Description

The present invention relates to a kitchen arrangement with hob and extractor device and to a method for operating a kitchen arrangement.

For cleaning of fumes and vapors that arise during cooking, it is known to use extractor devices that suck the vapors and fumes. In addition to extractor hoods, which are mounted above a hob, for example on a ceiling or room wall, there are also extractor devices that are mounted in or adjacent to the hob. These extractor devices are also referred to as table fans or tray ventilators. The extractor device in this case has an intake opening, which is offset either in the plane of the hob or in the vicinity of the plane of the hob to this up. In this type of extractor devices, the rising vapor is sucked in against the physical buoyancy downwards or sideways.

In order to ensure a reliable suction of fumes and fumes, which arise on the hob, the fan of the extractor device, which can also be referred to as a fan, must be operated at high power. In particular, high air velocities or intake rates are necessary. Due to the high performance and the resulting negative pressure, the distance between the place of origin of the Wrasens and the intake opening must be bridged. By operating the fan at high power level but it comes to increased noise. In addition, the air flow generated by the extractor device can be influenced by cross influences, such as an open window or the movement of the user of the hob and affect the reliable extraction of fumes and fumes.

To overcome these disadvantages, it is known to use supply air, which forms a kind of air curtain. For example, in the DE 10 2008 050 723 A1 a cooking device with purge air supply and purge air extraction described. This cooking device has two, three, four, five or more cooking zones, which is a hob unit form, wherein in each case between two cooking zones and / or in the outer lateral and / or rear and / or frontward edge portions of the hob unit one or more devices for the extraction of cooking fumes are provided in vertically downward direction and wherein in the or the device for the extraction of cooking fumes opposite, outer side and / or rear and / or frontwärtigen edge portions of the hob unit each one or more means for supplying air are provided as flushing medium.

A disadvantage of this cooking device is that it has a complex structure.

The object of the present invention is therefore to provide a solution with which, with a simple construction, vapor and vapor can be reliably sucked off.

The invention is based on the finding that this object can be achieved by supply air is output at least partially against the suction of the extractor device.

According to a first aspect, therefore, the invention relates to a kitchen arrangement comprising a hob with at least one cooking zone and a fume extractor comprising a fan and an extractor housing having a suction port for sucking air from the hob, the fan being displaced downwardly to the suction port is arranged and the suction port with at least one suction side adjacent to at least one cooking zone of the hob. The kitchen arrangement is characterized in that the extractor device comprises at least one supply air device with at least one dispensing element, in which at least one supply air opening is introduced, that the at least one dispensing element is located in the vicinity of the suction side of the intake and the output element at least temporarily to the supply air in Direction of the hob is aligned

The kitchen arrangement according to the invention comprises a hob and a fume extraction device. The cooking arrangement can be mounted in particular in a worktop, which for example represents the upper side of a kitchen base cabinet. The Hob includes at least one cooking zone. As a cooking zone, the area of the hob is referred to, in which a cooking vessel, such as a pot, which is placed on the hob, is heated by the hob. The cooking zones may in particular be defined by the heating elements integrated in the hob. For example, the cooktops can each be defined by a heating coil or an induction module. In an induction module, which extends over the entire hob, is referred to as the cooking zone, the region of the hob, in which actually takes place by the placement of the cooking vessel, a heating of the cooking vessel.

A cooking zone on which a cooking vessel stands and which heats this cooking vessel is referred to below as the active cooking zone.

The extractor device according to the present invention comprises a fan and a vapor extraction housing. The fan may be located in the extractor housing or in an associated housing or space. The fan, which may also be referred to as a fan, serves to generate a negative pressure through which air can be sucked into the extractor device and in particular the extractor housing. The extractor housing according to the invention comprises at least one suction opening for sucking air from the hob. The suction opening preferably has an elongated shape. As the suction port, the opening is referred to, is sucked into the air, which is sucked by the negative pressure generated by the blower, and thus enters the extractor device. The blower is according to the invention arranged offset to the suction down. This means that air is sucked down. The suction opening may be in the top of the extractor housing or in a side wall of the extractor housing. In the first case, the extractor device is also referred to as a trough blower and in the second case as a downdraft trigger. In a downdraft trigger the extractor housing extends over the plane of the hob or a mounting plane, in particular a worktop into which the hob is placed, up and out the suction is above the plane of the hob or mounting plane in the side facing the hob of the extractor housing.

The suction opening has at least one suction side. The suction side is the side through which air is sucked into the suction opening in a suction direction. The suction direction is directed in a vertical plan view of the hob on the suction port and is preferably perpendicular to the suction side of the suction port. The suction direction here refers to the main direction of the air flow, which is sucked into the intake.

The suction side of the suction port is adjacent to at least one cooking zone of the hob. In a fume extraction device, which is arranged so that the suction opening is behind the hob, the suction side of the suction port is therefore the front of the suction port. In a fume extraction device in which the suction opening is located in the center of the surface of the hob, the suction opening has two suction sides, which respectively represent the elongated side edges of the suction opening. One suction side is to the left of it lying cooking zones and the other suction side is adjacent to the right of it lying cooking zones. In a suction port, which is arranged laterally to the hob, the suction side is the side of the suction port, which faces the hob.

The suction direction, in which air enters the suction opening via the suction side, is in this case the direction which is directed from the adjacent cooking zone or zones to the suction side. The suction direction is therefore in a vertical plan view of the hob preferably perpendicular to the suction side, through which the air enters the suction port. In the case of a suction opening which, as described above, lies in the surface of the hob and thus has two suction sides, each of the suction sides thus has a different suction direction, which are opposite to one another.

Directional information, such as front, back, top and bottom refer - unless otherwise stated - to a kitchen arrangement and its parts in a state in which it is mounted in a horizontal mounting plane, such as a worktop. The front side refers to the side of the kitchen arrangement where the user usually stands. The back side refers to the side that usually faces a room wall. In addition, a right-handed coordinate system is introduced for better understanding. The x-axis and y-axis are horizontal and the z-axis is vertical. The x-axis lies in the direction between the Intake side of the suction port opposite side and the suction side of the suction port. Thus, in an elongated suction opening in which one of the longitudinal edges forms the suction side, the y-direction lies in the longitudinal direction of the suction opening and the x-axis extends perpendicular thereto in the horizontal to the hob adjacent to the suction side.

The kitchen arrangement is characterized in that the extractor device has at least one supply air device with at least one dispensing element in which at least one supply air opening is introduced, that the at least one dispensing element is located in the vicinity of the suction side of the intake and that the output element at least temporarily to supply air is aligned in the direction of the hob.

As a supply air device, a device is referred to, by means of which air can be moved to a supply air opening and can be output via this. The movement of the supply air can be done by a separate Zuluftgebläse. However, it is also within the scope of the invention that the supply air is moved by the blower of the extractor device, which generates the negative pressure for the intake of air. The supply air device may be arranged in a separate housing to the extractor housing. However, it is also within the scope of the invention that the supply air device is at least partially integrated in the extractor housing.

The supply air device according to the invention comprises at least one output element in which at least one supply air opening is introduced. The supply air opening is the opening through which the supply air is discharged from the supply air device. The supply air opening is at least temporarily arranged so that it is in the mounted state of the kitchen arrangement at a height above the mounting plate, in particular worktop in which the kitchen assembly is mounted and more preferably at a height which is above the hob. The dispensing element may, for example, be a tubular element or a channel element. The dispensing element can be designed in one piece with a supply air housing or the extractor housing. Preferably, however, the dispensing element is movably attached to the supply air housing or the extractor housing. The dispensing element preferably extends in the Vertical and the at least one supply air opening is introduced in a side wall or peripheral wall of the dispensing element.

The at least one dispensing element is located near the suction side of the suction port. In particular, in the case of an elongate suction opening, the dispensing element may be adjacent to one of the longitudinal ends of the suction side. Alternatively or additionally, at least one dispensing element lies outside the suction opening in front of a suction side. In these two embodiments, the dispensing element is thus located outside of the suction but adjacent to this. Furthermore, it is also possible that the dispensing element is arranged in the suction opening in the vicinity of the suction side.

The output element is according to the invention at least temporarily aligned for the output of supply air in the direction of the hob. As an output of supply air in the direction of the hob, in this case an output in one direction in the space above the surface of the hob is called. This room is also referred to below as a cooking space. Since the cooking vessel or cooking vessels are in this room during operation of the hob, and from these the air, in particular fumes and vapors, is sucked through the extractor device into the suction opening, the dispensing element is thus preferably at least temporarily aligned such that supply air is supplied via the supply air opening is discharged against the suction direction of the suction side of the suction port of the extractor device. The direction in which the supply air is output from the output element is also referred to as the output direction. As opposed to the suction direction is meant a Zuluftrichtung, wherein at least one component of the direction vector of the Zuluftrichtung in the space above the hob is opposite to a component of the direction vector of the suction. The dispensing direction is determined in particular by the position of the supply air opening. Therefore, preferably the supply air opening of the output element facing the space above the hob. For example, in one embodiment of the kitchen arrangement in which the suction opening is arranged behind the cooktop, the supply air opening may be introduced in the front side of the dispensing element or a front peripheral section of the dispensing element.

By the invention, an air supply device is provided, by means of which in the vicinity of the suction side of the suction opening of the extractor supply air can be output in the direction of the hob, the flow conditions can be influenced in the cooking chamber above the hob. In cooking operations resulting vapors and vapor, hereinafter referred to as vapors rise usually from the cooking vessel, such as a pot or a pan up, that is in the vertical direction. By inventively provided extractor device with suction, which is adjacent to at least one cooking zone, air is sucked from the cooking chamber in the direction of the suction and down. As a result, the flow direction of the resulting Wrasens is changed. This therefore no longer flows or no longer completely upwards but is deflected by the extractor device in an at least partially horizontal direction. This direction, which is also referred to as flow direction, is directed to the suction port. By the invention, an air supply device is provided through the supply air in the direction of the hob and thus at least partially distributed opposite to the direction of flow, air, which is located around this supply air, at least partially entrained. The entrainment of the surrounding air can be explained by the Venturi effect. This creates a certain negative pressure in the area around the supply air flow. By this negative pressure is vapor, which is already deflected by the extractor device from the vertically upward direction, further deflected. As a result, the direction of Wrasens is thus deflected downwards and thus in the direction of the suction port. The supply air flow thus supports the extraction of vapors and fumes from the cooking space. In addition, since the one or more output elements are in the vicinity of the suction, the structure of the kitchen arrangement is simplified because the supply air can be moved, for example, by the fan of the extractor device and thus neither an additional Zuluftgebläse nor a complex air duct is necessary.

According to a preferred embodiment, the at least one dispensing element is aligned so that the dispensing direction of the supply air is inclined in a vertical plan view of the surface of the hob to a vertical of the suction side in the horizontal. This means that the horizontal direction of delivery has both an x-component and a y-component of the coordinate system, each non-zero are. Thus, by not emitting the supply air exclusively in the x-direction, the output element (s) can be arranged at positions laterally of the suction opening, for example, at the lateral edges of the cooktop or extractor and still have the desired flow in the space above the cooktop produce. An arrangement of the dispensing element in the middle of the width of a suction opening, which extends in the width direction behind the hob, can thereby take place. Also in this embodiment, a pure forward output of supply air, without that this affects the space above a cooking zone, prevents and prevents direct flow of the user who is in front of the hob.

According to a preferred embodiment, the dispensing element is aligned so that between the suction side of the suction port and the output direction of the supply air in a vertical plan view of the surface of the hob is an angle of less than 90 °. If, for example, an output element is provided in each case in the vicinity of the longitudinal ends of the suction opening, the supply air openings are aligned such that they each output supply air in a direction which is directed from the outside to the center of the hob. If, on the other hand, one or more dispensing elements are provided in the center of the suction opening, then the feed air openings are aligned so that the respective supply air flow is directed from the center outwards.

According to a preferred embodiment, the at least one dispensing element extends above the plane of the hob upwards and the at least one supply air opening is located at a height which is close to the top of the hob. This makes it possible to output supply air along the surface of the hob. This supply air can reliably reach a cooking vessel, which stands on a cooking zone of the hob.

According to one embodiment, the supply air opening is oriented so that in side view of the hob, that is, in the direction of the y-direction of the coordinate system, the output direction of the supply air from the horizontal is inclined upwards. For example, the supply air can be inclined in a direction of 1 to 5 ° from the horizontal upwards be issued. As a result, friction losses, which can occur in the flow by flowing along the surface of the hob, can be prevented. However, the angle through which the supply air flow is inclined upwards is preferably so small that the supply air flow reliably reaches below the upper edge of a cooking vessel which stands on a cooking zone which is adjacent to the dispensing element. Thus, the sine of the angle between the horizontal and the supply air flow is preferably less than the quotient of the maximum height of a cooking vessel and the distance of an active cooking zone to the suction side of the suction port.

If the supply air is discharged too steeply, it can reach the vapor directly at the upper edge of the cooking vessel and therefore force it away from the suction opening.

According to a preferred embodiment, the at least one dispensing element is arranged offset to the suction opening. For example, an output element may be arranged adjacent to each longitudinal end of an elongated suction opening.

According to one embodiment, the supply air device has two supply air openings, which are arranged relative to one another such that the delivery directions of the two supply air openings in a vertical plan view of the hob are symmetrical to one another and different from each other. Since hobs usually have multiple cooking zones, this can be ensured in a simple manner a delivery of the supply air in the direction of the different cooking zones.

According to one embodiment, the supply air device may have at least one output element in which two supply air openings are introduced. The supply air openings are aligned in different directions. This form of dispensing element can be used, for example, in one embodiment of the extractor device, in which the dispensing element is arranged in the middle of the length of the suction opening. In addition, this embodiment of the output element can also be used in an embodiment in which the Suction opening is arranged centrally in the hob. In this embodiment, the Zuluftöffnungen are then introduced on opposite sides of the dispensing element, so that they can deliver supply air to lying on both sides of the suction cooking zones.

According to one embodiment, at least one dispensing element is at least temporarily oriented such that at least one supply air opening in the dispensing element is at least temporarily directed towards at least one active cooking zone. The active cooking zone is the zone on which there is a cooking vessel, which is heated by the cooking zone. By directing the air flow to the active cooking zone, it is ensured that the supply air reaches an area where the vapor is generated. The vapor is deflected by the extractor device from the vapor formation direction, which extends vertically upward, and directed to the suction port. Since the dispensing element is provided in the vicinity of the suction opening, it is ensured that with a supply air flow, which is directed to the active cooking zone, that the supply air flow and the deflected Wrasenstrom intersect in plan view of the hob. As a result, an influence of the Wrasenstroms can be ensured. In order to prevent damming of the supply air on the outside of the cooking vessel, which is on the active cooking zone and would lead to a shielding of the Wrasenstroms from the suction of the suction, in this embodiment, the speed or the pressure of the supply air is kept lower.

According to a preferred embodiment, at least one dispensing element is at least temporarily aligned such that at least one supply air opening in the dispensing element is at least temporarily directed tangentially to the at least one active cooking zone. Thus, the discharge direction of the supply air is at least temporarily directed tangentially to the at least one active cooking zone. By a tangential flow against the active cooking zone, on the one hand, a damming of the supply air to the cooking vessel can be prevented. On the other hand, it comes with tangential flow of the cooking vessel to form a Coanda effect on the outside of the cooking vessel. In particular, the supply air stream hugs the outside of the cooking vessel. As a result, even more air from the Sucked in the vicinity of the supply air flow and the influence of the Wrasenstroms reinforced in the direction of the intake.

According to one embodiment, the supply air opening is the opening of a nozzle. As a result, the supply air can be output at high speeds. According to an alternative embodiment, the inlet air opening constitutes a gap in the dispenser.

According to one embodiment, the suction opening is located in the surface of the hob. Here, in the surface of the hob, for example in the middle of the width, a recess is introduced, which extends in the depth direction of the hob. The extractor housing is arranged below the hob and the suction port is located in the recess of the hob. In this embodiment, preferably, the at least one dispensing element is also in the surface of the hob. However, it is also within the scope of the invention that the dispensing element is adjacent to the surface of the hob.

The at least one output element is preferably provided movably on the supply air device. In particular, the dispensing element can be made extendable. In particular, the dispensing element can be moved between a position in which the dispensing element lies below the mounting plane of the extractor device and the hob and a position in which it extends in regions above this mounting plane upwards. Thereby, the dispensing element in the state in which the extractor device is not operated, retracted and the supply air opening are thereby protected from contamination. When operating the extractor device, the output element can then be extended upwards.

According to one embodiment, the at least one dispensing element may additionally or alternatively be attached to the extendability rotatably attached to the supply air device. In particular, the output element is about a longitudinal axis in the vertical lies, rotatably mounted. As a result, different conditions on the hob can be taken into account. In particular, the orientation of the at least one supply air opening, which is provided on the output element, the position of a cooking vessel, which is located on a cooking zone of the hob, can be adjusted. Alignment adjustment can be manual or automatic.

According to a further aspect, the invention relates to a method for operating a kitchen arrangement. The kitchen arrangement here represents a kitchen arrangement according to the invention. In particular, the kitchen arrangement comprises a fume extraction device and a hob. The method is characterized in that during operation of the extractor device via at least one supply air supply air is output so that in at least one region of an active cooking zone of the hob vacuum is generated.

In particular, during operation of the fan of the extractor device, at least one air stream is discharged against the suction direction onto the suction opening in the region of the suction opening. The supply air is dispensed against the suction direction of the extractor device so that the suction direction is at least partially opposite to the output direction of the supply air.

Advantages and features that have been described with respect to the kitchen arrangement, apply as far as applicable to the inventive method and vice versa.

The supply air is preferably output so that the supply air flow flows along the outside of a cooking vessel along. This can be done in particular by tangential flow against the cooking vessel, which is on the active cooking zone. Particularly preferably, the supply air is discharged in a direction and a speed that the supply air conforms to the outside of the cooking vessel according to the Coanda effect.

According to a preferred embodiment, supply air having an operating pressure of a maximum of 1 bar is output via the at least one supply air opening. Of the Working pressure can be, for example, 0.1 bar. The supply air can be discharged at a speed of, for example, 14 m / s at the supply air opening at 0.5 bar. At a distance of 60mm to the supply air opening, the speed of 14.5m / s can be realized at 1 bar.

In the FIG. 1 a first embodiment of the kitchen arrangement 1 according to the invention is shown. The kitchen arrangement 1 comprises a fume extractor 2 and a hob 3. The hob 3 and the extractor device 2 are in a worktop P, which may for example represent the top of a kitchen cabinet introduced. The surface of the worktop P is also referred to below as the mounting plane.

The extractor device 2 is arranged behind the hob 3 in the illustrated embodiment. From the extractor device 2 is in FIG. 1 only to see the top of the extractor housing 20. In the extractor housing 20, a suction opening 200 is introduced, which is covered in the illustrated embodiment by a grid. The side of the suction opening 200, which faces the hob 3 and in particular is adjacent to at least one cooking zone 30 of the hob 3, is referred to as the suction side 2000 of the suction opening 200. The suction side 2000 is thus formed in the illustrated first embodiment of the kitchen assembly 1 through the front of the suction port 200. In the embodiment shown, the extractor device 20 also has two vapor shields 210, 211. The first vapor shield 210 has a smaller size than the second vapor shield 211. The vapor shields 210, 211 extend in the vertical direction in the embodiment shown. The first vapor shield 210 is disposed in front of the suction port 200 in parallel to the suction side 2000 of the suction port 200. The second vapor shield 211 is disposed behind the suction port 200 in parallel to the rear side of the suction port 200. The suction port 200 has, in the illustrated embodiment, an elongated shape extending in the width direction of the hob 3 behind this.

Furthermore, the kitchen arrangement 1 has an inlet air device 22. From the supply air device 22 are in FIG. 1 only output elements 220 can be seen. The supply air device 22 is in the first embodiment with the extractor device. 2 combined. In particular, the output elements 220 are introduced into the extractor housing 20 of the extractor device 2. The output members 220 are disposed adjacent to the suction port 200. In particular, the output members 220 are adjacent to the longitudinal ends of the suction port 200. The dispensing members 220 are tubular members that are closed at the top. At a portion of the peripheral wall of the output elements 220 each have a supply air opening 221 is introduced. The output elements 220 are aligned so that they can output air in the direction of the hob 3. The output elements 220 are preferably extendable.

The operation of the kitchen assembly 1 of the first embodiment will now be described with reference to FIGS FIGS. 2 to 5 described in more detail. In the FIG. 2 only one of the output elements 220 of the supply air device 22 is shown. If in the cooking vessel G, which is on a cooking zone 30 of the hob 3, cooked food or cooked, for example, water, so arises at this active cooking zone 20 in the cooking vessel G Wrasen, which rises upward. Through the supply air device 22 supply air is discharged in a discharge direction ZL, which is directed tangentially to the active cooking zone 20. As in FIG. 2 shown, is formed by the supply air flow around this, a negative pressure by turbulence, is sucked through the surrounding air. Also in the area of the cooking zone 20 surrounding air is entrained. As a result, the originally rising in the vertical direction Wrasen in the in FIG. 2 shown deflected direction WA drawn.

In FIG. 3 the state is shown in which in addition to the supply air device 22 and the extractor device 2 is operated. Air is sucked in the direction of the suction port 200 by the blower (not shown) that is downwardly displaced to the suction port 200. The main direction of this suction, which is referred to as suction direction A, is directed in a vertical plan view of the hob 3 perpendicular to the suction side 2000 of the suction port. Already by the suction through the extractor device 2, the vapor is deflected by the Wrasensentstehungsrichtung WE. In addition, in the FIG. 3 the supply air flow, which is output in the discharge direction ZL shown. Through this, the vapor is deflected further. The by the Vapor extraction device 2 and the supply air device 22 generated Wrasenabzugsrichtung WA is in the FIG. 3 shown schematically.

In the FIGS. 4 and 5 is the flow of supply air and Wrasens shown schematically in side view and in plan view. As is clear from the FIG. 4 results, the supply air from the output member 220 is output to the horizontal inclined upward. The angle between the horizontal and the discharge direction of the supply air ZL is preferably in the range of 1 to 2.5 °. Thus, the supply air reaches the cooking vessel G in a region between the bottom of the cooking vessel G, that is, the top of the hob 3 and the top of the cooking vessel G. The discharge direction of the supply air ZL is preferably aligned tangentially to the cooking vessel G. The vapor stream WA deflected by the supply air flow is in FIG. 4 also indicated. In the plan view, the in FIG. 5 is shown, it is clear that the - also deflected by the extractor device 2 - Wrasenstrom WA and the supply air flow ZL intersect.

In the FIGS. 6 to 9 Further embodiments of the kitchen arrangement 1 according to the invention are shown. In the FIG. 6 a second embodiment of the kitchen arrangement 1 is shown in plan view. As in the first embodiment, also in this second embodiment, the extractor device 2 and in particular the suction port 200 is arranged behind the hob 3. However, the second embodiment differs from the first embodiment in that the supply air device 22 comprises only one output element 220. This discharge element 220 is disposed in the middle of the width of the suction port 200. As shown, the dispensing element 220 may be in the suction opening 200 or, alternatively, in front of the suction opening 200. In this embodiment, two supply air openings (not shown), for example, can be introduced into the dispensing element 220, so that air can be dispensed via this dispensing element 220 in two dispensing directions of the supply air ZL, which can be directed to different cooking zones 32, 33 or 30, 31.

In the FIG. 7 a third embodiment is shown. In this embodiment, the extractor device 2 is arranged in the surface of the hob 3. In particular, lies the recess 200 and in a recess of the hob 3. The recess and thus the suction opening 200 extend in the depth direction of the hob 3 and are arranged in the width direction in the middle of the hob 3. The output elements 220 of the supply air device 22 are in this case provided in front of and behind the intake opening 200. These can be arranged in separate recesses of the hob 3. Alternatively, the housing of the extractor device 2 can also extend further in the depth direction of the hob 3 than the suction opening 200 and the output elements 220 can thus be arranged in the extractor housing. Each of the output elements 220 in this case has two supply air openings, can be output via the supply air in the delivery directions ZL and ZL '.

In this third embodiment, in which the suction opening 200 of the extractor device 2 is arranged in the surface of the hob 3, it has two suction sides 2000. The first suction side 2000 faces the hobs 31, 33 on the right side of the hob 3 and adjacent to them. Air is sucked in the suction direction A via this suction side 2000. The second suction side 2000 faces the hobs 30, 32. Through this suction side 2000, air is sucked in the suction direction A '. The suction direction A is in the negative x-direction of the coordinate system x, y, z and the suction A 'is in the negative x-direction of the coordinate system x', y ', z'. The output direction of the supply air

In the FIG. 8 a fourth embodiment of the kitchen arrangement 1 is shown. In this embodiment, the extractor device 2 has two suction openings 200 or two extractor devices 2 each having a suction opening 200 are provided. The suction openings 200 are in this embodiment not behind the hob 3 but laterally adjacent to this. In this case, the suction openings 200 extend in the depth direction of the hob 3. Moreover, in the fourth embodiment, four output members 220 are provided. These may belong to a single supply air device 22. Alternatively, however, two supply air devices 22 may be provided, each comprising two output elements 220. The output members 220 are respectively disposed in front of and behind the respective suction port 200. In this embodiment, the suction sides 2000 of the suction ports 200 are the sides that the hob 3 are facing. Thus, at the left suction port 200, the suction side 2000 is the right long side and at the right suction port 200 the left long side. In this embodiment, each cooking zone 30, 31, 32, 33 of the hob 3 may be associated with its own supply air flow ZL. The delivery directions of the supply air ZL are in the FIG. 8 indicated schematically.

The invention has a number of advantages. In particular, the extraction of fumes and vapor from the cooking chamber can be reliably ensured and at the same time the engine performance and thus the noise can be reduced. In the present invention, fumes and vapors are deflected so that they get targeted to the suction port of the extractor device. In the present invention, depending on the design of the extractor device, the Venturi effect and / or the Coanda effect is used. The Venturi effect entrains ambient air through the supply air jet. Due to the Coanda effect, the supply air flow, which flows along a cooking vessel, hugs this cooking vessel. In the present invention, the vapor can thus be at least partially deflected in the direction from which the supply air flow comes.

The delivery elements can be configured as additional nozzles, which are arranged in front of the actual extractor device and in particular in front of the intake opening. The dispensing elements are preferably arranged so that all cooking vessels and combinations of air flows can be detected. The discharge elements can be arranged laterally next to the suction opening and output air in the direction of the hob. The discharge elements can be supplied with additional fans or a branched air flow from the fan of the extractor device with the necessary air power. The output elements may be fixed or adjustable and / or extendable.

Preferably, the supply air flow is directed to a cooking vessel over in the middle of the hob.

With the present invention, a reliable suction can also be done by cooking zones, which are further spaced from the suction opening. In addition, the invention can be realized without that additional recesses or cutouts and installation spaces around the hob are necessary. This advantage is achieved by arranging the dispensing elements in the vicinity of the suction opening. The extractor device with supply air device can be used as a unit in a kitchen arrangement. As a result, the assembly and maintenance of the kitchen arrangement are simplified.
