Description

The present invention is an extractor hood device having at least one housing device and at least one displaceable Wrasenleiteinrichtung at a suction for vapor. The invention further relates to a method for operating a cooker hood device.

Hoods are often used in the kitchen above a cooking area, such as a stove or hob or a cooktop, to suck in the ascending boiling vapors and filter out its fat components and / or odors and / or to remove the fumes to the outside of the kitchen. For this purpose, hoods on a suction for vapors, through which the ascending from the cooking area vapor is sucked by means of a fan in the hood.

It is advantageous if the largest possible proportion of Wrasens z. B. is passed above a hob to the suction, where the vapor can then be sucked. This is usually achieved by a Wrasenleiteinrichtung, the so-called Wrasenschirm, the hood over which the vapors is collected and directed to the suction of the hood.

Such a vapor shield should advantageously provide as large an area as possible to catch the ascending vapor when using the extractor hood. Furthermore, when using the extractor hood, a vapor shield should be positioned as close as possible above the point from which the vapor rises. If the cooker hood is not needed, a large-area and / or tightly positioned above the cooking area Wrasenschirm is impractical and visually less appealing. In particular, when in an apartment, the kitchen area and the living area freely adjoin or merge into one another, kitchen appliances such as an extractor fan should often attract attention as little as possible.

Therefore, cooker hoods have been known with Wrasenschirmen that can be extended before or during use of the hood and then retracted again. Here, the Wrasenschirme can be manually and mechanically supported or automatically by means of a motor and retracted.

From the DE3822510A1 is a hood with a fan housing, a horizontally displaceable on or in the blower housing guided Wrasenauszug and a switching device for manual or automatic fan control, in which the Wrasenauszug for selective automatic pull-out control with a motor drive device is disconnectably connected. Furthermore, from the DE102005060356A1 a drive mechanism for a trigger system with an extendable Abzugsschirm known, which is movable via a drive motor between an extended and a retracted position.

From the EP2233842A2 a drive arrangement for a viewing screen of a fume extraction device is known, via which the viewing screen can be moved relative to a housing of the extractor device and having a spring element and a lever unit. From the DE19825324A1 an extractor hood is known with an automatically extendable by spring means flat screen for selectively increasing the extractor cross-section over a hob. Furthermore, from the DE102011084414A1 an extractor hood is known, which has a fume hood housing and a relative to the extractor hood movable extension screen, wherein at least one scroll spring is provided to support the displacement of the pull-out screen.

A disadvantage of motorized or spring-assisted moveable Wrasenschirmen is that the Wrasenschirm, in order to be movable in a horizontal plane, must be exposed on its front or in the extension direction. As a result, the vapor canopy is always visible. When installed in kitchen cabinets extractor hoods that means that the Wrasenschirm in the retracted position or in the non-operating position below the furniture body or below the front panel of the furniture body protrudes down so that the vapor shield can then be extended below the front panel of the furniture body forward.

However, this has disadvantages in the overall appearance of a kitchenette, since the upper cabinets with their front panels then have no uniform final lower edge, because the hood, or at least but their Wrasenschirm, due to the design down.

From the DE4142475C2 is a hood in the form of a flat-panel hood with extendable into the working position, front filter is known, which is installed in a wall unit line, the hood is lowered to the height of the front filter and the latter forward extendable. Further extractor hoods, which are adjustable in height, are from the DE3920558A1 and the DE202005004307U1 known. By the applicant sold under the name DAR 3000 Absenkrahmen for Extractor hoods is an adjusting device for lowering and lifting an extractor hood, in which an adjustable in its strength power storage in the form of a gas spring is used. This is also in the hitherto unpublished patent application DE12401046.3 described. The disadvantage here, however, is that only the displacement in height is supported mechanically or motor. The extension and retraction movement of the vapor shield must be carried out manually.

It is therefore an object of the present invention to provide an extractor hood device which, compared with the cited prior art, offers an alternative possibility for the automatic displacement of the vapor shield relative to a housing device, with which at least one of the abovementioned disadvantages is eliminated.

A further object of the invention is in particular to provide an extractor hood device available, in which the Wrasenschirm in a structurally simple way can be automatically extended and retracted so that the vapor canopy in the retracted position is visually unobtrusive by being in the retracted position can be hidden in the housing of the hood or behind a front panel of a furniture body.

Another aspect of the invention is to provide a method of operating such a cooker hood device.

This object is achieved by an extractor hood device having the features of claim 1 and by a method having the features of claim 17. Preferred developments of the invention are the subject of the respective subclaims. Further advantages and features of the invention will become apparent from the embodiments.

The extractor hood device according to the invention comprises at least one housing device, and may also comprise at least one fan device and at least one filter element. Further, at least one Wrasenleiteinrichtung is provided on at least one suction area for vapors, wherein the Wrasenleiteinrichtung is arranged relative to the housing means between at least a first position and at least a second position and vice versa. For displacing the Wrasenleiteinrichtung while at least one displacement device is provided, on which the Wrasenleiteinrichtung is added. The displacement device comprises according to the invention a biasing device, a motor device and a coupling device, and is suitable and adapted to displace the Wrasenleiteinrichtung in the vertical and / or horizontal direction.

Under a Wrasenleiteinrichtung according to the invention in particular to provide an approximately plate-shaped panel, which is generally known as Wrasenschirm. The Wrasenleiteinrichtung but may additionally comprise a the plate-like or panel-like vapor shield associated fireplace-like housing part for the transmission of Wrasens.

The extractor hood device according to the invention has many advantages. A significant advantage is first that the Wrasenleiteinrichtung not manually, but motorized and thus automatically retracted and extended. Another advantage is that a combination of the motor device with a biasing device, which will be explained in more detail below, in a structurally simple way a displacement of the Wrasenleiteinrichtung in different directions is possible. It is not excluded according to the invention that the Wrasenleiteinrichtung also or additionally by hand can be moved in and out. For this purpose, a suitable coupling or decoupling system can be provided, which decouples the Wrasenleiteinrichtung of the engine device.

According to a preferred embodiment, the displacement device is suitable and designed to displace the Wrasenleiteinrichtung both in the vertical and in the horizontal direction. Thus, the Wrasenleiteinrichtung is three-dimensionally displaceable by the displacement device.

A three-dimensional displacement of the Wrasenleiteinrichtung is understood in particular a not exclusively planar displacement of the Wrasenleiteinrichtung in a plane. Rather, the Wrasenleiteinrichtung can be moved in at least two levels. It is particularly preferred that the Wrasenleiteinrichtung in the installation situation, for example from the non-operating position at least partially downwards and at least partially forward to an operating position is movable. In order to enable a displacement or retraction and extension of the Wrasenleiteinrichtung, the motor device can be preferably operated in two directions.

Another considerable advantage is thus that the three-dimensional displacement of the Wrasenleiteinrichtung an extractor hood device is provided, which can be used better in different installation situations. It is particularly possible that an extractor hood device according to the invention z. B. is installed in a kitchen cabinet, the lower edge of the front panel of the kitchen cabinet then flush with the lower edge of the hood and in particular with the lower edge of the Wrasenleiteinrichtung. This will be done allows the Wrasenleiteinrichtung can be lowered first from a Nichtbetriebsstellung down into an intermediate position and then extended to the front in an operating position by the three-dimensional displacement of the Wrasenleiteinrichtung. This provides an optically appealing installation situation.

The at least one biasing device is preferably provided to assist the extension of the Wrasenleiteinrichtung or even completely effect. When retracting the vapor shield, the biasing device can absorb or dampen the retraction.

Particularly preferably, at least two biasing means are provided, of which in particular the one adjacent to the left portion of the Wrasenleiteinrichtung and the other adjacent to the right portion of the Wrasenleiteinrichtung is arranged. The at least two biasing devices expediently have the same force, so that a uniform extension and retraction of the Wrasenleiteinrichtung is guaranteed.

Preferably, the at least one biasing device is arranged or accommodated in a substantially pivotable manner on the housing device of the extractor hood device. In this case, the Wrasenleiteinrichtung is particularly preferably arranged or received pivotably on the housing means of the hood device. Appropriately, the biasing device can also be arranged within the Wrasenleiteinrichtung and arranged pivotally together with this on the housing means of the hood device. The at least one biasing device and / or the Wrasenleiteinrichtung can be suitably compared to the housing means by an angle between 1 ° and 90 °, preferably about 10 °, 20 °, 30 ° or 45 ° in particular pivoted downwards.

By the coupling device of the displacement device, an operative connection between the motor device and the Wrasenleiteinrichtung is preferably prepared. In advantageous embodiments, the coupling device is designed as a traction means, which is particularly flexible. In this case, the traction means may be formed as a belt, rope or chain. Preferably, the traction means can be wound on a shaft associated with the motor device.

According to an advantageous embodiment, the traction means wound on the shaft holds the Wrasenleiteinrichtung in the first position, which is a Nichtbetriebsstellung, for example, until the engine device is activated and the traction device unwinds from the shaft, whereby the Wrasenleiteinrichtung released and displaced, for example down to an intermediate position is from which it, for example, by means of the at least one biasing device in a second position, which is for example an operating position after is shifted forward. In this case, the Wrasenleiteinrichtung is displaced by the biasing device as long as the engine device is in operation and the traction means is unwound from the shaft.

In the reverse direction, ie when moving the Wrasenleiteinrichtung from the second position to the first position, the motor device is activated so that it rotates the associated shaft in the other direction, so that the traction means is wound up again on the shaft. As a result, the Wrasenleiteinrichtung is displaced against the force of at least one biasing device, for example, first backwards to an intermediate position and shifted from this back up.

Preferably, at least one deflection device, which can be designed, for example, as a rotatably mounted shaft, and in particular as a guide shaft, is provided for the coupling device. Thus, it is achieved in a simple manner that the force of the engine device can be exerted by means of the coupling device in particular as a pulling force on the Wrasenleiteinrichtung.

Particularly preferably, the shaft associated with the motor device and / or at least one deflection device is arranged above at least one pretensioning device in order to achieve a particularly advantageous and reliable transmission of power from the motor device via the coupling device to the Wrasenleiteinrichtung.

The coupling device may also be designed as a rack or a perforated strip, which cooperates with at least one gear assigned to the motor device to allow a displacement of the Wrasenleiteinrichtung.

According to a preferred embodiment, at least one biasing device is designed as a compression spring and in particular as a gas pressure spring and thereby particularly reliable, durable and low maintenance. In addition, when displacing the Wrasenleiteinrichtung against the spring force and a damping can be achieved.

In expedient and preferred embodiments, the motor device is set up and designed to provide a stronger force than the spring force of at least one biasing device. The force of the motor is preferred in particular stronger than the sum of the spring forces of all biasing devices used. Thus, the Wrasenleiteinrichtung by means of the motor device is also against the spring force of the at least one biasing device displaced, in particular, thus at least one biasing device is tensioned by the motor device again.

In order to enable the displacement of the Wrasenleiteinrichtung from the first to the second position and vice versa, and in particular the retraction and extension of the Wrasenleiteinrichtung, with substantially the same speeds, the motor device can be operated with at least two different voltages and / or speeds particularly preferred , Thus, for example, the motor device has to apply a lower force when the Wrasenleiteinrichtung is extended, since the extension is effected or assisted, for example, essentially by the pretensioning device and / or by gravity. In contrast, the motor device, for example, when retracting the Wrasenleiteinrichtung not only apply force to retract the Wrasenleiteinrichtung, but in addition to overcome the spring force of the biasing means and the biasing devices and to tighten them again. Therefore, when retracting the Wrasenleiteinrichtung a higher electrical voltage and / or speed of the engine device is required to allow the retraction and extension of the Wrasenleiteinrichtung at the same speed.

According to one embodiment, the at least one pretensioning device has a locking device which secures the pretensioning device in a chipped state. As a result, the force of the biasing device can be selectively released and used for the displacement of the Wrasenleiteinrichtung. Thus, by means of the locking device, for example, a relaxation of the biasing device can be prevented, as long as the Wrasenleiteinrichtung in the first position, which is, for example, the Nichtbetriebsstellung is.

In order to enable the retraction or extension of the Wrasenleiteinrichtung to a predetermined position, the displacement device comprises at least one limit switch. In this case, such a limit switch particularly preferably determines the retracted end position, which is the non-operating position.

To the extension and retraction of Wrasenleiteinrichtung z. B. by pressing a button, in particular by means of a remote control, the displacement device is assigned in preferred developments at least one control device. Such a control device can, for. B. activate the displacement device with respect to the extension and retraction of Wrasenleiteinrichtung. In this case, the control device can preferably interact with the at least one limit switch. Such a control device can particularly preferably also define the end positions of the vapor guiding device over a time control. It can be z. B. be preprogrammed that the second position, for example, the operating position of the Wrasenleiteinrichtung is reached when the engine device z. B. 5, 10, 15, 20, 30 or even more or less seconds in operation. Retracting can also be made possible via such a time control. The control device may be separate Control device may be provided. However, it can also be integrated into a control device which also controls the other functions of the extractor hood, such as the blower device.

In a further, particularly preferred embodiment, the extractor hood device is designed such that it is suitable for installation inside or below a carcass device of an upper cabinet. In particular, the Wrasenleiteinrichtung is formed in the installed state of the hood in the first position, which, for example. the Nichtbetriebsstellung is to complete flush with a front panel of the body device, wherein the Wrasenleiteinrichtung is particularly designed to complete in the first position with its lower edge aligned with a lower edge of the front panel.

A considerable advantage is that it is thus possible to accommodate the cooker hood device essentially completely in the carcass device of the upper cabinet, wherein at least in the first position and the Wasenleiteinrichtung is substantially completely received in the carcass device of the upper cabinet and thus optically substantially no longer perceptible , Thus, a particularly attractive appearance of a cooker hood device in a kitchen cupboard is made possible.

According to a further preferred embodiment, the extractor hood device is designed such that the Wrasenleiteinrichtung, in the installed state of the hood device in the first position, which, for example. the non-operating position is to terminate flush with its lower edge with a lower edge of the housing device of the extractor hood device. Thus, the Wrasenleiteinrichtung is when it is in the first position, substantially completely received in the housing means, and thereby optically substantially imperceptible.

The inventive method is suitable for operating an extractor hood device with a housing device and a Wrasenleiteinrichtung at a suction for vapor, wherein by means of a displacement device, the Wrasenleiteinrichtung is displaced relative to the housing means between at least a first position and at least a second position and vice versa. According to the invention, the displacement device comprises a biasing device, a motor device and a coupling device, wherein the Wrasenleiteinrichtung by means of the displacement device in the vertical direction and / or in the horizontal direction, and in particular three-dimensional, is displaced.

In this case, according to the invention, three-dimensional shifting means in particular the displacement of the vapor-conducting device in at least two planes. Thus, it is in particular possible to shift the Wrasenleiteinrichtung at least partially downwards and then extend to the front.

The method according to the invention also offers many advantages, as have already been described above for the extractor hood device according to the invention.

It is particularly preferred that when moving from the first position to the second position, the motor device together with the coupling device displaces the Wrasenleiteinrichtung, in particular in the vertical direction, from the first position to an intermediate position that in the intermediate position, the biasing device is released, and that the biasing device displaces the Wrasenleiteinrichtung, in particular in the horizontal direction, from the intermediate position to the second position.

Further advantages and features of the present invention will become apparent from the embodiment, which will be explained below with reference to the accompanying figures.

In FIG. 1 one sees in a purely schematic side sectional view of a hood extraction device 1 according to the invention, which is installed in a wall unit 100. In this case, the extractor hood device 1 is substantially completely received in the body device 21 of the upper cabinet 100. In particular, the Extractor hood device 1 below substantially flush or aligned with the lower edge 23 of the front panel 22 of the upper cabinet 100 from.

The extractor hood device 1 comprises a housing device 2 and a in the FIG. 1 not shown blower device and also not shown in detail filter element.

The intake region 6 for vapor is associated with a vapor guide device 5, which is accommodated by means of a displacement device 9 on the housing device 2 of the extractor hood device 1.

FIG. 2 shows in an enlargement, the lower portion of the extractor hood device 1 in the upper cabinet 100 according to the FIG. 1 , In FIG. 2 It can be seen that the displacement device 9 comprises a motor device 11 which has a shaft 14 with a coupling device 12 wound thereon and constructed as a traction means 13. The traction means 13 is in the embodiment shown here, a flat belt, which is guided over deflecting means 15 designed as guide shafts to Wrasenleiteinrichtung 5 and is received there. In other embodiments, the traction means 13 may be formed as a rope, chain or the like. In other embodiments, the coupling device 12 may also be z. B. be provided by a rack drive available.

The Wrasenleiteinrichtung 5 is included in the embodiment shown here with two biasing devices 10 on the housing device 2 of the hood hood device 1, wherein in the sectional view shown here only one biasing device 10 can be seen. The biasing device 10 is provided by a compression spring 16, which is designed here as a gas pressure spring 17 available.

A limit switch 19 is used to detect that the Wrasenleiteinrichtung 5 has reached a certain position, in this example, the first position, which is the non-operating position 8, and for switching off the engine means 11 when the Wrasenleiteinrichtung 5 is in said position. Thus, on the one hand the retracted end position or the non-operating position 8 can be optimally defined, in addition, an overload of the motor 11 is avoided.

In FIG. 3 is shown purely schematically how the Wrasenleiteinrichtung 5, which is designed here as Wrasenschirm 25, is first moved from the first position, in this case the non-operating position 8, in an intermediate position. For this purpose, the motor device 11 is activated by means of a control device 20, whereby the shaft 14 rotates and the rolled up thereon Flat belt 13 is handled. By releasing the flat belt 13, the vapor shield 25, in this example due to gravity, falls from the housing device 2 downwards, so that the vapor shield 25 is located below the lower edge 23 of the front panel 22 of the upper cabinet 100. This is made possible by the fact that both the vapor shield 25 and the pretensioning devices 10 are pivotally accommodated on the housing device 2 of the extractor hood device 1.

Like that Figures 3 and 4 can be seen, the Wrasenleiteinrichtung comprises in the example shown, a first part 27 which is pivotally received or mounted on the housing means 2, and a second part 26 which is telescopically movable relative to the first part 27. The biasing device 10 is arranged between the first part 27 and the second part 26 of the Wrasenleiteinrichtung. Now is the Wrasenleiteinrichtung 5 in the in FIG. 3 shown intermediate position, and the flat belt 13 is further unwound by the still activated motor device 11 of the shaft 14, the trained as a gas spring biasing device 10 and thereby extend by its compressive force the second part 26 of the Wrasenleiteinrichtung 5 relative to the first part 27 telescopically until the in FIG. 4 shown position, which is the second position or the operating position 7, is reached. The extension of the Wrasenleiteinrichtung 5 and the Wrasenschirms 25 is carried out so depending on the unwinding of the flat belt 13 of the shaft 14 of the motor device eleventh

Upon reaching the extended end position of Wrasenleiteinrichtung 5 and the operating position 7, the engine device 11 z. B. be deactivated via a timer. That is, e.g. the control device 20 starts the motor device 11 for a predetermined time, which meanwhile rolls exactly the length of the flat belt 13 from the shaft 14, which is required to move the Wrasenleiteinrichtung 5 in the operating position 7. In other advantageous, not shown embodiments, the end position in the operating position 7 can also be defined by a limit switch.

When retracting the Wrasenleiteinrichtung the motor device 11 is operated in the reverse direction, whereby the flat belt 13 is rolled back onto the shaft 14. As a result, the vapor shield 25 is first pulled backwards by means of the flat belt 13 via the deflecting devices 15, that is to say the second part 26 is retracted telescopically relative to the first part 27 of the vapor shield 25 until the in FIG. 3 shown intermediate position is reached. This is done against the spring force of the biasing means 10, so that they are thereby tightened again.

Since the motor device 11 is still activated and the flat belt 13 continues to wind on the shaft 14, the pivotally received on the housing device 2 Wrasenschirm 5 upwardly shifted to the non-operating position 8, as shown in FIG. 2 is shown. In this position, the engine device 11 is turned off by means of the limit switch 19.

In order to allow an equal speed when extending and retracting the vapor shield 25, it may be advantageous to operate the engine device 11 with two different electrical voltages and / or rotational speeds. Against the spring force of the biasing means 10, a higher motor force is required than when extending the Wrasenleiteinrichtung 5, since the extension by means of the spring force of the biasing means 10 takes place.

The activation of the motor device 11 for displacing the vapor guiding device 5 can be effected by the control device 20, which responds to a user input or to a sensor signal. The user input can be made, for example, on an operating device, not shown in the figures, of the extractor hood device 1, wherein the operating device can also be a remote control assigned to the extractor hood device. The sensor signal can originate from a sensor, not shown in the figures, which, for example, monitors the operating state of the cooking zones of a cooking surface arranged below the extractor hood device.

As a result of the three-dimensional displacement of the vapor guiding device 5 according to the invention, it becomes possible to receive the extractor hood device 1 substantially completely in the body device 21 of the upper cabinet 100. In particular, the extractor hood device 1 can be flush with the lower edge 23 of the front panel 22, whereby an optically appealing appearance of the extractor hood device 1 in the upper cabinet 100 can be achieved.

In other advantageous embodiments, it is also conceivable that the Wrasenleiteinrichtung 5 can be additionally displaced by hand from the non-operating position 8 in the operating position 7. Then it may be necessary to decouple at least parts of the displacement device 9, so that the Wrasenleiteinrichtung 5 can be pulled out by hand down and then forward.
