Description

The invention relates to an operating device for a cooker hood and an extractor hood with such a control device.

For actuating functions of an extractor hood actuators, such as buttons or slides are known. These are in hoods, which are installed in a wall unit of a kitchenette, usually attached to the bottom of the fan module, which is the main part of such cooker hoods attached. Such cooker hoods are also referred to as Flachschirmhauben, under hoods and Zwischenbauhauben. A disadvantage of this arrangement is that the user does not have a clear view of the actuators and thus must feel them. In addition, actuators, which are mounted so exposed to high pollution by fumes and vapors.

The invention is therefore an object of the invention to provide a solution in which these disadvantages of the prior art in a simple manner and with a simple structure of the keypad device and the hood can be eliminated or at least reduced.

The invention is based on the finding that this object can be achieved by a holder of the actuating element is movably attached to the hood.

According to a first aspect, the object is achieved by a control device for an extractor hood. The extractor hood is characterized in that the operating device has at least one outer housing fixed to the housing with an open side for receiving at least a part of an inner housing and at least one inner housing for receiving at least a part of an operating part, that the inner housing is attached to the outer housing at least partially movable at least one operating part with at least one actuating element for at least one function of the extractor hood at least on the inner housing is held in some areas and that the inner housing can be brought to the outer housing in at least one state of rest and at least one operating state.

Directional information, such as front, back, top or bottom, unless otherwise stated, refers to a keypad device mounted in the bottom of a cooker hood with the open side of the outer casing facing down

For the purposes of the present invention, a control device is understood to mean a device which has, on the one hand, at least one actuating element for at least one function of the extractor hood and, on the other hand, a holder for holding the at least one actuating element on the extractor hood.

For the purposes of the present invention, an extractor hood is preferably understood to be an extractor hood which comprises a fan component. Such extractor hoods are in particular under hoods, intermediate hoods or Flachschirmhauben. The fan component is the part of the extractor hood, in which the suction opening is provided for sucking in fumes and vapor. In addition, a suction space for supplying air to the fan of the extractor hood is preferably provided in the fan module. It is also within the scope of the invention that the fan is received in the fan module. The fan module is integrated with cooker hoods, especially in under hoods, intermediate hoods or flat screen hoods in a kitchenette, especially in one of the upper cabinets of the kitchen unit or mounted between two upper cabinets and dressed forward. In particular, in intermediate hoods and under hoods while the front of the fan module is not visible to the user.

According to the invention, the operating device device has at least one outer housing and at least one inner housing. The outer housing is in this case a housing-fixed component, that is fixedly mounted on the hood and in particular the fan module. Permanently mounted in this context means that the outer housing can not be moved in the installed state with respect to the hood. However, it is within the scope of the invention and it is preferred that the outer housing is releasably connected to the extractor hood, that is, from this can be removed. The outer housing is preferably accommodated in the extractor hood so that only one side lies in an outer side of the extractor hood or adjoins it. The other sides of the outer housing are preferably completely accommodated in the extractor hood.

According to the invention, the outer housing has an open side for receiving at least part of the inner housing. The other sides of the outer housing can be closed walls. Preferably, however, at least passage openings for fastening the inner housing are provided in the further walls. In addition, the side facing away from the open side of the outer housing may also be open, so that the outer housing forms only a frame. The open side of the outer housing is preferably the underside of the outer housing in the mounted state of the operating device. The inner housing can be moved out of this via the open side of the outer housing and introduced into this. The open side therefore has an opening corresponding to the size of the inner housing. On the open side, in one embodiment, only the lower edge of the side walls of the outer housing may be present. It is also within the scope of the invention to provide a collar or flange on the open side. This is particularly advantageous for mounting the control panel device to the hood.

The inner housing is attached to the outer housing and at least temporarily received in the outer housing. In particular, the inner housing is preferably received in the outer housing such that one of the sides of the inner housing lies in or adjoins the open side of the outer housing. The open side of the outer housing is preferably the side of the outer housing which lies in the outer side, in particular the underside of the extractor hood. The inner housing is movably attached to the outer housing. As a movable attachment is understood in this context, a fastening that allows relative movement of the inner housing to the outer housing, without the connection to the outer housing is released or repealed. In this case, at least a part of the inner housing is moved relative to the outer housing. It is also within the scope of the invention that the entire inner housing is moved relative to the outer housing. In the latter case, however, the connection between the inner housing and the outer housing remains at least over at least one guide element, which may for example represent a damping element or an acceleration element exist.

At least one operating part with at least one actuating element for at least one function of the extractor hood is held at least partially on the inner housing. Particularly preferably, the control unit is accommodated in the inner housing. In this case, at least part of a side of the operating part lies in one side of the inner housing, preferably in the front side of the inner housing. The side of the inner housing, in which at least part of the one side of the operating part is located, is preferably offset, in particular perpendicular, to the side of the inner housing which lies in the open side of the outer housing. On the side of the operating part, which lies at least partially in one side of the inner housing, the actuating element or the actuating elements of the operating part is preferably provided. An actuating element is an element by means of which the user can influence at least one function of the extractor hood and in particular activate, deactivate or adapt it. For example, the actuating element is a button, a push button or a slider. In the control panel, the electrical, electronic and / or mechanical devices are preferably also included, being influenced by the function of the extractor hood, which is caused by the actuation of the actuating element. To influence the function, the inner housing is not moved according to the invention. At most, a part of the control panel, in particular an actuator is moved in the control panel.

According to the invention, the inner housing can be brought to the outer housing in at least one idle state and at least one operating state. The operating state here is a state in which at least one of the operating elements of the operating part is accessible to the user of the extractor hood. As a state of rest, the state is referred to, in which at least part of the actuating element is at least partially accommodated in the hood and thus is not accessible to the user.

By in the present invention, the outer housing is fixedly connected to the hood and a movably held therein inner housing for receiving and fixed support of the control panel is provided, the relative position of the Inner housing and thus the control panel to be changed to the hood. This makes it possible to bring the control panel at least partially at least partially in the field of view and thus the user's intervention area. Such a change in position is possible only with the embodiment of the keypad device according to the invention. In contrast to the present invention, for example, in a slider provided on the hood, only the actuator, that is, the slider is movable relative to the hood. The guide in which the slider is held and which can be compared with a housing according to the present invention, however, is firmly connected to the hood.

In addition, the inventive structure of the control panel device has the advantage that the overall structure of the hood is simplified. In particular, only one fixed connection is necessary between the extractor hood and the outer housing, and between the operating part and the inner housing. Such connections can be realized in a simple manner, for example by providing an opening on the hood, in which the outer housing can be accommodated and held by fastening means such as locking lugs. A structural change of the hood is therefore not required. Also, control panels must be attached in all applications to a part of the hood and have for this purpose usually fastening means, for example in the form of locking lugs on. For fixed connection of the control panel in the inner housing so that at least one detent opening is provided only in the inner housing into which this latch can engage. A structural change of the control panel is therefore also not required. This further simplifies the production of the extractor hood.

In addition, the maintenance is simplified, since the movable connection is provided only between the inner housing and the outer housing, which form part of the control panel device. The keypad device can preferably be detached from the extractor hood, that is, be removed from it, so that the moving parts can be easily cleaned or replaced.

According to a preferred embodiment, the control unit is completely accommodated in the rest position in the outer housing and / or the control panel protrudes in the operating state at least partially out of the outer housing.

In the assembled state of the control panel device in an extractor hood, the control panel in the idle state is preferably in the hood so that it does not protrude beyond one of the outer sides, for example, the underside of the hood. Particularly preferably, the control panel is completely in the hood in the hibernation. Preferably, the outer housing is located in the hood so that its open side lies in one of the outer sides, preferably in the underside of the hood. In this embodiment, the control unit is in the rest state in the outer housing so that it does not protrude beyond the open side thereof. If, however, the outer housing is arranged to the outside of the extractor hood inwardly in the extractor hood, the operating element can protrude in the idle state over the open side of the outer housing, as long as it does not protrude beyond the outside of the extractor hood.

For the relative position of the inner housing to the outer housing of the keypad device, this means that the inner housing in the idle state preferably does not protrude beyond the open side of the outer housing or only by an amount corresponding to the offset of the open side of the outer housing to the outside of the hood , stands out. Preferably, the inner housing is completely received in the rest state in the outer housing. In this embodiment, the height of the outer housing is at least equal to the height of the inner housing.

In the operating state, the control panel preferably projects beyond at least one outside of the extractor hood, in particular the underside of the extractor hood, at least in some areas. Particularly preferably, in the operating state, at least the actuating element or elements protrude beyond the outside of the extractor hood.

Since the outer housing is preferably provided on the hood so that its open side in one of the outer sides of the hood, in particular the

Bottom of the hood, or offset to this outside inwardly arranged in the hood, the control panel protrudes in the operating state at least partially beyond the open side of the outer housing. Since the control unit is held firmly in the inner housing, thus also protrudes the inner housing in the operating state at least partially beyond the open side of the outer housing.

Since the inner housing to the outer housing is at least partially movable, the inner housing can be brought from the idle state to the operating state and vice versa. In the idle state and the operating state, the control panel is held over the inner housing.

Preferably, in the operating state, the operating part will protrude so far beyond the outer housing and beyond the outside of the extractor hood that the actuating element or elements on the operating part project beyond the outside of the extractor hood. This allows the user to operate the actuator or the operating state. In the idle state, the actuating element or elements are preferably accommodated in the extractor hood and in particular in the outer housing. As a result, the actuators can be protected from contamination in the vapors and vapors.

According to one embodiment, the inner housing is rotatably connected to the outer housing. As a rotatable connection in this case a connection is referred to, in which the inner housing relative to the outer housing can perform a rotational movement. Here, the rotation of the inner housing to the outer housing is preferably limited to a predetermined angular range. In addition, the rotation or rotation preferably takes place about an axis which is parallel to the open side of the outer housing. The rotation or rotation of the inner housing to the outer housing can therefore also be referred to as pivoting or tilting.

An advantage of the rotatable connection between the outer housing and the inner housing of the keypad device is that the connection between these two components can take place via a fixed axis. Thus, on the one hand the structure of the control device is simplified and on the other hand, a secure hold of the control panel in the operating position in which this against the Outside housing is pivoted to be guaranteed. Furthermore, with a rotatable connection between the inner housing and the outer housing, it is possible to unscrew the operating element so far beyond the open side of the outer housing that the actuating elements protrude beyond the outer housing, without the side surface of the operating part, which is opposite the actuating element or the actuating elements, also passing over the outer housing must stand out. Thus, the surface of the control panel, which is in the mounted state of the control panel device in the operating state on the outside of the hood, in particular the underside of the hood is also minimized. This also minimizes the risk of contamination.

According to a preferred embodiment, the axis of rotation about which the inner housing can be rotated relative to the outer housing is parallel to the open side of the outer housing. In addition, the axis of rotation is preferably in the rear region, preferably at the rear of the outer housing and inner housing in the lower region, that is, in the vicinity of the open side of the outer housing provided. As a result, the front side of the inner housing can be pivoted out of the outer housing without the rear side of the inner housing having to be pivoted upwards in the outer housing. An advantage of this is that the space required for the keypad device is reduced, and yet the largest possible part of the front of the inner housing and thus the keypad can be swung out of the outer housing. This also larger actuators can be used on the control panel.

The axis of rotation is preferably formed by an integrally formed on the inner housing part axis and an integrally formed on the outer housing part axis. In addition, elastic elements are provided on the inner housing or the outer housing, via which the sub-axes are held aligned with each other. These elastic elements may be tabs, for example. The advantage of this embodiment is on the one hand in the reduction of the number of parts required for the keypad device. In particular, a separate metal pin, which is otherwise used as an axle, omitted. In addition, the assembly of the keypad device is simplified.

According to a further embodiment, the inner housing is slidably connected to the outer housing. In this embodiment, the inner housing is preferably at least partially displaceable beyond the open side of the outer housing. The direction in which the inner housing is displaceable relative to the outer housing is preferably perpendicular to the open side of the outer housing. By the inner housing relative to the outer housing is slidably connected to the outer housing, a translational movement can be performed by the inner housing. The advantage of this embodiment is in particular in the simple embodiment of the compound by means of which such a translatory movement is possible. In addition, in this embodiment, the connection between the inner housing and the outer housing can be solved if necessary, for example, for maintenance purposes in a simple manner. This simplifies the manufacture and maintenance of the keypad device.

The control panel is preferably held firmly in the inner housing. As held firm in this case, a connection between the inner housing and the control panel is designated, which prevents relative to the inner housing and the control unit in the assembled state of the control panel device relative movement. For maintenance purposes or for cleaning, however, the operating part can preferably be removed from the inner housing. The connection between the inner housing and the control unit is therefore preferably detachable. As held in the inner housing is understood in the context of the invention, an arrangement and mounting of the control panel, in which at least one, preferably at least four sides of the control panel are surrounded by walls of the inner housing. The front side of the operating part is hereinafter referred to as the side on which the at least one actuating element is provided. Side surfaces are understood to be the surfaces of the operating part which adjoin the front side and which are inclined to the front side and are preferably arranged perpendicular thereto. Preferably, the control panel is at least two, more preferably at four of the side surfaces, at least partially surrounded by walls of the inner housing. By the control panel is held firmly in the inner housing, but preferably releasably connected thereto, a maintenance and optionally an exchange of the control panel can be done in a simple manner. At the same time, however, uncontrolled shifting of the operating part in the inner housing can be prevented by the fixed support of the operating part in the inner housing.

According to one embodiment, at least one acceleration element is provided in the connection between the inner housing and the outer housing. As provided in the connection in this case is understood an element that can influence the connection between the inner housing and the outer housing. However, the actual mounting of the two housings to one another does not necessarily have to take place via the acceleration element. An acceleration element is understood to be a component that supports an initiated relative movement of the two housings relative to one another in one of the directions of movement. The accelerator element preferably constitutes a spring element, for example a leg spring or a roll spring. By supporting the movement of the housings relative to one another by the accelerator element, the handling of the operating device for the user is facilitated. In one embodiment, the acceleration element is provided so that it supports the movement of the inner housing out of the outer housing, that is, the movement from a rest state to an operating state. In an alternative or additional embodiment, the accelerator element assists movement of the inner housing into the outer housing, that is, the movement from the operating state to the rest state.

Preferably, at least one damping device is provided in the connection between the inner housing and the outer housing. As provided in the connection in this case is understood an element that can influence the connection between the inner housing and the outer housing. However, the actual mounting of the two housings to one another does not necessarily have to take place via the damping device. According to one embodiment, however, the damping device at least partially contributes to the retention of the inner housing on the outer housing. As a damping device is a preferably multi-part device is referred to, which slows relative to each other relative movement of the two housing at least in one direction, that is, the movement of the housing in this one direction opposes a counter force. By at least one damping device is provided, for example, an uncontrolled falling or pivoting of the inner housing can be prevented in the outer housing.

According to one embodiment, the damping device consists of a damping element and a cooperating damping structure. The damping element may for example be a rotary damper with a gear. According to a preferred embodiment, the damping element is a component with a tooth geometry. In particular, the damping element may be a rotatably mounted gear with an attenuation about the axis of rotation of the gear. The damping element is preferably a component which is separate from the two housings. In this way, the structure of the two housings can be kept simple and yet an uncontrolled relative movement can be prevented.

Preferably, the damping structure is formed on the outer housing or the inner housing. This means that the damping structure can be introduced into the housing, for example can be recessed or can be molded onto one side of the housing. According to one embodiment, the damping element is connected to the inner housing of the operating device and cooperates with a damping structure, in particular tooth structure, on the outer housing, preferably in one of the side walls of the outer housing. However, the arrangement can also be realized the other way around by the damping element is provided on the outer housing and the damping structure, in particular tooth structure, is provided on the inner housing.

Preferably, at least one locking mechanism is provided in the connection between the inner housing and the outer housing. As provided in the connection, a mechanism is understood that can influence the connection between the inner housing and the outer housing. However, the actual mounting of the two housings to one another does not necessarily have to take place via the latching mechanism. According to one embodiment, however, the latching mechanism at least partially contributes to the retention of the inner housing on the outer housing.

Preferably, the latching mechanism comprises a latching element and a Verrastgeometrie for guiding the latching element. The latching element is in this case preferably formed on the outer housing or the inner housing. As a latching element, which is also referred to as a latching element, in this case a device denotes, which fixes the relative position of the two housings to each other at least temporarily. Particularly preferably, the relative position of the two housings is fixed to each other in the rest position and / or the operating position by the latching element. Preferably, a separate latching element and an associated Verrastgeometrie is provided for each position. The latching element preferably cooperates with at least one Verrastgeometrie, which allows a release of the Verrastverbindung and guiding into the latching position. The latching element may, for example, represent a triangular or diamond-shaped dome on one of the housings. The Verrastgeometrie preferably represents a structure, in particular a Herzkurvenkulisse. By using such Verrastmechanismus, the release of the temporary fixed relative position of the housing to each other can be done easily. In addition, the Verrastmechanismus may be provided inside the keypad device, as to actuate such a latching mechanism, a pressure application from the outside to the inner housing is sufficient.

According to a preferred embodiment, at least the damping structure is designed in one piece on one of the housings. This means that the damping structure is integrally formed on the housing or, for example, incorporated in a housing wall. In addition, the latching element is preferably designed in one piece with one of the housings, that is to say formed on one of the housings. The latching geometry is preferably a separate component to the housings or is incorporated in such a separate component. The separate component is preferably connected to one of the housing by clipping or hooking. This has the advantage that the remaining geometry of the housing is simple and can optionally be produced by methods such as deep drawing or injection molding.

According to a preferred embodiment, the operating device device comprises an outer housing and an inner housing rotatably held therein. The control panel is attached via fastening means on the side walls in the inner housing. The axis of rotation lies in the rear lower area of the inner housing and the outer housing and is parallel to the open side of the outer housing. In at least one of the side walls of the outer housing, a damping structure in the form of a part-circular tooth structure is introduced. In addition, in at least one of the side walls of the outer housing at least one passage for securing and passing through a Guide element provided with a Verrastgeometrie in the form of a Herzkurvenkulisse. On the inner housing, a passage for a damping element in the form of a gear with rotary damper is provided on at least one side wall and such a damping element is fixed in the passage. The damping element is attached to the inner housing so that it engages with the damping structure of the outer housing and can run along it. In addition, on at least one side wall, a latching element, in particular in the form of a diamond-shaped dome, which can be brought into engagement with the Verrastgeometrie the guide part, which is clipped on the outer housing in engagement. Finally, an acceleration element in the form of a leg spring is provided, one leg of which rests on the inside of the rear wall of the outer housing and the other leg either on the outside of the rear wall of the inner housing or in a rearwardly open inner housing at the top of the lower wall. The two housings are rotatably connected to each other via a split axle, wherein at least one part-axis is integrally formed on the inner housing and a part-axis on the outer housing. The leg spring is attached to the axle. In the front of the outer housing, a spring structure is formed, which comes into contact with the front upper edge of the inner housing during pivoting of the inner housing and is pushed forward by the latter. The spring structure has an inwardly directed projection, which counteracts the unwanted pivoting of the inner housing.

In this embodiment, the inner housing can be swung out with the operating part of the outer housing by being pressed from below against the underside of the inner housing. By this pressure, the latching element is guided in the Verrastgeometrie that it can escape down from this. The movement down, that is in the operating state is supported by the leg spring. The damping element, which runs along the damping structure, slows down this movement. Shortly before reaching the operating state, the front upper edge of the inner housing comes into contact with the spring structure on the outer housing and pushes it forward. After passing the projection on the spring structure, the leading edge rests on a retaining edge formed under the spring structure in the front of the outer housing. The spring structure with the retaining edge can thus in the context of the invention as a further Verrastgeometrie and the front upper edge of the inner housing, which is preferably rounded, referred to as another latching element become. To return to the idle state, the inner housing is pressed from bottom to top. In this case, the spring force of the spring structure of the outer housing is overcome. Subsequently, the dome engages with the heart cam slot and is guided into a latching position and the inner housing is thus held in the rest position.

According to a further preferred embodiment, the operating device device comprises an outer housing and an inner housing which is displaceably held therein in the vertical direction. The control panel is attached via fastening means on the side walls in the inner housing. In at least one of the side walls of the outer case, a passage for a damper member in the form of a rotary damper gear is provided, and such a damper member is fixed in the passage. In the back of the outer housing, a passage for securing and passing through a guide element is provided with a Verrastgeometrie in the form of a Herzkurvenkulisse. At the front of the outer housing, a passage for holding one end of a scroll spring is provided at the lower portion. On at least one side wall of the inner housing, a damping structure in the form of a vertical tooth structure is introduced. The damping element is attached to the outer housing so that it engages with the damping structure of the inner housing and can run along it. In addition, a latching element, in particular in the form of a triangular dome, which can be brought into engagement with the latching geometry of the guide part, which is clipped onto the outer housing, is integrally formed on the rear side of the inner housing. Finally, an acceleration element in the form of a scroll spring is provided, whose free end is fixed in the passage in the lower region of the front of the outer housing. The rolled-up part of the scroll spring is rotatably mounted in a receptacle in the top of the inner housing. The roll axis of the scroll spring is horizontal.

In this embodiment, the inner housing can be moved with the control panel out of the outer housing down by being pressed from below against the underside of the inner housing. By this pressure, the latching element is guided in the Verrastgeometrie that it can escape down from this. The movement down, that is in the operating state is supported by the scroll spring. The damping element, which runs along the damping structure, slows down this movement. Upon reaching the operating state, the damping element meets the provided at the upper end of the steam structure retaining edge. One further displacement of the inner housing relative to the outer housing is therefore not possible or to be feared. To return to the idle state, the inner housing is pressed from bottom to top. Here, the spring force of the scroll spring is counteracted. Subsequently, the dome engages with the heart cam slot and is guided into a latching position and the inner housing is thus held in the rest position.

According to a further aspect, the invention relates to an extractor hood with at least one operating device. The extractor hood is characterized in that the operating device is designed according to the invention.

Advantages and features that are described with respect to the control panel device apply - as applicable - according to the cooker hood and vice versa.

The operating device is preferably arranged in the extractor hood such that the open side of the outer casing lies in one of the outer sides of the extractor hood. Particularly preferably, the open side is in the bottom of the hood or is at least so introduced into the bottom of the hood that the control panel of the keypad device in the operating state on the underside of the hood protrudes so far that the user from the front of the or the actuators on the Control panel can access.

An advantage of a cooker hood with the control panel device according to the invention is that both the operating aspects can be taken into account as well as contamination of the actuators can be largely prevented. In addition, the construction of such an extractor hood is simple, since the extractor hood itself no separate brackets and guides for the control panel must be installed. The entire mechanism for connecting the control panel with the hood and the movement of the control panel with respect to the hood are integrated in the control panel device according to the invention. This is preferably detachably connected to the extractor hood and is a preassembled unit, which only has to be introduced into the extractor hood.

According to the invention, it is also possible to arrange the control panel device on the extractor hood that the open side of the outer housing over which the

Inner housing with control panel can be moved out, located in a top of the hood or one of the side walls of the hood. In these embodiments, it may be in the hood for example, a so-called Esse or other freely mounted on the wall or in the room extractor hood, which have a viewing hood with chimney connected above.

Preferably, however, the extractor hood is an extractor hood with fan module. The extractor hood preferably has only the fan module and a suitable air duct for exhaust air. Such an extractor hood can then be installed in a wall unit of a kitchen or clad with a kitchen front. In the case of these extractor hoods, which are also referred to as under-hood or intermediate hood, in the mounted state of the hood of this is seen from the front of anything. Thus, the use of an operating device according to the invention in particular with such hoods has the advantage that the actuating element can be protected against contamination by inserting or pivoting into the outer housing on the one hand. On the other hand, however, the actuators can be visible to the user in the operating state and can be operated by him in a simple and reliable manner.

According to a preferred embodiment, the operating part therefore protrudes in an operating position at least partially over the underside of the extractor hood, preferably over the underside of the fan module.

In FIG. 1 is a side view of a fan module 10 of a first embodiment of the extractor hood 1 according to the invention shown schematically. The fan module 1 can also be called Wrasenschirm or viewing hood of the hood 1 and in particular represents the lower part of an extractor hood 1. Above the fan module 10 is usually followed by an exhaust duct. The fan module 10 in the FIG. 1 is shown without paneling. Such a fan module 10 can be integrated into a wall unit of a kitchenette or provided with a panel and then serve as a lower part of a forge. In the fan module 10, the suction opening of the extractor hood 1 is preferably introduced, are sucked through the fumes and vapor into the interior of the hood 1.

In the underside of the extractor hood 1, in particular of the fan module 10, an operating device 2 is introduced. The operating device 2 is in the embodiment according to FIG. 1 at least partially relative to hood 1, in particular the fan module 10, pivotally, that is rotatable. In particular, a part of the operating device 2 can be swung down over the underside of the fan module 10.

For reasons of better readability, in the following explanations are made essentially with reference to the fan module 10. However, the statements apply accordingly for the hood 1 as a whole, unless otherwise stated. Thus, for example, the introduction of the control device 2 in the bottom of the fan module 10 can also be understood as being introduced into the underside of the extractor hood 1.

The state in which the operating part 22 in the inner housing 21 is swung down over the underside of the fan module 10 is referred to as the operating state or operating position and is in the FIG. 1 shown. As it turned out FIG. 2 shows, which is a schematic front view of the fan module 10 of the embodiment of the hood 1 after FIG. 1 is shown in the operating position with the operating device 2, in the operating position of the operating device 2 on the front of the Operating device 2 an actuator 23 of a held in the operating device 2 keypad 22 for the user of the hood 1 accessible.

If the keypad device 2 from the in the Figures 1 and 2 The operating device 2 and thus also the actuating element 23 in the fan module 10 vanishes. The underside of the operating device 2 is then in the so-called rest position flush with the underside of the fan module 10 or is slightly downwards relative to the underside of the fan module 10 or offset above.

The construction of a first embodiment of the inventive keypad device 2 will now be described with reference to FIGS. 3 to 7 explained in more detail. In FIG. 3 is a schematic part exploded view of a first embodiment of a keypad device 2 according to the invention shown.

The operating device 2 has an outer housing 20 and an inner housing 21. The dimensions of the inner housing 21 are smaller than those of the outer housing 20, so that the inner housing 21 can be accommodated in the outer housing 20. In the inner housing 21, a control panel 22 is held.

In the illustrated embodiment, the outer housing 20 is a downwardly open frame. The bottom thus forms the open side 200 of the outer housing 20. The outer housing 20 is open in the illustrated embodiment also upwards. However, it is also possible to close the outer housing 20 upwards or to integrate a cover (not shown) in the outer housing 20. At the front of the outer housing 20 fastening means 201 are provided for securing the outer housing 20 in a corresponding recess in the underside of the fan module 10. In one of the side walls 200 of the outer housing 20, openings and passages are provided over which, as will be explained in more detail later, elements for influencing the movement of the inner housing 21 in the outer housing 20 can pass through or engage.

In the side wall 202 of the outer housing 20, a damping structure 241 of a damping device 24 in the form of a part-circular tooth structure is introduced. In addition is in the side wall 202 of the outer housing 20, a passage for attaching and engaging a guide member 261 of a latching mechanism 26 is provided. The executed as a separate component guide element 261 has in the lower part in the in FIG. 3 the outer housing 20 side facing a Verrastgeometrie 262 in the form of a Herzkurvenkulisse (see FIG. 5 ).

The inner housing 21 has a box shape open to the front. In the side walls 210 of the inner housing 21, openings and passages are also provided in the illustrated embodiment.

The insertable into the outer housing 20 inner housing 21 is rotatably supported in the outer housing 20. The axis of rotation lies in the rear lower region of the inner housing 21 and the outer housing 20 and is parallel to the open side 200 of the outer housing 20.

On the inner housing 21, a passage for a damping element 240 of the damping structure 241 is provided on the side wall 210 in the form of a gear with a rotary damper. The damping member 240 is fastened by clipping from the inside through the side wall of the inner housing 21. The damping element 240 is attached to the inner housing 21 so that it engages with the damping structure 241 of the outer housing 20 and can run along it. In addition, on the side wall 210, a latching element 260, formed in the form of a diamond-shaped dome, which can be brought into engagement with the Verrastgeometrie 262 of the guide member 261, which is clipped to the outer housing 20. The Verrastgeometrie 262, in particular the Herzkurvenkulisse together with the Verrastelement 260, in particular the Doms, assumes the Verrastungsfunktion the keypad device 2 and in particular the two housings 20, 21 against each other. In doing so, when the pressure is applied against the inner housing 21, the dome moves from the bottom in the curve of the curve of the heart, is held once and released the next time on the other side.

In the front of the outer housing 20, a spring structure 204 is formed at the edge, which comes into contact with the front upper edge of the inner housing 21 during pivoting of the inner housing 21 and is pushed forward by the latter. The spring structure 204 has an inwardly directed projection (not visible), which counteracts the unwanted pivoting of the inner housing 21 upwards.

In the inner housing 21, a control panel 22 is inserted from the front. Again, this has a box shape in the illustrated embodiment. On the side walls 220 of the operating part 22 locking lugs are provided as fastening means 221 for fastening the operating part 22 in the inner housing 21 in the illustrated embodiment. At the front of the operating part 22 actuators 23 are provided, for example in the form of buttons or the like. In the inserted state of the operating part 22 in the inner housing 21, the actuating elements 23 form the front side 211 of the inner housing 21.

Furthermore, the operating device 2 comprises an acceleration element 25, which according to the embodiment in FIG. 3 represents a leg spring.

In FIGS. 4 to 7 is the internal structure of the keypad device 2 after FIG. 3 shown in more detail. In the FIGS. 4, 5 and 7 the inner structure is shown in the rear area. The inner housing 21 is shown here in a fully, the bite by 90 ° downwardly pivoted position. In the rear lower portion of the inner housing 21 21 tabs 280 are provided on the side walls of the inner housing, which extend in the width direction of the inner housing 21. However, the length of the tabs 280 is less than the width of the inner housing 21. In the middle of the rear lower portion of the inner housing 21, a partial axis 28 is provided in the center of the underside of the inner housing 21, which also extends in the width direction of the inner housing 21.

On the inside of the rear wall of the outer housing 20, two sub-axes 27 are provided and held in the illustrated embodiment via webs on the rear wall of the outer housing 20. In the assembled state, the partial axis 28 of the inner housing 21 is in an axis with the split axis 27 of the outer housing 20. The two axes are also held by the tabs 280 which engage the split axis 27 of the outer housing 20 relative to each other. The rotational movement of the two housings 20 and 21 against each other thus takes place via this split axis 27, 28. The resiliently configured elements, which in the illustrated embodiment as Tabs 280 are formed, the inner housing 21 claw the inner housing 21 and rotate about the split axis 27 of the outer housing 20. The advantage of this concept is the absence of an extra metal pin, which is normally necessary for the rotational movement. This would result in a more complex installation and additional costs. Due to the structurally split axle 27, 28 according to the preferred embodiment, the function of the metal pin in the outer and inner housings 20, 21 is implemented. The assembly is kept very simple by the Verklippung.

Moreover, in FIG. 5 the position of the acceleration element 25, which represents a leg spring in the illustrated embodiment shown. The leg spring is placed on the axis 28 of the inner housing 21. The one leg of the acceleration element 25 abuts against the inside of the rear wall of the outer housing 20 and the other leg at the top of the lower wall of the inner housing 21 at.

The Endlagenarretierung the keypad device 2 takes place in the illustrated embodiment via a further latching mechanism, which is formed by the spring structure 204, an introduced in the front of the outer housing 20 retaining edge and the front upper edge of the inner housing 21. The spring structure 204 represents a resilient element, which is formed in the manufacture of the outer housing 20 with this one-piece in the front side of the outer housing 20. When swinging out of the inner housing 21 from the outer housing 20, the spring structure 204 of the outer housing 20 by the upper front edge of the inner housing 21, on which, for example, an outer circular element (not shown) may be formed, pushed away, that is pushed forward. When the operating part 22 or the inner housing 21 is tapped from below, this resilient element or the spring structure 204 forms a slight counterpressure, which is strong enough to prevent the operating part 22 from pivoting back into the rest position, that is to say its initial position. Only at a slightly greater pressure is the resilient member 204 and the control panel 22 can then with the inner housing 21 up to its initial position, ie the idle state, be pivoted.

In this first embodiment, the operating device 2 thus comprises an outer housing 20 and the inner housing 21 rotating therein. When "tapping", the latching element 260 leaves the Verrastgeometrie 262, which can also be referred to as a labyrinth guide of the guide piece 261. The control panel 22, which is clipped into the inner housing 21 is swung out, for example, a maximum of 32 ° attenuated. The maximum swing angle can be adjusted accordingly by design changes. For the accelerated rotational movement, the acceleration element 25, which in the illustrated embodiment may also be referred to as a pivot spring, is used, which is fastened to the inner housing 21.

In FIGS. 8 to 13 a second embodiment of the keypad device 2 according to the invention is shown. In this embodiment, it is a keypad device in which the inner housing 21 can be moved in the outer housing 20, that is, performs a translational movement. As is clear from the FIGS. 8 and 9 results, the control panel with the inner housing 21 is moved out in this embodiment in the vertical direction from the bottom of the fan module 10 down.

Also in this embodiment, the keypad device 2 consists of an outer housing 20, an inner housing 21 and a recorded in the inner housing 21 control panel 22 with actuators 23. The outer housing 20 has a downwardly open box shape. At the front and back of the outer housing 20 fastening means 201 are provided, via which the outer housing 20 can be introduced into a corresponding opening in the underside of the viewing hood 10 of the hood 1. In this embodiment, in each of the side walls 200 of the outer housing 20, a passage opening is provided, through which a damping element 24, which is realized as a gear with rotational damper, can reach through.

The inner housing 21 has a box shape open to the rear. In the front of the inner housing 21 in this case passage openings 212 are introduced for actuators 23 of the control panel 22. In the side walls of the inner housing 21 longitudinal slots are provided, wherein one of the longitudinal edges of the slots by a Tooth structure is formed in the form of a rack. This tooth structure forms the damping structure 241, along which the damping element 240 can run. At the upper end of the slot, a retaining edge 213 is formed.

The height of the inner housing 21 is higher than the height of the operating part 22, which can be introduced from behind into the inner housing 21. In the top and over part of the front of the inner housing 21, a receptacle 29 is provided, in which an acceleration element 25 can be used in the form of a scroll spring. The coil or the coil of the scroll spring is held in this receptacle 29, for example via a shaft. The free end 250 of the scroll spring has a T-shape, which can be introduced into a corresponding recess in the lower region of the outer housing 20. On the back, the inner housing has a latching element, in the form of a triangular geometry. This extends from the back of the inner housing 21 to the rear and can thus be brought into engagement with a Verrastgeometrie 262 of a guide member 261 which is provided through the back of the outer housing 20.

At the in FIG. 10 shown second embodiment of the keypad device 2, this consists of an outer housing 20, which constitutes a fixed part, and an inner housing 21, which constitutes a movable part of the operating device 2. The type of movement here is preferably linear. The maximum travel is for example 27mm. However, this can be adjusted accordingly by design changes.

The latching of the two housings 20 and 21 against each other by means of a latching mechanism 26, which includes the latching element 260 and the Verrastgeometrie 262. The latch member 260, which represents a triangular geometry, moves as in FIG FIG. 13 can be seen in the Herzkurvengeometrie the rotating guide piece 261. In this case, the inner housing 21 is held once in the heart cam center. On the next "tap" it is led out due to the tapered outer edge of the guide piece 261 on the other side of the heart curve and the inner housing 21 thereby moves downward.

The acceleration of the inner housing 21 is realized by means of the scroll spring. In this case, the T-section of the scroll spring is held in the outer housing 20 and the scroll spring tensioned by the upward movement of the inner housing 21.

The invention thus provides a rotary and / or translationally functioning operating device for deployable or retractable operating parts. Benefits include a haptic comfortable, non-motorized, in a small space as possible buildable, cheap solution that can be triggered preferably by tapping.

Significant advantages of the present invention are, among other things, that if necessary, there is a clear view of the control panel that the actuators, which can also be referred to as control buttons, especially when not in use, and the resulting increase in comfort when using a fan module. Finally, in the present invention, less pollution of the actuators than in previous actuators to be feared.
