1. An apparatus, comprising:

  • a household appliance for treating objects, the appliance including;

    a control facility and an operating facility, said operating facility being a touchscreen;

    said control facility being configured to display on said touchscreen first and second tenable control variables of the household appliance in a form of demarcated, flat, touch-sensitive operating elements on said touchscreen on at least two screen displays B1, B2 of different hierarchy;

    said first settable control variables being treatment programs for the objects to be treated and second settable control variables being program parameters with changeable parameter values assigned to the treatment programs;

    wherein first operating elements assigned to treatment programs which are selected by touching an assigned first operating element are displayed on a hierarchically higher screen display B1 with a hierarchy H1 and second operating elements that allow a setting of said program parameters are displayed on at least one hierarchically lower screen display B2 with a hierarchy H2<

    H1;

    wherein said hierarchically higher screen display B1 is followed by the hierarchically lower screen display B2 when a first operating element is selected by touching and at least a part of said second operating elements has elongated sensor elements, in a longitudinal direction of which an assigned parameter value changes so that the parameter value can be set by touching the elongated sensor element;

    said control facility being configured so that touching a first said operating element on screen display B1 results in a screen display B3;

    on which at least some of the program parameters and their parameter values are displayed on third operating elements, wherein the screen display B2 results when a third operating element assigned to a changeable parameter value on screen display B3 is touched;

    said control facility being configured to enable a direct start of a treatment program on said screen display B1, when a sub-region of a first operating element provided for the purpose is touched;

    said control facility configured to use acoustic signals to indicate at least one item selected from the group consisting of a performance of a treatment program and a transition between two program stages wherein the acoustic signals indicating the performance of the treatment program are output during the performance of the treatment program; and

    said control facility configured such that a frequency or intensity of the acoustic signals is a function of a type of program stage being performed or a transition between two program stages, wherein said control facility has stored therein a relationship between the frequency or intensity of the acoustic signals and the type of program stage being performed or a transition between two program stages.
