Preferably the operation parameters of the extraction device and/or the cooking hob are selected from the group comprising the selection and/or change of the fan, regulation of the power level of the fan, the rotational speed of the fan, preferably the rotational speed of the fan wheel , the suction capacity of the fan, interval operations of the extraction device , the power level of the heating zones of the cooking hob, selection of a heating zone and/or changing of a heating zone of the cooking hob, heat output of the heating zones of the cooking hob, heat output density of the heating zones of the cooking hobs .
The interface unit is a communication device between the extraction control and hob control . The interface unit is particularly configured to communicate by means of a wireless and/or wiring connection with the extraction control and the hob control . This means that the interface unit is on the one hand connected with wire or wireless to the extraction control and on the other hand connected with wire or wireless to the hob control . The interface unit is preferably a data processing unit , wherein the data is processed and/or executed, operations are trans formed, transmitted and/or stored . In other words , the interface unit preferably receives , trans forms , stores , transmits and/or executes data . Furthermore , the interface unit is preferably integrated in and/or a part of the extraction control or in/of the hob control . This means that the interface unit is preferably arranged in the combination appliance . Alternatively, the interface unit may be arranged at an external device , for example an external server, preferably a part of a smart home system, such as Google Home®, Amazon Echo®, Apple Homepod® or the like , and/or a computer device and/or a mobile device , such as a tablet or mobile phone , detached from the combination appliance . In this case , the interface unit is configured to communicate by means of wireless connection to and from the extraction control and/or hob control .
In an advantageous embodiment the combination appliance comprises one or more measuring element and wherein the measuring element is capable of detecting at least one parameter value of the cooking hob and/or the extraction device , wherein the interface unit is capable of processing said parameter value . A measuring element is preferably a timer and/or a sensor, for example temperature sensor, humidity sensor, pot detection sensor, food sensor, RPM sensor, wherein RPM stands for revolutions per minute , photo-optical sensor, piezoelectric sensor, weight sensor, vibration sensor, ultrasonic sensor, water level sensor, and so on . The measuring element is connected to the control module of the combination appliance , preferably the interface unit and/or the extraction control and/or the hob control of the control module . For example , the control module , especially one component of the control module , preferably the interface unit or extraction control or hob control , will receive parameter values from one or more measuring elements . These said parameter values will be converted and/or processed by the interface unit in signals and transmitted to the extraction control . In response to said received signals of the interface unit the extraction control controls and, i f necessary, adj usts at least one of the operation parameters of the extraction device , for example increasing or decreasing the power level of the fan or increasing or decreasing the speed of the fan or switching the fan on or of f .
The at least one measuring element is part of the combination appliance , for example a part of the cooking hob or the extraction device , or is an element , which is arranged outside of the combination appliance and wireless connected to the control module of the combination appliance , for example like a food sensor .
Preferably the parameter values of the measuring elements are selected from the group comprising the temperature , the heat output density of a heating zone , the detection of one or more pots , voltage , frequency, current , humidity value , time and/or flame- si ze .
Furthermore , a preferred embodiment of the inventive combination appliance is characteri zed in that at least one of the operation parameters of the extraction device , preferably the rotational speed of the fan or the power level of the fan or the suction capacity of the fan, is controlled based on at least one of the parameter values of the at least one measuring element , preferably the temperature and/or the heat output density of a heating zone and/or the detection of cookware and/or time . For example , the extraction control of the extraction device increases or decreases the power level of the fan in accordance to the measured temperature of the heating zone of the cooking hob and the detection of a cookware . In another example the extraction control of the extraction device activates the fan of the extraction device after a cookware has been detected on at least one of the heating zones of the cooking hob and the power level of the heating zone of the cooking hob has been set to a high level , wherein high level is understood as every heat output that is above the average heat output of the heating zone , for example power level 5 out of 9 .
Further the setting of operation parameters of the extraction device is preferably also controlled based on the parameter value time . The time is understood as time related to the operation parameters of the cooking hob or related to the measuring elements . For example , time can be measured according to how long the power level or the heat output of the heating zone of the cooking hob has been switched on or has been activated and/or how long has the measuring element measured one of the parameter values . For example , the power level of the heating zone of the cooking hob was set to 9 out of 9 power levels . Therefore , the extraction control of the extraction device activates the at least one fan within seconds and/or minutes , for example to a power level of the fan 4 out of 4 . There can be a time delay between heating a heating zone of the cooking hob and activating the fan of the extraction device or between cooling down a heating zone of the cooking hob and decreasing or deactivating the fan of the extraction device . For example , i f the power level of the cooking hob is turned low or of f , the power level of the fan will be decreased after a predetermined time , which is set by the interface unit , or after another parameter value is measured, for example with a humidity sensor or with a food sensor .
Additionally or alternatively the parameter values of a humidity sensor and/or a vibration sensor and/or a food sensor during a cooking process are measured . These measured parameter values , for example detection of cooking vapours and/or detection of boiling or simmering of the heated food products and/or liquids in the cookware and/or detection of the temperature of the food products and/or liquids , are considered in controlling the fan of the extraction device . For example the fan of the extraction device will be activated as soon as the boiling or simmering of the food products and/or liquids , and/or cooking vapours and/or high temperatures in the food products and/or liquids are detected . High temperatures are understood as temperatures , that are causing cooking vapours , preferably 100 ° C and above .
In another preferred embodiment the interface unit comprises a storage for data, preferably reference data and/or user settings and/or default settings . This means that data, preferably default settings , preferably factory settings , is stored in the interface unit . Factory settings can preferably also include settings for cooking recipe and/or settings for food products , for example boiling water, cooking potatoes , frying a steak, etc . This means that the operation parameters of the cooking hob and the extraction device are being set and/or changed by the user only by choosing from cooking recipes or food products , that are stored in the storage of the interface unit . Alternatively or in addition the received actual parameter values from the measuring elements and/or from the extraction device and/or from the cooking hob are compared to the stored data . Due to deviations of the actual received parameter values in comparison with the stored data, the information will be processed in a signal , that is being transmitted to the extraction control . This signal causes the extraction control to adj ust at least one of the operation parameters of the extraction device according to the result of the comparison of the received actual values with the stored data . Preferably, factory settings are stored in the interface unit . A factory setting could be for example , i f the power level of one heating zone is increased to its maximum, the power of the fan of the extraction device is turned on and increased over a predetermined time also to its maximum power level . This means that factory settings for often used use cases could be stored in the interface unit .
In another preferred embodiment the control module comprises an user interface , wherein the control module , preferably the interface unit and/or hob control and/or extraction control and/or the user interface , comprises at least one receiver unit , wherein the receiver unit is capable of receiving voice commands , especially from the user . This means that the input and/or commands from the user can be transmitted via voice and/or touch . The said user interface preferably is capable of controlling the extraction control and/or the hob control of the combination appliance . The connection between the user interface and the other elements of the control module of the combination appliance are wireless and/or with wiring . The receiver unit is preferably integrated in the control module of the combination appliance , for example integrated in the interface unit and/or extraction control and/or hob control and/or user interface , wherein the said receiver unit may alternatively or additionally be arranged at an external device , for example an external server, preferably a part of a smart home system, such as Google Home®, Amazon Echo®, Apple Homepod® or the like , and/or a computer device and/or a mobile device , such as a tablet or mobile phone , which is detached from the combination appliance . Also the user interface may be arranged at an external device , for example a tablet or mobile phone .
The voice commands from the user are received, processed and transmitted to the extraction control , wherein the extraction control selects operation parameters , for example activating or deactivating the fan, or adj usts the operation parameters , for example increasing or decreasing the power level of the fan . Preferably the control module , especially the interface unit and/or the extraction control and/or the hob control , prioriti zes the users input . This means that the user input will be executed directly without considering other collected information from measuring elements , or stored settings or alike . I f the user wants the combination appliance to interact again automatically, a command has to be sent to the control module of the combination appliance . Preferably said command is entered for example via a touch button on the user interface , which would transmit this command to the interface unit of the combination appliance , and/or via a voice command, which the receiver unit receives and sends to the control module and/or the interface unit and/or the user interface and/or hob control and/or extraction control .
Preferably the user interface comprises an on/of f selection element for activating or deactivating the automatic interaction between the components of the control module of the combination appliance , especially the interaction between the interface unit and the extraction device . In another preferred embodiment user settings of the operation parameters related to the hob control and the extraction control may be saved in the storage of the interface unit . These settings can be saved and/or changed in the interface unit of the control module via touch or voice by the user . The user settings have preferably priority over the other collected, stored, compared and/or processed data and/or parameter values . This means that default settings and/or saved settings regarding the operation parameters of the extraction control may be adj usted by the user . The selections and/or changes of the operation parameters are preferably done by touching the corresponding tool , for example the user interface of the extraction device , or alternatively selecting and/or changing the operation parameters of the extraction device with the voice of the user . Therefore , all users can save their favorite use cases , so that their combination appliance is customi zed
In another preferred embodiment the control module of the combination appliance is coupled with at least one illumination device , wherein the illumination device comprises at least one or more light sources and wherein the illumination device is arranged in the area of the recess . Thereby the illumination of the illumination device indicates the use of the extraction device . Therefore , the illumination device is coupled with the control module , preferably with the extraction control , of the combination appliance . The area of the recess is understood to be the surface of the support surface of the cooking hob from which air can be extracted during maximum fan operation . This means in other words , that the area of the recess comprises at least the area of the support surface between the outer lines of the heating zones of the cooking hob, the recess itsel f and/or the lid, which covers the recess . This means that the illumination device is arranged at a part of the combination appliance , so that the illumination of the illumination device is visible to the user . Preferably, at least one illumination device is arranged at the support surface and/or at the recess and/or at the lid of the combination appliance . The light sources of the illumination device are preferably light-emitting diodes ( LEDs ) . Furthermore , each of the light sources of the illumination device are controllable . This means that the light parameters of each light source of the illumination device can be controlled independently of each other .
Preferably, the control module is capable of controlling at least one light parameter of each light source of the illumination device , preferably activating/deactivating the light source , light intensity and/or light color, as a function of time . This means that the control module of the combination appliance controls each light source of the illumination device . All the data, that is being received by the control module , preferably by the interface unit , especially the operation parameters from the extraction device and/or the cooking hob and/or the parameter values of one or more measuring elements , can indicate changing one or more light parameters of each light source of the illumination device over the time .
In another preferred embodiment one operation parameter of the extraction device , preferably the power level of the extraction device or the rotational speed of the fan, is indicated at the illumination device by changing one or more light parameters over time . This means that the control of the light sources of the illumination device is related to an operation parameter of the extraction device . For example i f the power level of the fan or the rotational speed of the fan is increasing or decreasing, the light sources of the illumination device are changing the color and/or changing the light intensity, so that the light sources get brighter or darker, and/or the light sources are activated and deactivated . The light parameters of each light source can be changed individually or simultaneously . Simultaneously means that all light sources are changing the light parameters at the same time . For example , all light sources are switched on or increasing/decreasing the light intensity or changing the color at the same time . Individually means that all the light sources are controlled in a way, that at least partially the light parameters of the light sources di f fer from each other . For example , moving lights could be visuali zed i f the adj acent light sources change at least one light parameter during a speci fied time period . For example , the power level of the extraction device or the rotational speed of the fan indicates a time period, in which all the light sources are switched on and a time period in which all the light sources are switched of f . The time period of each adj acent light source starts successively, means one after the other, so that the light is visuali zed as a moving light . This predefined time period will be repeated as long as the operation parameter of the extraction device is not changed .
Additionally or alternatively to the operation parameter of the extraction device , one operation parameter of the cooking hob, for example selection of one heating zone , indicates changes of one or more light parameters over the time at the illumination device . This means that the control of the light sources of the illumination device can also be related to an operation parameter of the cooking hob . For example , only light sources that are arranged close to the turned on heating zones are changing at least one light parameter over the time . Therefore , the light parameters of each light source can change according to the description above , but i f more than one operation parameter and/or parameter values are considered, the light parameters of the light sources may change only partially . For example , only the light sources that are arranged directly adj acent to a turned on heating zone or to a detected cookware are switched on, so that the light parameters in this region of the illumination device will indicate one operation parameter of the extraction device as described above .
Furthermore at least one part of the extraction device includes a sound-absorbing material . An example for a sound-absorbing material is glass fiber . The average sound-absorbing coef ficient of a sound-absorbing material is preferably at least 0 , 8 up to 1 , 0 . Preferably one part of the fan of the extraction device of the combination appliance comprises a sound-absorbing material .
Furthermore at least one component of the extraction device comprises an anti-bacterial material . The anti-bacterial material is to be understood as a material , that is toxic for organic li fe and therefore germicidal . This means that the anti-bacterial material has antiseptic properties . For example , components of the extraction device are coated with a layer or made of anti-bacterial material . An example for an anti-bacterial material is copper, silver, enamel and functionali zed sol-gel systems .
The present invention includes also the use of the combination appliance , according to the description above , as an air filter . This means that the extraction device of the inventive combination appliance can filter pollen, fine dust and unpleasant odors , preferably using only the extraction device of the combination appliance . This means that the extraction device can be turned on independent from the use of the cooking hob of the combination appliance .

On the other side of the liquid collector 14 at least one extraction control 18 , for controlling at least one operation parameter of the extraction device 3 , is arranged directly underneath the housing 5 of the cooking hob 2 in a separate extraction control housing 19 .
The recess 11 is covered with a removable lid 20 , wherein in this embodiment the lid 20 is designed as a grid with fluid guiding means 21 . The lid 20 is flush mounted with the upper surface of the support surface 4 , so that moving the cookware from one heating zone to another on the support surface 4 of the cooking hob 5 is possible without li fting the cookware .
In the first embodiment according to Fig . 1 to 3 an illumination device 22 is arranged underneath the support surface 4 around the recess 11 . The illumination device 22 comprises more than one light source 23 , wherein each light source 23 is capable to change one or more light parameters individually from each other and all light sources 23 are preferably light emitting diodes . The light sources 23 are arranged at least in one line around the rectangular recess 11 . This means that it is also possible to have more than one line 24 of light sources 23 arranged around the recess 11 . In this embodiment there are three light source lines 24 , 25 , 26 arranged directly adj acent besides each other and around the recess 11 . In a first option according to this design of the illumination device 22 the light parameters of the light sources 23 can be controlled accordingly to the sucked in air through the recess 11 as i f the lights are also sucked in . The outer light source line 24 , means the light sources 23 furthest away from the recess 11 , are switched on first , then the adj acent second light source line 25 is switched on and the first light source line 24 is switched of f . Afterwards the third light source line 26 , which is adj acent to the second light source line 25 is switched on, and the second light source line 25 is switched of f . This will be repeated again as long as the extraction device 3 , especially the fan 15 of the extraction device 3 , is turned on . The on- and of f-time period of each light source line 24 , 25 , 26 is in accordance with the power level of the fan 15 . This means , the higher the power level and/or the faster the rotational speed of the fan 15 is , the shorter is the time period of the successively switched on light sources 23 of each light source line 24 , 25 , 26 .
In a further option according to this design of the illumination device 22 the light parameters of the light sources 23 can be controlled in a way, that the light sources 23 indicate the rotational speed of the fan 15 . This means that the light sources 23 are switched on/of f in a way, that the switched-on light sources 23 are moving around the recess 11 in a predetermined time period . Therefore , the adj acent light sources 23 are successively switched on and of f again . Additionally, the light source lines 24 , 25 , 26 can be coupled to the power level of the fan 15 of the extraction device 3 , so that at power level one of the fan 15 only the light parameters of the light sources 23 of the light source line 26 , which is the closest to the recess 11 , are being changed . At the power level two of the fan 15 the adj acent light source line 25 is being simultaneously controlled with the inner light source line 26 . This indicates to the user that the fan has actually more power . The third light source line 24 will be controlled simultaneously with the other light source lines 26 , 25 , i f the power level of the fan 15 is increased to the next power level .
Of course , all of these options are also only partially possible regarding the control of the illumination device 22 , so for example only on the side where the heating zone 12 is activated or cookware is detected, the light sources 23 are controlled in such a way as described above . Furthermore , all of these described options are also usable alternatively or additionally in regard to the other light parameters , like light intensity and/or light color . For example , additionally to the options described above , the color of the light sources 23 may change and/or the intensity of the light sources 23 may change in accordance with the power level of the fan 15 . In regard to the light parameter intensity, it is for example possible to control the light sources 23 in such a way, that the light sources 23 are displayed brighter or darker the higher the power level of the fan 15 is . In regard to the light parameter color of the light sources 23 , it is possible to change the color of the light sources 23 according to the power level of the fan 15 . For example , the light sources 23 are colored red for a high power level and blue for a low power level . In Fig . 4 another embodiment of a combination appliance 1 is shown, wherein the only di f ference to the first embodiment in Fig . 1 to Fig . 3 is the arrangement of the illumination device 22 . Here the illumination device 22 is arranged at the inside of the recess 11 . The light sources 23 of the illumination device 22 are arranged at least in one hori zontal line , which is going around the inner surface of the recess 11 . In this embodiment the illumination device 22 comprises an arrangement of the light sources 23 in a matrix form . This means that more than one horizontal line 27 of light sources 23 is arranged at the inner surface of the recess 11 . The light sources 23 can be controlled as described in the embodiment before , wherein at least one light parameter changes according to one operation parameter of the extraction device 3 and/or cooking hob 2 . Preferably the light sources 23 indicate the power level of the fan 15 or the rotational speed of the fan 15 while changing at least one light parameter over the time . For an example the light sources 23 are controlled accordingly to the sucked in air through the recess 11 as i f the illumination is also sucked in . This means that the light sources 23 arranged at the closest to the edge of the support surface 4 are switched on at first . After that the adj acent light sources 23 in the downstream direction of the recess 11 are switched on and the light sources 23 at the edge are switched of f . This successively switching on and of f of the light sources 23 in accordance to the vertical direction of the combination appliance 1 visuali zes the user that the air is sucked in the recess 11 and illustrates moving lights . Also the other described option of controlling the illumination device 22 as described in the first embodiment with the illumination that is running around the recess 11 can be trans ferred to this embodiment . Fig . 5 illustrates another inventive embodiment of a combination appliance 1 , wherein the only di f ference to the other two described embodiments is the arrangement of the illumination device 22 . Here the illumination device 22 is arranged in the lid 20 . Therefore , the lid 20 comprises several light sources 23 , which are arranged at the lid 20 . Preferably the light sources 23 are arranged at the top and/or at the fluid guiding means 21 and/or at the sides of the lid 20 . The illumination device 22 can also be controlled as described in the embodiments before .
Alternatively, it is also possible , that more than one illumination device 22 is arranged at the inventive combination appliance 1 . In Fig . 6 three illumination devices 22 are arranged at the combination appliance 1 , wherein the first illumination device 22 is arranged adj acent to the recess 11 below the support surface 4 . Furthermore , the second illumination device 22 is arranged at the lid 20 . The third illumination device 22 is arranged inside of the recess 11 . In that sense all the three embodiments described above are integrated in one embodiment . All three illumination devices 22 are capable of being controlled together, but each light source 23 is controllable individually . For example , the described above options of controlling the illumination devices 22 can be coupled together so that the light sources 23 on the support surface 4 start and then seamlessly goes over to the light sources 23 of the lid 20 and to the light sources 23 at the recess 11 . Therefore , the light sources 23 of each illumination device 22 extends the lighting ef fect .
All these described options how the illumination device 22 can be controlled, are showing the user directly, on what power level the fan 15 is currently set .
Fig . 7 to Fig . 9 illustrate schematic embodiments of the setup of a control module 28 of the inventive combination appliance 1 .

Therefore , the combination appliance 1 comprises for each heating zone 12 one temperature sensor . Other examples for measuring elements 30 are a pot detecting sensors and/or vibration sensors for detecting boiling of the cookware ingredients , which are also arranged at the cooking hob 2 . Examples for measuring elements 30 , which are arranged at the extraction device 3 , are humidity sensors , that can be arranged at the recess 11 , RPM sensors , that measures the speed of the fan 15 and/or water level sensor, that discloses the fill level of spilled liquid, which is collected in the liquid collector 14 . Further examples for measuring elements 30 are weight sensors , photo-optical sensors , piezoelectric sensors , ultrasonic sensors , food sensors and/or a timer . Some of these parameter values have to be compared related to time . Therefore , also time is being measured by a measuring element 30 .
The information or data that is being received by the measuring elements 30 are transmitted to the interface unit 29 . Furthermore , all the information and/or data from the hob control 6 and/or extraction control 18 are also transmitted to the interface unit 29 . The interface unit 29 processes all of this information or data and sends a signal to the extraction control 18 . The extraction control 18 responses to this received signal from the interface unit 29 by controlling the extraction device 3 accordingly . Controlling the extraction device 3 is understood especially as selecting and/or changing operation parameters of the extraction device 3 , wherein these operation parameters are preferably coupled to the light parameters of the illumination device 22 .
The interface unit 29 comprises a storage 31 for data, that is being collected and/or that has been saved there as reference data and/or user settings and/or default settings . Furthermore , the inventive combination appliance 1 , especially the control module 28 comprises an user interface 32 . The user interface 32 comprises at least one receiver unit , wherein the receiver unit is capable of receiving voice commands , especially from the user . The receiver unit is preferably integrated in the control module 28 of the combination appliance 1 , for example integrated in the interface unit 29 and/or extraction control 18 and/or hob control 6 and/or user interface 32 , wherein the said receiver unit is alternatively or additionally arranged at an external device . The user interface 32 is capable of controlling the extraction control 18 and/or the hob control 6 of the combination appliance 1 .
In Fig . 8 and Fig . 9 the schematic setup of the control module
