Description

La présente invention a pour objet une machine à laver le linge.The present invention relates to a washing machine.

Une machine à laver comprend un châssis à l'intérieur duquel est montée une cuve contenant le tambour tournant. La cuve est suspendue à la partie supérieure du châssis à l'aide de ressorts hélicoïdaux, visant à amortir le déséquilibre se produisant lors de la rotation du tambour et du mouvement du linge à l'intérieur de celui-ci. Néanmoins, il est indispensable, notamment en période d'essorage où le déséquilibre dû à une répartition irrégulière du linge est le plus important, d'améliorer l'amortissement par friction de patins solidaires de la partie inférieure de la cuve dans des garnitures solidaires du châssis, et par le montage d'éléments de lestage sur la cuve renforçant la stabilité de celle-ci. Une autre solution consiste à utiliser un système de support et d'amortissement tel que décrit dans le brevet français 2 540 207.A washing machine comprises a frame inside which is mounted a tank containing the rotating drum. The tank is suspended from the upper part of the frame by means of helical springs, aimed at absorbing the imbalance occurring during the rotation of the drum and the movement of the linen inside it. Nevertheless, it is essential, especially during the spinning period when the imbalance due to an irregular distribution of the linen is the greatest, to improve the damping by friction of pads integral with the lower part of the tank in linings integral with the chassis, and by mounting ballast elements on the tank, reinforcing its stability. Another solution consists in using a support and damping system as described in French patent 2,540,207.

Les éléments de lestage d'une masse de 10 à 25 kg suivant la capacité de charge, la vitesse de rotation du tambour, et la qualité de la machine, sont constitués généralement par des pièces en fonte ou en béton comportant des inserts métalliques pour leur fixation sur la face extérieure de la cuve.Ballast elements with a mass of 10 to 25 kg depending on the load capacity, the drum rotation speed, and the quality of the machine, generally consist of cast iron or concrete parts with metal inserts for their fixing on the external face of the tank.

Il en résulte la nécessité de manipuler ces éléments de lestage à de nombreuses reprises, lors de l'approvisionnement en usine, de leur stockage, et de leur montage sur les machines. En outre, ils augmentent de façon sensible le poids des machines finies, ce qui rend plus difficile la manipulation de celles-ci lors des livraisons, dépannages, ou déménagements. En outre, le serrage de ces éléments se traduit parfois par des éclats d'émail sur la cuve. Enfin, compte tenu du volume de ces éléments, il n'est pas toujours possible de les monter aux emplacements les mieux adaptés, qui sont situés en partie haute et à l'arrière de la cuve.This results in the need to handle these ballast elements many times, during the supply to the factory, their storage, and their mounting on the machines. In addition, they significantly increase the weight of finished machines, which makes it more difficult to handle them during deliveries, repairs, or moves. Furthermore, the tightening of these elements sometimes results in fragments of enamel on the tank. Finally, given the volume of these elements, it is not always possible to mount them in the most suitable locations, which are located in the upper part and at the rear of the tank.

Il est connu par le document DE-A-1 902 325 de réaliser une machine à laver dans laquelle les éléments de lestage sont constitués par un réservoir de liquide disposé sur la paroi extérieure de la cuve.It is known from document DE-A-1 902 325 to produce a washing machine in which the ballasting elements consist of a liquid reservoir disposed on the external wall of the tank.

Le but de l'invention est de fournir une machine à laver possèdant, à vide, une masse réduite facilitant sa manipulation, dans laquelle le lest possède une valeur constante en conditions d'utilisation, et dans laquelle le lavage des tissus s'effectue dans les meilleures conditions thermiques.The object of the invention is to provide a washing machine having a vacuum, a reduced mass facilitating its handling, in which the ballast has a constant value under conditions of use, and in which the washing of fabrics is carried out in the best conditions thermal.

A cet effet, la machine à laver qu'elle concerne, du type comprenant une cuve qui, montée à l'intérieur d'un châssis, avec interposition d'éléments amortisseurs est équipée d'éléments de lestage constitués par au moins un réservoir de liquide, tel que de l'eau, disposé sur la paroi extérieure de la cuve, chaque réservoir étant équipé de moyens de remplissage et de vidange, est caractérisée en ce que chaque réservoir de lestage est monté en série sur le circuit d'alimentation en eau de la cuve qui débouche en partie basse de chaque réservoir, et en ce que chaque réservoir alimente, depuis sa partie supérieure et par déversement, la cuve directement, ou indirectement à travers une boîte à produits.To this end, the washing machine to which it relates, of the type comprising a tank which, mounted inside a chassis, with the interposition of damping elements, is fitted with ballasting elements constituted by at least one reservoir for liquid, such as water, disposed on the outer wall of the tank, each tank being equipped with filling and emptying means, is characterized in that each ballasting tank is mounted in series on the supply circuit in water from the tank which opens at the bottom of each tank, and in that each tank supplies, from its upper part and by pouring, the tank directly, or indirectly through a product box.

Cette solution est très intéressante car permettant de ne remplir les réservoirs de lestage que lorsque la machine se trouve sur son lieu d'utilisation ce qui facilite considérablement ses conditions de manutention. Il en résulte également une simplification et une amélioration des conditions de travail au niveau de l'approvisionnement et de la manipulation préalablement à la fabrication, puisque les éléments à manutentionner sont beaucoup plus légers que traditionnellement.This solution is very advantageous because it allows filling the ballast tanks only when the machine is at its place of use, which considerably facilitates its handling conditions. This also results in a simplification and an improvement in the working conditions in terms of supply and handling before manufacture, since the elements to be handled are much lighter than traditionally.

L'eau de lavage et l'eau de rinçage traversent d'abord le ou les réservoirs de lestage avant d'être déversée soit directement dans la cuve, soit dans la boîte contenant les produits de lavage, suivant le type de machine. Dès branchement de l'alimentation en eau de la machine, les réservoirs de lestage se remplissent automatiquement, sans nécessiter aucune opération spécifique. De plus, entre deux cycles de lavage, les réservoirs de lestage sont remplis d'eau qui prend la température supérieure à celle de l'eau du réseau, ce qui limite les dépenses de chauffage d'eau ultérieures. En outre, au cours d'un cycle de prélavage et de lavage, l'eau contenue dans les réservoirs est préchauffée, lors de l'opération de lavage qui précède son introduction dans la cuve, ce qui limite la consommation d'énergie de chauffage et évite l'introduction dans la cuve d'eau froide risquant de détériorer des articles textiles préalablement amenés à une température élevée.The washing water and rinsing water first pass through the ballast tank (s) before being discharged either directly into the tank or into the box containing the washing products, depending on the type of machine. As soon as the machine's water supply is connected, the ballast tanks are filled automatically, without requiring any specific operation. In addition, between two washing cycles, the ballast tanks are filled with water which takes the temperature higher than that of the mains water, which limits subsequent water heating expenses. In addition, during a prewash and washing cycle, the water contained in the tanks is preheated during the washing operation which precedes its introduction into the tank, which limits the consumption of heating energy. and avoids the introduction into the tank of cold water risking damaging textile articles previously brought to a high temperature.

Selon une première possibilité, l'électrovanne commandant l'amenée d'eau dans la cuve est disposée à l'extrémité du circuit d'amenée d'eau située en aval du ou des réservoirs de lestage.According to a first possibility, the solenoid valve controlling the supply of water to the tank is arranged at the end of the water supply circuit located downstream of the ballast tank or tanks.

Selon une autre possibilité, l'électrovanne commandant l'amenée d'eau dans la cuve est disposée à l'extrémité du circuit d'amenée d'eau située en amont du ou des réservoirs de lestage, et un clapet taré pour s'ouvrir à une pression légèrement inférieure à celle de l'eau du réseau est monté à l'extrémité aval du circuit d'amenée d'eau. Ce clapet qui s'ouvre en même temps que l'électrovanne évite que de l'eau contenue dans les réservoirs s'échappe de façon incontrôlée dans la cuve.Alternatively, the solenoid valve controlling the water supply to the tank is arranged at the end of the water supply circuit located upstream from the ballast tank (s), and a valve calibrated to open at a pressure slightly lower than that of the water network is mounted at the downstream end of the water supply circuit. This valve, which opens at the same time as the solenoid valve, prevents water contained in the tanks from escaping uncontrollably into the tank.

Avantageusement, le châssis est équipé en partie basse d'un réservoir monté en série avec le ou les réservoirs associés à la cuve.Advantageously, the chassis is equipped in the lower part with a tank mounted in series with the tank or tanks associated with the tank.

Le lestage ainsi obtenu de la partie basse du châssis améliore la stabilité de l'ensemble, tout en permettant de réaliser un allègement du châssis, ce qui est un facteur d'économie supplémentaire.The ballast thus obtained from the lower part of the chassis improves the stability of the assembly, while making it possible to lighten the chassis, which is an additional saving factor.

Selon une première forme d'exécution de cette machine à laver équipée d'une cuve en matière synthétique moulée, les réservoirs de lestage viennent de moulage avec la cuve.According to a first embodiment of this washing machine equipped with a molded plastic tank, the ballast tanks are molded with the tank.

Selon une autre forme d'exécution de cette machine à laver, les réservoirs de lestage sont réalisés indépendamment de la cuve et fixés sur la paroi extérieure de celle-ci. Ces réservoirs peuvent par exemple être réalisés en matière synthétique, tandis que la cuve est réalisée en acier. La localisation des différents réservoirs de lestage est fonction de la structure de la machine avec ouverture sur le dessus ou sur un côté et accès radial au tambour, ou sur le côté avec accès axial au tambour.According to another embodiment of this washing machine, the ballast tanks are produced independently of the tank and fixed to the external wall of the latter. These tanks can for example be made of synthetic material, while the tank is made of steel. The location of the different ballast tanks depends on the structure of the machine with opening on the top or on one side and radial access to the drum, or on the side with axial access to the drum.

Lorsque sont prévus plusieurs réservoirs qui ne communiquent pas directement entre eux, ils sont reliés par des tuyaux souples.When several tanks are provided which do not communicate directly with each other, they are connected by flexible pipes.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de cette machine à laver :

  • Figure 1 est une vue en perspective partiellement arrachée d'une première forme d'exécution de cette machine à laver ;
  • Figures 2 et 3 sont deux vues schématiques de côté partiellement arrachées de deux autres formes d'exécution de cette machine ;
  • Figure 4 est une vue de côté d'une forme d'exécution d'une cuve en matière synthétique ;
  • Figures 5 à 7 sont trois vues très schématiques correspondant à trois principes de fonctionnement d'une machine à laver ;
  • Figure 8 est une vue en coupe longitudinale d'un clapet anti-retour.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, representing, by way of nonlimiting examples, several embodiments of this washing machine:
  • Figure 1 is a partially broken away perspective view of a first embodiment of this washing machine;
  • Figures 2 and 3 are two schematic side views partially broken away from two other embodiments of this machine;
  • Figure 4 is a side view of an embodiment of a plastic tank;
  • Figures 5 to 7 are three very schematic views corresponding to three principles of operation of a washing machine;
  • Figure 8 is a longitudinal sectional view of a non-return valve.

La machine à laver représentée à la figure 1, comprend un châssis 2 à l'intérieur duquel est montée une cuve 3 de forme générale cylindrique contenant un tambour 4. La cuve 3 est montée suspendue sur le châssis par des ressorts 5, des éléments de friction 6 étant prévus à la partie inférieure de la cuve. Comme montré au dessin, l'entraînement du tambour 4 en rotation est réalisé par un moteur 7.The washing machine shown in Figure 1, includes a frame 2 inside which is mounted a tank 3 of generally cylindrical shape containing a drum 4. The tank 3 is mounted suspended on the chassis by springs 5, friction elements 6 being provided at the lower part of the tank. As shown in the drawing, the drum 4 is driven in rotation by a motor 7.

Dans la forme d'exécution représentée à la figure 1, l'accès au tambour est réalisé par une porte frontale 8 dans laquelle est logé le programmateur 9, l'ouverture de la porte 8 permettant le chargement et le déchargement du linge par une trappe débouchant radialement dans le tambour.In the embodiment shown in Figure 1, access to the drum is provided by a front door 8 in which is housed the programmer 9, the opening of the door 8 allowing the loading and unloading of laundry by a hatch opening radially into the drum.

Les figures 2 et 3 représentent deux variantes d'exécution de cette machine à laver dans lesquelles les mêmes éléments sont désignés par les mêmes références que précédemment, et dans lesquelles l'accès au tambour se fait par le dessus dans la forme d'exécution représentée à la figure 2, par une porte 10, et se fait latéralement et axialement au tambour par une porte 12, dans le cas de la machine de la figure 3.Figures 2 and 3 show two alternative embodiments of this washing machine in which the same elements are designated by the same references as above, and in which access to the drum is from above in the embodiment shown in FIG. 2, by a door 10, and is made laterally and axially to the drum by a door 12, in the case of the machine of FIG. 3.

Selon la caractéristique essentielle de l'invention, la cuve 3 est équipée d'éléments de lestage constitués par deux réservoirs d'eau 13 et 14 dans la forme d'exécution de la figure 1, 15 et 16 dans la forme d'exécution de la figure 2 et par un seul réservoir 17 dans la forme d'exécution de la figure 3.According to the essential characteristic of the invention, the tank 3 is equipped with ballasting elements constituted by two water tanks 13 and 14 in the embodiment of FIG. 1, 15 and 16 in the embodiment of FIG. 2 and by a single reservoir 17 in the embodiment of FIG. 3.

La disposition et la forme de ces réservoirs sont fonction de la masse de lestage désirée, du volume disponible entre le châssis et la cuve, et de la configuration de la machine et notamment de la localisation des ouvertures d'accès à l'intérieur du tambour.The arrangement and shape of these tanks are a function of the desired ballast mass, the volume available between the chassis and the tank, and the configuration of the machine and in particular the location of the access openings inside the drum. .

Comme montré à la figure 1, les réservoirs 13 et 14 sont alimentés en eau par une tubulure 18 qui constitue également la tubulure d'alimentation en eau de lavage et de rinçage. Les deux réservoirs 13 et 14 sont reliés l'un à l'autre par une tubulure 19.As shown in FIG. 1, the reservoirs 13 and 14 are supplied with water by a tube 18 which also constitutes the tube for supplying washing and rinsing water. The two tanks 13 and 14 are connected to each other by a tube 19.

Dans la forme d'exécution représentée à la figure 2, la machine est équipée en outre, d'un autre réservoir 20 disposé en partie basse du châssis, et destiné à assurer la stabilisation de l'ensembe, ce réservoir 20 étant monté sur le circuit d'alimentation en eau de la cuve, en amont des réservoirs 15 et 16.In the embodiment shown in Figure 2, the machine is further equipped with another tank 20 disposed in the lower part of the chassis, and intended to stabilize the assembly, this tank 20 being mounted on the circuit for supplying water to the tank, upstream of tanks 15 and 16.

Dans la forme d'exécution représentée à la figure 3, il est prévu un réservoir inférieur de lestage du châssis 22 et un seul réservoir de lestage de la cuve 17 disposé à la partie haute de celle-ci.In the embodiment shown in Figure 3, there is provided a lower ballast tank of the chassis 22 and a single ballast tank of the tank 17 disposed at the upper part thereof.

Comme montré aux figures 5 à 7, l'alimentation en eau est réalisée par une tubulure 18 branchée sur le réseau 23 avec interposition d'un robinet 24.As shown in Figures 5 to 7, the water supply is carried out by a tube 18 connected to the network 23 with interposition a tap 24.

Dans la forme d'exécution de la figure 5, l'électrovanne 25 d'alimentation en eau de la cuve, commandée par le programmateur, est montée sur la tubulure 18. A la figure 5 est également schématisé le moteur 26 et la tubulure 27 de vidange.In the embodiment of Figure 5, the solenoid valve 25 for supplying water to the tank, controlled by the programmer, is mounted on the pipe 18. In Figure 5 is also shown schematically the motor 26 and the pipe 27 drain.

Dans cette machine, l'alimentation en eau de la cuve se fait directement à partir de l'un des réservoirs de lestage. La machine, représentée à la figure 6, diffère de celle de la figure 5, au plan du principe, uniquement par le fait qu'est prévue une boîte 28 de distribution des produits de lavage dans laquelle est amenée l'eau de lavage et de rinçage.In this machine, the water supply to the tank is done directly from one of the ballast tanks. The machine, represented in FIG. 6, differs from that of FIG. 5, in terms of principle, only by the fact that there is provided a box 28 for dispensing washing products in which the washing and washing water is brought. rinsing.

Il est avantageux, lorsque l'électrovanne 25 est montée sur la tubulure 18 d'amenée d'eau, de disposer en aval du réservoir duquel s'échappe l'eau en direction de la cuve, un clapet anti-retour tel que celui 28 représenté à la figure 8, qui empêche, lorsque l'électrovanne 25 est fermée, l'eau contenue dans les réservoirs de s'échapper de façon non souhaitée dans la cuve.It is advantageous, when the solenoid valve 25 is mounted on the water supply pipe 18, to have downstream of the tank from which the water escapes in the direction of the tank, a non-return valve such as that 28 shown in Figure 8, which prevents, when the solenoid valve 25 is closed, the water contained in the tanks to escape unwanted into the tank.

Le clapet anti-retour 28 comprend un ressort 29 associé à un obturateur 30 pouvant venir en appui contre un siège 32 pour empêcher le passage de fluide lorsque la valeur de la pression d'eau est inférieure à la pression du ressort 29. La valeur de tarage du ressort 29 est légèrement inférieure à celle de la pression d'eau du réseau.The non-return valve 28 comprises a spring 29 associated with a shutter 30 which can come to bear against a seat 32 to prevent the passage of fluid when the value of the water pressure is lower than the pressure of the spring 29. The value of spring 29 setting is slightly lower than that of the network water pressure.

La figure 7 représente une variante d'exécution dans laquelle, l'électrovanne 25 est montée en aval du réservoir de lestage, juste avant la boîte à produits.FIG. 7 shows an alternative embodiment in which the solenoid valve 25 is mounted downstream of the ballast tank, just before the product container.

La figure 4 représente un mode de réalisation particulièrement intéressant d'une cuve 33 qui est obtenue par moulage avec quatre réservoirs 34 intégrés, un ensemble tubulaire comprenant la cuve proprement dite chacun des réservoirs et un fond venant de moulage, qui est ensuite obturé par un autre fond fixé par soudage haute fréquence ou ultrason.FIG. 4 represents a particularly interesting embodiment of a tank 33 which is obtained by molding with four integrated tanks 34, a tubular assembly comprising the tank itself each of the tanks and a bottom coming from molding, which is then closed by a other bottom fixed by high frequency welding or ultrasound.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant une machine à laver de conception simple comportant des éléments de lestage intégrés mais dont la masse n'intervient que lorsque cela est souhaitable, c'est-à-dire en période d'utilisation, les réservoirs de lestage pouvant être vidangés avant toute manipulation de la machine.As is apparent from the above, the invention brings a great improvement to the existing technique, by providing a washing machine of simple design comprising integrated ballasting elements but the mass of which intervenes only when desirable, it that is to say during the period of use, the ballast tanks can be drained before any manipulation of the machine.
