Description

Combined device and use thereof

The present invention relates to a combination according to the preamble of claim 1. The invention further relates to the use of a combination according to claim 15.

In household appliances, there is a trend to combine a cooking hob unit with a suction hood to suck in air and cooking vapours downwards. These combined appliances usually have one hole on the supporting surface of the cooking hob and at least one fan for drawing air above the cooking hob. Examples of such appliances are disclosed in document DE 20 2011 005 698 U1 or document EP 3 511 633 A2.

It is an object of the present invention to provide a combination appliance with improved user friendliness and/or user convenience, in particular to be able to use an extraction device in accordance with a cooking hob.

The object of the combination according to the preamble of claim 1 is achieved by the features of the characterizing part of claim 1.

Advantageous alternative embodiments of the invention are partly or completely derived from the dependent claims.

According to the present invention, a combination appliance comprises: a cooking hob including at least one support surface and at least one recess formed in the support surface; and at least one extraction device arranged below a support surface of the cooking hob and comprising at least one fan for drawing air from a space above the cooking hob through a recess of the support surface; and at least one cover for the recess. This means that the combined appliance is a cooking hob with at least one integrated extraction device.

A support surface of a cooking hob is understood to be a carrier plate for cookware, such as pots or pans. Preferably, the support surface is made entirely or partially of glass-ceramic.

The at least one recess arranged in the support surface of the cooking hob is understood to be an opening on the support surface which allows fluid (e.g. liquid and/or air) to pass through to the at least one extraction device.

The cooking hob comprises one or more heating zones, wherein each heating zone is provided with at least one heat transfer element, such as a radiant heater, an induction coil or a gas burner. Preferably, the cooking hob is a gas cooking hob, an induction cooking hob or a radiation cooking hob.

Furthermore, the combination device comprises at least one cover for the recess, wherein preferably the cover is partially or completely arranged or inserted in the recess. The cover is preferably mounted flush with the support surface. The lid is designed as a grid with fluid guiding means or as a cover which completely or only partially closes the recess. A grid is understood to be a cover having openings, wherein the openings are designed to guide a fluid. Preferably, the cover may be made in one or more pieces.

The at least one extraction device is arranged below a support surface of the cooking hob, preferably below the entire cooking hob, wherein below is understood as a direction according to the generally built-in direction of the combined appliance. Furthermore, the fan of the extraction device is able to draw air above the support surface to the fan through the recess. The sucked air will preferably flow through the piping and/or duct system and will then be released through the opening or inside the cabinet.

The combination appliance of the invention is characterized by at least one control module. The control module includes at least one extraction control that controls at least one operating parameter of the extraction device. Further, the control module includes at least one cooktop control that controls at least one operating parameter of the cooking cooktop. Further, the control module comprises at least one interface unit connected to at least the extraction control and the hob control, wherein the interface unit is capable of sending a signal to the extraction control, wherein the extraction control controls the extraction device in response to the signal received from the interface unit.

This means that at least one of the operating 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 controllable and/or preferably controlled based on at least one of the operating parameters of the cooking hob.

The operating parameters of the extraction device are for example configured as a selection and/or a change of the fan and/or the fan power level, and/or a setting of the suction capacity and/or the rotational speed of the fan. This means that if the extraction device comprises more than one fan, preferably each fan can be selected separately, and this selection of fans can be varied. Additionally or alternatively, the previous selection of fans may be changed, wherein each fan may be changed individually. Additionally or alternatively, the power level of each fan may be varied. If the extraction device includes more than one fan, the power levels of the fans may be varied individually, or the power levels of all fans may be varied simultaneously. In other words, the power level of more than one fan may be varied individually or simultaneously, wherein simultaneously means that the power level of each fan is increased and/or decreased to the same power level, or increased and/or decreased at the same level depending on the previous power level of each fan. This means that simultaneously changing the power level of the fans may be to reduce or increase the power level of each fan to one or more power levels that are higher or lower so that the fans still have different power levels, or to reduce and/or increase the power level of each fan so that the fans have the same power level. Additionally or alternatively, the suction capacity of one or more fans may be adjusted. If the extraction device comprises more than one fan, the suction capacity of each fan can be adjusted individually or simultaneously. At the same time, it is intended to increase and/or decrease the suction capacity of each fan to the same suction capacity, or to increase or decrease the suction capacity by the same value depending on the previous suction capacity of each fan, so that the fans still have different suction capacities from one another. Additionally or alternatively, the rotational speed of the fan, preferably of the fan impeller, may be adjusted. If the extraction device comprises more than one fan, the speed of each fan may also be adjusted individually or simultaneously. At the same time, the rotational speed of each fan is increased and/or decreased to the same rotational speed, or increased or decreased by the same value depending on the previous rotational speed of each fan, so that the fans still have different rotational speeds.

The operating parameters of the cooking hob are for example configured as a selection and/or a change of the heating zone, and/or a setting of the heat output and/or the heat output density and/or the power level of the heating zone. This means that each heating zone of the cooking hob can be selected and the selection of the heating zone can be varied. The heating zones of a cooking hob may be selected and/or changed individually or simultaneously. By this is meant that at least two heating zones can be selected at the same time and/or the selection of the at least two heating zones can be changed. The heat output and/or heat output density and/or power level of each heating zone may be adjusted individually or simultaneously. For example, the heat output and/or heat output density and/or power level of each heating zone may be adjusted separately. In addition, the heat output and/or heat output density and/or power level of each heating zone may be adjusted simultaneously, wherein simultaneously is understood to increase and/or decrease the heat output and/or heat output density and/or power level of each heating zone to the same heat output and/or heat output density and/or power level of each heating zone or by the same value, such that the heating zones of the cooking hob still have different heat outputs and/or heat output densities and/or power levels.

Preferably, the operating parameters of the extraction device and/or the cooking hob are selected from the group comprising: selection and/or change of a fan, adjustment of a fan power level, rotation speed of a fan (preferably rotation speed of a fan impeller), suction capacity of a fan, intermittent operation of an extraction device, power level of a heating zone of a cooking hob, selection and/or change of a heating zone of a cooking hob, heat output density of a heating zone of a cooking hob.

The interface unit is a communication device between the extraction control and the hob control. The interface unit is particularly configured to communicate with the extraction control and the hob control by a wireless connection and/or a wired connection. This means that the interface unit is connected on the one hand to the extraction control, and on the other hand to the hob control, either wired or wireless. The interface unit is preferably a data processing unit in which data is processed and/or executed, operations are transformed, transmitted and/or stored. In other words, the interface unit preferably receives, transforms, stores, transmits and/or executes data. Furthermore, the interface unit is preferably integrated in and/or a part of the extraction control, or in and/or a part of the hob control. This means that the interface unit is preferably arranged in the combined appliance. Alternatively, the interface unit may be arranged at an external device (e.g. an external server, preferably such as Google)

Amazon/>

Apple/>

Etc.) and/or at a computer device and/or mobile device (such as a tablet or mobile phone) separate from the combination appliance. In this case, the interface unit is configured to communicate with the extraction control and/or the hob control over a wireless connection.

In an advantageous embodiment, the combined appliance comprises one or more measuring elements, and wherein the measuring elements are 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. The measuring element is preferably a timer and/or a sensor, such as a temperature sensor, a humidity sensor, a pot detection sensor, a food sensor, an RPM sensor (where RPM stands for revolutions per minute), a photoelectric sensor, a piezoelectric sensor, a weight sensor, a vibration sensor, an ultrasonic sensor, a water level sensor, etc. The measuring element is connected to a control module of the combined appliance, preferably to an interface unit and/or an extraction control and/or a hob control of the control module. For example, the control module (in particular a component of the control module, preferably an interface unit or an extraction control or a hob control) will receive parameter values from one or more measurement elements. These values of said parameters are converted and/or processed into signals by the interface unit and transmitted to the extraction control. In response to said received signal of the interface unit, the extraction control controls and, if necessary, adjusts at least one of the operating 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 turning the fan on or off.

The at least one measuring element is part of the combined appliance (e.g. is part of a cooking hob or extraction equipment) or is an element arranged outside the combined appliance and wirelessly connected to a control module of the combined appliance (e.g. like a food sensor).

Preferably, the parameter value of the measuring element is selected from the group comprising: temperature, heat output density of a heating zone, detection of one or more pots, voltage, frequency, current, humidity value, time, and/or flame size.

Furthermore, a preferred embodiment of the combination of the invention is characterized in that at least one of the operating 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 on the basis of at least one of the parameter values of the at least one measuring element (preferably the temperature and/or the heat output density of the heating zone and/or the detection of the cookware and/or the time). For example, the extraction control of the extraction device increases or decreases the power level of the fan depending on the measured temperature of the heating zone of the cooking hob and the detection of the cookware. In another example, after cookware is detected on at least one heating zone of the cooking hob and the power level of the heating zone of the cooking hob has been set to a high level, which is understood to be each heat output above the average heat output of the heating zone, e.g. a power level of 5 out of 9 power levels, the extraction control of the extraction device activates the fan of the extraction device.

Further, the setting of the operating parameters of the extraction device is preferably also controlled on the basis of the parameter value time. This time is understood to be the time related to an operating parameter of the cooking hob or related to the measuring element. For example, the time may be measured depending on how long the power level or heat output of a heating zone of the cooking hob has been switched on or has been started and/or how long the measuring element has measured one of the parameter values. For example, the power level of the heating zone of the cooking hob is set to a power level 9 out of 9 power levels. Thus, the extraction control of the extraction device activates the at least one fan, for example to a power level 4 among the 4 power levels of the fan, within seconds and/or minutes. There may be a time delay between heating the heating zone of the cooking hob and activating the fan of the extraction device, or between cooling the heating zone of the cooking hob and lowering or deactivating the fan of the extraction device. For example, if the power level of the cooking hob is turned down or off, the power level of the fan will be reduced after a predetermined time set by the interface unit or after measuring another parameter value, e.g. with a humidity sensor or a food sensor.

Additionally or alternatively, parameter values of a humidity sensor and/or a vibration sensor and/or a food sensor are measured during the cooking process. These measured parameter values are taken into account when controlling the fan of the extraction device, for example the detection of cooking vapours and/or the detection of boiling or simmering of heated food and/or liquid in a cooker and/or the detection of the temperature of food and/or liquid. For example, upon detecting boiling or simmering of the food product and/or liquid, and/or high temperature of the cooking vapor, and/or food product and/or liquid, the fan of the extraction device will be activated. High temperature is understood to be the temperature that causes cooking vapours, preferably 100 ℃ and above.

In another preferred embodiment the interface unit comprises a memory for data, preferably reference data and/or user settings and/or default settings. This means that data, preferably default settings, preferably factory settings, are stored in the interface unit. The factory settings may also preferably include settings for cooking recipes and/or settings for food products, such as boiling water, cooking potatoes, frying steaks, etc. This means that the user sets and/or changes the operating parameters of the cooking hob and the extraction device only by selecting from cooking recipes or food products stored in the memory of the interface unit.

Alternatively or additionally, the actual parameter values received from the measurement element and/or from the extraction device and/or from the cooking hob are compared with stored data. Since the actual received parameter values are biased compared to the stored data, the information will be processed into a signal which is transmitted to the extraction control. The signal causes the extraction control to adjust at least one of the operating parameters of the extraction device in accordance with the result of the comparison of the received actual value with the stored data. Preferably, the factory settings are stored in the interface unit. For example, the factory setting may be that if the power level of one heating zone is increased to its maximum, the power supply of the fan of the extraction device is turned on and also increased to its maximum power level within a predetermined time. This means that the factory settings of the commonly used cases can be stored in the interface unit.

In another preferred embodiment, the control module comprises a user interface, wherein the control module (preferably the interface unit and/or the hob control and/or the extraction control and/or the user interface) comprises at least one receiver unit, wherein the receiver unit is capable of receiving voice commands, in particular from a user. This means that input and/or commands from the user can be transmitted via speech and/or touch. The user interface is preferably capable of controlling an extraction control and/or a cooktop control of a combination appliance. The connections between the user interface and the other elements of the control module of the combination appliance are wireless and/or wired. The receiver unit is preferably integrated in the control module of the combined appliance, e.g. in the interface unit and/or the extraction control and/or the hob control and/or the user interface, wherein the receiver unit may alternatively or additionally be arranged in an external device (e.g. an external server, preferably such as Google @)

Amazon

Apple/>

Etc.) and/or at a computer device and/or mobile device (such as a tablet or mobile phone) separate from the combination appliance. Also, the user interface may be disposed at an external device (e.g., a tablet or a mobile phone).

Voice commands from a user are received, processed, and transmitted to the extraction control, where the extraction control selects an operating parameter (e.g., activates or deactivates a fan) or adjusts an operating parameter (e.g., increases or decreases a power level of a fan). Preferably, the control module (in particular the interface unit and/or the extraction control and/or the hob control) prioritizes the user input. This means that the user input will be performed directly without taking into account other information collected from the measuring elements or stored settings etc. If the user wishes the combination appliance to automatically interact again, a command must be sent to the control module of the combination appliance. Preferably, said command is for example input via a touch button on the user interface which transmits the command to the interface unit of the combined appliance, and/or said command is input via a voice command which is received by the receiver unit and sent to the control module and/or the interface unit and/or the user interface and/or the hob control and/or the extraction control.

Preferably, the user interface comprises an on/off selection element for activating or deactivating an automatic interaction between the components of the control module of the combined appliance, in particular the interaction between the interface unit and the extraction device.

In another preferred embodiment, user settings of operating parameters related to the hob control and the extraction control may be saved in a memory of the interface unit. The user can save and/or change these settings in the interface unit of the control module via touch or voice. The user setting preferably overrides other collected, stored, compared and/or processed data and/or parameter values. This means that default settings and/or saved settings for the operating parameters of the extraction control can be adjusted by the user. The selection and/or changing of the operating parameters is preferably done by touching a corresponding tool (e.g. a user interface of the extraction device), or alternatively by a user's voice selecting and/or changing the operating parameters of the extraction device. Thus, all users can save their favorite use cases to customize their combined appliances.

In a further preferred embodiment, the control module of the combination appliance is coupled with at least one lighting device, wherein the lighting device comprises at least one or more light sources, and wherein the lighting device is arranged in the region of the recess. Thereby, the illumination of the illumination device indicates the use of the extraction device. The lighting device is therefore coupled to the control module of the combination appliance, preferably to the extraction control. The area of the recess is understood to be the surface of the support surface of the cooking hob from which air can be drawn during maximum operation of the fan. In other words, this means that the area of the recess comprises at least the area of the support surface between the outer line of the heating zone of the cooking hob, the recess itself and/or the cover covering the recess. This means that the lighting device is arranged at a part of the combination fixture such that the illumination of the lighting device is visible to the user. Preferably, the at least one lighting device is arranged at a support surface and/or a recess and/or a cover of the combination appliance. The light source of the lighting device is preferably a Light Emitting Diode (LED). Furthermore, each of the light sources of the lighting device is controllable. This means that the light parameters of each light source of the lighting 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 lighting device, preferably activating/deactivating the light source, the light intensity and/or the light color in dependence of time. This means that the control module of the combined fixture controls each light source of the lighting device. All data received by the control module (preferably by the interface unit), in particular the operating parameters from the extraction device and/or the cooking hob, and/or the parameter values of the one or more measurement elements, may indicate the variation over time of the one or more light parameters of each light source of the lighting device.

In another preferred embodiment, one operating parameter of the extraction device (preferably the power level of the extraction device or the rotational speed of the fan) is indicated at the lighting device by varying one or more light parameters over time. This means that the control of the light source of the lighting device is related to the operating parameters of the extraction device. For example, if the power level of the fan or the rotational speed of the fan is increased or decreased, the light source of the lighting device changes color and/or changes light intensity, causing the light source to become brighter or darker, and/or the light source to be activated and deactivated. The optical parameters of each light source may be varied individually or simultaneously. At the same time, all light sources change the light parameters at the same time. For example, all light sources are turned on or increase/decrease the light intensity or change color at the same time. By individually is meant that all light sources are controlled in such a way: the optical parameters of at least some of the light sources are different from each other. For example, if an adjacent light source changes at least one light parameter during a specified time period, moving light may be seen. For example, the power level of the draw device or the speed of the fan indicates the period of time that all light sources are on and the period of time that all light sources are off. The time period for each adjacent light source starts successively, meaning one after the other, so the light is considered to be moving light. This predefined period of time repeats as long as the operating parameters of the extraction device do not change.

In addition to or as an alternative to the operating parameter of the extraction device, an operating parameter of the cooking hob (e.g. selection of a heating zone) indicates a change of one or more light parameters at the lighting device over time. This means that the control of the light source of the lighting device may also be related to the operating parameters of the cooking hob. For example, only the light source arranged close to the switched-on heating zone changes at least one light parameter over time. Thus, the light parameters of each light source may be varied according to the above description, but may only be partly varied if more than one operating parameter and/or parameter value is considered. For example, only the light source arranged directly adjacent to the opened heating zone or the detected cookware is switched on, so that the light parameter in this area of the illumination device will be indicative of one operating parameter of the extraction device as described above.

Furthermore, at least a portion of the extraction apparatus comprises a sound absorbing material. An example of sound absorbing material is fiberglass. The sound absorbing material preferably has an average sound absorption coefficient of at least 0.8 to 1.0. Preferably, a portion of the fan of the extraction apparatus of the combination appliance comprises sound absorbing material.

Further, at least one component of the extraction device comprises an antimicrobial material. An antimicrobial material is understood to be a material which is toxic to organic life and therefore has a bactericidal effect. This means that the antimicrobial material has antiseptic properties. For example, the components of the extraction device may be coated or made of an antimicrobial material. Examples of antimicrobial materials are copper, silver, enamel and functionalized sol-gel systems.

The invention also includes the use of a combined appliance according to the above description as an air filter. This means that the extraction device of the combined appliance of the invention can filter pollen, motes and bad smells, preferably using only the extraction device of the combined appliance. This means that the extraction device can be opened independently of the use of the cooking hob of the combined appliance.

Fig. 1 to 3 show an embodiment of a combination device 1 according to the invention in different views. The combination appliance 1 comprises a cooking hob 2 and an extraction device 3. The cooking hob 2 comprises a support surface 4 and supports a cookware. This means that the support surface 4 is the surface on which the cookware is placed. The support surface 4 is typically made of glass ceramic. The cooking hob 2 further comprises: a housing 5, wherein the housing 5 encloses two hob controls 6 for controlling at least one operating parameter of the cooking hob 2; and at least one energy transfer element 7, for example, a radiant heater, an induction coil, or a gas burner. The housing 5 is arranged below the support surface 4, wherein below is understood as the direction of the built-in case of a combined appliance.

The cooking hob 2 has a width W _I Height H _I And depth D _I . Width W of the cooking hob 2 _I Measured from one side 8 of the support surface 4 to the other side 8 of the support surface 4. Depth D of the cooking hob 2 _I Measured from the front side 9 to the rear side 10 of the support surface 4. Height H of the cooking hob 2 _I Measured from the upper surface of the support surface 2 to the bottom surface of the housing 5 of the cooking hob 2.

In the illustrated embodiment, the support surface 4 comprises a recess 11 and four heating zones 12. Alternatively, the support surface may comprise two or more recesses, preferably symmetrically arranged on the support surface around the heating zone 12. The recess 11 is according to the width W of the cooking hob 2 _I Arranged in the middle of the support surface 4. The recess 11 is rectangular in shape and is in the height direction H from the upper surface of the support surface 2 to the bottom surface of the housing 5 of the cooking hob 2 _I And an upper extension. The recess 11 is in the depth direction D of the cooking hob 2 _I The upper extension is at least one third of the depth of the support surface 4, preferably at least half the depth of the support surface 4.

The extraction device 3 is arranged directly below the housing 5 of the cooking hob 2. In this embodiment, the extraction device 3 comprises a grease filter 13 and a liquid collector 14 arranged below the recess 11. In this embodiment, the grease filter 13 is arranged in the liquid collector 14. Further, in this embodiment, the extraction device 3 comprises a fan 15, which is arranged beside the liquid collector 14. This means that the fan 15 is arranged at one side of the cooking hob 2. The fan 15 draws air from the space above the cooking hob 2 through the recess 11 of the support surface 4. The air flows through the grease filter 13 and at least one opening 16 in the liquid collector 14, causing an air flow into the fan 15. The fan 15 and the liquid collector 14 are surrounded by an extraction device housing 17.

On the other side of the liquid collector 14, at least one extraction control 18 for controlling at least one operating parameter of the extraction device 3 is arranged in a different extraction control housing 19 directly below the housing 5 of the cooking hob 2.

The recess 11 is covered with a removable cover 20, wherein, in this embodiment, the cover 20 is designed as a grid with fluid guiding means 21. The lid 20 is mounted flush with the upper surface of the support surface 4 such that a cookware is moved from one heating zone to another on the support surface 4 of the cooking hob 5 without lifting the cookware.

In the first embodiment according to fig. 1 to 3, the lighting device 22 is arranged below the support surface 4 around the recess 11. The lighting device 22 comprises more than one light source 23, wherein each light source 23 is capable of varying one or more light parameters independently of 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 arrange more than one line 24 of light sources 23 around the recess 11. In this embodiment, there are three light source lines 24, 25, 26 arranged directly adjacent to each other and around the recess 11. In a first option according to this design of the lighting device 22, the light parameters of the light source 23 can be controlled accordingly in dependence on the air sucked in through the recess 11 as if light is also sucked in. The outer light source line 24 means that the light source 23 farthest from the recess 11 is first turned on, then the adjacent second light source line 25 is turned on and the first light source line 24 is turned off. Thereafter, the third light source line 26 adjacent to the second light source line 25 is turned on, and the second light source line 25 is turned off. This process will be repeated again as soon as the extraction device 3, in particular the fan 15 of the extraction device 3, is switched on. The switching period of each

light source line

24, 25, 26 corresponds to the power level of the fan 15. This means that the higher the power level and/or the faster the speed of rotation of fan 15, the shorter the period of time during which light source 23 of each

light source line

24, 25, 26 is turned on successively.

In a further option according to this design of the lighting device 22, the light parameters of the light source 23 may be controlled in such a way: the light source 23 indicates the speed of rotation of the fan 15. This means that the light source 23 is turned on/off in such a manner: the activated light source 23 moves around the recess 11 for a predetermined period of time. Thus, the adjacent light sources 23 are again turned on and off successively. In addition, the light source lines 24, 25, 26 may be coupled to the power level of the fan 15 of the extraction device 3 such that, when the power level of the fan 15 is one, only the light parameters of the light sources 23 of the light source line 26 closest to the recess 11 are changed. When the power level of the fan 15 is two, the adjacent light source lines 25 and the inner light source line 26 are simultaneously controlled. This indicates to the user that the power of the fan is actually greater. If the power level of fan 15 is increased to the next power level, third light source line 24 will be controlled simultaneously with the other light source lines 26, 25.

Of course, all these options are also only partly feasible in connection with controlling the illumination device 22, so that the light source 23 is controlled in this way as described above, for example only on the side where the heating area 12 is activated or the cookware is detected. Furthermore, all these described options may alternatively or additionally also be used for other light parameters, such as light intensity and/or light color. For example, in addition to the above options, the color of the light source 23 may be changed and/or the intensity of the light source 23 may be changed according to the power level of the fan 15. With regard to the light parameter intensity, the light source 23 may be controlled, for example, in such a way that: the higher the power level of the fan 15, the brighter or darker the light source 23 is displayed. With respect to the light parameter color of the light source 23, the color of the light source 23 may be changed according to the power level of the fan 15. For example, the light source 23 is red in color, indicating a high power level, and blue in color, indicating a low power level.

In fig. 4, a further embodiment of a combination appliance 1 is shown, wherein the only difference from the first embodiment in fig. 1 to 3 is the arrangement of the lighting device 22. Here, the lighting device 22 is arranged inside the recess 11. The light sources 23 of the lighting device 22 are arranged at least on a horizontal line surrounding the inner surface of the recess 11. In this embodiment, the lighting device 22 comprises light sources 23 arranged 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 source 23 may be controlled as described in the previous embodiments, wherein at least one light parameter is varied depending on one operating parameter of the extraction device 3 and/or the cooking hob 2. Preferably, the light source 23 indicates the power level of the fan 15 or the rotational speed of the fan 15 while varying at least one light parameter over time. For example, the light source 23 is controlled accordingly in accordance with the air sucked through the recess 11 as if the illumination is also sucked. This means that the light source 23 arranged at the edge closest to the support surface 4 is turned on first. Thereafter, the adjacent light sources 23 in the downstream direction of the recess 11 are turned on, and the light sources 23 at the edges are turned off. This sequential turning on and off of the light sources 23 according to the vertical direction of the combination 1 allows the user to see that air is drawn into the recess 11 and to show the moving light. Also, the other described options of controlling the lighting device 22, which illuminates the surrounding recess 11 as described in the first embodiment, may be transferred to this embodiment.

Fig. 5 shows a further inventive embodiment of the combination appliance 1, wherein the only difference from the other two described embodiments is the arrangement of the lighting device 22. Here, the lighting device 22 is arranged in the cover 20. Thus, the cover 20 comprises several light sources 23 arranged at the cover 20. Preferably, the light source 23 is arranged at the top and/or at the fluid guiding means 21 and/or at the side of the cover 20. The lighting device 22 may also be controlled as described in the previous embodiments.

Alternatively, more than one lighting device 22 may also be arranged at the combined fixture 1 of the present invention. In fig. 6, three lighting devices 22 are arranged at the combination fixture 1, wherein a first lighting device 22 is arranged adjacent to the recess 11 below the support surface 4. Furthermore, a second lighting device 22 is arranged at the cover 20. A third lighting device 22 is arranged inside the recess 11. In this sense, all three embodiments described above are integrated in one embodiment. All three lighting devices 22 can be controlled together, but each light source 23 is individually controllable. For example, the above options of controlling the lighting device 22 may be coupled together such that the light source 23 near the support surface 4 starts first and then seamlessly transitions to the light source 23 of the cover 20 and the light source 23 at the recess 11. Thus, the light source 23 of each lighting device 22 expands the lighting effect.

All of these described options of how the lighting device 22 may be controlled show the user directly what power level the fan 15 is currently set at.

Fig. 7 to 9 show an exemplary embodiment of the arrangement of the control module 28 of the combined appliance 1 of the invention. The combination appliance 1 of the present invention comprises a control module 28. The control module 28 comprises at least one hob control 6 capable of controlling at least one operating parameter of the cooking hob 2, at least one extraction control 18 controlling at least one operating parameter of the extraction device 3, and one interface unit 29 connected at least to the extraction control 18 and to the hob control 6. The interface unit 29 is able to send a signal to the extraction control 18. This means that the interface unit 29 is a communication device between the extraction control 18 and the hob control 6. The interface unit 29 is in particular configured to communicate with the extraction control 18 and the hob control 6 by a wireless connection and/or a wired connection, wherein the connections between each other are illustrated with lines in fig. 7 to 9. The interface unit 29 may be part of the combination appliance 1 or may be arranged at an external device as shown in fig. 7 (e.g. an external server, preferably such as Google)

Amazon/>

Apple/>

Etc.) and/or arranged at a computer device and/or mobile device (such as a tablet or mobile phone) separate from the combination appliance 1.

Furthermore, a measuring element 30 is coupled to the hob control 6, the extraction control 18 and/or the interface unit 29 for measuring parameter values of the cooking hob 2 and/or the extraction device 3. For example, one measuring element 30 is a temperature sensor, which is arranged at each heating zone 12. The combined appliance 1 therefore comprises one temperature sensor for each heating zone 12. Other examples of measuring elements 30 are pot detection sensors and/or vibration sensors for detecting boiling of ingredients in the cookware, which sensors are also arranged at the cooking hob 2. Examples of measuring elements 30 arranged at the extraction device 3 are a humidity sensor which may be arranged at the recess 11, an RPM sensor which measures the speed of the fan 15, and/or a water level sensor which displays the filling level of overflow liquid collected in the liquid collector 14. Further examples of measuring elements 30 are weight sensors, photoelectric sensors, piezoelectric sensors, ultrasonic sensors, food sensors and/or timers. Some of these parameter values must be compared with respect to time. Thus, the measuring element 30 also measures time.

The information or data received by the measuring element 30 is transmitted to the interface unit 29. Furthermore, all information and/or data from the hob control 6 and/or the extraction control 18 are also transmitted to the interface unit 29. The interface unit 29 processes all this information or data and sends a signal to the extraction control 18. The extraction control 18 responds to this signal received from the interface unit 29 by controlling the extraction device 3 accordingly. Controlling the extraction device 3 is in particular understood as selecting and/or changing operating parameters of the extraction device 3, wherein these operating parameters are preferably related to light parameters of the lighting device 22.

The interface unit 29 comprises a memory 31 for data which is being collected and/or which has been saved in the memory as reference data and/or user settings and/or default settings. Furthermore, the combination appliance 1 of the invention, in particular the control module 28, comprises a user interface 32. The user interface 32 comprises at least one receiver unit, wherein the receiver unit is capable of receiving voice commands, in particular from a user. The receiver unit is preferably integrated in the control module 28 of the combination appliance 1, for example in the interface unit 29 and/or the extraction control 18 and/or the hob control 6 and/or the user interface 32, wherein said receiver unit is alternatively or additionally arranged at the external device. The user interface 32 is capable of controlling the extraction control 18 and/or the hob control 6 of the combined appliance 1.

In fig. 8 and 9, the schematic arrangement of the control module 28 differs from that of fig. 7 only in that: the interface unit 29 is integrated directly in the hob control 6 or in the extraction control 18 and each control module 28 comprises only one extraction control 18 and one hob control 6. Furthermore, in this embodiment, the user interface 32 is integrated in the interface unit 29.
