Definitions
- the invention relates to a washing machine of the type in which the laundry is received in a likely drum to be driven in a rotational movement around an axis substantially horizontal, inside a fixed tank.
- the invention relates to a washing machine of this type, in which the laundry is loaded and discharged through at least one access door outside provided in the fixed tank and at least one drum door provided in the circumferential wall of the drum.
- the invention applies in particular to washing machines of large capacity and very large capacity, such as those that are used in communities.
- the inside of the drum is sometimes divided in two compartments by a radial partition, access each compartment being secured by a door separate drum.
- the tank is then equipped with two external access doors, respectively intended for loading and unloading of linen.
- washing machines in which the entry and exit of the linen is carried out by a single front door placed in the axial extension drum, washing machines in which loading and the unloading of the laundry is done from above or from the side have the advantage of allowing the drum support at both ends.
- load washing machines have the advantage of allowing easy access inside the drum by opening a door unique.
- access to the interior of the drum requires on the contrary the successive opening the exterior access door and the drum.
- the door of the drum In loading and unloading from above or from the side, the door of the drum usually includes two hinged leaves on the circumferential wall of the drum in pairs hinges oriented parallel to the axis thereof.
- the door locks and unlocks are ensured by a mechanism interposed between the two and which can take different forms.
- a first locking mechanism frequently used, includes claws that make protruding outward along the edge of one of the doors of the drum door, so that penetrate notches formed in the edge adjacent to the other wing.
- To unlock the mechanism it is necessary to press a mounted button on the leaf with the claws, so as to make pivot the two leaves of the door slightly towards the inside of the drum to release the claws of the notches.
- the other door leaf then opens automatically under the action of torsion springs associated with its hinge. The same is true of the clapper wearing the claws, as soon as the button ceases to be hurry.
- the mass of laundry treated during each wash-spin cycle is important and the peripheral speeds reached by the wall circumferential of the drum during the final spin are very large.
- the laundry is therefore subjected to a force centrifugal as it is in the form of a hard "wafer", glued against the cylindrical wall of the drum, when all washing operations and are finished. Since the door of the drum is integrated in the cylindrical wall, the laundry slab is also formed behind this door. Because unlocking the door drum requires a depression of its two leaves, the laundry cake formed at the end of the wash-spin cycle constitutes an obstacle which makes the opening of the door all the more difficult as the ability of the machine increases.
- the subject of the invention is precisely a top loading and unloading washing machine or from the side, in which access to the drum is at least as easy as in a front loading washing machine, regardless of locking mechanism of the drum door, including understood when this mechanism is a claw mechanism the unlocking of which forces the leaves to be pushed back inward of the drum.
- a washing machine comprising a tank fixed and a drum able to rotate inside the tank, the tank including at least one access opening bounded by a frame and normally closed by a exterior access door and the drum including a circumferential wall and at least one door of drum mounted on this wall so that it can be brought in front of the exterior access door, by a drum rotation, the washing machine being characterized by the fact that it also includes means automatic opening of the drum door, said automatic opening means including means of unlocking the drum door mounted on a support linked to the tank and constituted by the access door outside or by a retractable support, able to come place itself in the access opening of the tank, when the exterior access door is open.
- the retractable support is, for example, articulated on the frame, delimiting the access opening, so that it can be placed at the outside of the tank when the access door outside is closed.
- the invention advantageously applies to the case where the locking mechanism of the drum door includes claws and a button mounted on a first door leaves and notches formed in the other flying.
- the means of release include an actuator, provided with a push rod oriented substantially radially by relative to the axis of the drum, in the active position of the support.
- the push rod is then able to press the button mounted on the first door leaf of the drum.
- the actuator is then mounted either inside the exterior access door, or outside of this door, this door then tightly crossed by the push rod.
- the means of release include an actuator capable of control the rotation of a rotary shaft mounted on the support.
- the rotary shaft then carries a lever capable of press the button mounted on the first leaf of the door.
- drum door locking mechanism includes a pivoting link carried by a first door leaves and the ends of which cooperate with two bolts that slide on it beating, parallel to the axis of the drum, so as to ability to penetrate holes formed in ears attached to the circumferential wall of the drum.
- the means of release include an actuator with a rod, axially movable and rotating, and oriented substantially radially with respect to the axis of the drum, in the active position of the support.
- the rod carries at its end a dog suitable for training in rotating the swivel link, after the gripper has been brought into contact with this link by a translation of the rod.
- the invention also applies to a washing machine in which the door locking mechanism of the drum includes a slide that slides on a first leaf of the door, parallel to the axis of the drum, and locking rivets linked to the other wing and likely to penetrate into slots formed in the slide.
- These slots feature narrow parts ensuring locking when the rivets are there and enlarged parts suitable for be crossed by the rivets to allow the pivoting of the door leaves.
- the means of release include an actuator capable of control the rotation of a rotary shaft mounted on the support, orthogonal to the axis of the drum.
- the tree then carries a lever which cooperates with a formed stop on the slide, so you can order it sliding in the unlocking direction.
- the invention also applies to the case a washing machine with a revolving door a locking mechanism comprising hooks pivotally mounted on a first leaf of the door and interconnected by a control rod articulated, as well as locking rivets linked to the other wing and with which the hooks can come into engagement.
- the means of release include an actuator capable of control the rotation of a rotary shaft mounted on the support, orthogonal to the axis of the drum.
- the tree then carries a lever capable of engaging on a stop formed on the rod articulated on the hooks.
- these guide means may include ramps carried by the support unlocking means, that is to say as the case may be by the external access door or by the support retractable.
- means of pre-closing of the first leaf of the drum door can advantageously be provided. These means are then mounted on the frame which delimits the opening access. They can include a second actuator, mounted outside this frame and provided a push rod that crosses the frame so waterproof, in a substantially orientation tangential to the drum.
- the means for guiding the door leaves drum can be active means, allowing both to control the opening of the leaves of the door after unlocking and ensuring its automatic closing.
- the guide means flaps then include arms mounted pivoting on the frame defining the access opening, around two axes substantially parallel to the axis of the drum, and at least one second actuator capable of command a controlled pivoting of the arms, in the direction opening and closing direction doors.
- the arms are then fixed on two trees oriented parallel to articulations to the drum shaft.
- the two trees can then be linked one to the other in rotation, in opposite direction, by a mechanism on which a second single actuator acts.
- a mechanism on which a second single actuator acts In the when the door locking mechanism drum is a claw mechanism, its locking automatic can be achieved by means of a third drum door locking actuator, also mounted on the tank. This third actuator can possibly be the same as the first actuator which unlocks the door.
- the two trees carrying the arms which guide the door leaves drum can be rotated in direction reverses separately by two second actuators.
- the reference 10 designates generally a washing machine drum. This drum 10 is mounted so that it can be turned in one and the other direction around a substantially horizontal axis, at the interior of a generally designated fixed tank by the reference 12 in Figures 3 and 4.
- the invention relates to a washing machine in which the loading and unloading of linen is carried out by from above or from the side.
- the fixed tank 12 is equipped with one or two doors as appropriate external access 14 ( Figures 3 and 4).
- the drum 10 comprises, as the case may be, one or two drum doors 16, mounted on the wall circumferential 18 of the drum 10.
- the door external access 14 includes a single leaf 30, articulated by a hinge 32 on a frame 34 which makes integral part of the tank 12.
- This frame 34 delimits internally an access opening 36 which is closed through door 14 when it is in position closed.
- a pivoting of the leaf 30 of the door 14 towards the exterior around the hinge 32 allows the contrary to clearing the access opening 36. It is then possible to access the interior of the drum 10 when the drum door 16 is opposite access opening 36.
- an indexing system (not shown) automatically brings door 16 opposite from access opening 36 at the end of the wash-spin.
- the door to drum 16 comprises two leaves 20a and 20b, articulated on the circumferential wall 18 of the drum 10 by two hinges 22 oriented parallel to the axis of the drum.
- Each of the hinges 22 includes torsion springs (not shown) which tend to open the leaves 20a and 20b of the drum door 16, i.e. rotate them outwards drum around the hinges 22. In this open position of leaves 20a and 20b, one opening of substantially rectangular access practiced in the circumferential wall 18 is released, which allows to access the interior of the drum 10.
- the two leaves 20a and 20b of the door drum 16 are able to be held in position closed by a claw locking mechanism.
- This classic mechanism includes claws 24, fixed on the outer face of the leaf 20a, close to its edge adjacent to the leaf 20b. These 24 claws make protrudes radially outwards, so that ability to penetrate notches 26 formed in vis-à-vis the claws in the leaf 20b. Shapes complementary to the claws 24 and the notches 26 are such that the two leaves 20a and 20b are maintained practically in line with the wall circumferential 18 of the drum, under the action of torsion springs associated with the hinges 22, when the claws are received in the notches.
- unlocking can only be obtained by doing pivot the leaf 20a towards the inside of the drum, in order to release the claws 24 from the notches 26.
- a button 28 is mounted on the leaf 20a of the door, near the edge of this leaf carrying the claws 24. This classic arrangement is normally intended to allow manual unlocking of the door, by pressing a button 28.
- the washing machine incorporates automatic opening means of the drum door 16.
- the locking this door is a claw mechanism as illustrated in Figures 1 and 2
- the presence of automatic opening means eliminates difficulties posed by the presence of a hard sheet of laundry glued to the inside of the door and opposing the unlocking it, on large machines and very large capacity.
- the automatic opening means according to the invention allow access to the interior of the drum too easily than on a front-loading washing machine.
- the means for automatically opening the door drum 16 include unlocking means which include a first actuator 38 constituted for example by a double-acting linear cylinder.
- the first actuator 38 is mounted either directly on the door external access 14, as illustrated in FIGS. 3 and 4, either on a retractable support 132 capable to be brought into the access opening 36 after opening of this door 14, as illustrated by Figures 16 and 17.
- the first actuator 38 is provided with a rod pusher 40 whose end is turned towards the interior of the drum and equipped with a nozzle 41 capable of press button 28, as illustrated in the figure 2.
- the mounting of the actuator 38 is such that the axis of the push rod 40 is oriented substantially radially with respect to the axis of the drum 10 when the external access door 14 is closed ( Figures 3 and 4) or when the retractable support 132 is in the active position ( Figures 16 and 17).
- the mounting the actuator 38 on the access door outside 14 or on the retractable support 132 is such that the end piece 41 is located opposite the button 28 when the drum door 16 is opposite the opening access 36.
- the leaf 20b of the drum door 16 is released and opens automatically under the effect of torsion springs which are associated with its hinge 22.
- the leaf 20a of door 16 opens in turn produced upon return of actuator 38 in its rest state illustrated schematically on the figure 2.
- the automatic opening means also advantageously comprise, means for guiding these leaves, during their opening.
- these guide means may in particular be constituted by ramps 42, provided for this purpose on the inner face of the leaf 30 from the external access door 14 or on the support retractable 132 ( Figures 16,17). These ramps 42 control the opening of the leaves 20a and 20b of the drum door 16, as the door external access 14 is open.
- each of the leaves 20a and 20b comes in support against an elastomer stop 44 provided for therein effect on the inner surface of the frame 34.
- the actuator 38 can be mounted directly on the face of leaf 30 of door 14 facing inside the washing machine. This arrangement particularly simple however has the disadvantage to place all of the unlocking means in a hostile, corrosive environment, subject to high temperatures and temperature variations important. In addition, the presence of the actuator 38 between doors 14 and 16 can cause problems of space.
- the actuator 38 is mounted on the contrary on the outer face of the leaf 30 of the door 14. In in this case, the push rod 40 passes through the leaf 30 of waterproof way.
- the actuator 38 is therefore not subject to the hostile environment that prevails inside the tank 12.
- a cover 46 can then be fixed on the face outer of the leaf 30 around the actuator 38, to protect it.
- FIG 5 there is shown schematically a second embodiment of the invention, applied to the case of a washing machine whose drum door 16 is equipped with a mechanism claw lock comparable to that which has been previously described with reference to Figures 1 and 2.
- the unlocking means are also mounted in the external access door 14. They include a tree rotary 48, rotatably supported by the door 14, parallel to the axis of the drum. To one of his ends, the shaft 48 passes through the door 14 so waterproof, to be engaged on an actuator 50 fixed on the door, outside of it.
- the actuator 50 is, for example, a rotary motor designed to ability to drive shaft 48 in rotation in one and the other direction on a relatively limited course.
- lever 52 In its central part located at the level of button 28 carried by the leaf 20a of the door drum 16, a lever 52 is fixed to the shaft 48. In inactive position, lever 52 is held in abutment against an elastomer stop (not shown) provided for this purpose on the inner face of the leaf 30 ( Figure 3) of the external access door 14. This maintenance may possibly be provided by means elastic (not shown), when the actuator 50 is not implemented.
- An implementation of the actuator 50 intervenes automatically at the end of the wash-spin to unlock the door drum 16.
- This implementation has the effect of making pivot the shaft 48 in a direction such as the lever 52 press button 28 of door leaf 20a 16. Unlocking the locking mechanism 24 claws is thus ensured.
- the actuator 50 can be replaced by a jack linear 54, mounted outside of door 14, and whose rod carries a rack 56.
- This rack 56 is oriented tangentially to a pinion 58 fixed to the corresponding end of the shaft 48, so as to be in engagement with this pinion 58.
- the assembly is protected by a cover 59.
- the invention also applies to automatic unlocking of a drum door 16 fitted with a locking mechanism with links.
- a central link 60 is articulated, by a axis 62, on the leaf 20a of door 16, near from its edge adjacent to the leaf 20b. More precisely, axis 62 is perpendicular to the leaf surface 20a and the rod 60 is mounted outside of this beating.
- Each end of the rod 60 is articulated, by an axis 64, at a first end of a connecting rod 66.
- the opposite ends of the rods 66 are themselves articulated, by another axis 70, at a first end of a bolt 68.
- the bolts 68 are mounted by guides 69 on the leaf 20a of the drum door 16, so that it can be move in translation along a common axis parallel to the axis of the drum.
- axes 64 and 70 are parallel to axis 62.
- the link mechanism which has just been described is arranged so that a pivoting of the rod 60 around the axis 62 has the effect of move the bolts 68 away from each other or closer to each other, according to the meaning of rotation.
- the bolts 68 can thus occupy a active locking position or position inactive, as shown in Figure 7.
- the unlocking means comprise an actuator 76.
- This actuator 76 is mounted on the external access door 14, or on the support retractable 132 ( Figures 16,17) able to be brought to the place of this door when open.
- the actuator 76 is provided with a rod 78 likely to be aligned with axis 62 of the rod 60, at the end of the wash-spin cycle.
- the implementation of the actuator 76 then makes it possible to move the rod 78 in translation and in rotation.
- the rod 78 AT its end facing the inside of the washing machine, the rod 78 carries a dog clutch 80.
- This dog clutch 80 is designed to engage the swivel link 60 when the rod 78 is moved axially towards the drum door 16. This engagement is then such as a control of rotation of the rod 78 has for effect of rotating the rod 60 around its axis 62, in the unlocking direction.
- guide means are advantageously provided in the external access door 14 or in the retractable support 132 ( Figures 16,17) so that the opening of the two leaves 20a, 20b of the door drum 16 takes place gradually as and measurement of the opening of the external access door 14 or the spacing of the retractable support 132, respectively.
- Figure 9 illustrates a third type of locking mechanism fitted to the drum door 16 of some washing machines.
- the locking includes a slide 82 mounted on one 20a of the leaves of door 16. More specifically, the slide 82 is mounted near the end of the leaf 20a adjacent to leaf 20b, so that ability to slide parallel to drum axis between a locking position illustrated on the Figure 9 and an unlocked position.
- the slide 82 is mounted on leaf 20a by rivets 84 integral with this leaf 20a, and imprisoned in straight slots 86 formed in the slide 82.
- the slide 82 also includes slots 88, in a projecting part capable to be placed above the leaf 20b.
- Each of these slots 88 has an enlarged part and a part more narrow.
- the enlarged portions of the slots 88 are placed in front of rivets 90 fixed on the leaf 20b, when the slide 82 is in its position unlocking.
- the narrower parts slots 88 trap the rivets 90, as illustrated in figure 9, in the position of locking the slide 82.
- the displacement of the slide 82 between these two positions is ensured in acting on a stop 92 which projects towards the outside from this slide.
- the unlocking means comprise an actuator 94, mounted outside the door external access 14.
- This actuator 94 controls the rotation of a rotating shaft 96, supported so revolving through door 14, in one direction orthogonal to the axis of the drum 10.
- a lever 98 is fixed to the shaft 96, in its central part, so that ability to come and engage stop 92 in the direction of unlocking the door locking mechanism 16, when the actuator 94 is implemented automatically at the end of a wash-spin cycle.
- FIG 11 there is shown a mechanism hook locking system capable of fitting the drum door 16 of a washing machine conforming to the invention.
- This type of mechanism includes hooks 100, pivotally mounted on one 20a of the leaves of the door 16 by axes 102 perpendicular to the surface of this clapper.
- a rod 104 connects the hooks 100, in being articulated on each of them.
- This rod 104 is provided with a stop 106 allowing it to be maneuvered.
- Locking rivets 108 are mounted on the second leaf 20b of door 16, opposite hooks 100. The relative arrangement between the rivets 108 and the hooks 100 is such that when the two door leaves are closed, door 16 is locked when the ends of the hooks 100 encircle the locking rivets 108. Au otherwise the door is unlocked when the ends of the hooks 100 are released from the rivets lock 108.
- an actuator 110 mounted at the exterior of the exterior access door 14 drives in rotation a shaft 112, rotatably supported through door 14, in a direction substantially orthogonal to that of the axis of the drum 10.
- a lever 114, fixed to the shaft 112 in its central part, is arranged to bear against the stop 106, in order to move the rod 104 in the direction of unlocking of the mechanism, when the actuator 110 is implemented.
- the door 16 can also be closed automatically after loading the laundry in the machine.
- an actuator 116 constituted here by a linear cylinder, can be mounted outside the frame 34, to control the pre-closing of the leaf 20a of door 16, bearing the claws 24.
- the actuator 116 is provided with a push rod 118 which crosses tightly the frame 34, according to a direction substantially tangential to the drum 10.
- a tip 120 fixed to the end of the rod pusher 118 can come to bear against the leaf 20a of door 16, to order pre-closing, as illustrated in dashed lines, when the actuator 116 is implemented.
- the tip 120 of the push rod 118 is, of preferably wide enough to bring the leaf 20a of door 16 in a position erased at inside the drum, when the actuator 116 is implemented.
- Automatic locking can be obtained when the second leaf 20b is brought to its turn in the closed position by the guides 42 ( Figure 3) formed inside the door 14, when it is then closed.
- locking can be ensured by means of an additional actuator (not shown) installed on the exterior access door 14, when the end piece 120 of the rod 118 has a insufficient dimension to bring the leaf 20a into the position illustrated in phantom in the figure 13.
- the means of passive guidance formed by ramps 42 can be replaced by active guidance means two leaves of the drum door 16.
- these active guidance means can also be used to close the drum door and in the case of Figure 15, to ensure locking.
- the guide means leaves 20a and 20b of the drum door 16 include arms 122, which are pivotally mounted on the frame 34 of the tank 12 around two oriented axes parallel to the axis of the drum. More precise, these axes are materialized by two trees 124 to which are fixed the arms 122.
- the shafts 124 are supported by frame 34 near two edges opposites of it.
- the rotations in the opposite direction of the shafts 124 are simultaneously controlled by a single actuator 126, mounted outside the tank 12.
- This actuator 126 consists here of a jack whose body is mounted pivoting on the tank 12 by an axis 128 and whose rod controls reverse rotation of each of the shafts 124 through a mechanism 130, by example of rod-crank type.
- this actuator additional (not shown) can be the same as the one that is used to perform the unlocking door, if the washing machine is equipped with advanced indexing to bring the drum in an angular position slightly offset by in relation to the position he occupies during his opening, when the exterior access doors are closed.
- the machine then comprises two actuators 126 constituted here by cylinders of which the bodies are pivotally mounted on the tank 12 by axes 128.
- the rod of each of the cylinders 126 actuates separately one of the shafts 124 carrying the arms 122 by through a connecting rod-crank mechanism.
- the means unlocking and possibly the means of guide can be installed on the support retractable 132, as illustrated in FIGS. 16 and 17.
- the retractable support 132 When the washing machine is in operation, the retractable support 132 is placed outside the tank 12, of which the external access door 14 has then a classic configuration.
- the door access door 14 is open and the support retractable 132 is brought into an active position, inside the access opening 36, as we have illustrated in phantom in Figures 16 and 17.
