Definitions

  • Optical switching stage display for rotary selector switches for household appliances, especially for stoves.
  • the invention relates to an optical switching stage display for household appliances equipped with rotary selection switches according to the preamble of claim 1 and is based on GB-A-584 163.
  • a rotary selector switch with an optical switching stage display is known.
  • a light-guiding element is arranged within the rotary knob of the rotary selector switch, which ends as a luminous point on the face of the knob.
  • the lighting device with a light change element is arranged on the stationary part of the rotary selector switch.
  • the light guide element is illuminated with different light intensities.
  • a relatively small illuminated dot indicates the different switching stage settings and the different light intensity is poorly recognizable depending on the level of the switching stage setting.
  • an optical display device of the aforementioned type in which a reflector screen is resiliently mounted on the switch axis of the rotary selector switch.
  • this reflector cover is lifted from an overrun cam and brought into an inclined position, so that the light rays emanating from the illumination source can reach the display surface visible in the front of the switch cover from the inclined reflector cover. In the off position, on the other hand, the reflector cover hides this display area.
  • the disadvantage of the above-described embodiment is that the accommodation of the reflector on the switching axis of the rotary selector switch is very complex and that the users can not see the switching level display particularly well due to the relatively small field of view of the display area.
  • a node control acknowledgment switch is known from DE-A-17 90 124, in which a respective operating state is identified by different colors. To do this, a multi-colored roller is rotated over an internal opposition lamp by means of an operating button.
  • Such a structure is, however, for arrangement in a household appliance equipped with rotary selection switches, e.g. not suitable for a stove, since switching level settings should be displayed here using different light intensities.
  • the invention has for its object to provide an optical switching stage display for household appliances, in particular stoves, in which the set switching stage is easy and clear for the operator and in which this can be achieved by relatively simple construction measures in the switch area.
  • the advantage of the embodiment according to the invention lies in the fact that the user not only sees the individual identification symbols or switching stage markings, but that he can also assess the current switching stage setting from a great distance by means of the intensity of the light or color signals. In addition, this effect is realized by means of simple and compact devices in the area of the rotary selector switches.
  • Rotary selection switches 2 are arranged in the switch panel 1 in the usual manner for setting the hotplates or the baking oven (not shown).
  • a circular, transparent display field 3 is formed in the area around the rotary selector switch 2.
  • a fixed reflection shell 5 is attached behind the switch panel 1 within a switch box 4.
  • a light receiving space 6 for accommodating an electrical light 7 is formed in the upper area of this reflection shell 5.
  • a pot-shaped unit 8 is arranged within the reflection shell 5 and is coupled to the rotary selector switch 2.
  • the cup-shaped unit 8 consists essentially of the display disc 9 and the cylindrical light change or light attenuation element 10.
  • the cup-shaped unit 8 is made of a translucent material.
  • a likewise transparent color film layer 11 is printed or glued on the cylindrical outer surface of this cup-shaped unit 8.
  • the color film layer 11 rises on the circumference of the light changing element 10, i.e. an area with a low color film coverage of the light changing element 10 is continuously increased up to an area with a large color film coverage of the light changing element 10.
  • the above-described embodiment now has the effect that when the rotary selector switch 2 is rotated, the lamp 7 is switched on and under the lamp 7, the first one Area with the small color film width.
  • the display panel 3 shows only slightly light-red illumination of the display disc 9.
  • the rotary selector switch 2 is now set to higher switching levels, a larger color film area also passes under the lamp 7 and that from the reflection bowl 5 to the front Display disc 9 reflected light now gets an increasingly intense and powerful red color drawing.
  • the user can also obtain information about the switching level currently set due to the different color intensity of the lighting.
  • the different lighting intensity in the display field 3 can be achieved by graduated material clouding of the light changing element 10.
  • an increasing translucent opening can be formed in the light changing element 10.
  • the reflection shell 5 itself can be lined with a silver or colored reflection layer and sprayed as a plastic part in a reflected material.
