In particular, the present The type of heating can be selected by an operator and / or by the control unit. A type of heating that can be selected by an operator could, for example, be directly and / or indirectly selectable by the operator.

The phrase that only a "heating output of a maximum of one heating output limit value" is available for heating a cookware with at least one type of heating is intended to mean in particular that only one heating output is available for heating the cookware with the present heating type, which has and / or can assume a value less than or equal to the heating power limit value.

A “heating output limit value” is to be understood in particular as a value which indicates a maximum heating output available in the operating state. The heating output limit value could, for example, be predefined and / or, in particular fixed and / or variable, specified. For example, the heating power limit value could be specified and / or predefined by at least one mains voltage phase and / or at least one intelligent power network. As an alternative or in addition, the heating output limit value could be specified, for example, by at least one operator, for example by setting it via the operator interface.

A "heat output selectable in at least one further operating state for the present type of heating" is to be understood as meaning, in particular, a heating output which can be selected for the present type of heating in the further operating state in which in particular an available energy and / or heating output is sufficient . In the further operating state, in particular a potential of the present type of heating can be fully exploited and / or a maximum heating power provided for the present type of heating can be selected. In particular, the cookware could be heated in the further operating state with a maximum heating power provided for the present type of heating with the present type of heating. The further operating state is in particular free of restrictions for the present type of heating. In particular, the present type of heating is free of restrictions in the further operating state. In particular, an adaptation of the operator interface can be dispensed with in the further operating state.

An “adaptation” of the operator interface is to be understood as meaning, in particular, a change in at least one property of the operator interface. The property of the operator interface could, for example, be an output and / or an input selection and / or a selection option. For example, an arrangement and / or an intensity and / or a color and / or a size of an output of the operator interface could be adapted and / or changed. Alternatively or additionally, for example, an input selection and / or a selection option of the operator interface could be adapted and / or changed. For example, a selection option of the user interface could be adapted and / or changed by changing a number of selectable heating types and / or by changing a number of heating outputs, which are available in particular for the present heating type in the further operating state.

An adaptation of the operator interface "depending on the type of heating present" is to be understood in particular as meaning that the operator interface is adapted in different ways for different types of heating present and / or that the operator interface is adapted in different ways for one, in particular, one type of heating present Way is adjusted.

“Provided” is to be understood in particular as specifically programmed, designed and / or equipped. The fact that an object is provided for a specific function should be understood in particular to mean that the object fulfills and / or executes this specific function in at least one application and / or operating state.

For example, the method could be designed as a method for manufacturing the hob and in particular be provided for implementation by at least one person. The method is particularly advantageously designed as a method for operating the hob and is provided, in particular, for implementation by the control unit. In particular, in the method, the user interface to prevent the heating output limit value from being exceeded is actively adapted, depending on the type of heating present, by at least one control unit of the hob, which is equipped to carry out the type of heating and at least one other type of heating. In particular, this can result in a high Flexibility and / or little effort can be achieved in the production of the hob.

In order to prevent the heating output limit value from being exceeded, the operator interface could be actively adapted by the control unit in at least one initialization step to initialize the hob as a function of the type of heating present. Preferably, the user interface to prevent the heating power limit value from being exceeded in at least one operation of the hob, which in particular is arranged and / or takes place after at least one initialization step for an initialization of the hob, is active and / or variable by the control unit depending on the current one Adjusted heating type. In particular, this enables particularly high operating convenience. In particular, a maximum possible selection of types of heating can be made available to an operator in a company, which can be adapted in particular as a function of the type of heating present.

It is also proposed that the present type of heating be selected via the operator interface, in particular at a time prior to the adaptation of the operator interface as a function of the present type of heating by the control unit. The type of heating at hand could, for example, be selected indirectly and / or directly via the operator interface. For example, an operator could activate at least one control unit via the operator interface, which in particular could automatically select the type of heating present. The operator interface is advantageously adapted as a function of at least one type of heating selected via the operator interface, in particular directly, advantageously by the operator, in particular by the control unit. As a result, a flexible and / or comfortable configuration can be achieved, in particular, whereby a high level of satisfaction for an operator can be achieved.

It is further proposed that the operator interface is adapted to prevent the heating power limit value from being exceeded in at least one initialization step for initializing the hob. This makes it possible in particular to keep a small amount of stock since, in particular, only a single control unit has to be programmed and / or equipped for different hobs, since the Control unit in the initialization step in particular to the hob in which the control unit is installed.

For example, the operator interface could be adapted differently to prevent the heating output limit value from being exceeded, in particular exclusively as a function of the type of heating present. The operator interface is preferably adapted differently to prevent the heating output limit value from being exceeded, in particular in addition to the dependency on the type of heating present, depending on at least one cooking utensil configuration. A "cooking utensil configuration" is to be understood in particular as a property which characterizes cooking utensils located in particular on the hob, in particular for the purpose of being heated by the hob. The cooking utensil configuration could, for example, be an arrangement of cooking utensils on the hob, in particular absolutely and / or relative to at least one hob edge and / or relative to one another. Alternatively or additionally, the cooking utensil configuration could in particular be a property of a cooking utensil itself, such as, for example, a size and / or a shape and / or a material of the cooking utensil. The cooking utensil configuration could, for example, be an order in which cooking utensils are and / or have been arranged on the hob. As an alternative or in addition, the cooking utensil configuration could in particular be a spatial proximity of at least two cooking utensils set up on the hob. In this way, in particular, a high degree of flexibility can be achieved and / or a variable response to a given cooking utensil configuration can be achieved.

In addition, it is proposed that at least one output is adapted via the operator interface in order to prevent the heating output limit value from being exceeded. In particular, at least one output of a heating output parameter could be adapted in order to prevent the heating output limit value from being exceeded. When adapting the heating output parameter, in particular an intensity with which the heating output parameter is output could be adapted, in particular reduced. As an alternative or in addition, when adapting the heating output parameter, in particular an output of the heating output parameter could be dispensed with. In order to prevent the heating output limit value from being exceeded, in particular at least one output of information to an operator could be carried out. The information to the operator could for example be in the form of a marking and / or of a symbol, for example by means of an exclamation mark and / or by means of a change in intensity and / or by means of a color change and / or a warning signal. The color change could, for example, be graying out and / or a colored background. Alternatively or additionally, the information could be output to the operator, for example, in the form of a message, in particular a text and / or a voice message, which could in particular contain an explanation of why and / or that an adaptation of the operator interface is being made and / or has been made. In particular, this enables a high level of operating comfort and / or a high level of satisfaction for an operator, since the operator can in particular be made aware of at least one adjustment and / or of at least one restriction.

It is also proposed that at least one input selection of the operator interface is adapted to prevent the heating output limit value from being exceeded. In particular, in order to prevent the heating output limit value from being exceeded in the operating state, in particular by the control unit, a maximum demandable power consumption of the present heating type could be limited for the present type of heating. For example, a heating output of a specific value could be selected and / or provided for the present type of heating in the further operating state. In the operating state, in particular by the control unit, a maximum demandable power consumption of the present type of heating could be limited to an adapted value, which could in particular be smaller than the maximum demandable certain value in the further operating state. Alternatively or additionally, in particular by the control unit, a selection of at least one type of heating, in particular the present type of heating, which an operator would like to select especially for the cooking utensil, could be prevented in the operating state, in particular in the course of setting up at least one cooking utensil. In particular, at least one type of heating could be activated and / or selectable, in particular exclusively in the case of an available heating power which is greater than or equal to a heating power that can be selected in the further operating state for the present heating type. Activation and / or selection of the at least one type of heating could be excluded in particular in the operating state, in particular by the control unit and advantageously by adapting the operator interface. In particular, this can result in a high Transparency and / or a high level of information can be achieved. In particular, anger and / or astonishment of an operator about inadequate and / or non-existent cooking results can be prevented.

For example, irrespective of the heating outputs provided for a given type of heating, an available heating output could be used to heat the cooking utensils that have been set up, whereby in particular a change to a maximum heating output intended for the present type of heating could be excluded. Preferably, in particular by the control unit and advantageously by adapting the operator interface, at least one heating power component is reserved for at least one type of heating. In particular, the heating output component corresponds to the heating output that is necessary to heat at least one cookware with a maximum heating output provided for the at least one heating type, whereby the at least one heating type can in particular be fully utilized and / or used without restrictions. In the case of at least two set up cooking utensils, to which in particular different types of heating could be assigned, for example at least one of the heating types could be prioritized and / or preferred, in particular by reserving at least one heating power component for the particularly prioritized and / or preferred at least one heating type. In this way, in particular, optimal cooking results can be ensured, since in particular an existing type of heating can be fully exhausted and / or an adaptation and / or restriction of at least one existing type of heating can be avoided.

A high degree of flexibility can in particular be achieved by a hob produced using the method. For example, the hob could be manufactured using the method only. Alternatively, the hob could be produced using the method and in particular additionally using at least one further method.

Flexibility can in particular be increased further by a hob with at least one control unit, which is provided for carrying out the method. In particular, the control unit could carry out the method in one operation and / or in at least one initialization step for initializing the hob. The method is not intended to be restricted to the application and embodiment described above. In particular, the method can have a number of individual elements, components and units that differs from a number of individual elements, components and units mentioned herein in order to fulfill a mode of operation described herein.

Fig. 1 shows a hob 10a, which is designed as an induction hob. The hob 10a is provided for setting up cooking utensils 14a. In one operation, the hob 10a is provided for heating cooking utensils 14a, in particular for inductive heating of cooking utensils 14a.

The hob 10a has a mounting plate 18a. In the present exemplary embodiment, the mounting plate 18a is designed as a hob plate. In an assembled state, the mounting plate 18a forms part of a hob outer housing, in particular a hob outer housing, in particular of the hob 10a. The mounting plate 18a is provided for putting up cooking utensils 14a.

The hob 10a has a large number of heating units for heating cooking utensils 14a (not shown). In the present exemplary embodiment, the heating units are arranged in the form of a matrix. The heating units are arranged in an installation position below the mounting plate 18a. The heating units are provided to heat cooking utensils 14a placed on the mounting plate 18a above the heating units. In the present exemplary embodiment, the heating units are designed as induction heating units.

The hob 10a has a user interface 12a for inputting and / or selecting operating parameters, for example a heating power and / or a heating power density and / or a heating zone. The operator interface 12a is provided for outputting a value of an operating parameter to an operator. The operator interface 12a is provided for outputting information to an operator.

The hob 10a has a control unit 16a. The control unit 16a is provided to carry out actions and / or to change settings as a function of the operating parameters entered by means of the operator interface 12a. The control unit 16a regulates an energy supply to the heating units in a heating operating state.

The control unit 16a is provided to carry out a method for the hob 10a. In the present exemplary embodiment, the control unit 16a executes the method for the hob 10a in one operation. In the present exemplary embodiment, the method for the hob 10a is designed as a method for operating the hob 10a.

The control unit 16a has a memory unit 20a. Several types of heating for cookware 14a are stored in the memory unit 20a. A type of heating is stored in the memory unit, which is referred to as "normal mode" (NM). A type of heating is stored in the memory unit, which is referred to as "Sensor Function" (SF). A type of heating is stored in the memory unit, which is called "Long Move "(LM). In the memory unit, a type of heating is stored, which is referred to as" Power Move "(PM). In the memory unit, a type of heating is stored, which is referred to as" Temperature Move "(TM) A type of heating is stored in the memory unit, which is referred to as "Free Control" (FC).

The control unit 16a is equipped to carry out the types of heating, specifically in particular a present type of heating and at least one further type of heating. A program for carrying out the heating types stored, in particular in the memory unit 20a, is stored in the memory unit 20a.

The hob 10a prevents the heating power limit value from being exceeded in an operating state, in particular by means of the control unit 16a. In the operating state, only a heating output of at most one heating output limit value is available for heating a cookware with a present heating type, which is lower than a heating output that can be selected in a further operating state for the present heating type.

In the following, "the operating state" is understood to mean that operating state in which only a heating power of at most one heating power limit value is available for heating a cookware with the present type of heating, which is less than a heating power that can be selected in the further operating state for the present heating type.

In the following, “the further operating state” is understood to mean an operating state in which sufficient energy and / or heating power is available and in particular the heating types stored in memory unit 20a can be carried out, in particular over an entire heating output range provided for the respective heating type.

In the present exemplary embodiment, the hob 10a prevents the heating output limit value from being exceeded by adapting the operator interface 12a as a function of the type of heating present. During operation, the control unit 12a adapts the operator interface 12a to prevent the heating output limit value from being exceeded as a function of the type of heating present. In the method, the exceeding of the heating output limit value is prevented by adapting the operator interface 12a as a function of the type of heating present.

In the method for preventing the heating output limit value from being exceeded, the operator interface 12a is actively adapted by the control unit 16a of the hob 10a as a function of the type of heating present. In the present exemplary embodiment, the control unit 16a is equipped to carry out the present type of heating and several other types of heating.

In the method in the present exemplary embodiment, the operator interface 12a is actively adapted by the control unit 16a to prevent the heating power limit value from being exceeded when the hob 10a is in operation, depending on the type of heating present. Before the operator interface 12a is adapted by the control unit 16a, the type of heating present is selected via the operator interface 12a. The operator interface 12a is provided for a selection of at least one type of heating from the types of heating stored in the memory unit 20a.

In the following, the Figures 1 to 19 different ways of adapting the operator interface 12a are shown and / or described. The types of heating and / or cooking utensil configurations selected here are only selected as examples and without restricting the generality. In order to achieve a high level of transparency and ease of understanding, the following is based on heating outputs in the form of levels, which can assume values from 0 to 9. A value of 0 corresponds to a deactivation and a value of 9 to a maximum heating output that can be selected in the further operating state.

In particular, a value of 9 of the heating output levels corresponds to 100% of the maximum heating output that can be selected in the further operating state. A value of 0 for the heating output levels corresponds to 0% of the maximum heating output that can be selected in the further operating state. A value of 5 of the heating output levels corresponds to 50% of the maximum heating output that can be selected in the further operating state. Further intermediate stages can be calculated in a simple manner and are therefore not described further.

A cookware 14a that has already been set up and heated is marked below with crossed hatching. A newly installed cooking utensil 14a, which is provided in particular for heating with the present type of heating, is identified below with parallel hatching.

For example, a cookware 14a is set up on the hob 10a. The control unit 16a heats the cookware 14a with one type of heating (cf. Fig. 1 ). In the present exemplary embodiment, it is assumed, without loss of generality, that the control unit 16a heats the cookware 14a with the type of heating referred to as “sensor function” (SF). Because of this, only a heating output of at most one heating output limit value is available for a further heating type, which is smaller than a heating output that can be selected in the further operating state for the present heating type.

In the operating state, a cookware 14a is placed on the hob 10a. By means of the user interface 12a, a type of heating is selected for the particular newly set up cooking utensil 14a. For example, the type of heating referred to as "normal mode" (NM) is selected for the cookware 14a that has been set up in particular. For the type of heating referred to as "normal mode" (NM), only a heating output with a value of 5, for example, is available. The heating output limit value for the type of heating referred to as “normal mode” (NM) is 5, for example.

When the heating output limit value is prevented from being exceeded, an output via the operator interface 12a is adapted, in particular by the control unit 16a. The control unit 16a outputs information 22a to an operator via the operator interface 12a. By means of the information 22a, the control unit 16a indicates to an operator that the heating output limit value is insufficient for heating the cooking utensils 14a with a heating output that can be selected in the further operating state for the present type of heating.

In order to prevent the heating output limit value from being exceeded, an input selection of the operator interface 12a is adapted, in particular by the control unit 16a. The control unit 16a restricts the input selection of the operator interface 12a, specifically in that the control unit 16a fades out heating outputs which would exceed the heating output limit value. In the present example, heating outputs are invisible to an operator in a restricted area 24a of an input selection. Alternatively, heating outputs could be highlighted in a restricted area 24a of an input selection, for example grayed out and / or highlighted in gray, whereby the heating outputs of the input selection arranged in the restricted area 24a are marked as being not selectable for an operator.

With an in Fig. 2 In the example shown, for example, in particular in addition to an already set up cooking utensil 14a, a cooking utensil 14a is set up at a first set-up position 26a. By means of the user interface 12a, a type of heating is selected for the particular newly set up cooking utensil 14a. For example, the type of heating referred to as "Long Move" (LM) is selected for the cookware 14a that has been set up in particular. At the first set-up position 26a, for example, a heating power with a value of 5 is selected for the cookware 14a that has been set up in particular.

In the “Long Move” (LM) type of heating, the cooking utensil 14a is moved from the first set-up position 26a to a second set-up position 28a, which is in particular in a vicinity of the already set-up cooking utensil 14a. At the second installation position 28a, only a heating output with a value of 1.5 is available. In order to prevent the heating output limit value from being exceeded, the control unit 16a adapts an input selection of the operator interface 12a as a function of the type of heating present.

With an in Fig. 3 For example, in addition to a set up cooking utensil 14a, a cooking utensil 14a is set up on the hob 10a at a set-up position in a cooking surface area for which the type of heating referred to as "Power Move" (PM) is selected. Alternatively, for the cooking surface area in which the cooking utensil 14a is set up, the type of heating referred to as "Temperature Move" (TM) could be selected, for example.

At the set-up position of the, in particular newly set-up, cooking utensils 14a, only a heating output of a heating output limit value is available for the heating type referred to as "Power Move" (PM), which is lower than a heating output that can be selected in the further operating state for the present heating type. The control unit 16a adapts an output via the operator interface 12a in the operating state when the heating power limit value is prevented from being exceeded. In the operating state, the control unit 16a outputs information 22a via the operator interface 12a, in particular in the form of a warning signal. By means of information 22a identifies the control unit 16a in the operating state that a heating power provided for the set-up position of the cooking utensils 14a is greater than a heating power limit value, which is why heating of the cooking utensils 14a at the set-up position is restricted and / or excluded.

In a further example (not shown), for example, in particular in addition to an already set up cooking utensil 14a, a cooking utensil 14a is set up at a set-up position. By means of the operator interface 12a, for example, the type of heating referred to as “sensor function” (SF) is selected for the, in particular, newly set up cooking utensil 14a. For heating with the heating type referred to as "Sensor Function" (SF), only a heating output of a heating output limit value is available, which is smaller than a heating output that can be selected in the further operating state for the present heating type. In the operating state when the heating power limit value is prevented from being exceeded, the control unit 16a adapts an output via the operator interface 12a, specifically in a manner analogous to that in FIG Fig. 3 example shown.

In the following, without loss of generality, the Figures 4 to 17 the type of heating known as "Free Control" (FC) is described. It is assumed in each case from the operating state and thus in particular that for a particularly newly installed cooking utensil 14a, only a heating output of a heating output limit value is available, which is lower than a heating output that can be selected in the further operating state for the present type of heating.

The control unit 16a adapts an input selection of the operator interface 12a in the operating state to prevent the heating output limit value from being exceeded. In the operating state, the control unit 16a highlights an input selection in a restricted area 24a. In Fig. 4 In the operating state, the control unit 16a highlights an input selection by graying out the input selection arranged in the restricted area 24a. In Fig. 5 In the operating state, the control unit 16a hides an input selection arranged in the restricted area 24a. In an in Fig. 6 In the illustrated example, the control unit 16a outputs information 22a in the operating state via the operator interface 12a, in particular in the form of a warning signal. The control unit 16a identifies by means of the information 22a in the operating state that heating of the cookware 14a with the present type of heating is restricted and / or excluded.

In order to prevent the heating output limit value from being exceeded, the control unit 16a adapts the operator interface 12a in the operating state differently depending on a cooking utensil configuration (cf. Figures 7 and 8 ). In the operating state, the control unit 16a adapts the operator interface 12a differently depending on a sequence in which cooking utensils 14a are set up. For example, in the operating state, a cooking utensil 14a is set up in the vicinity of an already set up, with the "Free Control" (FC) heating type heated cooking utensil 14a, for which the heating type, for example, the "Normal Mode" (NM) is then selected ( see. Fig. 7 ). In the process, a heating power component is reserved for one type of heating. In the example shown, a heating output component is reserved for the type of heating known as "Free Control" (FC). For the cookware 14a that has been set up in particular, only a heating output of a heating output limit value is available, which is lower than a heating output that can be selected in the further operating state for the present type of heating. In the operating state, the control unit 16a restricts an input selection of the operator interface 12a for the, in particular, newly set up cooking utensil 14a. In the operating state, the control unit 16a outputs information 22a, in particular about the restriction, in the form of a marking to an operator. In this example, the marker is an exclamation point.

For example, the too Fig. 7 The cooking utensils 14a described are set up in inverted order, the control unit 16a adapts the operator interface 12a differently (cf. Fig. 8 ). In the operating state, the control unit 16a outputs information 22a, in particular that the type of heating present cannot be selected, to an operator.

Especially as an alternative to the in Figures 7 and 8 illustrated example, the control unit 16a in the operating state could adapt the operator interface 12a differently regardless of a sequence in which cooking utensils 14a are set up (cf. Figures 9 and 10 ). In particular, analogous to the in Fig. 7 Cooking utensil configuration shown, for example, an already set up cooking utensil 14a is heated with a type of heating known as "Free Control" (FC). For the already set up, with the "Free Control" (FC) designated type of heating heated cooking utensils 14a, sufficient energy and / or heating power is available, which is why this cooking utensil 14a can be heated without restriction. A cooking utensil 14a is set up in a vicinity of the already set up cooking utensil 14a, which is heated with the "Free Control" (FC) heating type, for which the heating type designated as "Normal Mode" (NM), for example, is then selected (cf. Fig. 9 ). A heating power for the newly set up cooking utensil 14a is then selected by means of the operator interface 12a. In the operating state, only a heating power of a heating power limit value is available for the already set up, with the heating type designated as "Free Control" (FC) heated cooking utensils 14a, which is lower than a heating power selectable in the further operating state for the present heating type. The control unit 16a adapts an input selection of the operator interface 12a in the operating state to prevent the heating output limit value from being exceeded. In a restricted area 24a, the control unit 16a highlights an input selection in the operating state, specifically in a manner analogous to that in FIG Fig. 4 example shown.

Fig. 10 shows a cooking utensil configuration in which a cooking utensil 14a is set up in the vicinity of an already set up, heated cooking utensil 14a with the heating type designated as "normal mode" (NM), for which the heating type designated as "free control" (FC), for example, is subsequently selected will. For the newly set up cooking utensil 14a, only a heating output of a heating output limit value is available, which is smaller than a heating output that can be selected in the further operating state for the present type of heating. In order to prevent the heating output limit value from being exceeded, the control unit 16a adapts an input selection of the operator interface 12a in the operating state, in particular in the same manner as in FIG Fig. 9 cookware configuration shown.

Fig. 11 shows heating power levels of a heating type referred to as "Free Control" before and after a change in the heating power levels by means of the operator interface 12a by an operator. The type of heating known as "Free Control" has, for example, predefined heating power levels of 1/3/5/7/9. Using the operator interface 12a, an operator changes, for example, the predefined heating power levels and creates manually changed heating power levels of, for example, 9/5/9/5/9.

If, for example, in the operating state for a cookware 14a heated with the "Free Control" type of heating, only a heating output of a heating output limit value is available which is less than a heating output that can be selected in the further operating state for the present heating type, the control unit 16a could, for example, all Limit and / or mark heating outputs that exceed the heating output limit value (cf. Fig. 12 ). The control unit 16a could, for example, mask out all heating outputs exceeding the heating output limit value (cf. Figure 12a ). Alternatively, the control unit 16a could, for example, limit all heating outputs exceeding the heating output limit value (cf. Figure 12b ). The control unit 16a could, for example, additionally mark the limited heating outputs, for example by graying out and / or by means of a marking, in particular in the form of an exclamation mark.

Fig. 13 shows two possible outputs via the operator interface 12a in the operating state by the control unit 16a. In the operating state, the control unit 16a could output at least one of the displayed outputs by adapting the operator interface 12a to an operator, in order in particular to notify the operator of a restriction. In order to notify an operator of a restriction that would be made in the course of increasing a current heating output, the control unit 16a in the operating state marks a heating output which assumes the heating output limit value (cf. Figure 13a ). In the operating state, the control unit 16a marks a maximum heating power that can be requested in the operating state with a marking, for example in the form of an exclamation mark. If a heating output is selected in the operating state which is greater than the maximum heating output that can be requested in the operating state, the control unit 16a limits the heating output to the maximum heating output that can be requested in the operating state (cf. Figure 13b ). In the operating state, the control unit 16a marks a limitation of a heating power with a further marking, for example in the form of a further exclamation mark.

Figures 14 to 17 show an example of a change in an adaptation of the operator interface 12a in an operation. For example shows Fig. 14 a cooking utensil 14a, which is heated with the type of heating referred to as "Power Move" (PM), and a cooking utensil 14a, for which the "Free Control" (FC) designated type of heating is selected. For the heating type designated as "Free Control" (FC), only a heating output of a heating output limit value is available, which is lower than a heating output that can be selected in the further operating state for the present heating type, which is why the heating type called "Free Control" (FC) is limited. The limitation of the heating power of the cookware 14a, which is heated with the type of heating referred to as "Free Control" (FC), is provided with a marking by the control unit 16a.

If the cooking utensils 14a heated with the “normal mode” (NM) type of heating are removed (cf. Fig. 15 ), sufficient energy and / or heating power is available for heating the cooking utensils 14a which are heated with the “Free Control” (FC) heating type. The control unit 16a removes the marking of the heating power of the cooking utensils 14a heated with the "Free Control" (FC) heating type in the course of removing the cooking utensils 14a that are heated with the heating type designated as "Normal Mode" (NM). For example, the control unit 16a could automatically remove the limitation of the heating power of the cooking utensils 14a heated with the “Free Control” (FC) heating type in the course of removing the cooking utensils 14a that are heated with the “Normal Mode” (NM) heating type. In the example shown, the control unit 16a maintains the limitation of the heating power of the cookware 14a heated with the type of heating referred to as “Free Control” (FC). In the course of a change in a set-up position of the cookware 14a heated with the "Free Control" (FC) heating type, the control unit 16a changes a heating power with which this cookware 14a is heated depending on a direction of movement of this cookware 14a (cf. Figures 16 and 17 ).

During operation, the control unit 16a takes into account a heating power required for heating. The control unit 16a determines a heating time required for heating to a target heating output, which is in particular greater than a current heating output, as a function of an available heating output of a maximum of one heating output limit value. In one operation, the control unit 16a reserves a heating power component for one type of heating, in particular in order to heat up from a current heating power to a target heating power with the present heating type to ensure, in particular in a, in particular for an operator, acceptable heating-up time.

During operation, when reserving the heating output portion, the control unit 16a takes into account, in particular, that the shorter the heating-up time is required, the more heating output is available until the heating output limit value is reached. During operation, the control unit 16a takes into account that a heating output of at least one minimum heating output limit value should be reserved for heating to a target heating output, since otherwise heating to the target heating output is excluded. During operation, the control unit 16a takes into account that a heating output of at least one preferred heating output limit value, which is in particular greater than the minimum heating output limit value, should be reserved for heating up to a target heating output in a heating time period that is acceptable, in particular for an operator. In order to ensure that cooking utensils 14a, which are heated with the present type of heating, are heated in an acceptable heating time, the control unit 16a reserves a heating power component for the present type of heating in the operating state. This is to be described below with reference to the type of heating referred to as "Sensor Function" (SF), which is shown in Figures 18 and 19 is shown.

Fig. 18 shows a cookware 14a that has already been set up and is heated with the type of heating referred to as "Sensor Function" (SF). In the operating state, the control unit 16a reserves a heating power component for the type of heating with which the cookware 14a that has already been set up is heated. Then a newly set up cooking utensil 14a, for which the type of heating referred to as “normal mode” (NM) is selected, is set up on the hob 10a in a vicinity of the already set up cooking utensil 14a. For the newly set up cooking utensil 14a, only a heating output of a maximum of one heating output limit value is available, which is why the control unit in the operating state adjusts, in particular restricts, an input selection of the user interface 12a for the type of heating that is selected for the newly set up cooking utensil 14a. For the cookware 14a, which is heated with the type of heating referred to as "Sensor Function" (SF), a current heating output is increased to a target heating output which is greater than the current heating output (cf. Fig. 19 ). Due to the reservation of the heating capacity share for the present Heating type of the cooking utensil 14a, which is heated with the heating type referred to as "Sensor Function" (SF), heating of the cooking utensil 14a to the setpoint heating output is guaranteed in an acceptable heating period.

Alternatively, the control unit 16a could output information in particular to an operator via the operator interface 12a. The information could in particular indicate that heating to the target heating power exceeds an acceptable heating time, in particular since only one heating power is available which is in particular smaller than the preferred heating power limit value and advantageously greater than the minimum heating power limit value. As an alternative or in addition, the information could in particular contain an indication that an available heating power can be increased by removing and / or deactivating further cooking utensils 14a and / or by reducing at least one heating output required for further cooking utensils 14a. During operation, the control unit 16a could, depending on a confirmation, in particular from the operator, carry out the heating to the target heating power via the operator interface 12a, in particular despite the heating period exceeding the acceptable heating period.

At least one algorithm for calculating the heating output limit value is stored in the memory unit 20a of the control unit 16a. For example, let T be a selected setpoint temperature in the following. Tgw is, for example, a temperature limit. For example, let P be an available heating power. Pgw is, for example, a heating output limit value. D is, for example, a diameter of a cookware 14a heated with the present type of heating, in particular in the millimeter unit. K1, K2, K3 and K4 are constants, for example. Pgw1 and Pgw2 are, for example, heating output limit values. The control unit 16a takes into account the following formulas in particular.

• T ≤ Tgw
  • P ≥ K1*D - K2
  • für P ≥ Pgw1
• T > Tgw
  • P ≥ K3*D - K4
  • für P ≥ Pgw2

In the event that a selected setpoint temperature is greater than a temperature limit value T> Tgw, the control unit 16a calculates an available heating power P in the operating state as a function of the diameter D of the cooking utensil 14a. The control unit 16a compares the calculated available heating power P with the heating output limit value Pgw. A selected target temperature can be selected for the cookware 14a if the following conditions are met:

• T ≤ Tgw
  • P ≥ K1 * D - K2
  • for P ≥ Pgw1
• T> Tgw
  • P ≥ K3 * D - K4
  • for P ≥ Pgw2

• T ≤ Tgw
  P ≥ K1*D - K2
• T > Tgw
  P ≥ K3*D - K4

A selected target temperature is excluded from a selection for the cookware 14a if the following conditions are met:

• T ≤ Tgw
  P ≥ K1 * D - K2
• T> Tgw
  P ≥ K3 * D - K4

Method according to claim 1, characterised in that the operator interface (12a-b), in order to prevent the heating power limit value from being exceeded, as a function of the present type of heating, is actively adapted by at least one control unit (16a-b) of the hob (10a-b) which is equipped for performing the type of heating and at least one further type of heating.
3. Method according to claim 2, characterised in that the operator interface (12a), in order to prevent the heating power limit value from being exceeded in at least one operation of the hob (10a), is actively adapted by the control unit (16a) as a function of the present type of heating.
4. Method according to claim 3, characterised in that the present type of heating is selected via the operator interface (12a).
5. Method according to claim 2, characterised in that the operator interface (12b), in order to prevent the heating power limit value from being exceeded, is adapted in at least one initialisation step for initialising the hob (10b).
6. Method according to one of the preceding claims, characterised in that the operator interface (12a), in order to prevent the heating power limit value from being exceeded, is adapted differently as a function of at least one cookware configuration.
7. Method according to one of the preceding claims, characterised in that, when preventing the heating power limit value from being exceeded, at least one output is adapted via the operator interface (12a-c).
8. Method according to one of the preceding claims, characterised in that, in order to prevent the heating power limit value from being exceeded, at least one input selection of the operator interface (12a-c) is adapted.
9. Method according to one of the preceding claims, characterised in that at least one heating power component is reserved for at least one type of heating.
10. Hob with at least one control unit (16a-b), which is provided for performing a method according to one of claims 2 to 9.
