Definitions

  • the object of the present invention is a recessed air extractor, of the type comprising: a support housing of insulating material; an impeller equipped with vanes acting as axial fan; an electric motor; and an electronic circuit.
  • the invention aims to overcome these drawbacks.
  • This purpose is achieved by means of an extractor of the type referred to at the beginning, which is characterized in that said support-housing comprises: a cylindrical zone; and a laminar zone arranged jointly in substantial orthogonality to the axis of said cylindrical zone; said cylindrical zone having a cavity partially occupied by a coaxial cylindrical body in which said impeller, said electromotor and said electronic circuit are housed; said cylindrical zone and said cylindrical body being joined by radial arms; and, between said cylindrical zone and said cylindrical body, there is a passage surrounding said cylindrical body; and said laminar zone presenting at its periphery, an elastic section that tends to exceed said periphery and which is apt to be removably anchored in a notch of a lateral edge of a front cover, which is in the form of a small bowl and is provided with a window.
  • the extractor object of the invention has several advantages with respect to the models that are currently marketed in the market, and these advantages are based on its low profile, this small thickness of the lid allows it to be installed on a ceiling or window wall as needed .
  • Fig. 1 is an exploded front perspective view of the extractor object of the present invention.
  • Fig. 2 is a diametral section of the extractor according to Fig. 1, conveniently assembled.
  • Fig. 3 is a diametral section of the same extractor, also representing elements related to its adaptation to a glass of any standard thickness.
  • Fig. 4 is an exploded front perspective view of the housing-support of the extractor and the cover, showing the assembly system schematically.
  • the extractor apparatus object of the invention comprises, first of all, a housing-support which is preferably molded in one piece from an appropriate plastic material.
  • This support housing is formed by a cylindrical zone 1, and a laminar zone 2, whose orientation is perpendicular to the ideal axis of the cylindrical zone; preferably it is square in shape although its sides are slightly concave ..
  • the cylindrical zone 1 is intended for housing the assembly formed by the impeller 6 provided with vanes, which acts as an axial fan, the electric motor 5 and the electronic circuit 7, useful for different applications. Inside said cylindrical zone 1 there is also a recess that is partially occupied by a cylindrical body 3, preferably molded in one piece with the assembly, located in coaxial position with respect to the cylindrical zone 1; Therefore, it can be seen that between the cylindrical zone 1 and the cylindrical body 3, a step remains.
  • This cylindrical body 3 is connected by means of radial arms 4 with the cylindrical zone 1.
  • the electric motor 5 is housed, almost entirely, inside the cylindrical body 3 and the impeller 6 is directly interlocked on the axis of the electric motor 5 It is preferred that the impeller 6 be molded from a single piece of an appropriate plastic material to partially cover the electric motor; This eliminates any possibility of establishing contact with areas of the extractor that may be under electrical voltage, even using the test caliber required in the tests dictated by the electrical safety standard.
  • the cylindrical body 3 consists of two inverted housings, one for the aforementioned electric motor and another in the central part to accommodate the different electronic circuits, such as the timer circuit and the circuit 7 equipped with a humidity sensor ( Fig. 1).
  • this housing allows to fix a standardized connection strip in the case of a standard extractor, or to fix the electronic circuits in a fast and safe way keeping them held by flexible nails inside the housing, which provides the advantage of allowing all the connections to be made in its installation without taking up space in the outside area and allowing the use of an exaggeratedly flat lid 8, where it brings an innovation in the size of the extractors marketed until now, allowing to embed almost entirely within the tubes of driving, in holes or other housings made in walls, windows or ceilings for this use.
  • Each space also comprises a substantially prismatic part 32 pierced by the screw 9; this piece 32 is fitted without the possibility of turning in the space mentioned; in this way, by turning the screw 11, the piece 32 moves towards the outer partition, and consequently causes the tilting of the nail 9 towards the outside of the cylindrical body 3, whereby its free ends protrude from the space and can swell in a body that surrounds the cylindrical zone 1, the nails 9 being anchored in the walls where it should be installed, fixing the extractor in a fast and clean way.
  • the radial arms have been designed with a flat and thin shape, so that they act modestly as fixed air flow guidelines, taking full advantage of the circular section for the passage of said flow, but being able to execute them with other forms and sections.
  • a central column 12 can be seen, to screw the protective cover 13, preferably molded in one piece, which can close the housing of the electronic circuitry; preferably it is round, but it can adopt other configurations, with arms arranged at 180 ° in order to adapt to the channels made in the radial arms for the passage of the cables and to be able to position the cover 13 safely, in case it is considered Convenient, small grooves 14 can be made allowing moisture to pass through for detection without violating any standard test. It also incorporates a drill 15, in the case of incorporating a humidity sensor in order to show a light emitting diode (led) for signaling operation.
  • a front cover 8 can fit under pressure and be fixed on the front face of the support housing; This can be done, for example, by means of a non-return anchoring device 31, which is only unlocked with the aid of a screwdriver tip.
  • Said preferably slightly convex or domed cover provided with a large central window 17, which constitutes the intake or air inlet opening of the extractor, which is covered by a grid 18, preferably molded in one piece with the assembly, framed by the inside of the window 17 by a flange 19 (Fig.
  • the output of the conductors corresponding to the power circuit of the apparatus can be carried out through the weakened opening 20 provided for this purpose in the laminar zone or flat fin 2, or it can also be carried out laterally through the front cover 8, provided with a Notch 21 on its side wall.
  • the cylindrical zone 1 there are two grooves of square shape for the anchoring of a first ring 22, which in turn is provided with nails for fixing and drills. that cross the thickness of the first ring 22 to incorporate two semicircular fins 24, whose function is intended to block the passage of the return air, with the help of two low pressure springs, inserted in the axis of rotation of the fins, giving the only possibility of the passage of air towards the outside.

It is for all the reasons mentioned that in both cases the distance is compensated with the compensation frame 28 that, when fitted, the desired height can be constructed.
