It is further proposed that the air guide unit is provided to divert the vapors into at least one outside area. An “outer area” is to be understood in particular as an area which is arranged outside the outer housing unit in at least one assembled state.

In one installation position, the base housing part in particular absorbs a weight force of the electronics unit at least to a large extent and transmits the weight force received in particular to at least one further unit, such as in particular the hob plate. In at least one assembled state, the electronics unit extends in particular over an area of at least 50%, in particular at least 60%, advantageously at least 70%, particularly advantageously at least 80% and preferably at least 90% of a total area of the base housing part and / or over an area of at least 1800 cm ² , in particular of at least 2150 cm ² , advantageously of at least 2500 cm ² , particularly advantageously of at least 2750 cm ² and preferably of at least 3000 cm ² . As a result, a large-area design and / or secure arrangement of the electronics unit can in particular be made possible.

It is also proposed that, in an installation position, an in particular smallest distance between the fan wheel and the heating element in the vertical direction is a maximum of 70 mm, in particular a maximum of 60 mm, advantageously a maximum of 50 mm, particularly advantageously a maximum of 45 mm and preferably a maximum of 40 mm. In particular, a particularly small distance between the fan wheel and the heating element in the vertical direction is at least 5 mm, in particular at least 10 mm, advantageously at least 15 mm, particularly advantageously at least 20 mm and preferably at least 25 mm. In this way, in particular, a compact design can be achieved.

In addition, it is proposed that, in an installation position, an especially smallest distance between the electronics unit and the heating element in the vertical direction should be at least 70 mm, in particular at least 85 mm, advantageously at least 100 mm, particularly advantageously at least 120 mm and preferably at least 130 mm. In particular, a particularly small distance between the electronics unit and the heating element in the vertical direction is a maximum of 180 mm, in particular a maximum of 200 mm, advantageously a maximum of 210 mm, particularly advantageously a maximum of 220 mm and preferably a maximum of 230 mm. As a result, a spatial separation between the electronics unit and the heating element can be made possible, as a result of which the electronics unit can in particular be arranged in an area in which reaching critical temperatures can be avoided.

It is further proposed that the hob device has at least one hob plate which has at least one extraction recess which is provided for the vapors to pass through. An "extraction recess" is to be understood in particular as an opening and / or a hole in the hob plate through which the fan wheel sucks the vapors out of the cooking space in at least one operating state. In particular, the air guiding unit defines and / or delimits at least one exhaust duct which, in particular in at least one assembled state, connects the exhaust recess and the fan wheel to one another. The air guide unit is provided in particular to connect the cooking space to the fan wheel by means of the exhaust duct. In particular, the exhaust duct is provided to a conduit for the vapors that arise in the operating state. In this way, in particular, a compact design can be achieved.

It is further proposed that the fan wheel is arranged at least partially overlapping with the extraction recess when viewed perpendicularly onto a main plane of extent of the hob plate. The expression that the fan wheel is arranged at least "partially" overlapping with the extraction recess when viewed perpendicularly onto a main extension plane of the hob plate is to be understood in particular as meaning that the fan wheel, when viewed perpendicularly onto a main extension plane of the hob plate, has an area proportion of at least 50 %, in particular of at least 60%, advantageously of at least 70%, particularly advantageously of at least 80% and preferably of at least 90% of a total area of the fan wheel and / or the exhaust recess is arranged overlapping with the exhaust recess. In an installation position, the fan wheel is arranged at least partially below the extraction recess, in particular in the vertical direction. In this way, in particular, a simple suction of the vapors can be achieved, since in particular a short path is provided between the extraction recess and the fan wheel and thus in particular a short path to be covered by the vapors can be made possible.

For example, the extraction unit could only have the fan wheel. The extraction unit preferably has at least one further fan wheel, which is provided to at least partially suck off vapors from the cooking area in at least one operating state and which is arranged in an installation position in the vertical direction between the electronics unit and the heating element. As a result, the vapors can in particular be sucked out of the cooking area particularly quickly, since in particular a high driving force for an extraction can be provided. In the event of failure of one of the fan wheels, a further one of the fan wheels, in particular, can particularly advantageously maintain a cooking mode, as a result of which, in particular, a low probability of a complete failure of the trigger unit can be achieved. In particular, instead of a single, very expensive and high-quality fan wheel, two fan wheels, which are cheaper in comparison, can be used, which in particular makes it possible to achieve low costs.

The fan wheel and the further fan wheel could, for example, be arranged at least partially overlapping with the extraction recess when viewed perpendicularly onto a main plane of extent of the hob plate. As an alternative or in addition, the fan wheel and the further fan wheel could be arranged on, in particular, a single side of the extraction recess when viewed perpendicularly onto a main plane of extent of the hob plate. The fan wheel and the further fan wheel are preferably arranged on opposite sides of the extraction recess when viewed perpendicularly onto a main plane of extent of the hob plate. As a result, in particular, an arrangement of a fan wheel directly below the extraction recess can be dispensed with, as a result of which, in at least one operating state, low noise and a comfortable work can be made possible for an operator, in particular while avoiding noise nuisance.

It is also proposed that the extractor unit have at least one grease filter unit which, in particular in an installation position, has a minimum distance from an upper edge of the hob plate of a maximum of 70 mm, in particular of a maximum of 50 mm, advantageously of a maximum of 40 mm, particularly advantageously of a maximum of 30 mm, preferably of a maximum of 20 mm and particularly preferably of a maximum of 10 mm. In this way, in particular, a particularly compact design can be achieved.

The hob device is not intended to be restricted to the application and embodiment described above. In particular, the hob device can have a number of individual elements, components and units that differs from a number of individual elements, components and units mentioned herein in order to fulfill a mode of operation described herein.

The take-off unit 14b has an impeller 16b and a further impeller 40b. In one operating state, the fan wheel 16b and the further fan wheel 40b partially suck off vapors that arise in the operating state from a cooking area 18b.

In one installation position, the impeller 16b and the further impeller 40b are arranged in a vertical direction 22b between an electronic unit 20b and the heating element 12b. In a horizontal direction 56b, the fan wheel 16b and the further fan wheel 40b are arranged on opposite sides of an extraction recess 38b of the hob plate 36b when viewed perpendicularly onto a main plane of extension of a hob plate 36b.

The take-off unit 14b has an air guiding unit 24b. In an assembled state, the air guiding unit 24b surrounds the fan wheel 16b and the further fan wheel 40b with respect to a center point and / or center of gravity of the fan wheel 16b and / or the further fan wheel 40b viewed in a plane which, in particular, is aligned parallel to a main plane of extent of the hob plate 36b, essentially completely.

An exhaust air recess 60b of the air guiding unit 24b is arranged essentially centrally in a horizontal direction 56b, in particular with respect to an extension of the hob plate 36b in the horizontal direction 56b. When viewed in a viewing direction aligned parallel to a depth direction 58b, the exhaust air recess 60b of the air guiding unit 24b and an exhaust air recess 62b of the outer housing unit 28b are partially overlapping with one another.
