Description

Technical Field

[0001] The invention relates to a range fumes extraction device with a smoke guide plate and a lighting device. Background Art

[0002] In so-called downdraft systems (which are installed in the worktop and in which the range hood housing projects upwards beyond the worktop on which the cooktop is mounted), it is known to arrange a light source at the upper end of the range hood housing. The cooktop is illuminated by the light source, which is installed, for example, at a height of generally between 20 and 40 cm.

[0003] A disadvantage of this type of lighting is that, on the one hand, the light source is directly visible to the user and, on the other hand, is exposed to steam and smoke rising from the stove. Summary of the Invention

[0004] It is therefore an object of the present invention to provide a range hood device with an illumination device which does not have the disadvantages of the prior art and which can nevertheless be easily assembled and operated.

[0005] According to the present invention, this object is achieved by a range hood device comprising a range hood housing, at least one smoke guide plate releasably held in the range hood housing, and at least one lighting device having at least one light source. The range hood device is characterized in that the smoke guide plate represents a light conductor, the lighting device is arranged below the smoke guide plate, the at least one light source faces the lower edge of the smoke guide plate, and the lighting device is releasably held on the range hood housing.

[0006] A range hood device is a device for purifying contaminated air, in particular steam and smoke, generated during cooking. The range hood device comprises a range hood housing. An intake opening is provided in the upper side of the range hood housing, through which air is drawn in. The smoke guide plate is preferably at least partially accommodated in the range hood housing. For this purpose, the range hood housing preferably has a guide for the smoke guide plate. In addition, the range hood housing has at least one retaining plate. The retaining plate can represent a side wall of the range hood housing or be fastened to the range hood housing, for example, a side wall of the range hood housing.

[0007] The range hood device has at least one smoke guide plate. A smoke guide plate is a planar element that guides the air sucked in by the blower inside the range hood device to the intake port of the range hood device. A plurality of smoke guide plates can also be provided on the range hood device. In particular, a smoke guide plate can be arranged in front of the intake port and a smoke guide plate can be arranged behind the intake port at the intake port, so as to form a conveying channel in front of the intake port in the direction of flow. According to the present invention, the smoke guide plate is releasably held in the range hood housing. The smoke guide plate can be guided in the range hood housing, for example, by vertical rails. In addition, the smoke guide plate can be held in the range hood housing from below.

[0008] According to the present invention, the at least one smoke guide plate represents a light guide. In particular, the smoke guide plate is made of a material suitable for light conduction. According to one embodiment, the smoke guide plate is made of glass, that is, it is formed by a glass plate. The surface of the glass plate can be polished, so that light introduced into the glass plate via one of the edges is reflected on the surface and thus further conducted.

[0009] A lighting device, which can also be referred to as a lighting means or a light strip, is a device by which light is emitted. According to the invention, the lighting means has at least one light source.

[0010] According to the present invention, the lighting device is arranged below the smoke guide plate. In particular, the lighting device is arranged below the lower edge of the smoke guide plate.

[0011] Directional specifications such as top, bottom, front, and rear, as well as specifications such as width and height, unless otherwise stated, relate to a range hood arrangement and its components in the installed state. In particular, these specifications relate to a range hood arrangement with at least one vertically arranged smoke guide plate, wherein the range hood arrangement is installed in a horizontal worktop behind the cooktop and extends behind the cooktop in the width direction of the cooktop.

[0012] The smoke guide plate is preferably held in the extractor housing in such a way that it stands on the lighting device or is positioned at a small distance relative to the lighting device.

[0013] The light source is directed toward the lower edge of the smoke guide plate. This means that light from the light source can be introduced into the smoke guide plate through the lower edge of the smoke guide plate.

[0014] According to the present invention, the lighting device is detachably fixed on the range hood housing. In particular, the lighting device can be fixed on a retaining plate, a side wall or a bottom of the range hood housing.

[0015] The present invention thus provides a range hood device by means of which light can be guided from below the smoke guide plate into the upper region of the smoke guide plate via the smoke guide plate's design as a light conductor. Furthermore, the lighting device can be removed and, if necessary, repaired or at least replaced due to its releasable fastening to the range hood housing.

[0016] According to a preferred embodiment, the lighting device includes at least two light modules, each of which includes at least one light source. According to the present invention, a light module refers to a separate structural unit that can be installed as a unit in the lighting device. The light sources are preferably arranged in a row within the light modules. This allows the alignment of the light modules to create a row of light sources that can direct light into the edges of the smoke deflector plate. The arrangement of at least two light sources in each light module simplifies assembly of the lighting device, as each light source does not need to be individually integrated.

[0017] According to a preferred embodiment, the at least two light modules are releasably connected to one another. In particular, the light modules can be connected to one another via connecting elements, such as plugs. The light modules are arranged one after the other in a series. The releasable connection of the light modules allows individual light modules to be replaced if one becomes defective without having to replace the entire lighting device.

[0018] Preferably, the lighting device comprises a housing, which is composed of a retaining member and a cover member that are detachably connected to each other, and in which the at least one light module is accommodated.

[0019] At least one opening for light transmission is preferably provided in the cover. In the assembled state of the lighting device, at least one light module is located in the housing below one of the openings. The light module can at least partially pass through the opening. However, the top side of the light module preferably terminates flush with the cover in the region of the opening.

[0020] According to one embodiment, the light module includes a module housing composed of a transparent upper part and a lower part, wherein the light source in the light module faces the upper part. The upper side of the module housing is defined as the side facing the smoke deflector plate in the installed state. The upper and lower parts of the module housing are preferably releasably connected to each other.

[0021] According to one embodiment, the edge of the smoke guide plate facing the lighting device has a roughened surface. The edge facing the lighting device represents, in particular, the lower edge of the smoke guide plate. This edge has a roughened surface, so that light can enter the smoke guide plate in a diffuse manner and the light output by the smoke guide plate can be made uniform. In particular, the distances between light sources arranged in a light module or the distances between light sources of adjacent light modules can be compensated and not be noticed by the user during the light output. The smoke guide plate is preferably made of glass. However, it can also be made of Plexiglas, plastic or other light-conducting materials.

[0022] According to one embodiment, the lighting device is arranged on a shoulder of a wall in the range hood housing. A shoulder is particularly a shoulder that projects into the interior of the range hood housing. The lighting device is arranged on such a shoulder so that it can be positioned in the range hood housing at a distance from the intake opening that corresponds to the height of a smoke guide plate extending into the range hood housing. The smoke guide plate can, for example, rest on the lighting device.

[0023] According to one embodiment, the range hood extraction device has an intake opening through which air is drawn downward, and the at least one smoke guide plate is arranged adjacent to the intake opening. In this embodiment, the present invention can also be referred to as a tabletop ventilation device, a recessed ventilation device, or a bottom exhaust ventilation device. In this embodiment, the design of the smoke guide plate as a light conductor according to the invention and the arrangement of the lighting device below the smoke guide plate can be particularly well utilized. The intake opening preferably has an elongated shape. In this embodiment, the smoke guide plate preferably extends along the width of the intake opening. In particular, in a range hood extraction device installed behind a cooktop, the smoke guide plate extends along the width of the cooktop. The lighting device thus also extends along the width of the intake opening of the range hood extraction device and is arranged in a plane below the intake opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] exist Figure 1 A perspective view of an embodiment of the range hood device 1 according to the present invention is shown in FIG. The range hood device 1 is arranged behind the cooktop 5 in the worktop 6. The range hood device 1 comprises a range hood housing 2 in which a Figure 1 Only the top side can be seen. An intake port 20 is provided in the top side of the range hood housing 2. Steam and smoke generated during cooking on the cooktop 5 can be drawn into the range hood device 1 through this intake port 20. For this purpose, the range hood device 1 has a blower (not shown in the drawing).

[0035] exist Figure 1In the illustrated embodiment, the range hood device 1 has two smoke guide plates 3. In particular, a smoke guide plate 3 is provided in front of the intake opening 20, that is, between the intake opening 30 and the cooktop 5, and behind the intake opening 20. The smoke guide plates 3 are positioned in a vertical line and represent flat plates, in particular glass plates. The front smoke guide plate 3 has a smaller width and height than the rear smoke guide plate 3. The smoke guide plates 3 extend along the width of the cooktop 5.

[0036] As Figure 2 As shown, the smoke guide plate 3 extends upward and downward through the intake opening 20. Below the intake opening 20, a lighting device 4 (see FIG. Figure 3 ) is arranged below the smoke guide plate 3 and can be used to guide light into the smoke guide plate 3.

[0037] exist Figure 3 FIG shows a portion of the range hood housing 2. Figure 3 , the holding plate 22 of the range hood housing 2 is shown. In the region below the holding plate 22, a shoulder 220 is incorporated into the holding plate 22. When the holding plate 22 is installed in the range hood housing 2, the shoulder 220 extends into the interior of the range hood housing 2. The lighting device 4 represents a light strip. In the embodiment shown, the lighting device 4 is incorporated into the shoulder 22. In this embodiment, the upper side of the lighting device 4 ends flush with the upper side of the shoulder 220. Figure 3 In the figure, only the cover 401 of the housing 40 of the illuminating device 4 can be seen. An opening 4010 is formed in the cover 401, and light from the light module of the illuminating device 4 can pass through the opening.

[0038] exist Figure 6 FIG. 4 shows an embodiment of a lighting device 4. The lighting device 4 represents a light strip and has a housing 40. The housing 40 is composed of a cover 401 and a holder 402. The cover 401 is arranged on the holder 402. A light module 43 is arranged between the cover 401 and the holder 402. Figure 7 As shown, the light modules 43 are arranged in a row or chain. The light modules 43 are connected to each other via connecting elements 435. An opening 4010 is provided in the cover 401. The light modules 43 are arranged in the housing 40 so that they are aligned with the opening 4010. As a result, light output by the light modules 43 can be emitted through the opening 4010 and directed into the smoke deflector plate 3 arranged above the lighting device 4.

[0039] exist Figure 8 and 9 shows an embodiment of a light module 43 for the lighting device 4. The lighting device 4 has a module housing 432. The module housing 432 is composed of an upper part 433 and a lower part 434 that are releasably connected to each other. In the illustrated embodiment, a circuit board 431 is accommodated in the module housing 432, on which two light sources 430 are arranged.

[0040] exist Figure 4 shows the exhaust device 1 in the area of ​​the lighting device 4. As this view shows, the smoke guide plate 3 is arranged so 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. Figure 4 The filter element 23 arranged in the extractor housing 2 can also be seen.

[0041] As Figure 5 As shown, the cover 401 of the illuminating device 4 is a bent metal sheet or a bent plastic part. In this embodiment, the opening 4010 extends through the bent edge of the bent cover 401.

[0042] The present invention provides a compact, cost-effective, and flexible-length lighting device that can be removed from the range hood. This lighting device, which can also be referred to as a light unit, is used to introduce light into a fume guide plate, which can also be referred to as a passive light conductor. The passive light conductor is preferably a fume collecting plate in a downdraft system.

[0043] The appearance of the different designs of the lighting device is identical to the user within the scope of all depicted variants.

[0044] With the present invention, the range hood device with the lighting device can be realized by means of standard components that are kept as small as possible.

[0045] In this case, the edge of the smoke guiding plate facing away from the lighting device, in particular the glass edge, can be illuminated decoratively and uniformly.

[0046] The light source is not visible and furthermore does not have to be connected mechanically and electrically to the smoke deflector plate serving as a light conductor.

[0047] The light introduction is preferably carried out via the individual n-fold used light modules.

[0048] It is sufficient to select the spacing between the individual light modules to be large enough so that the short light modules themselves are not noticeable on the side of the smoke guide plate opposite the light intake side. The roughened edge shape of the smoke guide plate additionally conceals the individual light sources and, due to diffuse light scattering, produces a uniform illumination.

[0049] However, according to the invention, it is also possible to use linear lamps as lighting devices. In the case of different widths of the range hood devices and in particular the intake openings, such lighting devices must be individually adjusted.

[0050] The electrical connections of the light modules can be connected to one another via plug connectors or similarly arranged connections. The light modules can be formed into a cleaning-friendly geometry in interaction with the holder and cover, which can preferably be made of sheet metal or plastic.

[0051] Furthermore, it is conceivable that the lighting device comprises an additional scratch-resistant element and / or a sealing element in order to prevent the ingress of dirt and moisture. The scratch-resistant element or the sealing element can be arranged on the upper side of the cover.

[0052] The lighting device is mechanically and electrically decoupled from the smoke guide plate, which is designed as a passive optical waveguide. The smoke guide plate can be removed by lifting it under its own weight.

[0053] The extractor hood can remain in the work panel during maintenance; only the lighting device must be removed as a subassembly.

[0054] This modular solution ensures that different widths of the range hood can be achieved simply by adjusting the size of the grilles of the light module or changing their number. Within the modular component, the invention only involves components that can be easily manufactured or modified; the light module itself always remains identical.

[0055] The possible use of scratch-resistant materials and seals further significantly increases the service life of the range hood arrangement.
