Definitions

  • the present invention relates to an air intake vent to be mounted on peripheral, or in any case external, walls of buildings, with the purpose of ensuring a correct supply of combustion air to lighting sources installed inside the premises, in particular in connection with the combustion of gases in boilers of independent heating systems.
  • vents intended to supply external air into the premises where a burner is operational should be installed in the bottom part of the external wall, close to the ground.
  • vents having both a circular cross-section and a rectangular or square cross-section and consisting of a vaned external grill, a meshwork located immediately behind the grill in order to prevent the entry of small animals or insects, a tubular conduit with a constant cross-section complying with the local regulations, and an internal grill which is also usually vaned.
  • vents have the drawback that they give rise to bothersome air currents in the vicinity of the grill inside the dwelling, such that uncomfortable and even untolerable living conditions occur in the presence of wind, owing to the gusts of cold air which flow into the premises where the grill is installed.
  • the object of the present invention is to provide an air intake vent which allows correct ventilation of the premises where a burner is installed and at the same time eliminates, or greatly lessens, the discomfort resulting from gusts of air entering the dwelling, in particular during windy weather conditions.
  • a further object is to provide a vent which can be easily installed and at the same time is operationally reliable since it ensures a continuity of air flow while complying with the minimum cross-sections suitable for the capacity of the burner installed inside.
  • Fig. 1 shows a longitudinally sectioned view of a vent provided in accordance with the invention
  • Fig. 2 shows a front view of one of the base elements forming the central part of the vent
  • Fig. 3 shows a cross-sectional view along the plane indicated by III-III in Figure 2
  • Fig. 4 shows a partially sectioned axonometric view, observed from the external environment side.
  • 1 denotes a known external grill provided with vaning and 8 a known internal inlet grill.
  • duct 2 denotes a duct forming the central part of the vent which, in the case exemplified, has a circular shape; the duct 2 connects the external environment to an internal environment where, for example, a burner of a boiler operates.
  • 3 denotes a base element of the vent consisting of a tubular body 4 provided at the ends with telescopic-type connections 6, 6' and an inclined double vaning 5, 5' oriented in the direction of the air flow indicated by the arrows in Fig. 1.
  • the double vaning comprises at least one first vane 5, which is located inside the duct 2 and which extends from the periphery towards the centre of the duct 2 itself.
  • the first vane 5 is inclined with respect to the longitudinal axis of the duct 2 so that its surface directed towards the external enviroment forms an acute angle with the direction of the flow along the duct 2 from the external environment towards the internal environment.
  • the double vaning also comprises a second vane 5' which is arranged between the first vane 5 and the internal environment at a predetermined distance from the first vane 5 and is located with an inclination substantially identical to that of the first vane 5.
  • the aperture 9 denotes a wide aperture or window formed on the first vane 5 in the vicinity of the wall of the tubular body 4.
  • the aperture 9 has an elongated shape with an arrangement parallel to the end edge of the first vane 5.
  • the second vane 5' is located so as to face the aperture 9 at a distance d.
  • the aperture 9 is formed and arranged so that its projected path along the longitudinal axis of the duct 2 is intercepted entirely by the second vane 5'.
  • the externally directed surface of the first vane 5 forms an angle of 60° with the direction of the flow along the duct from the external environment towards the internal environment; this value may, moreover, normally vary from a minimum of 30° to a maximum of 70°.
  • the value of the distance d is usually equal to 1/8th of the internal diameter of the tubular body 4; the value of the distance d may moreover usually vary within a range of 1/12th to 1/4er of the value of this internal diameter. It is moreover envisaged that the first vane 5 should extend as far as the halfway point of the internal channel delimited by the tubular body 4, terminating in a thin bent-back edge 10 arranged along an internal diameter of the aforementioned channel.
  • two base elements 3, 3' of the vent are provided, said elements being identical to one another and being arranged in succession with one another.
  • the two elements 3, 3' are rotated through 180° with respect to one another about the common longitudinal axis.
  • 7, 7' denotes two male and female locating means of the interlocking type designed to ensure correct connection of an element 3 with a successive identical element 3' rotated through 180° with respect to the first one.
  • the elements 3, 3' are joined together by telescopic-type connections 6, 6' and are correctly positionned with respect to one another by the interlocking locating means 7, 7'.
  • the vanes 5, 5' of the base element 3 occupy the top half of the duct 2, while the vanes 5, 5 ' of the other base element 3' occupy the bottom half thereof.
  • an element 3 is installed in the central section of the duct 2, together with, in succession, a second identical element 3' in a position rotated by 180° with respect to the first element.
  • the vent is completed by the fitting of known end grills 1, 8.
  • vents with a circular cross-section Although shown in the example illustrated as a vent with a circular cross-section, numerous variations of the invention are possible, for example vents with a square or rectangular cross-section.
