Household appliance, in particular a household dishwashing machine

1. A household appliance, comprising:

an operating display unit having at least one visual and/or acoustic display configured to at least display and/or signal a completed treatment cycle;

an actuatable switching unit configured to activate and deactivate the household appliance, the switching unit being movable between a closed position directly connected to a main voltage supply and an open position disconnected from the main voltage supply;

an on switch configured to move between a closed position in direct connection with the main voltage supply and an open position disconnected from the main voltage supply;

a power supply unit; and

a control device (1) configured to, when the on switch is initially moved to the closed position, generate an activation signal for actuating the switching unit to thereby move the switching unit to the closed position to activate the household appliance; and (2) configured to generate a deactivation signal to disconnect the switching unit from the main voltage supply when a treatment cycle is completed and to thereby deactivate at least the display unit;

wherein:

the control device is configured to initiate the activation signal if the power supply unit is in an OFF position when the actuatable switching unit is moved to the closed position and the control device is configured to initiate the deactivation signal if the power supply unit is in an ON position when the actuatable switching unit is moved to a closed position.

2. The household appliance of claim 1 , constructed in the form of a household dishwasher.

3. The household appliance of claim 1 , wherein the switching unit has at least one self-holding contact circuit, which is connected for signal transmission at least to the on switch and the control device.

4. The household appliance of claim 3 , wherein the self-holding contact circuit is connected to the on switch in such a manner that the self-holding contact circuit is switchable to a self-holding state.

5. The household appliance of claim 3 , further comprising a controller actuatable by the control device and operably connected to the self-holding circuit.

6. The household appliance of claim 3 , wherein the self-holding circuit has at least one relay or flipflop.

7. The household appliance of claim 6 , wherein the flipflop is an RS flipflop.

8. The household appliance of claim 1 , wherein the on switch is configured as a microswitch.

9. The household appliance of claim 1 , wherein the on switch is configured for operation by an operator.

10. The household appliance of claim 1 , wherein the control device is configured to deactivate the household appliance.

11. The household appliance of claim 1 , wherein the on switch is constructed to generate the deactivation signal by double switching actuation of the on switch.

12. The household appliance of claim 1 , further comprising an off switch configured to deactivate at least the display unit, wherein the on switch and the off switch are connected in a parallel manner.

13. The household appliance of claim 12 , wherein the switching unit has at least one self-holding contact circuit, which is connected for signal transmission at least to the on switch and the control device, said self-holding circuit being connected to the off switch in such a manner that the off switch is switchable to an open state.

14. The household appliance of claim 12 , wherein an equally high electrical voltage is present at the on switch and the off switch.

15. The household appliance of claim 12 , wherein the power supply unit is configured to form a series circuit with the on switch and the off switch.

16. The household appliance of claim 15 , wherein the power supply unit supplies the control device with electrical energy.

17. The household appliance of claim 15 , wherein the power supply unit supplies the operating display unit with electrical energy.
