected to the accessory. The member is a transceiver and the second member is a transponder, the transceiver and transponder being designed to be inductively coupled by a radiofrequency or microwave electromagnetic field when the accessory is installed on the appliance body. Preferably, the transponder connected to the accessory comprises a power circuit derived from the electric power induced in the transponder antenna and additional safety elements for deactivating the powering circuit.

Description

technical field [0001] The invention relates to a domestic appliance for processing food, comprising a body enclosing a motor unit and its control means, and a working accessory equipped with a tool intended to be driven by the motor unit. [0002] More specifically, the present invention relates to a safety device comprising a first means arranged in the body of the device and actuating the control means of the motor unit, and connected to the accessory for if A second means of preventing operation of the appliance if the accessory is not installed. Background technique [0003] In such appliances, the current solution for the safety device consists in implementing a mechanical device acting on an interrupting device arranged between the power supply of the device and the motor unit. These mechanisms have a number of disadvantages: the mechanism can be rendered unusable relatively easily by less appreciative users; the mechanical elements can wear out and become inoperable...
