Definitions

  • the object of the present invention is a suction hood the main structural components whereof are seated inside a single compact structure.
  • the present invention relates to the field of suction hoods intended for eliminating smoke and vapours produced to the environment.
  • cooker hoods in particular household cookers, are intended for eliminating smoke, odours and vapours (hereinafter globally referred to as "cooking smoke” for shortness of description) coming from the underlying cooking top, in order to vent them to the external environment and/or purify them with special carbon filters.
  • a hood may also have further additional components, not essential from the functional point of view, but by now almost always present in the most widespread hoods, and generally consisting of:
  • hoods are known in the reference field, which aim at decreasing the space required for said structural components, providing for the arrangement thereof into modular units side by side or superimposed on one another or positioned in different zones and away from the hood.
  • suction hoods which are provided with a modular structure and combining the function of filtering unit and lighting unit, the suction unit instead being positioned at the top or even placed outside the building.
  • a significant advantage is obtained with this kind of hood in terms of reduction of space compared to the hoods known so far, however there is still the drawback of having to provide a structure capable of seating separate units, at least for the filters and for the motorized air conveyor.
  • the separate arrangement, in generally vertical line, of the filtering unit and of the suction one causes certain efficiency reduction in the hood suction capacity.
  • the object of this invention is to overcome at least a part of the drawbacks described above, by providing a suction hood having all the main structural components in a single and compact unit.
  • reference numeral 1 indicates the single-block hood as a whole, the structure whereof consists of a support frame 1 suitable for supporting and seating all of the hood functional components.
  • Said support frame 1 is shaped as a parallelepiped provided with vertical 1.1 and horizontal 1.2 uprights that define the framework thereof.
  • the support frame 1 is shaped as a cube, the framework whereof, consisting of the vertical 1.1 and horizontal 1.2 uprights, therefore defines six faces; however, nothing prevents the provision of a support frame 1 having any other geometrical shape, such as for example a cylinder or a polyhedron with a pentagonal, hexagonal base, etc., in such cases it being enough to provide for the other component elements to have a shape suitable for being supported and seated by said frame 1, differing from that shown in the annexed figures but in any case falling within the scope of protection given by the present invention.
  • the lower and upper base faces of said support frame 1 are respectively occupied by a box element consisting of a module 4, containing the lighting unit 5 and the control means 4.1 of the hood, and by a closing panel 1.3, whereon there is obtained an opening 6 for coupling the venting conduit of the cooking smoke, not shown in the figure.
  • the side walls of the support frame 1 are occupied, at least some but preferably all, by filtering panels 2, that therefore are the filtering unit of the hood.
  • Said filtering panels 2 are constrained to the support frame 1 by known coupling means, such as for example tabs engaging in special slits obtained on the horizontal uprights 1.2.
  • said filtering panels are of the so-called anti-grease type, and they usually consist of multiple superimposed layers of a metal mesh obtained from thin aluminium sheets.
  • Such type of filter offers a relatively low resistance to the passage of air, at least as long as it is clean, and it is easy to maintain as it may be washed in a dishwasher too.
  • Reference 3 indicates the suction unit represented by a common motorized air conveyor, optionally resting on an underlying support bracket 3.1 secured to the support frame 1.
  • Said air conveyor 3 may be fixed by known means to the lower part of the closing panel 1.3 and its outlet is associated to the opening 6 obtained on said closing panel 1.3.
  • the motorized air conveyor 3 preferably consisting of a usual half-screw and dual impeller fan, may be of any desired power, for example 250 to 1000 m 3 /h.
  • the compact single block represented by the support frame 1 seats and supports all of the functional components of the hood:
  • the suction unit is not positioned outside (generally at the top) the filtering unit, but therein, being surrounded by the filtering panels 2 positioned on all or some of the side walls of the support frame 1.
  • the cooking smoke flows towards the filtering unit in centripetal direction from all or some of the side walls provided with filtering panels 2.
  • a second order of advantages may be found in the improved suction efficiency provided by such innovative solution: the fact that the motorized air conveyor 3 is positioned inside the single block and preferably entirely surrounded by the vertical filtering panels 2, allows all of the cooking smoke to be sucked into the single block through a considerable larger side suction zone (and substantially equal to the sum of the surfaces of such vertical filtering panels 2) compared to what occurs according to the prior art, where only one face of the hood, generally the lower one, is used for seating the filtering unit.
  • the single-block structure 1 described above may safely entirely act as suction hood, without the need of providing further component elements, but the usual venting conduit of the cooking smoke sucked which fits on opening 6 obtained on the closing panel 1.3 (said venting conduit may also be used as carrying structure to be fixed to the ceiling, in the case of a hood for an island structure).
  • said single-block structure may also be coated with special aesthetic covers, having the main function of design elements and to a smaller extent, of means for facilitating smoke conveying towards said single-block structure.
  • the single-block structure 1 needs not necessarily consist of a cubic-shaped parallelepiped, as it may have any geometrical shape, with the functional components sized and shaped accordingly.
  • the support frame 1 may be of cylindrical shape and the filtering panels 2 may consist of a single cylindrical panelling or multiple curved filtering panels which, side by side, cover the cylindrical wall of said support frame.
  • the filtering panels 2 need not occupy all the side walls of the support frame 1, for completely surrounding the motorized air conveyor 3, as they may well occupy only some of these side walls or also be placed in the front face of said support frame 1.
  • a hood in suction mode only has been described, the same teachings may be easily applied to a hood in filtering/purifying mode, proceeding to the replacement of the filtering panels 2 or adding suitable active carbon filters thereto.
