Description

The invention relates to an extractor device with a fume baffle plate and a lighting device.

In so-called downdraft systems, which are installed in the worktop and in which the extractor housing projects upwards over the worktop in which the hob is mounted, it is known to provide light sources at the upper end of the extractor housing. The hob is illuminated by the light sources, which are installed, for example, at a height of mostly between 20 and 40 cm.

A disadvantage of this type of lighting is that, on the one hand, the light sources are directly visible to the user and, on the other hand, the light sources are exposed to the vapors and vapors rising from the hob.

It is therefore the object of the present invention to create a vapor extraction device with a lighting device that does not have the disadvantages of the prior art and is nevertheless easy to assemble and handle.

The object is achieved according to the invention by an extractor device with an extractor housing, at least one fume deflector plate held detachably in the extractor housing and at least one lighting device which has at least one light source. The extractor device is characterized in that the fume guide plate is a light guide, that the lighting device is arranged below the fume guide plate, that the at least one light source faces the lower edge of the fume guide plate and that the lighting device is detachably attached to the fume hood housing.

A device for cleaning contaminated air, in particular vapors and vapors that arise during cooking, is referred to as an extractor device. The extractor device has an extractor housing. The suction opening through which air is sucked in is provided on the top of the cooker hood housing. The fume deflector plate is preferably at least partially accommodated in the extractor housing. For this purpose, the extractor housing preferably has a guide for the vapor baffle plate. In addition, the extractor housing has at least one retaining plate. The retaining plate can represent a side wall of the extractor housing or be fastened to the extractor housing, for example a side wall of the extractor housing.

The fume extraction device has at least one vapor baffle plate. A vapor guide plate is a surface element that directs the air, which is drawn in by a fan inside the vapor extraction device, to the suction opening of the vapor extraction device. Several vapor baffle plates can also be provided on the fume extraction device. In particular, a vapor guide plate can be arranged on the suction opening in front of and a vapor guide plate can be arranged behind the suction opening, in order to form a supply channel in front of the suction opening in the direction of flow. According to the invention, the vapor baffle plate is detachably held in the extractor housing. The vapor guide plate can be guided, for example, via vertical rails in the extractor hood. In addition, the fume deflector plate can be held from below in the extractor housing.

According to the invention, the at least one fume conducting plate represents a light guide. In particular, the fume conducting plate consists of a material that is suitable for conducting light. According to one embodiment, the vapor guide plate is made of glass, ie the vapor guide plate is formed by a pane of glass. The surfaces of the glass pane can be polished, as a result of which light which is introduced into the glass pane via one of the edges is reflected on the surfaces and is transmitted thereby.

A lighting device, which can also be referred to as a lighting device or light strip, is a device that emits light. According to the invention, the lighting device has at least one light source.

According to the invention, the lighting device is arranged below the vapor guide plate. In particular, the lighting device is arranged below the lower edge of the vapor guide plate.

Directional information such as top, bottom, front and rear and information such as width and height refer - unless otherwise specified - to an extractor device and its components in an assembled state. In particular, this information relates to an extractor device with at least one vapor deflector plate which is vertical, the extractor device being installed in a horizontal worktop behind a hob and extending behind it in the width direction of the hob.

The vapor deflector plate is preferably held in the extractor housing in such a way that it stands on the lighting device or in one small distance is positioned to the lighting device.

The light source faces the lower edge of the vapor baffle. This means that light from the light source can be introduced into the vapor guide plate via the lower edge of the vapor guide plate.

According to the invention, the lighting device is detachably fastened to the extractor housing. In particular, the lighting device can be fastened to a holding plate, to a side wall or to the bottom of the extractor housing.

With the present invention, an extractor device is thus created, by means of which light can be guided from below the vapor guide plate through the design of the vapor guide plate as a light guide in the upper area of the vapor guide plate. In addition, due to the detachable attachment to the extractor housing, the lighting device can be removed and, if necessary, repaired or at least replaced.

According to a preferred embodiment, the lighting device has at least two light modules, each of which includes at least two light sources. According to the invention, a light module is understood as meaning a separate structural unit which can be installed as a unit in the lighting device. The light sources are preferably arranged in a row in the light module. Thus, by arranging light modules in a row, a line of light sources can be generated, through which light can be introduced into the edge of the vapor guide plate. By providing at least two light sources in each case in the light module, assembly of the lighting device is simplified since each light source does not have to be integrated individually.

According to a preferred embodiment, the at least two light modules are detachably connected to one another. In particular, the light modules can be connected to one another via connection elements such as plugs. The light modules are arranged in a row one behind the other. Since the connection of the light modules is detachable, a single light module can be replaced in the event of a defect in a light module without having to replace the entire lighting device.

The lighting device preferably has a housing. The housing consists of a holding part and a cover part which are detachably connected to one another. The at least one light module is accommodated in the housing.

At least one opening for the passage of light is preferably provided in the cover part. When the lighting device is assembled, at least one light module is located in the housing below one of the openings. The light module can protrude through the opening at least in certain areas. However, the upper side of the light module preferably ends flush with the cover part in the area of the opening.

According to one embodiment, the light module comprises a module housing which consists of a transparent upper part and a lower part, with the light source in the light module facing the upper part. The top side of the module housing is the side that faces the vapor baffle plate when installed. The upper part and lower part of the module housing are preferably detachably connected to one another.

According to one embodiment, the edge of the vapor deflection plate that faces the lighting device has a roughened surface. The edge facing the lighting device represents in particular the lower edge of the vapor guide plate. Because this edge has a roughened surface, the light can diffusely enter the vapor guide plate and the output of the light can thus be homogenized via the vapor guide plate. In particular, distances between the light sources provided in a light module or between light sources of adjacent light modules can be compensated and are not perceived by the user when the light is emitted. The vapor guide plate is preferably made of glass. However, the vapor guide plate can also consist of Plexiglas, plastic or another light-conducting material.

According to one embodiment, the lighting device is arranged in the fume hood housing on a shoulder of a wall. A shoulder is understood to mean, in particular, a shoulder that protrudes into the interior of the extractor hood. By arranging the lighting device on such a step, the lighting device can be arranged at a distance from the suction opening in the extractor housing which corresponds to the height of the vapor deflector plate which protrudes into the extractor housing. The vapor baffle plate can, for example, rest on the lighting device.

According to one embodiment, the fume extraction device has a suction opening, through which air is sucked in downwards and the at least one vapor baffle plate is arranged adjacent to the suction opening. In this embodiment, the invention can also be used as a table fan, Trough ventilators or downdraft ventilators are referred to. In this embodiment, the configuration according to the invention of the fume conducting plate as a light guide and the arrangement of the lighting device below the fume conducting plate can be used particularly well. The suction opening preferably has an elongate shape. In this embodiment, the vapor guide plate preferably extends along the suction opening in the width direction. In particular, the vapor deflection plate extends in the width direction of the hob in an extractor device that is mounted behind a hob. The lighting device thus also extends in the width direction of the intake opening of the vapor extraction device and is arranged in a plane that lies below the intake opening.

In 1 a perspective view of an embodiment of the extractor device 1 according to the invention is shown. The extractor device 1 is arranged in a worktop 6 behind a hob 5 . The extractor device 1 has an extractor housing 2, from which 1 only the top is visible. A suction opening 20 is provided in the upper side of the fume hood housing 2 . Vapors and vapors that arise when cooking on the hob 5 can be sucked into the extractor device 1 via this suction opening 20 . For this purpose, the fume extraction device 1 has a fan, which is not shown in the figures.

in the in 1 The embodiment shown has the extractor device 1 on two steam baffle plates 3 . In particular, a vapor guide plate 3 is provided in front of the suction opening 20, that is to say between the suction opening 20 and the hob 5, and behind the suction opening 20. The vapor guide plates 3 are vertical and represent flat plates, in particular glass plates. The front vapor guide plate 3 has a smaller width and a lower height than the rear vapor guide plate 3. The vapor guide plates 3 extend in the width direction of the hob 5.

How out 2 results, the Wrasenleitplatte 3 extends over the suction opening 20 up and down. A lighting device 4 (see FIG 3 ) arranged below the vapor guide plate 3, via which light can be introduced into the vapor guide plates 3.

In 3 a part of the extractor housing 2 is shown. In particular, in the 3 a retaining plate 22 of the extractor housing 2 is shown. In the lower area of the holding plate 22 a shoulder 220 is introduced into the holding plate 22 . When the mounting plate 22 is installed in the extractor housing 2, the shoulder 220 extends into the interior of the extractor housing 2. The lighting device 4 represents a light bar. The lighting device 4 is placed in the shoulder 220 in the embodiment shown. In this embodiment, the top of the lighting device 4 is flush with the top of the step 220 . In the 3 only the cover part 401 of the housing 40 of the lighting device 4 is visible. Openings 4010 are made in the cover part 401, through which the light from the light modules of the lighting device 4 can pass.

In 6 an embodiment of a lighting device 4 is shown. The lighting device 4 represents a light bar and has a housing 40. The housing 40 consists of a cover part 401 and a holding part 402. The cover part 401 is arranged on the holding part 402. FIG. Light modules 43 are arranged between the cover part 401 and the holding part 402 . How out 7 results, the light modules 43 are arranged in a row or chain. The light modules 43 are connected to one another via connection elements 435 . Openings 4010 are provided in the cover part 401 . The light modules 43 are arranged in the housing 40 such that the light modules 43 are aligned with the openings 4010 . As a result, light that is output by the light modules 43 can exit through the openings 4010 and be introduced into the fume conducting plate 3 arranged above the lighting device 4 .

In the 8th and 9 an embodiment of a light module 43 for the lighting device 4 is shown. The lighting device 4 has a module housing 432 . The module housing 432 consists of an upper part 433 and a lower part 434 which are detachably connected to one another. In the embodiment shown, a circuit board 431 is accommodated in the module housing 432, on which two light sources 430 are arranged.

In 4 the extractor device 1 is shown in the area of the lighting device 4 . As can be seen from this view, the vapor guide plate 3 is arranged in such a way that its lower edge 30 rests on the lighting device 4 or is at least in the vicinity of the upper side of the lighting device 4 . In the 4 the filter element 23, which is provided in the extractor housing 2, can also be seen.

As emerges from the 5 results, the cover part 401 of the lighting device 4 is a bent metal sheet or a bent plastic part. In this embodiment, the openings 4010 extend over the fold of the curved cover part 401.

With the present invention, a compact, inexpensive and length-flexible lighting device, which can also be referred to as a light unit, that can be removed from the extractor device is created. The introduction of light into a vapor guide plate, which can also be referred to as a passive light guide, is made possible by the lighting device. The passive light guide is preferably the vapor trap plate of a downdraft system.

The appearance of different designs of the lighting device is the same for the user across all variants that can be displayed.

With the present invention, the extractor device with the lighting device can be implemented using a modular system that is kept as small as possible.

In this case, the edges of the vapor deflection plate facing away from the lighting device, in particular the glass edges, can illuminate decoratively and homogeneously.

The light source(s) are not visible and also do not have to be mechanically and electrically connected to the vapor guide plate that serves as a light guide.

The light is preferably introduced by individual light modules that are used n times.

It is sufficient to choose the distance between the individual light modules so large that the individual short light modules are not perceived as such on the opposite side of the vapor guide plate to the side where the light is introduced. A roughened edge design of the vapor guide plate also covers the individual light sources and illuminates homogeneously through the diffuse light scattering.

According to the invention, however, it is also possible to use a linear light as the lighting device. Such a lighting device must be individually adjusted in the case of different widths of the extractor device and in particular the suction opening.

The electrical connection of the light modules can be connected to one another via plug connectors or similar connections. In interaction with the holding and cover parts, which can preferably be made of sheet metal or plastic, the light module can form a geometry that is easy to clean.

Furthermore, it is conceivable that the lighting device has an additional scratch-resistant element and/or a sealing element against the ingress of dirt and moisture. This can be arranged over the cover part.

The lighting device is mechanically and electrically decoupled from the vapor guide plate, which is designed as a passive light guide. The steam baffle can be removed by lifting its own weight.

If service is required, the extractor hood can remain in the worktop; only the lighting unit has to be removed as an assembly.

The modular solution ensures that different widths of the extractor hood can only be implemented by adjusting the grid dimensions or changing the number of light modules. According to the invention, only parts that are easy to create or change are affected within the kit, the light module itself always remains the same.

The possible use of scratch-resistant materials and seals significantly increases the longevity of the extractor hood.
