In the operating state, for example, the plane could be aligned at least essentially parallel to a main extension plane of the mounting plate. The level could be in the operational state for example be aligned at least substantially perpendicular to a main plane of extension of the mounting plate.

The impeller encloses the space in particular in at least one plane, which is in particular aligned at least essentially parallel to a main extension plane of the mounting plate, over an angular range of at least 90°, in particular of at least 180°, advantageously of at least 270°, particularly advantageously of at least 300 °, preferably at least 330 ° and particularly preferably at least 350 °. For example, the impeller could completely enclose the space and in particular have a cylindrical shape. Advantageously, the impeller partially encloses the space and in particular has the shape of a cylinder jacket. The space is in particular unlimited on a side of the impeller facing the mounting plate and/or on a side of the impeller facing away from the mounting plate, in particular by the impeller.

“Essentially parallel” is to be understood here in particular as an orientation of a direction relative to a reference direction, in particular in a plane, with the direction having a deviation from the reference direction of in particular a maximum of 8°, advantageously a maximum of 5° and particularly advantageously a maximum of 2° . The expression “essentially perpendicular” is intended here to define in particular an alignment of a direction relative to a reference direction, with the direction and the reference direction, viewed in particular in one plane, enclosing an angle of 90° and the angle has a maximum deviation of in particular a maximum of 8° , advantageously at most 5° and particularly advantageously at most 2°.

“Provided” is to be understood in particular as being specially designed and/or equipped. The fact that an object is provided for a specific function is to be understood in particular to mean that the object fulfills and/or executes this specific function in at least one application and/or operating state.

Furthermore, it is proposed that the impeller has at least one base element, from which at least a plurality of fan blade elements of the impeller protrude, which at least partially enclose and/or delimit the space. In particular, the impeller has at least a plurality of fan blade elements, advantageously at least the plurality of fan blade elements. A "plurality" should in particular include a number of at least four, in particular at least five, advantageously at least six, particularly advantageously at least eight, preferably at least ten and particularly preferably at least twelve. The fan wheel advantageously has a large number of fan blade elements. In particular, the fan blade elements are aligned at least substantially parallel to one another. For example, the fan blade elements could be aligned at least essentially parallel to a main plane of extension of the mounting plate and in particular at least partially enclose the space in at least one direction, which could in particular be aligned at least essentially perpendicular to a main plane of extension of the mounting plate. The fan blade elements could, for example, be oriented obliquely relative to a main plane of extension of the mounting plate and in particular at least partially enclose the space in at least one direction, which could in particular be oriented obliquely relative to a main plane of extension of the mounting plate. Advantageously, the fan blade elements could be oriented at least substantially perpendicular to a main plane of extension of the mounting plate and in particular at least partially enclose the space in at least one direction, which could be oriented at least substantially parallel to a main plane of extension of the mounting plate. When viewing the base element in a direction which is in particular aligned perpendicularly to a main extension plane of the mounting plate, the base element could in particular have an oval shape, advantageously an elliptical shape and/or a circular shape. Preferably, the base member has a ring-like shape. In particular, the base element serves as a basis for arranging and/or fastening the fan blade elements. For example, the base element could be arranged on a side of the fan blade elements facing the mounting plate. Alternatively or additionally, the base element could be arranged, for example, on a side of the fan blade elements that faces away from the mounting plate. In this way, in particular, a structurally optimized base element can be provided.

In addition, it is proposed that the fan wheel be designed as a radial fan wheel and in particular be part of at least one radial fan, in particular the exhaust fan unit. This can in particular a high efficiency and / or a low noise development, especially in comparison to an axial fan, can be achieved.

Furthermore, it is proposed that the impeller has at least one passage opening, which allows liquid to pass from a suction side of the impeller to a pressure side of the impeller. In particular, the fan blade elements at least partially surround and/or delimit the passage opening of the fan wheel. The passage opening of the impeller is designed in particular as an impeller passage opening. The term "passage opening of the fan wheel" could be replaced by the term "fan wheel passage opening", for example. In particular, the passage opening of the impeller allows liquid to pass from a side of the impeller facing the mounting plate to a side of the impeller facing away from the mounting plate in at least one operating state. In at least one operating state, the suction side of the impeller is arranged in particular on a side of the impeller that faces the mounting plate. In at least one operating state, the pressure side of the impeller is arranged in particular on a side of the impeller facing away from the installation plate. The impeller has, in particular, a cylinder jacket-like shape. In this way, in particular, the shortest possible distance to be covered by the liquid to reach a fluid collection unit can be achieved, as a result of which in particular a low risk of soiling and/or damage to components of the hob can be achieved. In particular, an additional guide unit for guiding the liquid to the fluid collection unit can be dispensed with, as a result of which a cost-effective design can be achieved in particular.

In at least one operating state, the space is provided in particular for the passage of fluid, in particular from a side of the impeller facing the mounting plate to a side of the impeller facing away from the mounting plate. In particular, a proportion, in particular a volume proportion, of at least 60%, in particular at least 70%, advantageously at least 80%, particularly advantageously at least 85% and preferably at least 90% of the space is free of components, in particular the extractor fan unit and /or the hob. In this way, in particular, an optimized construction and/or undisturbed operation of the impeller can be made possible.

For example, the drive unit could, in particular in at least one operating state, be coupled to the impeller at an end region of the impeller facing the mounting plate. Preferably, the drive unit, in particular in at least one operating state, is coupled to the impeller at an end region of the impeller facing away from the mounting plate. As a result, the drive unit can be optimally positioned in particular. In particular, impairment of the drive unit, in particular by vapors sucked off by the impeller through the extraction recess, can be avoided.

In addition, it is proposed that the drive unit has at least one passage opening, which is provided for liquid to pass through. The passage opening of the drive unit is designed in particular as a drive unit passage opening. The term "passage opening of the drive unit" could be replaced by the term "drive unit passage opening", for example. In particular, the passage opening of the drive unit allows liquid to pass from a side of the drive unit facing the installation plate to a side of the drive unit facing away from the installation plate in at least one operating state. As a result, liquid penetrating through the trigger recess can pass through the drive unit, in particular the drive unit and the impeller, advantageously the extractor fan unit, in a structurally simple manner, whereby damage to the drive unit by the liquid can be avoided and/or a durable design can be achieved.

Furthermore, it is proposed that the through-opening of the impeller and the through-opening of the drive unit communicate with one another. In particular, the passage opening of the impeller and the passage opening of the drive unit are arranged in alignment at least in sections, in particular at least to a large extent and advantageously completely. The through-opening of the impeller and the through-opening of the drive unit are arranged overlapping at least in sections, in particular at least to a large extent and advantageously completely when viewed in a direction which is in particular aligned perpendicularly to a main extension plane of the mounting plate. As a result, in particular an unimpeded passage of liquid penetrating through the deduction recess into an area of the impeller and/or the Drive unit are made possible, whereby in particular an additional guide unit for guiding the liquid is dispensed with and/or low costs can/can be achieved.

For example, the drive unit could have at least one drive motor and at least one traction device, which in particular could couple the drive motor and the impeller to one another and in particular could at least partially surround and/or define the passage opening of the drive unit. The drive unit preferably has at least one drive motor, which has a ring-like shape and which has the passage opening of the drive unit. In particular, the drive motor at least partially encloses and/or defines and/or delimits the passage opening of the drive unit. In this way, in particular, a structurally optimized and/or compact design can be achieved.

In addition, it is proposed that the drive unit, in particular the drive motor of the drive unit, has at least one rotor and at least one stator, which each have a ring-like shape and are provided together to drive the impeller. In particular, the stator has at least a plurality of and preferably a large number of stator elements. In particular, the rotor has at least a plurality of and preferably a large number of rotor elements. A number of stator elements and a number of rotor elements are advantageously different from one another. The rotor elements and the stator elements are in particular arranged offset relative to one another. For example, the stator could have at least one electromagnet, in particular per stator element, and the rotor, in particular per rotor element, could have in particular at least one permanent magnet. For example, the rotor could have at least one electromagnet, in particular per rotor element, and the stator, in particular per stator element, could have in particular at least one permanent magnet. As a result, the impeller can be driven in a particularly reliable manner, as a result of which smooth operation and/or greater ease of use can be made possible.

Furthermore, it is proposed that the rotor and the base element are connected to one another in a fixed and/or non-rotatable manner, in particular in at least one operating state. In particular, the rotor and the base element, in particular in at least one operating state, are arranged in direct contact with one another at least in sections. The rotor and the base element could, for example, by means of at least be connected to one another in a non-positive manner and/or by means of at least one form-fitting connection and/or by means of at least one material-to-material connection. In this way, in particular, a high level of stability and/or an optimal coupling between the rotor and the base element can be provided, as a result of which, in particular, a high level of operating convenience can be made possible.

It is also proposed that the drive unit has at least one drive motor and at least one traction mechanism, which is provided in particular for being driven by the drive motor and which couples the drive motor and the impeller to one another. The drive unit is provided in particular to transmit at least one torque between at least two shafts, in particular between at least one shaft of the drive motor and at least one shaft of the impeller, at least by means of the traction means wrapping around the shafts. For example, the traction mechanism could couple the drive motor and the impeller to one another in a non-positive and/or positive manner. The drive unit could be provided, in particular by means of the traction means, for a non-positive and/or positive transmission of the torque between the shafts. The drive unit could, for example, have at least one chain drive and/or at least one toothed belt drive and/or at least one flat belt drive and/or at least one V-belt drive and/or at least one round belt drive and in particular be designed as such. In at least one operating state, the drive unit drives the impeller mechanically, in particular by means of the drive motor and the traction mechanism. As a result, the impeller can be driven in a structurally simple and/or simple manner, as a result of which, in particular, low costs and/or a reliable design can be achieved.

For example, the room could be completely devoid of cooktop and/or extractor fan unit components. The extraction fan unit preferably has at least one grease filter unit, in particular at least the grease filter unit, which is arranged at least in sections within the room. The grease filter unit protrudes at least into the space, in particular starting from a suction side of the impeller, in particular starting from the suction side of the impeller, and advantageously extends through the space. In particular, at least one section of the fat filter unit is on a suction side of the impeller, in particular on the suction side of the impeller, and at least one other section of the fat filter unit a pressure side of the impeller, in particular on the pressure side of the impeller. The section of the impeller and the further section of the impeller are connected to one another in particular by at least one section of the grease filter unit located within the space. As a result, fat particles dissolved in particular in the vapors produced in the operating state can be optimally filtered out, as a result of which a high standard of hygiene and/or greater ease of use can be achieved in particular.

When viewed perpendicularly onto a main extension plane of the mounting plate, the impeller and the extraction recess could be arranged at a distance from one another in the operating state, for example. For example, the exhaust fan unit could have, in particular in addition to the impeller, at least one further impeller which, when viewed perpendicularly to a main extension plane of the mounting plate, could be arranged in particular on a side of the exhaust recess facing away from the impeller. In the operating state, the impeller and the extraction recess are preferably arranged at least partially overlapping with one another when viewed perpendicularly to a main extension plane of the mounting plate. The exhaust fan unit has, in particular precisely, one, in particular a single, impeller. In particular, the impeller is arranged at least essentially and advantageously completely in the middle below the extraction recess. The expression that the impeller and the extraction recess in the operating state are arranged so that they "at least partially" overlap one another when viewed perpendicularly to a main extension plane of the mounting plate is to be understood in particular as meaning that at least a partial area of the impeller and at least a partial area of the extraction recess in the Operating state are arranged overlapping each other when viewed perpendicularly on a main extension plane of the mounting plate. For example, the impeller could have at least one further subregion, which in the operating state could be arranged at a distance from the vent recess and/or outside of a surface extension spanned by the vent recess when viewed perpendicularly to a main extension plane of the mounting plate. For example, the trigger recess could have at least one other subregion, which in the operating state when viewed perpendicularly to a main plane of extension Mounting plate could be arranged at a distance from the impeller and/or outside of a surface area spanned by the impeller. When viewed perpendicularly to a main extension plane of the mounting plate, the extraction recess in the operating state is in particular a proportion, in particular a surface proportion, of at least 50%, in particular at least 60%, advantageously at least 70%, particularly advantageously at least 80%, preferably of at least 90% and particularly preferably of at least 95% overlapping with the impeller and in particular within a surface area spanned by the impeller. In this way, in particular, a short distance to be covered by the sucked-off vapors produced in the operating state can be made possible, as a result of which a compact configuration can be achieved in particular. In particular, a complicated design of an additional guide unit for guiding the sucked-off vapors produced in the operating state can be dispensed with, as a result of which, in particular, a small number of components and/or a small stock can be achieved.

Furthermore, it is proposed that the extraction fan unit has at least one fluid collection unit, which is arranged on a side of the fan wheel facing away from the mounting plate. When viewed perpendicularly onto a main extension plane of the mounting plate, the fluid collection unit and the extraction recess are arranged in particular at least partially overlapping one another. A "fluid collection unit" is to be understood in particular as a unit which at least partially, in particular at least to a large extent and advantageously completely delimits and/or defines at least one fluid receiving space and which, in particular in the operating state, collects at least a large part of the fluid penetrating through the trigger recess and/or or records. For example, the fluid collection unit could have a cuboid shape. The fluid collection unit has, in particular, at least one fluid inlet, through which, in the operating state, in particular the fluid penetrating, in particular through the extraction recess, into at least one hob interior and/or located in at least one hob interior, enters, in particular into the fluid receiving space. In particular, the fluid collection unit has at least one fluid outlet, through which, in the operating state, in particular the fluid, in particular in the fluid receiving space, in particular from the Fluid receiving space, outlet. The fluid could, for example, contain vapors that occur in the operating state and/or be in the form of vapors that arise in the operating state. In particular, the fluid could be present in a gaseous and/or in a dissolved state and in particular in a gaseous and/or in a dissolved state could penetrate through the extraction recess of the mounting plate. The fluid could advantageously have at least one liquid exiting from at least one cooking utensil and in particular be embodied as at least one liquid exiting from at least one cooking utensil. The fluid is in particular in the form of a liquid and/or in particular has at least one liquid. In this way, in particular, a high standard of hygiene can be achieved and/or damage to components, in particular the hob, by penetrating fluid can be avoided, as a result of which a durable design can be achieved in particular.

In addition, it is proposed that the cooking system has at least one hob, in particular at least the hob, which has at least the exhaust fan unit. The hob is designed in particular as an induction hob, gas hob or radiant hob. In particular, in at least one operating state, the extractor fan unit is at least partially, in particular at least to a large extent and advantageously completely integrated in the hob, in particular in the outer housing unit of the hob. As a result, in particular, a separate extractor hood can be dispensed with, as a result of which, in particular, a small number of components and/or a small amount of stock can be achieved. By integrating the extractor fan unit in the cooktop, the extractor fan unit can be used in particular to cool components of the cooktop, such as a control unit and/or power electronics, which means that an additional cooling unit can be dispensed with in particular. In this way, in particular, a low noise level in the operating state and/or an inexpensive design can be achieved.

The cooking system should not be limited to the application and embodiment described above. In particular, the cooking system can have a number of individual elements, components and units that differs from the number specified here in order to fulfill a function described herein.
