Definitions

  • the present invention concerns a locking device for the closing lid or door of cloth washing machines and the like, as known e.g. from US 2002/017793 A1 .
  • the invention concerns in particular, although this is not to be understood in a limiting sense, front-loading cloth washing machines.
  • the drum of front-loading cloth washing machines is closed by a (tightly) sealing lid hinged to the front panel of the machine and fitted with a closing latch or hook engaged by a locking device which is mounted on the machine front panel.
  • the locking device comprises an electromechanical device known as a door-lock, that prevents the opening of the lid after the machine has been started, and delays its opening after completion of the operating cycle, until the inertial rotation of the inside drum has ended.
  • a door-lock an electromechanical device known as a door-lock
  • the door-locking device under normal operating conditions the activation of the door-locking device is mechanically prevented if the lid is open, and in case the device is serially connected on one phase of the machine feeding system, the device also fulfils the function of preventing the machine from starting when the lid is open.
  • the door-locking device of a washing machine In order to comply with the existing European and U.S. Standards in the cloth-washing machine sector, in particular Standard EN60335-27 (2003 edition), par. 20 and Standard UL2156 par. 20.8.5, the door-locking device of a washing machine must not allow the activation of the machine when a testing finger of a predetermined size is used in a tampering attempt.
  • An object of the present invention is to realize a door-locking device for cloth washing machines and the like capable of meeting the tests envisioned by the European and U.S. standards, by mechanically preventing the start-up of the machine with the lid open, when trying to tamper the device with a "finger" of the size provided for by the Standards, with a particularly simple and effective construction.
  • the device according to the invention comprises a containing body 1, preferably made of a thermoplastic material, that comprises a portion 15 fitted with means for fastening it to the front lid of the cloth-washing machine and a closing cover 16.
  • the portion 15 is realized with a square opening 2, capable of receiving the lid hook 20 and fitted with a projecting rim 3 to be seated in the front panel of the machine so as to receive and retain the hook.
  • the body 1 further houses a sliding cursor 6 subjected to the action of elastic means 14 and an electromechanical delaying device 4 of an already known type.
  • the delaying device 4 comprises a pawl 5 that is operated by a system connected to the machine actuating controls, for instance through a movable contact blade of a micro-switch mounted in series on one phase of the machine powering system.
  • the cursor 6 presents, at the opening 2 of the support 1, a square opening 7 fitted with a thickened frame 8 with two recesses 9.
  • a locking lever 11 with a U-profile is seated inside the body 1, in correspondence of the opening 2 and connected to this latter with a hinge-type link 21.
  • the link 21 is advantageously realized with helical springs 12 arranged so as to allow, in addition to a rotation and return action of the lever 11 to its rest position, an axial motion of the lever along the sliding axis of the cursor 6.
  • the lever 11 if equipped with two small projections or prongs that fit into the recesses 9 of the cursor 6.
  • the device operates as follows.
  • the elements of the device are in the reciprocal positions shown in Fig. 1 .
  • the lever 11 blocks the small projections 13 of the cursor 6 so as to prevent the cursor translation, while the cursor 6 inhibits actuating the pawl 5 of the door-lock 4, since the axis of the window 10 is offset in respect of the pawl sliding axis. The machine start-up is thus inhibited.
  • the window 10 of the cursor 6 becomes aligned with the axis of the pawl 5 of the door-locking device 4, and this latter can snap into the holding position of the hook 20, while the lever 11 is pushed forward to rest against the cursor 6.
  • the locking pawl 5 slides back and disengages the cursor 6.
  • the hook 20 By rotating the hook 20 to allow it to be extracted from the opening 2, the hook acts on the lever causing its initial translation, which is needed to compensate and dampen the motion of the hook.
  • the subsequent rotation of the hook causes the rotation of the lever 11 and the simultaneous translation of the cursor 6, which returns the elements of the device to their respective positions shown in Fig. 1 .
  • the lever 11 can seat in the portion 15 of the containing body or can be mounted on the closing cover 16 of the same.
  • Fig. 8 provides elastic flaps 17 arranged on the support 1 that oppose the ends of the lever 11, while Fig. 9 shows elastic flaps 18 arranged on the lever 11 so as to oppose pins 19 provided on the cover 16.
