Description

The present invention relates to a device for opening a door of

  drum. It also relates to a rotary drum door opening process, especially for washing machine and / or tumble drying.

  The present invention generally relates to a washing machine and / or dryer laundry equipped with such a device for opening a drum door. This washing machine and / or drying machine comprises a tank in which is housed the drum for containing the laundry. This tank must be tightly closed when using the machine and / or drying the laundry.

  In general, the present invention is applicable to a washing machine and / or drying the laundry, provided with a rotary drum with radial loading, through an opening provided in the drum shell.

  Thus, the loading and removal of the laundry drum is performed at the perimeter of the drum, and generally from the top of the machine. The latter having in the upper plane of its body a door allowing access to the drum.

  In the vast majority of cases, this rotary drum is equipped with a double-leaf door, these leaves being articulated independently respectively at the two opposite edges of the opening. Conventionally, each leaf is mounted by one of its sides in rotation about an axis integral with an edge of the opening.

  The opening of these leaves is generally achieved through the implementation of resilient return means mounted at the axis of rotation, and the holding in the closed position of these wings is achieved by complementary closure means mounted respectively on the free edges of the leaves. The movement of the leaves is generally independent and requires the use of two hands to bring the leaves in closed position.

  A disadvantage of such a washing machine and / or drying the top loading laundry is that it is necessary to open at least two doors. The user must indeed open the access door of the body and the door of the drum. In some cases, the opening of a second door of the tank of the machine is necessary before opening the drum door and after opening the door of the body described above. This sequence for opening the washing machine and / or drying the laundry thus comprises three manipulations. These manipulations for the user are very restrictive.

  In addition, the opening of the drum is quite often complicated and even possibly harmful, especially at the level of the fingers.

  However, it is known, as described in document EP 1 422 333, a machine to wash and / or dry the laundry whose flaps of the rotary drum are opened by a system of rods. The connecting rods connect the opening handle of the door of the bodywork to unlocking means of the doors of the rotary drum door, so that at the opening of the washing machine and / or drying the laundry, only the opening of the door of the bodywork is necessary. Nevertheless, for closing the machine, two manipulations are required.

  However, the opening of the drum door is dependent on the opening of the door of the body by the user. The connection between the door handle of the bodywork and the drum door is complex and expensive. This mechanical connection requires linkages articulated between them to allow the transmission of movement from the bottom to the top of the handle of the bodywork door by rotations to allow the support of a finger on an unlocking means. This system does not allow automatic opening of the drum door.

  In addition, the opening system of the drum door is located in the center of the door of the body and crosses the integrated product tray in the door of the body, which makes it visible and unattractive.

  Thus, due to the passage of the opening system of the drum door through the product box, it is necessary to provide a seal on the finger actuating the unlocking means of the flaps of the drum door.

  The present invention aims to solve the aforementioned drawbacks and to provide a device for opening the drum door generally facilitating access to the interior of the drum for the user.

  For this purpose, the present invention relates to a device for opening a rotary drum door of horizontal axis comprising at least one leaf having opening means, a tank surrounding the rotary drum, an unlocking means disposed on the rotary drum, means for actuating the unlocking means of the rotary drum flap integrated on the inner face of the tank, means for rotating the rotary drum and means for opening the tank to access the drum. rotating drum.

  According to the invention, this device for opening a drum door further comprises two means for positioning the drum, a first positioning means allowing the drum to be placed in relation to said means for actuating the drum of the drum. drum, and a second positioning means for placing the opening of the drum vis-à-vis the opening of the tank after the means of unlocking the drum leaf has been actuated.

  By mounting this device on a washing machine and / or drying the laundry, the flap or doors of the drum door are automatically opened and resting on the edges of the tank so that the user of the machine No manipulation to be made at this drum door for the positioning of the drum. This invention allows the locking of the drum when loading and unloading the laundry.

  In addition, the drum door with the opening device is adapted to receive one or two leaves.

  According to a preferred characteristic of the invention, the actuating means are motorized.

  Thus, the opening of the drum door can be automated so that the user has no manipulation to perform at this drum door. The opening of this door can also be done manually in a simple manner. And the closing of the drum door does not require special efforts.

  According to another aspect of the invention, it relates to a machine for washing and / or drying laundry, comprising a rotating drum mounted inside a washing tub, said washing tub being incorporated into a machine body. This machine comprises a device for opening the drum door according to the first aspect of the invention.

  Such a washing machine and / or drying the dishes has the same characteristics and advantages similar to those described above.

  According to a third aspect of the invention, it relates to a method of opening a rotary drum door of a washing machine and / or drying laundry comprising a washing tub, a drum opening comprising at least one leaf having opening means, unlocking means disposed on the drum flap, means for actuating the integral drum leaf unlocking means on the inner face of the bowl, means for rotating the drum and means for opening the tank to access the drum.

  This method of opening a rotary drum door comprises the following steps: - positioning of the drum vis-à-vis the actuating means of the unlocking means of the drum flap; unlocking the wing by the means for actuating the means of the unlocking means of said drum leaf; - Rotation and positioning of the drum vis-à-vis the opening of the tank, and opening the flap of the drum door by means of opening the leaf.

  Thus, the opening of the drum door can be performed automatically and invisibly for the user before unlocking the access door of the machine, so that the door can be opened as soon as the end of the door is detected. washing cycle or drying.

  Other features and advantages of the invention will become apparent in the description below.

  In the accompanying drawings, given by way of non-limiting example: FIG. 1 is a perspective view of an open drum adapted to equip a washing machine and / or drying the laundry and mounted in a washing or drying tub according to FIG. an embodiment of the invention; - Figure 2 is a schematic side view of a washing machine and / or tumble dryer according to one embodiment of the invention; FIG. 3 illustrates in perspective a drum equipped with a drum door system according to one embodiment of the invention; - Figures 4 to 9 are schematic sectional views illustrating the opening of a drum door according to the invention.

  Firstly, with reference to FIGS. 1 and 2, a drum door according to one embodiment of the invention will be described.

  The drum 2 as illustrated in Figure 1 is a drum for receiving laundry either in a washing machine, or in a dryer or a washer-dryer, the ferrule 6 being in these cases perforated. These washing and / or drying machines are of the top loading type.

  These machines for washing and / or drying the laundry comprise a body 25 comprising an access opening 10 inside the body 25. In these machines for loading from above, this opening 25 is made in an upper portion of the body. body, and in this example, in an upper plane of the bodywork 25.

  An access door 26 is adapted to close this opening 10 of the body 25 of the machine, especially during operation thereof.

  In particular, in known manner, this access door 26 is associated with locking means whose operation is related to the operation of the machine.

  Thus, at the beginning of the washing or drying cycle, the locking means are actuated to prevent the opening of the access door 26. Similarly, at the end of the washing or drying cycle, the locking means are deactivated for allow the user to open the machine.

  In this embodiment, and in no way limiting, the access door 26 is pivotally mounted about an axis of rotation 27 integral with the bodywork 25 of the machine.

  The body 25 of the machine is adapted to house a tank 1 which is adapted in particular to contain the different wash and rinse baths.

  The drum 2 is intended to be mounted in rotation inside a tank 1 of the machine around a horizontal axis 33.

  Note that Figure 2 is schematic and that many organs necessary for the operation of the machine (and for example engine, pumps, filters, ...) have been omitted and do not need to be described in detail here.

  The ferrule 6 of the drum 2 has an opening 9 closed by a door allowing the introduction and removal of the laundry inside said drum 2. This door comprises two leaves 3 and 4. A first leaf 4 is rotatably mounted around the door. an axle 18, as commonly used for gates of a washing machine drum and / or tumble dryer. Said first wing 4 will be designated in the remainder of this document by beating before. This front flap 4 is placed closest to the user when the drum door 2 is in the open position.

  This is a conventional assembly of a front flapper 4 rotating about an axis 18, as commonly used for the gates of a washing machine drum and / or tumble dryer.

  In order to facilitate the opening of the leaf, and the rotation of this front leaf 4 about the axis 18, it is conventional to mount a torsion-mounted return spring 29 for exerting a rotational force about the axis 18.

  The second wing 3 is rotatably mounted about an axis 17 with a return spring 29 as described for the first front wing 4. Said second wing 3 will be designated in the remainder of this document by rear wing. This rear flap 3 is placed farthest from the user when the drum door 2 is in the open position.

  Any type of hinge can make it possible to mount this rotation of the leaves 3 and 4 along the edges of the opening 9 of the drum 2.

  These leaves 3 and 4 are articulated independently respectively at two opposite edges of the opening 9 of the drum 2.

  Conventionally, each leaf 3 and 4 is mounted by one of its sides in rotation respectively about an axis 17 and 18 integral with the edge of the opening 9 of the drum 2.

  Figure 1 illustrates such a drum 2 mounted inside a tank 1 of a washing machine and / or drying laundry, loading from above.

  This drum door 2 makes it possible to close an opening 9 made in the drum 2 and disposed substantially in line with the access opening 10 of the body 25 of the machine.

  This drum door 2 can thus be movable between a closed position in which it closes the opening 9, and an open position in which the leaves 3 and 4 are disposed between the wall of the tank 1 and the body 25 of the machine.

  This open position of the leaves 3 and 4 is illustrated in particular in FIG.

  In another embodiment, the two-leaf drum door 2 and 3 can be modified to a single-leaf drum door. This single wing may consist of one or more removable parts. When opening the drum door 2 about the axis of rotation 17, the leaf is located towards the rear of the machine so that the user is not bothered by this door to have access to the inside of the drum 2.

  FIG. 3 shows in isolation FIG. 2 the drum 2 according to the invention equipped with a drum door system 2.

  The drum 2 in this example has a cylindrical wall, ferrule 6, so that the leaves 3 and 4 of the door also consist of a cylinder portion adapted to close an opening 9 of the ferrule 6.

  This type of door opens on the outside and requires a free space on the surface of the machine in order to be able to be maneuvered.

  Such a drum door 2 is closed by means of a lock comprising a fastening system consisting of a bolt 24 adapted to cooperate with a strike 23 associated.

  These leaves 3 and 4 are unlocked by an actuating means 5 of the unlocking means 20 and moved in rotation by means of elastic return means 11.

  The actuating means 5 of the wings 3 and 4 which will be described later are arranged in the upper part of the tank, and as illustrated in FIG. 2, between the tank 1, the bodywork 25 and the access door 26.

  As well illustrated in FIG. 1, the device for opening the drum door 2 also comprises first positioning means 8 for the drum 2. These first positioning means 8 are adapted to position the opening 9 of the door in rotation. of the drum 2.

  As is well illustrated in FIGS. 4 to 9, the first positioning means 8 of the drum 2 consist of two housings 19 formed on the pulley 22 driving rotation of the tank 1 and the drum 2.

  In this example, the housing 19 for positioning the drum 2 are arranged so that their center is aligned on the same circle of the same diameter and center of axis 33. In this embodiment, the angular orientation between the two Drum positioning slots 19 is 31 ".

  These housings 19 for positioning the drum 2 are adapted to receive a locking finger 13 of the drum 2.

  To allow the positioning of the drum 2, the pulley 22 driving rotation of the tank 1 and the drum 2 may comprise a groove adapted to slide the finger 13 during the rotation of the drum 2.

  The first housing 19 for positioning the drum 2 makes it possible to block said drum 2 in such a way that the actuation means 5 is facing the unlocking means 20 of the leaves 3 and 4. The unlocking means 20 may, for example, be a push button 32 or a spring blade.

  The actuating means 5 are in this embodiment adapted to act on the front flap 4 of the drum 2, opposite to the rear flap 3 described above.

  Said actuating means 5 of the unlocking means 20 are situated around the periphery of the tank 1 and in the portion above the horizontal plane 28 passing through the axis of rotation 33 of the drum 2.

  These actuating means 5 comprise firstly a finger 12 in a slide 30 driven in translation by a jack 31.

  The finger 12 may be provided with an elastic return means to return to the rest position. Hence, the cylinder 31 may be a single-acting cylinder and powered electrically.

  This finger 12 can also be set in motion by a gear system.

  The second housing 19 for positioning the drum 2 makes it possible to block said drum 2 in such a way that the opening 9 of the drum 2 is opposite the opening 10 of the vessel 1.

  The leaves 3 and 4 move between the first and second locking position of the drum 2 by sliding along the vessel 1.

  Preferably, the finger 13 is moved by a movement back and forth in a groove in a pulley 22 for driving the drum 2 having two housings 19 corresponding to the two positions of the drum 2.

  In a second embodiment, the finger 13 is moved by a movement back and forth in a groove formed in a flange 15 of the drum 2 having two housings 19 corresponding to the two positions of the drum 2.

  In a third embodiment, the finger 13 is displaced by a movement back and forth in a groove formed in the shell 6 of the drum 2 having two housings 19 corresponding to the two positions of the drum 2.

  In addition, the positioning means 8 can be motorized.

  In a fourth embodiment, the positioning means 8 are provided by a drive means 7 in rotation of the drum 2 for locking said drum 2, such as a direct drive type motor.

  We will now describe a method of opening a drum door according to the invention.

  This opening is implemented after detecting an end of washing or drying cycle. This type of detection is conventionally implemented in a washing machine and / or drying the laundry to allow the opening of an access door 26 of the bodywork 25 at the end of a washing or drying cycle.

  The opening of the drum door 2 is preferably implemented even before the unlocking of the access door 26, so that the drum door 2 is open when the user has access to the machine.

  In a variant of this method of opening a drum door, the order of the automatic opening of the drum door 2 is given by pressing a control button.

  A first step of positioning the drum 2 is necessary to lock said drum 2 so that the front leaf 4 is opposite the actuating means 5 of the unlocking means 20.

  When opening the drum door 2, the actuating means 5 of the unlocking means 20 first of all translate a finger 12 downwards in order to bear on the pushbutton 32 placed on the front leaf 4 of the drum 2.

  Thus, the bolt 24 is extracted from the striker 23 and the leaves 3 and 4 are pushed towards the inside of the drum 2 as illustrated in FIG. 5 until the end of the stroke of the electric jack 31 controlling the finger 12 of unlocking.

  As a result, the bolt 24 of the front leaf 4 begins to disengage the striker 23 of the rear leaf 3 as shown in Figure 5. Then, the return springs 29 of each of the two leaves 3 and 4 force them to opening with a suitable torque.

  Under the effect of the thrust of the return spring 29 of the rear leaf 3, said rear leaf 3 continues its opening movement. The bolt 24 is released from the striker 23.

  The rear flap 3 comes into contact with the tank 1. While the front flap 4 remains in contact with the unlocking finger 12.

  Due to the restoring force exerted by the spring 29, the rear leaf 3 is in a slightly open position as shown in FIG.

  The electric cylinder 31 controlling the electric finger 12 returns to the rest position as soon as the end of travel of said electric cylinder 31 is detected. This return of the finger 12 in the initial position is achieved by the retraction of the rod of the cylinder inside the casing of said cylinder 31. The front leaf 4 comes into contact with the rear leaf 3 itself in contact with the washing tub 1 as shown in Figure 7.

  In a variant of the embodiment, the return of the finger 12 is achieved by elastic return means such as a coil spring.

  Simultaneously, the detection of end of stroke of the finger 12 in the rest position causes the unlocking of the positioning means 8 of the drum 2 as illustrated in the position of FIG. 8.

  The finger 13 is then free and can slide in a groove in a pulley 22 for driving the drum 2.

  The drum 2 is then rotated to the second position as shown in FIG. 9.

  The leaves 3 and 4 slide along the ferrule of the washing tub 1 during the step of rotation between the positioning phase of the drum 2 vis-à-vis the actuating means 5 of the unlocking means 20 the flap 4 of the drum 2 and the positioning of the drum 2 vis-à-vis the opening 10 of the vessel 1.

  The drum 2 is again blocked by the finger 13 which fits into the second positioning housing 19.

  The leaves 3 and 4 are ajar and in contact with the periphery of the opening of the washing tub 1 as illustrated in FIG. 9.

  In a variant of the embodiment, the locking of the drum 2 is achieved by the rear flap 3 while resting on the vessel 1.

  The user can now access the inside of the drum 2 by opening the access door 26. The leaves 3 and 4 are released from the stresses exerted by the access door 26 and can continue their opening by the return means elastic 11.

  Thanks to the invention, a device for opening the drum door 2 is thus obtained, which automatically allows the unlocking and opening of the drum door 2 to be obtained at the end of a washing cycle.

  Thus, this drum door can be opened without requiring manipulation on the part of the user.

  In addition, thanks to the conventional detection means for locking the access door 26 of the body, this opening of the drum door 2 can be performed as the access door 26 of the body is closed, so that that the user does not have access to this drum door 2.

  The detection of the end of the opening cycle of the drum door 2 gives the authorization of the unlocking of the access door 26.

  The closure of the drum door 2 is compatible with conventional means for closing a drum door 2.

  A drum door 2 comprising a single leaf 4 is adapted to this opening device. The invention can be applied to a single leaf door 4 since the operating principle is similar to that of a drum door 2 comprising two leaves 3 and 4.

  In addition, the invention operates regardless of the direction of rotation of the drum 2, insofar as the actuating means 5 of the unlocking means 20 can locate on either side of the opening 10 of the vessel 1. At the end of a cycle or on a stop command, it is therefore not necessary to impose a direction of rotation prior to allowing the door opening of the rotary drum 2.

  Of course, the present invention is not limited to the embodiments described above.

  In particular, the actuating means 5 of the unlocking means 20 of the leaves 3 and 4 using a jack 31 could be replaced by other mechanisms allowing the movement of the finger 12 and the automatic unlocking of the wings 3 and 4 of the drum 2.

  In addition, the means for locking the wings 3 and 4 composed of a bolt 24 and a striker 23 disposed in the center of the leaves 3 and 4 may be replaced by a multiple or single hook system associated with a push button 32 or a blade spring and arranged on the ends of the leaves 3 and 4.
