De manière générale, l'invention concerne les machines à sécher le linge, et plus particulièrement les machines à usage domestique.In general, the invention relates to machines for drying clothes, and more particularly machines for domestic use.

On connaît d'une part des machines à laver le linge qui proposent une introduction de vapeur dans le tambour lors d'un cycle de lavage.On the one hand, there are known laundry washing machines which propose an introduction of steam into the drum during a washing cycle.

Ce type de machine à laver le linge est décrit par exemple dans le document EP1275767 .This type of washing machine is described for example in the document EP1275767 .

Cependant, ces machines à laver le linge ont l'inconvénient de ne pas disposer d'un moyen de chauffage de l'air. Par conséquent, la vapeur est introduite dans une structure froide et condense immédiatement sur les parois de la structure. Ces machines à laver le linge ne permettent pas de défroisser le linge efficacement et le linge est humidifié par la vapeur condensée sur les parois du tambour.However, these washing machines have the disadvantage of not having a means of heating the air. Therefore, the steam is introduced into a cold structure and immediately condenses on the walls of the structure. These laundry machines do not allow the laundry to be de-wrinkled effectively and the laundry is wetted by condensed steam on the walls of the drum.

La présente invention a pour but de résoudre les inconvénients précités et de proposer une machine à sécher le linge permettant de réduire le froissage du linge.The present invention aims to solve the aforementioned drawbacks and to provide a dryer machine to reduce the creasing of laundry.

A cet effet, la présente invention vise une machine à sécher le linge comprenant une carrosserie, ladite carrosserie étant adaptée à loger un tambour, ledit tambour étant adapté à sécher le linge par une circulation d'air chaud au moyen d'un circuit d'air chaud en boucle fermée, l'air étant chauffé par au moins un élément chauffant et traversant le linge contenu dans le tambour, ladite machine comprenant un condenseur, ledit condenseur étant traversé par l'air chaud et humide provenant dudit tambour au moyen d'un ventilateur, ledit condenseur refroidissant l'air chaud et humide et condensant l'humidité de cet air chaud.For this purpose, the present invention is directed to a machine for drying the laundry comprising a bodywork, said body being adapted to house a drum, said drum being adapted to dry the laundry by a hot air circulation by means of a circuit of hot air in a closed loop, the air being heated by at least one heating element and passing through the laundry contained in the drum, said machine comprising a condenser, said condenser being traversed by the hot and humid air coming from said drum by means of a fan, said condenser cooling the hot and humid air and condensing the humidity of this hot air.

Cette machine comprend un générateur de vapeur alimenté en eau, la vapeur produite par ledit générateur de vapeur étant introduite dans ledit circuit d'air chaud de sorte à humidifier le linge contenu dans ledit tambour et en aval dudit condenseur de sorte à limiter la condensation dans ledit condenseur.This machine comprises a steam generator supplied with water, the steam produced by said steam generator being introduced into said hot air circuit so as to moisten the laundry contained in said drum and downstream of said condenser so as to limit condensation in said condenser.

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.

A l'unique dessin annexé, donné à titre d'exemple non limitatif :

  • la figure 1 représente une vue schématique en coupe d'une machine à sécher le linge.
In the only appended drawing, given by way of non-limiting example:
  • the figure 1 is a schematic sectional view of a dryer.

On va décrire tout d'abord en référence à la figure 1 une machine à sécher le linge 1 équipée d'un générateur de vapeur.We will first describe with reference to the figure 1 a dryer 1 equipped with a steam generator.

Cette machine à sécher le linge peut être une machine à sécher le linge à usage domestique ou une lavante-séchante.This dryer may be a household clothes dryer or a washer-dryer.

On a illustré sur ce mode de réalisation une machine à chargement par le dessus. Bien entendu, la présente invention s'applique à tous les types de machine à sécher le linge, et notamment à chargement frontal.In this embodiment, an overhead loading machine has been illustrated. Of course, the present invention applies to all types of machine to dry the linen, and in particular with front loading.

Cette machine à sécher le linge 1 comporte une carrosserie comprenant une ouverture d'accès à l'intérieur de la carrosserie.

Un tableau de commande est également prévu en partie supérieure de la machine 1.A control panel is also provided in the upper part of the machine 1.

Seuls les moyens spécifiques à la mise en oeuvre du procédé de défroissage du linge conforme à l'invention seront décrits ci-après.Only the specific means for the implementation of the method of unwinding the laundry according to the invention will be described below.

Bien entendu, la machine à sécher le linge conforme à l'invention comporte l'ensemble des équipements et moyens nécessaires à la mise en oeuvre d'un processus de séchage classique dans une telle machine à tambour rotatif.Of course, the dryer according to the invention comprises all the equipment and means necessary for the implementation of a conventional drying process in such a rotary drum machine.

La machine à sécher le linge 1 comprend un générateur de vapeur 12 avec une alimentation en eau par goutte à goutte.The laundry dryer 1 comprises a steam generator 12 with a water supply by drip.

En pratique, le générateur de vapeur 12 est un générateur de vapeur à tube avec un débit d'eau faible. Le diamètre du tube du générateur de vapeur 12 est de l'ordre de 8mm.In practice, the steam generator 12 is a tube steam generator with a low water flow rate. The diameter of the tube of the steam generator 12 is of the order of 8 mm.

On va décrire à présent une machine à sécher le linge adapté à mettre en oeuvre le procédé de défroissage du linge conforme à l'invention, en référence à la figure 1.We will now describe a drying machine adapted to implement the method of degreasing the laundry according to the invention, with reference to the figure 1 .

Une machine à sécher le linge 1 à condenseur comprend deux circuits d'air. Un premier circuit d'air est communément appelé circuit d'air chaud 4 et un second circuit d'air appelé circuit d'air froid 5.A condenser dryer 1 comprises two air circuits. A first air circuit is commonly called a hot air circuit 4 and a second circuit of air 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. The heated air passes through the laundry contained in the drum 2 and the heated air is charged with the moisture contained by the laundry. During this phase, the air is cooled from a temperature of about 110 ° C to a temperature of about 70 ° C.

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 1 peut également être pourvue d'un condenseur 9 à plaques à la place d'un condenseur 9 à tubes.The laundry dryer 1 may also be provided with a plate condenser 9 in place 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. Le ventilateur 10 propulse l'air ambiant dans le condenseur 9 sur l'extérieur des tubes dudit condenseur 9 afin de le refroidir. L'air ambiant réchauffé dans le condenseur 9 est évacué dans une pièce par une face frontale de la machine à sécher le linge 1.The cold air circuit 5 is in an open circuit where ambient air is sucked by a fan 10 at the rear of the dryer 1. The fan 10 propels the ambient air into the condenser 9 on the floor. outside the tubes of said condenser 9 in order to cool it. The ambient air heated in the condenser 9 is discharged into a room through a front face of the dryer 1.

Un moteur 11 permet l'entraînement du tambour 2 pour le brassage du linge avec une rotation alternée afin d'éviter le nouage du linge. 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.

L'eau récupérée par le condenseur 9 peut être relevée par une pompe vers un bac placé en partie haute de la machine 1, soit récupérée par gravité dans un bac en partie basse de la machine 1 en fonction de ladite machine à sécher le linge 1.The water recovered by the condenser 9 can be raised by a pump to a tank placed in the upper part of the machine 1, or recovered by gravity in a tray at the bottom of the machine 1 according to said dryer machine 1 .

La machine à sécher le linge 1 est également équipée d'un générateur de vapeur 12 alimenté en eau par une pompe provenant d'un bac. Lors de la mise en oeuvre d'un cycle de défroissage du linge, la vapeur produite par le générateur de vapeur 12 est injectée dans le circuit d'air chaud 4 pour humidifier le linge afin de le défroisser.The dryer 1 is also equipped with a steam generator 12 supplied with water by a pump from a tank. During the implementation of a laundry cycle, the steam produced by the steam generator 12 is injected into the hot air circuit 4 to moisten the laundry in order to straighten it.

Le bac du générateur de vapeur 12 peut être rempli par l'utilisateur avec de l'eau du réseau ou encore de l'eau déminéralisée.The tank of the steam generator 12 can be filled by the user with mains water or demineralised water.

Le cycle de défroissage du linge se déroule avec une rotation du tambour 2 alternée pour éviter le nouage du linge. La rotation du tambour 2 contenant le linge à défroisser permet de brasser le linge et créer un échange entre l'air humide et la vapeur et avec le linge.The laundry cycle unwinds with a rotation of the drum 2 alternating to avoid the knotting of the laundry. The rotation of the drum 2 containing the laundry to be straightened makes it possible to stir the laundry and to create an exchange between the moist air and the steam and with the linen.

On va décrire à présent le procédé de défroissage du linge conforme à l'invention, en référence à la figure 1.We will now describe the method of unwinding the laundry according to the invention, with reference to the figure 1 .

La charge de linge introduite dans le tambour 2 de la machine à sécher le linge 1 est principalement sèche et froissée au départ du cycle de défroissage du linge.The load of laundry introduced into the drum 2 of the dryer 1 is mainly dried and creased at the start of the laundry cycle.

Le procédé de défroissage du linge dans une machine à sécher le linge 1 comprend un générateur de vapeur 12, un condenseur 9 et un tambour 2 logé à l'intérieur d'une carrosserie.The method of straightening the laundry in a dryer 1 comprises a steam generator 12, a condenser 9 and a drum 2 housed inside a body.

Ledit tambour 2 contient le linge à défroisser et est relié audit condenseur 9 par une conduite 13. Ledit condenseur 9 est relié à au moins un ventilateur 8 par une conduite 14. Et ledit au moins un ventilateur 8 est relié audit tambour 2 par une conduite 15.Said drum 2 contains the laundry to be stripped and is connected to said condenser 9 by a pipe 13. Said condenser 9 is connected to at least one fan 8 by a pipe 14. And said at least one fan 8 is connected to said drum 2 by a pipe 15.

Le procédé de défroissage du linge comporte successivement les étapes suivantes :

  • une première phase de préchauffage du générateur de vapeur 12 ;
  • une seconde phase de préchauffage du tambour 2 par au moins un élément chauffant 6 et une circulation d'air chaud générée par ledit au moins un ventilateur 8 ;
  • une troisième phase de génération de vapeur et de circulation de la vapeur du générateur de vapeur 12 au tambour 2 ;
  • une quatrième étape d'évacuation de la vapeur du tambour 2 et de refroidissement du linge contenu dans ledit tambour 2.
The method of degreasing the laundry successively comprises the following steps:
  • a first preheating phase of the steam generator 12;
  • a second preheating phase of the drum 2 by at least one heating element 6 and a hot air flow generated by said at least one fan 8;
  • a third phase of steam generation and steam circulation of the steam generator 12 to the drum 2;
  • a fourth step of evacuating the steam from the drum 2 and cooling the laundry contained in said drum 2.

Le remplissage du bac du générateur de vapeur 12 peut être rempli à tout moment du procédé de défroissage du linge conforme à l'invention. Ce remplissage est possible grâce au générateur de vapeur 12 alimenté en eau en goutte à goutte par une ouverture d'entrée. Le générateur de vapeur 12 peut être un réservoir fermé chauffant au niveau de sa partie inférieure. Le générateur de vapeur 12 comprend une ouverture de sortie pour diriger la vapeur produite vers le circuit d'air chaud 4 de la machine à sécher le linge 1.The filling of the tank of the steam generator 12 can be filled at any time with the method of unwinding the laundry according to the invention. This filling is possible thanks to the steam generator 12 supplied with water drip through an inlet opening. The steam generator 12 may be a closed heating tank at its lower part. The steam generator 12 includes an outlet opening for directing the generated steam to the hot air circuit 4 of the dryer 1.

La première phase du procédé de défroissage du linge consiste à chauffer le générateur de vapeur 12 pour que l'eau introduite dans ce dernier tombe sur une surface chauffée et l'eau est vaporisée instantanément.The first phase of the laundry stripping process involves heating the steam generator 12 so that the water introduced into it falls on a heated surface and the water is vaporized instantly.

Pour permettre l'introduction de la vapeur dans le circuit d'air chaud 4 de la machine à sécher le linge 1, la structure de ladite machine, en particulier le tambour 2, doit être suffisamment chaude pour éviter la condensation de la vapeur sur les parties métalliques et / ou froides ainsi que sur ledit au moins un élément chauffant 6. Ledit au moins un élément chauffant 6 pourrait être dégradé par la présence d'eau. En particulier dans le cas où ledit au moins un élément chauffant 6 est non blindé.To allow the introduction of steam into the hot air circuit 4 of the clothes dryer 1, the structure of said machine, in particular the drum 2, must be sufficiently hot to prevent condensation of the steam on the machine. metal parts and / or cold and on said at least one heating element 6. Said at least one heating element 6 could be degraded by the presence of water. In particular in the case where said at least one heating element 6 is unshielded.

En outre, le fait d'empêcher la condensation de la vapeur supprime la possibilité d'observer des taches d'eau sur le linge.In addition, preventing the condensation of steam eliminates the possibility of observing water spots on the laundry.

Ledit au moins un élément chauffant 6 est utilisé à la moitié de sa puissance lors de la seconde phase de préchauffage du tambour 2.Said at least one heating element 6 is used at half of its power during the second preheating phase of the drum 2.

Préférentiellement, ledit au moins un élément chauffant 6 est utilisé sur une seule partie et notamment celle placée en partie amont dans le circuit de d'air chaud 4. L'utilisation de la partie amont dudit au moins un élément chauffant 6 permet d'éviter la condensation sur la totalité dudit au moins un élément chauffant 6. La partie amont dudit au moins un élément chauffant 6 correspond à la première moitié inférieure dudit au moins un élément chauffant 6 illustré à la figure 1.Preferably, said at least one heating element 6 is used on a single part and in particular that placed in the upstream part in the hot air circuit 4. The use of the upstream part of said at least one heating element 6 makes it possible to avoid condensation of all of said at least one heating element 6. The upstream portion of said at least one heating element 6 corresponds to the first lower half of said at least one heating element 6 illustrated in FIG. figure 1 .

L'utilisation de la demi puissance dudit au moins un élément chauffant 6 permet d'économiser de l'énergie et de limiter la puissance de la machine 1.The use of the half power of said at least one heating element 6 saves energy and limits the power of the machine 1.

En outre, le fonctionnement dudit au moins un élément chauffant à la moitié de sa puissance permet de limiter la température à l'intérieur du tambour pour une meilleure préservation du linge. De cette manière, une surchauffe n'est pas provoquée sur la surface du linge placé à l'intérieur du tambour.In addition, the operation of said at least one heating element to half of its power limits the temperature inside the drum for better preservation of laundry. In this way, overheating is not caused on the surface of the laundry placed inside the drum.

Le tambour 2 est entraîné en rotation pour brasser le linge et homogénéiser l'introduction de vapeur dans ledit tambour 2 lors de la troisième phase de génération de vapeur et de circulation de la vapeur du générateur de vapeur 12 audit tambour 2.The drum 2 is rotated to stir the laundry and homogenize the introduction of steam into said drum 2 during the third steam generation and steam circulation phase of the steam generator 12 to said drum 2.

Le circuit d'air chaud 4 permet de minimiser la condensation de vapeur pour optimiser la consommation d'eau et l'apport d'énergie thermique.The hot air circuit 4 makes it possible to minimize steam condensation in order to optimize the consumption of water and the supply of thermal energy.

Le circuit d'air chaud 4 permet de condenser le moins possible de vapeur, provenant du tambour 2, afin de consommer une quantité minimale d'eau et de limiter l'apport d'énergie thermique, et de réduire le bruit de la machine à sécher le linge 1 de l'ordre de 2dB.The hot air circuit 4 makes it possible to condense as little steam as possible, coming from the drum 2, in order to consume a minimum quantity of water and to limit the supply of thermal energy, and to reduce the noise of the machine to drying the laundry 1 of the order of 2dB.

Le moyen utilisé pour diminuer le rendement du condenseur 9 est de réduire le flux d'air ambiant pour limiter l'échange thermique.The means used to reduce the efficiency of the condenser 9 is to reduce the flow of ambient air to limit the heat exchange.

Lors de la troisième phase de génération de vapeur et de circulation de la vapeur du générateur de vapeur 12 au tambour 2, une rotation inversée d'un ventilateur 10 du circuit d'air froid 5 est mise en oeuvre. La rotation du ventilateur 10 du circuit d'air froid 5 est inversée par rapport au sens de fonctionnement optimum dudit ventilateur 10. Ainsi, la condensation de la vapeur est minimisée dans le but d'optimiser le défroissage du linge.During the third steam generation and steam circulation phase of the steam generator 12 to the drum 2, an inverted rotation of a fan 10 of the cold air circuit 5 is carried out. The rotation of the fan 10 of the cold air circuit 5 is reversed relative to the optimum operating direction of said fan 10. Thus, the condensation of the steam is minimized in order to optimize the unwinding of the laundry.

La rotation en sens inverse dudit ventilateur 10 du circuit d'air froid 5, le débit d'air est limité et par conséquent le rendement du condenseur 9 est réduit. Le condenseur 9 est moins refroidi donc la vapeur présente dans le circuit d'air chaud 4 est moins condensée. Ladite vapeur peut alors être réinjectée dans le tambour 2 de la machine à sécher le linge 1.The rotation in the opposite direction of said fan 10 of the cold air circuit 5, the air flow is limited and therefore the efficiency of the condenser 9 is reduced. The condenser 9 is cooled less so the steam present in the hot air circuit 4 is less condensed. Said steam can then be reinjected into the drum 2 of the dryer 1.

Ainsi, un gain d'énergie et de consommation d'eau est réalisé.Thus, a gain in energy and water consumption is achieved.

Dans le cas où un seul moteur 11 entraîne le tambour 2 et ledit ventilateur 10 du circuit d'air froid 5, la rotation du tambour 2 est également inversée lors de ladite troisième phase.In the case where a single motor 11 drives the drum 2 and said fan 10 of the cold air circuit 5, the rotation of the drum 2 is also reversed during said third phase.

L'utilisation d'un même moteur 11 pour entraîner le ventilateur 10 du circuit d'air froid 5 et le tambour 2 permet de réaliser un gain de coût et de place dans la machine 1.The use of the same motor 11 for driving the fan 10 of the cold air circuit 5 and the drum 2 makes it possible to save money and space in the machine 1.

Le rendement du condenseur 9 avec un ventilateur 10 du circuit d'air froid 5 tournant dans le sens positif est de l'ordre de 70%.The efficiency of the condenser 9 with a fan 10 of the cold air circuit 5 rotating in the positive direction is of the order of 70%.

La puissance échangée dans le condenseur 9 est de l'ordre de 2000W.The power exchanged in the condenser 9 is of the order of 2000W.

Le changement de sens de rotation du tambour 2 permet également de modifier le sens de rotation du ventilateur 10 et ainsi de modifier le débit d'air ambiant traversant le condenseur 9. Un débit d'air plus faible généré par le ventilateur 10 crée un échange thermique moindre entre l'air chaud humide et l'air ambiant. Ainsi, le rendement du condenseur 9 est de l'ordre de 30%.The change of direction of rotation of the drum 2 also makes it possible to modify the direction of rotation of the fan 10 and thus to modify the flow of ambient air passing through the condenser 9. A lower air flow generated by the fan 10 creates an exchange less heat between moist warm air and ambient air. Thus, the efficiency of the condenser 9 is of the order of 30%.

La puissance échangée dans le condenseur 9 est de l'ordre de 800W.The power exchanged in the condenser 9 is of the order of 800W.

En outre, le ventilateur 8 du circuit d'air chaud 4 est aussi entraîné par le moteur 11 et ledit ventilateur 8 tournant également en sens inverse. Ainsi, le circuit d'air chaud 4 a un débit d'air moindre. Par ailleurs, la puissance dudit au moins un élément chauffant 6 est plus faible pour obtenir une température en sortie de la conduite 15 sensiblement identique.In addition, the fan 8 of the hot air circuit 4 is also driven by the motor 11 and said fan 8 also rotating in the opposite direction. Thus, the hot air circuit 4 has a lower air flow. Moreover, the power of said at least one heating element 6 is lower to obtain a temperature at the outlet of the pipe 15 substantially identical.

Un débit d'air chaud plus faible permet également de limiter le risque d'entraînement de gouttelettes d'eau pouvant être évacuées avec la vapeur dans le circuit d'air chaud 4 et par conséquent de limiter le risque de court-circuit dudit au moins un élément chauffant 6.A lower hot air flow rate also makes it possible to limit the risk of entrainment of water droplets that can be discharged with the steam in the hot air circuit 4 and consequently to limit the risk of short circuiting of said at least one a heating element 6.

La génération de vapeur peut être interrompue lors de la rotation du tambour 2 dans ledit sens positif.The steam generation can be interrupted during the rotation of the drum 2 in said positive direction.

Le refroidissement par le condenseur 9 est également moins important, d'où, un échange thermique minimisé.The cooling by the condenser 9 is also less important, hence a minimized heat exchange.

La vapeur est introduite et mise en circulation dans un circuit d'air chaud 4 de la machine à sécher le linge 1 lors de la troisième phase de génération de vapeur et de circulation de la vapeur du générateur de vapeur 12 au tambour 2.The steam is introduced and put into circulation in a hot air circuit 4 of the dryer 1 during the third steam generation and steam circulation phase of the steam generator 12 to the drum 2.

L'introduction de vapeur est régulée par des temps de marche et d'arrêt du générateur de vapeur 12.The introduction of steam is regulated by the on and off times of the steam generator 12.

Le temps d'arrêt du générateur de vapeur 12 est présent pour stabiliser la température dudit générateur de vapeur 12 en le refroidissant par de l'eau entrant en goutte à goutte dans ce dernier.The stopping time of the steam generator 12 is present to stabilize the temperature of said steam generator 12 by cooling it with water drip into it.

L'eau introduite en goutte à goutte est à température ambiante et refroidit le générateur de vapeur étant chaud. Lors des temps d'arrêt d'introduction d'eau dans le générateur de vapeur, ce dernier se réchauffe. Les temps d'arrêt d'introduction d'eau sont nécessaires pour provoquer la montée en température du générateur de vapeur. Si ces temps d'arrêt d'introduction d'eau ne sont pas prévus, le générateur de vapeur évacue des gouttelettes d'eau dans le circuit d'air chaud.The water introduced drop by drop is at room temperature and cools the steam generator being hot. During water supply stopping times in the steam generator, the latter heats up. Stopping water introduction times are necessary to cause the temperature rise of the steam generator. If these water supply stoppages are not provided, the steam generator discharges water droplets into the hot air circuit.

Ainsi, l'eau n'est pas introduite sous forme liquide dans le circuit d'air chaud 4 de la machine à sécher le linge 1 mais uniquement sous forme vapeur.Thus, the water is not introduced in liquid form into the hot air circuit 4 of the dryer 1 but only in vapor form.

Le condenseur 9 fonctionne à son rendement maximal lors de la quatrième phase d'évacuation de la vapeur du tambour 2 et de refroidissement du linge contenu dans ledit tambour 2.The condenser 9 operates at its maximum efficiency during the fourth phase of evacuation of the steam from the drum 2 and cooling the laundry contained in said drum 2.

Lors de cette quatrième phase du procédé de défroissage du linge, les ventilateurs 8 et 10 fonctionnent dans le sens positif.During this fourth phase of the laundry degreasing process, the fans 8 and 10 operate in the positive direction.

Cette quatrième phase du procédé de défroissage du linge permet de retirer le linge du tambour 2 de la machine à sécher le linge 1 sans l'évacuation d'un nuage de vapeur à l'ouverture de la porte d'accès de ladite machine 1. En outre, la quatrième phase du procédé permet d'éviter à l'utilisateur de se brûler les mains en retirant le linge du tambour 2.This fourth phase of the laundry degreasing process makes it possible to remove the laundry from the drum 2 of the dryer 1 without the evacuation of a cloud of steam when the access door of said machine 1 is opened. In addition, the fourth phase of the method avoids the user to burn his hands by removing the laundry drum 2.

La première phase du procédé de défroissage du linge a une durée de l'ordre de 2 minutes à 3 minutes. La durée de la première phase du procédé de défroissage du linge est dépendante du type de générateur de vapeur et de sa puissance.The first phase of the laundry degreasing process has a duration of the order of 2 minutes to 3 minutes. The duration of the first phase of the laundry degreasing process is dependent on the type of steam generator and its power.

La seconde phase de préchauffage du tambour 2 par au moins un élément chauffant 6 et une circulation d'air chaud générée par ledit au moins un ventilateur 8 a une durée de l'ordre de 3 minutes.The second phase of preheating the drum 2 with at least one heating element 6 and a circulation of hot air generated by said at least one fan 8 has a duration of the order of 3 minutes.

La première phase et la seconde phase peuvent être réalisées simultanément. Dans ce mode de réalisation de l'invention, la deuxième phase du procédé de défroissage du linge se prolonge d'environ une minute par rapport à ladite première phase.The first phase and the second phase can be performed simultaneously. In this embodiment of the invention, the second phase of the laundry degreasing process is approximately one minute longer than said first phase.

La troisième phase de génération de vapeur et de circulation de la vapeur du générateur de vapeur 12 au tambour 2 a une durée de l'ordre de 10 minutes.The third phase of steam generation and steam circulation of the steam generator 12 to the drum 2 has a duration of the order of 10 minutes.

La quatrième phase d'évacuation de la vapeur du tambour 2 et de refroidissement du linge contenu dans ledit tambour 2 a une durée de l'ordre de deux minutes.The fourth phase of evacuating the steam from the drum 2 and cooling the laundry contained in said drum 2 has a duration of the order of two minutes.

La quantité d'eau injectée à chaque cycle de défroissage du linge dans le générateur de vapeur 12 est de l'ordre de 200mL à 300mL.The amount of water injected at each cycle of stripping the laundry in the steam generator 12 is of the order of 200mL to 300mL.

The method of straightening the laundry in a condensing dryer 1 comprises at least the following step:

  • said brewing phase of the laundry being performed during a steam introduction phase in a hot air circuit 4 of said machine 1.

Cette phase de brassage du linge permet de limiter le refroidissement du condenseur 9 et par conséquent la condensation de la vapeur.This brewing phase of the laundry makes it possible to limit the cooling of the condenser 9 and consequently the condensation of the steam.

Ainsi, la consommation en eau et en énergie est optimisée lors de la mise en oeuvre d'un cycle de défroissage du linge par de la vapeur. La durée du cycle de défroissage est également optimisée.Thus, the consumption of water and energy is optimized during the implementation of a laundry cycle by steam steaming. The duration of the anti-crease cycle is also optimized.
