Description

La présente invention concerne un lave-linge à tambour horizontal à bain lessiviel en turbulence.The present invention relates to a washing machine with horizontal drum in a turbulent washing bath.

Dans un lave-linge connu à tambour horizontal, le tambour à linge comprend en général une surface intérieure cylindrique munie d'une ou plusieurs nervures longitudinales espacées rapportées ou formées in situ par pliage ou emboutissage qui permettent à une rotation de ce tambour, de soulever le linge et de le laisser retomber sous l'effet de son poids pour réaliser dans ce linge à la fois un brassage et une action mécanique de lavage, et une surface extérieure soit cylindrique et relativement lisse soit pourvue de creux longitudinaux constitués par des faces extérieures de ces nervures longitudinales intérieures.In a known washing machine with horizontal drum, the washing drum generally comprises a cylindrical interior surface provided with one or more spaced longitudinal ribs attached or formed in situ by folding or drawing which allow a rotation of this drum, to lift the laundry and to let it fall under the effect of its weight to achieve in this laundry both a stirring and a mechanical washing action, and an outer surface is cylindrical and relatively smooth or is provided with longitudinal recesses formed by outer faces of these interior longitudinal ribs.

Pendant un lavage, la cuve du lave-linge contient un bain lessiviel formé d'une quantité prédéterminée d'eau et d'une dose de produit lessiviel.During a wash, the washing machine tank contains a detergent bath formed by a predetermined quantity of water and a dose of detergent.

Dans ce bain lessiviel, est partiellement immergée la partie inférieure du tambour à linge. Lors de sa rotation, le tambour à linge créé une agitation dans les couches supérieures de ce bain lessiviel et laisse pratiquement sans amples mouvements les couches inférieures de ce bain qui sont confinées dans un fond en creux de la cuve de ce lave-linge où vient se déposer ou s'accumuler la partie non encore dissoute de la dose de lessive introduite. Cette partie de lessive non dissoute se trouve ainsi à l'abri, ne participe pas au lavage du linge, s'évacue en pure perte lors d'une vidange de la cuve de ce lave-linge et entraîne un mauvais résultat de lavage.The lower part of the washing drum is partially submerged in this washing bath. During its rotation, the laundry drum creates agitation in the upper layers of this washing bath and leaves practically without large movements the lower layers of this bath which are confined in a hollow bottom of the tank of this washing machine where deposit or accumulate the not yet dissolved part of the detergent dose introduced. This part of undissolved detergent is thus sheltered, does not participate in washing the laundry, is evacuated as a pure waste during an emptying of the tank of this washing machine and results in a poor washing result.

Des solutions connues ont été proposées pour éviter cette perte de lessive et ce mauvais résultat de lavage. Une de ces solutions consiste à faire tourner périodiquement la pompe de vidange de l'appareil au cours d'une phase de lavage pour créer une turbulence dans les couches inférieures du bain de lessive dans le fond de la cuve du lave-linge et forcer de ce fait la lessive qui s'y accumule à se dissoudre intégralement et à participer au lavage du linge. Cette solution connue donne de bons résultats mais exige une programmation spécifique du fonctionnement du lave-linge et entraîne une mise en marche fréquente et par conséquent une usure prématurée de la pompe de vidange.Known solutions have been proposed to avoid this loss of detergent and this poor washing result. One of these solutions consists in periodically turning the drain pump of the appliance during a washing phase to create turbulence in the lower layers of the detergent bath at the bottom of the washing machine tub and thereby force the detergent that accumulates there to dissolve completely and participate in washing the laundry. This known solution gives good results but requires specific programming of the operation of the washing machine and results in frequent starting and therefore premature wear of the drain pump.

Une autre solution connue consiste à obturer, dans le fond de la cuve la partie en creux profond donnant accès à la pompe de vidange quand cette pompe est à l'arrêt. Cette solution empêche la partie non encore dissoute de la dose de lessive introduite dans la cuve du lave-linge, de venir s'accumuler et de rester à l'abri dans cette partie en creux profond.Another known solution consists in closing, in the bottom of the tank, the deep recess giving access to the drain pump when this pump is stopped. This solution prevents the not yet dissolved part of the dose of detergent introduced into the washing machine's tank from accumulating and staying sheltered in this deep hollow part.

Toutefois, une obturation de cette partie en creux profond donnant accès à la pompe de vidange ne conduit pas à une création, dans le bain lessiviel dans le fond de la cuve du lave-linge, d'une turbulence qui force une dissolution intégrale de la partie de lessive non dissoute et une participation de celle-ci au lavage du linge.However, closing off this deep recess giving access to the drain pump does not lead to the creation, in the detergent bath at the bottom of the washing machine tank, of turbulence which forces the complete dissolution of the part of undissolved detergent and its participation in washing the laundry.

La présente invention ayant pour but d'éviter les inconvénients ci-dessus, permet de réaliser un lave-linge à tambour horizontal qui créé une turbulence dans le bain lessiviel aussi bien au niveau du fond ou partie inférieure en creux de la cuve qu'au niveau des couches supérieures de ce bain.The aim of the present invention is to avoid the above drawbacks, which makes it possible to produce a washing machine with a horizontal drum which creates turbulence in the detergent bath both at the level of the bottom or lower hollow part of the tank and at level of the upper layers of this bath.

Cette turbulence entraîne une dissolution intégrale de la partie de lessive non encore dissoute qui s'accumule dans le fond de la cuve, et par conséquent une participation active de cette partie de cette lessive, au lavage du linge.This turbulence leads to an integral dissolution of the part of detergent not yet dissolved which accumulates in the bottom of the tank, and consequently an active participation of this part of this detergent, in washing the laundry.

Selon l'invention, un lave-linge horizontal pourvu de nervures intérieures de brassage et lavage du linge est caractérisé en ce que le tambour à linge comprend, sur son pourtour, des pales génératrices de turbulence, angulairement espacées, et apparentes sur sa surface extérieure.According to the invention, a horizontal washing machine provided with internal ribs for stirring and washing the laundry is characterized in that the laundry drum comprises, around its periphery, blades generating turbulence, angularly spaced, and visible on its outer surface .

Pour mieux faire comprendre l'invention, on en décrit ci-après un certain nombre d'exemples de réalisation illustrés par des dessins ci-annexé dont :

  • - la figure 1 représente une vue partielle, schématique, en coupe d'un lave-linge à tambour horizontal montrant un tambour selon un premier exemple de réalisation, pourvu de nervures intérieures de brassage et lavage et de pales génératrices de turbulence ;
  • - la figure 2 représente à une autre échelle, une vue en plan de la face extérieure d'un ensemble nervure de brassage et lavage et pale génératrice de turbulence selon une première variante de réalisation du tambour du lave-linge de la figure 1, et
  • - la figure 3 représente à une autre échelle, une vue en plan de la face extérieure d'un ensemble nervure de brassage et lavage et pale génératrice de turbulence selon une deuxième variante de réalisation du tambour du lave-linge de la figure 1.
To better understand the invention, a number of embodiments are described below, illustrated by the attached drawings, including:
  • - Figure 1 shows a partial schematic view in section of a washing machine with horizontal drum showing a drum according to a first embodiment, provided with internal brewing and washing ribs and blades generating turbulence;
  • FIG. 2 represents, on another scale, a plan view of the external face of a stirring and washing rib assembly and a turbulence generating blade according to a first embodiment of the drum of the washing machine of FIG. 1, and
  • - Figure 3 shows on another scale, a plan view of the outer face of a mixing and washing rib assembly and blade generating turbulence according to a second alternative embodiment of the drum of the washing machine of Figure 1.

Un lave-linge 1 selon un exemple de réalisation illustré partiellement et schématiquement dans la figure 1 comprend une carrosserie 2 indiquée en traits mixtes, une cuve 3, un tambour cylindrique à linge 4 tournant autour d'un axe horizontal 5. Le tambour à linge 4 est pourvu sur sa surface cylindrique intérieure, de nervures longitudinales intérieures, angulairement espacées 8. Ces nervures 8 sont destinées à soulever le linge se trouvant à l'intérieur de ce tambour 4 lors d'une rotation de ce tambour et le laisser tomber sous l'effet de son poids pour réaliser à la fois un brassage de la masse de ce linge et une action mécanique de lavage de ce linge indépendamment d'une action chimique de lavage effectuée par un produit lessiviel introduit dans la cuve 3 et dissous dans une eau 9 pour former un bain lessiviel 11 qui recouvre une partie inférieure de la cuve 3 et une partie du tambour 4.A washing machine 1 according to an exemplary embodiment partially and schematically illustrated in FIG. 1 comprises a bodywork 2 indicated in phantom, a tank 3, a cylindrical laundry drum 4 rotating around a horizontal axis 5. The laundry drum 4 is provided on its inner cylindrical surface with internal longitudinal angularly spaced ribs 8. These ribs 8 are intended to lift the laundry located inside this drum 4 during rotation of this drum and drop it under the effect of its weight to achieve both a mixing of the mass of this laundry and a mechanical action of washing this laundry independently of a chemical washing action carried out by a detergent introduced into the tank 3 and dissolved in a water 9 to form a detergent bath 11 which covers a lower part of the tank 3 and a part of the drum 4.

La cuve 3 comprend dans sa partie inférieure un fond 10 en creux profond donnant accès à une pompe de vidange 12, schématiquement représentée en traits discontinus. Lors d'une introduction d'une dose de produit lessiviel dans la cuve 3, à travers une entrée 14, une grande partie de cette dose de produit se dissolve en traversant la masse d'eau 9 et forme un bain lessiviel 11. Une faible partie de cette dose de produit non encore dissoute atteint le fond 10 de la cuve 3 et se dépose dans le creux de ce fond. Si aucune turbulence n'est produite dans ce bain lessiviel 11 au niveau de ce fond 10 de la cuve 3, cette partie de produit lessiviel qui s'y trouve reste non dissoute et sera évacuée en pure perte lors d'une vidange de la cuve 3 par la pompe 12.The tank 3 comprises in its lower part a bottom 10 deep recess giving access to a drain pump 12, schematically shown in broken lines. When introducing a dose of detergent into tank 3, through an inlet 14, a large part of this dose of product dissolves by crossing the body of water 9 and forms a detergent bath 11. A small part of this dose of product not yet dissolved reaches the bottom 10 of the tank 3 and is deposited in the hollow of this bottom. If no turbulence is produced in this detergent bath 11 at the level of this bottom 10 of the tank 3, this part of detergent product which is there remains undissolved and will be evacuated in pure loss during an emptying of the tank 3 by pump 12.

Selon l'invention, un lave-linge 1 à tambour horizontal 4 pourvu de nervures intérieures de brassage et lavage du linge 8 est caractérisé en ce que le tambour à linge 4 comprend sur son pourtour des pales génératrices de turbulence 15, angulairement espacées et apparentes sur sa surface extérieure.According to the invention, a washing machine 1 with a horizontal drum 4 provided with internal ribs for stirring and washing the laundry 8 is characterized in that the laundry drum 4 includes, around its periphery, turbulence-generating blades 15, angularly spaced and visible on its outer surface.

Lors d'une rotation, le tambour à linge 4 avec ses nervures intérieures de brassage et lavage 8 créent une agitation dans les couches supérieures du bain lessiviel 11 tandis que les pales 15 de ce tambour 4 engendrent une intense turbulence dans les couches inférieures de ce bain lessiviel 11 qui se trouvent au niveau du fond 10 en creux de la cuve 3. Cette intense turbulence déloge la partie de produit lessiviel non encore dissoute qui s'y trouve, la soulève dans ce bain 11 et la force à se dissoudre intégralement et à participer activement à l'action chimique de lavage du linge. La dose de produit lessiviel introduite dans la cuve 3 est ainsi complètement dissoute et participe dans sa totalité à l'action chimique de lavage du linge. Aucune perte inutile de lessive non dissoute habituellement retrouvée dans des lave-linge connus n'est ainsi enregistrée. Une dose de produit lessiviel habituellement prévue pour un lavage dans un lave-linge connu peut être ainsi avantageusement réduite d'une manière appréciable en cas d'un lavage du linge dans un lave-linge réalisé selon l'invention et sans compromettre un bon résultat souhaité de lavage. Par ailleurs, un bain lessiviel en agitation avec un produit lessiviel bien dissous augmente son effet mouillant, étend son action chimique de lavage dans toute la masse de ce linge et donne un meilleur résultat de lavage du linge que celui habituellement obtenu dans des lave-linge connus.During a rotation, the laundry drum 4 with its internal mixing and washing ribs 8 creates agitation in the upper layers of the detergent bath 11 while the blades 15 of this drum 4 generate intense turbulence in the lower layers of this detergent bath 11 which are located at the bottom 10 in the hollow of the tank 3. This intense turbulence dislodges the part of detergent not yet dissolved therein, lifts it up in this bath 11 and forces it to dissolve completely and actively participate in the chemical action of washing clothes. The dose of detergent introduced into the tank 3 is thus completely dissolved and participates in its entirety in the chemical action of washing the laundry. No unnecessary loss of undissolved detergent usually found in known washing machines is thus recorded. A dose of detergent usually provided for washing in a known washing machine can thus be advantageously reduced appreciably in the case of washing the laundry in a washing machine produced according to the invention and without compromising a good result desired wash. In addition, a shaking detergent bath with a well-dissolved detergent increases its wetting effect, extends its chemical washing action throughout the mass of this laundry and gives a better washing result than that usually obtained in known washing machines.

Dans l'exemple de réalisation illustré à la figure 1, le tambour à linge 4 comprend une virole ou paroi latérale constituée par une feuille métallique munie de perforations et d'ouvertures non représentées enroulées en cylindre et dans laquelle des nervures longitudinales intérieures de brassage et lavage 8 sont directement formées par pliage. Les nervures 8 font ainsi partie intégrante de cette virole et le tambour 4 présente vers l'extérieur une paroi latérale munie de creux longitudinaux espacés qui sont des faces extérieures de ces nervures longitudinales intérieures de brassage et lavage 8.In the embodiment illustrated in FIG. 1, the laundry drum 4 comprises a ferrule or side wall constituted by a metal sheet provided with perforations and not shown openings wound in a cylinder and in which internal longitudinal ribs for mixing and washing 8 are directly formed by folding. The ribs 8 thus form an integral part of this ferrule and the drum 4 presents towards the outside a side wall provided with spaced longitudinal recesses which are external faces of these internal longitudinal brewing and washing ribs 8.

Dans les exemples illustrés, les pales génératrices de turbulence sous forme de plaques planes 15, 18 ou sous forme de feuilles ondulées 23 ou pliées en zigzag, sont radialement formées dans des creux longitudinaux de la virole du tambour constitués par des faces extérieures des nervures de brassage et lavage 8, et suivant l'axe de ces creux. Ces pales sont, soit des parties intégrantes de ces nervures 8, soit rapportées et fixées par soudage, collage, vissage, rivetage, emboîtage, ou tout autre moyen connu de fixation sur les faces extérieures en creux de ces nervures 8.In the examples illustrated, the turbulence-generating blades in the form of flat plates 15, 18 or in the form of corrugated sheets 23 or folded in a zigzag shape, are radially formed in longitudinal recesses of the drum shell constituted by the external faces of the ribs of stirring and washing 8, and along the axis of these hollows.
