Definitions

  • the present invention relates to the construction of aspirating kitchen hoods and in particular it concerns a hood filter to be mounted preferably in correspondence with the inlet section of gaseous substances into the hood.
  • aspirating kitchen hoods are provided with filters, positioned in correspondence with their inlet section, i.e. of the section for collecting the gaseous substances, which filters have a structure that is essentially constituted by a plurality of thin sheets of aluminium plate, appropriately holed, superposed in a stack and held together by a frame obtained from an aluminium section bar.
  • the frame is also provided, for fastening the filter to the hood structure in a removable fashion, with fixed hooks and with a small handle with movable latches, whose operation allows to secure or release the filter to and from the hood to enable washing or replacing the filter.
  • a first drawback of filters of the kind described above is due to the fact that the composite and monolithic structure of the filter allows only a rather incomplete washing, manually or automatically in a dishwasher, because the innermost filtering baffles of the filter can only be reached with some difficulty by detergents; on the other hand, the monolithic construction of the filter does not allow the user to ascertain the measure of cleanliness actually achieved after washing.
  • aluminium which constitutes in particular the construction material of the inner filtering baffles, can be attacked by corrosion by certain acids developed from frying vapours produced when using some cooking oils and fats, especially those of animal origin.
  • filters of the aforesaid kind are characterised by a certain structural complexity which requires several operations, necessarily entailing a certain use of manpower and a certain cost of the operations.
  • the frame that holds together filtering baffles in a stack is obtained by means of a C-section aluminium bar that is conveniently cut to measure, bent and riveted to close it.
  • the handle made of two plastic parts, coupled and screwed on to each other, is the provided with an internal metallic actuation element, contrasted by steel springs, and associated to the structure of the filter.
  • the aim of the present invention is to overcome the drawbacks of prior art filters with a filter that is can be totally disassembled, cannot be attacked by corrosive agents, can be washed without any problems and, once its working life is ended, can be totally recycled in the most economical manner possible, with respect to its constituting materials.
  • a filter for aspirating kitchen hoods provided with at least a filtering baffle, characterised in that it comprises two distinct half-shells having walls and edges, contouring the walls and the filtering baffle, that are monolithic with the walls themselves, at least one of said half-shells bearing, for latching to the structure of the hood, at least a fixed appendage and at least a movable appendage, located in correspondence with a contour segment of said half-shall opposite to the one involved by said fixed appendage, said one or each movable appendage being mounted in guiding fashion and locked by elastic reaction means in such a way as to project relative to the edge of a said half-shell and to concur in the removable latching of the filter to the hood structure; said half-shells being able to be associated to each other in removable fashion with mutual opposition of said walls and with the interposition of at least one said filtering baffle.
  • Figure 1 globally shows a filter for aspirating kitchen hoods essentially comprising two independent half-shells respectively indicated with the reference numbers 2 and 3, one or more filtering baffles 11; and a handle indicated as 12.
  • a first half-shell 2, having quadrilateral contour includes a planar wall indicated as 4, which is monolithically integrated with an "L" shaped edge 6, which externally contours the periphery of the half-shell 2, and internally thereto, also the wall 4 itself comprising in particular a wall abutment 15.
  • the wall 4 is also traversed by an opening 13 so shaped and dimensioned as to be accessible by a person's fingers.
  • a part of the contour of the opening 13 is surrounded by an edge 18 bearing wall segments which are parallel an opposite to corresponding wall segments of the edge 6 of the half-shell 2, including among them also the wall abutment 15.
  • the first half-shell 2 B better visible in Figure 2 B bears two fixed appendages indicated as 8, obtained in its own structure in correspondence with a side of the contour opposite the one involved by the wall 4.
  • the appendages 8 B visible in detail in Figure 4 also have a planar surface, parallel to the one of the wall 4, are borne in projection by the contour of the half-shell 2 and are oriented towards the exterior of the contour thereof.
  • the half-shell 2 bears a series of regularly distributed teeth 16 which, as Figure 5 shows, project from the edge 6 of the half-shell 2 and are oriented towards the interior of the half-shell 2 itself.
  • the second half-shell 3 has a similar structure to that of the first half-shell 2.
  • it is also provided with a quadrilateral, "L" shaped edge 7, structurally integrated and monolithic with a planar wall 5.
  • the edge 7 is provided with a series of seats 17 regularly distributed along the contour of the half-shell 3, visible in greater detail in Figure 6.
  • the filtering baffle 11 is constituted by one or more micro-holed panels and it has its own contour 19 shaped in conformity with the inner contour of the half-shells 2 and 3 and with the outer contour of the walls 4 and 5 of the firs and of the second half-shell 2 and 3.
  • Figure 7 shows the handle 12. It has substantially "C” shaped plan form and it is provided with end appendages 9 which are monolithic with the body of the handle 12 and able to be inserted into correspondingly shaped openings 20, obtained on the contour segment of the first half-shell 3 that is adjacent to the wall 4.
  • the handle 12 is also provided with two elastically deformable blades 12 obtained on a segment of its own contour and positioned on a side opposite the one bearing the end appendages 9.
  • the handle 12 is housed in the first half-shell 2 above the wall 4, with its own appendages 9 aligned with the openings 20 of the segment of the edge 6 adjacent to the wall 4 and with the elastically deformable blades 14 in contrast with the wall abutment 15 of the contour.
  • the handle 12 By the superposition of the second half-shell 3 with the first half-shell 2, with corresponding superposition of the respective walls 5 and 4, the handle 12 remains completely confined in a sort of box-like container that also incorporates a guide 10 for the translation of the handle 12 upon its manual actuation effected through the opening 13 in opposition to the reaction provided by the elastic blades 14.
  • connection itself is accomplished by means of the snap-on coupling between the teeth 16 and the complementary seats 17 of the two half-shells 2 and 3.
  • connection system allows the monolithic connection of all elements comprising the filter 1, as is necessary during normal use of the filter 1, and they simultaneously allow the capability to disassemble the filter 1 easily and completely when it is necessary to proceed with its internal inspection and/or cleaning.
  • all the component parts of the filter 1 are made of a single material and in particular a plastic material of suitable nature to assure, for instance, heat resistance, self-extinguishing ability, lack of vulnerability to acid and detergent attacks, to the advantage of a possible and rapid cleanability and of total hygiene are also added the advantages of a facilitated and economical disposal of the filter 1 as waste at the end of the working life of the filter 1 itself.
  • the invention therefore fully achieves the objectives correlated to the aforementioned aims and, in comparison to the prior art in the industry, it also has considerable economic advantages both in terms of its technological feasibility and relatively lesser demand for manpower, and in terms of the ability to recover the material constituting it at the time of the disposal and scrapping of the product.
