Definitions

  • the invention relates to a mixed ventilation device for a dwelling.
  • Mixed ventilation devices for dwellings comprising a duct having an air inlet opening situated in the dwelling and an air outlet opening situated outside the dwelling, in particular the roof, the ventilation air passing from the interior to the exterior of the dwelling via the ventilation device.
  • Such ventilation devices are for example associated with kitchens or bathrooms or more generally with the living rooms of a dwelling. It was found, however, that in some cases natural ventilation was not sufficient.
  • a vacuum cleaner for gaseous fluid in particular exhaust gas or smoke
  • having an air passage in the form of a venturi see documents FR-A-2 374 591, FR-A -2,474,651, FR-A-2,438,795 and EP-A-0,079,256).
  • the structure of the ventilation device according to the invention (with a ventilator aspirating in an internal central space, a free annular space, devoid of ventilator, these two spaces communicating with the interior of a section is also completely different from that of these documents.
  • a chimney comprising three concentric conduits extending between the two ends of the chimney, defining three different gas streams totally and permanently separated from each other.
  • the invention aims to provide a mixed ventilation device for a home which can both operate in natural ventilation and, when desired, in forced ventilation, forced ventilation then intervening with complementary natural ventilation by induction. This problem is totally different from those solved by the documents cited above.
  • the invention provides a mixed ventilation device of the type mentioned above in which the duct comprises a main outlet section substantially adapted to natural ventilation, a short inlet section with an enlarged section, a frustoconical section for connecting the inlet section to the outlet section, a closed, solid, substantially cylindrical or prismatic side wall housed in the entry section, a suction fan housed in the internal central space defined by the closed side wall, the closed side wall defining with the inlet section a free internal annular space, the internal central space and the internal annular space being in communication with the interior of the section frustoconical and the latter with the interior of the main section, means for selectively controlling the start and stop of the suction fan, so that when the suction fan stops, the ventilation air passes substantially from the internal annular space and that when the suction fan is operating the ventilation air passes on the one hand through the internal central space thanks to the operating suction fan and, on the other hand, through the internal annular space where it is driven by the air passing through the internal central space.
  • the device can also include a static vacuum cleaner mounted in the outlet opening of the duct.
  • the invention relates to a mixed ventilation device for a dwelling.
  • the device comprises a duct 1, in particular metallic, continuous, closed laterally, having an air inlet opening 2, notably lower, located in the dwelling 3 and an air outlet opening, notably upper, located at the exterior 5 of the dwelling 3.
  • the air outlet opening 4 is placed in particular on the roof 6 of the dwelling 3.
  • the ventilation device operates so that the ventilation air passes from the interior to the exterior of the dwelling 3 via the device, that is to say through the duct 1 from its inlet opening 2 to its outlet opening 4 from which it is discharged into the atmosphere.
  • the duct 1 comprises a main outlet section 7 substantially adapted to ventilation natural, occupying most of the duct 1.
  • This main outlet section 7 is of a type known per se in the case of natural ventilation.
  • the duct 1 also includes a short inlet section 8 which is of enlarged section relative to the main outlet section 7.
  • a frustoconical section 9 for connection comes to connect the inlet section 8 to the main outlet section 7.
  • the frustoconical section 9 therefore comprises, for this purpose, a large base 32 adjoining the inlet section 8 and a small base 33 adjoining the main outlet section 7.
  • the device also comprises a closed and solid side wall 10 substantially cylindrical or prismatic, housed in the inlet section 8.
  • This wall defines an internal central space 12 in which is housed a suction fan 11 with selective operation, that is to say say that depending on the command that is make the fan 11 works or does not work.
  • the fan is of the suction type, that is to say it is arranged in the internal central space 12 so as to cause the circulation of air in the direction going from the inlet opening 2 to the opening outlet 4.
  • the side wall 10 defines with the inlet section 8 which is placed radially opposite but spaced outwardly an internal annular space 13 of general shape of a cylindrical or prismatic ring while the central space internal 12 itself has a generally cylindrical or prismatic shape.
  • the internal central space 12 and the internal annular space 13 are separated from each other in line with the wall 10 but communicate to form a single common space inside the frustoconical section 9.
  • the interior 14 is in communication with the interior 15 of the main section 7 so as to allow the circulation of ventilation air from the inlet opening 2 to the outlet opening 4.
  • the device also includes means 16 for selectively controlling the start and stop of the suction fan 11. When the suction fan 11 is stopped, the ventilation air passes substantially through the internal annular space 13 according to the arrow Fn. This passage is free, without hindrance. When the suction fan 11 is operating, the ventilation air partly passes through the internal central space 12 thanks to the suction fan 11 in operation, according to the arrow Ff and also, partly, through the internal annular space 13, according to arrow Fn.
  • a static vacuum cleaner 17 is mounted in the outlet opening 4 of the duct 1.
  • This static vacuum cleaner 17 is preferably of the venturi type 18.
  • the static vacuum cleaner 17 is of the type comprising a lower element 19 comprising at least one upper part 20 of frustoconical shape with small base 21, an upper element 22 comprising a part upper 23 and a lower part 24 both of conical shape, opposite and joined by their bases 25.
  • Securing spacers 26 rigidly connect the two elements 19, 22 ensuring between them the existence of the passage 18 defined by the upper part 20 of the lower element 19 and the lower part 24 of the upper element 22.
  • the passage 18 has an axial section in the general form of a venturi.
  • Such a vacuum cleaner is described in the state of the art mentioned in the preamble, state of the art to which one can refer.
  • the present invention does not relate to the static vacuum cleaner 17 per se but to the functional association of the static vacuum cleaner 17 with the ventilation device as described above.
  • the side wall 10, the inlet section 8, the frustoconical section 9 and the main section 7 are preferably coaxial with an axis 27 which is preferably vertical.
  • the main outlet section 7 may include one or more elbows.
  • a grid 28 which adjoins the side wall closed 10 by its internal end 29.
  • This grid 28 aims on the one hand to prevent the entry, into the duct 1, of elements exogenous and also to prevent unwanted access to the fan 11 and finally to define separate air inlet veins for the internal central space 12 and the internal annular space 13 by avoiding for example that the fan 11 has the effect of sucking air from the internal annular space.
  • the axial length 1 (counted along the axis 27) of the closed side wall 10 is at most equal to that L of the inlet section 8. It follows that the internal end 30 of the closed side wall 10 opposite the outer end 29 is placed radially opposite the inlet section 8 since the free end 34 of the inlet section 8 is also adjacent to the grid 28.
  • the opening angle ⁇ of the frustoconical section 9 is for example of the order of approximately 90 ° to 120 °. However, this angle can be adapted to the different situations and specificities of the device.
  • the device which has just been described works optimally with certain dimensional ratios or certain orders of magnitude of dimensional ratio.
  • the area S3 of the cross section of the main section 7 is substantially equal to the area S4 of the cross section of the annular space 13.
  • the area S1 of the cross section of the central space internal 12 is smaller, notably much smaller than the area S4 of the cross section of the internal annular space 13.
  • S1 is of the order of a third of S4.
  • the area S5 of the passage section between the internal end 30 of the closed side wall 10 and the frustoconical section 9 is at least equal to the area S3 of the cross section of the main section 7.
  • the fan 11 normally occupies, radially and in operation, almost all of the transverse cross section S1 of the internal central space 11, that is to say that the free end of its blades comes in close proximity to the wall 10 .
  • the control means 16 are manually operated by a control button 31 or automatically operated by automatic means provided for this purpose 32 and this in response to a certain control instruction.
  • the control means generating a control signal are for example a clock, a pressure switch or a hygrostat. These control means are adapted to take account of a parameter determining the necessity or the usefulness of using the fan 11, respectively the superfluous nature of this operation.
  • the fan 11 can operate at certain times and not at others, hence the advantage of control means such as a clock.
  • the pressure existing inside dwelling 3 can be a valid parameter. Finally, it can be the degree of humidity prevailing in the home.
  • the inlet section 8 and the outlet section 7 may have a diameter of around 2 and 1.5 times the diameter of the closed side wall 10, respectively.
  • the side wall 10 can have a diameter of the order of 10 cm.
  • the duct 1 preferably has a circular shape but can also have a square, polygonal or other shape.
  • the internal annular space 13 is free, that is to say that the passage of air through it is not hindered in any way, since this space is functionally arranged for natural ventilation. . Consequently, the internal space 13 is devoid of fan, valve, etc.
  • the opening 2 is common to the two spaces 12, 13, the two ends 29, 34 both being adjacent to the grid 28.
  • This structure allows direct air intake by each of the spaces 12, 13.
