Abstract

The roller according to the invention essentially comprises a stationary inner axle (1) supporting poles (4), about which exciting coils (3) are arranged. The rotating outer part or bush (7) is equipped with bars (9) made of a material of high electrical resistivity; these bars are short-circuited by means of rings (13), so that, when the bush (7) is set in rotation, they experience high electrical currents, the result of this being a rise in their temperature and a transfer of heat to the bush, this transfer being virtually complete as a result of the thermal insulation (11) provided round the stationary axle (1). <IMAGE>

Description

La présente invention a pour objet un tambour tournant à chauffage par induction, plus particulièrement destiné au repassage des fourrures à poils, des tissus ou articles similaires, qui fait appel à un principe nouveau et qui permet une économie considérable d'énergie pour l'usager en même temps qu'une réduction importante du temps nécessaire à l'obtention des températures de fonctionnement.The subject of the present invention is a rotary drum with induction heating, more particularly intended for ironing pile fur, fabrics or similar articles, which uses a new principle and which allows a considerable saving of energy for the user. at the same time as a significant reduction in the time required to obtain operating temperatures.

On sait que dans les tambours de repassage de type usuel, la génération de chaleur à l'intérieur du tambour est assurée par de la vapeur à haute température, par le moyen d'une circulation d'huile chaude ou encore à l'aide de résistances électriques.It is known that in conventional ironing drums, the generation of heat inside the drum is ensured by steam at high temperature, by means of a circulation of hot oil or even using electrical resistances.

Il convient cependant d'observer que dans le cas où l'on introduit des fluides à température élevée à l'intérieur du tambour, il faut avoir recours à des raccords pour l'entrée et la sortie du fluide de chauffage, les choses étant compliquées par la présence d'une partie tournante ; lorsqu'on utilise dans le tambour des résistances électriques il y a lieu de prévoir un collecteur à anneaux associé à des balais fixes ou tournants, ce qui implique une consommation notable de courant électrique par rapport à la quantité de chaleur qui est réellement employée pour l'opération de repassage.It should however be observed that in the case where fluids of high temperature are introduced inside the drum, it is necessary to have recourse to fittings for the inlet and the outlet of the heating fluid, the things being complicated by the presence of a rotating part; when using electric resistors in the drum, a ring collector associated with fixed or rotating brushes should be provided, which implies a significant consumption of electric current compared to the amount of heat which is actually used for the ironing operation.

La présente invention a pour but de réaliser un tambour chauffant, notamment pour le repassage de fourrures ou similaires, qui comprend essentiellement un alternateur à induit extérieur tournant, associé à un circuit électrique du type à barreaux en court-circuit, le circuit inducteur étant constitué par une série de bobines fixes préalablement excitées et la chaleur apportée à la partie extérieure étant fournie par l'échauffement dû à la circulation du courant à l'intérieur des barreaux du circuit induit extérieur, lequel est mis en rotation par un moteur auxiliaire relié à la partie extérieure du tambour, par exemple à l'aide d'un système de courroies et poulies ou autre moyen équivalent.The object of the present invention is to produce a heating drum, in particular for ironing furs or the like, which essentially comprises an alternator with rotating external armature, associated with an electrical circuit of the type with shorted bars, the inductor circuit being constituted by a series of previously excited fixed coils and the heat supplied to the external part being supplied by the heating due to the circulation of current inside the bars of the external induced circuit, which is rotated by an auxiliary motor connected to the outer part of the drum, for example using a system of belts and pulleys or other equivalent means.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une coupe longitudinale d'un tambour de repassage établi conformément à l'invention.
  • Fig. 2 et 3 sont des coupes transversales suivant les plans respectivement indiqués en II-II et en III-III en fig. 1.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a longitudinal section of an ironing drum established in accordance with the invention.
  • Fig. 2 and 3 are cross sections along the planes respectively indicated in II-II and III-III in fig. 1.

Le tambour chauffant représenté en fig. 1 comprend essentiellement un axe 1 convenablement fixé par le moyen d'étriers 2 et autour duquel sont disposées des bobines d'excitation 3. Chacune de celles-ci est enroulée autour du pôle correspondant 4 porté par l'axe central 1, cette fixation étant assurée par le moyen de vis 5.The heating drum shown in fig. 1 essentially comprises an axis 1 suitably fixed by means of stirrups 2 and around which excitation coils are arranged 3. Each of these is wound around the corresponding pole 4 carried by the central axis 1, this fixing being secured by means of screws 5.

Sur l'axe central 1 sont en outre disposés des paliers radiaux 6 propres à permettre la rotation d'une partie extérieure ou douille 7, entraînée par exemple par un moteur électrique, non représenté, avec interposition d'un système de courroies ou d'engrenages associé à la poulie référencée 8. Cette douille extérieure 7 supporte des barreaux 9 en un alliage métallique à haute résistivité électrique, qui constituent un circuit fermé à travers des anneaux 13, ce circuit étant similaire aux cages du type de celles utilisées dans les machines asynchrones de manière à faire fonction de circuit induit.On the central axis 1 are also arranged radial bearings 6 suitable for allowing the rotation of an external part or socket 7, driven for example by an electric motor, not shown, with the interposition of a system of belts or gears associated with the pulley referenced 8. This outer sleeve 7 supports bars 9 of a metal alloy with high electrical resistivity, which constitute a closed circuit through rings 13, this circuit being similar to cages of the type used in machines asynchronous so as to function as an induced circuit.

Dans ces conditions, lorsqu'on alimente convenablement en courant continu les bobines d'excitation 3 montées sur les pôles 4, on engendre un flux magnétique qui en pénétrant dans le circuit induit fermé en court-circuit lorsque la douille 7 est mise en rotation, provoque bien entendu l'obtention d'une force électromotrice dans ledit circuit induit en assurant de la sorte une circulation de courant à l'intérieur de celui-ci.Under these conditions, when the DC coils 3 mounted on the poles 4 are suitably supplied with direct current, a magnetic flux is generated which enters the closed induced circuit in short circuit when the socket 7 is rotated, of course causes an electromotive force to be obtained in said induced circuit, thereby ensuring a flow of current inside it.

De cette manière l'échauffement ainsi provoqué dans les barreaux 9 fait en sorte que ceux-ci cèdent de la chaleur à la douille extérieure de l'ensemble, en permettant en conséquence d'élever la température du tambour jusqu'aux valeurs désirées en fonction des besoins.In this way the heating thus caused in the bars 9 causes them to give off heat to the outer sleeve of the assembly, thereby allowing the temperature of the drum to be raised to the desired values depending needs.

Sur le dessin on peut voir en outre qu'à l'intérieur de l'axe central 1 est ménagé un canal axial de ventilation associé à des perforations 12, afin d'opérer le refroidissement des bobines d'excitation 3. On a également prévu un empilage de tôles 10 monté autour de l'ensemble des barreaux 9, ainsi qu'une isolation thermique 11 disposée contre la face extérieure de la partie fixe en vue d'éviter qu'une partie de la chaleur engendrée à l'intérieur des barreaux 9 ne soit dispersée vers l'intérieur et non vers l'extérieur comme requis.In the drawing we can also see that inside the central axis 1 is formed an axial ventilation channel associated with perforations 12, in order to cool the excitation coils 3. We have also provided a stack of sheets 10 mounted around all of the bars 9, as well as thermal insulation 11 disposed against the outer face of the fixed part in order to prevent part of the heat generated inside the bars 9 is dispersed inward and not outward as required.

Dans ces conditions l'on comprend sans peine que l'adoption de l'ensemble suivant l'invention permet de supprimer les inconvénients usuellement rencontrés dans les agencements de type connu, tels que la présence de raccords d'entrée et de sortie dans le cas du chauffage à l'aide d'un fluide chaud ou celle d'un collecteur à anneaux à balais fixes ou tournants dans le cas du chauffage par résistances électriques. On notera en particulier, en ce qui concerne ce dernier type d'appareillage, qu'on obtient une réduction considérable de la consommation d'énergie électrique à parité de chaleur fournie au tambour tournant et ce par suite du rendement très élevé du système suivant l'invention.Under these conditions it is easily understood that the adoption of the assembly according to the invention makes it possible to eliminate the drawbacks usually encountered in arrangements of known type, such as the presence of inlet and outlet fittings in the case heating using a hot fluid or that of a ring collector with fixed or rotating brushes in the case of heating by electrical resistances. It will be noted in particular, with regard to this latter type of apparatus, that a considerable reduction in the consumption of electrical energy is obtained at parity of heat supplied to the rotating drum and this as a result of the very high efficiency of the system according to the invention.
