Definitions

  • the invention relates to a rotary adjusting device, according to the preamble of claim 1, in particular a household appliance.
  • Known adjusting devices of this type are usually unlighted. In poor ambient light conditions, therefore, the setting state is often a bit difficult to recognize, which also takes time. In kitchens, for example, the light is mostly concentrated on the worktop and the user's eye is set to this brightness.
  • the built-in furniture front in which the control panels of household appliances such as stoves or ovens are arranged, is usually much less illuminated, especially under the edge of a kitchen countertop.
  • the document WO03 / 058659 A1 discloses a combination of a rotary actuator and a display panel according to the preamble of claim 1.
  • the publication EP 0 590 170 A1 describes an operating device which serves to operate functional units of a motor vehicle. It includes a control knob which is rotatably mounted on a lid. In an insertion of the control knob, a light guide is inserted. The light guide is used to display the respective instantaneous rotational position of the control knob. For this purpose, the light guide is inserted into the insertion opening from the visible side or front side of the control knob, so that a free end of the light guide is flush with the end face of the control knob. The light guide thus forms a position marker, which indicates the respective current rotational position of the control knob. For this purpose, a light source is provided, which in a closed by the lid housing is arranged. The light guide also symbol surfaces - such as sword wedges or step numbers - assigned - which are mounted on the lid.
  • a control device for motor vehicles which has a housing, an actuating shaft, an actuating button, as well as a light source.
  • function symbols mounted outside the actuating button can be illuminated, namely by a light emission window.
  • the light exit window is arranged eccentrically on the actuating button or the actuating axis, whereby the position of the light emission window changes when turning the actuating knob. The light can therefore be thrown in each switching position by one and the same window on the respective switching position corresponding function symbol.
  • the light exit window is located on a rear side of the actuating button.
  • Indicator is relative to the actuator, indicate the setting.
  • the beam serves as a large index mark.
  • the beam contains visible light and illuminates the highlighted surface area, which may be at least partially reflective.
  • characters or symbols characterizing the respective operating state are displayed on the surface areas, e.g. Numerals are printed, these characters being able to form the highlightable surface areas by e.g. printed with a color that is excited to emit light when irradiated with an otherwise invisible UV light.
  • the signs are applied with a reflective color which reflects a beam of visible light and thereby accentuates the character from the surface area highlighted by the illumination. The user can easily read a brightly highlighted character.
  • Various hybrid forms are possible with beams that combine different wavelengths and different surface designs.
  • the surface area to be emphasized may simply be a reflective or light-emitting surface area in which a character, e.g. a symbol or a figure is left out and can be seen on closer inspection.
  • a character e.g. a symbol or a figure is left out and can be seen on closer inspection.
  • the limited beam i. the more or less collimated, directed beam or billet emerges inclined onto the display surface from the control element and irradiates a limited spot or area on the display surface. It can also emerge more or less parallel to the display surface to the side of the actuator and the display surface, wherein a beam of visible light, a long light finger is achieved, which can facilitate the reading as a kind of large index mark.
  • the beam can also be bundled very narrow in the shape of a pointer and form a relatively small marking spot or narrow light pointer on the display surface, which can also lie across a symbol or as a marker next to a symbol.
  • the lighting device has a switch, by means of which it is set or switched off when activating or deactivating the device or the actuating element.
  • the radiation source is a light emitting diode, and arranged together with an accessible for the user to exchange electrical energy storage, for example, a button cell in the control element. The radiation source and the energy storage can be combined to form a compact, exchangeable unit.
  • Such a turntable can also be used in devices without electronics or non-electrical devices, such as gas appliances.
  • the control element In order to obstruct the view of the display surface as little as possible from lateral directions, the control element is tapered towards the front side.
  • the actuator has a handle bar or a toggle handle, which is preferably kept narrow in axial view.
  • the control element in addition to the lateral light exit point which already functions as an index mark, the control element has on its cover side an illuminated index mark, which is preferably also fed by the lighting device and can further facilitate orientation.
  • reading the operating state is the control element or at least a part thereof, for example, the front or front surface or its periphery dimly lit or lit, for which they as a light guide trained and can be powered by the lighting device.
  • the actuating element illuminates in the same color as the assigned, emphasizable surface areas and different actuating devices on a device preferably have different colors.
  • the Figures 1 and 2 show a section of a control panel 12 made of plastic, which forms part of the device housing of a household stove, not shown, with a rotary adjusting device 10 for adjusting the heating power of a cooking zone of a cooktop, not shown.
  • the control panel 12 has a flat, vertical front panel 14 with a circular opening 16 to the rear of a guide cylinder 18 connects.
  • This is a rotatable actuator in the form of a rotatable about a horizontal axis, flat, ie low over the control panel 12 projecting knob 20 with a cylindrical peripheral wall 22 rotatably guided and axially displaceable.
  • the known countersink mechanism is omitted for simplicity.
  • the rotary knob 20 shown in the extended position has the front side of a removable cover 24 inserted into the peripheral wall 22.
  • the extendable part of the peripheral wall 22 has an axially parallel extending slot-shaped aperture into which a light guide 26 is inserted in the form of an axially and radially extending flat disc which closes the gap and is flush with the outside of the peripheral wall 22.
  • the lid 24 also has a radially outwardly extending radial slot into which the light guide 26 engages to form an illuminated front index mark 28 from the edge.
  • the cover 24 carries on its back a voltage applied to the light guide 26 light emitting diode 30, a switch 32 and an electric battery in the form of a button cell 34, which together with the light guide 26 form a lighting device.
  • the button cell 34 is removable after removal of the lid 24 by the user.
  • the switch 32 cooperates in the retracted state of the knob 20 with a support, not shown, in the device housing to turn off the lighting device.
  • the light-emitting diode 30 emits a visible light which emerges from the rotary knob 20 via the light guide 26 as a slightly broadening light beam 38 in the radial direction and has an on the display surface in Fig.1 Illuminated by broken lines 40 indicated surface area or sector with a light finger approximately parallel to the surface. From this, the respectively irradiated digit 36 of the surrounding imprinting stands out in a reflective manner. Also, the index mark 28 formed by the light guide 26 is illuminated.
  • FIGS. 3 and 4 show a section of a control panel 312 made of plastic, which forms part of the device housing of a household stove, not shown, with a rotary adjusting device 310 for adjusting the heating power of a cooking zone Cooktop.
  • the control panel 312 has a planar vertical front panel 314 with an opening 316 through which a horizontal switch shaft 318 extends. Then an actuator in the form of a rotatable about a horizontal axis, low rotary knob 320 is attached.
  • the power supply of the light emitting diode 330 is carried by the interior of the electrical appliance via a slip ring connection and a switch, which are not shown here.
  • the end wall 346 has one, approximately in a plane defined by the axis extending slot-shaped opening into which a light guide 326 is inserted, which closes the slot and terminates flush with the outside of the end wall 346.
  • the top wall 324 has a radial slot extending peripherally from the edge toward the center into which the light guide 326 engages to form an illuminated front index mark 328.
  • a the entire front surface of the knob 320 overlapping, translucent optical fiber disk 341 is placed, which is also brought from the light guide 326 via the, visible through them index mark 328, brought to a faint glow.
  • the dim glowing optical fiber disk 341 has the purpose of allowing the user to more quickly identify the highlighted surface area of the display surface to the rotary knob 320 in poor room lighting conditions, increasing the safety and speed of reading the operating condition and thus ease of use.
  • the control panel 312 near part of the light guide 328 is formed as a lens 350, which is illuminated by the light-emitting diode 330 with visible light and the light, for the most part as a collimated light beam 338 obliquely backwards, where he on the surface forming a display surface the control panel 312 an oval, in fig3 irradiated in a dashed line light spot 340, in which a symbol in the form of a numeral 336 is printed with a reflective color.
