Description

Befehlseingabe für das elektronische Programm-Steuerwerk einer Wäschebehandlungs- oder GeschirrspülmaschineCommand input for the electronic program control unit of a laundry treatment or dishwasher

Die Erfindung "bezieht sich auf eine Anordnung zur Befehlseingabe mittels kapazitiv gekoppelter Sensortasten für das elektronische Programmsteuerwerk einer Wäschebehandlungs- oder Geschirrspülmaschine u. dgl.The invention "relates to an arrangement for entering commands by means of capacitively coupled sensor keys for the electronic program control unit of a laundry or dishwasher and the like

Bei Haushaltsmaschinen der vorgenannten Art werden mehr und mehr elektronische Steuerwerke eingesetzt, die es erforderlich machen, geeignete Anordnungen zur Befehlseingabe für diese Geräte zu schaffen.Electronic control units are being used more and more in household machines of the aforementioned type, which make it necessary to create suitable arrangements for entering commands for these devices.

Hier liegt es nun nahe, auf die aus der Unterhaltungselektronik bereits bekannten Bedienungssysteme zurückzugreifen. Besonderer Beliebtheit haben sich auf diesem Gebiet die Berührungsplattenfelder erfreut, deren Sensortasten bei Berührung mit einem Finger durch Kapazitätsänderung oder ohmscher Widerstandsänderung einer Schaltungsanordnung einen entsprechenden Schaltvorgang auslösen.Here it makes sense to fall back on the operating systems already known from entertainment electronics. The touch panel fields have enjoyed particular popularity in this area, their sensor buttons when touched with a finger due to a change in capacitance or ohmic change in resistance a circuit arrangement trigger a corresponding switching process.

Die von der Unterhaltungselektronik her bekannten Eingabevorrichtungen konnten jedoch bei den Haushaltsgeräten der eingangs genannten Art nicht direkt übernommen werden, da hier erhebliche, konstruktive Hindernisse im Wege standen und da die erforderlichen Sicherheits- und Schutzbestimmungen mit den bekannten Anordnungen nicht erfüllt werden konnten.The input devices known from consumer electronics could, however, be used in household appliances of the type mentioned above cannot be taken over directly, as there were significant, constructive obstacles in the way and there the necessary safety and protection regulations could not be met with the known arrangements.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zur Befehlseingabe mittels kapazitiv gekoppelter Sensortasten für das elektronische Programmsteuerwerk einer Wäschebehandlungs- oder Geschirrspülmaschine zu offenbaren, die in den vorgenannten Geräten einwandfrei arbeitet, einen einfachen Aufbau besitzt mit entsprechender Servicefreundlichkeit und die die erforderlichen Sicherheits- und Schutzvorkehrungen berücksichtigt.The invention is based on the object of providing an arrangement for inputting commands by means of capacitive coupled sensor buttons for the electronic program control unit of a laundry treatment or To reveal dishwasher that works properly in the aforementioned devices, a simple structure with appropriate serviceability and the necessary Safety and protection precautions taken into account.

Die Lösung dieser Aufgabe wird durch die im Hauptanspruch erfindungsgemäß dargelegte Anordnung erzielt.This object is achieved by the arrangement set out according to the invention in the main claim achieved.

Weitere Merkmale der Erfindung ergeben sich aus dem nachgestellten Unteranspruch und aus der nachfolgenden Beschreibung.Further features of the invention emerge from the subsequent dependent claim and from following description.

Eine vorteilhafte und bevorzugte Ausbildung der Erfindung ist in den Zeichnungen schematisch dargestellt.An advantageous and preferred embodiment of the invention is shown schematically in the drawings shown.

Fig. 1 eine Waschmaschine in Frontansicht,1 shows a washing machine in front view,

Fig. 2 in einer Detailzeichnung eine einzelne Befehlseingabe-Anordnung im Schnittaufbau.2 shows a detailed drawing of an individual command input arrangement in a sectional structure.

In der Fig. 1 ist als Anwendungsbeispiel für die erfindungsgemäße Befehlseingabe-Anordnung eine Waschmaschine 1 gewählt.In Fig. 1 is an application example for the command input arrangement according to the invention Washer 1 selected.

In ihrer Schalterblende 2 befindet sich ein Sensor-Tastenfeld 3 mit einzelnen, berührungswirksamen Sensortasten 3'· Durch Fingerberührung dieser Sensortasten 3' kann die Anwahl des gewünschten Waschprogramms erfolgen.In its switch panel 2 there is a sensor keypad 3 with individual touch-sensitive Sensor buttons 3 '· By touching them with your fingers The desired washing program can be selected using the 3 'sensor buttons.

Der Aufbau der Befehlseingabe-Anordnung geht aus der schematisch gehaltenen Fig. 2 im Detail anhand einer einzelnen Sensor-Eingabe hervor. Auf der Schalterblende 2 oder in der Schalterblende 2 eingelassen befindet sich die Sensortaste 3'. Diese Sensortaste 3' wird bei Anwahl mit dem Finger' berührt. Hinter der Schalterblende 2 ist eine Leiterplatine 4 in einem nicht näher dargestellten Schaltungsmodul angeordnet. Die Leiterplatine 4 trägt jeweils gegenüberliegend die für das kapazitive Schaltprinzip notwendigen Kcndensatorelektroden und 5f. Die Leiterplatine 4 selbst bildet dabei das Dielektrikum, und sie ist vorzugsweise mindestens 2 mm stark.The structure of the command input arrangement is shown in detail in FIG. 2, which is kept diagrammatic, based on a single sensor input. The sensor button 3 'is located on the switch cover 2 or in the switch cover 2. This sensor key 3 'is touched with the finger' when it is selected. Behind the switch panel 2, a printed circuit board 4 is arranged in a circuit module not shown in detail. The printed circuit board 4 carries the capacitor electrodes and 5 f, which are necessary for the capacitive switching principle, opposite each other. The printed circuit board 4 itself forms the dielectric, and it is preferably at least 2 mm thick.

Die elektrisch leitende Verbindung von der Sensor-Taste 3! zur Kondensatorelektrode 5 wird durch eine Kontaktfeder 6 hergestellt. Die Leiterplatine 4 mit ihren Kondensatoren ist in Modultechnik durch geeignete Steckverbindung mit der nicht weiter gezeigten Schaltungselektronik verbunden.The electrically conductive connection from the sensor button 3 ! to the capacitor electrode 5 is produced by a contact spring 6. The printed circuit board 4 with its capacitors is connected to the electronic circuitry, not shown further, using modular technology by means of a suitable plug connection.
