Description

La présente invention concerne une machine à sécher le linge à condensation ayant un recyclage de l'eau de condensas pour l'alimentation d'un générateur de vapeur.The present invention relates to a dryer for condensing laundry having a recycle of condensate water for supplying a steam generator.

Elle concerne également un procédé d'alimentation en eau de condensas pour la génération de vapeur d'une machine à sécher le linge à condensation comprenant un générateur de vapeur.It also relates to a method of supplying condensate water for the steam generation of a condensation dryer machine comprising a steam generator.

De manière générale, la présente invention concerne le domaine de la génération de vapeur et vise à générer de la vapeur au cours d'un programme de défroissage du linge à partir de l'eau de condensas recyclée dans un bac de stockage.In general, the present invention relates to the field of steam generation and aims to generate steam during a laundry program from the condensate water recycled in a storage bin.

La présente invention vise ainsi à alimenter un générateur de vapeur avec de l'eau de condensas stockée dans un bac interne à la machine à sécher le linge à condensation pour générer de la vapeur.The present invention thus aims to supply a steam generator with condensate water stored in an internal tray to the dryer machine to generate steam to generate steam.

On connaît des machines à sécher le linge à condensation équipées d'un générateur de vapeur. Ledit générateur de vapeur est alimenté en eau du réseau. La machine à sécher le linge à condensation comprend un générateur de vapeur alimenté par de l'eau du réseau provenant d'un bac. Au cours d'un programme de défroissage du linge, la vapeur produite par le générateur de vapeur est introduite dans un tambour pour humidifier le linge.There are known machines for drying condensation laundry equipped with a steam generator. Said steam generator is supplied with mains water. The condensing dryer comprises a steam generator supplied with mains water from a tank. During a laundry program, the steam produced by the steam generator is introduced into a drum to moisten the laundry.

Cependant, ces machines à sécher le linge présentent l'inconvénient qu'une couche de matière contenue dans l'eau se dépose sur la surface interne du générateur de vapeur au cours de la génération de vapeur. Le dépôt de ladite couche, pouvant comprendre au moins du calcaire, dégrade le fonctionnement du générateur de vapeur et entraînant la réduction du débit de vapeur, voire le bouchage de ce dernier. Par conséquent, le générateur de vapeur ne peut plus produire l'effet de défroissage du linge et un dysfonctionnement électrique de la machine à sécher le linge peut survenir. Les performances de la machine à sécher le linge sont diminuées au cours de l'utilisation du générateur de vapeur et des dysfonctionnements électriques peuvent endommager ladite machine.However, these laundry drying machines have the disadvantage that a layer of material contained in the water is deposited on the internal surface of the steam generator during the steam generation. Deposition of said layer, which may include at least limestone, degrades the operation of the steam generator and causing the reduction of the steam flow, or even the clogging thereof. As a result, the steam generator can no longer produce the laundry wrinkle effect and electrical malfunction of the dryer may occur. The performance of the dryer is reduced during use of the steam generator and electrical malfunctions can damage the machine.

Par ailleurs, ces machines à sécher le linge à condensation présentent l'inconvénient d'obliger l'utilisateur à remplir un bac d'alimentation du générateur de vapeur.Moreover, these clothes drying machines with condensation have the disadvantage of requiring the user to fill a steam generator supply tray.

En outre, ces machines à sécher le linge à condensation nécessitent un bac supplémentaire pour alimenter le générateur de vapeur en eau. Par conséquent, le coût d'obtention d'une telle machine est plus élevé.In addition, these condensing clothes drying machines require an additional tray to supply the steam generator with water. Therefore, the cost of obtaining such a machine is higher.

Le remplissage du bac supplémentaire pour l'alimentation du générateur de vapeur en eau peut nécessiter l'utilisation d'une eau déminéralisée afin de ne pas entartrer ledit générateur de vapeur. Par conséquent, le coût d'utilisation d'une telle machine à sécher le linge est onéreux.The filling of the additional tank for supplying the steam generator with water may require the use of demineralized water so as not to calcuate said steam generator. Therefore, the cost of using such a dryer is expensive.

On connaît également un document US 2006/112585 A1 qui décrit une machine à sécher le linge combinée capable de mettre en circulation de l'air en continu dans un tambour de séchage et dans une enceinte de séchage de sorte à sécher le linge et capable d'introduire dans le circuit de circulation d'air de la vapeur générée à partir d'eau de condensas de sorte à mettre en oeuvre un cycle de rafraîchissement du linge en utilisant de l'eau.A document is also known US 2006/112585 A1 which describes a combined clothes drying machine capable of continuously circulating air in a drying drum and in a drying chamber so as to dry the laundry and capable of introducing into the air circulation circuit steam generated from condensate water so as to implement a laundry refresh cycle using water.

La présente invention a pour but d'alimenter avec de l'eau de condensas le générateur de vapeur d'une machine à sécher le linge à condensation à partir d'une eau de condensas stockée dans un bac interne de ladite machine. Ladite eau de condensas est obtenue à partir des programmes de séchage précédents au cours desquels l'humidité du linge a été condensée dans le circuit de séchage de la machine.The present invention aims to supply with condensate water the steam generator of a dryer machine to condensation from a condensate water stored in an internal tray of said machine. Said condensate water is obtained from previous drying programs in which the moisture of the laundry has been condensed in the drying circuit of the machine.

En outre, l'eau de condensas évite le dépôt d'une couche à l'intérieur du générateur de vapeur nécessitant une opération de détartrage régulière.In addition, the condensate water prevents the deposition of a layer inside the steam generator requiring a regular descaling operation.

A cet effet, la présente invention vise une machine à sécher le linge à condensation comprenant un générateur de vapeur, une pompe de relevage reliée en aval à un bac mobile de récupération d'eau de condensas et en amont à un bac intermédiaire, ledit bac intermédiaire étant relié d'autre part à un circuit de séchage comprenant un condenseur.For this purpose, the present invention is directed to a machine for drying the condensing laundry comprising a steam generator, a lifting pump connected downstream to a mobile condensate water collection tank and upstream to an intermediate ferry, said ferry intermediate being connected on the other hand to a drying circuit comprising a condenser.

Selon l'invention, le bac mobile de récupération d'eau de condensas alimente en eau de condensas le générateur de vapeur et le bac mobile de récupération d'eau de condensas comprend un dispositif de trop plein déversant le surplus d'eau de condensas dans le bac intermédiaire.According to the invention, the mobile condensate water collecting tank supplies condensate water to the steam generator and the mobile condensate water collection tank comprises an overflow device discharging the excess condensate water into the condensate water tank. the intermediate tray.

Ainsi, la machine à sécher le linge à condensation permet d'alimenter un générateur de vapeur avec de l'eau de condensas stockée dans un bac mobile à un coût minimum.Thus, the dryer machine for condensation allows to feed a steam generator with condensate water stored in a mobile container at a minimum cost.

La présente invention permet de disposer d'une réserve d'eau interne à la machine à sécher le linge à condensation pour stocker de l'eau de condensas dans un bac mobile de récupération d'eau de condensas. Le bac mobile de récupération d'eau de condensas peut être rempli par la pompe de relevage pour alimenter un générateur de vapeur afin de générer de la vapeur. La génération de vapeur est réalisée au moindre coût par l'utilisation d'eau de condensas provenant des programmes de séchage du linge précédents.The present invention makes it possible to have a water reserve internal to the dryer for condensing laundry to store condensate water in a mobile tank for the recovery of condensate water. The mobile condensate drain pan can be filled by the lift pump to feed a steam generator to generate steam. Steam generation is achieved at the least cost by using condensate water from previous laundry drying programs.

L'eau de condensas ne peut déborder du bac mobile de récupération d'eau de condensas lors du relevage de l'eau de condensas par la pompe de relevage depuis le bac intermédiaire vers ledit bac mobile.Condensate water can not overflow the mobile condensate drain tray when the condensate water is raised by the lift pump from the intermediate tank to the said mobile container.

Le surplus d'eau de condensas du bac mobile de récupération d'eau de condensas est déversé dans le bac intermédiaire dès que la conduite d'alimentation en eau de condensas du générateur de vapeur et que ledit bac mobile sont remplis.The excess condensate water from the mobile condensate drain tray is discharged into the intermediate tank as soon as the feed pipe condensate water from the steam generator and that said movable tank are filled.

Le dispositif de trop plein permet de garantir le bon fonctionnement de la machine à sécher le linge à condensation et d'éviter tout débordement d'eau de condensas d'une réserve d'eau de condensas.The overflow device ensures the proper functioning of the machine to dry the condensing laundry and to avoid any overflow of condensate water from a condensate water reserve.

Selon une caractéristique préférée de l'invention, le bac mobile de récupération d'eau de condensas comprend un dispositif de connexion coopérant avec une conduite d'alimentation du générateur de vapeur.According to a preferred feature of the invention, the mobile tank for condensate water recovery comprises a connection device cooperating with a feed pipe of the steam generator.

Ainsi, ce dispositif de connexion entre le bac mobile de récupération d'eau de condensas et la conduite d'alimentation du générateur de vapeur permet d'assurer l'étanchéité pour l'alimentation du générateur de vapeur en eau de condensas.Thus, this connection device between the mobile tank for condensate water recovery and the supply line of the steam generator makes it possible to ensure the seal for supplying the steam generator with condensate water.

En outre, ce dispositif de connexion permet de maintenir en position le bac mobile de récupération d'eau de condensas par rapport à la conduite d'alimentation du générateur de vapeur.In addition, this connection device makes it possible to hold the mobile condensate water collection tray in position relative to the feed pipe of the steam generator.

Selon une autre caractéristique préférée de l'invention, le dispositif de connexion coopérant avec une conduite d'alimentation du générateur de vapeur comprend une pipe pour l'aspiration de l'eau de condensas à l'intérieur du bac mobile de récupération de condensas, l'aspiration de l'eau de condensas étant produite par une pompe d'alimentation dudit générateur de vapeur.According to another preferred feature of the invention, the connection device cooperating with a feed pipe of the steam generator comprises a pipe for the suction of the condensate water inside the mobile condensate recovery tray, the suction of the condensate water being produced by a feed pump of said steam generator.

Ainsi, la pipe du dispositif de connexion permet d'aspirer de l'eau de condensas dans le fond du bac mobile de récupération d'eau de condensas. De cette manière, le générateur de vapeur est alimenté sans interruption lors de la mise en en fonctionnement de la pompe d'alimentation dudit générateur de vapeur.Thus, the pipe of the connection device makes it possible to draw condensate water into the bottom of the mobile tank for the recovery of condensate water. In this way, the steam generator is fed continuously during the putting into operation of the feed pump of said steam generator.

La pompe d'alimentation du générateur de vapeur aspire de l'eau de condensas du bac mobile de récupération d'eau de condensas au travers de la pipe connectée au dispositif de connexion puis par la conduite d'alimentation dudit générateur de vapeur connectée également au dispositif de connexion.The feed pump of the steam generator draws condensate water from the condensate water collecting tray through the pipe connected to the connection device and then through the supply line of said steam generator connected to the connection device.

L'alimentation du générateur de vapeur est réalisée de manière étanche par le dispositif de connexion reliant la pipe et la conduite d'alimentation au travers du bac mobile de récupération d'eau de condensas.The supply of the steam generator is sealed by the connection device connecting the pipe and the supply pipe through the mobile tank for collecting condensate water.

Selon un second aspect de l'invention, elle concerne un procédé d'alimentation en eau de condensas pour la génération de vapeur d'une machine à sécher le linge à condensation comprenant au moins les étapes suivantes :

  • une première étape de remplissage en eau de condensas du bac mobile de récupération d'eau de condensas par une pompe de relevage ;
  • une deuxième étape d'alimentation en eau de condensas du générateur de vapeur par l'eau de condensas accumulée dans le bac mobile de récupération d'eau de condensas, et
  • une étape de déversement du surplus d'eau de condensas du bac mobile de récupération d'eau de condensas dans le bac intermédiaire.
According to a second aspect of the invention, it relates to a method of supplying condensate water for the steam generation of a condensing laundry machine comprising at least the following steps:
  • a first condensate water filling step of the mobile tank for the recovery of condensate water by a lifting pump;
  • a second step of supplying condensate water from the steam generator by the condensate water accumulated in the mobile condensate drain pan, and
  • a step of pouring the excess condensate water from the mobile condensate drain tray into the intermediate tray.

Ainsi, le générateur de vapeur est alimenté en eau de condensas pour générer de la vapeur au moindre coût et en évitant les problèmes d'entartrage dudit générateur de vapeur par l'eau. L'eau de condensas alimentant le générateur de vapeur est distillée et par conséquent contient peu de matière pouvant se déposer sur la surface intérieure dudit générateur de vapeur.Thus, the steam generator is supplied with condensate water to generate steam at the lowest cost and avoiding scaling problems of said steam generator with water. The condensate water supplying the steam generator is distilled and therefore contains little material that can be deposited on the inner surface of said steam generator.

Ce procédé permet de recycler l'eau de condensas pour la génération de vapeur avant de vider le bac mobile de récupération d'eau de condensas en dehors de la machine à sécher le linge à condensation. Des économies d'eau sont ainsi réalisées en utilisant un tel procédé d'alimentation d'un générateur de vapeur et l'utilisation d'eau de condensas permettant de maintenir en bon état de fonctionnement le générateur de vapeur au cours de la durée de vie de la machine à sécher le linge à condensation.This process recycles the condensate water for the steam generation before emptying the mobile condensate drain tray outside the dryer. Water savings are thus achieved by using such a method of supplying a steam generator and the use of condensate water to maintain the steam generator in good working condition during the service life. of the dryer for condensation.

A first air circuit is commonly called hot air circuit 4 and a second air circuit called cold air circuit 5.

Le circuit d'air chaud 4 est en boucle fermée et l'air chauffé par au moins un élément chauffant 6. L'air chauffé traverse le linge contenu dans le tambour 2 et l'air chauffé se charge de l'humidité contenue par le linge. Lors de cette phase, l'air est refroidi d'une température de l'ordre de 110°C à une température de l'ordre de 70°C.The hot air circuit 4 is in a closed loop and the air heated by at least one heating element 6.

L'air chauffé et humide traverse un filtre 7 placé à une sortie d'évacuation du tambour 2 pour récupérer les peluches contenues dans ledit air chauffé et humide. Un ventilateur 8 fait circuler l'air chaud et humide à l'intérieur d'un condenseur 9. L'air chaud et humide est refroidi dans des tubes du condenseur 9 et l'humidité de l'air est condensée. Le condenseur 9 est refroidi par échange de chaleur avec de l'air ambiant. Puis, l'air est de nouveau chauffé par ledit au moins un élément chauffant 6.The heated and moist air passes through a filter 7 placed at a discharge outlet of the drum 2 to recover the lint contained in said heated and moist air. A fan 8 circulates the hot and humid air inside a condenser 9. The hot and humid air is cooled in tubes of the condenser 9 and the humidity of the air is condensed. The condenser 9 is cooled by heat exchange with ambient air. Then, the air is again heated by the at least one heating element 6.

La machine à sécher le linge à condensation 1 peut également être pourvue d'un condenseur 9 à plaques à la place d'un condenseur 9 à tubes.The condensing dryer 1 may also be provided with a plate condenser 9 instead of a condenser 9 with tubes.

Le circuit d'air froid 5 est en circuit ouvert où de l'air ambiant est aspiré par un ventilateur 10 à l'arrière de la machine à sécher le linge 1.

Ledit moteur 11 peut également entraîner les deux ventilateurs 8 et 10.A motor 11 allows the driving of the drum 2 for brewing the laundry with an alternating rotation to prevent the knotting of the laundry. Said motor 11 can also drive the two fans 8 and 10.

Les deux ventilateurs 8 et 10 sont de technologie centrifuge. Le débit d'air est plus important dans un sens dit positif par rapport à un sens inversé dit négatif. Le facteur de débit d'air entre le sens positif et le sens négatif des ventilateurs 8 et 10 est sensiblement de l'ordre de 3.Both fans 8 and 10 are centrifugal technology. The air flow is greater in a positive direction relative to a reverse direction said negative. The air flow factor between the positive direction and the negative direction of the fans 8 and 10 is substantially of the order of 3.

La conduite 25 de circulation d'eau de condensas débouche dans une ouverture 31 ménagée dans le bac mobile de récupération d'eau de condensas 22. Ladite ouverture 31 peut être située dans une paroi supérieure 32 du bac mobile de récupération d'eau de condensas 22.The link between the lifting pump 21 and the mobile condensate drain tray 22 is provided by a condensate water circulation pipe 25. The condensate water circulation conduit 25 opens into an opening 31 formed in the mobile condensate water collection tray 22. Said opening 31 can be located in an upper wall 32 of the mobile condensate water collection tray 22.

La présente invention permet de disposer d'une réserve d'eau interne à la machine à sécher le linge à condensation 1 pour stocker de l'eau de condensas dans un bac mobile de récupération d'eau de condensas 22. Le bac mobile de récupération d'eau de condensas 22 peut être rempli par la pompe de relevage 21 pour alimenter un générateur de vapeur 12 afin de générer de la vapeur. La génération de vapeur est réalisée au moindre coût par l'utilisation d'eau de condensas provenant des programmes de séchage du linge précédents.The present invention makes it possible to have an internal water reserve for the dryer 1 to store condensate water in a mobile condensate water collection tray 22.

Le dispositif de connexion 27 coopérant avec une conduite 26 d'alimentation du générateur de vapeur 12 en eau de condensas comprend une pipe 28 pour l'aspiration de l'eau de condensas à l'intérieur du bac mobile de récupération de condensas 22.The connection device 27 cooperating with a conduit 26 for supplying the steam generator 12 with condensate water comprises a pipe 28 for the suction of the condensate water inside the mobile condensate recovery tray 22.

L'aspiration de l'eau de condensas est produite par une pompe d'alimentation 20 dudit générateur de vapeur 12.The suction of the condensate water is produced by a feed pump 20 of said steam generator 12.

Ainsi, la pipe du dispositif de connexion 27 permet d'aspirer de l'eau de condensas dans le fond du bac mobile de récupération d'eau de condensas 22. De cette manière, le générateur de vapeur 12 est alimenté sans interruption lors de la mise en fonctionnement de la pompe d'alimentation 20 dudit générateur de vapeur 12.Thus, the pipe of the connection device 27 makes it possible to draw condensate water into the bottom of the mobile condensate water collection tank 22. In this way, the steam generator 12 is fed continuously during the operating the feed pump 20 of said steam generator 12.

La pompe d'alimentation 20 du générateur de vapeur 12 aspire de l'eau de condensas du bac mobile de récupération d'eau de condensas 22 au travers de la pipe 28 connectée au dispositif de connexion 27 puis par la conduite d'alimentation 26 dudit générateur de vapeur 12 connectée également au dispositif de connexion 27.The feed pump 20 of the steam generator 12 draws condensate water from the mobile condensate drain tray 22 through the pipe 28 connected to the connection device 27 and then via the feed pipe 26 of the steam generator 12 also connected to the connection device 27.

L'alimentation du générateur de vapeur 12 est réalisée de manière étanche par le dispositif de connexion 27 reliant la pipe 28 et la conduite 26 d'alimentation au travers du bac mobile de récupération d'eau de condensas 22.The supply of the steam generator 12 is made in a sealed manner by the connection device 27 connecting the pipe 28 and the supply pipe 26 through the mobile condensate water collection tray 22.

Le dispositif de connexion 27 peut être fixé sur une paroi latérale du bac mobile de récupération d'eau de condensas 22 afin de relier la conduite 26 audit bac mobile 22.The connection device 27 can be fixed on a side wall of the mobile condensate water collection tray 22 in order to connect the conduit 26 to said movable tray 22.

Le dispositif de connexion 27 comprend une première ouverture pour insérer la conduite 26 d'alimentation en eau de condensas le générateur de vapeur 12 et une seconde ouverture pour insérer la pipe 28 d'aspiration d'eau de condensas dans le bac mobile 22.The connection device 27 comprises a first opening for inserting the condensate water supply pipe 26 the steam generator 12 and a second opening for inserting the condensate water suction pipe 28 into the mobile tank 22.

Les deux ouvertures du dispositif de connexion 27 sont reliées par une canalisation en forme de coude. La première ouverture du dispositif de connexion 27 est en regard d'une paroi latérale du bac mobile 22. Et la seconde ouverture du dispositif de connexion 27 est dirigée vers le bas pour aspirer l'eau de condensas par la pipe 28 au fond du bac mobile 22.The two openings of the connection device 27 are connected by a pipe in the shape of a bend. The first opening of the connection device 27 is opposite a side wall of the movable tray 22. And the second opening of the connection device 27 is directed downwards to suck the condensate water through the pipe 28 at the bottom of the tray mobile 22.

La pipe 28 s'étend dans une direction sensiblement verticale pour aspirer l'eau de condensas. La pipe 28 est placée entre la paroi supérieure 32 et la paroi de fond 33 du bac mobile 22.The pipe 28 extends in a substantially vertical direction to suck the condensate water. The pipe 28 is placed between the upper wall 32 and the bottom wall 33 of the movable tray 22.

Préférentiellement, le bac mobile de récupération de condensas 22 est placé en partie supérieure de ladite machine à sécher le linge à condensation 1.Preferably, the mobile condensate recovery tray 22 is placed in the upper part of said dryer 1.

Ainsi, le bac mobile de récupération de condensas 22 en partie supérieure de la machine 1 sert de réserve d'eau de condensas pour alimenter le générateur de vapeur 12 au cours d'un programme de défroissage du linge.Thus, the movable condensate recovery tray 22 in the upper part of the machine 1 serves as a supply of condensate water to supply the steam generator 12 during a laundry program.

Le bac mobile de récupération de condensas 22 est placé au-dessus de la pompe d'alimentation 20 du générateur de vapeur 12 pour nécessiter une faible puissance de ladite pompe d'alimentation 20. Ladite pompe d'alimentation 20 permet d'amorcer la circulation d'eau de condensas dans la conduite 26 depuis le bac mobile 22.The mobile condensate recovery tray 22 is placed above the feed pump 20 of the steam generator 12 to require a low power of said feed pump 20. Said feed pump 20 is used to start the circulation of condensate water in the pipe 26 from the mobile container 22.

Avantageusement, le bac mobile de récupération de condensas 22 est rempli en eau de condensas au cours d'un programme de séchage précédent.Advantageously, the mobile condensate recovery tray 22 is filled with condensate water during a previous drying program.

Lors des programmes de séchage précédents utilisant peu ou pas le générateur de vapeur 12, l'eau de condensas s'accumule dans le bac intermédiaire 24. Ensuite, l'eau de condensas est remontée dans le bac mobile de récupération d'eau de condensas 22 par la pompe de relevage 21. Ladite eau de condensas est recyclée pour alimenter le générateur de vapeur 12 afin de générer de la vapeur et d'introduire ladite vapeur dans le circuit de séchage 4 pour défroisser le linge contenu dans le tambour 2 de la machine 1.In previous drying programs using little or no steam generator 12, the condensate water accumulates in the intermediate tank 24. Then, the condensate water is raised in the mobile tank of condensate water 22 by the lifting pump 21. Said condensate water is recycled to feed the steam generator 12 to generate steam and to introduce said steam into the drying circuit 4 to straighten the laundry contained in the drum 2 of the machine 1.

Lorsque les deux bacs 22 et 24 sont pleins d'eau de condensas, l'utilisateur peut vider le bac mobile de récupération d'eau de condensas 22 ou encore réaliser un programme utilisant la génération de vapeur afin de faire baisser le niveau d'eau de condensas dans ledit bac mobile 22.When the two tanks 22 and 24 are full of condensate water, the user can empty the mobile condensate drain tray 22 or perform a program using the steam generation to lower the water level of condensas in said movable tray 22.

Le bac mobile de récupération d'eau de condensas 22 peut être équipé d'une ouverture obturée par un bouchon et ménagée en partie avant dudit bac mobile 22. De cette manière, le bac mobile 22 peut être rempli sur la machine 1. Le bac mobile 22 est extrait partiellement du support 34.The mobile condensate drain tray 22 can be equipped with an opening closed off by a stopper and arranged in the front part of said movable tray 22. In this way, the movable tray 22 can be filled on the machine 1. The tray mobile 22 is partially extracted from the support 34.

Le bac mobile de récupération d'eau de condensas 22 peut être équipé d'un filtre 38 placé au niveau de l'ouverture 31 dudit bac mobile de récupération d'eau de condensas 22. Ledit filtre 38 peut être nettoyé automatiquement lors du vidage du bac mobile de récupération d'eau de condensas 22.The mobile condensate water collection tray 22 may be equipped with a filter 38 placed at the opening 31 of said mobile condensate water collection tray 22. Said filter 38 may be cleaned automatically during the emptying of the mobile condensate water collection tray 22.

Le bac mobile de récupération d'eau de condensas 22 peut être équipé d'au moins une partie transparente sur la paroi en face frontale de la machine 1. De cette manière, l'utilisateur peut visualiser le niveau d'eau de condensas à l'intérieur dudit bac mobile 22.The mobile condensate water collection tray 22 can be equipped with at least one transparent part on the front face wall of the machine 1. In this way, the user can visualize the water level of condensates at the interior of said movable tray 22.

Selon un autre mode de réalisation de l'invention, le bandeau de commande de la machine 1 peut comprendre des moyens d'affichage permettant de visualiser le niveau d'eau de condensas dans le bac mobile de récupération d'eau de condensas 22.According to another embodiment of the invention, the control panel of the machine 1 may comprise display means making it possible to display the level of condensate water in the mobile condensate water collection tray 22.

Le bac mobile de récupération d'eau de condensas 22 est rempli en eau du réseau pour le premier programme de génération de vapeur de ladite machine 1.The mobile condensate water recovery tray 22 is filled with water from the network for the first steam generation program of said machine 1.

Ainsi, le générateur de vapeur 12 évite les problèmes rencontrés avec une eau pure empêchant la génération de vapeur. L'eau de condensas récupérée lors d'un programme de séchage est mélangée à l'eau du réseau initialement versée dans le bac mobile 22 afin de permettre un bon fonctionnement du générateur de vapeur 12.Thus, the steam generator 12 avoids the problems encountered with pure water preventing the generation of steam. The condensate water recovered during a drying program is mixed with the water of the network initially poured into the mobile tank 22 in order to allow the steam generator 12 to function properly.

La conduite 26 d'alimentation du générateur de vapeur 12 est remplie d'eau de condensas à tout instant d'un programme de génération de vapeur.The supply line 26 of the steam generator 12 is filled with condensate water at any time of a steam generation program.

Ainsi, le générateur de vapeur 12 peut être mis en fonctionnement à tout instant au cours d'un programme sélectionné de la machine à sécher le linge à condensation 1. La pompe d'alimentation 20 du générateur de vapeur 12 ne peut être désamorcée et provoquer du bruit. La pompe d'alimentation 20 du générateur de vapeur 12 peut ainsi alimenter ce dernier en eau de condensas quelque soit le niveau d'eau de condensas dans le bac mobile de récupération d'eau de condensas 22.Thus, the steam generator 12 can be operated at any time during a selected program of the dryer 1. The feed pump 20 of the steam generator 12 can not be defused and cause noise. The feed pump 20 of the steam generator 12 can thus supply the latter with condensate water whatever the level of condensate water in the mobile condensate water collection tray 22.

On va décrire à présente le procédé d'alimentation en eau de condensas d'une machine à sécher le linge comprenant un générateur de vapeur conforme à l'invention.We will now describe the condensate water supply method of a dryer machine comprising a steam generator according to the invention.

Le procédé d'alimentation en eau de condensas comprend au moins les étapes suivantes :

  • une première étape de remplissage en eau de condensas du bac mobile de récupération d'eau de condensas 22 par une pompe de relevage 21 ; et
  • une deuxième étape d'alimentation en eau de condensas du générateur de vapeur 12 par l'eau de condensas accumulée dans le bac mobile de récupération d'eau de condensas 22.
The method of supplying condensate water comprises at least the following steps:
  • a first condensate water filling step of the mobile condensate water collection tray 22 by a lifting pump 21; and
  • a second condensate water supply stage of the steam generator 12 by condensate water accumulated in the mobile condensate water recovery tray 22.

Ainsi, le générateur de vapeur 12 est alimenté en eau de condensas pour générer de la vapeur au moindre coût et en évitant les problèmes d'entartrage dudit générateur de vapeur 12 par l'eau. L'eau de condensas alimentant le générateur de vapeur 12 est distillée et par conséquent contient peu de matière pouvant se déposer sur la surface intérieure dudit générateur de vapeur 12.Thus, the steam generator 12 is supplied with condensate water to generate steam at the lowest cost and avoiding scaling problems of said steam generator 12 with water. The condensate water supplying the steam generator 12 is distilled and therefore contains little material that can be deposited on the inner surface of said steam generator 12.

Ce procédé permet de recycler l'eau de condensas pour la génération de vapeur avant de vider le bac mobile de récupération d'eau de condensas en dehors de la machine à sécher le linge à condensation 1. Des économies d'eau sont ainsi réalisées en utilisant un tel procédé d'alimentation d'un générateur de vapeur et l'utilisation d'eau de condensas permettant de maintenir en bon état de fonctionnement le générateur de vapeur 12 au cours de la durée de vie de la machine à sécher le linge à condensation 1.This process recycles the condensate water for the steam generation before emptying the mobile condensate drain tray outside the dryer 1. The water savings are thus achieved by using such a method of supplying a steam generator and the use of condensate water to maintain the steam generator 12 in good working order during the service life of the dryer. condensation 1.

Selon une caractéristique préférée de l'invention, ledit procédé comprend une troisième étape de génération de vapeur par le générateur de vapeur 12 et l'introduction de la vapeur produite dans le circuit de séchage 4 en amont d'un tambour 2 relié audit circuit de séchage 4.According to a preferred feature of the invention, said method comprises a third step of steam generation by the steam generator 12 and the introduction of the steam produced in the drying circuit 4 upstream of a drum 2 connected to said steam circuit. drying 4.

Ainsi, le défroissage du linge est garanti sans créer une surchauffe des pièces de linge par une injection directe de vapeur dans le tambour 2. Les pièces de linge contenues dans le tambour 2 ne peuvent être brûlées par la vapeur provenant du générateur de vapeur 12.Thus, the unwinding of the laundry is guaranteed without creating an overheating of the laundry items by a direct injection of steam into the drum 2. The laundry items contained in the drum 2 can not be burned by the steam from the steam generator 12.
