Description

The present invention relates to an extractor hood comprising at least one hood base body with at least one screen device. This screen device has at least one suction section with at least one suction opening. The screen device defines a predetermined screen area. The present invention also relates to a method for operating such an extractor hood.

Extractor hoods are often installed over hotplates in order to suck off the greasy vapors that rise during cooking and, in particular, to free them from fat.

So show the pamphlets FR 2 454 341 A1 and DE 10 2007 060 816 A1 an extractor hood with a first body arranged on a wall and a second body movable relative to the first body.

From the pamphlets FR 2 454 852 A1 , DE 29 14 862 A1 , FR 2 200 768 A5 and AT 325 256 A extractor hoods are known for arrangement on a kitchen wall cabinet, in which a front wall is pivotably attached to a frame.

Extractor hoods that are attached to the ceiling above the hob as island hoods instead of on the wall or a kitchen wall unit are from the publications EP 1 134 501 A1 , DE 10 2011 001 184 B4 and EP 2 249 087 A2 known.

In addition to the technical benefits of such extractor hoods, an extractor hood should also have a visually appealing design. However, it is a disadvantage, particularly in the case of large hobs or with extractor hoods that are far away from the hob, that the projection surface of the suction surface ideally spans at least the entire hob below. As a result, extractor hoods, in particular in the case of extractor hoods with a round cross-section of the filter surface or suction surface or with a round design, are often relatively large, which is not always optically advantageous.

It is therefore the object of the present invention to provide an extractor hood which can be made smaller.

This object is achieved by an extractor hood with the features of claim 1 and with a method for operating an extractor hood with the features of claim 12. Preferred developments of the invention are the subject matter of Subclaims. Further advantages and features of the invention emerge from the exemplary embodiments.

The extractor hood according to the invention comprises at least one hood base body with at least one screen device. The screen device has at least one suction section with at least one suction opening, the screen device defining a predetermined screen surface. Furthermore, at least one screen device and at least one vapor guiding device are arranged on the hood base body, the screen device and the vapor guiding device being displaceable at least from a rest position into an operating position. In the rest position, the screen device and the vapor guiding device are essentially in contact with the hood base body and in the operating position are at least partially spaced from the hood base body in order to provide an enlarged screen surface.

According to the invention it is provided, on the one hand, that the vapor guiding device is designed as a pivotable flap, which is received on the hood base body by means of a hinge device, wherein the vapor guide device or the hinge device is additionally mounted on the hood base body so that it can be moved translationally in the vertical direction in order to both pivot and to enable a translatory movement of the vapor guiding device in relation to the hood base body.

According to the invention, it is alternatively or additionally provided that at least two screen devices and at least two vapor guiding devices are provided, the screen devices at least substantially completely surrounding the hood base body in the rest position.

According to a preferred embodiment, the vapor guiding device is always arranged between the hood base body and a screen device, in particular in the rest position and / or in the operating position it is positioned closer to the hood base body than the screen device.

The extractor hood according to the invention is designed in particular as an island hood, the extractor hood or the hood base body or the shielding device preferably having a round or also an angular cross section. The screen device is defined according to the invention as the component or as the assembly against which rising vapors collide and via which vapors can be collected to an intake opening. The screen device or the hood base body alone provides a predetermined one Screen area available, which in particular does not cover the entire hob provided below the extractor hood.

The hood body preferably provides the housing of the extractor hood with all the necessary components. According to the invention, the hood base body can include the intake section and also the air discharge, for example a fan, filter devices and / or lines or channels.

The panel device is designed in particular as a decorative panel which is arranged around the hood base body and which essentially completely covers it, in particular in the rest position. In this case, the diaphragm device or, in the case of a plurality of diaphragm devices, are in particular arranged in an essentially form-fitting manner around the hood base body in the rest position. For this purpose, the screen device and / or the vapor guiding device are preferably adapted to the shape or the outer contour of the hood base body.

The vapor guiding device serves to deflect or guide the rising vapors to the suction section of the hood body when the screen surface is enlarged, i.e. when the screen device and the vapor guiding device are moved into the operating position, so that the vapors hitting the enlarged screen surface are sucked off effectively and reliably.

According to the invention, the diaphragm device and the vapor guiding device can be displaced jointly or simultaneously or also one after the other from the rest position to the operating position and vice versa. In particular, a motorized or a manual shift is possible. In particular, a displacement is to be understood as a method, a pivoting, a tilting, a displacement and / or a rotation.

The vapor device is preferably arranged on a side section of the hood base body. The screen device preferably covers the vapor guiding device in the operating position and / or the rest position.

In preferred refinements, the diaphragm device or the provided diaphragm devices are manufactured at least in sections from glass and / or stainless steel and / or other particularly high-quality materials. The vapor guiding device is preferably made of sheet metal, steel and / or plastic.

The extractor hood according to the invention preferably has no operating unit or at least no operating unit that is visible in the rest position. The extractor hood can then, for example, be coupled to the operation of a hob arranged underneath. In other configurations, an external operating unit can also be provided or an operating unit which is arranged on the hood base body and which is covered by the diaphragm device in the rest position. The shutter device can be opened, for example, by touching the shutter device or gesture recognition.

The extractor hood according to the invention offers many advantages. A considerable advantage is that an extractor hood with a particularly attractive appearance is made available which, depending on the configuration, is made relatively small when the screen device and the vapor guiding device are arranged in the rest position. The projection surface or the screen surface then preferably does not cover the entire hob arranged under the extractor hood.

In order to provide a sufficient screen area or an enlarged screen area for a hob provided under the extractor hood, the extractor hood or the screen area of the extractor hood can be enlarged during operation so that the projection of the screen area is adapted to the size of the hob below.

Preferably, the diaphragm device can be moved in a translatory manner and / or rotatably pivoted on the hood base body. It is particularly preferred here that the diaphragm device is moved in a translatory manner from the rest position into the operating position in a horizontal orientation. Depending on the configuration, however, the diaphragm device can also be moved or pivoted additionally or exclusively in a rotational manner before, after and / or during the translational movement.

Particularly preferably, the vapor guiding device can be moved in a translatory manner and / or pivoted on the hood base. It is particularly preferred that the vapor guiding device is pivotably received on the hood base body and is also provided such that it can be moved in a translatory manner in a vertical orientation. As a result, it is preferably possible to accommodate the vapor guiding device on the hood base body in such a way that the vapor guiding device cannot be seen in the rest position and is covered by the screen device. In the operating position is achieved by the special type of displacement of the vapor guiding device that this z. B. first pivoted outward and then shifted in the vertical direction downwards, so that the Vapor guiding device is moved at least in sections to the height of the screen device.

The at least one screen device and the at least one vapor guiding device are positioned in the rest position at a small distance from the hood body. The screen device and the vapor guiding device are preferably aligned approximately parallel to the surface of the hood base body. In particular, the diaphragm device and / or the vapor guiding device rest at least in sections on the hood base in the rest position.

In the operating position, the screen device is positioned at a distance from the hood base body. A vapor guiding device arranged between the hood base body and the screen device is at least partially spaced apart from the hood base body, in particular with a section and / or an edge, in the operating position. At the same time, the vapor guiding device, in particular with another section and / or another edge, can rest on the hood base body and / or be connected to it.

In expedient refinements, the vapor guiding device is connected to the diaphragm device at least in sections. In this context, connected is to be understood in particular to mean that the vapor guiding device is connected to the diaphragm device at least in sections. In particular, this configuration enables joint displacement to be achieved. In addition, a seal is created between the vapor guiding device and the screen device, so that vapor cannot pull through between the vapor guiding device and the screen device, but is instead guided via the vapor guiding device to the suction section of the hood base body. According to the invention, the screen device and the vapor guiding device can be displaced together. It is thus possible, for example, that when the screen device is moved apart or extended, the vapor guiding device is automatically extended along with it or is shifted from the rest position into the operating position.

For this purpose, the diaphragm device and the vapor guiding device preferably have a common drive so that the diaphragm device and the vapor guiding device can be moved jointly from one position to the other by means of a motor and, depending on the configuration, also fully automatically.

According to the invention, the vapor guiding device is designed as a pivotable flap. The flap is held on the hood body by means of a hinge device, wherein the vapor guiding device or the hinge device is then additionally accommodated on the hood body so that it can be moved translationally in the vertical direction in order to enable both pivoting and translational movement of the vapor guiding device in relation to the hood body. The flap can expediently be designed as a straight sheet metal. In this way, a vapor guiding device is made available in a particularly simple manner. Such a vapor guiding device is particularly suitable for use on an extractor hood with an essentially rectangular or rectangular hood base body. If the hood base body and / or the suction surface are essentially round, the vapor guiding device or the flap is preferably adapted to the contour or the basic shape of the hood base body.

One embodiment provides that the extractor hood has a force element which is designed in particular as a spring element, the force element being set up and designed to move the at least one vapor guiding device into the operating position with a restoring force. In the case of a vapor guiding device designed as a pivotable flap, at least one of the stop edges of the at least one vapor guiding device is moved into the operating position with the restoring force. This means that no active drive is required for the vapor guiding device. The vapor guiding device can be brought into the operating position simply by the passive drive of the power device.

One embodiment provides that the extractor hood has at least one, in particular motorized, drive. The drive is set up to move the at least one diaphragm device between the rest position and the operating position. In the case of an actively, in particular automatically, driven diaphragm device, the vapor guiding device can be moved back into the rest position against the restoring force. For this purpose, the drive of the diaphragm device is set up and designed to move a vapor guide device arranged between the diaphragm device and the hood base body into the rest position when the operating position is moved into the rest position, in particular against the restoring force of the force element. In doing so, the vapor guiding device is pushed by the aperture device. The vapor guide device slides along the screen device, at least with one edge resting on a sliding surface of the screen device. The sliding surface is preferably arranged on the inside of the diaphragm device.

The closing force generated by the drive and acting by the diaphragm device on the vapor guiding device and thus ultimately on the force element is greater than the restoring force counteracting the closing force.

According to the embodiment, the at least one vapor guiding device has two opposite stop edges which, in the rest position, have a large vertical distance and a small horizontal distance from one another. In the operating position, the two opposite stop edges have a small vertical distance from one another and a large horizontal distance.

At least when changing between the operating position and the rest position or vice versa, one of the stop edges of the at least one vapor guiding device rests on the at least one diaphragm device, in particular on a sliding surface of the at least one diaphragm device. It is also possible that one of the stop edges of the at least one vapor guiding device is connected to the hood base body, in particular via a bearing element.

The vapor guiding device is preferably designed to be flexible, at least in sections. For this purpose, for example, the vapor guiding device can be made of silicone at least in sections or comprise silicone. The flexibly designed vapor guiding device or a flexibly designed part of the vapor guiding device can be particularly advantageously connected to the hood body and / or the diaphragm device, so that a common movement or shifting of the vapor guiding devices is brought about into a suitable position. In particular, the translational method can also be effected in the vertical direction through a flexible configuration.

According to one embodiment, the vapor guiding device is connected to the hood base body, for example via a bearing element. This bearing element is preferably designed as a joint. Such a joint can be implemented by a flexible, ie elastic, section of the vapor guiding device. According to a further embodiment, the vapor guiding device is largely made of an elastic material, for example a cloth made of a fabric or a film, which in the operating position is stretched between the hood base body and the panel device and in the rest position is folded between the hood base body and the panel device or in the is received between the hood body, in particular rolled up.

According to the invention, at least two screen devices and at least two vapor guiding devices are provided, with the screen devices at least substantially completely surrounding the hood base body in the rest position. Here, the term “enclosing” means in particular covering or covering or cladding. In the rest position, the screen devices then preferably provide an essentially closed outer shell of the extractor hood or the hood base body. It is by essentially completely is to be understood in particular that the side sections and the front are enclosed by the screen device. Depending on the design, the extractor hood or the hood body can remain free at the top and bottom.

The extractor hood can also be designed with at least two screen devices and at least two vapor guiding devices, at least one vapor guiding device being arranged between the hood base body and each of the screen devices. This improves the detection of the rising vapors. It is also possible for the diaphragm devices to be evenly distributed over the circumference of the hood base body. This means that even vapor capture can be achieved on all sides of the extractor hood. In addition, the fastening and alignment of an extractor hood configured in this way, in particular an island hood, is simplified, especially when using a cable system. According to a particular embodiment, the screen devices are arranged on opposite sides of the hood base body.

In expedient refinements, the screen device and / or the vapor guiding device can be displaced into at least one service position. The screen device and / or the vapor guiding device can then preferably be displaced from a rest position essentially resting against the hood body into a position more remote from the hood base body, the operating position. According to the invention, the service position is a position of the screen device or the vapor guiding device which is even further away from the hood body or exposes the hood body even further than in the operating position. The diaphragm device can be shifted into the service position purely translationally, preferably in the horizontal direction. However, it is also possible that the diaphragm device is first moved in a translatory manner and is thus removed from the hood base body and is then pivoted in a rotary manner or is folded away upward. A user or a service employee can then reach the hood base body particularly easily for maintenance, repair or for replacing components. For example, the filters of the suction section can be exchanged or changed in the service position of the diaphragm device. For example, a lever for unlocking the filters from the suction section on the hood base body can be provided hidden by the screen device. This can then be easily reached in the service position. In addition, other filters, for example an odor filter or an activated carbon filter, can also be replaced in the service position.

At least one further suction opening is particularly preferably provided on at least one side section of the hood base body, the vapor guiding device essentially closing this suction opening in the rest position. Here is below Closing is understood to mean, in particular, a sealing or even a fluid-tight closing of the further suction opening. A further suction opening is made available, whereby the vapor guiding device on the one hand guides the rising vapor to the suction section of the hood body, but can lead into the further suction opening so that, depending on the design, an even more effective suction of vapor is possible.

The method according to the invention is suitable for operating an extractor hood as described above. The screen device and the vapor guiding device for operating the extractor hood are moved together from the rest position into the operating position in order to provide an enlarged screen area.

According to the invention, the vapor guide device is firstly designed as a pivotable flap, which is received on the hood base body by means of a hinge device, the vapor guide device or the hinge device being additionally received on the hood base body such that it can be moved translationally in the vertical direction, with the vapor guide device both pivoted and pivoted in relation to the hood base body is also moved translationally.

Secondly, according to the invention, at least two screen devices and at least two vapor guiding devices are alternatively or additionally provided, the hood base body being at least substantially completely enclosed by the screen device in the rest position.

The method according to the invention also offers the advantages already described for the extractor hood according to the invention.

The diaphragm device is preferably moved in a translatory manner, the vapor guiding device being moved in a translatory manner and pivoted in a rotational manner. In particular, the diaphragm device is moved in a translatory manner in a horizontal orientation. The vapor guiding device is preferably pivoted and moved in a translatory manner in the vertical direction. This achieves in particular that the screen surface is enlarged by moving the screen device apart and the vapor guiding device is preferably pivoted out at the same time as the screen device and is preferably shifted downward into the plane of the screen device.

According to the embodiment, the vapor guiding device is moved by a diaphragm device. It is provided in particular that the at least one vapor guide device slides along a sliding surface of the screen device during the movement of the vapor guide device. This makes it possible on the one hand that the distance between the Aperture device and the vapor guiding device is minimized, whereby the vapor line to the vapor inlet of the extractor hood is improved. On the other hand, it is thus possible for the vapor guiding device to be moved into the rest position, in particular against the restoring force of a force element.

Particularly preferably, the screen device and the vapor guiding device are automatically shifted from the rest position to the operating position and vice versa. Automatic is understood here, in particular, to mean that the panel device and the vapor guiding device can be moved in a motorized manner, so that the panel device and the vapor guiding device can be moved from the rest position to the operating position either at the push of a button or fully automatically, for example coupled to the control of a cooktop arranged under the extractor hood is made possible. A particularly uniform and attractive appearance of the extractor hood is achieved, in particular when the aperture device is closed or when the aperture device is closed. By automatically displacing the panel device and the vapor guiding device, it is possible, in particular when coupling to a hob, to provide the extractor hood even without an operating unit that is visible in the rest position. For example, an operating unit can be provided on the hood base body which cannot be seen when the panel devices are moved together. The hood can be put into operation, for example, by touching a panel device and can move apart so that the operating unit is released. However, it is also possible for the extractor hood to move apart when a cooking process is started on a hob or when the hob is switched on, so that an operating unit becomes free and / or the hood can still be controlled via the hob.

Further advantages and features of the present invention emerge from the exemplary embodiment which is explained below with reference to the accompanying figures.

In the Figures 1 to 6 a first embodiment of an extractor hood 1 according to the invention is shown purely schematically in different views, the extractor hood 1 being designed as an island hood and having a hood body 2 with a substantially rectangular cross section. The hood body 2 has on the underside a screen device 3 with a suction section 4, which has a suction opening 5.

Two diaphragm devices 7, which can be displaced between a rest position 9 and an operating position 10, are provided on the hood base body 2. In the rest position 9, the diaphragm devices 7 are essentially in contact with the hood base body 2. For this purpose, the diaphragm devices are adapted to the shape of the hood base body 2.

In the retracted position 9 of the screen devices 7, the suction section 4 of the screen device 3 provides a predefined screen surface 6.

In Figure 2 it can be seen that the diaphragm devices 7 have been displaced from the rest position 9 into the operating position 10, for which purpose they have been moved translationally in a horizontal orientation in the exemplary embodiment shown. By moving the As will be explained in the further figures below, an enlarged screen surface 11 is created, for which two vapor guiding devices 8 are arranged on the hood base body, which in the embodiment shown are each arranged on a side section 16 of the hood base body 2 and from the screen devices 7 are covered.

The ones in the Figures 1 and 2 Vapor guiding devices 8 that cannot be seen are displaced together with the screen devices 7, as a result of which the rising vapor is sucked in by means of the vapor guiding devices 8 to the central suction section 4 and through the suction opening 5 into the extractor hood 1.

Furthermore, an outlet 17 is provided on the upper section of the hood base body 2, through which the sucked-in air is blown back into the kitchen in the exemplary embodiment shown in a recirculation mode.

Figure 3 the previously shown extractor hood 1 is shown again, with the left panel device 7 removed. The view of the hood body 2 becomes clear, as a result of which the vapor guiding device 8 can now be seen on the left side section 16 of the hood body 2. Here the vapor guiding device is in the rest position 9, in which the vapor guiding device 8 rests on the hood base body 2.

In the exemplary embodiment shown, the vapor guide devices 8 are each designed as a flap 13, the flap 13 being made in sections from steel 19, but also comprising flexible material 18.

In Figure 4 the vapor guiding device 8 is shown in the operating position, the vapor guiding device 8 in the operating position 10 together with the extended screen device 7 providing an enlarged screen surface 11. Furthermore, in Figure 4 It is shown purely schematically that a further suction opening 15 is provided on each of the side sections 16, which are essentially covered or closed by the vapor guiding devices 8 in the rest position and are released at least in sections in the operating position 10.

In Figure 5 the illustration according to FIG. 4 is shown again in a front view. Here you can see the extended screen device 7 on the right-hand side and the extended or pivoted vapor guiding device 8 on the left-hand side. This view clearly shows that a smaller screen surface 6 is provided in the rest position 9 than in the operating position 10. The screen surface 11 enlarged in the operating position 10 by the extended screen devices 7 and the pivoted or moved vapor guide devices 8 provided.

In Figure 6 a side view of the side section 16 of the hood base body 2 is shown purely schematically, the vapor guiding device not being shown here, so that the view of a second or further suction opening 15 is enabled.

In the Figures 7 to 11 another embodiment of an extractor hood according to the invention is shown in different views.

The extractor hood 1 shown here comprises a hood base body 2 with a screen device 3, which has a suction section 4 with a suction opening 5. The hood base body has an essentially round cross-section and has a convex shape.

In Figure 7 it is shown that the screen devices 7 and the vapor guiding devices 8, which cannot be seen, are in contact with the hood base body 2 in the rest position 9. For this purpose, the screen devices 7 and the vapor guide devices 8 are adapted to the shape of the hood base body 2. In this position, a predetermined screen surface 6 is defined by the screen device 3.

In Figure 8 it is shown purely schematically that the screen device 7 and the vapor guiding devices 8 underneath, which cannot be seen, are shifted from the rest position 9 into the operating position 10, as a result of which they are further spaced from the hood base body 2. In this position of the vapor guiding devices 8 and screen devices 7, an enlarged screen surface 11 is provided.

In the exemplary embodiment shown, the screen device 7 and the vapor guiding device 8 are displaced essentially jointly and / or at the same time, for which purpose they have a common drive 12, which is not shown in detail in the figures. The motorized design or displacement of the panel devices 7 and the vapor guiding devices 8 also makes it possible, among other things, to automatically control the extractor hood or to couple it with the operation of a hob arranged underneath.

In Figure 9 the extractor hood 1 is shown purely schematically in the rest position 9 with only one screen device 7, which rests on the hood base body 2. By removing the screen device 7 on the left side, the view of the left Vapor guide device 8 free, which in the rest position 9 rests on the hood body 2.

In Figure 10 is the representation of the extractor hood 1 according to Figure 9 shown in the operating position 10. In this position, both the vapor guiding device and the screen device 7 are provided at a distance from the hood base body 2.

When comparing the Figures 9 and 10 or when comparing the vapor guiding devices 8 in these two figures, it becomes evident that the vapor guiding devices 8 are both pivoted and moved in a translatory manner in the vertical direction along the hood base body 2. In this way it is achieved that the lower edge 20 of the vapor guiding device 8 is approximately at the level of the screen device 3 in the operating position 10. The pivoting and displacement in the vertical direction also ensures that the vapor guiding device 8 does not protrude beyond the lower end of the screen device in the rest position 9 and is thus covered by the screen device 7.

In Figure 11 it is shown purely schematically that the right panel device 7 and, in the exemplary embodiment shown, the right vapor guiding devices 8 can also be moved into a service position 14 in addition to the rest position 9 and the operating position 10. Depending on the configuration, both sides can also be shifted into a service position 14.

In this service position 14, the diaphragm device 7 and / or the vapor guiding device 8 are provided even further away from the hood base body 2 than in the operating position 10 or release it even further. This ensures that a user can better access the hood base body 2, so that he or a technician can more easily remove components from the hood base body 2 and replace them during maintenance work. For example, it is also possible for the filter elements to be unlocked from the suction section 4 via a lever which is arranged on the side of the hood base body 2 and is hidden by the panel devices 7 during normal operation of the extractor hood.

Both embodiments shown do not have an operating unit. In the embodiments shown, operation is coupled to the operation of the hob arranged under the extractor hood 1. In other configurations, a dedicated operating unit can also be provided, which is then preferably arranged on the hood base body and is covered under the screen devices 7 in the rest position 9. The operating unit can then be released in the operating position 10 of the diaphragm devices 7, the movement of the diaphragm devices 7 being initiated using a suitable method.
