Description

The invention relates to an extractor hood with an operating device.

Actuating elements, such as buttons or sliders, are known for actuating functions of an extractor hood. These are usually attached to extractor hoods that are installed in a wall unit in a kitchen unit, on the underside of the fan module, which is the main part of such extractor hoods. Such extractor hoods are also referred to as flat screen hoods, undercounter hoods and intermediate hoods. A disadvantage of this arrangement is that the user does not have a clear view of the actuating elements and must therefore feel them. In addition, actuators that are attached in this way are exposed to high levels of pollution from vapors and vapors.

The invention is therefore based on the object of providing a solution in which these disadvantages of the prior art can be eliminated or at least reduced in a simple manner and with a simple construction of the operating device and the extractor hood.

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

The extractor hood solves the problem by the characterizing features of claim 1. Unless otherwise stated, directional information, such as front, rear, top or bottom, is understood in relation to an operating device which is mounted in the underside of an extractor hood with the open side of the outer housing facing downward

In the context of the present invention, a control unit device is understood to be a device which, on the one hand, has 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 module. Such extractor hoods are, in particular, undercounter hoods, intermediate hoods or flat screen hoods. The part of the extractor hood in which the suction opening is provided for sucking in vapors and vapors is referred to as a fan module. 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 accommodated in the fan module. In extractor hoods, in particular in the case of undercounter hoods, intermediate hoods or flat screen hoods, the fan module is integrated in a kitchen unit, in particular in one of the wall units of the kitchen unit, or is attached between two wall units and clad to the front. In particular in the case of intermediate hoods and undercounter hoods, the front of the fan module is not visible to the user.

The control device of the extractor hood according to the invention has an outer housing and at least one inner housing. The outer housing is in this case a component which is fixed to the housing, that is to say can be fixedly mounted on the extractor hood and in particular on the fan module. In this context, permanently installed means that the outer housing cannot be moved with respect to the extractor hood when it is installed. However, it is within the scope of the invention and it is preferred that the outer housing is detachably connected to the extractor hood, that is to say from the latter can be removed. The outer housing is preferably accommodated in the extractor hood in such a way that only one side lies in an outside of the extractor hood or adjoins the latter. 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 a part of the inner housing. The other sides of the outer housing can represent closed walls. However, at least passage openings for fastening the inner housing are preferably provided in the further walls. In addition, the side of the outer housing facing away from the open side can also be open, so that the outer housing merely forms a frame. The open side of the outer housing is preferably the underside of the outer housing in the assembled state of the operating device. The inner housing can be moved out of the outer housing and inserted into it via the open side. The open side therefore has an opening that corresponds to the size of the inner housing. In one embodiment, only the lower edge of the side walls of the outer housing can be present on the open side. However, it is also within the scope of the invention to provide a collar or flange on the open side. This is particularly advantageous for the assembly of the control unit device on the extractor hood.

The inner housing is fastened to the outer housing and at least temporarily received in the outer housing. In particular, the inner housing is preferably accommodated in the outer housing in such a way that one of the sides of the inner housing lies in the open side of the outer housing or adjoins it. The open side of the outer housing is preferably the side of the outer housing that lies in the outside, in particular the underside of the extractor hood. The inner housing is movably attached to the outer housing. In this context, a movable fastening is understood to mean a fastening which allows the inner housing to move relative to the outer housing without the connection to the outer housing being released or removed. Here, at least a part of the inner housing is moved with respect 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 about at least one guide element, which can represent, for example, a damping element or an acceleration element.

At least one control element with at least one actuating element for at least one function of the extractor hood is held at least in regions on the inner housing. The control unit is particularly preferably accommodated in the inner housing. In this case, at least part of one side of the operating part lies in one side of the inner housing, preferably in the front of the inner housing. The side of the inner housing, in which at least part of 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. The actuating element or the actuating elements of the operating part are preferably provided on the side of the operating part, which lies at least partially in one side of the inner housing. 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 represents a button, a button or a slide. According to the invention, the electrical, electronic and / or mechanical system is preferably also incorporated in the operating part, which is influenced by the function of the extractor hood, which is caused by actuating the actuating element. To influence the function, the inner housing is not moved according to the invention. At most, part of the control unit, in particular an actuating element, is moved in the control unit.

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. An operating state is a state in which at least one of the actuating elements of the control panel is accessible to the user of the extractor hood. The state of rest is the state in which at least part of the actuating element is at least partially received in the extractor hood and is therefore not accessible to the user.

By in the present invention, the outer housing is fixedly connected to the extractor hood and an inner housing movably held therein is provided for receiving and firmly holding the control panel, the relative position of the Inner housing and thus the control panel to the extractor hood can be changed. This makes it possible, at least at times, to bring the operating part at least partially into the viewing area and thus into the area of intervention of the user. Such a change in position is only possible with the embodiment of the control unit device according to the invention. In contrast to the present invention, for example in the case of a slide which is provided on the extractor hood, only the actuating element, that is to say the slide, is movable relative to the extractor hood. The guide in which the slide is held and which can be compared to a housing according to the present invention, however, is fixedly connected to the extractor hood.

In addition, the construction of the control unit device according to the invention has the advantage that the overall construction of the extractor hood is simplified. In particular, only a fixed connection is required between the extractor hood and the outer housing and between the control unit and the inner housing. Such connections can be realized in a simple manner, for example by providing an opening on the extractor hood, into which the outer housing can be received and held by fastening means such as latching lugs. A structural change of the extractor hood is therefore not necessary. Control panels must also be fastened to a part of the extractor hood in all applications and for this purpose generally have fastening means, for example in the form of locking lugs. For a firm connection of the operating part in the inner housing, at least one latching opening is thus only to be provided in the inner housing, into which this latching lug can engage. A structural change to the control panel is therefore also not necessary. This further simplifies the manufacture of the extractor hood.

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

According to a preferred embodiment, the control panel is completely accommodated in the outer housing in the idle state and / or the control panel protrudes at least in regions from the outer housing in the operating state.

In the assembled state of the control unit device in an extractor hood, in the idle state the control unit is preferably located in the extractor hood in such a way that it does not protrude beyond one of the outer sides, for example the underside of the extractor hood. In the idle state, the control part is particularly preferably located completely in the extractor hood. The outer housing is preferably located in the extractor hood in such a way that its open side lies in one of the outer sides, preferably in the underside of the extractor hood. In this embodiment, the control unit is in the idle state in the outer housing so that it does not protrude beyond its open side. If, on the other hand, the outer housing is arranged on the inside of the extractor hood on the outside of the extractor hood, the operating element can, in the idle state, protrude beyond 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 operating 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 which corresponds to the offset of the open side of the outer housing to the outside of the extractor hood , protrudes. In the idle state, the inner housing is preferably completely accommodated 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 unit protrudes, at least in some areas, beyond the underside of the extractor hood. 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 extractor hood that its open side in one of the outer sides of the extractor hood, in particular the Underside of the extractor hood, or is arranged offset inwards in the extractor hood to this outside, the operating part in the operating state protrudes at least partially beyond the open side of the outer housing. Since the control unit is held firmly in the inner housing, the inner housing also projects in the operating state, at least in regions, beyond the open side of the outer housing.

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

In the operating state, the control unit preferably protrudes so far beyond the outer housing and beyond the outside of the extractor hood that the actuating element (s) on the control unit protrude beyond the outside of the extractor hood. As a result, the user can actuate the actuating element or elements in 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. In this way, the actuating elements can be protected against contamination in the vapors and vapors.

According to an embodiment not according to the invention, the inner housing is rotatably connected to the outer housing. A connection in which the inner housing can execute a rotational movement in relation to the outer housing is referred to as a rotatable connection. Here, the rotation of the inner housing relative to the outer housing is preferably limited to a predetermined angular range. In addition, the twisting or rotating is preferably carried out about an axis which is parallel to the open side of the outer housing. The rotation or rotation of the inner housing relative 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 control unit 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 operating device is simplified and, on the other hand, the operating device can also be held securely in the operating position in which it is opposite the Outer housing is pivoted, can be guaranteed. Furthermore, in the case of a rotatable connection between the inner housing and the outer housing, it is possible to unscrew the operating part far enough 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 extending beyond the outer housing must stand out. The surface of the control panel, which in the installed state of the control panel device in the operating state extends beyond the outside of the extractor hood, in particular the underside of the extractor hood, is minimized. This also minimizes the risk of contamination.

According to an embodiment not according to the invention, 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 provided in the rear region, preferably on the rear side of the outer housing and inner housing in the lower region, that is to say in the vicinity of the open side of the outer housing. As a result, the front of the inner housing can be pivoted out of the outer housing without the rear of the inner housing having to be pivoted upward in the outer housing. An advantage here is that the installation space required for the control panel device is reduced, and yet the largest possible part of the front of the inner housing and thus the control panel can be pivoted out of the outer housing. This means that larger control elements can also be used on the control panel.

The axis of rotation is preferably formed by a partial axis formed on the inner housing and a partial axis formed on the outer housing. In addition, elastic elements are provided on the inner housing or the outer housing, via which the partial axes are kept aligned with one another. These elastic elements can be tabs, for example. The advantage of this embodiment is on the one hand the reduction in the number of parts required for the operating device. In particular, a separate metal pin, which is otherwise used as an axis, can be omitted. In addition, the assembly of the control panel device is simplified.

According to the invention, 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. Because the inner housing is slidably connected to the outer housing relative to the outer housing, a translational movement can be carried out by the inner housing. The advantage of this embodiment consists in particular in the simple design of the connection 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 released in a simple manner if necessary, for example for maintenance purposes. This simplifies the manufacture and maintenance of the control unit device.

The control unit is preferably held firmly in the inner housing. In this case, a connection between the inner housing and the operating part is designated as firmly held, which prevents a relative movement between the inner housing and operating part in the assembled state of the operating part device. For maintenance purposes or for cleaning, however, the control panel can preferably be removed from the inner housing. The connection between the inner housing and control panel is therefore preferably detachable. For the purposes of the invention, holding in the inner housing is understood to mean an arrangement and mounting of the operating part in which at least one, preferably at least four sides of the operating part are surrounded by walls of the inner housing. In the following, the side on which the at least one actuating element is provided is referred to as the front of the operating part. Side surfaces are understood to be the surfaces of the operating part which adjoin the front and which are inclined to the front and preferably arranged perpendicularly thereto. The control panel is preferably at least partially surrounded by walls of the inner housing on at least two, particularly preferably on four of the side surfaces. By holding the control panel firmly in the inner housing, but preferably releasably connected to it, maintenance and, if necessary, replacement of the control panel can be carried out in a simple manner. At the same time, an uncontrolled displacement of the control unit in the inner housing can be prevented by the fixed mounting of the control unit in the inner housing.

According to the invention, at least one acceleration element is provided in the connection between the inner housing and the outer housing. An element is understood to be provided in the connection that can influence the connection between the inner housing and the outer housing. The actual holding 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 against one another in one of the directions of movement. The acceleration element is preferably a spring element, for example a leg spring or a roller spring. Since the movement of the housing relative to one another is supported by the acceleration element, the handling of the control device is made easier for the user. In one embodiment, the acceleration element is provided in such a way that it supports the movement of the inner housing out of the outer housing, that is to say the movement from an idle state into an operating state. In an alternative or additional embodiment, the acceleration element supports the movement of the inner housing into the outer housing, that is to say the movement from the operating state to the idle state.

At least one damping device is preferably provided in the connection between the inner housing and the outer housing. An element is understood to be provided in the connection that can influence the connection between the inner housing and the outer housing. The actual holding 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 holding the inner housing on the outer housing. A damping device is a preferably multi-part device that slows down a relative movement of the two housings relative to one another at least in one direction, that is, counteracts the movement of the housings in this one direction. By providing at least one damping device, for example, an uncontrolled falling down or pivoting of the inner housing in the outer housing can be prevented.

According to one embodiment, the damping device consists of a damping element and a damping structure interacting with it. The damping element can 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 can represent a rotatably mounted gearwheel with damping about the axis of rotation of the gearwheel. The damping element is preferably a component that is separate from the two housings. As a result, the structure of the two housings can be kept simple, and yet an uncontrolled relative movement can be prevented.

The damping structure is preferably formed on the outer housing or the inner housing. This means that the damping structure can be introduced into the housing, for example cut out, 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 interacts with a damping structure, in particular a tooth structure, on the outer housing, preferably in one of the side walls of the outer housing. However, the arrangement can also be implemented the other way round, in that the damping element is provided on the outer housing and the damping structure, in particular tooth structure, is provided on the inner housing.

At least one locking mechanism is preferably provided in the connection between the inner housing and the outer housing. A mechanism is understood to be provided in the connection that can influence the connection between the inner housing and the outer housing. The actual holding 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 holding the inner housing on the outer housing.

The latching mechanism preferably comprises a latching element and a latching geometry for guiding the latching element. The latching element is preferably molded onto the outer housing or the inner housing. A device is used here as a latching element, which is also referred to as a latching element referred to, which fixes the relative position of the two housings to one another at least temporarily. The relative position of the two housings with respect to one another is particularly preferably fixed in the rest position and / or the operating position by the latching element. A separate latching element and an associated latching geometry are preferably provided for each position. The latching element preferably interacts with at least one latching geometry that allows the latching connection to be released and guided into the latching position. The latching element can represent, for example, a triangular or diamond-shaped dome on one of the housings. The latching geometry preferably represents a structure, in particular a heart curve backdrop. By using such a latching mechanism, the temporary fixed relative position of the housings can be released in a simple manner. In addition, the latching mechanism can be provided in the interior of the control unit device, since a pressure exerted on the inner housing from the outside is sufficient to actuate such a latching mechanism.

According to a preferred embodiment, at least the damping structure is made in one piece on one of the housings. This means that the damping structure is molded onto the housing or, for example, introduced into a housing wall. In addition, the locking element is preferably made in one piece with one of the housings, that is to say integrally formed on one of the housings. The latching geometry preferably represents a separate component to the housings or is incorporated in such a separate component. The separate component is preferably connected to one of the housings 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 an embodiment not according to the invention, the operating device comprises an outer housing and an inner housing rotatably held therein. The control panel is fastened to the side walls in the inner housing by means of fastening means. The axis of rotation lies in the rear lower region of the inner housing and the outer housing and is parallel to the open side of the outer housing. A damping structure in the form of a partially circular tooth structure is introduced in at least one of the side walls of the outer housing. In addition, in at least one of the side walls of the outer housing there is at least one passage for attaching and gripping one Guide element provided with a locking geometry in the form of a heart curve backdrop. A passage for a damping element in the form of a gearwheel with a rotary damper is provided on the inner housing on at least one side wall, and such a damping element is fixed in the passage. The damping element is fastened to the inner housing in such a way that it engages with the damping structure of the outer housing and can run along it. In addition, a latching element, in particular in the form of a diamond-shaped dome, is integrally formed on at least one side wall and can be brought into engagement with the latching geometry of the guide part, which is clipped onto the outer housing. 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 of which rests either on the outside of the rear wall of the inner housing or, in the case of a rearwardly open inner housing, at the top of the lower wall. The two housings are rotatably connected to one another via a divided axis, at least one partial axis being formed on the inner housing and one partial axis on the outer housing. The leg spring is attached to the axle. A spring structure is formed in the front of the outer housing, which comes into contact with the front upper edge of the inner housing when the inner housing is pivoted and is pressed forward by the latter. The spring structure has an inward projection which counteracts the unwanted pivoting of the inner housing.

In this embodiment, the inner housing can be pivoted out of the outer housing with the operating part by pressing against the underside of the inner housing from below. As a result of this pressure, the latching element is guided in the latching geometry in such a way that it can emerge from it below. The movement downwards, i.e. in the operating state, is supported by the leg spring. The damping element that runs along the damping structure slows down this movement. Shortly before the operating state is reached, the front upper edge of the inner housing comes into contact with the spring structure on the outer housing and presses it forward. After passing the projection on the spring structure, the front edge lies on a holding edge which is formed under the spring structure in the front of the outer housing. The spring structure with the retaining edge can thus be referred to in the sense of the invention as a further locking geometry and the front upper edge of the inner housing, which is preferably rounded, as a further locking element will. To return to the idle state, the inner housing is pressed from the bottom up. The spring force of the spring structure of the outer housing is overcome. The dome then engages with the heart curve backdrop 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 comprises an outer housing and an inner housing which is held displaceably in the vertical direction. The control panel is fastened to the side walls in the inner housing by means of fastening means. A passage for a damping element in the form of a gearwheel with a rotary damper is provided in at least one of the side walls of the outer housing and such a damping element is fixed in the passage. In the rear of the outer housing there is a passage for attaching and gripping through a guide element with a locking geometry in the form of a heart curve backdrop. At the front of the outer housing, a passage is provided in the lower region for holding one end of a roller spring. A damping structure in the form of a vertical tooth structure is introduced on at least one side wall of the inner housing. The damping element is fastened to the outer housing in such a way 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, is integrally formed on the back of the inner housing, which can be brought into engagement with the latching geometry of the guide part which is clipped onto the outer housing. Finally, an acceleration element in the form of a roller spring is provided, the free end of which is fastened in the passage in the lower region of the front of the outer housing. The rolled-up part of the roller spring is rotatably mounted in a receptacle in the top of the inner housing. The roll axis of the roll spring is horizontal.

In this embodiment, the inner housing with the operating part can be moved downward out of the outer housing by pressing against the underside of the inner housing from below. As a result of this pressure, the latching element is guided in the latching geometry in such a way that it can emerge from it below. The downward movement, i.e. in the operating state, is supported by the roller spring. The damping element that runs along the damping structure slows down this movement. When the operating state is reached, the damping element hits the holding edge provided at the upper end of the steam structure. A 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 the bottom up. The spring force of the scroll spring is counteracted. The dome then engages with the heart curve backdrop and is guided into a latching position and the inner housing is thus held in the rest position.

The control unit device is preferably arranged in the extractor hood in such a way that the open side of the outer housing lies in one of the outer sides of the extractor hood. The open side is particularly preferably located in the underside of the extractor hood or is at least introduced into the underside of the extractor hood in such a way that the operating part of the control unit device in the operating state protrudes beyond the underside of the extractor hood to such an extent that the user touches the actuating element (s) from the front Control panel can access.

An advantage of an extractor hood with the control unit device is that both the operating aspects can be taken into account and contamination of the actuating elements can be largely prevented. In addition, the construction of such an extractor hood is simple, since no separate brackets and guides for the control panel have to be attached to the extractor hood itself. The entire mechanism for connecting the control panel to the extractor hood and for moving the control panel with respect to the extractor hood are integrated in the control panel device according to the invention. This is preferably detachably connected to the extractor hood and represents a preassembled unit that only has to be inserted into the extractor hood.

According to the invention, it is also possible to arrange the control device on the extractor hood in such a way that the open side of the outer housing, via which the Inner housing can be moved with the control panel, is in an upper side of the extractor hood or one of the side walls of the extractor hood. In these embodiments, the extractor hood can be, for example, a so-called cooker or other extractor hood that is freely attached to the wall or in the room and has a viewing hood with a chimney connected above it.

However, the extractor hood preferably represents an extractor hood with a 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 an upper cabinet of a kitchen or clad with a kitchen front. With these extractor hoods, which are also referred to as undercounter hoods or intermediate hoods, there is nothing to be seen from the front when the extractor hood is installed. Thus, the use of an operating device according to the invention, in particular in the case of such hoods, has the advantage that the actuating element can be protected against contamination by being pushed into or swung into the outer housing. On the other hand, the operating elements can be visible to the user in the operating state and can be operated by him in a simple and reliable manner.

According to the invention, the operating part therefore protrudes in an operating position at least in regions over the underside of the extractor hood, preferably over the underside of the fan module.

In Figure 1 A side view of a fan module 10 of a first embodiment of an extractor hood 1 is shown schematically. The fan module 1 can also be referred to as a vapor screen or viewing hood of the extractor hood 1 and in particular represents the lower part of an extractor hood 1. Above the fan module 10 there is generally an exhaust air duct. The fan module 10 in the Figure 1 is shown without cladding. Such a fan module 10 can be integrated into an upper cabinet of a kitchen unit or can be provided with a covering and then serve as the lower part of a cooker. In the fan module 10, the suction opening of the extractor hood 1 is preferably introduced, through which vapors and vapors are sucked into the interior of the extractor hood 1.

In the underside of the extractor hood 1, in particular the fan module 10, an operating device 2 is introduced. The control panel device 2 is in the embodiment according to Figure 1 at least partially pivotable relative to extractor hood 1, in particular fan module 10, that is to say rotatable. In particular, part of the operating device 2 can be pivoted downward beyond the underside of the fan module 10.

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

The state in which the operating part 22 in the inner housing 21 is pivoted downward beyond the underside of the fan module 10 is referred to as the operating state or operating position and is shown in FIG Figure 1 shown. How out Figure 2 that shows a schematic front view of the fan module 10 according to the embodiment of the extractor hood 1 Figure 1 with the control device 2 in the operating position, is in the operating position of the control device 2 on the front of the Control unit device 2, an actuating element 23 of a control unit 22 held in the control unit device 2 is accessible to the user of the extractor hood 1.

If the control device 2 from the in Figures 1 and 2 When the operating position shown is pivoted upward, the control unit device 2 and thus also the actuating element 23 in the fan module 10 disappear. The underside of the control unit device 2 then lies flush with the underside of the fan module 10 in the so-called rest position or is slightly downwards relative to the underside of the fan module 10 or offset above.

The construction of an embodiment of the control unit device 2 which is not according to the invention will now be described with reference to FIG Figures 3 to 7 explained in more detail. In Figure 3 A schematic partial exploded view of a first embodiment of an operating device 2 is 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. An operating part 22 is held in the inner housing 21.

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

A damping structure 241 of a damping device 24 in the form of a part-circular tooth structure is introduced into the side wall 202 of the outer housing 20. In addition is In the side wall 202 of the outer housing 20, a passage is provided for fastening and gripping through a guide element 261 of a latching mechanism 26. The guide element 261, which is designed as a separate component, has in the lower region in the in FIG Figure 3 on the side facing the outer housing 20 has a locking geometry 262 in the form of a heart curve backdrop (see Figure 5 ).

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

The inner housing 21 which can be inserted into the outer housing 20 is rotatably held 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.

A passage for a damping element 240 of the damping structure 241 in the form of a gearwheel with a rotary damper is provided on the inner housing 21 on the side wall 210. The damping element 240 is attached by clipping from the inside through the side wall of the inner housing 21. The damping element 240 is fastened to the inner housing 21 in such a way that it engages with the damping structure 241 of the outer housing 20 and can run along it. In addition, a latching element 260 is formed on the side wall 210 in the form of a diamond-shaped dome, which can be brought into engagement with the latching geometry 262 of the guide element 261, which is clipped onto the outer housing 20. The latching geometry 262, in particular the heart curve backdrop together with the latching element 260, in particular the dome, takes over the latching function of the control unit device 2 and in particular of the two housings 20, 21 against one another. When pressed against the inner housing 21 from below, the dome moves in the heart curve backdrop, 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 on the edge, which comes into contact with the front upper edge of the inner housing 21 when the inner housing 21 is pivoted and is pressed forward by the latter. The spring structure 204 has an inward projection (not visible), which counteracts the unwanted pivoting of the inner housing 21 upwards.

An operating part 22 is inserted into the inner housing 21 from the front. This also has a box shape in the illustrated embodiment. In the illustrated embodiment, locking lugs are provided on the side walls 220 of the operating part 22 as fastening means 221 for fastening the operating part 22 in the inner housing 21. On the front of the control unit 22, actuating elements 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 control unit device 2 comprises an acceleration element 25, which according to the embodiment in FIG Figure 3 represents a leg spring.

In Figures 4 to 7 is the internal structure of the control panel device 2 according to Figure 3 shown in more detail. In the Figures 4, 5 and 7 the inner structure is shown in the rear area. The inner housing 21 is shown here in a completely biting position which is pivoted downward by 90 °. In the rear lower region of the inner housing 21, tabs 280 are provided on the side walls of the inner housing 21 and extend in the width direction of the inner housing 21. The length of the tabs 280 is, however, less than the width of the inner housing 21. In the middle of the rear lower area of the inner housing 21, a partial axis 28 is provided in the middle of the underside of the inner housing 21, which also extends in the width direction of the inner housing 21.

Two partial axes 27 are provided on the inside of the rear wall of the outer housing 20 and, in the embodiment shown, are held on the rear wall of the outer housing 20 via webs. In the assembled state, the partial axis 28 of the inner housing 21 lies in one axis with the divided axis 27 of the outer housing 20. The two axes are also held relative to one another by the tabs 280, which engage on the divided axis 27 of the outer housing 20. The rotational movement of the two housings 20 and 21 relative to one another thus takes place via this divided axis 27, 28. The resilient elements, which in the embodiment shown as Tabs 280 are formed, the inner housing 21 clips the inner housing 21 and rotates about the divided axis 27 of the outer housing 20. The advantage of this concept is that there is no need for an extra metal pin, which is normally necessary for the rotational movement. This would result in more complex assembly and additional costs. The structurally divided axis 27, 28 according to the preferred embodiment implements the function of the metal pin in the outer and inner housings 20, 21. The assembly is kept very simple by the clipping.

In addition, in Figure 5 the position of the acceleration element 25, which represents a leg spring in the embodiment shown. The leg spring is placed on the axis 28 of the inner housing 21. One leg of the acceleration element 25 lies against the inside of the rear wall of the outer housing 20 and the other leg lies against the top of the lower wall of the inner housing 21.

The end position locking of the operating device 2 takes place in the illustrated embodiment via a further locking mechanism, which is formed by the spring structure 204, a holding edge introduced into the front of the outer housing 20 and the front upper edge of the inner housing 21. The spring structure 204 represents a resilient element which is formed in one piece in the front of the outer housing 20 with the outer housing 20 during manufacture. When the inner housing 21 is pivoted out of the outer housing 20, the spring structure 204 of the outer housing 20 is pushed away by the upper front edge of the inner housing 21, on which, for example, an outer circular element (not shown) can be molded, that is to say 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 counter pressure which is strong enough not to allow the operating part 22 to pivot back into the rest position, that is to say its initial position. Only when the pressure is somewhat higher does the resilient element 204 give way and the operating part 22 can then be pivoted with the inner housing 21 upwards into its initial position, that is to say the idle state.

In this embodiment, the operating device 2 thus comprises an outer housing 20 and the inner housing 21 rotating therein. When “tapped”, the latching element 260 leaves the latching geometry 262, which can also be referred to as the labyrinth guide of the guide piece 261. The control unit 22, which is clipped into the inner housing 21, is pivoted out, for example damped by a maximum of 32 °. The maximum swivel angle can be adjusted accordingly by design changes. For the accelerated rotational movement, the acceleration element 25, which can also be referred to as a pivot spring in the illustrated embodiment, is used, which is attached to the inner housing 21.

In Figures 8 to 13 An embodiment of the control device 2 of an extractor hood according to the invention is shown. This embodiment is an operating device in which the inner housing 21 can be displaced in the outer housing 20, that is to say carries out a translatory movement. How from the Figures 8 and 9 results, the control unit with the inner housing 21 is moved down in this embodiment in the vertical direction from the underside of the fan module 10.

In this embodiment too, the control device 2 consists of an outer housing 20, an inner housing 21 and a control part 22 accommodated in the inner housing 21 with actuating elements 23. The outer housing 20 has a box shape which is open at the bottom. Fastening means 201 are provided on the front and rear of the outer housing 20, via which the outer housing 20 can be introduced into a corresponding opening in the underside of the viewing hood 10 of the extractor hood 1. In this embodiment, a passage opening is provided in each of the side walls 200 of the outer housing 20, through which a damping element 24, which is implemented as a gearwheel with a rotary damper, can reach.

The inner housing 21 has a box shape open to the rear. In this case, through openings 212 for actuating elements 23 of the operating part 22 are made in the front of the inner housing 21. Longitudinal slots are provided in the side walls of the inner housing 21, one of the longitudinal edges of the slots being separated 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. A retaining edge 213 is formed at the upper end of the slot.

The height of the inner housing 21 is higher than the height of the operating part 22, which can be inserted into the inner housing 21 from behind. 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 in the form of a roller spring can be used. The coil or coil of the roller spring is held in this receptacle 29, for example via a shaft. The free end 250 of the roller 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 locking element in the form of a triangular geometry. This extends from the rear of the inner housing 21 to the rear and can thus be brought into engagement with a locking geometry 262 of a guide element 261, which is provided through the rear of the outer housing 20.

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

The two housings 20 and 21 are locked against one another by means of the locking mechanism 26, which comprises the locking element 260 and the locking geometry 262. The latching element 260, which represents a triangular geometry, moves as in FIG Figure 13 can be seen in the heart curve geometry of the rotating guide piece 261. The inner housing 21 is held once in the middle of the heart curve. At the next "tap", it is led out on the other side of the heart curve due to the bevelled outer edge of the guide piece 261 and the inner housing 21 thereby moves downward.

The acceleration of the inner housing 21 is realized with the help of the roller spring. The T-section of the roller spring is held in the outer housing 20 and the roller spring is tensioned by the upward movement of the inner housing 21.

According to the invention, a rotationally and / or translationally functioning control unit device for fold-out or extendable control parts is thus provided. Advantages include a haptic, comfortable, non-motorized, inexpensive solution that can be installed in the smallest possible space, which can preferably be triggered by tapping.

Significant advantages of the present invention include that, if necessary, there is a clear view of the control panel, that the actuating elements, which can also be referred to as control buttons, do not stick out, especially when not in use, and the resulting increase in comfort when using a fan module. Finally, less contamination of the actuating elements than in previous actuating elements is to be feared in the present invention.
