Definitions
- the invention relates to an electric iron fitted with an automatic safety device comprising a movable body, the electrical supply of the iron being able to be cut off using the movable body either by first time delay means after a short predetermined time. , when the iron is not used in the horizontal position, or by second time delay means after a long predetermined time, when the iron is not used in the vertical position.
- An iron can give rise to certain problems when after being switched on it is left stationary on a cloth. Depending on the temperatures reached, the fabric can be damaged.
- the electronic safety device consists of a mercury switch which cooperates with two timing circuits. These act when the iron remains stationary, one for the horizontal position (short time delay) and the other for the vertical position of the iron (longer time delay).
- the mercury switch which detects the two horizontal and vertical positions consists of a drop of mercury which moves in a bulb fitted with contact pads.
- This mercury switch must be mounted with great precision in the handle of the iron with an inclination of 5.5 ⁇ 0.5 degrees. This also indicates that the same precision is required to ensure proper functioning of the iron.
- the mercury ball does not make the contact in the cylinder anymore and falls to activate the long time delay sufficient to create tissue damage.
- an angle of 5 degrees corresponds approximately to an extra thickness of 2 cm between the ends of the iron. The tolerance of ⁇ 0.5 degree therefore indicates that little is enough for the system to be faulted. The passage from one to the other of the two timers is therefore poorly controlled.
- One of the aims of the invention is therefore to remedy these harmful consequences which can cause deterioration of the linen.
- the invention as defined in the preamble is remarkable in that the movable body is a permanent magnet which, between said horizontal and vertical positions, moves in rotation around an axis to come to cooperate successively with two switches which act respectively on the first and second timing means.

- the length of the rod allows to intervene on the detection precision.
- the switches both consist of a flexible reed switch which cooperates with the permanent magnet.
- the permanent magnet When the iron is in a substantially horizontal position the permanent magnet cooperates with the first switch and when the iron is in a substantially vertical position the permanent magnet cooperates with the second switch.
- the permanent magnet alternately cooperates with one or the other switch depending on the horizontal or vertical position of the iron.
- the first switch controls a timer circuit which initiates the cut off of the electrical supply to the iron after a predetermined time less than the time taken by the iron to reach its normal operating temperature.
- the second switch controls the other timer circuit which initiates the interruption of the electrical supply of the iron after a predetermined time greater than the time taken by the iron to reach its normal operating temperature.
- the predetermined time is short and considerably limits the risks of deterioration of the linen. Also when the iron is in the vertical position the predetermined time is long enough to allow the iron to reach its operating temperature.
- FIG. 1 shows the relative arrangements of the two switches 21, 22 and of the movable magnet 20.
- the latter is movable in rotation around the axis 23 along a circular path. It can therefore take position A when the iron is placed in a substantially horizontal position.
- the mobile magnet when the iron is in a substantially vertical position, due to the forces of gravity the mobile magnet always remains in the vertical position relative to the ground, but due to the tilting of the iron, the mobile magnet then comes to cooperate with the switch 22.
- This second situation is identified by the letter B and shown diagrammatically in dotted lines in FIG. 1.
- FIG. 2 represents the electrical diagram of the automatic safety device according to the invention which comprises the following essential elements: the flexible blade switches 21, 22, the movable magnet 20, a timer 30, a heating resistor 31 placed in the soleplate iron, a triac 32 controlling the energization of the heating resistor 31.
- the timer 30 is preferably the circuit whose reference is SAB529 manufactured by the company SIEMENS (RFA).

Abstract
Description
L'invention concerne un fer à repasser électrique muni d'un dispositif automatique de sécurité comportant un corps mobile, l'alimentation électrique du fer pouvant être coupée à l'aide du corps mobile soit par des premiers moyens de temporisation après un temps prédéterminé court, lorsque le fer est non utilisé en position horizontale, soit par des seconds moyens de temporisation après un temps prédéterminé long, lorsque le fer est non utilisé en position verticale.The invention relates to an electric iron fitted with an automatic safety device comprising a movable body, the electrical supply of the iron being able to be cut off using the movable body either by first time delay means after a short predetermined time. , when the iron is not used in the horizontal position, or by second time delay means after a long predetermined time, when the iron is not used in the vertical position.
Un fer à repasser peut donner lieu à certains problèmes lorsqu'après avoir été mis sous tension il est laissé immobile sur un tissu. Selon les températures atteintes le tissu peut être détérioré.An iron can give rise to certain problems when after being switched on it is left stationary on a cloth. Depending on the temperatures reached, the fabric can be damaged.
Un fer à repasser électrique muni d'un dispositif de sécurité qui évite ce genre de désagrément est connu du document GB 2 158 105.An electric iron fitted with a safety device which avoids this type of inconvenience is known from
Le dispositif électronique de sécurité est constitué d'un interrupteur à mercure qui coopère avec deux circuits de temporisation. Ceux-ci agissent lorsque le fer reste immobile l'un pour la position horizontale (temporisation de courte durée) et l'autre pour la position verticale du fer (temporisation de plus longue durée).The electronic safety device consists of a mercury switch which cooperates with two timing circuits. These act when the iron remains stationary, one for the horizontal position (short time delay) and the other for the vertical position of the iron (longer time delay).
Mais un tel fer à repasser présente des problèmes pour son utilisation. En effet l'interrupteur à mercure qui détecte les deux positions horizontale et verticale est constitué d'une goutte de mercure qui se déplace dans une ampoule munie de plots de contact. Cet interrupteur à mercure doit être monté avec une grande précision dans la poignée du fer à repasser avec une inclinaison de 5,5 ± 0,5 degrés. Ceci indique également que la même précision est requise pour assurer un bon fonctionnement du fer. Mais si le fer à repasser est posé sur un tissu avec des surépaisseurs faisant que la semelle n'est pas parfaitement horizontale, la bille de mercure ne fait alors plus le contact prévu dans le cylindre et tombe pour actionner la temporisation longue suffisante pour créer des dommages au tissu. On peut estimer qu'un angle de 5 degrés correspond approximativement à une surépaisseur de 2 cm entre les extrémités du fer à repasser. La tolérance de ± 0,5 degré indique donc qu'il suffit de peu de chose pour que le système soit mis en défaut. Le passage de l'une à l'autre des deux temporisations est donc mal contrôlé.But such an iron presents problems for its use. In fact, the mercury switch which detects the two horizontal and vertical positions consists of a drop of mercury which moves in a bulb fitted with contact pads. This mercury switch must be mounted with great precision in the handle of the iron with an inclination of 5.5 ± 0.5 degrees. This also indicates that the same precision is required to ensure proper functioning of the iron. But if the iron is placed on a fabric with extra thicknesses so that the sole is not perfectly horizontal, the mercury ball does not make the contact in the cylinder anymore and falls to activate the long time delay sufficient to create tissue damage. We can estimate that an angle of 5 degrees corresponds approximately to an extra thickness of 2 cm between the ends of the iron. The tolerance of ± 0.5 degree therefore indicates that little is enough for the system to be faulted. The passage from one to the other of the two timers is therefore poorly controlled.
Un des buts de l'invention est donc de remédier à ces conséquences néfastes qui peuvent entraîner une détérioration des linges.One of the aims of the invention is therefore to remedy these harmful consequences which can cause deterioration of the linen.
Pour cela l'invention telle que définie dans le préambule est remarquable en ce que le corps mobile est un aimant permanent qui, entre lesdites positions horizontale et verticale, se déplace en rotation autour d'un axe pour venir coopérer successivement avec deux commutateurs qui agissent respectivement sur les premiers et seconds moyens de temporisation.For this, the invention as defined in the preamble is remarkable in that the movable body is a permanent magnet which, between said horizontal and vertical positions, moves in rotation around an axis to come to cooperate successively with two switches which act respectively on the first and second timing means.
Préférentiellement l'aimant permanent est placé à l'extrémité d'une tige dont l'autre extrémité est montée sur un axe de rotation de sorte que l'aimant permanent et la tige forme un balancier. La longueur de la tige permet d'intervenir sur la précision de détection.Preferably, the permanent magnet is placed at the end of a rod, the other end of which is mounted on an axis of rotation, so that the permanent magnet and the rod form a pendulum. The length of the rod allows to intervene on the detection precision.
Les commutateurs sont constitués tous deux d'un interrupteur à lames souples qui coopèrent avec l'aimant permanent. Lorsque le fer à repasser est dans une position sensiblement horizontale l'aimant permanent coopère avec le premier commutateur et lorsque le fer à repasser est dans une position sensiblement verticale l'aimant permanent coopère avec le second commutateur. Ainsi l'aimant permanent coopère alternativement avec l'un ou l'autre commutateur selon la position horizontale ou verticale du fer à repasser.The switches both consist of a flexible reed switch which cooperates with the permanent magnet. When the iron is in a substantially horizontal position the permanent magnet cooperates with the first switch and when the iron is in a substantially vertical position the permanent magnet cooperates with the second switch. Thus the permanent magnet alternately cooperates with one or the other switch depending on the horizontal or vertical position of the iron.
Le premier commutateur contrôle un circuit temporisateur qui déclenche la coupure de l'alimentation électrique du fer après un temps prédéterminé inférieur au temps mis par le fer pour atteindre sa température normale de fonctionnement.The first switch controls a timer circuit which initiates the cut off of the electrical supply to the iron after a predetermined time less than the time taken by the iron to reach its normal operating temperature.
Egalement, le second commutateur contrôle l'autre circuit temporisateur qui déclenche la coupure de l'alimentation électrique du fer après un temps prédéterminé supérieur au temps mis par le fer pour atteindre sa température normale de fonctionnement.Also, the second switch controls the other timer circuit which initiates the interruption of the electrical supply of the iron after a predetermined time greater than the time taken by the iron to reach its normal operating temperature.
Ainsi lorsque le fer est dans la position horizontale le temps prédéterminé est court et limite considérablement les risques de détériorations des linges. Egalement lorsque le fer est dans la position verticale le temps prédéterminé est assez long pour permettre au fer d'atteindre sa température de fonctionnement.Thus when the iron is in the horizontal position the predetermined time is short and considerably limits the risks of deterioration of the linen. Also when the iron is in the vertical position the predetermined time is long enough to allow the iron to reach its operating temperature.
L'invention sera mieux comprise à l'aide des dessins donnés à titre d'exemples non limitatifs, et qui représentent:
- figure 1: la représentation de la disposition des deux interrupteurs à lames souples par rapport à l'aimant mobile,
- figure 2: un schéma électrique du dispositif automatique de sécurité selon l'invention.
- FIG. 1: the representation of the arrangement of the two flexible reed switches relative to the movable magnet,
- Figure 2: an electrical diagram of the automatic safety device according to the invention.
La figure 1 représente les dispositions relatives des deux interrupteurs 21, 22 et de l'aimant mobile 20. Celui-ci est mobile en rotation autour de l'axe 23 selon un trajet circulaire. Il peut donc prendre la position A lorsque le fer à repasser est mis dans une position sensiblement horizontale. Par contre lorsque le fer est en position sensiblement verticale, du fait des forces de pesanteur l'aimant mobile reste toujours dans la position verticale par rapport au sol, mais à cause du basculement du fer, l'aimant mobile vient alors coopérer avec l'interrupteur 22. Cette seconde situation est repérée par la lettre B et schématisée en pointillé sur la figure 1.FIG. 1 shows the relative arrangements of the two
La figure 2 représente le schéma électrique du dispositif automatique de sécurité selon l'invention qui comprend les éléments essentiels suivants: les interrupteurs à lames souples 21, 22, l'aimant mobile 20, un temporisateur 30, une résistance chauffante 31 placée dans la semelle du fer à repasser, un triac 32 contrôlant la mise sous tension de la résistance chauffante 31.FIG. 2 represents the electrical diagram of the automatic safety device according to the invention which comprises the following essential elements: the flexible blade switches 21, 22, the
Le temporisateur 30 est préférentiellement le circuit dont la référence est SAB529 fabriqué par la Société SIEMENS (RFA). Ce circuit SAB529 permet de regrouper dans un même boîtier les deux temporisations prédéterminées de courte et de longue durée. Il comprend une entrée START (broche 3) qui, lorsqu'elle est activée, démarre la temporisation courte, et une entrée multiplicatrice (broche 6) qui, lorsqu'elle est activée, multiplie la temporisation courte précédente par 10 afin d'obtenir la temporisation longue. La broche multiplicatrice 6 est connectée par l'intermédiaire d'une résistance 34 aux broches 7, 5 et 4 ainsi qu'à une entrée de l'interrupteur 22. Les broches 4, 5, 6 et 7 interviennent sur un coefficient multiplicateur des temps prédéterminés. La broche 6 est toujours au potentiel 0 volt lorsque l'interrupteur 22 est ouvert. L'autre entrée de l'interrupteur 22 est réunie à la broche 15 qui détermine le mode d'opération du triac. La broche START 3 est connectée à l'interrupteur à lames souples 21. Celui-ci est un interrupteur double de sorte que la lame souple mobile puisse entrer en contact avec deux bornes différentes 35, 36 selon que l'aimant 20 active ou non l'interrupteur 21. Les deux bornes 35, 36 sont reliées entre elles et connectées à la broche 3 du circuit 30. Lorsque la lame souple 37 est dans la position de passer de la borne 36 à la borne 35, ou inversement, elle se trouve être mise en l'air pendant un temps tel que l'autodémarrage de la temporisation peut s'opérer. La lame souple 37 est réunie à la broche 15 et à l'interrupteur 22. Une résistance 33 est placée entre les broches 1 et 3 de sorte que la broche 1 est toujours au potentiel V volts sauf lorsque l'interrupteur 21 est ouvert. Une capacité de filtrage 38 est placée entre les broches 1 et 18. Les broches 4, 5, 7 et 1 sont reliées entre elles, de même que les broches 9, 10, 11, 12 qui déterminent la durée des temps déterminés choisis (15 secondes dans l'exemple choisi).The timer 30 is preferably the circuit whose reference is SAB529 manufactured by the company SIEMENS (RFA). This SAB529 circuit allows the two predetermined short and long duration timers to be grouped in the same housing. It includes a START input (pin 3) which, when activated, starts the short time delay, and a multiplier input (pin 6) which, when activated, multiplies the previous short time delay by 10 in order to obtain the long time delay. The
Le mode de fonctionnement est le suivant. Lorsque le fer est placé dans la position sensiblement verticale l'interrupteur 22 est fermé et dès la mise en fonctionnement du circuit 30 la temporisation est activée pour une durée prédéterminée de par exemple 10 x 15 secondes = 150 secondes. Cette durée est suffisante pour permettre au fer d'atteindre sa température de fonctionnement. L'aimant 20 étant dans la position B, la lame souple 37 de l'interrupteur 21 est en contact avec la broche 36. Lorsque le fer est placé dans la position sensiblement horizontale, l'aimant 20 est dans la position A et la lame souple 37 est en contact avec la broche 35. L'interrupteur 22 est ouvert. A chaque mouvement du fer l'aimant mobile 20 effectue un mouvement de balancier qui ouvre le contact, puis le rétablit à chaque passage, entre la lame 37 et la broche 35. Cette succession d'interruptions effectue la remise à zéro de la temporisation. Celle-ci ne peut aller à son terme que si le fer cesse d'être déplacé. La temporisation est ainsi déclenchée au moment où la lame commune 37 de l'interrupteur est en l'air. Ainsi quelle que soit la position du fer, sauf bien sûr celle sensiblement verticale, la temporisation restera la temporisation minimale.The operating mode is as follows. When the iron is placed in the substantially vertical position, the
Un signal électrique correspondant à la temporisation courte ou à la temporisation longue est délivré sur la broche 16 qui est réunie à travers une résistance 39 à la gâchette du triac 32 mis en série avec la résistance chauffante 31. Ces deux derniers éléments étant reliés à la tension électrique du secteur aux bornes V et T. Entre la broche 2 et la borne T du secteur, sont connectées en série une résistance 40 et une diode 42. Une résistance 41 est connectée entre la broche 17 et la borne T, afin d'effectuer la synchronisation du triac.An electrical signal corresponding to the short time delay or to the long time delay is delivered on the
