Definitions

  • the present invention refers to an air extractor of the type comprising a cylindrical configuration support casing finished off on the suction side with a perimetral rim on which a front cover is arranged, and housing an electromotor, a coaxial housing for said electromotor, a fan and regulation and control means.
  • the object of the invention is based on the design of the support casing and the housings in which its different components are installed, allowing the installation of an extractible front cover, all this complying with the corresponding safety standards.
  • These safety means are generally materialized in a protective cover including a grid, preventing contact with the rotating blades.
  • the safety means consist of the incorporation of a front cover with a grid for the passage of air, closed enough so as to prevent passage of the user's fingers.
  • the air extractor proposed by the invention solves the drawbacks set forth above since it is provided with a design facilitating its maintenance and conservation, since it permits removing the front cover in a practical and simple manner, with no risk for the user, all this complying with the corresponding safety standards.
  • the air extractor belongs to the type that comprises a cylindrical configuration support casing, finished off on the suction side with a perimetral rim on which a front cover is arranged, and housing an electromotor, a coaxial housing for said electromotor, a fan and regulation and control means.
  • This type further comprises a housing for the electromotor composed of a cup located in the rear part of the cylindrical area of the casing, it having been provided that said cup be held inside the cylindrical area of the casing by means of a plurality of arcuate radial projections, in vane form, preventing access to moving parts.
  • the anchoring elements are composed of a series of lugs projecting from the inner surface of the front cover, in correspondence with respective holes made on the perimetral rim of the support casing.
  • the ends of the lugs are provided with a magnetized base fixed on respective metal washers arranged at the bottom of the holes made in the perimetral rim of the support casing.
  • Another aspect of the invention is based on the arrangement of a housing in the perimetral rim of the support casing, which houses the connection, regulation and control elements of the electromotor, which housing is closed with a hinged cover integrated on the outer design of the perimetral rim of the casing, which is aided by a smooth opening spring.
  • the air extractor proposed by the invention is composed of a cylindrical configuration support casing (1), finished off on the suction side with a perimetral rim (2).
  • Said casing (1) supports the different components integrating the extractor, such as the electromotor (3), the fan (4), as well as the corresponding connection, regulation and control elements housed in a housing (5) located on the perimetral rim (2), which is closed by a hinged cover (6) integrated on the outer design of the perimetral rim (2) and aided by a smooth opening spring (7).
  • the housing of the electromotor (3) which is composed of a cup (8) coaxially located on the rear part of the cylindrical area of the casing (1) and held by means of a plurality of arcuate radial projections (9), in vane form, as can be seen in figure 6.
  • a cup (8) coaxially located on the rear part of the cylindrical area of the casing (1) and held by means of a plurality of arcuate radial projections (9), in vane form, as can be seen in figure 6.
  • the arrangement of the plurality of arcuate radial projections (9) provides the safety necessary for preventing access to the moving parts, which allows installation of an extractible and easily removable front cover (10) arranged in correspondence with the perimetral suction opening of the casing (1), providing a pleasant appearance.
  • Said cover (10) is provided with anchoring elements allowing its fixing and separation with regard to the perimetral rim (2) composed of a series of lugs (11) projecting from the inner surface of the cover (10) in correspondence with respective holes (12) on the perimetral rim (2).
  • the diameter of said lugs (11) is slightly greater than the diameter of the holes (12) for carrying out fixing thereof.
  • the ends of the lugs (11) are provided with a magnetized base (13) fixed on respective metal washers (14) located at the bottom of the holes (12).
  • the user can withdraw the front cover (10) to carry out cleaning of the extractor with no hazard whatsoever.
  • the electromotor (3) is covered by an approximately semi-oval shaped dome (15) in correspondence with the central hole (16) provided on the front cover (10).
