ABSTRACT:
A central power supply device for an electric supply of a domestic appliance and an electronic control unit of the appliance is connected to an output side of an interference suppression filter. The aim is to integrate recurrent, standardized devices in such a way that components are not allocated functions that do not belong to their task domain. To achieve this, an automatically controlled network disconnection device is integrated, together with the interference suppression filter, into the phase conductor, or in addition into the neutral conductor. A power supply device for an electronic control logic circuit of the network disconnection device is connected to the input side of the network disconnection device and the control output of the control logic circuit is connected to the control input of the network disconnection device.
