Definitions

  • the invention relates to a fume extraction device and a method for cleaning kitchen air.
  • a fume hood from DE 92 08 718 U1 in which the sucked air is passed through an air duct with an air switch.
  • a disadvantage of this extractor hood is that it is designed for operation as an exhaust device. Switching to a recirculation mode takes place only temporarily, if in the room in which the extractor is operated, there is a negative pressure. Due to the intended switch, recirculation of the recirculated air into the room takes place only partially, while at least temporarily a substantial part of the air is released into the environment.
  • Object of the present invention is thus to provide a simple way to a way that can be cleaned efficiently with the kitchen air.
  • the invention is based on the finding that this object can be achieved by a sufficient spatial separation of the intake opening and the exhaust opening of a fume extraction device.
  • the present invention relates to a fume extractor for mounting over a cooking surface, wherein the extractor device comprises a fume hood, which has an intake opening, an odor filter and at least one exhaust opening.
  • the extractor device is characterized in that the extractor device has an adjoining the extractor hood air duct in which the exhaust port is provided, the air duct between the extractor and the first exhaust port is completed and the exhaust port is spaced to the extractor.
  • the extractor hood according to the present invention may be a so-called flat screen hood, a substructure or intermediate hood or a dining, in particular wall or island fair.
  • Flat-panel hoods are usually integrated in an overhead cupboard of the kitchen while the food located above the suction opening extractor body is visible.
  • the suction opening may be surrounded by a vapor shield, can be passed through the contaminated air, in particular fumes and vapors to the suction.
  • a filter element is preferably provided in the suction opening. This
  • Filter element is a grease filter and may for example be a filter cartridge made of expanded metal filters.
  • a fan is provided behind the grease filter in the extractor, are pulled over the steam and vapor from below the extractor to the suction.
  • the extractor device comprises an odor filter, whereby the extractor device can be used as a forced-air extractor device.
  • the odor filter can be arranged in the flow direction behind the grease filter, for example between the grease filter and the fan of the extractor. As a result, a purification of the already pre-cleaned by the grease filter air can be ensured. But it is also possible, the
  • the air duct is a continuous closed air line.
  • an air duct is referred to, in which an escape or removal of air between the extractor and the first exhaust opening is not provided and not possible.
  • the exhaust opening is spaced from the extractor, the circulation of the air can be ensured particularly reliable.
  • the length of the air duct can be several meters. Preferably, however, the length of the air duct is limited to a maximum length, the operation of the Vapor extraction device even without the need for an additional blower for transport in the air duct allows.
  • the maximum length of the air duct can be for example 5m or 6m.
  • the exhaust opening according to the invention is not provided on the extractor but on the adjoining air duct, particularly large distances between the exhaust opening and the extractor hood, in particular the suction of the extractor hood can be realized, whereby the movement and circulation of the room air is improved.
  • the distance between the exhaust opening and the suction opening is limited in the extractor device according to the invention only by the dimensions of the room in which the extractor device is operated, in particular the kitchen dimensions. If the extractor device is to be operated without an additional blower, a maximum length of the air duct must also be taken into account.
  • the distance between the exhaust opening and the suction opening preferably corresponds to the maximum distance that is possible in a kitchen between the position of the extractor and the most distant from this position room corner.
  • the direction of the air duct deviates at least partially from the main flow direction in the extractor.
  • This configuration of the extractor device despite possibly existing spatial limitations, such as the ceiling, the largest possible distance between the exhaust port and the intake are realized.
  • the air duct can connect in the horizontal direction to a fume hood, in which the main flow direction is vertical.
  • the position of the exhaust opening is arranged horizontally offset from the surface of the suction opening.
  • the exhaust opening Due to the horizontal offset of the position of the exhaust opening to the surface of the suction opening the exhaust opening is at least in projection on a horizontal plane outside the surface of the suction.
  • the position of the exhaust opening may be in projection on a horizontal plane, for example, in front of or adjacent to the surface of the suction.
  • the circulating air is usually issued at the upper end of the so-called visual fireplace, which represents the extractor housing.
  • the exhaust opening is thus in the horizontal direction in projection within the surface of the suction opening. Due to the given by the dimensions of the space limitation of the length of the view chimney comes in this arrangement, the exhaust opening to a flow short circuit, in which the output air is sucked directly back into the extractor device.
  • the position of the exhaust opening relative to the surface of the suction opening is also arranged vertically offset.
  • the distance between the blow-out opening and the suction opening can be further increased.
  • direct impingement refers to an influx in which the air flow between the exhaust opening and the intake opening does not have to change direction. If, in addition, the spatial distance between the blow-out opening and the intake opening is large, the danger of sucking in the discharged air without circulating the remaining room air is further minimized.
  • the length of the air duct between the extractor hood and the outlet opening is greater than the vertical dimension of the extractor hood.
  • the vertical dimension of the extractor hood in this case comprises an optionally provided vapor shield and the vapor extraction housing arranged above the vapor shield.
  • the body is referred to, in which the fan and an optionally provided fan housing are added.
  • the extractor housing In an eating the extractor housing is usually through the viewing channel, which also as fireplace is called formed.
  • the air is only passed to the upper end of the extractor housing and discharged there into the room.
  • the vent guide of the extractor device according to the invention preferably comprises an air line which has at least one change in direction.
  • an air duct By using such an air duct, the exhaust opening can be brought within the room to a suitable location at which the circulation of the room air can best be ensured.
  • the air guide is attached to the upper end of the extractor, in particular the extractor housing. Attachment is understood in this context to be a connection of the air duct to the extractor hood, through which the circulated air is led out of the extractor hood into the air duct.
  • the vertical length available in the extractor housing is already used to transport the air away from the intake opening.
  • the vent guide is connected to the extractor housing so that the guided in the extractor housing air passes completely into the air duct.
  • the air line can be configured as a pipe or preferably as a flat channel.
  • a flat channel having a rectangular cross-section By using a flat channel having a rectangular cross-section, on the one hand, the structure of the entire extractor device can be kept simple.
  • the channel can be in one piece or consist of several channel pieces that can be assembled to form the air duct.
  • the transition from a chimney of a counter to the air duct can be made visually attractive.
  • a flat channel can be easily mounted on an overhead cabinet of a kitchenette or relocated there. When mounted on a wall unit or a top cabinet row, both installation and maintenance are particularly easy.
  • the air duct is but laid so that the exhaust opening of the extractor device, which is provided in the region of the end of the air duct, is not blocked by a wall or a panel.
  • the air duct may only consist of the air line in the extractor device according to the invention.

  • Vapor extraction device are directed in the assembled state of the extractor device in a common room, especially a kitchen. This means that the air duct runs neither through a room wall to another room nor through an outer wall. By introducing the circulating air into the same room from which the steam and vapor have been extracted, a circulation of the room air is reliably ensured.
  • the object is achieved by a method for cleaning cooking fumes and fumes from kitchen air.
  • the method is characterized in that sucked in a kitchen space to be cleaned kitchen air through an intake opening of a fume hood and cleaned in the extractor hood is then passed through a continuous closed air duct to a blow-out, which is spaced from the fume hood, and is discharged via the blow-out as circulating air in the kitchen space.
