In the case of a heating parameter, which is a heating power and / or a heating power density and / or a heating power stage, the operating mode could in particular be an operating mode, referred to as "power-move", in which, in particular

Change of the heating parameter by a shift of the cooking utensils in the

Heating area, in particular along the direction, can be made. In the case of a heating parameter, which is a temperature, the operating mode could in particular be an operating mode designated as "temperature-move", in which, in particular, a change of the heating parameter is caused by a shift of the heating parameter

Garware in the heating area, in particular along the direction, can be made. As a result, it is possible, in particular, to create a possibility of optimum marking of an operating mode designated as "power move" and / or as "temperature move". It is also proposed that the heating area comprises at least one composite heating zone. In particular, the heating region, advantageously the composite heating zone, is defined by at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least seven and particularly preferably a plurality of heating units. For example, the heating area could consist of the composite heating zone and in particular of the

be defined composite heating zone defining heating units. Advantageously, the heating area is in addition to the composite heating zone defining

The heating zone, in particular a size of the heating zone and / or a shaping of the heating zone, is defined in particular by the heating unit, in particular by a size of the heating unit and / or by a shape of the heating unit, which supplies energy to the heating zone in the heating operating state. In particular, the heating zone, in particular a size of the heating zone and / or a shaping of the heating zone, is at least substantially independent of a set up cooking utensil, in particular of a size of an erected cooking utensil and / or a shape of an erected cooking utensil. For example, the heating area, which could in particular comprise a composite heating zone, could be defined by at least two heating units and in particular form a variable cooking surface. The heating units could in this case in particular be arranged in a row and / or in the form of a cooktop matrix. Alternatively, the

Display unit and / or by at least one display element of the display unit, such as an LED. In particular, a classic cooktop differs from a matrix cooktop. A matrix cooktop differs in particular from a classic cooktop through a variable cooktop. As a result, in particular garnishes of different sizes can be heated and / or heated by means of the heating area. In addition, it is proposed that the control unit is provided in the

Operating mode by means of the marking to mark a boundary of the heating at least partially. For example, the control unit could be provided to at least substantially completely mark a surfacing of the heating area in the operating mode by means of the marking. The control unit is in particular intended to mark the heating area at least in sections in the operating mode by means of the marking. In particular, the

Control unit provided to identify in the operating mode corner points of the heating area by means of the marking and in particular to identify shortest connections between the vertices at least in sections and / or at least partially leave unmarked. In particular, the

Control unit provided in the operating mode, the shortest connections between the vertices to a proportion of at least 30%, in particular of at least 40%, advantageously at least 50%, more preferably at least 60% and preferably at least 70% of a longitudinal extension of the shortest connections between the vertices unmarked. When viewing a projection in a plane, which is aligned in particular parallel to a main extension plane of the hob plate, the boundary of the heating area is in particular a circumference of the heating area. As a result, optimal marking of the heating area can be made possible, especially at low cost.

Low costs can be achieved in particular by a possibility to arrange at least a part of the display unit in a region between at least two heating units defining the heating area, such as at least one

Display element, in particular an LED.

Furthermore, it is proposed that the control unit is provided in the

Operating mode at least one position of individual defining the heating area

Be provided control unit, in particular in addition to a marking of the boundary of the heating area, the position of the heating area defining

Mark heating units by marking a boundary of the heating unit defining heating units. Alternatively or additionally, the

Control unit be provided to mark at least one position of a center of gravity and / or a center of the heating area defining heating units by means of the marking. As a result, cooking utensils can be placed specifically on the appropriate heating units, in particular as a function of a size of individual heating units defining the heating area, as a result of which a heating zone suitable for heating a given cooking utensil can be optimally selected in a simple manner. It is also proposed that the control unit be provided in the

Operating mode to indicate at least one temperature of a particular activated and / or deactivated heating zone of the heating area by means of the marking, in particular by means of the marking property. The temperature of the heating zone is in particular a temperature of a surface of the heating zone arranged in the region of

Heating area, which is formed in particular by a surface of the hob plate. For example, the control unit could in particular be additionally provided, in the operating mode, at least one residual heat of a particular deactivated heating zone of the heating area by means of the marking, in particular by means of the

Marker feature, display. In particular, the control unit could be provided to reduce an intensity of the marking monotonically, in particular linear, with decreasing temperature in the operating mode. In particular, a temperature of a deactivated heating zone decreases with increasing time interval between the deactivation of the deactivated heating zone and a time of displaying the temperature of the deactivated heating zone. This can in particular a high
