Definitions

  • the present invention relates to an operating arrangement for operating an electrical device, in particular a household appliance, with a diaphragm made of an electrically insulating material which has an inner side and an operating side, and with a sensor arrangement for detecting an object on the operating side, wherein the sensor arrangement comprises a printed circuit board and a sensor element disposed on the inside of the diaphragm, which are electrically connected to each other by means of a contact arrangement, wherein the sensor element is made of an electrically conductive material and connected to the diaphragm.
  • Such an operating arrangement is known, for example, from WO 2006/034993 A1.
  • a spring element is arranged between a printed circuit board and the inside of an insulating plate (diaphragm).
  • the spring element is designed as a helical compression spring and has at the end facing the diaphragm to a spirally wound portion which bears against the inside of the diaphragm.
  • Capacitive touch switches have long been known. For the realization of control surfaces of glass ceramic cooktops, it is known, for example, from DE 80 33 570 U1 to provide a large capacitor area on the upper surface and two smaller capacitor surfaces on the rear side of the glass ceramic plate. In a smaller capacitor area, an alternating current is fed. An alternating current is taken from the other small capacitor area. By a finger arranged on the operating side of the capacitive arrangement is detuned, which can be evaluated by a suitable evaluation and recognized as "operation" of the capacitive touch switch.
  • a further embodiment of a capacitive touch switch is known from document EP 1 416 636 A2, in which a foam body has electrically conductive regions with a sensor element surface and insulating regions which are provided alternately in the direction of extension of a glass ceramic plate. This creates a kind of "strand material" from which adjacent capacitive touch switches can be made.
  • the sensor element is formed as a planar element which extends over a length which is at least twice as long as the thickness of a human finger.
  • Such a sensor element can be produced inexpensively and connect structurally favorable with the aperture. Furthermore, it is possible by the relatively large extension in the length direction to realize not only a switch function by means of the sensor element, but a plurality of switch functions and / or a kind of slider (potentiometer).
  • the contact arrangement has at least one contact section which connects the sensor element at one end to the printed circuit board.
  • the contact arrangement has at least one contact section which connects the sensor element at one end to the printed circuit board.
  • the contact arrangement has at least one contact section which connects the sensor element at one end to the printed circuit board.
  • the at least one contact section is formed integrally with the sensor element.
  • the sensor element has at least one impedance variation section over its length, by means of which the impedance of the sensor element is influenced in such a way that surfaces associated with the impedance variation section can be distinguished from one another as discrete control surfaces.
  • an impedance changing section by means of an impedance changing section, a kind of resistance jump is locally realized in the sensor element, which in turn serves to better distinguish between discrete operating surfaces. This is useful in the evaluation of signals that are tapped from the ends of the sensor element. That is, the impedance changing section causes a signal jump if an object (finger) is moved over the length of the sensor element and over such an impedance varying section.
  • the impedance changing section is formed by changing the width of the sensor element.
  • the impedance changing section is formed by a step section, in which the sensor element has a step emerging from the surface.
  • a step section can also be combined with a variation of the width of the sensor element.
  • the circuit board is held by holding means at a predetermined distance from the inside of the diaphragm, wherein the contact arrangement has at least one contact portion which is formed elastically in the direction of the distance, and / or wherein the circuit board is resiliently biased or of the holding means is held elastically.
  • This measure ensures that the electrical resistance at the transition from the sensor element to the contact section and / or from the contact section to the circuit board is kept as low as possible. As a result, a signal corruption can be avoided. In particular, it can be achieved that no air gap arises between the sensor element and the contact section or between the contact section and the printed circuit board, which would considerably increase the capacitance and considerably complicate the evaluation of signals.
  • the contact section has an elastic element such as a spring.
  • the contact portion is formed either as a separate element from the sensor element or an elastic E element (such as a spring, a foam element, a TPE element, etc.) is integrally formed on the sensor element and integrally formed therewith.
  • an elastic E element such as a spring, a foam element, a TPE element, etc.
  • the material of the sensor element and a contact portion integrally connected thereto are elastically deformable.
  • the contact portion does not necessarily have a spring shape, but may also be solid or formed as a hollow portion.
  • the sensor element lies flat against the inside of the panel.
  • a dielectric in the form of the material of the diaphragm is realized between the sensor element and the operating side of the diaphragm, which forms a part of the capacitor between the sensor element and a finger touching the operating side.
  • no air gap is present between the planar sensor element and the inside of the diaphragm.
  • it can be safely distinguished between a state in which the finger is spaced from the operating side (in which case there is an air gap with a relatively low dielectric constant between the finger and the diaphragm), and a state in which the Finger touches the operating side of the diaphragm (in which case between the finger and the sensor element only acting as a dielectric diaphragm of the electrically insulating material is present, which preferably has a clearly higher dielectric constant).
  • the sensor element is integrated as a conductive portion in the diaphragm.
  • the outside of the sensor element makes it possible for the outside of the sensor element to be directly accessible in the region of the diaphragm or from its operating side. This may possibly lead to improved detection sensitivity and / or evaluability. It is conceivable that the sensor element and the diaphragm are integrated with each other such that a substantially continuous or flush operating side is formed. It is also preferable if the integration is such that the interface between the Sensor element and the diaphragm is impermeable to liquids and / or gases.
