  • the embodiments essentially correspond to that in FIG Figure 4 shown embodiment of the extractor hood 1. It will therefore only be described the features in which the embodiments according to Figures 9 to 11 of the embodiment according to Figure 4 distinguish.
  • At least one lighting element 2140 is arranged in such a way that it can emit light from the base body to the outside in the plane of the base body and thus couple it into the base plate 20.
  • the light L emerges from the edge of the base plate 20. In particular with a polished edge of the base plate 20, the light emerges in the horizontal and thus illuminates the interior of the viewing hood 14.
  • the embodiment according to Figure 10 differs from the embodiment according to Figure 9 in that the outer edge of the base plate 20 is provided with a facet. In this embodiment or in the case of a rougher edge, the outer contour of the base plate 20 is emphasized and the coupled-in light is output at least partially downwards.
  • the embodiment according to Figure 11 differs from the embodiment according to Figure 9 in that the base plate 20 forms a plate which is bent downwards at least in the edge region.
  • the base plate 20 can also have a satin finish on its top. As a result, the light L coupled in by the lighting elements 2140 is scattered flat at the bending radius and is visible to the user of the extractor hood 1.
  • an inner lighting unit 215 is provided instead of the outer lighting unit 214.
  • the lighting elements 2150 of the lighting unit 215 emit light in the plane of the base body 210 inwards.
  • a Light guide plate 216 added, through which light is coupled out downwards.
  • an external lighting unit (not shown) can additionally be provided.
  • the inwardly radiating lighting elements 2150 or parts of the lighting unit 215 can also be controlled independently of one another. In this way, the area illuminated in the base body 210, in which the light guide plate 216 is arranged, is divided into several zones.
  • a reflection unit 217 received in the base body 210.
  • the reflection unit 217 is shown schematically. Eight segments are formed in this. These are formed by partition walls in the reflection unit 217.
  • the lighting elements 2150 of the inner lighting unit 215 emit light into the different segments.
  • the segments are designed as triangular segments.
  • An outer cover 211 which forms a frame is provided at the bottom on the base body 210. The light is deflected downwards by the reflection unit 217.
  • the reflection unit 217 By means of the reflection unit 217, the individual segments can be delimited from one another better than when only one light guide plate 216 is used.
  • the geometry of the reflection unit 217 is designed in such a way that the lighting elements 2150 shine evenly over the entire luminous area.
  • the lighting elements 2150 or 2140 can be switched independently of one another, colored accents and light effects can be displayed.
  • segments depending on user functions such as ventilation level and overrun or to display device properties such as filter saturation.
  • FIG. 17 to 19 further embodiments of the lighting module 21 are shown.
  • an outer cover 211 is shown, in which openings 2110 are made, through which light, for example from a light guide plate 216 or another light guide element, such as the reflection unit 217, is passed on by the lighting elements 2150, can exit downwards
  • openings 2110 are arranged in such a way that they represent slots arranged in a circle. Individual slits lie under the different segments that are generated by separate control of the lighting elements 2140 and / or by the reflection unit 217. Thus, when the segment in which, for example, four slots are located, a high fan level of the fan of the extractor hood 1 can be displayed.
  • a glass cover 212 is attached to the underside of the base body 210 of the lighting module 21.
  • the glass cover 212 is light-tight in the basic state.
  • a passage area 2120 is provided in which it is transparent.
  • the glass cover 212 can be back-printed both in black opaque and in some cases in black translucent. The opaque area is cut out in the middle and backprinted in a ring shape in black translucent. If several segments of the lighting module 21 are now illuminated as described above by separate control of the lighting elements 2150 and / or the reflection unit 217, the annular passage area 2120 can be completely or partially illuminated and thus serve as a display, for example the fan level. In Figure 18 the annular passage area 2120 is illuminated, while in the Figure 19 only a few segments are illuminated and therefore only part of the annular passage area 2120 is illuminated.
  • a ring made of chrome / stainless steel (not shown), which has a smaller width than the annular passage area 2120, can in turn be attached to the underside of the glass cover 212.
  • the chrome ring can be surrounded with accent rings through the printed glass cover 212 in the operating state.
  • the present invention can be used in particular with extractor hoods in which the filter level is covered with an additional level, that is to say an air guide unit, which is for example a baffle plate. Often these levels are made of glass. This creates a graceful look. Due to its visual value, the level faces the user. The air is sucked in through a gap between the level and the edge of the device, especially the edge of the viewing hood. One speaks of an edge suction. In the case of so-called vertical food, this level only points towards the user and not towards the hob. In the case of angled dining and ceiling ventilation, the level faces both the user and the hob.
  • an air guide unit which is for example a baffle plate.
  • the present invention has a number of advantages. On the one hand, the freedom of design is increased, as many different lighting designs can be implemented and combined with the lighting module. Apart from the lighting module, only design parts without major technical functions have to be adapted to the desired effect. A preferably provided interface on the base body of the lighting module for design parts also allows front design on several levels.
  • the lighting module is also customer-friendly, as it preferably has surfaces that are easy to clean.
  • the robustness and service life of the lighting units are increased.
  • the lighting units can be protected from the air flow and thus from moisture and grease in a simple manner by a cover and a lower cover or a glass cover.
  • the lighting module represents its own, self-contained unit and can be added as a module to an existing extractor hood. An intervention in the overall conception is necessary if only to an extremely small extent.
  • the impairment of the air flow inside the extractor hood can also be minimized by a suitable shape of the cover of the lighting module.
