Definitions

  • the invention relates to a cooker hood, in which the suction of the vapors and Vapors takes place by boiling point.
  • an extractor hood which has means for a Sliding and / or rotary movement has the purpose of a movable attachment. Sliding rails, rollers and hinges are used. That's it possible, the cooker hood over the hobs laterally and / or to from to to move over the hotplates in use an intensive Extracting the fumes and fumes to reach. Furthermore, a flip up at the Wall possible.
  • An at least three-part extractor hood is used, with two Parts of the separate air duct serve and the third part with the trigger block Suction blowers represents.
  • the suction can be separated and operated together. With separate Extraction, each aspirator is powered by its own motor, otherwise is sufficient for a motor for the two suction fan.
  • the extractor device according to DE 199 07 057 A1 is in the kitchen worktop sunk. It is extended upwards for intake operation and for Food support swung in. Their disadvantage consists at least in that the open space of the Kitchen worktop is restricted.
  • the object of the invention is the cooking point-related suction of the vapors and To improve vapors. This problem is solved with the features of claim 1, advantageous embodiments are the subject of the dependent claims.
  • the filter surface of the filter is in partial filter surfaces with own exhaust duct divided and each Operafilter Structure is a Ldorfgdüse or a fan blower associated with the speed of the fan blower independently should be controllable from each other.
  • the formation of the suction funnel has significant importance for the Effectiveness of the extractor hood according to the invention.
  • the suction funnel has a trumpet shape or is asymmetrical, or is a double funnel, or has a perforated lateral surface.
  • the Extraction funnels inside have air guide on the lateral surface, the preferred are arranged spirally.
  • the material of the suction funnel is important for its effectiveness.
  • the invention therefore provides that the suction funnel is preferably made of metal or of externally insulated metal or externally heated metal or externally heated Metal is made with an insulating layer located above.
  • the invention provides that the suction funnel in the Suction cup height is adjustable. This can be achieved in a simple way by the sheath of the suction funnel is like an iris or composed of itself sectionally superimposed truncated cone sections.
  • the suction funnel arrangement according to the invention offers the possibility that the suction funnel is equipped with a pre-filter, preferably one with a small flow resistance, and / or in the region of the intake opening of Intake funnel inside a circulating condensate / grease gutter to arrange.
  • the extractor hood 1 shown in Fig. 1 consists of the housing 2 with the therein arranged filter frame 4 with filter 3. Below the filter 3 is the suction funnel. 5 arranged with a clearance A to the filter 3. The suction funnel 5 is at a pivotable pivot lever 10 out, which is arranged centrally in the context of the filter 3 is. By simply tilting the filter can thus the sub-filter surfaces 3.1 - 3.4 be assigned.
  • each sub-filter surface 3.1 - 3.4 is a fan intake 9th assigned. It is also possible, each of these subspaces its own fan fan. 8 assigned.
  • the fan blower 8 are independently controllable in speed.
  • the suction funnel 5 is coupled to the speed control of the fan blower 8, such that the sub-filter surfaces 3.1 - 3.4 according to the position of the suction funnel 5, which is located in the representation at the sub-filter surface 3.1, optimally aspirated become.
  • the guide rails are through at least one Cross rail 14 connected to each other, wherein the cross rail 14 along the guide rails 13 is displaceable and the suction funnel 5 along the cross rail fourteenth
  • the trumpet shape shown in Fig. 2 for the suction funnel 5 supports the Chimney effect. It prevents turbulence of the boundary layer, which means little saturated air passes the funnel surface, resulting in less condensate.
  • the suction funnel shown in Fig. 3 is perforated.
  • the openings in the flow direction Prevent condensate deposits by supplying non-saturated room air.
  • the asymmetrical suction funnel 5 shown in FIG. 4 allows an additional Turn away from the work area or into the vapor area.
  • the suction funnel 5 in Fig. 5 consists of a double funnel and is characterized a good negative pressure generation in the upper suction.
  • the suction funnel 5 with air guide orifices shown in FIG. 6 leads to stabilization the Wrasens below the funnel.
  • the suction funnel 5 is preferably made of metal. As a result, a quick adaptation to the steam temperature is achieved Condensate failure reduced. Furthermore, the suction funnel 5 made of metal outside a Insulation 11, as shown in Fig. 7. The material in the boundary layer to the Steam heats up even faster, which further reduces condensate loss. In addition, it is also possible to heat the suction funnel 5 and the heater 12th isolate on the outside in addition. This is shown in FIGS. 8 and 9.
  • Suction funnel 5 is adjustable in the funnel height.
  • Such training once composed of sections overlapping truncated cone sections and once by an iris formation are shown in Figs. 10 and 11.
