Definitions

  • the invention relates to a device for stopping in position and for rapidly unlocking the access door of a horizontal drum machine.
  • the present invention also relates to a washing machine and / or drying machine provided with such a device.
  • a washing machine and / or dryer usually comprises a perforated drum containing the laundry and rotating inside a tank intended to retain the washing or rinsing water.
  • the drum is usually driven by a motor placed below the tank, the movement transmission being carried out by means of a belt and two pulleys fixed respectively on the motor shaft and the axis of the drum to the outside of the tank.
  • the access door of the bodywork gives onto the watertight door of the tank which in turn gives onto the drum, the latter itself being provided with an access hatch .
  • EP-A-0 408 120 presents a device for stopping a washing machine drum.
  • the drum can rotate at very high speeds, which can exceed 800 revolutions / minute.
  • the locking device can operate either during the entire washing cycle, or only during the high speed phases. In the latter case, the locking device is connected to the electromechanical programmer or to the electronic device if necessary.
  • the lock of the locking device is often of the thermal type, due to the low price of such a mechanism. This is for example a bimetal or wax lock.
  • This is for example a bimetal or wax lock.
  • the present invention aims to reduce the drawbacks mentioned above.
  • One of the objects of the invention is to propose a device, mechanically simple and requiring few parts, for stopping in position of a horizontal drum machine making it possible not only to align the drum door and the gate of the tank when the machine stops, whether it is an end of washing stop or a stop controlled by the user, but also allowing rapid unlocking of the access door of the machine body during this stop, while guaranteeing the safety of said user.
  • the stopping device in position can be implemented without being used with rapid unlocking. The combination of the two functions, stop in position and quick unlocking, however, allows a significant reduction in cost price.
  • the drum can be stopped in position with or without rapid unlocking of the access door to the bodywork at any time during the operation of the appliance, in particular during the spinning phases.
  • Another advantage of the invention is that it makes it possible to bring the drum into the desired position smoothly, thus limiting the stresses on the parts.
  • the subject of the invention is therefore a device for stopping in position a horizontal drum machine as set out in claim 1.
  • the locking means is connected to the bolt of the automatic lock of the door of the bodywork so that the latter unlocks the door when the locking means enters the locking position.
  • Figure 1 shows a washing machine and / or dryer laundry with a body 1, access to the interior of the machine is through an access door 2.
  • This access door is provided on top of the machine in the case of a machine with access from above such as that shown.
  • a pulley 3 fixed on the motor shaft 4 transmits, by means of a belt 5, the rotation of said motor 4 to the drive pulley 6 of the drum 7 with a horizontal axis.
  • the machine further comprises a tank 8 provided with an access door 9. Inside the tank 8 rotates a drum 7, also provided with an access door 12. Said drum 7 is driven in rotation by the pulley 6, the latter being fixed in a known manner on the axis of the drum 7 outside the tank 8.
  • the flange 10 seals between the access door 9 of the tank 8 and the tank it -even.
  • a control panel 11 allows the user to operate the machine.
  • the machine also includes a manual unlocking button 13 of the access door 2 of the bodywork.
  • this button 13 is located on the front face of the body, but it can be placed on the control panel 11.
  • An automatic safety lock the bolt of which engages in the finger 15 fixed to the door access 2, is also provided and will be described in more detail later.
  • Compression spring 14 raises the access door 2 when the latter is not retained by any lock.
  • FIG. 2 represents certain connections of the digital module 16 for controlling the operation of the washing and / or drying machine.
  • One of the roles of said digital module 16 is, among other things, to control the speed and the direction of rotation of the motor 4.
  • the module 16 receives in return the data coming from the tachometer 17, thus allowing regulation of said speed.
  • a safety microswitch 18 cuts off the general power supply to the machine when the access door 2 of the bodywork opens.
  • the washing and / or drying machine comprises a device for stopping in position and for rapidly unlocking the access door, the stopping device comprising a shoe which by jamming blocks the drum in a given position.
  • the stopping device comprising a shoe which by jamming blocks the drum in a given position.
  • a support plate 21 of the device for stopping in position and for rapid unlocking is fixed in a known manner to the tank 8 or to any element that is fixed relative to the axis of the tank 8.
  • the device itself comprises a pad 22 by example in the form of a wedge supporting a hook 23 so that a lug 24, the position of which is described later, comes to engage in the hook thus causing the wedge 22 with its guide rod 25 so that said wedge 22 for example, get stuck between the pulley 6 and the belt 5 when the motor 4 rotates in the preferred direction and that the wedge 22 has been previously put in the approach position.
  • the wedge 22 has for example a substantially beveled shape. It is flat on the side coming to rest against the belt 5 so as to have a large contact surface and adapts to the radius of curvature of the pulley 6 on the opposite side. This does not in any way prejudge the surface condition of the wedge, which may include means which increase the friction for example between itself and the belt 5 or the pulley 6.
  • the wedge 22 can in particular have a rough surface or even adapt to the sculptures of the belt 5 if necessary.
  • the shim 22 can be made of a flexible material, thus making it possible to reduce the stresses exerted on the belt 5 and the shim 22.
  • the hook 23 is either an insert and fixed in a known manner on the wedge 22, or is integral with it.
  • the wedge 22 and its hook 23 are supported by a guide rod 25 which is inserted into the coil 26 fixed on the support plate 21.
  • the guide rod 25 comprises a magnetic core 27 allowing translation in the direction of the axis of the rod 25 when the coil 26 is supplied via the connections 28 and 29 connected to the digital module 16.
  • the guide rod 25 further comprises a stop 30 intended to hold said rod 25 so that the magnetic core 27 is in a good position relative to the coil 26 when the device is in the rest position.
  • a return spring 31 brings the guide rod 25 and therefore the shim 22 into the rest position when the washing machine is restarted after a stop in position has been made .
  • the guide and translation means are dissociated: rails or a guide rod are then provided, the latter being distinct from the element carrying the magnetic core 27, this element of course also being able to be a rod .
  • the machine comprises a manual unlocking button 13 of the access door 2 of the bodywork.
  • the button 13 has a hook 32 which engages on a stop 33 of the door 2 of the bodywork.
  • the manual unlocking button 13 actuates a microswitch 19 connected to the digital module 16.
  • the change of state of the microswitch 19 causes the digital module 16 to command the stopping the machine in position as described later.
  • an impulse given to the button 13 is sufficient to command the stop in position.
  • the corresponding pulse can also be given via a stop button, not shown, on the control panel, the interface between the stop button and the digital module being done in the same way as for the manual locking button 13, by associating the button stop at a microswitch connected to the digital module 16.
  • Said stop button on the dashboard can also have the function of manually unlocking the access door of the bodywork.
  • the access door 2 of the body can also be locked automatically by means of an automatic lock, the bolt 34 of which is inserted into an opening 35 of the finger 15 of the door 2 of the body.
  • the automatic lock can be actuated either by a thermal element, or, according to a particular embodiment of the invention, by the stop device in position.
  • the bolt 34 is connected to the guide rod 25 by means of a flexible cable 36 sliding in a sheath 37.
  • the cable 36 can slide in an opening made in a support 38 fixed to the guide rod 25.
  • a stop 39 fixed to the end of the cable adjusts the height of the guide rod 25 from which said rod pulls on the cable 36.
  • This height is advantageously adjusted so that the guide rod 25 only pulls the cable 36 as soon as the lug 24 pulls on the rod-wedge-hook assembly 25-22-23.
  • the stroke of the cable 36 is also advantageously calculated so that the bolt 34 is disengaged from the opening 35 at the latest when the wedge 22 is in its locked position.
  • FIGS. 1 and 3 to 5 show the device in this configuration.
  • the access door 2 of the bodywork is then kept closed by the manual lock 13 and the bolt 34, and the wedge 22 and its hook 23 are in a position such that they do not hinder the rotation of the pulley 6.
  • the direction and the speed of rotation of the drum 7 can be arbitrary. We define a preferential direction of rotation of the drum 7 and an opposite direction, the preferential direction being the anti-clockwise direction with respect to FIGS. 1 and 3 to 5 (direction S1).
  • a stop in position is controlled under two circumstances: either when the user sends a corresponding pulse by pressing the manual unlocking button 13 or a stop button on the control panel 11, or when the washing of the laundry is finished. In the latter case, the necessary command can for example be given via a contact of the electromechanical programmer.
  • the digital module 16 controls the unpositioned stop of the machine. This can be achieved by cutting off the power to the motor 4.
  • the digital module 16 controls a rotation of the motor 4 at low speed, corresponding for example to a rotation of the drum at 30 revolutions per minute, in the preferential direction S1.
  • the digital module 16 controls the tensioning of the coil 26.
  • the translation of the core 27 and therefore of the guide rod 25 pushes the wedge 22 and its hook 23 into the so-called approach position, this position being such that the lug 24 integral with the pulley 6 engages in the hook 23, causing the latter in its movement.
  • the operating means of the locking means therefore comprises, in the present embodiment, the coil 26, the core 27 and the guide rod 25.
  • the so-called approach position is shown in FIG. 4.
  • the wedge 22 then comes gradually get stuck between the pulley 6 and the belt 5, the speed and inertia of the drum 7 and the pulley 6 being such that the engagement of the shim 22 is sufficient to on the one hand block the pulley 6 and therefore the drum 7 rotating in the preferential direction S1, and on the other hand to prevent rotation of the drum 7 in the opposite direction because of a possible unbalance of linen, once the power to the motor 4 is cut.
  • the position of the pin 24 on the pulley 6 is such that when the latter and the belt 5 are blocked, the hatch access 12 of the drum 7 is opposite the door 9 of the tank.
  • the lug 24 is advantageously placed on one of the faces of the pulley 6.
  • the rod 25 pulls on the cable 36 via the support 38, integral with the guide rod 25, which comes to be placed against the stop 39.
  • the bolt 34 then releases the finger 15.
  • the compression spring 14 pushes back the access door 2 from the body, allowing the user to access the interior of the machine.
  • the safety microswitch 18 cuts off the general supply of the machine, and more particularly that of the motor 4.
  • the hook 32 of the manual unlocking button 13 must be released from the stop 33 so that the access door 2 of the bodywork opens. This is not a problem when the button 13 is a bistable button, because in this case, the hook 32 remains released from the stop 33 even if the user releases the button.
  • a monostable push button i.e. a button which returns to its initial position as soon as it is released
  • the user must hold it pressed down until stop in position of the drum so that the access door 2 of the bodywork opens.
  • means for detecting the position of the drum Said means is connected to the digital module 16, which processes the information which emanates therefrom.
  • the stop blocking cycle in position is restarted, possibly preceded an imbalance elimination phase, the latter not being in itself part of the present invention.
  • the access door 2 can then be unlocked by manual means whose implementation is obvious to humans of career. The motor power is also cut in this case.
  • the means for detecting the position of the drum may, for example, comprise a reflective label placed on the pulley 6 and a light-emitting diode and a sensor placed opposite the pulley.
  • Other means can obviously be used, such as Reed or Hall effect sensors associated with a permanent magnet judiciously placed on the pulley 6.
  • the latter comprises a device for cutting the current, not shown, other than that controlled by the safety microswitch 18, characterized in that it cuts the supply to the motor 4 and to the coil 26 when an untimely rise in current in the rotor or stator of motor 4 is detected while the speed of rotation of said motor is zero.
  • This additional safety device may be necessary in the case where the bolt 34 remains blocked in the opening 35 while the rotation of the drum 7 is blocked but the motor 4 is still supplied, the safety microswitch 19 only being triggered when the opening of the access door 2 of the bodywork. This will prevent damage to the shim 22 or the belt 5.
  • the production of such a safety device is within the reach of the skilled person.
  • the digital module can also be used to detect a rotor blockage. If, for example, a rotation of the motor has been controlled by said module 16, it will suffice to verify the correct execution of this command by monitoring the tachometer. Such monitoring can easily be programmed. If you want to know if the motor is blocked when no rotation command has been launched, it will suffice to perform this command beforehand.
  • the machine will be turned on again once the safety microswitch 19 is closed, that is to say once the access door 2 of the bodywork is closed.
  • the machine is constructed so that when restarting, the drum 7 first turns in the opposite direction to the preferred direction S1.
  • the digital module 16 is programmed accordingly. This has the effect of unlocking the wedge 22, of disengaging the lug 24 of the hook 23, thus allowing the wedge 22 and the hook 23 to return to their rest position, either by simple gravity, or by means of springs of compression 31 and / or 40.
  • means are provided for increasing the acute angle between the hook 23 and the wedge 22 when the locking means is brought into the approach position, so as to facilitate the hooking of the hook 23 by the lug 24 at this time, while avoiding accidental snagging at other times.
  • a shock absorber is provided on the one hand to absorb the mechanical shocks undergone during an approaching position, on the other hand to fold the hook 23 when the device returns to its rest position.
  • the hook 23 When the device is at rest, the hook 23 is folded against the wedge 22. According to this embodiment, the hook 23 is bent and is provided at the elbow with an axis coming to be housed in a corresponding location, not shown, of the wedge 22, so that the hook 23 can pivot around its axis while being blocked in translation parallel to this axis.
  • the hook 23 has an arm beyond its elbow, the side of which forms an acute angle with the other arm is pressed against one end of a damper. This damper is such that the damping is done by compression over its length when the hook 23 pivots about its axis in the clockwise direction.
  • the damper can for example be a spring or a part made of a compressible elastic material.
  • the side of the arm opposite the side coming to bear against the shock absorber is rounded, so that a stop rotates the hook 23 while sliding along this rounded side when the wedge 22 is translated to its position d 'approach.
  • the stop is fixed relative to the tank 8.
  • the shock absorber In the rest position, the shock absorber has maximum elongation.
  • the acute angle between the arm of the hook 23 where the lug 24 will hang and the side of the wedge 22 coming to press against the pulley 1 then has its minimum opening.
  • the opening of the angle widens, the stop pressing on the rounded side of the arm, while the shock absorber begins to compress.
  • the hook 23 waits for the lug 24 to arrive. The shock due to contact between the hook 23 and the lug 24 is at least partially absorbed by the shock absorber. Everything then happens as in the first example of embodiment.
  • means are provided to improve the maintenance of the device, and therefore of the drum, in the locked position.
  • These holding improvement means comprise a retractable element 47, 48 exerting, on a strip 46 integral with the rod-wedge assembly 25, 22 and comprising at least one recess, a force such that, when the device is in the position of blocking and that the head 48 of the retractable element is positioned in a hollow in the lamella 46, the device is held in position despite a possible unbalance of linen inside the drum 7.
  • Figures 6, 7 and 8 show a part of the device according to the invention accompanied by said means for improving maintenance when said device is respectively in the rest or blocking position.
  • a strip 46 is provided in S-shape whose vertical axis is parallel to the translation axis of the wedge 22 and its guide rod 25.
  • the lamella 46 is integral with the wedge-rod assembly and may for example consist of an extension of the support 38, as shown in FIGS. 6 and 7.
  • the strip 46 moves at the same time as the guide rod 25, it comes to rub against a locking rod 47, the axis of which is advantageously perpendicular to the axis of translation of said rod 47.
  • the latter is provided with a head 48 at the rounded end and with a ring 49 on which a spring 50 bears.
  • the assembly is held between two stops 51 and 52, fixed on the support plate 21 , as illustrated in FIG. 8, so as to allow the rod 47 to translate between two positions, one being reached when the ring is in abutment against the stop 52, the other being reached when the spring 50 is compressed.
  • the first position is the rest position.
  • the strip 46 comes into contact with the head 48, which retracts under the effect of the force exerted.
  • the head 48 then follows the curves of the strip 46.
  • the length of this strip 46 is calculated so that the head 48 comes to be placed in the hollow formed by the lower loop of the S at the very moment when the wedge 22 is in blocking position.
