  • the permanently visible indicator marking may comprise any pictographs that usually are employed in dishwashers, such as for example a schematic representation of a sun to indicate the necessity to refill rinse aid, or a schematic illustration of a spray yet to indicate that presently a rinsing operation is carried out.
  • the segmented numerical display can be any kind of segmented display in which the individual display segments can be individually turned on and off, so as to provide by combination of two or more of the display segments a representation of numerals or alphabetic characters.
  • the segmented display can be a seven-segment display or a nine-segment display.
  • the segmented numerical display preferably is a fourteen-segment display or a sixteen-segment display which are particularly suited for displaying not only the Arabic numerals but also the letters of the modern Latin alphabet.
  • the display element comprises a plurality of permanently visible indicator markings which are aligned to individual display segments.
  • the segmented numerical display is, for example, a seven-segment display
  • permanently visible indicator markings can be provided beside the seven-segment display so as to be aligned with the horizontal display segments.
  • the size of the indicator markings thus either three indicator markings could be provided on either side of the seven-segment display or, alternatively, two larger markings could be provided which are aligned to the uppermost and the lowermost, respectively, of the horizontal display segments.
  • permanent markings could be provided below or above the segmented display so as to be associated with any one of the horizontal display segments.
  • markings also could be provided in proximity to the corners of the segmented numerical display, wherein the markings thus could be pointed to either by the diagonal display segments or by illuminating several display segments in the shape of an arrow which points to the permanently visible indicator marking.
  • the display element shall be adapted to display multi-digit numerals
  • the display element can comprise a corresponding plurality of segmented numerical displays.
  • the segmented numerical display preferably comprises a liquid crystal display, a vacuum fluorescent display or an array of light-emitting diodes, in which manner numerical displays can be implemented which can be readily implemented at low costs and in virtually any size.
  • the present invention provides an appliance comprising a display element as it was referred to above, which appliance further comprises a control unit for selectively and individually operating the display segments.
  • control unit thus preferably is adapted to selectively operate the display segments in combination so as to indicate numerical or alphanumerical symbols, such as the Arabic numerals or the letters of the Latin alphabet, wherein the control unit further can selectively operate the display segments individually, or again in combination, such as in the shape of an arrow, so as to point to one or more of the permanently visible indicator markings.
  • the appliance can be a household appliance, and particularly can be a washing machine or a dishwasher.
  • Such appliances often comprise on the one hand a numerical display so as to indicate to the user the duration of a washing cycle carried out in the appliance and on the other hand a plurality of pictographical indicators which are related to certain parameters of the washing cycle, such as the type of the washing cycle, the instantaneous stage of the washing program, or which provide for a warning message such as in a dishwasher the need to refill regenerator salt or rinse aid.
  • the segmented numerical display has the double function of providing for a numerical or alphanumerical display and additionally is employed as a pointer to a permanently visible indicator marking
  • the present invention thus can be used to advantage is such appliances to provide for displays that require less space than known displays but still are able to convey the same or even a larger information content as known devices.
  • a display element 10 which is designed for use in a dishwasher and which in the embodiment shown in Fig. 1 comprises a nine-segment numerical display in which the individual display segments can be turned on and off individually so as to indicate any of the Arabic numerals from "0" to "9".
  • Display 10 further comprises three permanently visible indicator markings 14, 16 and 18 which refer to certain operational states of the dishwasher. While the segmented numerical display 12 can be employed for example to indicate a program number, such as the digit "1" which as shown in Fig.
  • the segmented numerical display 12 further can be employed to point to any of the permanent markings 14, 16 and 18 by illuminating associated display segments.
  • any display segments which before were used to indicate a number are turned off and instead the upper horizontal display segment 20 which is aligned to indicate a marking 14 is illuminated.
  • the segmented numerical display 12 shall be used to indicate that a rinse stage is in progress, the central horizontal display segment 22 which is aligned to indicate the marking 16 is turned on while all the vertical and diagonal display segments are switched off.
  • numerical display 12 is to be operated to point to indicator marking 18 which indicates that regenerating salt should be refilled, lower horizontal display segment 24 is illuminated.
