[0012] The term "intended" means specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function means that the object fulfills and / or executes this specific function in at least one application and / or operating state.

[0013] It is further proposed that the locking unit comprises at least one hinged element for at least one hinged movement to change a locking state, in particular at least one of the locking states mentioned above. Advantageously, the locking state can be changed particularly efficiently, and in particular, the movement of the locking unit to change the locking state can be advantageously simplified.

In particular, the at least one hinged element is provided for the hinged movement to change the locking state, at least between the closed and the operational locking state. Preferably, the at least one hinged element is provided for opening to change the locking state, in particular from the closed locking state to the operational locking state.The at least one hinged element is preferably designed to fold down to further change the locking state, in particular from the ready-to-use locking state to the closed locking state. Preferably, the at least one hinged element is arranged in a folded-down position in the ready-to-use locking state and / or in the closed locking state, particularly in the removal position and / or in a closed position. The at least one hinged element is preferably arranged in an open position in the ready-to-use locking state, particularly in a ready-to-use position. The folding movement is preferably designed as a folding movement of the at least one hinged element relative to a reference point, particularly on the locking unit.The folding movement can be configured as a folding movement of at least one folding element relative to a movement support unit of the locking unit. Preferably, the locking unit has at least two, and in particular exactly two, folding elements. The folding movement is preferably a folding movement of the at least two folding elements relative to each other. The folding elements are preferably identical to each other and, in particular, arranged symmetrically to each other with respect to a folding axis of the folding movement. Alternatively, the folding elements can be configured for an asymmetrical folding movement relative to each other with respect to the folding axis, wherein, in a given locking state, a folding element can, in particular, have a different deflection relative to the folding axis than another folding element.The folding elements, in particular their respective principal planes of extension, are preferably arranged at least substantially parallel to each other in the folded position. "Substantially parallel" here refers in particular to an alignment of a direction and / or plane relative to a reference direction and / or reference plane, wherein the direction and / or plane has a deviation from the reference direction and / or reference plane of preferably less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. An internal angle between the folding elements is preferably less than 8°, advantageously less than 5°, and particularly advantageously less than 2° in the folded position.Alternatively, the at least one hinged element can be arranged in an open position in the ready-to-use closed state and / or in the closed closed state, particularly in the removal position and / or in a closed position, and in particular may have an angular deflection, especially an inner angle, greater than 8°, for example with respect to the reference point on the motion support unit and / or the other hinged element.

Alternatively, it would be conceivable that the folding element, in the operational closed state, in particular in the operational position, is arranged in the folded-down position.

[0014] Furthermore, it is proposed that the hinged element be designed so that a ventilation duct, in particular the one mentioned above, passes through at least a portion of the hinged element in its operational closed state. Advantageously, the ventilation duct can be particularly efficiently limited, and the ventilation can be advantageously guided. Preferably, the hinged element has at least one recess through which the ventilation duct passes in the operational closed state. Preferably, in the operational closed state, a ventilation duct is provided only through the at least one recess of the at least one hinged element. Preferably, in the operational closed state, at least one hinged element blocks any ventilation duct that runs outside the at least one recess of the at least one hinged element.Preferably, at least one exhaust vent path in the operational closed state runs through the respective recess of the at least two hinged elements. Preferably, the at least two, and in particular exactly two, hinged elements provide at least two, and in particular exactly two, exhaust vent paths, wherein the exhaust vent paths can run behind the two recesses in a respective flow direction, in particular away from each other, for example, in a mirror image with respect to the hinge axis.

[0015] Furthermore, it is proposed that the filter unit comprises at least one filter element integrated into the hinged element. In particular, the filter element can advantageously be moved simultaneously with the hinged element and, in particular, removed from the exhaust duct. Advantageously, the fastening of the filter element, at least in the closed, ready-to-use state, within the exhaust duct can be simplified, especially by securing the filter element in the exhaust duct by means of the hinged element. The filter element is preferably received and, in particular, secured in the recess of the hinged element. In the closed, ready-to-use state, the exhaust path runs, in particular, through the at least one filter element.The closure unit and the filter unit are preferably designed so that the exhaust air path, when closed and ready for operation, passes through the at least one filter element. Advantageously, this allows for a particularly compact and efficient design for closing the exhaust air opening, filtering the exhaust air, and limiting the exhaust air path. In the maintenance state, the filter element can be removed from the hinged element, for example, with the aid of tools, and is particularly reusable or replaceable for maintenance purposes, such as cleaning and / or replacement. The filter element is preferably plate-like, with at least one edge region of the filter element being clamped by the hinged element and / or positively and / or frictionally connected to it. The filter element can be rigid or a film.The filter element is preferably integrated into a mounting frame of the hinged element and, in particular, is fixed to it in a manner that prevents movement. A "fixed connection" and / or a "fastening" of two elements shall be understood to mean, in particular, that the elements are not movable relative to each other in any direction and, in particular, are always connected to each other in the same orientation and arrangement.

[0016] It is further proposed that the hinged element has at least one, in particular the at least one mentioned above, closing flap, which is fixedly connected to the filter element, at least for changing the closed state. Advantageously, the filter element can be positioned, particularly within the exhaust duct, to change to the operational closed state by a corresponding movement of the closing flap, at least from the exhaust opening, and in particular by opening the exhaust opening in the operational closed state. Advantageously, the complexity of the design can be reduced, and in particular, the movement of the filter element and the hinged element to change the closed state can be simplified, especially by reducing the number of moving components. Preferably, the at least one hinged element has exactly one closing flap.The hinged element comprises, in particular, the locking flap and the mounting frame, which are connected to each other in a manner that prevents movement. The at least one locking flap is preferably designed to allow movement of the at least one hinged element, and in particular of the two hinged elements relative to each other, based on the hinge movement, to change the closed state.

[0017] Furthermore, it is proposed that the filter element include a grease filter, which allows for particularly efficient filtering of grease from the extractor hood, especially from the extracted fumes. Advantageously, maintenance efficiency and / or safety can be increased, particularly by reducing or preventing grease deposits in ventilation ducts, especially the extractor hood duct, downstream of the grease filter. In particular, the risk of grease fires can be reduced and efficient extraction operation can be advantageously ensured. The filter element, especially the grease filter, can include a non-woven mat and / or a metal mesh, or be designed as such. Preferably, the filter element is designed as the grease filter.Alternatively or additionally, the filter element may have another type of filter that appears useful to the expert, for example an odor filter, in particular a carbon filter, or the like.

[0018] Furthermore, it is proposed that the closure unit comprises a motion support unit, in particular the one mentioned above, and that the filter unit comprises at least one collection tray, which are formed integrally. Advantageously, a particularly compact design, and in particular increased cost-efficiency, of the exhaust system can be achieved. In particular, the filter performance of the filter unit can be improved. The motion support unit and the at least one collection tray are preferably formed integrally. Preferably, the motion support unit and the collection tray are part of the same component, in particular, a component formed in one piece. The motion support unit is preferably designed to support at least one movement, in particular the folding movement and / or a translational movement, of at least the closure unit and the filter unit.Preferably, the movement support unit is designed to support at least one hinged element. The drip tray is preferably designed to collect at least some grease, for example, dripping from the grease filter, and can in particular be designed as a grease drip tray. The drip tray is preferably arranged below the filter element in at least one closed position, and in particular in every closed position. Alternatively or additionally, the drip tray can be designed to collect at least one liquid, in particular condensation and / or a liquid flowing through the exhaust system, especially in the closed position when ready for operation. The filter unit preferably has at least two, and in particular exactly two, drip trays, which are advantageously arranged below each respective filter element in at least one closed position.Preferably, the collection trays are formed on opposite sides of the hinge axis.

[0019] It is further proposed that the folding element be pivotably connected to a motion support unit of the locking unit, in particular the aforementioned one, thereby providing particularly advantageous support for the folding movement. Advantageously, a movement of the motion support unit, in particular a translational movement, correlates with at least one movement, in particular a translational movement and / or the folding movement, of the folding element. The motion support unit preferably has at least one pivot joint element, preferably exactly two pivot joint elements, in particular on a base surface of a collection basin of the collection tray. The pivot joint element is preferably connected to the folding element at least in the closed position, and in particular in every closed position. Preferably, exactly one pivot joint element is connected to exactly one folding element.The folding element preferably has a counter-rotating joint element, which, particularly when connected to the rotating joint element, forms a pivot joint with the rotating joint element. The counter-rotating joint element is preferably located at one end, particularly at the lower end relative to an installation position, of the folding element. The rotating joint is provided to enable the folding movement, which preferably proceeds along an axis of rotation of the rotating joint. The folding movement preferably proceeds along a fixed axis of rotation. The folding element preferably has only one degree of freedom relative to the motion support unit. Preferably, the folding element is designed to be separable from the motion support unit, particularly at least from the rotating joint element, especially for cleaning and / or emptying and / or replacing the filter element and / or the collection tray, particularly at least in the maintenance state.Alternatively, it is conceivable that the folding element is always connected to the motion support unit.

[0020] Furthermore, it is proposed that the locking unit comprises a motion support unit, in particular the one mentioned above, and at least one motion guidance unit, wherein the motion guidance unit has at least one cam slot or at least one cam block for guiding the folding movement when the motion guidance unit moves relative to the motion support unit. Advantageously, the folding movement can be provided in a particularly simple, reliable, and / or cost-effective manner. In particular, the number of components required to provide the folding movement and / or the number of separate movement sequences of components of the locking unit relative to each other for providing the folding movement can be reduced. The motion guidance unit is preferably designed to guide the folding movement along the, in particular, respective axis of rotation of the at least one pivot joint of the locking unit.The motion guidance unit is preferably movable, in particular by means of the at least one cam slot or the at least one cam block, and connectable to the at least one folding element, preferably to both folding elements, and in particular connected in every closed state. The folding element preferably has a cam block or cam slot configured opposite to the cam slot or cam block of the motion guidance unit, which is in particular positively engaged with the cam slot or cam block of the motion guidance unit, at least for guiding the folding movement. The motion guidance unit is preferably designed to guide each folding element to the folding movement. Preferably, the motion guidance unit has a cam slot or cam block for each connected, in particular guided, folding element.The locking unit preferably comprises exactly one motion guidance unit, in particular one formed in one piece and / or as a single component. Alternatively, the locking unit can have more than one motion guidance unit, in particular with more than one cam slot or cam block, connected to more than one, in particular one each, hinge element, each of which is connected to the motion support unit. The cam slot, in particular the motion guidance unit, preferably has at least one curvature to guide the hinge movement. The motion guidance unit is preferably curved at least in sections, in particular to provide the curved cam slot. Preferably, the motion guidance unit is designed to release or lock the hinge movement, in particular depending on the position of the motion guidance unit relative to the motion support unit.Preferably, the motion guidance unit is designed to hold the at least one folding element in the folded position for at least one position of the motion guidance unit relative to the motion support unit. The motion guidance unit is preferably designed for a movement, particularly linear, relative to the motion support unit, to provide, and in particular guide, the folding movement. The motion guidance unit is preferably designed for only one movement, particularly linear, relative to the motion support unit, to provide, and in particular guide, the folding movement.Preferably, the locking unit is designed to move at least one folding element, in particular the cam block of the folding element, for the, in particular linear, movement of the motion guidance unit relative to the motion support unit along the cam slot, in particular along the curvature of the cam slot, of the motion guidance unit, and thus in particular to guide the folding element along the folding movement. Alternatively, it would be conceivable that the motion guidance unit is designed to guide the folding movement in a manner that appears sensible to a person skilled in the art, different from a cam control, and / or that the motion guidance unit is designed to guide the folding movement in a manner that differs from a linear movement relative to the motion support unit.

[0021] Furthermore, it is proposed that the extractor hood have an at least partially electrically movable drive unit, in particular at least one drive unit for the overall movement of the locking unit relative to the mounting plate, to change the locking state. In particular, ease of use can be advantageously increased, at least for changing the locking state, by means of the electric drive. Advantageously, the locking state can be changed by means of a particularly simple drive design and, in particular, a particularly simple movement. The overall movement of the locking unit is, in particular, a movement of the entire locking unit and, in particular, the filter unit integrated within the locking unit, preferably a movement of the entire extraction unit. The drive unit preferably has at least one electric motor.The electric motor can be designed as a linear motor. The drive unit preferably comprises at least one, for example, exactly one, end effector element of the electric motor. The end effector element is preferably designed as a movable part of the drive unit, particularly relative to the mounting plate. Preferably, the end effector element is configured to perform a movement, in particular a drive movement, corresponding to the overall movement, especially along the same axis of movement and advantageously along the same direction of movement as the overall movement. The drive unit, in particular the end effector element, is preferably configured to hold and / or support and, in particular, to contact at least one part of the locking unit in at least one, in particular in every, locking state.Preferably, the drive unit, in particular the end effector element, is designed to hold and / or support the motion support unit at least in the closed closure state and / or in the closure state ready for removal. The drive unit, in particular the end effector element, is preferably designed to hold and / or support the entire closure unit and, in particular, the integrated filter unit at least in the closed closure state and / or in the closure state ready for removal. The drive unit, in particular the end effector element, is preferably designed to support the motion guide unit at least in the closed closure state and / or in the closure state ready for removal, and, in particular, to hold and / or support it at least partially in the open closure state.The drive unit, in particular the end effector element, is preferably designed to drive the overall movement of the locking unit, at least for one change between the closed locking state and the ready-to-remove locking state. Preferably, the drive unit is designed solely for driving the overall movement for the change between the closed locking state and the ready-to-remove locking state. The drive unit, in particular the end effector element, is preferably designed to drive both the overall movement and a subsequent movement for a change between the closed locking state and the ready-to-use locking state. The subsequent movement is preferably based on a movement of the end effector element along the same axis of motion as the overall movement. Preferably, the subsequent movement follows directly from the overall movement.The subsequent movement preferably has the same mean direction as the immediately preceding overall movement. In particular, the end effector element is designed to perform a movement, preferably continuous and / or linear, for the change between the closed and operational closure states, which drives both the overall movement and the subsequent movement. The overall movement is preferably linear. The subsequent movement is preferably at least partially linear. The drive unit, especially the end effector element, is preferably designed for a linear movement, particularly only a linear one. The subsequent movement preferably differs from the overall movement at least by suspending a movement of the motion support unit.Preferably, the drive unit, in particular the end effector element, is designed to support the motion support unit for the folding movement, especially at least in the open closed position, against a support element, in particular of the extractor cooktop and / or the extractor hood, and in particular to position it on the support element. The support element can, for example, be designed as a support surface, in particular the underside of the extractor duct below the extractor opening. Preferably, the drive unit, in particular the end effector element, is decoupled from the motion support unit, in particular at least with respect to the overall movement, when the motion support unit is supported on the support element. For the support state, the motion support unit is preferably arranged in a fixed position relative to the support plate, in particular independently of any movement of the drive unit.The overall movement and the subsequent movement preferably differ from each other with respect to the support state of the movement support unit.

[0022] Furthermore, it is proposed that the drive unit be designed to propel the folding movement by means of a single drive, in particular the one mentioned above, which further propagates the overall movement. Advantageously, the folding movement can be provided by only a single drive movement, whereby a change between the respective locking states can be provided by only one drive movement. In particular, the drive unit can be designed to be particularly simple, compact, and / or cost-efficient. The drive unit, in particular the end effector element, is preferably designed to move the motion guide unit into the supported position opposite the motion support unit for the folding movement.The locking unit is preferably designed to convert the linear movement of the drive unit, in particular the end effector element, into the rotary folding movement of the at least one folding element. Preferably, the locking state, in particular each locking state, can be changed and, in particular, achieved by a single drive movement of the drive unit, in particular the end effector element.

[0023] Furthermore, it is proposed that the locking unit have at least one operating element for manually changing at least one state from a locked state, particularly the one mentioned above. The operating element is preferably provided for manual changes from the ready-to-remove locked state to a state removed from the exhaust duct, particularly the maintenance state.

[0077] Alternatively, it is conceivable that the motion guidance unit 36a has at least one cam block (not shown) for guiding the folding movement when the motion guidance unit 36a moves relative to the motion support unit 28a.

[0078] Alternatively, it would be conceivable that the motion guidance unit 36a is designed to guide the folding movement in a manner that appears sensible to a person skilled in the art, different from a cam control, or / or is designed in such a way that the motion guidance unit 36a is designed to guide the folding movement in a movement different from a linear movement relative to the motion support unit 28a.

[0086] The overall movement is designed as a shutdown relative to the mounting plate 72a, corresponding to the change between the closed locking state and the operational locking state (see...). Figures 2 and 3 ).

[0087] The subsequent movement is linear (cf. Figures 3 and 4 The end effector element 50a is intended for the further movement to a shutdown relative to the mounting plate 72a.

[0088] The end effector element 50a is designed to perform a continuous linear movement in addition to the overall movement and the subsequent movement during the change between the closed closure state and the operational closure state (see Figures 2 to 4The end effector element 50a is designed to perform a continuous shutdown between the closed closure state and the operational closure state.

[0089] The locking unit 12a is in the supported position during the further movement (cf. Figures 3 and 4 The motion support unit 28a is placed on the support element 58a in the supported position. The subsequent movement differs from the overall movement at least by the cessation of a movement of the motion support unit 28a.

[0090] The drive unit 30a is designed to drive the folding movement solely by means of a drive that propagates the overall movement. The drive unit 30a is designed to drive the folding movement solely by means of a linear drive movement.

The locking unit 12a is designed to convert the linear movement of the end effector element 50a into the folding movement of at least one folding element 22a.

[0092] Figure 5 Figure 10a shows the extractor hood in the ready-to-remove closed position. The locking unit 12a, in this ready-to-remove closed position, protrudes from the extractor hood opening 74a above the mounting plate 72a.

[0093] The extractor fan 10a can be transferred from the closed sealed state to the ready-to-remove sealed state (see Figures 2 and 5 ).

[0094] Figure 6Figure 10a shows the extractor hood in a maintenance state. The closing unit 12a and the integrated filter unit 14a are completely removed from the extractor duct 18a in this maintenance state.

Figure 7Figure 1 shows the locking unit 12a and the filter unit 14a in a disassembled state for maintenance, in particular for cleaning and / or replacing components of the locking unit 12a and / or the filter unit 14a. The hinge elements 22a and the motion support unit 28a are designed to be separable from each other in the maintenance state. The motion support unit 28a and the motion guide unit 36a are designed to be separable from each other in the maintenance state.

The operating element 52b is positioned in the deflected position in the ready-to-remove state. The operating element 52b can be deflected to change the closed locking state to the operational locking state.

[0105] The closed locking state and the locking state ready for removal differ in this case only by a deflection of the operating element 52b.

[0106] The control element 52b is designed to be manually deflected. The control element 52b is intended to allow the operator to change between the recording state and the deflected state by pushing and / or pulling the control element 52b.

[0107] Alternatively, the control element 52b can be designed to be deflected mechanically and / or by means of at least one further control element (not shown) and / or by means of another operating operation that appears sensible to a person skilled in the art.
