Definitions

  • the invention relates to a rotary toggle for operating a kitchen appliance, which can be inserted into a kitchen appliance front and/or kitchen furniture panel, with a knob and a base, the knob being mounted such that it can rotate relative to the base.
  • Such a rotary toggle is out DE 10 2005 032 509 B4 famous.
  • This rotary toggle has a fastening part made of plastic, which is designed as a light guide that transmits light from a light source from inside the household appliance to a display part on the outside of the household appliance.
  • the attachment part also contains attachment means for attaching the light source.
  • a disadvantage of the solution described is the complicated structure and also the non-uniform illumination of the display part by the light source.
  • a circuit board in the base which has at least one light-emitting diode
  • a light guide being arranged on the circuit board in the base, which directs the light from the light-emitting diode to a luminous ring of the base surrounding the knob directs, a simpler and cheaper construction of the rotary knob as well as a quick installation and a more even illumination can be made possible.
  • the circuit board in the base enables simple prefabrication by automatically arranging the light-emitting diode on the circuit board. This means that only the prefabricated circuit board has to be inserted into the base and the light guide arranged on the circuit board when assembling the rotary knob.
  • the light guide also directs the light to a ring of light surrounding the knob, so that the knob is evenly illuminated. This simplifies the handling of the rotary toggle even when the ambient light is weak and also enables a simple yet visually appealing configuration of the rotary toggle.
  • the circuit board has a plurality of light-emitting diodes in the base, with the light guide having a plurality of luminous channels which guide the light of the luminous diodes into the luminous ring.
  • the plurality of light-emitting diodes are preferably distributed uniformly on the circular arc of the light ring.
  • the light from the plurality of light-emitting diodes is preferably conducted into the luminous ring via a plurality of luminous channels of the light guide, so that a uniform distribution on the circular arc of the luminous ring can be achieved.
  • An embodiment is particularly preferred which provides that the light channels guide the light of the light emitting diodes along an axis of rotation of the knob and deflect it tangentially into the light ring surrounding the axis of rotation. With the deflection of the light from the emission direction of the light-emitting diodes along an axis of rotation of the knob towards a tangential introduction of the Light in the luminous ring surrounding the axis of rotation, a particularly uniform illumination of the luminous ring can be achieved by the light-emitting diodes arranged on the circuit board.
  • a particularly advantageous embodiment of the invention relates to the fact that the light channels distribute the light uniformly on the circular arc of the light ring into the light ring.
  • a particularly uniform illumination of the luminous ring and thus the knob is achieved by the evenly distributed introduction of the light from the luminous channels into the circular arc of the luminous ring.
  • each light-emitting diode is assigned a single light channel, which deflects the light emitted by the assigned light-emitting diode individually into the light ring and the light from the light-emitting diodes combined in this way illuminates the entire light ring completely surrounding the knob.
  • the light emitted by the plurality of light-emitting diodes is therefore brought together in the light-emitting ring via the light-emitting channels each assigned to a light-emitting diode.
  • the loss of light due to reflections and refractions is low due to the individual deflection of the light from each light-emitting diode, so that a high light intensity can be achieved in the light ring illuminated jointly by the light-emitting diodes.
  • the assignment of a single light channel to a single light-emitting diode ensures that the light ring is illuminated with as little loss as possible, since the light from the light-emitting diode assigned to the light channel can be deflected with low losses due to reflections and refractions via the individual deflection in the respective light channel. In this way, a particularly uniform illumination of the luminous ring that completely surrounds the knob can be achieved.
  • a particularly advantageous embodiment of the invention provides at least one detent mechanism, which is designed to haptically detent the knob in several ways when the knob rotates relative to the base to effect detents.
  • the user receives feedback via the tactile clicks of the knob when operating the kitchen appliance using the rotary knob, which makes handling the rotary knob easier.
  • the locking mechanism When the knob rotates in relation to the base, the locking mechanism generates haptic feedback as the knob engages in different locking positions.
  • the circuit board has a counter which is designed to count the haptic detents of the detent mechanism, the circuit board comprising a computing unit which is designed to convert the detents of the detent mechanism counted by the counter into operating signals for operation of the kitchen appliance.
  • the circuit board has a counter which is designed to count the haptic detents of the detent mechanism, the circuit board comprising a computing unit which is designed to convert the detents of the detent mechanism counted by the counter into operating signals for operation of the kitchen appliance.
  • knob is glued to a movable part of the locking mechanism, while another part of the locking mechanism is screwed immovably to the base, is particularly advantageous.
  • the knob By gluing the knob to the movable part of the locking mechanism, the knob can be easily attached. Since the other part of the latching mechanism is screwed immovably into the base, the latching mechanism serves to support and guide the knob relative to the base. The locking mechanism of the rotary toggle thus ensures the rotatable connection and storage between the base and the knob.
  • An advantageous embodiment provides that the screws for screwing the latching mechanism to the base protrude through the circuit board and fix it between the latching mechanism and the base. Both the locking mechanism and the circuit board can be fixed very easily in the base using these screws. A very simple and quick assembly of the rotary knob in production is thus possible.
  • the locking mechanism allows not only rotary movements of the knob about a rotary axis of the knob but also axial pressure movements of the knob in the direction of the rotary axis.
  • the user's axial pressure movements on the knob can result in opposite springback when the knob is relieved.
  • the knob can thus be displaced along the axis of rotation by axial pressure movements and then advantageously assumes an initial axial position again.
  • the circuit board has a sensor which is designed to detect the axial pressure movements, wherein the circuit board comprises a computing unit that is designed to convert the pressure movements detected by the sensor into operating signals for operating the implement kitchen appliances.
  • the luminous ring is surrounded radially by an opaque decorative ring, as a result of which the light is emitted through the luminous ring axially to the axis of rotation of the knob.
  • the emission of light through the luminous ring can very easily be guided axially to the axis of rotation of the knob via the decorative ring, so that the emitted light is guided along a gripping surface on a cylinder jacket of the knob.
  • the grip surface can be illuminated particularly evenly, so that the knob is easy to see and operate even in poor ambient light.
  • An advantageous embodiment of the invention provides that the decorative ring is attached to the base in a manually detachable manner via at least one bayonet catch.
  • the decorative ring can also be simply pushed over the toggle after the rotary toggle has been inserted into a kitchen appliance front and/or kitchen furniture panel.
  • the decorative ring is then attached using the bayonet catch fixed to the base. In the event of damage, the decorative ring can be easily assembled and disassembled by hand for replacement or cleaning.
  • An embodiment is particularly advantageous which provides that the base can be fixed in an opening of a device front and/or furniture panel by means of a base retaining ring that can be screwed to the base.
  • the base retaining ring can be easily mounted with the base in an opening in a device front and/or furniture panel. To do this, the base retaining ring is simply screwed onto the base after pushing the base through the opening on the opposite side of the device front and/or furniture panel.
  • the rotary knob 1 is used to operate a kitchen appliance that can be used in a kitchen appliance front and/or kitchen furniture panel. It has a knob 2 with a preferably corrugated gripping surface 17 and a base 3 , the knob 2 being rotatably mounted relative to the base 3 .
  • the rotary knob 1 can be fixed in an opening of a device front and/or furniture panel via a base retaining ring 16 that can be screwed to the base 3 .
  • this base retaining ring 16 is simply screwed onto an external thread 18 of the base 3 onto the base 3 after the base 3 has been inserted at the external thread 18 through an opening in a device front and/or furniture panel.
  • the rotary knob 1 has an illuminated ring 7 surrounding the knob 2 , which illuminates the rotary knob 1 and in particular the knob 2 .
  • the light ring 7 is radially surrounded by an opaque decorative ring 15, whereby the emission of light through the light ring 7 is axial to the axis of rotation 9 ( 3 ) of knob 2.
  • the figure 2 shows the rotary toggle 1 according to FIG figure 1 in a side view.
  • the rotary toggle 1 can easily be fixed in an opening of a device front and/or furniture panel by screwing the base retaining ring 16 onto the external thread 18 of the base 3 .
  • the device front and / or furniture panel between the base retaining ring 16 and a projection 19 of the base 3 is clamped.
  • FIG 3 is a first, side sectional view through the rotary toggle 1 according to figure 2 shown.
  • a locking mechanism 10 can be seen, which is designed to cause haptic locking of the knob 2 in several locking positions when the knob 2 rotates relative to the base 3 .
  • the knob 2 is glued to a movable part 12 of the locking mechanism 10, while another part 13 of the locking mechanism 10 is screwed to the base 3 so that it cannot move.
  • the screws 14 for screwing the detent mechanism 10 to the base 3 preferably protrude through a flat circuit board 4. As a result, the circuit board 4 is easily fixed between the detent mechanism 10 and the base 3 via the screws 14.
  • the figure 4 shows a further, lateral sectional view through the rotary toggle 1, the sectional plane being opposite to the sectional view in figure 3 is twisted about the axis of rotation 9 .
  • the circuit board 4 has light-emitting diodes 5 in the base 3 .
