Definitions

  • the invention relates to a device for dispensing an odor-destroying substance into an air flow generated by a fan, in particular in kitchen extractor hoods, with a reservoir for the odor-destroying substance that can be connected to the air flow.
  • Extractor hoods especially kitchen extractor hoods, are today usually equipped with an activated carbon filter to remove odors, which is attached in front of the suction grille of the suction fan.
  • activated carbon filters A disadvantage of the use of activated carbon filters is that, on the one hand, they greatly increase the flow resistance of the entire extractor hood, which leads to overdimensioning of the suction fan, and, on the other hand, the mode of operation of such filters is controversial.
  • the oversizing of the suction blower also leads to an additional noise pollution of the environment, on the other hand, a degree of saturation or a controlled monitoring of the filter effect with activated carbon filters is not possible.
  • the object of the invention is to provide a device with which an odor-destroying substance can be introduced into an air flow, in particular into the suction flow in kitchen extractor hoods. Refillability should also be ensured, as well as reducing the flow resistance to a minimum in order to be able to use smaller fans.
  • a reservoir within the air flow has the advantage that its design can be made such that simply by sweeping the sucked-in air, which contains the undesirable odorous substances, an odor-reducing or reducing substance can be introduced into the air flow without the high levels of suction fan performance required in the prior art.
  • these odor-destroying substances it can z. B. are solid particles, gases, but especially liquids.
  • the invention provides that the reservoir is designed as a vessel that is open on one side with a filling that absorbs the odor-destroying substance, and that the guiding elements are designed as a wall with through-openings that cover the vessel at a distance, whereby being particularly special has expediently put out if the vessel is designed as an open circular gutter with a felt filling which is covered concentrically at a distance from the hood-shaped wall, which on the one hand provides a comparatively large reservoir, and on the other hand the shape of the gutter gives the possibility of by-pass Flow openings must be provided which greatly reduce the flow resistance of the entire device.
  • the hood-shaped wall forms the guide element for the air flow and, depending on requirements, can be designed like a nozzle or the like in order to achieve the necessary flow velocities past the reservoir.
  • the invention provides that the hood-shaped wall is designed as a flat plate with upstream edges and with openings arranged in segments, which can optionally be opened and closed by a concentric cover plate.
  • the air flow through the device can be increased or decreased by opening or closing the openings through the cover plate, which leads to an economical use of the liquid, odor-killing substance.
  • a structurally simple solution consists in that the vessel and the hood-shaped wall can be fastened concentrically to a common fastening element within an air flow channel, it also advantageously being possible for a suction gap, which tapers downstream, to be formed between the vessel and the hood-shaped wall .
  • the device elements that is to say in particular the setting of the suction openings and thus the amount of the air stream flowing past the reservoir, can be regulated and controlled automatically. However, it can be useful to do this from the housewife herself to be carried out.
  • the invention provides in a very simple embodiment that the attachment is arranged concentrically on the intake grille of the fan of a kitchen extractor hood, the cover disk controlling the segmentally arranged openings in the hood-shaped wall partially permeating the housing wall of the extractor hood for optional adjustment of the flow cross section.
  • the cover plate has a filling opening for refilling liquid odor-eliminating substance into the felt filling of the vessel, which corresponds in at least one position to an opening in the hood-shaped wall for refilling.
  • the container for the odor-destroying substance is equipped with a device for indicating the fill level.
  • This regulation or display can, for. B. by moisture sensors or by weight differences between filled and empty reservoir.
  • the reservoir z. B. is suspended via a spring in such a way that when the fill level is unfavorable, electrical contacts close via the spring, which are held in the open position by the weight of the odor-suppressing substance when filled.
  • the device is attached to the suction grille of a suction fan within an extractor hood.
  • the attachment is made such that an adjustable gap remains for the passage of untreated air between a cover plate of the device described in more detail below and the intake grille.
  • the device essentially consists of a hood-shaped wall which is arranged concentrically around a central axis and is designed as a flat plate and has an upstream edge which covers a reservoir which is arranged concentrically on the inside thereof.
  • the reservoir is in the form of an annular groove which is open downstream and has a felt filling and is fastened axially displaceably to the central axis.
  • the outer wall of the reservoir forms with the edge of the hood-shaped, plate-like cover wall an annular flow channel that tapers downstream.
  • the covering wall is equipped with segments, preferably 60 "segments, with openings which can be partially or completely closed in the cover by means of corresponding segments.
  • the hood-shaped wall is equipped with a filling opening for refilling a liquid odor-destroying substance, the cover plate also having is equipped with at least one corresponding opening, for example in the form of an uncovered segment section.
  • a level indicator which is carried out by gravity
  • two electrical contacts are provided, which are kept apart by the weight of the reservoir filled with the odor-killing liquid.
  • a spring acts against gravity and tries to lift the reservoir in the direction of contact. If the smell-destroying liquid is gradually used up, the weight of the reservoir becomes lower, i. H. the spring can lift the reservoir. If the fill level falls below a certain level, the other contact comes into contact with the first contact and closes a circuit which, for example via an optical or acoustic display, shows the user of the device that the required fill level has been undershot, so that refilling is necessary.
  • this is larger in diameter than the largest diameter of the device and passes through a part of the housing of the extractor hood.
  • Corresponding markings on the edge area of the cover plate can be used to make the user recognizable from the outside in which setting state the device is.
  • the described embodiment can be modified in many ways without departing from the basic idea of the invention.
  • the invention is not restricted to a special shape of the reservoir and an arrangement within the device.
  • a larger-area, impregnable felt disk or the like can be provided.
  • Individual vessels arranged in a star shape can also be arranged below a common hood, the assignment of which to the air flow can be changed in each case.
  • the invention is in particular not limited to a special level indicator.
  • sensor elements can be provided that react to moisture, to organic substances or e.g. B. on the evaporation resulting from evaporation. Like. More.
