Definitions

  • the invention relates to a filter cassette for extractor devices according to the preamble of claim 1.
  • Extractor hoods are used to clean the cooking, roasting, baking, Grilling, deep-frying, etc., hereinafter generally referred to as cooking, arise fatty air.
  • the invention is suitable for circulating air extractor hoods (air recirculation in the Cooking room) and for exhaust air food (extraction of the vaporous air from the cooking room in an outside atmosphere).
  • Non-woven filters with a non-woven filter mat made of plastic fibers are known from the prior art known with and without pollution saturation indicator.
  • the Fleece filter mat becomes saturated when a certain contamination is reached replaced by a new one.
  • Washable fleece filters are also known, which consist of a fleece filter mat Contain plastic fibers that can be washed out in a dishwasher. It is not dimensionally stable, but very flexible. The disadvantage is that the customer Fleece filter mat does not normally wash out, but throws it away and through a new ones replaced. You don't have a pollution saturation indicator because of this normally consists of a dye which is washed out when the fleece filter mat is washed out would also be washed out in a dishwasher.
  • metal filters There are also metal filters. They usually consist of six to twelve layers Expanded metal. Such metal filters can be washed out in a dishwasher. A disadvantage is their high weight.
  • DE 41 38 845 C2 includes an extractor hood device for recirculation mode a rectangular grease filter cartridge known.
  • the grease filter cartridge is on yours Provide underside with a filter grid with openings.
  • As a lid a panel with openings is provided, between which non-open Areas are larger than the breakthroughs.
  • the aperture is there made of heat-resistant plastic or metal.
  • In the dark flow path between The filter grille and the cover are made of fleece or made of grease filter material Expanded metal. Through the non-perforated areas of the aperture, one should more uniform grease separation of the vapor flow over the grease filter cross-section can be achieved.
  • There is a blower on the downstream side of the filter cassette arranged to generate the vapor flow through the fume extractor. Downstream of the blower there is an odor filter, according to which the cleaned vapor flow is returned to the room from which the vapor is suctioned off.
  • the filter cassette according to the invention can also be used in combination with a Odor filters are used. It usually contains activated carbon or zeolite for odor adsorption.
  • the object of the invention is to achieve a filter cassette for extractor devices to train such that they are dimensionally stable and therefore easy to handle and washable in a dishwasher are for regeneration like the grease filters consisting only of metal, but in In contrast to this a lower weight and an equally good or better Have filter efficiency. There should also be the possibility of a pollution saturation indicator to be able to use.
  • the filter cassette is characterized according to the invention in that a grease filter made of non-metallic material in the vapor flow path between two with Gap filters made of metal are arranged at a distance from one another form the top sides of the filter cassette.
  • the known grease filters in the form of nonwoven mats are used in extractor devices usually on a perforated sheet or grid or between two Perforated sheets or grilles placed, which are attached to the extractor hood and so that they are an integral part of them.
  • For washing out or replacing the nonwoven mat is removed from the extractor device, whereby the perforated plate or the grid remains in it and is only laborious in it, insufficient and can be cleaned with a lot of time.
  • This disadvantage will also resolved by the invention, because according to the invention the deck sides the flexible grease filter mass together with this form a cassette, which Removable from the extractor hood and in a dishwasher is washable. This eliminates any remaining in the extractor device Grids or perforated plates that pollute by the haze current and only can be cleaned laboriously and insufficiently.
  • the metal grease filters are preferably made of expanded metal and each of the two Cover sides preferably consist of at least one layer of expanded metal.
  • the filter material of the non-metal grease filter preferably consists of fibers, e.g. B a fleece, or made of open-cell foam.
  • the non-metal grease filter is between the metal grease filters are arranged interchangeably.
  • the Non-metal grease filter from a washable in a dishwasher and thereby regenerable material. If he additionally between the two Metal grease filters are interchangeably arranged, it can also from time to time be replaced.
  • an indicator element provided to display the contamination saturation of the filter arrangement.
  • an indicator element can be used before or after each washing of the filter cartridge be replaced or from one together with the filter cassette or separately consist of this washable element, which by such washing is regenerable and reusable. This will, for example Operating hours counter avoided, as are known in the prior art, to replace the grease filter after a certain number of operating hours or wash out.
  • the filter cassette on at least one extending transversely to the two deck sides Edge side at least one extendable and retractable locking element for attaching the filter cassette to an extractor hood, and on a a handpiece for manual actuation of the locking element on both sides of the deck.
  • Edge side at least one extendable and retractable locking element for attaching the filter cassette to an extractor hood, and on a a handpiece for manual actuation of the locking element on both sides of the deck.
  • the dimensionally stable filter cartridge 1 consists of a metal frame 2, two top layers 4 and 6 each of at least one layer Expanded metal as a grease filter, and a filling 8 made of non-metallic filter material as a grease filter.
  • the non-metallic filter material 8 can be washed out Fibrous material, e.g. B. a fleece filter mat, or an open-pore filter foam his.
  • Fibrous material e.g. B. a fleece filter mat, or an open-pore filter foam his.
  • other heat-resistant material can be used be used, which with a large variety of close to each other Is provided openings at the edges of an essential Fat separation is generated from a vapor stream
  • each cover layer 4 and 6 only from a single layer of expanded metal.
  • the filling is preferably also only from a single layer of washable non-metallic Material.
  • a flake-shaped indicator element 12 is provided be, which according to an arrow 14 in an opening 16 of the filter cartridge 1 can be used and therein, for example, by a fastening ring 18 is held.
  • the pollution saturation indicator element 12 can be installed interchangeably in the filter cassette 1. Alternatively, you can built-in, d. H. non-exchangeable indicator elements 12 are used be put together with the filter cassette in a dishwasher are washable and therefore regenerable.
  • the filter cassette 1 can be inserted into a socket of an extractor device become. Alternatively, it can be turned away from two Edge pages 22 and 24 each have at least one, preferably two projections 26, 27, 28 and 29, through which the grease filter cassette on contact surfaces can be placed in an extractor hood. So that a receiving opening the extractor device for the filter cartridge 1 is not significantly larger at least one protrusion is to be the periphery of the rim 26, 27 extendable and retractable on one edge side 22 relative to the latter arranged.
  • the extendable and retractable are preferred Projections 26 and 27 by spring means 32 in the extended, in the Drawings held position shown and they can counter the spring force manually retracted at a handle 30. After letting go of the handle, they are automatically extended again by the spring means.
  • the spring means 32 are, for example, a spiral spring or leaf spring.
  • the handle 30 is located on one of the two deck sides of the filter cassette.
  • Fig. 5 shows schematically in cross section an extractor device with a Fat filter cassette 1 according to the invention. Can downstream of this
  • an odor filter 40 can be arranged to remove odors contains, for example, activated carbon or zeolite from the vapor stream.
  • a fan 42 can in the flow path between the fat filter cassette 1 and the odor filter 40 or, according to FIG. 5, downstream of the odor filter 40 be arranged. Cooking fume sucked in by the fan 42 from one The hotplate, not shown, is represented by an arrow A. The through the Filter devices 1 and 40 cleaned air A1 reappears in recirculation mode into the room in which the extractor hood is located.
