For example, the sensor unit could have at least one optical sensor and / or at least one weight sensor and / or at least one electronic sensor. In the present embodiment, the sensor unit is partially formed integrally with the heating elements. The Sensor unit is intended to detect by the heating elements set up cooking utensils.

The control unit 12 provides an operator with a catalog of basic recipes 14 by means of the operating unit 18. An operator selects by means of the operating unit 18 a base recipe 14 to be prepared from a catalog of base recipes 14. The catalog of basic recipes represents in particular a selection of at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least seven and particularly preferably at least ten basic recipes.

For example, the catalog of base recipes could be stored on the storage unit of the control unit. In the present exemplary embodiment, the catalog of basic recipes 14 is stored on a further unit 20. The further unit 20 is designed as an external database. The control unit 12 requests a selected base recipe 14 from the further unit 20 as a function of an operating input by means of the operating unit 18. The control unit 12 receives the base recipe 14 from the further unit 20.

In the following, for the sake of clarity and clarity, for example, a basic recipe 14 comprising four recipe parameters will be described on the basis of two exemplary two heating zones. Of course, various, arbitrarily complicated combinations of forms of base recipes 14 and / or heating zones are conceivable. In a method for operating the device 10 for the hob 22, the heating zone-specific parameter 26 is taken into account when the basic recipe 14 is adapted to produce the execution recipe 16.

When adapting a basic recipe 14 to generate an execution recipe 16, the control unit 12 takes into account a plurality of heating zone-specific parameters 26 (cf. Fig. 2 ). For example, one of the heating zone-specific parameters could be a number of heating elements provided for heating a heating zone. In the present embodiment, one of the heating zone-specific parameters 26 is a size of a heating zone. One of the heating zone specific parameters 26 is an extreme heating power associated with a heating zone. In the following, the term "heating zone-specific parameter" 26 in the singular is used as representative of the heating zone-specific parameters 26.

The base recipe 14 has a recipe parameter in the form of a size of a heating zone. The recipe parameter in the form of the size of the heating zone has a value of

Essentially 180 mm up. The base recipe 14 has a recipe parameter in the form of an extreme heat output level associated with the heating zone. The recipe parameter in the form of the heating zone associated extreme Heizleistungsstufe has a value of substantially 6.

The recipe parameter in the form of the time duration has a value of substantially 300 s. The base recipe 14 has a recipe parameter in the form of a portion number. The recipe parameter in the form of the portion number has a value of substantially 4.

In the example considered, the base recipe 14 has the following recipe parameters: Type of recipe parameter Recipe parameter value number of parts essentially 4 Size of the heating zone essentially 180 mm extreme heating power level essentially 6 extreme heating power essentially 200W time essentially 300 s

The control unit 12 receives a recipe parameter to be taken into consideration from the further unit 20. The recipe parameter to be considered is the heating zone-specific parameter 26. The further unit 20 is designed as the sensor unit. Alternatively, the further unit could be designed in particular as a hob electronics (not shown). In the hob electronics in particular technical data of the hob could be stored. The hob electronics and the control unit could be formed separately from each other in particular. Alternatively, the hob electronics could be partially formed integrally with the memory unit of the control unit. The heating zone-specific parameter 26 in the form of the size of the heating zone has a value of substantially 150 mm for a first heating zone. For a second heating zone For example, the heating zone-specific parameter 26 has a value of substantially 210 mm in terms of the size of the heating zone.

Before the adaptation of the basic recipe 14, the control unit 12 issues an operator request for an input of a selection parameter 28. In the present embodiment, the choice parameter 28 is a portion number. The control unit 12 receives a recipe parameter to be taken into account from the further unit 20. The recipe parameter to be considered is the selection parameter 28. The further unit 20 is embodied as the operating unit 18.

The control unit 12 takes into account the selection parameter 28 when adapting the base recipe 14. When adjusting the basic recipe 14, the control unit 12 calculates a heating zone basic quotient from the recipe parameter of the base recipe 14 in the form of the portion number and the recipe parameter of the base recipe 14 in the form of the size of the heating zone , The heating zone base quotient is essentially [4 / (Pi * (0.09) ² )] = 157.19 (1 / m ² ).

When adjusting the basic recipe 14, the control unit 12 calculates a specific heating zone quotient of the selection parameter 28 and the heating zone-specific parameter 26. The control unit 12 compares the heating zone base quotient and the specific heating zone quotient. In adapting the basic recipe 14, the execution recipe 16 control unit 12 selects that heating zone for which a value of a deviation between the specific heating zone quotient and the heating zone basic quotient is minimum.

In a first case, an operator inputs a value of substantially 3 by means of an operating input via the operating unit 18 as an optional parameter 28. In the example considered, the specific heating zone quotient for the size of the first heating zone is essentially [3 / (Pi * (0.075) ² )] = 169.77 (1 / m ² ). For the size of the second heating zone, the specific heating zone quotient is substantially [3 / (Pi * (0.105) ² )] = 86.61 (1 / m ² ). In the example considered, the control unit 12 selects, as a recipe parameter of the execution recipe 16, the size of the first heating zone.

In the present exemplary embodiment, an operator inputs a value of substantially 4 by means of an operating input via the operating unit 18 as a selection parameter 28. The choice parameter 28 in the form of the portion number essentially corresponds to the recipe parameter of the base recipe 14 in the form of the portion number. In the example considered, the specific heating zone quotient for the size of the first heating zone is essentially [4 / (Pi * (0.075) ² )] = 226.36 (1 / m ² ). For the size of the second heating zone is the specific heating zone quotient is essentially [4 / (Pi * (0,105) ² )] = 115.48 (1 / m ² ). In the example under consideration, the control unit 12 selects the size of the second heating zone as the recipe parameter of the execution recipe 16. When adjusting the basic recipe 14, the control unit 12 adjusts the size of the heating zone.

The control unit 12 calculates a maximum selection parameter 28, which is possible given the maximum heating zone-specific parameter 26. The control unit 12 calculates the specific heating zone quotient for a given maximum heating zone-specific parameter 26 for different selection parameters 28. The maximum possible selection parameter 28 for a given maximum heating zone-specific parameter 26 is the one in which the specific heating zone quotient is just smaller than the heating zone base quotient.

The given maximum heating zone specific parameter 26 is given by the size of the second heating zone. In the example considered, a specific heating zone quotient for a choice parameter 28 of substantially 5 is substantially [5 / (Pi * (0.105) ² )] = 144.35 (1 / m ² ). For a choice parameter 28 of substantially 6, the specific heating zone quotient is substantially [6 / (Pi * (0.105) ² )] = 173.22 (1 / m ² ). In the example under consideration, the control unit 12 calculates the dialing parameter 28 of substantially 5 as the maximum dialing parameter 28. In a case where an operator inputs a dialing parameter 28 having a value greater than the maximum dialing parameter 28 through the operator input, the control unit 12 recognizes that the input dialing parameter 28 is greater than the maximum dialing parameter 28. The control unit 12 outputs by means of the operating unit 18 an information to the operator that the input dialing parameter 28 is too large. In the present embodiment, the control unit 12 by means of the operating unit 18 is a proposal for performing a plurality of execution recipes 16 from.

When adjusting the basic recipe 14, the control unit 12 adjusts the heating power. When adjusting the basic recipe 14, the control unit 12 calculates a heat output basic quotient from the recipe parameter of the base recipe 14 in the form of the heating power and the recipe parameter of the base recipe 14 in the form of the size of the heating zone. The heating power base quotient is substantially [200 W / (Pi * (0.09) ² )] = 7859.5 (W / m ² ). The heating power base quotient is a heating power density.

In the adaptation of the basic recipe 14, the control unit 12 calculates a specific heating power quotient of an extreme heating power for a given heating power level and the determined recipe parameter of the execution recipe 16 in the form of Size of the heating zone. For a given heating power level, the control unit 12 reads out a value of heating power from the hob electronics.

In the case of a heating power level of substantially 5, the specific heating power quotient control unit 12 calculates a value of substantially [238 W / (Pi * (0.105) 2)] = 6871.45 (W / m 2). For a heating power level of substantially 6, the specific heating power quotient control unit 12 calculates a value of substantially [258 W / (Pi * (0.105) 2)] = 7448.88 (W / m2). In the case of a heating power level of substantially 7, the specific heating power quotient control unit 12 calculates a value of substantially [280 W / (Pi * (0.105) 2)] = 8084.06 (W / m 2).

The control unit 12 compares the heating power base quotient and the specific heating power quotient with each other. In adapting the basic recipe 14, the execution recipe 16 control unit 12 selects that heating power for which a value of a deviation between the specific heating power quotient and the heating power base quotient is minimum.

In the example considered, the control unit 12 selects the heating power level of substantially 7 as the recipe parameter of the execution recipe 16. The control unit 12 selects, as a recipe parameter of the execution recipe 16, the extreme heating power of substantially 280 W.

When adjusting the basic recipe 14, the control unit 12 adjusts the time duration. When adapting the basic recipe 14 as a function of the determined recipe parameters of the execution recipe 16, the control unit 12 calculates a recipe parameter of the execution recipe 16 in the form of a time duration.

The control unit 12 calculates a specific time duration quotient of the heating power base quotient and the specific heating power quotient when adjusting the basic recipe 14. The control unit 12 calculates the time duration of the execution recipe 16 by multiplying the specific time duration quotient by the time duration of the base recipe 14. In the example considered, the time duration of the execution recipe 16 is substantially [300 s * (7859.5 / 8084.04)] = 291.67 s.

In the example considered, the execution recipe 16 has the following recipe parameters: Type of recipe parameter Recipe parameter value number of parts essentially 4 Size of the heating zone essentially 210 mm extreme heating power level essentially 7 extreme heating power essentially 280W time essentially 291.67 s

After the adaptation of the basic recipe 14 to the preparation of the execution recipe 16, the control unit 12 starts execution of the execution recipe 16. When executing the execution recipe 16, the control unit 12 periodically checks that the recipe parameter values of the execution recipe 16 match the corresponding recipe parameter values of the base recipe 14.

The control unit 12, when adjusting the base recipe 14, calculates an execution base factor from the heating power of the base recipe 14 and the duration of the base recipe 14. When executing the execution recipe 16, the control unit 12 periodically calculates a specific execution factor from a current heating power of the base Execution recipe 16 and a calculated currently planned time duration of the execution recipe 16. The calculated currently planned time period corresponds to the beginning of execution of the execution recipe 16 substantially the calculated time duration of the execution recipe 16. Following a correction of the recipe parameter in the form of the time duration of the execution recipe 16 corresponds to the calculated currently planned time duration of a corrected time duration of the execution recipe 16.

For example, at least one external factor 38 could cause a deviation of the specific execution factor from the execution base factor. The external factor could be, for example, a type of cooking utensil and / or a poor coupling of at least one heating element of the heating zone to a set up cooking utensil and / or a mismatch between an erected cooking utensil and a heating zone associated with the cooking utensil, in particular by a badly positioned one Cookware could be caused. Alternatively or additionally, the external factor could be a type of cooking process, such as, in particular, a dependence of an aim of the cooking process on a time period necessary to achieve the goal.

In the event of a lack of agreement of the recipe parameter values, the control unit 12 automatically performs a correction of the recipe parameter values of the execution recipe 16. When correcting the recipe parameter values of the execution recipe 16, the control unit 12 adjusts the recipe parameter values of the execution recipe 16 to the recipe parameter values of the base recipe 14. In an alternative embodiment, the control unit could output by means of the operating unit a proposal for a correction of at least one recipe parameter value of the execution recipe.

When carrying out the execution recipe 16, the control unit 12 compares a base course 30 of the base recipe 14 with an execution course 32 of the execution recipe 16 (cf. Fig. 3 ). The control unit 12 adjusts the execution profile 32 to the base curve 30 during the correction. In the correction, the control unit 12 adjusts an area below the execution profile 32 to an area below the base course 30.

In the example under consideration, for example, an external factor 38 in the form of a material of a cookware causes a deviation of the execution profile 32 from the base curve 30. The control unit 12 determines the deviation of the execution profile 32 from the base curve 30 at a time t ₀ . The control unit 12 automatically adjusts a correction of the time duration of the execution recipe 16 and the heating power of the execution recipe 16 to produce a correction course 34 of a correction recipe 36 (cf. Fig. 2 and 3 ).

Subsequent to the implementation of the execution recipe 16, the control unit 12 issues an operating request for an evaluation of the execution recipe 16. The control unit 12 requests the operator to evaluate the execution recipe 16 using a point system. The point system has values of 1 to 5 in the present exemplary embodiment. The control unit 12 initiates a correction of the recipe parameters of the base recipe 14 as a function of the evaluation. The control unit 12 transmits a correction information to the further unit 20, in particular in the form of the external database.

Fig. 4 shows a series of recipe steps of the basic recipe 14 in chronological order. The base recipe 14 has a preparation start point, a preparation start point and an end point (see circles with lined hatching). In the example considered has the Base Recipe 14 contains two recipe parameters in the form of recipe steps whose order is unchangeable (see circles with checkered hatching). The basic recipe 14 has three recipe parameters in the form of ingredients (compare circles without hatching). In the example under consideration, the base recipe 14 has three recipe parameters in the form of recipe steps whose sequence can be changed (see circles with goose leg hatching).

Depending on an operating input by means of the operating unit 18, the control unit 12 changes a sequence of recipe steps of the basic recipe 14 (cf. Fig. 4 ). For example, the control unit 12 shifts a recipe step from a time t ₁ , which is temporally prior to a reference recipe step 40, to a time t ₂ , which is later than the reference recipe step 40.

The control unit 12 adds a recipe parameter (not shown) to the base recipe 14 as a function of an operator input by means of the operating unit 18. For example, the control unit 12 adds a recipe parameter to the base recipe 14 in the form of a recipe step. The recipe step could be, for example, searing an ingredient and / or preparing an ingredient and / or turning a food.

Depending on an operating input by means of the operating unit 18, the control unit 12 removes a recipe parameter from the basic recipe 14 (cf. Fig. 4 ). For example, the control unit 12 removes a recipe parameter located at a time t ₃ in the form of an ingredient from the basic recipe 14. The ingredient could be, for example, a spice and / or a side dish and / or a regional specialty and / or a sauce.

In an alternative embodiment, the device for the hob could be part of an electronic device. The control unit of the device could in this case, in particular wirelessly, communicate with a cooktop control unit of the cooktop and, in particular, transmit the execution recipe generated by the control unit on the basis of the basic recipe to the cooktop control unit. In particular, the control unit could check via the cooktop control unit and / or via a sensor unit of the cooktop, a performance of the execution recipe and, if necessary, make corrections to at least one recipe parameter.
