Vorteilhafte Ausgestaltungen der Erfindung ergeben sich
aus den Unteransprüchen und der folgenden Beschreibung
eines Ausführungsbeispiels. In der Zeichnung zeigen:
Ein Kochfeld(K) weist vier Kochstellen(1 bis 4) auf, wobei zwei Kochstellen Zweikreis-Kochstellen sind und im Beispielsfall die vordere linke Kochstelle(1) und die hintere rechte Kochstelle(3) die Zweikreis-Kochstelle ist.A hob (K) has four hotplates (1 to 4), where two hobs are dual-circuit hobs and in For example, the front left hotplate (1) and rear right hob (3) the dual-circuit hob is.
Das Schalten bzw. Takten der Kochstellen erfolgt über Relais. Für die Zweikreis- Kochstellen ist für den 2. Kreis jeweils ein weiteres Relais(5,6) vorgesehen. Damit ist eine Leistungssteuerung möglich. Die Relais sind elektromechanische oder elektronische Relais, beispielsweise Triacs.The hotplates are switched or clocked via Relay. For the two-ring hob, the second A further relay (5, 6) is provided in each circuit. In order to power control is possible. The relays are electromechanical or electronic relays, for example triacs.
Jedes der beiden Relais(5,6) liegt an einer Logik(7,8). Diese weisen jeweils vier UND-Gatter(9 bis 12) auf, die ausgangsseitig an einem ODER-Gatter(13) liegen. Diesem ist ein UND-Gatter(14) nachgeschaltet, welches das Relais (5 bzw. 6) steuert. Zur Zeichnungsvereinfachung sind die Gatter(9 bis 14) nur in der Logik(7) dargestellt. Sie sind auch in der Logik(8) vorgesehen.Each of the two relays (5,6) is connected to a logic (7,8). These each have four AND gates (9 to 12) that lie on the output side on an OR gate (13). this is followed by an AND gate (14), which the relay (5 or 6) controls. To simplify the drawing, they are Gate (9 to 14) shown only in the logic (7). she are also provided in the logic (8).
An die einen Eingänge der vier UND-Gatter(9 bis 12) der Logiken(7,8) sind vier Relais-Steuertakte, d.h. Leistungssteuersignale, gelegt, die von einer nicht näher dargestellten, an sich bekannten Ansteuerelektronik erzeugt werden, um die Zweikreis-Kochstellen mit einer gewünschten Leistung zu betreiben. Dies ist durch die Blöcke(15 bis 18) symbolisiert.At the one inputs of the four AND gates (9 to 12) of the Logics (7,8) are four relay control clocks, i.e. Power control signals, laid out by one not closer shown, known control electronics generated to the dual-circuit hotplates with a desired performance. This is through the Blocks (15 to 18) symbolize.
An das UND-Gatter(14) ist neben dem ODER-Gatter(13) ein Ein-Ausschaltsignal für das betreffende Relais gelegt. Das Ein-Ausschaltsignal wird ebenfalls von der Ansteuerelektronik generiert, was durch den Block(19) symbolisch dargestellt ist. At the AND gate (14) is next to the OR gate (13) On-off signal for the relay concerned. The on-off signal is also from the Control electronics generates what is caused by the block (19) is represented symbolically.
Die anderen Eingänge der UND-Gatter(9 bis 12) der beiden Logiken(7,8) sind an einen Speicher(20) gelegt. Die Funktionen der Gatter(9 bis 14) lassen sich auch in anderer Weise, beispielsweise in einem Mikrocomputer verwirklichen. In diesem sind unter Adressen(A) - im Beispielsfalle "0" bis "5", die möglichen Zuordnungen der Relais(5,6) zu den Kochstellen(1 bis 4) in Form eines Bitmusters als Tabelle abgelegt. Jeder möglichen Kochfeld-Konfiguration entspricht ein eigenes Bitmuster mit eigener Adresse. Es sind so viel Adressen vorgesehen, wie es mögliche Konfigurationen gibt.The other inputs of the AND gates (9 to 12) of the two Logics (7,8) are placed on a memory (20). The Functions of the gates (9 to 14) can also be in other way, for example in a microcomputer realize. In this are under addresses (A) - in Example trap "0" to "5", the possible assignments of the Relay (5,6) to the hotplates (1 to 4) in the form of a Bit pattern stored as a table. Anyone Hob configuration corresponds to its own bit pattern with its own address. There are so many addresses how there are possible configurations.
Der Speicher(20) ist mit einem weiteren Speicher, insbesondere einem EEPROM(21) verbunden. Dieser ist mit der für die jeweilige Zuordnung vorgesehenen Adresse beschreibbar. Hierfür ist ein Bedienfeld(22), beispielsweise Sensortasten-Bedienfeld, der Kochmulde verwendbar, an dem sich die gewünschte Adresse über ein Eingabemenü anwählen läßt. Ein Ringzähler(23), der die Adressen fortlaufend nacheinander aufruft, erlaubt es, die Adressenanwahl mit nur einer einzigen Taste vorzunehmen. Für den Programmiervorgang kann eine zweite Taste (vgl. Leitung 24) vorgesehen sein.The memory (20) has a further memory, in particular connected to an EEPROM (21). This is with the address provided for the respective assignment writable. For this there is a control panel (22) for example, the sensor control panel, the hob usable at which the desired address can be found Lets you select the input menu. A ring counter (23), the Calling addresses consecutively one after the other allows address selection with just one button make. A second can be used for the programming process Button (see line 24).

Leitung a), so daß der Relaistakt für die Kochstelle(1) (vgl. Block 15), speziell deren 2. Kreis, auf das Relais(5) und damit die Kochstelle(1) geschaltet wird, wenn vom Block(19) das Einschaltsignal an das UND-Gatter(14) gelegt ist.In the example, the hotplates (1 and 3) should be the Be a two-ring hob. A "one" of the bit pattern the address "3" of the memory (20) is the AND gate (9) assigned to the logic (7) (cf. line a), so that the Relay clock for the hotplate (1) (see block 15), especially their 2nd circuit, on the relay (5) and thus the Cooking point (1) is switched when the block (19) Switch-on signal is applied to the AND gate (14).
Außerdem ist eine "Eins" des Bitmusters der Adresse "3" dem UND-Gatter (11) der Logik(8) zugeordnet (vgl. Leitung b), so daß der Relaistakt für die dritte Kochstelle(3) (Block 17), speziell deren 2. Kreis, auf das Relais(6) und damit die Kochstelle(3), speziell deren 2. Kreis, durchgeschaltet wird, wenn das entsprechende Einschaltsignal vorliegt.In addition, a "one" of the bit pattern of address "3" assigned to the AND gate (11) of the logic (8) (cf. line b), so that the relay clock for the third hotplate (3) (Block 17), especially their 2nd circuit, to the relay (6) and thus the hotplate (3), especially its 2nd circle, is switched through if the corresponding Switch-on signal is present.
Es ist also erreicht, daß dann, wenn nach der Montage der Kochmulde über das Bedienfeld(22) im EEPROM(21) die Adresse "3" angewählt wird, im Betrieb die für die Zweikreis-Kochstelle(1) erzeugten Relaistakte die Kochstelle(1), speziell deren 2. Kreis, und die für die Zweikreis-Kochstelle(3) erzeugten Relaistakte die Kochstelle(3), speziell deren 2. Kreis, steuern.It is therefore achieved that if after the assembly of the Cooking hob via the control panel (22) in the EEPROM (21) Address "3" is selected, in operation the for the Dual circuit hotplate (1) generated the relay clocks Cooking area (1), especially its 2nd circle, and that for the Dual circuit hotplate (3) generated the relay clocks Control the hotplate (3), especially its 2nd circle.
Bei der in der Figur 2 im Speicher(20) dargestellten Bitmusterverteilung wird die Adresse "0" dann angewählt, wenn der Kochmuldentyp so ist, daß die Kochstelle(4) die Zweikreis-Kochstelle ist und deren 2. Kreis vom Relais(5) angesteuert werden soll.The one shown in FIG. 2 in the memory (20) Bit pattern distribution, the address "0" is then selected, if the hob type is such that the hob (4) the Dual-circuit hotplate and its 2nd circuit from the relay (5) should be controlled.
Die Adresse "1" wird angewählt, wenn der Kochmuldentyp so ist, daß die Kochstelle(3) die Zweikreis-Kochstelle ist und deren 2. Kreis vom Relais(5) und die Kochstelle(4) die Zweikreis-Kochstelle ist und deren 2. Kreis vom Relais(6) angesteuert werden soll.The address "1" is selected if the hob type is this is that the hotplate (3) is the two-circuit hotplate and its 2nd circuit from the relay (5) and the hotplate (4) is the two-ring hob and its second circle from Relay (6) should be controlled.
Die Adresse "2" wird angewählt, wenn die Kochstelle(2) die Zweikreis-Kochstelle ist und deren 2. Kreis vom Relais(5) angesteuert werden soll.The address "2" is selected when the hotplate (2) is the two-ring hob and its second circle from Relay (5) should be controlled.
Die Adresse "4" wird anwählt, wenn die Kochstellen(3,4) die Zweikreis-Kochstellen sind und das Relais(5) der Kochstelle(3) und das Relais(6) der Kochstelle(2) zugeordnet werden soll.The address "4" is selected when the hotplates (3,4) the dual circuit hotplates and the relay (5) are the Hotplate (3) and the relay (6) of the hotplate (2) should be assigned.
Die Adresse "5" wird angewählt, wenn die Kochstellen(1,2) die Zweikreis-Kochstellen sind und das Relais(5) der Kochstelle(2) und das Relais(6) der Kochstelle(1) zugeordnet werden soll. The address "5" is selected when the hotplates (1,2) the dual circuit hotplates and the relay (5) are the Hotplate (2) and the relay (6) of the hotplate (1) should be assigned.
Die Logik des Eingabemenüs und der Entschlüsselung der speichergesteuerten Relaiszuordnung sind mittels eines Mikrocomputers realisierbar. Der EEPROM(21) und der Speicher(20) können Teil eines Mikrocomputers sein, wobei der Speicher(20) selbst auch Teil des EEPROMS(21) sein kann. Es ist dann eine freie Programmierbarkeit der genannten Bitmuster möglich, wodurch beispielsweise neue Kochfeld-Konfigurationen eingespeichert und/oder nicht verwendete Konfigurationen gelöscht werden können.The logic of the input menu and the decryption of the memory-controlled relay assignment are by means of a Microcomputers can be implemented. The EEPROM (21) and the Memory (20) can be part of a microcomputer, wherein the memory (20) itself can also be part of the EEPROM (21) can. It is then freely programmable mentioned bit pattern possible, which, for example, new Hob configurations saved and / or not used configurations can be deleted.
In der beschriebenen Weise läßt sich nicht nur die Zuordnung der Leistungssteuersignale zu den Kochstellen wählen; es ist auch die Zuordnung weiterer Funktionen zu Kochstellen möglich.In the manner described, not only can Assignment of the power control signals to the hotplates choose; it is also assigning additional functions to it Cooking areas possible.
Die beschriebene Zuordnung kann auch dann vorgesehen sein, wenn eine der Kochstellen auf eine besonders hohe Leistung ausgelegt ist. Für diese Kochstelle ist ein Leistungsrelais nötig, das diese besonders hohe Leistung schalten kann. Je nach dem Kochmuldentyp kann diese Kochstelle die Kochstelle(1,2 oder 3 oder 4) sein. Die übrigen Kochstellen sind auf kleinere Leistungen ausgelegt. Sie können dementsprechend mit leistungsschwächeren Relais arbeiten. In der beschriebenen Weise werden dann die für die stärkste Kochstelle vorgesehenen Relaistakte über das Leistungsrelais auf diese geschaltet. Die anderen Kochstellen werden entsprechend über die anderen Relais betrieben. Von Vorteil ist dabei, daß nur ein Relais als Leistungsrelais ausgebildet sein muß, was die Kosten für die Relaisanordnung erheblich reduziert. Wäre die Zuordnungsmöglichkeit nicht gegeben, dann müßten alle vier Relais als Leistungsrelais ausgelegt werden, um die Anschaltbarkeit an die verschiedenen Kochmuldentypen zu gewährleisten.The assignment described can also be provided be when one of the hotplates is at a particularly high level Performance is designed. There is a for this hotplate Power relays necessary, this particularly high performance can switch. Depending on the type of hob, this can Hotplate is the hotplate (1, 2 or 3 or 4). The other cooking zones are on smaller services designed. Accordingly, you can use less powerful relays work. In the described ways will then be the strongest Relay clocks provided via the hotplate Power relay switched on this. The others Cooking areas are switched accordingly via the other relays operated. The advantage here is that only one relay as Power relays must be trained in what the cost of the relay arrangement significantly reduced. Would that be Not possible to assign, then everyone would have to four relays can be designed as power relays to the Can be connected to the various types of hob guarantee.
