Definitions

  • the invention relates to a device for switching a electric heating with at least two heating areas that variable with electrical via at least one power controller Performance is taxable for the at least one power controller and with functional from each other separate switching means for actuating the at least a power controller via the control means. Is preferred such a device used in electrical heating devices, especially for the household.
  • Such devices are known in which two switching means provided for switching a heater on or off are.
  • One of the two switches serves as a so-called Release switch, after its actuation within the actuation of the second at a certain time interval Switch must follow. By pressing the second The heater is then switched on. By renewed The heater can be operated again by pressing the first switch turned off. It has also been proposed for connecting several heating areas of a heater to proceed similarly.
  • a switch is a release switch while with a second switch the different Heating areas switched on in sequence can be.
  • the invention has for its object to a device create a quick and easy switching of different Heating areas according to a user's request enables, versatile, reliable and is easy to manufacture.
  • Each switching means is preferably precise via the control means assigned a heating area.
  • An adjustment is preferably made by power controller, in particular one each associated power controller. In this way it is possible a desired with just one actuation of a switching means Setting the heating area directly, which is both effort and possible incorrect operations are also reduced.
  • Preferred the control means the heating area when actuated for the first time a switching means for this heating area.
  • control means with repeated or double actuation the same switching means a part of the heating areas, preferably turn off all connected heating areas.
  • Prefers does not find any intermediate between the two operations Change in the loading of the heating areas with electrical power and / or actuation of one of the switching means instead of. If a different heating range has been set, so is now the new, corresponding to the actuated switching means, Heating area set.
  • the switching means and / or the heating areas are preferred hierarchically structured, in particular there is one Classification from low to high. Alternatives are others Outlines possible, even if this is the preferred one.
  • One mode of operation can provide that the control means at Actuation of a switching means of a heating area in a higher level than the currently set level Raise level. Thereby, steps below be turned off, preferably put the control means below however, lying steps. That means that through an actuation of a certain switching means the heating area as well as all the underlying heating areas or can be switched on.
  • the heating areas are spatially or extensively extended heating zones his.
  • they are an additional heating zone of a basic heating zone assigned to the heater, preferably on border the basic heating zone.
  • the basic heating zone can be changed from the Additional heating zones should be essentially surrounded by either each additional heating zone or several or their entirety.
  • a possible hierarchical order of the heating areas in Different levels can be the spatial assignment of the additional heating zones correspond to the basic heating zone.
  • the additional heating zones increase depending on From their size in stages, an increasing one is preferred Distance from the basic heating zone is the reason for the increase placed.
  • a Heating one in a round hob of an electric cooker have arranged basic heating zone, the additional heating zones form an enlargement of the heatable area can, preferably adjacent to one side as an extension and / or essentially surround the basic heating zone. Possible this is for example an electric stove with four Hobs, one of which is concentrically larger heatable Circular areas for particularly large cooking vessels and one each of the additional heating zones located on the opposite side for roasters or the like.
  • a connection between the heating of the heater and the Heating areas can consist of a performance with which is applied to at least one of the additional heating zones a power application of the basic heating zone is adjusted.
  • the heating areas can be used as an alternative to additional heating zones different heating power levels. Are there the power levels, in particular in increasing order, preferably from 0 to maximum.
  • a heater would be included gradually adjustable power and a number of Switching means, each of which corresponds to a power level.
  • the desired power level is set in not in this case, as is the case with known electric cookers with a rotary knob, but by pressing the respective switching means.
  • Display means can be assigned to each switching means, preferably in close proximity to the switching means.
  • the control means can the display means of the currently set Activate the heating area, preferably only the Display means of this heating area.
  • the display means of other possibly set, heating areas of this heater preferably not set.
  • a display means preferably preferably uses an optical display, for example a light indicator, preferably with light bulbs or particularly preferably realized with light-emitting diodes.
  • Touch switches are suitable as switching means, preferably on a capacitive basis. They are preferably under one Cover attached, for example a glass ceramic hob. Touch switches with a are particularly preferred spatially extended and flexible sensor body, which is changeable in space. Touch switch this Art are for example in the German patent application 197 06 168.0.
  • Mechanical switches can be used as power controllers be, preferably electromechanical switches. Suitable are, for example, power relays.
  • the control means can have a microprocessor which preferably with a memory for operating states and / or Parameter is connected or contains it. In this case the switching means deliver a signal that a switching operation was triggered.
  • the microprocessor can perform other functions take. It is also possible to add further switching means Assign functions, for example to change the Configuration of the entire facility or an electrical heating device.
  • the drawing shows a schematic device for Switching a heater with several heating zones via one two microprocessor-connected touch switches.
  • the drawing shows a switching device according to the invention 11 for switching an electric heating device 12, which for example a radiant heater of a glass ceramic cooktop can be.
  • the switching device 11 has switching means a touch switch 14 and another touch switch 16 on.
  • the first touch switch 14 is an optical signal indicator 15 assigned, as well as the second Touch switch 16 a second signal display 17th
  • the heater 12 shown schematically, has one Basic heating zone 25, a first additional heating zone 27 and one second additional heating zone 29.
  • the additional heating zones 27 and 29 surround the basic heating zone 25 roughly concentric. Refinements are also possible at those additional heating zones on the side of a basic heating zone connect. Combinations of surrounding and Additional heating zones on the side possible. It is the shape of the heating zones is by no means essentially round Refinements limited.
  • the first and second touch switches 14 are connected and 16 with control means in the form of a microprocessor 19, as well as the displays 15 and 17. Furthermore, the microprocessor 19 connected to input means 20, which are shown in the Example of setting the level of electrical Power that is applied to the heater 12 serve.
  • the microprocessor 19 has a power controller 22 connected.
  • This power controller 22 consists of several Switching units 23.
  • Each of the two additional heating zones 27 and 29 has its own switching unit 23 with which it by means of a first additional connection 28 and a second Additional connector 30 are connected.
  • the basic heating zone 25 is with a connection 26 to its own switching unit 23rd connected.
  • the switching units 23 of the power controller 22 can be trained that all heating zones of the heating device 12 applied with the same, adjustable power level become.
  • the switching units 23 of the first and the second additional heating zone 27 and 29, for example, as a simple one On / off switch is formed while the switching unit 23 the basic heating zone 25 is the power level for the entire Heating device 12 determines.
  • the switching units 23 be designed differently, for example as electromechanical Switches or power relays. Especially for Induction heaters can power electronic components be used.
  • An advantageous functional sequence made possible by the invention in an exemplary use in a hotplate an electric cooker can work as follows.
  • About the Input means 20 becomes a certain power level of the basic heating zone 25 set.
  • a user operates the first touch switch 14, the first optical signal indicator lights up 15 and the microprocessor 19 releases the switching unit 23 the first additional heating zone 27.
  • Via the additional connection 28 is then just like the basic heating zone 25 with one Power supply connected, they have the same power level exhibit. In this way, the heated area of the Heating device 12 significantly enlarged.
  • both additional heating zones 27 and 29 are activated, the second touch switch 16 is actuated, the microprocessor 19 switches off both additional heating zones, both signal indicators 15 and 17 go out and only that Basic heating zone 25 remains switched on.
  • the first touch switch 14 is actuated, the corresponding to this switch Condition set. That means all higher ones Additional heating zones, in this case the additional heating zone 29, be turned off.
  • the signal display 17 goes out and the Signal display 15 lights up. Press the first one again Touch switch 14 also switches the first additional heating zone 27 from.
  • the heating areas can not only protrude described spatial heating zones as an extension of a Heating device, but also different power levels, especially a single heater. Similar to above can be described by pressing the appropriate Switching means or touch switches instead of flat ones Heating zones a heating or power level can be set. For example, if you consider the heater 12 as one only heating and heating zones 25, 27 and 29 accordingly as levels I, II and III, i.e. increasing power levels, introduces, so that described above Functional scheme can be adopted directly. Further explanations can therefore be omitted.
