Definitions

  • the invention relates to an operating device for an electrical appliance with touch switches, which are arranged under a cover. It also relates to a method for connecting an additional heater to a heater.
  • the invention has for its object to provide an aforementioned operating device and an aforementioned method, which are eliminated with the problems of the prior art can and in particular a better use of sensor elements with less effort and safe operation is possible.
  • At least two markings are provided or attached over each areal sensor element, namely different markings or markings for different conditioning functions or for at least two sensor element functions.
  • At least one marking is arranged outside the center of gravity of the sensor element surface. If one marking is arranged approximately above the center of gravity of the sensor element and the other outside thereof, the application of a finger to the markings produces signals of different strength or signal changes on the sensor element, which can be detected for evaluation the said sensor element function is.
  • the signal or signal change is relatively large.
  • the signal or the signal change is significantly smaller.
  • the electric field formed over the sensor element depends on the surface or is influenced by it. This electric field changes at least in the case of capacitive sensor elements by approaching or placing a finger.
  • two different operating functions or sensor element functions can be taken over, so to speak, with constant evaluation electronics and evaluation methods with only a single sensor element.
  • it may even be more. This corresponds approximately to the replica of a plurality of virtual sensor elements, which is achieved by the respective spatial arrangement of sensor element and marking each other.
  • a sensor element it is possible for a sensor element to have a substantially rectangular or circular shape, that is to say a surface which is as compact as possible, which is, so to speak, the opposite of elongated or branched.
  • a marking is arranged approximately in the middle region.
  • the other marking is rather arranged relatively close to the edge region of the sensor element surface. For example, it is positioned so close to the edge that the average touch surface resulting from contact with a finger extends beyond the edge of the sensor element when the contact is centered on the label. This average contact area may be about 8mm to 12mm.
  • the absolute proportions of the sensor element should be such that with these aforementioned average contact surfaces by an applied finger, the markings are positioned, in particular that outside the center of gravity of the sensor element surface, that the contact surface protrudes beyond the edge of the sensor element surface.
  • the sensor element has an elongated shape.
  • a marking is mounted approximately above or above the sensor element in such a way that a contact surface resulting from contact with a finger lies fully within the sensor surface.
  • Another label may be appropriate for a similar one Touching surface protrudes at least partially beyond the edge of the sensor element.
  • the sensor element surface may have differently sized partial surface areas. Different markings are arranged over differently sized sub-area areas, although this may well be either concentric or above the center. Due to the different sized sub-area areas different sized signals or signal changes are generated on the entire sensor element, which can be registered by a control or signal evaluation as each corresponding actuation.
  • the invention is very good if three or even only two different functions are provided or three or two different positions of labels are provided to a sensor element surface.
  • the sensor element may have a larger partial area, which is followed by at least one smaller partial area.
  • An identification can then be arranged above the centroid of each partial surface.
  • a taper or waisted shape can be provided between individual sub-areas of a sensor element. This is considerably narrower than the width of the small sub-areas, so that they can not predominantly contribute to the active area of the sensor element or the respective subarea.
  • This connection region then essentially represents the electrical connection of the individual partial surfaces or causes the sensor element to be electrically connected in total.
  • a smaller partial area may be provided for the sensor element, to which two larger partial areas are attached. shut down. These may be provided in particular at opposite ends of the smaller partial area. Again, the smaller part of the area can be considered as a kind of elongated waist or narrow connection area between the two larger faces. Alternatively, the smaller partial surface in turn may be connected by even narrower connections with the larger partial surfaces.
  • the operating device or operating functions implemented thereby that the operating functions provided by the different markings on one and the same sensor element are complementary to one another.
  • this is for example a kind of plus function for increasing a power or increasing a predetermined value and a minus function for reducing this power or this value.
  • the advantage of realizing just such complementary functions is that if you set too much or change in one direction only a small amount of finger movement is necessary to correct it.
  • sensor elements are then not made much larger than necessary, so that the different markings are not too far apart or approximately with a distance which is two to a maximum of five times the diameter with an aforementioned contact surface.
  • For connecting the sensor element or for electrical contacting it is sufficient to provide a single connection. This can be provided at any point depending on the design of the sensor element. It is advantageous, in particular in the case of sensor elements which are not optimally electrically conductive, from a region between two partial surfaces.
  • the individual markings can still be closer together than in the usual, since no signal to noise ratio between different sensor elements is necessary. It is also possible to provide lighting means for indicating the operating state of the operating device or of the electrical appliance in the vicinity of the sensor element.
  • an additional heating device to a heating device in an electrical appliance, which may be, for example, an oven or a hob and have a previously described operating device, in a new way.
  • the heater is started after selection or selection via a first actuation of a minus button for power reduction, so an operator to understand that no particularly high performance is desired. Thus, experience has shown that no additional heating device is required.
  • the auxiliary heater is deactivated. If, on the other hand, the heater is started via a first confirmation of a plus key to increase the power, obviously higher powers are desired. Accordingly, the auxiliary heater, which usually heats an even larger area than the already existing base heater, activated.

Abstract

L'invention vise à simplifier la construction et l'évaluation d'éléments de détection (20a) dans un dispositif de commande (11). A cet effet, les éléments de détection sont conçus de manière à présenter des surfaces partielles (22a, 24a, 26a) de tailles différentes. L'application d'un doigt sur un capot (13) recouvrant l'élément de détection (20a), en fonction d'un imprimé (15, 16) prévu sur le capot, crée une surface tactile sur l'élément de détection (20a). Un signal de commande d'intensité variable est alors déclenché et peut être affecté à une fonction de commande correspondante.
