Definitions

  • the present invention concerns a fume and vapour removal setup of the type comprising a succession of pipe lengths connected with each other in order to form the general structure of a fume and vapour piping to be connected to an exhausting unit such as a fume and vapour hood or exhaust device for cooking ranges and the like (bathrooms, enclosures to be ventilated, etc.), the interior of said exhauster being generally divided in two chambers which are namely a suction lower one and a delivery upper one between which are arranged at least a fan or turbine driven by an electromotor and filtering means of diverse nature, said delivery chamber ending in a duct to which said fume and vapour piping is connected.
  • an exhausting unit such as a fume and vapour hood or exhaust device for cooking ranges and the like (bathrooms, enclosures to be ventilated, etc.)
  • the interior of said exhauster being generally divided in two chambers which are namely a suction lower one and a delivery upper one between which are arranged at least a fan or
  • DE-A-2918058 and US-A-3.889.581 both refer to ducting pipes for fumes and vapour exhaust consisting of flattened lengths with one of its wall flat apt to rest on a floor, said flattened shape allowing to conceal and so making difficult to perceive said ducting pipes from an observer placed at the kitchen when the ducting pipes are installed on the upper part of cupboards of the said kitchen adjacent a rear wall.
  • a guard grating is arranged in order to prevent the penetration into the piping of animals or insects which could clog or damage it, said grating generally comprising a shutter consisting of rotatably hinged leaves made of a light material which are lowered by gravity thereby closing the passage, and which have to be raised by the fluid impelled by the fume and vapour hood or exhaust device.
  • said grating determines in practice an obstacle which adds one more difficulty to the free removal of said fumes and vapours through said outlet or exhaust.
  • the invention refers precisely to said fume and vapour pipings for concealed lying which as has been said above have been so far built with a flattened shape of generally rectangular cross-section and with rounded edges, and its aim is to obviate the above-mentioned drawbacks, and more specifically to achieve a good conduction of the fumes and/or vapours in the bends thereby facilitating the redirecting of the flow and avoiding pressuree-surge effects and stagnations and in general providing a proper circulation of the sucked flow all throughout the ducting which has besides a configuration that facilitates its installation.
  • the piping or ducting as per the invention thus allows to use to full advantage the performance characteristics of the fume removal hood.
  • the outlet or delivery pipe of the fume and vapour hood or exhauster has a diameter of about 12 cm and admitting all along the ducting a reduction of the passage cross-section of 15% with respect to that of said outlet pipe, the proposed duct will perform properly in connection with fume and vapour hoods or exhaust devices having an output of up to 6,50 m 3 /h.
  • the invention is characterized in that the passage cross-section of the different pipe lengths (including the bends) (10), (11), (12), (13), (14) and (15) forming the fume and vapour piping identified in general with numeral (16) remains more or less constant and is equivalent to that of pipe (17) which generally has a circular shape and is the outlet or delivery pipe of a fume and vapour hood (18), and all pipe lengths (10), (11), (12), (13), (14) and (15) have a common cross-section profile.
  • pipe (17) which generally has a circular shape and is the outlet or delivery pipe of a fume and vapour hood (18)
  • all pipe lengths (10), (11), (12), (13), (14) and (15) have a common cross-section profile.
  • switch (19) which activates the operation of the fume and vapour hood or exhauster (18) will also actuate a device of conventional type (such as for example an electromagnet, not shown) associated to a terminal (20) coupled with end tubular element (15) of the fume and vapour piping (16), said actuation opening a grating which is conventionally included in the opening of said terminal (20) thereby determining a free outlet or exhaust for the circulating air, fume and vapour flow.
  • a device of conventional type such as for example an electromagnet, not shown
  • An essential characteristic of the invention is besides the particular configuration and structure of the different pipe lengths (10), (11), (12), (13), (14) and (15) employed which consist in sensibly flattened elements which are apt to pass unnoticed and one of whose walls is flat in order to be in a position to rest on a flat base (top surface of a kitchen cabinet in the most typical case), at least another of their walls being bulged towards the outside and being essentially the one that forms the top of the respective element.
  • pieces (11) and (13) shown in perspective view in Figs. 5 and 6 have in all cases a flat wall (21) and another convexly curved wall (22) which is bulged towards the outside and is in this case directly opposite the former one.
  • Bend (10) which is the first pipe length connected to outlet or delivery pipe (17) of the fume and vapour hood or exhaust device, and which is shown in Fig. 4, comprises a tubular body describing a quarter bend which having a first end (10a) of circular cross-section matching the cross-section of said outlet pipe (17) of fume and vapour hood (18) changes its shape progressively towards the other end till forming a length (10b) of essentially rectangular cross-section with rounded edges with a top wall bulging towards the outside and with a flat bottom wall connecting in a descending ramp and curved profile with the lateral wall of length (10a).
  • the last pipe length (15) of the fume and vapour piping shown in Fig. 7, comprises a tubular straight body which having a first end (15a) of essentially rectangular cross-section with rounded edges and with a top wall bulging towards the outside to connect with a straight or bent length of equivalent cross-section of piping (16) changes its shape progressively towards the other end (15b) till forming a cylindrical length which is apt to be connected to terminal (20).
  • Fig. 8 shows an element for connecting pipe lengths in order to adapt their length, said element consisting of a ring (30) whose profile matches that of pieces (10), (11), (12), (13), (14) and (15) and whose cross-section is slightly bigger than that of said pieces, said ring having a central inner rib (31) which is apt to receive in a plug-in connection through both ring openings the ends of two ducts (10), (11), (12), (13), (14) or (15).
  • Fig. 2 The profile of the conventional connection between pipe lengths has been illustrated in Fig. 2 in the detail that shows the connection of pieces (12) and (13).
  • Figs. 9a, 9b and 9c show the cross-sectional shape of several pipe lengths (23), (24), (25) which are apt to be employed to form the fume and vapour removal setup of the invention, and which differ only in the way to form the duct top or vault and in the number of faces bulging towards the outside.
  • Fig. 3 shows more in detail terminal (20) connected to end pipe length (15) of the fume and vapour piping, said terminal being provided with a grating of horizontal leaves (26) which are made of a light material, are rotatably hinged at their upper part and close by gravity a central opening of said terminal (20) which is coaxial with the passage of said pipe (15).
  • an electrically operated device such as an electromagnet (not shown) has been provided which moves levers or riders (27) which are rotatably pin-jointed with a first stationary post (28) and are as well linked to a bar (29) attached to the rod of said magnet.
  • a spring counteracts said magnet thereby allowing the leaves to return to an inactive position in case of a power shutdown or trouble, so that even if said magnet does not actuate properly the leaves regain their closed position in any case thereby closing the outlet.
