Definitions

  • the invention relates to an extractor hood, in which the suction of the vapors and Vapors are related to the hotplate.
  • an extractor hood which has means for a Sliding and / or rotating movement for the purpose of movable attachment.
  • Slide rails, rollers and hinges are used. That’s it it is possible to close the extractor hood above and over the hotplates move to an intense one over the hotplates in use To aspirate the vapors and vapors. There is also a fold up on the Wall possible.
  • an extractor hood is known from DE 41 42 474 A1, the divided one Extraction parts with horizontally arranged filters for extracting the vapors and vapors on the one hand for the front hotplates and on the other hand for the rear hotplates of the Cooker has.
  • An extractor hood with at least three parts is used, two Parts of the separate air duct and the third part serve the fume cupboard Suction fans represents.
  • the suction parts can be operated separately or together. With separate Extraction, each suction fan is driven by its own motor, otherwise one motor is sufficient for the two suction fans.
  • this extractor hood is made of three parts is composed, with at least the two suction parts in itself must be designed to prevent the suction of fumes and To prevent vapors. That makes the extractor hood difficult.
  • an extractor hood is on the cooking area side arranged in front of the filter of the extractor hood, the suction opening points towards the hob.
  • the extractor hood can be moved in the horizontal filter level or displaceable and pivotable downwards relative to the filter level and changeable in altitude. Extracting the vapors and vapors through the hood is done by the fan system of the extractor hood via a hose or the extractor hood has its own additional filter and fan system.
  • the Disadvantages of this solution are the cost of the additional filter and Fan system and secondly in the use of the hose for suction. This is dirty light and will therefore find little acceptance in the household.
  • the extractor device according to DE 199 07 057 A1 is in the kitchen worktop arranged sunk. It is extended to the suction mode and to Food carrier swung in. Their disadvantage is at least that the open space of the Kitchen worktop is restricted.
  • the object of the invention is to extract the fumes from the cooking point To improve vapors. This object is achieved 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 separate suction shaft and each partial filter surface is a fan suction nozzle or assigned a fan blower, the speed of the fan blower independent should be controllable from each other.
  • the suction funnel with the control for the speed of the fan blower coupled, the partial filter surface where the suction funnel is located can be optimal be sucked off.
  • the design of the suction funnel is also of major 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 outer surface.
  • the Suction funnels inside have air baffles on the outer surface, which are preferred are arranged spirally.
  • the material of the suction funnel is also important for its effectiveness.
  • the invention therefore provides that the suction funnel is preferably made of metal or externally insulated metal or externally heated metal or externally heated Metal is made with an insulating layer above.
  • the invention provides that the suction funnel in the Suction funnel height is adjustable. This can be easily achieved by the casing of the suction funnel is composed like an iris or out section overlapping truncated cone sections.
  • the suction funnel arrangement according to the invention offers the possibility of that the suction funnel is equipped with a prefilter, preferably one with a small flow resistance, and / or in the area of the suction opening of the Suction funnel to arrange a circumferential condensate / grease trap inside.
  • the extractor hood 1 shown in Fig. 1 consists of the housing 2 with the inside arranged filter frame 4 with filter 3. Below the filter 3 is the suction funnel 5 arranged with a clear distance A to the filter 3. The suction funnel 5 is on one pivoted pivot lever 10 out, which is arranged centrally in the frame of the filter 3 is. By simply swiveling the filter, the partial filter surfaces 3.1 - 3.4 be assigned.
  • the extractor hood 1 is made of four sheets Duct spaces divided, and each partial filter area 3.1 - 3.4 is a fan suction nozzle 9 assigned. It is also possible for each of these subspaces to have its own fan blower 8 assigned. The speed of the fan blowers 8 can be controlled independently of one another.
  • the suction funnel 5 is coupled to the control for the speed of the fan blower 8, such that the partial filter surfaces 3.1 - 3.4 correspond to the position of the suction funnel 5, which is located in the illustration at the partial filter area 3.1, optimally suctioned off become.
  • the extractor hood 1 has in the area below the filter 3 on the hob side of the filter frame 4 lying opposite to one another parallel to its outer edges Guide rails 13 on.
  • the guide rails are by at least one Cross rail 14 connected to each other, the cross rail 14 along the guide rails 13 is displaceable and the suction funnel 5 along the cross rail 14.
  • the distance A is dimensioned such that the suction fan (s) 8 generate a suction effect in the suction funnel 5 in the extractor hood 1.
  • the trumpet shape shown in Fig. 2 for the suction funnel 5 supports the Chimney effect. It prevents swirling of the boundary layer, which means little saturated air sweeps past the funnel surface, which leads to less condensate.
  • the suction funnel shown in Fig. 3 is perforated.
  • the openings in the direction of flow prevent condensate from being deposited by supplying unsaturated room air.
  • the asymmetrical suction funnel 5 shown in FIG. 4 enables an additional one Rotate 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 by good vacuum generation in the upper suction area.
  • the suction funnel 5 with air guiding orifices shown in FIG. 6 leads to stabilization of the fumes below the funnel.
  • the suction funnel 5 is preferably made of metal. This allows a quick adaptation to the steam temperature, which the Condensate failure reduced. Furthermore, the suction funnel 5 made of metal on the outside Have insulation 11, as shown in Fig. 7. The material in the boundary layer to Steam heats up even faster here, which further reduces the condensate failure. In addition, it is also possible to heat the suction funnel 5 or the heater 12 to isolate the outside additionally. This is shown in FIGS. 8 and 9.
  • Suction funnel 5 is adjustable in funnel height.
  • Such training, once composed of sections of truncated cone and once by an iris formation are shown in Figs. 10 and 11.
