Circuit arrangement for operating a domestic appliance, probe module for a domestic appliance and method for operating a domestic appliance

摘要

The invention relates to a circuit arrangement 1 for operating a domestic appliance, with a circuit input 3 for applying an AC supply voltage (UV), with a control device 2 for controlling an operating process of the domestic appliance according to a selected operating program, with a voltage supply unit 9 coupled to the control device 2 for providing a Operating DC voltage UB for the control device 2 from the supply AC voltage UV, and with a push button module 14 with a push button 15 which can be actuated by an operator. The push button 15 can be used to couple the voltage supply unit 9 to the circuit input 3. The circuit arrangement also comprises an electrical switch 8 connected in parallel with the button 15, which can be switched by the control device 2 between an electrically conductive switching state, in which the voltage supply unit 9 is coupled to the circuit input 3, and an electrically blocking switching state, the control device 2 for this purpose is designed to switch the electrical switch 8 into the electrically conductive switching state after the operating voltage UB has been provided by the voltage supply unit 9 after the operator has actuated the button 15. A program selector 26, which can be actuated by the operator, for selecting the operating program of the domestic appliance is integrated into the push button module 14. The invention also relates to a push button module 14 and a method for operating a domestic appliance.
