  • the present invention relates to a user control panel for laundry treatment appliance, which is designed for selecting one or more treatment operating phases of a selected laundry treatment program such that, in usage, only a specific part of the selected laundry treatment program may be performed.
  • laundry treatment appliances such as laundry washing machines, i.e. laundry washing machines which wash and rinse laundry, or laundry washing and drying machines, i.e. laundry washing machines which can also dry laundry, or laundry drying machines, i.e. laundry machines which dries the laundry
  • laundry treatment appliance can be referred indiscriminately to a laundry washing machine, or to a laundry washing and drying machines, or to a laundry drying machine.
  • laundry treatment machines are typically provided with a control panel to enable the operator to select a desired main laundry treatment program to be performed.
  • the control panel generally comprises a graphic interface, structured to show/provide a number of different selectable main laundry treatment programs that laundry treatment machine is able to perform, and one or more input devices, i.e. rotary switches and/or buttons, to enable the operator to select a desired main laundry treatment program among the performable main laundry treatment programs.
  • the number of selectable prefixed main laundry treatment programs is very high (for example there could be twenty-five selectable main laundry treatment programs, even if many of these main laundry treatment programs are actually only parts of other main laundry treatment programs), and causes, on the one hand, the graphic layout of the user control panel to be very complex, and, on the other hand, the operator to be confused about the right main laundry treatment program to be selected, so that the probability of selection of a wrong main laundry treatment program may be high. Therefore it happens often that operators remain frustrated in searching the right main laundry treatment program to be used when the number of selectable programs illustrated in the control panel is so high. Operator typically wishes to have a very intuitive control panel in order to be able to quickly select the right main laundry treatment program without effort and errors.
  • laundry treating appliance manufactures would like to have an economic control panels which, on the one hand, are simple and intuitive to be used by the operator and, on the other hand, may be easily mounted in several different models of laundry treatment machines, irrespective of the number of main laundry treatment programs.
