Description

La présente invention concerne un réservoir d'eau de lavage et/ou de rinçage d'une machine à laver.The present invention relates to a water tank for washing and / or rinsing a washing machine.

Elle concerne également une machine à laver comprenant un réservoir d'eau de lavage et/ou de rinçage, et en particulier une machine à laver le linge ou une machine à laver la vaisselle.It also relates to a washing machine comprising a wash water tank and / or rinse, and in particular a washing machine or a dishwashing machine.

De manière générale, la présente invention concerne les machines à laver comprenant un réservoir d'eau de lavage et/ou de rinçage permettant l'utilisation de cette eau de lavage et/ou de rinçage au cours d'une phase suivante d'un cycle de fonctionnement ou lors d'un cycle de fonctionnement suivant.In general, the present invention relates to washing machines comprising a wash water tank and / or rinse allowing the use of this washing water and / or rinse during a subsequent phase of a cycle operation or during a subsequent operating cycle.

Plus particulièrement, la présente invention trouve son application dans les machines à laver domestiques, et en particulier dans les machines à laver le linge et les machines à laver la vaisselle.More particularly, the present invention finds its application in domestic washing machines, and in particular in washing machines and dishwashing machines.

On connaît déjà des machines à laver comprenant une cuve de lavage, un réservoir d'eau de lavage et/ou de rinçage, et un circuit hydraulique de distribution d'eau. Le circuit hydraulique de distribution d'eau relie la cuve de lavage au réservoir d'eau au moyen de conduites de circulation d'eau souples.Washing machines are already known comprising a washing tank, a washing and / or rinsing water tank, and a hydraulic water distribution circuit. The water distribution hydraulic circuit connects the wash tub to the water tank by means of flexible water circulation lines.

Au cours de l'utilisation de la machine à laver, le réservoir d'eau peut être soumis à des efforts tendant à le déformer.During the use of the washing machine, the water tank may be subjected to efforts tending to deform it.

Cependant, ces machines à laver présentent l'inconvénient que la rigidité du réservoir d'eau est assurée seulement par les parois du réservoir d'eau. Du fait de la hauteur importante du réservoir d'eau, la surface des parois du réservoir d'eau est grande.However, these washing machines have the disadvantage that the rigidity of the water tank is provided only by the walls of the water tank. Due to the large height of the water tank, the surface of the walls of the water tank is large.

Par conséquent, lors du transport et/ou de l'utilisation de la machine à laver, le réservoir d'eau risque de se déformer sous l'effet d'efforts appliqués sur les parois externes du réservoir d'eau par des objets ou des personnes, ou sous l'effet d'efforts exercés sur le réservoir d'eau par le liquide qu'il contient.Therefore, during transport and / or use of the washing machine, the water tank may deform under the effect of forces applied to the outer walls of the water tank by objects or objects. people, or under the effect of forces exerted on the water tank by the liquid it contains.

Les efforts appliqués sur une paroi du réservoir d'eau par des objets ou des personnes peuvent déformer la paroi du réservoir d'eau en l'enfonçant vers l'intérieur du réservoir d'eau.The forces applied to a wall of the water tank by objects or persons may deform the wall of the water tank by pushing it into the water tank.

L'enfoncement d'une paroi du réservoir d'eau vers l'intérieur de celui-ci peut réduire la contenance du réservoir d'eau.Depressing a wall of the water reservoir into the interior of the water reservoir can reduce the capacity of the water reservoir.

Les efforts exercés sur le réservoir d'eau par le liquide qu'il contient peuvent déformer le réservoir d'eau en le faisant gonfler.The forces exerted on the water tank by the liquid it contains can deform the water tank by causing it to swell.

La déformation des parois du réservoir d'eau sous l'effet des efforts exercés par le liquide qu'il contient déforme les parois du réservoir d'eau vers l'extérieur de celui-ci.The deformation of the walls of the water tank under the effect of the forces exerted by the liquid it contains deforms the walls of the water tank to the outside thereof.

De telles déformations des parois du réservoir d'eau peuvent également provoquer des dysfonctionnements des composants embarqués sur le réservoir d'eau ou disposés à proximité de celui-ci, par exemple en créant des fuites au niveau des raccordements de ces composants sur le réservoir d'eau.Such deformations of the walls of the water tank may also cause malfunctions of the components on board the water tank or disposed near it, for example by creating leaks at the connections of these components on the water tank.

Les efforts qui génèrent des déformations du réservoir d'eau créent des contraintes sur le réservoir d'eau qui peuvent l'endommager.Efforts that generate deformations of the water tank create stresses on the water tank that can damage it.

Les déformations consécutives à des efforts reçus par le réservoir d'eau peuvent engendrer une modification de la géométrie globale du réservoir d'eau ainsi que désolidariser le réservoir d'eau de la machine à laver et libérer des éléments d'encliquetage servant à fixer le réservoir d'eau sur la machine à laver.The deformations resulting from forces received by the water tank may cause a modification of the overall geometry of the water tank as well as disconnect the water tank from the washing machine and release snap-fastening elements for fixing the water tank. water tank on the washing machine.

On connaît également le document FR 2 951 469 A1 qui décrit un réservoir d'eau de lavage et/ou de rinçage pour une machine à laver, ledit réservoir d'eau comprenant deux parois en forme de coque, où une première paroi est disposée en vis-à-vis d'une deuxième paroi, et où les deux parois sont assemblées ensemble.The document is also known FR 2 951 469 A1 which describes a washing and / or rinsing water tank for a washing machine, said water tank comprising two shell-shaped walls, wherein a first wall is disposed opposite a second wall , and where the two walls are assembled together.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un réservoir d'eau de lavage et/ou de rinçage, ainsi qu'une machine à laver, permettant de minimiser le risque de déformation du réservoir d'eau lors du transport et de l'utilisation de la machine à laver.The present invention aims to solve the aforementioned drawbacks and to provide a wash water tank and / or rinse, and a washing machine, to minimize the risk of deformation of the water tank during transport and the use of the washing machine.

A cet égard, la présente invention vise, selon un premier aspect, un réservoir d'eau de lavage et/ou de rinçage pour une machine à laver, ledit réservoir d'eau comprenant :

  • deux parois en forme de coque,
    • où une première paroi est disposée en vis-à-vis d'une deuxième paroi, et
    • où les deux parois sont assemblées ensemble.
In this regard, the present invention aims, in a first aspect, a washing water tank and / or rinse for a washing machine, said water tank comprising:
  • two hull-shaped walls,
    • wherein a first wall is disposed opposite a second wall, and
    • where the two walls are assembled together.

Selon l'invention, ledit réservoir d'eau comprend également :

  • des moyens de renforcement ménagés dans au moins l'une des deux parois du réservoir d'eau et s'étendant entre les deux parois du réservoir d'eau de sorte à maintenir l'écartement entre les deux parois.
According to the invention, said water reservoir also comprises:
  • reinforcement means provided in at least one of the two walls of the water tank and extending between the two walls of the water tank so as to maintain the spacing between the two walls.

Ainsi, lorsque des efforts sont appliqués sur une des deux parois du réservoir d'eau, l'écartement entre les deux parois du réservoir d'eau de lavage et/ou de rinçage d'une machine à laver est maintenu grâce aux moyens de renforcement.Thus, when forces are applied to one of the two walls of the water tank, the spacing between the two walls of the washing and / or rinsing water tank of a washing machine is maintained by the reinforcing means. .

D'une part, lors du transport et/ou de l'utilisation de la machine à laver, les déformations des parois du réservoir d'eau vers l'intérieur de celui-ci du fait d'efforts appliqués sur une paroi du réservoir d'eau par des objets ou des personnes peuvent être empêchés.On the one hand, during the transport and / or use of the washing machine, the deformations of the walls of the water tank towards the inside thereof due to forces applied to a wall of the water tank. water through objects or people can be prevented.

De plus, le risque de réduction de la contenance du réservoir d'eau est évité grâce aux moyens de renforcement qui font obstacle à une réduction de l'écartement entre les deux parois du réservoir d'eau.In addition, the risk of reducing the capacity of the water tank is avoided by means of reinforcement that hinder a reduction in the spacing between the two walls of the water tank.

D'autre part, les moyens de renforcement peuvent s'opposer à l'augmentation de l'écartement entre les deux parois du réservoir d'eau. Ainsi, des efforts internes au réservoir d'eau et s'appliquant en direction de ses parois ne génèrent pas de déformations des parois du réservoir d'eau. De cette façon, le gonflement du réservoir d'eau du fait des efforts exercés sur les parois du réservoir d'eau par le liquide qu'il contient est empêché.On the other hand, the means of reinforcement can oppose the increase of the distance between the two walls of the water tank. Thus, internal forces in the water tank and applying in the direction of its walls do not generate deformations of the walls of the water tank. In this way, the swelling of the water tank due to the forces exerted on the walls of the water tank by the liquid it contains is prevented.

Les moyens de renforcement rigidifient le réservoir d'eau et empêchent les déformations des parois du réservoir d'eau. En particulier, les zones de raccordement des composants embarqués sur le réservoir d'eau ne se déforment pas. Grâce à cette rigidité du réservoir d'eau, les risques de fuite, ainsi que les dysfonctionnements qui en découlent pour les composants embarqués ou situés à proximité, sont évités.The reinforcing means stiffen the water tank and prevent deformation of the walls of the water tank. In particular, the connection areas of the components on board the water tank do not deform. Thanks to this rigidity of the water tank, the risks of leakage, as well as the resulting malfunctions for embedded components or located nearby, are avoided.

Les efforts appliqués aux parois du réservoir d'eau sont supportés par les moyens de renforcement du réservoir d'eau. Ainsi, les déformations des parois du réservoir d'eau, et les dommages consécutifs potentiels au réservoir d'eau, sont empêchés.The forces applied to the walls of the water tank are supported by the means for reinforcing the water tank. Thus, the deformations of the walls of the water tank, and the consequent potential damage to the water tank, are prevented.

Le réservoir d'eau, ainsi rigidifié par des moyens de renforcement ménagés dans au moins l'une de ses deux parois, conserve en permanence sa géométrie globale initiale, indépendamment des efforts qui lui sont appliqués. De cette façon, le risque de voir le réservoir d'eau se désolidariser de la machine à laver est écarté. En particulier, les moyens de renforcement du réservoir d'eau assure que des éléments d'encliquetage servant à fixer le réservoir d'eau sur la machine à laver restent en prise.The water tank, thus stiffened by reinforcement means provided in at least one of its two walls, permanently retains its initial overall geometry, independently of the forces applied to it. In this way, the risk of the water tank becoming disconnected from the washing machine is discarded. In particular, the means for reinforcing the water tank ensures that detent elements for fixing the water tank on the washing machine remain in engagement.

Pratiquement, le réservoir d'eau est un réservoir de récupération et de stockage d'eau de lavage et/ou de rinçage pour une réutilisation de l'eau de lavage et/ou de rinçage au cours d'une phase suivante d'un cycle de fonctionnement ou lors d'un cycle de fonctionnement suivant de la machine à laver.Practically, the water tank is a tank for the recovery and storage of washing and / or rinsing water for reuse of the washing and / or rinsing water during a subsequent phase of a cycle. of operation or during a subsequent operating cycle of the washing machine.

La présente invention vise, selon un deuxième aspect, une machine à laver, en particulier une machine à laver le linge ou une machine à laver la vaisselle, comprenant un réservoir d'eau de lavage et/ou de rinçage conforme à l'invention.The present invention aims, in a second aspect, a washing machine, in particular a washing machine or a dishwashing machine, comprising a washing water tank and / or rinse according to the invention.

Cette machine à laver présente des caractéristiques et avantages analogues à ceux décrits précédemment en relation avec le réservoir d'eau de lavage et/ou de rinçage selon l'invention.This washing machine has characteristics and advantages similar to those described above in connection with the washing water tank and / or rinse according to the invention.

Préférentiellement, le réservoir d'eau de lavage et/ou de rinçage 6 est interne à la carrosserie 2 de la machine à laver le linge 1.Preferably, the washing and / or rinsing water tank 6 is internal to the body 2 of the washing machine 1.

Le réservoir d'eau de lavage et/ou de rinçage 6 peut être fixé sur la carrosserie 2 de la machine à laver le linge 1, par exemple sur une paroi de la carrosserie 2, telle que la paroi avant 2a, la paroi arrière 2b ou une paroi latérale 2e.The washing and / or rinsing water tank 6 can be fixed to the body 2 of the washing machine 1, for example on a wall of the body 2, such as the front wall 2a, the rear wall 2b. or a side wall 2e.

Bien entendu, le positionnement et/ou la fixation du réservoir d'eau de lavage et/ou de rinçage avec la carrosserie de la machine à laver ne sont nullement limitatifs et peuvent être différents.Of course, the positioning and / or attachment of the wash water tank and / or rinse with the body of the washing machine are in no way limiting and may be different.

La machine à laver le linge 1 comprend un circuit hydraulique de distribution d'eau, où le circuit hydraulique de distribution d'eau relie la cuve de lavage 3 de la machine à laver le linge 1 au réservoir d'eau 6.The washing machine 1 comprises a hydraulic water distribution circuit, wherein the hydraulic water distribution circuit connects the washing tub 3 of the washing machine 1 to the water tank 6.

La machine à laver le linge 1 peut comprendre une alimentation en eau du réseau (non représentée) de sorte à remplir la cuve de lavage 3 lors des différentes phases d'un cycle de lavage avec de l'eau n'ayant pas été utilisée lors d'une phase précédente du cycle de fonctionnement en cours ou lors d'un cycle de fonctionnement précédent.The washing machine 1 may comprise a water supply network (not shown) so as to fill the washing tub 3 during the different phases of a wash cycle with water that was not used during from a previous phase of the current operating cycle or during a previous operating cycle.

Le circuit hydraulique de distribution d'eau comprend au moins une pompe de circulation d'eau 11 de sorte à remplir en eau de lavage et/ou de rinçage le réservoir d'eau 6 depuis la cuve de lavage 3 de la machine à laver le linge 1.The hydraulic water distribution circuit comprises at least one water circulation pump 11 so as to fill the water tank 6 with washing water and / or rinsing water from the washing tub 3 of the washing machine. linen 1.

Avantageusement, au moins une pompe de circulation d'eau 11, 12 du circuit hydraulique de distribution d'eau permet de mettre en circulation de l'eau de lavage et/ou de rinçage depuis le réservoir d'eau 6 vers la cuve de lavage 3 de la machine à laver le linge 1, et inversement.Advantageously, at least one water circulation pump 11, 12 of the hydraulic water distribution circuit makes it possible to circulate washing and / or rinsing water from the water tank 6 to the washing tub. 3 of the washing machine 1, and vice versa.

Le circuit hydraulique de distribution d'eau comprend une pluralité de conduites de d'écoulement d'eau 7, 8, 9, 10.The hydraulic water distribution circuit comprises a plurality of water flow lines 7, 8, 9, 10.

Dans un mode de réalisation, le circuit hydraulique de distribution d'eau comprend :

  • ∘ une première pompe de circulation d'eau 11 reliant la cuve de lavage 3 à au moins une vanne 14, et
  • ∘ une deuxième pompe de circulation d'eau 12 reliant le réservoir d'eau de lavage et/ou de rinçage 6 à ladite au moins une vanne 14.
In one embodiment, the hydraulic water distribution circuit comprises:
  • A first water circulation pump 11 connecting the washing tub 3 to at least one valve 14, and
  • A second water circulation pump 12 connecting the washing and / or rinsing water reservoir 6 to the at least one valve 14.

Ici, la première pompe de circulation d'eau 11 montée en sortie de la cuve de lavage 3 de la machine à laver le linge 1 permet d'une part d'alimenter en eau de lavage et/ou de rinçage le réservoir d'eau 6 depuis la cuve de lavage 3 de la machine à laver le linge 1 et d'autre part de vidanger la cuve de lavage 3 vers le réseau d'eau usée externe 13. Et la deuxième pompe de circulation d'eau 12 montée sur le réservoir d'eau 6 permet d'une part d'alimenter en eau de lavage et/ou de rinçage la cuve de lavage 3 de la machine à laver le linge 1 depuis le réservoir d'eau 6 et d'autre part de vidanger le réservoir d'eau 6 vers le réseau d'eau usée externe 13.Here, the first water circulation pump 11 mounted at the outlet of the washing tub 3 of the washing machine 1 makes it possible on the one hand to supply wash water and / or rinse the water tank. 6 from the washing tub 3 of the washing machine 1 and secondly to empty the washing tub 3 to the external waste water network 13. And the second water circulation pump 12 mounted on the water tank 6 allows on the one hand to supply washing water and / or rinse the washing tub 3 of the washing machine 1 from the water tank 6 and on the other hand to drain the water tank 6 to the external waste water network 13.

Une desdites première et deuxième pompes de circulation d'eau 11, 12 est adaptée à permettre le passage d'un flux d'eau depuis la cuve de lavage 3 jusqu'au réservoir d'eau 6, et inversement, lorsque celle-ci est inactive pendant qu'une autre desdites première et deuxième pompes de circulation d'eau 11, 12 est active.One of said first and second water circulation pumps 11, 12 is adapted to allow the passage of a stream of water from the washing tub 3 to the water tank 6, and vice versa, when this is inactive while another one of said first and second water circulation pumps 11, 12 is active.

Ainsi, une desdites première et deuxième pompes de circulation d'eau 11, 12 étant à l'arrêt est adaptée à laisser passer un flux d'eau au travers de celle-ci lorsque l'autre desdites première et deuxième pompes de circulation d'eau 11, 12 fonctionne de sorte à ne pas bloquer la circulation d'eau au travers du circuit hydraulique de distribution d'eau de la machine à laver le linge 1, et inversement.Thus, one of said first and second water circulation pumps 11, 12 being stopped is adapted to allow a flow of water to flow therethrough when the other of said first and second circulation pumps of water 11, 12 operates so as not to block the flow of water through the hydraulic water distribution circuit of the washing machine 1, and vice versa.

De cette manière, le circuit hydraulique de distribution d'eau entre la cuve de lavage 3 et le réservoir d'eau 6 comportant deux pompes de circulation d'eau 11, 12 et au moins une vanne 14 est simplifié de sorte à limiter les coûts d'obtention et à garantir la fiabilité de la machine à laver le linge 1.In this way, the hydraulic water distribution circuit between the washing tank 3 and the water tank 6 comprising two water circulation pumps 11, 12 and at least one valve 14 is simplified so as to limit the costs. obtaining and guaranteeing reliability of the washing machine 1.

Avantageusement, lesdites première et deuxième pompes de circulation d'eau 11, 12 sont des pompes centrifuges.Advantageously, said first and second water circulation pumps 11, 12 are centrifugal pumps.

La spécificité de ces pompes centrifuges consiste en ce qu'elles permettent le passage d'un flux d'eau à l'intérieur de leur corps lorsqu'elles ne sont pas mises en fonctionnement.The specificity of these centrifugal pumps is that they allow the passage of a flow of water inside their body when they are not put into operation.

Ici, la deuxième pompe de circulation d'eau 12 est située en un point bas du réservoir d'eau 6.Here, the second water circulation pump 12 is located at a low point of the water tank 6.

Ainsi, la deuxième pompe de circulation d'eau 12 permet de vider le réservoir d'eau 6.Thus, the second water circulation pump 12 makes it possible to empty the water tank 6.

Le positionnement de la deuxième pompe de circulation d'eau 12 étant une pompe centrifuge est également lié à sa conception puisque cette pompe de circulation d'eau ne peut fonctionner qu'en étant gavée d'eau et non en aspirant de l'eau.The positioning of the second water circulation pump 12 being a centrifugal pump is also related to its design since this water circulation pump can only work when it is filled with water and not by sucking in water.

Par ailleurs, le positionnement de la deuxième pompe de circulation d'eau 12 en un point bas du réservoir d'eau 6 est également lié à l'espace disponible à l'intérieur de la carrosserie 2 de la machine à laver le linge 1 de sorte à optimiser les dimensions de la cuve de lavage 3 de la machine à laver le linge 1 et du réservoir d'eau 6.Furthermore, the positioning of the second water circulation pump 12 at a low point of the water tank 6 is also related to the space available inside the body 2 of the washing machine 1 of the so as to optimize the dimensions of the washing tub 3 of the washing machine 1 and the water tank 6.

Le réservoir d'eau 6 comprend au moins une connexion pour une conduite de circulation d'eau 7, et une connexion pour une conduite de vidange 8.The water tank 6 comprises at least one connection for a water circulation line 7, and a connection for a drain line 8.

Le réservoir d'eau 6 est alimenté en eau de lavage et/ou de rinçage par une conduite de circulation d'eau 7 provenant de la cuve de lavage 3 de la machine à laver le linge 1. L'alimentation en eau de lavage et/ou de rinçage du réservoir d'eau 6 depuis la cuve de lavage 3 de la machine à laver le linge 1 peut être mise en oeuvre par la première pompe de circulation d'eau 11 de la machine à laver le linge 1, en particulier une pompe de vidange.The water tank 6 is supplied with washing water and / or rinsing water via a water circulation pipe 7 coming from the washing tub 3 of the washing machine 1. The washing water supply and or rinsing the water tank 6 from the washing tub 3 of the washing machine 1 can be implemented by the first water circulation pump 11 of the washing machine 1, in particular a drain pump.

La matière plastique du réservoir d'eau 6 est définie de sorte à minimiser le coût d'obtention de celui-ci, à garantir la stabilité dimensionnelle du réservoir d'eau 6, la compatibilité avec l'eau de lavage et/ou de rinçage introduite dans le réservoir d'eau 6, et ici à garantir l'aspect esthétique d'une face visible du réservoir d'eau 6 à l'extérieur de la machine à laver 1.The plastic material of the water tank 6 is defined so as to minimize the cost of obtaining it, to guarantee the dimensional stability of the water tank 6, the compatibility with the washing and / or rinsing water introduced into the water tank 6, and here to ensure the aesthetic appearance of a visible face of the water tank 6 outside the washing machine 1.

La matière plastique peut également être chargée, en particulier avec un agent antibactérien.The plastic material can also be loaded, particularly with an antibacterial agent.

On va décrire à présent, en référence aux figures 3 à 9, un réservoir d'eau de lavage et/ou de rinçage d'une machine à laver selon un mode de réalisation de l'invention.We will now describe, with reference to Figures 3 to 9 , a wash water tank and / or rinse a washing machine according to one embodiment of the invention.

Le réservoir d'eau de lavage et/ou de rinçage 6 d'une machine à laver 1 comprend deux parois 6a, 6b en forme de coque. Une première paroi 6a est disposée en vis-à-vis d'une deuxième paroi 6b. Les deux parois 6a, 6b sont assemblées ensemble.The washing and / or rinsing water tank 6 of a washing machine 1 comprises two shell-like walls 6a, 6b. A first wall 6a is disposed vis-à-vis a second wall 6b. The two walls 6a, 6b are assembled together.

Dans le mode de réalisation illustré aux figures 3 à 9, le réservoir d'eau 6 comprend une première paroi 6a en forme de coque et une deuxième paroi 6b en forme de coque.In the embodiment illustrated in Figures 3 to 9 , the water tank 6 comprises a first shell-shaped wall 6a and a second shell-shaped wall 6b.

La première paroi 6a en forme coque peut constituer une partie d'une paroi de la carrosserie 2 de la machine à laver 1, en particulier de la paroi avant 2a de la carrosserie 2.The first shell-shaped wall 6a may constitute part of a wall of the bodywork 2 of the washing machine 1, in particular of the front wall 2a of the bodywork 2.

La deuxième paroi 6b en forme de coque est disposée à l'intérieur de la carrosserie 2 de la machine à laver 1 et comporte les organes de fonctionnement du réservoir d'eau 6, tels que la vanne 14 et la pompe de circulation d'eau 12.The second shell-shaped wall 6b is disposed inside the body 2 of the washing machine 1 and comprises the operating members of the water tank 6, such as the valve 14 and the water circulation pump. 12.

La zone de stockage d'eau de lavage et/ou de rinçage 6c du réservoir d'eau 6 est formée par l'assemblage des deux parois 6a, 6b en forme de coque du réservoir d'eau 6.The washing water and / or rinsing water storage area 6c of the water tank 6 is formed by assembling the two shell-like walls 6a, 6b of the water tank 6.

La première conduite de circulation d'eau 10, la conduite de trop plein 9 et la deuxième partie 7b de la deuxième conduite de circulation d'eau 7 sont ménagées à l'intérieur du réservoir d'eau 6 et formées par l'assemblage des deux parois 6a, 6b en forme de coque du réservoir d'eau 6.The first water circulation pipe 10, the overflow pipe 9 and the second part 7b of the second water circulation pipe 7 are formed inside the water tank 6 and formed by the assembly of the water pipes. two shell-shaped walls 6a, 6b of the water tank 6.

La fixation des deux parois 6a, 6b en forme de coque du réservoir d'eau 6 peut être réalisée par soudure, en particulier par un procédé de soudure en miroir au moyen de lames chauffante.Fixing the two shell-like walls 6a, 6b of the water tank 6 can be made by welding, in particular by a method of mirror-welding by means of heating blades.

Bien entendu, le mode de fixation des deux parois en forme de coque du réservoir d'eau n'est nullement limitatif et peut être différent, en particulier par vissage.Of course, the method of fixing the two shell-shaped walls of the water tank is in no way limiting and may be different, in particular by screwing.

Le réservoir d'eau de lavage et/ou de rinçage 6 comprend également des moyens de renforcement 7b, 9, 10, 21, 22 ménagés dans au moins l'une des deux parois 6a, 6b du réservoir d'eau 6 et s'étendant entre les deux parois 6a, 6b du réservoir d'eau 6 de sorte à maintenir l'écartement entre les deux parois 6a, 6b.The washing and / or rinsing water tank 6 also comprises reinforcing means 7b, 9, 10, 21, 22 formed in at least one of the two walls 6a, 6b of the water tank 6 and extending between the two walls 6a, 6b of the water tank 6 so as to maintain the spacing between the two walls 6a, 6b.

Ainsi, lorsque des efforts sont appliqués sur une des deux parois 6a, 6b du réservoir d'eau 6, l'écartement entre les deux parois 6a, 6b du réservoir d'eau 6 est maintenu grâce aux moyens de renforcement 7b, 9, 10, 21, 22.Thus, when forces are applied to one of the two walls 6a, 6b of the water tank 6, the spacing between the two walls 6a, 6b of the water tank 6 is maintained by means of the reinforcing means 7b, 9, 10 , 21, 22.

Avantageusement, la deuxième paroi 6b du réservoir d'eau 6 comprend au moins une partie des moyens de renforcement 22 de sorte à mettre en appui la première paroi 6a du réservoir d'eau 6 contre ladite au moins une partie des moyens de renforcement 22 ménagés dans la deuxième paroi 6b du réservoir d'eau 6.Advantageously, the second wall 6b of the water tank 6 comprises at least a part of the reinforcement means 22 so as to bear the first wall 6a of the water tank 6 against said at least part of the reinforcement means 22 formed in the second wall 6b of the water tank 6.

Ainsi, lorsque le réservoir d'eau 6 forme au moins en partie une paroi de la carrosserie 2, par exemple la paroi avant 2a, de la machine à laver 1, l'écartement entre les deux parois 6a, 6b en forme de coque constituant le réservoir d'eau 6 est maintenu lorsque des objets ou des personnes viennent en appui contre la paroi 6a du réservoir d'eau 6 et exercent une pression sur ladite paroi 6a.Thus, when the water reservoir 6 forms at least in part a wall of the 2, for example the front wall 2a, the washing machine 1, the spacing between the two walls 6a, 6b in the form of shell constituting the water reservoir 6 is maintained when objects or people come to bear against the wall 6a of the water tank 6 and exert a pressure on said wall 6a.

En pratique, lors d'un appui sur la première paroi 6a du réservoir d'eau 6, la déformation de la première paroi 6a du réservoir d'eau 6 est limitée, et en particulier à un espace e entre ladite au moins une partie des moyens de renforcement 22 et la première paroi 6a du réservoir d'eau 6, tel qu'illustré à la figure 6.In practice, when pressing on the first wall 6a of the water tank 6, the deformation of the first wall 6a of the water reservoir 6 is limited, and in particular to a space e between said at least a portion of the reinforcement means 22 and the first wall 6a of the water tank 6, as illustrated in FIG. figure 6 .

L'espace e ménagé entre ladite au moins une partie des moyens de renforcement 22 et la première paroi 6a du réservoir d'eau 6 est un jeu fonctionnel pour la fixation des première et deuxième parois 6a, 6b du réservoir d'eau 6.The space e provided between said at least part of the reinforcing means 22 and the first wall 6a of the water tank 6 is a functional clearance for fixing the first and second walls 6a, 6b of the water tank 6.

A titre d'exemple non limitatif, l'espace e ménagé entre ladite au moins une partie des moyens de renforcement 22 et la première paroi 6a du réservoir d'eau 6 est de l'ordre de 1 mm, et l'épaisseur du réservoir d'eau entre les deux parois 6a, 6b vaut environ 28mm à 45mm au niveau des moyens de renforcement 22.By way of nonlimiting example, the space e provided between said at least part of the reinforcement means 22 and the first wall 6a of the water tank 6 is of the order of 1 mm, and the thickness of the reservoir water between the two walls 6a, 6b is about 28mm to 45mm at the reinforcement means 22.

Avantageusement, le réservoir d'eau 6 comprend une première série de moyens de renforcement 7b, 9, 10, 21 ménagés dans la première paroi 6a du réservoir d'eau 6 et une deuxième série de moyens de renforcement 7b, 9, 10, 21 ménagés dans la deuxième paroi 6b du réservoir d'eau 6, où la première série de moyens de renforcement 7b, 9, 10, 21 est en appui contre la deuxième série de moyens de renforcement 7b, 9, 10, 21.Advantageously, the water tank 6 comprises a first series of reinforcing means 7b, 9, 10, 21 formed in the first wall 6a of the water tank 6 and a second series of reinforcement means 7b, 9, 10, 21 formed in the second wall 6b of the water tank 6, where the first series of reinforcing means 7b, 9, 10, 21 bears against the second series of reinforcement means 7b, 9, 10, 21.

Ainsi, lorsque des efforts sont exercés sur les parois 6a, 6b du réservoir d'eau 6, l'écartement entre les deux parois 6a, 6b du réservoir d'eau 6 est maintenu grâce aux première et deuxième séries de moyens de renforcement 7b, 9, 10, 21.Thus, when forces are exerted on the walls 6a, 6b of the water tank 6, the spacing between the two walls 6a, 6b of the water tank 6 is maintained by means of the first and second series of reinforcement means 7b, 9, 10, 21.

En pratique, les moyens de renforcement 7b, 9, 10, 21 de la première série de moyens de renforcement ménagés dans la première paroi 6a du réservoir d'eau 6 et les moyens de renforcement 7b, 9, 10, 21 de la deuxième série de moyens de renforcement ménagés dans la deuxième paroi 6b du réservoir d'eau 6 sont disposés en vis-à-vis sur les première et deuxième parois 6a, 6b du réservoir d'eau 6.In practice, the reinforcing means 7b, 9, 10, 21 of the first series of reinforcement means formed in the first wall 6a of the water tank 6 and the reinforcement means 7b, 9, 10, 21 of the second series reinforcement means provided in the second wall 6b of the water tank 6 are arranged facing the first and second walls 6a, 6b of the water tank 6.

Préférentiellement, les moyens de renforcement 7b, 9, 10, 21 des première et deuxième séries de moyens de renforcement sont fixés ensemble.Preferably, the reinforcing means 7b, 9, 10, 21 of the first and second series of reinforcing means are fixed together.

Ainsi, le maintien de l'écartement entre les deux parois 6a, 6b est garanti par la fixation des moyens de renforcement 7b, 9, 10, 21.Thus, maintaining the spacing between the two walls 6a, 6b is guaranteed by fixing the reinforcing means 7b, 9, 10, 21.

Ainsi, l'eau de lavage et/ou de rinçage stockée dans le réservoir d'eau 6 ne risque pas de déformer le réservoir d'eau 6 en le faisant gonfler du fait de la pression exercée par l'eau de lavage et/ou de rinçage sur les parois 6a, 6b du réservoir d'eau 6 car les moyens de renforcement 7b, 9, 10, 21 disposés en vis-à-vis sur les deux parois 6a, 6b du réservoir d'eau 6 sont fixés ensemble.Thus, the washing and / or rinsing water stored in the water tank 6 is not likely to deform the water tank 6 by causing it to swell due to the pressure exerted by the washing water and / or rinsing the walls 6a, 6b of the water tank 6 because the reinforcing means 7b, 9, 10, 21 arranged vis-a-vis the two walls 6a, 6b of the water tank 6 are fixed together.

Les moyens de renforcement 7b, 9, 10, 21 empêchent également la déformation des parois 6a, 6b du réservoir d'eau 6 vers l'intérieur de celui-ci lorsque des efforts sont appliqués aux parois 6a, 6b du réservoir d'eau 6 depuis l'extérieur et en direction de l'intérieur du réservoir d'eau 6.The reinforcing means 7b, 9, 10, 21 also prevent the deformation of the walls 6a, 6b of the water tank 6 towards the inside thereof when forces are applied to the walls 6a, 6b of the water tank 6 from outside and towards the inside of the water tank 6.

Avantageusement, les moyens de renforcement 7b, 9, 10, 21 des première et deuxième séries de moyens de renforcement sont fixés ensemble par soudure.Advantageously, the reinforcing means 7b, 9, 10, 21 of the first and second series of reinforcing means are fastened together by welding.

Ainsi, aucune pièce supplémentaire n'est nécessaire pour maintenir l'écartement des deux parois 6a, 6b du réservoir d'eau 6.Thus, no additional room is necessary to maintain the spacing of the two walls 6a, 6b of the water tank 6.

Grâce aux moyens de renforcement 7b, 9, 10, 21, la construction du réservoir d'eau 6 est simplifiée et peu onéreuse.Thanks to the reinforcing means 7b, 9, 10, 21, the construction of the water tank 6 is simplified and inexpensive.

Avantageusement, au moins une partie des moyens de renforcement 7b, 9, 10 est formée par des cloisons des première et deuxième parties d'au moins une conduite d'écoulement d'eau 7b, 9, 10 ménagées respectivement dans les première et deuxième parois 6a, 6b du réservoir d'eau 6.Advantageously, at least a portion of the reinforcing means 7b, 9, 10 is formed by partitions of the first and second parts of at least one water flow line 7b, 9, 10 formed respectively in the first and second walls. 6a, 6b of the water tank 6.

Ainsi, les conduites d'écoulement d'eau 7b, 9, 10 internes au réservoir d'eau 6 permettent d'une part la circulation du liquide de lavage et/ou de rinçage à l'intérieur du réservoir d'eau 6 sans ajout de pièce supplémentaire, et d'autre part leurs cloisons assurent également le renforcement du réservoir d'eau 6 dans différentes zones du réservoir d'eau 6, et ce sans coût additionnel. Par exemple, la conduite de trop-plein 9, bien visible sur la figure 5, assure la rigidité du réservoir d'eau 6 suivant la hauteur de celui-ci et dans sa partie centrale.Thus, the water flow lines 7b, 9, 10 internal to the water tank 6 allow on the one hand the circulation of the washing and / or rinsing liquid inside the water tank 6 without adding additional room, and secondly their partitions also provide the strengthening of the water reservoir 6 in different areas of the water tank 6, and this without additional cost. For example, the overflow pipe 9, clearly visible on the figure 5 , ensures the rigidity of the water tank 6 according to the height thereof and in its central part.

En pratique, les moyens de renforcement 7b, 9, 10 sont constitués d'une première série de moyens de renforcement ménagés dans la première paroi 6a du réservoir d'eau 6 et d'une deuxième série de moyens de renforcement ménagés dans la deuxième paroi 6b du réservoir d'eau 6. Ces deux séries de moyens de renforcement sont disposées en vis-à-vis sur les première et deuxième parois 6a, 6b du réservoir d'eau 6 et sont fixées ensemble pour constituer à la fois des moyens de renforcement 7b, 9, 10 et des conduites d'écoulement d'eau 7b, 9, 10 internes au réservoir d'eau 6.In practice, the reinforcing means 7b, 9, 10 consist of a first series of reinforcing means formed in the first wall 6a of the water tank 6 and a second series of reinforcement means formed in the second wall 6b of the water tank 6. These two series of reinforcing means are arranged vis-à-vis the first and second walls 6a, 6b of the water tank 6 and are fixed together to constitute both means of reinforcement 7b, 9, 10 and water flow lines 7b, 9, 10 internal to the water tank 6.

Préférentiellement, une partie des moyens de renforcement 21, 22 sont des plots.Preferably, a portion of the reinforcing means 21, 22 are studs.

Il est ainsi possible de répartir des plots 21, 22 agissant comme moyens de renforcement en différents points à l'intérieur du réservoir d'eau 6 de sorte que le réservoir d'eau 6 soit renforcé de manière globale et homogène.It is thus possible to distribute pads 21, 22 acting as reinforcement means at different points inside the water tank 6 so that the water tank 6 is reinforced in a global and homogeneous manner.

Ici, les plots 22 empêchent les déformations des parois 6a, 6b du réservoir d'eau 6 vers l'intérieur de celui-ci. Par exemple, lorsque des efforts sont appliqués à la paroi 6a du réservoir d'eau 6 depuis l'extérieur et en direction de l'intérieur du réservoir d'eau 6, la paroi 6a est mise en appui contre les plots 22 qui supportent les efforts appliqués à la paroi 6a. Ainsi la paroi 6a ne se déforme pas.Here, the pads 22 prevent deformation of the walls 6a, 6b of the water tank 6 towards the inside thereof. For example, when forces are applied to the wall 6a of the water tank 6 from the outside and towards the inside of the water tank 6, the wall 6a is put in abutment against the studs 22 which support the applied forces to the wall 6a. Thus the wall 6a does not deform.

Les plots 21 sont constitués de deux séries de plots ménagés en vis-à-vis sur les première et deuxième parois 6a, 6b du réservoir d'eau 6 et fixés ensemble. Ainsi, les plots 21 empêchent les déformations des parois 6a, 6b du réservoir d'eau 6 vers l'intérieur lorsque des efforts sont appliqués aux parois 6a, 6b du réservoir d'eau 6 depuis l'extérieur et en direction de l'intérieur de celui-ci. Les plots 21 empêchent également les déformations des parois 6a, 6b du réservoir d'eau 6 vers l'extérieur du réservoir d'eau 6, lorsque des efforts sont exercés en direction de l'extérieur du réservoir d'eau 6, par exemple par le liquide contenu dans le réservoir d'eau 6.The pads 21 consist of two series of pads arranged vis-à-vis the first and second walls 6a, 6b of the water tank 6 and fixed together. Thus, the pads 21 prevent deformation of the walls 6a, 6b of the water tank 6 inwardly when forces are applied to the walls 6a, 6b of the water tank 6 from the outside and towards the inside. of it. The pads 21 also prevent deformation of the walls 6a, 6b of the water tank 6 towards the outside of the water tank 6, when forces are exerted towards the outside of the water tank 6, for example by the liquid contained in the water tank 6.
