FIG. 1 shows a schematic plan view of a hob with a hob device in an operating state, which is integrated in a countertop 48. The hob device has three identical operating elements 10, 42, 43. The operating element 10 is mounted on a functional storage unit 12 of the hob device in a straight line displaceable along a cooking field outer edge 14, which is a leading edge. For this purpose, the operating element 10 is located on a side surface 50 of a hob plate 26 of the hob device ( FIG. 2 ) and is attracted by a fastening means 52, which is formed by a juxtaposition of bar magnets along the cooking field outer edge 14, characterized in that the fastening means 52 attracts a permanent magnet 54 of the operating element 10. Furthermore, a part of the operating element 10 rests on a part of an upper side of the hob plate 26. The side surface 50, the part of an upper side of the hob plate 26 and the fastening means 52 are part of the functional storage unit 12, which supports the operating element 10 detachable without tools from the functional storage unit 12 and the worktop 48. In the operating state, the operating element 10 rests on the work surface 48. Furthermore, in the operating state, the fastening means 52 exerts a magnetic main fastening force on the operating element 10, which pulls the operating element 10 in a direction 16 toward the functional bearing unit 12. To disassemble the operating member 10 from the functional bearing unit 12 without tools, a user exerts a force on the operating member 10 directed away from the functional bearing unit 12, and has to overcome only the main magnetic fixing force and a weight force of the operating member 10 by the force the operating element 10 away from the functional storage unit 12 and the work surface 48 and thus completely disassemble the functional storage unit 12.

The operating element 10 has two identically constructed actuating elements 28, 40, which are designed as circular touch sliders ( FIG. 3 ). The actuator 28 is operable by a user touching the actuator 28, thereby performing a circular motion. By this movement, a cooking stage, on which a cooking zone 56 of the hob device is operated, adjustable. For this purpose, a transmitting unit (not shown) of the operating element 10 sends signals received by the actuating element 28 wirelessly to a receiving unit (not shown) of the functional storage unit 12, which forwards the signals to a control unit (not shown), which adjusts the cooking level by means of the signals. The transmission can be effected in particular by radio and / or by infrared radiation. The cooking stage is displayed by a display unit 36, which is an LCD display. The actuator 28 is operable and the cooking level is adjustable, while the control element 10 relative to the functional storage unit 12 rests or guided by the functional storage unit 12 along the hob outer edge 14 is moved in a straight line. The second actuator 40 is also operable while the actuator 10 rests relative to the functional bearing unit 12. In a plan view of the hob device, the operating element 10 partially covers the hob outer edge 14 (FIG. FIG. 1 ). Further, a portion 60 of the operating member 10 is disposed at a lower level with respect to a vertical direction 58 upwardly in the operating state than a cooking zone upper surface 18 which is a surface portion of the parallelepiped cooking plate 26.

Furthermore, the operating element 10 has a hob main switch 38, by means of which the hob is switched on and off. In principle, it is also conceivable that the operating element 10 is free from the cooktop main switch 38.

In addition, the cooktop device has a second functional storage unit 44, which supports the operating element 42 as functionally coupled to a second cooktop outer edge 46, as the functional storage unit 12 operatively coupled to the control element 10 coupled to the cooktop outer edge 14, wherein the control element 42, the cooktop outer edge 46 in the operating state the plan view partially covered. The functional bearing units 12, 44 and a further functional bearing unit, which supports the operating element 43, are identical.

An energy supply of the operating element 10 is made inductively.
