Definitions

  • the invention relates to a vapor extraction device, in particular an extractor hood for the recirculation mode, with a housing in which at least a first filter and at least one fan are arranged, wherein in the vapor extraction device at least one channel for guiding the Wrasens or vapor is formed by the housing.
  • a known vapor extraction device is that of the Miele & Cie. KG, hingesloh, Germany Distributed extractor hood for recirculation (circulating air hood) with the designation DA 424-4.
  • This air vent has as the first filter metal grease filter, which are attached to a suction port of the channel in the housing.
  • these metal grease filters absorb solid constituents of the vapor, for example fat, dust or else. As a result, contamination of the interior of the hood is largely avoided.
  • the metal grease filters are reusable. They only need to be rinsed when dirty, for example in a dishwasher.
  • the cooker hood DA 424-4 has an odor filter.
  • the odor filter is placed in the duct through the extractor hood behind the first filter.
  • the odor filter binds odors during cooking.
  • the odor filter is not reusable and must be replaced at regular intervals to maintain the filter effect of the cooker hood.
  • odor filter Access to the odor filter is possible when the metal grease filters are removed from the housing of the cooker hood. Then it can be passed through the suction port for removing the odor filter in the channel.
  • the fan of the hood is arranged, which can build the pressure necessary for the transport of Wrasens through the channel.
  • the designer of the extractor hood is restricted for the appearance of the extractor hood.
  • the designers want more freedom in designing the appearance of the cooker hood.
  • the invention thus raises the problem, a Wrasenabzugvorraum of the type mentioned in such a way that the order of the various, along the channel attachable components for increasing the design options is more freely selectable.
  • the at least one underpressure-side section and the at least one overpressure-side section of the channel are separated from one another by the separating means, apart from the connection by the blower. According to the invention, it is sufficient if the separation between the at least one vacuum-side section and the at least one overpressure-side section of the channel takes place only in part through the separating means. It is not necessary that the duct sections away from the blower be separated at any point by the separating means. Apart from the separation by the separating means, other means of separating the sections are also possible. But it is possible that the negative pressure side portion and the overpressure side portion of the channel are separated from the fan only by the separating means.
  • the release agent may now be moved or removed by a user as indicated in claim 2, so that a connection between the at least one vacuum-side portion and the at least one pressure-side portion can be easily made.
  • This connection can now be used to access at least one second filter in the at least one overpressure-side section via the at least one underpressure-side section in a variant of the vapor extraction device as circulating hood.
  • the release agent may be fixedly mounted in the housing, since access to the at least one overpressure-side section is not necessary. It is useful if the release agent can be moved or removed after releasing a lock by a user, without the need for a special tool is necessary. Solving the Locking should be possible by any average consumer and not just by a specialist.
  • the arrangement of the fan between the at least one first filter and the at least one second filter can thus take place, which increases the freedoms for the outer design of the device.
  • the at least one release agent may be a sheet metal blank which may have been folded one or more times. It is also conceivable that the release agent is a plastic part, for example an injection molded part.
  • the at least one separating means preferably has a plate-shaped section. The vapors transported by the blower can strike directly on the plate-shaped section in the case of such a release agent on the vacuum side as well as on the overpressure side. The direction of Wrasens on the negative pressure side and the pressure side can be opposite in the projection on the plate-shaped portion.
  • a vapor extraction device may have a holding means for the at least one second filter.
  • the at least one holding means may be movable, in particular removable, slidable and / or pivotable, for example, for insertion and / or removal of at least one of the second filters.
  • the at least one release agent of a vapor extraction device according to the invention can be connected to the at least one holding means.
  • the separating means and the holding means are advantageously jointly movable, in particular removable, slidable and / or pivotable.
  • the holding means preferably has openings through which the vapors transported through the housing can be moved.
  • connection between the release agent and the retaining means may be made by webs.
  • the webs can be perforated.
  • a spacer which is preferably made by a punched out of the holding means and folded tab.
  • the distance between the release agent and the holding means may be the same at any point in a vapor extraction device according to the invention. However, it has been found that, for reasons of improved Wrasen Entry or pressure distribution in the space between the release agent and the retaining means, the distance between the release agent from a fan facing the end of the unit of release agent and retaining means decreases to a side facing away from the fan end.
  • the at least one first filter can obstruct and / or cover access to the separating agent. So that access to the separating means is possible, the at least one first filter may be movable, in particular slidable and / or pivotable, and / or be removable from the housing. Additionally or alternatively, it is possible for the at least one second filter to obstruct and / or cover access to the release agent. So that access to the separating means is possible in this case, the at least one second filter may be movable, in particular slidable and / or pivotable, and / or be removed from the housing.
  • the at least one channel of a particular vapor extraction device according to the invention may have two vacuum-side sections, which are brought together in a fan section of the channel, wherein in the fan section, the at least one fan is arranged.
  • a vapor extraction device according to the invention it is possible for a vapor extraction device according to the invention to have a channel with two overpressure-side sections which branch off from a fan section of the channel.
  • the fan section may be arranged not only relative to the flow path but also relative to the housing between the two vacuum-side sections and the two overpressure-side sections. As a result, the overall height of the housing can be reduced to a particular extent.
  • the first filter may be a grease filter or an odor filter. The same applies to the second filter.
  • the vapor extraction device has a housing 10 which can be suspended by means of a suspension device, not shown, on a ceiling.
  • a blower (not shown) is provided, with which on a suction side of the housing 10, it is the bottom of the housing 10, a negative pressure and on a discharge side of the housing 10, which is the top of the housing 10th , an overpressure can be generated.
  • the housing 10 is designed with respect to the parts that affect the flow through the housing 10 surface symmetry. That which in the FIGS. 4 to 6 to a right half of the housing 10 is also found in a left half of the housing 10. The following description refers to the right half of the housing 10. It can be easily transferred to the left half.
  • the housing 10 has on the bottom of the grease filter 2, z. B. from a wire tangle or wire mesh. These grease filters 2 close the bottom of the housing 10 largely. The grease filters 2 are inserted into a suction port 13 of the housing 10. The grease filters 2 can be removed for cleaning, among other things.
  • a passage from the suction port to exhaust ports at the top of the housing is provided.
  • the exhaust openings 18 are formed by openings of a perforated grid, which is part of the housing.
  • the negative pressure side section 12 is connected to a fan section 14.
  • the fan (not shown) is arranged.
  • the fan section 14 is both part of the airway through the left part of the housing 10 and through the right part of the housing 10.
  • a protective grid 15 is arranged, which prevents the case removed from the housing 10 grease filters 2 that objects or limbs are inserted through the negative pressure section 12 in the fan section 14 and damaged or injured by fan blades or other possibly rotating parts become.
  • a protective grid 16 is provided for the same reasons.
  • a pressure-side section 17 of the channel adjoins behind the fan section 14.
  • the air flow from the housing 10 can escape.
  • This release agent 20 is pivotally mounted in an axis 200 and can be folded down with removed grease filters 2.
  • a filter cartridge 19 with the odor filter 3 is arranged in the overpressure-side portion 17 of the channel as a holding means for the odor filter 3.
  • the filter cartridge 19 has openings 190 through which the vapors transported through the housing can be moved.
  • the odor filter 3 may be an activated carbon filter.
  • the filter cartridge 19 is connected to the separating means 20 and is pivoted downwardly therewith. When the release agent 20 is folded down ( Fig. 5 ), the odor filter 3 can be removed from the filter cassette 19 ( Fig. 6 ) and be replaced by another odor filter 3.
  • the separating means 20 and the filter cartridge 19 serving as a holding means comprises webs 201 which connect a plate-shaped portion 202 of the separating means 20 and the filter cartridge 19.
  • the webs 201 may have holes through which a flow can pass.
  • the webs are preferably arranged laterally.
  • a spacer 191 which is made by punching and folding from the holding means.
  • the distance between the separating means 20 and the holding means decreases with increasing distance from the fan, resulting in a uniform pressure distribution in the space between the separating means 20 and the holding means.
  • the uniform pressure distribution then allows a uniformly distributed flow through the second filter.
