Definitions

  • the invention relates to an operating device for a domestic appliance, which comprises at least two piezoelectric sensors, which are arranged in a housing made of metal.
  • the operating device comprises a metal strip, under which a plurality of sensors are arranged, which may also be designed as piezoelectric sensors. These piezo sensors are encapsulated by a potting compound made of plastic in recesses which are formed on the underside of the control bar. As a result, each individual piezo sensor is decoupled and also completely isolated from the metal housing.
  • the piezoelectric sensors are only relatively far from each other attachable and beyond the production is relatively complex.
  • the introduction of the potting compound and the positioning of the piezoelectric sensors is relatively complex and therefore costly.
  • the functionality of the operating device is limited, since in this regard, the realization of a slider with piezoelectric sensors can be met only very inadequate. With regard to the realization of a slide control, this means that on the user interface of the operating device, a setting is made to the effect that with a setting over a certain actuation path is a touch.
  • the piezo sensors are connected to a same electrical potential.
  • the simplification of the operating device can be made possible and the precise evaluation of the signals are possible.
  • a realization can be made possible by this embodiment, in which the operating device can also be designed according to a slide control and yet includes a plurality of separate piezoelectric sensors thereto. Because of the design to the effect that the piezoelectric sensors are at the same electrical potential, here too the electrical decoupling can be virtually guaranteed and a separate electrical insulation, for example by a potting compound, is no longer necessary. It can thus be arranged without insulating intermediate webs in the metal housing, the piezoelectric sensors. This can also be made possible that the distance between the piezoelectric sensors is reduced, which in turn the realization of a slide control with piezo sensors can be achieved.
  • the piezoelectric sensors are connected to ground potential and thus are set to ground potential.
  • This reference potential offers the simplest and safest design in terms of circuit design, reliability and reliability.
  • the piezoelectric sensors are connected in the evaluation of an actuation of a piezoelectric sensor with a same electrical potential.
  • a realization can then be made possible in such a way that all piezo sensors with one connection are at the same potential.
  • an electrical insulation between a piezoelectric sensor and the metal profile of the housing is no longer necessary.
  • the piezoelectric sensors are permanently connected to the same electrical potential during operation of the operating device.
  • the evaluation is realized by a matrix evaluation.
  • the piezoelectric sensors are arranged at a distance from one another and the space between the piezoelectric sensors is formed free of insulating material. In this space thus no electrical insulation material is arranged.
  • At least two piezoelectric sensors of the operating device arranged on a metal housing are at least temporarily connected to a same electrical potential.
  • the piezoelectric sensors are set to an identical electrical potential at least in the evaluation of an actuation of a piezoelectric sensor.
  • the piezoelectric sensors are connected to ground potential.
  • FIGURE shows a perspective view of a hob with a control device according to the invention.
  • the hob 1 domestic appliance is in a worktop 2, in particular in a section of the worktop 2, arranged.
  • the hob 1 comprises a cooking plate 3, which is formed of glass ceramic.
  • cooking zones 4, 5, 6 and 7 are formed, which are heated by arranged under the hotplate 3 heaters.
  • preparation vessels for preparing food can be placed.
  • the hob 1 further comprises an operating device 8, which is arranged in the embodiment on the front side of the cooking plate 3 and is formed like a strip.
  • the operating device 8 comprises a metallic operating strip 9, under which a plurality of piezoelectric sensors 10, 11, 12, 13 and 14 are arranged.
  • the number of piezoelectric sensors 10 to 14 is merely exemplary and in the exemplary embodiment, only the piezoelectric sensors 10 to 14 are identified by reference numerals.
  • the control bar 9 comprehensive metal housing of the control device 8 is also provided for receiving the piezoelectric sensors 10 to 14.
  • These piezoelectric sensors 10 to 14 are incorporated in the metal housing and in particular in recesses of the control bar 9 without additional electrical insulating material. In particular, this is in this No potting compound and no other electrically insulating intermediate webs between the piezoelectric sensors 10 to 14 are arranged.
  • the key evaluation of the piezoelectric sensors 10 to 14 carried out via a matrix evaluation is realized in such a way that all piezoelectric sensors 10 to 14 with an electrical connection are at the same electrical potential.
  • the present arrangement is at ground potential. As a result, functional isolation between the piezoelectric sensors 10 to 14 and the metal profile is no longer necessary.
