The drawing, the description and the claims contain numerous features in combination. A person skilled in the art will also consider the features individually as appropriate, and combine them in further suitable combinations.

    [0020] FIG. 1 shows a cooktop with a cooktop device in a schematic plan view,

    [0021] FIG. 2 shows a section of the cooktop with the cooktop device in a schematic plan view, wherein a cooktop plate is not illustrated,

    [0022] FIG. 3 shows a section of the cooktop device in a schematic side view, and

    [0023] FIG. 4 shows a section of an alternative cooktop device of an alternative cooktop in a schematic side view.

    [0024] FIG. 1 shows a cooktop 36 which is embodied as an induction cooktop, having a cooktop device 10 that is embodied as an induction cooktop device. The cooktop device 10 comprises a cooktop plate 38. The cooktop plate 38 is designed for the placement of cooking utensils. In an assembled state, the cooktop plate 38 forms part of an outer housing, and in particular an outer housing of the cooktop 36.

    [0025] The cooktop device 10 comprises a plurality of heating elements 24 (cf. FIG. 2). In the present exemplary embodiment, the cooktop device 10 comprises three heating elements 24. Alternatively, the cooktop device could have fewer heating elements, e.g. exactly one heating element or two heating elements. In an alternative embodiment, the cooktop device could comprise at least four and in particular at least five heating elements. The heating elements 24 are so arranged as to be mobile. The heating elements 24 define a variable cooking surface area 44. The variable cooking surface area 44 extends over a large part of a surface extent of the cooktop plate 38. According to the invention, the variable cooking surface area 44 extends over at least 60%, in particular at least 70%, advantageously at least 75% and preferentially at least 80% of a surface extent of the cooktop plate 38. In the following, only one of the heating elements 24 is described. The heating element 24 is designed to heat a cooking utensil which has been placed on the cooktop plate 38.

    [0026] The cooktop device 10 comprises an operating unit 40 for entering and/or selecting operating parameters (cf. FIG. 1), e.g. a heat output and/or a heat output density and/or a heating zone. The operating unit 40 is designed to output a value of an operating parameter to a user.

    [0027] The cooktop device 10 comprises a control unit 42. The control unit 42 is designed to execute actions and/or change settings as a function of operating parameters that have been entered by means of the operating unit 40. In a heating mode, the control unit 42 controls an energy supply to the heating element 24.

In the operating state, the control unit 42a moves the heating element 24a in a plane which is aligned largely parallel to a main plane of extension of the cooktop plate 38a. In the operating state, the heating element 24a can be moved in two degrees of freedom by the control unit 42.

    [0029] The heating element 24 is designed to heat a plurality of cooking utensils simultaneously. For example, it is assumed that two cooking utensils are placed. In the event that two cooking utensils have been placed, the control unit 42 determines a frequency of movement of the heating element 24 between a position of a first cooking utensil and a position of a second cooking utensil. Heating two or more cooking utensils using one heating element 24 is known from the prior art and is not a fundamental aspect of this invention. It is therefore not described in further detail in the following.

    [0030] The cooktop device 10 comprises a base component 22 (cf. FIG. 2). The base component 22 is embodied as a housing component. The base component 22 and the cooktop plate 38 together form the outer housing.

The sections 50, 52, 54 are rigidly connected together. In the present exemplary embodiment, the sections 50, 52, 54 are embodied as a unitary part. The third section 54 is oriented largely perpendicular relative to the first section 50 and the second section 52. In the assembled state, the first section 50 has a greater distance from the floor of the base component 22 than the second section 52. The distance here is oriented largely parallel to a vertical direction 56. In the assembled state, the vertical direction 56 is oriented largely perpendicular to a main plane of extension of the base component 22. In the assembled state, the vertical direction 56 is oriented largely perpendicular to a main plane of extension of the cooktop plate 38. In an installed position, the vertical direction 56 is oriented largely parallel to a direction of gravitational force. In the assembled state, the vertical direction 56 points from the cooktop plate 38 toward the base component 22. Viewed from the side, the first arm part 14 has a stepped shape.

    [0036] In the assembled state, a main direction of extension of the first section 50 and a main direction of extension of the second section 52 are oriented largely parallel to each other.
