Definitions

  • the invention relates to a device for discharging burnt gases and for admitting fresh air of the type described in the first part of claim 1.
  • This arrangement is advantageous because it makes it possible to connect the device to a micro-cup placed outside the wall of the housing by drilling in the latter only a simple round hole of small diameter.
  • microvalve also with a coaxial structure is simpler to manufacture and has a minimum size.
  • This adjustable elbow is generally mounted on the outlet of the exhaust gas exhaust fan itself fixed to the exhaust hood, fresh air being admitted outside the hood and recycled to the burners inside of the waterproof enclosure. Or the elbow is mounted directly on the hood and the exhaust tube carries the exhaust fan.
  • the fan is generally with an inclined axis, which is detrimental to its proper functioning in a hot atmosphere.
  • evacuation devices essentially consisting of a hood having an L-shaped profile, a collecting chamber disposed immediately above the heating body of the device, the upper cover of which is slightly inclined on the horizontal, of a vertical exhaust chimney surmounting said cover and of an air distributor box according to the patents FR-A-2 113 554, US-A-2 617 371 and GB-A-1 307 291 .
  • the exhaust device according to the invention facilitates the mounting of the exhaust fan and promotes the admission of fresh air, to be compatible with the use of an adjustable connection elbow, and this to take account of modern requirements. such devices in the field of simplicity and compactness.
  • the device is characterized by the fact that the air distribution box of small thickness and of parallelepiped shape is fixed horizontally on the top of said chimney, that it essentially closes the entire upper face of the sealed chamber, equivalent to the base surface of the hood, thus creating an interior space in which the exhaust fan is arranged, the outlet pipe of which passes through the distributor housing and which is provided on its lower wall with air passage openings .
  • the exhaust fan and its drive motor with a horizontal axis is mounted on a vertical wall of the chimney, covering an orifice provided on the latter.
  • the outlet pipe which passes through the air distributor box is fitted onto the inner duct of the orientable elbow, the fan thus advantageously being housed in the hollow space between the cover of the collecting chamber, the chimney and the distributor air, its axis being horizontal which improves its longevity.
  • the adjustable gas outlet elbow can be oriented in all directions, which is advantageous in particular for the renovation of old premises.
  • This hood is designated as a whole by the reference 1, it covers the fin block 2 which constitutes the heating body of the device. It has an L-shaped profile, the lower rectangular part of which is fixed to the fin block, forms the collecting chamber 10, the upper cover 11 of which is slightly inclined to the horizontal. A vertical exhaust chimney 12 extends upwards said collecting chamber.
  • the side wall is further closed at its upper part by a horizontal plate 14.
  • On the latter is fixed an air distributor housing 15 of parallelepiped shape and reduced thickness which, in addition, has an area equivalent to the base surface of the hood.
  • the upper face of this box is pierced with an orifice 16 for the evacuation of the burnt gases and the admission of fresh air.
  • This orifice is capped with an orientable connection elbow 3, known per se, whose inner duct 4 of smaller diameter passes through the entire housing 15 in leaktight manner to fit onto the outlet tube of the exhaust fan 5.
  • the external conduit 6 of the orientable elbow covers the whole of the orifice 16 so that the fresh air admitted by the annular space between the conduits 4 and 6 enters the distributor box 5.
  • orifices 17 are provided on the lower wall of the housing 15 for the passage of combustion air towards the burners, outside the hood 1. On these orifices 17 can also be added small air intake tubes in particular for monitoring the flow rate and device security.
  • the exhaust fan 5 is fixed to the side wall of the chimney 12 above the orifice 13.
  • the motor 7 for driving the turbine 8 of the said fan is itself mounted on the hood of the exhaust fan 5. It thus occupies the hollow space available between the cover 11 of the collecting chamber 10, the chimney 12 and the air distributor housing 15. It has a horizontal axis which makes it easily accessible and removable and guarantees it good operation.
  • the assembly described above, which constitutes the hood and the air distributor box is fixed to the backrest 9 of the device against which is intended to apply in a sealed manner the outer cover 20.
  • air 15 On the outer face of the distributor box d air 15 is provided for this purpose a bar 18 which crowns the adjustable elbow 3 and serves as a support for a seal 19 against which the cover 20 is applied.
  • the upper face of the latter is obviously notched and shaped to correspond to the profile of the bar.
  • the fan 5 extracts towards the duct 4 the burnt gases collected by the hood 1, by means of the orifice 13 provided on the chimney 12.
  • the distribution of the suction of the burnt gases over the whole of the fin block 3 is facilitated by the installation, - inside of the collecting chamber 10 -, of at least one deflector flap 21 inclined on the horizontal.
  • the extraction of the combustion gases leads to the suction of fresh air through the annular space between the tubes 4 and 6 towards the air distributor box 15.
  • the distributor box allows the distribution of the air sucked towards a plurality of orifices 17, this air continuing in a downward movement towards the burners not shown, by licking the external walls of the hood and of the heating body.
  • This arrangement has the advantage of ensuring permanent ventilation of the motor 7.
  • the exhaust fan and its motor are immediately accessible, easily removable from the hood to which they are fixed.
  • the size of the hood and the extraction system is therefore very small and goes in the direction of a search for simpler and more compact devices.
