Definitions
- the invention is based on a hob with a plurality of heating elements and with at least one power electronics module according to the preamble of claim 1.
- EP 0 971 562 B1 discloses an induction hob with a plurality of heating elements, two power electronics modules for generating a heating current for operating the heating elements, and a switching arrangement for producing and disconnecting a connection between the power electronics module and the heating elements.
- the switching arrangement is mounted in a generic hob with the inverters that form the power electronics module on a circuit board.
- simpler cooktops are known in which the heating elements are permanently wired, each with a power electronics module without intervening switching arrangement.
- the invention is in particular the object of providing a hob with a flexible architecture.
- the invention relates to a hob, in particular an induction hob, with a plurality of heating elements, at least one power electronics module for generating a
- Heating current for operating the heating elements and with a switching arrangement for establishing and disconnecting a connection between the power electronics module and the heating elements is proposed.
- the switching arrangement is designed as an assembly separate from the power electronics module. This allows the same power electronics assembly to be used both in cooking panels that have hard-wired heaters to the power electronics assembly and in hobs that include circuitry for making and breaking the connection between the heater and the power electronics assembly.
- An adaptation of the switching arrangement and the power electronics module to different operating conditions can be done independently, so that, for example, the power electronics module for different countries with different household power networks can be chosen differently. Even when servicing a replacement of a single module can be made possible cost.
- the advantages of the invention are particularly evident in induction cooking fields in which the heating elements are inductors and in which the power electronics module comprises at least one inverter for generating the heating current.
- the power electronics module comprises at least two inverters. Increasing the number of inverters and / or inductors increases the complexity of the circuit arrangement, so that the provision of a separate module with increasing inductor number becomes more and more expedient.
- the switching arrangement comprises a plurality of capacitors, which are each assigned to a heating element designed as an inductor. Since the switching arrangement usually already comprises one output per inductor, the resonant capacitor, which complements the inductor to a resonant resonant circuit, can be very well integrated into the switching arrangement.
- the assembly of the switch assembly includes a pot detection circuit, it may be protected from interference from the power electronics assembly or inverters, and the outputs to the inductors may be used to transmit sensing pulses to the inductors.
- the assembly of the switching arrangement comprises a microcontroller for actuating switching elements of the switching arrangement. This allows a largely self-sufficient switching arrangement can be achieved, which can be controlled with a minimum control effort of a central control unit of the hob.
- the hob comprises temperature sensors which are attached to the heating elements designed as inductors, and a read-out circuit integrated in the assembly of the switching arrangement for reading out measured values of the temperature sensors.
- a read-out circuit integrated in the assembly of the switching arrangement for reading out measured values of the temperature sensors.
- the power electronics module and / or the assembly of the switching arrangement comprises at least one connector means for establishing a communication and / or power line connection between the power electronics module and the assembly of the switching arrangement.
- the power electronics module may include a rectifier, a filter circuit and an interface to a household power grid.
- FIG. 3 shows the power electronics module of Figure 1 in a detailed view
- FIG. 1 shows an induction hob with a plurality of heating elements arranged in a matrix.
- the heating elements are inductors 10, which are operated by two power electronics modules 24.
- the power electronics modules 24 generate a high-frequency heating current and are connected via a switching arrangement 14 with the inductors 10.
- the switching arrangement 14 serves to establish and disconnect the connection between the power electronics module 24 and the heating elements designed as inductors 10 and comprises a number of electromechanical relays 26 or semiconductor relays.
- a control unit 16 of the induction hob controls the operation of inverters 12 of the power electronics assembly 24 and actuates the switching assembly 14 such that the control unit 16 summarizes arranged in a vicinity of a bottom of a cookware 18 inductors 10 to flexibly definable heating zones 20.
- the combined to a heating zone 20 inductors 10 are operated by the control unit 16 for heating the cooking utensil element 18 in a coordinated manner.
- the combined to the heating zone 20 inductors 10 are operated in particular so that destructive interference between the inductors and a hum of the induction cooktop are avoided.
- the heating frequencies of the heating currents are matched to one another, preferably the inductors 10 of a heating zone 20 are operated at the same heating frequency, or a minimum distance of approximately 25 kHz between the heating frequencies is maintained, so that a resulting intermodulation frequency is outside of a heating frequency human audible frequency range.
- the number of inverters 12 in the power electronics assembly 24 of the induction cooktop is much smaller than the number of inductors 10.
- each of a total of four groups of inductors 10 is associated with an inverter 12.
- the elements of the switching arrangement 14 are mounted on a separate board 28 carrying a separate assembly 54 from the power electronics assembly 24.
- FIG. 2 shows an interconnection of the inverters 12 with the inductors 10 via the switching arrangement 14.
- the inductors 10 of a group are connected in parallel and the switching arrangement 14 comprises, for each inductor 10, a relay 26 which, in a first switching position, forms a conductive connection between the inverter 12 and the inductor 10 produces and interrupts this conductive connection in a second switching position.
- the control unit 16 can generate currents for activating electromagnets of the relays 26 via control lines and thus actuate the electromagnets of the relays 26 independently of one another in order to activate this inductor 10 by establishing the connection between the inverter 12 and the inductor 10.
- FIG. 3 shows one of the power electronics modules 24 from FIG. 1 in a more detailed representation.
- the power electronics module 24 includes two inverters 12 for generating the heating current.
- the inverters 12 are half-bridge inverters in the exemplary embodiment illustrated in FIG.
- a rectifier 30, a filter circuit 32 and an interface 34 to a household power network 36 are integrated into the power electronics module 24.

- the switching arrangement 14 has a multiplicity of output interfaces 38, which can be connected to one inductor 10 each.
- the inductors 10 can be controlled independently of each other in this way.
- a multiplicity of capacitors 40 are integrated into the switching arrangement 14, which are each arranged between a relay 26 and an output interface 38.
- the capacitors 40 are each associated with one of the inductors 10, and the capacitors 40 complete the respective inductor 10 to a series resonant circuit whose resonant frequency is in the range of the frequency of the heating current, which is of the order of 75kHz.
- the assembly 54 of the switching arrangement 14 further comprises a pot detection circuit 42, which can also be connected via the relay 26 to the inductors 10.
- the pot detection circuit 42 generates low-voltage measuring pulses, which generates an oscillation in one of the series resonant circuits formed by the inductors 10 and the capacitors 40. From an attenuation of this oscillation is closed to the presence of a cooking pot 18 and a degree of coverage between the saucepan 18 and the inductor 10 in question.

- a microcontroller 44 for actuating the switching elements or relays 26 of the switching arrangement 14 and a readout circuit 46 are integrated into the assembly 54 of the switching arrangement 14.
- the inductors 10 each carry in their centers a temperature sensor 48 shown in FIG. 1, the measured values of which are read out by the read-out circuit 46 and translated into a pulse-width-modulated or frequency-coded signal.
- the power electronics module 24 and the assembly 54 of the switching assembly 14 each comprise two complementary connector means 50, 52.
- the first connector means 50 is an interface for transmitting low-voltage control signals and serves to establish a communication connection between the power electronics module 24 and the assembly 54 of Switching arrangement 14.
- the second connector means 52 connects the inverters 12 to the inputs of Switching units 26 of the switching arrangement 14 and is designed to transmit the heating currents whose amplitude is of the order of 100V.
