Definitions

  • the present invention relates to an extractor hood with means for generating at least two light cones, as well as a kitchen section with an extractor hood.
  • the extractor hoods have a lighting unit that illuminates a hob arranged under the extractor hood.
  • a lighting unit that illuminates a hob arranged under the extractor hood.
  • Such an extractor hood is for example in US 2015/184869 A1 disclosed.
  • Usual hobs consist of a glass or a glass ceramic. It is particularly preferred to use hobs which are made of black material or at least partially have a black coating.
  • the disadvantage of the known designs of the lighting unit of the extractor hood in the prior art is that due to the nature of conventional hobs, a not inconsiderable part of the light is absorbed by the often dark hob and another, not inconsiderable part of the light is reflected by reflective properties of the hob . The light is usually reflected upwards past the viewer due to the spatial restrictions imposed by the design of the extractor hoods. Both of these effects make the lighting appear dark to a viewer. Even if the reflected light were to hit the viewer, it would be disadvantageous because reflected light can dazzle the viewer.
  • Another problem with this design is that cookware that is on the hob is brightly illuminated by this lighting, however, the wall behind it is not irradiated, which can lead to an unfavorable contrast between the cookware and the background for a viewer.
  • the object is achieved by an extractor hood with means for generating at least two light cones with the features of claim 1.
  • the object is also achieved by a kitchen section with an extractor hood according to claim 16.

  • the y-axis point to the front, the z-axis to the top and the x-axis to the side.
  • the x-direction and the y-direction therefore designate directions in the horizontal and the z-axis the direction in the vertical.
  • the y-direction is the direction from the back to the front and the x-direction is the direction from one side surface to the opposite side surface.
  • an extractor hood which comprises a rear side and two side surfaces and means for generating at least two light cones, at least one first light cone being emitted in a direction which is downward onto the surface of the vertical projection of the extractor hood is directed, characterized in that the means for generating at least two light cones are adapted so that at least one second light cone is emitted in a direction whose horizontal component is to the plane in which the rear of the extractor hood is, or to at least one plane , in which one of the two side surfaces of the extractor hood lies, shows.
  • the extractor hood preferably has an extractor housing in which the fan of the extractor hood is provided and in which the extraction opening of the extractor hood can be formed.
  • the suction opening can be provided on the underside of the extractor hood or on the front.
  • the extractor hood can have a viewing hood in which the extraction opening is located.
  • the extractor hood has a rear and two side surfaces.
  • the rear side which is also referred to as the rear side, is the side that is mounted on a mounting wall, in particular a room wall of a kitchen. The side surfaces extend forward from the rear wall.
  • the viewing hood can be provided, for example, on the underside of the extractor housing.
  • the side of the extractor housing that rests against the mounting wall or the side of the viewing hood that rests against the wall is therefore referred to as the rear.

  • the means for generating the at least one light cone particularly preferably comprise at least one lighting unit.
  • the means are therefore also referred to below as a lighting unit.
  • At least a first and a second light cone are generated.
  • the designations first and second are only used for better reference to the light cones and do not represent a time designation.
  • the at least one first cone of light is emitted in a direction which is directed downward onto the surface of the vertical projection of the extractor hood.
  • a hob is usually arranged in the area of the vertical projection or at least in the plane of the area of the vertical projection of the extractor hood downwards.

  • This embodiment is different from the embodiment Figure 6 also in that the second cone of light (150) has a wide opening angle and therefore parts of the hob (220) are illuminated by the second cone of light (150) and also not insignificantly overlap with the first cone of light (140).
  • the first cone of light (140) in this embodiment has a higher luminous flux than the second cone of light, so that the hob (220) is brightly illuminated.
  • the extractor hood (100) has two lighting units (130), the lighting unit (130) arranged further to the front generating a first and a third light cone (140), both of which are directed onto different parts of the hob (220).
  • the lighting unit (130) arranged further back generates the second light cone (150), which is directed onto the kitchen rear wall (210), ie the direction vector (156) points to the kitchen rear wall (210).
  • the second light cone (150) in this embodiment also illuminates part of the plane (222) of the worktop.
  • Generating the cones of light by a plurality of lighting units (130) can also be advantageous, since a greater variety of lighting geometries can be generated in this way and, if necessary, simpler optics can be used.
  • FIG 9 a further embodiment of the extractor hood (100) according to the invention and the kitchen section (200) according to the invention is shown schematically.
  • the kitchen section has a kitchen side wall (230) instead of a kitchen rear wall, which is illuminated by the second light cone (150).
  • the lighting device (130) emits the second light cone (150) in -z / -x - direction so that the direction vector (156) of the second light cone (150) points to a plane (122) in which one of the side walls (120 ) the extractor hood (100) is located.
  • the cone of light (150) hits this plane (122) within a vertical distance from the hob (220) provided for the extractor hood (100).
  • the direction vector (156) points to the kitchen side wall (230). This also results in favorable lighting for a kitchen geometry in which the extractor hood (100) is arranged next to a kitchen side wall (230).
