When viewed perpendicular to the worktop, the fan wheels are located laterally to the side of the exhaust opening. The drive unit has two drive motors, one for each fan wheel.

For example, the exhaust fan unit could be designed to extract the vapors generated in the operating state from the cooking area and additionally from a cooking chamber, and, for example, to feed them into at least one exhaust duct. Alternatively, the exhaust fan unit could be designed, in particular, to transport the vapors generated in the operating state from the cooking area to at least another sub-area of ​​the cooking chamber.

[0016] In particular, the vapors generated in the operating state could be in a gaseous and / or dissolved state and, especially in a gaseous and / or dissolved state, could penetrate through the extraction recess of the mounting plate and / or enter at least one cooking surface interior.

[0017] The term "cooking area" shall be understood to mean, in particular, a section of a cooking chamber in which a cooking process takes place in at least one operating state and in which, in particular, fluids and / or vapors generated during the cooking process escape from a heated cooking vessel, and which, advantageously, extends at least to a large extent above the base plate and / or on a side of the base plate facing the operator. The term "cooking chamber" shall be understood to mean, in particular, a room in which a cooking system and / or a cooktop is arranged.

This allows for a particularly low noise level generated by the fan wheel during operation, which could be a maximum of 20 dB, particularly 18 dB, advantageously 16 dB, particularly advantageously 14 dB, and preferably 12 dB.

[0019] The term "drive unit" shall be understood to mean, in particular, a unit which includes at least one drive motor and, in particular, in at least one operating state, provides at least one driving force for a drive, in particular a mechanical drive, of the fan wheel, particularly by means of the drive motor. In particular, the drive unit, in particular by means of the drive motor, sets the fan wheel into at least one rotational motion. The drive unit, in particular the drive motor of the drive unit, is, in particular, in at least one operating state, connected to each other in a rotationally fixed manner and / or coupled to each other in a rotationally fixed manner.

[0020] In one installation position, the exhaust fan unit is arranged, in particular, below the mounting plate. The cooking system specifically comprises at least one outer housing unit, which is designed, in particular, as a cooktop outer housing unit and / or as a cooktop electronics housing unit and, advantageously, together with the mounting plate, defines a cooktop outer housing, at least substantially. For example, in one installation position, the exhaust fan unit could be arranged below the outer housing unit and, in particular, attached to at least one underside and / or at least one base of the outer housing unit. In one installation position, the exhaust fan unit could, in particular, be arranged, at least to a large extent, within the outer housing unit.The term "outer housing unit" shall be understood to mean, in particular, a unit which, in at least one assembled state, at least partially delimits and / or defines at least one receiving space, in particular a cavity, for receiving and / or storing at least one cooktop component. The cooktop component could, for example, include at least one heating unit and / or at least one control unit and / or at least one power supply unit and / or at least one user interface and / or at least one power supply electronics unit.

[0021] The phrase "at least partially" delimiting and / or defining a receiving space means, in particular, that the unit delimits and / or defines the receiving space alone or together with at least one other unit, such as the mounting plate. Specifically, the outer housing unit and the mounting plate together delimit the receiving space, at least substantially and advantageously completely.

Advantageously, the outer housing unit is designed as a one-piece and / or single-piece housing tray.The outer housing unit is designed in particular as a cooktop outer housing unit and advantageously as a cooktop electronics housing unit.

[0023] The outer housing unit has, in particular, at least one base which, in at least one operating state, defines and / or forms a side of the outer housing unit facing away from the operator. In at least one operating state, the distance between the base and the mounting plate, which is measured, in particular, perpendicular to the base and the mounting plate, is, for example, a maximum of 500 mm, more particularly a maximum of 400 mm, advantageously a maximum of 350 mm, particularly advantageously a maximum of 300 mm, preferably a maximum of 250 mm, and particularly preferably a maximum of 230 mm, thereby enabling, in particular, a compact design.

[0024] For example, the mounting plate and / or the cooktop comprising the mounting plate, particularly when viewed perpendicularly to a principal extension plane of the mounting plate, could have a maximum extension, in particular a width extension and / or a length extension, of a maximum of 100 cm, more particularly of a maximum of 90 cm, advantageously of a maximum of 80 cm, particularly advantageously of a maximum of 70 cm, preferably of a maximum of 65 cm, and most preferably of a maximum of 60 cm, which would allow even small cooktops to be equipped with an extractor fan unit. A "principal extension plane" of an object is understood to be, in particular, a plane that is parallel to a largest side face of the smallest imaginary geometric cuboid that just completely encloses the object, and in particular passes through the center of the cuboid.

[0025] The phrase "the extraction fan unit extracts at least some of the vapors generated in at least one operating state from at least one cooking area" is to be understood in particular as meaning that the extraction fan unit extracts vapors generated in the operating state from the cooking area, in particular through the extraction recess of the mounting plate, to a volume fraction and / or mass fraction, in particular of the total vapors generated in the operating state, of at least 20%, in particular of at least 40%, advantageously of at least 60%, particularly advantageously of at least 70%, preferably of at least 80% and particularly preferably of at least 90%.

[0026] The term "at least partially" enclosed by the fan wheel means, in particular, that the fan wheel encloses the space in at least one plane and, in particular, could partially enclose it in at least one further plane, especially exclusively. In the operating state, this plane could, for example, be aligned at least substantially parallel to a principal extension plane of the mounting plate. In the operating state, this plane could, for example, be aligned at least substantially perpendicular to a principal extension plane of the mounting plate.

[0027] The fan wheel encloses the space, particularly in at least one plane, which is preferably aligned at least substantially parallel to a main extension plane of the mounting plate, over an angular range of at least 90°, preferably at least 180°, advantageously at least 270°, particularly advantageously at least 300°, preferably at least 330°, and particularly preferably at least 350°. For example, the fan wheel could completely enclose the space and preferably have a cylindrical shape. Advantageously, the fan wheel partially encloses the space and preferably has a cylindrical shell shape. The space is particularly unbounded on one side of the fan wheel facing the mounting plate and / or on one side of the fan wheel facing away from the mounting plate, preferably by the fan wheel itself.

[0028] The term "essentially parallel" here refers in particular to an alignment of a direction relative to a reference direction, especially in a plane, wherein the direction has a deviation from the reference direction of, in particular, a maximum of 8°, advantageously a maximum of 5°, and most advantageously a maximum of 2°. The term "essentially perpendicular" here refers in particular to an alignment of a direction relative to a reference direction, wherein the direction and the reference direction, especially when considered in a plane, form an angle of 90°, and the angle has a maximum deviation of, in particular, a maximum of 8°, advantageously a maximum of 5°, and most advantageously a maximum of 2°.

[0029] The term "intended" should be understood to mean, in particular, specially designed and / or equipped. The fact that an object is intended for a specific function should be understood to mean, in particular, that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0030] According to the invention, the fan wheel has at least one base element from which at least a plurality of fan blade elements of the fan wheel project, which at least partially enclose and / or delimit the space. In particular, the fan wheel has at least a plurality of fan blade elements, advantageously at least the plurality of fan blade elements. A "plurality" shall be understood to mean, in particular, 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 plurality of fan blade elements. The fan blade elements are, in particular, aligned at least substantially parallel to one another.For example, the fan blade elements could be aligned at least substantially parallel to a principal extension plane 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 perpendicular to a principal extension plane of the mounting plate. Alternatively, the fan blade elements could be aligned obliquely relative to a principal extension plane of the mounting plate and, in particular, at least partially enclose the space in at least one direction, which could be oriented obliquely relative to a principal extension plane of the mounting plate.Advantageously, the fan blade elements could be oriented at least substantially perpendicular to a principal 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 principal plane of extension of the mounting plate. Considering the base element in a direction that is oriented, in particular, perpendicular to a principal plane of extension 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 element has a ring-like shape. In particular, the base element serves as a base for an arrangement and / or fastening of 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, for example, be arranged on one side of the fan blade elements facing away from the mounting plate. This allows for a structurally optimized base element.

[0031] Furthermore, it is proposed that the blower wheel be designed as a radial fan wheel and, in particular, be part of at least one radial fan, especially the exhaust fan unit. This allows for a high efficiency and / or low noise level, especially compared to an axial fan.

[0032] It is further proposed that the impeller have at least one opening that allows liquid to pass from a suction side of the impeller to a pressure side. In particular, the impeller blade elements at least partially surround and / or limit the opening of the impeller. The opening of the impeller is specifically designed as a blower impeller through-opening. The term "blower impeller through-opening" could, for example, be replaced by the term "blower impeller through-opening." In particular, the opening of the blower 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. The suction side of the impeller is, in at least one operating state, specifically located on a side of the impeller facing the mounting plate.The pressure side of the fan wheel is, in at least one operating state, located on the side of the fan wheel facing away from the mounting plate. The fan wheel has a cylindrical shape. This allows for the shortest possible path for the liquid to reach a fluid collection unit, thereby minimizing the risk of contamination and / or damage to cooktop components. In particular, an additional guide unit for directing the liquid to the fluid collection unit is unnecessary, resulting in a more cost-effective design.

[0033] The space is designed in at least one operating state to allow fluid to flow, in particular from one side of the fan wheel facing the mounting plate to one side of the fan wheel facing away from the mounting plate. Specifically, the space is free of components, in particular the exhaust fan unit and / or the cooktop, to a volume fraction of at least 60%, more particularly 70%, advantageously at least 80%, most advantageously at least 85%, and preferably at least 90%. This allows for an optimized design and / or uninterrupted operation of the fan wheel.

[0034] For example, the drive unit could be coupled to the fan wheel at an end facing the mounting plate, particularly in at least one operating state. Preferably, the drive unit is coupled to the fan wheel at an end facing away from the mounting plate, particularly in at least one operating state. This allows the drive unit to be positioned optimally. In particular, it prevents damage to the drive unit, especially from fumes drawn off the fan wheel through the exhaust opening.

[0035] Furthermore, it is proposed that the drive unit has at least one through-opening designed to allow the passage of liquid. The through-opening of the drive unit is specifically designed as a drive unit through-opening. The term "through-opening of the drive unit" could, for example, be replaced by the term "drive unit through-opening." In particular, the through-opening of the drive unit allows, in at least one operating state, the passage of liquid from a side of the drive unit facing the mounting plate to a side of the drive unit facing away from the mounting plate.This allows liquid penetrating through the exhaust recess to pass through the drive unit, in particular the drive unit and the blower wheel, advantageously the exhaust blower unit, in a structurally simple manner, thereby preventing damage to the drive unit by the liquid and / or achieving a durable design.

[0036] Furthermore, it is proposed that the opening of the blower wheel and the opening of the drive unit communicate with each other. In particular, the opening of the blower wheel and the opening of the drive unit are aligned at least partially, and preferably at least to a large extent, and advantageously completely. When viewed in a direction that is particularly perpendicular to a principal plane of extension of the mounting plate, the opening of the blower wheel and the opening of the drive unit are overlapping at least partially, preferably at least to a large extent, and advantageously completely.This allows, in particular, the unimpeded passage of liquid penetrating through the extraction recess into an area of ​​the blower wheel and / or the drive unit facing away from the mounting plate, thereby eliminating the need for an additional guide unit for guiding the liquid and / or resulting in lower costs.

[0037] For example, the drive unit could comprise at least one drive motor and at least one traction element, which could, in particular, couple the drive motor and the fan wheel and, in particular, at least partially surround and / or define the through-opening of the drive unit. Preferably, the drive unit comprises at least one drive motor which has a ring-like shape and which defines the through-opening of the drive unit. In particular, the drive motor at least partially surrounds, defines, and / or limits the through-opening of the drive unit. This allows, in particular, a structurally optimized and / or compact design to be achieved.

[0038] Furthermore, according to the invention, the drive unit, in particular the drive motor of the drive unit, comprises at least one rotor and at least one stator, each of which has a ring-like shape and is jointly provided to drive the fan wheel. In particular, the stator comprises at least a plurality and preferably a plurality of stator elements. The rotor comprises, in particular, at least a plurality and preferably a plurality of rotor elements. Advantageously, a number of stator elements and a number of rotor elements are different from one another. The rotor elements and the stator elements are arranged, in particular, offset from one another. For example, the stator could have, in particular, at least one electromagnet per stator element, and the rotor could have, in particular, at least one permanent magnet per rotor element.For example, the rotor, in particular each rotor element, could have at least one electromagnet, and the stator, in particular each stator element, could have at least one permanent magnet. This would allow the fan wheel to be driven in a particularly reliable manner, thereby enabling smooth operation and / or a high level of user comfort.

[0039] Furthermore, the rotor and the base element are rigidly and / or rotationally fixedly connected to one another, particularly in at least one operating state, according to the invention. In particular, the rotor and the base element are arranged in direct contact with one another, at least partially, particularly in at least one operating state. The rotor and the base element could, for example, be rigidly and / or rotationally fixedly connected to one another by means of at least one friction-fit connection and / or at least one positive-locking connection and / or at least one material-fit connection. This allows, in particular, high stability and / or optimal coupling between the rotor and the base element to be provided, thereby enabling, in particular, a high level of user-friendliness.

[0040] In a non-inventive embodiment, the drive unit comprises at least one drive motor and at least one traction element, which is particularly designed for drive by the drive motor and which couples the drive motor and the fan wheel. The drive unit is particularly designed 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 fan wheel, at least by means of the traction element encircling the shafts. For example, the traction element could couple the drive motor and the fan wheel by friction and / or positive locking. The drive unit could, in particular by means of the traction element, be designed for a frictional and / or positive locking transmission of the torque between the shafts.The drive unit could, for example, include 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 mechanically drives the blower wheel, in particular by means of the drive motor and the traction element. This allows for a drive of the blower wheel in a structurally simple and / or straightforward manner, thereby achieving low costs and / or a reliable design.

[0041] The space could, for example, be completely free of components of the cooktop and / or the extractor fan unit. Preferably, the extractor fan unit has at least one grease filter unit, in particular at least the grease filter unit, which is arranged at least partially within the space. The grease filter unit projects, in particular from a suction side of the fan wheel, at least into the space and advantageously extends through the space. In particular, at least one section of the grease filter unit is arranged on a suction side of the fan wheel, in particular on the suction side of the fan wheel, and at least one further section of the grease filter unit is arranged on a pressure side of the fan wheel, in particular on the pressure side of the fan wheel.The fan wheel section and the subsequent section of the fan wheel are connected to each other, in particular by at least one section of the grease filter unit located within the space. This allows for optimal filtration of grease particles dissolved in the vapors generated during operation, thereby achieving a high standard of hygiene and / or ease of use.

[0042] When viewed perpendicularly to a main plane of the mounting plate, the fan wheel and the exhaust opening could, for example, be spaced apart from each other in the operating state. For example, the exhaust fan unit could, in particular, in addition to the fan wheel, have at least one further fan wheel, which, when viewed perpendicularly to a main plane of the mounting plate, could be arranged, in particular, on a side of the exhaust opening facing away from the fan wheel. Preferably, the fan wheel and the exhaust opening are arranged to overlap at least partially in the operating state when viewed perpendicularly to a main plane of the mounting plate. The exhaust fan unit has, in particular, exactly one, and in particular a single, fan wheel. In particular, the fan wheel is arranged at least substantially and advantageously completely centrally below the exhaust opening.The phrase "that the fan wheel and the exhaust opening are arranged to overlap at least partially" in the operating state when viewed perpendicularly to a main extension plane of the mounting plate" means, in particular, that at least a portion of the fan wheel and at least a portion of the exhaust opening are arranged to overlap in the operating state when viewed perpendicularly to a main extension plane of the mounting plate. For example, the fan wheel could have at least one further portion which, in the operating state when viewed perpendicularly to a main extension plane of the mounting plate, could be spaced apart from the exhaust opening and / or located outside the area defined by the exhaust opening.For example, the exhaust recess could have at least one further section which, when viewed perpendicularly to a main plane of the mounting plate, could be spaced apart from the fan wheel and / or located outside an area defined by the fan wheel when viewed perpendicularly to a main plane of the mounting plate. When viewed perpendicularly to a main plane of the mounting plate, the exhaust recess, in the operating state, is particularly overlapping with the fan wheel to a proportion, and especially an area, of at least 50%, more particularly at least 60%, advantageously at least 70%, particularly advantageously at least 80%, preferably at least 90%, and particularly preferably at least 95%, and is located within an area defined by the fan wheel.This allows for a short distance between the extracted vapors generated during operation and the resulting compact design. In particular, a complex additional guide unit for directing the extracted vapors generated during operation can be avoided, resulting in a reduced number of components and / or lower inventory requirements.

[0043] Furthermore, it is proposed that the exhaust fan unit comprises at least one fluid collection unit, which is arranged on the side of the fan wheel facing away from the mounting plate. When viewed perpendicularly to a principal plane of extension of the mounting plate, the fluid collection unit and the exhaust opening are arranged to overlap, at least partially. A "fluid collection unit" is understood to be, in particular, a unit that at least partially, and preferably at least to a large extent and advantageously completely, delimits and / or defines a fluid receiving chamber, and which, particularly during operation, collects and / or receives at least a large portion of the fluid entering through the exhaust opening. 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, the fluid, especially that which penetrates and / or is located in at least one cooktop interior through the extraction recess, enters the fluid collection chamber. The fluid collection unit also has, in particular, at least one fluid outlet through which, in the operating state, the fluid, especially that which is located in the fluid collection chamber, exits the fluid collection chamber. The fluid could, for example, contain vapors generated in the operating state and / or be in the form of vapors generated in the operating state. In particular, the fluid could be in a gaseous and / or dissolved state and, especially in a gaseous and / or dissolved state, penetrate the extraction recess of the mounting plate.The fluid could advantageously include at least one liquid emanating from at least one cooking vessel and, in particular, be designed as at least one liquid emanating from at least one cooking vessel. The fluid is specifically designed as a liquid and / or, in particular, includes at least one liquid. This allows, in particular, a high standard of hygiene to be achieved and / or prevents damage to components, especially the cooktop, from penetrating fluid, thereby enabling, in particular, a durable design.

[0044] Furthermore, it is proposed that the cooking system comprises at least one cooking zone, in particular at least the cooking zone which includes at least the extraction fan unit. The cooking zone is specifically designed as an induction cooking zone. The extraction fan unit is, in particular, at least partially, in particular at least to a large extent, and advantageously completely integrated into the cooking zone, especially into the outer housing unit of the cooking zone, in at least one operating state. This eliminates the need for a separate extractor hood, thereby resulting in a reduced number of components and / or lower inventory requirements.By integrating the extraction fan unit into the cooktop, it can be used to cool cooktop components such as the control unit and / or power electronics, thus eliminating the need for a separate cooling unit. This results in a low noise level during operation and / or a more cost-effective design.

[0045] The cooking system is not intended to be limited to the application and embodiment described above. In particular, the cooking system may, to fulfill a function described herein, have a different number of individual elements, components, and units than specified herein.
