Description

The invention relates to extractor hoods, in particular extractor hoods for extracting cooking vapors by means of an air flow, with a housing which has at least one air intake opening and at least one air outlet for the air flow, at least one fan arranged in the housing for generating the air flow, and at least one fan in the housing separating element arranged in the air flow between the air intake opening and the fan for separating one or more components of the cooking vapors, in particular fat and/or oil, in the air flow, the air flow in the housing being guided from the air intake opening via the separating element to the fan and from the fan is blown out of the housing via the air outlet.

Such extractor hoods or such extractor hoods can be found in every well-equipped kitchen today. The main disadvantages of the previously known solutions are the sometimes complicated operation and poor visibility of operating parameters, as well as poor room illumination due to integrated lighting units.

It is therefore the object of the invention to specify an improved fume hood or an improved fume hood that enables simple, intuitive and safe operation, offers good visibility of operating parameters and allows good and individually configurable room illumination.

This object is achieved by an extractor hood with the features of claim 1 and by an extractor with the features of claim 5 or with the features of claim 10.

According to the invention, the extractor hood has at least one motorized height adjustment device for changing the vertical distance of the extractor hood from the hob. Because a first gesture detection device is set up to detect gestures of an operator of the extractor hood and convert them into control signals for controlling the height adjustment device, the extractor hood can be operated easily, intuitively and safely. The vertical distance between the extractor hood and the hob underneath can be changed simply by gestures of an operator. This means that the extractor hood can be brought to the optimum height for cooking using the motorized height adjustment device without having to touch the extractor hood or use a remote control. This makes it possible to change the height, even if you have ingredients or leftover ingredients for the dish to be cooked on your fingers or are holding them in your hands, without the extractor hood or the remote control being soiled by your hands. For example, a gesture by the operator, in which the operator's hand is moved from bottom to top, can trigger activation of the height adjustment device, which results in an increase in the vertical distance between the extractor hood and the hob. On the other hand, a gesture by the operator in which the operator's hand is guided from top to bottom can trigger activation of the height adjustment device, which results in a reduction in the vertical distance between the extractor hood and the hob. Furthermore, for example, a gesture by the operator in which the operator's hand is guided from left to right can cause an increase in the power of the fan. While, for example, a gesture by the operator, in which the operator's hand is moved from right to left, can result in a reduction in the performance of the fan. Furthermore, for example, a gesture by the operator, in which the operator's hand is moved from front to back, can cause lighting to be switched on. For example, while a gesture by the operator at which the operator's hand is moved from the back to the front, can result in the lighting of the extractor hood being switched off. In addition to controlling the height adjustment device, other settings can also be made on the extractor hood via the gesture detection unit according to the invention. This enables easy, intuitive and safe operation of the extractor hood.

Advantageous refinements and developments of the invention result from the dependent claims. It should be pointed out that the features listed individually in the claims can also be combined with one another in any technologically meaningful manner and thus show further refinements of the invention.

According to an advantageous embodiment of the invention, it is provided that the gesture detection device comprises an optical ToF sensor which is designed to detect the distance between the extractor hood and the hob and which is also designed to detect the change in the distance between the extractor hood and the hob over time To capture the operator's hand when performing a gesture. By measuring the distance between the extractor hood and the hob, the current position for the extractor hood and the optimal position to be reached for cooking can easily be determined using the optical ToF sensor. As a result, the height adjustment device can also be controlled via the temporal change in the distance between the extractor hood and the operator's hand when performing a hand gesture, which results in optimal positioning of the extractor hood with regard to the vertical distance to the hob. Since the ToF sensor can be used both to record gestures from an operator and at the same time to record the vertical distance of the extractor hood to the hob, multiple sensors are not required to determine this information.

An embodiment that provides that the gesture detection device is set up to respond only to gestures that are performed in an area below the extractor hood and above a minimum distance from the hob surface is particularly preferred. With the minimum distance from the hob surface, operating errors via the gesture detection device can be prevented very easily, since this distance from the hob surface prevents the gesture detection device from responding to movements by the operator when cooking on the hob. For example, ingredients of the dishes can be easily added to the cookware provided by hand on the cooktop, or the contents of the cookware can simply be turned or stirred without the gesture detection device responding to these movements of the operator when cooking on the cooktop. To operate the hood, the operator must perform a hand gesture in an area below the hood and above the minimum distance from the hob surface. All you have to do is lift your hand into the detection area above the minimum distance from the cooktop surface.

A particularly advantageous embodiment of the invention relates to the fact that the minimum distance is 10 cm to 60 cm, preferably 20 cm to 40 cm. With such a minimum distance, cookware and ingredients can be easily manipulated on the cooktop during cooking without the gesture detection device responding to these hand movements. This ensures simple, intuitive and safe operation of the extractor hood.

Furthermore, the subject matter of the invention is an extractor hood, in particular an extractor hood as described above and in more detail below, for extracting cooking vapors by means of an air flow, with a housing that has at least one air intake opening and at least one air outlet for the air flow, at least one in the housing arranged fans for generating the air flow, a fan controller for controlling the fan, in particular for activating different fan levels, and at least one separating element arranged in the housing in the air flow between the air intake opening and the fan for separating one or more components of the cooking vapors, in particular fat and/or oil , in the airflow, wherein the airflow in the housing is guided from the air intake opening via the at least one separating element to the fan and from the fan is blown out of the housing via the air outlet, and a capacitive sensor field of a, in particular second, gesture detection device, which is designed to detect gestures performed in front of the sensor field by an operator of the extractor and to convert them into control signals for controlling the fan control. In addition to extractor hoods, this solution is also suitable for other extractors, such as down-draft systems, which consist of a hob and a corresponding extractor arranged underneath. In the case of the extractor hood as described above and in more detail below, the capacitive sensor field can also be part of a second gesture detection device, but can also be part of the gesture detection device that is set up to detect gestures by an operator of the extractor hood and convert them into control signals for controlling the height adjustment device implement. In the latter case, the common gesture detection device would therefore be set up to detect gestures of an operator of the extractor hood and convert them into control signals for controlling the height adjustment device, i.e. also to detect gestures performed by an operator in front of the sensor field and convert them into control signals for controlling the fan and /or implement light control. The gestures of an operator can be easily and safely recorded via the sensor field and converted into control signals for controlling the fan and/or light control, i.e. in particular for setting specific fans and/or light levels, without touching the extractor hood or one of the components of the extractor is necessary. For this purpose, the sensor field generates an electromagnetic field, which is already changed by the operator's approach with a hand or a finger. The change in the electromagnetic field caused by the gestures performed by an operator in front of the sensor field is detected via the sensor field and simply converted into control signals for controlling the fan and/or light control.

A particularly advantageous embodiment of the fume hood, in particular the fume hood described in more detail above and below, provides that the capacitive sensor field is designed as a film and is arranged on a glass pane, preferably on a housing front. The sensor field can be easily attached as a foil to the surfaces of the extractor hood or arrange one of its components. The sensor field can thus also be easily arranged on a pane of glass, so that gestures performed by an operator in front of the pane of glass can be detected via the sensor field located behind it. The sensor field is thus protected from damage by the glass pane, and on the other hand the glass pane does not have to be touched directly to activate the fan control.

An advantageous embodiment of the extractor, in particular the extractor hood as described above and in more detail below, provides that the first and/or the second gesture detection device are also set up to convert the detected gestures of the operator into control signals for controlling an integrated hob lighting and/or a implement integrated ambient lighting. In addition to the fan control, other extractor functions can also be set, for example via the capacitive sensor field, so the integrated hob lighting and/or an integrated ambient lighting can also be switched on or off. In addition to controlling the height adjustment device, gestures of an operator detected via the ToF sensor, for example, can also be converted into control signals for controlling integrated hob lighting and/or integrated ambient lighting and/or fan control. In the case of the extractor hood as described above and in more detail below, the capacitive sensor field can also be part of a second gesture detection device, but can also be part of the gesture detection device that is set up to detect gestures by an operator of the extractor hood and convert them into control signals for controlling the height adjustment device implement. In the latter case, the common gesture detection device would therefore be set up in an extractor hood both to detect gestures by an operator of the extractor hood and to convert them into control signals for controlling the height adjustment device, i.e. for example also to detect gestures performed by an operator in front of the sensor field and convert them into control signals for controlling the fan control or to implement control signals for controlling an integrated hob lighting and/or an integrated ambient lighting.

An embodiment of the fume hood, in particular the fume hood described in more detail above and below, is particularly advantageous, which provides that several individually controllable LED lights are set up to be individually controlled to display operating parameters of the fume hood. The individually controllable LED lights can be used to display current operating parameters of the extractor hood, such as the power of the fan, i.e. the selected fan level, or the remaining service life of a filter until it is changed or regenerated. The expiry of cleaning intervals of the separating element can also be displayed.

According to a preferred embodiment of the fume hood, in particular the fume hood described in more detail above and below, it is provided that the individual LED lights are arranged next to one another and thus form at least one LED module. For example, the selected fan level or the remaining service life of a filter until it is replaced or regenerated can be displayed via the LED module. Furthermore, the expiration of cleaning intervals of the separating element can also be displayed. For this purpose, the individual LED lights arranged next to each other are controlled independently of one another in the LED module in order to display the operating parameters of the extractor hood, for example via the number of LED lights lit next to each other. For this purpose, the LED lights can be controlled independently of one another by means of a controller, which enables the reproduction of a wide variety of lighting effects for the various operating states of the extractor hood. If desired, the user can customize these lighting effects and program them using a smart device.

Furthermore, the subject matter of the invention is a fume hood, in particular a fume hood as described above and in more detail below, in particular a fume hood as described above and in more detail below, for extracting cooking vapors by means of an air flow, with a housing that has at least one air intake opening and at least has an air outlet for the air flow, at least one fan arranged in the housing for generating the air flow, at least one in the housing in the airflow between the air intake opening and the fan for separating one or more components of the cooking vapors, in particular fat and/or oil, in the airflow, the airflow being guided in the housing from the air intake opening via the separating element to the fan and from the Fan is blown out of the housing via the air outlet, with an integrated ambient lighting of the extractor hood consisting of several individually controllable LED lights arranged next to each other, which are designed to be individually controlled to display operating parameters of the extractor hood. The operating parameters of the extractor hood can be displayed in a particularly easy-to-understand and clearly visible manner using the LED lights arranged side by side thanks to the integrated ambient lighting of the extractor hood. The LED lights arranged next to each other can be easily controlled individually, so that the operating parameters can be displayed by the LED lights arranged next to each other in the integrated ambient lighting of the extractor by means of a defined activation of the individual LED lights. In addition to creating mood lighting, the lighting provided for this purpose on the extractor can also be used to display the operating parameters of the extractor. This means that the operating parameters can be seen very easily by activating the ambient lighting, even from a greater distance, for example in open living areas.

According to a preferred embodiment of the extractor, in particular the extractor hood as described above and in more detail below, it is provided that an air quality sensor is arranged in the extractor, the air quality sensor being set up to measure the air quality of the air flow, the integrated ambient lighting being set up for this purpose , depending on the measurement data of the air quality sensor, to display the air quality of the air flow as an operating parameter. The quality of the air in the air flow can be easily recorded using the measurement data from the air quality sensor. Thanks to the activation of the LED lights of the ambient lighting, which is dependent on the measurement data, the measured air quality can be visualized so that the user receives immediate visual feedback when the fan control based on the readings of the air quality sensor, increases or decreases the power of the fan in order to achieve a satisfactory separation of one or more components of the cooking fumes.

An advantageous embodiment of the fume hood, in particular the fume hood described in more detail above and below, provides that the integrated ambient lighting is set up to display a selected fan speed of the fan as an operating parameter. The ambient lighting can also be easily controlled in order to clearly display the fan level of the fan control manually selected by the user. In this way, the selected fan level can also be recognized from a greater distance, for example in open living areas.

An embodiment of the extractor hood, in particular the extractor hood described in more detail above and below, is particularly advantageous, which provides that the integrated ambient lighting is set up to display the remaining service life of a filter until the filter is changed and/or regenerated as an operating parameter. The ambient lighting can therefore be easily controlled in order to clearly show the remaining service life of a filter until the filter is changed and/or regenerated. As a result, the remaining service life of a filter until the filter is changed and/or regenerated can also be clearly identified from a greater distance, for example in open living areas.

According to a preferred embodiment of the extractor, in particular the extractor hood as described above and in more detail below, it is provided that the integrated ambient lighting is set up to display the remaining time until the end of a maintenance interval of the separating element as an operating parameter. The ambient lighting can thus be easily controlled in order to clearly show the remaining time until the end of a maintenance interval for the separating element. So the remaining time until the end of a Maintenance interval of the separating element can be easily recognized from a greater distance, for example in open living areas.

An advantageous embodiment of the extractor, in particular the extractor hood as described above and in more detail below, provides that a data interface for receiving external data is provided on the extractor, with the integrated ambient lighting being set up to display the operating parameters based on the external data. External data can also be used via the data interface to control the LED lights of the integrated ambient lighting. For example, external data from a smartphone can be used directly via a wireless data interface to control the LED lights of the integrated ambient lighting and to display this data as operating parameters. However, external data from an Internet server can also be used, for example via a wired data interface, to control the LED lights of the integrated ambient lighting and to display this data as operating parameters. In this way, lighting scenarios desired by the user for controlling the LED lights of the integrated ambient lighting can be transmitted to the extractor hood very easily using the external data via the data interface. For example, the display of operating parameters can be easily adapted to the wishes of the user and the living situation or the rest of the facility.

According to a preferred embodiment of the extractor, in particular the extractor hood as described above and in more detail below, it is provided that the integrated ambient lighting is set up to display the remaining time until the end of an adjustable timer period as an operating parameter. Similar to a classic egg timer, the remaining time until the end of an adjustable timer can be displayed via the integrated ambient lighting. As a result, the remaining time until the end of an adjustable timer period can be clearly seen even from a greater distance, for example in open living areas.

An advantageous embodiment of the fume hood, in particular the fume hood described in more detail above and below, provides that the individual LED lights are set up to be controlled individually with regard to the generation of a light color and/or light intensity. With the control of the individual LED lights with regard to the generation of a light color and/or light intensity, there are countless possibilities for displaying the operating parameters, which provide simple and understandable information about the extractor hood.

An embodiment of the extractor hood, in particular the extractor hood described in more detail above and below, is particularly advantageous, which provides that the individual LED lights are arranged next to one another and thus form at least one LED module that generates at least one continuous light band. The continuous light band makes it particularly easy to generate bar displays to show the operating parameters. To do this, the individual LED lights of the LED module arranged next to each other are simply controlled in order to display the bar displays for the operating parameters.

According to a preferred embodiment of the extractor hood, in particular the extractor hood as described above and in more detail below, it is provided that the extractor hood is designed as an extractor hood for extracting cooking vapors over a hob by means of an air flow, with at least one motorized height adjustment device for changing the vertical distance of the Extractor hood from the hob, wherein the height adjustment device comprises a ceiling suspension with which the extractor hood can be attached to a ceiling in a height-adjustable manner, the integrated ambient lighting being arranged on an upper side of the preferably cuboid housing and the LED lights of the ambient lighting being set up to emit a light in to emit in the direction of the ceiling suspension. The arrangement of the integrated ambient lighting on a top side of the housing offers an excellent opportunity to improve the room illumination with lighting integrated into the extractor hood. In addition, the operating parameters of the extractor hood can also be made visually appealing in this way being represented. With the emission of the light in the direction of the ceiling suspension, an indirect lighting of the living room can be realized. For this purpose, the ceiling suspension can have a surface suitable for reflecting and/or scattering the light. Operating parameters can also be displayed with the indirect lighting, for example by changing the light color and/or light intensity.

An advantageous embodiment of the extractor hood, in particular the extractor hood described in more detail above and below, provides that the integrated ambient lighting has individual LED lights arranged next to one another, which form at least one LED module, which forms a continuous light band on at least one side surface, in particular a housing front of the preferably cuboid housing forms. The particularly easy bar displays for displaying the operating parameters can be generated via the continuous light band on a side surface of the housing. With the arrangement on the side surface of the housing, bar displays for the operating parameters can be displayed in a clearly visible manner by activating the individual LED lights of the LED module arranged next to one another. In addition to the housing front of the preferably cuboid housing, the light strip can also extend continuously over other side surfaces, such as the side parts or the rear of the housing. As a result, the operating parameters can be clearly seen from all sides of the extractor hood, even from a greater distance, for example in open living areas.

In the figure 1 denoted by the reference numeral 1 is an extractor hood according to the invention. The extractor hood 1 is used to extract cooking vapors from a hob 2 ( 2 ) by means of an air flow 3 ( 4 ).

In the exemplary embodiment, the extractor hood 1 has a height-adjustable housing 4, which has an air intake opening 5 and an air outlet 6 ( 3 ) for airflow 3 ( 4 ) having. In the housing 4 is at least one (not shown) fan for generating the air flow 3 ( 4 ) arranged. In addition, at least one separating element (not shown) is arranged in the housing 4 and is used to separate one or more components of the cooking vapors, in particular fat and/or oil, from the air flow 3 ( 4 ), serves. This separating element is in the housing 4 between the air intake opening 5 and the fan in the air flow 3 ( 4 ) arranged. The air flow 3 ( 4 ) is guided in the housing 4 from the air intake opening 5 via the separating element to the fan. From the fan, the air flow 3 ( 4 ) then via the air outlet 6 ( 3 ) blown out of the housing 3. The extractor hood 1 also has a motor-driven height adjustment device 7 ( 3 and 4 ) to change the vertical distance 8 ( 2 and 4 ) of the extractor hood 1 from the hob 2. In the exemplary embodiment, the height adjustment device 7 ( 3 and 4 ) designed as a cable suspension, via which the housing 4 of the extractor hood 1 is connected to a ceiling suspension 21. By winding and unwinding the suspension cable via a motor of the height adjustment device 7 ( 3 and 4 ) the vertical distance 8 ( 2 and 4 ) the extractor hood 1 from the hob 2 ( 2 ) can be changed by the housing 4 being roped down from the ceiling suspension 21 or via the height adjustment device 7 ( 3 and 4 ) is pulled up again. A gesture detection device 9 is provided on the extractor hood, which is set up to detect gestures of an operator of the extractor hood 1 and convert them into control signals for controlling the height adjustment device 7 . In this way, simple, intuitive and safe operation of the extractor hood 1 can be implemented, because the vertical distance 8 ( 2 ) of the extractor hood 1 to the hob 2 underneath ( 2 ) can easily be changed. This means that the extractor hood 1 can be brought to the optimum height for cooking via the motor-driven height adjustment device 7 without having to touch the extractor hood 1 by hand or using a remote control, as shown in FIG figure 4 you can see.

In figure 2 it can be seen that the housing 3 of the extractor hood 1 rests directly on the ceiling mount 21, so that the distance 8 to the hob 2 underneath is at a maximum. However, this distance 8 is unsuitable for cooking, since the cooking vapors are not reliably sucked up by an air flow here, so that components of the cooking vapors, in particular fat and/or oil, cannot be effectively separated via the separating element. The height adjustment device 7 ( 3 ) advantageously via the gesture detection device 9 ( 1 ) are operated, the gestures of an operator of the extractor hood 1 are recorded and converted into control signals for controlling the height adjustment device 7 ( 4 ) implemented. The gesture detector 9 ( 1 ) advantageously comprises an optical ToF sensor 10 ( 1 ), which is designed to record the vertical distance 8 between the extractor hood 1 and the hob 2. Furthermore, the ToF sensor 10 ( 1 ) designed to detect the temporal change in the distance 11 between the extractor hood 1 and the operator's hand 12 when performing a gesture. In this way, both the gesture detection and the distance measurement to the hob 2 can be performed via a sensor. The distance measurement is particularly useful when the gesture detection device 9 ( 1 ) is also set up to respond only to gestures that are performed in a defined area below the extractor hood 1 and above a minimum distance from the hob surface 13. As a result, erroneous operations via the gesture detection device 9 ( 1 ) can be prevented because the minimum distance to the cooktop surface 13 means that the gesture detection device 9 ( 1 ) on movements of the operator when cooking on the hob 2 can be prevented. The minimum distance from the hob surface 13 should preferably be between 10 cm and 60 cm, preferably 20 cm to 40 cm. In the figure 2 a capacitive sensor field 15 can also be seen. Gestures performed by an operator of the fume hood 1 in front of this sensor field 15 are detected by the sensor field 15 and converted into control signals for controlling a fan controller, which is designed to control the fan, in particular to activate different fan speeds. The capacitive sensor field 15 can be part of a second gesture detection device 16, but can also be part of the gesture detector 9 ( 1 ), which is set up to detect gestures by an operator of the extractor hood 1 and to convert them into control signals for controlling the height adjustment device 7 ( 3 ) to implement. In the latter case, the common gesture detection device 9, 16 would therefore be set up to detect both gestures of an operator of the extractor hood 1 in an extractor hood 1 and to convert them into control signals for controlling the height adjustment device 7 ( 4 ) ie also to detect gestures performed by an operator in front of the sensor field 15 and to convert them into control signals for controlling the fan control. The sensor field 15 generates an electromagnetic field, which is already generated by the operator's approach with the hand 12 ( 2 ) or a finger is changed. In this way, the gestures of an operator can be easily and reliably detected and converted into control signals for controlling the fan control without having to touch the extractor hood 1 or one of the components of the extractor hood 1, for example a remote control. The capacitive sensor field 15 is preferably in the form of a film which is arranged on a glass pane, preferably on a housing front 14 . In this way, the sensor field 15 can be arranged very easily on surfaces of the extractor hood 1 or one of its components. The gesture detection device can detect gestures performed by an operator in front of the glass pane via the sensor field 15 located behind it. This protects the sensor field 15 from being damaged by the glass pane, but on the other hand the glass pane does not have to be touched directly to activate the fan control.

Provision is also made for the first and/or the second or a common gesture detection device 9, 16 to convert the detected gestures of the operator into control signals for controlling an integrated hob lighting 17 ( 1 ) and/or an integrated ambient lighting 18 to implement. The integrated hob lighting 17 for illuminating the hob 2 can thus be switched on or off again via the operator's gestures. In addition, the operator's gestures can also be used to control ambient lighting 18 integrated into the extractor hood 1 in order to adapt the appearance of the extractor hood 1 and the room lighting to the mood of the operator or the time of day.

In figure 3 it can be seen that the distance between the housing 4 and the ceiling suspension 21 was increased by unwinding the suspension cable over the motor of the height adjustment device 7 in order to increase the vertical distance 8 between the extractor hood 1 and the hob 2 ( 4 ) to shrink as it is in figure 4 opposite to figure 2 you can see. The air outlet 6 ( 3 ) freely so that the airflow 3 ( 4 ) can leave the housing 4 unhindered.

the figure 4 shows the extractor hood 1 according to figures 1 and 2 , wherein the housing 4 via the height adjustment device 7, as already in figure 3 shown roped from the ceiling suspension 21 is shown. As a result, the vertical distance 8 of the extractor hood 1 from the hob 2 is increased via the height adjustment device 7 compared to the situation in figure 2 scaled down. In the position shown here of the housing 4 of the extractor hood 1 relative to the hob 2, the vertical distance 8 is optimal, so that the cooking vapors from the cookware 22 placed on the hob 2 can be drawn off via the air flow 3 at the air intake opening 5 ( 1 ) to be sucked in. Subsequently, individual components of the cooking vapors, in particular fat and/or oil, are separated via the separating element and the air flow 3 can enter the housing 4 via the air outlet 6 ( 3 ) left again. In addition, several individually controllable LED lights 19 are provided to display the operating parameters of the extractor hood 1 . In this way, current operating parameters of the extractor hood 1, such as the power of the fan, ie the selected fan level, or the remaining service life of a filter until it is changed or regenerated can be displayed very easily. The expiration of cleaning intervals of the separating element can also be displayed in this way. For this purpose, individual LED lights 19 are advantageously arranged next to one another and thus form an LED module 20. The individual LED lights 19 arranged next to one another in the LED module 20 can then be controlled in such a way that the operating parameters of the extractor hood 1, for example, via the number of adjacently lit LED lights 19 are shown. The individually controllable LED lights 19 can be part of an integrated ambient lighting 18 of the extractor hood 1, the LED lights 19 being set up to to be controlled individually for displaying operating parameters of the extractor hood 1 . The ambient lighting 18 can be used to display various operating parameters, such as the air quality of the air flow 3, the fan level selected manually by the user, the remaining service life of a filter until it is replaced and/or regenerated, the time remaining until the end of a maintenance interval for the Separation element, the remaining time until the end of an adjustable timer period or external data received via a data interface are displayed. The operating parameters of the extractor hood 1 can be displayed in a particularly easy-to-understand and clearly visible manner by the integrated ambient lighting 18 of the extractor hood 1 . For this purpose, the LED lights 19 arranged next to one another can be easily controlled individually, so that the operating parameters can be displayed by the LED lights 19 arranged next to one another of the integrated ambient lighting 18 of the extractor hood 1 via a defined activation of the individual LED lights 19 . Thus, the ambient lighting 18 can also be used to display operating parameters of the extractor hood 1 in addition to producing mood lighting. As a result, the operating parameters can be seen very easily via the activation of the ambient lighting 18 even from a greater distance, for example in open living areas. Arranged next to one another, the individual LED lights 19 preferably form an LED module 20 that produces a continuous band of light. The light strip makes it particularly easy to generate bar displays to show the operating parameters. To do this, the individual LED lights 19 of the LED module 20 arranged next to each other are simply controlled in order to display the bar displays for the operating parameters, as shown in figure 4 you can see.

the figure 5 shows an inventive extractor hood 1 with appropriate ambient lighting 18. The individual LED lights 19 ( 2 ) here arranged next to each other also form an LED module 20, which generates a continuous band of light. The individual LED lights 19 ( 4 ) can be controlled individually with regard to the generation of a light color and/or light intensity. The LED lights 19 ( 2 ) of the LED module 20 ( figure 3 ) are here behind one Arranged diffuser disc, so that by appropriate control with regard to the light color and the light intensity of the individually controlled LED lights 19 ( 2 ) of the LED module 20 ( 3 ) soft transitions are created and the individual LED lights 19 ( 4 ) do not dazzle the user or are not recognizable as individual LED light points. In this embodiment, the integrated ambient lighting 18 has numerous individual LED lights 19 ( 4 ), which the LED module 20 ( 3 ) form that forms a continuous band of light on all side surfaces 24 of the cuboid housing 4 . As a result, operating parameters can be displayed both on the housing front 14 and on the side parts 25, as well as on the back of the extractor hood 1. The operating parameters shown are thus clearly visible from all sides 14, 25 of the extractor hood 1. Color gradients along the continuous light band can also be used to display the operating parameters, so that the colors also migrate or change along the light band. In figure 5 Among other things, the basic colors blue 26, red 27 and yellow 28 with gradients 40 can be seen.

the figure 6 shows another view of the extractor hood 1 according to FIG figure 5 . In this representation, the positions of the primary colors red 27 and yellow 28 have moved and the primary color blue 26 ( figure 5 ) has disappeared from the field of vision, while the basic color green 29 is generated in the field of vision on the front of the housing 14. This simple change in the colors and intensities of the light of the individually controlled LED lights 19 ( 4 ) of the ambient lighting 18 enable numerous options for visualizing the operating parameters of the extractor hood 1 and for creating a mood light. In the execution according to figures 5 and 6 the housing 4 of the extractor hood 1 is provided with frosted glass panes 16 so that the LED lights 19 ( 2 ) of the ambient lighting 18 in addition to the light band generated by the LED module 20 also allow backlighting 30 of the frosted glass pane 16 . As a result, the operating parameters shown can also be seen on the frosted glass panes 16 .

In contrast, in figure 7 another extractor hood 1 according to the invention is shown, in which case the cladding of the housing 4 is black and opaque. The ambient lighting 18 is also provided here by several individually controllable LED lights 19 ( 2 ) formed, which are set up to be controlled individually to display operating parameters of the extractor hood 1. The individual LED lights 19 ( 4 ) are controlled individually with regard to light color and/or light intensity. The continuous light band shows the LED lights (19 ( 4 ) is formed, in the representation shown here the basic colors blue 26, green 29, yellow 28 and red 27 with soft gradients 40. These gradients 40 are also generated here by a diffuser disk that is placed in front of the LED lights 19 ( 2 ) is arranged. In the embodiment shown here, it can also be seen that the integrated ambient lighting 18 also has a number of LED lights 19 on the upper side 23 of the preferably cuboid housing 4 . These LED lights 19 of the ambient lighting 18 are set up to emit light in the direction of the ceiling suspension 21 . The arrangement of the integrated ambient lighting 18 on an upper side 23 of the housing 4 offers the possibility of improving the room illumination. However, operating parameters of the extractor hood 1 can also be presented in a visually appealing manner. By radiating the light in the direction of the ceiling suspension 21, indirect lighting of the living space can be achieved. However, operating parameters can also be represented, for example, by changing the light color and/or light intensity. In the lighting situation shown here, the activation of the LED lights 19 of the ambient lighting 18 on the upper side 23 of the housing 4 is based on the activation of the LED lights 19 ( 4 ) of the ambient lighting 18 on the front of the housing 14. This means that the operating parameters shown can be seen particularly well, even from a distance. In addition, the coordinated display of the operating parameters creates a visually appealing overall picture of the extractor hood 1.

Such an overall picture can also be seen in the extractor hood 1 according to the invention, which figure 8 is pictured. In addition to the continuous light band through the LED module 20, this extractor hood 1 also has via ambient lighting 18 ( 7 ) at the top 23 ( 7 ) of the housing 4, which in accordance with the execution figure 8 is equivalent to. Here the entire light band of the LED module 20 is illuminated in blue color 26 with the same intensity, for example. Corresponding lighting can also be found on the ceiling suspension, which is controlled by the ambient lighting 18 ( 7 ) from the top 23 ( 7 ) of the suspended housing 4 is radiated.

the figure 9 however, shows the extractor hood 1 according to figure 8 , whereby here from the left edge of the light band of the LED module 20 instead of blue light 26 ( 8 ), a light with a slight purple hue 31 is produced. For this purpose, the individually controllable LED lights 19 ( 4 ) to be controlled individually. In this way, for example, bar charts for displaying operating parameters of the extractor hood 1 can be generated via the light band that is generated. Corresponding to the illustration of the light band, the ceiling suspension 21 in this exemplary embodiment is also covered by LED lights 19 ( 7 ) of the ambient lighting 18 ( 7 ) at the top 23 ( 7 ) of the suspended housing 4 of the extractor hood 1 illuminated with colored light.

the figure 10 shows the extractor hood 1 according to figures 8 and 9 in another way to control the LED lights 19 ( 4 ) of the ambient lighting 18. Here the light band is generated by the LED module 20 with a violet light 32 that the LED lights 19 ( 2 ) of the ambient lighting 18 is emitted. Also at the top 23 ( 7 ) corresponding violet light is emitted in the direction of the ceiling suspension 21. Color waves can also be displayed with the LED module 20 .

In the figure 11 is also the hood according to the Figures 8 to 10 shown. A smartphone 33 can also be seen here, via which the individually controllable LED lights 19 ( 2 ) of the ambient lighting 18 can be controlled. The user's color preferences, which they can select via an application 34 on the smartphone 33 , can be transmitted to the extractor hood 1 via a data interface for receiving external data at the extractor hood 1 . The integrated ambient lighting 18 is set up to display the operating parameters based on the transmitted external data according to customer requirements. The desired colors can also be selected by the user via the application 34 on the smartphone 33 for room lighting with the ambient lighting 18 . The ambient lighting 18 can thus be controlled very easily using external data which is transmitted via the data interface of the extractor hood 1 . As can be seen on the smartphone 33, the application 34 offers a choice of colors from a color gradient 35. The extractor hood 1 can thus be tailored particularly advantageously to the wishes of the user.

the figure 12 shows another view of the extractor hood 1 according to the Figures 8 to 11 , the ambient lighting 18 being set here in such a way that a punctiform sparkle 36 takes place in a desired color along the light band generated on the LED module 20 .

As in figure 13 can be seen, this twinkling 36 can also run in a kind of running light along the light band generated by the ambient lighting 18 on the LED module 20 . In this way, for example, the end of an adjustable timer period can be signaled, since this type of lighting is very conspicuous and can therefore also be seen well from a distance.

In the Figures 14 to 16 can also be seen that the extractor hood 1 according to Figures 8 to 13 can also represent the operating parameters by changing the light intensity of the ambient lighting 18 . here is in figure 14 the light band of the ambient lighting 18 with blue light 26 in a high intensity 37 is shown. In figure 15 on the other hand, the light intensity of the blue light 26 is weakened 38 at the edges, so that a remaining time can be displayed in a bar chart, for example. In figure 16 on the other hand, a bright point of light 39 is due to the increase in the light intensity of individual LED lights 19 ( 2 ) is shown, so that an operating parameter of the extractor hood 1 can be clearly displayed, for example, by moving this point of light along the light band generated by the LED module 20 .

With the ambient lighting 18, start sequences, light scenes, click acknowledgments, movement actions, music visualizations, an update loading bar, a pairing with the smartphone or an end sequence can be displayed on the extractor hood 1.
