In the case of a driven actuation, the displacement of the at least one cooking product carrier can take place without the force of the user. For example, the displacement device can be actuated by a user input on the operating unit or on the basis of a signal of a sensor.

The displacement device can in particular be actuated automatically. For this purpose it can be coupled to a control device for controlling the energy transmitter. In particular, it is possible to control the displacement device in such a way that it moves the at least one cooking product carrier from a rest position into an operating position when at least one of the energy transmitters is put into operation. Preferably, after decommissioning all of the energy transmitters, in particular after elapse of a predetermined waiting time, they can automatically return the cookware carrier to the rest position.

Alternatively, the at least one cookware carrier may also comprise a pot carrier of a gas hob. According to one alternative, the at least one cooking utensil carrier comprises a cooking product receptacle of a Teppan Yaki cooking area. The at least one cooking utensil carrier may also include a grill grate. Preferably, the at least one cooking product carrier is tuned to the energy transmission principle of the at least one energy transmitter. The cooktop device is a kitchen built-in appliance. The cooktop device is designed for attachment to the worktop, in particular to the worktop of a kitchen cabinet. In particular, it can be integrated into the worktop, in particular in such a way that its surface is flush with the surface of the worktop.

The at least one energy transmitter can be an electrical energy transmitter, in particular an induction cooking station or a heat radiating cooking area or a Teppan-Yaki cooking area or a chemical energy transmitter, in particular a gas hob, in particular an e-gas hob , or a barbecue, act. Combinations of these alternatives are possible. The hob can be used as a glass-ceramic hob, as an induction hob, as a Teppan-Yaki hob, as a gas hob, especially as an electric gas hob, as a grill, as a fryer or as a sous vide hob or as a be designed other hob or as a combination of these alternatives. Preferably, the hob comprises a plurality of cooking zones with, in particular, different energy carriers, which are equipped with a common food carrier. The at least one cooking utensil carrier can also be composed of different types of cooking utensils. To connect the displacement device with the composite cooking product carrier, the carrier fastening means of the displacement device may comprise a carrier frame. Preferably, the hob comprises at least two, at least three, at least four energy carriers. It may also have more than four, in particular five, six or more energy carriers.

Control unit buttons, especially knobs and / or push buttons and / or removable control knob on. The removable control knob may have different functionalities depending on its relative position to the control unit. The operating unit may be a touch-sensitive TFT display, in particular a TFT touch display. This allows a particularly comfortable control of the hob and / or the displacement device. The operating unit can be in signal connection with a control device. The control device can be designed to control consumers, in particular of the at least one energy transmitter and / or the displacement device and / or the extraction device. The at least one cooking utensil carrier can be connected to a receiving frame for receiving the at least one energy transmitter, in particular glued. In particular, it can be connected directly to the at least one energy transmitter, in particular adhesively bonded.

The at least one cooking product carrier can also be sealed relative to the receiving frame and / or the at least one energy transmitter by means of a sealing element and not be glued to it.

Preferably, the hob, in particular the at least one cooking utensils, from above can be removed. The assembly of the hob, especially the at least one cooking product carrier and / or their cleaning can be facilitated. Preferably, the hob is designed such that it can withstand vertical loads of at least 100 N, in particular at least 200 N, in particular at least 500 N, in particular at least 1000 N. Preferably, only materials, in particular plastics, metals and glasses are used for the hob device, which up to a temperature of at least 110 ° C, in particular at least 150 ° C, in particular at least 200 ° C, in particular at least 300 ° C, in particular at least 350 ° C are heat resistant. The at least one cooking product carrier may be rectangular, in particular non-square or square, or round, in particular non-circular or circular, in particular oval, in a plan view.

According to a further aspect of the invention, the at least one energy transmitter is firmly connected to the at least one cooking product carrier. Advantageously, it is thereby achieved that both the at least one cooking product carrier and the at least one energy transmitter are fastened displaceably to the worktop by means of the displacement device. For example, the entire hob can be moved by means of the displacement device relative to the worktop. Since the at least one cooking utensil carrier thus maintains its relative position relative to the at least one energy transmitter, it can be designed to transmit the energy from the at least one energy transmitter to the cooking product in a simple and efficient manner. The functionality of the hob for heating food is thus always given regardless of the position of the at least one cooking product carrier. Also, the operating unit and / or the control device for controlling the at least one

Energieüberträgers can be attached to the at least one cooking product carrier. Movable connection lines can thus be limited to energy transmission lines.

According to a further aspect of the invention, the displacement device has a locking means for locking the at least one cooking product carrier in at least one discrete locking position. Advantageously, it is achieved that the at least one cooking product carrier is securely held in the at least one locking position. The effect of forces on the mini- At least one cooking utensil carrier during cooking or by moving pots or cooking good thus cause no unwanted displacement of at least one cooking product carrier. The locking of the at least one cooking product carrier in the at least one locking position can by positive engagement, in particular a tongue and groove connection and / or a toggle lever and / or a bolt and / or a resilient thrust piece, or by adhesion, in particular a clamping connection, and / or a magnetic connection can be achieved. The locking means may be arranged between the worktop and the at least one cooking product carrier. The locking means can enable an energetically stable position of the at least one cooking product carrier. On the basis of the weight of the at least one cooking product carrier and / or on the basis of a force applied by a spring element spring force, thereby at least one locking position of the at least one cooking utensil carrier can be defined. Alternatively, the at least one cooking product carrier can be locked by means of the displacement device continuously at any locking positions. The detection can take place at all positions, which can be achieved by the freedom of movement granted by the displacement device. For this purpose, the locking means is preferably designed as a clamping connection.

In particular, with a driven displaceability of the cooking product carrier, a stepless lockability can be provided. The stepless lock can be achieved in particular via the drive mechanism for shifting the cooking product carrier. According to a further aspect of the invention, the at least one cooking utensil carrier has a surface which, in at least one of the fixing positions, terminates flush with the worktop at least in sections. Preferably, the at least one cooking product carrier has a surface which, in each displacement position, terminates at least in sections, in particular completely, flush with the surface of the worktop. Advantageously, this is achieved by the cooktop device interacting in an aesthetic manner with the worktop. Pots could also be particularly due to the edgeless arrangement simply be moved between the worktop and the at least one cooking utensils.

To determine the at least one cooking utensil carrier, the worktop may be formed with an at least partially encircling groove or cutout, which supports the flush arrangement of the at least one cooking utensil carrier relative to the worktop. Alternatively or additionally, at least one locking position for at least partially flush arrangement of the at least one cooking product carrier can be formed on a mounting frame of the hob device.

According to a further aspect of the invention, the displacement device for guided displacement of the at least one cooking product carrier on a guide means. The guide means allows a simple and secure way the displacement of the at least one cooking product carrier according to a predefined displacement movement.

The guide means may be, for example, a slotted guide. The at least one cooking utensil carrier can be connected via the carrier fastening means with a sliding block. This engages positively in a slot of a link plate. The slide plate is connected to the worktop via the plate fastener. The displacement of the at least one cooking product carrier is performed and according to the configuration of the slot of the guide slot.

The sliding guide can be designed to guide the at least one cooking utensil carrier in a U-shaped path. For this purpose, the slot can be designed as a U-shaped recess in the slide plate, in particular with a horizontal section and two vertical, downwardly directed sections. The sliding block and the slot can have a clearance fit for the low-friction guidance of the at least one cooking product carrier.

Alternatively, the guide means may be a bearing, in particular a linear bearing, in particular a ball bearing or a roller bearing or a plain bearing. For example, the at least one cooking product carrier can be displaceable along a bearing rail. The guide means may also be a telescopic pole or a telescopic rail. In an advantageous embodiment, the guide means comprises a lever mechanism with one or more levers, which are also referred to below as a lever system. The lever system may for example be a parallelogram. The parallelogram guide allows a displacement of the at least one cooking product carrier relative to the worktop along a circular path, without tilting the at least one cooking product carrier about a horizontal axis.

Preferably, a cooking surface plane defined by the surface of the cooking product carrier remains parallel to the horizontal plane during the displacement of the cooking product carrier. This is also referred to as horizontal displacement of the cooking product carrier.

According to one aspect of the invention, the cooking surface plane defined by the surface of the cooking product carrier remains in one and the same plane during the entire displacement of the cooking product carrier, ie is not displaced in the direction perpendicular to this plane. If the displacement is a linear displacement, this is also called horizontal displacement. If the displacement is a rotational displacement, this is called a horizontal rotation. According to one aspect of the invention, the displacement of the at least one cooking product carrier can take place at least partially unaffected. The displacement device can be designed for partially guiding the displacement, in particular for guiding in an exclusively vertical direction, or merely for providing discrete bearing positions of the at least one cooking product carrier. In this case, the displacement device does not necessarily actively contribute to the displacement of the cooking product carrier.

According to one aspect of the invention, the displacement device can be designed as a detachable connection means, in particular in the form of a non-positive connection or in the form of a positive connection, in particular as a spring bolt connection. The detachable connecting means may be arranged in an edge region of the at least one cooking product carrier. The displacement device may for example comprise a bolt which is connected via the carrier-fastening means with the at least one cooking product carrier, as well as a provided with U-shaped recesses plate which is connected via the plate-fastening means with the worktop. The bolts fastened to the at least one cooking utensil carrier can be hooked into various of the U-shaped recesses in order to displace the at least one cooking utensil carrier.

According to a further aspect of the invention, the guide means is adapted to allow a displacement with a movement component parallel to the cooking surface plane.

The displacement can have a lateral movement component in the form of a lateral movement, as viewed by the user of the hob. Alternatively, the displacement of the at least one cooking utensil may have a component of movement transverse to the back of the hob, in the form of a transverse movement, i. have a movement towards or away from the user of the hob. The motion component of the at least one cooking product carrier which is parallel to the cooking plane can be achieved by a linear and / or a rotary bearing, in particular around a vertical axis.

The guide means can be designed to mount the at least one cooking product carrier about a vertical axis. The storage around the vertical axis is preferably carried out in combination with a cooking product carrier which is round, in particular circular, in cross-section. The at least one cooking utensil carrier can also be rotatably mounted relative to the worktop about any other axis. The guide means may also be designed to displace the at least one cooking product carrier by means of a combined linear and rotational movement with respect to the worktop.

According to a further aspect of the invention, the guide means for displacing the at least one cooking utensil carrier is formed between at least two locking positions, these locking positions in the direction perpendicular to the cooking surface maximum 50 mm, in particular a maximum of 30 mm, in particular a maximum of 20 mm, in particular a maximum of 10 mm , are spaced from each other. By limiting the distance between the at least two locking positions with respect to the transverse direction to the cooking surface plane is achieved advantageously that the potential energy to be overcome in the displacement of the at least one cooking product carrier is limited. The relocation of the at least one cooking product carrier is thus particularly simple and energy-efficient. According to an advantageous alternative, the displacement of the at least one cooking product carrier can be carried out exclusively parallel to the cooking surface level.

According to a further aspect of the invention, the cooktop device may have a balancing device for covering a gap between the at least one cooked product carrier and the worktop. The surface of the compensation device can be formed in at least one locking position of the at least one cooking product carrier flush with the cooking surface and / or the worktop. The compensating device may be designed for displacing the at least one cooking utensil carrier removable or pivotable and / or lowerable.

The compensating element may be designed to effect actuation of the at least one energy transmitter and / or the extraction device and / or the displacement device when actuated. The control device is preferably designed to control the at least one energy transmitter and / or the extraction device and / or the displacement device on the basis of a signal of a sensor of the compensation device. Alternatively, the actuation of the at least one energy transmitter and / or the extraction device and / or the displacement device can be purely mechanical. For example, the at least one cooking utensil carrier can be displaced upon actuation of the compensating device and / or the hob can be switched on, in particular supplied with power.

According to a further aspect of the invention, the locking means for limiting the guided displacement of the at least one cooking utensil carrier at least one end stop. The at least one end stop may be formed, for example, by the at least two ends of the slot of the slide guide.

If the displacement device is designed as a linear bearing, then the end stop can be designed as a stop element clamped on the guide rail. The at least one end stop may have an elastic and / or damping element. A jerky braking of the at least one cooking product carrier at the end stop can thus be avoided.

The locking means may have an end stop at each of the at least two locking positions.

According to a further aspect of the invention, the displacement device for displacing the at least one cooking product carrier has a drive device. The drive device enables the particularly simple displacement of the at least one cooking product carrier relative to the worktop.

The drive device may be passive or active.

The passive drive device is actuated purely by force of the user.

The active drive device can assist or completely effect the displacement of the at least one cooking product carrier. The active drive device has this for a power supply.

The drive device may be arranged between the at least one cooking product carrier and the worktop and provides a force and / or moment between these components.

The passive drive device can store, for example, an energy introduced by the user into the displacement device and, if necessary, release it again for displacement of the at least one cooking product carrier. For example, a locking mechanism upon actuation of the user, in particular by pressing on the surface of the at least one cooking utensil, the stored energy release. In the case of an active drive, an external energy source can be used to provide the energy needed to displace the at least one food carrier.

According to a further aspect of the invention, the drive device comprises a spring element. The spring element can be used for passive support of the displacement of the at least one

Cookware carrier be formed. Preferably, the spring element between the at least one cooking product carrier and the worktop is arranged.

The spring element is for example a spiral spring, in particular a compression spring or a tension spring, or a torsion spring or a gas spring or an elastic element made of a flexible material. The spring element can be arranged in such a way between the at least one cooking product carrier and the worktop that it is stretched in a closed position of the hob and is relaxed in the displacement of the at least one cooking utensil in an open position of the hob.

The spring element can be arranged to overcome the weight of the hob at this. Alternatively, the weight of the hob can be compensated by a counterweight. The displacement of the at least one cooking product carrier in the vertical direction can thus be particularly simple.

The spring element can also be designed to form stable layers of the at least one cooking product carrier. For example, the spring element can be arranged in a toggle mechanism such that the at least one cooking product carrier is locked in a locking position when a knee point of the toggle mechanism is exceeded.

According to a further aspect of the invention, the drive device comprises an electric motor. As a result, the displacement of the at least one cooking product carrier can take place actively and without the action of force by the user. The electric motor may have a transmission for power conversion, in particular a planetary gear or a cam gear. Preferably, the electric motor is designed as a servomotor. The electric motor may be a DC or AC motor. In an advantageous embodiment variant is the electric motor as a linear cylinder, in particular with spindle gear formed. The electric motor can partially support or completely effect the displacement of the at least one cooking product carrier. The operating unit may be designed to enable the control of the electric motor via a user input. Alternatively, the control of the electric motor by the control device, for example on the basis of a sensor signal, take place. For example, the at least one cooking product carrier can be displaced by activation of at least one energy transmitter by means of the electric motor.

The drive device can also have a pneumatic or hydraulic drive.

According to a further aspect of the invention, the cooktop device has a sealing element for sealing the at least one cooking utensil carrier relative to the worktop. The seal may be liquid-tight and / or gas-tight. The penetration of dirt or overflowing cooking material between the at least one cooking product carrier and the worktop can thus be reliably prevented.

The sealing element may be a static or a dynamic seal. The static seal can be used to seal between two immovable components. The dynamic seal can also be used for sealing between two mutually movable borrowed components.

The sealing element may be arranged on the at least one cooking product carrier and / or on the worktop. Alternatively, the sealing element can also be arranged on a mounting frame for mounting the hob device. A sufficient sealing effect can be achieved in that the sealing element covers a gap between the worktop and the at least one cooking product carrier and / or that the sealing element is formed overlapping with respect to the at least one cooking product carrier and / or the worktop. The sealing element may be an inflatable seal. The cooktop device can for this purpose have a pressure generator for providing the pressure for the inflatable seal. The sealing element may be designed to seal the at least one cooking product carrier relative to the worktop only in the closed position and / or the open position. According to a further aspect of the invention, the cooktop device has a take-off device for the withdrawal of cooking fumes from below. The extraction device can be integrated in the hob. The cooktop device with the hob, the displacement device and the extraction device can be designed as an assembly unit.

According to a further aspect of the invention, the extraction device has an inlet opening which is completely concealed in a locking position of the at least one cooking product carrier. Due to the design of the cooktop device as an assembly unit, the at least one cooktop carrier can be displaced particularly precisely with respect to the inlet opening of the extraction device by means of the displacing device. The seal between the at least one cooking product carrier and the inlet opening can thus be done effectively and reliably.

The extraction device can in particular be arranged completely below the cooking surface level.

The at least one inlet opening can, in particular in at least one of the locking positions, in particular in the open position, be arranged in a plan view in an edge region of the hob, in particular of the at least one cooking product carrier. The at least one inlet opening may be formed in the plan view as a straight, in particular rectangular slot. Preferably, the at least one inlet opening in the plan view does not extend completely along an outline of the at least one cooking product carrier. The inlet opening has in particular a size which is at most as large, in particular smaller than the surface of the cooking product carrier. It preferably has a length which is at most as large, in particular smaller than the width of the cooking product carrier. Even the inlet opening can also have several subregions. In this case, the above information refers to the union of the subareas.

The at least one inlet opening can be arranged in plan view exclusively in the region of a single edge of, in particular rectangular, at least one cooking product carrier. The inlet opening adjoins in plan view in particular only to a single edge of the cooking product carrier. By this is understood that the edge in a closed Position to this edge of the cooking product carrier has a distance of less than 5 cm, in particular less than 3 cm. The distance to the other edges of the cooking product carrier is larger. Preferably, the at least one inlet opening is arranged on a rear side of the at least one cooking product carrier.

The at least one inlet opening may be delimited at least on one side in the plan view by the at least one cooking product carrier. Preferably, the at least one inlet opening in the plan view is completely bounded by a withdrawal channel.

A main extension of the inlet opening is preferably at most as large as a main extension of the hob, in particular of the cooking product carrier. Under the main extension of the inlet is hereby understood their largest free width or their length. This main extension is in particular at most as large, in particular smaller than an extension of the hob, in particular of the cooking product carrier, in a direction parallel thereto.

The extraction device can in particular be stationary, d. H. be arranged not displaced. Alternatively, it is possible to move a cooking fume inlet region of the trigger device after release of the cooking fume inlet opening by a corresponding displacement of the cooking product in the vertical direction. The inlet region of the extraction device can preferably be displaced in such a way that the cooking vapor inlet opening terminates substantially flush with the surface of the cooking product carrier in the open position, which is not covered by the cooking product carrier. This can improve the efficiency of the extraction device.

The invention is further based on the object to provide an improved hob system.

This object is achieved by a cooktop system with at least one hob device and a fume extraction device. The at least one cooktop device is in particular displaceable relative to the withdrawal device, in particular relative to a vapor inlet opening of the withdrawal device.

The hob system may in particular comprise two or more than two cooktop devices, in particular more than three, in particular more than four, in particular more than five, in particular more than six, in particular more than ten, cooktop devices. The hob devices can be displaced independently of one another, in particular displaceable. In particular, they may be displaceable, in particular displaceable, independently of one another relative to a vapor inlet opening of the trigger device.

The at least one cooktop device can be controlled by the user via a single operating unit. This control unit can be mounted on a cooktop device or on the worktop. Alternatively, several control units on different cooktop devices may be in signal communication with each other. Thus, the control of the entire cooktop system can take place via each of the several operating units.

Two or more cooktop devices may have a common displacement device for displacement relative to the tabletop. For example, the cooking utensils of the plurality of cooktop devices may be arranged on a common guide means via their carrier fastening means. In particular, the guide means may comprise a guide rail on which the plurality of cooking utensils are mounted and can be moved laterally.

According to one aspect of the invention, an inlet opening of the extraction device can be arranged below the at least one cooking product carrier. By moving the at least one

Cooking product carrier, the inlet opening, in particular between the more than two cooking utensils, depending on the position of the at least one cooking product carrier released or hidden, in particular completely hidden, in particular sealed, are. Preferably, the extraction device comprises the inlet opening, the outlet channel, a fan and an outlet opening. The extraction device can be arranged completely below the hob area level. Preferably, a withdrawal channel of the withdrawal device is for at least partially horizontal guiding the cooking fumes formed. The fan of the trigger device can be controlled via the at least one control unit. The control of the fan can be done by a user input or coupled to the operating state of the at least one cooktop device. Alternatively, the extraction device may have a sensor that determines the extraction demand, wherein the performance of the fan is controlled according to this deduction requirement.

According to one aspect of the invention, the trigger device is activated by means of the control device upon activation of the at least one energy transmitter. The displacement device can move the at least one cooking product carrier upon activation of the trigger device in a position in which the at least one entry device is not covered.

The inlet opening of the extraction device can be rectangular, in particular square or non-square, or round, in particular circular or non-circular, in particular oval, in a plan view. Preferably, the inlet opening is completely concealed by the at least one cooking utensil carrier of the at least one cooktop device.

The inlet opening of the extraction device may have a plurality of partial openings. These partial openings can also be connected to separate exhaust ducts. The inlet opening may also have an inlet aperture with baffles for guiding the extractor flow.

In principle, a component of the extraction device can also be displaced in the vertical direction. For details refer to the previous description. According to a further aspect of the invention, the at least one cookware carrier at least partially conceals the inlet opening in at least one covering position. In this way, it can be advantageously achieved that the withdrawal flow can be influenced in accordance with the position of the at least one cooking product carrier.

According to a further aspect of the invention, the extraction device may have separate closure elements. With the help of the separate closure elements, it is possible to open and close the inlet opening of the extraction device in certain areas. In particular, a separately displaceable closure element can be provided for each of the cooking zones. As a result, the efficiency of the take-off device can be improved. In particular, it is possible to increase the speed of the withdrawal stream in the region of the inlet opening, in particular without an increase in the performance of the fan motor of the withdrawal device being necessary for this purpose.

The inlet opening can also be completely covered by the at least one cooking product carrier in at least one covering position, in particular completely closed, in particular sealed. The closure of the inlet opening by the at least one cooking utensil carrier may be in particular liquid-tight, in particular airtight. The sealing element can be designed to form a gas-tight seal of the inlet opening, for example between the at least one cooking product carrier and the edge of the worktop and / or between the at least one cooking product carrier and the edge of the inlet opening. Complete obstruction of the inlet opening when the extraction device is not used can prevent the ingress of soiling into the extraction device.

According to one aspect of the invention, the at least one cooking product carrier is positioned flush with the worktop in at least one locking position. This results in a particularly aesthetic appearance of the hob system, for example in the closed position.
