Definitions

  • the present invention relates to a door lock for front-loading washing machines and driers, comprising a support body adapted to be fixed to the structure of the machine, locking means which are movable relative to the body and adapted to cooperate with a retaining member attached to the door to prevent or enable its opening, and safety means adapted to keep the locking means in an operative condition when the machine is in operation.
  • the object of the present invention is to provide a door release which is simple and cheap to produce and which enables the door to be opened by means of a push-button situated on the control panel of the machine and connected by means of a cable to the movable locking means associated with the support body of the lock.
  • the device according to the invention is characterised in that the locking means comprise a lever member having a first end articulated to the support body and a second end connected to an operating cable, the safety means preventing the pivoting of the lever member when the machine is in operation.
  • a front-loading washing machine is generally indicated 1 and is provided with a front loading door 2 which can pivot about a vertical axis.
  • the machine includes a washing chamber 3 in which a drum 4 is mounted for rotation.
  • a lock 5, associated with the door 2 is carried by the structure of the washing machine and can hold the door closed when the washing machine is in operation.
  • the lock 5 includes a support body 6 fixed to the structure of the washing machine and having an aperture 7 for the passage of a hooked lever or catch member 8 articulated at 9 to a lateral edge of the door 2 with the interposition of a torsion spring 10 arranged to keep the catch member 8 in a position substantially perpendicular to the median plane of the door 2.
  • the support body 6 has a vertical guide 11 in which a rod-like slide 12 is slidable, the slide having a cut-out portion 13 in its lateral edge surface 12a whose width corresponds substantially to the width of the catch member 8.
  • the sliding of the slide 12 in the guide 11 is driven by a lever 14 perpendicular to the slide and having a first end 14a articulated at 15 to the body 5 and a second end 14b to which the end of an operating cable C is connected.
  • the lever 14 has a central horizontal slot 16 in which a pin 17, connected to one end 12b of the slide 12, is slidable in order to enable the slide itself to slide as a result of the rotation of the lever 14 about the fulcrum 15.
  • the lever 14 Near its second end 14b, the lever 14 has a side arm 18 with a hooked end 18a for cooperating with an abutment 19 which is adapted to project, in known manner, from the body 6 of the lock 5 when the machine is operating and to be flush with the support body 6 when the machine has stopped.
  • a helical tension spring 20 is interposed between the lever 14 and the body 6 for biassing the lever 14 to a substantially horizontal position.
  • Figures 5 and 6 show a second embodiment of the device in which elements similar to those shown in Figures 3 and 4 have the same reference numerals.
  • the lever 21 has an auxiliary side arm 22 with a pin 23 arranged to slide in a vertical slot 24 in a horizontal slide 25, parallel to the lever 21.
  • the slide 25 is slidable in a horizontal guide 26 in the body 6 and has a first end 25a situated in correspondence with the aperture 7 for the passage of the locking catch 8 and a second end 25b provided with a lateral appendage 27 for cooperating with the abutment 19.
  • Figure 5 shows the machine with the door closed as in the first embodiment shown in Figure 3.
  • the operation of the lever 21 by means of its end 21b causes the pin 23 connected to the auxiliary lateral arm 22 to pivot about the fulcrum 15 and to slide in the vertical slot 24 causing the horizontal sliding of the slide 25 and the release of the locking catch 8 from the end 25a of the slide.
  • the abutment 19 prevents the slide 25 from sliding by reacting against its lateral appendage 27.
  • FIGS 8, 9 and 10 show a third embodiment of the lock in which similar elements are indicated in the drawings by the same reference numerals as those used in Figures 1-7.
  • a first end 28a of a lever 28 is pivoted at 15 on the support body 6, the lever having a second end 28b for connection to an operating cable.
  • the lever 28 has a first side arm 29 near the first end 28a and a second side arm 30 situated between the first arm 29 and the second end 28b.
  • the first side arm 29 has an L-shaped free end 31 situated in correspondence with the aperture 7 for the passage of a retaining hook 32 which is fixed rigidly to the door 2 and has an end 32a which defines a shoulder 32b for cooperating with the end 31 of the first arm 29 of the lever 28.
  • the L-shaped end 31 prevents the release of the hook 32.
  • the lever 28 can be pivoted by action on its end 28b to cause the disengagement of the hook 32 from the end 31 of the first side arm 29 and allow the door to be opened.
  • the abutment 19 cooperates with the second side arm 30 to prevent the lever 28 from pivoting and hence the door from opening.
  • Figures 11 and 12 show a fourth embodiment of the lock which is similar to that shown in Figures 8 and 9.
  • a rotary abutment member 33 is articulated on a vertical pin 34 of the support body 6 about an axis X-X perpendicular to the axis of rotation of the lever 28.
  • the abutment element 33 has an engagement tooth 33a for cooperation with the catch member 8, a recess 33b for cooperating with the free end 31 of the lever 28 and a cam surface 33c.
  • the lever 28 can be pivoted by action on its end 28b to disengage the end 31 of the lever 28 from the recess 33b in the rotatable member 33.
  • the latter can therefore pivot on the pin 34 to allow the release of the catch member 8 from the engagement tooth 33a and the consequent opening of the door.
  • a torsion spring is interposed between the pin 34 and the rotatable abutment member 33 for biassing this member into the configuration illustrated in Figure 12, the cam surface 33c enabling the resilient snap repositioning of the end 31 of the lever 28 in the recess 33b.
  • lever of the lock may be operated by devices different from those described.
