Definitions

  • the invention relates to a circuit for assigning Power control signals of control electronics Cooking areas of a hob.
  • the hob of a particular cooker or Cooking hob type has several cooking zones.
  • the hotplates different maximum heating output, for example 1.8 kW or 2.3 kW, and as Single-circuit or dual-circuit cooking zones can be designed.
  • At different types of cooker or hob are the Cooking areas distributed differently on the hob. In a simple example is one Cooking hob type a two-ring hob where, at another type of hob, a single-ring hob is provided.
  • the different types of cookers have so different configurations of the hotplates of the respective hob.
  • the power control signals for the hotplates are at modern cookers or hobs from one Control electronics generated.
  • the correct assignment of the Power control signals to the hotplates can be transmitted through a appropriate wiring done.
  • At different types of cooktop are different Wiring necessary, what the assembly of the hob makes expensive.
  • the assignment using software or Making coding plugs also has disadvantages because then different for different types of cooktop Software variants used or coding plug installed Need to become. In all of these cases the assignment is predefined without being changed during assembly can be.
  • the object of the invention is a circuit of the input to propose the type with which the assignment at easy to assemble and according to the respective conditions of the hob to be assembled can be made.
  • the above object is characterized by the features of characterizing part of claim 1 solved.
  • 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.
  • the hotplates are switched or clocked via Relay.
  • the second A further relay (5, 6) is provided in each circuit.
  • the relays are electromechanical or electronic relays, for example triacs.
  • Each of the two relays (5,6) is connected to a logic (7,8). These each have four AND gates (9 to 12) that are on the output side of 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).
  • 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.
  • 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.
  • Suite Hob configuration corresponds to its own bit pattern with its own address. There are so many addresses how there are possible configurations.
  • the memory (20) is equipped with a further memory, in particular connected to an EEPROM (21). This is with the address provided for the respective assignment writable.
  • EEPROM Electrically erasable read-only memory
  • 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 second can be used for the programming process Button (see line 24).
  • 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), specifically their 2nd circuit, on the relay (5) and thus the Cooking point (1) is switched when the block (19) Switch-on signal to the AND gate (14) is applied.
  • the address "1" is selected if the hob type is like 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.
  • the address "2" is selected when the hotplate (2) is the two-ring hob and its second circle from Relay (5) should be controlled.
  • 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.
  • 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.
  • 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.
  • 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 relay necessary, that 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 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 different types of hob guarantee.
