The method involves scraping fluff on a fluff filter (2) using a scraping unit (17) when a fan is operated in inversed rotation direction that is inversed with respect to a operational rotation direction during a drying cycle of clothes, where the scraping unit is placed in the filter that is placed in a drying air circuit (5) of a clothes drying machine (1). A drum (6) is crossed by drying air from the drying air circuit, and the scraping unit is moved with respect to the filter.

Description

The present invention relates to a method for removing lint from laundry from a clothes drying machine equipped with a lint filter. It relates generally to the field of clothes drying machines or washer-dryers in which the laundry is placed in a rotary drum traversed by a hot air flow for extracting moisture from the laundry and the fluff formed on the laundry. A hot air circulation circuit, open or closed, allows to introduce drying air into the drum and to evacuate this air after passing through the laundry. Known drying machines have a filter disposed in the drying air circuit to stop the fluff. This filter clogs up quickly and prevents normal circulation of drying air. These drying machines have the disadvantage of requiring frequent cleaning of the filter by the user to maintain the efficiency of drying and a good performance of these devices. A tumble dryer described in EP 0 722 519 A1 is also known.

This tumble dryer features an annular lint filter that surrounds the tumble dryer drum and surrounds the tumble dryer door. The heated air enters through an inlet at one end of the drum, passes through the laundry in the drum (taking the lint from the laundry as it passes), passes through the annular lint filter, and exits the dryer. During the operation of the dryer, the lint is deposited on the inner surface of the rotary filter and eventually accumulates to form a felted layer. A razor blade attached to the tumble dryer body and aligned with the filter surface (at a fixed distance therefrom) detaches the felted layer of lint from the filter when the thickness of the felted lint layer is such that the razor blade comes in contact with it. This felted layer of fluff thus removed from the filter surface is then collected in a cavity located in the door of the dryer to be stored and then discarded. However, this dryer has the disadvantage of modifying the structure of a traditional tumble dryer significantly. This machine dryer requires a rotational movement between the drum and a razor blade to drive the wad to an extractable reservoir. Such a device for removing lint from a filter is complex to implement and generates costly production costs. Furthermore, this dryer has the disadvantage of partially loosening the lint of linen collected on the annular lint filter and cause the passage of lint of fine linen through said lint filter.

Cloth lint is peeled off by the force applied by the razor blade on the lint filter with low efficiency since the lint of laundry is sucked by the air flow passing through the lint filter and pressed against it.  The detachment of the lint of laundry when the fan of the drying circuit is put into operation causes the passage of lint of laundry through said fluff filter and fouling of said drying circuit.  The present invention aims to solve the aforementioned drawbacks and generally to reduce the stress associated with the elimination of the flock of linen amassed on the filter.  Furthermore, the dryer machine reduces the frequency of withdrawal of the laundry pack by the user outside the dryer machine.  For this purpose, the present invention is directed to a method of removing lint from laundry of a laundry drying machine comprising a drum, said drum being traversed by drying air from a drying air circuit, said dryer air circuit comprising at least one fan, and said machine comprising at least one fluff filter placed in said drying air circuit, said at least one fluff filter comprising at least one fluff scraper means, said at least one scraping means moving relative to said at least one fluff filter, said at least one scraping means scraping the fluff on said at least one fluff filter, said fluff accumulating in a storage area.  According to the invention, said method comprises at least one step of scraping said at least one fluff filter during at least one reversal of the direction of rotation of said at least one fan implemented during a laundry drying cycle. .  Thus, the scraping of the lint filter by the scraping means is implemented when the air flow of at least one fan of the drying air circuit is reduced.  Therefore, the lint of laundry is less strongly sucked by the fan of the drying air circuit and the effort to exert to take off the lint-laden fluff against at least one filter wall of the lint filter is minimized.  In this way, the lint of linen is easily peeled off from at least one filter wall of the lint filter to be discharged into a lint storage area in the dryer.  The drying machine thus makes it possible to scrape the lint of linen gathered on a filter and to move these lint loads to store them inside a storage area of said machline.  These lint of laundry are thus stored for several drying cycles before being removed by the user outside the dryer in a garbage can.  In addition, the traditional collection of lint with the fingers of the user against the lint filter is replaced by the friction of the scraping means moving along the lint filter, thus facilitating the operation.  The scraping means makes it possible to reduce the stress associated with the removal of the lint from the lint filter by allowing said fluff filter to be cleaned at each drying cycle of the laundry or at a cleaning frequency. determined.  The lint of laundry is thus stored in a storage area inside the dryer for several drying cycles of the laundry prior to disposal by the user in a bin.  The scraping means makes it easier to clean the fluff filter.  Furthermore, the dryer is adapted to receive fluff filters of various shapes and dimensions cooperating with scraping means.  Preferably, the lint storage area is provided outside and below the lint filter, allowing drying air to pass through said filter during a laundry drying cycle to ensure circulation. drying air normal in the drying air circuit and amassing new lint of laundry on said fluff filter.  The fluff filter comprising scraping means according to the invention makes it possible to guarantee the drying of the laundry articles by an optimal circulation of the drying air in the drying air circuit.  The fluff filter allows a passage of drying air without creating a loss of loads related to lint amassed on it and then collected in a storage area.  The crawling clothes lint by the scraping means falls by gravity into the storage area.  According to a preferred feature of the invention, the step of scraping said at least one fluff filter is carried out when said at least one fan operates in the direction of rotation opposite to the direction of rotation of operation having a flow rate of maximum air.  Thus, the scraping of the lint of laundry on at least one filter wall of the lint filter is facilitated by the decrease of the pressure exerted by the air circulation implemented by at least one fan of the drying air circuit.  The lint of cloth is pressed onto at least one filter wall of the lint filter while allowing effective cleaning of the scraper means moving along the surface of said at least one filter wall.  Practically, the drum and said at least one fan are jointly driven in rotation.  Advantageously, said at least one step of scraping said at least one fluff filter is implemented during several inversions of the direction of rotation of said at least one fan of a laundry drying cycle, and preferably between 2 and 4 inversions. the direction of rotation of the at least one fan of a laundry drying cycle.  Thus, said at least one filter wall of the lint filter is scraped several times by the scraping means during a drying cycle of the laundry carried out by the dryer machine.  In this way, said at least one filter wall of the lint filter is cleaned regularly and the air circulation in the drying air circuit is optimally ensured throughout a drying cycle carried out by the dryer.  According to another preferred feature of the invention, said at least one scraping means is motorized allowing the passage of a scraping position A of at least one filtering wall of said at least one fluff filter at a closed position B at least one inlet opening of the scraped lint storage area and vice versa.  Thus, the lint of laundry collected on the lint filter is scraped by an automated scraping means and collected in a storage area.  In this way, the lint of laundry is scraped on at least one filter wall of the lint filter, said lint falls by gravity into the storage area and in addition it is compressed by the scraping means.  The displacement of the scraping means makes it possible to exert a force on the lint of linen collected in the storage area, thus causing an increase in the density of the cluster of said lint stored in the storage area.  As a result, the amount of lint of laundry stored in the storage area is greater.  In addition, the lint of laundry stored in the storage area is close to the hot and humid airflow flowing through the lint filter.  The proximity of the lint of laundry with the hot and humid air flow through the fluff filter 25 causes the moisture of the airflow to be trapped by the fluff.  The moisture absorbed by the fluff helps to settle the fluff in the storage area.  The compacting of the lint of laundry is in particular due to the increase in weight of said stuffed animals and the fact that these fluff stick together as a result of the absorption of moisture from the air flow passing through the lint filter.  The linted wipes and stored in the storage area may also be compacted by scraping means in said storage area when the amount of lint collected in said storage area is greater than a specified height in said storage area.  The dryer machine equipped with an automated scraping means of a lint filter thus makes it possible to clean said fluff filter as soon as necessary, and particularly between two cycles of drying of the laundry implemented by said machine.  The user thus has no action to perform until the storage area of the scraped laundry fluff is not filled.  In addition, the drying performance of the laundry is identical from the beginning to the end of a drying cycle of the laundry employed by the dryer machine since the lint filter is either cleaned periodically or as soon as the fouling 5 of the latter is detected by control means of said machine.  As a result, the dryer is no longer safe because the user does not clean the dirty lint filter.  Other features and advantages of the invention will become apparent in the description below.  In the accompanying drawings, given by way of non-limiting examples: FIG. 1 schematically and in perspective shows a laundry machine comprising a fluff filter according to the invention; Figure 2 is a perspective view of a lint filter according to the invention; FIGS. 3A, 3B, 3C and 3D are schematic views illustrating the operation of a scraping means between a closed position of an opening of a lint tank and a scraping position of a filter. fluff according to the invention; FIGS. 4A, 4B and 4C are schematic views illustrating the positioning of scraping means in a fluff filter comprising two filter walls according to one embodiment of the invention; and FIGS. 5A, 5B and 5C are schematic views illustrating the positioning of scraping means in a fluff filter comprising a filter wall according to one embodiment of the invention.  We will first describe with reference to Figure 1 a machine dryer 1 equipped with a lint filter 2.  This dryer may be a household clothes dryer or a washer-dryer.  Of course, the present invention applies to all types of machine for drying clothes, including front loading and loading from above the laundry.  This dryer 1 comprises a body 3 comprising an access opening 4 inside the bodywork 3.  An access door (not shown) is adapted to close this opening 4 of the bodywork 3 of the machine 1, in particular: during operation thereof.  In this embodiment, and in no way limiting, the access door is pivotally mounted about an axis of rotation integral with the bodywork 3 of the machine 1.  The bodywork 3 of the machine 1 is adapted to house a drum 6 which is particularly suitable for drying the laundry by a hot air circulation.  The drum 6 is rotatable about an axis during the different phases of the drying cycles of the machine.  Note that Figure 1 is schematic and that many organs necessary for the operation of the machine have been omitted and do not need to be described in detail here.  In order to allow the introduction and removal of laundry within the rotary drum 6, it comprises in a known manner a door.  A control panel is also provided in the upper part of the machine 1.  Of course, the dryer according to the invention comprises all the equipment and means necessary for carrying out a conventional drying process in such a rotating drum machine.  The dryer 1 comprises a drying air circuit 5.  The drying air circuit 5 comprises at least one drying air inlet duct (not shown) and a drying air outlet duct 7.  The air inlet duct is connected to an air inlet of the drum 6 and the air outlet duct 7 to an air outlet 8 of the drum 6.  The drum 6 of the dryer 1 is an integral part of the drying air circuit 5.  The clothes dryer 1 also comprises at least one fan 9 for driving a drying air flow F to pass into the air inlet of the drum 6, to pass through said drum 6 containing the pieces of laundry and to exit through the air outlet 8 of said drum 6.  The drying of the laundry contained in the drum 6 is dried by the flow of air F passing through said drum 6 while said drum 6 is rotated to stir and lift the laundry.  The fan 9 is mounted in the drying air circuit 5 to suck air and force it to flow through the air inlet and air outlet lines 7 of said dryer air circuit. 5.  A heating element (not shown) is mounted in the air inlet duct for heating the drying air to a predetermined temperature controllable by control means (not shown) of the laundry dryer 1 .  The drying air is introduced into the drum 6 through at least one air inlet opening in the drum 6.  The drum 6 contains the clothes to be dried and rotates them during a drying cycle.  The drying cycle allows moisture to be removed from the laundry items by drying moisture-loading air.  The moisture-laden drying air is discharged through at least one outlet opening 8 of the drum 6 and then through the air outlet duct 7.  In one embodiment of the invention, the laundry dryer 1 comprises at least one fluff filter 2 located downstream of the at least one drying air outlet opening 8 of the drum 6.  In a top-loading laundry dryer (not shown), the lint filter can be placed inside the body and preferably below the drum so that the user can remove it and the clean using an access hatch.  Said at least one drying air outlet opening is formed on a flange of the drum connected to the fluff filter via at least one air circulation duct.  In a front load laundry dryer illustrated in FIG. 1, the lint filter 2 may be located below the drum access door 6.  Said at least one drying air outlet opening 8 is made through the drum access door 6.  In this way, at least one filter wall 19 of the fluff filter 2 can be accessible to the user when opening the access door of the drum 6 to be removed and cleaned.  In the case of condensing laundry machines 1, these comprise two air circuits.  A first air circuit is commonly called a hot air circuit and a second air circuit called a cold air circuit.  The hot air circuit is in a closed loop and the air is heated by at least one heating element.  The heated air passes through the laundry contained in the drum 6 and the heated air takes care of the moisture contained in the laundry.  During this phase, the air is cooled from a temperature of the order of 110 ° C. to a temperature of the order of 70 ° C.  The heated and moist air passes through a filter placed at a discharge outlet of the drum 6 to recover lint contained in said heated and moist air.  A fan circulates warm, moist air inside a condenser.  Hot, humid air is cooled in condenser tubes and the moisture in the air is condensed.  The condenser is cooled by heat exchange with ambient air.  Then, the air is again heated by the at least one heating element.  The dryer 1 can also be provided with a plate condenser instead of a tube condenser.  The cold air circuit is in an open circuit where ambient air is sucked by a fan at the back of the dryer 1.  The fan propels the ambient air in the condenser on the outside of the tubes of said condenser to cool it.  The ambient air heated in the condenser is discharged into a room through a front face of the dryer 1.  According to the invention, the lint filter 2 is placed in a housing 10 formed in the drying air circuit 5.  This housing 10 allows easy access by the user to remove said lint filter 2.  Said at least one lint filter: 2 comprises at least one scraping means 17 for lint.  Said at least one scraper means 17 is movable relative to said at least one lint filter 2.  The scraper means 17 can be moved relative to the lint filter 2 to remove lint from it.  The displacement of the doctoring means 17 with respect to the lint filter 2 can be performed automatically.  Said at least one scraper means 17 moves relative to said at least one lint filter 2 held in position in said machine 1.  Preferably, said at least one fluff filter 2 is held in position in the drying air circuit 5.  Said at least one scraper means 17 scrapes the lint on said at least one lint filter 2 and scraped lint accumulates in a storage area 18.  Said at least one scraping means 17 closes at least one inlet opening 11 of the scraped lint storage area 18 at least when said at least one fan 9 of the drying air circuit 5 is put into operation.  Thus, the clothes drying machine 1 makes it possible to scrape the lint of linen gathered on a filter wall 19 of the lint filter 2 and to move these lint loads to store them inside a storage area 18 of said machine 1.  These lint of laundry are thus stored for several drying cycles before being removed by the user outside the dryer 1 in a garbage can.  The storage zone 18 is thus closed during a cycle of operation of the dryer 1, and in particular when a fan 9 of the drying air circuit 5 is started.  The closure of at least one inlet opening 11 of the scraped lint of the storage area 18 thus makes it possible to prevent the lint collected in said storage zone 18 from rising to the level of the lint filter 2 by the suction of a fan 9 of the drying air circuit 5 and that the lint filter 2 and the drying air circuit 5 are fouled by fluff.  The positioning of the scraping means 17 for closing at least one inlet opening 11 of the scraped lint of the storage zone 18 is preferably implemented before the start of the start-up of a fan 9 of the drying air circuit 5.  In addition, the traditional collection of fluff with the fingers of the user against the fluff filter 2 is replaced by the friction of the scraper means 17 moving along the fluff filter 2, thus facilitating the operation .  The scraping means 17 makes it possible to reduce the stress associated with the elimination of the lint of linen gathered on the fluff filter 2 by allowing said fluff filter 2 to be cleaned at each drying cycle of the laundry or at a cleaning frequency. determined.  The lint of laundry is thus stored in a storage area 18 inside the dryer 1 for several drying cycles of the laundry before disposal by the user in a bin.  The scraping means 17 makes it easier to clean the fluff filter 2.  Furthermore, the dryer 1 is adapted to receive lint filters 2 of various shapes and sizes cooperating with scraping means 17.  Preferably, the lint storage zone 18 is arranged outside the lint filter 2 and below it to allow the drying air to pass through said filter 2 during a drying cycle of the laundry to guarantee a normal drying air circulation in the drying air circuit 5 and collecting new lint of laundry on said lint filter 2.  The storage zone 18 is arranged outside the drying air circuit 5 so that the lint of laundry is not entrained by the air flow passing through the lint filter 2 and the scraped lint is not again plated against at least one filter wall 19.  In this way, said at least one filter wall 19 of the lint filter 2 can not be obstructed by linted and stuffed laundry fluff in the storage area 18.  The fluff filter 2 comprising scraping means 17, according to the invention, makes it possible to guarantee the drying of the laundry articles by optimum circulation of the drying air in the drying air circuit 5.  The fluff filter 2 allows a passage of the drying air without creating a loss of loads associated with lint amassed thereon and then collected in a storage area 18.  The lint of laundry scraped by the scraping means 17 falls by gravity into the storage area 18.  The lint of laundry is scraped on at least one filter wall 19 of the lint filter 2, said lint falls by gravity into the storage area 18 and in addition these are compressed by the scraping means 17.  The displacement of the scraping means 17 makes it possible to exert a force on the lint of linen collected in the storage area 18 thus causing an increase in the density of the cluster of said stuffed animals stored in the storage area 18.  As a result, the amount of lint of laundry stored in the storage area 18 is greater.  In addition, the lint of laundry stored in the storage zone 18 are in the vicinity of the hot and humid air flow circulating in the lint filter 2.  The proximity of the lint of laundry with the flow of hot and humid air through the fluff filter 25 causes the moisture of the airflow to be trapped by the fluff.  The moisture absorbed by the lint of laundry promotes the settlement of the lint in the storage area 18.  The compacting of the lint of laundry is in particular due to the increase in weight of said stuffed animals and the fact that these fluff stick together as a result of the absorption of moisture from the air flow passing through the lint filter 2.  Said at least one scraping means 17 scrapes the fluff on at least one filter wall 19 of said at least one fluff filter 2 when driving said at least one scraper means 17 in a single direction P.  Thus, the clothes drying machine 1 makes it possible to scrape the lint of linen gathered on a filter 2 and to move these lint loads to collect them in a predetermined zone.  The scraping means 17 of the lint filter 2 thus make it possible to scrape the lint gathered on at least one filtering wall 19 in a single direction P and thus avoiding the formation of lint balls at any point of said lint filter 2.  The scraping of the lint of laundry in a single direction P allows said lint to be grouped together in a single predetermined area.  The lint of laundry can thus be entrained in the drying air circuit 5 following the actuation of the scraping means 17.  The lint of laundry does not return to the lint filter 2 by the suction generated by the at least one fan 9 of the drying air circuit 5 and the air vortex created in this zone.  In addition, traditional lint collection with the user's fingers against the lint filter is replaced by the friction of the scraper means 17 moving along the lint filter 2, thus facilitating the operation.  The scraping means 17 makes it possible to reduce the stress associated with the elimination of the lint of linen collected on the fluff filter 2 by allowing said fluff filter 2 to be cleaned at each drying cycle of the laundry or at a cleaning frequency. determined.  The lint of laundry can thus be stored in a storage area 18 inside the dryer 1 for several drying cycles of the laundry before disposal by the user in a bin.  The scraper means 17 facilitates the cleaning of the lint filter 2.  Furthermore, the dryer 1 is adapted to receive fluff filters 2 of various shapes and sizes cooperating with scraping means 17.  Preferably, the lint storage zone 18 is arranged outside the fluff filter 2 and below it to allow the drying air to pass through said filter 2 during a drying cycle of the fluff filter 2. in order to ensure a normal drying air circulation in the drying air circuit 5 and to collect new lint of linen on said lint filter 2.  The fluff filter 2 comprising scraping means 17, according to the invention, makes it possible to guarantee the drying of the laundry articles by an optimal circulation of the drying air in the drying air circuit 5.  The fluff filter 2 allows a passage of the drying air without creating a loss of loads associated with lint amassed thereon and then collected in a storage area.  18.  The lint of laundry scraped by the scraping means 17 falls by gravity into the storage area 18.  Said at least one scraping means 17 is set in motion relative to at least one filter wall 19 of said at least one fluff filter 2 between at least two positions A and B.  Said at least one scraping means 17 scrapes the lint gathered on said at least one filter wall 19 of said at least one fluff filter 2 during the movement of said at least one scraper means 17 from said position A to said position B.  Said at least one scraping means 17 slides on said at least one filter wall 19 of said at least one fluff filter 2 without scraping the lint gathered on said at least one filter wall 19 during the displacement of said at least one scraping means 17 from said position B to said position A.  Thus, the lint of garbage collected on the fluff filter 2 can be driven by the scraping means 17 only in one direction P and while allowing a scraper means 17 to move in at least two opposite directions.  The scraping means 17 thus makes round trips on at least one filter wall 19 of the lint filter 2 by detaching the fluff from said at least one filter wall 19 only in a single direction of movement P.  The scraper means 17 thus makes it possible to scrape the lint of linen gathered on at least one filter wall 19 of the lint filter 2 and to return to the initial position without dispersing lint at any point of said lint filter 2.  The scraping means 17 can thus make successive round trips while driving the lint of laundry in only one direction P and more particularly in a storage zone 18 located at a specific location of the dryer 1.  Said at least one scraping means 17 scrapes lint gathered on at least one filter wall 19 of said at least one lint filter 2 when said at least one scraping means 17 is pushed.  And said at least one scraping means 17 slides on at least one filter wall 19 of said at least one fluff filter 2 without scraping the lint accumulated on said at least one filter wall 19 when said at least one scraping means 17 is drawn. .  Thus, the scraper means 17 makes it possible to detach the lint of linen collected on at least one filter wall 19 of the lint filter 2 when the latter is pushed and to slide on at least one filter wall 19 of the lint filter 2 when the one it is pulled.  Scraping of the lint is ensured by applying a force to at least one filter wall 19 when the scraping means 17 is pushed.  The displacement of the scraper means 17 in this direction allows a friction of said scraping means 17 on at least one filter wall 19 and consequently the fluff is detached from said at least one filter wall 19.  Moving the scraper means 17 in an opposite direction allows said scraper means 17 to slide on at least one filter wall 19 and therefore the fluff is not driven by said scraping means 17.  Said at least one scraping means 17 is movable allowing the passage of a scraping position A of said at least one fluff filter 2 to a closure position B of at least one inlet opening 11 of the storage area 18 scraped stuffed animals and vice versa.  Thus, the lint of laundry collected on the lint filter 2 is scraped by an automated scraping means 17 and collected in a storage area 18.  The clothes dryer 1 equipped with an automated scraper means 17 for a lint filter 2 thus enables said fluff filter 2 to be cleaned as necessary, and particularly between two laundry drying cycles carried out by the machine. said machine 1.  The user thus has no action to perform until the storage area 18 scraped lint is not filled.  In addition, the drying performance of the laundry is identical from the beginning to the end of a laundry drying cycle carried out by the laundry dryer 1 since the lint filter is either cleaned periodically or as soon as the fouling of the latter is detected by control means of said machine 1.  The drying machine 1 is thus no longer safe because of non-cleaning by the user of a lint 2 dirty filter.  Said at least one scraping means 17 is driven by a motor 14.  Thus, the lint filter 2 is automatically cleaned by the scraping means 17 scraping the lint gathered on the filter walls 19 of said lint filter 2 and 2931489 -13- amassing scraped lint in the storage area 18.  In this way, the lint filter 2 is cleaned at each drying cycle of the laundry by the automated drive of the scraping means 17.  Said at least one scraping means 17 comprises at least one cutting edge 16 in contact with said at least one.  filtering wall 19 of said at least one lint filter 2.  Said at least one cutting edge 16 of the scraper means 17 makes it possible to detach the lint gathered on said at least one filter wall 19 of the lint filter 2.  The scraper means 17 comprises a cutting edge 16 parallel to at least one filter wall 19 of the lint filter 2.  In the case where the lint filter 2 comprises several filtering walls 19, the scraping means 17 may comprise as many parallel cutting edges 16 as filtering walls 19.  In this way, the doctoring means 17 makes it possible to scrape the surface of the at least one filtering wall 19 uniformly.  Said at least one fluff filter 2 comprises at least one filtering vertical wall 19 scraped by said at least one scraper means 17 in a rotational movement.  Thus, the doctoring means 17 s moves vertically with respect to said at least one filter wall 19.  The scraping means 17 extends at least over the width of said at least one filtering wall 19 in order to scrape all the lint collected on said at least one filtering wall 19.  The edge or ridges of the doctoring means 17 are parallel to one or more filter walls 19 of the lint filter 2 so that this or these edges are in proximity to the at least one filter wall 19 for removing the fluff.  The width of the scraper means 17 is sized to close the opening of the storage area 18 to avoid sucking scraped lint from the storage area 18 and to disturb the air flow through the lint filter 2 .  The width of the scraper means 17 may also be defined by the distance between two filter walls 19 when the fluff filter 2 is made up of a plurality of filter walls 19 arranged opposite one another.  In this way, the scraping means 17 makes it possible to effectively scrape the lint amassed on the filtering walls 19 of the lint filter 2.  The staple storage area 18 may be provided by a reservoir 13 connected to said fluff filter 2.  Thus, the storage tank 13 can be removed from the dryer to be emptied into a bin without the lint filter 2 removed from the dryer 1.  This tank 13 of lint may comprise a handle 12 to facilitate the gripping of the latter by the user.  The fluff tank 13 may comprise a rim on its upper part fitting into a groove in a structural element of the dryer 1.  The rim of the lint tank 13 thus allows said fluff tank 13 to slide inside the machine 1 and hold it in position.  The positioning of the lint reservoir 13 thus ensures that the lint 10 scraped by the scraping means 17 are collected in said lint reservoir 13.  The storage area 18 of the fluff is preferably placed under the lint filter 2 to collect the scraped lint falling by gravity.  This storage area 18 lint may have a capacity of the order of 1 to 2 liters.  Of course, this volume of the storage area 18 of the fluff is in no way limiting and may be of different volume.  The volume of the storage zone 18 is adapted to the shape of the air circulation ducts of the drying air circuit 5 and to the bulk of the dryer 1.  The storage zone 18 makes it possible to prevent fouling of the drying air circuit 5 during the duration of a drying cycle carried out by the machine 1.  This storage area 18 makes it possible to store a greater amount of lint than the amount of lint generated by a laundry drying cycle.  In this way, the storage area 18 does not need to be emptied and cleaned at each drying cycle of the laundry.  In the case where the user does not empty the storage area 18 after a drying cycle of the laundry, the dryer 1 does not go into safety at a subsequent start of a drying cycle of the laundry since said storage area 18 is not full.  In one embodiment of the invention, the frequency of the scraping operation of at least one filter wall 19 of the lint filter 2 can be determined from the quantity and / or the nature of the laundry introduced into the drum 6 for each of the drying cycles taken into consideration by control means of the machine 1 so as to evaluate the fouling of said at least one filter wall 19.  The determination of the quantity and / or the nature of the laundry introduced into the drum 6 can be carried out from one or more sensors connected to the control means of the machine 1 or else by a data input by the user on a control panel of the machine 1.  Many drying cycles of the laundry can be carried out by the dryer 1 before the storage area 18 is filled with 5 fluff.  According to the experiments carried out by the Applicant, a storage zone 18 with a volume of the order of 1.6 liters makes it possible to carry out a hundred laundry drying cycles.  While omitting to empty a traditional fluff filter will cause the dryer to fail because of detection of overheating of the circulating drying air.  Thus, the storage area 18 can contain the laundry fluff of several drying cycles implemented by the dryer 1 without user intervention and without risk of malfunction of said machine 1.  The fluff filter 2 may have various shapes and variations depending on the model of the dryer, while maintaining the cleaning performance of the fluff filter 2 by the scraping means 17.  The area covered by a filter wall 19 of the fluff filter may be of the order of 80 to 100 cm 2.  Of course, this surface of the filter wall 19 of the lint filter 2 is in no way limiting and may be of different size.  The surface of the filter wall 19 of the fluff filter 2 is adapted to the shape of the air circulation ducts of the drying air circuit 5 and to the bulk of the dryer 1.  The fluff filter 2 may also comprise two or more filter walls 19 so as to multiply the filtering surface of the air flowing in the drying air circuit 5.  The displacement of the scraping means 17 may be performed in a portion of a circle depending on the shape of the lint filter 2.  The fluff filter 2 may comprise one or more vertical filter walls 19 arranged facing each other.  The vertical filtering walls 19 comprise meshes or holes making it possible to collect the lint of laundry without obstructing the passage of the drying air.  The filtering vertical walls 19 comprise filter elements which can be in the form of fabrics fixed to a plastic structure of the lint filter 2.  The filter elements illustrated in FIG. 2 are in the form of a portion of a disc, but of course their shape is in no way limiting.  The shape of the scraping means 17 is adapted to cooperate with the shape of the lint filter 2, and particular to match the shape of the vertical filtering walls 19 of said lint filter 2.  The wall of the air outlet 8 of the tarnbour 6 is made in the form of grids to allow the introduction of the drying air flow F into the air outlet duct 11 and then through the fluff filter 2.  The drying air circulates inside the fluff filter 2, passes through the filter elements by depositing the lint on them and then the drying air is discharged into the drying air circuit 5.  The scraping means 17 is driven in displacement by a motor 14.  Preferably, the scraper means 17 is rotated about an axis of rotation 15 integral with the lint filter 2.  The housing 10 of the lint filter 2 is substantially quarter-cylinder shaped.  The circular part of the housing 10 of the lint filter 2 is adapted to allow the rotational drive of the scraper means 17 from a closed position B of an inlet opening 11 of the storage area 18 to a scraping position A of at least one filter wall 19 of said lint filter 2 and vice versa.  The scraping means 17 is in the closed position B of an inlet opening 11 of the storage area 18 when said scraper means 17 covers said inlet opening 11 of said storage area 18.  The scraping means 17 is in scraping position A of at least one filter wall 19 of the lint filter 2 when said scraping means 17 is situated outside the scraping surface of said at least one filter wall 19 of the filter. soft toys 2.  In the embodiment of the invention illustrated in FIGS. 3A to 3D, the scraping means 17 is in the closed position B of an inlet opening 11 of the storage area 18 when said scraping means 17 found in a substantially horizontal plane.  And the scraping means 17 is in scraping position A of at least one filter wall 19 of the lint filter 2 when said scraping means 17 at least partially obstructs the air inlet in the lint filter 2 from the air outlet pipe 7.  With reference to FIGS. 4A to 4C, the fluff filter 2 comprises two filtering walls 19 arranged vertically and along the vertical walls of said fluff filter 2.  The two vertical walls of the fluff filter 2 connect the rounded wall to the base of said fluff filter 2.  The base of the lint filter 2 rests on the storage area 18.  The scraping means 17 comprises two cutting edges 16 each cooperating with a filtering wall 19.  The cutting edges 16 of the scraping means 17 are placed on the ends of the width of said scraping means 17 and extend along the length of said scraping means 17.  With reference to FIGS. 5A to 5C, the fluff filter 2 comprises a filter wall 19 arranged vertically and along a vertical wall of said fluff filter 2.  The two vertical walls of the fluff filter 2 connect the rounded wall to the base of said fluff filter 2.  The base of the lint filter 2 rests on the storage area 18.  The scraping means 17 comprises a cutting edge 16 cooperating with the filtering wall 19.  The cutting edge 16 of the scraping means 17 is placed on one end of the width of said scraping means 17 and extends along the length of said scraping means 17.  Said at least one cutting edge 16 of said at least one scraping means 17 scrapes lint gathered on at least one filter wall 19 of said at least one lint filter 2 during movement of said at least one scraping means 17 in a first direction.  Said at least one cutting edge 16 of said at least one scraping means 17 slides on at least one filter wall 19 of said at least one lint filter 2 without scraping the lint accumulated during the movement of said at least one scraping means 17 in a second direction.  Thus, the lint amassed on said at least one filter wall 19 of the lint filter 2 is grouped by the movement of the scraping means 17 in a determined direction P to collect scraped lint in the storage area 18 only.  The scraping direction P of the lint amassed on the filtering walls 19 of the lint filter 2 is unique.  This scraping direction P of lint collected on the filter walls 19 of the lint filter 2 makes it possible to ensure that these lint do not return to the drying air circuit 5 and obstruct said filtering walls 19.  The scraping means 17 not only allows the lint collected on at least one filter wall 19 of the fluff filter 2 to be removed, but also to clean the walls of the fluff filter 2 in which said scraper means 17 is housed.  Thus, the scraper means 17 makes it possible to clean at least one filter wall 19 of the lint filter 2 but also to clean the chamber formed by said lint filter 2.  In this way, the lint from the fluff filter 2 from the drying air circuit 5 is removed by actuation of the scraping means 17 causing said lint to enter the storage area 18.  Said at least one scraping means 17 scrapes the lint gathered on at least one filter wall 19 of said at least one lint filter 2 during the driving of said at least one scraping means 17 of scraping position A of said at least one filter wall 19 at the closed position B of at least one inlet opening 11 of the storage area 18 of the scraped lint.  Thus, the fluff licks during the keyplacement scraper means 17 on said 5 at least one filter wall 19 of the lint filter 2 are collected in the storage area 18 by passing through the inlet opening 11 of said area storage 18.  The lint scraped by the scraping means 17 falls by gravity into the storage area 18.  Said at least one scraping means 17 slides on at least one filtering wall 19 of said at least one fluff filter 2 saris scrape lint gathered on said at least one filter wall 19 during driving of said at least one scraping means 17 of the closed position B of at least one inlet opening 11 of the storage area 18 of the scraped lint at the scraping position A of the at least one filter wall 19.  Thus, the scraper means 17 can not cause the fluff accumulated on said at least one filter wall 19 of the fluff filter 2 and therefore cause at least partial obstruction of the air outlet line 7 of the flapper circuit. drying air 5.  In this way, the fluff accumulated on said at least one filter wall 19 of the fluff filter 2 is directed to the storage zone 18 to be collected without being able to be returned to the drying air circuit 5 and consequently to cause losses during the circulation of air in said drying air circuit 5.  Said at least one cutting edge 16 of the scraping means 17 makes it possible to loosen the lint gathered on said at least one filter wall 19 of the lint filter 2 when the scraping means 17 is rotated from a scraping position A of said at least one filter wall 19 at a closed position B of at least one inlet opening 11 of the storage area 18 of the scraped lint.  Said at least one cutting edge 16 of the scraping means 17 makes it possible to slide on the lint amassed on said at least one filter wall 19 of the lint filter 2 when the scraper means 17 is driven in rotation from a closed position B of at least one inlet opening 11 of the storage area 18 of the scraped lint at a scraping position A of said at least one filter wall 19.  Said at least one scraping means 17 is rotated during the passage of a scraping position A of at least one filter wall 19 of said at least one lint filter 2 to a closure position B of at least an inlet opening of the storage area 18 scraped lint and vice versa.  The rotational drive of the scraping means 17 is provided by a motor 14.  The axis of rotation of the motor 14 is aligned with the axis of rotation of the scraping means 15.  The stop and start of the motor 14 for rotating the scraping means 17 is provided by a relay 20 electrically connected to said motor 14.  The relay 20 is controlled by control means of the dryer 1.  The motor 14 for rotating the scraper means 17 may be of the synchronous type.  In the case where the drive motor 14 for rotating the scraping means 17 is of the synchronous type, this motor 14 automatically reverses the direction of rotation of the axis of said motor 14 when an obstacle is detected.  In this way, the drive in rotation in opposite direction of the motor 14 as soon as an obstacle is detected makes it possible to avoid any damage to the fluff filter 2 and the dryer 1.  In addition, the motor 14 rotates the doctoring means 17 in the appropriate direction as soon as a limit stop or obstacle is detected.  In one embodiment of the invention, Figs. 4A to 4C illustrate the operation of the laundry dryer 1 so as to remove linted laundry fluff from the drying air flow through the drum 6.  In FIG. 4A, the flow of air F passing through the drum 6 is channeled into an air outlet duct 11 and then into a fluff filter 2.  The lint entrained by the flow of air F accumulates on the filtering walls 19.  The filtering walls 19 are two in number and arranged vertically.  The flow of air F passes through the filtering walls 19 and the fluff clings onto said filtering walls 19.  During the circulation of the air stream F in the fluff filter 2, the scraper means 17 closes an inlet opening 11 of the storage area 18 of the fluff.  The lint collected in the storage area 18 during previous drying cycles of the dryer 1 can not return to the drying circuit 5.  In FIG. 4B, the cutting edges 16 of the doctoring means 17 slide on two vertical filtering walls 19 of the lint filter 2 without scraping the lint accumulated on the filtering walls 19 during the driving of the scraping means 17 from the position shutter B of the inlet opening 11 of the storage area 18 of the scraped lint at the scraping position A of the filtering walls 19.  In FIG. 4C, the cutting edges 16 of the doctoring means 17 scrape the lint accumulated on the filter walls 19 of the lint filter 2 during the driving of the scraping means 17 from the scraping position A to the filtering walls 19 to the closed position B of the inlet opening 11 of the storage area 18 of the scraped lint.  Advantageously, said at least one fluff filter 2 is placed upstream of said at least one fan 9 of the drying air circuit 5.  Thus, the fan 9 of the drying air circuit 5 can not be clogged with lint of laundry since it is accumulated on the filter wall or walls 19 of the lint filter 2 and then collected in a storage area 18.  In addition, the storage zone 18 is closed at least during the operation of the fan 9 of the drying air circuit 5 preventing the return of fluff in the drying air circuit 5.  In this way, the fluff discharged into the drying air circuit 5 from the drum 6 is not stirred by a fan 9.  This positioning of the lint filter 2 upstream of a fan 9 makes it possible to avoid any risk of safety at the level of the fan 9, and in particular the clogging of the blades of a centrifugal type fan.  The position of the lint filter 2 avoids the risk of overheating of a fan 9 and its damage.  

In addition, the efficiency of the fan 9 of the drying air circuit 5 is constant and is not decreased because of the fouling of said fan 9. The dryer 1 comprises a display means and / or a sound means signaling the filling of the storage area 18 by the scraped lint.

Thus, the user of the dryer 1 is warned by a visual and / or audible means of the amount of lint of laundry stored in the storage area 18. The visualization means and / or sound perrnet signal to the user when the compacted lint storage area 18 needs to be emptied in order to maintain the drying performance of the dryer 1.

The display means may be realized by an indicator light or a pictogram on a display device symbolizing the maximum level of fluff stored in the storage zone 18 that is acceptable for normal operation of the dryer 1. The sound medium can be achieved by an audible alarm connected to a printed circuit board control means of the dryer 1. When the complete filling of the storage area 18 is reached and can be reported by visual means and / or sound, the user is obliged to empty the storage area 18 fluff to start a drying cycle under normal operating conditions of the dryer 1.

Advantageously, the storage area 18 scraped lint is extractable from a body wall 3 of said dryer machine 1. Thus, the user can easily access the storage area 18 to empty 2931489 -21- lint scraped and accumulated during the various drying cycles implemented by the dryer 1. The storage area 18 can be removed from the body 3 towards the front of the dryer 1, whatever front loading or top load laundry. Thus, access to the storage area 18 is easy and avoids disassembly of other elements of the machine 1 or the opening of an access door to the drum 6. Advantageously, said at least one filter wall 19 said at least one lint filter 2 is accessible and / or removable from said dryer 1 so that it can be cleaned. Thus, said at least one filter wall 19 can be cleaned by the user in the case where the meshes thereof are plugged with fluff and that cleaning additional to that performed by the scraping means 17 is necessary. Advantageously, said at least one fluff filter 2 is placed upstream of a condenser (not shown) of the drying air circuit 5. Thus, the condenser of the drying air circuit 5 can not be fouled by lint of laundry since these are accumulated on the filter wall or walls 19 of the lint filter 2 and then collected in a storage area 18. In addition, the storage area 18 is closed at least during the operation of the fan 9 of the drying air circuit 5 preventing the return of fluff in the drying air circuit 5 and more particularly in the condenser. The fluff filter 2 is placed upstream of a condenser that can be mounted in the drying air circuit 5 when it is a condenser dryer. In this way, clogging of the condenser lines is avoided and the efficiency of the dryer 1 is not impaired. In the case of a condenser dryer 1, the drying air passes through the condenser after passing through the fluff filter 2. Then, said drying air is recirculated to the drum 6 following passage in the condenser. In one embodiment of the invention, the cleaning operation of the lint storage area 18 is coupled with the cleaning operation of the condenser. In this case, the locking means of the storage area 18 and the condenser in the dryer 1 can be adapted to cooperate together. In this way, the user is obliged to clean the condenser and the storage area 18 at the same time. In the case of a dryer 1 drying machine, the drying air is discharged outside the body 3 of said machine 1 after having passed through the lint filter 2. The machine to dry the laundry 1 according to the invention may be equipped with a device for evacuating the drying air to the outside. The fluff filter 2 is disposed at the outlet of the drum 6 and upstream of the fan 9 in a dryer machine 1 to condensation or evacuation, as shown in Figure 1. In one embodiment of the In the invention, the lint storage area 18 may comprise a fluff discharge opening (not shown) which may allow the insertion of suction means, such as an aspirator. The lint storage area 18 includes a fluff discharge opening for emptying said storage area 18. This fluff discharge opening may be adapted to receive a suction pipe of a vacuum cleaner. In this way, the lint storage area 18 can remain in a housing in the dryer 1 to empty said storage area 18 without the user having to manually remove the lint. The fluff discharge opening of the storage area 18 may include a closure member. This closure element prevents the lint of laundry from leaving the storage area 18 unintentionally. The closure member of the fluff discharge opening may be made of a flexible membrane made of a plastic material, such as rubber. The flexible membrane of the closure element may comprise slots to allow the opening of said membrane during the insertion of a suction pipe inside the storage area 18.

A method of removing lint in a dryer according to the invention will now be described. The method comprises at least one step of scraping said at least one fluff filter 2 during at least one reversal of the direction of rotation of said at least one fan 9 implemented during a laundry drying cycle.

Thus, the scraping of the lint filter 2 by the scraping means 17 is implemented when the air flow of at least one fan 9 of the drying air circuit 5 is reduced. Therefore, the lint of laundry is less strongly sucked by the fan 9 of the drying air circuit 5 and the effort to exert to take off the lint of laundry pressed against at least one filter wall 19 of the lint filter 2 is minimized . In this way, the lint is easily peeled off from at least one filter wall 19 of the lint filter 2 to be discharged into a lint storage area 18 in the dryer 1. drying machine 1 thus makes it possible to scrape the lint of linen gathered on a filter 2 and to move these lint loads to store them inside a storage area 18 of said machine 1. These lint of Linens are thus stored for several drying cycles before being removed by the user outside the dryer 1 in a garbage bin. In addition, the traditional lint pickup with the user's fingers against the lint filter is replaced by the rubbing of the scraping means 17 moving along the lint filter 2, thus facilitating the operation. The scraping means 17 makes it possible to reduce the stress associated with the elimination of the lint of linen gathered on the lint filter 2 by allowing said lint filter 2 to be cleaned at each drying cycle of the laundry or at a determined cleaning frequency. . The lint of laundry is thus stored in a storage area within the dryer 1 for several drying cycles of the laundry prior to disposal by the user in a bin. The scraper means 17 facilitates the cleaning of the lint filter 2. Furthermore, the dryer 1 is adapted to receive lint filters of various shapes and sizes cooperating with scraper means 17. Preferably, the lint storage area 18 is arranged outside the fluff filter 2 and below the latter allowing the passage of drying air through said filter 2 during a drying cycle of the laundry to ensure circulation of drying air normal in the drying air circuit 5 and to collect new lint of laundry on said lint filter 2. The lint filter 2 comprising a scraping means 17, according to the invention, allows to guarantee the drying of the items of laundry by an optimal circulation of the drying air in the drying air circuit 5. The fluff filter 2 allows a passage of the drying air without creating a loss of charges related to the pelu accumulated on it and then collected in a storage area 18. 30 The lint of laundry scraped by the scraping means 17 falls by gravity into the storage area 18. The step of scraping said at least one lint filter 2 is implemented when said at least one fan 9 operates in the direction of rotation opposite to the direction of rotation of operation having a maximum air flow. Thus, the scraping of the lint of laundry on at least one filter wall 19 of the lint filter 2 is facilitated by the reduction of the pressure exerted by the air circulation implemented by at least one fan 9 of the air circuit. The laundry fluff is pressed onto at least one filter wall 19 of the fluff filter 2 while allowing effective cleaning of the scraper means 17 moving along the surface of the at least one wall. In practice, the drum 6 and said at least one fan 9 are jointly driven in rotation. An engine (not shown) allows the driving of the drum 6 for brewing the laundry with alternating rotation to prevent the knotting of the laundry. The motor can also drive one or two fans 9. Both fans can be centrifugal technology. The air flow of the fan 9 is greater in a positive direction relative to a negative direction called negative. The air flow factor between the positive direction and the negative direction of this fan 9 is substantially of the order of 3. Advantageously, said at least one step of scraping said at least one lint filter 2 is implemented when several reversals of the direction of rotation of said at least one fan 9 of a laundry drying cycle, and preferably between 2 and 4 inversions of the direction of rotation of said at least one fan 9 of a laundry drying cycle. Thus, said at least one filter wall 19 of the lint filter 2 is scraped several times by the scraper means 17 during a drying cycle of the laundry 20 carried out by the dryer 1. in a manner, said at least one filter wall 19 of the lint filter 2 is cleaned regularly and the air flow in the drying air circuit 5 is optimally ensured throughout a drying cycle carried out by In FIG. 3A, the scraper means 17 is in the closed position B of an opening 11 of the storage zone 18. This closed position B is taken by the scraper means B intervenes during a drying cycle carried out of the dryer 1 and particularly during the operation of at least one fan 9 of the drying air circuit 5. the inlet opening 11 of the storage area 18 by the scraper means 17 can be maintained throughout the period of air circulation in the drying circuit 5 and / or during all the air flow generated by at least one fan 9 rotated in the positive direction. During the circulation of air in the drying air circuit 5 generated by at least one fan 9 rotated in a negative direction, the scraper means may be moved to scrape the linted amids onto the at least one filter wall 19 of the lint filter 2. The closure of the inlet opening 11 of the storage area 18 by the scraper means 17 can also be maintained between two drying cycles of the machine. drying the laundry 1 so that dust from the storage area 18 can not spread outside thereof. In FIG. 3B, the scraping means 17 are in scraping position A of at least one filter wall 19 of the lint filter 2. The scraping means 17 is preferably outside the surface of at least one filtering wall 19 so as to take off all the lint amassed on said at least one filter wall 19. In Figure 3C, the scraper means 17 is rotated by the motor 14 about an axis of rotation 15 between the position of scraping A of at least one filter wall 19 of the fluff filter 2 and the closure position B of an opening 11 of the storage area 18. The fluff of the laundry is peeled off from the at least one filter wall 19 as and as the advancement of the scraping means 17. The fluff of the laundry accumulates between them so as to form balls of fluff. In FIG. 3D, the lint of linen is peeled off from the at least one filter wall 19 and is compressed together to fall into the storage zone 18. The scraping means 17 has returned to the closed position B of an opening 11 of the storage area 18.

In an improved embodiment of the invention, said at least one scraping means 17 compresses lint scraped in a storage area 18. Thus, the dryer 1 can scrape the lint of linen collected on a filter 2 and to compress these lint of laundry for storing inside said machine 1. These lint of laundry are thus stored for several drying cycles before being eliminated by the user outside the machine. dry the laundry 1 in a bin. The lint of laundry is compacted by the scraping means 17 to minimize the storage space of these lint. Thus, the volume of the storage area 18 can be reduced and / or the amount of stored lint of laundry larger. In another embodiment of the invention, the scraping means 17 may be driven in displacement by the drum 6, or by a motor of at least one fan 9 of the drying air circuit 5 coupled to a device disengagement, or by a wax cylinder, or a linear electric motor.

In another embodiment of the invention, the scraping means 17 can be driven in translation in the fluff filter 2. A low position of the scraping means 17 makes it possible to close an inlet opening 11 of the scraper zone. storage 18. Reciprocating movements from a low position to a high position make it possible to scrape at least one filter wall 19 of the lint filter 2. Said at least one scraping means 17 is driven in translation during the passage of a scraping position A of at least one filter wall 19 of said at least one fluff filter 2 at a closure position B of at least one inlet opening 11 of the scraped lint storage area 18 and Conversely. A lint filter according to the invention thus makes it possible to prevent the dryer 1 from indicating a malfunction on the control panel by a signaling and / or audible means and that the control means of said machine 10 1 stop the drying cycle of the current laundry waiting for troubleshooting for the detected fault. Thus, a drying machine according to the invention, and as described above, avoids increasing the duration of a laundry drying cycle or a risk of engagement of a safety thermostat .

The fluff filter according to the invention makes it possible to produce simple drying machines which are easy to industrialize and economical. Moreover, these clothes drying machines according to the invention are practical and simple in their use.
