The term "control unit" includes the concept of an electronic unit that


    preferably it is integrated, at least in part, in a control and / or regulator unit of the cooking appliance device, and which is preferably intended to direct and / or regulate at least one power supply unit of the appliance appliance cooking to supply power to the heating unit. Preferably, the control unit comprises a calculation unit and, in addition to the calculation unit, a storage unit with a control and / or regulation program stored therein, which is intended to be executed by the unit Calculation Particularly advantageously, the control unit can be provided to connect and disconnect the power supply unit so that it transmits to the heating unit a medium power, preset by the user, during a period of operation comprising several connection and / or disconnection processes. The heating unit may have at least one induction heating unit that is operable by a heating frequency unit of the cooking device. The term "heating frequency unit" includes the concept of an electrical unit, namely, a power supply unit, which generates an oscillating electrical signal, preferably with a frequency of at least 1 kHz, preferably 10 kHz. at least, advantageously, at least 20 kHz and, preferably, at most 100 kHz, for an induction heating unit. The heating frequency unit is intended to provide a maximum electrical power, requested by the induction heating unit, of at least 1,000 W, preferably, at least 2,000 W, advantageously, at least 3,000 W and, of Preferred way, at least 3,500 W. The heating frequency unit comprises at least one inverter, which preferably has at least two bidirectional unipolar switches, preferably connected in series, which are formed by a transistor and a diode connected in parallel and, particularly advantageously, at least in each case an attenuating capacity, connected in parallel to the two-way unipolar switches, which is formed by at least one capacitor. A voltage outlet of the heating frequency unit is disposed at a common contact point of two bidirectional unipolar switches. It is conceived that two heating frequency units are at least partially provided to simultaneously operate an induction heating unit. It is also conceived that a sensor unit of the cooking appliance device measures at least the voltage and / or the current in at least one heating unit, so that the instantaneous power in the heating unit can be advantageously determined. In addition, it is conceived that the control unit automatically directs the supply of


    energy of the heating unit by means of information from the sensor unit, in particular, by feedback.
    The term "operating state" of the control unit includes the concept of a state in which the control unit directs and / or regulates the power supply of at least one component of the cooking apparatus, in particular, a state in which that power is supplied to at least one heating unit, preferably continuously and / or with temporary interruptions. The power supply may be an electric power supply, preferably of direct current and / or alternating current. In at least one state of operation, alternate operation of at least two heating units may be provided, which may have intermediate time spans during which no heating unit is connected.
    The expression "in an aperiodic manner" includes the concept of the presence of a temporary aperiodicity, where the term "aperiodicity" includes the concept of irregular repetition, preferably at different time intervals, of a process, in particular, of a connection process of the control unit. Particularly advantageously, the two consecutive cycle durations during an aperiodic operation of at least one heating unit have at least essentially different duration. The term "at least essentially different duration" includes the concept of a minimum difference of the time duration of two time periods of at least 1%, preferably, of at least 3%, preferably, of at least 5% or, particularly preferably, of at least 10% of the largest time segment.
    The term "cyclically" includes the concept of the repetition of equal processes, in particular, of a succession of equal processes, preferably, a succession of equal connection states of the control unit, for example, a succession of processes of connection and disconnection of a heating unit, where the cycle duration of the cycles may have a different extension. A cycle may comprise, for example, all connection processes between a connection of a heating unit and a new connection of the same heating unit. The term "cycle duration" includes the concept of the finite duration of at least one cyclic process, for example, the time duration between a connection and a new connection of a heating unit. The term "partial cycle duration" includes the concept of a part of the cycle duration, for example, the time duration between a connection process and a disconnection process of the heating unit, where the partial cycle duration is of preferred way considerably shorter than the entire cycle duration. The


    "considerably shorter" term includes the concept of at least 1% shorter, preferably, at least 5% shorter, preferably, at least 10% shorter or, particularly preferably, of at minus 15% shorter.
    Through a corresponding embodiment, a cooking appliance device with better properties in terms of comfort, in particular, in terms of operating comfort and / or convenience of use can be advantageously achieved. Advantageously, through an aperiodic variation of the cycle time by means of the control unit, subjective noise pollution can be reduced and / or an objective noise reduction can be achieved compared with a periodic variation of the cycle time . In particular, the volume of noise produced regularly during operation can be advantageously reduced and / or the monotony of noise produced during operation can be advantageously avoided, in particular the noise caused, for example, by the bubbles of a cooking liquid that rise regularly and / or by the vibration of the cooking battery. In this way, a lower perceptibility of the noise can be advantageously achieved, since the user generally perceives as noticeably more annoying a uniform or repetitive noise such as, for example, a hum, a beep and / or a regular tapping, which irregular noise such as background noise or bubbling. In addition, an aperiodic variation of the cycle duration can be advantageously used as an information carrier. By way of example, an aperiodic cycle sequence could advantageously send digital information to a receiver that measured the cycle time, for example, a cooking battery and / or a household appliance. Thus, greater flexibility of the cooking appliance device is achieved. In addition, better cost efficiency can be advantageously achieved, since separate wireless transmitters, for example, bluetooth or WLAN transmitters, can be dispensed with for the transmission of information.
    In addition, it is proposed that the control unit be provided in at least one operating state to vary the cycle time randomly. A random variation of the cycle duration can occur after several cycles or, preferably, after each particular cycle. The cycle time can be determined randomly in the control unit by a random number generator. Advantageously, it can be provided that the control unit disregards determined cycle times through the generator of random numbers that essentially correspond to the previous cycle times. The term "correspond essentially" includes the concept that the difference between two consecutive cycle times is 10% maximum, preferably 5% maximum, more preferably 3% as


    maximum or, particularly preferably, 1% maximum of the longest cycle time. In this way, the repetition of two similar cycle times can be advantageously avoided. Likewise, it is conceived that the random number generator provides only values of an appropriate, determined range of values. Thanks to the random variation of the cycle time, a possible, uniform and / or monotonous noise can be advantageously avoided, in particular, the generation of a possible, uniform and / or monotonous noise.
    Likewise, it is proposed that the control unit be provided in at least one operating state to periodically repeat the cycle duration, where the expression "periodically repeat" the cycle duration includes the concept that the TN cycle duration of a N-th cycle essentially corresponds to the TN + n cycle duration of an N + n-th cycle. The term "essentially corresponds" includes the concept that the difference between the cycle times TN and TN + n amounts to a maximum of 10%, preferably, a maximum of 5%, more preferably, a maximum of 3% and, particularly preferably, at a maximum of 1% of the longest cycle time. "N" corresponds to a positive integer greater than 1, preferably, greater than 5, more preferably, greater than 10 and, particularly preferably, greater than 50, whereby too rapid repetition can be advantageously avoided. of the same cycle times. It is conceived that the control unit, in particular, the programming of the control unit, has a predefined sequence of cycle times and / or that allows the predefined sequence of cycle times. Thanks to the periodic repetition of the cycle duration, in particular, thanks to the predefined setting of a sequence of cycle durations, a possible, uniform and / or monotonous noise can be advantageously avoided, in particular, the generation of a possible noise , uniform and / or monotonous.
    Furthermore, it is proposed that the control unit be provided in at least one operating state to keep at least essentially constant the ratio of the partial cycle duration and the cycle duration. In this way, it can be advantageously achieved that a relative percentage of all the partial cycle durations added to a total operating time essentially corresponds to a percentage of a partial cycle duration of the corresponding cycle duration, where the term “Total operating time” includes the concept of the sum of all cycle times during an operation in an operating state. The term "essentially constant" includes the concept that the quotient comprises a relative deviation of a maximum of 10% for different cycle times, preferably a maximum of 5%,


    more preferably, a maximum of 3% and, particularly preferably, a maximum of 1% of the average value of all the ratios that occur during the total operating time. In particular, it is conceived that, in the operating state in which the ratio of the partial cycle duration and the cycle duration is at least essentially constant, the control unit supplies a constant power to a heating unit. In this way, an average supply of power to a heating unit, in particular, to a firing battery, constant, in particular, without fluctuations, is advantageously possible during a temporary space comprising several cycles. In addition, it is conceived that the partial cycle time and / or the average power of the heating unit are calculated and / or set by the microcontroller of the control unit.
    If the control unit is provided in at least one operating state to maintain the difference between the cycle time and the partial cycle duration preferably around 600 ms maximum, more preferably, around 500 ms maximum , more preferably, around 400 ms maximum and, particularly preferably, around 300 ms maximum, the bottleneck effect can then be advantageously avoided, where the "bottleneck effect" includes the concept of the temporary interruption of a cooking process, in particular, the temporary interruption of the formation of bubbles during a cooking process, which occurs when a cooking battery with low thermal inertia is used, for example, light-walled thin-walled pots With good thermal conductivity. In this way, greater comfort of use is advantageously achieved. Furthermore, it is conceived that the difference between the cycle time and the partial cycle duration is greater than 5 ms, preferably, greater than 20 ms, more preferably, greater than 50 ms and, particularly preferably, greater than 100 ms.
    It is also proposed that the control unit be provided in at least one operating state to supply power to at least one other heating unit for another partial cycle duration of the cycle duration. In this way, the flexibility of the cooking appliance device can be advantageously increased. In addition, it can be advantageously achieved that costs are saved, since power can be supplied to several heating units by means of a control unit. It is conceived that the control unit supplies power to at least a third and / or other additional heating units for a third and / or other additional partial cycle times.


    In addition, it is proposed that the other partial cycle duration and the partial cycle duration do not overlap temporarily. In this way, a simple connection of the power supply of the heating units can be advantageously achieved, since, for example, only by a single switch of the cooking appliance device can it be connected in either direction between the two units heating Thus, the complexity of a connection arrangement can be advantageously reduced. In addition, during operation without overlapping of two heating units, the simultaneous operation of two heating units can be advantageously prevented, which can cause an audible difference frequency if both heating units are induction heating units. The term "difference frequency" includes the concept of the frequency that corresponds to the frequency difference of two heating frequency units in at least one operating state during simultaneous operation. The other partial cycle durations and partial cycle durations do not overlap temporarily if, in at least one operating state, the difference frequency of two heating units corresponds to the maximum 17 kHz value.
    It is also proposed that the control unit be provided in at least one operating state to keep at least essentially constant the ratio of the other partial cycle duration and the cycle duration. In this way, it can be advantageously achieved that a relative percentage of the partial cycle durations added from a total operating time essentially corresponds to a percentage of a partial cycle duration of the corresponding cycle duration. In particular, it is conceived that, in the operating state in which the ratio of the partial cycle duration and the cycle duration is at least essentially constant, the control unit supplies a constant power to a heating unit. In this way, an average power supply to a constant heating unit, in particular, without fluctuations, is advantageously possible during a temporary space comprising several cycles.
    If the control unit is provided in at least one operating state to maintain the difference between the cycle time and the other partial cycle duration preferably around 600 ms maximum, more preferably, around 500 ms as maximum, more preferably, around 400 ms maximum and, particularly preferably, around 300 ms maximum, the bottleneck effect can then be advantageously avoided. In this way, greater comfort of use is advantageously achieved. In addition, it is conceived that the difference between the cycle time and


    the other partial cycle duration is greater than 100 ms, preferably, greater than 50 ms, more preferably, greater than 20 ms and, particularly preferably, greater than 5 ms.
    Likewise, it is proposed that the control unit be provided in at least one operating state to transmit information, in particular, digitized, by means of the variable cycle duration. By way of example, an aperiodic cycle sequence could advantageously send digital information to a receiver that measured the cycle time, for example, a cooking battery and / or a domestic appliance, in particular an induction-driven domestic appliance, by For example, a wireless mixer. Thus, greater flexibility of the cooking appliance device is achieved. In addition, better cost efficiency can be advantageously achieved, since separate wireless transmitters, for example, bluetooth or WLAN transmitters, can be dispensed with for the transmission of information.
    In addition, it is proposed that the heating unit be made as an induction heating unit. Thus, in comparison with a resistance heating unit, a reduced reaction time can be advantageously achieved during which a cooking product is quickly heated. Thus, the cooking processes can be directed better than in a kitchen with resistance heating units. In addition, it is conceived that all other heating units of the cooking appliance device are also made as induction heating units.
    Likewise, a procedure is proposed for putting into operation a cooking device, in particular, an induction cooking device, in which at least one heating unit is cyclically actuated in an aperiodic manner with a duration variable cycle, and the heating unit is supplied with energy during a partial cycle duration of the cycle duration. In this way, a cooking appliance device with better properties in terms of comfort, in particular, in terms of operating comfort and / or convenience of use can be advantageously achieved. Advantageously, through an aperiodic variation of the cycle time by means of the control unit, a noise reduction can be achieved in comparison with a periodic variation of the cycle time. In particular, the volume of noise that occurs regularly during operation can be advantageously reduced and / or the monotony of noise produced during operation can be advantageously avoided, in particular the noise caused by


    for example, by the bubbles of a cooking liquid that rise regularly and / or by the vibration of the cooking battery. In this way, a lower perceptibility of the noise can be advantageously achieved, since the user generally perceives as noticeably more annoying a uniform or repetitive noise such as, for example, a hum or a beep, than an irregular noise such as example, a background noise or a bubbling. In addition, an aperiodic variation of the cycle duration can be advantageously used as an information carrier. By way of example, an aperiodic cycle sequence could advantageously send digital information to a receiver that measured the cycle time, for example, a cooking battery and / or a household appliance. Thus, greater flexibility of the cooking appliance device is achieved. In addition, better cost efficiency can be advantageously achieved, since separate wireless transmitters, for example, bluetooth or WLAN transmitters, can be dispensed with for the transmission of information.

    Figure 1 shows a cooking appliance with a cooking appliance device, in schematic top view. In the present case, the cooking apparatus is made as a cooking field, in particular, as an induction cooking field.
    The cooking device has a cooking field plate 60, which defines four cooking zones 58, 62, 64, 66. In addition, the cooking device has four heating units 12, 14, 24, 28 At least one heating unit 12, 14, 24, 28 is arranged below a respective cooking zone 58, 62, 64, 66. It is conceived that under a cooking zone 58 more than one heating unit 12, 14, 24, 28 is arranged. Each of the heating units 12, 14, 24, 28 comprises an induction heating unit 16, 18 , 26, 30. The cooking appliance device may also have a number of cooking zones 58, 62, 64, 66 and / or heating units 12, 14, 24, 28 and / or induction heating units 16, 18, 26, 30 other than four.
    Two cooking batteries 20, 22 are resting on the surface of the cooking field plate 60. The cooking battery 22 is in the area of the cooking zone 62. The cooking battery 20 is in the area of the cooking zone cooking 66. The two heating units 12, 14 are electrically connected to a common power supply unit 56 of the cooking device (see Figure 2), with a common filter 34 of the cooking device, and with a common rectifier 40 of the cooking appliance device. The two heating units 24, 28 are electrically connected with another common power supply unit 54 of the cooking appliance device, with another common filter 52 of the cooking appliance device, and with another common rectifier 42 of the cooking appliance device cooking (see figure 2).
    The cooking device device has a control panel 68, with a control field 32. The control field 32 has at least one control means 70, which is intended to activate at least one operating state of the cooking device and / or to vary at least one operating parameter of the cooking apparatus. The control means 70 is made as a rotary knob. Preferably, the control means 70 could be made as a push switch and / or as a pressure switch and / or as


    rocker switch and / or as a slide switch and / or as another type of switch that is appropriate to the person skilled in the art.
    Also, the cooking device device has a control unit 10. The control unit 10 has a transmission element 72, which transmits at least one adjustment of the command field 32 to the control unit 10 (see Figure 1 ), and is intended to activate at least one heating unit 12, 14, 24, 28.
    Figure 2 shows a wiring diagram of a part of the cooking appliance device. The cooking appliance device has at least one heating frequency unit 44, 46, 48, 50. The control unit 10 supplies the heating units 12, 14, 24, 28 with energy in the form of a high frequency alternating current. by means of the heating frequency units 44, 46, 48, 50. Each of the heating frequency units 44, 46, 48, 50 comprises an inverter. The control unit 10 directs the connection position of the switches 36, 38, 74, 76, 78, 80 of the cooking device.
    The switch 36 is intended to separate the heating units 12, 14 from the power supply unit 56 or to connect the heating units 12, 14 with the power supply unit 56. The switches 78, 80 are intended to connect and disconnecting the heating units 12, 14. The switch 38 is intended to separate the heating units 24, 28 from the power supply unit 54 or to connect the heating units 24, 28 with the power supply unit 54 The switches 74, 76 are intended to connect and disconnect the heating units 24, 28.
    Figure 3 shows the temporal evolution of the current of two heating units 12, 14, 24, 28. On the ordinate 84 is drawn the current I, and on the abscissa 86 the time t is plotted. The abscissa 86 comprises two time axes 92, 94. Along the time axis 92, the temporal evolution 88 of the current I is drawn, which flows through the heating unit 12, 14, 24, 28. A along the time axis 94 the temporal evolution 90 of the current I is represented, which flows through another heating unit 12, 14, 24, 28, connected with the same current supply unit 54. In both Temporary evolutions 88, 90 show only in each case schematically an upper envelope and a lower envelope of the actual evolution of the current, where a "higher envelope of the actual evolution of the current" includes the concept of a line that joins all the maximums of the real evolution of the current, and a “lower envelope of the real evolution of the current” includes the concept of a line that


    one all the minimums of the actual evolution of the current. The amount of enclosure bulges shown in Figure 3 is to be understood by way of example only, and may differ considerably in actual operation.
    A total operating time T of an operation of the cooking appliance device is divided into an amount N of consecutive TN cycle times, which in turn comprises a number n of partial cycle times TNn. The index n numbers the partial durations of the TNn cycle of a TN cycle duration.
    In Figure 3, three different cycle times T1, T2, TN are shown by way of example, each with a first partial cycle duration T11, T21, TN1 and a second partial cycle duration T12, T22, TN2. The control unit 10 is intended to drive at least one heating unit 12, 14, 24 28 cyclically in an aperiodic manner with a variable TN cycle time, and to supply power to the heating unit 12, 14, 24, 28 during at least the partial cycle duration TN1, TN2 of the TN cycle duration.
    In the case present in Figure 3, during the first partial cycle duration T11, T21, TN1, the control unit 10 supplies power to the heating unit 12, 14, 24, 28 and, during the second partial cycle duration T12, T22, TN2, the control unit 10 supplies power to the other heating unit 12, 14, 24, 28. The partial cycle times TN1, TN2 are maintained by the control unit 10 without overlaps. It is conceived that the cycle duration TN is subdivided into a number n of partial durations of the TNn cycle other than two, where, by means of the control unit 10, they also do not overlap each other or with the partial cycle durations TN1, TN2 all other partial durations of the TNn cycle.
    The control unit 10 is intended to vary the cycle time TN randomly. In Figure 3, three different cycle times T1, T2 and TN are shown. In the case of a random variation, all other TN cycle durations that are between a maximum cycle duration TN, max and a minimum cycle duration TN, min are conceived (see Figure 4).
    The ratio of the partial cycle durations T11, T21, TN1 and the corresponding cycle durations T1, T2, TN shown in Figure 3 is kept constant by the control unit 10. In the present case, with two partial durations of TN1 and TN2 cycle for each TN cycle duration means that also the ratio of the partial cycle durations T12, T22, TN2 and the corresponding cycle durations T1, T2, TN is kept constant


    by the control unit 10. It is conceived that a TN cycle duration contains other partial TNn cycle durations, with a constant quotient with the TN cycle duration.
    The control unit 10 is provided in at least one operating state to maintain the difference between the cycle duration TN and the partial cycle duration TN1 or the partial cycle duration TN2 around 600 ms maximum. In the case present in Figure 3 with two partial cycle times TN1, TN2 for each cycle duration TN, the difference between the cycle duration TN and the partial cycle duration TN1 corresponds to the partial cycle duration TN2, since the inverse It is conceived that the difference comprises several of other partial durations of the TNn cycle.
    In figures 4a to 4c, in each case an example time sequence of consecutive N cycles with corresponding TN cycle durations is shown. On the ordinate 98, the TN cycle time is plotted in each case, and a discrete succession of N cycles is plotted on the abscissa 96 in each case. The two discontinuous horizontal lines indicate a maximum cycle time TN, max and a minimum cycle time TN, min.
    In the exemplary embodiment shown in Figure 4a, the TN cycle duration sequence shows a pyramid evolution profile 100 with a gradual rise in the TN cycle durations from a value close to the minimum TN cycle time, min up to value close to the maximum cycle time TN, max. In the present case of Figure 4a, the control unit 10 repeats the cycle time TN periodically, for example, the cycle time T1 corresponds to the cycle time T13.
    The control unit 10 is provided in at least one operating state to transmit information via the variable TN cycle time. By way of example, the periodic, pyramidal repetition of Figure 4a can be interpreted by a receiver, which can be performed as a cooking battery 20, 22, as specific information that causes a reaction in the receiver, for example, an acoustic signal .
    In the exemplary embodiment shown in Figure 4b, the sequence of cycle times TN shows a random evolution profile 102, in which the cycle duration TN is randomly modified in each cycle N. In the example of embodiment shown in Figure 4c, the sequence of TN cycle durations shows a random evolution profile 104, in which the TN cycle duration is randomly modified in each case after five cycles of the same duration.


    In a procedure for putting into operation a cooking appliance device, at least one heating unit 12, 14, 24, 28 is cyclically actuated in an aperiodic manner with a variable TN cycle time, and to the heating unit 12, 14, 24, 28 power is supplied to it during a partial cycle duration TN1 of the TN cycle duration. Here, the power supply to the heating unit 12, 14, 24, 28 is connected and disconnected once after another by the control unit 10, where the consecutive TN cycle times extending in each case, for example, from a connection process to the next connection process, they have a different duration.
