Definitions

  • the present invention relates to an extraction device for removing air from an area above a cooking hob according to the pream- ble of claim 1. Further, the present invention relates to an ex traction system for removing air from an area above a cooking hob according to claims 1 and 16. The present invention relates further to a combination appliance according to claim 25. Fur ther, the present invention relates to a system comprising a cabinet and an extraction system according to anyone of the pre ceding claims 1 to 24. Finally, the present invention relates to a cabinet, in particular a kitchen cabinet, according to claim 29. During the performance of cooking activities under use of a cooking hob, cooking vapours are generated, which are distrib uted over the cooking area.
  • an ar rangement of an extraction device is common.
  • Said extraction device is operated in parallel to the cooking hob, thereby sucking in those cooking vapours in order to filter out particles and tiny droplets from the vapours and/or to blow the vapours to the outside of the building.
  • an extractor hood While it has been common to arrange such an extractor hood above the cooking area, in recent years downdraft extraction devices have been finding a growing market.
  • Such kind of extraction device is usually arranged below a worktop of the related cooking hob and it comprises at least one fan for sucking air from the cooking area through an opening or recess arranged in the worktop.
  • the respective airflow is commonly guided by means of an air channel system and a related air duct is installed inside the kitchen cabinet, which also accommodates the extraction device. It is common to place the air duct, notably a vertically aligned section thereof, close to a rear wall of the cabinet. Said air duct usually has a circular or rectangular shape and is in- stalled in the cabinet by a kitchen installer.
  • a kitchen planner has to consider that the related space has to be provided, what com monly results in a provision of specific kitchen drawers, which are shortened compared to standard drawers. Naturally, such shortened kitchen drawers can also provide only a respectively reduced storage space.
  • the object is achieved by an extraction system for removing air from an area above a cooking hob according to the features of claims 1 and 16.
  • the extraction system includes an extraction device and an outlet air channel.
  • the extraction device com- prises an inlet opening for an air intake into an interior of the extraction device, a conduction means for conducting the air through the interior of the extraction device and an outlet con nection piece connected to a channel input of the outlet air channel.
  • the outlet air channel is configured for transmitting exhaust air from the channel input to a channel output that is provided for blowing out the exhaust air, in particular into room air or ambient air.
  • the outlet air channel includes at least a first component or a first section of its entire length with a cross-sectional area and/or a passage area for air passage, which cross-sectional area and/or passage area extends or extend in a first direction and in a second direction orthogonally to the first direction, wherein the ratio of the extension or dimension in the first di rection to the extension or dimension in the second direction is at least 3 to 1, preferably at least 5 to 1, more preferably at least 10 to 1.
  • the key aspect of the solution according to the present inven tion is based on the consideration that reducing the depth of the outlet air channel of the extraction system arranged inside the cabinet can prevent a loss of storage space in the cabinet, specifically when a provision of shortened drawers for the cabi net can be avoided that way. Moreover, as a compensation for the reduction of the channel depth, the channel width may be in creased in order to provide a sufficient cross-section for an unhindered airflow.
  • the depth of the outlet air channel is notably reduced, i.e. a flatter outlet air channel is provided, so that a loss of storage space in the cabinet due to the outlet air channel installation is minimized and particularly drawers having a significant length, especially standard drawers, may be used.
  • the air removed from the area above the cooking hob is particu larly heated air and the air may comprise cooking vapours.
  • the extraction device is particularly an extraction hood for the ex traction of cooking vapours. More particularly, the extraction device is a downdraft extraction hood, which is implemented in the cabinet, particularly below and specifically attached to the cooking hob.
  • the extraction device preferably further comprises a fan for sucking in the air, notably the cooking vapours, from the area above the cooking hob. Said fan is arranged in or is in opera tive connection with the conduction means.
  • the extraction device especially includes also a filter means for filtering out parti cles and droplets of the cooking vapours, in that performing an air-recycling process.
  • the conduction means is particularly an air duct.
  • the outlet air channel design may be characterized by any arbi trary flat shape of construction, but in particular the cross- sectional area or passage area of the outlet air channel is rec tangular or oval-shaped.
  • the first component or first section is particularly positioned or positionable at least close to at least one wall of a cabinet for accommodating the extraction system. More specifically, the component or section is attached or attachable to or positioned or positionable adjacent to the at least one wall. This specifi- cally supports the space utilization to an even greater extent, since unnecessary loss of space is avoided by moving even closer to the wall, notably by reducing the distance to the wall to zero.
  • the first component or first section may be attached to or posi tioned or positionable adjacent to an inner surface of the wall, so that the first component or first section is arranged in the cabinet interior.
  • the first component or first section may be attached to or positioned or positionable adja- cent to an outer surface of the wall, which will further in crease the storage space of the cabinet, since the entire cabi net depth of a standard cabinet is provided that way.
  • the outlet air channel needs to penetrate the wall and a respective cutout has to be implemented by a kitchen in staller .
  • said first component or first section forms or is designed or configured to form at least a part of at least one wall of the cabinet.
  • the at least one wall is at least one of a side wall, a rear wall and a bottom wall of the cabinet.
  • the se lection of the most suitable wall may particularly depend on the design of the extraction device, notably the respective arrange ment of its outlet connection piece, or it may depend on the po sitioning or fixation of interior equipment.
  • the first component or first section or a wall ele ment comprising the first component or first section is designed and/or configured for replacing a wall of a standard cabinet.
  • a standard cabinet e.g. a standard kitchen cabinet
  • the kitchen planner may be selected by the kitchen planner without having to con sider the installation of the extraction system therein. Only the kitchen installer has to consider that, however, this person anyway needs to install the outlet air channel, which is merely different but not necessarily more elaborate than with the in- stallation of outlet air channels according to the state of the art.
  • a particularly preferred choice of a suitable wall is the rear wall of the cabinet. The positioning of an out let air channel according to known solutions is back-mounted as one favourite solution.
  • the bottom wall may be a suitable object for serving at least partly as a channel.
  • a particularly ad vanced solution according to the present invention provides for an implementation of the first component or first section of the outlet air channel both in the rear wall and in the bottom wall of the cabinet, which may particularly be the result of a re- spective special designing of the cabinet.
  • a particularly specific embodiment is characterized in that the first component or first section or the wall element comprising the first component or first section forms a replacement of the rear wall of a standard cabinet and comprises at least one lat erally arranged tongue configured for being inserted in a groove of a side wall of the cabinet. Said groove for receiving the laterally arranged tongue is particularly the groove provided for a standard cabinet rear wall. More specifically, the tongue is integrally designed with the first component or first section or the wall element comprising the first component or first sec tion. An even more preferred solution provides for an arrange ment of tongues both at the left side and at the right side of the first component or first section or the wall element com- prising the first component or first section.
  • the first component or first section or the wall element comprising the first component or first section may comprise at least one laterally arranged groove configured for receiving a first lat eral edge of a tongue.
  • a second lateral edge, which is opposite to the first lateral edge, of the tongue is configured for being inserted in a groove of a side wall of the cabinet, particularly in the groove provided for standard cabinet rear wall, specifi cally in the case of said standard cabinet rear wall being re placed by the first component or first section or the wall ele- ment comprising the first component or first section during the kitchen installation process. That way, the tongue, on the one hand, and the first component or first section or the wall ele ment comprising the first component, on the other hand, are pro vided as separate elements.
  • This modular conception particularly facilitates adaptation to specific applications, notably cabinet applications .
  • the first component or first section or the wall element comprising the first component or first section may be adaptable to the width of the cabinet by adjusting the width of the tongue.
  • Said adap tion is particularly performed by a tongue that is designed in that its lateral extension is reducible, specifically by longi- tudinally cutting the tongue.
  • Said tongue being a component separate from the first component or first section or the wall element comprising the first compo nent or first section, may not even be a specifically designed component.
  • first component or first section or the wall element comprising the first component or first section may allow the use of the standard rear wall to be replaced as a provider for the creation of the tongue, nota bly on-site, i.e. by the kitchen installer during the kitchen implementation process.
  • This can be realized in that the kitchen installer cuts off a section, i.e. a strip, of the standard rear wall, resulting in the provision of in individually designed and adjusted tongue.
  • a second tongue preferably of the same dimensions, may be produced in the same way in order to get tongues for an application at left and right sides.
  • first component or first section or wall element comprising the first component or first section, which is designed as a metal lic component.
  • a preferred selection therefore is aluminium.
  • This type of metallic material is particularly suitable for a lightweight design, and it is easily formable. More specifi cally, a manufacturing by an aluminium extrusion is an advanta geous manner of preparation.
  • the first component or first section or wall element comprising the first component or first section may be designed as a plastic component, which may be manufactured by an injection moulding, a blow moulding or a plastic extrusion process.
  • a further enhanced embodiment with an even further increased adaptability is provided in that the first component or first section or the wall element comprising the first component or first section is manufactured with an excess length of arbitrary longitudinal dimension and adaptable to the length required for each specific application.
  • Said adaptation to the specific ap plication is preferably executed by cutting a product resulting from an open length production to the required length.
  • a product manufactured by continuous casting process may be favourable.
  • the first component or first section or the wall element comprising the first component or first sec tion includes at least one supporting rib keeping opposite chan- nel walls at a distance from each other.
  • a single supporting rib is particularly centrally arranged and at least two supporting ribs may be evenly distributed over the lateral extension.
  • Said at least one supporting rib may be favourable with regard to a prevention of the opposite walls to converge, hence causing a reduction of the channel cross-section.
  • a bal looning effect can be prevented with said supporting rib, which effect may occur because of an excess pressure caused by the op eration of the fan of the extraction device along with a slowed air discharge.
  • the first component or first section or the wall element com prising the first component or first section may be connected or connectable to a deflection element, which connection is ar ranged at its top end.
  • the deflection element may be arranged or arrangeable at the bottom end of the first compo nent or first section or of the wall element comprising the first component or first section.
  • a specifically preferred solu tion is characterized by a first and a second, i.e. an upper and a lower, deflection element connected to both the top and the bottom ends of the first component or first section or of the wall element comprising the first component or first section.
  • Such a deflection element is designed to provide or configured for providing a redirection of the airflow of the transmitted exhaust air by at least approximately 90 degrees.
  • Top and bottom ends in the context of the present solution may mean a channel entry and exit. Such kind of redirection may be a horizontal to vertical deflection and/or vice versa.
  • a specific embodiment of the present invention is characterized in that the outlet connection piece of the extraction device has a cross-section compatible to the cross-section of the channel input of the outlet air channel.
  • This is favourable at least for the deflection device at the top end of the first component or first section or of the wall element comprising the first compo nent or first section. That way, an easy connection, specifi cally by means of a slide-in connection, is realizable.
  • an adapter piece may be interposed between the outlet connection piece and the channel input of the outlet air chan nel, which adapter piece is designed to perform a cross-section adjustment between the outlet connection piece and the channel input of the outlet air channel. Using such an adapter piece may render it unnecessary to modify existing extraction devices, such as those ones that are combined with common, i.e. state of the art, outlet air channels.
  • the channel output of the outlet air channel is spaced or configured or designed to be spaced from a plinth area, in particular from a plinth panel arranged in the plinth area, of the cabinet with a distance of at least 5 cm, preferably at least 10 cm, more preferably at least 20 cm, most preferably at least 30 cm.
