Description

Technical Field

[0001] The invention relates to a range hood with an operating module. Background Art

[0002] For operating a range hood, operating units are known that include individual operating elements, particularly in the form of buttons, for operating various functional units of the range hood, particularly the ventilation fan or the lighting. These buttons can be designed, for example, as touch sensors integrated into the display. Each button can be assigned a specific function, allowing it to be adjusted by manually actuating the corresponding button or touch sensor. To simplify operation and adjustment, the function of each button is typically identified by an embossed symbol, and these operating elements are typically located within the user's field of vision, for example, on the front of the range hood.

[0003] However, the arrangement within the user's field of vision not only affects the appearance and acceptability of the range hood, but may also have a negative impact on the user when performing further work under the range hood. Therefore, the operating part is preferably arranged out of the user's field of vision after adjustment or after the range hood is operated.

[0004] However, such an out-of-sight arrangement makes it impossible to selectively or specifically select and adjust the corresponding functions. Therefore, the operating element is disconnected to prevent incorrect or unintentional adjustments and must be placed within sight to enable further function adjustment. Furthermore, for function adjustment, the operating element must first be switched on, regardless of its placement. This operating procedure is perceived by the user as cumbersome and unintuitive, particularly when adjusting simple functions, such as operating a light in low light conditions. Summary of the Invention

[0005] It is therefore an object of the present invention to provide a range hood which allows simplified operation and adjustment of the functions of the range hood.

[0006] According to the present invention, this object is achieved by a range hood comprising an operating module, wherein the operating module includes an operating panel for adjusting functions of the range hood coupled to the operating module. The operating panel has at least two areas, and the operating module is configured to adjust at least one specific function of the range hood in a first operating mode of the operating module and upon actuation of a specific area. The range hood is characterized in that the operating module can also be operated in a second operating mode, wherein the operating module is configured to adjust at least one predetermined function of the coupled range hood in the second operating mode and upon actuation of the at least two areas.

[0007] The operating module can be integrated into the range hood or connected to the range hood as a separate component. For example, the operating module can be arranged in a housing of the range hood, which can also be considered the base of the range hood, or can be received in a receptacle of the range hood housing, for example, on the bottom and / or front or side surface of the range hood. The operating module is communicatively coupled to the corresponding components required for the functions, so that the functions of the range hood can be adjusted via the operating panel of the operating module. The operating module can thus be designed as a modular unit that is installed in the range hood as standard or can be coupled to the range hood for retrofitting.

[0008] The operating area defines a section of the operating module, through which a specific function can be adjusted. The different areas can be configured, for example, as correspondingly labeled keys, wherein actuation of the keys generates a signal, such as an electromechanical signal, that is specific to the corresponding function. Thus, manual actuation or contact of the individual areas enables adjustment of the corresponding functions. However, instead of manual input, a pen or similar device can also be provided to allow contact with the corresponding area and adjustment of the corresponding function.

[0009] The function of the range hood is particularly to draw in air, smoke and steam from the space below the range hood and to illuminate the space in particular below the range hood. In addition, the function can include, if necessary, specific operating states under predefined or specific operating conditions.

[0010] Thus, at least one function of the range hood can be at least temporarily implemented, thereby defining an operating state. For example, normal ventilation can be implemented, in which the ventilation level is usually selected or specified by the user. Another operating state is intermittent ventilation, in which the ventilation fan is only operated at timed intervals. Supplementary ventilation also represents an operating state of the range hood. In this case, the ventilation fan continues to operate for a predetermined period of time after the range hood is switched off. In the automatic ventilation operating state, the ventilation power or ventilation level is specified by a sensor signal, for example, detected by an ultrasonic sensor.

[0011] The aforementioned operating states of the range hood all relate to the range hood's function of drawing in air, steam, and vapor. Of course, the range hood can also be placed in other operating states in which the lighting device illuminates a room or surface. The different operating states of the range hood related to the intake of air, steam, and vapor, as well as the operating state of the lighting, can also be adjusted in combination with one another, wherein adjusting a specific function may require multiple actuations of corresponding individual areas of the operating module.

[0012] Furthermore, for each operating state, there may be a plurality of operating conditions, which describe, in particular, the duration and intensity of the functions to be performed by the range hood in this operating state. These operating conditions are, in particular, the ventilation power and / or the intensity of the lighting, the duration of the ventilation and / or lighting, the timing of the ventilation and / or lighting, the generation of sensor signals by sensors, and programs which regulate the operating conditions of further functional units.

[0013] To minimize incorrect or unintentional adjustments, the operating module is configured to determine its operating mode, referred to below for simplicity as the operating mode, and to implement functions dependent on the operating mode. Thus, in the first operating mode described above, specific functions can be adjusted by actuating a single area of ​​the operating panel. In other words, the user can, for example, adjust a specific operating state of the ventilation device by actuating corresponding buttons. Provision can also be made for actuating multiple areas in the first operating mode to produce specific operating states or combinations of functions.

[0014] In the second operating mode, the function is adjusted only when at least two areas are actuated, so actuation of a single area does not result in an adjustment. This has the advantage that in the second operating mode, unintentional contact with a single, specific area does not result in an undesirable adjustment of the corresponding, specific function. Thus, for example, in low light conditions, targeted actuation may be difficult, so that instead of actuating an area specific for light adjustment, an area specific for ventilation system adjustment can be actuated. In such cases, the ventilation system or ventilation system adjustment is advantageously not adapted, and the user does not have to first cancel an unintentional adjustment of a function or have to make multiple attempts to adjust the desired function.

[0015] Furthermore, the functions in the second operating mode are not specific to the first operating mode, but are predetermined. Thus, even in the second operating mode, simple basic functions can be adjusted by manipulating a plurality of areas.

[0016] The predefined functions in the second operating mode preferably include switching the light and / or ventilation on and off, preferably at predefined intensities. For example, by actuating at least two zones, a predefined light intensity of at least one light source of the range hood and / or a predefined ventilation intensity can be adjusted. This allows the user to invoke specific functions of the range hood under different conditions, such as simply implementing a predefined or preset lighting function for the room ambiance or atmosphere, or switching the ventilation system on under predefined operating conditions, if, for example, no specific adjustment of the operating state is required and the standard program is sufficient for working under the range hood.

[0017] Preferably, the first operating mode is normal operation for regulating corresponding specific functions of the coupled range hood, and these functions are at least partially deactivated in the second operating mode. In other words, the first operating mode allows for active and specific regulation of various functions, while this possibility is at least partially absent in the second operating mode. Thus, the first operating mode can correspond to the switched-on state of the operating module, and the second operating mode can be, for example, an idle state, a switched-off state, a standby mode, or a power-saving mode of the operating module and, if applicable, the range hood.

[0018] Furthermore, the provision of predefined functions in the second operating mode has the advantage that the operating module does not need to be switched on or activated in order to implement a specific function of the range hood. As a result, the operating module can continue to operate in the second operating mode, while, for example, still implementing the lighting function as a basic function. This significantly simplifies operation for the operator, as the user does not need to operate either an on button or a specific area, and can easily adjust the predefined function by touching at least two areas.

[0019] By setting up two areas, it is already possible to adjust a variety of predefined functions or to distinguish between a variety of predefined functions, for example by means of different detected operating durations or by means of different detected operating pressures. Similarly, the areas or buttons of the operating area can be separated from each other. However, it is preferred that the operating area includes at least three areas arranged in rows and adjacent to each other. Two or more areas can also be arranged in multiple adjacent rows, so that the areas can be arranged not only in parallel but also one above the other or form a matrix. The operating module can be configured to adjust the predefined functions in the second operating mode without depending on the corresponding functions of the operated areas that are specific to the first operating mode.

[0020] Accordingly, even if a number of areas or buttons are provided for adjusting specific functions in the first operating mode, the user can operate any two areas to adjust the predetermined function. In other words, the operation in the second operating mode is unspecific, and the predetermined function can be adjusted using any combination of two areas. Furthermore, the row-shaped, adjacent arrangement has the advantage that the areas are directly parallel, simplifying the user's operation of the at least two areas, particularly in low light conditions or when the operating area is difficult to access or can only be accessed indirectly.

[0021] Furthermore, the operating module can be configured to adjust a predetermined function as a function of the detected number of actuated areas, the detected order of actuated areas, the detected speed of the order of actuated areas, a specific actuation direction and / or a detected actuation duration.

[0022] In this way, as described above, different predefined functions can be set, for example, by different actuation durations detected by the operating module. Additionally or alternatively, it can also be provided that, if, for example, the user actuates the operating area with three or more fingers instead of two, two or more areas are actuated, wherein, when actuating two areas, for example, a predefined light setting is set, and when actuating three or more areas, for example, a predefined ventilation intensity is set.

[0023] Furthermore, to adjust a predefined function, it may be necessary to manipulate the areas simultaneously. Additionally or alternatively, the predefined function can also be adjusted by manipulating multiple areas in a sequential manner. Thus, a single first area can be manipulated first, and then an adjacent or contiguous second area, without the first area being manipulated or touched again. The operating module is preferably configured to detect the temporal component of the manipulation, so that, for example, a distinction can be made between targeted, continuous, or unintentional manipulation of multiple areas based on the duration of the manipulation of the respective areas and / or the time intervals between manipulations of the respective areas.

[0024] Furthermore, during continuous operation, an operating direction that is characteristic of a predetermined function of the range hood can be detected. During continuous operation, a single area or multiple adjacent areas can be operated in each state, thereby enabling, for example, a wiping movement performed by a user with one or two fingers to be detected or determined. Furthermore, this allows for the detection of a wiping movement at the end areas of the operating area, if, for example, the outer two areas at one end of the operating area are first operated and then only the outermost area is operated, preferably by detecting this based on the duration of the operation.

[0025] This provides the user with various options for adjusting a predetermined function, or even a plurality of different predetermined functions. Advantageously, nearly the entire operating range can be used for this purpose, and the user can adjust simple, basic functions of the range hood without requiring targeted selections or complex operations. Although the aforementioned operating durations and operating sequences allow for a wide range of functions, these different operating modes can also represent a certain redundancy, so that the user does not have to consider the necessary operating modes when adjusting a predetermined function in the second operating mode.

[0026] Furthermore, the operating module is preferably configured to adjust different predefined functions for static and dynamic operation. In other words, the operating module can distinguish between unordered, planar operation and continuous operation, and thus, for example, between the application of a fingertip and a wiping motion. For static, planar operation, it can be provided, for example, that a preset or predefined light intensity of a light source is switched on, while a wiping motion causes a predefined ventilation intensity to be adjusted. By repeating the corresponding operation, the corresponding function can also be switched off, wherein the switching on and off during the wiping motion can be selectively dependent on the detected direction of the operation.

[0027] In order to provide an improved differentiation between the first and second operating modes, the operating module can also be configured to adjust specific functions only when a single, specific area is actuated in the first operating mode. Furthermore, the operating module can automatically switch to the second operating mode after a predetermined time, during which no adjustments are made, in which case only specific, predetermined functions can then be selected or adjusted.

[0028] In such a configuration or design, it can also be provided that predetermined functions provided in the second operating mode can also be adjusted in the first operating mode by operating a plurality of zones. Thus, for example, if the operating module automatically switches to the second operating mode, the light and / or ventilation intensity can be easily controlled without having to switch the operating module to the first operating mode and making a selective, specific selection for the corresponding zones.

[0029] In order to integrate the operating module into the range hood, a communication coupling can be provided. Preferably, the operating module includes a control and regulation unit that is communicatively coupled to the operating panel, or an interface for communicatively coupling the operating panel to the range hood's control and regulation unit, in order to detect manipulation of the zones and adjust the functions. This allows the control and regulation unit to be at least partially relocated, thereby minimizing the complexity of the operating module. In this case, the operating module can transmit electrical signals detected at the operating panel for processing and control / regulation of the functional units of the range hood via corresponding interfaces to a central control and regulation unit. For example, the connection between the operating module and the ventilation fan unit and the lighting unit can be established via a control unit, which can be a central range hood control unit or a specific ventilation control unit and a specific lighting control unit.

[0030] Alternatively, however, the operating module can also include a control and regulation unit configured to evaluate detected manipulations, so that, for example, only one interface can be provided, which can be coupled to one or more functional units in order to directly adjust the corresponding functions. In this way, the operating module can also be easily configured for retrofitting or replacing existing operating modules.

[0031] The connection between the operating module and the functional unit can thus be direct or indirect, that is, exist via another unit or component. In addition, the connection can be formed mechanically by a wire or other signal transmission device or electronically by a line.

[0032] Although the areas can be operated using buttons, each area preferably includes one or more capacitive touch sensors, wherein the operating area is preferably configured as a touch area matrix. Accordingly, planar operation is simplified in particular by continuous and unlimited detection.

[0033] Furthermore, the wiping motion can be performed and detected more easily, and a higher detection accuracy can be achieved based on the capacitance change, making it easier to distinguish between desired planar and dynamic manipulations. This significantly simplifies operation and reduces the detection of incorrect and / or unintentional manipulations. Furthermore, while simplifying the cleaning of the operating area, this design provides intuitive operation.

[0034] To change the operating mode, the operating module can be configured to change the operating mode by switching on and off and / or by changing the position of the operating panel between a first and a second position.

[0035] The operating module can thus be switched off, for example, if the range hood is to be switched off or if the adjustment is to be restricted only to the corresponding specific functions. The position of the operating panel can remain unchanged in this case.

[0036] Changing the operating mode by changing the position of the operating panel has the advantage that the operating panel can be positioned out of sight in the second operating mode. While the operating module and, if necessary, the range hood can be switched off, any previously set functions are retained, allowing the range hood to continue operating. However, in the second operating mode, targeted operation is not possible, so the functions to be adjusted are at least partially restricted, and, for example, fine-tuning of the light intensity or the fan intensity is not possible. However, basic functions can still be selected or activated by actuating multiple areas using predefined functions.

[0037] Preferably, the operating area can be arranged on the housing of the operating module or on the housing of the range hood in a rotatable or movable manner for changing its position, wherein the operating area preferably protrudes from the housing of the operating module and / or the range hood in a first position and is essentially aligned with at least one external surface of the housing in a second position.

[0038] The operating panel can thus be pulled out of the operating module or from the range hood to adjust specific functions of the range hood in the first operating mode. During operation, after inputting or selecting a corresponding function or to switch off the range hood, the operating panel can be easily moved into a second position to operate the operating module in the second operating mode. Advantageously, there is no provision for adjusting specific functions by actuating a single area, so that changes in the position of the operating panel or unintentional contact with an area do not result in an adjustment of the function.

[0039] Furthermore, the aligned arrangement has the advantage that the user does not perceive any visual obstruction when carrying out work underneath the range hood and is not adversely affected thereby.

[0040] Switching off the operating module can cause a change in the operating mode when the operating panel is in a fixed position, which is not necessary when the operating panel is arranged movably. To facilitate detection of position changes and switching to the corresponding operating mode, the range hood can include a switching element that is configured to change the operating mode of the operating module when the position of the operating panel is changed, wherein the switching element is designed as an electromechanical, capacitive, inductive, or optical switching element.

[0041] The switching element can, for example, comprise a pressure element which is arranged on the operating module or the range hood in such a way that a pressure is detected when the operating panel is in the second position, for example due to the operating panel being folded or folded into a receptacle of the range hood. A switching circuit can also be provided which is connected to the operating panel and which, when closed, activates a relay circuit in a predetermined position.

[0042] Alternatively, the range hood can include a sensor for determining the position of the operating panel and / or operating module. This sensor is arranged in the operating module and is configured to change the operating mode of the operating module when the operating panel and / or operating module is changed. Preferably, the sensor is designed as a motion sensor or a gyroscopic sensor. For example, the sensor can be directly connected to a control unit of the range hood or the operating module, so that changing the operating state does not require additional wiring or cabling.

[0043] The sensor or position sensor can be designed, for example, as a three-axis sensor, so that the position of the operating module relative to the center of the Earth can be determined. This allows precise position changes to be detected without requiring complex calibration, and furthermore allows the (absolute) orientation of the operating module or operating panel to be determined, so that a distinction can be made between the positions accordingly.

[0044] However, as an alternative, metal elements can be provided that move relative to one another when the position of the operating panel is changed and thereby detect a corresponding change in capacitance that is indicative of a change in position. Such a design can be integrated, for example, into a hinge, into a support for the operating panel or operating module, or into surfaces that face each other in the second operating mode. However, proximity switches or proximity sensors can also be provided.

[0045] The inductive circuit can also be provided, for example, by a coil integrated into the switching circuit of the range hood or the operating module, wherein the magnetic element is arranged on the operating panel or integrated therein. The optical circuit can be provided, for example, by providing an infrared sensor, an ultrasonic sensor, or a light barrier, wherein these elements are arranged so as to detect a relative movement of the operating panel relative to the range hood or the operating module when the position of the operating panel is changed.

[0046] As previously mentioned, the operating panel or area can also include one or more capacitive touch sensors, which are used to adjust specific functions in the first operating mode and at least one predetermined function in the second operating mode. In an alternative embodiment, these capacitive touch sensors can also be configured to determine the position of the operating panel and, therefore, the operating mode. Accordingly, the operating panel can be arranged on the operating module and / or the range hood such that its position relative to the housing, preferably relative to a grounding element of the housing, causes a change in the total capacitance of at least one component of the operating panel, wherein the operating module is configured to adjust the operating mode based on the detected total capacitance.

[0047] That is, by changing the relative position of the operating zones, the basic capacitance of the corresponding zones can also change. This basic capacitance and the change in basic capacitance can be different for each zone due to the different arrangements of the zones. While changes in the capacitance of individual zones are generally possible, it is preferred to detect changes in the overall capacitance. To minimize the potential influence of electrical components present in the range hood on the basic capacitance of the operating zones, a ground connection can be provided on the housing, for example, by attaching a metal foil to the base of the range hood. This advantageously improves the accuracy of detecting changes in basic capacitance and, therefore, changes in position, and eliminates the need for additional components, switches, or complex sensor systems.

[0048] As mentioned above, the operating panel can be movably arranged on the operating module or the range hood. Preferably, the operating panel can also protrude from the outer surface of the range hood in the first operating mode and can be substantially aligned with or substantially received by at least one outer surface of the range hood in the second operating mode.

[0049] As a result, the operating panel can be arranged completely out of the user's sight in the second operating mode. For example, the range hood can have a recess or receptacle in the lower region, which is designed so that the operating panel is received therein in the second operating mode and does not protrude either on the underside or on the front of the range hood. Furthermore, the recess can be dimensioned so that the complete operating module is also contained therein.

[0050] Furthermore, the range hood can include a baffle, so that the operating panel can be arranged behind it in the second operating mode. This also provides or results in a flat, continuous surface or front of the baffle, thereby simplifying the design of the range hood. In addition to easier production, the continuous baffle also offers the advantage of easier cleaning. While the basic functionality in the second operating mode is maintained through non-specific manipulation of multiple areas, fine-tuning of the corresponding functions can still be performed by simply changing the position of the operating panel or tilting it outward.

[0051] Furthermore, the baffle can be made of a material that can function as a dielectric. In particular, a transparent dielectric is used. Thus, the baffle can be made of glass or plastic, for example. By using such a material, the position detection sensor, if provided, can be configured as a proximity sensor, for which the baffle acts as a dielectric.

[0052] Furthermore, the range hood may include one or more functional units for implementing the range hood functions, wherein the operating panel is communicatively coupled to the functional units for adjusting the functions. Such communicatively coupling may be provided, for example, via an interface and / or a control and regulating unit. "Ranger hood functions" particularly include the intake of air, smoke, and steam from the area below the range hood and, in particular, the illumination of the area below the range hood.

[0053] The components required for this purpose can be designed as functional units of the range hood, which indirectly or directly influence the function of the range hood. These functional units, such as a ventilation fan unit, lighting, sensors, time measurement and monitoring units, or a range hood control system, can be designed accordingly and arranged in the range hood. These functional units typically include a plurality of functional elements, such as a fan motor, a ventilation fan, a lighting element, a lighting control system, sensor elements, time detection elements, a time switch, and signal processing elements for signal processing for the range hood control system.

[0063] exist Figure 1 1 shows a part of a range hood 1 according to one embodiment of the present invention. The range hood 1 comprises a sight hood (Sichtschirm) (not shown in detail), also called a steam hood or hood, and a chimney (not shown in detail) extending upwards from the step hood. Figure 1 1 shows a cutout of the classification hood in the area below the chimney. The classification hood has a flat box shape. The front of the classification hood can be formed by baffles as described below.

[0064] An operating module 2 having an operating area 3 is arranged on the lower side and the front area of ​​the range hood 1. The operating area 3 has a plurality of areas A1-A7. However, the number of areas A1-A7 is not limited to the number shown and can also include fewer or more areas A1-A7, such as only two or three areas A1-A7. Similarly, the arrangement shown is not limited to a row-shaped arrangement and it is not mandatory that the areas A1-A7 are adjacent to each other. The areas A1-A7 can be constructed as simple buttons, but are constructed here as capacitive touch sensors. Accordingly, the manipulation performed can be detected as a change in capacitance, and the movement on the surface of the corresponding areas A1-A7 can be carried out unlimitedly or unobstructedly and preferably steplessly according to the design of the corresponding touch sensor.

[0065] A specific function of the range hood 1 is stored for each button or each area A1-A7, so that the user can adjust this specific function by operating the corresponding area A1-A7. It can also be provided that specific areas are provided for switching the operating module 2 and / or the range hood 1 on and off. However, as an alternative, this can also be set by a specific combination of operations and / or operation methods.

[0066] In order to adjust the corresponding function, it is possible to set, for example, Figure 2 and 3 The communication coupling is shown in the exemplary embodiment of FIG. Figure 2As shown in FIG, a switch element 4 is arranged in the range hood 1. The switch element 4 forms an interface for the operating module 2 and is also communicatively connected to a central control and regulating unit 5 of the range hood 1. The operating module 2 and the operating panel 3 can thus communicate with the control and regulating unit 5 via the switch element 4. For this purpose, for example, a communication circuit (not shown) can be provided between the operating module 2 and the switch element 4, which extends via a fastening point of the operating module 2 and is connected to the operating module 2. However, a separate circuit can also be provided to enable the operating module 2 to communicate at least partially directly with the control and regulating unit 5.

[0067] Furthermore, the control and regulation unit 5 is connected to at least one functional unit 6, so that an actuation of the operating panel 3 of the operating module causes a function of the range hood 1 to be adjusted via the switch element 4 or the interface and the control and regulation unit 5. Thus, the lighting power and / or ventilation power can be controlled and regulated via the operating module 2.

[0068] according to Figure 2 The operating module 2 is furthermore pivotally mounted on the range hood 1 by means of a hinge and is in an outwardly tilted position. In this embodiment, the operating panel 3 is furthermore connected to the operating module 2, so that there is no relative movement between the operating panel 3 and the operating module 2 when the pivot position changes. However, the operating panel 3 can also be arranged so that it can be positioned independently when the operating module 2 is connected to the range hood 1, for example, and the operating panel 3 is movably mounted on the operating module 2.

[0069] In this outwardly tilted state, the operating module 2 is in a first operating mode, allowing the user to manipulate specific individual areas of the operating panel 3 to adjust corresponding specific functions of the range hood 1. In other words, the functions of the operating panel 3, and thus the operating module 2 and the range hood 1, are not restricted in the first operating mode, and specific functions and / or fine-tuning of corresponding functions can be selected arbitrarily.

[0070] In such Figure 3In the folded-up state shown, the operating module 2 is in a second operating mode, in which the functions are limited or the functions to be adjusted are at least partially deactivated. The control and regulation unit 5 and / or the operating module 2 determine the corresponding position change of the operating panel 3 using the changed capacitance value, thereby operating the operating module 2 in the second operating mode. This position change can be determined by the switching element 4 or by a corresponding element integrated in the hinge 7 and coupled to the switching element 4, such as an integrated Hall element or two elements arranged for relative capacitance measurement.

[0071] In this state, the control panel 3 is out of the user's field of vision, and indirect operation of the control panel 3 can only be performed behind a cover 8 provided for concealment. Accordingly, in this state or in the second operating mode, individual areas cannot be selected specifically. However, to ensure the functionality of the control module 2 and the range hood 1, provision is made for enabling predetermined functions, such as switching the lighting function on and off, to be adjusted by non-specific actuation of multiple areas, or two or more areas. This allows the user to continue to adjust basic functions without having to tilt the control panel 3 outward and / or switch on the control module 2.

[0072] An example of such an operation for adjusting the function is shown in the drawing and explained below.

[0073] In accordance with Figure 4 The embodiment of FIG shows the operating panel 3 in a first operating mode, in which the corresponding areas A1-A7 can be operated and selected to adjust or select corresponding specific functions, as indicated by the continuous white surface. Here, a single area A4 is operated, as indicated by the hatching. Accordingly, the user can adjust the specific function of the range hood stored for area A4 by touching area A4. Repeated operation of this area A4 can either fine-tune this function or deactivate the corresponding function. Similarly, any individual area A1-A7 can be operated to adjust an alternative function or to adapt the selected function.

[0074] In accordance with Figure 5A In the embodiment of the invention, the operating area 3 or the operating module is in the second operating mode, so that the respective specific functions are at least partially or completely deactivated, as indicated by the thin hatching of the areas A1-A3 and A5 to A7. Figure 1As indicated by the different hatching compared to the actuated area A4, actuation of a single area A4 does not result in an adjustment of the specific function stored for area A4. Such actuation can therefore be ignored by the operating module or buffered for subsequent actuation, so that, for example, unintentional contact does not result in an adjustment and manual positioning of the operating panel 3 does not trigger or adjust any function.

[0075] In the second operating mode, however, the actuation of multiple areas, ie, the planar actuation, results in the adjustment of a predetermined function, such as, for example, the switching on of light with a predetermined intensity. Figure 5B In this case, areas A4 and A5 must be touched for this purpose. However, any area A1-A7 can be selected or actuated to adjust a predefined function, and it can also be provided that the adjustment is performed when two or more areas A1-A7 are actuated. Only one flat actuation is required. Optionally, however, it can be provided that the intensity, for example, the light intensity, depends on the number of actuated areas A1-A7, depending on the preset and / or user preference.

[0076] It can also replace Figure 4 5 and perform the same dynamic manipulation as shown in Figures 6 to 8. Figures 6A to 6C In the embodiment of the invention, the two areas A2, A3 can be manipulated first and a movement to the right and a manipulation sequence can be performed as indicated by the corresponding hatched arrows. Figure 6B Alternatively, as shown in FIG6C , areas A3, A4, and finally only area A5 are actuated. Accordingly, the rightward wiping movement is determined by the operating module or the control and regulation unit. It is not important that only area A5 is actuated at the end of the movement, since multiple areas are actuated and the order of the actuated areas determines the direction of movement. Rather, the wiping movement can extend all the way to the end area of ​​the operating area 3. However, this is not necessary for determining the direction of movement and for adjusting the predefined function.

[0077] An alternative wiping motion in Figure 7A and 7B Here, areas A6 and A7 are first touched or actuated and then only area A7 is touched or actuated. In this case, a wiping movement can also be detected even at the end area of ​​the operating area 3, because an actuation sequence to the right can be detected as indicated by the corresponding hatched arrows.

[0078] However, in order to better distinguish between wiping movements and static actuations, the actuation duration can be detected, thereby distinguishing wiping movements from clicking movements, in which actuations by two fingers are not completely simultaneous. Similarly, multiple contact sensors can be provided in each area A1-A7, thereby enabling more precise actuation sequences to be detected by capacitive detection and better differentiation between static, planar actuations and brief wiping movements.

[0079] Another alternative wiping motion is Figure 8A and 8B . In this embodiment, the operating area 3 includes further areas B1-B7, which are also arranged in rows and adjacent to each other. Furthermore, the areas B1-B7 adjoin the areas A1-A7, thus providing a continuous two-row matrix of contact areas. However, such a matrix is ​​not limited to the number shown in both directions and can therefore include any number of rows and columns.

[0080] Furthermore, this embodiment allows for a wiping motion within a row. Thus, areas A4, A5, A6 are first actuated, followed by areas B4, B5, B6, so that a contact direction perpendicular to the row can be detected, as indicated by the corresponding hatched arrows. This also allows for the adjustment of predetermined functions, such as the ventilation system output at a predetermined intensity or level. Although three areas A4, A5, A6 are actuated during the wiping motion, adjustments can also be made by actuating two areas.

[0081] By means of a flat actuation, at least one predefined function in the second operating mode can be adjusted, thereby enabling easy operation and provision of the basic functions of the range hood even when the operating module and, in particular, the operating panel, are out of sight or only indirectly accessible. Furthermore, it is not necessary to switch on the operating module or select a specific function in order to adjust the predefined function, so that the user can easily activate or adjust the lighting function even in low light conditions, for example when the range hood is switched off.

[0082] Different actuation modes, in which either static or dynamic actuation is performed and / or in which the number of actuated zones can vary, can also adjust different predefined functions of the range hood. Thus, the number of actuated zones, for example two or three, or the direction of the wiping movement can also correspond to the respective different predefined functions.

[0083] However, it can also be provided that these different operating modes represent at least some redundancy in order to further simplify operation. Thus, for example, the same predefined function can be set both in static operation of two areas and in static operation of three areas, and the same predefined function can be set in a wiping movement within a row as in a wiping movement within a column. In the latter case, however, an opposite direction can be detected, for example, to switch off a predefined function.

[0084] As a result, different manipulations can be distinguished from one another and different predefined functions can also be provided to the user in the second operating mode, while at the same time unintentional or even erroneous manipulations can be effectively avoided or ignored.
