Water-conducting household appliance with a storage container and a metering pump

摘要

A water-conducting domestic appliance 1, which serves in particular as a laundry treatment appliance for washing and / or drying laundry, comprises a storage container 15, which serves to receive at least one liquid treatment agent, a driven by an electric motor 18 metering pump 19 and a controller 23, for driving the Electric motor 18 of the metering pump 19 is used. In this case, the controller 23 controls the electric motor 18 of the metering pump 19 in a normal mode so that the metering pump 19 conveys the liquid treatment agent from the reservoir 15 into a treatment area 9. In a cleaning mode, the controller 23 controls the electric motor 18 of the metering pump 19 at least temporarily so that the electric motor 18 generates an increased torque and / or a varying torque for driving the metering pump 19. Here, the controller 23 may drive the electric motor 18 in the cleaning mode with a higher and / or pulsed voltage. This makes it possible to clean the metering pump 19 and further elements of a metering device 16 of the domestic appliance 1. Thus, the operability and the possibility of cleaning the metering device 16 for a user is facilitated.
