The heating power densities of a majority of the heating elements 12a, that is, each of the heating elements 12a, are different from each other. The control unit 16a operates in an operating mode the heating elements 12a depending on the position with predefined, from each other

different heating power densities. A predefined heating power density of a heating element 12a arranged in the installed state in the area facing the operator is greater than a predefined heating power density of a heating element 12a

built-in state in the area facing away from the operator area heating element 12a. In the operating mode, the control unit 16a orders one

Heating element 12a, which is arranged in the area facing the operator, a higher Heizleistungsdichte than a heating element 12a, which is arranged in the area facing away from an operator.

The hob device 10a has in an installed state an operator assigning area on a control unit 22a to an input of Betriebspara meiern on. For example, the operating unit is provided for selecting and / or changing a heating zone. In addition, the operating unit could be provided for setting a heating power and / or heating power density of a heating zone. It is also conceivable that the operating unit is designed to select and / or change a cooking time and / or a cooking program. Furthermore, it is conceivable that the

Operating unit is provided for a change of an operating mode and / or operating state. Alternatively, further embodiments of the operating unit and / or the operating parameter that appear appropriate to a person skilled in the art are conceivable. The

Hob device 10a has a control unit 16a which is provided to execute actions and / or to change settings in dependence on the operating parameters entered by means of operating unit 22a.

The control unit 16a changes in dependence on an operator input by means of the operating unit 22a, a predefined stored in the storage unit

Heat density of one of the heating elements 12a. Upon a change in a predefined heating power density of a first heating element 12a, the control unit 16a changes as a function of the change in the predefined heating power density of the first

Heating element 12a heating power densities of the other three heating elements 12a, which together with the first heating element 12a forming the variable cooking surface area 24a. In addition, the control unit 16a changes depending on one

Operating input by means of the operating unit 22a between the first operating mode, in which the heating elements 12a are operated depending on position with predefined, mutually differing Heizleistungsdichten, and a second Operating mode in which the heating elements 12a are operated with mutually independent heating power densities. In the first operating mode, a heating element 12a arranged in the area in the installed state facing an operator has a largest predefined heating power density of the heating elements 12a forming the variable cooking surface area 24a. The heating power densities of the others

Heating elements 12a decrease in the direction of the row longitudinal direction 36a. Depending on an operating input by means of the operating unit 22a, the control unit 16a alters an assignment of the predefined, mutually differing heating power densities to the individual heating elements 12a. After an operator input by means of

Operating unit 22a has an operator in the installed state

facing area arranged heating element 12a a smallest predefined

Heat density of the variable cooking surface area 24 a forming

Heating elements 12a on. The heating power densities of the further heating elements 12a increase in the direction of the row longitudinal direction 36a.

2 shows a hob 28b according to the invention, which is designed as an induction hob, with a hob device 10b according to the invention, which is designed as an induction hob device. The hob apparatus 10b includes four heating elements 12b for heating up cooking utensils 14a. The

Heating elements 12b, which are designed as induction heating elements, are arranged below a main body 30b. The heating elements 12b are designed as classic heating elements 12b. In each case two of the heating elements 12b are with respect to a

Row longitudinal direction 36b arranged one behind the other. The heating elements 12b form a classic hob 26b. The hob device 10b comprises a sensor unit for detecting mounted cooking utensils 14b. In a method of operating the cooktop apparatus 10b, the sensor unit detects a first position 18b of an erected cooking utensil 14b. The hob device 10b includes a control unit 16b that activates heating elements 12b associated with the first position 18b of the cooking utensil 14b. In the event of a change from the first position 18b of the cooking utensil 14b to a second position 20b of the cooking utensil 14b, the control unit 16b deactivates a first heating element 12b associated with the first position 18b of the cooking utensil 14a and activates a second heating element associated with the second position 20b of the cooking utensil 14b 12b with different heating power density than the first heating element 12b (see Fig. 4). It is conceivable that - for example, in the case of more than four heating elements, with three

Heating elements are arranged one behind the other with respect to the row longitudinal direction - the control unit in the event of a change from the first position of the cooking utensil to a second position of the cooking utensil, a heating element in the activated state in the first position of the cooking utensil and the second position of the cooking utensil covered by the cookware, with altered different

Heated power density reactivated.

The control unit 16b operates a heating element 12b assigned to a set cooking utensil 14b as a function of a position 18b, 20b of the cooking utensil 14b with a different heating power density. The control unit 16b operates the heating elements 12b with respect to the row longitudinal direction 36b with different heating power densities. Here, the control unit 16b operates in a built-in state in a

Operator facing area arranged heating element 12b with different Heizleistungsdichte than one in the installed state in an operator

remote area arranged heating element 12b. The control unit 16b comprises a memory unit in which a heating power density is stored for each heating element 12b as a function of a position of the heating element 12b. The heating power densities of a majority of the heating elements 12b, that is, each of the heating elements 12b, are different from each other. The control unit 16b operates in a mode of operation the heating elements 12b position-dependent with predefined, from each other

different heating power densities. In the operating mode, the control unit 16b places a heating element 12b in the area facing an operator is arranged to a higher Heizleistungsdichte than a heating element 12b, which is arranged in the area facing away from the operator.

The control unit 16b changes in dependence on an operator input by means of a control unit 22b, a predefined stored in the storage unit

Heat density of one of the heating elements 12b. Upon a change in a predefined heating power density of a first heating element 12b, the control unit 16b changes as a function of the change in the predefined heating power density of the first

Heating element 12b has a heating power density of the further heating element 12b, which is arranged with respect to the row longitudinal direction 36b nearest to the first heating element 12b. Depending on an operating input by means of the operating unit 22b, the control unit 16b changes an assignment of the predefined, mutually differing heating power densities to the individual heating elements 12b. In addition, the control unit 16b changes as a function of an operating input by means of the operating unit 22b between the first operating mode, in which the heating elements 12b position-dependent with predefined, mutually different

Heating power densities are operated, and a second operating mode in which the heating elements 12b are operated with independent heating power densities.

Fig. 5 shows a hob 28c with a hob device 10c. Hob device 10c includes a plurality of heating elements 12c for heating upright

Garware 14c, 46c, 48c. In an installed position, the heating elements 12c are arranged below a main body 30c. The main body 30c is designed as a hob plate. The heating elements 12c form a variable cooking surface area 24c. The heating elements 12c forming the variable cooking surface area 24c are arranged in the form of a cooktop matrix. Here, the heating elements 12c are arranged in columns and rows. In the present embodiment, the term "matrix" is in

to understand mathematical sense. In an alternative embodiment, it is conceivable that columns and / or rows of a cooktop matrix are arranged offset from one another. In Fig. 6 to 1 1 has been dispensed with a representation of the heating elements 12c for clarity.

Hob device 10c includes a control unit 16c that activates first heating elements 12c associated with a method for operating a first position 18c of topped cooking utensil 14c (see Figure 6). In the event of a change from the first Position 18c of the cooking utensil 14c to a second position 20c of the cooking utensil 14c, the control unit 16c deactivates at least one first heating element 12c associated with the first position 18c of the cooking utensil 14c and activates at least one second heating element 12c having a different heating power density than the second position 20c of the cooking utensil 14c at least a first heating element 12c. Here, the control unit 16c reactivates at least one heating element 12c which is in the activated state and which is covered by the cooking utensil 14c in the first position 18c of the cooking utensil 14c and the second position 20c of the cooking utensil 14c, with a different heating power density. A case of a change from the second position 20c of the cooking utensil 14c to a third position 42c of the cooking utensil 14c is analogous to the case of a change from the first position 18c of FIG

Garware 14c to the second position 20c of the cooking utensil 14c.

In an operating mode, the control unit 16c operates heating elements 12c assigned to an installed cooking utensil 14c as a function of a position 18c, 20c, 42c of the cooking utensil 14c with a different heating power density. The control unit 16c operates the heating elements 12c in the operating mode in a position-dependent manner with predefined, mutually differing heating power densities. In the operating mode, the control unit 16c changes the predefined heating power densities of the heating elements 12c as a function of an operating input by means of an operating unit 22c. In a

Storage unit of the control unit 16 c are stored a plurality of configurations of predefined heating power densities of the heating elements 12 c. In each of the configurations, the heating elements 12c are dependent on the position of the corresponding one

Heating element 12c assigned a Heizleistungsdichte. In addition to the stored configurations, it is conceivable that an operator can create further configurations by means of an operating input by means of the operating unit.

The control unit 16c retains given predefined heating power densities

Heating elements 12c so long until a change in at least one Heizleistungsdichte one of the heating elements 12c by an operator input by means of the control unit 22c occurs. For example, the control unit could be given predefined

Keep heating power densities of the heating elements 12c beyond a rest phase. In particular, the rest phase could occur for example by a deactivation of the hob and / or a power failure and / or an emergency shutdown. According to a first configuration, in the heating mode operating mode 12c, which are arranged in an operator-facing area, the control unit 16c allocates a higher heating power density than heating elements 12c arranged in an operator-facing area (see FIG. By changing a position 18c, 20c, 42c of the cooking utensil 14c in a depth direction 40c, in the FIG

Operating mode, a heating power density supplied to the cooking utensil 14c in dependence on the position 18c, 20c, 42c of the cooking utensil 14c are reduced (see Fig. 6). Such a change of a position 18c, 20c, 42c of the cooking utensil 14c in the depth direction 40c could be done, for example, from the first position 18c of the cooking utensil 14c to the third position 42c of the cooking utensil 14c. The depth direction 40c is aligned in an installed position from the area facing an operator in the direction of the area facing away from the operator.

In the case of a change from a first position 18c of the cooking utensil 14c to a second position 20c of the cooking utensil 14c opposite to the depth direction 40c, the control unit 16c operates a heating element 12c having a higher heating power density associated with the second position 20c of the cooking utensil 14c than a first position 18c of the cooking utensil 14c associated heating element 12c (see Fig. 7). When changing from the first position 18c of the cooking utensil 14c to a third position 42c of the cooking utensil 14c, the control unit 16c operates a heating element 12c of higher heating power density associated with the first position 18c of the cooking utensil 14c than a heating element 12c associated with the third position 42c of the cooking utensil 14c. Starting from the first position 18c of the cooking utensil 14c, the third position 42c of the cooking utensil 14c is arranged in a direction which is aligned obliquely to the depth direction 40c and is directed towards the area facing away from the operator.

If, for example, a second cooking utensil 46c is placed adjacent to the third position 42c of the cooking utensil 14c, the control unit 16c in the operating mode operates a heating element 12c which is associated with the second cooking utensil 46c, in FIG

Substantially same heating power density as a heating element 12c associated with the cooking utensil 14c set up at the third position 42c of the cooking utensil 14c (see Fig. 7). For example, a third cooking utensil 48c is set at substantially the same height as the second position 20c of the cooking utensil 14c. The third cooking utensil 48c is in an orthogonal direction 44c to the second position 20c of the

Garware 14c arranged adjacent. A distance of the third cooking harness 48c from a leading edge of the main body 30c is substantially equal to a distance of the second position 20c of the cooking utensil 14c from the front edge of the main body 30c. In the mode of operation, the control unit 16c operates a heating element 12c associated with the third cooking utensil 14c with substantially the same heating power density as a heating element 12c at the second position 20c of the cooking utensil 14c

associated cookware 14c is associated.

For example, in the operation mode, an operator changes the predefined heating power densities of the heating elements 12c by an operation input by the operation unit 22c, and selects a second configuration. The control unit 16 c orders in the

Operation mode the heating elements 12c in a bias direction, which includes a Wnkel between 10 ° and 80 ° with the depth direction 40c, different heating power densities (see Fig. 8). In the present embodiment, in the operation mode, the control unit 16c places a highest one on a first heating element 12c disposed in the area facing the operator in a corner of the cooking surface area 24c

Heating power density too. Heating elements 12 c, which are spaced in the depth direction 40 c to the first heating element 12 c, assigns the control unit 16 c in the operating mode lower heating power densities than the first heating element 12 c. By doing

Operating mode, the control unit 16 c heating elements 12 c, which in a

Orthogonalrichtung 44c are spaced from the first heating element 12c, lower heating power densities than the first heating element 12c. The orthogonal direction 44c is oriented perpendicular to the depth direction 40c.

For example, a cooking utensil 14 c is in a vicinity of the first heating element 12 c, which in the area facing the operator in a corner of the

Cooking surface portion 24c is disposed at a first position 18c of the cooking utensil 14c. In the event of a change from the first position 18c of the cooking utensil 14c to a second position 20c of the cooking utensil 14c in a first oblique direction which makes an angle of substantially 40 ° with the depth direction 40c, the control unit 16c operates one of the first position 18c of FIG Garder 14c associated heating element 12c with higher heating power density than a second position 20c of the cooking utensil 14c associated heating element 12c (see Fig. 8). In a change from the second position 20c of the cooking utensil 14c to a third position 42c of the cooking utensil 14c in a second oblique direction including an angle of substantially 55 ° with the depth direction 40c, the control unit 16c operates one of the second position 20c heating element 12c associated with the cooking utensil 14c with a higher heating power density than a heating element 12c associated with the third position 42c of the cooking utensil 14c.

In response to an operation input by the operation unit 22c through which an operator selects another configuration, in the operation mode, the control unit 16c changes the predefined heating power densities of the heating elements 12c.

For example, in the heating mode operating mode 12c disposed in a first side area of the variable cooking surface area 24c, the control unit 16c allocates higher heating power densities than heating elements 12c disposed in a second side area of the variable cooking surface area 24c (see FIG. 9). , The first area of the variable cooking surface area 24c and the second area of the variable cooking area area 24c are arranged opposite to each other. The second area of the variable cooking surface area 24c is spaced apart in the orthogonal direction 44c from the first area of the variable cooking surface area 24c. In the operating mode, the control unit 16c operates a second heating element 12c, which in the orthogonal direction 44c has a greater distance from the first lateral area of the variable cooking surface area 24c than a first heating element 12c, with a lower heating power density than the first heating element 12c.

If an operator changes the predefined heating power densities of the heating elements 12c by operating input by means of the operating unit 22c in the operating mode, the control unit 16c operates the heating elements 12c as a function of the operating input by means of the operating unit 22c in a position-dependent manner with predefined ones different from each other

Heating power densities. For example, in the operating mode, the control unit 16 c arranges a heating element 12 c that is substantially in a center of the variable

Cooking surface area 24c, a higher Heizleistungsdichte than

Heating elements 12c disposed within concentric paths around the heating element 12c located substantially in the center of the variable cooking surface area 24c (see Fig. 10). In the operation mode, the control unit 16c assigns a highest heating power density to the heating element 12c disposed substantially in the center of the variable cooking surface area 24c. The control unit 16c, in the operating state, sets heating elements 12c arranged within a first concentric path about the heating element 12c located substantially in the center of the variable cooking surface area 24c to have the same heating power density as that substantially in the center of the variable cooking surface area 24c arranged heating element 12c. In the present embodiment, the control unit 16c selects a radius of the first concentric path in a range of a diameter of the cooking utensil 14c that is on the substantially in the center of the variable

Cooking surface area 24c arranged heating element 12c is set up (see Fig. 10). The control unit 16c assigns a lower heat power density to heating elements 12c disposed in a region between the first concentric sheet and a second concentric sheet directly adjacent to the first concentric sheet than heating elements disposed within the first concentric sheet 12c. In the operation mode, the control unit 16 c orders one

Heating element 12c, which is arranged between two concentric paths, which have a smaller distance from the heating element 12c arranged substantially in the center of the variable cooktop area 24c than a heating element 12c, which is arranged between two further concentric paths, a larger one

Heat density to as the heating element 12c, which is arranged between the two other concentric tracks.

In another case, an operator selects by an operator input by means of the

Operation unit 22 c of another configuration of the stored in the memory unit of the control unit 16 c configurations. The control unit 16 c orders in the

Operation mode heating elements 12c, which are partially covered by a cooking utensil 14c, to a higher Heizleistungsdichte than heating elements 12c, which within concentric paths to those of the cooking utensil 14c partially covered

Heating elements 12c are arranged. Here, the cooking utensil 14c may be placed at any position 18c, 20c, 42c. When setting up a second cooking utensil 46c between a first concentric path around the cooking utensil 14c and a second concentric path located immediately adjacent the first concentric path, the control unit 16c places heating elements 12c partly covered by the second cooking utensil 46c lower heating power density than

Heating elements 12c, which are partially covered by the cooking utensil 14c and arranged in particular within the first concentric path. In the mode of operation, the control unit 16c arranges heating elements 12c, that of a third cooking utensil 48c, between the second concentric path around the cooking utensil 14c and a third concentric path directly adjacent to the second concentric path is disposed, partially covered, a lower heating power density than heating elements 12c, which are arranged between the first concentric path and the second concentric path.
