Definitions

• the present invention relates to an air extractor of the type comprising a cylindrical housing-support finished off by the suction side by a perimeter edge, on which a front cover is arranged, and houses an electric motor, a coaxial housing for said electric motor, a fan and means of regulation and control.
• the object of the invention lies in the design of the support-housing and the housings in which its different components are installed, which allow the installation of a removable front cover, all complying with the corresponding safety standards.
• these safety means are embodied in a protective cover with an enclosed grill, which prevents contact with the rotating propeller.
• the safety means consist 'in incorporating a front cover with grid the passage of air, closed enough to prevent the passage of the user's fingers.
• the arrangement of said cover causes a great brake and a large contribution of dirt in the form of dust that added to the large amount of moisture that exists in the enclosures to be ventilated, causes an unpleasant view of the extractor shortly after being installed.
• the air extractor proposed by the invention solves the above-mentioned problem by having a design that facilitates its maintenance and conservation, by allowing the front cover to be disassembled in a practical and simple way, without any risk to the user, all This complying with the corresponding safety regulations.
• the air extractor of the type that includes a cylindrical housing-support topped by the suction side by a perimeter flange, on which a front cover is arranged, and houses an electric motor , a coaxial housing for said electric motor, a fan and regulation and control means, comprises a housing for the electric motor that is composed of a bowl located at the rear of the cylindrical zone of the housing, it being provided that said bowl is held inside the cylindrical zone of the housing by a plurality of arcuate radial projections, in the form of fins, which prevent access to the moving parts.
• said arcuate radial projections prevent accidental access to the active parts of the extractor, it allows the front cover arranged in correspondence with the perimeter opening of the housing, to have anchoring elements that allow its fixation and separation with respect to the perimeter flange of the housing-support in a fast, practical and simple way.
• the anchoring elements are composed of a series of lugs that protrude from the inner surface of the front cover, in correspondence with two holes made in the perimeter flange of the support housing.
• the ends of the lugs have a magnetized base that is fixed on metal washers arranged at the bottom of the holes made in the perimeter flange of the support housing.
• Another aspect of the invention lies in the arrangement, within the perimeter flange of the housing-support, of a housing that houses the connection, regulation and steering elements of the electric motor, whose housing is closed by an articulated cover integrated in the design outside the perimeter flange of the housing, which is assisted by a soft opening spring.
• Figure 1 shows an exploded perspective view of the exhaust fan with removable front cover made in accordance with the object of the present invention, in which all the elements that comprise it can be seen.
• Figure 2 shows a longitudinal section of the properly assembled puller.
• Figure 3 shows a plant of the air extractor, without the front cover.
• Figure 4 shows a detail of the articulated lid integrated in the perimeter flange of the housing, in the open position.
• Figure 5 shows a section along the D-D cutting lines of Figure 4, in which the arrangement of the soft opening spring can be seen.
• Figure 6 shows a section along the lines A-A of Figure 3, in which the arcuate radial projections can be seen, in the form of a fin.
• Figure 7 shows a detailed section of the anchoring of the front cover to the perimeter flange of the support housing by magnets.
• the air extractor that the invention proposes is composed of a support housing (1) of cylindrical configuration, topped by the suction side by a perimeter flange (2).
• Such housing (1) supports the different components that make up the extractor, such as the electric motor (3), the fan
• the housing of the electric motor (3) which is composed of a bowl (8) located coaxially at the back of the cylindrical area of the housing (1) and held by a plurality of arched radial projections (9), in the form of fins, as can be seen in Figure 6.
• a large part of the interior of the housing (1) can be accessed for cleaning, preventing projections radial (9) accidental access to the fan (4).
• the arrangement of the plurality of arched radial projections (9) offers the necessary security to prevent access to the moving parts, which allows the installation of a removable and easily removable front cover (10), arranged in correspondence with the opening perimeter suction housing (1) that offers a pleasant aesthetic.
• Said cover (10) has anchoring elements that allow its fixation and separation with respect to the perimeter flange (2) composed of a series of lugs (11) protruding from the inner surface of the cover (10) in correspondence with two holes (12) in the perimeter flange (2).
• the diameter of said lugs (11) is slightly larger than the diameter of the holes (12) for fixing.
• the ends of the lugs (11) have a magnetized base (13) that is fixed on metal washers (14) located at the bottom of the holes (12) .
• the electric motor (3) is covered by a dome (15) approximately semi-oiled, in correspondence with the central hole (16) presented by the front cover (10).
• the air intake is carried out through the central hole (16) of the front cover (10), as well as through the space between the front cover (10) and the perimeter flange (2)
