Description
La présente invention concerne un sélecteur rotatif pour appareils électroménagers, ce sélecteur servant d'interface entre la partie électrique et électronique d'un appareil électroménager, tel qu'une machine à laver le linge, et l'utilisateur de cet appareil électroménager. Plus particulièrement, cette invention se rapporte à un sélecteur rotatif dont l'axe porte un organe de commande tournant avec cet axe et coopérant avec deux interrupteurs de puissance à lame opposés, qui peuvent être commutés simultanément lors de la rotation de l'organe de commande tournant, ces interrupteurs étant capables de couper l'alimentation électrique générale de la machine à laver, ou autre appareil électroménager, le sélecteur étant prévu pour être monté sur un circuit imprimé principal, et pour être disposé, après montage dans l'appareil électroménager concerné, de sorte que son axe puisse être manipulé par l'utilisateur de cet appareil.The present invention relates to a rotary selector for apparatus appliances, this selector serving as an interface between the electrical part and electronic appliance, such as a washing machine, and the user of this appliance. More particularly, this The invention relates to a rotary selector whose axis carries an organ of rotary control with this axis and cooperating with two switches of opposing blade power, which can be switched simultaneously during the rotation of the rotary control member, these switches being capable of to cut off the general power supply of the washing machine, or other appliance, the selector being intended to be mounted on a circuit printed form, and to be arranged, after mounting in the device appliance concerned, so that its axis can be manipulated by the user of this device.
Dans le domaine technique des appareils électroménagers, on connaít des tels sélecteurs rotatifs qui sont assemblés sur des circuits imprimés soudables "à la vague", et qui sont destinés à couper des courants de basse puissance et des courants de forte puissance.In the technical field of household appliances, know such rotary selectors that are assembled on circuits "wave" weldable imprints, which are intended to cut currents low power and high power currents.
Ces sélecteurs rotatifs n'intègrent qu'une partie de la connectique de puissance nécessaire aux fonctions de la machine à laver, ou autre appareil électroménager. Il faut ajouter des pistes conductrices sur le circuit imprimé, pour relier le sélecteur aux composants de connexion. Cet agencement de pistes et connecteurs occupe de la place sur le circuit imprimé, ce qui entraíne un surcoût. En effet, il est imposé, d'après la norme IEC 60730 d'avoir une distance supérieure à 3,2 millimètres entre ligne et neutre et entre ligne et basse puissance. De plus, pour faire passer des courants de forte puissance sur des circuits imprimés, il est souvent nécessaire d'utiliser des pistes ayant une épaisseur de cuivre de 70 microns, ce qui en augmente le coût. A cela s'ajoute le prix d'achat des connecteurs additionnels.These rotary selectors integrate only part of the connection power required for the functions of the washing machine, or other appliance home appliance. We must add conductive tracks on the circuit board, to connect the selector to the connection components. This arrangement of tracks and connectors occupies space on the printed circuit, which leads to An additional cost. Indeed, it is imposed, according to the IEC 60730 standard, to have a distance greater than 3.2 millimeters between line and neutral and between line and low power. In addition, to pass high power currents printed circuit boards, it is often necessary to use tracks with a copper thickness of 70 microns, which increases the cost. To that the purchase price of the additional connectors is added.
Par ailleurs, les sélecteurs rotatifs du commerce, prévus pour être montés sur des circuits imprimés, et comportant des interrupteurs de faibles et forts courants, sont basés sur un principe de codage numérique avec courant de faible niveau, qui impose la présence de cinq entrées vers le microprocesseur associé.In addition, commercial rotary selectors intended to be mounted on printed circuits, and having weak switches and strong currents, are based on a digital coding principle with current low level, which requires the presence of five entries to the associated microprocessor.
La présente invention vise à éviter ces inconvénients des sélecteurs rotatifs actuels, en fournissant un sélecteur du type considéré, perfectionné de manière à minimiser la surface du circuit imprimé sur lequel ce sélecteur est soudé, et à minimiser aussi le nombre des connexions de puissance et aussi des connexions avec le microprocesseur, tout en offrant une solution plus "souple" pour faciliter l'adaptation du sélecteur aux divers cas d'application.The present invention aims to avoid these disadvantages of current rotary selectors, by providing a selector of the type considered, perfected so as to minimize the surface of the printed circuit board on which this selector is welded, and to minimize also the number of connections of power and also connections with the microprocessor, while offering a more "flexible" solution to facilitate the adaptation of the selector to the various cases application.
A cet effet, l'invention a pour objet un sélecteur rotatif pour appareils électroménagers, du genre précédemment défini, comportant un axe qui est orienté perpendiculairement au circuit imprimé principal et qui porte un organe de commande tournant coopérant avec deux interrupteurs de puissance à lame opposés, ce sélecteur rotatif étant caractérisé par le fait qu'il comporte une série de bornes électriques de puissance, situées dans des plans parallèles à l'axe précité, comprenant au moins deux bornes consécutives associées respectivement aux deux interrupteurs de puissance, et deux autres bornes consécutives reliées directement entre elles, à l'intérieur du boítier du sélecteur, selon une configuration en "U" formant un pont entre ces deux dernières bornes, certaines bornes étant prolongées par des broches soudables qui traversent la base du boítier, constituée par un circuit imprimé de codage dont les pistes conductrices sont dirigées vers l'intérieur du boítier du sélecteur, lesdites broches étant aptes à être soudées sur le circuit imprimé principal recevant ledit sélecteur.For this purpose, the subject of the invention is a rotary selector for appliances, of the kind previously defined, having an axis which is oriented perpendicular to the main printed circuit and rotary control member cooperating with two switches of opposite blade power, this rotary selector being characterized by the fact that has a series of electrical power terminals, located in planes parallel to the aforementioned axis, comprising at least two terminals consecutive associated respectively with the two power switches, and two other consecutive terminals connected directly to each other, inside selector housing, in a "U" configuration forming a bridge between these last two terminals, some terminals being extended by pins weldable through the base of the housing, constituted by a circuit board of coding whose conductive tracks are directed towards the inside of the housing of the selector, said pins being able to be welded to the circuit board main receiving said selector.
Grâce à ces dispositions, qui ramènent sur le sélecteur rotatif une partie des fonctions actuellement portées par le circuit imprimé principal, le nombre de connexions de forte puissance qui passent par ce circuit imprimé peut être minimisé, on évite aussi l'utilisation de composants supplémentaires pour les connexions de puissance, et les connexions du sélecteur ou de ses bornes avec le circuit imprimé principal sont facilitées. L'agencement de bornes proposé simplifie aussi les connexions avec les constituants de l'appareil électroménager concerné, tel que machine à laver. Le fait que le circuit imprimé de codage soit distinct du circuit imprimé principal, sur lequel est monté le sélecteur, permet lui aussi de limiter la surface du circuit imprimé principal, et de simplifier les connexions entre le sélecteur et le circuit imprimé principal.Thanks to these arrangements, which bring back on the rotary selector a part of the functions currently carried by the main printed circuit board, the number of high power connections that go through this circuit board can be minimized, it also avoids the use of additional components for power connections, and the connections of the selector or its terminals with the main PCB are facilitated. The layout of terminals proposed also simplifies connections with the components of the device Appliances concerned, such as washing machine. The fact that the circuit coded form is distinct from the main printed circuit board, on which is mounted the selector, also allows to limit the surface of the circuit board principle, and to simplify the connections between the selector and the circuit board main.
Plus particulièrement, dans l'application du sélecteur rotatif selon l'invention à une machine à laver, les bornes de la série de bornes de puissance de ce sélecteur sont reliées à un élément chauffant, à un pressostat et à un contact de relais, de manière à réaliser un montage électrique en série de ces trois éléments ; les deux bornes directement reliées entre elles par le pont en "U" peuvent en particulier réaliser ici le montage en série de l'élément chauffant et du pressostat, sans passer par le circuit imprimé.More particularly, in the application of the rotary selector according to the invention to a washing machine, the terminals of the series of terminals of power of this selector are connected to a heating element, to a pressure switch and to a relay contact, so as to provide a series electrical connection of these three elements; the two terminals directly connected to each other by the "U" bridges can in particular realize here the series assembly of the element heating and pressure switch, without going through the circuit board.
Selon un autre aspect de l'invention, le sélecteur rotatif comporte, sur une face frontale de son organe de commande tournant, des balais frottants qui sont prévus pour coopérer avec les pistes conductrices formées sur le circuit imprimé de codage situé à la base de ce sélecteur, les balais et les pistes correspondantes étant agencés de manière à réaliser une fonction de codage, par exemple pour la sélection des programmes d'une machine à laver. Les pistes conductrices du circuit imprimé de codage, par exemple en carbone, sont des pistes résistives ou non résistives, et peuvent être associées ou non à des résistances électriques extérieures, une mémorisation des valeurs de résistances correspondant aux positions sélectionnables étant prévue.According to another aspect of the invention, the rotary selector comprises, on a front face of its rotating control member, brooms rubbers which are provided to cooperate with the formed conductive tracks on the coding circuit board located at the base of this selector, the brooms and the corresponding tracks being arranged to perform a function coding, for example for the selection of programs of a machine to wash. The conductive tracks of the coding circuit, for example in carbon, are resistive or non-resistive, and may be associated or not to external electrical resistances, a memorization of resistor values corresponding to the selectable positions being planned.
Cet agencement permet, grâce à un programme élaboré réalisant l'enregistrement et la mémorisation préalable dans le microprocesseur de la carte électronique finale, de façon temporaire ou définitive, des valeurs de résistances correspondant aux positions sélectionnables par l'utilisateur, de réduire à deux au maximum le nombre des entrées analogiques du microprocesseur, pour vingt-quatre positions du sélecteur. Les variations de résistances résultant de la fabrication, du temps ou de l'usure peuvent être automatiquement corrigées par autoadaptation, gérée par le microprocesseur. Grâce à cette solution, on obtient une grande "souplesse" pour l'adaptation du sélecteur et du circuit imprimé de codage à des variantes, concernant le nombre et l'angulation des positions du sélecteur.This arrangement allows, thanks to an elaborate program realizing recording and prior storage in the microprocessor of the final electronic map, either temporarily or permanently, values of resistors corresponding to the positions selectable by the user, reduce to no more than two the number of analogue inputs microprocessor, for twenty-four selector positions. Variations of resistances resulting from manufacture, time or wear may be automatically corrected by autoadaptation, managed by the microprocessor. Thanks to this solution, we obtain a great "flexibility" for the adaptation of the selector and the coding circuit to variants, concerning the number and angulation of the selector positions.
Le fait que les pistes conductrices du circuit imprimé de codage soient dirigées vers l'intérieur du boítier du sélecteur facilite aussi le montage du sélecteur sur le circuit imprimé principal, tout en assurant une bonne protection des pistes conductrices du circuit imprimé de codage contre les pollutions, et en garantissant le bon fonctionnement mécanique des contacts frottants au niveau de ce circuit imprimé de codage.The fact that the conductive tracks of the coding circuit are directed towards the inside of the selector housing also facilitates assembly selector on the main PCB, while ensuring good protection of the conductive tracks of the coding circuit against pollution, and ensuring the proper mechanical functioning of the contacts rubbing at this coding circuit.
L'invention sera mieux comprise à l'aide de la description qui suit,
en référence au dessin schématique annexé représentant, à titre d'exemples,
des formes d'exécution de ce sélecteur rotatif pour appareils électroménagers :
Les figures 1 et 2 montrent un sélecteur rotatif, désigné dans son
ensemble par la référence 1, qui est monté et notamment soudé sur un circuit
imprimé principal 2. Le sélecteur rotatif 1 possède un boítier isolant 3, dont
certaines parties ont été supprimées sur le dessin de manière à rendre visibles
les composants internes de ce sélecteur 1. La base du boítier isolant 3 est
constituée par un circuit imprimé auxiliaire dit de codage 31, placé au-dessus
du circuit imprimé principal 2, parallèlement à celui-ci.Figures 1 and 2 show a rotary selector, designated in its
together by the
Le sélecteur rotatif 1 possède un axe d'actionnement 4, monté
tournant, qui est orienté perpendiculairement au plan du circuit imprimé 2.
Lorsque l'ensemble est définitivement installé sur un appareil électroménager,
tel que lave-linge, lave-vaisselle ou sèche-linge, l'axe 4 du sélecteur rotatif 1
est lié à un organe de manoeuvre extérieur, tel qu'un bouton rotatif,
manoeuvrable par l'utilisateur de l'appareil électroménager concerné.The
L'axe 4 possède un organe de commande 4a, tournant avec cet
axe 4, qui coopère, dans une position angulaire déterminée, avec deux
interrupteurs de puissance à lame 5 et 6, disposés tête-bêche et de part et
d'autre de cet axe 4. La lame du premier interrupteur 5 est encastrée, par une
extrémité, sur une borne de puissance fixe 7 ; son extrémité opposée, libre,
forme un contact mobile qui coopère avec une borne de puissance 8 portée par
le boítier 3. La lame du second interrupteur 6 est encastrée, par une extrémité,
sur une borne de puissance 9 disposée parallèlement à la précédente borne 8 ;
son extrémité opposée, libre, forme un contact mobile qui coopère avec une
autre borne 10, fixée parallèlement à la première borne 7.The axis 4 has a control member 4a, rotating with this
axis 4, which cooperates, in a given angular position, with two
power switches with
Les deux bornes de puissance voisines 8 et 9 font partie d'une
série de bornes de puissance, portée par le boítier 3, qui dans l'exemple illustré
comporte trois autres bornes de puissance 11, 12 et 13, disposées à la suite
des bornes 8 et 9. Toutes les bornes de cette série sont parallèles et
organisées avec un pas régulier qui est par exemple égal à cinq millimètres, les
plans contenant ces bornes étant parallèles à l'axe 4, donc perpendiculaires au
plan du circuit imprimé 2.The two neighboring power terminals 8 and 9 are part of a
series of power terminals, carried by the
Les deux bornes de puissance 11 et 12 sont directement reliées
entre elles, à l'intérieur du boítier 3, par un pont conducteur 14, selon une
configuration en "U" ― voir figure 2.The two
Comme le montre encore la figure 2, certaines bornes de la série,
et plus particulièrement ici les bornes 8, 9 et 13, sont prolongées par des
broches soudables 15 qui traversent des ouvertures ou encoches 16
correspondantes du circuit imprimé de codage 31 situé à la base du boítier 3,
pour être soudées sur le circuit imprimé 2.As shown again in Figure 2, some terminals of the series,
and more particularly here
La figure 3 est un schéma électrique de la partie "puissance" du
sélecteur rotatif 1, telle que décrite jusqu'ici ; se rapportant plus
particulièrement à un sélecteur pour lave-linge, cette figure 3 indique, dans ce
cas d'application, les branchements réalisables à partir des diverses bornes de
puissance.FIG. 3 is an electrical diagram of the "power" part of the
Les deux bornes 7 et 10, associées respectivement aux deux
interrupteurs à lame 5 et 6, forment des bornes d'entrée raccordées à une
alimentation électrique, avec conducteur de phase 17 et neutre 18.The two
Un élément chauffant 19 est branché entre les deux bornes 12 et
13. Un pressostat 20 avec interrupteur intégré est branché entre les deux
bornes 9 et 11. Grâce à la liaison conductrice réalisée par le pont 14, le
pressostat 20 se trouve ainsi directement mis en série électriquement avec
l'élément chauffant 19. De plus, entre la borne 9 et la borne 13, s'étend une
branche de circuit sur laquelle est intercalé un contact 21 d'un relais 22,
commandé par un microprocesseur, qui autorise ou non la chauffe.A
La figure 4, sur laquelle les composants correspondant à ceux
décrits précédemment sont désignés par les mêmes références, illustre sous
forme de schéma électrique une variante du sélecteur 1 qui est dépourvue des
interrupteurs à lame. Le montage en série de l'élément chauffant 19 et du
pressostat 20 est ici réalisé comme décrit précédemment, notamment avec
l'utilisation des deux bornes 11 et 12 reliées par le pont 14. La série des bornes
comporte ici, au total, six bornes dont deux bornes d'entrée 23 et 24, reliées à
l'alimentation, la borne d'entrée 24 comportant une liaison 25, par le circuit
imprimé, avec la borne 9 reliée au pressostat 20.Figure 4, in which the components corresponding to those
previously described are designated by the same references, illustrated under
electrical schematic form a variant of the
En se référant de nouveau aux figures 1 et 2, l'axe 4 du sélecteur
rotatif 1 est lié en rotation à un organe de commande tournant 26 qui possède
une partie 27 en forme de disque faisant face au circuit imprimé de codage 31.
L'organe tournant 26 possède à sa périphérie des dents 28 coopérant avec un
organe d'indexage, non visible au dessin, permettant de positionner l'axe 4
dans un certain nombre de positions angulaires, par exemple vingt-quatre
positions.Referring again to FIGS. 1 and 2, selector pin 4
1 is rotatably connected to a rotating
Sous la partie 27 en forme de disque, est fixé un ensemble de
balais 29 qui, comme le montre aussi la figure 5, coopère par frottement avec
des pistes conductrices par exemple en carbone 30, résistives ou non, formées
sur le circuit imprimé de codage 31 et ainsi tournées vers l'intérieur du boítier 3.
Les pistes 30, disposées en cercle, sont associées ou non à des résistances
électriques, et elles permettent, en fonction des positions angulaires de l'axe 4,
donc de l'organe de manoeuvre extérieur du sélecteur 1, une commande
"codée" dirigée vers le microprocesseur précité, convenablement étalonné à
cet effet.Under the disk-
L'on ne s'éloignerait pas du cadre de l'invention, telle que définie dans les revendications annexées, en modifiant le nombre des bornes de puissance, leur affectation et l'orientation de la connexion réalisée, ou en modifiant l'agencement des pistes conductrices, selon la destination de ce sélecteur rotatif qui est applicable à tous genres d'appareils électroménagers, à fonctions plus ou moins nombreuses.One would not depart from the scope of the invention, as defined in the appended claims, by modifying the number of the terminals of their assignment and the orientation of the connection made, or modifying the arrangement of the conductive tracks, according to the destination of this rotary selector that is applicable to all kinds of appliances, to more or less numerous functions.
