The hob can be designed as an induction or electric hob, preferably, the at least one hob is a gas hob or a grill. In a gas hob, the at least one heating element is a gas burner. In a grill, in particular a grill intended for installation in a worktop of a kitchen environment, the at least one heating element is designed as a gas burner or as a resistance heating element.

The extractor device is designed to discharge vapors to below the plane of the decorative plate of the hob and / or to below the plane of the aperture of the extractor device. Decorative panel and panel are preferably arranged in a common plane.

According to one embodiment variant, the hob and the extractor device are arranged adjacent to one another, in particular integrated in a worktop of a kitchen environment.

Decorative panel and panel can rest as elements on a worktop of a kitchen environment or in this, in particular flush-mounted, be embedded. Specifically encompassed by the invention is the possibility that decorative panel and panel are executed by the worktop of a kitchen environment. Then, the recess is formed in the worktop and arranged the at least one heating element below the surface of the worktop.

Under a worktop, a plate can be understood, as can also be used for preparing food or storage of cookware.

According to a particular embodiment, extractor device and hob are designed as a common device. This manifests itself in the form of a common control and / or a shared enclosure and / or shared Fastening means for installation in a worktop of a kitchen environment and / or the one-piece design of decor panel and panel.

The extractor device may for example comprise a fan for generating an air flow through which air can be drawn into the recess. The recess may be connected via a channel with the fan. In the flow direction of the Wrasens a filter shaft is provided to / behind the recess. The filter shaft serves to accommodate at least one grease filter. In one embodiment, the filter well is part of the channel between the recess and the fan. Preferably, the filter shaft and thus the grease filter below the plane of the decorative plate of the hob and / or the plane of the aperture of the extractor device is arranged.

For example, the lid can be designed to be placed on a narrow or long side on a located between the hob and the recess mounting portion of the panel and / or decorative plate and / or worktop.

According to an advantageous embodiment, at least one lid magnet element and / or at least one positioning magnet element are arranged in the lid at least one cover magnet element and / or under the installation section of the panel, decorative element or worktop. These enable the lid to be magnetically fixed to the panel, decorative element or worktop in a state set up on the set-up section.

The arrangement may comprise one or more detection devices. These can be part of the extractor and / or the hob.

The detection device for detecting the position of the lid is preferably arranged in the region of the recess such that the closed lid and the partially opened lid can be detected. This makes it possible to turn on the fan only when the degree of opening has exceeded a minimum. This prevents an inflowing air draft makes it difficult to remove the lid.

A partially open lid closes with the panel, the decorative element or the worktop an angle in the range of 0 degrees to 25 degrees, preferably an angle in the range of 0 degrees to 12 degrees.

A detection device for detecting at least one position of the lid is for example designed, arranged and aligned such that the removal of the lid from the recess can be distinguished from a partial opening. The partial opening can be done with or without the assistance of a lifting device.

A lifting device acts on the lid without being coupled to the lid. For this purpose, the lid is loosely on a lifting device designed as a lifting pin. Another embodiment of the lifting device provides that the lifting device consists of an electromagnet which acts in opposite polarity to a magnet in the lid when the electromagnet against the magnet in the lid and thus lifts the lid from the rest position.

The lid can be erected between the recess and a heating element on the Aufstellabschnitt. This allows the lid to act as a partition between hob and recess. If the hob is a gas hob, it can prevent the gas flame from being drawn into the cavity. In an embodiment of the hob as a grill, even an electric grill, flames can occur when, for example, dripping oil or grease on a heating element.

A detection device for detecting at least one position of the lid is, for example, designed, arranged and aligned such that the setting up of the lid on the set-up section can be detected. As a result, the security of the arrangement can be improved, for example, in which the hob is activated only when the lid is positioned on the Aufstellabschnitt.

A further embodiment of this detection device is designed, arranged and aligned such that the orientation of the lid erected on the positioning section can be detected. This makes it possible to control the arrangement depending on which side of the lid faces the hob. Preferably, in particular in a hob designed as a gas hob or grill, this is the side which has a greater temperature resistance. In addition, the detection device can be integrated in the footprint and / or the lid. As a result, the position of the lid can be reliably detected.

Depending on the embodiment, the detection device can be realized as an optical, capacitive, inductive, piezoelectric or magnetic sensor. This allows precise detection of the position.

The controller may be configured to deactivate the hob when the lid is not positioned between the recess and the hob, or to activate the hob when the lid is positioned between the recess and the hob. This allows the hob to be switched on or off automatically. Thus, a switching of the household appliance depending on the handling of the cover realized by the cover done. For example, an electronic circuit of a valve for the gas supply of a gas burner and a control of the hob can be done about it.

For example, the hob may be disabled if the lid is not installed when used in addition to a gas hob or grill. Or it can be done automatically when the lid is set up. Turning on the hob is understood here to mean that the hob has been set to operational readiness. This may include opening a safety valve for the gas supply as well as moving the hob to a standby state. In a standby state, the cooking hob modes can be selected to heat a gas container.

Under the control of the hob is also the ability to change the power level of a, in particular individual, heater of the hob. It is thus possible, for example, that depending on the positioning of the cover on the installation surface, only the at least one heating element arranged closest to the recess is activated or deactivated.

With regard to a heating device designed as a gas burner, switching on and off means opening or closing a valve, in particular a safety valve, in the gas supply line. As a result, a particularly safe operation is achieved because a use of a tray ventilator is possible only when properly positioned lid.

In addition, it is possible with the installation of the cover to turn on the fan of the extractor device or to operate this in a predetermined power level.

A detection device for detecting at least one touch of a part of the arrangement by a user is for example designed, arranged and aligned such that a touch or touch gesture with a body part is detected. Depending on the embodiment, the detection device detects a locally limited contact on at least one touch point or a touch gesture. A touch gesture can be one-dimensional or two-dimensional. A touch gesture may also be a pattern or sequence of multiple touches in temporal and / or spatial sequence. It is also possible that several detection points are made available with the detection device.

The control device can be designed to activate the hob and / or the extractor device when a first contact of the user has been detected on a part of the arrangement, in particular on the decorative plate and / or panel. For example, the lifting device can be triggered by a touch.

The control device can also be designed to deactivate the hob and / or the extractor device, if a second touch of the user a part of the arrangement, in particular on the decorative plate and / or aperture has been detected. In this case, the first touch and the second touch may differ in the touch gesture and / or the contact point.

According to one embodiment, the household appliance may have a lifting device for lifting the lid out of the recess. The control device may be designed to control the lifting device in dependence on the position of the lid. For example, in the case of a lid placed on the footprint, the control of the lifting device is suppressed. The control device may be designed to control the lifting device in response to the user touching the cover or the cover. For example, it is possible to trigger the lifting device when the user touches the lid. In this case, it has proved to be advantageous for the triggering contact to require a predetermined contact gesture or a predetermined contact area or a predetermined contact sequence. The control device can be designed to control the lifting device in dependence on an operating state of the extractor device or of the hob. As a result, the lid can be raised automatically, for example, when the hob or the extractor device is turned on. In particular, with the switching on of the hob so the user is reminded to remove the lid from the recess and set up on the footprint.

In addition, the detection device can be integrated in the panel or the decorative panel and / or the lid. As a result, the position of the lid can be reliably detected.

A detection device for detecting at least one operating state of the extractor device, for example, is designed, arranged and aligned that state values are queried by a central electronics of the arrangement or the control of the hob in the control of the extractor device and / or by the control of the extractor device state values the central electronics of the arrangement and / or delivered to the control of the hob.

Another possibility detection device for detecting at least one operating state of the extractor device is that with a sensor, the speed of the fan or the flow velocity of Wrasens or an electric current of the extractor device is detected.

The controller may be configured to deactivate or limit the cooktop to a low power level when the extractor is operated at a high power level and / or to activate the cooktop or at a high power level Operate power level when the extractor device is operated at a low power level or is switched off.

A detection device for detecting at least one operating state of the at least one cooktop, for example, is designed, arranged and aligned so that state values are queried from a central electronics of the arrangement or by the control of the extractor device in the control of the cooktop and / or by the control of the cooktop Condition values are delivered to the central electronics of the arrangement and / or to the control of the extractor device.

Another possibility detection device for detecting at least one operating state of the hob is that with a sensor, the temperature or flame size at a heating element or the position of a cooking vessel or an electrical or electromagnetic size of a heating element, in particular an induction coil is detected.

The control device can be designed, for example, to deactivate the extractor device or to activate the operation of the extractor device with a low power level or to continue the operation of the extractor device with a low power level if the hob, in particular a heating element adjacent to the recess, is activated.

Furthermore, it is possible to activate the extractor device, in particular to activate the operation of the extractor device with a high power level, or to continue the operation of the extractor device with a high power level when the hob, in particular a directly adjacent to the recess heating element is disabled.

These two aspects are particularly interesting in combination with the detection of the position of the lid. So overall, the security level can be increased. This is ideally supplemented by a detection device for detecting at least one contamination value of the grease filter.

The soiling value represents the real or assumed amount of oil and fat in the grease filter. The contamination value is thus the degree of soiling of the grease filter and / or the duration of use of the grease filter since its last cleaning.

A detection device for detecting at least one contamination value of the grease filter is designed, arranged and aligned, for example, such that a counter of the extractor device counts the operating hours of the extractor device, in particular of the fan, and derives therefrom the contamination value. A further education of Detecting means for detecting at least one fouling value of the grease filter provides that the power level is taken into account in the form of a weighting.

The soiling value is reset when the grease filter is removed from the filter shaft for cleaning. For this purpose, the detection of the position detection of the grease filter in the filter shaft with an operator input, such as a touch detection can be combined.

The control device can be configured to deactivate the hob and / or the extractor device if the grease filter has a contamination value which is greater than a predetermined switch-off value. This improves the safety and performance of the assembly by preventing excessive saturation of the grease filter with fats and oils and making it easier to clean. It is also possible to design the controller in such a way that the hob and / or the extractor device to activate, in particular only to activate when the grease filter has a pollution value which is smaller than a predetermined switch-on. In this case, switch-off value and switch-on value of the contamination value are preferably identical. However, it is equally possible that the cut-off value and the switch-on value differ, with the cut-off value being greater than the switch-on value. The shutdown value thus represents a stronger contamination than the switch-on value. The monitoring of the contamination value can be carried out continuously, so that when the cut-off value is exceeded, the extractor device, at least the fan, is immediately displaced into a lower power level or switched off.

In addition, the future development of the contamination value can be determined continuously and, depending on the approach to the shutdown value, the power of the extractor device, in particular of the fan, can be reduced.

Exceeding the cut-off value is possible, for example, if the control of the extractor device pollutes the contamination value only every time the hob and / or the extractor device is switched on. As a result, the user can continue to operate the extractor device in a tolerance range when exceeding the Abschaltwertes during a cooking process.

A detection device for detecting at least one position of the grease filter is for example designed, arranged and aligned in such a way that a grease filter arranged in the filter shaft is detected. Depending on the embodiment, the detection device can be realized as an optical, capacitive, inductive, piezoelectric or magnetic sensor. This allows precise detection of the position. Preferably, the detecting means is for detecting at least one position of the grease filter in the Filter shaft, in particular arranged in or at or behind a wall of the filter shaft.

The control device may be designed to deactivate the hob and / or the extractor device when the grease filter is not positioned in the filter shaft. This avoids oil and grease getting deeply into the extractor device, in particular into the fan.

With regard to a heating device designed as a gas burner, switching on and off means opening or closing a valve, in particular a safety valve, in the gas supply line. As a result, a particularly safe operation is achieved because a use of a tray ventilator is possible only when properly positioned lid.

According to one embodiment, the control device of the arrangement and a control device of the extractor device and / or a control device of the hob are designed as one unit. Unit means in this context functional unit and / or unit and / or electronic unit.

The arrangement described above can be realized according to one embodiment as a single household appliance or as a combination of several household appliances.

Depending on the embodiment, the detection device can be realized as an optical, capacitive, inductive, piezoelectric or magnetic sensor. This allows precise detection of the position.

a flowchart of a method according to embodiment.

FIG. 1 shows a schematic representation of an embodiment of an arrangement 100 consisting of a fume extractor 200 and a hob 300. The hob 300 has a decorative plate 310 and at least one indicated by a dashed line heating element 320. With the heating element 320, a cooking container mounted on the hob 300 and not shown here can be heated. The heating element 320 is disposed below the decorative plate 310 in this exemplary embodiment.

According to the invention, other embodiments are possible in which the heating element 320 is arranged above the decorative plate 310, for example a heating element 320 designed as a gas burner.

The extractor device 200 has a diaphragm 210 with at least one recess 220 for removing vapors to below the plane of the decorative plate 310 and / or below the plane of the diaphragm 210. In the example shown, the panel 210 and the decorative panel 310 are made in one piece. The extractor device 200 further comprises a grease filter 230 for separating out grease and oil from the vapor, a filter shaft 240 for receiving the grease filter 230 and at least one cover 250 for covering the recess 220. In order to generate an air movement carrying the vapor, the extractor device 200 has a fan 270.

The arrangement 100 has a detection device 110 for detecting a contact of a part of the arrangement 100 by a user, a detection device 130 for detecting a position of the grease filter 230, and a detection device 140 for detecting the soiling value of the grease filter 230.

Furthermore, the arrangement 100 has a detection device 120 for detecting at least one operating state of the hob 300, in particular a heating element 320 and a detection device 160 for detecting at least one operating state of the extractor device 200.

The detection device 130 for detecting a position of the grease filter 230 is, for example, a mechanical or electrical contact switch and disposed in the filter well 240. It is also possible that the filter element 232 with the grease filter 230 has a permanent magnet 233 and the detection device 130 is, for example, a Hall sensor or a reed sensor. In these examples, the detection device 130 outputs a signal when the filter element 232 with the grease filter 230, that is, the grease filter 230 is inserted into the filter shaft 240 or is.

The detection means 140 for detecting the soiling value of the grease filter 230 consists of a data memory and a processing electronics, which counts the duration of use of the grease filter 230 after cleaning the grease filter 230, optionally weighted depending on a mode of the extractor device 200, and Stored.

In particular for weighting the duration of use of the grease filter 230, the detection device 140 accesses the operating state of the extractor device 200 determined or provided by the detection device 160. It is also possible, the detection device 140 alternatively or additionally uses the operating state of the hob 300 determined or provided by the detection device 120 during the weighting.

FIG. 2 shows a schematic representation of an embodiment of a fume extractor 200 of an arrangement 100 consisting of a cooktop, not shown, and the extractor device 200. The extractor device 200 is adapted to be positioned next to a hob in a kitchen environment in a worktop and operated.

The extractor device 200 has a diaphragm 210 with at least one recess 220 for discharging vapor to below the plane of the diaphragm 210. Shown is how a cover 250 for closing the recess 220 in the recess 220 is arranged.

Lid 250 includes a first lid magnet member 251, a second lid magnet member 252, a third lid magnet member 253, and a fourth lid magnet member 254. The four lid magnet elements are arranged in pairs opposite one another on the two side walls 255 within the lid housing 256. Similarly, a first aperture magnet element 211, a second aperture magnet element 212, a third aperture magnet element 213 and a fourth aperture magnet element 214 are integrated into the aperture 210, wherein the four aperture magnet elements are arranged adjacent to the recess 220. Here, the two diaphragm magnet elements 211, 212 adjacent to a first longitudinal side of the recess 220 and the two diaphragm magnet elements 213, 214 adjacent to a first longitudinal side opposite the second longitudinal side of the recess 220 are arranged.

In the covered state of the recess 220, the two lid magnet elements 251, 254 and the two diaphragm magnet elements 211, 214 are arranged substantially at the same height, which is indicated by a first dashed line 201. The remaining magnet elements 252, 253, 212, 213 are arranged in an analogous manner along a second dashed line 202.

Depending on whether the cover 250 is placed on a portion of the diaphragm 210 adjacent to the first longitudinal side of the recess 220 or a portion of the diaphragm 210 adjacent to the second longitudinal side of the recess 220, either the first lid magnet element is in the raised state of the lid 250 251 and the first aperture magnet element 211 and the second lid magnet element 252 and the second diaphragm magnet elements 212 or the third lid magnet element 253 and the third Shutter magnet element 213 and the fourth lid magnet element 254 and the fourth diaphragm magnet elements 214 opposite. In this case, the lid 250 is magnetically held by the mutual attraction between the respective opposing magnetic elements on the diaphragm 220.

Alternatively, the lid housing 256 may be made of a magnetically conductive material, so that the lid housing 256 is held in the erected state by the magnetic force of the diaphragm magnet elements. Here, the cover magnet elements can be omitted. Conversely, the aperture 210 may be realized at least in the area of a footprint for setting up the lid 250 of a magnetically conductive material, wherein the lid 250 is held in the erected state by the magnetic force of the lid magnet elements. In this case, the diaphragm magnet elements can be omitted.

The cover and diaphragm magnet elements described above are, for example, permanent magnets. The lid 250 is placed adjacent to the recess 220 on its longitudinal side. In this case, the cover 250 extends at least over an entire length of the recess 220. The cover 250 thus acts as a kind of partition between the recess 220 and a adjacent to the recess 220 can be arranged or arranged cooktop, such as a gas hob or grill. By means of the cover 250 set up in this way, the recess 220, for example of gas or flames emanating from the cooktop, can be shielded in the region of the cooktop. The hob can, as in FIG. 1 shown to be integrated in the aperture 210.

FIG. 3 shows a schematic representation of an embodiment of a fume extractor 200 with the lid 250 set up.
