Abstract

Level indicator for vacuum cleaner bag, consisting of a cylinder equipped with a visual indicator and containing a piston triggered by differential pressure, interacting with a traction spring, one side of which is linked to the atmosphere and the other side of which is linked to the depression chamber of the vacuum cleaner. The wall 8 of the cylinder comprises at least one bypass hole 9, which connects the depression side 10 of the cylinder 3 to the atmosphere.

Description

La présente invention concerne un indicateur de remplissage dc sac d'un aspirateur, constitue par un cylindre muni d'un voyant et contenant un piston commandé par la pression différentielle, interagissant avec un ressort de traction, dont ur côté est relié à l'atmosphère et dont l'entre ôté et relié à l'enceinte à dépressior de lçÒspirateur.  The present invention relates to an indicator for filling a vacuum cleaner bag, constituted by a cylinder provided with a sight glass and containing a piston controlled by differential pressure, interacting with a tension spring, whose side is connected to the atmosphere. and whose entry removed and connected to the vacuum chamber of the vacuum cleaner.

Dans des dispositifs indicateurs connus, un élément sensible, @il qu'un piston, est chargé par la diffé@ence de pression produite par le bloc moteur-soufflante de i aspirateur entre l'enceinte à depression et l'atmosphère. te piston se déplace contre la force exercée par un ressort à caractéristique linéaire et sa position instantanée est visible dans un voyant. Ces indicateurs présentent l'inconvénient suivant : lors de l'@@piration d'un tapis normal, le sace à poussière étant encore vide, le piston couvre déjà la moitié de la plage d'indication par suite c. la forte dépression.La plage résiduelle d'indication ne permet pF,- une lecture précise du niveau Xns..antané de remplissage du sac à poussière, car les divers paliers d'indication Sont de pltrs en plus ir; guliers quand le niveau de remplissage s'élève Il peut en résuier un remplacement prématuré du sac à poussière, d'où une augmenta; ion des coûts d'exploitation. In known indicating devices, a sensitive element, such as a piston, is charged by the pressure difference produced by the motor-blower unit of the vacuum cleaner between the vacuum chamber and the atmosphere. The piston moves against the force exerted by a spring with a linear characteristic and its instantaneous position is visible in a sight glass. These indicators have the following disadvantage: during the @@ piration of a normal carpet, the dust bag being still empty, the piston already covers half of the range of indication as a result c. the strong depression. The residual range of indication does not allow pF, - a precise reading of the level Xns..antaneous filling of the dust bag, because the various levels of indication Are more pltrs in addition ir; regular when the filling level rises It can result in premature replacement of the dust bag, hence an increase; ion of operating costs.

I1 arrive aussi que le sac à poussière soit remplacé trop tard, le moteur risquant d'erre détérioré par cuite d'un refroidissement insuf filant.  I1 also happens that the dust bag is replaced too late, the engine running the risk of being damaged due to insufficient cooling.

l'invention a pour objet un indi@@teur de remplissage du sac d'un aspirateur, évitant les indications errcnées et par suite un nettoyage prématuré ou tardif du récipient à poussière.  the subject of the invention is an indicator for filling the bag of a vacuum cleaner, avoiding erroneous indications and consequently premature or late cleaning of the dust container.

Selon une caractéristique essentielle de l'invention, la paroi au cylindre comporte au moins un trou df dérivation, qui relie le cC-té dépression du cylindre à l'atmospbêre.  According to an essential characteristic of the invention, the wall to the cylinder has at least one bypass hole, which connects the depression depression of the cylinder to the atmosphere.

Les trous de dérivation selon l'invention produisent une rentrée d'air du côté dépression du cylindre de l'indicateur de remplissage du sac, pendant le fonctionnement de l'aspirateur. L'indicateur de remplissage n'est pas chargé par la pleine dépression de l'aspirateur
Un ou plusieurs trous de dérivation sont réalisés de façon que le piston se déplace à peu près régulièrement, contre la force exercée par le ressort de traction, quand le remplissage du-sac à poussière augmente. La position de base du piston est déterminée par la dépression de l'aspirateur avec le sac à poussière entièrement vide.Par suite des trous de dérivation, le piston en position de base ne recouvre qu'une faible partie d'indication pendant le fonctionnement de l'aspirateur, de sorte que pratiquement toute la plage est disponible pour l'indication du remplissage; des indications erronées sont ainsi évitées à coup sur. Il n'y a donc plus de vidage prématuré ou tardif du récipient à poussière.
The bypass holes according to the invention produce an air intake on the vacuum side of the cylinder of the bag filling indicator, during the operation of the vacuum cleaner. The filling indicator is not charged by the full vacuum of the vacuum cleaner
One or more bypass holes are made so that the piston moves more or less regularly, against the force exerted by the tension spring, when the filling of the dust bag increases. The basic position of the piston is determined by the vacuum of the vacuum cleaner with the dust bag completely empty. As a result of the bypass holes, the piston in the basic position covers only a small part of the indication during operation of the the vacuum cleaner, so that practically the whole range is available for filling indication; erroneous indications are thus avoided for sure. There is therefore no longer any premature or late emptying of the dust container.

Un exemple de réalisation est décrit ci-dessous et représenté en coupe sur la figure unique. An exemplary embodiment is described below and shown in section in the single figure.

L'indicateur de remplissage du sac d'un aspirateur selon l1invention est constitué par un corps 1 avec un voyant 2 et un cylindre 3. The bag filling indicator of a vacuum cleaner according to the invention consists of a body 1 with a sight glass 2 and a cylinder 3.

Un piston 4 est mobile dans le cylindre 3, contre la force exercée par un ressort de traction 5. Un côté du piston 4 est relié à l'atmosphère par un trou 6 et l'autre côté est relié par une ouverture 7 à l'enceinte à dépression non représentée de l'aspirateur, contenant un sac à poussière. le ressort de traction 5 est fixé sur le piston 4 et le corps 1 de l'indicateur de remplissage. La paroi 8 du cylindre 3 comporte plusieurs trous de dérivation 9, qui relient le côté dépression 10 du cylindre 3 à l'atmosphère. Pendant l'aspiration, la pression du coté dépression 10, qui est fonction de la rentrée d'air et du degré de remplissage du sac à poussière, déplace le piston 4 à peu près régulièrement suivant le sens de la flèche, contre la force exercée par le ressort de traction 5. Ce mouvement du piston est visible dans le voyant 2 et permet de déterminer le degré instantané de remplissage du sac à poussière.A piston 4 is movable in the cylinder 3, against the force exerted by a tension spring 5. One side of the piston 4 is connected to the atmosphere by a hole 6 and the other side is connected by an opening 7 to the vacuum chamber not shown of the vacuum cleaner, containing a dust bag. the tension spring 5 is fixed on the piston 4 and the body 1 of the filling indicator. The wall 8 of the cylinder 3 has several bypass holes 9, which connect the vacuum side 10 of the cylinder 3 to the atmosphere. During suction, the pressure on the vacuum side 10, which is a function of the air intake and the degree of filling of the dust bag, moves the piston 4 approximately regularly in the direction of the arrow, against the force exerted by the tension spring 5. This movement of the piston is visible in the sight glass 2 and makes it possible to determine the instantaneous degree of filling of the dust bag.

Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art au principe et aux dispositifs qui viennent d'entre décrits uniquement à titre d'exemples non limitatifs, sans sortir du cadre de l'invention.  Of course, various modifications can be made by those skilled in the art to the principle and to the devices which come from described only by way of nonlimiting examples, without departing from the scope of the invention.
