Definitions

  • the invention relates to an operating device for a household appliance or the like. Furthermore, the invention relates to an arrangement comprising a plurality of the aforementioned operating devices. Moreover, the invention relates to a household appliance with one or more such operating devices.
  • Operating devices which are provided in particular for household appliances, usually have a display device by which the user is informed about the position or the state of a control element.
  • This display device indicates, for example, whether a device that is driven by the operating element, is in the on, off or in an intermediate adjustable state.
  • Conventional operating devices often have integrated lighting and a display device which is at least partially translucent.
  • the display device may have, for example, numbers, letters and / or symbols.
  • the display devices which are partially translucent, are usually first painted and then treated with a laser. As a result, those places that are to be translucent, freed from the paint. In another method, an opaque mask is sprayed on translucent material.
  • the operating devices with conventional display devices have the disadvantage that on the one hand the production of the imprint is a complex and expensive process and on the other hand, the imprint does not have sufficient abrasion resistance. In addition, often the imprint is transilluminated, which is undesirable.
  • the operating device comprises a base part, which is mounted or attachable in or on the household appliance or the like, and an operating element, which is movably mounted on the base part and has at least one light-transmissive area. Furthermore, the operating device comprises an inner part, which in places according to a predetermined scheme translucent and disposed within the operating element, and at least one light source, which is disposed within the base part or within the inner part.
  • the essence of the invention is that that part which is partially transparent, is not arranged on the outside, but within the operating element. This ensures on the one hand abrasion resistance, since it is not accessible to the user, and on the other hand allows a cost-effective production, since an imprint meets the requirements and thus the complex and costly Painting and laser treatment are not required.
  • the inner part is assigned to the transparent area of the operating element. This ensures that the light emanating from the light source can only escape through the transparent areas of the inner part and then through the light-transmitting area of the operating element to the outside. In this way, the externally visible pattern of light is determined by the configuration of the inner part.
  • the inner part is formed with the operating element at least partially positively. This enables a stable cohesion of the components. Other fasteners are not necessarily required.
  • the operating device comprises at least one reflector. This allows an increase in the light output and a targeted deflection of the light to a desired range.
  • the reflector is preferably arranged within the operating element. This causes an optimization of the light output.
  • the operating element, the inner part and / or the reflector may be formed substantially rotationally symmetrical. This contributes to ease of manufacture and easy assembly of these components.
  • the operating element is rotatably mounted on the base part.
  • the operating element is designed for example as a rotary knob.
  • Numerous electrical and mechanical control and regulating elements are adjustable by turning.
  • the control element according to the invention can be coupled with such control and regulation elements.
  • the inner part has an imprint.
  • On the inner part of the print is not exposed to abrasion.
  • colors with low adhesion can be used.
  • the colors can be selected in particular according to their opacity.
  • the imprint can be applied in a simple and cost-effective manner.
  • the imprint is a numerical scale. This is a convenient way to characterize the position or condition of the operating element.
  • the numbers are shown as translucent areas or areas. This will make the numbers bright and the spaces and surroundings dark.
  • the imprint may be a progress indicator.
  • the progress indicator is represented by a tapered strip, which surrounds the inner part in the circumferential direction at least partially. This is particularly suitable for clearly indicating to the user the current position and the desired or required direction of rotation.
  • the tapered strip is opaque.
  • the inner part is made of a light-scattering material. This causes a uniform light distribution.
  • the inside of the translucent area may have a textured surface. This also contributes to a more uniform light distribution and can compensate for any inaccuracies in the imprint.
  • the structure surface also prevents the transillumination of the imprint from being perceived.
  • the at least one light source may preferably be formed as a light-emitting diode (LED). This means a low design effort and low power consumption.
  • LED light-emitting diode
  • an operating order is provided which has a plurality of operating devices described above.
  • the invention relates to a household appliance which has at least one of the operating devices described above.
  • FIG. 1 shows a sectional view of a preferred embodiment of the operating device according to the invention.
  • the operating device comprises a base part 10 and an operating element 12.
  • the base part 10 is mounted or attachable in or on a device, for example a household appliance.
  • the operating element 12 is formed substantially rotationally symmetrical and rotatably mounted on the base part 10. Both the base part 10 and the operating element 12 have cavities in the interior.
  • the base part 10 there is a light source 14.
  • the base part 10 may also have a plurality of light sources 14.
  • the base part 10 comprises a shaft 22 which is rigidly connected to the operating element 12.
  • the shaft 22 may, for example, be connected to an electrical or mechanical control element which is adjustable by rotation.
  • the control element can be, for example, a potentiometer, a rotary capacitor or an adjustable valve.
  • the operating element 12 has a light-permeable region 16, which also forms the essential part of the lateral surface of the operating element 12.
  • the translucent area 16 is partially covered by a cap 24.
  • the operating element 12 comprises an inner part 18 which is arranged in a form-fitting manner within the lateral surface of the operating element 12. On its outer side, the inner part 18 has an imprint, which is visible through the translucent region 16 from the outside.
  • the light emitted from the light source 14 is reflected by the reflector 20 toward the inside of the inner member 18. Subsequently, the light penetrates the transparent areas of the inner part 18 and then the transparent area 16.
  • the inner surface of the translucent region 16 is structured so that the light distribution is even more uniform and inaccuracies in the print are laminated.
  • the light source 14 may be disposed within the inner member 18. It is also possible for a plurality of light sources to be arranged in the inner part 18. In this case, the reflector 20 is not essential.
  • FIG. FIG. 2 shows an inner part 18 of the illumination device according to FIG. 1 with a first exemplary imprint.
  • This first exemplary imprint is a numerical scale 26, ie a series of consecutive numbers.
  • the hatched area in FIG. Fig. 2 illustrates an opaque region 30 which forms a strip around the inner part 18 around forms, on which only the numbers form the translucent areas.
  • the inner part 18 has projections 32, which are formed complementary to recesses in the region 16. The projections 32 thus prevent twisting of the inner part 18 relative to the transparent area 16 of the operating element 12.
  • FIG. 3 shows the inner part 18 of the illumination device according to FIG. 1 with a second exemplary imprint.
  • the second print is a progress indicator 28 represented by a tapered strip.
  • the progress indicator 28 with the continuously tapered strip is particularly suitable for the symbolic representation of the position of the operating element 12 and thus a certain state.
  • the inner part 18 has projections 32 which prevent the inner part 18 from rotating relative to the light-permeable region 16 of the operating element 12.
  • the operating device according to the invention is not only suitable for household appliances, but also for electrical, electronic, mechanical, hydraulic, pneumatic and / or similar devices.
