The invention relates to a household appliance with an electric control system (20), which is connected to an accessory part (12) for the household appliance in a signal-transmitting fashion, wherein the accessory part (12) can be moved back and forth between an active position and a resting position on the household appliance and, in the switched-on state of the household appliance, exchanges signals for controlling the household appliance with the electric control system (20), at least in the active position.In order to specify a household appliance in which the accessory part, in its resting position, is stored in the household appliance in such a way that the user can access the household appliance without obstruction and, at the same time, a high degree of security against malfunction is guaranteed, the signal exchange between the transmission or transmission/reception device (17) of the accessory part (12) and the electric control system (20) occurs wirelessly and the accessory part (12), in its resting position, is mounted in a storage element (6) of the household appliance at least partly consisting of an electrically conductive material, said storage element electrically shielding the transmission or transmission/reception device (17) of the accessory part (12) from the electric control system (20) so that signal exchange is prevented.
