Description

La présente invention concerne une machine à sécher le linge.The present invention relates to a dryer.

La présente invention concerne de manière générale une machine à sécher le linge équipée d'un réservoir dans la porte.The present invention relates generally to a laundry drying machine equipped with a tank in the door.

On connaît d'une part des réservoirs disposés dans la partie haute de la machine à sécher le linge et en face avant. Ce réservoir est disposé généralement sur un côté droite ou gauche.There are known on the one hand tanks located in the upper part of the dryer machine and on the front face. This tank is generally disposed on a right or left side.

Ce type de réservoir nécessite des tuyaux pour relier les autres organes de longueur importante et une pompe de relevage et est donc relativement coûteux.This type of tank requires hoses to connect the other long-length members and a lift pump and is therefore relatively expensive.

Par ailleurs, on connaît des réservoirs disposés en bas de la machine à sécher le linge et en face avant. Ces réservoirs sont disposés à proximité d'un condenseur.Moreover, there are known tanks located at the bottom of the dryer and the front machine. These tanks are arranged near a condenser.

Cependant, ces types de réservoirs ont l'inconvénient d'être à proximité des organes électriques de la machine à sécher le linge. Par conséquent, des moyens assurant l'étanchéité et la sécurité électrique de l'appareil doivent être mis en oeuvre et sont donc relativement coûteux. Ces réservoirs étant disposés à l'intérieur de la carrosserie, des moyens d'étanchéité et d'alimentation du circuit hydraulique commandés électriquement sont indispensables pour éviter toute fuite de liquide.However, these types of tanks have the disadvantage of being near the electrical organs of the dryer. Therefore, means ensuring the sealing and electrical safety of the apparatus must be implemented and are therefore relatively expensive. These tanks being arranged inside the bodywork, sealing means and power supply of the electrically controlled hydraulic circuit are essential to prevent any leakage of liquid.

En outre, ces réservoirs sont volumineux et nécessitent un espace important dans des zones d'une machine à sécher le linge où les organes sont nombreux et encombrants.In addition, these tanks are bulky and require significant space in areas of a dryer machine where the organs are numerous and bulky.

La présente invention a pour but de résoudre les inconvénients précités et de proposer une machine à sécher le linge comprenant un réservoir de manière à utiliser le volume inutilisé de la porte, d'assurer la sécurité de l'utilisateur en évitant tout contact de liquide avec les organes électriques. Les moyens du circuit hydraulique associés au réservoir ne nécessitent pas d'être alimentés en électricité et permettent de garantir l'étanchéité de ce dernier lors de son retrait de la porte et avec ladite porte. Les moyens du circuit hydraulique associés au réservoir permettent également d'assurer l'étanchéité entre la porte et la structure de la machine. En outre, le réservoir peut être rempli sans ouvrir la porte de la machine et par conséquent s'affranchir des risques électriques.The present invention aims to solve the aforementioned drawbacks and to provide a laundry drying machine comprising a reservoir so as to use the unused volume of the door, to ensure the safety of the user by avoiding any liquid contact with the electric organs. The hydraulic circuit means associated with the reservoir do not need to be supplied with electricity and to ensure the tightness of the latter during its removal from the door and with said door. The hydraulic circuit means associated with the reservoir also ensure sealing between the door and the structure of the machine. In addition, the tank can be filled without opening the door of the machine and therefore be free from electrical hazards.

A cet effet, la présente invention vise une machine à sécher le linge comprenant un boîtier ayant une ouverture d'accès fermée par une porte, un tambour rotatif, un réservoir comprenant un fond, un dessus et des parois périphériques, et au moins un orifice.For this purpose, the present invention is directed to a laundry drying machine comprising a housing having an access opening closed by a door, a rotating drum, a tank comprising a bottom, a top and peripheral walls, and at least one orifice .

Selon l'invention, ledit réservoir est placé dans la porte de la machine à sécher le linge, le retrait et la mise en place dudit réservoir s'effectuant au moins avec ladite porte fermée, et ledit réservoir est un réservoir de stockage d'eau relié à un générateur de vapeur par l'intermédiaire d'un circuit hydraulique.According to the invention, said tank is placed in the door of the dryer machine, the withdrawal and setting up of said tank taking place at least with said closed door, and said tank is a water storage tank connected to a steam generator via a hydraulic circuit.

Ainsi, le réservoir se loge dans la porte de la machine sans occuper de l'espace utile pour les organes de fonctionnement de ladite machine. Ledit réservoir sert à alimenter un dispositif de génération de vapeur. Le volume de la porte est un espace inutilisé permettant d'intégrer facilement le réservoir sans avoir d'incidence sur l'isolation thermique de la machine. L'isolation thermique nécessaire se loge dans un espace de faible épaisseur.Thus, the tank is housed in the door of the machine without occupying the space useful for the operating members of said machine. Said tank is used to feed a steam generating device. The volume of the door is an unused space to easily integrate the tank without affecting the thermal insulation of the machine. The necessary thermal insulation is housed in a thin space.

En outre, l'étanchéité entre le réservoir, la porte et l'intérieur de la machine est assurée par les moyens du circuit hydraulique associés audit réservoir lors de l'utilisation de ce dernier, aussi lors de la mise en place et du retrait dudit réservoir ainsi que lors du remplissage de ce dernier.In addition, the seal between the tank, the door and the inside of the machine is ensured by the means of the hydraulic circuit associated with said tank during the use of the latter, also during the introduction and removal of said tank and when filling it.

Le réservoir peut être retiré de la porte pour être rempli avec un robinet d'eau.The tank can be removed from the door to be filled with a water faucet.

L'emplacement du réservoir dans la porte permet également d'utiliser ledit réservoir comme un collecteur de liquide pouvant servir lors d'un cycle standard de la machine.The location of the tank in the door also makes it possible to use said tank as a liquid collector that can be used during a standard cycle of the machine.

Selon une caractéristique préférée de l'invention, lesdites au moins deux valves à dépression comprennent une valve supérieure et une valve inférieure.According to a preferred feature of the invention, said at least two vacuum valves comprise an upper valve and a lower valve.

De cette manière, l'étanchéité du réservoir est assurée à tout instant de son utilisation.In this way, the tightness of the tank is ensured at all times of its use.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will become apparent in the description below.

On va décrire tout d'abord en référence à la figure 1 une machine à sécher le linge conforme à l'invention.We will first describe with reference to Figure 1 a drying machine according to the invention.

Cette machine à sécher le linge 1 est du type à chargement frontal. De cette manière, cette machine 1 est adaptée à sécher le linge.This dryer 1 is of the front loading type. In this way, this machine 1 is adapted to dry the laundry.

Cette machine à sécher le linge 1 comporte une carrosserie 2 comprenant une ouverture d'accès 3 à l'intérieur de la carrosserie 2. Dans les machines à chargement frontal, cette ouverture d'accès 3 est réalisée dans une portion frontale de la carrosserie 2, et dans cet exemple, dans un plan vertical de la carrosserie 2.This dryer 1 comprises a body 2 comprising an access opening 3 inside the body 2. In the front-loading machines, this access opening 3 is formed in a front portion of the body 2 , and in this example, in a vertical plane of the bodywork 2.

Une porte d'accès 4 est adaptée à obturer cette ouverture 3 de la carrosserie 2 de la machine 1, notamment lors du fonctionnement de celle-ci.An access door 4 is adapted to close this opening 3 of the body 2 of the machine 1, especially during operation thereof.

En particulier, de manière connue, cette porte d'accès 4 est associée à des moyens de verrouillage (non représentés) dont le fonctionnement est lié au cycle de séchage de la machine 1. Ainsi, en début de cycle de séchage, les moyens de verrouillage sont actionnés pour empêcher l'ouverture de la porte d'accès 4. De manière similaire, en fin de cycle de séchage, les moyens de verrouillage sont déverrouillés pour permettre l'ouverture par l'utilisateur de la machine 1.In particular, in known manner, this access door 4 is associated with locking means (not shown) whose operation is linked to the drying cycle of the machine 1. Thus, at the beginning of the drying cycle, the means of locking are actuated to prevent the opening of the access door 4. Similarly, at the end of the drying cycle, the locking means are unlocked to allow the opening by the user of the machine 1.

Dans cet exemple de réalisation, et de manière nullement limitative, la porte d'accès 4 est montée pivotante autour d'un axe de rotation solidaire de la carrosserie 2 de la machine 1.In this embodiment, and in no way limiting, the access door 4 is pivotally mounted about an axis of rotation integral with the body 2 of the machine 1.

La carrosserie 2 de la machine 1 est adaptée à loger un tambour 6 qui est adapté notamment à contenir les pièces de linge.The body 2 of the machine 1 is adapted to accommodate a drum 6 which is adapted in particular to contain the clothes.

Le tambour 6 est ainsi monté de manière connue dans la carrosserie 2 et mobile en rotation autour d'un axe lors des différents cycles de séchage de la machine 1.The drum 6 is thus mounted in a known manner in the body 2 and rotatable about an axis during the various drying cycles of the machine 1.

Le tambour 6 est ainsi monté en rotation autour d'un axe sensiblement horizontal.The drum 6 is thus mounted in rotation about a substantially horizontal axis.

On notera que la figure 1 est schématique et que de nombreux organes nécessaires au fonctionnement de la machine (et par exemple moteur, filtres, ...) ont été omis et n'ont pas besoin d'être décrits en détail ici.Note that Figure 1 is schematic and that many organs necessary for the operation of the machine (and for example engine, filters, ...) have been omitted and do not need to be described in detail here.

On va décrire à présent le fonctionnement d'une machine à sécher le linge comprenant un réservoir pour récupérer les condensas.We will now describe the operation of a laundry drying machine comprising a reservoir for recovering the condensates.

Dans ce mode de réalisation de l'invention, le réservoir 9 est disposé dans la porte 4 de la machine à sécher le linge 1. Ledit réservoir 9 est relié au circuit de traitement de l'air et de l'eau (non représenté) de la machine à sécher le linge 1. Ledit réservoir 9 permet notamment de récupérer les condensas générées par le séchage du linge.In this embodiment of the invention, the tank 9 is disposed in the door 4 of the dryer 1. The tank 9 is connected to the air and water treatment circuit (not shown) of the drying machine 1. Said tank 9 allows in particular to recover the condensas generated by the drying of the laundry.

Ledit réservoir 9 comprend au moins un orifice 5 sur le dessus 14. Ledit au moins un orifice 5 permet de récupérer les condensas du circuit de traitement de l'air et de l'eau de la machine à sécher le linge 1 dans le réservoir 9.Said reservoir 9 comprises at least one orifice 5 on the top 14. Said at least one orifice 5 makes it possible to recover the condensates from the air and water treatment circuit of the dryer 1 in the reservoir 9 .

Par exemple, ledit au moins un orifice 5 est un moyen d'introduction et d'évacuation de liquide pour stocker les condensas.For example, said at least one orifice 5 is a liquid introduction and discharge means for storing the condensates.

Dans un autre mode de réalisation de l'invention, le réservoir 9 peut comprendre au moins une ouverture d'introduction et au moins une ouverture d'évacuation. Ainsi, les condensas récupérés dans le réservoir 9 peuvent être réutilisés dans le circuit de traitement de l'air et de l'eau de la machine à sécher le linge 1.In another embodiment of the invention, the reservoir 9 may comprise at least one introduction opening and at least one discharge opening. Thus, the condensates recovered in the tank 9 can be reused in the air and water treatment circuit of the dryer 1.

On va décrire à présent le fonctionnement d'une machine à sécher le linge comprenant un dispositif de génération de vapeur utilisant un réservoir conforme à l'invention.We will now describe the operation of a laundry drying machine comprising a steam generating device using a tank according to the invention.

Dans ce mode de réalisation de l'invention, le générateur de vapeur 8 ne nécessite pas de chauffer l'eau contenue dans le réservoir 9 de la porte 4. Le générateur de vapeur 8 comprend une chambre sous laquelle est disposée un élément chauffant et au moins un thermostat. Par conséquent, la surface chaude du générateur de vapeur 8 est la surface inférieure.In this embodiment of the invention, the steam generator 8 does not require heating the water contained in the tank 9 of the door 4. The steam generator 8 comprises a chamber under which is disposed a heating element and at the less a thermostat. Therefore, the hot surface of the steam generator 8 is the bottom surface.

Le générateur de vapeur 8 comprend au moins deux ouvertures 10 et 11 sur la partie supérieure dudit générateur de vapeur 8. Une première ouverture 10 est une pipe d'arrivée reliée au réservoir 9 de la porte 4 et par laquelle l'eau peut entrer dans la chambre du générateur de vapeur 8. Une seconde ouverture 11 est une pipe de sortie dans laquelle la vapeur peut partir vers le circuit chaud de la machine à sécher le linge 1.The steam generator 8 comprises at least two openings 10 and 11 on the upper part of said steam generator 8. A first opening 10 is an inlet pipe connected to the tank 9 of the door 4 and through which the water can enter. the steam generator chamber 8. A second opening 11 is an outlet pipe into which the steam can travel to the hot circuit of the dryer 1.

Selon un principe thermodynamique, l'eau froide introduite à l'intérieur de la chambre du générateur de vapeur 8 et sur un élément chaud vaporise. La vaporisation de l'eau à l'intérieur de la chambre de compression provoque une augmentation de pression à l'intérieur de la chambre du générateur de vapeur 8. Cette surpression explique la présence d'une pompe 12 en amont du générateur de vapeur 8.According to a thermodynamic principle, the cold water introduced inside the steam generator chamber 8 and on a hot element vaporizes. The vaporization of the water inside the compression chamber causes an increase in pressure inside the chamber of the steam generator 8. This overpressure explains the presence of a pump 12 upstream of the steam generator 8 .

Selon les expériences menées par la Demanderesse, ces dernières ont permis de mettre en évidence que la pression générée par la différence de hauteur entre le réservoir 9 de la porte 4 et le générateur de vapeur 8, mesurée par exemple en hauteur de colonne d'eau, n'est pas suffisante pour dépasser la surpression due à la vaporisation de l'eau dans la chambre du générateur de vapeur 8.According to the experiments carried out by the Applicant, the latter have made it possible to demonstrate that the pressure generated by the difference in height between the tank 9 of the door 4 and the steam generator 8, measured for example in the height of the water column is not sufficient to exceed the overpressure due to the vaporization of the water in the steam generator chamber 8.

Ainsi, une pompe 12 est nécessaire pour assurer l'alimentation en eau du générateur de vapeur 8 et avec un flux constant.Thus, a pump 12 is necessary to ensure the water supply of the steam generator 8 and with a constant flow.

Dans un autre mode de réalisation de l'invention, le générateur de vapeur 8 peut être remplacé par un autre type de générateur tel qu'un tube chauffant. En revanche, l'utilisation d'une pompe 12 est nécessaire, celle-ci est la même quelque soit le type de générateur de vapeur 8.In another embodiment of the invention, the steam generator 8 may be replaced by another type of generator such as a heating tube. However, the use of a pump 12 is necessary, it is the same regardless of the type of steam generator 8.

On a illustré de manière isolée sur les figures 11 à 14, les moyens du circuit hydraulique associés au réservoir conforme à l'invention.FIGS. 11 to 14 illustrate in isolation the means of the hydraulic circuit associated with the tank according to the invention.

Le réservoir 9 est dans la porte 4, des moyens du circuit hydraulique 16 étant associés audit réservoir 9, lesdits moyens du circuit hydraulique 16 comprenant au moins deux valves 34 et un moyen d'aspiration, dont au moins une valve 34 étant une valve à dépression 39.The reservoir 9 is in the door 4, means of the hydraulic circuit 16 being associated with said reservoir 9, said means of the hydraulic circuit 16 comprising at least two valves 34 and a suction means, at least one valve 34 being a valve depression 39.

Le moyen d'aspiration est une pompe 12.The suction means is a pump 12.

Comme décrit précédemment, une pompe 12 est nécessaire au fonctionnement du générateur de vapeur 8. Ainsi, le fonctionnement de ce dispositif hydraulique permet l'utilisation d'au moins une valve à dépression 34.As previously described, a pump 12 is necessary for the operation of the steam generator 8. Thus, the operation of this hydraulic device allows the use of at least one vacuum valve 34.

Ladite au moins une valve à dépression 39 ne nécessite pas de pièces d'étanchéité males et femelles à engager l'une dans l'autre. Par conséquent, les moyens du circuit hydraulique 16 associés au réservoir 9 nécessitent moins de précision et moins d'efforts à exercer.Said at least one vacuum valve 39 does not require parts male and female seals to engage one into the other. Therefore, the hydraulic circuit means 16 associated with the reservoir 9 require less precision and less effort to exert.

Ladite au moins une valve à dépression 39 nécessite une précision moindre pour le positionnement de celle-ci avec les éléments constituant le dispositif hydraulique de la machine 1.Said at least one vacuum valve 39 requires less precision for positioning it with the elements constituting the hydraulic device of the machine 1.

Dans un mode de réalisation de l'invention, les moyens du circuit hydraulique 16 peuvent comprendre une seule valve à dépression 39. Les moyens du circuit hydraulique 16 comprenant au moins deux valves 34 peuvent comprendre une seconde valve classique.In one embodiment of the invention, the means of the hydraulic circuit 16 may comprise a single vacuum valve 39. The means of the hydraulic circuit 16 comprising at least two valves 34 may comprise a second conventional valve.

Dans un autre mode de réalisation de l'invention, les moyens du circuit hydraulique 16 peuvent comprendre deux valves à dépression 35 et 39In another embodiment of the invention, the means of the hydraulic circuit 16 may comprise two vacuum valves 35 and 39

Les moyens du circuit hydraulique 16 associés au réservoir 9 comprennent une valve supérieure 35 disposée dans le réservoir 9 comprenant au moins un joint 36, un ressort 37 et un piston 38. Les moyens du circuit hydraulique associés au réservoir 9 comprennent également une valve inférieure 39 comprenant au moins un joint 40, un ressort 41 et un piston 42.The hydraulic circuit means 16 associated with the reservoir 9 comprise an upper valve 35 disposed in the reservoir 9 comprising at least one seal 36, a spring 37 and a piston 38. The hydraulic circuit means associated with the reservoir 9 also comprise a lower valve 39 comprising at least one seal 40, a spring 41 and a piston 42.

Les moyens du circuit hydraulique 16 associés au réservoir 9 sont aussi pourvus d'une pièce de connexion 43 s'étendant d'un évidement 18 de la porte 4 à une partie de la structure de la machine à sécher le linge 1.The means of the hydraulic circuit 16 associated with the reservoir 9 are also provided with a connecting piece 43 extending from a recess 18 of the door 4 to a part of the structure of the dryer 1.

La valve supérieure 35 est intégrée dans le réservoir 9 de la porte 4. Ladite valve supérieure 35 permet de contenir le liquide dans le réservoir 9 sans qu'une fuite ne soit possible lors du retrait du réservoir 9 de la porte 4. De cette manière, le réservoir 9 peut être rempli à un robinet.The upper valve 35 is integrated in the reservoir 9 of the door 4. Said upper valve 35 can contain the liquid in the tank 9 without leakage is possible when removing the reservoir 9 of the door 4. In this way , the tank 9 can be filled at a tap.

La valve inférieure 39 est intégrée à la pièce de connexion 43 disposée dans la porte 4 de la machine à sécher le linge 1. De cette manière, lors de l'ouverture de la porte 4 contenant le réservoir 9 aucune fuite de liquide n'est possible de la pièce de connexion 43.The lower valve 39 is integrated in the connecting piece 43 disposed in the door 4 of the dryer 1. In this way, when opening the door 4 containing the reservoir 9, no leakage of liquid is possible from the connection piece 43.

Les moyens du circuit hydraulique 16 comprennent également une membrane 44 pour assurer une connexion correcte entre la porte 4 et un tuyau 45 alimentant la pompe 12.The means of the hydraulic circuit 16 also comprise a membrane 44 to ensure a correct connection between the door 4 and a pipe 45 supplying the pump 12.

Ladite membrane 44 permet de positionner la pièce de connexion 43 avec une précision horizontale et verticale moins importante par rapport au tuyau 45 d'alimentation de la pompe 12 pour assurer l'étanchéité.Said membrane 44 makes it possible to position the connecting piece 43 with a smaller horizontal and vertical precision with respect to the supply pipe 45 of the pump 12 in order to seal.

Le diamètre intérieur d'une ouverture ménagée dans la pièce de connexion 43 est plus petit que le diamètre de l'ouverture ménagée dans la membrane 44.The inside diameter of an opening in the connecting piece 43 is smaller than the diameter of the opening in the membrane 44.

En outre, la membrane 44 est souple de sorte que l'effort pour introduire la pièce de connexion 43 à l'intérieur de ladite membrane 44 est faible.In addition, the membrane 44 is flexible so that the effort to introduce the piece connection 43 within said membrane 44 is weak.

Dans ce mode de réalisation de l'invention illustré aux figures 11 à 14, les deux valves à dépression 35 et 39 fonctionnent par dépression.In this embodiment of the invention illustrated in Figures 11 to 14, the two vacuum valves 35 and 39 operate by depression.

Chaque valve à dépression 35 et 39 comprend respectivement un ressort 37 et 41 disposé sur une face opposée à un joint d'étanchéité 36 et 40.Each vacuum valve 35 and 39 respectively comprises a spring 37 and 41 disposed on a face opposite to a seal 36 and 40.

Pour permettre l'ouverture d'une valve à dépression 39, le piston 42 est déplacé par une force de sens opposée et supérieure à la force exercée par le ressort 41.To allow the opening of a vacuum valve 39, the piston 42 is displaced by a force of opposite direction and greater than the force exerted by the spring 41.

Lors de la mise en fonctionnement de la pompe 12 d'alimentation du générateur de vapeur 8, ladite pompe 12 tend à aspirer l'eau contenue dans un tuyau d'arrivée 43 à la valve inférieure 39 via un raccord souple 45 reliant la partie fixe de la machine 1 à la porte 4. L'aspiration générée par la pompe 12 permet de créer la dépression nécessaire au déplacement du piston 42 de la valve inférieure 39.When the steam generator feeding pump 12 is put into operation, said pump 12 tends to suck the water contained in an inlet pipe 43 to the lower valve 39 via a flexible coupling 45 connecting the fixed part. from the machine 1 to the door 4. The suction generated by the pump 12 creates the depression necessary for the displacement of the piston 42 of the lower valve 39.

Le piston 42 de la valve inférieure 39 se déplace en premier. La pression au dessus du piston 42 de la valve inférieure 39 tend à être supérieure ou égale à la pression à l'intérieur du tuyau d'arrivée 43 de la valve inférieure 39. Ainsi, une dépression est créée et permet le déplacement du piston 38 de la valve supérieure 35. Le fonctionnement de la valve supérieure 35 est similaire au fonctionnement de la valve inférieure 39.The piston 42 of the lower valve 39 moves first. The pressure above the piston 42 of the lower valve 39 tends to be greater than or equal to the pressure inside the inlet pipe 43 of the lower valve 39. Thus, a vacuum is created and allows the piston 38 to move. of the upper valve 35. The operation of the upper valve 35 is similar to the operation of the lower valve 39.

Par conséquent, l'eau contenue dans le réservoir 9 est à présent aspirée dans un premier temps entre les deux valves à dépression 35 et 39 puis dans le tuyau de raccordement 45 conduisant à la pompe 12.Consequently, the water contained in the tank 9 is now sucked firstly between the two vacuum valves 35 and 39 and then in the connection pipe 45 leading to the pump 12.

Dès l'arrêt de la mise en fonctionnement de la pompe 12, les pressions aux différents points du circuit hydraulique associé au réservoir 9 s'équilibrent et les valves à dépression 35 et 39 reviennent respectivement dans leur position initiale.As soon as the pump 12 is put into operation, the pressures at the various points of the hydraulic circuit associated with the reservoir 9 are balanced and the vacuum valves 35 and 39 return to their initial position respectively.

Les ressorts 37 et 41 des valves à dépression 35 et 39 sont dimensionnés en fonction de la hauteur de la colonne d'eau maximum que lesdits ressorts 37 et 41 peuvent supporter. Dans le cas de la valve inférieure 39, la hauteur de colonne d'eau maximum correspond à la longueur du raccord 45 reliant ladite valve inférieure 39 à la partie fixe sur la machine 1 permettant de contenir l'eau lorsque la porte 4 est ouverte. Et concernant la valve supérieure 35, la hauteur de colonne d'eau maximum correspond à la hauteur de colonne d'eau contenue dans le réservoir 9. La raideur du ressort 37 est calculée notamment pour un réservoir 9 en dehors de l'évidement 18 de la porte 4 et que ledit réservoir 9 est plein.The springs 37 and 41 of the vacuum valves 35 and 39 are sized according to the height of the maximum water column that said springs 37 and 41 can support. In the case of the lower valve 39, the maximum water column height corresponds to the length of the connector 45 connecting said lower valve 39 to the fixed part on the machine 1 for containing the water when the door 4 is open. And concerning the upper valve 35, the maximum water column height corresponds to the height of the water column contained in the reservoir 9. The stiffness of the spring 37 is calculated in particular for a reservoir 9 outside the recess 18 of the door 4 and said tank 9 is full.

On va décrire à présent les moyens permettant de visualiser le niveau de liquide dans le réservoir conforme à l'invention.We will now describe the means for viewing the liquid level in the tank according to the invention.

Le réservoir 9 comprend au moins un moyen indicateur 46 de niveau de liquide.The reservoir 9 comprises at least one indicator means 46 of liquid level.

Le réservoir 9 est au moins en partie transparent.The reservoir 9 is at least partly transparent.

Dans un mode de réalisation de l'invention, la zone transparente du réservoir 9 peut s'étendre du bas vers le haut dudit réservoir 9 et d'une largeur de l'ordre de 2 centimètres.In one embodiment of the invention, the transparent zone of the reservoir 9 can extend from the bottom to the top of said tank 9 and a width of the order of 2 centimeters.

Dans un autre mode de réalisation de l'invention, la zone transparente du réservoir 9 peut s'étendre sur toute la largeur dudit réservoir 9 de manière à visualiser le contenu global.In another embodiment of the invention, the transparent zone of the reservoir 9 can extend over the entire width of said reservoir 9 so as to display the overall content.

Le moyen indicateur de niveau de liquide peut comprendre au moins un voyant lumineux.The liquid level indicator means may comprise at least one indicator light.

Bien entendu, la présente invention n'est pas limitée aux exemples de réalisation décrits précédemment.Of course, the present invention is not limited to the embodiments described above.
