    MOUTH OF EXTRACTI ON OR I NSUFFLATI ON OF AI R
    The invention relates to an extraction or air blowing mouth.
    These outlets are connected to ventilation units or other equipment for extracting or blowing air into the building to be treated by means of ducts. These ventilation systems, in particular centralized ventilation systems of the controlled mechanical ventilation type, often installed in the attic or flat roofs, are visible in the housing by these vents which aesthetically mask the air inlet or outlet. .
    These outlets can integrate additional functions, for example an orientation of the air flow by means of flaps, a control of a constant flow, a modulation of the flow according to the hygrometry of the room or a modulation of the flow according a presence in the room.
    In particular, in certain applications, for example in the case of kitchen equipment, it is desired to have two levels of extraction or insufflation flow corresponding to a maximum flow and to an intermediate flow.
    It is known to obtain these two flow levels by means of flaps arranged frontally to the air flow and more or less inclined.
    The pressure drops are, however, relatively large in such an arrangement of front flaps.
    Furthermore, patent document KR 20-2015-0003460 describes a mouth comprising a duct intended to be disposed in a wall and provided with a support flange on the wall, an external front facade plate with a front surface greater than the inner section of the duct and supporting the end of a central shaft also supported by the duct and on which can slide a plate for modulating the air flow rate passing through the mouth. This mouth allows only one level of flow, in its open position.
    The invention solves these problems by proposing an air extraction or insufflation mouth ensuring two levels of flow while restricting the pressure drops and which is of limited size, of optimal aesthetics because having no air passage orifice visible from the outside and of excellent mechanical stability, while being particularly simple to manufacture.
    To do this, the invention provides an air extraction or blowing mouth comprising a duct intended to be disposed in an orifice in a wall and provided with a radial flange for bearing on said wall, a plate of facade integral with said duct and an element for modulating the mobile air flow from an open position to a closed position of the air flow leaving or entering the mouth between said radial duct support flange and said plate front, by axial displacement along the longitudinal axis of said duct, mouth characterized in that said modulating element comprises two parts for guiding the air flow, front and rear, tubulars of longitudinal axis parallel to the longitudinal axis of said duct, these two guide parts being capable of ensuring the passage of the flow of air leaving or entering the mouth between said radial flange for supporting the duct and said front plate in the open position erte and a channel disposed between the two guide parts being able to ensure the passage of the air flow leaving or entering the mouth between said radial flange supporting the duct and said front plate, in an intermediate position between said open position and said closed position.
    The tubular constitution of the guide parts ensures optimum gain in thickness in the thickness of the mouth.
    This arrangement also ensures mechanical robustness of all the parts constituting the mouth.
    The air flow leaving or entering the mouth between said radial support flange of the duct and said front plate flows over substantially 360 degrees and the tubular guide parts ensure its closure on a substantially axisymmetric section. The passage of air in the duct is therefore invisible from the equipped room, which ensures an aesthetic effect.
    In addition, by such a constitution, it is easy by construction to modify the passage section of the air flow through the mouth.
    Thanks to the invention, also, the pressure drop in the open position is greatly reduced, which can make it possible to reduce the operating pressure of the ventilation group, and therefore the noise and consumption generated.
    By "guide part" is meant a part actually cutting the air stream into two parts, continuous and preferably not openwork on the air path.
    According to a preferred embodiment of the invention, the two said tubular air flow guide portions, front and rear, are of the same longitudinal axis as said duct.
    Preferably, the two said tubular air flow guide parts, front and rear, are of radially flared curved generatrix.
    By “curved generator”, we mean the general shape of the guide parts. Potentially, layouts can be placed in specific places.
    This shape of the guide parts ensures optimal guidance of the air flow leaving or entering the mouth between the radial support flange of the duct and said front plate and reduces the pressure losses.
    Advantageously, it comprises an actuator for driving said modulation element held between the rear face of said front plate and said modulation element.
    Preferably, said modulating element comprises a rear tubular part of the same longitudinal axis as said conduit and of straight generator, carrying an external and movable thread from said open position to said closed position, by rotation of this thread in an internal thread of said conduit .
    Said tapping may be discontinuous, to ensure good demolding capacity and to limit the friction problems associated with geometric defects.
    Alternatively, this tapping can also be continuous if it is desired to further limit the pressure drops and the leakage passing through this tapping. However, it is more difficult to manufacture.
    Preferably, said duct carries on its inner face an abutment tenon in axial displacement cooperating with the rear end of said rear tubular part, in the closed position.
    Advantageously, said front guide part comprises a tubular front drive part with the same longitudinal axis as said duct and straight generator, this drive part being intended to be driven by said actuator.
    And said drive part preferably comprises an internal toothing cooperating with a gear linked to said actuator which is a rotary electric motor, this gear having a height strictly greater than the amplitude of movement of said modulating element.
    The front end of said modulating element may comprise at least one tooth ensuring a stop locked in rotation with at least one corresponding tooth arranged on said front plate.
    Preferably, the front end of said front guide part is in substantially sealed abutment against said radial support flange, in the closed position.
    According to another embodiment of the invention, said modulating element comprises a rear tubular support part with the same longitudinal axis as said conduit and of straight generator line, and sliding in translation on the internal face of the conduit.
    According to a first variant, said actuator for driving said modulating element is integral with said front plate or said radial support flange and said modulating element comprises a tapping or a rack cooperating with a screw linked to said actuator which is a rotary motor, this tapping, this rack or this screw having a height strictly greater than the amplitude of movement of said modulation element.
    The internal thread can alternatively be replaced by one or more rack-type or equivalent connections.
    According to a second variant, said drive actuator is connected to an endless screw with an axis substantially perpendicular to the longitudinal axis of said conduit, which it drives in rotation and on which is moved a nut connected by a first articulated lever to said front plate and by a second lever articulated to said modulation element.
    The mouth is preferably equipped with at least one energy recovery device at least partially ensuring its electrical self-supply and providing an electrical signal and in that it comprises an electronic processing device for said electrical signal.
    Alternatively, the mouth can also be powered by replaceable batteries or by a wired power supply from a ventilation group.
    Advantageously, said energy recovery device comprises a turbine disposed within said rear guide part, at the rear of said front guide part, said turbine being connected to a generator transforming its mechanical energy of rotation into said electrical signal. correlated to the air flow through the mouth.
    The energy recovery device can also be a solar panel capturing the lighting of the room to be ventilated, the photovoltaic cell of which is preferably placed on the visible face of the facade plate.
    Said turbine is preferably a helical turbine whose axis of rotation is substantially parallel to the longitudinal axis of said duct.
    Advantageously, said front plate has a front surface greater than the internal section of said duct.

    The front plate 2 is of frontal surface greater than the internal section of the duct 1 and advantageously has its smallest frontal dimension greater than the maximum diameter of said flange 1A of said duct.
    A ventilation installation provided with a fan and a duct network, comprises at least one such mouth in air communication with the network and the fan.
    The modulating element 3 comprises two parts for guiding the air flow, front 3A and rear 3B, tubular with a longitudinal axis parallel to the longitudinal axis A of the duct, these two guide parts being able to ensure the passage of the air flow leaving or entering the mouth between the radial flange 1A for supporting the duct and the front plate 2 in the open position (FIG. 3) and a channel 3C disposed between the two guide parts 3A, 3B being suitable ensuring the passage of the air flow leaving or entering the mouth between the radial flange 1A for supporting the duct and the front plate 2, in an intermediate position (FIG. 2) between the open position and said closed position.
    More specifically, the two said tubular air flow guide parts, front 3A and rear 3B, are of the same longitudinal axis A as the duct and radially flared curved generator line.
    The mouth comprises a drive actuator 4 of the modulation element 3 held between the rear face of the front plate 2 and the modulation element 3.
    The modulating element 3 comprises a rear tubular part 3D of the same longitudinal axis A as the duct 1 and of straight generator, carrying an external thread 3E and movable from the open position to the closed position, by rotation of this thread 3E in a internal thread 1B discontinuous of the duct. The conduit 1 carries on its inner face an abutment tenon in axial displacement and in rotation 1F cooperating with a corresponding tenon of the rear end of the rear tubular part, in the closed position.
    This rear tubular part 3D is also a rear tubular part for supporting the guide parts 3A, 3B by means of balusters 3D1 connecting these guide parts 3A, 3B to one another and with this rear part. These columns 3D1 can be three in number, regularly distributed over the periphery of the guide parts 3A, 3B.
    Furthermore, the front guide part 3A comprises a front tubular drive part 3G with the same longitudinal axis A as the duct and straight generator, this drive part being intended to be driven by the actuator 4. This part d '3G drive has an internal toothing 3H cooperating with a gear 6 linked to the actuator 4 which is a rotary electric motor.
    The front end of the 3G drive part comprises at least one tooth 3I ensuring a stop locked in rotation with at least one corresponding tooth 2A 2A arranged on the front plate 2, and this, for the open position.
    The mouth is also equipped with at least one energy recovery device ensuring at least partially its electrical self-supply and providing an electrical signal and comprises an electronic processing device for this electrical signal.
    According to the embodiment shown, this energy recovery device comprises a helical turbine 7 whose axis of rotation is substantially parallel to the longitudinal axis A of the conduit, disposed within the rear guide part 3B, at the 'rear of the front guide part 3A, and this turbine 7 is connected to a generator 8 transforming its mechanical energy of rotation into the electrical signal correlated to the air flow rate passing through the mouth. This correlation can be improved by adding a value representing the position of the modulation element.
    An actuator control device 4 is included on or connected to a printed circuit (not shown) on board said mouth and is controlled according to the state of a sensor connected to said printed circuit and / or according to a measurement of flow in the sheath in fluid communication with the mouth and / or according to an ordering instruction supplied by the user.

    Thanks to this enslavement, the mouth can therefore be arranged in three positions:
    - A closed position shown in Figure 1, where the front end of the front guide portion 3A is in substantially sealed abutment against the radial support flange 1A;
    - An intermediate position shown in FIG. 2, where the air flow leaving or entering the mouth between the radial flange 1A for supporting the duct and the front plate 2 can circulate in the channel 3C disposed between the two parts guide 3A, 3B;
    - An open position shown in Figure 3, where the front end of the front guide portion 3A abuts against the front plate 2 and where the air flow circulates both in the channel 3C and at rear of the rear guide portion 3B.
    According to the embodiment shown, the turbine 7 is arranged so as to be in the air flow passing through the channel 3C, in the intermediate position and in the open position. In the open position, the air flow circulating at the rear of the rear guide part 3B bypasses the turbine 7, thereby reducing the pressure losses and limiting the speed of rotation of the turbine. However, it can also be envisaged to arrange the turbine, so that it is in the air flow passing through the channel 3C and also in the air flow circulating at the rear of the rear guide part. 3B.
    Figures 5 to 13 show a second embodiment of a mouth according to the invention.
    This second embodiment differs essentially from the first previous embodiment by the following characteristic. The modulating element 30 comprises a rear tubular support part 30D with the same longitudinal axis A as the duct 10 and a straight generator line, and sliding on the internal face of the duct, in a simple translation parallel to the axis A.
    This support part 30D carries two parts for guiding the air flow, front 30A and rear 30B, tubular with a longitudinal axis to the longitudinal axis A of the conduit 10, the support part comprising orifices 30D2 capable of ensuring the passage of the air flow leaving or entering the mouth between the flange 1 OA radial support of the duct and the front plate 20 towards the guide parts 30A, 30B, in the open position (FIG. 7), and towards a channel 30C disposed between the two guide parts, in an intermediate position (Figure 6) between the open position and said closed position.
    These two said guide portions 30A, 30B of the tubular air flow, front and rear, are of the same longitudinal axis A as the duct 10 and of radially flared curved generatrix.
    As best seen in FIG. 9, the front end of the modulation element 30, and more precisely of the front guide part 30A, comprises at least one notch 30A1 for interlocking with a fixed part of the front plate 20 More specifically, the front plate 20 is integral with the duct 10 by means of feet 20A carried by the rear of this front plate and screwed and this fixed part of the front plate 20 is one of these feet 20A including a flange longitudinal 20A1 is fitted into this notch 30A1.
    According to a first variant shown in Figures 5 to 8, the drive actuator 40 of the modulating element 30 is integral with the front plate 20 and the modulating element 30 comprises a thread 70 cooperating with a screw60 linked to the actuator 40 which is a rotary motor, this tapping 70 or this screw having a height strictly greater than the amplitude of movement of said modulation element 30.
    More specifically, this internal thread 70 consists of a threaded section projecting in front of the front guide part 30A.
    This tapping can take the form of a slightly oblique toothed rack. An actuator control device 40 is included on a printed circuit on board said mouth and is controlled according to the state of a sensor connected to said printed circuit and / or according to a flow measurement in the sheath in communication of fluid with the mouth and / or according to an ordering instruction supplied by the user.
    Thanks to this enslavement, the mouth can therefore be arranged in three positions:
    a closed position shown in Figure 5, where the front end of the front guide portion 30A is in substantially sealed abutment against the radial support flange 10A;
    an intermediate position shown in FIG. 6, where the air flow leaving or entering the mouth between the radial flange 10A for supporting the duct and the front plate 20 can circulate in the channel 30C disposed between the two parts of guide 30A, 30B;
    an open position shown in FIG. 7, where the front end of the front guide part 30A abuts against the front plate 20 and where the air flow circulates both in the channel 30C and at the rear of the rear guide portion 30B.
    According to a second variant shown in FIGS. 10 to 14, the drive actuator 40 ′ is connected to an endless screw 80 with an axis substantially perpendicular to the longitudinal axis of said conduit, which it drives in rotation and on which is displaced a nut 90 connected by a first lever 100A articulated to the front plate 20 and by a second lever 100B articulated to the modulation element 30 and more precisely to the front guide part 30A.
    The part carrying the actuator 40 ′ and the worm 80 also carries a third lever 100C articulated to the front plate 20 and by a fourth lever 100D articulated to said modulation element 30 and more precisely to the front guide part 30A, so to strengthen the mechanical strength.
    An actuator control device 40 'is included on a printed circuit on board said mouth and is controlled according to the state of a sensor connected to said printed circuit and / or according to a flow measurement in the sheath in communication fluid with the mouth and / or according to a control instruction supplied by the user.
    Thanks to this enslavement, the mouth can therefore be arranged in three positions:
    a closed position shown in Figure 10, where the front end of the front guide portion 30A is in substantially sealed abutment against the radial support flange 10A;
    an intermediate position shown in Figure 11, where the air flow leaving or entering the mouth between the flange 1 0A radial support of the conduit and the front plate 20 can circulate in the channel 30C disposed between the two parts guide 30A, 30B;
    an open position shown in FIG. 12, where the front end of the front guide part 30A abuts against the front plate 20 and where the air flow circulates both in the channel 30C and at the rear of the rear guide portion 30B.
    According to the embodiment shown, as before, the turbine is arranged so as to be in the air flow passing through the channel 30C, in the intermediate position and in the open position. In the open position, the air flow circulating at the rear of the rear guide portion 30B bypasses the turbine, thereby reducing the pressure losses and limiting the speed of rotation of the turbine. However, it can also be envisaged to arrange the turbine, so that it is in the air flow passing through the channel 30C and also in the air flow circulating at the rear of the rear guide part. 30B.
    In the case of the embodiments and their variants described above, the front guide parts 3A, 30A and rear 5 3B, 30B can be of different shapes, not necessarily circular, to adapt to a general shape of the mouth or take takes into account the size of a component used in kinematics. In addition, the ratios of the passage channels both at the flared part and at the cylindrical part can be variable according to different criteria, for example compromise between pressure drops, air speed at the turbine , to optimize the turbine start-up flow or limit its maximum speed, more precise modulation zones, acoustic consideration, etc.
