This makes it possible for the illumination strip 20a to be assembled flexibly on any side of the hob, these in particular being arranged in mutually opposing end regions of the hob outer housing unit 40a in relation to a transverse direction.

[0093] In a method for operating the hob device 10a, half of all the heating units 16a are marked by means of a single illumination strip 20a in an operating state (see FIGS. 1 and 11 to 17).

[0094] For example, in an operating state, two items of cookware 14a are placed on the placement plate 12a (see FIG. 1). In an operating state, the illumination strip 20a indicates an extension 74a, 86a of each item of cookware 14a of the items of cookware 14a in relation to a direction 18a. In an operating state, the illumination strip 20a indicates an extension 74a of a first item of cookware 14a of the items of cookware 14a in the direction 18a. In an operating state, the illumination strip 20a indicates an extension 86a of a second item of cookware 14a of the items of cookware 14a in the direction 18a. The extension 74a of the first item of cookware 14a in the direction 18a is smaller than the extension 86a of the second item of cookware 14a in the direction 18a.

[0095] In addition to the extension 74a, 86a of the item of cookware 14a in relation to the direction 18a, in an operating state the illumination strip 20a indicates a position of each item of cookware 14a of the items of cookware 14a in relation to the direction 18a.

[0096] In an operating state, the illumination strip 20a indicates a heating state of the item of cookware 14a (see FIG. 1). In an operating state, the illumination strip 20a indicates the heating state of the item of cookware 14a, in particular embodied as a heating output, with varying colors. For example, the illumination strip 20a indicates a high heating state, in particular embodied as heating output, with a different color than a low heating state, in particular embodied as heating output. The different colors are characterized in FIG. 1 by different densities of hatch markings, wherein a dense hatch marking is assigned a high heating output and a broad hatch marking is assigned a low heating output.

[0097] For example, starting from the configuration from FIG. 1, an item of cookware 14a of the items of cookware 14a is removed from the placement plate 12a (see FIG. 11). In an operating state, the illumination strip 20a indicates a heating state embodied as residual heat. The illumination strip 20a indicates the heating state, in particular embodied as residual heat, even after the item of cookware 14a has been removed from the placement plate 12a, specifically in particular until a residual heat falls below a threshold value. For example, the illumination strip 20a indicates a high heating state, in particular embodied as residual heat, with a different color than a low heating state, in particular embodied as residual heat.

[0098] In an operating state, the illumination strip 20a indicates a movement of the item of cookware 14a from a first placement position 78a to a second placement position 80a (see FIGS. 12 and 13). In an operating state, the illumination strip 20a indicates the movement of the item of cookware 14a by deactivating the illumination of the first placement position 78a and activating an illumination of the second placement position 80a. Before activating the illumination of the second placement position 80a, in an operating state, the illumination strip 20a indicates an operating prompt by changing an illumination property. In an operating state, before activating the illumination of the second placement position 80a, the illumination strip 20 indicates an animation, in order to transmit the operating prompt to the user in particular. In the present exemplary embodiment, the operating prompt is a prompt for confirming a movement of the item of cookware 14a from the first placement position 78a to a second placement position 80a.

[0099] In an operating state, the illumination strip 20a indicates a direction of movement 76a, in which the item of cookware 14a can be moved (see FIGS. 14 to 16). In an operating state, the illumination strip 20a indicates the direction of movement 76a by means of an intensity curve, specifically in particular by means of an intensity gradient. If, for example, an item of cookware 14a is placed in a rear region of the placement plate 12a, then the illumination strip 20a indicates the direction of movement 76a in the direction of a front region of the placement plate 12a (see FIG. 14). If, for example, an item of cookware 14a is placed in a front region of the placement plate 12a, then the illumination strip 20a indicates the direction of movement 76a in the direction of a rear region of the placement plate 12a (see FIG. 15). In the case of an item of cookware 14a, which is arranged in a central region of the placement plate 12a, the illumination strip 20a indicates the direction of movement 76a in the direction of a rear region of the placement plate 12a and in the direction of a front region of the placement plate 12a (see FIG. 16).

[0100] In a method for operating the hob device 10a, in an operating state, an extension 74a of the item of cookware 14a in relation to the direction 18a is indicated by means of the illumination strip 20a.

[0101] In an operating state, the illumination strip 20a indicates an in particular predefined heating output, which varies in the direction 18a, in particular in addition or as an alternative to the extension 74a of the item of cookware 14a, in relation to the direction 18a (see FIG. 17). If, for example, an in particular predefined heating output in a front region of the placement plate 12a is greater than in a rear region of the placement plate 12a and the heating output decreases, in particular monotonically, from the front region in the direction of the rear region, then the illumination strip 20a indicates, in relation to the direction 18a, the in particular predefined heating output, which varies in the direction 18a, by means of an intensity curve and/or by means of a color curve and/or by means of a brightness curve.
