[0004] There is a constant need to improve the operation of a cooktop extractor, or more generally, a kitchen appliance in the form of a cooktop and / or an extractor device. This object is achieved by the various aspects of the present invention.

[0005] The claims of the present application relate only to a selection of the (partial) aspects of the invention. This selection is not to be understood as limiting.

[0006] As will be immediately and clearly apparent to a person skilled in the art from the following general description and the description of exemplary embodiments, the invention comprises a plurality of at least partially independent (sub)aspects. These aspects, in particular the aspects of the invention highlighted below, can each lead to advantages on their own, i.e., independently of one another, or in combination with other sub-aspects. In particular, they can form the subject matter of claims, independent of other features.

[0007] Hereinafter referred to as optional features (" can " / " can ") are to be understood as such. They may be provided for, but do not necessarily have to be provided for.

[0008] The disclosure of an optional feature shall, in particular, include the disclosure of the corresponding complementary feature, even if this is not explicitly stated again in the description in the individual case. Specifically, this means: if the following states: "The device may have feature A ", it should be understood that the device does not necessarily have feature A, that is to say in particular that the device also has the feature "non-A " can have.

[0009] According to one aspect of the invention, the device for operating (hereinafter also operating device) a kitchen appliance, in particular a built-in kitchen appliance, in the form of a hob and / or an extractor device, in particular an extractor device for extracting cooking fumes downwards (downdraft extractor device), in particular a hob with an extractor device, is designed as a separate component.

[0010] This makes it possible to remove the control device from the hob and / or the extractor hood. The control device is therefore also referred to as removable, removable, or detachable. The control device can be removed without tools. The control device can be inserted into the kitchen appliance, in particular into an extractor hood, in particular into an inlet channel of an extractor hood, in particular into an inlet opening of an extractor hood, which can be arranged in a hob or next to a hob.

It can also serve as a closure element for closing the inlet opening, particularly in a further repositioned position, which is also referred to as the closure position.

[0012] The inlet opening is also called the inlet opening or cooking fume inlet opening.

[0013] The operating device can, particularly in an inflow position, only partially cover the inflow opening, in particular in such a way that cooking vapors can be extracted through the inflow opening. The cooking vapors can be extracted, in particular, through an area, in particular in the form of a gap, between the operating device and an edge of the inflow opening. In particular, one, two, three, or four such areas can be provided, in particular in the area of ​​the sides of the operating device.

[0014] In the inflow position, the control device can also rest on one, two, or three sides of an edge of the inflow opening. Two of the contact sides can be located on opposite sides, particularly in the area of ​​the front sides of the control device.

[0016] According to a further aspect, the operating device can be designed such that a locking side of the operating device in the locking position is at the level of the hob level, in particular is flush with it.

[0017] The closure side of the operating device can preferably have a surface whose appearance, in particular its color and / or structure, and / or its feel, is adapted to the surface of the kitchen appliance surrounding the inlet opening. The closure side can in particular be made of the same material as the surrounding surface of the kitchen appliance.

[0018] The operating device can be displaceable, in particular reversibly displaceable, in particular pivotable, between the inflow position and the closing position. For displacement between the inflow position and the closing position, the operating device can be pivoted about a pivot axis. The pivot axis can be horizontally aligned.

[0019] The relocation, in particular the pivoting, of the operating device can be carried out purely manually or purely motorically or with motor support.

[0020] Positioning means may be provided to support or ensure the precise adjustment of the inflow position and / or the closing position. Mechanical means, in particular detents, springs, stops, or a combination of such means, may serve as positioning means. Magnetic means, in particular one or more positioning magnets, may also serve as positioning means. Combinations of mechanical and magnetic positioning means are also possible.

[0021] The operating device can preferably be integrated into the surface of the kitchen appliance to operate it.

[0022] The removable control panel provides greater flexibility. This will be explained in more detail below.

[0023] The removability also makes cleaning the control unit particularly easy.

The housing of the operating device can, in particular, be designed according to IP 68.

[0034] The operating device, in particular its housing, can preferably be heat-resistant, in particular up to a temperature of at least 200°C, in particular at least 300°C. This can be achieved by appropriately selecting the materials used to manufacture the operating device.

[0035] The heat resistance provides protection against damage from hot cookware, for example. Due to its heat resistance, the control unit can also be used as a trivet.

[0036] Preferably, the housing cover is scratch-resistant. This makes the control unit particularly robust. The control unit can also be used as a cutting board.

[0037] In particular, electrical and / or electronic components, in particular one or more printed circuit boards, can be arranged in the housing. In the case of multiple printed circuit boards, these can be arranged side by side or stacked in the housing. They can also be arranged at an angle, in particular perpendicular to one another. Several printed circuit boards can be connected to one another by connecting elements in a signal and / or power-transmitting manner.

[0038] In particular, separate circuit boards can be provided for each hob. In a modular appliance with various possible modules, this makes it easier to adapt the control panel to the selected modules.

[0039] According to a further aspect, the operating device can have an input element in the form of a touch-sensitive sensor or screen for entering control data. Generally, the operating device can have one or more input elements. In addition to the aforementioned touch-sensitive elements, buttons, switches, or toggles can also serve as input elements.

[0047] Flexible connecting elements can be flex boards or ribbon cables. Flexible boards, also known as flex boards, are particularly robust, especially with regard to bending loads.

[0048] The interface may, in particular, have a multi-pole, in particular a four-pole contact, particularly in the form of a contact plug. The contact may be provided at the end of the flexible connecting element(s).

[0049] The use of such flexible connecting elements can be particularly advantageous for a pivotable arrangement of the operating device and / or a closure element for closing the inlet opening. The end of the flexible connecting element(s) facing the operating device can also be displaced, in particular when the operating device is displaced, in particular when it is pivoted.

[0050] In general, the kitchen appliance, in particular the extractor hood and / or the hob, in particular the control device of the kitchen appliance, can have a circuit board which is designed to be flexible, in particular a flexible circuit board. The circuit board can in particular be arranged such that it is displaced and / or deformed, in particular bent, during operation of the kitchen appliance. This makes it possible to design the kitchen appliance with components which can be displaced relative to one another and which are connected to one another in a signal- and / or energy-transmitting manner. The components can in particular be designed to be pivotable relative to one another. In particular, it can be provided to connect an operating device and / or a control device to other components of the kitchen appliance via a flexible circuit board.

[0130] The displacement can be carried out in particular in such a way that the insert is displaced, in particular shifted, into and out of the end position with a linear movement component. The insert can be pivoted between these linear displacements.

[0131] The displacement from the closed position to the inflow position can, in particular, follow the sequence: displacement – ​​pivoting – displacement. The two displacements can, in particular, occur in opposite directions or in directions that are oblique to one another, or in particular perpendicular to one another.

[0132] According to a further aspect of the invention, the insert and / or the operating device can be guided for displacement by means of at least one link device. This makes it possible to achieve multi-component displacement in a relatively simple manner.

[0133] The gate can, in particular, comprise a curved slot. A sliding block can be guided in the slot. The sliding block can also engage an opening in a force transmission lever. The opening can be designed as an elongated hole. At the opposite end of the lever, the lever can be connected to a rotary drive.

[0134] The sliding block can be permanently connected to the insert and / or the operating device.

[0135] The slotted gate can preferably be arranged in a fixed position relative to the cooking fume inlet device.

[0136] The slotted guide can be substantially quarter-circular or semicircular, or can have a circular arc section. The slotted guide can be tangentially extended at at least one end, in particular at both ends. The slotted guide can, in particular, have at least one straight section and one curved region, in particular in the shape of a circular arc section. The slotted guide can, in particular, have two straight sections and an intermediate region in the shape of a circular arc section.

[0137] Additionally, an additional slotted guide rail may be provided. This slotted guide rail may be fixed to the insert and / or operating device. It may, in particular, be linear. A sliding block fixedly connected to the cooking vapor inlet device may be guided in this slotted guide rail.

[0138] According to a further aspect of the invention, the actuating device for displacing the insert and / or the operating device has a rotary drive, in particular a purely rotary drive, in particular exclusively a single purely rotary drive. A motor, in particular an electric motor, serves as the drive. Multiple drive motors can also be provided. One or more actuators or servomotors can be provided as the drive. This enables a smooth movement sequence for displacing the closure element.

[0139] In general, a link guide can be provided in particular to specify the displacement trajectory of the insert and / or the operating device.

[0140] The guide rail may include one or more of the following elements: a link slot, in particular an angled or curved link slot, in particular a U-shaped link slot, a link block guided in the link slot, one or more levers, in particular one or more rotatably mounted levers, which in particular have a receptacle, in particular in the form of an elongated hole, in particular for guiding a link block. one or more gears which interact with a drive for displacing the insert and / or the operating device. The gear or gears can in particular interact with one or more of the levers. The gear or gears can in particular have a receptacle, in particular in the form of an elongated hole, in particular for guiding a link block.

[0141] The lever(s) can be connected to a drive device, in particular a motor, in a force-transmitting manner.

[0142] In general, one or two or more motors can be provided to relocate the insert and / or the operating device.

[0143] The motor(s) may be connected to the insert and / or the operating device via a gear mechanism, in particular with gears and / or shafts.

[0144] A single motor may be provided to move the insert and / or the operating device.

[0145] Two or more motors can also be provided for moving the insert and / or the operating device. The motors can be controlled independently of one another. The different components of the displacement can then be controlled independently of one another. This can lead to a less error-prone displacement. In particular, one motor can be provided for one or both of the linear displacements and one motor for pivoting the insert and / or the operating device.

[0146] One or more eccentrics can also be provided to move the insert and / or the operating device. For example, a first eccentric can be provided to convert a rotary drive component, in particular from a motor, into a linear component, in particular a lifting movement. The eccentric can be connected to the operating device and / or the insert via a carriage in a force-transmitting manner. A second motor can also be connected to the operating device and / or the insert via the carriage to pivot the operating device and / or the insert.

[0147] A further object of the invention is to improve an extractor device, in particular in the form of a so-called downdraft extractor.

[0148] This object is achieved by a fume extractor device with an inlet opening at least partially surrounded by a frame and an operating device that can be reversibly inserted into the inlet opening. When inserted into the inlet opening, the operating device can, in particular, reduce the maximum flow cross-section defined by the inlet opening.

[0149] The operating device can in particular be designed such that, when inserted into the inlet opening, it reduces the effective flow cross-section by at least 30%, in particular at least 50%, in particular at least 70%.

[0150] This allows the flow velocity in the area of ​​the remaining free flow cross-section to be increased. This can lead to better extraction of cooking fumes. The ratio of the visible surface of the operating device when inserted into the inlet opening to the maximum free flow cross-section defined by the inlet opening can be at least 30%, in particular at least 50%, in particular at least 70%.

[0151] The operating device can form a flow-influencing element, particularly when used.

[0152] Because it can be removed from the inlet opening, it can offer additional functions. This simplifies operation and enhances the cooking experience. The removable control panel makes it easier to clean.

[0153] When inserted into the inlet opening, the surface of the control device, in particular its screen, can be flush with the upper edge of the frame and / or a surface of a hob arranged adjacent to the inlet opening. This makes it possible, in particular, to integrate the control device flush into a hob system. When inserted into the inlet opening, in particular in the inlet position, the screen of the control device can be aligned, in particular, parallel to the hob plane.

[0154] When inserted into the inlet opening, an inlet slot, in particular a circumferential inlet slot, may remain, particularly laterally of the operating device, particularly between an edge of the operating device and the frame surrounding the inlet opening. Two slots may also be present, separated from each other by the operating device. The slots may extend, in particular, along the longitudinal sides of the operating device.

[0155] When inserted into the inlet opening, the operating device can also be completely circumferentially spaced from the flow channel. In this case, it can be surrounded by a circumferential slot. The extraction slot can, in particular, be designed to be simply continuous.

[0156] The shape of the frame, in particular its inner cross-section, can be adapted to the shape of the operating device, in particular its outer cross-section, in particular its housing.

[0157] The slots can, in particular, have a constant flow cross-section in the direction of flow. They can also have a flow cross-section that widens in the direction of flow. They can also have a flow cross-section that tapers in the direction of flow.

[0158] The frame can have rounded and / or beveled edges. This can improve, and in particular optimize, the flow-influencing properties of the frame.

[0159] A region of the flow channel, in particular a region of the flow channel adjoining the inflow opening, can be designed such that the operating device, in particular the insert, can be pivoted about a longitudinal axis.

[0160] The area of ​​the flow channel in which the operating device, in particular the insert with the operating device, is arranged during operation of the extractor device, in particular the area of ​​the flow channel in which the operating device, in particular the insert with the operating device, is pivotable, can have lateral widenings. This area can in particular have a cross-section shaped like a circular segment.

[0161] The flexible connecting element(s) for connecting the operating device can in particular be guided along a curved side wall of this section of the flow channel.

[0162] According to a further aspect, the region of the flow channel in which the operating device, in particular the insert with the operating device, is arranged during operation of the extractor device, in particular the region of the flow channel in which the operating device, in particular the insert with the operating device, is pivotable, can be designed such that a closure element for the inflow opening, in particular the operating device, can be completely displaced out of a flow region. In this case, the inflow opening can be completely open.

[0163] The flow region is understood here to be, in particular, a generally cylindrical region with the edge of the inlet opening as the guide curve. In the case of a partially concealed inlet opening, in particular an inlet opening with an outer edge and an inner edge, the flow region can be a hollow cylindrical region, in particular with an outer guide curve, which can in particular be rectangular, and an inner guide curve, which can in particular be rectangular. A generatrix of the cylindrical region can run obliquely or perpendicularly to the inlet opening, in particular obliquely or perpendicularly to the hob plane.

[0164] The closure element for the inlet opening, in particular the operating device, can be moved completely out of the flow area to the side, in particular below the hob level.

[0165] It may also be provided to form the closure element separately from the operating device. In this case, the closure element can be displaceable such that, when the operating device is in the inflow position, it is located completely outside the flow area.

[0166] According to one aspect, the closure element can be displaced, in particular pivoted and / or shifted, not only relative to the inlet opening but also relative to the operating device and / or the insert when displaced from the closing position.

[0167] According to an advantageous variant, the extraction slot(s) can be designed to be closable. To close the extraction slots, the extractor device and / or the operating device can have closure flaps. The inlet opening can also be completely covered, in particular closable, by the operating device. This can be achieved, for example, by inserting the operating device in a twisted position, in particular after rotation about its longitudinal axis. A separate closure element can also be provided to completely close the inlet opening.

[0168] Preferably, the extractor hood has a flat upper surface when the inlet opening is partially or completely covered or closed. This can be arranged flush with an adjacent hob.

[0169] According to a further aspect, the operating device can be arranged in a second arrangement on or in the extractor device in addition to a first arrangement in the inlet opening such that it, in particular its longitudinal axis, is aligned obliquely to a plane defined by the inlet opening.

[0170] This can lead to better visibility of the screen.

[0171] The inclined orientation is, in particular, a predetermined orientation. One or more inclined orientation positions can be predefined. The extractor hood device can, in particular, comprise one or more receiving elements and / or holding elements and / or a pivoting mechanism, by means of which the inclined orientation position(s) can be predefined.

[0172] The operating device can be oriented, in particular, around an adjustable viewing angle, in particular pivotable, in particular pivotable around one or two pivot axes.

[0173] This can particularly improve the use of the operating device as a multimedia device.

[0174] The operating device can also be pivotable within itself. It can, in particular, have one or more pivot axes. It can, in particular, have one or more hinged elements.

[0175] According to a further aspect, the extractor device, in particular the frame surrounding the inlet opening, can have one or more receiving elements for receiving, in particular for aligning and / or positioning, the operating device. The receiving elements can be formed on matching structures in the operating device, in particular on its housing.

[0176] The control unit can be mounted in the frame using a three-point support. This ensures a shake-free recording of the control unit in the frame.

[0177] The operating device, in particular its housing, and / or the frame surrounding the inlet opening, can have guide elements, such as webs, bevels, or guide rails. This can facilitate the insertion of the operating device into the inlet opening.

[0178] The operating device and / or the frame can, in particular, be designed such that the operating device is automatically guided into the correct position. The operating device is therefore also referred to as self-aligning.

[0179] One or more positioning magnets can be provided to guide and / or secure the control device in the frame. The positioning magnets can be arranged in the control device, in particular in or on its housing and / or in or on the frame. The magnets can ensure that the control device is automatically moved to a specified position. Several different positions for arranging the control device on the kitchen appliance can be provided.

[0180] The ability to insert or remove the control unit makes it interchangeable. This facilitates maintenance. It also makes it possible to provide different control units with different functionality, particularly with different functional scopes, for a specific extractor hood or hob system. For example, the simplest version of the control unit can only be used to operate the extractor hood and / or one or more hobs. Depending on the user's wishes or requirements, the control unit can assume more complex functions. For possible functions, please refer to the previous description.Depending on the customer's wishes, the extractor hood can be equipped with a minimalist control unit, a multimedia-capable control unit or a control unit that can be integrated into a home network.

[0181] For details of the operating system, please refer to the previous description.

[0182] The control unit can be used to operate the extractor hood and optionally also one or more hobs.

[0183] The extractor hood has one or more fans.

[0184] It can be a recirculation device, an exhaust air device, or an extractor hood device that enables both recirculation and exhaust air operation. In the latter case, it may be possible, in particular, to switch between recirculation and exhaust air operation using the operating device. In principle, such a selection can also be automated, in particular sensor-controlled. Likewise, switching between recirculation and exhaust air operation can also be prevented by sensors and / or external control signals. For example, exhaust air operation of the extractor hood device can be prevented if a fireplace is activated in the apartment. The latter can be detected by sensors. Exhaust air operation can also be prevented if the temperature difference between the outside and inside temperatures exceeds a predetermined value. This can generally contribute to energy savings.

[0185] According to a further aspect, the extractor device can have an odor filter module. The odor filter module can be removable. In particular, it can be connected to an inlet duct of the extractor device and / or to an exhaust opening of the fan housing.

[0186] The odor filter module has a filter seat. It may also have a filter change chamber. An odor filter can be reversibly arranged on the filter seat via the filter change chamber. The filter can be inserted into or removed from the filter change chamber, particularly through the cooking fume inlet.

[0187] The filter can be made up of one or more parts.

[0188] The filter may have a curved shape. This can facilitate insertion through the filter change chamber.

[0189] The filter can be designed to be reversibly deformable.

[0190] In particular, the filter change chamber allows tool-free access to an area downstream of the fan.

[0191] The filter change chamber can be designed to be closable, in particular hermetically sealed. It can be separated from an area upstream of the fan, in particular from a negative pressure area, by means of a flap. The closure element, in particular the flap, can be removed through the inlet opening of the downdraft extractor. It can separate a negative pressure area from a positive pressure area.

[0192] The filter change chamber can also be closed off from the removal opening by the filter itself. For this purpose, it may be sufficient for the filter to have a cross-section that essentially corresponds to the cross-section of the opening through which the filter is inserted into the filter change chamber, the removal opening.

[0193] In principle, a closure element for closing the opening to the filter change chamber can also be provided on the filter, in particular at one end thereof, in particular at one end in the longitudinal direction. The closure element on the filter can in particular be plate-shaped. It can preferably have a handle element by means of which the filter can be inserted into and removed from the filter change chamber.

[0194] One or more guide elements, such as guide rails, can be provided in the filter change chamber to guide the filter or filters when they are inserted into or through the filter change chamber.

[0195] The insertion and / or removal of the filter can be facilitated by aids such as springs, bearings, tabs or straps.

[0196] The filter seat can be located upstream of the fan. It can also be located downstream of the fan.

[0197] The aspects of the filter module are particularly advantageous independently of the other aspects of the present invention. They represent independent subject matter of the invention.

[0198] An object of the present invention is therefore also, in particular, an extractor hood device, in particular a modular extractor hood device, in particular for extracting cooking fumes downwards, with a filter change module.

[0199] Further advantages and details of the invention will become apparent from the description of exemplary embodiments with reference to the figures. They show: Fig. 1 schematically shows a view of a hob system with two hobs and a downdraft extractor arranged between them, Fig. 2 schematically shows a perspective view of a hob system with two hobs and a downdraft extractor arranged between them, Fig. 3 schematically shows an exploded view of a device for operating a hob system according to one of the Fig. 1 or 2 , Fig.4 schematically shows a perspective view of an extractor device for a modular hob system, in particular according to Fig. 2 , and Fig. 5 schematically shows a cross section through a further variant of a device for operating a hob system with an interface in the area.

[0200] In the following, the general components of a hob system 1 are described. The hob system 1 comprises at least one hob 2. In the Fig. 1The exemplary hob system 1 shown here includes two hobs 2. The hobs 2 can essentially be any type of hob. They can be, in particular, induction hobs, gas hobs, tepan yaki hobs, wok hobs, electric hobs or hotplates, grills, or other hobs. A hob is understood to mean, in particular, a device for heating food, particularly in the form of a built-in kitchen appliance.

[0201] At the Fig. 1In the alternative shown by way of example, control knobs 3 are provided for operating each of the hobs 2. Operation by means of touch-sensitive sensors, which can in particular be integrated into the hobs 2, is likewise possible. Operation via a separate control module is also conceivable. In this case, the hobs 2 can be designed to be non-autonomous, i.e. without their own control electronics. This can simplify the structure of the hobs 2. It is in particular possible to reduce the overall height of the hobs 2. It can in particular be no more than 10 cm, in particular no more than 6 cm, in particular no more than 5 cm, in particular no more than 4 cm, in particular no more than 3 cm, in particular no more than 2 cm.

[0202] A combination of different control elements is also possible. The hob system 1 can, in particular, comprise both control knobs 3 and one or more touch-sensitive input fields, in particular one or more touch-sensitive displays. Operation, in particular control of the hobs 2 and / or the extractor hood device described below, is possible, in particular, optionally via control knobs 3 and / or touch-sensitive input elements.

[0203] The hob system 1 further comprises a downdraft extractor 4. The downdraft extractor 4 forms a device for extracting cooking fumes. The term "downdraft extractor 4" refers in particular to the extraction device as a whole, and not just the actual fan.

[0204] The downdraft extractor 4, i.e., the extractor device, comprises one or more fans. The fans can, in particular, be designed as radial fans 21. However, this is not to be understood as a limitation. The radial fan(s) 21 can have one or more fan motors 22.

[0205] At the Fig. 2 In the alternative shown, the downdraft extractor 4 is arranged between the two hobs 2. It can also be arranged to the side of the hobs 2 or in the area behind the hobs 2.

[0206] It may have a round, in particular a circular, cooking vapor inlet opening 5. In the illustrated alternative, the cooking vapor inlet opening 5 is elongated, in particular rectangular.

[0207] The cooking vapor inlet opening 5 has, in particular, an aspect ratio of at least 2:1, in particular at least 3:1, in particular at least 5:1, in particular at least 10:1. Typically, the aspect ratio of the cooking vapor inlet opening 5 is at most 100:1, in particular at most 50:1.

[0208] Multiple cooking vapor inlet openings 5 ​​may also be provided. It is particularly possible to provide two or more cooking vapor inlet openings 5, in particular slot-shaped cooking vapor inlet openings 5. These can, in particular, be aligned parallel to one another.

[0209] The cooking vapor inlet opening 5 can be reversibly closed, in particular at least partially, in particular completely, by means of a closure element. It can be covered, in particular, at least in part, by means of a closure element. In the case of multiple cooking vapor inlet openings 5, these can each be reversibly closed separately, i.e., independently of one another, by means of closure elements.

[0210] A control knob 7 is provided for operating the downdraft extractor 4. Operation using a touch-sensitive sensor is also possible.

[0211] The downdraft extractor 4, in particular the cooking vapor inlet opening, is arranged in particular in the area of ​​a cooking surface level 8. It serves to extract cooking vapors from the area above the cooking surface level 8 to an area below the cooking surface level 8. It is therefore also referred to as a downdraft system (downward extraction).

[0212] The cooking fume inlet opening 5 is preferably arranged stationary relative to the cooking surface plane 8.

[0213] According to an alternative not shown in the figures, the area of ​​the downdraft extractor 4 with the cooking fume inlet opening 5 can be displaced in a direction perpendicular to the hob plane 8.

[0214] It can be provided to arrange the cooking vapor inlet opening 5 a few millimeters above the hob level 8. This can significantly reduce the risk of liquid accidentally entering the downdraft extractor 4, particularly in the event of liquids boiling over. In particular, it can also be provided to design the cooking vapor inlet opening 5 such that it can be moved to a position a few millimeters above the hob level when the downdraft extractor 4 is in operation. In this case, it can be arranged flush with the hob level 8 when the downdraft extractor 4 is switched off.

[0215] The hob system 1 is modular. In this case, essentially freely selectable hobs 2 can be flexibly combined with one or more of the downdraft extractors 4.

[0216] The hob system 1 can also be designed as an assembly unit. In this case, one or more hobs 2 are integrated with one or more downdraft extractors 4 into a single system. They are arranged in a common housing. For installation, this housing simply needs to be inserted into a recess in a worktop 9.

[0217] In the area below the hob system 1, compartments, in particular drawers 10 of a kitchen base unit 11, can be used essentially without restriction.

[0218] The kitchen base cabinet 11 generally forms a piece of kitchen furniture. The hob system 1, in particular the downdraft extractor 4, can be integrated into the kitchen furniture. They can, in particular, be integrated into the kitchen furniture at the factory.

[0219] The mounting unit, in particular the downdraft extractor 4, preferably has a total height h in the range of less than 30 cm, in particular less than 25 cm, in particular less than 20 cm, in particular less than 18 cm, in particular less than 16 cm, in particular less than 15 cm. In particular, the mounting unit does not require more space under the worktop 9 for installation than a normal cutlery drawer.

[0220] For corresponding details and further information on the general structure of the hob system 1, reference is made to EP 2 702 329 A1 and EP 3 475 622 B1, which are hereby fully incorporated into the present application as part of the latter.

[0221] Whenever the fans, motors or other components are referred to in the plural below, the generic plural, which includes the singular, is to be understood unless it is clear from the context that a plurality of corresponding elements is specifically required.

[0222] The fan motors 22 can be mounted or suspended. They can, in particular, be attached to a mounting frame 23. Such a mounting frame 23 enables particularly stable and reliable installation of the downdraft extractor 4, in particular its radial fan 21, particularly on the worktop 9.

[0223] The downdraft extractor has a shaft 24. The shaft 24 serves primarily as a collection space for the cooking fumes to be extracted. It can form part of a cooking fume inlet device.

[0224] A chamber 25 is located downstream of the shaft 24. The chamber 25 serves to convey the cooking vapors from the shaft 24 to the fan 21. Multiple shafts 24 may also be provided.

[0225] In particular, several chambers 25 may be provided.

[0226] In this case, several chambers 25 can be in flow connection, in particular, with a single shaft 24 or with several separate shafts 24.

[0227] The chambers 25 can form intake chambers of the radial fans 21.

[0228] The chambers 25 can be arranged at least in regions below the housing 26 of the radial fan 21 or the housing 26 of the radial fans 21.

[0229] The chambers 25 can also be arranged above the fan housing 26. This is particularly possible with double-flow fans.

[0230] The downdraft extractor 4 can have a filter seat 27 for receiving a filter. The filter seat 27 can, in particular, serve to receive an odor filter. The filter seat 27 can be arranged downstream of the fans 21 or upstream of the fans 21, in particular in the area between the cooking fume inlet opening 5 and the fans 21.

[0231] The filter seat 27 can be connected to the shaft 24 in particular via a filter change chamber 28.

[0232] The filter change chamber 28 and the filter seat 27 can form an optional module. They can be reversibly attached to the downdraft extractor 4, in particular to the shaft 24 and / or to the housing 26 of the radial fan 21. In the case of a pure exhaust air solution, the filter seat 27 and the filter change chamber 28 can be omitted. The filter change chamber 28 can be connected to the shaft 24, in particular via a reversibly closable or openable opening 45. The opening enables easy replacement of the filter, in particular an odor filter, and in particular its replacement and arrangement on the filter seat 27. The filter can be inserted and removed, in particular, through the cooking fume inlet opening 5. The opening 45 can preferably be reversibly closable. It can be closed, in particular, by means of a closure flap that can be reversibly removed through the cooking fume inlet opening 5.

[0233] Upstream of the shaft 24, in the area of ​​the cooking fume inlet opening 5, a frame element 29, which is also simply referred to as frame 29, is provided.

[0234] The frame element 29, in particular, completely surrounds the cooking vapor inlet opening 5. It can be a component of the shaft 24. The frame element 29 can, in particular, close off the shaft 24 on the inflow side.

[0235] The frame element 29 can have curved wall sections. The wall sections can, in particular, each be curved around horizontally extending axes. They can, in particular, be linear in the horizontal direction.

[0236] The frame element 29 can have a cross-section tapering in the inflow direction.

[0237] The frame may have a free edge 30, which is arranged in particular in the region of the hob plane 8. The free edge 30 may be very narrow. It may have a thickness, in particular a maximum thickness of at most 5 mm, in particular at most 3 mm, in particular at most 1 mm.

[0238] An operating device 31 can be inserted into the cooking vapor inlet opening 5. The operating device 31 can be inserted into the cooking vapor inlet opening 5 in a reversible manner. By inserting the operating device 31 into the cooking vapor inlet opening 5, the flow cross-section of the cooking vapor inlet opening 5, in particular the flow cross-section defined by the frame 29, can be reduced.

[0239] The operating device 31 can be inserted into the cooking vapor inlet opening 5 in such a way that its surface is flush with the surface of the adjacent cooking surfaces 2. The surface of the operating device 31 can, in particular, be flat.

[0240] The operating device 31 is described in more detail below.

[0241] The operating device 31 serves to operate, in particular to control, the hob system 1, in particular the hobs 2 and / or the downdraft extractor 4. The hob system 1, in particular the hobs 2 and / or the downdraft extractor 4, can also be operated, in particular controlled, via the control knobs 3, 7. However, the control knobs 3, 7 can also be omitted.

[0242] The operating device 31 has a housing 32. The housing 32 serves to accommodate electronic components.

[0243] The housing 32 has a housing base 33 and a cover 34.

[0244] The housing 32 can have flat longitudinal sides ( Fig. 5 ) or inwardly curved long sides ( Fig. 21 ).

[0245] By means of the cover 34, the housing lower part 33 can be covered, in particular closed, in particular sealed in a liquid-tight manner.

[0286] Alternatively, a contactless interface such as WLAN, NFC, Bluetooth or other can be provided.

[0287] In the Fig. 8 to 12 is a first drive concept for shifting the Fig. 6 and 7 shown insert 44 with the operating device 31.

[0288] In Fig. 8 Components of the first drive concept are shown.

[0289] The insert 44 is arranged in a shaft 24 with a curved section 53. The curved section 53 has a cross-section with two circular segments. The operating device 31 is in an assembled state, as shown in Fig. 9 , 10 , 11 and 13 shown, arranged in the bulge section 53.

[0290] In general, the shaft 24 and the arched section 53 are sections of an inflow channel.

[0291] A drive 54 is provided for displacing the operating device 31. The drive 54 comprises, in particular, an electric motor. The drive 54 is arranged on a first end face 63 of the shaft 24. A first gear 56 is arranged on the drive 54. The gear 56 is, as can be seen particularly well in Fig. 9 recognizable, with a second gear 60 and a third gear 61 in operative connection.

[0292] The second gear 60 is connected to a lever element 55 on a side facing the shaft 24. The third gear 61 is operatively connected to a drive rod 62. The drive rod 62 is rotatably mounted on the outside of the curved section 53. A fourth gear 65 is arranged on a second end face 64 opposite the first end face 63. The fourth gear 65 is operatively connected to a fifth gear 66, which in turn is operatively connected to a sixth gear 67. The sixth gear 67 is connected to a lever element 68.

[0293] The gears 56, 60 and 61 are arranged mirror-symmetrically to the gears 66, 67 and 65.

[0294] Via the gears 56, 60, 61, 65, 66, 67 and the drive rod 62, the drive 54 can simultaneously set the two lever elements 55, 68 into a rotary movement.

[0295] The lever element 55 is arranged on a first side in a recess 57 of a coupling plate 58. On a second side, the lever element 55 is arranged in an elongated hole 69 of the second gear 60. The lever element 55 is eccentrically set in a rotary motion by the second gear 60.

[0296] The coupling plate 58 is enlarged in Fig. 12 shown. The coupling plate 58 is arranged on the coupling section 52 of the holding frame element 46. The coupling plate 58 can be arranged on the holding frame element 46 in a material-locking, form-locking, and / or force-locking manner. Furthermore, the coupling plate 58 has a recess, in particular a guide groove 59, which interacts with a guide element (not shown) of the shaft 24 to guide the travel movement.

[0297] The lever element 68 is arranged on a first side in an elongated hole 71 of the sixth gear 67. On a second side, a pin 70 of the lever element 68 is arranged in a U-shaped groove 72 of a second coupling plate 73. The U-shaped groove 72 has a circular segment section and two linear sections. When the pin 70 moves in the linear sections of the U-shaped groove 72, the operating device 31 is linearly raised upwards or lowered downwards into the installed position. When the pin 70 moves in the circular segment section of the U-shaped groove 72, the operating device 31 is pivoted, in particular about a longitudinal axis, in particular about a horizontal longitudinal axis.

[0298] An exemplary hob system 1 with such a movement concept is shown in Fig. 13 shown.

[0299] The movement sequence of the operating device when moving from an inflow position to a closing position is as follows.

[0300] In Fig. 9 The operating device 31 is shown in an inflow position in which the inlet opening 5 of the extractor device 4 is exposed. The inlet opening 5 is also referred to as the inflow opening. The operating device 31 is in an activated position in which the input device 36 is accessible and the holding frame element 46 exposes a duct section for extracting cooking fumes. When the cooktop system 1 is switched off, the drive 54 is activated by actuating an actuating mechanism (not shown). The actuating mechanism can be a switch, control knob, touchscreen, or the control unit.

[0301] By activating the drive 54, the lever elements 55, 68 are set in motion. Due to the linear sections of the U-shaped groove 72 and the design of the lever element 55, the operating device 31 is first lowered linearly into the curved section 53 of the shaft 24. Subsequently, the operating device 31 is rotated by 90°. An intermediate position of this rotational movement is shown in Fig. 10 shown.

[0302] After rotating the operating device 31 by 90°, the operating device 31 is moved linearly upward through the linear section of the U-shaped groove 72. In this position, the cover 49 is aligned parallel to the upper edge of the shaft 24. In a stop position, also referred to as the closed position, the insert 44, in particular the cover 49, completely closes the cooking vapor inlet opening 5 of the shaft. The operating device 31 is arranged in the curved section 53 of the shaft 24. The cooktop system 1 is in the deactivated state.

[0303] The process described above is fully reversible. The operating device 31 can be rotated 90° in the opposite direction to release the cooking fume inlet.

[0304] To ensure that the input device 36 is still functional even after the operating device 31 has been rotated, the drive concept has a Fig. 8and 12 The flexible circuit board 97 shown in FIG. 1 is arranged on the coupling plate 58. It can deform with rotation of the operating device 31. The flexible circuit board 97 is, in particular, elastically and / or plastically deformable. Instead of a flexible circuit board 97, a flat cable can be selected. A flexible circuit board 97 is less susceptible to cable breakage than a flat cable.

[0305] In the Fig. 14 and 15A second drive concept is shown schematically. The drive concept has a U-shaped groove 74 that is fixed in position relative to the inlet channel. The U-shaped groove 74 has a circular segment section and two linear sections. It forms a guide slot. In the center of the circular segment section, a first lever 75 is rotatably mounted via a pin 76. The lever 75 can be driven via the pin 76 via a drive directly or indirectly via gears or a toothed belt.

[0306] The lever 75 also has an elongated hole 77. A pin 78 of a second lever 79 is arranged in the elongated hole 77. The pin 78 of the second lever 79 is guided in the U-shaped groove 74. The pin 78 forms a sliding block. The second lever 79 is connected in a rotationally fixed manner to the holding frame element 46 of the operating device 31.

[0307] By rotating the first lever 75, the pin 78 of the second lever 79 is guided in the U-shaped groove 74. In the linear section of the U-shaped groove 74, the operating device 31 is raised or lowered linearly. In the circular segment section, the operating device 31 is rotated by the rotationally fixed connection with the second lever 79.

[0308] The movement of the operating device 31 from an activated to a deactivated position and from a deactivated to an activated position proceeds as above. Fig. 8 to 13 described.

[0309] In Fig. 15 a hob system 1 with such a second drive concept is shown.

[0310] In the Fig. 16 to 20 A third drive concept is shown schematically. In Fig. 16 The individual components of the drive concept are shown in an exploded view.

[0311] The insert 44 includes the Fig. 6 and 7The holding frame element 46, which is explained in more detail, has the input device 36. Also shown are a shaft 24 with a curved section 53, two coupling plates 80, 81, two drives 82, 83, two drive belts 84, 85, a drive rod 86, two drive wheels 87, 88 and a guide plate 89.

[0312] The first drive 82 is arranged on the guide plate 89. The guide plate 89 is arranged to be linearly displaceable in a guide section 90 of the shaft 24. The drive 82 is connected in a rotationally fixed manner to a pin 91 of the coupling plate 80. The pin 91 is guided through a bore 92 of the guide plate 89. The coupling plate 80 is connected in a rotationally fixed manner to the coupling section 52 of the holding frame element 46. The holding frame element 46 can be set in a rotational movement by operation of the first drive 82. A rotated position is Fig. 18 shown.

[0313] The second drive 83 is connected in a rotationally fixed manner to the drive rod 86. The drive rod 86 is mounted in or on the housing of the shaft 24. The drive rod 86 has drive wheels 93 at each end. The drive wheels 93 are each operatively connected to a drive belt 84, 85. The drive belts 84, 85 are also operatively connected to the drive wheels 87, 88. Overall, the second drive 83 can rotate the first drive wheel 87 via the drive rod 86 and the drive belt 84, and the second drive wheel 88 via the drive rod 86 and the drive belt 85.

[0314] The drive wheels 87, 88 each have an eccentric pin 94, which is only visible on the drive wheel 88. The eccentric pin 94 of the drive wheel 87 is arranged in the horizontally extending slot 95 of the linear guide plate 89. Likewise, the eccentric pin 94 of the second drive wheel 88 is arranged in a horizontally extending slot (not shown) of a guide section 96 of the coupling plate 81. The guide section 96 is in Fig. 19 visible.

[0315] Upon rotation of the drive 83 and thus of the drive wheels 87, 88, the eccentric pin 94 is moved along a circular path. Only the vertical component of the circular motion is transmitted to the guide plate 89 and the guide section 96 through the elongated hole 95. The holding frame element 46 can be set into a linear motion by operating the second drive 82.

[0316] The position of the individual components in the assembled state is determined by Fig. 20 shown.

[0317] The motion sequence of the drive concept can be as follows. In Fig. 17 The insert 44 is shown in the inflow position. The operating device 31 is in an activated state. In the activated state, the cooking vapor inlet opening 5 is open and the input device 36 is accessible.

[0318] When the cooktop system 1 is switched off, the second drive 83 is activated first. The second drive 83 causes a linear movement of the holding frame element 46 downwards. After the linear movement has ended, the second drive 83 is deactivated and the first drive 82 is activated. The first drive 82 causes a rotational movement of the holding frame element 46. The rotational movement is preferably stopped by switching off the first drive 82 when the cover 49 is aligned horizontally. The second drive 83 is then activated. The second drive 83 can, in particular, rotate in the opposite direction to the first drive 82. The holding frame element 46 is thereby raised linearly until the cover 49 completely closes the cooking vapor inlet opening in the closed position.

[0319] When the hob system is activated, the process described above is carried out in reverse order, whereby the cooking fume inlet opening 5 is released and the input device 36 is moved into an accessible position.

[0320] The third drive concept is particularly advantageous because the linear movement and the rotational movement are completely decoupled and can be controlled individually as required.

[0321] The embodiments according to the Fig. 14 to 20 preferably also have a flexible circuit board 97 (not shown). The flexible circuit board ensures that the connection to the input device 36 is not interrupted.

[0322] In the Figures 22A and 22B a variant of the operating device 31 is shown by way of example and schematically, by means of which the inflow opening is in the first position (inflow position; Fig. 22A) partially releasable and in a second position (locking position; Fig. 22B ) can be closed.

[0323] The operating device 31 can be pivoted for this purpose.

[0324] The operating device 31 can be displaced in particular by pivoting through 180°, in particular about a horizontal axis between the inflow position and the closure position.

[0325] For further details of the operating device 31 and / or its pivotability, please refer to the previous description. In particular, the operating device 31 can also be part of an insert with one or more filter elements in this variant.
