Description
La présente invention concerne un générateur électrique pour fournir de l'énergie électrique à un composant entraîné en rotation autour d'un axe.The present invention relates to an electric generator for supplying electrical energy to a component driven in rotation about an axis.
Lorsque l'on souhaite alimenter en énergie électrique un composant entraîné en rotation autour d'un axe, on utilise généralement les bagues solidaires de l'axe coopérant avec des frotteurs entraînés en rotation avec le composant.When it is desired to supply electrical energy to a component driven in rotation about an axis, generally used the rings integral with the axis cooperating with wipers driven in rotation with the component.
C'est notamment le cas dans les appareils sèche-linge à tambour rotatif ou l'on souhaite alimenter des électrodes de mesure de la résistance électrique du linge contenu dans le tambour afin de déterminer son niveau d'humidité.This is particularly the case in tumble dryers with a rotary drum where it is desired to supply electrodes for measuring the electrical resistance of the laundry contained in the drum in order to determine its humidity level.
Un tel mode d'alimentation n'est toutefois plus possible pour des vitesses de rotation trés élevées, comme c'est le cas dans les machines lavantes/séchantes dont le tambour peut atteindre des vitesses de rotation de l'ordre de 1200 à 1500/tours minute lors des phases d'essorage.However, such a feeding mode is no longer possible for very high rotation speeds, as is the case in washing / drying machines in which the drum can reach rotation speeds of the order of 1200 to 1500 / rpm during the spin phases.
La présente invention vise à palier cet inconvénient.The present invention aims to overcome this drawback.
A cet effet, l'invention a pour objet un générateur électrique pour fournir de l'énergie électrique à un composant entraîné en rotation autour d'un axe, caractérisé par le fait qu'il comprend un stator solidaire dudit composant et un rotor solidaire d'un support de rotor, ledit support de rotor étant monté sur ledit composant de manière que le mouvement de rotation du composant entraîne un mouvement relatif du rotor par rapport au stator.To this end, the subject of the invention is an electric generator for supplying electrical energy to a component driven in rotation about an axis, characterized in that it comprises a stator secured to said component and a rotor secured to a rotor support, said rotor support being mounted on said component so that the rotational movement of the component causes relative movement of the rotor relative to the stator.
Par conséquent, l'ensemble du générateur électrique selon l'invention est entraîné dans le mouvement du composant à alimenter de sorte qu'il n'est plus nécessaire de recourir aux dispositifs à bagues et frotteurs de l'art antérieur. Consequently, the assembly of the electric generator according to the invention is driven in the movement of the component to be supplied so that it is no longer necessary to resort to the devices with rings and wipers of the prior art.
Le mouvement relatif du rotor par rapport au stator est provoqué par le mouvement de rotation du composant auquel le générateur est relié par l'intermédiaire de sont stator et de son support de rotor.The relative movement of the rotor relative to the stator is caused by the rotational movement of the component to which the generator is connected via its stator and its rotor support.
Dans un premier mode de réalisation de l'invention, applicable plus particulierement lorsque l'axe de rotation est sensiblement horizontal, ledit support de rotor comprend une masse pendulaire montée à rotation autour d'un axe solidaire du stator et sensiblement parallèle à l'axe de rotation du composant.In a first embodiment of the invention, applicable more particularly when the axis of rotation is substantially horizontal, said rotor support comprises a pendulum mass mounted for rotation about an axis integral with the stator and substantially parallel to the axis component rotation.
Plus particulièrement le rotor et le stator peuvent être de forme géneralement cylindrique d'axe confondu avec l'axe de rotation de la masse pendulaire.More particularly, the rotor and the stator can be generally cylindrical in shape with an axis coincident with the axis of rotation of the pendulum mass.
Dans ce cas, le stator étant solidaire du composant est simultanément l'objet d'un mouvement de rotation d'axe parallèle à l'axe de rotation du composant et d'un mouvement de translation circulaire autour de l'axe de rotation du composant. En revanche le rotor dont l'orientation est maintenue sensiblement constante par la force de gravite s'exerçant sur la masse pendulaire, effectue uniquement un mouvement de translation circulaire autour de l'axe de rotation du composant. En conséquence dans un repère lié au stator, le rotor effectue un mouvement de rotation de même fréquence et de même sens que la rotation du composant autour de son axe.In this case, the stator being integral with the component is simultaneously the object of a rotary movement of axis parallel to the axis of rotation of the component and of a circular translation movement around the axis of rotation of the component . On the other hand, the rotor, the orientation of which is kept substantially constant by the gravitational force exerted on the pendulum mass, performs only a circular translational movement around the axis of rotation of the component. Consequently, in a reference linked to the stator, the rotor performs a rotational movement of the same frequency and in the same direction as the rotation of the component around its axis.
Dans un deuxième mode de réalisation, ledit support de rotor comprend une lame vibrante, susceptible de vibrer dans un plan sensiblement perpendiculaire à l'axe de rotation du composant, et portant le rotor à une de ses extrémités et encastrée à son autre extrémité dans ledit composant de maniere que le rotor vibre en vis à vis du stator. In a second embodiment, said rotor support comprises a vibrating blade, capable of vibrating in a plane substantially perpendicular to the axis of rotation of the component, and carrying the rotor at one of its ends and embedded at its other end in said component so that the rotor vibrates opposite the stator.
Dans ce mode de réalisation la lame excitée par le mouvement de rotation du composant est par conséquent l'objet d'oscillations entretenues entraînant une vibration du rotor en vis à vis du stator.In this embodiment, the blade excited by the component's rotational movement is therefore subject to sustained oscillations, causing the rotor to vibrate opposite the stator.
Dans tous les cas, on peut réaliser le générateur électrique de l'invention de manière particulièrement simple en realisant le stator sous forme d'un circuit bobiné et le rotor sous forme d'un aimant permanent.In all cases, the electrical generator of the invention can be produced in a particularly simple manner by producing the stator in the form of a wound circuit and the rotor in the form of a permanent magnet.
L'énergie électrique est recueillie aux bornes du stator et peut donc directement alimenter le composant qui est solidaire de ce stator.The electrical energy is collected at the terminals of the stator and can therefore directly supply the component which is integral with this stator.
On décrira maintenant à titre d'exemple non limitatif deux modes de réalisation de l'invention en référence aux dessins schématiques annexés dans lesquels - la figure 1 illustre une application de l'invention au
domaine des appareils sèche-linge, - la figure 2 représente un premier mode de réalisation, et - la figure 3 représente un deuxième mode de réalisation.Two embodiments of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which - FIG. 1 illustrates an application of the invention to
field of tumble dryers, - Figure 2 shows a first embodiment, and - Figure 3 shows a second embodiment.
La figure 1 représente le tambour 1 à axe horizontal d'un appareil sèche-linge susceptible d'être entraîné en rotation autour d'un axe 2 à l'aide d'un moteur non représenté.FIG. 1 shows the drum 1 with a horizontal axis of a dryer device capable of being rotated around an axis 2 using a motor, not shown.
Le tambour 1 porte à sa surface interieure des nervures 3 provoquant l'entraînement du linge lors de la rotation du tambour.The drum 1 carries on its inner surface ribs 3 causing the washing of the linen during the rotation of the drum.
A l'intérieur d'une des nervures est disposée une enceinte 4 portant à sa surface deux électrodes 5 de mesure de la résistance électrique du linge afin d'en déduire son niveau d'humidité. Le composant 4 est fixé dans la nervure 3 de telle sorte que les électrodes 5 se trouvent en vis à vis de trous formés dans la nervure 3 de maniere à se trouver au contact du linge au cours de la rotation du tambour 1.Inside one of the ribs is an enclosure 4 carrying on its surface two electrodes 5 for measuring the electrical resistance of the laundry in order to deduce its humidity level. The component 4 is fixed in the rib 3 so that the electrodes 5 are opposite holes formed in the rib 3 so as to be in contact with the linen during the rotation of the drum 1.
Afin d'alimenter les électrodes 5 et tous d'autres moyens electroniques, un générateur électrique selon l'invention est disposé à l'intérieur du composant 4.In order to supply the electrodes 5 and all other electronic means, an electric generator according to the invention is placed inside the component 4.
Le générateur électrique de la figure 2 comporte de façon connu un rotor 6 constitué par un aimant permanent susceptible de tourner a l'intérieur d'un rotor bobiné 7.The electric generator of FIG. 2 comprises in known manner a rotor 6 constituted by a permanent magnet capable of rotating inside a wound rotor 7.
Le rotor 6 est monté dans le stator 7 sur un axe 8 et est solidaire d'une masse pendulaire 9.The rotor 6 is mounted in the stator 7 on an axis 8 and is integral with a pendulum mass 9.
Le stator 7 est solidaire des parois de l'enceinte 4 et l'axe 8 est monté solidaire du rotor 7.The stator 7 is integral with the walls of the enclosure 4 and the axis 8 is mounted integral with the rotor 7.
Lorsque le tambour rotatif 1 tourne autour de l'axe 2, la masse pendulaire 9 maintient par gravité le rotor 6 dans une orientation constante alors que le stator 7, entraîné dans la rotation du tambour 1, effectue un tour par tour du tambour. Il en résulte aux bornes du bobinage du stator, une tension qui peut être utilisée pour alimenter les différents éléments contenus dans l'enceinte 4.When the rotary drum 1 rotates about the axis 2, the pendulum mass 9 keeps the rotor 6 by gravity in a constant orientation while the stator 7, driven in the rotation of the drum 1, performs a turn by turn of the drum. This results at the terminals of the stator winding, a voltage which can be used to supply the various elements contained in the enclosure 4.
Dans le mode de réalisation de la figure 3, une lame élastique 10, allongée dans une direction sensiblement normale à l'axe 2, est encastrée à son extrémité 11 dans la paroi de l'enceinte 4 et porte à son autre extrémité 12 un aimant permanent 13 Un bobinage 14 est disposé en vis à vis de l'aimant 13 dans la position de repos de la lame 1D.In the embodiment of Figure 3, an elastic blade 10, elongated in a direction substantially normal to the axis 2, is embedded at its end 11 in the wall of the enclosure 4 and carries at its other end 12 a magnet permanent 13 A winding 14 is arranged opposite the magnet 13 in the rest position of the blade 1D.
Lors de la rotation du tambour 1, la lame 10 sollicitée alternativement dans un sens et dans l'autre du fait du mouvement du tambour, vibre en entraînant l'aimant 13 alternativement dans un sens puis dans l'autre de sorte que l'aimant se comporte à la manière du rotor d'un alternateur dont le bobinage constitue le stator. Ce mouvement alternatif de l'aimant 13 en vis à vis de la bobine 14 génère aux bornes de la bobine 14 une tension alternative pouvant être utilisée pour l'alimentation des circuits contenus dans l'enceinte 4. During the rotation of the drum 1, the blade 10 which is acted on alternately in one direction and in the other due to the movement of the drum, vibrates by driving the magnet 13 alternately in one direction then in the other so that the magnet behaves like the rotor of an alternator whose winding constitutes the stator. This reciprocating movement of the magnet 13 opposite the coil 14 generates at the terminals of the coil 14 an alternating voltage which can be used to supply the circuits contained in the enclosure 4.
