Definitions

  • the invention relates to a cooktop with an extractor device and a cooktop surface for placing pots and pans, the extractor device comprising an air inlet opening arranged in a recess in the cooktop surface, a fan for sucking in air through the air inlet opening and a grease filter.
  • a classic extractor hood is located above the hob. The vapor that rises due to its heat can be extracted very well.
  • a disadvantage of this solution is the tight space available for the grease filter below the hob surface and the associated difficulty in making it removable for cleaning.
  • dirt and liquids fall through the air inlet opening into the extractor hood.
  • a dirt collecting device must therefore be provided which can be removed for emptying.
  • the object is to provide a cooktop whose extractor device ensures improved neutralization of the air.
  • the hob surface is the surface on which pans and pots can be placed for cooking.
  • the hob surface can comprise several zones, usually four zones in private households.
  • downstream defines a sequence of arrangement of components within the air flow or within the air flow duct of the vapor extraction device. If the odor filter is arranged downstream of the grease filter, this means that the air entering the extractor device first flows through the grease filter and only afterwards through the odor filter.
  • the extractor device is primarily a circulating air extractor, which blows the sucked-in air back into the kitchen after filtering.
  • the vapor extraction device can also transport the sucked-in air to the outside.
  • the arrangement of an odor filter in the vapor extraction device has the advantage that bad odors are removed from the sucked-in air and the air can be blown back into the kitchen without any odors.
  • the odor filter has a first air inlet surface and a second air inlet surface, which are arranged at an angle greater than 2°, in particular greater than 5°, in particular greater than 10°, relative to one another.
  • the air inlet surfaces are designed to be flat and in particular the odor filter only includes exactly these two air inlet surfaces, namely the first air inlet surface and the second air inlet surface, and thus no further air inlet surfaces.
  • the number of air inlet surfaces is not limited with this definition.
  • the first and second air entry surfaces can be two of a plurality of air entry surfaces.
  • the arrangement of two air entry surfaces at a specific positive angle to one another means that not all of the air entry surfaces of the odor filter lie in a single plane.
  • the Odor filter a kink, so that the first air inlet surface is at an angle to the second air inlet surface.
  • a bent or kinked odor filter has the advantage that, due to its geometry, it can also be removed from the vapor extraction device through a narrow air inlet opening. The air inlet opening shouldn't be too big, because it reduces the usable area of the hob surface.
  • the odor filter comprises a first air outlet surface and a second air outlet surface, the first air outlet surface being arranged parallel to the first air inlet surface and the second air outlet surface being arranged parallel to the second air inlet surface.
  • the first and/or the second air inlet surface is/are preferably arranged at an angle of at most 45°, in particular at most 30°, in particular at most 15°, to the hob surface.
  • the hob surface is the surface on which the pans and pots are placed for cooking.
  • the first and/or the second air inlet surface are arranged horizontally.
  • the odor filter is arranged as horizontally as possible below the hob surface. In the horizontal extension, an area the size of the hob surface is available.
  • the odor filter can be dimensioned correspondingly generously. The larger the filter surface can be designed, the smaller the air resistance in the flow channel.
  • a part, in particular more than half, of the entire air outlet surface of the grease filter, in particular the entire air outlet surface of the grease filter, is advantageously at an angle of no more than 45°, in particular no more than 30°, in particular no more than 15° Arranged vertically to the hob surface. These angular intervals also include an angle of 0°.
  • the fat filter should not be arranged horizontally like the odor filter, but vertically. With a vertical arrangement of the grease filter, the air flows through horizontally and is then deflected in order to flow in a vertical direction through the horizontally arranged odor filter.
  • the vertical arrangement of the grease filter allows it to be as compact as possible, very close behind the air intake opening. Combined with the horizontal arrangement of the odor filter, this allows a space-saving arrangement of both components and easy removal through the air inlet opening for cleaning.
  • the entire air outlet surface, in particular part or more than half of the entire air outlet surface, of the grease filter is arranged at an angle of at least 45°, in particular at least 60°, to the first and/or second air inlet surface of the odor filter.
  • grease filters and odor filters are at a positive angle to each other.
  • the odor filter and the fan are advantageously arranged on opposite sides of the grease filter. That is, the odor filter is on a first side of the grease filter and the fan is on a second side of the grease filter, the first side and the second side being opposite with respect to the grease filter.
  • This arrangement has the advantage that there is sufficient space available for the arrangement both for the fan and for the odor filter, and the odor filter can have a correspondingly large filter surface.
  • the odor filter is arranged to the side of the grease filter and/or between the grease filter and the edge of the hob.
  • the term “lateral” is in reference to a common arrangement of the to understand the hob. "On the side” therefore means that the odor filter is not arranged below the grease filter, but to the side.
  • the air between the odor filter and the fan advantageously flows horizontally below the grease filter. This allows the fan and the odor filter to be located on different sides of the grease filter.
  • the odor filter is arranged in an air duct section which is designed in such a way that the air in this section experiences a flow direction reversal.
  • a flow direction reversal is understood to mean a change in direction of more than 90°, in particular more than 120°, in particular more than 150°.
  • the odor filter is an activated carbon filter and/or it has a fixed shape and/or a handle.
  • a "fixed shape” means that the odor filter cannot be folded or rolled up. It is fixed in its form and this cannot be changed.
  • both the grease filter and the odor filter can be removed for cleaning through the recess in the hob surface. A separate opening for servicing one of these components is therefore not required.
  • the grease filter and the odor filter are arranged and designed in such a way that the odor filter can only be removed if the grease filter has already been removed through the recess, and the odor filter can be removed immediately after the grease filter has been removed. This means that once the grease filter has been removed, no further component needs to be removed in order for the odor filter to be accessible and removable.
  • the 1 shows a hob with a hob surface 1 for placing pots 2 and pans.
  • the hob is shown in the usual installation position. The terms above, below, left, right are as in 1 shown to understand.
  • the hob surface 1 is arranged horizontally.
  • a hob rim 3 is present on the outside of the hob surface. It delimits the hob surface 1 .
  • the hob has an air inlet opening 4 in the middle, which is arranged in a recess in the hob surface 1 .
  • the air inlet opening 4 forms the inlet to the vapor extraction device, which is arranged below the hob surface 1 .
  • the vapor extraction device also includes an air duct 5 , a grease filter 6 , an odor filter 7 and a fan 8 .
  • the fan 8 sucks in air through the air inlet opening 4 , which then flows through the air duct 5 .
  • the arrows shown represent the air flow through the air duct 5. After the air has entered through the air inlet opening 4, the air flows through the grease filter 6. The air then flows through the odor filter 7, which is arranged downstream of the grease filter 6. The air then flows horizontally below the grease filter 6 to the fan 8. After the fan 8, the air leaves the vapor extraction device.
  • the fat filters 6 are arranged approximately vertically.
  • the fat filters 6 are at an angle A of about 10° to the dashed line 11, which represents the vertical to the hob surface 1.
  • the line 12 shows an extension of the left-hand grease filter 6. Due to the vertical arrangement, the grease filter 6 can be easily removed through the air inlet opening 4. Together with the drip tray 13, the grease filter 6 forms a removable unit.
  • the air flows through the grease filter 6 and leaves it on the air outlet surface 61 arranged on the outside.
  • the air then flows to the left to the odor filter 7 , which is arranged to the side of the grease filter 6 .
  • the fan 8 and the odor filter 7 are arranged opposite one another in relation to the grease filter 6 .
  • the odor filter 7 is arranged between the grease filter 6 and the edge 3 of the hob.
  • the odor filter 7 can be an activated carbon filter. It has a first flat air inlet surface 71 and a second flat air inlet surface 72 . These are arranged at an angle B of approx. 10° to one another.
  • the odor filter 7 thus has a kink 73 which delimits the two air inlet surfaces 71, 72 from one another.
  • the first air inlet surface 71 is horizontal and thus arranged parallel to the hob surface 1 .
  • the second air inlet surface 72 is at an angle B of approx. 10° to the hob surface 1.
  • the odor filter 7 also has a first air outlet surface 74, which is arranged parallel to the first air inlet surface 71, and a second air outlet surface 75, which is parallel to the second air outlet surface 72 is arranged on.
  • the odor filter 7 is horizontal in the vapor extraction device.
  • An angle C of approximately 80° is formed between the air outlet surface 61 of the grease filter 6 and the first air inlet surface 71 .
  • the angle between the air outlet surface 61 of the grease filter 6 and the second air inlet surface 72 of the odor filter 6 is approximately 90°.
  • the arrangement inclined relative to one another means that the air flow in the air duct 5 undergoes a change in direction.
  • the odor filter 7 is arranged in the middle of this reversal of direction.
  • the 2 shows the removal of the odor filter 7 through the air inlet opening 4.
  • the removal of the odor filter 7 is possible because the grease filter 6 has already been removed through the air inlet opening 4. After removing the grease filter 6, the odor filter 7 can be removed immediately afterwards. No further components need to be removed.
  • the odor filter 7 has a fixed shape, i.e. it cannot be folded or rolled up, for example. It can be easily removed through the narrow air inlet opening 4 due to the bend 73. The user grips the odor filter 7 by the handle 76 and pulls it out through the air inlet opening 4 .
