Definitions

  • the invention relates to a control panel such as the type, as it is the system “ DIEHL TC 2" or as the system “ GO Touch Control G II " on the market.
  • a control panel such as the type, as it is the system “ DIEHL TC 2" or as the system “ GO Touch Control G II " on the market.
  • Such panels consist essentially of a arranged in front of the cooking zones in the hearth or next to the cooking zones in the field and the worktop of a cooker, non-piercing and opaque inked insulating plate, under the contactless switch in the form of proximity or capacitance sensors and optoelectronic indicator lamps in Form of punctiform or arranged by seven-segment light-emitting diodes.
  • each cooking zone in the control panel is a switching point with her closely adjacent display geometrically assigned.
  • control panels of this type usually have a sandwich construction of two mutually distanced parallel circuit boards with appropriate mutual connection costs and installation depth requirements, which requires high manufacturing and testing costs.
  • a hob with several cooking zones is known, each of which is assigned a button for the cooking level preset, which in a keypad distributed in accordance with the mutual arrangement of the cooking zones. If one of the cooking zones is selected via its button, its heating capacity can be selected set via a plus / minus button pair and one between the Keypad and the sensor keys located 7-segment display. Regardless of this control panel for the cooking zones has the local Cooker over a timer in terms of cooking time or cooking time each of the cooking zones, which are addressed cyclically via a function key can.
  • the timer can be changed via a plus / minus button pair be, with the simultaneous operation of both buttons switching between Hour and minute defaults as well as switching between time duration and dial time.
  • a Pair of 7-segment displays either assigned to a cooking zone or else only once available. In the latter case, a signal field is additionally required, in which lights are assigned to the individual cooking zones and for those Cooking zones permanently light up, where already made timely while the indicator for that cooking zone is flashing, just one Timing is possible. Aspects of optimizing the circuitry for a individual cooking levels - default are not covered in this publication.
  • each cooking zone is a cooktop Plus / minus switch pair assigned for the cooking level setting.
  • One with one Symbol mask covered light source is on a circuit board under the glass ceramic cooking surface arranged next to the respective switch. The symbol exists in particular from the letter "H" to a risk of injury Remind the residual heat when the cooking zone is switched off.
  • Residual heat indicator is set forth in DE 1 99 25 228 A1, that they directly sensory or indirect by a count corresponding to the cooling process can be presented. Should the residual heat indicator due to a power failure disappear, then this is particularly signaled to point out that at least one of the cooking zones can still be hot.
  • a control panel 14 In addition to a Elektroherdmulde 11 with four cooking zones in the example shown 12, e.g. equipped with radiant heaters, or in their stovetop 13 integrated there is a control panel 14, with respect to the arrangement his switching points 15 and 16 display points in the drawing right once zoomed in detail is shown.
  • the surface of the control panel 14 is for the function of the switching and display points 15, 16 are not broken, whose Sensors and lamps are thus under the operator and visible surface the control panel 14 and optionally back in the translucent Plate sunk or simply pressed against it.
  • the switching points 15 in Control panel 14 are therefore the reactive areas of proximity or touch switches for example on the basis of retro-reflective sensors with invisible radiation or based on capacitive sensors.
  • switching points 15 act as Pulse inputs to bistable switches, usually in a processor are realized, the parent control tasks about as a according to program sequence, what in the drawing to ensure the overview but not received in circuit.
  • the control panel 14 mainly contains a power switch 17, a Cooking zone selection switch 18 and a cooking level switch 19, which in two opposite Features 19- and 19+ for lifting or lowering the heating power is divided.
  • a safety switch 20 with electro-optical Lock indicator 21 like the other indicator lights in the form of a Light bulb or a light-emitting diode, appropriate.
  • the Selector switch 18 is associated with such display points 16, in which it is preferably around the cooking zones 12 geometrically associated cooking zone lamps 22nd acts, and at least as an example, outlines a single digital one Cooking level indicator 23 in the form of a seven-segment ziffemdarwolf, which then is arranged in the center between the lamps 22.
  • the components of the switching points 15 and the display points 16 are on one single double-sided laminated board arranged (not in the drawing visible) distanced to the control panel 14 extends below this and its circumference not, at least not significantly, towering over.
  • This board is for the assembly prepared with the cooking level indicator 23 so that the single-digit alphanumeric Characteristic display compared to the representation in the drawing, too can be positioned rotated by 90 °, whereby the control panel 14 instead of the illustrated vertical arrangement a horizontal orientation in or beside the Herdmulde 11 can learn.
  • the hob 11 With one push of the power switch 17, the hob 11 is connected to the mains 24 laid.
  • the power switch 17 after a fixed safety time ts of a few seconds equal again switch off - unless within this safety period ts is still another of the switching points 15 is activated, for example via the switch 18, a cooking zone 12 selected OR via the switch 19, the cooking level of the currently selected Cooking zone 12 changed. But if a safety switch 20 is set, Thus, the locking indicator 21 lights, the hob 11 can not be turned on become.
  • the individual heating power can be by means of the cooking stage switch 19 in the manner of a mains frequency synchronized or processor-synchronized pulse width modulation influence and by means of in This realization example only existing seven-segment cooking level display 23 visualize.
  • the processor subfunction to translate the current one Degree of modulation in a numerical representation is in the block diagram of the drawing symbolized by a demodulator 26, the pulse length with respect to the cycle duration in a number between 0 (switched off) and 9 (maximum power) implements.
  • This number (23) thus indicates with which cooking level that one Cooking zone 12 is being operated, the lamp 22 is just flashing.
  • a changed one Specification of this heating power is carried out by alternative multiple or continuous operation of one of the two cooking level function switches 19- or 19+.
  • the currently still selected cooking zone 12 associated lamp 22 switches then from flashing to steady light, but while this cooking zone 12 like mentions the most recent cooking level maintained when using the selector switch 18 switched to the next of the cyclically to be selected cooking zones 12 is, so that now their zone lamp 22 is no longer constant but only still lit in the interval and the display 23 indicates their current cooking level.
  • the four separate lamps 22 are unnecessary, however, if they by four Display 23 (instead of a central one in the drawing) will be replaced.
  • the currently selected ie the currently flashing lamp 22 or display 23 marked cooking zone 12 is switched off electrically and its lamp 22nd or display 23 completely switched off when the heating power here by means of the cooking stage switch 19- is reset to zero. But if the cooking level switch 19-, 19+ not alternative, but operated simultaneously, as by the AND gate 33 symbolizes, the currently displayed the cooking zones 12 immediately switched off electrically, and their zone lamp 22 or display 23 goes out. On the other hand, via the power switch 17, a switch off of the cooktop 11 in total, that is, all of their cooking zones 12 that have just been switched on.
  • the cooking zone 12, just above the selection switch 18 to adjust their Cooking level is selected, so by a not continuously lit, but Flashing cooking zone 22 or indicator 23 shown.
  • Switching to the next cooking zone 12 with its cooking zone 22 or display 23 is performed in a cyclic sequence progressively with each short press again of the selector switch 18. With only one central display 23 refers to currently shown numerically shown cooking level indicator 23 on that cooking zone 12, the lamp 22 is not extinguished or continuously burning, but the just blinking.
  • the display 23 is switched from the demodulator 26 to the display H, if the currently selected via the switch 18 cooking zone 12 while (via the cooking level switch 19- or both 19- / 19 + simultaneously) electrically was turned off, but the geometrically associated cooking zone lamp 22 or Display 23 still does not go out, but initially still driven, because the associated cooking zone 12 still hot, namely their temperature is not yet under the order of magnitude of 50 ° C has dropped, that is still radiates a residual heat, which is harmful to the surface of human skin.
  • The is detected by means of temperature sensors 27 whose sensor signals from the processor analyzed accordingly, namely compared with a reference and, where appropriate to the (not separately designated in the drawing) drive circuits be led for the cooking zone lamps 22 and 23 displays; or a pre-set timing circuit implemented in the processor by means of counters causes this residual heat indicator to go out when the cooking zone 12 is turned off Experience has shown that it should have cooled sufficiently.
  • an extension 28 of the base control panel 14 may be of the functions (Steady light or flashing light) of the cooking zone lamps 22 functionally separated residual heat lamps 29 the cooking zones 12 geometrically assigned to be provided to the aforementioned H display 23 in the center of the cooking zone lamps 22 or one each Display 23 for the four cooking zones 12 unnecessary. If at the respective Cooking zone 12 which is critical for the risk of scorching the human skin Surface temperature is exceeded, now lights the associated residual heat lamp 29 in the control panel extension 28; being circuit technology can be specified via the processor that this light indication, for example between steady light and flashing light switches, depending on whether the associated Hotplate 12 is currently actively heated or turned off and only still residual heat leads.
  • the highest level of the booster cooker function switch 19+ is not “9” but, still above, "A”.
  • the cooking level switch 19 before selecting a certain level the display 23 is set to "A”, then is initially maximum via the currently selected cooking zone 12, corresponding to stage 9, parboiled.
  • a timer circuit 34 then switches on after the time ta to the, after the initialization via "A”, then lower predetermined cooking level back already during ta, so until you switch to continuous display under selection of this cooking zone 12, from the alphanumeric display 23 as a numeral alternately with the letter "A" is displayed.
  • At least one of the cooking zones 12 is equipped with a surface extension, for larger cookware ring-shaped or as in the illustrated embodiment as a separately switchable frying zone 30 be arcuate can.
  • a roast power switch 31 in the control panel extension 28 provided, including roaster indicator lamp 32.
  • the cooking stage setting for the roaster zone 30 takes place at the switch 19 with that for the adjacent associated cooking zone 12, which in the block diagram of the drawing is considered symbolically.
  • a tactile selection switch 18 is provided according to the invention, with a likewise palettbetätigbarer cooking level switch 19, 19- 19 + cyclically successively on each of the existing cooking zones 12 is switchable, while the other cooking zones 12 remain in their current switching state with respect to their heating. Which of the cooking zones 12 is currently heated and which of these is currently selected via the selector switch 18, results from the visual signaling of miniaturized cooking zone lamps 22 or digital displays 23, which are arranged according to the geometry of the cooking zones 12.
