Definitions

  • the invention relates to a touch switch arrangement according to the The preamble of claim 1. Furthermore, the invention relates to a method according to the preamble of claim 13.
  • touch switch arrangements Be beneficial for electrical appliances with multiple electrical consumers used.
  • the electrical consumers are adjustable with respect to their electrical power. They are selectable by a selector switch for a power setting to be made.
  • Such known touch switch arrangements are for everyone electrical load a selector switch and a plus and a minus button for the power setting on. This means that per electrical load three touch switches are necessary. This is very complex, also from the control method ago.
  • the invention is based on the object, an aforementioned contact switch arrangement and a control method for electrical appliances to create with several electrical consumers, with less Effort can be produced as well as a high operating safety guarantee.
  • the selection switch for a specific electrical Consumers also or at the same time for a performance adjustment, for example, in the plus or minus direction, are used.
  • a power adjustment can be made such that first short the selector switch is actuated to select the particular consumer.
  • a power change for example in the form of a power increase occur.
  • a common setting switch for multiple electrical loads can be provided. This further reduces the touch switch possible, namely an individual selection and power setting switch for one direction as well as a common one Setting switch for power adjustment in the other direction.
  • a common setting switch for power adjustment in the other direction.
  • the selector switch or the individual switch at least grouped around a common setting switch. This happens particularly advantageous in the form of one of the number of selection switch corresponding Polygon. As advantageous and visually and easy to use It makes sense to look at a regular polygon. It is preferably arranged in each corner of the polygon, a touch switch. The touch switches should not be too far apart, and advantageously about the same.
  • One-handed operation is for adults Persons possible with a maximum distance of 15 cm. Particularly ergonomic is a distance of about 5 cm. In this case can be a simultaneous operation of a central setting switch as well at least one selector switch as a safety barrier against be provided unintentional operation.
  • the selection switches can be associated with optical display means to display the status or switching state of the relevant electrical Consumer.
  • each selection switch assigned own display means.
  • the display means may have several different functions, in particular with respect to this electrical consumer. These Functions can include, for example, a power indicator, a hot indicator and / or a completed programming. A difference between different functions can be activated by an activation LED or special different display types of the display. Possibilities are here, for example, a flashing in different Frequencies or brightness in different stages.
  • the touch switch assembly may include at least three touch switches exhibit. These at least two touch switches are preferred distributed around a central point or area, preferably in regular arrangement or evenly distributed.
  • the display means to indicate the state of the consumer are then in the field within the arrangement of the touch switches or in the area this central point provided. They are advantageous in this case trained that the state of several consumers presented in alternation can be.
  • the display means the state of several or to indicate to all consumers. Because preferred for easy operation only the state of a consumer is displayed at the same time If a consumer's status is displayed alternately.
  • a great advantage of the invention is that for several Consumers only a single display means is provided and the effort for further display means can be saved.
  • the change of presentation can on the one hand automatically or automatically running time intervals for the different consumers respectively. It should be advantageous only displayed such consumers that are activated.
  • an illustration of the state of a particular touch switch on request, or its display set become.
  • a change the representation of the state of this consumer take place.
  • a controller a hob with several, especially four, cooking areas created become.
  • a central point or area can be a common Power adjustment switch can be arranged, as well as next to it an LED display.
  • an LED display In a substantially regular arrangement around this central point around can for each of the hobs selection switch be provided.
  • These selector switches have one to the common power setting switch complementary function. For example, with the common power setting switch the performance can be lowered, so it can with the individual Selector switch can be increased as a power adjustment function and vice versa.
  • a label for which touch switch or consumer the central display means are currently active can advantageously via a the display associated with the individual touch switch.
  • This can be an LED, for example, in a simple embodiment. It is possible to use different light intensities or possibly flashing frequencies as well as general active display as well as a selection display for this touch switch or the associated To use consumers.
  • the display means may at least in a simple embodiment have an incandescent lamp or LED. In this case, preferably several LEDs next to each other in bar, bar or circular arc form be arranged.
  • display means may include a seven-segment display exhibit. With such a so-called alphanumeric Appearance can be digits and most letters well readable and clearly shown. This allows more information are displayed.
  • the inventive method for controlling a touch switch provides that by touching the touch switch once or the sensor surface of the electrical load selected or is selected. By touching again, the electrical power be set in a certain direction. This can be a easy operation of the touch switch or setting the Consumer of the electrical appliance to be made.
  • This additional touch switch does not necessarily need a selection function, so that the device kept simpler can be.
  • a touch switch for the Power adjustment in the other direction for multiple consumers is provided jointly.
  • For a power setting is one each Consumers through the selection key to select and then the Power to be adjusted.
  • connection of a supplementary consumer belonging to the selected consumer, at a cooking place of an electric cooktop can be done by setting the highest performance level for this consumer.
  • these are Additional heaters designed as two-circuit heaters.
