  • a panel is shown in FIG1 .
  • the panel 1 is provided with a first control element 2, which is a knob 12' that can be turned for selecting either a functionality, for example the selective activation of one or more heating elements or a fan, or a temperature.
  • the panel 1 is further provided with a second control element 4, which is a further knob 14' that can be turned, for selecting the other of functionality or temperature.
  • the knob 12' and the further knob 14' might be either designed as knobs protruding permanently from the panel or as push-in push out buttons which protrude only in use of the oven.
  • control unit for an electromechanical oven comprises:
  • the control element are now arranged concentrically, while the first and second converter are arranged separately from each other.
  • the first and the second converter are electromechanical components which convert a rotating movement or predetermined rotational position of the respective control element into an electrical signal.
  • the splitting unit comprises a gear set, wherein in particular the gear set is arranged in a box.
  • the splitting unit is provided as bearing for one or more gears of the gear set.
  • the knob is connected by a first axis to the first converter.
  • the knob and the first converter are arranged in an on axis configuration.
  • the ring selector is connected over the gear set to a second axis to the second converter.
  • the second axis is different from the first axis.
  • the first and the second axis are parallel to each other and the first and the second axis are spaced apart from each other.
  • the gear set comprises at least a first gear and a second gear, wherein the second gear is arranged on the second axis and/or the first gear is arranged on the first axis.
  • the gear set comprises a third gear interconnecting the first gear and the second gear.
  • the splitting unit comprises a box, in particular a box with a cover.
  • the third gear being integrally formed with an axle and/or the box forming bearing for the third gear.
  • the box or cover might from a bearing by providing a ring shaped protrusion.
  • the first and the second converter are placed side by side, in particular at the same distance from the splitting unit.
  • the distance is in particular a distance in the direction of the first axis.
  • the first gear is provided with a ring shape for concentrically attaching to the back side of the ring selector.
  • a design ring is placed between the knob and the ring selector.
  • the knob and the ring selector are provided with a push button mechanism.
  • the first control element selects a heating temperature and the second control element selects a heating function of the oven.
  • a heating function might be for example top heating, bottom heating, hot air or convection heating or a combination thereof.
  • an oven with a control unit comprising a casing, a muffle and one or more heating elements and/or cooking functions, the oven being provided with a panel, wherein the first and second control element are arranged with this panel, in particular arranged in the center of the panel.
  • the control unit is provided according to one of the above embodiments.
  • FIG 2 shows an embodiment of the control unit 10 being connected to a panel 1.
  • the control unit is provided with or comprises a first control element 2 and a second control element 4.
  • first control element 2 is provided as central knob 12 and second control element 4 is provided as ring selector which is concentrically arranged around the knob 12.
  • second control element could as well be the knob and the first control element the ring selector.
  • the knob 12 as well as the ring selector 14 are designed to control a function or a temperature of an oven by turning the knob or the ring selector to a designated position and thus switching to a function or temperature by means of the converters being electromechanical components.
  • the knob 12 and the ring selector 14 might be provided each with a push-in push-out mechanism, such that the knob 12 and the ring selector 14 might be both in a protruding position, only the knob 12 is in a protruding position or non-of them is in a protruding position.
  • FIG 3 shows an exploded view of the control unit and the position of panel 1.
  • Knob 12 is located on a first axis A1 and is provided with a handling part 12a with axis pin 12b directed to a back side.
  • the ring selector 14 has a flat surface located in a handling part 14a of the ring selector 14 and a flange 14b protruding to an back side.
  • an optional design ring 13 In between the ring selector 14 and the knob 12, there is shown an optional design ring 13.
  • the design ring 13 is as well provided with a protruding flange 13b. This design ring 13 might be fixed with the knob 12 or with the ring selector 14.
  • the flanges 13b, 14b as well as the axis pin 12b are designated to pass through a hole in the panel 1.
  • the splitting unit 20 comprises a box 28 and a cover 29 for closing the box 20. Inside the box 28, a gear set is arranged.
  • the gear set comprises at least a first gear 22 and a second gear 24.
  • the first gear 22 is arranged on the axis A1 and the second gear 24 is arranged on the second axis A2.
  • the first and the second axis A1, A2 are arranged parallel to each other and spaced apart from each other.
  • the first gear 22 is provided as ring, such that an axis from the knob 12 extending to the first converter 30 and a matching axis 31 of the first converter extending to the knob 12 may pass, in particular centrally through the first gear 22 without contacting this first gear 22.
  • This axis from the knob 12 to the first converter 30 extends through opposing holes 40, 42 in the box 28 and the cover 29.
  • the first gear 22 is attached to the flange 14b of the ring selector 14 and is fixed regarding a circumferential direction.
  • the first gear 22 engages with the second gear 24 by means of a third gear 26.
  • the third gear 26 is arranged between the first gear 22 and the second gear 24.
  • the second gear 24 is connected to the second converter 32 by means of an axis A2.
  • the axis from the second gear 24 to the second converter 32 passes through another hole 44 in the cover 29, wherein a part the box 28 opposing this hole might be provided as bearing 46.
  • the second converter 32 is provided with an axis pin 33.
  • the third bearing 26 engages with the first bearing 22 and the second bearing 24 as shown as well in FIG 4 .
  • the third bearing 26 is arranges between the first bearing 22 and the second bearing 24.
  • the third bearing 26 may be provided with an integral axle 27, wherein the cover 29 or alternatively the box 28 serves as bearing 48 for the axle 27 of the of the third bearing 26.
  • FIG 5 shows the panel 1 with the control unit 10 from the back side.
  • the first converter 30 and the second converter 32 are arranged side by side. Those converters are arranged at a back side of the splitting unit 20 comprising the box 28 and the cover 29.
