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.

Cependant, ces machines à laver présentent l'inconvénient que les conduites de circulation d'eau souples reliant la cuve de lavage au réservoir d'eau sont disposées à l'extérieur du réservoir d'eau et connectées à des embouts de connexion du réservoir d'eau.However, these washing machines have the disadvantage that the flexible water circulation lines connecting the wash tub to the water tank are arranged outside the water tank and connected to the connection ends of the water tank. 'water.

Par conséquent, ces conduites de circulation d'eau souples augmentent le coût d'obtention de la machine à laver pourvue d'un réservoir d'eau.Therefore, these flexible water circulation lines increase the cost of obtaining the washing machine provided with a water tank.

On connaît également le document EP 0 911 439 A1 qui décrit un réservoir d'eau de lavage et/ou de rinçage d'une machine à laver comprenant au moins une conduite de circulation d'eau, où ladite au moins une conduite de circulation d'eau est ménagée à l'intérieur du réservoir d'eau.The document is also known EP 0 911 439 A1 which describes a wash water tank and / or rinse a washing machine comprising at least one water circulation pipe, wherein said at least one water circulation pipe is formed inside the tank of water.

Lors de l'intégration d'au moins une conduite de circulation d'eau à l'intérieur du réservoir d'eau, deux parois opposées du réservoir d'eau sont reliées entre elles par des cloisons internes au réservoir d'eau.When integrating at least one water circulation pipe inside the water tank, two opposite walls of the water tank are interconnected by partitions internal to the water tank.

Cependant, une telle disposition de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau présente l'inconvénient que ladite au moins une conduite de circulation d'eau est de profondeur égale à l'épaisseur du réservoir d'eau.However, such an arrangement of said at least one water circulation pipe arranged inside the water tank has the disadvantage that said at least one water circulation pipe is of depth equal to the thickness of the water. water reservoir.

Ainsi, plus l'épaisseur du réservoir d'eau est importante, plus la profondeur de ladite au moins une conduite de circulation d'eau est importante et plus la largeur de ladite au moins une conduite de circulation d'eau est réduite pour maintenir une section d'écoulement d'eau constante au travers de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau.Thus, the greater the thickness of the water reservoir, the greater the depth of said at least one water circulation pipe is and the greater the width of said at least one water circulation pipe is reduced to maintain a constant water flow section through said at least one water circulation pipe arranged inside the water tank.

Par conséquent, la profondeur de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau est limitée.Therefore, the depth of said at least one water circulation pipe formed inside the water tank is limited.

Dans une telle configuration, lorsque le réservoir d'eau comprend au moins une paroi ayant une forme non plane, la section d'écoulement d'eau de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau ne peut être maintenue constante suivant toute la longueur de ladite au moins une conduite de circulation d'eau pour une largeur fixe de ladite au moins une conduite de circulation d'eau puisque ladite au moins une conduite de circulation d'eau est dépendante de l'épaisseur du réservoir d'eau.In such a configuration, when the water reservoir comprises at least one wall having a non-planar shape, the water flow section of the at least one water circulation pipe formed inside the reservoir of water can not be kept constant along the entire length of said at least one water circulation pipe for a fixed width of said at least one water circulation pipe since said at least one water circulation pipe is dependent on the thickness of the water tank.

En outre, l'épaisseur des cloisons internes du réservoir d'eau est dépendante de l'épaisseur du réservoir d'eau. Et en particulier, lorsque le réservoir d'eau est réalisé en matière plastique, l'épaisseur des cloisons internes du réservoir d'eau est déterminée en fonction de l'angle de dépouille permettant le démoulage des pièces constituant le réservoir d'eau.In addition, the thickness of the internal partitions of the water tank is dependent on the thickness of the water tank. And in particular, when the water tank is made of plastic, the thickness of the internal partitions of the water tank is determined according to the draft angle for demolding parts constituting the water tank.

Ainsi, plus l'épaisseur du réservoir d'eau est importante, plus la base des cloisons internes du réservoir d'eau reliée à la face interne des parois du réservoir d'eau est importante.Thus, the greater the thickness of the water tank, the greater the base of the internal walls of the water tank connected to the inner face of the walls of the water tank is important.

Et l'épaisseur des cloisons internes du réservoir d'eau est dépendante de l'épaisseur des parois du réservoir d'eau de sorte à éviter des retassures sur la face externe des parois du réservoir d'eau.And the thickness of the internal partitions of the water tank is dependent on the thickness of the walls of the water tank so as to avoid sink holes on the outer face of the walls of the water tank.

Ainsi, plus l'épaisseur du réservoir d'eau est importante, plus la base des cloisons internes du réservoir d'eau reliée à la face interne des parois du réservoir d'eau est importante, et plus l'épaisseur des parois du réservoir d'eau est importante.Thus, the greater the thickness of the water tank, the greater the base of the internal partitions of the water tank connected to the inner face of the walls of the water tank, and the greater the thickness of the walls of the water tank. water is important.

Par conséquent, le coût d'obtention du réservoir d'eau augmente plus la contenance en eau du réservoir d'eau est importante. Mais la contenance en eau du réservoir d'eau est diminuée par l'épaisseur des cloisons internes et l'épaisseur des parois du réservoir d'eau.Therefore, the cost of obtaining the water tank increases the water capacity of the water tank is important. But the water capacity of the water tank is reduced by the thickness of the internal partitions and the thickness of the walls of the water tank.

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 d'intégrer au moins une conduite de circulation d'eau à l'intérieur dudit réservoir d'eau tout en minimisant le coût d'obtention du réservoir d'eau et en optimisant la contenance en eau du réservoir d'eau.The present invention aims to solve the aforementioned drawbacks and to provide a wash water tank and / or rinse, and a washing machine, for integrating at least one water circulation pipe to the water. interior of said water tank while minimizing the cost of obtaining the water tank and optimizing the water capacity of the water tank.

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 comprenant au moins une conduite de circulation d'eau, ladite au moins une conduite de circulation d'eau étant ménagée à l'intérieur dudit réservoir d'eau.In this regard, the present invention aims, in a first aspect, a washing water tank and / or rinse for a washing machine comprising at least one water circulation pipe, said at least one water circulation pipe. water being formed inside said water tank.

Selon l'invention,

  • ledit réservoir d'eau comprend une première paroi en forme de coque et une deuxième paroi en forme de coque, les première et deuxième parois en forme de coque comprenant des cloisons formant respectivement une première et une deuxième parties de ladite au moins une conduite de circulation d'eau,
  • où lesdites cloisons des première et deuxième parties de ladite au moins une conduite de circulation d'eau ménagées dans les première et deuxième parois en forme de coque coopèrent ensemble de sorte à former ladite au moins une conduite de circulation d'eau, et
  • où des nervures s'étendent entre la face interne de ladite première paroi en forme de coque et au moins l'une des cloisons de ladite première partie de ladite au moins une conduite de circulation d'eau ménagée dans ladite première paroi en forme de coque.
According to the invention,
  • said water tank comprises a first shell-shaped wall and a second shell-shaped wall, the first and second shell-shaped walls including partitions respectively forming first and second portions of said at least one circulation line; of water,
  • wherein said partitions of the first and second portions of said at least one water circulation conduit formed in the first and second shell-shaped walls cooperate together to form said at least one water circulation pipe, and
  • wherein ribs extend between the inner face of said first shell-shaped wall and at least one of the partitions of said first portion of said at least one water-flow conduit formed in said first shell-shaped wall .

Ainsi, les dimensions de profondeur et de largeur de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau sont indépendantes de l'épaisseur du réservoir d'eau.Thus, the depth and width dimensions of the at least one water circulation pipe formed inside the water tank are independent of the thickness of the water tank.

De cette manière, les nervures s'étendant entre la face interne de la première paroi en forme de coque et au moins l'une des cloisons de la première partie de ladite au moins une conduite de circulation d'eau ménagée dans la première paroi en forme de coque permettent de déterminer la profondeur et la largeur de ladite au moins une conduite de circulation d'eau de manière indépendante par rapport à l'épaisseur du réservoir d'eau.In this way, the ribs extending between the inner face of the first shell-shaped wall and at least one of the partitions of the first part of said at least one water circulation duct formed in the first wall hull shape to determine the depth and width of said at least one water circulation pipe independently of the thickness of the water tank.

En outre, l'épaisseur des cloisons des première et deuxième parties de ladite au moins une conduite de circulation d'eau ménagées dans les première et deuxième parois en forme de coque du réservoir d'eau est minimisée puisque des évidements créés par les nervures entre la face interne de la première paroi en forme de coque et la première partie de ladite au moins une conduite de circulation d'eau ménagée dans la première paroi en forme de coque permettent de diminuer la profondeur de la première partie de ladite au moins une conduite de circulation d'eau ménagée dans la première paroi en forme de coque.In addition, the thickness of the partitions of the first and second parts of the at least one water circulation duct formed in the first and second shell-shaped walls of the water tank is minimized since the recesses created by the ribs between the inner face of the first shell-shaped wall and the first part of the at least one water-circulation duct formed in the first shell-shaped wall allow the depth of the first part of the at least one duct to be reduced; water circulation arranged in the first shell-shaped wall.

Et l'épaisseur des première et deuxième parois en forme de coque du réservoir d'eau est également minimisée.And the thickness of the first and second shell-shaped walls of the water tank is also minimized.

De cette manière, le coût d'obtention du réservoir d'eau est minimisé et la contenance en eau du réservoir d'eau est optimisée.In this way, the cost of obtaining the water tank is minimized and the water capacity of the water tank is optimized.

Par ailleurs, les nervures s'étendant entre la face interne de la première paroi en forme de coque et au moins l'une des cloisons de la première partie de ladite au moins une conduite de circulation d'eau ménagée dans la première paroi en forme de coque permettent de rigidifier le réservoir d'eau et ladite au moins une conduite de circulation d'eau.On the other hand, the ribs extending between the inner face of the first shell-shaped wall and at least one of the partitions of the first part of the at least one water-circulation duct formed in the first shaped wall hull allow to stiffen the water tank and said at least one water circulation pipe.

Pratiquement, lesdites nervures de ladite première paroi en forme de coque sont reliées à une cloison de fond de ladite première partie de ladite au moins une conduite de circulation d'eau ménagée dans ladite première paroi en forme de coque.Practically, said ribs of said first shell-shaped wall are connected to a bottom wall of said first portion of said at least one water circulation duct formed in said first shell-shaped wall.

Préférentiellement, le réservoir d'eau de lavage et/ou de rinçage 6 est interne à la carrosserie 2 de la machine à laver 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 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 2nd side wall.

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 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 1 au réservoir d'eau 6.The washing machine 1 comprises a hydraulic water distribution circuit, in which the hydraulic water distribution circuit connects the washing tub 3 of the washing machine 1 to the water tank 6.

La machine à laver 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 mains water supply (not shown) so as to fill the washing tub 3 during the different phases of a washing cycle with water that has not been used during the washing. a previous phase of the current operating cycle or during a previous operating cycle.

Le circuit hydraulique de distribution d'eau de la machine à laver 1 peut être alimenté en eau du réseau par une conduite d'arrivée d'eau du réseau (non représentée) reliée directement à la machine à laver 1 depuis un réseau d'eau externe au moyen d'une électrovanne permettant de réguler la quantité d'eau nécessaire au fonctionnement de la machine à laver 1.The hydraulic water distribution circuit of the washing machine 1 can be fed with water from the network via a mains water inlet pipe (not shown) connected directly to the washing machine 1 from a water network. external by means of a solenoid valve for regulating the quantity of water necessary for the operation of the washing machine 1.

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 1.The hydraulic water distribution circuit comprises at least one water circulation pump 11 so as to fill the water tank 6 with washing and / or rinsing water from the washing tub 3 of the washing machine 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 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 :

  • o une première pompe de circulation d'eau 11 reliant la cuve de lavage 3 à au moins une vanne 14, et
  • o 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 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 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 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 drain 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 wastewater 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 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 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 the 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 1 de sorte à optimiser les dimensions de la cuve de lavage 3 de la machine à laver 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 so that 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 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 1 peut être mise en oeuvre par la première pompe de circulation d'eau 11 de la machine à laver 1, en particulier une pompe de vidange.The water tank 6 is supplied with wash 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.

Le réservoir d'eau 6 alimente en eau de lavage et/ou de rinçage, d'une phase précédente d'un cycle de fonctionnement en cours de mise en oeuvre ou d'un cycle de fonctionnement précédent, la cuve de lavage 3 de la machine à laver 1 par une conduite de circulation d'eau 7. L'alimentation en eau de lavage et/ou de rinçage de la cuve de lavage 3 de la machine à laver 1 depuis le réservoir d'eau 6 peut être mise en oeuvre par la deuxième pompe de circulation d'eau 12 du réservoir d'eau 6, en particulier une pompe de vidange.The water tank 6 supplies washing water and / or rinsing water, a previous phase of an operating cycle during implementation or a previous operating cycle, the washing tank 3 of the washing machine 1 by a water circulation pipe 7.

Ici, la matière plastique employée est destinée à permettre la soudure des première et deuxième parois en forme de coque 6a, 6b du réservoir d'eau 6.Here, the plastic material used is intended to allow the welding of the first and second shell-shaped walls 6a, 6b of the water tank 6.

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.

Ici et de manière nullement limitative, les nervures 18 ménagées entre la face interne de la première paroi en forme de coque 6a et au moins l'une des cloisons 9a, 9c, 10a, 10c de la première partie de ladite au moins une conduite de circulation d'eau 9, 10 ménagée dans la première paroi en forme de coque 6a sont obtenues lors du moulage de la première paroi en forme de coque 6a suivant un processus de moulage par des jeux de cales montantes.Here and in no way limiting, the ribs 18 formed between the inner face of the first shell-shaped wall 6a and at least one of the partitions 9a, 9c, 10a, 10c of the first part of said at least one pipe of water circulation 9, 10 formed in the first shell-shaped wall 6a are obtained during the molding of the first shell-shaped wall 6a following a molding process by sets of rising wedges.

Avantageusement, la profondeur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 est inférieure à l'épaisseur du réservoir d'eau 6 constitué par les première et deuxième parois en forme de coque 6a, 6b.Advantageously, the depth of said at least one water circulation pipe 9, 10 formed inside the water tank 6 is less than the thickness of the water tank 6 constituted by the first and second shaped walls. hull 6a, 6b.

Ainsi, les dimensions de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 sont déterminées en fonction de la section d'écoulement d'eau souhaitée.Thus, the dimensions of said at least one water circulation pipe 9, 10 formed inside the water tank 6 are determined according to the desired water flow section.

De cette manière, la profondeur et la largeur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 peuvent être définies au moyen des nervures 18 de la première paroi en forme de coque 6a de sorte que la section d'écoulement d'eau de celle-ci soit équivalente à la section d'écoulement d'eau d'une conduite d'écoulement d'eau connectée au réservoir d'eau 6, en particulier la première partie 7a de la deuxième conduite de circulation d'eau 7 et/ou la conduite de vidange 8.In this way, the depth and the width of said at least one water circulation pipe 9, 10 formed inside the water tank 6 can be defined by means of the ribs 18 of the first shell-shaped wall. 6a so that the water flow section thereof is equivalent to the water flow section of a water flow line connected to the water tank 6, in particular the first part 7a of the second water circulation pipe 7 and / or the drain pipe 8.

Les nervures 18 de la première paroi en forme de coque 6a permettent d'adapter la profondeur et la largeur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 en fonction de la section d'écoulement d'eau souhaitée. La profondeur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 peut ainsi être inférieure à l'épaisseur du réservoir d'eau 6.The ribs 18 of the first shell-shaped wall 6a make it possible to adapt the depth and the width of the at least one water circulation pipe 9, 10 formed inside the water tank 6 as a function of the desired water flow section. The depth of said at least one water circulation pipe 9, 10 formed inside the water tank 6 can thus be less than the thickness of the water tank 6.

A titre d'exemple nullement limitatif, la section d'écoulement d'eau de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 est de l'ordre de 200mm2 ainsi que la première partie 7a de la deuxième conduite de circulation d'eau 7 reliant le réservoir d'eau 6 à la cuve de lavage 3 et que la conduite de vidange 8 reliant le réservoir d'eau 6 au réseau d'eau usée externe 13 de sorte à garantir le fonctionnement de la machine à laver 1 lors de la circulation d'eau au travers du circuit hydraulique de distribution d'eau.By way of non-limiting example, the water flow section of the at least one water circulation pipe 9, 10 formed inside the water tank 6 is of the order of 200 mm 2 and that the first part 7a of the second water circulation pipe 7 connecting the water tank 6 to the washing tank 3 and the drain line 8 connecting the water tank 6 to the external waste water network 13 so as to guarantee the operation of the washing machine 1 during the circulation of water through the hydraulic water distribution circuit.

Ici et de manière nullement limitative, ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 présente une largeur de l'ordre de 12mm et une profondeur de l'ordre de 18mm, soit une section d'écoulement d'eau de l'ordre de 216mm2.Here and in no way limiting, said at least one water circulation pipe 9, 10 formed inside the water tank 6 has a width of the order of 12mm and a depth of about 18mm, either a water flow section of the order of 216 mm 2 .

Pratiquement, les nervures 18 de la première paroi en forme de coque 6a sont reliées à une cloison de fond 9c, 10c de la première partie de ladite au moins une conduite de circulation d'eau 9, 10 ménagée dans la première paroi en forme de coque 6a.In practice, the ribs 18 of the first shell-shaped wall 6a are connected to a bottom wall 9c, 10c of the first part of said at least one water circulation pipe 9, 10 formed in the first shell-shaped wall 6a.

Avantageusement, les nervures 18 s'étendent entre la face interne de la première paroi en forme de coque 6a et la cloison de fond 9c, 10c de la première partie de ladite au moins une conduite de circulation d'eau 9, 10 ménagée dans la première paroi en forme de coque 6a.Advantageously, the ribs 18 extend between the inner face of the first shell-shaped wall 6a and the bottom wall 9c, 10c of the first part of the at least one water circulation pipe 9, 10 formed in the first shell-shaped wall 6a.

Ainsi, les évidements créés par les nervures 18 s'étendant entre la face interne de la première paroi en forme de coque 6a et la cloison de fond 9c, 10c de la première partie de ladite au moins une conduite de circulation d'eau 9, 10 ménagée dans la première paroi en forme de coque 6a permettent d'augmenter la contenance en eau du réservoir d'eau 6 sans augmenter le volume global du réservoir d'eau 6.Thus, the recesses created by the ribs 18 extending between the inner face of the first shell-shaped wall 6a and the bottom wall 9c, 10c of the first part of said at least one water circulation pipe 9, 10 formed in the first shell-shaped wall 6a can increase the water capacity of the water tank 6 without increasing the overall volume of the water tank 6.

Préférentiellement, les nervures 18 de la première paroi en forme de coque 6a présentent une épaisseur à leur base, c'est-à-dire au niveau de la jonction des nervures 18 avec la face interne de la première paroi en forme de coque 6a, comprise entre 30% et 45% de l'épaisseur de la paroi en forme de coque 6a.Preferably, the ribs 18 of the first shell-shaped wall 6a have a thickness at their base, that is to say at the junction of the ribs 18 with the inner face of the first shell-shaped wall 6a, between 30% and 45% of the thickness of the shell-shaped wall 6a.

Ainsi, une telle détermination de l'épaisseur des nervures 18 de la première paroi en forme de coque 6a par rapport à l'épaisseur de la paroi en forme de coque 6a permet de limiter la formation de retassures au niveau de la paroi en forme de coque 6a.Thus, such a determination of the thickness of the ribs 18 of the first shell-shaped wall 6a with respect to the thickness of the shell-shaped wall 6a makes it possible to limit the formation of shrinkage at the wall in the form of a shell. shell 6a.

De cette manière, la paroi en forme de coque 6a du réservoir d'eau 6 peut être utilisée en tant que pièce d'esthétique du réservoir d'eau 6, et en particulier constituer au moins en partie une paroi de la carrosserie 2 de la machine à laver 1, telle que par exemple la paroi avant 2a de la carrosserie 2.In this way, the shell-shaped wall 6a of the water tank 6 can be used as an aesthetic part of the water tank 6, and in particular at least partly constitute a wall of the bodywork 2 of the washing machine 1, such as for example the front wall 2a of the bodywork 2.

Ici et de manière nullement limitative, les nervures 18 de la première paroi en forme de coque 6a présentent une épaisseur à leur base de l'ordre de 1,5mm, c'est-à-dire au niveau de la jonction des nervures 18 avec la face interne de la première paroi en forme de coque 6a, et la première paroi en forme de coque 6a présente une épaisseur de l'ordre de 3,5mm.Here and in no way limiting, the ribs 18 of the first shell-shaped wall 6a have a thickness at their base of the order of 1.5 mm, that is to say at the junction of the ribs 18 with the inner face of the first shell-shaped wall 6a, and the first shell-shaped wall 6a has a thickness of the order of 3.5mm.

Une pluralité des nervures 18 est disposée transversalement au sens d'écoulement d'un flux d'eau à l'intérieur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6.A plurality of the ribs 18 is disposed transversely to the direction of flow of a water flow inside said at least one water circulation pipe 9, 10 formed inside the water tank 6.

Ici, lors du moulage de la première paroi en forme de coque 6a suivant un processus de moulage par des jeux de cales montantes, la disposition de nervures 18 transversalement au sens d'écoulement d'un flux d'eau à l'intérieur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 permet de limiter la course des cales montantes et ainsi d'utiliser plusieurs cales montantes.Here, during the molding of the first shell-shaped wall 6a following a molding process by sets of rising wedges, the provision of ribs 18 transversely to the direction of flow of a stream of water inside said at least one water circulation pipe 9, 10 formed inside the water tank 6 makes it possible to limit the stroke of the upstream shims and thus to use several upward shims.

En outre, la disposition de nervures 18 transversalement au sens d'écoulement d'un flux d'eau à l'intérieur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 et s'étendant suivant la hauteur du réservoir d'eau 6 permet de remplir en eau de lavage et/ou de rinçage les évidements créés par les nervures 18.In addition, the provision of ribs 18 transversely to the direction of flow a flow of water within said at least one water circulation pipe 9, 10 formed inside the water tank 6 and extending along the height of the water tank 6 allows filling the recesses created by the ribs with washing and / or rinsing water.

Dans le cas où une pluralité des nervures 18 serait disposée longitudinalement au sens d'écoulement d'un flux d'eau à l'intérieur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 empêcherait de remplir en eau de lavage et/ou de rinçage les évidements créés par les nervures 18 à cause de la pression de l'air emprisonné à l'intérieur desdits évidements.In the case where a plurality of ribs 18 would be disposed longitudinally in the direction of flow of a stream of water within said at least one water circulation pipe 9, 10 formed inside the reservoir of water. water 6 would prevent filling with wash water and / or rinsing the recesses created by the ribs 18 because of the pressure of the air trapped inside said recesses.

Avantageusement, la première partie de ladite au moins une conduite de circulation d'eau 9 ménagée dans la première paroi en forme de coque 6a comprend une cloison latérale 9a s'étendant au-delà de la cloison de fond 9c et jusqu'à la face interne de la première paroi en forme de coque 6a.Advantageously, the first part of the at least one water circulation pipe 9 formed in the first shell-shaped wall 6a comprises a lateral partition 9a extending beyond the bottom wall 9c and up to the face internal of the first shell-shaped wall 6a.

Ainsi, la cloison latérale 9a de la première paroi en forme de coque 6a permet de rigidifier le réservoir d'eau 6.Thus, the side wall 9a of the first shell-shaped wall 6a makes it possible to stiffen the water tank 6.

En outre, une telle cloison latérale 9a de la première paroi en forme de coque 6a permet de faciliter le remplissage en matière plastique lors du processus de moulage de la première paroi en forme de coque 6a.In addition, such a side wall 9a of the first shell-shaped wall 6a facilitates the filling of plastic material during the molding process of the first shell-shaped wall 6a.

Par ailleurs, la cloison latérale 9a de la première paroi en forme de coque 6a permet de prolonger ladite au moins une conduite de circulation d'eau 9 de sorte à former une paroi s'étendant entre les deux parois en forme de coque 6a, 6b du réservoir d'eau 6 suite à la jonction des première et deuxième parties de ladite au moins une conduite de circulation d'eau 9 ménagées dans les première et deuxième parois en forme de coque 6a, 6b.Moreover, the lateral partition 9a of the first shell-shaped wall 6a makes it possible to extend the said at least one water circulation duct 9 so as to form a wall extending between the two shell-shaped walls 6a, 6b of the water tank 6 following the junction of the first and second parts of said at least one water circulation pipe 9 formed in the first and second shell-shaped walls 6a, 6b.

Cette paroi s'étendant entre les deux parois en forme de coque 6a, 6b du réservoir d'eau 6 peut ainsi être utilisée pour mettre en oeuvre un écoulement d'eau le long de sa face externe depuis un orifice d'entrée d'eau dans le réservoir d'eau 6 ménagé en partie supérieure du réservoir d'eau 6.This wall extending between the two shell-shaped walls 6a, 6b of the water tank 6 can thus be used to implement a flow of water along its outer face from a water inlet orifice. in the water tank 6 formed in the upper part of the water tank 6.

Ici et de manière nullement limitative, la cloison latérale 9a de la première partie de ladite au moins une conduite de circulation d'eau 9 s'étendant au-delà de sa cloison de fond 9c et jusqu'à la face interne de la première paroi en forme de coque 6a présente une épaisseur à sa base de l'ordre de 1 mm, c'est-à-dire au niveau de la jonction de la cloison latérale 9a avec la face interne de la première paroi en forme de coque 6a, et la première paroi en forme de coque 6a présente une épaisseur de l'ordre de 3,5mm.Here and in no way limiting, the side wall 9a of the first part of said at least one water circulation pipe 9 extending beyond its bottom wall 9c and up to the inner face of the first wall in the form of shell 6a has a thickness at its base of the order of 1 mm, that is to say at the junction of the side wall 9a with the inner face of the first shell-shaped wall 6a, and the first shell-shaped wall 6a has a thickness of the order of 3.5mm.

Avantageusement, la hauteur des nervures 18 de la première paroi en forme de coque 6a est variable suivant la longueur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 en fonction de l'épaisseur du réservoir d'eau 6 constitué par les première et deuxième parois en forme de coque 6a, 6b.Advantageously, the height of the ribs 18 of the first shell-shaped wall 6a is variable along the length of said at least one water circulation pipe 9, 10 formed inside the water tank 6 as a function of the thickness of water tank 6 constituted by the first and second shell-shaped walls 6a, 6b.

Ainsi, les nervures 18 de la première paroi en forme de coque 6a permettent de garantir une section d'écoulement d'eau constante de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6 quel que soit les variations de l'épaisseur du réservoir d'eau 6 suivant la longueur de ladite au moins une conduite de circulation d'eau 9, 10 ménagée à l'intérieur du réservoir d'eau 6.Thus, the ribs 18 of the first shell-shaped wall 6a make it possible to guarantee a constant water flow section of the at least one water circulation pipe 9, 10 formed inside the water tank. 6 regardless of the variations in the thickness of the water tank 6 along the length of said at least one water circulation pipe 9, 10 formed inside the water tank 6.

Dans un mode de réalisation tel qu'illustré aux figures 1, 3 et 4, la première paroi en forme de coque 6a est de forme bombée.In one embodiment as illustrated in figures 1 , 3 and 4 the first shell-shaped wall 6a is curved in shape.

La variation de la hauteur des nervures 18 de la première paroi en forme de coque 6a est particulièrement avantageuse lorsque la première paroi en forme de coque 6a du réservoir d'eau 6 est de forme bombée.The variation of the height of the ribs 18 of the first shell-shaped wall 6a is particularly advantageous when the first shell-shaped wall 6a of the water tank 6 is curved in shape.

La première paroi en forme de coque 6a peut être de forme bombée suivant la largeur et/ou la longueur du réservoir d'eau 6.The first shell-shaped wall 6a may be curved in shape along the width and / or length of the water tank 6.

Bien entendu, la forme de la première paroi en forme de coque du réservoir d'eau n'est nullement limitative et peut être différente, en particulier en forme de vagues.Of course, the shape of the first shell-shaped wall of the water tank is in no way limiting and may be different, in particular in the form of waves.

Dans un autre mode de réalisation, la première paroi en forme de coque est plane.In another embodiment, the first shell-shaped wall is planar.

Ici, la face externe de la première paroi en forme de coque 6a du réservoir d'eau 6 comprend des stries.Here, the outer face of the first shell-shaped wall 6a of the water tank 6 comprises ridges.

Ainsi, les stries de la face externe de la première paroi en forme de coque 6a du réservoir d'eau 6 permettent de masquer des imperfections esthétiques résiduelles de la première paroi en forme de coque 6a, en particulier des vagues s'étendant sur la face externe de la première paroi en forme de coque 6a ou encore des retassures.Thus, the ridges of the outer face of the first shell-shaped wall 6a of the water tank 6 make it possible to hide residual aesthetic imperfections of the first shell-shaped wall 6a, in particular waves extending on the face outer wall of the first shell-shaped wall 6a or sinkholes.

Ici, les cloisons 7c, 7d de la deuxième partie 7b de la deuxième conduite de circulation d'eau 7 ménagée à l'intérieur du réservoir d'eau 6 sont reliées respectivement directement aux faces internes des première et deuxième parois en forme de coque 6a, 6b puisque l'épaisseur de cette partie du réservoir d'eau 6 est suffisante pour ménager une section d'écoulement d'eau de la deuxième partie 7b de la deuxième conduite de circulation d'eau 7 équivalente à la section d'écoulement d'eau de la première partie 7a de la deuxième conduite de circulation d'eau 7.Here, the partitions 7c, 7d of the second part 7b of the second water circulation duct 7 formed inside the water tank 6 are respectively connected directly to the internal faces of the first and second shell-shaped walls 6a. 6b since the thickness of this portion of the water tank 6 is sufficient to provide a water flow section of the second portion 7b of the second water flow line 7 equivalent to the flow section of the water of the first part 7a of the second water circulation pipe 7.

Ainsi la liaison entre les cloisons 7c de la deuxième partie 7b de la deuxième conduite de circulation d'eau 7 ménagée à l'intérieur du réservoir d'eau 6 et la première paroi en forme de coque 6a peut être dépourvue de nervures 18.Thus the connection between the partitions 7c of the second part 7b of the second water circulation pipe 7 formed inside the water tank 6 and the first shell-shaped wall 6a may be devoid of ribs 18.

Grâce à la présente invention, les dimensions de profondeur et de largeur de ladite au moins une conduite de circulation d'eau ménagée à l'intérieur du réservoir d'eau sont indépendantes de l'épaisseur du réservoir d'eau.Thanks to the present invention, the depth and width dimensions of said at least one water circulation pipe formed inside the water tank are independent of the thickness of the water tank.

De cette manière, les nervures s'étendant entre la face interne de la première paroi en forme de coque et au moins l'une des cloisons de la première partie de ladite au moins une conduite de circulation d'eau ménagée dans la première paroi en forme de coque permettent de déterminer la profondeur et la largeur de ladite au moins une conduite de circulation d'eau de manière indépendante par rapport à l'épaisseur du réservoir d'eau.In this way, the ribs extending between the inner face of the first shell-shaped wall and at least one of the partitions of the first portion of said at least one water circulation duct formed in the first shell-shaped wall makes it possible to determine the depth and the width of the at least one water circulation duct independently with respect to the thickness of the water tank .

Bien entendu, de nombreuses modifications peuvent être apportées aux exemples de réalisation décrits précédemment sans sortir du cadre de l'invention.Of course, many modifications can be made to the embodiments described above without departing from the scope of the invention.

Ainsi, le réservoir d'eau de lavage et/ou de rinçage associé à la machine à laver pourrait être employé dans d'autres appareils électroménagers, par exemple une machine à laver la vaisselle ou une machine à laver et à sécher le linge.Thus, the washing and / or rinsing water tank associated with the washing machine could be used in other household appliances, for example a dishwashing machine or a washing and drying machine.
