Definitions

  • the present invention relates to an extractor hood for the extraction of Cooking fumes with a suction surface through which emanate from a hob Fumes pour.
  • Such extractor hoods are available in many different Embodiments known. They generally have one substantially horizontal suction surface through which the above the hob from this outgoing fumes in the hood flow in and after a filtration in a fat and / or odor filter discharged through an exhaust duct be returned to the room in recirculation mode.
  • a disadvantage of previously known extractor hoods is that of the Cooking field emanating fumes often not completely into the suction surface of the Extractor hood can be sucked in, but partly flow past it and thus not be cleaned or vacuumed, which is especially true is calculated when the onset of cooking fumes is particularly large.
  • slats are provided in the region of the suction surface, the one or more in at least one operating state of the hood limit between these arranged passage spaces, through the vapors enter the suction area.
  • the slats prevent the cooking fumes from Flow past the suction and cause them to a preferred direction obtained on the suction surface of the hood.
  • the slats in different positions movable and limit one or more of the passage spaces in at least one position, through which the fumes enter the suction surface. Due to the mobility of the Slats these can vary depending on the operating state of the hood Take positions.
  • the slats are in not switched on state of the hood in a plane, causing a uniform visual impression results.
  • the slats In the switched-on position the slats can be set at an angle to the suction surface, whereby these passage gaps release, through which the fumes into the extractor hood flow.
  • the slats thus be arranged fixed or movable.
  • the slats can be moved by means of a drive or manually between a position, in which they include an angle> 0 ° with the suction surface, and a position in which the lamella essentially in the plane of the suction or in lie on a parallel plane, be movable.
  • the suction surface may be inclined relative to the horizontal, but in principle also located in the horizontal.
  • the inclination is preferably such executed that the suction surface as well as the slats to the user of Extractor hood are directed. From an obliquely arranged extractor hood there is the advantage of sufficient headroom (ergonomics).
  • the slats can be moved, preferably pivotable in a frame or be arranged a housing. It can be provided that in the frame or housing grease and / or odor filter are arranged. Especially advantageous It is when the hood has a body and when the Frame or the housing is designed to pivot relative to the body.

  • Conceivable are rotary bolts, magnetic closures, Magnetic pressure locks, sliding closures or automatic Spring snap fasteners, also known as Touch Laces closures.
  • the frame or the housing is advantageous with guide or brake fittings Mistake.
  • gas damper or oil damper may be provided, which, for example can be linear or rotatable as a damper. Any Damper holders come into question.
  • the lamellae are preferably without tools from the Extractor hood are designed removable.
  • the slats can in their End portions in a bore preferably in a bore of the frame or Housing pivotally mounted.
  • the extractor hood comprises a lighting device. This can be above, below, laterally of the lamellae or in the flow direction of the fumes behind be arranged on the slats so that lighting is only possible if the blades are in an open, i. pivoted position. It can be provided that the lighting is turned on when the slats be moved into an open position or operating position, in between the slats passage column are located.
  • the lamellae are movable by motor and the Position of the slats depends on the operating state of the extractor hood.
  • the slats in the off state of Extractor hood essentially lie in one plane and switched on Condition of the hood against the plane of the trigger surface employed are. If the slats lie in one plane, they can form a closed surface form or leave column free.
  • the slats alternatively from Hand are designed to be movable.
  • the angle of attack and thus the size of the passage gap with increasing operating level of the hood increases. It can thus different opening positions of Slats for different operating levels of the hood or a be arranged therein fan provided.
  • At least one driven or manually is provided to actuate push rod, with the lamellae in such a way is that the movement of the push rod is an adjusting movement of the Slats causes.
  • the slats on the push rod by means of a Magnet be releasably attached.
  • Such a releasable attachment brings the advantage with it, that the lamella when hitting an obstacle (pinching a finger) from the push rod or any other drive unit triggers, after which no more force acts on the lamella and an effective clamp protection is realized.
  • the lamellae can be directly or indirectly at the Push rod releasably secured by a magnet. It can be provided be that the slats are connected to a steering lever, which is a magnet has, which is received in a guide of the push rod.
  • the guide for the magnet in one Long hole of the push rod is added.
  • the guide for the magnet is also magnetic executed. It consists for example of magnetic steel.
  • the slats can be pivotally mounted in their end regions.
  • the slats can also serve levers, on the one hand with the slats and on the other hand with a frame or housing or with the body of the hood pivotally communicate.
  • the lamellae are detachable with a drive device to be associated with these when encountering an obstacle of the drive unit to be solved.
  • a detachable connection For example, a magnetic connection.
  • a switch is provided in whose On-position the hood is turned on and the adjustment of the Slats in a position in which arranged between these passage spaces are present, is switched to the on position. In this way can be achieved be that switching on the hood by the manual or driven adjustment of the slats is achieved.
  • the fins may be arranged so that they are between the body sides the extractor hood or between the frame or housing ein filedd or striking the carcase sides or the frame or housing are executed.
  • the slats in a closed position in lie substantially in one plane and in at least one open position in one Angle to the suction are employed.
