METHOD FOR ENGAGING A SAFE OPERATING STATE OF A DEVICE OF A HOUSEHOLD APPLIANCE, CIRCUIT CONFIGURATION FOR OPERATING A HOUSEHOLD APPLIANCE, AND HOUSEHOLD APPLIANCE

摘要

The invention relates to engaging a safe operating state by a device (5), in particular a door locking device (5), of a household appliance, without great complexity with respect to software. According to the method, a main control unit (7) of the household appliance receives an input signal (51) and transitions the door locking device (5) from a first operating state into a second operating state due to the input signal (51). A motor control unit (13) for controlling an electric motor (12) of the household appliance is supplied with electrical power. The main control unit (7) transmits a first control command to the motor control unit (13), causing the motor control unit (13) to start operating the electric motor (12). After a first predetermined criterion is fulfilled, the motor control unit (13) actuates a lockout circuit (36), wherein, as a function of actuation, the lockout circuit (36) prevents the main control unit (7) from transferring the door locking device (5) from the second operating state into the first operating state.
