Abstract

A steam iron has a water tank which is connected to an evaporation chamber via a drip valve (4). The iron features an additional supply duct (7) between the water tank and the chamber. The duct (7) can be closed via a seal (8) which is mounted shiftably on the valve rod (6) of the drip valve (4)

Description

L'invention se rapporte à un fer à repasser à vapeur, comprenant uneThe invention relates to a steam iron, comprising a

semelle, une chambre d'évaporation et un réservoir d'eau qui est raccordé à cette dernière par une soupape d'égouttement.5 Dans les fers à repasser de ce type, la quantité d'eau nécessaire à la projection de vapeur est transférée goutte à goutte du réservoir d'eau dans la chambre d'évaporation chauffée électriquement. Ces fers à repasser ont l'inconvénient que du calcaire se dépose dans la chambre d'évaporation et dans les trous de sortie de vapeur que comporte la semelle et  soleplate, an evaporation chamber and a water tank which is connected to the latter by a drip valve. 5 In irons of this type, the quantity of water necessary for the projection of vapor is transferred drop drop from the water tank into the electrically heated evaporation chamber. These irons have the disadvantage that lime deposits in the evaporation chamber and in the steam outlet holes that the sole contains and

met le fer à repasser hors service avec le temps. Les dépôts de calcaire les plus importants se forment sur le fond de la chambre d'évaporation à l'emplacement de15 l'arrivée de l'égouttement.  puts the iron out of service over time. The most significant lime deposits form on the bottom of the evaporation chamber at the location of the arrival of the drip.

La présente invention a pour objet de créer un dispositif à l'aide duquel les dépôts de calcaire à  The object of the present invention is to create a device using which the lime deposits

l'intérieur de la semelle du fer à repasser sont éliminés de temps à autre.  the inside of the soleplate of the iron is removed from time to time.

Selon une particularité essentielle de l'invention, un canal complémentaire d'arrivée est prévu  According to an essential feature of the invention, a complementary arrival channel is provided

entre le réservoir d'eau et la chambre d'évaporation, il est obturable au moyen d'une garniture et celle-ci est montée déplaçable sur la tige de la soupape25 d'égouttement.  between the water tank and the evaporation chamber, it can be closed off by means of a gasket and the latter is movably mounted on the stem of the drip valve.

Conformément à l'invention, l'ouverture d'un canal complémentaire d'arrivée provoque brusquement l'évaporation d'une grande quantité d'eau dans la chambre correspondante et ainsi les couches de calcaire30 se trouvant dans la chambre d'évaporation et dans les trous de sortie de vapeur sont détachées. Il suffit avantageusement d'augmenter la longueur de la course de la tige de la soupape existante d'égouttement par une petite modification de la came de commande, de sorte que35 la fonction de cette soupape demeure conservée et qu'il est possible de modifier sans problème des fers à repasser à vapeur déjà existants. L'invention va être décrite plus en détail à titre d'exemple en regard des dessins annexés sur lesquels: la figure 1 est une coupe partielle verticale d'un fer à repasser à vapeur qui est équipé du dispositif selon l'invention; et la figure 2 illustre la partie du fer à repasser  According to the invention, the opening of a complementary inlet channel suddenly causes the evaporation of a large amount of water in the corresponding chamber and thus the layers of limestone 30 which are in the evaporation chamber and in the steam outlet holes are detached. It is advantageously sufficient to increase the length of the stroke of the rod of the existing drip valve by a small modification of the control cam, so that the function of this valve remains preserved and that it is possible to modify without problem of existing steam irons. The invention will be described in more detail by way of example with reference to the accompanying drawings in which: FIG. 1 is a partial vertical section of a steam iron which is equipped with the device according to the invention; and figure 2 illustrates the part of the iron

qui comporte la soupape de la figure 1.  which includes the valve of Figure 1.

La coupe partielle d'un fer à repasser à vapeur représenté à titre d'exemple illustre une partie de la semelle 1, la chambre d'évaporation 2, le réservoir d'eau 3 et la soupape d'égouttement 4. Celle-ci se15 compose d'un corps 5 et d'une tige 6. Un autre canal d'arrivée 7 qui est prévu à proximité du corps de soupape 5 raccorde le réservoir d'eau 3 à la chambre d'évaporation 2. Une garniture d'étanchéité 8 est montée déplaçable sur la tige 6 de la soupape à l'encontre de20 la pression d'un ressort 10 et elle obture le canal d'arrivée 7. Un élément d'entraînement 9 disposé sur la tige 6 de la soupape peut être mis par cette dernière en relation fonctionnelle avec la garniture 8. Si nécessaire, une grande quantité d'eau peut être projetée25 brusquement du réservoir 3 par le canal d'arrivée 7 dans la chambre 2 et y être évaporée de manière que les dépôts de calcaire soient détachés dans cette dernière et dans les trous 11 de sortie de vapeur d'eau. Il suffit à cette fin de faire monter la tige 6 de la30 soupape afin de soulever la garniture 8 au moyen de l'élément d'entraînement 9 contre la pression du ressort guidé sur cette tige pour ouvrir le canal 7. Le ressort 10 provoque le mouvement de rappel de la  The partial section of a steam iron shown by way of example illustrates part of the soleplate 1, the evaporation chamber 2, the water tank 3 and the drip valve 4. This is consists of a body 5 and a rod 6. Another inlet channel 7 which is provided near the valve body 5 connects the water tank 3 to the evaporation chamber 2. A seal 8 is movably mounted on the stem 6 of the valve against the pressure of a spring 10 and it closes the inlet channel 7. A drive element 9 disposed on the stem 6 of the valve can be put by the latter in functional relation with the lining 8. If necessary, a large amount of water can be thrown abruptly from the reservoir 3 through the inlet channel 7 into the chamber 2 and be evaporated therein so that the lime deposits are detached in the latter and in the holes 11 e steam outlet at. For this purpose, it suffices to raise the rod 6 of the valve in order to raise the lining 8 by means of the drive element 9 against the pressure of the spring guided on this rod to open the channel 7. The spring 10 causes the recall movement of the

garniture 8 en position de fermeture et il la tient35 aussi à cette position.  seal 8 in the closed position and it also holds it in this position.
